Chronic kidney disease

People with chronic renal failure and uremia show a constellation of symptoms, signs and laboratory abnormalities, in addition to those observed in acute renal failure. This reflects the nature of their long-standing kidney failure, progressive and results in many tissue types.

Therefore, osteodystrophy, neuropathy, bilateral kidneys showed little abdominal ultrasonography, and anemia are typical initial results suggest that a chronic course of a singlenewly diagnosed with kidney failure in the absence of the basis of elevated BUN and serum creatinine.

One of the most typical causes of kidney failure is diabetes mellitus, continuous, closely adopted by hypertension and glomerulonephritis. Polycystic kidney disease, obstruction, and viruses are among the most typical is the chronic renal failure. The pathogenesis of acute renal disease is very different from permanent kidney disease.

Although acute lesions in the kidneycauses of death and detachment of tubular epithelial cells, often followed by regeneration, with restoration of regular architecture, the results provide continuous irreversible loss of nephrons. As a result, more weight is supported by fewer nephrons practices, which manifests as an improvement in glomerular filtration pressure and hyperfiltration.

For factors not well understood, this compensation hyperfiltration, which can be thought of as a form of "high" ofnephron level of the person, predisposes to fibrosis and scarring (glomerular sclerosis). As a result, the rate of destruction of nephrons and reduced increases, thus accelerating the progression of uremia, the complex of symptoms and signs that occurs when the residual renal target is insufficient.

Thanks to the extraordinary reserve of the kidneys practice, up to 50% of the nephrons can be lost with the evidence of short-term functional impairment. So people with twoHealthy kidneys are able to donate one for the transplant. When GFR is reduced even more, leaving only 20% of the initial renal capacity, some degree of azotemia (increased blood vessels of the products normally excreted by the kidneys) shows.

However, patients may be largely asymptomatic, simply because a new equilibrium is reached in the blood vessels levels of these products are no longer sufficient to cause overt toxicity. However, even in thisapparently stable level of evolution of renal hyperfiltration to accelerate end-stage chronic renal failure in progress.

Moreover, simply because people with this level of reserves TFG small practice, you can easily become uremic with any additional power (eg, viruses, obstruction, dehydration, or nephrotoxic drugs) or any other state catabolic in connection with a higher turnover of nitrogen - containing products with reduced GFR.

Thepathogenesis of renal failure resulting in ongoing part of the poisonous mix of results (1) stored products normally excreted by the kidneys (eg, nitrogen containing elements of the process of protein metabolism), (2) the regular products, such as hormones already present in abundance, and (3) the lack of normal kidney products (eg, loss of erythropoietin).

Results failure excretory fluid shifts, an increase of intracellular Na + and water and decreasingIntracellular K +. These alterations may contribute to the purpose of subtle alterations in a series of enzymes, transport systems, and so on. Patients with chronic renal failure usually have some degree of Na + and water also, reflecting the loss of renal excretion of salt and water.

A moderate degree of Na + and drinking too much water can happen without objective indicators of excess extracellular fluid. However, excessive intake continued Na + contributes to failureheart failure, hypertension, ascites, peripheral edema and weight gain. On the other hand, excessive intake of drinking water contributes to hyponatremia.

A recommendation for the typical patient with renal failure continues to avoid excessive salt intake and limiting fluid intake to make sure it is equal to the production of urine and 500 ml (insensible losses). Other adjustments to the standard can be done either through the use of diuretics (in a patient who otherwise makes the urine) ordialysis.

Why do these people also have impaired renal salt and water conservation mechanisms, are much more sensitive than normal to + sudden extrarenal sodium and water loss (eg, vomiting, diarrhea, increased sweating and fever). In these circumstances, much easier to create low ECF, the deterioration of renal ulterior motives (which may not be reversible), and vascular collapse or even shock.

Symptoms and indicators of dry mucous membranes,dizziness, syncope, tachycardia, decreased filling of the jugular vein, suggesting that the increase in the amount of exhaustion. Hyperkalemia is a serious problem in chronic renal failure, especially for those whose GFR fell below 5 ml / min. Above that level, such as falling glomerular filtration rate, aldosterone-mediated increase in K + transport in the distal tubule in the form of compensation.

Therefore, a patient with a GFR 50 ml / min and 5 ml / min in tubular transport function to maintain the balance of K +.Treatment with K +-sparing diuretics, ACE inhibitors or blockers, drugs that can alter the aldosterone-mediated K + transport can therefore precipitate hyperkalemia dangerous for people with chronic renal failure.

People with diabetes mellitus (the main trigger for the permanent kidney failure) may have a hyporeninemic hypoaldosteronism syndrome. This syndrome is actually a situation where the lack of production of renin by the kidney reduces levels of angiotensin II andconsequently hinders the secretion of aldosterone.

As a result, individuals are able to offset the decline in GFR, improving their aldosterone-mediated K + transport and therefore have relative difficulty of K + handling. This difficulty is usually manifested as hyperkalemia even before the GFR has fallen below 5 ml / min.

Finally, not only to patients with chronic renal failure much more sensitive to the effects of Na + overload or quantity, but also on the riserisk of hyperkalemia in the face of sudden loads of K + from endogenous sources (eg, hemolysis, viruses, trauma) or exogenous sources (for example, store the blood vessels, foods rich in K +, K + or medicines that contain).

The reduced ability to excrete acid and base results in continuous renal generate no metabolic acidosis. In most cases, when the GFR is above 20 ml / min, acidosis develops only a reasonable time before the re-establishment of a new steady state production and use of the buffer.The decrease in pH of the blood vessels in these individuals can usually be corrected with 20-30 mmol (2.3 g) of sodium bicarbonate orally every day.

However, these people are extremely sensitive to acidosis in the case of a sudden acid load or the appearance of problems to improve the acid load generated. Several problems of phosphate, Ca2 + metabolic process, and the bone can be seen in permanent kidney failure as a result of a complex series of events.

Key factorspathogenesis of these problems include (1) a decreased uptake of Ca2 + in the intestine, (some) overproduction of parathyroid hormone (three), disordered vitamin D metabolism, and (4) chronic metabolic acidosis. All these factors contribute to increased bone resorption.

Hypophosphatemia and hypermagnesemia can occur through excessive use of phosphate binders and antacids containing magnesium, although hyperphosphatemia is more typical. Hyperphosphataemia contributes to improvinghypocalcemia and thus serves as a trigger for additional secondary hyperparathyroidism, elevated PTH levels in the blood.

Vessels from the high PTH blood bones further reduced Ca 2 +, and contributes to the lack of chronic renal osteomalacia (see discussion below). Congestive heart failure and pulmonary edema may develop in the context of the amount of salt and overload.

Hypertension is a typical finding of chronic kidney failure, also, in general, based on fluid and Na + overload. However,hyperreninemia is also a recognized syndrome in which renal perfusion falls triggers excessive production of renal renin and therefore do not raise systemic blood pressure.

Pericarditis result of irritation and inflammation of the pericardium by uremic toxins is a complication whose incidence continues to kidney failure is decreasing due to the first institution of renal dialysis. Increased cardiovascular risk is a complication seen in patients with chronic renal failure and remainstrigger death in this population.

It is the result of a myocardial infarction, stroke and peripheral vascular disease. Cardiovascular risk factors in these patients are hypertension, hyperlipidemia, glucose intolerance, increased heart valve calcification and chronic myocardial ischemia is a consequence of increased Ca2 + x PO43 product as well as other less well characterized uremic middle .

People with permanent kidney failuremarked abnormalities in red blood cells, white cells and clotting parameters purpose vessels. Normochromic, normocytic anemia, with signs and symptoms of apathy and fatigue easily and usually hematocrit levels in the range of 20-25% is a constant feature.

The anemia is due to the lack of production of erythropoietin and the lack of its stimulating effect on erythropoiesis. Therefore, people with chronic renal failure, dialysis, regardless of location, show aa significant improvement in hematocrit during therapy with erythropoietin (epoetin alfa).

Other causes of anemia may include the effects of suppression of the bone marrow of uremic toxins, bone marrow fibrosis of blood vessels due to elevated PTH, the toxic effects of aluminum (phosphate binding antacids and dialysis solutions) and hemolysis and blood loss associated with dialysis (while the individual is anticoagulated with heparin).

People with chronic renal failure show abnormal haemostasisshows the highest reduction of bruises, the increase in surgery of blood vessels, and a high incidence of spontaneous gastrointestinal hemorrhage and stroke (including hemorrhagic stroke and subdural hematomas).

Laboratory abnormalities include prolonged bleeding time, decreased platelet factor III, platelet aggregation and adhesion abnormal prothrombin and the use of altered, this is not fully reversible, even in patients on dialysis as well. Uremia is associated with highsusceptibility to infections, considered by the removal of leukocytes from uremic toxins.

The repression appears to be greater for neutrophils and lymphoid cells also appear to affect the chemotaxis, the acute inflammatory response, delayed hypersensitivity and leukocyte functions more than others. Acidosis, hyperglycemia, hyperosmolarity, and malnutrition are also thought to contribute to immunosuppression in renal continuum.

The invasive nature of dialysisand the use of immunosuppressive drugs in patients undergoing kidney transplantation also contribute to an increased incidence of infections. Signs and symptoms of CNS and the variety of indicators could sleep disorders and mild impairment of mental concentration, poor memory, misconceptions, and neuromuscular irritability (manifested as hiccups, cramps, twitches and spasms) of asterixis, myoclonus, stupor, convulsions and coma in terminal uremia.

Asterixis is manifested in involuntarybeat movement is seen when the arms are extended and wrists restricted to "stop the visitors." E 'due to the damaged nerve conduction in the wide range of metabolic encephalopathy causes, including renal failure.

Peripheral neuropathy (upper and lower extremity sensory and motor high), which is characterized by restless legs syndrome (localized sense some discomfort and involuntary movements of the lower limbs), is a frequent finding in continuous renalfailure and an important signal for the start of dialysis.

Patients on hemodialysis may develop aluminum toxicity, characterized by the word dyspraxia (inability to repeat words), myoclonus, dementia and seizures. Similarly, aggressive acute dialysis imbalance can result in a syndrome characterized by nausea, vomiting, drowsiness, headache, seizures, and within an individual with a much larger roll.

Presumably, this really is an impact of rapid change in pH or osmolalityin the extracellular fluid, causing cerebral edema. GI nonspecific findings in uremic patients include anorexia, hiccups, nausea, vomiting, and diverticulosis. Although its pathogenesis is not obvious, many of these outcomes improve with dialysis. Lord with uremia have reduced amounts of estrogen, which perhaps explains the high incidence of amenorrhea and the observation that almost never are able to carry a pregnancy to term.

Regular periods, but a higher rate of productivitypregnancy usually return with frequent dialysis. Similarly, low testosterone levels, impotence, oligospermia, and germinal cell dysplasia are common findings in men with permanent kidney failure. Finally, continuous renal failure kidney removed as a site of degradation of insulin, which increases the half-life of insulin.

This usually has a stabilizing effect in patients with diabetes whose blood glucose was previously difficult to control. Skin markings are derived from numerousthe results of continuous renal currently under discussion.

Renal failure patients may appear pale due to continuous changes in anemia, accumulation of metabolites on the color or gray pigment as a result of transfusion-mediated hemochromatosis, bruising and hematomas as a result of bleeding disorders, and pruritus and excoriations be the result of Ca2 + deposits of secondary hyperparathyroidism. Finally, when the concentrations of urea arehigher sweat evaporation leaves a residue of urea called "uremic frost".

This usually has a stabilizing effect in patients with diabetes whose blood glucose was previously difficult to control. Skin markings are derived from numerousthe results of continuous renal currently under discussion.

Renal failure patients may appear pale due to continuous changes in anemia, accumulation of metabolites on the color or gray pigment as a result of transfusion-mediated hemochromatosis, bruising and hematomas as a result of bleeding disorders, and pruritus and excoriations be the result of Ca2 + deposits of secondary hyperparathyroidism. Finally, when the concentrations of urea arehigher sweat evaporation leaves a residue of urea called "uremic frost".

Chronic kidney disease

People with chronic renal failure and uremia show a constellation of symptoms, signs and laboratory abnormalities, in addition to those observed in acute renal failure. This reflects the nature of their long-standing kidney failure, progressive and results in many tissue types.

Therefore, osteodystrophy, neuropathy, bilateral kidneys showed little abdominal ultrasonography, and anemia are typical initial results suggest that a chronic course of a singlenewly diagnosed with kidney failure in the absence of the basis of elevated BUN and serum creatinine.

One of the most typical causes of kidney failure is diabetes mellitus, continuous, closely adopted by hypertension and glomerulonephritis. Polycystic kidney disease, obstruction, and viruses are among the most typical is the chronic renal failure. The pathogenesis of acute renal disease is very different from permanent kidney disease.

Although acute lesions in the kidneycauses of death and detachment of tubular epithelial cells, often followed by regeneration, with restoration of regular architecture, the results provide continuous irreversible loss of nephrons. As a result, more weight is supported by fewer nephrons practices, which manifests as an improvement in glomerular filtration pressure and hyperfiltration.

For factors not well understood, this compensation hyperfiltration, which can be thought of as a form of "high" ofnephron level of the person, predisposes to fibrosis and scarring (glomerular sclerosis). As a result, the rate of destruction of nephrons and reduced increases, thus accelerating the progression of uremia, the complex of symptoms and signs that occurs when the residual renal target is insufficient.

Thanks to the extraordinary reserve of the kidneys practice, up to 50% of the nephrons can be lost with the evidence of short-term functional impairment. So people with twoHealthy kidneys are able to donate one for the transplant. When GFR is reduced even more, leaving only 20% of the initial renal capacity, some degree of azotemia (increased blood vessels of the products normally excreted by the kidneys) shows.

However, patients may be largely asymptomatic, simply because a new equilibrium is reached in the blood vessels levels of these products are no longer sufficient to cause overt toxicity. However, evenapparently stable at this level and extent accelerated renal hyperfiltration, changes in end-stage chronic renal failure in progress.

Moreover, simply because people with this level of reserves TFG small practice, you can easily become uremic with any additional power (eg, viruses, obstruction, dehydration, or nephrotoxic drugs) or any other state catabolic in connection with a higher turnover of nitrogen - containing products with reduced GFR.

Thepathogenesis of renal failure resulting in ongoing part of the poisonous mix of results (1) stored products normally excreted by the kidneys (eg, nitrogen containing elements of the process of protein metabolism), (2) the regular products, such as hormones already present in abundance, and (3) the lack of normal kidney products (eg, loss of erythropoietin).

Results failure excretory fluid shifts, an increase of intracellular Na + and water and decreasingIntracellular K +. These alterations may contribute to the purpose of subtle alterations in a series of enzymes, transport systems, and so on. Patients with chronic renal failure usually have some degree of Na + and water also, reflecting the loss of renal excretion of salt and water.

A moderate degree of Na + and drinking too much water can happen without objective indicators of excess extracellular fluid. However, excessive intake continued Na + contributes to failureheart failure, hypertension, ascites, peripheral edema and weight gain. On the other hand, excessive intake of drinking water contributes to hyponatremia.

A recommendation for the typical patient with renal failure continues to avoid excessive salt intake and limiting fluid intake to make sure it is equal to the production of urine and 500 ml (insensible losses). Other adjustments to the standard can be done either through the use of diuretics (in a patient who otherwise makes the urine) ordialysis.

Why do these people also have impaired renal salt and water conservation mechanisms, are much more sensitive than normal to + sudden extrarenal sodium and water loss (eg, vomiting, diarrhea, increased sweating and fever). In these circumstances, much easier to create low ECF, the deterioration of renal ulterior motives (which may not be reversible), and vascular collapse or even shock.

Symptoms and indicators of dry mucous membranes,dizziness, syncope, tachycardia, decreased filling of the jugular vein, suggesting that the increase in the amount of exhaustion. Hyperkalemia is a serious problem in chronic renal failure, especially for those whose GFR fell below 5 ml / min. Above that level, such as falling glomerular filtration rate, aldosterone-mediated increase in K + transport in the distal tubule in the form of compensation.

Therefore, a patient with a GFR 50 ml / min and 5 ml / min in tubular transport function to maintain the balance of K +.Treatment with K +-sparing diuretics, ACE inhibitors or blockers, drugs that can alter the aldosterone-mediated K + transport can therefore precipitate hyperkalemia dangerous for people with chronic renal failure.

People with diabetes mellitus (the main trigger for the permanent kidney failure) may have a hyporeninemic hypoaldosteronism syndrome. This syndrome is actually a situation where the lack of production of renin by the kidney reduces levels of angiotensin II andconsequently hinders the secretion of aldosterone.

As a result, individuals are able to offset the decline in GFR, improving their aldosterone-mediated K + transport and therefore have relative difficulty of K + handling. This difficulty is usually manifested as hyperkalemia even before the GFR has fallen below 5 ml / min.

Finally, not only to patients with chronic renal failure much more sensitive to the effects of Na + overload or quantity, but also on the riserisk of hyperkalemia in the face of sudden loads of K + from endogenous sources (eg, hemolysis, viruses, trauma) or exogenous sources (for example, store the blood vessels, foods rich in K +, K + or medicines that contain).

The reduced ability to excrete acid and base results in continuous renal generate no metabolic acidosis. In most cases, when the GFR is above 20 ml / min, acidosis develops only a reasonable time before the re-establishment of a new steady state output buffers anduse. The decrease in pH of the blood vessels in these individuals can usually be corrected with 20-30 mmol (2.3 g) of sodium bicarbonate orally every day.

However, these people are extremely sensitive to acidosis in the case of a sudden acid load or the appearance of problems to improve the acid load generated. Several problems of phosphate, Ca2 + metabolic process, and the bone can be seen in permanent kidney failure as a result of a complex series of events.

Key factorsthe pathogenesis of these problems include (1) a decreased uptake of Ca2 + in the intestine, (some) overproduction of parathyroid hormone (three), disordered vitamin D metabolism, and (4) chronic metabolic acidosis. All these factors contribute to increased bone resorption.

Hypophosphatemia and hypermagnesemia can occur through excessive use of phosphate binders and antacids containing magnesium, although hyperphosphatemia is more typical. Hyperphosphataemia contributes to improvinghypocalcemia and thus serves as a trigger for additional secondary hyperparathyroidism, elevated PTH levels in the blood.

Vessels from the high PTH blood bones further reduced Ca 2 +, and contributes to the lack of chronic renal osteomalacia (see discussion below). Congestive heart failure and pulmonary edema may develop in the context of the amount of salt and overload.

Hypertension is a typical finding with chronic renal failure, also, in general, based on fluid and Na +overload. However, hyperreninemia also recognized in the syndrome of renal perfusion falls causes excess production of renal renin and therefore do not raise systemic blood pressure.

Pericarditis result of irritation and inflammation of the pericardium by uremic toxins is a complication whose incidence continues to kidney failure is decreasing due to the first institution of renal dialysis. Increased cardiovascular risk is a complication in patients with chronicrenal failure and is the trigger for death in this population.

It is the result of a myocardial infarction, stroke and peripheral vascular disease. Cardiovascular risk factors in these patients are hypertension, hyperlipidemia, glucose intolerance, increased heart valve calcification and chronic myocardial ischemia is a consequence of increased Ca2 + x PO43 product as well as other less well characterized uremic middle .

People withContinuous renal failure have marked abnormalities in red blood cells, white blood cells and coagulation parameters purpose vessels. Normochromic, normocytic anemia, with signs and symptoms of apathy and fatigue easily and usually hematocrit levels in the range of 20-25% is a constant feature.

The anemia is due to the lack of production of erythropoietin and the lack of its stimulating effect on erythropoiesis. Therefore, people with chronic renal failurefailure, dialysis, regardless of their ability, show a marked improvement in hematocrit during treatment with erythropoietin (epoetin alfa).

Other causes of anemia may include the effects of suppression of the bone marrow of uremic toxins, bone marrow fibrosis of blood vessels due to elevated PTH, the toxic effects of aluminum (phosphate binding antacids and dialysis solutions) and hemolysis and blood loss associated with dialysis (while the individual is anticoagulatedheparin).

People with chronic renal failure show abnormal hemostasis manifested as bruising greatly reduced, the increase in surgery of blood vessels, and a high incidence of spontaneous gastrointestinal hemorrhage and cerebrovascular diseases (including haemorrhagic stroke and subdural hematomas).

Laboratory abnormalities include prolonged bleeding time, decreased platelet factor III, platelet aggregation and adhesion abnormal prothrombin and the use of altered, none of this iscompletely reversible even in people on dialysis. Uremia is associated with high susceptibility to infections, considered by the removal of leukocytes from uremic toxins.

The repression appears to be greater for neutrophils and lymphoid cells also appear to affect the chemotaxis, the acute inflammatory response, delayed hypersensitivity and leukocyte functions more than others. Acidosis, hyperglycemia, hyperosmolarity, and malnutrition are also consideredcontribute to immunosuppression in permanent kidney failure.

The invasive nature of dialysis and the use of immunosuppressive drugs in patients undergoing kidney transplantation also contribute to an increased incidence of infections. Signs and symptoms of CNS and the variety of indicators could sleep disorders and mild impairment of mental concentration, poor memory, misconceptions, and neuromuscular irritability (manifested as hiccups, cramps, twitches and spasms) of asterixis, myoclonus,stupor, convulsions, coma and terminal uremia.

Asterixis manifests as involuntary movements seen to hit the outstretched arms and wrists restricted to "stop the visitors." E 'due to the damaged nerve conduction in the wide range of metabolic encephalopathy causes, including renal failure.

Peripheral neuropathy (upper and lower extremity sensory and motor high), which is characterized by restless legs syndrome (localized sense some discomfort andinvoluntary movements of the lower limbs), is a frequent finding in permanent kidney failure and an important signal for the start of dialysis.

Patients on hemodialysis may develop aluminum toxicity, characterized by the word dyspraxia (inability to repeat words), myoclonus, dementia and seizures. Similarly, aggressive acute dialysis imbalance can result in a syndrome characterized by nausea, vomiting, drowsiness, headache, seizures, and within an individual reallyBUN greater amount.

Presumably, this is really an impact on the ECF pH or osmolality is changing rapidly, causing cerebral edema. GI nonspecific findings in uremic patients include anorexia, hiccups, nausea, vomiting, and diverticulosis. Although its pathogenesis is not obvious, many of these outcomes improve with dialysis. Lord with uremia have reduced amounts of estrogen, which perhaps explains the high incidence of amenorrhea and the observation that is rarely possible to carry a pregnancy to term.

Regular periods, but a higher pregnancy rate production, usually returning with frequent dialysis. Similarly, low testosterone levels, impotence, oligospermia, and germinal cell dysplasia are common findings in men with permanent kidney failure. Finally, continuous renal failure kidney removed as a site of degradation of insulin, which increases the half-life of insulin.

Similarly, aggressive acute dialysis imbalance can result in a syndrome characterized by nausea, vomiting, drowsiness, headache, seizures, and within an individual with a much larger roll.

Presumably, this really is an impact of rapid change in pH or osmolalityin the extracellular fluid, causing cerebral edema. GI nonspecific findings in uremic patients include anorexia, hiccups, nausea, vomiting, and diverticulosis. Although its pathogenesis is not obvious, many of these outcomes improve with dialysis. Lord with uremia have reduced amounts of estrogen, which perhaps explains the high incidence of amenorrhea and the observation that almost never are able to carry a pregnancy to term.

Regular periods, but a higher rate of productivitypregnancy usually return with frequent dialysis. Similarly, low testosterone levels, impotence, oligospermia, and germinal cell dysplasia are common findings in men with permanent kidney failure. Finally, continuous renal failure kidney removed as a site of degradation of insulin, which increases the half-life of insulin.

This usually has a stabilizing effect in patients with diabetes whose blood glucose was previously difficult to control. Skin markings are derived from numerousthe results of continuous renal currently under discussion.

Renal failure patients may appear pale due to continuous changes in anemia, accumulation of metabolites on the color or gray pigment as a result of transfusion-mediated hemochromatosis, bruising and hematomas as a result of bleeding disorders, and pruritus and excoriations be the result of Ca2 + deposits of secondary hyperparathyroidism. Finally, when the concentrations of urea arehigher sweat evaporation leaves a residue of urea called "uremic frost".

Kidney disease - the underlying cause of resistant chronic hypertension (high blood pressure).

The kidneys are organs that regulate systemic blood pressure. The kidneys are bean-shaped organs in the back of the abdominal cavity beneath the lower edge of the rib cage and the upper limit of the pelvic cavity. The two kidneys regulate the volume of blood, excrete waste acids, metabolize drugs, electrolyte balance and produce certain hormones. Yes, the kidneys do much more than urine. In Chinese medicine, is still believed that the strength of the kidneys of controlbones, and fertility. This article will focus on how kidney disease can cause high blood pressure or cause intractable.

Hypertension accelerates renal failure. The reverse is also true. In physiology, it is always thought that kidney patients need high blood pressure to maintain tissue perfusion. This simply means that for the rest of the tissues of the body to continue to receive nutrients and oxygen through the blood, kidneys, blood pressure should increase. This is anatural survival mechanism that is incompatible with optimal health.

The renal vascular bed is a low pressure. In other words, the kidneys are very sensitive to changes in blood pressure and tend to react to spasm of the renal arteries (sclerosis) and increased blood pressure through the renin-angiotensin mechanism aldolsterone. Do not let this ride, I'll explain.

Renin is a hormone that is secreted by the juxtaglomerular cells in response to a decrease in blood volume, lowpotassium, adrenaline down, or decrease renal perfusion pressure. Renin then becomes a protein of 10 amino acids (liver) called angiotensinogen to 8-amino acid polypeptide called angiotensin I. Angiotensin - still inactive, but active in the lungs of the angiotensin converting enzyme (ACE) to angiotensin II activates. Angiotensin II is a potent vasoconstrictor. At the same time, renin stimulates the adrenal glands (adrenal glands) to secrete a hormone called aldosteronewhich in turn stimulate the nephrons of the kidney to reabsorb salt and water to expand blood volume. All this in an attempt to increase blood pressure.

Now, apart from atherosclerosis and blood viscosity, the leading cause of essential hypertension is the glomerular sclerosis. The glomerulus is the filtration apparatus of the kidneys. Glomerulo-sclerosis is a fancy way of saying that the glomerulus have been hardened by the debris, fibrin clots (fibrosis) and obstruction acid residues of the filters. Therefore, the pressureaccumulates. The flow is now more than off-flow. Nephron tubules or harden at the same time. call this nephrosclerosis. Diabetes can also accelerate this process, such as diabetic nephropathy.

Note that before hypertension is diagnosed, however, half of the kidneys are gone. If hypertension is accompanied by swelling of the legs, swollen eyes and fatigue in the absence of heart failure, renal must have been sick. The sad part is that renal function tests, asBUN and serum creatinine may be normal even in this time.

To avoid end-stage renal failure and hypertension assistant, an ounce of prevention is always better than a pound of cure. Stop all food that is bad for the kidneys, such as junk foods and devitalized fragmented. This fried foods, processed, medications such as aspirin, excess refined sugar, heavy metals (lead and cadmium) heavy animal protein, coffee and diuretics, especially antihypertensives.

Arestore the return to normal kidney before it is too late to do some debridement "with a mixture of enzymes containing proteolytic enzymes such as Nattokinase and Serrapeptase. Herbs environment as milk thistle, bearberry, parsley, beards corn, and buchu kidney. Raw fruits and vegetables also help to reinvigorate and kidney function without harmful drugs. To get rid of heavy metals, EDTA chelation is carried out, malic acid, vitamin C, N -acetylcysteine, magnesium, vitamin B6, CoQ10 andZinc.

Chronic renal failure

People with chronic renal failure and uremia show a constellation of symptoms, signs and laboratory abnormalities, in addition to those observed in acute renal injury. This reflects the nature of their long-standing renal failure and progressive and its effects on many types of tissues.

Therefore, osteodystrophy, neuropathy, bilateral kidneys showed little abdominal ultrasonography, and anemia are typical initial results suggest that a chronic course of a newlydiagnosis of the kidneys are not on the basis of elevated serum urea and creatinine.

One of the most typical causes permanent kidney failure is diabetes mellitus, hypertension and approved by glomerulonephritis. Polycystic kidney disease, obstruction and viruses are among the least typical causes of chronic renal failure. The pathogenesis of acute renal disease is very different from permanent kidney disease.

Whereas the acute injury of the kidney resultsand the change in the death of tubular epithelial cells, often followed by regeneration, with restoration of normal architecture, the damage results in irreversible loss of nephrons continues. As a result, a more practical burden is borne by a smaller number of nephrons, which manifests as an improvement in glomerular filtration pressure and hyperfiltration.

For factors not well understood, this compensation hyperfiltration, which may be thought of as a form of "high" levelEach nephron predisposes to fibrosis and scarring (glomerular sclerosis). As a result, the rate of destruction of nephron reduction and lift, thus accelerating the progression of uremia, the complex of symptoms and signs that occurs when the residual renal purpose is insufficient.

Thanks to the enormous reserve of the renal circulation, up to 50% of the nephrons can be lost with no evidence of short-term functional impairment. This is because people with two healthythe kidneys are able to donate for a single transplant. When GFR is reduced even more, leaving only 20% of the failure of the initial capacity, a degree of azotemia (elevation in blood vessels of the products normally excreted by the kidneys) is noticed.

However, asymptomatic patients may be in large part, simply because a new equilibrium is reached, in which blood vessels levels of such products are not high enough to cause overt toxicity. However, even in thisapparently stable level of late renal hyperfiltration evolution accelerated in chronic renal insufficiency in terminal stage is in progress.

Moreover, simply because individuals with this level of GFR is small reserve practice, which can easily become uremic with any additional power (eg, viruses, obstruction, dehydration, or nephrotoxic drugs) or any catabolic state associated with a higher turnover of nitrogen - containing products with reduced GFR.

L 'pathogenesis of renal failure following is based in part on the results of the poisonous mixture of 1) farm products (usually excreted by the kidneys (eg, nitrogen-containing objects in the metabolism of proteins), (2) the ordinary products such as hormones now present in large amounts, and (3) the lack of normal kidney products (eg, loss of erythropoietin).

excretory failure results in fluid shifts, increased intracellular Na + and water and decreasingIntracellular K +. These alterations may contribute to subtle alterations in the context of a series of enzymes, transport systems, and so on. Patients with chronic renal failure usually have some degree of Na + and water also, reflecting the loss of the route of renal excretion of water and salt.

A moderate degree of Na + and excess water, which could happen without objective indicators of excess extracellular fluid. However, excessive intake of Na + continues to contribute to failureheart failure, hypertension, ascites, peripheral edema and weight gain. On the other hand, excessive ingestion of drinking water contributes to hyponatremia.

A typical recommendation for the patient with renal failure remains is to avoid excessive salt intake and limiting fluid intake to ensure that it is equal to the production of urine and 500 ml (insensible losses). Other adjustments in the amount of the order may be made either through the use of diuretics (in a patient, however, urine) ordialysis.

Why are these people also have impaired renal mechanisms of salt and water conservation, the losses are much more sensitive than usual to sudden extrarenal Na + and water (eg, vomiting, diarrhea, sweating and fever). In these circumstances, much easier to create low ECF, the further deterioration of renal effects (which may not be reversible), and even circulatory collapse and shock.

Symptoms and indicators of dry mucous membranes,dizziness, syncope, tachycardia, jugular venous filling suggest that the progression of the decline in quantity. Hyperkalemia is a serious problem in chronic renal failure, especially for people whose glomerular filtration rate fell below 5 ml / min. Above that level, as GFR decreases, aldosterone-mediated K + transport in distal tubule-compensation increases.

Thus, a patient whose GFR is between 50 ml / min and 5 ml / min depending on tubular transport to maintain K + balance.Treatment with potassium-sparing diuretics, ACE inhibitors or blockers, drugs that can affect aldosterone-mediated K + transport may, therefore, precipitate dangerous hyperkalemia in an individual with chronic renal failure.

People with diabetes mellitus (the main trigger for continuous renal failure) may have a hyporeninemic hypoaldosteronism syndrome. This syndrome is really a situation where the lack of production of renin by the kidney reduces levels of angiotensin II andconsequently hinders the secretion of aldosterone.

As a result, people involved are able to offset the decline in GFR increased aldosterone-mediated K + transport and therefore have difficulty in movement of K +. This difficulty is usually manifested as hyperkalemia even before GFR has fallen below 5 ml / min.

Finally, not only patients with chronic renal failure much more sensitive to the effects of Na + overload or quantity, but also morerisk of hyperkalemia in the face of sudden loads of K + from both endogenous sources (eg, hemolysis, viruses, trauma) or exogenous sources (eg, blood vessels stored foods rich in K + or K + containing medicines).

The reduced ability to excrete acid and non-renal continuous basis to generate results in metabolic acidosis. In most cases when the GFR is above 20 ml / min, acidosis develops only reasonable time before returning to establish a new equilibrium of production and bufferuse. The decrease in pH of the blood vessels of these people usually can be corrected with 20-30 mmol (3.2 g) of sodium bicarbonate orally every day.

However, these people are extremely sensitive to acidosis in the case of a load of acid or sudden onset of problems that increase the acid load generated. Several problems of phosphate, Ca2 +, and bone metabolism can be seen in continuous renal not the result of a complex series of events.

Key factorsthe pathogenesis of these problems include: (1) a decrease in Ca2 + absorption in the intestine, (some) the overproduction of parathyroid hormone (three), disorders of metabolism of vitamin D, and (4) chronic metabolic acidosis . All these factors contribute to increased bone resorption.

Hypophosphatemia and hypermagnesemia can occur from excessive use of phosphate binders and antacids containing magnesium, but is more typical of hyperphosphatemia. Hyperphosphataemia contributes to improvinghypocalcemia, and then acts as a trigger for additional secondary hyperparathyroidism, raising the levels of PTH in the blood.

The elevated PTH blood vessels further reduces bone Ca 2 +, and contributes to chronic renal osteomalacia (see below). Congestive heart failure and pulmonary edema can develop in a context of overload and salt.

Hypertension is a typical finding in chronic renal failure, also, in general, based on fluid and Na +overload. However, hyperreninemia also recognized as a syndrome that includes renal perfusion triggers kidney failure excess renin and thus increase systemic blood pressure.

Pericarditis caused by irritation and inflammation of the pericardium by uremic toxins is a complication whose incidence in continuous renal failure is decreasing due to the institution before kidney dialysis. Increased cardiovascular risk is a complication in patients with chronic diseasesrenal failure and is causing mortality in this population.

Is the result of a heart attack, stroke and peripheral vascular disease. Cardiovascular risk factors in these patients are hypertension, hyperlipidemia, glucose intolerance, chronic increase in cardiac output, and myocardial and valvular calcification is a consequence of increased Ca2 + PO43 product x, and other, less well-characterized uremic environmental factors.

People withcontinuous renal failure have marked abnormalities in red blood cells, white blood vessels purpose and parameters of coagulation. Normochromic, normocytic anemia, with signs and symptoms of apathy and fatigue easily and hematocrit levels typically in the range of 20-25%, is a constant feature.

The anemia is due to the lack of production of erythropoietin and the lack of its stimulating effect on erythropoiesis. Therefore, people with chronic renal failurefailure, regardless of the position of dialysis, show a marked improvement in hematocrit during treatment with erythropoietin (epoetin alfa).

Other causes of anemia can include bone marrow suppression effects of uremic toxins, bone marrow fibrosis of blood vessels due to elevated PTH, the toxic effects of aluminum (in antacids, phosphate binder and dialysis solutions) and hemolysis and blood loss associated with dialysis (while the individual is an anticoagulantheparin).

People with chronic renal failure show abnormal hemostasis manifested as high-shock, blood vessels increased reduction surgery, and a high incidence of spontaneous gastrointestinal hemorrhage and cerebrovascular disease (including cerebral hemorrhage and subdural hematoma).

Laboratory abnormalities include prolonged bleeding time, decreased platelet factor III, platelet aggregation and adhesion abnormal prothrombin and the use of altered, none of this iscompletely reversible, even in well-dialyzed individuals. Uremia is associated with high susceptibility to infection, which is considered due to the removal of leukocytes from uremic toxins.

The deletion seems to be greater for neutrophils and lymphoid cells also appear to affect the chemotaxis, the acute inflammatory response, delayed hypersensitivity and the functions of most leukocytes. Acidosis, hyperglycemia, hyperosmolarity and malnutrition are also consideredcontribute to the immunosuppressive therapy, permanent renal failure.

The invasion of dialysis and the use of immunosuppressive drugs in kidney transplant patients also contribute to an increased incidence of infections. CNS signs and symptoms and indicators could range from sleep disorders and mild mental impairment of concentration, poor memory, misjudgments, and neuromuscular irritability (manifested as hiccups, cramps, twitches and spasms) for asterixis, myoclonus,stupor, convulsions and coma in terminal uremia.

Asterixis manifests as involuntary movements seen when the arms are flapping open and grabbed her wrists to "stop the visitors." due to altered E 'of nerve conduction in metabolic encephalopathy wide range of causes, including kidney failure.

Peripheral neuropathy (sensory motor, lower extremities than the upper), exemplified by the Restless Legs Syndrome (feeling sick and poorly localizedinvoluntary movements of limbs), is a common finding continued deterioration in the absence of an important indication for starting dialysis.

Patients undergoing hemodialysis may develop aluminum toxicity, characterized by speech dyspraxia (inability to repeat words), myoclonus, dementia and seizures. Similarly, aggressive acute dialysis can result in a disequilibrium syndrome is characterized by nausea, vomiting, drowsiness, headache, seizures, and within an individual with realityHigh BUN value.

Presumably, this really is an impact of pH or osmolality rapid change in the ECF, resulting in cerebral edema. Nonspecific GI results in uremic patients include anorexia, hiccups, nausea, vomiting, and diverticulosis. Although its exact pathogenesis is unclear, many of the best results with dialysis. Woman with uremia have reduced the amount of estrogen, which may explain the high incidence of amenorrhea and the observation that almost never are able to to end a pregnancy.

regular periods, but higher production rate of pregnancy in general, he took frequent dialysis. Similarly, low levels of testosterone, impotence, oligospermia, and germinal cell dysplasia were common in men with renal continuous no. Finally, continuous renal failure kidney removed as a site of degradation of insulin, which increases the half-life of insulin.

This usually has a stabilizing effect in diabetic patients> Blood sugar was previously difficult to control. Skin changes result from many of the results of continuous renal currently under discussion.

Renal failure patients may still show pallor due to anemia, abnormal skin color related to metabolites accumulated pigmented or gray resulting from hemochromatosis, transfusion-mediated, bruising and hematomas as a result of bleeding disorders, and itching and excoriation resultCa2 + stores secondary hyperparathyroidism. Finally, when urea concentrations are much higher, the evaporation of sweat leaves a residue of urea called "uremic frost."
