Renal Insufficiency


a syndrome in which all kidney functions are impaired; it results in disturbance of water, electrolyte, and nitrogen metabolism.

Renal insufficiency may be acute or chronic. Acute renal insufficiency may be caused by shock resulting from trauma, burns, blood transfusions, or surgery. It may also be caused by the effect of such poisons as mercury or arsenic on the kidneys; by mushroom poisoning, drugs, infections, and such acute renal diseases as nephritis and pyelonephritis; and by obstruction of the upper urinary tract. The principal symptoms are oliguria or anuria (daily quantity of urine less than 400–500 ml), retention of nitrogenous residues in the body, disturbance of the fluid and acid-base balances, cardiovascular disorders, and anemia. Most of the changes that occur in the kidneys are reversible and diuresis is restored within two weeks, less commonly in one to two months. Treatment is aimed at eliminating such causes as shock and poisoning and at eliminating the metabolic disturbances. Hemodialysis and other means of extrarenal cleansing of blood are used to prevent and control uremia. Recovery with restoration of ability to work takes place within three to 12 months.

Chronic renal insufficiency may result from such kidney diseases as chronic diffuse glomerulonephritis, chronic pyelonephritis, and renal amyloidosis. It may also result from such dynamic or mechanical obstructions of the urinary tract as nephrolithiasis and urethrostenosis, from cardiovascular and collagen diseases, and from such endocrine disorders as diabetes mellitus. Chronicrenal insufficiency is accompanied by general weakness, insomnia, pruritus, dyspepsia, anemia, high and stable hypertension, electrolyte disturbances and, at a later stage, by polyuria giving way to oliguria. It is also accompanied by polyneuritis and by azotemia and uremia.

Treatment in the initial stage consists of a low-protein diet with restricted sodium intake and administration of hypotensive agents in the case of hypertension and of anabolic hormones, cardiac stimulants, and other drugs. At a later stage, when there is an increase in canalicular insufficiency as well, the diet is less restricted and additional measures are taken to maintain the blood’s electrolytic balance. Chronic hemodialysis and kidney transplants are used in the terminal stage of chronic renal insufficiency.

Novel erythropoiesis stimulating protein (NESP) administered subcutaneously corrects anemia in subjects with chronic renal insufficiency (CRI) when administered at a reduced dose frequency compared with recombinant-human erythropoietin (r-HuEPO) (Abstract).
Moreover, there is also little evidence of occurrence of anemia in diabetes without renal insufficiency. Hence, to find out the association of anemia with and without renal impairment, and its correlation with HbA1c, the present study had undertaken.
Conclusion: ACEIs and [beta]-blockers were barely employed to treat elderly CHF patients complicated with renal insufficiency, but diuretics and spironolactone were frequently utilized.
In our case, the potassium level rose to 5.6 mEq/L when the patient (with type III renal insufficiency) was on carvedilol 12.5 mg bid but it normalized (though at the upper limit of normal--5 mEq/L) when the dose of carvedilol was reduced to 6.25 mg bid.
Recent evidence has suggested that mild renal insufficiency is also associated with all-cause and cardiovascular mortality [4, 6].
Metformin Associated Lactic Acidaemia (MALA) is one of the most dangerous side effects of Metformin observed in patients with renal insufficiency, and is a life threatening condition.
Renal insufficiency was explained by 5 stages of chronic kidney disease by estimated GFR based on serum creatinine using Schwartz formula [5].
The purpose of this study was to produce a rat model with functional and histopathological signs of renal insufficiency. After testing some situations in a pilot study, it was possible to standardize a procedure that allowed the establishment of renal failure that could lead the animal to simulate a chronic renal disease with loss of its glomerular filtration capacity.
