Renal failure
-
To describe long-term quality of life, intensive care, and hospital mortality in patients with acute renal and respiratory failure treated with one of two methods of renal replacement therapy (RRT). ⋯ (1) The method of RRT used in ICU patients with ARF had no influence on survival; (2) The long-term survivors of multi-organ failure have poor physical health.

Comparative Study
Heparin-induced thrombocytopenia in patients administered heparin solely for hemodialysis.
Heparin, universally used in patients on dialysis, is the cause for immune-mediated heparin-induced thrombocytopenia (HIT). ⋯ HIT can occur in patients administered heparin solely for hemodialysis. When HIT is suspected, heparin should be discontinued and an alternative anticoagulation initiated. Argatroban, which is not renally cleared, supports continued renal replacement therapy in HIT patients.

The provision and maintenance of vascular access remains a major cost to end-stage renal failure programs. In addition, vascular access occlusion, results in significant morbidity in hemodialysis patients. Age, gender, diabetes mellitus, malignancy, smoking habits, administration of heparin per hemodialysis session, previous dialysis catheter insertion, number of hemodialysis sessions and location of the fistula may be associated with survival of the primary arteriovenous fistula. We examined the effects of various factors on fistulas in 412 chronic renal insufficiency patients. ⋯ While primary arteriovenous fistula patency was shortened in chronic renal insufficiency patients with diabetes mellitus, presence of malignancy, and previous catheter insertion, patency was longer in patients with heparin used for hemodialysis and hemodialysis count per week (> or =3).

Identification of factors causing acute renal failure (ARF) and its associated poor prognosis in critically ill patients can help in planning strategies to prevent ARF and to prioritize the utilization of sparse and expensive therapeutic modalities. Most of the studies in such patients have been done in the developed world, and similar data from the developing world is sparse. We analyzed 45 consecutive patients who developed ARF in the intensive care unit (ICU) during a 12-month period. ⋯ On comparing the predictor outcomes between survivors and nonsurvivors by multivariate analysis, only the number of failed organs at the time of ARF (2.6 +/- 0.9 vs. 4.5 +/- 0.8) and serum albumin < 3.0 g/dL were found to be statistically significant. To conclude, ARF in critically ill patients is multifactorial in origin and carries a high mortality. Mortality in these patients increases with increasing numbers of failed organs and with a serum albumin of < 3.0 g/dL.

Tubulointerstitial injury is both a key feature of diabetic nephropathy and an important predictor of renal dysfunction. N-Acetyl B glucosaminidase (NAG) is derived from proximal tubular cells and is widely used to evaluate tubular renal function. ⋯ Urinary NAG excretion is elevated in type II diabetic patients as compared with the healthy individuals. Perindopril/indapamide administration is effective in reducing urinary NAG excretion in these patients, and this effect seems to be independent from blood pressure and glycemia control. Presence of tubular proteinuria may be an early indicator of diabetic renal disease in patients without microalbuminuria. Perindopril (2 mg)/ indapamide (0.625 mg)/o.d. treatment may have beneficial effect on the tubulointerstitial damage in diabetic kidney disease.
