Two severe cases of green pit viper bites were reported. The clinical manifestations were severe bleeding and diarrhea. The first patient had acute renal failure complicated from severe diarrhea and hypovolemia. Hematological findings showed hypofibrinogenemia and thrombocytopenia. Renal biopsy performed in the first case showed a picture compatible with that of the recovery phase of acute tubular necrosis. Green pit viper antivenine serum together with symptomatic and supportive treatment was given. Both patients recovered uneventfully.

We describe four female patients with psoriasis treated with fumaric acid esters. In two patients acute renal failure developed during this therapy. Histological investigation of renal biopsy in one patient was compatible with the diagnosis of acute tubular necrosis; her renal function was reversible after cessation of the medication. The histological diagnosis of the other patient was tubulo-interstitial nephritis, possibly as a reaction to acute tubular necrosis. The recovery of her renal function was incomplete after 9 months.

We used fine-needle intrarenal manometry as a guide for detection of acute rejection superimposed on protracted oliguric acute tubular necrosis occurring in the postoperative course of human renal transplantation. We followed intrarenal pressure (IRP) in 31 patients who received 32 renal transplants, 12 from living related donors and 20 from cadaveric donors. There were 19 rejection episodes and 10 episodes of transient cyclosporin A (CyA) nephrotoxicity. Nine patients had posttransplant acute renal failure. Levels of IRP (mmHg) in acute rejection were (mean +/- SD) 48.6 +/- 11.1, significantly higher (p less than 0.001) than the levels in CyA nephrotoxicity (28.2 +/- 5.21), acute tubular necrosis (24.5 +/- 5.5) and normal functioning grafts (26.4 +/- 6.63). Antirejection treatment was associated with return to normal of IRP after 10 days. Intrarenal manometry was performed routinely ever 2-3 days in patients who had postoperative acute renal failure. Increments in IRP were detected on the 7-10th postoperative day in 7 patients who had 10-25 days of post-transplant oliguria. Renal biopsy findings were compatible with acute rejection, and the patients responded to intravenous bolus of steroids. We suggest that fine-needle intrarenal manometry is a reliable test for the detection of acute rejection in circumstances when traditional parameters of altered renal function cannot be evaluated.

Three healthy adult males developed acute renal failure following cocaine abuse. Muscle pain, tenderness, elevated levels of serum muscle enzymes, heme-positive urine and the presence of pigmented granular casts in urine all indicated occurrence of rhabdomyolysis. One of them developed acute compartmental syndrome of the left leg and required emergency fasciotomy. The course of renal failure and fast recovery were suggestive of acute tubular necrosis in all 3 patients. A possible role of cocaine in the aggravation of renal and/or muscle ischemia has been speculated.

1. The effect of the methylxanthine aminophylline on cisplatin (5 mg kg-1 i.v.)-induced acute renal failure was investigated in the rat. Renal function was measured 5 days after cisplatin administration. 2. Cisplatin caused a polyuric acute renal failure. The creatinine clearance was significantly reduced. 3. Aminophylline (24 mg kg-1 12h-1) ameliorated the cisplatin nephrotoxicity when administered during the maintenance phase of acute tubular necrosis. However, it had no effect when only administered prophylactically before the cisplatin application. 4. Enprofylline (20 mg kg-1 4h-1 with dose adjustment), a methylxanthine lacking adenosine receptor antagonism in comparison to aminophylline, had no protective effect on cisplatin nephrotoxicity. 5. Adenosine is a renal vasoconstrictor and decreases glomerular filtration rate. Endogenous adenosine in the kidney is formed by degradation of ATP and is thought to be involved in various forms of acute renal failure. The results suggest that adenosine may be involved in the haemodynamic changes in the kidney induced by cisplatin.

We describe two patients who developed acute renal failure during therapy with fumaric acid-esters. Histologic findings after renal biopsy in one patient were compatible with the diagnosis of acute tubular necrosis (ATN), and renal function was restored after cessation of the medication. The histologic diagnosis in the other patient was tubulo-interstitial nephritis (TIN), possibly reactive to ATN. The recovery of renal function was incomplete after 9 months. Two other patients had deterioration of renal function and proteinuria during therapy with fumaric acid-esters. The symptoms were completely reversible in one patient after discontinuation of the medication, and incompletely reversible in the other. The literature is reviewed and a comparison is drawn with the maleic acid model in the rat.

The effects of intramuscular glycerol on ischemic acute renal failure was investigated in dogs. Anesthetized dogs received a bilateral 120-min renal artery obstruction (RAO) alone, RAO plus 5 ml/kg of 50% glycerol or RAO plus 5 ml/kg of 75% glycerol. Control groups received the glycerol injection, but not RAO. Renal histopathology was minimal in dogs receiving glycerol alone. In RAO dogs, those receiving 50% glycerol showed diffuse acute tubular necrosis (ATN), while those receiving 75% glycerol had severe ATN with extreme mortality. Changes in serum creatinine, creatinine clearance, and fractional excretion of sodium were consistent with the histopathologic changes. We conclude that myoglobinuria, of a degree insufficient to cause renal failure itself, can interact with renal ischemia to significantly exacerbate the renal damage produced.

At the Mubarak Al-Kabeer University Hospital of Kuwait (Arabian Gulf), 77 episodes of acute renal failure were collected prospectively over 2 years, yielding a mean annual incidence rate of 9.5/100,000 population. Forty-four episodes occurred in hospital, a rate of 1.3 per 1000 admissions. In this group, acute tubular necrosis was the commonest cause (27 episodes). Thirty-three episodes occurred in the community, acute tubular necrosis accounting for 11 episodes. In contrast to hospital-acquired renal failure there was a tendency for increased incidence of community-acquired renal failure in the summer months. A more striking observation was the lower mortality in the community-acquired form. The mortality was not related to severity of renal failure even within the group with acute tubular necrosis.

The results obtained by MR tomography in 30 patients after renal grafting are compared with the clinical and histological data in respect of corticomedullary contrast (CMC). In 22 patients with regular functioning of the transplant the CMC was normal at 19.4%. Eight MR examinations yielded a clearly reduced CMC below 14%. In 7 of these 8 patients it was possible to prove histologically the existence of an acute tubular necrosis or of a transplant rejection. Noninvasive MR tomography yielded an early indication for treating the acute renal transplant rejection without being able to differentiate between such a rejection and acute renal failure.

In 3 years seventeen patients presented to one unit with renal failure associated with the use of non-steroidal anti-inflammatory drugs (NSAID). Seven patients presented with acute renal failure, in four due to acute tubular necrosis and in three to acute interstitial nephritis; all recovered when NSAID treatment was stopped. Four patients presented with symptomless renal impairment discovered during routine follow-up in a rheumatology clinic; again all improved on withdrawal of NSAID. The remaining six patients presented with chronic renal failure, a disorder not previously associated with NSAID treatment. The pattern of renal disease associated with NSAID may be more extensive than has previously been recognised. A history of NSAID use should be sought in all patients presenting with unexplained renal failure.
