Post-rifampicin (RMP) acute renal failure (ARF) is a complication seldom recognized of the antiTB treatment worldwide. The renal failure which occurs especially after intermittent administration of RMP is most frequent due to acute interstitial nephritis by allergic mechanism. In our study we found very few cases of acute tubular necrosis or glomerular lesions revealed by rapidly progressive glomerulo-nephritis or nephrotic syndrome. The renal lesions, accompanied by anuria and usually needing hemodialysis, were associated to auto-immune hemolytic anemia, trombocytopenia, hepatic failure and gastro-intestinal disturbances. The authors review their experience (60 cases), representing about half of the cases published worldwide. The main causes of this high prevalence of post-RMP ARF in Romania are discussed: intermittent twice-a-week RMP treatment, high incidence of TB, lack of compliance to treatment, possible contribution of some by-substances in RMP capsule. We described the clinic, biology and evolution of this dangerous and underestimated entity. We compared our experience with the published data, discussing the etiology and pathogenesis, trying to design the fine portrait of this ailment.

Snakebite induced acute renal failure continues to occur in many tropical areas of the world. Renal histological lesions other than acute tubular necrosis and acute cortical necrosis as the cause of acute renal failure are rare. Only 3 cases of acute interstitial nephritis in patients with snakebite induced acute renal failure have been previously reported. We report a patient with acute renal failure following viperine snakebite due to acute interstitial nephritis. After a prolonged oliguric phase, there was complete recovery of renal function without institution of steroids. Interstitial nephritis may result from a hypersensitivity reaction to some component of the snake venom.

A previously healthy toddler developed severe acute renal failure with nephromegaly and peripheral atypical lymphocytosis. Profound interstitial nephritis with acute tubular necrosis was diagnosed by renal biopsy, and both the clinical picture and serological evaluation suggested Epstein-Barr virus (EBV) as the etiological agent. The previous reports of EBV-induced renal failure and the clinical and pathological presentations of interstitial nephritis in children are reviewed.

Cytomegalovirus is the most important viral infection in kidney transplants, but rarely affects the allograft after the sixth month posttransplantation. We present a patient who developed renal failure eighteen months posttransplant; a kidney biopsy showed cytomegalovirus inclusions, acute tubular necrosis and mild interstitial nephritis. After intravenous ganciclovir, renal function transiently improved. Cytomegalovirus pp65 antigen was weekly reported as negative. One month later another biopsy was performed due to renal failure. The findings were consistent with tubular atrophy and severe interstitial nephritis. No cytomegalovirus cellular inclusions were found on histology, including immunohistochemical and polymerase chain reaction studies; pp65 antigen studies were persistently negative. Despite an attempt to recover renal function with steroid therapy, the patient restarted hemodialysis 20 months posttransplantation. This report suggests that cytomegalovirus should be considered as a late cause of kidney failure even in the absence of infection-related symptoms. The irreversible allograft damage can be caused despite the successful eradication of the virus with intravenous ganciclovir.

In chronic glomerular nephritis (CGN), it is important to estimate the renal function and 24 hr urinary protein excretion to estimate the effectiveness of the treatment. In this study, we evaluated the usefulness of a microscopic urine test in making pathological diagnosis. As a result, we found that IgA nephritis has a significantly higher urinary RBC count among the CGN group, and found focal glomerular sclerosis and membranoproliferatine GN patients have significantly higher urinary RBC count among nephrotic patients. Among patients who have moderate renal insufficiency, acute tubular necrosis and acute interstitial nephritis have higher levels in urinary RBC counting. In summary, we can estimate the pathology of renal diseases by microscopic urinary tests to a certain extent. In western countries, physician have used the Cockcroft and Gault formula to estimate creatinine clearance, and they also have used urine protein-to-creatinine ratio to estimate 24 hr urinary protein excretion. We evaluated these formulae with Japanese, and as a result, found lower estimation of creatinine clearance and urinary protein excretion, which may be due to lower their muscle mass. We need further evaluation to make suitable changes to these formulae for Japanese.

In this study we have analyzed incidence, causes and clinical course of ARF due to primary intrarenal disease other than acute tubular necrosis. Thousand hundred and twenty two cases of ARF of diverse etiology were studied over a period of 16 years; July 1984 to Dec, 1999. Surgical ARF 231 (20.6%) were not included in the present study. Intrinsic renal diseases were responsible for ARF in 891 (79.4%) of cases. The most common intrinsic renal diseases 705 (79.4%) causing ARF were ischemic/toxic acute tubular necrosis, but not included in this study. Acute renal failure was related to acute glomerulonephritis (9.3%), acute interstitial nephritis (7%), and renal cortical necrosis in (4.6%) of cases. Therefore intrinsic renal diseases other than ATN were the causative factor for acute renal failure in 186 (20.8%) patients in our study. Crescentic (51.8%) and endocapillary proliferative glomerulonephritis (34.9%), were the main glomerular diseases responsible for ARF and 75.9% of GN was related to infectious etiology. Fifty three percent of acute interstitial nephritis was drug induced and in 25 (40%) patients it was related to an infectious etiology. Renal cortical necrosis due to HUS was observed in 16 (39%) children and majority (76.47%) of the cases had a diarrhoeal prodrome. Obstetrical complications were the main causes (61%) of cortical necrosis in adults with acute renal failure. Thus, intrinsic renal diseases other than ATN were responsible for ARF in 186 (20.8%) cases. Post-infectious glomerulonephritis, acute interstitial nephritis and renal cortical necrosis (complicating HUS in children and obstetrical complications in adult) are the main causes of acute renal failure in our study. Both acute GN and interstitial nephritis had excellent prognosis, however renal cortical necrosis was associated with a very high mortality.

A 17-year-old healthy girl was admitted to our hospital with diffuse abdominal pain and decreased oral intake of about 11 days duration. About a week prior to admission, she had taken naproxen, 250 mg four times a day for 4 days. Physical examination was normal except for diffuse abdominal tenderness on deep palpation. Investigations revealed high serum BUN (42 mg/dl) and creatinine (4.0 mg/dl). Serum electrolytes and complement (C3, C4) levels and urinalysis were normal. Antinuclear-antibody and anti-dsDNA were negative. Kidney biopsy revealed renal papillary necrosis, acute tubular necrosis, and focal interstitial nephritis. A diagnosis of nonoliguric acute renal failure due to naproxen nephrotoxicity was made. She received intravenous hydration, and oral steroids, which was gradually discontinued in 3 months. A follow-up at 4 months revealed normal renal function with a serum creatinine of 1.1 mg/dl, BUN 7 mg/dl, and normal urinalysis. The report highlights a need for caution while using naproxen or any other nonsteroidal anti-inflammatory drugs, even for a short duration.

Acute renal failure (ARF) is an uncommon but alarming complication of idiopathic nephrotic syndrome. The renal failure could be secondary to causes evident from the history and evaluation, such as severe intravascular volume depletion, acute tubular necrosis, allergic interstitial nephritis, bilateral renal vein thrombosis, acute pyelonephritis, or rapid progression of the original glomerular disease. It may be termed idiopathic if the underlying cause is undetermined. We present three children with idiopathic nephrotic syndrome who were admitted with acute renal failure. One case was due to drug-induced allergic interstitial nephritis. The other two were idiopathic in nature. Improvement in renal function occurred in the three patients over a variable period of 10 days to 4 weeks. After careful exclusion of well-known causes of acute renal failure, idiopathic acute renal failure (IARF) should be considered as a diagnostic possibility in these patients. The exact pathophysiology of IARF is not understood. Possible proposed explanations include interstitial edema, tubular obstruction, altered glomerular permeability, and unrecognized hypovolemia.

Acute renal failure (ARF) is an unusual complication of wasp stings and mostly results from toxic-ischemic acute tubular necrosis. This patient, who was stung by a swarm of wasps, experienced an allergic reaction, rhabdomyolysis, intravascular hemolysis, and subsequent ARF. The originality of this case report is related to the finding of combined lesions of acute tubulointerstitial nephritis and acute tubular nephropathy. From our extensive literature review, it is the first case of a patient developing this type of injury after wasp stings, and the complications have been documented previously only in one form or another. Renal biopsy should be encouraged, especially for a patient with delayed recovery of renal function after wasp stings, to facilitate early steroid treatment for the patient with the histological change of acute interstitial nephritis. Early use of steroid therapy may hasten renal recovery by preventing the development of interstitial fibrosis.

A 24-year-old woman with a history of penicillin allergy developed reversible acute renal failure after receiving cephalexin for 4 days. The patient experienced nausea, vomiting, diarrhea, pruritus, cough, and an elevated creatinine level of 2.2 mg/dl. The patient's creatinine level continued to rise, peaking at 5.3 mg/dl on hospital day 3. Nephrotoxic acute tubular necrosis was confirmed by electron microscopy. Within 1 month of discharge from the hospital, the patient's creatinine level decreased to 0.6 mg/dl. Although the renal injury most commonly associated with the cephalosporin class of antibiotics is allergic interstitial nephritis, currently available cephalosporins infrequently can cause direct tubular toxicity.
