Morphological changes in the kidneys in nonspecific ulcerative colitis were studied and the following variants of the kidney involvement were established: (1) allergic changes manifested by membraneous and mesangio-proliferative glomerulonephritis, renal vasculitis, phenomena of stromal desorganization with lymphoid and histiocyte infiltrations; (2) metabolic changes manifested by various kinds of degeneration of the tubular apparatus including changes typical of potassium-deficient nephropathy; (3) toxic -- necrotic nephrosis and (4) infectious -- nonsuppurative and suppurative interstitial nephritis.

The authors report a case of acute nephritis which appears during a treatment with phenindione. The nephropathy described after this medication are now well known. Their manifestations are either a proteinuria associated or not with a nephrotic syndrome or an interstitial nephritis whose pronostic is reserved. In this observation the mechanism is different : the lesion is glomerular and complicates an allergic vasculitis which was secondary to the phenindione's therapy. The pronostic was good.

A case of fatal viscerotropic Rocky Mountain spotted fever with virtual absence of cutaneous lesions was diagnosed at autopsy by specific immunofluorescent demonstration of Rickettsia rickettsii in spleen, kidney, epididymis and skin. The clinical presentation was that of insidious onset of fever, renal failure, hypotension, hyponatremia and obtundation over a 10 day period. The patient had respiratory insufficiency, hypocalcemia, increases in creatinine phosphokinase (CPK), serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), lactic dehydrogenase (LDH), alkaline phosphatase, billirubin and serum phosphate, grand mal seizure, myalgia and unremitting shock with death occurring on day 12 of illness. Postmortem examination revealed severe vasculitis with interstitial nephritis and multifocal tubular necrosis, pericholangitis with bile stasis, glial nodules in the brain, multifocal rhabdomyonecrosis, interstitial pneumonitis and mild interstitial myocarditis. Risk factors which this patient shared with other patients with fatal Rocky Mountain spotted fever were failure to recognize a rash, failure to obtain a tick bite history, male sex, black race and age greater than 30 years.

Review of clinical and pathologic data from ten fatal cases of Rocky Mountain spotted fever (RMSF) revealed the importance of acute renal failure in the clinical course and of multifocal perivascular interstitial nephritis as the principal pathologic lesion. In nine cases, Rickettsia rickettsii were demonstrated by immunofluorescence in the areas of vasculitis. Evidence was lacking for the role of disseminated intravascular coagulation, glomerulonephritis, or myoglobinuria in the pathogenesis of acute renal failure in these cases. Rickettsia-induced vascular injury led to acute renal failure by several mechanisms. Hypovolemia early in the course resulted in reversible, prerenal azotemia. Transient hypotension in midcourse produced acute tubular necrosis. In fulminant cases, preterminal circulatory collapse was associated with coma and oliguria. The interstitial nephritis could not be demonstrated conclusively to contribute to the acute renal failure.

Acute toxic nephropathy may be produced by a variety of poisons and drugs. Cellular poisons, such as mercuric bichloride, produce tubular necrosis. Many drugs induce an immunologically mediated response presenting as interstitial nephritis, glomerulonephritis or angiitis. Substances, which are not primarily nephrotoxic but induce dehydration, shock, hemolysis, rhabdomyolysis and/or electrolyte disturbances may also lead to secondary acute renal failure. Reduced renal blood flow, suppressed glomerular filtration, increased tubular pressure due to obstruction, and tubular leakage are responsible for the functional breakdown. In addition, specific tubular functions may be impaired. Complete or incomplete recovery is the rule.

Out of 152 cases of Acute renal failure (ARF) 32 patients (21%) were subjected to kidney biopsy. All patients had intrinsic ARF. Prerenal azotemia and obstructive uropathy were excluded. Histologic observations were: Crescentric glomerulonephritis in 7 (21.9%), acute endocapillary proliferative glomerulonephritis 5 (15.6%), acute interstitial nephritis 7 (21.9%), necrotizing vasculitis 4 (12.5%), acute tubular necrosis in 5 (15.6%) and membrano-proliferative GN with superimposed crescent in 2 (6.2%) while renal cortical necrosis was seen in 6.2% of cases. Prebiopsy diagnosis was correct in only 10 (31.25%) cases. The result of biopsy had altered clinical diagnosis in 22 (68.75%) patients and precise renal biopsy diagnosis resulted in therapeutic changes in 54.8% of patients with ARF.

A 17-year old-male presented with a 6-week history of weight loss, lassitude and calf pains. On examination he was very pale. Laboratory tests showed a very high erythrocyte sedimentation rate (155 mm in the first hour), anaemia (haemoglobin 10.1 g/dl), and a raised serum creatinine of 1.54 mg/dl. Microhaematuria (5-10 erythrocytes/microliter) and pronounced pyuria (500 leucocytes/microliter) were present, but the urine was sterile and there was no increase in albumin excretion. The serum IgG was raised to 75.7 g/l, suggesting an autoimmune disorder. Anti-nuclear antibodies (titre 1 : 1920) and anti-double-stranded DNA antibodies (31 U/ml) were present, while the serum complement C4 was decreased to 0.11 g/l. Renal histology showed an interstitial nephritis without glomerular involvement, while the bone marrow showed vasculitis accompanied by a prominent plasma-cell infiltrate. A diagnosis of interstitial nephritis associated with systemic lupus erythematosus was made, with asymptomatic cardiac and hepatic involvement. Renal function recovered rapidly with prednisolone therapy (initial dose 2 mg/kg.d). While glomerulonephritis is the most common lupus-associated renal disorder, isolated interstitial nephritis may occur in some cases, often with an absence of proteinuria.

Extraglomerular renal lesions were studied by light and electron microscopy in 13 farmed mink which showed cataractous eyes associated with spontaneous encephalitozoonosis. The extraglomerular renal lesions consisted of multiple renal cysts, multifocal-to-coalescing interstitial nephritis and vasculitis. Tubular cysts of varying size were present in the corticomedullary junction and medulla. The inflammatory infiltrates were composed mostly of lymphocytes and plasma cells and usually accompanied an interstitial fibrosis. Vasculitis, perivasculitis and sclerotic arteries were frequently seen.

A 58-year-old female patient admitted to hospital for advanced renal failure had a 40 years' history of Crohn's disease and had undergone ileocecal resection. Nevertheless, chronic diarrhea persisted. Subsequently calcium oxalate stones in the urine were repeatedly observed. Progressive renal failure developed. The investigation of the patient showed severe steatorrhea and pronounced hyperoxaluria, and renal biopsy showed severe chronic interstitial nephritis with calcium oxalate crystals. The skin biopsy revealed severe calcium oxalate vasculitis. The pathophysiology and therapy of secondary hyperoxaluria due to small bowel resection are discussed.

We have conducted an immunocytochemical analysis to investigate the presence of the recently described vascular cell adhesion molecule-1 (VCAM-1) in human kidney, using the anti-VCAM-1 monoclonal antibody 1.4C3. In normal control tissue VCAM-1 was present on some (but not all) parietal epithelial cells lining Bowman's capsule. Forty-nine of fifty clinical biopsy specimens were characterised by the additional presence of VCAM-1 on proximal tubular cells. This was most marked in biopsies of patients with interstitial nephritis or systemic vasculitis with crescentic nephritis, but was also observed in biopsies with minimal change, IgA or lupus nephropathy, or from patients with diabetic nephropathy, amyloid, or gout. Proximal tubule VCAM-1 correlated significantly with the number of transferrin-receptor-positive leukocytes (r = 0.607, p less than 0.0001) in the interstitium, but not with expression of HLA-DR by tubular cells. Surprisingly, VCAM-1 was not observed on vascular endothelial cells in these biopsies, even in the presence of a marked infiltrate; this contrasts with other tissues (e.g. skin and synovium). The presence of VCAM-1 on tubular cells in the inflamed kidney indicates the potential for these cells to interact with mononuclear cells, either as accessory cells or as cytotoxic targets. The unexpected absence of VCAM-1 in renal vascular endothelial cells suggests local differences in the endothelial cells of this organ.
