Anti-tubular basement membrane antibodies were determined by ELISA in 217 patients with different renal diseases. The assay for antibodies in serum was based on a 58 kD bovine tubular basement membrane antigen. Sera were studied from 69 patients with different forms of interstitial nephritis; 15 patients (10 women, 5 men) had anti-tubular basement membrane titers above the normal (compared with a reference group of healthy blood donors). Three patients are presented in greater detail. Thirty-four patients with pyelonephritis (confirmed by intravenous urogram) were investigated; one serum was positive. Sera from 114 patients with renal glomerular and/or vascular disease were studied; 12 had positive titers for tubular basement membrane and glomerular basement membrane or other kidney disease antibodies. This study supports the opinion that damage in the renal medulla can be caused by an autoimmune process. Circulating anti-TBM antibodies may be of value in the investigation of patients with tubulo-interstitial diseases but the cause and prognosis of this condition is, however, not known.

We describe a case, seemingly sporadic, in which ocular and acral malformations were associated with an interstitial nephropathy; we made a diagnosis of acro-renal-ocular syndrome. There was no stasis, reflux, or urinary tract infection in our patient. We believe that interstitial nephritis in acro-renal-ocular syndrome may not always be pyelonephritis, as previously reported.

In a series of 2028 patients with chronic renal failure, the diseases leading to renal failure, the presence or absence of reversible factors and their nature, and the rate of decline of renal function of the most common conditions have been described and analysed. Seven diseases: chronic interstitial nephritis (27.85%), diabetic nephropathy (26.76%), chronic glomerulonephritis (18.20%), benign nephrosclerosis (10.06%), chronic pyelonephritis (7.29%), focal glomerulosclerosis (3.20%), and autosomal dominant polycystic disease of the kidneys (2.07%), accounted for 95.43% of all the patients. These diseases were studied in greater detail and the results are presented here. It was found that there was a great variation in the rate of decline of renal function in the different groups, with chronic glomerulonephritis and focal glomerular sclerosis progressing most rapidly, diabetic nephropathy slightly slower, and the others at a less alarming pace. However, once serum creatinine had reached 177 mumol/l there was an inexorable decline in renal function and the end stage was reached in almost all patients.

We describe an unusual complication of acute pyelonephritis in a 45-year-old diabetic female. She was admitted to our hospital due to fever and flank pain which had developed 10 days earlier. Urinalysis showed many WBC and urine culture revealed Escherichia coli. After adequate antibiotic treatment, clinical symptoms abated but renal failure and leukocyturia persisted. Abdominal CT showed bilateral focal bacterial nephritis and renal biopsy disclosed chronic granulomatous interstitial nephritis. On the 80th hospital day she was discharged with a serum creatinine of 299 mumol/l. In the outpatient clinic, renal dysfunction and leukocyturia persisted up to 1 year. In conclusion, this case raises the possibility of a chronic interstitial process of acute pyelonephritis.

An 8-year-old spayed female ferret was examined for diffuse generalized alopecia, erythema, erosions, crusts, and ulcerated plaques that were nonresponsive to long-term administration of corticosteroids. Cutaneous epitheliotropic lymphoma was diagnosed on the basis of histologic examination of skin biopsy specimens. Neoplastic cells were determined to be of T-lymphocytic origin by results of immunohistochemical staining with a rabbit anti-CD3 monoclonal antibody. Additional laboratory abnormalities detected included anemia, azotemia, isosthenuria, pyuria, and bacteriuria. Treatment included isotretinoin and amoxicillin trihydrate plus clavulanate potassium administered orally, and oatmeal-based shampoos. Isotretinoin was tolerated well and cutaneous lesions resolved after 60 days of treatment, but pretreatment azotemia worsened and the ferret was euthanatized. Necropsy revealed cutaneous epitheliotropic lymphoma, pyelonephritis, and interstitial nephritis. Renal disease most likely was caused by immunosuppression secondary to chronic treatment with corticosteroids and aging. Isotretinoin, although not curative, may be useful for the palliative treatment of cutaneous epitheliotropic lymphoma in ferrets.

Post-transplant neutrophilic interstitial nephritis (NIN) is characterized by an interstitial infiltrate consisting of polymorphonuclear cells that leads frequently to acute graft dysfunction. In 220 graft biopsies performed because of renal dysfunction over 2 years in our unit, 11 (5%) diagnoses of NIN were made. Only two patients had chronic pyelonephritis as original disease. Four patients had urological problems before transplantation. After transplantation, five patients had urinary tract infection, one had urethral stenosis, two had vesicourethral reflux and one patient had a perinephritic abscess. Seven patients had fever (63%). Only in six patients did urine culture lead to microorganism isolation. After 6 months, only two patients had a serum creatinine level < 1.4 mg/dl, five patients had abnormal function, three had lost their grafts, and one patient had died with sepsis. We conclude that 5% of the biopsies performed in our center disclosed NIN, an entity that causes graft dysfunction and progresses frequently to chronic renal failure. In some cases, no infectious etiology could be detected.

The renal lesions are of special importance in the captive primates. The most commonly pathologies are: pyelonephritis, nephrocalcinosis, glomerulonephritis, congenital malformations, hydronephrosis and functional diseases. We report the histopathological study of renal lesions of five cases of deaths in Cebus apella (Primates) of the Argentinean Primate Center. The ages of the monkeys were from 4 months to 15 years old. Microscopically, we have observed principally acute diffuse proliferative glomerulonephritis, hilar mesangio proliferative glomerulonephritis, extracapilar glomerulonephritis with crescents, chronic interstitial nephritis and chronic pyelophritis.

Acute renal insufficiency (ARI) complicated the course of the underlying process, including primary and secondary glomerulonephritis, interstitial nephritis, pyelonephritis, dysmetabolic nephropathies, urolithiasis, tubulopathies, renal congenitae defects and injuries in 136 of 1695 children with nephrological diseases hospitalized at Republican Pediatric Renal Center during the last decade. In 69.1% cases ARI developed by the renal type, in 23.5% cases was caused by prerenal factors, and rarely (in 7.4% cases) by postrenal factors. Renal ARI in children was caused by 5 causes, including glomerulonephritis (47%), acute tubular necrosis (19%), interstitial nephritis (14%), vascular disorders (11%) resultant from vasculitis, renal vein thrombosis, and acute crystalluria (9%) which developed in the presence of grave dysmetabolic nephropathy. Among three clinical variants of ARI the most severe was observed in renal ARI leading to grave endogenous intoxication and pronounced decompensation of renal function. More benign course of renal ARI caused by acute tubular necrosis or acute crystalluria differed significantly from prerenal ARI by a more pronounced endogenous intoxication, increased fractionated sodium excretion, and renal insufficiency index higher than 1.

Diuretic and aciduretic reactions were compared in healthy children and children with various renal diseases using furosemide loading test. Diuresis, urinary pH, urinary excretion of titered acids and ammonium, and ammonium coefficient were evaluated in healthy controls, patients with chronic and acute renal insufficiency, convalescents after acute renal insufficiency and acute postinfection glomerulonephritis, patients with chronic pyelonephritis, interstitial nephritis, lipoid nephrosis, hematuric chronic glomerulonephritis, and patients with a solitary kidney. Diuresis, urinary pH, ammonium excretion, and ammonium coefficient are proposed as the main test parameters. Patients with the distal tubular acidosis syndrome formed a special group by the results of urinary pH measurements during the third hour of furosemide action. The test helps evaluate the severity of disease and predict its course.

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.
