Percutaneous needle biopsy of the kidney on eight nephrotic patients with Schistosoma mansoni and chronic Salmonella paratyphi A infection showed diffuse proliferative glomerular change in all biopsies. Capillary basement membrane was normal. Diffuse granular deposits were detected in the glomerular mesangial cells by direct staining with fluorescein labelled anti-IgG anti-IgM. No fluorescence was obtained with rabbit anti-Salmonella paratyphi A. After treatment with ampicillin and niridazole, a reduction of cellular proliferation and mesangial matrix expansion was observed. Simultaneously following treatment there occurred a dramatic clinical improvement with cessation of proteinuria and a return of plasma protein levels and serum complement (C3) to normal values.

This paper reports on a 26 year old male who died of toxic diphtheria with all typical features such as: Bullneck, paralysis of the soft palate, renal failure accompanied by proteinuria and--most notably--myocarditis (very typical microscopically) with circulatory disturbances and finally left and right hand failure. The myocarditis hat caused increases of SGOT, SGPT, CPK, LDH and HBDH to values not seen before by us in the course of myocarditis. The patient had been immunized against diphtheria as a child. Initial treatment consisted of the application of ampicillin which caused rapid regression of the local symptoms in the pharyngeal region including the bullneck-symptom; of course the course of intoxication was not influenced, even after the patient had been admitted to the hospital, the disease correctly diagnosed and antitoxin given three days before death.

Borrelia burgdorferi infection was diagnosed serologically in a dog with lethargy, stiffness, and anorexia. Treatment with ampicillin and chloramphenicol did not alleviate the signs. Azotemia, proteinuria, cylindruria, pyuria, and hematuria developed over a 3-month period. Antibody titer for B burgdorferi remained high (1:8,192) during this time. Renal histopathologic findings included severe, chronic, diffuse, membranoproliferative glomerulonephritis and moderate chronic, multifocal, interstitial nephritis. Borrelia burgdorferi organisms were identified in renal tissue and in urine by results of immunofluorescent studies and bacteriologic culture, respectively.

Antibiotics are the principal cause of drug-associated nephropathy. They are responsible for acute interstitial nephropathy (AIN) or acute tubulo-interstitial nephropathy (ATIN) due to two different pathophysiologic mechanisms: a drug-induced immunologic process and direct action due to drug accumulation. 1) Ain of immunologic origin. These are rare and are induced either by beta-lactamines or by rifampicin. Among the beta-lactamines, methicillin is the most often responsible, while penicillin and ampicillin are less often, and only rarely are carbenicillin, oxacillin, nafcillin, cephalothin and cephalexin. Macroscopic hematuria occurring 10 to 15 days after initiation of treatment usually reveals the renal involvement. It is associated with or preceded by fever, skin eruption and blood eosinophilia. Renal insufficiency (RI) is not severe and rarely requires hemodialysis (HD). The course is usually favorable. Rifampicin-induced AIN is observed in two circumstances, either during intermittent treatment or when previous treatment is resumed. Macroscopic hematuria is rare and RI often severe. Anti-rifampicin anti-bodies are usually found. 2) ATIN due to direct toxicity. Several classes of antibiotics may be responsible: cephalosporins, polymyxins or cyclins, but it is usually observed with aminoglycosides (AG). The incidence of renal involvement due to the latter group is estimated to be 4 to 10%. Nephrotoxicity is initially reflected by polyuria, tubular proteinuria and increased enzymuria, followed by cylindruria and reduced glomerular filtration. HD is rarely required. The proximal tubule is predominantly affected; pathological findings are disappearance of the brush border and tubular necrosis. Electronic microscopy shows lysosomal alterations with numerous myelinic bodies. Tubular regeneration occurs within 15 to 30 days.(ABSTRACT TRUNCATED AT 250 WORDS)

Nine episodes of drug associated acute interstitial nephritis, in seven patients, were treated between 1972 and 1980. The drugs implicated were cotrimoxazole (three times), ampicillin, Magnapen (ampicillin and flucloxacillin), penicillin, gentamicin, paracetamol and bendrofluazide. The time from exposure to the onset of symptoms ranged from one to 30 days. Presentation was with acute renal failure, which was non-oliguric in five cases, accompanied by rash (four), fever (four), and loin pain (two). Renal biopsy was carried out in all cases, and showed a characteristic interstitial infiltrate comprising substantial numbers of lymphocytes and plasma cells, with a variable number of neutrophils, eosinophils and histiocytes. Immunofluorescence was negative in all four cases studied in the acute phase, and showed scattered deposits of IgG, IgM, IgA and C3 on the tubular basement membrane in one patient during recovery. Significant proteinuria and an abnormal urine deposit were present in all cases, and seven of nine had radiological evidence of enlarged kidneys. Seven episodes were treated with high doses of methyl prednisolone and in all there was a response with a diuresis or spontaneous fall in serum creatinine within 72 hrs, and recovery of virtually normal renal function. Of two cases who did not initially receive steroids, one improved more slowly and one developed chronic renal impairment.

Neonates, especially preterms, are known to have low glomerular filtration rates (GFR). This may result in elevated trough concentrations during multiple administration of aminoglycosides (AGs), potentially leading to nephro- and ototoxic reactions. The once-daily administration (q.d.) of AGs has been shown to be equally or better tolerated in adults and children than the conventional schedules (twice daily, b.i.d.; thrice daily, t.i.d.), while offering potential pharmacodynamic and nursing advantages. No data, however, are available for neonates. As a consequence, this pilot study was conducted in order to assess the tolerance of the once-a-day administration of amikacin in comparison with the twice daily dose regimen, in relation to the pharmacokinetics of the drug under these two schedules. 22 Male neonates (gestational age > or = 34 weeks; postnatal age < or = 2 days) were randomized to receive amikacin (AK) (15 mg/kg/day) q.d. (n = 10) or b.i.d. (n = 12) together with ampicillin (50 mg/kg/12 h). AK plasma levels were measured at days 1, 3, 5 and 7 of treatment just before the next dose (trough level) and 1 h after completion of infusion (peak level) and after 3 and 6 h only at day 1. Due to the small size of the samples, no difference in efficacy could be assessed and was not the aim per se. Glomerular dysfunction was assessed by creatinine clearance, and tubular injuries by the urinary excretion of proteins (retinol binding protein, beta 2-microglobulin, clara cell protein (P1) and microalbumin), enzymes (N-acetyl-beta-D-glucosaminidase, alkaline phosphatase, alanine aminopeptidase, and gamma-glutamyltransferase), and total phospholipids (TPL) in urine. Ototoxicity was assessed by brainstem auditory evoked potentials (BAEPs) at days 0, 3 and 9 of therapy. Eight healthy neonates served as controls. All patients showed a normal and similar increase of GFR during the first postnatal days. Proteinuria did not increase, but enzymuria and TPL increased significantly during the treatment in both AK groups without significant difference between groups. BAEPs at day 9 were not significantly different between treated and untreated patients. We conclude from this pilot study that, in the absence of more toxicity, the q.d. administration of AK in neonates of > or = 34 weeks of gestational age may be recommended over its bid schedule in view of its potential advantages.

Staphylococcus aureus is a rare cause of postinfectious glomerulonephritis, and Staphylococcus-related glomerulonephritis primarily occurs in middle-aged or elderly patients. Patients with Staphylococcus-related glomerulonephritis also present with hematuria, proteinuria of varying degrees, rising serum creatinine levels, and/or edema. The severity of renal insufficiency is proportional to the degree of proliferation and crescent formation. Here, we present a diabetic patient admitted with a history of 1 week of left elbow pain. Laboratory results revealed that erythrocyte sedimentation rate was 110 mm/hour, serum creatinine level was 1 mg/dL, C-reactive protein level was 150 mg/L, and magnetic resonance imaging showed signal changes in favor of osteomyelitis at the olecranon level, with diffuse edematous appearance in the elbow skin tissue and increased intra-articular effusion. After diagnosis of osteomyelitis, ampicillin/sulbactam and teicoplanin were administered. After day 7 of admission, the patient developed acute kidney injury requiring hemodialysis under antibiotic treatment. Kidney biopsy was performed to determine the underlying cause, which showed Staphylococcus-related glomerulonephritis. Recovery of renal functions was observed after antibiotic and supportive treatment.

We report a case of a patient who developed dialysis-requiring acute kidney injury (AKI) after the use of canagliflozin. A 66-year-old man with type 2 diabetes who was recovering from left knee septic arthritis at a rehabilitation facility was admitted with oliguric AKI 5 days after starting treatment with canagliflozin, an inhibitor of sodium/glucose cotransporter 2 (SGLT2). The patient presented with hematuria, non-nephrotic-range proteinuria, and serum creatinine level of 6.8 (baseline, 1.1-1.3) mg/dL. There was no recent use of radiocontrast agents or exposure to other nephrotoxins. The patient subsequently required hemodialysis. Due to recent antibiotic use (ampicillin-sulbactam), acute interstitial nephritis was considered in the differential diagnosis. Kidney biopsy was performed, which showed the presence of osmotic nephropathy. The patient's kidney function returned to baseline after 2 weeks of hemodialysis. This case provides evidence of an association of osmotic nephropathy with the use of canagliflozin and discusses potential mechanisms. We recommend kidney biopsy for cases of severe AKI associated with SGLT2 inhibitors to better understand the relationship of this complication with the use of this class of medications.
