[Nephrotic syndrome complicating treatment with interferon alpha].

UNLABELLED: We report two cases of nephrotic syndrome with minimal glomerular change complicating alpha-interferon therapy. CASE REPORTS: The first patient was a 60-year-old man with Waldenström's disease who was given 1 million units of alpha-interferon three times a week for 22 months. Acute renal failure developed when a second protocol was started. Renal biopsy revealed intraglomerular deposits and no cellular proliferation. Total remission could not be achieved with corticosteroids. The second case was a 46-year-old man given high dose alpha-interferon (15 million units 3 times a week) for lymph node metastasis of a malignant melanoma. A nephrotic syndrome without renal failure developed during the third month of treatment. Minimal glomerular involvement was seen. Symptomatic treatment led to resolution of the nephrotic syndrome. DISCUSSION: Nine other cases of nephrotic syndrome complicating alpha-interferon therapy have been reported in the literature.

[Acute interstitial nephropathy induced by vancomycin].

The authors report a case of tubulo-interstitial nephritis with acute renal failure due to vancomycin used to treat a patient with enterococcus endocarditis. Rechallenge with vancomycin several days after stopping the drug resulted in the appearance of a maculopapular rash and rapid onset of acute oligo-anuric renal failure. Renal biopsy revealed acute interstitial nephritis. This feature is suggestive of cellular mediated hypersensitivity.

Delayed onset of uveitis in TINU syndrome.

We report here the clinical features and outcomes of two patients who presented idiopathic tubulo-interstitial nephritis and uveitis syndrome (TINU syndrome) with ocular disease following the onset of nephropathy. The initial symptoms were renal impairment with asthenia, anorexia and weight loss. An increase in urinary beta2-microglobulin was noticed at the initial checkup in both patients. Renal biopsies showed interstitial cellular infiltration without granulomas or tubular atrophy. No glomerular and vascular alterations were seen and immunofluorescent staining was uniformly negative. Systemic steroid therapy was given and renal function returned to normal within three months. Anterior uveitis occurred in both patients eight months later and responded well to local steroid therapy. Renal involvement in TINU syndrome mostly has a favorable outcome. Despite the possibility of spontaneous regression, systemic steroids may be beneficial in reducing the development of interstitial fibrosis.
