Tubulointerstitial and glomerular nephritis associated with rifampin. Report of a case.

In a patient with tuberculosis and acute renal failure related to administration of therapeutic rifampin, treatment was discontinued for five weeks. It was reinstituted three weeks later. Unlike other patients previously described, the expected adverse renal reaction occurred only gradually and without symptoms, although tubular and glomerular disease developed. Also unique was a striking deposition of immunoglobulin about the tubules. This finding, in association with interstitial nephritis and tubular glycosuria, is similar to an experimental autologous renal disease mediated by antibody to tubular basement membrane.

Tension pleural effusion. A delayed complication of pneumothorax therapy in tuberculosis.

Three cases of delayed development of pleural effusion under tension, 20 to 30 years after therapeutic pneumothorax, are described. A sudden increase in dyspnea and the radiographic findings of increasing opacity, a change from hypovolemia to hypervolemia of the hemithorax, and mediastinal shift should alert one to this delayed complication. Careful thoracentesis to decompress intrapleural tension effusion can relieve the dyspnea and improve hypoxemia. The potential risks of creating excessive negative intrapleural pressure are presented.

Theophylline-induced seizures in adults. Correlation with serum concentrations.

Eight patients developed grand mal seizures during intravenous theophylline therapy. None had a history of neurologic disorder, and all were acutely ill with severe pulmonary or cardiovascular disease, or both. Serum theophylline concentrations obtained within 1 hour of the seizure ranged from 25 mug/ml to 70mug/ml, with a mean value (53 plus or minus 4.8 mug/ml) more than twice the upper limit of the recommended therapeutic concentration. This serum theophylline concentration was greater than the concentration found in a group of patients with less severe drug-related symptoms (35 plus or minus 1.8 mug/ml, P less than 0.01). A third group of patients without drug-related symptoms had a mean theophylline serum concentration of 19 plus or minus 2.0 mug/ml, which was less than that found in either group with toxicity symptoms (P less than 0.05). Factors predisposing to the high serum concentrations in the patients with seizures were both higher drug dosage, compared with the other groups (P less than 0.01), and hepatic dysfunction, which was more common in both groups with drug-related symptoms.
