Fever, petechiae, and pulmonary infiltrates in an immunocompromised Peruvian man.

The diagnostic considerations raised by immunocompromised patients with opportunistic infection continue to expand. When such patients harbor latent or persistent infection acquired in a tropical environment, the diagnostic challenge is even greater. The Infectious Disease Service at Yale-New Haven Hospital was asked to see a middle-aged man from Peru with known T-cell lymphoma who had recently completed a course of chemotherapy.

Sulfasalazine-induced pulmonary disease.

Sulfasalazine has been widely used in the treatment of inflammatory bowel disease. Although a high incidence of side effects has been reported, pulmonary complications are rare. The clinical, radiographic, and histological abnormalities that occurred in a patient three months after initiation of sulfasalazine are described.

Pulmonary endothelial dysfunction in the presence or absence of interstitial injury induced by intratracheally injected bleomycin in rabbits.

Previously, we reported that repeated subcutaneous administration of bleomycin (BLM) to rabbits produced functional and structural endothelial damage with no evidence of interstitial fibrosis. In the present study, rabbits received intratracheally a single injection of BLM (6 units/kg, n = 6: "low dose" or 11 units/kg, n = 4: "high dose"); 6 additional animals received intratracheally an injection of saline and served as controls. Four weeks after BLM administration, the low-dose group demonstrated significant reduction in the single-pass pulmonary removal of 14C-5-hydroxytryptamine (5-HT) (p less than 0.

Prolonged reduction in serum angiotensin converting enzyme activity after treatment of rabbits with bleomycin.

Clinical and immunologic response to antigen-specific transfer factor in drug-resistant infection with Mycobacterium xenopi.

The administration of transfer factor obtained from three donors who had recovered from clinical infections with Mycobacterium xenopi to a patient who had a destructive pulmonary infection with this organism, was associated with the reversal of an unfavorable clinical course. Cavitary tuberculosis associated with resistance to all combinations of antituberculosis drugs was probably related to a concurrent depression of cell-mediated immunity of unknown origin. Antigen specific but not nonspecific transfer factor caused a rapid and prolonged improvement in both the pulmonary disease and the immunologic deficiency.
