53 HIV-positive patients, 66% of them zidovudine-experienced, were randomized to receive monotherapy with zidovudine or sequential therapy with zidovudine, didanosine and zalcitabine. Clinical end points, CD4 cell count change, and analysis abnormalities showed better results with sequential therapy.
OBJECTIVE: Eighteen patients who were judged to have systemic vasculitis (1990 American College of Reumathology criteria) affecting the kidney, from January 1988 to August 1996, were reviewed. METHOD: We analyzed characteristics of clinical, biochemical, histopathological features, the interval between the onset of the symptoms to a diagnosis of disease, treatment and overall outcome. RESULTS: The principal mode of presentation of the vasculitis is general, renal and pulmonary symptoms. The discovery of ANCA has improved the diagnostic procedure in patients with these diseases. Renal biopsy facilitates early diagnosis, prognosis and treatment. The renal lesion typically shows a segmental necrotizing glomerulonephritis and extracapillary proliferation forming crescent. CONCLUSIONS: The systemic vasculitis with renal involvement carries a poor prognosis and high mortality. A variety of treatment has been employed, but their precise role in the management of these vasculitis is still being elucidated.

OBJECTIVE: The incidence of Pseudomonas aeruginosa in HIV-infected patients has increased over the last years. We describe a case of pseudomonal breast abscess complicated with fatal septicemia in an AIDS patient. CASE REPORT: A 21-year-old woman was admitted for fever, chills, nausea, vomiting and pain in the breast. She had a swelling in the right breast of 3 days duration. HIV infection had been confirmed 6 years earlier. CD4 count was 2/mm3. Surgical drainage produced a blue-green purulent discharge which grew Pseudomonas aeruginosa on culture. Despite cloxacilin, then ceftazidime and amikacin, initial improvement was followed 2 weeks later by nodular pulmonary infiltration with cavitation. P. aeruginosa was recovered from sputum and blood cultures, but stepwise resistance developed and the patient died 3 months after admission. DISCUSSION: Breast abscesses are infrequent in nonlactating women. P. aeruginosa is rarely involved, even in HIV patients. Due to the risk of resistance, prompt administration of appropriate antibiotics is required.
