title: Pneumocystis carinii pneumonia in Stockholm, Sweden: treatment, outcome, one-year-follow-up and pyrimethamine prophylaxis.
abstract: In 33 consecutive AIDS patients with a first episode of Pneumocystis carinii pneumonia (PCP) we evaluated treatment, outcome, recurrence rate and pyrimethamine as chemoprophylaxis in a 1-year follow-up. Only 2 patients had a CD4 lymphocyte cell count greater than 0.2 X 10(9)/l. Trimethoprim-sulfamethoxazole (TMP-SMX) was initially given to 32 patients but in 20 of these patients severe adverse reactions caused us to discontinue treatment. Of these 20 patients 11 were started on i.v./i.m. pentamidine but in 6 adverse reactions forced us to withdraw pentamidine. Patients were retrospectively divided with regard to duration of therapy into 2 groups. We could not find any difference between patients in Group 1 treated for less than or equal to 14 days and patients in Group 2 treated for greater than 14 days when comparing outcome, number of recurrences and mean time until recurrence. In 16/21 patients given only TMP-SMX initially in a high dose (means = 16 mg trimethoprim/kg/day), dose reduction was performed to means = 10.5 mg trimethoprim/kg/day after a mean time of 6.9 days. The case-fatality rate for these patients was 10% (2/21) and the overall case-fatality rate was 15% (5/33). We chose pyrimethamine (50-175 mg/week) as secondary prophylaxis for PCP. At 1-year follow-up another 16 patients had died (21/32) and 9/27 (33%) discharged patients had had one recurrence each of PCP. All recurrences occurred among patients treated with only TMP-SMX for the acute episode of PCP. Of these 27 discharged patients 23 had been given pyrimethamine and 8 (36%) of these had experienced a recurrence.(ABSTRACT TRUNCATED AT 250 WORDS)
