Safety and pharmacokinetics of nelfinavir coadministered with zidovudine and lamivudine in infants during the first 6 weeks of life.
The safety and pharmacokinetics of nelfinavir coadministered with zidovudine and lamivudine were studied in 26 infants during the first 6 weeks of life. Cohort 1 infants (n = 7) received 10 mg/kg 3 times a day, and cohort 2 infants (n = 19) received 40 mg/kg twice a day. Two cohort 1 infants at week 1 and none at week 6 exceeded the target 24-hour area under the curve (AUC) of 30 mug.h/mL, equal to the 10th percentile of the AUC for adults receiving standard nelfinavir dosing. In cohort 2, the median 24-hour AUC was 38 mug.h/mL at both time points, with considerable variability among the infants. Three of 11 cohort 2 infants at week 1 and 4 of 11 at week 6 did not meet the AUC target. Median nelfinavir oral clearance was 2.1 L/h/kg at weeks 1 and 6. The median ratio of the plasma concentrations of the nelfinavir metabolite M8 to unchanged nelfinavir increased from 0.16 (range: 0-0.38) during week 1 to 0.56 (range: 0.4-1.47) during week 6 (P < 0.01). There were no significant differences in any of the other pharmacokinetic parameters when week 1 and week 6 results were compared. Few adverse events were attributed to nelfinavir. These data suggest that nelfinavir is well tolerated in infants at these doses, but exposure was frequently less than that seen in adults taking standard nelfinavir dosing. Further investigations of larger doses, such as 75 mg/kg twice a day, should be undertaken.

Changing pattern of AIDS: a bone marrow study.
We compared bone marrow findings in 2 groups of patients with AIDS during 2 different periods: group 1, n = 20; male/female ratio, 19/1; and group 2, n = 120; male/female ratio, 6/1. Bone marrow iron stores were decreased significantly in group 2 (P < .01), and the incidence of AIDS-related lymphomas was higher, with frequent bone marrow involvement. Two group 1 patients had Kaposi sarcoma, and a 21-month-old girl with transfusion-transmitted AIDS had Burkitt-like lymphoma. In group 2, 44 patients had a history of malignant neoplasms, including Kaposi sarcoma (10 cases), hematologic neoplasms (33 cases), and metastatic leiomyosarcoma (1 case). Of the 120 patients, 15 (12.5%) had bone marrow involvement by malignant neoplasms. The majority of the non-Hodgkin lymphomas were high-grade lymphomas. Patients with AIDS-related malignant neoplasms had higher CD4+ cell counts and viral loads than patients without malignant neoplasms (P < .01, P < .05, respectively). The finding of decreased iron stores in patients with AIDS might aid clinical management of their anemia. The increased incidence of malignant neoplasms, especially lymphomas, in recent years might be related to prolonged survival but with incomplete reconstitution of immune function after antiretroviral therapy.
