Results of the ALBI trial: a randomized comparison of stavudine/didanosine, zidovudine/lamivudine and alternating treatment in antiretroviral-naive patients.

In the ALBI trial, 151 antiretroviral-naive patients with plasma human immunodeficiency virus type 1 (HIV-1) RNA levels of 10,000 to 100,000 copies/ml and CD4 cell counts > or = 200 cells/mm3 received 24 weeks of treatment with stavudine/didanosine (n=51), zidovudine/lamivudine (n=51) or stavudine/didanosine for 12 weeks followed by zidovudine/lamivudine (n=49). Baseline plasma HIV-1 RNA and CD4 cell counts were comparable in the treatment groups. The mean decrease in plasma HIV-1 RNA at 24 weeks in the stavudine/didanosine group (2.

The ALBI trial: a randomized controlled trial comparing stavudine plus didanosine with zidovudine plus lamivudine and a regimen alternating both combinations in previously untreated patients infected with human immunodeficiency virus.

A total of 151 previously untreated patients infected with human immunodeficiency virus type 1 (HIV-1) with CD4 cell counts >/=200/microL and plasma HIV-1 RNA levels of 10,000-100,000 copies/mL were randomly assigned to 24 weeks of open-labeled stavudine plus didanosine (group 1), zidovudine plus lamivudine (group 2), or stavudine plus didanosine followed by zidovudine plus lamivudine (group 3). The mean decrease in HIV-1 RNA level was greater in group 1 (2.26 log10 copies/mL) than in groups 2 (1.

Risk factors for intestinal microsporidiosis in patients with human immunodeficiency virus infection: a case-control study.

A prospective unmatched case-control study was conducted to determine risk factors for intestinal microsporidiosis in persons infected with human immunodeficiency virus (HIV) who had < or = 200 CD4 cells/mm3. In multivariate analysis, case-patients (n = 30) were more likely than were control-subjects (n = 56) to have < or = 100 CD4 cells/mm3 (odds ratio [OR], 6.5; 95% confidence interval [CI], 1-42), to report male homosexual preference (OR, 7.

Gene transfer to human fetal pulmonary tissue developed in immunodeficient SCID mice.

Human fetal lung rudiments (8-12 weeks of development) undergo considerable growth upon microsurgical ectopic implantation in the xenograft-tolerant SCID mouse, and differentiate into a lung-like tissue that includes: (i) bronchial structures lined with pseudostratified, secretory, ciliated epithelium surrounded by smooth muscle and cartilage rings, (ii) submucosal glands, and (iii) alveolar sacs. Normal expression of the cystic fibrosis transmembrane conductance regulator (CFTR) protein was detected by immunostaining in those grafts, and similar differentiation was observed from either normal or cystic fibrosis (CF) fetal lung rudiments. Upon microinjection into human CF or normal lung grafts in SCID mice, beta-galactosidase-adenovirus gene constructs were efficiently transduced into epithelial and glandular cells.
