 AB    The aim of this study was to determine immunological factors associated
       with increased risk of mother-to-child transmission of HIV-1 that could
       be used as predictive markers in Tanzanian women. One hundred and
       thirty-eight HIV-1-seropositive and 117-seronegative mothers and their
       newborns were recruited at delivery and followed up at Muhimbili Medical
       Centre in Dar es Salaam, Tanzania. Blood specimens from the mothers were
       analyzed for HIV-1 p24 antigen, beta 2-microglobulin (B2M), T-lymphocyte
       subsets, and presence of viral DNA in blood mononuclear cells by the
       polymerase chain reaction (PCR). Among 138 seropositive mothers, 30
       (21.7%) had transmitted HIV-1 to their children, as shown by a positive
       PCR in the child. The vertical transmission rate was significantly
       higher in women with a percentage of CD4 lymphocytes < or = 20 (eight of
       24, 33%) or a level of B2M > or = 2 mg/L (21 of 62, 34%) than in women
       with a higher percentage of CD4 lymphocytes (10 of 73, 14%) or a lower
       level of B2M (eight of 57, 14%) (p = 0.034 and 0.018, respectively). In
       eight of 18 (44%) transmitting mothers the percentage of CD4 lymphocytes
       was < or = 20, and in 21 of 29 (72%) transmitting mothers the B2M level
       was > or = 2 mg/L. In women with both a low percentage of CD4
       lymphocytes (< or = 20) and a high level of B2M (> or = 2 mg/L), the
       vertical transmission rate was 54%.(ABSTRACT TRUNCATED AT 250 WORDS)
