HIV type 1 group M clades infecting subjects from rural villages in equatorial rain forests of Cameroon.
Though the HIV-1 subtypes infecting patients living in urban and semi-urban areas in Cameroon have been reported, information on the subtypes infecting patients in rural villages is lacking. To begin to understand the diversity of the HIV-1 group M subtypes infecting persons living in rural villages in the equatorial rain forest regions of Cameroon, 49 plasma samples from 14 rural villages in four provinces of Cameroon were analyzed using heteroduplex mobility analysis (HMA), DNA sequencing, and phylogenetic tree analysis on the basis of env C2V5, gag, or pol regions. Sixty-one percent of the group M infections were clade A or CRF02_AG-like as subtyped by env and gag. ⋯ The CRF strains identified were CRF02_AG-like, CRF01_AE-like, and CRF11_cpx. Two new intersubtype recombinant infections, H/G and A/F2, were identified. This study suggests that the HIV-1 diversity in rural villages in the equatorial rain forest of Cameroon is at least as broad as has been observed in major cities of Cameroon and that multiple HIV-1 group M subtypes are infecting persons living in the countryside of Cameroon.

Opportunity for prevention of HIV and sexually transmitted infections in Kenyan youth: results of a population-based survey.
Data from sentinel serosurveillance are useful to estimate HIV infection in populations but may not be representative of the general population. General population-based surveys attempt to avoid selection bias and are the most appropriate for tracking changes in exposure to risk of HIV infection over time and assessing changes in behavior following prevention campaigns. ⋯ This study emphasizes the vulnerability of young adults, in particular young women, to HIV infection and the need for intensive interventions in this group. The low use of condoms, incomplete knowledge of HIV infection and STIs, the high number of reported STIs, and the relatively low HIV-1 seroprevalence among the 15- to 19-year-old group indicate a large need for intensive STI and HIV infection prevention programs, especially for the 15- to 19-year-old age group.

Pulmonary infiltrates in HIV-infected patients in the highly active antiretroviral therapy era in Spain.
To study the incidence, etiology, and outcome of pulmonary infiltrates (PIs) in HIV-infected patients and to evaluate the yield of diagnostic procedures. ⋯ Pulmonary infiltrates are still a frequent cause of hospital admission in the HAART era, and BP is the main etiology. There was no difference in the rate of BP and mycobacteriosis in HAART and non-HAART patients. Not having an etiologic diagnosis is an independent factor associated with mortality.

Multicenter Study Clinical TrialMode of delivery and postpartum morbidity among HIV-infected women: the women and infants transmission study.
Cesarean delivery before onset of labor and rupture of membranes (i.e., scheduled cesarean delivery) is associated with a lower risk of vertical transmission of HIV. The following a priori hypotheses were tested: among HIV-infected women, scheduled cesarean delivery is associated with a higher risk of postpartum morbidity, longer hospitalization, and a higher risk of rehospitalization than spontaneous vaginal delivery. Postpartum morbidity occurred following 178 of 1,186 (15%) of deliveries during 1990 to 1998 in The Women and Infants Transmission Study. ⋯ Results of this analysis indicate scheduled cesarean delivery is associated with an increased risk of any postpartum morbidity and, specifically, postpartum fever without infection. The potential for postpartum morbidity with scheduled cesarean delivery should be considered in light of possible adverse events associated with other interventions to decrease the risk of vertical transmission of HIV. Counseling of HIV-infected pregnant women regarding scheduled cesarean delivery as a possible intervention to decrease maternal-infant transmission of HIV should include discussion of these results, as well as new data as they become available, regarding the incidence and severity of postpartum morbidity events among HIV-infected women according to mode of delivery.

Restoration of cellular immunity against tuberculosis in patients coinfected with HIV-1 and tuberculosis with effective antiretroviral therapy: assessment by determination of CD69 expression on T cells after tuberculin stimulation.
Whether immunity against opportunistic pathogens can be fully restored by control of HIV-1 replication remains open to question. This longitudinal study was conducted to measure anti-tuberculosis (TB) cellular immunity in 13 HIV-1/TB-coinfected patients effectively treated by highly active antiretroviral therapy (HAART) in a period of 12 months. In this study, anti-TB cellular immunity was assessed by determining the frequencies of CD 69 expression on CD4+ and CD8+ T cells in response to purified protein derivative (PPD) stimulation (abbreviated as %CD4+CD69 to PPD and %CD8+CD69 to PPD). ⋯ Our results indicate that PPD-specific frequencies of CD69 expression may be used as surrogate markers of anti-TB cellular immunity. By this method, we show that full reconstitution of anti-TB cellular immunity in HIV-1/TB coinfected patients may not necessarily be achieved by "successful" HAART and may be influenced by the baseline immune status when HAART is started. These data suggest that the decision to discontinue secondary prophylaxis for opportunistic infections should be cautiously made, even when the CD4+ cell count has significantly increased.
