Group B Streptococcus in a cohort of HIV-infected pregnant women: prevalence of colonization, identification and antimicrobial susceptibility profile.

Group B Streptococcus (GBS) is a leading cause of infectious morbidity in newborns. We describe the prevalence of GBS colonization and the serotypes and antibiotic susceptibility profiles of isolates obtained from a cohort of human immunodeficiency virus (HIV)-infected pregnant women. This was a cross-sectional study at a centre for the prevention of mother-to-child transmission of HIV. Vaginal and rectal swabs were collected at 35-37 weeks of gestation from 158 eligible women. GBS isolates were serotyped and antimicrobial susceptibility tests performed. Patient sociodemographic characteristics, CD4 counts and viral loads were abstracted from records. The overall anogenital prevalence of GBS colonization was 49/158 (31.0%): 40/158 (25.3%) for vagina, 19/158 (12.0%) for rectum and 10/158 (6.3%) for both. Predominant serotypes were Ib (34.9%) and Ia (25.6%). All were penicillin-susceptible. Two were resistant to erythromycin (4.0%) and one to clindamycin (2.0%). The colonization rate by GBS was high in this cohort. Serotype Ib was the most frequently identified.

Nevirapine toxicity in a cohort of HIV-1-infected pregnant women.

OBJECTIVE: The purpose of this study was to complete an evaluation of nevirapine (NVP) toxicity in a cohort of HIV+ pregnant women. STUDY DESIGN: This was a retrospective study of 611 women followed from January 1996 to December 2003. All women who used NVP for > 7 days were included. Multivariate logistic regression was used to test independent association of CD4 and hepatitis C virus (HCV) infection related to the outcome of toxic effects of NVP. RESULTS: One hundred ninety-seven women were exposed to NVP for > 7 days, and toxicity occurred in 11 (5.6%), leading to drug discontinuation in 7 patients. One case of Stevens-Johnson syndrome occurred. No serious liver toxicity occurred except for 1 grade 4 cholestasis. Median CD4 was 344 in women without toxicities and 298 in women with toxicities. HCV was the only significant factor associated to toxicity by logistic regression (odds ratio [OR] 15.61, P = .001). CONCLUSION: NVP toxicities occurred in a very small fraction of patients and were not associated with fatalities.

Perinatally infected adolescents living with human immunodeficiency virus (perinatally human immunodeficiency virus).

The availability of highly potent antiretroviral treatment during the last decades has transformed human immunodeficiency virus (HIV) infection into a chronic disease. Children that were diagnosed during the first months or years of life and received treatment, are living longer and better and are presently reaching adolescence and adulthood. Perinatally HIV-infected adolescents (PHIV) and young adults may present specific clinical, behavior and social characteristics and demands. We have performed a literature review about different aspects that have to be considered in the care and follow-up of PHIV. The search included papers in the MEDLINE database via PubMed, located using the keywords "perinatally HIV-infected" AND "adolescents". Only articles published in English or Portuguese from 2003 to 2014 were selected. The types of articles included original research, systematic reviews, and quantitative or qualitative studies; case reports and case series were excluded. Results are presented in the following topics: "Puberal development and sexual maturation", "Growth in weight and height", "Bone metabolism during adolescence", "Metabolic complications", "Brain development, cognition and mental health", "Reproductive health", "Viral drug resistance" and "Transition to adult outpatient care". We hope that this review will support the work of pediatricians, clinicians and infectious diseases specialists that are receiving these subjects to continue treatment.

Association of Body Mass Index of HIV-1-Infected Pregnant Women and Infant Weight, Body Mass Index, Length, and Head Circumference: The NISDI Perinatal Study.

This study assessed the relationship between the body mass index (BMI) of HIV-1-infected women and their infants' perinatal outcomes. The study population consisted of women enrolled in the NICHD International Site Development Initiative (NISDI) Perinatal Study with data allowing calculation of the BMI adjusted for length of gestation (adjBMI), who delivered singleton infants. Outcome variables included infant growth parameters at birth (weight, BMI, length and head circumference) and gestational age. Of 697 women from Argentina, the Bahamas, Brazil and Mexico who were included in the analysis, the adjBMI was classified as underweight for 109 (15.6%), normal for 418 (60.0%), overweight for 88 (12.6%) and obese for 82 (11.8%). Median infant birth weight, BMI, birth length and head circumference differed significantly according to maternal adjBMI (P
