Hospitalization of children born to human immunodeficiency virus- infected women in Europe
Objective. To describe the pattern of inpatient hospital service use in the first 5 years of life of all children born to HIV-infected women in 10 pediatric centers of the European Collaborative Study. Background. Little information is available on the need for hospitalization of children born to HIV-infected women, especially those uninfected, despite the fact that they may be at risk of social deprivation and poor health because of family cicumstances. Methods. Data on 1189 children enrolled between 1986 and 1997 and followed prospectively since birth according to a standard protocol were analyzed. Results. This analysis included 151 HIV-infected and 811 uninfected children. One hundred forty (12%) infants had delayed postnatal discharge, mainly for drug withdrawal symptoms and prematurity. Uninfected children had 0.5 admission per 5 child years compared with 2.4 for infected children. From life table analysis, an estimated 48% of infected and 17% of uninfected children will have been admitted by age 12 months. Nearly 60% (3304 of 5604) of the total inpatient days of infected children occurred after AIDS diagnosis. Infected children were 4 times more likely to be hospitalized than uninfected children of the same age, and children with symptomatic mothers were 13 times more likely to be admitted for a nonmedical reason. Conclusions. Whereas hospitalization of infected children poses an expected burden on the health care system, the use of such services by uninfected children is largely explained by their social background and provides an argument for better support for families affected by HIV.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
CD4 cell response to antiretroviral therapy in children with vertically acquired HIV infection: Is it associated with age at initiation?
Background. Considerable uncertainty remains as to whether early initiation of antiretroviral therapy (ART) in children with vertically acquired human immunodeficiency virus (HIV) infection increases the benefit in terms of immunological response. Methods. The association between immunological outcome and early initiation of and/or more-potent ART was investigated, using age-standardized z scores for CD4 cell counts (hereafter, "CD4 z scores"), in 131 HIV-infected children enrolled in the European Collaborative Study, a birth cohort study. Results. Median age at initiation of the most-potent ART was 4 years (range, 0.1-15.5 years). Initiation of treatment after 5 months of age resulted in nonsignificantly lower CD4 z scores 6 months after initiation. Time to a 20% increase in CD4 z score was associated with age at initiation of the most-potent ART (adjusted hazard ratios [AHRs], 0.37 [P5 years of age, respectively, compared with <5 months of age), ethnicity (AHR, 0.48 [P = .01], for black vs. white), and highly active ART (HAART) with or without prior ART (AHRs, 3.16 [P<.01] and 3.95 [P<.001], vs. mono or dual ART, respectively). The risk of subsequent deterioration of CD4 z score was similar for children who initiated ART in different age groups (χ2 = 0.824; P = .82). Conclusions. We confirm the effectiveness of HAART with respect to the recovery of CD4 cell count and suggest a benefit of initiating ART before the age of 5 months. Age at initiation of the most-potent ART was not associated with the likelihood of sustaining the recovery of CD4 cell count. © 2006 by the Infectious Diseases Society of America.

The mother-to-child HIV transmission epidemic in Europe: Evolving in the East and established in the West
OBJECTIVES: To carry out an epidemiological analysis of the emerging epidemic in an Eastern European country and to compare the approach to prevention of mother-to-child transmission (MTCT) with that in Western Europe. DESIGN: Prospective cohort study established in 1985 in Western Europe and extended to Ukraine in 2000. METHODS: Data on 5967 HIV-infected pregnant women and their infants (1251 from Ukraine and 4716 from Western/Central Europe) was analysed. Factors associated with transmission were identified with logistic regression. RESULTS: HIV-infection among pregnant women enrolled in Western European centres has shifted from being largely injecting drug use (IDU)-related to heterosexually-acquired; in Ukraine IDU also gradually declined with women increasingly identified without specific risk factors. In Ukraine in 2000-2004 most (80%) women received single dose nevirapine (sdNVP) and/or short-course zidovudine prophylaxis [MTCT rate 4.2%; 95% confidence interval (CI), 1.8-8.0 for sdNVP with short-course zidovudine]; 2% (n = 27) received antenatal HAART and 33% (n = 418) delivered by elective caesarean section (CS); in Western European centres 72% of women received HAART (MTCT rate 1.0%; 95% CI, 0.4-1.9) and 66% delivered by elective CS during the same period. CONCLUSIONS: Our findings indicate distinct differences in the epidemics in pregnant women across Europe. The evolution of the MTCT epidemic in Ukraine does not appear to be following the same pattern as that in Western Europe in the 1980s and 1990s. Although uptake of preventive MTCT prophylaxis has been rapid in both Western Europe and Ukraine, substantial challenges remain in the more resource-constrained setting in Eastern Europe. © 2006 Lippincott Williams & Wilkins.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
