RESUMEN

BACKGROUND: Published estimates of mortality and progression to AIDS as children with HIV approach adulthood are limited. We describe rates and risk factors for death and AIDS-defining events in children and adolescents after initiation of combination antiretroviral therapy (cART) in 17 middle- and high-income countries, including some in Western and Central Europe (W&CE), Eastern Europe (Russia and Ukraine), and Thailand. METHODS AND FINDINGS: Children with perinatal HIV aged <18 years initiating cART were followed until their 21st birthday, transfer to adult care, death, loss to follow-up, or last visit up until 31 December 2013. Rates of death and first AIDS-defining events were calculated. Baseline and time-updated risk factors for early/late (≤/>6 months of cART) death and progression to AIDS were assessed. Of 3,526 children included, 32% were from the United Kingdom or Ireland, 30% from elsewhere in W&CE, 18% from Russia or Ukraine, and 20% from Thailand. At cART initiation, median age was 5.2 (IQR 1.4-9.3) years; 35% of children aged <5 years had a CD4 lymphocyte percentage <15% in 1997-2003, which fell to 15% of children in 2011 onwards (p < 0.001). Similarly, 53% and 18% of children ≥5 years had a CD4 count <200 cells/mm3 in 1997-2003 and in 2011 onwards, respectively (p < 0.001). Median follow-up was 5.6 (2.9-8.7) years. Of 94 deaths and 237 first AIDS-defining events, 43 (46%) and 100 (42%) were within 6 months of initiating cART, respectively. Multivariable predictors of early death were: being in the first year of life; residence in Russia, Ukraine, or Thailand; AIDS at cART start; initiating cART on a nonnucleoside reverse transcriptase inhibitor (NNRTI)-based regimen; severe immune suppression; and low BMI-for-age z-score. Current severe immune suppression, low current BMI-for-age z-score, and current viral load >400 c/mL predicted late death. Predictors of early and late progression to AIDS were similar. Study limitations include incomplete recording of US Centers for Disease Control (CDC) disease stage B events and serious adverse events in some countries; events that were distributed over a long time period, and that we lacked power to analyse trends in patterns and causes of death over time. CONCLUSIONS: In our study, 3,526 children and adolescents with perinatal HIV infection initiated antiretroviral therapy (ART) in countries in Europe and Thailand. We observed that over 40% of deaths occurred ≤6 months after cART initiation. Greater early mortality risk in infants, as compared to older children, and in Russia, Ukraine, or Thailand as compared to W&CE, raises concern. Current severe immune suppression, being underweight, and unsuppressed viral load were associated with a higher risk of death at >6 months after initiation of cART.

RESUMEN

Background: The human immunodeficiency virus (HIV) epidemic in Ukraine has been driven by a rapid rise among people who inject drugs, but recent studies have shown an increase through sexual transmission. Methods: Protease and reverse transcriptase sequences from 876 new HIV diagnoses (April 2013-March 2015) in Kiev were linked to demographic data. We constructed phylogenetic trees for 794 subtype A1 and 64 subtype B sequences and identified factors associated with transmission clustering. Clusters were defined as ≥2 sequences, ≥80% local branch support, and maximum genetic distance of all sequence pairs in the cluster ≤2.5%. Recent infection was determined through the limiting antigen avidity enzyme immunoassay. Sequences were analyzed for transmitted drug resistance mutations. Results: Thirty percent of subtype A1 and 66% of subtype B sequences clustered. Large clusters (maximum 11 sequences) contained mixed risk groups. In univariate analysis, clustering was significantly associated with subtype B compared to A1 (odds ratio [OR], 4.38 [95% confidence interval {CI}, 2.56-7.50]); risk group (OR, 5.65 [95% CI, 3.27-9.75]) for men who have sex with men compared to heterosexual males; recent, compared to long-standing, infection (OR, 2.72 [95% CI, 1.64-4.52]); reported sex work contact (OR, 1.93 [95% CI, 1.07-3.47]); and younger age groups compared with age ≥36 years (OR, 1.83 [95% CI, 1.10-3.05] for age ≤25 years). Females were associated with lower odds of clustering than heterosexual males (OR, 0.49 [95% CI, .31-.77]). In multivariate analysis, risk group, subtype, and age group were independently associated with clustering (P < .001, P = .007, and P = .033, respectively). Eighteen sequences (2.1%) indicated evidence of transmitted drug resistance. Conclusions: Our findings suggest high levels of transmission and bridging between risk groups.

RESUMEN

Ukraine has one of the largest populations of persons living with HIV in Europe. Data on 2019 HIV-positive married or cohabiting women enrolled in a postnatal cohort from 2007 to 2012 were analysed to investigate prevalence and factors associated with self-reported non-disclosure of HIV status. Median age at enrolment was 27.5 years, with two-thirds diagnosed during their most recent pregnancy. Almost all had received antenatal antiretroviral therapy and 24 % were taking it currently. One-tenth (n = 198) had not disclosed their HIV status to their partner and 1 in 20 (n = 93) had disclosed to no-one. Factors associated with non-disclosure were: unmarried status (AOR 2.99 (95 % CI 1.51-5.92), younger age at leaving full-time education (AOR 0.41 (95 % CI 0.19-0.88) for ≥19 years vs ≤16 years) and lack of knowledge of partner's HIV status (AOR 2.01 (95 % CI 1.09-3.66). Further work is needed to support disclosure in some groups and to explore relationships between disclosure and psychological factors in this setting, including depression, lack of support and perception of stigma.

RESUMEN

BACKGROUND: Ukraine's injecting drug use-driven HIV epidemic is among the most severe in Europe with high burden of HCV co-infection. HIV/HCV co-infected individuals are at elevated risk of HCV-related morbidity, but little is known about burden of liver disease and associated factors in the HIV-positive population in Ukraine, particularly among women. METHODS: Characteristics of 2050 HIV-positive women enrolled into the Ukrainian Study of HIV-infected Childbearing Women were described by HCV serostatus. Aspartate transaminase (AST) to platelet ratio (APRI) and FIB-4 scores were calculated and exact logistic regression models fitted to investigate factors associated with significant fibrosis (APRI >1.5) among 762 women with an APRI score available. RESULTS: Of 2050 HIV-positive women (median age 27.7 years, IQR 24.6-31.3), 33% were HCV co-infected (79% of those with a history of injecting drug use vs 23% without) and 17% HBsAg positive. A quarter were on antiretroviral therapy at postnatal cohort enrolment. 1% of the HIV/HCV co-infected group had ever received treatment for HCV. Overall, 24% had an alanine aminotransferase level >41 U/L and 34% an elevated AST (53% and 61% among HIV/HCV co-infected). Prevalence of significant fibrosis was 4.5%; 2.5% among 445 HIV mono-infected and 12.3% among 171 HIV/HCV co-infected women. 1.2% had a FIB-4 score >3.25 indicating advanced fibrosis. HCV RNA testing in a sub-group of 56 HIV/HCV co-infected women indicated a likely spontaneous clearance rate of 18% and predominance of HCV genotype 1, with one-third having genotype 3 infection. Factors associated with significant fibrosis were HCV co-infection (AOR 2.53 95%CI 1.03-6.23), history of injecting drug use (AOR 3.51 95%CI 1.39-8.89), WHO stage 3-4 HIV disease (AOR 3.47 95%CI 1.51-7.99 vs stage 1-2 HIV disease) and not being on combination antiretroviral therapy (AOR 3.08 95%CI 1.23-7.74), adjusted additionally for HBV co-infection, smoking and age. CONCLUSIONS: Most HIV/HCV co-infected women had elevated liver enzymes and 12% had significant fibrosis according to APRI. Risk factors for liver fibrosis in this young HIV-positive population include poorly controlled HIV and high burden of HCV. Results highlight the importance of addressing modifiable risk factors and rolling out HCV treatment to improve the health outcomes of this group.

RESUMEN

BACKGROUND: Over 3500 HIV-positive women give birth annually in Ukraine, a setting with high prevalence of sexually transmitted infections. Herpes simplex virus Type 2 (HSV-2) co-infection may increase HIV mother-to-child transmission (MTCT) risk. We explored factors associated with HSV-2 seropositivity among HIV-positive women in Ukraine, and its impact on HIV MTCT. METHODS: Data on 1513 HIV-positive women enrolled in the Ukraine European Collaborative Study from 2007 to 2012 were analysed. Poisson and logistic regression models respectively were fit to investigate factors associated with HSV-2 seropositivity and HIV MTCT. RESULTS: Median maternal age was 27 years (IQR 24-31), 53% (796/1513) had been diagnosed with HIV during their most recent pregnancy and 20% had a history of injecting drugs. Median antenatal CD4 count was 430 cells/mm(3) (IQR 290-580). Ninety-six percent had received antiretroviral therapy antenatally. HSV-2 seroprevalence was 68% (1026/1513). In adjusted analyses, factors associated with HSV-2 antibodies were history of pregnancy termination (APR 1.30 (95% CI 1.18-1.43) for ≥ 2 vs. 0), having an HIV-positive partner (APR 1.15 (95% CI 1.05-1.26) vs partner's HIV status unknown) and HCV seropositivity (APR 1.23 (95 % CI 1.13-1.35)). The overall HIV MTCT rate was 2.80% (95% CI 1.98-3.84); no increased HIV MTCT risk was detected among HSV-2 seropositive women after adjusting for known risk factors (AOR 1.43 (95% CI 0.54-3.77). CONCLUSION: No increased risk of HIV MTCT was detected among the 68% of HIV-positive women with antibodies to HSV-2, in this population with an overall HIV MTCT rate of 2.8%. Markers of ongoing sexual risk among HIV-positive HSV-2 seronegative women indicate the importance of interventions to prevent primary HSV-2 infection during pregnancy in this high-risk group.

RESUMEN

BACKGROUND: Perinatal depression among HIV-positive women has negative implications for HIV-related and other maternal and infant outcomes. The aim of this study was to investigate the burden and correlates of perinatal depression among HIV-positive women in Ukraine, a lower middle income country with one of the largest HIV-positive populations in Europe. METHODS: Cross-sectional surveys nested within the Ukraine European Collaborative Study were conducted of HIV-positive women at delivery and between 1 and 12 months postpartum. Depressive symptoms in the previous month were assessed using a self-report screening tool. Other data collected included demographics, antiretroviral therapy (ART)-related self-efficacy, and perceptions of risks/benefits of interventions to prevent mother-to-child transmission (PMTCT). Characteristics of women with and without a positive depression screening test result were compared using Fisher's exact test and χ2 test for categorical variables. RESULTS: A quarter (27% (49/180) antenatally and 25% (57/228) postnatally) of participants screened positive for depressive symptoms. Antenatal risk factors were living alone (58% (7/12) vs. 25% (42/167) p = 0.02), being somewhat/terribly bothered by ART side effects (40% (17/43) vs. 23% (30/129) not /only slightly bothered, p = 0.05) and having lower ART-related self-efficacy (43% (12/28) vs. 23% (25/110) with higher self-efficacy, p = 0.05). Postnatally, single mothers were more likely to screen positive (44% (20/45) vs. 21% (18/84) of cohabiting and 19% (19/99) of married women, p < 0.01) as were those unsure of the effectiveness of neonatal prophylaxis (40% (20/45) vs. 18% (28/154) sure of effectiveness, p < 0.01), those worried that neonatal prophylaxis could harm the baby (30% (44/146) vs. 14% (10/73) not worried p < 0.01) and those not confident to ask for help with taking ART (48% (11/23) vs. 27% (10/37) fairly confident and 15 % (4/26) confident that they could do this). Of women who reported wanting help for their depressive symptoms, 82% (37/45) postnatally but only 31% (12/39) antenatally were already accessing peer counselling, treatment adherence programmes, support groups or social services. CONCLUSIONS: A quarter of women screened positive for depression. Results highlight the need for proactive strategies to identify depressive symptoms, and an unmet need for provision of mental health support in the perinatal period for HIV-positive women in Ukraine.

RESUMEN

The proportion of new HIV diagnoses between May and December 2009 across Odessa recently-infected was estimated using the BED-CEIA assay. Logistic regression models were used to explore factors associated with testing as recent. Of 1,313 newly-diagnosed individuals, 321 (24 %) were classified as recent. Recent infection was less likely among older adults [odds ratio (OR) = 0.70 per 10-year increase, 95 % CI 0.60-0.82]. Compared to men residing in Odessa city, women in rural Odessa and non-resident men were more likely to be recently-infected (OR 1.85, 1.26-2.71 and 2.83, 1.15-6.97, respectively). Reason for test was not associated with recent infection. In sensitivity analysis, after excluding individuals tested due to clinical indications, the proportion recently-infected and the association with age remained virtually unchanged. Our findings suggest a high risk of onward transmission, particularly in younger age groups. These findings highlight the need for tailored prevention strategies and ongoing RITA testing to monitor and evaluate effectiveness of prevention programmes.

RESUMEN

BACKGROUND: Poor adherence to antiretroviral therapy (ART) is associated with HIV disease progression and, during pregnancy, increased mother-to-child transmission risk. In Ukraine, access to combination ART is expanding but data on adherence are scarce. METHODS: Cross-sectional surveys of HIV-positive women were conducted i) at delivery (on antenatal ART adherence) and ii) during the first year postpartum (on ART adherence in the preceding four weeks). Factors associated with a score ≤ 11 on the self-report Case Adherence Support Evaluation (CASE) index or ≥ 1 self-reported missed dose were assessed using Fisher's exact test. RESULTS: Of 185 antenatal participants and 102 postnatal participants, median ages were 27.5 and 29.5 years respectively: 28% (50/180) and 27% (26/98) reported an unplanned pregnancy, and 13% (24/179) and 17% (17/98) an illicit drug-use history (excluding marijuana). One quarter (49/180 antenatally, 27/101 postnatally) screened positive for depression. The proportion reporting 'low' ART-related self-efficacy (i.e. unable to do ≥ 1/5 ART-taking activities) was 20% (28/141) antenatally and 17% (11/66) postnatally. Antenatally, 14% (95% CI 10-21%) had a CASE score ≤ 11 and 35% (95% CI 28-42%) reported missing ≥ 1 dose. Factors associated with a CASE score ≤ 11 were unplanned pregnancy (25% (12/48) vs. 11% (13/120) where planned, p = 0.03) and living with extended family (23% (13/57) vs. 10% (12/125) living with partner/alone, p = 0.04). Self-report of ≥ 1 missed dose antenatally was additionally associated with younger age (p = 0.03) and lower self-efficacy (50% (14/28) reported ≥ 1 missed dose vs. 28% (30/108) of those with high self-efficacy, p = 0.04). Of 102 postnatal participants, 8% (95% CI 4-15%) had a CASE score ≤ 11 and 31% (95% CI 22-41%) reported ≥ 1 missed dose. Of 11 women with low self-efficacy, 3 (27%) had a CASE score ≤ 11 compared with 3/55 (5%) of those with high self-efficacy (p = 0.05). Current smokers more commonly reported ≥ 1 missed dose postnatally (50% (13/26) vs. 25% (18/72) of non-smokers, p = 0.03). CONCLUSIONS: Our results highlight unmet needs for counselling and support. We identify some groups at risk of poor ART adherence, including women with markers of social vulnerability and those with low ART-related self-efficacy, who may benefit from targeted interventions.

RESUMEN

Chronic hepatitis C (HCV) in women of childbearing age is a major public health concern with ∼15 million women aged 15-49 years living with HCV globally in 2019. Evidence suggests HCV in pregnancy is associated with adverse pregnancy and infant outcomes. This includes ∼6% risk of infants acquiring HCV vertically, and this is the leading cause of HCV in children globally. However, few countries offer routine universal antenatal HCV screening, and direct-acting antivirals (DAAs) are not approved for pregnant or breastfeeding women although small clinical trials are ongoing. We conducted a survey of pregnant and postpartum women in 3 high HCV burden lower-middle-income countries to assess the acceptability of universal antenatal HCV screening and DAA treatment in the scenario that DAAs are approved for use in pregnancy. Pregnant and postpartum women attending antenatal clinics in Egypt, Pakistan, and Ukraine were invited to complete a survey and provide demographic and clinical data on their HCV status. Among the 630 women included (n=210 per country), 73% were pregnant and 27% postpartum, 27% were ever HCV antibody or PCR positive. Overall, 586 (93%) reported acceptability of universal antenatal HCV screening and 544 (88%) would take DAAs in pregnancy (92%, 98%, and 73% in Egypt, Pakistan, and Ukraine, respectively). Most said they would take DAAs in pregnancy to prevent vertical acquisition and other risks for the baby, and a smaller proportion would take DAAs for maternal cure. Our findings suggest that should DAAs be approved for use in pregnancy, the uptake of both HCV screening and DAA treatment may be high in women living in lower-middle-income countries.

RESUMEN

The top 20 highest burdened countries (in disability-adjusted life years) account for more than 75% of the global burden of viral hepatitis. An effective response in these 20 countries is crucial if global elimination targets are to be achieved. In this update of the Lancet Gastroenterology & Hepatology Commission on accelerating the elimination of viral hepatitis, we convene national experts from each of the top 20 highest burdened countries to provide an update on progress. Although the global burden of diseases is falling, progress towards elimination varies greatly by country. By use of a hepatitis elimination policy index conceived as part of the 2019 Commission, we measure countries' progress towards elimination. Progress in elimination policy has been made in 14 of 20 countries with the highest burden since 2018, with the most substantial gains observed in Bangladesh, India, Indonesia, Japan, and Russia. Most improvements are attributable to the publication of formalised national action plans for the elimination of viral hepatitis, provision of publicly funded screening programmes, and government subsidisation of antiviral treatments. Key themes that emerged from discussion between national commissioners from the highest burdened countries build on the original recommendations to accelerate the global elimination of viral hepatitis. These themes include the need for simplified models of care, improved access to appropriate diagnostics, financing initiatives, and rapid implementation of lessons from the COVID-19 pandemic.

RESUMEN

OBJECTIVE: To investigate the scale-up of antenatal combination antiretroviral therapy (cART) in Ukraine since this became part of the national policy for the prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV). METHODS: Data on 3535 HIV-positive pregnant women who were enrolled into the Ukraine European Collaborative Study in 2008-2010 were analysed. Factors associated with receipt of zidovudine monotherapy (AZTm) - rather than cART - and rates of mother-to-child transmission (MTCT) of HIV were investigated. FINDINGS: cART coverage increased significantly, from 22% of deliveries in 2008 to 61% of those in 2010. After adjusting for possible confounders, initiation of antenatal AZTm - rather than cART - was associated with cohabiting (versus being married; adjusted prevalence ratio, aPR: 1.09; 95% confidence interval, CI: 1.02-1.16), at least two previous live births (versus none; aPR: 1.22; 95% CI: 1.11-1.35) and a diagnosis of HIV infection during the first or second trimester (versus before pregnancy; aPR: 1.11; 95% CI: 1.03-1.20). The overall MTCT rate was 4.1% (95% CI: 3.4-4.9); 42% (49/116) of the transmissions were from the 8% (n = 238) of women without antenatal ART. Compared with AZTm, cART was associated with a 70% greater reduction in the risk of MTCT (adjusted odds ratio: 0.30; 95% CI: 0.16-0.56). CONCLUSION: Between 2008 and 2010, access to antenatal cART improved substantially in Ukraine, but implementation of the World Health Organization's Option-B policy was slow. For MTCT to be eliminated in Ukraine, improvements in the retention of women in HIV care and further roll-out of Option B are urgently needed.

RESUMEN

Direct-acting antivirals (DAAs) have been approved for treating chronic hepatitis C virus (HCV) in children and adolescents. Although DAAs have been used in real-world settings for the treatment of HCV monoinfected adolescents, few reports of real-world use of DAAs in children and adolescents who are coinfected with human immunodeficiency virus (HIV) are available. We evaluated the real-world safety and effectiveness of DAAs in HIV/HCV coinfected adolescents from the Ukraine Paediatric HIV Cohort Study including all those for whom treatment outcomes were available by April 2021. Overall, 6 coinfected adolescents had received DAA treatment; 4 with sofosbuvir/ledipasvir (SOF/LDV), 1 with SOF/LDV+ribavirin, and 1 with SOF/daclatasvir. No patient discontinued treatment due to adverse events and no serious adverse events were reported. All 6 patients achieved sustained virologic response by 12 weeks after the end of therapy. DAA treatment was well tolerated and effective in adolescents with HIV/HCV coinfection in a real-world setting.

RESUMEN

Social marginalisation and other challenges facing HIV-positive pregnant women in Ukraine may put them at increased risk of relinquishing their infants to the state. We described rates of infant abandonment (exclusive non-parental care to most recent follow-up, censored at two years of age) and investigated associated factors using logistic regression models, in 4759 mother-infant pairs enrolled across six Ukrainian sites in the European Collaborative Study from 2000 to May 2009. Median maternal age was 26.0 years, 81.8% were married or cohabiting and 60.6% were nulliparous at enrolment. An injecting drug use (IDU) history was reported by 18.4%, 80.2% took antiretroviral therapy (ART) antenatally and most deliveries were vaginal. A small but significant proportion of infants had been cared for exclusively in institutions by their second birthday (2.1% overall), decreasing from 3.8% (15/393) in 2000-2002 to 1.6% (49/3136) in 2006-2009 (p<0.01), concurrent with prevention of mother-to-child transmission scale-up. A further 1% of infants spent some time in non-parental care. Antenatal ART was associated with an 88% reduced abandonment risk (adjusted odds ratio (AOR) 0.12), versus receipt of single dose nevirapine only, and this was reflected in HIV infection prevalence in the two groups (17.1% of abandoned infants versus 6.6% in parental care). Mothers without a cohabiting partner or husband were more likely to abandon (AOR 4.08), as were active IDUs (AOR 3.27) and those with ≥1 previous children (AOR 1.89 for second-born and AOR 2.56 for subsequent births). Women delivering by elective caesarean section were less likely to abandon (AOR 0.37 versus vaginal), as were those leaving full-time education later (AOR 0.61 for 17-18 years versus ≤16 years and AOR 0.23 for ≥19 years versus ≤16 years). Interventions to extend family planning and IDU harm reduction services along with non-stigmatising antenatal care to marginalised women are needed, and may reduce abandonment.

RESUMEN

BACKGROUND: Ukraine has the highest HIV prevalence (1.6%) and is facing the fastest growing epidemic in Europe. Our objective was to describe the clinical, immunological and virological characteristics, treatment and response in vertically HIV-infected children living in Ukraine and followed from birth. METHODS: The European Collaborative Study (ECS) is an ongoing cohort study, in which HIV-1 infected pregnant women are enrolled and followed in pregnancy, and their children prospectively followed from birth. ECS enrolment in Ukraine started in 2000 initially with three sites, increasing to seven sites by 2009. RESULTS: A total of 245 infected children were included in the cohort by April 2009, with a median age of 23 months at most recent follow-up; 33% (n = 77) had injecting drug using mothers and 85% (n = 209) were infected despite some use of antiretroviral prophylaxis for prevention of mother-to-child transmission. Fifty-five (22%) children had developed AIDS, at a median age of 10 months (IQR = 6-19). The most prevalent AIDS indicator disease was Pneumocystis jiroveci pneumonia (PCP). Twenty-seven (11%) children had died (median age, 6.2 months). Overall, 108 (44%) children had started highly active antiretroviral treatment (HAART), at a median 18 months of age; median HAART duration was 6.6 months to date. No child discontinued HAART and 92% (100/108) remained on their first-line HAART regimen to date. Among children with moderate/severe immunosuppression, 36% had not yet started HAART. Among children on HAART, 71% (69/97) had no evidence of immunosuppression at their most recent visit; the median reduction in HIV RNA was 4.69 log10 copies/mL over a median of 10 months treatment. From survival analysis, an estimated 94%, 84% and 81% of children will be alive and AIDS-free at 6, 12 and 18 months of age, respectively. However, survival increased significantly over time: estimated survival rates to 12 months of age were 87% for children born in 2000/03 versus 96% for those born in 2004/08. CONCLUSION: One in five children had AIDS and one in ten had died. The half of children who received HAART has responded well and survival has significantly improved over time. Earlier diagnosis and prompt initiation of HAART remain key challenges.

RESUMEN

BACKGROUND: Ukraine was the epicentre of the HIV epidemic in Eastern Europe, which has the most rapidly accelerating HIV epidemic world-wide today; national HIV prevalence is currently estimated at 1.6%. Our objective was to evaluate the uptake and effectiveness of interventions for prevention of mother-to-child transmission (PMTCT) over an eight year period within operational settings in Ukraine, within the context of an ongoing birth cohort study. METHODS: The European Collaborative Study (ECS) is an ongoing birth cohort study in which HIV-infected pregnant women identified before or during pregnancy or at delivery were enrolled and their infants prospectively followed. Three centres in Ukraine started enrolling in 2000, with a further three joining in September 2006. RESULTS: Of the 3356 women enrolled, 21% (689) reported current or past injecting drug use (IDU). Most women were diagnosed antenatally and of those, the proportion diagnosed in the first/second trimester increased from 47% in 2000/01 (83/178) to 73% (776/1060) in 2006/07 (p < 0.001); intrapartum diagnosis was associated with IDU (Adjusted odds ratio 4.38; 95%CI 3.19-6.02). The percentage of women not receiving any antiretroviral prophylaxis declined from 18% (36/205) in 2001 to 7% in 2007 (61/843) (p < 0.001). Use of sdNVP alone substantially declined after 2003, with a concomitant increase in zidovudine prophylaxis. Median antenatal zidovudine prophylaxis duration increased from 24 to 72 days between 2000 and 2007. Elective caesarean section (CS) rates were relatively stable over time and 34% overall. Mother-to-child transmission (MTCT) rates decreased from 15.2% in 2001 (95%CI 10.2-21.4) to 7.0% in 2006 (95%CI 2.6-14.6). In adjusted analysis, MTCT risk was reduced by 43% with elective CS versus vaginal delivery and by 75% with zidovudine versus no prophylaxis. CONCLUSION: There have been substantial improvements in use of PMTCT interventions in Ukraine, including earlier diagnosis of HIV-infected pregnant women and increasing coverage with antiretroviral prophylaxis and the initial MTCT rate has more than halved. Future research should focus on hard-to-reach populations such as IDU and on missed opportunities for further reducing the MTCT rate.

RESUMEN

Background: Ukraine's perinatally HIV-infected (PHIV) young people are ageing into adolescence/young adulthood and, alongside those with horizontally-acquired HIV infections, require transitional and other support services. We aimed to map this population and policies/service provision at specialist HIV centres, to inform future service development. Methods: A national survey was conducted of 28 HIV/AIDS centres on number, characteristics (age group, HIV acquisition mode) and care setting (paediatric/adult) of 10-24 year olds in HIV care in each of 24 regions in January 2016. Information was collected on policies/service provision at each centre. Results: Of 13,286 young people aged 10-24 years registered for HIV care nationally in Ukraine in January 2016, 1,675 were aged 10-18 years. Three-quarters of ≤19 year olds were PHIV, while 72% of 20-24-year-olds had sexually-acquired infection. Five regions accounted for two-thirds of 10-18 year olds in paediatric and 85% of 19-24 year olds in adult services. In 2015, 97 young people transitioned from paediatric to adult services nationally, typically at 18 years although with flexibility in timing at 17/28 centres. At 27/28 centres, horizontally HIV-infected young people aged <18 years began their HIV care in paediatric services sometimes (5) or always (22). Transition support most commonly consisted of a joint appointment with paediatrician and adult doctor, and support from a psychologist/social worker (both at 24/28 centres). Only 5/28 centres offered routine HIV care during the evening or weekend, and availability of integrated sexual/reproductive health and harm reduction services was uneven. Of 16/28 centres selectively following-up patients who did not attend for care, 15 targeted patients in paediatric services. Conclusions: Heterogeneity in the population and in service availability at the main regional/municipal HIV/AIDS centres has implications for potential structural barriers to HIV care, and development of services for this group.

RESUMEN

BACKGROUND: Ukraine has the second largest European HIV epidemic. This study aimed to describe stigma, demographic and social factors and their association with anxiety among perinatally and behaviourally-HIV-infected (PHIV; BHIV) young people in Kiev and Odessa. METHODS: 104 PHIV and 100 BHIV young people aged 13-25 years completed a confidential tablet-based survey. Survey tools included the Hospital Anxiety and Depression Scale (HADS) (anxiety sub-scale scores of 8-10 indicating mild and ≥11 moderate/severe symptoms in last 7 days), Rosenberg Self-Esteem Scale (RSES) and HIV Stigma Scale (HSS) (short version, composite of disclosure, negative self-image and public attitudes sub-scales). Unadjusted Poisson regression models were fitted to explore factors associated with moderate/severe anxiety symptoms. RESULTS: PHIV and BHIV young people were of median age 15.5 [IQR 13.9-17.1] and 23.0 [21.0-24.3] years, having registered for HIV care a median 12.3 [10.3-14.4] and 0.9 [0.2-2.4] years previously; 97% (97/100) and 66% (65/99) respectively were on ART. Overall 43% (95%CI 36-50%) reported any and 13% (95%CI 9-19%) moderate/severe anxiety symptoms, with no difference by HIV acquisition mode (p = 0.405) or gender (p = 0.700). 42% (75/180) reported history of an emotional health problem for which they had not been referred/attended for care. Moderate/severe anxiety symptoms were associated with HIV-related stigma (prevalence ratio (PR) 1.24 95%CI 1.14-1.34 per HSS unit increase), lower self-esteem (PR 0.83 95%CI 0.78-0.90 per RSES point increase), CD4 ≤350 cells/mm3 (PR 2.29 95%CI 1.06-4.97), having no-one at home who knew the respondent's HIV status (PR 9.15 95%CI 3.40-24.66 vs all know) and, among BHIV, less stable living situation (PR 6.83 95%CI 1.99-23.48 for ≥2 vs no home moves in last 3 years) and history of drug use (PR 4.65 95%CI 1.83-11.85). CONCLUSIONS: Results indicated unmet need for psychosocial support. Further work is needed to explore strategies for mental health support, particularly around disclosure, self-esteem and stigma.

RESUMEN

BACKGROUND: The aim of this study was to describe the experience of pregnant and non-pregnant HIV-infected women regarding fertility and childbearing, with a view to inform policies and practices to improve reproductive outcome. METHODS: A cross-sectional survey collected information on socio-demographic and basic reproductive characteristics of HIV-infected women in Europe. A total of 403 women participated; 121 were pregnant. RESULTS: The median age was 29 years and 84% (228) of women were born in Europe. Overall 68% (275 of 403) had been pregnant at some time. At the time of the survey, 59% (n = 160) of women had no HIV symptoms; severe symptoms were more frequent among non-pregnant than pregnant respondents (36% (65 of 181) versus 5% (4 of 88)). Of the women, 80% reported being in a long-standing relationship; 39% (74 of 190) reported that they became infected by their current partner and, overall, heterosexual infection was reported as the mode of acquisition in 55% (190 of 344). Maternal well-being, no previous live birth and having an uninfected partner were strongly associated with the likelihood of being pregnant. To assess the problems relating to fertility, pregnant and non-pregnant women were considered separately. Overall, 46% of pregnant women reported not using condoms to protect against infection during pregnancy. Of the 60 pregnant women who planned their pregnancies, 10 reported the need for assistance in conceiving: five monitored their ovulation period and five became pregnant through in vitro fertilization. Of 34 non-pregnant women currently trying for a baby, 15 (44%) had done so for more than 18 months. Overall 25 (27%) of 94 women who planned to become pregnant needed reproductive care. CONCLUSIONS: Our results suggest that these days knowledge of HIV infection neither influences the desire for children nor the decisions regarding pregnancy in HIV-infected women living in Europe.

RESUMEN

BACKGROUND: The effect of hepatitis C virus (HCV) coinfection on CD4 T cell recovery in treated HIV-infected children is poorly understood. OBJECTIVE: To compare CD4 T cell recovery in HIV/HCV coinfected children with recovery in HIV monoinfected children. METHOD: We studied 355 HIV monoinfected and 46 HIV/HCV coinfected children receiving antiretroviral therapy (ART) during a median follow-up period of 4.2 years (interquartile range: 2.7-5.3 years). Our dataset came from the Ukraine pediatric HIV Cohort and the HIV/HCV coinfection study within the European Pregnancy and Paediatric HIV Cohort Collaboration. We fitted an asymptotic nonlinear mixed-effects model of CD4 T cell reconstitution to age-standardized CD4 counts in all 401 children and investigated factors predicting the speed and extent of recovery. RESULTS: We found no significant impact of HCV coinfection on either pre-ART or long-term age-adjusted CD4 counts (z scores). However, the rate of increase in CD4 z score was slower in HIV/HCV coinfected children when compared with their monoinfected counterparts (P < 0.001). Both monoinfected and coinfected children starting ART at younger ages had higher pre-ART (P < 0.001) and long-term (P < 0.001) CD4 z scores than those who started when they were older. CONCLUSIONS: HIV/HCV coinfected children receiving ART had slower CD4 T cell recovery than HIV monoinfected children. HIV/HCV coinfection had no impact on pre-ART or long-term CD4 z scores. Early treatment of HIV/HCV coinfected children with ART should be encouraged.

RESUMEN

Effective interventions for the prevention of mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) infection now exist and where these are fully implemented, MTCT rates of 1-2% are achievable. Virtual elimination of HIV in infants by 2010 has therefore been set as a goal for European region. There are, however, many challenges. The eastern European and central Asian countries are facing the fastest growing HIV epidemic in the world with a dramatic increase in numbers of HIV-positive pregnancies and new HIV infected infants. Nevertheless, the prevalence of HIV among pregnant women is still relatively low and the high coverage with antenatal care provide an opportunity to decrease the number of new HIV cases among infants to minimal level. The challenge is to move national strategies for prevention of HIV infection among infants from a disease-focused vertical approach towards effective preventive interventions integrated into mother-child health (MCH) and reproductive health services. The scaling up of prevention interventions among those most at risk and hard-to-reach women are key priority actions. This goes beyond clinical care and needs to include a range of care and protection issues, both in health institutions and in the community. The WHO Regional Office for Europe, together with other UNAIDS co-sponsors, has developed a regional strategic framework for prevention of HIV infection in infants. The strategic framework promotes a comprehensive approach comprising the four interrelated elements: (1) primary prevention of HIV infection; (2) prevention of unintended pregnancies among HIV-infected women; (3) prevention of HIV transmission from HIV-infected women to their children; (4) provision of care and support to HIV-infected women, their infants and families. Implementation of all four pillars of the strategic framework would help European countries to achieve the goal of virtual elimination of HIV infection in infants.
