RESUMEN

Globally, children aged <5 years, including those living with HIV who are not receiving antiretroviral treatment (ART), experience disproportionately high mortality. Global mortality among children living with HIV aged <5 years receiving ART is not well described. This report compares mortality and related clinical measures among infants aged <1 year and children aged 1-4 years living with HIV with those among older persons aged 5-14, 15-49, and ≥50 years living with HIV receiving ART services at all clinical sites supported by the U.S. President's Emergency Plan for AIDS Relief. During October 2020-September 2022, an average of 11,980 infants aged <1 year and 105,510 children aged 1-4 years were receiving ART each quarter; among these infants and children receiving ART, 586 (4.9%) and 2,684 (2.5%), respectively, were reported to have died annually. These proportions of infants and children who died ranged from four to nine times higher in infants aged <1 year, and two to five times higher in children aged 1-4 years, than the proportions of older persons aged ≥5 years receiving ART. Compared with persons aged ≥5 years living with HIV, the proportions of children aged <5 years living with HIV who experienced interruptions in treatment were also higher, and the proportions who had a documented HIV viral load result or a suppressed viral load were lower. Prioritizing and optimizing HIV and general health services for children aged <5 years living with HIV receiving ART, including those recommended in the WHO STOP AIDS Package, might help address these disproportionately poorer outcomes.

RESUMEN

The WHO Global Health Sector Strategy and hepatitis regional action plan for the WHO Eastern Mediterranean Region (EMR) proposed strategic directions for countries to progress towards the elimination of viral hepatitis by 2030. In 2019, we reviewed progress to gain a picture of current pressures and identify priority actions for member states to reach this goal. We collected data from country, regional, and global reports published in 2015-19, questionnaires completed by countries, and convened a regional consultation with programme managers and partners. We analysed these data along three thematic areas: governance and finance, strategic information, and service delivery. 15 of the 22 EMR countries completed the review. Of these, 10 (67%) had a national strategy and six (40%) allocated funds to it. 11 (73%) countries had testing and treatment guidelines in line with WHO recommendations. Ten (67%) countries had burden and coverage estimates, four (27%) reported on the cascade of care for hepatitis C virus (HCV), three (20%) reported on the cascade of care for hepatitis B (HBV), and three (20%) had mortality estimates. By 2019, the regional hepatitis B vaccination coverage among infants was 82% for the third dose and 33% for the timely birth dose. For harm reduction, 27 syringes were distributed per injecting drug user per year. Between 2015 and 2019, HCV diagnosis increased from 18% to 33% and treatment for hepatitis C increased from 12% to 26%. Within the same time period, diagnosis of HBV diagnosis increased from 2% to 14% and treatment initiation increased from less than 1% to 2%. EMR countries made progress in governance, policy development, coverage of the third dose of the hepatitis B vaccine, and testing and treatment for HCV infection. However, birth dose vaccination, injection safety, harm reduction, and testing and treatment are limited by insufficient financing. Core interventions need to be included within national universal health coverage packages as an initial move towards elimination.

RESUMEN

BACKGROUND: Worldwide, HIV incidence, and mortality has decreased since 2010; however, in the WHO Eastern Mediterranean region, trends continue to increase. We reviewed the regional progress to understand determinants of this situation and inform strategies to accelerate the response. METHODS: We conducted a multicountry programme review of 22 countries in the WHO Eastern Mediterranean region from Jan 1, 2010 to Dec 31, 2020. We extracted data from WHO's global AIDS monitoring system, UNAIDS estimates, and country reports regarding incident cases, policy uptake, and antiretrovirals used. We analysed data to describe incidence, testing practices, treatment coverage, and mortality to identify bottlenecks leading to persisting incidence and mortality. FINDINGS: Due to COVID-19 disruptions, the volume of HIV testing in 2020 halved to 3·0 million tests compared with 2019 with 8017 people living with HIV identified (0·27% positivity yield). In comparison with a 0·18% positivity yield from the 6·5 million tests in 2019. HIV tests were done in migrants (59·6%), groups at low risk (38·9%), and key populations (1·5%). Diagnoses with advanced disease increased from 27·3% in 2017 to 37·0% in 2019. In 2019, among 52 318 people on treatment, only 2888 (6%) received optimised regimens as per WHO recommendations. The number of people on treatment increased from 19 000 in 2010 with a coverage of 8% to 110 000 in 2020 with a coverage of 25%. Late diagnoses and suboptimal regimens could explain the increase in mortality from 9600 in 2010 to 17 000 in 2020. INTERPRETATION: In the Eastern Mediterranean region, inefficient testing and suboptimal treatment lead to underdiagnosis, persisting transmission, late treatment, and rising mortality. The HIV epidemic is growing faster than the response. A change in thinking is needed to test groups at high risk, transition to optimised treatment, and deliver patient-centred services that maximise retention. FUNDING: World Health Organization.

RESUMEN

Early on in the COVID-19 pandemic, the WHO Eastern Mediterranean Regional Office recognised the importance of epidemiological modelling to forecast the progression of the COVID-19 pandemic to support decisions guiding the implementation of response measures. We established a modelling support team to facilitate the application of epidemiological modelling analyses in the Eastern Mediterranean Region (EMR) countries. Here, we present an innovative, stepwise approach to participatory modelling of the COVID-19 pandemic that engaged decision-makers and public health professionals from countries throughout all stages of the modelling process. Our approach consisted of first identifying the relevant policy questions, collecting country-specific data and interpreting model findings from a decision-maker's perspective, as well as communicating model uncertainty. We used a simple modelling methodology that was adaptable to the shortage of epidemiological data, and the limited modelling capacity, in our region. We discuss the benefits of using models to produce rapid decision-making guidance for COVID-19 control in the WHO EMR, as well as challenges that we have experienced regarding conveying uncertainty associated with model results, synthesising and comparing results across multiple modelling approaches, and modelling fragile and conflict-affected states.

RESUMEN

Pediatric human immunodeficiency virus (HIV) infection remains an important public health issue in resource-limited settings. In 2015, 1.4 million children aged <15 years were estimated to be living with HIV (including 170,000 infants born in 2015), with the vast majority living in sub-Saharan Africa (1). In 2014, 150,000 children died from HIV-related causes worldwide (2). Access to timely HIV diagnosis and treatment for HIV-infected infants reduces HIV-associated mortality, which is approximately 50% by age 2 years without treatment (3). Since 2011, the annual number of HIV-infected children has declined by 50%. Despite this gain, in 2014, only 42% of HIV-exposed infants received a diagnostic test for HIV (2), and in 2015, only 51% of children living with HIV received antiretroviral therapy (1). Access to services for early infant diagnosis of HIV (which includes access to testing for HIV-exposed infants and clinical diagnosis of HIV-infected infants) is critical for reducing HIV-associated mortality in children aged <15 years. Using data collected from seven countries supported by the U.S. President's Emergency Plan for AIDS Relief (PEPFAR), progress in the provision of HIV testing services for early infant diagnosis was assessed. During 2011-2015, the total number of HIV diagnostic tests performed among HIV-exposed infants within 6 weeks after birth (tests for early infant diagnosis of HIV), as recommended by the World Health Organization (WHO) increased in all seven countries (Cote d'Ivoire, the Democratic Republic of the Congo, Haiti, Malawi, South Africa, Uganda, and Zambia); however, in 2015, the rate of testing for early infant diagnosis among HIV-exposed infants was <50% in five countries. HIV positivity among those tested declined in all seven countries, with three countries (Cote d'Ivoire, the Democratic Republic of the Congo, and Uganda) reporting >50% decline. The most common challenges for access to testing for early infant diagnosis included difficulties in specimen transport, long turnaround time between specimen collection and receipt of results, and limitations in supply chain management. Further reductions in HIV mortality in children can be achieved through continued expansion and improvement of services for early infant diagnosis in PEPFAR-supported countries, including initiatives targeted to reach HIV-exposed infants, ensure access to programs for early infant diagnosis of HIV, and facilitate prompt linkage to treatment for children diagnosed with HIV infection.

RESUMEN

Neonatal male circumcision (NMC) is an uncommon procedure in Southern Africa, but is being scaled up in Zambia for long-term HIV prevention. We conducted a cross-sectional survey on NMC with a convenience sample of mothers of newborn boys at two public clinics in Lusaka. Following the survey, mothers received information on availability of NMC, and uptake of the service was tracked. Predictors of uptake were assessed using bivariate and multivariate logistic regression. Of the 1,249 eligible mothers approached, 1000 (80%) agreed to participate. Although 97% of surveyed mothers said they definitely or probably planned to have their newborn son circumcised, only 11% of participants brought their newborn sons for NMC. Significant predictors of uptake in adjusted models included: Older maternal age (AOR 3.77, 95% CI 1.48-9.63 for age 36 and above compared to mothers age 25 and below), having attended antenatal care at an NMC site (AOR 2.13, 95% CI 1.32-3.44), older paternal age (AOR 4.36, 95% CI 1.28-14.91 for age 26-35 compared to fathers age 25 and below), and the infant's father being circumcised (AOR 2.21, 95% CI 1.35-3.62). While acceptability studies in Southern Africa have suggested strong support for MC among parents for having their sons circumcised, this may not translate to high uptake of newly-introduced NMC services.

RESUMEN

OBJECTIVE: Neonatal male circumcision (NMC) is not routinely practiced in Zambia, but it is a promising long-term HIV prevention strategy. We studied the feasibility and safety of three different NMC methods. METHODS: We enrolled healthy newborns in a controlled trial of the Mogen, Gomco, and Plastibell devices. Doctors, nurses, and clinical officers were trained to perform Mogen, Gomco, and Plastibell techniques. Each provider performed at least 10 circumcisions using each device. Neonates were reviewed at 1 and 6 weeks after circumcision for adverse events. RESULTS: Between October 2009 and March 2011, 17 providers (5 physicians, 9 nurse midwives, and 3 clinical officers) without previous NMC experience were trained, and 640 circumcisions were performed. The median infant birth weight was 3.2 kg (interquartile range: 2.9-3.5 kg), and median age at the time of procedure was 11 days (interquartile range: 7-18 days); 149 babies (23.3%) were exposed to HIV. The overall adverse event rate was 4.9% (n = 31/630), and the moderate-severe adverse event rate was 4.1% (n = 26/630). Rates did not significantly differ by method. Most providers (65%) preferred Mogen clamp over Gomco and Plastibell. CONCLUSIONS: Doctors, nurses, and clinical officers can be trained to safely provide NMC in a programmatic setting. The 3 studied techniques had comparable safety profiles. Mogen clamp was the preferred device for most providers.

RESUMEN

Neonatal male circumcision (NMC) is being scaled up in Zambia and elsewhere in Southern Africa as a long-term HIV prevention strategy. We conducted 12 focus group discussions with 129 parents and grandparents in Lusaka, recruited from two sites providing free NMC services and information about NMC, to explore the acceptability of circumcising newborn boys. Most participants recognized the benefits of circumcision for HIV prevention, and the advantages of circumcising their children and grandchildren at a young age. Fear of negative outcomes, concerns about pain, and issues around cultural identity may challenge NMC uptake. To effectively promote the service, the upper age limit for NMC must be emphasized, and fathers must be targeted by messaging campaigns.
