Pediatric HIV care cascade in southern mozambique: Missed opportunities for early ART and re-engagement in care

© 2020 Wolters Kluwer Health, Inc. All rights reserved. Background: There are 170,000 children living with HIV in 2017 in Mozambique. Scaling-up HIV care requires effective retention along the cascade. We sought to evaluate the pediatric cascade in HIV care at the Manhiça District Hospital. Methods: A prospective cohort of children <15 years was followed from enrollment in HIV care (January 2013 to December 2015) until December 2016. Loss to follow-up (LTFU) was defined as not attending the HIV hospital visits for ≥90 days following last visit attended. Results: From the 438 children included {median age at enrollment in care of 3,6 [interquartile range (IQR): 1.1-8.6] years}, 335 (76%) were antiretroviral therapy (ART) eligible and among those, 263 (78%) started ART at enrollment in HIV care. A total of 362 children initiated ART during the study period and the incidence rate of LTFU at 12, 24, and 36 months post-ART initiation was 41 [95% confidence interval (CI): 34-50], 34 (95% CI: 29-41), and 31 (95% CI: 27-37) per 100 children-years, respectively. Median time to LTFU was 5.8 (IQR: 1.4-12.7) months. Children 5-9 years of age had a lower risk of LTFU compared with children <1 year [adjusted subhazard ratio 0.36 (95% CI: 0.20-0.61)]. Re-engagement in care (RIC) was observed in 25% of the LTFU children. Conclusions: The high LTFU found in this study highlights the special attention that should be given to younger children during the first 6 months post-ART initiation to prevent LTFU. Once LTFU, only a quarter of those children return to the health unit. Elucidating factors associated with RIC could help to fine tune interventions which promote RIC

HPV vaccination introduction worldwide and WHO and UNICEF estimates of national HPV immunization coverage 2010–2019

WHO/UNICEF estimates for HPV vaccination coverage from 2010 to 2019 are analyzed against the backdrop of the 90% coverage target for HPV vaccination by 2030 set in the recently approved global strategy for cervical cancer elimination as a public health problem. As of June 2020, 107 (55%) of the 194 WHO Member States have introduced HPV vaccination. The Americas and Europe are by far the WHO regions with the most introductions, 85% and 77% of their countries having already introduced respectively. A record number of introductions was observed in 2019, most of which in low- and middle- income countries (LMIC) where access has been limited. Programs had an average performance coverage of around 67% for the first dose and 53% for the final dose of HPV. LMICs performed on average better than high- income countries for the first dose, but worse for the last dose due to higher dropout. Only 5 (6%) countries achieved coverages with the final dose of more than 90%, 22 countries (21%) achieved coverages of 75% or higher while 35 (40%) had a final dose coverage of 50% or less. When expressed as world population coverage (i.e., weighted by population size), global coverage of the final HPV dose for 2019 is estimated at 15%. There is a long way to go to meet the 2030 elimination target of 90%. In the post-COVID era attention should be paid to maintain the pace of introductions, specially ensuring the most populous countries introduce, and further improving program performance globally

Uncovering HIV and malaria interactions: the latest evidence and knowledge gaps

The geographical distribution of malaria and HIV infections widely overlap in sub-Saharan Africa, constituting a complex global health challenge. The interplay between both infections raises concerns about potential immunological, clinical, and therapeutic interactions. Both diseases have been reported to exacerbate the transmission of the other, including the possible vertical transmission of HIV in pregnant individuals with malaria. Co-infection also increases the risk of adverse outcomes such as severe malaria and death. In addition, interactions between antiretroviral and antimalarial drugs have been reported, potentially reducing the efficacy of these drugs. We review the current knowledge of the epidemiological, clinical, immunological, and therapeutic interactions of both infections. We focus on the latest available data and identify key knowledge gaps that should be addressed to guide policy makers in providing optimal HIV and malaria prevention, care, and treatment in vulnerable populations

Field performance and cost‐effectiveness of a point‐of‐care triage test for HIV virological failure in Southern Africa

Abstract Introduction Antiretroviral therapy (ART) monitoring using viral load (VL) testing is challenging in high‐burden, limited‐resources settings. Chemokine IP‐10 (interferon gamma‐induced protein 10) strongly correlates with human immunodeficiency virus (HIV) VL. Its determination could serve to predict virological failure (VF) and to triage patients requiring VL testing. We assessed the field performance of a semi‐quantitative IP‐10 lateral flow assay (LFA) for VF screening in South Africa, and the cost‐effectiveness of its implementation in Mozambique. Methods A cross‐sectional study was conducted between June and December 2021 in three primary health clinics in the Western Cape. Finger prick capillary blood was collected from adults on ART for ≥1 year for direct application onto the IP‐10 LFA (index test) and compared with a plasma VL result ≤1 month prior (reference test). We estimated the area under the receiver operating characteristic curves (AUC), sensitivity and specificity, to evaluate IP‐10 LFA prediction of VF (VL>1000 copies/ml). A decision tree model was used to investigate the cost‐effectiveness of integrating IP‐10 LFA combined with VL testing into the current Mozambican ART monitoring strategy. Averted disability‐adjusted life years (DALYs) and HIV acquisitions, and incremental cost‐effectiveness ratios were estimated. Results Among 209 participants (median age 38 years and 84% female), 18% had VF. Median IP‐10 LFA values were higher among individuals with VF compared to those without (24.0 vs. 14.6; p<0.001). The IP‐10 LFA predicted VF with an AUC = 0.76 (95% confidence interval (CI) 0.67–0.85), 91.9% sensitivity (95% CI 78.1–98.3) and 35.1% specificity (95% CI 28.0–42.7). Integrating the IP‐10 LFA in a setting with 20% VF prevalence and 61% VL testing coverage could save 13.0% of costs and avert 14.9% of DALYs and 55.7% new HIV acquisitions. Furthermore, its introduction was estimated to reduce the total number of routine VL tests required for ART monitoring by up to 68%. Conclusions The IP‐10 LFA is an effective VF triage test for routine ART monitoring. Combining a highly sensitive, low‐cost IP‐10 LFA‐based screening with targeted VL confirmatory testing could result in significant healthcare quality improvements and cost savings in settings with limited access to VL testing

COVID-19 among workers of a comprehensive cancer centre between first and second epidemic waves (2020): a seroprevalence study in Catalonia, Spain

Objectives Patients with cancer are at higher risk for severe COVID-19 infection. COVID-19 surveillance of workers in oncological centres is crucial to assess infection burden and prevent transmission. We estimate the SARS-CoV-2 seroprevalence among healthcare workers (HCWs) of a comprehensive cancer centre in Catalonia, Spain, and analyse its association with sociodemographic characteristics, exposure factors and behaviours. Design Cross-sectional study (21 May 2020-26 June 2020). Setting A comprehensive cancer centre (Institut Catala d'Oncologia) in Catalonia, Spain. Participants All HCWs (N=1969) were invited to complete an online self-administered epidemiological survey and provide a blood sample for SARS-CoV-2 antibodies detection. Primary outcome measure Prevalence (%) and 95% CIs of seropositivity together with adjusted prevalence ratios (aPR) and 95% CI were estimated. Results A total of 1266 HCWs filled the survey (participation rate: 64.0%) and 1238 underwent serological testing (97.8%). The median age was 43.7 years (p25-p75: 34.8-51.0 years), 76.0% were female, 52.0% were nursing or medical staff and 79.0% worked on-site during the pandemic period. SARS-CoV-2 seroprevalence was 8.9% (95% CI 7.44% to 10.63%), with no differences by age and sex. No significant differences in terms of seroprevalence were observed between onsite workers and teleworkers. Seropositivity was associated with living with a person with COVID-19 (aPR 3.86, 95% CI 2.49 to 5.98). Among on-site workers, seropositive participants were twofold more likely to be nursing or medical staff. Nursing and medical staff working in a COVID-19 area showed a higher seroprevalence than other staff (aPR 2.45, 95% CI 1.08 to 5.52). Conclusions At the end of the first wave of the pandemic in Spain, SARS-CoV-2 seroprevalence among Institut Catala d'Oncologia HCW was lower than the reported in other Spanish hospitals. The main risk factors were sharing household with infected people and contact with COVID-19 patients and colleagues. Strengthening preventive measures and health education among HCW is fundamental
