RESUMEN

Viral suppression (VS) in children has remained suboptimal compared to that in adults. We evaluated the impact of transitioning children weighing < 20 kg to a pediatric formulation of dolutegravir (pDTG) on VS in Malawi. We analyzed routine retrospective program data from electronic medical record systems pooled across 169 healthcare facilities in Malawi supported by the Elizabeth Glaser Pediatric AIDS Foundation (EGPAF). We included children who weighed < 20 kg and received antiretroviral therapy (ART) between July 2021-June 2022. Using descriptive statistics, we summarized demographic and clinical characteristics, ART regimens, ART adherence, and VS. We used logistic regression to identify factors associated with post-transition VS. A total of 2468 Children Living with HIV (CLHIV) were included, 55.3% of whom were < 60 months old. Most (83.8%) had initiated on non-DTG-based ART; 71.0% of these had a viral load (VL) test result before transitioning to pDTG, and 62.5% had VS. Nearly all (99.9%) CLHIV transitioned to pDTG-based regimens. Six months after the transition, 52.7% had good ART adherence, and 38.6% had routine VL testing results; 81.7% achieved VS. Post-transition VS was associated with good adherence and pre-transition VS: adjusted odds ratios of 2.79 (95% CI 1.65-4.71), p < 0.001 and 5.32 (95% CI 3.23-9.48), p < 0.001, respectively. After transitioning to pDTG, VS was achieved in most children tested within the first 6 months. However, adherence remained suboptimal post-transition and VL testing at 6 months was limited. Interventions to improve VL testing and enhance ART adherence are still needed in CLHIV on pDTG-based regimens.

RESUMEN

BACKGROUND: The introduction of dolutegravir (DTG) in treating HIV has shown enhanced efficacy and tolerability. This study examined changes in weight gain and body mass index (BMI) at 6- and 12-months after post-initiating antiretroviral therapy (ART), comparing people living with HIV (PLHIV) on DTG-based regimens with those on non-DTG-based regimens in Malawi. METHODS: Retrospective cohort data from 40 public health facilities in Malawi were used, including adult ART patients (aged ≥ 15 years) from January 2017 to March 2020. The primary outcomes were BMI changes/transitions, with secondary outcomes focused on estimating the proportion of mean weight gain > 10% post-ART initiation and BMI category transitions. Descriptive statistics and binomial regression were used to estimate the unadjusted and adjusted relative risks (RR) of weight gain of more than ( >) 10%. RESULTS: The study included 3,520 adult ART patients with baseline weight after ART initiation, predominantly female (62.7%) and aged 25-49 (61.1%), with a median age of 33 years (interquartile range (IQR), 23-42 years). These findings highlight the influence of age, ART history, and current regimen on weight gain. After 12months follow up, compared to those aged 15-24 years, individuals aged 25-49 had an Adjusted RR (ARR) of 0.5 (95% Confidence Interval (CI): 0.35-0.70), suggesting a 50% reduced likelihood of > 10% weight gain after post-ART initiation. Similarly, those aged 50 + had an ARR of 0.33 (95% CI: 0.20-0.58), indicating a 67% decreased likelihood compared to the youngest age group 15-24 years. This study highlights the positive impact of DTG-based regimens, revealing significant transitions from underweight to normal BMI categories at 6- and 12-months post-initiation. CONCLUSION: This study provides insights into weight gain patterns in patients on DTG-based regimens compared with those on non-DTG regimens. Younger individuals (15-24 years) exhibited higher odds of weight gain, suggesting a need for increased surveillance in this age group. These findings contribute to the understanding DTG's potential effects on weight gain, aiding clinical decision making. Further research is required to comprehensively understand the underlying mechanisms and long-term implications of weight gain in patients receiving DTG-based regimens.

RESUMEN

The global disruption caused by the SARS-CoV-2 pandemic profoundly affected healthcare systems, particularly impacting People Living with Human Immunodeficiency Virus (PLHIV). This study investigated the repercussions of SARS-CoV-2 infection on access to human immunodeficiency virus (HIV) care and antiretroviral therapy (ARV) in Malawi, emphasizing the critical need to sustain uninterrupted HIV services during health crises. Employing mobile phone-based syndromic surveillance, this study assessed the influence of SARS-CoV-2 on healthcare access for PLHIV across nine districts supported by the Elizabeth Glaser Pediatric AIDS Foundation (EGPAF). Telephone-based interviews were conducted to analyze demographic factors, challenges encountered in accessing HIV services, and adherence to ARV medication, illuminating the pandemic's effects on ARV uptake. The findings revealed that approximately 3.9% (n = 852) of 21981 participants faced obstacles in accessing crucial HIV services during the pandemic, resulting in approximately 1.2% (n = 270) reporting multiple missed doses of ARV medication in a particular month. After adjusting for various variables, males exhibited a higher likelihood of service inaccessibility than females (Adjusted Odds Ratio [AOR] = 1.39, 95% CI: 1.20-1.60, p < 0.001). Age also played a significant role, with individuals aged 35-49 years and those aged 50 years or older demonstrating reduced odds of service failure compared with the reference group aged 18-34 years. Only a small proportion of PLHIV reported disruption in HIV care access, which may be because Malawi did not initiate stringent travel restrictions during the SARS-CoV-2 pandemic. Nonetheless, enduring challenges have been observed in retaining younger PLHIV and men in HIV-care settings. Thus, targeted strategies are imperative for effectively engaging and sustaining these populations in HIV care during and after health crises.

RESUMEN

Malawi recommended COVID-19 vaccines for adults aged ≥18 years in March 2021. We assessed factors associated with receiving COVID-19 vaccines in Malawi as part of a telephone-based syndromic surveillance survey. We conducted telephone-based syndromic surveillance surveys with questions on COVID-19 vaccine receipt among adults (≥18 years old) upon verbal consent from July 2021 to April 2022. We used random digit dialing to select mobile phone numbers and employed electronic data collection forms on secure tablets. Survey questions included whether the respondent had received at least one dose of a COVID-19 vaccine. We used multivariable analysis to identify factors associated with COVID-19 vaccine receipt. Of the 51,577 participants enrolled; 65.7% were male. Males were less likely to receive the COVID-19 vaccine than females (AOR 0.83, 95% CI 0.80-0.86). Compared to those aged 18-24 years, older age had increased odds of vaccine receipt: 25-34 years (AOR 1.32, 95% CI 1.24-1.40), 35-44 years (AOR 2.00, 95% CI 1.88-2.13), 45-54 years (AOR 3.02, 95% CI 2.82-3.24), 55-64 years (AOR 3.24, 95% CI 2.93-3.57) and 65 years+ (AOR 3.98, 95% CI 3.52-4.49). Respondents without formal education were less likely to receive vaccination compared to those with primary (AOR 1.30, 95% CI 1.14-1.48), secondary (AOR 1.76, 95% CI 1.55-2.01), and tertiary (AOR 3.37, 95% CI 2.95-3.86) education. Respondents who thought COVID-19 vaccines were unsafe were less likely to receive vaccination than those who thought it was very safe (AOR 0.26, 95% CI 0.25-0.28). Residents of the Central and Southern regions had reduced odds of vaccine receipt compared to those in the North (AORs 0.79, (95% CI 0.74-0.84) and 0.55, (95% CI 0.52-0.58) respectively). Radio (72.6%), health facilities (52.1%), and social media (16.0%) were the more common self-reported sources of COVID-19 vaccine information. COVID-19 vaccine receipt is associated with gender, age, education, and residence. It is important to consider these factors when implementing COVID-19 vaccination programs.

RESUMEN

INTRODUCTION: Monitoring the SARS-CoV-2 pandemic in low-resource countries such as Malawi requires cost-effective surveillance strategies. This study explored the potential utility of phone-based syndromic surveillance in terms of its reach, monitoring trends in reported SARS-CoV-2-like/influenza-like symptoms (CLS/ILS), SARS-CoV-2 testing and mortality. METHODS: Mobile phone-based interviews were conducted between 1 July 2020 and 30 April 2022, using a structured questionnaire. Randomly digital dialled numbers were used to reach individuals aged ≥18 years who spoke Chichewa or English. Verbal consent was obtained, and trained research assistants with clinical and nursing backgrounds collected information on age, sex, region of residence, reported CLS/ILS in the preceding 2 weeks, SARS-CoV-2 testing and history of household illness and death. Data were captured on tablets using the Open Data Kit database. We performed a descriptive analysis and presented the frequencies and proportions with graphical representations over time. FINDINGS: Among 356 525 active phone numbers, 138 751 (38.9%) answered calls, of which 104 360 (75.2%) were eligible, 101 617 (97.4%) consented to participate, and 100 160 (98.6%) completed the interview. Most survey respondents were aged 25-54 years (72.7%) and male (65.1%). The regional distribution of the respondents mirrored the regional population distribution, with 45% (44%) in the southern region, 41% (43%) in the central region and 14% (13%) in the northern region. The reported SARS-CoV2 positivity rate was 11.5% (107/934). Of the 7298 patients who reported CLS/ILS, 934 (12.8%) reported having undergone COVID-19 testing. Of the reported household deaths, 47.2% (982 individuals) experienced CLS/ILS 2 weeks before their death. CONCLUSION: Telephonic surveillance indicated that the number of SARS-CoV-2 cases was at least twice as high as the number of confirmed cases in Malawi. Our findings also suggest a substantial under-reporting of SARS-CoV-2-related deaths. Telephonic surveillance has proven feasible in Malawi, achieving the ability to characterise SARS-CoV-2 morbidity and mortality trends in low-resource settings.

RESUMEN

The safety profiles of the Ad26.COV2.S and AZD1222 COVID-19 vaccines have not been described in the general population in Malawi. We present self-reported adverse events (AE) following the receipt of these vaccines in Malawi as part of a national syndromic surveillance survey. We conducted phone-based syndromic surveillance surveys among adults (≥18 years) with verbal consent. We used secure tablets through random digit dialing to select mobile phone numbers and collected data electronically. Survey questions included whether the respondent had received the COVID-19 vaccines, whether they had experienced any AE following vaccination, and the severity of the AE. We used multivariable analysis to identify factors associated with self-reported AE post-COVID-19 vaccination. A total of 11,924 (36.0%) out of 33,150 respondents reported receiving at least one dose of either Ad26.COV2.S or AZD1222 between July-December 2021; of those, 65.1% were female. About 49.2% of the vaccine recipients reported at least one AE, 90.6% of which were mild, and 2.6% were severe. Higher education level and concern about the safety of COVID-19 vaccines were associated with AE self-report (Adjusted Odds Ratio [AOR] 2.63 [95% CI 1.96-3.53] and 1.44, [95% CI 1.30-1.61], respectively), while male gender and older age were associated with reduced likelihood of AE self-report (AORs 0.81, [95% CI 0.75-0.88], 0.62 [95% CI 0.50-0.77], respectively). Ad26.COV2.S and AZD1222 vaccines are well-tolerated, with primarily mild and few severe AE among adults living in Malawi. Self-reporting of AE following COVID-19 vaccination is associated with gender, age, education, and concern about the safety of the vaccines. Recognizing these associations is key when designing and implementing COVID-19 vaccination communication messages to increase vaccination coverage.
