Malaria Parasitemia and Nutritional Status during the Low Transmission Season in the Presence of Azithromycin Distribution among Preschool Children in Niger

The Association between Malnutrition and Malaria Infection in Children under 5 Years in Burkina Faso: A Longitudinal Study

The relationship between malaria infection and malnutrition is complex. Using data from a randomized controlled trial of 450 children 0-5 years of age in Burkina Faso, we examined the effect of malaria infection on short-term changes in anthropometric measures, the effect of malnutrition on malaria infection, and whether age modified the effect of baseline anthropometric measures on malaria infection. Malaria infection, assessed by blood smear microscopy and weight, height, mid-upper arm circumference, height-for-age z-score, weight-for-age z-score, and weight-for-height z-score were measured at three time points: baseline, 2 weeks, and 6 months. We used generalized estimating equations adjusted for sex, age, breastfeeding, maternal education, and study treatment (azithromycin versus placebo) for all analyses. Interaction terms were used to assess effect modification by age. Among the 366 children with no malaria infection at baseline, 43 (11.6%) had malaria infection within 6 months. There were no important differences in anthropometric measures at 2 weeks and 6 months between those with and without malaria infection at baseline. There were no significant differences in prevalence of malaria infection by baseline anthropometric measures. Age (0-30 months versus 30-60 months) modified the effect of baseline weight and height on malaria infection. Among those aged 0-30 months, for each kilogram increase in weight, malaria infection increased by 27% (95% CI: 6-53%), and for each centimeter increase in height, it increased by 9% (95% CI: 1-17%), but there were no differences for those aged 30-60 months.

Azithromycin versus Amoxicillin and Malarial Parasitemia among Children with Uncomplicated Severe Acute Malnutrition: A Randomized Controlled Trial

Antibiotics are recommended by the WHO as part of the management of uncomplicated severe acute malnutrition in children. We evaluated whether azithromycin, an antibiotic with antimalarial properties, improved malarial parasitemia outcomes in children with severe acute malnutrition compared with amoxicillin, an antibiotic commonly used for severe acute malnutrition that does not have antimalarial properties. Total of 301 children were randomized (1:1) to a single oral dose of azithromycin or a 7-day course of amoxicillin and followed for 8 weeks. We found no significant evidence that children receiving azithromycin had improved parasitemia outcomes relative to amoxicillin. Although azithromycin may have advantages over amoxicillin in terms of dosing and administration for uncomplicated severe acute malnutrition, it may not yield additional benefit for malaria outcomes.

Impact of mass and systematic antibiotic administration on antibiotic resistance in low- and middle-income countries? A systematic review

Antibiotic consumption is a key driver of antimicrobial resistance (AR), particularly in low- and middle-income countries (LMICs) where risk factors for AR emergence and spread are prevalent. However, the potential contribution of mass drug administration (MDA) and systematic drug administration (SDA) of antibiotics to AR spread is unknown. We conducted a systematic review to provide an overview of MDA/SDA in LMICs, including indications, antibiotics used and, if investigated, levels of AR over time. This systematic review is reported in accordance with the PRISMA statement. Of 2438 identified articles, 63 were reviewed: indications for MDA/SDA were various, and targeted populations were particularly vulnerable, including pregnant women, children, human immunodeficiency virus (HIV)-infected populations, and communities in outbreak settings. Available data suggest that MDA/SDA may lead to a significant increase in AR, especially following azithromycin administration. However, only 40% of studies evaluated AR. Integrative approaches that evaluate AR in addition to clinical outcomes are needed to understand the consequences of MDA/SDA implementation, combined with standardised AR surveillance for timely detection of AR emergence.

Undernutrition and malaria among under-five children: findings from the 2018 Nigeria demographic and health survey

Malaria and undernutrition have independently contributed to mortality and morbidity among the under-five population of Nigeria. However, there remains complexity in their association. This study evaluates the association between stunting, underweight, wasting, and malaria among under-five Nigerian children while assessing the effects of sociodemographic factors. Cross-sectional data from the 2018 Nigeria Demographic and Health Survey were used, which included a study population of 12,996 children aged 0-59 months. Stunting (HAZ<-2.0 SD), underweight (WAZ<-2.0 SD), wasting (WHZ<-2.0 SD), malaria test results, and sociodemographic factors were obtained and examined. Logistic regression modeling was used to determine the associations between undernutrition, malaria, and sociodemographic factors. The prevalence of stunting was 37.0%, with 22.0% underweight, 6.9% wasting, and 22.6% tested positive for malaria. Stunting was frequent among 24-35 months old, 12-23 months old were mostly underweight and wasted, and 48-59 months old frequently suffered from malaria. Undernutrition and malaria frequently occurred among males, residents of rural areas, the poorest wealth quintile, and children of mothers with no formal education. The odds of having malaria was 89% higher among under-five stunted children (AOR = 1.89, 95% CI = 1.00,1.40; p-value = <0.0001). However, underweight (AOR = 1.11, 95% CI = 0.91,1.36; p-value = 0.2982) and wasting (AOR = 0.89, 95% CI = 0.67,1.19; p-value = 0.4519) were not significantly associated with malaria. The development of appropriate strategies, especially in rural areas and for less-educated mothers are critical to combat undernutrition and malaria.
