The DECIDE-TB Trial; Validation of Treatment Decision Algorithms for Childhood Tuberculosis

The Decide-TB project aims to generate evidence for the implementation of a comprehensive Treatment Decision Algorithms (TDA) based approach for TB in children living in high TB burden and resource-limited countries, at District Hospital (DH) and Primary Health Centre (PHC) levels, and to facilitate the integration of this evidence within practices and policies. This programmatic pilot led by the National TB Programs (NTP) will test a TDA-based approach integrating TB screening, diagnosis, treatment decision-making, and disease severity assessment for shorter treatment eligibility, for use at a lower level of healthcare. This TDA-based approach will be evaluated in a hybrid effectiveness implementation study based on a pragmatic stepped wedge cluster-randomized trial. The Decide TB project will be implemented at the district level, targeting five districts in each country. Each cluster in a district will be made up of one district hospital and six primary health centers. The study will develop a Clinical Decision Support System (CDSS) to operationalize the use of TDAs, and strengthen District Health Information Systems (DHIS2) to collect individual data, which will contribute to monitoring and evaluation, clinical mentoring, and supervision by the country's NTPs.

An Adaptive Multi-arm Trial to Improve Clinical Outcomes Among Children Recovering From Complicated SAM

Malnutrition underlies 45% of child deaths, and has far-reaching educational, economic and health consequences. Severe acute malnutrition (SAM) affects 17 million children globally and is the most life-threatening form of malnutrition. Community-based management of acute malnutrition using ready-to-use therapeutic food (RUTF) has transformed outcomes for children with uncomplicated SAM, but those presenting with poor appetite or medical complications (categorised as having 'complicated' SAM) require hospitalisation. Data show that pneumonia, diarrhoea and malaria are leading causes of death in children with complicated SAM after discharge from hospital. High risk of infectious deaths suggests that sustained antimicrobial interventions may reduce mortality following discharge from hospital. Furthermore, children with complicated SAM respond less well to nutritional rehabilitation, and oftentimes are discharged to a home environment characterised by poverty and multiple caregiver vulnerabilities including depression, low decision making autonomy, lack of social support, gender-restricted family relations, and competing demands on scarce resources. Caregivers have to navigate diverse challenges that impede engagement with clinical care after discharge from hospital. The objective is to address the biological and social determinants of multimorbidity in children with complicated SAM by comparing an antimicrobial intervention with standard of care.

Choline to Improve Malnutrition and Enhance Cognition

The goal of this clinical trial is to test adding choline to ready-to-use therapeutic food (RUTF) in children with severe acute malnutrition (SAM) in Malawi. The main question it aims to answer is: \- Will the addition of a 500mg daily dose of choline to RUTF during treatment for SAM improve cognitive development among 6-59-month-old Malawian children compared with standard RUTF without added choline?

Alternative RUTFs for Treatment of Child Wasting

Acute malnutrition is the most life-threatening form of undernutrition. Moderate and severe acute malnutrition (MAM, SAM) are effectively treated with ready-to-use therapeutic foods (RUTFs) but there is a need to lower the cost of treatment and improve treatment regimens to reduce risk of relapse MAM/SAM episodes following recovery. The currently used standard formulation of RUTF contains peanuts and dairy, which pose problems due to their high cost, the need to import ingredients to the Global South (in the case of dairy), and risk of aflatoxin (in the case of peanuts). Before alternative formulations of RUTF can be recommended, however, there is the need for data on the efficacy of these formulations on recovery rates and to what extent recovery is sustainable. Sustainable recovery implies a lower rate of post-treatment relapse. The study objectives are as follows: (1) To assess the non-inferiority of soy-maize-sorghum (SMS-) RUTF and soy-based (S-) RUTF on treatment recovery to standard RUTF; (2) To assess the superiority of SMS-RUTF and S- RUTF on post-recovery relapse compared to standard RUTF; (3) To assess the costs of a treatment course of SMS-RUTF, S-RUTF, and standard RUTF; (4) To assess the effect of SMS-RUTF and S-RUTF on microbiome composition and intestinal inflammation The investigators will conduct a facility-based, individually randomized controlled trial with three arms allocated in a 1:1:1 allocation ratio in 30 health facilities (Centre de Santé et Promotion Sociale \[CSPS\]) in Burkina Faso. The investigators will randomize 1080 children with MAM and 1080 children with uncomplicated SAM 6-59 months of age to receive treatment with one of the following RUTFs: (1) standard of care, milk- and peanut-based RUTF (control group); (2) SMS-RUTF free of milk and peanuts and high in fiber (intervention 1); or (3) S-RUTF free of milk and peanuts (intervention 2). Children will be enrolled upon presentation to facilities for MAM or uncomplicated SAM treatment. Follow up visits will be weekly during treatment for SAM children and bi-weekly during treatment for MAM children, and monthly for 3 months following discharge from treatment. The primary study outcomes include, among others, anthropometric recovery at discharge (a non-inferiority analysis) and relapse to MAM or SAM within the 3 months following recovery (a superiority analysis). The investigators will employ an activity-based micro-costing approach to collect cost data on the direct and indirect medical costs, opportunity costs to caregivers, personnel, and overheads associated with outpatient MAM or SAM treatment. Fecal samples will be collected from children at a subset of facilities (5 facilities, \~60 children per treatment arm), at enrollment (initiation of treatment), discharge from treatment, and 3-months post-discharge.

Milk Fat Globule Membrane-Enhanced RUTF for Children With Severe Acute Malnutrition

The goal of this clinical trial is to test the use of milk fat globule membrane (MFGM) in ready-to-use therapeutic food (RUTF) in children with severe acute malnutrition in Sierra Leone. The main questions it aims to answer are: * Will the inclusion of MFGM in RUTF for 6-59-month-old Sierra Leonean children with severe acute malnutrition improve their neurodevelopment? * Will the inclusion of MFGM in RUTF for 6-59-month-old Sierra Leonean children with severe acute malnutrition reduce its worst consequences: death, hospitalization, and remaining severely malnourished despite treatment? Researchers will compare the MFGM-containing RUTF to standard RUTF, which contains skim milk powder. Participants will: * undergo measurement of length, weight, mid-upper arm circumference, and nutritional edema assessment every two weeks during severe malnutrition treatment * be treated with either MFGM-RUTF or standard RUTF at a dose of 2 sachets per day for up to 12 weeks * undergo neurodevelopmental testing using the Malawi Developmental Assessment Tool at the end of SAM treatment and 6 months later * a subset of participants will undergo blood spot collection and stool sample collection

Azithromycin as Adjunctive Treatment for Uncomplicated Severe Acute Malnutrition

Amoxicillin is recommended by the World Health Organization (WHO) as adjunctive therapy for the treatment of uncomplicated severe acute malnutrition (SAM). Because children with uncomplicated SAM may have asymptomatic infection due to immune suppression, presumptive treatment with a broad-spectrum antibiotic may be beneficial by clearing any existing infection and improving outcomes. Two randomized placebo-controlled randomized trials have evaluated amoxicillin for uncomplicated SAM and have found conflicting results. These results may indicate either that antibiotics are not helpful for the management of uncomplicated SAM, or that a better antibiotic is needed. Recently, the investigators demonstrated that biannual mass azithromycin distribution as a single oral dose reduces all-cause child mortality in sub-Saharan Africa. Children with uncomplicated SAM, who have an elevated risk of mortality relative to their well-nourished peers, may particularly benefit from presumptive azithromycin treatment. Our pilot data demonstrated feasibility in rapid enrollment of children with uncomplicated SAM in our study area, and showed no significant difference between azithromycin and amoxicillin, demonstrating equipoise for a full-scale trial. Here, the investigators propose an individually randomized trial in which children will be randomized to a) azithromycin, b) amoxicillin, or c) placebo, and evaluated for differences in weight gain, nutritional recovery, and the gut microbiome. The results of this study will strengthen the evidence base for policy related to the use of antibiotics as part of the management of uncomplicated SAM, including additional evidence of amoxicillin versus placebo as well as evaluation of an antibiotic class that has not been considered for uncomplicated SAM, which may lead to changes in guidelines for treatment.

Efficacy of Striatin in Malnourished Children

This is a double-blind randomized-controlled clinical trial to identify the effect of Striatin (snakehead fish extract) supplementation in increasing body weight, improving acute inflammatory markers and microbiota profiles in children with severe acute malnutrition (SAM) treating with standard nutritional therapy. The main questions to answer are: Does Striatin supplementation effective in increasing body weight and improving acute inflammatory markers in SAM children? What are the adverse events of Striatin supplementation in SAM children? Researchers will compare Striatin supplementation and placebo (a look-alike substance that contains no drug) to identify the increase of body weight, improvement of acute inflammatory markers and microbiota profiles.

Modified Dosage for Severe Acute Malnutrition

Protocols for the community-based management of acute malnutrition (CMAM) have not changed significantly for more than 20 years, with relatively complex treatment protocols and persistent supply chain challenges that have limited overall program coverage, leaving millions of malnourished children without care annually. The overarching goal of this research project is to simultaneously test two novel simplified approaches in CMAM with potential to improve program coverage. The simplified approach includes two parallel clinical trials for SAM and MAM treatment. Two fixed-dose regimes of RUTF will be tested against the current weight-based dosing of RUTF for children with SAM.

Family Mid-Upper Arm Circumference (MUAC) Follow-up After Recovery From Acute Malnutrition (MODAM-fMUAC)

Protocols for the community-based management of acute malnutrition (CMAM) have not changed significantly for more than 20 years, with relatively complex treatment protocols and persistent supply chain challenges that have limited overall program coverage, leaving millions of malnourished children without care annually. The overarching goal of this research project is to simultaneously test two novel simplified approaches in CMAM with potential to improve program coverage. The simplified approach includes two parallel clinical trials for SAM and MAM treatment. For the Family MUAC follow-up study, children who recover from these two parallel clinical trials will be enrolled in trial to test the effectiveness of MUAC screening at home by the child's caregivers as a self-referral strategy, compared to a scheduled health facility-led strategy and the standard of care of community-based follow-up visits.

Microbiota Directed Food for Children With Severe Acute Malnutrition

Severe acute malnutrition (SAM) refers to a condition characterized by a significant deficit in weight-for-length measurements in children aged 6 to 59 months. It is a crucial public health concern with detrimental effects on child growth, development, and overall well-being. Addressing SAM is crucial to prevent its progression to other childhood morbidity and mortality and to ensure healthy child development. To meet the nutritional requirement of SAM children, icddr,b have come up with a novel intervention named microbiota-directed food (MDF), a ready-to-use therapeutic food. The investigators propose this proof-of-concept trial to establish evidence on the effect of this novel intervention on ponderal growth, microbial and proteomic recovery among the children with SAM in comparison to the standard RUTF.
