NCT ID: NCT06450379 Completed - Vaccine Clinical Trials

Impact of Vaccines on Antimicrobial Microbial Resistance

IVAR
Start date: March 15, 2021
Phase:
Study type: Observational [Patient Registry]

Vaccination is a potentially critical component of efforts to arrest development and dissemination of antimicrobial resistance (AMR), though little is known about vaccination impact within low-income and middle-income countries. This study will evaluate the impact of vaccination on reducing carriage prevalence of resistant Streptococcus pneumoniae and extended spectrum beta-lactamase-producing Escherichia coli and Klebsiella species. We will leverage two large ongoing cluster-randomised vaccine evaluations in Malawi assessing; first, adding a booster dose to the 13-valent pneumococcal conjugate vaccine (PCV13) schedule, and second, introduction of the RTS,S/AS01 malaria vaccine. Six cross-sectional surveys will be implemented within primary healthcare centres (n=3000 users of outpatient facilities per survey) and their local communities (n=700 healthy children per survey): three surveys in Blantyre district (PCV13 component) and three surveys in Mangochi district (RTS,S/AS01 component). We will evaluate antibiotic prescription practices and AMR carriage in children ≤3 years. For the PCV13 component, surveys will be conducted 9, 18 and 33 months following a 3+0 to 2+1 schedule change. For the RTS,S/AS01 component, surveys will be conducted 32, 44 and 56 months post-RTS,S/AS01 introduction. Six health centres in each study component will be randomly selected for study inclusion. Between intervention arms, the primary outcome will be the difference in penicillin non-susceptibility prevalence among S. pneumoniae nasopharyngeal carriage isolates in healthy children. The study is powered to detect an absolute change of 13 percentage points (ie, 35% vs 22% penicillin non-susceptibility). This study has been approved by the Kamuzu University of Health Sciences (Ref: P01-21-3249), University College London (Ref: 18331/002) and University of Liverpool (Ref: 9908) Research Ethics Committees. Parental/caregiver verbal or written informed consent will be obtained prior to inclusion or recruitment in the health centre-based and community-based activities, respectively. Results will be disseminated via the Malawi Ministry of Health, WHO, peer-reviewed publications and conference presentations.

Arm 2: Intermittent preventive treatment with sulfadoxine-pyrimethamine (SP) plus chloroquine (CQ) (IPT-SPCQ). Arm 3: Control - students will receive standard of care (no preventive treatment). Outcomes include P. falciparum infection and parasite density, anemia, cognitive function and educational testing, as well as infection prevalence in young children sleeping student's households to assess the impact on transmission.

NCT ID: NCT05783310 Completed - Pediatric Cancer Clinical Trials

Psychoeducation Intervention for Caregivers of Children With Cancer

Start date: May 22, 2023
Phase: N/A
Study type: Interventional

This randomized controlled trial aims to evaluate the effectiveness of the psychoeducation intervention on anxiety, depressive symptoms, coping, and HRQoL in caregivers of children with cancer. The study is a two-arm parallel-group single-blind, randomized controlled trial that will be conducted in two hospitals in Malawi.

NCT ID: NCT05746819 Completed - Malaria Clinical Trials

An MRI Ancillary Study of a Malaria Fever Investigation

MRIA
Start date: January 2, 2021
Phase:
Study type: Observational

This study will seek consent from parents of children enrolled in the Malaria FEVER study to obtain neuroimaging and 12-month neuropsychiatric outcomes data and kidney function on their child. The imaging and evaluations for this observational study will occur after the child has recovered from the acute malaria infection and has otherwise completed the RCT intervention and safety evaluations.

NCT ID: NCT05746065 Completed - HIV Infections Clinical Trials

A Cohort for Evaluation of Open-label PrEP Use and PreP Preferences Among African Women

INSIGHT
Start date: August 1, 2022
Phase:
Study type: Observational

INSIGHT is a Prospective, Observational, open-label cohort study on women in Sub-Saharan Africa on PrEP screening, informed choice, and compliance. There are no specific intervention arms or comparative treatment plans. We will follow and observe participants taking PrEP, not taking PrEP, as well as those who begin or end PrEP during the course of the observational period.

NCT ID: NCT05737472 Completed - Clinical trials for Severe Acute Malnutrition

High-protein Quantity and Quality RUTF in Improving Linear Growth Among Children With Severe Wasting

Protein+
Start date: November 14, 2022
Phase: N/A
Study type: Interventional

This is a proof-of-concept trial that aims to compare the efficacy of an 8-week treatment with higher-protein-Ready-to-Use Therapeutic Foods (RUTF) with standard RUTF in improving levels of markers of growths, height, nutritional recovery, and lean mass deposition among children with severe wasting. The study will also assess the safety and acceptability of the high-protein RUTF in comparison to the standard RUTF. The study will be conducted at four outpatient therapeutic programs in the Blantyre district of Malawi.

NCT ID: NCT05409274 Completed - Covid19 Clinical Trials

Understanding COVID-19 Infections in Pregnant Women and Their Babies in 5 African Nations (periCOVID Africa)

Start date: November 1, 2020
Phase:
Study type: Observational

Develop coronavirus disease 2019 (COVID-19) surveillance in pregnancy in The Gambia, Kenya, Malawi, Mozambique and Uganda Estimate the seroepidemiology of COVID-19 infection among pregnant women in these countries Define the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in pregnant women and their babies and determine the presence of antibodies in cord blood Work with communities to develop understanding of infection prevention and control techniques to reduce the spread of COVID-19 amongst the pregnant population

NCT ID: NCT05343390 Completed - Clinical trials for Human Immunodeficiency Virus

Package of Resources for Assisted Contact Tracing: Implementation, Costs, and Effectiveness

PRACTICE
Start date: November 1, 2021
Phase: N/A
Study type: Interventional

Having health workers assist HIV-infected persons with the recruitment and testing of their sexual contacts and biological children is an effective and efficient way of identifying additional HIV-infected persons in need of HIV treatment and HIV-uninfected persons in need of HIV prevention. However, in Malawi, a country with a generalized HIV epidemic, health workers lack the counseling and coordination skills to routinely assist their HIV-infected clients with these services. This study will determine how to help health workers to effectively and efficiently provide these services to their patients through a set of digital capacity-building tools.

NCT ID: NCT05323396 Completed - HIV Coinfection Clinical Trials

HIV And Parasitic Infection (HAPI) Study

HAPI
Start date: May 2, 2022
Phase: N/A
Study type: Interventional

The overall goal of this study is to determine if periodic de-worming of persons living with HIV in intestinal parasite-endemic regions will lead to decreased morbidity and mortality associated with HIV by reducing immune activation and intestinal damage associated with these diseases. The hypothesis for this project is that intestinal parasitic infections contribute to a modifiable pro-inflammatory state in persons living with HIV (PLWH). Aim 1: Determine the prevalence of intestinal parasitic infections in PLWH receiving care at an HIV-treatment center in Lilongwe, Malawi using a highly sensitive multi-parallel stool PCR test. Hypothesis: highly sensitive stool PCR testing will demonstrate that disease burden of parasitic infection in PLWH in Malawi is higher than historically reported based on stool microscopy. Aim 2: Determine the impact of parasitic infection on intestinal damage and immune activation by measuring sCD14, sCD163, and intestinal fatty acid binding protein (I-FABP) in PLWH. Hypothesis: plasma biomarkers reflecting intestinal damage and immune activation are elevated in those with HIV and parasitic co-infection compared with parasite-negative participants with HIV. Aim 3: Determine the impact of eradication of parasitic infection on intestinal damage and immune activation by measuring sCD14, sCD163, and intestinal fatty acid binding protein (I-FABP) in PLWH before and after treatment of parasitic co-infection. Hypothesis: plasma biomarkers reflecting intestinal damage and immune activation are elevated in those with HIV and parasitic co-infection, and these biomarkers decrease with anti-parasitic treatment.
