Effectiveness of Seasonal Malaria Chemoprevention in Nampula Province, Mozambique: Type Two Hybrid Implementation Study

Start date: January 10, 2022
Phase: Phase 4
Study type: Interventional

We describe a Type II hybrid effectiveness-implementation study design which evaluates the effects of a clinical intervention on relevant outcomes whilst collecting information on implementation. It is designed to determine feasibility and effectiveness of an innovative intervention, as well as the protective efficacy of the drugs used. The study consists of three components: 1) Conducting a cluster randomized controlled trial (cRCT) through household surveys establishing confirmed malaria cases in children; 2) Conducting a prospective cohort study to determine the chemoprevention efficacy of sulfadoxine-pyrimethamine and amodiaquine (SPAQ) and whether drug concentrations or parasite resistance influence the duration of protection; and 3) Conducting a resistance markers study in children 3-59 months to measure changes in resistance marker prevalence over time.

NCT ID: NCT05103033 Not yet recruiting - Clinical trials for Mental Health Disorder

Systems Analysis and Improvement Approach to Optimize the Task-shared Mental Health Treatment Cascade (SAIA-MH)

Start date: April 1, 2022
Phase: N/A
Study type: Interventional

The purpose of this study is to test the effectiveness of a multicomponent implementation strategy entitled the Systems Analysis and Improvement Approach for mental health (SAIA-M) using a cluster randomized trial at the health facility level. SAIA-MH focuses on improving the mental health treatment cascade in primary outpatient mental healthcare. The mental health treatment cascade is a model that outlines the sequential, linked treatment steps that people with mental illness must navigate, from initial diagnosis to symptom/function improvement. This study will also assess the potential mechanisms by which the SAIA-MH implementation strategy works, or does not work, along with the cost and effectiveness of scaling-up SAIA-MH in Mozambique.

MULTIple Doses of IPTi Proposal: a Lifesaving High Yield Intervention

Start date: January 2022
Study type: Observational

MULTIPLY is a multi-country 40-month implementation research project, which aims to catalyse country uptake of Intermittent Preventive Treatment of malaria in infants (IPTi) and inform future policy and guidelines in moderate-to-high malaria transmission settings. The project has been conceived following a before-after evaluation design of the impact of the intervention. The primary outcome measure will be the coverage of three or more doses of IPTi in children under 2 years of age (U2) attending the Expanded Programme on Immunisation (EPI) in project areas. IPTi will be delivered at health facilities and mobile-outreach EPI clinics to all children living in project districts. The number of IPTi doses a child will receive will be based on the EPI schedule of the country, with a maximum of 6 doses in the first 2 years of life. The prophylactic effect of IPTi provides protection for up to 6 weeks in infants. Therefore, in the current WHO-recommended IPTi scheme, infants are exposed to the infection for about 4 months during a critical period of high susceptibility to harmful effects of the infection. Exploiting additional opportunities to administer IPTi to children in their first years of life could be of great public health interest. In settings where vitamin A deficiency is a public health problem WHO recommends vitamin A supplementation, habitually done through the EPI scheme starting at 6 months of age, at 6 months intervals; thus, the addition of IPTi at 6, 12, 15-18 months of age to vitamin A administration would improve malaria prevention during a critical time in the first year of life and expand it into the second. Moreover, the integration of these two interventions might help increase the coverage of vitamin A supplementation, which ranges between 53%-57% in sub-Saharan Africa and importantly will help reduce the prevalence of anaemia in young children by combining the effect of malaria prevention and of vitamin A on increasing haemoglobin levels. Additionally, in recent years the inclusion of a booster dose of measles immunisation in the EPI, between 15-18 months of age, also offers the opportunity of further expanding malaria protection in the second year of life using IPTi. This is particularly relevant given that severe malaria cases are more prevalent between 1 and 3 years of age in high and moderate transmission areas.

Evaluating a New Stool Based qPCR for Diagnosis of Tuberculosis in Children and People Living With HIV

Start date: October 1, 2021
Study type: Observational

Stool4TB aims to evaluate an innovative stool-based qPCR diagnostic platform (with the capacity to become a POC diagnostic tool) in the high TB and HIV burden settings of Mozambique, Eswatini and Uganda, under the hypothesis that it will narrow the extremely large TB case detection gap by improving TB confirmation rates in children and people living with HIV (PLHIV).

NCT ID: NCT05022407 Recruiting - Covid19 Clinical Trials

Impact of COVID-19 Epidemic on Clinical Outcomes and Service Delivery Among People Living With HIV and Health Care Workers in Mozambique

Start date: July 15, 2021
Study type: Observational

While COVID-19 (coronavirus disease 2019) is an important emergent issue for all in the country, there is a significant number of people in the population who are especially vulnerable to the potential impact that the novel coronavirus epidemic may have on their health. The overall purpose of the study is to investigate: (1) the dynamics of COVID-19 infection among people living with HIV and health care workers providing HIV services; (2) the provision of HIV and HIV/TB care and treatment services at health facilities, within the scope of COVID-19 or in the context of COVID-19 and; (3) the perceptions of COVID-19 and access to care among people living with HIV and health care workers providing HIV services.

NCT ID: NCT04930367 Recruiting - HIV Clinical Trials

CombinADO: Evaluation of an Intervention Aimed at Improving HIV Outcomes Among Adolescents and Young Adults Living With HIV in Mozambique

Start date: September 13, 2021
Phase: N/A
Study type: Interventional

This is a cluster-randomized trial designed to compare the effectiveness of the CombinADO strategy versus optimized standard of care (SOC) on viral suppression, antiretroviral therapy (ART) adherence and retention in HIV care among adolescents living with HIV (ALHIV) ages 10 to 24 years attending participating health facilities. Clinics are the units of intervention allocation and randomization. The control condition will be implemented at all facilities (n=12) participating in the trial. The enhanced intervention condition will be superadded to this at a randomly selected half (n=6) of facilities. The goal of this study is to learn whether an enhanced, tailored intervention helps AYAHIV do better with their HIV care (take their medications, stay in care) than the usual care that they receive.

NCT ID: NCT04825327 Recruiting - Tuberculosis Clinical Trials

Predicting the Future: Incipient Tuberculosis

Start date: April 21, 2021
Study type: Observational [Patient Registry]

The investigators will study, prospectively, if contacts (household or close contacts) of tuberculosis (TB) patients with high C-reactive protein (CRP), low hemoglobin (Hb) levels, and a positive Xpert Host Response (HR) cartridge result develop active TB within 12 months. They will also investigate if there is a correlation between progressing to active TB within 12 months and having high levels of the iron homeostasis markers (Hepcidin, Ferritin and Transferrin). Identified index cases who agree to participate will refer their household or close contacts to also join the study. These contacts will be tested for TB and only contacts who are negative will be enrolled and followed-up at 6 months and 12 months. Blood samples will be collected at baseline and 6 months for testing. During the study period, TB testing will be done on contacts who meet symptoms criteria. At 12 months, all contacts will undergo a chest x-ray to assist in the diagnosis of TB. PreFIT will target people aged 12 to 60 years of age and both HIV negative and positive. 1515 trial participants will be recruited at Stellenbosch University in South Africa, 1515 at Fundaçao Manhiça in Mozambique and 1010 at Makerere University in Uganda, respectively.

NCT ID: NCT04781257 Recruiting - Tuberculosis Clinical Trials

Early Risk Assessment in Household Contacts (≥10 Years) of TB Patients by New Diagnostic Tests in 3 African Countries

Start date: March 2021
Study type: Observational

The ERASE - TB study will be conducted in order to fill a critical unmet need for tuberculosis control. Persons who are in contact with an infectious TB case may become infected themselves. Among those who are infected, most will stay healthy but some will develop TB themselves. These people would benefit from preventive treatment, which would also stop TB from being spread to other persons. The problem currently is that it is impossible to determine with certainty who would require preventive treatment, and who will remain healthy. Out of 100 persons exposed to an infectious TB patient, only 2 will go on to have TB according to a study in Vietnam, but there are no good tests available to identify those with a risk for TB disease. Treating 100 persons to prevent 2 cases of TB is not effective, so preventive treatment is not used in adults and adolescents in Tanzania, Mozambique and Zimbabwe, where this study will be conducted, but also in many other settings. The ERASE - TB project will evaluate a number of newly developed diagnostic tests, to see which of those will be able to predict TB in persons at risk, and therefore steer preventive treatment well. For this, the investigators will invite 2,100 household contacts (HHC) of infectious TB patients, who are at least 10 years old, into the study. Everyone will be examined initially, and again in regular intervals, for 1.5 to 2 years; and whenever the participants will present with symptoms that could indicate that they develop TB. At every visit, the investigators will perform an X-ray and take some blood and urine samples to perform new candidate tests. At the first/baseline visit, all household contacts without TB will undergo a spirometry to evaluate their pulmonary function. If someone is unwell, the investigators will also examine sputum for the presence of TB bacilli. In the end, the investigators will then be able to say who of the persons in the study developed TB, and who remained healthy. From all samples taken at different timepoints, the investigators will then determine which test found TB early, and clearly distinguished between persons developing TB, and persons who would remain healthy .

NCT ID: NCT04724161 Recruiting - Malaria Clinical Trials

Antenatal Care as a Platform for Malaria Surveillance: Utilizing Community Prevalence Measures From the New Nets Project to Validate ANC Surveillance of Malaria in Mozambique

Start date: December 9, 2020
Study type: Observational

This study outlines a plan for conducting a routine assessment of malaria infection prevalence and intervention coverage using antenatal care (ANC) attendees. This will be a non-randomized assessment of the potential to use pregnant women attending their first ANC visit as a pragmatic sentinel population to monitor prevalence of malaria and the coverage of malaria control interventions. The use of a questionnaire, to include standard malaria rapid diagnostic testing, will be piloted with consenting women attending their first ANC visit at 21 individual health facilities across three of the New Net Project pilot study districts in western Mozambique: seven facilities each from Changara, Chemba, and Guro Districts. The results of the ANC questionnaires will be analyzed to see how well they correlate to similar malaria prevalence and intervention coverage estimates obtained during the contemporary community-based cross-sectional surveys administered during New Net Project pilot evaluation activities. As part of the New Nets Project, Mozambique is deploying next-generation ITNs through mass campaigns in pre-determined provinces. The present study aims to leverage planned New Nets Project cross-sectional surveys and strengthened routine case surveillance data in three of the study districts (Changara, Guro, and Chemba) to assess (1) whether the malaria infection prevalence data collected during ANC surveillance correlates with the cross-sectional survey estimates of community infection prevalence in children 6 to 59 months and (2) if intervention coverage data (particularly ITN ownership and use) collected from ANC surveillance are valid and representative of the population as a whole. These additional data could catalyze a new model of surveillance for malaria, and greatly simplify evaluation of the impact of new interventions, as ANC surveillance could potentially replace or supplement cross-sectional household surveys and provide more granular and timely data. All pregnant women attending first ANC visit at seven health facilities in each study district will be eligible for enrollment. Potential participants will be approached during their visit by a health facility worker. During group counselling sessions at initial intake, women will be informed of this pilot surveillance activity, and written informed consent will be obtained from each woman individually prior to routine ANC testing. All consenting women attending ANC first visit at a participating health facility will be tested for malaria using an RDT and asked to complete a study questionnaire which will include questions about the participant's net use, and care seeking behavior. It is expected to take 15 minutes to complete. Women who test positive for malaria will be given treatment according to national guidelines. There is no additional benefit to individual participants.
