NCT ID: NCT05312918 Not yet recruiting - HIV Infections Clinical Trials

Large Scale Transition to a Dolutegravir-based First-line ART in the South: Virological Response and Impact on HIV Drug Resistance in a Real Life Context (DoReaL Study)

Start date: May 2022
Study type: Observational

Main objective The main objective of the study is to assess the virological efficacy of a Dolutegravir-based first-line ART in use under real-life conditions in national programs in resource-limited settings in patients infected with HIV-1 and initially under a NNRTI-based first-line, and determine the impact of NRTI resistance on the success of the new strategy. Secondary objectives - Determine the level of virological suppression (HIV-1 RNA <200 copies/ml) at 6, 12 and 24 months after transition from an NNRTI first-line to a DTG first-line. - Determine the level of virological suppression at the WHO threshold (HIV-1 RNA <1000 copies/ml). - To determine the frequency of development of resistance and the profiles of mutations in patients with virological failure (HIV-1 RNA ≥200 copies/ml) and the potential impact on the 2nd line strategies combining DTG and currently recommended by the WHO. - To determine the impact of pre-transition resistance to NRTIs on the virological suppression under DTG first-line and on the development of resistance to integrase inhibitors. - Study pre-transition resistance acquired under DTG first-lines at the thresholds of 20% and 5% of the viral population, respectively using Sanger and Ultra-deep Sequencing (UDS) approaches. Identify program factors associated with virological failure and/or the development of drug resistance.

NCT ID: NCT05085340 Recruiting - Malaria Clinical Trials

MULTIple Doses of IPTi Proposal: a Lifesaving High Yield Intervention

Start date: February 14, 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.

NCT ID: NCT03803735 Recruiting - Pediatric Cancer Clinical Trials

Hospital Based Registry of Childhood Cancer in Pediatric Oncology Units in French Speaking Africa

Start date: January 1, 2016
Study type: Observational [Patient Registry]

The ultimate aim of this registry is to collect precise information concerning the children coming to oncology units working with the French African Oncology Group. This data will help to plan and provide correct pediatric oncology treatment and care for this population. Collecting the data will give much needed information on numbers, stage, treatment and outcome. The register will give data for local and national health authorities in planning pediatric cancer programs.

NCT ID: NCT02983487 Completed - Clinical trials for Bordetella Pertussis, Whooping Cough

Pertussis Immunization Programs in Low Income Countries

Start date: January 22, 2017
Study type: Observational

Due to waning of infectious as well as vaccine immunity and lack of vaccination boosters, a large number of adolescents and adults are no longer immunized against Bordetella pertussis, the agent of whooping cough and consequently may contract whooping cough. Furthermore, these populations represent a reservoir of the infectious agent from which the dissemination to non-immune infants is possible, causing severe illness, or even death, in this age group. Few studies have been carried out on whooping cough in developing countries (incidence, contaminator's age, etc.) and, specifically, none have assessed the duration of protection induced by the whole cell pertussis (wP) vaccine mainly presently used in these countries. However, data on the duration of vaccine induced protection are essential to determine i) the usefulness of vaccine boosters and ii) the target age group for these boosters. The aims of the present study are: - To evaluate the proportion of confirmed pertussis cases in infants presenting whooping cough syndrome (WP1a) - To evaluate the proportion of confirmed pertussis cases or healthy carriers among contact cases - To determine origin of the infant's contamination (WP1b) - To determine the duration of protection induced by the wP vaccines used in contact cases and the child population aged 3 to 15 yo (WP1b and WP2) - To bring new scientific evidences documenting the potential need for initiating boosters (WP1b and WP2) - To allow a comparison of the results with those obtained using the same methodology for the acellular pertussis vaccine and/or in other contexts. Potential implications for the use of pertussis vaccines in low and moderate income countries. - To increase local capabilities by the transfer of materials and expertise that will make the diagnosis of pertussis possible in the centres of reference and strengthen a pertussis monitoring network in the implicated countries. - To improve children's health through a better match of the vaccination schedule according to the reality of the situation.
