NCT ID: NCT04097639 Recruiting - Anemia Clinical Trials

Inflammation, Iron Deficiency and Anaemia Study 1

Start date: May 7, 2019
Study type: Observational

Investigator have previously shown that hepcidin is up-regulated even by low levels of inflammation and, according to our prior stable isotope studies, is predicted to block iron absorption. In this follow-up observational study, investigator aim to elucidate the potential drivers of this low-grade inflammation and to recalibrate the relationship between hepcidin and iron absorption using a more direct measure of absorption than the stable isotope method which measures the net of absorption and utilization. Investigator will study 120 ostensibly well children (6-24m) living in the rural region of West Kiang. Investigator will: 1. Use detailed clinical screening for possible origins of the low grade inflammation. 2. Assess iron absorption and its relationship to iron and anaemia status, inflammation, EPO, erythroferrone and hepcidin.

NCT ID: NCT04095884 Recruiting - Clinical trials for Iron Deficiency, Anaemia in Children

An Observational Study Designed to Elucidate the Pathways by Which Inflammation Contributes to Anaemia in Sick Rural African Children From 6 Months to 36 Months

Start date: July 17, 2019
Study type: Observational

The Investigator have previously shown that hepcidin is up-regulated even by low levels of inflammation and, according to our prior stable isotope studies, is predicted to block iron absorption. In this follow-up observational study, the investigator aim to characterise the relationship between infections, acute inflammation, hepcidin and iron iron deficiency anaemia in rural African children. The Investigator will study 200 sick children (6-36 months of age) living in the rural region of West Kiang. The Investigator will: 1. Recruit 50 sick febrile children in each of 4 categories; Upper Respiratory tract infections, Lower respiratory tract infections (pneumonia), Urinary tract infections, gastroenteritis. 2. Assess iron absorption and its relationship to iron and anaemia status, inflammation, EPO, erythroferrone and hepcidin.

NCT ID: NCT04053907 Not yet recruiting - Malaria Clinical Trials

P. Falciparum Infection Dynamics and Transmission to Inform Elimination

Start date: August 15, 2019
Phase: N/A
Study type: Interventional

In the current study, three experimental approaches aiming at reducing malaria transmission will be tested. The study will cover two transmission season (2019 and 2020) and the interventions will vary by season. More specifically, in the 2019 transmission season (June-December) (Year 1), community case management of malaria (CCM) will be implemented in all eight villages as improved standard of care; in the 2020 transmission season (Year 2), the eight study villages will be divided into 4 study arms. CCM will continue in all villages; two villages will continue with CCM only (Arm 1, control); the three other pairs of villages will receive active fever screening and treatment (Arm 2); monthly mass screening and treatment (MSAT) (Arm 3); and mass drug administration (MDA) during the last 3 months of the dry season (April-June) (Arm 4). For MDA, the whole population (except for those not fulfilling the entry criteria) will be treated with a full course of dihydroartemisinin-piperaquine (DP) (320/40mg and 160/20mg piperaquine/ dihydroartemisinin per tablet) per manufacturer's guidelines (once daily for 3 days and according to body weight). The MDA treatment will be repeated 3 times at monthly intervals.

NCT ID: NCT03996967 Recruiting - Malaria Clinical Trials

Diagnostic and Prognostic Biomarkers for Childhood Bacterial Pneumonia

Start date: February 11, 2019
Study type: Observational

Clinical pneumonia is a leading cause of pediatric hospitalization. The etiology is generally bacterial or viral. Prompt and optimal treatment of pneumonia is critical to reduce mortality. However, adequate pneumonia management is hampered by: a) the lack of a diagnostic tool that can be used at point-of-care (POC) and promptly and accurately allow the diagnosis of bacterial disease and b) lack of a prognostic POC test to help triage children in need of intensive assistance. Antibiotic therapy is frequently overprescribed as a result of suspected bacterial infections resulting in development of antibiotic resistance. Conversely, in malaria-endemic areas, antibiotics may also be "underprescribed" and children with bacterial pneumonia sent home without antibiotic therapy, when the clinical pneumonia is mistakenly attributed to a co-existing malaria infection. The investigators previously identified combinations of protein with 96% sensitivity and 86% specificity for detecting bacterial disease in Mozambican children with clinical pneumonia. The investigators' prior work showed that it is possible to identify biosignatures for diagnosis and prognosis using few proteins. Recently, other authors also identified different accurate biosignatures (e.g., IP-10, TRAIL and CRP). In this study, the investigators propose to validate and improve upon previous biosignatures by testing prior combinations and seeking novel combinations of markers in 900 pediatric inpatients aged 2 months to 5 years with clinical pneumonia in The Gambia. The investigators will also use alternative case criteria and seek diagnostic and prognostic combination of markers. This study will be conducted in Basse, rural Gambia, in two hospitals associated with the Medical Research Council Unity The Gambia (MRCG). Approximately 900 pediatric patients with clinical pneumonia aged 2 months to 5 years of age will be enrolled. Patients will undergo standard of care test and will have blood proteins measured through Luminex®-based immunoassays. Results of this study may ultimately support future development of an accurate point-of-care test for bacterial disease to guide clinicians in choices of treatment and to assist in the prioritization of intensive care in resource-limited settings.

NCT ID: NCT03964012 Completed - Clinical trials for Meningococcal Meningitis

Study to Assess Immunegnicity & Safety of Pentavalent Meningococcal Vaccine (NmCV-5)

Start date: August 20, 2019
Phase: Phase 3
Study type: Interventional

This observer-blind, randomized, active controlled trial will be conducted among 2-29 year olds in two sites (Mali and The Gambia). The objectives of the study are to assess and compare the immunogenicity and safety of NmCV-5 with that of Menactra. A total of 1800 eligible participants (who or their parents/guardians have given written informed consent) will be randomised 2:1 (NmCV-5: Menactra) in each of the three age strata 18-29 years, 11-17 years & 2-10 years (400 NmCV-5 recipients & 200 Menactra recipients in each age strata). Each subject will receive a single dose of study vaccine and will be followed up for 6 months post vaccination during which solicited reactions (for seven days), unsolicited AEs (28 days) and SAEs (until the end of study i.e. 168 days after vaccination) will be collected. A blood sample will be collected at baseline (pre-vaccination) and at day 28 post-vaccination for immunogenicity assessment by a Serum Bactericidal Activity assay using rabbit complement (rSBA).

NCT ID: NCT03923725 Recruiting - Clinical trials for Plasmodium Falciparum Malaria (Uncomplicated)
