Study type: Interventional

The goal of this research is to study the associations of genetic variants of gout and kidney failure, which are very common in the Melanesian population in New Caledonia

NCT ID: NCT05328037 Recruiting - Diarrhea Clinical Trials

Study on the Association Between Vitamin C Deficiency and Diarrhea in Children

Start date: April 25, 2022
Study type: Observational

Diarrheal disease is the second leading cause of death in children under five, althought it is both preventable and treatable. The causative factors of diarrheal diseases vary a lot from region to region (bacteria, viruses, parasites). Diarrhea is one of the main causes of malnutrition in children under five years of age. Inversely, nutritional deficiency, particularly vitamin C deficiency, can be a risk factor for diarrhea. The main objective of this study is to assess the impact of vitamin C deficiency on diarrheal infection in children aged 2 to 5 years in countries with a high diarrheal rate. This pilot case-control study will be conducted in metropolitan France, Africa and South America. This question will be addressed by comparing vitamin C levels in children with diarrhea, regardless of the infectious agent, to levels in age- and sex-matched controls.

NCT ID: NCT05218304 Suspended - Diabetes Clinical Trials

Baromètre Santé Adulte 2021-2022

Start date: July 26, 2021
Phase: N/A
Study type: Interventional

In 2021-2022, Agence Sanitaire et Sociale Nouvelle Calédonie (ASSNC) is undertaking the "Baromètre Santé Adulte" for the third time. This study is carried out this year in collaboration with WHO and Institut Pasteur de Nouvelle Calédonie (IPNC). The main objective of this investigation is to describe the current levels of chronic disease risk factors in the adult population of New Caledonia aged from 18 to 64 years old. This study will also help to estimate prevalence of certain diseases (diabetes, hypercholesterolemia, renal failure), seroprevalence of arboviruses (dengue fever, Zika, chikungunya and Ross River) malaria as well as the seroprevalence of SARS-CoV-2. Repeated regularly, these surveys allow the ASS-NC to capitalize on population indicators, to compare them according to socio-demographic characteristics, to identify groups at risk, to provide changes in health behaviors and to strengthen analytical capacities in order to adapt the guidelines for public policies and prevention programs.

NCT ID: NCT05135585 Completed - Clinical trials for SARS-CoV-2 Acute Respiratory Disease

Evaluation of the Post-vaccination Immune Response to COVID-19 in the New Caledonian Population

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

The COVID-19 pandemic caused by SARS-CoV-2 since December 2019 has caused more than 210 million cases worldwide as of September 1, 2021. New Caledonia (NC) is an ultramarine French territory in the South Pacific so far relatively spared by this pandemic thanks to the establishment of a health lock. The vaccination campaign started locally on 20/01/2021 with the exclusive use of Pfizer's COMIRNATY mRNA vaccine. Vaccination is now offered to anyone over the age of 12. Vaccination against COVID-19 will be mandatory in New Caledonia as of October 31, 2021 for certain exposed populations and for the entire adult population as of December 31, 2021. Clinical trials of COVID-19 vaccines, including those of mRNA vaccines, have taken care to maintain ethnic diversity within their samples. Efficacy studies have not shown a significant difference in the efficacy of Pfizer COMIRNATY vaccine in white, black American, or Hispanic populations. The response of non-European non-Asian Oceanian populations to Pfizer COMIRNATY vaccination has not been specifically studied at this time. According to the 2019 census in New Caledonia, 41.2% of the population identified themselves as Kanak (Melanesian), 24% as European, 8.3% as Wallisian-Futunian (Polynesian), 11% as mestizo, and 8% as belonging to other communities including Tahitian (Polynesian), Indonesian, Ni-Vanuatu (Melanesian), and Vietnamese communities (8). Some recent data are in favor of a significant variability of susceptibility to pathogens in Oceanian populations, stemming from a genetic inheritance from Neanderthal man and his cousin Denisova man. In a context of vaccine hesitancy, it is therefore important to ensure that the immune response of the New Caledonian population (Melanesian, Polynesian, European or other communities) to vaccination against COVID-19 is similar to that of populations studied in large clinical trials.

NCT ID: NCT04882046 Recruiting - Leptospirosis Clinical Trials

Study of the Incidence of Jarisch-Herxheimer Reaction in Leptospirosis Patients in New Caledonia

Start date: July 23, 2021
Phase: N/A
Study type: Interventional

The objective of the study is to estimate the incidence of Jarisch-Herxheimer Reactions (JHR) during antibiotic treatment of human leptospirosis cases in New Caledonia. Participants are patients managed in one of the 5 centres participating in the study, in whom a clinical doctor suspected leptospirosis. The average number of leptospirosis cases in New Caledonia is 89 per year. Given the proportion of positive diagnostic tests (approximately 10%) 900 inclusions are planned for this study. Patients are included at the time of the consultation during which leptospirosis is suspected, before the initiation of their antibiotic therapy and independently of the clinical form they presented. Data (socio-demographic and health) and blood samples will be collected at 3 points in the study: at baseline, three hours and six hours after antibiotic treatment. This study will allow better management of patients with leptospirosis.

NCT ID: NCT04619823 Recruiting - Dengue Clinical Trials

Virological and Immunological Determinants of Arbovirus Infection in New Caledonia

Start date: February 15, 2021
Phase: N/A
Study type: Interventional

Arboviruses, diseases transmitted to humans by the bite of an insect vector, are a major public health problem, particularly in tropical and sub-tropical countries. In New Caledonia, dengue epidemics are recurrent and may be associated with the co-circulation of other arboviruses such as Zika or chikungunya. The virological determinants which condition the occurrence of these epidemics may be linked to an increased vectorial competence of the vector mosquito Aedes aegypti for a particular viral isolate. In fact, the Aedes aegypti mosquito is infected by making a blood meal on a person infected with an arbovirus. The virus infects its digestive tract, then spreads throughout the mosquito's body until it reaches its salivary glands. The virus is then present in the saliva and will be injected into the human host during a new blood meal. Some viral variants are best transmitted by Aedes aegypti. In general, the study of this vectorial competence is carried out by experiments in the laboratory during which an artificial blood meal composed of mammalian blood (human, rabbit, etc.) is mixed with a viral stock. Carrying out deported blood meals during which blood collected from patients infected with an arbovirus is used to gorge mosquitoes makes it possible to place oneself in experimental conditions as close as possible to the natural cycle of transmission of arboviruses. In the human host, cells of the myeloid lineage present in the peripheral blood constitute preferred targets of replication for arboviruses. At the same time, the peripheral blood cells of patients are activated in response to infection and secrete many soluble factors released into the blood of patients. The study of blood samples from patients infected with arboviruses is therefore of prime importance for understanding both the replicative mechanisms of arboviruses but also the immune response they induce.

NCT ID: NCT04328129 Completed - SARS-CoV Infection Clinical Trials

Household Transmission Investigation Study for COVID-19 in Tropical Regions

Start date: March 23, 2020
Phase: N/A
Study type: Interventional

This study is a interventional study that present minimal risks and constraints to evaluate the presence of novel coronavirus (SARS-CoV-2) or antibodies among individuals living in households where there is a confirmed coronavirus case in order to provide useful information on the proportion of symptomatic forms and the extent of the virus transmission in tropical regions such as French Guiana, Guadeloupe and New-Caledonia.

NCT ID: NCT03349190 Completed - Infertility, Female Clinical Trials

Impact of Esmya on Fertility to Infertile Women With Fibroids Managed With Assisted Reproduction Techniques

Start date: December 29, 2017
Study type: Observational

Fibroid is a frequent pathology of infertile women. Its deleterious effect on the infertility would be due to the mechanical way. The interest of the resection of intramural fibroids is discussed. It is necessary to measure the indication of a myomectomy, whatever the surgical procedure. On the one hand, it may cause important potential complications, and on the other hand, the surgery does not improve the parameters of the fertility. Thus, it is a major stake to avoid the surgical operation. A decrease of the size of these fibroids by medical treatment is then a good option. When the surgical treatment is necessary, a medical pre-surgical treatment is often proposed in order to decrease the symptomatology and to reduce the size of the fibroid to facilitate the surgery. Acetate Ulipristal (UPA) has been marketed in this indication. Following the Pearl I-II studies, the first indication in France was a pre-surgical treatment for 3 months at a dose of 5 mg per day. The Pearl III and IV studies evaluated the Esmya® administration as a long-term intermittent repeated treatment, giving to it a prominent position for the long-term management of symptomatic fibroids. Furthermore, cases of pregnancy before surgery are frequently described in women with fibroids treated by UPA for a pre-IVF surgery. 5 to 10 % of women who are managed for infertility have fibroids and only 2% to 3% have this unique cause of infertility. Then, some of patients followed in ART centers have been treated by UPA to reduce the fibroids size and/or to decrease the associate symptoms. The aim of this study is to evaluate in the different French ART centers, the impact on fertilization of UPA administration for infertile women with fibroids and to describe the modalities of its prescriptions and to collect information regarding safety tolerance profile of Esmya® in this patient population.

NCT ID: NCT02188862 Completed - Clinical trials for Rheumatic Heart Disease

Genetic Susceptibility to Rheumatic Heart Disease in the Pacific Region

Start date: September 2012
Phase: N/A
Study type: Observational

The purpose of this study is to investigate whether there are genetic differences between patients with rheumatic heart disease and members of the general population.

NCT ID: NCT00853762 Terminated - Clinical trials for Relapsing Multiple Sclerosis

Atacicept in Multiple Sclerosis Extension Study, Phase II

Start date: February 2009
Phase: Phase 2
Study type: Interventional

This study, 28851, is a long-term follow-up study of subjects enrolled in ATAMS study 28063, the aim of which is to monitor the safety and tolerability of atacicept administered for up to 5 years to subjects with relapsing multiple sclerosis (RMS). This extension study consists of two parts. Part A will be double blind and Part B will be open label. During Part A subjects initially randomized to atacicept will continue to receive the atacicept dose to which they have been randomized in study 28063 (ATAMS) once a week sub cutaneously (under the skin). Subjects randomized to placebo in ATAMS will receive atacicept at 150 mg once a week sub cutaneously during Part A. Once the results of ATAMS are available and the atacicept dose with the best benefit / risk ratio has been identified, all subjects will be switched to this dose and will continue the extension study open-label (Part B). Throughout the study, subjects and investigators will remain blinded with respect to intial and part A treatment allocation/dose.
