NCT01520597
Listeriosis is a foodborne infection responsible for severe disease. Three main forms are described: septicaemia, central nervous system infections and maternal-fetal infections. Available data on the disease, are mostly retrospective and do not provide an accurate picture of the clinical / biological / genetic risk factors for the disease, nor identify any element to determine which patients are at higher risk of death, severe neurological impairment or fetal loss. The primary purpose of the study is to identify clinical, biological and genetic risk factors for systemic listeriosis and the determinants of listeriosis-associated mortality in the setting of a large prospective nation-wide study.
NCT03357536
Listeriosis is a rare, severe foodborne infection, responsible for severe invasive infections. It occurs in the great majority of cases in elderly patients and / or patients with comorbidities, with a deficit of innate or cellular immunity. Pregnancy is also a risk factor. The Multicentric Observational NAtional Analysis of Listeriosis and Listeria (MONALISA) is an ongoing national case-control prospective study on listeriosis implemented since 2009 to study risk and prognosis factors for listeriosis. In this cohort, which enrolled 902 patients on 1 August 2014, 7% of patients with neurolisteriosis are under 40 years of age and have no identified risk factor. Genetic susceptibility is suspected in these patients. Genetic susceptibility could also explain the inconstant development of a neurolisteriosis or fetal infection, as well as the particular severity of some infections (death, foetal loss, neurological sequelae). The aim of the study is to identify genetic susceptibility to Listeriosis.
NCT02580812
The purpose of the study is to determine whether perinatal listeriosis is associated with long-term neurological consequences, and to evaluate the respective contribution of perinatal sepsis, of prematurity and of the known neurological tropism of the involved pathogen, Listeria monocytogenes.
