Active clinical trials for "Fever"

Evaluate the prognostic value of different methods (Osmometry / clinical-biological score) compared to the occurrence of capillary leak shock during dengue fever.

Fever is the most frequent symptom in patients seeking care globally. Several causative agents of febrile illness have been described with a high prevalence in South East Asia. They include malaria, dengue, Rickettsia, Leptospira and Burkholderia species. Since their introduction in the market, rapid diagnostic tests for malaria have driven patient management and care. Malaria negative cases are commonly treated with antibiotics without confirmation of bacteraemia. This can be explained by conventional laboratory diagnostic tests such as blood culture that usually require a skilled staff and appropriate facilities. Several Rapid Diagnostic tests (RDTs) are currently in the market but only limited data on their performance are available, rendering them unsuitable to replace laboratory conventional tests. In addition, RDTs have been developed for single disease diagnosis and remain costly for Low and Middle Income Countries (LMIC). Chembio, in collaboration with FIND (Foundation for Innovative New Diagnostics) and MORU (Mahidol Oxford Tropical Medicine Research Unit), has developed a multiplex lateral flow immunoassay (DPP® Fever Panel II Assay) that is able to detect serum immunoglobulin M (IgM) and specific microbial antigen of the most common agents of Acute Febrile Illness (AFI) in Asia. The assay comes with a reader that provides results interpretation to the operator. So far, DPP II assay performance has been estimated using a limited number of retrospective serum samples. More data are required to assess the performance of the assay using prospective serum samples. In addition, only limited data are available regarding the performance of the assay using blood samples. FIND will conduct a clinical trial to estimate the clinical performance of the assay in comparison to reference tests, using blood and serum samples and in intended settings of use.

Objective : To explore the diagnostic contribution of the 18F-FDG-PET/CT in a population of patients with classical fever of unknown origin (FUO), to precise its place in the diagnostic decision tree in a real-life setting and to identify factors associated with a diagnostic 18F-FDG-PET/CT. Methods: All adult patients (age≥18 years) with a diagnosis of classical FUO who underwent a 18F-FDG-PET/CT in the University Hospital of Montpellier (France) between April 2012 and December 2017 were included. True positive 18F-FDG-PET/CT which evidenced a specific disease causing FUO were considered to be contributive.

To develop a rapid, sensitive, and inexpensive diagnostic method, as well as more efficacious vaccine, for countries where typhoid fever remains a major public health burden.

Familial Mediterranean Fever (FMF) is an autosomal recessive inherited disease with a course of autoinflammation, which is characterized by the episodes of fever and serositis. Central sensitization (CS) is defined as increased response to normal or sub-threshold stimuli of central nervous system and its close relationship with many rheumatological diseases has been demonstrated in several studies. However, there are no data on the frequency of CS in FMF patients.

Following the decline of malaria in Sub-Saharan Africa, clinicians face febrile patients in whom an alternative diagnosis has to be made. This situation has led to an overuse of antibiotics by clinicians. It is crucial to increase knowledge on etiologies and risk factors of outpatient febrile illness in order to improve their management. This present proposal aims to investigate the etiologies of fever among adult patients attending an outpatient department in urban Tanzania. It also aims to assess the clinical significance of nasopharyngeal (NP) respiratory viruses and bacteria documentation in this setting. Third, it aims to compare the spectrum of infections in this population with that of children included in the same setting in a previous study. The last objective is to assess diabetes mellitus (DM) as a risk factor for infection and exposure to indoor air pollution (IAP) as a risk factor for acute respiratory infections (ARI) in adults in Tanzania. The investigators hypothesize that acute respiratory infections are the main cause of adult febrile illness in a urban low-income setting and that use of quantitative molecular assays on naso-oropharyngeal samples can improve the diagnosis of pneumonia. The investigators also think that the spectrum of infections is different between children and adults, mainly due to a high HIV prevalence in adults. The investigators also hypothesize that experiencing IAP and/ or DM is a risk factor for infections in adults.

The goal is to improve the evidence-based management of fever cases seen in outpatient clinics in malaria endemic countries, through a better understanding of the value of accurate malaria diagnosis, and through an improved understanding of the other causes of fever in children. The objective is to describe systematically (as much as possible) the etiologies of fever in children in an urban and in a rural environment of sub-Saharan Africa.

Dengue virus is an arbovirus transmitted by mosquitoes which causes significant morbidity and mortality among children in tropical regions, especially in resource limited countries. The objective of this protocol is to compare the sensitivity and specificity of clinical gestalt and two rapid antigen tests for dengue virus and to compare the gene expression of leukocytes in distinct dengue fever disease phenotypes module-based RNA microarray technology.

The purpose of this study is to collect data to support decisions made by BioFire regarding assay development, panel composition, and intended use for the final FilmArray FI reagent pouch. The study will utilize whole blood and/or plasma obtained from pediatric patients under 3 years of age that present with acute fever.

To study the changes in coagulation profile in patients undergoing cytoreductive surgery and Hyperthermic intraperitoneal chemotherapy. The objective of the study is to determine the utility of thromboelastography in comparison to standard coagulation tests in assessing the coagulopathy in patients undergoing CRS with HIPEC.
