Active clinical trials for "Virus Diseases"

This study will evaluate subjects with fever and/or rash to determine the percentage of those infected by the Zika, Chikungunya, or Dengue virus. The study will also compare the clinical signs, symptoms, and lab abnormalities related to each virus, to better specify each virus's characteristics.

Hepatitis E virus (HEV) is an emerging disease. The genotype 1 and 2 are predominant in Asia and Africa, and are responsible for recurrent epidemics. Genotype 3 is the main genotype found in Europe and North America and is responsible for sporadic infections except for travel associated diseases. HEV had a principally asymptomatic form. However, it was recently demonstrated that it could lead to a chronic form, especially in immunosuppressed patients. Moreover, in liver transplanted patients the infection could mimic a rejection and lead to the loss of the transplant. In other immunosuppressed patients, chronic hepatitis lead to cirrhosis and its well-known complications (ascitis, digestive hemorrhage, liver failure...). There is a lack of information about the prevalence of this disease. In Canada the incidence of HEV infection was high (15-86% for liver transplanted children with liver tests disturbed). In Germany the prevalence was lower: 3,2% in liver & kidney transplanted children whereas 7,4% in control. It was shown in a retrospective study that in liver (and liver+kidney) transplanted children the prevalence in Lyon was around 8,3%. This study will determined in a prospective approach the HEV prevalence in kidney, lung, heart and bone marrow transplanted children in Lyon.

The overall objective of this multisite, multicountry Zika in Infants and Pregnancy (ZIP) study is to assess the strength of the association between Zika virus infection (ZIKV) during pregnancy and adverse maternal/fetal outcomes and the risk of vertical transmission. The study will prospectively enroll a cohort of pregnant women up to 17 weeks and 6 days gestation and subjects at any gestational age with acute Zika infection, confirmed by serology or PCR (polymerase chain reaction) test. The study will follow these women through their pregnancy to identify for clinical evidence of acute ZIKV, while controlling for potential confounders. Outcomes in the women, the developing fetus, and infants will be assessed. All protocol-specified data will be recorded and entered in a central data management system for the purposes of analysis of composite data from the study.

This study of neurotropic viral infection and Tuberculous CNS infection is the comprehensive investigation of CSF PCR arrays (Hybrydiaztion technique,Sybergreen and Taqman real time PCR arrays of CSF ) in suspected cases of viral CNS infection, Tuberculous CNS infection in both AIDS and non AIDS patients. Patients with clinical viral encephalitis and all meningoencephalitis including all patients with HIV/AIDS CSF and non AIDS will be banked and test for RNA and DNA viral sequence by Real time PCR arrays and IS6110 gene of Mycobacterium tuberculosis. Clinical data and final diagnosis will be used to analyze the result of this PCR arrays technique compared to clinical gold standard criteria.

It is proposed that patients with skin disease due to presumed immunologic, genetic or viral-induced abnormalities, patients with neurological degenerations, and normal controls be evaluated with various in vitro studies of immunologic, genetic, and virologic function. This is to include studies of peripheral blood (cells and serum) as well as studies of skin obtained with a biopsy instrument. In addition, studies of gastrointestinal function will be performed where appropriate.

Egypt has the highest prevalence of hepatitis C virus (HCV) in the world. In 2015, the prevalence of HCV RNA was found to be 7.0%.(1) The prevalence of HCV was studied in Rheumatoid arthritis in few studies(2,3), but to our knowledge, no previous work studied it in other rheumatologic diseases.

This is an epidemiological, retrospective and observational study, by reviewing clinical histories, of children hospitalized for influenza virus infection, their comorbidities and the treatments that have been performed

Introduction: It is estimated that more than one million Brazilians were infected by zika virus in the last two years. Brazilian researchers first noted the virus's potential association with microcephaly. Objective: This study aimed to describe the motor performance of children aged between 6-18 months with the diagnoses of congenital Zika syndrome. Method: This is a cross-sectional, prospective and descriptive study. The study population consisted of 31 children. Participants were evaluated using Alberta Infant Motor Scale (AIMS) and Gross Motor Function Measure (GMFM).

Acute upper respiratory tract infection(AURI) is common in children, and viral infection is the main cause. However, several children with viral infection are easy to suffer from secondary bacterial infection, and the mechanism is unclear.

Hepatitis E Virus (HEV) infections are emerging in the Western world with a predominance of HEV genotype (gt) 3. Except for age older than 50 years, male gender, chronic liver disease and immunosuppressed status, no correlators with clinical outcomes have been identified so far. With this study, we want to examine viral factors associated with the morbidity and mortality of HEV infections in Belgium as well as find correlators with clinical outcomes.
