Active clinical trials for "Fever"

The purpose of this study is to assess the dynamics of inflammatory parameters in presence or absence of infectious complications after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy.

The proposed study is a collaboration between Microbiology, SU/Sahlgrenska and the Infectious Diseases clinic at SU/Östra as well as several Infectious Diseases clinics throughout Sweden aiming at improving microbiological diagnostic assays regarding the early identification of tick-borne microorganisms (including as of yet unidentified pathogens) capable of causing human disease using modern diagnostic tools. At the initial study visit (day 0) plasma, serum, urine, saliva, and PBMCs (and tick, if available) will be collected from patients developing fever within two weeks after a tick bite. Additional follow-up samples will be obtained after 9 and 30 days as well as after 6 months. The initial samples will be analyzed using (a) directed multiplex PCR analysis for Tick-Borne Encephalitis (TBE), Borrelia, Anaplasma, Neoerlichia, Rickettsia, Coxiella, Tularemia, and Babesiosis in plasma, whole blood and urine, (b) conventional IgM and IgG serology for TBE, (c) "Next Generation Sequencing" (NGS) for the detection of bacterial 16s rRNA as well as unknown viruses, (d) potential biomarkers, and (e) host genetic factors. Among patients where initial sampling indicates the presence of a potential pathogen or in patients developing neurological symptoms, a lumbar puncture will be performed and CSF will be further analyzed. Samples will also be evaluated regarding potential microbiological factors predisposing for severity of infection. The primary objective of the study is to improve diagnostic tools in the initial early phase of infections caused by tick-borne pathogens, especially TBE prior to the affliction of the central nervous system, and to attempt to identify which factors impact the course of infection as it is believed that approximately 75% of infected individuals resolve their infection in this first phase whereas others develop meningoencephalitis with significant subsequent neurological sequelae. Secondary objectives of the study include investigating for the presence of and treating other tick-borne pathogens, setting the stage for coming clinical trials evaluating novel anti-viral therapies for TBE.

Study design: The Spanish registry of RYR1 and CACNA1S polymorphisms (RYCA) is an anonymous descriptive observational multicentre study that aims to identify and catalogue the variants or polymorphisms in the RYR1 and CACNA1S genes in the Spanish population. Secondarily, its correlation with the binding mutations described in both genes at European level by the EMHG will be evaluated to assess the incidence of malignant hyperthermia in Spain. The RYCA registry complies with the highest standards of European and international homologation, both with regard to computer security and the protection of personal data (Data Protection Law 15/1999). Hypothesis: Performing a Spanish registry of RYR1 and CACNA1S polymorphisms will contribute to describe the variants present in our environment and determine their relationship with MH susceptibility. Objectives: Describe the national polymorphisms of the RYR1 and CACNA1S genes To evaluate the incidence of genetic MH susceptibility according to the recommendations of the EMHG. The presence of polymorphisms in a population that has not been studied before may have a difficult correlation with the mutations described in the EMHG webpage. Eligibility Criteria: The sample contained in the registry will originate from the genetic data of patients unrelated to HM who have been sequenced the RYR1 and CACNA1S gene by another pathology. The data related to the genetic analysis will be provided without identifying data of the patient or the clinical history. There will be no possibility of identification of the patient by the team responsible for the RYCA registry, so the request for informed consent is not viable. There will be no selection of participants or patient follow-up. Methodology: A preliminary pilot study will be conducted in an unselected anonymous cohort of the sequenced exome database of the RYR1 and CACNA1S gene at the La Fe Health Research Institute (IISlaFe). The population contained in this database is random and unrelated to HM and the patients are anonymous, so we do not have access to personal data or medical history. If the analysis is feasible, a request for collaboration will be transferred to the Genetics Services / Research Units with experience in the exome sequencing of the RYR1 and CACNA1S genes. Anonymous readings will be requested to carry out the registration and description of the variants existing in the Spanish population and their relationship with the variants described by the EMHG. Variables: The registry will include the chromosomal coordinates, number of total patients included, number of patients whose variant is in heterozygosis, number of patients whose variant is in homozygosis and allelic frequency. Thus, for each of the genes of interest, and making use of their respective chromosomal coordinates, information regarding the variants that these might include will be extracted. Sample size. Sample size calculation is not considered since it is a descriptive record.

The study will collect the blood samples from 350 healthy persons and 350 persons infected with dengue fever.

Febrile seizures are one of the most common clinical diseases in pediatric neurology. It occurs between 6 months and 6 years of age and occurs in ~2-5% of children. According to the age, frequency, duration, and type of seizures FS is divided into simple febrile seizures and complex febrile seizures Differentiation between febrile seizures and non-ictal events associated with fever such as shivering or dizziness is challenging. Therefore, precise diagnosis of FS after paroxysmal episodes associated with fever is often hindered by the lack of an objective biomarker With the widespread application of technologies, such as molecular biology, in medicine, some biomarkers for predicting or diagnosing FS have attracted attention. Imuekemhe et al in 1989 and 1996 found that lactic acid in the serum and cerebrospinal fluid of children with FS was significantly increased . Arginin-vasopressin hormone AVP released by the pituitary gland, has been shown to be involved in the thermoregulatory response to fever and convulsions Although AVP is unstable in the peripheral blood and, therefore, unsuited for diagnostic use the C-terminal portion of the AVP precursor copeptin has been recognized as a robust marker of AVP secretion . Wellman et al. found that the serum copeptin and Von Willebrand factor of children with FS were significantly higher than those of the control group .

Febrile syndromes after tick bites can be caused by different microorganisms: bacteria (B. miyamotoi, A. phagocytophilum, R. helvetica…), parasites (Babesia spp) and viruses (TBE virus). The clinical picture is not specific but complications may appear depending on the microorganism identified (thrombosis with N. mikurensis, meningoencephalitis with B. miyamotoi and the TBE virus). Thus, in order to provide appropriate treatment and monitoring, the infection should be documented.

Study goal - to describe pediatric patients with febrile disease that administered to the emergency department (ED) of hillel-yaffe hospital, according to arrival diagnosis, ED diagnosis, given therapy, and therapy concordance with the guidelines and final diagnosis. This research will describe cases that arrived to the hospital with acute febrile disease (up to seven days of fever), the antibiotic treatment given in the community according to the anamnesis and the community physician letter, therapy concordance with the guidelines, the ED diagnosis and changes in therapy, and final diagnosis according to extended microbiological examinations and panel of infectious disease specialists.

Objectives： To assess the percentage of febrile neutropenia and suspected fungal-related febrile episodes in patients receiving chemotherapy To explore the percentage/distribution of infectious origins of febrile neutropenia To explore the percentage/distribution of infectious pathogens of febrile neutropenia To explore clinical outcomes of different infectious origins/pathogens in febrile neutropenia episodes To have a clear view of therapeutic actions in the management of hematological patients with febrile neutropenia and suspected fungal-related febrile episodes

Intrapartum fever associated with epidural anesthesia is caused by non infectious causes therefore without histological findings

Familial Mediterranean fever (FMF) is an inherited disorder of unknown etiology, characterized by recurrent episodes of fever, peritonitis and/or pleuritis. Fever is the cardinal manifestation of FMF and is present in most attacks accompanied by abdominal pain. Another clinical manifestation in patients with FMF is exertional muscle pain, usually in the thigh, which appears even after minor exercise or physical activity in young patients with generally good health (other than FMF) and in good physical condition. Some patients also complain of ankle edema after relatively minor physical activity, which subsides after a night rest. Although these manifestations are quite common in FMF patients and form part of the minor criteria for the diagnosis, the etiopathogenesis has not been examined. The purpose of the suggested study is to evaluate and characterize the anatomical and biochemical changes in the muscles of the thigh and in the ankle triggered by physical activity in FMF patients complaining of exertional lower leg myalgias and edema after minor physical exercise.
