Active clinical trials for "Communicable Diseases"

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.

A bacterial infection of an artificial joint is a serious complication that often requires additional surgery to exchange the arthroplasty. It is also difficult to recognize an infected joint, as the symptoms caused by the infection are very similar to those of other problems with arthroplasties, such as loosening of the implant. To improve the ability to diagnose prosthetic joint infections, this study compares the levels of calprotectin, a specific inflammatory protein, in the joint fluid of infected joints and joints with other complications. The underlying hypothesis is that the level of calprotectin in infected joints is significantly higher, thus facilitating the diagnosis of prosthetic joint infection.

Clostridioides difficile infection (CDI) is one of the most common hospital-acquired infectious diseases with a high mortality rate (6-30%). The treatment of CDI, especially the recurrent form of the disease is still considered a challenge. The FILTRATE randomized controlled trial aims to investigate the safety and efficacy of fecal filtrate transplantation in the treatment of recurrent CDI and compare it with conventional fecal microbiota transplantation (FMT).

This study is designed to compare the performance of the NOWDx Syphilis Test to a currently marketed device. The intent is to show the rapid test device is comparable to the currently marketed device. The NOWDx Syphilis Test is intended for qualitatively detecting the presence or absence of human antibodies to syphilis in human whole blood to aid in the diagnosis of infection caused by Treponema pallidum.

To improve accurate diagnosis and treatment of common malignant tumors and major infectious diseases in the respiratory system, we aim to establish a large medical database that includes standardized and structured clinical diagnosis and treatment information such as electronic medical records, image features, pathological features, and multi-omics information, and to develop a multi-modal data fusion-based technology system for individualized intelligent pathological diagnosis and therapeutic effect prediction using artificial intelligence technology.

The aim of the study is to evaluate the adverse events and the efficacy of virus specific T lymphocytes selected in vitro from a family donor to treat some refractory viral infections as Adenovirus (ADV), Ebstein Barr virus (EBV), Cytomegalovirus (CMV) that developed in young patients (age between 0 and 21 years) after allogeneic hematopoietic cell transplantation (allo-HSCT) performed at the Transplant Clinical Unit of the IRCCS G. Gaslini Institute (IGG).

The objective of this study is to determine whether oral NAC is effective at attenuating COVID-19 disease symptom severity and duration of symptoms.

The goal of this study is to evaluate the efficacy in preventing HIV infection of the study drugs, lenacapavir (LEN) and emtricitabine/tenofovir alafenamide (F/TAF), in adolescent girls and young women.

A galectin antagonist prevents viral entry of Sars-CoV-2 virus by blocking the specific terminal on the surface receptors that enables the virus to enter human cells. This inhibitor - ProLectin M is a novel substance that is given orally to individuals who have an infection with Sars-CoV-2 or its subsequent mutations causing COVID19 disease. The oral tablet is chewed every hour, for 8 hours daily, for 7 days. We hypothesize that patients receiving the active investigational product (ProLectin M), irrespective of their vaccination status, or underlying medical conditions, will have a faster recovery from COVID19 compared to those receiving its matching placebo. The trial is approved by an Institutional Review Board for safety and all participants will need to provide written informed consent to participate in this trial. The safety of ProLectin M is established as the drug substance is recognised as a safe substance. However, its benefits in relieving patients from the COVID19 infection and providing the patients faster recovery from its clinical symptoms and prevention of delayed sequelae of the infection has not been proven yet.

Total joint replacement (TJR) is an increasing effective procedure in orthopedics. However, TJR failure due to aseptic or septic loosening remains an important problem, often due to predisposing factors of the patient, which determine the need to perform a revision surgery. In light of the recent conclusions emerged on the still open problems concerning the diagnostic accuracy of serum and synovial fluid markers in the diagnosis of peri-prosthetic joint infection (PJI), the project aims at evaluating the diagnostic accuracy and cost-effectiveness of the combination of serum and/or synovial markers in the diagnosis of PJI. Through a diagnostic clinical study on patients hospitalized for revision surgery the project would provide evidences on the potentiality of the combination of some markers in accelerating the PJI diagnosis for the best selection of surgical strategy, choosing the suitable cutoff thresholds to mitigate the effect of some factors on markers' discriminatory capability.
