Active clinical trials for "Communicable Diseases"

Urinary infections in children is very common. Delay in the diagnosis may be followed by complications. Pyelonephritis is a febrile urinary infection with a renal injury. In local experience, about 30-40% of the children don't have an inflammatory syndrome or echographical abnormalities. Do they really have a renal injury ? In fact, only the scintigraphy or the Magnetic Resonance Imaging (MRI) may show these lesions, but are done only in specific cases (diagnosis of uropathy or nephropathy). Recent studies have shown that plasmatic Neutrophil Gelatinase-Associated Lipocalin (NGAL) is associated traumatic or inflammatory renal lesions. But the plasmatic NGAL cutoff is fluctuant depending on the cohorts and gold standards. The main goal is to evaluate a new methodology of dosing NGAL, (immuno-dosage turbidimetric dosage). The investigators suppose that plasmatic NGAL protein will detect renal injury, which would be confirmed by MRI. The aim of this study is to evaluate the area under the curve (AUC) of plasmatic NGAL protein with an automatised method, for the detection of renal injury. This would be confirmed by reno vesical MRI, in children over 2 years old with febrile urinary infections

The purpose of this study is to compare the outcomes of two different treatment options commonly used to manage periprosthetic joint infection (PJI), an infection around the artificial knee or hip.

This is a multi-center randomized controlled evaluator-masked trial designed to compare metagenomic deep sequencing (MDS) versus standard of care testing for improvement of outcomes for intraocular infections. Patients with presumed intraocular infections who meet the eligibility criteria will be randomized to receive MDS testing results or not to receive MDS testing results. All patients will receive standard-of-care testing to guide management. Enrolled patients will be followed at week 2, week 3-6 (randomization visit), and at 4 weeks after the randomization visit. The proportions of patients who received the appropriate therapy and the proportions of patients with improved outcome will be compared between arms. Patient quality of life, MDS performance, and the provider certainly of belief will be collected.

The study is a cluster randomized controlled trial developed in counties located in Appalachia and the Midwest. Counties are selected to have high risk for HIV and HCV infection associated with injection drug use.

Colorectal cancer in periooperative period patients (n=60) will be enrolled to this study. Participants will be divided into 4 groups as follows: group 1 (n=15) will receive 2 capsules (per day) of L. plantarum 299v L. plantarum 299v (Sanprobi IBS®) for 4 weeks group 2 (n=15) will receive L. plantarum 299v (2 capsules per day) and inulin (4 g) for 4 weeks group 3 (n=15) will receive placebo (2 capsules per day) and inulin (4 g) for 4 weeks group 4 (n=15) will receive placebo (2 capsules per day) for 4 weeks

Helicobacter pylori (H. pylori) is a gram-negative flagellated bacterium that inhabits the gastric environment of 60.3% of the world population, and its prevalence is particularly high in countries with inferior socioeconomic conditions, exceeding 80% in some regions of the globe , This phenomenon occurs among other reasons, due to the unsatisfactory basic sanitation and high people aggregations observed in many under developed nations, scenarios that favour the oral-oral and fecal-oral transmissions of H.pylori.Another possible transmission route of this pathogen is the sexual route. Several studies have shown that the colonization of H.pylori could be negatively and positively associated with the induction and progression of several diseases .It has been reported to be linked to gastric and duodenal ulcer, gastric carcinoma, and gastric mucosa-associated lymphoid tissue (MALT) lymphoma and gastritis ,A positive association also reported between H.pylori infection and oesophageal cancer. Moreover, evidence is also available on the positive association between H.pylori and non gastrointestinal diseases such as diabetes mellitus , coronary artery disease , and anaemia. Abdominal pain and discomfort, nausea, burping, and loss of appetite are common symptoms of H.pylori infection. Other symptoms include, bloating, weight loss, and heart burn. Several approaches are used in the detection of H. pylori. Both the invasive and the non-invasive methods are employed in the detection of H. pylori in a patient. Many factors, however, influence choices in the method of diagnosis: availability of diagnostic instruments/materials, sampling population, and competency and experience of the physicians/clinicians . Invasive methods include endoscopic evaluation, histology, rapid urease test (RUT), and bacterial culture. Non-invasive methods include urea breath test (UBT), stool antigen test (SAT), serology, and molecular diagnostic approaches .Endoscopy is an accurate test for diagnosing the infection as well as the inflammation. Endoscopy also allows the determination of the severity of gastritis with biopsies as well as the presence of ulcers, MALT lymphoma and cancer. Real-time endoscopy along with conventional white light imaging (WLI)and image enhanced endoscopic (IEE)techniques, such as narrow-band imaging (NBI), linked color imaging (LCI) and blue laser imaging (BLI), appear to have important roles in clinical practice to identify H. pyloriinfected status . Another endoscopic technique is i-scan digital chromoendoscopy, which is a digital contrast method that enhances minute mucosal structures and subtle changes in color . The overall diagnostic accuracy of i-scan is 97% compared to 78% for WLI .

SMA (Spinal Muscular Atrophy) is a rare neuromuscular disease characterized by motoneuron damage. Symptoms consist of respiratory involvement with numerous respiratory infections and eventually respiratory failure, for which NIV (Non Invasive Ventilation) is often used. Ventilation machines are in close contact with the respiratory tract of patients. They contain heated water to humidify the circuit. These humid and warm environments are conducive to the development of bacteria such as Pseudomonas aeruginosa. In this context, it is interesting to look for the presence or absence of bacteria, in comparison with the respiratory ecology of the patients. The aim is to highlight the microbiological role of NIV on the occurrence of respiratory bacterial infections or secondary infections in patients with SMA. To do this, samples are taken from the machines, and ECBCs are performed on patients during respiratory physiotherapy sessions.

This is a Prospective, multi-center study enrolling adults subjects presented to the ED/Urgent care, with symptoms consistent with lower respiratory infection (LRTI). The reason of this study is to demonstrate the MeMed BV can help clinicians make decisions about using antibiotics in patients with lower respiratory track infections and see how it would impact clinical outcomes, antibiotics use, hospitalizations, ED clinicians find ways to improve health and medical care.

The goal of this quasi-experimental before/after study without equivalent control group is to to describe the prevalence of frail, pre-fragile and robust individuals in the study group before and after a multifactorial intervention in in frail HIV patients. The main questions it aims to answer are after a multifactorial intervention: To describe the sociodemographic, viroimmunological and ART exposure factors of fragile individuals compared to pre-fragile and robust individuals. To describe adherence to the Mediterranean diet in frail individuals compared to pre-frail and robust individuals. To describe the presence of anxiety and depression in frail individuals with respect to pre-fragile and robust individuals. To describe the analytical parameters and inflammatory markers of frail individuals with respect to pre-fragile and robust individuals. To describe the diversity and composition of the intestinal microbiota of frail individuals with respect to pre-fragile and robust individuals. To describe the body composition of frail individuals with respect to pre-fragile and robust individuals. To describe the factors associated with progression to frailty or robustness after six months of a multifactorial intervention.

Cervical cancer is a relatively common cancer among women living with human immunodeficiency virus (HIV). This study will test women for human papillomavirus (HPV) infection of the cervix. The main purpose of this study is to determine the best way to test for damaged areas of the cervix. Damaged areas of the cervix should be treated and removed to prevent cancer of the cervix. Women in this study will be seen once, twice or three times in a year. Women will provide several samples related to screening for cervical cancer including a swab of the cervix, a self-collected swab of the vagina and urine. Women will have a detailed examination of the cervix called colposcopy and have a few biopsies, or small pinches of the cervix, to look for areas at risk for turning into cancer. If HPV of the cervix is found but treatment of the cervix is not indicated, women will return in 6 months and in 12 months to repeat these tests. Most women will only need 1 visit. Women found to have damaged areas of the cervix at risk for turning into cancer will be referred for treatment. This protocol will compare different tests to understand the best test to identify women at risk for cervical cancer.
