Active clinical trials for "Infections"

Enterobacterales resistant to carbapenem are cause of severe concern in hospital-acquired infections since therapeutic options are limited. Recently approved drugs, such as bela-lactam/beta-lactamase inhibitor, have been the drug of choice. However, its use is limited in low- and middle-income countries. Thus, therapy of these infections mostly relies on polymyxins and other old drugs. The role of adjuvant carbapenem therapy in combination with polymyxins, aminoglycosides and other drugs is under investigation. From a pharmacokinetic/pharmacodynamic (PK/PD), there is an elevated probability that high-dose, extended infusion administered meropenem reach the PK/PD target of 40% above the minimal inhibitory concentration (MIC) of the pathogen when the MIC is 32mg/L or lower (non-susceptible isolates have MICs of 4mg/L or higher). However, the MIC is not routinely determined in clinical laboratories. In addition, high-level (above 32mg/L) resistance to carbapenems have been reported in many studies. This open-label, randomized clinical trial aim to assess if the addition of meropenem to the best available therapy can increase the number of days alive and free of hospitalization in patients with bloodstream infections by Enterobacterales with MIC of meropenem above 32mg/L.

Study Objective: To test if early preemptive hydroxychloroquine therapy can prevent disease progression in persons with known symptomatic COVID-19 disease, decreasing hospitalizations and symptom severity.

None of the vaccines approved, or in clinical trials, have so far been tested on transplanted patients. If they produce an immune response to the Spike protein of SARS-CoV-2 it is unknown how long the protective immunity will last. Not all immune responses are equal. The investigators will quantify immune cell subsets with flow and mass cytometry analyses to describe the phenotype of responding immune cells, including specific T cells. If not already established, patient human Leukocyte antigen (HLA) genotypes will be typed. In order to compare the immune responses with healthy individuals a control group of hospital employees will be included and sampled before and after vaccination according to the same time schedules as the kidney transplanted patients.

Treatment of patients hospitalised for management of moderate COVID-19 infection

This study will evaluate the effect of PF-04136309 in patients with chronic hepatitic C virus infection and abnormal liver enzymes.

Recurrent CDI is a growing problem with few treatment options that provide lasting effect. Fecal transplantation has been shown in several case series to be successful in controlling recurrent CDI. The current study is a non-blinded, randomized controlled trial comparing fecal transplantation with a 6 week taper of oral vancomycin for the treatment of refractory CDI. Approximately 146 patients will be enrolled over one year. Participants in the study will be followed for 120 days, and will be given the opportunity to cross over to the alternative intervention arm if a relapse in symptoms occurs. The primary outcome measure will be recurrence of toxin-confirmed CDI within 120 days of starting the intervention. Secondary outcomes include: early recurrence of symptoms within 14 days, relapse within 120 days (same strain of C. difficile), attributable mortality, hospitalization and serious adverse events.

The purpose of this study is to evaluate the safety and tolerability of doripenem compared to cefepime in children hospitalized with complicated urinary tract infections.

Purpose: This is a pilot study to evaluate HIV viremia and persistence in acutely HIV infected antiretroviral naïve patients treated with Darunavir/ritonavir and Etravirine Participants: 20 participants, age 18 and older, HIV infected, antiretroviral naïve patients Procedures (methods): ARV treatment with Darunavir/ritonavir and Etravirine, Optional studies: Genital secretion samples, Cerebrospinal fluid samples, Leukapheresis, Endoscopy/colonoscopy

Thrombocytopenia occurs when a person's blood has a decreased number of platelets, which are cells involved in blood clotting. This condition may lead to uncontrolled bleeding and can be fatal. Thrombocytopenia commonly occurs with hepatitis C virus (HCV) infection or as a result of standard HCV treatment. Anti-D is an antibody approved by the Food and Drug Administration (FDA) for the treatment of HIV-related thrombocytopenia. The purpose of this study is to determine the safety and effectiveness of intravenous anti-D for the treatment of thrombocytopenia in patients with HCV infection who are starting or already undergoing treatment with peginterferon alfa-2 and ribavirin. This study will recruit HCV patients both with and without HIV co-infection.

This study will examine the safety and effectiveness of ranitidine (Zantac) in patients with Hyper-IgE recurrent infection syndrome, a disease characterized by recurrent infections of the ears, sinuses, lungs and skin, and abnormal levels of the antibody immunoglobulin E (IgE). Patients age 2 and older who have Hyper-IgE recurrent infection syndrome and who have had chronic or frequent infections in the last 12 months may be eligible for this study. Participants are randomly assigned to take ranitidine or placebo in pill or liquid form twice a day for 12 months. In addition to treatment, patients undergo the following procedures during visits scheduled on day 0 of the study (baseline) and at 3, 12, 15 and 24 months. Evaluations at 6, 9, 18 and 21 months are by telephone. Medical history and physical examination - baseline and 3 and 24 months. Clinical severity score - baseline and 3, 6, 9, 12, 15, 18, 21 and 24 months. Dermatology exam - baseline and 3, 12, 15 and 24 months. Pulmonary function test - baseline and 12 and 24 months. Chest CT - baseline and 12 and 24 months. Quality of life assessment - baseline and 3, 12, 15 and 24 months. Pregnancy testing - baseline and 3, 12, 15 and 24 months. HIV test - baseline and 12 and 24 months. Contraception evaluation - baseline and 3, 6, 9, 12, 15, 18, 21 and 24 months. Missed school/work days assessment - baseline and 3, 12, 15 and 24 months. Medication adherence - baseline and 3, 6, 9, 12, 15, 18, 21 and 24 months. In addition to the above procedures, participants who are not enrolled in study 00-I-0159 have a baseline scoliosis series and genetic consult.
