Active clinical trials for "Communicable Diseases"

To evaluate the clinical, immunologic, and virologic effects of oral zidovudine (AZT) plus intravenous immunoglobulin (IVIG) versus AZT plus placebo (albumin). It is estimated that by 1991, there may be 10,000 to 20,000 HIV-infected children in the United States. HIV infection in children is most often associated with symptomatic disease and poor prognosis. Treatment with antiviral therapy may be effective in changing the course of disease and decreasing mortality in this vulnerable population. AZT treatment has been shown to decrease mortality and the frequency of opportunistic infections in certain adult AIDS patients; therefore, it is likely that children may also benefit from this antiviral therapy. In addition, bacterial infections are frequently found in HIV-infected children. Because pooled human serum immunoglobulin, another name for antibodies, is effective in reducing bacterial infection in patients with defects of immunity, it may reduce the rate of bacterial infection in HIV-infected children as well. In this study, AZT will be administered together with IVIG to determine safety, tolerance, and efficacy of the combined treatment.

The researchers collect patients who accepted eradication program of the helicobacter pylori but failed to eradicate helicobacter pylor from the outpatient clinic. After rescue therapy, evaluating the effect of retreatment interval on eradication effect of Helicobacter pylori infection.

This is a multicenter, randomized, double-blind, placebo-controlled, multiple-ascending dose phase Ib study of HH-003 injection, which is a monoclonal antibody targeting Hepatitis B virus. This study aims to evaluate the safety, tolerability and pharmacokinetics of HH-003 injection in treatment-naive participants chronically infected with hepatitis B virus.

The study will evaluate the efficacy and safety of Broncho-munal®, capsules, 7 mg (Sandoz dd, Slovenia) versus Placebo in the treatment of patients with acute uncomplicated respiratory tract infections.

The aim is to study the association of H. pylori infection with T2DM and its relation with glycated hemoglobin (HbA1c) levels

This study aims to compare the recurrence rates of Esomeprazole and Lansoprazole in triple combination therapy to eradicate H.pylori infection in children. The participants were divided into two groups, those who received Esomeprazole and those who received Lansoprazole

The aim of the study is to evaluate the effectiveness of Hypochlorous Acid and Chlorhexidine as postsurgical antimicrobial agents in the treatment of severe chronic periodontal disease. The selected patients will be randomly divided into two groups of 16 each. Subjects in group I will undergo scaling and surgical root planing and will use mouthrinse with 0.05% HOCl for 7 days, after this they will mouthwash with 0.025% HOCl until day 21 and Subjects in group II will undergo scaling and surgical root planing followed by a rinse with CHX 0.2% for 7 days, after this they will mouthwash with 0.12% CHX until day 21. Null Hypothesis: There are no significant differences between hypochlorous acid and chlorhexidine in reducing plaque formation at 7, 21 and 90 days of evaluation. There are no significant differences between HOCl and CHX in the elimination or reduction of periodontopathogenic microorganisms at 7, 21 and 90 days. Alternative hypotheses: There are significant differences between hypochlorous acid and chlorhexidine in reducing plaque formation at 7, 21 and 90 days of evaluation. There are significant differences between HOCl and CHX in the elimination or reduction of periodontopathogenic microorganisms at 7, 21 and 90 days.

The incidence and prevalence of nontuberculous mycobacteria (NTM) infections have gradually increased over the years worldwide (1-3). In China, Mycobacterium avium complex (MAC) was the most prevalent NTM specie (4), while challenged by long treatment duration, frequent drug-induced adverse events, lack of treatment alternatives, poor treatment outcome and high recurrence rate (5, 6). In order to maximize the efficacy of the few available drugs and prevent the development of drug resistance, ensuring adequate plasma drug concentrations are of importance. Despite the role of pathogen susceptibility, determined by minimum inhibitory concentration (MIC), is non-negligible, the evidences regarding its association with treatment outcome are limited, especially for rifamycin and ethambutol. The difficulties in explaining the clinical values of MIC might partially be attributed to the lack of in vivo drug exposure data, which cannot be accurately predicted by the dose administered because of between-patient pharmacokinetic variability (7). Therapeutic drug monitoring (TDM) is a strategy to guide and personalize treatment by measuring plasma drug concentrations and pathogen susceptibility, which might have the potential to improve treatment response to MAC lung disease. In this observational study, the hypothesis is that the drug exposure and/or MIC of antimycobacterial drugs are correlated to the treatment response of MAC lung disease, which is assessed from the perspective of treatment outcome, mycobacterial culture negative conversion, lung function, radiological presentation and self-reported quality of life. Consenting adult patients with culture-positive MAC lung disease will be recruited in study hospital. Respiratory samples (sputum and/or bronchoalveolar lavage fluid) will be collected regularly for mycobacterial culture on the basis of BACTEC MGIT 960 system and MIC will be determined using a commercial broth microdilution plate. Drug concentrations will be measured at 1 and/or 6 months after treatment initiation using liquid chromatography tandem mass spectrometry (LC-MS/MS). The final treatment outcome is recorded at the end of MAC treatment and defined according to an NTM-NET consensus statement (8).

The diagnosis of invasive fungal disease remains challenging in the clinical laboratory. The use of matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) for the identification of filamentous fungi as well as its application for antifungal resistance testing and strain typing Will be evaluated.

This is a Phase 2, randomized, parallel-group, double-blind, placebo-controlled, 14-week study designed to evaluate the efficacy and safety of TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) taken once daily at bedtime for the management of multi-site pain associated with Long COVID.
