Active clinical trials for "Streptococcal Infections"

This study will enroll children ages 5-17 who test positive for Group A Streptococcus (GAS) at a single clinic visit lasting approximately 30 minutes. The primary aim of this study is to assess the accuracy and feasibility of the CandyCollect platform to capture and detect GAS. The investigators hypothesize that the CandyCollect platform is non-inferior to gold-standard rapid antigen detection testing for GAS.

The goal of the study is to investigate, which of two antibiotic treatments - oral penicillin for 10 days or oral cefuroxim for 7 days - is more successful for patients (1-16 years of age) with perianal dermatitis caused by group A beta-hemolytic streptococci.

The purpose of the present study is to assess and compare in healthy non-pregnant women 18 to 40 years of age the safety and immunogenicity of a liquid formulation of Group B Streptococcus (GBS) Trivalent Vaccine (not requiring reconstitution prior to administration), and of the lyophilized formulation of GBS Trivalent Vaccine, administered in non-pregnant and pregnant women in the clinical development program to date.

An interventional, randomized, multicenter, double-blind, placebo-controlled, parallel-group study will be conducted to evaluate the effectiveness of the strain Lactobacillus salivarius V4II-90 in the reduction of Group B Streptococcus (GBS) colonization in pregnant women who are GBS carriers. Forty GBS-positive participants in their first trimester of pregnancy will be randomly assigned to one of the two study groups: The experimental group with 3 months probiotic consumption; and the control group with 3 months placebo consumption. The efficacy of the probiotic strain to reduce the incidence of Group B Streptococcus will be assessed by the percentage of participants with a vaginal and/or rectal detection of Group B Streptococcus at the end of the study, by bilateral comparison of the treatment group with the control group at the same time period. The estimated duration of the study will be 30 weeks, which includes a 3-month product administration. The intervention will start at week 23 ± 4 days of pregnancy and end at week 35 ± 4 days. Then, a visit will be completed one month after delivery.

A Phase I, randomised, single centre, double-blind, placebo-controlled, parallel group study to evaluate the safety, tolerability and immunogenicity of two doses of Group B Streptococcus vaccine.

The purpose of this study is to examine whether daily use of oral gelatin capsules containing dried viable Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 can reduce the GBS colonization rate of vagina and rectum in pregnant women who present with GBS-positive diagnosed by GBS culture at 35-37 weeks gestation. This study is a prospective double blind randomized clinical trial. Vaginal and rectal GBS screening culture are carried out for all pregnant women at 35-37 weeks of gestation in our out-patient department. Subjects with vagina and rectum GBS colonization are invited to participate in our study after informed consent. A total of 200 pregnant women will participate in the study during the 12-months trial period. They are randomly assigned to one of the two groups. The study group is treated with two oral capsules of probiotics once daily (before sleeping) for 14 days, and the control group will take 2 capsules of placebos. Vaginal and rectal GBS culture is repeated for all participators 2 weeks later. All participators will treated according to GBS guideline by CDC in 2002 during laboring.

This is an open-label randomized control trial and feasibility study designed to determine the feasibility of a larger RCT in our setting that would examine prenatal probiotic use in Group B Strep (GBS) positive pregnant women at term. Investigators hope to address the question of whether prenatal oral probiotic use, taken by healthy low risk GBS positive women from approximately 37 weeks gestation until the time of birth, will reduce the number of women who test positive for GBS at the time of admission to Labor and Delivery (L&D).

A subgroup of patients with childhood-onset obsessive-compulsive disorder (OCD) and/or tic disorders has been identified who share a common clinical course characterized by dramatic onset and symptom exacerbations following group A beta-hemolytic streptococcal (GABHS) infections. This subgroup is designated by the acronym PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections). There are five clinical characteristics that define the PANDAS subgroup: presence of OCD and/or tic disorder; prepubertal symptom onset; sudden onset or abrupt exacerbations (relapsing-remitting course); association with neurological abnormalities (presence of adventitious movements or motoric hyperactivity during exacerbations); and temporal association between symptom exacerbations and GABHS infections. In this subgroup, periodic exacerbations appear to be triggered by GABHS infections in a manner similar to that of Sydenham's chorea, the neurological variant of rheumatic fever. Rheumatic fever is a disorder with a presumed post-streptococcal autoimmune etiology. The streptococcal pathogenesis of rheumatic fever is supported by studies that have demonstrated the effectiveness of penicillin prophylaxis in preventing recurrences of this illness. A trial of penicillin prophylaxis in the PANDAS subgroup demonstrated that penicillin was not superior to placebo as prophylaxis against GABHS infections in these children, but this outcome was felt to be secondary to non-compliance with treatment, and there was no decrease in the number of neuropsychiatric symptom exacerbations in this group. In a study comparing azithromycin and penicillin, both drugs were completely effective in preventing streptococcal infections - there were no documented titer elevations during the year-long study period for children taking either penicillin or azithromycin. Comparable reductions in the severity of tics and obsessive-compulsive symptoms were also observed. Thus, penicillin was not performing as an "active placebo" as originally postulated, but rather provided effective prophylaxis against Group A beta-hemolytic streptococcal. Both azithromycin and penicillin appear to be effective in eliminating GABHS infections, and reducing neuropsychiatric symptom severity; thus, between-group differences are negligible. Since increasing the "n" to demonstrate superiority of one prophylactic agent over another would be impractical, we have amended the study design to address two issues: To determine if antibiotics prophylaxis against GABHS infections is superior to placebo in prolonging periods of remission among children in the PANDAS subgroup. To determine if antibiotics prophylaxis against GABHS infections is superior to placebo in improving overall symptom severity for obsessive-compulsive symptoms and tics among children in the PANDAS subgroup. Because penicillin has a narrower therapeutic index and is less expensive than azithromycin, it is the preferable prophylactic agent. Further, penicillin (250 mg orally twice a day) has a long history of providing safe and effective prophylaxis for rheumatic fever and is the first line oral therapy recommended by the American Heart Association. Thus, penicillin has been chosen as the prophylactic antibiotic in the present study. Blister packs are used to increase compliance and to allow for easier documentation of missed doses.

The purpose of this study is to assess the efficacy, safety and tolerability of RX-1741, an oxazolidinone, versus linezolid, another oxazolidinone, in the treatment of uncomplicated skin and skin structure infections

The purpose of this study was to compare the microbiological effects of two different treatments: a single dose of intramuscular benzathine penicillin G (IM BPG) vs. a 10-day daily dose of amoxicillin for the treatment of GABHS pharyngitis in children in low resource settings. This study was a prospective multi-center randomized active control treatment trial. The trial is a non-inferiority equivalence trial, to determine if amoxicillin treatment is at least as effective as the currently given IM BPG treatment.
