Active clinical trials for "Bacterial Infections"

Surgical site infections are an important health indicator for hospitals and a significant medico-economic issue. The aim of the study is to assess the impact of chlorhexidine mouthwash performed before surgery on the bacterial colonization of the pharyngeal mucosa.

Treatment of BV with first deqularum cloride and then followed with clindamycin vaginal Cream.

We propose a randomized controlled trial (RCT) of the Skin intervention, compared to an assessment-only condition (both groups receive rapid HIV testing, a review of testing results, and brief HIV prevention counseling) among 350 injection drug users recruited during an acute medical hospitalization at Boston Medical Center. In the general hospital setting, injection drug users who otherwise might not seek care are accessible and teachable, and the presence of a drug-related illness can set the stage for patients to be more receptive to interventions2. We hypothesize that the Skin intervention will produce better outcomes at 1-, 3-, 6-, 9-, and 12-month(s) post-intervention.

This study will determine whether three manufacturing lots of V419 (PR5I) induce similar immune responses to all of the antigens contained in V419 when given concomitantly with Prevnar13™ and RotaTeq™.

MALDI-TOF MS is capable of directly identifying bacteria and fungi in positive blood cultures, which may be beneficial to patient management. Therefore, MALDI-TOF MS is an important new technology that is becoming routine in developed countries. It is currently unknown whether MALDITOF MS improves diagnostics, costs and patient outcomes in developing countries. This study will assess the clinical impact of a MALDITOF MS system (Maldi Biotyper, Bruker, Germany) in the resource constrained setting of Vietnam and at what cost.

Background: The incidence of gastrointestinal infections is very high. In Western countries at least 30% of the population suffers from at least one food-borne infection per year. Mostly because of the problem of antibiotic resistance, more emphasis is put on prevention of infections. One of the possibilities is to strengthen human resistance to gut infections by consumption of milk ingredients. Aim: To study whether a milk protein concentrate rich in phospholipids improves the resistance of humans to enterotoxigenic E. coli (ETEC). Study design: The MIRAGE study is a parallel, double-blind, placebo-controlled 4-weeks intervention with a milk protein concentrate rich in phospholipids in healthy subjects of 18-55 yrs of age. Participants will be randomly assigned to the milk protein concentrate rich in phospholipids or placebo group (n=30 per group). Subjects will be instructed to maintain their usual pattern of physical activity and their habitual food intake, but to standardize their dietary calcium intake. After an adaptation period of 2 weeks, subjects will be orally infected with a live, but attenuated, ETEC vaccine (strain E1392-75-2A; collection NIZO food research; dose will be 1010 CFU). Before and after infection, an online diary will be kept to record all food and drinks consumption (2x2 days) to assess the habitual dietary intake. The diary will also be used for daily recording of bowel habits and frequency and severity of gastrointestinal complaints. The following biological samples will be collected: 4x10 ml venous blood, a single fecal bolus (for screening) and 7x24 hrs feces. Blood is sampled for immune response analyses and the fecal samples are collected to quantify several infection- and immune system markers and to verify dietary calcium intake. Saliva is sampled three times before and after infection to quantify immune system markers. Primary outcomes: Fecal ETEC excretion and severity of diarrhea (quantified by fecal output per day). Secondary outcomes: Serum immune response to ETEC, self-reported stool consistency scores and gastrointestinal complaints, relative fecal wet weight.

The last decade has witnessed an important reduction of the mortality in children under 5 years but such reduction has not impacted in neonates. Mortality in neonates contributes 40% of all deaths occurring in children below 5 years of age. Severe bacterial disease is among the leading causes of neonatal deaths. Bacterial disease follows bacterial infection. Individuals can be infected without developing disease (carriage stage) but infection is needed to subsequently develop disease. In sub-Saharan Africa, bacterial carriage (i.e. in the birth canal and/or nasopharyngeal tract) is very common in all age groups, with the consequence that occurrence of bacterial disease is one of the highest in the world. Newborns can be infected during labour - when passing through the birth canal - and during the first days/weeks of life, as a consequence of the close physical contact with the mother, if the latter carries bacteria in the nasopharyngeal tract. If the mother is an important source of bacterial infection to the newborn, treating mothers with a powerful antibiotic during labour should decrease bacterial carriage and therefore diminish the risk of bacterial transmission to the newborn during the first days/weeks of life, which should in turn result in the lower occurrence of severe bacterial disease and hence lower mortality. The purpose of this trial is to evaluate the impact of a single oral dose of azithromycin given to women in labour on bacterial carriage of the newborn as well as the women during the first month after delivery. The investigators have selected an antibiotic (azithromycin) that in sub-Saharan Africa has already shown both a strong impact on bacterial nasopharyngeal carriage and on all-cause mortality when administered to everybody in a community (mass drug administration). This specific antibiotic has several advantages for being deployable as a simple intervention in rural Africa, i.e. it requires a single oral administration, it has no special storage requirements and it has the potential to eliminate many of the bacteria commonly causing severe disease in newborn. This clinical trial will be conducted in a peri-urban health facility in Western Gambia. If an impact is shown, the next step would be to conduct a larger study aiming at establishing if the intervention, implemented at a lower level of care (most African women deliver at home assisted by traditional birth assistants), decreases the occurrence of neonatal bacterial disease

After birth, in the presence of risk factors for early neonatal bacterial infection (IBNP), the pediatrician must make a difficult decision quickly or not to prescribe additional examinations and / or hospitalize or not the newborn in order to administer parenteral antibiotics. This decision takes into account several contextual data, (clinical, biological and bacteriological clinical data) to be considered simultaneously. These information lack sensitivity and specificity. Therefore, the common attitude among newborns in many countries remains the achievement of a significant number of additional tests and the establishment, without a prior evidence of infection, intravenous empirical antibiotic therapy for 48 -72h at least in hospitalization. However, the diagnosis of IBNP posteriori, is often reversed. This attitude is: one source to higher health care costs (hospitalization, additional examinations) Selection of the bacterial ecology of the newborn and neonatal services and stress for the newborn and parents

The degree of TH1-skewing by mycobacteria is controlles by NRAMP1 gene polymorphisms and related to the degree of inhibition of TH2-mediated disease.
