Active clinical trials for "Communicable Diseases"

A new paediatric formulation (oral liquid) has been developed for flexible and accurate dosing of valacyclovir in children. To establish the bioavailability of this new formulation, healthy volunteers will be exposed to the new formulation and to valacyclovir tablets. The concentration of valacyclovir in their blood after exposure to the oral liquid will be measured and compared to the tablet.

The purpose of this study is to dermine whether local-water filtered infrared-A (wIRA) irradiation can reduce postoperative wound infection. wIRA irradiation is applied 20min directly preoperatively, before patients underwent abdominal surgery. The wIRA is a harmless light source, that has been described before. We test the impact and clinical outcome of patients undergoing a one-time preoperative wIRA irradiation on postoperative wound healing.

This study specifically seeks to quantify the contribution of relapes to the burden of P. vivax infections and disease by determining on the effect of radical pre-erythrocytic and erythrocytic clearance on subsequent rates of Plasmodium spp. infection and disease in children aged 5-10 years in a treatment to re-infection study design. In order the clear liver-stage/blood-stages G6PD-normal children were randomised to receive Chloroquine (3 days, standard dose) and Coartem (3 days, standard dose) plus either i) primaquine (20 days, 0.5mg/kg) or ii) placebo (20days). These drugs were administered over a period of 4 weeks. In addition to this epidemiological data, the study will assess the natural acquisition of cellular and humoral immune responses to P. falciparum and P. vivax, thus assisting in the determination of correlates of clinical immunity to P. falciparum and P. vivax in PNG children aged 5-10 years. These data will not only be essential for development of future vaccines against P. vivax and P falciparum but provide invaluable insight into the contribution of long-lasting liver-stages to the force of infection with P. vivax that will contribute towards designing more rational approaches to the treatment of P. vivax both in the context of case management and future attempts at elimination.

The overall goal of this study is to investigate whether the modulatory effects of probiotics, which are used as food supplements (Lactobacillus GG marketed as Culturelle or yoghurt) in the gastrointestinal tract promote restoration of intestinal function and enhance the specific immune response in children with cryptosporidial or rotaviral infections in South India. Rotavirus and Cryptosporidium spp. are the most important viral and parasitic causes of gastroenteritis in children in south India. Both infections can lead to severe dehydrating gastroenteritis in young children and have no specific treatment. Repeated episodes of diarrhea can result in long term deleterious effects on nutritional status, possibly due to intestinal damage. Most episodes of infectious gastroenteritis resolve without specific therapy, the mainstay of treatment being rehydration. However, oral rehydration remains under-utilized, in part due to the lack of effect on frequency of bowel movements and duration of illness. Due to the interest in simple, safe and effective measures to ameliorate the long-term effects of diarrheal illness, there is a growing appreciation for the potential of certain microorganisms to offer direct benefits to the health of a host. Probiotics are known to beneficially modulate several host functions, the most important of which are immune responses and intestinal barrier integrity. The investigators propose to build on the investigators previous collaborative efforts to conduct pilot studies to provide a mechanistic understanding of the effect of probiotic supplementation in children with rotaviral and cryptosporidial diarrhea. Based on the established efficacy of LGG for the treatment of a variety of diarrheal diseases and the documented modulation of immune responses and strengthening of intestinal epithelial barrier function by probiotics, the investigators propose to conduct a Phase I/II double-blind randomized placebo controlled clinical trial to assess the preliminary efficacy and safety of LGG vs. placebo in the resolution of symptoms and restoration of intestinal function in children with either rotaviral or cryptosporidial diarrhea and no other detected enteric infection. Promising results in this Phase I/II study will provide preliminary data to power a future randomized trial on these critical outcomes following rotaviral or cryptosporidial infection.

Main aim and objective The aim was to present the treatment of infectious diseases in elderly, especially in nursing homes and further to evaluate the effect of an intervention package aiming at improving treatment with antibiotics in Swedish nursing homes Specific objectives Present the treatment patterns regarding infectious diseases, including gender aspects in elderly, especially in nursing homes. Through focus group discussions elucidate the decision making process in nursing homes and target the intervention. Based on the above information develop an educational intervention to contribute to the improvement of the prescribing of antibiotics in nursing homes Evaluate the effect of the intervention on quality of prescribing, knowledge and attitudes in relation to available guidelines

The primary objective of this study is to measure the penetration of ceftobiprole into subcutaneous (s.c.) adipose tissue and skeletal muscle and to determine the concentration over time of ceftobiprole in these tissues and in plasma after administration of a single intravenous (i.v.) infusion (directly into the vein) of ceftobiprole 500 mg administered over 2 hours. The secondary objective was to further assess the safety and tolerability of ceftobiprole after a single i.v. infusion.

This is a research study designed to look at the pharmacokinetics (distribution, breakdown, and removal) and tolerability of a single dose of daptomycin in patients aged 2 to 6 years who have infections that are caused by a specific group of bacteria (called Gram-positive bacteria).

RATIONALE: Antifungals such as voriconazole may be effective in controlling fungal infections. Combining voriconazole with interferon gamma may be more effective than voriconazole alone in treating fungal infections. PURPOSE: Randomized phase II trial to compare the effectiveness of voriconazole with or without interferon gamma in treating patients who have aspergillosis or other fungal infections.

RATIONALE: Giving antibiotics may be effective in preventing or controlling early infection in patients with multiple myeloma and may improve their response to chemotherapy. PURPOSE: This randomized clinical trial is studying antibiotics to see how well they work compared to no antibiotics in preventing early infection in patients with multiple myeloma.

Foods in the human diet can affect the development of diseases over time, such as diabetes or heart disease. This is because the amount and types of foods in the diet eat can affect a person's weight, and because different foods are metabolised (processed) by the body in different ways. Scientists have also found that the bacteria in the human gut (the gut microbiome) affect their metabolism, weight and health and that, together with a person's diet and metabolism, could be used to predict appetite and how meals affect the levels of sugar (glucose) and fats (lipids) found in blood after eating. If blood sugar and fat are too high too often for too long, there is a greater chance of developing diseases such as diabetes and cardiovascular disease. The gut microbiome is different in different people. Only 10-20% of the types of bacteria found in the human gut are found in everyone. This might mean that the best diet to prevent disease needs matching to a person's gut microbiome and it might be possible to find personalised foods or diets that will help reduce the chance of developing chronic disease as well as metabolic syndrome. The study investigators are recruiting volunteers aged 18-70 years to take part in a study that aims to answer the questions above. Participants will be asked to consume standardised meals on up to 8 days while wearing glucose monitors (Abbott Freestyle Libre) to measure their blood sugar levels. Participants will also be required to prick their fingers at regular intervals to collect small amounts of blood, and to record their appetite, food, physical activity and sleep using apps and wearable devices. They will be asked to collect a fecal and saliva sample before consuming the standardised meals, and to provide a fasted blood sample at the end of the study period.
