Active clinical trials for "Communicable Diseases"

Serum samples will be corrected twice from the same youth subjects with one year interval. Seroincidence of pertussis will be estimated by the elevation of Ig-G-PT in paired sera from an identical individual. The relationship between the incidence and the demographic data or medical history of the subjects will be discussed.

Hospital-acquired infections are common complications in preterm infants. The diagnosis has to be fast and accurate. Indeed, the early identification of a suspected infection is very important, since the early administration of antibiotics lowers the risk of septic shock and improves long term outcome in the infected newborns who survive. Besides, a high specificity in the diagnosis of infection allows for the reduction of inappropriate treatment and thus prevents the emergence of antibiotic resistance. The aim of this study is to develop a computer-assisted diagnosis tool, based on the real time analysis of cardio-respiratory signals, to aid the neonatologist in the diagnosis of infection of the preterm infant, at the bedside.

The purpose of this trial is to determine if exposure to ARV-containing investigational products in IPM clinical trials will impact the natural history of HIV infection as measured by the virologic, immunologic and clinical outcomes of participants who become HIV-positive during the IPM 027 trial.

Introduction: Periprosthetic joint infection (PJI) is a common cause for reoperation after knee and hip arthroplasty surgery. Debridement, antibiotics and implant retention (DAIR) is recommended in early infections (< 4 weeks) and stable implants. Aims: To define the success rate of DAIR in early infections and to identify predictors for success. Material and methods: In a retrospective cohort study we included patients with hip- or knee arthroplasties reoperated for an early PJI at Danderyd Hospital 2007-2012. Logistic regression analysis was used to identify risk factors affecting success rate. Primary outcome variable was the success of the DAIR treatment. Secondary outcome variable vas risk factors for treatment failure.

Cervical cancer is a public health problem. In term of frequency and mortality, it represents in Martinique the third localization the most frequently diagnosed and the fifth cause of death by cancer. Cervical cancer is recognized as viro-inducted. Human papillomavirus (HPV) is the etiologic agent, as a necessary but not sufficient cause, in the cancer genesis. It is estimated than about 70 to 80% of women have been or will be infected with an HPV in their genital life, the risks factors being those of the others sexually transmitted diseases (STD). Most of HPV infection are transient, by spontaneous clearance in a few months of the virus under episomal form. Carcinogen risk is related to viral persistency which inducts the condition of cellular transformation. Infection persistency and subsequent carcinogen risk depend of the genotype concerned and of the host immunitary response. HIV infection is known to be associated with an higher prevalency of one or several infection with HPV-HR. However, no data about HIV/HPV coinfection prevalency are available nowadays in French overseas department of South America whereas they are the most affected by HIV.

Infections are the most feared complications developing in patient who had had kidney transplantation. The aim of this study is to document the local disease pattern among this group of patients.

Advances in HAART have been a huge success story in the management of HIV infection. However, serious metabolic complications including osteoporosis and bone fractures are increasingly been seen with HAART, and the responsible mechanisms remain poorly elucidated. The skeleton continually regenerates through homeostatic bone remodeling. Osteoclasts the cells responsible for bone resorption form under the influence of the key osteoclastogenic cytokine Receptor- Activator of NF-KB (RANKL). The osteoclastogenic and pro-resorptive activities of RANKL are moderated by its physiological decoy receptor osteoprotegerin (OPG). Increase in the ratio of RANKL to OPG accelerates the rate of osteoclastic bone resorption leading to osteoporosis. The investigators' preliminary studies have now demonstrated that in an animal model of HIV/AIDS, the HIV-1 Transgenic rat, the development of osteoporosis is recapitulated as observed in human patients. Furthermore, the investigators found that B cell expression of OPG is significantly downregulated, concurrent with a significant upregulation in production of RANKL.

Cytomegalovirus (CMV) is a common cause of illness in patients who have undergone a transplant. Serious infections due to CMV can affect many parts of the body including the lungs, the gut, and the liver. Since transplant recipients are at risk for CMV or have evidence of infection with CMV, they are given an antiviral drug (usually ganciclovir or valganciclovir). Despite this, there are a chance that CMV infection may cause problems in the future. The purpose of this study is to assess how well patients'immune systems responds to the CMV virus, so that in the future it may be possible to predict which patients are at highest risk of CMV.

The primary objective is to study the value of serum procalcitonin as a predictive marker for severe bacterial infection in febrile infants. 2200 febrile infants aged less than 3 months will prospectively be included. All infants will have a measure of Procalcitonin concentrations. Comparison of the mean value of Procalcitonin concentration in infants with and without serious Bacterial infection. Evaluation of the area under the ROC for Procalcitonin concentration.

The purpose of this study is to identify risk factors associated with indwelling urinary catheters, as well as to assess the nurses' knowledge and adherence to hospital policies. The study will also include a very extensive literature search in an attempt to create a national standard or guideline.
