Active clinical trials for "Infections"

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.

The purpose of this study is to determine how common oral HPV infections are in college women. The investigators also will find out what risk factors are associated with having oral HPV infections. The investigators hypothesize that approximately 3% of women will have oral HPV, and that HPV will be associated with oral sexual behaviors and with smoking behaviors. Finally, for those women with oral HPV- the investigators will determine whether the infections are persistent (still present) at 3-, 6-, and 12-months after the initial diagnosis.

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 objectives of this study are: To describe the incidence of clinical features in adults with internal ventriculoperitoneal (VP) shunt infections, To determine the validity of laboratory parameters in adults with internal ventriculoperitoneal shunt infections and To evaluate the relationship between the timing of shunt re-implantation with the rates of relapse and secondary infection.

The primary purpose of the study is to evaluate the association of a latent infection of lymphoid cells during the first manifestation of steroid sensitive nephrite syndrome. The thirty nine units of general pediatrics and pediatric nephrite covering the parisian area will participate to the study. We speculate that hybridization of the genome, or a part of the genome, of a virus in lymphoid cells is responsible specific changes of genes expression, leading to the development of the disease.

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.

The purpose of this study is to investigate the expression of protein biomarkers in cervical vaginal fluid in women with preterm premature rupture of membranes (PPROM)
