Active clinical trials for "HIV Seropositivity"

This is a unicentric, two cohorts, observational transversal study. The purpose of this study is to compare the QT/QTc intervals of HIV positive subjects receiving an antiretroviral therapy and those without HIV in an ambulatory care setting.

This study is a Multicentre cohort study with inclusion throughout the full duration of the study. The primary objective is the study of human papillomavirus related genital pathology in HIV positive women. The secondary objective are: To study the characteristics of HPV infection and related disease in the context of long term HAART and HIV infection ; To study the characteristics of atypical cells of uncertain significance detected in Pap smears, whose prevalence has dramatically increased in the last years; To describe cervical cancers observed in the cohort To study the evolution of recurrent high-grade lesions after surgery To describe the evolution of vaginal lesions developed after hysterectomy for high-grade lesions ; To describe the specific aspects of surgery for the treatment of cervical lesions according to the specific localization in the endocervix in HIV-positive women ; To study the in situ T cell HPV specific response in cervical lesions and the relationship between virological and clinical parameters, host immune status and natural history of lesions ; To initiate a prospective study on anal HPV infection and related disease among women infected with HIV. To initiate a study on therapeutic and/or prophylactic HPV vaccines in the context of immunosuppression and a high rate of HPV infection ;

The bacterial diversity of HIV patients digestive microbiota seropositive is poorly understood, it remains to be defined.

An observational retrospective study of NNRTI experienced patients who have virologically failed. The study aims to assess resistance profiling and subsequent prescription patterns of patients on NNRTIs

The investigators are interested in understanding personal factors such as medical conditions and mental health, as well as social and economic factors, that influence marijuana (and other substance) use in HIV-positive patients. Several alternative hypotheses will be evaluated in the proposed project: healthier patients may self-select marijuana use; marijuana use may be associated with consequences that create barriers to seeking healthcare; marijuana use may have medicinal value that reduces the need for such care.

The purpose of this research study is to evaluate how easy it is for female HIV- positive subjects taking Complera to comply with the dietary requirement using a food diary in the short term (4 weeks) and long term (24 weeks and 48 weeks) and to determine association between calorie intake and virologic suppression. A secondary goal of the study is to evaluate subjects' attitudes towards contraception.

The goal of this study is to better understand the factors that might prevent HIV-positive women from having routine pap smear screenings. Researchers also want to learn what might make it easier or encourage women to have these screenings.

The aim of this study was to delineate the epidemiological profile of HIV seropositive patients on antiretroviral therapy at the Clinical Hospital of the Federal University of Goiás.

This retrospective observational study aims at the examination of regional differences in the procedure of referral for serological HIV testing between eastern (new) and western (old) German federal states.

Cerebral small vessel disease (CSVD) is a major cause of cognitive impairment and disability in the general population, secondary to the accumulation of asymptomatic elementary lesions. CSVD is directly correlated with age and cardiovascular risk factors and therefore would be challenging in term of public health care in the future. While HIV patients share the same cardiovascular risk factors and they are often diagnosed with cognitive impairment and frailty, CSVD has not been yet described in this population. The global aim is to compare the prevalence of CSVD in a well controlled HIV+ population compared to HIV- controls matched with age and sex. 500 HIV+ patients and 250 age- and sex- matched controls will undergo a screening of the CSVD with a 10 minutes MRI (FLAIR and T2*). Prevalence of the CSVD will be compared between HIV+ patients and controls. General and HIV-specific parameters from their electronic medical records will be compared between HIV+/CSVD+ and HIV+/CSVD- patients. We are expecting to prove that CSVD is more frequent in HIV+ population.
