The management of HIV is mainly represented by its commorbidities (cardio-vascular disease, nephrologic, neurologic, osteo-articular disease, chronic hepatitis and cancer no linked to immunodepression). COPD prevalence has never been studied in HIV population. In consequence, there is no guideline about the screening, treatment or follow-up of COPD in HIV patients. However this population seems particularly at risk to develop COPD because of high tobacco consumption and accelerate ageing. Thus, we need an epidemiologic study to understand the prevalence of COPD in HIV population in order to organize a specific screening and follow-up. This is supported by an improvement of COPD if early managed. On top of that, COPD screening will increase awareness of HIV patients on the problematic of tobacco consumption.
