ABSTRACT
Physicians play a key role in the accuracy of bacteriological results by appropriate prescription and the quality of sample collection, preservation and transport. Samples for diagnostic purposes are of use if analysis results have an impact on the therapeutic approach. They have minimal risk of contamination, are usually obtained invasively, and may be targeted to detection of specific bacteria. Physicians should refer to the laboratory technical manual to provide proper sample quality. Furthermore, they have to provide clinical and administrative information to the microbiologist, because the laboratory analytical process depends on these. Close collaboration between physicians and microbiologists is essential.
Le médecin contribue considérablement à la fiabilité des résultats de bactériologie par l'adéquation de sa prescription, la qualité de son prélèvement, de son conditionnement et de son transport. Un prélèvement à visée diagnostique est utile si le résultat de l'analyse influe sur l'attitude thérapeutique. Il présente un risque de contamination minimal, est généralement obtenu de manière invasive, ou est destiné à la recherche de germes désignés. Pour la prise en charge correcte des échantillons, le médecin se référera au guide technique du laboratoire. De plus, il veillera à fournir au microbiologiste les renseignements cliniques et administratifs, puisque d'eux dépend la démarche analytique opérée au laboratoire. Une collaboration étroite entre médecins et microbiologistes est décisive.

Antiretroviral therapy (ART) has improved quality of life and increased life expectancy of HIV-infected individuals. Opportunistic diseases are less common, and mortality has declined. Consequently, patterns of mortality and morbidity are changing among the HIV-positive population. The focus of care has shifted to ART-related problems and to various non-AIDS diseases. Such comorbidities, often occurring sequentially or concurrently, may be the consequences of long term ART toxicity, a state of chronic inflammation due to HIV infection, lifestyle-related risks for disease, and aging. The emergence of non-AIDS related conditions highlights the important role of primary care physicians, especially of those with extensive experience in HIV management.
