[28] and Murri et al. [25] With regard to ART adherence evaluation, it is important to note that data relevant to the relationship between HRQL and a PI-based regimen were correlated with other researchers’ contribution [13,33] and moreover, are pioneer in our region. In a step-by-step analysis of the various chronic illnesses included in our questionnaire, we found that HIV/HCV coinfection was closely associated with lower scores in the domains of General Health Perceptions, Pain, Physical

Functioning, Social Functioning and PHS. ALK activation There have been few previous investigations of this relationship [34]. Some studies, such as that by Préau et al. [26], did not find a direct correlation between HRQL domain scores and the presence of coinfection. HRQL is influenced by diverse determinants of psychological morbidity, with depression being one of the most important predictive factors [26,35,36]. In our series, depression was significantly associated with HRQL domain scores obtained using the MOS-HIV questionnaire as well as with global indices. We found that patients who were free from depression or had minimal depression had higher scores than other patients. Similar findings have been obtained by other groups [12,13,30,35,37], but never before in our region. A factor that has scarcely been considered in the literature is satisfaction with information received, the evaluation

of which is increasingly Resveratrol important in assessing the quality of medical care. The data obtained

in this study regarding satisfaction with information received are therefore of interest, and are in accordance with the findings of selleck screening library other studies [25,31]. Although there were several potentially confounding factors in the analysis of this variable, we consider it important to present our findings. It is important to evaluate those factors most influential in HRQL and those most likely to receive specific intervention in the clinical care of HIV-infected patients. Perhaps the most novel aspect of this study is the development of a predictive model with which to classify HIV-infected patients in terms of HRQL, which also permits uniform criteria to be used in the care of these patients. We showed, by application of the regression models developed, that the strongest predictive factors for poor overall PHS were female gender and hospitalization in the previous year, and protective factors were having no children and absence of depression. This model explained 83.3% of the variation of PHS with statistic significance. In terms of the overall MHS, significantly protective factors were absence of depression and chronic HCV infection, which explained 88.1% of the variation. In another study carried out in Spain, Ruiz Pérez et al. [13] developed models that explained 34% of the variation in PHS and 33.9% of that in MHS in the HRQL MOS-HIV instrument.
