Screening for neurocognitive impairment, depression, and anxiety in HIV-infected patients in Western Europe and Canada.

CRANIum, a cross-sectional epidemiology study in Western Europe and Canada, was conducted to describe and compare the prevalence of a positive screen for neurocognitive impairment (NCI), depressive symptoms, and anxiety in an HIV-positive population either receiving combination antiretroviral therapy (cART) or who were naive to antiretroviral therapy (ART). HIV-positive patients ≥18 years of age attending a routine medical follow-up visit and able to complete the designated screening tools were eligible for study inclusion. The Brief Neurocognitive Screen was used to assess NCI; depressive and anxiety symptoms were assessed using the Hospital Anxiety and Depression Scale. The evaluable patient population (N = 2863) included 1766 men (61.7%) and 1096 (38.3%) women. A total of 1969 patients were cART-experienced (68.8%), and 894 were ART-naive (31.2%). A positive screen for NCI was found in 41.5% of patients (cART-experienced, 42.5%; ART-naive, 39.4%; p = 0.12). A positive screen for depressive symptoms was found in 15.7% of patients (cART-experienced, 16.8%; ART-naive, 13.3%; p = 0.01), whereas 33.3% of patients screened positive for anxiety (cART-experienced, 33.5%; ART-naive, 32.8%; p = 0.71). A greater percentage of women compared with men screened positive for NCI (51.78% vs. 35.1%; p < 0.0001) and depressive symptoms (17.9% vs. 14.3%; p = 0.01). These data suggest that neurocognitive and mood disorders remain highly prevalent in HIV-infected patients. Regular mental health screening in this population is warranted.

[Retrospective epidemiological study on the durability of the treatment of HIV infection or AIDS in Spain]. / Estudio epidemiológico retrospectivo sobre la duración del tratamiento de la infección por el virus de la inmunodeficiencia humana en España.

BACKGROUND AND OBJECTIVE: To know the durability of consecutive regimens of antiretroviral treatment is important to design a long-term therapy, but there is not much information about this subject. PATIENTS AND METHOD: Retrospective epidemiological study of a sample of 401 patients who began antiretroviral treatment between January 1997 and April 2000 at ten Spanish hospitals. The duration of each consecutive antiretroviral regimen was calculated and the reasons for modification and discontinuation were described. RESULTS: In the 3 years and 3 months covered by the study, 48.6% of the patients received more than one regimen of therapy. Seventy five of the initial prescribed combinations included protease inhibitors. Median duration of consecutive lines of therapy was decreasing: 560, 360, 330 and 202 days for the first, second, third and fourth regimens, respectively. The main reason to modification was intolerance or toxicity (46.2, 49.1 and 47.1% for the first, second and third modification). A fifth of changes was originated by difficulties to follow the therapy. Virological failure was the reason for modification in 21.8, 24.5 and 26.5% of first, second and third changes. CONCLUSIONS: Duration of consecutive antiretroviral regimens progressively decreases. Intolerance or drug toxicity were the main reasons conditioning the change of treatment.
