IntroductionThe evidence on the relationship between breast cancer and different types of antihypertensive drugs taken for at least 5 years is limited and inconsistent. Furthermore, the debate has recently been fueled again with new data reporting an increased risk of breast cancer among women with a long history of use of antihypertensive drugs compared with nonusers.MethodsIn this case-control study, we report the antihypertensive drugs–breast cancer relationship in 1,736 breast cancer cases and 1,895 healthy controls; results are reported stratifying by the women’s characteristics (i.e., menopausal status or body mass index category) tumor characteristics and length of use of antihypertensive drugs.ResultsThe relationship among breast cancer and use of calcium channel blockers (CCB) for 5 or more years had odds ratio (OR) = 1.77 (95% CI, 0.99 to 3.17). Stratifying by BMI, the OR increased significantly in the group with BMI ≥ 25 (OR 2.54, 95% CI, 1.24 to 5.22). CCBs were even more strongly associated with more aggressive tumors, (OR for invasive tumors = 1.96, 95% CI = 1.09 to 3.53; OR for non ductal cancers = 3.97, 95% CI = 1.73 to 9.05; OR for Erbb2+ cancer = 2.97, 95% CI: 1.20 to 7.32). On the other hand, premenopausal women were the only group in which angiotensin II receptor blockers may be associated with breast cancer (OR = 4.27, 95% CI = 1.32 to 13.84) but this could not be identified with any type or stage. Use of angiotensin-converting-enzyme inhibitors, beta blockers and diuretics were not associated with risk.ConclusionsIn this large population-based study we found that long term use of calcium channel blockers is associated with some subtypes of breast cancer (and with breast cancer in overweight women).

Introduction: Although HAART cannot eradicate HIV, it suppresses viral replication, resulting in a progressive reduction in HIV-related morbidity and mortality. The increase in life expectancy for HIV-infected patients has turned this disease into a chronic disease and, therefore, to the appearance of comorbidities. At the same time there is an increase in the use of concomitant medication, making HIV-infected patient a polymedicated patient. Objective: To determine the degree of polypharmacy and to describe clinically relevant drug interactions, as well as the comorbidities and adherence to HAART in HIV + patients over 50 years. Methods: Observational, transversal study. Patients ≥50 years on HAART ambulatory were included. The variables were collected: aged, sex, VL, CD4, comorbidities, ARV, concomitant medication, herbal products and adherence. Patients who did not sign informed consent were excluded. Results: Were included 154 patients ≥50 years on HAART. The presence of polypharmacy, defined as the use of 5 or more medications including HAART, was 40.3%. 73.4% of the patients had concomitant medication: lipid-lowering agents (33.8%), anxiolytics / sedatives (28.6%), proton-pump inhibitors (26.0%) antihypertensive agents (23.4%). 102 relevant interactions were recorded, finding statistically significant differences in relation to the presence of polypharmacy and pharmacologic drugs classes (p <0.001). Conclusion: The prevalence of polypharmacy among HIV+ patients ≥50 years is high. Comorbidities, interactions and drugs associated were similar to those described in the literature. It is necessary to establish priorities in relation to drug interactions with polypharmacy and a correct approach to the pathologies that may develop.

Patients consider treatment with a powerful, long-lasting and well-tolerated ART a priority and among their preferences for different treatment regimes, once-daily dosing regimes are highlighted. The ARPAS study showed a direct relationship between compliance and satisfaction with ART, and between compliance and quality of life, in a manner that the strategies improving compliance must necessarily include aspects that allow them to improve patient satisfaction with treatment and quality of life.

The ESTAR turns out to be a suitable, reliable instrument for evaluating satisfaction with ART by HIV+ patients.

The PC situation of HIV patients is of a good standard, but there is still a lot to be done to achieve acceptable, quality PC.
