RESUMO
Background. Immune activation has been implicated in the excess mortality in human immunodeficiency virus (HIV)-infected patients, due to cardiovascular diseases and malignancies. Statins may modulate this immune activation. We assessed the capacity of rosuvastatin to mitigate immune activation in treatment-naive HIV-infected patients. Methods. In a randomized double-blind placebo-controlled crossover study, we explored the effects of 8 weeks of rosuvastatin 20 mg in treatment-naive male HIV-infected patients (n = 28) on immune activation markers: neopterin, soluble Toll-like receptor (TLR)2, sTLR4, interleukin (IL)-6, IL-1Ra, IL-18, d-dimer, highly sensitive C-reactive protein, and CD38 and/or human leukocyte antigen-DR expression on T cells. Baseline data were compared with healthy male controls (n = 10). Furthermore, the effects of rosuvastatin on HIV-1 RNA, CD4/CD8 T-cell count, and low-density lipoprotein cholesterol were examined and side effects were registered. Results. T-cell activation levels were higher in patients than in controls. Patients had higher levels of circulating IL-18, sTLR2, and neopterin (all P < .01). Twenty patients completed the study. Rosuvastatin increased the CD4/CD8 T-cell ratio (P = .02). No effect on other markers was found. Conclusions. Patients infected with HIV had higher levels of circulating neopterin, IL-18, sTLR2, and T-cell activation markers. Rosuvastatin had a small but significant positive effect on CD4/CD8 T-cell ratio, but no influence on other markers of T-cell activation and innate immunity was identified (The Netherlands National Trial Register [NTR] NTR 2349, http://www.trialregister.nl/trialreg/index.asp).
RESUMO
INTRODUCTION: This study aims to ascertain attitudes of health care workers on end-of-life care (EOLC) issues and to highlight the disparity that exists in countries with different backgrounds. METHODS: It is a cross-sectional questionnaire survey across heterogeneous health care providers in India, Chile, the United Kingdom, and the Netherlands using an indigenously prepared questionnaire considering regional variations, covering different areas of EOLC. RESULTS: Of the 109 participants, 68 (62.4%) felt that cardiopulmonary resuscitation should be done selectively, 25 (22.9%) had come in contact with at least 1 patient who had asked them to hasten death, and 36 (33%) felt that training was insufficient to prepare them for skills in issues of EOLC. CONCLUSION: To avoid cumbersome through well-meant interventions, it is important that the caregiving team is aware of the patient's own wishes with respect to EOLC issues.
