ABSTRACT
BACKGROUND: Sickle cell disease is a severe genetic disorder, and searching for therapeutic strategies is indispensable for prolonged and improved life for people affected by this condition. OBJECTIVE: This qualitative systematic review aimed to highlight the therapeutic potential of omega- 3 (n-3) in people with sickle cell disease. METHODS: The search was performed by combining sickle cell disease and n-3 descriptors in DeCS/ MeSH databases, including Scopus, PubMed, ScienceDirect, Web of Science, and Virtual Health Library. The risk of bias assessment in the primary studies was performed using the Cochrane risk of bias tool for randomized controlled trials. The evidence quality was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. RESULTS: From the 187 records identified, seven were selected for data collection. Based on the evidence, n-3 supplementation contributes to lower activation of pro-inflammatory biomarkers, improves the concentration of docosahexaenoic and eicosapentaenoic acids in the erythrocyte membrane, provides better hemostatic response, and helps in vaso-occlusive crisis, pain episodes, and hospitalization reduction. CONCLUSION: The findings suggest that n-3 adjuvant therapy favors the clinical and general aspects of people with sickle cell disease.
ABSTRACT
BACKGROUND: HIV infection affects millions of people globally. Currently, although several drugs have brought an improvement in the quality and life expectancy of these individuals, they are accompanied by several adverse effects. OBJECTIVE: To conduct a systematic review of studies examining the relationship between antiretroviral therapy (ART) uses and secondary dyslipidemia. METHODS: The review followed the criteria defined by PRISMA. Only articles that completely evaluated the lipid profile were included, which consisted of total cholesterol (TC), triglycerides (TG), and LDL cholesterol (LDL-c), HDL cholesterol (HDL-c). RESULTS: It was observed that the use of nucleoside and non-nucleoside reverse transcriptase inhibitor (NNRTI and NNRTI respectively) drugs and protease inhibitors are the most used in ART and are associated with changes in lipid profiles. The main changes observed were increases in TC, TG, and LDL-c in addition to a decrease in HDL-c. These patients had a higher risk of developing cardiovascular disease not only due to the use of therapy, but also due to the presence of other comorbidities evaluated in these studies, such as obesity, diabetes, and hypertension. The increase in age, the difference between genders, CD4 T-cell count, and viral load, were observed as risk factors for worsening dyslipidemia. CONCLUSION: According to the findings of this study, anti-HIV therapy is linked to dyslipidemia, which may or may not be the primary cause, and is frequently connected with a number of metabolic problems that can exacerbate the illness.
