Dolutegravir (DTG) is an integrase inhibitor with better lipid profiles than EFV. However, data on treatment experience in Thailand are limited. The primary outcome was lipid profile changes at 24 weeks after switching therapy. Methods: We conducted a prospective, open-label, cohort study in people with HIV aged ≥18 years who had undergone at least 6 months of EFV-based therapy, had HIV-1 ribonucleic acid levels <50 copies/mL for ≥6 months before switching, and were diagnosed with dyslipidemia or had risk factors for atherosclerosis cardiovascular disease based on modified National Cholesterol Education Program Adult Treatment Panel III guidelines. Results: Sixty-four patients were enrolled. The mean age (standard deviation [SD]) was 48.20 ± 10.46 years, and 67.19% were male. At week 24, there were decreases from baseline in mean total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides. However, mean body weight and waist circumference had increased. Conclusions: DTG resulted in better lipid profiles after switching from EFV-based therapy, suggesting that this switch could benefit patients with a high risk of cardiovascular disease.

CVDs are the leading cause of death in the world. In recent decades, investigators have focused their impact on CVD by periodontal disease (PD). PD is a risk factor that can trigger the formation, maturation, and instability of atheroma in the arteries. Two mechanisms have been proposed to explain this relationship: periodontopathic pathogens explicitly invade the circulation or indirectly increase systemic levels of inflammatory mediators. It has been suggested that improvement in disease state has a positive effect on others. This review summarizes evidence from epidemiological studies as well as researches focusing on potential causation channels to deliver a comprehensive representation of the relationship between PD and CVD.","PeriodicalId":11326,"journal":{"name":"Drug Target Insights","volume":"17 ","pages":"31-38"},"PeriodicalIF":2.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/98/61/dti-17-31.PMC9906023.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10688633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We report here a case series of nAMD patients not responding to previous anti-VEGF therapy showing anatomical and functional response to a single intravitreal injection of brolucizumab. Results: Nine patients with nAMD, undergoing treatment with anti-VEGF therapy (aflibercept, bevacizumab, or ranibizumab) but with either fluid persistence or frequent fluid recurrences in retinal compartments, were switched to intravitreal brolucizumab and examined 4 weeks postinjection. No signs of active disease were observed in all but one patient, with complete retinal fluid resolution in seven patients. Central macular thickness and visual acuity significantly improved, and changes were sustained for up to 12 weeks in a subset of three patients. No adverse reactions were observed. Conclusions: This new anti-VEGF drug showed great efficacy since the first week from the injection with a significative reduction of subretinal fluid and rapid improvement of visual acuity. In conclusion, brolucizumab administered intravitreally appears to be an effective treatment in nAMD patients, leading to both early anatomical and functional improvements.","PeriodicalId":11326,"journal":{"name":"Drug Target Insights","volume":"16 1","pages":"6 - 11"},"PeriodicalIF":2.7,"publicationDate":"2022-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46116051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
