Background: Real-world vaccine effectiveness following the third dose of vaccination against SARS-CoV-2 remains less investigated among people with HIV (PWH). Methods: PWH receiving the third dose of BNT162b2 and mRNA-1273 (either 50- or 100-μg) were enrolled. Participants were followed for 180 days until the fourth dose of COVID-19 vaccination, SARS-CoV-2 infection, seroconversion of anti-nucleocapsid IgG, death, or loss to follow-up. Anti-spike IgG was determined every 1–3 months. Results: Of 1427 participants undergoing the third-dose COVID-19 vaccination, 632 (44.3%) received 100-μg mRNA-1273, 467 (32.8%) 50-μg mRNA-1273, and 328 (23.0%) BNT162b2 vaccine and the respective rate of SARS-CoV-2 infection or seroconversion of anti-nucleocapsid IgG was 246.1, 280.8 and 245.2 per 1000 person-months of follow-up (log-rank test, p = 0.28). Factors associated with achieving anti-S IgG titers >1047 BAU/mL included CD4 count 200 copies/mL (aOR, 0.27; 95% CI, 0.09–0.80), having achieved anti-spike IgG >141 BAU/mL within 3 months after primary vaccination (aOR, 3.69; 95% CI, 2.68–5.07), receiving BNT162b2 vaccine as the third dose (aOR, 0.20; 95% CI, 0.10–0.41; reference, 100-μg mRNA-1273), and having previously received two doses of mRNA vaccine in primary vaccination (aOR, 2.46; 95% CI, 1,75-3.45; reference, no exposure to mRNA vaccine). Conclusions: PWH receiving different types of the third dose of COVID-19 vaccine showed similar vaccine effectiveness against SARS-CoV-2 infection. An additional dose with 100-μg mRNA-1273 could generate a higher antibody response than with 50-μg mRNA-1273 and BNT162b2 vaccine.

ABSTRACT: Objectives: We aimed to investigate the evolution of weight, lipid profiles, and glucose homeostasis among virally suppressed people with HIV (PWH) who switched to bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). Methods: PWH with viral suppression who switched to BIC/FTC/TAF in Taiwan between October 2019 and May 2021 were followed for 96 weeks to examine changes in weight, lipid profiles (total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride (TG)), and glycated hemoglobin (HbA1c) levels. Results: 889 PWH with an average weight of 72.1 kg at baseline were included. At week 96, more than 95% of PWH consistently maintained plasma HIV RNA load

From June 2022 to April 2023, 1629 HIV-positive participants were assessed for the risk of atherosclerotic cardiovascular disease (ASCVD). The 10-year ASCVD risk of

Background: While some evidence has suggested the benefits of co-formulated bictegravir, emtricitabine and tenofovir alafenamide (B/F/TAF) in improving the quality of life of people living with HIV (PLWH), patient-reported outcome studies that focus on Asian population remain scarce. We aimed to determine the changes in HIV-related symptom burden in virally-suppressed PLWH switching to B/F/TAF in a real-world setting. Methods: PLWH on stable antiretroviral therapy (ART) for ≥6 months with plasma HIV RNA

Background: To contain the coronavirus disease 2019 (Covid-19) pandemic, non-pharmacologic interventions, including lockdown and social distancing, may have adverse impact on access to HIV testing and care. This study investigated the impact of Covid-19 on HIV testing and care at a major hospital in Taiwan in 2020–2021. Methods: The numbers of clients seeking anonymous HIV voluntary counseling and testing were compared 2 years before (2018–2019) and 2 years after Covid-19 outbreak (2020–2021). People living with HIV (PLWH) who sought care at the hospital during 2018–2021 were included to examine the status of HIV care delivery and disposition. Results: The annual number of HIV screening tests performed had significantly decreased from 2507 to 2794 in 2018 and 2019, respectively, to 2161 and 1737 in 2020 and 2021, respectively. The rate of discontinuation of HIV care among PLWH was 3.7% in 2019, which remained unchanged in 2020 (3.7%) and 2021 (3.8%). The respective percentage of annual plasma HIV RNA testing

Background: A community COVID-19 outbreak caused by the B.1.1.7 SARS-CoV-2 variant occurred in Taiwan in May 2021. High-risk populations such as people living with HIV (PLWH) were recommended to receive two doses of COVID-19 vaccines. While SARS-CoV-2 vaccines have demonstrated promising results in general population, real-world information on the serological responses remains limited among PLWH. Methods: PLWH receiving the first dose of SARS-CoV-2 vaccine from 2020 to 2021 were enrolled. Determinations of anti-SARS-CoV-2 spike IgG titers were performed every one to three months, the third dose of the SARS-CoV-2 vaccine or confirmed SARS-CoV-2 infection. All serum samples were tested for anti-nucleocapsid antibody and those tested positive were excluded from analysis. Results: A total of 1189 PLWH were enrolled: 829 (69.7%) receiving two doses of the AZD1222 vaccine, 232 (19.5%) of the mRNA-1273 vaccine, and 128 (10.8%) of the BNT162b2 vaccine. At all time-points, PLWH receiving two doses of mRNA vaccines had consistently higher antibody levels than those receiving the AZD1222 vaccine (p 141 BAU/mL within 12 weeks, included type 2 diabetes mellitus (DM) (adjusted odds ratio [aOR], 2.24; 95% CI, 1.25–4), a CD4 T cell count 899 BAU/mL within 12 weeks were a CD4 T cell count

Recent outbreaks of enterically transmitted infections, including acute hepatitis A and shigellosis, have raised the concerns of increasing Entamoeba histolytica infection (EHI) among people living with HIV (PLWH) in Taiwan. This study investigated the prevalence of EHI, its temporal trends, and associated factors among newly diagnosed PLWH in Taiwan. Medical records of newly diagnosed PLWH at six medical centers in Taiwan between 2009 and 2018 were reviewed. The annual prevalence of invasive amoebiasis and seroprevalence of E. histolytica were determined and examined by the Cochran-Armitage test. The clinical characteristics associated with invasive amoebiasis and seropositivity for E. histolytica were analyzed in multivariable regression models. Among 5362 patients seeking HIV care at six medical centers in Taiwan during the 10-year study period, 119 (2.2%) had invasive amoebiasis at the time or within six months of their HIV diagnosis. Among 3499 who had indirect hemagglutination antibody (IHA) determined, 284 (8.1%) had positive IHA (≥1:32) and 205 (5.9%) had high-titre IHA (≥1:128). The prevalence of invasive amoebiasis increased from 1.3% in 2012 to 3.3% in 2018 (p = 0.024). Invasive amoebiasis was independently associated with a greater age, men who have sex with men, rapid plasma reagin titre ≥1:4, and concurrent shigellosis and giardiasis. Increasing prevalence of invasive amoebiasis among newly diagnosed PLWH in Taiwan calls for strategies to prevent ongoing transmission in this population. Routine screening of EHI for early diagnosis and treatment is recommended, especially among men who have sex with men and those who present with other sexually or enterically transmitted infections.

Objective: To investigate the prevalence and characteristics of gemcitabine-based chemotherapy-induced thrombocytopenia in Chinese patients with nonsmall cell lung cancer (NSCLC).Materials and Methods: Medical records of 197 patients with histologically proven NSCLC received gemcitabine-based chemotherapy from June 2011 to June 2013 in our hospital were collected. The relative risk factors were identified and evaluated by univariate and multivariate analyses.Results: The incidence of gemcitabine-based chemotherapy-induced thrombocytopenia in these NSCLC patients was 85.8%. Between thrombocytopenia and nonthrombocytopenia patients, in patients with thrombocytopenia and thrombocytopenia, we found Stage III/IV patients got more probabilities for thrombocytopenia (P < 0.01). In addition, patients who received gemcitabine and cisplatin (GP) regimen resulted in more thrombocytopenia than gemcitabine and carboplatin (GC) and other regimens (P < 0.001). In addition, majority of the thrombocytopenia patients presented thrombocytopenia in their first cycle (P < 0.001). Whereas, other potential risk factors such as age, gender, performance status value, diabetes mellitus or not, and other underlying disease (hypertension and hepatopathy) were not showed such significance in this study. Further, the multivariate analysis revealed that stage (odds ratio [OR] 7.113, P < 0.01) and chemotherapy cycles (OR 0.543, P < 0.01) were also statistically significant independent risk factors for gemcitabine-based chemotherapy-induced thrombocytopenia.Conclusion: This study shows that thrombocytopenia is common in Chinese NSCLC patients receiving gemcitabine-based regimens. Chemotherapy cycles and stage might be the important factors influencing the occurrence of gemcitabine-based regimens-induced thrombocytopenia. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the expressions of circulating angiogenic factors affected by pamidronic acid (PA) intravenous infusion in bone metastatic breast cancer patients and the impact on their prognosis. Methods: Peripheral blood of ten bone metastatic breast cancer patients was collected for serum insulin-like growth factor-1 (IGF-1) and platelet endothelial cell adhesion molecule-1 expression detection just before and 2 days after PA infusion. Results: Both IGF-1 and platelet endothelial cell adhesion molecule-1 concentrations decreased after PA treatment for 48 hours (P<0.05). Modification was defined as >20% decrease recorded 2 days after PA administration. The decrease of IGF-1 was more significant in breast cancer patients who had received previous hormonotherapy. Moreover, the progression-free survival of first-line chemotherapy treatment of IGF-1 modified patients was longer than that of IGF-1 unmodified patients (P=0.009). Conclusion: PA treatment could suppress circulating serum IGF-1 and platelet endothelial cell adhesion molecule-1 concentrations; moreover, the prognosis of patients in IGF-1 unmodified group was relatively poor.

Objective: To investigate the predictors and impact of cytotoxic second-line chemotherapy for stage IIIa-IV nonsmall cell lung cancer (NSCLC) patients in China. Methods: Medical records of 132 patients who underwent chemotherapy from January 2008 to December 2010 in our hospital were retrospectively reviewed. The response of first-line gemcitabine (GEM) and platinum doublets chemotherapy was evaluated, and the overall survival (OS) of all patients was followed. Further, risk factors of receipt cytotoxic second-line chemotherapy or not were identified and evaluated by univariate analyses. Results: Sixty-six cases have undergone cytotoxic second-line chemotherapy for lung cancer. The OS between patients received first-line GEM plus platinum doublets chemotherapy and patients without cytotoxic second chemotherapy had no statistical difference (P = 0.73). Smoking or not might be a meaningful predictor for cytotoxic second-line therapy among these patients in this investigation (P < 0.05). Other factors, such as age (≥65 or < 65), gender, alcohol use, hypertension, diabetes mellitus, histology type, number of cycles of first-line chemotherapy, and response of first-line chemotherapy had no statistical difference between patients received first-line GEM plus platinum doublets chemotherapy and patients received cytotoxic second chemotherapy (P > 0.05). In the sub-analysis, we found that the OS between patients received first-line GEM plus platinum doublets chemotherapy and patients without cytotoxic second chemotherapy had statistical difference in the population whose OS < 540 days (P = 0.019). Moreover, in these patients, the blood type was found to be a selected factor in receiving cytotoxic second-line chemotherapy or not (P < 0.05). Whereas other factors were not shown their selected effect (P > 0.05). Conclusion: This study demonstrated that though the essentiality of cytotoxic second-line chemotherapy for stage IIIa-IV EGFR mutation indefinite NSCLC is unclear, patients who are blood type AB with poor prognosis and short OS might be a dominant population for cytotoxic second-line chemotherapy.
