The prevalence of sarcopenia is high in patients with CD requiring bowel resection. It significantly increases the risk of major postoperative complications and has clinical implications with respect to nutrition management before surgery for CD.

Background Lipid abnormalities are prevalent among people living with human immunodeficiency virus (HIV) (PLWH) and contribute to increasing risk of cardiovascular events. This study aims to investigate the incidence of dyslipidemia and its risk factors in PLWH after receiving different first-line free antiretroviral regimens. Methods PLWH who sought care at the Third People's Hospital of Shenzhen from January 2014 to December 2018 were included, and the baseline characteristics and clinical data during the follow-up were collected, including total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). The risk factors of dyslipidemia after antiretroviral therapy were analyzed with the generalized estimating equation model. Results Among the 7623 PLWH included, the mean levels of TC, HDL-C and LDL-C were 4.23 ± 0.85 mmol/L, 1.27 ± 0.29 mmol/L and 2.54 ± 0.65 mmol/L, respectively, and the median TG was 1.17 (IQR: 0.85−1.68) mmol/L. Compared with that in PLWH receiving tenofovir disoproxil fumarate (TDF) + lamivudine (3TC) + ritonavir-boosted lopinavir (LPV/r), zidovudine (AZT) + 3TC + efavirenz (EFV), and AZT + 3TC + LPV/r, the incidence of dyslipidemia was lower in PLWH receiving TDF + 3TC + EFV. In multivariate analysis, we found that the risks of elevations of TG, TC, and LDL-C were higher with TDF + 3TC + LPV/r (TG: odds ratio [OR] = 2.82, 95% confidence interval [CI]: 2.55−3.11, P < 0.001; TC: OR = 1.24, 95% CI: 1.14−1.35, P < 0.001; LDL: OR = 1.06, 95% CI: 1.00−1.12, P = 0.041), AZT + 3TC + EFV (TG: OR = 1.41, 95% CI: 1.28−1.55, P < 0.001; TC: OR = 1.43, 95% CI: 1.31−1.56, P < 0.001; LDL: OR = 1.18, 95% CI: 1.12−1.25, P < 0.001), and AZT + 3TC + LPV/r (TG: OR = 3.08, 95% CI: 2.65−3.59, P < 0.001; TC: OR = 2.40, 95% CI: 1.96−2.94, P < 0.001; LDL: OR = 1.52, 95% CI: 1.37−1.69, P < 0.001) than with TDF + 3TC + EFV, while treatment with TDF + 3TC + LPV/r was less likely to restore HDL-C levels compared with TDF + 3TC + EFV (OR = 0.95, 95% CI: 0.92−0.97, P < 0.001). In addition to antiretroviral regimens, antiretroviral therapy duration, older age, overweight, obesity and other traditional factors were also important risk factors for dyslipidemia. Conclusion The incidence of dyslipidemia varies with different antiretroviral regimens, with TDF + 3TC + EFV having lower risk for dyslipidemia than the other first-line free antiretroviral regimens in China.

Background:We aimed to examine the evolution of blood lipids and compare the risk of dyslipidemia between antiretroviral-naive people living with HIV who received tenofovir disoproxil fumarate (TDF), lamivudine (3TC), and efavirenz (EFV) (TDF + 3TC + EFV) and those who received coformulated elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide (E/C/F/TAF).Methods:We retrospectively reviewed the medical records of 2343 antiretroviral-naive people living with HIV who initiated TDF + 3TC + EFV or E/C/F/TAF. A propensity score matching method was used to compare longitudinal changes of blood lipids between the 2 groups.Results:By using 1:3 matching ratio, we included 253 and 91 matched patients in TDF + 3TC + EFV group and E/C/F/TAF group, respectively. The levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol were higher in E/C/F/TAF group than those in TDF + 3TC + EFV group at 3, 6, 9, and 12 months (Wilcoxon test, all Ps < 0.05), except for high-density lipoprotein cholesterol at 9 and 12 months. The cumulative rates of hypercholesterolemia, hypertriglyceridemia, and high LDL-C in PLWH with normal lipid levels in E/C/F/TAF group were higher than those in TDF + 3TC + EFV group (hypercholesterolemia, 59.7% vs 21.5%, P < 0.001; hypertriglyceridemia, 69.5% vs 46.3%, P < 00.001; and high LDL-C, 41.5% vs 14.2%, P < 0.001). Multivariate analysis showed treatment with E/C/F/TAF was associated with a significantly higher risk of hypercholesterolemia [adjusted hazard ratio (HR), 4.12; 95% confidence interval (CI): 2.65 to 6.41], hypertriglyceridemia (adjusted HR, 1.69; 95% CI: 1.18 to 2.43), and high LDL-C (adjusted HR, 4.60; 95% CI: 2.66 to 7.97).Conclusions:We concluded that treatment with E/C/F/TAF resulted in higher risks of dyslipidemia compared with TDF + 3TC + EFV.

Background: Understanding the characteristics of newly diagnosed primary human deficiency virus-1 (HIV-1) infection in the context of the post-antiretroviral therapy era and HIV drug prophylaxis is essential for achieving the new target of 95-95-95-95 by 2025. This study reported the characteristics of newly diagnosed primary HIV-1 infection in Shenzhen. Methods: This is a real-world retrospective study. Eighty-seven newly diagnosed primary HIV-1-infected patients were recruited from January 2021 to March 2022 at the Third People's Hospital of Shenzhen. Demographic, epidemiological, diagnostic, drug resistance, and medical data were described and analyzed. Results: Overall, 96.6% (84/87) of the newly identified primary HIV-1-infected patients were male, including 88.5% (77/87) men have sex with men (MSM), with a median age of 29.0 years (Q 1 –Q 3 : 24.0–34.0 years); of these, 85.1% (74/87) reported high-risk sexual behaviors with casual partners. The rate of condom usage was only 28.7% (25/87). The overall rate of pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) was 8.0% (7/87, including 4 PrEP and 3 PEP cases) around the potential exposure, although 41.4% of the patients had prior awareness of such interventions. Moreover, only 19.5% (17/87) had previously used PrEP or PEP. Of those, 58.8% (10/17) of the patients obtained drugs from the internet, and only 35.3% (6/17) reported good compliance. A total of 54.0% (47/87) of subjects were diagnosed by the HIV nucleic acid test. Acute retroviral syndrome appeared in 54.0% (47/87) of patients. The prevalence of transmitted drug resistance (TDR) mutation was 33.9% (19/56), including 6 (10.7%) against nucleoside reverse transcriptase inhibitor (NRTI) plus non-nucleoside reverse transcriptase inhibitor (NNRTI), 8 (14.3%) against NNRTI, and 5 (8.9%) against protease inhibitor (PI) only. Conclusions: Owing to the low utilization rate and incorrect usage of PrEP and PEP, massive efforts are needed to promote HIV-preventive strategies in the MSM population. The extremely high prevalence of TDR mutation in this population implies the need for future pretreatment drug resistance surveillance.
