Objective: To determine the clinical epidemiological characteristics of newly reported human immunodeficiency virus/acquired immunodeficiency syndrome （HIV/AIDS）in southwestern China from 2001 to 2017., Methods: Clinical data of newly diagnosed HIV/AIDS from 2001 to 2017 in the West China Hospital of Sichuan University were reviewed and analyze., Results: A total of 1 520 228 patients were screened for HIV, including 285 983 outpatient and emergency patients and 1 234 245 inpatients. About 4 037 (0.27%) patients were confirmed with HIV/AIDS. The confirmation rate increased from 2001 to 2013, followed by a slight decline from 2014 to 2017. The male to female sex ratio of confirmed HIV/AIDS was 3.49:1 from 2001 to 2017, ranging from 1.65:1 to 5.08:1. The majority of patients were identified as Han (88.23%), had low education (58.66%), and married (54.75%). Peasants/herdsman comprised 26.33% of the patients. The proportion of young (15-29 years old), and middle-aged (≥50 years old) patients and those who were unmarried and had high education (senior high school and above) increased over time. Heterosexual transmission remained stable at about 60% while homosexual transmission increased by about 15% ( χ 2 =14.436, P ＜0.005) since 2008. Transmissions through drug abuse( χ 2 =71.633, P ＜0.005) and blood( χ 2 =16.672, P ＜0.005) decreased. Of the 899 female newly reported HIV/ADIS patients, 77.20% were infected through heterosexual relationship. In comparison, of the 3 138 male patients, 61.41% were infected through heterosexual and 18.10% through homosexual relationships. Homosexual transmissions decreased with age, but heterosexual transmissions increased with age. Mother-to-child transmissions were concentrated in those between 0 and 15 years old (100%)., Conclusion: Newly diagnosed HIV/AIDS cases increased over the years in the West China Hospital of Sichuan University, in particular in those of young and middle-aged, highly educated and unmarried. Heterosexual transmissions remain the main route., (Copyright© by Editorial Board of Journal of Sichuan University (Medical Science Edition).)

The growing number of people over age 50 with HIV requires research, policy, and practice to develop a more comprehensive understanding of the health consequences of HIV in older individuals. We conducted a scoping review of peer-reviewed and grey literature published since 1996 to explore the impacts of aging on the health of older people with HIV (50 years or older). We included 209 studies (two systematic reviews, 174 quantitative studies, 28 qualitative studies, and five mixed methods studies). Health topics addressed include: HIV- and aging-related comorbidities, disease progression, neurocognitive functioning, mental health conditions, psychological well-being, social supports, stigma, antiretroviral adherence, health care utilization/access, and sexual risk behaviour. We recommend that future research takes a broader view of health, looks at aging from a strength-based perspective and examines the issue using diverse perspectives (i.e., geographic location, multiple methods, time of diagnosis, time on antiretroviral therapy (ART), demographic diversity).

Background: Although Mycoplasma genitalium (MG) is a common sexually transmitted infection (STI), very little information regarding the prevalence of MG among MSM (men who have sex with men) is available in China. The objective of this study was to determine the prevalence of MG among MSM in the city of Shenzhen, Guangdong Province, China, and to identify the potential risk factors associated with MG infection in this population., Methods: Between January and May 2010, a total of 409 MSM were recruited in Shenzhen, Guangdong Province, China. An anonymous questionnaire was used to collect information regarding their sociological and sexual behaviors. In addition, their first-void urine (FVU) samples and rectal swabs were collected for PCR-based MG testing., Results: Among the 406 FVU and 405 rectal swab samples were collected from 409 MSM, the overall MG prevalence was 8.1% (33/406, 95% CI 5.7%-10.6%), with a FVU positivity of 3.4% (95% CI 1.7%-5.4%) and a rectal positivity of 5.4% (95% CI 3.5%-7.7%). Using both univariate and multivariable logistic regression analyses, urethral MG infection was significantly associated with having more heterosexual behaviors (AOR 7.16, 95% CI 1.89-27.13), and with having unprotected anal intercourse in the past six months (AOR 4.80, 95% CI 1.40-16.47). Rectal MG infection was significantly associated with HIV infection based on univariate logistic regression analysis (OR = 4.49, 95% CI 1.18-17.12)., Conclusions: In this study, we investigated the prevalence of MG infection in the population of interest, as determined from both urethral and rectal specimen. We showed that MG was more prevalent in MSM who had bisexual behaviors compared to those who engaged only in homosexual behaviors. Further work is needed to establish the mode of MG transmission and to identify its role in HIV transmission. Meanwhile, more attention should be paid to MG infection among MSMs, and especially bisexual MSMs, which might have critical implications for effective HIV/STD control in China.

Detection of people with acute HIV infection (AHI) affords an important opportunity for early HIV treatment and prevention. HIV RNA reverse transcriptase-polymerase chain reaction (RT-PCR) testing with two-stage pooling scheme was used to detect the AHI in specimens collected from sexually transmitted disease (STD) clinic patients in Guangxi, China. A total of 246 HIV RNA tests were required to screen 11 395 samples negative for conventional enzyme immunoassay (EIA) and Western blot assays, and five AHI cases (0.04%, 95%CI 0.02% to 0.10%) with a high viral load (median of 265,677 copies per ml) were detected. The total expenditure for RT-PCR testing reflected an added cost of $2.9 per specimen screened and $6575 per additional case of AHI identified among the study population. This study supports the feasibility of pooled RNA testing in addition to detection of HIV infections among patients at STD clinics in China, but the cost effectiveness should be carefully considered.
