SUMMARYThis study describes the incidence rate of reported lymphogranuloma venereum (LGV) in men who have sex with men (MSM) in Barcelona from 2007 to 2012. Epidemiological, clinical and sexual behaviour characteristics of LGV cases are described. Seroadaptive behaviours as a transmission risk factor were assessed by a telephone questionnaire during 2012. Data were handled on a strictly confidential basis. LGV annual rate ratios in MSM were compared with cases from 2007. Differences were statistically analysed with a Poisson test. The incidence rate of LGV in MSM aged 15–69 years ranged from 32·1/105MSM per year in 2007 to 182·7/105MSM per year in 2012. In 2012, 31/51 LGV cases (61%) answered the telephone questionnaire, of which 84% (26/31) were HIV positive, 39% (12/31) reported having sex according to their partners’ serostatus and 7% (2/31) used strategic positioning. The incidence of LGV has increased since 2007 and mainly affects HIV-positive MSM. It is probable that seroadaptation has facilitated LGV transmission.

ObjectivesLymphogranuloma venereum (LGV) is an STI caused by Chlamydia trachomatis serovars L1-L3. In Europe, the current epidemic is caused mainly by L2b genovariant, although increasing cases associated with other L2 variants have been reported. Here, we assessed the distribution of rectal LGV genovariants among men having sex with men (MSM) in Italy.MethodsFrom 2016 to 2020, all the anorectal swabs collected from MSM attending the STI Clinic of St. Orsola-Malpighi Hospital in Bologna and positive for C. trachomatis were stored. LGV infection was confirmed by a pmpH PCR, and, subsequently, a fragment of the ompA gene was amplified and sequenced. Sequences were aligned to reference strains representing different LGV variants.ResultsLGV cases accounted for one-third of all chlamydial rectal infections with a total prevalence of 4.1% (76/1852). Total number of LGV cases per year remained constant. LGV was mainly found in symptomatic patients (>65%), older than 30 years, with a high burden of other STIs (63.7% HIV-positive, 35.5% with concurrent rectal gonorrhoea, 19.7% with early syphilis). A decreasing trend in HIV-LGV co-infection was noticed over time. Three main LGV genovariants were detected (L2f, 46.1%; L2b, 23.0%; L2-L2b/D-Da, 16.9%), together with other known L2b variants (mainly L2bV2 and L2bV4). Two novel L2b ompA variants with non-synonymous single-nucleotide polymorphisms were found. Over time, the percentage of L2f cases dropped gradually, with a significant increase in L2-L2b/D-Da cases (p=0.04).ConclusionsIn our area, LGV is endemic among MSM with different circulating genovariants. Active surveillance and genotyping programmes are needed to reduce re-establishing of LGV infection.

Background: HIV infection is prevalent among men who have sex with men (MSM), and sexual roles may be important factors related to it. This study aims to describe the sexual roles, risky sexual behaviors and HIV prevalence among MSM, and to determine associated factors for HIV prevalence. Methods: A convenient sampling method was used to recruit participants in a non-government organization in Changsha, China. The participants were asked to complete a 38-item self-administered questionnaire regarding demographic characteristics and risky sexual behaviours before collecting blood samples for HIV testing. Chi-square tests and logistic regression analysis were conducted with the Statistical Package for the Social Sciences Version 18.0 and other indexes were statistically described. Results: A total of 601 MSMs who came to a local non-government organization for voluntary counseling and testing completed a pencil-and-paper survey and were tested for HIV. The overall HIV prevalence of this sample was 13.3%, and that of the bottoms (16.3%) was similar to the versatiles (15.9%) but higher than the tops (6.1%). Bivariate analyses showed that there were significant differences in age, marital status, monthly income, sexual orientation, age at first sex, sex of the first sex partner, sex with a woman in the last 6 months, oral sex with a man in the last 6 months and role of oral sex among 3 subgroups of MSM (p < 0.05). Multivariate analyses indicated that MSMs who played the role of either the bottoms or the versatiles were more likely to be HIV positive than the tops. While MSMs who used condoms in anal sex in the last 6 months, had sex with a woman in the last 6 months or had oral sex with a man in the last 6 months were less likely to be HIV positive. Conclusion: Different sexual roles are associated with high-risk sexual behaviors among MSMs and their HIV infection status. Further research should target preventive interventions, and improve the effectiveness of the intervention according to the characteristics of the subgroups to reduce the HIV transmission among Chinese MSM.

Background: Transnational marriages are common as a result of globalization, and immigrant mothers face various degrees of differences in language and culture backgrounds. Mothers have great influences on the development of their children, but the effects of immigrant mothers' language and culture backgrounds on developmental delays (DD) are seldom studied. To evaluate the potential effects of immigrant mothers' language and culture backgrounds on DD of their children, we conducted a nationwide study in Taiwan.Methods: We analyzed the data from the national registry of DD in Taiwan from 2010 to 2013 and compared the incidence of DD in young children born to mothers from China, Vietnam, and Indonesia, where most of the immigrant mothers in Taiwan come from. Amongst the three countries, China is the closest to Taiwan in terms of language and culture, followed by Vietnam, and then Indonesia.Results: We identified 4,604 patients of DD in children under 7 years old. The incidence rates showed an increasing trend among children born to mothers from China, Vietnam, and Indonesia (p &lt; 0.01 in all years). Using children born to mothers from Vietnam, whose incidence rate of DD was in the middle amongst the three groups, as the reference, we found the incidence rate ratios in children born to mothers from China ranged from 0.65 to 0.73, and those in children born to mothers from Indonesia ranged from 1.04 to 1.26.Conclusions: The findings support the important role of mothers' language and culture backgrounds in the development of children.

Previous studies have examined the distinct stigmas of people living with HIV or of men who have sex with men (MSM). To capture the composite stress of HIV-positive MSM and the mixed stigma they experience, we conceptualized a compound stigma combining HIV status and homosexual identity. At two waves with an interval of 6 months, the results of 112 Chinese newly diagnosed HIV-positive MSM showed that dual stigma at baseline increased distress symptoms 6 months later. Resilience moderated these effects, as the dual stigma increased, distress symptoms intensified more rapidly for individuals with lower resilience than they did for those with higher resilience. Our findings highlight that dual stigma, as an intensified risk factor, predicted distress among the Chinese newly diagnosed HIV-positive MSM, conditioned by the protective factor of resilience. The results have strong implications for developing resilience-based intervention programs in this population.
