The level of evidence for HIV transmission risk through condomless sex in serodifferent gay couples with the HIV-positive partner taking virally suppressive antiretroviral therapy (ART) is limited ...compared with the evidence available for transmission risk in heterosexual couples. The aim of the second phase of the PARTNER study (PARTNER2) was to provide precise estimates of transmission risk in gay serodifferent partnerships.
The PARTNER study was a prospective observational study done at 75 sites in 14 European countries. The first phase of the study (PARTNER1; Sept 15, 2010, to May 31, 2014) recruited and followed up both heterosexual and gay serodifferent couples (HIV-positive partner taking suppressive ART) who reported condomless sex, whereas the PARTNER2 extension (to April 30, 2018) recruited and followed up gay couples only. At study visits, data collection included sexual behaviour questionnaires, HIV testing (HIV-negative partner), and HIV-1 viral load testing (HIV-positive partner). If a seroconversion occurred in the HIV-negative partner, anonymised phylogenetic analysis was done to compare HIV-1 pol and env sequences in both partners to identify linked transmissions. Couple-years of follow-up were eligible for inclusion if condomless sex was reported, use of pre-exposure prophylaxis or post-exposure prophylaxis was not reported by the HIV-negative partner, and the HIV-positive partner was virally suppressed (plasma HIV-1 RNA <200 copies per mL) at the most recent visit (within the past year). Incidence rate of HIV transmission was calculated as the number of phylogenetically linked HIV infections that occurred during eligible couple-years of follow-up divided by eligible couple-years of follow-up. Two-sided 95% CIs for the incidence rate of transmission were calculated using exact Poisson methods.
Between Sept 15, 2010, and July 31, 2017, 972 gay couples were enrolled, of which 782 provided 1593 eligible couple-years of follow-up with a median follow-up of 2·0 years (IQR 1·1–3·5). At baseline, median age for HIV-positive partners was 40 years (IQR 33–46) and couples reported condomless sex for a median of 1·0 years (IQR 0·4–2·9). During eligible couple-years of follow-up, couples reported condomless anal sex a total of 76 088 times. 288 (37%) of 777 HIV-negative men reported condomless sex with other partners. 15 new HIV infections occurred during eligible couple-years of follow-up, but none were phylogenetically linked within-couple transmissions, resulting in an HIV transmission rate of zero (upper 95% CI 0·23 per 100 couple-years of follow-up).
Our results provide a similar level of evidence on viral suppression and HIV transmission risk for gay men to that previously generated for heterosexual couples and suggest that the risk of HIV transmission in gay couples through condomless sex when HIV viral load is suppressed is effectively zero. Our findings support the message of the U=U (undetectable equals untransmittable) campaign, and the benefits of early testing and treatment for HIV.

IntroductionKnowing the factors associated with HIV transmission is necessary in order to design preventive programmes tailored to the epidemiological situation in each region and population.AimOur ...objective was to study the sociodemographic, clinical and behavioural characteristics of men who have sex with men (MSM) who were newly diagnosed with HIV infection.MethodsWe carried out an observational, descriptive, study on all MSM newly diagnosed with HIV infection in one clinic for sexually transmitted infections (STI) and HIV clinic in Madrid between 2014 and 2019. Information on sociodemographic, clinical, and behavioural characteristics of participants per year of diagnosis was collected.ResultsWe detected a total of 1,398 people with HIV infection, 253 of whom were recent seroconverters (rSCV) with a median duration of documented seroconversion of 6 months. From the total, 97.9% infections were sexually transmitted and 2.1% involved injected drugs, i.e. slam practices. The average age was 32.9 years (range: 15.6-74.9), 51.8% were Spanish and 40% Latin American. These diagnoses decreased in Spanish people and increased in Latin Americans during the study period. Of the rSCV, 73.9% had condomless sex under the influence of drugs and 28.9% participated in chemsex sessions. Apps were used by 92.6% rSCV for sexual encounters and 70.4% of them attributed HIV transmission to their use.ConclusionsCombination of HIV prevention strategies, as pre-exposure prophylaxis, should be reinforced among young MSM, especially those born in Latin America, those who use drugs for sex, and those who use apps in search of sexual contacts.
Objective. Premature atherosclerosis in patients with SLE is partially explained by traditional risk factors; therefore, we aimed to identify lupus-related risk factors for coronary artery ...calcifications.
Methods. An inception cohort of 139 lupus patients (93% females) was screened for coronary artery calcifications using Multidetector CT, after 5.1 years of follow-up. Clinical and immunological variables and cardiovascular risk factors were assessed longitudinally. Also, 100 age- and sex-matched healthy subjects were studied. Correlates for calcifications were analysed in lupus patients, including levels of lipids and inflammatory molecules in samples obtained at enrolment, mid-term follow-up and at screening.
Results. At enrolment, lupus patients were 27.2 (9.1) years of age and with a disease duration of 5.4 (3.8) months. Calcifications were detected in 7.2% of patients and 1% of controls unadjusted odds ratio (OR) 7.7, 95% CI 1.05, 336.3, P = 0.02. In lupus, calcifications were detected since the age of 23 years and from 3 years of diagnosis. Patients with calcifications were older, post-menopausal, and had higher levels of serum apolipoprotein B and Framingham risk scores (P < 0.05). Lupus-related factors identified included age at diagnosis, IgG aCLs, cumulative lupus activity, length of moderate/severe activity and cumulative dose of prednisone and CYC (P < 0.05). Use of anti-malarials was protective (P = 0.006). Logistic regression analysis showed as predictors of calcification: disease duration (OR 15.1, 95% CI 2.6, 87.2), age at enrolment (OR 8.5, 95% CI 1.7, 43.0) and SLEDAI 2000 update (SLEDAI-2K) mean area under the curve (OR 12.3, 95% CI 2.5, 61.8). Longitudinal analyses of lipids and inflammatory molecules did not differ between patients.
Conclusions. Disease activity is a potentially modifiable risk factor for coronary artery calcifications in SLE. Therefore, management of traditional risk factors plus tight control of lupus activity, including the use of anti-malarials, is recommended.
The aim of this study was to estimate the age at natural menopause in women with SLE.
One thousand and thirty-nine consecutive SLE patients <60 years of age were surveyed. Demographic and clinical ...data were queried by a single investigator. SLE characteristics and co-morbidities were retrieved from their medical records. Natural menopause was defined as amenorrhoea ≥12 months in the absence of previous hysterectomy, CYC exposure and severe chronic kidney disease (SCKD). Pregnant women and those with menses during the 12 months prior to interview were considered premenopausal. Median age at menopause was estimated by both logit and survival analyses. In addition, mean age at menopause was calculated for patients aged ≥40 years. Factors associated with age at natural menopause were assessed by Cox regression analysis.
A total of 961 SLE women were analysed. At interview, most patients (81.6%) were premenopausal, 7.9% had natural menopause, 6.3% were postmenopausal previously exposed to CYC, 4.1% had undergone hysterectomy before menopause and 0.1% presented with SCKD and amenorrhoea. The mean age at interview was 35.2 years (s.d. 10.1), the mean age at SLE diagnosis was 26.9 years (s.d. 8.6) and the mean duration of disease was 8.2 years (s.d. 7.1). The mean recalled age at menopause was 46.4 years (s.d. 4.7). Median age at menopause estimated by logit and survival analyses were 50.7 and 50.8 years, respectively. Only the age at SLE diagnosis was associated with age at natural menopause.
Median age at natural menopause in women with lupus is 50 years. This is consistent with the age at menopause reported in the general population.

To estimate life expectancy of people with HIV (PWH) and describe causes of death.
Antiretroviral therapy (ART)-naive adults from the CoRIS cohort starting ART in 2004-2019.
We calculated life ...expectancy at age 40 for men and women according to their ART initiation period, and stratified by transmission category, CD4 + cell count and AIDS diagnosis. We estimated life expectancy in 10-year age bands using life tables constructed from mortality rates, estimated through Poisson models.
Life expectancy increased from 65.8 95% confidence interval (CI) 65.0-66.6 in 2004-2008 to 72.9 (72.2-73.7) in 2014-2019 in men general population comparators (GPC): 79.1 and 81.2 years, respectively and from 65.8 (65.0-66.6) to 72.5 (71.8-73.3) in women (GPC: 84.9 and 86.4, respectively). Non-AIDS-related deaths accounted for 68% of deaths among men and 78% among women. Life expectancy was longer when starting ART with higher CD4 + cell counts and without AIDS. For men acquiring HIV through sex with men, starting ART in 2014-2019 without AIDS, life expectancy was 75.0 (74.2-75.7) with CD4 + cell count less than 200 cells/μl, rising to 78.1 (77.5-78.8) with CD4 + cell count at least 350 cells/μl. Corresponding figures were 70.1 (69.4-70.9) and 76.0 (75.3-76.7) for men acquiring HIV heterosexually (HTX) and 61.5 (60.7-62.3) and 69.0 (68.2-69.8) for those acquiring HIV through injection drug use (IDU). For women starting ART from 2014 without AIDS, life expectancy increased from 71.7 (71.0-72.4) to 77.3 (76.7-77.9) among HTX and from 63.7 (62.9-64.5) to 70.7 (70.0-71.5) among IDU.
Our findings confirm the progressive improvement of life expectancy in PWH in Spain over the last decades, supporting the insurability of PWH on suppressive ART in our current setting and time.

Scarce information is available on the resources to deal with the Sexually Transmitted Infections (STIs), both in the clinic and in the laboratory. The objective is to describe and know the reality ...of the clinics and laboratories that treat these infections in Spain.
Cross-sectional observational study with data collection through a survey aimed at the members of the GEITS Group.
Responses were obtained from 24 centers (response rate 38.1%) belonging to 10Autonomous Communities. Regarding STI consultations, 38% require that the patient present a health card to provide assistance, and 31.8% only provide it by referral from another doctor. The 52.4% perform diagnostic methods in the care center. Regarding laboratories, 18.2% do not offer immediate response diagnostic tests, although 100% have PCR against Neisseria gonorrhoeae and Chlamydia trachomatis, 47.8% against Mycoplasma genitalium and 65% detect lymphogranuloma venereum genotypes. All laboratories continue to perform culture and gonococcal sensitivity techniques, and 20% perform molecular methods for detection of MG antimicrobial resistance.
There is great variability in the provision of human and material resources both in the clinics and in the laboratories that attend STIs. In a significant number of centers there are limitations for patient access. Although laboratories have molecular biology technologies, not all of them offer immediate response tests. All laboratories detect N.gonorrhoeae infection by PCR and also by culture, which allows sensitivity testing in all centers.
