    BACKGROUND: Men-who-have-sex-with-men (MSM) are at high risk of HIV and sexually transmitted infection (STI) transmission. Asymptomatic STIs are common in MSM and remain undiagnosed and untreated where syndromic management is advocated. Untreated STIs could be contributing to high HIV rates. This study investigated symptomatic (SSTI) and asymptomatic STIs (ASTIs) in MSM in Cape Town. METHODS: MSM, 18 years and above, were enrolled into this study. Participants underwent clinical and microbiological screening for STIs. Urine, oro-pharyngeal and anal swab specimens were collected for STI analysis, and blood for HIV and syphilis screening. A psychosocial and sexual questionnaire was completed. STI specimens were analysed for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) infection. RESULTS: 200 MSM were recruited with a median age of 32 years (IQR 26-39.5). Their median number of sex partners within the last year was 5 (IQR 2-20). 155/200 (78%) reported only male sex partners while 45/200 (23%) reported sex with men and women. 77/200 (39%) reported transactional sex. At enrolment, 88/200 (44%) were HIV positive and 8/112 (7%) initially HIV-negative participants seroconverted during the study. Overall, 47/200 (24%) screened positive for either NG or CT. There were 32 MSM (16%) infected with NG and 7 (3.5%) of these men had NG infections at two anatomical sites (39 NG positive results in total). Likewise, there were 23 MSM (12%) infected with CT and all these men had infections at only one site. Eight of the 47 men (17%) were infected with both NG and CT. ASTI was more common than SSTI irrespective of anatomical site, 38 /200 (19%) versus 9/200 (5%) respectively (p<0.001). The anus was most commonly affected, followed by the oro-pharynx and then urethra. Asymptomatic infection was associated with transgender identity (OR 4.09 CI 1.60-5.62), ≥5 male sex partners in the last year (OR 2.50 CI 1.16-5.62) and transactional sex (OR 2.33 CI 1.13-4.79) but not with HIV infection. CONCLUSIONS: Asymptomatic STI was common and would not have been detected using a syndromic management approach. Although molecular screening for NG/CT is costly, in our study only four MSM needed to be screened to detect one case. This supports dual NG/CT molecular screening for MSM, which, in the case of confirmed NG infections, may trigger further culture-based investigations to determine gonococcal antimicrobial susceptibility in the current era of multi-drug resistant gonorrhoea.

    Missed opportunities for NCD multimorbidity prevention in adolescents and youth living with HIV in urban South Africa
    (2020-06-01) Kamkuemah, Monika; Gausi, Blessings; Oni, Tolu
    Abstract Background Epidemiological transition in high HIV-burden settings is resulting in a rise in HIV/NCD multimorbidity. The majority of NCD risk behaviours start during adolescence, making this an important target group for NCD prevention and multimorbidity prevention in adolescents with a chronic condition such as HIV. However, there is data paucity on NCD risk and prevention in adolescents with HIV in high HIV-burden settings. The aim of this study was to investigate the extent to which NCD comorbidity (prevention, diagnosis, and management) is incorporated within existing adolescent HIV primary healthcare services in Cape Town, South Africa. Methods We reviewed medical records of 491 adolescents and youth living with HIV (AYLHIV) aged 10–24 years across nine primary care facilities in Cape Town from November 2018–March 2019. Folders were systematically sampled from a master list of all AYLHIV per facility and information on HIV management and care, NCDs, NCD risk and NCD-related health promotion extracted. Results The median age was 20 years (IQR: 14–23); median age at ART initiation 18 years (IQR: 6–21) and median duration on ART 3 years (IQR: 1.1–8.9). Fifty five percent of participants had a documented comorbidity, of which 11% had an NCD diagnosis with chronic respiratory diseases (60%) and mental disorders (37%) most common. Of those with documented anthropometrics (62%), 48% were overweight or obese. Fifty nine percent of participants had a documented blood pressure, of which 27% were abnormal. Twenty-six percent had a documented health promoting intervention, 42% of which were NCD-related; ranging from alcohol or substance abuse (13%); smoking (9%); healthy weight or diet (9%) and mental health counselling (10%). Conclusions Our study demonstrates limited NCD screening and health promotion in AYLHIV accessing healthcare services. Where documented, our data demonstrates existing NCD comorbidity and NCD risk factors highlighting a missed opportunity for multimorbidity prevention through NCD screening and health promotion. Addressing this missed opportunity requires an integrated health system and intersectoral action on upstream NCD determinants to turn the tide on the rising NCD and multimorbidity epidemic.

    Prevalence and incidence of renal dysfunction in patients initiating Antiretroviral Therapy at a Primary Health Care Centre in Gugulethu, Cape Town : a cohort study
    (2013) Kamkuemah, Monika; Myer, Landon; Little, Francesca
    Tenofovir disoproxil fumarate (TDF) is used worldwide for the treatment of HIV-1 infection. Tenofovir has been found to be associated with declines in renal function and chronic kidney disease in HIV-infected patients. There are limited data on how soon after antiretroviral therapy (ART) initiation any loss of renal function can be detected. We studied a cohort of HIV-infected adults initiating TDF-containing ART regimens at the Hannan Crusaid Antiretroviral Treatment Centre in Gugulethu. The centre provides ART to the residents of the Gugulethu and Nyanga districts situated on the outskirts of Cape Town. We described the prevalence and incidence of renal dysfunction in this cohort, the patterns of change in their renal function in the first 12 months on therapy and factors associated with renal dysfunction. We also examined the diagnostic value of early serum creatinine tests in identifying incident renal dysfunction after 12 months.
