' if U equals U what does the second U mean?': sexual minority men's accounts of HIV undetectability and untransmittable scepticism.

The everyday meaning and use of HIV 'undetectability' raises significant questions about the social and sexual significance of this state of viral suppression. We conducted in-depth, semi-structured interviews with 25 sexual minority men living in Vancouver, Canada, including men living with HIV. Interviews were audio-recorded, transcribed verbatim and analysed using grounded theory. Most participants understood being undetectable to signify that someone living with HIV is at a 'low,' 'lower,' or 'slim to no' risk of sexually transmitting HIV, as opposed to meaning 'uninfectious' or 'untransmittable'. Men discussed how undetectability was communicated in-person and online, including via sexual networking apps, and revealed how it is sometimes confused or conflated with another biomedical advance in HIV-prevention, namely pre-exposure prophylaxis (PrEP). HIV-negative men expressed significant scientific scepticism, a reluctance to incorporate a partner's low viral load or undetectable HIV status into their sexual decision-making, and an enduring fear associated with knowingly having sex with someone who is HIV-positive. We describe this as a form of untransmittable scepticism. While international campaigns have worked to communicate the scientific message that 'undetectable equals untransmittable' (U = U), the sexual stigma attached to HIV remains durable among some gay, bisexual, queer and other men who have sex with men.

Pregabalin-induced urticarial rash and neutropenia in a renal transplant recipient: a case report.

BACKGROUND: Pregabalin is a medication used to treat epilepsy, neuropathic pain and generalised anxiety disorder. The most common side effects of pregabalin include dizziness, drowsiness, weight gain, ataxia and diplopia. On the other hand, neutropenia and rash are rare side effects of pregabalin, and at the time of writing, there are only two documented cases of neutropenia and one of rash in the literature, none of which involved renal transplant recipients. CASE PRESENTATION: We present a 37-year-old renal transplant recipient who was admitted with lethargy, sore throat, urticarial rash and neutropenia after recently being commenced on pregabalin. On physical examination, he had erythematous urticarial rash near his renal transplant scar, on his right elbow, left knee and left wrist. Bacterial/viral serology and immunology were all negative. A blood film confirmed neutropenia and revealed reactive lymphocytes and neutrophil left shift, and those features were compatible with drug reaction. After cessation of the pregabalin, the neutropenia resolved. No other causes of neutropenia or urticarial rash were identified. CONCLUSION: To the best of our knowledge, we have described the first case of concomitant pregabalin-induced neutropenia and urticarial rash in a kidney transplant patient. This case report highlights the importance of close monitoring when starting any new medications, particularly in the immunosuppressed population, and is relevant because of the growing usage of pregabalin for treating neuropathic pain in such patients and the risk that a missed pregabalin-related neutropenia could lead to unnecessary modifications of the immunosuppressive treatment.

" it's almost therapeutic, right? Because it's almost like that session that I never had": gay men's accounts of being a participant in HIV research.

Limited research has explored how gay, bisexual and other men who have sex with men describe the impact of their involvement in HIV and sexual health research. We enrolled 166 gay and bisexual men who tested HIV-negative at a community sexual health clinic in Vancouver, British Columbia, into a year-long mixed methods study. Thirty-three of these participants who reported recent condomless anal intercourse were purposively recruited into an embedded qualitative study. Analysis revealed rich accounts of the self-described, interrelated impacts of study participation: (1) pride in contribution and community involvement (e.g., as a rationale for enrolment and an outcome of participation); (2) how one thinks about sexual behaviours and partnerships (e.g., encouraging reflection on the types and amount of sex they have had; in some cases the methods of quantitative data collection were said to have produced feelings of guilt or shame); and (3) experiencing research as a form of counselling (e.g., qualitative interviews were experienced as having a major therapeutic component to them). Our analysis underscores the importance of researchers being reflexive regarding how study participation in HIV research may impact participants, including unintended emotional and behavioural impacts.

Phenindione interference in enzymatic creatinine assay - A case report.

Enzymatic creatinine assays are considered superior to Jaffe assays due to greater analytical specificity. We report a case of phenindione interference with an enzymatic assay resulting in significant misclassification in a patient with chronic kidney disease (CKD). Analysis of creatinine values of a further 36 patients who were treated with phenindione showed significant negative interference of phenindione with the Roche enzymatic creatinine assay.

HIV-negative gay men's accounts of using context-dependent sero-adaptive strategies.

We enrolled 166 gay and bisexual men who tested HIV-negative at a community sexual health clinic in Vancouver, British Columbia, into a year-long mixed-methods study. A subsample of participants who reported recent condomless anal sex (n = 33) were purposively recruited into an embedded qualitative study and completed two in-depth qualitative interviews. Analysis of baseline interviews elicited three narratives relevant to men's use of context- or relationally-dependent HIV-risk management strategies: (1) seroadaptive behaviours such as partner testing and negotiated safety agreements used with primary sexual partners, (2) serosorting and seroguessing when having sex with new partners and first-time hookups and (3) seroadaptive behaviours, including one or more of seropositioning/strategic positioning, condom serosorting and viral load sorting, used by participants who knowingly had sex with a serodiscordant partner. Within men's talk about sex, we found complex and frequently biomedically-informed rationale for seroadaptation in men's decisions to have what they understood to be various forms of safe or protected condomless anal sex. Our findings support the need for gay men's research and health promotion to meaningfully account for the multiple rationalities and seroadaptive strategies used for having condomless sex in order to be relevant to gay men's everyday sexual decision-making.

Knowledge and attitudes of syphilis and syphilis pre-exposure prophylaxis (PrEP) among men who have sex with men in Vancouver, Canada: a qualitative study.

OBJECTIVES: In British Columbia, Canada, syphilis is at record-high rates, with over 80% of cases in 2017 seen in gay, bisexual and other men who have sex with men (GBM). The syphilis epidemic is of particular concern for those living with HIV, since syphilis may lead to more serious complications in this population. We sought to explore syphilis-related knowledge and attitudes around biomedical prevention options for syphilis, with the goal of informing effective strategies to prevent syphilis. DESIGN: We conducted a qualitative study consisting of in-depth, individual interviews from December 2016 to June 2017. Our interviews focused on participants' knowledge about syphilis and perceptions regarding syphilis pre-exposure prophylaxis (PrEP). Interviews were analysed using Grounded Theory. PARTICIPANTS: Twenty-five GBM were interviewed (64% white; median age: 43 years), including men living with HIV and/or with a history of syphilis. SETTING: Vancouver, British Columbia. RESULTS: Five interrelated themes emerged. First, GBM were aware of the local syphilis epidemic. Second, syphilis-related knowledge differed according to syphilis and HIV serostatus. Third, competing ideas emerged regarding men's concerns about syphilis. While our participants expressed concern about getting syphilis, they also described the importance of sexual pleasure. Fourth, many participants said that syphilis was not perceived to be alarming; preventing HIV infection remained a primary concern for many. Finally, while syphilis PrEP was appealing to those living with HIV or a prior syphilis diagnosis, others were concerned about antibiotic resistance, cost and side effects. CONCLUSIONS: Our participants organised their safer sex strategies around HIV, not syphilis. Although syphilis-related knowledge was relatively high among GBM living with HIV and those with a prior syphilis diagnosis, this knowledge did not appear to be related with safer sexual practices, such as increased condom use. This work highlights the importance of examining other potential prevention solutions, such as syphilis PrEP.
