Multicentre service evaluation of injectable cabotegravir and rilpivirine delivery and outcomes across 12 UK clinics (SHARE LAI-net).

INTRODUCTION: Long-acting injectable cabotegravir + rilpivirine (CAB + RPV LAI) was approved for use in virally suppressed adults in the England and Wales national health service in November 2021. We describe a service evaluation of delivery processes and outcomes in 12 clinics. METHODS: Centres populated a database using information from local policies and clinical records. Services were asked to describe approval processes, clinic pathways, and adherence to national guidelines. Additional data were collected on reasons for regimen choice, treatment discontinuations, and management of viraemia. RESULTS: In total, 518 adults from 12 clinics were approved for CAB + RPV LAI between February 2022 and December 2023. Of the 518 people approved for CAB + RPV LAI, 423 received at least one injection. Median duration on CAB + RPV was 7.5 months (interquartile range 3.7-11.3). In total, 97% of injections were administered within the ±7-day window. Virological failure occurred in 0.7%, and 6% discontinued CAB + RPV. CONCLUSION: In this large UK-based cohort, robust approval processes and clinic protocols facilitated on-time injections and low rates of both discontinuation and virological failure.

Are all blood-based postal sampling kits the same? A comparative service evaluation of the performance of dried blood spot and mini tube sample collection systems for postal HIV and syphilis testing.

OBJECTIVES: We comparatively evaluated two HIV and syphilis blood sampling kits (dried blood spot (DBS) and mini tube (MT)) as part of an online STI postal sampling service that included tests for chlamydia and gonorrhoea. We aimed to see how the blood collection systems compared regarding sample return rates and result rates. Additionally, we aimed to observe differences in false-positive results and describe a request-to-result ratio (RRR)-the required number of kit requests needed to obtain one successful result. METHODS: We reviewed data from an online postal STI kit requesting service for a client transitioning from MT to DBS blood collection systems. We described service user baseline characteristics and compared kit requests, kit and blood sample return rates, and the successful resulting rates for HIV and syphilis for MT and DBS. Pearson's χ2 and Fisher's exact test were used to determine statistical differences, and statistical formulae were applied to produce CIs for differences in proportions. RESULTS: 5670 STI postal kit requests from a Midlands region were reviewed from 6 September 2016-2 January 2019 (1515 MT and 4155 DBS). Baseline characteristics between the two groups were comparable (68.0% female, 74.0% white British and 87.5% heterosexual, median age 26 years). Successful processing rates for DBS were 94.6% and 54.4% for MT (p<0.001) with a percentage difference of 40.2% (95% CI 36.9% to 43.4%). The RRR for MT was 2.9 cf. 1.6 for DBS. False-positive results for MT samples were 5.2% (HIV) and 0.4% (syphilis), and those for DBS were 0.4% (HIV) and 0.0% (syphilis). CONCLUSIONS: This comparative analysis demonstrated the superior successful processing rates for postal DBS collection systems compared with MT. Reasons for this included insufficient volumes, high false-positive rates and degradation of blood quality in MT samples. A postal sampling service using DBS to screen for HIV, syphilis and other blood-borne viruses could be a viable alternative.

Epithelioid trophoblastic tumor with antecedent molar pregnancy in an HIV-positive patient.

Epithelioid trophoblastic tumor (ETT) is a rare malignancy arising from neoplastic proliferation of chorionic-type intermediate trophoblasts. ETT poses significant challenges to clinicians in the diagnosis and treatment and can hence lead to a poor prognosis. We report a unique case of metastatic ETT in a HIV-positive patient.

Acquired epidermodysplasia verruciformis in an HIV-positive patient.

Epidermodysplasia verruciformis (EV) is a rare dermatological manifestation of the human papillomavirus (HPV) infection, which causes distinctive skin lesions in sun-exposed areas. Both inherited and acquired forms exist. Immunocompromised individuals, such as HIV patients, are at risk of acquired EV. EV poses challenges in its management and variable responses are seen in different individuals. In addition, EV carries a significant risk of skin malignancy with certain HPV types that require skin surveillance. A case of acquired EV in a HIV-positive patient is presented in this report.
