An evaluation of global Chikungunya clinical management guidelines: A systematic review.

Background: Chikungunya virus (CHIKV) has expanded its geographical reach in recent decades and is an emerging global health threat. CHIKV can cause significant morbidity and lead to chronic, debilitating arthritis/arthralgia in up to 40% of infected individuals. Prevention, early identification, and clinical management are key for improving outcomes.

Infectious Proctitis due to Human Mpox.

We describe 2 cases of infectious proctitis secondary to human monkeypox in patients presenting with rectal pain. These cases highlight the importance of multidisciplinary management of monkeypox and in expanding case definitions and enabling clinical recognition in patients presenting without skin rash.

Availability, scope and quality of monkeypox clinical management guidelines globally: a systematic review.

Background: Monkeypox (MPX) is an important human Orthopoxvirus infection. There has been an increase in MPX cases and outbreaks in endemic and non-endemic regions in recent decades. We appraised the availability, scope, quality and inclusivity of clinical management guidelines for MPX globally.

Demographic and clinical characteristics of confirmed human monkeypox virus cases in individuals attending a sexual health centre in London, UK: an observational analysis.

Background: Historically, human monkeypox virus cases in the UK have been limited to imported infections from west Africa. Currently, the UK and several other countries are reporting a rapid increase in monkeypox cases among individuals attending sexual health clinics, with no apparent epidemiological links to endemic areas. We describe demographic and clinical characteristics of patients diagnosed with human monkeypox virus attending a sexual health centre.

Antiretroviral drug switches to zidovudine-based regimens and loss to follow-up during the first COVID-19 lockdown in Bali, Indonesia.

Objectives: International lockdowns during the COVID-19 pandemic impacted antiretroviral drug supplies in Indonesia. We assessed the impact of antiretroviral treatment (ART) provision and being lost to follow-up (LTFU) on people living with HIV, attending a key population-focused HIV clinic in Denpasar, Bali.

Methods: This was a retrospective note review of anonymized data from adult Indonesian patients living with HIV.

The success of HIV combination prevention: The Dean Street model.

The 56 Dean Street combination prevention model, a strong engagement with the LGBTQI community and flexible services adapted to users' changing needs led to an 80% drop in HIV diagnoses in gay, bisexual and other men who have sex with men (GBMSM) from 2015 to 2017. We describe the service changes at 56 Dean Street since 2012 which resulted in an increase in the frequency of HIV testing, the introduction of pre-exposure prophylaxis, earlier HIV diagnosis and a shorter time to viral suppression in those living with HIV. This model could be adapted to deliver similar results in those settings of high HIV prevalence among GBMSM and where access to technological innovation in healthcare and engagement with the community can be achieved.

Getting Indonesia's HIV epidemic to zero? One size does not fit all.

Indonesia has one of the fastest growing HIV epidemics in the world. AIDS related deaths in Indonesia have not fallen and have increased significantly since 2010. HIV infection rates remain high and rising in key affected populations.

Evolution of a pre-exposure prophylaxis (PrEP) service in a community-located sexual health clinic: concise report of the PrEPxpress.

Screening and treatment of sexually transmissible infections, including HIV, are free in the UK nations; pre-exposure prophylaxis (PrEP) became free in England in October 2017 through the PrEP Impact trial. Doctor-led PrEP clinics started at 56 Dean Street in September 2015, with the drug purchased privately at full price. The service was expanded to other staff to support initiation and monitoring of increasing numbers of attendees purchasing PrEP from online pharmacies.

¹⁸F-FDG PET/CT in HIV-related central nervous system pathology.

Purpose: To evaluate the utility of ¹⁸F-FDG PET/CT in suspected cerebral pathology in HIV-infected individuals.

Methods: ¹⁸F-FDG PET/CT scans from 29 HIV-infected individuals (29 brain scans, 22 whole-body scans) who presented with neurological symptoms and signs were retrospectively reviewed and compared with subsequent clinical investigations.

Results: The majority of patients (n=25) were referred to differentiate infection from malignant causes of cerebral pathology.

Pharmacokinetics of abacavir and its anabolite carbovir triphosphate without and with darunavir/ritonavir or raltegravir in HIV-infected subjects.

Background: Here, we aimed to investigate the pharmacokinetics of abacavir and carbovir triphosphate (CBV-TP) with darunavir/ritonavir 900/100 mg once daily or raltegravir 400 mg twice daily.

Methods: HIV-infected subjects on abacavir (600 mg once daily) underwent steady-state pharmacokinetic assessments without and with darunavir/ritonavir or raltegravir. Within-subject changes in plasma and intracellular pharmacokinetic parameters were evaluated by geometric mean ratios (GMRs) and 90% CIs.

Plasma and intracellular pharmacokinetics of darunavir/ritonavir once daily and raltegravir once and twice daily in HIV-infected individuals.

Objectives: To investigate the pharmacokinetics of darunavir/ritonavir and raltegravir, in HIV-infected subjects, in both plasma and at the intracellular (IC) site of action.

Methods: HIV-infected patients on antiretroviral therapy received raltegravir 400 mg twice daily for 21 days (period 1); darunavir/ritonavir 800/100 mg once daily was added for 14 days (period 2), and patients were randomized to continue raltegravir twice daily (group 1) or to switch to 800 mg once daily (group 2), then they all stopped raltegravir intake and continued darunavir/ritonavir once daily for 14 days (period 3). Drug concentrations in plasma and cells (peripheral blood mononuclear cell) were measured, and differences in geometric mean ratios (GMR) and 90% confidence intervals (CI) between period 2 versus period 3 and period 2 versus period 1 were assessed.
