Joint Replacement Surgeries Can Be Safely Performed in HIV Patients

Whether joint replacement surgery can be performed safely on HIV patients is still a matter of debate. This study aimed to report the surgical efficacy and complications of joint replacement surgery in HIV patients. A total of 21 HIV patients and 27 non-HIV patients who underwent arthroplasties in our hospital were retrospectively reviewed. The 21 HIV patients received 29 joint replacement surgeries including 27 cases of total hip arthroplasty (THA) and 2 cases of total knee arthroplasty (TKA). The non-HIV patients received 16 THA, 10 TKA, and 3 unicompartmental arthroplasty (UKA). The length of hospital stay of HIV patients was significantly lower than that of non-HIV patients. At the last follow-up, there were no significant complications both in the HIV group and the non-HIV groups. No medical staff had any occupational exposure. We concluded that joint replacement surgery in HIV patients is safe and effective. Optimization of patients is key to treatment success. Strictly following the standardized protection protocol can prevent the risk of occupational exposure.

HIV post-exposure prophylaxis in the Emergency Department: a perspective from Singapore

Background:

Exposures to human immunodeficiency virus (HIV) commonly arrive at the Emergency Department (ED) for evaluation of transmission risk and the necessity for post-exposure prophylaxis (PEP). PEP aims to prevent HIV after exposure. International recommendations exist to guide eligibility assessment and standardise prescribing practices.

Objective:

The primary objective was to describe the patient cohort receiving HIV PEP at the ED. The secondary objective was to assess the ED physicians’ adherence to the 2005 guidelines provided by US Centers for Disease Control and Prevention for HIV PEP.

Methods:

This retrospective study identified patients prescribed with PEP after presenting with potential HIV exposure to a tertiary hospital ED in Singapore over 2 years. The exposure type and characteristics, source patient characteristics, indications for PEP, HIV status on presentation and on follow-up were assessed. Institutional guidelines recommended tenofovir/emtricitabine (Truvada) and raltegravir as HIV PEP.

Results:

Twenty-seven patients received HIV PEP during the study period. The majority (81.5%) presented after occupational exposure, with fresh needlestick injury (44.4%) being the most common cause. Amongst all recipients, PEP was indicated in 22.2% and not in 18.5%.

Conclusions:

With international guidelines simplifying eligibility assessment and prescribing practices, accurate and evidence-based PEP provision should be implemented at the frontline in the ED. These may be encouraged by enforcement of specific workflows and physician education.

The risks of surgery in HIV-infected patients

There are increasing demands for surgical interventions in Human Immunodeficiency Virus (HIV)-infected patients as a consequence of antiretroviral therapy. This article will discuss various risk factors involved in the surgical management of patients with HIV infection including: anaesthetic and surgical risk to patients with HIV infection undergoing surgical procedures; risk to healthcare professionals involved in the treatment of HIV-infected patients; and measures taken to ensure a safe and optimal outcome from surgery.
