Trimethoprim-sulfamethoxazole (TMP-SMZ) is a commonly used antibiotic that has been associated with drug rash with eosinophilia and systemic symptoms (DRESS) syndrome. DRESS syndrome is characterised by fever, rash, lymphadenopathy, eosinophilia and one or more major organ involvement. Although rare, TMP-SMZ is a recognised cause of fulminant hepatic failure. We report a 17-year-old Chinese male adolescent who presented with fever, myalgia, generalised maculopapular rash and lymphadenopathy after taking TMP-SMZ for acne vulgaris. He subsequently developed hepatic encephalopathy and was worked up for urgent liver transplantation. He responded well to extracorporeal liver dialysis (originally intended as a bridging therapy) and subsequently recovered without the need for liver transplantation. This case report highlights the importance of early recognition of TMP-SMZ-induced DRESS syndrome and the need for early discontinuation of the drug in the affected patient. Extracorporeal liver dialysis and transplantation should be considered in the management of TMP-SMZ-induced fulminant hepatic failure.

INTRODUCTIONHepatic venous pressure gradient (HVPG) measurement is recommended for prognostic and therapeutic indications in centres with adequate resources and expertise. Our study aimed to evaluate the quality of HVPG measurements at our centre before and after introduction of a standardised protocol, and the clinical relevance of the HVPG to variceal bleeding in cirrhotics.
METHODSHVPG measurements performed at Singapore General Hospital from 2005-2013 were retrospectively reviewed. Criteria for quality HVPG readings were triplicate readings, absence of negative pressure values and variability of ≤ 2 mmHg. The rate of variceal bleeding was compared in cirrhotics who achieved a HVPG response to pharmacotherapy (reduction of the HVPG to < 12 mmHg or by ≥ 20% of baseline) and those who did not.
RESULTS126 HVPG measurements were performed in 105 patients (mean age 54.7 ± 11.4 years; 55.2% men). 80% had liver cirrhosis and 20% had non-cirrhotic portal hypertension (NCPH). The mean overall HVPG was 13.5 ± 7.2 mmHg, with a significant difference between the cirrhosis and NCPH groups (p < 0.001). The proportion of quality readings significantly improved after the protocol was introduced. HVPG response was achieved in 28 (33.3%, n = 84) cirrhotics. Nine had variceal bleeding over a median follow-up of 29 months. The rate of variceal bleeding was significantly lower in HVPG responders compared to nonresponders (p = 0.025).
CONCLUSIONThe quality of HVPG measurements in our centre improved after the introduction of a standardised protocol. A HVPG response can prognosticate the risk of variceal bleeding in cirrhotics.

In this paper, we aimed to provide professional guidance to practising gastrointestinal (GI) endoscopists for the safe conduct of GI endoscopy procedures during the current coronavirus disease 2019 (COVID-19) pandemic and future outbreaks of similar severe respiratory tract infections in Singapore. It draws on the lessons learnt during the severe acute respiratory syndrome (SARS) epidemic and available published data concerning the COVID-19 pandemic. It addresses measures before, during and after endoscopy that must be considered for both non-infected and infected patients, and provides recommendations for practical implementation.

In this paper, we aim to provide professional guidance to clinicians who are managing patients with chronic liver disease during the current coronavirus disease 2019 (COVID-19) pandemic in Singapore. We reviewed and summarised the available relevant published data on liver disease in COVID-19 and the advisory statements that were issued by major professional bodies, such as the American Association for the Study of Liver Diseases and European Association for the Study of the Liver, contextualising the recommendations to our local situation.
