ABSTRACT
BACKGROUND AND OBJECTIVES: Paediatric dengue-associated acute liver failure (PALF) is a rare and fatal complication. To date, clinical data regarding the combination of therapeutic plasma exchange (TPE) and continuous renal replacement therapy (CRRT) for the treatment of dengue-associated PALF are limited. METHODS: We conducted a single-center, retrospective study of all children with dengue-associated PALF admitted to the paediatric intensive care unit of Children Hospital No.2, Vietnam, who were treated with TPE+CRRT between January 2021 and March 2022. The main study outcomes were in-hospital survival, normalisation of hepatic function, and hepatic encephalopathy improvement. RESULTS: Twelve patients aged from 06 to 12 years underwent TPE+CRRT procedures. Among them, three (25 %) patients died of severe sepsis and septic shock confirmed by Enterobacteriaceae spp. haemocultures (stable on maintenance treatment of COVID-19-associated MIS-C with low dose of oral steroids on hospital admission), acute respiratory distress syndrome (ARDS), and clinically apparent intracranial haemorrhage. Nine patients (75 %) survived. The paediatric mortality risk score improved significantly at discharge compared with PICU admission (P < 0.01). Markedly, all twelve patients were diagnosed with hepatoencephalopathy of grades III and IV on PICU admission. After the combined TPE+CRRT interventions, there were substantial improvements in liver transaminases levels, coagulation profiles, and metabolic biomarkers. Normal neurological functions were observed in nine alive patients at hospital discharge. Only one patient experienced an adverse event of slightly low blood pressure, which rapidly self-resolved. INTERPRETATION AND CONCLUSIONS: Combined TPE+CRRT significantly improved survival outcome, neurological status, and rapid normalisation of liver functions in dengue-associated PALF.

BACKGROUND AND OBJECTIVES: It is proposed that severe leucocytosis mainly contributes to pulmonary hypertension by blocking pulmonary capillaries and restricting blood flow. Exchange transfusion (ET) in pertussis has been demonstrated as a safe and useful technique for depleting the leucocyte mass. We aim to discuss four cases of pertussis-induced respiratory distress and the effectiveness of ET in such a setting. MATERIALS AND METHODS: We conducted a retrospective case series at the Infectious Disease Department of Children's Hospital 2 in Ho Chi Minh City, Vietnam, and included four pertussis patients that were confirmed by PCR tests on respiratory secretions, presented with severe leucocytosis and respiratory distress and required mechanical ventilation. RESULTS: Among the included patients, three underwent a double volume ET for leucodepletion, two of whom were discharged after the procedure with proper vitals and laboratory test results. On the other hand, one patient died despite ET, performed late in the course of the disease. Exchange transfusion was not performed in the last patient who died as well. CONCLUSION: Early ET may be a useful and rapid life-saving treatment in children with critical pertussis and severe leucocytosis before cardiopulmonary complications appear.

This study aims to assess the prevalence of underweight, overweight and obesity among adults in urban Hanoi, Vietnam; and compare these results to previous estimates among adults in urban Ho Chi Minh City. Survey participants were residents in urban Hanoi, Vietnam and aged between 25-74 years. Data from a cross-sectional biomedical survey conducted in 2004 were collected; which included a questionnaire, physical examination and blood tests. The age-standardised prevalence of overweight and obesity in 2004, using Asian-specific body mass index cut-offs, were 28.6% and 2.1%, respectively. The prevalence of overweight/obesity (combined) was similar in males (29.7%) and females (31.5%), and generally increased with age. The prevalence of overweight/obesity was considerably lower if the standard cut-off values of the World Health Organization were used. The age-standardised prevalence of underweight was 13.3%; and that of 'increased risk'/'substantially increased risk' waist circumference (combined) was 27.9% in males and 25.7% in females, respectively. Almost one in three adults in urban Hanoi were overweight or obese in 2004 and more than one in ten were underweight (based on Asian-specific cut-off values). This prevalence of overweight/obesity is similar to that for adults in urban Ho Chi Minh City, but the prevalence of underweight is lower. While low body weight remains a concern, overweight and obesity are an increasing problem for urban Vietnamese adults.
