Epidemiology and Trends of Infective Meningitis in Neonates and Infants Less than 3 Months Old in Hong Kong.

OBJECTIVES: Meningitis in neonates and young infants leads to significant morbidity and mortality worldwide. This study aimed to investigate pathogens, antibiotic resistance and secular change of incidence in Hong Kong. METHODS: A retrospective search was performed on meningitis in neonates and infants aged <3 months in three Hong Kong public hospitals from 2004 to 2019. Medical charts were reviewed, with focus on the identification and antibiotic resistance of the pathogens. RESULTS: A total of 200 cases of meningitis were identified (67% were bacterial). Group B Streptococcus (GBS) and Escherichia coli (E. coli) were the commonest bacterial pathogens. The annual rates of early-onset GBS meningitis decreased after the implementation of universal GBS screening and intrapartum antibiotic prophylaxis (IAP) in 2012, while that of late-onset GBS meningitis remained similar. A significant portion of E. coli isolates were resistant to ampicillin and/or gentamicin. CONCLUSION: GBS and E. coli were the most common bacteria for meningitis in this age group. The annual rate of bacterial meningitis in Hong Kong has declined in recent years, which has been attributed to the decline in early-onset GBS meningitis due to universal GBS screening and IAP. Antimicrobial-resistant bacterial strains that cause meningitis require further clinical and public health attention.

The unmet provision of allergy services in Hong Kong impairs capability for allergy prevention-implications for the Asia Pacific region.

INTRODUCTION: There is a high and rising prevalence of many allergic diseases in the Asia Pacific, including Hong Kong (HK), which is unmatched by a commensurate provision of clinical allergy services. METHOD: This review highlights progress and deficiencies in allergy service and training in HK. The allergy work force was estimated from the numbers of doctors practicing allergy registered with the HK Medical Council Specialist Register in Immunology and Allergy; Paediatric Immunology and Infectious Diseases (includes allergy); Paediatrics; and Immunology (as a discipline of Pathology). The numbers of trainees were estimated from the trainee lists of the Hong Kong Colleges of Physicians, Paediatrics and Pathology. The numbers of allergy clinics were estimated from existing services in Hospital Authority public hospitals in HK. RESULTS: In the last 3 years, two new drug allergy clinics have been established in public hospitals, and for the first time in 20 years, Hong Kong has a trainee in adult allergy. The current ratio of allergists per head of population has improved slightly from 1:1.46 million in 2014 to 1:1.17 million, but it is still low compared to many countries. There are 5-fold more paediatric allergists than adult allergists per head of population in HK. DISCUSSION: Hong Kong is not equipped to take advantage of major public health advances in allergy prevention. If the unbalance of adult to paediatric allergists remains uncorrected, continuing care for allergic children as they grow into adulthood will be an increasing problem. CONCLUSION: Hong Kong still has an unmet need for allergy specialists and is ill equipped to exploit recently discovered public health opportunities to prevent allergy. This review provides recommendations to improve allergy service provision and training, including the creation of Centres of Excellence in allergy to drive the growth of the specialty.
