Item The Impact of empirical hydrocortisone therapy on clinical outcomes in dengue fever: A retrospective chart review(Oxford University Press, 2020) de Mel, S.; Thilakawardana, B.U.; de Mel, P.; de Silva, A.P.; de Mel, C.; Chandrasena, L.; Seneviratne, S.L.; Abeysuriya, V.BACKGROUND: The role of steroids in dengue infection (DI) remains uncertain. METHODS: A retrospective chart review was conducted on patients ≥18 y of age diagnosed with DI based on positivity for dengue non-structural antigen 1 or immunoglobulin M between October 2017 and November 2018. RESULTS: Hydrocortisone was administered to 106 of 406 patients. DI with warning signs occurred in nine patients (9.5%) in the steroid cohort and eight patients (2.5%) in the non-steroid group. The incidence of severe DI, bleeding and admission duration were similar between the groups. CONCLUSIONS: Our study shows no significant benefit of empirical steroids in DI.

However there are few epidemiological data from the region. METHODS: To determine prevalence and clinical characteristics of IBD, a hospital-based survey was performed in the Colombo and Gampaha districts (combined population 4.5 million) in Sri Lanka. Patients with established ulcerative colitis (UC) and Crohn's disease (CD), who were permanent residents of these adjoining districts, were recruited from hospital registries and out-patient clinics. Clinical information was obtained from medical records and patient interviews. RESULTS: There were 295 cases of IBD (UC = 240, CD = 55), of which 34 (UC = 30, CD = 4) were newly diagnosed during the study year. The prevalence rate for UC was 5.3/100,000 (95% CI 5.0-5.6/100,000), and CD was 1.2/100,000 (95% CI 1.0-1.4/100,000). The incidence rates were 0.69/100,000 (95% CI 0.44-0.94/100,000) for UC and 0.09/100,000 (95% CI 0.002-0.18/100,000) for CD. Female:male ratios were 1.5 for UC and 1.0 for CD. Mean age at diagnosis was (males and females) 36.6 and 38.1y for UC and 33.4 and 36.2y for CD. Among UC patients, 51.1% had proctitis and at presentation 58.4% had mild disease. 80% of CD patients had only large bowel involvement. Few patients had undergone surgery. CONCLUSIONS: The prevalence of IBD in this population was low compared to Western populations, but similar to some in Asia. There was a female preponderance for UC. UC was mainly mild, distal or left-sided, while CD mainly involved the large bowel.
