Item Causes, complications and short-term outcome of acute Kidney injury in a resource-limited setting(SAGE-Hindawi Access to Research, 2024-12) Herath, N.; De Silva, S.; Liyanage, P.; Kumara, S.; Devi, S.; Abeysekara, V.; Mallawarachi, R.; Perera, S.; Karunathilaka, I.; Samarasinghe, S.; Weerakoon, K.AIMS The outcome of acute kidney injury (AKI) depends on causes, patient factors and care received. We studied the causes, complications and 90-day outcomes of patients with AKI at a tertiary referral centre in Sri Lanka. METHODS Patients aged 18 years or older with AKI referred to nephrology services were analysed retrospectively. AKI severity was assessed using the KDIGO classification. Information was gathered from hospital and clinic records. RESULTS Of the 464 patients studied, 262 (56.5%) were males. The mean age of the study sample was 57.04 (SD 16.85) years. The majority (212-45.69%) were discharged with normal renal functions, 173 (37.28%) were discharged with impaired functions, and 79 (17.03%) died during hospital stay. There were 377 patients at 3 months follow-up; 331 (87.8%) had normalised renal function, 40 (10.6%) had not recovered fully and 6 (1.6%) had succumbed. Progression of AKI to chronic kidney disease or death was significantly high in patients aged > 60 years (p=0.017). More severe AKI was associated with type 2 diabetes (p=0.0042), hypertension (p < 0.0001) and multiple comorbidities (p=0.0014). Persons with no comorbidities had less severe AKI (p=0.0004). Even in the early stages of AKI, there was significantly high mortality (11% in AKI stages 1 and 2) which doubled in stage 3 (22%). Mortality was low in patients with prerenal causes of AKI (OR: 0.59, 95% CI: 0.35-0.99 and p=0.047). CONCLUSIONS AKI in elderly and comorbid patients has high morbidity and mortality. Identification of individuals who are at high risk of developing AKI is important for its prevention, early diagnosis and proper treatment. Limitations in infrastructure, manpower, local research, reporting and recording of AKI are key challenges in providing optimal care for AKI in Sri Lanka.Item Survey on the psychosocial impact of COVID-19 on the Sri Lankan mental healthcare system and the needs of frontline healthcare workers in the post-covid era(Sri Lanka Medical Association, 2023) Wijesinghe, C.; Chandradasa, M.; Ranwella, P.; Samaranayake, A.; Wickrama, P.; Gamage, N.; Siriwardane, G.; Goonathilake, N.; Perera, S.; Dahanayake, D.; Mendis, J.; Kapila, R.INTRODUCTION: The COVID-19 pandemic severely strained the health care in Sri Lanka. The subsequent economic crisis compounded this issue. Priority was given to treating those afflicted with COVID-19 and preventing its spread, and healthcare staff faced immense difficulties dealing with the situation. The psychosocial impact of COVID on health care staff has not been properly assessed or addressed. OBJECTIVES: A study was conducted to identify the psychosocial impact of COVID-19 among four different categories of health care workers, and perform a needs assessment among these groups. METHODS: A convenient sample of frontline health workers, mental health teams, 1926 mental health helpline workers and 1990 Suwa Sariya emergency ambulance service staff were assessed via a self-administered questionnaire for mental health impact, work capacities and needs. RESULTS: Among frontline workers (n=188), 42.5% experienced anxiety symptoms, 12.8% depressive symptoms and 4.1% suicidal thoughts. Most (58.9%) lacked a psychological support system at the workplace. Only 20% have accessed specific programs or services at their workplace to obtain support for mental health issues, and all have benefitted from them. All categories of health workers lacked training and resources. CONCLUSION: The findings demonstrate that a significant amount of health care workers undergo psychological problems in the course of their work especially in the aftermath of the COVID-19 pandemic. The analysis reveals that Sri Lanka lacks structured psychological support systems for health workers and needs more resources and training. Psychological support for health workers through strengthening resources and training should be prioritised when planning service development.Item Transfusion-transmitted Hepatitis C: A cluster of cases in transfusion-dependent Thalassaemia patients in Sri Lanka(Blackwell Scientific Publications,, 2020) Perera, S.; Bonsall, D.; Niriella, M.A.; Allen, A.; Peries, A.C.; Nelumdeniya, U.B.; Dissanayake, R.; Silva, I.; de Cesare, M.; Klenerman, P.; Weatherall, D.J.; Roberts, D. J.; Premawardhena, A.P.OBJECTIVES: To report the clinical and virologic epidemiology of a recent epidemic of hepatitis C in thalassaemia patients in Sri Lanka. BACKGROUND: Transfusion-dependent thalassaemia patients remain at risk for hepatitis C virus (HCV). Here, we report a cluster of recent HCV infections in Sri Lankan thalassaemia patients and examine the phylogenetic relationship of viral sequences. METHODS: We conducted two prospective cross-sectional surveys of 513 patients in four Sri Lankan thalassaemia centres in 2014/2015 and re-surveyed one centre in 2016. We screened for anti-HCV antibodies using the CTK Biotech enzyme-linked immunosorbent assay (ELISA) kits and confirmed active infection by reverse transcription-polymerase chain reaction (RT-PCR) for HCV-RNA. HCV genomes were sequenced by unbiased target enrichment. RESULTS: Anti-HCV antibodies were found in 116/513 (22.6%) of patients initially tested. Active hepatitis C infection was found in 26 patients with no cases of active hepatitis B infection. Of 26 patients with HCV, two were infected with genotype 1(a), and the rest had 3(a). In a single centre (Ragama), 122 patients (120 new cases and two previously tested, but negative) were retested for anti-HCV antibodies. 32/122 (26.2%) patients were seropositive. Twenty-three (23/122; 18.8%) of these new cases were confirmed by HCV PCR (all genotype 3[a]). CONCLUSIONS: There is a significant cluster of recent HCV cases in multiply transfused thalassaemia patients in several centres in Sri Lanka. Most of the viruses shared a close phylogenetic relationship. The results are consistent with recent continuing transfusion-transmitted HCV infection. Routine surveillance for HCV of chronically transfused patients is required irrespective of screening of blood products.
