(Springer, 2023) Maiwall, R.; Pasupuleti, S.S.R.; Choudhury, A.; Kim, D.J.; Sood, A.; Goyal, O.; Midha, V.; Devarbhavi, H.; Arora, A.; Kumar, A.; Sahu, M.K.; Maharshi, S.; Duseja, A.K.; Singh, V.; Taneja, S.; Rao, P.N.; Kulkarni, A.; Ghazinian, H.; Hamid, S.; Eapen, C.E.; Goel, A.; Shreshtha, A.; Shah, S.; Hu, J.; Prasad, V.G.M.; Yuemin, N.; Shaojie, X.; Dhiman, R.K.; Chen, T.; Ning, Q.; Panackel, C.; Niriella, M.A.; Lama, T.K.; Tan, S.S.; Dokmeci, A.K.; Shukla, A.; Sharma, M.K.; Sarin, S.K.
BACKGROUND AND AIM: Acute-on-chronic liver failure (ACLF) is a severe form of alcoholic hepatitis (SAH). We aimed to study the natural course, response to corticosteroids (CS), and the role of the Asian Pacific Association for the Study of Liver (APASL) research consortium (AARC) score in determining clinical outcomes in AH patients. METHODS: Prospectively collected data from the AARC database were analyzed. RESULTS: Of the 1249 AH patients, (aged 43.8 ± 10.6 years, 96.9% male, AARC score 9.2 ± 1.9), 38.8% died on a 90 day follow-up. Of these, 150 (12.0%) had mild-moderate AH (MAH), 65 (5.2%) had SAH and 1034 (82.8%) had ACLF. Two hundred and eleven (16.9%) patients received CS, of which 101 (47.87%) were steroid responders by day 7 of Lille's model, which was associated with improved survival [Hazard ratio (HR) 0.15, 95% CI 0.12-0.19]. AARC-ACLF grade 3 [OR 0.28, 0.14-0.55] was an independent predictor of steroid non-response and mortality [HR 3.29, 2.63-4.11]. Complications increased with degree of liver failure [AARC grade III vs. II vs I], bacterial infections [48.6% vs. 37% vs. 34.7%; p < 0.001); extrahepatic organ failure [66.9% vs. 41.8% vs. 35.4%; p < 0.001] respectively. The AARC score better discriminated 90-day mortality. Harrell's C-index was 0.72 compared to other scores. CONCLUSION: Nearly 4 of 5 patients with AH present with ACLF. Such patients have a higher risk of infections, organ failures, lower response to CS, and higher mortality. Patients with AH and ACLF with AARC grade 3 should be considered for an early liver transplant.
Acute Dermato-Lymphangio-Adenitis Following Administration of Infliximab for Crohn's Disease.
(American College of Gastroenterology, 2019) Liyanage, I.K.; Niriella, M.A.; de Silva, A.P.; de Silva, N.; de Silva, H.J.
Tumor necrosis factor-α inhibitor (TNF-α) is frequently used for Crohn's disease and other autoimmune conditions. Increased risk of infection is an accepted adverse effect of TNF-α, and routine screening for potential infections are carried out before initiation of therapy. We report the case of a patient who developed a localized painful swelling near the injection site, which was diagnosed as acute dermato-lymphangio-adenitis due to filarial infection. This adds to the limited number of case reports on parasitic complications following TNF-α therapy

The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. With international groups volunteering to join, the "APASL ACLF Research Consortium (AARC)" was formed in 2012, which continued to collect prospective ACLF patient data. Based on the prospective data analysis of nearly 1400 patients, the AARC consensus was published in 2014. In the past nearly four-and-a-half years, the AARC database has been enriched to about 5200 cases by major hepatology centers across Asia. The data published during the interim period were carefully analyzed and areas of contention and new developments in the field of ACLF were prioritized in a systematic manner. The AARC database was also approached for answering some of the issues where published data were limited, such as liver failure grading, its impact on the 'Golden Therapeutic Window', extrahepatic organ dysfunction and failure, development of sepsis, distinctive features of acute decompensation from ACLF and pediatric ACLF and the issues were analyzed. These initiatives concluded in a two-day meeting in October 2018 at New Delhi with finalization of the new AARC consensus. Only those statements, which were based on evidence using the Grade System and were unanimously recommended, were accepted. Finalized statements were again circulated to all the experts and subsequently presented at the AARC investigators meeting at the AASLD in November 2018. The suggestions from the experts were used to revise and finalize the consensus. After detailed deliberations and data analysis, the original definition of ACLF was found to withstand the test of time and be able to identify a homogenous group of patients presenting with liver failure. New management options including the algorithms for the management of coagulation disorders, renal replacement therapy, sepsis, variceal bleed, antivirals and criteria for liver transplantation for ACLF patients were proposed. The final consensus statements along with the relevant background information and areas requiring future studies are presented here.
Alanine Transaminase (ALT) levels in normal adult Sri Lankans
(American Gastroenterological Association(AGA) Institute, Published by Elsevier Inc., 2009) Niriella, M.A.; Dassanayake, A.S.; Kalubowila, K.; Kalubowila, U.; de Silva, A.P.; Wickremasinghe, A.R.; Kato, N.; Makaya, M.; de Silva, H.J.
BACKGROUND : Alanine transaminase (ALT) levels are widely used in screening for liver disease.The upper limit of normal (ULN) of ALT (males 30 IU/l, females 19 IU/l) have been definedfor western populations. Normal levels have not been established for Asian populations. OBJECTIVES: To establish levels of ALT for a normal, adult Sri Lankan population METHODS: This study was part of a community based investigation - Ragama Health Study (RHS). The study population consisted of 35-64 year old adults, selected using stratified random sampling. Consenting adults were screened by a structured interview, liver ultrasound and collection of 10 ml venous blood. The “normal” population was defined as those not using potentially hepatotoxic drugs, safe alcohol consumption (14 units/week for males, 7 units/week for females), absence of fatty liver, and being HBsAg and anti-HCVab negative. ALT levels were estimated by a kit using the Bergmeyer method. The 95th percentile of the ALT levels was taken as the ULN. RESULTS: 3012 subjects participated in the study. The ALT level (U/l) among 831 normal males (mean 36, median 30, SD 20, ULN 68) was significantly higher than that of the 885 normal females (mean 29, median 25, SD 13, ULN 53) (p<0.001,Student's t-test ). CONCLUSION: The ULN for ALT levels of a “normal” Sri Lankan population was higher than observed in western populations. The levels were higher in males. ULN for ALT may need to be redefined for different population groups.
Alcohol use and alcoholic fatty liver disease: a prospective, communitybased study among adults in an urban community in Sri Lanka
(The Sri Lanka Medical Association, 2022) Niriella, M.A.; Kasturiratne, A.; Beddage, T.; de Silva, S.T.; Dassanayake, A.S.; Pathmeswaran, A.; Wickremasinghe, A.R.; Kato, N.; de Silva, H.J.
Background: Data on alcoholic fatty liver (AFL) is limited. Therefore, we investigated alcohol use and AFL in a cohort of adults in an urban community in Sri Lanka. Methods: The study population (selected by age-stratified random sampling) was screened in 2007 (35-64 years) and re-evaluated in 2014. They were assessed by structured interviews, anthropometric measurements, liver-ultrasound, and biochemical and serological tests. AFL was diagnosed on ultrasound criteria, ‘unsafe’ alcohol consumption (Asian standards: males>14 units, females >7 units per week) and absence of hepatitis B/C markers. Controls were unsafe alcohol consumers who had no fatty liver on ultrasound. Results: 2985/3012 (99%) had complete data for analysis. 272/2985 (9.1%) were unsafe-drinkers in 2007 [males-270; mean-age-51.9, SD-8.0 years]. 86/272 (31.6%) had AFL [males-85; mean-age-50.2, SD-8.6 years]. Male gender [p<0.001], increased waist circumference (WC) [OR 4.9, p<0.01], BMI>23kg/m2 [OR 3.5, p<0.01] and raised alanine aminotransferase (ALT) [OR 2.8, p<0.01] were independently associated with AFL. 173/272 (63.6%) unsafe alcohol consumers from 2007 were re-evaluated in 2014. 134/173 had either had AFL or had changed to ‘safe’ or no alcohol consumption. 21/39 (53.8%) [males-21 (100%), meanage- 57.9, SD-7.9 years] who remained ‘unsafe’ alcohol users who had no fatty liver in 2007 developed AFL after 7-years (annual incidence 7.7%). On bivariate analysis, only male gender was associated with new-onset AFL. Of the 42 who had AFL at baseline but changed their drinking status from unsafe to safe or no alcohol, 6 had resolution of fatty liver in 2014. Conclusion: In this community-based study among adults from an urban community, unsafe alcohol use was found in 9.1%. Among unsafe alcohol users, the prevalence of AFL was 31.6% and the annual incidence of AFL was 7.7%. New-onset AFL was independently associated with male gender.
Anthropometric correlates of total body fat, visceral adiposity and cardio-metabolic health risk: a community cohort study of urban, adult Sri Lankans
(Sri Lanka Medical Association, 2016) Niriella, M.A.; de Silva, S.T.; Kasturiratne, A.; Kottachchi, D.; Ranawaka, U.K.; Dassanayake, A.S.; de Silva, A.P.; Pathmeswaran, A.; de Silva, H.J.
INTRODUCTION: Anthropometric measurements (AM) are used as proxies for more direct measurements of body fat (BF) and its distribution. Several studies have examined the association between AM, BF and health outcomes such as cardiovascular risk (CVR). However, correlation of such simple AM and advanced measures of BF and the ability of these to predict CVR has not been studied in community follow up studies. OBJECTIVES: To examine the relationship between simple and advanced anthropometric measurements and their ability to predict cardiovascular risk factors in an urban adult Sri Lankan population. METHOD: The data was collected from a community cohort of adults (aged 42-71 years) selected by age-stratified random sampling from electoral lists of the Medical Officer of Health area, Ragama. Individual simple measurements [body weight, height, waist circumference (WC), hip circumference (HC)], advanced measurements [total body fat (TBF), visceral fat percentage (VFP) by Omron® body fat monitor] and cardiovascular risk factors [blood pressure, HbA1c, triglycerides, low-density (LDL-C), high-density-lipoprotein cholesterol (HDL-C) level, cardio-metabloic risk (CMR) (2 or more risk factors)] were assessed and their relationships were examined. RESULTS: 2155 individuals [1244 (57.7%) women, mean age 59.2 years (SD, 7.7)] participated. Complete data were available for 2000 (92.8%) [1147 (57.4%) women, mean age 59.2 years (SD, 7.7)]. Mean (SD) for anthropometric measurements were: males WC-85.9 (10.8) cm, HC-93.4 (8.0) cm, WHpR (waist-to-hip ratio) -0.92 (0.06), WhtR (waist-to-height ratio) -0.52 (0.06), BMI (body mass index) -23.5 (3.8) kg/m2, TBF -27.0 (5.7)%, VFP -10.7 (5.2)%; females WC -84.8 (10.7) cm, HC-97.2 (9.5) cm, WHpR-0.87(0.08), WhtR-0.52 (0.07), BMI -25.4 (4.4) kg/m2, TBF -38.2 (4.2)%, VFP-9.6 (4.9)%. BMI and WC correlated well with VFP (Pearson’s r for males: 0.94 and 0.85, females: 0.96 and 0.78, respectively). In both sexes, increasing BMI, WC, WHtR, TBF and VFP, were significantly associated with higher risks of hypertension, diabetes, dyslipidemia and combined CMR (ROC area under the curve>0.6). CONCLUSIONS: In this cohort of urban, adult Sri Lanka, simple anthropometric measurements correlated strongly with VFP, and were equally good in predicting cardiovascular risk factors.
APASL clinical practice guidelines on the management of acute kidney injury in acute-on-chronic liver failure.
(Springer, 2024) Maiwall, R.; Singh, S.P.; Angeli, P.; Moreau, R.; Krag, A.; Singh, V.; Singal, A.K.; Tan, S.S.; Puri, P.; Mahtab, M.; Lau, G.; Ning, Q.; Sharma, M.K.; Rao, P.N.; Kapoor, D.; Gupta, S.; Duseja, A.; Wadhawan, M.; Jothimani, D.; Saigal, S.; Taneja, S.; Shukla, A.; Govil, D.; Pandey, G.; Madan, K.; Eapen, C.E.; Benjamin, J.; Chowdhury, A.; Salao, V.; Yang, J.M.; Hamid, S.; Shalimar; Jasuja, S.; Kulkarni, A.V.; Niriella, M.A.; Tevethia, H.V.; Arora, V.; Mathur, R.P.; Roy, A.; Jindal, A.; Saraf, N.; Verma, N.; Arka, D.; Choudhary, N.S.; Mehtani, R.; Chand, P.; Rudra, O.; Sarin, S.K.; Puri, P.; Singh, S.
Acute-on-chronic liver failure (ACLF) is a syndrome that is characterized by the rapid development of organ failures predisposing these patients to a high risk of short-term early death. The main causes of organ failure in these patients are bacterial infections and systemic inflammation, both of which can be severe. For the majority of these patients, a prompt liver transplant is still the only effective course of treatment. Kidneys are one of the most frequent extrahepatic organs that are affected in patients with ACLF, since acute kidney injury (AKI) is reported in 22.8-34% of patients with ACLF. Approach and management of kidney injury could improve overall outcomes in these patients. Importantly, patients with ACLF more frequently have stage 3 AKI with a low rate of response to the current treatment modalities. The objective of the present position paper is to critically review and analyze the published data on AKI in ACLF, evolve a consensus, and provide recommendations for early diagnosis, pathophysiology, prevention, and management of AKI in patients with ACLF. In the absence of direct evidence, we propose expert opinions for guidance in managing AKI in this very challenging group of patients and focus on areas of future research. This consensus will be of major importance to all hepatologists, liver transplant surgeons, and intensivists across the globe.
Are alanine transaminase (ALT) levels useful to screen for Non-alcoholic Fatty Liver Disease (NAFLD) in the community?
(Sri Lanka Medical Association, 2009) Niriella, M.A.; Dassanayake, A.S.; Kalubowila, K.V.U.; Rajindrajith, S.; de Silva, A.P.; Wickremasinghe, A.R.; Kato, N.; Makaya, M.; de Silva, H.J.
BACKGROUND: The value of ALT in screening for NAFLD is controversial. Furthermore, the upper limit of normal (ULN) ALT is defined for western populations but not Asian populations. Objectives: To establish ULN ALT for an urban adult Sri Lankan population, and assess its value in screening for NAFLD in that community. METHODS: This was part of a community based study on non-communicable diseases - the Ragama Health Study. 35-64y adults were selected using stratified random sampling. They were screened by structured interview and liver ultrasound, and 10ml venous blood .was obtained. "Normal" adults were defined as those not using potentially hepatotoxic drugs, drinking alcohol within safe limits, HBsAg and anti-HCV negative, and no fatty liver on ultrasound. NAFLD was diagnosed on established ultrasound criteria, .safe alcohol consumption and being HBsAg and anti-HCV negative. The 95th percentile of ALT was taken as the ULN for this population. RESULTS: 3012 subjects participated in the study. Those with NAFLD (n=930) and "normals" (n=1716) were matched for age and sex. ULN ALT (U/l) was significantly higher in normal males than females (68 vs. 53; p<0.001, Student's t-test). ALT was significantly higher in NAFLD than normals (p<0.001). However, ALT>ULN had a sensitivity [positive predictive value (PPV)] of only 14.5% (58%) for males and 11.5% (60%) for females with NAFLD. When ULN ALT cut offs for western populations (males 30 IU/1, females 19 IU/1) were used, although sensitivity considerably increased, the PPV to detect NAFLD decreased.further [sensitivity (PPV): males 79.4% (42%); females 94.6% (41%)]. CONCLUSIONS: Although ALT was significantly higher in NAFLD than in normal adults, it does not seem a useful test to screen for NAFLD in the community.

Asian Pacific association for the study of liver (APASL) guidelines: hepatitis B virus in pregnancy
(Springer,New York, 2022) Kumar, M.; Abbas, Z.; Azami, M.; Belopolskaya, M.; Dokmeci, A.K.; Ghazinyan, H.; Jia, J.; Jindal, A.; Lee, H.C.; Lei, W.; Lim, S.G.; Liu, C.J.; Li, Q.; Mahtab, M.A.; Muljono, D.H.; Niriella, M.A.; Omata, M.; Payawal, D.A.; Sarin, S.K.; Ségéral, O.; Tanwandee, T.; Trehanpati, N.; Visvanathan, K.; Yang, J.M.; Yuen, M.F.; Zheng, Y.; Zhou, Y.H.
Hepatitis B virus (HBV) infection still remains a major public health issue in the Asia-Pacific region. Most of the burden of HBV-related disease results from infections acquired in infancy through perinatal or early childhood exposure to HBV in Asia-Pacific. Hepatitis B during pregnancy presents unique management issues for both the mother and fetus. These APASL guidelines provide a comprehensive review and recommendations based on available evidence in the literature, for the management of females with HBV infection through every stage of pregnancy and postpartum. These also address the concerns, management challenges, and required follow-up of children born to hepatitis B-positive mothers.
Assessing liver fibrosis in patients with transfusion dependent beta thalassaemia - a predictive model
(Sri Lanka Medical Association, 2021) Padeniya, A.G.P.M.; Ediriweera, D.; de Silva, A.; Niriella, M.A.; Premawardhena, A.P.
Introduction and Objectives Liver fibrosis in β-thalassaemia major is mainly due to transfusion-related iron overload. Transient elastography (TE) is an imaging modality which measures liver stiffness/fibrosis non-invasively. TE is simple, safe and efficient. However, inaccessibility and high-cost hinders its routine use. We designed a predictive model to evaluate liver fibrosis using demographic, anthropometric, biochemical and imaging data. Methods Sixteen patients with transfusion dependent beta thalassaemia were recruited to the study. FBC, LFT, serum ferritin and Transient Elastography (TE) and FerriScan measurements were recorded at the baseline and after two years follow up. Multiple regression model was developed to predict liver fibrosis using demographic, anthropometric, biochemical and imaging data. [age, gender, body mass index (BMI), steatosis score, liver iron content, mean pre-Hb over the last year, no of blood transfusions (lifetime), amount of blood ingested over the last year(ml/kg), amount of elemental iron by transfusions over last year(mg/ kg), serum ferritin, SGOT, SGPT and compliance with iron chelation].Results Of 16, 8 (50%) were females, mean (SD) age, BMI and fibrosis scores were 21(4.3) years, 18.8 (2.8) kgm-2 and 9.7(5.7) kPa respectively. Gender, BMI, SGOT, SGPT, compliance, number of transfusions taken lifetime showed significant association with liver fibrosis. The final model showed a coefficient of determination (R2) of 0.859. According to the model, predicted liver fibrosis is given by;-26.18 - 4.38*male+1.01*BMI - 0.11*SGPT+0.32*SGOT+2.78*compliance (rps)+0.04*no. of transfusions. ConclusionThe suggested model is a reliable tool to predict liver fibrosis in transfusion-dependent β-thalassaemia major patients in resource poor settings.
Assessing motivation to lose weight: the psychometric properties of the Sinhala version of University of Rhode Island Change Assessment (URICA) scale
(Sri Lanka Medical Association, 2023) Niriella, M.A.; de Silva, S.T.; Hapangama, A.; Baminiwatta, A.; Fernando, R.; Ediriweera, D.
INTRODUCTION: Weight reduction through lifestyle modifications is an important component in the management of various chronic diseases. The degree of motivation to change has been shown to predict outcomes in weight reduction interventions. Thus, the availability of a validated self-report tool assessing the degree of motivation for weight management would be useful for both clinical and research purposes in Sri Lanka. OBJECTIVES: To examine the structural validity and internal consistency of the URICA for weight management in a sample of Sri Lankan adults with chronic medical conditions. METHODS: Standard procedures for cross-cultural adaptation of a questionnaire were followed in translating the 32-item URICA into Sinhala. The Sinhala version was administered to 208 patients aged 18-60 years attending outpatient clinical services for non-disabling chronic medical diseases. Psychometric testing included confirmatory factor analysis and the assessment of internal consistency (Cronbach α). RESULTS: The commonly accepted four-factor structure of URICA reflecting Prochaska and Di Clemente’s transtheoretical model (pre-contemplation, contemplation, action and maintenance) showed good model fit, after the removal of four items from the pre-contemplation subscale due to inadequate factor loadings (<0.4). In line with theory, factor correlations indicated that the pre-contemplation factor was inversely correlated with the other three factors, while the other three factors were positively correlated with one another. All four subscales showed good internal consistency (Cronbach α ranging from 0.73 to 0.89). CONCLUSIONS: The Sinhala version of a modified 28-item URICA was found to have sound psychometric properties as a measure of motivation for weight management among Sinhala-speaking adult patient.
Assessing reversibility of liver fibrosis in patients with transfusion-dependent beta thalassaemia following intensive chelation
(Sri Lanka Medical Association, 2023) Padeniya, A.G.P.M.; Ediriweera, D.; Niriella, M.A.; de Silva, A.; Premawardhena, A.P.
INTRODUCTION: Transfusion-related iron overload is a leading cause of hepatic fibrosis in transfusion-dependent thalassaemia (TDT). OBJECTIVES: This study aimed to evaluate the reversibility of liver fibrosis with intensive chelation therapy in TDT. METHODS: Forty-five patients were included. Serum ferritin, hepatic fibrosis & steatosis (assessed by Transient Elastography), and liver iron concentration/LIC (estimated by FerriScan) were recorded at recruitment and after 2 ½ years of intensive chelation. Compliance for iron chelators was monitored and recorded as good (gc), moderate compliance (mc), and poor (pc) compliance based on the number of days the iron chelators were used. RESULTS: 22/45 (49%) were males [mean age (SD)-19 (4.78) years]. There were 23 (51%), 12 (27%), and 10 (22%) patients with gc, mc, and pc with iron chelators, respectively. The LIC decreased in 36 (80%) patients. The median LIC reduction after 2 ½ years was as follows: gc group-13.5 to 5.1 mg Fe/g dw (P=0.0002); mc group-25.5 to 17.75 mg Fe/g dw (P=0.001). In the pc group, the LIC increased by 10.4 mg Fe/g dw (P =0.058). Liver fibrosis declined in 23 (51%) patients. The liver stiffness at recruitment and after 2 ½ years was 7.6 and 7.1 kPa (P=0.08) in the gc group. In both mc and pc groups, liver fibrosis increased on follow-up [significantly worsened in the pc group (P=0.04)]. CONCLUSION: The reduction of LIC in TDT was related to compliance with chelation therapy; substantial reductions were achieved in those with gc and mc. However, only those with gc managed to arrest the fibrosis progression.
Association between road accidents and low-grade hepatic encephalopathy among Sri Lankan drivers with cirrhosis: a prospective case control study
(Biomed Central, 2016) Subasinghe, S.K.C.E.; Nandimuni, Y.; Ranasinghe, S.; Niriella, M.A.; Miththinda, J.K.N.D.; Dassanayake, A.S.; de Silva, A.P.; de Silva, H.J.
BACKGROUND: Low-grade hepatic encephalopathy (LGHE) comprises minimal hepatic encephalopathy (MHE) and grade 1 hepatic encephalopathy. LGHE has no or minimal recognizable symptoms but has mild cognitive and psychomotor deficits. Studies in Western countries have demonstrated increased road accidents (RA) among patients with MHE. Our objective was to investigate the association between Sri Lankan LGHE phenotype and RA. STUDY DESIGN AND METHODS: A prospective, case–control study was conducted in the University Medical Unit, North Colombo Teaching Hospital, Ragama Sri Lanka. Patients with cirrhosis of any aetiology, without OHE, who had been driving during previous 1 month were included. A similar number of age matched, healthy control drivers were also enrolled. Both groups were subjected to five pencil-paper based psychometric tests used to detect LGHE in cirrhotics. Self-reported RA during the previous 1 month were recorded: categorized as ‘major’ when resulted in hospitalization of the involved, ‘minor’ when there were injuries, but not serious enough for hospitalization of the involved and ‘other’ when limited to damages to vehicle or environment without injuries. RESULTS: Among 55 drivers with cirrhosis and LGHE [males, median age 53 years (range 30–60)], 7 (12.7 %) reported RA compared to 6 (10.9 %) among 55 controls [males; median age 51 years (range 30–60)]. There were no ‘major’ accidents in either group. 2/55 (3.6 %) cases and 2/55 (3.6 %) controls reported ‘minor’ accidents. CONCLUSION: There was no increased frequency of RA among Sri Lankan drivers with LGHE compared to healthy controls. This is with the limitation of the study based only on self reported RA.
Association between road accidents and minimal hepatic encephalopathy in a cohort of Sri Lankan cirrhotic drivers
(Wiley Blackwell Scientific Publications, 2014) Subasinghe, S.K.C.E.; Nandamuni, Y.; Ranasinghe, S.; Kodisinghe, K.; Niriella, M.A.; de Silva, A.P.; de Silva, H.J.
OBJECTIVE: Minimal hepatic encephalopathy (MHE) has no recognizable clinical symptoms of hepatic encephalopathy (HE) but has mild cognitive and psychomotor deficits which can interfere with executive decision making and psychomotor speed. It affects driving ability and previous studies in Western countries have demonstrated an association between MHE and increased road accidents. Our objective was to investigate this association in a cohort of Sri Lankan cirrhotic drivers. METHODS: A prospective, case controlled study ongoing study has been conducted in the Gastroenterology Clinic, University Medical Unit, North Colombo Teaching Hospital, Ragama, from August 2013. Patients with cirrhosis of any aetiology, without overt HE, who had been driving any vehicle during the past one month were subjected to 5 standard pencil-paper based psychometric tests used to detect MHE. Road accidents were recorded for both cirrhotic drivers with MHE and controls. Accidents were categorized as major when they resulted in hospitalization of the involved person/s, and minor when there were no serious injuries. RESULTS: Among 55 cirrhotic drivers with MHE [males, median age 53 years (range 30-60)], 7 (12.7%) reported any type of accident compared to 6 (10.9%) among 55 controls [males; median age 51 years (range 30-60)]. 2/55 (3.6%) cases and 2/55 (3.6%) controls reported minor accidents. There were no major accidents in either group. CONCLUSION: Preliminary results of this ongoing study do not indicate an increased frequency of road accidents in a cohort of Sri Lankan cirrhotic drivers with MHE

INTRODUCTION AND OBJECTIVES: Minimal hepatic encephalopathy (MHE) has no recognizable clinical symptoms of hepatic encephaiopathy (HE) but has mild cognitive and psychomotor deficits. Previous studies in Western countries have demonstrated an association between MHE and increased road accidents. Our objective was to investigate this association in a cohort of Sri Lankan drivers with cirrhosis. Study design; Prospective, case controlled study. Study setting; Ongoing study conducted in the Gastroenterology Clinic, University Medical Unit, North Colombo Teaching Hospital, Ragama, from August 2013. METHODS: Patients with cirrhosis of any aetiology, without overt HE, who had been driving any vehicle during the past one month were subjected to 5 standard pencil-paper based psychometric tests to detect MHE. An abnormality in 3 or more tests was considered diagnostic of MHE. Road accidents were recorded among drivers with cirrhosis with MHE. Age and sex matched healthy drivers (controls) who also underwent the 5 psychometric tests. RESULTS: Among 54 drivers with cirrhosis with MHE [males, median age 53 years (range 30-60}], 7 (13%) reported any type of accident compared to 6 (11%) among 54 controls [males; median age 51 years (range 30-60)]. 2 (3.7%) cases and 2 (3.7%) controls reported minor accidents involving another person. There were no major accidents in either group. CONCLUSIONS: Preliminary results of this ongoing study do not indicate an increased frequency of road accidents in a cohort of Sri Lankan drivers with cirrhosis with MHE.

INTRODUCTION: Non-alcoholic fatty liver disease is a leading cause for hepatocellular carcinoma (HCC) in Sri Lanka. Diabetes mellitus, alcohol abuse, and liver inflammation are known to increase the risk of HCC. The present study evaluates serum ferritin levels in a cohort of patients with non-viral HCC (nvHCC). METHODOLOGY: Consecutive patients with nvHCC presenting to the Colombo North Liver transplant Service, Ragama, from January 2012 to July 2013 were investigated. All were negative for hepatitis B and C. At registration, 5 mL of serum was separated into plain tubes, stored at -80°C and analysed for ferritin using an enzyme-linked immunosorbent assay. Correlation between the serum ferritin and patient risk factors, liver status, and tumour characteristics were analysed. RESULTS: There were 93 patients with nvHCC (median age 65 [12-82] years; 82 [88.2%] males). The median ferritin level was 246.2 μg/L, and 38 (40.86%) patients had elevated ferritin. Non-diabetics (median 363.5 mg/L, p = 0.003) and alcohol abusers (median 261.2 mg/L, p = 0.018) had higher ferritin levels. On multiple-variable analysis, being non-diabetic (p = 0.013) and alcoholic (p = 0.046) was significantly associated with high serum ferritin. No association was found with body mass index, tumour stage, size, macrovascular invasion, number of nodules, alpha-fetoprotein, bilirubin, international normalized ratio, and survival. CONCLUSION: In patients with nvHCC, serum ferritin levels are higher in non-diabetics and alcoholics.
