Factors affecting post-embolization fever and liver failure after trans-arterial chemo-embolization in a cohort without background infective hepatitis- a prospective analysis.

BACKGROUND: Transarterial-chemo-embolization (TACE) is used for palliation of unresectable hepatocellular carcinoma (HCC). We studied the tolerability of TACE in a cohort of patients with NASH and alcoholic cirrhosis related HCC. METHODS: Of 290 patients with HCC (July 2011 - December 2014), 84 underwent TACE. They were monitored for post-TACE complications: postembolization fever (PEF), nausea and vomiting (NV), abdominal pain, infection, acute hepatic decompensation (AHD) and acute kidney injury (AKI). RESULTS: 84 patients [90.5% males, 89.2% cirrhotics, 89.2% nodular HCC, median age 63 (34-84) years] underwent 111 TACE sessions. All were Child class A [69.4% sessions (n = 77)] or B; ascites and portal vein invasion was present in 18 (16.2%) and 15 (13.6%), respectively. 42 (38.2%) TACE procedures resulted in complications [PEF 28 (25.2%), NV 4 (3.6%), abdominal pain 9 (8.1%), infection 7 (6.3 %), AHD 13 (11.7%), AKI 3 (2.7 %)]. There were no immediate post-TACE deaths. On univariate analysis elevated serum bilirubin (p = 0.046) and low serum albumin (p = 0.035) predicted PEF while low serum albumin (p = 0.021) and low platelet counts (p = 0.041) predicted AHD. In the multivariate model, factors with p < 0.200 on univariate analysis and factors derived from the previous literature were considered covariates. Female gender (p = 0.029, OR = 1.412), ascites (p = 0.030, OR = 1.212), elevated serum bilirubin (p = 0.007, OR = 4.357) and large tumour size (p = 0.036, OR = 3.603) were independent risk factors for PEF. Tumour diameter >5 cm (p = 0.049, OR = 2.410) and elevated serum bilirubin (p = 0.036, OR = 1.517) predicted AHD. CONCLUSION: In NASH and alcoholic cirrhosis related HCC patients pre-procedure serum bilirubin, ascites, tumour size and female gender predicted PEF post-TACE. Tumours larger 5 cm with elevated bilirubin predicted AHD post-TACE.

Identification of patients with type 2 diabetes with non-alcoholic fatty liver disease who are at increased risk of progressing to advanced fibrosis: a cross-sectional study.

INTRODUCTION: Identification of advanced hepatic fibrosis in non-alcoholic fatty liver disease (NAFLD) is important as this may progress to cirrhosis and hepatocellular carcinoma. The risk of hepatic fibrosis is especially high among patients with diabetes with NAFLD. Annual screening of patients with diabetes for fatty liver and calculation of Fibrosis-4 (FIB-4) score and exclusion of significant fibrosis with vibration-controlled transient elastography (VCTE) have been recommended. However, VCTE is expensive and may not be freely available in resource-limited settings. We aim to identify predictors of significant liver fibrosis who are at increased risk of progression to advanced liver fibrosis and to develop a prediction model to prioritise referral of patients with diabetes and NAFLD for VCTE. METHODS AND ANALYSIS: This cross-sectional study is conducted among all consenting adults with type 2 diabetes mellitus with NAFLD at the Colombo North Teaching Hospital, Ragama, Sri Lanka. All patients get the FIB-4 score calculated. Those with FIB-4 ≥1.3 undergo VCTE (with FibroScan by Echosens). Risk associations for progression to advanced liver fibrosis/cirrhosis will be identified by comparing patients with significant fibrosis (liver stiffness measure (LSM) ≥8 kPa) and without significant fibrosis (LSM <8 kPa). A model to predict significant liver fibrosis will be developed using logistic regression. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Ethics Committee of the Faculty of Medicine, University of Kelaniya (P/66/07/2021). Results of the study will be disseminated as scientific publications in reputable journals.

Subclinical mucosal inflammation in diarrhea-predominant irritable bowel syndrome (IBS) in a tropical setting.

BACKGROUND AND AIMS: There is evidence for low-grade inflammation in the pathophysiology of post-infectious irritable bowel syndrome (IBS). We assessed the degree of subclinical intestinal mucosal inflammation in diarrhea-predominant IBS (IBS-D) in a tropical setting. MATERIAL AND METHODS: In a prospective study over 1 year, we investigated 49 patients with IBS-D (cases; median age 34 years (range 18-59); M:F 36:13), diagnosed on Rome III criteria. 14 individuals with a family history of colon cancer (median age 46.5 years (range 23-56); M:F 6:8) were selected as controls. Stools of cases and controls were tested for calprotectin. During colonoileoscopy, serial biopsies were obtained. Mucosal mast cells, neutrophils, eosinophils and lymphocytes/plasma cell infiltrate were quantified. Tissue expression of IL-8 and IL-10 was assessed in biopsies by semi-quantitative RT-PCR. RESULTS: A history suggestive of an episode of infectious diarrhea (ID) was present in 16/49 cases and 0/14 controls (p = 0.013). In cases, there were significantly more mucosal mast cells in the ileum and all segments of colon and significantly more eosinophils in the cecum. Tissue expression of IL-8 was significantly higher and IL-10 significantly lower in cases compared with controls (target/standard cDNA ratio, median (range) IL-8: 1.25 (0.75-2) vs. 0.85 (0.63-1.3), p < 0.0001, Mann-Whitney U test; IL-10: 0.33 (0-0.63) vs. 0.55 (0.5-0.7), p < 0.0001). There was a significant inverse correlation between IL-8 and IL-10 expression (Pearson correlation, (-) 0.509; p < 0.01). CONCLUSION: There was evidence of subclinical intestinal mucosal inflammation in patients with IBS-D. The finding of increased eosinophils is novel, and may be of special relevance to IBS-D in the tropics.

Nonalcoholic Fatty Liver Disease in Diabetics: The Role of Hepatologist.

Diabetes mellitus is one of the most prevalent metabolic diseases worldwide, causing an enormous burden on the economies of both developed and developing nations. Nonalcoholic fatty liver disease (NAFLD) is very closely associated with diabetes, and the two diseases are known to cause an increase in morbidity and mortality. Timely referral of a diabetic with NAFLD to a hepatologist can definitely delay disease progression and the related complications. Despite the magnitude, there are no guidelines that recommend a screening algorithm that must be followed for evaluating NAFLD in at-risk diabetics at the primary care level and their further referral to hepatologists. Nonalcoholic fatty liver disease management needs heightened awareness among primary care physicians/endocrinologists and hepatologists, and a collaborative care approach is paramount in these patients. Certain antidiabetic drugs are found to be beneficial in the treatment of NAFLD patients with diabetes, however, none of them are FDA approved.

Patterns and predictors of mortality in a semi-urban population-based cohort in Sri Lanka: findings from the Ragama Health Study.

OBJECTIVE: To describe patterns and predictors of mortality in a semi-urban population in Sri Lanka. DESIGN: A prospective population-based cohort study. SETTING: Ragama Medical Officer of Health area in the Gampaha district, Sri Lanka. PARTICIPANTS: Adults between 35 and 64 years of age were recruited using an age stratified random sampling technique in 2007. MEASURES: At baseline, we recorded socio-demographic, lifestyle, anthropometric, biochemical and clinical data of the participants. Over 10 years, we obtained the cause and date of death from the death registration documents of deceased participants. We determined the survival probability of the cohort over 10 years and estimated Hazard ratios (HRs) for all-cause mortality (ACM), cardiovascular mortality (CVM) and cancer-related mortality (CRM) using Cox's proportional hazards model. We also estimated the survival probabilities for men and women in each 10-year age group and standardised mortality ratio relative to the source population. RESULTS: There were 169 deaths over 10 years with standardised mortality rates of 5.3 and 2.4 per 1000 years of follow-up for men and women, respectively. Independent predictors of: ACM were older age, lower income, smoking and diabetes mellitus while gender, education, occupation, harmful alcohol use, waist circumference and hypertension were not; CVM were older age, lower income, smoking, diabetes and hypertension while gender and harmful alcohol use were not; CRM was older age while gender, smoking and diabetes were not. Those engaged in clerical and technical occupations or unemployed had a lower risk of CRM as compared with those engaged in elementary occupations. CONCLUSIONS: Older age, lower income, smoking, diabetes and hypertension strongly predict mortality in this cohort. Addressing the identified modifiable predictors through behavioural modification will improve longevity in similar populations.

Sero-prevalence and vaccination status of hepatitis A and hepatitis B among adults with cirrhosis in Sri Lanka: a hospital based cohort study.

BACKGROUND: As acute viral hepatitis can be fatal in patients with cirrhosis, vaccination against hepatitis A (HAV) and hepatitis B (HBV) is recommended for non-immune patients. With increasing affluence the incidence of hepatitis A in childhood has decreased leading to a significant proportion of non-immune adults. As part of their routine investigation, hepatitis A IgG antibodies (anti-HAV IgG), hepatitis B surface antigen (HBsAg) and anti-HCV antibodies was checked and immunization status was assessed among consenting newly diagnosed cirrhotic patients presenting to a tertiary referral center. FINDINGS: Out of 135 patients, 107 [79.3%; males 91; mean age (SD) at presentation: 55.5 (11.6) years] with complete data were included for analysis. Most patients had either cryptogenic cirrhosis (62.6%) or alcoholic cirrhosis (29.9%); 2 (1.9%) had HBV cirrhosis, none had hepatitis C (HCV) cirrhosis. None of the patients had received vaccination against hepatitis A, while 71 (67.6%) had been vaccinated against HBV. The majority [62 (58%)] were negative for anti-HAV IgG. CONCLUSION: Most cirrhotic patients in this cohort were not immune to hepatitis A. None had been vaccinated against HAV, while a third of patients had not been vaccinated against HBV. Cirrhotic patients should be routinely investigated for immunity against HAV and HBV, and vaccination offered to those found to be non-immune.

Worsening cholestasis and possible cefuroxime-induced liver injury following "successful" therapeutic endoscopic retrograde cholangiopancreatography for a distal common bile duct stone: a case report.

BACKGROUND: Cefuroxime very rarely causes drug-induced liver injury. We present a case of a patient with paradoxical worsening of jaundice caused by cefuroxime-induced cholestasis following therapeutic endoscopic retrograde cholangiopancreatography for a distal common bile duct stone. CASE PRESENTATION: A 51-year-old, previously healthy Sri Lankan man presented to our hospital with obstructive jaundice caused by a distal common bile duct stone. Endoscopic retrograde cholangiopancreatography with stone extraction, common bile duct clearance, and stenting failed to improve the cholestasis, with paradoxical worsening of his jaundice. A liver biopsy revealed features of drug-induced intrahepatic cholestasis. Although his case was complicated by an episode of cholangitis, the patient made a complete recovery in 4 months with supportive treatment and withdrawal of the offending drug. CONCLUSIONS: This case highlights a very rare drug-induced liver injury caused by cefuroxime as well as our approach to treating a patient with paradoxical worsening of jaundice after therapeutic endoscopic retrograde cholangiopancreatography.

Recurrence of graft steatosis after liver transplantation for cryptogenic cirrhosis in recently commenced liver transplant program.

Non-alcoholic fatty liver disease (NAFLD) seems to recur in at least one third of patients transplanted for non-alcoholic steatohepatitis (NASH)-related cirrhosis. While, NASH recurrence does not seem to affect overall graft and patient survival up to 10 years, cardiovascular and infection-related morbidity and mortality seem to be increased in these patients. This report looks at the graft histology in patients who were transplanted for NASH-related cirrhosis after short-term follow up. We report a high prevalence of recurrent NAFLD in liver grafts post-transplant among five patients. The degree of steatosis noted among the recipients is alarming.

Usefulness of Routine Terminal Ileoscopy and Biopsy during Colonoscopy in a Tropical Setting: A Retrospective Record-Based Study.

Introduction. Available evidence for routine terminal ileoscopy during colonoscopy is equivocal. We investigated the place of routine terminal ileoscopy and biopsy during colonoscopy, in a tropical setting. Materials and Methods. All consenting adults undergoing colonoscopy had routine TI and biopsy. Patients with right iliac fossa (RIF) pain, diarrhoea, anaemia, suspected inflammatory bowel disease (IBD), and raised inflammatory markers were defined as Group A and all others undergoing colonoscopy as Group B. Results. Caecal intubation and TI were achieved in 988/1096 (90.15%) and 832/1096 (75.9%) cases, respectively. 764/832(91.8%) patients were included in final analysis. 81/764 (10.6%) patients had either macroscopic (34/81) or microscopic (47/81) abnormalities of terminal ileum; 20/81 had both. These were CD (28/47), tuberculosis (TB) (6/47), ileitis due to resolving infection (8/47), and drug-induced ileitis (5/47). 27/81 with macroscopically normal ileum had CD (18/27), ileitis due to resolving infection (5/27) and drug-induced ileitis (4/27) on histology. 12/764 (1.57%) patients with macroscopically normal colon had ileal CD (8/12), drug-induced ileitis (2/12), and resolving ileal infection (2/12) on histology. 47/764 (6.15%) patients had ileal pathology that influenced subsequent management. These were significantly higher in Group A (43/555 (8%)) than in Group B (4/209 (1.9%)) (P = 0.0048, χ (2) = 7.968). Conclusion. TI and biopsy improve diagnostic yield of colonoscopy in patients with RIF pain, diarrhoea, anaemia, suspected IBD, and raised inflammatory markers.

Gastric motility following ingestion of a solid meal in a cohort of adult asthmatics.

BACKGROUND/AIMS: Asthmatics have abnormal esophageal motility and increased prevalence of gastroesophageal reflux disease (GERD). The contribution of gastric motility is less studied. We studied gastric myoelectrical activity, gastric emptying (GE) and their association with GERD symptoms and vagal function in adult asthmatics. METHODS: Thirty mild, stable asthmatics and 30 healthy controls underwent real-time ultrasonography and 1 hour pre- and post-prandial cutaneous electrogastrography, following a test meal (480 kcal, 60% carbohydrate, 20% protein, 20% fat and 200 mL water). The percentage of normal slow waves and arrhythmias, dominant frequency and power, frequency of antral contractions, gastric emptying rate (GER) and antral motility index (MI) was calculated. Twenty-seven asthmatics underwent gastroscopy and in all subjects GERD symptoms were assessed by a validated questionnaire. Vagal function parameters were correlated with gastric motility parameters. RESULTS: The asthmatics (37% male; 34.8 ± 8.4 years) and controls (50% male; 30.9 ± 7.7 years) were comparable. None had endoscopic gastric pathological changes. Twenty asthmatics described GERD symptoms. Twenty-two (73.3%) asthmatics showed a hypervagal response. Compared to controls, asthmatics had delayed GER and lower MI, lower percentage of normal gastric slow waves, more gastric dysrythmias and failed to increase the post-prandial dominant power. There was no correlation of GE and cutaneous electrogastrography parameters with presence of GERD symptoms or with vagal function. CONCLUSIONS: Asthmatics showed abnormal gastric myoelectrical activity, delayed GE and antral hypomotility in response to a solid meal compared to controls. There was no association with vagal function or GERD symptom status.

Survival of patients with alcoholic and cryptogenic cirrhosis without liver transplantation: a single center retrospective study.

BACKGROUND: There is no recent data addressing the long term survival of cirrhosis patients without transplantation, but with the availability of optimal pharmacological and endoscopic therapies. We compared the long term transplant free survival of alcoholic (AC) and cryptogenic (CC) cirrhosis patients in a setting where liver transplantation was, until very recently, not available. AC and CC patient details were extracted from our database, maintained since 1995. For those who had not attended clinics within the past 4 weeks, the patient or families were contacted to obtain survival status. If deceased, cause of death was ascertained from death certificates and patient records. Survival was compared using Kaplan-Meier curves. RESULTS: Complete details were available in 549/651 (84.3%) patients (AC 306, CC 243). Mean follow up duration (SD) (months) was 29.9 (32.6). 82/96 deaths (85.4%) among AC and 80/94 deaths (85.1%) among CC were liver related. Multivariate analysis showed age at diagnosis and Child's class predicted overall survival among all groups. The median survival in Child's class B and C were 53.5 and 25.3 months respectively. Survival was similar among AC and CC. Among AC survival was improved by abstinence [HR = 0.63 (95% CI: 0.40-1.00)] and was worse with diabetes [HR=1.59 (95% CI: 1.02- 2.48)] irrespective of alcohol status. CONCLUSIONS: The overall survival of AC was similar to CC. Death in both groups were predominantly liver related, and was predicated by age at diagnosis and Child class. Among AC, presence of diabetes and non-abstinence from alcohol were independent predictors for poor survival.

Osteoporosis in adult Sri Lankan inflammatory bowel disease patients.

AIM: To determine if inflammatory bowel disease (IBD) is a risk factor for osteoporosis in adult Sri Lankans. METHODS: We identified eligible subjects from among consecutive patients diagnosed with IBD who attended our outpatient clinic. We included only patients aged between 20 and 70 years. Patients who were pregnant, had significant comorbidity, or were on calcium supplements or treatment for osteoporosis within the past 6 mo, were excluded. Healthy, age- and sex-matched controls were also recruited, in a control to patient ratio of 3:1. Both groups were screened for osteoporosis using peripheral dual energy X-ray absorptiometry scanning. RESULTS: The study population consisted of 111 IBD patients (male:female = 43:68; mean age 42.5 years) and 333 controls (male:female = 129:204; mean age 43.8 years). The occurrence of osteoporosis among IBD patients (13.5%) was significantly higher than among controls (4.5%) (P = 0.001). The frequency of osteoporosis was not significantly different between ulcerative colitis (14.45%) and Crohn's disease (10.7%). However, on multivariate analysis, only age (P = 0.001), menopause (P = 0.024) and use of systemic steroids (P < 0.001) were found to be associated independently with the occurrence of osteoporosis, while IBD, severity of disease, number of relapses, duration of illness or treatment other than systemic steroids were not. CONCLUSION: IBD does not appear to be an independent risk factor for the occurrence of osteoporosis in this population. However, the use of systemic steroids was a risk factor.
