    Identification of type 2 diabetes patients with non-alcoholic fatty liver disease who are at increased risk of significant hepatic fibrosis: a cross-sectional study
    (Sri Lanka Medical Association, 2023) Mettananda, K.C.D.; Egodage, T.; Dantanarayana, C.; Solangarachchi, M.B.; Fernando, R.; Ranaweera, L.; Siriwardhena, S.; Ranawaka, C.K.; Kottahachchi, D.; Pathmeswaran, A.; Dassanayake, A.S.; de Silva, H.J.
    INTRODUCTION: Annual screening of patients with diabetes for fatty liver, and identifying those with significant hepatic fibrosis using the FIB-4 score and vibration-controlled transient elastography (VCTE) has been recommended to detect patients who may progress to advanced hepatic fibrosis/cirrhosis. However, VCTE is not freely available in resource-limited settings. OBJECTIVES: To identify clinical and biochemical predictors of significant liver fibrosis in diabetics with fatty liver. METHODS: We conducted a cross-sectional study among all consenting adults with T2DM and non-alcoholic fatty liver disease (NAFLD) attending the Colombo North Teaching Hospital, Ragama, Sri Lanka from November 2021 to November 2022. FIB-4 scores were calculated and patients with a score ≥1.3 underwent VCTE. Risk associations for liver fibrosis were identified by comparing patients with significant fibrosis (LSM ≥8 kPa) with those without significant fibrosis (FIB-4<1.3). RESULTS: A total of 363 persons were investigated. Of these, 243 had a score of FIB-4 <1.3. Of the 120 with a FIB-4 ≥1.3, 76 had LSM ≥8 kPa. Significant fibrosis was individually associated with age (OR 1.01, p<0.0001), duration of diabetes (OR 1.02, p=0.006), family history of liver disease (OR 1.42, p=0.035), waist (OR 1.04, p=0.035), and FIB-4 (OR 2.08, p<0.0001). However, on adjusted analysis, significant fibrosis was only associated with a family history of liver disease (OR 2.69, p=0.044) and FIB-4 (OR 1.43, p<0.001). CONCLUSION: In patients with T2DM and fatty liver, advancing age, increased duration of diabetes, a family history of liver disease, waist circumference and a high FIB-4 score increase the risk of significant hepatic fibrosis. Targeted interventions in this group may help prevent progression to advanced hepatic fibrosis/cirrhosis.

    Is splenic stiffness measurement(SSM) better than Baveno VII criteria to predict oesophageal and cardio- fundal varices in patients with compensated advanced liver cell disease (cACLD)?
    (Sri Lanka Medical Association, 2023) de Silva, A.P.; Niriella, M.A.; Nishad, A.A.N.; Samarawickrama, V.T.; Jayasundara, H.; Ranawaka, C.K.; de Silva, S.T.; Withanage, M.; Ediriweera, D.; de Silva, H.J.
    INTRODUCTION: Liver and splenic stiffness measurements (LSM and SSM) using transient elastography (TE) are being increasingly used as a screening tool to predict varices. OBJECTIVES: We aimed to test the utility of Baveno-VII criteria (LSM>25kPa, LSM>20kPa with platelet count <130,000 and LSM>15kPa with platelet count <110,000) and SSM to predict oesophageal and cardio-fundal varices in a cohort of Sri Lankan patients with aALCD. METHODS: Consecutive patients with newly diagnosed Child’s class A cALCD (non-viral, BMI<30) were recruited prospectively. They underwent upper gastrointestinal endoscopy by an endoscopist followed by a Fibroscan by an operator who is unaware of endoscopy findings using ECHOSENS-Fibroscan-502 to measure LSM and SSM. Validity measurements of three Baveno-VII criteria and SSM values to predict oesophageal and cardio-fundal varices were calculated. RESULTS: One hundred and seventy-four individuals were recruited [Mean (95%CI) age 61.4 (59.7-62.8) years, 110 males], and 106 had varices. Our results indicate that the three Baveno VII criteria had sensitivities of 61%, 63% and 42%, and specificities of 79%, 77% and 87%. SSM>30kPa alone or in combination with LSM>15kPa had sensitivity of 81&75%, specificity of 72&83%, PPV of 82&87%, NPV of 71&67% and accuracy of 78&78% consecutively to predict oesophageal and cardio-fundal varices. CONCLUSION: Baveno VII criteria had low sensitivity but high specificity to predict oesophageal and cardio-fundal varices. SSM>30kPa alone or in combination with LSM>15kPa seemed to predict oesophageal and cardio-fundal varices better.
