ABSTRACT
Background: Hepatitis C is a leading cause of liver fibrosis, cirrhosis, and cirrhosis associated complications. In this study, we compared readily available non-invasive fibrosis indexes with fibro scans for fibrosis staging and predicting its progression in Pakistani population. Methods: The retro prospective cross-sectional study was conducted in medicine unit 1 and 2 and hepatitis clinic of Lahore General Hospital, Lahore starting from February 12, 2018 to January 8, 2019. We studied 1464 HCV infected patients which were got CBC, LFTs, ELISA, PCR and fibro scan was done to perfectly diagnose ongoing hepatitis C infection. In order to differentiate HCV fibrosis progression, we compared the effectiveness of readily available AST to Platelet Index (APRI), and FIB-4 with fibro scan. Results: Readily available serum indexes AST to Platelet Index (APRI) and FIB-4 were able to stage liver fibrosis in advanced stages of fibrosis (F4 especially) with correlation coefficient indexes 0.462, and 0.131 with considerable specificities and sensitivities. For APRI >1.5, it did predict F4 stage with sensitivity of 87.6% and specificity of 74.8%. For Fib-4> 3.25, it did predict F4 stage with sensitivity of 72.3% and specificity of 53.2%. Conclusion: Readily available and cheap serum indexes, AST to Platelet Index (APRI) and FIB-4 accurately predicted distinguished between cirrhotic and non- cirrhotic stages in HCV infected patients in comparison to the costly and rarely available Fibro scan score.
ABSTRACT
Background: Non‐alcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver injury. The most important predictor of mortality in NAFLD is the extent of liver fibrosis. Advanced liver fibrosis is associated with overall and liver related mortality. The upcoming non-invasive imaging modality for the evaluation of liver fibrosis is transient elastography (TE) (Fibro scan®). The aim of this study is to assess hepatopathy among diabetics using TE and to correlate the degree of hepatopathy with the associated risk factors.Methods: Type 2 diabetes mellitus patients were assessed for liver stiffness using TE. Liver stiffness was correlated with the associated risk factors. Authors recruited 100 patients from diabetic clinic in tertiary care teaching hospital.Results: About 55% of males and 39% of females had increased liver stiffness. 14% of males and 11% of females had severe fibrosis(F3-F4). Body mass index, waist circumference, fasting blood sugar levels, and liver enzymes, had significant positive correlation with liver stiffness whereas triglyceride levels, high-density lipoprotein levels, and duration of diabetes mellitus did not correlate with liver stiffness.Conclusions: Diabetic patients have high prevalence of NAFLD and advanced fibrosis. Those with obesity and dyslipidaemia are at particularly high risk. Type 2 diabetes mellitus patients with hepatopathy can be easily identified using TE scan eliminating the need for liver biopsy. The establishment of a national program for the recognition of NAFLD is essential to reduce the risk of liver disease progression.
ABSTRACT
Objective To explore the application value of the liver stiffness measurement (LSM) on complications after hepatectomy.Methods The retrospective case-control study was conducted.The clinical data of 121 hepatocellular carcinoma (HCC) patients who underwent hepatectomy in the Mianyang Central Hospital from January 2011 to April 2017 were collected.All 121 patients received LSM using Fibro Scan,and 81 undergoing laparoscopic liver resection (LR) and 40 undergoing open liver resection (OR) were respectively allocated into the LR and OR groups.Observation indicators:(1) comparisons of intra-and post-operative situations;(2) risk factors analysis affecting postoperative complication of HCC patients;(3) area under the curve (AUC) of LSM and postoperative complications;(4) comparisons of intra-and post-operative situations,when LSM ≤17.5 kPa;(5) comparisons of intra-and post-operative situations,when LSM ＞ 17.5 kPa;(6)comparisons of intra-and post-operative situations between patients with LSM ≤ 17.5 kPa and LSM ＞ 17.5 kPa in the LR group.Measurement data were represented as x±s,and mean comparisons between groups were done using the t test.Comparisons of count data and univariate analysis were analyzed using the chi-square test and Fisher exact probability.The multivariate analysis was done using the logistic regression model,using P＜0.01 as a inclusion criteria in the univariate analysis.The critical value of postoperative complication was calculated using the receiver operating characteristic curve (ROC).Results (1) Comparisons of intra-and post-operative situations:all the 121 patients underwent successful surgery,including 4 with conversion to open surgery in the LR group.Cases with Pringle manner were 51 in the LR group and 17 in the OR group,with a statistically significant difference (x2 =4.555,P＜0.05).Operation time,volume of intraoperative blood loss,case with intraoperative blood transfusion,Ishak score of 1-3 and 4-6 scores,postoperative complications and duration of hospital stay were respectively (248±78)minutes,(292±229)mL,14,14,67,29,(12±7)days in the LR group and (221±78)minutes,(281± 194)mL,9,9,31,10,(13±6)days in the OR group,with no statistically significant difference between groups (t =1.843,0.282,x2 =0.473,0.473,1.431,t =0.075,P＞0.05).(2) Risk factors analysis affecting postoperative complication of HCC patients:39 of 121 patients had postoperative complications.Results of univariate analysis showed that retention 15-minute rate of indocyanine green (ICG R15),LSM,volume of intraoperative blood loss and Ishak score were risk factors affecting postoperative complication of HCC patients (x2 =7.161,32.490,7.725,2.863,P＜0.l).Results of multivariate analysis showed that LSM ＞ 15.0 kPa was an independent risk factor affecting postoperative complication of HCC patients [odds ratio (OR) =6.906,95％ confidence interval (CI):2.307-20.672,P＜0.05].(3) AUC of LSM and postoperative complication:when LSM of postoperative complication ＞ 17.5 kPa,sensitivity,specificity and AUC were respectively 64.1％,85.4％ and 0.749 (95％CI:0.662-0.824,P＜0.05).(4) Comparisons of intra-and post-operative situations,when LSM ≤ 17.5 kPa:duration of hospital stay was respectively (10±5) days in the LR group and (13±7) days in the OR group,with a statistically significant difference between groups (t--2.389,P＜0.05).(5) Comparisons of intra-and post-operative situations,when LSM ＞ 17.5 kPa:operation time,volume of intraoperative blood loss,cases with postoperative complications and hepatic dysfunction were respectively (277±76)minutes,(505±232)mL,21,17 in the LR group and (212-± 109) minutes,(328±250) mL,4,2 in the OR group,with statistically significant differences between groups (t=2.060,2.057,P＜0.05).(6) Comparisons of intra-and post-operative situations between patients with LSM ≤ 17.5 kPa and LSM ＞ 17.5 kPa in the LR group:operation time,volume of intraoperative blood loss,cases with postoperative complications and hepatic dysfunction and duration of hospital stay were respectively (236±76)minutes,(197± 153)mL,8,3,(10±5)days in the LR group and (277± 76)minutes,(505±232) mL,21,17,(16±9)days in the OR group,with statistically significant differences between groups (t=0.657,3.398,x2 =36.547,36.475,t=17.414,P＜0.05).Conclusion LSM is an independent risk factor affecting postoperative compfications after hepatectomy,when LSM ＞ 17.5 kPa,LR is associated with higher incidence of postoperative complications compared with OR.
