Abstract

Fibro Q and FIB-4 index are non-invasive biomarkers to evaluate liver fibrosis in chronic hepatitis. This study aimed to evaluate and compare the diagnostic accuracies of Fibro Q and FIB-4 index compared with fibroscan in chronic B hepatitis. This research was a cross-sectional study including 145 patients with chronic B hepatitis who had a fibroscan examination at the Dr.Wahidin Sudirohusodo Hospital during July 2014-June 2016. The clinical data included sex, age, Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), platelet, Prothrombin Time (PT)/International Normalized Ratio (INR). Fibro Q and FIB-4 index were compared with fibroscan to predict various fibrotic degrees of chronic B hepatitis patients. There were significant differences compared to fibroscan, the highest Fibro Q average was found in the medium degree of fibrosis and the lowest in the normal fibroscan (p<0.01) while the highest FIB-4 average was found in the high degree of fibrosis and the lowest in the normal fibroscan (p<0.001). Fibro Q sensitivity and specificity test against fibroscan have AUC value of 0.579 by using a 9.33 cut-off with a sensitivity of 80.5% and specificity of 28.1%, while FIB-4 has AUC value of 0.723  by using cut-off 14.31 with sensitivity 80.5% and specificity 46.9%. These results show that both Fibro Q and FIB-4 index can be used to assess liver cirrhosis as well as fibroscan. FIB-4 Index has a better diagnostic value compared to Fibro Q, so this marker can be used as a simple screening instrument.

Abstract

This literature aims to review various aspects of HbA1c as a Diabetes Mellitus (DM) biomarker and various HbA1c examination methods and their respective advantages and limitations. Diabetes mellitus is a condition characterized by chronic hyperglycemia and can lead to microvascular and macrovascular complications in the future. HbA1c has been used extensively over the last few decades to monitor glycemic control and assess microvascular and macrovascular risk. It has also been used as one of the diagnostic criteria for DM. HbA1c is hemoglobin A, which is glycated at the N terminal of its valine beta-globin chain and provides an overview of glycemic control over the past three months. HbA1c is often reported using % or mmol/mol units and can be adjusted to assess the average blood glucose level over the past three months. Various methods developed for HbA1c examination include immunoassay, boronate affinity, enzymatic, capillary electrophoresis, and Ion-Exchange High-Performance Liquid Chromatography (IE-HPLC), and each has its advantages and limitations. In addition to their advantages in detecting HbA1c, the capillary electrophoresis and IE-HPLC methods can also detect other types of hemoglobin and the presence of hemoglobin variants.
