Brief Summary

Liver dysfunction marked by elevated alanine transaminase enzymes is quite common in dengue patients and subsequently affects the disease's severity and healing process. Unfortunately, liver function tests cannot always be done, especially in hospitals with limited facilities. In contrast, routine hematology tests are considered regular and inexpensive tests that can be performed on dengue patients. Therefore, this study aims to determine hematological parameters as markers of elevated liver enzymes in dengue patients.

Detailed Description

This cross-sectional study involves 11 dengue fever patients, consisting of 9 men and two women, at Sebelas Maret University Hospital (RS UNS), Sukoharjo. The study was conducted in May 2021. Inclusion criteria included patients who were hospitalised at UNS Hospital with the following criteria: (1) adult patients (19-65 years); (2) diagnosed with dengue hemorrhagic fever according to WHO 2011 criteria; (3) routine blood examination at least once in seven days since the onset of fever; and (4) checked alanine transaminase and aspartate transaminase levels at least once in seven days from the onset of fever. The research was approved by the Regional General Hospital Health Research Ethics Commission (RSUD) by Dr Moewardi Surakarta with the number 938/X/HREC/2021.

Dengue infection is classified according to WHO 2011 criteria, including dengue fever, dengue hemorrhagic fever, and dengue shock syndrome. Dengue fever has criteria in the form of acute fever with two or more other symptoms (headache, retroorbital pain, myalgia, arthralgia, rash, bleeding manifestations); laboratory investigations support dengue fever (platelets 150,000/mm3, leukocytes <5000/mm3, an increase in hematocrit 5-10%), with other confirmed assays (dengue virus isolation; fourfold increase in dengue-specific IgG or IgM serum; antigen or virus detection by immunohistochemistry, immunoassay, and ELISA; genome detection by RT-PCR). Dengue hemorrhagic fever has symptomatic criteria such as dengue fever plus signs and symptoms of plasma leakage (platelets 100,000/mm3, hematocrit increase 20%, pleural effusion, ascites, hypoproteinemia, or hypoalbuminemia). Meanwhile, dengue shock syndrome has symptomatic criteria such as dengue hemorrhagic fever plus symptoms of tachycardia and cold extremities.

Lymphocyte and HFLC examinations were carried out through a haematology analyser's routine blood tests. Meanwhile, liver function tests in aspartate transaminase and alanine transaminase were performed using ELISA. The range of normal cut-off values for each parameter is 11.7-16.2 mg/dL for hemoglobin, 35-45% for hematocrit, 3.9-5.3 x 106/mm3 for erythrocytes, 4.5-11 x 103/mm3 for leukocytes, 150-450 x 103 /mm3 for platelets, 0.8-5 x 103/mm3 for lymphocytes, 1-1.3 for NLR, and 0-1.4 for HFLC.

Data are presented using descriptive statistics and analysed using IBM SPSS (Statistical Package for the Social Sciences) Statistics 25 for Windows 10. Continuous variables are displayed using mean ± SD or median (IQR). Chi-Square tested the relationship between sex data categorical variables. The relationship between continuous variables of haematological parameter data and alanine transaminase status was tested using an unpaired t-test for normally distributed data, a Mann-Whitney test for data that were not normally distributed, and a correlation test in the form of simple logistic regression. The relationship between variables is significant if the p-value <0.05.
