Laboratory Parameters and Clinical Presentation of Children with Measles on Hospital Admission: Single-center Study from Sarajevo, Bosnia and Herzegovina.

Background: T Measles is a viral, highly contagious disease from the group of rash fevers, which mainly affects children. Persons suffering from measles are considered contagious four days before and four days during the period of the appearance of measles, which favors its faster spread. Clinical observation and laboratory diagnostics are essential for monitoring the course of the disease in order to prevent complications. Objective: Our study aimed to analyze the significance and usefulness of laboratory tests on admission to hospital in pediatric patients with measles. Methods: This prospective study included children with confirmed measles infection who came accompanied by parents to the Infectious Disease Clinic of the Clinical Center of the University of Sarajevo during nine months. Data on age, sex, symptoms and results of laboratory analyzes (biochemical, hematological and coagulation) were recorded. Results: The study included a total of 302 subjects, including 122 healthy controls and 180 measles patients. Significantly lower values observed for aPTT, absolute number of eosinophils and basophils, RBC, hemoglobin, hematocrit, MCV, MCH, MCHC in measles patients. Significantly higher values were observed for fibrinogen, D-dimer, WBC, neutrophils, lymphocytes, monocytes, RDW and MPV in measles patients in contrast to controls. Significantly higher values were also observed for serum chloride, glucose, CRP, AST, ALT and LDH values. AST/ALT, NLR, PLR, NPR, LMR, LCR, SII and AISI also showed significant differences in measles patients compared to controls. Conclusion: The results of our study showed that laboratory tests have great significance and potential in measles in pediatric patients admitted to the hospital. Lymphocyte/C-reactive protein ratio also showed good diagnostic potential.
