The purpose of this study was to compare neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and mean platelet volume (MPV) values of patients with measles within the healthy control group and then determine the utility of these parameters for determination of inflammatory situation in patients with measles.A total of 51 pediatric patients who had visited Harran University Medical Faculty Pediatrics Clinic between June 2018 and May 2019 and who had been diagnosed with measles after anamnesis, clinical, and serological evaluations were included our study; 49 healthy children who visited our clinic for various reasons and had taken hemogram tests were also added to our study as the control group.NLR and PLR values were observed higher than the control group for patients diagnosed with measles; however, the difference between the two groups was not statistically significant (p values 0.515 and 0.796, respectively). When MPV values of patients diagnosed with measles and control groups were compared, it was determined that MPV value was statistically lower in patients diagnosed with measles (p: 0.001).Based on the parameters obtained through our study, it can be said that NLR and PLR are not suitable parameters for proving inflammation in patients with measles but MPV can be used as a convenient parameter for that purpose. However, prospective studies conducted with more patients are needed in this respect.
