OBJECTIVES: The exact mechanism of partial clinical remission in type 1 diabetes mellitus (T1DM) has not been elucidated yet. The severity of the inflammation at the time of diagnosis may affect the occurrence or duration of this phase. We aimed to investigate the relationship between hematological inflammatory parameters at the time of diagnosis in T1DM and (i) daily insulin requirement during the follow-up and (ii) the presence of partial clinical remission period, which was determined according to insulin dose-adjusted HbA1c levels.
METHODS: A single-center retrospective study was conducted, including children who were diagnosed with T1DM, were positive for at least one autoantibody, and were followed up for one year in our clinic between 2010 and 2020.
RESULTS: Sixty-eight patients (55.9% female, 64.7% prepubertal) were included in the study, whose mean age was 8.4 ± 4.2 years. A total of 38 patients (55.9%) had partial clinical remission. None of the initial hematological indices were associated with the occurrence of partial remission. Initial neutrophil/lymphocyte ratio (NLR) and derived-NLR (d-NLR) levels were significantly lower (p=0.011 and 0.033, respectively) and lymphocyte/monocyte ratio (LMR) levels were significantly higher (p=0.005) in patients who showed an insulin requirement of <0.5 IU/kg/day at the 3rd month after diagnosis.
CONCLUSIONS: Initial hematological parameters were not found as a predictor of partial clinical remission period in T1DM in children. However, a lower NLR and d-NLR, or a higher LMR at the time of diagnosis can be used as an indicator of a low daily insulin need at the 3rd month of T1DM.
