Abstract
BACKGROUND/AIM: High-sensitivity C-reactive protein (hs-CRP) is used in the differential diagnosis of maturity-onset diabetes of the young (MODY)-3, but other inflammatory markers have not been investigated in MODY patients. We aimed to compare the serum levels of anti-inflammatory and proinflammatory cytokines between MODY patients and healthy subjects and show the inflammatory features in MODY subtypes. PATIENTS AND METHODS: Thirty patients with clinically suspected MODY and 34 healthy controls were included in this study. Next-generation sequencing (NGS) was used for the molecular diagnosis of MODY subtypes. Serum levels of cytokines were measured using a multiplexed cytokine assay and hs-CRP concentration was determined by the immunoturbidimetric assay. RESULTS: The hs-CRP levels were higher in both NGS-confirmed (MODY, n=17) (p=0.009) and NGS-unconfirmed (non-MODY, n=13) patients (p<0.001) than those in controls. However, IL-1β (p=0.001), IL-6 (p=0.018), IL-31 (p=0.003), TNF-α (p<0.001), and sCD40L (p=0.007) levels of MODY patients and IL-1β (p=0.002), IL-31 (p<0.001), IL-22 (p=0.018), and sCD40L (p=0.039) levels of non-MODY patients were lower than those of controls. While hs-CRP levels were lower in MODY3 patients than non-MODY3 patients (p=0.009), IL-17A (p=0.006) and IL-23 (p=0.016) levels for the first time in this study were found to be higher in patients with MODY3 than in patients with other MODY subtypes (p<0.05). CONCLUSION: MODY patients had lower serum levels of the proinflammatory cytokines IL-1β, IL-6, TNF-α, IL-31, and sCD40L compared to healthy controls. High IL-17A and IL-23 levels along with low hs-CRP levels may be potential markers to distinguish MODY3 from other MODY subtypes.
