Objective:
This study evaluated colchicine adherence in children and adolescents with familial Mediterranean fever (FMF) using the Medication Adherence Scale in FMF Patients (MASIF), and examined the influence of patient-related factors and family history.
Method:
A cross-sectional study was conducted among 324 paediatric FMF patients (1-18 years old). Colchicine adherence was measured via MASIF, and demographic, clinical, genetic, and socioeconomic variables were analysed.
Results:
Of 324 patients (mean age 11.8 ± 3.8 years), 88 (27.2%) showed good adherence and 236 (72.8%) poor adherence. Adherence was not significantly associated with sex, age group, age at diagnosis, disease severity, family history, colchicine intolerance/resistance, or biologic use. Erysipelas-like erythema was present in 28 patients (8.6%) at diagnosis and correlated with better adherence (p = 0.016). Of the 142 patients (43.8%) who self-reported regular colchicine use, MASIF indicated poor adherence in 101 (71.1%). School absenteeism was reported in 41 (46.6%) of the adherent group and 171 (72.5%) of the non-adherent group (p < 0.001).
Conclusion:
Colchicine non-adherence is frequent in paediatric FMF and largely unrelated to patient factors. Objective tools such as MASIF reveal higher non-adherence rates than self-reports and are essential for accurate evaluation in clinical decision making.
