Long-term colchicine therapy of familial Mediterranean fever

Area of Science:

• Pediatric Rheumatology
• Genetics and Inherited Diseases
• Pharmacology

Background:

• Familial Mediterranean fever (FMF) is an autoinflammatory disorder causing recurrent fever and polyserositis.
• Continuous prophylactic colchicine is an established treatment for FMF in adults, effectively suppressing attacks.
• The efficacy and safety of colchicine in pediatric FMF patients require specific evaluation.

Purpose of the Study:

• To assess the effectiveness of prophylactic colchicine therapy in reducing FMF attacks in children.
• To evaluate the safety and tolerability of long-term colchicine use in a pediatric cohort.

Main Methods:

• A cohort of 30 children diagnosed with FMF was studied.
• Fourteen children were selected for colchicine therapy.
• Treatment adherence and clinical outcomes, including attack frequency and side effects, were monitored.

Main Results:

• Eight children who adhered to prophylactic colchicine therapy for a mean of 29 months showed a significant decrease in FMF attack frequency.
• Six children did not comply with the treatment regimen.
• No deleterious side effects were observed during the study period.

Conclusions:

• Prophylactic colchicine therapy appears effective in reducing FMF attacks in children.
• While no adverse effects were noted, the long-term safety of colchicine in childhood FMF management remains undetermined.
• Further research is warranted to establish definitive safety profiles for pediatric colchicine use.
