Case Report: Repigmentation and complete hair regrowth in an 11-year-old preadolescent with alopecia totalis treated with a JAK inhibitor - Summary - MDSpire
To report a case of complete hair regeneration and repigmentation in a child with severe alopecia totalis following JAK inhibitor therapy.
Approach:
Patient Background: An 11-year-old girl with alopecia totalis for two years, initially treated with baricitinib and later switched to ritlecitinib.
Treatment Details: Baricitinib was administered for seven months, achieving SALT 65% with white and gray hair regrowth. Ritlecitinib was introduced at 50 mg/day, leading to black hair emergence at 6 weeks and complete regrowth at 6 months.
Key Findings:
Complete hair regrowth and repigmentation were achieved after 12 months of ritlecitinib therapy.
Family Dermatology Life Quality Index (FDLQI) improved from 18 to 4.
No significant adverse effects were reported during treatment.
Interpretation:
Limitations:
The findings are based on a single case study, limiting generalizability.
Current evidence on the relationship between treatment duration and repigmentation is largely limited to case reports.
Conclusion:
The case provides valuable real-world evidence for the phenomenon of hair repigmentation in pediatric alopecia areata following JAK inhibitor treatment.
A randomized clinical trial found that a team-based connected health model achieved equivalent improvements in atopic dermatitis severity and symptoms compared with conventional in-person care over 12 months.
