Background
Autologous blood therapy (ABT) has been used to treat atopic dermatitis (AD) for over a century, even though evidence supporting its efficacy is lacking. We aimed to investigate the effectiveness and safety of autologous serum intramuscular injection (ASIM), which is a modified form of ABT, in treating mild-to-moderate AD.
Methods
This study was a 12-week, open-label, prospective, uncontrolled trial. Following a 4-week run-in period, 22 out of 25 screened patients received ASIM once a week for 4 weeks in conjunction with standard treatment. The primary outcome measure was the Eczema Area and Severity Index (EASI), while the secondary outcomes included the Scoring Atopic Dermatitis (SCORAD) score, Dermatologic Life Quality Index (DLQI), and patient ratings of pruritus, sleep difficulty, disease status, and treatment effectiveness. Safety parameters were also assessed.
Results
EASI scores showed a non-statistically significant trend toward improvement during ASIM intervention. Patients with at least a 50% improvement in the EASI score at 4 weeks were older and had lower peripheral eosinophil counts (p<0.05). Secondary endpoints, including the SCORAD score, pruritus, sleep difficulty, and DLQI, demonstrated statistically significant improvements at week 4 compared to baseline (p<0.05). No significant adverse reactions were observed.
Conclusions
This pioneering study suggests that repeated ASIM may improve the clinical symptoms of mild-to-moderate AD, particularly in terms of pruritus and overall quality of life. However, further research with a larger sample size is required to establish the clinical significance of these findings.
