Objective: Hair loss generates severe psychosocial implications. To date, exploring the prognostic factors of possible clinical benefit of autologous blood concentrate platelet rich plasma (PRP) was failed. The aim of our pilot study was to explore the correlation between the individual inflammation genetic profile and PRP efficacy in the treatment of hair follicle regeneration. Patients and Methods: 41 volunteers (25 men, 16 women) took part in this retrospective study. All the patients were scheduled for 4 sessions of PRP application with intervals of 40-60 days. All the patients were checked up at 6 weekly intervals for 6 months and, then, at the end of the first year. A panel of 5 polymorphisms on 4 genes (IL-1α, IL-1β, IL-6, and IL-10) implicated in the individual genetic inflammation profile were performed. Results: A significant increase rate in hair density was noticed after the third month of treatment in 32/41 (78%) of the subjects. We found an interesting association between the pro-inflammatory cytokine IL-1á polymorphism C>A (rs17561) and responders to PRP treatment. The cases carrying C/C genotype (coding for Ser114) were 21 (66%) in responders and only 2 (22%) in non-responders (p<0.05). In addition, about IL-1α, the frequency of G/G genotype in responder patients was over two times lower in responder (31%) than in non-responder patients (78%). Conclusions: Our pilot study demonstrated a correlation between the individual genetic inflammatory profile and the efficacy of the PRP treatment in males. On the contrary, in females, it showed a negative correlation. IL-1α could be used as a prognostic value for PRP efficacy. Also, these results provide preliminary evidence that may encourage the design of controlled clinical trials to properly test this modus operandi on a large number of subjects.
