Influencing factors of clinical efficacy of autologous platelet-rich plasma in the treatment of androgenetic alopecia
Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 12
Abstract
Objective To analyze the influencing factors of clinical efficacy of autologous platelet-rich plasma in the treatment of androgenetic alopecia. Methods From January, 2019 to December, 2021, 151 outpatients with androgenetic alopecia were treated in our hospital. All patients were treated with autologous PRP injection once a month and planned to received injection for 4-6 occasions. According to the hair growth before and after treatment, the treatment results were evaluated. The influencing factors in the treatment results were grouped and analyzed, including the treatment numbers (divided into 1-6 occasions), the grade of alopecia(three grades: mild, moderate and severe alopecia) and the Plt concentration in PRP[five grades(×109/L): extremely low concentration (<800), low concentration (801-1 000) and medium concentration (1 001-1 200), high concentration(1 201-1 500)and extremely high concentration(>1 501)]. Results The correlation coefficient between the number of treatments and the effective rate was pearson=0.986, P<0.001, showing a positive correlation. There was a statistical difference in the total number of treatments between groups (P<0.01). As to the severity of alopecia: The effective rates of mild and moderate alopecia patients (66.67%, 56.95%) were higher than those of severe alopecia patients (35%). The difference between groups was statistically significant (P<0.01). As to the concentration of Plt in PRP: The concentration of Plt directly affected the therapeutic effect. When the Plt count was (1 200-1 500)×109/L, the effect was optimal, reaching 68.12%, which was significantly higher than the other four groups(P<0.01). The treatment numbers, alopecia grade and Plt concentration in PRP were all related to the effectiveness of treatment (P<0.05). When the OR value of treatment numbers and Plt concentration was >1, the effective rate increased by 2.619 times and 2.033 times, respectively, as treatment numbers and Plt concentration increased. When the OR value of the grade of alopecia was 0.338 (0<0.338<1), the effective rate decreased with the increase of alopecia severity; For each grade increased, the effective rate would be compromised by 0.338. Conclusion When PRP is applied to treat AGA patients, the clinical therapeutic effect will be better in patients who received more treatments, PRP with higher Plt count, and be in the early degree of hair loss. Whether the higher the concentration of Plt in PRP, the better the therapeutic effect will be, remains to be further verified.
