fibrin and Alopecia

The role of enriched autologous plasmas in androgenetic alopecia (AGA) management is emerging in recent literature.. In this prospective study, the authors aimed to confirm that the induction of a minor local trauma immediately followed by injections of an enriched plasma made of a strongly concentrated platelet fraction, a robust white cell presence, concentrated fibrinogen, and other plasma proteins (injectable leukocyte platelet-rich fibrin [iL-PRF]) could be able to produce positive clinical results in patients with AGA.. A 2-injection regimen was instituted, with a 3-month interval between the 2 interventions. A treatment group (TG) and a control group (CG) were instituted. Macrophotographs were taken at baseline and after 6 months, and rated by 5-people expert panel (blinded to this assignment) using the 15-point scale proposed by Jaeschke to evaluate the clinical change.. Overall, TG showed better scores compared with the CG in all 5 classes of global physician assessment at baseline, all age groups, and in both sexes, and such differences always reached statistical significance. A greater severity at baseline showed a larger improvement after treatment in the TG.. This study provides preliminary evidence that the biological composition of the iL-PRF is of crucial importance in ensuring a good degree of clinical efficacy in patients with AGA.

The objective of this study was to determine the effect of platelet-rich fibrin matrix (PRFM) treatment on androgenetic alopecia. Prospective cohort study of 15 (9 male and 6 female) subjects with androgenetic alopecia for at least 1 year who were treated with intradermal injections of autologous PRFM three times on a monthly basis. Hair density indices were measured in triplicate in the same area of the scalp before the treatment and 1, 2, 3 and 6 months after initial treatment. Hair density index (HDI) measurements were obtained and compared with pretreatment values for each subject. After a series of three intradermal PRFM injections, hair density indices increased significantly at 2 (47.4 ± 22.7%, p = 0.0031) and 3 (106.4 ± 56.9%, p = 0.0277, paired t-test) months after the initial treatment, and approached statistical significance at 6 months (75.1 ± 46.82%, p = 0.0606) after the initial treatment. Patients who achieved greater than 25% increase in HDI by 2 months after the initial treatment were more likely to have greater than 25% improvement at 6 months after the initial treatment (100 vs. 16.7%, p = 0.0476). Androgenetic alopecia affects a significant number of both men and women. A series of intradermal injections of autologous PRFM increased the HDI in patients with androgenetic alopecia at 2 and 3 months after initial treatment; this improvement approached statistical significance at 6 months after initiating treatment. Autologous PRFM injections may be a valuable treatment for androgenetic alopecia, particularly in cases with mild hair loss. The level of evidence is level 2.

We have studied 10 cases of scarring alopecia, and investigated the diagnostic reliability of immunofluorescence and histopathology in lichen planopilaris and pseudopelade. In the light of our findings, we discuss the possible pathomechanisms of both disease processes.
