Investigation of the relationship between alopecia areata and inflammatory blood parameters.

Aim: Alopecia areata (AA) is an inflammatory condition that causes regional shedding without scarring on the hair or eyebrows, eyelashes, and beard. In studies conducted, it has been concluded that platelet/lymphocyte ratio (PLR), neutrophil/lymphocyte ratio (NLR), and mean platelet volume (MPV) are significant indicators of systemic inflammation in various diseases. In the present study, our aim was to examine these parameters in AA patients and to investigate their relationship with the disease.
