Alopecia Areata
Conditions
Brief summary
Alopecia areata (AA) is a common autoimmune disease that targets hair follicles with a prevalence of approximately 0.1% and a lifetime incidence of approximately 1.7%. AA is the third most prevalent nonscarring hair loss disease. Pentoxifylline (PTX) is a non-selective inhibitor of phosphodiesterases, which moderates the intracellular levels of cyclic adenosine monophosphate and cyclic guanosine monophosphate by decreasing their hydrolysis and augmenting cyclic nucleotide-dependent signal transduction which leads to a wide spectrum of effects on the inflammation. PTX has anti inflammatory effects by inhibiting the pro-inflammatory cytokines (eg, IL-1, IL-6, and IL-8).Intralesional therapy has a number of advantages over topical therapy, including a faster and longer duration of action, penetration that is deeper than topical therapy, removal of the need for long-term topical medication, and improved patient compliance.The effect of microneedling for treatment of AA is supposed to stimulate the dermal papilla and stem cells by mechanical trauma and increasing the blood supply to the hair follicles.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| measuerement of improvement of alopecia areata patches by SALT score | 12 month | The clinical response will be evaluated based on the SALT score, the following percentages of scalp hair regrowth are possible: A0 = no change or further loss, A1 = 1%-24% regrowth, A2 = 25%-49% regrowth, A3 = 50%-74% regrowth, A4 = 75%-99% regrowth, and A5 = 100% regrowth. |
| measuerement of improvement of alopecia areata patches by Trichoscopic signs | 12 month | Trichoscopic examination each visit to evaluate the results and record signs of improvement of the disease including (short vellus hairs and terminal hairs) and disappearance of signs of activity(exclamation marks, blackdots) |
