Background: Alopecia areata (AA) is a chronic, non-scarring autoimmune condition characterized by unpredictable hair loss. It affects approximately 2% of the global population, impacting individuals of all ages and leading to significant psychological distress. Although various treatment modalities exist, their long-term efficacy and impact on quality of life remain inconsistent. Methotrexate, an immunosuppressant traditionally used in systemic form, has recently been formulated as a 1% topical gel to minimize side effects. This study aims to evaluate the efficacy of 1% methotrexate gel in patients with localized AA. Method: This prospective cross-sectional study was conducted at the Department of Dermatology, Venereology, and Leprosy, M.Y. Hospital, Indore, over a 12-month period. A total of 30 patients clinically diagnosed with localized AA were included. Participants applied 1% methotrexate gel twice daily on affected areas without using other topical or oral medications. The Severity of Alopecia Tool (SALT) was used to assess hair loss at baseline, 2, 4, and 6 weeks. Data were analyzed using SPSS software version 20, with paired t-tests to compare SALT scores. A p-value < 0.05 was considered statistically significant. Results: The study included 30 patients (66.7% male, 33.3% female) with a mean age of 27.53±9.78 years. The majority had scalp involvement (93.3%), and all participants had AA for less than six months. No change in the SALT score was observed at 2 weeks compared to baseline. However, statistically significant reductions were noted at 4 weeks (6.86% reduction, p=0.001) and 6 weeks (10.53% reduction, p=0.001). Physician Global Assessment revealed poor improvement in 61.9% of patients, good improvement in 37.2%, and very good improvement in 5.9%. Conclusion: Topical 1% methotrexate gel demonstrated moderate efficacy in treating localized AA, with significant improvement observed at 4 and 6 weeks. However, the majority of patients experienced only limited improvement. The findings suggest that topical methotrexate may be a viable option for localized AA, but its overall effectiveness is moderate compared to other treatments such as minoxidil. Further research with larger sample sizes and longer follow-up periods is needed to assess long-term efficacy and comparative effectiveness.
Alopecia areata (AA) is a prevalent, non-scarring, recurrent, chronic condition characterized by an unpredictable progression that can impact any area with hair. It encompasses various forms, including diffuse type, patchy type, total type affecting the entire scalp, and universalis affecting the entire body. AA is an autoimmune inflammatory disorder characterized by T lymphocyte-mediated targeting of hair follicles, however its pathophysiology remains incompletely elucidated [1]. AA can induce significant psychological suffering and diminish patients' confidence [2]. The paramount feature of management is to advise the patient regarding the unpredictable nature and progression of the ailment, as well as to address the obstacles associated with therapeutic modalities that exhibit fluctuating efficacy and undesirable effects [3,4]. AA impacts approximately 2% of the worldwide population, affecting individuals of all ages, though it is more common in youngsters. AA is characterized by its chronic nature, marked by repeated relapses, and the majority of therapy exhibit diminished efficacy upon discontinuation [6]. Typically, numerous therapy modalities have demonstrated efficacy in promoting hair growth in alopecia areata. The research about their long-term efficacy and effect on quality of life remains insufficient. Numerous specialists see intralesional corticosteroid therapy as the optimal treatment for localized scalp alopecia areata. Adverse consequences including injection discomfort, skin shrinkage, and telangiectasia. The relapse rate is 29% [7]. Topical Betamethasone dipropionate/valerate generally results in 75% hair regrowth, whereas telangiectasia, folliculitis, and atrophy may occur seldom. The relapse rate ranges from 37% to 63% [8]. Patients treated with minoxidil have demonstrated cosmetically satisfactory hair regrowth in 63.6% of instances. Topical minoxidil may cause undesirable effects such as contact dermatitis, face hypertrichosis, dryness, scaling, itching, and/or erythema [9]. The documented relapse rate ranges from 37% to 63%. Tretinoin promotes hair regrowth in roughly 58% of the participants examined, with side effects including skin irritation, dryness, erythema, desquamation, and burning sensations, as well as photosensitivity in some instances. It is not universally effective and is probably less efficacious than conventional treatments such as topical steroids [10]. Methotrexate (4-amino-N-methylpteroylglutamic acid) is a folic acid antagonist and an aminopterin derivative, approved as an antineoplastic agent in 1953 and for psoriasis treatment in 1971. As an immunosuppressant, Methotrexate is utilized in the management of various dermatological conditions, including psoriasis, bullous dermatoses, collagen storage disorders, vasculitides, neutrophilic dermatoses, and atopic dermatitis. Recently, oral doses of 15–25 mg weekly have been employed in the treatment of AA, yielding good outcomes [11]. Full hair regrowth was attained in 57% of instances. Adverse effects of oral methotrexate encompass chronic nausea, temporary increase of liver enzymes, and leucopenia [12]. To mitigate undesirable effects associated with oral methotrexate, topical methotrexate gel is currently being used for alopecia areata (AA) [13]. There is less data on definitive proof about the efficacy of topical methotrexate in alopecia areata.

After 6 weeks of treatment for Alopecia Areata, 61.9% of patients showed poor improvement, while 37.2% experienced good improvement. A small proportion (5.9%) demonstrated very good improvement, and no patients achieved an excellent outcome. Overall, the majority had limited improvement, highlighting the challenge of achieving high efficacy in this condition.
Alopecia Areata is a localized cutaneous inflammatory disorder traditionally managed with steroids and oral methotrexate. Recently, topical methotrexate has become available, expanding treatment options and potentially enhancing the effectiveness of managing localized Alopecia Areata. The alopecia areata group has the highest proportion of male patients, with 66.7% male and 33.3% female. In a study by Darwin E, Hirt PA et al with no difference in incidence between genders.[14]In the present study alopecia predominantly notable , with mean age of 31.57±7.07 present in early adulthood, in a study by Uzuncakmak TK The mean age was 29.86± 14.48 years in AA was observed [15]
In this study The mean duration of alopecia areata in the study was 4.99 ± 8.51 months. In a study by Lim SK et al on low dose MtX The mean disease duration was 29.03±32.61 months the discrpency in study may be due to few localized patches newly diagnosed were taken [16]
In present study Exclusively affects the scalp (93%), consistent with the condition's hallmark of localized hair loss and eyebrows (6%). In a similar study by Darwin et at frequency of involvement of scalp and eyebrow (66.8-95%), 3.8% repectively. 148
1.No Change at 2 Weeks: The mean SALT score remained unchanged at 11.68 ±
5.23 at 2 weeks, indicating that the intervention had not yet shown significant effects at this early time point.
2.Significant Improvement at 4 and 6 Weeks: At 4 weeks, the SALT score decreased to 10.88 ± 5.59, representing a 6.86% reduction from baseline, and at 6 weeks, it further decreased to 10.45 ± 5.39, reflecting a 10.53% reduction. Both reductions were statistically significant (p < 0.05), suggesting that the intervention started to show measurable benefits after 4 weeks and continued to improve at 6 weeks.In a study by Toma dm et al Comparative study between topical methotrexate 1% gel and minoxidil 5% gel in the treatment of localized alopecia areata clinically after 6 weeks, minoxidil showed significantly more excellent improvement than MTX (16% vs. 0%,) after 12 weeks, minoxidil and MTX showed excellent improvement (52 % and 36%) respectively.There was no significant difference in side effects (erythema and itching) between the MTX and minoxidil groups. Both topical MTX 1% gel and topical minoxidil 5% gel had high efficacy in treating localized AA, with no significant differences between them as evaluated by clinical and dermoscopic examination.[17]
This study evaluated the efficacy of topical methotrexate in patients with localized Alopecia Areata over a 6-week period. The findings revealed that the majority of patients were male (66.7%), with a mean age of 27.53±9.78 years. The condition predominantly affected the scalp (93.3%), and all participants had a disease duration of 6 months or less.The SALT score analysis demonstrated no change at 2 weeks but showed a statistically significant reduction at 4 weeks (6.86%) and 6 weeks (10.53%), indicating gradual improvement with continued use of topical methotrexate. Despite this, the Physician Global Assessment revealed that 61.9% of patients had poor improvement, while 37.2% experienced good improvement, and only 5.9% showed very good improvement. No patients achieved an excellent outcome.Compared to other studies, the improvement observed with topical methotrexate was moderate. For example, in a comparative study by Toma DM et al., minoxidil 5% gel showed superior results at 6 weeks. However, both methotrexate and minoxidil demonstrated high efficacy over a longer duration, suggesting that a prolonged treatment period might yield better results.In conclusion, topical methotrexate shows promise as a treatment option for localized Alopecia Areata, with significant improvement observed after 4 weeks. However, the overall effectiveness is moderate, and further studies with extended follow-up and larger sample sizes are warranted to better understand its long-term efficacy and comparative effectiveness against other treatments like minoxidil.
