Azathioprine in combination with methotrexate: a therapeutic alternative in severe and recalcitrant forms of alopecia areata?

II Consensus of the Brazilian Society of Dermatology for the treatment of alopecia areata

BACKGROUND

Alopecia areata is a highly frequent disease with great variability in clinical presentation, severity, and prognosis. It has a significant negative impact on quality of life, especially in the moderate and severe forms.

OBJECTIVE

To disseminate guidelines, prepared by a group of Brazilian experts, for the treatment and follow-up of patients with alopecia areata.

METHODS

Eight specialists from different university centers with experience in alopecia areata were appointed by the Brazilian Society of Dermatology to reach a consensus on its treatment. Using the adapted DELPHI methodology, relevant elements were considered and then an analysis of the recent literature was carried out and the text produced. Consensus on the guidelines was defined with the approval of at least 70% of the panel of experts.

RESULTS/CONCLUSIONS

Treatments vary according to patient age and disease severity. Intralesional injectable corticosteroid therapy was considered the first option for localized disease in adults. In severe cases, Janus Kinase inhibitors are the treatment with the highest level of evidence. Systemic corticosteroid therapy and immunosuppressants (corticosteroid-sparing agents) are also options in these cases. Contact immunotherapy (diphencyprone) is an alternative for stable extensive cases. The assessment of side effects is as important as the hair regrowth rate.

Guidelines for the Management of Patients with Alopecia Areata in Korea: Part II Systemic Treatment

BACKGROUND

Alopecia areata (AA) is a chronic disease with an unpredictable course and can have a severe psychological impact on an individual.

OBJECTIVE

To provide evidence and consensus-based statements regarding the treatment of patients with AA in Korea.

METHODS

We searched for relevant studies from inception to May 2021 regarding the systemic treatment of AA. Evidence-based recommendations were also prepared. The evidence for each statement was graded and classified according to the strength of the recommendations. Hair experts from the Korean Hair Research Society (KHRS) voted on the statement, and an agreement of 75% or greater was considered as having reached consensus.

RESULTS

Current evidence supports the efficacy of systemic corticosteroids, oral cyclosporine monotherapy or combination with systemic corticosteroids, and oral Janus kinase inhibitors in severe AA patients. Systemic steroids may be considered for pediatric patients with severe AA. A consensus was achieved in three out of nine (33.3%), and one out of three (33.3%) statements pertaining to systemic treatment in adult and pediatric AA, respectively.

CONCLUSION

The present study produced up-to-date, evidence-based treatment guidelines for AA associated with the consensus obtained by experts based on the Korean healthcare system.

Treatment of pediatric alopecia areata: A systematic review

Background:

Alopecia areata (AA) is an autoimmune, nonscarring hair loss disorder with slightly greater prevalence in children than adults. Various treatment modalities exist; however, their evidence in pediatric AA patients is lacking.

Objective:

To evaluate the evidence of current treatment modalities for pediatric AA.

Methods:

We conducted a systematic review on the PubMed database in October 2019 for all published articles involving patients <18 years old. Articles discussing AA treatment in pediatric patients were included, as were articles discussing both pediatric and adult patients, if data on individual pediatric patients were available.

Results:

Inclusion criteria were met by 122 total reports discussing 1032 patients. Reports consisted of 2 randomized controlled trials, 4 prospective comparative cohorts, 83 case series, 2 case-control studies, and 31 case reports. Included articles assessed the use of aloe, apremilast, anthralin, anti-interferon gamma antibodies, botulinum toxin, corticosteroids, contact immunotherapies, cryotherapy, hydroxychloroquine, hypnotherapy, imiquimod, Janus kinase inhibitors, laser and light therapy, methotrexate, minoxidil, phototherapy, psychotherapy, prostaglandin analogs, sulfasalazine, topical calcineurin inhibitors, topical nitrogen mustard, and ustekinumab.

Limitations:

English-only articles with full texts were used. Manuscripts with adult and pediatric data were only incorporated if individual-level data for pediatric patients were provided. No meta-analysis was performed.

Conclusion:

Topical corticosteroids are the preferred first-line treatment for pediatric AA, as they hold the highest level of evidence, followed by contact immunotherapy. More clinical trials and comparative studies are needed to further guide management of pediatric AA and to promote the potential use of pre-existing, low-cost, and novel therapies, including Janus kinase inhibitors.

Consensus on the treatment of alopecia areata - Brazilian Society of Dermatology

BACKGROUND

Alopecia areata is a highly frequent disease with an impact on quality of life and several treatment options with little clinical confirmatory evidence.

OBJECTIVE

To disseminate the recommendations of Brazilian dermatologists with expertise in the treatment of alopecia areata.

METHODS

Eight specialists with expertise in alopecia areata from different university centers were appointed by the Brazilian Society of Dermatology to reach a consensus on its treatment. Based on the adapted DELPHI methodology, the relevant elements were considered; then, an analysis of recent literature was carried out and the consensus was written down. Consensus on the management of alopecia areata was defined with the approval of at least 70% of the panel.

RESULTS/CONCLUSIONS

Intralesional injectable corticotherapy was considered the first option for localized disease in adults. In extensive cases with signs of activity, systemic corticosteroid therapy should be considered and can be used together with immunosuppressants (corticosteroid-sparing agents). The use of an immunosensitizer (diphencyprone) is an option for stable long-term cases. Evaluation of side effects is as important as the rate of hair regrowth.
