Severe alopecia areata treated with systemic corticosteroids

Treatment Options for Alopecia Areata in Children and Adolescents

Alopecia areata (AA) lifetime incidence is around 2%, with many patients first experiencing symptoms during childhood. However, ritlecitinib is the only FDA-approved treatment for pediatric patients 12 years and older. This review outlines reported topical, injectable, and oral treatment options for pediatric patients with AA. Clinical studies were obtained via a PubMed search using the following search terms: alopecia areata, areata, universalis, or totalis and medication, therapy, treatment, drug, or management. Only studies with pediatric patients were included in this review. Commonly used therapies, including corticosteroids, methotrexate, and minoxidil, newer promising medications, such as Janus kinase inhibitors, and less frequently used topical and systemic treatments are included. A summary of the drug development pipeline and ongoing interventional clinical trials with pediatric patients is provided. Treatments demonstrate variable efficacy, and many patients require combination therapy for maximal response. More robust clinical data is needed for many of the medications reviewed in order to provide better care for these patients.

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.

Childhood Alopecia Areata: An Overview of Treatment and Recent Patents

BACKGROUND

Alopecia Areata (AA) is a systemic autoimmune condition that usually starts in childhood.

OBJECTIVE

This article aims to review genetics, therapy, prognosis, and recent patents for AA.

METHODS

We used clinical queries and keywords "alopecia areata" AND "childhood" as a search engine. Patents were searched using the key term "alopecia areata" in Patents.google.com and freepatentsonline. com.

RESULTS

Due to an immune-mediated damage to the hair follicles, hair is lost from the scalp and other areas of the body temporarily or even permanently. Children with AA are generally healthy. Evidence of genetic association and increased predisposition for AA was found by studying families with affected members. Pathophysiologically, T- lymphocytes attack hair follicles and cause inflammation and destruction of the hair follicles and hair loss. In mild cases, there would be well-demarcated round patchy scalp hair loss. The pathognomonic "exclamation mark hairs" may be seen at the lesion periphery. In more severe cases, the hair loss may affect the whole scalp and even the whole body. The clinical course is also variable, which may range from transient episodes of recurrent patchy hair loss to an indolent gradually deteriorating severe hair loss. The treatment of AA depends on factors including patients' age, the extent of the hair loss, duration of disease, psychological impact, availability and side effect profile of the treatments. For localized patchy alopecia, topical application of corticosteroids and/or intralesional corticosteroids are the treatment of choice. Other topical treatments include minoxidil, anthralin, coal tar and immunotherapy. In severe resistant cases, systemic immunosuppressants may be considered. Although herbal medicine, acupuncture, complementary and alternative medicine may be tried on children in some Asian communities, the evidence to support these practices is lacking. To date, only a few recent patents exist in topical treatments, including Il-31, laser and herbal medications. Clinical efficacy is pending for these treatment modalities.

CONCLUSION

None of the established therapeutic options are curative. However, newer treatment modalities, including excimer laser, interleukin-31 antibodies and biologics, are evolving so that there may be significant advances in treatment in the near future. AA can be psychosocially devastating. It is important to assess the quality of life, degree of anxiety, social phobia and mood of the patients and their families. Psychological support is imperative for those who are adversely affected psychosocially.

Italian Guidelines in diagnosis and treatment of alopecia areata

Alopecia areata (AA) is an organ-specific autoimmune disorder that targets anagen phase hair follicles. The course is unpredictable and current available treatments have variable efficacy. Nowadays, there is relatively little evidence on treatment of AA from well-designed clinical trials. Moreover, none of the treatments or devices commonly used to treat AA are specifically approved by the Food and Drug Administration. The Italian Study Group for Cutaneous Annexial Disease of the Italian Society of dermatology proposes these Italian guidelines for diagnosis and treatment of Alopecia Areata deeming useful for the daily management of the disease. This article summarizes evidence-based treatment associated with expert-based recommendations.

[Treatment of alopecia areata with prednisone in a once-monthly oral pulse]

BACKGROUND

Various modalities have been used in the treatment of alopecia areata (AA), including pulsed oral corticosteroids. The aim of this study was to evaluate the efficacy and safety of pulsed oral prednisone in the management of AA.

METHODS

This was a prospective study in patients with progressive AA affecting more than 40% of the scalp. All patients received 5mg/kg (300 mg) oral prednisone once a month for 3 to 6 months and were examined for adverse effects. Hair growth was classified as complete, cosmetically acceptable, incomplete or no growth.

RESULTS

Thirty-four patients (18 men) with a mean age of 12+/-3 years were included. AA was ongoing for a mean 2 (1-17) years. Thirteen (38%) patients presented multifocal AA, six universalis (20%), six multifocal with ophiasic pattern (18%), six totalis (18%), and three ophiasic (6%). Six patients (18%) had no regrowth. At 3 months, incomplete or cosmetically acceptable response was noted in 28 patients (82%). At 6 months, 14 patients (41%) presented complete response, eight patients (23%) had a persistent incomplete response, and six patients (18%) had a persistent cosmetically acceptable response. Adverse effects were noted in five patients (15%). Variables predictive for no-growth response were nail involvement (P=0.001), associated dysimmunity (P=0.017), and universalis form (P=0.050).

CONCLUSION

A once-monthly oral pulse of 300 mg prednisone appears effective and safe. It can be recommended as first-line treatment for widespread AA.

Treatment of Severe Alopecia Areata: Combination Therapy Using Systemic Cyclosporine A with Low Dose Corticosteroids

BACKGROUND

Combination therapy using cyclosporine A (CsA) together with low-dose corticosteroids has adequate efficacy with little toxicity for the treatment of severe alopecia areata (AA).

OBJECTIVE

We wanted to evaluate the clinical efficacy of combination therapy using CsA with low-dose corticosteroid for the treatment of severe AA and we also wanted to determine the safe therapeutic concentration of CsA in the peripheral blood.

METHODS

We treated 34 cases of severe AA with combination therapy for 24 weeks and we evaluated the efficacy at 12 and 24 weeks. We monitored the peripheral blood concentration of CsA to determine the therapeutic range of CsA that has the fewest side effects.

RESULTS

Of the patients, 77.4% (n=24) and 22.6% (n=10) were classified in the responder and poor-responder groups, respectively. The mean trough concentration of CsA was 95.1 and 101.2 ng/ml in the responder and poor-responder groups, respectively. For the patients with side effects associated with CsA, the mean CsA concentration was 195.8 ng/ml.

CONCLUSION

We found that combination therapy with systemic CsA and low-dose corticosteroids effectively treats severe AA and this therapy results in a safe, therapeutic concentration of CsA in the peripheral blood.

Alopecia areata. Pathogenesis, diagnosis, and therapy

Alopecia areata is a common form of non-scarring alopecia that appears equally in males and females of any age, although children and adolescents are more commonly affected. The disorder is usually characterized by limited alopecic patches on the scalp, but more severe forms may affect the entire scalp (alopecia totalis) or body (alopecia universalis). Characteristic nail changes may also accompany hair loss. Alopecia areata has been linked with certain human leukocyte antigen (HLA) class II alleles, indicating a probable autoimmune etiology. Current research implicates T lymphocytes in the pathogenetic mechanism of disease. Other autoimmune diseases are also linked with alopecia areata. The diagnosis of alopecia areata is usually made clinically, although a biopsy is diagnostic for this condition. Treatment is challenging and aims at the regrowth of hair in affected individuals. Intralesional corticosteroid injections are widely used in mild disease. Topical anthralin and minoxidil may also be clinically efficacious. Topical sensitizers, such as squaric acid dibutlyester and diphenyl-cyclopropenone, are sometimes employed. Various therapies for the disease may have efficacy in different patients, making a universal treatment algorithm difficult to implement. Patients should be handled on an individual basis, with the final outcome based on the cosmetic regrowth of hair. Maintenance therapy is also important in patients that do achieve acceptable regrowth, necessitating a highly motivated patient and good rapport with the treating physician.

Twice weekly 5 mg dexamethasone oral pulse in the treatment of extensive alopecia areata

Thirty patients (20 males, 10 females) with widespread alopecia areata (25 extensive alopecia areata, 5 alopecia areata) for a mean period of 4.2 years were included in the study. All patients above 12 years were administered 5 mg dexamethasone oral pulse on two consecutive days every week. Three children (< 12 years) received 2.5 mg to 3.5 mg dexamethasone oral biweekly pulse. Patients who had received treatment for a minimum period of 12 weeks were evaluated for terminal hair growth. Complete to excellent (75-95%) hair growth was observed in 16 (63.3%) patients. Growth was good (50-74%) in 2 cases and poor (< 50%) in 3 (10%) cases. Six (20%) patients has no growth of terminal hair. Complete to excellent growth of hair was obtained after a mean period of 5.35 months (range 3-10 months). Relapse occurred in one case each after three and six months but hair regrew with re-treatment. Side effects of corticosteriods were frequent, seen in 8 (26.6%) patients, but were mild. In only one case, treatment had to be discontinued. We propose that twice weekly 5 mg dexamethasone oral pulse for six months may be considered as one of the modalities in the treatment of extensive long standing alopecia areata.
