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.

Diagnostic and therapeutic guidelines for plaque psoriasis - Brazilian Society of Dermatology.

Psoriasis is a chronic inflammatory disease that affects 1.3% of the Brazilian population. The most common clinical manifestations are erythematous, scaling lesions that affect both genders and can occur on any anatomical site, preferentially involving the knees, elbows, scalp and genitals. Besides the impact on the quality of life, the systemic nature of the disease makes psoriasis an independent risk factor for cardiovascular disease, especially in young patients with severe disease. By an initiative of the Brazilian Society of Dermatology, dermatologists with renowned clinical experience in the management of psoriasis were invited to form a work group that, in a partnership with the Brazilian Medical Association, dedicated themselves to create the Plaque Psoriasis Diagnostic and Treatment Guidelines. The relevant issues for the diagnosis (evaluation of severity and comorbidities) and treatment of plaque psoriasis were defined. The issues generated a search strategy in the Medline-PubMed database up to July 2018. Subsequently, the answers to the questions of the recommendations were devised, and each reference selected presented the respective level of recommendation and strength of scientific evidence. The final recommendations for making up the final text were worded by the coordinators.

Worldwide utilization of topical remedies in treatment of psoriasis: a systematic review.

OBJECTIVE: To review published literature describing the global use of topical antipsoriatics. MATERIALS AND METHODS: Search for English-language articles in Embase, Pubmed, PsycINFO and Cochrane Library. RESULTS: Fifty-four selected publications were found, describing psoriasis patients' use of topical antipsoriatics, using six different methods to collect data. The eight most frequently used topical treatments from the regions North/South America, North/Central/South Europe, Asia, Middle East and Australia were: corticosteroids used by 16-79%, complementary and alternative medicines used by 10-62%, phototherapies used by 0.4-75%, calcipotriol used by 4.2-73%, corticosteroid/calcipotriol combinations used by 3.3-71%, tar used by 0.8-66%, anthralin used by 15% and emollients used as monotherapy by 1-23%. Rates of patient-reported adherence to topical remedies ranged from 51% to 90% and rates of patient-reported satisfaction with topical as it pertains to symptom control ranged from 12% to 52%. CONCLUSION: The identified use patterns are varying and reflect a lack of data from large parts of the world and noncomparable studies using heterogeneous study designs. However, this study emphasizes the importance of medical professionals involvement of the patient with respect to choosing prescribed topical treatment and the possibility of patients' use of alternative treatments. More drug utilization studies, both survey and register based, from different parts of the world are needed to provide more conclusive evidence about patients' use of topical antipsoriatics.

Relationship between Histological and Clinical Course of Psoriasis: A Pilot Investigation by Reflectance Confocal Microscopy during Goeckerman Treatment.

Alterations of the skin microvasculature are known to play an important role in the development and maintenance of psoriatic skin lesions. In this study, we investigated lesional skin in 11 psoriatic patients during a modified Goeckerman treatment using reflectance confocal microscopy (RCM) to study the relationship between clinical clearance and histological normalization of psoriatic skin and the significance of histological abnormalities on the course of disease. The treatment regimen resulted in a significant reduction of the Psoriasis Area and Severity Index (PASI) as well as capillary and papillary diameters (p < 0.0001). The capillary and papillary diameters were still enlarged when compared to those in normal skin (p < 0.001). Capillary and papillary diameters correlated with each other prior to and after treatment (correlation coefficient = 0.63 and 0.64, p = 0.01 and 0.002, respectively) but not with the PASI. Capillary and papillary diameters after treatment and percentage reduction of the PASI during treatment seemed to be better predictors for the clinical course of relapse than the PASI after treatment. These findings make the subclinical changes of psoriatic skin vessels and dermal papillae a legitimate target for treatment. Further investigations of a large group of patients are needed to evaluate the potential of RCM findings as successor of the PASI in the monitoring of psoriasis.

Methotrexate in pediatric plaque-type psoriasis: Long-term daily clinical practice results from the Child-CAPTURE registry.

BACKGROUND: Evidence on effectiveness and safety of methotrexate (MTX) in pediatric psoriasis is scarce. OBJECTIVES: To study the effectiveness and safety of MTX in pediatric plaque-type psoriasis and its influence on quality of life (Qol) in daily clinical practice. METHODS: Subset analysis of prospectively collected data extracted from the Child-CAPTURE registry, a single center, longitudinal, long-term, observational daily practice cohort of pediatric psoriasis patients. A maximum dose between 0.14 and 0.63 mg/kg once weekly was prescribed in 25 children. Primary endpoints were percentages of patients with ≥ 75% improvement in the Psoriasis Area and Severity Index (PASI) at week 12 and 24. RESULTS: PASI75 was achieved in 4.3% and 33.3% of patients at week 12 and 24, whereas 40% and 28.6% reached PASI 75 at week 36 and 48. Median PASI and body surface area decreased from 10.0 (range 3.8-42.4) and 11.0 (range 3.5-72.0) at baseline to 4.3 (range 0-19.8) and 2.6 (range 0.0-39.6) at week 24, respectively. Physician Global Assessment improved significantly from 3.0 to 1.2 at week 24. A significant decrease in Children's Dermatology Life Quality Index from 9.0 to 3.8 at week 24 was found. Most reported adverse events were severe nausea (n = 5), infections requiring antibiotics (n = 5) and tiredness (n = 4). CONCLUSIONS: MTX shows a positive effect on PASI scores, improves Qol and has a reasonable safety profile.

Current treatment of alopecia areata.

Treatment of alopecia areata is dependent on age of patient as well as the extent and duration of scalp involvement. Treatments include steroids, topical immunotherapy, topical minoxidil, anthralin, and immunosuppressants. Each case must be dealt with on a customized individual basis.

Childhood psoriasis: often favorable outcome.

(1) Plaque psoriasis is the most common form of psoriasis in children. Topical agents should be tried first, especially well-tolerated products such as emollients. Topical corticosteroids are sometimes useful during exacerbations but, given adverse effects, they should only be used for short periods; (2) UVB phototherapy is an option for extensive psoriasis refractory to local treatments, but it carries a long-term risk of skin cancer. Immunosuppressants have not been well assessed in this setting, but methotrexate has been better evaluated than the others.

Actualización terapéutica en alopecia areata / Update on the Treatment of Alopecia Areata

La alopecia areata es una alopecia no cicatricial telogénica de base autoinmune. Se estima que origina un 2 % de las consultas dermatológicas y puede aparecer a cualquier edad, aunque es más frecuente en pacientes jóvenes. Su tratamiento va a depender de varios factores, fundamentalmente de la extensión de la enfermedad, de la edad del paciente, así como de medidas locales y sistémicas. Mientras que los tratamientos locales tienen como objetivo conseguir el recrecimiento piloso, sin influir en la evolución de la enfermedad, los tratamientos sistémicos pueden interferir en la evolución de la misma, siendo ambos medidas paliativas. En este trabajo revisamos la mayoría de las opciones terapéuticas descritas en la literatura para la alopecia areata (AU)

Alopecia areata is nonscarring telogenic alopecia of autoimmune etiology. It is estimated to be the presenting complaint in 2 % of dermatologic consultations, and can appear at any age although it is more common in young patients. Treatment depends on several factors, such as extent of the disease and age, and may be local or systemic. Local treatments aim to achieve hair regrowth, but do not alter the underlying condition, whereas systemic treatments can modify the course of the disease. In neither case does treatment provide a cure. In this article, we review most of the therapeutic options described in the literature for alopecia areata (AU)

Psoriasis: characteristics, psychosocial effects and treatment options.

Psoriasis is a complex chronic non-infectious inflammatory skin disease with many different presentations. The classic presentation is of well-defined red plaques with silver scale. The characteristic scale makes the disorder highly visible and intrusive on the patient's lifestyle. The visible nature of the disease ensures that psoriasis has both physical and psychosocial effects. In normal skin, epidermal cell reproduction and proliferation takes 28 days. In psoriasis, this process is considerably accelerated to approximately four days, resulting in the deposit of immature cells on the skin. While the exact cause of this process is unknown, certain environmental and genetic factors are known to be provoking factors. Disease management will be dependent on disease severity, psychosocial effects and the patient's lifestyle. To effectively treat this disease the nurse must be skilled in psoriasis management, and in patient education and motivation. This article reviews the characteristics, aetiology, psychosocial effects and treatment strategies of psoriasis.

A comparison of twice-daily calcipotriol ointment with once-daily short-contact dithranol cream therapy: quality-of-life outcomes of a randomized controlled trial of supervised treatment of psoriasis in a day-care setting.

BACKGROUND: Calcipotriol ointment and short-contact dithranol cream therapy are well-established topical treatments for psoriasis. Quality of life, i.e. the physical, psychological, and social functioning and well-being of the patient, has become an essential outcome measure in chronic skin disease. OBJECTIVES: To compare the quality-of-life outcomes of calcipotriol ointment with that of short-contact dithranol cream in a supervised treatment regimen, and to determine the degree of improvement in quality of life these topical treatments can accomplish. METHODS: In a multicentre randomized controlled trial in six centres in the Netherlands, 106 patients with chronic plaque psoriasis were included, 54 receiving calcipotriol ointment twice daily and 52 dithranol cream once daily in a 12-week intensive treatment programme. Patients were treated at the day-care centre, using the care instruction principle of daily visits during the first week and twice-weekly visits subsequently for up to 12 weeks. Quality of life was assessed with the Skindex-29 and the Medical Outcomes Study 36-item Short-Form General Health Survey (SF-36). RESULTS: At the end of treatment, no statistically significant differences were found between the calcipotriol and the dithranol group in any of the quality-of-life domains or scales of the Skindex-29 and the SF-36. Over time, a significant improvement of quality of life was found on all three scales of the dermatology-specific Skindex-29, predominantly of a moderate magnitude. In the calcipotriol group, a significant change of a small magnitude was found in the Physical Component Summary of the SF-36. No significant changes were found in the Mental Component Summary (or on any of the eight scales composing the questionnaire) of the SF-36. CONCLUSIONS: The hypothesis was confirmed, that no statistically significant differences in improvement of quality of life could be found between calcipotriol ointment and dithranol short-contact cream in a day-care setting. Given this result, both calcipotriol and dithranol can be welcome alternatives for the patient. Calcipotriol, being more practical and patient friendly, can be considered as a first-line approach in clinical practice. However, in patients recalcitrant to calcipotriol and/or other topical treatments, preference should be given to the dithranol regimen. Topical treatment in combination with interventions explicitly focusing on improvement of coping behaviour and psychosocial functioning may further increase the degree of improvement in the psychosocial domains of quality of life. The results of this study are likely to give further evidence to the notion that the generic SF-36 is little or not responsive to small to moderate changes in quality of life in mild to moderate psoriasis.

Psoriasis of the nail: anatomy, pathology, clinical presentation, and a review of the literature on therapy.

Psoriasis is a chronic skin disease that affects millions of people throughout the world. Even though cutaneous signs and symptoms are the most common clinical manifestations, the nails can be involved in up to 50% of cases, and their involvement remains an important yet often overlooked aspect of the disease. There is a broad spectrum of nail dystrophies associated with psoriasis, ranging from the common pitting and loosening of the nail plate to the less frequent discoloration and splinter hemorrhages seen in the nail bed. This article discusses the normal anatomy and embryology of the nail unit as well as the current understanding of the pathogenesis of the disease. It also provides an extensive review of the existing literature with respect to psoriatic nail therapy. Although there have been many recent advances in the treatment of the cutaneous form of the disease-most notably in the field of immunotherapies-the options for nail psoriasis are far more limited. While a number of treatment alternatives currently exist for nail disease, the general paucity of clear evidence regarding these choices often makes it difficult to select the most efficient, safe, and optimal treatment for the patient. Even though the current literature has shown some support for the use of topical, intralesional, radiation, systemic, and combination therapies for nail psoriasis, the available studies lack sufficient power to extrapolate a standardized therapeutic regimen. Therefore, until better-documented evidence validating the treatment options emerges within the literature, clinicians and patients are left with a vague and relatively unproven approach to psoriatic nail disease.

Alopecia areata.

Alopecia areata (AA) is a nonscarring, autoimmune, inflammatory, hair loss on the scalp, and/or body. Etiology and pathogenesis are still unknown. The most common site affected is the scalp. Histopathology is characterized by an increased number of the catagen and telogen follicles, the presence of inflammatory lymphocytic infiltrate in the peribulbar region ("swarm of bees"). Corticosteroids are the most popular drugs for the treatment of this disease. Etiologic and pathogenic mechanisms, as well as other current treatments available will be discussed in this article.

Treatment of childhood psoriasis.

Psoriasis is a common disease in children and adolescents. Because of the chronic course of the disease, appropriate choice of therapy in particular stage of the disease, so-called rotation therapy, is of paramount importance. This article provides a review of therapeutic options for childhood psoriasis. Local therapy for psoriasis in children consists of corticosteroid preparations, calcipotriol, tars and dithranol, local retinoids, and local immunomodulators. Phototherapy (narrow band UVB, photochemotherapy PUVA baths) is now a part of psoriasis therapy in children. Systemic therapy retinoids (acitretin) methotrexate, cyclosporine is only used in severe forms of the disease such as erythrodermic, pustular and arthritic psoriasis. All these therapeutic options can be used as monotherapy or in various combinations.

The effect of treatment on quality of life in psoriasis patients.

Psoriasis is a chronic skin disease with substantial impact on patients' social and relational ways of living and subsequently on their quality of life. The aim of this study was to evaluate the health-related quality of life (HRQoL) of patients with moderate to severe psoriasis treated with short contact dithranol treatment, UVB phototherapy or inpatient dithranol treatment. HRQoL was evaluated in an open randomized multicentre study by appliance of the Dutch short form of the Sickness Impact Profile and the Psoriasis Disability Index; 250 patients were included. Successful short contact dithranol treatment and UVB phototherapy both led to a comparable improvement in HRQoL immediately after treatment until the end of the follow-up (maximum 1 year). Inpatients experienced a more impaired HRQoL and showed no significant improvement in HRQoL directly following treatment. At the end of the study HRQoL became comparable for all treatment groups. All three treatments led to substantial improvement in HRQoL; however, patients treated by short contact treatment or UVB showed a better HRQoL than inpatients.
