Several treatment modalities are available for the management of alopecia areata (AA); however, no therapy is universally effective and treatment can be frustrating in severe cases, with low response and high recurrence rates. Recent studies show that the JAK/STAT pathway plays a central role in the pathogenesis of this disease by determining the crosstalk between the infiltrating CD8+ T cells and the hair follicles, suggesting a role of JAK inhibitors in the treatment of AA. However, reports on the off-label use of these more expensive targeted agents have shown variable results...

BACKGROUND: Alopecia areata is an immune-dependent disorder characterized by the interaction of T-lymphocytes with follicular antigens. Recent studies have shown the existence of a local renin-angiotensin system in the skin, where angiotensin-converting enzyme (ACE) plays a role in autoimmunity and inflammation. AIM: The objective of this study was to evaluate serum and tissue ACE activity in patients with alopecia areata. METHODS: This case-control study was conducted on patients with alopecia areata and healthy controls...

Importance: The incidence of thyroid disease in children with alopecia areata (AA) has been widely studied with no consensus on whether a true association with AA exists. In addition, screening practices for thyroid dysfunction in children with AA vary widely among clinicians. Objective: To reduce health care costs, eliminate unnecessary testing, and standardize clinical practices, we sought to characterize thyroid function in children with AA to establish guidelines for screening...

BACKGROUND/AIMS: Alopecia areata is a common immune-mediated hair condition with limited treatment options and success rates. There is evidence that statins, which are used for reducing atherogenesis and cardiovascular disease, have immunomodulatory activities and therefore may also be used for treatment of selected dermatologic conditions, including alopecia areata. Among treatments evaluated for alopecia areata, oral simvastatin/ezetimibe therapy is currently under the scrutiny of expert opinion...

Alopecia areata is a common autoimmune disorder leading to hair loss. It usually affects individuals under the age of 40, and first appearance in older subjects is considered uncommon. Here, we report 2 cases of rapidly progressing alopecia areata, which appeared for the first time in adults. Patient 1 had alopecia universalis, which preceded the identification of hepatosplenic T-cell lymphoma, a rare form of lymphoma. Patient 2 suffered from the ophiasis type of alopecia areata, presenting for the first time following chemotherapy for non-Hodgkin B-cell lymphoma...

BACKGROUND: Alopecia areata (AA) is a common, recurrent, autoimmune hair disorder. It has been found that vitamin D deficiency is associated with many autoimmune diseases. AIMS: The current study aimed to estimate serum levels of 25-hydroxy vitamin D in patients with AA. MATERIALS AND METHODS: This case-control study included 60 patients with AA and 60 age, gender, skin phototype, and body mass index-matched healthy subjects as a control group...

BACKGROUND: Alopecia areata (AA) is an autoimmune disease characterized by hair loss mediated by CD8+ T cells. There are no reliably effective therapies for AA. Based on recent developments in the understanding of the pathomechanism of AA, JAK inhibitors appear to be a therapeutic option; however, their efficacy for the treatment of AA has not been systematically examined. METHODS: This was a 2-center, open-label, single-arm trial using the pan-JAK inhibitor, tofacitinib citrate, for AA with >50% scalp hair loss, alopecia totalis (AT), and alopecia universalis (AU)...

OBJECTIVES: This study investigated ocular findings in patients with alopecia. METHODS: A total of 42 patients with alopecia (31 male, 11 female; 84 eyes) and 45 healthy individuals (28 male, 17 female; 90 eyes) were enrolled in the study. Of the patients with alopecia, 34 had alopecia areata, seven had alopecia universalis, and one had ophiasis alopecia. Seven patients had eyebrow involvement and seven had eyelash involvement. Autorefractometry, keratometry, visual acuity, central corneal thickness and intraocular pressure (IOP) measurements, bilateral anterior and posterior segment examinations, Schirmer's tests, and visual field examinations were performed in both groups...

OBJECTIVE: To provide family physicians with a background understanding of the epidemiology, pathogenesis, histology, and clinical approach to the diagnosis of alopecia areata (AA). SOURCES OF INFORMATION: PubMed was searched for relevant articles regarding the pathogenesis, diagnosis, and prognosis of AA. MAIN MESSAGE: Alopecia areata is a form of autoimmune hair loss with a lifetime prevalence of approximately 2%. A personal or family history of concomitant autoimmune disorders, such as vitiligo or thyroid disease, might be noted in a small subset of patients...

There are no widely accepted therapy protocols for severe alopecia areata (AA). We treated 65 children/adolescents with AA affecting >30% of scalp. Fourty-three percent of patients had AA plurifocalis (AAP). Fifty-seven percent had AA subtotalis (AAS), AAP+ophiasis (AAP+OPH), and alopecia totalis/universalis (AT/AU). Long-term follow-up (median 96 months) data were available for 69% of patients. Oral dexamethasone (prednisolone 5 mg/kg equivalent) was given once in 4 weeks. Patients received 6, 9, or 12 pulses...

OBJECTIVES: The objectives were to assess the demographical pattern, clinical presentation and therapeutic response in a cohort of patients with alopecia areata (AA) in Sri Lanka. METHODS: Hospital-based observational study of 290 adults aged 18 years or above. RESULTS: Alopecia areata was commoner in men (M:F=1.3:1). Age of onset was between 20-35 years (median 31 years) in 61%. Those with juvenile-onset AA (≤ 17 years, n=5) showed severe disease with many relapses and resistance to therapy...

Alopecia areata is a chronic inflammatory non-scarring condition affecting the hair follicle that leads to hair loss ranging from small well defined patches to complete loss of all body hair. In about 80% of affected individuals there is spontaneous regrowth within a year. It can present at any age, although 60% of patients develop their first episode of hair loss before the age of 20. There is a family history of alopecia areata in 20% of cases indicative of a genetic basis. A positive family history is prognostic of troublesome alopecia areata, as are onset in childhood, ophiasis (involvement of the scalp hair margins), nail changes and concurrent atopic disease...

BACKGROUND: Spontaneous recovery of severe alopecia areata is rare and the condition is difficult to treat. OBJECTIVE: The aim of this study is to investigate and compare the effects and safety of steroid pulse therapy between oral and intravenous administrations between 1999 and 2010 at the Department of Dermatology, National Cheng Kung University Hospital. METHODS: Data were retrospectively retrieved. A satisfactory response was defined as more than 75% hair regrowth in the balding area...

Alopecia areata is a complex genetic, immune-mediated disease that targets anagen hair follicles. The disease affects children and adults and is characterized by round or oval patches of hair loss, loss of all scalp hair (alopecia totalis), body hair (alopecia universalis), or ophiasis pattern hair loss. Patients may also present with patchy loss in multiple hair-bearing areas. Commonly associated diseases include asthma, allergic rhinitis, atopic dermatitis, thyroid disease, and automimmune diseases, such as thyroiditis and vitiligo...

BACKGROUND/OBJECTIVE: Alopecia areata may occur at any age, though usually before the age of 20 years. Treatment often consists of systemic steroids administered as high-dose bolus infusions. This study sought to investigate the effectiveness and side effects of intravenous high-dose pulse corticosteroids in children with alopecia areata and to identify prognostic factors for successful treatment. METHODS: Patients treated with pulse corticosteroids for alopecia areata in 2001-2008 at the day care unit of a tertiary pediatric medical center were identified by computerized file search and clinical treatment and outcome data were collected...

BACKGROUND AND OBJECTIVES: Both ablative and non-ablative fractional lasers have been applied to various uncommon hair disorders. The purpose of this study was to demonstrate the clinical effects of fractional laser therapy on the course of primary follicular and perifollicular pathologies and subsequent hair regrowth. MATERIALS AND METHODS: A retrospective review of 17 patients with uncommon hair disorders - including ophiasis, autosomal recessive woolly hair/hypotrichosis, various secondary cicatricial alopecias, pubic hypotrichosis, frontal fibrosing alopecia, and perifolliculitis abscedens et suffodiens - was conducted...

BACKGROUND: Emotional stress has been associated with the development of alopecia areata (AA) and androgenetic alopecia (AGA). Emotional intelligence (EI), a component of general intelligence, is thought to govern the recognition, expression, and control of stress and other emotions. People with low EI are unable to adequately control stress in everyday life. OBJECTIVE: To investigate EI differences between AA and AGA patients and a control population. METHODS: Thirty-five AGA patients and 42 AA patients, with patchy (n  =  28), ophiasis (n  =  5), totalis (n  =  5), and universalis (n  =  4) distribution of hair loss, completed a 133-item Emotional Quotient-Inventory (EQ-I ) psychometric assessment...

We present a case series of 3 black women who presented with alopecia along the anterior and posterior hairline on physical examination. The initial clinical suspicion was traction alopecia from tension placed on the hair and traumatic removal of hairweaves. Two cases were supported histologically as traction alopecia, while the remaining case was alopecia areata in an ophiasis pattern. Interestingly, the case of alopecia areata was associated with the mildly traumatic removal of a weave. Traction alopecia may present in an ophiasis pattern from hair care practices...

OBJECTIVE: To use intensive regimen of pulse steroid in the severe forms of Alopecia areata. METHODS: This prospective randomized study was conducted at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between 2003 to 2009. Patients with Alopecia universalis, Alopecia totalis, or Alopecia ophiasis were assigned to one of the 3 treatment groups: Group A received oral mega pulse methylprednisolone (MP) for 3 consecutive days once every 2 weeks for 24 weeks; Group B received 2 consecutive daily pulses every 3 weeks; and Group C received 3 consecutive daily pulses every 3 weeks...
