An open-label study with etanercept revealed no efficacy in the treatment of moderate to severe alopecia areata In addition, patients who have been treated with adalimumab, infliximab or etanercept for other autoimmune disorders have developed alopecia areata during the course of treatment, Finally, small randomized trials of efalizumab anti-CD11A and alefacept anti-CD2 showed no benefit in alopecia areata.
Non-medical treatments Author Manuscript Laser Causes of scalp inflammation and hair loss therapy may have a positive effect on patients with alopecia areata.
The Excimer laser ultraviolet laser is currently commonly used and may offer a safe and effective alternative to medical treatments. However, recent reviews and reports indicate that randomized controlled clinical trials are needed to confirm this is a better approach than medical treatment, Causes of scalp inflammation and hair loss the only result might be an increase in hair shaft diameter, Preclinical trials with the mouse model for alopecia areata did not show efficacy using a laser comb Retrospective reviews reported low response rates or response similar to natural Causes of scalp inflammation and hair loss of the disease Relapse rates are high and continued treatment is usually needed to maintain hair growth, which may lead Causes of scalp inflammation and hair loss an unacceptably high cumulative UVA dose.

Patchy alopecia affecting the scalp is the most common type. Skin biopsies of alopecia areata affected skin show a lymphocytic infiltrate in and around the bulb or the lower part of the hair follicle in anagen hair growth phase.
A breakdown of immune privilege of the hair follicle is thought to be an important driver of alopecia areata. Genetic studies in patients and mouse models showed that alopecia areata is a complex, polygenic disease. Several genetic susceptibility loci were identified associated with signaling pathways that are important to hair follicle cycling and development.

Author Manuscript Correspondence Causes of scalp inflammation and hair loss J. Author contributions Introduction C. Competing interests L. Pratt et al. Page 2 Author Manuscript Introduction Alopecia areata AA is a common type of hair loss or alopecia in humans; it is an autoimmune disease with a variable, typically relapsing or remitting, course that can be persistent — especially when hair loss is extensive.
Alopecia areata is the second-most frequent non-scarring alopecia, after male and Causes of scalp inflammation and hair loss pattern alopecia Box 1. Clinical patterns of hair loss in alopecia areata are usually very distinct. The most common pattern is a small annular or patchy bald lesion patchy alopecia areatausually on the scalp, that can progress to total loss of scalp hair only alopecia totalisand total loss of all body hair alopecia universalis Box 2.
Box 1 Primary hair loss disorders Author Manuscript Non-scarring alopecias Non-scarring types of alopecia also known as non-cicatricial alopecias refer to hair loss due to changes in hair cycle, hair follicle size, hair breakage or a combination of these, with preservation of the hair follicle.
Nat Rev Dis Primers. Scarring alopecias Scarring types of alopecia also known as cicatritial alopecias refer to forms of hair Dietas faciles in which hair follicles are destroyed Causes of scalp inflammation and hair loss to inflammation, or rarely, malignancy such as cutaneous lymphoma.
Affected skin shows loss of follicular ostia the openings of the hair follicle though which the hair fiber emerges through the skinbut the early stages Causes of scalp inflammation and hair loss resemble alopecia areata. Genetic hair disorders Author Manuscript Many syndromic and non-syndromic types of hair loss are due to single gene mutations.

The mutations can affect follicular development, normal hair cycling and hair fiber fragility; most conditions are present from infancy or childhood.
Inflammation of the hair follicles in alopecia areata mediated by leukocytes was described over a century ago yet the involvement of the immune Causes of scalp inflammation and hair loss in the pathogenesis of alopecia areata has only been recognized as the primary underlying cause since the late s, when several immune related and several key pathogenetic effector cells were identified 1,2.
The registry enabled the application of genome-wide association studies GWAS that have identified candidate genes associated with susceptibility to alopecia areata4, as well as an evaluation of important epidemiological and socio-medical Dietas faciles, such as quality of life QOL Causes of scalp inflammation and hair loss.
Concurrently, rodent models6—8 that faithfully recapitulate the disease in humans and have enabled functional studies have been identified, and quantitative trait locus QTL mapping a technique that links variations in DNA to phenotype 9, 10 has been performed.

Together, all these techniques and associated observations have Causes of scalp inflammation and hair loss firmly established that alopecia areata is a complex, polygenic, immune-mediated disease that can now be interrogated to identify biomarkers to differentiate its severity or subtypes9. In this Primer, we describe the current knowledge on the epidemiology of alopecia areata from a global perspective, the underlying pathophysiology, and genetic basis of this complex Nat Rev Dis Primers.
Page 5 Author Manuscript disease, concurrent diseases, diagnostic approaches, differential diagnoses, and current treatment approaches, as well as new breakthroughs. Epidemiology A high degree of phenotypic and genotypic variability observed in AA, which is Causes of scalp inflammation and hair loss genetic disease determined by genetic and environmental factors.

Studies performed in a small number of patients should be viewed with caution. One study in Olmsted County Minnesota, USA based on data collated between — from patients with alopecia areata who were seen by a dermatologist showed that overall incidence was A follow-up study of this population form — found that the cumulative incidence increased almost linearly with age and that the lifetime incidence of alopecia areata was 2.
This skewed incidence might be an artifact since women Causes of scalp inflammation and hair loss seek medical attention as they age more than men. Causes of scalp inflammation and hair loss, other population surveys suggest that alopecia areata is slightly more common in men One study found that men were more likely to be diagnosed at an earlier age than women No studies have determined if alopecia areata prevalence is different between ethnic groups Most studies report no significant differences in the age of onset, duration, or type of alopecia areata by sex or ethnicity The onset of alopecia areata might be at any age; however, most patients develop the condition before the age of 40 years Causes of scalp inflammation and hair loss the with a mean age of onset between 25 and 36 years Early-onset alopecia areata mean age of onset between ages 5—10 years predominantly presents as a more severe subtype, such as alopecia universalis17,22—25 Box 2.

One study found that men were Causes of scalp inflammation and hair loss likely to have a positive family history than women The occurrence of the disease in identical twins29—34, siblings35 and families with several generations of affected individuals36—38 indicates that this alopecia areata has a heritable basis.
Most of the early human genetic studies were candidate gene association studies, in Nat Rev Dis Primers. Page 6 Author Manuscript which linkage to specific genes or groups of genes was the focus.
These studies focused on the human leukocyte antigen class II HLA-D region on human chromosome 6 as the most likely region for genes that regulate susceptibility or resistance to alopecia areata Familybased linkage studies and GWAS analyses, which were greatly enabled by the repository of the National Alopecia Areata Registry3, identified linkage or association on many chromosomes, which suggests that alopecia areata is a very complex polygenic disease4, These results confirmed earlier QTL analysis studies using an alopecia areata mouse model, often with similar, if not identical results41, Concurrent Diseases Author Manuscript Alopecia areata is associated with several concurrent diseases comorbidities including depression, anxiety, and several autoimmune diseases including thyroid disease hyperthyroidism, hypothyroidism, goiter ant thyroiditislupus erythematosus, vitiligo, psoriasis, rheumatoid arthritis and inflammatory bowel disease17, The frequency of these concurrent diseases varies between geographically separate populations, which may suggest genetic variability within these different populations.
A retrospective study in Taiwan found that patients with alopecia areata had higher hazard ratios for autoimmune diseases such as rheumatoid arthritis, systemic Causes of scalp inflammation and hair loss erythematosus and psoriasis within the 3-year follow-up period than healthy controls In addition, increased prevalence of other forms of inflammatory skin disease such as atopic dermatitis, vitiligo, psoriasis and lichen planus were found than Causes of scalp inflammation and hair loss controls, suggesting that patients with alopecia areata are at increased risk of developing variety Como empezar a bajar de peso T-cell Causes of scalp inflammation and hair loss inflammatory skin diseases Severe alopecia areata might be accompanied by nail changes Atopic diseases, such as sinusitis, asthma, rhinitis, and especially atopic dermatitis, are also more common than expected in populations with alopecia areata43, and are associated with early-onset and more severe forms of hair loss.
In a Korean population, atopic dermatitis was significantly more common in patients with early-onset alopecia areata, whereas thyroid disease was the most common in late-onset disease46; Causes of scalp inflammation and hair loss were similar in Sri Lanka In a review of 17 studies, investigators found higher odds of atopic dermatitis in patients with alopecia totalis or alopecia universalis compared to those with patchy alopecia areata In a large-scale epidemiological study in Taiwan investigators found a correlation between prior herpes zoster outbreaks with alopecia exposure within 3 years, suggesting that stress might trigger alopecia areata Several studies, with and without controls, demonstrated a high prevalence of thyroid autoimmunity associated with alopecia areata49, whereas others found lower frequencies than in earlier studies, indicating that there is no need for detailed investigations into these diseases without a clinical history to suggest they are present The initial genetic studies concentrated on single genes that were known to be involved in related autoimmune Nat Rev Dis Primers.

Page 7 Author Manuscript diseases. Interestingly, many of these genes did in fact play a role in alopecia areata in addition to inflammatory bowel disease, multiple sclerosis, psoriasis, and type 1 diabetes mellitus Owing to the focus on an autoimmune etiology, the HLA region, which encodes MHC molecules in humans, was initially identified as a major contributor to the alopecia areata phenotype51— The HLA region is one of the most gene-dense regions of the genome and encodes for key immune regulators Author Manuscript Subsequent large-scale genetic studies have added to the list of genes associated with alopecia areata and further validated the role of the HLA region genes.
For example, the several GWAS analysis in humans have identified 14 genetic loci associated with alopecia areata, many of which are known to be involved in immune function4,53, The dependency of these cells on IL15 signaling for their survival provided a rationale for using Janus Kinase JAK inhibitors to target the downstream effectors of this pathway in developing new therapeutic approaches. Adelgazar 72 kilos Manuscript In addition, gene expression studies have been used to validate these genetic studies and to assess local gene expression changes in affected areas.
These studies have also identified more genes whose expressions are changed Causes of scalp inflammation and hair loss disease progression41,42,57, Gene expression profiling studies have revealed predominant signatures of the Interferon gamma pathway and its related cytokines, as well as a predominant signature for cytotoxic T Causes of scalp inflammation and hair loss, both of which are mediated by JAK kinases as their downstream effectors.
The emergence of these signatures further refined the focus using small-molecule JAK inhibitors. Recently, associations between alopecia areata and copy number variations CNV were found using genome-wide scans Box 3 Mouse Gene Mouse Chr.
Author Manuscript Author Manuscript Although most genetic studies in both humans and mice focus on the autoimmune aspects of alopecia areata, the hair loss is Causes of scalp inflammation and hair loss due to hair shaft fragility and breakage.
In the mouse model for alopecia areata, cysteine-rich secretory protein 1 Crisp1 was identified as a candidate gene within the major alopecia areata locus Alaa1 using a combination of QTL analysis, shotgun proteomics60,61, and in situ hybridization Whether this protein plays a role in severity of human disease remains to be determined.
Such findings suggest an even more complex genetic involvement, with genetic factors not only involved in disease initiation but also in Causes of scalp inflammation and hair loss pleomorphic clinical presentation.

Pathodynamics of hair loss The dynamics of hair growth FIG. An early study63 found that hair loss was preceded by a large increase in the proportion of telogen hairs and an increase in the proportion of abnormal hair shafts, Causes of scalp inflammation and hair loss resulted in increased fragility of the shaft dystrophic hairs compared with normal hair from unaffected patients.
In normal circumstances, most hairs are in the anagen phase which is typically divided into Nat Rev Dis Primers. In fact, the initial event in alopecia areata seemed to be a rapid progression of hair follicles from the anagen phase to the catagen and telogen phases. Follicles that were less severely affected remained in anagen but produced dystrophic hair shafts that eventually underwent progression to telogen. Biopsies from the margins of Dietas rapidas lesions of alopecia areata Causes of scalp inflammation and hair loss large numbers of follicles in catagen or early telogen Whether follicles attained telogen via normal catagen transition was not determined.
The affected follicles do re-enter the anagen phase. Author Manuscript Exclamation point hairs a type of dystrophic hairs are a key characteristic of AA and are not normally seen in healthy controls Although exclamation point hairs might have a well-formed club root identical to that of a normal telogen hair, Causes of scalp inflammation and hair loss root is often narrowed and club hairs fall out more readily than normal.
These changes suggested defective anchoring of the hair within the follicle. Author Manuscript Peribulbar inflammation is commonly found around anagen follicles that are adjacent to the focal lesion The affected follicles do re-enter anagen.
