Alopecia areata is frequently associated with immune-medi- ated diseases with skin manifestations such as psoriasis and lichen planus, or without skin manifestations such as autoimmune thyroiditis and idiopathic thrombocytopenic purpura. Helicobacter py/ori （H. pylorl） infection is present in around 50% of the world＇s population and has been associated with a variety of immune-mediated extra-digestive disorders including autoimmune thyroid- itis, idiopathic thrombocytopenic purpura, and psoriasis. A case of a 43-year old man with an 8-too history of alopecia areata of the scalp and beard is presented. The patient was being treated by a dermatologist and had psychiatric support, without any improvement. He had a history of dyspepsia and the urea breath test confirmed H. pylori infection. The patient went into remission from alopecia areata after H. pylori eradication. If such an association is confirmed by epidemiological studies designed for this purpose, new therapeutic options could be available for these patients, especially in areas where infection with H, pylori is highly prevalent.展开更多

The gross appearance, growth characteristics, pathological changes in skin, and major organs of B6.KM-AA mice were observed. Counts and proportions of CD4＋ and CD8＋ T lymphocytes in peripheral blood were determined by flow cytometry. Results show that congenic B6.KM-AA mice were obtained after 10 generations of backcrossing/intercrossing. B6.KM-AA mice grew slower than B6 control mice and AA skin lesions were developed by four weeks of age. The number of hair follicles was reduced, but hair structures were normal. Loss of hair during disease progression was associated with CD4＋ and CD8＋ T lymphocytes infiltration peri- and intrahair follicles. No pathological changes were found in other organs except for the skin. In the peripheral blood of B6.KM-AA mice, the percentage of CD4＋ T cells was lower and percentage of CD8＋ T cells higher than in control mice. These findings indicate that B6.KM-AA mice are characterized by a dysfunctional immune system, retarded development and T-cell infiltration mediated hair loss, making them a promising new animal model for human alopecia areata.展开更多

In certain cases, hair regrowth takes a polycyclic pattern simulating a target, so called targetoid phenomena. Objective: To screen all cases of treated alopecia areata for hair targetoid regrowth pattern. ?Methods: This is an observational study, was conducted in Dermatology Department of Baghdad Teaching Hospital in Iraq, during the period, August 2017 to October 2017. All cases treated for alopecia areata with IM triamcinolone 20 - 40 mg injection every 2 weeks with topical clobetasone ointment and zinc sulfate 2 mg/kg/day for 2 months, were examined for the targetoid concentric hair regrowth pattern. Result: Among all cases of alopecia areata, seven patients were recorded to have the targetoid concentric hair pattern, which seen 2 - 4 weeks after therapy, their ages ranged from 4 to 25 years old with a mean 14.5, all of them were males. All these patients returned back with hair growth in a form of rings of hair growth alternating with rings of little or no hair growth forming a typical picture of target. Conclusion: Targetoid polycyclic concentric hair regrowth pattern is an important phenomenon seen in patients receiving treatment for alopecia areata, which is a good sign of recovery where its etiopathogenesis could not well be elucidated but alternating immunological reactions could explain this targetoid pattern.展开更多

The development of organ-specific autoimmune reactions directed against anagen hair follicles seems to play a key role in the pathogenesis of alopecia areata. However, the triggering antigen（s） responsible for inducing autoimmune phenomena in these individuals remain unknown. Viral, bacterial or fungal pathogens have been implied as possible triggering factors of autoimmune reactions. The present study aims to identify the role of dematiaceous fungi in the pathogenesis of alopecia areata. 30 patients diagnosed clinically as alopecia areata and 30 normal age matched persons have undergone mycological examination. Mycology examination of the epidermal scrapings was done by DME （direct microscopic examination）, culture on SDA （sabouraud＇s dextrose agar） and imaging. There is significantly higher percentage of positive results for Alternaria species by culture on sabouraud＇s agar in patients group （20%） compared to controls （13.3%） P-value 〈 0.05. The possible role of Alternaria antigens （e.g. antigens involved in melanin synthesis） in triggering autoimmunity in alopecia areata still needs further research on a wider scale of cases.展开更多

METHODS: A cross-sectional study was conducted, which evaluated 109 individuals. Ten with down syndrome(DS) and alopecia areata(AA), ten with DS without AA and ten with AA without DS, and their fami-lies. The individuals were matched by gender and age. The following data were computed: gender, age, ethnic group, karyotype, clinical presentation and family history of alopecia areata. Descriptive analysis: measures of central tendency and frequency distribution. Inferential analysis: Fisher's exact test to compare categorical data between the three groups and Kruskal-Wallis ANOVA test for numerical data.RESULTS: Seventy per cent of evaluated individuals in the DS and AA group were male; presented mean age of 18.6(SD ± 7.2) years and 70% were Caucasian. We observed involvement of the scalp, with a single lesion in 10% and multiple in 90% of subjects. It was observed that there is no significant difference in the frequency distributions of the alleles HLA loci A, B, C, DRB1 and DQB1 of subjects studied. However, according to Fisher's exact test, there is a trend(P = 0.089) of DS group to present higher proportions of HLA-A 36 and HLA-B 15 than the AA group and AA and DS group.CONCLUSION: There was a tendency for the DS group, to present proportion of HLA-A 36 and HLA-B 15 higher than the AA group and group of individuals with AA and DS. However, there was no significant difference in the frequency distribution of the alleles.展开更多
