OBJECTIVE: To determine if the prevalence of autoimmunity among relatives of patients with juvenile rheumatoid arthritis (JRA) is greater than that among relatives of healthy volunteer control subjects. METHODS: Interviews were used to obtain histories of the following disorders among living first- and second-degree relatives of 110 patients and 45 controls: alopecia areata, ankylosing spondylitis, dermatomyositis, Graves' disease, Hashimoto thyroiditis, insulin-dependent diabetes mellitus, inflammatory bowel disease, iritis, JRA, multiple sclerosis, psoriasis, RA, systemic lupus erythematosus, and vitiligo. Chi-squares, odds ratios (ORs), and 95% confidence intervals (95% CIs) were calculated. Families of 23 JRA affected sibpairs were interviewed subsequently. RESULTS: There were no significant differences between patients and controls with regard to age, sex, ethnicity, or family size. Patients had 1,228 relatives and controls had 496 relatives. Of all the relatives of the patients, 155 had at least 1 autoimmune disorder, compared with 20 relatives of the controls (12.6% versus 4.0%; OR 3.4 [95% CI 2.1-5.7], P < 0.000001). The prevalence of autoimmunity was increased in first-degree and in second-degree relatives of patients (16.1% and 10.6%, respectively). The prevalence of Hashimoto thyroiditis was significantly higher in the relatives of patients (OR 3.5 [95% CI 1.6-7.9], P = 0.0008). The prevalences of other disorders were not significantly different. JRA affected sibpair families had an increased prevalence of autoimmunity (15.0%). A history of arthritis was found significantly more frequently in the JRA affected sibpair families, but not in the simplex families. CONCLUSION: These data demonstrate that the prevalence of autoimmunity is significantly higher among first- and second-degree relatives of JRA patients. This suggests that clinically different autoimmune phenotypes may share common susceptibility genes, which may act as risk factors for autoimmunity.

Alopecia areata has been reported to be accompanied by abnormal autoimmune dysfunction. We examined the expression of cutaneous lymphocyte-associated antigen (CLA), which is a skin-specific lymphocyte homing receptor, in the peripheral blood lymphocytes and skin of patients with alopecia areata. In the patients' peripheral blood, the percentage of CLA-positive CD4+ or CD8+ lymphocytes, was significantly higher than that of normal controls. The patients with severe or progressive alopecia areata showed a much higher CLA-positivity compared to patients recovering from the disease. A chronological study showed that the percentage of CLA-positive peripheral blood lymphocytes, CD4 + or CD8 + lymphocytes decreased in parallel with the patients' good clinical course. The CLA-positivity in peripheral blood lymphocytes, CD4+ or CD8+ lymphocytes of patients with alopecia areata who did not respond to oral corticosteroid therapy remained higher than in those who responded well to the treatment. In the affected scalp skin, many infiltrating lymphocytes around the hair follicles, which were CD4+ or CD8+ lymphocytes, expressed CLA. These findings suggest that the CLA-positivity correlates with clinical activity and that CLA-positive CD4+ or CD8+ lymphocytes may play an important role in alopecia areata.

[Kossard frontal fibrosing alopecia in a man]

In 1994 Steven Kossard described a new and peculiar type of hair loss that he named postmenopausal frontal fibrosing alopecia. In 6 elderly women he observed a symmetric regression of the frontal hair line. Often the eyebrows were also affected. Histology showed lichen planopilaris. There were no clinical signs of lichen planus on the rest of the body. Since the original description by Kossard, several cases of frontal fibrosing alopecia have been described--almost all of them in elderly women. We report a man with frontal fibrosing alopecia of the Kossard type.

Hair growth is a sophisticated biological process, which is still not thoroughly understood. A multitude of therapeutic measures, including drugs, surgery, and suppelements have been made available, and used. However, due to the diversity of the problems underlying hair loss, there is no single solution for all hair loss cases. Most of chemical drugs and hair transplantation surgeries are not free from varying degrees of undesirable side effects on health.
We only know by anecdotal observations. There has been no clinical trials nor placebo controlled statistical analysis on the efficacy of Hair Million on hair loss and hair growth.

DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones)
or estrogens (female hormones) in the cells.
