Periostin may play a critical role in disease severity and chronicity in the pathogenesis of AD.

A double-blind, multi-center study was performed on patients with HTLV-I-associated myelopathy (HAM) to evaluate the therapeutic effect of treatment with natural interferon-alpha (HLBI). Forty-eight HAM patients were enrolled and treated with either 0.3 MU (n = 15), 1.0 MU (n = 17), or 3.0 MU (n = 16) of HLBI for 28 days. Clinical evaluation included motor dysfunction, urinary disturbances, and changes of neurologic signs. The frequency of therapeutic response judged as excellent to good 4 weeks after starting therapy and 4 weeks after completion of therapy were 7.1% (1 of 14) and 8.3% (1 of 12) in the 0.3-MU group, 23.5% (4 of 17) and 26.7% (4 of 15) for the 1.0-MU group, and 66.7% (10 of 15) and 61.5% (8 of 13) for the 3.0-MU group. The therapeutic benefit in the 3.0-MU group was significantly higher than in the 0.3-MU group. There was no significant difference in the incidence of symptomatic side effects between groups. Abnormal laboratory data were obtained for some patients in the 1.0-MU and 3.0-MU groups; however, the treatment schedule could be continued in most patients. These results suggest that HAM patients may be safely treated with HLBI 3.0 MU every day for 4 weeks with favorable clinical effects.

Drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms (DIHS/DRESS) is a severe adverse drug reaction caused by specific drug. It is characterized by visceral organ involvement and reactivation of various human herpesviruses. Although sporadic reports have documented certain conditions that appear after the resolution of DIHS/DRESS, little information is available on sequelae after resolution of DIHS/ DRESS in a large patient population. The Asian Research Committee on Severe Cutaneous Adverse Reactions, comprised of doctors from Japan and Taiwan, conducted a survey on sequelae and deterioration of the underlying disease in patients with DIHS/DRESS. This was achieved by directly interviewing patients who had been followed-up by experts or through a questionnaire mailed to patients. Questions were asked about new onset cardiovascular disease, collagen disease or autoimmune disease, gastrointestinal disease, renal disease, respiratory disease, neoplasms, and other diseases such as herpes zoster and diabetes mellitus, as well as deterioration of the underlying disease. A total of 145 patients were analyzed in this study. The following newly developed diseases after recovery from DIHS/DRESS were observed: Graves' disease (n = 2), Hashimoto's disease (n = 3), painless thyroiditis (n = 2), fulminant type 1 diabetes mellitus (n = 5), and infectious diseases (n = 7). Several DIHS/ DRESS patients with pre-existing renal dysfunction required lifelong hemodialysis. DIHS/DRESS is a condition that increases the risk of new onset of disease. Long-term observation of DIHS/DRESS can provide an opportunity to investigate substantial diseases from onset to the full-blown stage. Patients with DIHS/DRESS require careful long-term follow-up.

Treatment with steroid pulse therapy in combination with plasmapheresis and/or immunoglobulin therapy seems to have contributed to prognostic improvement in SJS/TEN.
