Impact of Jumihaidokuto (Shi-Wei-Bai-Du-Tang) on Treatment of Chronic Spontaneous Urticaria: A Randomized Controlled Study / 中国结合医学杂志

OBJECTIVE@#To study the effect of Jumihaidokuto (Shi-Wei-Bai-Du-Tang, ) in the management of chronic spontaneous urticaria.@*METHODS@#A randomized two-arm, parallel group study was conducted to compare the effect of Jumihaidokuto (6 g daily) with a control for 8 weeks. Concomitant therapy (e.g., antihistamines) was continued. Twenty-one subjects with severe chronic urticaria were enrolled in this study. The primary treatment outcome was the severity score proposed by the Japanese Dermatological Association. Secondary outcomes were quality of life (Skindex-16), itch intensity (Visual Analogue Scale), and patients' subjective disability due to wheal or itch. After the subjects were randomly assigned to groups by block randomization, 10 received Jumihaidokuto, and 11 did not. All subjects had already taken antihistamines.@*RESULTS@#Improvement was significant when comparing the severity score of the Jumihaidokuto group with that of the control group (P<0.01). Skindex-16 values for both groups gradually decreased in the same fashion.@*CONCLUSION@#Concomitant use of Jumihaidokuto with antihistamine was more effective than antihistamine alone in the management of chronic idiopathic urticaria.

Immunohistochemical Analysis of Interleukin-17 Producing T Helper Cells and Regulatory T Cells Infiltration in Annular Erythema Associated with Sjogren's Syndrome

BACKGROUND: Peculiar erythema known as annular erythema associated with Sjogren's syndrome (AESS) can be differentiated from autoimmune annular erythema and subacute cutaneous lupus erythematosus, both clinically and histologically. However, there are no detailed investigations on immune competent cells infiltration. OBJECTIVE: Preferential infiltration of interleukin-17-producing T helper (Th17) cells and regulatory T (Treg) cells into the labial salivary gland is reported to play a role in maintaining mucoepithelitis in patients with Sjogren's syndrome. In this study, we evaluated Th17 and Treg cell infiltration into the lesional skin of AESS. METHODS: We analyzed the numbers and infiltration patterns of Th17 and FoxP3 (+) Treg cells in seven cases of AESS using immunohistochemistry. Seven patients with systemic lupus erythematosus (SLE), atopic dermatitis (AD) and psoriasis vulgaris (PV), which are representatives of Th17 cell-involved skin disorders, were enrolled as disease controls. RESULTS: Periappendageal and epidermal changes, such as follicular plugging and liquefaction, were evident in the annular erythema of SLE, not AESS, tissue samples. In AESS tissue samples, dense perivascular and periappendageal infiltration of lymph cells was observed in the middle-to-deep dermis, as previously described, in contrast to the superficial infiltration pattern observed in both AD and PV samples. While the total number of infiltrated lymphocytes was similar between AESS and SLE tissue samples, Th17 cells were found to be preferentially infiltrated in the middle-to-deep dermis in AESS samples. CONCLUSION: These results suggest that an increased number and distribution of infiltration of Th17 cells is a preferential feature of AESS, rather than a characteristic feature of annular erythema of SLE.

Morphea on the Breast after a Needle Biopsy

Localized scleroderma (morphea) usually develops spontaneously, but the precise mechanisms underlying disease development are obscure. However, a significant number of cases suggest that morphea is induced by external stimuli. Herein, we report a case of morphea that developed after a needle biopsy.
