IL-23/IL-17 axis has been identified as major factor involved in the pathogenesis of several autoimmune diseases; yet its pathogenetic role in pemphigus vulgaris (PV) remains controversial. The aim of this research was to investigate the potential role of IL-23/IL-17 axis in the immunopathogenesis of PV, and correlation between IL-23+ cells and IL-17+ cells was also evaluated. For this purpose, ten patients with PV, three patients with pemphigus foliaceus (PF), and six healthy individuals were allocated to this research. The lesional skin biopsy specimens were obtained before treatment. Then immunofluorescence staining was performed to analyze the expression of IL-23 and IL-17 in the PV/PF patients and the healthy individuals. The results showed that the numbers of IL-23+ and IL-17+ cells were significantly higher in PV lesions, compared to PF lesions and normal control skins, respectively (all P < 0.05). Moreover, the correlation between IL-23+ cells and IL-17+ cells was significant (r = 0.7546; P < 0.05). Taken together, our results provided evidence that the IL-23/IL-17 axis may play a crucial role in the immunopathogenesis of PV and may serve as novel therapeutic target for PV.
BackgroundThere is no existing report on the quality of randomized controlled trials (RCTs) of melasma treatment currently conducted in China. This study aims to assess the quality of RCT- reporting in the treatment of melasma conducted in China.MethodsSeveral databases were searched from their inception through to August 2014. In order to rate the report quality, we scored 1 for the item if it was reported in CONSORT 2010 and 0 for the item if it was not definitely stated or was not clear. For overall quality score (OQS), 13 items were scored and calculated with a range of 0 to 13. Five items (‘randomization’, ‘allocation concealment’, ‘blinding’, ‘baseline characteristics’ and ‘intention-to-treat (ITT) analysis’) were scored and a key methodological index score (MIS) was calculated with a range of 0 to 5 for each trial.ResultsA total of 246 relevant RCTs were included in the final analysis. The median OQS was 7, with a minimum of 4 and a maximum of 11. Some items’ information was insufficient, especially in the categories of ‘trial design’, ‘sample size’, ‘recruitment’ and ‘ancillary analyses’ with a positive rate of less than 20%. The median MIS was 1 with a minimum of 0 and a maximum of 3. Some items’ reporting was poor, especially in the categories of ‘randomization’, ‘allocation concealment and implementation’, ‘blinding’ and ‘ITT analysis’ with a positive rate of less than 10%. The mean OQS increased by about 0.52 for manuscripts published in the period of 5-year increments (95% CI: 0.32 to 0.72; P < 0.001). With regard to the MIS, no variable was statistically significant in the ordinal regression model.ConclusionThe reporting quality of RCTs in the treatment of melasma conducted in China is not satisfactory especially in key methodological items. Reporting of RCTs in this field should meet and keep up with the standards of the CONSORT statement.Electronic supplementary materialThe online version of this article (doi:10.1186/s13063-015-0677-2) contains supplementary material, which is available to authorized users.
Objective Hairline vitiligo is a special area. Hairy areas within the hairline often require repigmentation and regrowing hair shafts. The face and forehead outside the hairline do not require regrowing hair shafts, only repigmentation. To tackle this issue, we modified the conventional mini-punch grafting with a combined application of mini-punch grafting and follicular hair transplant. Methods Five patients with localized hairline stable vitiligo aged 26–32 years old had a history of nonsurgical treatments for at least 3 months and without progress. The grafts were transversely sectioned. The intact half follicles were preserved below the cross-section. Sectioned grafts were placed into the chambers for transplanting with forceps. Results The treatment using transversely sectioned mini-punch grafting with the patient was performed for all five patients, and the results were satisfactory. In the area of the forehead outside the hairline with the sectioned mini-punch grafting above the cross-section, hair loss and repigmentation were observed. In the area of the hairy areas within the hairline, growing hair shafts and repigmentation were observed, without hair loss. Conclusion Our report can help to manage hairline vitiligo or hairy areas vitiligo. This method can be considered a potential method for the treatment of hairline vitiligo, thus providing a simple solution to complex problems.
