Background
Vitiligo was an autoimmune disease and some guidelines for the management of vitiligo encouraged the use of NB-UVB combination therapies to enhance repigmentation.Objectives
To compare the effectiveness of current NB-UVB combination regimen at the improvement in repigmentation through a systematic review and network meta-analysis.Methods
We searched the electronic databases for randomized controlled trials related to NB-UVB combination therapy for vitiligo till October 2022. STATA15.0 software was applied to carrying out data analysis.Results
A total of 28 eligible studies involving 1194 participants were enrolled in the analysis. The NMA results revealed that compared with NB-UVB, carboxytherapy [OR = 32.35, 95% CI (1.79, 586.05)], Er: YAG laser+ topical 5% 5-FU [OR = 10.74, 95% CI (4.05, 28.49)], needling/micro-needling [OR = 3.42, 95% CI (1.18, 9.88)], betamethasone intramuscular injection [OR = 3.08, 95% CI (1.17, 8.13)], topical tacrolimus [OR = 2.54, 95% CI (1.30, 4.94)], and oral Chinese herbal medicine compound [OR = 2.51, 95% CI (1.40, 4.50)] integrated with NB-UVB were more efficacious in excellent to complete repigmentation response rate (≥75%). Besides, NB-UVB+ Er: YAG laser+ topical 5% 5-FU [OR = 0.17, 95% CI (0.04, 0.67)] and NB-UVB+ needling/micro-needling [OR = 0.24, 95% CI (0.06, 0.88)] were less likely evaluated as ineffective repigmentation response (≤25%).Conclusions
All combination therapies ranked higher than NB-UVB monotherapy in inducing successful repigmentation and avoiding failed treatment in patients with vitiligo. Comprehensive consideration, NB-UVB+ Er: YAG laser+ topical 5% 5-FU and NB-UVB+ needling/microneedling would be the preferred therapeutic approaches. 相似文献997.

The association of blood pressure (BP) classification defined by the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guideline with cardiometabolic multimorbidity (CMM) remains unclear. The present study aimed to investigate this research gap in the Chinese adults. Cross-sectional data were collected from a population-based cohort conducted in Southern China. Participants were categorized as having normal BP, elevated BP, stage 1 hypertension, and stage 2 hypertension according to the 2017 ACC/AHA guideline. CMM was defined as having two or more of the following diseases: coronary heart disease, stroke, and diabetes. The relationship between the BP classifications and CMM was examined by multivariate logistic regression. A total of 95 649 participants (mean age: 54.3 ± 10.2 years, 60.7% were women) were enrolled in this study. Multivariable-adjusted logistic regression models revealed that stage 1 hypertension (odds ratio [OR], 1.35; 95% confidence interval [CI], 1.03–1.78) and stage 2 hypertension (OR, 3.53; 95% CI, 2.82–4.47) were significantly associated with a higher prevalence of CMM compared with normal BP. The association between stage 1 hypertension and CMM were profound in women (OR, 1.76; 95% CI, 1.17–2.67) and in the middle-aged group (OR, 1.53; 95% CI, 1.02–2.35) compared with men and older individuals, respectively. Our study showed that among Chinese adults, stage 1 hypertension defined by the 2017 ACC/AHA guideline was already associated with higher odds of CMM compared with normal BP, particularly in women and middle-aged participants. Managing stage 1 hypertension may be an important measure to prevent CMM in Chinese adults. 相似文献
