Abstract
Celiac disease (CD) is an autoimmune intestinal disease caused by the intake of gluten-containing cereals and their products by individuals with genetic susceptibility genes. Vitiligo is a commonly acquired depigmentation of the skin; its clinical manifestation are skin patches caused by localized or generalized melanin deficiency. Both diseases have similar global incidence rates (approximately 1%) and are associated to similar diseases, including autoimmune bullous disease, inflammatory bowel disease, autoimmune thyroiditis, autoimmune gastritis, and type 1 diabetes. The relationship between CD and vitiligo has been reported in several studies, but their conclusions are inconsistent. Further, it has also been reported that a gluten-free diet (GFD) can improve the symptoms of immune-related skin diseases such as vitiligo. In this mini-review, we summarize and review the literature on the relationship between CD and vitiligo, assess the therapeutic significance of GFD for patients with vitiligo, and explore their possible physiopathology. We are hopeful that the information summarized here will assist physicians who treat patients with CD or vitiligo, thereby improving the prognosis.

Abstract
Vitiligo is a common immune-related depigmentation condition, and its pathogenesis remains unclear. This study used a combination of bioinformatics methods and expression analysis techniques to explore the relationship between immune cell infiltration and gene expression in vitiligo. Previously reported gene expression microarray data from the skin (GSE53146 and GSE75819) and peripheral blood (GSE80009 and GSE90880) of vitiligo patients and healthy controls was used in the analysis. R software was used to filter the differentially expressed genes (DEGs) in each dataset, and the KOBAS 2.0 server was used to perform functional enrichment analysis. Compared with healthy controls, the upregulated genes in skin lesions and peripheral blood leukocytes of vitiligo patents were highly enriched in immune response pathways and inflammatory response signaling pathways. Immunedeconv software and the EPIC method were used to analyze the expression levels of marker genes to obtain the immune cell population in the samples. In the lesional skin of vitiligo patients, the proportions of macrophages, B cells and NK cells were increased compared with healthy controls. In the peripheral blood of vitiligo patients, CD8+ T cells and macrophages were significantly increased. A coexpression analysis of the cell populations and DEGs showed that differentially expressed immune and inflammation response genes had a strong positive correlation with macrophages. The TLR4 receptor pathway, interferon gamma-mediated signaling pathway and lipopolysaccharide-related pathway were positively correlated with CD4+ T cells. Regarding immune response-related genes, the overexpression of IFITM2, TNFSF10, GZMA, ADAMDEC1, NCF2, ADAR, SIGLEC16, and WIPF2 were related to macrophage abundance, while the overexpression of ICOS, GPR183, RGS1, ILF2 and CD28 were related to CD4+ T cell abundance. GZMA and CXCL10 expression were associated with CD8+ T cell abundance. Regarding inflammatory response-related genes, the overexpression of CEBPB, ADAM8, CXCR3, and TNIP3 promoted macrophage infiltration. Only ADORA1 expression was associated with CD4+ T cell infiltration. ADAM8 and CXCL10 expression were associated with CD8+ T cell abundance. The overexpression of CCL18, CXCL10, FOS, NLRC4, LY96, HCK, MYD88, and KLRG1, which are related to inflammation and immune responses, were associated with macrophage abundance. We also found that immune cells infiltration in vitiligo was associated with antigen presentation-related genes expression. The genes and pathways identified in this study may point to new directions for vitiligo treatment.

Abstract
BACKGROUND Pioglitazone may be beneficial in the treatment of psoriasis. However, based on the effectiveness and safety considerations, it has not been widely used. To fully evaluate the strength of evidence supporting psoriasis treatment with pioglitazone, we conducted a meta-analysis of existing published studies. METHODS PubMed, Ovid, Cochrane Library, Google Scholar, and Web of Science databases were systematically searched before February 2019. Randomized controlled trials (RCTs) of pioglitazone administration compared with placebo, administered to patients with psoriasis for at least 10 weeks, and published in English were included. Quality of the included RCTs was identified by the modified Jadad scale. The quality of evidence for each outcome was evaluated using the GRADEpro Guideline Development Tool online software. Primary outcomes were proportion of patients showing psoriasis area and severity index (PASI) score improvement (>75%) and the mean percent change in PASI score from baseline to the end of treatment. Dichotomous data were analyzed using odds ratios (ORs) corresponding to the 95% confidence interval (CI), whereas continuous variables, expressed as mean and standard deviation, were analyzed using the mean differences (MD) with the 95% CI. RESULTS Six RCTs were analyzed. Meta-analysis showed that pioglitazone reduced the PASI scores in patients with psoriasis compared with the control group when administered at 30 mg per day (P < 0.001, MD = -3.82, 95% CI = -5.70, -1.93) and at 15 mg per day (P = 0.04, MD = -3.53, 95% CI = -6.86, -0.20). The PASI-75 of the pioglitazone group was significantly higher than that of the control group at 30 mg per day (P < 0.001, OR = 8.30, 95% CI = 3.99, 17.27) and at 15 mg per day (P = 0.03, OR = 2.96, 95% CI = 1.08, 8.06). No statistically significant differences in total adverse events were observed between the groups. There were no significant differences in common adverse reactions such as weight gain and elevated liver enzymes between the two pioglitazone groups. CONCLUSIONS Use of pioglitazone in the current treatment of psoriasis is beneficial. The therapeutic effect of the daily 30 mg dose may be greater than that of the 15 mg dose per day with no significant change in the frequency of adverse reactions.

Abstract
BACKGROUND Gastric Helicobacter pylori (H. pylori) infection is related to chronic gastritis, gastroduodenal ulcer, and gastric malignancies; whether this infection is related to colorectal polyps and colorectal cancer (CRC), remains debatable.
AIM To investigate the relationship between gastric H. pylori infection and the risk of colorectal polyps and CRC.
METHODS We retrospectively analyzed 3872 patients with colorectal polyps who underwent colonoscopy and pathological diagnosis. We also analyzed 304 patients with primary CRC. The characteristics of these patients were compared with those of the control group, which included 2362 patients with the normal intestinal mucosa. All subjects completed a 14C-urea breath test, bidirectional gastrointestinal endoscopy, and a biopsy on the same day. Data on the number, size, location, and pathology of the polyps, the location, and pathology of the CRC, the detection of H. pylori, and the incidence of H. pylori-associated atrophic gastritis or intestinal metaplasia were obtained. A logistic regression model was used to analyze the relationship between gastric infection due to H. pylori, and the incidence of colorectal polyps and CRC.
RESULTS The prevalence of H. pylori infection was higher in the multiple polyps group than in the solitary polyp group and the control group [95% confidence interval (CI) = 1.02-1.31, P = 0.03; 95%CI: 2.12-2.74, P < 0.001]. The patients with adenomatous polyps had a higher incidence of H. pylori infection than patients with non-adenomatous polyps [59.95% vs 51.75%, adjusted odds ratio (OR) = 1.41, 95%CI: 1.24-1.60, P < 0.01]. Patients with H. pylori-associated atrophic gastritis or intestinal metaplasia were at high risk of CRC (adjusted OR = 3.46, 95%CI: 2.63-4.55, P < 0.01; adjusted OR = 4.86, 95%CI: 3.22-7.34, P < 0.01, respectively). The size and location of the polyps, the histopathological characteristics and the location of CRC were not related to H. pylori infection.
CONCLUSION Our study demonstrates that the incidence of gastric H. pylori infection and H. pylori-associated atrophic gastritis or intestinal metaplasia elevates the risk of colorectal polyps and CRC.

Abstract
BACKGROUND Colorectal cancer is a common malignant tumor of the digestive tract. The relationship between sentinel polyps (rectal polyps with proximal colon cancer) and proximal colon cancer has received extensive attention in recent years. However, there is still no clear conclusion regarding the relationship.
AIM To investigate the clinical characteristics of sentinel polyps and their correlation with proximal colon cancer.
METHODS A retrospective analysis of 2587 patients with rectal polyps from January 2006 to December 2017 was performed. According to whether or not proximal colon cancer was diagnosed, the patients were divided into either a sentinel polyp group (192 patients) or a pure rectal polyp group (2395 patients). The endoscopic features, clinicopathological features, therapeutic effects, and short-term prognosis were analyzed and compared between the two groups.
RESULTS The mean age of patients in the sentinel polyp group was generally higher than that of the pure rectal polyp group, and the positivity rates of anemia, stool occult blood, and tumor markers of the sentinel polyp group were also significantly higher than those in the rectal polyp group (χ2 = 90.56, P < 0.01; χ2 = 70.30, P < 0.01; χ2 = 92.80, P < 0.01). The majority of the patients in the sentinel polyp group had multiple polyps, large polyps, adenomatous polyps, or sessile polyps (χ2 = 195.96, P < 0.01; χ2 = 460.46, P < 0.01; χ2 = 94.69, P < 0.01; χ2 = 48.01, P < 0.01). Most of the proximal colon cancers were Duke’s A and B stages in the sentinel polyp group. In the pure rectal polyp group, 2203 patients underwent endoscopic treatment, and all of the patients were cured and discharged. In the sentinel polyp group, 65 patients underwent radical operation, and 61 patients received endoscopic submucosal dissection or endoscopic mucosal resection. Additionally, 21 patients were lost to follow-up after 6-12 mo, and the loss rate was 10.94%. A total of 63.16% of patients experienced remission without tumor recurrence or metastasis, 33.33% of patients experienced tumors regression or improved symptoms, and the other 3.51% of the patients died.
CONCLUSION If there are multiple, sessile, and adenomatous rectal polyps with a maximum diameter > 1 cm, the possibility of the carcinogenesis of the polyps or of the proximal colon should be monitored closely. These patients should be followed in the short-term and should undergo a whole-colon examination.

Abstract
OBJECTIVES To explore the relationship among the vitamin D receptor (VDR) gene polymorphisms, serum 25-hydroxyvitamin D levels, and vitiligo. METHODS Databases including PubMed, Cochrane Library, Ovid, Web of Science, CNKI, SinoMed, and Wanfang Data were systematically searched. The association was assessed using odds ratios (ORs), standard mean difference (SMD), and 95% confidence intervals (CIs). The statistical tests were performed using Review Manager 5.3.3. RESULTS We identified a total of 17 studies. The relationship between VDR gene polymorphisms (BsmI, ApaI, TaqI, and FokI), serum 25 (OH)D levels, and incidence of vitiligo was investigated. The results of this meta-analysis showed that the dominant genetic model (CC+AC vs AA, P = .007, OR = 1.41, 95% CI = 1.10-1.80), recessive genetic model (CC vs AC+AA, P = .01, OR = 4.10, 95% CI = 1.36-12.35), and allelic contrast model (C vs A, P = .005, OR = 1.87, 95% CI = 1.21-2.90) of VDR Apal locus increased the risk of vitiligo, and BsmI, TaqI, and FokI loci and the risk of vitiligo have no obvious correlation. Serum 25 (OH)D deficiency was positively associated with the incidence of vitiligo (P < .0001, SMD = -0.94, 95% CI = -1.39, -0.48). CONCLUSION This meta-analysis revealed that VDR Apal polymorphism increased the susceptibility risk of vitiligo, and there is a positive correlation between serum 25 (OH)D deficiency and the incidence of vitiligo.
