IMPORTANCE Patients with psoriasis may experience comorbidities involving cardiovascular diseases, chronic kidney disease, uveitis, psychiatric disturbances, and metabolic syndrome. However, the association between psoriasis and inflammatory bowel disease (IBD) has been largely unclear. OBJECTIVE To investigate the association of psoriasis with IBD. DATA SOURCES For this systematic review and meta-analysis, MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched for relevant studies from inception to January 17, 2018. STUDY SELECTION Case-control, cross-sectional, or cohort studies that examined either the odds or risk of IBD in patients with psoriasis were included. No geographic or language limitations were used in the search. DATA EXTRACTION AND SYNTHESIS The PRISMA and MOOSE guidelines were followed for data extraction. The Newcastle-Ottawa Scale was used to evaluate the risk of bias of included studies. Crohn disease and ulcerative colitis were analyzed separately and random-effects model meta-analysis was conducted. A subgroup analysis was performed on psoriatic arthritis. MAIN OUTCOMES AND MEASURES The risk and odds of IBD, Crohn disease, and ulcerative colitis in patients with psoriasis. RESULTS A total of 5 case-control or cross-sectional studies and 4 cohort studies with 7 794 087 study participants were included. Significant associations were found between psoriasis and Crohn disease (odds ratio, 1.70; 95% CI, 1.20-2.40) and between psoriasis and ulcerative colitis (odds ratio, 1.75; 95% CI, 1.49-2.05). Patients with psoriasis had an increased risk of Crohn disease (risk ratio, 2.53; 95% CI, 1.65-3.89) and ulcerative colitis (risk ratio, 1.71; 95% CI, 1.55-1.89). CONCLUSIONS AND RELEVANCE These findings suggest that psoriasis is significantly associated with IBD. Gastroenterology consultation may be indicated when patients with psoriasis present with bowel symptoms.
Purpose: To unravel the role of interleukin (IL)-6 and insulinlike growth factor (IGF)-I receptor (IGFIR) in expressing stemnessrelated properties and to evaluate the prognostic values of pluripotent transcription factor OCT4/NANOG, and IGFIR in hepatocellular carcinoma (HCC).Experimental Design: Serum levels of IL6 were detected using ELISA assays (n ¼ 120). The effects of IL6/IGFI on stemness expression in HCC were examined using OCT4/ NANOG promoter luciferase reporter, RNA interference, secondary sphere formation, side population, and xenograft animal models. The OCT4/NANOG protein and phospho-IGFI receptor (p-IGFIR) in tissues were detected by Western blotting (n ¼ 8) and immunohistochemical staining (n ¼ 85). OCT4, NANOG, and IGFIR expression levels in tissues (n ¼ 191) were analyzed by real-time qRT-PCR and was correlated with early tumor recurrence using the Kaplan-Meier survival analysis.Results: A high positive correlation between the expression levels of OCT4/NANOG and IGFIR/p-IGFIR in human HCC tissues was observed. The concurrent expression of OCT4/ NANOG/IGFIR was mostly confined to hepatitis B virus (HBV)-related HCC (HBV-HCC) and was significantly correlated with early tumor recurrence. High serum levels of IL6 were significantly correlated with high OCT4/NANOG expression. IL6 stimulated an autocrine IGFI/IGFIR expression STAT3 dependently, which stimulated stemness-related properties in both the cell lines and the xenografted mouse tumors. The inhibition of IGFIR activation by either RNA interference or by treatment with the inhibitor picropodophyllin (PPP) significantly suppressed the IL6-induced stemness-related properties both in vitro and in vivo.Conclusions: The expression of pluripotency-related genes is associated with early tumor recurrence and is regulated by IL6-induced IGF/IGFIR activation, particularly in HBV-HCC.
Onset of PG in the first or second trimester and presence of blisters may lead to adverse pregnancy outcomes including decreased gestational age at delivery, preterm birth, and LBW children. Such pregnancies should be considered high risk and appropriate obstetric care should be provided. Systemic corticosteroid treatment, in contrast, does not substantially affect pregnancy outcomes, and its use for PG in pregnant women is justified.
Drug survival of biologics represents their real-world effectiveness and safety. We conducted a meta-analysis of real-world evidence on the drug survival of biologics in treating psoriasis. We searched the PubMed, CENTRAL, and EMBASE databases from inception to 7th October 2017 for studies reporting the annual drug survival for at least 1 year. Two authors independently screened and selected relevant studies, and assessed their risk of bias. A third author was available for arbitrating discrepancies. We conducted a random-effects model meta-analysis to obtain the respective pooled drug survival from year 1 to 4. We conducted subgroup analysis on biologic-naïve subjects, discontinuation for loss of efficacy and adverse effects. We included 37 studies with 32,631 subjects. The drug survival for all biologics decreased with time, dropping from 66% at year 1 to 41% at year 4 for etanercept, from 69% to 47% for adalimumab, from 61% to 42% for infliximab, and from 82% to 56% for ustekinumab. Ustekinumab was associated with the highest drug survival in all and biologic-naïve subjects. Etanercept was associated with the lowest drug survival and was most commonly discontinued for loss of efficacy. Infliximab was most frequently associated with discontinuation for adverse effects. Clinicians may use this study as a reference in treating psoriasis.
IMPORTANCE Hidradenitis suppurativa (HS) and inflammatory bowel disease (IBD) are inflammatory diseases that share common genetic susceptibility and immunologic features. However, the link between HS and IBD has been largely unclear. OBJECTIVE To conduct a meta-analysis to investigate the association between HS and IBD. DATA SOURCES A search of the MEDLINE, Cochrane Central Register of Controlled Trials, and Embase databases yielded 397 relevant studies from inception to June 10, 2018. Two additional studies were supplied by one of the investigators. STUDY SELECTION Case-control, cross-sectional, or cohort studies that examined the odds or risk of IBD in patients with HS were included. No geographic or language limitations were imposed. DATA EXTRACTION AND SYNTHESIS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. The Newcastle-Ottawa Scale was used to assess the risk of bias of included studies. Crohn disease and ulcerative colitis were analyzed separately, and a random-effects model meta-analysis was conducted. MAIN OUTCOMES AND MEASURES The odds ratios (ORs) and hazard ratios (HRs) of IBD, Crohn disease, and ulcerative colitis in association with HS. RESULTS Five case-control studies, 2 cross-sectional studies, and 1 cohort study with a total of 93 601 unique participants were included. The meta-analysis of case-control and cross-sectional studies showed significant associations of HS with Crohn disease (pooled OR, 2.12; 95% CI, 1.46-3.08) and ulcerative colitis (pooled OR, 1.51; 95% CI, 1.25-1.82). Two case-control studies found significant association of HS with IBD (ORs, 2.16 [95% CI, 1.40-3.34] and 10.00 [95% CI, 1.94-51.50]). One cohort study found an increased risk of IBD in patients with HS (HR, 5.6; 95% CI not reported; P < .002). CONCLUSIONS AND RELEVANCE The evidence to date supports an association of HS with IBD. These results suggest that consultation with gastroenterologists should be sought when patients with HS present with recurrent abdominal pain, chronic diarrhea, bloody stool, and body weight loss.
