BACKGROUND: Defective cell-mediated immunity increases the risk of human papillomavirus-associated anal dysplasia and cancer. There is limited information on anal canal disease in patients with IBD. OBJECTIVE: The purpose of this study was to assess anal/vaginal human papillomavirus and anal dysplasia prevalence in patients with IBD. DESIGN: Patients had an anal examination before routine colonoscopy. SETTINGS: The study was conducted at a tertiary IBD referral center. PATIENTS: We studied a convenience sample of sexually active male and female patients with IBD who were not on biological therapy. INTERVENTION: Anal examination, anal and vaginal human papillomavirus testing, anal cytology, and high-resolution anoscopy/biopsy were carried out. MAIN OUTCOME MEASURES: Anal and vaginal human papillomavirus types, anal cytology, and biopsy grade were measured. RESULTS: Twenty-five male and 21 female evaluable participants, 31 with Crohn's disease, 14 with ulcerative colitis, and 1 with indeterminate colitis, were predominantly white (91.3%), treatment experienced (76.1%), an average age of 38.1 years (range, 22.0-66.0 y), and had an average length of IBD diagnosis of 9.3 years (range, 1.0-33.0 y). Eighteen (39.1%) had an abnormal perianal examination and 3 (6.5%) had an abnormal digital examination. Forty-one (89.1%) had anal human papillomavirus, 16 with a single type and 25 with multiple types (range, 2-5 types). Human papillomavirus type 16 was most common (65.2%), followed by human papillomavirus types 11 and 45 (37.0% each). Nineteen of 21 (90.5%) women had vaginal human papillomavirus. Overall, 21 (45.7%) had abnormal anal cytology. Thirty three (71.7%) had ≥1 anal biopsy (9 had multiple), with dysplasia diagnosed in 28 (60.9%) and high-grade and low-grade squamous intraepithelial lesions diagnosed in 4 (8.7%) and 24 (43.5%). LIMITATIONS: No control group was included, and no detailed sexual history was taken. CONCLUSIONS: A high prevalence of anal and vaginal human papillomavirus and anal dysplasia was demonstrated in the study population outcomes. See Video Abstract at

BACKGROUND: Inflammatory bowel disease (IBD) is a chronic disease placing a large health and economic burden on health systems worldwide. The treatment landscape is complex with multiple strategies to induce and maintain remission while avoiding long-term complications. The extent to which rising treatment costs, due to expensive biologic agents, are offset by improved outcomes and fewer hospitalisations and surgeries needs to be evaluated. This systematic review aimed to assess the cost-effectiveness of treatment strategies for IBD. MATERIALS AND METHODS: A systematic literature search was performed in March 2017 to identify economic evaluations of pharmacological and surgical interventions, for adults diagnosed with Crohn's disease (CD) or ulcerative colitis (UC). Costs and incremental cost-effectiveness ratios (ICERs) were adjusted to reflect 2015 purchasing power parity (PPP). Risk of bias assessments and a narrative synthesis of individual study findings are presented. RESULTS: Forty-nine articles were included; 24 on CD and 25 on UC. Infliximab and adalimumab induction and maintenance treatments were cost-effective compared to standard care in patients with moderate or severe CD; however, in patients with conventional-drug refractory CD, fistulising CD and for maintenance of surgically-induced remission ICERs were above acceptable cost-effectiveness thresholds. In mild UC, induction of remission using high dose mesalazine was dominant compared to standard dose. In UC refractory to conventional treatments, infliximab and adalimumab induction and maintenance treatment were not cost-effective compared to standard care; however, ICERs for treatment with vedolizumab and surgery were favourable. CONCLUSIONS: We found that, in general, while biologic agents helped improve outcomes, they incurred high costs and therefore were not cost-effective, particularly for use as maintenance therapy. The cost-effectiveness of biologic agents may improve as market prices fall and with the introduction of biosimilars. Future research should identify optimal treatment strategies reflecting routine clinical practice, incorporate indirect costs and evaluate lifetime costs and benefits.

BACKGROUND: Detection of human herpesviruses (HHVs) other than cytomegalovirus (CMV) in colonic mucosa of individuals with inflammatory bowel disease (IBD) remains unknown. This study identified eight HHVs in the colonic mucosa of individuals with IBD and compared the results with immunocompetent and human immunodeficiency virus (HIV)-infected individuals. METHODS: A total of 89 individuals who had colorectal ulcer on colonoscopy were enrolled: 26 with immunocompetency (n = 26), 41 with IBD, and 22 with HIV infection. We examined the colonic ulcers for the presence of eight HHVs-herpes simplex virus (HSV)-1/2, varicella zoster virus (VZV), CMV, Epstein-Barr virus (EBV), HHV-6, HHV-7, and HHV-8-using mucosal PCR. RESULTS: The IBD group had positivity rates of 0%, 0%, 0%, 53.7%, 24.4%, 39%, 39%, and 0% for HSV-1, HSV-2, VZV, EBV, CMV, HHV-6, HHV-7, and HHV-8, respectively. The positivity rates of EBV and CMV in colonic mucosa increased significantly in the order of the immunocompetent, IBD, and HIV groups (EBV: 23.1%, 53.7%, 72.7%, P for trend = 0.0005; CMV, 7.7%, 24.4%, 54.5%, P for trend = 0.0003, respectively), but no increase was found in the other HHVs. Median mucosal EBV DNA values in the immunocompetent, IBD, and HIV groups were 0, 76, and 287 copies/μg DNA, respectively (P for trend = 0.002). Corresponding median mucosal CMV DNA values were 0, 0, and 17 copies/μg DNA (P for trend = 0.0001). There was no significant difference in the positivity rates of the eight HHVs between ulcerative colitis and Crohn's disease. CONCLUSION: The HHVs of EBV, CMV, HHV-6, and HHV-7, but not of HSV-1, HSV-2, VZV, or HHV-8, were identified in the colonic mucosa of IBD individuals. EBV and CMV in colonic mucosa was correlated with host immune status in increasing order of immunocompetent, IBD, and HIV-infected individuals.

OBJECTIVE: To determine whether REM sleep behavior disorder (RBD) in Parkinson disease (PD) is associated with lesions and dysfunctions of the autonomic nervous system by evaluating enteric phosphorylated α-synuclein histopathology (PASH) and permeability. METHODS: A total of 45 patients with PD were included in this cross-sectional study. RBD was diagnosed on the basis of a standardized clinical interview and confirmed by polysomnography. For each patient, 5 biopsies were taken at the junction between the sigmoid and descending colon during the course of a rectosigmoidoscopy. For the detection of enteric PASH, 2 colonic biopsies were analyzed by immunohistochemistry with antibodies against phosphorylated α-synuclein and PGP9.5 in 43 patients (2 patients were excluded because only 1 biopsy was available). The paracellular permeability and transcellular permeability were evaluated by measuring sulfonic acid and horseradish peroxidase flux, respectively, in the 3 remaining biopsies mounted in Ussing chambers. RESULTS: Enteric PASH was more frequent in the subgroup of patients with PD with RBD compared to patients without RBD (18 of 28, 64.3%, vs 2 of 15, 13.3%, respectively, p < 0.01). No differences were observed in intestinal permeability between patients with PD with and without RBD. CONCLUSIONS: Patients with PD and RBD have a greater frequency of synuclein pathology in the enteric nervous system, suggesting that RBD is associated with widespread synuclein neuropathology.

OBJECTIVE: To estimate effects of gastric tube (G-tube) on survival and quality of life (QOL) in people with amyotrophic lateral sclerosis (ALS) correcting for confounding by indication inherent in nonrandomized observational data. METHODS: To complement a recent causal inference analysis, which concluded that G-tube placement increases the hazard of death, permanent assisted ventilation, or tracheostomy by 28%, we fit causal inference models on a different sample of 481 patients with ALS enrolled in a recent clinical trial of ceftriaxone. Forward selection identified predictors of G-tube placement. Effects of G-tube on survival and QOL were estimated using structural nested models and marginal structural models, accounting for predictors of G-tube treatment. RESULTS: Forced vital capacity and the total score and bulbar subscale of the revised ALS Functional Rating Scale best predicted G-tube placement. Correcting for these confounders, G-tube placement decreased survival time by 46% (p < 0.001) and had no effect on QOL (p = 0.078). Sensitivity survival analyses varied in significance, but none revealed a survival benefit. CONCLUSIONS: In the absence of randomization, causal inference methods are necessary to correct for time-varying confounding. G-tube placement may have a negative effect on survival with no QOL-related benefit for people with ALS. A randomized controlled trial is warranted to further evaluate the efficacy of this widely used intervention. CLINICALTRIALSGOV IDENTIFIER: NCT00349622. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that for patients with ALS, G-tube placement decreases survival time and does not affect QOL.

Before the 2010 devastating earthquake and cholera outbreak, Haiti's public health laboratory systems were weak and services were limited. There was no national laboratory strategic plan and only minimal coordination across the laboratory network. Laboratory capacity was further weakened by the destruction of over 25 laboratories and testing sites at the departmental and peripheral levels and the loss of life among the laboratory health-care workers. However, since 2010, tremendous progress has been made in building stronger laboratory infrastructure and training a qualified public health laboratory workforce across the country, allowing for decentralization of access to quality-assured services. Major achievements include development and implementation of a national laboratory strategic plan with a formalized and strengthened laboratory network; introduction of automation of testing to ensure better quality of results and diversify the menu of tests to effectively respond to outbreaks; expansion of molecular testing for tuberculosis, human immunodeficiency virus, malaria, diarrheal and respiratory diseases; establishment of laboratory-based surveillance of epidemic-prone diseases; and improvement of the overall quality of testing. Nonetheless, the progress and gains made remain fragile and require the full ownership and continuous investment from the Haitian government to sustain these successes and achievements.

RATIONALE: Acute colonic diverticulitis is a well-known surgical emergency, which occurs in about 10 percent of patients known for diverticulosis. PATIENT CONCERNS: The case of a 77-year-old woman is reported, with past history of abdominoperineal resection with end-colostomy for low rectal adenocarcinoma, and who developed an acute colonic diverticulitis in a subcutaneous portion of colostomy with parastomal phlegmon. DIAGNOSES: Initial computed tomography imaging demonstrated a significant submucosal parietal edema with local fat tissues infiltration in regard of 3 diverticula. INTERVENTIONS: A two-step treatment was decided: first a nonoperative treatment was initiated with 2 weeks antibiotics administration, followed by, 6 weeks after, a segmental resection of the terminal portion of the colon with redo of a new colostomy by direct open approach. OUTCOMES: Patient was discharged on the second postoperative day without complications. Follow-up at 2 weeks revealed centimetric dehiscence of the stoma, which was managed conservatively until sixth postoperative week by stomatherapists. LESSONS SUBSECTIONS: Treatment of acute diverticulitis with parastomal phlegmon in a patient with end-colostomy could primary be nonoperative. Delayed surgical treatment with segmental colonic resection was proposed to avoid recurrence and potential associated complications.

BACKGROUND: Diverticulitis in patients with cirrhosis has been associated with higher surgical mortality, but no prior studies evaluate non-surgical treatment results. AIMS: Our aim was to compare the outcomes of hospitalization for diverticulitis in patients with and without cirrhosis. METHODS: We utilized the Nationwide Inpatient Sample (2007-2013) for patients with and without cirrhosis hospitalized for diverticulitis. Patients were further stratified by the presence of compensated versus decompensated cirrhosis. Validated ICD-9 codes captured patients and surgical procedures. Multivariate logistic regression models were fit. The primary outcomes of interest were mortality and surgical intervention rates. RESULTS: There were 1,555,469 patients hospitalized for diverticulitis without cirrhosis, and 7523 patients hospitalized for diverticulitis with cirrhosis. On multivariate analysis, patients with cirrhosis had an increased mortality rate (OR 2.28; 95% CI 1.48-3.5). There were no significant differences in surgical interventions. Subgroup multivariate analyses of compensated cirrhosis (n = 6170) and decompensated cirrhosis (n = 1353) revealed that decompensated cirrhosis had an increased mortality rate (OR 4.99; 95% CI 2.48-10.03) when compared to patients without cirrhosis, whereas those with compensated cirrhosis did not (OR 1.67; 95% CI 0.96-2.91). Those with compensated cirrhosis underwent less surgical interventions (OR 0.82; 95% CI 0.67-0.99) compared to those without cirrhosis. Patients with diverticulitis and cirrhosis had increased costs and lengths of hospitalization. CONCLUSION: Presence of cirrhosis in patients hospitalized for diverticulitis is associated with an increased mortality rate. These are novel findings, and future clinical studies should focus on improving diverticulitis outcomes in this group.

Several conditions associated with reduced gastric acid secretion confer an altered risk of developing a gastric malignancy. Helicobacter pylori-induced atrophic gastritis predisposes to gastric adenocarcinoma, autoimmune atrophic gastritis is a precursor of type I gastric neuroendocrine tumours, whereas proton pump inhibitor (PPI) use does not affect stomach cancer risk. We hypothesised that each of these conditions was associated with specific alterations in the gastric microbiota and that this influenced subsequent tumour risk. 95 patients (in groups representing normal stomach, PPI treated, H. pylori gastritis, H. pylori-induced atrophic gastritis and autoimmune atrophic gastritis) were selected from a cohort of 1400. RNA extracted from gastric corpus biopsies was analysed using 16S rRNA sequencing (MiSeq). Samples from normal stomachs and patients treated with PPIs demonstrated similarly high microbial diversity. Patients with autoimmune atrophic gastritis also exhibited relatively high microbial diversity, but with samples dominated by Streptococcus. H. pylori colonisation was associated with decreased microbial diversity and reduced complexity of co-occurrence networks. H. pylori-induced atrophic gastritis resulted in lower bacterial abundances and diversity, whereas autoimmune atrophic gastritis resulted in greater bacterial abundance and equally high diversity compared to normal stomachs. Pathway analysis suggested that glucose-6-phospahte1-dehydrogenase and D-lactate dehydrogenase were over represented in H. pylori-induced atrophic gastritis versus autoimmune atrophic gastritis, and that both these groups showed increases in fumarate reductase. Autoimmune and H. pylori-induced atrophic gastritis were associated with different gastric microbial profiles. PPI treated patients showed relatively few alterations in the gastric microbiota compared to healthy subjects.

BACKGROUND: Helicobacter pylori (HP) infection and chronic atrophic gastritis (CAG) have shown strong associations with the development of gastric cancer. This study aimed to examine whether both risk factors are associated with accelerated epigenetic ageing, as determined by the 'DNA methylation age', in a population-based study of older adults (n=1477). METHODS: Serological measurements of HP antibodies and pepsinogen I and II for CAG definition were obtained by ELISA kits. Whole blood DNA methylation profiles were measured by Illumina Human Methylation450K Beadchip. DNA methylation ages were calculated by two algorithms proposed by Horvath and Hannum et al. RESULTS: After adjusting for potential covariates in linear regression models, we found that HP infection, infection with virulent HP strains (CagA+) and severe CAG were significantly associated with an increase in DNA methylation age by ∼0.4, 0.6 and 1 year (all P-values <0.05), respectively. CONCLUSIONS: Our study indicates that both CagA+ HP infection and CAG go along with accelerated epigenetic ageing.
