Vedolizumab for the Treatment of Chronic Pouchitis.

BACKGROUND: Approximately half the patients with ulcerative colitis who undergo restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) will subsequently have pouchitis, and among those patients, one fifth will have chronic pouchitis. METHODS: We conducted a phase 4, double-blind, randomized trial to evaluate vedolizumab in adult patients in whom chronic pouchitis had developed after undergoing IPAA for ulcerative colitis. Patients were assigned (in a 1:1 ratio) to receive vedolizumab intravenously at a dose of 300 mg or placebo on day 1 and at weeks 2, 6, 14, 22, and 30. All the patients received concomitant ciprofloxacin from weeks 1 to 4. The primary end point was modified Pouchitis Disease Activity Index (mPDAI)-defined remission (an mPDAI score of ≤4 and a reduction from baseline of ≥2 points in the mPDAI total score; scores range from 0 to 12, with higher scores indicating more severe pouchitis) at week 14. The mPDAI is based on clinical symptoms and endoscopic findings. Other efficacy end points included mPDAI-defined remission at week 34, mPDAI-defined response (a reduction from baseline of ≥2 points in the mPDAI score) at weeks 14 and 34, and PDAI-defined remission (a PDAI score of ≤6 and a reduction from baseline of ≥3 points; scores range from 0 to 18, with higher scores indicating more severe pouchitis) at weeks 14 and 34. The PDAI is based on clinical symptoms, endoscopic findings, and histologic findings. RESULTS: Among the 102 patients who underwent randomization, the incidence of mPDAI-defined remission at week 14 was 31% (16 of 51 patients) with vedolizumab and 10% (5 of 51 patients) with placebo (difference, 21 percentage points; 95% confidence interval [CI], 5 to 38; P = 0.01). Differences in favor of vedolizumab over placebo were also seen with respect to mPDAI-defined remission at week 34 (difference, 17 percentage points; 95% CI, 0 to 35), mPDAI-defined response at week 14 (difference, 30 percentage points; 95% CI, 8 to 48) and at week 34 (difference, 22 percentage points; 95% CI, 2 to 40), and PDAI-defined remission at week 14 (difference, 25 percentage points; 95% CI, 8 to 41) and at week 34 (difference, 19 percentage points; 95% CI, 2 to 37). Serious adverse events occurred in 3 of 51 patients (6%) in the vedolizumab group and in 4 of 51 patients (8%) in the placebo group. CONCLUSIONS: Treatment with vedolizumab was more effective than placebo in inducing remission in patients who had chronic pouchitis after undergoing IPAA for ulcerative colitis.

Efficacy and safety of adjuvant curcumin therapy in ulcerative colitis: A systematic review and meta-analysis.

ETHNOPHARMACOLOGICAL RELEVANCE: Curcumin, an active polyphenol extracted from Traditional Chinese medicine Curcuma longa (turmeric), has shown many health-related benefits and pharmacological effects. Adjuvant curcumin therapy for ulcerative colitis has become increasingly popular, but its efficacy and safety of which is still controversial. The purpose of this study is to evaluate the efficacy and safety of adjuvant curcumin therapy in ulcerative colitis. MATERIALS AND METHODS: The Medline, EMBASE, the Cochrane Library, CNKI, VIP, WanFang, and SinoMed databases were searched from inception to June 2021, to identify all randomized controlled clinical trials with adjuvant curcumin therapy in ulcerative colitis. The primary outcomes were clinical and endoscopic remission, and subgroup analyses were also performed. RESULTS: Six randomized trials with a total of 385 participants were included in this study. Qualified trials recommended that adjuvant curcumin therapy for ulcerative colitis was effective in inducing clinical remission (RR = 2.10, 95% CI 1.13 to 3.89), but not in clinical improvement (RR = 1.62, 95% CI 1.00 to 2.61), endoscopic remission (RR = 4.17, 95% CI 0.63 to 27.71) or endoscopic improvement (RR = 4.13, 95% CI 0.20 to 87.07). Included studies showed that appropriate dosage, formation, longer duration, and topical medication may have a greater potential advantage. No severe adverse effects had been reported. CONCLUSIONS: Available evidence suggested that adjuvant curcumin therapy may be effective for clinical remission in ulcerative colitis patients without causing severe adverse effects. The appropriate methods of administration can achieve better curative effect, which requires further study to verify.

Effect of Huangqin decoction on regulating intestinal flora in colitis mice characterized as inhibition of the NOD2-dependent pathway.

CONTEXT: Chinese herb Huangqin decoction (HQD) can regulate intestinal flora in ulcerative colitis (UC) mice. OBJECTIVE: Our study clarifies the mechanism of HQD in regulating the intestinal flora of UC mice. MATERIALS AND METHODS: Male C57BL/6 mice were randomly divided into six groups: Control, Model (3% DSS), Sulfasalazine (500 mg/kg), HQD-L (250 mg/kg), HQD-M (500 mg/kg), and HQD-H (1000 mg/kg) groups. Measurement of body weight, colon length, DAI, and haematoxylin-eosin staining were conducted. FISH and 16S rDNA detected colonic bacterial infiltration and intestinal flora changes. The expression of RegIIIγ and PRRs (NOD2, TLR5, TLR4) were detected by FCM and WB, respectively. In addition, WB, qPCR, or IHC were used to detect the expression of NOD2, MyD88, RIP2, and NF-κB p65 in the colon. ELISA was used to determine cytokines. RESULTS: Compared with the model group (DAI score, 2.38 ± 0.05; histological score, 4.08 ± 0.54), HQD treatment significantly reduced the DAI score (L, 2.16 ± 0.09; M, 1.45 ± 0.05; H, 1.18 ± 0.05) and histological score (L, 3.16 ± 0.82; M, 2.50 ± 0.81; H, 1.51 ± 0.76); restored the weight, the colonic length (p < 0.05). 16S rDNA identification showed HQD regulated the balance of intestinal flora. Moreover, HQD suppressed the expression of RegIIIγ (p < 0.05) and prevented colonic bacterial infiltration. Furthermore, WB results showed NOD2, and TLR4 were inhibited by HQD, especially NOD2 (p < 0.01). The data of WB, qPCR, and IHC demonstrated that the NOD2-dependent pathway was inhibited by HQD (p < 0.01). DISCUSSION AND CONCLUSIONS: HQD (1000 mg/kg) regulates the intestinal flora of colitis mice, mainly characterized as inhibition of the NOD2-dependent pathway. These results indicate that HQD has potential.

The incidence of psoriasis among smokers and/or former smokers inflammatory bowel diseases patients treated with tumor necrosis factor antagonist: A systematic review and meta-analysis.

BACKGROUND: Infliximab (IFX) and adalimumab (ADA) refer to the classic drugs to treat moderate-severe inflammatory bowel disease (IBD), which have been proven to be effective to control IBD. However, the side effects exerted by IFX and ADA should be monitored in therapies, especially the paradoxical reaction of the skin system (e.g., psoriasis). Psoriasis is recognized as the most common skin lesion, capable of significantly affecting the quality of patients' life. METHODS: This study searched literatures published in English language with the qualifications on PubMed, Embase, Web of Science, Google, and Geenmedical databases. Over 2 co-authors assessed the quality of the articles and extracted the data independently. The data acquired were statistically analyzed with the statistical software of Revman and Stata. RESULTS: The ADA Group achieved a higher incidence of psoriasis (odds ratio [OR] = 0.658, 95% confidence interval [CI] [0.471-0.919]); Females achieved a higher incidence of psoriasis than males (OR = 1.941, 95%CI [1.326-2.843], P < .05); Smoking up-regulated the incidence of psoriasis (OR = 1.679, 95%CI [1.237-2.279], P < .05); The interval of medication was over 1 year, and the interval of medication applying IFX was longer than that of the ADA Group; most cases could be relieved by using local hormone, phototherapy, or systemic hormone therapy under the strategy of biological agents. CONCLUSIONS: The frequency of reported in IBD exceeds those of other autoimmune diseases, and the ADA treatment for IBD is safer than IFX. Psoriasis is more common in females than in males. Smoking refers to one of risk factors of psoriasis.

Limonene from Agastache mexicana essential oil produces antinociceptive effects, gastrointestinal protection and improves experimental ulcerative colitis.

ETHNOPHARMACOLOGY RELEVANCE: Agastache mexicana is a popular plant of great demand in folk medicine, essentially due to its calming properties and for alleviating arthritic, muscular and abdominal pain. Despite its spectrum for pain relief, pharmacological studies of its bioactive constituents have been barely investigated. AIM OF THE STUDY: To evaluate protective properties of the A. mexicana and bioactive compounds improving pathological gastrointestinal conditions in rodents. MATERIAL AND METHODS: Different doses of the essential oil of A. mexicana ssp. mexicana and ssp. xolocotziana (30-562.2 mg/kg, i.p.) and individual monoterpenes (3-300 mg/kg, i.p.) were evaluated in an abdominal pain model. The most active monoterpene limonene and sulfasalazine (reference drug, 100 mg/kg, p.o.) were also evaluated in the oxazolone-induced colitis model using an oral gavage, where some inflammatory cytokines were analyzed by enzyme-linked immunosorbent assays. Finally, colonic histological assessment and gastroprotection in the absolute ethanol-induced ulcer model were explored. RESULTS: Our results demonstrated that the essential oil of both subspecies produced a significant reduction in the abdominal writhes, where monoterpenes limonene and pulegone were partially responsible bioactive metabolites. Limonene showed the major antinociceptive efficacy in the writhing test. It also significantly decreased hyperalgesia, pathological biomarkers, and colonic inflammatory cytokines in the oxazolone-induced colitis model, as well as prevention in gastric damage. CONCLUSIONS: Present results provide scientific evidence to reinforce the use of A. mexicana in the traditional medicine for gastrointestinal conditions, mainly related to pain and inflammation, demonstrating the potential of monoterpenes as natural products in the therapeutics of gastrointestinal affections such as ulcer, colitis, and abdominal pain.

Ustekinumab is more effective than azathioprine to prevent endoscopic postoperative recurrence in Crohn's disease.

BACKGROUND: Preventing postoperative recurrence (POR) is a major concern in Crohn's disease (CD). While azathioprine is an option, no data is available on ustekinumab efficacy in this situation. AIMS: We compared the effectiveness of ustekinumab versus azathioprine in preventing endoscopic POR in CD. METHODS: We retrospectively collected data from all consecutive CD patients treated with ustekinumab after intestinal resection in 9 centers. The control group (azathioprine alone) was composed of patients who participated in a randomized controlled trial conducted in the same centers comparing azathioprine alone or in combination with curcumin. Propensity score analyses (inversed probability of treatment weighting = IPTW) were applied to compare the two groups. The primary endpoint was endoscopic POR (Rutgeerts' index ≥ i2) at 6 months. RESULTS: Overall, 32 patients were included in the ustekinumab group and 31 in the azathioprine group. The propensity score analysis was adjusted on the main risk factors (smoking, fistulizing phenotype, prior bowel resection, resection length >30 cm and ≥2 biologics before surgery) and thiopurines or ustekinumab exposure prior to surgery making the two arms comparable (∣d∣ < 0.2). After IPTW, the rate of endoscopic POR at 6 months was lower in patients treated with ustekinumab compared to azathioprine (28.0% vs. 54.5%, p = 0.029). After IPTW, the rates of i2b-endoscopic POR (Rutgeerts' index ≥ i2b) and severe endoscopic POR (Rutgeerts' index ≥ i3) were 20.8% versus 42.5% (p = 0.066) and 16.9% versus 27.9% (p = 0.24), in the ustekinumab and azathioprine groups, respectively. CONCLUSION: Ustekinumab seemed to be more effective than azathioprine in preventing POR in this cohort of CD patients.

Gastric Enzyme Supplementation Inhibits Food Allergy in a BALB/c Mouse Model.

Impaired gastric digestion due to suppressed gastric acidity enhances the risk for food allergy development. In the current study, we aimed to evaluate the impact of a supported gastric digestion via application of a pharmaceutical gastric enzyme solution (GES) on food allergy development and allergic reactions in a BALB/c mouse model. The ability of the GES to restore hypoacidic conditions was tested in mice treated with gastric acid suppression medication. To evaluate the impact on allergic symptoms, mice were orally sensitized with ovalbumin (OVA) under gastric acid suppression and subjected to oral challenges with or without GES. The immune response was evaluated by measurement of antibody titers, cytokine levels, mucosal allergy effector cell influx and regulatory T-cell counts. Clinical response was objectified by core body temperature measurements after oral OVA challenge. Supplementation of GES transiently restored physiological pH levels in the stomach after pharmaceutical gastric acid suppression. During oral sensitization, supplementation of gastric enzymes significantly reduced systemic IgE, IgG1 and IgG2a levels and allergic symptoms. In food allergic mice, clinical symptoms were reduced by co-administration of the gastric enzyme solution. Support of gastric digestion efficiently prevents food allergy induction and alleviates clinical symptoms in our food allergy model.

Improved work productivity and health-related quality of life in patients with irritable bowel syndrome with diarrhea receiving eluxadoline following inadequate response to loperamide.

BACKGROUND: Irritable bowel syndrome with diarrhea (IBS-D) is a chronic disorder of gut-brain interaction that negatively affects work productivity and health-related quality of life (HRQOL). IBS-D therapeutic options are limited and include loperamide, an over-the-counter µ-opioid receptor agonist commonly used as an antidiarrheal agent, and eluxadoline, a mixed µ- and κ-opioid receptor agonist and δ-opioid receptor antagonist approved in the United States for the treatment of IBS-D in adults. OBJECTIVE: To characterize the effect of eluxadoline on work productivity and HRQOL in patients with IBS-D with previous inadequate response to loperamide. METHODS: The Work Productivity and Activity Impairment Questionnaire for IBS-D (WPAI:IBS-D), Centers for Disease Control and Prevention Healthy Days Core Module (CDC HRQOL-4), and EuroQoL-5 Dimension (EQ-5D) instruments were administered at baseline and week 12 of a phase 4 clinical trial (RELIEF), assessing the efficacy and safety of eluxadoline treatment in adults with IBS-D reporting previous inadequate response to loperamide. Changes from baseline to week 12 for each assessment were evaluated using an analysis of covariance model. Indirect costs were calculated by converting overall work productivity losses into monetary values. RESULTS: A total of 346 patients were randomized to either eluxadoline (n = 172) or placebo (n = 174). From baseline to week 12, compared with placebo, twice-daily treatment with eluxadoline resulted in significantly greater reductions in absenteeism (2.6%; P = 0.046). Numerically greater decreases in presenteeism, overall work productivity loss, and daily activity impairment were also observed in patients receiving eluxadoline compared with those receiving placebo (P = not significant for each). Numerical reductions in overall work productivity loss from baseline to week 12 translate to approximately 2.4 hours per patient per week (123 hours annually) and correspond to an avoided overall work loss of $4,503 annually for an employee with IBS-D treated with eluxadoline. In addition, from baseline to week 12, treatment with eluxadoline led to a significantly greater reduction in the number of unhealthy days experienced (-1.7 days; P = 0.042), as well as numerical improvements in EQ-5D measures in comparison with placebo (P = not significant for each). CONCLUSIONS: In patients with IBS-D reporting inadequate response to loperamide, eluxadoline treatment was associated with significant reductions in absenteeism and the number of unhealthy days experienced. Eluxadoline treatment of IBS-D may lead to significant cost savings via mitigation of losses in work productivity.

Lipi Guben decoction in treating diarrheal irritable bowel syndrome: A study protocol for a randomized controlled trial.

BACKGROUND: Irritable bowel syndrome (IBS) is a common functional bowel disorder. The global incidence of IBS is as high as 9% to 23%, accounting for about 50% of outpatients in gastroenterology, and the new case detection rate is 0.2% every year. IBS has become a global gastrointestinal functional disease. Although IBS is not a life-threatening disease, it seriously affects the quality of life of patients, causing huge economic and mental burden to individuals, society and families. Lipi Guben decoction (LPGBD) is an important auxiliary treatment for IBS, but lack of robust Evidence-based medicine evidence proving its efficacy. Therefore, we designed a randomized controlled trial to evaluate the efficacy and safety of LPGBD in the treatment of IBS. METHODS: In this randomized controlled trial, a total of 100 eligible patients will be allocated to the blank control group or LPGBD group in a ratio of 1:1. The treatment period was 12 weeks. The primary outcome measure will be the total clinical effective rate. The Secondary outcomes will include IBS clinical symptom scores, IBS-Severity Scoring System, IBS-Quality of life, Hamilton Rating Scale for Anxiety, Hamilton Rating Scale for Depression, and Bristol Stool Form Scale. The safety outcome will include Echocardiogram, blood examination (including blood routine test, liver function test, and renal function test), urine routine test and stool routine test. The evaluation indicators and all safety results will be performed at baseline, week 4, week 8 and week 12. RESULTS: This study will be helpful to evaluate the efficacy and safety of LPGBD in the treatment of IBS. CONCLUSION: LPGBD may improve the clinical efficacy of patients with IBS, which has important value in practical application.

Comparative effectiveness of lactulose and sennosides for the prevention of peritoneal dialysis-related peritonitis: an open-label, randomized, active-controlled trial.

BACKGROUND: To the best of our knowledge, the effectiveness and safety of lactulose in comparison to sennosides, for the prevention of peritoneal dialysis (PD)-related peritonitis, has never been tested in a randomized study. METHODS: We conducted an open-label, randomized, active-controlled trial in a PD-center in Northern Thailand. Adult patients on PD were enrolled and randomly assigned in a 1:1 ratio into two groups; one group received lactulose 15 mL once daily (n = 50) and the other group received sennosides two tablets daily (n = 50). The primary outcome was time-to-first bacterial peritonitis. The secondary outcomes included a composite of bacterial peritonitis and all-cause mortality. Cox proportional hazards regression was calculated and presented as hazard ratios (HRs) with 95% confidence intervals (CIs). RESULTS: One hundred PD patients were recruited (50.0% men; mean age 55.5 ± 13.0 years) in this study. The baseline characteristics of the study participants were similar in both groups. No significant trend towards a higher risk of PD-related peritonitis was observed in the lactulose group (HR, 2.32 [95% CI, 0.92-5.83]; p = .051) compared to the sennosides group. Nevertheless, the secondary outcome was significantly higher in the lactulose group (HR, 2.77 [95% CI, 1.20-6.41]; p = .010). The incidence of adverse events was not substantially different between the two groups; however, diarrhoea was more frequent in the lactulose group (38.0% vs. 18.0%; p = .030) than in the sennosides group. CONCLUSIONS: Treatment with lactulose is not more effective than sennosides and cannot be routinely recommended for the prevention of peritonitis among the PD population. TRIAL REGISTRATION Thai Clinical Trial Registry (clinicaltrials.in.th); ID: TCTR20171012001 KEY MESSAGE To the best of our knowledge, no randomized controlled trial that compares the efficacy and safety profiles of lactulose versus sennosides for the prevention of PD-related peritonitis among the PD population has been conducted. In this open-label, randomized, active-controlled trial, treatment with lactulose is not more effective than sennosides in the prevention of PD-related peritonitis, and it could increase the risk of bacterial PD-related peritonitis. Further studies with a larger sample size by incorporated real-world evidence are needed to confirm our findings and to explore strategies to prevent peritonitis among PD patients.

Adherence to intravenous biological treatment in inflammatory bowel disease patients during the COVID-19 pandemic.

The objective of this study was to determine the adherence to biological treatment in inflammatory bowel disease (IBD) patients during the COVID-19 pandemic at Hospital Universitario La Paz, in Madrid. All patients from our IBD Unit were informed via e-mail, social networks and websites about the convenience of continuing with treatment. In addition, patients were contacted by telephone a few days before to remind them of their appointment and the importance of adherence.

FACTORS ASSOCIATED WITH PATIENT´S PREFERENCE IN CHOOSING THEIR THERAPY FOR INFLAMMATORY BOWEL DISEASE IN BRAZIL.

OBJECTIVE: This study aims to evaluate patient's preferences in the choice of their therapy and the factors that influence this choice. METHODS: This cross-sectional study enrolled 101 outpatients with Crohn's disease or ulcerative colitis. The inclusion criteria were age ≥18 years and no previous exposure to biological therapy. Patients' preferences were assessed through questions that addressed the preferred mode of administration (oral, subcutaneous, or intravenous) and the factors that determined the choice of medication (efficacy, medical indication, fear of medication, convenience, mode of application, and personal doctors' indication). RESULTS: The mean age was 43.6±13.5 years, 75.3% were female, and 81.2% were cases of ulcerative colitis. Regarding the mode of administration, the majority of patients preferred oral (87.1%), followed by intravenous (6.93%) and subcutaneous (5.94%) medications. The reasons were "I prefer to take it at home" (42.57%), "I have more freedom" (36.63%), "I don't like self-application" (29.70%), and "I believe it works better" (19.80%). Younger patients and patients in clinical disease activity preferred intravenous mode compared to the oral route (P<0.05). Doctor's opinion (98%) was an important factor associated with the medication choice. CONCLUSION: Oral route was the preferred mode of administration and most patients took their physician's opinion into account in their choice of medication.

Identification and Comparison of Peptides from Chickpea Protein Hydrolysates Using Either Bromelain or Gastrointestinal Enzymes and Their Relationship with Markers of Type 2 Diabetes and Bitterness.

The chickpea (Cicer arietinum L.) is one of the most important pulses worldwide. The objective was to identify, compare and evaluate peptides from chickpea hydrolysates produced by two enzymatic treatments. The antidiabetic potential and bitterness of the peptides and induction of bitter receptors were identified in silico. Proteins were isolated from the Kabuli variety. Peptides were produced from the proteins using a simulated digestive system (pepsin/pancreatin, 1:50 Enzyme/Protein, E/P), and these peptides were compared with those produced via bromelain hydrolysis (1:50 E/P). The protein profiles, sequences and characteristics of the peptides were evaluated. The biochemical inhibition and molecular docking of dipeptidyl peptidase-IV (DPP-IV), α-amylase and α-glucosidase were also studied. The molecular docking identified peptides from enzymatic hydrolysis as inhibitors of DPP-IV. The high hydrophobicity of the peptides indicated the potential for bitterness. There was no correlation between peptide length and DPP-IV binding. Peptides sequenced from the pepsin/pancreatin hydrolysates, PHPATSGGGL and YVDGSGTPLT, had greater affinity for the DPP-IV catalytic site than the peptides from the bromelain hydrolysates. These results are in agreement with their biochemical inhibition, when considering the inhibition of sitagliptin (54.3 µg/mL) as a standard. The bitter receptors hTAS2R38, hTAS2R5, hTAS2R7 and hTAS2R14 were stimulated by most sequences, which could be beneficial in the treatment of type 2 diabetes. Chickpea hydrolysates could be utilized as functional ingredients to be included in the diet for the prevention of diabetes.

Fatores associados com a escolha da terapia nos pacientes com doença inflamatória intestinal no Brasil / Factors associated with patient´s preference in choosing their therapy for inflammatory bowel disease in brazil

BACKGROUND: Biological therapy and new drugs have revolutionized the treatment of inflammatory bowel disease. Ideally, the choice of medication should be a shared decision with the patient, aiming at greater satisfaction, compliance, and consequently, favorable clinical outcome. OBJECTIVE: This study aims to evaluate patient's preferences in the choice of their therapy and the factors that influence this choice. METHODS: This cross-sectional study enrolled 101 outpatients with Crohn's disease or ulcerative colitis. The inclusion criteria were age ≥18 years and no previous exposure to biological therapy. Patients' preferences were assessed through questions that addressed the preferred mode of administration (oral, subcutaneous, or intravenous) and the factors that determined the choice of medication (efficacy, medical indication, fear of medication, convenience, mode of application, and personal doctors' indication). RESULTS: The mean age was 43.6±13.5 years, 75.3% were female, and 81.2% were cases of ulcerative colitis. Regarding the mode of administration, the majority of patients preferred oral (87.1%), followed by intravenous (6.93%) and subcutaneous (5.94%) medications. The reasons were "I prefer to take it at home" (42.57%), "I have more freedom" (36.63%), "I don't like self-application" (29.70%), and "I believe it works better" (19.80%). Younger patients and patients in clinical disease activity preferred intravenous mode compared to the oral route (P<0.05). Doctor's opinion (98%) was an important factor associated with the medication choice. CONCLUSION: Oral route was the preferred mode of administration and most patients took their physician's opinion into account in their choice of medication.

RESUMO CONTEXTO: A terapia biológica e os novos medicamentos revolucionaram o tratamento da doença inflamatória intestinal. A escolha do medicamento deve ser compartilhada com o paciente, visando maior satisfação, adesão e, consequentemente, desfecho clínico favorável. OBJETIVO: Este estudo teve como objetivo avaliar as preferências do paciente na escolha de sua terapia e os fatores que influenciaram essa escolha. MÉTODOS: Este estudo transversal incluiu 101 pacientes ambulatoriais com doença de Crohn ou retocolite ulcerativa. Os critérios de inclusão foram idade ≥18 anos e nenhuma exposição prévia à terapia biológica. A preferência dos pacientes foi avaliada por meio de perguntas que abordaram o modo de administração preferido (oral, subcutâneo ou intravenoso) e os fatores que determinaram a escolha do medicamento (eficácia, indicação médica, medo da injeção, conveniência, modo de aplicação e opinião pessoal do médico). RESULTADOS: A idade média foi de 43,6±13,5 anos, 75,3% eram mulheres e 81,2% eram portadores de retocolite ulcerativa. Em relação ao modo de administração, a maioria dos pacientes preferiu os medicamentos orais (87,1%), seguidos dos endovenosos (6,93%) e subcutâneos (5,94%). Os motivos foram "prefiro aplicar em casa" (42,57%), "tenho mais liberdade com essa medicação" (36,63%), "não gosto de autoaplicação" (29,70%) e "acredito que funcione melhor" (19,80%). Pacientes jovens e pacientes em atividade clínica preferiram a via intravenosa em comparação com a via oral (P<0,05). A opinião do médico (98%) foi um fator importante associado à escolha do medicamento. CONCLUSÃO: A via oral foi preferida e a maioria dos pacientes levou em consideração a opinião do seu médico na escolha do medicamento.

Assessment of Body Weight Changes in Patients with Inflammatory Bowel Diseases Initiating Biologic Therapy: A Prospective Cohort Study.

BACKGROUND: Prior studies have inconsistently suggested that biologic therapy may be associated with weight gain in inflammatory bowel disease patients (IBD). Our aim was to compare weight gain across different biologic therapy classes with distinct mechanisms of action. METHODS: This prospective cohort study recruited patients with moderate to severe IBD initiating outpatient biologic therapy with anti-TNF (infliximab, adalimumab), vedolizumab, or ustekinumab. Weight measurements were performed at weeks 0, 14, 30, and 54. Changes in weight between baseline and each of the follow-up visits were modeled as a continuous variable, and multivariate regression assessed the independent effect of therapeutic class on this outcome. RESULTS: Our study enrolled 269 patients (163 CD, 106 UC) initiating biologic therapy [99 anti-TNF (37%), 122 vedolizumab (45%), 48 ustekinumab (18%)]. From baseline, the weight significantly increased at week 14 with a mean of 0.36 kg (± 3.8 kg, p = 0.004) and continued to increase compared to baseline with 0.96 kg (± 3.9 kg, p < 0.001) and 1.29 kg (± 4.2 kg, p < 0.001) at week 30 and 54, respectively. On univariate and multivariable analysis, no significant differences between any of the biologic therapies for weight gain were seen at any time point (weight gain anti-TNF: 0.31 kg, 1.06 kg, 1.33 kg; VDZ: 0.30 kg, 0.83 kg, 1.10 kg; UST: 0.63 kg, 1.21 kg, 2.31 kg at wk 14, wk 30, and wk 54, respectively). None of the disease activity parameters showed any statistical association with weight gain. CONCLUSION: There was no difference in weight gain among the different biologic therapeutic classes.

Tumor Necrosis Factor Inhibitor-Induced Psoriasis in a Pediatric Crohn's Disease Patient Successfully Treated with Ustekinumab.

BACKGROUND: Tumor necrosis factor (TNF) inhibitors are widely used in pediatric patients with inflammatory bowel disease, as well as psoriasis. However, there is growing evidence that these medications can also paradoxically induce a psoriasiform skin reaction in a subset of patients. GOALS: We seek to share our experience in treating severe TNF inhibitor-induced psoriasis in a pediatric patient with Crohn’s disease. STUDY: We report a case of a 10-year-old female with Crohn’s disease, who developed psoriasis after twelve months of infliximab therapy. Her skin disease was recalcitrant to topical therapies, methotrexate, and phototherapy. RESULTS: The patient was transitioned to ustekinumab with significant improvement in her symptoms and maintenance of remission of her bowel disease. CONCLUSION: This is the first reported case of a school-age pediatric patient with TNF inhibitor-induced psoriasis treated with ustekinumab. Controlled trials are warranted to fully assess the safety and efficacy of ustekinumab for treating TNF inhibitor-induced psoriasis in the pediatric population.J Drugs Dermatol. 2020;19(3): doi:10.36849/JDD.2020.2106.

Colonic transendoscopic tube-delivered enteral therapy (with video): a prospective study.

BACKGROUND: Colonic transendoscopic enteral tubing (TET) refers to colonic transendoscopic tube-delivered enteral therapy. Colonic TET has been successfully used for frequent colonic administration of drugs or multiple fecal microbiota transplantations (FMTs). This prospective observational study aimed to evaluate possible factors affecting methodology, feasibility and safety of colonic TET. METHODS: Patients who underwent colonic TET at our center from October 2014 to November 2018 were included. The feasibility, efficacy, and safety of TET were evaluated. RESULTS: In total, 224 patients were analyzed. The success rate of TET was 100%. The median retention time of TET tube within the colonic lumen was 8.5 (IQR 7-11) days in 158 patients with tube falling out spontaneously, and the maximum retention time was up to 28 days. These patients were divided into the short-retention group (≤ 8.5 days) and the long-retention group (> 8.5 days). Univariate and multivariate analysis demonstrated that the type of endoscopic clip (p = 0.001) was an independent factor for the retention time. The larger clips as well as a greater number of clips significantly affected the retention time (p = 0.013). No severe adverse event was observed during and after TET. CONCLUSIONS: Colonic TET is a feasible, practical, and safe colon-targeted drug delivery technique with a high degree of patients' satisfaction. Two to four large endoscopic clips are recommended to maintain stability of the TET tube within the colon for over 7 days.

Efficacy of Electro-acupuncture in Treatment of Functional Constipation: A Randomized Controlled Trial.

Functional constipation (FC) is a chronic disease that significantly affects the life quality of patients. Acupuncture has been used for the treatment of FC for many years, but its effectiveness has not been scientifically assessed. The present study aimed to evaluate the efficacy of electro-acupuncture (EA) in relieving the symptoms, mental states and quality of life (QOL) of FC patients. A total of 96 FC patients were randomly allocated into EA, mosapride & sham EA group (MS) and mosapride control group (MC). In the EA group, patients were treated with 16 sessions of needling at Quchi (LI11) and Shangjuxu (ST37) bilaterally, 5 times a week in the first 2 weeks, and 3 times a week in the last 2 weeks. In the MC group, patients were treated with 5 mg mosapride citrate three times a day for 4 weeks. In the MS group, patients underwent sham EA and the same mosapride citrate treatment as in the MC group. The primary outcome was the number of weekly spontaneous bowel movements (SBMs). The secondary outcomes included stool consistency, intensity of defecating difficulty, 36-Item Short-Form Health Survey (SF-36), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and the validated Patient Assessment of Constipation-Quality of Life (PAC-QOL). The results showed that as compared with the baseline, EA significantly improved the weekly SBMs, stool consistency and intensity of defecating difficulty (P<0.05). It also partly ameliorated the PAC-QOL, SF-36, SDS and SAS scores when compared with MC or MS group (P<0.05). However, no significant difference was observed between MS and MC groups in bowel function outcomes and QOL scores. It was concluded that EA could effectively improve bowel function, mental states and QOL of FC patients.

14-Day High-Dose Amoxicillin- and Metronidazole-Containing Triple Therapy With or Without Bismuth as First-Line Helicobacter pylori Treatment.

BACKGROUND: Amoxicillin, metronidazole, proton pump inhibitor, bismuth quadruple therapy had been shown to reliably achieve high eradication rates. The role of individual components remains undefined. AIM: To identify the additional benefit/role of bismuth in amoxicillin, metronidazole, proton pump inhibitor, bismuth quadruple therapy for Helicobacter pylori (H. pylori) treatment. METHODS: This was a non-inferiority factorial design trial. Treatment-naive H. pylori-infected subjects were randomly (1:1) assigned to receive 14-day amoxicillin- and metronidazole-containing triple therapy consisting of esomeprazole 20 mg twice a day, amoxicillin 1 g, and metronidazole 400 mg both thrice daily with or without 220 mg bismuth twice a day. Six weeks after treatment, H. pylori eradication was assessed by 13C-urea breath test. Antimicrobial susceptibility was assessed by the twofold agar dilution method. RESULTS: From July 2018 to June 2019, a total of two hundred and sixteen subjects were randomized. Both therapies achieved high eradication rates. Per-protocol with bismuth = 97.9% (94/96, 95% CI 95.1-100%) and without bismuth = 94.7% (90/95, 95% CI 90.3-99.1%) (P = 0.43). Intent-to-treat analysis = 90.7% (98/108, 95% CI 85.2-96.2%) versus 88.9% (96/108, 95% CI 82.8-95.0%) with and without bismuth (P = 0.65). The two regimens were not inferior by intent-to-treat or per-protocol analyses. Metronidazole resistance did not affect the efficacy of either therapy. CONCLUSION: Neither the presence nor absence of bismuth or metronidazole resistance reduced the effectiveness of triple therapy containing esomeprazole 20 mg twice a day, amoxicillin 1 g, and metronidazole 400 mg thrice daily in this population. The clinical trial was registered with ClinicalTrials.gov, NCT03557437.
