ABSTRACTIntroductionWhile gastrointestinal involvement is a common manifestation of systemic lupus erythematosus (SLE), the association between gastroparesis and SLE remains unclear.MethodsWe analyzed data from the National Inpatient Sample (NIS) database from 2016 to 2021. Patients with gastroparesis were categorized into SLE and non‐SLE groups. Similarly, patients with SLE were categorized into gastroparesis and nongastroparesis groups. Clinical characteristics, comorbidities, hospitalization data, and outcomes were compared. The primary outcome was the association between SLE and primary gastroparesis. Secondary outcomes were clinical impacts of gastroparesis in patients with or without SLE.ResultsA total of 12 538 228 patients were included from the NIS database. Of these, 1 165 925 patients (9.3%) were diagnosed with gastroparesis during hospitalization, while 11 372 303 patients (90.7%) did not have gastroparesis. SLE was significantly more common in patients with gastroparesis compared to those without (1.6% vs. 0.7%, p < 0.001; aOR 1.87 [95% CI: 1.80–1.95]). Among patients hospitalized with gastroparesis, those with SLE had a longer length of stay, with a β‐coefficient of 0.31 (95% CI: 0.07–0.55, p = 0.009), lower hospitalization charges, with mean differences of $4761 (95% CI: 442–9080, p = 0.031), and a higher rate of intervention needs, with odds ratios of 1.31 (95% CI: 1.09–1.56, p = 0.003). After propensity‐score matching (1:1), SLE patients aged ≥ 65 had higher hospital charges, with mean differences of $7287 (95% CI: 2928–11 646, p = 0.01), compared to non‐SLE patients.ConclusionGastroparesis is associated with SLE, contributing to longer hospitalizations, higher costs, and increased need for invasive interventions. These findings underscore the importance of evaluating gastroparesis in SLE patients to enable early management and reduce potential complications.

Dietary characteristics associated with non-alcoholic fatty liver disease (NAFLD) and metabolic dysfunction-associated steatotic liver disease (MASLD) in non-obese patients remain to be elucidated. This study examined the association of NAFLD and MASLD with dietary characteristics according to obesity status. We performed a cross-sectional study of 15 135 participants (n = 7568 men and 7567 women) aged 35-74 years using data of annual health checks between 2008 and 2020. Obesity was defined as BMI ≥ 25 kg/m2. Diagnosis of fatty liver was based on abdominal ultrasonography. Fatty-liver-related dietary characteristics were assessed using a self-administered questionnaire. For non-obese participants, NAFLD was found in 31.0% of men and 19.4% of women. Non-obese MASLD was found in 27.6% of men and 18.1% of women. Multivariable-adjusted stepwise logistic regression analysis indicated that, in males, both non-obese NAFLD and non-obese MASLD were significantly and negatively associated with "often eat sesame/nuts", and positively associated with "often eat noodles/rice bowl" and "often eat evening meal" (P < 0.05). For non-obese women, both NAFLD and MASLD were significantly and positively associated with "often eat sweet buns/bread with fillings" (P < 0.05). Adjusted analyses showed that all dietary characteristics were not significantly associated with the risk of NAFLD/MASLD in obese men and women. This cross-sectional study indicates the existence of sex and obesity differences in the association of NAFLD and MASLD with dietary characteristics. Our findings suggest that some dietary characteristics are associated with NAFLD and MASLD prevalence in non-obese Japanese participants.

Combining proton pump inhibitors (PPIs) with prokinetics can provide synergistic action in patients with gastroesophageal reflux disease (GERD) and overlapping dyspepsia, but data regarding this is lacking. This single-center, prospective study evaluated the efficacy and safety of 6-week treatment with fixed-drug combination (FDC) of pantoprazole (PPI) and itopride (prokinetic) in 50 patients with ≥3 month history of GERD and overlapping dyspepsia refractory to pantoprazole. Efficacy was assessed as reduction in GERD symptom assessment scale (GSAS) distress score for 15 symptoms from baseline to week 6. Adverse events (AEs) were monitored up to week 6. Although heartburn was the most common symptom at week 6 (26.8%), its frequency significantly decreased from baseline (84.0%; P <0.01). A similar trend was observed for other symptoms: pressure/discomfort inside chest (19.5%), belching (14.6%), regurgitation (12.2%), bloating (9.8%), flatulence (9.8%), early satiety (7.3%), acidic/sour taste in mouth (7.3%), nausea (7.3%), frequent gurgling in stomach/belly (4.9%), and pressure/lump in throat (2.4%). Mean distress scores of all symptoms markedly decreased at week 6. Three AEs (n = 2) of moderate intensity were reported. The FDC of pantoprazole and itopride showed favorable efficacy and safety in patients with GERD and overlapping dyspepsia refractory to pantoprazole monotherapy. Nevertheless, further studies are warranted.

Semaglutide has been studied in patients with metabolic dysfunction-associated steatohepatitis (MASH) due to potential benefit from weight loss on liver inflammation. However, preclinical studies suggest that MASH improvement may be independent of weight loss. We aim to assess the impact of semaglutide on MASH in relation to weight loss. This retrospective study included 420 patients with diabetes on semaglutide for at least 12 months between 2011 and 2022. Exclusion criteria were liver disease other than MASH, decompensated cirrhosis, malignancy, and bariatric surgery. Primary endpoints were clinically significant improvements in AST or ALT (mean difference > 6.3 U/L and > 10.6 U/L respectively). Statistical analysis included Student's t-test/ANOVA, Wilcoxon signed-rank test/Friedman test as appropriate, and binary logistic regression. Median duration of semaglutide was 22.5 months and 80% of patients received 1 mg/week. BMI improved by a mean (SD) of 1.9 points (2.8), weight by 13.3 lbs. (19.1), AST by 4.1 U/L (11.5), and ALT by 5.3 U/L (14.2). In 28% and 22% of patients respectively, AST and ALT had a clinically significant improvement. MASH scores (NFS, FIB4, APRI) improved after semaglutide (p < 0.001). No statistically significant differences in AST or ALT improvement were found when patients were stratified by BMI prior to semaglutide or when stratified by percentage of weight loss. On logistic regression, the duration of semaglutide and pretreatment APRI score increased the odds of clinically significant improvements of AST and ALT. Semaglutide treatment was associated with improvement in transaminases and MASH scores. Higher odds of positive semaglutide effects were observed with longer treatment duration and were independent of weight loss.

Pouchitis is a common complication after restorative ileal pouch-anal anastomosis following proctocolectomy for ulcerative colitis. Antibiotic-dependent or antibiotic-refractory chronic pouchitis (CP), which is a common cause of pouch failure affecting 15-20% of patients, is challenging to treat. The efficacy of second-line immunomodulator and biologic therapy remains poorly defined. We present a pooled analysis of real-world efficacy data from peer-reviewed full-text manuscripts, focusing on immunomodulator and biologic therapies in CP. Embase and PubMed databases were searched for full-text articles describing the treatment of CP. We performed a systematic review and pooled analysis of published studies to assess the efficacy of immunomodulators, including thiopurines and methotrexate, and biologics including antitumor necrosis factor, anti-integrin, and interleukin-12/23 antagonists. Clinical and endoscopic response and remission rates were combined for pooled analyses. Rates of treatment discontinuation and safety were also assessed. Pooled analysis comprised 20 full-text articles (485 patients). Overall clinical response rate was 46% (95% CI: 35-59%) and clinical remission rate was 35% (95% CI: 21-52%). Overall endoscopic response and remission rates were 41% (95% CI: 18-68%) and 15% (95% CI: 5-39%), respectively. Individual agents' safety profile was reassuring, with vedolizumab being the most favorable. The real-world efficacy data of immunomodulators in the treatment of CP is insufficient. Vedolizumab and ustekinumab appeared effective and safe for CP, whereas anti-TNFs showed higher rates of adverse events. The high heterogeneity within the studies is attributed to the real-world study design, obfuscating drug efficacy comparisons across the studies. Further studies are required to define the comparative effectiveness of available treatments of CP.

Many recent studies have shown a relationship between various systemic diseases and the gut microbiota (GM), with the gut-liver axis receiving particular attention. In contrast, no report has comprehensively shown the effects of GM on the pathophysiology of patients undergoing living donor liver transplantation (LDLT). We enrolled 16 recipients who underwent LDLT for liver cirrhosis, and 17 donors constituted the reference group. We examined the differences in GM between recipients and donors. We also examined the relationships between GM, short-chain fatty acids, and portal vein pressure (PVP) in recipients. There was no significant difference in alpha-diversity between the recipients and donors, but there was variation in beta-diversity among the recipients. The abundance of the phylum Bacteroidetes was significantly higher in recipients than in donors (P = 0.016), and it was positively correlated with PVP (r = 0.511, P = 0.043). Propionic acid, which is a component of short-chain fatty acids, was positively correlated with PVP (r = 0.544, P = 0.0295), the phylum Bacteroidetes (r = 0.677, P = 0.004), and total bilirubin concentration (r = 0.501, P = 0.048). Propionic acid was negatively correlated with serum albumin concentration (r = -0.482, P = 0.043). Our findings suggest relationships between fecal Bacteroidetes levels, propionic acid concentrations, and PVP in patients with liver cirrhosis undergoing LDLT.
