Upadacitinib Induction and Maintenance Therapy Improves Abdominal Pain, Bowel Urgency, and Fatigue in Patients With Ulcerative Colitis: A Post Hoc Analysis of Phase 3 Data.
BACKGROUND
This post hoc analysis of a large, phase 3 program evaluated the effects of upadacitinib on fatigue, bowel urgency, and abdominal pain in patients with moderately to severely active ulcerative colitis.
METHODS
Induction data were pooled from 2 identical studies, the U-ACHIEVE induction and U-ACCOMPLISH studies. Patients in these studies received upadacitinib 45 mg once daily or placebo as induction treatment. Responders to induction treatment were rerandomized in the U-ACHIEVE maintenance study to upadacitinib 15 mg once daily, upadacitinib 30 mg, or placebo. The percentage of patients reporting no abdominal pain and no bowel urgency daily via an electronic diary and a meaningful within-person change (≥5 points) in the Functional Assessment of Chronic Illness Therapy-Fatigue score were evaluated.
RESULTS
The results demonstrated a statistically significantly greater percentage of patients reporting no abdominal pain and absence of bowel urgency observed from week 2 (P < .001), with upadacitinib induction treatment and clinically meaningful improvements in Functional Assessment of Chronic Illness Therapy-Fatigue score observed at week 8 (P < .001), when compared with placebo. The maintenance study showed that significant and meaningful improvements in abdominal pain, bowel urgency, and Functional Assessment of Chronic Illness Therapy-Fatigue score achieved during induction were sustained through 52 weeks of maintenance treatment in upadacitinib- vs placebo-treated patients.
CONCLUSIONS
The findings of this study support the additional benefit of upadacitinib in treating moderately to severely active ulcerative colitis by demonstrating a statistically significant impact on clinically meaningful symptoms of fatigue, bowel urgency, and abdominal pain.(U-ACHIEVE induction and maintenance studies; NCT02819635; U-ACCOMPLISH induction study; NCT03653026).

Meta-Analysis
BACKGROUND
Gastroparesis (GP) is characterized by delayed gastric emptying in the absence of mechanical obstruction.
OBJECTIVE
Genetic predisposition may play a role; however, investigation at the genome-wide level has not been performed.
METHODS
We carried out a genome-wide association study (GWAS) meta-analysis on (i) 478 GP patients from the National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Clinical Research Consortium (GpCRC) compared to 9931 population-based controls from the University of Michigan Health and Retirement Study; and (ii) 402 GP cases compared to 48,340 non-gastroparesis controls from the Michigan Genomics Initiative. Associations for 5,811,784 high-quality SNPs were tested on a total of 880 GP patients and 58,271 controls, using logistic mixed models adjusted for age, sex, and principal components. Gene mapping was obtained based on genomic position and expression quantitative trait loci, and a gene-set network enrichment analysis was performed. Genetic associations with clinical data were tested in GpCRC patients. Protein expression of selected candidate genes was determined in full thickness gastric biopsies from GpCRC patients and controls.
RESULTS
While no SNP associations were detected at strict significance (p ≤ 5 × 10 ), nine independent genomic loci were associated at suggestive significance (p ≤ 1 × 10 ), with the strongest signal (rs9273363, odds ratio = 1.4, p = 1 × 10 ) mapped to the human leukocyte antigen region. Computational annotation of suggestive risk loci identified 14 protein-coding candidate genes. Gene-set network enrichment analysis revealed pathways potentially involved in immune and motor dysregulation (p ≤ 0.05). The GP risk allele rs6984536A (Peroxidasin-Like; PXDNL) was associated with increased abdominal pain severity scores (Beta = 0.13, p = 0.03). Gastric muscularis expression of PXDNL also positively correlated with abdominal pain in GP patients (r = 0.8, p = 0.02). Dickkopf WNT Signaling Pathway Inhibitor 1 showed decreased expression in diabetic GP patients (p = 0.005 vs. controls).
CONCLUSION
We report preliminary GWAS findings for GP, which highlight candidate genes and pathways related to immune and sensory-motor dysregulation. Larger studies are needed to validate and expand these findings in independent datasets.

Review
Functional dyspepsia is defined as persistent symptoms of postprandial bloating, early satiety, or pain in the center of the upper abdomen, without findings on upper endoscopy such as peptic ulcer disease to explain these symptoms. It is common, affecting up to 30% of the global population, but it often goes undiagnosed for years. There are 2 subtypes: epigastric pain syndrome (burning and pain) and postprandial distress syndrome (bloating and satiety). The authors discuss how to diagnose and treat both subtypes.

Review
INTRODUCTION
upon infection with SARS-CoV-2, patients presented with non-classical symptoms, such as gastrointestinal phenomena including loss of appetite, nausea, vomiting, diarrhea, and abdominal pain abdominal pain. These occurrences, typically, were found in severely affected patients with COVID-19. With this, the aim of this paper is to analyze the available knowledge on the development of acute abdomen in SARS-CoV-2 infected patients.
METHODOLOGY
this is an Integrative Review in PubMed, Web of Science and VHL databases. The following descriptors were used: "Acute abdomen", "COVID-19", "Abdominal pain" and "SARS-CoV-2" with the Boolean operator "AND", and articles relevant to the theme were selected. Initially, 331 articles were selected, all published between 2020 and 2023, in Portuguese and/or English. After analysis, 11 articles matched the proposed objective.
RESULTS
the relationship between tenderness in the right upper region or the presence of Murphy's sign contributed in the association between abdominal pain and the more severe forms of COVID-19 in infected patients. The number of diagnoses for acute conditions such as cholecystitis, appendicitis, diverticulitis and pancreatitis decreased with the pandemic, but at the same time there was an increase in the duration of surgical procedures and in the length of hospital stays. These acute abdominal conditions were the result of delayed demand for hospital care, which also contributed to an increase in the conversion rate to open surgery and in the number of perforative conditions.
CONCLUSION
the development of acute abdomen in SARS-CoV-2 infected patients was predictive of an unfavorable prognosis.

Enteric glial cells are emerging as critical players in the regulation of intestinal motility, secretion, epithelial barrier function, and gut homeostasis in health and disease. Enteric glia react to intestinal inflammation by converting to a 'reactive glial phenotype' and enteric gliosis, contributing to neuroinflammation, enteric neuropathy, bowel motor dysfunction and dysmotility, diarrhea or constipation, 'leaky gut', and visceral pain. The focus of the minireview is on the impact of inflammation on enteric glia reactivity in response to diverse insults such as intestinal surgery, ischemia, infections (C. difficile infection, HIV-Tat-induced diarrhea, endotoxemia and paralytic ileus), GI diseases (inflammatory bowel diseases, diverticular disease, necrotizing enterocolitis, colorectal cancer) and functional GI disorders (postoperative ileus, chronic intestinal pseudo-obstruction, constipation, irritable bowel syndrome). Significant progress has been made in recent years on molecular pathogenic mechanisms of glial reactivity and enteric gliosis, resulting in enteric neuropathy, disruption of motility, diarrhea, visceral hypersensitivity and abdominal pain. There is a growing number of glial molecular targets with therapeutic implications that includes receptors for interleukin-1 (IL-1R), purines (P2X2R, A2BR), PPARα, lysophosphatidic acid (LPAR1), Toll-like receptor 4 (TLR4R), estrogen-β receptor (ERβ) adrenergic α- (α-R) and endothelin B (ETBR), connexin-43 / Colony-stimulating factor 1 signaling (Cx43/CSF1) and the S100β/RAGE signaling pathway. These exciting new developments are the subject of the minireview. Some of the findings in pre-clinical models may be translatable to humans, raising the possibility of designing future clinical trials to test therapeutic application(s). Overall, research on enteric glia has resulted in significant advances in our understanding of GI pathophysiology.

59-year-old man, smoker, diabetic and hypertensive. He went to the ER due to fixed abdominal pain in the epigastrium, diaphoresis, dizziness, nausea, and "coffee grounds" vomiting. On examination he presented abdominal distension and pain on palpation in the epigastrium, without peritonism. He had a BP of 235/100 mmHg and in the blood-tests, leukocytosis with neutrophilia and normal hemoglobin. An urgent abdominal CT scan was performed, identifying a 5x6 cm nodular lesion of homogeneous density attached to the wall of the second and third duodenal portions that compressed the lumen, with two vessels with active bleeding within it. Therefore, percutaneous embolization of the gastroduodenal artery was performed. Subsequently, the patient suffered an episode of severe acute pancreatitis that required ICU admission. Finally, he presented a good clinical evolution with ceasing of pain, complete reabsorption of the hematoma and resolution of the obstructive symptoms.

BACKGROUND
Intravenous leiomyomatosis (IVL) is a rare and specific type of smooth muscle tumor that is histologically benign but has a malignant biological behavior. It is commonly associated with a history of uterine leiomyomas.
CASE PRESENTATION
A 36-year-old woman, G1P1, presented to the hospital with left lower abdominal pain for 2 months and she has accepted hysteroscopic myomectomy about 1 year ago. Ultrasound venography, echocardiography and computed tomography venography (CTV) of inferior vena cava were performed, which revealed IVL located in left intramural myometrium walls growing along the left ovarian vein reaching the level of the lumbar 5-sacral 1 disc. Laparoscopic bilateral salpingo-oophorectomy and hysterectomyis were scheduled. The IVL in the left ovarian vein and parauterine venous plexus were detected and excised completely during surgery. IVL was diagnosed by postoperative pathology and immunohistochemistry. The patient recovered well after surgery. No surgical-related or anesthesia-related complications occurred.The 3-month follow-up CTV of inferior vena cava and echocardiography examination revealed normal.
CONCLUSIONS
The cause of IVL is unknown, this observation demonstrates that hysteroscopic myomectomy might lead to the occurrence of IVL.

Review
Pain is common in inflammatory bowel disease (IBD), yet many patients feel their pain is not addressed by healthcare professionals. Listening to a patient's concerns about pain, assessing symptoms and acknowledging the impact these have on daily life remain crucial steps in addressing pain in IBD. While acute pain may be effectively controlled by pain medication, chronic pain is more complex and often pharmacological therapies, particularly opioids, are ineffective. Low-dose tricyclic antidepressants and psychological approaches, including cognitive-behavioural therapy, have shown some promise in offering effective pain management while lifestyle changes such as a trial of low-fermentable oligosaccharides, disaccharides, monosaccharides and polyols diet in those with overlapping irritable bowel syndrome may also reduce pain. Patients benefit from a long-term, trusting relationship with their healthcare professional to allow a holistic approach combining pharmacological, psychological, lifestyle and dietary approaches to chronic pain. We present a practical review to facilitate management of chronic abdominal pain in IBD.

Review
Irritable bowel syndrome (IBS) is a gastrointestinal functional disorder mainly characterised by abdominal pain, bloating and altered bowel habits. Dysbiosis might seem to be involved in the pathogenesis of the disease. Probiotics represent a potential treatment, since these could favour the functional microbiota and improve symptoms. The aim was to review the effectiveness of the use of probiotics in IBS symptomatology, analysing the influence of duration and dose. 18 articles were included. At the individual level, Lactobacillus, Bifidobacterium and Bacillus could be useful in the treatment of symptoms. Bifidobacterium bifidum reported the best results (1 × 10 CFU/day for 4 weeks). The most effective combination was 2 Lactobacillus strains, one of Bifidobacterium and one of Streptococcus (4 × 10 CFU/day for 4 weeks). Future clinical trials should confirm these results and analyse the difference between individual and combined treatments.

INTRODUCTION
To date, no international guidelines have been published for the treatment of paediatric functional abdominal pain disorders (FAPDs), subcategorised into functional abdominal pain-not otherwise specified (FAP-NOS), irritable bowel syndrome (IBS), functional dyspepsia and abdominal migraine (AM). We aim for a treatment guideline, focusing on FAP-NOS, IBS and AM, that appreciates the extensive array of available therapies in this field. We present the prospective operating procedure and technical summary protocol in this manuscript.
METHODS
Grading of Recommendations, Assessment, Development and Evaluation (GRADE) will be followed in the development of the guideline, following the approach as laid out in the GRADE handbook, supported by the WHO. The Guideline Development Group (GDG) is formed by paediatric gastroenterologists from both the European Society for Pediatric Gastroenterology, Hepatology and Nutrition, as well as the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition. Also, one clinical psychologist with expertise in FAPDs is a voting member in the GDG. A final consensus list of treatment options is translated into 'patient, intervention, comparison, outcome' format options. Prospective agreement on the magnitude of health benefits or harms categories was reached through a Delphi process among the GDG to support grading of the literature.There will be a detailed technical evidence review with randomised controlled trial data that will be judged for risk of bias with the Cochrane tool. Recommendations are preferably based on GRADE but could also be best practice statements following the available evidence. A full Delphi process will be used to make recommendations using online response systems. This set of procedures has been approved by all members of the GDG.
