RESUMEN
Background: Patients with inflammatory bowel disease (IBD) may also experience extraintestinal manifestations (EIMs), which can affect various organ systems, and their occurrence is based on disease activity. Objectives: To determine the prevalence of EIMs and their most common types among IBD patients from Saudi Arabia. Materials and Methods: This retrospective study included all IBD patients aged 14-80 years who visited the Gastroenterology and Hepatology clinics at King Fahad Medical City, Riyadh, between February 2017 and December 2022. The collected data included demographic characteristics, disease characteristics, EIMs, and treatment. Results: The study included 578 IBD patients, of which 65 (11.2%) had at least one EIM, with primary sclerosing cholangitis (46.2%) and sacroiliitis (16.9%) being the most common. Patients with ulcerative colitis were more likely to have EIMs than those with Crohn's disease (15.1% vs. 9%; P = 0.026). Patients with ileocolonic (L3) Crohn's disease reported a higher prevalence of EIMs (7.5%) than those with other disease locations (P = 0.012), while in patients with ulcerative colitis, those with extensive colitis (E3) reported higher prevalence of EIMs (19.2%) (P = 0.001). Patients receiving 6 MP had a significantly high prevalence of EIMs (P = 0.014). Conclusion: The prevalence of extraintestinal manifestations among IBD patients in Saudi Arabia is 11.2%. These findings suggest the need for clinicians to screen for EIMs and manage them early. Further research is needed to understand the mechanisms underlying EIMs for the development of more effective treatments.
RESUMEN
Background: Patients with inflammatory bowel disease (IBD) are at a higher risk of cytomegalovirus (CMV) colitis because of their immunocompromised status. There are no studies from Saudi Arabia regarding the prevalence of CMV colitis in patients with IBD. Objective: To determine the prevalence, characteristics, and risk factors of CMV colitis in patients with IBD in Riyadh, Saudi Arabia. Materials and Methods: This retrospective study included patients with a confirmed diagnosis of IBD (aged 14-75 years) who were followed up at King Fahad Medical City, a referral care center in Riyadh, between January 2016 and December 2021; patients with indeterminate colitis or incomplete medical records were excluded. Results: A total of 341 patients with IBD were included, of which 236 (72.2%) had Crohn's disease (CD) and 105 (27.8%) had ulcerative colitis (UC). Qualitative CMV PCR was done for 192 patients (60 UC and 132 CD patients), of which 14 patients were positive for CMV colitis (7.3%), and all positive CMV colitis cases were among UC patients (23.3%). However, the hematoxylin and eosin (H and E) stain and immunohistochemistry were negative for all patients. Most patients with CMV colitis were on steroids (71.4%), had at least one flare-up (64.3%), and were on biologic treatment (71.4%). Significant predictors of CMV colitis were hemoglobin (OR: 0.7; 95% CI: 0.51-0.96), albumin (OR: 0.88; 95% CI: 0.78-0.98), and C-reactive protein (OR: 1.03; 95% CI: 1.01-1.06) levels. Conclusion: This study found that the prevalence of CMV colitis was 7.3% among patients with IBD, and no case was diagnosed in patients with CD. In addition, as all cases diagnosed using qualitative CMV PCR were negative on H and E stain and immunohistochemistry, there is need for large-scale studies to improve the diagnosis of CMV colitis.
RESUMEN
Background: Cost, adverse events, and long treatment duration can be significant obstacles in treating hepatitis C virus (HCV)-infected individuals. Shortening the treatment regimen can minimize these barriers, thereby enhancing adherence and increasing medication availability to more patients. Methods: This is a single-centre, single-arm, open-label, phase 3 clinical trial on treatment naïve, non-cirrhotic, HCV genotype 4 patients. The study aimed to evaluate an 8-week course of Elbasvir (ELB)/Grazoprevir (GZR) in this population. The primary endpoint was sustained virologic response at 12 weeks after the end of treatment (SVR-12). The secondary endpoints were SVR-4, adverse events, and changes in health- and hepatitis-related quality of life (HRQoL). Results: Of the 30 patients who were enrolled, 29 (97%) achieved SVR-12 and SVR-4 (95% CI: 90-100%). No patients experienced serious or life-threatening adverse events (AEs), but mild/moderate AEs were reported by 16 (53%). The most commonly reported AEs were itching/skin rash (20%), headache (16.7%), abdominal/epigastric pain and decreased appetite (13.3% each), and nausea/vomiting (10%). Marked improvements in HRQoL were reported between the first (baseline) and third (SVR-12) timepoints. HRQoL score improvements involved the physical, mental, and hepatitis-specific indices, and ranged between 6 and 42 points (out of 100, P ≤0.003). Conclusion: The trial provides empirical evidence that HCV genotype 4-infected patients can achieve viral eradication with an 8-week-regimen of ELB/GZR. Further, this course of treatment is associated with a minimal adverse event profile and potentially significant improvements in quality of life. (ClinicalTrials.gov number, NCT03578640).

BACKGROUND: Peroral endoscopic myotomy (POEM) was proposed in 2010 as a minimally invasive procedure for the treatment of achalasia. In this article, we describe the Middle Eastern experience with the procedure in terms of efficacy, length of admission, and short- and long-term complications. METHODS: A retrospective analysis of our prospectively collected data on patients who underwent a POEM procedure was conducted between March 2019 and May 2020. The primary outcome was clinical success rate, defined as a postprocedure Eckardt score ≤3 at ≥3 months. Secondary outcomes included the length of hospital stay, presence of reflux symptoms or need for proton pump inhibitors (PPIs) ≥3 months, and adverse events. RESULTS: During the study period, 67 patients (35 females) underwent the procedure for achalasia. The participants' ages ranged from 11 to 80 years (mean 41 ± 18 years). Eckardt scores before the treatment ranged between 4 and 12 (mean 8.85 ± 1.75). Sixty-four patients (95.5%) achieved Eckardt scores of ≤3 at ≥3 months after the procedure (95% confidence interval [CI]: 91%-100%). The difference between pre- and post-procedural Eckardt scores averaged around -8 points (95% CI: -7.5 to -8.5 P < 0.0001). Adverse events were reported in 24 patients (35.8%) and included pneumoperitoneum (32.8%), reflux symptoms at 3 months (29.9%), and surgical emphysema (3%). Six patients had adverse events that led to prolongation of admission; 3% of whom had aspiration pneumonia, 3% had pneumoperitoneum, 1.5% had both, and 1.5% had an esophageal tear. CONCLUSIONS: POEM is a promising procedure for the treatment of achalasia with a high clinical success rate, short hospital admission, and a reassuring safety profile.

BACKGROUND AND STUDY AIM: Since its inception in 2007, single-operator cholangioscopy (SOC) has gained popularity for many diagnostically and therapeutically challenging biliary and pancreatic conditions. Many studies have been published to evaluate the feasibility, usefulness, cost-effectiveness, and safety profile of the first generation. This paper is a descriptive study in which we aim to share the experience of two tertiary care centers with the novel version of SOC, SpyGlass DS. PATIENTS AND METHODS: We retrospectively reviewed the records of all the patients who went through the procedure from October 2015 - July 2019 to explore the scope of biliary and pancreatic conditions in which SOC was utilized. Technical success was defined as the ability to visualize the lesion and complete the procedure as planned, whereas clinical success was determined by the ability to achieve the desired diagnostic/therapeutic outcome. RESULTS: During the period of interest, 66 patients (34 males) went through 84 cholangioscopy procedures. Forty-four patients failed the conventional extraction methods and needed the intervention for the treatment of difficult stones, 24 patients needed a diagnostic evaluation of biliary strictures, and 3 needed an intervention to remove migrated stents. Technical success was achieved in 98.8% (83/84) of the procedures (95% CI: 96-100%). Regarding clinical success, stone breakdown and removal was achieved in 92% of the procedures (49/53; 95% CI: 85-100%). Tissue samples were successfully obtained in 95.8% (23/24) of patients with strictures (95% CI: 88-100%). The biopsy was appropriate to make a histological diagnosis in 83.3% of cases (20/24; 95% CI: 68-98%). The median number of sessions needed to achieve the deisred outcome was one (ranging between 1 and 6 sessions). CONCLUSION: The new version of SOC, SpyGlass DS, provides a feasible and an effective option for the management of difficult cholelithiasis, as well as visually evaluating and obtaining histological samples for indeterminate biliary strictures. However, data from more extensive studies are needed to establish its non-inferiority to the fiberoptic version in terms of short- and long-term outcomes, cost-effectiveness, and complications.

BACKGROUND/AIM: Esophagogastroduodenoscopy (EGD) and Helicobacter pylori screening are routine parts of the preoperative assessment of patients undergoing bariatric surgery at many centers around the world. The reason for this step is to identify abnormalities that may change the surgical approach. In this study, we aim to evaluate the extent to which endoscopic findings and H. pylori testing affect the plan of care in bariatric patients. PATIENTS AND METHODS: We retrospectively reviewed the investigational processes of 356 patients planned for bariatric surgery (2014-2016) at our center. Patients were categorized into two main groups (4 subgroups) from endoscopic findings. One group included patients with normal EGD and patients who had abnormal findings that did not change the surgical approach, whereas the other included patients who had findings that changed or canceled the surgical plan. A logistic regression analysis was used to evaluate how strongly can factors such as patient demographics, BMI, comorbidities, symptomatology, and H. pylori status predict the risk of having plan-changing endoscopic abnormalities. RESULTS: The ages ranged between 15 and 66 years with a mean ± SD of 37 ± 11 years, and 56% were females. The majority of patients (75%; 95% CI: 73 - 82%) had either no findings (41%) or had abnormalities that did not change the surgical approach (34%). Only 25% (95% CI: 21-29%) were found to have pathologies that altered the surgical approach, and 0.6% of them had findings that were considered contraindications for surgery. In spite the relatively high prevalence of H. pylori in our cohort (41%; 95% CI 36-46%), the proportion of patients who had plan-changing abnormalities did not differ markedly from other studies. Gastroesophageal reflux disease (GERD) and obstructive sleep apnea symptoms were the only significant predictors of EGD findings (P = 0.009). CONCLUSIONS: GERD and sleep apnea symptoms can be strong predictors of EGD abnormalities. However, this evidence is still not enough to safely recommend changing the current practice. Therefore, until a sensitive clinical prediction score is derived and validated according to the symptoms, we suggest that EGD should continue as the standard of care in all patients undergoing bariatric surgery.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most technically demanding and high-risk procedures performed by GI endoscopists. Therefore, guidelines or position statements on various aspects of quality indicators, safety indicators and credentialing for ERCP have been developed by gastroenterology associations. In this paper, we evaluate the ERCP quality in a single, high-volume, tertiary care center in Saudi Arabia using a number of measures commonly stated by these organizations, and compare the experience of that center to the previously-published standards in this regard. PATIENTS AND METHODS: This is a descriptive, retrospective chart review of a consecutive sample taken over 12 continuous months (July 2016-June 2017). Data collected included demographic characteristics, and technical/clinical details from three time periods: preprocedure, intraprocedure, and postprocedure. Measurement parameters were all taken from the ASGE/ACG guidelines. Data was represented by the percentage of which each indicator was achieved, and the 95% proportion confidence intervals (CIs) when needed. RESULTS: From July 2016 to June 2017, 281 ERCP procedures were performed. An outstanding majority of them (95.7%) was done for therapeutic purposes, whereas 4.3% were diagnostic procedures. The sample included 206 patients, of whom 83 (40.3%) were males. The age of the participants ranged between 11 and 101â¯years (mean age⯱â¯SD; 51⯱â¯19). The quality of ERCP at the center in which the study was done met the performance targets stated by the ASGE/ACG for almost all indicators. Adverse events reported in our series were lower than previous studies for pancreatitis and perforation, and slightly higher in the incidence of bleeding, cholangitis, and death. CONCLUSION: In a single, high-volume, tertiary care center in Saudi Arabia, the quality of ERCP met the performance targets stated by the ASGE/ACG for almost all indicators.
