BackgroundHepatocellular carcinoma (HCC) is one of the leading causes of death in Saudi male patients. Local clinical and demographic data of this disease are scarce.ObjectivesWe sought to describe the clinical characteristics and outcomes of patients from two tertiary care centers in Saudi Arabia.Patients and MethodsData were collected for all patients diagnosed to have hepatocellular carcinoma between June 2003 and July 2008 who had been registered in a special research database (the Saudi Observatory Liver Disease Registry (SOLID)). Data were extracted from SOLID for clinical, biochemical, radiologic parameters and outcome.ResultsData was available for 363 patients, the mean age of diagnosis was 66 years, 74% of patients were males, and Hepatitis C was the underlying cause of liver disease in 48%, while Hepatitis B in 29%. Most of the patients were diagnosed at an advanced stage, 53 % of patients had a CLIP score of 4 to 6 (advanced stage), 55% had large multi-nodular tumors and 16% had vascular invasion or extra-hepatic spread at the time of diagnosis. Most of the patients had decompensated cirrhosis; with child-pogh score B in 44% and C in 26% with presence of portal hypertension in 55%. Forty eight percent died during the study period. Predictors of poor survival in the univariate analysis were; presence of portal vein thrombosis (P = 0.03), portal hypertension (P < 0.0001), presence of ascites (P = 0.022), hepatic encephalopathy (P < 0.0001), advanced child-pough score (P < 0.0001), bilirubin > 22 (P < 0.0001) and INR > 1.2 (P = 0.02). On multivariate analysis, only the presence of portal hypertension, bilirubin > 22 and severe hepatic encephalopathy were significant with adjusted hazard ratio of 1.6 (95% CI; 1.04-2.47), 1.76 (95% CI; 1.12-2.8), and 3.18 (95% CI; 1.42-7.14) respectively.ConclusionsThe data from this cohort indicates that most of patients diagnosed with HCC present at late tumor and liver disease stages, when prognosis is usually dismal. Regular cancer surveillance in cirrhotic patients might change the outcomes. Further studies with results of treatment outcomes in this community are needed.

BACKGROUNDThe estimated prevalence of nonalcoholic fatty liver disease (NAFLD) in Saudi Arabia is 7% to 10%. Despite the high prevalence of risk factors including diabetes, obesity, and hyperlipidemia, no recent epidemiological studies have measured the disease burden. We aimed to determine the characteristics of Saudi NAFLD patients attending a university hospital, and study factors affecting alanine aminotransferase (ALT) levels.DESIGN AND SETTINGA prospective study among patients referred for ultrasonography in King Khalid University Hospital in Riyadh, Saudi Arabia from February to May 2009.PATIENTS AND METHODSNAFLD was defined as an appearance of fatty liver on routine abdominal ultrasound in the absence of coexisting liver disease and alcohol consumption. Patients were classified into normal and high ALT (ALT >60 U/L) level groups for analysis.RESULTSThe prevalence of NAFLD was 16.6% (218/1312). Patients with normal ALT had the mean (SD) age of 45.9 (10.6) years and the mean body mass index of 34.5 (7.9) kg/m2. Forty percent of the 151 patients with normal ALT had diabetes, 66.2% were obese, and 29.1% had hypertension. Forty-three patients (23%) had high ALT levels. These patients had significantly lower age (P=.003) and fasting blood sugar (P=.03) than the normal ALT group. Non-diabetic patients (odds ratio 0.30, 95% CI 0.1–0.8), men (female OR 0.23, 95% CI 0.1–0.5), lower cholesterol (P=.001), high-density lipoprotein (P=.006), and low-density lipoprotein (P=.008) levels were more likely to be observed among patients with high ALT levels. In a multivariate analysis, younger age (OR 0.96, 95% CI 0.93–0.99), being male (OR 0.23, 95% CI 0.09–0.57), and a lower cholesterol level (OR 0.55, 95% CI 0.37–0.82) were significant predictors of high ALT levels.CONCLUSIONBased on the high prevalence of obesity and diabetes, the prevalence of NAFLD will continue to be high, unless awareness is inculcated among the local population.

Background: Diabetes mellitus is one of the leading causes of end stage renal disease. Use of intraperitoneal (IP) nsulin in diabetic patients on peritoneal dialysis (PD) can restore glucose control to near normal values. The safety and efficacy of this method is unclear. Methods: We performed a meta-analysis to study the safety and efficacy of IP insulin administration in diabetic patients on PD. The primary outcome measures is glycemic control: secondary outcome measures were plasma lipids, insulin dose requirement/day and the risk of peritonitis and hepatic subcapsular steatosis. Medline, EMBASE, Cochrane Central Register of Controlled Trials, and reference lists of eligible studies were searched. Eligible studies included randomized and non-randomized controlled trials that allocated adult PD diabetic patients to IP insulin and subcutaneous (SC) insulin. Results: Twenty one citations were identified and three met the eligibility criteria. Glycemic control with IP insulin, as assessed with HbA1C, was equal to or better than that obtained with SC insulin: weighted mean difference was −1.49 % (95% CI: -2.17 to - 0.27, p=0.0001). The insulin dose required was more than two-fold higher in the IP treatment. Serum HDL-cholesterol decreased during IP insulin therapy while serum triglyceride (TG) concentration tended to increase, in comparison with levels seen in patients treated with SC insulin. Conclusions: Use of IP insulin provides adequate glycemic control, which appears superior to that seen following treatment with conventional SC insulin. The plasma lipids are adversely affected by IP insulin, possibly contributing to increased cardiovascular risk. Data are limited and further studies are needed to assess for the long-term safety of this approach.

The use of complementary and alternative medications (CAM), products, and therapies not considered to be part of conventional medicine is common among patients with inflammatory bowel disease (IBD). Patients often turn to these therapies as they are considered natural and safe, with significant benefit reported beyond disease control. There is emerging evidence that some of these therapies may have anti-inflammatory activity; however, robust evidence for their efficacy in modulating disease activity is currently lacking. Patients often avoid discussing the use of CAM with their physicians, which may lead to drug interactions and/or reduced adherence with conventional therapy. It is important for physicians to be aware of the commonly used CAM and current evidence behind these therapies in order to better counsel their patients about their use in the management of IBD. This narrative review provides an overview of the evidence of the more commonly used CAM in patients with IBD.

Background: Crohn's disease (CD) frequently recurs after intestinal resection. Azathioprine (AZA) and biological therapies have shown efficacy in preventing postoperative recurrence (POR). Data on POR from Middle Eastern populations is lacking. This study aimed to evaluate the rate of endoscopic POR in a cohort of CD patients who underwent ileocecal resection (ICR), and to assess the effectiveness of AZA and biological therapies in reducing the risk of disease recurrence. Methods: We performed a retrospective cohort study on 105 CD patients followed at our center, who underwent ileal resection and were at moderate to high risk for POR. Clinical and laboratory data were collected; the primary endpoint was post ICR endoscopic recurrence at 24 months defined by Rutgeerts' score of i2 or more despite treatment. Results: In total, 105 patients with Crohn's disease met our inclusion criteria; 76.2% were in remission and did not have endoscopic POR at 24 months. Further, 41.9% were on biological therapy, and 34.3% were mainly on AZA. Out of the 28.2% who had POR, approximately 15% were on biological therapies. Penetrating phenotype was the only predictive factor for decreasing POR (OR = 0.19, 95% CI: 0.04–0.98, P = 0.04) as identified in multiple logistic regression analysis. Conclusions: The use of biological therapies post-surgery was not superior than AZA in reducing the endoscopic POR for mod- high risk CD patients. Only penetrating behavior of the CD was associated with significantly lower risk of endoscopic recurrence. This finding is worth further investigation in more robust study designs and among larger samples of patients.

Gastroesophageal reflux disease (GERD) occurs in approximately two-thirds of all pregnancies. Around 25% of pregnant women experience heartburn daily. Symptomatic GERD usually presents in the first trimester and progresses throughout pregnancy. The treatment goal is to alleviate heartburn and regurgitation without jeopardizing the pregnancy or its outcome. An English language electronic literature search of MEDLINE, EMBASE, and Cochrane Reviews was undertaken to identify randomized controlled trials, observational studies, management recommendations and reviews of GERD and its treatment during pregnancy. The search period was defined by the date of inception of each database. The treatment in a pregnant GERD patient should follow the step-up approach, starting with lifestyle modification as the first step. If heartburn is severe, medication should be started after consultation with a physician (Recommendation Grade C). The preferred choice of antacids is calcium-containing antacids (Recommendation Grade A). If symptoms persist with antacids Sucralfate can be introduced at a 1g oral tablet, 3 times daily (Recommendation Grade C). Followed by histamine-2 receptor antagonist (Recommendation Grade B). Inadequate control while on histamine-2 receptor antagonist and antacid may mandate a step-up to proton pump inhibitors along with antacids as rescue medication for breakthrough GERD (Recommendation Grade C). This article presented the treatment recommendations for pregnant women with typical GERD, based on the best available evidence.Abbreviations: GERD = gastroesophageal reflux disease, GRADE = grading evidence and strength of recommendation guidelines, H2RA = histamine-2 receptor antagonist, LES = lower esophageal sphincter, PPI = proton pump inhibitor, RCT = randomized clinical trial.

Background Trauma is considered a significant public health problem worldwide. Abdominal trauma is generally divided into blunt and penetrating. Blunt trauma could affect any organ, and the sequelae of such injury may not always be clinically apparent. Liver injury is one of abdominal trauma's most critical and fundamental complications. We aimed to investigate the mechanism, type, and extent of injuries for patients with liver trauma and compare the outcomes between operative and non-operative management. Methods This retrospective study analyzed data of patients with liver injuries who presented to King Khalid University Hospital, King Saud University from 2016 to 2022. Management included conservative, conservative to laparotomy, laparotomy, and interventional radiological procedures, including hepatic artery angioembolization and percutaneous transhepatic drainage. Injury severity was graded based on the American Association for the Surgery of Trauma (AAST) liver injury scale. Results We analyzed 45 liver injury patients, with mean age of 29.3 years and most of them being male (77.8%). The most common injury mechanism was blunt trauma (86.7%), whereas penetrating injuries accounted only for 8.9% of cases. The most dominant type of injury was laceration (95.6%), followed by contusion (28.9%). Regarding liver injury severity, the majority of patients (37.8%) had a grade 3 injury level as per AAST liver injury scale. Among all patients, 31 (68.9%) were hemodynamically stable, whereas 14 patients (31.1%) were unstable, with a mortality rate of 2.2%. Most patients (82.2%) underwent conservative management. Six patients (13.3%) require surgical laparotomy. Two patients (4.4%) who underwent conservative management first needed surgical laparotomy. The complication rate was 24.4%, with delirium being the most common (6, 13.3%), followed by fever and sepsis (3, 6.7%) and acute renal failure, pneumonia, cardiac arrest, biliary leaks, meningitis/seizures, which were all reported in a subset of patients. Conclusions Liver trauma is considered a significant public health problem worldwide. The management of traumatic liver injuries has evolved significantly over the years, with the addition of interventional radiological modalities, a more inclined approach toward non-operative management.
