BACKGROUND AND OBJECTIVESThe epidemiology, clinical characteristics, and natural course of inflammatory bowel disease (IBD) in Saudi Arabia are still largely unknown. Hence, we decided to conduct a large retrospective, cohort study to determine these features of the disease.DESIGN AND SETTINGRetrospective study conducted in a tertiary care hospital in Riyadh from January 1970 to December 2008.PATIENTS AND METHODSWe reviewed all the cases of IBD diagnosed and collected all data pertaining to patients with IBD.RESULTSA total of 312 patients with IBD were included for this analysis, including 197 (63%) patients with Crohn disease (CD) and 115 (37%) patients with ulcerative colitis (UC). The mean age (standard deviation) of patients with IBD was 25.5 (10.6) years; 152 (48.7%) were males and 160 females. The referral rate in the past 10 years was 72.1% compared with preceding 20 years, and 56% (n=178) of patients with IBD were from the central region of Saudi Arabia. The patients were followed up for a mean duration of 9.5 years; during their follow-up, 206 patients (66%) required hospital admission and 9 patients (2.9%) with UC developed colon cancer. A total of 6 patients died during the follow-up. Fifty-three percent (n=104) of the patients with CD underwent surgeries as part of their treatment, whereas only 20% (n=23) of the patients with UC underwent colectomy.CONCLUSIONSThe incidence of IBD has been gradually increasing in Saudi Arabia over the years. Clinical features and morbidity in patients are not different from patients with IBD seen in the West.

BACKGROUND AND OBJECTIVES:Knowledge of the predictors of sustained viral response (SVR) to pegylated interferon (PEG-INF) alfa-2a and ribavirin (RBV) therapy in patients with hepatitis C genotype-4 (HCV-4) is crucial for selecting patients who would benefit most from therapy. We assessed the predictors of SVR to this combination therapy in Saudi patients with chronic HCV-4 infection.PATIENTS AND METHODS:This retrospective study included 148 patients with HCV-4 infection who underwent clinical, biochemical and virological assessments before treatment and at 12, 24, 48 and 72 weeks post-treatment.RESULTS:Of the 148 patients, 90 (60.8%) were males. Mean (SD) for age was 48.5 (12.7) years and BMI was 27.9 (7.5) kg/m2. Seventy-nine of 148 (60.1%) patients were treatment naïve and 110 (74.3%) underwent pre-treatment liver biopsy. Eighteen (12.2%) patients did not complete therapy because of side effects or they were lost to follow up. Early virological response was achieved in 84 of 91 (92.3%) patients. In the 130 (87.8%) patients who completed therapy, 34 (26.2%) were non-responders and 96 (63.8%) achieved end-of-treatment virological response (ETVR). SVR and virological relapse (24 weeks after ETVR) occurred in 66/130 (50.7%) and 30/130 (31.2%) patients, respectively. Compared to relapsers, sustained responders were significantly younger (P=.005), non-diabetic (P=.005), had higher serum albumin (P=.028), lower alpha-fetoprotein level (P=.026), lower aspartate aminotransferase (AST) (P=.04) levels, and were treatment-naivve (P=.008). In a multivariate regression analysis, the independent predictors of SVR were younger age (P=.016), lower serum AST (P=.012), and being treatment naivve (P=.021).CONCLUSION:Approximately half of HCV-4 patients who complete the course of combination therapy achieve an SVR, especially if they are young, treatment naivve and have lower AST levels.

BIB is a safe, simple, and potentially efficient procedure that is well-tolerated by the majority of patients.

Background/Aim:This retrospective study assessed the efficacy, safety, and the predictors of sustained viral response (SVR) to a 48-week-course of peginterferon α-2a (Pegasys) and ribavirin combination therapy in 335 consecutive Saudi patients with chronic hepatitis C virus (HCV) infection.Materials and Methods:Clinical, biochemical, and virological parameters were collected at time 0 (pretreatment) and at 12, 24, 48, and 72 weeks posttreatment. The mean ± SD age was 49.1 ± 13.0 years; 229 (68.4%) were males, mean ± SD body mass index was 27.8 ± 7.4, 85 (25.4%) were diabetic, 25 (7.5%) had renal impairment, 136 (40.6%) had previously received interferon ± ribavirin therapy, and 247 (73.7%) underwent pretreatment liver biopsy. Patients with genotypes 1, 2 or 3, 4 and mixed genotype were 60 (22.15%), 30 (11.0%), 148 (54.4%), and 34 (12.5%), respectively.Results:Early viral response (≥2-log10 HCV-RNA decline 12 weeks posttreatment) was achieved in 253 (75.3%). Patients who completed 48 weeks of treatment were 292 (87.1%); of these, 121 (75.6%) achieved ETVR, 161 (55.1%) continued to have SVR and 60 (20.5%) had a viral relapse following end-of-treatment response, that is 48.1 and 17.9% of all patients (n = 335), respectively. Nonresponders (NR) were 71 (24.3%) patients and 43 (12.8%) were unable to complete treatment (due to side effects or loss to follow up). Compared to the relapsers, patients with SVR were significantly younger (P = 0.000), nondiabetics (P = 0.015), had higher serum albumin (P = 0.007), had less pretreatment inflammatory grade (P = 0.011), infected with genotypes 2 or 3 (P = 0.014), and treatment-naïve patients (P = 0.001). However, in stepwise multivariate logistic regression analysis, only treatment naiveté and low pretreatment inflammatory score were the independent predictors of SVR (P = 0.005 and P = 0.018, respectively).Conclusion:Combination therapy, if tolerated and completed, is effective in treating chronic HCV patients, especially those with no previous interferon therapy and lower pretreatment inflammatory grade.

Background: The Kingdom of Saudi Arabia (KSA) was the first country in the Middle East to adopt the hepatitis B virus (HBV) vaccine. Despite an expanded HBV immunization program and significant progress in HBV prevention in the country, HBV infection is a significant public health burden. This review lists coordinated solutions for healthcare stakeholders, patients, and health authorities to curb HBV and its impact in KSA. It further aims to draw policymakers' attention to key priorities to bridge HBV care gaps in the country.Methods: As part of the pre-engagement activity, medical experts across KSA were interviewed to gain a preliminary understanding of the current unmet needs in HBV management in the country. Toprecommended action points derived from the pre-engagement activity were discussed. Key priority action points to curb the impact of HBV in KSA were identified.Results: The priority action points together with the challenges and unmet needs in the management and care of HBV in KSA were: (a) establish a national-level registry, (b) implement screening campaigns, (c) improve linkage of care between primary care physicians (PCPs) and specialists, and (d) increase PCP education and awareness. Conclusion:This work is an endeavor to set the stage for a strategic policy framework aimed at eliminating HBV in KSA. The action points/steps for the identified priorities must run parallelly across various regions in KSA, to successfully manage and further eliminate the threat of HBV.

BACKGROUND AND OBJECTIVESWilson disease (WD) is a rare autosomal recessive disease. Our objective was to describe the diverse patterns, therapies, and outcomes of this disease.DESIGN AND SETTINGA retrospective study over two decades on WD patients in a tertiary care center in Saudi Arabia.PATIENTS AND METHODSClinical and laboratory findings of 71 patients with WD were retrieved from their charts, referral notes and our hospital electronic records and were analyzed.RESULTSThe mean age and standard deviation was 16.8 (10.7) years and 56.5% were males. The main manifestations of WD were hepatic, neurological, and mixed in 39 (54.9%), 12 (16.9%), and 20 (28.2%) patients, respectively, and 11 (15.5%) were asymptomatic cases detected by family screening. A family history of WD was positive in 41 (57.7%) patients, and consanguinity of parents was found in 26 (36.6%) patients. The mean (SD) follow-up period was 92.2 (72.9) (range, 1–320) months. Ten (14.1%) patients died during follow up, while 45 (63.4%) and 16 (22.5%) were still on or lost from follow-up, respectively. The mean (SD) age at the end of follow-up was 25.3 (12) (range, 4–62) years. Hepatoma was discovered in 5 (7.0%) patients. Penicillamine therapy was used by 58 (81.7%) patients, while zinc and trientine were given to 32 (45.1%) and 11 (15.5%) patients, respectively. Sixteen (22.5%) patients underwent liver transplantation and one died (1.4%) on the waiting list. The liver condition remained stable or improved in 35 (49.3%), and the neurological status showed improvement in 11 (34.4%) of the 32 patients who had neurological involvement.CONCLUSIONSThis is the biggest cohort to be reported from the Middle East. WD presentation and outcome of WD are very diverse, and its diagnosis still depends on clinical, laboratory, and radiological evidence of abnormal copper metabolism. WD should be considered in patients of any age with obscure hepatic and/or neurological abnormalities.
