RESUMO
ABSTRACT: Eosinophilic esophagitis is an antigen-mediated chronic inflammatory disorder that has risen in incidence and prevalence over the past 2 decades. The clinical presentation is variable and consists of mainly esophageal symptoms such as dysphagia, heartburn, food impaction, and vomiting. Current management relies on dietary elimination, proton-pump inhibitors, and topical corticosteroids with different response rates and relapses after treatment discontinuation. With a better understanding of the underlying pathophysiology, many molecules emerged recently as targeted treatment including dupilumab (IL4/IL13 blocker), as the first FDA-approved biological treatment, which has changed the management paradigm.

This account details the case of a 39-year-old male patient who presented with acute necrotizing hemorrhagic pancreatitis. The comorbid conditions of Wernicke's encephalopathy, and a pancreatic-colonic fistula developed during his care. This case is unique in that it illustrates the effects of these complications individually and through their interaction. Given that there are no firm guidelines regarding the nature and timing of interventions for a pancreatic-colonic fistula diagnosis, this case may provide helpful information. Case Presentation: As previously noted, this is the case of a 39-year-old male patient with a BMI of 46 kg/m2 who presented with acute necrotizing hemorrhagic pancreatitis. Complications developed as noted above. Multiple diagnostic imaging methods were utilized but failed to detect the presence of metastatic pancreatic adenocarcinoma. After a course of antimicrobial and nutritional therapy, we attempted surgical intervention for the pancreatic-colonic fistula and pancreatic abscess debridement. Unfortunately, during that procedure, we observed extensive carcinomatosis, at which point we did a gastrojejunostomy. Subsequently, the patient's condition did not permit chemoradiotherapy. After completion, we transferred the patient to palliative care, where he died. Clinical Discussion: This case was complex due to the previously recounted results of the underlying condition, pancreatic adenocarcinoma, and the complications of Wernicke's encephalopathy and pancreatic-colonic fistula. The presence of risk factors in patients increases the need to perform appropriate diagnostic tests. Even with tests and multiple imaging modalities, these particular events remain challenging to diagnose, given the nature of the development and presentation of the disease condition. It was only after the surgical intervention that the carcinoma became evident. Early screening and imaging could improve detection rates and prevent disease progression. Conclusion: In this case report of acute hemorrhagic necrotizing pancreatitis and its complications, we discuss the factors making this disease process particularly difficult to diagnose, detect, and manage. Even though the complications detailed herein are rare, in this case, the significance is the need to evaluate all patients with acute pancreatitis and acute confusion for Wernicke's encephalopathy, which is preventable. In addition, suggestive findings on computed tomography signal the need for further investigation of the colonic fistula. Finally, at this time, there are no clear guidelines for the surgical management of these complications. We hope that this case report will contribute to their development.
RESUMO
The eradication rates for Helicobacter pylori globally are decreasing with a dramatic increase in the prevalence of antibiotic resistant bacteria all over the world, including Saudi Arabia. There is no current consensus on the management of H. pylori in Saudi Arabia. The Saudi Gastroenterology Association developed these practice guidelines after reviewing the local and regional studies on the management of H. pylori. The aim was to establish recommendations to guide healthcare providers in managing H. pylori in Saudi Arabia. Experts in the areas of H. pylori management and microbiology were invited to write these guidelines. A literature search was performed, and all authors participated in writing and reviewing the guidelines. In addition, international guidelines and consensus reports were reviewed to bridge the gap in knowledge when local and regional data were unavailable. There is limited local data on treatment of H. pylori. The rate of clarithromycin and metronidazole resistance is high; therefore, standard triple therapy for 10-14 days is no longer recommended in the treatment of H. pylori unless antimicrobial susceptibility testing was performed. Based on the available data, bismuth quadruple therapy for 10-14 days is considered the best first-line and second-line therapy. Culture and antimicrobial susceptibility testing should be considered following two treatment failures. These recommendations are intended to provide the most relevant evidence-based guidelines for the management of H. pylori infection in Saudi Arabia. The working group recommends further studies to explore more therapeutic options to eradicate H. pylori.

Background: Primary biliary cholangitis (PBC) is a progressive autoimmune cholestatic liver disease that primarily affects females more than males and may lead to end-stage liver disease. We studied baseline characteristics, and the biochemical and clinical response to ursodeoxycholic acid (UDCA), a first-line treatment option for patients with PBC, in a cohort of patients diagnosed with PBC from Saudi Arabia. Methods: A total of 30 patients meeting the diagnostic criteria of PBC who were being followed in the King Faisal Specialist Hospital and Research Centre in Riyadh, Saudi Arabia, between January 1, 2008, and December 31, 2017, were enrolled in the study. The patients with autoimmune hepatitis, primary sclerosing cholangitis, and overlap syndromes were excluded. The baseline characteristics of the patients were recorded. The response to UDCA treatment was assessed according to the Barcelona, Paris I, Paris II, and Toronto criteria, and clinical outcomes, and biochemical changes were ascertained. Results: The mean age was 46 years ± 11.7 with a female gender predominance of 93% (n = 28). Pruritus was the predominant symptom reported by 90% (n = 27) of the patients. A total of 23 (77.7%) patients underwent liver biopsy and all of them showed histological features suggestive of PBC. Cirrhosis was documented in 30% (n = 9) of the patients at baseline. Overall, 86.7% (n = 26) of the patients were positive for antimitochondrial antibodies. The biochemical response rates to UDCA based on Paris I, Paris II, Barcelona, and Toronto criteria were 73.3, 40, 56.7, and 53.3%, respectively. Conclusion: Over 10 years, 30 patients with PBC were diagnosed at a large referral center in Saudi Arabia. The response to UDCA treatment was inadequate.

Background: Progressive familial intrahepatic cholestasis (PFIC) is a rare genetic disorder that results from defective mechanisms of bile secretion. We aim to describe different types of PFIC and their clinical features, treatment modalities, and outcomes in Saudi Arabia. Patients and Methods. This is a retrospective study of all patients diagnosed with PFIC at King Faisal Specialist Hospital and Research Center in Riyadh from January 1, 2002, to December 31, 2021. All relevant information was collected from patient charts and transferred into the REDcap® database for statistical analysis. Results: A total of 79 patients were identified with PFIC, and PFIC type 3 was the most common (59.5%), followed by PFIC type 2 (34.2%), PFIC type 1 (5.1%), and PFIC type 4 (1.3%). Males and females were affected in 54.4% and 45.6%, respectively. Mutations in ATP8B1, ABCB11, and ABCB4 genes were observed in PFIC type 1, PFIC type 2, and PFIC type 3, and loss of function in a variant of TJP2 was detected in PFIC type 4, respectively. A total of 51 (64.6%) patients underwent liver transplantation: three patients (3/4) with PFIC type 1 (75%), twenty patients (20/27) with PFIC type 2 (74.1%), twenty-seven patients (27/47) with PFIC type 3 (57.4%), and one patient with PFIC type 4 (100%). The mean duration of disease before transplantation was 53.9 ± 67 months with a median of 30 months. Following liver transplantation, symptomatic control was achieved in 47 patients (92.2%). Recurrence after transplantation occurred in 4 patients (7.8%) within an average of 22.5 months and a median of 17 months. Conclusion: PFIC is considered a rare disorder in Saudi Arabia; however, early recognition of the disease is important for appropriate management and early referral for liver transplantation evaluation. The overall rate of liver transplantation in our cohort was 64.6% with an excellent five-year survival rate.
RESUMO
The incidence of gallstone spillage and gallbladder perforation has increased as a result of the rising use of laparoscopic cholecystectomy. The presence of gallstones in the abdomen may lead to adhesions, inflammation, infection, and obstruction of biliary ducts. Since different etiologies can occur with spillage of gallstones, variation in presentation is expected. We report a case of a laparoscopic cholecystectomy complication after four years of surgery. The patient's clinical presentation mimicked malignancy.
RESUMO
BACKGROUND/AIM: The treatment efficacy of Helicobacter pylori (H. pylori) has been decreasing over time due to resistance to multiple antimicrobial therapies. The most effective treatment regimen for Saudi Arabian patients infected with H. pylori is still unknown. We aimed to study the eradication rate of 10 days of quadruple therapy; bismuth subcitrate potassium 140 mg, metronidazole 125 mg, and tetracycline 125 mg for H. pylori infection in a Saudi population. PATIENTS AND METHODS: This was a prospective, open-label, non-randomized controlled trial. Patients with H. pylori infection were diagnosed by upper gastrointestinal (GI) endoscopy and rapid urease test (RUT) or histology. Patients who tested positive were recruited. Eligible patients were prescribed a 10-day course of quadruple therapy and received three capsules 4 times daily for 10 days along with omeprazole 20 mg twice daily. H. pylori was considered eradicated if the urea breath test (UBT) was negative after 6 weeks of completing the treatment. RESULTS: Ninety-two patients with H. pylori infection were recruited. Three patients withdrew from the trial and another seven patients lost follow-up. We analyzed 82 patient's data as per-protocol analysis, of whom 66 (80%) were naive to H. pylori treatment. Four patients had failed previous treatment with the sequential regimen and 12 patients had treatment with clarithromycin-based triple therapy. The post-treatment UBT for H. pylori infection was negative by per-protocol analysis in 72/82 patients (87.8%), and 72/92 (78.3%) by intention-to-treat analysis. There was no correlation between previous treatment failure and treatment response to the bismuth-based quadruple therapy (P value = 0.28). CONCLUSIONS: Treatment with a bismuth-based quadruple therapy was effective in eradicating H. pylori infection in 78.3% of Saudi patients with an ITT analysis and in 87.8% as per-protocol analysis.

Diffuse involvement of the gastrointestinal tract by graft versus host disease (GVHD) is a common complication of allogeneic hematopoietic stem cell transplant (HSCT). Gastrointestinal GVHD usually presents 3 or more weeks after HSCT and is characterized by profuse diarrhea, anorexia, nausea, vomiting, abdominal pain and gastrointestinal bleeding. We report a case of a 23-year-old male who had undergone allogeneic HSCT and presented with bloody diarrhea on the 90th day post-HSCT. On the fourth day of admission, the patient passed per rectum a 27-cm long pinkish colored fleshy material recognized as a "colon cast". Sigmoidoscopy showed a congested and erythematous rectum with the remaining portion of the "colon cast" attached to the proximal part of the sigmoid colon. A biopsy from the rectal wall was suggestive of grade IV GVHD. The patient was treated with methylprednisolone, cyclosporin and mycophenolate mofetil, with a partial response (diarrhea and abdominal pain improved), but then he developed multiple other medical complications and died after 3 months.

Intragastric balloon (IGB) placement for the treatment of obesity has been in use for more than three decades. The major advantage of IGBs is that they preserve the anatomy of the stomach and are generally considered safe; the most common complications are nausea/vomiting and abdominal pain, and very rarely are IGBs associated with mortality (0.05%). A total of 14 cases of pancreatitis complicating IGBs have been reported in the literature. In this series, we reported 10 patients who developed acute pancreatitis in association with IGBs of which half were treated conservatively without the removal of the IGBs.

Mitochondrial neurogastrointestinal encephalomyopathy syndrome is a rare autosomal recessive multisystem disorder caused by nuclear TYMP gene mutations, which leads to deficiency in thymidine phosphorylase enzyme. This deficiency then leads to mitochondrial dysfunction, which causes the features characteristic of this syndrome, including severe muscle wasting, gastrointestinal dysmotility, leukoencephalopathy, peripheral neuropathy, and ophthalmoplegia. Here, we present a case series of 3 patients with mitochondrial neurogastrointestinal encephalomyopathy from Saudi Arabia who underwent allogeneic stem cell transplant at King Faisal Specialist Hospital (Riyadh, Saudi Arabia). Two patients died within the first year of transplant, and the third is still alive but without improvement in clinical features. Allogeneic hematopoietic stem cell transplant-related mortality appears to be high; this may at least be partially related to established end-organ effects with decreased performance status. Although allogeneic hematopoietic stem cell transplant clearly affects correction of genetic and biochemical defects in mitochondrial neurogastrointestinal encephalomyopathy, its ability to reverse or improve established clinical manifestations has not been proven.

Hepatic hydrothorax (HH) is a transudative pleural effusion that complicates advanced liver cirrhosis. Cases refractory to medical treatment in the form of salt restriction and diuretics are labeled refractory hepatic hydrothorax (RHH) and may require transjugular intrahepatic portosystemic shunts (TIPSS) or even liver transplantation. Renal impairment is common in advanced liver disease, worsens its prognosis, and makes the management of HH more challenging. Successful antiviral therapy reduces some of the complications of cirrhosis secondary to hepatitis C virus (HCV) infection. We herein report two cirrhotic patients with chronic kidney disease who developed RHH which resolved after the successful treatment of their HCV infection with direct-acting antivirals (DAAs). In cases of RHH associated with HCV cirrhosis, a trial of DAAs is warranted before resorting to TIPSs or liver transplantation.
RESUMO
BACKGROUND/AIMS: The ideal end point of treatment for chronic hepatitis B virus (HBV) infection is sustained off-therapy hepatitis B surface antigen (HBsAg) loss with or even without seroconversion to anti-HBs. We investigated the role of adding PEGylated interferon (PEG IFN) to ongoing tenofovir treatment in chronic HBV patients for achieving HBsAg clearance. PATIENTS AND METHODS: In this randomized controlled trial, chronic HBV patients who have been receiving tenofovir for >6 months with HBV viral load <2000 IU/ml were randomized into two groups. One group (add-on therapy) was given subcutaneous PEG IFN 180 mcg weekly for 12 months in addition to tenofovir. Patients in the other group received only tenofovir 300 mg orally on a daily basis. Patients in both groups were followed up for a total of two years, and patients in both groups were given tenofovir 300 mg daily indefinitely until they developed HBsAg clearance. RESULTS: Twenty-three patients were allocated to the PEG IFN and tenofovir (add-on therapy) group, and another 25 patients were recruited to the tenofovir monotherapy group. Before randomization, patients had received tenofovir for 1135 mean days (range203 to 1542 days). One patient (4.3%) in add-on therapy lost HBsAg and seroconverted. Within two years, mean HBsAg decreased significantly with add-on therapy (from 4753 IU/ml to 2402; P= 0.03); and it decreased from 5957 IU/ml to 4198; P= 0.09 in tenofovir monotherapy group. More patients in the add-on group developed serious side effects, with treatment discontinuation, and dose reductions (P = 0.3). CONCLUSION: PEG IFN and tenofovir add-on therapy was successful in achieving HBsAg clearance and seroconversion in 4.3% of the patients. Add-on therapy patients had a significant decrease in HBsAg levels in two years; and no significant decrease in HBsAg levels with the tenofovir monotherapy. With no significant HBsAg clearance, the utility of this combination regimen is questionable.

Optimal doses of Ribavirin (RBV) for hepatitis C virus (HCV) treatment are not known. To assess the safety and efficacy of PegIFNalfa-2a in combination with an adjusted (ADJ) RBV dose based on early pharmacokinetics versus a fixed standard (STD) dose of RBV in chronic HCV genotype (GT) 4-naive patients in a randomized trial. One hundred eighty-one patients were randomized. The baseline variables were similar in both arms and females were 50.3% of the patients, 76.5% had minimal-moderate fibrosis (F0-2). Sustained virologic response (SVR) was achieved in 99 (54.7%) subjects. SVR was seen in 50/90 (55.6%) of ADJ dose of RBV and 49/91 (53.9%) of STD dose subjects. Prematurely withdrawal or discontinuation of treatment prematurely in the ADJ RBV arm occurred in 11/90 patients (12.2%) compared with 6/91 subjects (6.6%) in the STD arm (P = 0.214). Similarly, virologic relapse was seen in 14/90 (15.6%) patients of the ADJ arm and 12/91 (13.2%) of the STD arm. Anemia grade 3-4 was seen in 36.7% in ADJ versus 17.6% in STD arm (P = 0.003). Occurrence of rapid virologic response and absences of F4 fibrosis predicted SVR in a univariate analysis. However, age, gender, weight, presence of diabetes, baseline alanine aminotransferase, and vitamin D levels were not significantly different in patients achieving SVR. ADJ higher doses of RBV based on its early pharmacokinetics-based RBV do not improve SVR rates in HCV GT4 treated in combination with peg-IFN alpha-2-a versus STD therapy. Patients on ADJ higher doses of RBV experienced higher rates of anemia and require more erythropoietin without increasing SVR.

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a rare autosomal recessive disorder. The mutation in the ECGF1 gene causes severe deficiency of thymidine phosphorylase (TP), which in turn increases thymidine and deoxyuridine in the blood, serum, and tissue. The toxic levels of these products cause malfunction of the mitochondrial respiratory chain and mitochondrial DNA. Commonly, patients become symptomatic between 15 and 20 years of age (range 5 months to 35 years). The most commonly affected systems are gastrointestinal, followed by ocular, and nervous system. The disease is often fatal; high mortality rate is reported between 20 and 40 years of age. Treatment modalities that can increase thymidine phosphorylase activity and decrease thymidine and deoxy-uridine have shown symptomatic improvements in patients with MNGIE. Platelet transfusion, hemodialysis, peritoneal dialysis or allogeneic hematopoietic stem cell transplantation (HSCT) have been tried. The survival and long-term benefits of these measures are still not clear. Engrafted patients after stem cell transplantation have showed improvements in serum thymidine and deoxyuridine. We are reporting a case of MNGIE from Saudi Arabia, who underwent allogeneic hematopoietic stem cell transplantation. No MNGIE case has been previously reported from Saudi Arabia or the Gulf Arab countries. From the available literature, so far only 11 patients with MNGIE have undergone stem cell transplantation.

BACKGROUND/AIMS: Treatment success for Helicobacter pylori infection in Saudi Arabia is relatively unexplored. This prospective study compared the efficacy of sequential versus standard triple therapy in curing H. pylori infections. PATIENTS AND METHODS: Eligible patients underwent upper endoscopy at a single center in Saudi Arabia from October 2011 to February 2014. Patients who tested positive for H. pylori infection were randomly assigned to sequential therapy or standard triple therapy. Sequential treatment: Esomeprazole (20 mg bid for 10 days), amoxicillin (1000 mg for 5 days), then clarithromycin 500 mg and tinidazole 500 mg; both bid for 5 days. Standard triple treatment: Esomeprazole 20 mg, clarithromycin 500 mg, and amoxicillin 1000 mg each bid for 14 days. After 6 weeks of treatment, patients were tested for cure using a validated urea breath test. Application of the E-test determined susceptibility of H. pylori to different antibiotics. RESULTS: Of the 115 patients who received sequential therapy, 93 completed treatment. In the triple-therapy arm, 103 of 117 patients completed treatment. The eradication rate was 58/93 (62.3%) with sequential therapy and 69/102 (67.6%) with standard triple therapy, P = 0.44. Risk ratio was 0.92 (95% CI; 0.75-1.13), and number needed to treat was 19. Overall primary resistance: Metronidazole (48.5%), clarithromycin (23.3%), amoxicillin (14.8%), levofloxacin (11.1%), and tetracycline (2.3%). Mild adverse events occurred in 35 and 17 patients in the sequential and standard therapy groups, respectively. CONCLUSION: Sequential and standard triple therapies were similarly effective at eradicating H. pylori in two-thirds of Saudi patients. Metronidazole and clarithromycin resistance to H. pylori strains was common.

BACKGROUND: First-line levofloxacin-based treatments eradicate Helicobacter pylori with varying success. We examined the efficacy and safety of first-line levofloxacin-based treatment in comparison to standard first-line therapy for H pylori eradication. MATERIALS AND METHODS: We searched literature databases from Medline, EMBASE, and the Cochrane Register of Randomized Controlled Trials through March 2013 for randomized controlled trials comparing first-line levofloxacin and standard therapy. We included randomized controlled trials conducted only on naïve H pylori infected patients in adults. A systematic review was conducted. Meta-analysis was performed with Review Manager 5.2. Treatment effect was determined by relative risk with a random or fixed model by the Mantel-Haenszel method. RESULTS: Seven trials were identified with 888 patients receiving 7 days of first-line levofloxacin and 894 treated with standard therapy (Amoxicillin, Clarithromycin and proton pump inhibitor) for 7 days. The overall crude eradication rate in the Levofloxacin group was 79.05% versus 81.4% in the standard group (risk ratio 0.97; 95% CI; 0.93, 1.02). The overall dropout was 46 (5.2%) in the levofloxacin group and 52 (5.8%) for standard therapy. The dizziness was more common among group who took Levofloxacin based treatment and taste disturbance was more common among group who took standard therapy. Meta-analysis of overall adverse events were similar between the two groups with a relative risk of 1.06 (95% CI 0.72, 1.57). CONCLUSION: Helicobacter pylori eradication with 7 days of Levofloxacin-based first line therapy was safe and equal compared to 7 days of standard first-line therapy.

BACKGROUND AND OBJECTIVES: Entecavir is a nucleoside analog used in the treatment of chronic hepatitis B. The efficacy of ETV has not been studied in the Saudi population. The objective of the study was to find undetectable HBV DNA after 48 weeks completion of ETV treatment in real-life versus clinical trial patients. DESIGN AND SETTING: A retrospective study in a tertiary care center in Saudi Arabia of patients treated from 2006 January to 2010 June. PATIENTS AND METHODS: Of 43 eligible patients, 24 patients were treatment-naïve and 19 were treatment refractory. RESULTS: Mean HBV DNA viral load was 51 million IU/mL prior to treatment and decreased to 0.16 million IU/mL at 48 weeks. Mean HBV DNA log10 IU/mL was 6.3 before treatment and decreased to 2.3 log10 IU/mL(P=.001) at 48 weeks. After 48 weeks treatment, ALT significantly decreased from a mean ALT of 88.7 U/L before treatment to 37.5U/L (P=.04). After 48 weeks, the HBV DNA was undetectable in 14 (58.4%) in treatment-naïve patients and in 6 (31.6%) treatment-refractory patients. At 48 weeks 17 (60.7%) of HBeAg-negative patients and 3 (20%) HBeAg-positive patients achieved undetectable HBV DNA (P=.003). When the treatment was extended for a median of 24 months (range 12 months to 60 months), 29 (67.4%) achieved undetectable HBV DNA. Among 29 patients who achieved undetectable HBV DNA, the treatment refractory patients reached undetectability within a mean of 32.4 (18.6) months and treatment-naïve patients in a mean of 18.8 (10.5) months(P=.01). Two (13.3%) of HBeAg-reactive patients converted to HBeAg-negative status and one patient (2.3%)lost HBsAg. CONCLUSION: After treatment with entecavir, HBV DNA undetectable at 48 weeks in 58.4% of naïve patients.The response rate was better in HBeAg-negative and treatment-naïve patients compared to HBeAg-positive and treatment-refractory patients.

AIM: To determine liver transplantation outcomes in Wilson's disease (WD) patients, focusing on neurological manifestations. METHODS: This retrospective study assessed data from 16 WD patients (nine males, 56%) who had liver transplants between 1991 and 2007. Survival, graft function, and neurological complications were assessed during a follow-up period of up to 15 years. In addition, each patient's medical record was reviewed in detail to find the type of Wilson's disease (hepatic or hepatic plus neurological WD), indication for liver transplantation, use of chelating agents prior to transplantation, immediate and long term complications following transplantation, the donor details, and the pathology of explanted liver. RESULTS: End-stage liver disease was the indication for transplantation in all 16 WD patients. Four patients displayed WD-related neurological symptoms in addition to liver disease. Living-related liver transplantation was done in three cases. One patient died on postoperative day 6 due to primary graft non-function. One-year post liver transplant survival was 94%. Neurological manifestations of all four patients disappeared during their follow-up. Four patients developed acute cellular rejection, but all responded to treatment. One patient developed chronic ductopenic rejection after 15 years post-transplantation and their graft failed; this patient is currently waiting for re-transplantation. Fourteen patients (88%) are still living. The long-term average survival is currently 10.5 years, with a current median survival of 8 years. Long-term graft survival is currently 81%. CONCLUSION: Short- and long-term survival in WD patient liver transplantation was excellent, and neurological and psychological WD manifestations disappeared during long-term follow-up.
RESUMO
BACKGROUND AND OBJECTIVES: Wilson disease (WD) is a rare autosomal recessive disease. Our objective was to describe the diverse patterns, therapies, and outcomes of this disease. DESIGN AND SETTING: A retrospective study over two decades on WD patients in a tertiary care center in Saudi Arabia. PATIENTS AND METHODS: Clinical and laboratory findings of 71 patients with WD were retrieved from their charts, referral notes and our hospital electronic records and were analyzed. RESULTS: The 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. CONCLUSIONS: This 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.
