Saudi association for the study of liver diseases and transplantation position statement on liver transplantation during the COVID-19 pandemic
The World Health Organization (WHO), on March 11th 2020, upgraded the status of the novel coronavirus disease (COVID-19) from epidemic to pandemic. Over two million individuals have been infected with SARS-CoV-2, the virus causing COVID-19, and as of April, 14th 2020, there were over 5000 confirmed cases in Saudi Arabia (SA). Many countries, including SA, have imposed major restrictions on travel, and everyday life, and the implications of these necessary changes are being felt in liver transplant (LT) centers in SA. Concerns remain that there is an increased risk for individuals over 65 years of age, with underlying medical conditions, or for those who are immunocompromised. Therefore, the Saudi Association for the Study of Liver Diseases and Transplantation (SASLT) established an urgent task force to launch a statement that can be utilized by LT centers as a guidance in the management of patients with advanced liver disease from the time of LT listing to the post-operative care of transplanted patients.
Cardiovascular changes in cirrhosis: Pathogenesis and clinical implications
Liver cirrhosis is associated with a wide range of cardiovascular abnormalities including hyperdynamic circulation, cirrhotic cardiomyopathy, and pulmonary vascular abnormalities. The pathogenic mechanisms of these cardiovascular changes are multifactorial and include neurohumoral and vascular dysregulations. Accumulating evidence suggests that cirrhosis-related cardiovascular abnormalities play a major role in the pathogenesis of multiple life-threatening complications including hepatorenal syndrome, ascites, spontaneous bacterial peritonitis, gastroesophageal varices, and hepatopulmonary syndrome. Treatment targeting the circulatory dysfunction in these patients may improve the short-term prognosis while awaiting liver transplantation. Careful fluid management in the immediate post-transplant period is extremely important to avoid cardiac-related complications. Liver transplantation results in correction of portal hypertension and reversal of all the pathophysiological mechanisms that lead to the cardiovascular abnormalities, resulting in restoration of a normal circulation. The following is a review of the pathogenesis and clinical implications of the cardiovascular changes in cirrhosis.
Management of hepatitis c genotype 4 in the liver transplant setting
End-stage liver disease secondary to hepatitis C virus (HCV) infection is the major indication for orthotopic liver transplantation (OLT) worldwide. The percentage of HCV patients infected with genotype 4 (G4) among recipients of OLT varies depending on geographic location. In the Middle East, including Saudi Arabia, G4 infection is the most common genotype among transplant recipients. Due to the low prevalence of HCV-G4 in Europe and the United States, this genotype has not been adequately studied in prospective trials evaluating treatment outcomes and remains the least studied variant. The aim of this review is to summarize the natural history and treatment outcome of HCV-G4 following liver transplantation, with particular attention to new HCV therapies. This review incorporates all published studies and abstracts including HCV-G4 patients.
Prevalence of biopsy-proven nonalcoholic fatty liver among patients with gallstone disease
Background/Aim: Gallstone disease (GD) and nonalcoholic fatty liver disease (NAFLD) are associated with metabolic syndrome. Despite the benign nature of NAFLD, 10% of patients may develop advanced fibrosis and cirrhosis. We aimed to identify the prevalence and factors associated with NAFLD among GD patients in the Saudi population. Patients and Methods: This is a single-center, observational cohort study that included patients seen in general surgery clinics at our institution from 2011 to 2017. All liver biopsies were taken at the same time as the cholecystectomy. Demographical and clinical data were prospectively collected from the study population. Results: Of the 301 GD patients in the study, 15% had a normal body mass index (BMI), 29% were overweight, and 56% were obese. There were 143 (47.8%) patients with NAFLD, of which 125 (41.8%) showed steatosis and 18 (6%) had nonalcoholic steatohepatitis. There was a significant positive correlation between NAFLD and age (r = 0.243; P < 0.0001), and BMI (r = 0.242; P < 0.0001). Obese patients with BMI 30-40 kg/m[2] were 2.403 (P = 0.039) more likely to have NAFLD compared with normal BMI patients, and this value increased to 6.145 (P = 0.002) in patients with BMI >40 kg/m[2]. Additionally, patients with T2DM were 2.839 times (P = 0.015) more likely to have NAFLD compared with those who did not. Conclusions: The prevalence of NAFLD among GD patients is high. High BMI and diabetes are independent factors associated with NAFLD in GD patients. The results suggest that there may be a need for routine liver biopsy in selected patients during cholecystectomy.
Hepatitis B management: It is time to change the strategy
[...]the development of potent HBV drugs with high genetic barriers to resistance has resulted in significant suppression of viral replication over a longer period of time. [...]overall patient survival has improved due to the prevention of disease progression to cirrhosis.
