Pharmacotherapy of Hepatic Encephalopathy
Hepatic encephalopathy (HE) or portosystemic encephalopathy (PSE) is a serious neuropsychiatric disorder resulting from liver failure. It is one of the common complications of liver cirrhosis and portosystemic shunting (PSS). Ammonia accumulation is one of the well-established causes. Ammonia is a by-product of the intestinal bacteria as a result of the breakdown of dietary supplements. In the normal state of the liver, the peripheral hepatocyte contains glutaminase that converts glutamine into glutamate and ammonia; ammonia will be detoxified and converted into urea. The variant manifestations were linked to the severity of HE. A wide range of neurological and psychiatric signs have been reported. The International Society for Hepatic Encephalopathy and Nitrogen Metabolism (ISHEN) uses asterixis (i.e., flapping tremor) as the first clinical sign of HE. Four factors should be taken into consideration to classify and distinguish HE from other conditions: HE type, severity of manifestations following West-Haven Criteria (WHC), HE time course, and presence of precipitating factors. Nonabsorbable disaccharides (lactulose and lactitol) and rifaximin have been the standard of care as first- and second-line therapies, respectively. Non-pharmacological interventions had a crucial role in HE management. Liver transplantation is the ultimate management of hepatic cirrhosis
Efficacy of generic sofosbuvir with daclatasvir compared to sofosbuvir/ledipasvir in genotype 4 hepatitis C virus: A prospective comparison with historical control
Abstract Background and Aim Management of genotype 4 hepatitis C virus (HCV) has shifted to interferonâfree regimens with a high sustained virological response (SVRâ12), especially with NS5B/NS5A inhibitor combinations such as sofosbuvir and ledipasvir (SofâLed). The guidelines have recommended the combination of sofosbuvir and another NS5A inhibitor, daclatasvir, to manage HCV genotypes 1â3. However, its use was extended to genotype 4 HCV based on extrapolating evidence. Our aim is to assess the efficacy of generic sofosbuvir + branded daclatasvir (SofâDac) compared to the SofâLed combination in treating genotype 4 HCV. Methods This study is an openâlabel, 2âperiod, noninferiority study that compared patients receiving a combination of generic sofosbuvir 400âmg and daclatasvir 60âmg orally daily (Group 2) prospectively to a historical control (Group 1) that included patients who received a combination of sofosbuvir/ledipasvir 400/90âmg orally daily. The primary endpoint is the proportion of patients who achieved SVRâ12. Results The study included 111 patients in the (SofâLed) Group 1 and 109 patients (SofâDac) Group 2. For the primary outcome, SVRâ12 was achieved in 106 (95.5%) of the patients in Group 1 versus 108 (99.1%) in Group 2 (pâ=â0.2). In addition, all patients who achieved SVRâ12 also achieved SVRâ24. Conclusion Generic sofosbuvir combined with branded daclatasvir was safe and effective for treating genotype 4 HCV compared to SofâLed. This combination may significantly reduce the cost burden, enabling a larger pool of treated patients. Office of research affairs at KFSHRC RAC# 2171 036
Mpox Perceptions and Vaccine Advocacy among the Healthcare Workers of Solid Organ Transplant Centers: A Multicenter, Cross-Sectional Survey in Saudi Arabia
Background: In response to the global Mpox outbreaks, this survey aimed to assess the knowledge, perceptions, and advocacy of Mpox vaccines among solid organ transplant healthcare workers (HCWs) in Saudi Arabia. Methods: A cross-sectional survey was conducted among solid organ transplant HCWs in Saudi Arabia from 15 August to 5 September 2022. A total of 199 responses were received from participants primarily working in the kidney (54.8%) and liver (14.6%) transplant units. Results: The survey found that most participants were aware of the 2022 Mpox outbreak, but the majority were more concerned about COVID-19 than Mpox. While the majority of participants thought laboratory personnel and HCWs in direct contact with Mpox patients should receive the vaccine, less than 60% believed that all HCWs should be vaccinated. Additionally, over half of the participants lacked knowledge of animalâhuman transmission of the virus. Conclusion: The results highlight the need for increased education on Mpox among transplant HCWs in Saudi Arabia, particularly regarding the virusâs transmission dynamics and vaccines. This education is crucial to improve HCWsâ understanding of this emerging disease, especially given their vulnerability during the COVID-19 pandemic
