Muscular fatigue may result from HIV infection, and may be associated with antiretroviral drug treatment. Clinical features linked to muscle biopsy findings may assist in determining etiology, and guide treatment decisions. This case series examined HIV patients in an ambulatory HIV clinic who received antiretroviral therapy, and complained of unexplained muscular fatigue. Clinical features with measurement of acid-base status, levels of lactate, aminotransferases, triglycerides and creatine kinase were correlated to light and electron microscopic results of muscle biopsy. Three patients with acquired mitochondrial changes on biopsy shared common features of lactatemia, elevated aminotransferases and triglycerides, and ultrasonographic hepatic steatosis. A fourth patient with normal mitochondria had myositis with fibrosis, but no systemic symptoms. Biochemical parameters were unremarkable, except for a high creatine kinase. Acquired mitochondrial disease may manifest as systemic illness and muscular fatigue. Unique metabolic changes and other organ dysfunction may precede overt physical signs of HIV myopathy.

Statins play an important role in the care of patients with cardiovascular disease and have a good safety record in clinical practice. The risk of hepatic injury caused by statins is estimated to be about 1 percent, similar to that of patients taking a placebo. Patients with transaminase levels no more than three times the upper limit of normal can continue taking statins; often the elevations will resolve spontaneously. Coexisting elevations of transaminase levels from nonalcoholic fatty liver disease and stable hepatitis B and C viral infections are not contra- indications to statin use. Although myalgias are common with statin use, myositis and rhabdomyolysis are rare. When prescribed at one-half the recommended maximal dosage or less, statins are associated with an incidence of myopathy similar to that of placebo; therefore, rou- tine monitoring of creatine kinase levels in asymptomatic patients is not recommended. Myopathic symptoms usually resolve approximately two months after discontinuing the statin, and the same statin can be restarted at a lower dosage, or patients can try a different statin. Clinically important drugs that interact with statins and increase the risk of adverse effects include fibrates, diltiazem, verapamil, and amiodarone.

A 49-year-old lady with no past medical history presented with dysphagia and 40-pound weight loss, which occurred over eight months. On physical examination, she had proximal muscle weakness and crackles in basilar regions of the lungs. Labs were significant for low albumin, elevated transaminases, and high aldolase. Imaging suggested aspiration pneumonitis in both lungs and hepatic steatosis. A swallow evaluation revealed oropharyngeal dysphagia and muscle biopsy confirmed a rare form of myositis. A liver biopsy showed steatohepatitis and a diagnosis of starvation-induced steatohepatitis was made. The patient succumbed to hypoxic respiratory failure from aspiration pneumonitis before the treatment for myositis could be initiated. We report the first case of starvation-induced steatohepatitis in a patient with dysphagia from myositis affecting the oropharyngeal musculature.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the least deadly but most infectious coronavirus strain transmitted from wild animals. It may affect many organ systems. Aim of the current guideline is to delineate the effects of SARS-CoV-2 on the liver. Asymptomatic aminotransferase elevations are common in coronavirus disease 2019 (COVID-19) disease. Its pathogenesis may be multifactorial. It may involve primary liver injury and indirect effects such as "bystander hepatitis," myositis, toxic liver injury, hypoxia, and preexisting liver disease. Higher aminotransferase elevations, lower albumin, and platelets have been reported in severe compared with mild COVID-19. Despite the dominance of respiratory disease, acute on chronic liver disease/acute hepatic decompensation have been reported in patients with COVID-19 and preexisting liver disease, in particular cirrhosis. Metabolic dysfunction-associated fatty liver disease (MAFLD) has a higher risk of respiratory disease progression than those without MAFLD. Alcohol-associated liver disease may be severely affected by COVID-19-such patients frequently have comorbidities including metabolic syndrome and smoking-induced chronic lung disease. World Gastroenterology Organization (WGO) recommends that interventional procedures such as endoscopy and endoscopic retrograde cholangiopancreatography should be performed in emergency cases or when they are considered strictly necessary such as high risk varices or cholangitis. Hepatocellular cancer surveillance may be postponed by 2 to 3 months. A short delay in treatment initiation and non-surgical approaches should be considered. Liver transplantation should be restricted to patients with high MELD scores, acute liver failure and hepatocellular cancer within Milan criteria. Donors and recipients should be tested for SARS-CoV-2 and if found positive donors should be excluded and liver transplantation postponed until recovery from infection.
