Innovative prophylactic and therapeutic approaches in liver cirrhosis.

Liver cirrhosis is the consequence of chronicisation and of the evolution of untreated liver diseases. The complexity of the disease and the complications it can cause have been and are still intensively researched, aiming to discover new therapies or improve existing ones for the effective management of liver cirrhosis. Currently, the treatment used is directed against the cause that caused the disease, if it is known; in advanced cases, liver transplantation is the only valid therapeutic option. Hepatoprotectors that are currently on the market are numerous, having as common properties the antioxidant, anti-inflammatory, stabilizing properties of the hepatocytic membrane; A few examples: the ethanolic extract of Curcuma longa, the extract from the plant called Sophora flavescens, the extract of Glycyrrhiza glabra, silymarin (extracted from Sylibum marianum), the extract of Ganoderma lucidum, etc. Liver cirrhosis is accompanied by generalized hypovitaminosis, so supplementing the diet with hydro- and liposoluble vitamins is mandatory. Protein-caloric malnutrition can be prevented by a hyperprotein diet, especially beneficial being the supplementation with branched-chain amino acids, which are also applicable in the prophylaxis and treatment of hepatic encephalopathy. Nanoparticles are a state-of-the-art therapeutic option, proving increased bioavailability, for example polydopamine nanoparticles loaded with l-arginine have been tested as therapy in liver cirrhosis. Among the innovative treatment directions in liver cirrhosis are hybrid products (e.g. hybrid polymer nanoparticles loaded with caffeic acid), cell cultures and artificial or bioartificial liver support.

Liver Injury and Elevated FIB-4 Define a High-Risk Group in Patients with COVID-19.

Liver involvement in Coronavirus Disease 2019 (COVID-19) has been widely documented. However, data regarding liver-related prognosis are scarce and heterogeneous. The current study aims to evaluate the role of abnormal liver tests and incidental elevations of non-invasive fibrosis estimators on the prognosis of hospitalized COVID-19 patients. We conducted a retrospective cohort study to investigate the impact of elevated liver tests, non-invasive fibrosis estimators (the Fibrosis-4 (FIB-4), Forns, APRI scores, and aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio), and the presence of computed tomography (CT)-documented liver steatosis on mortality in patients with moderate and severe COVID-19, with no prior liver disease history. A total of 370 consecutive patients were included, of which 289 patients (72.9%) had abnormal liver biochemistry on admission. Non-survivors had significantly higher FIB-4, Forns, APRI scores, and a higher AST/ALT ratio. On multivariate analysis, severe FIB-4 (exceeding 3.25) and elevated AST were independently associated with mortality. Severe FIB-4 had an area under the receiver operating characteristic (AUROC) of 0.73 for predicting survival. The presence of steatosis was not associated with a worse outcome. Patients with abnormal liver biochemistry on arrival might be susceptible to a worse disease outcome. An FIB-4 score above the threshold of 3.25, suggestive of the presence of fibrosis, is associated with higher mortality in hospitalized COVID-19 patients.

The ankle-brachial index-a classification of the patient education websites.

The authors present a classification of the most important types of online resources regarding the ankle-brachial index, for patients with peripheral arterial disease and other interested people (websites of national institutes, universities of medicine, regional hospitals, medical societies and associations etc).

A rare case of systemic autoimmune disease with intricate features of systemic sclerosis, lupus, polymyositis and rheumatoid arthritis. Overlap syndrome or mixed connective tissue disease?

We report an unusual case of connective tissue disease characterized by the coexistence of signs, symptoms and immunological features of 4 defined autoimmune diseases: systemic lupus erythematosus (SLE), systemic sclerosis (SSc), polymyositis (PM) and rheumatoid arthritis (RA). A 53-year-old female was admitted in our clinic with massive polyserositis (pretamponade) as well as skin, joint, muscular lesions and altered general status. The problem we found was the difficulty of including this case in a known clinical entity; SSc/SLE/PM//RA overlap syndrome and mixed connective tissue disease were the two most plausible diagnoses. We discuss the particularities of these clinical and immunological associations and the appropriate therapeutic options used in this kind of patients.
