Thrombocytopenia is one of the most frequent implications of liver cirrhosis. This condition, when present in the severe form [platelet count (PLT) less than 50 × 10⁹/L] correlates, with an increased risk of bleeding during the main diagnostic-therapeutic procedures which cirrhotic patients usually undergone. In these cases, generally, an infusion of platelets is performed, albeit in recent years has been replaced by a cycle of second generation thrombopoietin receptor (TpoR) agonists. This article reports two different cases concerning respectively an 83-year-old female patient suffering from arterial hypertension, aneurysm of the sub-renal aorta, hepatitis C virus (HCV)-positive liver cirrhosis responsive to treatment with antiviral drugs, and a 2.0 cm diameter hepatocellular carcinoma (HCC) nodule localized in the hepatic segment III and a 53-year-old female patient with HCV-positive liver cirrhosis complicated by portal hypertension with splenomegaly, thrombocytopenia, and F3 esophageal varices at high risk of bleeding. Both of them, eligible for invasive procedures such as HCC transarterial chemoembolization (TACE) and for esophageal variceal band ligation, were prescribed prophylaxis with TpoR agonists due to their severe and persistent thrombocytopenia. These two cases show how a short course of lusutrombopag allows to safely perform one or more invasive procedures and how the administration of the drug can be repeated without losing efficacy. Furthermore, this drug shows an excellent safety profile and avoids the risks of platelet transfusion. In conclusion, second generation TpoR agonists can be considered the prophylactic treatment of choice to reduce the risk of bleeding in patients with liver cirrhosis and severe thrombocytopenia.

Flavonoids present a large group of natural polyphenols with numerous important health benefits for preventing and treating a diverse variety of pathological conditions. However, the actual therapeutic use of these phytochemicals is impeded by their low oral bioavailability. In this commentary article, an interesting paradox is presented: while the ingested flavonoid glycosides can be absorbed by means of sodium-dependent glucose transporters (SGLTs; SGLT1) located in the brush border membrane facing the lumen of the small intestine, certain flavonoid aglycones are able to inhibit these shuttle proteins. It is expected that avoiding the co-intake of such SGLT1 inhibitors concomitantly with flavonoid-rich foods might provide a new option for enhancing the oral bioavailability of flavonoids, thereby preventing the transport of unabsorbed compounds to the large intestine and conversion into catabolites by the colonic microbiota. Altogether, the administration of flavonoids in appropriate combinations is highlighted for getting the maximal health benefits from consuming these bioactive compounds.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), known to cause the coronavirus disease 2019 (COVID-19), was declared a pandemic in early 2020. During the past time, several infections control methods have been developed. Nevertheless, all of them have certain limitations: uncertainty in duration, limited efficacy of vaccines, and lack of effective drugs for COVID-19 treatment. So, the issue of creating drugs for symptomatic and etiotropic therapy is still relevant. This review summarizes the current knowledge of using natural compounds as anti-SARS-CoV-2 agents by analysing the results of in vitro studies and completed clinical trials (CTs). Also, this work highlighted the most active molecules and discussed the possibility of using some compounds in clinical practice.

Nonalcoholic fatty liver disease (NAFLD), its more rapidly progressive steatohepatitic variant [nonalcoholic steatohepatitis, (NASH)], and the recently defined metabolic dysfunction-associated fatty liver disease (MAFLD) may be collectively alluded to as “metabolic fatty liver syndromes” (MFLS). MFLS is a common clinical complaint for which no licensed drug treatment is available and a public health issue posing a heaven burden on healthcare systems. Iron plays a key role in many of the key pathogenic steps concurring in the development and progression of MFLS, notably including genetics, intestinal dysbiosis, adipositis, insulin resistance, metaflammation, oxidative stress and ferroptosis, endoplasmic reticulum stress, and hepatic fibrosis. This notion raises the logical expectation that iron depletion, which can easily be implemented with venesection, might improve several aspects of MFLS. However, few published studies have globally failed to support these expectations. In conclusion, venesection in MFLS exhibits a strong biological rationale and possible metabolic benefits. However, confronted with failures in hepato-histological outcomes, data call for additional studies aimed to reconcile these inconsistencies.

Despite recent advancements in the field of neuro-ophthalmology, the rising rates of neurological and ophthalmological conditions, mismatches between supply and demand of clinicians, and an aging population underscore the urgent need to explore new therapeutic approaches within the field. Glucagon-like peptide 1 receptor agonists (GLP-1RAs), traditionally used in the treatment of type 2 diabetes, are becoming increasingly appreciated for their diverse applications. Recently, GLP-1RAs have been approved for the treatment of obesity and recognized for their cardioprotective effects. Emerging evidence indicates some GLP-1RAs can cross the blood-brain barrier and may have neuroprotective effects. Therefore, this article aims to review the literature on the neurologic and neuro-ophthalmic role of glucagon-like peptide 1 (GLP-1). This article describes GLP-1 peptide characteristics and the mechanisms mediating its known role in increasing insulin, decreasing glucagon, delaying gastric emptying, and promoting satiety. This article identifies the sources and targets of GLP-1 in the brain and review the mechanisms which mediate its neuroprotective effects, as well as implications for Alzheimer’s disease (AD) and Parkinson’s disease (PD). Furthermore, the preclinical works which unravel the effects of GLP-1 in ocular dynamics and the preclinical literature regarding GLP-1RA use in the management of several neuro-ophthalmic conditions, including diabetic retinopathy (DR), glaucoma, and idiopathic intracranial hypertension (IIH) are discussed.
