Type C hepatic encephalopathy (HE) is a brain dysfunction caused by severe hepatocellular failure or presence of portal-systemic shunts in patients with liver cirrhosis. In its subclinical form, called “minimal hepatic encephalopathy (MHE), only psychometric tests or electrophysiological evaluation can reveal alterations in attention, working memory, psychomotor speed and visuospatial ability, while clinical neurological signs are lacking. The term “covert” (CHE) has been recently used to unify MHE and Grade I HE in order to refer to a condition that is not unapparent but also non overt. “Overt” HE (OHE) is characterized by personality changes, progressive disorientation in time and space, acute confusional state, stupor and coma. Based on its time course, OHE can be divided in Episodic, Recurrent or Persistent. Episodic HE is generally triggered by one or more precipitant factors that should be found and treated. Unlike MHE, clinical examination and clinical decision are crucial for OHE diagnosis and West Haven criteria are widely used to assess the severity of neurological dysfunction. Primary prophylaxis of OHE is indicated only in the patient with gastrointestinal bleeding using non-absorbable antibiotics (Rifaximin) or non-absorbable disaccharides (Lactulose). Treatment of OHE is based on the identification and correction of precipitating factors and starting empirical ammonia-lowering treatment with Rifaximin and Lactulose (per os and enemas). The latter should be used for secondary prophylaxis, adding Rifaximin if HE becomes recurrent. In recurrent/persistent HE, the treatment options include fecal transplantation, TIPS revision and closure of eventual splenorenal shunts. Treatment of MHE should be individualized on a case-by-case basis.

Clinical history of liver cirrhosis is characterised by two phases: the asymptomatic phase, also termed ‘compensated cirrhosis’, and the phase of complications due to the development of portal hypertension and liver dysfunction, also termed ‘decompensated cirrhosis’, in which patients may develop ascites, the most frequent and clinically relevant complication of liver cirrhosis. Ascites can be classified into uncomplicated and complicated according to the development of refractoriness, spontaneous bacterial peritonitis (SBP) or the association with hepatorenal syndrome (HRS). In this narrative review, we will extensively discuss the optimal pharmacological and non-pharmacological management of cirrhotic ascites with the aim to offer an updated practical guide to Internal Medicine physicians. According to the amount of fluid in the abdominal cavity, uncomplicated ascites is graded from 1 to 3, and the cornerstone of its management consists of restriction of salt intake, diuretics and large-volume paracentesis (LVP); in recent years, long-term administration of human albumin has acquired a new interesting role. Refractory ascites is primarily managed with LVP and transjugular intrahepatic portosystemic shunt (TIPS) placement in selected patients. The occurrence of renal impairment, especially HRS, worsens the prognosis of patients with cirrhotic ascites and deserves a specific treatment. Also, the management of SBP faces the rising and alarming spread of antibiotic resistance. Hepatic hydrothorax may even complicate the course of the disease and its management is a challenge. Last but not least, liver transplantation (LT) is the ultimate and more effective measure to offer to patients with cirrhotic ascites, particularly when complications occur.

Hemorrhoids are one of the most common diseases of the anorectal region. Previously, treatment for hemorrhoids included conservative treatment, outpatient treatment, and surgical treatment. The development of flexible reversible endoscopes has provided precise controllability and imaging, enabling further improvement and development of various endoscopic techniques to treat hemorrhoids. This article discusses several of these endoscopic techniques: rubber band ligation, sclerotherapy, and electrocoagulation. The development, efficacy, and advantages of these treatments are summarized and evaluated. It is expected that going forward, endoscopic technology will be further applied in clinical practice and may become the first-line method for the treatment of hemorrhoids.

Shengxuening (SXN), as an effective supplement to heme-like iron, has been widely used in China to treat renal anemia. However, proof of its use for improving inflammation is scarce in the past decades. This work aimed to evaluate the effectiveness of SXN with inflammatory factors as primary endpoints. By searching PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), China Biology Medicine disc (CBM), VIP Information/ China Science and Technology Journal Database, and WANFANG Database, we identified previous studies that met the inclusion criteria and included them in the systematic review. Analyses were performed using STATA. Nine randomized controlled trials were included in this systematic review. The results revealed that, when compared with oral iron supplementation, SXN can reduce the level of inflammatory factors, including hs-CRP (WMD -1.93 mg/L; 95% CI -2.14 to -1.72), IL-6 ( P < 0.05), and TNF-α ( P < 0.05), and significantly enhance the level of Hb (WMD 13.40 g/L; 95% CI 12.95 to 13.84), TSAT (WMD 6.88%; 95% CI 6.50 to 7.26), and SF (WMD 38.46 μg/L; 95% CI 23.26 to 53.67). Moreover, SXN exhibits a superior security than oral iron supplementation with less gastrointestinal adverse reactions (RR 0.14; 95% CI 0.06 to 0.32). In patients with renal anemia, SXN is more efective and safer than oral iron supplementation, especially in reducing the level of inflammation.

Background and Objectives SARS-CoV-2-induced ARDS is a new entity that should be characterized as it appears to be different from standard ARDS. Hypernatremia is a biological alteration that seems to occur very often in this population without any clear cause. The present study aims to clarify the possible causes of hypernatremia and evaluate its impact on patient outcome. Patients and Methods We conducted a retrospective one-day prevalence study in 2 intensive care units, which only treated COVID-19 patients with moderate to severe ARDS. We measured blood and urine electrolytes in all the patients. Patients with chronic renal failure or renal replacement therapy were excluded from the study. Hypernatremia was defined as plasma sodium levels above 145 mmol/L. Results Inclusion criteria were met in 17 out of 24 patients. Hypernatremia was present in 52% patients. All had a natriuresis higher than 20 mmol/L and a urine osmolality above 600 mOsm/L. Hypernatremia was acquired in ICU as all the patients had a normal serum sodium level at admission. Conclusion The incidence of hypernatremia was elevated and appears to be linked to significant insensible water losses. This should trigger us to optimize the maintenance fluid therapy in critically ill patients with SARS-CoV-2-induced ARDS.

Background and Objective While highly effective hepatitis C virus (HCV) therapies exist, gaps in the cascade of care remain. Disparities in the HCV cascade are prominent among underserved safety-net populations. We aim to evaluate the HCV cascade among an urban safety-net cohort of HCV patients. Methods We retrospectively evaluated adults with chronic HCV to determine rates of linkage to care (LTC), retention to care, and receiving HCV treatment from 2002 to 2018. Comparisons between groups utilized Chi-square testing; comparisons of median time to LTC and HCV treatment were evaluated with Student’s t -test and analysis of variance. Results Among 600 chronic HCV patients (60.7% male, 20.7% non-Hispanic white, 49.2% African American, 92.5% treatment naïve, 26.8% cirrhosis), successful LTC within one year of HCV diagnosis was 57.7%, among which, 91.6% were successfully retained into care. In those with successful LTC, 72.6% received HCV treatment, 91.8% completed treatment, and 89% achieved SVR12. Women with HCV experienced longer delays from LTC to HCV treatment (331 vs . 206 days in men, P < 0.05), as did African Americans (280 vs . 165 days in non-Hispanic whites, P < 0.05). Compared to the non-Hispanic whites, HCV treatment was lower in African Americans (70.4% vs . 74.4%, P < 0.05). Conclusion Women with HCV experienced significant delays along the HCV cascade, with median time of over 2 years from diagnosis to treatment. African Americans also experienced significant delays along the HCV cascade of care. However, sex and race/ethnicity were not found to be significant predictors of overall LTC or treatment.

Background and Objective Thrombophilia is a term used to define the conditions creating a tendency toward thrombosis. Factor V Leiden (FVL) is the most frequently observed genetic risk factor, and its frequency varies among societies and ethnicities. In this study, our aim is to identify the frequency of FVL mutation in patients with thrombosis, the frequency of FVL mutation for each thrombosis disease, whether there is any difference in the geographical distribution of FVL mutation in the Turkish population, correlation with age and gender, and correlation with arterial and venous thrombosis. Methods This is an observational case–control and retrospective study. Cases with the FVL mutation examination with clinical provisional diagnosis of arterial and/or venous thrombosis delivered and with the thrombosis proven by radiological visualization methods and laboratory examinations have been planned to be considered and assessed as cases with thrombosis. Results A total of 67 patients with thrombosis and 22 patients without thrombosis have been included within the study. Twenty-six of the cases with thrombosis were from the Black Sea region, 21 were from Eastern Anatolia, 12 were from Central Anatolia, 5 were from Marmara, and 3 were from Southeastern Anatolia. Eleven of the cases without thrombosis were from the Black Sea region, 1 was from Eastern Anatolia, 5 were from Central Anatolia, 2 were from Marmara, 1 was from Southeastern Anatolia, and 2 were from the Aegean region. The significance was resulted from the identification of thrombosis prevalence rate as significantly high in the Eastern Anatolian region. Discussion FVL mutation frequency is quite common in our country, and there are significant differences particularly in terms of regional distribution. Furthermore, FVL mutation is solely not the risk factor for thrombosis, and other coexisting genetic and acquired risk factors are substantial causes for the development of thrombosis.
