Impact of spider nevus and subcutaneous collateral vessel of chest/abdominal wall on outcomes of liver cirrhosis

Bloody Lips - Gluing Bleeding Lower Lip Spider Angioma in Decompensated Cirrhosis

Spider angiomas are dilated vascular channels in the skin. They have a central arteriole with surrounding vascular channels resembling legs of a spider, hence the name. They are frequently associated with liver cirrhosis, thyrotoxicosis, and pregnancy. We present the case of a 49-year-old gentleman who was referred to our liver clinic with complaints of jaundice and ascites of one-month duration. The patient was a chronic alcohol consumer, consuming country-made liquor, 80-100 grams/day for past 8-10 years. He was diagnosed with Acute on chronic liver failure with a model for end-stage liver disease score of 38. During his hospital stay, he developed active spurting from a spider angioma on his lower lip (video 1), which was initially tackled with hand compressions, which stopped bleeding for a few minutes, restarting again after the compressions were lifted. It was then decided to inject 0.1 mL cyanoacrylate glue injection using a 21-gauge needle, immediately stopping active spurt (video 2), (Figure 1). A small ulcer formed at the injection site, which healed in few days, and the patient was discharged to home. Spider angiomas are characteristic cutaneous manifestation of liver cirrhosis with a specificity of 95%.1 The prevalence of spider angiomas in cirrhosis is reported to be around 30-40%. Li Hongyu et al. in their study on 198 individuals reported the prevalence to be 47%.2 They can be graded from grade 1+ (readily recognizable containing a body, legs, and surrounding erythema) to grade 4+ (visible pulsations with a hand lens and raised central punctum with many obvious "spider legs" radiating from it).3 Underlying pathogenesis in cirrhosis is multifactorial including decrease levels of testosterone and high levels of estradiol,4 hyperdynamic circulation, high levels of substance-P, and vascular endothelial growth factor leading to angiogenesis and vasodilation.5,6 Spider angiomas can be single or multiple and are usually seen in the territory of superior vena cava-the face (nose, lips, forehead), upper chest, and arms.2 These lesions have been associated with bleeding esophageal varices and hepatopulmonary syndrome. Bleeding from spider angiomas is unusual. Rarely, fine-needle electrocautery, potassium-titanyl-phosphate (KTP) laser, or electro desiccation has been used to clear spider angiomas for cosmetic concerns. Treatment includes hand or ice compressions and treating the underlying cause. Use of cyanoacrylate glue for bleeding spider angioma has not been reported in the literature. We think this can be a handy bedside tool to combat an active spurt of bleeding when conventional methods have failed, as in our case; however, further studies are warranted.

Spontaneous portosystemic shunts outside the esophago-gastric region: Prevalence, clinical characteristics, and impact on mortality in cirrhotic patients: A systematic review and meta-analysis

BACKGROUND

Spontaneous portosystemic shunt (SPSS) other than esophago-gastric varices is one of the consequences of cirrhosis-induced portal hypertension (PHT), but its role is not fully understood. Therefore, we conducted a systematic review and meta-analysis to determine the prevalence and clinical characteristics of SPSS (excluding esophago-gastric varices) and its impact on mortality in patients with cirrhosis.

METHODS

Eligible studies were identified from MedLine, PubMed, Embase, Web of Science, and Cochrane Library between Jan 1, 1980 and Sep 30, 2022. Outcome indicators were SPSS prevalence, liver function, decompensated events, and overall survival (OS).

RESULTS

Totally, 2015 studies were reviewed, of which 19 studies recruiting 6884 patients were included. On pooled analysis, the prevalence of SPSS was 34.2% (26.6%∼42.1%). SPSS patients had significantly higher Child-Pugh scores and grades and Model for End-stage Liver Disease scores (all P<0.05). Moreover, SPSS patients experienced a higher incidence of decompensated events, including hepatic encephalopathy, portal vein thrombosis, and hepatorenal syndrome (all P<0.05). Additionally, SPSS patients had significantly shorter OS than the non-SPSS group (P<0.05).

CONCLUSIONS

In patients with cirrhosis, SPSS outside the esophago-gastric region is common, characterized by severe impairment of liver function, high rates of decompensated events, including HE, PVT, and hepatorenal syndrome, as well as a high mortality rate.

Spider Angioma Number and Location as Potential Prognostic Indicators in Chronic Liver Disease: A Case Report

Spider angiomas (SAs) are a well-known physical exam feature found in patients with chronic liver disease. While SAs are thought to correspond with a higher risk of mortality in chronic liver disease (CLD) patients, only few studies have been done to assess the number and location of SAs as prognostic indicators. We present a case of a 64-year-old patient with decompensated CLD who was found to have three SAs on physical exam. The patient presented to the inpatient service at a community hospital in Miami, Florida. He had experienced previous esophageal varices banding, had a Model for End-Stage Liver Disease (MELD) score of 31, and needed large-volume paracentesis due to significant ascites. It was determined that he had a very poor prognosis and was in need of a liver transplant. We suggest that more research is necessary to determine if there is a prognostic importance to the number and location of SAs in patients with CLD, as earlier interventions could potentially lead to improvements in outcomes through this physical exam finding.

Non-invasive diagnosis and follow-up of portal hypertension

Compensated advanced chronic liver disease (cACLD) describes the spectrum of advanced fibrosis/cirrhosis in asymptomatic patients at risk of developing clinically significant portal hypertension (CSPH, defined by a hepatic venous pressure gradient (HVPG) ≥10 mmHg). Patients with cACLD are at high risk of liver-related morbidity and mortality. In patients at risk of chronic liver disease, cACLD is strongly suggested by a liver stiffness (LSM) value >15 kPa or clinical/biological/radiological signs of portal hypertension, and ruled out by LSM <10 kPa, or Fibrotest® ≤0.58, or Fibrometer® ≤0.786. Patients with chronic liver disease (excluding vascular diseases) with a LSM <10 kPa are at low risk of developing portal hypertension complications. The presence of CSPH can be strongly suspected when LSM is ≥20 kPa. In a patient without clinical, endoscopic or radiological features of portal hypertension, measurement of the HVPG is recommended before major liver or intra-abdominal surgery, before extra-hepatic transplantation and in patients with unexplained ascites. Endoscopic screening for oesophageal varices can be avoided in patients with LSM <20 kPa and a platelet count >150 G/L (favourable Baveno VI criteria) at the time of diagnosis. There is no non-invasive method alternative for oeso-gastroduodenal endoscopy in patients with unfavourable Baveno criteria (liver stiffness ≥20 kPa or platelet count ≤50 G/l). Platelet count and liver stiffness measurements must be performed once a year in patients with cACLD with favourable Baveno VI criteria at the time of diagnosis. A screening oeso-gastroduodenal endoscopy is recommended if Baveno VI criteria become unfavourable.

The relationship between spider naevi & de novo arteriovenous malformations in chronic liver disease

We report a patient with decompensated alcoholic liver cirrhosis (Child-Turcotte-Pugh class C) who developed a de novo left frontal cerebral AVM and a subcutaneous left temporal scalp spider naevus. Arteriovenous malformations (AVMs) are vascular abnormalities previously thought to be congenital in nature, although new research has revealed the potential for de novo AVM formation through a two-hit hypothesis. We propose that the oestrogen-rich environment seen in chronic liver disease could act as the second hit to allow for an angiogenic state favouring de novo AVM development. We also postulate that spider naevi are formed through a similar mechanism and may represent early-stage AVMs.

Computed Tomography Images of Spontaneous Portosystemic Shunt in Liver Cirrhosis

Spontaneous portosystemic shunt (SPSS) refers to collateral vessels that communicate between the portal vein system and systemic circulation. SPSS mainly includes esophageal varices, gastric varices, left gastric vein, recanalized paraumbilical vein, abdominal wall varices, and spontaneous splenorenal shunt. SPSS contributes to the development of hepatic encephalopathy caused by portal vein inflow bypassing and carries a higher risk of death in liver cirrhosis. Abdominal contrast-enhanced computed tomography is a major imaging approach to establish a diagnosis of SPSS and evaluate its location and feature. This review primarily describes the main contrast-enhanced CT features of SPSS in liver cirrhosis.

Computational analysis for identification of early diagnostic biomarkers and prognostic biomarkers of liver cancer based on GEO and TCGA databases and studies on pathways and biological functions affecting the survival time of liver cancer

BACKGROUND

Liver cancer is the sixth most commonly diagnosed cancer and the fourth most common cause of cancer death. The purpose of this work is to find new diagnostic biomarkers or prognostic biomarkers and explore the biological functions related to the prognosis of liver cancer.

METHODS

GSE25097 datasets were firstly obtained and compared with TCGA LICA datasets and an analysis of the overlapping differentially expressed genes (DEGs) was conducted. Cytoscape was used to screen out the Hub Genes among the DEGs. ROC curve analysis was used to screen the Hub Genes to determine the genes that could be used as diagnostic biomarkers. Kaplan-Meier analysis and Cox proportional hazards model screened genes associated with prognosis biomarkers, and further Gene Set Enrichment Analysis was performed on the prognosis genes to explore the mechanism affecting the survival and prognosis of liver cancer patients.

RESULTS

790 DEGs and 2162 DEGs were obtained respectively from the GSE25097 and TCGA LIHC data sets, and 102 Common DEGs were identified by overlapping the two DEGs. Further screening identified 22 Hub Genes from 102 Common DEGs. ROC and survival curves were used to analyze these 22 Hub Genes and it was found that there were 16 genes with a value of AUC > 90%. Among these, the expression levels of ESR1,SPP1 and FOSB genes were closely related to the survival time of liver cancer patients. Three common pathways of ESR1, FOBS and SPP1 genes were identified along with seven common pathways of ESR1 and SPP1 genes and four common pathways of ESR1 and FOSB genes.

CONCLUSIONS

SPP1, AURKA, NUSAP1, TOP2A, UBE2C, AFP, GMNN, PTTG1, RRM2, SPARCL1, CXCL12, FOS, DCN, SOCS3, FOSB and PCK1 can be used as diagnostic biomarkers for liver cancer, among which FOBS and SPP1 genes can also be used as prognostic biomarkers. Activation of the cell cycle-related pathway, pancreas beta cells pathway, and the estrogen signaling pathway, while on the other hand inhibition of the hallmark heme metabolism pathway, hallmark coagulation pathway, and the fat metabolism pathway may promote prognosis in liver cancer patients.

A microneedling device for the treatment of spider vein: A case report

Spider vein is mostly seen in patients with liver disease, although the underlying problem is sometimes unknown. If spider vein appears on the face, it can affect the self-esteem and self-image of patients. Particularly, females are more vulnerable to these complications. Spider nevi are mostly left untreated since they are considered a cosmetic matter; in case of treatment, the procedure is costly with limited satisfaction. Therefore, this study reports the successful treatment of a spider vein case using a microneedling procedure.
