Spider angiomas in patients with liver cirrhosis: role of alcoholism and impaired liver function

Recognizing skin conditions in patients with cirrhosis: a narrative review

Background: The skin is a major target organ for extrahepatic manifestations of liver diseases, and dermatologic abnormalities are common in patients with hepatic disorders. Clinical examination of the skin, nails and hair can allow for appropriate recognition, early diagnosis and treatment of liver diseases, and improvement in the quality of life and life expectancy of affected patients.Methods: We searched 3 databases (Pubmed,Medline and Embase) and selected studies about cirrhosis related skin manifestations and their pathophysiology.Results: A total of 73 articles were included in the review. Studies displayed the spectrum of cutaneous manifestations related to hormonal and vascular changes as well as nail and hair changes in patients with cirrhosis and/or portal hypertension.Conclusion: Cutaneous alterations are important clues or potential indications in the diagnosis of liver cirrhosis. Familiarity with skin conditions can be promptly diagnosed and appropriate management initiated.KEY MESSAGESManifestations of the liver and skin disorders are interrelated in various ways. Cutaneous changes may be the first clue that a patient has liver disease.The skin is a major target organ for extrahepatic manifestations of liver diseases. A broad range of cutaneous alterations can be present in patients with cirrhosis, such as vascular, nail, hair, hormonal changes, etc.Recognizing these signs is crucial so that potential underlying diseases including liver disease can be promptly diagnosed and appropriate management timely initiated.

The effects of alcohol and illicit drug use on the skin

Early identification of cutaneous manifestations of alcohol and illicit drug use can aid in the diagnosis and management of these uses, as well as their sequelae. In addition, the effects of alcohol and illicit drug use on the skin can result in significant morbidity. Alcohol misuse can present with jaundice, pruritus, pigmentary alterations, urticaria, hair and nail changes, and oral changes. It is also a risk factor for skin cancer and infections. Vascular disturbances associated with alcohol misuse include telangiectasias, palmar erythema, caput medusae, and flushing. Diseases related to alcohol misuse include nutritional deficiencies, porphyria cutanea tarda, psoriasis, seborrheic dermatitis, nummular dermatitis, and rosacea. Other conditions seen in alcohol misuse include Dupuytren contracture, Peyronie disease, and pancreatitis. Dermatologists should also be aware of hepatotoxic medications that are commonly prescribed for skin diseases so as to avoid initiating hepatoxicity in patients who use alcohol. Illicit drug use can manifest with cutaneous fibrosis, scarring, granulomas, ulceration, pruritus, infections, cocaine-levamisole-induced vasculitis, tooth decay, and oral disease. By recognizing the cutaneous stigmata of alcohol and illicit drug use, dermatologists can aid in the identification and treatment of patients suffering from these addictions.

Spider Angioma of the Nasal Mucosa

Spider angioma is a benign vascular lesion reminiscent of a spider's body characterized by peculiar dilatation of end vasculature. The lesion is characterized by a central spot and extensions which radiate outward like a spider's body. Spider angiomas may appear as a solitary or multiple lesion that arises on the skin surface of the face, neck, chest, and arms; these lesions have been rarely observed in the sublingual mucosa and in the gut, and to date, they have never been reported in the nasal mucosa. In this article, we report a spider angioma of the nasal cavity found as an occasional finding during a narrow band imaging nasopharyngeal endoscopy in a 70-year-old male patient with hepatitis C virus-related liver cirrhosis and a history of total laryngectomy in 2013 due to laryngeal squamous cell carcinoma. The lesion was located in the mucosa of the pavement of the posterior portion of the left nostril; it was painless and asymptomatic.

Cutaneous Manifestations of Chronic Liver Disease

Given the visibility of cutaneous findings, skin manifestations are often a presenting symptom of underlying systemic disease, including chronic liver disease. Many cutaneous signs and symptoms that correlate with chronic liver disease are common physical examination findings in patients with no history of liver disease. It is nonetheless important to be aware that these cutaneous findings may be an indication of underlying liver disease and often occur in the setting of such hepatic dysfunction. This article covers general cutaneous signs that may correlate with various liver diseases and describes specific cutaneous signs as they relate to more specific liver diseases.

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

INTRODUCTION

Spider nevus and subcutaneous collateral vessel of the chest/abdominal wall are common in liver cirrhosis. This prospective study aimed to evaluate the impact of spider nevus and subcutaneous collateral vessel of the chest/abdominal wall on the outcomes of cirrhotic patients.

MATERIAL AND METHODS

We prospectively enrolled patients with a diagnosis of liver cirrhosis consecutively admitted to our department. We recorded the number and location of spider nevi and subcutaneous collateral vessels of the chest/abdominal wall. Clinical profiles and survival were compared according to the presence of spider nevus and subcutaneous collateral vessel of the chest/abdominal wall. The study was registered (NCT02468479).

RESULTS

Overall, 198 patients were enrolled between June 2015 and May 2016. The median follow-up duration was 350 days. The prevalence of spider nevus and subcutaneous collateral vessel of the chest/abdominal wall was 47% and 29.8%, respectively. Patients with spider nevi had a significantly higher proportion of alcohol abuse (54.84% vs. 26.67%, p < 0.001). Both spider nevus and subcutaneous collateral vessel of the chest/abdominal wall were significantly associated with higher Child-Pugh (8.35 ±2.19 vs. 7.47 ±1.91, p = 0.005; 8.57 ±2.20 vs. 7.60 ±1.98, p = 0.002) and MELD scores (9.91 ±6.41 vs. 7.43 ±5.40, p = 0.008; 10.77 ±6.76 vs. 7.68 ±5.42, p = 0.003). The cumulative survival was not significantly different between patients with and without spider nevi of the chest/abdominal wall (p = 0.951). Patients with subcutaneous collateral vessels of the chest/abdominal wall had significantly worse cumulative survival (p = 0.018).

CONCLUSIONS

Presence of spider nevus and subcutaneous collateral vessel of the chest/abdominal wall indicated more severe liver dysfunction. Subcutaneous collateral vessel of the chest/abdominal wall should be a simple and important predictor for the overall survival of cirrhotic patients.

Identification and Analysis of Human Microbe-Disease Associations by Matrix Decomposition and Label Propagation

Studies have shown that microbes exist widely in the human body and are closely related to human complex diseases. Predicting potential associations between microbes and diseases is conducive to understanding the mechanisms of complex diseases and can also facilitate the diagnosis and prevention of human diseases. In this paper, we put forward the Matrix Decomposition and Label Propagation for Human Microbe-Disease Association prediction (MDLPHMDA) on the basis of the dataset of known microbe-disease associations collected from the database of HMDAD and the Gaussian interaction profile kernel similarity for diseases and microbes, disease symptom similarity. Moreover, the performance of our model was evaluated by means of leave-one-out cross validation and five-fold cross validation, and the corresponding AUCs of 0.9034 and 0.8954 ± 0.0030 were gained, respectively. In case studies, 10, 9, 9, and 8 out of the top 10 predicted microbes for asthma, colorectal carcinoma, liver cirrhosis, and type 1 diabetes were confirmed by literatures, respectively. Overall, evaluation results showed that MDLPHMDA has good performance in potential microbe-diseasepositive free parameter, which associations prediction.

Videodermoscopy and doppler-ultrasound in spider naevi: towards a new classification?

INTRODUCTION

Spider naevi (SN) are considered a subtype of telangiectasias, currently classified as low-flow vascular malformations.

OBJECTIVE

To describe the videodermoscopy and Doppler-ultrasound (US) features of a large group of SN.

MATERIAL AND METHODS

A retrospective study of cases of SN collected at our Dermatology department during the period between June 2015 and June 2017 was performed. Clinical images, dermoscopic, videodermoscopic and Doppler-US files were reviewed. For each case, the age of the patient, time since onset, size and dermoscopic pattern of the lesions were recorded. The presence of pulsatility was also evaluated visually on the videodermoscopy.

RESULTS

Two hundred and thirty-three SN in 189 patients were included. The mean age was 39.5 years (range: 10-76 years). Mean size of the lesions was 4.1 ± 2.0 mm. We described three dermoscopic patterns: network, star and looping. Older age, longer time since onset and larger size were found associated with higher frequency of the looping and star patterns compared to that of network pattern (P < 0.01). Pulsatility during videodermoscopy was found in 88 patients (37%). This pulsatility phenomenon was more commonly associated with the looping pattern (64.7%) than star- (40.3%) or network-like patterns (29.9%) (P < 0.001). In Doppler-US studies, a high-flow with arterial biphasic waveform was found.

CONCLUSIONS

In the light of the results, we support that SN could be reconsidered in upcoming classifications as lesions closer to the group of high-flow arteriovenous malformations.

A giant spider nevus in a patient of hepatitis C-related liver cirrhosis: A rare presentation

Spider nevi are benign vascular lesions mostly seen in patients with decompensated liver cirrhosis. Mostly, these are seen in the superior vena cava distribution and are small with pinhead size central vessel. Giant spider nevus is rarely seen and hence this report.

Wilson's Disease in Bangladeshi Children: Analysis of 100 Cases

PURPOSE

To evaluate clinical and laboratory profile of Wilson's disease (WD) in children.

METHODS

This cross sectional study was conducted at Bangabandhu Sheikh Mujib Medical University Hospital. Bangladesh, over a period of 3 years. One hundred consecutive children of WD between 3 to 18 years of age were evaluated.

RESULTS

Mean age was 8.5±1.5 years. Male female ratio was 2:1. Ninety-one percent of patients were Muslim and 9% Hindu. A total of 53% cases of hepatic WD presented between 5 to 10 years of age and most of the neurologic WD manifested in 10-15 years age group. Sixty-nine children presented only with hepatic manifestations, 6 only with neurological manifestations, 14 with both hepatic and neurological manifestation, 10 children was asymptomatic and 1 patient presented with psychiatric features. WD presented as chronic liver disease (CLD) in 42%, CLD with portal hypertension in 34%, acute hepatitis in 20% and fulminant hepatic failure in 4% cases. Stigmata of CLD were found in 18% patients. Keiser-Fleischser ring was found in 76% total patients. Elevated serum transaminase was found in 85% cases, prolonged prothrombin time in 59% cases and hypoalbuminaemia in 53% cases. A total of 73% patients had low serum ceruloplasmin, basal urinary copper of >100 µg/day was found in 81% cases and urinary copper following penicillamine challenge of >1,200 µg/day was found in 92% cases.

CONCLUSION

Majority of studied WD children presented with hepatic manifestation of which 76% presented with CLD. Any child presented with jaundice after the age of 3 years should be investigated for WD.

Genetic variation in the NBS1 gene is associated with hepatic cancer risk in a Chinese population

NBS1 plays important roles in maintaining genomic stability as a key DNA repair protein in the homologous recombination repair pathway and as a signal modifier in the intra-S phase checkpoint. We hypothesized that polymorphisms of NBS1 are associated with hepatic cancer (HCC) risk. The NBS1 rs1805794 C/G polymorphism has been frequently studied in some cancers with discordant results, but its association with HCC has not been investigated. Moreover, studies of the 3'UTR variant rs2735383 have not touched upon HCC. This study examined the contribution of these two polymorphisms to the risk of developing HCC in a Chinese population. NBS1 genotypes were determined in 865 HCC patients and 900 controls and the associations with risk of HCC were estimated by logistic regression. Compared with the rs1805794 GG genotype, the GC genotype had a significantly increased risk of HCC (adjusted odds ratios [OR]=1.41; 95% confidence interval [CI]=1.11-1.80), the CC carriers had a further increased risk of HCC (OR=2.27; 95% CI=1.68-3.14), and there was a trend for an allele dose effect on risk of HCC (p<0.001). Also, we found that the risk effect of rs1805794 CC+CG was more pronounced in HCC patients that drank (OR=2.28, 95% CI=1.55-3.29 for drinkers; OR=1.31, 95% CI=1.00-1.77 for nondrinkers). However, there was no significant difference in genotype frequencies of rs2735383 G/C site between cases and controls. These findings suggest that rs1805794 C/G polymorphism in NBS1 may be a genetic modifier for developing HCC.

Breast cancer and spider telangiectasias at diagnosis and its relation to histopathology and prognosis: a population-based study

Angiogenesis is one of the hallmarks of breast cancer. The status of angiogenesis is important in therapy choice. Spider telangiectasias (telangiectasias) may reflect an increased ability to form vessels. Our first aim was to identify patient and tumor characteristics associated with the occurrence of telangiectasias at the time of breast cancer diagnosis. The second aim was to study the overall survival in relation to the occurrence of telangiectasias at the time of breast cancer diagnosis. A standardized questionnaire was used to interview 1682 consecutive breast cancer patients about risk factors between 1980 and 2009. Occurrence of telangiectasias at the time of breast cancer diagnosis on the upper thorax, head, and/or neck was recorded by one physician. In the cohort, 93 women (5.5%) had telangiectasias. Occurrence of telangiectasias was positively associated with weight, odds ratio (OR) 1.02 (95% confidence interval (CI) 1.00-1.05) per kg, ever-use of oral contraceptives OR 2.67(CI 1.55-4.63) and hormone replacement therapy OR 2.68(CI 1.63-4.39), and negatively associated with parity OR 0.45(CI 0.25-0.79). Telangiectasias were not present in patients with comedo breast cancer. Patients with occurrences of telangiectasias diagnosed before the age of 50 had a statistically non-significant worse overall survival, whereas the patients with occurrences of telangiectasias diagnosed at age 50 or after had a statistically significant better overall survival (P interaction = 0.016). The relationship between the occurrence of telangiectasias and the overall survival in the older patient-group was independent of ever-use of HRT. Hormonal risk factors for breast cancer were associated with the occurrence of spider telangiectasias. The occurrence of telangiectasias may reflect the angiogenic status of the tumor. We hypothesize that telangiectasias could be used as selection criteria for anti-angiogenic therapy in younger breast cancer patients. Therefore, patients with comedo breast cancers maybe a group that may benefit less from anti-angiogenic therapy.

Dermatologic disorders and the liver

Chronic liver disease is associated with several cutaneous manifestations. Although many of these changes are nonspecific, some are associated with distinct liver diseases and correlate with the severity of hepatic pathology. Often the first clue to a liver disease is manifested through skin. Although cirrhosis is associated with spider nevi and palmar erythema, disorders can result in noncirrhotic cutaneous manifestations. It is important for physicians to be familiar with the spectrum of these manifestations, to recognize, help detect, and treat the underlying hepatic disease. This article reviews the medical literature and discusses the spectrum of dermatologic manifestations of liver disorders and their pathogenesis, significance, and treatment.

The significance of cutaneous spider naevi in children

BACKGROUND

Cutaneous spider naevi are commonly considered to be a clinical sign of chronic liver disease. Little is known about their occurrence in children.

AIM

To evaluate the occurrence of spider naevi in children with and without liver disease.

METHODS

The presence of spider naevi was investigated in 460 children, 34 of whom had chronic liver disease.

RESULTS

Of children without liver involvement, 38% had at least one spider naevus. The prevalence of spider naevi increased with age. Of control patients aged 5 to 15 years, 2.5% had more than five spiders present. Although eight of 10 children with cirrhosis had at least one spider naevus, only four of 34 children with chronic liver disease had five or more spiders present. Most spiders were on the hands and very few were >5 mm in size.

CONCLUSIONS

Children with liver disease rarely have large numbers of spider naevi. Although the finding of five or more spider naevi is more common in liver disease, many normal children also have one or more of these lesions.

Spider angiomas in patients with liver cirrhosis: Role of vascular endothelial growth factor and basic fibroblast growth factor

AIM: To investigate whether vascular endothelial growth factor (VEGF) and basic fibroblastic growth factor (bFGF) are associated with spider angiomas in patients with liver cirrhosis.

METHODS: Eighty-six patients with liver cirrhosis were enrolled and the number and size of the spider angiomas were recorded. Fifty-three healthy subjects were selected as controls. Plasma levels of VEGF and bFGF were measured in both the cirrhotics and the controls.

RESULTS: Plasma VEGF and bFGF were increased in cirrhotics compared with controls (122 ± 13 vs. 71 ± 11 pg/mL, P = 0.003 for VEGF; 5.1 ± 0.5 vs. 3.4 ± 0.5 pg/mL, P = 0.022 for bFGF). In cirrhotics, plasma VEGF and bFGF were also higher in patients with spider angiomas compared with patients without spider angiomas (185 ± 28 vs. 90 ± 10 pg/mL, P = 0.003 for VEGF; 6.8 ± 1.0 vs. 4.1 ± 0.5 pg/mL, P = 0.017 for bFGF). Multivariate logistic regression showed that young age and increased plasma levels of VEGF and bFGF were the most significant predictors for the presence of spider angiomas in cirrhotic patients (odds ratio [OR] = 6.64, 95% confidence interval [CI] = 2.02-21.79, P = 0.002; OR = 4.35, 95%CI = 1.35-14.01, P = 0.014; OR = 5.66, 95%CI = 1.72-18.63, P = 0.004, respectively).

CONCLUSION: Plasma VEGF and bFGF are elevated in patients with liver cirrhosis. Age as well as plasma levels of VEGF and bFGF are significant predictors for spider angiomas in cirrhotic patients.
