Many studies have demonstrated that cirrhosis is frequently associated with autonomic dysfunction. The aim of this study was to test autonomic dysfunction in cirrhotic patients by analyzing heart rate variability (HRV), to determine whether or not the degree of autonomic dysfunction is correlated with the severity of disease, and, also, to compare the changes of HRV between survivor and nonsurvivor groups after 2-year follow-up periods. HRV was analyzed using 24-hr ECG recording in 30 cirrhotic patients and 28 normal controls. The changes in HRV parameters including mean normal-to-normal (N-N) interbeat intervals (mean NN), standard deviation of all N-N intervals (SDNN), standard deviation of the average of N-N intervals for each 5-min period over 24 hr (SDANN), root mean square succesive differences (r-MSSD; msec), and percentage of adjacent N-N intervals that are >50 msec apart (pNN50), all as time domain parameters, were evaluated. The cirrhotic patients were also evaluated according to Child-Pugh classification scores as markers of the disease severity. The time-domain measures of HRV in cirrhotic patients were significantly reduced compared with those in the control group (for all parameters; P < 0.001). The severity of disease was associated with reduced HRV measures (for all parameters; P < 0.001). After the 2-year follow-up periods, HRV measurements in cirrhotic patients were significantly much lower in nonsurvivors than in survivors (P < 0.001 for all). We conclude that increasing severity of cirrhosis is associated with a reduction in HRV. This finding may be an indicator of poor prognosis and mortality for cirrhosis.

Increased levels of BNP are more likely related to the severity of disease in non-alcoholic cirrhotic patients. The advanced cirrhosis is associated with more advanced cardiac dysfunction and BNP has prognostic value in progression of cirrhosis.

In previous studies, it has been shown that QT interval prolongation is related to an increased mortality rate in chronic liver disease (CLD). But QT dispersion (QTd) and its clinical significance in CLD has not been well studied. The objectives of this study were to investigate the relation between QTd and severity of the disease and determine its prognostic value in cirrhotic patients. Thirty-three consecutive patients with cirrhosis and 35 sex- and age-matched healthy subjects were studied. QT intervals and QT dispersions were measured on admission, and all intervals were corrected for heart rate according to Bazett's formula. The authors analyzed the potential relationship between QT parameters and the disease severity according to Child-Pugh classification and compared these values between survivors and nonsurvivors after a 3-year follow-up. Child-Pugh classification is used to assess liver function in cirrhosis. Corrected QT (QTc) prolongations were found in 32% of patients with cirrhosis and 5.7% of the healthy controls (p <0.001). The prevalence of increased (>70 ms) corrected QT dispersion (QTcd) was 45% in patients with cirrhosis. According to Child-Pugh criteria: QTd, maximum QT interval (QTmax), corrected QTmax (QTcmax), and QTcd in class C were significantly higher than those of class A and B (p <0.05, for all comparison). But there was no significant difference between class A and B in QTmax, QTcmax, QTd, and QTcd. There were 10 (30%) deaths from all causes during 3-year follow-up in the study group. Cox regression analysis showed that QTd and QTcd were better mortality indicators than QTmax and QTcmax, and Child's classification was the best predictor for mortality among all variables. In conclusion, QT dispersion and corrected QT dispersion parameters were better mortality indicators than other QT interval parameters and also may give additional prognostic information in patients with chronic liver disease.

Metastases from distant primary tumors are rarely the first indicators of cancer. However, cutaneous metastases are not uncommon in cases of internal malignancy. This article describes the case of a 65-year-old man with cutaneous metastasis of cholangiocarcinoma who presented with a scalp ulcer as the only initial sign. This is only the third reported case of cholangiocarcinoma with distant cutaneous metastasis.
