Conflicting results exist with regard to metabolic acid-base status in liver cirrhosis, when the classic concept of acid-base analysis is applied. The influence of the common disturbances of water, electrolytes and albumin on acid-base status in cirrhosis has not been studied. The aim of this study was to clarify acid-base status in cirrhotic patients by analyzing all parameters with possible impact on acid-base equilibrium. ⋯ A balance of offsetting acidifying and alkalinizing metabolic acid-base disorders leaves the net metabolic acid-base status unchanged in cirrhosis.

Hepatitis B virus (HBV) and hepatitis C virus (HCV) infection are two important factors in the development of hepatocellular carcinoma (HCC). The carcinogenic mechanism of HBV and HCV is considered to be different. It is interesting to compare the recurrence after hepatic resection in patients with small HCC who were infected with HBV or HCV. ⋯ HCV infection, as compared with HBV infection, had a higher cumulated recurrence after hepatic resection in patients with small HCC. Low serum albumin level was significantly associated with recurrence among these patients.

Nitric oxide (NO) has been implicated in cirrhosis and might be implicated in renal failure end-stage cirrhosis. ⋯ Both inhibitors improved renal function, although AG displayed a better effect and did not aggravate liver function. We concluded that NOS isoforms are implicated in the renal pathophysiologic events induced by ALD.

Comparative Study
Circulating concentrations of interleukin-18, interleukin-18 binding protein, and gamma interferon in patients with alcoholic hepatitis.
Alcoholic hepatitis (AH) is associated with dysregulated inflammatory and immune responses. interleukin-18 (IL-18), described as gamma interferon (gammaIFN)-inducible factor, and its natural antagonist, IL-18 binding protein (IL-18 BP), has not been fully studied in patients with AH. Thus, our aim was: (i) to determine plasma values of IL-18, IL-18 BP, gammaIFN, and tumor necrosis factor alpha (TNF)-alpha in patients hospitalized for biopsy-proven AH; (ii) to correlate these cytokines with the severity of AH, as assessed by Maddrey's discriminant function (DF), the degree of liver failure using the Child-Pugh score and blood neutrophils; (iii) to compare cytokines values in survivors and non-survivors. ⋯ In cirrhotic patients with AH, IL-18, IL-18 BP, and TNFalpha correlate to the hepatitis severity and to the degree of liver failure. High IL-18 BP and TNFalpha at hospital admission in non-survivors suggest it may be of prognostic value.

The model for end-stage liver disease (MELD) score is a useful tool to assess prognosis in critically ill cirrhotic patients. However, its short-term prognostic superiority over the traditional Child-Turcotte-Pugh (CTP) score has not been definitely confirmed. The creatinine serum level is an important predictor of survival in patients with liver cirrhosis. ⋯ Adding creatinine values to the CTP slightly improves the prognostic usefulness of the traditional CTP score alone. The MELD score has a short-term prognostic yield that is better than what is provided by both the CTP and CTP creatinine-modified scores, even in cirrhotic patients who are not critically ill. The positive results obtained by using the MELD score were confirmed even after excluding patients with impaired renal function.
