Neutrophil-lymphocyte ratio is associated with worse outcomes in patients with cirrhosis: insights from the PRO-LIVER Registry

Background: Liver cirrhosis (LC) is a leading global cause of morbidity and mortality, with inflammation playing a key role in disease progression and clinical complications of LC. The Neutrophil/Lymphocyte Ratio (NLR), a readily available marker of systemic inflammation, has been linked to short-term adverse outcomes in LC, but data on long-term follow-up are limited. This study aimed to investigate the relationship between NLR and long-term all-cause mortality in an unselected cohort of LC patients. Methods: Data were gathered from the Italian multicenter observational study "PRO-LIVER". Patients with available data to calculate NLR at baseline were included. Baseline clinical determinants of NLR and the association of NRL with all-cause mortality at 2-year follow-up were evaluated. Results: From the overall cohort (n = 753), 506 patients with LC (31% female, mean age 64.8 ± 11.9 years) were included in the analysis. Median value of NLR was 2.42 (Interquartile Range [IQR]: 1.61-3.52). At baseline, patients with NLR ≥ 2.42 were more likely to have Child-Pugh B or C, hepatocellular carcinoma (HCC), or portal vein thrombosis (PVT). After a median follow-up of 21 months, 129 patients died: 44 (17%) with NLR < 2.42 and 85 (34%) with NLR ≥ 2.42 (p < 0.001). At multiple-adjusted Cox regression analysis, NLR ≥ 2.42 was independently associated with all-cause mortality (HR: 1.65; 95% CI: 1.12-2.44; p = 0.012), along with age, Child-Pugh C class, HCC and PVT. Conclusions: NLR is associated with long-term all-cause mortality in LC. NLR may serve as a potentially easily available tool to aid risk refinement in LC

Serum Albumin Is Inversely Associated With Portal Vein Thrombosis in Cirrhosis

We analyzed whether serum albumin is independently associated with portal vein thrombosis (PVT) in liver cirrhosis (LC) and if a biologic plausibility exists. This study was divided into three parts. In part 1 (retrospective analysis), 753 consecutive patients with LC with ultrasound-detected PVT were retrospectively analyzed. In part 2, 112 patients with LC and 56 matched controls were entered in the cross-sectional study. In part 3, 5 patients with cirrhosis were entered in the in vivo study and 4 healthy subjects (HSs) were entered in the in vitro study to explore if albumin may affect platelet activation by modulating oxidative stress. In the 753 patients with LC, the prevalence of PVT was 16.7%; logistic analysis showed that only age (odds ratio [OR], 1.024; P = 0.012) and serum albumin (OR, -0.422; P = 0.0001) significantly predicted patients with PVT. Analyzing the 112 patients with LC and controls, soluble clusters of differentiation (CD)40-ligand (P = 0.0238), soluble Nox2-derived peptide (sNox2-dp; P < 0.0001), and urinary excretion of isoprostanes (P = 0.0078) were higher in patients with LC. In LC, albumin was correlated with sCD4OL (Spearman's rank correlation coefficient [r(s)], -0.33; P < 0.001), sNox2-dp (r(s), -0.57; P < 0.0001), and urinary excretion of isoprostanes (r(s), -0.48; P < 0.0001) levels. The in vivo study showed a progressive decrease in platelet aggregation, sNox2-dp, and urinary 8-iso prostaglandin F2 alpha-III formation 2 hours and 3 days after albumin infusion. Finally, platelet aggregation, sNox2-dp, and isoprostane formation significantly decreased in platelets from HSs incubated with scalar concentrations of albumin. Conclusion: Low serum albumin in LC is associated with PVT, suggesting that albumin could be a modulator of the hemostatic system through interference with mechanisms regulating platelet activation

Are elderly patients poor candidates for pegylated interferon plus ribavirin in the treatment of chronic hepatitis C?

Elderly patients with chronic hepatitis C receiving combined treatment with IFN and RBV have a higher likelihood of side effects and a significantly lower rate of virological response at the end of the treatment and 6 months afterward than younger adults

Clinical course and outcome of autoimmune hepatitis/primary sclerosing cholangitis overlap syndrome

Autoimmune hepatitis/primary sclerosing cholangitis (AIH/PSC) overlap syndrome is a relatively uncommon variant of PSC. AIM: To evaluate the natural history of AIH/PSC overlap syndrome compared to a group of "classical" PSC. METHODS: Forty-one consecutive PSC patients, with a regular follow-up of at least 2 years, were prospectively included in the study. Among these, 7 fulfilled the criteria for AIH/PSC overlap syndrome. RESULTS: The AIH/PSC overlap group significantly differed from the "classical" PSC group in the following parameters: mean age at presentation (21.4 +/- 5.0 vs 32.3 +/- 10 years, p < 0.01), AST 191.0 +/- 14.8 vs 48.9 +/- 34.5 U/L, p < 0.005), ALT (357.0 +/- 26.5 vs 83.7 +/- 60.7 U/L, p < 0.005) and serum IgG (25.6 +/- 4.7 vs 12.9 +/- 6.0 mg/dl, p < 0.0001). The mean follow-up was similar in the 2 groups (93.3 +/- 65.9 vs 98.1 +/- 65.9 months respectively). Treatment included immunosuppression + ursodeoxycholic acid (UDCA) in the AIH/PSC overlap patients, and UDCA in the "classical" PSC group. Deaths were recorded only in the classical PSC group. The median survival in the latter group was 207 months (95% C.I. 87.6-326.4). The major events during the follow-up included: OLTx (1/7 vs 6/34), and neoplasms (only in the group of "classical" PSC). The new Mayo score prognostic index only increased significantly during follow-up in the "classical" PSC group (r2 0.8117, p < 0.01) CONCLUSION: Patients with AIH/PSC overlap syndrome seem to benefit from immunosuppression + UDCA therapy, survival is apparently better than in "classical" PSC condition

Lack of higher frequency of the chemokine receptor 5-delta32/delta32 genotype in hepatitis C.

PURPOSE: An elevated frequency of the CCR5-Delta32 mutation in German patients with hepatitis C with viremia has been reported. The aim of the present study was to verify whether this mutation occurs in an Italian population with hepatitis C and whether it is an adverse host factor indicative of severity of liver disease and response to antiviral therapy. STUDY: The authors amplified 189-bp (wild-type) and 157-bp (Delta32 deletion) fragments of the CCR5 gene by polymerase chain reaction in 130 patients with chronic hepatitis C. Comparisons were drawn with 110 blood donors and 135 patients with primary biliary cirrhosis. RESULTS: Four (3.1%) patients with chronic hepatitis C and 1 blood donor (0.9%) were CCR5-Delta32 homozygous, whereas there was no CCR5-Delta32 homozygosity among primary biliary cirrhosis patients; the wild-type gene was present in a similar percentage in the 3 groups of patients without any significant difference (83.1% vs 90.4% vs 83.6%, respectively). Among the patients with chronic hepatitis C, no significant correlation was found between CCR5-Delta32 homozygosity and the following parameters: histologic grade/stage, hepatitis C virus genotype, viral load, serum aspartate aminotransferase, serum alanine aminotransferase, and serum gamma-glutamyltransferase. Ninety-five patients received a standard antiviral protocol with pegylated interferon (PEG Intron)+ribavirin; a sustained response was achieved in 59 patients (62.1%), and the remainder did not respond or experienced a relapse. Response to treatment was not influenced by CCR5-Delta32 deletion. CONCLUSION: No greater frequency of CCR5-Delta32 homozygosity was seen in an Italian population of patients with chronic hepatitis C. This mutation does not seem to influence either the overall severity of liver disease or the response to viral therapy

Is hepatitis C virus a risk factor for thyroid autoimmunity?

The role of hepatitis C virus (HCV) in inducing thyroid autoimmunity is still under discussion and to assess the prevalence of thyroid autoantibodies and thyroid disease in the general population and to analyse the role of HCV in inducing thyroid autoimmunity. We studied 697 subjects residing in Arsita (a small town in central Italy). Thyroid autoantibodies and nonorgan-specific autoantibodies (NOSAs) were tested in each subject, who were also screened for anti-HCV antibodies; all subjects found positive to HCV-RNA were considered as being HCV-infected. Thyroid function tests were performed in all subjects positive for thyroid autoantibody. Seventy-one subjects were found HCV-positive; four of these (5.6%) were positive for at least one thyroid autoantibody, as opposed to 7 (4.9%) of the 142 sex- and age-matched controls of the same population (P = n.s.). Thyroid dysfunction was found in 2/4 HCV-positive, and in 1/7 HCV-negative subjects with thyroid autoantibodies (P = n.s.). NOSAs were significantly more common in HCV-positive than in HCV-negative subjects (P < 0.0001). Hence HCV per se is not responsible for thyroid autoimmune dysfunction, whereas HCV does seem to induce NOSAs. It should be taken into account, however, that the phenotypic expression of autoimmune diseases is obviously influenced by a number of risk factors, including genetic predisposition, female sex and infectious agents, that could trigger the onset of the disease

Type I autoimmune hepatitis:clinical course and outcome in an Italian multicentre study

BACKGROUND: Many reports of autoimmune hepatitis (AIH) were written in the 'pre-Hepatitis C era' and data on the natural history are still incomplete. AIM: To evaluate the clinical presentation and the natural history of type I AIH. METHODS: Seventy-three consecutive patients with a regular follow-up of at least 2 years were prospectively included in the study. The mean follow-up was 91 +/- 61 months. RESULTS: Patients with 'acute' onset at presentation were significantly older than patients with 'chronic' onset (P < 0.05) and had significantly higher serum levels of transaminase, gamma-glutamyltransferase and bilirubin; Prothrombin time was significantly lower in the said group compared with AIH patients with 'chronic' onset. In 4 of 63 (6.3%) female patients, AIH had the onset during pregnancy; in all of them the outcome of pregnancy was favourable. The major events during the follow-up included oesophageal varices (n = 9) and ascites (n = 4), and 60 patients remained in remission while receiving immunosuppression. None of the patients died during the follow-up, but seven patients were transplanted. The cumulative transplant-free probability of survival was 73.5% at 280 months. CONCLUSIONS: Elderly patients have more frequently an acute onset at presentation. Survival in AIH is apparently good; with early diagnosis, and improved medical therapy, liver transplantation for AIH will become a rare event in future
