Diagnostic role of CD64 expression on neutrophils as biomarker for blood stream infection in liver cirrhosis: some preliminary findings

Background

The expression of CD64 on neutrophils (nCD64), measured using flow cytometry, has been proposed as a biomarker for bloodstream infections (BSI). However, data regarding its use in the setting of liver cirrhosis are lacking.

Methods

We compared nCD64 levels in 15 cirrhotic patients with BSI to those in 19 controls, including outpatients with stable decompensated cirrhosis without infection. Additionally, we compared nCD64 with C-reactive protein (CRP) and procalcitonin (PCT) in infected hospitalized cirrhotic patients.

Results

Cirrhotic patients with infection had higher levels of nCD64 compared to controls (6.0 [5.4-7.1] vs. 2.0 [1.5-2.2]; p<0.001). Among infected patients, a correlation between nCD64 (AUC=0.934 [0.875-0.982 95% CI]), CRP (AUC=0.972 [0.942-0.993 95% CI]), and PCT (AUC=0.859 [0.739-0.953 95% CI]) was observed. However, in our sample of cirrhotic individuals, nCD64 values were not significantly different between patients with worse prognosis and those with positive outcomes (p=0.448), and its expression was not influenced by Gram stain.

Conclusions

In our cohort, nCD64 appears to be a promising new biomarker for BSI. Additional prospective studies are needed to confirm its role and limitations in conjunction with other biomarkers and rapid microbiology in the diagnostic multidisciplinary pathway for septic cirrhotic patients.

The Lower Survival in Patients With Alcoholism and Hepatitis C Continues in the DAA Era

BACKGROUND

Alcohol liver disease (ALD) may coexist with hepatitis C (HCV) in many transplant recipients (alcoholic cirrhosis with hepatitis C [AHC]). Our objective was to determine whether there were differences in postliver transplantation outcomes of patients with AHC when compared with those with alcoholic cirrhosis (AC) and/or alcoholic hepatitis (AH).

METHODS

Using UNOS explant data sets (2016-2020), the survival probabilities of AC, AH, and AHC were compared by Kaplan-Meier survival analysis. Cox proportional-hazard regression analysis was used to determine outcomes after adjusting for disease confounders. The outcomes were also compared with predirect antiviral agent (DAA) period.

RESULTS

During study period, 8369 biopsy-proven ALD liver transplant recipients were identified. Of those, 647 had AHC (HCV + alcohol), 353 had AH, and 7369 had AC. MELD-Na score (28.7 ± 9.5 versus 23.8 ± 10.7; P  < 0.001) and presence of ACLF-3 (19% versus 11%; P  < 0.001) were higher in AC + AH as compared with AHC. AHC and AC+AH has similar adjusted mortality at 1-y, but 3-y (hazard ratios, 1.76; 95% confidence intervals, 1.32-2.35; P  < 0.0001) and 5-y (hazard ratios, 1.64; 95% confidence intervals, 1.24-2.15; P  = 0.0004) mortality rates were higher in AHC. Survival improved in the DAA era (2016-2020) compared with 2009 to 2013 in AHC, but remained worse in AHC group versus AC and/or AH. Malignancy-related mortality was higher in AHC (15% versus 9.3% in AC) in the DAA era.

CONCLUSIONS

AHC was associated with lower 3- and 5-y post-LT survival as compared with ALD without HCV and the worse outcomes in AHC group continued in the DAA era.

Palliative Care in Kidney and Liver Diseases

The role of palliative care is to recognize patients with advanced illnesses who are at risk for poor outcomes and to alleviate their pain and suffering. Patients with both kidney and liver disease are a very vulnerable population due to the unique pathophysiologic relationship these two organs share, which often leads to an abbreviated life expectancy and a significant symptom burden. These patients face many challenges in their care. This article discusses the importance of prognostication for early palliative care referrals as well as the management of the two most common complaints patients with kidney and liver disease face: pain and ascites.
