Poor immune response to coronavirus disease vaccines in decompensated cirrhosis patients and liver transplant recipients.

ABSTRACT:

Background and aims

Recent studies have reported poor humoral immune response to mRNA vaccines in patients with chronic liver disease (CLD). However, the immunogenicity of ChAdOx1 (vector-based) and BBV152 (inactivated virus) vaccines in patients with CLD and liver transplant recipients (LTRs) is unknown. Therefore, we aimed to assess the immunogenicity of ChAdOx1 and BBV152 vaccines in patients with CLD (including cirrhosis patients) and LTRs.

Methods

In this single-center prospective study, consecutive completely vaccinated (ChAdOx1 or BBV152) non-cirrhosis CLD patients, those with cirrhosis, and LTRs were compared with matched healthy controls for anti-spike antibody and cellular response.

Results

Sixty healthy individuals, 50 NCCLD patients, 63 compensated and 50 decompensated cirrhosis, and 17 LTRs were included. The proportion of non-responders was similar among the healthy control (8 %), non-cirrhosis CLD (16 %), and compensated cirrhosis groups (17.5 %;p = 0.3). However, a higher proportion of patients with decompensated cirrhosis (34 %) and LTRs (59 %) were non-responders than the healthy controls (p = 0.001). Cluster of differentiation (CD) 4-effector cells were lower in patients with non-cirrhosis CLD and compensated cirrhosis. CD4-naïve, CD4-effector, B, and B-memory cells were lower in the decompensated cirrhosis group. Although the central memory cells were higher in the decompensated cirrhosis group, they could not differentiate into effector cells. CD4- and CD8-naïve cells were higher in the marrow in the LTRs, while the CD4-effector memory cells and CD4- and CD8-effector cells were lower in the LTRs. Furthermore, B cells were more deficient in the LTRs, suggesting poor antibody response.

Conclusion

Patients with decompensated cirrhosis and LTRs demonstrated suboptimal humoral and cellular immune responses against recombinant and inactivated COVID-19 vaccines.

Project description:Background: Acquired dysfunctional immunity in cirrhosis predisposes patients to frequent bacterial infections, especially spontaneous bacterial peritonitis (SBP), leading to systemic inflammation that is associated with poor outcome. But systemic inflammation can also be found in the absence of a confirmed infection. Detection of bacterial DNA has been investigated as a marker of SBP and as a predictor of prognosis. Data is, however, contradictory. Here we investigated whether levels of IL-6 and IL-8 putatively produced by myeloid cells in ascites are associated with systemic inflammation and whether inflammation depends on the presence of specific bacterial DNA. Methods and Materials: We enrolled 33 patients with decompensated liver cirrhosis from whom we collected paired samples of blood and ascites. IL-6 and IL-8 were measured in serum samples of all patients using ELISA. In a subset of 10 representative patients, bacterial DNA was extracted from ascites and whole blood, followed by 16S rRNA gene amplicon sequencing. Results: There were significantly higher levels of IL-6 in ascites fluid compared to blood samples in all patients. Interestingly, IL-6 levels in blood correlated tightly with disease severity and surrogates of systemic inflammation, while IL-6 levels in ascites did not. Moreover, patients with higher blood CRP levels showed greater SBP prevalence compared to patients with lower levels, despite similar positive culture results. Bacterial richness was also significantly higher in ascites compared to the corresponding patient blood. We identified differences in microbial composition and diversity between ascites and blood, but no tight relationship with surrogates of systemic inflammation could be observed. Discussion: In decompensated cirrhosis, markers of systemic inflammation and microbiota composition seem to be dysregulated in ascites and blood. While a relationship between systemic inflammation and microbiota composition seems to exist in blood, this is not the case for ascites in our hands. These data may suggest compartmentalization of the immune response and interaction of the latter with the microbiota especially in the blood compartment.

Project description:ImportanceThe burden of end-of-life care for patients with cirrhosis is increasing in the US, and most of these patients, many of whom are not candidates for liver transplant, die in institutions receiving aggressive care. Advance care planning (ACP) has been associated with improved end-of-life outcomes for patients with other chronic illnesses, but it has not been well-characterized in patients with decompensated cirrhosis.ObjectiveTo describe the experience of ACP in patients with decompensated cirrhosis at liver transplant centers.Design, setting, and participantsFor this multicenter qualitative study, face-to-face semistructured interviews were conducted between July 1, 2017, and May 30, 2018, with clinicians and patients with decompensated cirrhosis at 3 high-volume transplant centers in California. Patient participants were adults and had a diagnosis of cirrhosis, at least 1 portal hypertension-related complication, and current or previous Model for End-Stage Liver Disease with sodium score of 15 or higher. Clinician participants were health care professionals who provided care during the illness trajectory.Main outcomes and measuresExperiences with ACP reported by patients and clinicians. Participants were asked about the context, behaviors, thoughts, and decisions concerning elements of ACP, such as prognosis, health care preferences, values and goals, surrogate decision-making, and documentation.ResultsThe study included 42 patients (mean [SD] age, 58.2 [11.2] years; 28 men [67%]) and 46 clinicians (13 hepatologists [28%], 11 transplant coordinators [24%], 9 hepatobiliary surgeons [20%], 6 social workers [13%], 5 hepatology nurse practitioners [11%], and 2 critical care physicians [4%]). Five themes that represent the experiences of ACP were identified: (1) most patient consideration of values, goals, and preferences occurred outside outpatient visits; (2) optimistic attitudes from transplant teams hindered the discussions about dying; (3) clinicians primarily discussed death as a strategy for encouraging behavioral change; (4) transplant teams avoided discussing nonaggressive treatment options with patients; and (5) surrogate decision makers were unprepared for end-of-life decision-making.Conclusions and relevanceThis study found that, despite a guarded prognosis, patients with decompensated cirrhosis had inadequate ACP throughout the trajectory of illness until the end of life. This finding may explain excessively aggressive life-sustaining treatment that patients receive at the end of life.
