RESUMO
AIM: To detect immune-related adverse events (irAEs) early and treat them appropriately, our institute established an irAE-focused multidisciplinary toxicity team in cooperation with various departments. This study aimed to evaluate a consultation system involving a team of hepatologists in terms of its utility for the management of severe immune checkpoint inhibitor (ICI)-induced liver toxicity. METHODS: To analyze the diagnosis and treatment of severe ICI-induced liver toxicity (Grade 2 requiring corticosteroid therapy and Grade 3 or higher), we examined patients' clinical courses before and after the hepatologist consultation system was established (pre-period, September 2014 to February 2019; post-period, March 2019 to March 2023). RESULTS: The median follow-up period was 392 days. Of the 1247 patients with advanced malignancies treated with ICIs, 66 developed severe ICI-induced liver toxicity (n = 22 and 44 in the pre- and post-periods, respectively). In the pre-period, hepatologist consultations were sought for 15/22 patients, whereas in the post-period, 42/44 patients were referred to and treated by hepatologists. The time from the onset of liver toxicity to the consultation was significantly shorter in the post-period than in the pre-period (mean 1.9 vs. 6.5 days, respectively; p = 0.012). The number of patients with a biopsy-confirmed diagnosis of ICI-induced liver toxicity was significantly higher in the post-period than in the pre-period (n = 22 vs. n = 3, respectively; p = 0.006). Finally, there were no cases of immune-related cholangitis in the pre-period, compared to five cases in the post-period. CONCLUSION: A hepatologist consultation system in an irAE-focused multidisciplinary toxicity team is useful for managing severe ICI-induced liver toxicity.
RESUMO
With the widespread use of immune checkpoint inhibitors (ICIs), liver injury (ICI-induced liver injury) as an immune-related adverse event has become a major concern in clinical practice. Because severe cases of liver injury require administration of corticosteroids, a comprehensive evaluation is crucial, including clinical course, blood and imaging tests, and if necessary, pathological examination through liver biopsy. As with liver injury induced by other drugs, classification of injury type by R-value is useful in deciding treatment strategies for ICI-induced liver injury. Histologically, the most representative feature is an acute hepatitis-like hepatocellular injury, characterized by diffuse lobular inflammation accompanied by CD8-positive T lymphocytes. Another condition that can cause liver injury during ICI treatment is cholangitis accompanied by non-obstructive bile duct dilatation and bile duct wall thickening. Many cases of ICI-induced cholangitis are classified as non-hepatocellular injury type, and they have been reported to respond poorly to corticosteroids. It is essential that gastroenterologists/hepatologists and doctors in various departments work in cooperation to develop a system that achieves early diagnosis and appropriate treatment of ICI-induced liver injury.
RESUMO
Immune-related sclerosing cholangitis (irSC) is relatively rare and its clinical characteristics are not well known. In this study, we aimed to summarize the clinical features of irSC. Clinical data were collected retrospectively from 1,393 patients with advanced malignancy treated with immune-checkpoint inhibitors (ICIs) between August 2014 and October 2021. We analyzed patients with immune-related adverse events of liver injury (liver-irAEs) and compared irSC and non-irSC groups. Sixty-seven patients (4.8%) had a liver-irAE (≥ grade 3) during the follow-up period (median, 262 days). Among these, irSC was observed in eight patients (11.9%). All patients in the irSC group were treated with anti-PD-1/PD-L1 antibodies. Compared with the non-irSC group, the irSC group showed mainly non-hepatocellular liver injury (87.5 % vs 50.8 %, P = 0.065), and had elevated serum inflammatory markers (e.g., CRP and NLR) and biliary enzymes (e.g., GGTP and ALP) at the onset of liver-irAEs. Furthermore, most patients with irSC had abdominal pain. In the non-irSC group, the liver injury of 23 patients improved only with the discontinuation of ICIs, and 22 patients improved with medication including prednisolone (PSL). Conversely, almost all patients (n=7) in the irSC group were treated with PSL, but only two patients experienced an improvement in liver injury. We found that irSC is characterized by a non-hepatocellular type of liver injury with abdominal pain and a high inflammatory response and is refractory to treatment. Further examination by imaging is recommended to detect intractable irSC in cases with these characteristics.

BACKGROUND AND AIM: Immune-related liver injury (liver-irAE) is a clinical problem with a potentially poor prognosis. METHODS: We retrospectively collected clinical data from patients treated with immune checkpoint inhibitors between September 2014 and December 2021 at the Nagoya University Hospital. Using an unsupervised machine learning method, the Gaussian mixture model, to divide the cohort into clusters based on inflammatory markers, we investigated the cumulative incidence of liver-irAEs in these clusters. RESULTS: This study included a total of 702 patients. Among them, 492 (70.1%) patients were male, and the mean age was 66.6 years. During the mean follow-up period of 423 days, severe liver-irAEs (Common Terminology Criteria for Adverse Events grade ≥ 3) occurred in 43 patients. Patients were divided into five clusters (a, b, c, d, and e). The cumulative incidence of liver-irAE was higher in cluster c than in cluster a (hazard ratio [HR]: 13.59, 95% confidence interval [CI]: 1.70-108.76, P = 0.014), and overall survival was worse in clusters c and d than in cluster a (HR: 2.83, 95% CI: 1.77-4.50, P < 0.001; HR: 2.87, 95% CI: 1.47-5.60, P = 0.002, respectively). Clusters c and d were characterized by high temperature, C-reactive protein, platelets, and low albumin. However, there were differences in the prevalence of neutrophil count, neutrophil-to-lymphocyte ratio, and liver metastases between both clusters. CONCLUSIONS: The combined assessment of multiple markers and body temperature may help stratify high-risk groups for developing liver-irAE.

It remains unclear whether severe liver immune-related adverse events (liver-irAEs) can affect the prognosis in nonsmall cell lung carcinoma (NSCLC) patients. Of the 365 NSCLC patients treated with immune checkpoint inhibitors (ICIs), 19 suffered from severe liver-irAEs (grade ≥3). The median time-to-onset of liver-irAEs was 53 days postinjection of the first ICI. The progression-free survival and overall survival of the liver-irAEs group (median 69 and 262 days, respectively) were significantly worse than the nonliver-irAEs group (128 and 722 days; P = 0.010 and P = 0.007; respectively). In conclusion, liver-irAEs were associated with poor prognosis in NSCLC patients.

Notch signaling receptors, ligands, and their downstream target genes are dysregulated in pancreatic ductal adenocarcinoma (PDAC), suggesting a role of Notch signaling in pancreatic tumor development and progression. However, dysregulation of Notch signaling by post-translational modification of Notch receptors remains poorly understood. Here, we analyzed the Notch-modifying glycosyltransferase involved in the regulation of the ligand-dependent Notch signaling pathway. Bioinformatic analysis revealed that the expression of epidermal growth factor (EGF) domain-specific O-linked N-acetylglucosamine (EOGT) and Lunatic fringe (LFNG) positively correlates with a subset of Notch signaling genes in PDAC. The lack of EOGT or LFNG expression inhibited the proliferation and migration of Panc-1 cells, as observed by the inhibition of Notch activation. EOGT expression is significantly increased in the basal subtype, and low expression of both EOGT and LFNG predicts better overall survival in PDAC patients. These results imply potential roles for EOGT- and LFNG-dependent Notch signaling in PDAC.

BACKGROUND: Liver fibrosis is an important risk factor for the development of hepatocellular carcinoma (HCC) after sustained virologic response (SVR) in patients with persistent hepatitis C virus (HCV) infection. However, as the degree of liver fibrosis changes following the eradication of HCV after SVR, it is unclear whether the prediction of HCC development based on liver fibrosis at baseline remains valid. METHODS: In 522 patients who achieved SVR by interferon-based anti-HCV therapy, the Fibrosis-4 Index for Liver Fibrosis (FIB-4 index) was updated annually by recalculation based on laboratory values after SVR. The incidence of HCC was reassessed annually based on the updated FIB-4 index. RESULTS: The percentage of patients with mild liver fibrosis (FIB-4 index <1.45) increased annually after SVR, whereas the percentage of patients with advanced liver fibrosis (FIB-4 index ≥3.25) decreased. The incidences of HCC based on the FIB-4 index remained constant between the time of SVR and subsequent annual updates. No patients developed HCC after SVR if the FIB-4 index decreased to <1.45. CONCLUSIONS: The FIB-4 index retained its predictive ability for the risk of HCC when recalculated after SVR, despite the decrease in patients with high FIB-4 index values. Dynamic assessment of the FIB-4 index can be useful in the surveillance of HCC after SVR. Patients with a FIB-4 index <1.45 did not develop HCC even by the regression from advanced fibrosis after SVR. Further studies will be necessary to confirm these findings, which may result in a decrease in the number of patients in whom surveillance is required.

BACKGROUND & AIMS: It remains controversial whether the eradication of hepatitis C virus (HCV) by interferon (IFN)-free anti-HCV therapy using direct-acting antivirals (DAAs) suppresses or promotes hepatocellular carcinoma (HCC) development. We investigated the influence of HCV eradication by DAA therapy on HCC development, by observing changes of non-hypervascular hypointense nodules (NHHNs) by gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (EOB-MRI). METHODS: A total of 401 patients treated with DAA therapy who did not have a history of HCC were enrolled in this prospective cohort study. All patients underwent EOB-MRI prior to the start of DAA therapy and were followed up periodically after therapy. The progression of NHHNs detected at baseline to typical HCC, as indicated by hypervascularization and the incidence of newly emergent NHHNs, was analyzed. RESULTS: In comparison of patients who achieved sustained virologic response (SVR) with propensity score-matched patients with persistent HCV infection, there was no difference in the incidence of hypervascularization of NHHNs to typical HCC among patients who had NHHNs at baseline. Among patients who did not have NHHNs at baseline, the incidence of the new emergence of NHHNs did not differ between study patients and propensity score-matched patients with persistent HCV infection. CONCLUSIONS: During a 2-year observation period after SVR, the eradication of HCV by IFN-free DAA therapy did not suppress or enhance HCC development. (UMIN000017020).

AIM: Several interferon (IFN)-free, all-oral regimens with direct acting antivirals (DAAs) for chronic hepatitis C virus (HCV) infection also include ribavirin (RBV). We investigated the influence of renal dysfunction on virologic efficacy and adverse effects in 189 patients with HCV genotype 2 infection who received combination RBV-DAA regimens. METHODS: The incidence of RBV-induced anemia, RBV dose reduction, and virologic efficacy were compared according to baseline renal function as defined by the estimated glomerular filtration rate (eGFR). RESULTS: Patients with renal dysfunction (eGFR = 30-59 mL/min/1.73 m2 ) had higher rate of RBV dose reduction and more marked decreases in hemoglobin levels. These findings were more pronounced in patients with the ITPA CC genotype, who are more sensitive to RBV-induced anemia. Although there were no statistically significant differences in sustained virologic response (SVR) rates according to renal function overall (P = 0.1650), the SVR rate was significantly lower in patients who required RBV dose reduction than in those who did not (P < 0.0001). CONCLUSIONS: Baseline renal dysfunction could unfavorably affect the outcomes of RBV-DAA in patients with chronic HCV infection due to the increased risk of RBV dose reduction, even in the era of IFN-free DAA regimens.
RESUMO
BACKGROUND & AIMS: Surveillance reportedly has benefit on survival in patients with hepatocellular carcinoma (HCC), even after adjustment for lead-time bias. However, previous adjustment for lead-time bias using tumour volume doubling time (TVDT) had inherent problem in accuracy. We evaluated survival benefit of HCC surveillance with newly developed approach for adjusting lead-time bias. In addition, survival benefit was evaluated according to HCC aetiology and liver function. METHODS: A total of 3899 patients were studied. TVDT was calculated in 255 study patients with ≥2 tumour size measurements before the diagnosis of HCC. Adjusted survival time was calculated based on TVDT, as the time from when HCC was assumed to be 5 mm to death or last follow-up. Survival rates based on this adjusted survival time were compared between the surveillance and nonsurveillance groups and categorized by HCC aetiology and liver function. RESULTS: Calculated TVDT varied widely by study patients (median 141.9, IQR, 73.1-261.7 days). Survival rates based on adjusted survival time were higher in the surveillance group overall and by patients HCC aetiology. Whereas adjusted survival rates were higher in the surveillance group in Child-Pugh class A patients, the survival benefit was smaller in Child-Pugh class B patients and not statistically significant in Child-Pugh class C patients. CONCLUSIONS: The survival benefit of surveillance for patients with HCC was demonstrated after adjustment for lead-time bias with novel, more accurate methodology. However, the benefits differed based on liver function and may vary largely by patients because of wide variation in TVDT.

BACKGROUND AND AIM: On-treatment response of serum hepatitis C virus (HCV) is reportedly less useful to predict the outcome of anti-HCV therapy with interferon (IFN)-free regimen with direct-acting antivirals than with IFN-based regimens in clinical trials. We evaluated the significance of very early viral response after the start of therapy, which indicates direct HCV response to the drugs, on therapeutic outcome. METHODS: Reductions in serum HCV-RNA levels were measured at 1 day after the start of therapy in 544 patients who underwent IFN-free direct-acting antiviral regimens. The association between these reductions and the achievement or failure of sustained virologic response (SVR) was evaluated. RESULTS: Patient characteristics did not influence 1-day reduction in serum HCV-RNA except for liver fibrosis. There was no difference in 1-day HCV reduction between SVR and non-SVR patients treated with a 24-week regimen. In contrast, in patients treated with a 12-week regimen, 1-day reduction was significantly greater in SVR than in non-SVR patients (P = 0.0013) and was predictive of SVR versus non-SVR (area under the receiver-operating characteristics curve: 0.80). CONCLUSIONS: Whereas the reduction in serum HCV-RNA levels at 1 day after the start of therapy was not associated with treatment outcomes in patients who underwent a 24-week regimen of IFN-free therapy, there was an association in patients receiving a 12-week regimen, and this reduction was predictive of SVR, thus potentially serving as a factor to identify patients at risk of treatment failure.

The aim of the present study was to evaluate the prognostic significance of serum markers that reflect tumor progression, liver function, or liver fibrosis in patients with hepatocellular carcinoma (HCC), focusing on how their impact changes over time after diagnosis. Alpha-fetoprotein (AFP), des-gamma-carboxy prothrombin (DCP), albumin-bilirubin (ALBI) score, aspartate aminotransferase to platelet ratio index (APRI), and FIB-4 index were measured at the time of initial non-recurrent HCC diagnosis in 1669 patients between 1997 and 2016. Survival rates after diagnosis were compared after stratifying patients by these markers. Time-dependent receiver-operating characteristics (ROC) analysis was carried out to assess how these markers predict patient survival or death. Serum AFP and DCP levels, ALBI score, and APRI and FIB-4 index were strongly correlated with HCC progression, liver function, and degree of liver fibrosis, respectively. Survival rates after diagnosis were significantly different when patients were stratified by these markers. In the time-dependent ROC analysis, AFP and DCP had a high prognostic impact within 3 years of diagnosis but the impact decreased thereafter. In contrast, APRI and FIB-4 index had higher prognostic impact 10 years after diagnosis. ALBI score had a high prognostic impact throughout the study period. Time-dependent ROC analysis clearly showed changes in the prognostic importance of serum markers based on the duration after diagnosis. Whereas the prognostic impact of tumor progression markers was strong in the short term, liver fibrosis markers had higher prognostic impact long after diagnosis. Liver function had constant prognostic impact on patient survival after diagnosis.

BACKGROUND AND AIM: There is insufficient research on whether direct-acting antiviral (DAA) therapy can improve liver fibrosis in patients with chronic hepatitis C virus (HCV). We evaluated sequential changes in liver stiffness using shear wave elastography in patients with HCV who received DAA therapy. METHODS: A total of 210 patients with HCV who received daclatasvir and asunaprevir therapy and achieved sustained virological response (SVR) were analyzed. Liver stiffness, as evaluated by shear wave elastography, and laboratory data were assessed before treatment (baseline), at end of treatment (EOT), and at 24 weeks after EOT (SVR24). RESULTS: Alanine aminotransferase levels (ALT) decreased over time, and there were significant differences between baseline and EOT and between EOT and SVR24. Although platelet counts did not significantly differ between baseline and EOT, they increased significantly from EOT to SVR24. The median (interquartile range) liver stiffness values at baseline, EOT, and SVR24 were 10.2 (7.7-14.7), 8.8 (7.1-12.1), and 7.6 (6.3-10.3) kPa, respectively (P < 0.001, baseline vs EOT; P < 0.001, EOT vs SVR24). Additionally, in patients with ALT ≤ 30 (indicating low necroinflammatory activity in the liver) and Fibrosis-4 index > 2.0 (n = 75), the liver stiffness values at baseline, EOT, and SVR24 were 9.6 (7.7-15.2), 9.2 (7.3-12.1), and 7.7 (6.3-10.1) kPa, respectively (P < 0.001, baseline vs EOT; P < 0.001, EOT vs SVR24). CONCLUSION: These results suggest that early improvement of liver stiffness starts during the administration of DAAs in patients who achieve SVR, and this effect is particularly pronounced in patients with progressive liver fibrosis.

BACKGROUND: Endoscopic variceal ligation and sclerotherapy are recommended for esophagogastric variceal bleeding (EGVB) in cirrhosis but can be complicated by early rebleeding and death. This study aimed to identify noninvasive markers accurately predicting early rebleeding and mortality after endoscopic hemostasis for EGVB. METHODS: Among 116 patients with endoscopically confirmed EGVB and endoscopic hemostasis, various noninvasive markers were calculated, and their predictive accuracy was compared by receiver-operating characteristic curve analysis. Endpoints included 5-day rebleeding, 5-day mortality, 6-week rebleeding, and 6-week mortality. RESULTS: The median age was 63 years. Child-Pugh class B and C patients accounted for 40.5% and 34.5%, respectively. Only the aspartate aminotransferase-to-platelet ratio index (APRI) significantly predicted 5-day rebleeding, with an area under the curve (AUC) of 0.777 (95% confidence interval [CI]: 0.537-1). The model for end-stage liver disease-Na (MELD-Na) score showed good predictive accuracy for 5-day mortality (AUC: 0.839, 95% CI: 0.681-0.997), 6-week rebleeding (AUC: 0.797, 95% CI: 0.663-0.932), and 6-week mortality (AUC: 0.888, 95% CI: 0.797-0.979). CONCLUSIONS: Patients with cirrhosis with a high APRI and MELD-Na score were at high risk of early rebleeding and death after EGVB. Allocating appropriate monitoring and care for those patients is necessary.
RESUMO
BACKGROUND/AIM: The porous glass membrane pumping emulsification device enhances local therapeutic effects of transarterial chemoembolization for hepatocellular carcinoma (HCC); however, limited clinical outcomes have been reported. This study aimed to investigate the efficacy and safety of transarterial chemoembolization using the glass membrane pumping emulsification device for HCC. PATIENTS AND METHODS: Between 2019 and 2023, 58 patients (median age=73 years) with unresectable HCC underwent 73 transarterial chemoembolizations using the glass membrane pumping emulsification device at the Nagoya University Hospital. Treatment effects were assessed using contrast-enhanced computed tomography 1-3 months after therapy and every 2-3 months thereafter. RESULTS: The median size of treated tumors was 25.5 mm (45 solitary nodules). The median dosage of ethiodized oil mixed with the epirubicin solution was 3 ml. Complete and partial response were observed in 73% and 11% of patients, respectively. Local control rates at 6 and 12 months were 82.8% and 59.8%, respectively. The median time to recurrence after treatment was 581 days. No major treatment-related complications occurred. The number of tumors and therapeutic effects of the initial transarterial chemoembolization were significantly associated with better local control. CONCLUSION: The glass membrane pumping emulsification device facilitated the accumulation of more concentrated ethiodized oil within the tumor and effective local control.

BACKGROUND & AIMS: Steatotic liver disease (SLD) is often detected in health examinations. However, although individuals with metabolic dysfunction-associated SLD (MASLD) may have decreased bone mineral density (BMD), the specific risk factors remain unclarified. The objective of this study was to identify the factors associated with decreased BMD in patients with MASLD. METHODS: Individuals who underwent abdominal ultrasonography and BMD measurements at our healthcare center were included. The BMD of the calcaneus was assessed using an AOS-10SA bone densitometer. Decreased BMD was defined as a T-score below -1.0 SD or the administration of osteoporosis treatment. SLD was diagnosed based on specific ultrasonographic criteria. RESULTS: A total of 1410 patients were diagnosed with MASLD. The median age was 52 years. Multivariate analysis using a logistic regression model revealed that the independent predictors of decreased BMD were a low body mass index (BMI) or a small waist circumference (odds ratio (OR): 0.48, 95% confidence interval (CI): 0.34-0.67), hypertriglyceridemia (OR: 1.29, 95% CI: 1.00-1.65), and a weak grip strength (OR: 0.98, 95% CI: 0.97-1.00). Subgroup analyses of individuals aged 50 years or older, men, and individuals with a FIB-4 index of 1.3 or greater revealed that the absence of a high BMI or a large waist circumference was associated with decreased BMD. The subgroup analysis of men revealed that a weaker grip strength was associated with decreased BMD. CONCLUSION: The present study suggested several potential risk factors for decreased BMD in patients with MASLD. Individuals with the abovementioned risk factors should be encouraged to undergo BMD measurement from the perspective of preventive medicine.

BACKGROUND: Proteinuria is a common adverse event in systemic therapy for hepatocellular carcinoma (HCC). However, whether the presence of pretreatment proteinuria affects the clinical course is still unclear. METHOD: From 2011 to 2022, 321 patients with unresectable HCC who were treated with systemic therapy as first-line treatment were enrolled in this study. We retrospectively analyzed the presence of pretreatment proteinuria and the treatment course of systemic therapy. RESULTS: In the cohort, 190 patients were tested for proteinuria qualitatively within 3 months before systemic therapy; 75 were treated with sorafenib, 72 were treated with lenvatinib, and 43 were treated with atezolizumab plus bevacizumab. Overall survival tended to be longer for patients treated with lenvatinib and significantly longer with atezolizumab plus bevacizumab in patients without pretreatment proteinuria but not for those treated with sorafenib. Further analysis was performed in 111 patients treated with lenvatinib or atezolizumab plus bevacizumab who had proteinuria measured quantitatively. Multivariate analysis including proteinuria, liver function, and HCC stage revealed that the severity of proteinuria was an independent predictor of prognosis. CONCLUSION: Pretreatment proteinuria predicts a poorer prognosis in patients with unresectable HCC treated with lenvatinib or atezolizumab plus bevacizumab but not in those treated with sorafenib.
RESUMO
BACKGROUND: Combination therapy with anti-programmed death-ligand 1 and anti-vascular endothelial growth factor (VEGF) antibodies has become the standard treatment for un-resectable hepatocellular carcinoma (uHCC). We aimed to identify predictive circulating biomarkers for the outcome/response of the combination therapy in uHCC patients. METHODS: This prospective multicenter study enrolled 70 patients with uHCC who received atezolizumab and bevacizumab (Atez/Bev). We evaluated 47 circulating proteins in sera before and after 1 and 6 weeks of Atez/Bev therapy by multiplex bead-based immunoassay and ELISA. As controls, we analyzed the sera from 62 uHCC patients before treatment of lenvatinib (LEN) and healthy volunteers (HVs). RESULTS: The disease control rate was 77.1%. Median progression-free survival (PFS) was 5.7 months (95% confidence interval [CI] = 3.8-9.5). The pretreatment levels of osteopontin (OPN), angiopoietin-2, VEGF, S100-calcium-binding protein A8/S100-calcium-binding protein A9, soluble programmed cell death-1, soluble CD163, and 14 cytokines/chemokines were higher in patients with uHCC than in HVs. Among these, pretreatment OPN levels were higher in PD group than in non-PD group for Atez/Bev. The PD rate was higher in high OPN group than in low OPN group. Multivariate analysis identified high pretreatment OPN and high α-fetoprotein levels as independent predictors of PD. In the sub-analysis of Child-Pugh class A patients, PFS was also shorter in the high OPN group than in the low OPN group. Pretreatment OPN level was not associated with treatment response for LEN. CONCLUSION: High serum OPN levels were associated with poor response to Atez/Bev in patients with uHCC.

BACKGROUND: The clinical course of liver injury induced by immune checkpoint inhibitors (ICIs) varies among individuals, and there were few reports on the therapeutic effects of corticosteroids based on the patterns of liver injury. METHODS: We evaluated the characteristics and clinical course of immune-related liver injury in 1214 patients treated with ICIs for advanced malignancies except for hepatocellular carcinoma between August 2014 and May 2021. RESULTS: During the follow-up period (median, 252 days), 58 patients (4.8%) had an immune-related liver injury (≥ Grade 3). The liver-injury patterns were hepatocellular (n = 26, 44.8%), mixed (n = 11, 19.0%), or cholestatic (n = 21, 36.2%), and the median time to onset of liver injury was 39, 81, and 53 days, respectively; the hepatocellular pattern occurred earlier than the other types (p = 0.047). Corticosteroids were administered to 30 (51.7%) patients; while liver injury was improved in almost all patients with the hepatocellular pattern (n = 13/14, 92.9%), that failed to show improvement in over half of the patients with the non-hepatocellular patterns, and three patients with mixed patterns needed secondary immunosuppression with mycophenolate mofetil. Liver biopsies performed in 13 patients mainly showed lobular injury, endothelialitis, and spotty necrosis with infiltration of T cells positive for CD3 and CD8, but not CD4 or CD20. CONCLUSION: The incidence pattern and therapeutic response to corticosteroids in immune-related liver injury differ according to the injury type. Although corticosteroids were effective for the hepatocellular pattern, an additional strategy for refractory non-hepatocellular patterns is needed.
