Isolated hepatic sarcoidosis: A case series.

Sarcoidosis is a multi-organ inflammatory disease that can have hepatic involvement in up to 80% of cases. Rarely, sarcoidosis can manifest with only confined disease to the liver. While most patients with hepatic sarcoidosis are clinically silent, certain cases can have insidious onset leading to cirrhosis and secondary complications. Here, we describe three cases of isolated hepatic sarcoidosis to illustrate the range of presentations that may be associated with this condition. Clinicians should be vigilant in consideration of hepatic sarcoidosis as a culprit when investigating patients with undifferentiated liver disease.

A Pilot Study to Evaluate a New Hep-GRP Care Pathway to Improve Outcomes Among Canadian Older Adults with Liver Cirrhosis.

Background: Older adults with cirrhosis have complex medical needs that are not satisfied by organ specific management. Interdisciplinary approach may mitigate comorbidity and improve patient satisfaction. Methods: A pilot study consisted of dual specialist interdisciplinary referral pathway and mixed virtual care delivery model are prospectively evaluated in older adults (65 years and older) with cirrhosis during the COVID-19 pandemic between September and December 2022. Participant attitudes towards telemedicine were surveyed. Results: 68 participants with cirrhosis were consecutively assessed by hepatology. The mean age was 73 years. 39 (57%) screened positive for one or more geriatric syndrome(s). Comprehensive geriatric assessments were conducted via telemedicine in 18 participants, with additional referrals to physiotherapy and nutritional education. Compared to a historic cohort matched for age, sex, and Child-Pugh class, acute health service utilization measured by ER visits among those received dual specialist interdisciplinary consultation were lowered by 1.11 per patient at three-month follow up period (p = .0006, 95% CI 0.47-1.74). Majority participants (87.6%) preferred telemedicine or mixed method visits. Conclusion: An interdisciplinary approach to older adults with cirrhosis will likely be beneficial, and routine screening for geriatric syndrome may lead to reduced acute health-care utilization in the short term. Telemedicine and virtual screening tools in seniors should be fully explored to improve access to care.

The feasibility and acceptability of an online mind-body wellness program for patients with primary biliary cholangitis.

Background: Persons with primary biliary cholangitis (PBC) experience significantly higher rates of mental distress and impaired health related quality of life (HrQoL) than the general population. Given limited evidence, but a high need, our primary aim was to assess feasibility and acceptability of a 12-week, online, mind-body wellness program in people with PBC. Methods: This was a single-group, sequential mixed-methods, pre-post feasibility, and acceptability study. Core program components included follow-along movement, meditation and breathwork videos, and cognitive behavioural therapy informed activities. This was supplemented by weekly phone check-ins. Feasibility was assessed by recruitment, adherence, and retention. The pre-post exploratory efficacy assessment included surveys for fatigue, perceived stress, anxiety, depression, HrQoL, and resilience. A qualitative descriptive approach with semi-structured interviews evaluated study experiences. Results: Thirty-two participants were recruited within 30 days and 29 (91%) were retained to end-of-study. Of these, 25 (86%) adhered to carrying out the mind-body practice at least 2-3 days per week. Feedback supported acceptability (satisfaction score 90%). Significant improvements were observed in fatigue (13%, p = 0.004), anxiety (30%, p = 0.005), depression (28%, p = 0.004), and five PBC-40 domains (itch, fatigue, cognitive, emotional, general symptoms). Qualitative interviews revealed improved stress management, better coping, and a more positive mindset. Fatigue and self-sabotaging thoughts were cited as barriers to participation. Conclusions: These findings suggest that a 12-week online mind-body intervention is feasible and acceptable in patients with PBC. After iterative refinement, a randomized controlled trial will be designed using this feedback.

Grayken lessons: between a rock and a hard place? A 37-year-old man with acute liver injury while enrolled in a managed alcohol program for severe alcohol use disorder.

Managed alcohol programs aim to reduce health and social harms associated with severe alcohol use disorder. Here, we describe a young man with severe alcohol use disorder enrolled in a managed alcohol program, who was admitted to hospital with acute liver injury. Fearing that alcohol was contributing, the inpatient care team discontinued the managed alcohol dose in hospital. He was ultimately diagnosed with cephalexin-induced liver injury. After consideration of risks, benefits, and alternative options, the patient and care team jointly decided to restart managed alcohol after hospital discharge. With this case, we describe managed alcohol programs and summarize the emerging evidence-base, including eligibility criteria and outcome measures; we explore clinical and ethical dilemmas in caring for patients with liver disease within managed alcohol programs; and we emphasize principles of harm reduction and patient-centered care when establishing treatment plans for patients with severe alcohol use disorder and unstable housing.

Late presentation of posterior reversible encephalopathy syndrome following liver transplantation in the setting of tacrolimus and cannabis use.

A 45-year-old female presented to hospital with confusion and visual disturbances. She had undergone a liver transplant 3 years prior for cirrhosis secondary to primary biliary cholangitis. Computed tomography and magnetic resonance imaging of the brain showed features consistent with posterior reversible encephalopathy syndrome. Her medications included tacrolimus, sirolimus, and prednisone. She reported smoking 4 grams of cannabis per day. Following cessation of tacrolimus, the patient's encephalopathy and visual disturbances resolved. To our knowledge, this case represents the longest time elapsed from liver transplantation to the development of tacrolimus-associated posterior reversible encephalopathy syndrome in the literature. This case highlights the potential danger of cannabis use in transplant recipients who are on immunosuppressants such as tacrolimus. Clinicians should have a high index of suspicion for posterior reversible encephalopathy syndrome in post-transplant patients presenting with altered mental status, even years after liver transplantation, and be familiar with potential interactions between cannabis and immunosuppressants.

Liver biopsy complication rates in patients with non-alcoholic fatty liver disease.

BACKGROUND: With new treatments for non-alcoholic fatty liver disease (NAFLD) on the horizon, it will be important to risk-stratify patients based on degree of fibrosis to allocate treatment to those at highest risk. No studies have examined the complication rates of liver biopsies in patients with NAFLD in the outpatient setting. METHODS: We conducted a retrospective chart review of all outpatient elective liver biopsies for NAFLD at a tertiary care centre over a 10-year period. Demographic variables and stage of fibrosis were recorded. Complications up to 1 week post-procedure were recorded. We used univariate logistic regression models to estimate the odds of major complications by fibrosis stage, age, sex, platelets, and international normalized ratio (INR). RESULTS: There were 582 biopsies reviewed in total. The mean age was 53 years. There was an even proportion of males to females. The mean fibrosis stage was 1.9; platelet count was 223.9, INR was 1, and partial thromboplastin time (PTT) was 31. Major complications occurred in 8 out of 582 biopsies (1.4%). Bleeding accounted for 6 of the major complications observed, while infection and pneumoperitoneum each occurred once. There were no statistically significant associations between age (odds ratio [OR] 0.97, 95% CI 0.92-1.03), female sex (OR 1.00, 95% CI 0.25-4.04), platelet count <150 (OR 0.59, 95% CI [-inf.], 3.86), INR >1.3 (OR 0.47, 95% CI 0.057-3.85), fibrosis stage, and complication rate. CONCLUSIONS: Our results are consistent with previous studies examining complication rates in other patient populations and clinical settings and support the overall safety of liver biopsies.

Prospective Evaluation of Virtual MR Elastography With Diffusion-Weighted Imaging in Subjects With Nonalcoholic Fatty Liver Disease.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is increasingly common worldwide and can lead to the development of cirrhosis, liver failure and cancer. Virtual magnetic resonance elastography (VMRE), which is based on a shifted apparent diffusion coefficient (sADC), is a potential noninvasive method to assess liver fibrosis without the specialized hardware and expertise required to implement traditional MR elastography (MRE). Although hepatic steatosis is known to confound ADC measurements, previous studies using VMRE have not corrected for hepatic fat fraction. PURPOSE: To compare VMRE, corrected for the confounding effects of unsuppressed fat signal, to MRE and biopsy in subjects with suspected NAFLD. STUDY TYPE: Prospective, cross-sectional. POPULATION: A total of 49 adult subjects with suspected NAFLD (18 male; median age 55 years, range 33-74 years) who underwent liver biopsy. FIELD STRENGTH/SEQUENCE: 3T, diffusion-weighted spin echo planar, chemical-shift encoded (IDEAL IQ) and MRE sequences. ASSESSMENT: Two observers drew regions of interest on sADC, proton density fat fraction and MRE-derived stiffness maps. Fat-corrected sADC values were used to calculate the diffusion-based shear modulus according to the VMRE method. Predicted fibrosis stage for MRE and VMRE was determined using previously published cut-off values. STATISTICAL TESTS: The relationship between VMRE and MRE was assessed with least-squares linear regression (coefficient of determination, R2 ). Agreement between MRE and VMRE-predicted fibrosis stage was evaluated with a kappa coefficient and accuracy compared using McNemar's test. A one-way ANOVA determined if the fat-corrected sADC (VMRE) and MRE differed by fibrosis stage. A P value < 0.05 was considered statistically significant. RESULTS: Least squares regression of VMRE vs. MRE revealed R2  = 0.046 and a slope that was not significantly different from zero (P = 0.14). There was no agreement between MRE and VMRE-predicted fibrosis stage (kappa = -0.01). The proportion of correctly predicted fibrosis stage was significantly higher for MRE compared to VMRE. MRE was significantly associated with fibrosis stage, but fat-corrected sADC was not (P = 0.24). DATA CONCLUSION: Fat-corrected VMRE was not associated with fibrosis stage in NAFLD. Further investigation is required if VMRE is to be considered in subjects with NAFLD. EVIDENCE LEVEL: 1 TECHNICAL EFFICACY: Stage 2.
