Impact of Gastroenterology Consultation on the Clinical Outcomes of Patients Admitted With Hepatic Encephalopathy.

Introduction Hepatic encephalopathy (HE) is a common complication of cirrhosis and a common reason for hospital admission. We aimed to determine whether expert consultation from gastroenterology (GI) leads to better clinical outcomes for inpatients with HE. Methods A retrospective review was performed of all adult patients (age ≥ 18) admitted with HE to a tertiary care hospital between January 2013 and April 2018. Patients who received a GI consult were compared to patients who did not receive a GI consult (No consult group). The primary outcome was hospital length of stay (LOS); secondary outcomes were rates of 30-day hospital readmission and 90-day mortality. Multivariate analysis was conducted to adjust for known confounders.  Results Four hundred and twenty-five patients (814 encounters) were included in the study; of these, 236 patients had received a GI consultation for HE. Patients in the GI consult group were younger (mean age 55 vs 58 years, p= 0.02) and had higher Model For End-Stage Liver Disease-sodium (MELD-Na) score (mean MELD-Na 23.5 vs 17.5, p<0.01) compared to patients who did not receive GI consultation. The precipitants of HE were significantly different between the groups: there was more spontaneous bacterial peritonitis (SBP) and GI bleeding (GIB) in the GI consult group and more lactulose non-adherence in the no consult group. There was no difference in the etiology of liver disease between the two groups. Median LOS for the GI consult group was six days vs three days in the no consult group (p<0.01); the incidence rate ratio was 1.79 (95%CI 1.59-2.02, p<0.01) on multivariate analysis. There was no difference in 30-day readmission or 90-day mortality between the two groups.  Conclusion GI consultation for patients with HE admitted to a hospital medicine service may be associated with longer LOS. In selected patients admitted with HE, GI consultation may not be necessary to achieve good clinical outcomes.

Viral Hepatitis Among African Immigrants with Hepatocellular Carcinoma in Minnesota: High Prevalence Yet Low Awareness.

We aimed to study the virologic profile of immigrants from Africa with viral hepatitis-related hepatocellular carcinoma (HCC) who received care at our institution. We conducted a descriptive study among African-born patients with HCC who received care at University of Minnesota Medical Center from 2011 to 2018. We analyzed the prevalence, virologic profiles and treatment of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections prior to HCC diagnosis. 74 African-born patients with HCC were eligible for analysis. 54 had HCV and 20 had HBV infection. 80% of HBV patients were treated but remained with inadequate viral suppression at the time of HCC diagnosis while only 39% of HCV patients were treated prior to HCC diagnosis. Lost to follow up was common in both groups. Our findings suggest that there is a significant gap in appropriate viral hepatitis care in an African immigrant population in Minnesota. Culturally-appropriate strategies are needed to bridge this gap.

Unexpected clinical outcomes following the implementation of a standardised order set for hepatic encephalopathy.

OBJECTIVE: We evaluated the effect on clinical outcomes of implementing a standardised inpatient order set for patients admitted with hepatic encephalopathy (HE). METHODS: A retrospective review of patients with cirrhosis admitted with HE. Hospital admissions for HE for which the electronic health record (EHR) order set was used were compared with admissions where the order set was not used. Primary outcome was length of hospital stay (LOS). Secondary outcomes were 30-day readmissions, in-hospital complications, in-hospital and 90-day mortality. RESULTS: There were 341 patients with 980 admissions over the study period: 263 patients with 736 admissions where the order set was implemented, and 78 patients with 244 admissions where the order set was not implemented. Median LOS was 4 days (IQR 3-8) in the order set group compared with 3 days (IQR 2-7) (p<0.001); incidence rate ratio 1.37 (95% CI 1.20 to 1.57), p<0.001. 30-day readmissions rate was 56% in the order set group compared with 40%, p=0.01; OR for readmission was 1.88 (95% CI 1.04 to 3.43), p=0.04. Hypokalaemia occurred in 46% of admissions with order set use compared with 36%, when the order set was not used; p=0.003, OR 1.72 (95% CI 1.22 to 2.43), p=0.002. No significant differences were seen for in-hospital mortality and 90-day mortality. CONCLUSION: Implementation of an inpatient EHR order set for use in patients with HE was associated with unexpected clinical outcomes including increased LOS and readmissions. The convenience and advantages of standardisation of patient care should be balanced with a degree of individualisation, particularly in the care of medically complex patients. Furthermore, standardised processes should be evaluated frequently after implementation to assess for unintended consequences.

Pulmonary Mycobacterium Spindle Cell Pseudotumor in Patient With Liver Transplant.

We report a case of liver transplant patient who presented with lung masses, found to be Mycobacterium spindle cell pseudotumors. The masses demonstrated hypermetabolic activities on positron emission tomography. Core biopsy revealed sheets of spindle histiocytic cells with abundant acid-fast bacilli identified as Mycobacterium avium-intracellulare complex. This finding is a rare presentation of Mycobacterium infection, mainly nontuberculous Mycobaterium. It is characterized by a benign, spindle cell mass-forming reaction. Most of the reported cases had acquired immune deficiency syndrome or organ transplant. Histopathology illustrating the proliferation of spindle cell shaped histiocytes containing numerous acid-fast bacilli is the gold standard for diagnosis. The standard treatment has not been well established; previously reported cases followed the standard treatment for Mycobacterium based on organ involvement. Our case is the first case to our knowledge that reports pulmonary Mycobacterium spindle cell pseudotumors in a liver transplant recipient.

A new era of gene editing for the treatment of human diseases.

The treatment of human diseases using gene-editing technology has been envisioned for several decades with the realisation that so many were associated with mutations in DNA. The Human Genome Project opened new doors for identifying the genetic bases for human suffering. Research on gene editing has been active since the 1970s, but the technology has seen substantial growth and application just within the past decade. Simply stated, CRISPR technology has become a phenomenon in both biomedical and therapeutics research. Concurrently, cell therapies and pluripotent stem cell research have also been refined and now interfaced with CRISPR technology to enhance and maximise their potential in modelling as well as treatment of human diseases. In this review, we discuss the novel and revolutionary modality of gene editing, as this marks a new era in research and medicine. We also discuss gene-modifying technologies leading to CRISPR, as they are still being used for a wide variety of genomic applications. The modes and challenges for delivery of gene editing components are also discussed. Lastly, we review examples of human diseases that are not only amenable to gene editing techniques, but also show true promise of cure in the early 21st century of genetic correction and gene repair.

Direct-acting antiviral regimens are safe and effective in the treatment of hepatitis C in simultaneous liver-kidney transplant recipients.

Hepatitis C (HCV) remains the single most common etiology of end-stage liver disease leading to simultaneous liver/kidney transplant (SLKT) and has worse post-transplant survival compared to non-HCV patients. We aim to assess the effectiveness and tolerance of the all-oral direct-acting antiviral (DAA) agents with or without ribavirin (RBV) in the treatment of HCV recurrence post-SLKT. Thirty-four patients were studied retrospectively, composed predominantly of treatment-naïve (73.5%) non-Caucasian (61.8%) males (82.4%) infected with genotype 1a (64.7%). 94.1% reached a sustained virologic response (SVR) after 24 weeks (32/34 patients), without difference between 12 and 24 weeks of therapy. 64.7% had no clinical side effects. Three deaths occurred, all unrelated to treatment. One patient had liver rejection; tacrolimus was increased and prednisone was initiated while HCV treatment was continued and the patient ultimately achieved SVR. No liver graft losses. No kidney rejection or losses. We demonstrated that DAA combinations with or without RBV result in a remarkable SVR rate and tolerated in the majority of the studied SLKT patients. It is safe to wait to treat until post-kidney transplant and therefore increase the donor pool for these patients. Our cohort is ethnically diverse, making our results generalizable.
