Hepatology consultation is associated with decreased early return to alcohol use after discharge from an inpatient alcohol use disorder treatment program.

BACKGROUND: Alcohol cessation is the only intervention that both prevents and halts the progressions of alcohol-associated liver disease. The aim of this study was to assess the relationship between a return to alcohol use and consultation with hepatology in treatment-seeking patients with alcohol use disorder (AUD). METHODS: Two hundred forty-two patients with AUD were enrolled in an inpatient treatment program, with hepatology consultation provided for 143 (59%) patients at the request of the primary team. Patients not seen by hepatology served as controls. The primary outcome was any alcohol use after discharge assessed using AUDIT-C at 26 weeks after discharge. RESULTS: For the primary endpoint, AUDIT at week 26, 61% of the hepatology group and 28% of the controls completed the questionnaire (p=0.07). For the secondary endpoint at week 52, these numbers were 22% and 11% (p = 0.6). At week 26, 39 (45%) patients in the hepatology group versus 31 (70%) controls (p = 0.006) returned to alcohol use. Patients evaluated by hepatology had decreased rates of hazardous alcohol use compared to controls, with 36 (41%) versus 29 (66%) (p = 0.008) of the patients, respectively, reporting hazardous use. There were no significant differences in baseline characteristics between groups and no difference in rates of prescribing AUD therapy. There was no difference in outcomes at 52 weeks. CONCLUSIONS: Patients evaluated by hepatology had significantly lower rates of return to alcohol use and lower rates of hazardous drinking at 26 weeks but not at 52 weeks. These findings suggest that hepatology evaluation during inpatient treatment of AUD may lead to decreased rates of early return to alcohol use.

Gastrointestinal Computed Tomography Findings in Chronic Granulomatous Disease with Subgroup Clinicopathologic Analysis.

BACKGROUND: Chronic granulomatous disease (CGD) is a rare primary immunodeficiency which can lead to gastrointestinal (GI) complications including inflammatory bowel disease. Radiographic findings in this cohort have not been well described. AIMS: To describe the frequency and spectrum of gastrointestinal abnormalities seen on computed tomography (CT) in patients with CGD and determine whether radiography was predictive of endoscopic or histopathologic inflammatory findings. METHODS: A retrospective review was conducted on 141 consecutive CGD patients seen at the National Institutes of Health between 1988 and 2011. All corresponding CTs were reviewed for gastrointestinal abnormalities including wall thickening. Endoscopic and histopathologic findings were reviewed in subjects with documented endoscopy within 30 days of an imaging study. Findings were compared between patients with and without wall thickening on CT to determine whether bowel wall thickening was predictive of endoscopic or histologic inflammatory findings. RESULTS: Two hundred and ninety-two CTs were reviewed. GI wall thickening was present on CT in 61% of patients (n = 86). Among a subgroup of 20 patients who underwent endoscopy at the time of their imaging, there was a statistically significant correlation between radiographic gastrointestinal wall thickening and endoscopic inflammation in the same intestinal segment (p = 0.035). Additionally, there was a significant correlation between radiographic gastrointestinal wall thickening and inflammatory features on histopathology (p = 0.02). CONCLUSIONS: GI abnormalities are commonly observed on CT in CGD patients. Bowel wall thickening correlates with endoscopic and histopathologic evidence of inflammation. These findings may be used to better facilitate directed endoscopic assessment and histopathologic sampling in patients with CGD.

Fecal Incontinence in Inflammatory Bowel Disease.

BACKGROUND: Fecal incontinence (FI) is frequently reported in inflammatory bowel disease (IBD). METHODS: We retrospectively reviewed data from the Study of a Prospective Adult Research Cohort with IBD registry. RESULTS: Three hundred forty-seven patients had Crohn disease and 145 had ulcerative colitis. 14.2% of patients reported FI. FI was associated with active disease. FI was not associated with disease location, phenotype, or perianal involvement. Greater than 50 years of age or 15 years of disease increased the odds of FI and remission decreased the odds of FI. CONCLUSIONS: Further research into the mechanism of FI in IBD is needed.

Blistering autoimmune skin reaction following SHINGRIX vaccination in an ulcerative colitis patient: Case report and literature review.

Patients with inflammatory bowel disease, especially those on immunosuppressive therapy, are at higher risk of acquiring infectious diseases (Reich et al., 2016). For this reason, immunizations are routinely recommended in comprehensive inflammatory bowel disease care. SHINGRIX, a non-live recombinant herpes zoster vaccine, was approved by the Food and Drug Administration in 2017. Adults aged 50 and over are recommended to receive two doses of SHINGRIX. Unlike ZOSTAVAX® which is a live zoster vaccine that has been in use since 2006, SHINGRIX is safe for those on immunosuppression (Reich et al., 2016). The offside effects of SHINGRIX include injection-site erythema, tenderness, fatigue, and gastrointestinal upset. To our knowledge, blistering autoimmune skin disorders following SHINGRIX administration have not been reported. Here we discuss a case of a 74-year-old female patient with a history of ulcerative proctosigmoiditis on mesalamine who presented with a blistering skin disease after each SHINGRIX vaccination.

Twitter As a Noninvasive Bio-Marker for Trends in Liver Disease.

With the success of hepatitis C virus (HCV) direct-acting antiviral therapies, there has been a shift in research focus to the other major chronic liver diseases (CLDs). The use of social media, specifically Twitter, has become a popular platform for understanding public health trends and for performing health care research. To evaluate this, we studied the areas of public interest and social media trends of the following three major CLDs: hepatitis B virus (HBV), HCV, and nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH). Twitter activity data from January 1, 2013, through January 1, 2019, for HBV, HCV, and NAFLD/NASH were collected using the social media analytic tool Symplur Signals (Symplur LLC) software. Content and regression analyses were performed to understand and predict Twitter activity for each of the CLDs. Over the study period, there were 810,980 tweets generating 4,452,939,516 impressions. HCV tweet activity peaked in 2015 at 243,261 tweets, followed by a decline of 52.4% from 2015 to 2016 with a subsequent plateau through 2018. Meanwhile, NAFLD/NASH and HBV tweet activity has continued to increase, with projections that these two CLDs will surpass HCV by the second half of 2023 and 2024, respectively. Treatment and Management was the most popular content category for HCV and NAFLD/NASH, while Prevention was the most popular content category for HBV. Conclusion: Twitter is a useful social media tool to gauge public interest in liver disease over time. The information provided by Twitter can be used to identify gaps in public knowledge or highlight areas of interest that may need further research. Future studies on the use of Twitter in liver disease are warranted.

Asparaginase-induced hepatotoxicity: rapid development of cholestasis and hepatic steatosis.

BACKGROUND: L-Asparaginase is a bacterial enzyme used in the treatment of acute lymphoblastic leukemia. In the ongoing U.S. Drug-Induced Liver Injury Network (DILIN) prospective study, standard and pegylated asparaginase were the most frequent cause of liver injury with jaundice among anti-cancer agents (8 of 40: 20%). The unique features of this hepatotoxicity are described. METHODS: Eight cases from 5 DILIN centers were reviewed for clinical course, laboratory values, imaging, and histopathology. RESULTS: Seven females, aged 29-59 years, and one 8-year-old boy, all with leukemia, developed jaundice within 9-21 days (median 15 days) of starting asparaginase or pegaspargase, during the first (n = 6) or second (n = 2) cycle. Prominent symptoms were jaundice (n = 8), fatigue (6), abdominal pain (6) but rarely pruritus (1). Initial median ALT level was 284 U/L (range 83-1076), Alk P 159 U/L (64-452), and bilirubin 4.4 mg/dL (3.7-8.4). Bilirubin levels rose thereafter in all patients to median peak of 17.5 mg/dL (11.7-25.7), INR rose to 1.1-1.7 and serum albumin fell to 1.5-2.6 g/dL. Hepatic imaging revealed fatty liver in all patients. Liver biopsy showed steatosis but minimal hepatocyte necrosis. One patient restarted on pegaspargase re-developed less severe injury. CONCLUSION: Asparaginase is a common cause of antineoplastic-induced liver injury with jaundice, typically with short latency, marked steatosis, and prolonged jaundice, which can lead to delays in antileukemic therapy. The cause of injury is likely direct inhibition of hepatic protein synthesis caused by asparagine depletion.

Liver disease in patients with cystic fibrosis.

PURPOSE OF REVIEW: The aim of this study was to provide an overview of the current understanding of the pathophysiology, diagnosis and management of cystic fibrosis-liver disease (CFLD). RECENT FINDINGS: CFLD has a variety of manifestations. Previously, it was thought that patients progressed from mild cholestatic disease to cirrhosis to decompensated cirrhosis with portal hypertension. Newer evidence suggests that some patients may develop cirrhosis while others develop noncirrhotic portal hypertension. Advances in our understanding of the pathophysiology of disease necessitate modifications to the current diagnostic criteria. Both fibroscan and noninvasive biomarkers can be used to identify patients with cirrhosis and portal hypertension. Ursodeoxycholic acid remains the mainstay of therapy despite a paucity of rigorous studies supporting its use. Novel therapeutic agents such as CF transmembrane conductance regulator (CFTR) modulators and potentiators are encouraging but need to be evaluated specifically in CFLD. SUMMARY: A better understanding of the pathophysiology of disease is critical to developing more disease-specific diagnostics and therapeutics.

The Changing Paradigm of Management of Liver Abscesses in Chronic Granulomatous Disease.

Background: Chronic granulomatous disease (CGD) is a rare genetic disorder causing recurrent infections. More than one-quarter of patients develop hepatic abscesses and liver dysfunction. Recent reports suggest that disease-modifying treatment with corticosteroids is effective for these abscesses. Comparison of corticosteroid therapy to traditional invasive treatments has not been performed. Methods: Records of 268 patients with CGD treated at the National Institutes of Health from 1980 to 2014 were reviewed. Patients with liver involvement and complete records were included. We recorded residual reactive oxygen intermediate (ROI) production by neutrophils, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase germline mutation status, laboratory values, imaging characteristics, time to repeat hepatic interventions, and overall survival among 3 treatment cohorts: open liver surgery (OS), percutaneous liver-directed interventional radiology therapy (IR), and high-dose corticosteroid management (CM). Results: Eighty-eight of 268 patients with CGD suffered liver involvement. Twenty-six patients with a median follow-up of 15.5 years (8.5-32.9 years of follow-up) had complete records and underwent 100 standard interventions (42 IR and 58 OS). Eight patients received a treatment with high-dose corticosteroids only. There were no differences in NADPH genotype, size, or number of abscesses between patients treated with OS, IR, or CM. Time to repeat intervention was extended in OS compared with IR (18.8 vs 9.5 months, P = .04) and further increased in CM alone (median time to recurrence not met). Impaired macrophage and neutrophil function measured by ROI production correlated with shorter time to repeat intervention (r = 0.6, P = .0019). Conclusions: Treatment of CGD-associated liver abscesses with corticosteroids was associated with fewer subsequent hepatic interventions and improved outcome compared to invasive treatments.

Gastrointestinal Features of Chronic Granulomatous Disease Found During Endoscopy.

BACKGROUND & AIMS: Chronic granulomatous disease (CGD) is an inherited disorder of the reduced nicotinamide adenine dinucleotide phosphate oxidase complex within phagocytic cells that predisposes people to bacterial and fungal infections. Approximately 40% of patients with CGD have gastrointestinal involvement. We aimed to characterize the endoscopic features of gastrointestinal CGD and define the role of endoscopy in patients. METHODS: We created a database of all patients with CGD seen at the National Institutes of Health from 1990 through 2010. We identified patients who had an endoscopy, and collected information from those with CGD-associated inflammatory bowel disease. We analyzed clinical data (demographic information and symptoms), endoscopic data (indication, preparation quality, degree of inflammation, mucosal findings, and complications), and pathologic data. RESULTS: A total of 211 endoscopies (96 esophagogastroduodenoscopies, 82 colonoscopies, and 33 flexible sigmoidoscopies) were performed at the National Institutes of Health on 78 patients with CGD. Esophageal, gastric, and duodenal inflammation were detected in 21%, 74%, and 37% of patients, respectively. Esophageal dysmotility and structural abnormalities were noted in 26%. Of the patients who had colonic CGD-inflammatory bowel disease, 74% had skip lesions and 93% had anorectal disease. Enteric fistulae were found in 18% of patients; 73% of these were perianal. Colonic strictures were observed in 24% of patients; 80% were in the anorectal area. CONCLUSIONS: Based on an analysis of clinical and endoscopic data from 78 patients, CGD-inflammatory bowel disease is a distinct entity, primarily involving the anus and rectum, with skip lesions in the remaining bowel. Bowel strictures and fistulae are present in a significant number of patients. Upper gastrointestinal tract inflammatory disease is common, although typically not as severe as colonic disease. Upper and lower endoscopies are important in characterizing the gastrointestinal features of CGD.

Features of Patients With Crohn's Disease and Hidradenitis Suppurativa.

BACKGROUND & AIMS: There have been reports of an association between Crohn's disease and hidradenitis suppurativa, a chronic, relapsing, inflammatory condition of the skin. We investigated features of hidradenitis suppurativa in patients with Crohn's disease by analyzing clinical data and performing a literature review. METHODS: We performed a retrospective study by using information from the Mount Sinai Medical Center database from 2003 through 2013; International Classification of Diseases, 9th Revision codes were used to identify patients who had both Crohn's disease and hidradenitis suppurativa. We identified a total of 18 patients with inflammatory bowel disease (15 with Crohn's disease, 3 with ulcerative colitis) and hidradenitis suppurativa. We also performed a systematic search for publications listed in PubMed through December 2013. RESULTS: We identified 15 patients with Crohn's disease and hidradenitis suppurativa who met the inclusion criteria (11 women, 4 men). Nine patients were black, 5 were white, and 1 was Asian. Regions most affected by hidradenitis suppurativa included the axilla (53%), inguinal region (47%), and perianal region (73%). Seven patients had colonic Crohn's disease, and 8 had ileocolonic Crohn's disease; 10 patients had perianal disease. Fourteen patients received medical treatment for hidradenitis suppurativa and for Crohn's disease. Twelve patients were treated with tumor necrosis factor inhibitors for Crohn's disease (11 received infliximab and 4 received adalimumab). Nine patients required dose escalation; 11 responded to tumor necrosis factor inhibitors, and 8 required surgery. Four patients were treated with tumor necrosis factor inhibitors for hidradenitis suppurativa (all with infliximab). Three required a dose escalation; 4 responded to tumor necrosis factor inhibitors, and 3 required surgery. CONCLUSIONS: Crohn's disease and hidradenitis suppurativa are severe inflammatory conditions that can develop in the same patient. They frequently require increased medical and surgical therapy.

Gastrointestinal histopathology in chronic granulomatous disease: a study of 87 patients.

Gastrointestinal (GI) involvement in chronic granulomatous disease (CGD), a rare genetic immunodeficiency, mimics other inflammatory bowel diseases. We report GI pathology from 87 CGD patients seen at the NIH Clinical Center, with vague to severe clinical symptoms, in whom biopsies (313) had been evaluated (esophagus [23], stomach [71], small bowel [52] including duodenum [39], ileum [12], and jejunum [1], and colon [167]). Additionally reviewed was GI tissue from 15 autopsies. In our patient cohort, the mean age was 22 years (age range, 3 to 44 y; 2:1 male to female ratio). There were pathologic changes in 83/87 (95%) patients; with colon being the most commonly involved site and esophagus the least. There were microgranulomas in 53/87 (61%), pigmented macrophages in 64/87 (74%), tissue eosinophilia in 31/87 (36%), and chronic and/or acute inflammation in 57/87 (66%) patients. A subset of patients had villous shortening in the duodenum (8/39) and ileum (5/12). We identify microgranulomas in 76/167 (46%) colon, 12/52 (23%) small bowel, and 4/71 (6%) gastric biopsies; pigmented macrophages in 109/167 (65%) colon and 7/52 (13%) small bowel biopsies and 14/15 autopsies; chronic and/or acute inflammation in 97/167 (58%) colon, 13/52 (25%) small bowel, 42/71 (59%) gastric, and 5/23 (22%) esophageal biopsies; tissue eosinophilia in 43/167 (26%) colon, 7/52 (13%) small bowel, and 2/71 (3%) gastric biopsies. Only 4/87 (5%) patients had normal histology. No infectious etiology was identified in the majority of inflammatory lesions. We found that mild to severe GI pathology was common in CGD. In addition, microgranulomas, pigmented macrophages, and eosinophilia are not associated with acute (neutrophilic) inflammation.

The role of surgery in the management of patients with refractory chronic granulomatous disease colitis.

BACKGROUND: Chronic granulomatous disease is a rare immunodeficiency complicated by dysregulated inflammation and granulomatous complications of the GI tract. The management of chronic granulomatous disease colitis presents the dilemma of an immunocompromised host requiring immunosuppressive therapy which can potentiate fatal infections. OBJECTIVE: The aim of this study was to identify the types of GI surgery performed in patients and determine the role of surgery in the management of refractory colitis. DESIGN AND SETTINGS: A retrospective single-institution chart review was performed. PATIENTS: Of 268 patients with chronic granulomatous disease treated at the National Institutes of Health between 1985 and 2011, 98 (37%) were identified as having colitis; 27 (10%) had a history of GI luminal surgery. MAIN OUTCOME MEASURES: Patient characteristics, type of GI surgery, and clinical outcomes were documented. RESULTS: A total of 62 GI luminal surgeries were performed in 27 patients with chronic granulomatous disease and colitis. All 27 had a history of perineal disease requiring intervention. Four (15%) had additional surgery performed for reasons other than colitis. Otherwise, 12 (44%) had surgery limited to the perineum, 2 (7%) had a segmental resection, and 13 (48%) underwent fecal diversion with ileostomy or colostomy. Despite local procedures, 7 (58%) patients in the perineal-only group remained symptomatic. Both patients with a segmental resection had persistent perineal disease, and 1 had a recurrent colovesicular fistula. Of the 13 ostomy patients, 11 initially received a diverting ostomy. Eight (73%) of these ultimately required additional procedures for refractory disease, and 4 (36%) developed peristomal pyoderma gangrenosum. Four patients who underwent proctocolectomy with end ileostomy, either initially (2) or as a definitive procedure (2), experienced resolution of colitis and perineal disease. LIMITATIONS: This study is limited by its retrospective design, small sample size, and highly selected patient population. CONCLUSIONS: Proctocolectomy with end ileostomy may offer a definitive treatment in a patient with refractory chronic granulomatous disease colitis given current therapeutic limitations.
