Hidden in Plain Sight: A Case Series of Inflammatory Bowel Disease With Dermatologic Lesions As Initial or Concurrent Manifestations.

Pyoderma gangrenosum (PG) and erythema nodosum (EN) are rare skin conditions associated with inflammatory bowel disease (IBD), with increasing incidence as the disease progresses. We describe three cases of newly diagnosed IBD with cutaneous extraintestinal manifestations (EIMs) at the time of diagnosis. Three previously healthy patients presented with bloody diarrhea and concomitant nodular and ulcerating skin lesions at the onset of diarrhea. Dermatopathology showed PG and EN with endoscopic confirmation of ulcerative colitis. Clinical improvement was achieved with steroids and biological agents. These cases display the importance of a proper review of symptoms and a detailed workup of dermatological lesions prior to assuming infectious etiology.

Metastatic Signet Ring Cell Adenocarcinoma Manifesting as Chronic Leg Pain.

Signet ring cell carcinoma, a type of gastrointestinal system-related cancer, rarely metastasizes to the skeletal muscle. We present signet ring-cell carcinoma in a 28-year-old man who presented with left lower extremity pain and swelling. Imaging showed thickening of the distal esophagus, intestines, and bladder wall. Endoscopy revealed friable gastric mucosa and stenosis in the ascending colon, but biopsies were unrevealing. Leg muscle biopsy showed metastatic adenocarcinoma with focal signet ring features. Carcinoembryonic antigen and cancer antigen 19-9 were elevated. A gastrointestinal primary tumor was suspected. Our case urges clinicians to consider this rare cancer in patients presenting with skeletal muscle mass.

Seronegative Autoimmune Hepatitis: A Rare Manifestation of COVID-19.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus pandemic in 2019, commonly causes hepatic dysfunction. Liver injury ranges from mildly elevated liver enzymes to fulminant liver failure. Interestingly, there are cases that suggest a relationship between autoimmune hepatitis (AIH) in patients who either contracted coronavirus disease in 2019 (COVID-19) or were vaccinated against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We present a case of a 39-year-old female without a significant past medical history who presented with two weeks of jaundice, abdominal pain, nausea, and diarrhea. She had significantly elevated liver enzymes and conjugated hyperbilirubinemia. She also tested positive for SARS-CoV-2 but denied any respiratory symptoms; her vaccination status was up to date. She denied taking hepatotoxic agents, and the workup was negative for acute viral hepatitis. The F-actin antibody level was 22 units, but serum immunoglobulin (IgG), anti-nuclear (ANA), anti-smooth muscle, anti-mitochondrial, anti-liver/kidney microsomal-1, anti-soluble liver antigen, and anti-neutrophil cytoplasmic antibodies levels were not elevated. Computerized tomography of the abdomen and pelvis revealed hepatic hemangiomas. Eventually, a liver biopsy was performed, and histology showed active lymphoplasmacytic hepatitis with prominent regenerative changes and areas of confluent necrosis. The histologic findings, along with the patient's clinical course, were suggestive of autoimmune hepatitis. The patient was started on systemic steroids with an improvement of abdominal pain and jaundice, as well as an improvement of her liver chemical profile. She was discharged with plans for hepatology clinic follow-up. Here, we present a rare case of seronegative AIH in a patient with a recent COVID-19 infection and discuss the potential underlying mechanism. We call for further investigation into the relationship between autoimmune dysfunction and COVID-19, as well as the pathophysiology behind it. Analyzing how the virus causes autoimmune dysfunction may allow clinicians to more effectively treat patients suffering from sequelae of COVID-19 infection, and it is important not to exclude autoimmune hepatitis from the differential based on the initial autoimmune workup.

Glycogenic Hepatopathy as the Etiology of Abnormal Liver Chemistries in an Uncontrolled Type I Diabetic Patient.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in diabetics. However, it is not the sole cause of chronic liver disease in diabetics. We present a case of an 18-year-old male with poorly controlled type I diabetes mellitus who presented for evaluation of asymptomatic elevated liver chemistries. An extensive autoimmune, metabolic, and infectious workup was unrevealing. Liver biopsy was consistent with glycogenic hepatopathy without evidence of steatosis or fibrosis. Increased glycemic control led to his liver enzymes trending down. In conclusion, glycogenic hepatopathy should be considered in poorly controlled type 1 diabetics with elevated liver chemistries.

Restarting elective endoscopy safely amidst an evolving pandemic and the impact of patient perception.

BACKGROUND: The COVID-19 pandemic has led to disruptions in elective and outpatient procedures. Guidance from the Centers for Medicare and Medicaid Services provided a framework for gradual reopening of outpatient clinical operations. As the infrastructure to restart endoscopy has been more clearly described, patient concerns regarding viral transmission during the procedure have been identified. Moreover, the efficacy of the measures in preventing transmission have not been clearly delineated. METHODS: We identified patients with pandemic-related procedure cancellations from 3/16/2020 to 4/20/2020. Patients were stratified into tier groups (1-4) by urgency. Procedures were performed using our hospital risk mitigation strategies to minimize transmission risk. Patients who subsequently developed symptoms or tested for COVID-19 were recorded. RESULTS: Among patients requiring emergent procedures, 57.14% could be scheduled at their originally intended interval. COVID-19 concerns represented the most common rescheduling barrier. No patients who underwent post-procedure testing were positive for COVID-19. No cases of endoscopy staff transmission were identified. CONCLUSIONS: Non-COVID-19 related patient care during the pandemic is a challenging process that evolved with the spread of infection, requiring dynamic monitoring and protocol optimization. We describe our successful model for reopening endoscopy suites using a tier-based system for safe reintroduction of elective procedures while minimizing transmission to patients and staff. Important barriers included financial and transmission concerns that need to be addressed to enable the return to pre-pandemic utilization of elective endoscopic procedures.

Liver transplant recipient with respiratory failure due to pulmonary fibrosis related to telomere disease requiring lung transplantation.

Short telomere syndrome (STS) is characterized as multiorgan dysfunction presenting with unexplained cytopenias, cryptogenic cirrhosis and pulmonary fibrosis. We present a liver transplant recipient that gradually developed hypoxic respiratory failure attributed to idiopathic pulmonary fibrosis associated telomere disease that culminated in a successful single lung transplantation.

Two Cases of Bleeding Angiodysplasias Within Duodenal Diverticulum.

Although duodenal diverticula are relatively common, the bleeding complications from duodenal diverticula are exceedingly rare. We report 2 cases of obscure upper gastrointestinal bleeding secondary to angiodysplasias within a duodenal diverticula. These cases highlight the importance of considering duodenal diverticular angiodysplasias as a clinically significant etiology for upper gastrointestinal bleeding.

Direct-Acting Antiviral Treatment of Patients with Hepatitis C Resolves Serologic and Histopathologic Features of Autoimmune Hepatitis.

Patients with hepatitis C virus (HCV) often have elevated serum markers and histologic features of autoimmune hepatitis (AIH). We evaluated an HCV-positive (HCV+) study group that had elevated serum markers of AIH before starting direct-acting antiviral (DAA) therapy (n = 21) and compared them to an HCV+ control group that did not have laboratory studies suggesting AIH (n = 21). Several patients in the study (17/21) and control (11/21) groups had liver biopsies before DAA treatment, and many were biopsied due to elevated serum markers of AIH. Evaluation of pre-DAA treatment liver biopsies showed histologic features suggestive of AIH in 64.7% (11/17) of the study group and 45.5% (5/11) of the control group. Patients who were HCV+ with elevated serum markers of AIH had significantly increased hepatitis activity (P < 0.001) and slightly increased fibrosis stages (P = 0.039) in their pretreatment liver biopsies compared to controls. We hypothesized that the elevated serum markers and histologic features of AIH would resolve following DAA treatment. Serum markers of AIH in the study group began decreasing by 6 months posttreatment, and 52.4% (11/21) had complete resolution. Alanine aminotransferase levels significantly decreased into the normal range for all patients (21/21). Even patients that had persistence of serum markers of AIH after DAA treatment had normal transaminases. Six patients from the study patient group and 4 patients from the control group had follow-up liver biopsies after DAA treatment, and all biopsies showed resolution of the histologic features of AIH. Conclusion: The majority of HCV+ patients that have serum markers and/or histopathologic features of AIH should initially be treated with DAA.

Evaluation and management of variceal bleeding.

Acute variceal bleeding is one of the most fatal complications of cirrhosis and is responsible for about one-third of cirrhosis-related deaths. Therefore, every effort should be made to emergently resuscitate the patients, start pharmacotherapy as soon as possible and do endoscopic therapy in a timely manner. Despite the recent advances in treatment, mortality rate is still high. We provide a comprehensive review of evaluation and management of variceal bleeding.
