Association of statins with nonalcoholic fatty liver disease in patients with diabetes.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in patients with diabetes; limited data suggested that statins may reduce the risk of NAFLD progression. This study aimed to examine the association between statins and the development or progression of NAFLD in veterans with diabetes. In a new-user negative control design, we conducted a retrospective propensity score (PS)-matched cohort study of patients with diabetes between 2003 and 2015. After excluding patients with other causes of liver disease, we formed PS using 85 characteristics. The primary outcome was a composite NAFLD progression outcome. Primary analysis examined odds of outcome in PS-matched cohort. Post-hoc analysis included a PS-matched cohort of statin users with intensive lowering of low-density lipoprotein-cholesterol (LDL-C) vs low-intensity lowering. We matched 34,102 pairs from 300,739 statin users and 38,038 non-users. The composite outcome occurred in 8.8% of statin users and 8.6% of non-users (odds ratio (OR) 1.02, 95% confidence interval (95% CI) 0.97-1.08). In the post-hoc analysis, intensive lowering of LDL-C compared to low-intensity showed increased NAFLD progression (OR 1.21, 95% CI 1.13-1.30). This study showed that statin use in patients with diabetes was not associated with decreased or increased risk of NAFLD progression. Intensive LDL-C lowering, compared to low-intensity LDL-C lowering, was associated with an increased risk of NAFLD progression.

Herpes Simplex Virus Esophagitis in an Immunocompetent Patient.

Esophagitis due to herpes simplex virus (HSV) infection is a rare entity in the immunocompetent population. It is usually seen in immunocompromised hosts, those with human immunodeficiency virus (HIV) infection, malignancies, and patients on immunosuppressive medications. We present a case of a young immunocompetent man with anabolic steroid use who presented with esophagitis symptoms found to be from HSV infection. So far, the use of corticosteroids has been reported as a predisposing factor for HSV esophagitis in immunocompetent hosts in multiple case reports. However, our case suspects that transient immunosuppression with similar medication can cause HSV esophagitis in otherwise immunocompetent hosts.

Esophageal Granular Cell Tumor: An Uncommon Cause of Dysphagia.

Granular cell tumors (GCTs) are rare, typically benign, solitary neoplasms that can arise throughout the body, with reports of cases in the tongue, esophagus, colon, skin, vulva, and skeletal muscle, among others. Although GCTs are usually asymptomatic, esophageal GCTs can grow large enough to cause dysphagia. When developing the differential diagnosis for dysphagia, a broad consideration includes routine etiologies such as esophageal strictures, eosinophilic esophagitis, carcinoma, webs and rings, achalasia, and motility disorders, but GCTs may not readily come to mind. Due to their scarcity, this case report is presented to raise awareness of esophageal GCTs and emphasize key goals for diagnosing and managing this uncommon yet treatable cause of dysphagia. This case report details the clinical course of a patient presenting with a chief complaint of difficulty swallowing that was found to be caused by a subepithelial esophageal tumor discovered with esophagogastroduodenoscopy (EGD) and endoscopic ultrasound (EUS). Histopathological studies paired with immunohistochemical investigations of a tissue biopsy confirmed the etiology of the offending esophageal mass to be a GCT. The patient's dysphagia resolved after endoscopic mucosal resection of the GCT, and follow-up evaluations have remained negative for recurrence. This case highlights the esophageal GCT as an uncommon source of dysphagia and the need for EGD and EUS evaluations of subepithelial esophageal lesions accompanied by histopathological analysis for a definitive diagnosis of GCT.

Recent advances in understanding and managing acute pancreatitis.

This review highlights advances made in recent years in the diagnosis and management of acute pancreatitis (AP). We focus on epidemiological, clinical, and management aspects of AP. Additionally, we discuss the role of using risk stratification tools to guide clinical decision making. The majority of patients suffer from mild AP, and only a subset develop moderately severe AP, defined as a pancreatic local complication, or severe AP, defined as persistent organ failure. In mild AP, management typically involves diagnostic evaluation and supportive care resulting usually in a short hospital length of stay (LOS). In severe AP, a multidisciplinary approach is warranted to minimize morbidity and mortality over the course of a protracted hospital LOS. Based on evidence from guideline recommendations, we discuss five treatment interventions, including intravenous fluid resuscitation, feeding, prophylactic antibiotics, probiotics, and timing of endoscopic retrograde cholangiopancreatography (ERCP) in acute biliary pancreatitis. This review also highlights the importance of preventive interventions to reduce hospital readmission or prevent pancreatitis, including alcohol and smoking cessation, same-admission cholecystectomy for acute biliary pancreatitis, and chemoprevention and fluid administration for post-ERCP pancreatitis. Our review aims to consolidate guideline recommendations and high-quality studies published in recent years to guide the management of AP and highlight areas in need of research.

Concurrent radiotherapy with Carboplatin and cetuximab for the treatment of medically compromised patients with locoregionally advanced head and neck squamous cell carcinoma.

BACKGROUND: Cetuximab (Cx) + radiation therapy (RT) is well-tolerated and has improved survival in patients (pts) with locoregionally advanced head and neck squamous cell carcinomas (LA-HNSCC). However, its efficacy when compared to HD-DDP + RT has been questioned. At our institution, low-dose weekly carboplatin is added to Cx + RT for patients unsuitable for HD-DDP. METHODS: We reviewed records of 16 patients with LA-HNSCC treated with definitive Cx + carboplatin + RT at the University of Miami from 2007 to 2011. Median follow-up was 24 months (range: 1-69 months). RESULTS: Median age: 71.5 years (range: 57-90 years); 15 male, 1 female. ECOG PS 0 = 15, 1 = 1. TNM staging was: T 1 = 1, T 2 = 5, T 3 = 8, T 4 = 2; N stage: N 0 = 8, N 1 = 5, N 2a = 2, N 2b = 1. All patients received weekly carboplatin (AUC 1.5-2), Cx given conventionally and daily conventionally fractionated RT. Median total weeks of concurrent systemic therapy = 7 (range: 3-8 weeks). RT was delivered to a median total dose of 70 Gy (range 30-74 Gy). Of the 15 evaluable patients, there were: 12 CR, 2 PR, and 1 PD. There were three local in-field failures, two regional failures, and three distant failures. At last follow-up, 8/15 patients remained with NED. Three-year locoregional recurrence was 28.3% (95% CI: 7.7-53.9%). Mean percentage of weight loss was 14% (range: 6-26%). Two patients required systemic therapy dose reduction. Three patients experienced a treatment delay and three did not finish RT as planned including a patient who received only 30 Gy due to death secondary to MI during treatment. CONCLUSION: In this small retrospective series, carboplatin/Cx/RT was well-tolerated and efficacious in patients unsuitable for HD-DDP having LA-HNSCC. Acute toxicities were similar to Cx + RT, likely due to the non-overlapping toxicity profiles of the two systemic agents. We hypothesize that the addition of a well-tolerated cytotoxic chemotherapy agent may improve the therapeutic ratio of Cx + RT in patients who are poor candidates for more aggressive therapies and warrants evaluation in a prospective manner.

Predictive factors for clinically actionable computed tomography findings in inflammatory bowel disease patients seen in the emergency department with acute gastrointestinal symptoms.

BACKGROUND: The wide use of abdomino-pelvic computed tomography (APCT) in emergency departments (ED) has raised the concern for radiation exposure, costs and potential reactions to contrast agents. The aim of this study was to determine the yield and predictive factors for clinically actionable findings (CAF) in APCTs performed in patients with inflammatory bowel disease (IBD) who visit the ED. METHODS: We performed a cross-sectional study including patients with IBD who visited the ED. Variables considered were demographics, IBD phenotype, clinical symptoms, IBD medication use prior to ED visit, laboratory values, and imaging results. The primary outcome was a composite of CAF, defined as new, intra-abdominal abscess or tumor, bowel obstruction, fistulae, diverticulitis, choledocholithiasis, or appendicitis. RESULTS: 354 patients were included. One or more CAF were reported in 26.6% of the APCTs (32.1% in CD and 12.8% in UC [p<0.01]). Independent predictive variables of CAF in CD were: CRP level ≥5mg/dl (p=0.04), previous history of IBD surgery (p=0.037), Black race (p<0.01) and low body mass index (p<0.01). None of the study variables predicted CAF in UC. CONCLUSIONS: The yield for CAF with APCT in the ED was high for CD patients but minimal for those with UC and was not improved by the use of contrast. Elevated CRP, low BMI, Black race and previous history of IBD surgery predicted CAF in CD but no variables were predictive of CAF in UC.

Hispanics with primary biliary cirrhosis are more likely to have features of autoimmune hepatitis and reduced response to ursodeoxycholic acid than non-Hispanics.

BACKGROUND & AIMS: Primary biliary cirrhosis (PBC) is a cholestatic disease that predominantly affects middle-aged Caucasian women. Studies have suggested that PBC has a more aggressive course in individuals of Hispanic ancestry. We investigated the clinical presentation and progression of PBC in an ethnically diverse population. METHODS: We performed a cross-sectional study, analyzing data from Hispanic (n = 70) and non-Hispanic patients (n = 134) with PBC seen at the University of Miami/Jackson Memorial Hospital from January 1, 2000, through December 31, 2011. We compared demographics, clinical presentation, response to therapy, and outcomes between the groups. RESULTS: Age at diagnosis, antimitochondrial antibody positivity, frequency of advanced histologic stage, use and dose of ursodeoxycholic acid (UDCA), and the presence of pruritus or fatigue were similar between groups. Hypothyroidism was less frequent among Hispanics (16% vs 29% in non-Hispanics; P = .04). Hispanic subjects were more likely to have overlap syndrome of PBC and autoimmune hepatitis than non-Hispanics (31% vs 13%; P = .002). After a median follow-up period of 3.65 years, a greater percentage of Hispanics had ascites (24% vs 12%; P = .03) and variceal bleeding (20% vs 7%; P = .01), although there were no differences in the number of deaths or liver transplants. Of 204 total patients, 180 received UDCA for at least 1 year. A lower proportion of Hispanic patients had a biochemical response to treatment (60% vs 88%; P < .0001). Independent predictors of poor biochemical response were younger age at diagnosis and Hispanic ethnicity. CONCLUSIONS: In a cross-sectional study, patients of Hispanic ethnicity with PBC had an increased prevalence of overlap syndrome, reduced response to UDCA treatment, and more frequent complications of portal hypertension than non-Hispanic patients.
