Statin prescribing patterns in patient-centered medical home patients with NAFLD.

OBJECTIVES: Cardiovascular disease is the leading cause of mortality in patients with nonalcoholic fatty liver disease (NAFLD), and statins play a pivotal role in the primary prevention of cardiovascular events. This study investigates statin prescribing in primary care patients with NAFLD to identify opportunities to address cardiovascular disease risk in this cohort. STUDY DESIGN: Retrospective cohort study of primary care electronic health record data from 2012-2018. METHODS: This cohort included 652 patients with radiographic evidence of hepatic steatosis and no evidence of competing chronic liver disease. A statin prescription identified at any time during the study period was the primary outcome. Univariate and multivariable analyses were performed to evaluate the association of clinical signals and comorbidities with statin prescribing. RESULTS: Of the 652 patients in the NAFLD cohort, 56% received a statin prescription during the study period. Elevations in aminotransferases were not associated with statin prescribing (adjusted odds ratio [AOR], 1.17; 95% CI, 0.78-1.76), whereas older patients (AOR, 1.06; 95% CI, 1.05-1.08) and those with diabetes (AOR, 2.61; 95% CI, 1.73-3.92), hypertension (AOR, 2.76; 95% CI, 1.70-4.48), and a BMI greater than or equal to 30 kg/m2 (AOR, 1.49; 95% CI, 1.01-2.22) had higher odds of having a statin prescribed. Of the 288 patients without a statin prescription, 49% had an indication for statin therapy by atherosclerotic cardiovascular disease risk. In total, 16% of included patients did not have lipid panel results during the study period. CONCLUSIONS: This study showed no association between NAFLD and statin prescribing, and the findings highlight opportunities to improve primary prevention of cardiovascular disease in these at-risk patients.

Identifying Patients at Risk for Fibrosis in a Primary Care NAFLD Cohort.

GOALS AND BACKGROUND: Using natural language processing to create a nonalcoholic fatty liver disease (NAFLD) cohort in primary care, we assessed advanced fibrosis risk with the Fibrosis-4 Index (FIB-4) and NAFLD Fibrosis Score (NFS) and evaluated risk score agreement. MATERIALS AND METHODS: In this retrospective study of adults with radiographic evidence of hepatic steatosis, we calculated patient-level FIB-4 and NFS scores and categorized them by fibrosis risk. Risk category and risk score agreement was analyzed using weighted κ, Pearson correlation, and Bland-Altman analysis. A multinomial logistic regression model evaluated associations between clinical variables and discrepant FIB-4 and NFS results. RESULTS: Of the 767 patient cohorts, 71% had a FIB-4 or NFS score in the indeterminate-risk or high-risk category for fibrosis. Risk categories disagreed in 43%, and scores would have resulted in different clinical decisions in 30% of the sample. The weighted κ statistic for risk category agreement was 0.41 [95% confidence interval (CI): 0.36-0.46] and the Pearson correlation coefficient for log FIB-4 and NFS was 0.66 (95% CI: 0.62-0.70). The multinomial logistic regression analysis identified black race (odds ratio=2.64, 95% CI: 1.84-3.78) and hemoglobin A1c (odds ratio=1.37, 95% CI: 1.23-1.52) with higher odds of having an NFS risk category exceeding FIB-4. CONCLUSIONS: In a primary care NAFLD cohort, many patients had elevated FIB-4 and NFS risk scores and these risk categories were often in disagreement. The choice between FIB-4 and NFS for fibrosis risk assessment can impact clinical decision-making and may contribute to disparities of care.

Fever Through a Jaundiced Eye.

Pyogenic liver abscess (PLA) is an important clinical entity to consider in a patient with fever and abdominal pain. Previously, the condition was difficult to diagnose and treat, but with the introduction of widely available and reliable imaging techniques, its diagnosis has become more straightforward. Although uncommon, PLA should especially be considered in the differential diagnosis for patients with specific predisposing conditions such as underlying biliary tract disease, whether as a result of chronic inflammatory disease or malignancy. The introduction of percutaneous drainage has revolutionized the management of PLA, and thus, this disease has become largely correctable.

Ischemic Hepatitis as the Presenting Manifestation of Cardiac Amyloidosis.

An abrupt elevation in aminotransferases without clear etiology may be attributed to hypoxic hepatitis. Underlying cardiac dysfunction, an important clinical clue, is often overlooked as a cause of hypoxic hepatitis, and understanding the interdependence of the heart and liver is crucial in making this diagnosis. Causes of cardiac dysfunction may include any of many different diagnoses; infiltrative heart disease is a rare cause of cardiac dysfunction, with amyloidosis being the most common among this category of pathologies. More advanced imaging techniques have improved the ability to diagnose infiltrative heart disease, thus allowing quicker diagnosis of conditions such as amyloidosis.
