From the Guidelines
The assessment and plan for this 45-year-old male with mildly elevated liver enzymes (AST 65, ALT 78) appears accurate and appropriate, given the patient's elevated BMI of 29.5, history of hyperlipidemia, and absence of other obvious causes, and is supported by recent evidence from the field of gastroenterology 1. The physician has correctly identified mild transaminitis and reasonably suspects nonalcoholic fatty liver disease (NAFLD) as the most likely cause. Key points to consider in this case include:
- The patient's limited alcohol intake, lack of symptoms, and absence of risk factors for viral hepatitis support this assessment.
- The plan includes appropriate next steps: ordering a hepatic ultrasound to confirm steatosis, viral hepatitis panel to rule out viral causes, repeating liver function tests in 3 months for monitoring, and lifestyle modifications including weight loss and minimizing alcohol.
- The physician is also appropriately monitoring the patient's statin therapy, as atorvastatin can occasionally cause elevated liver enzymes, though this is less common than NAFLD in this clinical scenario, as noted in recent guidelines for the management of non-alcoholic fatty liver disease 1.
- The CPT code 99214 seems reasonable for an established patient visit of moderate complexity involving multiple diagnostic possibilities, ordering of tests, and counseling on management strategies.
- Recent studies have highlighted the importance of early identification and management of NAFLD, given its association with increased risk of liver-related complications, including cirrhosis, hepatocellular carcinoma, and liver-related mortality, as well as cardiovascular disease 1. Overall, this represents a thorough and evidence-based approach to evaluating and managing mild transaminitis in a middle-aged patient with metabolic risk factors.
From the Research
Assessment of the Patient's Condition
- The patient, B.R., is a 45-year-old male with elevated liver enzymes (AST 65, ALT 78) discovered during routine bloodwork.
- He has a history of hyperlipidemia and is taking atorvastatin 40 mg daily.
- The patient's symptoms and physical exam are unremarkable, with no jaundice, abdominal pain, nausea, dark urine, or pruritus.
- The patient's BMI is 29.5, which is considered overweight.
Likely Diagnosis and Treatment
- The patient's elevated liver enzymes and BMI suggest a likely diagnosis of nonalcoholic fatty liver disease (NAFLD) 2.
- The treatment plan includes counseling for weight loss, minimizing alcohol intake, and monitoring statin therapy.
- A hepatic ultrasound has been ordered to assess for steatosis, and repeat LFTs are scheduled for 3 months.
- The use of statins, such as atorvastatin, may have a beneficial effect on NAFLD, as they have been shown to improve serum aminotransferase levels and ultrasound findings 3, 4.
- One study found that atorvastatin combined with vitamins C and E significantly reduced the odds of NAFLD at the end of follow-up 5.
Risk Factors and Associations
- The patient's hyperlipidemia and overweight status are risk factors for NAFLD 2, 6.
- The patient's use of atorvastatin may have a beneficial effect on his cardiovascular risk factors, which are commonly associated with NAFLD 3, 4.
- The patient's lack of significant alcohol use, IV drug use, tattoos, or transfusions reduces the likelihood of other liver diseases, such as viral hepatitis.
