In addition, triglycerides are often significantly elevated in patients with HLH because elevated TNF-α inhibits lipoprotein lipase [34], whereas triglycerides are not or only moderately elevated (>2.0 mmol/L) in infected patients [35], hence, elevated triglyceride levels can strengthen the suspicion of HLH in adults. The gene discussed is LPL; the disease is hemophagocytic syndrome.
