To the Editor Sacks and colleagues1 report an excellent case of severe hypertriglyceridemia-associated pancreatitis depicting the progressive hepatotoxic consequences of long-term lomitapide use. Although the authors portray a comprehensive case, there are several aspects that warrant additional clarification. First, though the authors clearly explain the significant deterioration to steatohepatitis and fibrosis with elevated alkaline phosphatase levels over time, there is no mention of the forthcoming therapeutic plan. Because current Food and Drug Administration labeling for lomitapide recommends discontinuing use in patients with this presentation type, should consideration of cessation of therapy be realized? Furthermore, despite observations of worsening liver disease, no discussion exists as to why lomitapide therapy was continued for 13 years, rather than considering other modalities such as use of apheresis alone or in combination. In addition, because hepatic steatosis greater than 5% will develop in 78% of those who use lomitapide, other treatment options (eg, apheresis) should be regarded in case adverse effects support discontinuing lomitapide therapy.
