BACKGROUND: Lipodystrophy encompasses a group of rare disorders associated with severe metabolic disease. These disorders are defined by abnormal fat distribution, with near-total (generalized lipodystrophy, GL) or partial (partial lipodystrophy, PL; i.e. familial partial lipodystrophy, FPLD) absence of adipocyte mass leading to a decreased ability to store lipids safely. Excess lipids are more likely to be stored in non-adipose tissues, which leads to the metabolic manifestations. We have recently shown that glucagon-like peptide-1 agonists are associated with metabolic improvements in FPLD. We hypothesized that tirzepatide, a dual incretin, may also lead to metabolic improvement in patients with lipodystrophy.
METHODS: Observational cohort of patients with PL or GL who received tirzepatide clinically were tracked in the context of ongoing natural history studies.
RESULTS: Seventeen patients received tirzepatide, 14 with FPLD (ages within 30-74 years; 12 female 2 male). After a median 8.7 months of follow-up, BMI (medianΔ -1.7; range -5.9 to 0.9 kg/m 2 ; p =0.008), HbA1c (medianΔ -1.1%; range -6.3 to -0.1%; p <0.001), triglycerides [medianΔ - 65 mg/dL (-0.73 mmol/L); range -3820 to 43 mg/dL (-43.2 to 0.49 mmol/L); p =0.003] and total daily insulin requirements (medianΔ -109; range -315 to 0 units/day; p =0.002) were significantly reduced. Three patients with acquired GL (Ages within 35-64 years; all female) also demonstrated a robust response to tirzepatide with reduced BMI (22.2->20.9; 26.2->25.4; 19.5->17.6 kg/m 2 ), HbA1c (8.5%->7.0%; 10.2%->7.8%; 9.1%->6.5%), triglycerides (91->80; 641->293; 1238->100 mg/dL or 1.03->0.90; 7.24->3.31; 14.0->1.13 mmol/L), and total daily insulin requirement (85->0; 0->0; 1000->750 units/day). Three patients did not tolerate dose escalation due to gastroesophageal reflux.
CONCLUSIONS: Tirzepatide may be an effective treatment for patients with lipodystrophy.
