Increased risk of hypereosinophilia following initiation of glucagon-like peptide 1 receptor agonist: A symmetry analysis using the Danish health registries
Glucagon-like peptide 1 receptor agonists (GLP1-RA) are increasingly used in the treatment of Type 2 diabetes and as antiobesity drugs. Cases of hypereosinophilic syndrome (HES) following initiation of GLP1-RA have been reported [1]. HES is defined by eosinophil counts of 1.5 × 109/L or greater and related end-organ damage [2]. Because these events are too rare to be detected in randomized controlled trials, we aimed to quantify the association between GLP1-RA initiation and incident hypereosinophilia (HE) using real-world data.
Leveraging nationwide Danish prescription [3] and laboratory data [4], we conducted a sequence symmetry analysis (SSA) investigating the occurrence of HE following initiation of GLP1-RA and for comparison sodium–glucose co-transporter 2 inhibitors (SGLT2i) and dipeptidyl peptidase 4 inhibitors (DPP4i) [5].
The SSA compares the occurrence of HE during a symmetric time window before and after initiation of the drug of interest. If there is no association between drug initiation and HE, we would expect HE to occur equally often during both windows. However, if GLP1-RA use increases eosinophil counts, we would expect HE to occur more frequently after initiation. The sequence ratio (SR) is calculated as the number of HE events after drug initiation divided by the number of HE events before drug initiation and corresponds to the incidence rate ratio obtained in the corresponding cohort study [6]. If the rate of HE is increased after initiation of GLP1-RA compared to the period before initiation, we would expect an SR above 1.
We identified all individuals who initiated a GLP1-RA, SGLT2i or DPP4i (Appendix) between 1 June 2015 and 31 May 2024 and obtained eosinophil counts of 1.5 × 109/L or greater within the last 180 days before the drug initiation, or within the first 180 days after. Observed SRs were adjusted for temporal trends in HE [5]. In subgroup analyses, we evaluated semaglutide and other GLP1-RAs separately, as well as Ozempic and Wegovy. For sensitivity analyses, we calculated SRs for observation windows of 90 and 365 days and with mild (≥0.5–1.5 × 109/L) and massive eosinophilia (≥5 × 109/L) as outcomes. Finally, we used a thrombocyte count below 50 × 109/L as a negative control outcome.
The study was approved by the institutional data protection board at the University of Southern Denmark and the Danish Health Data Authority (Project number FSEID-00006047). Ethical approval is not needed in Denmark for studies based purely on registry data.
We identified 213,521 individuals who initiated a GLP1-RA among whom 245 had HE within 1 year of drug initiation. The median age was 54 years (interquartile range [IQR] 42–63), 49% were female and median year of initiation of GLP1-RA was 2022 (IQR 2021–2023). Of these, 193 individuals had HE after drug initiation, and 52 individuals had HE before drug initiation, yielding an SR of 3.83 (95% confidence interval [CI] 2.84–5.24). Among initiators of SGLT2i and DPP4i, we found SRs of 0.76 (N = 108/146, CI 0.59–0.97) and 0.89 (N = 68/76, CI 0.64–1.23).
In subgroup analyses, SRs for semaglutide, other GLP1-RAs, Wegovy and Ozempic were similar to results for all GLP1-RAs combined (Fig. 1). The outcome mild eosinophilia yielded an SR of 1.08 for GLP1-RA initiators (N = 1207/1136, CI 1.0–1.18). For massive eosinophilia, we observed 13 events after GLP1-RA initiation and less than 5 events before initiation. Analyses with shorter and longer observation windows yielded elevated SRs (SR 3.87, CI 2.62–5.85 and 2.50 [1.97–3.18]). For the negative-control outcomes, we found for GLP1-RA, SGLT2i and DPP4i, respectively, SRs of 1.64 (N = 44/27, CI 1.02–2.66), SR of 1.28 (N = 118/93, CI 0.98–1.68) and SR of 0.84 (N = 75/89, CI 0.62–1.15) after initiation. Fig. S1 shows a steep increase in HE during the first 3 months after GLP1-RA initiation, which was not observed for SGLT2i or DPP4i initiators.
In this nationwide study, we found that HE is three times more likely to occur after initiation of GLP1-RAs compared to the period prior to initiation. This finding was specific to GLP1-RAs and not observed for other antidiabetic drugs. Albeit the negative control outcome generated a result that was non-null for GLP1-RAs, results for the negative control outcome were much closer to 1.0 compared to the main analysis and were compatible with the results for SGLT2i. Thus, our study provides evidence of a temporal association between the initiation of GLP1-RAs and HE. The main limitation of our study is that the outcome was biochemically defined HE and not end-organ damage due to HE. Another important limitation is that the study population only included individuals who initiated GLP1-RA and had an eosinophil count measured. Larger studies are needed to quantify the potential association between GLP1-RAs and clinically manifest HES.
