OBJECTIVES: Low-dose interleukin 2 (Ld-IL2) is increasingly being explored as an immune-modulating treatment for autoimmune diseases which mainly affect T cell subsets. This study investigates the metabolic effects of Ld-IL2 therapy in patients with primary Sjögren's syndrome (pSS).
METHOD: A total of 60 patients were recruited to conduct a double-blind, randomized clinical trial. Of these patients, 50% (30/60) received Ld-IL2 therapy along with standard treatment for 12 weeks, followed by 12 weeks of follow-up. The effectiveness was evaluated by Sjögren's Tool for Assessing Response (STAR). An untargeted analysis was performed to profile hydrophilic metabolites.
RESULTS: Metabolic profiling revealed significant alterations post-treatment, notably in metabolites like acetyl-CoA, ascorbic acid, and glutathione, which are beneficial in managing autoimmune diseases. In addition, the levels of metabolite accumulation were correlated with variations in immune cell subsets (p < 0.05), particularly Tregs. Moreover, patients exhibiting a specific metabolic profile, including lower serum levels of isoleucine, ADP, Thymidine 5'-triphosphate, and other metabolites, had a high response rate (91.7%-98.6%), as indicated by the receiver operating characteristic (ROC) curve.
CONCLUSIONS: These findings suggest that Ld-IL2 therapy influences metabolic pathways in pSS, offering insights into the systemic effects of Ld-IL2 therapy beyond immune modulation.
TRIAL REGISTRATION NUMBER: ClinicalTrials.gov number, NCT02464319. Key Points • Metabolic alteration in pSS is significantly associated with Ld-IL2 therapy. • Metabolic changes correlate with variations in immune cell subsets, particularly Tregs. • Metabolic profiling could be a valuable tool in guiding Ld-IL2 therapy choices for pSS patients.
