TOPLINE:
Men with immunoglobulin G4 (IgG4)-related disease exhibit significantly lower serum lipase levels and a greater likelihood of organ involvement than women, highlighting significant sex-dependent differences in disease manifestations.
METHODOLOGY:
- Researchers conducted a retrospective study of 328 patients (69% men) diagnosed with IgG4-related disease at the Massachusetts General Hospital – Rheumatology Clinic, Boston, who met the American College of Rheumatology–European Alliance of Associations for Rheumatology (ACR-EULAR) classification criteria between January 2008 and May 2023.
- Among the 328 patients, 69% were men and 31% were women, with a significant male-to-female ratio of 2.2:1.0. Men were typically older at diagnosis (median age, 63.7 vs 58.2 years).
- Data on serum lipase levels, renal involvement, and other clinical and laboratory parameters were collected.
TAKEAWAY:
- Men had higher baseline ACR-EULAR scores, indicating more severe disease (median score of 35.0 vs 29.5; P = .0010).
- Male patients demonstrated a median baseline serum lipase concentration of 24.5 U/L, significantly lower than the 33.5 U/L observed in women.
- Pancreatic (50% vs 26%) or renal (36% vs 18%) involvement was more common in men.
- Men exhibited higher IgG4 levels (P = .0050) and active B-cell responses in the blood (P = .0095).
IN PRACTICE:
According to the authors, this work confirms “the impression of an important sex disparity among patients with IgG4-related disease, with most patients being male, and male patients demonstrating strong tendencies toward more severe disease than female patients.”
SOURCE:
The study was led by Isha Jha, MD, Massachusetts General Hospital, Boston. It was published online on May 30, 2024, in The Lancet Rheumatology.
LIMITATIONS:
The study’s retrospective design may limit the ability to establish causality between sex differences and IgG4-related disease manifestations. A relatively small percentage of patients were assessed before receiving any immunosuppressive treatment, potentially influencing the observed clinical parameters.
DISCLOSURES:
This work was supported by the National Institutes of Health/National Institute of Allergy and Infectious Diseases, the Rheumatology Research Foundation, and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Some authors declared financial ties outside this work.
This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.
