Early immunosuppressive therapy may reduce recurrence of RA associated peripheral ulcerative keratitis
Early immunosuppressive therapy initiation reduces inflammation and recurrence of RA-associated peripheral ulcerative keratitis (PUK) suggests a new study published in the British Journal of Ophthalmology
The study was done to evaluate the role of early immunosuppressive therapy (IMT) in the management of rheumatoid arthritis (RA)-associated peripheral ulcerative keratitis (PUK).
Single-centre, retrospective, comparative cohort study. Patients with RA-associated PUK were divided into two groups; those exposed to and those not exposed to early IMT, defined as administrating therapy within the first 4 weeks from the PUK onset. Outcomes included PUK recurrence, control of inflammation and development of ocular complications, including corneal scarring and perforation, cataract formation or progression and permanent visual loss.
Results
A total of 52 eyes from 36 patients were included for analysis; 37 (71.2%) eyes received early IMT and 15 (28.8%) eyes did not. Follow-up time was 41.2+53.3 months (range: 4–236 months). While early IMT was a protective factor (HR 0.345, 95% CI 0.126 to 0.946, p=0.039), late RA diagnosis after PUK onset (HR 4.93, 95% CI 1.75 to 13.85, p=0.002) and retarded (≥2 months) control of inflammation (HR 8.37, 95% CI 1.88 to 37.16, p=0.005) were risk factors for PUK recurrence. Late IMT (OR 7.75, 95% CI 2.00 to 29.99, p=0.003), an unknown diagnosis of RA at first visit (OR 4.14, 95% CI 1.15 to 14.91, p=0.030) and at least one PUK recurrence (OR 6.42, 95% CI 1.71 to 24.07, p=0.006) were risk factors for visual loss. Survival analysis rendered eyes exposed to early IMT a lower risk of PUK recurrence (p=0.039).
Eyes with RA-associated peripheral ulcerative keratitis (PUK) exposed to early IMT were more likely to achieve earlier inflammatory control, fewer recurrences and had better visual outcomes.
