Background/Purpose:
Peripheral ulcerative keratitis (PUK) is a severe inflammation of the outer portions of the cornea that may lead to perforation. It may be associated to rheumatic diseases. The treatment is based on systemic corticoisteroids and conventional immunosuppressive drugs. In refractory cases biological therapy may be needed. Our aim was to compare anti-TNFα vs Rituximab (RTX) in refractory PUK.
Methods:
Multicenter study of 24 patients with PUK. All of them presented inadequate response to corticosteroids and at least 1 systemic traditional immunosuppressive drug.
Anti-TNFα were used in 17 patients: Adalimumab (n=9) 40 mg/sc every 1-2 weeks, infliximab (IFX) (n=7) 3-5 mg/kg iv/4-6 weeks, etanercept (n=1) 50 mg/week. RTX was used in 7 patients 1-2 g i.v. every 6 or 12 months.
The main outcomes were Best Corrected Visual Acuity (BCVA), signs of inflammation (scleritis and episcleritis), progression to corneal thinning, central keratolysis and ocular perforation.
Comparisons were made between baseline and 1st month, 6th month and 1st year (STATISTICA, StatSoft Inc. Tulsa, Oklahoma, USA). Quantitative variables were expressed as mean±SD or median [IQR], accordingly to its distribution. They were compared with the Student t or the Mann-Whitney U test respectively. Dichotomous variables were expressed as percentages and compared by the chi-square test.
Results:
We studied 24 patients/32 affected eyes. The underlying diseases in the anti-TNFα group were Rheumatoid Arthritis (RA) (n=14), Psoriasic Arthritis (n=2) and Behçet Disease (n=1); and in the RTX group: RA (n=5), granulomatous polyangiitis (n=1) and microscopic polyangiitis (n=1).
At baseline there were no significant differences between both groups in general features or in ocular involvement (TABLE). Before biological therapy they had received the following systemic drugs (anti-TNFα vs RTX) i.v. metilprednisolone (2 vs 4), doxycycline (7 vs 1), ascorbic acid (2 vs 0), MTX (11 vs 4), AZA (1 vs 2) and others (7 vs 3). In addition, 10 patients, in both groups, had to be undergoing to surgery: amniotic membrane (n=5), penetrating keratoplasty (n=2), conjunctival resection (n=2), tissue adhesives (n=2), conjunctival flap (n=1) and lamellar keratoplasty (n=1).
Once the treatment was iniciated the ocular evolution was similar (TABLE).
After a men follow-up of 22.53±22.60 (anti-TNFα) and 22.28±8.28 months with RTX the following severe side effects were observed: supraventricular tachycardia (n=1) with RTX and pulmonary Tuberculosis (n=1) with IFX.
Conclusion:
In this study, anti-TNFα therapy and RTX seem to be equally effective for the treatment of peripheral ulcerative keratits associated to rheumatic diseases refractory to conventional treatment.
