tacrolimus and Chorioretinitis

Evaluation of the use of tacrolimus in the treatment of birdshot retinochoroiditis (BRC) at a tertiary referral centre with the aim to describe its safety and efficacy.. The medical records of 25 patients diagnosed with BRC at uveitis service, Moorfields Eye Hospital, and who had received tacrolimus treatment were retrospectively reviewed. The main outcome measures of the study were (1) safety of tacrolimus in terms of side effects and (2) efficacy, as measured both by control of inflammation and visual function assessed by Humphrey visual fields and electrophysiological testing over at least 6 months and then 1 year.. Tacrolimus was commenced in 25 patients (mean age 50.4±10.8 years) and was well tolerated in 21 patients (84%). It was necessary to stop the tacrolimus in four patients. No patient showed major changes in renal function: 3/21 patients (14.28%) showed slightly abnormal (less than 30%) function at the end of the first month of treatment; 1/21 (4.76%) patients at 3 months, but at the end of a 6-month treatment period only 1/21 patients (4.76%) showed minor abnormality in renal function. The mean daily prednisolone dose was 19.7 mg at the beginning of the study, which had fallen to 6.9 mg at the end (t=5.071, p=0.001). Visual acuity mostly remained stable. Visual fields improved over time (mean improvement in Humphrey mean deviation, right eye=1.8±2.4 dB, t=3.821, p=0.004; left eye=1.9±2.7, dB, t=3.06, p=0.007). Electrophysiological function showed improvement in 10 patients, and in four patients an initial deterioration in function improved following tacrolimus dose adjustment.. Tacrolimus has a good safety profile for long-term use in patients with BRC as a second-line agent enabling steroid sparing and visual function stabilisation or improvement.

To evaluate the success of single-agent immunosuppression for patients with the posterior uveitides, birdshot chorioretinitis, multifocal choroiditis with panuveitis, and punctate inner choroiditis.. Retrospective case series.. setting: Tertiary care uveitis practices. population: Patients initiated on immunomodulatory therapy. intervention: Patients were treated with prednisone 1 mg/kg and mycophenolate 2 g daily. Prednisone was tapered after 1 month. Immunosuppression was escalated to mycophenolate 3 g daily, with addition of a second agent, as needed, to achieve treatment success. outcome measure: Treatment success, defined as no disease activity with prednisone dose ≤10 mg daily, at 6, 12, and 24 months.. Twenty-seven patients were followed. Mean presentation and 2-year follow-up acuities were 20/41 and 20/42, respectively. For birdshot chorioretinitis, mean (±standard deviation) quantitative Goldmann visual field scores improved from 761 ± 69 degrees (IV/4 isopter) and 496 ± 115 degrees (I/4 isopter) at presentation to 784 ± 57 degrees and 564 ± 125 degrees, respectively. Prednisone was successfully tapered in 95% of patients; mean prednisone doses at 1 and 2 years were 5.3 ± 4.1 and 5.7 ± 4.8 mg/day, respectively. At 2 years, prednisone was discontinued in 11% of patients. Treatment success was achieved in 74% of patients on 1 immunosuppressant, and in an additional 21% of patients on 2 agents, for an overall 95% success rate at 2 years.. Posterior uveitides can be treated with 1 agent in most patients, but the data suggest a need to escalate therapy to higher mycophenolate doses, and in one fifth of cases to add a second agent to maintain disease suppression with acceptably low prednisone doses.
