Topical Betamethasone Treatment of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis with Ocular Involvement in the Acute Phase.

PURPOSE

To clarify the importance of administering topical steroids for the treatment of Stevens-Johnson syndrome (SJS) / toxic epidermal necrolysis (TEN) with ocular involvement in the acute phase.

DESIGN

Retrospective case series.

METHODS

Using the medical records of acute SJS/TEN patients treated at the Kyoto Prefectural University of Medicine Hospital, Kyoto, Japan, between July 2006 and July 2017, the ocular findings, topical steroid dosage, systemic steroid dosage, and ocular sequelae were retrospectively examined. The level of cytokines in tear fluid and serum samples was also analyzed.

RESULTS

This study involved 13 cases. In 10 cases in whom the clinical courses were recorded before the start of steroid therapy, the mean acute ocular severity score (AOSS: 3 = very severe; 2 = severe; 1 = mild; 0 = none) was 2.8 ± 0.4 points in the severest phase. The mean systemic steroid dose after steroid pulse therapy was 694 ± 386 mg and the mean topical steroid (0.1% betamethasone eye drop and ointment) dose was 13.4 ± 3.3 times daily in the severest phase. Analysis of cytokine levels of 4 cases showed that a cytokine storm occurred in the tear fluid after the steroid pulse therapy. At final follow-up, 16 eyes of 8 patients had a logMAR visual acuity of ≤0, and no serious ocular sequelae were observed.

CONCLUSIONS

In patients with SJS/TEN, ocular surface inflammation remains strong even after systemic inflammation has improved post steroid pulse therapy, thus suggesting that both systemic and topical steroid therapy should be administered appropriately.
