Ocular Surface Disease in Patients With Atopic Dermatitis Treated With Dupilumab: A Prospective Case-Control Study

PURPOSE

The aim of this study was to evaluate the variation of dry eye disease (DED) prevalence in patients with atopic dermatitis (AD) treated with dupilumab.

METHODS

This prospective case-control study included consecutive patients with moderate-to-severe AD scheduled for dupilumab between May and December 2021 and healthy subjects. DED prevalence, the Ocular Surface Disease Index, tear film breakup time test, osmolarity, Oxford staining score, and Schirmer test results were collected at baseline, 1 month, and 6 months after dupilumab therapy. The Eczema Area and Severity Index was assessed at baseline. Ocular side effects and discontinuation of dupilumab were also recorded.

RESULTS

Seventy-two eyes from 36 patients with AD treated with dupilumab and 36 healthy controls were included. Prevalence of DED increased from 16.7% at baseline to 33.3% at 6 months in the dupilumab group ( P = 0.001), whereas it remained unchanged in the control group ( P = 0.110). At 6 months, the Ocular Surface Disease Index and Oxford score increased (from 8.5 ± 9.8 to 11.0 ± 13.0, P = 0.068, and from 0.1 ± 0.5 to 0.3 ± 0.6, P = 0.050, respectively), the tear film breakup time test and Schirmer test results decreased (from 7.8 ± 2.6 s to 7.1 ± 2.7 s, P < 0.001, and from 15.4 ± 9.6 mm to 13.2 ± 7.9 mm, P = 0.036, respectively) in the dupilumab group, whereas they remained stable in the control group ( P > 0.05). Osmolarity was unchanged (dupilumab P = 0.987 and controls P = 0.073). At 6 months after dupilumab therapy, 42% of patients had conjunctivitis, 36% blepharitis, and 2.8% keratitis. No severe side effects were reported, and none of the patients discontinued dupilumab. No association between Eczema Area and Severity Index and DED prevalence was shown.

CONCLUSIONS

DED prevalence increased in patients with AD treated with dupilumab at 6 months. However, no severe ocular side effects were found and no patient discontinued therapy.

Visual symptoms in a patient treated with MEK inhibitors

PURPOSE

to report an uncommon presentation of Encorafenib-Binimetinib retinal side effects.

CASE REPORT

A 56-year-old Caucasian woman, naïve to previous chemotherapies, was started on Encorafenib/Binimetinib for metastatic melanoma. After seven hours from the first 45 mg Binimetinib dose, the patient developed blurry vision with coloured halos. The symptoms were transient and the following day a complete ophthalmological examination revealed the presence of subretinal fluid (SRF) at Optical coherence tomography (OCT). After one week, the patient remained asymptomatic, with no signs of SRF at the follow up reevaluation. However, six weeks later, the symptoms originally experienced with the first drug intake appeared again. This time fundus examination revealed an irregular macular region. At infrared OCT an almond shaped hyporeflective lesion, surrounded by hyperreflectivity, was demonstrated without signs of SRF. Encorafenib/Binimetinib was continued at the same dose and strict monitoring was scheduled, according to the European Medicine's Agency indication to withhold the drug only in presence of symptomatic retinal pigment epithelial detachment.

CONCLUSION

Visual symptoms associated with SRF induced by Binimetinib have been described in the literature. In our case, visual symptoms were experienced by the patient at different times, both with and without evidence of SRF. This finding seems to suggest that while Binimetinib-induced SRF is an asymptomatic finding in most cases, with excellent outcome and rapid resolution, visual symptoms could be initially triggered by detectable SRF, yet persist without any further evidence of abnormal fluid accumulation and manifest intermittently.

Retinoid-associated myopia in dermatologic patients: a systematic review

Systemic retinoids are among the most prescribed drugs in dermatology, thanks to their activity as proliferation modulators and keratinization normalizers. Common side effects such as blood lipid disorders, xerosis and photosensitivity are well established and usually dose dependent. Conversely, retinoid-associated ocular disturbances have been reported, yet with differences in terms of frequency and manifestations. As data regarding a potential correlation with refractive errors are heterogenous and have not been previously thoroughly addressed, we performed a systematic review of the literature with the aim of comprehensively evaluating the current evidence regarding retinoid-associated myopia in dermatologic patients.
