Texte intégralDupilumab has proven its efficacy in the treatment of moderate to severe atopic dermatitis (AD). However, the occurrence of ocular adverse events (OAEs) has been reported. The objectives of this work were to describe the incidence and nature of OAEs induced by dupilumab in AD patients, to evaluate potential predisposing factors, and to understand their molecular bases. We conducted a first single-center, prospective, real-life study in adult AD patients treated with dupilumab, who were systematically examined by an ophthalmologist before and during treatment. We included 46 patients with a median initial SCORing of AD (SCORAD) of 46.0 (interquartile range: 34.5-55.5). 34.8% of patients experienced OAEs, often mild to moderate, but leading to interruption of dupilumab for two patients. The majority of patients developed or worsened dry eye. Six patients (13%) developed conjunctivitis de novo. Dupilumab-induced OAEs were associated with dry eye with superficial punctuate keratitis (Odds ratio (OR) = 6.3 95% confidence interval (CI): [1.3-31.6]), eyelid eczema (OR= 8.7; 95% CI: [1.8-40.6]), a history of food allergy (OR = 3.8; 95% CI: [1.002-14.070]) and/or serum IgE levels > 1.000 kU/L (OR = 10.6; 95% CI: [1.2-91.3]). We then participated to a national multicenter study which included 181 patients. Thirty-four patients (18.7%) presented blepharoconjunctivitis induced by dupilumab: either de novo (n=32; 17.6%) or by worsening of a pre-existing condition (n=2; 1.1%). Most events (27/34; 79.4%) were moderate. Multivariate analysis showed that AD with head and neck involvement (OR = 7.254; 95% CI [1.938-30.07]; p = 0.004), erythroderma (OR = 5.635; 95% CI [1.635] -21.50]; p = 0.007) and the presence of dry eye syndrome before treatment (OR = 3.51; 95% CI [3.158-13.90]; p = 0.031) were independent factors associated with dupilumab-induced blepharoconjunctivitis. The SCORAD or the response to treatment (% improvement in SCORAD at W16), a history of allergic conjunctivitis, asthma or rhinitis were also not significantly associated with the occurrence of OAE. Finally, we conducted a bicentric study, comparing the transcriptome (analyzed by DNA microarrays and RT-qPCR) and the expression of the chemokine CCL20 (by ELISA) of conjunctival cells, collected by conjunctival impression, on AD patients before (M0) and 4 months after dupilumab beginning (M4). Thirty-six patients were included and divided in two groups, according their ophthalmological status at M4: one group of 12 who developed OAE (OAE+) and another group of 24 who did not (OAE-). In multiple analysis of the full transcriptome, we found 52 differentially expressed genes (DEG) between OAE+/M0 and OAE-/M0, 113 DEG between OAE+/M4 and OAE-/M4, two DEG between OAE+/M0 and OAE+/M4, and none DEG between OAE-/M0 and OAE-/M4. Ingenuity Pathway Analysis enrichment with a special interest in diseases, mainly indicated a psoriasis signature. Among the 15 DEG selected for RT-qPCR validation, only 7 were significant: CCL20, IL-19, NOX1, NOS2, SLC26A4 and S100A12 were up-regulated, whereas MUC-7 was downregulated in OAE+/M4 vs OAE-/M4 patients. CCL20 protein quantification by ELISA confirmed an over-expression between M0 and M4 for the two groups. In conclusion, most cases of dupilumab-induced blepharoconjunctivitis are de novo. Pre-existing factors (dry eye syndrome, AD with eyelid, head and neck) are associated with an increased risk of OAE. Dupilumab seems to switch AD immunological profile of OAE patients from Th2 to Th17, particularly involved in psoriasis

Texte intégralOBJECTIVES: Evaluate ocular surface parameters, impression cytology (IC) and dry eye (DE) symptoms of patients with Ankylosing Spondylitis (AS) and Rheumatoid Arthritis (RA). Classify DE severity grade. Analyse prospectively clinical and laboratory, as well as ocular surface parameters of AS and RA patients, submitted to anti-TNF therapy. METHODS: This prospective study initially (baseline) enrolled 36 AS patients and 20 RA patients who were compared to a control group of 39 and 24 healthy volunteers for the AS group and RA group, respectively. From the initial group, 14 consecutive AS and 20 consecutive RA patients received anti-TNF therapy. They underwent the following exams: Schirmer I test, tear break-up time, vital dyes staining of the ocular surface, a questionnaire for dry eye symptoms- Ocular Surface Disease Index (OSDI), and conjunctival IC. Laboratory tests for inflammatory activity were assessed by erythrocyte sedimentation rate and C- reactive protein (ESR and CRP). The Bath Ankylosing Spondylitis Activity Index and Bath Ankylosing Spondylitis Functional Index (BASDAI and BASFI, respectively) in AS and Disease Activity Score 28 (DAS 28) in RA analyzed disease activity parameters. Besides, the Health Assessment Questionnaire evaluated the quality of life in both group of diseases. These measurements were taken at baseline (BL) and repeated at 3 months and 12 months (3M and 12M, respectively) after the beginning of anti-TNF therapy. RESULTS: At the baseline moment, AS patients presented mild to moderate DE (80.5% vs 43.6%, p=0.01) and a higher score of altered IC (55% vs 12.8%, p=0.007) associated with the systemic inflammatory activity (ESR and CRP, p < 0.001) when compared to healthy volunteers. The longitudinal evaluation of anti- TNF treatment showed an improvement of aqueous tear production (BL: 13.7 +- 11.3 mm, 3M: 18.3 +- 11.1 mm and 12M: 19.3 +- 9,0 mm, p=0.04). The IC also improved (BL: 78.6% altered IC, 3M: 57.1% and 12M: 35.7%, p=0.03). There was a parallel amelioration of systemic inflammatory markers and disease activity (p < 0.05). Concerning the RA group of patients, at the baseline moment, there was a higher frequency of DE (75% vs 4%, p < 0.001) as well as mild DE severity grade (65% vs 4%, p < 0,001) associated with moderate symptoms of DE (OSDI score: 24.0 +- 17.6 vs 7.5 +- 14.3, p=0.001) when compared to healthy volunteers. This group of patients also presented higher frequency of meibomian gland dysfunction (55% vs 8.3%, p=0.001), a worse score of IC (1.0 +- 0.6 vs 0.0 ? 0.2, p=0.001) and lower goblet cells count (431.3 +- 209.5 cells/mm2 vs 804.8 +- 383.2 cells/mm2, p< 0.001) when compared to the control group. The prospective analysis of RA patients treated with anti-TNF drugs demonstrated an increase of Schirmer\'s test (BL: 11.8 +- 6.7, 3M: 21.0 +- 10.4, 12M: 23.0 +- 9.7, p < 0.001) and an improvement of cytological grade (BL: 1.0 +- 0.6, 3M: 0.8 +- 0.6, 12M: 0.5 +- 0.5, p=0.005) and goblet cells density (BL: 429,0 +- 211.7 cells/mm2, 3M: 908,0 +- 291.4 cells/mm2, 12M: 1265.4 +- 430.6 cells/mm2, p=0.001). The systemic inflammatory markers (ESR and CRP) also improved throughout the treatment period (p=0.005 and p=0.006, respectively). CONCLUSION: Patients with AS and RA enrolled in this study presented a higher prevalence of mild to moderate DE associated with altered IC. The prompt and maintained aqueous tear and conjunctival cytology recovery, especially the goblet cells, in patients submitted to anti-TNF therapy seem to represent the improvement of inflammatory condition. This histological outcome may have an influence as a biomarker of ocular surface inflammation

Thyroid orbitopathy (TO), an autoimmune disease, is complicated with ocular surface disorder leading to discomforts of patients. Dry eye is highly prevalent in TO patients. Although previous studies have proposed factors of increased corneal exposure predisposing to dry eye disease in TO, inflammation in ocular surface may be another main contribution. Recent studies have focused on the inflammatory process to explain pathogenesis of dry eye and certain evidences have discovered. Since TO is a disorder of autoimmune origin, its association with dry eye is highly speculated to be inflammation-related. Inflammation of ocular surface has never been well studied in such cases of TO with dry eye. So far, no extensive study has been published in this aspect and hypothesis. In this study we will assay cellular inflammation in ocular surface and cytokines profiles in patients of TO combined with dry eye. Conjunctival impression cytology (CIC) will be studied with immunofluorescent assay (IFA). TO and dry eye patients were diagnosed with Schirmer test, tear break-up time, thyroid function and clinical signs. Conjunctival impression cytology (CIC) was combined with immunological stain of Interleukin-1???n?vIL-1???w, IL-1???nand IL-6?|?nThe grading of the immunological impression cytology (IC) was compared to clinical activity score of TO. All the markers of IL-1???z?nIL-1?? and IL-6 were highly positive in patients of TO with dry eyes. However, in normal control group, IL-1?? was similarly highly positive. A slight parallel trend was observed between clinical inflammatory score and grading of immunological IC. This study is the first to delineate the immunological IC of TO patients with dry eyes. The prospect of this study is to investigate the pathogenesis of dry eye occurring in TO. Our findings suggest that conjunctival cytokines IL-1α, IL-1β and IL-6 may play a role. This model of study is promising for further experiment of more inflammatory cytokines, and can be used as an outcome for investigation of treatment, such as anti-cytokine or immuno-suppression therapy, in such patients or other ocular surface inflammatory disorders.

Thyroid-associated Orbitopathy (TAO or TO) or Graves’ Orbitopathy (GO) is an autoimmune inflammatory eye disease associated with thyroid disorders, which clinical manifestation occurr as a combination of inflammation, increase of orbital fat and extra ocular muscle volume within the orbital space. The incidence rate of this disease is 16 women and 3 men per 100,000 populations. Autoantibodies to both TSHr (Thyroid stimulating hormone-receptor) and IGF-1r (insulin-like growth factor 1 receptor) displayed in the orbital fibroblast contributed in the development of the orbital changes in TO. In this study, we described the inflammation in TO patient’s ocular surface by morphological and immunological impression cytology of conjunctival epithelium cells layer. We also evaluated the eyelid changes in TO including eyelid retraction and swelling using an ultrasound biomicroscopy (UBM) imaging features. This enables us to observe the correlation of eyelid’s structure thickness and the pathology of the aforementioned changes. We found the morphological changes of conjunctival epithelial cells including low quality of cell-to-cell adhesion, increased nucleo-cytoplasmic ratio of cells and absence of mucus and goblet cells. The positivity of pro-inflammatory cytokines-released from the cells (IL-1α, IL-1β and ICAM) was also observed in immunostaining examination. Ultrasound Biomicroscopy (UBM) measurement gave a significant different thickness of eyelid and levator aponeurosis (LA) layer in TO compare to normal subject, but LA thickness was less correlated with the clinically upper eyelid retraction. Since its causes are multifactorial, eyelid retraction could be seen as a restrictive problem where lid retractors (LPS and Muller muscle) may also become inflamed and subsequent fibrosis, scarring to the adjacent connective tissue might cause retraction. Eyelid swelling could not be clearly imaged by UBM, because eyelid skin (thin epidermis and dermis with subcutaneous tissue) was observed as an echo-dense line at the water cup medium-upper eyelid interface. We emphasized the inflammation of ocular surface in TO patient by using impression cytology method and the clinical use of UBM in eyelid structure study related to TO clinical finding. This model of study support the anti-inflammatory drug application for TO patients with severe dry eye and UBM study provides information about anatomy of TO eyelid.
