Purpose: To report the clinical outcome of the treatment of dry eyes using 0.03% tacrolimus eye drops (olive oil + tacrolimus 0.03%) (Ophthalmos, Sao Paulo, Brazil). Methods: Sixteen eyes of 8 patients with Sjogren syndrome dry eyes (age, 51.13 +/- 9.45 years) were enrolled in this study (prospective noncontrolled interventional case series). Patients were instructed to use topical 0.03% tacrolimus eye drops twice a day (every 12 hours) in the lower conjunctival sac. Schirmer I test, break-up time, corneal fluorescein, and rose bengal staining score were performed in all patients 1 day before, and 14, 28, and 90 days after treatment with 0.03% tacrolimus eye drops. Results: The average fluorescein staining and rose bengal staining scores improved statistically significantly after 14 days of treatment and improved even more after 28 and 90 days. The average Schirmer I test did not improve statistically significantly after 28 days of treatment, although we did observe a significant improvement after 90 days of treatment with 0.03% tacrolimus eye drops. The average break-up time did not improve statistically after 14 days of treatment, although we observed a significant improvement after 28 and 90 days of treatment with 0.03% tacrolimus eye drops. Conclusions: Topical 0.03% tacrolimus eye drops successfully improved tear stability and ocular surface status in patients with dry eyes.

INTRODUÇÃO: A conjuntivite alérgica é a forma mais comum de doença alérgica que afeta o olho. Neste trabalho, desenvolvemos um modelo murino reprodutível e simular a doença humana, para possibilitar o estudo dos mecanismos fisiopatológicos da conjuntivite alérgica crônica. MÉTODOS: Imunizamos os camundongos BALB/c e C57Bl/6 com extrato do ácaro Dermatophagoides pteronyssinus (Dpt). Foi realizada a dissecção dos linfonodos ilíacos e para-aórticos, e a enucleação dos olhos. O plasma obtido pela punção cardíaca foi utilizado para a dosagem de IgE e IgG totais e específicas para Dpt. Os olhos enucleados foram enviados para estudo anátomo-patológico da conjuntiva e córnea. RESULTADOS: 1) Houve uma diferença estatisticamente significante entre as duas linhagens (BALB/c e C57Bl/6) para os grupos imunizados com 5 ?g e 500 ?g na gradação clínica e histopatológica, dosagens de IgE Total e Específica, proliferação de linfócitos específica para Dpt e IgG Específica, e na dosagem das IL-5, IL-8 e IL-13; 2) Os níveis de IgG Total não se mostraram significantes para as duas linhagens nos grupos imunizados com 5 ?g e 500 ?g; 3) Os níveis de IL-4 e IL-10 tiveram uma diferença significante nos animais da linhagem BALB/c imunizados com 5 ?g e 500 ?g...

Pós-graduação em Genética - IBILCE; Allergic conjunctivitis (AC) is a complex disease of the immune system which includes mast cell degranulation in the conjunctiva and release of mediators that trigger inflammatory cell infiltration in this mucous membrane. Among the anti-inflammatory mediators, we highlight the protein galectin-1 (Gal-1) which regulates the process of leukocyte transmigration, release of cytokines and mast cell degranulation. However, its role in ocular inflammation has been little studied. BALB/c male mice were sensitized subcutaneously with 5μg of ovalbumin (OVA) on days 0 and 7 and challenged by eye drops containing OVA (250 μg) once daily (days 14, 15 and 16). For pharmacological treatment (days 14-16) animals received intraperitoneally recombinant Gal-1 (rGal-1; 0.3 μg /animal) or dexamethasone (Dex; 1 mg/kg). The clinical score was performed twenty minutes after OVA challenge (days14-16). After 4 and 24 hours of last OVA challenge, the animals were sacrificed and the followed analyses were performed: histopathology and quantification of inflammatory cells in the bulbar conjunctiva and blood; plasma anti-OVA IgE levels by ELISA; cytokines (IL-2, IL-4, IL-5, IL-10, IL-13, TNF-α and IFN-γ) and chemokines (RANTES...

INTRODUCTION: Canine atopic dermatitis (cAD) is a very common disease, but little is known about eye involvement. The conjunctival provocation test (CPT) is used in human to study the ocular response to allergenic stimuli and to evaluate anti-allergic therapy. To our knowledge it has not been used in dogs. OBJECTIVES: To evaluate the prevalence of ocular signs in a population of atopic dogs and relate these with clinical cAD scores; and the usefulness of CPT for dust mites in atopic dogs with itchy eyes. PROCEDURES: Sixty cAD patients were evaluated for (i) ocular signs of allergic conjunctivitis including conjunctival hyperemia, chemosis, epiphora, ocular discharge, pruritus and corneal involvement, graded 0 to 3 according to severity, and (2) cAD Extent and Severity Index (CADESI-03). Additionally, CPTs for Dermatophagoides farinae (n = 12) and Dermatophagoides pteronyssinus (n = 12) were performed in sensitized atopic dogs and 24 control dogs. RESULTS: Periocular and ocular signs of allergy were present in 60% (36/60) of cases. Conjunctival hyperemia (90%) was the most common sign. Severity of ocular signs was significantly correlated with eye pruritus (r(s)  = 0.690, P = <0.001) and skin lesions score for head region (r(s) = 0.261...

Dissertação de Mestrado Integrado em Medicina Veterinária; A osmolaridade do filme lacrimal é um parâmetro útil para avaliar a qualidade da lágrima. Esta representa a concentração de catiões (sódio, potássio, cálcio, magnésio, ferro e cobre) e de aniões (cloretos, carbonatos e fosfatos) dissolvidos na porção aquosa da lágrima. O objectivo deste estudo é avaliar a osmolaridade do filme lacrimal em cães atópicos com conjuntivite alérgica (CA). A CA é muito prevalente nos cães que têm dermatite atópica (DA). No entanto esta afeção é um diagnóstico de exclusão, pois não existe um teste simples e eficaz para a diagnosticar. Foi incluído no estudo um grupo controlo (n=20) e um grupo de cães atópicos com sinais de CA (n=20). Todos os animais foram sujeitos a exame dermatológico, bem como a exame oftálmico para avaliação dos sinais clínicos de CA (quemose, prurido, epífora, hiperémia conjuntival, corrimento ocular e presença de doença da córnea) e sua classificação numa escala de 0-3. Adicionalmente o grupo dos atópicos foi classificado segundo a escala CADESI-03. Avaliou-se a osmolaridade do filme lacrimal com o sistema TearLab osmolarity® (TearLab Corp., San Diego, E.U.A.). O estudo estatístico foi realizado com GraphPad Instat® recorrendo aos testes de Mann- Whitney e regressão linear. Após avaliação dos dados...

Dissertação de Mestrado Integrado em Medicina Veterinária; A atopia é uma doença frequente no cão, mas pouco se sabe acerca do envolvimento ocular, desconhecendo-se a prevalência e o impacto da conjuntivite alérgica (CA) na dermatite atópica canina (DAc). O teste de provocação conjuntival (TPC) é um modelo útil ao seu estudo, sendo utilizado na avaliação da eficácia de várias formas de tratamento, incluindo a imunoterapia alergénio-específica (ITAE). Através da realização de TPC em pacientes atópicos com sensibilização a Dermatophagoides farinae (Df) pretendeu-se avaliar a contribuição deste alergénio nas manifestações oculares e a eficácia da imunoterapia alergénio específica rush (ITAEr) na remissão dos sinais oculares e cutâneos. Foram incluídos no estudo 15 pacientes (n=15) com diagnóstico de DAc e sinais compatíveis com CA. Numa primeira fase todos os animais foram submetidos a TPC para Df e avaliados quanto ao prurido e quanto à gravidade das lesões dermatológicas através do Canine Atopic Dermatitis Extend and Severity Index (CADESI-03). O TPC foi realizado com doses crescentes do alergénio (0.08, 0.4 e 2 BU/mL) até ao aparecimento de um score positivo (≥6), dado pelo somatório das classificações de hiperémia conjuntival...

PURPOSE: The purpose of this study was to analyze the cutaneous sensitivity to a variety of allergens in patients with vernal keratoconjunctivitis (VKC) and to demonstrate the relation between skin response and clinical aspects of the disease. METHODS: Twenty patients with vernal keratoconjunctivitis were randomly chosen from the External Disease and Cornea Sector. They were clinically evaluated, and a score ranging from 0 to 20 was applied based on signs and symptoms on ophthalmic examination. All subjects underwent a skin prick test against standardized allergens, such as house dust mites D. pteronyssinus, D. farinae, and Blomia tropicalis, as well as allergens from cat, dog, fungi and feather. RESULTS: Seventy-five per cent of patients were positive for at least one of the allergens tested. House dust mites were responsible for the majority of the cases (75%). There was a poor correlation between the clinical score and sensitivity to allergens (r= - 0.119 for fungi; r= - 0.174 for dog; r= - 0.243 for house dust mites; r= - 0.090 for feather). A significant correlation was found only for cat allergen extract (r = - 0.510; p=0.024). CONCLUSIONS: Our study demonstrated poor correlation between cutaneous hypersensitivity tests and clinical findings in patients with vernal keratoconjuntivitis. We concluded that skin response to inhalant allergens is not a useful test to identify clinical severity and chronicity of inflammatory process in this disease.

The role of platelet-activating factor (PAF) as a mediator of increased conjunctival vascular permeability was investigated in a guinea-pig model of immediate hypersensitivity. Vascular permeability of the conjunctiva was determined by measuring the albumin content in lavage fluid (LF) after topical challenge with either PAF or ovalbumin. PAF produced a dose-dependent increase of the vascular permeability within minutes. Topical pretreatment with levocabastine, a potent histamine H1-antagonist demonstrated no effect towards the vascular permeability in response to PAF provocation. Pretreatment with eyedrops containing the specific PAF antagonist BN 52021 (1%) showed a significant inhibition of the vascular permeability (60.2%) and the clinical score (27.5%) after PAF challenge. In sensitized guinea-pigs, levocabastine showed a marked inhibition of both the vascular permeability (80.5%) and the clinical score (70%) after topical challenge with ovalbumin. BN 2021, although to a lesser extent, showed a similar effect towards the vascular permeability (26.8%) and the clinical score (28%) after antigen provocation. When BN 52021 and levocabastine were administered in combination, the vascular permeability was significantly decreased after antigen challenge in comparison with eyes pretreated with levocabastine alone. These results indicate that PAF plays a role in the acute phase of allergic conjunctivitis in the guinea-pig.

When defining allergic outcomes in epidemiology studies results of the skin prick test (SPT) panel is often dichotomized as positive/negative or categorized based on the number of positive responses. Item Response Theory (IRT) models, however, may prove to be a better alternative with the ability to generate scores that account for both type and number of positive SPTs. IRT was applied to SPT responses administered to 537 children at age two in order to determine predictability of allergic disease at age four. The children received SPTs to 15 aeroallergens and two foods. Atopy predisposition scores were obtained from the IRT model using the posterior distribution of the latent trait, atopy. These scores were used to predict persistent wheeze, rhino-conjunctivitis, and eczema at age four. Results were compared to the dichotomized and categorical (positive to ≥ 2, positive to one, versus negative to all allergens) SPT variables. At age two, 39% of children had at least one positive SPT. All three allergic disease outcomes were significantly associated with IRT atopy scores: persistent wheeze odds ratio (OR)=1.7 (95% confidence interval (CI): 1.2, 2.3); rhino-conjunctivitis OR=1.7 (95% CI:1.2, 2.3); eczema OR=1.6 (95% CI: 1.2, 2.3). In contrast...

This review will provide new information related to pathophysiology and management of specific diseases that have been addressed by selected articles published in the Italian Journal of Pediatrics in 2013, focusing on allergology, endocrinology, gastroenterology, hypertension, infectious diseases, neonatology, neurology, nutrition and respiratory tract illnesses in children. Recommendations for interpretation of skin prick test to foods in atopic eczema, management of allergic conjunctivitis, hypertension and breastfeeding in women treated with antiepileptic drugs and healthy breakfast have been reported. Epidemiological studies have given emphasis to high incidence of autoimmune disorders in patients with Turner syndrome, increasing prevalence of celiac disease, frequency of hypertension in adolescents, incidence and risk factor for retinopathy of prematurity. Advances in prevention include elucidation of the role of probiotics in reducing occurrence of allergies and feeding intolerance, and events of foetal life that influence later onset of diseases. Mechanistic studies suggested a role for vitamin D deficiency in asthma and type 1 diabetes and for reactivation of Varicella-Zoster virus in aseptic meningitis. Regarding diagnosis...

Purpose. To evaluate the efficacy of using topical cyclosporin A 0.05% (Restasis) for the treatment of paediatric allergic conjunctivitis. Methods. This retrospective study included consecutive cases of paediatric allergic conjunctivitis treated with Restasis between 2010 and 2013. Subjects with follow-up time less than 3 months after using Restasis were excluded. Itch severity score, symptom score, and sign score were compared before (baseline) and 3 months after using Restasis. Results. In 27 eyes of 14 patients (mean age 10.8 ± 3.2 years), 44.4% had allergic conjunctivitis, 33.3% had vernal keratoconjunctivitis, and 22.2% had atopic keratoconjunctivitis. The mean duration of ocular symptoms was 20.4 ± 13.2 months. 92.6% of subjects were using steroid eye drop before Restasis. After 3 months of topical Restasis, there were statistically significant reductions in the symptom, sign, and itch severity scores compared with baseline (all P ≤ 0.001) and 78.6% of subjects were able to be tapered off steroid eye drops. Conclusion. Topical Restasis was effective and safe in significantly reducing ocular itchiness, sign, and symptom scores at 3 months after use in paediatric allergic ocular conditions.

Fractioned exhaled nitric oxide (FeNO) is a noninvasive marker of inflammation in asthmatic patients. FeNO can be used to monitor airway inflammation, but individual responses make tailored interventions based on FeNO difficult. The correlation between the asthma control test (ACT), FEV1, and FeNO was evaluated in this study to ascertain the correct usage of FeNO with different asthma phenotypes regarding their control, allergy, comorbidity, obesity, age, smoking status, and severity. ACT, pulmonary function, and FeNO in 416 asthmatic patients on combined therapy were retrospective evaluated. Correlations between these parameters and the FeNO levels in different asthma phenotypes were calculated. In the study population, FeNO was 31.8 ± 28.5 parts per billion (ppb), FEV1 was 83.4 ± 19% and ACT was 19 ± 5.2. ACT scores were negatively correlated with FeNO (r = −0.31; p = 0.002). FeNO was different in patients with positive and negative skin-prick test (p < 0.05), with and without allergic rhinitis (p < 0.01), and with and without allergic conjunctivitis (p < 0.01). Significantly higher FeNO levels were found with logistic regression analysis only in patients with a history of emergency room visits (ERVs) (p = 0.024). The rate of the ERV of the patients with an ACT score more than or equal to 20 and with a FeNO value of more than 35 ppb was 22.9%...

Background: The goal of this study was to assess the effect of a controlled adverse environment (CAE) challenge on subjects with both allergic conjunctivitis and dry eye. Methods: Thirty-three subjects were screened and 17 completed this institutional review board-approved study. Subjects underwent baseline ocular assessments and conjunctival allergen challenge (CAC) on days 0 and 3. Those who met the ocular redness and itching criteria were randomized to receive either the controlled adverse environment (CAE) challenge (group A, n = 9) or no challenge (group B, n = 8) at day 6. Thirty minutes after CAE/no-CAE, subjects were challenged with allergen and their signs and symptoms graded. Exploratory confocal microscopy was carried out in a subset of subjects at hourly intervals for 5 hours post-CAC on days 3 and 6. Results: Seven minutes post-CAC, subjects exposed to the CAE had significantly greater itching (difference between groups, 0.55 ± 0.25, P = 0.028), conjunctival redness (0.59 ± 0.19, P = 0.002), episcleral redness (0.56 ± 0.19, P = 0.003) and mean overall redness (mean of conjunctival, episcleral, and ciliary redness, 0.59 ± 0.14, P < 0.001). The mean score at 7, 15, and 20 minutes post-CAC for conjunctival redness (0.43 ± 0.17...

Introduction: The efficacy and safety of the once-daily topical ophthalmic solutions, alcaftadine 0.25% and olopatadine 0.2%, in preventing ocular itching associated with allergic conjunctivitis were evaluated. Methods: Pooled analysis was conducted of two double-masked, multicenter, active- and placebo-controlled studies using the conjunctival allergen challenge (CAC) model of allergic conjunctivitis. Subjects were randomized 1:1:1 to receive alcaftadine 0.25%, olopatadine 0.2%, or placebo. The primary efficacy measure was subject-evaluated mean ocular itching at 3 min post-CAC and 16 h after treatment instillation. Secondary measures included ocular itching at 5 and 7 min post-CAC. Ocular itch was determined over all time points measured (3, 5, and 7 min) post-CAC and the proportion of subjects with minimal itch (itch score <1) and zero itch (itch score = 0) was also assessed. Results: A total of 284 subjects were enrolled in the two studies. At 3 min post-CAC and 16 h after treatment instillation, alcaftadine 0.25% achieved a significantly lower mean itch score compared with olopatadine 0.2% (0.50 vs. 0.87, respectively; P = 0.0006). Alcaftadine demonstrated a significantly lower mean itch score over all time points compared with olopatadine (0.68 vs. 0.92...

Purpose Seasonal and perennial allergic conjunctivitis represent the majority of cases of ocular allergy. This analysis was designed to evaluate the efficacy and safety of once-daily alcaftadine 0.25% in preventing ocular itching associated with seasonal or perennial allergic conjunctivitis. Subjects and methods Pooled data from two double-masked, multicenter, placebo-controlled studies using the conjunctival allergen challenge (CAC) model of allergic conjunctivitis were analyzed. Subjects randomized to receive treatment with alcaftadine 0.25% or placebo were challenged with seasonal (grass, ragweed, trees) or perennial (cat dander, cat hair, dog dander, dust mites, cockroach) allergens, 16 hours after treatment instillation. The primary efficacy measure was subject-evaluated mean ocular itching at 3 minutes post-CAC. Secondary measures included ocular itching at 5 and 7 minutes post-CAC. The proportion of subjects with minimal itch (itch score <1) and zero itch (itch score =0), and safety were also assessed. Results: A total of 189 subjects enrolled in the two studies were treated with alcaftadine or placebo. Overall, 129 subjects were challenged with seasonal allergens and 60 subjects were challenged with perennial allergens. Alcaftadine 0.25% achieved a statistically significant reduction in mean itch score at 3...

Dissertação de Mestrado Integrado em Medicina Veterinária; A conjuntivite alérgica canina (CAc) é uma doença cuja manifestação clínica ocorre nas pálpebras, na conjuntiva e/ou na córnea. Caracteriza-se por reações de hipersensibilidade do tipo I e integra frequentemente a sintomatologia da dermatite atópica canina (DAc). Através do estudo realizado no âmbito da presente dissertação de mestrado, pretende-se contribuir para a caracterização da resposta imunitária da CAc. Nesse sentido, um grupo controlo formado por animais saudáveis (n=10) e um grupo de animais atópicos com conjuntivite alérgica (CA) (n=10) integraram a presente experiência. Ambos foram submetidos a um exame dermatológico e oftalmológico completos, em que se procedeu, apenas para o grupo atópico, à classificação da gravidade das lesões com o Canine Atopic Dermatitis Extent and Severity Index – fourth version (CADESI-4), bem como à avaliação quantitativa dos sinais clínicos de CAc (corrimento ocular, epífora, hiperémia conjuntival, prurido, quemose e queratite concomitante) através da atribuição de um valor entre 0 (ausente) e 3 (grave). Subsequentemente, após a aplicação tópica ocular de anestésico, uma amostra de conjuntiva palpebral medindo cerca de 2x2 mm foi colhida e submetida a quantificação...
