RESUMO
ABSTRACT Objective: To report a case of anterior uveitis caused by Euphorbia milii sap and review all reported cases of keratouveitis related to this species. Methods: A 64-year-old male patient presented with a 10-day history of reduced visual acuity, pain, and photophobia in the left eye after an accidental contact with Euphorbia milii sap. Best-corrected visual acuity was initially 20/200. Upon examination, ciliary injection, mild corneal edema; fine keratic precipitates, and significant anterior chamber reaction. There was no vitritis, and fundoscopy was unremarkable. The patient initiated on topical steroid and tropicamide. Results: Best-corrected visual acuity in left eye improved to 20/20 after using eyedrops for 3 weeks, associated with complete resolution of anterior uveitis. Over the following 6 months, best-corrected visual acuity remained stable, and no evidence of recurrent inflammation was observed. Conclusion: To the best of our knowledge, this is the third reported case of keratouveitis caused by Euphorbia milii sap. As observed in other cases of keratouveitis caused by sap of this species, the clinical course is benign and characterized by moderate reaction of the anterior chamber, and corneal involvement of variable intensity.
RESUMO O objetivo foi relatar um caso de uveíte anterior induzida pela seiva da Euphorbia milii e revisar todos os casos relatados de ceratouveíte causados por essa espécie. Paciente do sexo masculino, 64 anos, apresentou história de 10 dias de evolução com redução da acuidade visual, dor e fotofobia no olho esquerdo, após contato acidental com a seiva da planta Euphorbia milii. A acuidade visual com melhor correção era inicialmente 20/200. O exame revelou injeção ciliar, edema de córnea leve, precipitados ceráticos finos e reação de câmara anterior significativa. Não havia vitreíte, e a fundoscopia não exibia alterações. Foram iniciados colírios de esteroides e tropicamida. A acuidade visual no olho esquerdo melhorou para 20/20 em 3 semanas com a utilização dos colírios, além de se ter alcançado a resolução completa da uveíte anterior. Nos 6 meses seguintes, a acuidade visual permaneceu estável, e não foi observada evidência de recorrência da inflamação. Até então, este é o terceiro caso relatado de ceratouveíte pela seiva da Euphorbia milii. Como visto nos demais casos de ceratouveíte induzidos pela seiva dessa espécie, o curso clínico é benigno e caracterizado por reação moderada da câmara anterior, com envolvimento corneano de intensidade variável.

BACKGROUND: Chronic kidney disease (CKD) is a public health problem worldwide, and proteinuria is a well-established marker of disease progression in CKD patients. Propolis, a natural resin produced by bees from plant materials, has anti-inflammatory, immunomodulatory, and anti-oxidant properties, as well as having been shown to have an antiproteinuric effect in experimental CKD. The aim of this study was to evaluate the impact of Brazilian green propolis extract on proteinuria reduction and the changes in the estimated glomerular filtration rate (eGFR). METHODS: This was a randomized, double-blind, placebo-controlled study including patients with CKD caused by diabetes or of another etiology, 18-90 years of age, with an eGFR of 25-70 ml/min per 1.73 m2 and proteinuria (urinary protein excretion > 300 mg/day) or micro- or macro-albuminuria (urinary albumin-to-creatinine ratio > 30 mg/g or > 300 mg/g, respectively). We screened 148 patients and selected 32, randomly assigning them to receive 12 months of Brazilian green propolis extract at a dose of 500 mg/day (n = 18) or 12 months of a placebo (n = 14). RESULTS: At the end of treatment, proteinuria was significantly lower in the propolis group than in the placebo group-695 mg/24 h (95% CI, 483 to 999) vs. 1403 mg/24 h (95% CI, 1031 to 1909); P = 0.004-independent of variations in eGFR and blood pressure, which did not differ between the groups during follow-up. Urinary monocyte chemoattractant protein-1 was also significantly lower in the propolis group than in the placebo group-58 pg/mg creatinine (95% CI, 36 to 95) vs. 98 pg/mg creatinine (95% CI, 62 to 155); P = 0.038. CONCLUSIONS: Brazilian green propolis extract was found to be safe and well tolerated, as well as to reduce proteinuria significantly in patients with diabetic and non-diabetic CKD.
