- Fabry’s disease, an eye-kidney disease reviewPublication . Guedes-Marques, M; Mira, F; Ferreira, E; Pinto, H; Maia, P; Mendes, T; Carreira, A; Campos, MFabry’s disease is a recessive X -linked disorder that results from a deficiency of the hydrolase alpha- -galactosidase A (α -Gal A). The absence of α -Gal A enzyme activity leads to accumulation of glycosphingolipid globotryaosylceramide (GL -3) in the lysosomes of a variety of cell types. It can cause skin and ocular lesions, progressive renal, cardiac or cerebrovascular disorders. The authors report the case of a 39 -year -old female who was referred to a nephrology appointment by her ophthalmologist, after the diagnosis of cornea verticillata and posterior subcapsular cataract. This case illustrates the importance of a multidisciplinary evaluation to an effective clinical screening. In males, most symptoms begin in childhood; in females the onset can be observed later and presentation is more variable. Various manifestations often lead to misdiagnosis or are frequently delayed for many years. Enzyme replacement therapy highlights the importance of early diagnosis so that treatment can be initiated before irreversible organ damage occurs.
- Real-world outcomes of anti-VEGF treatment for retinal vein occlusion in PortugalPublication . Vaz-Pereira, S; Marques, I; Matias, JG; Mira, F; Ribeiro, L; Flores, RPURPOSE: Retinal vein occlusion (RVO) is an important cause of visual disability in the modern world. We aim to evaluate the real-world outcomes of patients with RVO treated with anti-vascular endothelial growth factor (VEGF) in Portugal. METHODS: We performed a retrospective, observational, multicenter study including 8 centers across Portugal and 200 patients treated with either ranibizumab or bevacizumab. Data were collected at 3 time points: time of diagnosis (0 time point) and 6 and 12 months after initiating treatment. Demographic and clinical data were collected. RESULTS: Median visual acuity (VA) and central macular thickness (CMT) improved in the branch RVO (BRVO), central RVO (CRVO), bevacizumab, and ranibizumab groups at 6 and 12 months compared to baseline, with CMT improving further only in the CRVO and ranibizumab groups between 6 and 12 months (p = 0.002 and p = 0.001, respectively). The CMT was lower in the ranibizumab group compared to the bevacizumab group both at 6 and 12 months (p<0.02). Median CMT improved in both the good and poor baseline VA groups at 6 and 12 months compared to baseline (p<0.001). Median VA only improved for the group with poor baseline VA at 6 and 12 months of follow-up (p<0.001). Regression analysis identified several baseline variables as predictors of visual outcomes at 6 and 12 months, with different results depending on the analyzed group. CONCLUSIONS: Both treatments were effective, although less effective than results reported in clinical trials. The morphologic response was better with ranibizumab compared to bevacizumab, although functionally there were no differences.
