RESUMO

We present a case of bilateral endogenous endophthalmitis with an extremely rare etiology of Capnocytophaga canimorsus. A 42-year-old asplenic patient with bilateral deterioration of visual acuity presented to the Emergency Department. The sudden deterioration of visual acuity, which prompted the patient to visit the ophthalmologist, was the first sign of the onset of sepsis. The physicians' attention, in addition to poor visual acuity and intense inflammation on ophthalmologic examination, was drawn to the reported flu-like symptoms. They were accompanied by high C-reactive protein results and abnormalities in echocardiography. A blood culture isolated the bacterium Capnocytophaga canimorsus. Immunocompromised patients are particularly susceptible to C. canimorsus infection. Endophthalmitis of this etiology has a very aggressive course, both ophthalmic and systemic. Therefore, quick diagnosis and initiation of adequate therapy are crucial.

RESUMO

Pseudoexfoliation syndrome (PEX) is a clinically important and biologically intriguing systemic disorder of the extracellular matrix. PEX etiopathogenesis was proved to be connected to multiple genes and other factors. However, the exact etiopathogenesis remains unknown. The aim of this study was to analyze miR expression in PEX using next-generation sequencing. An attempt was made to find the most commonly occurring miR in PEX, to evaluate miR that may have an essential role in the etiology of PEX syndrome. In addition, the correlation between the selected miRs' expressions and age was investigated. Anterior lens capsules were obtained during cataract surgery. Next-generation sequencing was conducted on Illumina MiSeq. The average age was 68.2 years (with standard deviation +/- 6.92 years). Ten miRs with the highest level of expression represent approx. 95% of all readings. Four miRs with statistically significant differences in expression between groups have been distinguished: miR-671-3p, miR374a-5p, miR-1307-5p and miR-708-5p. The relationship between the most frequent miRs' expressions and age has been evaluated and no correlation has been detected. In view of the above, it seems reasonable to examine the influence of miR on the biogenesis of PEX. Further studies on miR-671-3p, miR-374a-5p, miR-1307-5p and miR-708-5p expression in PEX are needed.

RESUMO

BACKGROUND Giant cell arteritis (GCA) is an inflammation of large vessels that affects the lining of the arteries and leads to vessel swelling and the eventual reduction of blood flow. This can result in ischemia of the optic nerve, which is known as arteritic anterior ischemic optic neuropathy (AAION). The present case seems noteworthy because the patient developed GCA with the ocular manifestation of AAION shortly after having COVID-19. CASE REPORT A 69-year-old woman was admitted to the Clinic of Ophthalmology after having COVID-19. She reported vision loss in the left eye, which appeared 2.5 weeks after a positive SARS-CoV-2 test. While in the hospital, she was diagnosed with AAION and GCA. The patient was treated with enoxaparin sodium, prednisone, and methotrexate. Three months after the hospitalization, the visual acuity of the left eye was limited to light perception, and optic nerve atrophy was reported. CONCLUSIONS We would like to emphasize the role of SARS-CoV-2 infection as a possible risk factor for the onset of GCA and its ocular manifestations, such as AAION. However, further research is needed to determine the relationship between SARS-CoV-2 infection and GCA. Because some symptoms of the 2 diseases are similar, the diagnosing process might be long and challenging. The diagnosis of GCA should be made as soon as possible to avoid serious complications, such as bilateral vision loss.
