Effect of an (-)-Epicatechin Intake on Cardiometabolic Parameters-A Systematic Review of Randomized Controlled Trials.

Growing evidence exists that consumption of cocoa-rich food improves the parameters of cardiometabolic health. These effects are ascribed to cocoa flavanols, particularly to (-)-epicatechin (EC), a natural ingredient of cocoa. Hence, to evaluate if EC may explain the effects of cocoa, this systematic review aimed to provide an overview on randomized controlled trials (RCTs) investigating the impact of an EC intake on cardiometabolic biomarkers. For this, the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 statement was considered and the risk of bias (RoB) was assessed by using the Cochrane RoB 2 tool. In total, 11 studies were included examining parameters on vascular function, glucose/lipid metabolism, oxidative stress, inflammation, appetite sensations, and body weight before and after EC treatment. Except for a dose-dependent acute increase in flow-mediated dilatation (FMD) and in the peripheral arterial tonometry (PAT) index in healthy young adults, effects by EC treatment were not observed. For most trials, some concerns exist for overall RoB. Thus, EC intake may improve endothelial function in healthy young adults. For further parameters (mostly secondary outcomes), it remains unclear if EC has no effect or if this was not detectable. Unbiased RCTs on the impact of an EC intake are needed, which should also investigate the additive or synergistic effects of EC with other cocoa ingredients.

Intravitreal bevacizumab for treatment of neovascular age-related macular degeneration: a one-year prospective study.

PURPOSE: To investigate the efficacy of intravitreal bevacizumab for treatment of neovascular age-related macular degeneration (AMD). DESIGN: Prospective, open-label, nonrandomized clinical study. METHODS: Sixty patients (60 eyes) with subfoveal choroidal neovascular membrane (CNV) attributable to AMD participated in this study at the American University of Beirut and Hotel Dieu de France Retina Clinics. All lesion types were included except for retinal angiomatous proliferation. In the initial treatment phase, intravitreal bevacizumab (2.5 mg/0.1 ml) was given at baseline, and then two additional monthly injections were given if the macula was not dry on optical coherence tomography. The criteria for re-injection after the induction phase were presence of new fluid in the macula, increased central retinal thickness (CRT) at least 100 microm, loss of at least five letters of vision with increased fluid in the macula, new classic CNV or new macular hemorrhages. Main outcome measure was the proportion of eyes losing <15 letters of vision after 12 months. RESULTS: Fifty-one patients (51 eyes) completed the 12 months. Mean visual acuity improved from 45.7 letters at baseline to 53.1 letters at 12 months (P = .004), and 47 eyes (92.2%) lost <15 letters. Mean CRT decreased from 327.4 microm at baseline to 227.8 microm at 12 months (P < .001). A mean of 3.4 injections were given over the course of the study, and no ocular or systemic side-effects were noted. CONCLUSION: Eyes with neovascular AMD treated with intravitreal bevacizumab over 12 months had significant anatomical and functional improvement. Further studies need to confirm the long-term efficacy of this treatment.

Intravitreal bevacizumab for the management of choroidal neovascularization in age-related macular degeneration.

PURPOSE: To investigate the efficacy and safety of intravitreal bevacizumab for managing choroidal neovascularization (CNV) due to age-related macular degeneration (AMD). DESIGN: Prospective interventional case series. METHODS: Seventeen eyes of 17 patients with subfoveal CNV due to AMD participated in this study at the American University of Beirut Ophthalmology Clinics. All patients had failed, refused, or were not eligible for photodynamic therapy. All eyes received a baseline eye examination, which included best-corrected visual acuity (BCVA), dilated fundus examination, ocular coherence tomography (OCT) imaging, and fluorescein angiography. An intravitreal injection of bevacizumab (2.5 mg/0.1 ml) was given at baseline and followed by two additional injections at four-week intervals. BCVA, OCT, and fluorescein angiography were repeated four weeks after each injection. Main outcome measures were improvement in BCVA and central retinal thickness (CRT). RESULTS: Mean baseline BCVA was 20/252 (median 20/200), and baseline CRT was 362 microm (median 350 microm). Improvement in VA and CRT occurred by the fourth week. At 12 weeks, mean BCVA was 20/76 (P < .001) and median BCVA was 20/50 (P < .001). Both mean and median CRT decreased to 211 microm (P < .001). Thirteen (76%) of 17 eyes had total resolution of subretinal fluid, and four eyes (24%) had BCVA better than 20/50. No systemic or ocular side effects were noted at any time. CONCLUSION: Eyes with CNV due to AMD treated with intravitreal bevacizumab had marked anatomic and visual improvement. Further studies are necessary to confirm the long-term efficacy and safety of this treatment.

Infectious uveitis in Virginia.

PURPOSE: To report the causes, clinical features, and outcomes of infectious uveitis in patients managed in a mid-Atlantic tertiary care center. METHODS: Retrospective, observational study of infectious uveitis patients seen at the University of Virginia from 1984 to 2014. RESULTS: Seventy-seven of 491 patients (15.7%) were diagnosed with infectious uveitis (mean age 58 years, 71.4% female, 76.6% Caucasian). The mean follow-up was 5 years. Anterior uveitis was the most common anatomic classification (39 patients, 50.6%) followed by panuveitis (20 patients, 26.0%) and posterior uveitis (18 patients, 23.4%). The most common infectious etiology was herpetic anterior uveitis (37 patients, 48.1%) followed by toxoplasma uveitis (14 patients, 18.2%). The most prevalent viral pathogen was varicella-zoster virus (21 patients, 27.3%) followed by herpes simplex virus (20 patients, 26.0%). Acute retinal necrosis (ARN) was diagnosed in 14 patients (18.2%). Aqueous humor yielded an etiologic diagnosis in seven (50%) of ARN patients, four of whom tested positive for cytomegalovirus and three for varicella-zoster virus. On presentation, 43 patients (55.8%) had a visual acuity (VA) better than 20/40 and 17 (22.1%) had a VA worse than 20/200. VA at the final follow-up was better than 20/40 in 39 patients (50.6%) and worse than 20/200 in 22 patients (28.6%). In all, 16 (20.8%) and 10 (13.0%) patients required cataract and vitrectomy surgery, respectively. A total of 14 patients (18.2%) were on glaucoma topical treatment and four (5.2%) required glaucoma surgery. CONCLUSION: The most common type of infectious uveitis seen over the study period was herpetic anterior uveitis secondary to varicella-zoster virus or herpes simplex virus, found to be most prevalent in patients over 60 years of age. This finding is comparable to other American epidemiologic studies. Ocular toxoplasmosis and ARN were also common causes of infectious uveitis. In all, 50.6% of patients had a VA better than 20/40 at the final follow-up visit, indicating the importance of prompt referral and appropriate treatment.

Double trouble: a patient with both HLA-B27 anterior uveitis and HLA-A29 birdshot chorioretinitis.

BACKGROUND: Birdshot chorioretinitis (BSCR) is a rare ocular inflammatory disorder associated with HLA-A29 and characterized by bilateral choroidal lesions, vitritis, macular edema, and retinal vasculitis. Ocular inflammation associated with HLA-B27 is typically a recurrent, unilateral, acute anterior uveitis (AAU) that is frequently associated with ankylosing spondylitis (AS). To date, there are no reports of patients with both HLA-A29-positive BSCR and HLA-B27 AAU/AS in the English literature. FINDINGS: A 50-year-old man with a history of bilateral anterior uveitis, vitritis, retinal vasculitis, and cream-colored depigmented oval choroidal lesions was found to be HLA-A29 and HLA-B27 positive. His lumbar spine and sacroiliac joint films revealed fusion of the spine, known as 'bamboo spine' compatible with the diagnosis of ankylosing spondyloarthropathy. He had chronic ocular inflammation that was difficult to control with systemic steroids and immunomodulatory agents. CONCLUSIONS: This is the only report of a patient with both HLA-A29-positive BSCR and HLA-B27-positive AS and associated anterior uveitis. The severity of his disease suggests that patients who test positive for both HLA-A29 and HLA-B27 carry a poor visual prognosis. Prompt diagnosis and treatment with local or systemic corticosteroids or steroid-sparing agents may control the disease.

Intravitreal bevacizumab for treatment of neovascular age-related macular degeneration: the second year of a prospective study.

PURPOSE: To demonstrate the efficacy of intravitreal bevacizumab for treatment of neovascular age-related macular degeneration (AMD). DESIGN: Prospective, open-label, nonrandomized clinical study. METHODS: Fifty-one patients (51 eyes) with subfoveal choroidal neovascularization (CNV) resulting from AMD participated in this study at the American University of Beirut and Hotel Dieu de France Retina Clinics. These patients had already completed 12 months of follow-up. The criteria for reinjection were presence of fluid in the macula, increased central retinal thickness (CRT) of at least 100 microm, loss of at least 5 letters of vision associated with increased fluid in the macula, new classic CNV, or new macular hemorrhage. The main outcome measure was the proportion of eyes losing fewer than 15 letters of vision after 12 months. RESULTS: Fifty-one patients (51 eyes) completed the additional 12 months. Mean visual acuity improved from 45.7 letters at baseline to 54.3 letters at 24 months (P = .001), and 47 eyes (92.2%) lost fewer than 15 letters. Mean CRT decreased from 327.4 microm at baseline to 246.6 mum at 24 months (P < .001). A mean of 1.5 injections were administered over the course of the second year. No serious ocular or systemic side effects were noted. CONCLUSIONS: Eyes with neovascular AMD treated with intravitreal bevacizumab over 2 years had significant anatomic and functional improvement compared with baseline. Further studies are necessary to confirm the long-term efficacy and safety of this treatment.
