Simultaneous Subconjunctival Triamcinolone and Bevacizumab Injections for Management of Blepharokeratoconjunctivitis in Children.

ABSTRACT: Purpose:To report the efficacy of subconjunctival triamcinolone (Kenalog A-40, Alcon) and bevacizumab (Avastin, Genentech) injections in fraternal twins with blepharokeratoconjunctivitis (BKC) causing progressive, bilateral corneal neovascularization and scarring. Methods:In this retrospective observational case series, two three-year-old male twins with BKC had presented with bilateral red eyes, photophobia, and frequent blinking. Examination of each child showed bilateral deep stromal and superficial corneal neovascularization, corneal infiltrates, multiple follicles on the palpebral conjunctiva bilaterally with blepharitis, and thick turbid sebum expressed from the Meibomian glands. Their disease progressed despite conventional treatment. Both twins were managed with subconjunctival triamcinolone injection and subconjunctival bevacizumab injection of each eye. Results:The treatment resulted in improvement of symptoms, and examination over an 8-10-month period postinjections showed fading stromal corneal infiltrates, partially regressed corneal neovascularization, and reduced conjunctival injection without complications. Conclusion:This case series highlights the potential vision threatening complications of BKC. In addition to conventional management options, this report is the first published use of subconjunctival triamcinolone and bevacizumab injections for BKC in children in an attempt to minimize and improve corneal neovascularization and scarring and subsequently to retain useful vision.

Project description:ImportanceIntravitreous injections of anti-vascular endothelial growth factor (VEGF) agents are associated with a sustained increase in intraocular pressure. This sustained elevated intraocular pressure could lead to higher rates of glaucoma surgery to lower this pressure.ObjectiveTo determine the risk of glaucoma surgery following repeated intravitreous bevacizumab injections.Design, setting, participantsThis nested, case-control study acquired and analyzed data from large, population-based, linked health databases supported by the British Columbia Ministry of Health in Canada. Study participants included all patients with ophthalmic issues in British Columbia, such as those of the Provincial Retinal Diseases Treatment Program, who had received intravitreous bevacizumab injections for exudative age-related macular degeneration between January 1, 2009, and December 31, 2013. Cases were identified using glaucoma surgical codes for trabeculectomy, complicated trabeculectomy, glaucoma drainage device, and cycloablative procedure. For each case, 10 controls were identified and matched for age, preexisting glaucoma, calendar time, and follow-up time. The number of intravitreous bevacizumab injections received per year-3 or fewer, 4 to 6, or 7 or more-was determined for both cases and controls. Data analysis was performed from February 23, 2016, to November 14, 2016.Main outcomes and measuresRisk of glaucoma surgery compared with the number of intravitreous bevacizumab injections per year in cases and controls. Rate ratios were adjusted for covariates (diabetes mellitus, myocardial infarction, stroke, and verteporfin use).ResultsSeventy-four cases of glaucoma surgery and 740 controls were identified, with a mean (SD) age of 81.3 (8.4) years for cases and 81.4 (7.9) for controls. The case group had more males than the control group (38 [51.4%] vs 272 [36.8%]). The adjusted rate ratio of glaucoma surgery among those who received 7 or more injections per year was 2.48 (95% CI, 1.25-4.93). There was a 10.3% higher number of 7 or more injections among cases compared with controls. The adjusted rate ratio for those who received 4 to 6 injections per year compared with those who received 3 or fewer was 1.65% (95% CI, 0.84-3.23).Conclusions and relevanceFindings from this large, pharmacoepidemiologic study suggest that 7 or more intravitreous injections of bevacizumab annually is associated with a higher risk of glaucoma surgery and that 4 to 6 injections per year show a nonstatistically significant rate ratio in the same direction.

Project description:BackgroundKeloid disease is hard to fully eradicate. Recurrence and other unsatisfactory results were found in many patients. No current therapeutic modality has been determined to be most effective for treating keloid scars. Intralesional corticosteroid injections is most commonly recommended for primary management of small and young keloids as well as hypertrophic scars. However, it's difficult for patients to adhere to long-term triamcinolone acetonide injection therapy because of the pain, inconvenience or complications including hormonal imbalance or irregular menstruation.ObjectiveWe aimed to determine whether and how Strontium-90 brachytherapy as an adjuvant radiation could affect keloid recurrence after intralesional triamcinolone and 5-fluorouracil injections.MethodsWe included keloid patients from March 2019 to September 2019 and randomly allocated them to two groups after 3 intralesional triamcinolone and 5-fluorouracil injections at 3 weeks interval. The experimental group received Strontium-90 brachytherapy at a total dose of 15-20Gy, while the control group didn't receive any adjuvant treatment. We performed both Vancouver Scar Scale scoring and Color Doppler ultrasound examination to monitor and evaluate lesions regularly. A one-year follow-up was completed for each patient.Results31 patients who had 42 keloids in total were recruited. We found intralesional triamcinolone and 5-fluorouracil injections could effectively reduce the thickness and modify the hardness of small and young keloids. Strontium-90 brachytherapy reduced the one-year recurrence rate from 85.7 percent to 44.4 percent after 3 intralesional triamcinolone and 5-fluorouracil injections. The lesions' thickness or elasticity was not affected by Strontium-90 brachytherapy.ConclusionStrontium-90 brachytherapy as an adjuvant radiation could effectively reduce small sized keloids recurrence after intralesional triamcinolone and 5-fluorouracil injections. It worked by enhancing the lesions' stability post-injection.Trial registrationThe clinical trial registration number: ChiCTR2000030141. Name of trial registry: Chinese Clinical Trial Registry (http://www.chictr.org.cn/).
