AMD is becoming one of the leading causes of blindness in older adults. The prevalence rate of the wet form of AMD has been increasing due to the lack of selective therapeutic modalities. Current therapeutic interventions such as drugs targeting VEGF, and VEGF receptors, laser coagulants delivered unsuccessful clinical outcomes in AMD patients. Hence, the cost-effective anti-oxidant therapeutic interventions like molecular hydrogen to protect retinal pigment epithelium (RPE) by mitigating oxidative stress may deliver effective clinical outcomes in AMD patients.
Female patients with late-stage AMD of age above 70 years were chosen for this case report. The patients were administered QIAPI1©, a melanin precursor via sublingual route and the photographs were obtained for left and right eye to depict the efficacy of QIAPI1© against the wet form of AMD.
The administration of QIAPI1© extensively mitigated yellow-colored drusen accumulations in the retina, retinal edema, exudates, and hemorrhages in the right eye, but the effect was minimal in the case of left eye; the overall drusen accumulation was lesser than the first consultation.
Current case report has concluded the intrinsic effect of melanin in producing the molecular hydrogen and chemical energy across the retinal tissues by dissociating water molecules and dissipating the drusen accumulations, retinal edema, and hemorrhages in AMD patients. Our preliminary study reported the usage of QIAPI1© as a prospective therapeutic modality to mitigate the oxidative stress-mediated pathophysiology of the wet form of AMD.
年龄相关性黄斑变性(AMD)正成为老年人失明的主要原因之一。由于缺乏选择性治疗方式,湿性AMD的患病率一直在上升。目前的治疗干预措施,如靶向血管内皮生长因子(VEGF)及其受体的药物、激光凝固剂,在AMD患者中未取得成功的临床效果。因此,像分子氢这样具有成本效益的抗氧化治疗干预措施,通过减轻氧化应激来保护视网膜色素上皮(RPE),可能会在AMD患者中产生有效的临床效果。
本病例报告选取了70岁以上晚期AMD女性患者。通过舌下途径给患者服用黑色素前体QIAPI1©,并拍摄左右眼照片以描述QIAPI1©对湿性AMD的疗效。
服用QIAPI1©可广泛减轻右眼视网膜中黄色玻璃膜疣的积聚、视网膜水肿、渗出物和出血,但左眼的效果甚微;总体玻璃膜疣积聚少于首次会诊时。
本病例报告得出结论,黑色素通过解离水分子在视网膜组织中产生分子氢和化学能,从而消除AMD患者的玻璃膜疣积聚、视网膜水肿和出血,具有内在作用。我们的初步研究报告了QIAPI1©作为一种前瞻性治疗方式的应用,以减轻湿性AMD氧化应激介导的病理生理过程。
