RESUMEN
The discovery of antivascular endothelial growth factor medications has resulted in a substantial change in diabetic retinopathy treatment. The most common cause of diabetic retinopathy blindness is Diabetic Macular Edema. The pathophysiology of Diabetic Macular Edema is thought to include the well-known pro-angiogenic and pro-permeability factor vascular endothelial growth factor. Over the past decade, drugs that impede the functions of vascular endothelial growth factors have established themselves as a standard-of-care treatment for a range of ocular ailments and improved patients' clinical results with diabetic retinopathy and Diabetic Macular Edema, and their frequency has grown exponentially with the introduction of these agents Pegaptanib, Ranibizumab, and Aflibercept which are approved for ophthalmic indications, while Bevacizumab is used off-label. These medications delivered intravitreally have halted the vascular development of diabetic retinopathy. Various randomized trials have proven that antivascular endothelial growth factor medication is safe and effective in preserving vision. Following an extensive period of preclinical development aimed at enhancing and defining its biological impacts, these drugs were shown in clinical trials to be effective in treating diabetic retinopathy and other ophthalmic conditions. Data from various sources suggest that Pegaptanib, Ranibizumab, and Aflibercept are costly, while Bevacizumab is cost-effective, and in low and middle-income nations, it is thus a desirable therapy choice. However, issues with compounding, counterfeiting, and off-label usage restrict its availability in many nations. The pharmacology, pharmacokinetics, pharmacodynamics, adverse effects, and contraindications of antivascular endothelial growth factor agents are discussed, and the results of clinical trials evaluating their efficacy are summarized.
RESUMEN
Cerebral malaria is the most severe and rapidly fatal neurological complication of Plasmodium falciparum infection and responsible for more than two million deaths annually. The current therapy is inadequate in terms of reducing mortality or post-treatment symptoms such as neurological and cognitive deficits. The pathophysiology of cerebral malaria is quite complex and offers a variety of targets which remain to be exploited for better therapeutic outcome. The present review discusses on the pathophysiology of cerebral malaria with particular emphasis on scope and promises of curcumin as an adjunctive therapy to improve survival and overcome neurological deficits.
