“…Because in our previous study on diabetic adults (without CP) we found significant differences in LCPUFA status [14], we excluded patients with diabetes from the present study. Hence, our present data may be evaluated in parallel with the data of Quilliot et al [13] on their patients with CP but without diabetes.…”

“…In addition to hyperglycemic conditions, the alteration in retinal fatty acid metabolism, possibly via AGE/RAGE interactions and the activation of the MAPK pathway, can lead to chronic inflammation due to a decrease in retinal n-3 polyunsaturated fatty acids (PUFAs), such as docosohexanoic acid (DHA) [121]. Moreover, the increase in n6 essential fatty acid (EFA) levels, such as with linoleic acid in diabetes, may stimulate inflammation in the diabetic retina [122, 123]. In addition to its possible role in dyslipidemia, AGE/RAGE interactions may lead to vascular endothelial cell activation, upregulation of ICAM-1 and E-selectin expression, and increased leukostasis [124].…”

Diabetic retinopathy (DR) remains a major complication of diabetes and a leading cause of blindness among adults worldwide. DR is a progressive disease affecting both type I and type II diabetic patients at any stage of the disease, and targets the retinal microvasculature. DR results from multiple biochemical, molecular and pathophysiological changes to the retinal vasculature, which affect both microcirculatory functions and ultimately photoreceptor function. Several neural, endothelial, and support cell (e.g., pericyte) mechanisms are altered in a pathological fashion in the hyperglycemic environment during diabetes that can disturb important cell surface components in the vasculature producing the features of progressive DR pathophysiology. These include loss of the glycocalyx, blood-retinal barrier dysfunction, increased expression of inflammatory cell markers and adhesion of blood leukocytes and platelets. Included in this review is a discussion of modifications that occur at or near the surface of the retinal vascular endothelial cells, and the consequences of these alterations on the integrity of the retina.
“…One candidate that could improve treatment success may be longer chain ω-3 polyunsaturated fatty acids (PUFAs) from fatty fish, including eicosapentaenoic acid (EPA; C20:5 ω-3) and docosahexaenoic acid (DHA; C22:6 ω-3) (Pouwer et al, 2005). Both depressed patients and diabetic patients are known to have relatively low levels of ω-3 PUFAs (Decsi et al, 2007;Sontrop and Campbell, 2006;Vessby, 2000). A recent meta-analysis showed that ω-3 PUFAs were efficacious as antidepressant therapy (Appleton et al, 2010) , although heterogeneity in study design was noted.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
