bummer, no full text for me. who's got a subscription to this article?Blood Plasma Levels of Microelements in Patients with History of Optic Neuritis (2013)
http://journals.sagepub.com/doi/abs/10. ... 8516642315
Purpose: To determine the concentration of microelements in the blood of patients with a history of retrobulbar optic neuritis (ON).
Materials and methods: We examined 36 patients (18–63 years of age) – 11 with demyelinating ON (Group 1) and 25 with isolated ON (Group 2) – all of whom had been treated for retrobulbar ON. The control group comprised 38 healthy volunteers. Using atomic absorption spectroscopy, blood levels of zinc (Zn), iron (Fe), copper (Cu) and cadmium (Cd) were evaluated.
Results: Compared with the control group, concentrations of Cd were elevated in Groups 1 and 2 (p = 0.003 and p = 0.003, respectively); Group 1 had higher levels of Cu (p = 0.02). Patients from both groups had significantly lower levels of Fe (p = 0.0003) compared with controls. No difference in the concentration of any of the microelements was found between Groups 1 and 2.
Conclusion: Disturbances in Cd, Cu and Fe homeostasis may be associated with the inflammatory process of ON.
at least what we can draw from this abstract is that the patients had a higher copper zinc ratio than controls.
re high cadmium, that is so similar to zinc that it is toxic by virtue of occupying (effectively blocking) zinc receptors in your body.
i'm so curious about the serum levels
take home message from the abstract, even though this is a small n single study, if optic neuritis is part of your world, could be wise to optimize your ferritin, copper, and copper zinc ratio
and stop or moderate whatever you're doing to increase cadmium retention.
excellent sentence:
Nutritional optic neuropathies

"Nutritional deficits are often associated with toxic effects from alcohol and tobacco; therefore, the separation of the nutritional and toxic components is often illusory and artificial."
