Aim To assess plasma zinc and copper levels in individuals with anxiety and to test the hypothesis that there is a relationship between copper and zinc concentration and improved symptoms. Subjects and Methods Serum from 38 individuals with anxiety and 16 neurotypical age, gender and size similar controls were tested for plasma zinc and copper concentration using inductively-coupled plasma-mass spectrometry. Zinc and copper levels, pre and post therapy, were compared and assessed for perceived anxiety symptoms. Results In this preliminary study, individuals with anxiety had significantly higher plasma levels of Cu ( P = 0.0348), Cu/Zn ( P = 0.0493) and lower Zn ( P = 0.0294) compared to controls. Zn levels normalized (increased to the normal range) and Cu/Zn significantly decreased after zinc therapy ( P = 0.0004, P = 0.0033, respectively), but Cu did not significantly decrease (0.3577). These same patients improved significantly with respect to perceived overall symptoms after zinc and anti-oxidant therapy ( P = 0.013). Discussion These results suggest an association between Zn plasma levels and individuals with anxiety, demonstrate that zinc therapy is effective in increasing zinc plasma levels, and show that zinc supplementation may play a role in improved symptoms.

Aim To assess plasma Zn and Cu levels in individuals with depression. Subjects and Methods Plasma from 73 clinically depressed individuals, 38 individuals with anxiety and 16 controls were tested for plasma Zn and Cu concentration using inductively-coupled plasma-mass spectrometry. Results Depressed individuals, with and without secondary anxiety, had decreased plasma Zn and elevated plasma Cu compared to controls. Zn normalized (increased to the level of normal controls) but Cu increased in individuals with depression (with and without secondary anxiety), after Zn therapy, whereas both plasma Zn increased and Cu levels decreased in anxiety, with and without secondary depression, after Zn therapy. Individuals with depression, with and without secondary anxiety, had significantly higher symptom severity when compared to neurotypical controls. Symptom severity in individuals with anxiety (both with and without secondary depression) significantly decreased after Zn therapy, whereas symptoms remained the same in individuals with primary depression. Discussion These data show an association between Zn and Cu plasma levels and clinically depressed individuals, and suggest that high Cu levels are associated with high symptom severity.

Aim To assess plasma zinc and copper concentration in individuals with autism. Subjects and Methods Plasma from 79 autistic individuals, and 18 age and gender similar neurotypical controls, were tested for plasma zinc and copper using inductively-coupled plasma-mass spectrometry. Results Autistic individuals had significantly elevated plasma levels of copper and Cu/Zn and lower, but not significantly lower, plasma Zn compared to neurotypical controls. Zn levels increased significantly in autistic individuals with and without GI disease after zinc therapy. Cu decreased significantly after zinc therapy in the GI disease group but not in the autistic group without GI disease. Autistic children significantly improved with respect to hyperactivity and stimming after zinc therapy in autistic children with GI disease. Autistic children without GI disease did not improve in these symptoms after the same therapy. Discussion These results suggest an association between zinc and copper plasma levels and autism, and they suggest that zinc therapy may be most effective at lowering copper levels in autistic children with GI disease.

Aim To assess serum HGF concentration in individuals with schizophrenia and investigate the efficacy of zinc and B-6 therapy on these levels. Subjects and methods Serum from 18 individuals diagnosed with schizophrenia and 19 age and gender similar controls ( P = 0.18) were tested for HGF concentration using ELISAs, and tested for copper and zinc plasma levels using inductively-coupled plasma-mass spectrometry. Results HGF serum levels of individuals with schizophrenia, before zinc and B-6 therapy, were significantly lower than age and gender similar controls ( P = 0.016), and significantly lower in schizophrenia patients pre-therapy compared to post therapy ( P = 0.028). HGF levels normalized (reached levels similar to controls) post-therapy. Zinc levels in these same individuals also normalized, and perceived symptoms, particularly anxiety ( P = 0.03), improved significantly after therapy. Discussion These results suggest an association between low HGF levels and schizophrenia and demonstrate that zinc and B-6 therapy may be associated with the normalization of HGF levels and perceived improvement in symptoms.

Copper And Zinc

Aim To assess plasma zinc and copper concentration in individuals with autism and correlate these levels with symptom severity. Subjects and Methods Plasma from 102 autistic individuals, and 18 neurotypical controls, were tested for plasma zinc and copper using inductively-coupled plasma-mass spectrometry. Copper and zinc levels and Cu/Zn were analyzed for possible correlation with severity of 19 symptoms. Results Autistic individuals had elevated plasma levels of copper and Cu/Zn and lower, but not significantly lower, plasma Zn compared to neurotypical controls. There was a correlation between Cu/Zn and expressive language, receptive language, focus attention, hyperactivity, fine motor skills, gross motor skills and Tip Toeing. There was a negative correlation between plasma zinc concentration and hyperactivity, and fine motor skills severity. Discussion These results suggest an association between plasma Cu/Zn and severity of symptoms associated with autism.
