Several studies have explored the
relationship between fibromyalgia and oxidative stress, others investigated elemental
composition of patients with fibromyalgia, but surveyed only in blood and urine samples.
The latter studies, while potentially useful, overlooked the mineral content of hair. Hair
mineral assay can be an effective method to deduce intracellular status.
The featured study
investigates the elemental characteristics in the hair of women with fibromyalgia, and
compared the data with those from healthy age and body mass matched women and found
distinct mineral differences.
This study evaluated the characteristics of hair minerals in female patients with fibromyalgia
compared with a healthy reference group.
Forty-four female patients diagnosed with
fibromyalgia according to the American College of Rheumatology criteria were enrolled as
the case group. Age and body mass index-matched data were obtained from 122 control
subjects enrolled during visit for a regular health check-up. Hair minerals were analyzed and
compared between the two groups. The mean age was 43.7 yr.
General characteristics were
not different between the two groups. Fibromyalgia patients showed a significantly lower
level of calcium (775 µg/g vs 1,093 µg/g), magnesium (52 µg/g vs 72 µg/g), iron (5.9 µg/g
vs 7.1 µg/g), copper (28.3 µg/g vs 40.2 µg/g) and manganese (140 ng/g vs 190 ng/g).
Calcium, magnesium, iron, and manganese were loaded in the same factor using factor
analysis; the mean of this factor was significantly lower in fibromyalgia group in multivariate
analysis with adjustment for potential confounders.
In conclusion, the concentrations of
calcium, magnesium, iron, and manganese in the hair of female patients with fibromyalgia
are lower than of controls, even after adjustment of potential confounders.
