Comment on: Chronic fatigue syndrome. A fresh look at an old problem. [Can Fam Physician. 1993]
There are some unfortunate inaccuracies in the article “Chronic Fatigue Syndrome.”‘ While the general information is useful in a very basic sense, two of the so-called “fresh look” items are inaccurate and misleading.
First, Dr McSherry suggests that “Oral magnesium supplements are indicated for CFS patients with subnormal red blood cell magnesium levels….” Presumably this recommendation comes from Dr McSherry’s reference to the study done by Cox et al. In this paper, red blood cell magnesium levels were found to be lower in patients diagnosed with chronic fatigue syndrome (CFS) than in a matched normal group, and patients were found to improve with intramuscular injections of 50% magnesium sulphate (1 g in 2 mL) every week for 6 weeks. However, oral magnesium has not been tested for its effectiveness in patients with CFS. Dr McSherry’s recommendation to use oral magnesium is, therefore, inaccurate and misleading.
