Dear Sir, Evengård et al.’s article [1] on chronic fatigue syndrome (CFS) is disappointing, because in their review, despite its 15 pages and 165 references, there is not a single word about the staggering similarity between CFS and Addison’s disease. As someone whose CFS symptoms resolved dramatically with an old remedy for Addison’s disease [2], I understandably found that review even more disappointing.
To compensate for Evengård et al.’s failure to mention both the impressive overlap of CFS with Addison’s disease and its clinical implications, I summarize here these issues.
CFS and Addison’s disease share 36 features [3–6]. Three others, however, are to be added. In fact, reduction in adrenal gland size [7], antibodies against the adrenal gland [8] and respiratory muscle dysfunction [9], besides being present in CFS [7–9], have also been found in Addison’s disease [10–12]. In view of the 39 features that CFS shares with Addison’s disease [3–12] (see Table 1), which constitute a similarity between two distinctly named diseases that is probably unequalled in the medical literature, it seems arguable that CFS should practically be viewed as a form of Addison’s disease [13]. One could object that CFS patients, unlike Addisonian subjects, do not display hyperpigmentation or basal hypocortisolaemia. Neither abnormality, however, is a constant presenting feature of Addison’s disease [14].
