Basic MEA notes on steroids and ME/CFS:
Points to note regarding the use of steroid drugs and ME/CFS:
1 Steroids are drugs that have what is called an immunosuppressive action - so they are sometimes used to dampen down inflammatory responses in conditions like asthma, arthritis, inflammatory bowel disease/crohn's disease - where they can be a very effective form of treatment
2 Research into immune system dysfunction in ME/CFS indicates that this may involve an on-going inflammatory response by the immune system, including the production of immune system chemicals called cytokines, to a triggering infection.
3 There is also a problem with the hormonal axis (hypothalamic-pituitary-adrenal axis) that controls the release of cortisol from the adrenal glands and this may be lowered in ME/CFS = hypocortisolaemia
4 So there are two theoretical reasons why the use of steroids might actually be beneficial in treating ME/CFS
However, no proper clinical trials have ever been carried out involving higher dose steroids and anecdotal reports (including a small two month trial in Glasgow some years ago) suggest that steroids such as predisolone are not of any overall benefit in ME/CFS
5 There have been some trials using much lower doses of steroids (=hydrocortisone) but the results here suggest that the potential longer term problems outweigh any possible short term benefits. These trials are summarised and referenced in the Treatment section of the MEA purple book:

6 Steroids, especially at higher doses, can have a number of side effects - short term and longer term
Some of these are similar to symptoms found in ME/CFS. So people with ME/CFS who are using steroids for another medical condition may find that some of their ME/CFS symptoms are made worse
7 Steroid side-effects can include:
muscle weakness
increased risk of infections
insomnia
nausea
headaches
malaise
vertigo
Long term use can cause muscle wasting, diabetes and osteoporosis
8 Side effects are minimised by using the lowest possible dose for the shortest possible period
9 Steroids are also sometimes given by injection for joint, muscular and soft tissue problems/injuries - this would not normally involve a high dose over a prolonged period of time and feedback from people with ME/CFS who have had this type of treatment does not indicate that it causes any significant problems in relation to ME/CFS.
10 In our current state of knowledge, and taking into account all of the above information covering pros and cons, most doctors, myself included, take the view that steroids should not be used to treat ME/CFS
