(JWissmille) Date: 1998/02/13 source: Lyme Disease 1991: Patient/Physician Perspectives from the U.S. and Canada--- Lora Mermin, editor Antibiotics and Steroids by Drulle, M.D. " Corticosteroids, or steroids as they are commonly called, are very important drugs in a wide variety of medical conditions. They exert an anti-inflammatory effect and suppress the immune system. This may be life saving in some diseases such as asthma and malignancies. On the other hand, steroids are rarely curative, and are associated with harmful side effects if used for prolonged periods of time. These include bone loss, cataracts, sodium retention, weight gain, abnormal fat distribution and predisposition in other infections. " The use of steroids in infectious diseases has always been controversial. It is well known that steroids can reactivate dormant tuberculosis infections. Recent studies have shown that in meningitis infections steroids may decrease the incidence of post infectious complications. However, in cases of septic shock, their ability to improve survival rates is dubious. We have been traditionaly taught that in bacterial infections an intact, well-functioning immune system is necessary in order to recover. Steroids in the face of bacterial infections may alter the prognosis and in tuberculosis may actually increase the risk of fatality. " Since Lyme is a bacterial infection, the question naturally arises as to what is the role of steroids in Lyme disease. Before the bacterial nature of Lyme was discovered, it was common to treat the arthritis complications and heart blocks with steroids. Early reports suggested that the heart blocks responded well to the steroids. However, in one report dealing with patients with Lyme arthritis, steroid injections into the joints prior to antibiotic therapy were associated with a worse prognosis when antibiotics were finally given. We have seen literally dozens of patients with Lyme who were initially treated with steroids who reported a dramatic worsening rather than improvement as would be expected. Dr. ph Burrascano has coined the expression, ' Steroid Disasters, ' to describe these patients. " It is interesting to note that in dogs who had Lyme disease, injections of dexamethasone, a corticosteroid, enabled Borrelia burgdorferi to be cultured from blood drawn on the following day. This was done by Dr. Burgess at the University of Wisconsin. This suggests that the steroid suppresses a mechanism for keeping the bacteria out of the circulatory system, since ordinarily it is difficult to grow the Lyme organism from the blood. Entrance of the bacteria into the bloodstream can allow seeding of other organs. " I have used steroids in Lyme patients, but only in very selected circumstances. In patients who have presented with eye involvement with rapidly deteriorating vision, such as optic neuritis or uveitis, the combination of high dose steroids appears to restore vision more rapidly than by using antibiotics alone. I have also used steroids in combination with antibiotics in patients who presented with a Lyme induced polymyalgia rheumatica (PMR). " PMR is a common disease of elderly people characterized by pain and stiffness in the muscles of the upper arms and legs, fevers, malaise and weight loss. The ESR, sedimentation rate is elevated. In its classic form, the cause of the condition is unknown, and the dramatic response to steroids is in itself diagnostic. I have personally seen three cases of Lyme induced PMR, which did not respond to steroids alone or antibiotics alone, yet when the combination was given the response was dramatic. " In conclusion, the decision to use the steroids in a Lyme patient must be given considerable thought and the possible benefits must be weighed against the risks. I would not use steroids unless the patient was also on antibiotics. " source: When to Suspect Lyme Disease by D. Bleiweiss, M.D. " ....I routinely advise my patients with LD to abstain from cigarettes, alcohol and steroids because therapeutic inadequacy or an avoidably prolonged convalescence is frequent (Dattwyler, RJ, Lancet 1:687, 1987 - on steroid use). Patients have described clinical deterioration when steroids were used fortuitously or intentionally when hypoadrenalism was absent. Another hazard attending palliative steroid use is that some symptoms will be concealed, rendering the clinical picture less interpretable. In a privatecommunication, a physician reelated that one of his LD patients succumbed to fatal cardiomyopathy after receiving steroids. One helpful caveat is to avoid the use of electric blankets or sleeping in water beds with the electric current activated, otherwise you might wake up with one or more LD symptoms. Allergic and chemical hypersensitivities can enhance or cause symptoms to emerge temporarily..... " WHEN TO SUSPECT LYME DISEASE D.

" from dejanews archives: There are a host of immunosuppressive drugs knocking about and they fall into 5 broad categories: 1. Non-steroidal antiinflammatory drugs (NSAIDS) 2. Steroids 3. Drugs which are immunosuppressive by virtue of a side effect. 4. Cyclosporin 5. Cytotoxins 1. NSAIDS 1. Salicylic acids Includes aspirin and benylorate 2. Propionic acids Includes ibuprofen, naproxen, ketoprofen and flurbiprofen 3. Acetic acids Includes indomethacin 4. Fenamates 5. Oxicams Includes piroxicam 6. Pyralazones 7. Paracetamol 8. Tolmetin The NSAIDS have varining capacities to suppress the main inflammatory events (increased core temperature, pain and the inflammatory reaction). Many of them work by inhibiting cyclooxygenase which is enzyme which catalyses the conversion of arachidonic acid to prosta- glandins and thromboxanes. In the main, this inhibition is competitive that is, the drug molecule competes for the active site on the enzyme and prevents arachidonate from binding and being converted to prost- aglandins. The notable exception is paracetamol which is thought to operate by scavenging free-radicals required for the peroxidase activity of the cyclooxygenase enzyme complex. 2. Steroids There are two main classes of adrenal steroid. 1. Mineralocorticoids 2. Glucocorticoids Mineralocorticoids have no antiinflammatory effects, but glucocort- icoids have both antiinflammatory and certain mineralocorticoid activity. One of the most frequently encountered glucorticoids is dexamethasone. The drug acts by inhibition the production of the key inflammatory mediator interleukin-1. The net effect is a very generalized suppression of the acute inflammatory response. 3. Side effect actions Can anyone fill this in for me? The lassie mentioned alcohol. Is this true? Certainly, tricyclic antidepressants have no such activity. 4. Cyclosporin Fungal peptide which selectively acts on lymphocytes. The drug is used frequently in organ transplantation and has effects mainly in the longer term activity of the immune system (ie. it is no good for a headache but is great for preventing organ rejection). The mechan- ism of action is complex but involves the inhibition of the action of a key immune mediator called interleukin-2 5. Cytotoxins Cytotoxins work on the basis of " let's zap every cell in the body and pray that the guy survives but that his immune system doesn't " . This approach is similar to cancer chemotherapy but there you hope that the guy survives and the tumour doesn't. The drugs include azathioprine, cyclophosphamide and chlorambucil. They have effects on the proliferation of lymphocytes, the cellular mediators of immunity and inflammation. Apologies in advance if I have over-simplified anything, said anything wrong or forgotten to mention someones pet drug. I also refute any allegations of having connections with any pharmaceutical firms who may or may not have taken my Dad to the Hotel de Paris in Monte-Carlo. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Nigel C.
