Jarisch–Herxheimer reactions can be life-threatening because they can cause a significant drop in blood pressure and cause acute end-organ injury, eventually leading to multi-organ failure.[1]
Prophylaxis and treatment with an anti-inflammatory agent may stop progression of the reaction. Oral aspirin or ibuprofen every four hours for a day or 60 mg of prednisone orally or intravenously has been used as an adjunctive treatment [citation needed]. However, steroids are generally of no benefit. Patients must be closely monitored for the potential complications (collapse and shock) and may require IV fluids to maintain adequate blood pressure. If available, meptazinol, an opioid analgesic of the mixed agonist/antagonist type, should be administered to reduce the severity of the reaction. Anti TNF-α may also be effective.[7][8]
History
Both Adolf Jarisch,[9] an Austrian dermatologist, and Karl Herxheimer,[10] a German dermatologist, are credited with the discovery of the Jarisch–Herxheimer reaction. Both Jarisch and Herxheimer observed reactions in patients with syphilis treated with mercury. The reaction was first seen following treatment in early and later stages of syphilis treated with Salvarsan, mercury, or antibiotics. Jarisch thought that the reaction was caused by a toxin released from the dying spirochetes.[11]
