Described herein is a method for treating or prophylaxis of adverse immune reaction to metal debris, metal induced delayed type hypersensitivity (DTH), or inflammatory osteolysis by attenuating the inflammatory response. In one aspect, the method involves inhibiting the nucleotide-binding domain (NOD)-like receptor protein 3 (NLRP3) inflammasome/caspase-1 pathway or neutralizing or blocking the activity of interleukin 17 (IL-17), IL-17 receptor (IL-17R), IL-1R, IL-1&#x3b2;, IL-18, IL-21, IL-23 with anti-IL-17, anti-IL-17A, anti-IL-17F, anti-IL-17A/F, anti-IL-1, anti-IL-1&#x3b2;, anti-IL-18, anti-IL-21, anti-IL-23, anti-IL-1R, soluble IL-17 receptors, soluble IL-1 receptors, soluble IL-18 receptors, soluble IL-21 receptors, IL-17 receptor inhibitors, IL-1 receptor inhibitors, IL-18 receptor inhibitors, IL-21 receptor inhibitors, IL-23 receptor inhibitors, blocking agents, inflammasome inhibitors, or combinations thereof.

Treatment for adverse immune reaction to metal implant debris

One aspect of the invention provides a method of determining metal ion levels in the patents due to corrosion and wear processes of the metallic implant in a human or veterinary patient. One embodiment provides a cost effective and patient driven early diagnostic method which has a potential application in orthopedics and dentistry. In one embodiment, the method includes the use of an electrochemical biosensor to detect metal ions or particles in a sample taken from a patient having a metallic implant.

Metal-ion electrochemical biosensor and use thereof

A plastic implant device for a mammal that contains a rare earth metal compound tracer and a method for detecting degradation such as wear of the implanted device are disclosed. The tracer can also be present with a separate antioxidant or the tracer compound can be can be the salt of a C-Cunsaturated carboxylic acid. The rare earth metal compound tracer is released when the prosthetic is worn down or otherwise degraded in the mammalian body in which it was implanted. The presence and amount of released tracer present in a body fluid or tissue sample measured and is proportional to the degree of degradation of the implant.
