The results of a MELISA test came back negative for a titanium allergy but revealed Peters is allergic to nickel. Have 79 year-old man with left knee replacement two years ago. There are very few reports on hypersensitivity reactions in association with titaniumbased materials so that the existence of allergy to titanium is still put in question. Mnchen, Germany. The commercially licensed, in vitro lymphocyte transformation test for detecting sensitivity to metals (LTT-MELISA) is not FDA approved and generally is not covered by insurance (1,2). We wanted to highlight the remarkable case of Dana Jeske, a mechanical engineer living near Seattle, who experienced intermittent paralysis for five years, before regaining his ability to walk and move his body normally after he had all metal implants taken out of his body and teeth.

This case highlights the variable presentation of titanium allergy that clinicians should be vigilant for. Many will have seen the devastating news that singer Celine Dion has been diagnosed with Stiff Person Syndrome. The symptoms were so severe that they interfered with the mans lifestyle. Do patients with implants exhibit elevated lymphocyte reactivity to metals and is this reactivity more generalized or more implant-alloy specific? We describe a case of chronic abdominal pain, which is potentially complicated by retained titanium surgical clips and subsequently a retained portion of a pigtail catheter. Preoperative testing may identify preexisting sensitivity but does not predict likelihood of joint failure and may help with selection of type of implant;

Titanium is a transition metal and thus may function as a hapten and trigger cellular hypersensitivity. 81-B, no. Is there any validity to Lymphocyte Transformation testing (LTT) and/or Metal ION testing? Was the patch test removed at 48 hours and what was the reading at that time? If a non-metal option is a consideration, then I would recommend if multiple patch tests are positive. Neuro Endocrinol Lett. 59, no. WebMELISA reactivity is directly dependent on lymphocyte concentration: the higher the lymphocyte concentration per test, the stronger the reactivity. True positive responses tend to persist for 7-10 days, false positives do not. Source
This a blood test that measures the immune response to titanium and is much more accurate than a traditional skin patch allergy test. Lindemann M, Rietschel F, Zabel M, Grosse-Wilde H.
