Doctors' Answers to "Frequently Asked Questions" - Temporal Arteritis
Answer: I don't have much information about the medical history of this disease. It would be available in older textbooks in any medical school library. The disease is a systemic vasculitis affecting medium and occasionally larger arteries. There is only speculation about the etiology and seems to be auto-immune in nature. There is no history of earlier events that is known to cause the inflammation.
Answer: About the only interaction would be an increased risk of ulcers of the gi tract. Generally, most physicians would try some medications to prevent/minimize the risk of ulcers. Also, most physicians would use some medication while taking the prednisone to minimize the bone loss inherent in using steroids. Discuss this with him/her if you haven't.
Answer: Temporal Arteritis is a systemic inflammatory disease of the small and medium size arteries of the body. It is usually manifested by temporal pain, jaw claudication(pain on chewing) and a bunch of systemic complaints-aches, fatigue, joint pain etc. The diagnosis is made by biopsy and by an elevated sedimentation rate(lab test). About 10% of the time, biopsy will miss an affected area of the arteries and consequently we treat some patients with classic symptoms who are biopsy negative. Usually, we treat biopsy proven disease only. The only current treatment is steroids-medrol would be one of these. The dosage is given to drive the sedimentation rate back to normal and abolish the symptoms as well. Untreated disease can result in blindness, so we are very careful with this disease. We usually do not treat unproven disease since the long term sequelae of steroids can be quite marked.
Answer: I doubt the NPH theory; but, there is clear cerebritis seen in many inflammatory arteritis. Temporal arteritis clearly affects the mentation of some patients. I would correlate his sed rate over time with some measurable part of the mini mental status exam. However, if his sed rate is 80 he is not receiving adequate prednisone dosing. Checking an antinuclear cytoplasmic antibody( P-ANCA and C-ANCA) might be helpful. Also, this cerebral inflammation is more common in lupus than TA-has he had an ANA to test for lupus? CNS involvement is difficult to diagnose;but, fairly common(10% or so) of many of the vasculitis syndromes.
Answer: Temporal Arteritis is a inflammatory disease of small and medium arteries. Although the diagnosis is made by biopsy of the Temporal Artery it is thought to affect most arteries in the body. The cause is not known, but is peculiar in that it affects older patients predominantly. This disease is not seen before the age of 55 or so. Diagnosis is made by biopsy of the temporal artery. Sometimes two or more biopsies are necessary to find an area of inflammation due to the "skip" nature of the inflammatory lesions. Treatment is limited to use of steroids. This is to avoid the possible blindness which can result if not treated. Side effects are generally limited to the side effects of the steroids, but inadequate treatment with insufficient steroids can lead to blindness. Temporal arteritis can reoccur and will usually require treatment in excess of 3 months. Treatment is begun to decrease the sedimentation rate (a blood test) and the amount of steroid necessary is kept to a minimum due to the potential side effects of steroids.
Answer: Temporal Arteritis is a disease which afflicts patients over 50 or so. It is seen with inflammation of the temporal artery;but, probably affects most of the medium size arteries in the body. The only treatment is steroids(like prednisose) until the sedimentation rate(a lab test) returns to normal. The disease can cause blindness and strokes, so it is treated aggressively. Treatment usually is a minimum of three months with most patients taking 6-8 months of steroids. Relapses are fairly common. Ensure that her glucose is not elevated with the steroids. Older patients tend to develop diabetes due to steroid treatment much more than younger patients and this can cause some of the problems you describe.
