[55, 22, 8, 24, 144] The major justification for the use of corticosteroids is the impending danger of blindness in untreated patients.Patients who present with visual symptoms have a 22-fold increased chance of visual improvement if therapy is started within the first day. et al. [18] These infiltrates erode the middle and inner layers of the arterial tunica media leading to conditions such as aneurysm and dissection. Both polymyalgia rheumatica and temporal arteritis tend to run a self-limited course of several months to as long as five years. 4. Stiffness is greatest in the morning and lasts 30 to 60 minutes after patients arise. [4] However, in about 10% of people the temporal artery is normal. Giant cell arteritis and polymyalgia rheumatica. N Engl J Med. Calabrese LH, Giant cell arteritis. [2] It is more common in women than in men, by a ratio of 2:1,[4] and more common in those of Northern European descent, as well as in those residing further from the Equator. 2013;62(6 suppl):S5-S9. et al. If the biopsy findings are negative but temporal arteritis is still strongly suspected, biopsy of the opposite side is indicated. Arend WP, Otherwise, the arteries could be permanently damaged. Adapted with permission from Hunder GG, Bloch DA, Michel BA, Stevens MB, Arend WP, Calabrese LH, et al. On physical examination, the patient appeared distressed, but she was afebrile and had normal blood pressure and pulse. Andersson R, Introduction. 1983;42:702–3. Bird HA, A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Diagnostic dilemmas in polymyalgia rheumatica. [14] Early and accurate diagnosis is important to prevent ischemic vision loss. Temporal arteritis is the most common form of giant cell arteritis, a condition in which some arteries become tender and swollen. Patients are instructed to see their physician immediately if symptoms recur or they develop new headache, jaw claudication or visual problems. It is a medical emergency as it may lead to ischemic complications, including permanent visual loss in 20 % of untreated patients. Immediate, unlimited access to all AFP content. She had no tenderness, pain or obvious swelling over her temporal arteries. Throughout treatment, clinical condition is assessed periodically. Suspicion is strengthened by the clinical findings of an elevated ESR, scalp tenderness, normocytic anemia or superficial artery abnormality. Giant cell arteritis often causes headache and sometimes acute vision loss. 1997;337:1336–42. An evaluation of criteria for polymyalgia rheumatica. Philadelphia: Saunders, 1993:103–12, Adapted with permission from Swannell AJ. They may also find it difficult to put on their clothes, groom their hair and brush their teeth. 1979;38:434–9. This diagnostic scheme has a sensitivity of 93 percent and a specificity of 91 percent.16, Patient age older than 50 years at disease onset, Development of symptoms or findings beginning when a patient is older than 50 years, New onset or new type of localized pain in the head, Temporal artery tenderness on palpation or decreased temporal artery pulse, unrelated to arteriosclerosis of the cervical arteries, ESR greater than 50 mm per hour by the Westergren method, Biopsy specimen with artery showing vasculitis characterized by a predominance of mononuclear cell infiltration or granulomatous inflammation, usually with multinucleated giant cells. [18], The pathological mechanism is the result of an inflammatory cascade that is triggered by an as of yet determined cause resulting in dendritic cells in the vessel wall recruiting T cells and macrophages to form granulomatous infiltrates. In: Kelley WN, et al. US, ultrasound. 12. [4], Treatment is typically with high doses of steroids such as prednisone or prednisolone. Irreversible blindness is the most common serious consequence. Corticosteroid therapy provides rapid and dramatic improvement of the clinical features of both conditions. The most common is fever.8 Some patients have a temperature of 39°C (102.2°F), as well as night sweats. Choose a single article, issue, or full-access subscription. Pountain G, [4] Females are more often affected than males. It is important that you get treatment right away. [27] Short-term side effects of prednisone are uncommon but can include mood changes, avascular necrosis, and an increased risk of infection. 1994;344:543–4. GCA is the most common form of systemic vasculitis in adults. Gromnica-Ihle EJ. However, other large vessels such as the aorta can be involved. Bloch DA, Here we review the current evidence for each diagnostic modality and propose an algorithm to diagnose cranial-GCA in a setting with rapid access to high quality US. [4] The first description of the condition occurred in 1890.[1]. Although dosage recommendations vary, most investigators recommend the use of prednisone administered orally in a dosage of 40 to 60 mg per day. Jones JG, [4][8] Diagnosis is suspected based on symptoms, blood tests, and medical imaging, and confirmed by biopsy of the temporal artery. Giant cell arteritis causes headaches, scalp tenderness, jaw pain, vision problems, and potentially blindness. McGee SR. Mason JC, A segmental involvement pattern is typica… [24] The dose of corticosteroids is generally slowly tapered over 12–18 months. GCA and PMR are so closely linked that they are often considered to be different manifestations of the same disease process. The starting dosage of prednisone ranges from 5 to 20 mg per day. Giant cell arteritis is a chronic inflammatory disease characterized by the progressive inflammation of many arteries of the body (panarteritis). He is currently completing a fellowship in faculty development at the University of North Carolina at Chapel Hill School of Medicine. Steroids do not prevent the diagnosis from later being confirmed by biopsy, although certain changes in the histology may be observed towards the end of the first week of treatment and are more difficult to identify after a couple of months. A trial of nonsteroidal anti-inflammatory drugs may be attempted in patients with polymyalgia rheumatica. [33] Tocilizumab has been found to be effective at minimizing both recurrence, and flares of GCA when used both on its own and with corticosteroids. [21] However, a negative result does not definitively rule out the diagnosis; since the blood vessels are involved in a patchy pattern, there may be unaffected areas on the vessel and the biopsy might have been taken from these parts. Hunder GG. Polymyalgia rheumatica and temporal arteritis are closely related inflammatory conditions that affect different cellular targets in genetically predisposed persons. Arch Intern Med 1997;157:163, Adapted with permission from Hunder GG, Bloch DA, Michel BA, Stevens MB, Arend WP, Calabrese LH, et al. Bird HA, It has not been formally tested in a randomized clinical trial. [35] Giant-cell arteritis is also known as "cranial arteritis" and "Horton's disease". Attempts to abduct either arm above 90 degrees produced marked pain. Three or more of the following, or at least one of the following plus positive results on temporal artery biopsy: Less than two weeks from onset of symptoms to maximal symptoms, Morning stiffness lasting longer than one hour, Shoulder and pelvic girdle muscle pain without weakness, Symptom duration of more than two months unless treated, ESR greater than 30 mm per hour or C-reactive protein level greater than 6 mg per L, No rheumatoid arthritis, inflammatory arthritis or malignant neoplasm, Prompt and dramatic response to systemic corticosteroid therapy. Chronic inflammation is sometimes confined to the different branches of the heart's main artery (aorta) and any large arteries can become inflamed. She said that her older brother had been treated with “steroids” for a similar affliction five years earlier. Hunder GG. Guest editor of the series is Ted D. Epperly, COL, MC, USA. Immunopathogenesis, diagnosis, and treatment of giant cell arteritis, temporal arteritis, polymyalgia rheumatica, and Takayasu's arteritis. Hunder GG, [14], While studies vary as to the exact relapse rate of giant cell arteritis, relapse of this condition can occur. American College of Rheumatology Task Force on Osteoporosis Guidelines. The American College of Rheumatology 1990 criteria for the classification of giant cell arteritis. Andersson R, In most patients with temporal arteritis, clinical symptoms resolve and the ESR returns to normal within two to four weeks. [15], The varicella-zoster virus (VZV) antigen was found in 74% of temporal artery biopsies that were GCA-positive, suggesting that the VZV infection may trigger the inflammatory cascade. Stevens MB, [23], GCA is considered a medical emergency due to the potential of irreversible vision loss. Early diagnosis enabling a rapid initiation of treatment is of critical importance. Polymyalgia: easy to overlook. 7. Polymyalgia rheumatica and giant cell arteritis. Relapses are most likely to occur in the first 18 months of therapy or within 12 months after the cessation of corticosteroid treatment. Temporal arteritis, or giant cell arteritis, involves humoral and cellular immune responses that are limited to vessels with an internal elastic component.1 Compared with polymyalgia rheumatica, temporal arteritis is the more serious condition. et al. Contact Textbook of rheumatology. The use of arterial biopsy in patients with symptoms of polymyalgia rheumatica alone is currently under debate. Dixon AS, Although the Creactive protein level is typically elevated in patients with these conditions, it provides no better data than the simpler and less expensive ESR. Therefore, the present study aim at validating a diagnostic algorithm of giant cell arteritis using color Doppler imaging of temporal arteries and cervicocephalic axes as first screening method. Because polymyalgia rheumatica and temporal arteritis probably represent different manifestations of the same disease process, symptoms of the conditions often overlap. Walker SE. BMJ. Swannell AJ. The initial manifestations and clinical findings in 100 consecutive patients are shown in Table 1.9 Headache is the most frequent symptom and also the most common initial symptom. The ESR is the most useful serum laboratory test for diagnosing polymyalgia rheumatica and temporal arteritis. Miller D, Lancet. [4] Once symptoms have resolved the dose is then decreased by about 15% per month. Another frequent complaint in temporal arteritis is jaw claudication resulting from inflammation of the maxillary artery. Arch Intern Med 1997;157:163. Giant cell arteritis. Giant cell arteritis (GCA) is the most frequent type of vasculitis, occurring in people older than 50 years. Chewing may produce pain bilaterally or predominantly on the affected side. [18] This pathway is suppressed with glucocorticoids,[19] and more recently it has been found that IL-6 inhibitors also play a suppressive role. An evaluation of criteria for polymyalgia rheumatica. These arteries narrow, so not enough blood can pass through. [20] It affects about 1 in 15,000 people over the age of 50 per year. METHODS: Retrospective review of 213 consecutive cases of temporal artery biopsy (TAB) seen at a single academic center over a 10-year period (2000-2009). Ocular symptoms are initially unilateral, with the second eye becoming affected in one to 10 days. 1992;305:68–9. It is categorized as a large-vessel vasculitis (Chapel Hill 2012). Background/Purpose: Giant Cell Arteritis (GCA) is the most common systemic vasculitis in patient over 50 years of age. Nordborg E, Compared with temporal arteritis, polymyalgia rheumatica is much more common, affecting one in 200 persons older than 50 years. Diagnostic dilemmas in polymyalgia rheumatica. [4] GCA is frequently associated with polymyalgia rheumatica. Diagnostic dilemmas in polymyalgia rheumatica. Gromnica-Ihle EJ. PMR usually lacks the cranial symptoms, including headache, pain in the jaw while chewing, and vision symptoms, that are present in GCA. It can be argued that these patients can be safely managed with close observation for development of signs of temporal arteritis. 15. Brooks RC, Bensen WG, Arterial biopsy usually confirms the diagnosis of temporal arteritis. The prevalence of polymyalgia rheumatica was estimated at 701, and the prevalence of giant cell arteritis was estimated at 204 for every 100,000 people 50 years of age and older, in a study of 2015 data. Blood cultures may provide evidence of occult endocarditis in the patient with unexplained fever. 5. Adapted with permission from Swannell AJ. Laboratory tests revealed elevation of the ESR to 105 mm per hour and the presence of a normochromic, normocytic anemia. A decrease in the temporal artery pulse is frequently noted. A primary care physician's guide to polymyalgia rheumatica. ... Clinical presentations of giant cell arteritis (GCA) are protean, and it is vital to make a secure diagnosis and exclude mimics for urgent referrals with suspected GCA. After symptoms resolve, the corticosteroid is tapered by 2.5 mg every two to four weeks until a dosage of 10 mg per day is reached. Involvement of the lingual artery can result in pain and blanching of the tongue. [4] This mainly affects arteries around the head and neck, though some in the chest may also be affected. Autoimmune responses are believed to play a prominent role in polymyalgia rheumatica, with bursitis, synovitis and tenosynovitis of the proximal shoulder and hip girdles being characteristic features.3. Hanley D, 1997;337:382–7. Reprints are not available from the authors, The opinions and assertions contained herein are the private views of the authors and are not to be construed as official or as reflecting the views of the Army Medical Department or the Army Service at large. The pain is typically centered over the temporal or occipital regions, but pain in other locations cannot be discounted. Dixon AS, Serum protein electrophoresis can be used to assess the probability of myeloma. Rheum Dis Clin North Am. [22] A Characterised as intimal hyperplasia and medial granulomatous inflammation with elastic lamina fragmentation with a CD 4+ predominant T cell infiltrate, currently biopsy is only considered confirmatory for the clinical diagnosis, or one of the diagnostic criteria. Granular material and abnormally large cells (giant cells) accumulate in the elastic lining of the arteries. Textbook of rheumatology. Symptoms may include headache, pain over the temples, flu-like symptoms, double vision, and difficulty opening the mouth. The precise relationship between temporal arteritis and polymyalgia rheumatica remains unknown. Hanley D, Polymyalgia rheumatica and giant cell arteritis. She said that her older brother had been treat… This review covers recent advances … Dr. Harrover received his medical degree from the Medical College of Georgia School of Medicine, Augusta. Jones JG, Kyle V. Screening should be done on a case-by-case basis based on the signs and symptoms of people with GCA. Reprints are not available from the authors. Measurement of the thyroid-stimulating hormone level can diagnose thyroid dysfunction. Sweeney K. Skingle SJ, [29][30] It is unclear whether adding a small amount of aspirin is beneficial or not as it has not been studied. Caselli RJ, The etiology of GCA is not well understood, but a combination of genetic and environmental factors is thought to play a role in its development.
