  Purpose

Giant Cell Arteritis (GCA) causes inflammation and narrowing of blood vessels and can cause blindness in one third of patients. It is important that a prompt, accurate diagnosis of GCA is made and treatment given as steroids for two or more years. Currently there is no 100% accurate test for GCA. Patients usually have new headache and scalp tenderness, typically with an abnormal blood test. However, it can be difficult to distinguish non-serious forms of headache from GCA; infection produces similar abnormal blood results. If there is a suspicion of GCA, treatment with steroids is started straight away. To confirm a diagnosis, the patient will need a biopsy of a temporal artery (a minor procedure performed under local anaesthetic to remove a sample of one of the scalp arteries). However, up to 44% of patients will have a normal biopsy. Therefore it is difficult to know if a patient with a normal biopsy does or does not have GCA. Withdrawing steroid treatment may increase the risk of blindness. Continuing treatment in a patient without GCA increases the risk of side effects (e.g., weight gain, infection risk, osteoporosis and fracture risk, high blood pressure, diabetes, cataracts). It is important to improve diagnostic tests for GCA. Another test to help in diagnosing GCA is an ultrasound scan of the arteries in the side of the head and under the arms. Ultrasound does not involve surgery; it is a simple test which can be performed as an out patient. Gel is applied to both sides of the head and under each arm. A sound probe is placed over the artery at each site to produce the scan.

The investigators' study will examine the role of ultrasound in diagnosis of 402 patients with suspected GCA. All patients will have an ultrasound examination in addition to biopsy within a week of starting steroids. Patients will be treated according to usual practice. After six months, the investigators will reassess the diagnosis. The investigators will look at the accuracy of ultrasound compared with or combined with biopsy. The investigators will look at how a doctor's knowledge of ultrasound results or biopsy results alone would affect the diagnosis and recommendation to continue or stop steroid treatment. The investigators will assess whether knowledge of both results together would alter the diagnosis and treatment. The investigators will collect information to estimate the costs of different ways of diagnosing GCA in relation to the impact on quality of life.

Primary Outcome Measures:
  • To evaluate the diagnostic accuracy (sensitivity and specificity) of ultrasound as an alternative to temporal artery biopsy for the diagnosis of GCA in patients referred for biopsy with suspected GCA. [ Time Frame: Six months ] [ Designated as safety issue: No ]
  • To evaluate the cost-effectiveness (incremental cost per QALY) of ultrasound instead of biopsy in the diagnosis of GCA. [ Time Frame: Six months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To evaluate inter-observer agreement in the assessment of ultrasound and temporal artery biopsy [ Time Frame: Six months ] [ Designated as safety issue: No ]
  • To elicit expert views on the appropriateness of performing a biopsy following ultrasound using clinical vignettes [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • To evaluate the diagnostic accuracy (sensitivity and specificity) of the sequential diagnostic strategy as an alternative to temporal artery biopsy alone in the diagnosis of GCA [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • To evaluate the cost-effectiveness (incremental cost per QALY) of the diagnostic strategy of combined ultrasound and biopsy instead of biopsy alone in the diagnosis of GCA. [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • Specific adverse events measured at each assessment; daily and cumulative steroid dose; steroid side effects; and pain or dysaesthesia at the biopsy site. [ Time Frame: Six months ] [ Designated as safety issue: Yes ]
  • Evolution of an alternative diagnosis [ Time Frame: Six months ] [ Designated as safety issue: No ]
  • Negative predictive value of ultrasound in preventing the need for temporal artery biopsies. [ Time Frame: Six months ] [ Designated as safety issue: No ]
  • Cost analysis of performing a screening ultrasound examination plus biopsy as part of the diagnostic workup of all patients with suspected GCA; or of performing a screening ultrasound examination instead of biopsy; or of performing a screening ultrasound [ Time Frame: Six months ] [ Designated as safety issue: No ]
  • Cost analysis of performing a screening ultrasound examination instead of biopsy in cases with a very low probability of GCA as part of the diagnostic workup of all patients with suspected GCA. [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • Prediction of potential harm done to patients by over diagnosis or under diagnosis of GCA as a result of ultrasound use, either alone or in combination with biopsy [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
  • Value of axillary artery ultrasound scanning in contributing to the diagnosis of GCA. [ Time Frame: Six months ] [ Designated as safety issue: No ]
  • Analysis of proportion of patients with a biopsy positive halo, stenosis, or occlusion assessed by high resolution ultrasound [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • Presence of characteristic features of GCA on temporal artery biopsy in relation to clinical and ultrasound findings [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]

Criteria

Inclusion Criteria: for the cohort study

  1. A clinical suspicion of new diagnosis of GCA e.g. patients with a new onset of headache, scalp tenderness, with or without elevated CRP or ESR, jaw or tongue claudication with or without visual loss.
  2. The clinician decides that the patient requires an urgent temporal artery biopsy to determine whether or not the diagnosis is GCA.
  3. The patient agrees and provides NHS consent to undergo a temporal artery biopsy as part of standard care.
  4. Patients have been started on high dose glucocorticoids or will be started on high dose glucocorticoids.
  5. Patients must be willing to attend for an ultrasound scan of their temporal and axillary arteries.
  6. Participants must be willing to give informed written consent or willing to give permission for a nominated friend or relative to provide written informed assent if they are unable to do so because of physical disabilities e.g. sudden onset of blindness/vision loss which can be caused by GCA (this will be made clear in the ethics approval application).
  7. Must be 18 years of age or over.

For the training cases

  1. Patients attending hospital outpatient or in patient departments for assessment for any condition (apart from giant cell arteritis or polymyalgia rheumatica) or healthy staff volunteers.
  2. Above the age of 50 years.
  3. Willing to attend for an ultrasound scan of their temporal and axillary arteries.
  4. Willing and able to give written informed consent.

Exclusion criteria: for the cohort study

  1. Previous diagnosis of GCA.
  2. Use of high dose glucocorticoid (>20mg prednisolone/day) for management of current suspected GCA for more than 7 days prior to the dates of the ultrasound and biopsy.
  3. Long term (>1 month) high dose (>20mg per day at any time) steroids for conditions other than PMR, within three months prior to study entry.
  4. Inability to give informed consent (either written consent or verbal assent from a relative or carer)
  5. Inability to undergo an ultrasound scans of the temporal and axillary arteries.
  6. Patients with a known cause of headache (not due to GCA), or any condition which would preclude the need for a temporal artery biopsy.
  7. Patients who are unable to undergo an ultrasound scan and a temporal artery biopsy within 7 days of starting glucocorticoids.

For the training cases

  1. Diagnosis of suspected GCA or a previous history of diagnosed or suspected GCA.
  2. Inability to give written informed consent.
  3. Inability to undergo an ultrasound scans of the temporal and axillary arteries
