Introduction:
Takayasu’s arteritis (TA), a large vessel vasculitis has various initial presenting manifestations; making it difficult to diagnose. Hence, the number of those with the disease in the population is underestimated. The study intends to update local data and to describe different presentations of the disease to enhance awareness for TA.
Methods:
This is a retrospective study done in a tertiary government hospital. Twenty-two out of twenty three charts of patients diagnosed with TA based on the 1990 ACR criteria were reviewed. Demographic profile, initial clinical manifestations, imaging, treatment and outcomes were collected. Descriptive statistics was applied. Institutional Review Board approval was obtained prior to study initiation.
Results:
Majority (90.1%) were female; mean age at onset of symptoms and at diagnosis were 30.4 (+12.3)years and 33.2 (+12.0)years respectively. The common reasons for consult were hypertension (26.3%), claudication (21.1%) and abdominal pain (11%). Laboratories showed elevated erythrocyte sedimentation rate (87.5%), leukocytosis (43.8%), anemia (31%) and thrombocytosis (4.5%). Common imaging findings were cardiomegaly (27.3%), aortic regurgitation (27.3%) and carotid stenosis (18.2%). CT angiogram in 90% of cases demonstrated arterial wall narrowing. Other findings were aneurysm (31.8%), contour irregularities (13.6%) and femoral artery occlusion (4.5%). Treatment for active disease were glucocorticoids alone (44%) and combined glucocorticoids and other immunosuppressants (56%). Of the 22 records reviewed, six patients (27%) had stroke. Four (18.2 %) had different surgical procedures; ray amputation of toe for digital ischemia, embolectomy for digital gangrene, balloon angioplasty of the renal artery and renal angioplasty for stenosis. Two (9.1%) who had pregnancies after TA diagnosis had premature deliveries without neonatal complications. No mortality was recorded over the mean follow-up of 49.33 patient-years.
Conclusion
Clinicians should be aware of the different initial presenting signs and symptoms of TA since development of collateral circulation may mask other symptoms. Thus, thorough history and physical assessment are essential tools in the diagnosis of TA.
