Interventions Related to Takayasu Arteritis, their Clinical and Angiographic Associations, and Prognostic Relevance - A Cohort Study.

Objectives: We analysed interventions related to TAK, their pre-treatment clinical and angiographic associations, and prognostic relevance from a large ambispective, monocentric cohort of TAK from India.

Methods: Information regarding endovascular or open surgical interventions (aortoplasty, nephrectomy for refractory hypertension) was retrieved from a cohort of patients with TAK. Demographic characteristics, clinical features, and angiographic involvement were compared between patients with TAK who had undergone interventions with the rest of the cohort using multivariable-adjusted odds ratios (OR, with 95% CI).

Serum p-Glycoprotein and Monomeric C-Reactive Protein are Elevated in Takayasu Arteritis.

Purpose: Existing biomarkers including C-reactive protein (CRP) do not adequately distinguish active and inactive TAK. We compared serum p-glycoprotein (p-gp)/Multidrug Resistance Protein 1 (MDR1), monomeric CRP (mCRP), CRP, and mCRP:CRP ratio in Takayasu arteritis (TAK) and healthy controls and their relationship with disease activity.

Patients And Methods: Serum p-gp mCRP (ELISA) and CRP (nephelometry) were compared between consecutive adults with TAK (>18 years) enrolled from a prospective cohort (n = 92) and healthy controls (n = 29), and between active vs inactive TAK (n = 46 each).
