azathioprine has been researched along with ANCA-Associated Vasculitides in 91 studies

Azathioprine: An immunosuppressive agent used in combination with cyclophosphamide and hydroxychloroquine in the treatment of rheumatoid arthritis. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), this substance has been listed as a known carcinogen. (Merck Index, 11th ed)
azathioprine : A thiopurine that is 6-mercaptopurine in which the mercapto hydrogen is replaced by a 1-methyl-4-nitroimidazol-5-yl group. It is a prodrug for mercaptopurine and is used as an immunosuppressant, prescribed for the treatment of inflammatory conditions and after organ transplantation and also for treatment of Crohn's didease and MS.

Health-related Quality of Life as Assessed by the Short Form Health Survey (SF-36) Scores

The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 is a measure of health status and is commonly used in health economics as a variable in the quality-adjusted life year calculation to determine the cost-effectiveness of a health treatment. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. (NCT02749292)
Timeframe: Assessed throughout the study period, every 6 months unless such time point was not reached or was missed by the patient. Median follow-up period is of 4.1 years (IQR, 2.5 - 5.0)

Relapses recording period was from 6/1/2016 to 12/31/2021. The outcome was reported as the number of participants with disease relapse who had either positive ANCA titers specific for myeloperoxidase (MPO-ANCA) or proteinase 3 (PR3-ANCA). The Birmingham Vasculitis Activity Score for Wegener's Granulomatosis (BVAS/WG ) is a form with 34 predefined items grouped into 9 organ systems. The items are clinical features observed in patients with active ANCA vasculitis. Each item has a specified weight of either 3 or 1, depending on whether it reflects major or minor disease activity. The total BVAS/WG score is the weighted sum of individual manifestations that are present and believed to be due to active ANCA vasculitis. Higher scores reflect more active disease.

Organ Damage as Assessed by the Vasculitis Damage Index (VDI).

The Vasculitis Damage Index (VDI) is a validated formal assessment tool in ANCA-associated vasculitis clinical trials. The VDI distinguishes vasculitis-induced chronic damage from active inflammation or persistent disease. Each item represents a disease manifestation and is given a score (of 1) if present for at least 3 months. Neither the cause of damage (vasculitis vs treatment) nor an ongoing activity are taken into consideration. The VDI includes 64 items categorized into 11 groups (by organ system) and the scored items are summed to give a total score ranging from 0 to 64. A higher score means more accrued damage.

Combined Damage Assessment Score (Disease Related Damage Assessment)

Cumulative accrual of damage as measured by the combined damage assessment score (CDA). Each persistent or new occurrence of damage is given a score of 1. The cumulative accrual of damage is obtained by summing across the different types of damage to get an overall score (max score = 64). (NCT01697267)
Timeframe: data in Rows represent the change from randomization (month 4) to months 12, 24, 36, and 48.

Cumulative GC Exposure

Cumulative glucocorticoid (GC) exposure during the trial. The trial had a common close out date when the final patient reached month 36 in the trial. Patients were followed until month 48 or the common close out date, whichever happened sooner. Therefore, follow up varied between 36 and 48 months. Cumulative glucocorticoid exposure is presented as a dose in mg for during the treatment period (up to month 24) and across the whole trial (until month 48 or common close out when the final patient reached month 36).
