Modified Body Mass Index at Diagnosis is a Useful Predictor of Mortality in Patients With Antineutrophil Cytoplasmic Antibody-associated Vasculitis.

ABSTRACT:

Objective

We investigated whether modified body mass index (mBMI) at diagnosis could predict all-cause mortality during follow-up in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV).

Methods

The medical records of 203 AAV patients with BMI ≥18.5 kg/m² were reviewed. mBMI was calculated using an equation mBMI=BMI (kg/m²)×serum albumin (g/L). All-cause mortality was considered as a poor outcome, and the follow-up duration based on all-cause mortality was defined as the period from AAV diagnosis to death for deceased patients, and the period from AAV diagnosis to the last visit for surviving patients.

Results

The median age was 59.0 years (35.5% were male). The median BMI and mBMI were 22.8 kg/m² and 81
