Table 2.
Presence of non-dipping BP in pSLE despite otherwise normal ABPM
| Adequate ABPM studies, N = 18 | Non-dipping BP, N = 9 | |
|---|---|---|
| Normal, n (%) | 10 (55%) | 5 (56%) |
| White coat hypertension | 6 (33%) | 3 (33%) |
| Masked hypertension | 1 (6%) | 0 (0%) |
| Unclassified* | 1 (6%) | 1 (11%) |
Blood pressure categories based on updated definitions from the 2017 AAP guidelines
Nocturnal hypertension: SBP/DBP load ≥ 50% by ABPM
White coat hypertension: Casual BP ≥ 95th percentile but normal ABPM (mean 24-h SBP/DBP < 95th percentile and SBP/DBP load < 25%)
Masked hypertension: normal clinic BP but mean 24-h SBP/DBP > 95th percentile and SBP/DBP load ≥ 25% by ABPM
*Unclassified: elevated clinic BP (> 90th but < 95th percentile) with normal ABPM
