Blood pressure changes during alemtuzumab infusion for multiple sclerosis patients
Bibliographic record
Abstract
BACKGROUND AND PURPOSE: Blood pressure (BP) changes during alemtuzumab infusions are poorly understood. The aim of this study was to examine BP changes during alemtuzumab infusions in persons with multiple sclerosis (PwMS). METHODS: This was a retrospective cohort review of systolic (S) and diastolic (D) BP in PwMS receiving alemtuzumab. RESULTS: Thirty-one patients were identified; 22 (64.5%) were women. Mean age and disease duration were 35.2 ± 7.1 and 9.2 ± 5.4 years, respectively. There was no history of hypertension or vascular events. Mean baseline SBP was 119.8 ± 15.1 mmHg, 118.8 ± 14.3 mmHg and 106.5 ± 6.1 mmHg whilst mean DBP was 75.3 ± 9.2 mmHg, 74.1 ± 12.4 mmHg and 69.2 ± 4.3 mmHg at doses 1, 6 and 9, respectively. During the first cycle, SBP increased by 19.2 ± 9.4 mmHg, with comparable percentage increases over the five infusions (16%, 22%, 17%, 11%, 13%, respectively). DBP increased by 6.2 ± 3.8 mmHg with similar percentage increases over the five infusions (8.4%, 11.5%, 5.5%, 7%, 3%). For the second cycle, SBP increased by 16.9 ± 3.2 mmHg, with similar increases over the 3 days (12%, 15%, 17%). DBP increased by 5.4 ± 4.2 mmHg (11%, 9%, 12.8%). The third cycle demonstrated increased mean and percentage of SBP and DBP by 8.9 ± 2.3 mmHg (10%, 70%, 11.8%) and 4.2 ± 1.9 mmHg (3%, 2%, 6.5%), respectively. Collectively, for 31 patients, in the first cycle, mean SBP increased from 119.8 ± 15.1 mmHg to 138.8 ± 13 mmHg (p ˂ 0.001), whilst mean DBP increased from 74.5 ± 9.2 mmHg to 79.2 ± 9.1 mmHg (p = 0.007). Overall, 17 (54.8%) patients had increasing BP by ≥20% and nine (29%) had increasing BP by ≥20 mmHg from baseline. CONCLUSIONS: This demonstrates significant increases in BP during alemtuzumab infusions in PwMS.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
