Transient injection site reaction to alirocumab during immune system activation: a case series.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Injection site reactions (ISRs) are known side effects of the proprotein convertase subtilisin kexin 9 (PCSK9) inhibitor alirocumab. Transient ISR to alirocumab after a long phase of good tolerability have not been reported previously. Case summary: A 55-year-old woman (Patient 1) and a 77-year-old man (Patient 2) were treated with alirocumab for the management of dyslipidaemia. Both patients tolerated the treatment without side effects for 7 and 2 months, respectively. After an upper respiratory tract infection in Patient 1 and a first COVID-19 vaccination in Patient 2, both patients suddenly developed ISR with erythema, calor, and itching upon 2 (Patient 1) and 1 (Patient 2) subsequent injection(s), respectively. Symptoms resolved with local steroids, oral antihistamines, and cooling. After termination of the presumed immune system activated state, alirocumab was well tolerated again in both patients without recurrence of any ISR upon repeated applications. Discussion: These are the first cases to report transient ISR to a PCSK9 inhibitor, possibly triggered by activation of the immune system, after prolonged good tolerability. Based on the transient and benign nature of the reaction, such patients should be encouraged to continue supervised treatment, as tolerability may return after resolution of the pro-inflammatory state.
