Which Factors Influence Decisions to Withdraw from Eculizumab: A Qualitative Study of Patients Diagnosed with aHUS.
Article in The patient, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAtypical haemolytic uremic syndrome (aHUS) is a rare life-threatening disease. Lifelong treatment with intravenous eculizumab every 2/3 weeks was recommended, but evidence is emerging that many patients can stop complement inhibition and restart should they relapse. However, little is known about the opinions and needs of patients with aHUS on withdrawal.
objectiveWe aimed to understand the factors that affect decisions to withdraw from treatment.
methodsThis was a qualitative study embedded in an eculizumab withdrawal trial. Data were collected through in-depth telephone interviews from January 2019 to June 2022. We conducted a thematic analysis using a constant comparative method. Interviewees included eight adults and the parents of 12 children with aHUS approached to participate in the trial. Follow-up interviews were conducted between January 2021 and June 2024 with those who withdrew from eculizumab.
resultsThe onset of aHUS had been traumatic for most. Regarding eculizumab, withdrawal group participants talked of the disruptive treatment regimen and side effects, the time off work/school, and impacts on taking holidays. Decisions to withdraw from eculizumab were driven by the wish to lead more normal lives and concerns about long-term treatment. Drivers for declining withdrawal focused on relapse and its perceived impact. After 2 years, the withdrawal group had regained a semblance of normality, though fears about relapse remained, and they were aware of the need for long-term follow-up. Participants had a greater sense of control over the necessary steps should they/their child relapse.
conclusionAn understanding of patient/parent experiences should guide discussions about eculizumab withdrawal. Although the availability of an alternative complement inhibitor reduces the frequency of infusions, most of the factors influencing withdrawal decisions remain unchanged. Support to alleviate fears in the early stages of withdrawal would be beneficial. Evidence from the main trial on successful withdrawal, and recovery time where eculizumab was reinstated, may provide reassurance to those who are uncertain about withdrawal.
