Concurrent Nemolizumab-Induced Cutaneous Adverse Events and Asthma Exacerbation in a Patient With Prurigo Nodularis With Resolution of Both Conditions After Switching to Dupilumab.

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
Prurigo nodularis (PN) is a chronic pruritic inflammatory disease driven by Th2-dominant immune dysregulation and neural hyperactivity. Conventional therapies often fail, while biologics such as dupilumab and nemolizumab have shown efficacy. However, nemolizumab can cause cutaneous adverse events (cAEs) and occasional asthma exacerbation. An 82-year-old woman with long-standing PN and well-controlled asthma developed cAEs and asthma exacerbation one month after initiating nemolizumab, an IL-31 receptor antagonist. Although nemolizumab markedly improved pruritus and PN lesions, acute eczematous eruptions and erythematous papules appeared on previously unaffected skin, accompanied by worsening asthma symptoms. After switching to dupilumab (IL-4/IL-13 inhibitor), both cAEs and asthma improved, with complete resolution within two months. The mechanism underlying nemolizumab-induced cAEs and asthma remains unclear, but activation of Th2-driven inflammation following IL-31 blockade has been proposed. To our knowledge, this is the first reported case of concurrent nemolizumab-induced cAEs and asthma exacerbation in a patient with PN, successfully managed with dupilumab. Given that asthma exacerbations have occurred only in patients with preexisting asthma, careful monitoring is warranted when administering nemolizumab. Further studies are needed to clarify its mechanism and management strategies.
