ABSTRACT

Introduction: La pandémie à SARS-CoV-2 a soulevé de nombreuses questions sur la prise en charge des maladies chroniques et leurs traitements. Les données concernant l'utilisation des biothérapies chez les adultes atteints de psoriasis sont rassurantes, mais manquent chez l'enfant. Par ailleurs, l'infection à SARS-CoV-2 pourrait influencer l'évolution du psoriasis chez l'enfant. L'objectif de cette étude était d'évaluer l'impact de l'infection à SARS-CoV-2 sur le psoriasis, et la sévérité de l'infection selon le traitement systémique reçu. Matériel et méthodes: Les données ont été collectées de février 2021 à février 2022 en provenance de 14 pays. Les enfants étaient inclus s'ils avaient moins de 18 ans, un antécédent de psoriasis ou apparu dans le moins suivant l'infection COVID-19, et avaient été infectés par le SARS-CoV-2 avec ou sans symptômes. Résultats: Au total, 117 enfants ont été inclus (filles : 49,6 %, âge moyen : 12,4 ans) avec 120 infections) SARS-CoV-2. La principale forme de psoriasis était le psoriasis en plaques (69,4 %) ;le psoriasis était actif avant l'infection dans 70,1 % des cas. La majorité des enfants ne prenaient pas de traitement systémique au moment de l'infection (54,2 %), 33 enfants (28,3 %) étaient sous biothérapie (principalement anti-TNF alpha et ustékinumab), et 24 (20,0 %) sous traitement systémique conventionnel (principalement méthotrexate). L'infection était confirmée chez 106 enfants (88,3 %) et 3 ont eu la maladie 2 fois (1 enfant asymptomatique sous ustékinumab et 2 enfants symptomatiques sans traitement systémique). L'infection était symptomatique chez 75 enfants (62,5 %) avec une durée moyenne des symptômes de 6,5 jours, significativement plus longue chez les enfants sous traitement systémique conventionnel (p = 0,002) ou sans traitement systémique (p = 0,006) par rapport aux enfants traités par biothérapies. Six enfants ont nécessité une hospitalisation, dont un enfant en réanimation ;ils étaient plus fréquemment sous traitements systémiques conventionnels par rapport aux autres enfants (p = 0,01), et principalement sous méthotrexate (p = 0,03). Aucun enfant sous biothérapie n'a été hospitalisé, et aucun décès n'a été rapporté.Après l'infection, le psoriasis s'est aggravé dans 17 cas (15,2 %), sans modification du phénotype sauf pour un enfant avec un psoriasis initialement en plaques qui a eu suite à l'infection une poussée de psoriasis en gouttes. Neuf enfants (8,0 %) ont développé un psoriasis de novo dans le mois qui a suivi l'infection, plus souvent un psoriasis en gouttes (p = 0,01) par rapport aux enfants ayant un antécédent connu de psoriasis. Ces enfants avaient un antécédent familial de psoriasis dans 75,0 % des cas. Discussion: L'utilisation des biothérapies semble rassurante sans augmentation du risque de forme sévère de COVID-19 chez les enfants atteints de psoriasis. L'infection à SARS-CoV-2 était responsable du développement de psoriasis de novo ou de l'aggravation d'un psoriasis connu chez certains enfants.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has raised questions regarding the management of chronic skin diseases, especially in patients on systemic treatments. Data concerning the use of biologics in adults with psoriasis are reassuring, but data specific to children are missing. Moreover, COVID-19 could impact the course of psoriasis in children. OBJECTIVES: The aim of this study was therefore to assess the impact of COVID-19 on the psoriasis of children, and the severity of the infection in relation to systemic treatments. METHODS: We set up an international registry of paediatric psoriasis patients. Children were included if they were under 18 years of age, had a history of psoriasis, or developed it within 1 month of COVID-19 and had COVID-19 with or without symptoms. RESULTS: One hundred and twenty episodes of COVID-19 in 117 children (mean age: 12.4 years) were reported. The main clinical form of psoriasis was plaque type (69.4%). Most children were without systemic treatment (54.2%); 33 (28.3%) were on biologic therapies, and 24 (20%) on non-biologic systemic drugs. COVID-19 was confirmed in 106 children (88.3%) and 3 children had two COVID-19 infections each. COVID-19 was symptomatic for 75 children (62.5%) with a mean duration of 6.5 days, significantly longer for children on non-biologic systemic treatments (P = 0.02) and without systemic treatment (P = 0.006) when compared with children on biologics. The six children who required hospitalization were more frequently under non-biologic systemic treatment when compared with the other children (P = 0.01), and particularly under methotrexate (P = 0.03). After COVID-19, the psoriasis worsened in 17 cases (15.2%). Nine children (8%) developed a psoriasis in the month following COVID-19, mainly a guttate form (P = 0.01). DISCUSSION: Biologics appear to be safe with no increased risk of severe form of COVID-19 in children with psoriasis. COVID-19 was responsible for the development of psoriasis or the worsening of a known psoriasis for some children.

ABSTRACT

BACKGROUND: A marked increase in frequency of acute acral eruptions (AAE) was observed in children during the COVID-19 pandemic in the spring period. OBJECTIVES: In this observational multicenter study, based on children with AAE, we aimed to assess the proportion of household members possibly infected by SARS-CoV-2. METHODS: We collected data from all children observed with AAE, prospectively from April 7, 2020 to June 22, 2020, and retrospectively since February 28, 2020. The primary outcome was the household infection rate, defined as the proportion of family clusters having at least one member with COVID-19 infection other than the child with AAE ("index child"). The definition of a case was based on characteristic clinical signs and a positive PCR or serology. RESULTS: The study included 103 children in 10 French departments and in Quebec. The median age was 13 years and the interquartile range [8-15], with a female-to-male ratio of 1/1.15. In children with AAE, all PCR tests were negative (n=18), and serology was positive in 2/14 (14.3%) cases. We found no significant anomalies in the lab results. A total of 66 of the 103 families (64.1%) of included children had at least one other infected member apart from the index child. The total number of household members was 292, of whom 119 (40.8%) were considered possibly infected by SARS-CoV-2. No index children or households exhibited severe COVID-19. DISCUSSION: Among the 103 households included, 64.1% had at least one infected member. Neither children with AAE nor their households showed severe COVID-19.
