ABSTRACT
Background: Pediatric Infammatory Multisystemic Syndrome associated to SARS-CoV2 (PIMS) happens 4 to 6 weeks after SARS-CoV2 infection1-2. Its early diagnostic recognition as well as its early management is important to avoid cardiac complications related to this pathology. Objectives: To highlight a frequent symptom in PIMS and improve its therapeutic care. Methods: The JIR Cohort database, an international registry collecting data on patients with pediatric infammatory diseases, was consulted to include patients between 03/15/20 and 12/31/2021. Results: Of the 140 patients in whom a diagnosis of PIMS was retained, we present a series of 38 patients (27%) who presented at diagnosis or during evolution, febrile torticollis or painful cervical involvement. These patients were on average 8.2 years old (0.6-15.2). The proportion of boys was 14 out of 38 (37%). Twenty-four patients out of 33 (73%) were hospitalized in intensive care. Ten patients out of 38 (26%) underwent cervical imaging, 5 (50%) had abnormalities such as collection or infltration of the soft tissues. At the therapeutic level, 27/38 patients (71%) received corticosteroid therapy, 33/38 (87%) immunoglobulins, and 26/38 (68%) antibiotic therapy. Conclusion: PIMS is a pathology with signifcant clinical heterogeneity and severe consequences in case of delay in therapeutic management. In this epidemic context, it is important to consider PIMS in any patient with febrile torticollis, especially if he does not respond to antibiotics.
