Relationship between ethnicity and multidisciplinary intervention for young people with rheumatic and musculoskeletal diseases.

Introduction: There is growing recognition of the impact of societal factors on health throughout a patient's lifespan. The COVID-19 pandemic has exposed the impact of racial disparity on health outcomes. Aims: We aimed to investigate the association between ethnicity and the multidisciplinary team (MDT) interventions for young people (YP) with complex care needs. Method: This retrospective, single-centre, cross-sectional study was conducted within the department of adolescent and young adult rheumatology at University College Hospital, London, between August 2019 and August 2021. We extracted demographic, clinical and laboratory data. The index of multiple deprivation was extracted from the Office for National Statistics database. R software was used for analysis. Results: We identified 310 YP referred to the MDT with a median age of 18 years (interquartile range 17-19). The female patient to male patient ratio was 2.4. Over a third of our cohort were from deprived areas. Comparison between Black, Asian and minority ethnic (BAME) and White ethnic groups revealed significant differences in terms of referral for pain optimisation (p=0.006), social support (p<0.00001), and adherence and non-clinic attendance (p=0.0004). Conclusion: Our findings reveal the importance of quality data for early identification and support of vulnerable YP, particularly those from BAME communities.

COVID-19 perniosis, a differential diagnosis to consider in adolescent patients presenting with chilblain-like lesions

Background/Aims Chilblain-like lesions (perniosis) have been reported frequently during COVID-19 pandemic in children and adolescents with no history of exposure to cold temperatures or underlying autoimmune conditions. Patients with these skin changes reported mild COVID-19 symptoms or previous contact with confirmed COVID-19 cases before they became symptomatic. In the majority of cases, a causal relationship between SARS-CoV-2 infection and chilblain-like lesion has not been proven. Methods Retrospective review of patients with chilblain-like lesions, possibly secondary to SARS-CoV-2 infection, presenting to a tertiary Adolescent Rheumatology service between January and August 2021. Results We identified five, male, adolescent patients (mean age, 16 years old) who presented with new onset of chilblain-like lesions affecting fingers, toes and heels in December 2020, which coincided with the peak of second wave of COVID-19 infection. One month prior to skin changes occurrence, 3 out of 5 patients experienced mild respiratory COVID-19-like symptoms and the rest of the patients were asymptomatic but were in contact with COVID-19 positive cases following outbreaks in schools. 1 of 3 symptomatic patients had a positive COVID-19 PCR test prior to skin manifestations. 2 out of 4 patients with heel lesions had deep, full thickness skin loss heel ulcers and 2 of 5 patients had superficially ulcerated lesions on a finger and toes, respectively, resulting in inability to attend school. None of the patients had any other symptoms or signs to suggest an underlying autoimmune connective tissue disorder. Demographics, clinical features and serological data are summarised in Table 1. One patient underwent a biopsy of heel ulcer which was histologically consistent with perniosis. In two patients (40%) chilblain like lesions resolved spontaneously within 2 months. Three patients (60%), with progressive ulcerated lesions, required various combinations of treatments with aspirin, calcium channel blockers (nifedipine), topical or oral steroids and hydroxychloroquine with complete resolution of symptoms within 6 months. Conclusion Chilblain-like lesions, including heel involvement associated with mildly symptomatic COVID-19 infection, have been reported before. Our mini-case series raises awareness of ulcerating chilblain like lesions possibly secondary to COVID-19 in adolescent patients, which require early recognition and instigation of treatment leading to better patient’s outcomes.
