RESUMO
Context: Successful rates of hematopoietic stem cell transplantation (HSCT) face paralleled escalation of late endocrine and metabolic effects. Objective: This work aimed to characterize these sequelae distinguishing between the underlying pathologies and treatments received. Methods: A retrospective descriptive study was conducted in 157 children post-HSCT (hematopoietic pathology [N = 106], solid tumors [N = 40], and rare entities [N = 11]) followed at a single endocrine department between 2009 and 2019. Regression analysis was used to ascertain association. Results: Of all patients, 58.7% presented with at least one endocrine abnormality. Endocrinopathies post HSCT were most frequently developed in lymphoblastic leukemia (60.5% of them), whereas myeloid leukemias had the fewest. A total of 64% of patients presented with primary hypogonadism, 52% short stature, and 20% obesity. Endocrinopathy was associated with older age at HSCT (9.78 years [6.25-12.25] vs 6.78 years [4.06-9.75]) (P < .005), pubertal Tanner stage V (P < .001), chronic graft-vs-host disease (GVHD) (P = .022), and direct gonadal therapy (P = .026). The incidence of endocrinopathies was higher in girls (15% more common; P < .02) and in patients who received radiotherapy (18% higher), steroids (17.4% increase), allogenic HSCT (7% higher), thymoglobulin, or cyclophosphamide. Those on busulfan presented with a 27.5% higher rate of primary hypogonadism (P = .003). Conclusion: More than half of children surviving HSCT will develop endocrinopathies. Strikingly, obesity has risen to the third most frequent endocrine disruption, mainly due to steroids, and partly adhering to the general population tendency. Lymphoblastic leukemia was the condition with a higher rate of endocrine abnormalities. Female sex, older age at HSCT, pubertal stage, allogenic transplant, radiotherapy, alkylating drugs, and GVHD pose risk factors for endocrine disturbances.
RESUMO
BACKGROUND: The COVID-19 pandemic has brought innumerable reports of chilblains. The relation between pernio-like acral eruptions and COVID-19 has not been fully elucidated because most reported cases have occurred in patients with negative microbiological tests for SARS-CoV-2. METHODS: A retrospective study of 49 cases of chilblains seen during the first year of the pandemic in a children's hospital in Madrid, Spain. The incidence of these skin lesions was correlated with the number of COVID-19 admissions and environmental temperatures. Patients were separated into two groups depending on the day of onset (strict lockdown period vs. outside the lockdown period). RESULTS: Most chilblains cases presented during the first and third waves of the pandemic, paralleling the number of COVID-19 admissions. The first wave coincided with a strict lockdown, and the third wave coincided with the lowest ambient seasonal temperatures of the year. Systemic symptoms preceding chilblains were more frequent in the first wave (45.8% vs. 8.0%, p = .002), as was the co-occurrence with erythema multiforme-like lesions (16.7% vs. 0%, p = .033). Laboratory test and skin biopsies were performed more frequently in the first wave (75.0% vs. 12.0%, p < .001; and 25.0% vs. 0%, p = .007; respectively). Five patients developed recurrent cutaneous symptoms. CONCLUSIONS: An increased incidence of chilblains coincided not only with the two major waves of the pandemic, but also with the strict lockdown period in the first wave and low seasonal temperatures during the third wave. Both increased sedentary behaviors and cold environmental temperatures may have played an additive role in the development of COVID-19-related chilblains.

During examination of cases of chilblains in children and adolescents, we identified four patients who also showed skin lesions similar to erythema multiforme (EM). They had no other known triggers for EM. One of them had a positive PCR for SARS-CoV-2, while the other three were negative. Skin biopsies from two patients showed features not typical of EM, such as deep perivascular and perieccrine infiltrate and absence of necrosis of keratinocytes. Immunohistochemistry for SARS-CoV/SARS-CoV-2 spike protein showed granular positivity in endothelial cells and epithelial cells of eccrine glands in both biopsies. All patients had an excellent outcome, and had minimal or no systemic symptoms. The coincidence of EM, a condition commonly related to viruses, and chilblains in the setting of COVID-19, and the positivity for SARS-CoV/SARS-CoV-2 spike protein by immunohistochemistry strongly suggest a link between EM-like lesions and SARS-CoV-2.

BACKGROUND: Different skin manifestations of COVID-19 are being reported. Acral lesions on the hands and feet, closely resembling chilblains, have been recognized during the peak incidence of the COVID-19 pandemic. MATERIAL AND METHODS: A retrospective review of 22 children and adolescents with chilblain-like lesions seen over a short period of time in the Emergency Department of a children's hospital during the peak incidence of COVID-19 in Madrid, Spain. RESULTS: All patients had lesions clinically consistent with chilblains of the toes or feet, with three also having lesions of the fingers. Pruritus and mild pain were the only skin symptoms elicited, and only 10 had mild respiratory and/or GI symptoms. None had fever. Coagulation tests, hemogram, serum chemistry, and lupus anticoagulant were normal in all patients tested. One out of 16 tested cases had elevated D-dimer results, but without systemic symptoms or other laboratory anomalies. SARS-CoV-2 PCR tested in 19 cases was positive in just one case. Skin biopsies obtained in six patients were consistent with chilblains. On follow-up, all cases showed spontaneous marked improvement or complete healing. CONCLUSION: Acute chilblains were observed during COVID-19 pandemic in children and teenagers. It is a mildly symptomatic condition with an excellent prognosis, usually requiring no therapy. Etiopathogenesis remains unknown.
