Background: Transient erythroblastopenia of childhood (TEC) is an acquired, self-limited pure red cell aplasia that usually occurs in children 4 years old and younger. This clinical condition has been priorly described to be linked to numerous viral and immunologic mechanisms. COVID-19, caused by the coronavirus SARS-CoV-2, was initially discovered in China in December 2019. The disease quickly spread worldwide, resulting in pandemic., Case Presentation: This manuscript reports a new clinically relevant condition associated to COVID-19, describing a child with clinical and biochemical signs of Pure Red Blood cells aplasia and complete absence of erythroblasts at the bone marrow needle aspiration with signs of erythrophagocytosis, resembling morphological signs such as in hemophagocytic lymphohistiocytosis (HLH), temporally associated to SARS-CoV-2 infection., Conclusion: This report highlights a newly described continuum laboratory and clinical spectrum of immune/hematological dysregulations secondary to SARS-CoV-2. SARS-CoV-2 infection-linked TEC has never been described in literature, but, according to our findings, should be considered in all the patients with transient erythroblastopenia without congenital red blood cell abnormalities and serology negative for major infections associated with TEC. This condition must be considered in the same spectrum of MIS-C and the inter-links among the two clinical manifestations, as well as a potential interdependence among them, should be considered in the future., (© 2024.

Background: Increased incidence of central precocious puberty (CPP) after coronavirus infectious disease-19 lockdown has been reported. Our study aims in investigating changes in CPP rates and in sleep patterns in CPP and healthy controls., Methods: CPP were retrospectively evaluated from April 2020 to April 2021. Parents of girls diagnosed with CPP during lockdown and of matched healthy controls filled out a questionnaire about sleep disturbances (SDSC questionnaire) and sleep schedules., Results: Thirty-five CPP and 37 controls completed the survey. Incidence of new CPP cases significantly increased in 2020-2021 compared to 2017-2020 (5:100 vs 2:100, p = 0.02). Sleep disturbance rates did not differ between CPP and healthy controls before lockdown. During lockdown, CPP reported higher rates of sleep disturbs for total score (p = 0.005), excessive somnolence (p = 0.049), sleep breathing disorders (p = 0.049), and sleep-wake transition disorders (p = 0.005). Moreover, CPP group more frequently shifted toward later bedtime (p = 0.03) during lockdown compared to controls. Hours of sleep and smartphone exposure around bedtime did not differ between groups., Conclusions: Our study confirms the observation of increased incidence of CPP after lockdown measures. Additionally, CPP showed higher rates of sleep disturbances and later bedtime compared to controls. The causality link between sleep disturbances and CPP should be further investigated to gain knowledge in this association., (© 2022. The Author(s).)

The rapid global spread of coronavirus disease 2019 (COVID-19) infection has become a major health issue with higher morbidity and mortality rates. Besides respiratory symptoms, a growing body of evidence indicates a variety of gastrointestinal manifestations including liver involvement. In this regard, several data supported an association between COVID-19 infection and liver injury in adults, while in children there is compelling but currently limited evidence. In particular, patients with COVID-19 have shown a higher risk of liver injury (mainly expressed as increased transaminase levels or hepatic steatosis). Conversely, a greater risk of more severe forms of COVID-19 infection has been observed in subjects with pre-existing chronic liver diseases. The dramatic interplay between COVID-19 and liver damage has been related to the inflammatory pathways chronically active in patients with nonalcoholic fatty liver disease and acutely in those affected by COVID-19, but other different pathogenic mechanisms have also been supposed. Of note, patients with previous metabolic comorbidities also had a higher risk of severe COVID-19 infection. This emphasizes the pathogenic interrelation of the inflammatory pathways with a dysregulated metabolic milieu in COVID-19 patients. Taking into account the prognostic role of fatty liver in COVID-19 patients and its intrinsic relationship with metabolic abnormalities even in childhood, a strict monitoring of this condition is recommended. We aimed to summarize the most recent evidence regarding the potential interplay between pediatric fatty liver and COVID-19., Competing Interests: Conflict-of-interest statement: The authors have no conflict of interest to declare., (©The Author(s) 2021.
