To analyze the outcomes of children with sickle cell disease (SCD) and COVID-19.
A multicenter prospective study was conducted in five hematological centers from Central and Southeast Brazil, ...starting in April 2020. The variables recorded include clinical symptoms, diagnostic methods, therapeutic measures, and treatment sites. The clinical repercussions of the infection on the initial treatment and the overall prognosis were also evaluated.
Twenty-five unvaccinated children, aged 4 to 17 years, with SCD and a positive SARS-CoV-2 RT-PCR result participated in this study. Patients were classified as SCD types SS (n = 20, 80%) and SC (n = 5, 20%). Clinical characteristics and evolution were similar in both groups (p>0.05), except for the fetal hemoglobin value which was higher among the SC patients (p = 0.025). The most frequent symptoms were hyperthermia (72%) and cough (40%). Three children were admitted to the intensive care unit, all of whom were overweight/obese (p = 0.078). No deaths were observed.
Although SCD leads to specific complications, the results found in this sample suggest that COVID-19 does not seem to carry an increased mortality risk in pediatric patients with this disease.

To describe two cases of patients who had thrombotic microangiopathy (TMA) associated with sickle cell disease (SCD).
Both patients started with a painful crisis and had acute chest syndrome during ...hospitalization. They showed significant worsening of hemolytic anemia, with very high levels of lactate dehydrogenase, thrombocytopenia, lowered level of consciousness, organ damage and the presence of schistocytes in peripheral blood. Due to the possibility of TMA, despite the very rare association with SCD, they were treated with fresh frozen plasma replacement and plasmapheresis, with good response.
TMA is a serious, life-threatening disease, characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ damage. The association of SCD and TMA is difficult to diagnose, since they can share a similar clinical presentation. Recognizing this association and promptly instituting treatment may impact the survival of these patients.

It is important to know if patients with hemoglobinopathy could be more susceptible to COVID-19.
Analyze SARS-CoV-2 infection in pediatric patients with hemoglobinopathy.
Using the online platforms ...LILACS, PUBMED and EMBASE, on 17- JUL-2020 a search was made for the terms COVID-19 and SARS-CoV-2 associated with “sickle cell”, “thalassemia” and “hemoglobinopathy”.
There were 623 pediatric and adult patients with sickle cell disease (SCD) or beta thalassemia (BT) and COVID-19. Total mortality rate was 6.42%. No pediatric patient with BT has been described. So, our analysis focused on children and adolescents with SCD: there were 121 pediatric patients, one adolescent died, prophylactic anticoagulation was prescribed to six patients, 11.76% needed intensive care unit, blood transfusion was prescribed in 29.70%. Vaso-occlusive crisis (VOC) and acute chest syndrome (ACS) were the main clinical manifestations in SCD.
Pediatric patients with SCD and COVID-19 have a low mortality rate when compared to adults, although is higher than the global pediatric population with COVID-19 (0−0.67%). The comorbidities associated with age and the long-term complications inherent to hemoglobinopathies may contribute to the increased mortality outside the pediatric age group. In SCD the clinical manifestations, both in children and adults, are VOC and ACS, and there was increase in blood requirement. Pediatric SCD patients with COVID-19 need more intensive care unit than the global pediatric population (3.30%).
Despite pediatric population with SCD needs more intensive care, the outcome after infection by COVID-19 is favorable.
To estimate trends in mortality rate and average age of death, and identify sociodemographic factors associated with early death in patients with sickle cell disease (SCD).
An ecological and ...cross-sectional study was conducted using data from the Mortality Information System. All deaths of patients residing in the state of São Paulo from 1996 to 2015 with at least one International Disease Code for SCD in any field of the death certificate were included. Simple linear regression was used to estimate trends. The Log-rank test and multiple Cox regression were used to identify factors associated with early death.
The age-standardized mortality rate per million inhabitants increased by 0.080 per year (R2=0.761; p<0.001). When the events were stratified by age at death, the increase was 0.108 per year for those occurring at age 20 years or older, (R2=0.789; p<0.001) and 0.023 per year for those occurring before age 20 years old (R2=0.188; p=0.056). The average age at death increased by 0.617 years (7.4 months) per year (R2=0.835; p<0.001). Sociodemographic factors associated with early death identified were male gender (hazard ratio - HR=1.30), white race (HR=1.16), death occurring in the hospital (HR=1.29), and living in the Greater São Paulo (HR=1.13).
The mortality rate and the average age of death in patients with SCD have increased over the last two decades. Sociodemographic factors such as gender, race, place of occurrence, and residence were found to be associated with early death.
Advances in medicine have increased the life expectancy of pediatric patients with chronic illnesses, and challenges with the guided transition of adolescents and young adults from pediatric clinics ...to adult clinics have grown. The aim of this study was to better understand readiness and factors related to this transition process in Brazil.
In this cross-sectional study of 308 patients aged from 16 to 21 years under follow-up in pediatric specialties, the degree of readiness for transition was assessed using the Transition Readiness Assessment Questionnaire (TRAQ) and its domains. Associations with demographic data, clinical data, socio-economic level, medication adherence, family functionality, and parental satisfaction with health care were evaluated.
The median TRAQ score was 3.7 (3.2 – 4.2). Better readiness was associated with female patients, socio-economic class A-B, current active employment, higher level of education, not failing any school year, attending medical appointments alone, functional family, and a good knowledge of disease and medications. A low correlation was observed between TRAQ and age. TRAQ presented good internal consistency (alpha-Cronbach 0.86). In the multiple linear regression, TRAQ score showed a significant association with female gender, advanced age, socio-economic class A-B, better knowledge of disease and medications, and independence to attend appointments alone.
TRAQ instrument can guide healthcare professionals to identify specific areas of approach, in order to support adolescents with chronic disease to set goals for their own personal development and improve their readiness to enter into the adult healthcare system. In this study, some factors were related to better TRAQ scores.
Sickle cell nephropathy begins in childhood and presents early increases in glomerular filtration, which, over the long term, can lead to chronic renal failure. Several diseases have increased ...circulating and urinary angiotensin-converting enzyme (ACE) activity, but there is little information about changes in ACEs activity in children with sickle cell disease (SCD).
We examined circulating and urinary ACE 1 activity in children with SCD.
This cross-sectional study compared children who were carriers of SCD with children who comprised a control group (CG). Serum and urinary activities of ACE were evaluated, as were biochemical factors, urinary album/creatinine rates, and estimated glomerular filtration rate.
Urinary ACE activity was significantly higher in patients with SCD than in healthy children (median 0.01; range 0.00-0.07 vs median 0.00; range 0.00-0.01 mU/mL·creatinine, p < 0.001. No significant difference in serum ACE activities between the SCD and CG groups was observed (median 32.25; range 16.2-59.3 vs median 40.9; range 18.0-53.4) mU/m`L·creatinine, p < 0.05.
Our data revealed a high urinary ACE 1 activity, different than plasmatic level, in SCD patients suggesting a dissociation between the intrarenal and systemic RAAS. The increase of urinary ACE 1 activity in SCD patients suggests higher levels of Ang II with a predominance of classical RAAS axis, that can induce kidney damage.
ABSTRACT Objective: To evaluate sociodemographic and clinical aspects of children with sickle cell disease (SCD) and their behavioral characteristics. Methods: Interview with parents of patients with ...SCD from four to ten years old, addressing socioeconomic aspects and other health conditions, and using the Strengths and Difficulties Questionnaire (SDQ). Clinical data were obtained from medical records. Exclusion criteria were the use of hydroxyurea, previous diagnosis of stroke, chronic encephalopathy and/or intellectual disability. Results: 45 patients (19 girls and 26 boys) were assessed. The median age was seven years. Diagnosis of SCD: 26 hemoglobinopathy SC; 19 hemoglobinopathy SS. Socioeconomic class: D: 24.4%; C2: 44.4%; C1: 28.9%; B2: 2.2%. Clinical history: acute chest syndrome: 40%; transfusions: 66.7%; hospitalizations: 82.2%. SDQ findings: 88.9% clinical impact (emotional subscale: 68.9%); total score: impact in 48.9%. It was not possible to establish a relation between the severity of the disease and the results of the SDQ. Regarding socioeconomic class: among individuals of classes B2 and C1, 21.4% had impact at the total score; in classes C2 and D, this percentage was 61.3%. Regarding the schooling of the head of the family, with Elementary School at least, 39.3% of the children had impacts; for fewer education, this percentage was 64.7%. Conclusions: Behavioral impacts are highly prevalent in children with SCD. Individuals in socioeconomic classes C2 and D suffered more behavioral impacts than individuals in classes B2 and C1.

Achados SDQ=88,9% alteração clínica (subescala emocional=68,9%); pontuação total=alterada em 48,9%. Não foi possível estabelecer relação entre gravidade da doença e os resultados do SDQ. Com relação à SES, entre indivíduos das classes B2 e C1, 21,4% tiveram alteração na pontuação total; nas classes C2 e D, esse percentual foi de 61,3%. Quanto à escolaridade do chefe da família, com no mínimo ensino fundamental completo, 39,3% das crianças tiveram alteração; para menor escolaridade, esse percentual foi 64,7%. Conclusões: Alterações comportamentais são altamente prevalentes em crianças com DF. Indivíduos das classes C2 e D tiveram mais alterações comportamentais em relação aos indivíduos das classes B2 e C1.
The aim of this study was to identify clinical and complete blood count differences between pediatric hospitalized patients with sickle cell disease infected or not by SARS-CoV-2 and compare the ...complete blood count of patients with sickle cell disease infected by SARS-CoV-2 before hospitalization and on admission.
This study was a single-center prospective cohort. Data were collected from medical records of pediatric inpatients with sickle cell disease under 18 years old infected or not with SARS-CoV-2 from the first visit to the hospital until discharge and from the last medical appointment. All patients were tested for SARS-CoV-2 by the real-time reverse transcription polymerase chain reaction.
Among 57 pediatric patients with sickle cell disease hospitalized from March to November 2020 in a Brazilian academic hospital, 11 (19.3%) had a positive result for SARS-CoV-2. Patients infected by SARS-CoV-2 had a higher prevalence of comorbidities than the ones who were not infected (63.6 vs. 30.4%; p=0.046). During hospital stay, no clinical or complete blood count differences between groups were found. There was a decrease in eosinophil count on hospital admission in patients with sickle cell disease infected by SARS-CoV-2 (p=0.008).
Pediatric hospitalized patients with sickle cell disease infected by SARS-CoV-2 had more comorbidities and had a decrease in eosinophil count between hospital admission and the last medical appointment.
