RESUMEN
BACKGROUND: Acute kidney injury (AKI) is common in the pediatric intensive care unit (ICU) and is associated with poorer clinical outcomes. There is scarce data to support an association between nutritional status and nutrient delivery in critically ill pediatric patients. Therefore, the present study aimed to identify the nutritional and clinical factors associated with the development of AKI during pediatric ICU stay. METHODS: This prospective study included critically ill pediatric patients aged < 15 years who were admitted to the medical and surgical pediatric ICU. Clinical, laboratory, nutritional status, nutritional therapy parameters, and AKI data were recorded. Adjusted logistic regression was applied and expressed as odds ratio (OR) and 95% confidence interval (95%CI). P-value < 0.05 was considered significant. RESULTS: We enrolled 108 patients with a median age of 9 months (interquartile range/IQR 2.4-62.5), and 43.5% developed AKI. Sepsis/septic shock (OR 8.00; 95% CI 2.06-32.51, p = 0.003), higher severity of illness (OR 1.89; 95% CI 1.24-2.90, p = 0.003), hypoalbuminemia (OR 4.11; 95% CI 1.61-10.46, p = 0.006), edema (OR 3.42, 95% CI 1.10-10.67, p = 0.034), fluid overload (OR 3.52, 95% CI 1.56-7.96, p = 0.003), need for mechanical ventilation (OR 3.62, 95% CI 1.45-9.04, p = 0.006) and adequate protein intake (OR 0.79, 95% CI 0.63-1.00, p = 0.048) were associated with development of AKI. CONCLUSIONS: Hypoalbuminemia, need for mechanical ventilation, fluid overload, severity of illness, sepsis/septic shock, and edema were risk factors for AKI in pediatric ICU. Furthermore, adequate protein intake is associated with AKI during pediatric ICU stay, making it important to implement nutritional assessment and nutritional therapy protocols for critically ill pediatric patients.

ABSTRACT The covid-19 vaccine confers direct protection and reduces transmission rates of the virus and new variants. Vaccines from Pfizer/BioNTech and CoronaVac have been cleared for children in Brazil. They are safe, effective, and immunogenic. There are no known complications associated with the use of steroids or vaccines in pediatric patients with covid-19 and nephrotic syndrome. With or without immunosuppression, these patients are not at increased risk of severe covid-19, and steroids are safe for them. A milder form of covid-19 occurs in patients with chronic kidney disease without the need for hospitalization. The vaccine response may be reduced and/or the duration of antibodies after vaccination may be shorter than in the general population. However, considering risk of exposure, vaccination against covid-19 is recommended. It is believed that patients with hemolytic-uremic syndrome are at higher risk of severe covid-19. Vaccination is recommended, although specific data on the safety and efficacy of the covid-19 vaccine are limited. There is agreement that the benefits of induced immunity outweigh the risks of immunization. Vaccination against covid-19 is recommended for children and adolescents needing kidney transplantation or who have undergone transplantation. These patients present decreased immune response after vaccination, but immunization is recommended because the benefits outweigh the risks of vaccination. Current recommendations in Brazil stipulate the use of the messenger RNA vaccine. This paper aims to provide pediatric nephrologists with the latest knowledge about vaccination against covid-19 for children with kidney disease.
Resumo A vacina covid-19 confere proteção direta, reduz as taxas de transmissão do vírus e de novas variantes. No Brasil, estão liberadas para a população pediátrica as vacinas Pfizer/BioNTech e a CoronaVac, ambas seguras, eficazes e imunogênicas. Pacientes pediátricos com síndrome nefrótica e covid-19 têm curso clínico regular sem complicações relacionadas ao uso de esteroides ou vacinas. Esses pacientes, com ou sem imunossupressão, não apresentam maior risco de covid-19 grave e o tratamento com esteroides é seguro. Os pacientes com doença renal crônica têm covid-19 mais leve, sem necessidade de hospitalização. A resposta vacinal pode ser reduzida e/ou a duração dos anticorpos pós-vacinação pode ser menor do que na população geral. Entretanto, a vacina covid-19 está recomendada, considerando o risco de exposição. Acredita-se que pacientes com síndrome hemolítico-urêmica teriam maior risco de covid-19 grave. A vacina é recomendada, embora dados específicos sobre segurança e eficácia da vacina covid-19 sejam limitados. Há concordância que os benefícios da imunidade induzida superam quaisquer riscos da imunização. A vacina covid-19 é recomendada para crianças e adolescentes candidatos ao transplante renal ou já transplantados. Esses pacientes têm resposta imunológica reduzida após a vacina, entretanto ela é recomendada porque os benefícios superam qualquer risco dessa vacinação. A recomendação atual no Brasil é a vacina de tecnologia RNA mensageiro. O objetivo deste documento é levar aos nefrologistas pediátricos os conhecimentos mais recentes sobre a vacinação contra contra-19 em crianças com doenças renais.

RESUMEN
Background: Atypical hemolytic uremic syndrome (aHUS) is an ultra-rare disease. Therefore, studies involving large samples are scarce, making registries powerful tools to evaluate cases. We present herein the first analysis of the Brazilian aHUS Registry (BRaHUS). Methods: Analysis of clinical, laboratory, genetic and treatment data from patients inserted in the BRaHUS, from 2017 to 2020, as an initiative of the Rare Diseases Committee of the Brazilian Society of Nephrology. Results: The cohort consisted of 75 patients (40 adults and 35 pediatric). There was a predominance of women (56%), median age at diagnosis of 20.7 years and a positive family history in 8% of cases. Renal involvement was observed in all cases and 37% had low C3 levels. In the <2 years of age group, males were predominant. Children presented lower levels of hemoglobin (P = .01) and platelets (P = .003), and higher levels of lactate dehydrogenase (LDH) (P = .004) than adults. Genetic analysis performed in 44% of patients revealed pathogenic variants in 66.6% of them, mainly in CFH and the CFHR1-3 deletion. Plasmapheresis was performed more often in adults (P = .005) and 97.3% of patients were treated with eculizumab and its earlier administration was associated with dialysis-free after 3 months (P = .08). Conclusions: The cohort of BRaHUS was predominantly composed of female young adults, with renal involvement in all cases. Pediatric patients had lower hemoglobin and platelet levels and higher LDH levels than adults, and the most common genetic variants were identified in CFH and the CFHR1-3 deletion with no preference of age, a peculiar pattern of Brazilian patients.

Abstract Introduction: Kidney transplant recipients (KTR) are at increased risk for dengue virus (DENV) infection. The aim of this study was to outline the clinical presentation and laboratory profile of DENV infection in KTR and its impact on renal function. Methods: This was a retrospective study of KTR diagnosed with DENV infection. Adult patients who visited Santa Casa de Belo Horizonte Nephrology Center between April and September 2019 were included. Patients who did not sign the Informed Consent were excluded. Data were collected from the database and medical records. The study was approved by the local Institutional Ethics Committee and the Informed Consent was obtained. Results: Nineteen KTR were evaluated. The main signs and symptoms were myalgia, headache/retro-orbital pain, fever, and gastrointestinal symptoms. Two patients had acute cholecystitis without calculus, three experienced pleural and/or pericardial effusion, and one developed acute myocarditis. All patients were under immunosuppression with prednisone, tacrolimus, and mycophenolate, and most were not receiving induction therapy. Temporary suspension/reduction of immunosuppression was required in 58% of patients and leukopenia was the most common reason. Thrombocytopenia was common and 58% of patients developed acute kidney injury. All patients recovered renal function. Conclusions: DENV infection in KTR patients seems to follow a similar course as in the general population. Although there was no control group, we suspect that immunosuppression, preexisting kidney disease or type of donor was not a determining factor in most patients. Transient renal dysfunction was common but reversible. No patient experienced death or graft loss.
Resumo Introdução: Receptores de transplante renal (RTR) apresentam maior risco de infecção pelo vírus da dengue (DENV). O objetivo deste estudo foi delinear apresentação clínica e perfil laboratorial da infecção por DENV em RTR e seu impacto na função renal. Métodos: Este foi um estudo retrospectivo de RTR diagnosticados com infecção por DENV. Incluiu-se pacientes adultos que estiveram no Centro Nefrológico da Santa Casa de Belo Horizonte entre Abril/Setembro, 2019. Foram excluídos pacientes que não assinaram o Termo de Consentimento Livre e Esclarecido. Dados foram coletados do banco de dados e registros médicos. O estudo foi aprovado pelo Comitê de Ética Institucional local e obteve-se o Consentimento Livre e Esclarecido. Resultados: Avaliou-se dezenove RTR. Principais sinais e sintomas foram mialgia, cefaleia/dor retro-orbital, febre, sintomas gastrointestinais. Dois pacientes apresentaram colecistite aguda sem cálculo, três sofreram derrame pleural e/ou pericárdico, um desenvolveu miocardite aguda. Todos os pacientes estavam sob imunossupressão com prednisona, tacrolimus, micofenolato. A maioria não estava recebendo terapia de indução. Suspensão/redução temporária da imunossupressão foi necessária em 58% dos pacientes e leucopenia foi a razão mais comum. Trombocitopenia foi comum e 58% dos pacientes desenvolveram lesão renal aguda. Todos recuperaram a função renal. Conclusões: A infecção por DENV em pacientes RTR parece seguir um curso semelhante ao da população em geral. Embora não houvesse grupo controle, suspeitamos que imunossupressão, doença renal preexistente ou tipo de doador não foram fator determinante na maioria dos pacientes. Disfunção renal transitória foi comum, mas reversível. Nenhum paciente veio ao óbito ou sofreu perda do enxerto.

The incidence of urolithiasis (UL) is increasing, and it has become more common in children and adolescents over the past few decades. Hypercalciuria is the leading metabolic risk factor of pediatric UL, and it has high morbidity, with or without lithiasis as hematuria and impairment of bone mass. The reduction in bone mineral density has already been described in pediatric idiopathic hypercalciuria (IH), and the precise mechanisms of bone loss or failure to achieve adequate bone mass gain remain unknown. A current understanding is that hypercalciuria throughout life can be considered a risk of change in bone structure and low bone mass throughout life. However, it is still not entirely known whether hypercalciuria throughout life can compromise the quality of the mass. The peak bone mass is achieved by late adolescence, peaking at the end of the second decade of life. This accumulation should occur without interference in order to achieve the peak of optimal bone mass. The bone mass acquired during childhood and adolescence is a major determinant of adult bone health, and its accumulation should occur without interference. This raises the critical question of whether adult osteoporosis and the risk of fractures are initiated during childhood. Pediatricians should be aware of this pediatric problem and investigate their patients. They should have the knowledge and ability to diagnose and initially manage patients with IH, with or without UL.
RESUMEN
BACKGROUND: Hypercalciuria is the most common metabolic risk factor for calcium urolithiasis and is associated with bone loss in adult patients. Reduced bone mineral density (BMD) was already described in idiopathic hypercalciuria (IH) children, but the precise mechanisms of bone loss or inadequate bone mass gain remain unknown. Life-long hypercalciuria might be considered a risk to change bone structure and determine low bone mass throughout life. The peak of bone mass should occur without interferences. A beneficial effect of citrate formulations and thiazides on bone mass in adult and pediatric patients with IH have been shown. AIM: To evaluate whether pharmacological therapy has a beneficial effect on bone mass in children and adolescents with IH. METHODS: This retrospective cohort study evaluated 40 hypercalciuric children non-responsive to lifestyle and diet changes. After a 2-mo run-in period of citrate formulation (Kcitrate) usage, the first bone densitometry (DXA) was ordered. In patients with sustained hypercalciuria, a thiazide diuretic was prescribed. The second DXA was performed after 12 mo. Bone densitometry was performed by DXA at lumbar spine (L2-L4). A 24-h urine (calcium, citrate, creatinine) and blood samples (urea, creatinine, uric acid, calcium, phosphorus, magnesium, chloride, hemoglobin) were obtained. Clinical data included age, gender, weight, height and body mass index. RESULTS: Forty IH children; median age 10.5 year and median time follow-up 6.0 year were evaluated. Nine patients were treated with Kcitrate (G1) and 31 with Kcitrate + thiazide (G2). There were no differences in age, gender, body mass index z-score and biochemical parameters between G1 and G2. There were no increases in total cholesterol, kalemia and magnesemia. Calciuria decreased in both groups after treatment. Lumbar spine BMD z-score increased after thiazide treatment in G2. There was no improvement in G1. CONCLUSION: Results point to a beneficial effect of thiazide on lumbar spine BMD z-score in children with IH. Further studies are necessary to confirm the results of the present study.
RESUMEN
Abstract The reported cases describe the association between collapsing focal segmental glomerulosclerosis (FSGS) and acute dengue virus infection. In both cases, patients were diagnosed with dengue virus infection and had a severe kidney disease, with nephrotic syndrome and acute kidney injury. Kidney biopsy was performed and showed collapsing FSGS. The first patient, a 27-year-old man, was diagnosed with dengue virus infection and developed nephrotic syndrome after two weeks of illness. He was treated with methylprednisolone for three days and intravenous furosemide. This patient evolved well, although his renal function did not fully recover. The second patient, a 32-year-old man, was diagnosed with a milder clinical presentation of dengue virus infection. He had a past medical history of nephrotic syndrome in childhood, which might have caused its relapse. This patient was treated with intravenous furosemide and also did not fully recover renal function. These cases highlight the possible implication of dengue virus infection in the etiology of collapsing variant of FSGS. Healthcare professionals should be prepared to identify similar cases.
Resumo Os casos relatados descrevem a associação entre glomeruloesclerose segmentar e focal (GESF) colapsante e infecção aguda pelo vírus da dengue. Nas duas instâncias os pacientes foram diagnosticados com infecção pelo vírus da dengue e apresentaram doença renal grave, com síndrome nefrótica e insuficiência renal aguda. A biópsia renal revelou a presença de GESF colapsante. O primeiro paciente, um homem de 27 anos, foi diagnosticado com infecção pelo vírus da dengue e desenvolveu síndrome nefrótica após duas semanas de doença. Ele foi tratado com metilprednisolona por três dias e furosemida endovenosa. O paciente evoluiu bem, embora sua função renal não tenha se recuperado plenamente. O segundo paciente, um homem de 32 anos, foi diagnosticado com apresentação clínica mais discreta de infecção pelo vírus da dengue. Ele tinha histórico de síndrome nefrótica na infância, o que pode ter causado a recidiva. O paciente foi tratado com furosemida endovenosa e também não recuperou plenamente sua função renal. Os dois casos destacam a possível implicação da infecção pelo vírus da dengue na etiologia da variante colapsante da GESF. Os profissionais de saúde devem estar preparados para identificar casos semelhantes.

INTRODUCTION: The impact of the new coronavirus (SARS-COV-2) and its worldwide clinical manifestations (COVID-19) imposed specific regional recommendations for populations in need of specialized care, such as children and adolescents with kidney diseases, particularly in renal replacement therapies (RRT). We present the recommendations of the Brazilian Society of Nephrology regarding the treatment of pediatric patients with kidney diseases during the COVID-19 pandemic. METHODS: Articles and documents from medical societies and government agencies on specific recommendations for children on RRT in relation to COVID-19 as well as those focused on epidemiological aspects of this condition in Brazil Were evaluated and analyzed. RESULTS: We present recommendations on outpatient care, transportation to dialysis centers, peritoneal dialysis, hemodialysis, and kidney transplantation in children and adolescents during the COVID-19 pandemic in Brazil. DISCUSSION: Despite initial observations of higher mortality rates in specific age groups (the elderly) and with comorbidities (obese, diabetics, and those with cardiovascular diseases), patients with chronic kidney disease (CKD) on RRT are particularly prone to develop COVID-19. Specific measures must be taken to reduce the risk of contracting SARS-CoV-2 and developing COVID-19, especially during transport to dialysis facilities, as well as on arrival and in contact with other patients.

During the Covid-19 pandemic, the issue is how to maintain adequate care for people with other diseases. In this document, the SBN Rare Diseases Committee (COMDORA) gives some guidelines on the care of patients with rare kidney diseases. These patients should follow the recommendations for the general population, bearing in mind that, as they have chronic kidney disease, they are included in the risk group for more serious outcomes if they develop Covid-19. Non-essential decision-making procedures should be postponed. In stable cases under appropriate treatment, we must choose to contact our patients remotely, using teleconsultations and home exam collections (if possible). In the presence of a symptom or sign of decompensation of the underlying disease, or infection with Sars-cov-2, advise the patient to seek medical assistance. The patient should not be waiting to get worse. Changes to the prescription should only be made on a scientific basis. Dosage suspension or change is not recommended, even in cases in which the patient needs to go to a center to receive his medication; in this case, the infusion center must follow the recommendations of the Ministry of Health. If the patient develops Covid-19 and uses any drugs, check the need for dose adjustment of the routine medications. Avoid the use of antimetabolics and anti-CD20 in patients with Covid-19, as they reduce viral clearance and predispose to bacterial infections. Contact between the patient and the medical team is essential; changes are recommended only with specialized medical guidance.

RESUMO Introdução O impacto do novo coronavírus (SARS-CoV-2) e as suas manifestações clínicas (Covid-19) em todo o mundo impôs recomendações regionais específicas a populações que necessitam de cuidados especializados, como crianças e adolescentes com doenças renais, particularmente em terapias de substituição renal (TRS). Apresentamos as recomendações da Sociedade Brasileira de Nefrologia em relação ao tratamento de pacientes pediátricos com doenças renais durante a pandemia Covid-19. Método Foram avaliados e analisados os artigos e documentos sobre recomendações específicas para Covid-19 de sociedades médicas e órgãos governamentais sobre crianças em TRS, bem como aqueles focados em aspectos epidemiológicos dessa condição no Brasil. Resultados Apresentamos as recomendações sobre atendimento ambulatorial, transporte para centros de diálise, diálise peritoneal, hemodiálise e transplante renal em crianças e adolescentes durante a pandemia de Covid-19 no Brasil. Discussão Apesar das observações iniciais de taxas de mortalidade mais altas em grupos etários específicos (idosos) e com comorbidades (obesos, diabéticos e aqueles com doenças cardiovasculares), pacientes com doença renal crônica (DRC) em TRS apresentam risco significativo de evoluir com Covid-19. Medidas específicas devem ser tomadas para reduzir o risco de contrair SARS-CoV-2 e desenvolver a Covid-19, principalmente durante o transporte para instalações de diálise, bem como na chegada e no contato com outros pacientes.

RESUMO Durante a pandemia da Covid-19, fica a questão de como manter o atendimento adequado aos portadores de outras doenças. O Comitê de Doenças Raras (COMDORA) da SBN neste documento dá algumas orientações ao atendimento de pacientes com doenças renais raras. Estes pacientes devem seguir as recomendações destinadas à população geral tendo em mente que, por serem portadores de doença renal crônica, estão incluídos no grupo de risco para desfechos mais graves, caso venham a desenvolver a Covid-19. Procedimentos não essenciais para tomada de decisão devem ser adiados. Deve-se optar por contatos a distância, como teleconsultas, e coletas de exames domiciliares (se possível) nos casos estáveis sob tratamento adequado. Na presença de sintoma ou sinal de descompensação da doença de base ou infecção pelo Sars-cov-2, orientar o paciente a procurar a equipe médica. O paciente não deve ficar esperando o quadro agravar-se. Alterações na prescrição só devem ser feitas com embasamento científico. Não se recomenda a suspensão ou alteração posológica, mesmo nos casos em que o paciente necessita ir a um centro para receber sua medicação; neste caso o centro de infusão deve seguir as recomendações do Ministério da Saúde. Caso o paciente desenvolva a Covid-19 e faça uso de alguma droga, verificar a necessidade de ajuste nas doses dos medicamentos rotineiros. Evitar o uso de antimetabólicos e antiCD20 nos pacientes com a Covid-9, por reduzirem o clareamento viral e predisporem a infecções bacterianas. O contato entre paciente e equipe médica é essencial; alterações são recomendadas apenas com orientação médica especializada.

AIM: To investigate the prevalence of nutritional parameters of risk for cardiovascular disease (CVD) and kidney diseases in healthy preschool children. METHODS: This is an observational cross-sectional study with 60 healthy children, of both genders, aged two to six years old and 56 mothers, in Belo Horizonte, Minas Gerais, Brazil. Preschool children and their families with regular activities at public schools were invited to paticipate in the study. The following characteristics were assessed: Socio-demographic condictions, clinical health, anthropometric, biochemical, lifestyle and data on food consumption. The 56 healthy children were divided into two groups, overweight (C1) and non-overweight (C2), as well as their mothers, respectively, in overweight (M1) and non-overweight (M2). Nutritional status was defined according to results obtained through the Anthro® Software for nutritional analysis. RESULTS: Thirty-five children were male, with mean age of 4.44 ± 1.0 years old. Eighty-nine percent of them were eutrophic, 86.7% were sedentary and they had five meals a day. Body mass index (BMI) for age and total cholesterol (TC) was higher on C1 (P = 0.0001) and high density lipoprotein cholesterol (HDL-c) was higher on C2. Mothers were 32.5 ± 7.1 years old, mostly married and employed. Eighty-six percent of them were sedentary and 62.5% were overweight with BMI = 26.38 ± 5.07 kg/m2. Eighteen percent of the overweight mothers had isolated total hypercholesterolemia (TC levels elevated) and 12.5% had low HDL-c levels. The present study showed an association between overweight and obesity during the preschool years and the correspondent mothers' nutritional status of overweight and obesity (OR = 4.96; 95%CI: 0.558-44.17). There was a positive correlation between the food risk associated with CVD by children and mothers when their consumption was 4 times/wk (P = 0.049; r = 0.516) or daily (P = 0.000008; r = 0.892). CONCLUSION: Analyzed children showed high rates of physical inactivity, high serum cholesterol levels and high consumption of food associated with risk for CVD and renal disease. Changes in habits should be encouraged early in kindergarten.
