Clinical analysis of 17 cases of neonatal lupus erythematosus / 中国小儿急救医学

Objective:To summarize the clinical features of neonatal lupus erythematosus(NLE) and improve the understanding of the disease.Methods:The clinical data of 17 NLE neonates admitted to the First Affiliated Hospital of Zhengzhou University from February 2015 to September 2021 were retrospectively analyzed, and relevant literatures were reviewed.Results:Of the 17 patients, nine were boys and eight were girls.There were 13 cases of skin damage and eight cases of heart damage, including four cases of atrioventricular block, one case of QT interval prolongation complicated with atrial premature beat, three cases of atrial septal defect, one case of ventricular septal defect, two cases of patent ductus arteriosus, one case of pericardial effusion, one case of pulmonary hypertension, and two cases of cardiac insufficiency.One case developed skin damage and heart block at the same time.There were 15 patients with blood system damage and 11 patients with hepatobiliary system damage.Among the serological indicators, 17 cases were positive for anti-ANA antibody, 12 cases were positive for anti-SSA-60, 13 cases were positive for anti-SSA-52, seven cases were positive for SSB, one case was positive for Sm, and three cases were positive for RNP.Among them, four neonates with atrioventricular block were positive for anti-SSA-60 and anti-SSA-52.Most of the patients with skin lesions had good prognosis, and only one patient had brown scars, one neonate with second-degree type Ⅱ atrioventricular block and one neonate with QT interval prolongation combined with premature atrial contractions had normal electrocardiograms.Additionally, two patients still had third-degree atrioventricular block, and the other one patient was installed with a pacemaker at one year and two months, and left spastic cerebral palsy.A total of 16 mothers had serological tests, among which ten cases had abnormal connective tissue antibodies before delivery and six cases had abnormal connective tissue antibodies after delivery.Conclusion:There is no significant gender difference in NLE, third-degree atrioventricular block is difficult to reverse, and most patients with extracardiac damage have a good prognosis.

Avaliação da estimulação ventricular direita crônica em crianças e adultos jovens com bloqueio atrioventricular congênito isolado / Evaluation of chronic right ventricular pacing in children and young adults with isolated congenital complete atrioventricular block

Introdução: O bloqueio atrioventricular congênito isolado (BAVCi) é raro e tem múltiplas apresentações clínicas. O implante de marca-passo cardíaco permanente (MP) é o tratamento de escolha, resultando em evolução clínica satisfatória para a maioria dos casos, porém, aproximadamente 10% deles apresentam remodelamento ventricular e insuficiência cardíaca grave. Objetivos: Estudar a evolução tardia de crianças e adultos jovens com BAVCi e estimulação crônica do ventrículo direito (VD), visando determinar: a prevalência de sinais clínicos e laboratoriais de insuficiência cardíaca e de remodelamento ventricular; a capacidade funcional; a qualidade de vida e fatores preditores de alterações clínicas, funcionais ou ecocardiográficas. Métodos: Estudo transversal realizado em coorte de portadores de BAVCi e MP implantado antes de 21 anos de idade com estimulação no VD há mais de um ano. Todos os indivíduos foram submetidos a avaliação clínica e laboratorial, da capacidade funcional, da qualidade de vida e a ecocardiograma. Mães e sujeitos da pesquisa foram investigados para doenças reumatológicas. Os dados foram armazenados no sistema REDCap (Research Electronic Data Capture) e analisados pelos programas SAS (Statistical Analysis System), SPSS (Statistical Package for the Social Sciences) e R Studio. A análise dos dados incluiu: análise univariada para pesquisa de associações entre variáveis preditoras e desfechos, coeficiente de correlação de Pearson e modelo de regressão linear multivariado. Resultados: De março/2010 a dezembro/2013, foram avaliados 63 indivíduos, 68% do sexo feminino, com idade de 1 a 40 anos, com MP por 13,4 ± 6,5 anos e estimulação do VD por 10,0 ± 5,4 anos. O modo de estimulação era atrioventricular em 55,6%, o percentual de estimulação de VD de 97,9 ± 4,2% e a duração do complexo QRS estimulado de 152,4 ± 20,1 ms. A maioria (88,9%) era assintomática e não utilizava medicamentos de ação cardiovascular. Maior tempo de MP...

Introduction: Isolated congenital atrioventricular block (iCAVB) is a rare condition with multiple clinical presentations. Permanent cardiac pacing is the most effective therapy for this population resulting in satisfactory long-term outcomes. However, approximately 10% of patients may have ventricular remodeling and severe heart failure. Objectives: To study the long-term effects of chronic right ventricular (RV) pacing in children and young adults with iCAVB in order to determine: prevalence of clinical and laboratory signs of heart failure and ventricular remodeling, functional capacity, quality of life and predictors of clinical, functional or echocardiographic abnormalities. Methods: Cross-sectional study of a cohort of iCAVB patients with <= 21 years old at initial pacemaker (PM) implantation and single or dual-chamber pacing in a unique RV site for a minimum of one year. All subjects underwent clinical and laboratory assessment, functional capacity, quality of life and echocardiogram. Mothers and research subjects were investigated for rheumatic diseases. Data were stored in REDCap (Research Electronic Data Capture) system and analyzed by SAS (Statistical Analysis System), SPSS (Statistical Package for the Social Sciences) and R Studio programs. Data analysis included: univariate analysis for associations between predictor variables and outcomes, Pearson correlation coefficient and linear regression multivariate model. Results: Between March/2010 and December/2013, we evaluated 63 subjects aged 1-40 years old, 68% female, under PM for 13.4 ± 6.5 years and under RV pacing for 10.0 ± 5.4 years. Pacing mode was atrioventricular in 55.6%, percentage of RV pacing was 97.9 ± 4.2% and paced QRS duration was 152.4 ± 20.1 ms. Overall, the majority (88.9%) were asymptomatic and did not use cardiovascular drugs. Longer time under PM (P= 0.013), or even under RV pacing (P= 0.005), higher age at study inclusion (P= 0.032) and lower left ventricular...

Profile of glomerular diseases in a public hospital of Federal District, Brazil / Perfil das doenças glomerulares em um hospital público do Distrito Federal

INTRODUÇÃO: As doenças glomerulares são uma causa frequente de doença renal crônica, sobretudo nos países em desenvolvimento. OBJETIVO: O objetivo deste estudo foi determinar o perfil destas glomerulopatias em um hospital público da cidade de Brasília, Distrito Federal. MÉTODOS: Foram realizadas 121 biopsias renais pela equipe de nefrologia do Hospital Regional da Asa Norte (HRAN) entre agosto de 2005 e maio de 2009. Foram excluídas oito biopsias realizadas em pacientes transplantados renais e analisados os prontuários dos 113 pacientes restantes. Dados analisados: sexo, idade, exames laboratoriais, síndrome glomerular, diagnóstico clínico, grau de fibrose intersticial, uso de imunossupressores, necessidade de diálise e desfecho clínico. RESULTADOS: A média de idade foi 34,9 ± 16,2 anos, com predomínio masculino (51,3 por cento). As principais síndromes glomerulares foram: síndrome nefrótica (41,6 por cento) e glomerulonefrite rapidamente progressiva (35,4 por cento). Entre as glomerulopatias primárias, houve predomínio da glomeruloesclerose segmentar e focal (26,9 por cento) e da nefropatia por IgA (25 por cento) e entre as secundárias a nefrite lúpica (50 por cento) e a glomerulonefrite proliferativa exsudativa difusa (34,2 por cento). A maioria dos pacientes fez uso de imunossupressores (68,1 por cento) e quase um terço deles (29,2 por cento) necessitou de diálise durante a internação. Evoluíram para terapia dialítica crônica 13,3 por cento dos pacientes e 10,6 por cento evoluíram a óbito. CONCLUSÃO: Este estudo poderá contribuir para melhor entendimento epidemiológico das doenças glomerulares no Distrito Federal, orientando na adoção de políticas públicas visando permitir rápido diagnóstico e manejo clínico das mesmas.

INTRODUCTION: Glomerular diseases are a frequent etiology of chronic kidney disease, especially in the developing countries. OBJECTIVE: To determine the profile of such glomerulopathies in a public hospital located in the city of Brasilia, Federal District. METHODS: 121 renal biopsies in different patients were performed by the Renal Division of Hospital Regional da Asa Norte (HRAN) between August 2005 and May 2009. Eight renal biopsies in renal-transplant patients were excluded and the medical records of 113 remaining patients were analyzed. Analyzed data: sex, age, laboratory exams, glomerular syndrome, clinical diagnosis, degree of interstitial fibrosis, immunosuppressants use, need for dialysis and clinical outcome. RESULTS: The age average was 34.9 ± 16.2 years-old, a predominance of male patients (51.3 percent). Major glomerular syndromes were: nephrotic syndrome (41.6 percent) and the rapidly- progressive glomerulonephritis (35.4 percent). Among primary glomerulopathies focal glomerulosclerosis (26.8 percent) followed by IgA nephropathy (25 percent) were predominant; and among the most prevalent secondary glomerulopathies we had lupus nephritis (50 percent) and diffuse exudative proliferative glomerulonephritis (34.2 percent).The majority of the patients used immunosuppressants (68.1 percent) and almost one third of them (29.2 percent) needed dialysis during their hospitalization. Progressed to chronic dialysis therapy 13.3 percent of the patients and 10.6 percent died. CONCLUSION: This study may contribute to better epidemiological understanding of glomerular diseases in the Federal District, guiding the adoption of public policies aiming the quick clinical treatment of such diseases.

A case of neonatal lupus syndrome with congenital complete heart block / 대한산부인과학회잡지

The neonatal lupus syndrome is characterized by skin lesions, hepatic and hematologic abnormalities and congenital heart block. Congenital heart block which is believed to be caused by transplacental passage of the anti-Ro (SSA)/La (SSB) antibodies from mother to infant, is known to occur in 1 in 20,000 live births. In contrast to other manifestation of neonatal lupus syndrome, which usually subside within 6 months after birth, congenital heart block is a permanent and potentially fatal complication. We experienced a case of neonatal lupus syndorme with congenital complete heart block in a newborn of asyptomatic mother with anti-Ro (SSA)/ La (SSB) antibodies.
