Abstract:
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.
