Severe Early Congenital Syphilis with Multiorgan Involvement in a Preterm Neonate: A Case Report

Background and Clinical Significance: Lues remains a global health concern despite the well-known nature of its symptoms, the availability of diagnostic methods, and the existence of effective therapy. The recent increase in maternal syphilis has been accompanied by a rise in congenital infections, which are associated with stillbirth, prematurity, neonatal mortality, and severe multisystemic disorder. In newborns, it may present with highly variable clinical manifestations, making timely diagnosis and treatment essential. We report a case of severe early congenital syphilis in a premature newborn with extensive multiorgan involvement; Case Presentation: We present a case of a male infant born at 31 + 6 weeks of gestation to a 26-year-old mother with inadequate antenatal care and no documented screening or treatment for syphilis during pregnancy. Prenatal ultrasound revealed fetal ascites. At birth, the infant presented with severe respiratory failure requiring immediate resuscitation, endotracheal intubation, and intensive care support. Clinical findings included hepatosplenomegaly, generalized edema, ascites, petechial rash, palmoplantar desquamation, severe thrombocytopenia, anemia, coagulopathy, liver dysfunction, and hemorrhagic syndrome. Maternal and neonatal serologic testing confirmed syphilis infection. The clinical course was complicated by pneumonia with prolonged mechanical ventilation, cardiovascular involvement impairing cardiac function, and heart failure. Treatment consisted of intravenous penicillin G, broad-spectrum antimicrobial therapy, antifungal medication, respiratory support, transfusion therapy, cardiovascular management, and intensive multidisciplinary care; Conclusions: This report presents consequences of untreated maternal syphilis and underscores the importance of timely diagnosis, early initiation of penicillin therapy, and close multidisciplinary follow-up to optimize outcomes in neonates.
