Congenital syphilis unusually presenting with prematurity-related severe neonatal morbidities including meconium obstruction: A case report and review of the literature

RATIONALE: Congenital syphilis (CS) can manifest as a variety of clinical presentations according to the severity in symptomatic infants during neonatal period. Preterm neonates with CS may have more clinical evidences of infection and be more severely affected by CS compared with term ones. With increasing survival of markedly premature infants for recent decades, CS may be a challenging problem in those with severe manifestations associated with combined pathophysiologies of CS and prematurity. PATIENT CONCERNS: A very low birth weight infant at 32 weeks gestation presented with an unusual CS presentation consisting of prematurity-associated severe neonatal morbidities including meconium obstruction, prolonged cholestatic jaundice with elevated liver enzymes, and disseminated intravascular coagulation with a bleeding diathesis, in addition to common or typical manifestations of CS. DIAGNOSES: Congenital syphilis. INTERVENTIONS: Therapy consisting of a complete course of parenteral penicillin, blood component therapy, proximal ileotomy with inspissated meconium evacuation and distal loop ileostomy, and other conservative treatments. OUTCOMES: Resolution with normal gastrointestinal function and improved liver function was observed. LESSONS: This case suggests that in premature infants CS may manifest as unusual severe neonatal morbidities that may result from combination of syphilitic pathologies and contributors or conditions associated with prematurity including multisystem immaturity.
