A case of neonatal lupus erythematosus in a very low-birth-weight infant that suffered intraventricular hemorrhage at birth.

This report describes the case of a very low-birth-weight male infant with neonatal lupus erythematosus. His mother had Sjögren's syndrome, and her previous child had suffered a complete heart block. Accordingly, maternal steroid (betamethasone) therapy was administered to prevent a congenital heart block for 15 weeks (from 13 to 27 weeks' gestation). At 28 weeks' gestation, the mother was weaned off the steroid therapy, and an emergency cesarean section was carried out at 29 weeks and 6 days' gestation because of a nonreassuring fetal status (NRFS). At birth, the infant exhibited grade-III intraventricular hemorrhage (IVH). Although it is unclear why the infant developed a NRFS and IVH, the condition of the fetus should be carefully monitored during and after long-term maternal steroid treatment.

Liver fibrosis in an extremely small infant for gestational age.

Premature infants with intrauterine growth restriction (IUGR) are at greater risk for an adverse perinatal outcome. IUGR affects hepatocyte function, but the histopathological changes in the postnatal liver are not well known. We report a male infant with severe IUGR. His mother was transferred to our hospital at 26 weeks of gestation because of preterm labor and severe IUGR. An emergency cesarean section was carried out because of a non-reassuring fetal status. The birth weight of the infant was 332 g. He showed congestive heart failure and marked hepatomegaly from birth. After 1 week, blood examinations showed hyperbilirubinemia with high direct bilirubin. Because of liver dysfunction, he received the minimal total parenteral nutrition for 7 days. After 1 month, he progressively developed ascites and coagulopathy, and died 3 months after birth. Liver autopsy showed diffuse perisinusoidal fibrosis. Fibrosis was also prominent around the central vein. Immunohistochemical study revealed many alpha-smooth muscle actin-positive cells, which represent activated hepatic stellate cells, and a few transforming growth factor-beta1-positive cells in the perisinusoidal fibrotic area. These results indicate that the infant developed chronic (end stage) liver failure by 3 months of age. We excluded congenital infection, metabolic syndrome and citrin deficiency. It is therefore conceivable that intrauterine cardiac failure may be responsible for liver fibrosis. Early detection of liver dysfunction soon after birth is a key to predict the prognosis of severe IUGR in preterm infants.
