Fatal ureaplasma infection in second twin born 60 days after delivery of the first in a patient with recurrent spontaneous abortion--a case report.

A delay of more than one month between the birth of twins is an unusual occurrence presenting the obstetrician and the neonatalogist with many questions regarding the management of the case. There is the risk of prematurity for the second twin as labor has already occurred in the pregnancy. There is also a risk of infection to both mother and fetus during the interval between the two deliveries, since the stump of the first twin's cord may precipitate ascending colonization from vagina and cervix. Germs frequently recovered from the vagina e.g. Ureaplasma urealyticum, are associated with prematurity. The latter has also been responsible for lethal interstitial pneumonia in the neonate. We present a case of a patient who though she delivered twice normally, had suffered 4 first trimester abortions and one late abortion, all spontaneous. Her eighth pregnancy was a twin pregnancy. She underwent a cerclage at 14 weeks, but went into labor at 17 weeks, when she delivered the first macerated twin. She was then treated with fenoterol and ampicillin; nevertheless she delivered twin the second at 26 weeks. This 750 g baby-girl presented with severe respiratory distress. Repeated chest X rays showed perihilar infiltrates which became nodular. All cultures were negative. At the end of the first week, when her condition was considered satisfactory, she deteriorated dramatically and died in respiratory failure and DIC. Tracheal aspirates were positive for Ureaplasma urealyticum.

Maternal and infant sexually transmitted diseases.

Sexually transmitted infection may result in serious damage to the reproductive tract of the mother, damage to the fetus, wastage of pregnancy, or illness or death of the infant. The effects of gonorrhea, Chlamydia trachomatis infection, mycoplasmal infections, group B streptococcus infections, syphilis, and viral infections are discussed separately for both mother and infant.

Serological evidence of Ureaplasma urealyticum infection in neonatal respiratory disease.

Since up to 80 percent of pregnant women and 30 percent of neonates may be colonized with genital mycoplasmas, it is difficult to determine whether true infection occurs. The antibody responses to eight serotypes of U. urealyticum were assessed in mothers and infants in 21 cases of neonatal respiratory disease (RD) and 24 normal cases. Among the normal population of mothers and infants, a titer of greater than or equal to 1:32 occurred in 0.25 percent (1/394). In mother-infant paired titers, a fourfold difference occurred in 2.6 percent (5/192). Among 54 RD neonates, 55.6 percent had a titer of greater than or equal to 1:32 compared to only 4.2 percent of normal neonates (p less than .001). Fourfold elevations in antibody titers of greater than 1:32 were observed in the neonate in 52.4 percent of RD cases compared to 0 percent of 24 normal pairs (p less than .001) and in 28.6 percent of mothers of RD neonates compared to 0 percent in normal cases (p = .013). We observed that 43.3 percent of RD neonates with titers greater than or equal to 1:32 died compared to 16.6 percent of RD neonates exhibiting no elevation of antibody response over the maternal level. Among the six who died, 66.7 percent of neonates and 16.7 percent of their mothers had elevated titers, compared to 33.3 percent of 15 surviving infants and 40.0 percent of their mothers. These elevated antibody responses strongly support the concept that U. urealyticum causes infection in the perinatal period in association with neonatal respiratory disease. Since the elevation in titers was detected close to delivery in many cases, the infection may occur in utero.
