Five infants with pneumococcal sepsis presented with respiratory distress and clinical signs of infection in the first day of life. Although there was no apparent epidemiological relationship among the patients, four of the five were seen within a 12-month period. Pneumonia, prolonged rupture of fetal membranes, and prematurity were features in these patients. Three infants died, two within 12 hours of diagnosis. Streptococcus pneumoniae was isolated from the vagina of three of the mothers; in two, the serotype was identical to that recovered from their infants. Clinical features of neonatal pneumococcal sepsis are similar to those of early-onset group B streptococcal infection. Like the group B Streptococcus, S. pneumoniae acquired from the maternal vagina is a potential life-threatening pathogen in the newborn period.

In a retrospective analysis of infants born with meconium staining over an 18-month period at Cook County Hospital, 32 infants met two of the three criteria for the diagnosis of meconium aspiration syndrome: (1) history of meconium in the oropharynx or trachea; (2) clinical evidence of respiratory distress; and (3) x-ray evidence of aspiration pneumonia. Seventeen infants developed respiratory failure; nine of these infants died. One infant without respiratory failure died of sepsis. Analysis of sequential arterial blood pH and gas tension showed that nonsurviving infants had persistently high PCO2 and A-a gradient in spite of initiation of assisted ventilation. These changes seem to be related to severe right-to-left shunting and ventilation perfusion abnormalities. The data further suggest that asphyxia and acidosis occur well before the infant is born and that intrapartum monitoring to recognize fetal asphyxia may help in improving morbidity and mortality from meconium aspiration syndrome.

Chest roentgenograms obtained in the first two days of life from 67 infants with respiratory distress were reviewed to determine whether the radiographic features of group B streptococcal septicemia were diagnostic or distinctive. The retrospective review contained 24 infants with proven and 14 with suspected septicemia, as well as 29 patients with other causes of respiratory distress. The films were reviewed in random order by two pediatric radiologists without their prior knowledge of clinical or laboratory data. Typical radiographic appearance of pneumonia was present in only ten of the 24 proven and two of the 14 suspected cases of group B streptococcal sepsis. The radiographic pattern of respiratory distress syndrome (RDS) was just as common among these patients. The most prominent associated radiographic feature of infants with proven septicemia was cardiomegaly which was significantly increased when compared with infants who had other causes of respiratory distress (P less than .001). X-ray recognition of neonatal group B streptococcal septicemia is limited because of superimposition of roentgen patterns probably related to associated disorders.

Newborn infants with "early-onset" disease due to group B beta hemolytic streptococcus were studied over a 40-month period. Clinical presentations included asymptomatic bacteremia, mild transient illness, respiratory distress, meningitis, and overwhelming sepsis. Chronologically, 18 were ill at birth; 10 became ill after a symptom-free period; and four were asymptomatic. Sixty-six percent of the cases weighted less than 2500 grams, and 56% were born to mothers whose amniotic membranes were ruptured for over 20 hours. All 15 of the deaths occurred in low birth weight infants who were criticially ill from birth. A review of 128 consecutive deliveries of infants weighing under 2000 grams revealed 28 cases with prolonged ruptured membranes, and three of these 28 infants developed group B streptococcal infection. The infant of the colonized gravid woman in premature labor or with prolonged ruptured membranes is clearly at risk, and these results suggest that the management of "early-onset" disease should begin prior to delivery.

The newborn infant, particularly when premature, has a haemostatic mechanism which may not be entirely capable of withstanding the onslaughts of trauma, infection, asphyxia or other complications of the neonatal period. He is at risk of local or diffuse haemorrhage, which may at times be serious or even life-threatening. The cause of haemorrhage during the newborn period can generally be ascertained by a careful history and brief physical examination directed toward recognition of any predisposing factors or underlying diseases. Screening laboratory tests can usually be correctly interpreted as long as certain laboratory artifacts and physiological peculiarities of the neonatal coagulation mechanism are kept in mind. Diagnosis of and therapy for vitamin K deficiency and haemophilia in the healthy-appearing neonate is generally carried out with little difficulty. The seriously ill neonate with bacterial sepsis, respiratory distress syndrome, or extreme immaturity presents greater problems, for laboratory tests may be more difficult to obtain and interpret and underlying conditions may be untreatable. DIC occurs commonly in such neonates, and transfusion therapy, with or without heparin, is often unsuccessful. A persistent dilemma are those neonates with fatal intravascular haemorrhage, in whom definable haemostatic abnormalities are few and transfusion therapy is futile.

The clinical features of 27 patients with early onset group B beta hemolytic streptococcus sepsis were reviewed. Fifteen presented with a clinical pattern indistinguishable from the idiopathic respiratory distress syndrome and were compared with 15 patients with IRDS. Rupture of membranes for greater than 12 hours prior to delivery occurred more often in patients with GBS (33%) than in the patients with IRDS (16%). Hypotension was more commonly seen in the patients with GBS (56%) than in the patients with IRDS (36%). There was no difference in the incidence of apnea or the respirator peak inspiratory pressure requirements between the two groups of patients, but there was a tendency for a decline in the total white blood cell count in the first 24 hours of life in those patients with GBS sepsis.

Immunofluorescence was performed on lung tissue obtained at necropsy from 18 newborn infants, including five with group B streptococcal (GBS) sepsis, seven with idiopathic respiratory distress syndrome (IRDS), and six control infants who died from other causes. Deposits of C3, IgG, and fibrin were found within hyaline membranes of infants who died with GBS sepsis or IRDS within 48 hours after birth. In some cases C4, factor B, and IgM were also observed. In five infants with IRDS who died more than five days after birth, immunofluorescent lung findings were less common and less intense. Hyaline membranes, attributed to mechanical ventilators and oxygen therapy in two infants who did not have GBS infection or IRDS, were negative for complement and immunoglobulins although fibrin was detected in one specimen. These data suggest that immunologic processes may contribute to the pathogenesis of certain types of acute lung injury, particularly in infants who die from GBS infection or IRDS during the early neonatal period.

A full-term infant became ill at 16--24 h of age following an uncomplicated pregnancy, labor, and delivery. The clinical course (absence of prenatal warning, rapidly progressive respiratory distress, apnea, shock, and coagulopathy) terminated fatally and resembled that seen in neonatal 'early onset' group B streptococcal sepsis. Previous cases of neonatal group G streptococcal disease are briefly reviewed.

The purpose of this study was to assess the usefulness of the white cell ratio of immature neutrophils (PMNs) to total (immature plus mature) PMNs as an indication of infection in the very small premature infant. We retrospectively reviewed the charts of 59 premature infants less than or equal to 1,250 g admitted to our Newborn Intensive Care Unit over a one-year period who had at least one white count determined. Twenty-three were born after rupture of membranes for greater than or equal to 24 hours (PROM), 47 had a one-minute Apgar score less than or equal to 6 and 31 had a five-minute Apgar scores less than or equal to 6, 38 had respiratory distress syndrome (RDS), and 4 had confirmed infection. Thirty-one of the infants had a ratio greater than or equal to .15 in the first day of life, a value which has been suggested in the literature as being abnormal and an indication to suspect sepsis. This ratio bore no statistical relationship to PROM, low Apgar scores, or RDS. We analyzed these same relationships using a ratio greater than or equal to .25, another ratio derived from data in the literature which has been said to suggest infection. No statistical correlation was found for low Apgars or RDS, but there was a significant relationship between PROM and attainment of a ratio greater than or equal to .25 (p less than .005). It is notable that 2 out of the 4 infants with infection had a ratio less than .15. We wish to cast doubt on the applicability of the currently defined WBC ratios in the literature as they apply to the infant with birth weight less than 1,250 g and emphasize the apparent effect of PROM as a factor upon these ratios.

Respiratory distress is the most frequent symptom initiating referral to neonatal intensive care centers. Previous reports have indicated that 40% of infants with sepsis proved by blood culture had respiratory symptoms as their clinical presentation. In this prospective study there were 145 consecutive infants referred because of respiratory distress. Two-site blood cultures were collated with all other clinical and laboratory data to confirm a diagnosis of septicemia. There was a 4.8% incidence of bacteremia, and clinical and laboratory parameters confirmed septicemia in 3.5% of infants studied. Sixty percent of these infants had group B streptococcal sepsis, and 80% had leukopenia. The low incidence of confirmed septicemia in infants referred because of respiratory distress suggests that antibiotic therapy should not be routine.
