Overview

Group B streptococcal septicemia is a severe bacterial infection that affects newborn infants.

What are the symptoms of Group B streptococcal septicemia of the newborn?

  • Anxious or stressed appearance
  • Blue appearance (cyanosis)
  • Breathing difficulties such as:
  • Grunting noises
  • Flaring of the nostrils
  • Rapid breathing
  • Short periods without breathing
  • Irregular heart rate - may be fast or extremely slow
  • Lethargy
  • Pale appearance (pallor) with cold skin
  • Poor feeding
  • Unstable body temperature (low or high)

What causes Group B streptococcal septicemia of the newborn?

  • The term septicemia refers to an infection in the bloodstream that may travel to different body organs. Group B streptococcal septicemia is caused by the bacterium Streptococcus agalactiae, which is commonly called "group B strep" or GBS. A newborn with septicemia is very sick.
  • GBS is commonly found in adults and older children, where it does not usually cause infection. There are two ways in which it may be passed to a newborn baby:
  • The infant can become infected as he or she passes through the birth canal. In this case, babies become ill between birth and 6 days of life (most often in the first 24 hours). This is called early-onset GBS disease.
  • The infant may also become infected after delivery by coming into contact with people who carry the GBS germ. In this case symptoms appear later, when the baby is 7 days to 3 months or more old. This is called late-onset GBS disease.
  • GBS now occurs less often, because methods to screen and treat pregnant women at risk are now being used.
  • The following increase an infant's risk for group B streptococcal septicemia:
  • History of giving birth to a baby with GBS sepsis
  • Mother who has a fever (over 100.4 degrees F) during labor
  • Mother who has group B streptococcus in her gastrointestinal, reproductive, or urinary tract
  • Prematurity
  • Rupture of membranes ("water breaks") more than 18 hours before baby is delivered
  • Use of intrauterine fetal monitoring (scalp lead) during labor

When to seek urgent medical care?

  • This disease is usually diagnosed shortly after birth, often while the baby is still in the hospital.
  • However, if you have a newborn at home who shows symptoms of this condition, seek immediate emergency medical help or call the local emergency number (such as 911).
  • Parents should particularly watch for symptoms in their baby's first 6 weeks. The early stages of this disease can produce subtle symptoms.

Diagnosis

  • To diagnose GBS septicemia, GBS bacteria must be found in a sample of blood (blood culture) taken from a sick newborn.
  • Other tests that may be done include:

Treatment options

  • Treatment may involve one or more of the following:
  • Antibiotics given through a vein
  • Breathing help (respiratory support)
  • Fluids given through a vein
  • Medicines to reverse shock
  • Medicines or procedures to correct blood clotting problems
  • Oxygen therapy
  • A complex therapy called extra-corporeal membrane oxygenation (ECMO) may be used in very severe cases.

What to expect (Outlook/Prognosis)?

This disease can be deadly without prompt treatment.

Possible complications

  • Disseminated intravascular coagulation (DIC) - a serious disorder in which the proteins that control blood clotting are abnormally active
  • Hypoglycemia - low blood sugar
  • Meningitis - swelling (inflammation) of the membranes covering the brain and spinal cord caused by infection
  • Respiratory failure - breathing stops

Prevention

  • The American Academy of Pediatrics, American College of Obstetricians and Gynecologists, and U.S. Centers for Disease Control and Prevention have established two methods to help reduce the risk of Group B streptococcal septicemia:
  • Pregnant women are tested for group B streptococcus at 35 - 37 weeks into their pregnancy. If the bacteria are detected, women are given antibiotics through a vein during labor.
  • Prenatal screening is not done, but a woman who meets certain risk factors is given antibiotics through a vein during labor.
  • Both sets of procedures are currently accepted as the standard of care.
  • Newborns who are at high risk are tested for GBS infection. They may receive antibiotics through a vein during the first 48 hours of life until blood culture results are available.
  • In all cases, proper hand washing by nursery caretakers, visitors, and parents helps prevent the spread of the bacteria after the infant is born.
  • An early diagnosis can help decrease the risk of some complications.
