Meningitis is the inflammation of the lining that covers the brain and spinal cord. It is usually caused by a bacterial or viral infection. Meningitis in the first month of life (neonatal meningitis) can be a devastating condition which may have neurological implications. The bacteria responsible for neonatal meningitis have remained the same over the past 20 years. These bacteria are Group B Streptococcus (GBS), Escherichia coli (E. coli), Listeria monocytogenes, and Streptococcus pneumonia.
How the baby gets neonatal meningitis depends on the bacteria responsible. GBS is usually transmitted to the baby from the mother’s genital or gastrointestinal tract around the time of birth. Listeria monocytogene is usually transmitted to the baby across the placenta before birth. Mothers with Listeria monocytogene infection generally have a ‘flu-like’ illness in the week, or so, before the baby is delivered.
However, this ‘flu-like’ illness is often not severe enough for recognition that the mother has the infection. It is during this flu-like illness that the bacteria can cross the placenta to infect the baby. These babies who are infected are unwell as soon as they are born. In addition, the infection in the baby may result in premature birth.
Symptoms of meningitis in babies include:
- excessive crying (often different to their usual cry)
- fast or unusual breathing patterns
- fever with cold hands or feet
- not taking feeds or repeated vomiting
- being irritable, especially when handled
To diagnose the condition and the bacteria responsible, a lumbar puncture will be carried out. Treatment involves a range of antibiotics.
Pneumonia is a condition where the lungs are inflamed. It is usually caused by a bacterial or viral infection. If the onset of pneumonia occurs within hours of birth, the condition may be part of a generalised sepsis syndrome. However, if the onset of pneumonia is after 7 days, it’s likely confined to the lungs.
The risk of a baby developing pneumonia is increased in cases where the mother had:
- an unexpected high temperature in labour
- prolonged rupture of membranes
- a meconium-stained or foul smelling liquor/amniotic fluid
- a history of recurrent genitourinary infection in pregnancy.
In the neonatal unit, it commonly occurs amongst babies who require or have had, prolonged endotracheal intubation because of lung disease.
In spite of radiological imaging, pneumonia can be difficult to diagnose in newborn babies because secretions may be difficult to obtain from them. Signs of pneumonia may be limited to respiratory distress, but may also include the following:
- a high temperature, typically over 102 °F
- lack of energy
- laboured breathing
Breathing patterns may be either rapid, but shallow, or from the stomach instead of the chest. These breathing patterns may also be along with excessive nose flaring or wheezing. There is the possibility that your baby will need some help breathing through mechanical ventilation. Your baby may be unable, or too breathless, to feed from the breast or bottle and may require some tube feeds until they are well again.
Diagnosis is made by X-ray, and a clinical and laboratory evaluation if testing for a generalised sepsis syndrome. Treatment is initially with broad-spectrum antibiotics which are changed to organism-specific antibiotics as soon as possible following laboratory results/culture reports. To fight the infection, antibiotics are given through an intravenous line or cannula.
