Group B Streptococcus (GBS) diagnosis

Understanding the Group B Streptococcus (GBS) diagnosis

by

Group B Streptococcus (GBS) Diagnosis  All pregnant women should be tested for GBS between 35 to 37 weeks of pregnancy. This involves taking swabs from the vagina and rectum to check for the presence of GBS. The test, known as a vaginal-rectal culture, looks for GBS bacteria growing in the samples. If results come back positive, it means the woman is colonized with GBS and is at higher risk of passing the infection to her newborn during delivery. Even if she tests negative during this screening, it’s still possible to acquire GBS later in pregnancy before delivery. That’s why women with risk factors such as a previous baby with GBS disease may be re-tested closer to their due date or during labor.

Signs and Symptoms of GBS Infection in Newborns

Newborns who develop GBS infection typically show signs within the first week of life, with most cases occurring within the first 6 days. Some potential signs of GBS infection in newborns include:

Fever – Rectal temperature of 100.4°F or higher
Breathing problems – Grunting, apnea (periods of stopped breathing), difficulty breathing
– Lethargy or irritability – The baby seems unusually tired, weak, or fussy
– Poor feeding – The baby is not interested in feeding or has difficulty feeding
Skin rash – Redness or blisters on the skin that don’t fade when gently pressed
Seizures – Uncontrolled muscle contractions or movements
– Trouble staying warm – The baby has a lower than normal body temperature

If a newborn exhibits any of these signs, it’s important to see a pediatrician right away for evaluation and testing, as prompt treatment is crucial for recovery from GBS infection. Left untreated, the infection can rapidly progress to sepsis and meningitis with severe complications.

Testing and Diagnosis of Early-Onset GBS Infection in Newborns

If a newborn is showing potential signs of GBS infection within the first week of life, the pediatrician will order several tests to help confirm or rule out the diagnosis. Two of the main tests used are:

– Blood culture – A small sample of blood is drawn from a vein and tested for the presence of GBS bacteria. This is considered the gold standard test.

– Cerebrospinal fluid (CSF) analysis – A sample of fluid surrounding the brain and spinal cord is collected via lumbar puncture (spinal tap) and analyzed microscopically and culturally for signs of bacterial infection and meningitis caused by GBS.

The pediatrician may also order additional tests like a complete blood count and C-reactive protein level to check for inflammation and other disorders. Chest x-rays may reveal signs of pneumonia if the infection has spread to the lungs. A positive blood or CSF culture confirms the diagnosis of early-onset GBS disease in newborns. Treatment with intravenous antibiotics is immediately started.

Risk Factors for Late-Onset GBS Infection

While early-onset GBS infection typically occurs within the first week of life, late-onset GBS infection can develop between 1 week to 3 months of age. Risk factors for late-onset GBS disease include:

– Preterm birth (less than 37 weeks gestation) – Premature infants have immature immune systems making them more vulnerable.
– Low birth weight – Babies under 2.5 kgs are at higher risk compared to normal and larger babies.
– Exposure to GBS during delivery – Even if adequately treated at birth, some infants may develop late-onset disease from GBS exposure during delivery.
– Being the second or subsequent born child – Older siblings of affected babies are also more likely to develop late-onset GBS disease.

The signs and symptoms of late-onset GBS infection are similar to early-onset disease. Treatment involves various tests like blood culture and lumbar puncture for Group B Streptococcus (GBS) diagnosis followed by intravenous antibiotics administered in the hospital. Long term sequelae are also possible in some cases. Therefore, following AAP guidelines for screening and prophylaxis during pregnancy helps reduce the overall risks.

Long-Term Complications of GBS Infection

While most infants recover fully from GBS disease with prompt treatment, some may face long-term health issues depending on the severity of the initial infection:

– Hearing loss –
Meningitis caused by GBS can damage the audio nerve leading to permanent hearing impairment. Regular follow-up audiology tests are needed.
Developmental delays – Issues like cerebral palsy, intellectual disabilities, and seizures may arise due to central nervous system involvement from severe GBS infection. Early intervention therapies can help.
– Lung disease – Pneumonia from GBS may potentially cause chronic lung issues including reactive airway disease in rare cases.
Strabismus – Crossed eyes can infrequently result due to inflammation and damage to cranial nerves during GBS meningitis. Sometimes surgery is required.

Hence, infants who have survived GBS disease require close long-term monitoring by pediatric specialists to screen for possible complications over time. With prompt identification and management, the outcomes can be improved significantly. Caregivers are also offered counseling and support.

GBS colonization during pregnancy raises the risks for early-onset newborn disease if not adequately treated during delivery. While antibiotics can help prevent transmission, the screening test may not detect all colonized women in late pregnancy. Newborns also remain at risk of late-onset GBS infection up to 3 months. Awareness of risk factors and prompt Group B Streptococcus (GBS) Diagnosis  are crucial for recovery. Long term consequences remain a possibility in severe infections despite treatment. Continued preventative efforts and interventions can further lower disease burden over time.
