Although the occurrence of neonatal meningitis is uncommon , it remains a devastating infection with high mortality and high morbidity . Neonatal meningitis is often caused by group B streptococcus Despite the development of effective vaccines, useful tools for rapid identification of pathogens and potent antimicrobial drugs, neonatal meningitis continues to contribute to neurological disability worldwide
The persistence of neonatal meningitis results from increases in the numbers of infants surviving premature delivery. In addition, the absence of specific clinical findings makes diagnosis of meningitis more difficult in neonates than in older children and adults. Moreover, a wide variety of pathogens are seen in infants as a consequence of the immaturity of their immune systems and intimate exposure to possible infection from their mothers .
Etiology Common bacterial pathogens group B streptococci (GBS ) are the most commonly identified causes of bacterial meningitis, implicated in roughly 50% of all cases [ 5 ] . Escherichia coli accounts for another 20% [ 6 ] . Listeria monocytogenes is the third most common pathogen, accounting for 5–10% of cases ; [ 6 ] . Studies suggest that in underdeveloped countries , gram-negative bacilli—specifically, Klebsiella organisms and E coli —may be more common than GBS [ 7 ]
Epidemiology The incidence of neonatal meningitis is estimated to be 0.3 per 1000 live births, as observed in the United States , Sweden, The Netherlands, England, and Wales. [4 Reported estimated incidences of neonatal meningitis that ranged from 0.48 per 1000 live births in Hong Kong to 2.4 per 1000 live births in Kuwait . [7]
Neonatal Meningitis Clinical Presentation Signs and symptoms of neonatal meningitis are often subtle , making diagnosis difficult that leads to morbidity. Clinical signs of the infection are including but not limited to: Fever or hypothermia Irritability or lethargy Hypotonia Feeding intolerance or vomiting Respiratory distress Apnea Bradycardia Hypotension Poor perfusion Seizures Bulging anterior fontanel Nuchal rigidity Jaundice Hypo- or hyperglycemia Diarrhea
Detection of neonatal meningitis is often late , with signs such as nuchal rigidity, bulging anterior fontanel, and convulsions . These symptoms are a predictor for a poor prognosis for the infant . In evaluating a neonate for meningitis, the following 3 key points should be kept in mind: It is important to remain vigilant for maternal infection “setups” ( eg , prolonged rupture of membranes, fever, and chorioamnionitis) while remembering that asymptomatic maternal infection is always a possibility even with screening Early-onset and late-onset bacterial infections have distinctive clinical courses (see below) In herpes simplex virus (HSV) infections, the presence of skin lesions in a meningitic neonate is the exception rather than the rule cluding severe neurological impairments.
Brudzinski sign (hip & knee flexion with neck movement) Kernig sign (extend knee with hip flexed) The sensitivity and negative predictive value o f Kernig and Brudzinski sign is low in the diagnosis of meningitis and therefore do not contribute to the diagnosis of bacterial meningitis
Case definition : suspected case: fever of 38 or more plus one or more of the following: 1- neck stiffness 2– bulging fontanel in children below 2 years
Probable case: suspected case with turbidity of C.S.F which means: cells ↑ 80 / m3 protein ↑100 /dl sugar ↓ 40 / dL plus one or more of the following: 1- Gm staing show : - ve : N. meningiococcal (+ Epedmic ) - H.infulnza b + ve : pneumocci 2- antibodies in C .S .F by( latex antigen detection )
Confirmed case : confirmed by lab. : 1- C.S. F culture 2- P.C.R
Bacterial meningitis Early onset in the first 48 hours of life temperature instability, episodes of apnea or bradycardia, hypotension, feeding difficulty, hepatic dysfunction, and irritability alternating with lethargy. [1] Respiratory symptoms can become prominent within hours of birth in group B streptococcal (GBS ) infection; however, the symptom complex also is seen with infection by E coli or Listeria species.
Late-onset bacterial meningitis onset after 48 hours of life) associated with neurological symptoms . stupor and irritability, more than 75 % of affected neonates. Between 25% and 50% of neonates will exhibit the following neurological signs: Seizures Bulging anterior fontanel Extensor posturing or opisthotonos Focal cerebral signs including gaze deviation and hemiparesis Cranial nerve palsies Nuchal rigidity is the least common sign in neonatal bacterial meningitis, occurring in fewer than 25% of affected neonates. [ 1
HSV meningitis Early features of HSV meningitis may mimic with bacterial meningitis, including pallor, irritability, high-pitched cry, respiratory distress, fever, or jaundice, progressing to pneumonitis, seizures, hepatic dysfunction, and disseminated intravascular coagulopathy (DIC). [16]
Complications cerebral edema, hydrocephalus , hemorrhage , ventriculitis (especially with bacterial infection), abscess formation, and cerebral infarction . Cerebral edema , hydrocephalus, and hemorrhage each may cause increased intracranial pressure, with potential for secondary ischemic injury to the brain because of decreased brain perfusion : Cerebral edema results from vasogenic changes, cytotoxic cell injury , and, at times, inappropriate antidiuretic hormone (ADH) secretion Hydrocephalus results from debris obstructing the flow of cerebrospinal fluid (CSF) through the ventricular system or from dysfunction of arachnoid villi; it occurs in as many as 24% of neonates with bacterial meningitis [22] Hemorrhage occurs in regions of infarction or necrosis and should be suspected in a neonate with new focal neurological findings or clinical deterioration
Ventriculitis results in sequestration of infection to areas that are poorly accessible to systemic antimicrobial drugs . Inflammation of the ependymal lining of ventricles often obstructs CSF flow. Thus, all of these complications are interactive, making effective management difficult. Ventriculitis occurs in as many as 20% of infected neonates . [23] Failure to respond to appropriate antibiotic therapy and signs of elevated intracranial pressure (ICP) may suggest the diagnosis. [24] Intraventricular administration of antibiotics may be necessary in cases of ventriculitis.
Cerebral abscess occurs in as many as 13% of neonates with meningitis. [22] New seizures, signs of elevated ICP , or new focal neurological signs suggest the diagnosis. Brain imaging with contrast is essential for making the definitive diagnosis. Surgical intervention may be required.
Cerebral abscess occurs in as many as 13% of neonates with meningitis. [22] New seizures, signs of elevated ICP , or new focal neurological signs suggest the diagnosis. Brain imaging with contrast is essential for making the definitive diagnosis. Surgical intervention may be required.
Cerebral infarction , both focal (arterial) and diffuse (venous), may complicate recovery. Autopsy studies have found evidence of infarction in 30-50% of specimens studied. [1] Imaging studies suggest that the actual incidence of infarction may be even higher. [25] Meningitis has been shown to be associated with 1.6% of all cases of neonatal arterial stroke and 7.7% of venous infarcts . [26] Necrotizing lesions secondary to HSV meningitis can be deleterious to the developing brain.
longer-term complications that may develop include residual epilepsy , cognitive impairment , hearing loss , visual impairment, spastic paresis , and microcephaly. Some of these disorders may be difficult to detect during infancy. Hearing , for example, is difficult to evaluate without the child’s cooperation, and even then, assessment may be limited to behavioral response to sounds. Brainstem auditory evoked response (BAER) testing does not evaluate all dimensions of hearing, but this test, which can be performed reliably in sedated infants, only slightly overestimates hearing loss, which occurs in 30% of survivors of bacterial meningitis and 14% of survivors of nonbacterial meningitis. [27] Subtle impairment of sound discrimination may not be readily apparent.
Long-Term Monitoring Because of the potential for hearing loss, neonates with meningitis should undergo brainstem auditory evoked response (BAER) testing at 4-6 weeks after discharge. [40] Survivors of neonatal meningitis require long-term surveillance not only for disorders of hearing but also for disorders of vision, motor, or cognitive function. Developmental delay is a frequent complication of neonatal meningitis. Early intervention services should be employed to maximize developmental gains
cognitive impairment may not be evident until the child has started school or advanced into higher grades where more complex analysis of information is necessary. [20] Careful screening for neurological, cognitive, and developmental deficits must be conducted as part of routine pediatric care over a period of many years , and the responsible physician should be attentive to possible problems with perception, learning, or behavior that may result from neonatal infection.
Laboratory Studies Lumbar Puncture Lumbar puncture is indicated for evaluation of the CSF in all neonates suspected of having sepsis or meningitis, even in the absence of neurological signs. Many clinicians are reluctant to perform this procedure on a critically ill infant. Although the theoretical complications of lumbar puncture include trauma, brain-stem herniation, introduction of infection, and hypoxic stress, none of these complications were reported in a meta-analysis of more than 10,000 infants who underwent lumbar puncture. [29] .
Meningitis, however, increases the risk of death in neonates. Stoll et al reported a mortality of 23% in babies with CSF-proven meningitis, compared with a mortality of 9% in neonates whose lumbar puncture results were not consistent with meningitis. [35] Additionally, many infants who had negative blood cultures had positive CSF cultures , suggesting that cases of meningitis may be missed. In cases of bacterial meningitis, repeat lumbar puncture should be performed 24-48 hours after initiation of therapy to ensure sterilization of the CSF. After a full course of therapy for PCR-proven HSV, repeat lumbar puncture should be undertaken to rule out incompletely treated infections
It should be kept in mind that interpretation of CSF findings is more difficult in neonates than in older children , especially in premature infants whose more permeable blood-brain barrier causes higher levels of glucose and protein. The number of white blood cells (WBCs ) found in the CSF in healthy neonates varies according to gestational age .1 The classic finding of decreased CSF glucose , elevated CSF protein, and pleocytosis is seen more with gram-negative meningitis and with late gram-positive meningitis ; this combination also is suggestive of viral meningitis, especially HSV.
Many authors use a cutoff value of 20-30/µL . Bacterial meningitis commonly causes CSF pleocytosis greater than 100/µL, with predominantly polymorphonuclear leukocytes (PMNs) gradually evolving to lymphocytes. In neonates with viral meningitis , the picture may be similar but with a less dramatic pleocytosis. HSV meningitis may be particularly associated with a large number of red blood cells (RBCs) in the CSF . If the mother is symptomatic, maternal investigation may be warranted; bacterial or viral cultures can provide valuable adjunctive information.
Polymerase chain reaction (PCR) assay is a powerful diagnostic tool with excellent sensitivity and specificity . It permits identification of group B streptococcal ( GBS) antigen in urine or CSF , and it is the standard for identification of herpes simplex virus (HSV) and enterovirus in CSF . In neonates, PCR is 71-100% sensitive for HSV but 98-99% specific. [16
Magnetic Resonance Imaging Magnetic resonance imaging (MRI) is the neuroimaging modality of choice for identifying focal areas of infection, infarction , secondary hemorrhage, cerebral edema, hydrocephalus, or, rarely, abscess formation. Sinovenous occlusions, ventriculitis, and subdural collections are best diagnosed with MRI. Follow-up MRI scans are useful for following the resolution of the infection, as well as for contributing to prognostication. If available, magnetic resonance spectroscopy can add important information on the metabolic function of the neonatal brain. Several studies have documented periventricular white matter abnormalities on MRI in infants with neonatal meningitis. [31] Newer MRI technologies, including diffusion-weighted and diffusion tensor imaging, have allowed this association to be evaluated in more detail, and such evaluation may prove to have prognostic implications. [ 32 ]
MR Angiography (MRA) In magnetic resonance angiography (MRA), a powerful magnetic field, radio frequency waves and a computer are used to evaluate blood vessels and help identify abnormalities1 Magnetic Resonance Venography (MRV) An MRV uses magnetic resonance technology and intravenous (IV) contrast dye to visualize the veins . Contrast dye causes the blood vessels to appear opaque on the X-ray image, allowing the physician to visualize the blood vessels being evaluated.
Other Imaging Modalities (CT ) carries the risk of exposing the neonatal brain to radiation, the rapidity and ease with which it can be obtained (in comparison with MRI) makes it useful in decision-making for potential neurosurgical interventions, such as ventriculostomy for hydrocephalus or surgical drainage of empyema or abscess . It may be particularly appropriate for a critically ill neonate being considered for neurosurgery. Cranial ultrasonography provides an alternative imaging modality for critically ill neonates , but it does not provide optimal detail in all circumstances. However, it is a low-risk and thus is useful in monitoring ventricular size for hydrocephalus during the acute phase of meningitis. Chest radiography provides important information about the lung parenchyma and the cardiac silhouette. Meningitis or sepsis may occur with pneumonia but may be indistinguishable from surfactant deficiency, pulmonary hypertension, and obstructive cardiac disease.
Electroencephalography (EEG) is not an essential part of the initial diagnostic process. However, in neonates who are unresponsive or have seizures presenting as episodes of apnea, bradycardia, or rhythmic focal movements, EEG monitoring provides useful information to guide treatment with anticonvulsant drugs. EEG also has some prognostic utility
Neonatal Meningitis Treatment & Management early initiation of antimicrobial drugs is essential Aggressive antimicrobial intervention is lifesaving in neonates with suspected meningitis. \Because distinguishing viral from bacterial meningitis is difficult early in the clinical course, a combination of agents is often necessary, providing coverage for both types of infection. The duration of therapy for bacterial and herpes simplex virus (HSV) meningitis with an appropriate agent is typically 14-21 days Although there is a consensus that acyclovir is the preferred antiviral therapy, there remains some disagreement with respect to what constitutes optimal antibacterial therapy.
The choice of an antibiotic regimen should be based on the likely pathogen , the local patterns of antibacterial drug sensitivities , and the policies of the hospital. Corticosteroids have been shown to reduce long-term sequelae, particularly hearing loss, in older infants with Haemophilus influenzae type B meningitis and S pneumoniae infection. However, use of corticosteroids is not recommended for neonates with meningitis management of seizures is a common challenge in neonates with meningitis. Phenobarbital and phenytoin remain the current drugs of choice, with benzodiazepines utilized as adjunctive therapy
Assessment of response to therapy Lumbar puncture , should be repeated 24-48 hours after the initial study to monitor the course of the infection and guide further treatment decisions. If the patient has persistent infection in the lumbar CSF or clinical deterioration that is not explained by other complications, imaging studies to investigate for abscess formation should be performed. A diagnostic tap of the lateral ventricle should be considered to assess for ventriculitis if no focal abscess is noted on imaging. Ventriculitis may occur, especially with gram-negative bacteria , in the absence of pleocytosis in the lumbar CSF or with sterile CSF.
infants with partially treated bacterial meningitis should be managed on a case-by-case basis in accordance with their clinical presentation . These infants should be observed for at least 48 hours after treatment is discontinued. C-reactive protein levels can be useful in identifying the presence of a systemic anti-inflammatory response and can be used serially to track the response to treatment.
Ventriculostomy Ventriculostomy with external drainage may be required in cases where acute hydrocephalus develops secondary to obstruction of CSF flow. Administration of intraventricular antibiotics is recommended in cases of ventriculitis, but is no longer recommended as a routine treatment for gram-negative meningitis
Prognosis 25-50% have significant problems with language, motor function, hearing, vision, and cognition [18, 3] ; 5-20% have future epilepsy . [19, 20] Survivors are also more likely to have subtle problems, including visual deficits, middle-ear disease, and behavioral problems. [21] As many as 20% of children identified as normal at 5-year follow-up may have significant educational difficulties lasting into late adolescence. [18]

Prevention The use of intrapartum antibiotic prophylaxis in pregnant mothers who are positive for group B streptococcal (GBS) colonization on screening or have risk factors for GBS colonization has reduced the incidence of neonatal early-onset GBS meningitis from approximately 1.8 cases to 0.3 cases per 1000 live births. [9] Screening and risk factor assessment should be included universally in routine prenatal care. Cesarean delivery decreases , but does not eliminate, transmission of HSV from the mother’s genital tract to the neonate in cases of known infection. Suppressive antiviral therapy for HSV-infected women during the third trimester may prevent recurrent infectious episodes and thereby minimize the infant’s exposure to the virus during delivery. [16]
Diet Listeria monocytogenes and Escherichia coli are bacteria found in contaminated foods that can cause neonatal meningitis. [43] By avoiding certain foods and safely preparing produce, pregnant mothers can reduce the risk of neonatal meningitis caused by these bacteria. Foods to avoid that may be contaminated by listeria include: Soft cheeses made with unpasteurized milk Smoked seafood that is not canned or shelf-stable Raw ( unpasteurized) milk Foods that must be safely prepared to prevent the growth of listeria and E. coli include: Raw sprouts Melons الشمام Hot dogs, deli meat, and cold cuts اللحوم الباردة

Vaccinations for Meningitis
The five most common types (or serogroups ) of meningococcal bacteria found are A, B, C, W and Y. No single vaccine protects against all serogroups ; there are separate vaccines against meningococcal ACWY serogroups and the meniningococcal B serogroup
A smaller yet steady rise in the occurrence of meningococcal Y disease has also been seen since 2016. Together, meningococcal W and Y disease cause approximately half of the cases of IMD in Australia. Meningococcal B , which historically caused the majority of meningococcal disease in Australia , continues to cause around half of all reported cases of IMD
