Cerebrospinal fluid amino acid concentrations were measured in 16 pediatric patients with febrile convulsions, in 9 with bacterial meningitis, and in 8 noninfected newborn infants. Most CSF amino acids are present in greater concentration in patients with bacterial meningitis than in those without CNS infection. Newborn infants have elevated CNS amino acid concentrations similar to those found in older patients with bacterial meningitis. The reason for increased amino acid concentration in the meningitis group may be due to alterations in brain metabolism, changes in the kinetics of CSF formation, alterations in the removal of amino acids by active transport mechanisms, or a combination of factors. Delayed maturation of transport mechanisms may explain the high levels found in newborn infants.

Neurological disorders may be, specially in children, the first and dramatic troubles giving notice of the hematological disease. These disorders, listed according to their frequency are: cerebral vascular thrombosis, epilepsy, bacterial meningitis, meningism, cerebral thrombo-phlebitis, disorders of cranial nerves, hydrocephalus related to a pachy meningitis. One must be cautious with transfusions. Paraclinical neurological tests have no specificity.

The penetration of amoxicillin into cerebrospinal fluid (CFS) in the presence of meningeal inflammation was evaluated in patients with tuberculous meningitis. Serum and CSF concentrations of amoxicillin were measured at 2 h in nine patients who received a 1-g oral dose and at 1.5 and 4 h in ten patients who received a 2-g intravenous injection of sodium amoxicillin. After the oral dose, CSF concentrations ranged from 0.1 to 1.5 mug/ml. After the intravenous injection, CSF concentrations ranged from 2.9 to 40.0 mug/ml at 1.5 h and from 2.6 to 27.0 mug/ml at 4 h. These data on penetration suggest that parenterally administered sodium amoxicillin may be of value in the therapy of acute bacterial meningitis.

Non-invasive registration of systolic time intervals (STI) and ECG were used in evaluating cardiac function in 12 patients with bacterial and 16 with viral meningitis. On admission, 14 (50%) of the patients had abnormal STI. The preejection period (PEP) was prolonged in 11 patients, while left ventricular ejection time (LVET) was prolonged in two and shortened in four. The PEP/LVET index was increased in eight patients. At discharge PEP was still prolonged in eight patients; seven of these were from the viral meningitis group. LVET increased significantly (p less than 0.02) from the first to the last registration. In the patients with abnormal PEP and PEP/LVET on admission, there was a significant fall (p less than 0.05 and p = 0.02, respectively) to discharge. There was no difference in STI between the patients with viral or bacterial meningitis. Eighteen (64%) of the patients had abnormal STI on one or more registration. ST-T changes in ECG and prolongation of the Q-T interval were found in three patients. Cardiac affection in meningitis seems to occur more often than can be shown by ECG.

The Limulus lysate test was evaluated as a method for rapid detection of neonatal gram-negative bacterial meningitis. A total of 208 CSF samples were collected from 145 newborn infants suspected of having meningitis. Initial samples from all six babies with culture-proven gram-negative bacterial meningitis had positive Limulus tests within 30 minutes of incubation. Samples from 14 infants with gram-negative organisms isolated only in blood and/or urine as well as from four neonates with gram-positive organisms in CSF cultures and from 13 with gram-positive organisms in blood cultures all yielded negative Limulus tests. Thus, of 37 newborn infants with bacteria demonstrated in systemic cultures, only those six with gram-negative organisms in CSF had positive CSF Limulus tests. The CSF Limulus test was shown to be a rapid, reliable, and specific test for the detection on neonatal gram-negative bacterial meningitis.

Cerebrospinal fluid and serum immunoglobulins were studied in 76 patients with acute meningitis of various aetiologies. This comparative study showed that the increase of CSF immunoglobulin levels was related to important modifications of the permeability of the blood-brain barrier (especially in case of bacterial meningitis) or to a local in situ production (particularly in case of "viral" meningitis). Results obtained allow us to draw a different biochemical pattern in purulent meningitis and acute lymphocytic meningitis.

An analysis of 219 confirmed cases of bacterial meningitis among Navajo Indians during a 5-year period, July 1, 1968, through June 30, 1973, revealed that 56 percent were caused by Haemophilus influenzae, 26 percent by Neisseria meningitidis, 6 percent by Mycobacterium tuberculosis, and 6 percent by other organisms. The annual incidence of H. influenzae meningitis (17.7 per 100,000 persons) and that of pneumococcal meningitis (8.0 per 100,000) were much higher than the rates for these diseases reported from other population groups. The annual incidence of meningococcal meningitis (2.0 per 100,000) was similar to that found elsewhere. There was an ususual concentration of cases during the first year of life; 78 percent of H. influenzae, 64 percent of pneumococcal, and 50 percent of meningococcal meningitis occurred during this time. However, bacterial meningitis during the first month of life was not frequent (0.29 per 1,000 live births). Case fatality rates were similar to those reported for other population groups.

Bacterial meningitis should in principle be easily accessible to chemotherapy. The results of treatment cannot, however, be regarded at all optimistically although in recent years the therapy has brought an improvement in prognosis. Astonishingly, the therapeutic recommendations in common use even today are already 20 years old, so that the more favorable treatment results must be attributed to an earlier and more accurate diagnosis. The neurological damage following survival of meningitis is considerable, in particular, capacity to remember and powers of concentration remain impaired. Examination of these patients before school and observation during their schooldays is therefore essential.

Morbidity and mortality of suppurative bacterial meningitis show a very constant behavior over many decades. The introduction of antibiotics certainly lowered the lethality considerably, but since then it has remained fairly unchanged at about 15-20%. However, in the principal groups of pathogens--meningococci, pneumococci, Haemophilus influenzae--antibiotic resistence plays no special role. The significance of disorders of defense against infections for the course of the disease has not yet been investigated. Of 92 children examined with purulent meningitis, 49 showed a selective antibody deficiency syndrome against bacterial antigens, 38 of 48 children investigated showed further disorders of bactericidal activity. The proportion of these disorders is particularly high in children with defective healing of a meningitis.

Serum levels of 5 immunoglobulins (IgG, IgA, IgM, IgD and IgE) were determined at frequent intervals in the course of bacterial meningitis in children. 59 patients were examined; 27 with Haemophilus influenzae meningitis, 23 with meningococcal and 9 with pneumococcal meningitis. All 5 immunoglobulins increased during the 2-week course of bacterial meningitis. IgM was the immunoglobulin class responding most rapidly, regularly and intensively. IgG increased moderately. However, practically no rise of the IgG level was observed in children with H. influenzae meningitis. The elevation of the IgA and IgE levels possibly suggests that meningitis may also cause synthesis of IgA and IgE antibodies. The results of the study indicate that antibodies of all the 5 immunoglobulin classes are probably involved in the defense against the causative microbes in bacterial meningitis.
