Lysozyme is absent from normal cerebrospinal fluid (C.S.F.) and in C.S.F. from children with viral meningitis. Appreciable amounts of lysozyme were noted in C.S.F. from children with bacterial meningitis (0.23 +/- 0.14 mg/100 ml) and cerebral convulsions (0-0.82 mg/100 ml). The C.S.F.-lysozyme content is a sensitive indicator for bacterial meningitis and important in the differential diagnosis between viral and bacterial meningitis. The beta2-microglobulin content of C.S.F. in healthy children was 0.11 +/- 0.05 mg/100 ml; in children with viral meningitis 0.20 +/- 0.06 mg/100 ml and in children with bacterial meningitis 0.44 +/- 0.17 mg/100 ml. Children with cerebral convulsions had also a rise in C.S.F. beta2-microglobulin.

Cerebrospinal fluid (CSF) immunoglobulins were measured in 62 normal children, in 9 children with purulent meningitis, and in 10 children with presumptive viral meningitis. The mean values in normal children were IgA 0, IgM 0, and IgG 0.84 +/- 1.4 mg/100 ml (+/- SD). The mean levels of all CSF immunoglobulins were raised in acute bacterial meningitis and were significantly greater than the levels found in viral meningitis. CSF IgM was 0.16 +/- 0.5 mg/100 ml in viral meningitis compared with 2.64 +/- 2.06 mg/100 ml in bacterial meningitis (P less than 0.01). However, these values overlapped to a considerable extent and, generally, measurement of CSF immunoglobulins did not enhance diagnostic accuracy in this group of children.

The "natural history" of bacterial meningitis, although today a hypothetical event, must be essential reference to interpret the various cerebro-spinal fluid parameters, either in diagnosis or in monitoring. The Authors give first a synopsis of the normal cerebro-spinal fluid. They divide the natural history of bacterial meningitis into five stages, describing the variations in the main parameters (macroscopical, bacteriological, humoral and cytological). The Authors point out also the new bacteriological pathology of leptomeningitis arising from inadeguate therapy: 1) a flare-up of meningitis of form L and 2) bacterial meningitis of "decapitate" type. In 2) the Authors stress the importance in the laboratory of differential diagnosis from aseptic or viral meningitis.

Cerebrospinal fluid (CSF) and serum lysozyme concentrations were determined in infants and children with and without acute infectious disease of the central nervous system. Serum lysozyme values from patients with bacterial and viral meningitis were found within the normal range. Lysozyme activity was absent or very low (below 0.5 microgram/ml) in normal CSF. High levels (4-12 microgram/ml) in patients with viral meningitis. A decrease of the lysozyme activity coincided with the clinical improvement of the bacterial meningitis. The lysozyme activity in CSF should be of significant value in detecting an inflammatory disease of the central nervous system.

The concentration of lysozyme (LZM) in cerebrospinal fluid was determined in 25 patients with bacterial meningitis, in 18 patients with viral meningitis and in 25 control patients who had other fibrile illnesses. The concentration of LZM was less than 1.5 microgram/ml in all control patients, and slightly to markedly raised in 10 patients with viral meningitis and in 11 out of 13 patients with untreated bacterial meningitis. The concentration of LZM was significantly different in the viral and bacterial meningitis patients (p less than 0.001). Most raised concentrations of cerebrospinal fluid LZM persisted for at least one week after the start of antibiotic treatment. The concentrations of LZM correlated well with concentrations of lactic dehydrogenase. These results show that the determination of cerebrospinal fluid LZM is a useful tool in the differential diagnosis of meningitis, particularly when the prehospital treatment with antibiotics may be responsible for a diagnostically misleading negative bacterial culture of the cerebrospinal fluid and altered cerebrospinal fluid cytology.

A retrospective study of 547 cases of meningitis was performed. Of these, 236 were bacterial, 304 were viral, and 7 were fungal in etiology. Of 110 survivors of bacterial meningitis over the age of 2 1/2 years, 23 or 21% suffered partial or complete sensorineural hearing loss. The site of auditory injury in cases of partial loss was the cochlea by audiologic criteria. A positive correlation with hearing loss was found for the species of organism, delay before treatment, low CSF sugar, and CSF pleocytosis. Of 7 patients with fungal meningitis, 3 suffered hearing loss with signs of a retrocochlear site. Of 304 cases of aseptic meningitis, none developed a hearing loss. The pathophysiology of hearing loss as a sequela of meningitis and the possible explanations for absence of hearing loss in viral meningitis are discussed.

The use of antibiotics in viral diseases of childhood is discussed. If bacterial infection is likely, either as superinfection or as part of the differential diagnosis, then antibiotics should be given. The antibiotic of choice for each illness is considered. Respiratory infections are common. The diagnosis and treatment of streptococcal pharyngitis is compared with viral pharyngitis. Penicillin is indicated if the bacterial infection is possible. If there is difficulty in distinguishing between croup and epiglottitis, then chloramphenicol or ampicillin should be given. Otitis media and pneumonia caused by viruses are difficult to differentiate from their bacterial counterparts, and antibiotics are indicated. By contrast, antibiotics are not used in bronchiolitis or asthma. Antibiotics are contraindicated in gastroenteritis even if caused by bacteria. Prolongation of the carrier state or superinfection may then occur. Interpretation of the biochemical and bacteriological findings of the cerebrospinal fluid is important in distinguishing viral meningitis and encephalitis from bacterial meningitis. If bacterial meningitis is possible, then antibiotics should be used. The indications for antibiotics in viral diseases of the skin, eye, joints, heart and parotid are also discussed.

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.

Albumin, IgG, IgA, IgM, transferrin, and alpha 1-antitrypsin were determined quantitatively in the cerebrospinal fluid (CSF) of 44 healthy children and 37 pediatric patients with central nervous system diseases. Neither IgA nor IgM were found in the CSF of normal children, but they were present in cases of purulent and non-bacterial meningitis. In cases of encephalitis all proteins studied were increased except IgA and IgM, which could not be demonstrated. On the basis of the results it may be concluded that the increase of IgG in the CSF in bacterial and a bacterial meningitis is due to an increased permeability of the blood-CSF barrier. Except in cases with ependymitis, IgG is produced only in small amounts in or near the CSF spaces even in the presence of inflammation of the meninges. The quantitative determination of IgG, IgA, and IgM in case of increased CSF protein content may facilitate the differential diagnosis between purulent and acute viral meningitis and encephalitis.

High levels of cerebrospinal fluid (CSF) lactic acid dehydrogenase (LDH) activity were found in 23 cases of bacterial meningitis, but significantly lower levels of CSF LDH activity were observed in 11 patients with viral meningitis and in 13 patients with no central nervous system infection. No correlation was found between levels of CSF LDH activity and specific agents or the amounts of CSF white blood cell, protein, and glucose. The number of meningitis cases of unknown cause that could be classified as probably bacterial or viral was increased by determination of the level of CSF LDH activity. The level of CSH LDH activity is useful in differentiating bacterial from viral meningitis and, along with determination of the CSF blood cell counts and protein and glucose levels, aids in classification of meningitis before culture results are available.
