The usefulness of CRP in early detection of neonatal septicemia/meningitis and urinary tract infection was studied in a neonatal unit using a semiquantitative latex-agglutination as a rapid screening method, and electroimmuno assay as reference method for CRP determination. In 94% of non-infected infants CRP was less than or equal to 15 mg/l and 82% had CRP less than 10 mg/l up to 3 days of age. After 3 days of age 96% had CRP less than 10 mg/l. The initial CRP level was increased in 16 out of 18 patients (89%) with bacterial septicemia. Low CRP was seen in one patient with total agranulocytosis and septicemia from Streptococcus type B and in one patient with Staphylococcus albus sepsis. A rise in CRP was also seen in very pre-term infants with septicemia. Increased initial CRP was uncommon in neonatal urinary tract infection (2 of 9), but a rise was seen in 3 additional patients. A comparison between CRP, total neutrophil blood cell count and band neutrophil count as diagnostic parameters was in favour of CRP at this early stage of infection. CRP is of definite value as an aid in early diagnosis of neonatal septicemia and bacterial meningitis.

The incidence of craniotomy infections, usually less than 5%, is dependent on many factors, such as how the information is collected and how the percentage is calculated. Because these factors may vary from report to report, incidence figures should be read with skepticism. It is difficult to prove that a given factor contributes to infection. Most routines are based more on personal convictions than on solid evidence. CSF leak is one factor known to have great impact; it should be avoided with painstaking technique and, if it occurs, it should be treated promptly. Solid evidence favoring prophylactic antibiotics for persistent CSF leak is not available; but, until a well-designed randomized study tells otherwise, the high risk of meningitis justifies prophylaxis. Penicillin is adequate for leaks through the nose or the ear. For leaks through the skin, the antibiotic should be effective against staphylococci. The infection register should provide information about prevailing bacteria. In many hospitals, the prophylaxis should cover gram-negative bacilli. CRP is a useful diagnostic aid for detecting postoperative infections. The operation, however, also causes a CRP rise. Daily CRP monitoring, at least for patients with elevated temperature, is recommended. The third-generation cephalosporins are a welcome contribution to the treatment of bacterial meningitis. To avoid side effects, and to keep them potent when they are really needed, they should be used with caution. Most postoperative cases of meningitis are in fact aseptic. If the patient is moderately ill, chloramphenicol is still eligible as the first choice antibiotic. When the bacterial culture is negative, the antibiotic should be stopped. The standard treatment for bone flap infection is removal of the bone flap. The bone flap is essentially devascularized and comparable to a foreign body. The justification of vancomycin prophylaxis has been shown in a randomized study.

The duration of antibiotic treatment of bacterial meningitis is always a topical issue. In our study (58 children), 21 of 24 meningococcal meningitis were treated for 4 or 5 days, 16 of 22 Haemophilus influenzae and 4 of 6 pneumococcal meningitis were treated for 7 days without increase in neurologic sequelae. A return of blood CRP levels to normal values was observed in all these patients simultaneously. Thus, CRP seems to be a good biological parameter for discussing treatment discontinuation. Furthermore, in some complications such as subdural effusion, a new increase of CRP levels was observed after the 5th day. A sequential follow-up of CRP levels at days J0, 5, 7, 10, seems a very useful tool for management of bacterial meningitis.

The authors report a case of partially thrombosed giant aneurysm which was secondarily infected with purulent meningitis. The relationship between the infection of the aneurysm, the rapid growth of the aneurysm and the development of severe cerebral edema was discussed. A 53 year-old man was admitted on September 1, 1986, with a diagnosis of bacterial meningitis. On his admission, his body temperature was 39 degrees C, and he showed mental confusion but no neurological deficits. Laboratory data revealed signs of infection in white blood cell count, CRP, and erythrocyte sedimentation rate. Computerized tomographic (CT) scan and magnetic resonance (MR) imaging showed a massive round mass with perifocal edema measuring 40mm in the maximum diameter in the left paramedian frontal region. T1 weighted MR image also showed the presence of pus accumulation in the left ventricle. Cerebral angiography demonstrated a giant aneurysm at the distal portion of the azygos anterior cerebral artery, and irregular narrowing of both the supraclinoid segment of the carotid artery and its main branches indicating arteritis due to purulent meningitis. The patient was treated with ventricular drainage and administration of antibiotics. Culture of the purulent CSF was negative. The patient's lab data, CSF finding and neurological status improved progressively. However, follow-up CT scan and angiogram a month later showed enlargement of the aneurysm, dilatation of the patent lumen and perifocal edema. On October 8, the patient suddenly became comatose with anisocoria. A CT scan showed massive edema with marked midline shift. Emergency bifrontal craniotomy was carried out, and clipping was completed after removal of the thrombosed portion of the aneurysm, and thromboendarterectomy of the aneurysmal neck.(ABSTRACT TRUNCATED AT 250 WORDS)

Cerebrospinal fluid C-reactive protein (CSF-CRP) was studied in 183 consecutive infants and children with suspected meningitis, using a nephelometric technique. Cerebrospinal fluid C-reactive protein was above an empirically chosen level of 1 mg/1 in seven of 19 children with culture-proven bacterial meningitis, in only one of 15 children with viral meningitis, and three of 139 children with no meningitis. All 10 children with partially treated meningitis had CSF-CRP levels below 1 mg/1. There was good correlation between CSF-CRP and total protein levels in children with bacterial meningitis (R value 0.4999 P less than 0.05). The test was not sensitive enough for early differentiation between bacterial and viral meningitis. The test also did not add extra information regarding aetiology in partially treated meningitis.

We have studied prospectively the C-reactive protein values in the cerebrospinal fluid of 54 patients with bacterial meningitis, tuberculous meningitis, and severe malarial infection and convulsions without infections of the central nervous system. CSF CRP above 1 mg/l was observed in 23 out of 28 patients with bacterial meningitis (sensitivity of 82%). The specificity was 73% at the 1 mg/l level. Five out of 19 patients with severe malarial infection had CSF CRP levels above 1 mg/l. Two patients with TB meningitis were also studied. Both of them had CSF CRP above 1 mg/l. Five patients with febrile convulsions or sepsis without meningitis had CSF CRP below 1 mg/l. It is concluded that CSF CRP would not be used as a useful discriminatory test in areas where malaria and TB meningitis are common.

The value of cerebrospinal fluid C-reactive protein (CSF CRP) determination as a diagnostic aid in infective meningitis has been investigated in four groups of children. In a "no meningitis" group of 10 children, a median CSF CRP value of 0.08 micrograms/ml was obtained (range 0 to 0.31 micrograms/ml); in a viral meningitis group of 21 children a median value of 0.01 micrograms/ml (range 0 to 3.06 micrograms/ml); in a bacterial meningitis group of 27 children a median value of 9.6 micrograms/ml (range 0 to 31.5 micrograms/ml); and in a tuberculous meningitis group of 18 children a median value of 0.29 micrograms/ml (range 0 to 4.9 micrograms/ml). CSF CRP values in the bacterial meningitis group differed significantly from those of each of the other groups (P less than 0.01), but considerable overlap between the groups detracted from the diagnostic value of the test. In six patients with bacterial meningitis with ambiguous conventional CSF chemistry results, normal CSF CRP values were found. Simultaneous serum CRP was determined in nine patients with tuberculous meningitis and 11 with bacterial meningitis, and the CRP response in both the serum and CSF appears subdued in tuberculous meningitis in comparison with bacterial meningitis. CSF CRP and total protein values were determined intermittently during a 24-hour period in ventricular CSF from two children with tuberculous meningitis who underwent temporary direct ventricular drainage. A considerable and apparently parallel diurnal variation in both values was seen. CSF CRP values have limited application in the etiologic diagnosis of meningitis.

Twenty-eight bacteriologically proved episodes of purulent meningitis in 27 infants and children were monitored prospectively with sequential determinations of serum C-reactive protein. Except in one rapidly fatal case, all the patients showed decreasing CRP values for about 1 week. In five patients the CRP values than returned to a high level (P less than 0.001). Each of these patients developed an organic complication (subdural effusions in three, transient widening of the ventricles in one, purulent arthritis with osteomyelitis in one). Except for one infant with sensorineural hearing loss, which probably had developed early in the course of meningitis, no permanent sequelae were found in the patients with uncomplicated courses. One infant later had a relapse of Escherichia coli meningitis, reflected in a sharp increase of CRP. We conclude that sequential CRP measurements may be performed routinely to detect potential complications at an early stage of bacterial meningitis.

The ability of serum C-reactive protein (S-CRP) to differentiate between acute bacterial and viral meningitis was evaluated in 235 patients, both children and adults. The patients underwent lumbar puncture due to suspected central nervous system (CNS) infection. In patients with bacterial meningitis, 7/60 (12%) had S-CRP concentrations below 50 mg/l. Of these patients, 4 were children below 6 years of age, all with symptoms of meningitis for less than 12 h before admission and 3 adults of whom 1 had symptoms of meningitis for less than 12 h. In patients with viral meningitis, 15/146 (10%) had S-CRP concentrations above 50 mg/l. Only 3 children below 6 years of age with viral meningitis had S-CRP concentration above 20 mg/l, but none exceeded 50 mg/l. An S-CRP value above 50 mg/l in patients with CSF pleocytosis usually indicates bacterial etiology. However, S-CRP values above 50 mg/l may occasionally be seen in viral meningitis. In children younger than 6 years of age a discriminatory level for S-CRP of 20 mg/l can be used to distinguish between bacterial and viral meningitis, but for older patients a discriminatory level of 50 mg/l is more appropriate. If the duration of the illness is less than 12 h, S-CRP concentrations below the discriminatory levels are of limited diagnostic value.

In order to assess the benefits of serial assays of C-reactive protein in the course of bacterial meningitis in adults, daily blood samples were taken for CRP measurement during 10 days in 21 consecutive patients (mean age: 24 +/- 8 years) hospitalized for bacterial meningitis principally due to Neisseria meningitidis (n = 15). The highest CRP level (178 +/- 38 mg/l) was present on admission, followed by a regular decrease occurring in uncomplicated meningitis until normal level was achieved on day 9. The CRP kinetics was not influenced by the type of causative micro-organism. This study shows that CRP kinetics in adults is similar to that reported in children. The benefit of CRP assays in optimizing the duration of antibiotic treatment of meningitis needs to be more carefully assessed.
