Chryseobacterium meningosepticum is an uncommon pathogen causing adult bacterial meningitis. Herein, we report the case history of one 21-year-old woman with this uncommon central nervous system infection. A diagnosis of adult C. meningosepticum meningitis can only be confirmed by a positive cerebrospinal fluid (CSF) culture. The patient had insulin-dependent diabetes mellitus as the underlying condition associated with this infection. The clinical presentations were fever, headache, consciousness disturbance, and seizure. CSF analysis revealed a purulent inflammatory reaction. After a 21-day course of intravenous cefepime (6 g/day) treatment, this patient was discharged in a state of complete recovery.

The epidemiologic landscape of causative pathogens and clinical characteristics of bacterial meningitis varies with several clinical factors including preceding/pre-existent medical and/or surgical conditions, modes of contraction, geographic distributions, status of vaccinations, the study time periods and differences among age groups. In order to delineate the epidemiology of bacterial meningitis in senior adults (ages > or =60 y/o) in southern Taiwan, we analyzed the clinical characteristics and therapeutic outcomes of 64 senior adults (42 men and 22 women, aged 60-80 years) with bacterial meningitis collected over a period of 13 years at our hospital. The prognostic factors between fatal and non-fatal groups of patients were compared. Twenty-seven of the 64 patients belonged to a nosocomial infection group, and the other 37 comprised a community-acquired infection group. Sixty percent (39/64) of the patients had a post-neurosurgical state as the most preceding event prior to infection. Liver disease (13) and diabetes mellitus (6) were the most common underlying conditions of the other 25 patients with spontaneous meningitis. Of these 64 patients, Klebsiella (K.) pneumoniae (18), Acinetobacter baumannii (5), Escherichia coli (5), and Enterobacter species (5) were the most commonly implicated Gram-negative pathogens. Staphylococcus (S.) aureus infection was increasing during the study period. The therapeutic results of this group of patients showed a mortality rate of 38% (24/64). The presence of septic shock was the most significant prognostic factor. In conclusion, for this study group, a post-neurosurgical state was the single most important preceding event for senior adults developing bacterial meningitis. Of the implicated pathogens, K. pneumoniae and S. aureus were the most common gram-negative and gram-positive pathogens, respectively. The therapeutic result of this specific group of patients showed a high mortality rate; however, the small case number and possible bias of case selection have limited the analytical conclusions of this study.

The aim of this study was to assess mortality and sequellae within cases from Nationwide survey of community acquired meningitis and identify risk factors for inferior outcome. Risk factors such as underlying disease (diabetes mellitus, cancer, trauma, neonatal age, splenectomy, alcoholism, sepsis, other infections), etiology, clinical symptoms and outcome (death, improvement and cured after modifications of ATB therapy, cured without change of therapy, cured with neurologic sequellae) were recorded and analysed with univariate analysis (chi2 or t test for trends, CDC Atlanta 2004). Analysing risk factors for inferior outcome (death or cured with neurologic sequellae), we compared patients who died or survived with neurologic sequellae to all patients with community acquired bacterial meningitis. Univariate analysis showed that trauma (p<0.05), alcohol abuse (p<0.05), diabetes, S. aureus (p<0.05) and gram-negative etiology (A. baumannii, Ps. aeruginosa or Enterobacteriaceae) (36% vs. 11,9%, p<0.05) were predicting inferior outcome. Analysing risk factors for treatment failure (death or failed but cured after change of antibiotic treatment) prior sepsis (34.1% vs. 13.9%, p<0.01) and gram-negative etiology (25% vs. 11.9%, p<0.02) were statistically significant predictors of treatment failure. Neisseria meningitis had less failures (p<0.05). Concerning infection associated mortality again diabetes mellitus (p<0.05), alcoholism (p<0.05) staphylococcal and gram-negative etiology (p<0.05) were significant predictors of death. N. meningitis had surprisingly less treatment failures (appropriate and rapid initial therapy). Neurologic sequellae were more common in patients with alcohol abuse (p<0.05), craniocerbral trauma (p<0.05) and less common in meningitis with pneumococcal etiology (p<0.05).

The aim of this study was to assess if differences in etiology and risk factors among 372 cases of bacterial meningitis acquired after surgery (PM) or in community (CBM) have impact on outcome of infected patients. Among 372 cases of bacterial meningitis within last 17 years from 10 major Slovak hospitals, 171 were PM and 201 CBM. Etiology, risk factors such as underlying disease, cancer, diabetes alcoholism, surgery, VLBW, ENT infections, trauma, sepsis were recorded and mortality, survival with sequellae, therapy failure were compared in both groups. Significant differences in etiology and risk factors between both groups were reported. Those after neurosurgery had more frequently Coagulase negative staphylococci (p<0.001), Enterobacteriaceae (p=0.01) and Acinetobacter baumannii (p=0.0008) isolated from CSF and vice versa Streptococcus pneumoniae (p<0.001), Neisseria meningitis (p<0.001) and Haemophillus influenza (p=0.0009) were more commonly isolated from CSF in CBM. Neurosurgery (p<0.001), sepsis (p=0.006), VLBW neonates (p=0.00002) and cancer (p=0.0007) were more common in PM and alcohol abuse (p<0.001) as well as otitis/sinusitis (p<0.001) and Roma ethnic group (p=0.001) in CAM. Initial treatment success was significantly more frequently observed among CAM (p<0.001) but cure after modification was more common in PM (p=0.002). Therefore outcome in both groups was similar (14.6% vs. 12.4%, p=NS).

We investigated how many cases of bacterial meningitis in our national survey were associated with sinusitis or otitis media. Among 372 cases of bacterial meningitis within our nationwide 17 years survey, 201 cases were community acquired (CBM) and in 40 (20%) otitis media or sinusitis acuta/chronica were reported 1-5 weeks before onset of CBM. Diabetes mellitus (20% vs. 7.5%, p=0.01), alcohol abuse (35% vs. 15.4%, p=0.003) and trauma (30% vs. 14.9%, p=0.02) were significantly associated with CBM after ENT infections. Concerning etiology, CBM after sinusitis/otitis was insignificantly associated with pneumococcal etiology (50% vs. 33.8 %, NS) and significantly associated with other (L. monocytogenes, Str. agalactiae) bacterial agents (9.9 % vs. 25 %, p=0.008) . However those significant differences for new ENT related CBM had no impact on mortality (12.4 % vs. 5%, NS), failure after initial antibiotics (10 % vs. 9.5%, NS) and neurologic sequellae (12.5 % vs. 15.4 %, NS).

Within last 17 years we went through all charts of bacterial meningitis within our nationwide survey and among 372 cases we found 62 cases of MM, in 12 cases with meningococcal disease (with shock, petechial effusions or disseminated intravascular coagulation or digital gangrenes). MM was usually observed in young adults without any of investigated risk factors like neoplasia, ENT (ear, nose, throat) focuses, elderly age, sepsis, diabetes, alcoholism, trauma, neonatal VLBW etc. Trauma, diabetes mellitus, alcohol abuse and chronic sinusitis/otitis were significantly less frequently found as a risk factor for MM. Mortality was very low, only 4.8% and was lower than overall mortality in CBM (12.4%, NS). Also the proportion of neurologic sequellae (9.7%) and initial treatment failure (8.1%) were comparable or even lower. This positive outcome results are probably because all N. meningitis strains were susceptible to penicillin, chloramphenicol, cefotaxim, cotrimoxazol or ciprofloxacin. Other reason for low mortality was that most cases received oral antibiotic immediately, even before admission (50 of 62). 95.2% of cases survived, 90.3% without any transient neurological residual symptoms.

Meningitis associated with bacteremia is rare. Bacteremic form of meningitis occurred in 28 of 201 cases of community acquired meningitis (14%) in Slovakia within last 17 years. Bacteremic meningitis was associated with diabetes (21.4% vs. 7.5%, p=0.02) and with higher treatment failures (32.1% vs. 9.5%, p=0.01) and higher mortality (25% vs. 12.4%, NS). In univariate analysis comparing 28 cases of bacteremic community acquired bacterial meningitis (BCBM) to all CBM, no significant risk factor concerning underlying disease (cancer, ENT infection, alcohol abuses, trauma, splenectomy, etc.) or etiology was observed apart of diabetes mellitus, which was more common among bacteremic meningitis (21.4% vs. 7.5%, p=0.02). Mortality (25% vs. 12.4%, NS) insignificantly but therapy failure (32.1% vs. 9.5%, p=0.01) was significantly more frequently observed among meningitis with bacteremia. N. meningitis was the commonest causative agent (8 of 28 cases) followed by Str. pneumoniae (6), gram-negative bacteria (6), S. aureus (4) and H. influenzae (2).

Wound infections after tooth extraction may occur in up to 5%. A systemic infection is a rare but threatening complication often caused by an underlying immune deficiency (immunosuppression, diabetes, HIV) which requires prompt adequate care. This case report describes bacterial meningitis as a possible systemic complication two days after the extraction of a molar in a patient with previously undiagnosed latent diabetes mellitus.

Clinical characteristics, etiologies, evolution, and prognostic factors of community-acquired bacterial meningitis in elderly patients are not well known. To improve this knowledge, all episodes of community-acquired bacterial meningitis were prospectively recorded and cases occurring in patients >or=65 years old were selected. During the period 1977-2006, 675 episodes in adults (aged >or=18 yr) were recorded, with 185 (27%) in patients aged >or=65 years old; 76 were male and 109 were female, with a mean age of 73 +/- 6 years (range, 65-93 yr). Causative microorganisms were Streptococcus pneumoniae 74, Neisseria meningitidis 49, Listeria monocytogenes 17, other streptococcal 9, Escherichia coli 6, Haemophilus influenzae 4, Klebsiella pneumoniae and Staphylococcus aureus 2 each, Capnocytophaga canimorsus and Enterococcus faecalis 1 each, and unknown in 20. On admission 91% had had fever, 32% were in a coma (Glasgow Coma Scale <or=8), 9% presented with seizures, and 8% with shock. Thirty patients (16%) presented with seizures during therapy. Mortality was 58/185 (31%). Compared with patients aged 18-65 years, there were significant differences among older patients (aged >or=65 yr), who showed a higher frequency of diabetes and malignancy as underlying disease; pneumonia, otitis, and pericranial fistula as predisposing factors; and S. pneumoniae and L. monocytogenes as etiology. There were also differences in clinical presentation, complications, sequelae, and mortality. Factors independently related with mortality were age, pneumonia as a predisposing factor, coma on admission, and heart failure and seizures after therapy. Dexamethasone therapy was a protective factor. In conclusion, bacterial meningitis in elderly patients is associated with greater diagnostic difficulties and neurologic severity and more complications, as well as with increased mortality. Antiseizure prophylaxis might be useful in these patients.
