In the immunocompromised patient, even mild forms of any combination of headache, meningismus, altered mental status, or focal neurologic signs should initiate an evaluation for possible CNS infection. The limited signs and symptoms of acute CNS infection are not due to specific organisms but to pathologic changes at the neuroanatomic site of infection. The initial clinical history, examination, laboratory, and neuroradiographic data will narrow the problem to one of several groups of agents, although it may not be possible to specify a single causative agent. It should be remembered that several concurrent infections (i.e., CMV and toxoplasmosis, aspergillosis, and bacterial sepsis) may be present. Thus, the clinician should rely on broad antibiotic coverage appropriate to the suspected causative agent or agents at the site of infection. It may be necessary to offer broad-spectrum antibiotic coverage for a CSF presentation that is subsequently found to result from a viral illness or from a noninfectious cause. However, one should avoid undertreating those infections for which specific therapy can be offered, and broad-spectrum treatment usually will not be regretted. Uncertainty in diagnosis following noninvasive procedures should lead to a brain biopsy. Although many of the infections discussed in this article have a poor prognosis, some of the most common pathogens, such as Cryptococcus, Listeria, and Toxoplasma, have effective specific therapies to which the patient should have access as rapidly as possible. The clinician who has successfully treated a patient with CNS infection should remain vigilant for late sequelae or recurrence of infection. Chronic treatment of some infections, such as toxoplasmosis or aspergillosis, may be necessary. The reintroduction of steroids for the treatment of an underlying cancer may reactivate previously treated disease, such as cryptococcosis, and periodic CSF surveillance is appropriate under these circumstances. Recurrence of the symptoms should raise the suspicion of recurrent or new infection, and the patient also should be evaluated with CT or MRI for the development of hydrocephalus or for new metastatic disease. In patients who have had varicella-zoster infection, postherpetic neuralgia and delayed arteritis may develop. Seizures, hearing loss, and neuropsychologic sequelae may follow any meningoencephalitis. The patient should always be reevaluated for the possibility of infection with a different opportunistic organism. CNS infections remain a major cause of morbidity and mortality in immunosuppressed patients with malignancies. In one series, 60% of such patients died as a result of their CNS infection, many at a time when the underlying disease had an otherwise good prognosis.(ABSTRACT TRUNCATED AT 400 WORDS)

The symptoms and clinical course of meningococcaemia in 14 cases are described; 10 patients died; in one of the four survivors amputations were inevitable for necrosis of hands and feet. The foremost symptoms at the first time that a doctor was contacted were fever, lethargy, petechiae and purpura. The fulminant course is shown by the high number of resuscitation at the time of admission or in the first hours after admission, and by the time between first symptoms and death. The mortality of meningococcaemia is mostly not due to meningitis. Most patients die of septic shock even before signs of meningitis can develop. The early signs of meningococcaemia are not those of meningitis, but those of sepsis. Meningism and headache are rare symptoms. The severest symptoms are fever and lethargy, in combination with petechiae and purpura. The fulminant course of the disease requires immediate admission. Treatment of infection and septic shock may be lifesaving.

Meningococcemia caused by serogroup W135 occurred in four patients during a period of nine months. Three of the patients had hypogammaglobulinemia with normal hemolytic complement levels; the fourth had normal immunoglobulin levels one year after her illness. None of the patients had classic meningitis. One patient had pneumonia; one appeared to have encephalitis with mild meningismus; and two had sepsis without localizing signs or symptoms. Patients with hypogammaglobulinemia are predisposed to the development of meningococcemia, and the incidence of W135 carriage in the population is increasing.

Sixty-seven patients with brain abscess were managed over 19 years (1975-1993). Our series had a 2.5 to 1 male predominance; the age distribution was from 3 days to 81 years. The underlying conditions of hematogenic brain abscesses (n = 33; 49%) included lung infections (n = 16), heart disease (n = 4), sepsis (n = 10), and other foci (n = 3). Otolaryngologic infections led to the abscess in 10 cases; there were 9 traumatic abscesses. The causes remained unknown in 15 cases. There were 47 solitary abscesses (70%) and 20 multiple abscesses. The most frequent presenting signs and symptoms were neurologic deficits (n = 17), disturbances of consciousness (n = 14), seizures (n = 6), and headaches, meningism and vomiting (n = 13). Causative organisms were isolated in 39 cases (58%) and included staphylococci (n = 6), streptococci (n = 6), enterobacteriae (n = 2), and anaerobic pathogens (n = 9). The most reliable laboratory sign of inflammation was an elevated ESR (52/59 patients). With the advent of computed tomography, burr hole aspiration of the abscess with or without drainage was possible in 30 cases; the mortality in this subgroup was 9%. All 4 patients with surgical excision in the pre CT-era died. The mortality of patients treated with antibiotics only was 62% (18/29). Overall mortality was 37% (25/67), including 5 cases with post mortem-diagnosis of brain abscess. Good recovery was achieved in 29/42 survivors. Predictors of a poor outcome were the patient's age, the level of consciousness, multiple abscesses, polybacterial cultures, and a hematogenic etiology, but not the size of the abscess.

We report an analysis of clinical course of 18 patients presenting with Staphylococcus aureus sepsis. Community acquired infection was caused by Methicillin susceptible S. aureus (MSSA) in 11 patients. MSSA in 3 and Methicillin Resistant S. aureus strains (MRSA) in 4 patients, were the etiologic factor in 7 patients with nosocomial infection. From anamnestic data patients presented with: elevated body temperature--18/18, arthralgia and myalgia--9/18, headache--8/18, nausea--6/18, chills--2/18. Physical examination on admission revealed: meningismus--12/18, hepatomegaly--11/18, purulent and haemorrhagic skin lesions--7/18 and impaired neurological status (Glasgow Coma Scale < or = 12)--6/18. The mean APACHE III score, calculated from data collected at diagnosis of sepsis was 47 (7-114). Several complications had been observed: endocarditis--10, purulent meningitis--5, focal CNS lesions--5, pneumonia--8, pulmonary abscess--3, hydrothorax--1, abscesses of the spleen--5, renum--4, osteomyelitis--2. 11/18 patients required ICU treatment. Ventilator assistance of respiration was necessary in 7/18. Acute thrombocytopenia (< 100,000/ml) was diagnosed in 60%. In 5 patients suppurative meningitis had been diagnosed with a mean pleocytosis-837 (173-1898) microL. The results of treatment were satisfactory in 11 patients, 3 patients required further surgical treatment (2--cardiosurgery, 1--orthopedic surgery), 4 patients died. Infection caused by community acquired MSSA strains had been characterized by severe clinical course with increased incidence of endocarditis, organ failure and abscess forming. We conclude that Staphylococcus aureus sepsis is still a life-threatening disease, which should be treated at centers with immediate access to imaging techniques of CNS and circulatory system as well as intensive care and cardiosurgery. Community acquired S. aureus sepsis compared with nosocomial infection is characterized by more severe clinical course and higher mortality, despite of a great susceptibility to most antibiotics of causative S. aureus strains.

Infection of an intrathecal pump system is a rare but serious complication and usually leads to the removal of the pump. The authors report the first case of methicillin-resistant Staphylococcus aureus (MRSA) meningitis in a patient with such a pump successfully treated with linezolid without the need for removal of the intrathecal pump. A 77-year-old woman with cervical myelopathy underwent implantation of an intrathecal pump system for baclofen administration. Two weeks after the procedure she developed meningitis caused by MRSA as isolated in cerebrospinal fluid (CSF) cultures, blood samples, and serum obtained from the pump pouch. Clinically she presented with meningism, somnolence, and signs of sepsis. When a combined intravenous antibiotic treatment regimen of vancomycin and rifampicin resulted in no clinical improvement, that regimen was discontinued and linezolid was administered intravenously as monotherapy. Within 3 days clinical and laboratory findings showed significant improvement. After 1 week of linezolid treatment, blood and CSF cultures were sterile. Intravenous treatment was administered for a total of 3 weeks, after which the patient was treated with oral linezolid for 3 months. During 18 months of follow-up, no new clinical or laboratory signs of infection were observed. These results confirm previous reports of the efficacy of linezolid for the treatment of severe infections of the central nervous system caused by multidrug-resistant Gram-positive bacteria, especially postneurosurgical infections.

Bacterial meningitis and meningococcal sepsis are rare in adults. Any diagnostic delays with subsequent delay to treatment can have disastrous consequences. The decline in bacterial meningitis over the past few decades has not been accompanied by a reduction in case fatality rate which can be as high as 20% for all causes of bacterial meningitis and 30% in pneumococcal meningitis. The classic triad of neck stiffness, fever and altered consciousness is present in < 50% of cases of bacterial meningitis. Patients with viral meningitis also present with signs of meningism (headache, neck stiffness and photophobia) possibly with additional non-specific symptoms such as diarrhoea or sore throat. Suspected cases of meningitis or meningococcal sepsis must be referred for further assessment and consideration of a lumbar puncture. Most patients will fully recover. However, the sequelae of bacterial meningitis and meningococcal disease can be disabling. Many patients feel well at discharge and do not realise that they may not be able to return to all their normal duties and activities straightaway. Fatigue, headaches, sleep disorders and emotional problems are often reported in the weeks and months after discharge.
