Concerns about the association of aseptic meningitis with measles-mumps-rubella (MMR) vaccines containing the Urabe Am 9 strain and the increasing worldwide demand for MMR vaccines, prompted the development of a new mumps vaccine strain (RIT 4385) by SmithKline Beecham Biologicals (SB) as part of a trivalent live attenuated MMR vaccine. The present study assessed the immunogenicity and reactogenicity of two lots of 'Priorix' with a widely used and established vaccine M-M-R II (Merck & Co. Inc.) as comparator vaccine. 255 healthy children, 12 to 24 months of age, were enrolled in a single-blind study and randomly allocated to receive a single dose of one of two lots of "Priorix" or M-M-R II vaccine. Vaccinees were followed up for six weeks post-vaccination for solicited and unsolicited symptoms. Immunogenicity was determined in pre- and 60 days post-vaccination sera using commercial immunoassays for measles, mumps and rubella antibodies. There were no significant differences in immune responses between groups for any of the three vaccine components. In initially seronegative subjects, the respective post-vaccination seroconversion rates for 'Priorix' lots 1 and 2, and M-M-R II were 100, 100 and 97.6% for measles antibodies, 91.7, 95.1 and 94% for mumps antibodies and 100, 100 and 100% for rubella antibodies, respectively. GMTs for the three groups were 3,076, 3,641 and 3,173 mIU/ml for measles antibodies, 934, 900 and 1,043 U/ml for mumps antibodies, and 86.4, 87.5 and 97.1 IU/ml for rubella antibodies, respectively. The incidence of local symptoms was significantly lower for both 'Priorix' lots (17.6 and 15.3% for lots 1 and 2, respectively) than for M-M-R II (37.6%). Fever > or = 38.1 degrees C during the six-week observation period occurred in approximately 25% of all subjects in all groups with no differences between the groups. No parotid/salivary gland swelling or signs of suspected meningism were reported, and there were no serious adverse events related to vaccination. The new MMR vaccine 'Priorix' containing the new RIT 4385 mumps strain was safe and had a significantly improved local tolerability profile over the comparator vaccine, M-M-R II, while eliciting an at least equivalent immune response.

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.
