Neisseria meningitidis is a leading cause of bacterial meningitis and sepsis in children and young adults in the United States and is spread through direct contact with respiratory secretions. Persons in close contact with patients who have meningococcal disease are at increased risk for contracting the disease. Commercial aircraft are suitable environments for the spread of airborne pathogens, including N. meningitidis. A case of air-travel-associated meningococcal disease is defined as a patient who meets the case definition of meningococcal disease within 14 days of travel on a flight of at least 8 hours duration. Because of concerns about disease transmission aboard aircraft, CDC has developed recommendations to ensure a standard approach to management of airline contacts. This report presents a case of air-travel-associated meningococcal disease and presents guidelines for the management of persons potentially exposed to meningococcus during airtravel.

The levels of C-reactive protein (CRP) and serum amyloid A protein (SAA) in blood are increased in patients with inflammatory diseases as acute phase proteins. Most of the presently used indicators of inflammation, such as body temperature, white cell count, erythrocyte sedimentation rate or CRP, are non-specific parameters. In contrast, procalcitonin (PCT) has been reported to be selectively induced by severe bacterial infection during the systemic inflammatory response syndrome (SIRS), and also in sepsis or multiorgan dysfunction syndrome. PCT expression is only slightly induced, if at all, by viral infections, autoimmune disorders, neoplastic diseases and trauma of surgical intervention. We measured the concentrations of CRP, SAA and PCT in the sera and cerebrospinal fluid (CSF) of 30 patients with bacterial, viral, or mycotic meningitis, and 12 patients with a noninflammatory central nervous system disease as controls. An extremely high CRP level in CSF of above 100 microg/L was seen in all seven bacterial meningitis patients and in only 10% of the viral meningitis patients. A high SAA level in CSF of greater than 10 microg/L was observed in all of the bacterial meningitis and mycotic meningitis patients, and in 95% of the viral meningitis patients. Among those with bacterial meningitis, the serum PCT level was more elevated in those with more serious bacterial meningitis. The PCT level in the CSF did not significantly differ among the patients with the three types of meningitis. However, the serum PCT level was very high above 0.1 microg/L in all seven bacterial meningitis patients, especially in the clinically serious cases.

Antimicrobial therapy must start promptly. Antimicrobial regimen is adapted to the data of epidemiological trends. Bacterial meningitis of children are a matter of therapeutical urgency. Diagnosis must be easily considered according to the clinical analysis. Fulminant meningococcal sepsis is the most alarming clinical presentation of the meningococcal diseases.

Neisseria meningitidis is a leading cause of bacterial meningitis and sepsis among older children and young adults in the United States. N. meningitidis usually is transmitted through close contact with aerosols or secretions from the human nasopharynx. Although N. meningitidis is regularly isolated in clinical laboratories, it has infrequently been reported as a cause of laboratory-acquired infection. This report describes two probable cases of fatal laboratory-acquired meningococcal disease and the results of an inquiry to identify previously unreported cases. The findings indicate that N. meningitidis isolates pose a risk for microbiologists and should be handled in a manner that minimizes risk for exposure to aerosols or droplets.

Haemophilus influenzae type b (Hib) was the leading cause of bacterial meningitis and a major cause of other serious invasive diseases among children aged <5 years in the United States before Hib conjugate vaccines became available in 1988. In 1991, all infants starting at age 2 months were recommended to receive Hib conjugate vaccines; by 1996, incidence of Hib invasive disease (i.e., illness clinically compatible with invasive disease, such as meningitis or sepsis, with isolation of the bacterium from a normally sterile site) among children aged <5 years had declined by >99%. This report presents 1998-2000 Haemophilus influenzae (Hi) surveillance data, which indicate that the incidence of reported Hib invasive disease remains low. Achieving the national health objective for 2010 of reducing to zero indigenous Hib invasive disease cases in children aged <5 years will require improved age-appropriate vaccination of children, complete reporting of vaccination and relevant medical histories, standardization of the serotyping procedure, and complete ascertainment and reporting of serotype for all Hi invasive disease cases.

Neisseria meningitidis is a major cause of bacterial meningitis and sepsis. Polysaccharide-protein conjugate vaccines for prevention of group C disease have been licensed in Europe. Such vaccines for prevention of disease caused by groups A (which is associated with the greatest disease burden worldwide), Y, and W135 are being developed. However, conventional approaches to develop a vaccine for group B strains, which are responsible for most cases in Europe and the USA, have been largely unsuccessful. Capsular polysaccharide-based vaccines can elicit autoantibodies to host polysialic acid, whereas the ability of most non-capsular antigens to elicit broad-based immunity is limited by their antigenic diversity. Many new membrane proteins have been discovered during analyses of genomic sequencing data. These antigens are highly conserved and, in mice, elicit serum bactericidal antibodies, which are the serological hallmark of protective immunity in man. Therefore, there are many promising new vaccine candidates, and improved prospects for development of a broadly protective vaccine for group B disease, and for control of all meningococcal disease.

In recent years, viridans streptococci have been reported with increasing frequency to cause infections in neutropenic cancer patients. Streptococcus mitis, one of the species included among viridans streptococci, is the most resistant to beta-lactam antibiotics in this group. Bacterial meningitis presenting without pleocytosis in the cerebrospinal fluid (CSF) is rare, and this situation could be confusing to physicians. It is also an uncommon infectious complication in leukemic patients with neutropenia. In patients with leukopenia caused by myelosuppression after chemotherapy, bacterial meningitis must be considered a possibility when a patient develops meningeal signs, even if no pleocytosis is found in the CSF. We report on a 6-year-old boy with leukemia and neutropenia who developed sepsis and meningitis caused by S. mitis with high-level resistance to penicillin and cephalosporins (MIC of both, >2 mg/l); he was a long-term survivor receiving chronic trimethoprim-sulfamethoxazole prophylaxis. The patient was successfully treated with a combination of vancomycin, ceftriaxone, and granulocyte-colony-stimulating factor.

Corticosteroids were proposed to treat patients with severe sepsis as early as 1940. A summary of all available randomized controlled trials performed between 1966 and 1993 was provided in two systematic review that recommended to abandon the use of high dose coricosteroids to treat patients with severe infection. Nonetheless, a doubt still persist regarding the efficacy of a strategy of replacement therapy in cathecolamines-dependent shock. This strategy relies mainly on the concept that septic shock may be complicated by 1) an occult adrenal insufficiency, 2) a glucocorticoid peripheral resistance syndrome. Some studies demonstrated the effect of replacement therapy with hydrocortisone on the sistemic inflammatory response and on the cardiovascular function during sepsis. The effect of this therapy on survival to septic shock is controversial both in recent and old studies. Finally a recently completed multicenter, placebo controlled, randomized, double-blind study has evaluated the efficacy and tolerance of a replacement therapy with a combination of hydrocortisone (50 mg intravenous bolus four times per day) and fludrocortisone (50 g orally once a day) given for 7 days. This study included 300 catecholamines- and ventilator-dependent septic shock. The authors found a significant reduction in 28-day mortality in patient with occult renal insufficiency. In sum, short course with high doses of corticosteroids should not be given in severe sepsis, except for specific entitles like severe typhoid fever, pneumocystis carinii pneumonia in AIDS or bacterial meningitis in children. The rational for a replacement therapy with hydrocortisone in catecholamines-dependent septic shock grows stronger.

Throughout the history of mankind, infectious diseases have remained a major cause of death and disability. Although industrialized nations, such as the United States, have experienced significant reductions in infection-related mortality and morbidity since the beginning of the "antibiotic era," death and complications from infectious diseases remain a serious problem for older persons. Pneumonia is the major infection-related cause of death in older persons, and urinary tract infection is the most common bacterial infection seen in geriatric patients. Other serious and common infections in older people include intra-abdominal sepsis, bacterial meningitis, infective endocarditis, infected pressure ulcers, septic arthritis, tuberculosis, and herpes zoster. As a consequence, frequent prescribing of antibiotics for older patients is common practice. The large volume of antibiotics prescribed has contributed to the emergence of highly resistant pathogens among geriatric patients, including methicillin-resistant Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae, vancomycin-resistant enterococci, and multiple-drug-resistant gram-negative bacilli. Unless preventive strategies coupled with newer drug development are established soon, eventually clinicians will be encountering infections caused by highly resistant pathogens for which no effective antibiotics will be available. Clinicians could then be experiencing the same frustrations of not being able to treat infections effectively as were seen in the "pre-antibiotic era."

This is a retrospective study of Streptococcus suis infection in humans submitted to the National Streptococcal Referrence Center of Thailand from 1994 to 2001. There were 11 men and 6 women whose mean age was 46.24 years (range 1 month to 75 years). Among the men, two had known occupational and behavioral exposure to pork or meat products. Among the women, one was a butcher and three were housewives. Half of the patients had underlying diseases. One patient had congenital hydrocephalus, three patients had rheumatic heart disease and three were alcoholics. Two of these patients had a history of skin injury before infection. Nine patients had evidence of acute bacterial meningitis, four patients had infective endocarditis, two had the sepsis syndrome and two suffered from pneumonia and spontaneous bacterial peritonitis. The authors suspected that many cases are not reported particularly where pig-rearing or pork consumption are common. In the absence of an effective vaccine, prevention by public health surveillance is important. Prompt treatment of any cuts and wounds among pork-handlers is a sensible precaution. Furthermore, a high index of suspicion and early detection in order to identify and apply effective antimicrobial agents is necessary to successfully treat S. suis infection.
