The purpose of the present study was to determine whether increased levels of platelet-activating factor (PAF) type activity can be detected in plasma from patients with septicemia and other diseases. A level of PAF below 0.5 ng/mL of plasma was considered normal. We found that plasma from a patient with adverse anaphylactoidic reaction to intravenous analgetics contained 2.1 ng PAF/mL. In seven patients with septicemia, including urosepsis, endocarditis and peritonitis, and with positive blood culture, increased plasma PAF levels (1-20 ng PAF/mL) were observed. Other patients with clinical indications of septicemia had negative blood cultures and/or increased levels of C-reactive protein (CRP). Yet, in the plasma from these patients, no increased PAF levels were detected under the assay conditions used. Two patients with allergic asthma, requiring treatment with steroids, had no measurable plasma PAF. In the plasma from a patient with idiopathic thrombocytopenic purpura (ITP) only an "endogenous" inhibitor of PAF induced platelet aggregation was initially observed. In spite of this, the patient responded to treatment with the PAF antagonist WEB 2086 with a dramatic increase in platelet count (Lohmann et al., Lancet ii, 1147, 1988). Thereafter, also increased PAF levels (3.3 ng PAF/mL) were detected in plasma, although some "endogenous" inhibitor of PAF was still present. In conclusion, increased PAF levels in plasma from patients support a role of PAF in certain human disease states, such as in anaphylactoid reaction, sepsis and septic shock. The type, relevance and specificity of endogenous inhibitors of PAF deserve further study.

Unusual infections associated with colorectal tumors may, in some instances, be the sole clue to the presence of a malignancy. The infections are either related to invasion of tissues or organs in close proximity to the tumor or secondary to distant seeding by transient bacteremia arising from necrotic tumors. Seven patients seen at one hospital over a 5-year period illustrate the clinical presentations of such infections. The infections identified in these seven patients include endocarditis, meningitis, nontraumatic gas gangrene, empyema, hepatic abscesses, retroperitoneal abscess, clostridial sepsis, and colovesical fistulae with urosepsis. A computer-assisted search of the English-language literature and cross-checks from other review articles identified other infections associated with colon cancer, which include nontraumatic crepitant cellulitis, suppurative thyroiditis, pericarditis, appendicitis, pulmonary microabscesses, septic arthritis, and fever of unknown origin. The clinical importance of these infections and their correlation with colorectal malignancies are reviewed.

Starting point of a sepsis with endocarditis which could at last not be controlled chemotherapeutically was a big prostatic utricle cyst. It was hardly accessible for diagnosis, especially X-ray diagnosis. Undoubtedly it is a matter of a rather seldom anomaly although Schuhrke et al. [1] found it in a quarter of their cases with hypospadias. In these cases and especially if a persistent urinary tract infection or a urosepsis exist we have to think of it, as a therapy is possible only operatively.

Group B streptococcal infection has recently been recognised as an important and apparently increasingly common cause of invasive disease in nonpregnant adults. The annual incidence of invasive disease has been estimated at 4.4 per 100,000 nonpregnant adults and is highest among adults over 60 years of age. The most common clinical diagnoses include skin and soft-tissue infections, bacteraemia with no identified source, osteomyelitis, urosepsis and pneumonia. Other important but less common infections include peritonitis, infectious arthritis, meningitis and endocarditis. The majority of adults with group B streptococcal infections have underlying diseases including diabetes mellitus, malignant neoplasms and liver disease. Nosocomial infection and polymicrobial bacteraemia occur in a significant proportion of patients with invasive group B streptococcal disease. Mortality from invasive disease is particularly high in the elderly. For treatment of serious group B streptococcal infections, high doses of benzylpenicillin (penicillin G) are recommended because of the somewhat higher minimal inhibitory concentrations. In addition to parenteral antibiotic therapy surgical management may be required for successful treatment, particularly in the case of soft-tissue or bone infection. Invasive group B streptococcal infection is a major problem in elderly adults and those with chronic diseases, and efforts should be made to identify and treat such infections early. Future approaches may include vaccine prevention of serious group B streptococcal infection in adults at highest risk.

Three cases of serious infection caused by Aerococcus urinae are presented: a patient with endocarditis and two patients with soft-tissue infection (phlegmon and balanitis respectively). The literature on Aerococcus urinae infections is reviewed and the antibiotic therapy discussed. Aerococcus urinae is a pathogen isolated primarily from urine specimens of elderly patients with local or systemic predisposing conditions. Most infections are mild, but serious infections such as endocarditis and septicemia/urosepsis have been described. Penicillin or ampicillin in combination with an aminoglycoside and close monitoring of the patient's clinical status and laboratory results would seem to be the best strategy for management of cases of serious infection.

Nosocomial infection in the critically ill results from defects in the intrinsic barriers to microbial invasion. The diagnosis is complicated by an inability to perform an adequate physical examination in a patient with several compounding findings, usually necessitating sophisticated technologies to aid in the diagnosis. Pneumonia, line sepsis, urosepsis, sinusitis, endocarditis, peritonitis, and acalculous cholecystitis are the more common infections that challenge the care of the critically ill. Antibiotic therapy is adjunctive to efforts to preserve the barrier, but should be started early, should be targeted as specifically as possible to the offending organisms, and should be dosed adequately to ensure an effective concentration in the infected tissue.

Group B streptococcal (GBS) disease in nonpregnant adults is increasing, particularly in elderly persons and those with significant underlying diseases. Diabetes, neurological impairment, and cirrhosis increase risk for invasive GBS disease. Skin, soft-tissue, and osteoarticular infections, pneumonia, and urosepsis are common presentations. Meningitis and endocarditis are less common but associated with serious morbidity and mortality. Disease is frequently nosocomial and may be related to the placement of an iv catheter. Recurrent infection occurs in 4.3% of survivors. Capsular serotypes Ia, III, and V account for the majority of disease in nonpregnant adults. Although group B streptococci are susceptible to penicillin, minimum inhibitory concentrations are 4-fold to 8-fold higher than for group A streptococci. Resistance to erythromycin and clindamycin is increasing. The role of antibodies in protection against GBS disease in nonpregnant adults is unresolved. However, the immunogenicity of GBS vaccines being developed for prevention of neonatal disease should be assessed for adults who are at risk.

An 83-year-old woman was admitted to hospital with complaints of fever, abdominal pain and other complaints suggesting urosepsis. Additional analyses did not reveal the cause of her complaints. After cessation of antibiotic therapy, there was a spontaneous decrease in the infection parameters and she was subsequently discharged. Two and a half months later she was presented in our hospital with low back pain with radiating to the legs. MRI showed signs ofa spondylodiscitis at the level of LIII-LIV existing for some time. Finally, a gram-positive streptococcus infection was found and she was treated with antibiotics for 13 weeks. 6 months later she was free of symptoms. A 57-year-old man was admitted to the intensive care with a double-sided olecranon bursitis and sepsis. An endocarditis caused by Staphylococcus aureus was thought to be the cause of the sepsis and the patient was treated with surgical intervention and antibiotics. Because of persistent sepsis, different CT-scans were performed, and after one and a half months an extensive spondylodiscitis with abscess formation was diagnosed and subsequently treated surgically. A delay in diagnosing spondylodiscitis is the rule rather the exception. The diagnosis should be considered in any patient with localised back pain, especially when accompanied by fever, high ESR, and the presence of risk factors such as high age, diabetes mellitus, immunosuppression, and/or rheumatoid arthritis.

A case of intravenous precipitation of erythromycin is reported along with the patient history, pathologic findings, and a description of the analytical methods and results. The patient was a 75-year-old woman with a history of myocardial infarction, deep venous thrombosis, and diabetes mellitus who underwent aortic valve replacement. She developed endocarditis and recurrent episodes of urosepsis, with multiple organ failure including severe gastric retention, for which she was treated with erythromycin intravenously. She died because of refractory septic shock. Autopsy revealed aortic valve endocarditis, thrombi in the right femoral vein, arterial (nonfungal) thromboemboli in the celiac trunk, and coarse material in the right femoral vein where the tip of the central venous catheter had been located. Microscopical examination of the coarse material showed that it was birefringent crystalline material. Part of the postmortem material was analyzed in the laboratory of the department of clinical pharmacy and revealed the presence of erythromycin. Erythromycin was detected using Fourier transform infrared spectroscopy. An additional specific color test and thin-layer chromatography confirmed this finding. On the basis of the postmortem findings, patient history, and analytical-toxicologic results, we conclude that erythromycin precipitation can occur in vivo after intravenous administration in patients with impaired blood flow.

Escherichia coli is a rare cause of bacterial endocarditis. We report a case of an elderly man with cirrhosis who developed bacterial endocarditis due to E.coli. We review the literature that summarizes a total of 41 cases, with a predominance of elderly women, diabetics, and patients with urinary tract infections and prosthetic heart valves. E.coli bacteremia may be mistakenly attributed to a more benign source such as urosepsis and overlooked as an indication of endocarditis. A delay in diagnosis may lead to higher mortality as the opportunity for early valve replacement in appropriate cases and more prolonged courses of antibiotics may not be considered.
