In order to identify the cause of septicemia and the resistance patterns of bacteria in Swedish patients with hematological disorders, all positive blood cultures collected at a hematological ward during 1980-1986 were evaluated retrospectively. 198 episodes of septicemia in 129 patients were recorded. 54% were males and 46% women with a median age of 67 years (range 16-88). Patients with acute leukemia (46%), lymphoma (19%) and myeloma (19%) dominated. The absolute neutrophil count (ANC) was less than 0.5 x 10(9)/l in 76% of the bacteremic episodes. A total of 253 consecutive isolates were found with 53% Gram-negatives and 47% Gram-positives. The dominating pathogens were Escherichia coli (27%), klebsiella/enterobacter (15%), pseudomonas (7%), coagulase negative staphylococci (13%), alpha-streptococci (13%), Staphylococcus aureus (10%) and anaerobes (6%). Coagulase negative staphylococci showed a significant increase in isolation rate during the study period. The majority of E. coli were resistant to ampicillin. The susceptibility of klebsiella/enterobacter to ceftazidime and cefuroxime was reduced, while no imipenem resistant strains occurred. Among coagulase negative staphylococci 61% were resistant to isoxazolylpenicillin, none to vancomycin. No dramatic changes in the etiology of septicemia or the susceptibility pattern during the study period were noticed. Coagulase negative staphylococci, S. epidermidis in particular, constitute an increasing problem among granulocytopenic patients.

The clinical and diagnostic features of 29 adult patients with H. influenzae septic arthritis are reviewed. Twelve men and 17 women ranging in age from 22 to 82 years developed the infection. H. influenzae septic arthritis is an acute, febrile disease with a mean duration of symptoms before diagnosis of 4 days. Fifteen patients had monoarticular arthritis, 6 with an infected knee. Polyarticular involvement, with a range of 2 to 9 joints, was diagnosed in 14 patients. Nineteen patients had concurrent extraarticular sites of infection, including meningitis, pneumonia, pharyngitis, sinusitis, conjunctivitis, and cellulitis. Twenty-two of 29 patients had predisposing factors for infection, including ethanolism, trauma, rheumatoid arthritis, systemic lupus erythematosus, diabetes mellitus, splenectomy, multiple myeloma, lymphoma, gout, and acquired common variable hypogammaglobulinemia. Characteristic synovial fluid findings included purulent, greenish fluid, elevated WBC count, and gram-negative pleomorphic microorganisms. Treatment for these patients included antibiotic therapy, most often ampicillin and chloramphenicol, and joint drainage by repeated arthrocentesis or arthrotomy. A favorable outcome was reported in 25 of 29 patients. Hemophilus influenzae septic arthritis should be suspected in adults who are immunocompromised and have a concurrent extraarticular source of infection.

The series of 8-aryl-2,6,7,8-tetrahydroimidazo[2,1-c][1,2,4]triazine-3,4-diones (11-20) and 8-aryl-4-imino-2,3,7,8-tetrahydroimidazo[2,1-c][1,2,4]triazin-3(6H)-ones (21-25) were designed and their in vitro cytotoxic activities against human LS180, HeLa, T47D, A549 and RPMI 8226 carcinoma cells are presented. In the crystalline state molecule 12 exists as the predominant tautomeric 3-oxo form, whereas the second possible 3-hydroxy tautomer is not observed. Compound 19 revealed a strong affection to LS180 cancer cells at lower tested concentration (37.9 microM) and simultaneously was found to be non-toxic towards the normal cell line investigated--GMK cells. Furthermore, this compound was proved to possess the efficiency for DNA strand breakage of the examined cancer cell lines. However, imidazotriazin-3,4-dione 20 was able to cause significant viability decreases in human RPMI 8226 peripheral blood myeloma cells. Compound 22 has exhibited remarkable inhibitory effects against LS180 and A549 carcinoma cells, whereas 24 revealed the highest growth inhibition against A549 cell line. Simultaneously, at lower tested concentration these compounds were proved to be completely non-toxic for GMK cells. Moreover, cytotoxic and antibacterial properties of starting, tautomeric 1-aryl-2-hydrazonoimidazolidines (1-6 and 8-9) are presented. Six of them (1-2, 4-6 and 9) proved active as antimicrobials. All these compounds revealed MIC values in the range of 15.0-78.6 microM. Their activities were compared to those of ampicillin and chloramphenicol.

Multiple myeloma is a hematolymphoid malignancy, and patients with this disorder are frequently complicated by infection. An 80-year-old woman with multiple myeloma was complicated by bacterial meningitis, and was admitted to our hospital in August 2007. She initially received ceftriaxone, but culture of cerebrospinal fluid detected Listeria monocytogenes. Ampicillin was administered, but headache and pyrexia persisted for 2 weeks, and on cerebrospinal fluid examination, the proliferation of polymorphonuclear leukocytes had not resolved. After medication with meropenem was started, the clinical symptoms completely disappeared, and the abnormalities on cerebrospinal fluid examination resolved. The patient ultimately received meropenem for 27 days, resulting in a cure. In conclusion, meropenem is useful to treat bacterial meningitis caused by L. monocytogenes. This agent is indicated when ampicillin shows inadequate effect or if the patient has an allergy to ampicillin.

An 87-year-old Caucasian woman with hypertension, diabetes mellitus type 2, and COPD was admitted with 1-week duration of back pain and weight gain. The physical examination revealed jugular venous distention, rales in the left lower lung field, and severe pitting edema over lower extremities. As workup for leukocytosis, blood cultures grew Gemella haemolysans. Subsequently, a transthoracic echocardiogram revealed vegetation on the non-coronary aortic leaflet and mild aortic stenosis. She was treated with ampicillin and gentamicin. After further investigation, the patient was diagnosed with plasma cell myeloma, the monoclonal lambda type. This is the first reported case of G. haemolysans endocarditis in a multiple myeloma patient.
