Thirty-four patients received bone marrow transplants from unrelated donors. Donors and recipients were phenotypically matched for 6 of 6 HLA-A, B, and DR antigens in 27 cases and at 5 of 6 antigens in 7 cases. Twenty-three patients had leukemia, six had myelodysplasia, and five had aplastic anemia. Twenty-four patients had durable engraftment. Five died of sepsis prior to engraftment. Five patients failed to engraft; 2 of these patients had autologous bone marrow recovery. Seventeen patients developed grade greater than or equal to II acute graft-versus-host disease for an actuarial probability of 67 +/- 20%. The severity of acute graft-versus-host disease and its mortality appeared increased for recipients matched for 5 of 6 HLA-A, B, and DR antigens. Of the 34 patients, 13 (38%) are alive; actuarial survival beyond 6 months is 44 +/- 17%. None of the 25 leukemia and myelodysplasia patients achieving engraftment have relapsed. For leukemia and myelodysplasia recipients of 6 of 6 HLA-matched grafts, actuarial survival at 6 months was 55 +/- 21% compared with 14 +/- 26% for recipients matched for 5 of 6 HLA loci (P = 0.19). Infection and acute graft-versus-host disease were the primary causes of death in the engrafted patients. Survival for aplastic anemia patients was 20%. Late deaths due to pneumonia and bronchiolitis obliterans occurred after one year in 2 patients. Closely matched unrelated donor bone marrow transplants are associated with a higher incidence of graft failure and graft-versus-host disease than typically reported for transplants from HLA-identical siblings, but these preliminary data suggest a lower rate of relapse.

Infections due to Gram-positive bacteria, especially coagulase-negative staphylococci, have been increasing in immunocompromised patients during the last 5 years because of an increased use of Hickman catheters and oral gut decontamination with quinolones. Teicoplanin, a new glycopeptide antibiotic, has a long plasma half-life which allows once-a-day bolus administration, making it a 'user friendly' agent. A randomized comparative evaluation of teicoplanin plus aztreonam versus gentamicin plus piperacillin in leukaemic patients with a clinical diagnosis of septicaemia was undertaken. The objectives of this study were (1) to evaluate the efficacy and safety of teicoplanin and aztreonam in comparison to a 'standard antibiotic' regimen and (2) to assess the local and systemic tolerance of these drugs. Results of the study in more than 70 patients to date are presented, and the role of anti-Gram-positive antibiotics in the management of severe sepsis in immunocompromised patients is discussed.

The long-term CVC allows patients with a variety of diseases to lead a more normal and pain-free life. The use of these catheters has become commonplace in most hospitals, and the physician caring for patients in the ICU will be caring for increasing numbers of patients with an indwelling long-term CVC. Infections of these catheters can be manifested in many different ways: tunnel infections, exit site infections, catheter-related bacteremia, and septic thrombophlebitis. The overwhelming majority of these infections are caused by coagulase-negative staphylococci, but physicians should be aware of the wide variety of organisms that can infect the long-term CVC. The diagnosis of long-term CVC sepsis can be difficult, but the use of quantitative blood cultures for catheters left in place and the Maki method for culturing those catheters that are removed will aid physicians in their quest for diagnostic certainty. The great majority of catheter infections will resolve with antibiotic therapy alone without the need for catheter removal, but there are important exceptions to this general rule. Tunnel infections and fungal long-term CVC infections often require catheter removal for their resolution; septic thrombophlebitis and CR-SCVT require the addition of anticoagulation or fibrinolytic therapy to antibiotic regimens for resolution of the infection, and surgical debridement may be warranted if these modalities fail to resolve the infection.

This study showed several accumulated data through ten years from our experience in hematopoietic disorders and associated infections, which has been analyzed by the Hanshin Study Group of Hematopoietic Disorders and Infections. Since 1979 to 1988, our group had evaluated the sorts of causative organisms and the efficacy of various antibiotics therapy in 2119 cases of infectious diseases associated with hematopoietic disorders. On behalf of evaluating the changes of disease profile for ten years, we divided the accumulated data into three phases; former phase the first three years, middle phase the second three years and late phase the last four years. There was no significant difference in the frequency of various hematopoietic disorders among the three phases. Each leukemia patients occupied 77% of all cases. Sepsis suspected is the most frequent infectious disease accounting for 68.8%. The other infectious diseases were 8.4% of the sepsis, 14.8% of the respiratory infections and 3.1% of the urinary tract infections. Comparing the frequency of infections among the three phases, the respiratory and urinary tract infections inclined to decrease. Of the 532 strains isolated from 2119 cases and identified as causative organisms, gram-negative bacilli occupied 62.8% and gram-positive bacteria 36.5%. In comparing the percentage of gram-negative bacilli among the three phases, it showed a decreasing tendency in order former phase 63.6%, middle phase 76.4% and late phase 43.8%. Pseudomonas, however, had been isolated at almost constant ratio through ten years. On the other hand, the ratio of gram-positive bacteria isolated were 34.5% in former phase, 23.6% in middle phase and 56.3% in late phase, showing increasing a tendency through the period. Twenty-three kinds of antibiotics were administered by intravenous drip infusion. The efficacy rate was 43.9% to 67.2%. In particular, effectiveness of antibiotic therapy often depends on the change of peripheral neutrophil counts from the onset and during the therapy. The efficacy rate, however, was 36% even neutrophil counts have not shown the tendency of increase from less than 100/microliters.

Infection is a potentially life-threatening complication of central venous catheterization. Although line-related bacteremias and sepsis are relatively uncommon, the frequent use of central lines in the intensive-care unit makes these infections a common consideration. Semiquantitative culture techniques for analysis of the catheter tip provide evidence for the diagnosis of catheter-related infections. Bacterial growth of more than 15 colony-forming units/plate is typically considered significant. Preventive measures include using sterile insertion techniques, providing meticulous care for the local site, and minimizing the duration of catheter use. The practice of changing lines over a guidewire is controversial. For treatment of most catheter-related infections, the catheter should be removed and antibiotics should be administered if associated systemic infection occurs.

Between January and December 1988, 383 neonates were admitted to our neonatal intensive care unit. 1,991 swabs and blood cultures were tested bacteriologically. Among them 90 specimens obtained from 41 patients were positive for Acinetobacter calcoaceticus. During this period we discovered and treated three cases with A. calcoaceticus sepsis. Three additional cases had blood cultures positive for this bacterium without demonstrating any clinical signs of infection. There is good evidence that contaminated warm air humidifiers were the source of infection. A review of microbiological data for several months preceding the outbreak showed a definite increase in the presence of A. calcoaceticus. The affected neonates required specific antibiotic therapy and intensive care. All of them survived. Conditions favoring the spread of these generally non-pathogenic bacteria and modes of preventive measures are discussed. The necessity of continuous bacteriological surveillance and careful disinfection of intensive care equipment is emphasized.

The new fluoroquinolones have not been tested in children despite their wide spectrum of in vitro activity and efficacy, because of an observed damage to cartilage in young animals. However, in some cases they may be life-saving. We present three pediatric patients with life threatening infections in whom the fluoroquinolones were used when other antibiotics failed: A seven-year-old boy with meningitis due to multiresistant Acinetobacter calcoaceticus, a three-year-old boy with Job's syndrome with line sepsis due to Staphylococcus epidermidis and a four month-old boy with agammaglobulinemia with mixed infection due to Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter spp. All three children were cured of their infections.

To compare the effectiveness of cystgastrostomy and cystjejunostomy for treatment of pancreatic pseudocysts, 39 patients with cystgastrostomy were compared to 59 patients with cystjejunostomy. The groups were comparable in age, sex, cause of pancreatitis, pseudocyst location, symptoms, and preoperative serum amylase level. Cysts treated with cystgastrostomy were larger (mean diameter, 11.1 +/- 0.9 cm) than cysts treated by cystjejunostomy (mean diameter, 6.7 +/- 0.7 cm) (p less than 0.05). Mean duration of surgery was 148 +/- 11 minutes for cystgastrostomy versus 265 +/- 15 minutes for cystjejunostomy (p less than 0.05). Mean blood loss was 397 +/- 82 ml for cystgastrostomy versus 703 +/- 80 ml for cystjejunostomy (p less than 0.05) Mean intraoperative fluid requirements were 2640 +/- 313 ml for cystgastrostomy and 4403 +/- 362 ml for cystjejunostomy (p less than 0.05). Cyst recurrence was 10% for cystgastrostomy versus 7% for cystgastrostomy. Postoperative gastrointestinal bleeding occurred in 8% of patients with cystgastrostomy and in 2% of patients with cystjejunostomy. Infection problems with cystjejunostomy included two wound infections and one case of septicemia; infection problems with cystjejunostomy included five intraabdominal abscesses, two wound infections, and one case of pneumonia. Two patients died with cystgastrostomy (both from gastrointestinal bleeding); two patients died with cystjejunostomy (one from intraabdominal sepsis and one from pulmonary embolus). Cystgastrostomy was used for significantly larger pseudocysts and was associated with significantly less blood loss and operating time than cystjejunostomy (p less than 0.05). Morbidity and mortality from cystgastrostomy and cystjejunostomy were comparable, although gastrointestinal bleeding was more common with cystgastrostomy and intraabdominal abscess was more common with cystjejunostomy. Since cystgastrostomy can usually be performed more quickly and with less blood loss, it should be considered whenever anatomically feasible.

Infections in burn patients continue to be the primary source of morbidity and mortality. Topical antimicrobial therapy remains the single most important component of wound care in hospitalised burn patients. The goal of prophylactic topical antimicrobial therapy is to control microbial colonisation and prevent burn wound infection. In selected clinical circumstances topical agents may be used to treat incipient or early burn wound infections. At the present time silver sulfadiazine is the most frequently used topical prophylactic agent; it is relatively inexpensive, easy to apply, well tolerated by patients, and has good activity against most burn pathogens. In patients with large burns the addition of cerium nitrate to silver sulfadiazine may improve bacterial control. Mafenide acetate has superior eschar-penetrating characteristics, making it the agent of choice for early treatment of burn wound sepsis. However, the duration and area of mafenide application must be limited because of systemic toxicity associated with prolonged or extensive use. Other agents, such as nitrofurazone or chlorhexidine preparations, may be useful in isolated clinical situations. The undesirable side effects of silver nitrate solution limit its use by most clinicians at the present time.

Infection remains a major cause of morbidity and mortality in intensive care medicine. The increased susceptibility of the severely injured patient to sepsis and consecutive multiorgan failure has been attributed to abnormalities in cell-mediated immunity. The purpose of our study was to determine changes in the pattern of lymphocyte subpopulations in severely injured patients and to relate these changes to any development of sepsis and to outcome (indirect immunofluorescence with monoclonal antibodies). During 14 months we investigated 28 patients (ages 15-65 years) suffering from severe multisystem trauma (22 cases) or diffuse peritonitis (6 cases), 6 of whom (21.4%) developed sepsis and multiorgan failure; 4 of these 6 septic patients died. According to the clinical data, patients developed sepsis between the 3rd and 6th days after trauma. We therefore defined days 1-3 as the preseptic phase, days 3-6 as the phase of sepsis development, and days 4-10 as the phase of septic disease. In the preseptic phase there was no statistically significant difference in the pattern of the eight lymphocyte subpopulations measured between patients who later developed sepsis and those who did not. During the phase of sepsis development, however, the patients who did develop sepsis showed significantly reduced numbers of CD2-, CD8-, and CD20-positive cells (P = 0.0003; P = 0.009; P = 0.012). The number of helper cells (CD4) was also decreased, but the difference between the two groups failed to reach statistical significance (P = 0.08).(ABSTRACT TRUNCATED AT 250 WORDS)
