We analysed the case records of 75 patients with acute myeloid leukaemia treated at our institute from January 1984 to December 1988 to see the pattern and severity of infections and their relationship with granulocytopenia. A total of 184 febrile episodes (mean 2.45) were recorded; 153 (83.15%) were associated with granulocytopenia while 31 (16.84%) were without granulocytopenia. Among granulocytopenic patients, infections could be documented microbiologically in 58.2% and clinically in 30.0% of episodes. In the remaining 41.8% of episodes, no clinical, radiological or microbiological evidence could be found out. The various sites of infection were: septicaemia 21 (13.72%), disseminated fungal infections 4 (2.6%), upper respiratory tract 21 (13.7%), chest 58 (37.9%), gastrointestinal tract 8 (5.2%), genitourinary (7.2%), soft tissues 5 (3.2%) and skin cellulitis 7 (4.6%). Microbiologically, gram negative organisms (Klebsiella pneumoniae, E coli, Pseudomonas aeruginosa) were most common, followed by gram positive (Streptococcal faecalis, Staphylococcus aureus, Staph albus, Staph epidermidis). Four patients had disseminated fungal infection: candida 2, aspergillus *1, mucormycosis *1. Among non neutropenic febrile episodes, the sites infected were: septicemia 2 (6.4%), chest 9(29.0%), upper respiratory tract 1 (3.2%), gastrointestinal 1 (3.2%), soft tissue 1 (3.2%), drug fever 3 (9.6%) and fever of unknown origin 14 (45.2%).

Multiple benefits of intravenous immunoglobulin (IVIG) therapy after marrow transplantation have been reported, including decreased incidence of acute graft-versus-host disease (GVHD), infection, sepsis, cytomegalovirus (CMV) pneumonitis and platelet use. To test the hypothesis that the observed beneficial effects of IVIG are related to the serum IgG levels achieved, we followed IgG levels (pre-infusion, 1 h and 24 h post-infusion) in 45 consecutive marrow transplant recipients. IVIG 500 mg/kg was given weekly for six doses starting day -8 pre-transplant, then every other week for a total of 11 doses. Forty-one patients (22 allogeneic, 17 autologous, two syngeneic) were evaluable. Patients with acute GVHD had significantly lower serum IgG trough levels (less than 1200 mg/dl) noted at day +20 post-transplant and afterwards than patients without GVHD (greater than or equal to 1200 mg/dl). Pharmacokinetic modeling of the data indicates that IgG half-life between day -8 and day +6 may predict which recipients are at increased risk of acute GVHD. Allogeneic recipients in the group with trough levels less than 1200 mg/dl required more platelet transfusions. Although there was no significant difference in fungal infection rates or bacteremia, sepsis was noted in only two recipients (one allogeneic, one autologous), both with serum IgG trough levels less than 1200 mg/dl. In addition, three allogeneic recipients had cytomegalovirus pneumonitis, all in the group with lower IgG trough levels. Thus, while serum IgG trough levels less than 1200 mg/dl appear to be strongly associated with acute GVHD, low levels may also be associated with increased platelet utilization, with cytomegalovirus pneumonitis, and sepsis, but not with the overall incidence of infection.

Seventeen children underwent marrow-ablative high-dose chemotherapy with peripheral blood stem cell autografts and were studied retrospectively to determine the type, frequency, and outcomes associated with infectious complications 3 months postgraft. The patients were kept in isolated rooms with a laminar air flow facility, but no decontamination procedures, such as gut sterilization with nonabsorbable antibiotics, nonmicrobial diet, and skin cleansing, were used. They were under their mothers' daily care to maintain good psychological conditions. After the completion of marrow-ablative chemotherapy and the infusion of stem cells, the absolute granulocyte count exceeded 0.5 x 10(9)/liter with a mean of 17.9 days (range 6-65 days). Fifteen patients developed a total of 16 febrile episodes during the first 4 week period, and the confirmed diagnoses were mucositis (12), enterocolitis (nine), septicemia (four), central venous catheter-associated infection (three), pneumonia (one), perianal abscess (one), and possible invasive fungal infection (one). All episodes were successfully treated with parenteral antibiotic therapy, and no patient died of infectious complications. The observations suggest that high-dose chemotherapy can be performed safely with simple and efficient patient management protocol followed by peripheral blood stem cell autografts.

Sepsis is a major cause of morbidity and mortality in infants with cholestatic jaundice. This may be attributed to altered host defense mechanisms. Fungal infection frequently occurs in immunocompromised patients. This study evaluates the effect of biliary obstruction on blood clearance and organ localization of radiolabeled viable Candida albicans. Male Sprague-Dawley rats (140 to 150 g) were placed in 2 groups. Group I (n = 30) were sham-operated controls. Group II (n = 90) underwent ligation and division of the distal common bile duct (CDL). At 1, 2, and 3 weeks following CDL, 10(7) cells/mL radiolabeled viable C albicans were injected via the tail vein. The final distribution of the organisms was calculated and expressed as the mean percent of radiolabeled organisms per gram and per total organ. Blood clearance of C albicans was similarly rapid in both groups. However, there was a significant decrease in the trapping of fungi by the rat liver Kupffer cells (20.3% +/- 7.9% v control 42.5% +/- 15%; P greater than .001), and increased pulmonary localization of bacteria 3 weeks following CDL (53.6% +/- 13.2% v control 41.4% +/- 6.4%). The significant decrease in liver trapping and increased lung localization of C albicans in CDL rats, may result in systemic reemergence of fungi and play a role in the susceptibility to fungal infection in jaundiced subjects.

Seventy three adults underwent orthotopic liver transplantations between February 1987 and November 1989 and were followed (54 retrospectively and 19 in a prospective study) with the aim of establishing the incidence of deep mycoses (3 disseminated candidiasis due to C. albicans, 1 invasive aspergillosis due to A. fumigatus and 1 invasive pulmonary aspergillosis due to A. niger and A. fumigatus). 4/5 of these infections occurred in the first month after transplantation. All the patients were associated with the following clinical risk factors: previous use of wide spectrum antibiotics (5/5); more than 1 abdominal laparotomy (4/5), due to primary failure of the graft (3/4) and thrombosis of the hepatic artery (1/4). Two of the three patients [corrected] with invasive candidiasis had previous episodes of documented fungemia. 24 patients of the group who didn't show MIP had some risk factor which in all of them was the previous use of high dose steroids and/or of wide spectrum antibiotics, in addition to the used in surgical prophylaxis. In our series, the one risk factor associated with MIP was more than one previous laparotomy (p less than 0.001). Other significant associated infections were 3 bacterial sepsis (2 due to Enterococcus faecalis and 1 due to Staphylococcus epidermidis) and one viral (Cytomegalovirus viremia). The mortality rate was 100%, however the cause of death was multifactorial.

This report reviews the cases of 43 patients with 48 episodes of fungemia, and examines the clinical significance of fungemia and the results of treatment. All episodes were nosocomial infections. Candida albicans (60.4%), Candida parapsilosis (16.7%), and Candida tropicals (14.6%) were the most common fungal pathogens isolated from blood cultures. Patients with Candida albicans had a better survival rate than those with other species (p = 0.011). Polymicrobial fungemia was noted in 5 patients (11.6%). Most patients had underlying diseases and predisposing factors. Intravascular catheters (100%), broad-spectrum antibiotics administration (100%), surgical procedures (46.5%) and total parental alimentation (41.9%) were the most common predisposing factors. The clinical manifestations were not characteristic and consisted of nonspecific signs of sepsis. The overall mortality rate was 79%. We did not find any improvement in the mortality rate of our patients treated with amphotericin B. Early recognization, immediate removal of predisposing factors, and correction of underlying conditions is most important for patients with fungemia. We also suggest that fungal infection should be considered early when a febrile patient at high risk dose not improve with broad-spectrum antibacterial therapy.

Oral complications of cancer therapy often have systemic consequences. Pain and discomfort are common and can lower intake of fluid and nutrients, which in severe cases can lead to dehydration and malnutrition, requiring hospitalization. Oral infections are frequent accompaniments of cancer treatment. Herpes simplex virus is the most common symptomatic oral viral infection, and, in latently infected patients the virus is frequently reactivated after cytoreductive therapy. Viral (infectious) oral mucositis is often indistinguishable from noninfectious mucositis. Bacterial infections are less commonly observed today, perhaps because of the routine use of empiric broad-spectrum antibiotics; however, many episodes of septicemia in neutropenic patients apparently originate from oral microorganisms. Fungal infections are frequent and are usually due to Candida species. Spread to the esophagus or systemic dissemination can occur. Noninfectious oral mucositis can be used as a marker of toxic effects in other organs, especially hepatic veno-occlusive disease. In bone marrow transplant patients with mucositis, hepatic veno-occlusive disease is six times more frequent than in such patients without mucositis.

Since 1984, 47 patients with untreated acute myeloid leukemia (AML) were hospitalized in a special hematology unit for aggressive chemotherapy. Complete remission was obtained in 68%, 15% died of complications of treatment (infections and bleeding) and 15% had refractory leukemia. The actuarial survival after 3 years for patients in remission was 43%. No patients with refractory leukemia lived more than 1 year. The actuarial remission at 3 years of 21 patients who received additional courses of aggressive chemotherapy (consolidation treatment) was 42%, as opposed to 11% in 11 patients who received maintenance treatment. The 47 patients received 108 courses of aggressive chemotherapy including 47 for induction of remission. During 86 courses (80%) the patients developed fever and in 33 blood cultures were positive; during 16 courses a fungal infection developed. The most common bacterial infection was by E. coli. During the first induction treatment 5 patients died of sepsis and 1 of cerebral hemorrhage. None died during consolidation therapy. During the year preceding the opening of the unit, 12 AML patients were treated on regular medical wards, and five (42%) achieved a complete remission, while 6 died of complications during the first course of induction chemotherapy. Our findings are in line with those of similar units, which indicates the importance of special nursing units for the treatment of acute leukemia.

Yeasts may gain entry into the blood via routes such as intubation, intravenous catheterization or by direct persorption from the gut. The latter route becomes important when the numbers of commensal yeasts in the gut exceeds a threshold which may vary between animal species. In a prospective study utilizing serial, twice weekly quantitative stool cultures during the first 6 weeks of life of 40 very low birth weight infants, we found a threshold of 8 x 10(6) Candida colony-forming units/gram of stool. Beyond this threshold 50% of the infants developed gastrointestinal symptoms and 28.5% developed systemic sepsis within 1 to 3 weeks of heavy colonization. The gastrointestinal colonization rate was 62.5% (25/40) with 66% having Candida colony-forming units greater than 8 x 10(6)/g stool.
