Sepsis is one of the important complications on the treatment of severe hematological diseases. In this report, we analyzed sepsis in 309 patients with hematological diseases who were admitted to the First Department of Internal Medicine of Yokohama City University Hospital from 1979 to 1986. Positive blood culture were found in 17.8% (55/309 cases) and total positive cases were 73 including recurrent patients. Positive rate by underlying diseases was 30.3% in acute leukemia, 20.8% in
chronic myelocytic leukemia
, 17.2% in aplastic anemia, 8.0% in multiple myeloma, 6.0% in malignant lymphoma and 6.5% in others. The organisms causing sepsis were as follows; gram negative bacilli 56.4%, gram positive organisms 34.6%, fungus 6.4% and anaerobic bacteria 2.6%.
Pseudomonas
aeruginosa was found in 19.2%. The mortality rate of patients with sepsis was 34.2% (25/73 cases). The significant prognostic factors in patients with sepsis were the degree of neutropenia, duration of neutropenia (500 less than microliters), the species of organisms, simultaneous complication with shock and the site of other infections.

We studied the potential value of oral ofloxacin (200 mg twice daily) for selective decontamination and infection prevention in 40 granulocytopenic patients with acute leukemia, blast crisis of
chronic myelogenous leukemia
, hairy cell leukemia or severe aplastic anemia. The quality of selective decontamination was acceptable with rapid elimination of Enterobacteriaceae from the alimentary tract, only a slight decrease in concentrations of anaerobes in faeces, and a small number of newly acquired transient (twelve isolates in seven patients) or colonizing (six strains with 28 isolates in four patients) aerobic gram-negative rods and Staphylococcus aureus (one isolate) recovered from 672 surveillance cultures from faeces, oral washings and urine. Two of three patients colonized with ofloxacin-resistant
Pseudomonas
aeruginosa strains developed
Pseudomonas
infections. A total of twelve acquired infections was observed. Six were microbiologically documented infections, all caused by ofloxacin-resistant bacteria (two P. aeruginosa, two Staphylococcus epidermidis, one Aerococcus viridans, one Micrococcus sp.). Tolerance was acceptable with no serious side effects observed. Mean drug concentrations in serum and saliva were comparable to those determined in healthy volunteers and were found to be higher in saliva than in serum. We conclude that ofloxacin may be studied as an effective alternative to trimethoprim-sulfamethoxazole for selective decontamination and infection prevention in severely granulocytopenic patients. Careful monitoring of colonizing
Pseudomonas
spp. with decreased ofloxacin sensitivity, however, seems necessary.

Infected patients with hematological disorders were treated with the combination of cefmenoxime (CMX) and cefsulodin (CFS). This therapy was done on 74 patients, of whom 38 (51%) had acute myelocytic leukemia, 14 (19%) malignant lymphoma, 7 (9%) acute lymphocytic leukemia, 5 aplastic anemia, 4 adult T cell leukemia, 4
chronic myelocytic leukemia
, 1 multiple myeloma and 1 histiocytic medullary reticulosis. Complicated infections included 5 cases of septicemia, 41 cases of suspected septicemia, 19 cases of respiratory tract infection, 2 with anal abscess, 1 with urinary tract infection and others. The obtained results were as follows: Clinical effectiveness of the combination therapy was excellent in 17 cases (23.0%), good in 24 (32.4%) and poor in 33 (44.6%). Total clinical efficacy rate was 55.4%. Clinical efficacy rate was 40% against septicemias, 51.2% against suspected septicemias and 57.9% against respiratory tract infections. Causative pathogens were isolated in only 21 cases (28.4%): Gram-positive bacteria in 9 cases, Gram-negative bacteria in 11 and fungus in 1. About half of the Gram-negative bacteria belonged to
Pseudomonas
sp. The efficacy rate of this combination therapy against Gram-negative bacterial infections was 72.7% but the rate against Gram-positive bacterial infections were only 33.3%. Only in 1 case, this combination therapy was discontinued because of drug eruption. Abnormal laboratory findings were observed in 5 cases: Elevation of BUN in 3, GOT and GPT in 1 and prolongation of activated partial thromboplastin time in 1. In conclusion, this combination therapy of CMX and CFS is useful and safe against infections complicated by hematological disorders.

Timentin (5.2 g tds) and tobramycin (40 mg tds) were administered to 51 patients (22 male, 29 female, age range 17-72, mean age 40.4) with acute leukaemia,
chronic myeloid leukaemia
in blastic crisis, severe aplastic anaemia and acute agranulocytopenia. All patients had neutropenia (PMN less than 1000/mm3) and fever (greater than 38 degrees C). Febrile episodes consisted of 22 proved septicaemias due to Gram-positive organisms (Staphylococcus aureus, S. epidermidis, enterococcus) in 11 cases and to Gram-negative organisms (Escherichia coli,
Pseudomonas
aeruginosa, Alkaligenes faecalis, Serratia marcescens, Klebsiella pneumoniae) in 10 cases. One patient had a polymicrobial infection (P. aeruginosa, S. aureus, non-haemolytic streptococcus). Twenty-nine infections were diagnosed only clinically. The mean duration of treatment was 11.1 days (range 4-20 days). Eighty-seven per cent of evaluable febrile episodes improved. Among 11 infections due to Gram-positive cocci, eight (72%) resolved, and in nine (90%) of ten cases due to Gram-negative bacilli success was obtained. The polymicrobial infection also resolved. In only four patients were mild side effects seen, e.g. exanthema, pruritus, phlebitis: renal toxicity was not observed. These data suggest that the combination of Timentin and tobramycin is an effective and safe empirical antibiotic regimen in febrile neutropenic patients.

Micronomicin (MCR) at a daily dose of 120 to 360 mg was administered to patients with severe infections who had hematopoietic disorders as underlying diseases. Efficacy and safety of the drug were evaluated. The underlying diseases in the 56 patients included in the evaluation of efficacy were acute myelocytic leukemia (24 cases), acute lymphocytic leukemia (8), acute promyelocytic leukemia (6), acute monomyelocytic leukemia (4), acute monocytic leukemia (1), erythroleukemia (1),
chronic myelocytic leukemia
-blastic crisis (4), malignant lymphoma (3), aplastic anemia (2), and others (3). The infections were septicemia in 9 patients, suspected septicemia in 48, respiratory tract infection in 7, and perianal abscess in 2. The clinical efficacy of MCR was 'excellent' in 12 patients, 'good' in 17, 'fair' in 7, 'poor' in 30 for an efficacy rate of 43.9%. The efficacy rate classified according to infections was 22.2% in septicemia, 56.3% in suspected septicemia. The organisms isolated from the patients with septicemia were Escherichia coli in 2, Klebsiella pneumoniae in 2,
Pseudomonas
aeruginosa in 1, alpha-Streptococcus in 1, Serratia marcescens in 1, and Acinetobacter sp. in 1. The efficacy rate was 15.4% in the 13 patients whose causative organisms were identified. The efficacy rate for patients who had failed to respond to prior antibiotic therapy was 43.9%. The efficacy rate in patients (34 cases) with an initial neutrophil count less than 100/microliter was 44.1%. Side effect which might have been caused by MCR was skin eruption in only one episode among 83 episodes those were evaluated for safety.

During 59 periods of hospitalisation, 39 patients with either acute myeloid leukemia (22), acute lymphatic leukemia (9), acute undifferentiated leukemia (1), blastic crisis of
chronic myeloid leukemia
(6) or high-grade malignant non-Hodgkin lymphoma (1) were subjected to aggressive polychemotherapy after selective decontamination of the gut. The patients were given an amphotericin B suspension in a dosage of 1.2 g/day for two days, after which one tablet of trimethoprim/sulphamethoxazole (TMP/SMZ) (160 mg TMP and 800 mg SMZ) t.i.d. was added to prevent endogenous infections by gram-negative aerobic bacteria or moulds and to maintain the "colonisation resistance" endowed by the anaerobes. During 16 of the 59 periods of hospitalisation, no potentially pathogenic aerobic bacteria were isolated. TMP/SMZ-resistant Escherichia coli were the etiological agent of septicemia in two patients, and resistant Klebsiella pneumoniae and
Pseudomonas
aeruginosa in two other patients. These bacteria were cultured from the patients' fecal samples prior to the development of septicemia. We observed that long-term prophylaxis with TMP/SMZ modified the normal aspect of the fecal biotop culture, not only by suppressing the aerobic gram-negative bacteria, but also by allowing certain clostridia to appear. We differentiated 207 clostridia from the fecal samples of 29 patients and observed a predominance of TMP/SMZ-resistant Clostridium difficile, Clostridium innocuum and Clostridium clostridiiforme. C. difficile was also isolated from the blood culture of a neutropenic patient treated with TMP/SMZ and proved to be very toxic in the Verocell culture.

Ceftezole (CTZ) was administered to 20 patients with hematopoietic malignancy complicated with infections. These patients consisted of 7 cases of AML, 2 ALL, 2 AMMoL, 1 APL, 1 blast crisis of
CML
, 2 HD, and 5 NHL. In 13 cases, sites of infection were determined and causative organisms were identified. In other 7 cases, sites of infection or causative organisms were unknown. In the former 13 cases, pneumonia was demonstrated in 6 patients, tonsillitis in 4 patients, pyelonephritis in 2 patients and sepsis in 1 patient. Klebsiella was separated from 5 patients as the causative organisms, E. coli from 2 patients, E. coli and
Pseudomonas
aeruginosa from 1 patient,
Pseudomonas
cepacia from 1 patient, Streptococcus viridans from 2 patients, Proteus from 1 patient and Torulopsis from 1 patient. Gram-negative rods were separated from 10 of the 13 cases (77%) as the causative organisms. CTZ was administered intravenously in dose from 4 g to 16 g per day combined with other antibiotics (AMK, GM, DKB, TOB, SBPC, CBPC, LC, ST). The response rate in 12 cases of acute leukemia and in 7 cases of malignant lymphoma was 58% and 43%, respectively. Infections occurred in 4 patients with less than 100 neutrophil per mm3 did never favorably responded even with CTZ.

Two hundred eighty-seven episodes of septicemia which occurred in patients with hematological disorders between 1980 and 1993 were examined according to respective underlying diseases. The diagnosis of acute myelogenous leukemia (AML) was made in 155 patients, acute lymphocytic leukemia (ALL) in 45,
chronic myelogenous leukemia
(
CML
) in 29, malignant lymphoma in 36, adult T-cell leukemia (ATL) in 7, multiple myeloma (MM) in 8 and aplastic anemia (AA) in 7. Three hundred and two strains were isolated from 287 patients. Fifty two point three percent of the total isolates were gram-negative bacilli, 26.8% were gram-positive cocci, 17.2% were fungi and 3.6% were anaerobic bacteria. In ALL patients gram-positive cocci accounted for 42.0%. This rate was significantly higher than in other disorder. Additionally, oral mucositis or gingivitis was evaluated as clinical background in 36.1% of ALL cases. Forty-seven point two percent of organisms which caused septicemia in ALL patients were isolated from surveillance cultures of the throat just before the onset of septicemia. These data suggested that in ALL cases microbiological organisms more frequently invaded through injuries of oral mucosa. In ATL,
CML
, MM and AA patients, fungi accounted for more than 25% of causative organisms. The most common organism of all of the strains was
Pseudomonas
aeruginosa (21.9%), but in ATL and MM patients Escherichia coli was more common than P. aeruginosa. At the onset of the septicemia, neutrophil counts were less than 100/mm3 in 76.6% of all patients, and more than 3,000/mm3 in only 5.0%. In contrast to this result, in 66.7% of ATL patients and 37.5% of MM patients, septicemia occurred even when neutrophil counts were more than 3,000/mm3. Septicemia occurred in 28.2% of the total patients but died. The mortality rate in MM and AA patients (50.0% respectively) was higher than in other diseases. According to the mortality of each causative organisms, fungal septicemia had a terribly high mortality of 82.9% while other bacterial mortality was about 20%.

Underlying diseases, pathogenic bacteria, clinical background and outcome were studied during 91 febrile episodes complicated by sepsis in 55 patients with hematological malignancies, who had been admitted to our hospital (Jikei University Kashiwa Hospital) between January 1990 and December 1994. Particularly in patients with P. aeruginosa sepsis, we compared the prophylactic effect of ciprofloxacin (CPFX) alone with that of the combination of polymyxin B (PL-B) plus kanamycin (KM). The major underlying diseases were acute myelocytic leukemia and malignant lymphoma, followed by myelodysplastic syndrome, acute lymphocytic leukemia and
chronic myelocytic leukemia
. Nearly two-thirds of the pathogenic microorganisms isolated were gram-positive bacteria (including coagulase-negative staphylococci and Staphylococcus aureus); approximately one-quarter were gram-negative bacteria (such as
Pseudomonas
aeruginosa), and the remainder were fungi. These microorganisms usually induced sepsis when granulocyte counts were decreased. Sepsis was a direct cause of death in about 60% of the patients and P. aeruginosa sepsis had the worst outcome. Oral administration of CPFX was more effective than PL-B plus KM in preventing P. aeruginosa sepsis. The difference in effectiveness might depend on the absorption profile of the drugs.

In attempt to identify major clinical features of paranasal sinusitis following allogeneic BMT, we reviewed 44 consecutive cases diagnosed at the Hammersmith Hospital between August 1993 and December 1995. All patients had symptoms and signs characteristic of sinusitis. Plain radiographs and/or CT scans revealed fluid levels in 86.4% of patients, opacification in 9.1%, and marked mucosal thickening in 4.5%. Two-thirds of patients were diagnosed within 120 days of BMT. The WBC was less than 1 x 10(9)/1 in 16.3% of patients, the neutrophil count was less than 0.5 x 10(9)/1 in 18.6%, and serum immunoglobulins were depressed (< 6.7 g/l) in 40.6%. Grade III-IV acute GVHD was present in 25.6% of patients and grade I-II in 66.7%; 68.6% developed chronic GVHD. There were 70.5% of patients receiving corticosteroids. Specific pathogens could not be identified in most cases. Pneumonia was present in 10 patients, seven of whom had Aspergillus species identified by bronchoalveolar lavage. Parainfluenza virus was isolated in three patients and
Pseudomonas
aeruginosa in two. Although all patients received antimicrobial therapy, 70.5% developed chronic sinusitis. Fatal complications did not occur. In 94 consecutive patients receiving allografts for
CML
during the period of study, WBC and neutrophil counts were lower 3 months post-BMT in patients who developed sinusitis (P < 0.02). Patients receiving higher doses of total body irradiation (13.2 and 14.4 Gy) had a greater probability of developing sinusitis (P = 0.023). Sinusitis occurred in only one of 37 patients receiving autologous transplants in the same period. Sinusitis is common following allogeneic BMT. Leukopenia is often present, but microbiological diagnosis is difficult, and progression to chronic sinusitis common.
