cefotaxime and Anemia--Aplastic

Seventy-one patients with severe infections associated with hematologic disorders including leukemia, lymphoma and aplastic anemia were treated with ceftizoxime (CZX) in daily doses of 4-6 g for an average of 20.1 days. Infections associated with hematologic disorders consisted of sepsis and pneumonia, and most of the causative organisms appeared to be Gram-negative bacteria. Of the 64 patients who completed the trial, excellent response was observed in 16 and moderate response in 26. The rate of clinical effectiveness was 65.6%. Side effects observed during the treatment included skin rash in only 1 patient, and hepatic disorders in 6 patients. However, the relationship between CZX and these abnormal findings was not established. These results indicate that CZX is a therapeutically effective and safe antibiotic for the treatment of severe infections associated with hematologic disorders.

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.

Forty patients with leukemia or aplastic anemia were randomized to receive one of the following antibiotic regimens at the onset of fever during granulocytopenia: cefoperazone + amikacin (regimen A), cefoperazone + sisomicin (regimen B), cefotaxime + amikacin (regimen C), cefotaxime + sisomicin (regimen D). All patients were receiving gut decontamination at the time of randomization. Patients were monitored twice weekly with swabs and cultures for bacteria and fungi. Overall, there were 56 febrile episodes: 31 were proven bacterial, 3 were probable, and 16 were of unknown origin. Response rates were comparable in all 4 treatment regimens: 90%, 91%, 92% and 92%, respectively. Three patients died of bacterial infections (2 Gram+, 1 Gram-), one patient died with probable infection, 6 febrile episodes were related to fungal infection (Candida), and 2 patients died. The mortality rate was comparable in all groups. Two patients died of renal failure. Abnormalities in liver function tests were observed, but were without consequences. There were no statistical differences in renal-hepatic toxicity in the 4 arms.

Seventy-five patients with severe infection accompanying hematologic disorder, including leukemia and malignant lymphoma, were treated with cefotaxime (CTX). CTX was administered by intravenous drip infusion at a daily dose ranging from 4 to 16 g for terms of 3 to 21 days. The total doses were ranged from 12 to 226 g. The results obtained were as follows: Clinical effects: Excellent in 20 cases, good in 21 cases, fair in 7 cases and poor in 27 cases. The efficacy rate was 54.7% (41/75). Clinical effectiveness on isolated organisms (27 cases): In single infection (21 cases), the efficacy rates were 80% for Gram-positive cocci, including S. aureus and 63.6% for Gram-negative bacilli other than P. aeruginosa. In mixed infection (6 cases), the rate was 50.0%. There were no significant differences in the efficacy rates for those patients who were grouped by the initial number of neutrophil (less than 100, 101--500 and over 501/mm3). There were no significant difference in the efficacy rates for those patients who were grouped by the initial number of lymphocyte (less than 500 and over 501/mm3). Side effects and abnormal laboratory findings: One case of skin rash and 2 cases of elevated GOT and GPT were observed. CTX was therefore considered as a clinically useful antibiotic for the severe infections even in neutropenic state in patients suffering from malignant hematological diseases.
