Tigecycline use in cancer patients with serious infections: a report on 110 cases from a single institution.
Tigecycline, the first in a new class of glycylcyclines, has been approved for the treatment of complicated skin and skin structure and intraabdominal infections in adults. However, clinical data on its safety and effectiveness in cancer patients are lacking. We reviewed the records of all cancer patients treated with tigecycline for more than 48 hours between June 2005 and September 2006 at our institution and identified 110 consecutive cases (median age, 58 yr; range, 18-81 yr). We collected data on demographics, cancer type, tigecycline indication, microbiologic characteristics, side effects, and outcome. Sixty-four (58%) patients had hematologic malignancies; 27 patients had undergone hematopoietic stem cell transplantation. Thirty-one (28%) patients had neutropenia, and 62 (56%) were in the intensive care unit at the start of therapy. Most patients (106 [96%]) received tigecycline as a second-line agent (after not responding to other broad-spectrum antibiotics), and 101 (92%) received it in combination with an antipseudomonal drug. The mean duration of therapy was 11 days (range, 3-35 d). Sixty-six (60%) patients received tigecycline for refractory pneumonia, 19 (17%) had bacteremia, 9 (8%) had intraabdominal infections, and 7 (6%) had complicated skin and soft tissue infections. Fifty (45%) patients had microbiologically documented infections, and the remaining patients had negative cultures at the start of therapy.An overall clinical response was noted in 70 (64%) patients. More clinical responses were seen in patients with bacteremia than in those with pneumonia (79% vs. 51%; p = 0.029). Patients with microbiologically documented infections had significantly higher clinical response rates than patients with non-microbiologically documented infections (73% vs. 55%; p = 0.047). Forty (36%) patients did not respond to treatment; 36 of these patients died of active infection during tigecycline therapy. Patients with pneumonia had a significantly higher mortality rate than patients with bacteremia (44% vs. 16%; p = 0.026). During the 60 days of follow-up from the date of clinical response, patients with pneumonia had significantly shorter survival durations than patients with other infections. Of the 42 patients who were not on antiemetics or ventilator support at the start of tigecycline therapy, 2 (5%) experienced mild nausea, and 1 (2%) experienced nausea and vomiting. Only 4 (4%) patients overall experienced diarrhea during tigecycline therapy, all Topics: Adolescent; Adult; Aged; Aged, 80 and over; Anti-Bacterial Agents; Bacteremia; Bacterial Infections; Female; Hematopoietic Stem Cell Transplantation; Humans; Kaplan-Meier Estimate; Leukemia; Lymphoma; Male; Middle Aged; Minocycline; Nausea; Pneumonia, Bacterial; Retrospective Studies; Tigecycline; Treatment Outcome; Vomiting; Young Adult | 2009 |
Elimination of mycoplasma from leukemia-lymphoma cell lines using antibiotics.
Mycoplasmal contamination of cell culture systems continues to present major problems for basic research and for manufacturing of bioproducts. Previous work suggested that certain antibiotics have strong anti-mycoplasma properties and raised the prospect that the technically rather simple antibiotic treatment may be an appropriate means for mycoplasma eradication. We have developed and validated an effective strategy to eliminate mycoplasma from chronically infected cell cultures using antibiotics which have shown strong activity against these contaminants. Here, we describe our experience with the treatment of 123 consecutive mycoplasma-positive leukemia-lymphoma cell lines, comparing five different antibiotic regimens (in total 433 treatments). We optimized the antibiotic dose schedules and the duration of treatments. The various antibiotic treatments which were employed in parallel had a high efficacy, as 71% to 86% of the infected cultures were cleansed. Treatment failure may result from the resistance of the mycoplasmas to antibiotic therapy and the inability of the eukaryotic cells to survive the cytotoxic effects of the antibiotics. Resistance to mycoplasma eradication was observed in 3% to 20% of the cultures. Loss of the cell culture caused by cytotoxicity was seen in 3% to 11% of the treatments. With regard to the overall outcome, 96% of the cell lines were rendered mycoplasma-free with at least one of the antibiotic treatments and were permanently cured. In conclusion, antibiotic treatment represents the most practical and efficient option to cleanse mycoplasma-positive cell lines.

Subcutaneous abscesses caused by Nocardia brasiliensis complicated by malignant lymphoma. A survey of cutaneous nocardiosis reported in Japan.
A 47-year-old Japanese man suffering from T-cell leukemia was examined for multiple subcutaneous abscesses followed to abrasion wound on his right knee. The causative organism was clustered, fine-branched filaments in pus aspirated from the lesions, identified as Nocardia brasiliensis. Most of the lesions regressed from the combined therapy of sulfamethoxazole and trimethoprim, leaving an ulcer on the patient's left leg. The nocardiosis cases in Japan until 1984, including this one, were briefly surveyed.
