OBJECTIVE: To analyze the risk factors affecting the chemotherapy-related infections in patients with acute lympho-blastic leukemia (ALL).
METHODS: The clinical data of 102 patients with ALL from January 2014 to December 2018 were collected and retrospectively studies. The risk factors of chemotherapy-related infections were analyzed by univa-riate and multivariate logistic regression.
RESULTS: A total of 386 courses of chemotherapy were completed, out of which the infection occurred in 201 course, with the infection rate of 52.07%, identified infection number was 215 case-times, including perianal infection of 13.95% (30/215), oral infection of 13.49% (29/215), blood flow infection of 1721% (37/215), lower respiratory tract infection of 37.21% (80/215), urinary infection of 3.26% (7/215), skin infection of 3.72% (8/215), digestive and intra abdominal infection of 9.30% (20/215), and other infections of 1.86 (4/215). Totally 88 strains of pathogenic bacteria were detected, including 29 Gram-positive bacteria (32.95%), 52 Gram-negative bacteria (59.09%) and 7 fungi (7.95%). Gram-positive bacteria mainly were Staphylococcus haemolyticus and Enterococcus faecium, susceptible to tegacycline, vancomycin and linezolid; Gram-negative bacteria mainly were Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae, susceptible to tegacycline, amikacin, piperacillin/tazobactam and imipenem; Candida was the dominant fungus. Living in an ordinart ward, neutrophil defi-ciency for more than 7 days after chemotherapy and incomplete remission were independent risk factors of related infections during the induction chemotherapy in ALL inpatients, and hospitalization time also closely related with chemo-therapy-related infections in ALL inpatients (P<0.05). Neutrophil deficiency for more than 7 days after chemotherapy was an independent risk factor of chemotherapy-related infections in ALL inpatients in the consolidation chemotherapy (P<0.05).
CONCLUSION: Patients with ALL are prone to chemotherapeutic-related infections, and those who lack neutrophils for more than 7 days after chemotherapy and who do not reach complete remission are more prone to infection. Living in laminar flow ward and reducing hospitalization stay can help reduce the incidence of infection.
