RESUMO
INTRODUCTION: During the administration of antineoplastic drugs, acute complications because of toxicity occur, determining their hospital readmission, visits to the emergency department, use of antimicrobials, and possibilities of presenting systemic infections, impacting on their life quality. METHODS: Through a prospective cohort, 60 children with acute lymphoblastic leukemia were followed-up for 30 days after the hospital discharge because of chemotherapy administration, those patients were previously included in a single-blinded study in which 30 (group 1) received Lactobacillus rhamnosus GG probiotic during the administration of chemotherapy. The remaining 30 patients did not receive probiotics (group 2). There were evaluated gastrointestinal symptoms, such as diarrhea, dyspepsia, abdominal distension, meteorism, constipation, nausea, and vomit, development of infections, antibiotic use, number of emergency department visits, number of hospitalizations, and sepsis diagnosis. STATISTICAL ANALYSIS: To assess the impact of the use of probiotics, the difference in proportions between both study groups was evaluated. RESULTS: Gastrointestinal manifestations (nausea, vomiting, diarrhea, constipation) occurred in 30% of patients in group 1 versus 63% of group 2 (P=0.009). Nine of 30 patients (30.0%) in group 1 went to the emergency room, versus 33.3% of group 2 (P=0.7). Antimicrobials were used in 8 subjects (26.6%) in group 1 versus 6 subjects (53.3%) in group 2 (P=0.03) suspected of an infectious disease. Four (13.3%) group 1 patients were hospitalized versus 30% of group 2 (P=0.1). Two subjects (6.6%) in group 1 had sepsis versus 7 (23.3%) in group 2 (P=0.07).Conclusions:The results indicate that the use of probiotics can be a great alternative in the improvement of gastrointestinal symptoms and the adverse effects associated with chemotherapy.
