Abstract
BACKGROUND: Antibiotic-associated diarrhea can lead to hypovolemia, which requires intensive care.
AIM: This study aimed to evaluate the effectiveness of parenteral use of alanyl-glutamine as part of combined therapy for treating acute, severe, antibiotic-associated diarrhea in hospitalized patients with cancer.
METHODS: A total of 60 patients (32 men; age range: 58–72 years) were evaluated. The study included patients who developed grade 4 diarrhea (>10 times per day) within 2–8 weeks after receiving antibacterial therapy. The diarrhea was not caused by drug-induced mucositis, and was complicated by dehydration. Patients were randomized into two groups. After the water-electrolyte balance was restored, all patients received total parenteral nutrition. The patients in the study group received additional intravenous alanyl-glutamine at 0.4 g/kg of body weight once daily in days 1 to 14. Enteral nutrition was added when bowel movements decreased to 3–4 times daily. On day 8, total parenteral nutrition was discontinued, and a special diet was prescribed with enteral nutrition for three days. On day 11, enteral nutrition was replaced by probiotic dietary treatment. Laboratory testing included fecal bacteriological tests for Clostridium difficile toxins A and B, and pathogenic intestinal bacteria. The following parameters were assessed at admission and on day 14: severity score using the Acute Physiology and Chronic Health Evaluation II (APACHE II) scale, body mass index, concentrations of total protein, albumin, and electrolytes, liver function tests, azotemia parameters, the duration of diarrhea (defined as ≥4 bowel movements per day), and the recurrence rate over 56 days. A statistical analysis was performed using Microsoft Excel 2011. The results are expressed as the mean ± standard deviation (M ± SD). The two-tailed Student t-test and the Fisher exact test were used to assess statistical differences.
RESULTS: The APACHE II scores at admission did not differ between the study and control groups: 11.2 ± 2.8 vs 10.9 ± 2.3, p > 0.05. The duration of diarrhea was significantly shorter in the study group than in the control group: 3.72 ± 0.48 days vs 6.47 ± 1.14 days, p = 0.03. The recurrence rate in the study group was also significantly lower than in the control group: 6.67% vs 30.0%, p = 0.04.
CONCLUSION: Dipeptide glutamine (alanyl-glutamine) as part of combined intensive care improves the duration and recurrence rate of antibiotic-associated diarrhea in patients with cancer.
