[Combined chemotherapy for hemoblastoses and therapy for acute respiratory failure in intensive care conditions].

AIM: To study the efficiency of polychemotherapy (PCT) for hemoblastoses in acute respiratory failure (ARP). SUBJECTS AND METHODS: The case histories of 63 hemoblastosis patients with ARF who received PCT were examined. The patients were divided into 3 groups: 1) 40 patients with acute leukemia (AL); 2) 15 patients with lymphomas; 3) 8 with multiple myeloma (MM). RESULTS: The duration of lung lesion in leukemia was less than that in myeloma and lymphomas (2.5 +/- 5.3 versus 12.8 +/- 30.6 and 21 +/- 10.2 days, respectively). In the patients with leukemia and lymphomas, PCT was initiated earlier than in those with myeloma (1.5 +/- 0.5 versus 1.75 +/- 3.1 and 8.3 +/- 10.9 days, respectively). In 65.1% of the patients, PCT resulted in agranulocytosis, the rate and duration of which did not differ in the groups. APACHE II scores were 23.5 +/- 4.2; PaO2/FiO2 was 182.1 +/- 60.5. The groups did not differ in disease severity. Noninvasive ventilation was made in 22 patients. Artificial ventilation (AV) was used in 39 patients; it was successfully completed in 13 (33.3%) patients. The most common infectious complications were sepsis (60%), septic shock (27%), and bacteremia (16%). Sepsis was encountered twice more frequently in lymphomas and myeloma, and septic shock was 4 times more commonly in leukemias. In myeloma, bacteremia was seen more frequently than in leukemia (50 and 10%; p = 0.024); serum procalcitonin was > 10 ng/ml (100 and 35%); p = 0.028). In leukemias, lymphomas, and myeloma, 28-day survival was 60, 60, and 75%, respectively. The baseline APACHE II disease severity, the degree of hypoxemia, and the presence and duration of agranulocytosis did not determine prognosis. The poor predictors were consciousness impairment, AV, renal failure, and no response to chemotherapy.
