[Lung biopsy in the diagnosis of causes of lung involvement in hemoblastosis].

AIM: To ascertain the role of lung biopsy in diagnosis of lung lesions in hemoblastosis (HB) patients. MATERIAL AND METHODS: The results of diagnostic biopsies of the lungs obtained from 22 HB patients are presented. Ten patients had no respiratory insufficiency (RI), twelve patients had RI. The biopsy was transbronchial in 1 case, thoracoscopic in 10 and open in 11 cases. RESULTS: In RI-free patients lung biopsy was informative in all the cases. The biopsy provided information which allowed therapy modification resulting in improvement of the patient condition. In RI patients biopsy was informative in 8 of 12 patients. Nonspecific changes in the lungs were identified histologically in 2 of 12 patients. In 2 RI patients lung biopsy confirmed the diagnosis made after examination of the bronchoalveolar lavage. Modification of therapy after the biopsy was conducted in 58.3% HB patients with RI. Improvement was seen in 2 of them. 10 of 12 patients with RI died within 1-2 weeks after biopsy. CONCLUSION: Lung biopsy in HB patients should be obtained only after examination with noninvasive methods and before development of RI as prognosis after lung biopsy in the presence of RI is unfavourable. The histological material should be examined for all expected pathogens.

[Diagnosis of pulmonary lesions in acute respiratory insufficiency in patients with depressed hemopoiesis].

AIM: To analyse causes of acute respiratory failure (ARF) and methods of diagnosis of pulmonary lesions in patients with depressed hemopoiesis (DH). MATERIAL AND METHODS: 50 patients with DH and ARF were examined according to the protocol including x-ray, computed tomography, fibrobronchoscopy with bronchoalveolar lavage, cytological, bacteriological, virusological studies of the lavage fluid, biopsy of the lung. The algorithm of the protocol is provided. RESULTS: Sensitivity of the lavage fluid in diagnosis of fungal, bacterial, pneumocystic and cytomegaloviral infections was 84, 78, 93 and 93%, respectively. The cytologic examination of the lavage fluid may detect lung infiltration with blood tumors. In complicated diagnostic cases lung biopsy verified pulmonary lesion but its conduction aggravated the patients' condition. ARF patients with DH, bacterial flora, fungi, cytomegalovirus and pneumocystic infection, pulmonary tumor involvement, pulmonary lesions in ATRA-syndrome, non-infectious lesions of the lungs after bone marrow transplantation were found in 38, 18, 40, 18, 8 and 4% of cases, respectively. CONCLUSION: DH patients with ARF should be examined by the protocol including both non-invasive and invasive diagnostic methods. Accurate diagnosis of ARF causes is the basic reserve in the treatment of such patients.

[Tumor necrosis factor, interleukin-6, endotoxin and procalcitonin in septic shock in patients with hematologic neoplasms].

AIM: To study changes in proinflammatory markers and mediators in septic shock in patients with hematologic malignancy (HM). MATERIAL AND METHODS: The examination of 33 patients with HM and septic shock included measurement of plasma concentrations of tumor necrosis factor (TNF), interleukine-6 (IL-6), endotoxin, procalcitonin (PCT) 12-24 hours before and each 12 hours after shock; registration of central hemodynamics parameters, the condition severity by APACHE II. RESULTS: Out of 33 patients 18 died of refractory shock, 15 survived the shock. Within the first shock hour TNF fell from 571.2 +/- 195 to 115.8 +/- 71.1 pg/ml (p < 0.02), later being stable. In those who died and survived TNF was the same. IL-6 fall was seen 36 hours after shock and was observed in the survivors; in those who died IL-6 was unchanged. Endotoxin in the blood was detected in 21 of 33 patients. In the survivors endotoxinemia declined after 2 days of treatment. 72 hours after beginning of the shock the survivors had no endotoxin. In shock APACH II severity of the patient's condition was graver in patients with endotoxinemia than without it (31.6 +/- 1.6 and 28.1 +/- 1.6 scores, p < 0.05). Blood endotoxin levels and APACHE II scores correlated (r = 0.24, p < 0.05) positively and negatively with deficiency of buffer bases (r = -0.29, p < 0.05) and blood pH) r = -0.3, p < 0.05), left ventricular contractility index (r = -0.46, p < 0.01) and right ventricle (r = -0.52, p < 0.01), mean AP (r = -0.22, p < 0.03). PCT concentration was lower before shock than on its hour 1 (4.2 +/- 2.9 and 6.9 +/- 1.1 ng/ml, p < 0.05). No significant changes in PCT were found later. CONCLUSION: PCT is a specific marker of a severe infection. Rapid elimination from the blood of TNF and IL-6 makes them inadequate in sepsis diagnosis. Endotoxinemia aggravates the patients condition. Positive LAL-test results were obtained in gram-negative and fungal infections.

[Plasmapheresis in combine therapy of hypercoagulation syndrome in hematogenic thrombophilia].

AIM: To specify indications to plasmapheresis (PA) and to assess its efficiency in patients with hypercoagulatory syndrome in hematogenic thrombophilia (HT). MATERIAL AND METHODS: 18 patients (11 males, 7 females, age 26-50 years) with various forms of HT received standard antiaggregation, anticoagulatory therapy plus therapeutic PA. By PA technique the patients were divided into two groups. RESULTS: A positive trend in clinical, instrumental and laboratory indices was observed in all the patients. CONCLUSION: Therapeutic PA in hypercoagulation syndrome in HT patients leads to fast normalization of the clinical picture and reestablishment of patency of thrombus-affected vessels.

[Clinical manifestations, diagnosis and course of Pneumocystis carinii pneumonia in patients with hematologic diseases].

AIM: To characterize clinical, diagnostic and course features of pneumonia caused by Pneumocystis carinii (PC) in hematologic inpatients. MATERIALS AND METHODS: 27 patients with blood diseases were studied. 22 of them had acute respiratory insufficiency and 5 had unclear lung affection. The data from bronchoalveolar lavage (BAL), lung biopsy, serum tests for IgG, IgM anti-PC-antibodies were used for diagnosis of PC-pneumonia. RESULTS: PC-pneumonia was diagnosed in 8 of 27 patients. Clinical manifestations characteristic for PC-pneumonia were not found. In 5 patients the diagnosis was made on the evidence provided by BAL. Lymphocyte count in BAL was elevated to 27.7 +/- 8.7%. Open biopsy of the lung and transbronchial biopsy diagnosed PC-pneumonia in 2 and 1 patients, respectively. Previous BAL examinations failed to detect PC-pneumonia in 2 of them. In all the patients PC-pneumonia was associated with another infection (bacterial, cytomegaloviral). Histologically, the picture of the disease was determined by the severity of the lung affection or its complications. 5 of 8 patients failed treatment with trimethoprim-sulphamethoxazole and died. Marked respiratory insufficiency was registered at PC-pneumonia diagnosis in all the lethal cases. CONCLUSION: Clinical and x-ray pictures of PC-pneumonia in hemoblastosis patients are not specific. All such patients with symptoms of lung infection resistant to antibacterial and antifungal therapy should be examined for PC-pneumonia.

[The efficacy of artificial pulmonary ventilation in acute respiratory failure in patients with hemoblastoses].

The authors review pulmonary effects achieved for 3 years in hemoblastosis patients subjected to artificial lung ventilation (ALV). Out of 44 patients treated the response to ALV was obtained in 7 (16%). Prior to ALV, two of them had granulocyte count under 0.5 x 10(-9)/1. ALV was discontinued in them after recovery of normal granulocyte count. Three patients (7%) survived 6 months and longer. Problems of differential diagnosis in different variants of acute respiratory failure in hemoblastosis patients and ALV potentialities are discussed.
