[The attitude of patients with types 1 and 2 diabetes mellitus towards having the disease]. / Otnoshenie k bolezni patsientov s sakharnym diabetom 1-go i 2-go tipov.

AIM: To analyze the types of attitude towards disease, their relationships to its course in patients with diabetes mellitus (DM). SUBJECTS AND METHODS: 418 patients with DM, including 318 with type 2 DM (T2DM) and 100 with Type 1 (T1DM), were examined. Clinical and laboratory examinations were performed; the types of attitude towards the disease were studied. RESULTS: The patients with T2DM were more frequently found to have anxious (12.9%) and hypochondriacal (10.7%) types of attitude towards the disease; those with T1DM had euphoric types. The paranoiac type of disease attitude, which was characterized by the presence of peculiar notions about the disease, was detected in 15.1% of the patients with T2DM and in 13% of those with T1DM. Hypernosognosia (overreaction to disease) was more often identified in T2DM (62.3% versus 39% in T1DM (χ2; p < 0.001). In the T2DM group, hypernosognosia was more frequently seen in women, unemployed persons, and obese patients. With the comparable awareness about the disease and degree of self-control, the patients with T2DM with no signs of hypernosognosia had a lower glycated hemoglobin level [7.35 (6.6; 8.6)%] than those with hypernosognosia [7.9 (7; 9.4)%] (p = 0.024). CONCLUSION: The revealed peculiarities of attitude towards the disease in patients with DM justify the need for increased attention to their psychological characteristics. The situation could be improved if the physicians are be informed, the time of outpatient care is prolonged, and psychotherapists and/or clinical psychologists are widely involved in the management of diabetic patients.

[Adult B-cell acute lymphoblastic leukemias: Conclusions of the Russian prospective multicenter study ALL-2009]. / Ostrye V-limfoblastnye leikozy vzroslykh: vyvody iz Rossiiskogo prospektivnogo mnogotsentrovogo issledovaniia OLL-2009.

AIM: To analyze the efficiency and reproducibility of the ALL-2009 protocol within the Russian prospective multicenter study based on different principles of cytostatic effects (non-intensive, but continuous cytotoxic treatment and a small number of allogeneic hematopoietic stem cells). SUBJECTS AND METHODS: The ALL-2009 (NCT01193933) study conducted in April 2009 to December 2016 included 194 patients (95 males and 99 females) aged 15 to 55 years (median age 28 years) with Ph-negative B-cell acute lymphoblastic leukemia (ALL). There was early pre-B-cell ALL in 54 patients, common ALL in 101, pre-B ALL in 39, initial leukocytosis in 9.4·109/l (0.4-899.0), lactate dehydrogenase in 901 IU (31-13 059), an initial central nervous system lesion in 17 (8.7%), mediastinal injury in 3 (1.5%), and splenomegaly in 111 (57.2%). The results of standard cytogenetic analysis are known in 113 (60.4%) patients. Normal karyotypes were detected in 49 (54.5%) out of the patients; t(4;11) in 9 (5.4%), t(1;19) in 2 (1.2%), and other karyotypic abnormalities in 53 (46.9%). Thirteen (7.8%) patients underwent allogeneic hematopoietic stem cell transplantation in first complete remission (CR); their proportion did not differ in the federal and regional centers. RESULTS: The frequency of CR achievement was the same in the federal and regional centers and generally amounted to 87.5%. Early (8.8%) and CR (9.6%) mortality rates remained high despite the low aggressiveness of cytotoxic action, necessitating the improvement of auxiliary treatment. The five-year overall survival (OS) rates vary considerably in the federal and regional centers (72.6 and 43.8%), the relapse-free survival (RFS) (70.2 and 53.4%) and recurrence risk (23.1 and 36.5%) are comparable. This suggests that the non-intensive, but continuous exposure principle built in the ALL-2009 protocol makes it possible to reproduce the envisaged treatment program and to achieve satisfactory results. CONCLUSION: The ALL-2009 protocol allows both the federal and regional centers to obtain the long-term results comparable with those of current foreign studies: OS (54.2%), RFS (56.5%); and relapse risk (35.4%). Multivariate analysis has identified age (over 30 years), initial leukocytosis (30·109/l and more) and t(4;11) among the main clinical prognostic factors. Gene mutation detection evaluated in a small number of patients (8/36) is not a poor prognostic sign. There is a need for further investigations with centralized evaluation of the mutation status of leukemic cells and the clearance of minimal residual disease.

[Acute Ph-negative lymphoblastic leukemias in adults: Risk factors in the use of the ALL-2009 protocol]. / Ostrye Ph-negativnye limfoblastnye leikozy vzroslykh: faktory riska pri ispol'zovanii protokola OLL-2009.

AIM: to analyze well-known risk factors (RFs), such as age, immunophenotype, baseline leukocytosis, enhanced lactate dehydrogenase (LDH) activity, time to achieve complete remission, a risk group, and cytogenetic abnormalities) in patients with acute lymphoblastic leukemia (ALL) in the use of the ALL-2009 protocol. SUBJECTS AND METHODS: The protocol covered 298 patients (137 women (including 13 pregnant women) and 161 men) aged 15 to 55 years (median age 28 years) with Ph-negative ALL. The phenotype was unknown in 6 patients. Three (1%) were ascertained to have a biphenotypic variant. 182 (62.4%) patients were found to have B-cell ALL (early pre-B ALL (n=51); common ALL (n=92), and pre-B ALL (n=39); 107 (36.6%) patients had T-cell ALL (early T-ALL (n=56); thymic T-ALL (n=41), and mature T-ALL (n=10). According to the baseline clinical and laboratory parameters (leukocytosis of 30·109/l and more for B-ALL; and that of 100·109/l and more for T-ALL; phenotype В-I for B-ALL, phenotype Т-I-II-IV for T-ALL; LDH activity was more than twice the normal values; the presence of translocation t(4;11)), the high-risk group included most patients with B-ALL (n=110 (72.8%)) and T-ALL (n=76 (76%)). Thirty-five patients with T-ALL underwent autologous bone marrow transplantation (BMT). Allogeneic BMT was performed in 18 (7%) of the 258 patients who had undergone an induction phase. RESULTS: Five-year overall survival for all the patients included in the investigation was 59%; relapse-free survival was 65%, which was significantly different in the patients with B-ALL and in those with T-ALL: the overall survival rates were 53.3 and 67.5% (p=0.1); the relapse-free survival was 56 and 79% (p=0.005), respectively. Multivariate analysis including the well-known RFs demonstrated that the latter for T-ALL were of no independent prognostic value and only the patient's age was identified for B-ALL (p=0.013). CONCLUSION: A lower chemotherapeutic load and a small number of allogeneic BMTs did not affect total positive treatment results in adult patients with ALL, by complying with the principle achieving the continuity of cytostatic effects and by preserving the total cytostatic loading dose. The results of the Russian investigation casts some doubt on the necessity of using very intensive consolidation cycles and performing a large number of allogeneic BMTs in adult patients with ALL.

Role of Interleukin-10 Gene Promoter Region Polymorphism in the Development of Chronic Lymphoid Leukemia.

Relationship between interleukin-10 (IL-10) gene G-1082A (rs1800896) polymorphism and the risk of development and stages of chronic lymphoid leukemia is studied in ethnic Russian residents of the Kirov region of Russia. Associations of allele -1082A and genotypes (-1082AA/-1082AG) with the risk of chronic lymphoid leukemia are detected (OR=1.39, 95%CI=1.09-1.78 and OR=1.66, 95%CI=1.09-2.54, respectively). In addition, association of 1082AA genotype with late stages of the disease by the moment of diagnosis is detected. These data indicate that IL-10 polymorphism G-1082A may be involved in the pathogenesis of chronic lymphoid leukemia.

[The diagnostic of defects of inborn immunity under B-cell tumors of lymphatic system].

The genetic characteristics are key risk factors of development of many human neoplasms including B-cell tumors of lymphatic system. The relationship between polymorphic variants of genes FCGR2A (His 1 66Agr), CD14 (C-159T). IL1ß (T-31C), IL2 (7:330G) and 7LR2 (Arg753Ghn) and development of various forms of B-cell tumors of lymphatic system in 80 patients was investigated. The statistically significant differences of rates of particiular genotypes of single nucleotid polymorphisms of genes FCGR2A, CD14. IL1ß, IL2 and TLR2 in patients with indolent and aggressive types of course of non-Hodgkin lymphoma and also multiple myeloma. The results prove hypothesis that genetic variants of genes of inborn immune response effect the origin and character of course of different types of lymphoproliferative diseases. The markers can become additional prognostic characteristics of benign and aggressive course of tumors.
