The invention relates to medicine, namely to clinical laboratory diagnostics, and relates to the prediction of infectious complications in patients with acute lymphoblastic leukemia (ALL) receiving treatment with modern chemotherapy protocols (XT).
Acute leukemias (AL) lead to significant impairment of the immune system. Already at diagnosis is often found in patients with fever or infection. Infectious diseases occur in more than 50% of patients receiving XT about OL . The consequence of XT is neutropenia, during which the frequency of infectious complications increases to 80% .
In ALL all patients demonstrated functional defects of cells both before treatment and during remission and in the development of relapse . The factors that reduce cellular and humoral immunity, include long-term use of corticosteroids, purine analogues, alemtuzumab, alkylating drugs, methotrexate, rituximab. Glucocorticoids at a dose equivalent to 15 mg or more of prednisone per day, for the duration of the 1 month cause severe suppression of T-lymphocytes in a dose equivalent to 40 mg or more of prednisone per day, cause inhibition of the production of antibodies by b-lymphocytes .
In modern programs of treatment for ALL (Hoelzer, ALL-2005, MV-2008, ALL-2009) during predpisu and I FA�s induction daily from the 1st to the 28th day of therapy used prednisone at a dose of 60 mg/m 2a day or dexamethasone at a dose of 10 mg/m2. Glucocorticoids are administered during consolidation courses for 7 days, during maintenance 3 days.
It is important to note that severe infections in patients with weakened immune systems, which are ALL patients, may occur almost imperceptible symptoms. For example, pneumonia during neutropenia initially accompanied by only a slight shortness of breath or cough. In addition, any infectious disease can manifest non-specific symptoms such as fever or malaise . Manifestation of infection only in the form of hyperthermia is observed in 30-50% of patients. And in 15.3% of patients receiving modern XT, severe infection is not accompanied by fever and occur at normal body temperature. Particularly common infectious episodes without fever or low grade fever was observed in patients receiving corticosteroids at the time of their development or in history [3, 8, 10]. When agranulocytosis temperature over 38°C, maintained for 2 hours and not related to administration of blood components or drugs, is regarded as infectious fever . In case of fever or infection, the source of which in patients with AL is not always known, occurs when the neutrophil count is more than 1×109l, pok�needs urgent examination and immediate initiation of empiric therapy .
It is known that infection complicates the course and treatment of herpes zoster, cause activation of intravascular coagulation by minor deviations of a number of indicators of coagulation, to pronounced shifts that lead to severe disseminated intravascular coagulation (DIC). DIC is a natural manifestation of sepsis [1, 6, 12]. Appearing in the blood microorganisms or their waste products cause the release of inflammatory mediators (prostaglandins, interleukins, tumor necrosis factor, etc.) that play a significant role in activation of the coagulation cascade . Most severe hemorrhages seen in patients with acute leukemia, because infectious activation of coagulation occurs on the background of thrombocytopenia. Based on the above we can assume that a number of indicators of drug test etc, anticoagulant and fibrinolytic systems can be objective prognostic markers not only of thrombohemorrhagic, but also infectious and inflammatory processes.
With a view to the timely diagnosis and establish any necessary treatment of complications patients of herpes zoster need a thorough daily inspection and regular laboratory tests. The basic rule that determines the treatment strategy, the physician should assume that all bol�tion OL with fever infection exists, until proven otherwise . Thus, development of methods for early detection of infection in ALL patients with no visible lesions seems urgent. This will ensure timely administration of antimicrobial drugs and improve treatment outcomes.
The closest analogue to the claimed invention is "a Method of determining hemostatic criteria of adverse outcome of sepsis in patients with acute myeloid leukemia" (EN 2320996 Tarasova L. N. etc., priority of 05.07.2006) , in which to establish adverse outcome of sepsis determine the concentration of fibrinogen, the level rfmk in ethanol test and D-dimer levels and the amount of fibrinogen 6.0 g/l and more, rfmk above 3.7 V CONV.ed. and D-dimers in the range of 1001-2000 ng/ml or more state poor prognosis, which can lead to the development of multiple organ failure (MOF) and death. However, the findings in relation to patients with acute myeloblastic leukemia (AML), may not apply to ALL patients because of tumor substrate leukemia data are cells that have different immunological activity (myeloid or lymphoid series). In addition, the analog shows the clinical and laboratory criteria for the development has already occurred in patients with sepsis and its harmful� flow with possible formation of MOF and death.
The object of the present invention is the prediction of ALL patients on the background of XT of infection at an early stage, if the results of the study of a number of indicators of coagulation hemostasis.
The essence of the claimed invention lies in the fact that ALL patients receiving treatment according to modern protocols XT, 2-3 times per week determine the concentration of fibrinogen, time Xiia-dependent èuglobulinovyj lysis (Hiia-SEL), the level of soluble fibrin-monomer complexes (SFMC), activity of protein C (PRs) and the detection of at least 2 of 4 criteria, namely: raising the level of fibrinogen at ≥ 41%, rfmk - ≥ 76%, the elongation time Hiia-SEL to ≥ 11% and the decrease in the activity of PRs at ≥ 12% compared to the previous study, predict the development of infectious complications.
The technical result
The method provides early prediction of the development of infection in patients during the XT.
A method of predicting the development of infection in ALL patients is as follows. In patients with ALL receiving XT in addition to standard surveys (thorough daily inspection, conducting bacteriological and biochemical studies, the General analysis of blood and urine) to determine the rates of coagulation. For this purpose blood is taken in a plastic tube containing an anticoagulant is 3.8% RA�creative ways to 5.5 aqueous sodium citrate (0,11 mmol/l) in a ratio of 9:1. Allowed taking blood in a vacuum tube, also containing 3.8% sodium citrate (blue cap). Then obtain platelet-poor plasma, centrifuger blood at room temperature and 1000-2000 rpm for 10 min. the Concentration of fibrinogen is determined by the method of Clauss; time XIIa-dependent èuglobulinovyj lysis (Hiia-SEL) - A. G. Arkhipov and G. F. Eremin; the level of soluble fibrin-monomer complexes (SFMC) in orthophenanthroline test V. A. Lukombo and A. P. Momot . The activity of protein C (PRs) determine amylolyticus method using sets of "Refrom-Protein C" (NGO "RENA", Moscow).
% change index is calculated as follows:
where X1- the index value for the last number;
X2- the index value for today's (current) number.
CLINICAL and LABORATORY STUDIES
The proposed criteria for the prediction of infection derived from the results of the analysis of 40 infectious episodes were observed at different stages of treatment in ALL 17 patients (8 men, 9 women) aged from 16 to 71 years (median 40 years). Therapy patients underwent the following protocols: ALL-2005 - 6 persons, MV-2008 - 3, ALL-2009 - 8. The indicators of hemostasis in patients was determined regularly, 2-3 times a week. The results obtained on the day of pervaporative infection (appearance of the hearth, or increased body temperature) (sample 2), were compared with those obtained the day before, on a clean background when there were no any signs of infection (sample 1). The data presented in table 1.
|Indicators of hemostasis in ALL patients without infection and its development on the background of XT (median, minimum-maximum values)|
|Indicators||sample 1 (no infection)||sample 2 (infection)||healthy subjects (n=35)|

|Time CPA-SEL, min||7,8||22*||7,0|
|* - the difference from the norm, p<0,05 (criterion Kruskal-Wallis test)|
From table 1 it is evident that the levels of fibrinogen, Hiia-SEL and rfmk ALL patients without infectious complications did not differ from the norm and started to exceed it during the accession of infection. The activity of PRs on a clean background was increased. Obviously, this compensatory reaction in response to activating the hemostatic effect of leukemic process XT and aggressive. Under the influence of infection intravascular coagulation is enhanced, resulting in the consumption begins PRs, resulting in a reduction of its activity to the levels of norms, and the emergence markers thrombinemia - rfmk.
Indicators prior to infection and at the beginning were compared in pairs (Wilcoxon test analysis dependent variables); it revealed significant differences for all studied parameters (p<0,05).
To identify the extent of changes in the levels of fibrinogen, rfmk, time Hiia-SEL, PRs activity was compared the results of their studies, every patient�NTA before and during infection and determined, how much % of the original value has changed indicator. Then we calculated the median change in the level of the index, and 1 and 3 quartiles (Q1 and Q3) (tables 2 and 3).
It was found that the concentration of fibrinogen in the development of infection was increased on average by 74%, time Hiia-SEL lengthened by 73%, the level rfmk increased by 333% (more than 3 times), and the PRs activity was decreased by 17%. After calculating the lower quartile had proposed the following criteria for prediction of infection: increased fibrinogen concentration at ≥ 41%, rfmk - ≥ 76%, the elongation time Hiia-SEL to ≥ 11% and decrease of activity of DSC - ≥ 12%.
