THE ROLE OF MATRIX METALLOPROTEINASES IN PROCESSES OF HEART RE-MODELING IN CHILDREN WITH RESTRICTIVE CARDIOMYOPATHY
Restrictive cardiomyopathy (RCMP) is heart disorder with unclear etiology; it can be characterized as disease with disorder of diastolic myocardium function of left ventricle, conditioned by restriction. The chronic heart failure as a syndrome of RCMP can develop as a result of disbalance in system of complex biochemical, structural, and geometrical mechanisms of myocardium re-modeling. Extra cellular matrix play significant role in heart structure and geometry breaking. The destruction of heart is realized by matrix metalloproteinases (MMP). The activity of MMP, in its turn, is controlled by its tissue inhibitors. The present study analyzed the role of MMP in process of collagen’s synthesis and catabolism deregulation, myocardium fibrosis, change of heart chambers, and development of diastolic dysfunction in children with RCMP.Key words: children, chronic heart failure, restrictive cardiomyopathy, matrix metalloproteinases.(Voprosy sovremennoi pediatrii — Current Pediatrics. 2009;8(5):36-39
EXPERIENCE OF TREATMENT WITH IBANDRONIC ACID IN PATIENTS WITH SEVERE RHEUMATOLOGICAL DISEASES AND SYSTEMIC OSTEOPOROSIS
This article presents the results of a study of effectiveness and safety of ibandronic acid in 21 children with rheumatologic diseases and severe systemic osteoporosis. The treatment with ibandronic acid during 48 weeks provided statistically significant increase of mineral density of bones, decrease of pain intensity, lessening of serum concentration of bone resorption marker — C-terminal telopeptide. The development of repeated compressive fractures of vertebrae and bones of peripheral skeleton at the time of treatment with this medication was not detected. Key words: children, rheumatological diseases, osteoporosis, treatment, bifosfonates, ibandronic acid.(Voprosy sovremennoi pediatrii — Current Pediatrics. 2010;9(1):116-121
STATE OF THE MATRIX METALLOPROTEINASES AND THEIR ROLE IN FORMATION OF THE CHRONIC HEART FAILURE IN CHILDREN WITH DILATED CARDIOMYOPATHY
The article is devoted to an important section of the pediatric cardiology — dilated cardiomyopathy (DCMP). This is largely due to the spread of the given disease, its possible progress and tendency to the formation of the chronic heart failure (CHF). The progress in the research of the DCMP'accompanied CHF formation and development processes is the studies of the extracellular matrix status (EM), which is defined by the activity of the matrix metalloproteinases (MMP) and their tissue inhibitors (TIMMP). This article describes the complex clinical and biochemical studies of the serum MMP'1, MMP'2, MMP'9 and TIMMP'1 levels in children with DCMP at different stages of the illness course. MMP and their inhibitor concentration were defined by means of the enzyme'linked immunosorbent assay (ELISA). Based on the results from the morphofunctional studies and data of the biochemical analyses, the authors determined the importance of changes in the isomeric EM composition pertaining to the disturbances of the systolic and diastolic functions, as well as in heart remodeling for such children.Key words: chronic heart failure, dilated cardiomyopathy, extracellular matrix, matrix metalloproteinases, tissue inhibitors of the matrix metalloproteinases
DISTANT SHOCKWAVE LITHOTRIPSY IN CHILDREN
Shockwave lithotripsy implemented in the clinical practices in the 1980-s drastically altered the treatment approach for the urolithiasis and took a leading place in the therapy of this disease. The key task of the distant shockwave lithotripsy is to provide for the fast, reliable, safe and noninvasive kidney and renal duct litholysis. The article highlights the outcome of the shockwave lithotripsy application on Econolith 3000 for the treatment of 27 children. The results of the performed treatment indicated the high efficiency and low invasiveness of this method to eliminate the concrements, as well as the perspective of its use, including in the infants. Shockwave lithotripsy allows the specialists to abandon the traumatic surgeries.Key words: distant shockwave lithotripsy, urolithiasis, children

TUBULAR DISORDERS WITH RICKETS-LIKE SYNDROME
Often under the guise of «ordinary» Rickets are more severe kidney diseases, developing as a result of inherited or acquired, primary or secondary defects in the renal tubules. Incorrect diagnosis leads to an inadequate therapy, rapid progression of disease and renal failure. The article describes the main approaches to the diagnosis and treatment of disorders of tubular rachitis similar syndrome, presents a number of clinical cases in author's practice.Key words: tubulopathy, acidosis, electrolyte disorders, rickets, rickets-like syndrome, diagnostics, treatment, children

HOMOCYSTEINE AND KIDNEY'S FUNCTIONAL STATUS OF THE CHILDREN WITH THE NEPHROTIC SYNDROME
The authors presented the data on the homo cysteine serum concentration in the children with nephrotic syndrome. They established the high rate of hyper homo cysteinemia in the nephritic syndrome, but the degree of the homocysteine concentration increase is largely due to the kidney's functional status rather than the activity of the disease. They also discuss the pathogenetic role of hyper homo cysteinemia in the event of the chronic nephritic pathology.Key words: homo cysteine, nephrotic syndrome, children
