Introduction. Systemic lupus erythematosus (SLE) is a complex autoimmune disease with variable clinical manifestations associated with multiple autoantibodies formation and deposition of immune complexes, and other immune processes. Despite significant advances in treatment, the disease remains disabling, in particular, due to increased bone fragility and low-energy fractures. The study of bone remodeling in patients with SLE should help to improve the therapy and quality of their treatment.

The aim of the study. To investigate the features of bone mineral density, calcium-phosphorus metabolism and bone remodeling in patients with systemic lupus erythematosus.

Materials and methods. The study involved 123 women with SLE aged 21-51 years. The comparison group (CG) consisted of 25 women without SLE in premenopausal status of the appropriate age. The control group included 25 practically healthy women.

In order to study bone mineral density (BMD), dual-energy X-ray densitometry (DXA) of the lumbar spine was performed using a dual-energy X-ray absorptiometer. For the study of calcium-phosphorus metabolism (CPM), total calcium (Ca), ionized Ca, phosphorus (P) in blood and Ca, P, creatinine in daily urine, as well as parathyroid hormone (PTH) and 25-hydroxyvitamin D in serum were determined. Markers of bone remodeling (osteocalcin, procollagen type 1 amino-terminal propeptide (P1NP) and isomerized C-terminal telopeptide (β-crosslaps) in serum were measured.

To achieve the stated goal, the first step included the determination of bone damage prevalence in patients with the diagnosed SLE; the second step was directed towards the characterization the particular bone condition in patients with SLE based on the results of BMD, CPM indices and markers of bone remodeling assessment.

Results. According to the results of DXA of the lumbar spine, 88 (71.54 %) women of the SG and only 8 (32.00 %) women of the CG had a decrease in BMD (p < 0.001). According to the mean values, the studied CPM indices of the SG patients, CG and control group wemen exposed no significant differences. Similarly, no significant differences were detected in the mean values of urinary phosphorus and in between blood PTH values in SG, CG, and control. The level of 25-hydroxyvitamin D was significantly lower in SG (15.14 ± 0.80 ng/ml) than in CG (19.62 ± 0.46 ng/ ml) and control (22.38 ± 1.34 ng/ml) p < 0.05. The mean value of osteocalcin in woman with SLE was significantly lower than in CG and control (11.81 ± 0.49 ng/ml versus 18.61 ± 0.75 ng/ml and 19.28 ± 1.88, p < 0.001). No significant difference were detected in between the mean values of P1NP in SG, CG and control. The mean values of β-cross laps were significantly higher in patients with SLE (0.51 ± 0.02 ng/ml) compared to GC (0.26 ± 0.02 ng/ ml) and control (0.28 ± 0.02 ng/ml), p < 0.001.

Conclusions. Bone mineral density, calcium-phosphorus metabolism and bone remodeling in patients with systemic lupus erythematosus have peculiarities as follows: a significant decrease in bone mass in 71.54 % of patients, namely 18, 70 % - grade I osteopenia, 21.14 % - grade II osteopenia, 14.63 % - grade III osteopenia; 17.07 % - osteoporosis, increased calcium excretion, vitamin D deficiency, decreased osteoblastic and enhansed osteoclastic functions.

The aim of the study. To determine the frequency and character of syntropic extrahepatic lesions in cirrhotic patients depending on the hepatopulmonary syndrome severity degree.

Materials and methods. In a randomized manner with preliminary stratification by the presence of hepatopulmonary syndrome were studied 93 patients with liver cirrhosis, who underwent the comprehensive clinical-laboratory and instrumental examination.

Results. According to the obtained results, most often in patients with liver cirrhosis associated with hepatopulmonary syndrome syntropic extrahepatic lesions affected other organ systems as follows: digestive system - 100.0 % patients under investigation; hematopoietic system - 84.9 %; nervous system - 81.7 %; integumentary system and mucous membranes - 78.5 %; blood circulatory system - 76. 3 %; osteoarticular system - 67.7 %; urinary system - 22.6 %. Increased severity of hepatopulmonary syndrome significantly (p < 0.05) correlated with thein creased frequency of lesions.

Among syntropic polymorbid lesions of the integumentary system and mucous membranes, 68.8 % patients with hepatopulmonary syndrome had jaundice, 66.7 % - telangiectasia. Among lesions of the osteoarticular system osteopenia was diagnosed in 44.7 % of patients, osteoporosis - in 27.7 %. Among lesions of the circulatory system 52.7% of patients suffered from heart rhythm disorders, 49.5 % - from arterial hypotension, 20.4 % - from cirrhotic cardiomyopathy. Among lesions of the hematopoietic system anemia (76.3 %), coagulopathy (73.1 %) and thrombocytopenia (61.3 %) were diagnosed most often. Digestive system lesionsinclude esophageal veins varicosities (94.6 % of patients), hemorrhoidal veins varicosites (68.8 %), and cirrhotic gastropathy (62.4 %). Among lesions of the urinary systemin 21.5 % of patientswas diagnosed type II hepatorenal syndrome. Among the lesions of central nervous system in 81.7 % of patientswas diagnosed hepatic encephalopathy. The frequency of syndromes and nosological units increased significantly (p < 0.05) with the increase of hepatopulmonary syndrome severity.

Conclusions. 100.0 % patients with liver cirrhosis accompanied byhepatopulmonary syndromewere affected by syntropic polymorbid lesionsof the digestive system, 94.6 % of which were represented by esophageal vein varicosites. Out of 84.9 % of patients with hematopoietic lesions anemia was diagnosed in 76.3 %, coagulopathy - in 73.1 % of cases. Of total 81.7 % patients withnervous system injurieshepatic encephalopathy was diagnosed in 81.7 % patients. In 78.5 % cases of damaged skin, its appendages and mucous membranesjaundice covered 68.8 %, and telangiectasia 66.7 % of cases. In 76.3 % of cardiovascular system lesions arrhythmias were diagnosed in 52.7 %. With the increasing severity of hepatopulmonary syndrome, the frequency of the above lesions increased significantly (p < 0.05).

Introduction. The problem of osteoporosis (OP) has become an epidemic unprecedented in its scale. Numerous studies of various aspects of OP leave out men with a history of gastric resection (GR) as a result of complicated peptic ulcer disease (PUD). Therefore, a detailed characteristics of clinical parameters and hormonal and metabolic homeostasis in men with postgastric resection disease (PGRD) and comorbid OP will allow the improvement of the treatment and prevention of osteodeficiency conditions in this category of patients.

The aim of the study. To characterize clinical parameters and hormonal and metabolic homeostasis in men with postgastric resection disease and comorbid osteoporosis.

Materials and methods. 164 men with PGRD and comorbid OP were examined with preliminary random stratification by the presence of a history of five or more years of GR surgery as a result of complicated PUD. In addition to routine examinations, hormonal homeostasis was studied by the effect of hormones on protein metabolism: anabolic (growth hormone, parathyroid hormone, gastrin, and testosterone) and catabolic (triiodothyronine, thyroxine, glucagon, and cortisol) hormones and cyclic nucleotides. Plasma electrolytes and protein profile were also analyzed.

Results. It was established that the vast majority of patients who underwent the surgery with PGRD and comorbid OP have clinical signs of calcium metabolism disorders. They had significant abnormalities in hormonal and metabolic homeostasis manifested by dyshormonemia, dyselectrolytemia and dysproteinemia. We believe that these scientific facts will help to improve the treatment and prevention of secondary osteoporosis complications in this category of patients.

Conclusions. Among the clinical parameters in men with PGRD and comorbid OP, bone pain and muscle cramps prevailed. Hormonal homeostasis was characterized by dyshormonemia with a significant decrease in almost all studied anabolic hormones and an increase in almost all studied catabolic hormones. Deviations in metabolic homeostasis were manifested by dyselectrolytemia (hypophosphatemia, hypomagnesemia, decreased ionized calcium) and dysproteinemia (hypoalbuminemia, hyper-a₁-globulinemia, hyper-β-globulinemia, sharply reduced glycoproteins).

Introduction. Systemic lupus erythematosus (SLE) is an autoimmune rheumatic disease with numerous clinical manifestations that affects any organs or systems and requires a comprehensive study.

The aim of the study. To find out the clinical markers of the heart and blood vessels syntropic lesions in patients with SLE and evaluate their diagnostic value.

Materials and methods. The study included 118 patients with SLE with the presence of syntropic (having common etiological and/or pathogenetic mechanisms with the main disease) lesions of the heart and blood vessels (107 women (90.68%) and 11 men (9.32%) aged 18 to 74 years (average age 42.48 ±1.12 years)).

The study included the identification of clinical markers of syntropic lesions of the heart and blood vessels, determination of the diagnostic value of individual clinical markers and their constellations in terms of sensitivity, specificity and accuracy in patients with SLE, and the identification of one of them with the most reliable diagnostic value.

Results. Clinical markers for detecting mitral valve insufficiency in patients with SLE are morning stiffness, new rash, dyspnea, memory problems, presence of weakened cardiac sounds, systolic murmur on the apex of the heart, accent of the second sound on the pulmonary artery; mitral valve consolidation - new rash, the presence of legs edema, dyspnea, a feeling of interruptions in the work of the heart, pain in the heart area, the presence of weakened cardiac tones, systolic murmur on the top of the heart; myocarditis - muscle ache, alopecia, legs edema, shortness of breath , palpitation, systolic murmur on the top of the heart; pericardial effusion – legs edema, dyspnea, palpitations, the presence of weakened cardiac tones; endocarditis - the presence of the accent of the second tone on the pulmonary artery.

The optimal value for the diagnosis of mitral valve insufficiency in patients with SLE is the constellation of clinical markers "pain in the joints + new rash + accent of the second tone on the aorta"; of mitral valve consolidation - "dyspnea + a feeling of interruptions in the work of the heart"; of myocarditis - "heart palpitations + systolic murmur on the apex of the heart"; of pericardial effusion - "pain in the joints + weakening of heart tones"; of endocarditis - "fever + systolic murmur over the top of the heart + emphasis of the second tone on the pulmonary artery".

Conclusions. In patients with SLE the optimal value among clinical monomarkers and their constellations for the diagnosis of mitral valve insufficiency is dyspnea and the constellation "pain in the joints + new rash + accent of the second tone on aorta"; for MV consolidation - a complaint of a feeling of interruptions in the work of the heart and the constellation "shortness of breath + feeling of interruptions in the work of the heart"; for myocarditis - palpitations and the constellation "heartbeat + systolic murmur on the apex of the heart", pericardial effusion - the presence of weakened cardiac tones and the constellation "pain in the joints + weakened cardiac tones"; for endocarditis - accent of the second tone on the pulmonary artery and the constellation "fever + systolic murmur on the apex of the heart + accent of the second tone on the pulmonary artery". Constellations of clinical markers, but not individual clinical markers, have optimal value for the diagnosis of the syntropic heart lesions in patients with SLE.
