[The characteristics of hematuria in chronic glomerulonephritis and nonglomerular diseases of the kidneys and urinary tract].

Upon the analysis of qualitative and quantitative characteristics of hematuria in renal and urinary tract affections it was established that whatever the red blood cell count in the urine, hematuria is primarily glomerular in contrast to nonglomerular in chronic glomerulonephritis and nonglomerular diseases of the kidneys and urinary tracts, respectively. Morphologic studies of urinary red blood cells using phase-contrast microscopy proved a valuable tool for identification of hematuria origin.

[Systemic lupus erythematosus and pregnancy: specific features of gestation and course of the disease].

The authors analyze the course and outcomes of 33 pregnancies in 26 women suffering from systemic lupus erythematosus (SLE). In patients with active SLE the incidence of gestoses and abnormalities of the newborns is significantly higher than in those with inactive SLE, whose gestational and neonatal complication rate is almost the same as in healthy women. Pregnancy course and outcomes are particularly unfavorable in cases with lupus glomerulonephritis.

[The beta 2-microglobulin content of the blood serum and urine in patients with primary chronic and lupus glomerulonephritis].

The authors studied the content of beta 2-microglobulin (beta 2-MG) in the blood serum and its excretion with the urine in 85 patients with chronic and 35 with lupoid glomerulonephritis (CGN and LGN) depending on the activity of the disease and state of the renal function. In active CGN and LGN one could observe a distinct increase of the content of beta 2-MG in the blood serum and an increase of its excretion with the urine that may be related to presence of marked dystrophic changes of the canalicular apparatus of the kidneys leading to disorders of reabsorption and beta 2-MG catabolism as well as disorders of the immune homeostasis revealed in these diseases. Results indicate that the beta 2-MG levels in the blood serum and urine may be considered as criteria of CGN and LGN activity.

[The efficacy of the allopurinol treatment of patients with gouty nephropathy].

The efficacy was studied of using allopurinol in 68 patients with primary podagra. The obtained results were compared with the treatment of 118 other patients who received similar treatment but without allopurinol (zanthinoxidase inhibitor). Allopurinol increased essentially the efficacy of therapeutic measures though positive dynamics concerning the renal process was achieved in 1/3 of patients.

[Significance of the studies of urinary syndrome in clinical practice].

The study of urinary sediment is essential in laboratory diagnosis. Conventional clinical methods are now used in line with computer-aided techniques and additional microscopy of the sediment elements. The paper provides a brief analysis of clinical situations characterized by appearance in the urine of abnormal numbers of leukocytes, erythrocytes, casts; provides clinical assessment of additional microscopic methods able to accentuate qualitative characteristics of the urinary syndrome; considers possibilities of application of the urinary sediment data in follow-up to improve diagnosis and control on-going treatment.

[Chromosome aberration levels and their dynamics during the treatment with cytotoxic preparations of patients with primary and lupus glomerulonephritis].

As many as 96 patients with chronic glomerulonephritis (CGN) and 25 with lupus glomerulonephritis (LGN) were examined for chromosomal aberrations (CA) in peripheral blood lymphocytes in different clinical variants and morphological forms of CGN and LGN as well as for their dynamics under the influence of cytotoxic drugs. In patients with active CGN and LGN, chromosomal instability may develop. The treatment with cyclophosphamide in a dose of 2.0-2.5 mg/kg/day appreciably increases chromosomal instability the level of which rises progressively with the treatment period increase. The treatment with azathioprine in a dose of 1.5-2.0 mg/kg/day is not associated with a noticeable increment of the rate of CA. The studies of the level of CA can be used for estimating CGN and LGN activity. Chronic renal failure did not change the level of CA either in CGN or in LGN. In different morphological forms of glomerulonephritis, the rate of CA was determined by the clinical variant of the disease. In order to reduce potential complications provoked by the treatment with cytotoxic drugs, dynamic studies of the CA rate should be carried out in addition to the conventional tests.

[The lipid peroxidation characteristics in the liver function disorders of patients with vasorenal hypertension].

The authors investigated the functional state of the liver and lipid peroxidation in vasorenal hypertension. Results indicate that the functional state of the liver in vasorenal hypertension is disturbed as a result of the main renal disease and also under the effect of arterial hypertension as a destabilizing factor leading to disorders of the hemodynamics and furthering potentiation of lipid peroxidation processes in the body.

[The characteristics of the disorders of the immune status in gout patients].

An analysis was made of some immunological indices in patients with podagra. It was established that women showed a more pronounced reduction of T-lymphocytes in the peripheral blood and their functional activity in tests with phytohemagglutinin and concanavalin as well as a deficit of B-lymphocytes, hyperproduction of C-immunoglobulin and antibodies to DNA in the blood serum. Males showed an increased level of B-lymphocytes. M-immunoglobulin and antirenal antibody titers. The concentration of circulating immune complexes in the blood rose equally independent of age.

[Birefringent fat bodies in the urine of patients with primary and secondary glomerulonephritis].

Results are presented of an investigation of birefracting fatty bodies in the urine of patients with primary chronic lupoid and Henoch glomerulonephritis. There was a close correlation between the presence of birefracting fatty bodies and severity of glomerulonephritis independent of the morphological picture of the disease and state of renal function. Reduction of the activity of the disease in the course of pathogenetic treatment characterized by a decrease or disappearance of proteinuria was accompanied by a distinct reduction of the level of birefracting fatty bodies or their disappearance.

[The immunological indices in different types of gouty nephropathy and the degree of renal structure involvement].

Patients with different types of podagric nephropathy were examined for 21 indicators of the functional activity of T and B lymphocytes and neutrophils. The data obtained were compared to the degree of impairment of the basic renal structures. Among the study immunologic indicators to estimate the gravity of morphological alterations in the glomeruli, the decrease of the titers of antibodies to DNA is of definite specificity, whereas the fall of the concentration of circulating immune complexes is of definite specificity in the assessment of alteration in the stroma.

[Gouty heart defects].

The authors revealed heart failure in 7 of 216 patients with gout. Two of them showed isolated mitral valve insufficiency and two patients aortal insufficiency while combined aortal disease, combination of mitral and aortal insufficiency and combined mitral valve disease with aortal insufficiency occurred each in 1 patient. One could not find distinct dependence between the clinical variant of the course of gout and development of a definite heart failure. Clinical and electrocardiographic signs of the revealed kinds of cardiac abnormalities are described. The morphological changes of the valves are described on the basis of 2 autopsy cases. The possible mechanism of development of podagric heart failures is discussed.

[Chromosome aberrations in chronic and lupus glomerulonephritis ].

The levels of aberration of chromosomes in peripheral blood leucocytes were investigated in patients with chronic and lupoid glomerulonephritis considering the clinical variants and morphological forms of the disease. In chronic glomerulonephritis high levels of chromosome aberration were found in patients with nephrotic type; in lupoid glomerulonephritis the frequency of chromosome aberration was higher in patients with active glomerulonephritis. Chronic renal failure did not essentially change the level of chromosome aberration both in chronic and lupoid glomerulonephritis. In different morphological forms of glomerulonephritis the frequency of chromosome aberration was determined by the clinical variant of the disease.
