[Ecopathology of the kidneys and individual sensitivity to heavy metal salts].

Investigations performed in the region contaminated with heavy metal salts revealed high prevalence of renal diseases in children. The test for blood polymorphic proteins indicated signs of genetic predisposition to renal damage. Greater occurrence in the population with econephropathy of a rare allele of transferrin C3 may be the cause of enhanced oxidative-radical processes in renal cells.

[Nephropathies in a region contaminated by heavy metal salts and the possibilities for therapeutic and prophylactic measures].

The study of the population in the region contaminated with heavy metal salts has revealed high incidence of nephropathies even in preschool children manifesting initially in the majority of cases with hematuria. All the patients had the signs of urinary dysembryogenesis and marked membranopathological process. Long-term exposure to even small doses of heavy metals is supposed to cause nephropathy.

[Current concepts of oxalate nephropathies (clinical and population studies)].

The paper presents the results of clinical and laboratory examination made in 3 groups of children: populational, hospital and control (a total of 176 patients). The children were diagnosed to have variants of dysmetabolic nephropathy (DN) which had become a problem not only for urolithiasis-endemic regions, but also for the Middle Russia. The study involving characterization of cytomembranes, renal tissue biopsy allowed conclusion on nonspecific DN symptoms.

[Plasmapheresis in the combined therapy of progressive forms of glomerulonephritis].

29 patients aged 6-16 with glomerulonephritis lasting 4-5 years received multimodality treatment with plasmapheresis as a component. The majority of the patients suffered from primary glomerulonephritis in mesangio- or membrano-proliferative morphological variants. Previous long-term conventional therapy (prednisolone, cytostatics, anticoagulants and antiaggregation drugs) failed.
