[Computer morphometry of peripheral blood lymphocytes in elderly patients with chronic pyelonephritis.]

The aim of the study was to investigate the peculiarities of morphometric parameters of peripheral blood lymphocytes in chronic pyelonephritis in elderly patients in comparison with young and middle-aged patients. A total of 81 patients with chronic pyelonephritis in the exacerbation phase were examined. All patients were divided into three age groups according to WHO recommendations: the 1st - 42patients of young age (18-44 years); the 2nd - 17 patients of middle age (45-59 years); the 3rd - 22 elderly patients (60-74 years). Computer morphometry of lymphocytes was performed in all examined patients. In elderly patients with chronic pyelonephritis the size and сytoplasmic-nuclear ratio of lymphocytes increase. This indicates the preservation of lymphocyte defense responses at this age. In male patients with chronic pyelonephritis in the 1st and 2nd age groups the size of lymphocytes increases, and in female patients - decreases. The сytoplasmic-nuclear ratio increases in males of these age groups, while it remains unchanged or decreases in females. Indirect indications of reduced immunity in young and middle-aged women with chronic inflammation in the kidneys have been obtained.

[The blood system and bone marrow during aging. The new method of hemogram assessment: blood analysis along with synthesis].

This article represents the particularities of people's blood and bone marrow referent parameters during aging. On the basis of 56 blood parameters of apparently healthy people a mathematical model of blood's morphofunctional state during physical aging was created. The following integral changes have been discovered: in age group of 35-59 years the integral indicator amounts to 0.05 +/- 0.0008, it approaches the benchmark in elderly age (0.02 +/- 0.0001) and becomes negative with people of gerontic age (-0.06 +/- 0.0003). On the basis of 14 selected blood parameters a calculation of referent integral indicators of blood state for healthy people of various age groups was performed, which serve as standards in clinical practice. Out of 70 peripheral blood cells' indicators the integral indicators for patients suffering from community-acquired pneumonia were calculated. The organism reacts to pneumonia most appropriately at the age of 22-34 years (integral indicator amounts to -0.0386). In patients of 35-59 years the integral indicator descends closer to zero mark (-0.0236), pointing to minor reaction to inflammation. Patients over 60 years of age show the biggest divergence of integral indicator from the benchmark (-0.0613), which points to an inadequate reaction of the organism to inflammation in this age. Based on discriminant analysis of 80 indicators (clinical blood analysis, cytograms, cardiac beat count, breath count, C-reactive protein) the most informatory indicators used to create the algorithm for determination of pneumonia severity were chosen.

[Computer morphometry of peripheral blood cells in patients of different age with pneumonia].

The aim of the research was to study blood responses to pneumonia in patients of different age and sex. The subjects of the study were 116 patients with extrahospital bacterial pneumonia (80 men and 36 women). The patients were divided into three age groups: 18 to 44 years, 45 to 59 years, and 60 to 74 years. Almost healthy 16 men and almost healthy 14 women have made the control groups. Computer morphometry of leukocytes of peripheral blood was made to all patients. Various reaction of lymphocytes on a pneumonia in men and women of young and middle age was revealed. Indirect evidences of decrease in level of lymphocytes activation in women of young and middle age at pneumonia development were received. The sizes of lymphocytes in elderly patients with pneumonia do not change comparing with the control groups. Sexual differences in reaction of monocytes to pneumonia are not present. The sizes of monocytes in patients with pneumonia of all age groups decrease at the expense of kernels, which indicate to their accelerated manufacture in a marrow. Absence of increase in cytoplasm to nucleus ratio index in elderly patients testifies a smaller degree of monocytes activation in this group of patients. The trend to reduction of the sizes of neutrophiles speaks of the accelerated division of predecessors' of mature neutrophiles. The increase in cytoplasm to nucleus ratio index of neutrophiles in women with pneumonia of young and middle age comparing with the control group specifies to the big degree of activation of neutrophiles link in these groups.

[Peripheral blood responses in elderly patients with some prevalent diseases].

The aim of the research was to study blood responses to inflammatory processes in patients of different ages. The subjects of the study were 31 healthy persons and 198 patients, 116 of whom had pneumonia and 82 had chronic pyelonephritis. The patients were divided into three age groups: 16 to 39 years, 40 to 59 years, and older than 60 years. The following parameters were calculated on the basis of peripheral blood leukocyte composition and ESR: leukocyte intoxication index (LII), lymphocyte index (LymI), leukocyte shift index (LSI), leukocyte index (LI), leukocyte to ESR ratio index (LESRRI), lymphocyte-granulocyte index (LGI), total index (TI), neutrophile to lymphocyte ratio index (NLymRI), neutrophile to monocyte ratio index (NMRI), and lymphocyte to monocyte ratio index (LMRI). The majority of the indexes (LII, LymI, LSI, LI, LESRRI, LGI, and LMRI) in acute inflammation processes and some of them (LESRRI, NLymRI, and LMRI) in chronic inflammation altered significantly in all the age groups, which demonstrated that compensatory and adaptive mechanisms remained preserved in the elderly. The were age-dependent differences in blood responses to inflammation: LymI, LI, and LGI were significantly lower in the elderly with chronic pyelonephritis, whereas in Groups 1 and 2 there were no changes; NMRI was decreased in Groups 1 and 2 in chronic pyelonephritis and did not differ from the elderly controls. In acute inflammation, there were no significant differences from the controls in NlymRI in Group 3, while this parameter in Groups 1 and 2 differ from that in the controls. Thus, hematological indices make it possible to assess the work of effectory mechanisms of the immune system, the degree of their compensation in patients belonging to different age groups.
