THE ROLE OF THE KIDNEYS IN THE REGULATION OF THE ACID - BASE BALANCE OF THE BLOOD IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE.

OBJECTIVE

The aim: To study the regulation of acid-base balance and blood acid - renal excretory function in patients with COPD.

PATIENTS AND

METHODS

Materials and methods: We examined 82 people, suggests that even during the most severe stages of COPD. Group 1 included 56 patients with COPD, group C. The average age was 60.54 + 2.04 years old, including 24 men and 32 women. The second group included 16 patients with COPD, group B, whose average age was 55.37 + 3.21 years old, including 7 men and 9 women. The third group included 10 healthy individuals, with an average age of 34.30 + 2.21 years, including 6 men and 4 women. Respiration function was evaluated on the basis of the forced expiratory curve recorded on a Spirolab II MIR S / N computer spirograph. The following indicators were evaluated: forced vital capacity (FVC), forced expiratory volume (FEV1) and FEV1 / FVC ratio.

RESULTS

Results

For all patients with COPD there is a characteristic presence of acidosis (pH in patients with COPD group B - 7,34 ± 0,01, in patients with COPD group C - 7,31 ± 0,07). For patients with COPD group C there are pronounced respiratory disorders (pCO2 - 48,25 + 1,14 mm Hg, p02 - 28.07 +1.37 mm Hg). For patients with COPD group B characteristic metabolic disorders (BE--3,71 + 0,57), which increase as the disease progresses. For patients with COPD group C this figure is equal to 7.62 + 0.49. Thus, the analysis of indicators indicates the presence for all patients of mixed (respiratory and metabolic) acidosis, which increases as the chronic obstructive pulmonary disease progresses.

CONCLUSION

Conclusions

There is activation of acid - renal excretory function and the inclusion of renal mechanisms in the regulation of acid-base balance.
