OBJECTIVE: Respiratory alkalosis (RA) and dilutional hyperchloremic acidosis (DHA) are the most common acid-base balance (ABB) disorders in patients with liver cirrhosis. The aims of this study were to clarify whether RA develops in relation to DHA via respiratory compensation of metabolic acidosis and whether spironolactone in combination with low-dose furosemide - diuretics known to ameliorate DHA - positively affects RA in liver cirrhosis patients.
MATERIALS AND METHODS: 59 patients with advanced cirrhosis were divided into two groups. Group D consisted of individuals (urine sodium concentration (UNa+) > 20 mmol/L) who responded to combination therapy consisting of spironolactone and low-dose furosemide. The non-D group consisted of individuals (UNa+ ≤ 20 mmol/L) who either did not respond to the treatment or who were not administered it. In both groups, we examined serum and urine concentrations of electrolytes and ABB parameters, including SNa+-SCl- and SNa+/SCl- values.
RESULTS: In group D, we found a statistically significant relationship between pCO2 and SHCO3-: r = 0.756 (p < 0.001) and between pCO2 and SNa+-SCl-: r = 0.522 (p = 0.001). Neither Salb nor the corrected anion gap were associated with changes in SHCO3- or pCO2 values. Although SHCO3- values were normal, abnormal pCO2 values were observed in one third of group D patients. Based on multivariable analysis, SHCO3- proved to be a statistically significant influencing factor on pCO2 values.
CONCLUSION: DHA contributes to the development of RA in individuals with liver cirrhosis. Reducing DHA by means of effective diuretic therapy comprising spironolactone and furosemide has a beneficial effect on RA in such patients.
