ABSTRACT
OBJECTIVE:
This study aimed to analyze the effect of hyperbaric oxygen treatment (HBOT) in hepatopulmonary syndrome (HPS). MATERIALS ANDMETHODS:
Five-month-old female Wistar-Albino rats were randomly divided into three groups Group I, the control group; Group II, the cirrhosis group; and Group III, the cirrhosis group + HBOT group. Rats were exposed to HBO sessions (2.4 atm./60 min) for 20 days. Animals were sacrificed 24 hours after the last HBO session. Biochemical analysis, oxygenation parameters, NO and NO synthase (NOS) levels, histopathological changes in the liver and lungs, and pulmonary artery diameter were measured.RESULTS:
A total of 24 rats (10 rats were included in Group I, six rats in Group II, and eight rats in Group III) weighing 220-250 g were included in the study. Significant differences were observed for NO and NOS (9.10±1.05 to 12.17±1.85 µmol/L, p<0.05 and 0.46±0.31 to 1.17±0.39 U/ml, p<0.05, respectively) at baseline and day 36 only in group II. Inflammatory cell infiltration and bronchial injury were significantly increased in group II compared to group I (p=0.007 and p=0.008, respectively) but not in group III (p=0.266 and p=0.275, respectively). Pulmonary artery diameter was significantly lower in group III compared with group II at all sites in both lungs (p<0.05).CONCLUSIONS:
HBOT may be a promising treatment for HPS by reducing NO and NOS activity, perialveolar arteriolar dilation, lung inflammation, and injury and guiding future clinical trials.
