Background. High mortality in peritoneal dialysis (PD) patients is associated with the presence of nontraditional cardiovascular risk factors, such as malnutrition. However, hypoalbuminemia in patients undergoing PD may have gender-dependent consequences.
Objectives. The aim of the study was to evaluate the relationship between hypoalbuminemia, overhydration (OH), inflammation, and cardiovascular risk, depending on gender.
Material and Methods. The group studied consisted of 54 PD patients: 26 male (mean age: 59 ±19 years) and 28 female (mean age: 52 ±15 years). Serum albumin levels were measured routinely by the hospital central laboratory. The degree of OH was assessed by bioelectrical impedance analysis (BIA). Serum concentrations of C-reactive protein (CRP) and interleukin (IL)-6 were measured as inflammatory markers. Levels of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and troponin T (TnT) were used to assess cardiovascular risk.
Results. Median serum albumin concentration was 3.9 g/dL (3.6–4.2 g/dL). Both genders were comparable regarding most parameters except body weight (79 ±16 kg vs 67 ±16 kg; p = 0.009), but no differences were observed in body mass index (BMI) (26.3 ±5.0 kg/m2 vs 26.2 ±5.9 kg/m2; non significant (NS)). There was also no difference in the prevalence of hypoalbuminemia between female and male PD patients (23% vs 21%; NS). In females, low serum albumin concentrations were associated with OH, inflammation and cardiovascular risk, while in males serum albumin levels correlated with the parameters of dialysis and cardiovascular risk.
Conclusion. The impact of hypoalbuminemia may be gender-dependent. It seems that hypoalbuminemia is more important for female patients. It is also possible that different mechanisms regulate serum albumin concentration in female and male PD patients.
