Summary

Background:

Ascites is a product of fluid accumulation within the peritoneal cavity. Underlying etiologies include cirrhosis, congestive heart failure (CHF), nephrotic syndrome, and malignancies. Patients with cirrhotic ascites are at increased risk for infections, especially spontaneous bacterial peritonitis (SBP), which is associated with high rates of morbidity and mortality. Ascites is diagnosed both clinically and sonographically. SBP is diagnosed via abdominal paracentesis, a relatively safe and effective procedure. However, abdominal paracentesis carries risks such as bleeding, bowel perforation, and infection.

Objectives:

To identify new inflammatory markers as alternative or replacement methods for accurately evaluating patients before and after abdominal paracentesis and how these new inflammatory markers can be evaluated from a simple, inexpensive, and routinely performed blood sample.

Methods:

A total of 106 patients admitted with ascites were classified into three groups based on the underlying etiology of their condition: malignant ascites (30 patients), ascites secondary to CHF (30 patients), and ascites secondary to cirrhosis (46 patients). Levels of neutrophil-lymphocyte ratio (NLR), mean platelet volume, and C-reactive protein among the study groups were examined through blood samples and subsequently compared

Results:

NLR values within malignant ascites and CHF ascites were significantly higher than cirrhotic ascites (P = 0.002). In addition, among risk factors for developing ascites, significant correlations were found among the three groups in hypertension (P < 0.001), diabetes mellitus (P = 0.003), hyperlipidemia (P = 0.002), CHF (P < 0.001), and ischemic heart disease (P < 0.001) variables.

Conclusions:

NLR may be a prognostic tool in patient evaluation of ascites.
