Usefulness of AF Lactoferrin Levels in Patients with Liver Cirrhosis to Diagnose Spontaneous Bacterial Peritonitis
Abstract Background Cirrhosis represents the final common histological pathway for a wide variety of chronic liver diseases. Occurrence of ascites is the most common presentation of liver cirrhosis. Spontaneous bacterial peritonitis (SBP) is observed in 15–26% of patients hospitalized with ascites. Objectives The aims of this study was to evaluate the usefulness of AF lactoferrin for the diagnosis of SBP and to identify a clinically useful cut-off level that can be used for future development of an important clinical, economic and time saving rapid bedside test for the diagnosis of SBP in cirrhotic ascites. Patients and Methods This study was conducted on 40 patients with decompensated chronic liver disease and ascites with and without spontaneous bacterial peritonitis admitted to Nasser institute for researches and treatment Hospital and Internal Medicine department, Faculty of Medicine, Ain Shams University from November 2017 to April 2018. Results Females were affected more than males by SBP, SBP has higher incidence in elderly compared to control group, no significant difference between studied groups regards to risk factors and Child class, HCV infection was the main etiology of liver cirrhosis in both groups while HBV infection was much less common with no significant difference between studied groups. Patients in SBP group showed positive reaction to CRP compared to control group with significant difference between them. No statistical significant differences between studied groups regards to abdominal ultrasonographic findings. Liver enzymes (ALT) and ALP were higher in SBP patients compared to non SBP patients with significant difference between them. SBP patients have higher TLC and lower MCV and platelets count compared to non SBP patients with significant difference between them. No statistical significant difference between studied groups regards to INR, Hb and MCH values. Conclusion Outcomes of our study provide evidence of the clinical usefulness of AF lactoferrin levels in patients with cirrhosis to differentiate those with and without SBP.
