Background Spontaneous bacterial peritonitis (SBP) is an ascitic fluid infection in patients with liver cirrhosis in the absence of surgical causes. The drop of the ascitic fluid polymorphonuclear leukocyte count (AFPC) ≥25% of baseline 48h post-start of antibiotics is a predictor of antibiotic response. This study was designed to compare the diagnostic accuracy of AFPC 24h of antibiotic to the standard 48h. Three hundred ninety-nine SBP patients were classified into 2 groups. Group I (31.1%) are patients that lacked ≥25% drop and group II (68.9%) the opposite. Results The average age was 51.99 ±11.21 years. Most patients were males (70.9%), normotensive (75.8%), non-diabetics (50.8%), and without recent intake history of proton pump inhibitors (75.8%) and B-blockers (77%). Group II patients had statistically significant (p p>0.05). Group II patients compared to group I had statistically (p =0.001) lower AFPC 24h [800 (970) vs. 1100 (1700) cell/mm3], higher percent drop of the AFPC 24h [28.09 (24) vs. −10.17 (35)], and ≥25% drop [154 (90.6%) vs. 16 (9.4%)]. The 24h AFPC >980 cell/mm3 was associated with AFPC 48h non-response (AUROC =0.634, p =0.001, 58.87% sensitivity, 64.36% specificity). The 24-h AFPC percent drop >8% was associated with AFPC 48h response (AUROC =0.849, p=0.001, 85.82% sensitivity, 80.49% specificity). Conclusion Concordance of 24- and 48-h diagnostic follow-up ascitic fluid polymorphonuclear leukocyte count in the guidance of the antibiotic therapy.
