BACKGROUND: Ultrasonography is limited for differentiating portal hypertension due to liver cirrhosis from that secondary to hepatosplenic schistosomiasis (HSS). We aimed to investigate the role of transient elastography (TE) in differentiating HSS mansoni from cirrhosis and the factors associated with liver and spleen stiffness (LS and SS) in HSS.
METHOD: A cross-sectional study was conducted including patients with HSS mansoni (n=29) and liver cirrhosis due to non-alcoholic steatohepatitis (n=23). All patients underwent TE and those with HSS were assessed by the Niamey protocol.
RESULTS: HSS subjects presented lower median LS (9.6 vs 21.3 Kpa, p<0.001) and liver controlled attenuation parameter (229 vs 274 dB/m, p=0.010) than cirrhosis subjects, in addition to higher SS (73.5 vs 42.2 Kpa, p=0.002). The area under the receiver operating characteristic curve for detecting cirrhosis by LS was 0.947 (95% CI 0.89 to 1.00, p<0.001), with an optimal cut-off of 11.75 Kpa. In HSS subjects, higher SS was associated with the presence of the following: diabetes mellitus (p=0.036), metabolic syndrome (p=0.043), esophageal varices (p=0.001), portal vein thrombosis (p=0.047) and previous variceal bleeding (p=0.011). In HSS patients without portal vein thrombosis, variceal bleeding was associated with higher SS (p=0.018). Niamey categories were not associated with LS (p=0.676) or SS (p=0.504).
CONCLUSION: TE can play a role in differentiating HSS from cirrhosis, especially by LS. SS may be further investigated for predicting complications in HSS.
