ABSTRACT
BACKGROUND AND AIMS:
Hepatic sinusoidal obstruction syndrome (HSOS) is caused by toxic injury to sinusoidal endothelial cells in the liver. The intake of pyrrolizidine alkaloids (PAs) in some Chinese herbal remedies/plants remains the major etiology for HSOS in China. Recently, new diagnostic criteria for PA-induced HSOS (i.e. PA-HSOS) have been developed; however, the efficacy has not been clinically validated. This study aimed to assess the performance of the Nanjing criteria for PA-HSOS.METHODS:
Data obtained from consecutive patients in multiple hospitals, which included 86 PA-HSOS patients and 327 patients with other liver diseases, were retrospectively analyzed. Then, the diagnostic performance of the Nanjing criteria and simplified Nanjing criteria were evaluated and validated. The study is registered in www.chictr.org.cn (ID ChiCTR1900020784).RESULTS:
The Nanjing criteria have a sensitivity and specificity of 95.35% and 100%, respectively, while the simplified Nanjing criteria have a sensitivity and specificity of 96.51% and 96.33%, respectively, for the diagnosis of PA-HSOS. Notably, a proportion of patients with Budd-Chiari syndrome (11/49) was misdiagnosed as PA-HSOS on the basis of the simplified Nanjing criteria, and this was mainly due to the overlapping features in the enhanced computed tomography/magnetic resonance imaging examinations. Furthermore, most of these patients (10/11) had occlusion or thrombosis of the hepatic vein, and communicating vessels in the liver were found in 8/11 patients, which were absent in PA-HSOS patients.CONCLUSIONS:
The Nanjing criteria and simplified Nanjing criteria exhibit excellent performance in diagnosing PA-HSOS. Thus, both could be valuable diagnostic tools in clinical practice.
