Liver/spleen volume ratio as a predictor of prognosis in primary biliary cirrhosis.
ABSTRACT The course of primary biliary cirrhosis (PBC) is determined by clinical symptoms and histological findings. The present study examined the prognostic importance of imaging parameters in PBC.
The volumes of the liver and spleen of patients with PBC were assessed by computed tomography (CT). The volume ratio of liver to spleen (LV/SV ratio) was evaluated and used for further analyses.
The prognosis was significantly poorer in PBC patients with a low, rather than high, LV/SV ratio. The Cox proportional hazard regression model showed that the serum bilirubin level and the LV/SV ratio could predict the prognosis of PBC patients. In addition, the LV/SV ratio was significantly lower in patients who developed symptoms (s-PBC) than in those who remained asymptomatic (a-PBC) during the observation period.
The LV/SV ratio is of prognostic importance in patients with PBC.

ABSTRACT: To study the liver and spleen volume variations in hepatic fibrosis patients at different histopathological stages. Multidetector computed tomography (MDCT) scan was performed in 85 hepatic fibrosis patients. Liver volume (LV) and spleen volume (SV) were measured. Fifteen healthy individuals served as a control group (S0). The patients were divided into stage 1 (S1) group (n = 34), stage 2 (S2) group (n = 25), stage 3 (S3) group (n = 16), and stage 4 (S4) group (n = 10) according to their histopathological stage of liver fibrosis. The LV and standard LV(SLV)had a tendency to increase with the severity of fibrosis, but no statistical difference was observed in the 5 groups (LV: F = 0.245, P = 0.912; SLV: F = 1.902, P = 0.116). The SV was gradually increased with the severity of fibrosis, and a statistically significant difference in SV was observed among the 5 groups (P < 0.01). The LV/SV ratio and SLV/SV ratio were gradually decreased with the aggravation of hepatic fibrosis, and statistically significant differences in both LV/SV and SLV/SV were found among the 5 groups (P < 0.01). The absence of obvious LV reduction in patients with chronic liver disease may be a morphological index of patients without liver cirrhosis. The SV is related to the severity of fibrosis, and the spleen of patients with advanced fibrosis is enlarged evidently. The LV/SV ratio and SLV/SV ratio are of a significant clinical value in the diagnosis of advanced liver fibrosis.World Journal of Gastroenterology 07/2009; 15(26):3298-302. · 2.43 Impact Factor

ABSTRACT: The diagnostic criteria for primary biliary cirrhosis (PBC) in Japan were revised in 2004. The prevalence and prognosis of PBC using the revised criteria have not been reported. This study investigated the prevalence and prognosis of "newly-diagnosed" symptomatic-PBC (ns-PBC), which was defined as asymptomatic PBC (a-PBC) in Japan until 2004. The clinical features and the prognosis of 207 patients with PBC were retrospectively investigated according to clinical stage. The prevalence of ns-PBC was 3.4% and 9.7%, at the time of diagnosis and final evaluation, respectively. The prognosis of ns-PBC was poorer than a-PBC. A total of 7.2% of the patients with a-PBC progressed to ns-PBC during the observation period. These patients had a poorer prognosis than patients who remained asymptomatic. Approximately 10% of the PBC patients presented with signs of portal hypertension as an initial symptom. The signs of portal hypertension should therefore be carefully investigated in patients with PBC at the time of diagnosis and during the observation.Internal Medicine 01/2010; 49(12):1073-8.

ABSTRACT: To study the correlation of liver and spleen volume with the degree of liver fibrosis and cirrhosis induced by hepatitis B virus infection. 128 participants who had undergone liver and spleen volumetry were enrolled. The control group consisted of 41 participants who were potential living liver donors. The liver fibrosis group consisted of 63 histologically proved liver fibrosis patients who were further divided into two subgroups: 44 patients with slight liver fibrosis, and 19 patients with advanced liver fibrosis. The liver cirrhosis group consisted of 24 patients. The following parameters were determined by multi-detector spiral computed tomography (MSCT) examination: total liver volume (TLV), right liver lobe volume (RV), left lateral liver segment volume (LLV), left medial liver segment volume (LMV), caudate lobe volume (CV), and spleen volume (SV). The ratios of CV to TLV (C/T), RV to TLV (R/T), LLV to TLV (LL/T), LMV to TLV (LM/T), and SV to TLV (S/T) were calculated. TLV, RV, LMV tended to decrease and SV, C/T, S/T tended to increase gradually with the increased degree of fibrosis. C/T >or= 3.34% and S/T >or= 47.36% were identified as the cut-off values of fibrosis >or=F3 (advanced liver fibrosis) and cirrhosis, respectively. Their sensitivities were 68.4% and 87.5% and their specificities were 59.1% and 89.5%, respectively. Variations in liver and spleen volume correlated with the degree of liver fibrosis and cirrhosis and could be used in the non-invasive follow-up of the development of liver fibrosis.Journal of Digestive Diseases 08/2010; 11(4):215-23.
