The incidence of hepatocellular carcinoma (HCC) in patients with primary biliary cirrhosis (PBC) is not well known. The aims of this study are to determine HCC incidence and survival, and to identify risk factors associated with these outcomes in patients with PBC. We collected information on 396 patients with PBC at enrollment and followed-up from 6 to 271 months. They were all negative for hepatitis B and C virus markers. HCC was detected by scanning with ultrasonography, computed tomography, or both every 4 to 6 months. Life expectancy (LE) was approximated with the declining exponential approximation of LE. A total of 14 patients developed HCC. The cumulative appearance rate of HCC in patients with advanced-stage PBC (Scheuer's stage III or IV) was significantly higher than that for patients with early-stage (stage I or II) (12.3% and 7.7% by the tenth year, respectively. P ‫؍‬ .021). Proportional hazards analysis showed 3 factors are independently associated with the development of HCC: age at the time of diagnosis, male gender, and history of blood transfusion. Age, male gender, and advanced-stage PBC were associated with survival, but HCC development was not. The disease-specific annual mortality rate was estimated to be 0.008 for women and 0.028 for men with advanced-stage PBC. In conclusion, HCC develops in old patients with advanced-stage PBC, but HCC does not affect the patients' survival. P rimary biliary cirrhosis (PBC) is a chronic liver disease of unknown etiology presenting a variety of disease spectrum from asymptomatic disease state to full-blown cirrhosis. Patients with liver cirrhosis caused by chronic infection of hepatitis C virus (HCV) or hepatitis B virus (HBV) are at high risk of hepatocellular carcinoma (HCC); however, it is not known whether the HCC incidence is high in patients with PBC. Although there are 9 studies about HCC incidence in PBC, the results are not consistent. 1-9 Some studies 3,4 show that patients with PBC have no excess risk of developing HCC and others [5][6][7][8][9] show that the incidence of HCC is high in those patients. An Italian study indicated that HCC has a relatively high prevalence in PBC and HCV superinfection may play an important part in favoring HCC. 7 Even though without HBV or HCV infection, a study conducted in UK showed 5.9% of patients with PBC in precirrhotic or cirrhotic stage had developed HCC. 6 The authors of this large-scale cohort study concluded that men with advanced-stage PBC have a higher risk of developing HCC. A recent retrospective study in the Mayo Clinic also reported that patients with PBC 8 are at high risk of hepatobiliary malignancies but the authors did not mention risk factors for HCC development.The aims of the present study are to analyze the survival of patients with PBC, to quantify the incidence at which they develop HCC, and to identify HCC risk factors. In addition, we determined whether HCC affected the survival of patients with PBC. Therefore, we tested 2 hypotheses: (1) that the patients with advanced-stage PBC sur...

In Japan, bezafibrate (BF) is a second‐line agent for primary biliary cholangitis (PBC) that is refractory to ursodeoxycholic acid (UDCA) treatment. From a retrospective cohort (n = 873) from the Japan PBC Study Group, we enrolled 118 patients who had received UDCA monotherapy for at least 1 year followed by combination therapy with UDCA+BF for at least 1 year. GLOBE and UK‐PBC scores after UDCA monotherapy (i.e., immediately before UDCA+BF combination therapy) were compared with those after 1 year of UDCA+BF combination therapy. The real outcomes of enrolled patients estimated by Kaplan–Meier analysis were compared with the predicted outcomes calculated using GLOBE and UK‐PBC scores. In addition, the hazard ratio of BF treatment was calculated using propensity score analysis. The mean GLOBE score before the combination therapy was 0.504 ± 0.080, which improved significantly to 0.115 ± 0.085 (P < 0.0001) after 1 year of combination therapy. The real liver transplant‐free survival of enrolled patients was significantly better than that predicted by GLOBE score before introducing BF. Combination therapy did not significantly improve the real rates of liver transplantation or liver‐related death compared with those predicted by UK‐PBC risk score before introducing BF, but the predicted risk was significantly reduced by the addition of BF (P < 0.0001). Cox regression analysis with inverse probability of treatment weighting showed that the addition of BF significantly reduced the hazard of liver transplant or liver‐related death in patients who, after 1 year of UDCA monotherapy, had normal serum bilirubin (adjusted hazard ratio 0.09, 95% confidence interval 0.01‐0.60, P = 0.013). Conclusion: Addition of BF to UDCA monotherapy improves not only GLOBE and UK‐PBC scores but also the long‐term prognosis of PBC patients, especially those with early‐stage PBC.

Summary. Angiogenesis is a crucial process in the progression of multiple myeloma (MM). Vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) are multifunctional cytokines that potently stimulate angiogenesis including tumour neovascularization. Serum levels of VEGF and HGF were measured in 52 patients with MM by enzyme‐linked immunosorbent assay (ELISA). Serum levels of VEGF and HGF were elevated in MM patients compared with healthy controls (VEGF: mean 0·31 ng/ml and 0·08 ng/ml respectively, P < 0·01; HGF: mean 2·17 ng/ml and 0·45 ng/ml, respectively, P < 0·001). In serial samples taken after chemotherapy, serum VEGF and HGF levels were correlated with M‐protein levels. Serum levels of VEGF were higher in patients with extramedullary plasmacytomas than in patients without them (P < 0·05). They were also significantly higher in a group of patients who showed poor response to chemotherapy (P < 0·01). Serum levels of HGF were higher in patients with complications such as anaemia, hypercalcaemia and amyloidosis than in patients without these complications (P < 0·01, P < 0·05, P < 0·05 respectively). Both serum VEGF and HGF levels were significant predictors of mortality (P = 0·01, P = 0·02, respectively, log‐rank test). The present study demonstrated that serum levels of VEGF and HGF are significantly elevated and dependent on the severity of MM, suggesting that measurement of VEGF and HGF may be useful for assessing disease progression and for predicting the response to chemotherapy in MM patients.

One hundred and sixty-one children with idiopathic GH deficiency who received GH treatment were followed until they reached their final height. Final height was found to be influenced by gonadal function. In 108 patients who had spontaneous puberty (91 boys and 17 girls; group A), the mean final height was 151.8 +/- 6.6 (+/- SD) cm in boys and 141.7 +/- 7.4 cm in girls. In 29 patients with combined GH and gonadotropin deficiency (23 boys and 6 girls; group C), whose pubertal development was induced artificially at age 19.5 +/- 2.1 yr in the boys and 18.6 +/- 1.8 yr in the girls, the mean final height was 163.7 +/- 3.9 cm in boys and 151.0 +/- 5.1 cm in girls. The differences in final height between groups A and C were significant in both boys and girls. The shorter final height in group A was caused by the shorter pubertal duration and smaller pubertal height gain than those in normal children. In 24 patients (17 boys and 7 girls; group B) who developed early signs of puberty, gonadal suppression therapy with cyproterone acetate and/or medroxyprogesterone acetate was given. The mean SD score of the final height in these 24 patients was -2.1 +/- 0.6, significantly higher than that in group A. This beneficial effect of gonadal suppression treatment on final height was caused by increases in the duration of puberty and the pubertal height gain.
