A 75-year-old female patient with liver cirrhosis and hepatitis C was treated with direct-acting antivirals (DAA) (Sofosbuvir+Ledipasvir). The hepatitis C virus (HCV) -RNA level decreased to negative 4 weeks after the start of the treatment. Six weeks later, she developed ascites and showed declining hepatic spare ability. Accordingly, DAA treatment was stopped. She was started on furosemide 20mg/day and spironolactone 50mg/day. After 7 days, she started taking tolvaptan 7.5mg/day because furosemide and spironolactone proved to be ineffective. This new regimen resolved the ascites. The HCV-RNA level remained negative, although DAA was not restarted. Finally, she achieved a sustained virological response (SVR). The hepatic spare ability at the time of SVR recovered than that at the time of DAA treatment.

A 59-year-old man had been admitted to our hospital because of general malaise and abdominal fullness caused by massive ascites. He was diagnosed with alcoholic liver cirrhosis. Following the removal of ascites, he was referred to our department because of hematochezia. Emergent colonoscopy revealed the rupture of ascending colonic varices. Endoscopic variceal sclerotherapy using topical skin adhesive (75% Histoacryl) was performed to treat the colonic varices, which proved to be an effective treatment. Enhanced computerized tomography performed 5 days after the treatment of ascending colonic varices showed complete obstruction of the ileocolic varices without complication. It is important to consider the possibility of ectopic varices when a patient with liver cirrhosis reports bloody stool.

We investigated the relation between gastric mucosal lesions and substance P (SP) in 64 patients with rheumatoid arthritis (RA) taking nonsteroidal antiinflammatory drugs (NSAIDs). In these patients, the incidence of gastric mucosal lesions was as high as 53.1%. Serum SP levels were significantly higher in patients with gastric mucosal lesions than in those without gastric lesions. Erythrocyte sedimentation rate, serum C-reactive protein and rheumatoid factor (RF) levels were also higher in patients with gastric mucosal lesions. A positive correlation between serum SP and RF levels was found in patients with RA. Experimental gastric mucosal lesions induced by an oral administration of indomethacin in rats were significantly enhanced by an additional intraperitoneal injection of SP. From these observations, it is suggested that, in addition to the effect of NSAIDs, SP elevation in blood has a role in the development of gastric mucosal lesion in patients with RA.

Antibodies against hepatitis C (HCV) in 512 patients were measured by an enzyme immunoassay (Ortho-HCV ELISA). The frequency of anti-HCV was 80%, 86%, 85% in nonB (NB) chronic hepatitis (CH), cirrhosis (LC), hepatocellular carcinoma (HCC), respectively; 70%, 90% in alcoholic (AL) LC, HCC; 15%, 33%, 58% in hepatitis B (HB) CH, LC, HCC, respectively. Anti-HCV positive cirrhotics had a shorter survival time and earlier development of HCC than anti-HCV negative cirrhotics. The findings suggest that HCV is a major cause of NB chronic liver diseases and may play a pathogenetic role in AL and HB liver diseases.
