Schistosomiasis and hepatitis B virus (HBV) infection are very common in Brazil but the interrelationships between the two infections are poorly understood. We have undertaken a detailed serological study of the prevalence of HBV markers in 189 Brazilian patients with chronic schistosomiasis mansoni, 46 with hepatointestinal (HIS) and 143 with hepatosplenic (HSS) schistosomiasis, 12 of the latter having decompensated liver disease (HSSD), and in 50 control patients. Sera were tested for HBsAg, anti-e, anti-HBc, anti-HBs and HBV-DNA. Eighty-three (44%) of the 189 schistosoma patients had at least one marker of HBV infection, 18 of whom (10%) were seropositive for HBsAg. All the controls were HBsAg negative, but ten (20%) had anti-HBc and anti-HBs. There was no significant difference in the frequency of these markers between HIS (14/46, 30.4%), HSSC (43/131, 34.5%), and the controls. Among the HBsAg-positive patients, one had HIS (HBV-DNA negative), seven had HSSC (one HBV-DNA positive) and ten had HSSD (six HBV-DNA positive), a significant association of HBV carriage with HSSD (P << 0.001). Mean (+/- SD) ALT values were significantly (P < 0.001) higher in HBsAg-positive HSSD patients (70.7 +/- 18 IU/liter) than in those with HSSC (29.5 +/- 15 IU/liter). Liver biopsies were performed in 12 HBsAg-positive patients (one with HIS, three with HSSC, and eight with HSSD) and in 50 HBsAg-negative HSSC patients. Seven of the eight HSSD patients had chronic active hepatitis with cirrhosis, and one had inactive cirrhosis. All three patients with HSSC and the one with HIS had chronic persistent hepatitis, with periportal fibrosis in three.(ABSTRACT TRUNCATED AT 250 WORDS)

Platinum based combination regimens are first-line treatment option in treatment of non-small cell lung cancer (NSCLC) but the clinical utility has been limited because of their toxicities. Many reports indicated that patients with tumors can benefit from adjuvant chemotherapy drugs. The aim of this study was to confirm adjuvant chemotherapy of HSS with docetaxel plus cisplatin (DP) against NSCLC by evaluating antitumor activity and attenuated effect. In vivo SPC-A-1 xenograft model was established to evaluate antitumor activity and toxicity of HSS along or combination with DP. Evaluation indexes include the relative tumor proliferation rate, tumor growth inhibition rate, body weight, food consumption, hematological and biochemical analysis. HSS treatment showed inhibited tumor growth and increased tumor inhibition of DP treatment at doses of 250 mg/kg and 500 mg/kg. No significant toxicity was found in HSS-treated mice, but significant toxicity was found in DP-treated mice. HSS combination with DP could reduce toxicity of DP treatment by improving body weight and food consumption, and increasing the number of WBC and PLT, decreasing the level of ALT, AST and BUN. HSS combined with DP treatment has additive effect which contributes to enhance tumor growth inhibition of DP treatment and attenuated effect which contributes to reduce toxicity of DP treatment. These findings indicate potential benefit for use of HSS adjuvant chemotherapy for NSCLC treatment.
