Immunosuppressive therapy in chronic active hepatitis (CAH). A multicentric retrospective study on 867 patients. A report from a study group for CAH of the Italian Association for the study of the liver.

We retrospectively reviewed the clinical, biochemical and histological features of 867 patients with biopsy-proven CAH observed in 12 Italian Liver Units for at least one year. Either HBsAg positive or HBsAg negative patients (473 and 394 patients, respectively) were left untreated, or were treated with one of the following regimens: a) prednisolone or prednisone 10 to 30 mg daily, referred to as Steroids; b) azathioprine 50 to 100 mg daily; c) prednisolone or prednisone 10 to 20 mg daily associated with azathioprine 50 to 100 mg daily, referred to as Combination. The outcome was evaluated on the basis of clinical, biochemical and histological parameters. Among the 473 patients with HBsAg positive CAH those treated with combination, as compared to those untreated, more frequently, improved (P less than 0.001), and less frequently deteriorated (P less than 0.001). Under Steroids or Azathioprine improvement was more frequent than in untreated patients, but deterioration was not prevented. The results were similar among the 394 HBsAg negative patients. The data indicate that combination is effective in treating either HBsAg positive CAH or HBsAg negative CAH.

Etiological, clinical and laboratory data of post-transfusion hepatitis: a retrospective study of 379 cases from 53 Italian hospitals.

Among the 8,604 cases of acute viral hepatitis hospitalized during 1982 in 53 Italian hospitals, we studied 379 cases of post-transfusion hepatitis, 262 cases which occurred after surgery and 4,576 cases with no history of parenteral exposure. The etiological agents of post-transfusion hepatitis were NANB viruses in 57.8%, HBV in 39.0% and HAV in 3.2% of the cases. CMV and EBV accounted for less than 1.5% of the post-transfusion hepatitis cases. HBV was the main etiological agent (62.2% of the cases) in the post-surgical hepatitis group, where HAV accounted for only 6.1% of the cases. In contrast, in the group with no history of parenteral exposure, hepatitis A was most frequent. Percentages of patients with history of transfusion or surgery were always higher in type B and NANB hepatitis than in type A, suggesting that surgery without transfusion also represents a risk of acquiring type B and NANB hepatitis. No regional differences were observed in the etiological patterns of post-transfusion hepatitis and post-surgical hepatitis. The acute phase of type B post-transfusion hepatitis was more severe than that of NANB post-transfusion hepatitis, as shown by higher serum bilirubin and ALT levels and by a higher case fatality rate.

Activity and toxicity of gemcitabine and gemcitabine + vinorelbine in advanced non-small-cell lung cancer elderly patients: Phase II data from the Multicenter Italian Lung Cancer in the Elderly Study (MILES) randomized trial.

BACKGROUND: Following the demonstration that vinorelbine improves survival and quality of life compared with best supportive care in elderly patients with advanced non-small-cell lung cancer (NSCLC), we started the three-arm prospective Multicenter Italian Lung Cancer in the Elderly Study (MILES) trial of vinorelbine, gemcitabine and gemcitabine + vinorelbine. DESIGN: Within the randomized phase 3 trial, pilot single-stage phase 2 studies were planned for gemcitabine and for gemcitabine + vinorelbine. Eligible patients are aged 70 or more, with stage IV or IIIb (with metastatic supraclavear nodes or malignant pleural effusion) NSCLC. Single-agent gemcitabine is given at 1200 mg/m(2) on days 1 and 8; in the combination, gemcitabine is given at 1000 mg/m(2) and vinorelbine at 25 mg/m(2), both on days 1 and 8, every 3 weeks. RESULTS: As planned 49 patients were enrolled in each group. Median age was 74 in both groups. Two-thirds of patients had stage IV disease. The response rate was 18.4% (95% exact CI 8.8-32.0) with both treatments. With single-agent gemcitabine main toxicities were grade 4 thrombocytopenia and grade 2 hepatic toxicity, in one patient each, and grade 2 pulmonary toxicity in two patients. With gemcitabine + vinorelbine combination there were grade 4 neutropenia and thrombocytopenia (one patient each), grade 3 anemia requiring red blood cell transfusion (two patients), and grade 4 fever in two patients. Four patients, with severe cardiac comorbidities, suffered grade 3 heart toxicity with atrial flutter or fibrillation, followed by congestive heart failure responsive to treatment. CONCLUSION: Both single-agent gemcitabine and the gemcitabine + vinorelbine combination are sufficiently active and tolerable to allow continuation of the MILES study.

Immunosuppressive therapy of HBsAg-positive chronic active hepatitis in childhood: a multicentric retrospective study on 139 patients.

We analyzed retrospectively the effect of immunosuppressive therapy in 139 children with HBsAG-positive chronic active hepatitis (CAH) observed in four liver units in Italy from 1974 to 1982. All children had been observed for at least 12 months. Of these 139 patients, 38 were treated with steroids (prednisolone or prednisone from 1 to 2 mg/kg daily), 78 with combination therapy (prednisolone or prednisone 1 mg/kg daily in combination with azathioprine, 2 mg/kg daily) and 23 were not treated. The outcome of the disease was assessed by evaluating clinical, biochemical, and histological parameters on the basis of preselected criteria. Untreated patients deteriorated more frequently than those treated with steroids (34.8% versus 13.2%, p less than 0.05) or those receiving combination therapy (34.8% versus 10.3%, p less than 0.01). Remission or improvement was observed more frequently in steroid-treated and combination-treated patients than in the untreated ones (p less than 0.001 and p less than 0.01, respectively). At the end of the study, only one untreated patient had died of liver failure. Remission was observed in about 10% of patients in the two groups of treatment, but in the untreated one, this event never occurred. Although this study is retrospective and presents some shortcomings, the data clearly indicate that steroid and combination therapy are not deleterious, and are possibly helpful, to children with HBsAg-positive CAH.(ABSTRACT TRUNCATED AT 250 WORDS)

Prognostic significance of necrosis, elastosis, fibrosis and inflammatory cell reaction in operable breast cancer.

We analyzed retrospectively the relationships and the prognostic significance of four anatomopathological features (elastosis, fibrosis, necrosis, inflammatory cell reaction) of the primary tumor in a series of 1,457 cases of infiltrating ductal carcinoma observed at our institution from January 1978 to December 1991. Necrosis, elastosis, fibrosis and inflammatory cell reaction were strongly associated among themselves (all p < 0.0001), the only exception being necrosis and elastosis. Necrosis was significantly related to tumor size (odds ratio [OR] = 5.40, p < 0.0001) and tumor grade (OR = 2.22, p < 0.0001). Univariate analysis showed that the presence of necrosis and cell reaction were significantly related to worse survival (p < 0.0001 and p = 0.03, respectively). Multivariate analysis, including the four variables plus nodal status, tumor size, grading, adjuvant therapy, age and first order interactions, revealed that greater tumor size (p < 0.0001), positive nodal status (p < 0.0001), higher histologic grade (p < 0.0001) and presence of inflammatory cell reaction (p = 0.0007) independently worsened survival. On the other hand, adjuvant therapy had a significant independent role in preventing deaths (p = 0.03). The only first-order interaction retained in the model was that between grading and cell reaction (p = 0.002). Cell reaction had a different prognostic behaviour in the groups G1-G2 and G3: in the former group, survival was worse (p = 0.0001) when the inflammatory cell reaction was present. In conclusion, we demonstrate that cell reaction is an independent prognostic factor in the G1-G2 subgroup of patients, and propose a hypothesis as to the role of cell reaction in primary breast cancer.

Splenic mucinous cystadenocarcinoma arising in heterotopic pancreatic tissue.

A mucinous cystadenocarcinoma along with remnants of normal pancreatic tissue was discovered in the spleen of a 21-year-old woman. Extensive clinical, radiological, ultrasound and computed tomography investigation revealed that the patient's pancreas and ovaries were unremarkable. We presume an origin from heterotopic pancreatic tissue for this neoplasm and present a review of the literature in this regard.

Endoscopic treatment of carpet-like adenomas of the rectum.

BACKGROUND: Transanal microsurgery, endoscopic laser photocoagulation and snare resection have all been used to treat large sessile adenomas of the rectum alternatively to a surgical approach. However, such modalities are often defective due to the carpet-like shape and the frequently large extension of the lesions. METHODS: Ten patients with carpet-like adenoma were submitted to transanal endoscopic resection by urological resectoscope. RESULTS: Complete eradication was obtained in all lesions. The mean number of treatment sessions was 3 (range, 1-5). The mean time between the first treatment and the complete eradication was 6 months (range, 1-18). The only complications were an intraoperative and an early postoperative bleeding. There was no early or late mortality related to the procedure. CONCLUSIONS: Transanal endoscopic resection by urological resectoscope appears to be a suitable therapeutic approach for sessile and carpet-like adenomas of the rectum or for pTI cancer in patients who refuse major surgery.

[The liver in patients with beta-thalassemia major. Determination of iron levels with magnetic resonance].

INTRODUCTION: We investigated the clinical usefulness of liver MRI in a large multicenter study because the control of iron concentration (LIC) is crucial in thalassemia major (TM) prognosis and conflicting results have been reported in small and heterogeneous groups of patients using Magnetic Resonance Imaging (MRI), the only very common non-invasive procedure. MATERIAL AND METHODS: One hundred and eight consecutive TM patients, selected according to a specific protocol, were included in the study. In 29 of these LIC was measured by atomic absorption spectrophotometry on liver biopsy and expressed as microgram/gr dry weight. MRI was performed with a 0.5 T superconducting unit. The ratio of the average signal intensity (SIR) of the liver to that of paraspinal muscle was calculated and expressed as a percentage. RESULTS: Mean +/- (SD) of SIR was 100 +/- 26% (test for normality: p = 0.02) and of LIC was 3677 +/- 4662 micrograms/g/dry liver (test for normality: p < 0.00001). The logit transformation of LIC (lLIC) achieved both normality of distribution of lLIC and linear regression of lLIC on SIR (t = 7.36; p < 0.00001) according to the equation: Y = -0.0136 + SIR* (0.157) = lLIC log10 (K-LIC/LIC) where K = 79.433. Thus the values of LIC are expressed by the equation LIC K/(1 + 10 y) micrograms/g/dry liver. Moreover, a mild correlation was found between SIR and AST (p = 0.01; r = -0.30), ALT (p = 0.02; r = -0.21), gamma GT (p = < 0.01; r = -0.37; r = -0.25). CONCLUSIONS: This study shows that LIC can be calculated as a function of SIR. A validation study is necessary before introducing this prediction rule in clinical practice.
