Diagnosis of hepatic steatosis and steatohepatitis in people with new-onset type 2 diabetes: a multidisciplinary approach.

AIMS: Non-Alcoholic-Fatty-Liver-Disease (NAFLD) is the most common cause of chronic liver disease in Western countries; closely linked to obesity and type 2 diabetes (T2DM), it is an additional cardiovascular risk factor. The aim of this study is to investigate the prevalence of NAFLD at T2DM onset. METHODS: 122 newly diagnosed T2DM patients were enroled; NAFLD was diagnosed using ultrasound and fibrosis risk calculated with an FIB4-score. Intermediate and high-risk patients were referred to a hepatologist and underwent transient elastography (TE). RESULTS: At T2DM diagnosis, 25% of patients were overweight, 47% were obese; ultrasound steatosis was present in 79% of patients; the average FIB-4 score was 1.4 (0.7). The NAFLD population was characterised by higher presence of obesity (60%, p 0.06); hypertension (56%, p 0.00); AST (26.3 (23.6) UI/L; p 0.00); ALT (49.3(41.0) UI/L p 0.00); FIB-4 score (1.6 (0.8); p 0.00). Among patients referred to a hepatologist, at TE, 65% had severe steatosis, 22% significant fibrosis and 25% advanced fibrosis. CONCLUSION: This is the first proposal of a NAFLD screening model at T2DM diagnosis. The high prevalence of fibrosis found at the early stage T2DM confirms the compelling need for early management of NAFLD through cost-effective screening and long-term monitoring algorithms.

Postremission chemotherapy in adult acute non-lymphoblastic leukaemia including intensive or non-intensive consolidation therapy.

From October 1983 to December 1988, 84 consecutive adult patients with acute non-lymphoblastic leukaemia (ANLL; median age = 51 yr) were uniformly treated to induce remission (CR) with intravenous vincristine and cytarabine sequentially followed by daunomycin and infusion cytarabine. From October 1983 to December 1985 consolidation was non-intensive (2 courses with the same drugs used for induction) (protocol ANLL83: 27 patients, median age = 45). From January 1986 to December 1988 consolidation was intensive (4 courses of vincristine and cytarabine sequentially followed by etoposide plus thioguanine or amsacrine) (protocol ANLL86: 57 patients, median age = 57). Excluding early deaths, the CR rate was 71.6%. Median CR, responsive patient survival and overall survival were 11.1, 15.3 and 8.5 mo, respectively. For protocol ANLL83 and ANLL86, median CR was 8.7 and 13.2 mo (P less than 0.05) and median survival was 13.1 and 16.9 mo (P less than 0.05) for responders and 8.0 and 9.2 mo (P not significant) for all patients. Intensive consolidation including drugs not previously used for induction seems to prolong CR duration and responder survival in adult ANLL.

Prognostic significance of DNA content in large bowel carcinoma: a retrospective flow cytometric study.

Flow cytometric (FCM) determination of DNA content was performed on surgical specimens from 44 patients with previously untreated colonic carcinoma. For each tumor, cell suspensions were prepared from 2-4 40-microns thick sections obtained from formalin-fixed and paraffin embedded tissue samples. Aneuploidy was found in 47.2% of all the tumors and the aneuploid clone had a median DNA index of 1.49 (range: 1.24-1.93). Aneuploidy was found in 26.7% of highly differentiated tumors (WHO histologic classification), in 53.8% of moderately differentiated tumors and in 100% of poorly differentiated tumors (P = 0.04). The 33.3% of stages 1 + 2 (TNM) and the 70.6% of stages 3 + 4 tumors were aneuploid (P = 0.002). Median survival from surgery was 46.4 months for all patients. It was 18.8 months for patients with aneuploid tumors and 85.7 months for those with diploid tumors (P = 0.0002). FCM determination of DNA in colon carcinomas can easily be performed on archival histological material and provides prognostic information.

Prognostic parameters in myelodysplastic syndromes: a multiple regression analysis.

The influence on survival of 21 basic clinical and hematologic parameters was evaluated in 72 patients with previously untreated myelodysplastic syndromes (MDS). Only five parameters were significant by both survival curves and multiple regression analyses: hemoglobin level, bone marrow (BM) cellularity (estimated from trephine BM biopsies), BM blast percentage, age and BM erythro/myeloid (E/M) ratio. Using these parameters, multiple regression analysis enabled us to predict 34% of the survival of all MDS patients (p less than 0.002), 38% of that of patients who had stable disease (p less than 0.04) and over 80% of that of patients who developed acute leukemia (p less than 0.02). High BM cellularity was the most predictive factor for the development of leukemia. No factor was predictive for patients who died of cytopenic or other complications.

Flow cytometric DNA index in the prognosis of colorectal cancer.

The authors investigated the relationship between flow cytometric DNA index (DI, defined as the ratio of the DNA content of malignant cells to that of normal cells) and other prognostic factors (grade and stage, anatomical site, age and sex) with the survival of 115 patients with colorectal cancer. Multiple biopsy specimens from 62 patients were taken during colonoscopy before surgery. Additional samples from 53 patients were obtained from paraffin-embedded material. All patients were treated with surgery only. Fresh-frozen material gave higher incidence of DNA aneuploidy than paraffin-embedded material (79% versus 41%). The patients with DNA diploid tumors (DI = 1) had a better overall survival than those with DNA aneuploid tumors (DI = 1). Among DNA aneuploid tumors, those with DI greater than 1.2 (excluding DI = 2) were worse than those with DI = 1.2 (excluding DI = 1) and DI = 2. Cox's regression analysis showed that pathologic stage was more important for prognosis than DNA index, whereas age, sex, histologic grade, and anatomic site were removed from the analysis as not relevant for prognosis. Relative risk of death (RR), in reference to patients with DI = 1 and Stages A + B (RR = 1), were RR = 1.8 for patients with carcinomas with Stage C. RR = 2.7 for patients with carcinomas with DNA near-diploid and DNA tetraploid tumors. RR = 3.5 for those with DI greater than 1.2 (excluding DI = 2), and RR = 8.0 for those with Stage D. These data indicate that flow cytometrically evaluated DI values have a relevant independent power for predicting the clinical outcome of colorectal cancer patients.
