A total of 50 patients were included in the analysis, 20(study group) had received 3.2 g/d of mesalamine starting from the day of admission in addition to the usual standard treatment, 30(control group) had received standard therapy alone. Data was retrieved from a prospective database. Our primary study endpoints were: C reactive protein mean levels over time and their variation from baseline(ΔCRP) over the first three days of treatment. Secondary end points included: mean white blood cell and neutrophile count over time, time before regaining of regular bowel movements(passing of stools), time before reintroduction of food intake, intensity of lower abdominal pain over time, analgesic consumption and length of hospital stay.RESULTS: Patients characteristics and inflammatoryparameters were similar at baseline in the two groups. The evaluation of CRP levels over time showed, in treated patients, a distinct trend towards a faster decrease compared to controls. This difference approached statistical significance on day 2(mean CRP 6.0 +/- 4.2 mg/d L and 10.0 +/- 6.7 mg/d L respectively in study group vs controls, P = 0.055). ΔCRP evaluation evidenced a significantly greater increment of this inflammatory marker in the control group on day 1(P = 0.03). A similar trend towards a faster resolution of inflammation was observed evaluating the total white blood cell count. Neutrophile levels were significantly lower in treated patients on day 2 and on day 3(P < 0.05 for both comparisons). Mesalamine administration was also associated with an earlier reintroduction of food intake(median 1.5 d and 3 d, study group vs controls respectively, P < 0.001) and with a shorter hospital stay(median 5 d and 5.5 d, study group vs controls respectively, P = 0.03).CONCLUSION: Despite its limitations, this study suggests that mesalamine may allow for a faster recovery and for a reduction of inflammatory response in acute uncomplicated diverticulitis.展开更多

Surgery is still the major prognostic factor for gastric cancer. Patients who could not be resected have a poor prognosis with survival ranging from 3 to 11 months. There is evidence that surgical operations can cause a variety of immunological disturbances in man both in vivo and in vitro. The postoperative changes in the systemic immune response are proportional to the degree of surgical trauma leading to a generalized state of immunosuppression, which is implicated in the development of septic complications and provided a “fertile soil” for tumor cell metastasis. Immunotherapy may be a potentially promising alternative strategy for gastric cancer. In early clinical trials, systemic immunotherapy included both active vaccination directed against defined tumor-associated antigens expressed in gastric carcinoma cells and passive administration of IL-2 with some evidence of regression of metastatic gastric cancer. Other studies have applied immunotherapy in the adjuvant setting with equally promising results. For example, OK-432, a streptococcal preparation, demonstrated marginal improvement in survival for patients with stage III gastric cancer and a meta-analysis of centrally randomized controlled clinical trials indicated a significant survival benefit with combination OK-432 and chemotherapy compared to chemotherapy alone (p 0.05). Additional data suggesting a biological and clinical benefit of subcutaneous, preoperative administration of low-dose IL-2 in colon cancer encouraged us to evaluate low-dose IL-2 therapy in the neoadjuvant setting for patients with gastric adenocarcinoma who undergo surgery and to evaluate its effects on systemic and tumor infiltrating lymphocyte numbers. We also sought to determine if neoadjuvant low-dose IL-2 could influence the clinical outcome for patients undergoing gastric resection for cancer. We report the biological, histological and clinical results with the full accrual of patients and a median follow-up of 51 months.展开更多
