Tacrolimus and mycophenolate mofetil after nonmyeloablative matched-sibling donor allogeneic stem-cell transplantations conditioned with fludarabine and low-dose total body irradiation.

We evaluated tacrolimus/mycophenolate mofetil (MMF) for graft-versus-host disease (GVHD) prophylaxis after a nonmyeloablative stem cell transplantation (NST) from a matched sibling donor (MSD). Thirty-two patients (median age, 57 years) with advanced hematologic malignancies, who were poor candidates for a conventional myeloablative transplantation, received fludarabine (30 mg/m(2), day -4 to day -2), total-body irradiation (TBI) (200 cGy, day 0), infusion of donor peripheral blood progenitor cells (day 0), oral tacrolimus 0.06 mg/kg twice daily (from day 3), and oral MMF at 15 mg/kg twice daily (days 0-+27). Tacrolimus was tapered from day +100 to day +180 in those patients with indolent malignancies (n = 25), and from day +35 to day +56 in those with aggressive tumors (n = 7). Regimen toxicities and myelosuppression were mild, allowing 75% of patients to have entirely outpatient transplantations. One patient (3%) experienced a nonfatal graft rejection. Rates of grades II-IV and III-IV acute GVHD were 15.6% and 3%, respectively. Acute GVHD was diagnosed at median day +78 (range, days +31-+84). Extensive chronic GVHD was observed in 10 of 24 evaluable patients (41.6%) at a median onset of day +198 (range, days +128-+277), either spontaneously (n = 5) or elicited after tumor progression (n = 5). Five patients experienced transplantation-related mortality (TRM) (15.6%) from either acute GVHD-related multiorgan failure (MOF) (n = 3) or infectious complications (n = 2). At median follow-up of 19 months (range, 2-41 months), the overall survival, progression-free survival, and disease-free survival rates are 62.5%, 50%, and 40%, respectively. In conclusion, the use of tacrolimus/MMF after MSD NST is associated with encouraging rates of GVHD control.     

VIOLENT BEHAVIOUR IN PYSCHIATRIC INPATIENTS

A study of violent behaviour among psychiatric inpatients in a large general hospital is presented. Over the study period of one year a total of 36 incidents of violence involving 26 patients were recorded. Schizophrenia was the most common diagnosis among assailants. Fellow patients were the main victims. Incidence of serious violence was low. Most incidents occurred in the night hours, from inmates of acute wards and mostly without any provocation.KEY WORDS: Violent behaviour, Psychiatric patients     

Serum lipid response to a high-caloric, high-fat diet in agricultural workers during 12 months.

The effect of a gluttony diet in healthy subjects was studied over an observation period of 12 months. Twenty-six agricultural workers, all of them Yemenite Jews, received a high-caloric, high-fat diet, and the changes in serum cholesterol (CH), high-density-lipoprotein-cholesterol, triglycerides, and body weight were assessed. Yemenite Jews as a group are characterized by low serum CH levels and by a low incidence of coronary artery disease. For a period of 7 months the subjects received a diet of 4553 cal/day, more than double their original "Yemenite diet". After this time they resumed their customary low-caloric diet for 3 months, and thereafter for another 2 months they continued with the high-caloric food regimen. The high-caloric, high-fat diet resulted in the expected increase of serum CH. A similar increase of high-density lipoprotein-CH was found. Serum triglyceride levels changed inversely to those of CH. It is suggested that the altered relation of calories derived from carbohydrates to those derived from fats brought about the decrease of triglycerides, and this irrespective of the increased intake of carbohydrates and fats. The rather small gain of body weight over the trial period--despite the doubled caloric intake--is similar to other studies that showed that the ability of normal individuals to gain weight through overeating varies considerably.     

Dose-intense chemotherapy every 2 weeks with dose-intense cyclophosphamide, doxorubicin, vincristine, and prednisone may improve survival in intermediate- and high-grade lymphoma: a phase II study of the Southwest Oncology Group (SWOG 9349).

PURPOSE: To test the hypothesis that therapy of intermediate- and high-grade (excluding Burkitt lymphoblastic) lymphoma with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) could be safely dose-intensified with routine filgrastim support. PATIENTS AND METHODS: Eligible patients were those who were previously untreated and who had either bulky stage II, or stage III or IV lymphoma with working formulation histology D, E, F, G, H, or J; performance status < or = 2; and acceptable end organ function. No upper age limit was specified. Therapy was dose-intensified CHOP (CHOP-DI) with filgrastim support. Each course was repeated every 14 days for six planned courses. RESULTS: Eighty-eight eligible patients were treated with CHOP-DI and had a median follow-up of 5.1 years on this phase II study, designated Southwest Oncology Group (SWOG) 9349. The progression-free survival was 51% at 2 years and 41% at 5 years. The overall survival was 60% at 5 years. Three fatal treatment-related events occurred. One patient with myelodysplastic syndrome was reported. CONCLUSION: Treatment with CHOP-DI can be safely administered in the cooperative group setting and results in improved survival. Estimated overall survival at 5 years was 14% better than that of patients treated with standard-dose CHOP in an earlier SWOG study, although progression-free survival of 60% at 2 years-the prespecified end point-was not achieved. CHOP-DI, given every 2 weeks at escalated doses, is a strategy that should be tested in a future randomized clinical trial in lymphoma.     

Early introduction of allergenic foods for the prevention of food allergy from an Asian perspective—An Asia Pacific Association of Pediatric Allergy,Respirology & Immunology (APAPARI) consensus statement

Emerging evidence for the early introduction of allergenic foods for the prevention of food allergies, such as peanut allergy in Western populations, has led to the recent publication of guidelines in the USA and Europe recommending early peanut introduction for high‐risk infants with severe eczema or egg allergy. Peanut allergy is, however, much less prevalent in Asia compared to the West. Varying patterns of food allergy are seen even within Asian countries—such as a predominance of wheat allergy in Japan and Thailand and shellfish allergy in Singapore and the Philippines. Customs and traditions, such as diet and infant feeding practices, also differ between Asian populations. Hence, there are unique challenges in adapting guidelines on early allergenic food introduction to the Asian setting. In this paper, we review the evidence and discuss the possible approaches to guide the timely introduction of allergenic food in high‐risk infants in Asia.     

Allogeneic marrow transplantation in patients with chronic myeloid leukemia in the chronic phase: a randomized trial of two irradiation regimens

A randomized trial was performed to compare two regimens of total body irradiation in patients with chronic myeloid leukemia treated by allogeneic marrow transplantation while in the chronic phase. All patients received cyclophosphamide 120 mg/kg followed by total body irradiation and marrow from HLA-identical siblings. Cyclosporine and methotrexate were used for prophylaxis against acute graft-versus-host disease. Fifty-seven patients were randomized to receive 2.0 Gy fractions of irradiation daily for 6 days and 59 were randomized to receive 2.25 Gy fractions daily for 7 days. The probabilities of relapse at 4 years were 0.25 for the 12.0 Gy group and 0.00 for the 15.75 Gy group (P = .008). The actuarial probabilities of survival and relapse-free survival at 4 years were 0.60 and 0.58 among the patients who received 12.0 Gy compared with 0.66 and 0.66 for those who received 15.75 Gy. The 4-year probabilities of transplant-related mortality were 0.24 and 0.34 respectively (P = .13) while the probability of moderate to severe acute graft-versus-host disease was 0.33 for the 12.0 Gy group and 0.44 for the 15.75 Gy group (P = .15). The lower relapse probability in the patients receiving the higher dose of total body irradiation did not result in improved survival because mortality from causes other than relapse was increased.     

Autologous transplantation followed closely by reduced-intensity allogeneic transplantation as consolidative immunotherapy in advanced lymphoma patients: a feasibility study

We report outcomes in advanced lymphoma patients (n = 32) who enrolled in a trial of prospectively planned combined autologous/reduced-intensity transplantation (RIT) (n = 25) or who received RIT shortly after prior autografting because of high relapse risk or progressive disease (n = 7). Nine patients on the autologous/RIT transplant protocol did not proceed to planned RIT because of patient choice (n = 4), disease progression (n = 3), toxicity (n = 1), or no adequate donor (n = 1). Among the 23 other patients, RIT was started a median of 59 days (range 31-123) after autologous transplant. Fifteen patients had related donors, five patients had unrelated donors, and three patients had cord blood donors. Among all patients completing RIT, the median overall survival time was 385 days (95% CI 272-792), and the median relapse-free survival time was 157 days (95% CI 119-385). At the time of reporting, six patients (26%) remain alive and three patients (13%) remain alive without relapse. The 100-day transplant-related mortality (TRM) was 9% among all patients and was 0% among matched sibling donors. Overall TRM was 43%. Tandem transplant is feasible in advanced lymphoma with low early TRM. However, practical challenges associated with the strategy were significant and high levels of late TRM due to graft-versus-host disease and infections suggest that modifications of the procedure will be needed to improve outcomes and patient retention.
