A high-dose pulse steroid regimen for controlling active chronic graft-versus-host disease

AbstractCorticosteroids remain essential for controlling active chronic graft-versus-host disease (cGVHD). However, the optimum dose and administration schedule is unknown. We have reviewed our results in 61 patients with severe refractory cGVHD who were treated with a high-dose pulse steroid regimen (PS) consisting of methylprednisolone at 10 mg/kg per day for 4 consecutive days, with subsequent tapering doses. After 4 days, all patients received a course of additional immunosuppressive therapy. The median age of the 56 patients who were evaluable for response was 32 years (range, 0.2-57 years). Patients had failed a median of 2 (range, 1-5) treatments prior to the PS. The median follow-up for 45 surviving patients after PS was 1.5 years. The probability of survival at 1 year and 2 years after PS was 88% (95% confidence interval [CI], 76%-95%) and 81% (95% CI, 65%-91%), respectively. Twenty-seven patients (48%) showed a major response to PS with substantial improvement of cGVHD manifestations, including softening of the skin, increased range of motion, and improved performance status; 15 patients (27%) showed a minor response, defined as improvement in some but not all symptoms of cGVHD. Of the 42 responders, 21 (50%) had progression of their cGVHD afterwards. The median time to progression was 1.9 years. The probability of progression at 1 and 2 years after PS was 36% (95% CI, 23%-53%) and 54% (95% CI, 38%-71%), respectively. The probability of progression at 1 year was 25% (95% CI, 12%-47%) and 55% (95% CI, 32%-81%) for patients who had major and minor response, respectively (hazard ratio, 2.13). Ten of the 42 responders (24%) were able to discontinue all systemic immunosuppressive treatments. The probability of discontinuation at 1 and 2 years after PS was 9% (95% CI, 3%-25%) and 27% (95% CI, 15%-48%), respectively. The treatment was well tolerated with no serious adverse events. Our results suggest that PS is a well-tolerated regimen for achieving rapid clinical response in the majority of patients with cGVHD who failed on multiple previous therapies. Further studies are warranted to maintain the efficacy of this regimen by combining with new active agents in cGVHD.Biol Blood Marrow Transplant 2001;7(9):495-502

Gastrointestinal involvement in chronic graft-versus-host disease: A clinicopathologic study

AbstractThe original histopathologic description of chronic graft-versus-host disease (CGVHD) of the gastrointestinal (GI) tract was from autopsy series. There is little information on the evaluation of living patients with CGVHD and GI symptoms. We reviewed data on 40 consecutive patients with CGVHD and persistent GI symptoms who underwent endoscopic examinations. The diagnosis of CGVHD in these 40 patients was made on the basis of clinical criteria and confirmed by histology of other involved organs in 70%. Patients had progressive (in 19 patients, or 48%), quiescent (in 11, or 27%) or de novo–type (in 10, or 25%) onset of their CGVHD. Four groups were defined based on the following histologic criteria: (1) consistent with acute GI GVHD if there was marked apoptosis with or without cryptitis, (2) suggestive of acute GI GVHD if there was scattered apoptosis with or without cryptitis, (3) suggestive of chronic GI GVHD if there were at least 2 histologic indicators of chronicity such as fibrosis and significant crypt distortion, and (4) no histologic evidence of GVHD. Results of microbiologic, radiologic, and malabsorption studies, if performed, were also retrieved. Median time from diagnosis of CGVHD to GI endoscopy was 4.5 months (0-109 months). The major GI symptoms at the time of endoscopy were diarrhea, abdominal pain/cramping, nausea/vomiting, weight loss, dysphagia, and early satiety. The endoscopic examination was nonspecific for the diagnosis of GI GVHD except for diffuse mucosal sloughing. Based on the histologic criteria in 22 patients with biopsies, 13 cases (59%) were considered to have acute GI GVHD, and 3 cases (14%) were felt to show possible chronic GI GVHD; changes of both acute and chronic GVHD were seen in 6 (27%) cases. GI dysmotility was diagnosed in 7 (18%) patients, including 2 of the patients who had histologic changes suggestive of chronic GVHD. Other causes of the GI symptoms included infection, drug side effect, and malabsorption. In conclusion, GI involvement by acute GVHD appears to be a major cause of persistent GI symptoms in patients with chronic GVHD. An isolated form of chronic GI GVHD confirmed by histology is an uncommon phenomenon in the actual clinical setting. © 2003 American Society for Blood and Marrow TransplantationBiology of Blood and Marrow Transplantation 9:46-51 (2003

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Interpretation: Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.
