Abstract
Bone marrow transplantation is the only curative treatment for beta-thalassemia major. Data on the co-transplantation of MSCs with HSCs in beta-thalassemia major patients are scarce. We aimed to investigate the outcomes of thalassemia major patients who underwent bone marrow-derived MSC co-transplantation with HSCs compared with those who only received HSCs. This prospective randomized study included patients with class III thalassemia major undergoing HSCT divided randomly into two groups: Thirty-three patients underwent co-transplantation of bone marrow-derived MSCs with HSCs, and 26 patients only received HSCs. Five-year OS, TFS, TRM, graft rejection rate, and GVHD were estimated. The 5-year OS was 66.54% (95% CI, 47.8% to 79.9%) in patients who underwent co-transplantation of MSCs with HSCs vs 76.92% (95% CI, 55.7% to 88.9%) in patients who only received HSCs (P = .54). No significant difference was observed in the 5-year TFS between the two groups (59.1% vs 69.2%; P = .49). The 5-year cumulative incidence of TRM was not statistically significant among patients who underwent co-transplantation of MSCs with HSCs (27.27%) vs those who only received HSCs (19.23%; P = .61). There was no statistically significant difference in graft rejection, acute GvHD, and chronic GvHD between the two groups. Based on our findings, the co-transplantation of MSCs and HSCs to class III thalassemia major patients does not alter their transplantation outcomes including OS, TFS, rejection rate, transplant-related mortality, and GvHD.

Barkhordar, M., Mohammadi, M., Hadjibabaie, M., Ghavamzadeh, A.
International journal of hematology-oncology and stem cell research. 2018;12(2):77-83
Abstract
Background: Allogeneic hematopoietic stem cell transplantation has been used widely to treat various types of malignant and non-malignant disorders. Graft-versus-host disease is one of the main complications of this procedure which is associated with considerable mortality and affects quality of life. Despite careful selection of HLA-matched donors and implementing immunosuppressive therapy, the incidence rate of graft-versus-host disease remains high. Macrolide antibiotics are well-known immunomodulatory agents and have been effective as prophylaxis for graft-versus-host disease in preclinical studies. Materials and Methods: Ninety-six adult patients with acute leukemia were recruited into a double-blind, randomized, placebo-controlled trial. All patients were first-time transplant candidates for a full-matched related or unrelated donor. Patients were allocated to receive azithromycin 500 mg daily (n=48) or placebo (n=48) from day -6 to +12. All patients received high-dose chemotherapy, standard immunosuppressive regimen and supportive care according to institutional protocols. Results: The incidence of acute graft-versus-host disease grade III-IV and chronic graft-versus-host disease garde I-III was not significantly different between the two study arms. Oral mucositis grade 1-3 occurred in significantly lower number of patients in the azithromycin group compared with placebo. Conclusion: Based on the results of this study, protective effect of azithromycin on graft-versus-host disease could not be demonstrated.

Abstract
Oral mucositis (OM) as a complication of high-dose chemotherapy is frequently occurred in hematopoietic stem cell transplantation (HSCT) settings. Erythropoietin (EPO) has anti-inflammatory, antioxidant and wound-healing properties and therefore could have an important role in the prevention of OM. We conducted a double-blind, randomized, placebo-controlled trial to evaluate the EPO mouthwash effect on OM incidence and severity in 80 patients with non-Hodgkin's lymphoma, Hodgkin disease (HD) or multiple myeloma, undergoing autologous hematopoietic stem cell transplantation. Patients received either EPO mouthwash (50IU/ml, 15ml four times a day) (n=40) or placebo (n=40) from the starting day of high-dose chemotherapy until day +14 after transplantation or until the day of discharge from the hospital, whichever occurred first. OM was evaluated daily for 21days after transplantation or until resolution of OM according to World Health Organization oral toxicity scale. The incidence of OM (grades 1-4) in the EPO mouthwash group and control group was significantly different (27.5% vs 77.5%, p<0.001). The mean+/-SD of two other parameters of OM including maximum intensity OM score (0.60+/-1.06 vs 1.67+/-1.27) and average intensity OM score (0.47+/-0.80 vs 1.28+/-0.86) was significantly lower in the intervention group (p<0.001). Moreover, the mean+/-SD duration of OM was also significantly shorter among the EPO mouthwash recipients (1.92+/-3.42days vs 5.42+/-3.86days, P<0.001). Also, the duration of neutropenic fever was significantly shorter in the intervention group (2.12+/-2.42days vs 3.95+/-4.01days, p=0.016). It is concluded that EPO mouthwash can reduce the incidence and duration of OM. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract
Background: Hemorrhagic cystitis (HC) is one of the most challenging complications in hematopoietic stem cell transplantation (HSCT). Estrogen is one of the suggested treatments for controlling this problem. Subjects and Methods: We performed a randomized case-control study to evaluate the efficacy of oral conjugated estrogen on HC management in 56 HSCT patients. Patients were randomly assigned to the drug group (received 6.25 mg conjugated estrogen oral tablets in a daily single dose during hematuria period) or control group. Results: The median time to complete response was 36 and 24 days in the drug and control group, respectively. The median time of down stage was 24 days in the drug group and 12 days in control group. Adjusted for HC grades, the relative risk of complete response for patients in control group was 1.613 times more than that of patients in drug group; nevertheless, not significant (p=0.122). Conclusion: Our study did not show any benefit in use of oral conjugated estrogen in the management of HC.

Abstract
Fanconi anemia is a rare inherited aplastic anemia, which is cured only by hematopoietic stem-cell transplantation (HSCT). One of the most debilitating complications of high-dose chemotherapy regimen before HSCT is oral mucositis (OM), which occurs frequently in this population. Vitamin D has identified immunoregulatory, anti-inflammatory, and antioxidant role. This study was designed to examine the efficacy of vitamin D in the prevention of OM in patients with Fanconi anemia undergoing allogenic HSCT. Twenty-eight patients were enrolled in the study. They received either calcitriol (0.025 mug) or placebo capsule once daily, from the first day of chemotherapy schedule for 14 consecutive days. Incidence of OM was assessed as the primary outcome. Moreover, the association of baseline vitamin D level with OM was evaluated. In this study, calcitriol did not change OM incidence (P = 1) and severity (P = 0.54) significantly; however, a significant association of baseline vitamin D level with OM complete resolution was found (P = 0.03; hazard ratio, 1.01; 95% confidence interval, 1.00-1.01). In conclusion, we did not find considerable benefits of calcitriol in the prevention of OM. However, further studies with bigger sample size and different calcitriol supplementation schedules are needed to confirm these findings.

Abstract
The purpose of this study was to evaluate the effect of oral zinc sulfate in the prevention of chemotherapy-induced mucositis in patients undergoing hematopoietic stem-cell transplantation (HSCT). This study was a double-blind, randomized, placebo-controlled design, with 60 patients undergoing HSCT, divided proportionally in experimental group who received zinc sulfate, and in placebo group. They all had received high-dose chemotherapy conditioning regimen for allogenic transplantation. Oral mucositis assessed was based on World Health Organization (WHO) oral mucositis scale. There were no significant differences in the development of mucositis between the two groups. Severity of mucositis was not significantly different between the two groups either. The same result was obtained regarding the duration of mucositis. Zinc sulfate did not show any significant adverse effects in experimental group. In conclusion, Zinc sulfate did not have any clinical benefits in prevention or reduction of severity, and duration of high-dose chemotherapy-induced mucositis in patients undergoing HSCT.
