The widespread use of complementary and alternative medicine (CAM) in cancer survivors is well known despite a paucity of scientific evidence to support its use. The number of survivors of hematopoietic stem cell transplant (HCT) is growing rapidly and HCT clinicians are aware that many of their patients use CAM therapies consistently. However, due to a paucity of data regarding the benefits and harms of CAM therapies in these survivors, clinicians are reluctant to provide specific recommendations for or against particular CAM therapies. A systematic literature review was conducted with a search using PubMed, the Cochrane Database of Systematic Reviews, and Ovid online for each CAM therapy as defined by the National Center of Complementary and Alternative Medicine. The search generated 462 references, of which 26 articles were deemed to be relevant for the review. Due to extensive heterogeneity in data and limited randomized trials, a meta‐analysis could not be performed but a comprehensive systematic review was conducted with specified outcomes for each CAM therapy. In randomized controlled trials, certain mind and body interventions such as relaxation were observed to be effective in alleviating psychological symptoms in patients undergoing HCT, whereas the majority of the other CAM treatments were found to have mixed results. CAM use is an understudied area in HCT survivorship and clinicians should convey the benefits and uncertainties concerning the role of CAM therapies to their patients.

AbstractProgressive multifocal leukoencephalopathy (PML), a demyelinating disorder caused by brain infection with JC virus, is a neurological complication of immunocompromised states and immunosuppressive therapies. While most commonly seen in the HIV/AIDS population, patients with hematologic malignancies are also at risk following treatment protocols including monoclonal antibodies such as rituximab and after hematopoietic stem cell transplantation. Here, we present the case of PML following allogeneic HCT that highlights potential diagnostic difficulties. We also review the literature regarding PML following HCT and described therapies employed to attempt to treat this disorder.

Abstract Previous studies have reported mortality rates of about 80% in hematopoietic stem cell transplant recipients with diffuse alveolar hemorrhage. This retrospective study describes the clinical course of 48 such patients: mean age 47.7 years, 52% autologous transplant and 67% peripheral stem cell source. The hemorrhage occurred within one month of transplant in 28 patients. Symptoms included dyspnea in 92%, fever in 67%, cough in 56%, and hemoptysis in 15%. Intensive care unit admission was required in 85% and mechanical ventilation in 77%. Most of the patients were treated with intravenous methylprednisolone 1 g daily for 3 days and then tapered off after a median of 22 days. The hospital mortality was 48%. The cause of death was respiratory failure in 15 of the 23 deaths. Mortality was 28% in autologous compared with 70% in allogeneic transplant recipients (p = 0.0040). The mortality rate of patients whose hemorrhage occurred within the first 30 days of transplant was 32% compared with 70% of those with late hemorrhage (p = 0.0096). This study shows that survival rate of hematopoietic stem cell transplant recipients with diffuse alveolar hemorrhage is better than previously reported, and that early onset and autologous transplant are favorable prognostic indicators.
