Risk Of Mortality

Abstract Abstract 1954 Introduction: Vitamin D (VD) deficiency can cause osteomalacia, aching bone pain, muscle weakness, fatigue, increase risk of fracture and precipitate or exacerbate osteopenia/osteoporosis. Allogeneic hematopoietic stem cell transplant (HCT) patients are susceptible to low VD level secondary to poor oral intake, decreased exposure to sunlight and treatment related malabsorption. VD level has been correlated to cancer incidence and VD metabolites have been used in the treatment of myeloid leukemia. VD shows promising immunomodulatory properties and correction of low VD level may mitigate manifestations of graft versus host disease (GVHD). Reports have suggested that low VD level appears to increase the incidence of GVHD. We hypothesize that there is a relationship between low VD level and morbidity (specifically incidence of acute GVHD), mortality and relapse incidence after HCT. We therefore studied VD levels pre- and post-HCT to determine if VD level impacts these outcomes. Patients and Methods: 241 patients underwent myeloblative or non-myeloablative HCT between January 1, 2009 and January 31, 2011 at our institution. Baseline demographic data, disease characteristics, transplant variables and outcomes data were obtained from the transplant database. These data were supplemented by retrospective chart review for pre- and post-transplant VD level. Categories for VD level included normal (>30 ng/ml) or abnormal (<30 ng/ml). Results: 131 (54%) of patients who underwent myeloblative or non-myeloablative HCT had their VD level evaluated either pre-transplant, post-transplant or both. Pre-HCT 57 (56%) patients, 100 days post-HCT 55 (59%) patients and 365 days post-HCT 12 (32%) patients had a low VD level. 51 (38%) of patients had a reduced intensity HCT and 80 patients (62%) had an ablative conditioning regimen. 11 (8.4%) patients had acute GVHD. Comparison of VD level among those with acute GVHD did show a higher incidence of acute GVHD between those with a low or normal VD level (HR=3.14, 95% CI: 0.35–28.33) however this association was not statistically significant (p=0.3079). Survival analysis in those with a low VD level pre-HCT showed there was not a higher risk of mortality (HR=1.14, 95% CI: 0.18–7.38) after adjusting for post- VD level, and this association was not statistically significant (p=0.8921). Survival analysis in those with a low VD level post-HCT did show a higher risk of mortality (HR=2.59, 95% CI: 0.26–25) after adjusting for pre-HCT VD level, however, this association was not statistically significant (p=0.4155). The relationship between VD level and relapse at 1 year post-HCT was not able to be examined because the VD level for patients who relapsed was not available. Conclusions: Half of patients undergoing HCT had VD testing pre- or post- HCT. Just over half of the patients tested had a low VD level pre- and 100 days post-HCT. It is notable that 365 days post HCT the number of patients with low VD level had decreased. This could be attributable to less time in the hospital thus increasing sun exposure, increasing performance status allowing better ingestion and absorption of VD in the gastrointestinal tract or proper supplementation of a low level noted previously. There was no significant difference in incidence of acute GVHD by VD level though there was a trend for increased risk. Pre- and post-HCT VD level did not significantly impact mortality but there was a trend toward higher risk in those with a low VD level post-HCT. This is the first study, to our knowledge, to evaluate the impact of VD level on mortality post-HCT. Our study confirms that many patients have a low VD level pre-and post-HCT. These findings, especially the trend towards a higher mortality risk and higher incidence of acute GVHD in those who have a low VD level post-HCT, warrant further prospective investigation. VD supplementation may be a low cost, easy to implement addition to routine post HCT care that might reduce HCT associated mortality. Disclosures: Reeder: Celgene: Research Funding.

Introduction Allogeneic hematopoietic stem cell transplant (HCT) patients are at risk for having a low Vitamin D (VD) level. VD level has been correlated with cancer incidence, pulmonary disease and infection. VD also has immunomodulatory properties and reports suggest that a low VD level increases the incidence of chronic GVHD and may impact mortality in HCT. HCT morbidity and mortality is attributed to infection, organ system toxicity, GVHD and recurrent disease. Identifying a correctable factor that would reduce the occurrence or severity of these complications would be beneficial. It is possible that VD may have significant effect on outcome after HCT due to its described properties. Normal VD level may infer better outcome for HCT patients by improving response in or preventing infection, protecting organ function, decreasing risk of relapse and/or decrease incidence or severity of GVHD. We hypothesize that there is a relationship between VD level and morbidity and mortality after HCT. We therefore studied VD levels pre- and post-HCT to determine if there was an impact of VD level on these outcomes. Patients and Methods Two hundred and fifty patients underwent myeloblative or non-myeloablative HCT between 3/12/2009 and 10/29/2012 at our institution. Baseline demographic data, disease characteristics, transplant variables and outcomes data were obtained from the transplant database. These data were supplemented by retrospective chart review for VD levels prior to transplant, at day 100 and 1 year post-HCT. Data were collected through day 100 for occurrence of infection and admissions to the ICU. Categories for VD level included normal (≥30 ng/ml) or abnormal (<30 ng/ml). Patient characteristics were compared using the Chi-square test or Wilcoxon rank sum test. The logrank test was used to compare the survival curves between groups, and the Cox proportional hazard model was used to measure the association between outcomes (mortality, relapse, acute or chronic GVHD) and VD level. Results Of the 250 patients undergoing HCT VD level was performed on 180 (72%) patients pre-HCT, 149 (60%) patients at day 100 post-HCT and 81 (32%) patients at 1 year post-HCT. The rate of acute or chronic GVHD was not significantly associated with VD level pre or post-HCT. Overall infection risk was not significant pre or post-HCT but when sorted by type of infection bacterial infection (p=0.01), radiologic evidence of pulmonary nodules/consolidation (p=0.03), and ICU admissions (p=0.0313) within the first 100 days post-transplant were significantly increased in patients who had a low VD level at day 100 post -HCT. Pre-HCT and 1 year post-HCT VD level did not impact mortality or relapse but there was a significant increase in one year mortality (p=0.02, HR = 5.99) and relapse (p = 0.03, HR=9.47) in patients who had a low VD level at day 100 post-HCT. Discussion This study shows that VD may play a significant role in bacterial infection, pulmonary infection, ICU admission, mortality and relapse after HCT. Those patients with a low VD level at day 100 post-HCT had significantly worse outcomes for relapse and mortality. Those patients with a low VD level at day 100 post-HCT had a higher incidence of lung infection, bacterial infection and admission to the ICU. In contrast to previous studies, we found no correlation between VD level and incidence of acute or chronic GVHD. This study is one of the largest reported and the first to our knowledge that reports decreased risk of certain types of infection (bacterial and lung), mortality and relapse in those with an adequate VD level receiving HCT. It is possible that supplementation of VD to keep levels ≥30 would reduce these complications of HCT. Future prospective study of VD is warranted. Finding a low cost and easy to administer therapy (such as VD replacement) that would reduce morbidity, mortality and relapse in the HCT population is needed.
