Circadian Rhythmicity as a Predictor of Quality of Life in Allogeneic Hematopoietic Cell Transplant Patients.

ABSTRACT: CONTEXT:Quality of life (QoL) is increasingly recognized as an important outcome of cancer treatment. Previous studies have examined clinical predictors of QoL, but with the increasing prevalence of wearable sensors that monitor sleep and activity patterns, further investigation into whether these behaviors are predictive of post-treatment QoL is now feasible. Among patients receiving aggressive cancer treatment such as hematopoietic cell transplantation (HCT), analysis of circadian rhythms (24-hour patterns of sleep and activity) via wearable sensors is limited. OBJECTIVE:To evaluate the relationship between overall QoL and circadian rhythms in patients receiving allogeneic HCT. METHODS:Patients wore an ActiGraph GT3X (Pensacola, FL) activity monitor for at least 72 hours before the initiation of conditioning chemotherapy and transplantation and completed a QoL (Functional Assessment of Cancer Therapy-General [FACT-G]) assessment. QoL assessments were also completed 1, 3, and 6 months after HCT. RESULTS:Patients (n = 45, M age = 55) were mostly male (66%) with a total FACT-G score of 80.96 (SD = 16.05) before HCT. Mixed models revealed robust cross-sectional associations between overall QoL and multiple circadian rhythmicity parameters, including durations of high physical activity, overall circadian rhythmicity, and earlier starts of daily activity (P's < .01). Recovery of QoL after transplant was predicted by longer pre-transplant durations of high physical activity (P = .04) and earlier evening retirement (P = .04). CONCLUSION:Our findings suggest that wearable sensor information is a promising method of predicting recovery of QoL after HCT. Additional studies are needed to confirm these findings in a larger sample.

Project description:We sought to describe the clinical experience of voriconazole as primary antifungal prophylaxis (AFP) in allogeneic hematopoietic cell transplant recipients (allo-HCTr). This was a single-center retrospective study of adult allo-HCTr (1 January 2014 to 31 December 2016) who received ≥two doses of voriconazole-AFP. Voriconazole-AFP was started on day +7 post-HCT and continued at least through day +60 post-HCT, or longer as clinically indicated. We reviewed the rate, reasons, and risk factors of voriconazole-AFP discontinuation until day-100 post-HCT. A total of 327 patients were included. Voriconazole-AFP was continued for a median of 69 days (mean: 57.9; range 1, 100): for a median of 90 days (mean :84; range 2, 100) in 180/327 (55%) in the standard-of-care (SOC) group and 20 days (mean :25.6 ; range 1, 89; P-value < .001) in 147/327 (45%) patients in the early-discontinuation-group. Early-voriconazole-AFP discontinuation was due to adverse events, drug interactions, insurance coverage, and other reasons in 101/147 (68.7%), 27 (18.4%), 13 (8.8%), and 6 (4.1%) patients, respectively. Early-voriconazole-AFP discontinuation occurred in 73/327 (22.3%) patients due to hepatotoxicity. Important predictors for early-voriconazole-AFP discontinuation included: graft-versus-host disease grade ≥2 (odds ratio [OR]: 1.9, P-value: .02), alanine-aminotransferase ≥75 IU/ml on voriconazole-administration day-14 (OR: 5.6, P-value: .02) and total bilirubin ≥1.3 mg/dl on voriconazole-administration day-7 (OR: 3.0, P-value: .03). There were 13 proven/probable invasive fungal infections by day-180 post-HCT (8/147, 5.4%, and 5/180, 2.8% in the early-discontinuation and SOC-groups, respectively; log-rank:0.13). By day-180 post HCT, 23/147 (15.6%) and 14/180 (7.8%) patients in the early-discontinuation and SOC-groups had died, respectively (log-rank:0.03). Voriconazole-AFP was discontinued in up to 45% of allo-HCTr. Hepatotoxicity during the first 2 weeks post-HCT is a significant predictor of early-voriconazole-AFP discontinuation.

Project description:Importance:Studies demonstrating improved survival after allogeneic hematopoietic cell transplant generally exclude infants. Objective:To analyze overall survival trends and other outcomes among infants who undergo allogeneic hematopoietic cell transplant. Design, Setting, and Participants:In this cohort study, we used time-trend analysis to evaluate 3 periods: 2000 through 2004, 2005 through 2009, and 2010 through 2014. The study was conducted in a multicenter setting through the Center for International Blood and Marrow Transplant Research, which is made up of a voluntary working group of more than 450 transplant centers worldwide. Two groups of infants aged 1 year or younger in 2 cohorts were included: those with malignant conditions, such as leukemia, and those with nonmalignant disorders, including immunodeficiencies. Data analysis was conducted from July 2017 to December 2018. Exposures:Allogeneic hematopoietic cell transplant. Main Outcomes and Measures:Survival trends, disease relapse, and toxicity. Results:A total of 2498 infants with a median age of 7 months (range, <1-12 months) were included. In the nonmalignant cohort (n = 472), survival rates improved from the first to the second period (hazard ratio, 0.77 [95% CI, 0.63-0.93]; P = .007) but did not change after 2004. Compared with infants with nonmalignant diseases (n = 2026; 3-year overall survival: 2000-2004, 375/577 [65.0%]; 2005-2009, 503/699 [72.0%]; and 2010-2014, 555/750 [74.0%]), those with malignant conditions had poorer survival rates, without improvement over time (3-year overall survival: 2000-2004, 109/199 [54.8%]; 2005-2009, 104/161 [64.6%]; and 2010-2014, 66/112 [58.9%]). From 2000 through 2014, relapse rates increased in infants with malignant conditions (3-year relapse rate: 2000-2004, 19% [95% CI, 14%-25%]; 2005-2009, 23% [95% CI, 17%-30%]; 2010-2014, 36% [95% CI, 27%-46%]; P = .01). Sinusoidal obstruction syndrome was frequent, occurring with a cumulative incidence of 13% (95% CI, 11%-16%) of infants with nonmalignant diseases and 32% (95% CI, 22%-42%) of those with malignant diseases. Generally, recipients of human leukocyte antigen-identical sibling bone marrow grafts had the best outcomes. Conclusions and Relevance:Survival rates have not improved for infants with malignant diseases over the 15-year study period. Infants with nonmalignant diseases had improved survival rates in the earlier but not the later study period. Higher relapses for the malignant cohort and toxicities for all infants remain significant challenges. Strategies to reduce relapse and toxicity and optimize donor and graft selection may improve outcomes in the future.

Project description:BackgroundRelationships between microbiota composition and clinical outcomes after allogeneic hematopoietic-cell transplantation have been described in single-center studies. Geographic variations in the composition of human microbial communities and differences in clinical practices across institutions raise the question of whether these associations are generalizable.MethodsThe microbiota composition of fecal samples obtained from patients who were undergoing allogeneic hematopoietic-cell transplantation at four centers was profiled by means of 16S ribosomal RNA gene sequencing. In an observational study, we examined associations between microbiota diversity and mortality using Cox proportional-hazards analysis. For stratification of the cohorts into higher- and lower-diversity groups, the median diversity value that was observed at the study center in New York was used. In the analysis of independent cohorts, the New York center was cohort 1, and three centers in Germany, Japan, and North Carolina composed cohort 2. Cohort 1 and subgroups within it were analyzed for additional outcomes, including transplantation-related death.ResultsWe profiled 8767 fecal samples obtained from 1362 patients undergoing allogeneic hematopoietic-cell transplantation at the four centers. We observed patterns of microbiota disruption characterized by loss of diversity and domination by single taxa. Higher diversity of intestinal microbiota was associated with a lower risk of death in independent cohorts (cohort 1: 104 deaths among 354 patients in the higher-diversity group vs. 136 deaths among 350 patients in the lower-diversity group; adjusted hazard ratio, 0.71; 95% confidence interval [CI], 0.55 to 0.92; cohort 2: 18 deaths among 87 patients in the higher-diversity group vs. 35 deaths among 92 patients in the lower-diversity group; adjusted hazard ratio, 0.49; 95% CI, 0.27 to 0.90). Subgroup analyses identified an association between lower intestinal diversity and higher risks of transplantation-related death and death attributable to graft-versus-host disease. Baseline samples obtained before transplantation already showed evidence of microbiome disruption, and lower diversity before transplantation was associated with poor survival.ConclusionsPatterns of microbiota disruption during allogeneic hematopoietic-cell transplantation were similar across transplantation centers and geographic locations; patterns were characterized by loss of diversity and domination by single taxa. Higher diversity of intestinal microbiota at the time of neutrophil engraftment was associated with lower mortality. (Funded by the National Cancer Institute and others.).
