Despite numerous reports of significant distress and burden for hematopoietic stem cell transplantation (HSCT) patients and caregivers (CGs), HSCT-specific coping interventions remain rare. The few in use lack specificity and are often not easily accessible or cost-effective. Whereas the development of new interventions is resource-intensive, theory-informed adaptation of existing evidence-based interventions is promising. To date, no HSCT-specific intervention has relied on a formal adaptation approach. Using the Center for Disease Control and Prevention’s Map of Adaptation, this two-phase qualitative descriptive study seeks to understand the perceptions of HSCT patients, CGs, individually, and in dyads, and clinicians about Coping Together (CT) for the preliminary adaptation (Phase 1), and then explores perceptions of the modified intervention in additional mixed sample (Phase 2). Six to ten participants including outpatients, CGs and dyads and five to seven HSCT clinician participants will be recruited for Phase 1. For Phase 2, 14 to 16 participants including outpatients, CGs and dyads will be recruited. Individual and dyadic semi-structured interviews will take place between 100 and 130 days post-HSCT. Verbatim transcripts will be analyzed using content analysis. It is paramount to have HSCT-specific supportive interventions that address patients’ and CGs’ multidimensional and complex needs. The timely involvement of key stakeholders throughout the adaptation process is likely to optimize the relevance and uptake of such tailored intervention.

Hematopoietic stem cell transplant (HSCT) recipients are at significant risk for BK virus (BKV) reactivation, hemorrhagic cystitis (HC), and renal dysfunction. We prospectively monitored 98 patients who had received HSCT by serial BKV PCR in the urine through day (D) +100 to analyze the relationship between BK viruria and HC, serum creatinine (Cr), and creatinine clearance (CrCl) through D +180 or death. Patients, median age 52 years (range, 20 to 73), received T cell–depleted (50%) or cord blood allografts (21%). Median pre-HSCT BKV IgG titers were 1:10,240. Incremental increase in BKV IgG titers correlated with developing BK viruria ≥ 107 copies/mL. By D +100, 53 (54%) patients had BK viruria. BKV load in the urine increased at engraftment and persisted throughout D +100. HC developed in 10 patients (10%); 7 of 10 with BK viruria. In competing risk analyses, BK viruria ≥ 107 copies/mL, older age, cytomegalovirus reactivation, and foscarnet use were risk factors for HC. Cr and CrCl at 2, 3, and 6 months after HSCT were similar between patients with and without BK viruria.

Bloodstream infection by highly antibiotic-resistant bacteria, such as vancomycin-resistant Enterococcus (VRE), is a growing clinical problem that increasingly defies medical intervention. Identifying patients at high risk for bacterial sepsis remains an important clinical challenge. Recent studies have shown that antibiotics can alter microbial diversity in the intestine. Here, we characterized these effects using 16s rDNA pyrosequencing and demonstrated that antibiotic treatment of mice enabled exogenously administered VRE to efficiently and nearly completely displace the normal microbiota of the small and large intestine. In the clinical setting, we found that intestinal domination by VRE preceded bloodstream infection in patients undergoing allogeneic hematopoietic stem cell transplantation. Our results demonstrate that antibiotics perturb the normal commensal microbiota and set the stage for intestinal domination by bacteria associated with hospital-acquired infections. Thus, high-throughput DNA sequencing of the intestinal microbiota could identify patients at high risk of developing bacterial sepsis.
