We studied 172 patients for development of ocular graft-versus-host disease (GVHD) after allogeneic stem cell transplantation (allo-SCT) from 2002 to 2009. Ocular GVHD was diagnosed in 60 patients (38%), with 27 (16%) being diagnosed at days 100 and 33 (23%) beyond day 100 for a 2-year cumulative incidence of 35% (95% confidence interval (CI), 28 --43). The positive and negative predictive values of a Schirmer I test score (using p5 mm as a cutoff) in predicting ocular GVHD (day 100) were 41 and 82%, respectively. In patients with ocular GVHD beyond day 100, extraocular manifestations of GVHD preceded the development of ocular GVHD in most patients (27 of 33, 81%). Prior acute skin GVHD (odds ratio 2.57, 95% CI 1.17 --5.64, P ¼ 0.019) and male recipients of female donors (odds ratio 2.57, 95% CI 1.09 --6.06, P ¼ 0.03) were independent risk factors for ocular GVHD. We recommend comprehensive ocular evaluation rather than a screening Schirmer's test to establish the diagnosis of ocular GVHD. Early diagnosis and preventive strategies in high-risk populations need to be studied in clinical trials to prevent devastating impact on quality of life in patients with prolonged ocular GVHD.
Hematopoietic stem cell transplantation (HCT) survivors are less likely than matched healthy controls to mount a strong immune response to trivalent inactivated influenza vaccine (TIV). High-dose (HD) or standard-dose (SD) TIV were given to adult HCT subjects 18 years or older at least 6 months after transplantation. Subjects were randomized 2:1 to receive either the HD (60 μg hemagglutinin [HA]/strain/dose) or the SD (15 μg HA/strain/dose) TIV. Injection-site and systemic reactions were documented after each vaccination and immune responses were measured before and after each vaccination. A total of 44 subjects were enrolled (25 in year 1 and 19 in year 2), with 15 in the SD group and 29 in the HD group. The median time to vaccination after transplantation was 7.9 months (range, 6 to 106 months), the median age was 50 years (range, 19.6 to 73 years), and 61% were male. No differences in demographic or lab data were noted between groups; however, the HD group had higher median baseline total IgG level (676 versus 469 mg/dL, P = .025). No differences in individual injection-site or systemic reactions were noted between groups; however, more events of any injection-site symptom combined were reported in the HD group. No serious adverse events were attributed to vaccination. After vaccination, the HD group had a higher percentage of individuals with titers ≥1:40 and a higher geometric mean titer (GMT) against the H3N2 strain compared with that of the SD group. HD and SD TIV were found to be safe and well tolerated in adult HCT recipients. However, the HD group had higher frequency of injection-site reactions but the majority of the reactions were mild and resolved. The HD group had a higher percentage of individuals with post-vaccination titer ≥ 1:40 and GMT for H3N2 antigen, indicating better immunogenicity. These data support the need for a phase II immunogenicity trial in HCT recipients.
, and the prognostic impact of FMS-like tyrosine kinase 3/internal tandem duplication (FLT3/ITD) mutation was evaluated in the context of other clinical prognostic factors. Patients with FLT3/ITD þ AML had significantly inferior DFS (2-year DFS: 19% vs 64%, P ¼ 0.0027), increased risk of relapse (1-year: 59% vs 19%, P ¼ 0.01), and a trend towards decreased OS (P ¼ 0.08) compared with patients without FLT3/ITD. Multivariate analysis confirmed FLT3/ITD þ independently predicted a shorter DFS (HR, 3.0; 95% CI), 1.4-6.5; P ¼ 0.01) and increased risk of relapse (HR, 4.9; 95% CI, 2.0-12.3, P ¼ 0.01). Time to relapse in patients with FLT3/ITD þ was short with 100-day cumulative risk of 45% (95% CI, 33-57). Our data suggest that the poor prognostic implication of FLT3/ITD positivity remains even after early allo-SCT in patients with FLT3/ITD þ AML, and patients remain at high risk of early relapse. FLT3/ITD positivity also outweighs other conventional prognostic markers in predicting relapse.
Extracorporeal photopheresis (ECP) has been shown to be a promising treatment for chronic graft-versus-host disease; however, only a few case reports are available that examine the effectiveness of ECP for bronchiolitis obliterans (BO) after allo-SCT. Because of the poor response to traditional therapies, ECP has been explored as a possible therapeutic option for severe BO after allo-SCT. Nine patients received ECP between July 2008 and August 2009 after a median follow-up of 23 months (range 9-93 months) post transplant. The primary indication for ECP was the development of BO in patients who had failed prior multidrug regimens. The median number of drugs used for BO management before ECP was 5 (range 2-7); this included immunosuppressive therapy. Six of nine (67%) patients responded to ECP after a median of 25 days (range 20-958 days). No ECP-related complications occurred. ECP seemed to stabilize rapidly declining pulmonary function tests in about two-thirds of patients with severe and heavily pretreated BO that developed after allo-SCT. This finding supports the need for a larger prospective study to confirm the impact of ECP on BO, and to consider earlier intervention with ECP to improve the outcome of BO after allo-SCT.
The optimal healthcare model for follow-up of allogeneic hematopoietic stem cell transplantation (HSCT) recipients after day 100 is not clear. We previously demonstrated that longitudinal follow-up at the transplant center using a multidisciplinary approach is associated with superior survival. Recent data suggest that increased distance from the transplant center is associated with inferior survival. A dedicated long-term transplant clinic (LTTC) was established in 2006 at our center. We hypothesized that geographic distance would not be associated with inferior outcome if patients are followed in the LTTC. We studied 299 consecutive patients who underwent HSCT and established care in an LTTC. The median distance from the transplant center was 118 miles (range, 1 to 1591). The 75th percentile (170 miles) was used as the cut-off to analyze the impact of distance from the center on outcome (219 patients ≤ 75th percentile; 80 patients >75th percentile). The 2 groups were balanced for pretransplant characteristics. In multivariate analyses adjusted for donor type, Center for International Blood and Marrow Transplant Research risk, and transplant regimen intensity, distance from transplant center did not impact outcome. Our study suggests that geographic distance from the transplant center is not associated with inferior outcome when follow-up care is delivered via a dedicated LTTC incorporating well-coordinated multidisciplinary care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
