Donor Lymphocyte Infusions After Allogeneic Transplantation: A Single-Center Experience.

Allogeneic hematopoietic cell transplantation (AHCT) represents the only curative therapy for many hematological malignancies. The graft versus leukemia effect, driven by donor T cells, plays a major role in its curative potential. This effect is sometimes very evident when patients with acute myeloid leukemia and myelodysplasia relapse after AHCT and are treated with donor lymphocyte infusions (DLIs). We retrospectively reviewed the charts of 64 patients who received DLI between 2012 and 2017 in our center. The mean age of the patients was 59 years (range, 34-79). Fifty percent were male (n = 32). The mean follow-up time after AHCT was 50.17 months (range, 8-174). The indication for DLI were disease progression, mixed chimerism, minimal residual disease, and other etiologies in 43.8%, 40.7%, 14%, and 1.5% of patients, respectively. The most common diagnosis was acute leukemia, followed by multiple myeloma. Of all patients, 59.4% received a transplant from a related donor, 39% received a transplant from an unrelated donor, and 1.6% received a transplant from a haploidentical donor. Reduced-intensity conditioning AHCT was the most frequent regimen used (53%). DLI was given alone in 79.7% of patients. Prophylactic DLI was given at 30 days after transplantation in patients who received human leukocyte antigen (HLA)-matched related human stem cell transplantation (HSCT) or 45 to 60 days post-transplant in patients receiving haploidentical HSCT or HLA-matched unrelated HSCT. Patients were treated without graft versus host disease (GVHD) prophylaxis. The use of DLI after transplantation remains a feasible procedure with rates of response >60%. Moreover, DLIs are well tolerated with a GVHD rate <10% in our series. We can hypothesize that in our experience the efficacy of this strategy does not rely on the induction of GVHD.

The quality of the information provided in post-transplant follow-up is necessary to obtain a coherent and exploitable database. Since the beginning of 2017, three forms (Med-B-allograft) have been available: the first month (Day 0), Day 100 (second report) and an annual follow-up report. Recommendations for follow-up were addressed in the 2014 harmonization workshop, "Harmonization of Data Coding…". However, it is sometimes difficult to determine which data to specify in ProMISe for post-transplantation. The objective of this workshop was to clarify certain situations and/or items.

Rapid Deployment of Aortic Bioprosthesis in Elderly Patients With Small Aortic Annulus.

BACKGROUND: Aortic valve replacement in elderly patients with a small aortic annulus remains challenging. Patient-prosthesis mismatch (PPM) should be prevented without impacting operative mortality. Hemodynamic benefits resulting from rapid-deployment aortic valve replacement with the Edwards Intuity bioprosthesis for this indication were evaluated. METHODS: Elective patients with severe aortic stenosis who required an Edwards Intuity bioprosthesis, size 19 mm and 21 mm, were prospectively included between July 2012 and July 2014. Transthoracic echocardiography was performed preoperatively and at 1-month follow-up. RESULTS: Sixty-six consecutive patients (mean age, 78 ± 6.4 years; 54.5% women) were included. The Intuity 19 mm was inserted in 29 patients, and the Intuity 21 mm was inserted in 37 patients. No deaths or aortic annulus ruptures occurred. Mean aortic cross-clamp time was 42.7 ± 18.2 minutes. At the 1-month follow-up, mean New York Heart Association classification was 1.6 ± 0.5 versus 2.2 ± 0.8 (p < 0.001). The mean gradient decreased from 59 ± 17.6 mm Hg to 13.7 ± 4.4 mm Hg (p < 0.001). Mean indexed effective orifice area was 0.77 ± 0.17 cm(2)/m(2) for the Intuity 19 mm and 1.01 ± 0.32 cm(2)/m(2) for the Intuity 21 mm. Twenty-one patients (32%) had a moderate PPM (indexed effective orifice area < 0.85 cm(2)/m(2)), and 10 patients (15%) had a severe PPM (indexed effective orifice area < 0.65 cm(2)/m(2)). The mean gradient was 15.1 ± 3.5 mm Hg and 16.9 ± 4.9 mm Hg in the moderate PPM group and severe PPM group, respectively (p = 0.3). The left ventricular mass index dramatically decreased from 153.2 ± 32.7 g/m(2) to 118.4 ± 20.2 g/m(2) (p < 0.001), and only 1 patient (1.5%) had a periprosthetic regurgitation greater than 1. CONCLUSIONS: Regarding the low rate of severe PPM and the early regression of left ventricular mass, these preliminary studies indicate the potential benefit of the Intuity bioprosthesis in patients with a small aortic annulus. Midterm results should be evaluated.

In the attempt to harmonize clinical practices between different centers belonging to the Francophone society of bone marrow transplantation and cellular therapy (SFGM-TC), our society set up the sixth annual series of workshops which brought together practitioners from all member centers and took place in September 2015 in Lille. Here, we report our recommendations regarding diagnosis and disease status coding in the ProMISe database used by the SFGM-TC.
