Abstract Background Heparin-induced thrombocytopenia (HIT) is an immune-mediated drug reaction in which heparin-dependant IgG antibodies (HIT-IgG) to heparin-platelet factor 4 complexes form with the potential for platelet activation with resultant thrombocytopenia (HIT) and thrombosis (HITT). The frequency of HIT-IgG formation and clinically apparent HIT or HITT varies considerably, according to the patient population (surgical versus medical) and type of heparin (unfractionated [UFH] vs low molecular weight [LMWH]). One large prospective study showed a frequency of HIT-IgG formation of 7.5% with clinical HITT in 34.5% of these orthopedic patients receiving prophylactic LMWH and corresponding figures in cardiac surgery patients receiving UFH were 50% and 2%, respectively [Warkentin et al. Blood2000;96: 1703]. Due to daily exposure to heparin flushes (UFH) and prophylactic LMWH (to prevent venoocclusive disease) hematopoietic stem cell transplant (HSCT) recipients may be at risk for HIT/HITT. However, due to anticipated post-transplant thrombocytopenia, clinical cases of HIT/HITT may be overlooked. We retrospectively determined the incidence of HIT-IgG formation and its clinical significance in this population. Methods: HIT-IgG was measured retrospectively using a commercially available ELISA kit in samples collected from patients prior to conditioning therapy and on day 14 post-HSCT. Medical records were reviewed to in order to determine the clinical significance (development of clinical HIT/HITT) in those with detectable HIT-IgG. Patients Samples from a total of 103 HSCT recipients with hematologic malignancy (including 25 myeloma, 17 lymphoma, 16 AML, 14 amyloid, 10 MDS, 10 ALL, 8 CML and 3 CLL) were tested, of which 52 and 49 underwent allogeneic and autologous HSCT, respectively. All patients were exposed to UFH flushes during line care. In addition, all allogeneic recipients received prophylactic subcutaneous dalteparin 5000U daily beginning with conditioning until engraftment. Conditioning regimens included high dose melphalan (n=34), cyclophosphamide/TBI (n=30), carmustine, etoposide, cytarabine, melphalan (n=15), busulfan/cyclophosphamide (n=9), fludarabine/melphalan (n=10) and fludarabine/TBI (n=4). The median age was 51.5 years (20–72) and 68 were male. Results: The median platelet count prior to initiation of conditioning therapy and at day 14 was 157 × 109/L (range: 10–672) and 40 × 109/L (range: 9–289), respectively. Prior to conditioning, two of 103 (1.9%) patients had a positive HIT-IgG assay, that became negative in one and equivocal in the other by day 14 post-HSCT, and one patient had an equivocal HIT assay that became negative by day 14. All 3 were autologous recipients. None of the previously negative patients had a positive HIT-IgG assay at day 14, although 3 patients (2 autologous and one allogeneic) had an equivocal result of uncertain significance. No patients developed clinical or symptomatic thrombosis (HITT). Conclusion: In spite of frequent exposure to heparin, the frequency of seroconversion is low, and in those patients with preexisting HIT-IgG, no patient developed symptomatic thrombosis, including the 2 patients with positive HIT IgG assays prior to conditioning. The low frequency of HIT-IgG formation may reflect the profound immunosuppression of the conditioning regimens employed. Nevertheless, in this population, a high index of clinical suspicion must be maintained.

Abstract Abstract 2400 Background: Approximately 10% of patients with multiple myeloma (MM) have clinically overt primary systemic light-chain (AL) amyloidosis, and about 30% have concurrent occult AL amyloidosis. The impact of concurrent AL amyloidosis on the prognosis of myeloma is not well known. High-dose melphalan followed by autologous hematopoietic stem cell transplant (auto HCT) has shown significant activity in both MM and AL amyloidosis. Methods: We performed a retrospective analysis of patients who had concurrent MM and AL amyloidosis and underwent auto HSCT with high dose Melphalan at MDACC between 01/1998 to 05/2010. We identified 41 patients with concurrent MM and AL amyloidosis. Patient characteristics are summarized in Table 1. Twenty -six patients had occult AL amyloid, while 15 had clinically overt disease. Results: Median age at auto HSCT was 56 years (39-77), 58.5% being male with median follow up of 58.7 months from the time of diagnosis and 42.5 months from auto HCT. The median time from diagnosis to auto HCT was 8.9 mos (2.7-102.4 mos). 39% had Salmon Durie Stage III disease and 36.6% had more than one involved site at the time of transplant.Cytogenetic abnormalities were detected in 24.4% of patients. Post transplant hematologic responses were as follows: ≥CR=10 (24%), ≥VGPR=16 (39%), >PR=33 (80.5%), ≥stable disease= 40 (97.6%). Among the patients with overt organ involvement, one had early death. Of the 15 evaluable patients, organ responses were scored using the published consensus guidelines for amyloidosis and were as follows: PR=5 (33.3%), ≥SD=7 (46.7%). No correlation was seen between organ response and hematologic response. The 100-day treatment related mortality (TRM) was 0 and 1-year TRM of 2.4% which is comparable to patients transplanted for MM alone at our center. The median progression-free (PFS) and overall survival (OS) from auto HCT were 33.8 and 58.3 months, respectively.The median PFS and OS from diagnosis were 49.8 and 96 mos, respectively. In multivariate analysis, creatinine ≥ 2mg/dl was associated with a shorter PFS (p=0.043) and hemoglobin <10g/dl showed a trend towards a shorter PFS (p=0.093). None of these variables (Hb <10g/dl, Age>60yrs, Creatinine≥2mg/dl, B2M >3.5mg/l, BM plasma cells>30%) emerged as significant predictors of OS. There was no significant difference in outcome between patients with occult or symptomatic AL amyloidosis for OS (p=0.24) or PFS (P=0.9) Conclusion: In this analysis the outcome of patients with concurrent MM and AL amyloidosis was comparable to patients with MM alone. We believe these patients are acceptable candidates for auto HCT.

Background Up to 70% of patients receiving hematopoietic stem cell transplant develop oral mucositis as a side effect of high-dose melphalan conditioning chemotherapy. Oral cryotherapy has been documented to be potentially effective in reducing oral mucositis. The aim of this study was to examine the effectiveness of the cryotherapy protocol implemented within the hematopoietic stem cell transplant program. Methods A retrospective chart review was conducted of adult multiple myeloma patients who received high-dose melphalan conditioning therapy for autologous hematopoietic stem cell transplant. Primary endpoints were incidence and severity of oral mucositis. Secondary endpoints included duration of oral mucositis, duration of hospital stay, parenteral narcotics use and total parenteral nutrition use. Results One hundred and forty patients were included in the study, 70 patients in both no cryotherapy and cryotherapy groups. Both oral mucositis incidence and severity were found to be significantly lower in the cryotherapy group. Fifty (71.4%) experienced mucositis post cryotherapy compared to 67 (95.7%) in the no cryotherapy group (p < 0.001). The median oral mucositis severity, assessed using the WHO oral toxicity scale from grade 0–4, experienced in the no group was 2.5 vs. 2 in the cryotherapy group (p = 0.03). Oral mucositis duration and use of parenteral narcotics were also significantly reduced. Duration of hospital stay and use of parenteral nutrition were similar between the two groups. Conclusion The cryotherapy protocol resulted in a significantly lower incidence and severity of oral mucositis. These results provide evidence for the continued use of oral cryotherapy, an inexpensive and generally well-tolerated practice.
