Incidence And Mortality

Abstract Background Antifungal prophylaxis may result in breakthrough infections in hematology patients with severe agranulocytosis, with few studies assessing risk factors and clinical outcomes of breakthrough candidemia. We described the distribution of Candida species, assessed risk factors for mortality in such patients, and determined differences in the incidence and mortality of breakthrough candidemia between patients who did or did not receive an allogeneic hematopoietic stem cell transplant. Methods We collected clinical and microbiological data of patients with hematologic malignancies and breakthrough candidemia from a single center. Seven-day and 30-day follow-up outcomes were recorded; the incidence and mortality of breakthrough candidemia between patients who did or did not undergo an allogeneic transplant were compared. Kaplan-Meier survival estimates were used to generate survival curves, and predictors were identified using Cox regression analyses. Results Of 71 enrolled patients, 17 received allogeneic transplants. Incidences of breakthrough candidemia were 17 of 2924 (0.58%) and 54 of 12 015 (0.45%) in the transplant and nontransplant groups, respectively (P = .35). The most common isolate was Candida tropicalis, and antifungal agent combinations were the most common first-line treatment. Cumulative mortality rates of patients were 21.1% and 31.0% at days 7 and 30, respectively, and they significantly differed between both groups. Septic shock, central venous catheter removal, and granulocyte recovery were significantly associated with 7-day mortality; the latter 2 remained independent predictors of 30-day mortality. Conclusions Breakthrough candidemia-related mortality was higher in the allogeneic transplant group, although the incidence was not significantly different between the groups. Prompt and adequate antifungal treatment with catheter removal may reduce mortality.

Increased Risk

Abstract Thrombotic microangiopathy (TMA) is a multifactorial complication of related and unrelated allogeneic hematopoietic stem cell transplant (allo-HSCT). The true incidence of TMA is difficult to estimate due to lack of agreement on a single definition. Diagnosis is often complicated by multiple potential etiologies for the clinical findings. Sirolimus (SIR), an inhibitor of mammalian target of Rapamycin (mTOR), is a novel immunosuppressive agent that works synergistically with calcineurin inhibitors (CNI) to prevent graft-versus-host disease (GVHD) in allo-HSCT. Recently, the addition of SIR to CNIs was reported to result in a higher than expected incidence (10.8%) of TMA (Cutler et al. BBMT2005; 11:551–7). We evaluated the incidence and risk factors for TMA in a cohort of patients undergoing matched unrelated (MUD) HSCT using SIR combined with tacrolimus (TAC) and mini-methotrexate for GVHD prophylaxis at City of Hope. TMA was defined as SCr increase of ≥ 50% above baseline, LDH twice the institutional upper normal limit, presence of schistocytes or persistent presence of nucleated red blood cells, and prolonged or progressive thrombocytopenia (platelets <50 × 109/L or ≥ 50% decrease from previous count). A case series of 47 MUD-HSCT patients were included in this retrospective chart review study. The median age was 50 years (range: 19–67); (male/female: 28/19). Conditioning regimens consisted of fludarabine/melphalan (65%) and FTBI combined with cyclophosphamide or etoposide (35%). Diagnoses included ALL (32%), AML (25%), NHL (15%), MDS (15%), MPD (9%), CML (2%), CLL (2%). Twenty-six patients (55%) had a 10/10 matched (HLA-A, B, C, DRB1, and DQB1) donor by high-resolution on typing. The median follow up for the 30 surviving patients is 14.5 months (2.8–26). The one-year probabilities of overall survival and non-relapse mortality (NRM) were 61% and 19%, respectively. Grade II-IV acute GVHD (aGVHD) was reported in 60% of all patients (grade III-IV: 25%). Thirteen (28%) patients met the above diagnostic criteria for TMA. In addition, we included two patients who did not meet the criteria due to missing tests but were clinically diagnosed with TMA by independent attending physicians, resulting in the total incidence of 32% (15/47). Four of the 15 patients met the criteria for TMA as a result of ongoing multi-organ failure secondary to other causes. The median time to TMA onset was five weeks (2–20 weeks). Most cases (93%) occurred within the first 100 days post-HSCT. Thirteen patients developed both TMA and aGVHD, in which the majority of patients (70%) developed TMA after a diagnosis of aGVHD had been made. Initial treatments for TMA included holding TAC (33%), holding SIR (20%), holding or adjusting doses (27% and 20%, respectively) for both drugs. One patient underwent plasma exchange. Sixty percent of patients subsequently recovered from TMA as defined by normalization of laboratory values. Of the 17 expired patients, ten were diagnosed with TMA. Causes of death were as follows: for TMA cases, relapse mortality=3, NRM=7; for Non-TMA patients, relapse mortality=6, NRM=1. At the time of TMA diagnosis, the median TAC and SIR levels were 11.3 (0–18.8) and 7 (0–23.9) ng/ml, respectively, in contrast to the median TAC and SIR levels for non-TMA patients at 6.1 (p= 0.02) and 5.5 (p=0.13) ng/ml, respectively. To identify other possible risk factors for TMA, the following patient and treatment-related characteristics were examined: age, conditioning regimen, disease type, degree of HLA match, and exposure to triazole antifungals. Only higher tacrolimus levels (HR: 6.9, p<0.01) and aGVHD grades III-IV (HR: 3.5, p=0.02) were associated with an increased risk for TMA. In conclusion, TMA is common after MUD allo-HSCT using SIR-containing GVHD prophylaxis. The risk factors for TMA suggest that careful monitoring and adjustment of TAC/SIR dosages to avoid super-therapeutic levels is critical, particularly during ongoing GVHD.
