Abstract
INTRODUCTION This study aimed to evaluate the performance of the D-index, a calculated measure of neutropenic burden, in predicting the risk of invasive fungal infections (IFIs) in acute myeloid leukemia (AML) patients. METHODS A retrospective study of adult AML patients who received the first induction chemotherapy and developed febrile neutropenia was conducted. Clinical characteristics, laboratory data, and the calculation of the D-index and cumulative D-index (c-D-index) were collected and analyzed between patients with and without IFIs. RESULTS A total of 101 patients were included, with 16 (15.8%) patients who developed IFIs. Clinical characteristics, antifungal prophylaxis, and AML cytogenetic risk were similar between patients with or without IFIs. The results showed that the D-index and c-D-index were more effective in predicting IFIs than the duration of neutropenia. With the D-index cutoff of 7083, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 81.3%, 83.5%, 48.2%, and 95.9%, respectively. c-D-index at 5625 revealed sensitivity, specificity, PPV, and NPV for IFIs of 68.8%, 68.2%, 28.9%, and 92.1%, respectively. Using this cutoff of c-D-index, patients without IFIs were overtreated with an antifungal regimen in 45 (52.9%) cases. CONCLUSION The D-index and c-D-index were helpful indicators for defining the risk of IFIs in AML patients with febrile neutropenia.

Kubo H, Imataki O, Kubo YH, Uemura M. c-D-index at day 11 can predict febrile neutropenia during chemotherapy in acute myeloid leukemia. PLoS One 2022; 17:e0263623. [PMID: 35298471 PMCID: PMC8929597 DOI: 10.1371/journal.pone.0263623] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Accepted: 01/22/2022] [Indexed: 11/19/2022] Open
Abstract
Acute myeloid leukemia (AML) often requires long-term intensive chemotherapy for its cure. During chemotherapy, the patient always experiences neutropenia with readings below 500 cells/μL; this is often accompanied by pyrexia with a temperature of more than 101°F. This combination of neutropenia and fever is called febrile neutropenia (FN). A tool to sum up the daily severity of a patient’s neutropenia, the “D-index,” has been validated in some specific clinical settings. In this study, we examined whether the D-index is a useful predictor of the onset of FN. We recruited consecutive patients treated with induction and consolidation chemotherapy for newly diagnosed AML. We gathered all the FN events and their clinical background data retrospectively. Patients’ background, such as pre-existing conditions and disease status before the treatment, were analyzed using multivariate methods. All FN events during chemotherapy were evaluated for infection focus and causative organism. A total cohort of 51 cases (25 women, 26 men; median age 51 years, range 18–74) was analyzed. They displayed 171 neutropenic events (115 FN and 56 afebrile episodes) during chemotherapy, and complete neutropenic events were used in this study. Sensitivity and specificity analysis showed that the most useful cutoff value to predict the onset of FN was a cumulative D-index at day 11 (c-D11-index) of 718. The cumulative incidence of FN during chemotherapy was significantly higher in the group with c-D11-index ≥710 (80%) than in the group with c-D11-index <710 (39%) (P < 0.0001). Through multivariate analysis, the presence of diabetes mellitus and the c-D11-index were extracted as contributing factors to the onset of FN (P = 0.0087 and 0.0002, respectively). In conclusion, we can predict that AML patients receiving chemotherapy will experience the complication of FN when the c-D-index at day 11 is >710, with an odds ratio of 2.1.

Vijayvargiya P, Lara Abad C, Esquer Garrigos Z, O'Horo JC, Walker RC, Hogan WJ, Tande AJ. D-index as a marker of bloodstream infections in patients with allogeneic hematopoietic stem cell transplantation. Transpl Infect Dis 2021; 23:e13588. [PMID: 33590904 DOI: 10.1111/tid.13588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 01/31/2021] [Accepted: 02/07/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Neutropenia is a risk factor for development of infections; however, the direct effect of neutropenia on development of bloodstream infection (BSI) is not known. D-index, which is area between the neutrophil time curve and a neutrophil count of 0.5 × 109 /L, incorporates the combined effect of severity and duration of neutropenia. We aimed to evaluate whether D-index can be used as a marker for BSI in patients with allogeneic stem cell transplantation. METHOD We conducted a retrospective cohort study of patients undergoing allogeneic stem cell transplantation between January 1, 2005, and September 30, 2015. The primary outcome measure was the development of BSI within 30 days of transplantation. RESULTS A total of 714 patients were included in the study of whom 101 developed BSI. Patients with BSI had a significantly higher median D-index value compared with patients who did not have BSI (4990 vs. 3570, P < .001). As a marker, the performance of the D-index was similar to that of the duration of profound neutropenia (P = .18) and significantly better than the total duration of neutropenia (P = .001). CONCLUSION The D-index performed better than the total duration of neutropenia as a marker for BSI in patients with allogeneic stem cell transplantation. There was no difference between D-index and, a more easily calculable indicator, duration of profound neutropenia.

Impact of neutropenia evaluated in terms of the D-index on invasive fungal disease while on empiric or preemptive antifungal treatment strategy in the early phase after allogeneic hematopoietic stem cell transplantation. Transpl Infect Dis 2020; 22:e13409. [PMID: 32654234 DOI: 10.1111/tid.13409] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Revised: 06/20/2020] [Accepted: 07/05/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND We retrospectively evaluated the association between the D-index, which reflects both the depth and duration of neutropenia, and proven/probable invasive fungal disease (IFD) early after allogeneic hematopoietic stem cell transplantation (HSCT) at our center (n = 394). METHODS The D-index was defined as the area over the neutrophil curve during neutropenia. The cumulative D-index from the start of neutropenia until the development of infection (c-D-index) was also evaluated as a real-time assessment of neutropenia. RESULTS There were 19 cases of early proven/probable IFD before and within 1 week after engraftment. Fifteen cases (78.9%) were seen as breakthrough infection while on empiric (n = 7), preemptive (n = 4) or prophylactic (n = 4) antifungal administration with mold-active agents. The c-D-index and lower performance status were identified as independent significant predictive factors for IFD. A receiver operating characteristic (ROC) curve analysis showed that the D-index and c-D-index were more accurate than the simple duration of neutropenia and as accurate as the duration of profound neutropenia for predicting IFD. The sensitivity, specificity, and positive and negative predictive values of the c-D-index using an appropriate cutoff (CO) value (10 644) determined by ROC curve analysis were 73.1%, 63.2%, 9.1%, and 97.9%, respectively. The advantage of the c-D-index to cumulative days of neutropenia in terms of positive and negative predictive values seemed to be small. CONCLUSIONS The appropriate CO value for the c-D-index for predicting IFD was as high as 10 644 in allogeneic HSCT with a more frequent use of empiric antifungal therapy. The c-D-index is useful for assessing the risk of breakthrough IFD.
