Association between the kinetics of cytomegalovirus reactivation evaluated in terms of the area under the curve of cytomegalovirus antigenemia and invasive mold infection during the post-engraftment phase after allogeneic hematopoietic stem cell transplantation. Transpl Infect Dis 2020; 22:e13387. [PMID: 32585736 DOI: 10.1111/tid.13387] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Revised: 05/26/2020] [Accepted: 06/17/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND We evaluated the clinical impact of cytomegalovirus (CMV) reactivation calculated in terms of the area under the curve of CMV antigenemia (CMV-AUC) on the development of invasive mold infection (IMI) in the post-engraftment phase after allogeneic hematopoietic stem cell transplantation (HSCT). METHODS Among 394 consecutive patients who underwent their first allogeneic HSCT at our center between 2007 and 2018, 335 were included after excluding patients with a past history of invasive fungal disease (IFD), the development of IFD before engraftment, engraftment failure, or early death within 30 days. CMV antigenemia (CMV-AG) was monitored weekly after engraftment and 3 or more cells/2 slides were regarded as positive. CMV-AUC was calculated by the trapezoidal method using the number of CMV-AG after logarithmic transformation and the duration in weeks and was added until negative conversion. Patients with CMV reactivation were divided into low and high CMV-AUC groups using the median value of CMV-AUC as a threshold. RESULTS There were 17 proven/probable IMIs including one mucormycosis and 16 probable invasive aspergillosis, and the 2-year cumulative incidence was 1.0% in the negative CMV-AUC group (n = 136), 3.3% in the low CMV-AUC group (n = 98) and 13.8% in the high CMV-AUC group (n = 101) (P = .001). In a multivariate analysis, grade II-IV acute GVHD (HR 3.74) and CMV-AUC (HR low 1.25, high 5.91) were identified as independent significant factors associated with a higher incidence of IMI. CONCLUSIONS Cytomegalovirus kinetics evaluated in terms of CMV-AUC were significantly associated with the development of IMI in the post-engraftment phase after allogeneic HSCT.

Impact of the patient's body weight on the efficacy and adverse events of valganciclovir for cytomegalovirus reactivation after hematopoietic stem cell transplantation.

Abstract
While the dose of ganciclovir (GCV) is decided base on patients' body weight (BW), that of valganciclovir (VGCV) is fixed as 900 or 1800 mg/d regardless of the patient's BW in preemptive therapy for cytomegalovirus (CMV) reactivation in hematopoietic stem cell transplantation. We analyzed the impact of the patient's BW on the effectiveness and adverse events (AEs) of VGCV. From March 2004 to February 2017, 27 patients received VGCV as a first-line treatment for CMV reactivation. As a historical control group, we extracted 17 patients who started to receive GCV at a similar timing. We used the following definitions of outcomes: speed of reduction of CMV antigenemia (CMV-AG) as a measure of effectiveness, ratios of baseline and minimum value for white blood cell (WBC) and platelet counts, and ratio of baseline and maximum values for serum creatinine (sCr) as measures of AEs. As a result, there was no significant correlation between average daily dose of VGCV with or without adjusting for the patient's BW and speed of reduction of CMV-AG. On the other hand, the decreases in WBC and platelets and the increase in sCr were significantly correlated with the cumulative dose of VGCV. However, the absolute values of the correlation coefficients did not increase when we analyzed the correlations between the BW-adjusted cumulative dose of VGCV and factors associated with adverse events. There were no significant differences in efficacies or AE parameters between the GCV and VGCV groups. In conclusion, the patient's BW did not significantly affect the effectiveness or adverse events of VGCV.

Abstract
We prospectively validated the previously reported L-index, which reflects both the intensity and duration of lymphopenia, and further evaluated it using a lymphocyte subset analysis after allogeneic hematopoietic stem cell transplantation (HSCT) (n = 30). The L-index was defined as the area over the lymphocyte curve during lymphopenia (<700/μl), and calculated from the start of conditioning to day30 (L-index(30)) and day100 (L-index(100)). The lymphocyte subset including CD3, CD4, CD8, CD19 and CD56 was analyzed before and at 14, 21, 28, 42, 56, 70, and 84 days after HSCT. Cytomegalovirus (CMV) antigenemia was detected as >3 cells/2 slides by the C10/11 method in 21 cases (CMV-AG ≥3 group) at a median of 34 days. L-index(30) was significantly higher in the CMV-AG ≥3 group than in the CMV-AG <3 group (median 20,358 vs 17,235, P = .028). Recovery of the CD4+ and CD56+ cell counts between days 14 and 28 after HSCT was impaired in the CMV-AG ≥3 group. Regarding graft-versus-host disease (GVHD), grade II-IV acute GVHD was identified in 14 patients (GVHD group) at a median of 31 days. L-index(30) was significantly lower in the GVHD group (median 19,048 vs 22,256, P = .043). Recovery of CD3+ cells including both CD4+ and CD8+ cells between days 14 and 28 tended to be better in the GVHD group. In conclusion, L-index(30) was significantly associated with CMV reactivation and grade II-IV acute GVHD, but its clinical significance seemed to differ according to the results of a lymphocyte subset analysis.

Abstract
OBJECTIVE Although invasive fungal disease (IFD) is an important complication in allogeneic hematopoietic stem cell transplantation (HSCT), the clinical significance of surgery, including the role of surgical resection for persistent pulmonary fungal disease prior to allogeneic HSCT in the current era with a variety of available antifungal agents, is controversial. We investigated the role of surgical resection. METHODS We retrospectively investigated six patients who underwent surgical resection of suspected pulmonary fungal disease prior to allogeneic HSCT between April 2007 and June 2016 at our medical center. RESULTS We present six patients who underwent surgical resection of suspected pulmonary fungal disease prior to allogeneic HSCT. In our case series, three of four patients who were given a presurgical diagnosis of possible IFD were given a proven diagnosis after surgery, including two cases of invasive aspergillosis (IA) and one case of mucormycosis. All surgeries were performed by video-assisted thoracic surgery (VATS) for lobectomy without major complications. Recurrence of IFD was not observed after allogeneic HSCT in any of the six patients. CONCLUSION Our experience indicated that surgical resection of persistent localized pulmonary lesions of IFD before allogeneic HSCT was helpful for obtaining a definitive diagnosis and might be useful for reducing recurrence after HSCT.

Abstract
CD34-positive monocytes (CD34+mono) have recently been identified in grafts mobilized by granulocyte-colony stimulating factor. We analyzed transplant outcomes of 73 patients whose donor's peripheral blood cells were cryopreserved during mobilization. CD34+mono was detected more frequently in male donors (67% vs. 40%, P = 0.03), while the detection of CD34+mono in donors was not associated with the patient background. Although there was no significant difference in overall survival in the whole cohort, the detection of CD34+mono in donors were significantly associated with a decreased risk of non-relapse mortality (HR 0.23, P = 0.035). Fatal infectious events tended to be less frequent in donors with CD34+mono. Gene expression profile analyses of CD34+mono in humans revealed that the expressions of pro-inflammatory cytokines like IL6, CCL3, IL8, VEGFA, and IL1A were elevated in CD34+mono, and those cytokines were enriched in the immune response, especially against infectious pathogens in the gene ontology analyses. In addition, the expression of CD83 was specifically increased in CD34+mono. It might play a role of antigen presentation in the immune network, leading in a clinical benefit against infections. Further investigations will be required to confirm the biological functions and clinical roles of CD34+mono in transplantation.

Abstract
Myeloablative conditioning regimens are associated with severe gonadal toxicity. To preserve ovarian function, we have been investigating ovarian shielding during total body irradiation (TBI) with a myeloablative dose. In this report, we update the clinical outcomes. Female patients with standard-risk hematologic diseases, aged 40 years or younger, who desired to have children, were included (n = 19). The conditioning regimen consisted of TBI at 12 Gy with ovarian shielding and cyclophosphamide (120 mg/kg) or cytarabine (24 g/m2). Ovarian shielding reduced the actual irradiation dose applied to the ovaries from 12 Gy to 2 to 3 Gy. The median age at hematopoietic stem cell transplantation (HSCT) was 24 years (range, 19 to 33 years). With a median follow-up period of 1449 days (range, 64 to 3694) after HSCT, 5-year overall survival and 1- and 5-year relapse rates were 67%, 17%, and 31%, respectively. Only 2 of 14 patients with acute myeloid or lymphoid leukemia in remission have relapsed thus far. The 6-month and 1-year cumulative rates of menstrual recovery were 42% and 78%, respectively. In all patients with menstrual recovery, menstruation recovered within 1 year. The serum anti-Müllerian hormone (AMH) level tended to gradually increase after menstrual recovery. Three patients with extensive chronic graft-versus-host disease experienced delayed recovery of menstruation and serum AMH. Five pregnancies in 3 patients resulted in normal delivery in 1, selective cesarean operation in 1, current pregnancy in 1, and natural abortion in 2. These results suggest that a myeloablative TBI regimen with ovarian shielding could preserve fertility after HSCT without an apparent increase in relapse in standard-risk patients. Because serum AMH recovered gradually over time, the AMH level during the early phase after HSCT may have little value as a marker of ovarian reserve.

Abstract
Infection and inflammation can induce acute graft-vs.-host disease (aGVHD). We hypothesized that febrile neutropenia early after allogeneic hematopoietic cell transplantation (HCT) would increase the risk of aGVHD and non-relapse mortality (NRM). We retrospectively evaluated the impact of fever, C-reactive protein (CRP) concentration and blood stream infection (BSI) early after HCT on the incidence of grade II-IV aGVHD and NRM in 227 patients. Within 7 days after HCT, 91 (40.1%) patients experienced fever for at least 2 days (early-FN group). BSI occurred in 27 (11.9%) patients and the maximum CRP concentration was 2.57 mg/dl in the median. In a multivariate analysis, early-FN (hazard ratio (HR) 1.81, P = 0.007) and older recipient age (HR 1.68, P = 0.019) were significantly associated with the incidence of grade II-IV aGVHD. High-CRP and BSI were not significant risk factors for grade II-IV aGVHD. On the other hand, high-CRP was significantly associated with the incidence of NRM (HR 2.67, P = 0.004) in a multivariate analysis. In conclusion, although fever, CRP elevation and BSI are considered to be closely related events, they had different effects on the incidence of aGVHD and NRM. The development of early-FN after HCT may predict the risk of aGVHD.

Abstract
High-dose melphalan followed by autologous hematopoietic stem cell transplantation (ASCT) is a standard treatment for younger myeloma patients. However, the correlation between its toxicity and renal impairment is not clear. We analyzed this relationship, focusing on estimated glomerular filtration rate (eGFR) as an index of renal function. We evaluated 78 multiple myeloma patients who underwent ASCT following high-dose melphalan at our center. Patients were divided into a higher eGFR group (eGFR ≥ 60) and a lower eGFR group (eGFR < 60). Multivariate analyses revealed that lower eGFR was independently associated with alkaline phosphatase elevation (OR 10.2, P = 0.038), mucositis (OR 10.5, P = 0.032), grade 2-4 co-elevation of both aspartate aminotransferase and alanine aminotransferase (OR 21.3, P = 0.016), delay of reticulocyte engraftment (HR 0.524, P = 0.034), and delay of platelet engraftment (HR 0.535, P = 0.0016). However, lower eGFR was not correlated with overall survival or time-to-next treatment. In summary, renal dysfunction secondary to administration of high-dose melphalan was associated with increased hepatic and mucosal toxicity and delay of hematological recovery, but did not affect survival outcomes.

Abstract
The actual heparin concentration of harvested allogeneic bone marrow varies among harvest centers. We monitor the activated partial thromboplastin time (APTT) of the patient during bone marrow infusion and administer prophylactic protamine according to the APTT. We retrospectively reviewed the charts of consecutive patients who underwent bone marrow transplantation without bone marrow processing at our center between April 2007 and March 2016 (n = 94). APTT was monitored during marrow transfusion in 52 patients. We analyzed the relationship between the APTT ratio and several parameters related to heparin administration. As a result, the weight-based heparin administration rate (U/kg/hour) seemed to be more closely related to the APTT ratio (r = .38, P = .005) than to the total amount of heparin. There was no significant correlation between the APTT ratio and renal or liver function. Bleeding complications during and early after infusion were seen in 3 of 52 patients, and included intracranial, nasal, and punctured-skin bleeding. The APTT ratio during transfusion was over 5.88 in the former 2 patients and 2.14 in the latter. All of these patients recovered without sequelae. In conclusion, slow bone marrow infusion is recommended to decrease the weight-based heparin administration rate when the heparin concentration per patient body weight is high.

Abstract
BACKGROUND Consensus has yet to be reached regarding secondary prophylaxis in allogeneic hematopoietic stem cell transplantation (HSCT) with a complete resolution of invasive aspergillosis (IA) confirmed by chest computed tomography (CT). METHODS We retrospectively evaluated the feasibility of antifungal prophylaxis with fluconazole in allogeneic HSCT recipients who had previously developed IA which showed complete resolution as confirmed by chest CT before HSCT. Consecutive adult patients who underwent allogeneic HSCT at our institution and who had received fluconazole as systemic antifungal prophylaxis from June 2007 to January 2015 were included. We compared the clinical outcomes between patients with a past history of IA who showed a complete resolution of chest CT abnormalities (n = 13) and those without a previous history of IA (n = 137). RESULTS The cumulative incidence of proven or probable IA was 8.8% in the group without a past history of IA and 0.0% in the group with a past history of IA (p = .268). The cumulative incidence of proven or probable invasive fungal disease (IFD) within 100 days after allogeneic HSCT was 10.9% in the group without a past history of IA and 15.4% in the group with a past history of IA (p = .647). Fluconazole was switched to anti-mould agents in two-thirds of the patients in each group by day 100 after HSCT. CONCLUSIONS Fluconazole was confirmed to be an acceptable prophylactic agent early after allogeneic HSCT in appropriately selected patients.

Abstract
Peripheral T-cell lymphomas (PTCLs) are a rare and heterogeneous group of non-Hodgkin lymphomas, often resulting in poor prognoses. The CHOP chemotherapy regimen, which includes cyclophosphamide, doxorubicin, vincristine and prednisone, has been used previously to treat other types of lymphomas. Here, we examined the efficacy and safety of a dose-intensified CHOP regimen (Double-CHOP), which was followed by autologous stem-cell transplantation (ASCT) or high-dose methotrexate (HDMTX), in PTCL patients. Twenty-eight PTCL patients, who received 3 courses of Double-CHOP at our institution, were retrospectively studied from 1996 to 2012. Patients with anaplastic lymphoma kinase-positive anaplastic large-cell lymphoma (ALK+-ALCL) were excluded from this study. The median age of patients was 58 years (range: 17-69). They had low-intermediate (n=11), high-intermediate (n=10) or high (n=7) risk according to the International Prognostic Index (IPI). The overall complete remission (CR) rate following Double-CHOP treatment was 68%. Of the CR patients, 10 successfully tolerated a consolidated high-dose chemotherapy followed by ASCT and 7 received HDMTX. A single case of treatment-related mortality was recorded during the study. On a median 31-month follow-up, the estimated 3- or 5-year overall survival (OS) rates were 68 or 63%, respectively, while 3- or 5-year relapse-free survival (RFS) rates after CR were 60 or 43%, respectively. Although this study included elderly and excluded low-risk IPI and ALK+-ALCL patients, OS results were superiorly favourable, indicating the efficacy of this Double-CHOP regimen. However, an effective treatment strategy for refractory or relapsing patients needs to be validated and established.

Abstract
The present study deals with the first isolation of Exophiala dermatitidis from a dog. The dog had a history of multicentric lymphoma for 4 months. On physical examination, 10-15 black or purple subcutaneous nodules were detected on the dorsum of the right neck. Microscopic examination of biopsy specimen from the nodules disclosed lymphocytes, neutrophils and moniliform hyphae. The colony of the clinical isolate was flat with black aerial hyphae and a wet margin after 2 weeks incubation on Sabouraud's dextrose agar at 27 degrees C. The microscopic examination of the clinical isolate revealed that hyphae were brown, septate, and smooth, producing branched or unbranched conidiospores laterally or on the apex. The conidia were one celled, subglobose, elliptical to cylindrical, smooth and hyaline. Nucleotide sequence analysis of the chitin synthase 2 (CHS2) gene fragments from the isolate and a reference strain of E. dermatitidis showed more than 99% similarity.

Abstract
We have isolated and characterized a Neurospora crassa cytoplasmic ribosomal protein gene, named crp-7, which is found upstream of the photolyase gene. The deduced amino-acid sequence of this gene is highly homologous to the YS25 ribosomal protein of Saccharomyces cerevisiae. The crp-7 ORF consists of two exons which are separated by a short intron. The deduced polypeptide contains 87 amino acid residues and has a calculated molecular weight of 9.7 kDa. RFLP mapping showed that the crp-7 gene is located on the right arm of linkage group I. Southern blot hybridization analyses indicated that there is only one copy of the crp-7 gene in the N. crassa genome. Transcriptional elements, the Dde box, the Taq box and the CG element, that have been identified in other N. crassa ribosomal protein genes are observed in the promoter region of the crp-7 gene. The crp-7 mRNA levels were low in conidia and highest in young mycelia during vegetative growth. The mRNA levels of four r-protein genes, including the crp-7 gene, as well as the tef-1 gene encoding translational elongation factor 1 alpha, were raised following the treatment of mycelia with a low concentration of cycloheximide. This indicates that the expression of r-protein genes is under the control of so-called super-induction.

Abstract
Rapid progress in molecular technologies has enabled the detection of several oncogenic viruses in various types of tumors. The pathogenesis of Hodgkin's disease is suggested to have a strong association with Epstein-Barr virus (EBV). However, Hodgkin's disease related to EBV shows a wide geographic variation in epidemiology. These variations among different populations suggest an interaction of environmental factors and a direct role of EBV infection. Therefore, we performed a comparative study on epidemiologic, histologic, and virologic features of Hodgkin's disease among those in the western part of Kenya and in Nagasaki, Japan. The age distribution of Hodgkin's disease showed a distinct peak in the 0-9-year-old age group in Kenya, and a higher and lower peak in the 60-69- and 30-39-year-old age groups, respectively, in Japan. The most common subtype of Hodgkin's disease in both countries was mixed cellularity, followed by nodular sclerosis, lymphocyte depletion, and lymphocyte predominance. Mixed cellularity showed a significantly high prevalence among Kenyan children nine years of age or younger. Using the in situ hybridization method, EBV-encoded RNA (EBER-1) was detected in 79% of the Kenyan cases and 59% of the Japanese cases, with the mixed cellularity subtype showing a strong correlation with EBER-1. There was 100% positivity in both countries in those less than nine years old. These results suggest that EBV plays a more direct role in the pathogenesis of Hodgkin's diseases in Kenya, especially in cases among young children and also in Japanese children. Environmental and/or genetic factors may have a role, in addition to EBV, in the pathogenesis of Hodgkin's disease, especially in Nagasaki, Japan.
