RESUMO
Incidences of diseases treated with transplantation frequently peak at higher age. The contribution of age to total risk of transplantation has not been estimated amidst an aging society. We compare outcomes of 1,547 patients aged 70-79 years and 9,422 patients aged 60-69 years transplanted 1998-2018 for myeloid, lymphoid and further neoplasia in Germany. To quantify the contribution of population mortality to survival, we derive excess mortality based on a sex-, year- and agematched German population in a multistate model that incorporates relapse and graft-versus-host-disease (GvHD). Overall survival, relapse-free survival (RFS) and GvHD-free-relapse-free survival (GRFS) is inferior in patients aged 70-79 years, compared to patients aged 60-69 years, with 36% (95% Confidence Interval [CI]: 34-39%) versus 43% (41-44%), 32% (30- 35%) versus 36% (35-37%) and 23% (21-26%) versus 27% (26-28%) three years post-transplant (P<0.001). Cumulative incidences of relapse at three years are 27% (25-30%) for patients aged 70-79 versus 29% (29-30%) (60-69 years) (P=0.71), yet the difference in non-relapse mortality (NRM) (40% [38-43%] vs. 35% [34-36%] in patients aged 70-79 vs. 60-69 years) (P<0.001) translates into survival differences. Median OS of patients surviving >1 year relapse-free is 6.7 (median, 95% CI: 4.5-9.4, 70-79 years) versus 9 (8.4-10.1, 60-69 years) years since landmark. Three years after RFS of one year, excess NRM is 14% (95% CI: 12-18%) in patients aged 70-79 versus 12% [11-13%] in patients aged 60-69, while population NRM is 7% (6-7%) versus 3% (3-3%). Mortality for reasons other than relapse, GvHD, or age is as high as 27% (24-29%) and 22% (22-23%) four years after transplantation. In conclusion, survival amongst older patients is adequate after allogeneic stem cell transplantation.

Azacitidine (Aza) combined with donor lymphocyte infusions (DLI) is an established treatment for relapse of myeloid malignancies after allogeneic transplantation. Based on its immunomodulatory and anti-leukemic properties we considered Lenalidomide (Lena) to act synergistically with Aza/DLI to improve outcome. We, therefore, prospectively investigated tolerability and efficacy of this combination as first salvage therapy for adults with post-transplant relapse of acute myeloid leukemia, myelodysplastic syndromes and chronic myelomonocytic leukemia. Patients were scheduled for eight cycles Aza (75 mg/m2 day 1-7), Lena (2.5 or 5 mg, days 1-21) and up to three DLI with increasing T-cell dosages (0.5×106-1.5×107 cells/kg). Primary endpoint was safety, while secondary endpoints included response, graft-versus-host disease (GvHD) and overall survival (OS). Fifty patients with molecular (52%) or hematological (48%) relapse of myelodysplastic syndromes (n=24), acute myeloid leukemia (n=23) or chronic myelomonocytic leukemia (n=3) received a median of seven (range, 1-8) cycles including 14 patients with 2.5 mg and 36 with 5 mg Lena daily dosage. Concomitantly, 34 patients (68%) received at least one DLI. Overall response rate was 56% and 25 patients (50%) achieved complete remission being durable in 80%. Median OS was 21 months and 1-year OS rate 65% with no impact of type of or time to relapse and Lena dosages. Treatment was well tolerated indicated by febrile neutropenia being the only grade ≥3 non-hematologic adverse event in >10% of patients and modest acute (grade 2-4 24%) and chronic (moderate/severe 28%) GvHD incidences. In summary, Lena can be safely added to Aza/DLI without excess of GvHD and toxicity. Its significant anti-leukemic activity suggests that this combination is a novel salvage option for post-transplant relapse (clinicaltrials gov. Identifier: NCT02472691).

PURPOSE: Multiple myeloma (MM) is a severe hemato-oncological disease with high mortality and increasing incidence rate. Since evidence on exercise therapy in MM patients remains limited, this study examines feasibility, adherence, and efficacy based on real-life data from an oncologic care structure. METHODS: A data evaluation of MM patients who participated in the oncologic exercise and movement therapy (OTT) at the Cologne University Hospital between 2012 and 2019 was conducted. The patient flow was incrementally reduced to four cohorts, intention-to-treat cohort (ITTC), safety cohort (SC), adherence cohort (AC), and efficacy cohort (EC). Cohorts were evaluated descriptively and by means of correlation analysis as well as group and time comparisons. RESULTS: Thirty patients registered at the OTT between 2012 and 2019 (ITTC). The SC (N = 26) attended exercise therapy on average about one session per week over a period of 8 months. One-third dropped out within 3 months. In the AC (N = 15), BMI at baseline exhibited a strong and very significant negative correlation with exercise adherence. In the EC (N = 8), a significant improvement in physical functioning and a tendency towards significance in fatigue reduction between two measurement points was observed. No adverse events were documented. CONCLUSIONS: The present observatory study reveals safety and feasibility while indicating adherence and efficacy of exercising MM patients under real-life therapy circumstances. Found obstacles to exercising as well as improvements in questionnaire scale scores need to be further examined in confirmatory study designs.

BACKGROUND: Lower respiratory tract infections are among the main causes of death. Although there are many respiratory viruses, diagnostic efforts are focused mainly on influenza. The Respiratory Viruses Network (RespVir) collects infection data, primarily from German university hospitals, for a high diversity of infections by respiratory pathogens. In this study, we computationally analysed a subset of the RespVir database, covering 217,150 samples tested for 17 different viral pathogens in the time span from 2010 to 2019. METHODS: We calculated the prevalence of 17 respiratory viruses, analysed their seasonality patterns using information-theoretic measures and agglomerative clustering, and analysed their propensity for dual infection using a new metric dubbed average coinfection exclusion score (ACES). RESULTS: After initial data pre-processing, we retained 206,814 samples, corresponding to 1,408,657 performed tests. We found that Influenza viruses were reported for almost the half of all infections and that they exhibited the highest degree of seasonality. Coinfections of viruses are frequent; the most prevalent coinfection was rhinovirus/bocavirus and most of the virus pairs had a positive ACES indicating a tendency to exclude each other regarding infection. CONCLUSIONS: The analysis of respiratory viruses dynamics in monoinfection and coinfection contributes to the prevention, diagnostic, treatment, and development of new therapeutics. Data obtained from multiplex testing is fundamental for this analysis and should be prioritized over single pathogen testing.

Patients undergoing allogeneic stem cell transplantation (allo-SCT) are given a real chance of cure, but at the same time are confronted with a considerable risk of mortality and of severe long-term impediments. This narrative, non-systematic literature review aims to describe the supportive and palliative care needs of allo-SCT recipients, including long-term survivors or those relapsing or dying after transplantation. It also evaluates the feasibility and effectivity of integrating palliative care early in transplant procedures. In this appraisal of available literature, the main findings relate to symptoms like fatigue and psychological distress, which appear to be very common in the whole allo-SCT trajectory and might even persist many years post-transplantation. Chronic GvHD has a major negative impact on quality of life. Overall, there is a paucity of research on further issues in the context of allo-SCT, like the distress related to the frequently unpredictable post-transplant trajectory and prognosis, as well as the end-of-life phase. First randomized controlled results support the effectiveness of early integration of specialized palliative care expertise into transplant algorithms. Barriers to this implementation are discussed.

RATIONALE: Steroid refractory graft-vs-host disease (sr-GvHD) represents a challenging complication after allogeneic hematopoietic cell transplantation (allo-HCT). Intestinal microbiota (IM) diversity and dysbiosis were identified as influencing factors for the development of acute GvHD. Fecal microbiota transfer (FMT) is hypothesized to restore IM dysbiosis, but there is limited knowledge about the significance of FMT in the treatment of sr-GvHD. OBJECTIVES: We studied the effects of FMT on sr-GvHD in allo-HCT patients from two German tertiary clinical centers (n = 11 patients; period: March 2017 until July 2019). To assess safety and clinical efficacy, we analyzed clinical data pre- and post-FMT (day -14 to +30 relative to FMT). Moreover, IM were analyzed in donor samples and in a subset of patients pre- and post-FMT by 16S rRNA sequencing. RESULTS: Post-FMT, we observed no intervention-associated, systemic inflammatory responses and only minor side effects (5/11 patients: abdominal pain and transformation of peristalsis-each 3/11 and vomiting-1/11). Stool frequencies and volumes were significantly reduced [pre- vs post-FMT (d14): P < .05, respectively] as well as clear attenuation regarding both grading and staging of sr-GvHD was present upon FMT. Moreover, IM analyses revealed an increase of alpha diversity as well as a compositional shifts toward the donor post-FMT. CONCLUSIONS: In our study, we observed positive effects on sr-GVHD after FMT without the occurrence of major adverse events. Although these findings are in line with published data on beneficial effects of FMT in sr-GvHD, further randomized clinical studies are urgently needed to better define the clinical validity including mode of action.

OBJECTIVE: Fluconazole or posaconazole is a standard of care in antifungal prophylaxis for patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). However, many patients need to interrupt standard prophylaxis due to intolerability, drug-drug interactions, or toxicity. Micafungin has come to prominence for these patients. However, the optimal biological dose of micafungin stays unclear. METHODS: We retrospectively evaluated the efficacy of micafungin as antifungal prophylaxis in HSCT patients. Micafungin was applied as bridging in patients who were not eligible to receive oral posaconazole. Micafungin was either given at a dose of 100 mg or 50 mg SID. RESULTS: A total of 173 patients received micafungin prophylaxis, 62 in the 100 mg and 111 in the 50 mg dose group. The incidence of probable or proven breakthrough IFDs during the observation period was one in the 100 mg and one in the 50 mg group. Fungal-free survival after 100 days was 98% and 99% (P = .842), and overall survival after 365 days was 60% and 63% (P = .8) respectively. In both groups, micafungin was well tolerated with no grade 3 or 4 toxicities. CONCLUSION: In this retrospective analysis, which was not powered to detect non-inferiority, micafungin is effective and complements posaconazole as fungal prophylaxis in HSCT.

The neuropeptide CGRP, acting through the G-protein coupled receptor CALCRL and its coreceptor RAMP1, plays a key role in migraines, which has led to the clinical development of several inhibitory compounds. Recently, high CALCRL expression has been shown to be associated with a poor prognosis in acute myeloid leukemia (AML). We investigate, therefore, the functional role of the CGRP-CALCRL axis in AML. To this end, in silico analyses, human AML cell lines, primary patient samples, and a C57BL/6-based mouse model of AML are used. We find that CALCRL is up-regulated at relapse of AML, in leukemic stem cells (LSCs) versus bulk leukemic cells, and in LSCs versus normal hematopoietic stem cells. CGRP protects receptor-positive AML cell lines and primary AML samples from apoptosis induced by cytostatic drugs used in AML therapy, and this effect is inhibited by specific antagonists. Furthermore, the CGRP antagonist olcegepant increases differentiation and reduces the leukemic burden as well as key stem cell properties in a mouse model of AML. These data provide a basis for further investigations into a possible role of CGRP-CALCRL inhibition in the therapy of AML.

Acquired immunoglobulin G (IgG)-mediated thrombotic thrombocytopenic purpura (TTP) has not yet been described in non-twin siblings. We report two cases of acquired TTP in Caucasian sisters with inactive ADAMTS13 metalloprotease due to ADAMTS13 autoantibodies suggesting a role of genetic determinants in this life-threatening disease. However, human leucocyte antigen (HLA) class II types presumably associated with acquired TTP were not identified in the patients, indicating that HLA class II typing may not be useful in acquired TTP risk assessment of family members.

BACKGROUND: Intravenous bridging strategies increase exposure of antifungal prophylaxis in high-risk hematological patients. The cost-effectiveness of such strategies has not been analyzed. METHODS: A recent study compared the impact of oral posaconazole (POS) and oral posaconazole with intravenous micafungin bridging (POS-MIC) as prophylactic antifungal regimens in patients undergoing allogeneic stem cell transplantation (aSCT). Based on data from the Cologne Cohort of Neutropenic Patients (CoCoNut), a health economic evaluation of direct treatment costs was performed to analyze the economic impact of micafungin bridging. Analysis was undertaken based on current guidelines for the German societal perspective with an annual discount rate of 5%, whereby indirect costs were disregarded due to the severity of the underlying disease. Sensitivity analysis of cost calculation with different discount rates was performed to improve robustness of our health economic evaluation. RESULTS: A retrospective case-control analysis of patients undergoing aSCT between 05/2006 and 07/2011 was performed; 106 patients each in the POS and POS-MIC group were included. In the POS and POS-MIC group, mean costs per patient for the treatment on bone marrow transplant ward were 27,228 (95% CI: 24,932-29,525) vs. 27,894 (95% CI: 26,414-29,375; P = 0.629), for diagnostic measures 2124 (95% CI: 1823-2425) vs. 1269 (95% CI: 1168-1370; P ≤ 0.001), for laboratory findings 10,612 (95% CI: 9681-11,544) vs. 8836 (95% CI: 8198-9475; P = 0.002), and for overall antifungal treatment 6105 (95% CI: 4703-7508) vs. 6943 (95% CI: 5393-8493; P = 0.428), resulting in mean overall costs per patient of 60,304 (95% CI: 53,969-66,639) vs. 58,089 (95% CI: 51,736-64,442; P = 0.625). CONCLUSIONS: Our health economic evaluation shows micafungin bridging in aSCT patients did not result in excess cost. Higher acquisition costs of antifungal prophylaxis were balanced by a reduced incidence of possible IFD and lower costs for empirical, preemptive, and targeted antifungal therapy as well as lower costs for diagnostic measures and laboratory tests in the micafungin bridging group.

Chimeric antigen receptor T cell (CAR T) therapy is a potent treatment for relapsed/refractory (r/r) B cell lymphomas but provides lasting remissions in only â¼40% of patients and is associated with serious adverse events. We identify an upregulation of CD80 and/or CD86 in tumor tissue of (r/r) diffuse large B cell lymphoma (DLBCL) patients treated with tisagenlecleucel. This finding leads to the development of the CAR/CCR (chimeric checkpoint receptor) design, which consists of a CD19-specific first-generation CAR co-expressed with a recombinant CTLA-4-linked receptor with a 4-1BB co-stimulatory domain. CAR/CCR T cells demonstrate superior efficacy in xenograft mouse models compared with CAR T cells, superior long-term activity, and superior selectivity in in vitro assays with non-malignant CD19+ cells. In addition, immunocompetent mice show an intact CD80-CD19+ B cell population after CAR/CCR T cell treatment. The results reveal the CAR/CCR design as a promising strategy for further translational study.

INTRODUCTION: Although allogeneic stem cell transplantation (allo-SCT) is a curative treatment for many haematological malignancies, it is often associated with a high morbidity and mortality. Yet, little is known about the needs for supportive and palliative care among allo-SCT recipients. Moreover, targeted interventions that reduce symptom burden and suffering are still lacking. The present study aims to inform a supportive-palliative care intervention for patients with allo-SCT and their informal carers by exploring their experience and assessing their needs, especially their existential concerns, regarding four research topics: symptom burden and quality of life; coexistence of a chance for cure and a relevant risk of dying; change in goals of care; dying phase. METHODS AND ANALYSIS: This is a descriptive mixed-methods study in progress with a convergent parallel design. Data on the four research topics will be collected and analysed separately in three steps: (1) qualitative semi-structured interviews among 20 patients, 20 informal carers and 12 healthcare providers (HCPs) and focus groups among 12-24 HCPs; (2) a quantitative cross-sectional survey with validated questionnaires and self-developed questions among 100 patients, 100 informal carers and 50 HCPs; (3) a retrospective case analysis of all deceased patients who underwent an allo-SCT between 2010 and 2019, with collection of quantitative and qualitative data. The qualitative and quantitative data sets will be finally merged for comparison and interpretation. Results will serve to develop a supportive-palliative care intervention. ETHICS AND DISSEMINATION: The Ethics Commission of the Faculty of Medicine of the University of Cologne approved this study (20-1370_2). The study results will be published in peer-review journals, be presented at congresses and will be translated into clinical practice through the development of the palliative-supportive care intervention. TRIAL REGISTRATION NUMBER: DRKS00027290 (German Clinical Trials Register).

Background: Immunotherapeutic targets in multiple myeloma (MM) have variable expression height and are partly expressed in subfractions of patients only. With increasing numbers of available compounds, strategies for appropriate choice of targets (combinations) are warranted. Simultaneously, risk assessment is advisable as patient's life expectancy varies between months and decades. Methods: We first assess feasibility of RNA-sequencing in a multicenter trial (GMMG-MM5, n=604 patients). Next, we use a clinical routine cohort of untreated symptomatic myeloma patients undergoing autologous stem cell transplantation (n=535, median follow-up (FU) 64 months) to perform RNA-sequencing, gene expression profiling (GEP), and iFISH by ten-probe panel on CD138-purified malignant plasma cells. We subsequently compare target expression to plasma cell precursors, MGUS (n=59), asymptomatic (n=142) and relapsed (n=69) myeloma patients, myeloma cell lines (n=26), and between longitudinal samples (MM vs. relapsed MM). Data are validated using the independent MMRF CoMMpass-cohort (n=767, FU 31 months). Results: RNA-sequencing is feasible in 90.8% of patients (GMMG-MM5). Actionable immune-oncological targets (n=19) can be divided in those expressed in all normal and >99% of MM-patients (CD38, SLAMF7, BCMA, GPRC5D, FCRH5, TACI, CD74, CD44, CD37, CD79B), those with expression loss in subfractions of MM-patients (BAFF-R [81.3%], CD19 [57.9%], CD20 [82.8%], CD22 [28.4%]), aberrantly expressed in MM (NY-ESO1/2 [12%], MUC1 [12.7%], CD30 [4.9%], mutated BRAF V600E/K [2.1%]), and resistance-conveying target-mutations e.g., against part but not all BCMA-directed treatments. Risk is assessable regarding proliferation, translated GEP- (UAMS70-, SKY92-, RS-score) and de novo (LfM-HRS) defined risk scores. LfM-HRS delineates three groups of 40%, 38%, and 22% of patients with 5-year and 12-year survival rates of 84% (49%), 67% (18%), and 32% (0%). R-ISS and RNA-sequencing identify partially overlapping patient populations, with R-ISS missing, e.g., 30% (22/72) of highly proliferative myeloma. Conclusion: RNA-sequencing based assessment of risk and targets for first choice treatment is possible in clinical routine.

T cells modified for expression of Chimeric Antigen Receptors (CARs) were the first gene-modified cell products approved for use in cancer immunotherapy. CAR-T cells engineered with gammaretroviral or lentiviral vectors (RVs/LVs) targeting B-cell lymphomas and leukemias have shown excellent clinical efficacy and no malignant transformation due to insertional mutagenesis to date. Large-scale production of RVs/LVs under good-manufacturing practices for CAR-T cell manufacturing has soared in recent years. However, manufacturing of RVs/LVs remains complex and costly, representing a logistical bottleneck for CAR-T cell production. Emerging gene-editing technologies are fostering a new paradigm in synthetic biology for the engineering and production of CAR-T cells. Firstly, the generation of the modular reagents utilized for gene editing with the CRISPR-Cas systems can be scaled-up with high precision under good manufacturing practices, are interchangeable and can be more sustainable in the long-run through the lower material costs. Secondly, gene editing exploits the precise insertion of CARs into defined genomic loci and allows combinatorial gene knock-ins and knock-outs with exciting and dynamic perspectives for T cell engineering to improve their therapeutic efficacy. Thirdly, allogeneic edited CAR-effector cells could eventually become available as "off-the-shelf" products. This review addresses important points to consider regarding the status quo, pending needs and perspectives for the forthright evolution from the viral towards gene editing developments for CAR-T cells.

BACKGROUND: The Federal Standardized Medication Plan (BMP) offers the possibility of providing patients with specific information on drug therapy. Cancer patients who are treated with oral anticancer drugs have a great need for information as they take the drugs independently in their home environment. Providing specific instructions for oral anticancer drugs may enhance the patient role and improve medication safety. METHODS: In a four-step process (needs assessment, compilation of the text modules, pilot and main phase), an oncologic addendum for the BMP was developed and subjected to an acceptance test. Also, a needs assessment was conducted with oncologists, pharmacists and patients to identify important information to be included in the oncologic addendum. Subsequently, the acceptability of the BMP including the addendum ('Onko-BMP') was tested among health care providers and patients in two study phases (pilot and main phase). Updates made to the Onko-BMP were documented at each follow-up visit. At the end of the observation period, discrepancies between a brown bag review and the latest Onko-BMP were identified to evaluate its completeness. In addition, acceptance of the Onko-BMP was analyzed using qualitative methods. At the end of the pilot phase the patients were interviewed and completed a questionnaire at the end of the main phase. Focus interviews and a focus group were conducted with the health care providers. RESULTS: A total of 347 health care providers and cancer patients participated in the needs assessment, including 167 oncologists, 130 pharmacists, and 50 patients. Suggestions for additional information to be included in the oncologic addendum mainly included instructions for how to take the medication, therapy-limiting side effects as well as potentially relevant interactions with over-the-counter drugs. Ten patients participated in the pilot phase and 60 patients in the main phase of the project. The use of the Onko-BMP was positively evaluated by all participants. The majority of the 178 updates in the main phase were made by the patients themselves. Most frequently, missing items were added (62). After comparison with the brown bag at the end of the observation period, 175 discrepancies for a total of 270 products, including food supplements (mean 6.3⯱â¯3.9), and 245 drugs (mean 5.7⯱â¯3.1) taken by the patients were detected, 49 of which were due to missing drugs on the Onko-BMP, mainly on-demand medication (30). 82 documented discrepancies were for prescription drugs. In the qualitative surveys, health care providers indicated that there is a high need for the Onko-BMP. In particular, its use could strengthen the patient's role in therapy. The frequently missing or poor technical requirements for working with the BMP were perceived as limiting its widespread use. Assignment of clear responsibilities and remuneration of all professionals involved were identified as important influential factors for an efficient use of the Onko-BMP. Patients considered the added value of the Onko-BMP primarily to be in their being able to inform their treating physicians and pharmacists about their medication. CONCLUSIONS: The developed Onko-BMP gained a high level of acceptance among patients and health care providers. It can improve education about oral anticancer drugs and thereby strengthen the patient role. However, in order to ensure widespread use of the tool, the necessary conditions should be created on the part of the health care providers. In particular, the IT infrastructure for its use in daily routine needs to be improved in order to exploit its full potential and ensure its successful large-scale implemention.

There is no standard in hematopoietic stem cell transplantations (HSCT) for pre-transplant screening of psychosocial risk factors, e.g., regarding immunosuppressant non-adherence. The aim of this prospective study is to explore the predictive value of the pretransplant psychosocial screening instrument Transplant Evaluation Rating Scale (TERS) for mortality in a 3-year follow-up. Between 2012 and 2017 61 patients were included and classified as low (TERS = 26.5-29) and increased-risk group (TERS = 29.5-79.5). Both groups were compared regarding mortality until 36 months after transplantation and secondary outcomes [Medication Experience Scale for Immunosuppressants (MESI); incidence/grade of GvHD]. The increased-risk group (n = 28) showed significantly worse cumulative survival in the outpatient setting (from 3 months to 3 years after HSCT) [Log Rank (Mantel Cox) P = 0.029] compared to low-risk group (n = 29) but there was no significant result for the interval immediately after HSCT until 3 years afterwards. Pre-transplant screening with TERS contributes to prediction of survival after HSCT. The reason remains unclear, since TERS did not correlate with GvHD or MESI. The negative result regarding the interval immediately after HSCT until 3 years could be caused by the intensive in-patient setting with mortality which is explained rather by biological reasons than by non-adherence.
RESUMO
Graft-versus-host disease (GvHD) is a frequent, and often life-threatening, complication after an allogeneic, hematopoietic stem cell transplantation (allo-SCT). It can appear in an acute or a chronic form and presents different grades of severity. Particularly, the severe forms of GvHD are often responsible for a change of the curative intent for allo-SCT into a palliative goal of care. For this non-systematic review, we conducted a focused literature search in the MEDLINE database via PubMed to examine whether patients with severe forms of GvHD might have special needs and burdens from a supportive and palliative care perspective. To draw a comprehensive picture of this patient group, we included findings on quality of life (QoL) and physical symptoms and function as well as psychological and spiritual well-being. In most domains, patients with severe forms of GvHD showed greater impairment and a higher symptom burden compared to patients with milder forms of GvHD. However, we could not identify any studies that specifically investigated patients with severe forms of GvHD. Further research in this field is necessary to guarantee the highest standard of care for this very special patient group.
