  abstract  = {Dendritische Zellen stellen eine Gruppe morphologisch, ph{\"a}notypisch und funktionell einzigartiger Leukozyten dar, die eine zentrale Rolle bei der Regu-lation des Immunsystems spielen. Als die mit Abstand effektivsten antigen-pr{\"a}sentierenden Zellen besteht ihre Funktion sowohl in der Ausl{\"o}sung als auch in der Verhinderung spezifischer Immunantworten, wobei diese F{\"a}higkeiten von ihrem jeweiligen Reifungsstadium abh{\"a}ngig sind. In der vorliegenden Arbeit wurden Dendritische Zellen aus Milzen von M{\"a}usen verschiedener Linien mit¬tels Dichtegradientenzentrifugation unter Verwendung von OptiPrep (Iodixanol) isoliert und ph{\"a}notypisch sowie funktionell charakterisiert. Die gewonnenen Zellsuspensionen bestanden durchschnittlich zu 41 Prozent aus residenten konventionellen Dendritischen Zellen. Die isolierten Dendritischen Zellen waren unabh{\"a}ngig von der untersuchten Mauslinie bis zu 26 Prozent CD8α-positiv und bis zu 81 Prozent CD8α-negativ. Dendritische Zellen wiesen unmittelbar nach der Zellgewinnung einen unreifen Ph{\"a}notyp auf mit starker Expression von MHC-Klasse-II, aber schwacher bis fehlender Expression der kostimulato¬rischen Molek{\"u}le CD80, CD86 und CD40. Eine 24- bzw. 48-st{\"u}ndige Kulti¬vierung in vitro f{\"u}hrte zur Reifung der Dendritischen Zellen mit Zunahme der Expression von MHC-Klasse-II, CD80, CD86 und CD40 um den Faktor 2 bis 4. Diese Zellen wiesen zudem immunstimulatorische Eigenschaften in der gemischten (allogenen) Leukozytenkultur auf. Dendritische Zellen der Mauslinie NMRInude exprimierten nach der In-vitro-Kultur ebenfalls zahlreiche Ober¬fl{\"a}chenmarker, darunter die Reifungsmarker. Die St{\"a}rke der Expression war jedoch um bis zu 50 Prozent schw{\"a}cher als bei Dendritischen Zellen der anderen Mauslinien. Dieser Befund weist auf potentielle Unterschiede zwischen Dendritischen Zellen der thymuslosen Mauslinie NMRInude und Dendritischen Zellen von Wildtyp-M{\"a}usen hin. Es wurde gezeigt, dass OptiPrep zur Isolierung Dendritischer Zellen aus M{\"a}usemilzen bei geringem Arbeitsaufwand und niedrigen Kosten verwendet werden kann. Die isolierten Dendritischen Zellen weisen die zu erwartenden ph{\"a}notypischen und funktionellen Eigenschaften auf und scheinen somit f{\"u}r den Einsatz in weiterf{\"u}hrenden Experimenten geeignet.},

  abstract  = {Background: Drug induced immune hemolytic anemia (DIIHA) is a rare complication and often underdiagnosed. DIIHA is frequently associated with a bad outcome, including organ failure and even death. For the last decades, ceftriaxone has been one of the most common drugs causing DIIHA, and ceftriaxone-induced immune hemolytic anemia (IHA) has especially been reported to cause severe complications and fatal outcomes. Case Presentation: A 76-year-old male patient was treated with ceftriaxone for cholangitis. Short time after antibiotic exposure the patient was referred to intensive care unit due to cardiopulmonary instability. Hemolysis was observed on laboratory testing and the patient developed severe renal failure with a need for hemodialysis for 2 weeks. Medical history revealed that the patient had been previously exposed to ceftriaxone less than 3 weeks before with subsequent hemolytic reaction. Further causes for hemolytic anemia were excluded and drug-induced immune hemolytic (DIIHA) anemia to ceftriaxone could be confirmed. Conclusions: The case demonstrates the severity of ceftriaxone-induced immune hemolytic anemia, a rare, but immediately life-threatening condition of a frequently used antibiotic in clinical practice. Early and correct diagnosis of DIIHA is crucial, as immediate withdrawal of the causative drug is essential for the patient prognosis. Thus, awareness for this complication must be raised among treating physicians.},

  abstract  = {We herein report the case of a 73-year-old male patient who was diagnosed with leukemic non-nodal MCL. This patient had received six cycles of bendamustine, which resulted in a transient remission, and a second-line therapy with ibrutinib, which unfortunately failed to induce remission. We started a treatment with single-agent obinutuzumab at a dose of 20 mg on day 1, 50 mg on day 2-4, 330 mg on day 5, and 1000 mg on day 6. The laboratory analysis showed a rapid decrease of leukocyte count. Four weeks later, we repeated the treatment with obinutuzumab at a dose of 1000 mg q4w and started a therapy with venetoclax at a dose of 400 mg qd, which could be increased to 800 mg qd from the third cycle. This combination therapy was well tolerated. The patient achieved a complete remission (CR) after three cycles of obinutuzumab and venetoclax. To date, the patient has a progression-free survival of 17 months under ongoing obinutuzumab maintenance q4w. This is the first report about obinutuzumab and venetoclax induced CR in rituximab-intolerant patient with an ibrutinib-resistant MCL. This case suggests that obinutuzumab- and venetoclax-based combination therapy might be salvage therapy in patients with ibrutinib-resistant MCL.},

  abstract  = {Background Even in the era of novel immunotherapies for multiple myeloma (MM), treatment of late-stage relapsed/refractory (RR) patients remains challenging. The aim of our study was to analyze the efficacy and safety of the five-drug combination pomalidomide, bortezomib, doxorubicin, dexamethasone, and daratumumab ("Pom-PAD-Dara") in RRMM. Methods We retrospectively analyzed data of 56 patients with RRMM who received Pom-PAD-Dara between September 2016 and May 2019. Results Patients were heavily pretreated with a median of four prior lines of therapy, including autologous and allogenic stem cell transplant in 50 (89\%) and six (11\%) patients, respectively. The overall response rate (ORR) was 78\% and we observed partial remission, very good partial remission, and complete remission in 27 (48\%), 13 (23\%) and four (7\%) patients, respectively. Median progression-free survival was 7 months (95\% CI, 3.3-10.7) and the median overall survival was not reached at 24 months. Adverse events grade ≥ 3 were observed 41 (73\%) patients and included neutropenia (n = 28, 50\%), anemia (n = 22, 39\%), thrombocytopenia (n = 21, 38\%), and pneumonia (n = 6, 11\%). Conclusion Pom-PAD-Dara represents a promising multiagent regimen in heavily pretreated RRMM patients with high ORR and an acceptable safety profile.},
