BackgroundLight-chain (AL) cardiac amyloidosis (CA) is characterized by fibril deposits, which are composed of monoclonal immunoglobulin light chains. The right ventricle is mostly involved in AL-CA and impairment of its function is a predictor of worse prognosis.ObjectivesTo characterize the volumetric and functional properties of the right atrium (RA) in AL-CA by three-dimensional speckle-tracking echocardiography (3DSTE).MethodsA total of 16 patients (mean age: 64.5 ± 10.1 years, 11 males) with AL-CA were examined. Their results were compared to that of 15 age- and gender-matched healthy controls (mean age: 58.9 ± 6.9 years, 8 males). All cases have undergone complete two-dimensional Doppler and 3DSTE. A two-tailed p value of less than 0.05 was considered statistically significant.ResultsSignificant differences could be demonstrated in RA volumes respecting cardiac cycle. Total (19.2 ± 9.3% vs. 27.9 ± 10.7%, p = 0.02) and active atrial emptying fractions (12.1 ± 8.1 vs. 18.6 ± 9.8%, p = 0.05) were significantly decreased in AL-CA patients. Peak global (16.7 ± 10.3% vs. 31.2 ± 19.4%, p = 0.01) and mean segmental (24.3 ± 11.1% vs. 38.6 ± 17.6%, p =0.01) RA area strains, together with some circumferential, longitudinal and segmental area strain parameters, proved to be reduced in patients with AL-CA. Global longitudinal (4.0 ± 5.2% vs. 8.2 ± 5.5%, p = 0.02) and area (7.8 ± 8.1% vs. 15.9 ± 10.3%, p = 0.03) strains at atrial contraction and some circumferential and area strain parameters at atrial contraction were reduced in AL-CA patients.ConclusionSignificantly increased RA volumes and deteriorated RA functions could be demonstrated in AL-CA.

Up to 30% of patients with classical Hodgkin lymphoma (cHL) are not responsive to frontline therapy or relapse after primary treatment. In these cases, autologous hematopoietic stem cell transplantation (AHSCT) is the standard of care. The combination of brentuximab vedotin and bendamustine (BV + B) is an effective salvage regimen in this challenging subpopulation. This nationwide multicenter study investigated the real-world efficacy and safety of the BV + B regimen as a bridge to AHSCT in patients with primary refractory or relapsed cHL. A total of 41 cHL patients underwent AHSCT after receiving at least 1 cycle of BV + B (with brentuximab vedotin given at 1.8 mg/kg on day 1 and bendamustine at 90 mg/m2 on days 1–2 every 4 weeks). After a median of 3 (1–6) cycles of BV + B, the objective response rate was 78%, with 29 (70.7%) patients achieving complete remission. Twelve (29.3%) patients relapsed after AHSCT, 2 (4.9%) of them died, while 2 (4.9%) patients are lost to follow-up. After a median of 17 months of follow-up, the estimated 2-year overall- and progression-free survival after AHSCT was 93 and 62%, respectively. Features of advanced disease at recurrence (p = 0.038) and the presence of stage IV cHL at relapse (p = 0.024) are strong predictor markers of unfavorable outcomes. Twenty-four (58.5%) patients experienced adverse events of any grade, while no grade IV toxicities were reported. BV + B is an effective salvage option with a manageable toxicity profile in cHL. The real-world safety and efficacy of this combination are similar to the observations made on the study population.

Bevezetés: A hypereosinophilia-szindróma (HES) és az immunglobulinkönnyűlánc-amyloidosis (ALA) két ritka hematológiai betegség, melyek cardialis eltérésekkel járnak együtt. Célkitűzés: A jelen vizsgálat célja a HES-és ALA-betegek bal kamrai (BK-i) deformációs paramétereinek összehasonlító vizsgálata volt háromdimenziós speckle-tracking echokardiográfia (3DSTE) segítségével. Módszer: A vizsgálatok során 10 HES-beteg (átlagos életkor: 60,9 ± 14,7 év) és 19 ALA-ban szenvedő páciens (átlagos életkor: 63,4 ± 7,8 év, 13 férfi) eredményeit elemeztük. Kontrollcsoportként 13, korban és nemben egyeztetett, egészséges felnőtt szolgált (átlagos életkor: 59,2 ± 4,3 év, 5 férfi). Valamennyi esetben teljes körű kétdimenziós Doppler-echokardiográfiás vizsgálat készült 3DSTE-vel kiegészítve.Eredmények: A kontrollcsoporthoz képest az ALA-betegcsoportban mért valamennyi basalis szegmentális BK-i strain szignifikánsan alacsonyabbnak mutatkozott. Az ALA-betegek globális és átlagolt szegmentális BK-i longitudinális strain (LS) értékei az egészséges kontrollcsoporthoz hasonlítva szignifikánsan alacsonyabbnak bizonyultak. A HESbetegcsoport és az egészséges kontrollok összehasonlítása során szignifikáns különbséget tapasztaltunk a globális BK-LS tekintetében, míg a szegmentális basalis BK-LS is szignifikánsan alacsonyabbnak bizonyult a HES-betegekben. A HES-és az ALA-betegcsoport értékeit összehasonlítva a basalis BK-i radiális és 3D strain mutatott szignifikáns eltérést.Következtetések: A 3DSTE alkalmas módszer a HES-és az ALA-betegcsoportban a BK-i deformációs mechanika részletes vizsgálatára. Mindkét betegcsoportban jelentős deformációs eltérések tapasztalhatók, ALA fennállása esetén az eltérések kifejezettebbek. Orv Hetil. 2020; 161(5): 169-176. Left ventricular deformation in cardiac light-chain amyloidosis and hypereosinophilic syndrome Results from the MAGYAR-Path StudyIntroduction: Hypereosinophilic syndrome (HES) and immunoglobulin light-chain amyloidosis (ALA) are two, rare haematological disorders associated with cardiac alterations. Aim: The goal of the present study was a comparative assessment of left ventricular (LV) deformational parameters in HES and ALA patients using three-dimensional speckle-tracking echocardiography (3DSTE).

The control group contained 13 age-and gender-matched healthy adults (mean age: 59.2 ± 4.3 years, 5 males). All patients underwent a complete two-dimensional Doppler echocardiography followed by 3DSTE. Results: All basal segmental LV strains were significantly reduced in ALA patients as compared to the control group. Global and mean segmental LV longitudinal strain (LS) values of ALA patients proved to be significantly decreased as compared to those of the healthy control group. During comparison of HES patient...
