Introduction: Hypereosinophilic syndrome (HES) is a very heterogeneous group ofdisorders with varied etiologies characterized by peripheral eosinophilia and eosinophilic tissue/end-organ damage. Three-dimensional speckle-tracking echocardiography (3DSTE) was used for assessment of left ventricular (LV) rotational mechanics in HES patients. Methods:The study comprised 13 HES patients, from which one patient was excluded due to insufficient image quality. The remaining patient population consisted of 12 HES cases (mean age: 59.7 ± 13.7 years, eight males). The control group consisted of 36 healthy volunteers (mean age: 52.9 ± 8.3 years, 23 males). 3DSTE was used for the evaluation of LV rotational abnormalities.Results: Both LV apical rotation (4.86 ± 1.92 degree vs 10.07 ± 3.92 degree, P < .0001) and LV twist (8.52 ± 2.79 degree vs 14.41 ± 4.26 degree, P < .0001) showed significant deteriorations in most of HES patients. Time-to-peak LV apical rotation (380 ± 115 ms vs 344 ± 69 ms, P = .56), LV basal rotation (335 ± 148 ms vs 337 ± 111 ms, P = .89), and LV twist (348 ± 91 ms vs 320 ± 60 ms, P = .64) were not significantly different between HES patients and controls. No correlations could be detected between absolute eosinophil count and eosinophil ratio and apical LV rotation (r = 0.12, P = .51 and r = 0.23, P = .45, respectively) and LV twist (r = 0.24, P = .39 and r = 0.31, P = .34, respectively). In two subjects, the absence of LV twist called LV "rigid body rotation" (RBR) was detected. Conclusions: Reduced LV apical rotation and twist could be demonstrated in HES.LV-RBR could be detected in some HES patients.

Increased LA volumes can be demonstrated in HES patients, accompanied by reduced LA peak circumferential strain as assessed by 3DSTE, suggesting LA remodeling.

Increased cyclic right atrial volumes and mild alterations in right atrial functional properties could be demonstrated in idiopathic hypereosinophilic syndrome patients.

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...

Background: Persistent eosinophilia and eosinophil-mediated single-or multiple-organ damage are typical features of hypereosinophilic syndrome (HES). Theoretically, eosinophilic infiltration of the ascending aortic wall could not be excluded in HES, therefore the present study aimed to test whether HES is associated with abnormalities in aortic elastic properties.Methods: The present study comprised 10 HES patients (mean age: 57.6±10.1 years, 5 males) without

Our case is a rare example of the extraordinary tumor-mimicking colon amyloidosis that led to the diagnosis of multiple myeloma. Beside haematological treatment, strict follow-up of the colon process and reconsideration of surgical therapy or endoscopic stenting is of great importance.

BackgroundVaccination has proven the potential to control the COVID-19 pandemic worldwide. Although recent evidence suggests a poor humoral response against SARS-CoV-2 in vaccinated hematological disease (HD) patients, data on vaccination in these patients is limited with the comparison of mRNA-based, vector-based or inactivated virus-based vaccines.MethodsForty-nine HD patients and 46 healthy controls (HCs) were enrolled who received two-doses complete vaccination with BNT162b2, or AZD1222, or BBIBP-CorV, respectively. The antibodies reactive to the receptor binding domain of spike protein of SARS-CoV-2 were assayed by Siemens ADVIA Centaur assay. The reactive cellular immunity was assayed by flow cytometry. The PBMCs were reactivated with SARS-CoV-2 antigens and the production of activation-induced markers (TNF-α, IFN-γ, CD40L) was measured in CD4+ or CD8+ T-cells ex vivo.ResultsThe anti-RBD IgG level was the highest upon BNT162b2 vaccination in HDs (1264 BAU/mL) vs. HCs (1325 BAU/mL) among the studied groups. The BBIBP-CorV vaccination in HDs (339.8 BAU/mL ***p &lt; 0.001) and AZD1222 in HDs (669.9 BAU/mL *p &lt; 0.05) resulted in weaker antibody response vs. BNT162b2 in HCs. The response rate of IgG production of HC vs. HD patients above the diagnostic cut-off value was 100% vs. 72% for the mRNA-based BNT162b2 vaccine; 93% vs. 56% for the vector-based AZD1222, or 69% vs. 33% for the inactivated vaccine BBIBP-CorV, respectively. Cases that underwent the anti-CD20 therapy resulted in significantly weaker (**p &lt; 0.01) anti-RBD IgG level (302 BAU/mL) than without CD20 blocking in the HD group (928 BAU/mL). The response rates of CD4+ TNF-α+, CD4+ IFN-γ+, or CD4+ CD40L+ cases were lower in HDs vs. HCs in all vaccine groups. However, the BBIBP-CorV vaccine resulted the highest CD4+ TNF-α and CD4+ IFN-γ+ T-cell mediated immunity in the HD group.ConclusionWe have demonstrated a significant weaker overall response to vaccines in the immunologically impaired HD population vs. HCs regardless of vaccine type. Although, the humoral immune activity against SARS-CoV-2 can be highly evoked by mRNA-based BNT162b2 vaccination compared to vector-based AZD1222 vaccine, or inactivated virus vaccine BBIBP-CorV, whereas the CD4+ T-cell mediated cellular activity was highest in HDs vaccinated with BBIBP-CorV.
