    Abstract: This study integrates analyses of mitochondrial DNA sequences and morphological and acoustic data to re-evaluate the taxonomic status of Rhinolophus rex rex , R. r. paradoxolophus and R. schnitzleri throughout their distribution ranges. Based on a dense geographic sampling of specimens hitherto referred to these taxa and contrary to the current taxonomic view, our results indicate that all examined specimens of these taxa are representatives of a single, widely distributed and morphologically variable species, R. rex . The recognition of its geographic populations as different subspecies ( R. r. rex and R. r. paradoxolophus ) or distinct species ( R. schnitzleri ) based on morphological and acoustic data should be regarded as invalid. In the light of this revision, we also reassess the conservation status of R. rex against IUCN Red List criteria as Near Threatened.

    Abstract: Összefoglaló. Célkitűzés: A monoklonális gammopathia szemészeti jeleinek és szövődményeinek vizsgálata. Betegek és módszerek: Két nagy budapesti hematológiai ellátóhely 1999 és 2020 között diagnosztizált és/vagy kezelt, monoklonális gammopathiát mutató betegeit vizsgáltuk (42 beteg 84 szeme, 42,86% férfi; átlagéletkor 63,83 ± 10,76 év). A hematológiai diagnózis 3 esetben bizonytalan jelentőségű monoklonális gammopathia, 34 esetben myeloma multiplex, 3 esetben parázsló myeloma, 1-1 esetben Waldenström-macroglobulinaemia és amyloidosis voltak. Kontrollcsoportként véletlenszerűen kiválasztott, hasonló korcsoportú, hematológiai betegség nélküli egyéneket vizsgáltunk (43 beteg 86 szeme, 32,56% férfi; átlagéletkor 62,44 ± 11,89 év). A szemészeti vizsgálat előtt minden személy kitöltötte a Szemfelszíni Betegség Index (OSDI-) kérdőívet. A szemészeti vizsgálat során a látóélesség vizsgálata mellett pupillatágítást követően réslámpás vizsgálatot végeztünk. Eredmények: Monoklonális gammopathiában az OSDI-érték szignifikánsan magasabb volt, mint a kontrollokban (p = 0,002). Gammopathiában 3 beteg 5 szeménél (5,95%) találtunk potenciális szaruhártya-immunglobulinlerakódást. Gammopathiában szárazszem-betegség 66,67%-ban, szürke hályog 55,95%-ban, Meibom-mirigy-diszfunkció 20,24%-ban, hátsó kérgi szürke hályog 19,05%-ban, egyéb szaruhártyahegek és -homályok 17,86%-ban, krónikus szemhéjgyulladás 14,29%-ban, szemészeti eltérés hiánya 11,90%-ban, macula- és/vagy retinadrusen 9,52%-ban, szaruhártya-immunglobulinlerakódás 5,95%-ban, epiretinalis membrán 5,95%-ban, korábbi szürkehályog-műtét 5,95%-ban, glaucoma 4,76%-ban, Fuchs-dystrophia 2,38%-ban, perifériás retinadegeneráció 2,38%-ban, chorioidea naevus 2,38%-ban, diabeteses retinopathia 1,19%-ban, arteria centralis retinae elzáródás 1,19%-ban, vena centralis retinae ágelzáródás 1,19%-ban, amblyopia 1,19%-ban volt kimutatható. A szárazszem-betegség (p = 0,002), a hátsó kérgi szürke hályog (p = 0,001), a szürke hályog (p 〈 0,00001) és az egyéb szaruhártyahegek és -homályok (p = 0,01) szignifikánsan magasabb arányban fordultak elő a monoklonális gammopathiát mutató betegekben, mint a kontrollokban. Következtetés : Monoklonális gammopathiában a szárazszem-betegség és a szürke hályog a leggyakoribb szemészeti eltérés. A monoklonális gammopathia potenciális szemészeti jelei és szövődményei miatt javasoljuk a betegek évenkénti szemészeti ellenőrzését, életminőségük javítása érdekében. Orv Hetil. 2021; 162(38): 1533–1540. Summary. Objective: To examine ocular signs and ocular comorbidities in monoclonal gammopathy. Patients and methods: We analyzed patients from two large referral hematology centers in Budapest, who were diagnosed and/or treated with monoclonal gammopathy between 1997 and 2020 (84 eyes of 42 patients, 42.86% male, mean age 63.83 ± 10.76 years). Before the ophthalmic examination, the subjects filled in the Ocular Surface Disease Index (OSDI) questionnaire. Ophthalmic examination included visual acuity test and slit-lamp examination following dilation of the pupil. Results: OSDI scores were significantly higher in subjects with monoclonal gammopathy than in controls (p = 0.002). Among gammopathy subjects, we observed potential corneal immunoglobulin deposition in 5 eyes of 3 patients (5.95%). In gammopathy subjects, there was dry eye disease (66.67%), cataract (55.95%), Meibomian gland dysfunction (20.24%), posterior cortical cataract (19.05%), corneal scars and degenerations (17.86%), chronic blepharitis (14.29%), absence of ocular complaint (11.90%), macular or retinal drusen (9.52%), corneal immunoglobulin deposition (5.95%), epiretinal membrane (5.95%), previous cataract surgery (5.95%), glaucoma (4.76%), Fuchs dystrophy (2.38%), peripheral retinal degeneration (2.38%), chorioideal naevus (2.38%), diabetic retinopathy (1.19%), central retinal artery occlusion (1.19%), central retinal vein branch occlusion (1.19%) and amblyopia (1.19%). The proportion of dry eye disease (p = 0.002), posterior cortical cataract (p = 0.001), cataract (p 〈 0.00001), and corneal scars and degenerations (p = 0.01) were significantly higher in gammopathy subjects than in controls. Conclusion: Dry eye disease and cataracts are the most common ocular comorbidities in patients with monoclonal gammopathy. Therefore, due to the potential ocular signs and comorbidities of monoclonal gammopathy, we suggest a regular, yearly ophthalmic checkup of these patients to improve their quality of life.

    Abstract: Összefoglaló. Célkitűzés: A monoklonális fehérjetermeléssel járó haematológiai kórképek szemészeti tüneteinek és szemészeti társbetegségeinek összefoglalása irodalmi adatok alapján. Módszer: A Pubmed ben rendelkezésre álló adatok kigyűjtése, elemzése és összefoglalása. Eredmények: Immunglobulin-lerakódás a szem szövetei közül leggyakrabban a szaruhártyában figyelhető meg (paraproteinaemiás vagy immuntaktoid keratopathia). A monoklonális fehérjeszaporulattal járó plazmasejtes betegség gyakoribb szemészeti jelei pedig a paraproteinaemiás keratopathia mellett a kristályhordozó histiocytosis (CSH), a hypercupremiás keratopathia, a foveolaris drusen/maculopathia és az orbitalis plasmocytoma. A ritkább szemészeti jelek/tünetek közé az akut/krónikus uveitis, a Doyne retina dystrophia és az arteria vagy vena centralis retinae elzáródása tartoznak. Szemészeti mellékhatás szisztémás szteroidok és a belantamab mafotidin alkalmazásakor jelentkeznek. Következtetések: A monoklonális gammopathiával járó kórképek sokszínű szemészeti panaszokkal jelentkezhetnek a klinikai gyakorlatban, aminek felismerése a megfelelő kivizsgálás elindításával a szemész feladata. A betegek kezelése és gondozása során a haematológusok és szemészek együttműködése a számos ismert szemészeti tünet és társbetegség miatt elengedhetetlen. A megfelelő szemészeti kezeléssel a látóélesség és ezáltal a betegek életminősége jelentősen javítható. Summary. Purpose: To summarize ocular symptoms and ocular comorbidities of monoclonal gammopathy, based on literature data. Methods: A comprehensive Pubmed search has been performed to summarize ocular symptoms and comorbidities before January 2021. Results: Immunglobulin deposition was most commonly observed in the corneal tissue (paraproteinaemic or immuntactoid keratopathy). Beside paraproteinaemic keratopathy, the most common ocular signs and ocular comorbidities of plasma cell disorders with monoclonal gammopathy are crystal-storage histiocytosis (CSH), hypercupremic keratopathy, foveolar drusen/maculopathy and orbital plasmocytoma. Less common ocular signs are acute/chronic uveitis, Doyne retinal dystrophy, central retinal artery or vein occlusion. Ophthalmic side effects are expected following the use of systemic steroids or belantamab mafotidin. Conclusions: Monoclonal gammopathy may present with diverse ocular symptoms in the clinical practice, which should be examined and treated through an ophthalmologist. Therefore, collaboration of haematologists and ophthalmologists is essential for these patients. With appropriate ophthalmic treatment, there is a significant improvement of best corrected visual acuity of these patients, with a significant impact on their quality of life.

    Abstract: Canine morbillivirus (canine distemper virus, CDV) is a member of the Paramyxoviridae family. Canine distemper is a serious viral disease that affects many mammalian species, including members of the Mustelidae family. These animals have an elusive nature, which makes related virological studies extremely challenging. There is a significant knowledge gap about the evolution of their viruses and about the possible effects of these viruses to the population dynamics of the host animals. Spleen and lung tissue samples of 170 road-killed mustelids belonging to six species were collected between 1997 and 2022 throughout Hungary and tested for CDV with real-time RT-PCR. Results Three species were positive for viral RNA, 2 out of 64 Steppe polecats ( Mustela eversmanii ), 1 out of 36 European polecats ( Mustela putorius ) and 2 out of 36 stone martens ( Martes foina ); all 18 pine martens ( Martes martes ), 10 least weasels ( Mustela nivalis ) and 6 stoats ( Mustela erminea ) tested negative. The complete CDV genome was sequenced in five samples using pan-genotype CDV-specific, amplicon-based Nanopore sequencing. Based on the phylogenetic analysis, all five viral sequences were grouped to the Europe/South America 1 lineage and the distribution of one sequence among trees indicated recombination of the Hemagglutinin gene. We verified the recombination with SimPlot analysis. Conclusions This paper provides the first CDV genome sequences from Steppe polecats and additional complete genomes from European polecats and stone martens. The infected specimens of various species originated from distinct parts of the country over a long time, indicating a wide circulation of CDV among mustelids throughout Hungary. Considering the high virulence of CDV and the presence of the virus in these animals, we highlight the importance of conservation efforts for wild mustelids. In addition, we emphasize the importance of full genomic data acquisition and analysis to better understand the evolution of the virus. Since CDV is prone to recombination, specific genomic segment analyses may provide less representative evolutionary traits than using complete genome sequences.

    Abstract: Purpose. To examine the ocular signs of monoclonal gammopathy and to evaluate ocular comorbidities in subjects with monoclonal gammopathy. Patients and Methods. We analyzed patients from two large referral hematology centers in Budapest, diagnosed and/or treated with monoclonal gammopathy between 1997 and 2020. As a control group, randomly selected individuals of the same age group, without hematological disease, have been included. There were 160 eyes of 80 patients (38.75% males; age 67.61 ± 10.48 (range: 38–85) years) with monoclonal gammopathy and 86 eyes of 43 control subjects (32.56% males; age 62.44 ± 11.89 (range 37–86) years). The hematological diagnosis was MGUS in 9 (11.25%), multiple myeloma in 61 (76.25%), smoldering myeloma in 6 (7.50%), and amyloidosis or Waldenström macroglobulinemia in 2 cases (2.50%–2.50%). Before detailed ophthalmic examination with fundoscopy, 42 subjects with gammopathy (52.50%) and all controls filled the Ocular Surface Disease Index (OSDI) questionnaire. Results. The OSDI score and best-corrected visual acuity (BCVA) were significantly worse in subjects with monoclonal gammopathy than in controls ( p = 0.02 ; p = 0.0005 ). Among gammopathy subjects, we observed potential corneal immunoglobulin deposition in 6 eyes of 4 (3.75%) patients. Ocular surface disease ( p = 0.0001 ), posterior cortical cataract ( p = 0.01 ), and cataract ( p = 0.0001 ) were significantly more common among gammopathy subjects than in controls (χ2 test). Conclusions. Ocular surface disease and cataract are more common, and BCVA is worse in patients with monoclonal gammopathy than in age-matched controls. Therefore, and due to the potential ocular signs and comorbidities of monoclonal gammopathy, we suggest a regular, yearly ophthalmic checkup of these patients to improve their quality of life.

    Abstract: In the past ten years, several novel hantaviruses were discovered in shrews, moles, and bats, suggesting the dispersal of hantaviruses in many animal taxa other than rodents during their evolution. Interestingly, the coevolutionary analyses of most recent studies have raised the possibility that nonrodents may have served as the primordial mammalian host and harboured the ancestors of rodent-borne hantaviruses as well. The aim of our study was to investigate the presence of hantaviruses in bat lung tissue homogenates originally collected for taxonomic purposes in Malaysia in 2015. Hantavirus-specific nested RT-PCR screening of 116 samples targeting the L segment of the virus has revealed the positivity of two lung tissue homogenates originating from two individuals, a female and a male of the Murina aenea bat species collected at the same site and sampling occasion. Nanopore sequencing of hantavirus positive samples resulted in partial genomic data from S, M, and L genome segments. The obtained results indicate molecular evidence for hantaviruses in the M. aenea bat species. Sequence analysis of the PCR amplicon and partial genome segments suggests that the identified virus may represent a novel species in the Mobatvirus genus within the Hantaviridae family. Our results provide additional genomic data to help extend our knowledge about the evolution of these viruses.

    Abstract: Background: Monoclonal gammopathy (MG) is characterized by monoclonal protein overproduction, potentially leading to the development of hyperviscosity syndrome. Objective: To assess retinal circulation using optical coherence tomography angiography (OCTA) parameters in patients with monoclonal gammopathy. Methods: OCTA measurements were performed using the Optovue AngioVue system by examining 44 eyes of 27 patients with MG and 62 eyes of 36 control subjects. Superficial and deep retinal capillary vessel density (VD SVP and DVP) in the whole 3 × 3 mm macular and parafoveal area, foveal avascular zone (FAZ) area, and central retinal thickness (CRT) were measured using the AngioAnalytics software. The OCTA parameters were evaluated in both groups using a multivariate regression model, after controlling for the effect of imaging quality (SQ). Results: There was no significant difference in age between the subjects with monoclonal gammopathy and the controls (63.59 ± 9.33 vs. 58.01 ± 11.46 years; p 〉 0.05). Taking into account the effect of image quality, the VD SVP was significantly lower in the MG group compared to the control group (44.54 ± 3.22% vs. 46.62 ± 2.84%; p 〈 0.05). No significant differences were found between the two groups regarding the other OCTA parameters (p 〉 0.05). Conclusions: A decreased superficial retinal capillary vessel density measured using OCTA in patients with MG suggests a slow blood flow, reduced capillary circulation, and consequent tissue hypoperfusion. An evaluation of retinal circulation using OCTA in cases of monoclonal gammopathy may be a sensitive method for the non-invasive detection and follow-up of early microcirculatory dysfunction caused by increased viscosity.

    Abstract: Background: Corneal imaging may support an early diagnosis of monoclonal gammopathy. The goal of our study was to analyze corneal stromal properties using Pentacam and in vivo confocal cornea microscopy (IVCM) in subjects with monoclonal gammopathy. Patients and methods: In our cross-sectional study, patients with monoclonal gammopathy (130 eyes of 65 patients (40.0% males; age 67.65 ± 9.74 years)) and randomly selected individuals of the same age group, without hematological disease (100 eyes of 50 control subjects (40.0% males; age 60.67 ± 15.06 years)) were included. Using Pentacam (Pentacam HR; Oculus GmbH, Wetzlar, Germany), corneal stromal light scattering values were obtained (1) centrally 0–2 mm zone; (2) 2–6 mm zone; (3) 6–10 mm zone; (4) 10–12 mm zone. Using IVCM with Heidelberg Retina Tomograph with Rostock Cornea Module (Heidelberg Engineering, Heidelberg, Germany), the density of hyperreflective keratocytes and the number of hyperreflective spikes per image were manually analyzed, in the stroma. Results: In the first, second and third annular zone, light scattering was significantly higher in subjects with monoclonal gammopathy, than in controls (p ≤ 0.04). The number of hyperreflective keratocytes and hyperreflective spikes per image was significantly higher in stroma of subjects with monoclonal gammopathy (p ≤ 0.012). Conclusions: Our study confirms that increased corneal light scattering in the central 10 mm annular zone and increased keratocyte hyperreflectivity may give rise to suspicion of monoclonal gammopathy. As corneal light scattering is not increased at the limbal 10–12 mm annular zone in monoclonal gammopathy subjects, our spatial analysis provides evidence against the limbal origin of corneal paraprotein deposition. Using IVCM, stromal hyperreflective spikes may represent specific signs of monoclonal gammopathy.
