Arrhythmogenic cardiomyopathy is an inherited cardiomyopathy characterized by fibrofatty replacement and a high risk of ventricular arrhythmias and sudden cardiac death. This myocardial disorder is typically transmitted through autosomal dominant pattern and caused by pathogenic variants in the desmosomal and extradesmosomal genes. In this case, we are presenting a family with three members who have arrhythmogenic left ventricular cardiomyopathy. The condition was found to be caused by a nonsense mutation (c.1754 T>G (p. Leu585Ter)) in the desmoplakin (DSP) gene. Unfortunately, two of the family members were initially misdiagnosed and treated for coronary artery disease, which was not the correct diagnosis. This case demonstrates the importance of accurate differential diagnosis and the usefulness of magnetic resonance imaging (MRI) in establishing the correct diagnosis of arrhythmogenic cardiomyopathy.

INTRODUCTION: Fabry disease (FD) can be undiagnosed in the context of multiple sclerosis (MS) due to similar clinical and paraclinical features. Our study aimed to determine the prevalence (and the necessity of screening) of FD among patients with possible or definite MS. METHODS: In this prospective monocentric observational study, we included consecutive patients enrolled between May 2017 and May 2019 after the first clinical event suggestive of MS. All patients underwent FD screening using dried blood spots in a stepwise manner combining genetic and enzyme testing. Patients were followed until May 2022. RESULTS: We included 160 patients (73.1% female, mean age 33.9 years). The 2017 revised McDonald's criteria for definite MS were fulfilled by 74 (46.3%) patients at the time of study recruitment and 89 (55.6%) patients after 3-5 years of follow-up. None of the patients had a pathogenic GLA variant, and four (2.5%) had a variant of unknown significance (p.A143T, p.S126G, 2 × p.D313Y). In two of these patients, the intrathecal synthesis of oligoclonal bands was absent, and none had hyperproteinorachia or pleocytosis in cerebrospinal fluid. Detailed examination of FD organ manifestations revealed only discrete ocular and kidney involvement in two patients. CONCLUSION: The prevalence of FD in the population of suspected or definite MS patients does not appear to be high. Our results do not support routine FD screening in all patients with a possible diagnosis of MS, but there is an urgent need to search for red flags and include FD in the differential diagnosis of MS.

BACKGROUND: Fabry disease (FD) is an X-linked lysosomal storage disease resulting from pathogenic variants in the GLA gene coding α-galactosidase A (AGAL) and cleaving terminal alpha-linked galactose. Globotriaosylceramide (Gb3) is the predominantly accumulated sphingolipid. Gb3, deacylated-Gb3 (lysoGb3), and methylated-Gb3 (metGb3) have been suggested as FD biomarkers. MATERIALS AND METHODS: We developed a novel LC-MS/MS method for assessing lysoGb3 levels in plasma and Gb3 and metGb3 in urine and tested 62 FD patients, 34 patients with GLA variants of unknown significance (VUS) and 59 healthy controls. AGAL activity in white blood cells (WBCs) and plasma was evaluated in parallel. RESULTS: In males, lysoGb3 concentrations in plasma separated classic and late-onset FD patients from each other and from individuals carrying GLA VUS and healthy controls. Calculating AGAL activity/plasmatic lysoGb3 ratio allowed to correctly categorize all females with classic and majority of patients with late-onset FD phenotypes. Correlation of AGAL activity in WBCS with lipid biomarkers identified threshold activity values under which the biomarkers' concentrations increase. CONCLUSION: We developed a novel simplified LC-MS/MS method for quantitation of plasma lysoGb3. AGAL activity/plasma lysoGb3 ratio was identified as the best predictor for FD. AGAL activity correlated with plasma lysoGb3 and corresponded to individual FD phenotypes.

Saphenopopliteal junction classification has been developing, but still the precise knowledge of junction type is crucial for proper surgical treatment. We examined the saphenopopliteal junction by duplex venous scanning in 244 extremities in healthy volunteers (median age: 23.0 years, 83 females, 39 male) and performed a meta-analysis of 13 studies focusing on structural types of the junction. According to Schweighoffer's classification we distinguished 5 types of the junction and we subdivided type A according to Cavezzi's classification of gastrocnemial veins termination into two. We added type F (small saphenous vein-SSV terminates into popliteal vein-PV), described especially in cadaveric studies. In our study, the most frequent type was A1 (96 cases), followed by C (70), B (48), A2 (20), E (6), D (3) and F (0). The pooled prevalence estimate for types A + B + D + E was 54.7% (95% CI 40.9-69.6%) and for type C 24.4% (95% CI 19.3-29.5%), whereas in 17.1% (95% CI 6.3-27.9%) of cases, the SSV terminated in the PV with no cranial extension present. The knowledge of the saphenopopliteal junction and its variations prevalence can help clinicians to quickly identify the real type of the junction during routine examination. In mid-European population, the main type is A1 and worldwide type A.

BACKGROUND: Anderson-Fabry disease (AFD) is an X-linked inherited lysosomal disease caused by a defect in the gene encoding lysosomal enzyme α-galactosidase A (GLA). Atrio-ventricular (AV) nodal conduction defects and sinus node dysfunction are common complications of the disease. It is not fully elucidated how frequently AFD is responsible for acquired AV block or sinus node dysfunction and if some AFD patients could manifest primarily with spontaneous bradycardia in general population. The purpose of study was to evaluate the prevalence of AFD in male patients with implanted permanent pacemaker (PM). METHODS: The prospective multicentric screening in consecutive male patients between 35 and 65 years with implanted PM for acquired third- or second- degree type 2 AV block or symptomatic second- degree type 1 AV block or sinus node dysfunction was performed. RESULTS: A total of 484 patients (mean age 54 ± 12 years at time of PM implantation) were enrolled to the screening in 12 local sites in Czech Republic. Out of all patients, negative result was found in 481 (99%) subjects. In 3 cases, a GLA variant was found, classified as benign: p.Asp313Tyr, p.D313Y). Pathogenic GLA variants (classical or non-classical form) or variants of unclear significance were not detected. CONCLUSION: The prevalence of pathogenic variants causing AFD in a general population sample with implanted permanent PM for AV conduction defects or sinus node dysfunction seems to be low. Our findings do not advocate a routine screening for AFD in all adult males with clinically significant bradycardia.

BACKGROUND: Pegunigalsidase alfa is a novel, PEGylated α-galactosidase-A enzyme-replacement therapy approved in the EU and US to treat patients with Fabry disease (FD). OBJECTIVE/METHODS: BRIDGE is a phase 3 open-label, switch-over study designed to assess safety and efficacy of 12 months of pegunigalsidase alfa (1 mg/kg every 2 weeks) treatment in adults with FD who had been previously treated with agalsidase alfa (0.2 mg/kg every 2 weeks) for ≥ 2 years. RESULTS: Twenty-seven patients were screened; 22 met eligibility criteria; and 20 (13 men, 7 women) completed the study. Pegunigalsidase alfa was well-tolerated, with 97% of treatment-emergent adverse events (TEAEs) being of mild or moderate severity. The incidence of treatment-related TEAEs was low, with 2 (9%) discontinuations due to TEAEs. Five patients (23%) reported infusion-related reactions. Overall mean (SD; n = 22) baseline estimated glomerular filtration rate (eGFR) was 82.5 (23.4) mL/min/1.73 m2 and plasma lyso-Gb3 level was 38.3 (41.2) nmol/L (men: 49.7 [45.8] nmol/L; women: 13.8 [6.1] nmol/L). Before switching to pegunigalsidase alfa, mean (standard error [SE]) annualized eGFR slope was - 5.90 (1.34) mL/min/1.73 m2/year; 12 months post-switch, the mean eGFR slope was - 1.19 (1.77) mL/min/1.73 m2/year; and mean plasma lyso-Gb3 reduced by 31%. Seven (35%) out of 20 patients were positive for pegunigalsidase alfa antidrug antibodies (ADAs) at ≥ 1 study timepoint, two of whom had pre-existing ADAs at baseline. Mean (SE) changes in eGFR slope for ADA-positive and ADA-negative patients were + 5.47 (3.03) and + 4.29 (3.15) mL/min/1.73 m2/year, respectively, suggesting no negative impact of anti-pegunigalsidase alfa ADAs on eGFR slope. CONCLUSION: Pegunigalsidase alfa may offer a safe and effective treatment option for patients with FD, including those previously treated with agalsidase alfa. TRN: NCT03018730. Date of registration: January 2017.

OBJECTIVES: Fabry disease (FD) is a rare X-linked lysosomal storage disorder with variable phenotypes, including neurological symptoms. These can be influenced by vascular impairment. Extracranial and transcranial vascular sonography is an effective and noninvasive method for measuring arterial structures and blood flow. The study aims to investigate cerebrovascular phenotype characteristics in FD patients compared to controls using neurosonology. METHODS: This is a single-center, cross-sectional study of 130 subjects-65 patients (38 females), with genetically confirmed FD, and 65 sex- and age-matched controls. Using ultrasonography, we measured structural and hemodynamic parameters, including distal common carotid artery intima-media thickness, inner vertebral artery diameter, resting blood flow velocity, pulsatility index, and cerebral vasoreactivity (CVR) in the middle cerebral artery. To assess differences between FD and controls and to identify factors influencing investigated outcomes, unadjusted and adjusted regression analyses were performed. RESULTS: In comparison to sex- and age-matched controls, FD patients displayed significantly increased carotid artery intima-media thickness (observed FD 0.69 ± 0.13 mm versus controls 0.63 ± 0.12 mm; Padj = .0014), vertebral artery diameter (observed FD 3.59 ± 0.35 mm versus controls 3.38 ± 0.33 mm; Padj = .0002), middle cerebral artery pulsatility index (observed FD 0.98 ± 0.19 versus controls 0.87 ± 0.11; Padj < .0001), and significantly decreased CVR (observed FD 1.21 ± 0.49 versus controls 1.35 ± 0.38; Padj = .0409), when adjusted by age, BMI, and sex. Additionally, FD patients had significantly more variable CVR (0.48 ± 0.25 versus 0.21 ± 0.14; Padj < .0001). CONCLUSIONS: Our results suggest the presence of multiple vascular abnormalities and changes in hemodynamic parameters of cerebral arteries in patients with FD.

Infekční pseudoaneurysma aorty je rychle progredující onemocnění s vysokou mortalitou, pro něž je zásadní časná diagnostika a kombinovaná terapie. Symptomy jsou kombinací příznaků aortálního syndromu s elevací zánětlivých markerů. Základem terapie je několikatýdenní antibiotická terapie (ideálně cílená dle pozitivity hemokultur) v kombinaci s chirurgickou či endovaskulární terapií dle celkového stavu pacienta. Komplikací je ruptura pseudoaneurysmatu s fatálními následky, která je v závislosti na rychlosti progrese růstu pseudoaneurysmatu značným rizikem.
Infectious pseudoaneurysm of the aorta is a rapidly progressive disease with high mortality. Therefore, early diagnosis and combination therapy are crucial. The condition is manifested by signs of aortic syndrome and elevated inflammatory markers. The treatment consists of antibiotic therapy (based on blood cultures) in combination with surgical or endovascular approach according to the general condition of the patient. The main complication, depending on the rate of progression, is aortic wall rupture with fatal consequences.
