[PMID: 38668795 PMCID: PMC11192814 DOI: 10.1007/s00431-024-05570-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 04/07/2024] [Accepted: 04/13/2024] [Indexed: 06/22/2024]
Abstract
Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease characterized by recurring serosal inflammation. Cardiac involvement in FMF commonly manifests as pericarditis and pericardial effusion; however, there is limited research on myocardial function. This study aimed to assess cardiac functions during active inflammation and remission periods of FMF patients and investigate the cardiac effects of inflammation during the attack period. Thirty-eight FMF patients without additional cardiac diseases were included in the study. Demographic characteristics, clinical symptoms, family history, and MEFV gene analysis results were obtained retrospectively. Blood tests, blood pressure measurements, electrocardiogram evaluations, conventional echocardiography, and speckle tracking echocardiography were performed during the attack and remission periods. Disease severity was assessed using the Pras scoring system. During the attack period, FMF patients exhibited significantly higher leukocyte count, neutrophil count, C-reactive protein, and erythrocyte sedimentation rate compared to the remission period (p < 0.005). Speckle tracking echocardiography revealed decreased function in the inferior segments of the left ventricle during the attack period (p < 0.005). Right ventricular function was more affected in the moderate disease group. FMF patients with lymphopenia during the attack demonstrated more impaired right ventricular function compared to those with normal lymphocyte count. Conclusions: FMF patients experience cardiac abnormalities during active inflammation, highlighting the importance of monitoring cardiac functions in these patients. Speckle tracking echocardiography can provide valuable insights into cardiac involvement in FMF. These findings emphasize the cardiac impact of FMF inflammation and the significance of long-term cardiac function monitoring in the management of FMF patients. What is Known: • The current literature lacks studies investigating myocardial function in the pediatric population during the attack period of this particular disease. • Our objective was to assess the alterations in cardiac function during the attack and remission periods, considering clinical manifestations, disease severity, acute phase reactant levels, and mutation type. We also evaluated the pattern of cardiac involvement and the affected cardiac areas by comparing remission and attack periods. What is New: • Several studies have demonstrated a rise in the prevalence of ischemic cardiac disease and mortality among individuals with FMF. • Investigating cardiac involvement during the attack period in FMF patients can provide valuable insights for the prevention of long-term complications.

Abstract
OBJECTIVES Familial Mediterranean fever is an autosomal recessive autoinflammatory inherited disease. We aimed to evaluate cardiac involvement in children with familial Mediterranean fever during the attack-free period. MATERIAL AND METHODS The prospective study included 75 familial Mediterranean fever patients during the attack-free period and 50 healthy children. Cardiac evaluation was performed using electrocardiography, 24-hour ambulatory Holter monitoring, and conventional and tissue Doppler echocardiography. Aortic stiffness indices were calculated. RESULTS There were no differences between the groups in age, height, sex, body mass index, and arterial blood pressure parameters (p > 0.05). QT and corrected QT dispersion parameters were similar in both groups (p > 0.05). The E wave velocity and the E/A ratio of the mitral and tricuspid valves decreased, and the A wave velocity of the tricuspid and mitral valve increased in familial Mediterranean fever by the Doppler echocardiography (p < 0.05). The myocardial contraction velocities (Sd), early relaxation velocity (Ed), and Ed/late relaxation velocity (Ad) of both ventricles were decreased in familial Mediterranean fever group, whereas the Ad of both ventricles and the interventricular septum was increased in familial Mediterranean fever group. Aortic strain and distensibility were decreased, and pressure strain elastic modules (Ep), pressure strain normalised (Ep*) by diastolic pressure, and aortic stiffness β index were increased in familial Mediterranean fever patients (p < 0.05). When time domain heart rate variability parameters were evaluated, SDNN-i, RMSSD, and PNN50 significantly decreased in familial Mediterranean fever patients (p < 0.05), whereas SDNN and SDANN were similar in both groups (p > 0.05). CONCLUSION Our findings showed that cardiac involvement could exist in familial Mediterranean fever patients, even during nonattack periods.

Abstract
Aim: Familial Mediterranean fever is an autoinflammatory disease characterized by attacks of inflammation. Despite treatment, there is evidence of subclinical persistence of inflammation with normal laboratory values. This study was conducted to investigate the cardiac effects of continued subclinical inflammation in children and the predisposition towards arrhythmia in familial Mediterranean fever.
Materials and Methods: Age and sex-matched familial Mediterranean fever patients and healthy controls were compared in terms of demographic, laboratory, echocardiographic and electrocardiographic data. The patients with familial Mediterranean fever were grouped according to disease severity scores and compared in terms of electrocardiographic data that could indicate arrhythmogenesis. Correlation analysis was used to examine the relationship between the electrocardiographic measurements and the clinical and laboratory data.
Results: In the comparison of the two groups, no significant difference was found in the echocardiographic measurements in terms of left ventricular systolic and diastolic functions. According to these data, QT and Tp-e intervals were significantly longer in those with familial Mediterranean fever (p=0.002, p=0.046, respectively). When the patients were classified according to the 3 separate disease severity scores, QT dispersion in the moderate-severe disease group was significantly longer than in the mild disease group (p

Whole-Exome Sequencing Revealed New Candidate Genes for Human Dilated Cardiomyopathy. Diagnostics (Basel) 2022; 12:diagnostics12102411.

Abstract
Dilated cardiomyopathy (DCM) is a complex disease affecting young adults. It is a pathological condition impairing myocardium activity that leads to heart failure and, in the most severe cases, transplantation, which is currently the only possible therapy for the disease. DCM can be attributed to many genetic determinants interacting with environmental factors, resulting in a highly variable phenotype. Due to this complexity, the early identification of causative gene mutations is an important goal to provide a genetic diagnosis, implement pre-symptomatic interventions, and predict prognosis. The advent of next-generation sequencing (NGS) has opened a new path for mutation screening, and exome sequencing provides a promising approach for identifying causal variants in known genes and novel disease-associated candidates. We analyzed the whole-exome sequencing (WES) of 15 patients affected by DCM without overloading (hypertension, valvular, or congenital heart disease) or chronic ischemic conditions. We identified 70 pathogenic or likely pathogenic variants and 1240 variants of uncertain clinical significance. Gene ontology enrichment analysis was performed to assess the potential connections between affected genes and biological or molecular function, identifying genes directly related to extracellular matrix organization, transcellular movement through the solute carrier and ATP-binding cassette transporter, and vitamin B12 metabolism. We found variants in genes implicated to a different extent in cardiac function that may represent new players in the complex genetic scenario of DCM.

Abstract
BACKGROUND Familial Mediterranean fever (FMF) is an autoinflammatory disease that can have conduction disturbances and cardiac rhythm disorders as manifestations of cardiac involvement. The aim of the study is to assess the susceptibility of children with FMF to cardiac repolarization abnormalities and therefore arrhythmia in children with FMF. METHODS A cross sectional study conducted on 60 children had FMF and 40 age and sex matched healthy controls. Cardiac repolarization markers, cardiac dimensions and functions were assessed by electrocardiogram (ECG) and conventional echocardiography in patients and controls. RESULTS The mean ± SD age of the patients was 10.43 ± 3.472 years, corrected QT (QTc) and the ratio of peak to end T wave (Tpe) over QTc interval (Tpe /QTc) increased significantly in FMF patients more than healthy control (p value 0.023 and 0.022 respectively). P wave dispersion (Pd) was significantly higher in FMF patients with amyloidosis (p value 0.030). No significant difference was found in cardiac dimensions and functions between the two groups. We found a statistically negative correlation between Pd and age of patients at time of study, age of disease onset and age at diagnosis. On the other hand, we found a statistically significant positive correlation between Pd with number of attacks per year and disease severity score. Furthermore, Tpe/QTc ratio correlated with FMF 50 score, QTc correlated with 24 hours proteinuria. QT, JT intervals correlated with fibrinogen. CONCLUSIONS FMF Patients may have increased risk of arrhythmia and should be monitored on regular basis. Compliance to colchicine therapy and better disease control might play a role in decreasing this risk.

Abstract
Familial Mediterranean fever (FMF) is a systemic autoinflammatory disorder characterized by recurrent attacks of fever and serous inflammation. The association between FMF and risk of cardiac arrhythmia is continuously questioned; some studies report abnormal cardiac repolarization, while others do not. Considering this controversy, we aim to perform in a large cohort of FMF patients a total cosine R to T (TCRT) analysis, a previously unexplored repolarization marker in this disorder. METHODS The study group included 56 FMF patients without amyloidosis, diagnosed with FMF according to published criteria and 131 control subjects, unaffected with FMF. A 12-lead electrocardiogram (ECG) was performed according to strict standards. Electrocardiogram files were processed with Python-based computer software. Patients were followed for 10 to 12 years, and the rate of cardiac complications was evaluated. RESULTS Other than FMF and prescription of colchicine, both groups had similar medical and demographic background. TCRT results were similar for a randomly selected beat (0.40 ± 0.06 vs 0.50 ± 0.04, p > 0.05) and for an averaged beat (0.39 ± 0.06 vs 0.50 ± 0.04, p > 0.05) in FMF patients and control subjects, respectively. Correction of average TCRT for heart rate also resulted in similar TCRTc values in patients and control groups (0.42 ± 0.07 s vs 0.51 ± 0.05 s, respectively, p > 0.05). During the follow-up period, none of the patients died, and no patient developed clinical symptoms suggestive of ventricular arrhythmias. CONCLUSIONS Colchicine treated uncomplicated FMF patients have normal TCRT and TCRTc values, implying low risk for cardiac arrhythmias in this population. Future studies should evaluate the sensitivity and specificity of this marker in high-risk FMF populations, such as those who developed AA amyloidosis.

Abstract
Familial Mediterranean fever is a chronic inflammatory disease characterized by periodic and self-limited episodes of fever and aseptic polyserositis. Although colchicine treatment has altered the course of the disease, it is believed that subclinical inflammation is still present, leading to endothelial dysfunction and atherosclerosis in the course of time. In this review, following the published recommendations, we queried online databases such as MEDLINE Pubmed, Scopus, and Web of science for peer-reviewed studies and reviews written in English language, using the following keywords: familial Mediterranean fever, children, endothelial dysfunction, atherosclerosis, cardiovascular disease. The objective of this review is to highlight the correlation between familial Mediterranean fever and atherosclerosis, and moreover to describe new serum inflammatory markers and non-invasive methods of endothelial dysfunction, to detect the atherosclerosis process early starting from childhood.

Abstract
Familial Mediterranean fever (FMF) is the most common inherited autoinflammatory disease in the world. The long-term effects of subclinical inflammation in FMF are not well recognized. Some studies have suggested that FMF is associated with cardiac autonomic dysfunction in adult FMF patients. The objective of this study was to investigate the cardiac autonomic functions in pediatric FMF patients by using several autonomic tests. Thirty-five patients with FMF and 35 healthy controls were enrolled in this cross-sectional study. Demographic data, disease-specific data, and orthostatic symptoms were recorded. In all participants, 12-lead electrocardiography (ECG), 24 h ambulatory electrocardiographic monitoring, transthoracic echocardiography, treadmill exercise test, and head upright tilt-table (HUTT) test were performed. The heart rate recovery (HRR) indices of the two groups were similar. Also, chronotropic response was similar in both groups. The time-domain parameters of heart rate variability (HRV) were similar in both groups, except mean RR (p = 0.024). Frequencies of ventricular and supraventricular ectopic stimuli were similar in both groups. There were no statistically significant differences between the groups in average QT and average corrected QT interval length, average QT interval dispersion, and average QT corrected dispersion. There was no significant difference between the two groups regarding the ratio of clinical dysautonomic reactions on HUTT. However, we observed a significantly higher rate of dysautonomic reactions on HUTT in patients with exertional leg pain than that in patients without (p = 0.013). When the fractal dimension of time curves were compared, FMF patients exhibited significantly lower diastolic blood pressure parameters than controls in response to HUTT. Cardiovascular autonomic dysfunction in children with FMF is not prominent. Particularly, patients with exertional leg pain are more prone to have dysautonomic features. Further studies are needed to elucidate the exact mechanisms leading to impaired cardiac autonomic functions in FMF.

Abstract
INTRODUCTION Colchicine has been successfully used for the treatment of neutrophilic disorders such as familial Mediterranean fever (FMF), Behçet disease (BD) and gout. There is a growing interest in its cardiovascular effects. AREAS COVERED A MEDLINE/PubMed search for English articles published from January 1972 to June 2015 was completed using the following terms: therapy, pharmacokinetics, efficiency, side effects, toxicity, heart, colchicine, inflammation, FMF, amyloidosis, BD, gout, cardiovascular disorders, pericarditis, arrhythmias, inflammation, neutrophils, platelets. EXPERT OPINION By targeting neutrophils, endothelial cells and platelets, inhibiting mitosis, vascular hyperplasia and fibrosis, colchicine improves outcomes of pericarditis, myocardial ischemia and coronary interventions. Studies in neutrophilic rheumatic diseases and cardiovascular disorders demonstrated that oral colchicine at doses of 0.5 - 2.5 mg/daily is useful for treating pericarditis, myocardial ischemia and coronary occlusion. In rheumatic and cardiovascular disorders, therapeutic doses of the drug reduce C-reactive protein to levels below 2 mg/L, prevent myocardial damage and preserve normal values of atrial and ventricular impulse generation. One of the drug's frequent side effects is diarrhea, which is treated by diet modification or temporary discontinuation of the therapy. Certain drugs (macrolides, statins), comorbidities and certain genetic factors increase risk of colchicine toxicity.

Abstract
BACKGROUND Familial Mediterranean Fever (FMF) is a hereditary autoinflammatory disease associated with subclinical inflammation, which includes atherosclerosis arising from endothelial inflammation, which in turn increases the risk of atrial or ventricular arrhythmias. Conduction abnormalities can be detected using the electrocardiographic (ECG) indices P and QT dispersion (Pdisp and QTdisp). Currently, it is unknown whether patients with FMF are more likely to have abnormalities of these ECG indices. Moreover, existing studies were conducted in countries with higher FMF prevalence. We therefore perform the first prospective study assessing Pdisp and QTdisp in adult FMF patients in Germany, where prevalence of FMF is low. METHOD Asymptomatic FMF patients (n=30) of Turkish ancestry living in Germany and age-matched healthy controls (n=37) were prospectively assessed using 12-lead ECG. RESULTS Patients and controls were comparable in gender and body mass index, and patients had higher erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and serum amyloid A (SAA) compared to controls (ESR: 23.7±14.3 vs. 16.1±13,3 mm/1(st)h, p=0.03, CRP: 0.73±0.9 vs. 0.26±0.4 g/dl, p=0.01, SAA: 3.14±4,8 vs. 0.37±0.3 mg/dl, p<0.01). No statistically significant difference between patients and controls respectively, for Pdisp (43.7±11.9 vs. 47.1±11.2ms, p=0.23), QTdisp (65.9±12.3 vs. 67.6±12.7 ms, p=0.58) or corrected QTdisp (cQTdisp: 73.9±15.0 vs. 76.0±13.3 ms, p=0.55) was found. No correlation could be found between Pdisp or QTdisp or cQTdisp and any of the biochemical markers of inflammation. CONCLUSION FMF patients living in Germany show a Pdisp and QTdisp comparable to healthy controls, with no increased risk of atrial or ventricular arrhythmias indicated.
