ABSTRACT

Background: 22q11.2 deletion syndrome (22q11.2DS) is a microdeletion syndrome exhibiting significant clinical phenotype variability. This study aimed to investigate the clinical features, immune profiles, and cognitive abilities of 22q11.2DS patients receiving treatment at MacKay Memorial Hospital in Taipei, Taiwan. Methods: This is a cross-sectional analysis between January 2001 and December 2022. We recruited 27 patients with 22q11.2DS using fluorescence in situ hybridization (FISH), multiplex ligation-dependent probe amplification (MLPA) and array comparative genomic hybridization (aCGH). Our evaluation included patient history, physical examination, laboratory analysis, and cardiac and cognitive assessment. Results: We included 27 patients with 22q11.2DS, 7 (25.9%) of whom were female. The median age of the patients was 17.9 yr. Ninety-three percent of the patients exhibited the characteristic facial features associated with the syndrome. A family history of 22q11.2DS was found in 11.1% of the patients. Furthermore, 74.1% of the patients had a congenital heart defect, the most common of which was tetralogy of Fallot (40.7%). Hypocalcemia was observed in 40.7% of the patients. A low T-cell count was observed in 66.7% of the patients, whereas 18.5% had low immunoglobulin levels. Cognitive assessments revealed that four out of six evaluated patients (66.7%) had an intellectual disability, as evidenced by intellectual quotient scores less than 70. The remaining two patients (33.3%) had a borderline intellectual function. Conclusion: Tetralogy of Fallot, hypocalcemia, immunologic defects, and cognitive impairment were common among our patients. To address the potential multisystem involvement, we recommend that all affected individuals undergo a comprehensive evaluation by a multidisciplinary care team.

ABSTRACT

We investigated the hemodynamic parameters of pediatric PDA patients and focused on the influence of PDA size on pulmonary arterial pressure and the prevalence of pulmonary hypertension. A total of 52 patients aged between 2 months and 20 years who received transcatheter closure of a PDA from January 2018 to June 2022 in our institution were retrospectively recruited. Their hemodynamic parameters collected both by echocardiography and by cardiac catheterization were analyzed to delineate the influence of PDA size on the pulmonary vascular system. The echocardiographic-based ductal size and indexed PDA size were 1.93 mm (1.15-6 mm) and 4.05 mm/m2 (2.03-25.47 mm/m2), respectively. The pulmonary artery pressure measured was 20.83 mmHg (8-45 mmHg). We found a positive correlation between indexed PDA size and mean pulmonary arterial pressure (mPAP) (Pearson correlation coefficient = 0.47, p < 0.001). A subgroup analysis showed that 28 patients (53.8%) developed pulmonary hypertension (PH) (defined as mPAP > 20 mmHg). The median age of the PH group was 1.02 years [range: 0.19-8.64], which was significantly younger than the non-PH group's median age of 3.43 years [range: 0.42-19.96] (p = 0.001). The indexed PDA size for the PH group, 4.69 mm/m2, was significantly higher than that of the non-PH group, 3.2 mm/m2 (p = 0.004). The major risk factor for patients with PH was the PDA/BSA index, with an OR of 2.181 (95% CI, 1.224-3.887). Our demographic data showed younger patients with a higher PDA/BSA index are more likely to develop pulmonary hypertension.

ABSTRACT

Lipid droplets (LDs) and their autophagy by lysosomes are closely related to a variety of physiological and pathological conditions. Therefore, identifying and tracking LDs and the dynamic process of autophagy can provide useful information for the diagnostics and treatment of related diseases. However, few organic small molecule-based fluorescent probes can specifically recognize LDs and dynamically track their autophagy process. Herein, we synthesized a "discoloration" fluorescent bioprobe DPABP-BI with distinguishable features including red fluorescence emission (630 nm), large Stokes shift (145 nm), two-photon excitation and outstanding photostability and biocompatibility. In particular, LDs could be specifically identified via the red fluorescence emission of DPABP-BI (colocalization constant of 0.98), while autophagolysosomes could be visualized via the green fluorescence emission of its acid-hydrolyzed product (colocalization constant of 0.90) to track the autophagy dynamic process. In addition, DPABP-BI enabled the specific recognition of fatty substances in zebrafish larvae. In this study, a two-photon excited red light small molecule probe was constructed to identify LDs and track their autophagy dynamic process by changing the fluorescence emission wavelength.

ABSTRACT

Williams syndrome (WS) is a rare genetic disorder caused by the microdeletion of chromosome 7q11.23. Cardiovascular defects (CVDs) are the leading causes of morbidity and mortality in patients with WS. The most common CVD in patients with WS is supravalvular aortic stenosis (SVAS), which recovers spontaneously similar to branch pulmonary stenosis (PS). Recently, conventional beliefs, such as SVAS improving rather than worsening in WS, have been challenged. This study thoroughly reviews the medical records of 30 patients with a molecular diagnosis of WS. We followed up these patients at Taipei MacKay Memorial Hospital from January 1999 to December 2021. The long-term outcomes of cardiovascular lesions as well as the change in peak pressure gradient in obstructive cardiovascular lesions over time were studied. Among these 30 patients, the most common cardiovascular lesion was SVAS (50.0%), followed by branch PS (36.7%). During the follow-up period, severe SVAS was aggravated (p = 0.021). The peak pressure gradient decreased from 38.4 to 25.3 mmHg (p = 0.001) in patients with branch PS. Among patients with WS, those with severe SVAS deteriorated over time, whereas those with branch PS improved on their own. In patients with WS who presented with branch PS, no disease-specific intervention was needed.

ABSTRACT

BACKGROUND: Prolongation of the QT interval is associated with the risk of sudden infant death syndrome. QT interval differs depending on age at the time of screening. Screening protocols have yet to be established for Taiwanese patients. OBJECTIVES: To construct QT interval reference values during early infancy, to investigate whether QT interval change differs according to age calculation methods, and to identify an optimal QT correction method and associated infant factors. METHODS: Electrocardiographic readings and QT intervals were recorded cross-sectionally in 595 healthy infants and screened prospectively for long QT interval. Corrected QT intervals with Bazett's (QTc-B) and Fridericia's (QTc-F) formulas were compared by post-natal and post-menstrual screening age, sex, body mass index (BMI), heart rate (HR), birth and family history. RESULTS: QTc-B and QTc-F decreased in the second month (31-60 days), and peaked in the third month (61-90 days). QT interval length was similar between post-menstrual and post-natal ages for QTc-B. Simple linear regression showed that post-menstrual age, post-natal age, HR and BMI were associated with QTc-F, while only sex and HR were associated with QTc-B. Although both QTc-B and QTc-F were significantly associated with HR, QTc-B was less affected by HR than QTc-F (ß = -0.1, p < 0.05 for QTc-B vs. ß = -0.3, p < 0.001 for QTc-F). Female infants tended to have slightly longer QTc intervals. CONCLUSIONS: QT interval in early infancy changed physiologically, peaking in the third month. The rate of QT change was not affected by different age correction methods. QTc-B was less affected by age, BMI and HR, although differences in sex should be noted.

ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: Lung carcinoma (LC) is not only a kind of disease that seriously threatens human life but also an intractable problem in modern medicine. Jiao'e Mixture (JEM) is an innovative Chinese medicine formula with Chinese patent, which is composed of two herbal extracts with a specific ratio-zedoary turmeric oil and medicinal Zanthoxylum bungeanum Maxim(Z. bungeanum Maxim) seeds oil (ZMSO). Zedoary turmeric oil is extracted from dried rhizomes of Curcuma wenyujin Y.H.Chen et C. Ling, which has been reported have an anti-cancer effects. Medicinal ZMSO is a by-product of Z. bungeanum Maxim, refined from kernel shell separation, modern cold soaking and refining technology; JEM is used to treat Lung carcinoma (LC) patients in folk for many years. However, its therapeutic mechanisms for treating LC have not been fully explored. AIM OF THE STUDY: The purpose of this study was to explore the therapeutic mechanisms of JEM for treating LC. MATERIALS AND METHODS: The action mechanism of JEM in LC treatment was analysed by comprehensive network pharmacology approach combined with experimental validation (in vivo and in vitro). RESULTS: Seventeen active compounds and 457 related targets were collected from the HERB, TCMSP, and Swiss Target Prediction platforms. Nine hundred and thirty-eight LC related targets were obtained from Gene Cards and OMIM databases. Finally, 140 overlapping targets were obtained, which representing the target of JEM in LC treatment. The pathway analysis showed that PI3K-AKT could be a potential pathway for JEM in LC treatment. In vivo results presented that JEM had a good effect in inhibiting the growth of LC tumour cells with high efficacy and low toxicity. In vitro experiments validated that JEM had inhibited LC cells' proliferation, migration and invasion, and had induced cell apoptosis mainly via PI3K/Akt signalling pathways. CONCLUSION: The anti-LC activity of JEM might via regulating the PI3K-AKT signalling pathways.This study may provide further evidence for the potential use of JEM in LC treatment.

ABSTRACT

BACKGROUND: Cardiac abnormalities have been observed in patients with mucopolysaccharidosis type II (MPS II). The aim of this study was to investigate the cardiac features and natural progression of Taiwanese patients with MPS II, and evaluate the impact of enzyme replacement therapy (ERT) on cardiac structure and function. METHODS: The medical records and echocardiograms of 48 Taiwanese patients with MPS II (median age, 6.9 years; age range, 0.1-27.9 years) were reviewed. The relationships between age and each echocardiographic parameter were analyzed. RESULTS: The mean z-scores of left ventricular mass index (LVMI), interventricular septum diameter in diastole (IVSd), left ventricular posterior wall diameter in diastole (LVPWd), and aortic diameter were 1.10, 2.70, 0.95 and 1.91, respectively. Z scores > 2 were identified in 33%, 54%, 13%, and 46% for LVMI, IVSd, LVPWd, and aortic diameter, respectively. The most prevalent cardiac valve abnormality was mitral regurgitation (MR) (56%), followed by aortic regurgitation (AR) (33%). The severity of mitral stenosis (MS), MR, aortic stenosis (AS), AR, and the existence of valvular heart disease were all positively correlated with increasing age (p < 0.01). We also compared the echocardiographic parameters between two groups: (1) 12 patients who had up to 17 years of follow-up echocardiographic data without ERT, and (2) nine patients who had up to 12 years of follow-up data with ERT. The results showed that z-score changes of LVMI significantly improved in the patients who received ERT compared to those who did not receive ERT (0.05 versus 1.52, p < 0.05). However, the severity score changes of MS, MR, AS, and AR all showed gradual progression in both groups (p > 0.05). CONCLUSIONS: High prevalence rates of valvular heart disease and cardiac hypertrophy were observed in the MPS II patients in this study. The existence and severity of cardiac hypertrophy and valvular heart disease in these patients worsened with increasing age, reinforcing the concept of the progressive nature of this disease. ERT for MPS II appeared to be effective in stabilizing or reducing the progression of cardiac hypertrophy, but it only had a limited effect on valvulopathy.

ABSTRACT

BACKGROUND: Cardiovascular abnormalities have been observed in patients with mucopolysaccharidosis (MPS) of any type, with the most documented abnormalities being valvular regurgitation and stenosis and cardiac hypertrophy. Only a few studies have focused on aortic root dilatation and the long-term effects of enzyme replacement therapy (ERT) in these patients. METHODS: We reviewed echocardiograms of 125 Taiwanese MPS patients (age range, 0.1 to 19.1 years; 11 with MPS I, 49 with MPS II, 25 with MPS III, 29 with MPS IVA, and 11 with MPS VI). The aortic root diameter was measured at the sinus of Valsalva. RESULTS: Aortic root dilatation (z score >2) was observed in 47% of the MPS patients, including 66% of MPS IV, 51% of MPS II, 45% of MPS VI, 28% of MPS III, and 27% of MPS I patients. The mean aortic root diameter z score was 2.14 (n = 125). The patients with MPS IV had the most severe aortic root dilatation with a mean aortic root diameter z score of 3.03, followed by MPS II (2.12), MPS VI (2.06), MPS III (1.68), and MPS I (1.03). The aortic root diameter z score was positively correlated with increasing age (n = 125, p < 0.01). For the patients with MPS II, III, and IV, aortic root diameter z score was also positively correlated with increasing age (p < 0.01). For 16 patients who had received ERT and had follow-up echocardiographic data (range 2.0-16.2 years), the mean aortic root diameter z score change was -0.46 compared to baseline (baseline 2.49 versus follow-up 2.03, p = 0.490). CONCLUSIONS: Aortic root dilatation was common in the patients with all types of MPS, with the most severe aortic root dilatation observed in those with MPS IV. The severity of aortic root dilatation worsened with increasing age, reinforcing the concept of the progressive nature of this disease. ERT for MPS appears to stabilize the progression of aortic root dilatation.

ABSTRACT

BACKGROUND: Prospective registry studies of congenital heart disease (CHD)-associated pulmonary artery hypertension (PAH) are rare. We established a multicenter registry of CHD-PAH: the TACHYON (TAiwan Congenital Heart disease associated with pulmonarY arterial hypertension) registry. METHODS: The prospective TACHYON registry was initiated in January 2016. Nine pediatric cardiology centers with 99 patients were included. Using this database, we evaluated clinical characteristics and outcomes. RESULTS: Twelve patients with incomplete data were excluded. For the remaining 87 patients, mean age of enrollment was 37.4(SD 18.2) years, and the male to female ratio was 60:27. PAH after defect closure accounted for 46 (52.9%) and Eisenmenger syndrome for 30 (34.5%) cases. Atrial septal defect was the most common (48.3%) disease, followed by ventricular septal defect. Mean pulmonary artery pressure was 56.7 (SD 19.4) mmHg. PAH-targeted therapy was used in 95.4% of patients. Sildenafil and bosentan were the most common drugs. After mean 23.9 months of follow-up, the 2-year Kaplan-Meier survival rate was 93.2%. According to univariate Cox regression analysis, significant risk factors included right heart failure signs, symptom progression, high-risk baseline N-terminal pro-brain natriuretic peptide (BNP)/BNP, high-risk baseline 6-min walking distance (6MWD), and high baseline hemoglobin/hematocrit level. Using the three noninvasive parameters (functional class, 6MWD, NT-pro BNP/BNP) proposed by the European Society of Cardiology, the total number of high-risk criteria predicted survival rate reliably. CONCLUSIONS: Using the TACHYON registry is feasible, but the physicians' adherences to guidelines are unsatisfactory. Midterm outcomes of PAH-target therapy are favorable and predictable using noninvasive parameters.

ABSTRACT

Currently available fetal echocardiographic reference values are derived mainly from North American and European population studies, and there is a lack of reference z-score for fetal echocardiographic measurement in Asian populations. The aim of this study was to establish normal ranges of echocardiographic measurements and z-scores in healthy Asian fetuses. A total of 575 healthy pregnant Taiwanese with an estimated gestational age from 14 to 38 weeks were enrolled voluntarily for this observational study. Standard two-dimensional echocardiography was performed to obtain measurements of the cardiac chambers and great arteries of the developing fetuses. In contrast to past studies, our sample was more evenly distributed for estimated gestational age (p<0.001). We present percentile graphs for 13 fetal echocardiographic measurements from the knowledge of estimated gestational age, biparietal distance, head circumference, abdominal circumference, and femur length. Most cardiac structures and developmental markers had linear models as the best-fitting, except for transverse aortic isthmus by estimated gestational age and transverse ductus arteriosus by femur length. Our findings indicate that estimated gestational age was generally the best model for fetal heart development, while head circumferences could be used as an optimal developmental marker to predict left atrium, right atrium, right ventricle, pulmonary annulus, and ductus arteriosus. Lastly, we developed nomograms for each of the 13 fetal heart measurements by each developmental markers. This is the first study providing echocardiographic reference ranges and nomograms for Asian fetuses. Computing z-scores from nomograms helps in standardizing comparisons and adds additional prognostic information to the diagnosis of congenital heart disease.

ABSTRACT

BACKGROUND: Mucopolysaccharidoses (MPSs) are a group of rare inherited metabolic disorders that can damage various organs, including the heart. Cardiac abnormalities have been observed in patients with all MPS types, with the most documented abnormalities being cardiac valvular regurgitation and stenosis, valvular thickening, and hypertrophic cardiomyopathy. METHODS: Cardiac features of 53 Taiwanese patients with MPS (31 men and 22 women; age range 1.1-34.9 years; seven with MPS I, 16 with MPS II, nine with MPS III, 14 with MPS IVA, and seven with MPS VI) were evaluated using two-dimensional speckle-tracking echocardiography and conventional echocardiography. RESULTS: The mean z scores of the global longitudinal strain (GLS), left ventricular mass index (LVMI), interventricular septum diameter in diastole (IVSd), left ventricular posterior wall diameter in diastole (LVPWd), and aortic diameter of the 53 patients with MPS were 1.71, 0.35, 1.66, 1.03, and 3.15, respectively. Furthermore, z scores >2 were identified in 45%, 13%, 40%, 13%, and 70% of the GLS, LVMI, IVSd, LVPWd, and aortic diameter, respectively. The most severe GLS was observed in those with MPS VI, followed by in those with MPS II and MPS I. The GLS z score was positively correlated with the LVMI z score (p < 0.01). Moreover, diastolic dysfunction (reversed ratio between early and late (atrial) ventricular filling velocity (E/A ratio < 1)) was identified in 12 patients (23%). Ejection and shortening fractions were abnormal in four (8%) and seven (13%) patients, respectively. Mitral regurgitation (MR) (92%) was the most common valvular heart disease, followed by aortic regurgitation (AR) (57%), mitral stenosis (MS) (21%), and aortic stenosis (AS) (15%). The z scores of the GLS and LVMI and severity scores of the MS, MR, AS, and AR were all positively correlated with increasing age (p < 0.05). Twenty patients (38%) had a left ventricular remodeling pattern. CONCLUSIONS: The most significant left ventricular myocardial deformation, hypertrophy and valvular heart disease were observed in the patients with MPS VI, II, and I, followed by those with MPS IV; in contrast, patients with MPS III had the mildest manifestations. Cardiac abnormalities in patients with MPS worsened with increasing age in accordance with the progressive nature of this disease.

ABSTRACT

Objective To explore the consistency between identification diagnosis and pre-identification clinical diagnosis of patients with mental disorder undergoing forensic psychiatry identification. Methods The identification data of 1 369 appraised individuals who underwent criminal responsibility identification carried out by the Forensic Institute of Second Affiliated Hospital of Jining Medical University from 2014 to 2017 were collected retrospectively using self-designed investigation data sorting table. A comparative analysis of the mental disorder diagnosis results of expert opinion and past clinical diagnosis results was made. Results Among 1 369 appraised individuals, 964 cases (70.4%) were identified and diagnosed with mental disorder and 405 cases (29.6%) without mental disorder. Among the former, 63.3% (610 cases) were clinically diagnosed, which was higher than 43.2% (175 cases, P<0.05) in the latter. Among the various mental disorders that had been identified and diagnosed, patients with hysteria, stress, and neurosis had the highest proportion of clinical diagnoses (86.7%), while patients with mental retardation had the lowest proportion of clinical diagnoses (9.6%). Schizophrenia had the highest overall consistency rate of identification diagnosis and clinical diagnosis (98.4%), while personality and behavior disorder had the lowest (33.3%). The overall consistency rate between clinical diagnosis and identification diagnosis of the mental disorder group was 84.1%, and the Kappa value was 0.759. Compared with clinical diagnosis, the consistency rate between inpatient diagnosis and identification diagnosis was higher (85.9%, P<0.05). Conclusion In forensic psychiatry identification that provides data of past clinical diagnosis and treatment, a high consistency between identification diagnosis and clinical diagnosis of the appraised individual who is identified and diagnosed with mental disorder exists. Clinical diagnosis (especially the inpatient diagnosis) has a relatively good reference value for forensic psychiatry identification.

ABSTRACT

BACKGROUND: Persistent left superior vena cava (PLSVC) is a vascular anomaly that is usually asymptomatic and detected incidentally. The incidence of PLSVC has seldom been evaluated in normal populations. In this study, we determined the incidence of PLSVC in a normal neonatal population using transthoracic echocardiography. We also evaluated the associations between PLSVC and asymptomatic congenital heart diseases. MATERIALS AND METHODS: In this retrospective study, we identified healthy neonates based on echocardiography results from 2008 to 2017. Based on the echocardiography findings, we categorized the patients into a PLSVC group and a control group (patients without PLSVC). Chi-square and logistic regression tests were used for data analysis. RESULTS: Of the 19,488 neonates assessed in this study, 56 were found to have PLSVC, and the remaining 19,432 neonates comprised the control group. The incidence of PLSVC was 0.29% in our population. In the PLSVC group, 3.6% of the patients exhibited bicuspid aortic valves, and 10.7% of the patients exhibited secundum-type atrial septal defects. Both the incidence and association of these conditions were higher in the PLSVC group than in the control group. CONCLUSIONS: Based on the echocardiography examination results, we discovered that the incidence of PLSVC in Taiwanese neonates was 0.29%. Although the neonates with PLSVC were asymptomatic and exhibited no health concerns, they were associated with higher incidence rates of bicuspid aortic valves and secundum-type atrial defects. Additional follow-up and evaluation regarding these findings may be warranted.

ABSTRACT

BACKGROUND: Mucopolysaccharidosis type III (MPS III), or Sanfilippo syndrome, is caused by a deficiency in one of the four enzymes involved in the lysosomal degradation of heparan sulfate. Cardiac abnormalities have been observed in patients with all types of MPS except MPS IX, however few studies have focused on cardiac alterations in patients with MPS III. METHODS: We reviewed medical records, echocardiograms, and electrocardiograms of 26 Taiwanese patients with MPS III (five with IIIA, 20 with IIIB, and one with IIIC; 14 males and 12 females; median age, 7.4 years; age range, 1.8-26.5 years). The relationships between age and each echocardiographic parameter were analyzed. RESULTS: Echocardiographic examinations (n = 26) revealed that 10 patients (38%) had valvular heart disease. Four (15%) and eight (31%) patients had valvular stenosis or regurgitation, respectively. The most prevalent cardiac valve abnormality was mitral regurgitation (31%), followed by aortic regurgitation (19%). However, most of the cases of valvular heart disease were mild. Three (12%), five (19%) and five (19%) patients had mitral valve prolapse, a thickened interventricular septum, and asymmetric septal hypertrophy, respectively. The severity of aortic regurgitation and the existence of valvular heart disease, aortic valve abnormalities and valvular stenosis were all positively correlated with increasing age (p < 0.05). Z scores > 2 were identified in 0, 38, 8, and 27% of left ventricular mass index, interventricular septal end-diastolic dimension, left ventricular posterior wall end-diastolic dimension, and aortic diameter, respectively. Electrocardiograms in 11 patients revealed the presence of sinus arrhythmia (n = 3), sinus bradycardia (n = 2), and sinus tachycardia (n = 1). Six patients with MPS IIIB had follow-up echocardiographic data at 1.9-18.1 years to compare with the baseline data, which showed some patients had increased thickness of the interventricular septum, as well as more patients had valvular abnormalities at follow-up. CONCLUSIONS: Cardiac involvement in MPS III is less common and milder compared with other types of MPS. The existence of valvular heart disease, aortic valve abnormalities and valvular stenosis in the patients worsened with increasing age, reinforcing the concept of the progressive nature of this disease.

ABSTRACT

Objective@#To evaluate the application value of quantitative computed tomography for evaluation of changes in abdominal fat after laparoscopic Roux-en-Y gastric bypass in obese patients.@*Methods@#The retrospective and descriptive study was conducted. The clinical data of 52 obese patients who underwent laparoscopic Roux-en-Y gastric bypass in the Third Medical Center of Chinese PLA General Hospital from March 2011 to February 2012 were collected. There were 24 males and 28 females, aged (43±9)years, with the range of 23-62 years. All the 52 patients underwent laparoscopic Roux-en-Y gastric bypass. Observation indicators: (1) surgical and postoperative conditions; (2) changes in anthropometric indices; (3) follow-up. Follow-up using outpatient examination was performed to detect complications of patients at 1, 3, 6, 12 months after surgery up to February 2013. Measurement data with normal distribution were represented as Mean±SD, repeated measurement data were analyzed using repeated ANOVA. Count data were represented as absolute numbers.@*Results@#(1) Surgical and postoperative conditions: all the patients underwent laparoscopic Roux-en-Y gastric bypass successfully, without conversion to open surgery. The volume of intraoperative blood loss, operation time, and duration of hospital stay were (25±11)mL, (78±14)minutes, and (11±2)days. (2) Changes in anthropometric indices: the body mass index (BMI), fat mass, free fat mass, total abdominal fat volume (TAFV), total subcutaneous fat volume (TSFV), and total visceral fat volume (TVFV) of all the 52 patients were (31.8±1.8)kg/m2, (39.4±4.1)kg, (50.2±6.0)kg, (11 703±3 899)cm3, (7 418±2 969)cm3, and (4 314±1 692)cm3 before surgery, (28.5±1.4)kg/m2, (33.0±1.1)kg, (49.7±4.6)kg, (11 016±3 713)cm3, (7 044±2 970)cm3, (3 969±1 443)cm3 at 3 months after surgery, (27.1±1.7)kg/m2, (30.2±1.3)kg, (45.4±3.1)kg, (9 406±4 452)cm3, (6 442±3 307)cm3, and (2 964±1 694)cm3 at 6 months after surgery, (24.4±2.4)kg/m2, (32.6±1.1)kg, (48.6±2.7)kg, (7 612±3 029)cm3, (5 623±2 650)cm3, and (1 826±360)cm3 at 12 months after surgery, respectively, there were significant differences in the changes of these indices (F=130.2, 30.3, 4.9, 25.6, 11.9, 16.5, P<0.05).

ABSTRACT

BACKGROUND: Cardiac abnormalities have been observed in patients with mucopolysaccharidosis (MPS) of any type, with the most documented abnormalities being valvular heart disease and cardiac hypertrophy. However, few studies have focused on the cardiac features of MPS IVA. METHODS: We reviewed the medical records, echocardiograms, and electrocardiograms of 32 Taiwanese patients with MPS IVA (16 males and 16 females; median age, 10.8 years; age range, 1.1 to 29.1 years) as well as the echocardiographic data of six patients who received enzyme replacement therapy (ERT) for 3-6 years. RESULTS: Echocardiographic examinations (n = 32) revealed mean z scores of left ventricular mass index (LVMI), interventricular septum diameter in diastole (IVSd), left ventricular posterior wall diameter in diastole (LVPWd), and aortic diameter of 0.94, 2.70, 0.39, and 3.26, respectively. Z scores > 2 were identified in 25%, 50%, 29%, and 69% of the LVMI, IVSd, LVPWd, and aortic diameter values, respectively. Diastolic dysfunction [reversed ratio between early and late (atrial) ventricular filling velocity (E/A ratio < 1)] was identified in four patients (13%), however, the ejection fraction was normal (50-75%) in all of the patients. Sixteen patients (50%) had valvular heart disease and most were of mild degree. Fourteen (44%) had valvular stenosis, and 10 (31%) had regurgitation. The z scores of LVMI, IVSd, LVPWd, and aortic diameter, the severity scores of aortic stenosis and regurgitation, and the existence of a thickened interventricular septum were all positively correlated with increasing age (p < 0.05). For the 14 patients with valve thickening, the z scores of LVMI, IVSd and aortic diameter were all larger than those of the 18 patients without valve thickening (p < 0.05). For two patients who started ERT at a younger age (1.4 and 2.8 years, respectively), the z scores for LVMI, IVSd, and LVPWd all decreased after ERT. CONCLUSIONS: A large proportion of the patients with MPS IVA had valvular heart disease and cardiac hypertrophy. Cardiac abnormalities worsened with increasing age in accordance with the progressive nature of this disease. ERT appeared to be effective in stabilizing or reducing cardiac hypertrophy, and better results may have been associated with starting ERT at a younger age.

ABSTRACT

Neonatal Marfan syndrome, in contrast to classical Marfan syndrome, is characterized by rapidly progressive multi-valvular cardiac disease and death from congestive heart failure, typically within the first year of life. Due to the rarity of this condition, treatment for neonatal Marfan syndrome has not been well studied. In this report, a combination of losartan and propranolol reduced the aortic root dilatation rate after three months of losartan therapy. Genetic analysis in this patient revealed a mutation in exon 25 of the FBN1 gene, which typically results in a shorter life expectancy. However, the patient's heart failure was controlled by losartan, propranolol and other anti-congestive medications, which may have prolonged his survival.
