Abstract PDF PubReader ePub

X-linked adrenoleukodystrophy (X-ALD) occurs due to mutations in the ABCD1 gene that encodes the peroxisomal membrane protein peroxisomal transporter ATP-binding cassette sub-family D member 1 (ABCD1). Degradation of very long-chain fatty acids in peroxisomes is impaired owing to ABCD dysfunction, subsequently leading to adrenomyeloneuropathy, cerebral adrenoleukodystrophy, and adrenal insufficiency. X-ALD frequently induces idiopathic Addison's disease in young male patients. Here, we confirmed the diagnosis of X-ALD in a young male patient with primary adrenal insufficiency, and identified a novel ABCD1 gene mutation (p.Trp664*, c.1991 G>A).

Background

Despite the beneficial effect of fibroblast growth factor 21 (FGF21) on metabolic disease, there are concerns about adverse effects on bone metabolism, supported by animal studies. However, a recent human study showed the positive association between serum FGF21 level and bone mineral density (BMD) in healthy premenopausal women. We undertook this study to examine the association between FGF21 level and BMD in healthy postmenopausal Korean women who are susceptible to osteoporosis.

Methods

We used data of 115 participants from a cohort of healthy postmenopausal women (>50 years old) to examine the association between serum FGF21 level and BMD. The clinical characteristics were obtained from the participants, and blood testing and serum FGF21 testing were undertaken. BMD of the lumbar spine, femoral neck and total hip area, and bone markers were used in the analyses.

Results

The mean age of the participants was 60.2±7.2 years. Serum FGF21 levels showed negative correlation with BMD and T-scores in all three areas, but there were no statistically significant differences. Multivariate analyses with adjustment for age and body mass index also did not show significant association between serum FGF21 level and BMD. In addition, serum FGF21 level also showed no correlation with osteocalcin and C-telopeptide levels.

Conclusion

In our study, serum FGF21 level showed no significant correlation with BMD and T-scores.

Abstract PDF PubReader

Glucokinase maturity-onset diabetes of the young (GCK-MODY) represents a distinct subgroup of MODY that does not require hyperglycemia-lowering treatment and has very few diabetes-related complications. Three patients from two families who presented with clinical signs of GCK-MODY were evaluated. Whole-exome sequencing was performed and the effects of the identified mutations were assessed using bioinformatics tools, such as PolyPhen-2, SIFT, and in silico modeling. We identified two mutations: p.Leu30Pro and p.Ser383Leu. In silico analyses predicted that these mutations result in structural conformational changes, protein destabilization, and thermal instability. Our findings may inform future GCK-MODY diagnosis; furthermore, the two mutations detected in two Korean families with GCK-MODY improve our understanding of the genetic basis of the disease.

Abstract PDF Supplementary Material PubReader: Background
Multipotent mesenchymal stem cells can differentiate into adipocytes or osteoblasts through closely regulated lineage-control processes. However, adipocyte precursor cells release preadipocyte factor 1 (Pref-1), which inhibits the differentiation of mesenchymal stem cells into mature adipocytes and osteoblasts. Previous studies have also reported an inverse association between Pref-1 levels and bone mineral density (BMD) among patients with anorexia nervosa.
Methods
In this retrospective study, we examined the correlations between Pref-1 levels and BMD among 124 healthy postmenopausal women (>50 years old). The patients had provided information regarding their clinical characteristics, and underwent blood testing and serum Pref-1 testing.
Results
The subjects' mean age was 59.9±7.1 years and the median time since menopause onset was 9.1 years. A history of osteoporotic fracture was identified in 23 subjects (19%). Serum Pref-1 levels were not significantly correlated with BMD values at the lumbar spine (R²=0.038, P=0.109), femur neck (R²=0.017, P=0.869), and total hip (R²=0.041, P=0.09), and multivariate analyses with adjustment for age and body mass index also did not detect any significant correlations. Subgroup analyses according to a history of fracture also did not detect significant associations between Pref-1 levels and BMD values.
Conclusion
In our study population, it does not appear that serum Pref-1 levels are significantly associated with BMD values and osteoporosis.

Background

The prevalence of type 2 diabetes in elderly people has increased dramatically in the last few decades. This study was designed to clarify the clinical characteristics of type 2 diabetes in patients aged ≥80 years according to age of onset.

Methods

We reviewed the medical records of 289 patients aged ≥80 years with type 2 diabetes at the outpatient diabetes clinics of Kangwon National University Hospital from September 2010 to June 2014. We divided the patients into middle-age-onset diabetes (onset before 65 years of age) and elderly-onset diabetes (onset at 65+ years of age).

Results

There were 141 male and 148 female patients. The patients had a mean age of 83.2±2.9 years and the mean duration of diabetes was 14.3±10.4 years. One hundred and ninety-nine patients had elderly-onset diabetes. The patients with elderly-onset diabetes had a significantly lower frequency of diabetic retinopathy and nephropathy, lower serum creatinine levels, lower glycated hemoglobin (HbA1c) levels, and similar coronary revascularization and cerebral infarction rates compared to those with middle-age-onset diabetes. There was no frequency difference in coronary revascularization and cerebral infarction and HbA1c levels between three subgroups (<5, 5 to 15, and ≥15 years) of diabetes duration in elderly onset diabetes. However, both in the elderly onset diabetes and middle-age-onset diabetes, the cumulative incidence of retinopathy was increasing rapidly according to the duration of diabetes.

Conclusion

We report that individuals with elderly-onset diabetes have a lower frequency of diabetic retinopathy and nephropathy and similar cardiovascular complications compared to those with middle-age-onset diabetes.

Background

Dipeptidyl peptidase 4/CD26 (DPP-4) is a widely expressed cell surface serine protease. DPP-4 inhibitors, one of common anti-diabetic agents play a protective role in bone metabolism in recent studies. A soluble form of DPP-4 is found in serum, and exhibits DPP-4 enzymatic activity. However, the physiological role of serum or soluble DPP-4 and its relationship with DPP-4 enzymatic function remain poorly understood. The aims of current study were to determine the association between serum DPP-4 activity and bone mineral density (BMD) in postmenopausal women.

Methods

We recruited data and serum samples from 124 consecutive healthy postmenopausal women aged >50 years. We divided study subjects into obese (body mass index [BMI] ≥25 kg/m²) and non-obese (BMI <25 kg/m²) postmenopausal women and examined the correlation between serum DPP-4 activity and clinical variables in each groups.

Results

A total of 124 postmenopausal women was enrolled, with a mean age of 59.9±7.1 years. The mean BMI of the study patients was 24.4±2.8 kg/m². Regarding bone turnover markers, serum DPP-4 activity was positively correlated with serum calcium concentrations, intact parathyroid hormone, and serum C-telopeptide levels in all of the study subjects. However, there was no association between serum DPP-4 activity and BMD in the spine or femoral neck in all of the study subjects. Serum DPP-4 activity was negatively correlated (R=−0.288, P=0.038) with BMD of the spine in obese postmenopausal women.

Conclusion

This study demonstrated for the first time that serum soluble DPP-4 activity was negatively correlated with BMD in obese postmenopausal women.
