Background
To examine whether glycated hemoglobin (HbA1c) test would be a suitable screening tool for detecting high-risk subjects for diabetes compared to oral glucose tolerance test (OGTT) according to accompanied central obesity.
Methods
In this prospective population-based cohort study, both OGTT and HbA1c tests were performed and continued every 2 years up to 12 years among individuals with non-diabetic state at baseline (aged 40 to 69 years, n=7,512). Incident diabetes was established by a doctor, HbA1c ≥6.5%, and/or fasting plasma glucose (FPG) ≥126 mg/dL, and/or 2-hour postprandial glucose (2hPG) level based on OGTT ≥200 mg/dL. Discriminative capacities of high HbA1c (≥5.7%) versus high 2hPG (≥140 mg/dL) for predicting incident diabetes were compared using Cox-proportional hazard regression and C-index.
Results
During the median 11.5 years of follow-up period, 1,341 (17.6%) developed diabetes corresponding to an incidence of 22.1 per 1,000 person-years. Isolated high 2hPG was associated with higher risk for incident diabetes (hazard ratio [HR], 4.29; 95% confidence interval [CI], 3.56 to 5.17) than isolated high HbA1c (HR, 2.79; 95% CI, 2.40 to 3.26; P<0.05). In addition, high 2hPG provided better discriminatory capacity than high HbA1c (C-index 0.79 vs. 0.75, P<0.05). Meanwhile, in subjects with central obesity, the HR (3.95 [95% CI, 3.01 to 5.18] vs. 2.82 [95% CI, 2.30 to 3.46]) and discriminatory capacity of incident diabetes (C-index 0.75 vs. 0.75) between two subgroups became comparable.
Conclusion
Even though the overall inferior predictive capacity of HbA1c test than OGTT, HbA1c test might plays a complementary role in identifying high risk for diabetes especially in subjects with central obesity with increased sensitivity.

Background

The chronic use of glucocorticoids (GC) suppresses function of the hypothalamic-pituitary-adrenal axis and often results in secondary adrenal insufficiency (AI). The present study aimed to determine the recovery rate of adrenal function in patients with secondary AI within 1 to 2 years and to assess the factors predictive of adrenal function recovery.

Methods

This was a retrospective observational study that enrolled patients diagnosed with GC-induced secondary AI between 2007 and 2013. AI was defined by peak serum cortisol levels <18 µg/dL during a standard-dose short synacthen test (SST). A follow-up SST was performed after 1 to 2 years, and responders were defined as those with adrenocorticotropic hormone (ACTH)-stimulated peak serum cortisol levels ≥18 µg/dL.

Results

Of the total 34 patients diagnosed with GC-induced secondary AI at first, 20 patients (58.8%) recovered normal adrenal function by the time of the follow-up SST (median follow-up period, 16.5 months). Although the baseline serum ACTH and cortisol levels at the first SST did not differ between responders and non-responders, the incremental cortisol response during the first SST was higher in responders than that of non-responders (7.88 vs. 3.56, P<0.01). Additionally, higher cortisol increments during the first SST were an independent predictive factor of the adrenal function recovery (odds ratio, 1.58; 95% confidence interval, 1.02 to 2.46; P<0.05).

Conclusion

In the present study, adrenal function recovery was achieved frequently in patients with GC-induced secondary AI within 1 to 2 years. Additionally, an incremental cortisol response at the first SST may be an important predictive factor of adrenal function recovery.

AbstractAbstract PDF
BACKGROUND
The purpose of this study was to investigate the prevalence of rhabdomyolysis and its association with both clinical course and prognosis and to evaluate the factors associated with rhabdomyolysis in patients with hyperglycemic emergencies. METHODS: We reviewed the medical records of patients with hyperglycemic emergencies who visited our hospital from May 2003 to April 2010. We assessed the clinical characteristics, biochemical profiles and clinical course of patients and analyzed these data according to the presence of rhabdomyolysis. RESULTS: The prevalence of rhabdomyolysis was 29 patients (28.4%) among 102 patients. Mean serum osmolarity, glucose and serum creatinine levels were higher in patients with rhabdomyolysis than those without rhabdomyolysis. Patients with rhabdomyolysis had higher rates of hemodialysis and mortality than those without the condition. The factors associated with rhabdomyolysis in the hyperglycemic emergency state were increased serum osmolarity and APACHE II score on admission (P < 0.05). CONCLUSION: Rhabdomyolysis commonly occurred in patients with hyperglycemic emergencies and this could aggravate their clinical course and increase mortality.

AbstractAbstract PDF
Here we describe a male patient who attained normal height despite combined hypopituitarism with an abnormal growth hormone-insulin-like growth factor (IGF)-I axis. When he was an 18-year-old, he presented with a short stature and underdeveloped external genitalia. The patient had not undergone normal pubertal development and he displayed a height below the fifth percentile. Hormonal and radiological studies revealed the findings of severe anterior pituitary hormone deficiency and an atrophic pituitary gland. There had been no recent follow-ups with the patient or medical treatment since that time. In the current presentation, the patient, now 22 years of age, had attained normal height, yet he remained prepubertal and showed manifestations of delayed bone age and combined hypopituitarism. In addition, the patient's IGF-II levels were increased for his age.
