Insulin-like growth factor-I (IGF-I) plays a pivotal role in the diagnosis and treatment of growth hormone (GH) excess or deficiency. The GH study group of the Korean Endocrine Society aims to establish the Korean reference ranges of serum IGF-I and insulin-like growth factor binding protein-3 (IGFBP-3) and assess the relationship between IGF-I and IGFBP-3 and clinical parameters. Fasting serum was collected from healthy Korean adults at health promotion centers of five hospitals nationwide. Serum IGF-I and IGFBP-3 were measured via an immunoradiometric assay using a DSL kit (Diagnostic Systems Laboratories). Serum samples from 354 subjects (180 male, 174 female) were analyzed based on sex at 10-year intervals from 21 to 70 years. IGF-I levels were inversely correlated with age. After adjustment of age, the IGF-I/IGFBP-3 ratio was significantly negatively associated with blood pressure and free thyroxine and positively associated with weight, hemoglobin, creatinine, alanine transferase, fasting glucose, and thyroid stimulating hormone. Therefore, age- and sex-specific reference ranges of serum IGF-I and IGFBP-3 can be efficient in evaluating GH excess or deficiency in Korean population.

Background
While randomized controlled trials provide useful information about drug safety and efficacy, they do not always reflect the observed results in the real world. The prospective, observational, non-comparative trial in South Korea was designed to evaluate the efficacy and safety of pitavastatin in clinical practice in 28,343 patients.
Methods
This study was conducted in 893 facilities in Korea from April 2, 2012 to April 1, 2017. This study was designed to administer 1, 2, or 4 mg pitavastatin to patients with hyperlipidemia at the age of 20 or older for at least 8 weeks.
Results
For 126 days of mean duration of administration of pitavastatin, the % change of low density lipoprotein cholesterol indicated a dose dependent reduction: –23.4%, –29.1%, and –35.2% in the 1, 2, and 4 mg groups, respectively in patients who have not been treated with lipid lowering medications prior to study. Only 1.74% (492/28,343) of pitavastatin-treated patients experienced adverse events, of which 0.43% (123/28,343) were adverse drug reactions. Less than 1% of patients experienced the grade 2 or more toxicity (Common Terminology Criteria for Adverse Events v4.03) in alanine aminotransferase, aspartate aminotransferase, serum creatinine, and serum creatine phosphokinase. Although there were no rhabdomyolysis in 28,343 patients, 0.04% of patients had been reported pitavastatin-related musculoskeletal disorders.
Conclusion
Overall, this observational study showed that pitavastatin was well tolerated and effectively modified the lipid profile, reducing cardiovascular and cerebrovascular risk in Korean patients with hypercholesterolemia in the real world.

The leading cause of morbidity and mortality in patients with acromegaly is cardiovascular complications. Myocardial exposure to excessive growth hormone can cause ventricular hypertrophy, hypertension, arrhythmia, and diastolic dysfunction. However, congestive heart failure as a result of systolic dysfunction is observed only rarely in patients with acromegaly. Most cases of acromegaly exhibit high levels of serum insulin-like growth factor-1 (IGF-1). Acromegaly with normal IGF-1 levels is rare and difficult to diagnose. Here, we report a rare case of an acromegalic patient whose first clinical manifestation was severe congestive heart failure, despite normal IGF-1 levels. We diagnosed acromegaly using a glucose-loading growth hormone suppression test. Cardiac function and myocardial hypertrophy improved 6 months after transsphenoidal resection of a pituitary adenoma.
