Background
Thyroid-stimulating hormone (TSH)-secreting pituitary neuroendocrine tumor (TSH PitNET) is a rare subtype of PitNET. We investigated the comprehensive characteristics and outcomes of TSH PitNET cases from a single medical center. Also, we compared diagnostic methods to determine which showed superior sensitivity.
Methods
A total of 17 patients diagnosed with TSH PitNET after surgery between 2002 and 2022 in Samsung Medical Center was retrospectively reviewed. Data on comprehensive characteristics and treatment outcomes were collected. The sensitivities of diagnostic methods were compared.
Results
Seven were male (41%), and the median age at diagnosis was 42 years (range, 21 to 65); the median follow-up duration was 37.4 months. The most common (59%) initial presentation was hyperthyroidism-related symptoms. Hormonal co-secretion was present in four (23%) patients. Elevated serum alpha-subunit (α-SU) showed the greatest diagnostic sensitivity (91%), followed by blunted response at thyrotropin-releasing hormone (TRH) stimulation (80%) and elevated sex hormone binding globulin (63%). Fourteen (82%) patients had macroadenoma, and a specimen of one patient with heavy calcification was negative for TSH. Among 15 patients who were followed up for more than 6 months, 10 (67%) achieved hormonal and structural remission within 6 months postoperatively. A case of growth hormone (GH)/TSH/prolactin (PRL) co-secreting mixed gangliocytoma-pituitary adenoma (MGPA) was discovered.
Conclusion
The majority of the TSH PitNET cases was macroadenoma, and 23% showed hormone co-secretion. A rare case of GH/TSH/PRL co-secreting MGPA was discovered. Serum α-SU and TRH stimulation tests showed great diagnostic sensitivity. Careful consideration is needed in diagnosing TSH PitNET. Achieving remission requires complete tumor resection. In case of nonremission, radiotherapy or medical therapy can improve the long-term remission rate.

Background
Pheochromocytoma and paraganglioma (PPGL) is diagnosed through biochemical confirmation of excessive catecholamines in urine and plasma. Recent technological developments have allowed us to measure urinary free metanephrines; however, the diagnostic accuracy of these new methods and the diagnostic cutoff values have not been evaluated.
Methods
This is a retrospective study of 595 subjects, including 71 PPGL cases and 524 controls. PPGL was based on pathological confirmation. Subjects with no evidence of PPGL over 2 years were included in the control group.
Results
Urinary free metanephrines yielded similar area under the curve (AUC) to urinary fractionated metanephrines and plasma free metanephrines. However, urinary free normetanephrine yielded a better AUC than did urinary fractionated normetanephrine. The optimal cutoff for urinary free metanephrine and normetanephrine corrected for urinary creatinine yielded 97.2% sensitivity and 98.1% specificity.
Conclusion
Urinary free metanephrines are a reliable method for diagnosing PPGL in Asian populations compared with existing biochemical methods.

Background
Type 2 diabetes and cardiovascular disease (CVD) are the most important sequelae of obesity and the leading cause of death. We evaluated the association between body mass index (BMI) and the risk of incident type 2 diabetes, CVD, and all-cause mortality in a prospective study of a Korean population.
Methods
The shapes of the associations were modeled by restricted cubic splines regression analysis. After categorizing all subjects (n=8,900) into octiles based on their BMI levels, we estimated the hazard ratio (HR) for the association of categorized BMI levels with the risk of incident CVD and type 2 diabetes using a Cox’s proportional hazard analysis.
Results
The mean age of participants was 52 years and 48% were men. Of the subjects at baseline, 39.0% of men and 45.6% of women were classified as obese (BMI ≥25 kg/m2). Over a mean follow-up of 8.1 years, CVD events occurred in 509 participants; 436 died; and 1,258 subjects developed type 2 diabetes. The increased risk of incident diabetes began to be significant at BMI 23 to 24 kg/m2 in both sexes (HR, 1.8). For CVD events, the risk began to increase significantly at BMI 26 to 28 kg/m2 (HR, 1.6). We found a reverse J-shaped relationship between BMI and all-cause mortality, with an increased risk among individuals with BMI values in lower range (BMI <21 kg/m2).
Conclusion
These results suggest that the BMI cut-off points for observed risk were varied depending on the diseases and that the BMI classification of obesity need to be revised to reflect differential risk of obesity-related diseases.

Background

Incretin hormone levels as a predictor of type 2 diabetes mellitus have not been fully investigated. Therefore, we measured incretin hormone levels to examine the relationship between circulating incretin hormones, diabetes, and future diabetes development in this study.

Methods

A nested case-control study was conducted in a Korean cohort. The study included the following two groups: the control group (n=149), the incident diabetes group (n=65). Fasting total glucagon-like peptide-1 (GLP-1) and total glucose-dependent insulinotropic peptide (GIP) levels were measured and compared between these groups.

Results

Fasting total GIP levels were higher in the incident diabetes group than in the control group (32.64±22.68 pmol/L vs. 25.54±18.37 pmol/L, P=0.034). There was no statistically significant difference in fasting total GLP-1 levels between groups (1.14±1.43 pmol/L vs. 1.39±2.13 pmol/L, P=0.199). In multivariate analysis, fasting total GIP levels were associated with an increased risk of diabetes (odds ratio, 1.005; P=0.012) independent of other risk factors.

Conclusion

Fasting total GIP levels may be a risk factor for the development of type 2 diabetes mellitus. This association persisted even after adjusting for other metabolic parameters such as elevated fasting glucose, hemoglobin A1c, and obesity in the pre-diabetic period.

AbstractAbstract PDFPubReader   

Cushing's disease (CD) is a rare disorder characterized by the overproduction of adrenocorticotropic hormone due to a pituitary adenoma that ultimately stimulates excessive cortisol secretion from the adrenal glands. Prior to the detection of pituitary adenomas, various clinical signs of CD such as central obesity, moon face, hirsutism, and facial plethora are usually already present. Uncontrolled hypercortisolism is associated with metabolic, cardiovascular, and psychological disorders that result in increased mortality. Hence, the early detection and treatment of CD are not only important but mandatory. Because its clinical manifestations vary from patient to patient and are common in other obesity-related conditions, the precise diagnosis of CD can be problematic. Thus, the present set of guidelines was compiled by Korean experts in this field to assist clinicians with the screening, diagnoses, and treatment of patients with CD using currently available tests and treatment modalities.

Background

Primary hypophysitis causes varying degrees of endocrine dysfunction and mass effect. The natural course and best treatment have not been well established.

Methods

Medical records of 22 patients who had been diagnosed with primary hypophysitis between January 2001 and March 2013 were retrospectively reviewed. Based on the anatomical location, we classified the cases as adenohypophysitis (AH), infundibuloneurohypophysitis (INH), and panhypophysitis (PH). Clinical presentation, endocrine function, pathologic findings, magnetic resonance imaging findings, and treatment courses were reviewed.

Results

Among 22 patients with primary hypophysitis, 81.8% (18/22) had involvement of the posterior pituitary lobe. Two patients of the AH (2/3, 66.6%) and three patients of the PH (3/10, 30%) groups initially underwent surgical mass reduction. Five patients, including three of the PH (3/10, 33.3%) group and one from each of the AH (1/3, 33.3%) and INH (1/9, 11.1%) groups, initially received high-dose glucocorticoid treatment. Nearly all of the patients treated with surgery or high-dose steroid treatment (9/11, 82%) required continuous hormone replacement during the follow-up period. Twelve patients received no treatment for mass reduction due to the absence of acute symptoms and signs related to a compressive mass effect. Most of them (11/12, 92%) did not show disease progression, and three patients recovered partially from hormone deficiency.

Conclusion

Deficits of the posterior pituitary were the most common features in our cases of primary hypophysitis. Pituitary endocrine defects responded less favorably to glucocorticoid treatment and surgery. In the absence of symptoms related to mass effect and with the mild defect of endocrine function, it may not require treatment to reduce mass except hormone replacement.

Background

Serum albumin has been suggested to be associated with insulin resistance. We evaluated the association between serum albumin concentration and insulin resistance. We also investigated whether serum albumin level has an independent effect on the development of diabetes.

Methods

In our study, 9,029 subjects without diabetes, who underwent comprehensive health check-ups annually for 5 years, were categorized into tertiles based on their serum albumin levels at baseline. The odds ratio (OR) for the prevalence of insulin resistance, defined as the top quartile of homeostasis model assessment of insulin resistance and the presence of impaired fasting glucose and nonalcoholic fatty liver disease, was evaluated cross-sectionally. Also, the hazard ratio (HR) for incident diabetes was estimated longitudinally, according to the baseline albumin tertiles using Cox proportional hazard analysis respectively.

Results

From the lowest to the highest tertile of albumin, the multivariable-adjusted ORs of insulin resistance increased significantly in both men and women. During the mean follow-up period of nearly 4 years, 556 (6.1%) subjects progressed to diabetes. The multivariable-adjusted HR (95% confidence interval [CI]) of diabetes in men were 1, 1.09 (95% CI, 0.86 to 1.40), and 1.10 (95% CI, 0.86 to 1.41), respectively, from the lowest to the highest tertiles of baseline albumin. Corresponding values for women were 1, 1.21 (95% CI, 0.66 to 2.21), and 1.06 (95% CI, 0.56 to 2.02), respectively.

Conclusion

Our study showed that increased serum albumin level was associated with insulin resistance. However, serum albumin did not have an independent effect on the development of diabetes.

AbstractAbstract PDF
We report here on a 34-year-old Korean woman with active acromegaly and who received Octreotide-LAR(R) for 12 months following transsphenoidal pituitary surgery. During Octreotide-LAR(R) treatment, the clinical improvement was paralleled with the decrease of the growth hormone levels to 1.1 ng/mL and the insulin-like growth factor-I (IGF-I) levels to 345.5 ng/mL. Octreotide-LAR(R) was discontinued when the patient was found to be at the 12th week of pregnancy. During pregnancy, the patient experienced clinical well-being and she maintained her IGF-I levels within the normal range for her age-matched despite discontinuation of Octreotide-LAR(R) treatment at early gestation. She delivered a full-term healthy male infant. The serum IGF-I levels of the patient increased progressively increased after delivery. This report describes a successful pregnancy in an acromegalic woman who was exposed to Octreotide-LAR(R) during the early gestational period. She and who showed an unexpected pattern of persistently normal IGF-I levels through the pregnancy despite discontinuation of Octreotide-LAR(R) therapy.

AbstractAbstract PDF
BACKGROUND
Studies on the clinicopathological characteristics and prognostic factors of medullary thyroid carcinoma (MTC) in Korea are very rare. METHODS: We enrolled 56 MTC patients who underwent surgery at Samsung Medical Center from 1995 to 2006. We analyzed their gender, age at diagnosis, the pathologic findings, the TNM stage, the association with multiple endocrine neoplasia (MEN), RET protooncogene mutation and the, serum basal calcitonin levels before and after the surgery. We investigated the overall survival and the prognostic factors. RESULTS: The mean age at diagnosis was 46 years and the male/female ratio was 1:2.7. Fine needle aspiration cytology detected 61% of the MTC. The mean tumor size was 2.6 cm (range: 0.2-9.0 cm). Fifty-two percent of patients had the TNM stage more than III at the time of diagnosis. Distant metastasis was found in 5.3% (3/56) of the patients, either at the time of diagnosis or during the follow-up period. Hereditary MTC comprised of 23% of the patients and the disease developed at a younger age (38 years vs. 48 years, respectively, P < 0.05) with more bilaterality. RET protooncogene mutations were found in 27% (9/33) of the patients and most of them were in codon 634. After the primary surgery, the serum basal calcitonin levels were persistently elevated over 13 ng/L in 49% of the patients. The overall 5-year survival rate was 95.5%. Tumor size and distant metastasis were the significant prognostic factors for survival by univariate analysis (P < 0.05). CONCLUSION: There were no significant differences in the clinicopathological characteristics of MTC and survival in Korea compared to those of the Western countries.

AbstractAbstract PDF
BACKGROUND
New onset diabetes is a major complication after kidney transplantation. However, the natural course of posttransplantation diabetes mellitus (PTDM) remains unclear. The aim of this study was to demonstrate the detailed natural courses of PTDM according to the onset and persistency of hyperglycemia, and to investigate risk factors for development of different courses of PTDM in renal allograft recipients. METHODS: A total of 77 renal allograft recipients without previously known diabetes were enrolled and performed a serial 75 g oral glucose tolerance test at 0, 1, and 7 years after kidney transplantation. Patients were classified according to the onset and persistency of PTDM: early PTMD (E-PTDM), late PTDM (L-PTDM), persistent PTDM (P-PTDM), transient PTMD (T-PTDM), and non-PTDN (N-PTDM). RESULTS: The incidence of each group was as follows: E-PTDM, 39%; L-PTDM, 11.7%; P-PTDM, 23.4% T-PTDM, 15.6%; N-PTDM, 49.3%. Tacrolimus and female gender were associated with the development of E-PTDM. Among E-PTDM, age at transplantation was a high risk factor for the development of P-PTDM. Higher BMI at year1 was associated with the development of L-PTDM. CONCLUSION: Different risk factors were associated with various natural courses of PTDM. Since old age and female gender are not modifiable risk factors, it may be important to modify immunosuppressive therapy regimens for the prevention of E-PTDM and control of body weight for L-PTDM.

AbstractAbstract PDF
BACKGROUND
The aim of this study was to examine the association between the common polymorphisms of the adiponectin gene(ACDC) and the intima-media thickness(IMT) of the common carotid arteries in type 2 diabetic patients. METHODS: The B mode ultrasound examination of carotid artery was performed on 133 type 2 diabetic patients. The carotid IMT was calculated using the Intimascope computer program. The SNP45 and SNP276 of the ACDC were examined. RESULTS: There was no significant difference in the carotid IMT among the SNP45 genotypes(0.66+/-0.18mm for TT, 0.71+/-0.12mm for TG and 0.64+/-0.15mm for GG, P=NS). Subjects carrying the SNP276 GG genotype had a markedly lower serum adiponectin concentration than those carrying the TT genotype(3.35+/-2.00microgram/mL vs. 4.98+/-2.24microgram/mL, P=0.029) The carotid IMT was significantly higher in patients with the SNP276 GG genotype than those with the TT genotype (0.70+/-0.17mm vs. 0.59+/-0.13mm, P=0.032). Patients with the +45GG/+276GG genotype combination showed significantly higher mean carotid IMT than the other genotype combinations(0.78+/-0.09mm vs. 0.71+/-0.15mm, P=0.013) CONCLUSIONS: These results suggest that the adiponectin gene, SNP276 is associated with the carotid IMT in type 2 diabetic patients. Further studies are will be needed to confirm these genotypephenotype associations.

AbstractAbstract PDF
In this report, a 70-year-old female patient was detected with laboratory findings of hypercalcemia. The most common causes of hypercalcemia are primary hyperparathyroidism and malignant disease. Her laboratory tests did not show any evidence for neither primary hyperparathyroidism nor malignant diseases. Thus, granulomatous disease was suspected as the cause of the hypercalcemia. Liver MRI (magnetic resonance image) was performed on the subject, which suggested the presence of hepatic tuberculosis and sarcoidosis. Because the chest x-ray did not show a definite tuberculous lesion, we performed a laparoscopic liver biopsy for a final diagnosis. Findings from the biopsy specimen showed typical tuberculosis. After treatment with tuberculosis medication, hypercalcemia of the subject was resolved. Hypercalcemia is a well recognized as a possible complication of active pulmonary tuberculosis. But one should consider hepatic tuberculosis without pulmonary tuberculosis as a cause of hypercalcemia.
