COVID-19 and Thyroid diseases: How the pandemic situation affects thyroid disease patients?

Journal of the ASEAN Federation of Endocrine Societies.2020;35(2):155-157. doi:10.15605/jafes.035.02.01

Patients with thyroid diseases need special attention during this COVID-19 pandemic. There is a paucity of publications that review the effect of coronavirus infection on thyroid disease patients, such as those with hyperthyroidism, hypothyroidism, thyroid nodules and cancer. This article aims to collect reviews and statements about how the COVID-19 pandemic has affected the management of thyroid disease patients.

Journal of the ASEAN Federation of Endocrine Societies.2020;35(2):158-162. doi:10.1007/s13340-019-00393-x

Objectives. To describe the characteristics of long-standing T1DM in Thai patients and assess residual beta-cell function with status of pancreatic autoantibodies. Methodology. This is a cross-sectional study of Thai subjects with T1DM and disease duration ≥ 25 years seen at the Theptarin Hospital. Random plasma C-peptide and pancreatic auto-antibodies (Anti-GAD, Anti-IA2, and Anti-ZnT8) were measured. Patients who developed complications were compared with those who remained free of complications. Results. A total of 20 patients (males 65%, mean age 49.4±12.0 years, BMI 22.5±3.1 kg/m2, A1C 7.9±1.6%) with diabetes duration of 31.9±5.1 years were studied. Half of the participants remained free from any diabetic complications while the proportions reporting retinopathy, nephropathy, and neuropathy were 40%, 30%, and 15%, respectively. HDL cholesterol was significantly higher and triglyceride concentration significantly lower in patients who were free from diabetic nephropathy but not in those who were free from other complications. The prevalence rates of anti-GAD, anti- IA2, and anti-ZnT8 were 65%, 20%, and 10%, respectively. None of the patients who tested negative for both anti-GAD and anti-IA2 was positive for anti-ZnT8. Residual beta-cell function based on detectable random plasma C-peptide (≥ 0.1 ng/mL) and MMTT was found in only 3 patients (15%). There was no relationship between residual beta-cell function and protective effects of diabetic complications. Conclusion. Endogenous insulin secretion persists in some patients with long-standing T1DM and half of longstanding T1DM in Thai patients showed no diabetic complications. HDL cholesterol was significantly higher and triglyceride concentration significantly lower in patients who were free from diabetic nephropathy

Journal of the ASEAN Federation of Endocrine Societies.2020;35(2):163-168. doi:0.15605/jafes.035.02.03

Introduction. Vitamin B12 deficiency is more common among metformin-treated subjects although the prevalence is variable. Many factors have been associated with this. The aim of this study is to determine the prevalence of vitamin B12 deficiency and its associated factors among patients with type 2 diabetes mellitus (DM) who are on metformin. Methodology. A total of 205 patients who fit eligibility criteria were included in the study. A questionnaire was completed, and blood was drawn to study vitamin B12 levels. Vitamin B12 deficiency was defined as serum B12 level of ≤300 pg/ mL (221 pmol/L). Results. The prevalence of vitamin B12 deficiency among metformin-treated patients with type 2 DM patients was 28.3% (n=58). The median vitamin B12 level was 419 (±257) pg/mL. The non-Malay population was at a higher risk for metformin-associated vitamin B12 deficiency [adjusted odds ratio (OR) 3.86, 95% CI: 1.836 to 8.104, p<0.001]. Duration of metformin use of more than five years showed increased risk for metformin-associated vitamin B12 deficiency (adjusted OR 2.06, 95% CI: 1.003 to 4.227, p=0.049). Conclusion. Our study suggests that the prevalence of vitamin B12 deficiency among patients with type 2 diabetes mellitus on metformin in our population is substantial. This is more frequent among the non-Malay population and those who have been on metformin for more than five years.

Journal of the ASEAN Federation of Endocrine Societies.2020;35(2):169-175. doi:10.15605/jafes.035.02.04

Objectives. To determine the association between low maternal serum vitamin D and gestational diabetes mellitus (GDM) among Filipino women in St. Luke’s Medical Center, Quezon City. Methodology. A cross-sectional study involving pregnant women at outpatient clinics in a tertiary hospital in the Philippines. Simultaneous testing for fasting blood sugar, 75g oral glucose tolerance test and serum vitamin D was done. Participants were classified as GDM versus non-GDM, and normal versus low serum vitamin D. Univariate and multivariate statistics were done to determine relationship between vitamin D and GDM. Results. Of 211 included women, 198 (93.8%) had low vitamin D levels, and 56 (26.5%) had GDM. Vitamin D was significantly higher in the GDM group (21.0±8.1 vs 18.8±5.3 ng/mL, p=0.0189). The proportion of women with low vitamin D levels was significantly higher among those without GDM (96.1% vs 87.5%, OR=0.28, p=0.029]. After adjusting for age, parity, history of GDM and pre-pregnancy BMI, no significant association was observed (adjusted OR=0.66, p=0.522). No correlation was seen between vitamin D and FBS (r=0.28, p=0.095), 1-hour post-75 g OGTT (r=0.26, p=0.643), and 2-hour post-75 g OGTT (r=0.28, p=0.113). Conclusion. There was an association found between maternal serum vitamin D level and GDM in the univariate analysis, but none was evident after adjusting for possible confounders. The unanticipated high prevalence of low vitamin D levels among pregnant Filipinos needs to be verified in future studies.

Suhaimi Hussain ; Maged Elnajeh

Journal of the ASEAN Federation of Endocrine Societies.2020;35(2):176-180. doi:10.15605/jafes.035.02.05

Objective. We aim to study the prevalence and risk factors of hypovitaminosis D among healthy adolescents in Kota Bharu, Kelantan based on the most recent Paediatric Consensus guideline. Methodology. Ten public schools were selected from Kota Bharu, Kelantan. We analysed their demography (age, gender, ethnicity, income), measured their anthropometry (height, weight, BMI) and finally analysed their vitamin D and intact- Parathyroid hormone levels. Results. The prevalence of hypovitaminosis D was 16.9% among healthy teenagers with mean age of 15.9±1.39 years. Multivariate analysis showed female gender (adjusted OR, 95% CI): 23.7 (5.64, 100.3) and Chinese 0.24 (0.07, 0.84) were the significant predictors for hypovitaminosis D. Conclusion. The prevalence of healthy adolescents with hypovitaminosis D in Kota Bharu, Kelantan was 16.9% using the most recent cut off value of 30 nmol/L from the global consensus 2016. Female and Malay were the significant risk factors associated with hypovitaminosis D. Higher cut off value would result in overestimation of prevalence rate of hypovitaminosis D.

Journal of the ASEAN Federation of Endocrine Societies.2020;35(2):181-189. doi:10.15605/jafes.035.02.06

Objective. To determine the efficacy of rTMS in decreasing body mass index (BMI) versus sham stimulation among obese Filipino patients. Methodology. This was a single-center, randomized, sham-controlled, single-blind, parallel group trial. Participants were 15-65 years old with BMI ≥30 kg/m2 and weight stable for 6 weeks. Participants were randomized to receive real rTMS or sham stimulation. Each underwent 4 sessions of stimulation over 2 weeks. Anthropometrics, total caloric intake (TCI), and VAS score for appetite were taken at baseline, 2, 4, 6, and 12 weeks. Results. A total of 31 patients were randomized with 15 to the treatment and 14 to sham stimulation completing treatment, with 2 lost to follow-up. A significant decrease in BMI was noted after 4 weeks from the start of rTMS in the treatment group, (0.6±0.6, p-value=0.001), with weight change of -1.3±1.3 kg (p-value=0.009), but was no longer observed at 6 weeks onwards. No severe adverse effects were noted. Conclusion. rTMS to the DLPFC effectively decreased BMI (0.6±0.6) and weight (-1.3±1.3 kg) from baseline to 4 weeks. At 6-12 weeks after rTMS however, there was no longer a significant difference, indicating that 4 sessions of rTMS may not be enough to produce a prolonged effect on weight loss.

Journal of the ASEAN Federation of Endocrine Societies.2020;35(2):190-195. doi:0.15605/jafes.035.02.09

Objective. This study determined the relationship between plasma adiponectin level and corrected QT interval (QTc) in smokers and non-smokers. Methodology.This cross-sectional analytical study was undertaken in 30 smokers and 30 non-smokers. Plasma adiponectin level was determined by enzyme-linked immunosorbent assay (ELISA). The QT interval was measured by routine 12-lead ECG with Lead II rhythm and QTc was calculated. Results. Mean plasma adiponectin level was significantly lower in smokers (27.89±15 μg/ml) than that of non-smokers (52.13±21.57μg/ml) (p<0.001). Mean QTc interval was significantly longer in smokers than that of non-smokers (415.37±29.9 versus 395.63±26.13 ms, p<0.01). Higher risk of low adiponectin level (odds ratio [OR],8.1; 95% confidence interval [CI],1.61-40.77) and QTc interval prolongation (OR,6; 95%CI,1.17-30.73) were observed in smokers. There was weak significant negative correlation between plasma adiponectin level and QTc interval in the study population (n=60, r=-0.407, p=0.001). Moreover, low plasma adiponectin level was significantly associated with prolonged QTc interval in the study population (n=60, Fisher's exact p value<0.05). Risk of QTc interval prolongation was 4.3 times higher in subjects with low plasma adiponectin level (OR,4.27; 95% CI,1.05-17.46). Conclusion. Smokers have greater risk for low plasma adiponectin level and prolonged QTc interval. There is a relationship between plasma adiponectin level and QTc interval.

Triple synchronous tumors presenting as right nasolabial basal cell carcinoma, papillary thyroid carcinoma and prolactinoma: A rare case report

Mateo III Te ; Donnah Bless Lumanlan-Mosqueda ; Kenny Jun Demegillo

Journal of the ASEAN Federation of Endocrine Societies.2020;35(2):200-209. doi:10.15605/jafes.035.02.08

Multiple primary tumors are rare, with a published meta-analysis that shows the frequency of second primary tumor at 3-5%, and a third tumor at 0.5%. A 57-year-old female sought consultation due to a persistently bleeding right nasolabial mass. On further history and examination, she also presented with a right anterior neck mass, repeated abortions, secondary amenorrhea, and loss of libido years prior. Serum prolactin was significantly elevated and an incidental finding of a pituitary mass on head and neck CT scan was appreciated. Metastasis and syndromic familial disorder were ruled out. Bromocriptine was given and she underwent total thyroidectomy and wide excision of the right nasolabial mass which turned out to be papillary thyroid carcinoma (PTC) and basal cell carcinoma (BCC) respectively on histopathologic report. On follow up, repeat serum prolactin decreased to normal levels. After extensive literature review, this is the first documented case of triple synchronous tumors with a combination of BCC of the right nasolabial area, PTC and prolactinoma in local, national and international studies. With comprehensive work up and literature search, the diagnosis was established and ultimately the patient benefited from a multidisciplinary management.

Who were those MEN hiding behind the ulcers?

Shazatul Reza Binti Mohd Redzuan ; Yong Sy Liang

Journal of the ASEAN Federation of Endocrine Societies.2020;35(2):210-214. doi:10.15605/jafes.035.02.10

Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant disease caused by a mutation in the MEN1 gene. We present a 65-year-old man with MEN1 who has primary hyperparathyroidism, microprolactinoma, meningioma and gastrinoma. He had undergone parathyroidectomy followed by tumour excision of meningioma. The duodenal gastrinoma lesion was inoperable as it was close to the superior mesenteric artery with high surgery risk. Medical therapy with octreotide LAR had been initiated and showed good biochemical response as well as disease progression control. Chemoembolization was proposed if the duodenum lesion reduces in size on maintenance treatment with octreotide LAR. This case highlights the challenges in managing this rare condition and octreotide LAR has shown to be effective in controlling the disease progression in MEN1 with inoperable gastrinoma

Primary partial empty sella presenting with prepubertal hypogonadotropic hypogonadism

Maria Angela Matabang ; Buena Sapang

Journal of the ASEAN Federation of Endocrine Societies.2020;35(2):215-219. doi:10.15605/jafes.035.02.11

Primary partial empty sella occurs when less than 50% of an enlarged or deformed sella turcica is filled with cerebrospinal fluid in the setting of unidentified etiologic pathological conditions. Prepubertal hypogonadotropic hypogonadism presenting as its main manifestation is rare since its peak incidence commonly occurs late at 30 to 40 years of age and has a sexual predilection for female. We described a case of 20-year-old male who presented with micropenis and absent secondary sex characteristics. Work up showed cranial MRI finding of partial empty sella, low testosterone, LH, FSH, Estradiol and Beta HCG levels. Sex hormone replacement may not improve fertility for this case but may help produce and maintain virilization and prevent future complications of hypogonadotropic hypogonadism.
