TSHR Gene (rs179247) Polymorphism and Susceptibility to Autoimmune Thyroid Disease: A Systematic Review and Meta-Analysis.

BACKGRUOUND: Both Graves' disease (GD) and Hashimoto's thyroiditis (HT) are classified as autoimmune thyroid diseases (AITDs). It has been hypothesized that changes in the thyroid-stimulating hormone receptor (TSHR) gene may contribute to the development of these conditions. This study aimed to analyze the correlation between the TSHR rs179247 gene polymorphism and susceptibility to AITD. METHODS: We conducted a thorough search of the Google Scholar, Scopus, Medline, and Cochrane Library databases up until March 2, 2024, utilizing a combination of relevant keywords. This review examines data on the association between TSHR rs179247 and susceptibility to AITD. Random-effect models were employed to assess the odds ratio (OR), and the findings are presented along with their respective 95% confidence intervals (CIs). RESULTS: The meta-analysis included 12 studies. All genetic models of the TSHR rs179247 gene polymorphism were associated with an increased risk of developing GD. Specifically, the associations were observed in the dominant model (OR, 1.65; P<0.00001), recessive model (OR, 1.65; P<0.00001), as well as for the AA genotype (OR, 2.09; P<0.00001), AG genotype (OR, 1.39; P<0.00001), and A allele (OR, 1.44; P<0.00001). Further regression analysis revealed that these associations were consistent regardless of the country of origin, sample size, age, and sex distribution. However, no association was found between TSHR rs179247 and the risk of HT across all genetic models. CONCLUSION: This study suggests that the TSHR rs179247 gene polymorphism is associated with an increased risk of GD, but not with HT, and may therefore serve as a potential biomarker.

Importance of right communication with healthcare providers and patients about the new levothyroxine formulation: an expert opinion from Asia Pacific Thyroid Advisory Board.

Levothyroxine (LT4), being "narrow therapeutic index" drug, may lead to significant fluctuations in thyroid stimulating hormone (TSH) levels. Such fluctuations can result in clinically noteworthy disruptions in thyroid function and give rise to adverse clinical consequences. Consequently, regulatory standards for LT4 potency have been tightened, with the most stringent specifications requiring maintenance of potency within the range of 95-105% of the labeled dose throughout the entire shelf-life of the product. The LT4 new formulation with tightened specification adheres to these rigorous standards, demonstrating established bioequivalence to its older formulation while upholding an equivalent standard of safety and efficacy. Furthermore, the novel formulation exhibits enhanced stability and an extended shelf-life. Of paramount significance is its capacity to provide patients with accurate and consistent dosing, thereby effectively catering to their medical requirements. The primary objective of the Asia-Pacific advisory board meeting (held in June 2022 with endocrinologists, experts from India, Indonesia, Philippines, Thailand, Malaysia and Singapore) was to establish the importance of appropriate communication to HCPs, patients and other stakeholders regarding the LT4 new formulation. The aim of this brief review is to highlight the importance of communication with healthcare professionals that should focus on providing accurate information on the LT4 new formulation, emphasizing efficacy, safety, and bioequivalence with clear guidance and ensure that patients and clinicians are fully informed about any changes to medications such as LT4 to reduce the risk of unrelated adverse events being incorrectly attributed to the newer formulation.

Consensus Guidelines for Influenza Vaccination in Patients with Diabetes.

Influenza is a prevalent health issue encountered in daily practice. Patients with diabetes mellitus face a higher risk of infections, including influenza, owing to the compromised immune system associated with diabetes. This susceptibility arises from the potential of diabetes mellitus to weaken the immune system. Moreover, elevated blood glucose levels can create a conducive environment for the growth of bacteria and viruses. This consensus is formulated by a multidisciplinary team to serve as practical guidance for the administration of influenza vaccinations to patients with diabetes mellitus in daily practice.

Comparative Efficacy and Safety of Radiofrequency Ablation and Microwave Ablation in the Treatment of Benign Thyroid Nodules: A Systematic Review and Meta-Analysis.

OBJECTIVE: The current body of evidence lacks clarity regarding the comparative efficacy and safety of radiofrequency ablation (RFA) and microwave ablation (MWA) as minimally invasive treatments for benign thyroid nodules. The primary objective of this study is to clarify these concerns. MATERIALS AND METHODS: A comprehensive search was conducted using the Cochrane Library, Scopus, Europe PMC, and Medline databases until October 10th, 2023, using a combination of relevant keywords. This study incorporated literature that compared RFA and MWA for benign thyroid nodules. The primary outcome was the volume reduction ratio (VRR) from baseline to follow-up. Secondary outcomes were symptom score, cosmetic score, ablation time, major complications rate, hemorrhage, hoarseness, skin burn, cough, and sympathetic nerve injury. We used Risk of Bias in Non-randomized Studies - of Interventions (ROBINS-I) tool to assess the risk of bias in the included studies. We employed random effects models to analyze the standardized mean difference (SMD) and odds ratio for the presentation of outcomes. RESULTS: Nine studies with 2707 nodules were included. The results of our meta-analysis indicated similar efficacy between RFA and MWA in terms of VRR during the 1 (SMD 0.06; 95% confidence interval [CI]: -0.13 to 0.26; P = 0.52) and 3 (SMD 0.11; 95% CI: -0.03 to 0.25; P = 0.12) months of follow-up. VRR was significantly higher in RFA than in MWA at the 6 (SMD 0.25; 95% CI: 0.06-0.43; P = 0.008) and 12 month of follow-up (SMD 0.38; 95% CI: 0.17 to 0.59; P < 0.001). There were no significant differences between RFA and MWA in symptom scores, cosmetic scores, or the incidence of complications, including hemorrhage, hoarseness, skin burn, cough, and sympathetic nerve injury. CONCLUSION: RFA showed a higher VRR than MWA at 6 and 12-month follow-ups, with a comparable safety profile.

Near-Infrared Spectroscopy for Distinguishing Malignancy in Thyroid Nodules.

Thyroid nodules are common clinical entities, with a significant proportion being malignant. Early, accurate, and non-invasive tools to differentiate benign and malignant nodules can optimize patient management and reduce unnecessary surgery. This study aimed to evaluate the efficacy and accuracy of near-infrared spectroscopy (NIRS) in distinguishing benign from malignant thyroid nodules. A diffuse reflectance spectrum for a total of 20 thyroid nodule samples (10 samples as colloid goiter and 10 samples as thyroid cancer), were acquired in the wavelength range from 1000 to 2500 nm. Spectral data from NIRS were analyzed by means of principal component analysis (PCA), quadratic discriminant analysis (QDA), and linear discriminant analysis (LDA) to classify and differentiate thyroid nodule samples. The present study found that NIRS effectively distinguished colloid goiter and thyroid cancer using the first two principal components (PCs), explaining 90% and 10% of the variance, respectively. QDA discrimination plot displayed a clear separation between colloid goiter and thyroid cancer with minimal overlap, aligning with reported 95% accuracy. Additionally, applying LDA to seven PCs from PCA achieved a 100% accuracy rate in classifying colloid goiter and thyroid cancer from near-infrared spectral data. In conclusion, NIRS offers a promising, non-invasive complementing diagnostic tool for differentiating benign from malignant thyroid nodules with high accuracy. Future work should integrate these results into predictive model development, emphasizing external validation, alternative performance metrics, and protecting against potential overfitting translation of a machine learning model to a clinical setting.

Complete recovery after glucocorticoid replacement therapy in a case of primary adrenal insufficiency caused by adrenal tuberculosis infection.

Summary: Symptoms of primary adrenal insufficiency (PAI) are commonly nonspecific, causing the disease to be misdiagnosed or often delayed, and patients may present to the hospital with a life-threatening crisis. Previous case reports have documented that patients in this condition often require lifelong glucocorticoid replacement therapy. This study aimed to present a noteworthy outcome of PAI caused by adrenal tuberculosis infection, demonstrating complete recovery after six months of glucocorticoid replacement therapy. A 38-year-old Indonesian man presented to the endocrinology clinic in a tertiary hospital with a chief complaint of epigastric pain. The patient experienced nausea, vomiting, loss of consciousness, weight loss, excessive sweat, decreased appetite, weakness, and dizziness in the past 2 weeks. Laboratory examinations revealed hyponatremia, elevated adrenocorticotropic hormone, and suppressed morning plasma cortisol level. A non-contrast-enhanced abdominal MRI showed unilateral right-side adrenal enlargement and calcification. The patient's Mantoux test was positive. Corticosteroids and anti-tuberculosis therapy were administered. After 6 months, hydrocortisone was discontinued due to the patient's good clinical condition and normal morning plasma cortisol levels. After a 1-year follow-up, the patient remained asymptomatic with normal cortisol levels. We hypothesized several reasons for this unique outcome: (i) the patient was relatively young compared to previous cases, suggesting an adequate immune system may play a role; (ii) despite a 1-month delay in diagnosis and treatment, the absence of skin hyperpigmentation suggested an acute presentation, potentially contributing to the favorable outcome; and (iii) the absence of comorbidities potentially positively impacted the patient's outcome. Learning points: Symptoms of adrenal insufficiency are often nonspecific and may only become apparent once significant damage has occurred to the adrenal gland. Clinical adjustments and a comprehensive understanding of epidemiological knowledge are necessary for diagnosing patients with endocrine diseases in limited-resource settings. Complete recovery in primary adrenal insufficiency caused by tuberculosis infection might be due to younger age, acute presentation, and absence of comorbidities.

Effects of mobile phone electromagnetic radiation on thyroid glands and hormones in Rattus norvegicus brain: An analysis of thyroid function, reactive oxygen species, and monocarboxylate transporter 8.

The aim of this study was to investigate the effects of mobile phone electromagnetic radiation (MP-EMR) on the thyroid glands and hormones in Rattus norvegicus brain in term of thyroid function, reactive oxygen species (ROS), and monocarboxylate transporter 8 (MCT8) concentration. Forty rats were divided into different groups: control (without EMR exposure), EMR1 (120-min/day exposure), EMR2 (150-min), and EMR3 (180-min). The levels of serum thyroid stimulating hormone (TSH), thyroxine (T4), and malondialdehyde (MDA) and brain and MCT8 were measured using enzyme-linked immunosorbent assay. One-way analysis of variance followed by the Duncan test was used to analyze the data. Our data indicated that the levels of serum TSH and T4 in all the EMR groups were lower significant postexposure compared to the control with P < 0.01 (EMR1 and EMR2) and P < 0.001 (EMR3), suggesting hypothyroidism due to MP-EMR exposure. Increased MDA and decreased MCT8 levels were also observed following the intervention; however, the changes in both concentrations were notably significant after being subjected to 150-min and 180-min of exposure. In conclusion, a significant reduction in TSH, T4, and MCT8 levels indicated thyroid dysfunction due to MP-EMR exposure.

Complexity of diagnosis and management of a giant thyroid nodule: A case report and a concise literature.

It is crucial for doctors to decide whether a thyroid nodule is benign or malignant when a patient presents with one, as it will significantly impact how the patient is managed in the future. However, it is not as straightforward to determine between the two; even a physical examination, thyroid function test, ultrasonography, and biopsy have been well performed. It can be more stressful if a patient has an increased risk of malignancy, such as age (below 20- and above 60-year-old), solid nodule, rapid growth, hoarseness, lymphadenopathy, and microcalcifications on the ultrasonography. The aim of this case was to present the management of a giant thyroid nodule with malignancy presentation and a benign biopsy finding. A 41-year-old male complained of a palpable neck mass, hoarseness, and dysphagia. The thyroid function test was normal. Ultrasonography revealed suspicion of malignancy with category 4 of American College of Radiology-Thyroid Imaging Reporting and Data System (ACR-TIRADS). The biopsy revealed follicular neoplasm, and was classified as Bethesda IV. The patient underwent a total thyroidectomy due to the large tumor size and symptoms. Histopathological findings post-surgery revealed a follicular thyroid adenoma. This case highlights a complex diagnosis and management of follicular thyroid neoplasm due to their potential for both benign and malignant. Comprehensive pre- and post-operative care is essential to determine the nature of nodules. Post-operative follow-up care might improve the patient's outcome and prevent complications.

Normal intellectual ability and hyperprolactinemia as unique clinical manifestations of congenital hypothyroidism: A case report and review of hypotheses.

Congenital hypothyroidism is the deficiency of thyroid hormone in infants and hyperprolactinemia is frequently observed. Previously reported cases typically involve intellectual disability, highlighting this particular unique case report to the first reported patient demonstrating normal intellectual ability despite experiencing growth and gonad dysfunction. This study aims to present a case and review medical hypotheses related to the patient's condition. A 19-year-old female presented with a chief complaint of irregular menstruation for up to 40 days or not occurring at all. The patient experienced the first menstruation at the age of 16 years old. The patient's height was 133 cm, body weight 40 kg, and body mass index 22.61 kg/m2; other family members were normal. Physical examination showed no abnormalities, and laboratory examination showed suppressed serum free T4 (FT4) level (6.41 pmol/L), elevated thyroid stimulating hormone (TSH) level (333.700 µIU/mL), and elevated prolactin hormone level (32.03 ng/mL). Ultrasound of the thyroid gland found hypoplasia of the left and right thyroid glands. The patient was a college student enrolled in a public national university and had never complained about academic performance throughout the patient's education. The patient was diagnosed with congenital hypothyroidism and hyperprolactinemia. The patient was administered up to 100 µg daily of oral levothyroxine, which improved the patient's menstrual cycles. The patient's delayed diagnosis may be attributed to central congenital hypothyroidism being underdiagnosed. We hypothesized that thyroid-releasing hormone receptor (TRHR) gene mutation might contribute to the underlying cause of hyperprolactinemia and normal intellectual ability of the patient. Further study on the significance of TRHR gene mutations in congenital hypothyroidism is required to improve diagnosis and treatment.

Comparative analysis of accuracy between fine-needle aspiration biopsy and postoperative histopathology for detecting large thyroid nodules: A retrospective observational study.

To avoid unnecessary surgeries, ultrasound-guided fine-needle aspiration biopsy (FNAB) is an effective and reliable procedure for the preoperative evaluation of thyroid nodules. However, there have been only a limited number of studies exploring the ability of preoperative FNAB to distinguish malignancy compared to postoperative histopathology in thyroid nodules larger than 4 cm. The aim of this study was to investigate the diagnostic accuracy of FNAB compared to postoperative histopathology in distinguishing malignancy in thyroid nodules larger than 4 cm. A single-center retrospective observational study was conducted at Dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia, between January 2014 and December 2018. The sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were calculated. A total of 83 patients were included in the study. The results showed that preoperative FNAB may have the ability to distinguish malignancy compared to postoperative histopathology. The sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were 42.85%, 98.38%, 90.00%, 83.56%, and 84.33%, respectively. These data suggested that ultrasound-guided preoperative FNAB is a reliable diagnostic tool in the preoperative evaluation of thyroid nodules larger than 4 cm, but it has limited capability in distinguishing malignancies. In conclusion, although FNAB may be useful in reducing unnecessary surgeries, histopathology remains the preferred method for confirming malignancy in thyroid nodules.

Severe hypocalcemia as a cause of transient ischemic attack? A debatable case and evidence from literature.

Hypocalcemia and transient ischemic attack (TIA) are different medical disorders; however, limited evidence suggests a possible link between the two. The underlying pathomechanisms by which hypocalcemia may cause cerebrovascular damage are difficult to comprehend. The aim of the study was to present an individual experiencing TIA that possibly due to severe hypocalcemia that associated with hypoparathyroidism after total thyroidectomy; and to explore the available evidence of its cause-effect relationship through available literature. A 68-year-old man presented to Dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia with complaints of weakness, especially in the right limbs that had worsened in the last week. The patient experienced unconsciousness for an hour before the admission; disorientation and anterograde amnesia over the time of recovering of consciousness. Other complaints included frequent muscle cramps, numbness in both arms and legs, dizziness, swallowing difficulty, nausea, and vomiting. The patient had a history of total thyroidectomy for a large struma diffuse 18 years ago and was prescribed several medications. However, the patient was overwhelmed by forgetfulness which had become more frequent in recent months resulting in medication nonadherence. The vital sign was stable and Chovsteck's sign was positive. The Montreal Cognitive Assessment (MoCA) revealed impairment in the visuospatial/executive component and delayed memory. Laboratory tests revealed severe hypocalcemia, altered thyroid function, hypomagnesemia, elevated D-dimer and fibrinogen, and vitamin D deficiency. TIA and severe hypocalcemia were proposed as the diagnosis. Prompt initiation of appropriate treatment, including calcium supplementation, anticoagulation, and neuroprotective agents, led to significant clinical improvement. Evidence from available literature suggests that there is a possible link between severe hypocalcemia and TIA that occurred in this patient. However, more studies are warrant to establish this cause-effect relationship.

Expert Opinion on Diabetes Management Challenges and Role of Basal Insulin/GLP-1 RA Fixed-Ratio Combination in People with Type 2 Diabetes from Indonesia.

Indonesia is struggling with a rapidly growing burden of diabetes due to rapid socioeconomic transition. People with type 2 diabetes mellitus (T2DM) need appropriate treatment strategies to maintain glycemic control. New modalities with simplicity, such as fixed-ratio combination of basal insulin and glucagon-like peptide-1 receptor agonist (GLP-1 RA), further referred to as FRC, have proven to be an effective and practical therapeutic approach that may address this issue. In January 2021, a scientific expert meeting was held with the participation of endocrinologists from Indonesia to provide expert opinions regarding the optimal practical use of the FRC basal insulin/GLP1-RA. Topics discussed in the meeting included the challenges in diabetes management, clinical inertia with insulin therapy, local and international guideline positioning, initiation, titration, and switching of basal insulin and GLP-1 RA, including FRC, and the management of T2DM.

Indonesia DIA-RAMADAN Study: A Real-life, Prospective and Observational of Gliclazide MR in Type-2 Diabetes Patients During Ramadan Fasting.

BACKGROUND: Sulfonylureas (SUs) have been widely used in many countries for T2DM treatment. Gliclazide is one of the SUs with the lowest risk of hypoglycemia; however, the safety and effectiveness of gliclazide MR during Ramadan has not yet been reported in Indonesia. This study aimed to assess safety, efficacy, and tolerability of gliclazide modified release (MR) during Ramadan fasting. METHODS: The study was a part of DIA-RAMADAN study, a prospective observational study with subjects of T2DM patients aged >18 years, who had either controlled or sub-optimally controlled blood glucose level, performed Ramadan fasting. Subjects had been treated with gliclazide MR for at least 90 days prior the study, and were examined for their body mass index (BMI), fasting plasma glucose (FPG) and HbA1c levels 6 to 8 weeks before Ramadan (V0) and 4 to 6 weeks after the end of Ramadan (V1). RESULTS: Out of 198 subjects participating in the study, there were only two subjects (1.0%) who reported symptomatic HEs (either confirmed or not confirmed) and no severe HEs had been reported. There were no significant changes in HbA1c and FPG levels (p>0.05). Interestingly, there was a reduction of bodyweight (-0.4kg) from pre- to post-Ramadan (p < 0.001). Almost no subjects reported discontinuation of gliclazide MR throughout the entire study; however, there was one subject who reported a change of diabetic treatment into diet only. CONCLUSION: gliclazide MR is safe, well tolerated and can maintain glycemic control effectively for Indonesian patients with T2DM who perform Ramadan fasting.

Comparative performance of ELISA and dot blot assay for TSH-receptor antibody detection in Graves' disease.

BACKGROUND: Graves' disease (GD) is an autoimmune disease, and it accounts for major cases of hyperthyroidism. Antibody against thyroid-stimulating hormone receptor/TSHR (TRAb) is responsible for hyperthyroidism and is considered as a diagnostic marker for GD. Therefore, we developed a recombinant protein of human TSHR-169 (hTSHR-169), which was specifically recognized TRAb in the serum of GD patients and then compare the diagnostic performance between ELISA and dot blot of TRAb tests for their ability to diagnose GD. METHODS: 20 GD patients and 20 healthy individuals from the Indonesian population were enrolled. TRAb concentration and density were quantified. Comparative analysis was performed using receiver-operating curve (ROC) analysis. RESULTS: For dot blot assay, the minimum concentration to detect TRAb requiring 100 ng of antigen with antiserum diluted at 1:60. For diagnosing GD, the ELISA yielded a higher AUC compared with the dot blot assay (0.95 and 0.85, respectively). Using the recommended cutoff values, the efficiency of both assays was examined by comparing the specificity and sensitivity of the assays to the clinical diagnosis. The ELISA showed 80% and 95%, while the dot blot assay showed 70% and 95% sensitivity and specificity, respectively. CONCLUSION: Although the dot blot assay exhibited lower performance than the ELISA method, the dot blot assay is a simple and rapid diagnostic assay that is suitable for diagnosing GD in rural areas, in which healthcare facilities sometimes are not accessible.

Individualizing Time-in-Range Goals in Management of Diabetes Mellitus and Role of Insulin: Clinical Insights From a Multinational Panel.

Diabetes mellitus is a global health concern associated with significant morbidity and mortality. Inadequate control of diabetes leads to chronic complications and higher mortality rates, which emphasizes the importance of achieving glycemic targets. Although glycated hemoglobin (HbA1c) is the gold standard for measuring glycemic control, it has several limitations. Therefore, in recent years, along with the emergence of continuous glucose monitoring (CGM) technology, glycemic control modalities have moved beyond HbA1c. They encompass modern glucometrics, such as glycemic variability (GV) and time-in-range (TIR). The key advantage of these newer metrics over HbA1c is that they allow personalized diabetes management with person-centric glycemic control. Basal insulin analogues, especially second-generation basal insulins with properties such as longer duration of action and low risk of hypoglycemia, have demonstrated clinical benefits by reducing GV and improving TIR. Therefore, for more effective and accurate diabetes management, the development of an integrated approach with second-generation basal insulin and glucometrics involving GV and TIR is the need of the hour. With this objective, a multinational group of endocrinologists and diabetologists reviewed the existing recommendations on TIR, provided their clinical insights into the individualization of TIR targets, and elucidated on the role of the second-generation basal insulin analogues in addressing TIR.

Dietary knowledge, preferences and behaviors in Ramadan among Muslim patients with type 2 diabetes.

AIMS: To explore the association between dietary knowledge, attitude, and practices during Ramadan among Muslim patients with type 2 diabetes. METHODS: Recruited after Ramadan from public clinics and a hospital in Banda Aceh, Indonesia, 401 outpatients recalled their food consumption frequencies of high-fiber food, deep-fried food, and high-sugar dessert, and relevant knowledge and attitudes. Multivariable logistic regression models were applied to examine the research questions. RESULTS: Vegetable consumption and preference were both high among the patients. However, only 4.5% knew that brown rice is rich in fiber, and 19% agreed that whole-grain foods were accessible. Deep-fried food consumption and its availability at home was common, even though the majority considered it should be avoided. Patients with a lower preference for deep-fried foods were less likely to consume deep-fried foods during Ramadan (OR = 0.239, 95% CI = 0.109-0.523, p = 0.001). Knowledge of the glycemic index's health implication was associated with more high-fiber foods consumption (OR = 2.733, 95% CI = 1.179-6.332, p = 0.019). Yet, knowing the potential risk of added sugar on blood glucose level was associated with high-sugar dessert consumption (OR = 2.997, 95% CI = 1.482-6.060, p = 0.002). CONCLUSION: The patients' low consumption of whole-grain food and common comsumption of deep-fried food during Ramadan would be the first priority to be improved. Along with dietary knowledge and attitude, food environment could be an important factor that influences patients' dietary behaviors.

Using peer education to improve diabetes management and outcomes in a low-income setting: a randomized controlled trial.

BACKGROUND: Diabetes is an important health burden in Indonesia. However, diabetes management and treatment remain poor, with most people with diabetes in Indonesia not achieving the recommended blood glucose levels. Peer education may have particular potential in low-income settings in complementing diabetes care without being a large additional strain on the health system. METHODS/DESIGN: This cluster randomized controlled trial aims to identify the effect of the implementation of peer education for patients with type 2 diabetes on diabetes-related outcomes in Aceh, Indonesia, which will complement the diabetes treatment provided at primary-care health posts (puskesmas). Altogether, 29 puskesmas were recruited in Banda Aceh and Aceh Besar, each of which was randomly assigned to either the control or the intervention group. Then, 534 people with diabetes were identified and recruited through their respective puskesmas. The intervention consists of up to two peer education groups per puskesmas, which are led by previously trained people with diabetes. Peer education sessions are held every month for 18 months, with follow-up data being collected 9 and 18 months after the first peer education session. The main objective is to improve diabetes management and the health behavior of participants receiving peer education to reduce their average blood glucose levels as measured by glycated hemoglobin (HbA1c) levels. Secondary outcomes are the effects of peer education on lipid levels, waist circumference, blood pressure, quality of life, treatment adherence, diabetes knowledge, physical activity, and dietary diversity. Data sources for the measurement of outcomes include patient and health facility surveys and biomarker measurements. An economic evaluation will be conducted to assess the cost-effectiveness of the intervention. DISCUSSION: This trial will contribute to the evidence on the effectiveness and cost-effectiveness of peer education in improving diabetes management in a low-income setting in Indonesia and in other comparable contexts. TRIAL REGISTRATION: ISRCTN registry, ISRCTN68253014 . Registered on 18 February 2019.

The effects of celery leaf (apium graveolens L.) treatment on blood glucose and insulin levels in elderly pre-diabetics.

OBJECTIVES: To analyze the effect of celery leaf extract on blood glucose and plasma insulin levels in elderly pre-diabetics. Methods: This study was conducted between March and November 2014 at the Faculty of Medicine, Syiah Kuala University, Banda Aceh, Indonesia. A quasi-experimental pretest-posttest with a control group was conducted with elderly pre-diabetic volunteers. The subjects included 16 elderly pre-diabetics older than 60 (6 males and 10 females). The subjects were randomly divided into 2 groups: a control group (placebo-treated) and a treatment group (celery-treated). The treatment consisted of celery leaf extract capsules at the dose of 250 mg, 3 times per day (morning, afternoon and evening), 30 minutes before a meal, for 12 days. Data analysis was performed using the t-test (p less than 0.05). Results: There was a significant decrease in pre-prandial plasma glucose levels (p=0.01) and post-prandial plasma glucose levels (p=0.00), but no significant increase in plasma insulin levels (p=0.15) after celery leaf treatment in elderly pre-diabetics. Conclusion: Celery was effective at reducing blood glucose levels, but there was a lack of association between blood glucose levels and plasma insulin levels in elderly pre-diabetics.
