Genetic variants associated with poor responsiveness to sulfonylureas in Filipinos with type 2 diabetes mellitus / Journal of the ASEAN Federation of Endocrine Societies

Introduction@# Sulfonylureas (SUs) are commonly used drugs for type 2 diabetes mellitus (T2DM) in the Philippines. This study aimed to associate genetic variants with poor response to gliclazide and glimepiride among Filipinos.@*Methodology@#Two independent, dichotomous longitudinal substudies enrolled 139 and 113 participants in the gliclazide and glimepiride substudies, respectively. DNA from blood samples underwent customized genotyping for candidate genes using microarray. Allelic and genotypic features and clinical associations were determined using exact statistical methods.@*Results@#Three months after sulfonylurea monotherapy, 18 (13%) were found to be poorly responsive to gliclazide, while 7 (6%) had poor response to glimepiride. Seven genetic variants were nominally associated (p<0.05) with poor gliclazide response, while three variants were nominally associated with poor glimepiride response. For gliclazide response, carboxypeptidase-associated variants (rs319952 and rs393994 of AGBL4 and rs2229437 of PRCP) had the highest genotypic association; other variants include rs9806699, rs7119, rs6465084 and rs1234315. For glimepiride response, 2 variants were nominally associated: CLCN6-NPPA-MTHFR gene cluster – rs5063 and rs17367504 – and rs2299267 from the PON2 loci.@*Conclusion@#Genetic variants were found to have a nominal association with sulfonylurea response among Filipinos. These findings can guide for future study directions on pharmacotherapeutic applications for sulfonylurea treatment in this population.

AFES A.S.-O.N.E.: ASEAN survey of needs in Endocrinologyin the time of the COVID-19 pandemic / Journal of the ASEAN Federation of Endocrine Societies

Objectives@#The COVID-19 pandemic has made a major impact on hospital services globally, including the care of persons with diabetes and endocrine disorders. The aim of this study is to describe the epidemiology of COVID-19 in the ASEAN Federation of Endocrine Societies (AFES) member countries; to describe challenges, changes and opportunities in caring for patients with endocrine diseases, as well as in fellowship training programs, and endocrine-related research in the AFES countries.@*Methodology@#The AFES ASEAN Survey Of Needs in Endocrinology (AFES A.S.-O.N.E.) was an open-ended questionnaire that was sent to the presidents and representatives of the AFES member countries by email. Responses from Societies were collated and synthesized to obtain perspectives on the emergent issues in endocrinology in the Southeast Asian region during this pandemic.@*Results@#The burden of COVID-19 cases varied widely across the AFES member countries, with the least number of cases in Vietnam and Myanmar, and the greatest number of cases in either the most populous countries (Indonesia and the Philippines), or a country with the highest capability for testing (Singapore). The case fatality rate was also the highest for Indonesia and the Philippines at around 6%, and lowest for Vietnam at no fatalities. The percentage with diabetes among patients with COVID-19 ranged from 5% in Indonesia to 20% in Singapore, approximating the reported percentages in China and the United States. The major challenges in managing patients with endocrine diseases involved inaccessibility of health care providers, clinics and hospitals due to the implementation of lockdowns, community quarantines or movement control among the member countries. This led to disruptions in the continuity of care, testing and monitoring, and for some, provision of both preventive care and active management including surgery for thyroid cancer or pituitary and adrenal tumors, and radioactive iodine therapy. Major disruptions in the endocrine fellowship training programs were also noted across the region, so that some countries have had to freeze hiring of new trainees or to revise both program requirements and approaches to training due to the closure of outpatient endocrine clinics. The same observations are seen for endocrine-related researches, as most research papers have focused on the pandemic. Finally, the report ends by describing innovative approaches to fill in the gap in training and in improving patient access to endocrine services by Telemedicine.@*Conclusion@#The burden of COVID-19 cases and its case fatality rate varies across the AFES member countries but its impact is almost uniform: it has disrupted the provision of care for patients with endocrine diseases, and has also disrupted endocrine fellowship training and endocrine-related research across the region. Telemedicine and innovations in training have been operationalized across the AFES countries in an attempt to cope with the disruptions from COVID-19, but its over-all impact on the practice of endocrinology across the region will only become apparent once we conquer this pandemic.

Insulin resistance and β-Cell function of lean versus overweight or obese Filipino patients with newly diagnosed Type 2 Diabetes Mellitus / Journal of the ASEAN Federation of Endocrine Societies

Objectives@#To compare the level of insulin resistance and β-cell function between lean and overweight/obese Filipino patients with newly diagnosed type 2 diabetes mellitus (T2DM).@*Methodology@#This was a cross-sectional analytical study including newly diagnosed T2DM Filipino patients from St. Luke’s Medical Center - Quezon City. The patients were classified as either lean or overweight/obese. Age, sex, smoking history, anthropometric measures and blood pressure were obtained. Insulin resistance and β-cell function were determined using the homeostasis model assessment (HOMA). The original model (HOMA1) and the updated model (HOMA2) were used. @*Results@#A total of 80 subjects were included. There were 40 subjects in each group. The overweight/obese subjects had significantly higher mean insulin resistance (HOMA1-IR 9.8±11.7, HOMA2-IR 3.0±2.0) compared to the lean group (HOMA1-IR 2.9±1.5, HOMA2-IR 1.3±0.5). This was consistent in both HOMA1 and HOMA2 (p-values=0.001 and <0.001, respectively). The mean β-cell function of the overweight/obese patients was significantly higher than the lean subjects when using HOMA1 (lean=57.8±35.5, overweight/obese=93.6±66.4, p-value=0.003), but not in HOMA2 (lean=57.6±30.5, overweight/obese=74.8±45.7, p-value=0.051). Overweight/obesity increased HOMA1-IR by 4.0 and HOMA1-B by 46.1 (p-values= 0.002 and <0.001, respectively). Through the use of HOMA2, overweight/obesity increased HOMA2-IR by 1.4 and HOMA2-B by 29.1 (p-values<0.001). Being overweight/obese was also associated with significantly higher odds for developing greater insulin resistance (HOMA1-IR adjOR = 5.6, 95%CI= 1.7-19.2, p-value=0.005; HOMA2-IR adjOR=10.9, 95%CI=3.4-34.9, p-value<0.001) and lower odds for a decreased β-cell function (HOMA1-B adjOR = 0.2, 95%CI = 0.05-0.9, p-value=0.033; HOMA2-B adjOR=0.2, 95%CI=0.04-0.9, p-value=0.043) compared to being lean. @*Conclusion@#Newly diagnosed overweight/obese T2DM had higher mean insulin resistance and β-cell function compared to lean T2DM. Overweight/obesity was also associated with higher odds of developing insulin resistance and lower odds for a decreased β-cell function compared to being lean. The overweight/obese T2DM group also had worse metabolic profile manifested by higher FPG, HbA1c, SGPT and blood pressures compared to the lean T2DM group.

Association of metabolic syndrome with the severity of airflow obstruction in patients with chronic obstructive pulmonary disease / Journal of the ASEAN Federation of Endocrine Societies

@#<p><strong>BACKGROUND.</strong> Metabolic Syndrome (MetS) is common in Chronic Obstructive Pulmonary Disease (COPD) patients but their association is still an unsettled issue. The aim of this study was to determine the association of MetS with the severity of airflow obstruction.</p><p><strong>METHODOLOGY.</strong> This was a cross-sectional analytic study of 157 patients with COPD. They were classified using the Global Initiative for Chronic Obstructive Lung Diseases (GOLD). MetS was assessed using two well-recognized criteria. Demographics, clinical data, lifestyle-related characteristics, fasting blood sugar (FBS) and lipid profile were obtained. Multiple logistic regression was used to determine the association of MetS with the severity of airflow obstruction.</p><p><strong>RESULTS.</strong> 40.13% and 17.20% of patients had MetS using the NCEP/ATP III-AHA/NHBLI and IDF criteria, respectively. MetS was not associated with severity of airflow obstruction. Of the MetS components, only elevated blood pressure (BP) was significantly associated with severity of airflow obstruction (GOLD II: OR=3.28, p<0.001; GOLD III: OR=4.04, p=0.2; GOLD IV: OR=6.21, p=0.04). Elevated FBS was also associated with GOLD IV (OR=16.09, p=0.02). Significant factors associated with MetS in COPD patients were body mass index, inhaled steroid, number of pack-years, and GOLD II.</p><p><strong>CONCLUSION.</strong> MetS is not associated with severity of airflow obstruction. Only certain components of MetS showed significant associations such as elevated BP with GOLD II-IV and elevated FBS with GOLD IV.</p>

Prevalence of Metabolic Syndrome and its individual features across different (normal, overweight, pre-obese and obese) Body Mass Index (BMI) categories in a tertiary hospital in the Philippines / Journal of the ASEAN Federation of Endocrine Societies

Objective@#This study aims to determine the prevalence of metabolic syndrome and its individual components across different BMI categories among patients seen at Wellness Center and Obesity and Weight Management Center, St. Luke’s Medical Center Quezon City. @*Methodology@#This was a 3-year retrospective study of patients seen at the institution from 2013 to 2016. The patients were divided according to Asia-Pacific BMI categories and presence of metabolic syndrome was determined as defined by NCEP/ATP III-AHA/NHLBI (2005). @*Results@#This study included a total of 1367 adult patients with the mean age of 53 (SD= 12.4). The overall prevalence of metabolic syndrome is 51.0%. Its prevalence across the different BMI categories are as follows: 29.6 % with Normal BMI (BMI 18.5-22.9 kg/m2), 38.9% in overweight (BMI 23-24.9 kg/m2), 56.9% in Pre-Obese (BMI 25-29.9 kg/m2) and 62.4% in Obese (BMI ≥30 kg/m2) subgroup. Presence of central obesity using the Asian cut-off has the highest prevalence among patients with metabolic syndrome across all categories. In the group with normal BMI, hypertension and elevated blood glucose were highest with central obesity being the least common but still with 7.3% of individuals meeting the criteria for central obesity.@*Conclusion@#There is high prevalence of metabolic syndrome even in patients with normal BMI. Diagnosis and screening for its individual components should not only be confined to individuals with higher BMI.

Clinical utility of self-reported oral health measures for predicting periodontitis among adult Filipinos with Type 2 Diabetes Mellitus / Journal of the ASEAN Federation of Endocrine Societies

Background@#The likelihood of periodontitis among type 2 diabetes is thrice the non-diabetic population and progresses rapidly when uncontrolled. An inexpensive and easy way of dental assessment via self-reported oral health questionnaire has great potential as a screening tool.@*Objective@#This study aims to validate self-reported oral health measures, socio-demographic and medical variables in predicting the severity of periodontitis in Filipino adults with type 2 diabetes. @*Methodology@#The validated self-reported oral health questionnaires created by the CDC Periodontal Disease Surveillance Project was translated into Filipino and used. A cross-sectional study of 180 participants was conducted in a single institution. Multivariable logistic regression analyses were used to determine significant predictors of serious periodontitis. @*Results@#Male sex [OR=2.17], low educational status [OR=2.98], poor glycemic control [OR=2.58], less frequent dental visits [OR=2.77] and teeth loss >6 [OR=5.02] were considered to be predictive of serious periodontitis. Self reported oral health variables like gum disease –Q1 [OR=8.33], state of gum health –Q2 [OR=0.39], loose teeth –Q3 [OR=63.0], brushing of teeth –Q4 [OR=0.65], use of mouthwash –Q4 [OR=0.69] and poor tooth appearance –Q5 [OR=48.42] were also shown to be significantly predictive of serious periodontitis. A recommended set of questions and proposed scoring system based on the logistic regression analysis of each predictor’s strength was then formulated. @*Conclusion@#The use of specific self-reported oral health questions, certain socio-demographic and medical variables appeared to be highly predictive of serious periodontitis among Filipinos with type 2 diabetes. This provides a cost-effective and rapid method of screening patients who are in need of immediate dental evaluation.

Validation of the oral health screening questionnaire in predicting serious periodontitis among adult Filipinos with type 2 diabetes mellitus / Journal of the ASEAN Federation of Endocrine Societies

@#<p style="text-align: justify;"><strong>BACKGROUND:</strong> Periodontitis affects more than half of patients with diabetes. In resource poor areas in the Philippines, access to routine dental visits may be difficult and thus, a selective approach might be needed to identify those who need dental evaluation and management. An easy-to-administer oral health self-report questionnaire was developed in order to predict serious (moderate to severe) periodontitis.<br /><strong>OBJECTIVE:</strong> The study aims to determine the validity of the Oral Health Screening Questionnaire for Persons with Diabetes (OHSQPD) in estimating the prevalence of serious periodontitis.<br /><strong>METHODOLOGY:</strong> A cross-sectional criterion-referenced study of 175 participants with T2DM were included in the study. They were asked to answer the questionnaire and then made to undergo a full dental examination to identify the presence and severity of periodontitis. The validity of the questionnaire was assessed by determining the sensitivity, specificity, positive predictive value, negative predictive value and area under the receiver-operating curve (AUROC) with the dental examination as the gold standard.<br /><strong>RESULTS:</strong> Using the questionnaire, the prevalence of serious periodontitis was 61% (106) based on an optimal cut-off score of ?12. At this score, the questionnaire yielded a sensitivity of 80.4% and a specificity of 70.6%, with an AUROC of 0.83.<br /><strong>CONCLUSION:</strong> The OHSQPD is a valid tool in detecting serious periodontitis</p>
