Association between 25-hydroxyvitamin D levels and testosterone in healthy, non-obese, young adult, Filipino men / Journal of the ASEAN Federation of Endocrine Societies

Objective@#This study seeks to determine the association between vitamin D and testosterone in healthy, adult Filipino males. @*Methodology@#This cross-sectional study included 110 healthy, non-obese, male volunteers aged 21–40. History and physical exam were taken, and blood was drawn for vitamin D, total testosterone (TT), sex hormone binding globulin (SHBG), albumin, insulin, fasting plasma glucose, and total cholesterol. Free testosterone (FT) was calculated. Vitamin D data were classified by status and TT, FT, and SHBG levels were compared using the Kruskal–Wallis’s test. The associations of vitamin D levels with TT, FT, and SHBG were explored using multiple regression analysis. @*Results@#Vitamin D levels were sufficient in 3 (2.7%), insufficient in 17 (15.45%), and deficient in 90 (81.8%) of the sample. There were no significant differences in the mean TT (p=0.7981), FT (p=0.8768), nor SHBG (p=0.1838) across vitamin D status. Vitamin D was not associated with TT nor FT before or after adjustment for age and age plus body mass index (BMI). Vitamin D was associated with SHBG before and after the aforementioned adjustments, but this became insignificant on sensitivity analysis. @*Conclusion@#There is no association between vitamin D and TT, FT nor SHBG in our cohort with deficient Vit D levels.

UP Philippine General Hospital Division of Endocrinology, Diabetes & Metabolism Consensus recommendations for in-Patient managementof Diabetes Mellitus among persons with COVID-19 / Journal of the ASEAN Federation of Endocrine Societies

@#Diabetes mellitus (DM) is a known risk factor for morbidity and mortality among patients with COVID-19 based on recent studies. While there are many local and international guidelines on inpatient management of diabetes, the complicated pathology of the virus, the use of glucose-elevating drugs such as glucocorticoids, antivirals and even inotropes, and various other unique problems has made the management of in-hospital hyperglycemia among patients with COVID-19 much more difficult than in other infections. The objective of this guidance is to collate and integrate the best available evidence that has been published regarding in-patient management of diabetes among patients with COVID-19. A comprehensive review of literature was done and recommendations have been made through a consensus of expert endocrinologists from the University of the Philippines-Philippine General Hospital (UP-PGH) Division of Endocrinology, Diabetes and Metabolism. These recommendations are evolving as we continue to understand the pathology of the disease and how persons with diabetes are affected by this virus.
