The Prevalence of Male Hypotestosteronism in Type 2 Diabetics in a Southwest Virginia Population Dr. Eric Hofmeister Dr. Christopher Bishop Background Several studies have demonstrated a high prevalence of hypotestosteronism in males with T2DM. The Hypotestosteronism in Males (HIM) study reported the prevalence of hypogonadism in males with T2DM to be 50% The HIM Study 2162 eligible men > 45 years visiting primary care practices in the United States Serum testosterone assessment by a single morning blood draw Hypogonadism defined as total testosterone level < 300 ng/dL with one or more symptoms Prevalence of hypogonadism in males with T2DM was 50% Hypothesis The prevalence of male hypotestosteronism within our local Southwest Virginia population is greater than 50% Objective Determine the Prevalence of hypotestosteronism in males with type II diabetes mellitus (T2DM) within a local population in Southwest Virginia. Design Non-randomized retrospective analysis 13 months Data Analysis of all type 2 diabetic males that had received a total testosterone assessment Methods Solstas Lab Database All patients that had received a total testosterone level assessment over a 13 month period Utilized a T2DM inclusion / exclusion criteria to determine sample population Methods T2DM males assessed for the presence of hypotestosteronism by chart review (Allscripts Database) of a documented total serum testosterone level of less than 300 ng/dL Excluded if no documentation of prior serum total testosteronism < 300 ng/dL Determined percentage of T2DM males with a total testosterone level < 300 ng/dL Inclusion / Exclusion Criteria Male of any age Type II Diabetes A1C > 6.5 or fasting blood glucose > 126 mg/dL Exclude No documented A1C or fasting blood glucose level documentation, Hx of Type I Diabetes, chronic steroid use, or Hx of hypopituitarism Sample Analysis 224 male patients with ≥ 1 serum testosterone 127 excluded (no gluc/A1c) 97 patients with measured testosterone + documented A1c or glucose > 125 38 excluded (DM1, steroids..) 59 patients with measured testosterone + T2DM Results 41/59 (69.5%) have low T with T2DM 18/59 (31.5%) have normal T with T2DM 4 Demographics Mean patient age 54.5 Mean BMI 33.6 Mean testosterone 207 Mean A1c 7.9 Mean serum glucose 144 Concomitant Conditions Opioid use 39 % (16/41) Hypothyroidism 32 % (13/41) Oral hypoglycemics 73 % (30/41) Insulin therapy 41 % (17/41) CVD/CAD/MI 37 % (15/41) Tobacco smoking 37 % (15/41) Discussion Prevalence of T2DM in US high (26 million) and increasing – Increasing incidence of hypotestosteronism ? No current recommendations regarding screening for low testosterone in males Low testosterone associated with insulin resistance and T2DM independent of age, race, BMI 4 Discussion Testosterone supplementation therapy shown in multiple studies to improve: – insulin resistance/utilization – Hemoglobin A1c – serum glucose – DBP – Total, HDL, & LDL cholesterol – increase lean body mass, decrease fat mass, waist circumference 4 Low Testosterone & Cardiovascular Disease Multiple, conflicting studies… the good: Several studies show an inverse relationship between cardiovascular disease and testosterone level – T2DM patients with high-normal testosterone have lower risk (25%) of acute MI vs lowest 25% 4 Low Testosterone & Cardiovascular Disease Multiple, conflicting studies… the bad: Some studies report an increased risk of nonfatal MI in middle-age and elderly patients with pre-existing heart disease given testosterone replacement – National Institute for Aging study – Veterans’ studies (JAMA, NEJM): 26% vs 20% risk of veterans for MI, stroke, and/or death 4 Testosterone Therapy Risks Increased PSA.. worsening BPH Hematopoiesis hyperviscocity Gynecomastia Worsening male breast CA ? OSA/insomnia Decreased spermatogenesis Increased or decreased heart disease? 4 Testosterone Therapy and Prostate Cancer No evidence between exogenous testosterone and increase incidence or progression of prostate CA Current evidence based largely on Huggins & Hodges study (1941). Several studies since 1941 have refuted that evidence… however ??? 4 Final Discussion Higher prevalence of hypotestosteronism in SWVA T2DM patients vs. nationally? Should we screen? Should we recommend therapy? 4
