401-P: Mortality, Major Adverse Cardiovascular Events (MACDE), and Diabetic Complications in Men with Hypogonadism and Type 2 Diabetes (T2DM) Receiving Long-Term Treatment with Testosterone Undecanoate Injections (TU): 11-Year Real-World Data | Diabetes

Background: Men with hypogonadism are at increased risk of MACE and mortality. Studies in men with T2DM show that testosterone therapy (TTh) reduces both MACE and mortality.

Methods: In a registry of 858 men with hypogonadism, 356 men (41.5%) had T2DM. 178 received testosterone undecanoate injections (TU) 1000 mg/12 weeks (T-group) and 178 opted against treatment (CTRL). MACE, mortality, and diabetic complications were recorded and compared between groups.

Results: Mean baseline age in the T-group and CTRL was 61.8±5.1 and 63.6±4.9 years, respectively. Mean follow-up in T-group vs. CTRL was 7.4 and 8.3 years, respectively. 69 patients (38.8%) in the T-group and 70 (39.3%) in CTRL had a history of cardiovascular disease (myocardial infarction, stroke, or coronary artery disease diagnosis) (p=0.9135). Baseline smoking prevalence was 41.6% (74 men) in the T-group and 38.2% (68 men) in CTRL (p=0.5161). The T-group had significantly worse baseline risk factor profile than CTRL: BMI (36.5±4.5 vs. 33.4±5.3 kg/m²), systolic blood pressure (163.0±13.3 vs. 145.6±14.6 mmHg), LDL (4.7±0.9 vs. 4.1±1.4 mmol/L), HbA1c 9.4±1.4 vs. 7.8±0.7% (p<0.0001 for all). Mortality: during the entire observation period, 13 patients (7.3%) died in the T-group vs. 48 (27.0%) in CTRL (p<0.0001). MACE: in the T-group, there were no cases of myocardial infarction or stroke. In CTRL, there were 55 cases of myocardial infarction (30.9%) and 45 cases of stroke (25.3%). Diabetic complications: in the T-group vs. CTRL, the incidence of retinopathy was 3.4% and 16.9% (p<0.0001), nephropathy 0.6% and 4% (p<0.05), polyneuropathy 6.2% and 54.8% (p<0.0001), diabetic foot syndrome 0% and 9.6% (p<0.0001).

Conclusions: Long-term treatment with TU in men with hypogonadism and T2DM significantly reduces MACE and mortality, as well as diabetic complications compared to untreated controls.

1057-P: Long-Term Testosterone Therapy Results in Remission of Type 2 Diabetes (T2DM) in 34.3% (61 of 178) Men with Hypogonadism and T2DM in a Real-World Registry Study | Diabetes

Background: In 2018, ADA Standards of Medical Care in Diabetes added measurement of testosterone levels in men with T2DM as new recommendation.

Methods: A registry of men with hypogonadism (testosterone ≤12.1 nmol/L) was initiated in 2004 in a urological practice setting. 356 of 858 patients (41.5%) had T2DM diagnosed and treated in a diabetes center. Of these men, 178 received testosterone undecanoate (TU) injections 1000 mg/12 weeks (T-group) following an initial 6-week interval. Anthropometric and metabolic parameters were measured at least twice a year. Fasting insulin was used to calculate HOMA-IR.

Results: After a mean follow-up of 7.7±3.0 (minimum 2, maximum 11 years), 61 patients (34.3%) were in remission, defined as discontinuation of all diabetes medications and stable HbA1c <6.5%. In men who went into remission, HbA1c dropped from 8.7±1.0% at baseline to 5.4±0.1% at the last measurement, HOMA-IR from 10.2±2.5 to 1.7±0.5. In men who never received insulin, HOMA%S increased from 11.1±1.5 to 15.8±2.4. Anthropometric parameters: Body weight declined progressively from 113.6±13.8 to 90.9±8.4 kg by 22.6±8.0 kg, waist circumference from 111.1±7.5 to 98.3±4.6 cm by 12.6±4.3 cm. All patients were on metformin at baseline. 22 patients were on insulin. The average observation time was 130.7±25.9 months (10.9±2.2 years). The average time to discontinuation of diabetes medication was 8.6±2.9 years, average follow-up after achieving remission 2.5±2.3 years. Medication adherence to TU was 100% as all injections were administered in the office and documented. PSA and hematocrit stayed within normal range during the entire observation period.

Discussion: The effects of testosterone were likely mediated by sustained weight loss, increased lean body mass and a profound and sustained reduction of insulin resistance.

Conclusions: Long-term testosterone treatment in men with hypogonadism may result in remission of T2DM.
