The response to testosterone undecanoate in men with type 2 diabetes is dependent on achieving threshold serum levels (the BLAST study)

Abstract: Testosterone undecanoate significantly improves sexual parameters and Ageing Male Symptom Score, but not metabolic factors at 30 weeks in men with SEVERE testosterone deficiency syndrome (TDS). In men with MILD TDS, significant improvements in metabolic but not sexual parameters were seen, suggesting that there are threshold levels for response to testosterone replacement therapy and that trials of therapy need to achieve sustained therapeutic levels to be effective. PSA showed minor rises, but only for 30 wee… Show more

“…In a double-blind placebo-controlled study, patients with severe hypogonadism (TT<8 nmol/L or FT <180 pmol/L) receiving testosterone undecanoate reported improved sexual function at 30 weeks follow-up, although there was no significant improvement in sexual function in patients with mild hypogonadism at baseline (TT 8.1-12 nmol/L or FT 181-250 pmol/L). 28 Another study showed that, in patients with TT <9.54 nmol/L, treatment with testosterone gel was associated with improved responses to phosphodiesterase 5 (PDE5) inhibitors in comparison with placebo. 29 In patients receiving testosterone replacement therapy (TRT), beneficial effects on reported quality of life and sexual interest may manifest as early as 3 weeks, although effects on erectile function may take up to 6 months.…”

“…Установлено, что восстановление тестосте-рона до физиологических уровней путем назначения ТЗТ приводит к улучшению соматических и метаболических показателей у пожилых мужчин с ожирением, возрастным гипогонадизмом и нарушениями гликемии натощак [71]. Кроме того, терапия препаратами тестостерона оказывает положительное влияние на улучшение компенсации СД, что сопровождается снижением уровня гликированного гемоглобина, инсулина и повышению чувствительность к нему [72,73,74]. Так, в многоцентровом проспективном рандомизированном двойном слепом плацебо-контро-лируемом исследовании TIMES изучались эффекты ТЗТ с использованием трансдермального геля, содержащего 2% тестостерона, в отношении инсулинорезистентности, сердечно-сосудистых факторов риска и других симптомов у 220 мужчин с гипогонадизмом и СД2 и/или метаболи-ческим синдромом.…”

“…2 Non-responders to PDE5Is are frequently salvaged with testosterone if baseline levels are below 10nmol/L. 3 Frequent or daily dosing with a PDE5I can salvage up to 50% of patients who fail to respond to on-demand therapy.…”
