A group of 834 Thoroughbred horses was surveyed on four central Florida farms for clinical and epidemiologic features of anhidrosis. In addition, comparative analysis was made of serum thyroxine, serum electrolytes, and fractional urinary electrolyte excretion ratios. An overall disease prevalence of 6.12% was observed. Training horses and nonpregnant broodmares had a predilection for the disease. Adolescent horses were infrequently affected. There was no correlation with sex or color. Comparative clinical signs, related to thermoregulatory compromise, included tachypnea and hyperthermia. Long-term effect included focal and generalized alopecia, decreased appetite, and impaired performance. Previously reported hypothyroidism and hypochloremia were not demonstrated; however, fractional urinary chloride excretion ratios indicated a significant relative conservation of chloride.
对佛罗里达州中部四个农场的834匹纯种马进行了调查，以了解无汗症的临床和流行病学特征。此外，还对血清甲状腺素、血清电解质和尿电解质排泄分数比进行了比较分析。观察到总体疾病患病率为6.12%。训练马和未怀孕的母马易患该病。青春期马匹很少受到影响。与性别或毛色无关。与体温调节受损相关的比较临床体征包括呼吸急促和体温过高。长期影响包括局部和全身性脱毛、食欲下降和性能受损。此前报道的甲状腺功能减退和低氯血症未得到证实；然而，尿氯排泄分数比表明氯有显著的相对潴留。
