An electronic MEDLINE search of relevant medical literature published from 1965 to 2007 was performed.,Review,Catamenial diabetic ketoacidosis and catamenial hyperglycemia:case report and review of the literature,22,To date there have been 7 reported cases between menstruation and DKA. The 2 new cases highlight the potentially significant changes in glucose metabolism during the late luteal and decidual phases of the menstrual cycle.,Review,23,Through unclear mechanisms, some women with diabetes mellitus demonstrate significant changes in glucose control around the time of their menses, including DKA. Accordingly, we propose that the terms catamenial DKA and catamenial hyperglycemia be used to refer to these disorders and that catamenial DKA be included in the differential diagnosis list of causes or precipitating events that can lead to DKA.,Review,24,A 32-year-old lady with type 1 diabetes mellitus in whom DKA precipitated 1 to 2 days before her menstrual periods resulting in repeated admissions to hospital.she had similar symptoms starting before each menstrual cycle for the past 5 months.Her urine culture was sterile; electrocardiogram was normal except for sinus tachycardia; and her chest x-ray, ultrasound abdomen, and 2-dimensional echocardiography were also normal. Her complete hormonal profile was done just before her next menstruation (late luteal phase).,Case Report,25,she was advised to increase the dose of insulin from 16 U subcutaneous twice a day to 30 U subcutaneous before breakfast and 20 U before dinner 2 days before the start of her menstrual period. Over the next months, she has not had any episode of DKA prior or during her menstru cycle.The mechanisms by which the menstrual cycle provokes DKA largely remain elusive.,Case Report,26,Goldner with the help of continuous glucose monitoring system demonstrated that increased progesterone level was the main reason for DKA and hyperglycemia during the luteal phase. Javanovic also supported this by demonstrating anti-insulin action of progesterone.,Case Report,27,Trout found a correlation between decreased insulin sensitivity and increased plasma progesterone levels. An average 24% decline in insulin sensitivity was recorded. However, no trends were recorded between insulin sensitivity and plasma estradiol or cortisol level.Several animal studies indicate that progesterone impairs glucose uptake in skeletal and adipose tissues and also augments pancreatic insulin release in animals presumably in response to concurrent insulin resistance.,Case Report,28,Another possible mechanism could be low-grade inflammation. Puder found that C-reactive protein level increased mainly during premenstrual and menstrual period.Alteration in appetite, food habits, and endometriosis have also been implicated in the occurrence of DKA.,Case Report,29,Increasing the dose of insulin in patients with type 1 diabetes mellitus 1 to 2 days before the menstrual period may abort the occurrence of DKA.,Case Report,30,60 例D K A 病人中有肝损害者28 例，男、女各14 例。DKA 伴肝损害的发生率为46 .7%。死亡6 例, 死亡率21.43 % 。统计分析肝功能损害与糖尿病类型、病程、性别、年龄及死亡率无统计学意义一周后复查肝功能, 18 例恢复正常, 6例因于一周内死亡而未能复查, 4 例未恢复( 18 . 18 % ) 。积极保肝治疗。半月后复查, 肝功能全部恢复正常。,DKA导致肝功能异常,刘菊芳.糖尿病酮症酸中毒伴肝脏损害28 例临床分析.重庆医学，1999,28（5）:365-366.,31,DKA 患者98 例,血清转氨酶异常升高者占27. 55%，其中单项丙氨酸氨基转移酶升高者占11. 22%；丙氨酸氨基转移酶和天冬氨酸氨基转移酶均升高者占16. 33%。,DKA导致肝功能异常,张永红.糖尿病酮症酸中毒并肝脏损害临床分析.中国综合临床,2005 ,21 (1 ):26-27.,32,缺氧使肝细胞磷酸化能力降低；由于严重失水、休克、脑血管意外以及手术创伤等, 肝血流量减少, 肝细胞钙膜稳态失调, 肿瘤坏死因子的增加以及氧自由基的产生等一系列神经、体液因子的作用, 引起肝脏内微循环障碍, 肝细胞缺血、缺氧,线粒体肿胀坏死、网状内皮系统功能减退, 导致胆红素及各种肝酶异常。有资料显示, 肝血容量减少6% 10
