请美国家庭医生的会诊问题:
1 假若她在美国,且是你的病人,你将对如何管理她目前的糖尿病状况,理由是什么?
2 你如何监测她的血糖,如何选择检测空腹血糖、餐后血糖和糖化血红蛋白?
3 就饮食来讲,对居住在美国的中国糖尿病病人,你会给出怎样的建议?
美国 Wiscomsin大学 Jonathan L.Temte教授对病例的分析
此 65岁女性糖尿病病人的病情已进展至需用胰岛素治疗的程度。这在糖尿病自然病史中极为常见。目前,她的血糖已达 8.8~17 mmol/L,很明显,需要加强对血糖的控制力度。
我会选择家庭用血糖议用于监测她的血糖。要获得早餐前、中餐前、晚餐前及就寝前的相关数据。通常,我会要求每周 3~4天进行血糖检测,每天 4次,回诊所看病前,要做 2周这种监测。这样就诊时我会得到 24~32个血糖值。根据这些血糖值,我会为病人选择短效和长效 (NPH,中性鱼精蛋白胰岛素)胰岛素联合治疗,比例为:70%短效胰岛素和 30%长效胰岛素。常规,胰岛素应每日给 2次,早餐前给剂量的2/3,晚餐前给 1/3。
由于血糖呈波动状态,所以需检测病人的糖化血红蛋白以观察疗效。我会要求病人继续做好上面提到的 4次家庭监测。我会给病人做尿微量清蛋白 (和尿微量清蛋白与尿肌酐比值)检测,用于糖尿病肾病的评估,若升高,用某种血管紧张素转换酶 (ACE)抑制剂做早期干预。密切观察血压的变化至关重要,若病人的血压 >130/80 mm Hg,我会给病人用某种 ACE抑制剂。密切注意血脂变化,包括总胆固醇、低密度脂蛋白(LDL)、高密度脂蛋白 (HDL)和三酰甘油,若血脂高应开始用他汀类药物。最后,应对足感觉缺失、皮肤硬结和出现的溃疡做出评估,应每年进行糖尿病视网膜病变检查。
为了能对饮食结构提出合理的建议,有必要了解病人目前的饮食状况。为了能产生好效果,提高自我意识,我更喜欢让病人提供 3 d的饮食日志。就诊期间,对其饮食、所建议的卡路里摄入 (和摄入量)目标做简要评诉、对食物的血糖指数也要做评诉。我会表扬病人能每日做运动锻炼,并鼓励其坚持下去。

c/o poor glucose control
History of presenting complaint
65 year old diabetic woman.
10 years ago presented with symptoms of polydipsia,′feeling hungry all the time′,weight loss.
She attended a Chinese medicine hospital and her fasting glucose was 13 mmol/L,urine glucose++.Shewasprescribed glipizide and acarbose tablets.Fasting glucose have been controlled at about 7 mmol/L and postprandial glucose at 8 mmol/L.
Two years ago her fasting glucose rose to about 9 mmol/L and postprandial glucose of about 10 mmol/L.She attended Long Hua hospital(a district hospital of Western medicine).She was initiated on insulin(Novolin N 8 units at night).A year later her glucose level became unstable again and her insulin was increased to 10units in the morning and 6 units at night.She was also started on metformin 0.5g three times a day and acrbose 50mg three timesa day.Her latest fasting blood sugar was 8.8 mmol/L and postprandial glucose of 17 mmol/L.
She said she feelstired and′weak in the legs′,dizzy and light headed at times and chest discomfort,paresthesia in the extremities.She also noted mouth ulcers and fetor in her mouth.She denied any urinary urgencyor fluid retention.Has normal warmand pain sensation in her feet.She managesregular daily exercise and has 4 light mealsa day.
Past medical history
Hypertension for 3 yearsand stable on medication.
Raised cholesterol for 3 yearsand still raised.
Rheumatoid arthritisfor 30 years.Wason aspirin but stopped due to melena.
On examination
Look well.No edema in the eyelidsand no mouth ulcers noted.Throat not red.No enlarged lymph nodes.
BP 130/80 mmHg.P 68/min regular.Normal heart sounds.No swelling in the lower limbs.
Lung fields were clear.
Abdomen soft.No palpable liver or spleen.
Feet:skin feels warm,no ulcers and palpable foot pulses.
Normal neurological reflexes.
Investigation
Liver function,renal function,CBC,ECG,urine analysis:normal
Blood lipids:raised.
HbA1c:nottested
Questions:
If she was your patient in US
1.How would you manage her diabetesnow and why?
2.How would you monitor her diabetes,particularly the choice of using fasting glucose,postprandial glucose and HbA1c?
3.How would you give dietary advice to a diabetic Chinese patient in US?
This 65 year-old woman has progressed in her diabetes to the point of having an insulin requirement.Thisis very common in the natural history of diabetes.At this time,given that her blood sugars are 8.8 to 17 mmol/L,consideration isneeded to greatly improve her control.
(1)Additional information isneeded to adjust insulin dosing.
I would have thispatient check her blood glucose using a home glucometer.Readings should be obtained before breakfast,before lunch,before dinner and at bedtime.Iusually request 3-4 readingsfor each time each week and request this be done for two weeksbefore seeing the patient back at my clinic.Hence,at the follow-up visit,I will have 24-32 blood glucose readings with which to make decisions.Based on the readings,Iwould start the patient on a combination of short-acting and long-acting insulin in a proportion of 70%short-acting and 30%long-acting(NPH)insulin.The insulin should be given twice a day with roughly 2/3 of the dose before breakfast and 1/3 before dinner.
(2)Monitoring of diabetesand other metabolic parameters.
Because of the tendency of blood glucose readingsto fluctuate,hemoglobin A1c levelsshould be obtained to monitor therapeutic effect.Iwould have the patient continue home monitoring at the four times noted above.Iwould also check for urine microalbumin(and microalbumin to urine creatinine ratio)to assessfor diabetic nephropathy and intervene early with an ACEinhibitorif elevated.Careful monitoringof BPs isessential and Iwould use an ACEinhibitor if BPs aregreater than 130/80.Careful evaluation of the blood lipids,including total cholesterol,LDL,HDL and triglyceride should be performed and statin therapy should be initiated for elevationsof lipids.Finally,an assessment for sensorylossto feet and the presence of calluses and ulcersshould be performed routinely asshould an annual diabetic retina examination.
(3)Providing dietary advice.
To provide sound advice on dietary changes,it is necessary to understand the patient′scurrent diet.Tofacilitate this and provide self-awareness,Ilike to have the patient record a 3-day food diary.A brief review of foods,suggested calorie(and quantity)goals,and a review of the glycemic indexof foods isthen covered during the visit.Iwould also compliment this patienton her usual daily exercise and encourage her to continue this.
