Type 1 Diabetes Mellitus and the Use of Flexible Insulin Regimens - Article

ABSTRACT: The management of type 1 diabetes mellitus (formerly known as insulin-dependent diabetes) has changed dramatically over the past 30 years. In particular, new insulin strategies have improved the ability to maintain near-normal glycemia. Factors such as onset, peak and duration of action can influence the ability of a particular insulin regimen to help control glucose levels. Patient factors, including individual variations in insulin absorption, levels of exercise and types of meals consumed, also influence the effectiveness of an insulin regimen. Rapid-acting insulin lispro is an ideal mealtime insulin. The premeal dose of insulin lispro can be adjusted based on the content of the meal and the patient's blood glucose level. Intermediate-acting and long-acting insulins should not be given to account for the content of a specific meal. Long-acting insulin can be administered once daily at bedtime or, ideally, twice daily in addition to another type of insulin. Patients with type 1 diabetes typically require an insulin dosage of 0.5 to 1.0 unit per kg per day. Newly diagnosed patients may have lower initial requirements because of continued endogenous insulin production. Flexible insulin regimens are based on predetermined actions in response to self-monitoring of blood glucose levels and carbohydrate intake.

Diabetic Ketoacidosis: Evaluation and Treatment - Article

ABSTRACT: Diabetic ketoacidosis is characterized by a serum glucose level greater than 250 mg per dL, a pH less than 7.3, a serum bicarbonate level less than 18 mEq per L, an elevated serum ketone level, and dehydration. Insulin deficiency is the main precipitating factor. Diabetic ketoacidosis can occur in persons of all ages, with 14 percent of cases occurring in persons older than 70 years, 23 percent in persons 51 to 70 years of age, 27 percent in persons 30 to 50 years of age, and 36 percent in persons younger than 30 years. The case fatality rate is 1 to 5 percent. About one-third of all cases are in persons without a history of diabetes mellitus. Common symptoms include polyuria with polydipsia (98 percent), weight loss (81 percent), fatigue (62 percent), dyspnea (57 percent), vomiting (46 percent), preceding febrile illness (40 percent), abdominal pain (32 percent), and polyphagia (23 percent). Measurement of A1C, blood urea nitrogen, creatinine, serum glucose, electrolytes, pH, and serum ketones; complete blood count; urinalysis; electrocardiography; and calculation of anion gap and osmolar gap can differentiate diabetic ketoacidosis from hyperosmolar hyperglycemic state, gastroenteritis, starvation ketosis, and other metabolic syndromes, and can assist in diagnosing comorbid conditions. Appropriate treatment includes administering intravenous fluids and insulin, and monitoring glucose and electrolyte levels. Cerebral edema is a rare but severe complication that occurs predominantly in children. Physicians should recognize the signs of diabetic ketoacidosis for prompt diagnosis, and identify early symptoms to prevent it. Patient education should include information on how to adjust insulin during times of illness and how to monitor glucose and ketone levels, as well as information on the importance of medication compliance.
