Diagnosis
Diagnosis of the prothrombin G20210A mutation is straightforward because the mutation involves a single base change (point mutation) that can be detected by genetic testing, which is unaffected by intercurrent illness or anticoagulant use.Measurement of an elevated plasma prothrombin level cannot be used to screen for the prothrombin G20210A mutation, because there is too great of an overlap between the upper limit of normal and levels in affected patients. Treatment
Patients with the prothrombin mutation are treated similarly to those with other types of thrombophilia, with anticoagulation for at least three to six months. Continuing anticoagulation beyond three to six months depends on the circumstances surrounding thrombosis, for example, if the patient experiences a thromboembolic event that was unprovoked, continuing anticoagulation would be recommended. The choice of anticoagulant (warfarin versus a direct oral anticoagulant) is based on a number of different factors (the severity of thrombosis, patient preference, adherence to therapy, and potential drug and dietary interactions).Patients with the prothrombin G20210A mutation who have not had a thromboembolic event are generally not treated with routine anticoagulation. However, counseling the patient is recommended in situations with increased thrombotic risk is recommended (pregnancy, surgery, and acute illness). Oral contraceptives should generally be avoided in women with the mutation as they increase the thrombotic risk.
Prevention
Diabetics
The prevention of hypoglycemia depends on the cause. In those with diabetes treated by insulin, glinides, or sulfonylurea, the prevention of hypoglycemia has a large focus on patient education and medication adjustments. The foundation of diabetes education is learning how to recognize the signs and symptoms of hypoglycemia, as well as learning how to act quickly to prevent worsening of an episode. Another cornerstone of prevention is strong self-monitoring of blood glucose, with consistent and frequent measurements. Research has shown that patients with type 1 diabetes who use continuous glucose monitoring systems with insulin pumps significantly improve blood glucose control. Insulin pumps help to prevent high glucose spikes, and help prevent inappropriate insulin dosing. Continuous glucose monitors can sound alarms when blood glucose is too low or too high, especially helping those with nocturnal hypoglycemia or hypoglycemic unawareness. In terms of medication adjustments, medication doses and timing can be adjusted in order to prevent hypoglycemia, or a medication can be stopped altogether. Non-diabetics
In those with hypoglycemia who do not have diabetes, there are a number of preventative measures dependent on the cause. Hypoglycemia caused by hormonal dysfunction like lack of cortisol in Addisons disease or lack of growth hormone in hypopituitarism can be prevented with appropriate hormone replacement. The hypoglycemic episodes associated with non-B cell tumors can be decreased following surgical removal of the tumor, as well as following radiotherapy or chemotherapy to reduce the size of the tumor.
