She was diagnosed with chronic granulocytic leukemia (later referred to as chronic granulocyte leukemia), but fortunately the disease is in the chronic stage and progresses slowly, and the majority of patients can be controlled with reasonable treatment. Should I treat or have a baby first? Will the baby be deformed if the mother has lentile? Can the baby still be kept? A series of questions really worried Xiaoya’s family. Here are some answers to the many questions that arise when pregnancy meets LDS. When can a mother with LCHF wait until after delivery before treatment? For women who have chronic lytic granulocytes, when the blood results show that the white blood cells are less than 100×109/L and the platelets are less than 500×109/L, they can wait until after the birth before treating the disease. But not treating does not mean doing nothing. A mother with chronic granulocytes needs to go to the hospital for regular checkups. If the blood count rises too high it needs to be treated, and the treatment plan needs to be worked out by a hematologist and an obstetrician/gynecologist. What treatment is available for mothers with a change in their condition? If a mother-to-be with chronic disease changes during pregnancy, with white blood cells above 100×109/L and platelets above 500×109/L, treatment is needed. The first step is to improve the blood manifestations. Since patients with chronic granulocytes have a large number of abnormal white blood cells and platelets in their blood, they need to visit the hospital regularly to filter out the excessive white blood cells to prevent them from causing thickening of the blood and obstructing the blood flow; meanwhile, for excessive platelets, anticoagulants can be used to prevent platelets from aggregating and forming blood clots. If the patient is intolerant or the treatment is not effective, he or she can wait until after 6 months of pregnancy to be treated with interferon alpha injections. Because of the large molecular weight of interferon, it is not easy to pass the barrier of the placenta and enter the fetus. Moreover, after 6 months of pregnancy, the important organs of the fetus have basically taken shape, and interferon injection at this time is the least harmful to the fetus. However, even after the 6th month, it is important to avoid tyrosine kinase inhibitors, hydroxyurea and other drugs that may cause fetal malformations if possible. Which patients are not recommended to continue pregnancy? Mothers-to-be in the accelerated and acute phases of slow-grain are not recommended to continue pregnancy, especially in the acute phase. This is because during these two periods, the disease progresses at a faster rate, and if left untreated, the mother’s life is at risk and of course the baby cannot be saved. The pregnancy phase is a physical and psychological test, but pregnancy does not promote the progression of the disease in LDP. It is not a hereditary disease and is not inherited by the fetus. Therefore, the mother should keep a good attitude, not be anxious or nervous, follow the doctor’s treatment plan, and try to have a healthy baby!
