Hallo, My friend (age 29) for over a year has severe anemia, but at the moment the doctors don\'t know what it is. At the beginning they suspected the myelodysplastic syndrome. The bone marrow biopsy made 3 times, didn\'t reveal any abnormalities. Lymphoma, leukemia, cancer and proxysmal nocturnal hemoglobinuria, celiake and ednocrine diseases have been exluded. Gastroscopy, colonoscopy and abdominal ultrasound also came out in ok. Viscerial arteriografia also unchenged, thickening of the iheum and jejunum was only noticed.My friend has a low level of iron and potassium but the intravenous administration minimally raises the hemoglobin level. It was initialy enough to roll blood once every 3-4 weeks, but since 3 months administration of two units of blood rises hemoglobin for only 0,5 while it can decrease during the day even by up to 1. My friend occasionally complains of pain in the lower spine and kidney area. She also suffersasthma and is allergic. Today the doctor told her that he could only give her blood and iron and wait as the illness developes. If it\'s possible, I\'d like to consult. I can send a mail with the results.Best regards Justyna from Poland
