Why gout in cml

He was treated with allopurinol, hydroxyurea and analgesics. The arthritis subsided completely within 2 weeks.

He continues in haematologic remission on interferon with no further recurrence of the gout. This is a preview of subscription content, access via your institution.

Either of these tests can be done on granulocytes in the peripheral blood, as they do not require dividing cells. Alternatively, a bone marrow exam provides a sample of dividing marrow cells by aspiration that will demonstrate the t 9;22 by cytogenetic analysis of metaphase cells.

That is, polycythemia vera, essential thrombocythemia, primary myelofibrosis, atypical CML, chronic neutrophilic leukemia. CML has been associated with radiation exposure e.

A high percentage of blasts or basophils may indicate more advanced disease. The peripheral blood smear should be reviewed for dysplasia in the granulocytes. CML in chronic phase typically lacks any dysplasia. Only metaphase cytogenetics will reveal other chromosomal abnormalities that may be present, in addition to the t 9; An elevation in this enzyme level is roughly proportional to the mass of leukemia cells that are turning over.

The ratio of myeloid to erythroid M:E cells is markedly elevated, often to greater than Increased numbers of blasts or promyelocytes, or increased reticulin fibrosis in the marrow can indicate more advanced disease.

Mutation analysis for acquired mutations in the ABL1 kinase domain that interfere with the binding of tyrosine kinase inhibitors TKI to the active site of the enzyme is rarely revealing at initial diagnosis. However, this DNA sequence assay can be very useful if a patient is losing their response to a TKI drug or presents with more advanced disease. Imaging is not typically required, and is not useful in making the diagnosis.

Patients who do not have symptoms rarely require emergency interventions. It is important for patients to stay well hydrated. Because of the increased turnover of myeloid cells, hyperuricemia may be present, and for this reason allopurinol is also indicated. Patients with more advanced disease and large numbers of blasts and promyelocytes in the blood may develop symptoms from leukostasis; the emergency treatment is leukapheresis and institution of hydroxyurea to lower the WBC count rapidly.

The definitive treatment for patients with CML in chronic phase involves one of the oral TKIs: imatinib, dasatinib, or nilotini. Many of these remissions appear quite durable and have been shown to persist for more than 10 years so far. However, a resistant subclone of CML can arise in a small fraction of patients treated with any one of the TKIs; typically this happens within the first years.

This finding requires switching to an alternative TKI or consideration of an allogeneic hematopoietic stem cell transplant HCT. Medical Student Finals Question Bank. ABG Quiz. Reading Chronic Myeloid Leukaemia. Share Tweet. Last updated: November 6, Chronic Myeloid Leukaemia.

Introduction Chronic myeloid leukaemia CML is a cancer of white blood cells that is characterised by the uncontrolled growth of myeloid cells in the bone marrow.

This treatment is not used often for CML, but it may be offered to some people with accelerated-phase or blast-phase CML that has stopped responding to TKI drugs, or to people whose disease is not controlled with chemotherapy.

The process involves destroying the leukaemia cells with very high doses of chemotherapy or radiation therapy. This can also damage the stem cells in the bone marrow , and a stem cell transplant is done to help restore the bone marrow and rebuild the immune system. The stem cells are usually collected from another person allogeneic transplant. Your doctors will tell you if a transplant might help. Transplants are not done at every hospital, so you may need to travel to have this treatment.

Your medical team will explain transplant procedures for your situation and possible side effects. There are several stages of treatment, and the whole process may take many months. Download PDF kB. View all publications or call 13 11 20 for free printed copies.
