There was a decrease in breath sounds at the base of both lungs. and diuretics were ineffective. Moderate anemia worsened and transfusion was necessary. Hematological examination revealed plasma cells in the peripheral blood and a hematologist was consulted. On Rabbit Polyclonal to OR52D1 physical examination, there was anemia in the connective pulp, and heart sounds showed a systolic murmur. There was a Amphotericin B decrease in breath sounds at the base of both lungs. Bilateral presidia-pitting edema was evident. Hematological examination revealed anemia (hemoglobin 7.7?g/dl) with plasma cells in the peripheral blood (18%). Total serum protein was 6.0?g/dl with 64.9% albumin and 14.5% -globulin. Creatinine 1.35?mg/dl, blood urea nitrogen 27?mg/dl, uric acid 13.3?mg/dl, and lactate dehydrogenase 679?IU/L (reference range 230C460). Immunoelectrophoresis showed monoclonal IgD () in the serum and Bence Jones protein () in the urine. Quantitative immunoglobulin determination showed a marked increase in IgD, 934?mg/dl, while IgG, IgA and IgM levels were decreased (Table?1). Bone marrow aspiration resulted in dry tap and biopsy results showed multiple myeloma. Chest X-ray results showed bilateral Amphotericin B pleural effusion, whereas X-ray examination of the rest of the body was normal. Echocardiography results did not indicate amyloid deposition in the myocardium, but the ejection fraction was decreased because of a previous myocardial infarction. Table?1 Laboratory findings locus, although the break points in myeloma may be different from those observed in mantle cell lymphoma. The protooncogene c-myc is translocated to the IgH locus at 14q32, resulting in increased expression of the oncogene because of strong immunoglobulin enhancers . 14q32 has been detected in 74% of patients with multiple myeloma, by fluorescence hybridization, and in 85% of plasma cell leukemia cases . 14q32 is one of the factors related to a poor prognosis. These translocations are found in the earliest stage of the disease, suggesting that such translocations are an early and possibly initiating event in the disease development . The detection of genetic changes is important, not only because of their association with clinical prognosis, but also because they can be used as measurable targets for response to treatment. Malignant effusions can occur in the terminal stage of the disease and are difficult to treat. This particular case of multiple myeloma had a poor prognosis and required appropriate therapy. In general, with the appearance of malignant effusions, systemic Amphotericin B chemotherapy and drainage are necessary. In IgD myeloma, most patients tend to be younger than other myeloma patients, and there are likely a large number of eligible cases. As a therapeutic approach for IgD myeloma, especially the type, we consider that peripheral blood stem cell transplantation will result in a good prognosis after conventional chemotherapy.
