Abstract
IgD myeloma is very rate. It differs from multiple myeloma of other classes in several aspects and its laboratory diagnosis may be difficult, as total plasma protein concentration is often normal, and a paraprotein peak may not be easily demonstrable by the conventional electrophoretic techniques. We report here two cases of IgD myeloma investigated in this laboratory. Immunochemical, biochemical, and hematological studies were carried out: Serum total protein values were within normal range. Quatitation of serum immunoglobulins revealed a decrease in the level of IgG, IgA, and IgM. Bence Jones proteinuria of l type was present in both patients. Serum immunoelectrophoresis, using specific antisera, showed the presence of IgD l paraprotein the diagnosis of IgD myeloma was made after further investigations. Our findings indicate that all patients who have been suspected to have multiple myeloma should be investigated for IgD and IgE myeloma

Abstract
?2 microglobulin (?2M) fibril has been recognized as the major factor of dialysis-related amyloidosis. Elevated serum levels are thought to be the basis for tissue deposition. In order to evaluate the effect of cellulosis membrane (FB 110) and treatment duration on S?2M levels, we determined serum levels in 23 hemodialyzed patients with end-stage renal failure. S?2M levels were markedly elevated in all patients with a mean of 74.71 (SD=21.2 mg/l, range: 46 mg/l after 2 years hemodialysis-123.8 mg/l after 10 years treatment) that statistically is higher than healthy subjects (P<0.0001). Serum ?2M in 19 healthy subjects was 2.36 (SD=0.4 mg/l, rang: 1.58-3.3 mg/l). Although in hemodialysis group, no significant correlation was found between S?2M and age or sex but increased serum levels of ?2M had significant correlation with duration of hemodialysis treatment (r=0.53, P<0.01). Since the dialysis membrane has a very effective role in clearance of S?2M, we suggest that the particular effort should be made towards improvement of dialysis membranes.
