Abstract:
There are various complex formations between immunoglobulin and serum enzymes in the body. Of these, LD-Immunoglobulin complex is most common. It has reported that LD-IgG or LD-IgA complex existed in the serum of healthy person or many patients who have various clinical disorders. The clinical significance of complexes is not known, but it results in the increase of total LD activity and interference to the LD isoenzyme electrophoresis interpretation due to its anomalous pattern. We have reported a case of LD-Immunoglobulin complex in AILD(Angioimmunoblastic lymphadenopathy with dysproteinemia) with reference. The patient was admitted with fever, chills and cervical LN enlargement, in LN biopsy, diagnosed AILD, and during treatment expired by sepsis. Since admission, serum total LD activities were increased and serum LD isoenzyme EP showed that LD3-5 fractions was not separated in broad single band. Its pattern was due to LD-immunoglobulin complex, LD-bound immunoglobulin was IgG ,lamda. For the identification of immunoglobulin, we at first did serum protein immunoelectrophoresis. then stained the plate with tetrazolium dye for LD activity.
