Abstract Clinical Case A 17-year old female patient who was diagnosed with type 1 diabetes mellitus (DM) seven years ago, and she had continuously very high blood glucose readings with recurrent admissions to the emergency unit due to attacks of DKA. In addition to a planned diet, she was on more than 250 units of insulin per day (while her weight was 75 kilograms). She was initially on human insulin in the form of twice NPH insulin injections, and pre-meal regular insulin injections, in addition to repeated regular insulin correction doses without any reduction of her blood glucose. Then she was shifted to insulin analogues (to eliminate the possibility of insulin immunogenicity which have been encountered with the use of human insulin), in form of basal insulin Glargine OD, plus pre-meal rapid acting insulin Glulisine without any noticeable response. Continuous switching of her injection sites, with an in-hospital observed insulin injections (to avoid noncompliance), even the use of intravenous route did not help to achieve a glycemic control. Later on, metformin 1000 mg XR BID was added to her daily treatment without any benefit. A screen of anti-insulin antibodies was done and found to be elevated (which should be negative after all these years after her initial diabetes diagnosis). A presumptive diagnosis of EIAS (Exogenous Insulin Antibody Syndrome) was put. A small dose of steroids was administered with close observation (to avoid exacerbation ketosis) without any improvement. Then Cellcept (Mycophenolate mofetil), an immune modulator was added at a dose of 500 mg BID and increased 48 hrs. later to 1000 mg BID and resulted in a minimal reduction of her blood glucose levels. Finally the decision of plasmapheresis was made and an informed consent was obtained from the family after explaining the condition. A good response was recorded after the 1st session, with a minimal decrease of her total daily insulin doses. Later on, an additional excellent response was received during the next 2 sessions with a rapid decline of her glucose readings and her total daily insulin doses. She had recurrent attacks of hypoglycemia during her third and last plasmapheresis session. Her total daily dose of insulin was successfully reduced by more than 50%, and her general condition was improved noticeably without any recorded adverse reactions, as shown in the blood glucose logbook photos attached below.Figure 1:Glucose logbook after the 3rd and last session of Plasmapheresis Table 1:Response parameters to three sessions plasampheresis therapy
