Abstract

Case A 41-year-old male presented with abdominal pain, diarrhea, weakness, and shock. He was diagnosed with cardiac tamponade, underwent pericardial drainage and initiation of broad-spectrum antibiotics. The patient had a recent admission with bilateral pleural effusions, with negative infectious and malignancy workup. Macrocytic anemia, increased white blood cells, incidental abdominal abscess and splenic infarcts were found during this admission. Investigations again demonstrated elevated white blood cells (53.8% neutrophils, 12.1% lymphocytes, 29.7% monocytes) and anemia. Autoimmune workup was unremarkable except for presence of atypical ANCA and lupus inhibitor. Bone marrow biopsy was non-specific. He had low IgM and IgG levels suggesting a diagnosis of Common Variable Immunodeficiency (CVID). He received intravenous Solumedrol after his respiratory status deteriorated. He improved and was transitioned to prednisone, but a pathogen was never found. His positive response to steroids with worsening symptoms with prednisone taper initiation suggested that this was an autoimmune process. He was started on Hydroxychloroquine and intravenous immunoglobulin by Rheumatology. However he was subsequently diagnosed with Chronic Myelomonocytic Leukemia (CMML) based on cytogenetic studies by Hematology. Current treatment includes hydroxyurea and prednisone. Discussion This patient demonstrates the challenge of diagnosing autoimmunity in a patient with low levels of immunoglobulins such as in CVID. How to interpret autoimmune antibody titres in autoimmune conditions is unknown. Most literature describes immunodeficiency being diagnosed after the autoimmune condition [1] and often after immunosuppressant use. Studies on systemic lupus erythematosus and CVID have shown low levels of autoantibodies after immunodeficiency diagnosis.

3. Is response to IVIG in Chronic Idiopathic Urticaria related to presense of autoantibodies?

Abstract

Background Treatment of Chronic Idiopathic Urticaria (CIU) may be challenging, as patients can be refractory to various treatments. This may be due to an autoimmune mechanism in its pathogenesis. CIU has been shown to be associated with autoantibodies to IgE or IgE receptor and with thyroid autoimmunity [1,2]. Treatments targeting this autoimmune pathogenesis are now being used, such as intravenous immunoglobulin (IVIG). We reviewed patients with CIU treated with IVIG to see if response to treatment correlated with presence of autoimmunity (antibodies to IgE/IgE receptor or Thyroidperoxidase (TPO) antibodies).

Abstract

Background Wheat Dependent Exercise Induced Anaphylaxis (WDEIA) is a form of Food Dependent Exercise Induced Anaphylaxis. WDEIA occurs when there is an allergic reaction following the ingestion of wheat, coupled with exercise [1]. The suspected allergen that is responsible for WDEIA is omega5gliadin [2]. We report a series of adult clinical cases of WDEIA recorded between 2006-2009 at Health Sciences Centre (Winnipeg). The purpose of this study was to compare the results of Skin Prick Test (SPT) to commercial wheat extract and wheat flour in patients with WDEIA.
