Jason An, Branko Braam
Rationale: We hope to increase awareness that hypokalemic paralysis may be the first presentation of Sjögren syndrome, for which potassium-sparing diuretics can be an effective adjunct to potassium replenishment. Presenting concerns: A 73-year-old female presented to a peripheral hospital with quadriparesis and a critically low serum potassium of 1.6 mmol/L with U waves on the electrocardiogram (ECG). The initial arterial blood gas showed a pH of 7.19, bicarbonate of 13 mEq/L, and a CO2 of 35 mm Hg...

REVIEW
Fatemeh Mohammadpour, Mona Kargar, Molouk Hadjibabaie
Immune Thrombocytopenia (ITP) is an autoimmune disease in which platelet destruction causes thrombocytopenia. Due to the known steroid toxicities, alternative agents have been evaluated for the treatment of these patients. We aimed to review the literature and find evidences regarding the potential benefits of hydroxychloroquine (HCQ) as a steroid-sparing agent in the treatment of ITP. We searched English language articles within Web of Science, PubMed, and Scopus. Cohorts, clinical trials, case reports, conference papers, and letters were included...

Lobular fibrosis in labial salivary glands of patients with systemic autoimmune disease is a rarely examined and rather neglected histological change. Its significance and disease association is poorly understood. Our aim was to explore the clinical correlations of fibrosis in labial salivary gland samples using objective methods and laboratory parameters. Labial salivary gland samples from more than 300 patients over a 3-year period were selected from the archives of the pathology department, histologically examined, digitised, image analysed and statistically evaluated to identify the presence and intensity of lobular fibrosis, its relation to age, clinical diagnoses of systemic autoimmune disease and the presence of rheumatoid factor (RF), anti-cyclic citrullinated peptide (CCP), antinuclear antibodies (ANAs), and anti-dsDNA serum markers...

Valproic acid (VPA) has been reported to inhibit cancer cell growth and has therapeutic use in retinal diseases. However, the mechanism of this action remains unclear. In order to explore this mechanism, primary human retinal pigment epithelial (hRPE) cell cultures were established. Cell viability was assessed by the trypan blue exclusion method (T), and the cell proliferation was measured by 3 H-thymidine incorporation (3H-thy). P38 synthesis was quantitated by using 14C-methionine-labeled P38 (14C-P38) by using P38-specific antibody...

Background: Chronic hypersensitivity pneumonitis (HP) is the most common cause of diffuse parenchymal lung disease (DPLD) in India. There is no data regarding the avian antigen exposure-associated DPLD from the country. Methods: Chronic HP from exposure to avian antigen was diagnosed when the high resolution computerized tomography (HRCT) showed features for HP and was supported by the history of exposure to pigeons, the presence of precipitin antibodies (IgG) to avian antigen in high titre with negative rheumatoid factor, antinuclear antibody, and no clinical clue for a collagen vascular disease...

Numerous autoantibodies are implicated in the pathogenesis of autoimmune epilepsy. In the past decade, many case series reported the association of glutamic acid decarboxylase 65 (GAD 65) antibodies with epilepsy. Conjoint presence of GAD 65 antibodies with antinuclear, anti-thyroid, and anti-parietal cell antibodies has often been demonstrated. However, concomitant elevated levels of GAD 65 and P/Q voltage gated calcium channel (VGCC) antibodies is rare. We report a case of autoimmune epilepsy with conjoint GAD 65 and P/Q VGCC antibodies in the absence of malignancy...

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that mainly affects the joints, therefore, may cause deformities and disability if untreated. The first line of treatment is disease-modifying antirheumatic drugs (DMARDs). When the patient fails to respond to DMARDs, mainly methotrexate, then second-line therapy is required. Tumor necrosis factor α (TNFα) plays an important role in the pathogenesis of RA; however, the treatment with anti-TNFα medications is challenging. It may trigger the autoimmune system and result in producing antibodies that induce symptoms and signs mimic to systemic lupus erythematosus (SLE), and in rare situations can affect vital organs with severe and life-threatening complications...

Herpes simplex virus (HSV) types 1 + 2 immunoglobulin (Ig)M antibodies assays are important tools for diagnosing pregnant women and their newborns. However, it is unclear whether high levels of rheumatoid factor (RF) interfere with serological methods used to test for HSV types 1 + 2 type-specific IgM antibodies. We report a case of a false-positive result for HSV 1 + 2 IgM antibodies due to gross overestimation of RF by enzyme-linked immunosorbent assay (ELISA). This result occurred in a 25-year-old Han Chinese woman who was 28 weeks pregnant with a fetus (sex of fetus unknown)...

Antinuclear autoantibodies (ANA) displaying a dense fine speckled pattern (DFS, ICAP AC-2) on HEp-2 cells are frequently observed in clinical laboratory referrals, often associated with anti-DFS70 specificity. Anti-DFS70 positive patients rarely develop systemic autoimmune rheumatic disease (SARD), especially in the absence of clinical evidence or additional anti-extractable nuclear antigen (ENA) antibodies, prompting suggestions that an isolated DFS70-specific ENA may be an exclusionary finding for SARD. In this study, the frequency and diagnostic significance of anti-DFS70 autoantibodies was investigated in a community hospital cohort of patients undergoing routine ANA testing...

Objective Salivary gland ultrasound (SGU) is a reliable technique for assessing the salivary glands in patients with primary Sjögren's syndrome (pSS). The aim of this study was to elucidate the relationship between SGU findings and autoimmunity in patients with pSS. Methods Patients with pSS underwent an SGU assessment. The patients were classified into three groups according to their autoimmunity profile: the complete positive group (positive rheumatoid factor, antinuclear antibodies, and anti-Ro/anti-La antibodies), the partial seropositive group (positivity of at least one autoantibody but not all), and the seronegative group...

Antinuclear antibodies (ANA) are prescribed as first-line autoantibodies in suspicion of mainly systemic autoimmune diseases. They include antibodies recognizing antigenic structures localized in the nucleus of cells, but also in the cytoplasm, at the membranes or transitional structures related to the cell cycle. Their research is based on screening and identification tests. For these tests, there is little or no standardization and harmonization of professional practices is necessary. From a questionnaire sent to healthcare professionals involved in the realization and interpretation of tests of autoimmunity, an overwiew of routine practices for the research of the ANA and their identification, was directed by the EASI Group International...
