Necrotizing Laryngitis in Patients with Hematologic Disease: The First Case-Report Due to PDR and Literature Review.

Immunocompromised patients with hematologic diseases may experience life-threatening infections with rather uncommon manifestations. Laryngitis has been described as a potential infection in such vulnerable patients and may result in major complications, ranging from impending airway obstruction to total laryngeal necrosis. Immediate laryngoscopy is of paramount importance, as it provides quantification of laryngeal edema and evidence of necrosis.

Tenofovir-Induced Fanconi Syndrome Presenting with Life-Threatening Hypokalemia: Review of the Literature and Recommendations for Early Detection.

Tenofovir disoproxil fumarate (TDF) is a nucleotide reverse transcriptase inhibitor that has been widely used for the treatment of patients with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) infections. Despite the excellent safety records of this regimen, a few cases of acute renal failure and Fanconi syndrome have been reported among HIV patients exposed to TDF. However, in the HBV monoinfection scenario, only five cases of TDF-associated Fanconi syndrome have been reported thus far, two of them providing a confirmatory kidney biopsy.

Colon Adenoma Implicating Myasthenia Gravis: A Case Report of a Patient with Postcolectomy Complications.

We report the case of a 63-year-old patient with myasthenia gravis (MG) due to acetylcholine receptor antibodies (AChR) who underwent colectomy due to colon adenoma and developed myasthenic crisis and anastomosis leakage after surgery. The patient underwent two plasma exchanges, 4 and 6 days preoperatively, and received intravenous prednisolone and immunoglobulin infusion due to the crisis, which included primarily bulbar symptoms. The patient developed on the 10th postoperative day bowel obstruction symptoms and anastomosis leakage which required surgical repair and ileostomy.

Distinct Functions of Autoantibodies Against Interferon in Systemic Lupus Erythematosus: A Comprehensive Analysis of Anticytokine Autoantibodies in Common Rheumatic Diseases.

Objective: Anticytokine autoantibodies occur across a range of hematologic, pulmonary, and infectious diseases. However, systematic investigation of their presence and significance in autoimmune diseases is lacking. This study was undertaken to examine the distinct functions of anticytokine autoantibodies in patients with systemic lupus erythematosus (SLE) compared to patients with other rheumatic diseases and healthy controls.

Anti-aquaporin-4 autoantibodies in systemic lupus erythematosus persist for years and induce astrocytic cytotoxicity but not CNS disease.

Anti-aquaporin-4 autoantibodies are specific for the neuromyelitis optica spectrum disorders (NMOSD) and they have also been described in patients with systemic lupus erythematosus (SLE) with neurological signs consistent with NMOSD. Our objective was to test for the presence and pathogenicity of anti-AQP4 antibodies in SLE patients without neurological disease. Sera from 89 non-CNS-SLE patients were screened for anti-AQP4 autoantibodies.

Clinically significant renal involvement in primary Sjögren's syndrome: clinical presentation and outcome.

Objective: To estimate the prevalence and investigate the clinical features and the outcome of clinically significant renal involvement in a large cohort of patients with primary Sjögren's syndrome (SS).

Methods: Among 715 patients who met the American-European Consensus Group criteria for primary SS, those with clinically significant renal involvement were identified and their clinical and immunologic features were recorded. The prognosis in patients with primary SS with renal involvement was assessed by the clinical appearance of any of the following major outcomes: death, hemodialysis, chronic renal failure (CRF), and lymphoma.

Autoantibodies in Sjögren's syndrome: clinical presentation and regulatory mechanisms.

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease mostly affecting the exocrine glands. A large number of autoantibodies have been detected in the serum of patients with pSS. Among them, anti-Ro/SSA and anti-La/SSB autoantibodies are the most common; they serve as disease markers and are involved in the pathogenesis of neonatal lupus syndrome (NLS).
