Dry eye is a common eye disease, and suitable animal models are indispensable for investigating the pathogenesis and developing treatments for dry eye. The present study was conducted to develop an androgen deficiency dry eye model induced by finasteride, and to evaluate ocular surface status and inflammatory cytokine gene expression in the lacrimal gland using a cytokine antibody array system....
Aim: The prevalence of celiac disease (CD) in patients with iron deficiency (ID) is estimated at 0-6% in European countries. The prevalence of celiac disease in patients with iron deficiency in the USA is unknown. Given the treatable nature of gluten hypersensitivity, estimating the prevalence of CD in patients with ID can help to determine the need to screen these patients for occult CD. Metho...
The most common of the primary immunodeficiency diseases are those that involve inadequate antibody production. The characteristic presentation of these disorders is recurrent sinopulmonary infections. An arrest in B cell development at the pre-B cell stage leads to agammaglobulinemia and an insignificant number of B cells. X-linked agammaglobulinemia is the most common of these developmental a...
BACKGROUND αKlotho is the prototypic member of the Klotho family and is most highly expressed in the kidney. αKlotho has pleiotropic biologic effects, and in the kidney, its actions include regulation of ion transport, cytoprotection, anti-oxidation and anti-fibrosis. In rodent models of chronic kidney disease (CKD), αKlotho deficiency has been shown to be an early biomarker as well as a pathog...
Bronchiectasis is a chronic debilitating condition characterized by abnormal dilated thick-walled bronchi. To investigate humoral immune function in bronchiectatic patients, this study was performed. Forty patients with established diagnosis of bronchiectasis, who were referred from two tertiary care pulmonology centers in Tehran, were investigated in this study. Immunoglobulin isotypes concent...
OBJECTIVE To characterize factors that contribute to symptomatic narcolepsy and excessive daytime sleepiness in neuromyelitis optica and multiple sclerosis. SETTING Japanese university hospitals. DESIGN Case study. PATIENTS Seven Japanese patients whose initial diagnoses were multiple sclerosis and who were exhibiting excessive daytime sleepiness. MAIN OUTCOME MEASURES Lesions on magnet...
Deficiencies in transmembrane activator and CAML interactor (TACI) result in common variable immune deficiency, a syndrome marked by recurrent infections with encapsulated microorganisms, impaired production of antibodies, and lymphoproliferation. How TACI promotes antibody production and inhibits lymphoproliferation is not understood. To answer this question, we studied the generation of immun...
PURPOSE The clinical features of patients with celiac disease (CD) are variable. In the present study, clinical and laboratory features of 109 patients with CD were retrospectively evaluated. MATERIALS AND METHODS In all cases, diagnosis of CD was made by European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) criteria and clinical and laboratory findings, includi...
Calculated globulin (total protein - albumin) is usually tested as part of a liver function test profile in both primary and secondary care and determines the serum globulin concentration, of which immunoglobulins are a major component. The main use hitherto of calculated globulin is to detect paraproteins when the level is high. This study investigated the potential to use low levels of calcul...
Most individuals carry two wild-type M alleles of the SERPINA1 gene which encodes a1-antitrypsin. 95% of severe deficiency of a1-antitrypsin is associated with the Z allele (Glu342Lys; denoted PiZZ in the homozygote), and with the retention and polymerisation of a1-antitrypsin within hepatocytes [1]. These polymers are contained within periodic acid–Schiff-positive, diastase-resistant inclusion...
