In recent years, the microbiome has been recognized as a key regulator of immune responses. Evidence suggests that changes in the microbiome can lead to chronic disease and even exacerbation of the disease. Impairment of innate immunity resulting from microbial incompatibility may worsen host susceptibility to infection and exacerbate chronic lung diseases. Specific microbes play a key role in ...
normal 0 false false false en-us x-none ar-sa since its first discovery in an iranian male in 1961, zinc(zn) deficiency in humans is now known to be an important malnutrition problem world-wide. it is more prevalent in areas of high cereal and low animal food consumption. the diet may not necessarily be low in zinc, but its bio-availability plays a major role in its absorption. phytic acid is t...
A lot of efforts have been made to elucidate immune mechanisms of TB defense. The studies have identified immune cells, molecules and pathways essential for TB protection. It has been demonstrated that protection depends primarily on the activity of Th1 lymphocytes and macrophages (Schluger & Rom, 1998; Flynn & Chan, 2001; Boom et al., 2003; North & Jung, 2004; Kaufmann, 2006). Th1 cells produc...
BACKGROUND Gestational zinc deficiency has been confirmed to impair the infant immune function. However, knowledge about effects of maternal mild zinc deficiency during pregnancy on hepatitis B vaccine responsiveness in offspring is limited. In this report, we aimed to examine how maternal zinc deficiency during pregnancy influences humoral and cellular immune responses to hepatitis B vaccinati...
cd8 deficiency is a rare primary immunodeficiency with low or absent peripheral cd8 cells which results from tap deficiency, zap 70 deficiency and cd8 α gene mutation. we report a 14 year old female who presented with a history of recurrent pneumonia, bronchiectasis, otitis, severe varicella, herpetic lesions of mouth, bilateral uveitis, and cataract formation since the age of 8 years. she had ...
Background and Objective: Vitamin D is an important factor for calcium hemostasis, and it is responsible for immune system regulation and lowering the risk of inflammatory disease. The aim of this descriptive study was to evaluate the vitamin D level in patients with rheumatoid arthritis (RA) and analyze its possible relation with the severity or the disease. Materials and Methods: This cross s...
Humoral immune deficiencies have been associated with noninfectious disease complications including autoimmune cytopenias and pulmonary disease. Herein we present a patient who underwent splenectomy for autoimmune cytopenias and subsequently was diagnosed with humoral immune deficiency in the context of recurrent infections. Immunoglobulin analysis prior to initiation of intravenous immunoglobu...
Angio-oedema may be hereditary or acquired and is characterised by episodes of potentially life threatening localised tissue oedema and swelling resulting from deficiency of compliment pathway C1 esterase inhibitor. Acquired angio-oedema is about ten times less frequent than the hereditary type and has been associated with immune-deficiency disorders, malignancies and exposure to specific medic...
