Selective immunoglobulin A deficiency (SIgAD) primarily leads to recurrent infections and autoimmune diseases: A retrospective study of Chinese patients in the past 40 years

Publication date: Available online 30 October 2019Source: Genes &DiseasesAuthor(s): Wei Wang, Tianhao Yao, Tianyi Zhang, Meiying Quan, Changyan Wang, Chen Wang, Lejia Zhang, Xiaoyan Tang, Shan Jian, Hongmei SongAbstractSelective immunoglobulin A deficiency (SIgAD) is considered to be the most common human primary immune-deficiency disease in the world. However, the incidence in China is obviously lower than Caucasian races. The definitionof SIgAD has changed over time with the progress of people's understanding. The scientific community did not reach a consensus on the definition until 1999. As a result, many previously reported cases need to be excluded under the current definition.SIgAD can lead to several spectra of diseases including infections and autoimmune diseases. We retrospectively summarized the SIgAD patients in Peking Union Medical College Hospital(PUMCH), and summarized the Chinese SIgAD reported in China and abroad in past 40 years. Fourty three SIgAD patients were confirmed in the study, in which 9 were healthy without clinical symptoms. Of the 34 patients with clinical symptoms, recurrent infections were found in 29 (85.3%) patients; 13 (38.2%) patients were with autoimmune diseases; 6 (17.6%)cases had allergic symptoms; 3 patients (8.8%) were with tumors, only one case (2.9%) had a family history. Compared with other countries, sIgAD patients in China showed similar symptoms, but the rate of recurrent infections and autoimmune diseases were higher than s...

Authors: Zhao Q, Shi JX, Hu R, Li Q, Zhang CY, Li JS Abstract To date, the efficacy of glucocorticoid therapy to reduce mortality in patients with acute respiratory distress syndrome (ARDS) has remained controversial among the studies available. The present meta-analysis study aimed to further clarify the impact of glucocorticoid therapy on mortality in patients with ARDS by performing a pooled analysis of the previous data. The PubMed, Chinese Knowledge Infrastructure, Wanfang and Cochrane trials databases were searched for relevant studies published between 1966 and 2016. Randomized controlled trials (RCTs) that ...

It is known that the immune system has an important role in the pathogenesis of autoimmune diseases but also in the chronic lymphoproliferative malignancies. In this process of autoimmunity associated with immunodeficiency, the CLL neoplastic cells, the non-malignan...

The polymeric materials present in the biofilm architecture hinder the entry of antimicrobial compounds through the surface of bacterial cells which are embedded as well as enclosed beneath the biofilm matrix. Recent and past studies explored the alternative approaches to inhibit ...

In clinical practice, low-hormone receptor positive (low HR+) tumors are classified in the luminal subtype, although they exhibit aggressive features and poor prognosis. Information regarding the prognosis of patients with breast cancer following treatment with optimal endocrine therapy and neoadjuvant chemotherapy (NAC) is currently ...

In conclusion, Abdominal DTs were prone to occur in patients with FAP with a history of abdominal surgery. Mutations in the APC, CTNNB1 and MUTYH genes were detected in patients with DTs. To the best of our knowledge, this is the first study of abdominal DT occurrence in patients with MUTYH-associated FAP. The prognosis of DT associated with FAP may be worse compared with that of sporadic DT. PMID: 31807167 [PubMed]

It is well established that autoimmune diseases, atopic conditions and asthma affect adult females more frequently than adult males. This discrepancy typically develops after childhood and affects females differently depending on their life cycle. As children, males have higher total and allergen specific IgE levels than females and are more likely to suffer from atopic disease and asthma than girls. However, as adults, this prevalence reverses and females are more likely to develop atopic conditions such as food allergies, atopic dermatitis, urticaria, angioedema and asthma.
