Takayasu arteritis (TA) is a chronic large-vessel vasculitis of unknown etiology. Human leukocyte antigen (HLA) alleles play an important role in the development of TA. Sequence specific primer-polymerase chain reaction was used to detect 10 alleles of the HLA-DQA1 gene and 13 alleles of the HLA-DQB1, -DRB1 gene. A significant increase in the frequencies of DRB1(∗)07 (Pc<0.01, OR=3.44, CI: 2.15-5.52) was observed among TA patients compared with the control group. The significantly increased frequencies of the haplotype DQA1(∗)03:01-DQB1(∗)03:01-DRB1(∗)07 (Corrected P-values<0.01) were observed in TA patients. But in the analysis of clinical manifestations, there are no significant associations with the HLA-DRB1(∗)07 allele.

Mediastinum

September 2024

Divisions of Critical Care, Pulmonary and Sleep Medicine, Department of Internal Medicine, McGovern Medical School, The University of Texas Health Science Center (UTHealth), Houston, TX, USA.

Background And Objective: There are several benign processes that affect the mediastinum with considerable morbidity that may range from reactive entities to neoplastic disorders. This review article will focus on non-neoplastic benign mediastinal diseases which include large vessel vasculitis such as Takayasu and giant cell arteritis, mediastinal granulomas, fibrosing mediastinitis and mediastinal infections. These diseases can cause significant morbidity and mortality; therefore, we aim to familiarize readers with the pathophysiology, epidemiology and diagnosis of these mediastinal diseases and provide an update on the treatment options available.

Purpose: Takayasu arteritis (TAK) is a rare form of chronic vasculitis that is common in Asian female. As TAK predominantly affects young female with a longer life expectancy than those with atherosclerotic diseases, assessing the specific long-term outcomes of TAK treatment is important. Therefore, this study aimed to evaluate the long-term outcomes and post-procedural complications of surgical and endovascular treatment for TAK.
