Sarcoidosis is a genetically complex systemic inflammatory disease that affects multiple organs. We present a GWAS of a Japanese cohort (700 sarcoidosis cases and 886 controls) with replication in independent samples from Japan (931 cases and 1,042 controls) and the Czech Republic (265 cases and 264 controls). We identified three loci outside the HLA complex, CCL24, STYXL1-SRRM3, and C1orf141-IL23R, which showed genome-wide significant associations (P < 5.

Introduction: There has been an increase in the number of foreign-born tuberculosis (TB) patients residing in Japan. The purpose of this study is to clarify the clinical features of the foreign-born TB patients treated at our hospital.

Materials And Methods: This study included foreign-born TB patients treated at our hospital between 2000 and 2009.

Background: In sarcoidosis, the T helper type 1 (Th1) response tends to predominate at affected disease sites; however, whether Th1/Th2 polarization occurs in the peripheral circulation is unknown.

Methods: Fifty-two patients with sarcoidosis and 21 healthy volunteers were investigated. The concentrations of interferon-inducible protein 10 (IP-10)/CXCL10 and thymus- and activation-regulated chemokine (TARC)/CCL17 in the serum, bronchoalveolar lavage fluid (BALF) and culture supernatant were measured by an enzyme-linked immunosorbent assay.

Objective: Sarcoidosis is considered to be provocated by highly activated Th1 lymphocytes. Because interleukin 12 (IL-12) is one of the most important cytokines for promoting Th1 reaction, we tried to detect IL-12 and its ligand IL-12 receptor in sarcoidosis patients.

Patients And Methods: We measured the serum concentration of IL -12 p40 and IL-12 p70 by ELISA method with serum obtained from 60 sarcoidosis patients, and compared the serum concentration of IL-12 p40 with other clinical markers of disease activity.

A 40-year-old Japanese woman was admitted to Oita University Hospital with progressive dyspnea, consciousness disturbance and severe cytopenias. Her chest roentgenogram showed diffuse bilateral infiltrates. She was therefore forced to receive mechanical ventilation.

Recent studies have strengthened the concept that bronchial asthma and allergic rhinitis are manifestations of an inflammatory process within a continuous airway. This study was performed to compare clinical findings in asthma with or without rhinitis in Japan. Nasal symptoms were present in 99.

Aim: This investigation was undertaken to clarify the current status of steroid therapy for cardiac sarcoidosis in Japan.

Methods: A questionnaire survey was conducted throughout Japan concerning cases in which steroid therapy had been administered. Replies describing 52 cases (15 men, 37 women; mean age +/- SD, 59.

Questionnaires were sent to 46 hospitals of all over Japan in order to obtain the clinical data on sarcoidosis patients who were treated with oral corticosteroids. The number of female patients was greater than that of male patients (1.5:1), and the average age was 44.

Article Synopsis
  • TARC (Thymus- and activation-regulated chemokine) is a chemokine that attracts Th2 cells, which play a role in immune responses, particularly in eosinophilic pneumonia.
  • In a study, TARC levels were found to be significantly higher in the bronchoalveolar lavage (BAL) fluid of eosinophilic pneumonia patients compared to those with other lung diseases or healthy controls.
  • There was a strong correlation between TARC levels and Th2 cytokines like IL-5 and IL-13, suggesting that TARC may actively recruit these cells to the lungs, indicating its involvement in the development of eosinophilic pneumonia.
