Abstract
BACKGROUND Asthma is one of the most common chronic respiratory diseases with inflammatory involvement and has a high burden worldwide. This study aimed to determine the effect of Thymus vulgaris (TV) on cough in children between 5 and 12 years old with mild to moderate asthma exacerbation. METHODS In this randomized, triple-blind clinical trial, 60 children between the ages of 5 and 12 with asthma exacerbations were randomly divided into two groups. The intervention group (n = 30) was given TV powder at a dose of 20 mg/kg every 8 hours, prepared as syrup, along with routine medical treatment for a week, and the control group (n = 30) received only routine medical treatment with placebo syrup. At the end of the week, clinical and laboratory symptoms, and spirometry data were re-recorded for both groups. Finally, the recorded factors were compared and statistically analyzed. RESULTS The results showed that after the intervention, activity-induced cough reduced, and difference was statistically significant between the two groups (p = 0.042), but the reduction in wheezing and breathlessness had no statistically significant difference. Spirometry data showed a significant difference in forced expiratory volume in 1 second (FEV1) between the two groups after intervention (p = 0.048), but this difference was not significant in FEV1/FVC (forced vital capacity), peak expiratory flow (PEF), and forced expiratory flow at 25-75% of the vital capacity (FEF25-75%). CONCLUSION The results show that TV syrup may be useful as an adjuvant treatment in children with asthma exacerbations.

Abstract
The recombination activating genes, including RAG1 and RAG2, are essential for V(D)J somatic recombination in lymphocytes. Leaky severe combined immunodeficiency disorder (SCID) is characterized by normal or intermediate T cells and normal to absent B cells associated with partial T cell and B cell dysfunction. We present a newly found RAG1 deficiency in a 21-year-old boy with leaky SCID. Immunoglobulin levels, flow cytometry, and whole exome sequencing (WES) were evaluated. Flow cytometric analysis revealed a decreased number of CD3+, CD4+, and CD8+ T cells, and B cells whereas NK cell counts were normal. Immunoglobulin levels were also decreased. The WES revealed a newly found homozygous mutation of RAG1 gene (NM_000448: exon 2: c.C2275T). Atypical features, including leukopenia, candidiasis, and low lymphocyte counts in patients with late-onset combined immunodeficiency disorders (CID) such as leaky SCID due to RAG1 deficiency may result in misdiagnosis and inadequate therapy instead of adopting the curative hematopoietic stem cell transplantation in these patients.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disease in which numerous cells and mediators affect inflammatory conditions and disease severity. To compare the serum levels of adiponectin, vitamin D, copper, and zinc in patients with RA and to investigate the relationship between these parameters and RA severity. Ninety patients with RA and 30 healthy controls participated in this cross-sectional case-control study between November 2016 and April 2017; according to the ACR/EULAR criteria for RA. Serum levels of adiponectin were determined by ELISA; copper and zinc by colorimetric spectrophotometry; and vitamin D by HPLC. Kruskal-Wallis and Spearman tests were performed using SPSS software and data were depicted by GraphPad Prism software. Compared with healthy controls, the serum level of adiponectin was significantly increased, whereas vitamin D was significantly decreased in patients with RA. Adiponectin and vitamin D levels were inversely correlated in RA subgroups (P < 0.001, r = - 0.410). Adiponectin and vitamin D correlated with RA severity. Furthermore, no significant difference was found in copper and zinc levels between RA groups and controls. The definitive roles of adiponectin, vitamin D, copper, and zinc are not completely determined in RA development. Based on disease activity, these parameters can modulate inflammatory conditions, thus they have the potential to be used as promising therapeutic biomarkers to follow up the severity of disease, as well as the progression and treatment success in patients with RA.

Frequency of CD4 + and CD8 + T cells in Iranian chronic rhinosinusitis patients. Allergy Asthma Clin Immunol 2018; 14:47. [PMID: 30002685 PMCID: PMC6034261 DOI: 10.1186/s13223-018-0270-9] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2017] [Accepted: 06/14/2018] [Indexed: 12/16/2022] Open
Abstract
Background Chronic Rhinosinusitis (CRS) is a persistent inflammatory disease affecting paranasal sinuses. CRS is categorized into two distinct subgroups defined as CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). Although several immune cells are involved in the CRS pathogenesis, the role of T cells is not fully understood. The objective of the present study was to evaluate the frequency of CD4+ and CD8+ T cells and macrophages in the sinonasal mucosa of CRS patients, as well as to investigate the specific transcription factors for Th1, Th2, Th17, and Treg cells. Methods In this study, 15 healthy controls, 12 CRSsNP, and 23 CRSwNP patients participated. CD4+, CD8+, and CD68+ cells were investigated in the sinonasal tissues using immunohistochemistry. The expression of transcription factors related to Th subsets (T-bet, GATA3, Ror-γt, and FoxP3) was evaluated using real-time PCR. Furthermore, CRSwNP patients were defined as eosinophilic when eosinophils consisted of more than 10% of total inflammatory cells. The Kruskal–Wallis, Mann–Whitney, and Spearman tests were used in statistical analyses. Results The median (range) age of the studied groups was: 32 (14–67) for CRSwNP, 28 (10–43) for CRSsNP, and 27 (17–44) for controls. The number of eosinophils in CRSwNP patients was higher than two other groups, whereas neutrophils were elevated in both CRSwNP and CRSsNP groups in comparison to controls. The frequency of CD4+ and CD8+ T cells, macrophages, and total inflammatory cells were significantly increased in CRSwNP and CRSsNP patients compared with controls. The mRNA expression of GATA3 was increased in CRSwNP patients while mRNA expression of Ror-γt was elevated in CRSsNP patients. No significant difference was observed in T-bet mRNA expression among three groups. Both CRSwNP and CRSsNP patients showed decreased FoxP3 mRNA expression in comparison to controls. Conclusion The frequency of CD4+ and CD8+ T cells was elevated in CRS patients. In addition, we demonstrated Th2 dominance in CRSwNP patients and Th17 dominance in CRSsNP patients, implicating different mechanisms may underlie the disease. Better CRS classification and targeted therapeutic strategies may be achievable by determining the pattern of infiltrating inflammatory cells. Therefore, further experimental investigations on T cells are needed.
