Abstract
:
The growing interest in the new role of vitamin D, particularly as an immunomodulatory
factor, has spurred basic research and the development of clinical trials to better understand the
influence of supplementation on various diseases. Vitamin D is an important nutrient factor in human
health due to its role in calcium metabolism regulation, cellular growth, differentiation and its
fundamental discovered activity in immune functions. It has influenced different diseases,
particularly inflammatory and autoimmune diseases, through immune response regulation,
modulating innate and adaptive immunity.
:
The aim of this review was to explore the role of vitamin D in the main respiratory diseases in
children such as asthma, chronic rhinosinusitis, cystic fibrosis and recurrent respiratory infections.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:E3020. [PMID: 31438516 PMCID: PMC6747229 DOI: 10.3390/ijerph16173020] [Citation(s) in RCA: 60] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Revised: 08/15/2019] [Accepted: 08/19/2019] [Indexed: 12/31/2022]
Abstract
Observational studies and randomised controlled studies suggest that vitamin D plays a role in the prevention of acute respiratory tract infection (ARTI); however, findings are inconsistent and the optimal serum 25-hydroxyvitamin D (25(OH)D) concentration remains unclear. To review the link between 25(OH)D concentration and ARTI, we searched PubMed and EMBASE databases to identify observational studies reporting the association between 25(OH)D concentration and risk or severity of ARTI. We used random-effects meta-analysis to pool findings across studies. Twenty-four studies were included in the review, 14 were included in the meta-analysis of ARTI risk and five in the meta-analysis of severity. Serum 25(OH)D concentration was inversely associated with risk and severity of ARTI; pooled odds ratios (95% confidence interval) were 1.83 (1.42-2.37) and 2.46 (1.65-3.66), respectively, comparing the lowest with the highest 25(OH)D category. For each 10 nmol/L decrease in 25(OH)D concentration, the odds of ARTI increased by 1.02 (0.97-1.07). This was a non-linear trend, with the sharpest increase in risk of ARTI occurring at 25(OH)D concentration < 37.5 nmol/L. In conclusion, there is an inverse non-linear association between 25(OH)D concentration and ARTI.

Abstract
OBJECTIVES Chronic rhinosinusitis (CRS) is a disease that represents a challenging therapeutic problem. Vitamin D and its receptors (VDR) are involved in the regulation of the immune system and may play role in CRS. Objectives of this study were to assess the relationships between the total concentration of vitamin D (25VD3) in sera, vitamin D receptor (VDR) expression, 1α-hydroxylase expression, and clinical data, including age, gender, Sino-Nasal Outcome Test (SNOT-22), computerized tomography (CT) scan, allergy status, and vitamin D supplementation in CRS patients with (CRSwNP) and without nasal polyps (CRSsNP), and in a control group. METHODS The studied group comprised 52 patients with CRS without nasal polyps (sNP), 55 with CRS with nasal polyps (wNP), and 59 in the control group. The endpoints were determined by appropriate methods. We conducted immunohistochemical staining of gathered tissue from the ostiomeatal complex for determination of VDR and 1α-hydroxylase. Analytical results were compared with clinical data as already noted. RESULTS A decrease in VDR nuclear staining occurred in CRS patients as compared to controls. Insignificant differences were observed in 1α-hydroxylase, expression in all studied groups, while VDR and cytochrome CYP27B1 protein expression (1α-hydroxylase) correlated with clinical data. CONCLUSIONS The data provide evidence that indicates that vitamin D and its receptor and enzymes may play a role in CRS.

Abstract
Vitamin D concentrations corresponding to 75 nmol/L 25(OH)D have been associated with maintained muscle function, growth and regeneration, optimal bone health and immunology in athletes. The objective of this study was to investigate the prevalence and predictors of insufficient 25(OH)D concentrations in athletes. Six hundred three Swiss athletes were assessed. 25(OH)D was analysed by high-performance liquid chromatography (HPLC). A standardized questionnaire was used to gather information about potential predictors for 25(OH)D concentrations; 50.5% showed insufficient 25(OH)D concentrations. Differences in predicted probability of insufficient 25(OH)D were found for those vitamin D supplemented (42%) versus not supplemented (52%), in those performing indoor (58%) versus outdoor sports (43%), and during the sun-deprived seasons of fall (49%), winter (70%) and spring (57%) compared with summer (17%). Higher BMI z-scores and age were associated with higher 25(OH)D concentrations. In conclusion, insufficient 25(OH)D concentrations were common among athletes especially at a younger age, among those not supplemented, in athletes who trained indoors, and during the sun-deprived seasons. Because the prevalence of insufficient 25(OH)D concentrations in this study was high, regular supplementation in athletes may be indicated, except perhaps during the summer season. Further research is needed to determine which 25(OH)D concentrations lead to optimal health and performance in athletes.

Dietary vitamin D3 deficiency exacerbates sinonasal inflammation and alters local 25(OH)D3 metabolism. PLoS One 2017; 12:e0186374. [PMID: 29045457 PMCID: PMC5646812 DOI: 10.1371/journal.pone.0186374] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2017] [Accepted: 09/30/2017] [Indexed: 12/21/2022] Open
Abstract
RATIONALE Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) have been shown to be vitamin D3 (VD3) deficient, which is associated with more severe disease and increased polyp size. To gain mechanistic insights into these observational studies, we examined the impact of VD3 deficiency on inflammation and VD3 metabolism in an Aspergillus fumigatus (Af) mouse model of chronic rhinosinusitis (Af-CRS). METHODS Balb/c mice were fed control or VD3 deficient diet for 4 weeks. Mice were then sensitized with intraperitoneal Af, and one week later given Af intranasally every three days for four weeks while being maintained on control or VD3 deficient diet. Airway function, sinonasal immune cell infiltrate and sinonasal VD3 metabolism profiles were then examined. RESULTS Mice with VD3 deficiency had increased Penh and sRaw values as compared to controls as well as exacerbated changes in sRaw when coupled with Af-CRS. As compared to controls, VD3 deficient and Af-CRS mice had reduced sinonasal 1α-hydroxylase and the active VD3 metabolite, 1,25(OH)2D3. Differential analysis of nasal lavage samples showed that VD3 deficiency alone and in combination with Af-CRS profoundly upregulated eosinophil, neutrophil and lymphocyte numbers. VD3 deficiency exacerbated increases in monocyte-derived dendritic cell (DC) associated with Af-CRS. Conversely, T-regulatory cells were decreased in both Af-CRS mice and VD3 deficient mice, though coupling VD3 deficiency with Af-CRS did not exacerbate CD4 or T-regulatory cells numbers. Lastly, VD3 deficiency had a modifying or exacerbating impact on nasal lavage levels of IFN-γ, IL-6, IL-10 and TNF-α, but had no impact on IL-17A. CONCLUSIONS VD3 deficiency causes changes in sinonasal immunity, which in many ways mirrors the changes observed in Af-CRS mice, while selectively exacerbating inflammation. Furthermore, both VD3 deficiency and Af-CRS were associated with altered sinonasal VD3 metabolism causing reductions in local levels of the active VD3 metabolite, 1,25(OH)2D3, even with adequate circulating levels.

Evaluation of vitamin D levels in children with primary epistaxis. Int J Pediatr Otorhinolaryngol 2016; 89:97-101. [PMID: 27619037 DOI: 10.1016/j.ijporl.2016.07.037] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2016] [Revised: 07/29/2016] [Accepted: 07/30/2016] [Indexed: 01/24/2023]
Abstract
OBJECTIVE This study aimed to investigate whether there is a relationship between 25-hydroxy vitamin D [25(OH)D 3] values and incidences of primary epistaxis among children. METHODS A total of 42 cases and 55 matched controls were included in our study. The study group and control group were well matched for age and gender. Age, gender, activated partial thromboplastin time (APTT) with reference to the international normalized ratio (INR), prothrombin time (PT), and 25(OH)D 3, parathormone (PTH), alkaline phosphatase (ALP), calcium (Ca), magnesium (Mg), and phosphorus (P) values were recorded for each participant. RESULTS Serum 25(OH) D values were found to be statistically significantly (P = 0.03) lower in children with primary epistaxis than in the healthy control group. Our study also revealed that 25(OH) D values were considerably (P < 0.001) lower in the group with primary epistaxis and upper respiratory tract infections (RTI) than in the group with primary epistaxis without upper RTI. Univariate logistic regression analyses demonstrated that 25(OH)D 3 < 20 ng/ml [odds ratio (OR) 1.117, 95% confidence interval (CI) (1.019-1.225); P = 0.019] and serum albumin level [OR 3.499, 95% CI (1072-11,426); P = 0.038] ratio were significantly related to primary epistaxis. Furthermore, multivariate logistic regression analyses revealed that 25(OH)D 3 < 20 ng/ml [OR 1.141, 95% CI (1047-1242); P = 0.003] and serum albumin level [OR 3.340, 95% CI (1068-10,446); P = 0.038] ratio were significantly related to primary epistaxis. CONCLUSIONS Many studies have revealed that vitamin D is a preventive and therapeutic agent for inflammation and infection, thereby providing benefits for children with primary epistaxis. In line with this, our study suggested that a patient's vitamin D status could also be important for the prevention of childhood primary epistaxis, although further studies are required to validate our findings.
