Abstract
OBJECTIVE This study aimed to comprehensively investigate the prevalence of ABPA and AFRS, scrutinize existing diagnostic criteria and immunoassays, pinpoint their limitations, highlight ABPA as an occupational health implication, and identify suggestive measures to improve ABPA diagnosis in the context of Occupational Health Nursing and primary healthcare. DATA SOURCES The data sources such as PubMed, Health and Safety Science Abstracts, OSH Update, Medline, and Google Scholar were searched. STUDY SELECTIONS All published studies in the English language from 1990 till Oct, 2023 using Mesh terms keywords "Allergic bronchopulmonary aspergillosis," "Allergic fungal rhinosinusitis," "Signs and Symptoms," "Rapid Diagnostic Tests," "Diagnosis," "Occupational Health," "Occupational Health Nursing," "Prevalence," "Allergens" following "Boolean operators" search strategy were selected. RESULTS This review succinctly covered signs, symptoms, and prevalence data concerning ABPA and AFRS. It briefly discussed existing diagnostic criteria and immunoassays, highlighted factors influencing the assay's variability, and underscored the role and scope of specific allergens toward improved, simple, and early ABPA diagnosis. ABPA as a neglected occupational health concern was emphasized, and the importance of RDTs in the context of healthcare professionals and OHNs was stated. Finally, this study suggested analyzing the impact of compromised post-pandemic immune status and the use of immunosuppressive drugs on ABPA prevalence among vulnerable communities and occupations. CONCLUSION To conclude, global and Indian ABPA and AFRS prevalence data, factors influencing existing assay variability, and the scope of improvement in RDTs for ABPA diagnosis in the background of primary healthcare professionals and OHNs were addressed.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA), a severe inflammatory respiratory disease, is caused by a hypersensitivity reaction to the colonization of the airways with Aspergillus fumigatus. It is most often described in patients with asthma or cystic fibrosis. The diagnosis of ABPA is based on a combination of clinical, radiological, and immunological findings that have been included in different diagnostic criteria over the years. In this paper, we review the biomarkers included in these diagnostic criteria and novel research biomarkers that may be used in the diagnosis and treatment follow-up of ABPA in cystic fibrosis.

Abstract
INTRODUCTION Infections are becoming more difficult to treat, at least partly on account of microbes that produce biofilms. Reports suggest that decreased levels of antimicrobial peptides like cathelicidin, elevated levels of inflammatory cytokines, and biofilm formation are all associated with vitamin D deficiency, making vitamin D - deficient individuals more susceptible to infection. Infections attributable to biofilm-producing microbes can be managed by adjuvant therapy with vitamin D because of its immunomodulatory role, particularly because of the ability of vitamin D-pathway to induce the antimicrobial peptides like cathelicidin and decrease proinflammatory cytokines. AREAS COVERED This narrative review covers biofilm formation, infections associated with biofilm due to vitamin D deficiency, putative role of vitamin D in host protection and the effect of vitamin D supplementation in biofilm-associated infections. A comprehensive literature search in PubMed and Google Scholar utilizing suitable keywords at multiple time points extracted relevant articles. EXPERT OPINION Although vitamin D deficiency has been associated with infections by biofilm producing microbes, comprehensive clinical trials in various ethnicities are required to understand the likely relationships between vitamin D receptor gene expression, cathelicidin levels, and infection outcome. Current evidence hypothesizes that maintaining normal vitamin D level can help prevent and treat these infections.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is an inflammatory disease caused by immunologic reactions initiated against Aspergillus fumigatus colonizing the airways of patients with asthma and cystic fibrosis. The common manifestations include treatment-resistant asthma, transient and fleeting pulmonary opacities and bronchiectasis. It is believed that globally there are about five million cases of ABPA, with India alone accounting for about 1.4 million cases. The occurrence of ABPA among asthmatic patients in special clinics may be as high as 13 per cent. Thus, a high degree of suspicion for ABPA should be entertained while treating a patient with bronchial asthma, particularly in specialized clinics. Early diagnosis and appropriate treatment can delay (or even prevent) the onset of bronchiectasis, which suggests that all patients of bronchial asthma should be screened for ABPA, especially in chest clinics. The current review summarizes the recent advances in the pathogenesis, diagnosis and management of ABPA.

Prevalence of Vitamin D Deficiency in Treatment-Naïve Subjects with Chronic Pulmonary Aspergillosis. J Fungi (Basel) 2020; 6:jof6040202. [PMID: 33019741 PMCID: PMC7712853 DOI: 10.3390/jof6040202] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 09/14/2020] [Accepted: 09/15/2020] [Indexed: 12/30/2022] Open
Abstract
The association of vitamin D deficiency in the pathogenesis of invasive and allergic pulmonary aspergillosis is known. Whether vitamin D deficiency is prevalent in chronic pulmonary aspergillosis (CPA) remains unknown. We evaluated the prevalence of vitamin D deficiency in subjects with CPA. We compared the clinicoradiological features, microbiology, the immunological response, and the severity of CPA in those with or without vitamin D deficiency. We measured plasma vitamin D levels in 230 consecutive treatment-naïve subjects with CPA and 78 controls (28 with prior tuberculosis (TB); 50 healthy controls). We defined vitamin D deficiency as 25(OH)D3 level <20 ng/mL. The mean (95% confidence intervals (CI)) levels of plasma vitamin D levels were 19.5 (17.6–21.4), 18.6 (13.9–23.3), and 15.3 (12.6–17.9) ng/mL in subjects with CPA, diseased controls, and healthy controls, respectively; and the levels were not different between the groups. The prevalence of vitamin D deficiency in subjects with CPA was 65% (n = 150) and was also not different between healthy (70%) or diseased (61%) controls. We did not find any difference in the clinicoradiological features, microbiology, immunological response, and severity of CPA between vitamin D sufficient and deficient groups. The prevalence of vitamin D deficiency is high in subjects with CPA, albeit similar to controls. Vitamin D deficiency does not affect the disease severity in subjects with CPA.

Abstract
Vitamin D is one of the indispensable nutrients of human body. When vitamin D is deficient, it can cause a series of related diseases, such as respiratory tract infection. The regulatory role of vitamin D in inflammatory immune response and defense has attracted more and more attention. However, few studies have shown that vitamin D regulates inflammation and autophagy in Aspergillus fumigatus infected lungs. In this study, we will explain the mechanism of vitamin D regulating inflammation and autophagy in Aspergillus fumigatus infected lungs. METHODS Different concentrations of Aspergillus fumigatus spores were injected into mice with deficien diets (VitD-) or sufficient vitamin D (VitD + ) , and the survival rates were recorded. Then, the weight changes of rats were measured every other time. At the same time, a gauze was used to filter the lapped lung tissue to get the pulmonary spores and measured the amount of the spores. The mice with the same concentration of Aspergillus fumigatus infected were cut off and the lung tissue for pathological examination in the deficien diets (VitD-) group or sufficient vitamin D (VitD + ) group. Moreover, the expression of inflammation related factors TNF-α, IL-1β, IL-6 in lung was measured by immunohistochemical method. The expression of TNF-α, IL-1β, IL-6 in the serum of vitamin D deficiency and sufficient mice were measured by ELISA. In vitro, we obtained macrophages from healthy mice and mixed cultures of Aspergillus fumigatus spores and lung macrophages in medium with or without vitamin D. After the cells were infected with Aspergillus fumigatus spores, the expressions of NF-κB and IL-8 were detected by RT-PCR and Western blot. The RAW264.7 cells transfected with GFP-LC3BII were mixed with Aspergillus fumigatus spores, and the expression of cell fluorescence was observed by the fluorescence microscope with or without chloroquine and rapamycin , and the autophagy flow of the cells was measured by Western blot. In the RAW264.7 cells, Lentivirus transfection and SiRNA technologies were used to enhance or reduce the expression of the NF-κB gene (siNF-κB) for investgating the influence of high or low expression of NF-κB in the autophagic flow of vitamin D + or vitamin D-treated RAW264.7 cells. RESULTS The survival rate of vitamin D deficient mice infected Aspergillus fumigatus was significantly lower than that of vitamin D sufficient mice, while the number of spores, spore activity, pathological changes of lungs and inflammation in the lungs of vitamin D deficient mice were more severe than that of vitamin D sufficient mice. In vitro cell experiments, when cell was stimulated with vitamin D, the expressions of NF-κB and IL-8 in cells were lower. The autophagic flux and TNF-α, IL-1β, IL-6 and LC3BII in vitamin D group were significantly lower than those in vitamin D deficiency group. CONCLUSIONS Vitamin D deficiency can aggravate the inflammatory damage in the lungs of Aspergillus fumigatus. When the body is sufficient in vitamin D, if the lungs infect Aspergillus fumigatus spores, the body may resist the infection of Aspergillus fumigatus by reducing the expression of NF-κB, inflammatory factors and autophagy.

Abstract
Vitamin D has been demonstrated to have an immunomodulatory role in cystic fibrosis with allergic bronchopulmonary aspergillosis (ABPA). Herein, we evaluate supplemental vitamin D in acute-stage ABPA complicating asthma. Thirty subjects were randomised to receive either prednisolone (n = 15, control) or prednisolone and oral vitamin D (n = 15, intervention arm). Serum vitamin D levels were significantly higher in the intervention versus the control arm, following therapy. The mean decline in total IgE at 2 months (primary outcome) was 10% higher in the intervention arm than the control arm; however, this was not statistically significant (48.6% vs 38.1%, P = 0.27). The percentage decline in total IgE after 4 and 6 months of randomisation was also similar in the two arms. There was no difference in asthma exacerbations (0 vs 2, intervention vs control; P = 0.16). No ABPA exacerbation occurred in either arm. The other outcomes including the Th2 (IL-4, IL-6 and IL-10) and Th17 (IL-17) cytokine levels were similar in the two groups. None of the participants experienced hypervitaminosis D. There was no significant improvement in the clinical or immunological outcomes following vitamin D supplementation. A larger trial is required to ascertain the role of vitamin D in ABPA complicating asthma [Clinicaltrials.gov: NCT03133299].

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is a pulmonary disease caused by Aspergillus induced hypersensitivity. It usually occurs in immunocompetent but susceptible patients with bronchial asthma and cystic fibrosis. If ABPA goes undiagnosed and untreated, it may progress to bronchiectasis and/or pulmonary fibrosis with significant morbidity and mortality. ABPA is a well-recognized entity in adults; however, there is lack of literature in children. The aim of the present review is to summarize pathophysiology, diagnostic criteria, clinical features, and treatment of ABPA with emphasis on the pediatric population. A literature search was undertaken through PubMed till April 30, 2018, with keywords “ABPA or allergic bronchopulmonary aspergillosis” with limitation to “title.” The relevant published articles related to ABPA in pediatric population were included for the review. The ABPA is very well studied in adults. Recently, it is increasingly being recognized in children. There is lack of separate diagnostic criteria of ABPA for children. Although there are no trials regarding treatment of ABPA in children, steroids and itraconazole are the mainstay of therapy based on studies in adults and observational studies in children. Omalizumab is upcoming therapy, especially in refractory ABPA cases. There is a need to develop the pediatric-specific cutoffs for diagnostic criteria in ABPA. Well-designed trials are required to determine appropriate treatment regimen in children.
