RESUMEN

Allergic bronchopulmonary aspergillosis (ABPA) is a complex immunological disorder complicating asthma. Uncommonly, ABPA presents without underlying asthma. Herein, we describe the outcomes of ABPA with and without asthma. Of the 530 subjects (median follow-up, 39 months), 37 (7%) were ABPA sans asthma. Bronchiectasis was more frequent (97.3% vs. 83.2%, P = .02), and the lung function was significantly better in ABPA sans asthma. The incidence-rate of ABPA exacerbation was higher in those with asthma than without (112 vs. 242 per 1000 person-years, P = .0001). ABPA sans asthma appears to be a distinct subset of ABPA, with a better lung function and fewer exacerbations.

RESUMEN

BACKGROUND: Fungal infections are rarely reported as a complication of bronchial thermoplasty (BT) in patients without immunosuppressive comorbidity. CASE PRESENTATION: A 19-year-old woman college student was admitted to our hospital owing to uncontrolled severe asthma despite using the maximum dose of steroid inhalation. She experienced asthmatic attacks more frequently while cheerleading, which is an extracurricular activity. She received BT because she wanted to continue cheerleading. After the second BT session, she developed more sputum and cough. During the third session, white secretion and saccular bronchodilation appeared in the left lower bronchus. Aspergillus fumigatus was detected in the culture of the bronchial lavage sample, and saccular bronchodilation in the affected bronchus was observed on computed tomography (CT). Five months after the start of oral itraconazole, her subjective symptoms as well as her CT findings improved. Her asthma condition improved enough for the patient to continue cheerleading without exacerbation. CONCLUSIONS: It is necessary to consider the possibility of respiratory tract infections including fungal infections after BT. Detailed observations of the entire bronchus and sample collection for microbial culture are highly recommended.

RESUMEN

OBJECTIVES: Allergic bronchopulmonary aspergillosis (ABPA) can accelerate lung function decline in patients with cystic fibrosis (CF). Antifungal medication can be used in addition to systemic corticosteroid treatment. PATIENTS AND METHODS: We evaluated Aspergillus-specific IgE and the use of therapeutic drug monitoring of triazoles in a retrospective analysis of 32 patients. RESULTS: There was a significant reduction in Aspergillus IgE with posaconazole but not with other triazoles (P = 0.026). Aspergillus IgE levels were inversely correlated with the therapeutic drug level of posaconazole. CONCLUSIONS: These data suggest that posaconazole is better than comparator azoles at decreasing serological response to Aspergillus and that this response was better with therapeutic levels of posaconazole.

RESUMEN

Allergic bronchopulmonary aspergillosis is an immunologic pulmonary disorder caused by hypersensitivity to Aspergillus fumigatus. This disorder is most commonly seen in patients with poorly controlled asthma and cystic fibrosis. It is rarely reported in chronic granulomatous disease patients; however, there are no cases reported with hematopoietic stem cell transplantation in the English literature. Herein, we report a patient with chronic granulomatous disease who had hematopoietic stem cell transplantation and subsequently developed allergic bronchopulmonary aspergillosis.

RESUMEN

Allergic bronchopulmonary aspergillosis (ABPA) occurs in patients with asthma or cystic fibrosis, and results in pulmonary infiltrates, tenacious mucus plugs that harbor hyphae of Aspergillus fumigatus, elevations of total serum immunoglobulin E concentration and peripheral blood and sputum eosinophilia. Bronchiectasis is an irreversible complication of ABPA. The key to early diagnosis is to consider ABPA in anyone with asthma or cystic fibrosis and with a positive skin test result for Aspergillus, and/or recurrent infiltrates on radiographs. The differential diagnosis for ABPA in patients with asthma includes diseases in which there is an overlap of asthma, peripheral blood eosinophilia, and radiographic infiltrates. Examples include chronic eosinophilic pneumonia, Churg-Strauss syndrome, drug-induced pulmonary infiltrates, infection with a parasite, asthma with atelectasis, and lymphoma. Mucus plugging that causes a "tree in bud" pattern on computerized tomography examination of the lungs may be from ABPA or other conditions, such as nontuberculous (atypical) mycobacteria (Mycobacteria avium-Mycobacteria intracellulare complex). Prednisone is indicated to clear pulmonary infiltrates, and a usual course is for 3 months. Itraconazole and voriconazole are adjunctive, and drug-drug interactions must be considered because azoles decrease elimination of various medications. Although not familial in most patients, presentation of Aspergillus fumigatus f1 (Asp f1) antigen is restricted to specific major histocompatibility complex (MHC) class II molecules, Human Leukocyte Antigen-DR2 (HLA-DR2), and HLA-DR5. There is an increased number of CD4+ T-helper type 2 lymphocytes in bronchoalveolar lavage, and A. fumigatus can serve as a growth factor of eosinophils potentiating the effects of interleukin (IL) 3, IL-5, and Granulocyte-colony stimulating factor (G-CSF). Eosinophils interact directly with A. fumigatus spores and generate extracellular traps, which can injure the bronchial epithelium.

RESUMEN

BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) is a major complication in cystic fibrosis (CF) patients. Risk factors for ABPA and clinical deterioration in CF patients, negative for Pseudomonas aeruginosa (Pa), were explored. METHODS: We performed a retrospective case-control study in 73 Pa-negative patients. Each patient was matched with 2 controls for age, gender, pancreas sufficiency, DeltaF508 mutation (homozygous or heterozygous), and Pa colonization. RESULTS: Median FEV1 at the year of diagnosis (index year) was significantly lower in patients with ABPA. The median of cumulative values of FEV1 and FVC before the index year was not significantly different. After the index year, the median of cumulative data for FEV1 and FVC was significantly lower; there were significantly more hospitalization days and more IV antibiotic days compared to controls. Comparing pre- and post-index year data in patients with ABPA, significantly more hospitalization days and more IV antibiotic days were observed after the index year. During the period preceding the index year, significantly more ABPA patients were treated with rhDNase and inhaled corticosteroids. CONCLUSIONS: Bronchial damage cannot be considered as a facilitating factor for ABPA. ABPA causes a significant increase in bronchial damage. In patients with ABPA, further bronchial damage can be controlled by an increase in hospitalization days and use of IV antibiotics. rhDNase and inhaled corticosteroids were associated with the development of ABPA.

RESUMEN

BACKGROUND: Cystic fibrosis is an autosomal recessive multisystem disorder with an approximate prevalence of 1 in 3500 live births. Allergic bronchopulmonary aspergillosis is a lung disease caused by aspergillus-induced hypersensitivity with a prevalence of 2% to 15% in people with cystic fibrosis. The mainstay of treatment includes corticosteroids and itraconazole. The treatment with corticosteroids for prolonged periods of time, or repeatedly for exacerbations of allergic bronchopulmonary aspergillosis, may lead to many adverse effects. The monoclonal anti-IgE antibody, omalizumab, has improved asthma control in severely allergic asthmatics. The drug is given as a subcutaneous injection every two to four weeks. Since allergic bronchopulmonary aspergillosis is also a condition resulting from hypersensitivity to specific allergens, as in asthma, it may be a candidate for therapy using anti-IgE antibodies. Therefore, anti-IgE therapy, using agents like omalizumab, may be a potential therapy for allergic bronchopulmonary aspergillosis in people with cystic fibrosis. This is an updated version of the review. OBJECTIVES: To evaluate the efficacy and adverse effects of anti-IgE therapy for allergic bronchopulmonary aspergillosis in people with cystic fibrosis. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews. Last search: 29 September 2017.We searched two ongoing trial registries (Clinicaltrials.gov and the WHO trials platform). Date of latest search: 24 January 2018. SELECTION CRITERIA: Randomized and quasi-randomized controlled trials comparing anti-IgE therapy to placebo or other therapies for allergic bronchopulmonary aspergillosis in people with cystic fibrosis. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed the risk of bias in the included study. They planned to perform data analysis using Review Manager. MAIN RESULTS: Only one study enrolling 14 participants was eligible for inclusion in the review. The double-blind study compared a daily dose of 600 mg omalizumab or placebo along with twice daily itraconazole and oral corticosteroids, with a maximum daily dose of 400 mg. Treatment lasted six months but the study was terminated prematurely and complete data were not available. We contacted the study investigator and were told that the study was terminated due to the inability to recruit participants into the study despite all reasonable attempts. One or more serious side effects were encountered in six out of nine (66.67%) and one out of five (20%) participants in omalizumab group and placebo group respectively. AUTHORS' CONCLUSIONS: There is lack of evidence for the efficacy and safety of anti-IgE (omalizumab) therapy in people with cystic fibrosis and allergic bronchopulmonary aspergillosis. There is a need for large prospective randomized controlled studies of anti-IgE therapy in people with cystic fibrosis and allergic bronchopulmonary aspergillosis with both clinical and laboratory outcome measures such as steroid requirement, allergic bronchopulmonary aspergillosis exacerbations and lung function.

RESUMEN

BACKGROUND: Coexistence of aspergilloma and allergic bronchopulmonary aspergillosis (ABPA) has rarely been reported. Although the treatment for ABPA includes administration of corticosteroids and antifungal agents, little is known about the treatment for coexisting aspergilloma and ABPA. Furthermore, the impact of surgical resection for aspergilloma on ABPA is not fully understood. Here, we present an interesting case of recurrent ABPA with long-term follow-up after surgical resection of aspergilloma. CASE PRESENTATION: A 53-year-old man with a medical history of tuberculosis was referred to our hospital with cough and dyspnea. Imaging revealed multiple cavitary lesions in the right upper lobe of the lung, with a fungus ball and mucoid impaction. The eosinophil count, total serum immunoglobulin E (IgE), and Aspergillus-specific IgE levels were elevated. Specimens collected on bronchoscopy revealed fungal filaments compatible with Aspergillus species. Based on these findings, a diagnosis of ABPA with concomitant aspergilloma was made. Although treatment with corticosteroids and antifungal agents was administered, the patient's respiratory symptoms persisted. Therefore, he underwent lobectomy of the right upper lobe, which resulted in a stable condition without the need for medication. Twenty-three months after discontinuation of medical treatment, his respiratory symptoms gradually worsened with a recurrence of elevated eosinophil count and total serum IgE. Imaging revealed recurrent bronchiectasis and cavities with mucoid impaction in the right lower lobe, suggesting relapse of aspergilloma and ABPA. Corticosteroids and antifungal agents were re-administered; aspergilloma improved slightly over a 5-year period, and ABPA remained well controlled with low-dose prednisolone (5 mg/day). CONCLUSIONS: We describe the long-term follow-up outcomes of a patient with concomitant ABPA and aspergilloma, who underwent surgical resection for aspergilloma. Physicians should carefully monitor patients with coexisting ABPA and aspergilloma, as the condition may relapse after remission, even despite surgical resection for aspergilloma. Additionally, surgical resection for aspergilloma could result in resolution of ABPA.

RESUMEN

AIM: To estimate the frequency of fungal sensitization and the incidence of allergic bronchopulmonary aspergillosis (ABPA) in asthmatic patients. SUBJECTS AND METHODS: A total of 140 asthmatic patients were examined. They underwent allergologic (skin tests for fungal allergens, estimation of total and fungal allergen-specific IgE levels) and mycological (microscopy and inoculation of respiratory biosubstrates) examinations. Chest computed tomography, when indicated, was done. A group of patients with ABPA and that of patients with severe asthma and fungal sensitization were identified. RESULTS: The frequency of fungal sensitization in asthmatic patients was 36%; the main allergenic fungi were Aspergillus and Alternaria. The incidence of ABPA was as high as 4% in the patients with asthma and 11% in those with severe asthma and fungal sensitization. CONCLUSION: The given current diagnostic criteria will assist practitioners to identify ABPA, to prevent its progression, and to initiate specific anti-inflammatory and antifungal therapy in due time.

RESUMEN

BACKGROUND: Sensitisation with Aspergillus fumigatus (Af) is known to be associated with severe allergic lung inflammation, but the mechanism remains to be clarified. Phosphoinositide 3-kinase (PI3K)-δ and endoplasmic reticulum (ER) stress are suggested to be involved in steroid-resistant lung inflammation. We aimed to elucidate the role of PI3K-δ and its relationship with ER stress in fungus-induced allergic lung inflammation. METHODS: Using Af-exposed in vivo and in vitro experimental systems, we examined whether PI3K-δ regulates ER stress, thereby contributing to steroid resistance in fungus-induced allergic lung inflammation. Moreover, we checked expression of an ER stress marker in lung tissues isolated from patients with allergic bronchopulmonary aspergillosis. RESULTS: Af-exposed mice showed that ER stress markers, unfolded protein response (UPR)-related proteins, phosphorylated Akt, generation of mitochondrial reactive oxygen species (mtROS), eosinophilic allergic inflammation, and airway hyperresponsiveness (AHR) were increased in the lung. Similarly, glucose-regulated protein 78 was increased in lung tissues of patients with ABPA. A PI3K-δ inhibitor reduced Af-induced increases in ER stress markers, UPR-related proteins, allergic inflammation and AHR in mice. However, dexamethasone failed to reduce Af-induced allergic inflammation, AHR and elevation of ER stress. Administration of an ER stress inhibitor or a mtROS scavenger improved Af-induced allergic inflammation. The PI3K-δ inhibitor reduced Af-induced mtROS generation and the mtROS scavenger ameliorated ER stress. In primary cultured tracheal epithelial cells, Af-induced ER stress was inhibited by blockade of PI3K-δ. CONCLUSIONS: These findings suggest that PI3K-δ regulates Af-induced steroid-resistant eosinophilic allergic lung inflammation through ER stress.

RESUMEN

Prompt diagnosis of allergic bronchopulmonary mycosis (ABPM) is an important clinical issue in preventing irreversible lung damage. Therefore, a good serological marker for the diagnosis of ABPM is desired in clinical practice. The measurement of IgE antibody to crude Aspergillus fumigatus allergen is considered the first step in screening asthmatic patients for allergic bronchopulmonary aspergillosis (ABPA). However, presence of IgE to A. fumigatus does not always indicate genuine sensitization to A. fumigatus because of cross-reactivity between crude extracts from different fungal sources. The application of molecular-based allergy diagnosis can solve this problem. The specificity of testing can be greatly improved by measuring the IgE antibody to Asp f 1 and f 2, specific allergen components for genuine A. fumigatus allergy. The problem of cross-reactivity between crude fungal extracts is also true for the identification of genuine causal fungi in each ABPM patient. Some patients with ABPM induced by fungi other than Aspergillus may be consistent with ABPA diagnostic criteria because current criteria depend on IgE/IgG reactivity to crude extracts. Accurate identification of genuine causal fungi for ABPM is of clinical importance, considering that clinical presentation, anti-fungal treatment strategies and disease prognosis can be influenced by different causal fungi. The diagnosis of causal fungi can be robustly validated by the confirmation of genuine sensitization to fungi after measuring IgE to specific allergen components, as well as repeated microbiological isolation of the fungi from their airway.

RESUMEN

BACKGROUND: The prevalence of Aspergillus sensitization (AS) and allergic bronchopulmonary aspergillosis (ABPA) in cystic fibrosis (CF) has been varyingly reported. The aim of this systematic review was to estimate the overall prevalence of AS/ABPA in CF. METHODS: We searched the PubMed and EmBase databases for studies reporting the prevalence of AS/ABPA in CF. We calculated the proportion with 95% confidence interval (CI) to assess the prevalence of AS and ABPA in the individual studies and then pooled the results using a random effects model. Statistical heterogeneity was assessed using the I2 test while publication bias was assessed using both graphical and statistical methods. RESULTS: Our search yielded 64 eligible studies. The pooled prevalence of AS was 39.1% (95% CI: 33.3-45.1) and was higher with skin test compared to specific IgE (43.8% vs. 32.8%, P = 0.002); however, the prevalence did not vary with the type of skin test used (intradermal or percutaneous). The prevalence of ABPA was 8.9% (95% CI: 7.4-10.7) and was higher in adults as compared to children (10.1% vs. 8.9%, P < 0.0001). There was a wide variation in the criteria used for diagnosing ABPA. Almost 50% (12/23) of the publications after 2004 used criteria other than the CF foundation criteria for diagnosing ABPA. There was significant statistical heterogeneity and evidence of publication bias. CONCLUSIONS: There is a high prevalence of AS and ABPA in patients with CF. Despite six decades of research, there is still a need to adopt uniform methodology and criteria for the diagnosis of AS/ABPA.

RESUMEN

The cut-off values of immunological tests employed in diagnosis of allergic bronchopulmonary aspergillosis (ABPA) have never been validated. Herein, we compare the immunological findings in patients with ABPA and asthma using receiver operating characteristic analysis. Consecutive asthmatic subjects underwent all the following investigations: Aspergillus skin test, IgE levels (total and A. fumigatus-specific), Aspergillus precipitins, eosinophil count, chest radiograph and CT chest. There were 372 subjects (179 men, mean age 35.9 years) with a mean asthma duration of 8 years. ABPA was diagnosed in 76 patients (64 bronchiectasis, 12 without bronchiectasis). ABPA was separated from asthma using the best cut-off values of total IgE, A. fumigatus IgE and total eosinophil count of 2347 IU ml(-1) , 1.91 kUA l(-1) and 507 cells per µl respectively. The sensitivity/specificity of these parameters were 87/81%; 99/87%; and, 79/76% respectively. The corresponding AUC values were 0.95, 0.90 and 0.82 respectively. The combination of these three tests at the aforementioned cut-offs provided 100% specificity. Our study provides evidence-based cut-off values of IgE (total and A. fumigatus-specific) and eosinophil counts in differentiating ABPA from asthma. As this is a single centre retrospective study, further studies from different centres are required, as these values could vary by ethnicity and environmental exposure.

RESUMEN

Allergic bronchopulmonary aspergillosis (ABPA) is an immunological pulmonary disorder caused by hypersensitivity to Aspergillus fumigatus, manifesting with poorly controlled asthma, recurrent pulmonary infiltrates and bronchiectasis. There are estimated to be in excess of four million patients affected world-wide. The importance of recognizing ABPA relates to the improvement of patient symptoms, and delay in development or prevention of bronchiectasis, one manifestation of permanent lung damage in ABPA. Environmental factors may not be the only pathogenetic factors because not all asthmatics develop ABPA despite being exposed to the same environment. Allergic bronchopulmonary aspergillosis is probably a polygenic disorder, which does not remit completely once expressed, although long-term remissions do occur. In a genetically predisposed individual, inhaled conidia of A. fumigatus germinate into hyphae with release of antigens that activate the innate and adaptive immune responses (Th2 CD4(+) T cell responses) of the lung. The International Society for Human and Animal Mycology (ISHAM) has constituted a working group on ABPA complicating asthma (www.abpaworkinggroup.org), which convened an international conference to summarize the current state of knowledge, and formulate consensus-based guidelines for diagnosis and therapy. New diagnosis and staging criteria for ABPA are proposed. Although a small number of randomized controlled trials have been conducted, long-term management remains poorly studied. Primary therapy consists of oral corticosteroids to control exacerbations, itraconazole as a steroid-sparing agent and optimized asthma therapy. Uncertainties surround the prevention and management of bronchiectasis, chronic pulmonary aspergillosis and aspergilloma as complications, concurrent rhinosinusitis and environmental control. There is need for new oral antifungal agents and immunomodulatory therapy.

RESUMEN

Allergic bronchopulmonary aspergillosis [ABPA] complicates cystic fibrosis in around 10% of teenagers. Systemic corticosteroids are the mainstay of treatment but with on-going use are associated with significant side effects prompting consideration of steroid sparing therapies. The clinical courses over ten years of two children with CF complicated by steroid dependent chronic ABPA and its successful treatment with monthly omalizumab are reported.

RESUMEN

BACKGROUND: Cystic fibrosis is an autosomal recessive multisystem disorder with an approximate prevalence of 1 in 3500 live births. Allergic bronchopulmonary aspergillosis is a lung disease caused by aspergillus-induced hypersensitivity with a prevalence of 2% to 15% in people with cystic fibrosis. The mainstay of treatment includes corticosteroids and itraconazole. The treatment with corticosteroids for prolonged periods of time, or repeatedly for exacerbations of allergic bronchopulmonary aspergillosis, may lead to many adverse effects. The monoclonal anti-IgE antibody, omalizumab, has improved asthma control in severely allergic asthmatics. The drug is given as a subcutaneous injection every two to four weeks. Since allergic bronchopulmonary aspergillosis is also a condition resulting from hypersensitivity to specific allergens, as in asthma, it may be a candidate for therapy using anti-IgE antibodies. Therefore, anti-IgE therapy, using agents like omalizumab, may be a potential therapy for allergic bronchopulmonary aspergillosis in people with cystic fibrosis. OBJECTIVES: To evaluate the efficacy and adverse effects of anti-IgE therapy for allergic bronchopulmonary aspergillosis in people with cystic fibrosis. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews. Last search: 21 January 2013.We searched the ongoing trial registry clinicaltrials.gov for any ongoing trials. Latest search for clinicaltrials.gov: 22 February 2013. SELECTION CRITERIA: Randomized and quasi-randomized controlled trials comparing anti-IgE therapy to placebo or other therapies for allergic bronchopulmonary aspergillosis in people with cystic fibrosis. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed the risk of bias in the included study. They planned to perform data analysis using Review Manager 5.1. MAIN RESULTS: Only one trial enrolling 14 patients was eligible for inclusion in the review. The study was terminated prematurely and complete data were not available. We contacted the study investigator and were told that the study was terminated due to the inability to recruit patients into the study despite all reasonable attempts. One or more serious side effects were encountered in six out of nine (66.67%) and one out of five (20%) patients in omalizumab group and placebo group respectively. AUTHORS' CONCLUSIONS: There is lack of evidence for the efficacy and safety of anti-IgE (omalizumab) therapy in patients with cystic fibrosis and allergic bronchopulmonary aspergillosis. There is a need for large prospective randomized controlled trials of anti-IgE therapy in people with cystic fibrosis and allergic bronchopulmonary aspergillosis with both clinical and laboratory outcome measures such as steroid requirement, allergic bronchopulmonary aspergillosis exacerbations and lung function.

RESUMEN

BACKGROUND: Fungal exposure is associated with particularly severe asthma. Nevertheless, the effects of anti-fungal treatments on fungus-exacerbated asthma need to be determined. OBJECTIVES: The present study aimed to compare the effects of itraconazole (ITCZ) and dexamethasone (Dex) on Aspergillus fumigatus (Af)-exacerbated preexisting Dermatophagoides farinae (Df) allergen-sensitized allergic airway inflammation. METHODS: Four groups of BALB/c mice were prepared: control, Df-sensitized plus Af-infected mice (Df-Af), and Df-Af mice treated with Dex (Df-Af-Dex) or with ITCZ (Df-Af-ITCZ). Pulmonary pathology and cytokine profiles in the airway were evaluated. In a different set of experiments, the effects of Dex on alveolar macrophage (AM) phagocytosis of Af conidia were determined in Df-sensitized mice. RESULTS: Af infection significantly increased the level of eosinophils and neutrophils in the airway of Df-sensitized mice. While Dex significantly decreased eosinophils, ITCZ significantly decreased both eosinophils and neutrophils in Df-Af mice. Dex significantly decreased IL-5, whereas ITCZ significantly reduced MIP-2 in the airway. Compared to controls, AM isolated from Df-sensitized mice had significantly reduced phagocytotic activity of Af conidia. However, Dex significantly improved phagocytotic activity of AM in Df-sensitized mice. CONCLUSIONS: The present study showed that Dex and ITCZ differently regulated Af-exacerbated allergic airway inflammation; the former inhibits eosinophilic inflammation and the latter inhibits neutrophilic as well as eosinophilic inflammation by regulating different cytokines. Additionally, Dex enhanced the phagocytotic activity of AM in allergic asthma. Thus, a combination of Dex and ITCZ might be effective for the management of fungus-exacerbated asthma.

RESUMEN

The separation of rotting garden material from general domestic waste and its collection for processing in industrial composting sites is a relatively new industry in the UK. Two cases of allergic bronchopulmonary aspergillosis and the results of health surveillance are described in a team of 28 garden waste (compost) collectors. A few cases of extrinsic allergic alveolitis due to Aspergillus fumigatus have previously been reported in compost workers. In the absence of any guidance from research and to prevent similar cases of a potentially serious illness, we advise that new starters to the job of collecting or processing compost are screened for asthma and aspergillus sensitivity, cystic fibrosis, bronchiectasis and immunodeficiency if their exposure to high levels of Aspergillus sp cannot be controlled. Annual health surveillance for these workers is also recommended.
