BACKGROUND AND METHODS: Symptomatic pulmonary aspergillosis has rarely been reported in patients with the acquired immunodeficiency syndrome (AIDS). We describe the predisposing factors, the clinical and radiologic features, and the therapeutic outcomes in 13 patients with pulmonary aspergillosis, all of whom had human immunodeficiency virus (HIV) infection and 12 of whom had AIDS.!,br,!!,br,!RESULTS: Pulmonary aspergillosis was detected a median of 25 months after the diagnosis of AIDS, usually following corticosteroid use, neutropenia, pneumonia due to other pathogens, marijuana smoking, or the use of broad-spectrum antibiotics. Two major patterns of disease were observed: invasive aspergillosis (in 10 patients) and obstructing bronchial aspergillosis (in 3). Cough and fever, the most common symptoms, tended to be insidious in onset in patients with invasive disease (median duration, 1.3 months before diagnosis). Breathlessness, cough, and chest pain predominated in the three patients with ...
Youre more likely to have an invasive type of aspergillosis if your immune system is weakened by chemotherapy and conditions such as leukemia, cancer, and AIDS.. A weakened immune system makes it more difficult to fight off infections. This type of aspergillosis invades your lung tissues and can spread to your kidneys or brain. If invasive aspergillosis goes untreated, it can cause infectious pneumonia. Infectious pneumonia can be life-threatening in people with compromised immune systems.. Invasive aspergillosis often occurs in people who already have other medical conditions, so it can be hard to separate the symptoms of invasive aspergillosis from those of the other conditions. Known symptoms of invasive aspergillosis include:. ...
Invasive mycoses represent a major cause of morbidity and mortality in patients with malignancy or undergoing hematopoietic stem cell transplantation (HSCT). Recently it has been shown that the Toll-like receptor system could play an important role in the development of invasive aspergillosis in patients receiving chemotherapy or after HSCT, and there is evidence suggesting that the involvement of Toll-like receptors during Aspergillus fumigatus infection is influenced by the immunological status of the host. The upper and lower respiratory tracts represent the most frequent locations of A. fumigatus infection in all patient categories and age groups. Among echinocandins, caspofungin has been approved for salvage therapy in patients with invasive aspergillosis, since it has been demonstrated to be well-tolerated and with a 39% response in patients with refractory infections. However, in this study as in other salvage therapy trials, the need for salvage therapy was established in the presence of
Both X-linked and autosomal recessive forms of CGD are complicated by invasive aspergillosis and there is approximately a 40% lifetime incidence of this complication in CGD. A few even rarer cases of neutrophil dysfunction complicated by invasive aspergillosis are described. Occasional instances of 2 children from one family developing invasive aspergillosis, usually related to farm exposures have been reported. Most cases present in children, 56% at #5 years and 89% at #10 years.. The clinical presentation of invasive aspergillosis in CGD is distinctive. Pneumonia is most common but osteomyelitis is much more frequent, proportionately, than in other host groups (Table). Pneumonia tends to be bilateral, slowly progressive, with little or no fever. Radiologically it usually presents with a fine nodular pattern, widespread patchy shadowing or with a chest wall abscess with underlying consolidation. If a chest wall abscess is present (Table), rib osteomyelitis is invariably present as well. ...
We describe a novel heterothallic species in Aspergillus section Fumigati, namely A. felis (neosartorya-morph) isolated from three host species with invasive aspergillosis including a human patient with chronic invasive pulmonary aspergillosis, domestic cats with invasive fungal rhinosinusitis and a dog with disseminated invasive aspergillosis. Disease in all host species was often refractory to aggressive antifungal therapeutic regimens. Four other human isolates previously reported as A. viridinutans were identified as A. felis on comparative sequence analysis of the partial β-tubulin and/or calmodulin genes. A. felis is a heterothallic mold with a fully functioning reproductive cycle, as confirmed by mating-type analysis, induction of teleomorphs within 7 to 10 days in vitro and ascospore germination. Phenotypic analyses show that A. felis can be distinguished from the related species A. viridinutans by its ability to grow at 45°C and from A. fumigatus by its inability to grow at 50°C. ...

Aspergillosis is a serious infection particularly affecting the immunodeficient host. Its co-infection with tuberculosis and cytomegalovirus has not been reported before. Embolic events are well recognized with aspergillous endocarditis and aortitis. Splenic abscess is a rare serious complication of disseminated aspergillosis and is difficult to treat. We report the first case of multiple embolic events and splenic abscess in a patient with pulmonary aspergillosis and cytomegaloviral and tuberculous co-infection, without endocarditis or aortitis. Thirty-year-old male presented with fever and non-productive cough while on glucocorticoids for glomerulonephritis. He was found to have pulmonary aspergillosis and subsequently developed bilateral lower limb and cerebral fungal emboli and fungal abscess in the spleen. He had IgM and B cell deficiency and cytomegalovirus (CMV) and tuberculous co-infections. He recovered after prolonged course of antimicrobials, splenectomy and cessation of glucocorticoid

Invasive pulmonary aspergillosis (IPA) remains a major cause for morbidity and mortality in patients (pts) with hematologic malignancies. As culture-based methods only yield results in a minority of patients, using non-culture-based methods for detection of aspergillosis in clinical specimens becomes increasingly important. Analyzing bronchoalveolar lavage (BAL) samples with polymerase chain reaction (PCR) is promising, however, the influence of current antifungal drugs on the performance of this diagnostic tool remains controversial.. The aim of the trial is to elucidate on the performance of BAL PCR under antifungal treatment.. Patients with high risk of invasive aspergillosis and lung infiltrates are sampled via BAL, the sample is analyzed for fungal DNA by Apsergillus specific PCR. Clinical data including treatment data is assessed and evaluated. ...
Isavuconazole for the treatment of invasive aspergillosis and mucormycosis: current evidence, safety, efficacy, and clinical recommendations Suganthini Krishnan Natesan,1,2 Pranatharthi H Chandrasekar1 1Division of Infectious Diseases, Department of Internal Medicine, Wayne State University, 2John D Dingell VA Medical Center, Detroit, MI, USA Abstract: The majority of invasive mold infections diagnosed in immunocompromised cancer patients include invasive aspergillosis (IA) and mucormycosis. Despite timely and effective therapy, mortality remains considerable. Antifungal agents currently available for the management of these serious infections include triazoles, polyenes, and echinocandins. Until recently, posaconazole has been the only triazole with a broad spectrum of anti-mold activity against both Aspergillus sp. and mucorales. Other clinically available triazoles voriconazole and itraconazole, with poor activity against mucorales, have significant drug interactions in addition to a side effect
Males and females of greater than 12 years of age with any of the following conditions:. Allogeneic or autologous bone marrow/ peripheral stem cell transplant.. Hematological malignancy (including lymphoma).. Aplastic anemia and myelodysplastic syndromes (currently on immunosuppressive treatment).. Solid organ transplantation.. Solid organ malignancy (after cytotoxic chemotherapy).. HIV infection/AIDS.. High dose prolonged corticosteroid therapy (greater than or equal to 20 mg daily of prednisone or equivalent for greater than 3 weeks) or prolonged therapy with other immunosuppressive agents (e.g., azathioprine, methotrexate).. WITH a diagnosis of definite or probable acute invasive aspergillosis.. The fungal infection at baseline should represent a new episode of acute invasive aspergillosis. Any course of systemic treatment with amphotericin B (conventional or lipid formulation) or itraconazole should have been completed at least 8 weeks prior to study entry.. Signed informed consent must be ...
A new animal model of invasive aspergillosis is described in which female New Zealand White rabbits were immunosuppressed with corticosteroids and cyclophosphamide and were given an intratracheal inoculation of 4 × 104 conidia of Aspergillus fumigatus. Thirteen of 15 animals survived during a 10-day-period of observation. Most had clinical signs of a respiratory infection (dyspnoea) and at autopsy there was macroscopic and microscopic evidence of invasive pulmonary aspergillosis. Six control animals (infected but not immunosuppressed) showed no such signs. The extent of hyphal invasion was assessed histologically and quantified by calculating the number of colony forming units (c.f.u.) g-1 of tissue: in the experimental group the mean c.f.u. value for the lungs was 1·25 × 103compared to 73·3 c.f.u. g-1 of lung for the control group (P=0·003). The infection was also quantified by a whole lung chitin assay: in the experimental group the mean chitin content (expressed as a glucosamine equivalent) was
Invasive aspergillosis is a severe infection of immunocompromised hosts, caused by the inhalation of the spores of the ubiquitous environmental molds of the Aspergillus genus. The innate immune response in this infection entails a series of complex and inter-related interactions between multiple recruited and resident cell populations with each other and with the fungal cell; in particular, iron is critical for fungal growth. A computational model of invasive aspergillosis is presented here; the model can be used as a rational hypothesis-generating tool to investigate host responses to this infection. Using a combination of laboratory data and published literature, an in silico model of a section of lung tissue was generated that includes an alveolar duct, adjacent capillaries, and surrounding lung parenchyma. The three-dimensional agent-based model integrates temporal events in fungal cells, epithelial cells, monocytes, and neutrophils after inhalation of spores with cellular dynamics at the tissue
Infection with the fungus Aspergillus, seen especially in people with a deficient immune system. The clinical features of aspergillosis can include invasive lung infection and disseminated disease, usually with fever, cough, spitting up blood, and chest pain. Aspergillosis may mimic asthma with cough and inspiratory stridor (noise on breathing in) or sinusitis with fever, localized pain. Aspergillosis is due most often to Aspergillus fumigatus or Aspergillus flavus and less commonly A. niger, A. terreus, or A. nidulans. These fungi frequently colonize the upper respiratory tract and are among the most common in the environment. At elevated risk for aspergillosis are people with a blood malignancy or lymphoma, anyone who has had a transplant or is taking high-dose corticosteroids and, rarely, people with HIV infection. Diagnosis may be difficult. It usually requires a biopsy. The advent of effective, less toxic antifungal drugs (such as itraconazole) has improved therapy. The prognosis (outlook) ...
The mortality of clinical Aspergillus infections necessitates consideration of the utility of a vaccine. We have found that Saccharomyces species can act as a protective vaccine against a lethal systemic Aspergillus infection, and describe experiments optimizing a subcutaneous regimen with killed yeast. Three injections of 2.5 mg given a week apart, 2 weeks prior to challenge, consistently, significantly, provided survival protection and reduction of infection in organs in survivors. The protection was independent of the strain of Saccharomyces, and possibly even the species, and could be demonstrated in several inbred (including C′-deficient) and outbred mouse strains. The protective moiety(ies) appeared to reside in the cell wall and was resistant to 100 °C, but not to protease or formalin. Alum potentiated the protection. The protection was comparable or superior to that of several Aspergillus-specific preparations described in the literature. Other studies have indicated that heat-killed

Other species of domestic animals. Spontaneous aspergillosis in domestic rabbits has been reported by Schöppler (1919) and Höppli (1923), whilst Ainsworth & Austwick (1955a) have recorded the disease in guinea-pigs. Apparently no authentic case of pulmonary aspergillosis has been found in the dog for the main records from this animal by Gotti (1871) and Stazzi (1905) are of nasal and auricular fungal infection due to a variety of fungi. A case in a cat has been described by Sautter et al. (1955) and Ainsworth & Austwick (1955a) briefly report the occurrence of a large aspergillotic nodule in the udder of a goat which was associated with chronic mastitis. Wild animals. As in birds captive wild mammals have provided several examples of aspergillosis. Dobberstein (1936) reported a case of meningeal infection in an elk in the Berlin zoo, whilst Rewell & Ainsworth (1947) showed how the respiratory passages of an American bison at the London zoo were found on post-mortem examination to be lined with ...
Aspergillosis infection of central nervous system (CNS) is rare and fatal. Diagnosis of invasive aspergillosis remains difficult. Aspergillosis of CNS can be an acute, subacute, or chronic onset, and the longest course of the disease was currently reported to be 4 years. Here, we report a case with recurrent headache over 20 years. A 54-year-old man was admitted to our neurological disease ward due to intermittent throbbing headache lasting for more than 20 years that had grown notably worse over the past week. The headache was localized to the side of his head blown by a cold wind. He also experienced nausea and vomiting when the headache became severe. The headache usually lasted for 3-4 h after he was blown by the cold wind, though he had no fever. The neurological examination was normal. Magnetic resonance imaging (MRI) of the brain was negative for parenchymal and meningeal lesions. However, the case had increased intracranial pressure (ICP), and elevated protein level in the cerebrospinal fluid
Background. Invasive aspergillosis (IA) is a leading cause of mortality in patients with acute leukemia. Management of IA is expensive, which makes prevention desirable. Because hospital resources are limited, prevention costs have to be compared with treatment costs and outcome.. Methods. In 269 patients treated for acute myelogenous leukemia-myelodysplastic syndrome (AML-MDS) during 2002-2007, evidence of IA was collected using high-resolution computed tomography and galactomannan measurement in bronchoalveolar lavage fluid specimens. IA was classified on the basis of updated European Organization for Research and Treatment of Cancer/Mycoses Study Group definitions. Outcome of infection was registered. Diagnostic and therapeutic IA-related costs, corrected for neutropenia duration, were comprehensively analyzed from a hospital perspective. Voriconazole treatment was given orally from day 1 if possible.. Results. A total of 80 patients developed IA; 48 (18%) had probable or proven infection, ...

Abstract BACKGROUND: Craniocerebral invasive Aspergillosis of sino-nasal origin has been reported with a very high mortality due to a peculiarly fulminant clinical course. Early diagnosis based on clinical radiological imaging may have an impact on final clinical outcome. This retrospective study focuses on characteristic MR imaging features of Aspergillosis (of sinonasal origin) in immunocompetent patients. METHODS: Medical records of patients were reviewed retrospectively during the period from 1991 to 2003 in the two tertiary care hospitals. All the patients had radiological evidence of disease in the paranasal sinuses with or without intracranial extension. Immunocompetence of patients was assessed on clinical and radiological data. MRI scans (n=20) were reviewed by both clinical neurosurgeons and neuroradiologists separately. MRI was done on 1.5 tesla scanners and both T2-weighted and T1 weighted sequences were obtained followed gadolinium enhanced images. Patients were categorized into three
There are 17 similar cases in the English literature over 33 years (table 1). Yet we have seen four cases, all whose symptoms began over a six month period between April and September 1999. In our community, there has also been a parallel increase of pulmonary aspergillosis.. All of our patients presented with a vague but persistent complaint of pain localised to one side of the head or retrobulbar area. Two had a dull pain that became sharp, whereas the other two began with sharp, stabbing pain. In all, the pain preceded the ophthalmic findings by 1-6 months and became relentless and severe. In the literature, 13 of 17 patients had an initial complaint of pain or headache (table 1).2-12. The time from onset of symptoms to diagnosis was 2-10 months in our patients. In two patients, a diagnosis of temporal arteritis was either made or entertained because of their history of pain. Cases 1 and 3 were treated with steroids, which may worsen aspergillosis infection. In the literature, four cases were ...
Author(s): Jenks, Jeffrey D; Hoenigl, Martin | Abstract: Infections caused by Aspergillus spp. remain associated with high morbidity and mortality. While mold-active antifungal prophylaxis has led to a decrease of occurrence of invasive aspergillosis (IA) in those patients most at risk for infection, breakthrough IA does occur and remains difficult to diagnose due to low sensitivities of mycological tests for IA. IA is also increasingly observed in other non-neutropenic patient groups, where clinical presentation is atypical and diagnosis remains challenging. Early and targeted systemic antifungal treatment remains the most important predictive factor for a successful outcome in immunocompromised individuals. Recent guidelines recommend voriconazole and/or isavuconazole for the primary treatment of IA, with liposomal amphotericin B being the first alternative, and posaconazole, as well as echinocandins, primarily recommended for salvage treatment. Few studies have evaluated treatment options for chronic

Early in August, Professor Denning visited Lanzhou, Hangzhou, Shanghai and Guangzhou meeting clinicians, visiting laboratories and educating physicians about the large burden of fungal disease and the opportunity for improved diagnostics. He cited one example from China of the likely number of deaths from invasive aspergillosis in COPD patients. Of the estimated 32.8 million people with COPD, nearly 12 million are admitted to hospital each year. A study in nearly 300 admissions in Guangzhou showed 3.9% to have invasive aspergillosis, and 43% died. If translated to the whole of China, 460,000 would develop invasive aspergillosis and nearly 200,000 die. These figures are based on culture from the respiratory tract, a notoriously insensitive test for this disease, suggestive of a substantial under-estimate. ...

Disseminated aspergillosis has killed many patients who were being treated with immunosuppressive agents after organ transplantation. Few cases were recognized in patients before death, and those that were discovered were in terminally ill patients, and therapy was ineffective.. Four patients infected with Aspergillus fumigatus after renal homotransplantation are described. All infections were controlled successfully with amphotericin B. Immune suppression was continued and rejection crises treated with high doses of corticoids without extension of the fungal disease. Three of the patients required open lung biopsy to establish the diagnosis and stimulate accurate and prompt therapy. One patient was treated without biopsy ...
A blood sample may be taken and sent to the laboratory to analyse whether antibodies to aspergillus are present in the blood - this test may also be called an aspergillus precipitin test. A positive result means that antibodies to the fungus have been detected. A positive test result is a useful marker for later comparisons to assess efficiency of treatment. Occasionally a false positive result may occur which is why a number of different tests are used in diagnosing aspergillosis. Sometimes markers of allergy to aspergillus are positive in the blood. A test for a particular fungal molecule sometimes found in the blood - called the galactomannan test may also be carried out on a blood sample.. In addition other tests include blood count, plasma viscosity and C-reactive protein which may indicate inflammation - such markers usually improve on treatment so a baseline level is helpful. Liver and kidney function tests are important as liver function can be abnormal on antifungal drugs. Also some ...
Review question. We planned to review the evidence about the accuracy of polymerase chain reaction (PCR) tests for diagnosing invasive aspergillosis (IA) in people with defective immune systems from medical treatment such as chemotherapy or following organ or bone marrow transplant. Background: IA is a fungal disease caused by Aspergillus, a widespread mould. Most people breathe in Aspergillus spores every day without becoming ill, however people with weakened immune systems or lung diseases are at a higher risk of developing health problems due to Aspergillus. IA causes patient afflictions that are classically defined as invasive, saprophytic or allergic. Some types of IA are mild, but some of them are very serious. IA is the most common life-threatening, opportunistic, invasive fungal infection in people whose immune systems are compromised. Without treatment, most people with IA will die as a direct result, so early diagnosis and prompt administration of appropriate antifungal treatment are ...
Culturing of tissue is currently the gold standard for the diagnosis of IA.11 This method not only yields Aspergillus spp, but further defines therapeutic options via susceptibility testing. However, the invasiveness of obtaining tissue makes culturing less desirable. In the absence of tissue specimens, bronchoalveolar lavage (BAL) fluid obtained from the upper and lower respiratory tracts can serve to establish the diagnosis of IA.12 Although BAL is a safe procedure, the overall sensitivity of culture using BAL specimens is relatively low (estimated at 50%).13 Blood sampling is the optimal noninvasive diagnostic approach for IA.12 Despite this noninvasiveness, however, Aspergillus spp are rarely isolated from blood through conventional culture techniques-hence the reliance on tissue specimens to secure a definitive diagnosis of IA.12 Since results from cultures are relatively slow to obtain overall, IA is well established by the time the culture is positive. These challenges have resulted in ...
We regularly get people telling us about improvements made to their quality of life after avoiding certain foods - often those containing fungi (e.g. mushrooms, cheese, brewed drinks, bread, soy sauce, Miso and many more). Others find there is no difference whether they eat those foods or not - so what is actually known about allergy to foods for aspergillosis patients - or even those who are only allergic to the fungus Aspergillus rather than have an infection?. Firstly it is important to note that very little is known about the influence food has on the health of people predominantly living with allergies caused by breathing in allergens - almost nothing at all is known about those caused by Aspergillus itself so what follows are merely comments based on three or four research papers.. ...

A previous study explored factors discriminating colonization and true infection among non-transplant, non-neutropenic patients with repeated Aspergillus spp. isolation from lower respiratory samples. The present study explored the evolution of patients with Aspergillus colonization in that study to determine the percentage of cases progressing to aspergillosis and time to development. Clinical records were retrospectively reviewed (for each patient from his end date in the past study) and data from all respiratory processes suffered by patients up to April 2015 were recorded. Comparisons of variables were performed between colonized patients that developed aspergillosis and those that did not. A Kaplan-Meier curve was used to describe time to development of aspergillosis in chronic obstructive pulmonary disease (COPD) patients for II-IV stages of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification. Sixty seven colonized patients were followed, 12 of them (17.9%) developed
A.fumigatus-specific IgG is pivotal in making the diagnosis of chronic pulmonary aspergillosis (CPA). However, the cut-off value for A.fumigatus-specific IgG remains unknown. We included consecutive treatment-naïve subjects with chronic cavitary pulmonary aspergillosis (CCPA, cases). The controls were subjects with treated pulmonary tuberculosis, who had residual radiological abnormality and minimal symptoms. The diagnosis of CCPA was based on consistent clinicoradiological features along with demonstration of Aspergillus infection (growth of Aspergillus in sputum or bronchoalveolar lavage fluid [BALF] culture; serum or BALF galactomannan index,0.5 and ,1, respectively). For determining the cut-off of A.fumigatus-specific IgG (Phadia), subjects were randomly classified as derivation (two-thirds) and validation (one-third) cohort. One hundred and thirty-seven cases and 50 controls were included. The best cut-off value for A.fumigatus-specific IgG (derivation cohort) was 27.3 mgA/L (AUROC, 0.976) ...
Aspergillosis is an infection caused by the fungus Aspergillus. Aspergillosis describes a large number of diseases involving both infection and growth of fungus as well as allergic responses. Aspergillosis can occur in a variety of organs, both in humans and animals. The most common sites of infection are the respiratory apparatus (lungs, sinuses) and these infections can be: Invasive (e.g. - IPA) Non-invasive (e.g. Allergic Pulmonary Aspergillosis - ABPA) Chronic pulmonary and aspergilloma (e.g. chronic cavitary, semi-invasive) Severe asthma with fungal sensitisation (SAFS) Chronic pulmonary aspergillosis (CPA) is a long-term aspergillus infection of the lung and Aspergillus fumigatus is almost always the species responsible for this illness. Patients fall into several groups as listed below. Those with an aspergilloma which is a ball of fungus found in a single lung cavity - which may improve or disappear, or change very little over a few years.

There are a number of different manifestations of pulmonary aspergillosis. This study aims to review the radiology, presentation, and histological features of lung nodules caused by Aspergillus spp. Patients were identified from a cohort attending our specialist Chronic Pulmonary Aspergillosis clinic. Patients with cavitating lung lesions, with or without fibrosis and those with aspergillomas or a diagnosis of invasive aspergillosis were excluded. Demographic, laboratory, and clinical data and radiologic findings were recorded. Thirty-three patients with pulmonary nodules and diagnostic features of aspergillosis (histology and/or laboratory findings) were identified. Eighteen (54.5 %) were male, mean age 58 years (range 27-80 years). 19 (57.6 %) were former or current smokers. The median Charleston co-morbidity index was 3 (range 0-7). All complained of a least one of; dyspnoea, cough, haemoptysis, or weight loss. None reported fever. Ten patients (31 %) did not have an elevated Aspergillus IgG, and
Primary cutaneous aspergillosis (PCA) is an uncommon infection of the skin. There is a paucity of organized literature regarding this entity in regard to patient characteristics, associated Aspergillus species, and treatment modalities on outcome (disease recurrence, disease dissemination, and mortality). We reviewed all published reports of PCA from 1967 to 2015. Cases were deemed eligible if they included the following: patient baseline characteristics (age, sex, underlying condition), evidence of proven or probable PCA, primary treatment strategy, and outcome. We identified 130 eligible cases reported from 1967 to 2015. The patients were predominantly male (63.8%) with a mean age of 30.4 ± 22.1 years. Rates of PCA recurrence, dissemination, and mortality were 10.8%, 18.5%, and 31.5%, respectively. In half of the cases, there was an association with a foreign body. Seven different Aspergillus species were reported to cause PCA. Systemic antifungal therapy without surgery was the most common ...
To the Editor:. Aspergillosis comprises a range of diseases caused by the fungus Aspergillus.1,2 In 20% of cases, it appears as disseminated invasive aspergillosis.3 In the case of transplantation, it is associated with high rates of morbidity, mortality and extended hospitalisation.1 Its incidence varies according to the organ and in kidney transplantation, mortality reaches 70%.3,4Aspergillus is the fungus that most commonly affects the thyroid gland and it is generally confirmed in the autopsy.5-7 Reports of invasive aspergillosis that has disseminated to the thyroid gland, diagnosed ante mortem and treated in renal transplant patients, as in our case, are extremely rare.. CASE REPORT. A 49-year-old female received a deceased donor renal transplant. Induction therapy: anti-human thymocyte immunoglobulin, 5 doses of 1.5mg/kg/day.

The pharmacokinetics, efficacy, and safety of intravenous (iv) itraconazole (2 days at 400 mg/day, 12 days at 200 mg/day), followed by 12 weeks of oral capsules (400 mg/day) were studied in 31 immunocompromised patients with pulmonary invasive aspergillosis. All patients received iv itraconazole (median duration, 14 days), and 26 then received oral itraconazole (median duration, 78.5 days). After receiving iv itraconazole, concentrations increased rapidly, with trough plasma levels ⩾250 ng/mL in 91% of patients and in all patients by day 7. Concentrations ⩾500 ng/mL were observed in 64% of patients by day 2. Mean trough concentrations after 2 and 14 days were 670 and 850 ng/mL, respectively. Therapeutic levels were maintained after switching to oral capsules. A complete or partial response was seen at the last on-treatment assessment in 15 (48%) of 31 patients, with 6 (19%) showing stable disease. Itraconazole was well tolerated, with no unexpected effects. Overall iv/oral itraconazole was ...
Fungal infections in general require extended treatment and many of the drugs traditionally used to treat aspergillosis have toxic side effects. Advances in techniques have enabled better success with the treatment of nasal aspergillosis, but systemic aspergillosis in cats is still challenging to treat.. Treatment of nasal aspergillosis. After anesthetizing the cat, an endotracheal tube (breathing tube) is placed in the trachea (the windpipe), allowing the patient to breathe a mixture of anesthetic gases and oxygen. The area at the back of the throat is packed off with gauze sponges and an inflatable balloon catheter known as a Foley catheter. A topical antifungal agent (formulations of 1% clotrimazole or 1% bifonazole), is infused into the nose and frontal sinuses and the nostrils are sealed. The solution incubates for an hour, during which time the patient is periodically turned to ensure the solution contacts all of the surfaces of the sinuses. At the end of the incubation period, the ...
The ubiquitous airborne fungal pathogen Aspergillus fumigatus is inhaled by humans every day. In the lung, it is able to quickly adapt to the humid environment and, if not removed within a time frame of 4-8 hours, the pathogen may cause damage by germination and invasive growth. Applying a to-scale agent-based model of human alveoli to simulate early A. fumigatus infection under physiological conditions, we recently demonstrated that alveolar macrophages require chemotactic cues to accomplish the task of pathogen detection within the aforementioned time frame. The objective of this study is to specify our general prediction on the as yet unidentified chemokine by a quantitative analysis of its expected properties, such as the diffusion coefficient and the rates of secretion and degradation. To this end, the rule-based implementation of chemokine diffusion in the initial agent-based model is revised by numerically solving the spatio-temporal reaction-diffusion equation in the complex structure of ...
Aspergillus fumigatus infection due to primary infection of the ethmoid sinus affected the brain and orbit of an otherwise healthy elderly woman. Primary nasal sinus infection may be a chronic process analogous to aspergilloma of the lung: it may, however, assume a locally invasive course and spread to the orbit or brain, as in the case described. This form of Aspergillus infection is rare in Europe but common in hot dry areas like the Sudan. The infection was probably contracted by our patient while on holiday in South Africa. Histological recognition of the condition is important in these unusual sites--many cases are clinically diagnosed as a tumour and undergo biopsy.. ...
Chest radiographs (CXR) are an important diagnostic tool for the detection of invasive pulmonary aspergillosis (IPA) in critically ill patients, but their diagnostic value is limited by a poor sensitivity. By using advanced image processing, the aim of this study was to increase the value of chest radiographs in the diagnostic work up of neutropenic patients who are suspected of IPA.The frontal CXRs of 105 suspected cases of IPA were collected from four institutions. Radiographs could contain single or multiple sites of infection. CT was used as reference standard. Five radiologists and two residents participated in an observer study for the detection of IPA on CXRs with and without bone suppressed images (ClearRead BSI 3.2; Riverain Technologies). The evaluation was performed separately for the right and left lung, resulting in 78 diseased cases (or lungs) and 132 normal cases (or lungs). For each image, observers scored the likelihood of focal infectious lesions being present on a continuous ...
Invasive pulmonary aspergillosis diagnosed by antigen detection in urine. CHEST Journal Elsevier 0012-3692 10.1378/CHEST.105.4.1304B
Aspergillus fumigatus is the main cause of invasive aspergillosis in immunocompromised patients, and only a limited number of drugs for treatment are available. A screening method for new antifungal compounds is urgently required, preferably an appro
Two blinded, controlled trials were done to evaluate the usefulness of fungal antigen detection for the diagnosis of invasive aspergillosis. Detection of Aspergillus fumigatus carbohydrate by radioimmunoassay was compared with antibody detection by an enzyme-linked immunosorbent assay and with diagnostic microbiologic and histopathologic procedures. In the first trial, antigenemia was detected in 4 of 6 leukemic patients with invasive pulmonary aspergillosis, but not in 8 acute leukemic controls or in 24 normal controls. Fungal antigenemia persisted for 8 to 75 days in 4 patients and seroconversion occurred at the onset of pulmonary infiltrates in 3. Antibody to A. fumigatus was detected in 2 of the 6 patients with aspergillosis, but also in 2 leukemic controls and 6 normal controls. Aspergillus species were identified in four of seven bronchoscopies done in 5 patients with invasive pulmonary aspergillosis. Prospective nasal cultures grew Aspergillus species in 4 of the 6 patients with invasive ...
INTRODUCTION: The brain is almost always a localization of invasive aspergillosis, after hematogenous spread from pulmonary aspergillosis. Brain aspergilosis is not rare and is one of the worst prognosis factors of invasive aspergillosis. STATE OF ART: The incidence of this severe mycosis is currently on the rise due to the development of major immunosuppressive treatments. Brain aspergillosis is noteworthy for its vascular tropism, leading to infectious cerebral vasculitis, mainly involving thalamoperforating and lenticulostriate arteries, with a high frequency of thalamic or basal nuclei lesions. Extra-neurologic features that suggest this diagnosis are: i) risk factors for invasive aspergillosis (major or prolonged neutropenia, hematologic malignancies, prolonged corticosteroid treatment, bone marrow or solid organ transplant, AIDS); ii) persistent fever not responding to presumptive antibacterial treatment; iii) respiratory signs (brain aspergillosis is associated with pulmonary ...

Background: Invasive aspergillosis (IA) is an important cause of morbidity and mortality among lung transplant recipients. It is unclear which agent should be used for the prevention of IA in this population. We evaluated the impact of two prophylactic strategies to prevent IA among lung transplant recipients. Methods: We retrospectively reviewed medical records for all lung transplants performed between 2000 and 2007 at the University of California at San Francisco. Each patient was prescribed one of two fungal prophylactic regimens, a) inhaled prophylaxis only or b) any systemic prophylaxis (e.g. voriconazole) for 12 weeks plus inhaled amphotericin. We performed surveillance bronchoscopies at 2, 4, 6 and 8 weeks post transplantation. We performed brushings, washings and biopsies of suspicious lesions, examined patients and reviewed chest CT scans at the time of bronchoscopies. Using multivariable analyses, we explored the individual impact of either prophylactic strategy (inhaled only versus ...
A 51-year-old man, with a history of severe COPD and bilateral pneumothorax, who was under treatment for pulmonary tuberculosis due to mycobacterium avium, was admitted due to high-grade fever, weight loss, cough, and production of purulent sputum, for almost one month without any special improvement despite adequate antibiotics treatment in outpatient setting. A CT scan revealed multiple consolidations, fibrosis, scaring, and cavitary lesions in both upper lobes with newly shadows which were fungus balls inside them. Aspergillus flavius was isolated in three sputum samples, a diagnosis of chronic cavitary pulmonary aspergillosis was made, and treatment with intravenous amphotericin B was started. An initially clinical improvement was noted, and a first episode of minor hemoptysis was treated with conservative measures. Unfortunately a second major episode of hemoptysis occurred and he died almost immediately. Aspergilloma is defined as the presence of a fungus ball inside a preexisting pulmonary

RESULTS: 53 patients were included; median age was 61.5 years. Forty-seven had a lung condition, 25 suffered from COPD, 19 an active malignancy, 10 had previous pulmonary tuberculosis and 9 lung insterstitial disease. Twenty-eight patients presented with chronic cavitary pulmonary form (CCPA) and 20 with subacute invasive aspergillosis (SAIA). Species identified were A. fumigatus (34), A. niger (5), A. terreus (4) and A. flavus (3). All-cause 1 year mortality was 56%. Predictors of mortality were cancer history (OR, 9.5; 95% CI, 2.54-35.51; p,0.01) and SAIA (OR, 5.49; 95% CI, 1.49-19.82; p,0.01). Previous pulmonary tuberculosis, surgery for the treatment of CPA, and CCPA were found to be associated with lower mortality (OR, 0.05; 95% CI, ,0.01-0.47; p,0.01; OR, 0.16; 95% CI, 0.03-0.88; p=0.035 and OR 0.2, 95% CI, 0.01-0.67; p=0.01, respectively ...
Aspergillosis remains to be a life-threatening complication in immunocompromised patients. However, Aspergillus infection can be observed in non-immunocompromised individuals in rare cases. We report a case of liver aspergilloma in a chronic aplastic anemia patient under relatively intact immune status. Therapeutic strategy for this rare condition was extensively discussed and caspofungin acetate single agent first-line therapy was applied after careful consideration. Encouraging clinical and radiologic improvements were achieved in response to the antifungal salvage. Our long-term follow-up study also revealed a favorable prognosis. Based on this experience, we suggest caspofungin acetate as first-line therapy for treatment plans of liver aspergilloma.
A. fumigatus strains and culture conditions: A. fumigatus strains used in this study are listed in Table 1. A. fumigatus strains were propagated at 37° on complete medium or minimal medium (MM) with 0.5 mm of one of the following nitrogen sources: sodium glutamate, ammonium tartrate, sodium nitrate, sodium nitrite, or hypoxanthine (Cove 1966). Uridine and uracil were added at a concentration of 5 mm when appropriate. Selection of A. fumigatus mutants unable to utilize nitrate as the sole nitrogen source was obtained by plating spores on MM containing ammonium tartrate and 100 mm sodium chlorate (Cove 1966). The nature of the mutation was assessed by growth on MM supplemented with different nitrogen sources, as previously described (Cove 1976). Selection of A. fumigatus mutants auxotrophic for uridine and uracil was achieved on MM containing 1 mg/ml 5-fluoroorotic acid plus uridine and uracil (dEnfert 1996). Liquid cultures used for DNA-mediated transformation and genomic DNA preparation were ...
NEW ORLEANS-High doses of liposomal amphotericin B are no more effective than low doses in the treatment of invasive aspergillosis in neutropenic patients, European researchers reported at the Interscience Conference on Antimicrobial Agents and Chemotherapy. 1
Caspofungin has both in vitro and in vivo activities against a variety of fungi, including Aspergillus spp., although in vitro variations in activities by strain and species have been reported (2, 3, 9). Assessment of the in vitro activity of caspofungin against Aspergillus remains difficult because of the profound morphological changes that the drug effects on the hyphae (1, 3, 7), which are partially inhibited and which appear short, stubby, and highly branched (3). Despite the difficulties involved with the in vitro assessment of antifungal activity, caspofungin remains an attractive compound for use against Aspergillus spp. due to its favorable toxicity profile and ability to be administered intravenously. The antifungal activity of caspofungin is similar to that of amphotericin B against Aspergillus in immunosuppressed mice (2), although its fungicidal effects occur at a slower rate than those of amphotericin B (6), and furthermore, it has a target that is not found in mammals, which itself ...
Invasive pulmonary aspergillosis (IPA) optimal duration of antifungal treatment is not known. In a joint effort, four international scientific societies/groups performed a survey to capture current practices in European haematology centres regarding management of IPA. We conducted a cross-sectional internet-based questionnaire survey in 2017 to assess practices in sixteen European countries concerning IPA management in haematology patients including tools to evaluate treatment response, duration and discontinuation. The following four groups/societies were involved in the project: European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Fungal Infection Study Group (EFISG), Infectious Diseases Working Party-European Society for Blood and Bone Marrow Transplantation (IDWP-EBMT), European Organisation for Research and Treatment-Infectious Disease group (EORTC-IDG) and Sorveglianza Epidemiologica Infezioni nelle Emopatie (SEIFEM). A total of 112 physicians from 14/16 countries ...
Aspergilloma and invasive aspergillosis are important opportunistic infections caused by Aspergillus species, among which Aspergillus fumigatus is the most common species associated with human disease. We developed an enzyme-linked immunosorbent assay (ELISA)-based antibody assay with Afmp1p, a purified recombinant antigenic cell wall galactomannoprotein of A. fumigatus. Evaluation of the test with guinea pig sera against A. fumigatus and other pathogenic fungi indicated that this assay was specific for A. fumigatus. Clinical evaluation revealed that the assay was 100% sensitive for patients with aspergilloma and 33.3% sensitive for patients with invasive aspergillosis. No false-positive results were found for serum samples from 80 healthy blood donors, 6 patients with typhoid fever, 4 patients with melioidosis, 20 patients with penicilliosis marneffei, 5 patients with candidiasis, and 4 patients with cryptococcosis, indicating a high specificity of the test. Thus, this ELISA-based test for the ...
Invasive aspergillosis (IA), often caused by Aspergillus fumigatus, is an important cause of death of immunocompromised patients. Several DNA-extraction methods and PCR assays are available for detecting Aspergillus fumigatus DNA in bronchoalveolar lavage (BAL) samples of patients with invasive aspergillosis. These methods are often time consuming and emphasize the need to develop a clinical relevant rapid DNA isolation assay that gives reliable results in a short time. We have developed a new and rapid method which yields results within six hours.This was achieved by combining high-speed cell disruption using a mechanical extraction procedure (FastPrep), with a real-time PCR assay based on TaqMan technology.A newly designed Aspergillus-fumigatus-specific probe and Aspergillus-fumigatus-specific primers were established. This combination also produces quantitative results by comparing the results with a DNA serial dilution used in the real-time PCR. BAL fluids and other material from 204 ...

If allergic bronchopulmonary aspergillosis (ABPA) is suspected, youll have a skin prick test. You may be referred to a specialist at an allergy clinic for the test.. Your skin will be pricked with a needle that contains a small amount of aspergillus mould. If youre allergic, the area of skin where the needle was inserted will come up in a hard red bump.. Blood tests are also used to check for immunoglobulin E (IgE) antibodies, which will be produced by your immune system if youre allergic to the aspergillus mould. Antibodies are special proteins that help fight infections and are markers of allergy.. You may also have a computerised tomography (CT) scan to check whether theres a build-up of mucus in your lungs or bronchiectasis, which is common in ABPA.. As well as having severe asthma, someone with severe asthma with fungal sensitisation (SAFS) will also be sensitised (allergic) to one or more types of fungi. As with ABPA, this can be diagnosed using a skin prick test, where your skin is ...

Aspergillus fumigatus is a ubiquitous opportunistic fungal pathogen that can cause severe infections in immunocompromised patients. Conidia that reach the lower respiratory tract are confronted with alveolar macrophages, which are the resident phagocytic cells, constituting the first line of defense. If not efficiently removed in time, A. fumigatus conidia can germinate causing severe infections associated with high mortality rates. Mice are the most extensively used model organism in research on A. fumigatus infections. However, in addition to structural differences in the lung physiology of mice and the human host, applied infection doses in animal experiments are typically orders of magnitude larger compared to the daily inhalation doses of humans. The influence of these factors, which must be taken into account in a quantitative comparison and knowledge transfer from mice to humans, is difficult to measure since in vivo live cell imaging of the infection dynamics under physiological ...

The aim of this multicenter prospective study was to evaluate the incidence of invasive fungal infections (IFIs) in adult and pediatric patients with hematologic malignancies, involving nine nosocomial facilities in Southern Italy over a period of 18 months. Furthermore, results of an environmental microbial surveillance routinely carried out in some of the enrolled hospitals are reported. A total of 589 onco-hematological patients were enrolled and 27 IFIs were documented. The main infections were caused by yeasts, more than filamentous fungi (overall incidence of 2.7% and 1.9%, respectively). The yeasts were mainly represented by Candida spp. (87.5%), all isolated by blood cultures; C. parapsilosis was the most common species. Among mould infections, the most frequent site was the lung, with regard to aspergillosis (81.8%). In six of the 10 patients with suspected aspergillosis, the diagnosis was made by the detection of galactomannan and (1,3)-β-d-glucan antigens. The microbiological surveillance
