Abstract
BACKGROUND Mycetomas are uncommon in lung transplant recipients. Prior studies have shown increased mortality associated with mycetoma in lung transplant recipients (LTR). We reviewed our center's experience in outcome of LTRs with pre -or post-transplant mycetoma. METHODS We retrospectively reviewed electronic health records of LTRs performed at our institute between January 1, 2013 to December 31, 2020. RESULTS Mycetoma was present in less than 1 percent of LTR patients (7/1086). Mean age at the time of the transplant was 65 years. Idiopathic pulmonary fibrosis (5/7), interstitial lung disease (1/7), and sarcoidosis (1/7) were underlying pulmonary diagnoses. Seventy-one percent (5/7) received single lung transplant and 29% received double lung transplant. Seventy-one percent had negative serum galactomannan vs 29% (2/7) of patients who had positive serum galactomannan (one post and one pre). Fifty-seven percent had positive bronchoalveolar aspergillus galactomannan (23% had negative). A total of 42% (3/7) were found to have mycetoma before transplant and 58% (4/7) had mycetoma post transplant. Chest computed tomography findings in all patients were consistent with mycetoma. CONCLUSIONS In our cohort of patients, mycetoma was not found to be the primary cause of death if diagnosed pre transplant. Transplant recipients with mycetoma pre transplant did not develop invasive fungal infection or mycetoma post transplant. Careful evaluation of lung transplant candidates with mycetoma is critical. Further studies are needed to determine optimal duration of antifungal therapy and to determine if surgical resection may be needed to manage post-lung transplant mycetoma.

Wang B, Liu G, Luo M, Zhang X, Wang Q, Zou S, Zhang F, Jin X, Zhang L. Preparation and Evaluation of a Horse Antiserum against the Venom of Sea Snake Hydrophis curtus from Hainan, China. Toxins (Basel) 2022; 14:toxins14040253. [PMID: 35448862 PMCID: PMC9024827 DOI: 10.3390/toxins14040253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 03/22/2022] [Accepted: 03/30/2022] [Indexed: 01/27/2023] Open
Abstract
Sea snake venom is extremely toxic, and it can induce severe respiratory failure and cause high mortality. The most effective first aid treatment for sea snake bites is to inject antivenom as soon as possible. However, in China, there are only four types of terrestrial snake antivenoms, none of which are effective in the treatment of sea snake bites. In order to develop an antivenom for the dominant species of sea snakes in Chinese seas, Hydrophis curtus venom (HcuV) was chosen as the antigen to immunize horses. From immune plasma, a high-titer Hydrophis curtus antivenom (HcuAV) was prepared. In vitro assessment showed that HcuAV had a cross-neutralizing capacity against HcuV and Hydrophis cyanocinctus venom (HcyV). In vivo assessment indicated that HcuAV injection could significantly improve the survival rates of the HcuV and HcyV envenomated mice (0% to 100% and 87.5%, respectively) when it was injected at a sufficient amount within the shortest possible time. In addition, HcuAV could also effectively alleviate multiple organ injuries caused by HcuV. These results provide experimental support for the future clinical application of HcuAV.

Abstract
Background Chronic pulmonary aspergillosis (CPA) develops in various underlying pulmonary conditions. There is scarce data evaluating interstitial lung disease (ILD)/abnormalities (ILA) as such conditions, and it has not been explored much whether non-tuberculous mycobacterial pulmonary disease (NTM-PD) is a prognostic factor for mortality in CPA patients. Few reports had investigated prognostic factors of CPA including underlying pulmonary conditions. Objectives To explore prognostic factors of CPA including pulmonary conditions. Methods We conducted a retrospective cohort study of 264 CPA patients from a center for pulmonary aspergillosis in Japan. Results Survival rates were 78.7%, 61.0%, and 47.4% at 1, 3, and 5 years, respectively. Of 264 patients, 53 (20.1%) and 87 (33.1%) were complicated with ILA and NTM-PD. Several independent prognostic factors were identified by multivariate Cox proportional analysis: ILA (HR 1.76, 95%CI 1.06–2.92, p = 0.029), age (1.05, 1.02–1.08, p<0.001), male sex (2.48, 1.34–4.59, p = 0.004), body mass index of <18.5 kg/m2 (1,87, 1.20–2.90, p = 0.005), presence of aspergilloma (1.59, 1.04–2.45, p = 0.033), and lower serum albumin (0.56, 0.38–0.83, p = 0.004). NTM-PD was not associated with higher mortality (0.85, 0.52–1.38, p = 0.51). Conclusions The poor prognosis of CPA and several prognostic factors were revealed. Early diagnosis and intervention is required with reference to such factors.

Abstract
BACKGROUND Pulmonary mycoses resemble clinically and radiologically chronic pulmonary tuberculosis. Studies describing the prevalence, etiology and clinical features of pulmonary mycosis are of crucial importance in the Brazilian Amazon. AIMS To estimate the frequency of pulmonary mycoses in smear-negative tuberculosis patients; to describe their demographic, epidemiological, and clinical characteristics; and to evaluate diagnostic methods. METHODS A cross-sectional study was conducted at two tuberculosis reference institutions in Amazonas, Brazil. We included 213 patients and collected clinical data, blood and induced sputum to perform serological, direct microscopy, microbiologic culture and PCR-based assays to identify infections caused by Aspergillus fumigatus, Paracoccidioides brasiliensis, Histoplasma capsulatum, Cryptococcus, and HIV. Chest computed tomography was also performed. RESULTS Pulmonary mycoses were diagnosed in 7% (15/213) of the cases, comprising ten aspergillosis cases, three cases of paracoccidioidomycosis and one case each of histoplasmosis and cryptococcosis. Among the patients with pulmonary mycoses, 86.7% were former tuberculosis patients. The most significant clinical characteristics associated with pulmonary mycoses were cavity-shaped lung injuries, prolonged chronic cough and hemoptysis. CONCLUSIONS Our study confirmed the high prevalence of pulmonary mycoses in smear-negative tuberculosis patients in the Brazilian Amazon.

Abstract
OBJECTIVE To present an interesting case of left opaque hemithorax in an adult female and discuss its assessment and management. METHODS Design: Case Report. SETTING Tertiary care hospital. PATIENT One. RESULTS 44yrs retropositive female admitted with complaints of acute onset dry cough since 15-20 days, sudden breathlesness since 5 days which was progressive in nature, left sided heaviness in chest since 5 days. CECT Thorax showed complete collapse of left lung with cut off of left main bronchus while video bronchoscopy showed left main bronchus completely blocked with very thick necrotic mass and was difficult to dislodge. Debulking with cryo probe was done and left main bronchus was completely cleared off. Allergen panel showed very high serum IgE, high S.IgE against aspergillus and high specific S.IgG against aspergillus. Patient and her Chest X-ray showed significant improvement post cryo debulking and was discharged satisfactorily on oral voriconazole therapy. CONCLUSION Endobronchial aspergillosis is characterized by massive intrabronchial overgrowth of the aspergillus species, mainly aspergillus fumigatus. Most patients with chronic pulmonary aspergillosis, including those with simple aspergillomas and Aspergillus nodules, have positive Aspergillus IgG antibodies in the blood. We hereby present a case of 44 yrs female presenting with complaints of dry cough and dyspnea and was diagnosed with endobronchial aspergillosis with complete obliteration of left main bronchus by fungal debris in which cryo debulking was done which relieved the symptoms significantly and was discharged in satisfactory condition on oral voriconazole therapy.

Abstract
Chronic pulmonary aspergillosis (CPA) is a slow and progressive disease that develops in preexisting lung cavities of patients with tuberculosis sequelae, and it is associated with a high mortality rate. Serological tests such as double agar gel immunodiffusion test (DID) or counterimmunoelectrophoresis (CIE) test have been routinely used for CPA diagnosis in the absence of positive cultures. However, these tests have been replaced with enzyme-linked immunoassay (ELISA) and, a variety of methods. This systematic review compares ELISA accuracy to reference test (DID and/or CIE) accuracy in CPA diagnosis. It was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The study was registered in PROSPERO under the registration number CRD42016046057. We searched the electronic databases MEDLINE (PubMed), EMBASE (Elsevier), LILACS (VHL), Cochrane library, and ISI Web of Science. Gray literature was researched using Google Scholar and conference abstracts. We included articles with patients or serum samples from patients with CPA who underwent two serological tests: ELISA (index test) and IDD and/or CIE (reference test). We used the test accuracy as a result. Original articles were considered without a restriction of date or language. The pooled sensitivity, specificity, and summary receiver operating characteristic curves were estimated. We included 14 studies in the review, but only four were included in the meta-analysis. The pooled sensitivities and specificities were 0.93 and 0.97 for the ELISA test. These values were 0.64 and 0.99 for the reference test (DID and/or CIE). Analyses of summary receiver operating characteristic curves yielded 0.99 for ELISA and 0.99 for the reference test (DID and/or CIE). Our meta-analysis suggests that the diagnostic accuracy of ELISA is greater than the reference tests (DID and/or CIE) for early CPA detection.

Abstract
Background In patients who are not amenable to surgical resection (cavernostomy), it is difficult to achieve palliation of hemoptysis from pulmonary aspergilloma. There are only 9 cases with a short follow-up that have reported the use of radiotherapy for hemoptysis in this scenario. Methods A retrospective series of 21 patients with chronic necrotizing pulmonary aspergillosis were treated with radiotherapy (20 Gray) from 1990 to 2002. The outcome measures were the period from tuberculosis treatment to the onset of hemoptysis, hemoptysis resolution rate, change in Zubrod performance status after 30 days of the completion of radiotherapy, local failure-free survival, and overall survival. Results The median time between tuberculosis treatment and the onset of hemoptysis due to aspergilloma was 9 years. After radiotherapy, general status improved and the hemoptysis resolved in all patients. During the follow-up period, 4 failures occurred, with a 5-year local failure-free survival rate of 82 % and a 5-year overall survival rate of 59 %. Of these failures, 2 patients died due to recurrence of the hemoptysis, and 2 were rescued (using cavernostomy and reirradiation). The presence of chronic obstructive pulmonary disease (COPD) (p = 0.021) and female gender (p = 0.032) were negatively associated with overall survival. None of the variables was related to local control. Conclusions Based on these long-term data, radiotherapy is a potential option for controlling bleeding due to fungus balls. Female patients and COPD were associated with lower survival.

Abstract
The diagnosis of chronic pulmonary aspergillosis (CPA) depends on the radiologic image and the identification of specific antibodies. The present study aimed to evaluate accuracy parameters of enzyme-linked immunosorbent assay (ELISA) and of the determination of serum galactomannan level in the diagnosis of patients with CPA, comparing these results with the double agar gel immunodiffusion (DID) test. In addition, the prevalence of cross-reactivity and the serological progression after treatment were evaluated by comparing DID and ELISA. Six study groups were formed: G1: 22 patients with CPA, 17 of whom had Aspergillus fungus ball, one chronic cavitary pulmonary aspergillosis (CCPA) and four chronic fibrosing pulmonary aspergillosis (CFPA); G2: 28 patients with pulmonary tuberculosis (TB); G3: 23 patients with histoplasmosis (HST); G4: 50 patients with paracoccidioidomycosis (PCM); G5: 20 patients with cryptococcosis (CRC); and G6: 200 healthy controls. Serum antibodies were measured by DID and ELISA, with two antigen preparations—Aspergillus fumigatus (DID1, ELISA1) and a pool of A. fumigatus, A. flavus and A. niger antigens (DID2, ELISA2). The Platélia Aspergillus Enzyme Immunoassay (EIA) kit was used to measure galactomannan. The cut-off points of ELISA were determined for each antigen preparation and for the 95% and 99% confidence intervals. Despite the low sensitivity, DID was the technique of choice due to its specificity, positive and negative predictive values and positive likelihood ratio–especially with the antigen pool and due to the low frequency of cross-reactivity. ELISA1 and a 0.090 cut-off showed high sensitivity, specificity and negative predictive value, but a high frequency of cross-reactivity with CRC. The best degree of agreement was observed between ELISA1 and ELISA2. The detection of serum galactomannan showed high sensitivity, comparable to ELISA2. The immunodiffusion test showed an excellent relationship with the progression after treatment, which made it the reaction of choice for patient follow-up.

Abstract
OBJECTIVE To estimate the global burden of chronic pulmonary aspergillosis (CPA) after pulmonary tuberculosis (PTB), specifically in cases with pulmonary cavitation. METHODS PTB rates were obtained from the World Health Organization and a scoping review of the literature was conducted to identify studies on residual pulmonary cavitation after PTB and estimate the global incidence of CPA after PTB. Having established that from 21% (United States of America) to 35% (Taiwan, China) of PTB patients developed pulmonary cavities and that about 22% of these patients developed CPA, the authors applied annual attrition rates of 10%, 15% and 25% to estimate the period prevalence range for CPA over five years. Analysis was based on a deterministic model. FINDINGS In 2007, 7.7 million cases of PTB occurred globally, and of them, an estimated 372,000 developed CPA: from 11,400 in Europe to 145,372 in South-East Asia. The global five-year period prevalence was 1,174,000, 852,000 and 1,372,000 cases at 15%, 25% and 10% annual attrition rates, respectively. The prevalence rate ranged from < 1 case per 100,000 population in large western European countries and the United States of America to 42.9 per 100,000 in both the Democratic Republic of the Congo and Nigeria. China and India had intermediate five-year period prevalence rates of 16.2 and 23.1 per 100,000, respectively. CONCLUSION The global burden of CPA as a sequel to PTB is substantial and warrants further investigation. CPA could account for some cases of smear-negative PTB. Since CPA responds to long-term antifungal therapy, improved case detection should be urgently undertaken.

Abstract
An 88-kDa component secreted in vitro by Aspergillus fumigatus has been purified by sequential chromatographic procedures. The molecule is a glycoprotein with an N-linked sugar moiety composed of mannose glucose, and galactose (16:10:1). It is recognized by antibodies from patients with aspergilloma and has potential for the immunodiagnosis of aspergilloma. The antigenicity is associated with the polypeptide part of the molecule (79 kDa).

Abstract
Aspergillus species are ubiquitous fungi and have been implicated as the causative agents of a variety of lung disorders in humans. These disorders include allergic, saprophytic, and systemic manifestations. The allergic disorders mainly affect atopic persons, and invasive or systemic diseases affect immunosuppressed individuals. Immunodiagnosis can help the practitioner diagnose these diseases. Demonstration of circulating antibodies is a useful criterion, but the lack of dependable and standardized antigens is a limiting factor in the diagnosis of most Aspergillus-induced diseases. Despite this limitation, however, immunodiffusion and enzyme-linked immunosorbent assays have been widely used for the detection of antibodies in the sera of patients with aspergillosis. Similarly, crude and semipurified antigens are being used to demonstrate skin hypersensitivity in patients, and several methods have been useful in the detection of antigenemia in patients with invasive aspergillosis. With a growing number of reports on the incidence of aspergillosis and an increase in the number of immunosuppressed individuals in the population, more rapid methods and more reliable reagents for immunodiagnosis are needed. With recent attempts at obtaining reliable reagents for through hybridoma technology and molecular biological techniques, substantial progress toward efficient immunodiagnosis may be achieved.

Abstract
Sera from 38 patients with invasive aspergillosis were tested by Western immunoblotting for the presence of antibodies to antigens of Aspergillus fumigatus present in a mycelial extract of the organism. All of the sera contained antibodies to an antigen of molecular weight 58,000, which was which was determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. It was the only antigen recognized in approximately 90% of the sera tested. The 58-kDa antigen is an abundant component of mycelial extracts composing approximately 50% of the Coomassie blue-stained protein. The antigen also contains carbohydrate, since it is stained by the carbohydrate stain periodic acid-Schiff and it binds to the lectin concanavalin A. It was purified by immunoaffinity chromatography employing a monoclonal antibody directed against an epitope on the 58-kDa antigen. Analysis of the purified antigen by gas-liquid chromatography revealed the presence of mannose, galactose, and glucose residues in a 2:1:2 ratio. The ratio of protein to carbohydrate is 1.16:1. The protein is slightly acidic, containing relatively high quantities of glutamic and aspartic acids, glycine, alanine, serine, and threonine. The 58-kDa antigen also contains phosphate groups as part of its structure. Serological activity was totally destroyed after treatment with sodium metaperiodate and was partially destroyed after treatment with pronase. The 58-kDa antigen was not able to hydrolyze protein.

Abstract
Four commercially available Aspergillus fumigatus antigens were compared in an IgG enzyme linked immunosorbent assay by testing multiple sera from 19 patients who had received renal and hepatic allografts and who had histologically confirmed invasive aspergillosis. Raised antibody levels were found in 16 of the 19 patients. More antibody responses were detected by culture filtrate antigens, but somatic antigens often detected antibodies sooner. When antibodies to Aspergillus antigens were present before transplantation the onset of fatal disseminated infection was earlier. Antibody levels often fell to within the normal range, even in cases of fulminant disseminated infection. Repeated serology was essential for detection of an antibody response.

Abstract
A rapid enzyme-linked immunosorbent assay (ELISA) where component incubation periods were shortened to one hour, was compared with agar gel double diffusion (AGDD) and a standard ELISA procedure for detecting antibodies to Aspergillus fumigatus in 28 asthmatic patients with suspected allergic aspergillosis. Using two A fumigatus antigens the rapid ELISA compared well with AGDD and the standard ELISA method. Eleven sera that reacted with both antigens in AGDD were all positive against antigen 1 in both forms of ELISA, but two failed to react with antigen 2 in the standard ELISA and three failed to react with this antigen in the rapid method. Thirteen AGDD-negative sera were also negative in both forms of ELISA. The rapid ELISA provides a sensitive and reproducible test for routine serological investigation of allergic aspergillosis.

Abstract
Methods for the preparation of antigens from clinically isolated cultures of Aspergillus were standardized. Sera from 25 suspected cases of pulmonary aspergillosis were tested against antigens prepared by us, from 4 strains of A. fumigatus and one strain of A. flavus, using the Ouchterlony double diffusion and immunoelectrophoretic techniques. Of the 25 sera, 18 reacted positively with antigens of A. fumigatus, one with A. flavus and 2 with both these species. Antigens of two non-pathogenic Aspergilli included in the study failed to react with any of the sera. Our antigen preparations gave more numerous as well as sharper precipitin lines than the commercial Bencard antigens which were used for comparison. Moreover, mycelial antigens from 48 to 96 h old cultures revealed precipitin lines comparable to that of the routine, 4 week old culture filtrate antigens, thus suggesting that the incubation period for obtaining antigens could be cut down considerably.

Abstract
A child developed eyelid swelling that was diagnosed in succession as an abscess, eosinophilic granuloma, malignancy, and inflammatory pseudotumor. Treatment modalities included antibiotics, radiation and corticosteroids. Repeated histologic examination finally provided the diagnosis of orbital mycosis, most consistent with aspergillosis. Despite six weeks of therapy with Amphotericin B, an exenteration was required. Amphotericin B was continued for another six weeks, and there has been no evidence of recurrent disease after two years of follow-up. The problems encountered in the diagnosis and management of this unusual infectious disease of the orbit in children are discussed in detail.

Abstract
To determine the significance of Aspergillus species isolated from sputum or other respiratory secretions with respect to the diagnosis of invasive pulmonary aspergillosis, the clinical records and radiographs of all patients whose respiratory secretion cultures yielded an Aspergillus species between 1972 and 1978 were reviewed. All known predispositions to invasive aspergillosis, e.g., presence of cancer or granulocytopenia, and therapy with corticosteroids, antibiotics, and cytotoxic drugs, were significantly associated with proven or probable invasive pulmonary aspergillosis. Most notable were patients with acute leukemia and granulocytopenia. Prolonged duration of hospitalization between initial isolation (greater than 2 weeks) and multiple isolates (greater than three isolates) were also significantly associated with a high frequency of proven or probable disease. Isolation of A. niger was only rarely associated with proven or probable disease (one of eight patients). The isolation of A. fumigatus and A. flavus from respiratory secretions does not usually represent laboratory contamination and must be interpreted in the light of known predispositions to aspergillosis. In some situations, e.g., granulocytopenic patients with acute leukemia, even a single isolation carries a high likelihood of invasive aspergillosis.

Abstract
Spores of Aspergillus fumigatus have been found to be abundantly present in the outdoor air at a site where large scale experimental composting of sewage sludge is in progress at Beltsville, Maryland. The health significance of this finding, for that site and for others in the future, is still only incompletely understood. Further studies are in progress to characterize absolute concentrations of the spores of the fungus in air at the site, spore dispersal by air from composting operations, and background environmental spore levels in air. The present paper contains a list of references to papers on health effects of A. fumigatus, many published in the past ten years, along with a review of the same designed to assist the reader in finding information on particular aspects of the subject in the literature. It is intended primarily as an aid to individuals interested in sludge composting and wishing to attain an insight into the A. fumigatus-composting situation, but it may also interest others concerned with other substrates which become moldy at 40--50 C. A. fumigatus has been found in great numbers in naturally and artificially heated environments such as decaying leaves, compost heaps, solar heated sloughs, cooling canals for nuclear power generators, silos, grain storage bins, boiler rooms, detritus around steam turbines and sauna baths. The evident practical merits of sludge composting have been described elsewhere; the information presented here has its main significance in respect to requirements for choice of locations for composting sites and to process and design criteria.

Abstract
The influence of immunosuppression on the course of experimental aspergillosis was investigated. Rabbits (2.2--2.5 kg) were divided into four groups. Group one received no drugs and was given 10(6) spores intravenously (IV) or intratracheally (IT) on two occasions one week apart. Weight gain or loss, appearance or disappearance of aspergillus antigen and/or antibody, and detection of aspergillosis at autopsy were followed. Group 2 received weekly injections of cyclophosphamide (70 mg/kg) starting two weeks prior and throughout the experiment. Animals in group three received either 1.14 or 2.25 mg/kg/day methyl prednisolone and group four received 2.28 mg/kg/day methyl prednisolone and 70 mg/kg/week cyclophosphamide. In group one, serum antigen levels were detected within a week of infection followed by antibody (I.D.) levels for three months. All animals grew normally and no infection was detected at autopsy. In group 2, animals survived one but not two challenges and had Ag but no Ab. In group 3, animals survived two challenges at the lower drug level but not the higher. All animals in group 4 succumbed to one challenge.

Abstract
Serum specimens from 138 patients suffering from chronic respiratory disorders including 63 with allergic bronchopulmonary aspergillosis (ABPA), 2o with suspected ABPA, 15 with pulmonary tuberculosis, 14 with bronchial asthma, 10 with chronic bronchitis and 6 with miscellaneous pulmonary conditions were studied for circulating antibodies to Aspergillus. The ammonium sulfate test was empolyed with an iodine-125 labeled mycelial component derived from Aspergillus fumigatus. When compared to normal controls from the same area, this test indicated that sera from 82 per cent of patients with ABPA had elevated binding titers to the radiolabeled antigenic component. Immunodiffusion using a culture filtrate antigen from A. fumigatus, revealed precipitating antibody to this fungus in 89 percent of sera from ABP patients. The majority of patients with ABPA demonstrated marked elevations of total serum IgE, moderate elevations of serum IgA and IgD and slightly increased levels of IgG and IgM.

Abstract
Diffuse fluorescence in an indirect fluorescent-antibody test for antibody to Aspergillus fumigatus was eliminated by using germlings, rather than hyphae, as antigen. The modified method yielded diagnostic titers larger than or equal to 1:32 in 24 of 25 known cases, was highly specific, and showed good correlation with clinical status and results of immunodiffusion. This technique, which uses the germling antigen, inactivation of test serum at 59 +/- 1 degrees C, and anti-immunoglobulin G conjugate, is a sensitive, specific, and reliable quantitative indicator of aspergillosis and is useful in following the course of the disease.

Abstract
Precipitin tests by two different methods, double-diffusion (DD) and counterimmunoelectrophoresis (CIE), and measurements of total and specific IgE against Aspergillus fumigatus were made in 50 patients with chronic allergic bronchopulmonary aspergillosis and in three control groups--atopics with a positive immediate prick test to A. fumigatus but no evidence of allergic aspergillosis, atopics with a negative prick test to A. fumigatus, and non-atopics. Precipitins were found in 84% and 78% of the patients with aspergillosis by the DD and CIE methods respectively. Precipitins were also found in 6 out of 27 (22%) patients with a positive prick test to A. fumigatus but no evidence of aspergillosis and in 1 of 24 patients with a negative prick test to A. fumigatus. The means of specific and total IgE values were significantly higher in the group of patients with aspergillosis than in the three other groups of patients. The increase in specific but not total IgE showed a statistically significant correlation with positive precipitin tests in the patients with aspergillosis. Total IgE but not specific IgE values were significantly higher (0-02 less than P less than 0-05) in patients who had had a transient radiographic shadow in the previous three months. Positive precipitin tests were also significantly correlated with the number of transient shadows in the past and with the interval of time since the last transient shadow.

Abstract
Detection of serum precipitins to Aspergillus fumigatus by counterimmunoelectrophoresis is compared with the immunodiffusion technique. Eight of nine (89%) sera from patients with proven A. fumigatus infection were positive by both methods. No serum from subjects with other systemic mycoses, bacterial infections, or healthy controls had detectable precipitins. The highest serum precipitin titers were found in sera of patients with the mycetomal and invasive forms of the disease. Detection of A. fumigatus serum precipitins by counterimmunoelectrophoresis compares favourably with immunodiffusion and has the advantage of significantly reducing the time required for results.
