A Case of Type I Food Allergy Induced by Monosodium Glutamate.

Monosodium glutamate (MSG), a salt form of a non-essential amino acid, is widely used as a food additive, particularly in Asian cuisines, due to its unique flavor-enhancing qualities. Type I allergic reactions to MSG have not previously been reported. Our patient, a 21-year-old woman, was 14 years old when she first noticed swelling of her tongue (but no oral itching, diarrhea, or abdominal pain) after eating various snack foods. Current skin prick testing elicited a weak positive reaction to MSG. We then performed an oral challenge test during which our patient ingested potato snacks. Subsequent histology showed telangiectasia of the buccal mucosa, interstitial edema in the subepithelial submucosa, and mast cell infiltration. Oral mucosal challenge tests using sodium glutamate confirmed oral swelling in this patient. This report is the first to confirm a case of type 1 allergy to MSG by combining pathology findings with the results of challenge testing.

Intravenous cyclophosphamide and immunoglobulin ameliorated visual field defects in a patient with eosinophilic granulomatosis with polyangiitis.

Treating ocular involvement in eosinophilic granulomatosis with polyangiitis (EGPA) can be challenging. We present the case of a 37-year-old woman with EGPA who had severe bilateral visual field defects. Laboratory results showed leukocytosis (17,500 WBC/µL, 25.8 % eosinophils), negative MPO-ANCA titer, and elevated PR3-ANCA level (33.2 IU/mL). Diffusion-weighted MRI revealed bilateral hyperintense occipital lesions, which were more prominent on the left. Her therapy initially included a steroid pulse, followed by daily prednisolone, but her visual field defects remained refractory. The addition of intravenous cyclophosphamide (5 courses) and intravenous immunoglobulin decreased her optic neuropathy and resolved her visual field defects.

Dupilumab suppresses relapsing chronic eosinophilic pneumonia with severe asthma.

Dupilumab-induced hypereosinophilia is mediated by blockade of the IL-4/IL-13 pathway, which reduces eosinophil migration from peripheral blood. The increase in peripheral blood eosinophils may lead to chronic eosinophilic pneumonia (CEP) and/or eosinophilic granulomatosis with polyangiitis, but a direct causal connection between dupilumab and eosinophilic lung diseases has not been established. A 33-year-old Japanese woman with bronchial asthma since age three was treated with fluticasone propionate plus salmeterol twice daily after several asthma exacerbations at age 17. Her course was complicated by CEP at age 33 which resolved without the need for systemic steroids. However, in the four months following resolution of her CEP, the patient had three asthma exacerbations, and a recurrence of CEP, with blood leukocytes of 8500/µL, of which 25.0% were eosinophils. She was treated with prednisolone 50 mg/day, but she could not continue this dose due to the onset of myalgia. Then she had relapsing CEP twice within three months. She was treated with prednisolone 15 mg/day for CEP, but she had persistent asthma for more than one month; dupilumab was added at 600 mg, followed by 300 mg every two weeks. In the first month of treatment with dupilumab, the patient's asthma symptoms resolved completely, and she had only one relapse of CEP. In 12 months of follow-up, she had neither an asthma exacerbation nor another relapse of CEP. Dupilumab may be a promising treatment for patients with refractory asthma complicated by recurring CEP and undesirable steroid side effects.

Eosinophilic granulomatosis with polyangiitis and severe cardiac involvement in a patient surviving for 34 years.

INTRODUCTION: Many studies have reported a poor prognosis for eosinophilic granulomatosis with polyangiitis (EGPA) patients with cardiac involvement. CASE STUDY: A woman developed EGPA at 37 years of age, with weight loss, numbness in the right upper and lower extremities, muscle weakness, skin rash, abdominal pain, chest pain, an increased peripheral blood eosinophil count (4165/µL), and necrotizing vasculitis on peroneal nerve biopsy. The patient was treated with prednisolone, immunosuppressants, intravenous immune globulin, and mepolizumab, but she experienced many relapses, with chest pain, abdominal pain, numbness, and paralysis, over a long period. The patient died from aspiration pneumonia at 71 years of age after undergoing left total hip arthroplasty for left hip neck fracture. RESULTS: Autopsy showed bronchopneumonia in the lower lung lobes on both sides, as well as infiltration of inflammatory cells, including neutrophils and lymphocytes. There was no evidence of active vasculitis in either the lung or colon. At autopsy the heart showed predominantly subendocardial fibrosis and fatty infiltration, but no active vasculitis or eosinophilic infiltration. CONCLUSION: To our knowledge, there have been no autopsy reports of EGPA patients who have survived for 34 years with recurrent cardiac lesions. In this case, the cardiac involvement (active vasculitis and eosinophilic infiltration) had improved by the time of death.

Long-term mepolizumab treatment reduces relapse rates in super-responders with eosinophilic granulomatosis with polyangiitis.

BACKGROUND: The mainstay of treatment for eosinophilic granulomatosis with polyangiitis (EGPA) is systemic corticosteroid therapy; some patients also receive intravenous immunoglobulins, other immunosuppressive agents, and biologics. Mepolizumab, an anti-interleukin-5 monoclonal antibody, induces remission and decreases the daily corticosteroid dose; however, the clinical efficacy of mepolizumab in EGPA and the prognosis with long-term treatment with this drug are unknown. METHODS: Seventy-one EGPA patients were treated at Hiratsuka City Hospital, Japan, between April 2018 and March 2022. We administered mepolizumab for a mean of 2.8 ± 1.7 years to 43 patients in whom remission could not be induced by conventional treatment. After excluding 18 patients who had received mepolizumab for less than 3 years, we classified 15 patients into a "super-responder group" (the daily dose of corticosteroids or other immunosuppressant could be decreased, or the interval between IVIG treatments could be prolonged) and 10 patients into a "responder group" (neither of these changes was achievable). Eosinophil numbers, serum IgG levels, daily doses of corticosteroids and other immunosuppressants, Birmingham Vasculitis Activity Score (BVAS), and relapse frequency before and after mepolizumab initiation were determined. RESULTS: Blood eosinophil count at diagnosis and the lowest serum IgG level before mepolizumab treatment were significantly higher in super-responders than in responders (p < 0.05). In super-responders, the prednisolone dose at last visit on mepolizumab treatment was lower than that before treatment (p < 0.01) and lower than that at last visit in the responders (p < 0.01). In both groups, peripheral blood eosinophil numbers and BVAS were lower after starting mepolizumab than before (p < 0.01). BVAS before mepolizumab (p < 0.05) and at last visit (p < 0.01) were lower in super-responders than in responders. Relapse rates every year after the start of mepolizumab were lower in super-responders than in responder groups (p < 0.01). In super-responders, relapse rates were lower during the 3 years following mepolizumab initiation (p < 0.01) and at last visit (p < 0.01) were significantly lower than after 1 year of treatment. CONCLUSION: Mepolizumab treatment of super-responders sustainably reduced the relapse rate.

A case of eosinophilic polyangiitis with granulomatosis that evolved to cardiac arrest due to advanced atrioventricular block.

Cardiac manifestations are the major cause of mortality in patients with eosinophilic granulomatosis with polyangiitis (EGPA). Among these manifestations in EGPA patients, in the literature, there are fewer reports describing bradycardia in EGPA patients than those describing tachycardia. A 50-year-old woman with a history of childhood-onset asthma. At age 28, she was diagnosed with eosinophilic gastroenteritis without the diagnosis of EGPA and was started on a systemic steroid and had maintenance daily dose of 2.5 mg after gradually tapered. She had experiencing dizziness and palpitations 2 weeks after discontinuation of the steroid treatment. At emergency visit, electrocardiography revealed an advanced atrioventricular block of 3:1 or less. Forty-eight minutes after the start of electrocardiography, only a P wave was observed and cardiac arrest occurred for 9 s and temporary emergency pacing was performed immediately. She was diagnosed as EGPA presenting leukocyte count, 16,500/µL, 42.8% of which were eosinophils and sinusitis in computed-tomography. She could be survival by treatment of steroid, following the patient to withdraw from an external pacemaker. She received prednisolone of 60 mg, intravenous cyclophosphamide and intravenous immunoglobulin. She had relapsed presenting peripheral eosinophilia, abdominal and numbness in the toes of the left leg pain, but not arrythmia after tapered of prednisolone. Following additional steroid pulse, she had an increase of prednisolone and continued by intravenous cyclophosphamide, intravenous immunoglobulin and started mepolizumab. We presented a severe case of EGPA presenting an advanced atrioventricular block into cardiac arrest.

Mite allergen avoidance decreases allergic symptoms in children in Ishinomaki city of Japan after natural disasters.

OBJECTIVE: We investigated the prevalence of asthma, rhinitis, and atopic dermatitis in children, evaluated the mite allergen levels in their bedding after the Great East Japan Earthquake, and assessed changes in allergic symptoms in children and their families after allergen avoidance practices. METHODS: We performed a survey for the International Study of Asthma and Allergies in Childhood (ISAAC) comprising 1109 children, aged 7-8 years, living in Ishinomaki, Japan. We collected responses from 464 children, and in 2016, measured the level of Dermatophagoides group 1 (Der 1) in the bedding of 202 of these children. The intervention group of children attended at least one allergen avoidance seminar. The levels of Der 1 in their bedding were measured, along with changes in allergic symptoms, in 17 children in 2017 and 14 children in 2018. The nonintervention group comprised children who did not attend an allergen avoidance seminar at any time. RESULTS: Of the 464 children who participated in the ISAAC, 50 (10.8%) reported having asthma, 179 (38.8%) allergic rhinitis, and 126 (27.3%) atopic dermatitis. The average level of Der 1 measured in the bedding of the 202 children in 2016 was 295.8 ng/m2. The levels of Der 1 in the intervention group-but not in the nonintervention group-significantly decreased in 2017 and 2018. The symptoms of asthma, allergic rhinitis, and atopic dermatitis in the children of intervention group and their families decreased after allergen avoidance practices. CONCLUSIONS: Allergen avoidance practices relieved allergic symptoms in school children after the Great East Japan Earthquake.

Rituximab and dupilumab improve eosinophilic granulomatosis with polyangiitis with multiple pulmonary thrombi.

BACKGROUND: Eosinophilic granulomatosis with polyangiitis (EGPA) is characterized by a necrotizing vasculitis with tissue and peripheral blood eosinophilia affecting small and medium-sized arteries, capillaries, and veins. Venous thromboembolic events are uncommon in EGPA. Moreover, there are only a few reported cases of EGPA complicated by pulmonary embolism or infarction. CASE PRESENTATION: We report the case of a 43-year-old woman with eosinophilic granulomatosis with polyangiitis and acute respiratory and heart failure due to bilateral pulmonary artery thrombosis and left femoral vein thrombosis 12 years after disease onset. She also had cardiac involvement (myocarditis, pericardial effusion, and diastolic dysfunction), gastrointestinal symptoms, and peripheral neuropathy. The condition was refractory to treatment with systemic corticosteroids, intravenous cyclophosphamide, and mepolizumab, but the thrombosis and associated acute cardiac failure, as well as the cardiac and gastrointestinal symptoms and multiple polyneuropathy, improved after a switch to rituximab. However, the heart failure did not improve sufficiently and the patient continued to need inhaled oxygen at 1 L/min and asthma exacerbations occurred. We then swapped the patient's mepolizumab treatment for dupilumab. Not only did she have no further asthma attacks after switching to dupilumab, but also her vasculitis symptoms improved. Oxygen therapy was discontinued as the heart failure improved 5 months after starting the dupilumab. CONCLUSIONS: This may be the first case report of the successful treatment by rituximab of pulmonary thromboembolism associated with EGPA. In addition, in this patient, treatment with dupilumab was effective not only for the asthma symptoms but also for the symptoms of vasculitis and heart failure.

Indoor Fungal Contamination in Temporary Housing after the East Japan Great Earthquake Disaster.

To understand fungal contamination in the indoor environment of the disaster region, a field survey was performed to measure the number of fungal counts and identify isolates in the indoor air of prefabricated temporary housing, privately independent-housing, and rented apartments flooded by the East Japan Great Earthquake disaster tsunami. As a result, the period with the highest detected fungal count was from the rainy season to summer in independent-housing and rented apartments. Moreover, in the temporary housing, the fungal number increased further in winter as indicated by the maximum fungal-number throughout the measurement period. The detection frequency of Aspergillus species was relatively higher in the indoor air of temporary housing than in typical housing in the non-disaster area. Since Aspergillus is known as an allergenic genus, it requires careful attention to the health risk for residents. The extremely high level of fungal condensation in indoor air possibly occurred due to high relative humidity and loss of heat insulation in the building attics. It is suggested that this problem commonly happened in the cold region including the entire disaster region of the East Japan Great Earthquake.

Association between Temporary Housing Habitation after the 2011 Japan Earthquake and Mite Allergen Sensitization and Asthma Development.

INTRODUCTION: We previously reported an increased prevalence of asthma in adults who lived in temporary housing after the 2011 Great East Japan Earthquake. The goal of the current study was to investigate changes in asthma prevalence and mite-specific immunoglobulin E (IgE) titers in temporary housing residents during 2014-2019. METHODS: By using the Global Initiative for Asthma guidelines, we diagnosed asthma in Ishinomaki city temporary housing residents aged 15 years or older. We then analyzed serum antigen-specific IgE levels to Dermatophagoides farinae (Der f), Dermatophagoides pteronyssinus (Der p), and Aspergillus fumigatus. RESULTS: The prevalence of asthma exceeded 20% across all age-groups throughout the study period. The proportion of study participants with a "positive" antigen-specific IgE titer (i.e., ≥0.35 IUA/mL) was higher in asthmatics than in nonasthmatics for Der f and Der p but not for Aspergillus fumigatus. Among residents ≥50 years old who were diagnosed with asthma, the percentage with a Der f-specific IgE titer ≥0.10 IUA/mL was higher than the proportion with ≥0.35 IUA/mL. Among study participants, asthma onset occurred before the earthquake, during residence in shelters or temporary housing, and (starting in 2016) after moving out of temporary housing. The Der p-specific IgE level was positively correlated with the duration of temporary housing (p < 0.05, r = 0.41) and inversely correlated with the time elapsed since moving out of temporary housing (p < 0.05, r = -0.35). CONCLUSION: Mite allergen sensitization was found in both asthmatic and nonasthmatic temporary housing residents after the 2011 Japan earthquake and tsunami; asthma developed even after subjects moved out of temporary housing.

Clinical Features of Patients with Active Eosinophilic Granulomatosis with Polyangiitis Successfully Treated with Mepolizumab.

BACKGROUND: In some patients with eosinophilic granulomatosis with polyangiitis (EGPA), remission cannot be induced, despite treatment with corticosteroids and immunosuppressants. We evaluated the clinical features of patients with EGPA in whom mepolizumab was effective. METHODS: There were 59 EGPA patients treated at Hiratsuka City Hospital, Japan, between April 2018 and September 2020, and 30 of them received mepolizumab. Twenty (66.7%) experienced a "marked effect" (the daily dose of corticosteroid or immunosuppressant could be decreased, or the interval between intravenous immunoglobulin (IVIG) treatments could be prolonged) and 10 (33.3%) experienced a "weak effect" (these measures were not achieved). Eosinophil numbers, serum IgG levels, daily doses of corticosteroids and immunosuppressants, and the interval between IVIG treatments at diagnosis and before and after mepolizumab initiation were determined. RESULTS: Eosinophil numbers at diagnosis were significantly higher in the marked-effect group than in the weak-effect group (p < 0.05) but not before mepolizumab initiation or at the last visit. Birmingham Vasculitis Activity Scores (BVASs) before mepolizumab initiation (p < 0.05) and at last visit (p < 0.01), and frequency of relapse before treatment initiation (p < 0.05) were significantly higher, and the serum IgG level before mepolizumab treatment was significantly lower in the weak-effect group than in the marked-effect group. The weak-effect group received higher doses of corticosteroids, even if the corticosteroid dose could be reduced for a while after mepolizumab initiation. CONCLUSION: High peripheral blood eosinophil numbers at EGPA diagnosis were suggestive of a positive clinical response to mepolizumab.

Factors associated with pneumococcal vaccine uptake in elderly subjects referred to the respiratory department.

Streptococcus pneumoniae is the most common pathogen for community-acquired pneumonia and is also common in nursing and healthcare-associated pneumonia. Pneumococcal vaccine shows clinical benefit and 23-valent pneumococcal polysaccharide vaccine (PPSV23) has been introduced in a routine immunization program in Japan. However, uptake of PPSV23 remains low, at 40%. One opportunity for capturing unvaccinated subjects is hospital referrals. Identifying factors associated with pneumococcal vaccination among referred subjects is thus important so that pulmonologists can maximize the capture of unvaccinated subjects. We retrospectively reviewed the records of subjects with a first referral to the Department of Respiratory Medicine at Hiratsuka City Hospital from September 2017 to March 2018. Subjects who were ≥65 years old and lived in Hiratsuka were included in this study. We compared the backgrounds of subjects and investigated factors associated with pneumococcal vaccination. A total of 142 individuals were included in this study and the pneumococcal vaccination rate was 44.4% (95% confidence interval (CI), 36.0-52.9%). Of these, 127 subjects regularly visited clinics and/or hospitals for any diseases and their pneumococcal vaccine rate was 44.1% (95%CI, 35.3-53.2%). In multivariate analysis, chronic respiratory diseases (odds ratio 5.7; 95%CI, 2.2-14.9, P<0.001) and receipt of PPSV23 notification (odds ratio 8.5; 95%CI, 2.5-29.0, P<0.001) were positively associated with pneumococcal vaccination. In conclusion, chronic respiratory diseases and receipt of PPSV23 notification were positively associated with pneumococcal vaccination. However, pneumococcal vaccination rates remain relatively low, even in subjects regularly visiting clinics and/or hospitals.

Familial Eosinophilic Granulomatosis with Polyangiitis in a Sister and Brother.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a vasculitis characterized by an abnormally high number of eosinophils in the peripheral blood and tissues. EGPA is an extremely rare disorder, with an incidence of 0.5 to 3.7 new cases per million people per year and an overall prevalence of 2.4 to 14 per million adults. There is little knowledge about the genetic factors that influence this disease. There are only two reports of familial EGPA: one in Japan and one in Turkey. We herein report a third case of familial EGPA in a brother and sister who were negative for myeloperoxidase-antineutrophil cytoplasmic antibodies.

[EVALUATION OF A MOTOR AND SENSORY DISTURBANCE QUESTIONNAIRE FOR PATIENTS WITH EOSINOPHILIC GRANULOMATOSIS WITH POLYANGIITIS].

BACKGROUND AND AIMS: It is difficult to evaluate neurological signs of multiple mononeuritis (MM) in patients with eosinophilic granulomatosis with polyangiitis (EGPA). We created a new questionnaire about motor and sensory disturbances in EGPA and investigated whether the questionnaire would be a useful tool in the management of MM in EGPA patients. METHODS: We classified 40 EGPA patients attending Hiratsuka City Hospital into two groups, namely 30 who were treated with intravenous immunoglobulin (IVIG) and 10 who achieved remission by conventional treatment without IVIG. We created a questionnaire for the evaluation of motor and sensory disturbance in EGPA (ANCA related.com). In patients who received IVIG, we evaluated motor and sensory disturbance scores at disease onset, before IVIG, 1 week and 1 month after the end of IVIG. In patients treated without IVIG, we evaluated these scores at disease onset and at the time of the latest examination. RESULTS: The total motor disturbance score at disease onset was significantly lower in EGPA patients who received IVIG than in those who did not receive it. Disease duration was significantly inversely correlated with the change in the sensory disturbance ratio, but not with the motor disturbance ratio. The motor disturbance ratio was significantly correlated with the manual muscle test improvement ratio. In patients who received IVIG, the total motor disturbance score increased significantly, and the total sensory disturbance score decreased significantly, 1 month after IVIG. CONCLUSION: By using the questionnaire we could evaluate changes in motor and sensory disturbance after IVIG treatment in patients with EGPA. The questionnaire should be useful in the management of MM in EGPA patients.

Innate immune response reflects disease activity in eosinophilic granulomatosis with polyangiitis.

BACKGROUND: Eosinophilic granulomatosis with polyangiitis (EGPA) is a disease characterized by allergic granulomatosis, necrotizing vasculitis, and peripheral blood eosinophilia. Interleukin (IL)-33, thymic stromal lymphopoietin (TSLP), and type 2 innate lymphoid cells (ILC2) are involved in the innate and type 2 immune responses in EGPA. However, the relationships among these molecules and the mechanisms underlying the development of EGPA remain unknown. OBJECTIVE: We investigated the relationships among peripheral blood eosinophil count, serum IL-33 and TSLP concentration, and peripheral blood ILC2 count in patients with EGPA, chronic eosinophilic pneumonia (CEP), or bronchial asthma (BA). METHODS: We recruited 86 patients with EGPA in three groups (remission, relapse, and onset), 25 patients with CEP at active or inactive stages of disease, and 11 patients with BA. In patients with EGPA, CEP, or BA, serum IL-33, sST2, and TSLP concentrations were determined using ELISA and peripheral blood ILC2 counts (as Lin-1- CD127+ CRTH2+ cells) were determined using flow cytometry. RESULTS: Peripheral blood eosinophil count or ILC2 count, and serum sST2 or TSLP concentration were higher in patients with EGPA at onset than in those with EGPA at relapse or remission, or in those with BA or CEP. Serum IL-33 concentration was higher in patients with EGPA at relapse than in those with EGPA at onset or remission, or in those with BA or CEP. In a logistic regression model, EGPA disease activity was correlated with serum IL-33 concentration and peripheral blood ILC2 count, but not daily systemic and inhaled corticosteroid dose or immunosuppressant use. Eosinophil count was correlated with peripheral blood ILC2 count and serum TSLP concentration, but not serum IL-33 concentration. CONCLUSIONS: Increased peripheral blood ILC2 count and serum IL-33 concentration were associated with disease activity in EGPA. Increases in serum IL-33 concentration may indicate the presence of active vasculitis rather than peripheral or tissue eosinophilia.

Low Variability in Peak Expiratory Flow Predicts Successful Inhaled Corticosteroid Step-Down in Adults with Asthma.

BACKGROUND: The prognosis for patients beyond 1 year after reduction of their inhaled corticosteroid (ICS) dose remains unknown. Predictive factors that can be evaluated before the initiation of asthma treatment or at ICS dose reduction are unknown. METHODS: We prospectively studied 223 patients in 6 hospitals in the National Hospital Organization of Japan during the 36 months after 50% reduction of their daily ICS dose. All patients recorded their morning and evening peak expiratory flows (PEFs) in their diaries. Lung function, bronchial hyperresponsiveness, fractional nitric oxide levels, number of eosinophils in sputum, and serum IgE levels were measured in most patients. Serum levels of IL-10, IL-33, and thymic stromal lymphopoietin before ICS dose reduction were measured in all patients. RESULTS: During the 36-month study period, asthma control was retained in 127 (59.6%) of the 213 enrolled patients who underwent ICS dose reduction. Multivariate logistic regression analysis revealed that, at the initiation of dose reduction, the factors most predictive of maintenance of asthma control after ICS dose reduction were a low serum IL-33 level (P < .01), low PEF variability over 1 week (P = .014), childhood onset of asthma (at age <10 years) (P = .03), and high serum IL-10 level (P = .035). CONCLUSIONS: We demonstrated that low PEF variability over 1 week, high serum IL-10 level, and low serum IL-33 concentration were useful factors for predicting that an adult's asthma will remain in control for months to years after a 50% reduction in the daily ICS dose.

Allergic Bronchopulmonary Mycosis due to Exposure to Eurotium herbariorum after the Great East Japan Earthquake.

BACKGROUND: Indoor mold levels typically increase after natural disasters, flooding, and water damage. Eurotium herbariorum is the sexual stage of Aspergillus glaucus. Case Presentation A 66-year-old, Japanese male, ex-smoker had been diagnosed with bronchial asthma when he was five years old; he achieved remission at the age of 13 years. He was displaced from his home during the Great East Japan Earthquake on March 11, 2011 and moved to temporary housing in Miyagi Prefecture in June 2011. He experienced the first episode of chest tightness, coughing, and wheezing in February 2012, when he again was diagnosed as having bronchial asthma. Mycofloral surveillance detected high counts of Eurotium in the air of his bedroom, kitchen, and living room, with a maximal fungal count of 163,200 colony-forming units per cubic meter (CFU/m3). Although Cladosporium and Penicillium typically predominate in the indoor air of residential dwellings, only low levels of these organisms were present in the patient's home. Morphologic identification confirmed the isolates as E. herbariorum. The patient had positive reactions to E. herbariorum in skin prick testing and the presence of antigen-specific precipitating antibodies to E. herbariorum. Computed tomography of the chest in August 2013 revealed central bronchiectasis and bronchial wall thickening. The patient experienced late reactions after provocation testing with E. herbariorum. CONCLUSION: This report presents the rare case of a patient who developed allergic bronchopulmonary mycosis (ABPM) due to exposure to E. herbariorum during temporary housing after the Great East Japan Earthquake.

Longterm Prognosis of 121 Patients with Eosinophilic Granulomatosis with Polyangiitis in Japan.

OBJECTIVE: We investigated the risk factors for relapse or prognosis of eosinophilic granulomatosis with polyangiitis (EGPA) in Japanese patients presenting to our hospital. METHODS: From June 1999 through March 2015, we retrospectively recruited 121 patients with EGPA according to the American College of Rheumatology criteria. Frequent relapse was defined as disease occurrence at least once every 2 years after a period of initial remission. The study endpoint was the last examination performed. We used multiple logistic regression to analyze risk factors for relapse or survival in EGPA. RESULTS: Gastrointestinal (GI) involvement with both abnormalities on endoscopy and biopsy (p < 0.01) and symptoms; myocardial involvement with both abnormalities on 1 or more cardiac investigations and symptoms (p < 0.01); and treatment at initial or maintenance with immunosuppressants (p < 0.01) or administration of intravenous immunoglobulin (IVIG; p < 0.01) were associated significantly more often with frequent relapse than with infrequent. Overall 5-, 10-, and 20-year survival rates were 91.1%, 83.7%, and 68.6%, respectively. Survival in EGPA was associated with age of onset < 65 years. Age at onset of EGPA was the only significant predictor of survival (p < 0.01). Myocardial or GI tract involvement did not affect mortality risk. CONCLUSION: Patients with myocardial or GI tract involvement had frequent relapses, but these conditions were not reflected in increased mortality. Treatment with immunosuppressants or IVIG in addition to corticosteroids might have improved the prognosis in Japanese patients with EGPA.
