Teduglutide-induced acute gastric mucosal necrosis in short bowel syndrome with hepatorenal failure: Case report.

INTRODUCTION: Short bowel syndrome (SBS) resulting from acute aortic dissection (AAD)-induced visceral malperfusions leads to chronic intestinal failure (CIF), necessitating patients to adopt home parenteral nutrition to prevent malabsorption. Teduglutide (TED), a glucagon-like peptide-2 analog, is a promising pharmacotherapy for intestinal rehabilitation that reduces parenteral support and improves the quality of life. Gastric mucosal necrosis, a rare gastrointestinal disorder, had never been observed as an adverse event relevant to this drug. We report a case of mucosal necrosis in the stomach after TED treatment for SBS-CIF with hepatorenal failure. PRESENTATION OF CASE: A 68-year-old Japanese man who underwent massive intestinal resection for AAD experienced malnutrition and diarrhea caused by SBS-CIF. The patient received TED to improve intestinal absorption and entero-hepatic circulation besides controlling infectious diseases. Endoscopy showed mucosal hyperplasia in the stomach and duodenum 1.5 months after TED administration. The patient consented to enteral nutrition via a nasogastric tube because of anorexia. The nutritional status gradually improved after initiating enteral feeding. However, the patient experienced hematemesis 13 days after enteral feeding, and endoscopy revealed acute gastric mucosal necrosis, followed by fatal septic shock. DISCUSSION: For patients with SBS, TED is expected to increase intestinal absorption through epithelial proliferation. When SBS is accompanied by multiple ischemic organ failure, TED therapeutic effects remain unclear as malnutrition-associated infectious diseases are refractory, and many underlying mechanisms can be involved. CONCLUSION: TED administration should be deliberately considered for patients with SBS-CIF and multiple organ failure experiencing uncontrolled systemic infection.

Serum Cytokine Changes in a Patient with Chronic Pulmonary Aspergillosis Overlapping with Allergic Bronchopulmonary Aspergillosis: A Case Report.

Allergic bronchopulmonary aspergillosis (ABPA) and chronic pulmonary aspergillosis (CPA) are diseases caused by Aspergillus infection, and CPA can develop from ABPA in some cases. We herein report a patient with CPA overlapping with ABPA. Serum cytokine levels were evaluated at 4 time points: the ABPA diagnosis, CPA diagnosis, 6 months after the start of voriconazole (VRCZ), and 12 months after re-administration of VRCZ. Interleukin (IL)-13 levels decreased upon glucocorticoid treatment, whereas IL-25 and IL-33 levels decreased rapidly with the initiation of antifungals. Early antifungal therapy may be important to control disease progression and prevent CPA overlap.

A Novel Hidden Stitching Method for Preventing Complications in Laparoscopic Hernia Repair.

PURPOSE: Barbed suture provides a rapid and effective method for closure in minimally invasive surgery. However, postoperative complications involving barbed suture have been reported in recent years. The aim of this study is to introduce a novel hidden stitching technique for peritoneal closure in laparoscopic hernia repair. METHOD: This study retrospectively analyzed the data of patients with laparoscopic transabdominal preperitoneal patch (TAPP). In the hidden stitch (HS) group, the barbed suture was hidden on the dorsal side of the peritoneum and two stitches were returned in the opposite direction after the suture reached the end point. In the non-hidden stitch (NHS) group, the barbed sutured was exposed in the peritoneal cavity with a tail stump of approximately 10 mm preserved to prevent the peritoneal sutures from loosening. RESULTS: Twenty-seven patients in the HS group were compared with 53 in the NHS group. There were no differences in age, body mass index, surgical bleeding, or length of hospital stay between the two groups. The peritoneal defect closure time was slightly longer (3 min) in the HS group, but the overall operation time was not significantly extended. There were 8 cases of postoperative complications (P = .035) including 4 cases of bowel obstruction due to the tail of the barbed thread penetrating the small intestine mesenteric and two cases of seroma. There were no postoperative complications in the HS group. CONCLUSIONS: The hidden stitch method is a safe and feasible peritoneal closure technique that may reduce postoperative complications caused by barbed suture in laparoscopic hernia repair.

Evaluation of a Triage Checklist for Mild COVID-19 Outpatients in Predicting Subsequent Emergency Department Visits and Hospitalization during the Isolation Period: A Single-Center Retrospective Study.

Managing mild illness in COVID-19 and predicting progression to severe disease are concerning issues. Here, we investigated the outcomes of Japanese patients with mild COVID-19, and identified triage risk factors for further hospitalization and emergency department (ED) visits at a single tertiary hospital. A triage checklist with 30 factors was used. Patients recommended for isolation were followed up for 10 days for subsequent ED visits or hospital admission. Overall, 338 patients (median age, 44.0; 45% women) visited the clinic 5.0 days (median) after symptom onset. Thirty-six patients were immediately hospitalized following triage; others were isolated. In total, 72 non-hospitalized patients visited the ED during their isolation, and 30 were hospitalized after evaluation for oxygen desaturation. The median ED visit and hospitalization durations after symptom onset were 5.0 and 8.0 days, respectively. The checklist factors associated with hospitalization during isolation were age > 50 years, body mass index > 25 kg/m2, hypertension, tachycardia with pulse rate > 100/min or blood pressure > 135 mmHg at triage, and >3-day delay in hospital visit after symptom onset. No patients died. Altogether, 80% of patients with mild COVID-19 could be safely isolated at home. Age, BMI, underlying hypertension, date after symptom onset, tachycardia, and systolic blood pressure at triage might be related to later hospitalization.

Serum Cytokines Usefulness for Understanding the Pathology in Allergic Bronchopulmonary Aspergillosis and Chronic Pulmonary Aspergillosis.

Allergic bronchopulmonary aspergillosis (ABPA) and chronic pulmonary aspergillosis (CPA) are important fungal infections caused by Aspergillus species. An overlap of ABPA and CPA has been reported; therefore, it is critical to determine whether the main pathology is ABPA or CPA and whether antifungals are required. In this study, we investigated whether the serum cytokine profile is useful for understanding the pathology and for differentiating between these diseases. We compared the various serum cytokine levels among healthy subjects and patients diagnosed with asthma, ABPA, or CPA at Nagasaki University Hospital between January 2003 and December 2018. In total, 14 healthy subjects, 19 patients with asthma, 11 with ABPA, and 10 with CPA were enrolled. Interleukin (IL) -5 levels were significantly higher in patients with ABPA than in those with CPA, and IL-33 and tumor necrosis factor (TNF) levels were significantly higher in patients with CPA than in those with asthma (p < 0.05, Dunn's multiple comparison test). The sensitivity and specificity of the IL-10/IL-5 ratio (cutoff index 2.47) for diagnosing CPA were 70% and 100%, respectively. The serum cytokine profile is useful in understanding the pathology of ABPA and CPA, and the IL-10/IL-5 ratio may be a novel supplemental biomarker for indicating the pathology of CPA.

Preoperative respiratory intervention eliminated the operation cancelations of lobectomy surgery.

In Nagasaki University Hospital, the patients undergoing surgery with abnormal respiratory function have been automatically referred to specialized clinic by Medical Support Center (MSC) since July 2016 to reduce surgery cancellations due to insufficient preoperative evaluation. Whether the MSC system decreased post-hospital surgery cancellation, variance rate, or length of hospital stays in patients received "lobectomy" were retrospectively compared between Period A (n = 264, before MSC introduction) and Period B (n = 264, after MSC introduction). Four patients' operations were cancelled after hospitalization in Period A, while 0 patients in Period B (p < 0.05). The length of hospital stay, operation time, anesthesia time, and postoperative extubation oxygen administration time were all shorten in Period B significantly. "Period B", "operation time", and "postoperation oxygenation time" were independent factors for "hospital days", but chronic obstructive pulmonary disease or age were not. The preoperative intervention eliminated the operation cancellation. Preoperative MSC interventions may have contributed to the reduction in hospital days even for the patients with pulmonary dysfunction.

Determining Response to Treatment for Drug-Induced Bronchocentric Granulomatosis by the Forced Oscillation Technique.

Anti-tumor necrosis factor alpha (TNFα) therapy is widely used to treat various inflammatory conditions. Paradoxically, there are several case reports describing the development of bronchocentric granulomatosis treated with TNFα inhibitors, and it is difficult to determine the effect of treatment using conventional spirometry because the lesions are located in small airways. However, it has been reported that the forced oscillation technique (FOT) is useful in the evaluation of small airway disease in bronchial asthma or chronic obstructive pulmonary disease. We performed the FOT to determine the effect of treatment on bronchocentric granulomatosis and found it to be useful. We report the case of a 55-year-old female with ulcerative colitis who was treated with golimumab and who developed bronchocentric granulomatosis as a sarcoid-like reaction to golimumab. She was successfully treated with prednisone, and the treatment efficacy was confirmed by the FOT. The FOT may be useful in the evaluation of small airway disease in bronchocentric granulomatosis. This case may help inform clinicians of the usefulness of the FOT to assess small airway disease in various diseases.

Bowel obstruction and perforation secondary to barbed suture after minimally invasive inguinal hernia repair: report of two cases and literature review.

BACKGROUND: Laparoscopic transabdominal preperitoneal patch (TAPP) is now commonly used in the repair of inguinal hernia. Barbed suture can be a fast and effective method of peritoneal closure. We report two rare cases of small bowel obstruction and perforation caused by barbed suture after TAPP. CASES: Patient 1 is a 45-year-old man who underwent laparoscopic repair of a right inguinal hernia. Barbed suture was used to close the peritoneal defect. At 47 days after the operation, he was diagnosed with a small bowel obstruction caused by an elongated tail of the barbed suture. Emergency laparoscopic exploration was performed for removal of the embedded suture and detorsion of the volvulus. The second patient is a 50-year-old man who was admitted with a small bowel perforation one week after TAPP herniorrhaphy. Emergency exploration revealed that the tail of the barbed suture had pierced the small intestine, causing a tiny perforation. After cutting and releasing the redundant tail of the barbed suture, the serosal and muscular defect was closed with 2 absorbable single-knot sutures. Both patients have recovered well. Finally, we searched the PubMed database and reviewed the literature on the effectiveness and safety of barbed suture for TAPP. CONCLUSIONS: Surgeons should understand the characteristics of barbed suture and master the technique of peritoneum closure during TAPP in order to reduce the risk of bowel obstruction and perforation.

Laparoscopic surgical treatment for hydrocele of canal of Nuck: A case report and literature review.

BACKGROUND: Hydrocele of canal of Nuck (HCN) is a rare disease in adult female. The diagnosis and treatment of HCN is still a challenge for surgeons. CASE PRESENTATION: A 56-year-old female presented with recent onset of occasional pain during exercise and an asymptomatic left groin swelling. Ultrasonography results were suspicious for left inguinal hernia incarceration and computed tomography (CT) scan showed no intestinal obstruction, which was considered as HCN. Laparoscopic hydrocelectomy of the HCN and a routine laparoscopic hernia repair via the transabdominal preperitoneal (TAPP) approach were performed. Postoperative pathology showed no malignant lesions or endometriosis. CONCLUSIONS: The preoperative diagnosis of HCN is extremely important. Surgeons should choose appropriate surgical methods for different anatomical HCNs based on the preoperative diagnosis.

Laparoscopic assisted hydrocelectomy of the canal of Nuck: a case report.

BACKGROUND: Accurate diagnosis and complete resection of hydrocele of canal of Nuck (HCN) is still a challenge for surgeons. CASE PRESENTATION: A 28-year-old woman presented with a suspected inguinal hernia due to swelling in her right groin and was introduced for surgical treatment. Computed tomography scan revealed local cyst formation in the right groin and eliminated intestinal incarceration. In order to further confirm the diagnosis, we used laparoscopic exploration; after excluding a combined hernia, HCN was surgically removed using a conventional anterior peritoneal approach and a mesh patch repair was not needed. Postoperative pathology results showed no endometriosis or malignancy. CONCLUSIONS: Laparoscopic assisted anterior approach provides both an accurate intraoperative diagnosis and a quick complete resection of HCN; it is the preferred treatment for women of childbearing age with pure HCN.

Evacuatory Dysfunction after Stapled Hemorrhoidopexy: A Case Report of Rectal Pocket Syndrome.

A 60 year-old male was referred to the authors' hospital with a persistent urge to defecate. The patient had undergone stapled hemorrhoidopexy (SH) for the treatment of prolapsed hemorrhoids approximately 10 years earlier. He started to have difficulty with defecation and a false sense of urgency shortly after the surgery. Computed tomography showed a diverticulum-like fistula along the circumference of the rectum. Colonoscopy revealed communication between the diverticular cavity and the rectal lumen. The cavity contained a thumbnail-sized fecalith. When the fecalith was removed, the patient's urge to defecate dissipated. The patient was diagnosed with rectal pocket syndrome secondary to SH. The lower rectum was transected, and the remaining rectum and the anal canal were anastomosed by manual suture. Temporary ileostomy with double orifices was performed. The ileostomy was closed 3 months later. The patient experienced no subsequent difficulty with defecation or urgency.

Comparison of 12-Week Additional Effect Features of Formoterol Co-Inhalation and Tulobuterol Patch on Budesonide Inhalation in Elderly Patients With Asthma.

BACKGROUND: For asthma strategy, to avoid the aggravation of bronchial inflammation and contraction, the long acting beta agonist (LABA) addition on inhaled corticosteroids (ICS) has been recommended. OBJECTIVES: To know whether there is any clinical difference between the additional efficacies of Formoterol (FOR) and Tulobuterol (TUL) onto Budesonide (BUD) may be useful for the elderly patients' asthma treatment strategy. METHODS: Eighteen outpatients with mild to moderate bronchial asthma with FEV1.0% < 80% treated by intermediate ICS dosages visited Respiratory Division of Nagasaki University Hospital or Isahaya General Hospital, Japan Community Health care Organization were subjected, and were randomly assigned (9 cases per group) to either the FBC group (BUD/FOR 160/4.5 µg, 2 inhalations twice daily) or BUD + TUL group (BUD 200 mcg: 2 inhalations twice daily + TUL 2 mg daily) and were compared in parallel with 2 arms for 12 weeks prospectively. Peak expiratory flow, forced expiratory volume in 1 second, impulse oscillometry (IOS), fractional exhaled nitric oxide (FeNO), Asthma Control Questionnaire, mini-Asthma Quality of Life Questionnaire (mini-AQLQ), and occurrence of adverse reactions were compared. RESULTS: The "Fres" of IOS was improved in FBC group (p = 0.03). The "emotion" domain of mini-AQLQ was improved in BUD + TUL group (p = 0.03). CONCLUSION: By changing the drug formulation, the patch was superior in terms of satisfaction, but it was thought that the inhaled combination was superior in improving the respiratory function itself. It is necessary to pay attention to the characteristics of the patient when selecting treatment.

Liposomal Amphotericin B Fosters the Corticosteroids' Anti-inflammatory Effect on Murine Allergic Bronchopulmonary Aspergillosis Model Airways.

Fungus is an antigen for bronchial asthma causing allergic bronchopulmonary mycosis (ABPM). As a therapy other than corticosteroids, itraconazole (ITCZ) is known to suppress the allergic inflammation induced by Aspergillus fumigatus (Af). However, the efficacy of liposomal amphotericin B (LAMB) with/without corticosteroid on ABPM is unknown. Mice sensitized to Dermatophagoides farinae (Df) allergen were intranasally infected with Af (DfAf group). After the infection, corticosteroid (dexamethasone (Dex)) was administered for 5 days (DfAf/Dex group). The effects of ITCZ or LAMB with/without Dex were also evaluated. Pathologically, Dex and LAMB combination treatment decreased the allergic inflammation evidently. The bronchoalveolar lavage fluid (BALF) concentrations of IL-5, IL-13, and MIP-2 were significantly elevated in DfAf mice compared with control mice (p < 0.05, each). In DfAf mice, ITCZ and LAMB significantly decreased the elevation of MIP-2 (p < 0.05 vs the DfAf group). The addition of both Dex and LAMB suppressed the MIP-2 elevation in DfAf mice (p < 0.05 vs the Df/Af/Dex/LAMB group), but the addition of Dex and ITCZ did not (DfAf/Dex/ITCZ group). None of Dex, ITCZ, or LAMB decreased pulmonary IL-13 concentration. It was suggested that combination of antifungal drugs and corticosteroid enhanced the suppressing effect of airway inflammations. This finding will give a hope for the treatment of severe fungus-related asthma.

Fluctuation of Hepatic Focal Nodular Hyperplasia Size with Oral Contraceptives Use.

BACKGROUND Focal nodular hyperplasia (FNH) of the liver is a rare benign nodular lesion that arises in women of reproductive age. Although a role of female hormones has been suggested, their influence on the course of FNH has remained controversial. CASE REPORT A 44-year-old woman with a 12-year history of oral contraceptive use was referred to our hospital for examination of an asymptomatic liver mass (3 cm in diameter) identified by computed tomography. We diagnosed FNH using imaging methods and fine-needle biopsy. Oral contraceptives were discontinued because the mass increased over a period of 21 months. Four months later, the mass had decreased in size, indicating that FNH can spontaneously regress when oral contraceptives are discontinued. CONCLUSIONS Discontinuation of oral contraceptives use can reduce the size of FNH, as in this case.

Pulmonary Artery Sarcoma Overexpressing Platelet-derived Growth Factor Receptor α.

Pulmonary artery sarcoma is highly malignant and easily metastasizes to the systemic organs. Both the introduction of novel diagnostic procedures and the development of new treatment modalities are required to achieve long-term survival. Several studies have shown that platelet-derived growth factor receptor α (PDGFRα) gene amplification is frequently observed in pulmonary artery sarcoma. PDGFRα is known to be involved in cell proliferation in certain malignancies. PDGFRα may become a potential biological marker in pulmonary artery sarcoma. We report a case in which a diagnosis of pulmonary artery sarcoma overexpressing PDGFRα was made using endovascular catheter biopsy following positron emission tomography with integrated computed tomography (PET/CT) scans.

Anal Canal Adenocarcinoma in a Patient with Longstanding Crohn's Disease Arising From Rectal Mucosa that Migrated From a Previously Treated Rectovaginal Fistula.

BACKGROUND This study reports the pathogenesis of anal canal adenocarcinoma in a patient with longstanding Crohn's disease (CD). CASE REPORT A 50-year-old woman with a 33-year history of CD presented with perianal pain of several months' duration. She had been treated surgically for a rectovaginal fistula 26 years earlier and had been treated with infliximab (IFX) for the previous 4 years. A biopsy under anesthesia revealed an anal canal adenocarcinoma, which was removed by abdominoperineal resection. Pathological examination showed that a large part of the tumor consisted of mucinous adenocarcinoma at the same location as the rectovaginal fistula had been removed 26 years earlier. There was no evidence of recurrent rectovaginal fistula, but thick fibers surrounded the tumor, likely representing part of the previous rectovaginal fistula. Immunohistochemical analysis using antibodies against cytokeratins (CK20 and CK7) revealed that the adenocarcinoma arose from the rectal mucosa, not the anal glands. CONCLUSIONS Mucinous adenocarcinoma can arise in patients with CD, even in the absence of longstanding perianal disease, and may be associated with adenomatous transformation of the epithelial lining in a former fistula tract.

Usefulness of antiemetic therapy with aprepitant, palonosetron, and dexamethasone for lung cancer patients on cisplatin-based or carboplatin-based chemotherapy.

PURPOSE: The purpose of the study is to investigate the usefulness of the triplet regimen comprising aprepitant, palonosetron, and dexamethasone in patients treated with highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC). METHODS: Patients with lung cancer (aged 65.8 ± 8.4 years) who received carboplatin-based MEC and those treated with cisplatin-based HEC were enrolled. The antiemetic regimen for both types of chemotherapy consisted of aprepitant, palonosetron, and dexamethasone based on the May 2010 guidelines prepared by the Japan Society of Clinical Oncology. The incidence of chemotherapy-induced nausea and vomiting (CINV) and the use of salvage treatment were assessed. The primary endpoints were the percentage of patients with a complete response (CR: no nausea and no salvage treatment) during the entire study period (5 days) after chemotherapy, during the acute phase (day 1), and during the delayed phase (days 2-5). RESULTS: CR rates for the entire period were 86 and 71% in patients receiving carboplatin-based and cisplatin-based chemotherapy, respectively. CR rates were respectively 98 and 100% in the acute phase versus 87 and 71% in the delayed phase. Most of the patients could ingest food throughout the entire period after chemotherapy. Assessment of various risk factors for acute and delayed CINV (gender, age, prior vomiting due to antineoplastic therapy, prior experience of motion sickness, and history of drinking) revealed no significant influence of these factors on the CR rate for the entire period in patients receiving either carboplatin-based or cisplatin-based chemotherapy. CONCLUSION: The present triple therapy can be recommended for supporting both carboplatin-based and cisplatin-based chemotherapy regimens.

Clearance of Aspergillus fumigatus is impaired in the airway in allergic inflammation.

BACKGROUND: Aspergillus fumigatus (Af) sometimes colonizes and persists within the respiratory tree in some patients with asthma. To date, the precise reasons why the clearance of Af is impaired in patients with asthma remain unknown. OBJECTIVE: To characterize the effects of allergic airway inflammation on clearance of Af. METHODS: Control and Dermatophagoides farinae (Df) allergen-sensitized BALB/c mice were intranasally infected with Af. After 2 and 9 days of infection, the pathology, fungal burden, and cytokine profile in lung tissue were compared. In a different set of experiments, the phagocytotic activity of alveolar macrophages and the expression of their pathogen recognition receptors also were determined. RESULTS: The Af conidia and neutrophilic airway inflammation disappeared by day 9 after infection in control mice. In Df-sensitized mice, Af conidia and neutrophilic and eosinophilic airway inflammation persisted at day 9 after infection. Compared with control mice, Df allergen-sensitized mice showed significant increases in interleukin (IL)-5 and decreases in IL-12 and interferon-γ in lung tissues at day 2 after infection. Most importantly, compared with Af-infected non-Df-sensitized mice, IL-17 in lung tissues was significantly decreased in Df allergen-sensitized Af-infected mice at day 2 after infection but was significantly increased at day 9. Alveolar macrophages isolated from Df allergen-sensitized mice exhibited significant decreases in phagocytotic activity and expression of Toll-like receptor-4 and dectin-1 compared with those from control mice. CONCLUSION: In the airway of patients with allergy, T-helper cell type 2-dominant immunity potentially affects the expression of pathogen recognition receptors and attenuates cellular defense against Af. Prolonged IL-17 production also could play an important role.

Cysteinyl leukotriene receptor antagonist regulates allergic airway inflammation in an organ- and cytokine-specific manner.

BACKGROUND: Cysteinyl leukotrienes (cys-LTs) are very important factors in the pathophysiology of bronchial asthma. Cys-LT receptor antagonists (LTRAs) decrease allergic airway inflammation. The aim of the present study was to determine the differential effects of LTRAs and corticosteroids on allergic airway inflammation and allergen-specific cytokine production from lymphoid tissues using a murine model of asthma. MATERIAL AND METHODS: Four groups of female BALB/c mice [control (Cont); Dermatophagoides farinae allergen-sensitized (AS); pranlukast (Prl), an LTRA-treated AS; and dexamethasone (Dex)-treated AS] were examined. Lung pathology and cytokine production by prepared mononuclear cells isolated from mediastinal lymph nodes (MLNs) and spleen were compared among these groups. RESULTS: AS mice exhibited allergic airway inflammation and significant increases in allergen-specific Th1 and Th2 cytokines in MLNs and spleen. Prl-treated mice showed significant attenuation of allergic airway inflammation concomitant with reduction of Th2 cytokines and IFN-g in MLNs but not in spleen. In contrast, Dex significantly decreased Th1 and Th2 cytokines in MLNs and also decreased them (except IL-13 and IL-2) in spleen. CONCLUSIONS: The inflammatory effects of cys-LTs could differ in lymphoid organs. LTRAs potentially regulate allergic airway inflammation in an organ- and cytokine-specific manner, while systemic corticosteroid shows nonspecific effects.

Dissociation between sensitizing and colonizing fungi in patients with allergic bronchopulmonary aspergillosis.

BACKGROUND: Because allergic bronchopulmonary aspergillosis (ABPA) does not require the presence of Aspergillus fumigatus for diagnosis, serological and radiological findings without cultures usually confirm this condition. OBJECTIVE: To determine which fungi colonize the airways of patients with definitive ABPA. METHODS: We enrolled 11 patients (ages 57.5 ± 17.1 years; male: female, 4:7) with ABPA diagnosed by serological and radiological criteria. Fungi colonizing the airway were identified from mucous plugs that were naturally expectorated or obtained by fiberoptic bronchoscopy. RESULTS: Aspergillus spp. (n = 8) was the most frequently isolated, followed by Schizophyllum commune (n = 4), Candida albicans (n = 2), Rhizopus oryzae (n = 1), and Penicillium spp. (n = 1). Among the Aspergillus spp., A. niger, A. terreus, and A. sydowii were more frequently isolated (total, n = 6) than A. fumigatus (n = 2). Many patients were sensitized with several fungi in addition to Aspergillus, which were dissociated with airway-colonizing fungi. CONCLUSION: Multiple fungal species can colonize the airway, and dissociation between colonizing and sensitizing species frequently occurs in definitive ABPA. Considering the increased prevalence of azole-resistant Aspergillus spp., administering antifungal drugs that target A. fumigatus without identifying which fungal species colonize the airway might be problematic.
