Objective: To investigate the clinical characteristics of Aspergillus fumigatus(A.f)-sensitized asthma and allergic bronchopulmonary aspergillosis (ABPA), which provides a foundation for the diagnosis and differential diagnosis of A.f-sensitized asthma and ABPA, as well as the prevention of ABPA. Methods: This was a single-center retrospective case-control study. Collected the clinical data of patients who visited the Department of Respiratory and Critical Care Medicine, Zhongnan Hospital of Wuhan University from December 2018 to May 2022.A total of 122 patients were included, including 64 males (52.5%) and 58 females (47.5%).The age range was 3 to 89 years.The median age was 44 years.The average age was 41.8 years.The patients were divided into three groups (48 ABPA, 35 A.f-sensitized asthma and 39 HDM-sensitized asthma).Analyzed the differences and correlations among clinical indicators in the three groups, and evaluated the risk factors for the development of ABPA in A.f-sensitized asthma.For statistical analysis, metrological data was tested by t-test or Wilcoxon Mann-Whitney. Classification variables by chi-square test or Fisher's exact test. Pearson correlation analysis for normal distribution data.Spearman correlation analysis for skewed distribution data. Influencing factor analysis was performed using multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve was made, the area under the ROC curve (AUC) was calculated, and the sensitivity and specificity of the model were evaluated. Results: Compared with patients with A.f-sensitized asthma, the fractional exhaled nitric oxide (FeNO) [75.00(52.00, 87.00)ppb vs. 40.00(32.00, 52.00)ppb], eosinophils% (EO%) [10.60(6.75, 13.05) vs. 4.10(1.20, 7.30)], eosinophils (EO) [1.50(1.07, 2.20)×10⁹/L vs. 0.33(0.10, 0.54)×10⁹/L], A.f-specific Immunoglobulin E (sIgE) [10.24(4.09, 22.88)KU/L vs. 1.13(0.53, 3.72) KU/L], and sIgE to total IgE(tIgE) ratio (sIgE/tIgE) [0.0049(0.0027, 0.0100) vs. 0.0008(0.0004, 0.0017)] were higher in ABPA patients, the differences were statistically significant (P<0.001). In all patients, tIgE was positively correlated with EO% (r=0.206, P<0.05) and EO (r=0.302, P<0.001). sIgE/tIgE was negatively correlated with one-second rate (FEV1/FVC%) (r=-0.256, P<0.01). The percentage of predicted forced vital capacity [FVC(%)] was negatively correlated with FeNO (r=-0.184, P<0.05).In the ABPA group, the percentage of predicted peak expiratory flow [PEF(%)] was negatively correlated with FeNO (r=-0.295, P<0.05). In the HDM-sensitized asthma group, FeNO was positively correlated with EO% (r=0.49, P<0.01) and EO (r=0.548, P<0.001).The results of logistic regression analysis showed that FeNO and EO were the influencing factors for the development of ABPA in A.f-sensitized asthma. ROC curve analysis results showed that A.f-sIgE (cut-off, 4.108; AUC=0.749;95%CI, 0.632-0.867), sIgE/tIgE(cut-off, 0.0026;AUC=0.749;95%CI, 0.631-0.868), FeNO(cut-off, 55.5;AUC=0.794; 95%CI, 0.687-0.900), EO% (cut-off, 8.70;AUC=0.806;95%CI, 0.709-0.903) and EO (cut-off, 0.815;AUC=0.865;95%CI, 0.779-0.950) had differential diagnostic value in A.f-sensitized asthma and ABPA.The combination of FeNO, EO and EO% had good diagnostic efficiency in differentiating A.f-sensitized asthma from ABPA, with a sensitivity of 91.4% and a specificity of 84.4%. Conclusion: Compared with patients with A.f-sensitized asthma, patients with ABPA have more severe eosinophil inflammation. The higher the FeNO and EO, the more likely A.f-sensitized asthma will develop into ABPA.sIgE/tIgE may have differential diagnostic value in A.f-sensitized asthma and ABPA.The combination of FeNO, EO and EO% has good diagnostic efficacy in differentiating A.f-sensitized asthma from ABPA.

Among the various drug induced dermatological entities toxic epidermalnecrolysis (TEN) and Stevens-Johnson syndrome (SJS) occupy a primary place in terms of mortality. Toxic epidermal necrolysis also known as Lyell's syndrome was first described by Lyell in 1956. Drugs are by far the most common cause of toxic epidermal necrolysis, in which large sheets of skin are lost from the body surface making redundant the barrier function of the skin, with its resultant complications. Drug-induced toxic epidermal necrolysis are severe adverse cutaneous drug reactions to various precipitating agents that predominantly involve the skin and mucous membranes. Toxic epidermal necrolysis is rare but considered medical emergencies as they are potentially fatal. Drugs are the most common cause accounting for about 65%-80% of the cases. The most common offending agents are sulfonamides, NSAIDs, butazones and hydrantoins. An immune mechanism is implicated in the pathogenesis, but its nature is still unclear. There is a prodormal phase in which there is burning sensation all over the skin and conjunctivae, along with skin tenderness, fever, malaise and arthralgias. Early sites of cutaneous involvement are the presternal region of the trunk and the face, but also the palms and soles, rapidly spread to their maximum extent, the oral mucosa and conjunctiva being affected. Initial lesions are macular, followed by desquamateion, or may be from atypical targets with purpuriccenters that coalesce, from bullae, then slough. The earlier a causative agent is withdrawn the better is the prognosis. Several treatment modalities given in addition to supportive care are reported in the literature, such as systemicsteroids, high-dose intravenous immunoglobulins, ciclosporin, TNF antagonists. Recovery is slow over a period of 14-28 days and relapses are frequent. Mortality is 25%-50% and half the deaths occur due to secondary infection. Here we report a 50-year-old female of drug-induced toxic epidermal necrolysis. She was admitted to the dermatology ward with extensive peeling of skin over the trunk and limbs. She had taken alamotrigine for epilepsy. A week after taking the tablets, the patient developed a severe burning sensation all over the body and followed by a polymorphic erythematous dermatitis and widespread peeling of skin. We treated this patient with high dose corticosteroids, high-dose intravenous immunoglobulins and etanercept, but eventually she died of secondary aspergillus fumigatus infection.

OBJECTIVE: To evaluate the accuracy and diagnostic value of bronchoalveolar lavage fluid galactomannan test (BALF-GM) combined with serum GM test on invasive pulmonary aspergillosis (IPA). METHODS: 190 cases of BALF-GM and 4 787 cases of serum GM specimens suspected of fungal infection in patients admitted to Affiliated Hospital of Jining Medical University from January 2016 to June 2018 were enrolled and analyzed. All patients were classified into clinically confirmed IPA, clinically diagnosed IPA, suspected IPA and excluded IPA according to the classification standard of Expert consensus on diagnosis and treatment of pulmonary mycosis. The coincidence rate of BALF and serum GM test results with clinical diagnosis was analyzed. Receiver operating characteristic (ROC) curve was performed, and the diagnostic value of BALF and serum GM test alone or in combination for IPA was evaluated. Subgroup analysis was performed in patients with normal or abnormal immune function, and the sensitivity and specificity of BALF and serum GM test were compared separately or jointly. RESULTS: The positive rate of BALF-GM was 46.8% (89/190), and 10.4% (497/4 787) on serum GM. Among them, 156 patients were both tested on BALF and serum GM. There were 44 cases with both positive in BALF and serum GM, the coincidence rate of clinical definite was 93.2% (41/44). There were 34 cases with positive BALF-GM and negative GM test in serum, and the coincidence rate of clinical definite was 64.7% (22/34). There were 56 cases positive in serum GM and negative in BALF-GM, and the coincidence rate of clinical definite was 48.2% (27/56). BALF and serum GM tests were both negative in 22 cases, and the coincidence rate of exclusion diagnosis was 90.9% (20/22). ROC curve analysis showed that the diagnostic value of BALF-GM test combined with serum GM test for IPA was better than that of BALF-GM test or serum GM test alone [area under ROC curve (AUC): 0.992 vs. 0.983, 0.976]. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 95.3%, 87.0%, 93.2% and 90.9%, respectively. Subgroup analysis showed that among 89 patients with positive BALF-GM test, 85 cases (95.5%) had normal immune function and 4 cases (4.5%) had unknown condition. Among 497 patients with positive serum GM test, 12 cases (2.4%) had normal immune function, 372 cases (74.9%) had abnormal immune function and 113 cases (22.7%) were uncertain. It was shown by ROC curve analysis that the sensitivity of positive BALF-GM test in diagnosis of IPA in patients with normal immune function was higher than that of positive serum GM test (95.6% vs. 88.9%), while the sensitivity of positive serum GM test in patients with abnormal immune function was higher than that of positive BALF-GM test (91.8% vs. 89.9%). CONCLUSIONS The results of BALF and serum GM tests are in good agreement with clinical diagnosis, and the combined detection of BALF and serum GM is more valuable for IPA diagnosis than single detection, especially for patients with unknown immune function.

Allergic bronchopulmonary mycosis (ABPM) develops mainly in patients with asthma or cystic fibrosis via types I and III hypersensitivity reactions to filamentous fungi. Aspergillus spp., especially Aspergillus fumigatus, is the major causative fungus because of its small conidia, thermophilic hyphae, and ability to secrete serine proteases. The cardinal histological feature of ABPM is allergic (eosinophilic) mucin-harboring hyphae in the bronchi, for which the formation of extracellular DNA trap cell death (ETosis) of eosinophils induced by viable fungi is essential. Clinically, ABPM is characterized by peripheral blood eosinophilia, increased IgE levels in the serum, IgE and IgG antibodies specific for fungi, and characteristic radiographic findings; however, there are substantial differences in the clinical features of this disease between East and South Asian populations. Systemic corticosteroids and/or antifungal drugs effectively control acute diseases, but recurrences are quite common, and development of novel treatments are warranted to avoid adverse effects and emergence of drug-resistance due to prolonged treatment with corticosteroids and/or antifungal drugs.

Aspergilloma of the maxillary sinus is considered rare in immunocompetent patients, but a considerable increase has recently been seen in the incidence of reported cases. Dental procedures involving the antral region are thought to predispose individuals to this form of aspergillosis. Because aspergilloma shares similar clinical features with other sinus pathologies, its diagnosis may be delayed. Thus, an early diagnosis confirmed by a histopathological examination plays a crucial role in the adequate management of aspergilloma. This article provides a concise review of the reported cases of aspergilloma associated with dental procedures and reports 2 new cases of aspergilloma in middle-aged female patients, with a presentation of their cone-beam computed tomographic findings.

PURPOSE: To report a case of abducens nerve palsy and optic perineuritis caused by fungal sphenoidal sinusitis. CASE SUMMARY: A 48-year-old male visited emergency department for retrobulbar pain, decreased vision, and horizontal diplopia for 3 days. He reported that previous medical history was non-specific, however, blood glucose level was 328 mg/dL (70–110). He had experienced severe headache for 7 days. The best corrected visual acuity was 20/20 at right eye and 20/25 at left eye. The pupil of left eye did not have relative afferent pupillary defect. Left mild proptosis was noted. The extraocular examination showed 30 prism diopters left esotropia at primary gaze and −4 abduction limitation of left eye. The left eye showed mild optic disc swelling and inferior field defect by field test. Brain magnetic resonance imaging showed enhancement of sphenoidal sinus, ethmoidal sinus, and around optic nerve at left eye. Three days after antibiotics treatment, the vision of left eye deteriorated to 20/40 and periorbital pain developed. The drainage and biopsy of sphenoidal sinus were performed. The histopathologic examination showed hyphae consistent with aspergillosis. The ocular symptoms were improved with anti-fungal treatment. Follow-up magnetic resonance imaging performed 1 month after treatment showed improvement of lesion at left orbit. Five months after surgery, the visual acuity of left eye was improved to 20/25. The patient showed orthotropia at primary gaze without limitation. CONCLUSIONS: The abducens nerve palsy and optic perineuritis can be caused by fungal sphenoidal sinusitis. The early diagnosis and appropriate treatment can lead to favorable outcome.

BACKGROUND: The complication rate of fungal disease is higher among patients with hematological malignancies. We investigated the clinicobacteriological outcomes of resected pulmonary fungal infections complicating hematological malignancies. METHODS: Between 2001 and 2017, 21 patients with pulmonary fungal infections complicating hematological malignancies underwent resection, and their clinical records and survival were retrospectively reviewed. RESULTS: The median age of the patients was 47 years, and 13 were male. The histological diagnoses were pulmonary aspergillosis (19 cases), mucormycosis (1 case), and cryptococcosis (1 case). The indications for surgery were resistance to antifungal therapy and the necessity of surgery before hematopoietic stem cell transplantation in 13 and 8 cases, respectively. The diagnoses of the hematological malignancies were acute myelogenous leukemia (10 cases), acute lymphocytic leukemia (5 cases), myelodysplastic syndrome (3 cases), and chronic myelogenous leukemia, malignant lymphoma, and extramedullary plasmacytoma (1 case each). The surgical procedures were partial resection (11 cases), segmentectomy (5 cases), lobectomy (4 cases), and cavernostomy (1 case). The size of the lesions was 0.9–8.5 cm. Fourteen cases had cavitation. There were no surgical-related deaths or fungal progression. CONCLUSION: Pulmonary fungal infections are resistant to treatments for hematological malignancies. Since the treatment of the underlying disease is extended and these infections often recur and are exacerbated, surgery should be considered when possible.

Nasal septal infection can result from progression of a fungal infection from the adjacent sinuses. Nasal septal fungal abscesses complicating nasal trauma, surgical procedures, sinus, and dental infections have previously been reported in a small number of cases. Adequate management involves early diagnosis, prompt empiric antifungal therapy, and surgical debridement in order to prevent the development of life-threatening complications. We report a rare case of nasal septum necrosis from Aspergillus infection in a 79-year-old man with diabetes mellitus and chronic renal failure following endoscopic sphenoid sinus surgery due to an isolated sphenoid fungal ball.

Hemicrania continua (HC) is an indomethacin-responsive primary headache. Owing to continuous unilateral headache and clinical rarity, a great attention should be paid during the diagnosis of HC to exclude secondary causes of headache. Various pathologies have been described for HC-like headache. We describe a 64-year old man with invasive sphenoid sinus aspergillosis who presented continuous unilateral headache, trigeminal autonomic symptoms and response to oral indomethacin 225 mg/day. He was treated with intranasal ethmoidectomy and antifungal agent, and his headache has greatly improved.
