Pulmonary Blastomycosis: A Rare Cause of Acute Chest Syndrome and Prolonged Fevers in a Pediatric Patient With Sickle Cell Disease.

Blastomyces is a fungus found in the soil of regions of North America including the Mississippi and Ohio River Valleys. It can be inhaled into the lungs and cause pneumonia and disseminated disease. Although blastomycosis is not widely reported in the sickle cell literature, sickle cell patients may be at increased risk of complications from blastomycosis pneumonia due to their immune compromise and risk of developing acute chest syndrome. We describe the case of a 13-year-old female with homozygous sickle cell disease who presented with pneumonia and acute chest syndrome and was found to have pulmonary blastomycosis.

A 34-Year-Old Man With HIV/AIDS and a Cavitary Pulmonary Lesion.

A 34-year-old man presented to a community hospital with fever and fatigue for 3 days and was found to be febrile and tachycardic with a cavitary pulmonary lesion and paratracheal adenopathy on CT imaging. One month before, he had presented to his primary care provider with a palmar rash; he had been diagnosed and treated for syphilis and was also diagnosed with HIV. He had a CD4 count of 106 cells/µL and an HIV viral load of 1,290,000 copies/mL. Pneumocystis prophylaxis with trimethoprim-sulfamethoxazole and antiretroviral treatment with only tenofovir and emtricitabine therapy were started 2 weeks before presentation.

Oral posaconazole and bronchoscopy as a treatment for pulmonary mucormycosis in pediatric acute lymphoblastic leukemia patient: A case report.

RATIONALE: Mucormycosis is a rare fungal infection that typically occurs in immunosuppressed patients following chemotherapy or hematopoietic stem cell transplantation. PATIENT CONCERNS: An 11-year-old child with newly developed acute lymphoblastic leukemia suffered from the paroxysmal left chest pain, fever, and hemoptysis. DIAGNOSES: We made a histopathologic diagnosis aided by bronchoscopy techniques, which indicated invasive fungal hyphae that are characteristic of mucormycosis. INTERVENTIONS: The patient was treated with oral posaconazole and repeated bronchoscopy interventions for 4 months. OUTCOMES: The patient's clinical signs and symptoms and signs were no longer present. The prior lung lesions were also no longer observable using radiologic methods, and a 3-month follow-up with the patient showed no signs of mucormycosis recurrence. Finally, the patient was cured, when the cancer chemotherapy was stopped. Close follow-up for another 2 years showed no evidence of recurrence. LESSONS: Mucormycosis diagnosis is difficult as clinical and imaging findings vary. This case demonstrates that posaconazole monotherapy combined with bronchoscopy interventions may be a safe and effective treatment option for pediatric pulmonary mucormycosis.

Bilateral pleural masses in an immunocompromised patient.

We present a case of persistent pleural masses with mediastinal adenopathy in an immunocompromised patient initially biopsied, diagnosed and treated for Pneumocystis jiroveci pneumonia, ultimately requiring surgical thoracoscopy to diagnose pulmonary histoplasmosis. We discuss the diagnostic approach for pleural masses in immunocompromised patients, the limitations of tissue sampling, interpretation and methodology, and pitfalls of testing in making a pathogen-specific diagnosis.

A 52-Year-Old Man With an 11-Month History of Fever, Cough, Chest Pain, Pleural Effusion, and Left Lung Atelectasis.

CASE PRESENTATION: A 52-year-old man was referred to our hospital for cough, fever, chest pain, and progressive dyspnea. He has worked as a full-time security staff at a community center and was in a normal state of health until 11 months prior to referral when he began experiencing cough, expectoration, a high-grade fever (up to 39.7°C), chills, and left chest pain. He visited the local hospital several times with suspected lung cancer. Bronchoscopy showed chronic inflammatory changes in his bronchi. He was given a course of antibiotics, but his fever had not subsided. The patient had visited a bamboo rat farm and consumed bamboo rat meat one year previously. He had never smoked.

A Previously Healthy 37-Year-Old Man With Acute Hypoxic Respiratory Failure and Fevers.

CASE PRESENTATION: A previously healthy 37-year-old man initially presented to a hospital near his home with persistent cough after failing outpatient azithromycin for empiric treatment of pneumonia. He was newly employed as a bulldozer operator burying trash in a landfill in Virginia, which he continued throughout his illness. He owned two healthy dogs, had never traveled outside the state, and denied a history of cigarette smoking, alcohol, and substance use. His WBC count was 13.4 × 109/L (11% eosinophils). CT scan of the chest showed ground glass opacities. Subsequent bronchoscopy with BAL of the right middle lobe showed eosinophilic predominance (46%); transbronchial biopsy of right lower lobe was performed. Infectious and autoimmune work up that was negative included blood, urine, and BAL cultures, BAL Pneumocystis pneumonia direct immunofluorescence assay, urine legionella antigen, serum HIV antibody, antinuclear antibodies, anti-neutrophil cytoplasmic antibodies, and angiotensin converting enzyme. After improvement in hypoxia with inpatient corticosteroid therapy, he was discharged home with a two week course of prednisone for a presumptive diagnosis of acute eosinophilic pneumonia. He subsequently experienced worsening fever and difficulty breathing; six weeks after his symptoms began, he was admitted to our hospital.

Conidiobolus pachyzygosporus invasive pulmonary infection in a patient with acute myeloid leukemia: case report and review of the literature.

BACKGROUND: Conidiobolus spp. (mainly C. coronatus) are the causal agents of rhino-facial conidiobolomycosis, a limited soft tissue infection, which is essentially observed in immunocompetent individuals from tropical areas. Rare cases of invasive conidiobolomycosis due to C. coronatus or other species (C.incongruus, C.lamprauges) have been reported in immunocompromised patients. We report here the first case of invasive pulmonary fungal infection due to Conidiobolus pachyzygosporus in a Swiss patient with onco-haematologic malignancy. CASE PRESENTATION: A 71 year-old female was admitted in a Swiss hospital for induction chemotherapy of acute myeloid leukemia. A chest CT performed during the neutropenic phase identified three well-circumscribed lung lesions consistent with invasive fungal infection, along with a positive 1,3-beta-d-glucan assay in serum. A transbronchial biopsy of the lung lesions revealed large occasionally septate hyphae. A Conidiobolus spp. was detected by direct 18S rDNA in the tissue biopsy and subsequently identified at species level as C. pachyzygosporus by 28S rDNA sequencing. The infection was cured after isavuconazole therapy, recovery of the immune system and surgical resection of lung lesions. CONCLUSIONS: This is the first description of C. pachyzygosporus as human pathogen and second case report of invasive conidiobolomycosis from a European country.

Clinicopathologic characteristics and outcomes of lupus nephritis with positive antineutrophil cytoplasmic antibody.

Aims: The aim was to determine whether anti-neutrophil cytoplasmic antibody (ANCA)-positive serology in patients with lupus nephritis (LN) is associated with different clinicopathologic features and outcomes.Methods: In our retrospective analysis, 283 patients were enrolled between 2013 and 2018. Thirty-six patients were ANCA-positive, and this group was compared with the remaining 247 patients who were confirmed as ANCA-negative at the time of biopsy.Results: ANCA-positive LN patients exhibited higher anti-dsDNA antibody titers and serum creatinine levels and lower serum hemoglobin concentrations than ANCA-negative LN patients. On pathological evaluation, segmental endocapillary hypercellularity observed by light microscopy was significantly more common in the ANCA-positive group. This feature was not significantly different in the treatment group, but the response to treatment was significantly different, as was remission (76.1% vs 69.4%, p < 0.001), between the ANCA-negative and ANCA-positive groups. During follow-up, the times to renal replacement therapy (RRT) and death were significantly different between the two unmatched groups (chi-square test, p = 0.041). Multivariate Cox analysis revealed that neurological disorders, ANCA positivity, and the chronicity index (CI) remained independent risk factors for patient survival. Pulmonary infection was the main cause of death and was most often due to fungal infection.Conclusion: ANCA-positive LN patients typically exhibited higher anti-dsDNA antibody titers, lower serum hemoglobin concentrations and worse renal function than ANCA-negative LN patients. Fungal infection was the main cause of death. We observed that ANCA positivity was an independent risk factor for patient survival.

Chinese Expert Recommendation for Diagnosis and Treatment of Massive Hemoptysis.

Massive hemoptysis is one of emergency and critical diseases of the respiratory system. The definition of massive hemoptysis has always been different in the literature, which often depends on the quantitative estimation of the amount of hemoptysis, such as the amount of hemoptysis being in the range of 300-600 mL within 24 h, or hemoptysis more than 3 times within 1 week. Each amount of hemoptysis that is greater than 100 mL can be considered as massive hemoptysis, but the amount of hemoptysis is difficult to accurately estimate. Therefore, massive hemoptysis can be defined as any life-threatening hemoptysis and any hemoptysis that may cause airway obstruction and asphyxia. Massive hemoptysis accounts for approximately 5% of all hemoptysis cases and usually indicates the presence of a potentially severe respiratory or systemic disease. The mortality rate of massive hemoptysis is about 6.5-38%. The cause of death is generally shock caused by airway obstruction or excessive bleeding, and asphyxia is the main cause of death. At present, due to insufficient understanding of massive hemoptysis, there are limited technical means in the etiological diagnosis and untimely or improper treatment, resulting in high mortality of massive hemoptysis. Therefore, the diagnosis and treatment of massive hemoptysis needs to be standardized.

Characteristics and risk factors for mortality of invasive non-Aspergillus mould infections in patients with haematologic diseases: A single-centre 7-year cohort study.

Since mould-active azole prophylaxis has become a standard approach for patients with high-risk haematologic diseases, the epidemiology of invasive fungal infections (IFIs) has shifted towards non-Aspergillus moulds. It was aimed to identify the epidemiology and characteristics of non-Aspergillus invasive mould infections (NAIMIs). Proven/probable NAIMIs developed in patients with haematologic diseases were reviewed from January 2011 to August 2018 at Catholic Hematology hospital, Seoul, Korea. There were 689 patients with proven/probable invasive mould infections; of them, 46 (47 isolates) were diagnosed with NAIMIs. Fungi of the Mucorales order (n = 27, 57.4%) were the most common causative fungi, followed by Fusarium (n = 9, 19.1%). Thirty-four patients (73.9%) had neutropenia upon diagnosis of NAIMIs, and 13 (28.3%) were allogeneic stem cell transplantation recipients. The most common site of NAIMIs was the lung (n = 27, 58.7%), followed by disseminated infections (n = 8, 17.4%). There were 23.9% (n = 11) breakthrough IFIs, and 73.9% (n = 34) had co-existing bacterial or viral infections. The overall mortality at 6 and 12 weeks was 30.4% and 39.1%, respectively. Breakthrough IFIs (adjusted hazards ratio [aHR] = 1.99, 95% CI: 1.3-4.41, P = .031) and surgical treatment (aHR = 0.09, 95% CI: 0.02-0.45, P = .003) were independently associated with 6-week overall mortality. NAIMIs were not rare and occur as a complex form of infection often accompanied by breakthrough/mixed/concurrent IFIs and bacterial or viral infections. More active diagnostic efforts for NAIMIs are needed.

Surgical resection for persistent localized pulmonary fungal infection prior to allogeneic hematopoietic stem cell transplantation: Analysis of six cases.

OBJECTIVE: Although invasive fungal disease (IFD) is an important complication in allogeneic hematopoietic stem cell transplantation (HSCT), the clinical significance of surgery, including the role of surgical resection for persistent pulmonary fungal disease prior to allogeneic HSCT in the current era with a variety of available antifungal agents, is controversial. We investigated the role of surgical resection. METHODS: We retrospectively investigated six patients who underwent surgical resection of suspected pulmonary fungal disease prior to allogeneic HSCT between April 2007 and June 2016 at our medical center. RESULTS: We present six patients who underwent surgical resection of suspected pulmonary fungal disease prior to allogeneic HSCT. In our case series, three of four patients who were given a presurgical diagnosis of possible IFD were given a proven diagnosis after surgery, including two cases of invasive aspergillosis (IA) and one case of mucormycosis. All surgeries were performed by video-assisted thoracic surgery (VATS) for lobectomy without major complications. Recurrence of IFD was not observed after allogeneic HSCT in any of the six patients. CONCLUSION: Our experience indicated that surgical resection of persistent localized pulmonary lesions of IFD before allogeneic HSCT was helpful for obtaining a definitive diagnosis and might be useful for reducing recurrence after HSCT.

Concomitant lung adenocarcinoma and pulmonary cryptococcosis confirmed by pathologic examinations.

To describe the characteristics of concomitant lung cancer and pulmonary cryptococcosis (PC) cases.A total of 8 patients with lung cancer and coexisting PC, who were admitted to Fuzhou Pulmonary Hospital of Fujian from 1st January 2009 to 31st December 2015 and whose diagnoses were confirmed by pathological examinations, were studied.One patient had a history of diabetes mellitus and 1 had a history of treated with surgery. The lesions in 7 cases manifested as nodular shadows; only 1 case showed the lesion of the 2 diseases mergedmixed together, and it manifested as a large flake-like infiltrated shadow in the same lobe. The histological type in all of the patients was lung adenocarcinoma. Lung cancer stage was advanced (III-IV) in 25.0% of the cases. The 5 patients who received surgery and drug treatment are presently healthy following resection. Recurrence and metastasis of lung cancer following surgery occurred in 2 patients in whom the tumor was controlled again after anti-tumor treatment. One patient with advanced lung cancer and PC was treated with antifungal therapy in combination with antineoplastic chemotherapy, but she failed to improve and died 10 months after symptom onset during the follow-up period.PC coexisting with pulmonary carcinoma is rare. PC can manifest as pulmonary nodules and mimic malignant lesions, so it must be considered during a differential diagnosis of pulmonary nodules, especially in immunosuppressed patients.

Isolated Pulmonary Mucormycosis in an immunocompetent patient.

Mucormycosis is a life-threatening fungal infection that occurs mainly in immunocompromised patients. Its occurrence isolated in the lung rare and carries a high mortality risk if untreated. We report the case of a 76-year old male immunocompetent patient, under treatment for pulmonary tuberculosis, admitted to the emergency department with hemoptysis. Bronchoscopy was performed and active bleeding from the middle lobe bronchus was found. Chest CT scan identified a solitary cavitary lesion in the middle lobe. The patient was proposed for urgent open middle lobectomy. Postoperative period was uneventful. Pulmonary mucormycosis was confirmed and adjuvant therapy with Amphotericin B was performed for 30 days. Despite its rarity, mucormycosis prevalence is expected to raise together with increasing number of immunocompromised patients. A high level of suspicion is recommended as early diagnosis can be determinant.

Pulmonary scedosporiosis in a patient with acute hematopoietic failure: Diagnosis aided by next-generation sequencing.

We report the first case of pulmonary scedosporiosis detected by next-generation sequencing (NGS) from bronchoalveolar lavage fluid (BALF) in a 67-year-old male with bronchiectasis and hematopoietic failure. Scedosporium apiospermum is a ubiquitous organism present in the environment with intrinsic resistance to many antifungal agents. The patient developed respiratory failure, pulmonary consolidation, and septic shock shortly thereafter, and responded poorly to antifungal therapy. This case highlights the combined application of NGS and traditional fungal culture in the clinical diagnosis of pulmonary invasive fungal disease. NGS is proposed as an important adjunctive diagnostic approach for uncommon pathogens.

Disseminated histoplasmosis from a calcified lung nodule after long-term corticosteroid therapy in an elderly Japanese patient: A case report.

RATIONALE: Histoplasmosis occurs most commonly in Northern and Central America and Southeast Asia. Increased international travel in Japan has led to a few annual reports of imported histoplasmosis. Healed sites of histoplasmosis lung infection may remain as nodules and are often accompanied by calcification. Previous studies in endemic areas supported the hypothesis that new infection/reinfection, rather than reactivation, is the main etiology of symptomatic histoplasmosis. No previous reports have presented clinical evidence of reactivation. PATIENT CONCERNS: An 83-year-old Japanese man was hospitalized with general fatigue and high fever. He had been treated with prednisolone at 13 mg/d for 7 years because of an eczematous skin disease. He had a history of travel to Los Angeles, Egypt, and Malaysia 10 to 15 years prior to admission. Five years earlier, computed tomography (CT) identified a solitary calcified nodule in the left lingual lung segment. The nodule size remained unchanged throughout a 5-year observation period. Upon admission, his respiratory condition remained stable while breathing room air. CT revealed small, randomly distributed nodular shadows in the bilateral lungs, in addition to the solitary nodule. DIAGNOSIS: Disseminated histoplasmosis, based on fungal staining and cultures of autopsy specimens. INTERVENTIONS: The patient's fever continued despite several days of treatment with meropenem, minocycline, and micafungin. Although he refused bone marrow aspiration, isoniazid, rifampicin, ethambutol, and prednisolone were administered for a tentative diagnosis of miliary tuberculosis. OUTCOMES: His fever persisted, and a laboratory examination indicated severe thrombocytopenia with disseminated intravascular coagulation. He died on day 43 postadmission. During autopsy, the fungal burden was noted to be higher in the calcified nodule than in the disseminated nodules of the lung, suggesting a pathogenesis involving endogenous reactivation of the nodule and subsequent hematogenous and lymphatic spread. LESSONS: Physicians should consider histoplasmosis in patients with calcified nodules because the infection may reactivate during long-term corticosteroid therapy.

Fungal pneumonia manifesting as cavitary lesions in a critically ill elderly patient.

Elderly patients with fungal pneumonia experience higher mortality and are more likely to be misdiagnosed. The diagnosis and treatment of fungal pneumonia in elderly patients is challenging. We herein present a clinical case of pulmonary fungal infection (PFI) manifesting as cavitary lesions in an 85-year-old male with multiple organ failure. Broad-spectrum antibiotics showed unsatisfactory result in this case. Computed tomography (CT) of the chest showed multiple pulmonary cavities with gas-fluid levels in the right upper and middle lobe, and patchy blurred shadows in the lower lobe. The diagnosis of fungal pneumonia was made after ruling out other causes of fever. The patient showed good response to anti-fungal treatment. Physicians must consider the possibility of fungal pneumonia in elderly patients who do not respond to antibiotic treatment after exclusion of immune response, tumor, tuberculosis, and other systemic infections.
