: We herein report the first documented case of acute hypersensitivity pneumonitis in which Candida guilliermondii was the possible causative organism. A young Japanese woman presented to our hospital with relapsing respiratory symptoms accompanied by high fever. A detailed interview revealed that the onset of the symptoms occurred shortly after using a humidifier in her home. Her symptoms showed spontaneous improvement soon after admission, and an examination of her bronchoalveolar lavage fluid revealed the specific infiltration of inflammatory cells, which predominantly consisted of lymphocytes. Precipitin testing showed a positive reaction to C. guilliermondii, which was isolated from the home humidifier. Repeated history taking is essential for diagnosing occult respiratory disorders.

The aim of this document was to provide a critical review of the current knowledge on hypersensitivity pneumonitis caused by the occupational environment and to propose practical guidance for the diagnosis and management of this condition. Occupational hypersensitivity pneumonitis (OHP) is an immunologic lung disease resulting from lymphocytic and frequently granulomatous inflammation of the peripheral airways, alveoli, and surrounding interstitial tissue which develops as the result of a non-Ig...

Rationale: Hypersensitivity pneumonitis (HP) is an immunologically mediated lung disease induced by the inhalation of any of a wide variety of antigens. For example, bird-related HP (BRHP) results from the inhalation of avian antigens. The clinical features of chronic HP, including imaging and histological findings, are similar to those of idiopathic pulmonary fibrosis. Despite its status as the “gold standard,” the inhalation provocation test (IPT) is rarely performed, because the methods and t...

Allergic diseases are considered the epidemics of the twentieth century estimated to affect more than 30% of the population in industrialized countries with a still increasing incidence. During the past two decades, the application of molecular biology allowed cloning, production and characterization of hundreds of recombinant allergens. In turn, knowledge about molecular, chemical and biologically relevant allergens contributed to increase our understanding of the mechanisms underlying IgE-medi...

Summary Candida guilliermondii is an uncommon isolate throughout most of the world, the behaviour of which as an environmental fungus, a human saprophyte and an agent of serious infections has been emphasised over the years. Notably, illnesses caused by this pathogen mostly involve compromised cancer hosts and commonly lead patients to unfavourable outcomes. It is of concern that the yeast may acquire or inherently express reduced in vitro sensitivity to all antifungal classes, although widespre...

Abstract Hypersensitivity pneumonitis (HP) is a lung disease caused by heavy and recurrent inhalation of antigens. We describe the case of a patient with HP caused by domestic exposure to Candida spp. The diagnosis was made by taking into consideration the clinical presentation, exposure history, radiological findings, bronchoalveolar lavage, lung function and the immuno-allergy study. The diagnosis was definitively confirmed by performing a specific bronchial provocation test. It has been shown...

Resumen La neumonitis por hipersensibilidad (NH) es una enfermedad pulmonar debida a la exposicion a diferentes antigenos por via inhalada de forma intensa y recurrente. Describimos el caso de un paciente con NH por exposicion domestica a Candida spp. Para llegar al diagnostico se consideraron la presentacion clinica, el antecedente de exposicion, los hallazgos radiologicos, el lavado broncoalveolar, la funcion pulmonar y el estudio inmunoalergologico, siendo confirmado de forma definitiva tras ...

Abstract:Bird fancier's lung (BFL) is one of the most common types of hypersensitivity pneumonitis. Nevertheless, the criteria for diagnosing this condition are not standardized. The current study is an in-depth investigation into the clinical characteristics of BFL in the largest series examined fo

Background: Extrinsic allergic alveolitis (EAA) is an important clinical entity, but its incidence and significance in the general population are uncertain. Aim: To estimate the incidence of EAA, and resulting mortality, in the UK. Design: General-population-based cohort study in a UK primary care database (THIN). Methods: THIN patients with an incident diagnosis of EAA were compared with a general population cohort whose members were 4:1 matched with EAA patients by age, sex and GP practice. Fo...

Hypersensitivity pneumonitis is an immune-mediated inflammatory lung disease characterised by the inhalation of environmental antigens leading to acute and chronic lung injury. Along with suggestive clinical and radiological findings, history and timing of suspected antigen exposure are important elements for diagnostic confidence. Unfortunately, many diagnoses remain tentative and based on vague and imprecise environmental or material exposure histories. To date, there has not been a comprehens...

Activation of blood coagulation pathways as a component of an allergic response has been studied in animal models. In patients with allergic diseases, clot qualities have been noted to be different in terms of denser fibrin clot with reduced plasmin-mediated clot lysis. Correlation between occupational hypersensitivity pneumonitis (HP) with thromboembolic events is scarce in the general patient population. We present a case of a 52-year-old man with recurrent venous thromboembolism with HP secon...
