a case of summer-type hypersensitivity pneumonitis accompanied by the syndrome of inappropriate secretion of antidiuretic hormone.

[A CASE OF SUMMER-TYPE HYPERSENSITIVITY PNEUMONITIS ACCOMPANIED BY THE SYNDROME OF INAPPROPRIATE SECRETION OF ANTIDIURETIC HORMONE]. Arerugi. 2018;67(1):62-66 Authors: Abe Y, Kawasaki T, Shimaya K, Ishikawa T, Kata Y, Okayasu K, Unoura K, Nakamura Y Abstract A 47-year old man presented to our hospital with a 6-month history of malaise, cough and dyspnea on exertion. Laboratory testing revealed the severe hyponatremia. A chest X-ray showed bilateral diffuse micronodules. Anti-Trichosporon asahii antibody and environmental provocation test were positive. Bronchoalveolar lavage fluid showed lymphocytosis and low CD4/8 ratio. The specimens obtained by transbronchial lung biopsy revealed alveolitis. Based on these findings, the patient was diagnosed as having summer-type hypersensitivity pneumonitis (SHP). The patient was treated with antigen avoidance and oral corticosteroid. The hyponatremia caused by syndrome of inappropriate secretion of antidiuretic hormone (SIADH) was treated with normal saline and water restriction. Serum sodium level was improved with treatment of SHP, which suggested the relevance between SHP and SIADH. PMID: 29459527 [PubMed - in process]

RARITAN, NJ, February 10, 2020 – The Janssen Pharmaceutical Companies of Johnson &Johnson announced today the submission of a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) seeking approval of DARZALEX® (daratumumab) in combination with Kyprolis® (carfilzomib) and dexamethasone (DKd) for relapsed/refractory multiple myeloma. The sBLA is supported by results from the Phase 3 CANDOR study, which compared treatment with DKd to carfilzomib and dexamethasone (Kd) in patients with multiple myeloma who relapsed after one to three prior lines of therapy. “Wh...

Abstract Pneumocystis jiroveci remains an important fungal pathogen in a broad range of immunocompromised hosts. The natural reservoir of infection remains unknown. Pneumocystis jiroveci Pneumonia (PJP) develops via airborne transmission or reactivation of inadequately treated infection. Nosocomial clusters of infection have been described among immunocompromised hosts. Subclinical infection or colonization may occur. Pneumocystis pneumonia occurs most often within 6 months of organ transplantation and with intensified or prolonged immunosuppression, notably with corticosteroids. Infection is also common during ne...

This report describes a patient who was diagnosed with ABPA and soon developed PTE. Patient concerns: A 64-year-old man was diagnosed with ABPA in hospital for recurrent fever with cough. Two months later, the patient was readmitted to the hospital because of PTE. Diagnoses: ABPA was diagnosed during the first hospitalization, and laboratory tests showed an increase in serum IgE and Aspergillus fumigatus-specific IgG. Sputum culture suggested A. fumigatus and high-resolution computed tomography (HRCT) showed inflammation of both lungs and central bronchiectasis. During the second hospitalization, the patient's chest ...
