Intra-vesical instillations with bacillus Calmette-Guerin (BCG) are the established adjuvant therapy for superficial bladder cancer. Although generally safe and well tolerated, they may cause a range of different, local, and systemic complications. We present a patient treated with BCG instillations for three years, who was admitted to our hospital due to fever, hemoptysis, pleuritic chest pain and progressive dyspnea. Chest computed tomography (CT) showed massive bilateral ground glass opacities, partly consolidated, localized in the middle and lower parts of the lungs, bronchial walls thickening, and bilateral hilar lymphadenopathy. PCR tests for SARS-CoV-2 as well as sputum, blood, and urine for general bacteriology—were negative. Initial empiric antibiotic therapy was ineffective and respiratory failure progressed. After a few weeks, a culture of M. tuberculosis complex was obtained from the patient’s specimens; the cultured strain was identified as Mycobacterium bovis BCG. Anti-tuberculous treatment with rifampin (RMP), isoniazid (INH) and ethambutol (EMB) was implemented together with systemic corticosteroids, resulting in the quick improvement of the patient’s clinical condition. Due to hepatotoxicity and finally reported resistance of the BCG strain to INH, levofloxacin was used instead of INH with good tolerance. Follow-up CT scans showed partial resolution of the pulmonary infiltrates. BCG infection in the lungs must be taken into consideration in every patient treated with intra-vesical BCG instillations and symptoms of protracted infection. Full article

Introduction: Immunodeficient children are at a high risk of disseminated Bacillus Calmette-Guérin [BCG] infection. We assessed the literature on clinical manifestations of BCGosis in children with specific primary immunodeficiencies. Material and methods: We conducted a systematic review of clinical practice articles by searching Medline, PubMed, Embase, Scopus, Web of Science and Google Scholar from their inception to date. Results: Thirty-seven articles were included regarding BCG vaccination and its dissemination in children with primary immunodeficiencies. Articles on dissemination after intravesicular BCG were excluded from the study. Conclusions: Since disseminated BCG vaccination may be the first manifestation of a primary immunodeficiency disease, a comprehensive search for immunological defects in children developing these problems after BCG vaccination seems rational.
