In this study, the clinical and immunogenetical features in a cohort of Chinese patients with BCGosis/BCGitis were investigated. For the patients with abnormal immunological functions, Sanger sequencing was used to identify the involved genes. There were 74 confirmed cases of BCGosis/BCGitis during 2007-2012. Classified by infected tissues and organs, no cases only had local infection, 39 patie...

bcg (bacille calmette–guérin) vaccine is administered worldwide to prevent severe forms of tuberculosis. it is considered to be safe; however, occasional complications are seen. the most serious complication is bcgosis. we report a case of bcgosis with granulomatous hepatitis and acid-fast bacilli in liver and spleen. we treated the patient with antituberculosis drugs without any response to tr...

Major histocompatibility complex (MHC) class II deficiency is a primary immunodeficiency disease characterized by abnormality of MHC class II molecules surface expression on peripheral blood lymphocytes and monocytes. Clinical manifestations include extreme susceptibility to viral, bacterial, and fungal infections but the immunodeficiency is not as severe as SCID (severe combined immunodeficien...

Introduction: In tuberculosis (TB) endemic regions BCG vaccine is administered at birth in an effort to protect against neonatal tuberculous meningitis. However, this live vaccine facilitates overwhelming systemic infections by otherwise innocuous organisms in infants with cellular primary immunodeficiencies . Case Report: Our case is a seven month old infant who developed abscess at BCG vaccin...

BACKGROUND Worldwide, most infants born to mothers infected with human immunodeficiency virus (HIV) receive bacille Calmette-Guérin (BCG) vaccine. Tuberculosis is a major cause of death among infants infected with HIV in sub-Saharan Africa, and it should be prevented. However, BCG may itself cause disease (known as "BCGosis") in these infants. Information regarding the immunogenicity of BCG is ...

Background and Objective: BCG vaccination is used in many countries with a high prevalence of TB to prevent childhood tuberculosis meningitis and miliary disease. Local and systemic sideeffects are associated with BCG vaccine. The most critical reaction is disseminated BCG infection which occurs in mostl...

major histocompatibility complex (mhc) class ii deficiency is a primary immunodeficiency disease characterized by abnormality of mhc class ii molecules surface expression on peripheral blood lymphocytes and monocytes. clinical manifestations include extreme susceptibility to viral, bacterial, and fungal infections but the immunodeficiency is not as severe as scid (severe combined immunodeficien...

background and objective: bcg vaccination is used in many countries with a high prevalence of tb to prevent childhood tuberculosis meningitis and miliary disease. local and systemic sideeffects are associated with bcg vaccine. the most critical reaction is disseminated bcg infection which occurs in mostly immunodeficient patients. materials and methods: we performed 4 autopsies during 2001-2003...

Immunodeficiency and disseminated mycobac-terial infection associated with homozygous nonsense mutation of IKKb To the Editor: Nuclear factor kappa B (NF-kB) signaling is known to be important for host protection against infection. For activation, proteins of the NF-kB transcription factor must be released from constitutive interaction with inhibitory IkB proteins (IkBa, IkBb, and IkBε), which ...

IFN-γ has been used in the treatment of IL-12Rβ1 deficiency patients with disseminated BCG infection (BCGosis), but the optimal dose to reach efficacy is not clear. We used IFN-γ in the treatment of a 2.7-year-old patient with IL-12Rβ1 deficiency and refractory BCG-osis. IFNγ was started at a dose of 50 μg/m² 3 times per week. The dose was upgraded to 100 mcg/m² after 3 months, then to 200 mcg/...
