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...

the calmette-güerin vaccine (bcg) is administered to all the newborns in iran in order to prevent tuberculosis. complications of this vaccine are uncommon. we report disseminated bcg disease in 17 patients less than 10 years old. this is a retrospective study of total of 17 cases who were admitted in children medical center hospital with systemic syndrome compatible with mycobacterium disease w...

Complete interferon-gamma receptor 1 (IFNgammaR1) deficiency has been identified previously as a cause of fatal bacillus Calmette-Guérin (BCG) infection with lepromatoid granulomas, and of disseminated nontuberculous mycobacterial (NTM) infection in children who had not been inoculated with BCG. We report here a kindred with partial IFNgammaR1 deficiency: one child afflicted by disseminated BCG...

INTRODUCTION In Canada, bacille Calmette-Guerin (BCG) vaccine is now primarily given to First Nations and Inuit (FNI) neonates living in tuberculosis (TB) endemic areas. With declining TB rates, attention has shifted from the protective effects of BCG to reports of serious vaccine-associated adverse events (VAAE). METHODS Surveillance data were reviewed to assess TB burden and trends, BCG cov...

OBJECTIVE To determine the population-based incidence of disseminated bacille Calmette-Guérin (BCG) disease in HIV-infected infants (aged <or= 1 year) in a setting with a high burden of tuberculosis and HIV infection coupled with a well-functioning programme for the prevention of HIV infection in infants. METHODS The numerator, or number of new cases of disseminated BCG disease, was derived f...

The attenuated strain of Mycobacterium bovis bacille Calmette-Guérin (BCG) is the most widely used vaccine in the world. In most children, inoculation of live BCG vaccine is harmless although it occasionally leads to a benign regional adenitis. In rare cases, however, vaccination causes disseminated BCG infection, which may be lethal. Impaired immunity of the host is generally thought to be the...

In high-burden countries, Mycobacterium bovis Bacillus Calmette-Guérin (BCG) vaccine is administered in newborn to prevent severe Mycobacterium tuberculosis infection. Because life-threatening disseminated BCG disease may occur in children with primary immunodeficiency, vaccination strategy against tuberculosis should be redefined in non-high-burden countries. We report the case of a patient wi...

Disseminated mycobacterial infection after bacillus Calmette-Guerin (BCG) vaccination is a very rare disorder, occurring mostly in patients with immunologic deficiency. We report a case of disseminated BCG infection in a 16-month-old girl with severe combined immunodeficiency. Plain radiographs showed multiple osteolytic lesions in the femora, tibiae, humerus, and phalanges. Abdominal sonograph...

BACKGROUND Intravesical instillation of Bacillus Calmette-Guérin (BCG) remains a first-line treatment for superficial transitional cell carcinoma of the bladder. Although its use is relatively safe, severe complications such as granulomatous hepatitis, osteomyelitis, pneumonitis, and sepsis occur in few patients. Complications of intravesical instillation of BCG can be local or systemic, with e...
