We report an 81-year-old male who developed severe interstitial pneumonitis on maintenance intravesical Bacillus Calmette-Guerin (BCG) for in-situ carcinoma of the bladder. The patient was treated with steroids and anti-tuberculin therapy with complete response. While there is no established standard of care for the treatment of interstitial pneumonitis, recent reports describe success with com...

Recent insights into anti-tumor immunotherapy have led to a wave of clinical trials involving immunotherapy for lung cancer.Vaccines have evolved from nonspecific immune stimulants, like Bacillus Calmette-Guerin (BCG), to much more specific and potent strategies, some of which generate active immune responses against tumor-associated antigens. Understanding the mechanisms of anti-tumor immunity...

Intravesical instillation of Bacillus Calmette-Guerin (BCG) is a treatment to prevent recurrence of superficial urothelial bladder carcinoma. Complications after bladder instillation of BCG have been reported including locally invasive and systemic infections due to dissemination of Mycobacterium bovis from the bladder. We present an uncommon case and literature review of prosthetic joint infec...

Repeated intradermal vaccination with mixtures of cultured cells and living Bacillus Calmette-Guérin organisms induced delayed hypersensitivity to antigens of the target cells in three-fourths of the patients studied. This was associated with relatively little antibody production. The specific sensitization was accompanied by persistent general increase of cellular immune reactivity, in most c...

A variety of heat-killed bacteria were tested for their capacity to induce regressions of established line 10 hepatocarcinomas in syngeneic guinea pigs. Multiple intralesional injections of heat-killed Escherichia coli, Streptococcus mutans, Listeria monocytogenes, and Propionibacterium acnes resulted in complete regression of the tumor in a majority of guinea pigs. Repeated injections of heat-...

Intravesical Bacillus Calmette-Guérin (BCG) has long been the gold standard treatment of nonmuscle invasive bladder cancer. Recently, there has been an emergence of novel immunotherapeutic agents, which have shown promise in the treatment of urothelial cell carcinoma. These agents aim to augment, modify, or enhance the immune response. Such strategies include recombinant BCG, monoclonal antibod...

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...

Intravesical instillation of Bacillus Calmette-Guérin is the elective treatment for transitional cell and in situ bladder carcinoma. Severe complications occur very seldom, but must be known and promptly recognized. We describe the case of a 48-year-old man, treated with chemo-immunotherapy ten years before for a follicular lymphoma, who developed a systemic granulomatous reaction after his twe...

Bacillus Calmette-Guerin (BCG),4 an attenuated strain of Mycobacterium bovis, was developed as a vaccine against human tuberculosis by Calmette and Guerin at the Pasteur Institute in 1908. BCG has recently regained the spotlight in completely different roles, that of an immunological adjuvant and "'antitumor" agent. Investigations with this agent in the immunotherapy of cancer have met with var...
