Proper induction of Th1 immunity is required for effective immunotherapy of bladder cancer with the bacillus Calmette-Guérin (BCG). Interleukin-10 (IL-10) downregulates the Th1 immune response and is associated with BCG therapy failure. We evaluated BCG plus IL-10 blocking antibodies and found that this combination therapy induces enhanced Th1 immune responses and anti-bladder cancer immunity i...

Optimal management of high-risk non-muscle-invasive bladder cancer during the current bacillus Calmette-Guérin (BCG) shortage is challenging. Although no evidence-based guidelines exist for this specific situation, current management options can be adapted for when BCG supplies are limited or when BCG is unavailable.

Intravesical instillation of Bacillus Calmette-Guérin (BCG) is used as an adjuvant treatment bladder cancer. Systemic BCG infection occurs in less than 1% cases, and pulmonary involvement even rarer (0.3% – 0.7%), with a favourable prognosis. A 78-year-old male developed miliary tuberculosis (TB) secondary to intravesical subsequent coronavirus disease 2019 (COVID-19) superinfection that led pa...

Aim: This review is written to describe the role of immunotherapy in cancer treatment. Annually, 13,000 deaths result from bladder cancer. Since the first report of intravesical use of BCG in 1976, investigators try to understand the working mechanism of BCG as an antitumour modality. Arbitrarily, BCG therapy consists of a single course of six weekly intravesical instillations. Bacillus Calmett...

Interleukin-15 (IL-15) transgenic mice which had been inoculated with Mycobacterium bovis bacillus Calmette-Guérin (BCG) 24 weeks previously showed resistance against airborne infection with Mycobacterium tuberculosis H37Rv accompanied by an increased CD8(+)-Tc1-cell response. IL-15 may be used as an immune adjuvant given with BCG vaccination to enhance its biologic efficacy.

When it comes to the treatment of patients with non-muscle-invasive bladder cancer (NMIBC) intravesical bacillus Calmette-Guérin (BCG), two questions must be considered: 1) what dose give, and 2) for how long? The issue optimal duration has been subject several randomized trials is especially pertinent in context a global BCG shortage. Despite this, there appears uncertainty as whether or may c...

BCG therapy is used as a treatment in bladder cancer. Intravesical administration of Bacillus Calmette-Guérin is used as a treatment method in superficial bladder cancer. While it is commonly effective, some serious side effects may occur. We hereby report a 65-year-old man who developed granulomatous hepatitis as a complication following BCG therapy. He was treated successfully with antituberc...

Intravesical bacillus Calmette Guérin (BCG) instillation has been used as immunotherapy for early stage bladder cancer for >40 years. Complications from this therapy are rare but may result in a spectrum of infectious sequelae. Here we describe the case of an elderly man who presented with a pleural effusion and subcutaneous nodule several years after treatment with BCG.

A live, attenuated form of Mycobacterium bovis, bacillus Calmette-Guérin (BCG), is commonly used as intravesical immunotherapy for non-invasive urothelial bladder carcinoma. While complications are rare, dissemination can occur. A case of mycotic aortic aneurysm following BCG administration with recovery of Mycobacterium bovis in culture is reported. A review of the published experience with th...

We present a case of acute prostatitis with abscess. The patient had undergone intravesical bacillus Calmette-Guérin (BCG) immunotherapy for bladder cancer. A prostate biopsy demonstrated tuberculous prostatitis with abscess. This case illustrates that when bladder cancer is treated with BCG, a tuberculous prostate abscess can develop.
