Can BCG treatments cause tuberculosis?
Because BCG is a live attenuated organism, it can cause an acute disseminated tuberculosis-like illness if it enters the bloodstream (BCG sepsis), possibly resulting in death. Reports have described BCG vaccine organisms identified on vascular grafts in patients who have died following BCG vaccine sepsis.
How long are you contagious after BCG treatment?
Reproductive Concerns. Men having this treatment can pass on BCG during sex. To protect your partner from coming into contact with BCG, you should not have sex for 48 hours after each treatment. Use a condom if you have sex at other times during the treatment course and for six weeks after treatment has ended.
How toxic is BCG?
BCG has a cumulative effect, so increased toxicity is to be expected during long-term administration. BCG toxicity is primarily a response of the cell-mediated immune system, and transient local or systemic infection appears to be important.
What is the success rate of BCG treatment?
This method of treatment is considered a form of immunotherapy, which is an emerging form of cancer treatment. The success rate for BCG treatment for bladder cancer is about 90%, which is considered the best life-saving rate by any treatment.
Does BCG treatment compromise your immune system?
Bacillus Calmette–Guérin (BCG) vaccination has been reported to decrease susceptibility to respiratory tract infections, an effect proposed to be mediated by the general long-term boosting of innate immune mechanisms, also termed trained immunity.
What is BCG sepsis?
INTRODUCTION: BCG (Bacillus Calmette-Guerin) is a live attenuated strain of Mycobacterium Bovis, used as intravesical immunotherapy for superficial bladder cancers. Complications include cystitis, hepatitis, pneumonitis, arthritis, osteomyelitis, and rarely sepsis.
How long does BCG bacteria live?
Because BCG is a live vaccine, there are some important safety measures to keep in mind that your doctor can explain. BCG can remain in urine for 6 hours after your treatment, so each time you urinate, you should bleach the toilet in your home to neutralize the vaccine.
What happens if BCG gets on your skin?
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
What are long term side effects of BCG?
Commonly reported side effects of bcg include: urinary tract infection, detrusor hyperreflexia of bladder, fever, hematuria, urinary frequency, urinary urgency, vomiting, chills, and malaise. Other side effects include: arthralgia. See below for a comprehensive list of adverse effects.
How often does BCG fail?
Evidence synthesis: Overall, the failure rate in response to BCG is about 40-50%. Most guidelines recommend that patients failing BCG should be offered radical cystectomy (RC).
What happens if BCG fails?
BCG failure usually carries a risk of recurrence but rarely of progression. For low-grade failure, intravesical chemotherapy is a valid option. This scenario is different from that where BCG intravesical therapy is unsuccessful in high-risk T1 disease and/or CIS, where a risk of progression may sometimes reach 50%.
What is considered BCG failure?
BCG refractory is when there is failure to achieve a disease-free state within 6 months after initial BCG, with either maintenance or re-treatment at 3 months because of either persistent or rapidly recurrent disease.

Testing For TB in Bcg-Vaccinated Persons
Treatment For LTBI in Bcg-Vaccinated Persons
- Treatment of LTBI substantially reduces the risk that TB infection will progress to disease. Careful assessment to rule out the possibility of TB disease is necessary before treatment for LTBI is started. Evaluation of TST reactions in persons vaccinated with BCG should be interpreted using the same criteria for those not BCG-vaccinated. Persons in...
