Abstract
Deep brain stimulation (DBS) is an advanced treatment in Parkinson's disease. We describe a 71-year-old patient in whom the DBS got infected with Mycobacterium bovis shortly after intravesical BCG instillations as an adjuvant treatment of bladder cancer. The DBS internal pulse generator and extension wires had to be replaced, and the patient was treated successfully with rifampicin, isoniazid, and ethambutol during three months. This case suggests that physicians need to be aware of the risk of this kind of infection and add a specific Mycobacterial test to the regular cultures.

Abstract
We aimed to assess the proportion of tuberculosis in humans and tuberculosis (TB)-associated abattoir condemnations from the animal sector, as well as determine risk factors of zoonotic tuberculosis at the animal-human interface in Zambia. The study involved 255 presumptive TB patients and 156 cattle carcasses and was conducted from April 2020 to December 2021. Univariable and multivariable logistic regressions were performed for risk factor analysis for zoonotic TB. The overall proportion of bovine tuberculosis in traditional cattle and the proportion of tuberculosis among presumptive TB patients were 39.7% and 10.2%, respectively. Consumption of raw milk (adjusted odds ratio (AOR)=2.72, 95% confidence interval (CI): 1.73-4.28) and history of previous contact with a TB patient (AOR=1.86, 95% CI: 1.17-2.95) were risk factors for zoonotic TB at the animal-human interface of Zambia. Therefore, community campaigns and sensitization on zoonotic TB transmission are recommended.

Abstract
OBJECTIVE Children are an important demographic group for understanding overall tuberculosis epidemiology, and monitoring of childhood tuberculosis is essential for appropriate prevention. The present study sought to characterize the spatial distribution of childhood tuberculosis notification rates in continental Portugal; identify high-risk areas; and evaluate the association between childhood tuberculosis notification rates and socioeconomic deprivation. METHODS Using hierarchical Bayesian spatial models, we analyzed the geographic distribution of pediatric tuberculosis notification rates across 278 municipalities between 2016 and 2020 and determined high-risk and low-risk areas. We used the Portuguese version of the European Deprivation Index to estimate the association between childhood tuberculosis and area-level socioeconomic deprivation. RESULTS Notification rates ranged from 1.8 to 13.15 per 100,000 children under 5 years of age. We identified seven high-risk areas, the relative risk of which was significantly above the study area average. All seven high-risk areas were located in the metropolitan area of Porto or Lisbon. There was a significant relationship between socioeconomic deprivation and pediatric tuberculosis notification rates (relative risk = 1.16; Bayesian credible interval, 1.05-1.29). CONCLUSIONS Identified high-risk and socioeconomically deprived areas should constitute target areas for tuberculosis control, and these data should be integrated with other risk factors to define more precise criteria for BCG vaccination.

Abstract
Intravesical instillation of bacillus Calmette-Guérin (BCG) is the adjuvant therapy for superficial urothelial carcinoma of the bladder with the lowest recurrence rates and is well tolerated with minor and self-limiting adverse effects. Serious complications, such as systemic BCG infection, are uncommon as the diagnosis is difficult and, in the majority of cases, Mycobacterium bovis cannot be isolated. We describe a case of a man who presented with prolonged fever associated with polyuria, dysuria, anorexia, and significant weight loss, refractory to several courses of appropriate antibiotic therapy. After an exhaustive investigation, the underlying diagnosis of systemic BCG infection with renal involvement was considered. Antituberculosis treatment resulted in a marked clinical and radiological recovery, supporting this diagnosis.

Abstract
INTRODUCTION Bacillus Calmette Guerin (BCG) vaccine, which is administered to all newborns in Tunisia, can lead to serious complications ranging from local disease to disseminated disease in a group of patients with primary immunodeficiency diseases. CASE REPORT A 3-month-old boy presented with persistent fever, hepato-splenomegaly and multiple osteolytic lesions. He was diagnosed with severe combined immunodeficiency disease and disseminated BCG infection. Despite anti-tubercular therapy combined with intravenous immunoglobulin, the evolution was fatal. CONCLUSION The case highlights the possible risk of such rare yet lethal complication of BCG vaccine. In suspected cases of primary immunodeficiency disease, inoculation of BCG should be postponed until appropriate screening tests exclude such diagnosis to prevent serious complications.

Abstract
Members of the Mycobacterium tuberculosis complex (MTBC) show distinct host adaptations, preferences and phenotypes despite being >99% identical at the nucleic acid level. Previous studies have explored gene expression changes between the members, however few studies have probed differences in gene essentiality. To better understand the functional impacts of the nucleic acid differences between Mycobacterium bovis and Mycobacterium tuberculosis, we used the Mycomar T7 phagemid delivery system to generate whole genome transposon libraries in laboratory strains of both species and compared the essentiality status of genes during growth under identical in vitro conditions. Libraries contained insertions in 54% of possible TA sites in M. bovis and 40% of those present in M. tuberculosis, achieving similar saturation levels to those previously reported for the MTBC. The distributions of essentiality across the functional categories were similar in both species. 527 genes were found to be essential in M. bovis whereas 477 genes were essential in M. tuberculosis and 370 essential genes were common in both species. CRISPRi was successfully utilised in both species to determine the impacts of silencing genes including wag31, a gene involved in peptidoglycan synthesis and Rv2182c/Mb2204c, a gene involved in glycerophospholipid metabolism. We observed species specific differences in the response to gene silencing, with the inhibition of expression of Mb2204c in M. bovis showing significantly less growth impact than silencing its orthologue (Rv2182c) in M. tuberculosis. Given that glycerophospholipid metabolism is a validated pathway for antimicrobials, our observations suggest that target vulnerability in the animal adapted lineages cannot be assumed to be the same as the human counterpart. This is of relevance for zoonotic tuberculosis as it implies that the development of antimicrobials targeting the human adapted lineage might not necessarily be effective against the animal adapted lineage. The generation of a transposon library and the first reported utilisation of CRISPRi in M. bovis will enable the use of these tools to further probe the genetic basis of survival under disease relevant conditions.

Abstract
Disseminated Mycobacterium infections have been commonly documented in the immunocompromised and patients who undergo treatment for non-muscle invasive bladder cancer with the Bacillus Calmette-Guerin vaccine; however, it was unique to our patient's case that she had no record of receiving vaccination in her native country, was immunocompetent, and had exposure to bovine livestock before immigrating to the United States. A 57-year-old woman with no significant medical history presented with complaints of abdominal pains and yellowing of her skin. Laboratory workup was consistent with cholestatic hepatitis. One month prior to presentation, she underwent biopsy and culture of an unspecified bladder mass, which turned out to be positive for Mycobacterium bovis. All antituberculosis medications were discontinued, without improvement of her symptoms and hepatic function tests. Subsequent liver biopsy showed the presence of granulomas with acid-fast bacilli; hence, disseminated infection was highly suspected. Multiple sputum cultures and quantiferon tests were negative, and other diagnostic tests were unremarkable. Initiation of appropriate antibiotics resulted in marked symptomatic improvement and gradual normalization of hepatic function parameters. Disseminated mycobacterial infection may present differently in patients; however, it is important to note that the source of primary infection may vary. Prompt diagnosis and treatment of these pathogens may lead to improved outcomes.

Abstract
Transitional cell carcinoma is the sixth most common cancer among men and the 17th most common cancer in women. The treatment methods for the condition range from noninvasive chemotherapy to more invasive procedures like cystectomy and complete transurethral resection of bladder tumor (TURBT) followed by intravesical Bacillus Calmette-Guérin (BCG) therapy (BCG). Intravesical BCG treatment is known to be effective as it is associated with increased survivability and long-term benefits, especially in early-stage, minimally-invasive disease. It is generally considered to be safe, even though some adverse reactions have been described. Vertebral osteomyelitis secondary to intravesical BCG therapy is a rare complication but one that has been reported in the literature. Although our patient had multiple comorbidities, including a previous vertebral compression fracture prior to treatment, complications from intravesical BCG treatment should always be considered in the differential. Further multi-center retrospective studies are needed to better ascertain its true risk given its increasing use as a treatment modality for transitional cell carcinoma.

Abstract
Livestock movements create complex dynamic interactions among premises that can be represented, interpreted, and used for epidemiological purposes. These movements are a very important part of the production chain but may also contribute to the spread of infectious diseases through the transfer of infected animals over large distances. Social network analysis (SNA) can be used to characterize cattle trade patterns and to identify highly connected premises that may act as hubs in the movement network, which could be subjected to targeted control measures in order to reduce the transmission of communicable diseases such as bovine tuberculosis (TB). Here, we analyzed data on cattle movement and slaughterhouse surveillance for detection of TB-like lesions (TLL) over the 2016-2018 period in the state of Rio Grande do Sul (RS) in Brazil with the following aims: (i) to characterize cattle trade describing the static full, yearly, and monthly snapshots of the network contact trade, (ii) to identify clusters in the space and contact networks of premises from which animals with TLL originated, and (iii) to evaluate the potential of targeted control actions to decrease TB spread in the cattle population of RS using a stochastic metapopulation disease transmission model that simulated within-farm and between-farm disease spread. We found heterogeneous densities of premises and animals in the study area. The analysis of the contact network revealed a highly connected (~94%) trade network, with strong temporal trends, especially for May and November. The TLL cases were significantly clustered in space and in the contact network, suggesting the potential for both local (e.g., fence-to-fence) and movement-mediated TB transmission. According to the disease spread model, removing the top 7% connected farms based on degree and betweenness could reduce the total number of infected farms over three years by >50%. In conclusion, the characterization of the cattle network suggests that highly connected farms may play a role in TB dissemination, although being close to infected farms was also identified as a risk factor for having animals with TLL. Surveillance and control actions based on degree and betweenness could be useful to break the transmission cycle between premises in RS.

Abstract
Mycobacterium (M.) bovis can infect cats and is a demonstrated zoonosis. We describe an outbreak of M. bovis in pet cats across England and Scotland associated with feeding a commercial raw food diet. Forty-seven cats presented with (pyo)granulomatous lesions, lymphadenopathy, pulmonary and/or alimentary disease over a one-year period where M. bovis infection was suspected or definitively diagnosed, and the cats all consumed the same specific brand of commercial raw venison pet food. Infection with M. bovis genotype 10:a was confirmed by culture and DNA typing of isolates in a small number of cases (n = 5); PCR was used in combination with or as an alternative to culture (n = 12) and/or infection with a Mycobacterium tuberculosis complex group organism was strongly suggested by positive responses to an interferon-gamma release assay (IGRA; n = 34). Asymptomatic at-risk cats were screened by IGRA, identifying a further 83 infected cats. The five culture-positive cases were distributed across areas of England and Scotland at low risk of endemic bovine tuberculosis. Investigations revealed affected cats were mainly indoor-only, and had been fed the same commercial raw food as at least part of their diet. This diet was recalled by the manufacturer due to failure of statutory meat inspection of the component venison. As far as possible, other sources of infection were explored and excluded, including wildlife contact, access to raw milk and living with people with active M. bovis infection. Four owners and one veterinary surgeon were found to have high likelihood of latent tuberculosis infection. One owner required treatment. Although it was not possible to conclusively demonstrate a zoonotic origin for these infections, neither was it possible to eliminate the possibility. Our results provide compelling evidence that the commercial raw diet of these cats was the likely route of M. bovis infection in this outbreak of cases.

Abstract
Animal tuberculosis (TB) is a multi-host zoonotic disease whose prevalence in cattle herds in Europe has been increasing, despite a huge investment in eradication. The composition of the host community is a fundamental driver of pathogen transmission, and yet this has not been formally quantified for animal TB in Europe. We quantified multi-host communities of animal TB, using stochastic models to estimate the number of infected domestic and wild hosts in three regions: officially TB-free Central-Western Europe, and two largely TB-endemic regions, the Iberian Peninsula and Britain and Ireland. We show that the estimated number of infected animals in the three regions was 290,059-1,605,612 and the numbers of infected non-bovine domestic and wild hosts always exceeded those of infected cattle, with ratios ranging from 3.3 (1.3-19.6):1 in Britain and Ireland to 84.3 (20.5-864):1 in the Iberian Peninsula. Our results illustrate for the first time the extent to which animal TB systems in some regions of Europe are dominated by non-bovine domestic and wild species. These findings highlight the need to adapt current strategies for effective future control of the disease.

Abstract
PURPOSE While guidelines support the use of maintenance bacillus Calmette-Guérin for patients with intermediate and high risk nonmuscle invasive bladder cancer, in an era of bacillus Calmette-Guérin shortage we explored the cost-effectiveness of maintenance bacillus Calmette-Guérin. MATERIALS AND METHODS A Markov model compared the cost-effectiveness of maintenance bacillus Calmette-Guérin to surveillance after induction bacillus Calmette-Guérin for intermediate/high risk nonmuscle invasive bladder cancer from a U.S. Medicare perspective. Five-year oncologic outcomes, toxicity rates and utility values were extracted from the literature. Univariable and multivariable sensitivity analyses were conducted. A willingness to pay threshold of $100,000 per quality adjusted life year was considered cost-effective. RESULTS At 5 years mean costs per patient were $14,858 and $13,973 for maintenance bacillus Calmette-Guérin and surveillance, respectively, with quality adjusted life years of 4.046 for both, making surveillance the dominant strategy. On sensitivity analysis full dose and 1/3 dose maintenance bacillus Calmette-Guérin became cost-effective if the absolute reduction in 5-year progression was greater than 2.1% and greater than 0.76%, respectively. On further sensitivity analysis full dose and 1/3 dose maintenance bacillus Calmette-Guérin became cost-effective when maintenance bacillus Calmette-Guérin toxicity equaled surveillance toxicity. In multivariable sensitivity analyses using 100,000 Monte-Carlo microsimulations, full dose and 1/3 dose maintenance bacillus Calmette-Guérin was cost-effective in 17% and 39% of microsimulations, respectively. CONCLUSIONS Neither full dose nor 1/3 dose maintenance bacillus Calmette-Guérin appears cost-effective for the entire population of patients with intermediate/high risk nonmuscle invasive bladder cancer. These data support prioritizing maintenance bacillus Calmette-Guérin for the subset of patients with high risk nonmuscle invasive bladder cancer most likely to experience progression, in particular those who tolerated induction bacillus Calmette-Guérin well. Overall, our findings support the American Urological Association policy statement to allocate bacillus Calmette-Guérin for induction rather than maintenance therapy during times of bacillus Calmette-Guérin shortage.

Abstract
Since 1986, use of a Bovine International Standard (BIS) for bovine tuberculin has been required to ensure national and international uniformity regarding the potency designation of bovine tuberculin Purified Protein Derivative (PPDb) preparations produced by multiple manufacturers. The BIS is the unique golden standard in the guinea pig potency assay, representing 100% potency, where potencies of production batches are calculated as relative potencies in comparison with the potency of the BIS which was set at 32,500 international Unit (IU) per mg. The stock supply and lifetime of the BIS is limited.The aim of this study was to develop a model to determine the potency of a newly produced in-house Reference Standard (RS) for PPDb with great accuracy in the target species (cattle) and to prove its precision and accuracy in the guinea pig potency test. First simulations were done to estimate the required number of cattle needed. Then, 30 naturally bTB infected cattle were subjected to a tuberculin skin test using multiple injections of both the RS and the BIS. Both were applied randomly in the same volume and concentration (1 dose). The potency of the RS against the BIS was directly derived from the least square means (LSMEANS) and was estimated as 1.067 (95% CI: 1.025-1.109), equal to a potency of 34,700 ± 1,400 IU/mg. In six guinea pig potency assays the RS was used to assign potencies to production batches of PPDb. Here, precision and accuracy of the RS was determined according to the parallel-line assay. Relative potencies were estimated by exponentiation of the common slope. The corresponding 95% confidence intervals were obtained according to Fieller's theorem. In sensitized guinea pigs, the relative potency of the RS against the BIS was 1.115 (95% CI: 0.871-1.432), corresponding to an absolute potency of 36,238 IU/mg (95% CI: 28,308-46,540).In conclusion: the method used to determine the potency of the RS against the BIS in naturally bTB infected cattle, resulted in a highly accurate potency estimate of the RS. The RS can be used in the guinea pig test to assign potencies to PPDb production batches with high precision and accuracy.

Abstract
BCG adverse events (BCG-AE) are rare conditions with no well-established treatment. This study aims to describe clinical characteristics and outcome of localized BCG-AE. Children with BCG-AEs who were treated at the Reference Center for Special Immunobiologicals of the Federal University of São Paulo from 2009 to 2011 were included. Patients were followed monthly until 3 months after healing. One hundred and twenty-seven patients with localized BCG-AE were followed: 67 (52.7%) had suppurative lymphadenitis; 30 (23.6%) injection-site abscess; five (3.9%) had enlarged lymph node > 3 cm; four (3.1%) had ulcer > 1 cm; and one (0.8%) had a local bacterial infection. Five patients (3.9%) had more than one BCG-AE simultaneously. Fifteen patients (11.8%) had atypical manifestations: seven wart-like lesions; five BCG reactivations; two other dermatologic lesions and one with vasomotor phenomenon. Isoniazid was used in 96 patients with typical BCG-AE (85.7%) until lesion resolution which took place 3.1 months later (in median); the healing rate was 90.6%. Patients with atypical manifestations had an individual approach. Regarding the outcome, 105/112 patients with typical AE and 13/15 patients with atypical AE had resolution of BCG-AE. Localized BCG-AE caused by BCG Moreau RJ had positive outcome when treated with a short course of isoniazid. Atypical BCG-AE are not infrequent.

Abstract
Objective: To create the first data-driven definition for those unlikely to benefit from further BCG treatment. Materials and Methods: The database created for the Phase 2 BCG-Interferon-α 2B (IFN) study was queried and BCG failure patients were identified (n = 334). Full study protocols have previously been published. Separate models were constructed for analysis of patients with any CIS (pure or concomitant) and pure papillary disease. Variables considered included age, gender, stage, grade, tumor size and focality (for papillary only), number of prior BCG courses, and prior BCG failure interval. Results: Patients with recurrent CIS within 6 months of their most recent prior BCG course (HR 2.56, p < 0.01) and ≥2 prior BCG failures (HR 1.54, p < 0.01) responded worst to repeat intravesical therapy. Those with CIS recurrence at 6–12 months did not differ from those recurring within 6 months (HR = 0.88, p = 0.71). Patients with recurrent papillary disease within 6 months (HR 1.82, p = 0.02), ≥2 BCG failures (HR 1.54, p = 0.03), and multifocal disease (HR 2.05, p < 0.01) responded worst to therapy. Patients with T1 disease remained disease free in 38% of cases (24–51% 95% CI) at 2 years with low rates of progression. Conclusions: Patients who fail two courses of BCG with either persistent or recurrent multifocal papillary disease within 6 months or CIS within 12 months of their prior BCG should be considered BCG unresponsive. Recurrent T1 disease respond reasonably well to another course with low progression rates but further investigation is warranted.

Abstract
Osteomyelitis is an infection of the bone that can involve the vertebral column. A rare cause of vertebral osteomyelitis is Mycobacterium bovis after intravesical Bacillus Calmette-Guerin (BCG) therapy for transitional cell carcinoma of the bladder. In this report, we describe the case of a 64-year-old male presenting with constitutional symptoms, progressive thoracic kyphosis, and intractable T11 and T12 radiculopathies over the proceeding six months. A CT scan revealed erosive, lytic changes of the T12 and L1 vertebrae with compression of the T12 vertebra. An MRI demonstrated T11-12 osteomyelitis with intervening discitis and extensive paraspinal enhancement with a corresponding hyperintensity on a short tau inversion recovery (STIR) sequence. A needle aspiration grew out Mycobacterial tuberculosis complex that was pansensitive to all antimicrobial agent therapies, except pyrazinamide on culture, a finding consistent with an M. bovis infection. The patient's infection and neurologic compromise resolved after transthoracic T11-12 vertebrectomies with decompression of the spinal cord and nerve roots as well as T10-L1 instrumented fusion and protracted antimicrobial therapy. The epidemiology and natural history of M. bovis osteomyelitis are reviewed and the authors emphasize a mechanism of vertebral inoculation to explain the predilection of M. bovis osteomyelitis in males after intravesical BCG therapy.

Abstract
PURPOSE The optimal dose of intravesical bacillus Calmette-Guérin for the treatment of nonmuscle invasive bladder cancer is controversial. We investigated if induction therapy with low dose bacillus Calmette-Guérin could achieve a complete response rate similar to that of standard dose bacillus Calmette-Guérin, with less toxicity and higher quality of life. MATERIALS AND METHODS After transurethral resection, patients with unresectable multiple nonmuscle invasive bladder cancer and/or carcinoma in situ were randomized to receive standard (80 mg) or low dose (40 mg) bacillus Calmette-Guérin instillation induction therapy (weekly, 8 times). The primary end point was noninferiority of low dose bacillus Calmette-Guérin with a null hypothesis of a 15% decrease in complete response rate. Secondary end points were recurrence-free survival, progression-free survival, overall survival, patient compliance, adverse events and quality of life using the EORTC QLQ-C30. RESULTS In an intent to treat analysis of 166 patients the complete response rates for low dose and standard dose bacillus Calmette-Guérin were 79% (95% CI 0.70-0.88) and 85% (95% CI 0.77-0.92), respectively. Dunnett-Gent analysis revealed that the null hypothesis of inferiority of low dose bacillus Calmette-Guérin in terms of complete response could not be rejected (p = 0.119). However, there were no significant differences between the groups in terms of recurrence, progression and overall survival. Low dose bacillus Calmette-Guérin was associated with significantly less fever (p = 0.001) and micturition pain (p = 0.047), and significantly higher quality of life scores for global quality of life, role functioning and functional impairment. CONCLUSIONS The noninferiority of low dose bacillus Calmette-Guérin was not proven. However, low dose bacillus Calmette-Guérin was associated with lower toxicity and higher quality of life compared to standard dose bacillus Calmette-Guérin in patients with nonmuscle invasive bladder cancer.

Abstract
PURPOSE Low, intermediate and high risk categories have been defined to help guide the treatment of patients with nonmuscle invasive bladder cancer (Ta, T1, CIS). However, while low and high risk disease has been well classified, the intermediate risk category has traditionally comprised a heterogeneous group that does not fit into either of these categories. As a result, many urologists remain uncertain about the categorization of patients as intermediate risk as well as the selection of the most appropriate therapeutic option for this patient population. We review the current literature and clinical practice guidelines on intermediate risk nonmuscle invasive bladder cancer and, based on our findings, provide urologists with a better understanding of this heterogeneous risk group as well as practical recommendations for the treatment of intermediate risk patients. MATERIALS AND METHODS The IBCG analyzed published clinical trials, meta-analyses and current clinical practice guidelines on intermediate risk nonmuscle invasive bladder cancer available as of September 2013. The definitions of intermediate risk, patient outcomes and guideline recommendations were considered, as were the limitations of the available literature and additional parameters that may be useful in guiding treatment decisions in intermediate risk patients. RESULTS Current definitions and management recommendations for intermediate risk nonmuscle invasive bladder cancer vary. The most simple and practical definition is that proposed by the IBCG and the AUA of multiple and/or recurrent low grade Ta tumors. The IBCG suggests that several factors should be considered in clinical decisions in intermediate risk disease, including number (greater than 1) and size (greater than 3 cm) of tumors, timing (recurrence within 1 year) and frequency (more than 1 per year) of recurrence, and previous treatment. In patients without these risk factors a single, immediate instillation of chemotherapy is advised. In those with 1 to 2 risk factors adjuvant intravesical therapy (intravesical chemotherapy or maintenance bacillus Calmette-Guérin) is recommended, and previous intravesical therapy should be considered when choosing between these adjuvant therapies. For those patients with 3 to 4 risk factors, maintenance bacillus Calmette-Guérin is recommended. It is also important that all intermediate risk patients are accurately risk stratified at initial diagnosis and during subsequent followup. This requires appropriate transurethral resection of the bladder tumor, vigilance to rule out carcinoma in situ or other potential high risk tumors, and review of histological material directly with the pathologist. CONCLUSIONS Intermediate risk disease is a heterogeneous category, and there is a paucity of independent studies comparing therapies and outcomes in subgroups of intermediate risk patients. The IBCG has proposed a management algorithm that considers tumor characteristics, timing and frequency of recurrence, and previous treatment. Subgroup analyses of intermediate risk subjects in pivotal EORTC trials and meta-analyses will be important to validate the proposed algorithm and support clear evidence-based recommendations for subgroups of intermediate risk patients.

Abstract
BACKGROUND Bacillus Calmette-Guerín (BCG) is a live attenuated vaccine to prevent tuberculosis, routinely administered at birth as part of the World Health Organization global expanded immunisation programme. Given intradermally, it can cause adverse reactions, including local, regional, distant and disseminated manifestations that may cause parental distress. Rarely, it can cause serious illness and even death. Among those patients with immunocompromised conditions, such as the human immunodeficiency virus (HIV) infection, the complication rate is even higher. OBJECTIVES To assess the effects of different interventions for treating BCG-induced disease in children. SEARCH METHODS The following databases were searched: the Cochrane Infectious Diseases Group Specialized Register and Cochrane Central Register of Controlled Trials (CENTRAL), published in The Cochrane Library (The Cochrane Library 2012, Issue 4); MEDLINE (1966 to November 2012); EMBASE (1947 to November 2012); and LILACS (1980 to November 2012). The metaRegister of Controlled Trials (mRCT) and the WHO trials search portal. Conference proceedings for relevant abstracts and experts were also contacted to identify studies. No language restrictions were applied. SELECTION CRITERIA Randomized controlled trials (RCTs) comparing any medical or surgical treatment modality for BCG-induced disease in children. DATA COLLECTION AND ANALYSIS Two authors independently evaluated titles, applied inclusion criteria, and assessed the risk of bias of studies. The primary outcomes were the failure rate of therapies for all types of BCG vaccine-induced complications and the time to resolution of illness measured in months. The secondary outcomes were death from BCG vaccine-induced disease and the all-cause mortality. Risk ratios (RRs) were used as measure of effect for dichotomous outcomes and mean differences for continuous outcomes. MAIN RESULTS Five RCTs analysing 341 children addressed the primary outcomes and were included. Four arms compared oral antibiotics to no intervention or placebo, one arm evaluated needle aspiration compared to no intervention, and another evaluated the use of locally instilled isoniazid versus oral erythromycin.Two small studies evaluated oral isoniazid; we are uncertain of whether this intervention has an effect on clinical failure (RR 1.48; 95% Confidence Interval (CI) 0.79 to 2.78; 54 participants, two studies, very low quality evidence). Similarly, for oral erythromycin, we are uncertain if there is an effect (clinical failure RR 1.03; 95% CI 0.70 to 1.53; 148 participants, three studies, very low quality evidence), and for oral isoniazid plus rifampicin (clinical failure, RR 1.20; 95% CI 0.51 to 2.83; 35 participants, one study, very low quality evidence).In patients with lymphadenitis abscess, needle aspiration may reduce clinically persistent BCG-induced disease at 6 to 9 months of follow-up (RR 0.13; 95% CI 0.03 to 0.55; 77 participants, one study, low quality evidence). In another study of patients with the same condition, aspiration plus local instillation of isoniazid reduces time to clinical cure compared to aspiration plus oral erythromycin (mean difference 1.49 months less; 95% CI 0.82 to 2.15 less; 27 participants, one study).No RCTs of HIV-infected infants with a BCG-induced disease evaluated the use of antibiotics or other therapies for reducing the rate of clinical failure or the time to clinical resolution. No data on mortality secondary to the interventions for treating BCG-induced disease were reported. AUTHORS' CONCLUSIONS It is unclear if oral antibiotics (isoniazid, erythromycin, or a combination of isoniazid plus rifampicin) are effective for the resolution of BCG-induced disease. Most non-suppurated lymphadenitis will resolve without treatment in 4 to 6 months. Patients with lymphadenitis abscess might benefit from needle aspiration and possibly local instillation of isoniazid could shorten recovery time. Included studies were generally small and could be better conducted. Further research should evaluate the use of needle aspiration and local instillation of isoniazid in fluctuant nodes. Therapeutic and preventive measures in HIV-infected infants could be important given the higher risk of negative outcomes in this group.

Abstract
Bacille Calmette-Guérin (BCG) induces potent Th1 responses with the help of interleukin (IL)-10 and IL-12 released from dendritic cells (DCs), and suppresses Th2- associated allergic reactions. However, there are still some controversies on therapeutic effects of BCG in asthmatics. This study investigated whether BCG administration to DCs suppresses IL-5 production from T cells in atopic asthmatics. DCs derived from peripheral blood of subjects were cultured with or without BCG and Dermatophagoides farinae extract. Some DCs were co-cultured with T cells in the presence of BCG or the above culture supernatants. In the atopic asthmatics, BCG significantly increased IL-10 and IL-12 production from DCs. In the presence of D. farinae extract, BCG further increased IL-10 production. BCG-induced IL-10 production was significantly higher in the atopics (n=14) than in the non-atopics (n=9). Both BCG and the BCG-treated DCs culture supernatant significantly increased IFN-gamma production from T cells. Both BCG and the supernatant from DCs+BCG+D. farinae co-cultures significantly decreased IL-5 production (all p<0.05), but the supernatant from DCs+BCG co-cultures did not. In conclusion, administration of BCG together with D. farinae extract effectively decreased IL-5 production from T cells, probably through the action of IL-10 and IL-12 released from DCs in D. farinae-sensitive asthmatics.

This study was performed to estimate the rate of boosted reaction in the two-step tuberculin skin test (TST) and to evaluate the associated factors among military personnel of South Korea, which has an intermediate burden of tuberculosis (TB) and a routine bacille Calmette-Guerin (BCG) vaccination policy. Two-step TST was performed on 264 military personnel who did not have a history of close contact to TB. Subjects with a negative reaction to the first test of <10 mm had a second TST applied 1 week later on the other forearm. A positive result (> or =10 mm) on the initial TST was observed in 126 (48%) of the subjects. A boosted reaction on the second TST developed in 32 (23%) of the 124 subjects with a negative initial TST. In multiple logistic regression analysis, the size of the initial TST reaction was the only factor associated with a boosted reaction on the second TST. The high rate of boosted reaction among healthy adults in South Korea suggests that two-step TST should be performed to assess the baseline TST reactivity in settings with an intermediate burden of TB and routine BCG vaccination policy, especially among subjects with an initial TST reaction that is > or =5 mm.

Abstract
Bacillus Calmette-Guerin (BCG) is reported to suppress Th2 response and asthmatic reaction. Dendritic cells (DCs), the major antigen-presenting cells, infections with BCG are known to result in inducing various cytokines. Thus, DCs are likely to play a role in the effects of BCG on asthma. This study aims at investigating that cytokine milieu secreted by BCG-treated DCs directly enhances allergen-specific Th1 response and/or suppresses Th2 response in allergic asthma. DCs and CD3+ T cells were generated from Dermatophagoides farinae-sensitive asthmatics. DCs were cultured with and without BCG and subjected to flow cytometric analysis. IL-12 and IL-10 were determined from the culture supernatants. Some DCs were cocultured with T cells in the presence of D. farinae extracts after adding the culture supernatants from BCG-treated DCs, and IL-5 and IFN-gamma were determined. BCG-treated DCs enhanced significantly the expressions of CD80, CD86, and CD40, and the productions of IL-12 and IL-10. Addition of culture supernatants from BCG-treated DCs up-regulated production of IFN-gamma by T cells stimulated by DCs and D. farinae extracts (p<0.05), but did not down-regulate production of IL-5 (p>0.05). The cytokine milieu secreted by BCG-treated DCs directly enhanced allergen-specific Th1 response, although did not suppress Th2 response.

Abstract
The anti-idiotypic antibody (Ab2) prepared against the anti-BCG monoclonal antibody (mAb) (Ab1) exhibited potential vaccine activity against Meth A fibrosarcoma that shared a common antigen(s) with Mycobacterium bovis strain bacillus Calmette Guèrin (BCG). Mice vaccinated with the anti-idiotypic antibody (Ab2) were protected significantly against growth of the transplanted Meth A tumor (66%), and the presence of anti-(anti-idiotypic antibody) (Ab3) was proved in the Ab2-vaccinated mice by enzyme-linked immunosorbent assay and indirect immunofluorescence analyses using unabsorbed or absorbed sera against the BCG antigen(s) and Meth A tumor cells. This indicated that the anti-idiotypic antibody (Ab2) mimicked the structures of the BCG antigen(s) and behaved as the BCG antigen(s) to induce the Ab1-like antibody (Ab3) in vivo. Presumably the Ab2-induced Ab3 plays a significant role in preventing growth of the transplanted tumor in animals. By contrast, the control mice treated with normal mouse serum failed to inhibit the tumor growth. These results suggest the possible development of a tumor vaccine from the anti-idiotypic antibody (Ab2) prepared against the anti-BCG monoclonal antibody, for tumors sharing a common antigen(s) with Mycobacterium bovis strain BCG.

Abstract
Strain-2 guinea pigs, each with microscopic deposits of line 10 hepatocarcinoma in the liver, were treated by ID immunization with a mixture of irradiated tumor cells and an oil-in-water emulsion containing cell walls of Mycobacterium bovis strain Bacillus Calmette-Guérin (BCG CWE). Injection of line 10 hepatoma cells into the hepatic portal vein led to the development of tumor foci in the liver, metastasis in the hepatic lymph node, malignant ascites, and death. Active immunization using irradiated line 10 cells and BCG CWE was effective therapy when administered 1, 7, and 14 days after intraportal injection of line 10 cells. Effective immunization required both irradiated line 10 tumor cells and the BCG cell wall emulsion. Immunization with BCG CWE admixed with irradiated line 1 tumor cells, a hepatoma antigenically distinct from line 10, did not prevent outgrowth of line 10 deposits in the liver. Animals rendered free of disease could reject a challenge of line 10 tumor cells but not of line 1 tumor cells.

Abstract
The immunological and pathological responses of guinea pigs to an intramural colonic injection of emulsions containing cell wall (CW) extracts of Mycobacterium bovis BCG and mineral oil were studied from week 1 to week 36 post-inoculation. The emulsions contained variable concentrations of BCG CW attached to (lipid-phase), or separate from (aqueous-phase), the mineral oil. Delayed cutaneous hypersensitivity to PPD was present throughout the course of the study in a variable percentage of guinea pigs inoculated with either type of emulsion. PPD-induced blast transformation of peripheral blood lymphocytes, studied in guinea pigs which received lipid-phase emulsion, was also detectable throughout the course of the study, with maximal response seen 2 weeks post-inoculation. The intracolonic inoculations were well tolerated, with the exception of the most concentrated lipid-phase emulsion (3 mg/ml BCG CW and 5% oil), after which one of eight guinea pigs died due to a colonic impaction and rupture at the site of inoculation. The pathological response to either type of emulsion was a focal granulomatous colitis, which tended to be more severe as the concentration of BCG CW and oil increased. Extracolonic lesions were usually limited to a granulomatous lymphadenitis of lymph nodes draining the injection site; however, the most concentrated lipid-phase emulsion occasionally produced granulomatous inflammatory foci in the liver and lungs. In general, the lesions induced by the lipid-phase emulsions were more severe than those induced by aqueous-phase emulsions, but the intensity of both types of lesions peaked at 2 or 4 weeks post-inoculation. It was concluded that the guinea pig may serve as a useful model to study BCG immunotherapy of colonic neoplasms, since intracolonic injection of BCG CW resulted in systemic immunity toward mycobacterial antigens and a localized accumulation of macrophages without untoward complications.
