    尽管有效的化疗和其他可用的肿瘤治疗,非肌肉浸润性膀胱癌(NMIBC)的复发率仍然很高,多达60%的患者需要在24个月内使用BCG或其他药物重复膀胱内治疗。植物配方LCS103对膀胱癌细胞具有抗癌活性,尽管其临床疗效仍有待证明。连续对30例膀胱癌患者进行回顾性检查,其中20名患者(18名患有NMIBC,2患有转移性疾病)用LCS103治疗14个月至16年,除了他们的常规肿瘤护理。只有3例患者(15%)在开始植物治疗后出现单一肿瘤复发,与11例患者报告的治疗前复发相反(55%;范围,1-5).大多数接受LCS103治疗的患者报告泌尿系统症状的严重程度降低(疼痛,频率,尿急;和夜尿症),以及虚弱和疲劳,和一般的福祉。没有不良事件与使用植物配方有关。需要进一步的前瞻性随机试验来确认和更好地理解这些初步发现。
    Despite effective chemotherapy and other available oncology treatments, recurrence rates for non-muscle invasive bladder cancer (NMIBC) remain high, with as many as 60% of patients requiring repeat intravesical treatments with BCG or other agents within a 24-month period. The botanical formula LCS103 has displayed anti-cancer activity on bladder cancer cells, though its clinical efficacy remains to be proven. A consecutive series of 30 patients with bladder cancer was examined retrospectively, of which a cohort of 20 patients (18 with NMIBC, 2 with metastatic disease) was treated with LCS103 for between 14 months and 16 years, in addition to their conventional oncology care. Only 3 patients (15%) had a single tumor recurrence after initiation of the botanical treatment, as opposed to pre-treatment recurrence reported among 11 patients (55%; range, 1-5). The majority of LCS103-treated patients reported reduced severity for urological symptoms (pain, frequency, and urgency on urination; and nocturia), as well as for weakness and fatigue, and for general wellbeing. No adverse events were associated with use of the botanical formula. Further prospective randomized trials are needed to confirm and better understand these initial findings.

    膀胱内滴注卡介苗(BCG)是一种针对浅表性膀胱癌的免疫疗法。在这里,我们描述了一例播散性卡介苗感染,在第一次卡介苗注射后立即发展。一名被诊断患有非浸润性膀胱癌的76岁男子接受了膀胱内BCG滴注;当晚晚些时候,他出现了高烧和全身性关节痛。全身检查没有发现任何传染源,和异烟肼的联合治疗,rifabutin,乙胺丁醇是在收集他的血液后开始的,尿液,骨髓,和分枝杆菌培养的肝活检样本。三周后,在尿液和骨髓样本中检测到牛分枝杆菌,肝活检的病理检查显示多发性小上皮肉芽肿与局灶性多核巨细胞,导致诊断为播散性BCG感染。患者在长期抗分枝杆菌治疗后康复,无明显后遗症。大多数播散性卡介苗感染病例发生在几剂卡介苗注射后,据报道,它的发病因病例而异,从几天到几个月不等。由于仅在第一次BCG注射后数小时观察到疾病发作,所以本病例是值得注意的。虽然罕见,在膀胱内滴注BCG治疗后的任何时候,都应将播散性BCG感染的发展视为患者的鉴别诊断。
    Intravesical Bacillus Calmette-Guérin (BCG) instillation is an established immunotherapy for superficial bladder cancer. Herein, we describe a case of disseminated BCG infection that developed immediately after the first BCG injection. A 76-year-old man diagnosed with non-invasive bladder cancer underwent intravesical BCG instillation; he developed high fever and systemic arthralgia later that night. General examination did not reveal any infectious sources, and a combination therapy of isoniazid, rifabutin, and ethambutol was initiated after collecting his blood, urine, bone marrow, and liver biopsy samples for mycobacterial cultures. Three weeks later, Mycobacterium bovis was detected in the urine and bone marrow samples, and pathological investigation of liver biopsy revealed multiple small epithelial granulomas with focal multinucleated giant cells, leading to a diagnosis of disseminated BCG infection. The patient recovered after long-term antimycobacterial therapy without remarkable sequelae. Most cases of disseminated BCG infection occur after several doses of BCG injections, and its onset reportedly varies among cases, ranging from a few days to several months. The present case was notable as disease onset was observed only a few hours after the first BCG injection. Although rare, development of disseminated BCG infection should be considered as a differential diagnosis in patients at any time after intravesical BCG instillation therapy.

    高风险非肌肉浸润性膀胱癌(NMIBC)的标准治疗方法是经尿道膀胱切除术(TURB),然后滴注卡介苗(BCG)。膀胱内滴注BCG后腹膜结核的发生极为罕见且难以诊断。
    我们报告了一例79岁的男性患有肾和膀胱尿路上皮细胞癌(UCC)的病例,该病例在连续TURB和肾输尿管切除术后进行膀胱内滴注BCG后发展为腹膜结核。进一步的调查发现未确诊的膀胱漏。
    此病例提醒泌尿科医师在膀胱手术后不久给予卡介苗时怀疑尿路上皮不连续。
    UNASSIGNED: The standard treatment for high-risk non-muscle-invasive bladder cancer (NMIBC) is trans-urethral resection of the bladder (TURB) followed by instillation of Bacillus Calmette-Guérin (BCG). The occurrence of peritoneal tuberculosis after intravesical BCG instillation is extremely rare and difficult to diagnose.
    UNASSIGNED: We report the case of a 79-year-old man with urothelial cell carcinoma (UCC) of the kidney and bladder who developed peritoneal tuberculosis after consecutive TURB and nephroureterectomy followed by intravesical BCG instillation. Further investigation revealed an undiagnosed bladder leak.
    UNASSIGNED: This case serves as a reminder for urologists to be suspicious for urothelium discontinuity when administering BCG shortly after bladder surgery.

    尚不清楚膀胱内卡介苗(BCG)是否在人母乳中排泄。美国FDA主张因潜在的不良反应而停止护理。据报道,一名患有膀胱癌的哺乳期妇女选择接受BCG膀胱内免疫治疗,并否认停止护理新生儿。一名42岁女性在怀孕第36周时出现肉眼血尿。成像显示膀胱有肿块。分娩后进行膀胱镜检查和切除术。病理检查提示pT1尿路上皮癌。在对治疗方案进行了彻底讨论之后,患者选择膀胱内BCG。婴儿在治疗前2周接受皮内BCG疫苗接种。因此,患者可以母乳喂养,而不会对自己或婴儿造成任何意外后遗症。
    卡介苗(BCG)是结核病疫苗。它含有活的但减毒的结核杆菌。它也用于膀胱癌的治疗,直接滴入膀胱.BCG激活膀胱内的局部免疫反应以对抗癌细胞。在哺乳期妇女中,BCG滴入膀胱是否会导致杆菌在母乳中排泄的问题仍然未知。美国FDA建议,由于潜在的不良反应,在接受卡介苗治疗时停止母乳喂养。作者报告了一名患有膀胱癌的哺乳期妇女,她选择接受BCG免疫治疗。婴儿在患者治疗前2周接受了预防性皮肤卡介苗接种。最终,她能够在母乳喂养孩子的同时完成治疗,对婴儿或她自己没有任何负面影响。据作者所知,这是第一篇文章显示在BCG治疗膀胱癌期间母乳喂养可能是安全的.
    It is unknown whether intravesical bacillus Calmette-Guérin (BCG) is excreted in human breast milk. The US FDA advocates ceasing nursing due to potential adverse reactions. A lactating woman with bladder cancer who elected to receive intravesical immunotherapy with BCG and denied having ceased nursing her newborn is reported. A 42-year-old woman presented with macroscopic hematuria in the 36th week of her pregnancy. Imaging revealed a mass in the bladder. Cystoscopy and resection were performed after childbirth. Pathological examination revealed pT1 urothelial carcinoma. After a thorough discussion of the treatment options, the patient elected intravesical BCG. The infant received intradermal BCG vaccination 2 weeks before the treatment. As a result, the patient could breastfeed without any inadvertent sequela on herself or the baby.
    Bacillus Calmette-Guérin (BCG) is tuberculosis vaccine. It contains live but attenuated tubercle bacillus. It is also used for bladder cancer treatment, where it is directly instilled into the bladder. BCG activates the local immune response within the bladder to fight cancer cells. The issue of whether BCG instillations into the bladder cause the bacillus to be excreted in breast milk in a lactating woman remains unknown. The US FDA suggests discontinuing breastfeeding when undergoing treatment with BCG due to potential adverse reactions. The authors report on a breastfeeding woman with bladder cancer who elected to receive BCG immunotherapy. The baby received a precautionary dermal BCG vaccination 2 weeks before the patient\'s treatment. Ultimately, she was able to complete her treatment while breastfeeding her child without any negative effects on the infant or herself. To the best of the authors\' knowledge, this is the first article showing that breastfeeding may be safe during BCG treatment for bladder cancer.

    该患者是一名70岁的女性,于2020年5月接受了经尿道膀胱肿瘤切除术。她被诊断出患有尿路上皮癌(高级别,pT1病理)。我们于同年8月第二次经尿道切除术后开始卡介苗(BCG)膀胱内输注(80mgTokyo菌株)。在服用卡介苗期间,排尿时疼痛持续存在,在完成六个剂量后恶化了。患者因背部和颈部疼痛和身体运动困难而住院。在录取的时候,观察到双侧结膜炎。患者被诊断为与BCG膀胱内注射治疗相关的反应性关节炎,观察到三种典型症状(双侧结膜炎,尿道炎,多关节炎)。患者接受强的松龙和非甾体抗炎药治疗关节炎,但症状没有改善。我们给予柳氮磺吡啶,她的反应性关节炎得到改善。
    The patient was a 70-year-old woman who underwent transurethral resection of bladder tumor in May 2020. She was diagnosed with urothelial carcinoma (high grade, pT1 by pathology). We started bacillus Calmette-Guerin (BCG) intravesical infusion (80 mg Tokyo strain) in August of the same year after a second transurethral resection. Pain during urination persisted during the administration of BCG, and it worsened after the completion of six doses. The patient was hospitalized with back and neck pain and difficulty in physical movement. At the time of admission, bilateral conjunctivitis was observed. The patient was diagnosed with reactive arthritis associated with BCG intravesical injection therapy, as three typical symptoms were observed (bilateral conjunctivitis, urethritis, polyarthritis). The patient was treated with prednisolone and non-steroidal anti-inflammatory drugs for arthritis, but the symptoms did not improve. We administered salazosulfapyridine and her reactive arthritis improved.

    背景:卡介苗(BCG)是牛分枝杆菌的减毒活菌株,已被用作针对几种恶性肿瘤的免疫疗法。特别是,膀胱内滴注BCG已成为公认的膀胱癌辅助治疗方法。BCG血管感染是BCG治疗的罕见并发症。这些感染的许多方面,包括演讲,危险因素,和治疗策略,知之甚少。通过对现有文献的系统回顾,我们旨在确定这种情况与患者特征之间的潜在关联,介绍,其治疗,和结果。
    方法:我们搜索了PubMed,MEDLINE,和Embase数据库从开始到2021年6月的BCG血管感染病例。包括BCG血管感染的英语报告。
    结果:共纳入74例BCG血管感染病例。73例(99%)为男性患者,所有这些人都通过膀胱滴注暴露于卡介苗。50例(68%)在暴露于BCG后超过12个月被诊断出。26例(35%)在诊断时出现动脉破裂。在37例(50%)病例中,非血管部位同时存在BCG感染。BCG血管感染最常见的部位是腹主动脉(57%),假体移植物(15%),和胸主动脉(12%)。BCG感染最常见的治疗方法是开放式修复,原位置换腹主动脉和腔内修复胸主动脉。30天死亡率,在报告这些数据的59个案例中,是10%。
    结论:我们观察到卡介苗血管感染的许多方面与其他形式的血管感染相似。破裂或瘘的高发生率以及腹主动脉受累的倾向及其预后与其他血管感染中描述的相似。然而,我们的研究还强调了BCG血管感染的2个特质特征:与男性和并发肌肉骨骼感染的相关性.
    BACKGROUND: Bacillus Calmette-Guerin (BCG) is a live attenuated strain of Mycobacterium bovis that has been used as immunotherapy against several malignancies. In particular, intravesical instillation of BCG has become a well-accepted adjuvant treatment for bladder cancer. BCG vascular infections are a rare complication of BCG therapy. Many aspects of these infections, including the presentations, risk factors, and treatment strategies, are poorly understood. Through a systematic review of the existing literature, we aimed to identify potential associations between this condition and patient characteristics, presentations, its treatments, and outcomes.
    METHODS: We searched the PubMed, MEDLINE, and Embase databases for cases of BCG vascular infections from inception to June 2021. English-language reports of BCG vascular infections were included.
    RESULTS: A total of 74 cases of BCG vascular infections were included. Seventy-three (99%) cases were male patients, all of whom were exposed to BCG through bladder instillation. Fifty (68%) cases were diagnosed more than 12 months after exposure to BCG. Twenty-six (35%) cases presented with arterial rupture at the time of diagnosis. Concurrent BCG infections in nonvascular locations were present in 37 (50%) cases. The most common locations of BCG vascular infection were the abdominal aorta (57%), prosthetic grafts (15%), and thoracic aorta (12%). The most common treatment for BCG infection was open repair with synthetic graft in situ replacement for the abdominal aorta and endovascular repair for the thoracic aorta. The 30-day mortality, among the 59 cases where these data were reported, was 10%.
    CONCLUSIONS: We observed that many aspects of BCG vascular infections are similar to other forms of vascular infections. The high incidence of rupture or fistulation and the propensity toward abdominal aortic involvement and its prognosis are similar to those described in other vascular infections. However, our study also highlights 2 idiosyncratic features of BCG vascular infections: association with male sex and concurrent musculoskeletal infections.

    结核分枝杆菌复合体(MTBC)假阳性培养物通常归因于实验室交叉污染,但是很少报告手术室中的交叉污染(OR)。我们报告了对我们病例患者的手术室交叉污染的调查,他接受了慢性手术干预,左侧乳腺病变。尽管该病例患者从未接受过牛分枝杆菌卡介苗(BCG)疫苗或化疗,随后的手术样品培养物通过高效液相色谱法鉴定为MTBC,通过基因分型鉴定为牛分枝杆菌BCG型.发起了一项合作假阳性调查,我们从接受BCG膀胱内滴注的原始病例中发现了OR中的交叉污染事件。临床医生,公共卫生,感染控制人员应该意识到手术室中MTBC交叉污染很少,但有可能,并应认识到进行彻底假阳性调查的重要性。
    Mycobacterium tuberculosis complex (MTBC) false-positive cultures are commonly attributed to laboratory cross-contamination, but cross-contamination in the operating room (OR) is seldom reported. We report an investigation of cross-contamination in the OR for our case patient, who underwent surgical intervention for a chronic, left-sided breast lesion. Although the case patient had never received Mycobacterium bovis bacillus Calmette-Guérin (BCG) vaccine or chemotherapy, a subsequent surgical sample culture was identified as MTBC by high-performance liquid chromatography and M. bovis BCG-type by genotyping. A collaborative false-positive investigation was initiated, and we discovered a cross-contamination event in the OR from a source case who received BCG intravesical instillation. Clinicians, public health, and infection control staff should be aware that MTBC cross-contamination in the OR is rare, but possible, and should recognize the importance of conducting thorough false-positive investigations.
