SUMMARY: For several decades, intravesical Bacillus Calmette–Guérin (iBCG) immunotherapy has been the gold standard adjuvant treatment for high-risk and selected intermediate-risk patients with non-muscle-invasive bladder cancer (NMIBC). In this review, the mechanisms of iBCG immune-mediated anti-cancer activity and resistance are presented. Furthermore, a literature review of short-term and systemic iBCG-related side effects was performed. A high incidence (75.5%) of iBCG-related short-term, self-limiting adverse events was observed, while more severe iBCG-related local/systemic complications (iBCG-rL/SCs) that required medical treatment or hospitalization occurred at a lower rate (2.35%). Disseminated was the most common form of iBCG-rSCs, while two-thirds of the cases were classified as infectious. The implementation of molecular-based techniques resulted in significantly higher diagnostic rates. Anti-tuberculous treatment (ATT) is the mainstay of treatment, while in patients with any iBCG-rL/SC form involving the vasculature, ATT should be combined with surgery. Local and osteoarticular forms have the lowest mortality, but their management necessitates severe and debilitating surgical procedures. The overall iBCG-attributed mortality in patients with iBCG-rL/SC was 7.4%, with disseminated, vascular, and lung involvements exhibiting the highest rates. Given the global shortage of BCG for the last two decades, as well as the paucity of effective options for iBCG-refractory or relapsing NMIBC patients, new therapeutic strategies are being tested with promising early results.

Backround. Spontaneous bacterial peritonitis (SBP) is a serious complication in cirrhotic patients. Gram (–) (E. coli, Klebsiella pneumoniae), and Gram (+) (Streptococci, Staphylococci) bacteria are most frequently cultured from patients'ascites. Listeria monocytogenes (Lm) is scarcely reported as a causative agent. Objective. Our objective is to describe Lm peritonitis as a clinical entity, including its presentation, clinical features, treatment, and the potential factors that might affect survival outcome. Material and methods. Data sources: MEDLINE, Scholar.Google, Scopus databases, including English, Spanish, French, and German language papers published between 1966 and June 2011, and reference lists. Data extraction: investigators abstracted details about medical history, disease presentation, laboratory data, treatment and outcome. Data synthesis: One-hundred and twenty-eight cases with known survival outcome – eighty-six cirrhotics, seventeen individuals undergoing continuous ambulatory peritoneal dialysis and another twenty-five with other or no underline condition were reviewed. An additional number of twenty-five cases with unknown outcome were searched in Listeria studies published from 1990 to 2009 and were only used for calculating worldwide distribution. Conclusion. Cirrhotics, mostly alcoholics, presented with fever and abdominal pain. Those who succumbed had significantly higher peripheral WBC count (15622 vs. 8155 cells/mm³, p = 0.01) and (%) polymorphonuclear cells in differential count (83.3 vs. 71%, p = 0.001). Higher mortality was experienced in those with comorbidities, and those who presented with encephalopathy. Lower mortality was experienced in patients on continuous ambulatory peritoneal dialysis. Ascites was neutrocytic in 86% of the samples. In the sum of the cases mortality was 27.3%, with significantly highest rates in the elderly, in patients with bacteremia, immunosuppression, hematological malignancies, and lowest rates in those who presented with abdominal pain and in diabetics (type I or II). The latter observation was surprising and could be considered a single fortuitous fact. Initial appropriate treatment was associated with significantly better outcome (p = 0.002) than inappropriate; combination therapy with an aminoglycoside was superior to monotherapy (p = 0.038).
