Intravesical instillation of bacillus Calmette-Guérin (BCG) is a crucial adjunctive therapy in the treatment of bladder carcinoma. Its systemic complications are rare but include disseminated Mycobacterium bovis ( M. bovis ) infections, the diagnosis of which is a challenging task that requires keen clinical awareness. We report the case of an adult male treated with BCG who presented with fever, nonspecific constitutional symptoms, hepatic cytolysis, and cholestasis. After a detailed workup, the diagnosis was made of disseminated M. bovis infection with hepatic, pulmonary, renal, and ureteral involvement. Prompt anti-tuberculosis treatment resulted in clinical and analytical improvement. This case highlights the importance of early recognition of this serious complication in patients with BCG exposure, as well as the difficulty in confirming the diagnosis for proper treatment., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Henriques Mendes et al.)

Introduction: Stillbirth has been documented as an outcome of SARS-CoV-2 infection in pregnancy. Placental hypoperfusion and inflammation secondary to maternal immune response seem to play a role in the cascade of events that contribute to fetal death. The aim of our study is to report a perinatal outcome of SARS-CoV-2 infection in pregnancy adding information to the pool of data on COVID-19 pregnancy outcomes. Case Presentation . This is the first stillbirth case series occurring in pregnant women infected with SARS-CoV-2 in a Portuguese cohort. Between April 2020 and March 2021, we had 2680 births in our centre, of which 130 (4.95%) involved mothers infected with SARS-CoV-2. Of total births, there were 14 stillbirths (0.52%), accounting for the highest stillbirth rate we have had in the last 5 years. Among these 14 stillbirths, 5 (35.71%) occurred in SARS-CoV-2-infected mothers. We report the clinical features and placental histopathologic findings of 4 stillbirth cases that occurred in our hospital. Discussion . The stillbirth rate among SARS-CoV-2-infected pregnant women (5/130; 3.84%) was significantly increased compared to noninfected patients (9/2550; 0.35%). Most women (3/4) were asymptomatic for COVID-19, a surprising outcome, given the current literature. All cases had histologic exams showing placental signs of vascular malperfusion, although we acknowledge that 3/5 had obstetric conditions related to placental vascular impairment such as preeclampsia and HELLP syndrome., Conclusion: Stillbirth can be a perinatal consequence of SARS-CoV-2 infection in pregnancy, even in asymptomatic patients. We urge more studies to explore the association between SARS-CoV-2 infection and the risk of stillbirth., Competing Interests: The authors declare that they have no conflict of interest regarding the publication of this case series., (Copyright © 2022 Ana Rita Mira et al.)
