Syphilis and nephrotic syndrome: A case report and literature review.

A 31-year-old woman who had unprotected sexual intercourse with multiple partners presented to our hospital with bilateral leg edema, weight gain, and eyelid edema. One month before her visit, she had a fever of 38.0 â„ƒ for 2 days, and 1 week before her visit, she experienced fatigue. The presence of hypoalbuminemia, proteinuria, and leg edema raised the suspicion of nephrotic syndrome along with syphilis. She was treated with doxycycline for secondary nephrotic syndrome caused by secondary syphilis. Secondary syphilis is a well-known but rare cause of secondary nephrotic syndrome, and the occurrence rate, risk factors, and timing of occurrence are unknown. Therefore, we have supplemented this case report with a concise review of the relevant literature that delineates the use of appropriate antibiotic therapy in the management of secondary nephrotic syndrome derived from secondary syphilis.

Uncommon but Clinically Significant: Bacillus Calmette-Guerin (BCG) Infection of the Urinary Tract and its Impact on Quality of Life.

BACKGROUND The intravesical administration of bacillus Calmette-Guerin (BCG), an attenuated live strain of Mycobacterium bovis, is an immunotherapy given for superficial bladder cancer and is generally well tolerated and widely used. However, BCG sometimes causes local infections, such as cystitis and prostatitis or systemic infection. Because BCG infection is a rare complication of intravesical BCG instillation, the combination of an anti-tuberculous regimen and its duration of are unknown. CASE REPORT We describe 2 cases of BCG infection localized to the urinary tract. Case 1 was a 77-year-old man with BCG infection of the bladder and prostate. Combination therapy of anti-tuberculous agents with isoniazid, rifampicin, and ethambutol did not improve his symptoms, and his quality of life was significantly impaired from the symptoms of BCG infection; therefore, he underwent total resection of the bladder and prostate. Case 2 was an 84-year-old man with BCG infection of the bilateral ureter and bladder. It took 15 months for his symptoms to improve, but combination therapy with isoniazid, rifabutin, and ethambutol improved his condition completely. CONCLUSIONS Although BCG infection of the urinary tract is a rare complication, it is clinically important because it directly affects the quality of life of patients and requires a longer duration of treatment, depending on the symptoms. Tissue cultures are also difficult to culture, making a definitive diagnosis challenging. If the symptoms of BCG infection are not controlled, surgery can be necessary even if it is not a complication of a vital organ.

Probiotic-related Clostridium butyricum bacteremia: a case report and literature review.

We report three cases of Clostridium butyricum bacteremia associated with taking C. butyricum-related probiotics. We performed a literature review and found 11 cases of C. butyricum bacteremia including our cases. Nine cases related to probiotics. We should consider that probiotics may infect clinically unstable patients.

Effectiveness of Extended or Continuous vs. Bolus Infusion of Broad-Spectrum Beta-Lactam Antibiotics for Febrile Neutropenia: A Systematic Review and Meta-Analysis.

This systematic review aimed to compare extended infusion or continuous infusion with bolus infusion for febrile neutropenia (FN). We included clinical trials comparing extended or continuous infusion with bolus infusion of beta-lactam antibiotics as empirical treatment for FN and evaluated the clinical failure, all-cause mortality, and adverse event rates. Five articles (three randomized controlled trials (RCTs) and two retrospective studies) from 2014 to 2022 were included. Clinical failure was assessed with a risk ratio (RR) (95% coincident interval (CI)) of 0.74 (0.53, 1.05) and odds ratio (OR) (95% CI) of 0.14 (0.02, 1.17) in the 2 RCTs and retrospective studies, respectively. All-cause mortality was assessed with an RR (95% CI) of 1.25 (0.44, 3.54) and OR (95% CI) of 1.00 (0.44, 2.23) in the RCTs and retrospective studies, respectively. Only 1 RCT evaluated adverse events (with an RR (95% CI) of 0.46 (0.13, 1.65)). The quality of evidence was "low" for clinical failure and all-cause mortality in the RCTs. In the retrospective studies, the clinical failure and all-cause mortality evidence qualities were considered "very low" due to the study design. Extended or continuous infusion of beta-lactam antibiotics did not reduce mortality better than bolus infusion but was associated with shorter fever durations and fewer adverse events.
