Candidemia Following Ureteric Stent Placement in a Patient With Type 2 Diabetes Treated With Canagliflozin

Sodium-glucose Co-transporter-2 Inhibitors Causing Candida tropicalis Fungemia and Renal Abscess

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are a relatively newer class of medications, approved by the U.S. Food and Drug Administration in 2013 to treat type 2 diabetes mellitus. Over the past few years, the indications for SGLT2i have been expanded to decrease the risk of kidney disease and cardiovascular disease. SGLT2i are associated with an increased risk of euglycemic diabetic ketoacidosis, urinary tract infections, and genital mycotic infections. There are a few case reports of severe invasive fungal infections due to Candida in patients using SGLT2i. We present the case of Candida tropicalis fungemia and renal abscess in a patient on an SGLT2i.

Uncommon Complications of Cystoscopy: Presentations of Concurrent Perirenal Hematoma and Candida albicans Sepsis

Subcapsular hematoma (SRH) or perirenal hematoma (PRH) can be seen after trauma, interventional radiological procedures, urological procedures, anticoagulant medications, coagulation disorders, infections, and spontaneously in some patients. Within the urological procedures, PRH can occur after percutaneous nephrolithotomy and extracorporeal shortwave lithotripsy but has only been reported a few times after cystoscopy/ureteroscopy. Here, we present the case of PRH as a complication from cystoscopy with retrograde pyelography in a patient with underlying chronic kidney disease (CKD) and an extensive surgical history for nephrolithiasis. In addition to this, our patient had a further complication of sepsis by Candida albicans, of which the source is proven to be urinary, and it appears that the fungemia was triggered during the procedure as well. The diagnosis was confirmed by abdominal computed tomography (CT), and PRH was proven to resolve with conservative management on repeat imaging months later.

Risk factors for candidaemia: A prospective multi-centre case-control study

OBJECTIVES

Candidaemia carries a mortality of up to 40% and may be related to increasing complexity of medical care. Here, we determined risk factors for the development of candidaemia.

METHODS

We conducted a prospective, multi-centre, case-control study over 12 months. Cases were aged ≥18 years with at least one blood culture positive for Candida spp. Each case was matched with two controls, by age within 10 years, admission within 6 months, admitting unit, and admission duration at least as long as the time between admission and onset of candidaemia.

RESULTS

A total of 118 incident cases and 236 matched controls were compared. By multivariate analysis, risk factors for candidaemia included neutropenia, solid organ transplant, significant liver, respiratory or cardiovascular disease, recent gastrointestinal, biliary or urological surgery, central venous access device, intravenous drug use, urinary catheter and carbapenem receipt.

CONCLUSIONS

Risk factors for candidaemia derive from the infection source, carbapenem use, host immune function and organ-based co-morbidities. Preventive strategies should target iatrogenic disruption of mucocutaneous barriers and intravenous drug use.

Clinical Features of Endogenous Endophthalmitis Secondary to Minimally Invasive Upper Urinary Tract Calculus Removal

PURPOSE

To evaluate endogenous endophthalmitis clinical features following minimally invasive removal of upper urinary tract calculi.

METHODS

Medical records of twelve patients (17 eyes) with endogenous endophthalmitis secondary to minimally invasive upper urinary tract calculus removal were retrospectively reviewed.

RESULTS

Diabetes mellitus was found in 7 patients (58%). 10 patients (83%) suffered from fever. The stone extraction and ocular symptom onset interval ranged from 2 to 22 days. All eyes presented as vitritis and fluffy yellow-white retinal exudates. Hypopyon was only found in 3 eyes (18%). 5 patients (42%) were misdiagnosed as uveitis which led to mismanagement. Ocular fluids were culture positive for only C. albicans in 12 eyes (71%). 10 of 12 eyes (83%) with silicon oil tamponade obtained a final BCVA≥0.05.

CONCLUSIONS

C. albicans was the most common endogenous endophthalmitis pathogen after urinary calculus removal by minimally invasive surgery. Pars plana vitrectomy with silicon oil tamponade may be helpful to achieve a favorable visual outcome. Routine ophthalmologic evaluation by the uveitis or vitreoretinal specialist may be necessary within 2 weeks after the urological procedures.
