    Background: Colistin (COL) has become the backbone of the treatment of infections due to extensively drug-resistant (XDR) Gram-negative bacteria. The most common restriction to its use is acute kidney injury (AKI). Methods: We conducted a retrospective cohort study to evaluate risk factors for new-onset AKI in patients receiving COL. The cohort consisted of 198 adults admitted to 9 referral hospitals between January 2010 and October 2012 and treated with intravenous COL for >= 72 h. Patients with no pre-existing kidney dysfunction were compared in terms of risk factors and outcomes of AKI graded according to the RIFLE criteria. Logistic regression analysis was used to identify associated risk factors. Results: A total of 198 patients met the inclusion criteria, of whom 167 had no pre-existing kidney dysfunction; the mean patient age was 58.77 (+/- 18.98) y. Bloodstream infections (34.8%) and ventilator-associated pneumonia (32.3%) were the 2 most common indications for COL use. New-onset AKI developed in 46.1% of the patients, graded as risk (10%), injury (15%), and failure (21%). Patients with high Charlson co-morbidity index (CCI) scores (p = 0.001) and comparatively low initial glomerular filtration rate (GFR) estimations (p < 0.001) were more likely to develop AKI, but older age (p = 0.001; odds ratio 5.199, 95% confidence interval 2.684-10.072) was the major predictor in the multivariate analysis. In-hospital recovery from AKI occurred in 58.1%, within a median of 7 days. Conclusions: COL-induced nephrotoxicity occurred significantly more often in patients older than 60 y of age and was related to low initial GFR estimations and high CCI scores, which were basically determined by age.

    Epidemiology and outcomes of Candida-associated osteoarticular infections: A multicentre retrospective study from Turkey
    (Oxford Univ Press, 2025) Guler, Ozlem; Uzel, Murat; Tepe, Dilsat; Aksoy, Firdevs; Cinar, Gule; Memikoglu, Kemal Osman; Durdu, Bulent
    This multicentre retrospective study investigated the epidemiology, clinical characteristics, and fluconazole resistance rates of Candida species in osteoarticular infections across Turkey as well as the factors influencing complete recovery. Data were gathered from 73 adult patients diagnosed with proven or probable Candida-associated osteoarticular infections between 2015 and 2025 from 20 healthcare centres. The most common clinical presentation was spondylodiscitis, followed by the involvement of phalangeal bones in the hands and feet. Non-albicansCandida species accounted for 37/73 cases (50.7%), with Candida parapsilosis being the most frequent. Fluconazole resistance was low among C. albicans isolates (3%) but higher among non-albicans yeasts (27%). Bacterial co-infection, predominantly Gram-positive bacteria, was detected in 52.1% of cases. Diabetes was present in 50/73 patients (68.5%), particularly insulin-dependent diabetes, and was a prominent comorbidity that may have also contributed as a predisposing factor. Radiological detection of osteomyelitis was achieved in 69.9% of patients. Fluconazole was the most commonly used antifungal agent (74%) with a median treatment duration of 90 days. Multivariate analysis revealed that surgical debridement was significantly associated with a higher odds of clinical recovery (adjusted odds ratio [aOR], 5.764; 95% confidence interval [CI], 1.360-24.434; P = .017), whereas diabetes mellitus was significantly associated with a lower odds of total recovery (aOR, 0.205; 95% CI, 0.053-0.792; P = .022). In conclusion, this multicentre study provides epidemiological data and fluconazole resistance rates of Candida species causing osteoarticular infections in Turkey, highlights the occurrence of C. auris in this cohort, and identifies surgical intervention and diabetes mellitus as factors significantly associated with recovery. This study analysed bone and joint infections with the yeast Candida from multiple Turkish hospitals over 10 years. Non-Candida albicans species were the most common (50.7%). The spine bones and discs were mostly affected. Diabetes was a key risk factor. Treatment generally lasted around 90 days.
