Osteoarticular cryptococcosis successfully treated with high-dose liposomal amphotericin B followed by oral fluconazole

Background: Skeletal involvement of Cryptococcus neoformans is infrequent and usually associated with disseminated cryptococcosis or underlying predisposing conditions. We present an atypical case of osteoarticular cryptococcosis in an immunocompetent patient. Case presentation: We herein report a case of bone and soft tissue cryptococcal infection in a 42-year-old male from Pakistan with well-controlled diabetes without other associated immunodeficiencies treated with antifungal therapy without surgical debridement. Furthermore, the patient developed toxidermia due to fluconazole use, so a fluconazole desensitization was performed. Therapeutic management also included the performance of therapeutic drug monitoring of fluconazole plasma concentrations. Conclusion: To our knowledge, this is the first case of osteoarticular cryptococcosis treated with this treatment regimen. This strategy may be of interest to try to reduce hospital stay and associated complications

Comparative analysis of complicated urinary tract infections caused by extensively drug-resistant pseudomonas aeruginosa and extended-spectrum β-lactamase-producing klebsiella pneumoniae

The objective was to compare clinical characteristics, outcomes, and economic differences in complicated urinary tract infections (cUTI) caused by extensively drug-resistant Pseudomonas aeruginosa (XDR P. aeruginosa) and extended-spectrum beta-lactamase-producing Klebsiella pneumoniae (ESBL-K. pneumoniae). A retrospective study was conducted at a tertiary care hospital. Patients with XDR P. aeruginosa and ESBL-K. pneumoniae cUTIs were compared. The primary outcome was clinical failure at day 7 and at the end of treatment (EOT). Secondary outcomes: 30- and 90-day mortality, microbiological eradication, and economic cost. Two-hundred and one episodes were included, of which 24.8% were bloodstream infections. Patients with XDR P. aeruginosa cUTI more frequently received inappropriate empirical therapy (p < 0.001). Nephrotoxicity due to antibiotics was only observed in the XDR P. aeruginosa group (26.7%). ESBL-K. pneumoniae cUTI was associated with worse eradication rates, higher recurrence, and higher infection-related readmission. In multivariate analysis, XDR P. aeruginosa was independently associated with clinical failure on day 7 of treatment (OR 4.34, 95% CI 1.71-11.04) but not at EOT, or with mortality. Regarding hospital resource consumption, no significant differences were observed between groups. XDR P. aeruginosa cUTI was associated with worse early clinical cures and more antibiotic side effects than ESBL-K. pneumoniae infections. However, no differences in mortality or in hospitalization costs were observed

Comparison of hospitalized COVID-19 and influenza patients requiring supplemental oxygen in a cohort study: clinical impact and resource consumption

Data de publicació electrònica: 20-04-2022Background: To compare clinical characteristics, outcomes, and resource consumption of patients with COVID-19 and seasonal influenza requiring supplemental oxygen. Methods: Retrospective cohort study conducted at a tertiary-care hospital. Patients admitted due to seasonal influenza between 2017 and 2019, or with COVID-19 between March and May 2020 requiring supplemental oxygen were compared. Primary outcome: 30-day mortality. Secondary outcomes: 90-day mortality and hospitalization costs. Attempted sample size to detect an 11% difference in mortality was 187 patients per group. Results: COVID-19 cases were younger (median years, 67 (IQR 54-78) vs 76 (IQR 64-83); p < 0.001) and more frequently overweight whereas influenza cases had more hypertension, immunosuppression, and chronic heart, respiratory and renal disease. Compared to influenza, COVID-19 cases had more pneumonia (98% vs 60%, <0.001), higher MEWS and CURB-65 scores and were more likely to show worse progression on the WHO ordinal scale (33% vs 4%; p < 0.001). The 30-day mortality rate was higher for COVID-19 than for influenza: 15% vs 5% (p = 0.001). The median age of non-surviving cases was 81 (IQR 74-88) and 77.5 (IQR 65-84) (p = 0.385), respectively. COVID-19 was independently associated with 30-day (HR 4.6, 95%CI, 2-10.4) and 90-day (HR 5.2, 95%CI, 2.4-11.4) mortality. Sensitivity and subgroup analyses, including a subgroup considering only patients with pneumonia, did not show different trends. Regarding resource consumption, COVID-19 patients had longer hospital stays and higher critical care, pharmacy, and complementary test costs. Conclusions: Although influenza patients were older and had more comorbidities, COVID-19 cases requiring supplemental oxygen on admission had worse clinical and economic outcomes
