RESUMO
The emergence of SARS-CoV-2 Omicron variant has led to a complete reconfiguration of the therapeutic landscape, with all monoclonal antibodies having lost any neutralization activity. We report here a case series of 75 immunocompromised patients infected by the Omicron variant who benefited from COVID-19 convalescent plasma (CCP). At Day 28, the overall survival was 76% (95% CI 67-86) with no significant difference in the clinical outcome between patients with hematological malignancies, solid organ transplantation or autoimmune diseases. No safety concern was reported during the course of the study. These results showed that CCP is well tolerated and represents a treatment option for immunocompromised patients who remain highly impacted by the COVID19 epidemic.

PURPOSE: Analyze the diagnostic performance of suction drainage fluid culture for acute surgical site infection, which has not been specifically reported in spine surgery patients. METHOD: This was a retrospective single-center observational study including data from 363 patients who underwent aseptic instrumented spine surgery between 2015 and 2017. A suction drain was inserted in all cases. Data analyzed were patient age, gender, ASA score, indication for surgery (degenerative disease, tumor, trauma), spine level (cervical, thoracic, lumbar), procedure performed and spine level, operative time, body temperature, postoperative C-reactive protein time-curve, clinical aspect of surgical scar, bacteriology results of suction drainage fluid, and in case of revision surgery, lavage fluid. Major criteria for periprosthetic infection proposed by the Musculoskeletal Infection Society (MSIS) were accepted as the gold standard for the diagnosis of acute surgical site infection. RESULTS: The overall rate of surgical site infection was 6.9% (5.76% for 1- or 2-level fusion, 5.81% for 3- or 4-level fusion, and 15.6% for 5-level fusion and above). The suction drain was withdrawn on the second postoperative day in 44.1% of cases and the third day in 39.1%. The sensitivity of suction drainage fluid culture for the diagnosis of surgical site infection was 20% [95%CI 6.8-40.7%] with a 96.2% [95%CI 93.2-97.9] specificity. CONCLUSION: The diagnostic performance of suction drainage fluid culture after aseptic instrumented spine surgery for acute surgical site infection is insufficient to warrant its use in routine practice.

We report the first case of extended-spectrum beta-lactamase producing E. coli community-acquired meningitis complicated with multiple aortic mycotic aneurysms. Because of the acute aneurysm expansion with possible impending rupture on 2 abdominal CT scan, the patient underwent prompt vascular surgery and broad spectrum antibiotic therapy but he died of a hemorrhagic shock. Extended-spectrum beta-lactamase producing E. coli was identified from both blood and cerebrospinal fluid culture before vascular treatment. The present case report does not however change the guidelines of Gram negative bacteria meningitis in adults.
