Prognostic factors and combined use of tocilizumab and corticosteroids in a Spanish cohort of elderly COVID-19 patients.

Coronavirus disease 2019 (COVID-19) infection in elderly patients is more aggressive and treatments have shown limited efficacy. Our objective is to describe the clinical course and to analyze the prognostic factors associated with a higher risk of mortality of a cohort of patients older than 80 years. In addition, we assess the efficacy of immunosuppressive treatments in this population. We analyzed the data from 163 patients older than 80 years admitted to our institution for COVID-19, during March and April 2020. A Lasso regression model and subsequent multivariate Cox regression were performed to select variables predictive of death. We evaluated the efficacy of immunomodulatory therapy in three cohorts using adjusted survival analysis. The mortality rate was 43%. The mean age was 85.2 years. The disease was considered severe in 76.1% of the cases. Lasso regression and multivariate Cox regression indicated that factors correlated with hospital mortality were: age (hazard ratio [HR] 1.12, 95% confidence interval [CI]: 1.03-1.22), alcohol consumption (HR 3.15, 95% CI: 1.27-7.84), CRP > 10 mg/dL (HR 2.67, 95% CI: 1.36-5.24), and oxygen support with Venturi Mask (HR 6.37, 95% CI: 2.18-18.62) or reservoir (HR 7.87, 95% CI: 3.37-18.38). Previous treatment with antiplatelets was the only protective factor (HR 0.47, 95% CI: 0.23-0.96). In the adjusted treatment efficacy analysis, we found benefit in the combined use of tocilizumab (TCZ) and corticosteroids (CS) (HR 0.09, 95% CI: 0.01-0.74) compared to standard treatment, with no benefit of CS alone (HR 0.95, 95% CI: 0.53-1.71). Hospitalized elderly patients suffer from a severe and often fatal form of COVID-19 disease. In this regard, several parameters might identify high-risk patients upon admission. Combined use of TCZ and CS could improve survival.

Orthopedic Surgical Treatment and Perioperative Complications in Multiple Myeloma Bone Disease: Analysis of a Series (2009-2018).

BACKGROUND: More than 90% of patients with multiple myeloma (MM) develop lytic bone lesions that can be surgically treated for symptomatic relief and functional improvement. METHODS: This was a retrospective observational analytic study conducted between 2009 and 2018, including 58 patients with MM bone disease who underwent 77 orthopedic surgical procedures and were co-managed by internal medicine. Analysis of data related to MM bone disease, different modalities of surgical treatment, perioperative complications, and survival was performed. RESULTS: Median age was 72 years (66.5-77 years) and 56.9% of patients were males; 54.43% of injuries were located in the spine, 27.85% in the pelvis or lower limbs, 15.19% in the upper limbs, and 75.32% of patients had pathologic fractures. In 29.31% of the cases, the bone lesion was the debut of MM. Surgical procedures performed were mainly kyphoplasty (48.05%) and intramedullary nailing (29.87%). The overall complication rate following surgery was 74.03%. Only 20.78% of cases had a surgical complication. Among medical complications, we registered 28.57% transfusion requirements, 25.97% acute renal failures, 24.68% developed an infection, and 10.39% developed hypercalcemia. Patients were followed-up for a mean of 6.13 years and 37.93% suffered a new fracture. The median overall survival time for patients after surgery was 32.9 months (11.6-49). The estimated overall survival at 1, 3, and 5 years after surgery was 81.17%, 57%, and 34.11%, respectively. CONCLUSIONS: The orthopedic surgical treatment of MM bone disease aims to improve symptomatology and patient quality of life; however, these patients have a high risk of perioperative complications and considerable early mortality, making multidisciplinary management with medical specialties essential.
