There is no consensus on the management of coronavirus disease 2019 (COVID‐19) and modification of immunosuppressive therapy in kidney transplant recipients (KTRs). In this study, we examined the clinical outcome of our KTRs with COVID‐19 disease, who were treated with a broad‐spectrum anti‐inflammatory protocol. This protocol is essentially composed of intravenous immunoglobulin +/‐ tocilizumab in KTRs with severe COVID‐19 pneumonia. Among 809 KTRs, 64 patients diagnosed with COVID‐19 disease between April 2020 and February 2021, were evaluated. Twenty‐nine patients with pneumonia confirmed by chest computed tomography (CCT) were hospitalized. The treatment protocol included high‐dose intravenous methylprednisolone, favipiravir, enoxaparin, and empirical antibiotics. Patients with pneumonic involvement of more than 25% on CCT with or without respiratory failure were given a total of 2 g/kg intravenous immunoglobulin (IVIg) therapy. Nonresponders received tocilizumab, an interleukin‐6 receptor antibody. Of the 29 patients with pneumonia, 6 were treated in other hospitals. These six patients did not receive IVIg and 5 of them deceased. In our center, IVIg treatment was applied to 15 of 23 patients. Seven of them required tocilizumab. Respiratory parameters improved significantly in all but one patient after IVIg ± tocilizumab treatment. The mortality rate was 6.6% in patients who received IVIg therapy and 35.7% in those who did not ( p = 0.08). The mortality rate was higher in patients who received treatment in external centers (2.2% vs. 26.3%; p = 0.0073). The treatment of KTRs with severe COVID‐19 pneumonia in organ transplant centers with significant experience yields better results. The administration of broad‐spectrum anti‐inflammatory treatment in this patient group was safe and provided excellent outcomes.

In this study, we planned to investigate the clinical course of patients with breast cancer with oligometastatic bone disease (OMBD). The patients were grouped according to the characteristics and the sites of metastases. Group I included 928 patients without metastasis. Group II, the OMBD group, included 68 patients. Group III, the widespread metastasis group, comprised 185 patients with multiple bone metastases and/or solid organ metastases. The mean overall survival of the groups was 16.7 ± 0.3 years in group 1, and 7.8 ± 0.8 and 5.9 ± 0.4 years in groups 2 and 3, respectively (p < 0.001 for the comparison of all three groups together; p < 0.001 for group 1 vs. 2 and 3) and (p = 0.037 for group 2 vs. group 3). In the subgroup survival analysis of patients in group 2 (OMBD), the mean and median survival was 5.5 ± 0.8 and 4.0 ± 0.8 years vs. 9.2 ± 0.98 and 9.0 ± 1.05 years in patients with more than one bone metastasis and single bone metastasis, respectively (p = 0.019). OMBD seems to be a different disease than breast cancer with isolated bone metastases. The high risk of developing OMBD, especially following locoregional recurrence, increases the importance of locoregional therapy in large T and N stage tumors.
