RESUMO
BACKGROUND AND AIM: Viral pneumonia is the most relevant clinical presentation of COVID-19 which may lead to severe acute respiratory syndrome and even death. Eosinopenia was often noticed in patients with COVID-19 pneumonia, but its role is poorly investigated. The aim of the present study was to investigate the characteristics and clinical outcomes of patients with COVID-19 pneumonia and eosinopenia. METHODS: We revised the records of consecutive patients with COVID-19 pneumonia admitted to our ER-COVID-19 area in order to compare clinical characteristics and outcomes of patients with and without eosinopenia. We considered the following clinical outcomes: 4-weeks survival; need for intensive respiratory support; and hospital discharge. RESULTS: Out of first 107 consecutive patients with pneumonia and a positive COVID-19 nasopharyngeal swab, 75 patients showed undetectable eosinophil count (absolute eosinopenia). At 4 weeks, 38 patients (38.4%) had required intensive respiratory treatment, 25 (23.4%) deceased and 42 (39.2%) were discharged. Compared with patients without absolute eosinopenia, patients with absolute eosinopenia showed higher need of intensive respiratory treatment (49.3% vs 13.3%, P < .001), higher mortality (30.6% vs 6.2%, P .006) and lower rate of hospital discharge (28% vs 65.6%, P < .001). Binary logistic regression analyses including neutrophil, lymphocyte, eosinophil, basophil and monocyte counts showed that absolute eosinopenia was an independent factor associated with 4-weeks mortality, need for intensive respiratory support and hospital discharge. CONCLUSIONS: Absolute eosinopenia is associated with clinical outcomes in patients with COVID-19 pneumonia and might be used as a marker to discriminate patients with unfavourable prognosis.

RESUMO
BACKGROUND: Premenopausal patients with breast cancer and more than 10 positive axillary nodes (BC>10) have a poor prognosis: In these patients the best adjuvant therapy (CT) has not yet been established. PATIENTS AND METHODS: Forty-two BC>10 received, in sequence, the following adjuvant treatments: luteinizing hormone releasing hormone (LH-RH) analog for 5 years; anthracycline-based induction chemotherapy; radiation therapy; platinum-based high-dose CT, with autologous bone marrow transplantation; immunotherapy with interleukin 2 (IL2) and 13-cis retinoic acid (RA); anastrazole given 5 years to estrogen receptor-positive patients. Primary endpoints of the study were disease-free survival (DFS) and overall (OS) survival. A secondary endpoint was toxicity. RESULTS: The median age of patients was 41 years, and the mean number of positive axillary nodes was 14. Estrogen and progesterone receptors were positive in 57% and 29% of patients respectively, while 14% of patients had triple-negative disease. With a median follow-up of 120 months for patients remaining alive at the end of study, median DFS and OS, had not yet been reached. The 20-year DFS and OS rates were 63.8%, and 81.6%, respectively. One to two years after the end of the therapy, three patients had had four full-term pregnancies. CONCLUSION: Treatment with LH-RH analog, high-dose CT, peripheral blood progenitor cells and IL2 with RA for patients with BC>10 is feasible, has moderate toxicity, while preserving ovarian function, seems to improve the expected DFS and OS for these high-risk patients.

Interleukin-2 (IL-2) targets cells bearing IL-2 receptors and induces different degrees of lymphocytosis. This study retrospectively evaluated whether lymphocytosis, in addition to clinical characteristics at baseline and to tumor objective response, may predict overall survival in metastatic renal cell carcinoma patients who received IL-2 subcutaneously (s.c.). Overall survival, clinical characteristics, tumor response, and total lymphocyte count at baseline and during the first treatment cycle of 266 advanced renal cell cancer patients, treated with 1 of 4 different first-line s.c. IL-2-based protocols, were studied using the Cox multivariate analysis. Median IL-2 cumulative dose and length of treatment (+/-SD) were 232 +/- 282 x 10(6)/m(2) in 7 +/- 5.9 weeks, respectively. Median overall survival (os) was 13.1 months (range 0.7-86.9+) in all. Tumor outcome consisted of: 9 CR (3%) (os = NR); 35 PR (13%) (os = 19.7 months.); 117 SD (44%) (os = 15.1 months); 105 PD (39%) (os = 6.4 months). Median lymphocyte counts were 1400/mm(3) at baseline (25th-75th, 900-1900/mm(3)) and 3600/mm(3) as a maximum value (25th-75th, 2600-4800/mm(3)). Death risk significantly decreased by 11% for each 1,000 lymphocytes/mm(3) (RR 0.89; 95% CI 0.82-0.97), after correcting for clinical characteristics (PS ECOG 0 versus > or =1, time from primary diagnosis > or =2 years versus <2 years, number of metastatic sites 1 versus >1) and tumor response (CR, PR). A two-step bootstrapping procedure confirmed such predictive performance. Lymphocyte count monitoring represents a biomarker of the host response to subcutaneous IL-2 treatment useful for multimodal clinical assessment, as it predicts overall survival in advanced cancer patients independently from tumor response and from main clinical characteristics.
