Increase in Ischemia-Modified Albumin and Pregnancy-Associated Plasma Protein-A in COVID-19 Patients

This study was undertaken due to the urgent need to explore reliable biomarkers for early SARS-CoV-2 infection. We performed a retrospective study analyzing the serum levels of the cardiovascular biomarkers IL-6, TNF-α, N-terminal pro-B natriuretic peptide, cardiac troponin T (cTnT), ischemia-modified albumin (IMA) and pregnancy-associated plasma protein-A (PAPP-A) in 84 patients with COVID-19.Patients were divided into three groups according to their RT-qPCR and IgG values: acute infection (n = 35), early infection (n = 25) or control subjects (n = 24). Levels of biomarkers were analyzed in patient serum samples using commercially available ELISA kits. Results showed a significant increase in IMA and PAPP-A levels in the early infected patients. Moreover, multivariate analysis and receiver operating characteristic (ROC) curve showed that IMA and PAPP-A had excellent discrimination value for the early stage of COVID-19. For IMA, the area under the ROC curve (AUC) had a value of 0.94 (95% confidence interval (CI): 0.881–0.999). Likewise, the serum level of PAPP-A was significantly higher in patients with early infection than in the control subjects (AUC = 0.801 (95% CI: 0.673–0.929)). The combined use of IMA and PAPP-A enhanced the sensitivity for total SARS-CoV-2-infected patients to 93%. These results suggest that the increased levels of PAPP-A and IMA shed light on underlying mechanisms of COVID-19 physiopathology and might be used as efficient biomarkers with high sensitivity and specificity for the early stage of COVID-19. Importantly, when monitoring pregnancy and cardiovascular diseases using PAPP-A or IMA levels, a SARS-CoV-2 infection should be discarded for proper interpretation of the results

Bicalutamide (Casodex) 150 mg as immediate therapy in patients with localized or locally advanced prostate cancer significantly reduces the risk of disease progression

Objectives. To investigate the efficacy and tolerability of bicalutamide (Casodex) as immediate therapy, either alone or as adjuvant to treatment of curative intent, in patients with localized or locally advanced (T1b-T4, any nodal status, M0) prostate cancer. Methods. This was a multicenter, prospective, randomized, double-blind, placebo-controlled trial in Europe, South Africa, Australia, and Mexico and is part of the Casodex Early Prostate Cancer program. Results. A total of 3603 men were randomized to receive bicalutamide (n = 1798) or placebo (n = 1805). The patient demographics were well balanced between the two groups. Prior therapy of curative intent had been given to 64% of the patients (prostatectomy [44%], radiotherapy [18%], and prostatectomy and radiotherapy [2%]) and 36% had been monitored with watchful waiting. After a median follow-up of 2.6 years and a median exposure to the study drug of 2.2 years, a significant 43% reduction in the risk of objective progression was observed for the bicalutamide group compared with the placebo group (hazard ratio 0.57, 95% confidence interval 0.48 to 0.69, P ≪0.0001). The time to prostate-specific antigen doubling was significantly delayed for the bicalutamide group compared with the placebo group (hazard ratio 0.37, 95% confidence interval 0.32 to 0.43, P ≪0.001). The survival data were immature, with 7.2% overall mortality. The most frequently reported adverse events with bicalutamide were gynecomastia alone (17.4%), breast pain alone (17.6%), and gynecomastia with breast pain (47.5%). Conclusions. Bicalutamide 150 mg daily as immediate therapy, alone or as adjuvant to treatment of curative intent, significantly reduced the risk of disease progression in patients with localized or locally advanced prostate cancer. Longer follow-up is underway to assess any benefit in overall survival. © 2001, Elsevier Science Inc.Articl

Bicalutamide (Casodex) 150 mg plus standard care in early non-metastatic prostate cancer: Results from Early Prostate Cancer Trial 24 at a median 7 years' follow-up

Trial 24, one of three ongoing trials in the Early Prostate Cancer programme, is evaluating the efficacy and tolerability of bicalutamide (Casodex) 150 mg following standard care (radiotherapy, radical prostatectomy or watchful waiting) in patients with early, non-metastatic prostate cancer. At 7 years' median follow-up, addition of bicalutamide significantly improved objective progression-free survival (PFS) for patients with locally advanced disease, reducing the risk of progression by 34% versus standard care alone (hazard ratio 0.66; 95% confidence interval 0.55, 0.79; P<0.001). In localized disease, a significant difference in objective PFS was not found. There was no significant difference in overall survival.Articl

Bicalutamide ('Casodex') 150mg in addition to standard care in patients with nonmetastatic prostate cancer: Updated results from a randomised double-blind phase III study (median follow-up 5.1y) in the early prostate cancer programme

Trial 24 is one of three placebo-controlled trials within the ongoing bicalutamide ('Casodex'+) Early Prostate Cancer (EPC) programme evaluating bicalutamide 150mg/day in addition to radical prostatectomy, radiotherapy or watchful waiting for T1b -4, any N, M0 prostate cancer. In Trial 24, at 5.1y median follow-up, the addition of bicalutamide significantly (P&lt;0.0001) improved objective progression-free survival (PFS) and prostate-specific antigen PFS compared with standard care alone. There was no significant difference in overall survival (P = 0.746). In the context of the whole EPC programme, long-term bicalutamide is not appropriate for localised disease, yet provides advantages in delaying disease progression in patients with locally advanced prostate cancer. © 2005 Nature Publishing Group.
