Changes in the hemostatic system during COVID infection lead to hypercoagulability. Numerous studies have evaluated hemostatic abnormalities in COVID patients during acute infection, in the period of hospitalization. However, the hemostatic status following hospital discharge has not been sufficiently assessed. Considering the importance of FVIII and D-dimer levels as markers for the assessment of thrombosis, our study aimed to evaluate changes in these markers, as well as the influence of patient’s age and clinical presentation of COVID infection on those hemostatic markers in the post-COVID phase. This prospective study (July 2020 to December 2022) included 115 COVID patients, 68 (59%) with asymptomatic/mild and 47 (41%) with moderate/severe clinical presentation. Patient follow-up included laboratory evaluation of FVIII and D-dimer levels at 1, 3, and 6 months following the COVID infection. Three months after the COVID infection, elevated FVIII was recorded in 44% of younger versus 65% of older individuals, p ¼ 0.05, respectively, and 30 versus 57% (p ¼ 0.008) 6 months post–COVID infection. With a focus on clinical presentation, a higher number of patients with moderate/severe COVID had elevated FVIII activity, but a statistically significant difference was observed only for the 6 months (32% mild vs. 53% moderate/severe, p ¼ 0.041) post-infection time point. Following a COVID infection, an increase in FVIII activity suggests a continued hypercoagulable state in the post-COVID period and correlates with elevated D-dimer levels. This increase in FVIII is more pronounced in patients with moderate/severe clinical picture and those patients older than 50 years. © 2024. Thieme. All rights reserved.

The Follicular Lymphoma International Prognostic Index (FLIPI) is widely used in the identification of risk groups among follicular lymphoma (FL) patients. The aim of the present study was to evaluate the prognostic value of FLIPI combined with the Charlson comorbidity index (CCI) and histological grade of lymphoma. 224 newly diagnosed FL patients (median age 56 years) treated with immunochemotherapy were retrospectively analysed. Low FLIPI had 21.0 % of patients, intermediate 28.1 % and high 46.9 %. 50.9 % of patients had no comorbidities. Only 7.1 % of patients had a high CCI score (≥2), while 25.9 % of patients were histological grade 3. Parameters that influenced overall survival were evaluated using Cox regression analysis, in which CCI, FLIPI and histological grade (p < 0.05) retained prognostic significance. By combining these parameters, we have developed the FCG score, which incorporates FLIPI, CCI, and histological grade. This score defines three risk categories (low: 41.5 %; intermediate: 37.5 %; high: 13.4 %), associated with significantly different survival (p < 0.0001); this consequently improves discriminative power by 9.1 % compared to FLIPI. FCG score represents a possible new prognostic index, highlighting the role of the patient’s clinical state and the histological characteristics of disease, as indicated by comorbidity index and histological grade of lymphoma. © 2016, The Japanese Society of Hematology.

The prognostic value of the International Prognostic Index (IPI) has been re-evaluated in the rituximab-treated diffuse large B cell lymphoma (DLBCL) patients. Accordingly, National Comprehensive Cancer Network-IPI (NCCN-IPI) has been introduced to estimate prognosis of DLBCL patients. However, comorbidities that frequently affect elderly DLBCL patients were not analyzed. The aim of this study was to evaluate the prognostic significance of comorbidities using Charlson Comorbidity Index (CCI) in 962 DLBCL patients. According to CCI, majority of patients (73.6%) did not have any comorbidity, while high CCI (≥ 2) was observed in 71/962 (7.4%) patients, and in 55/426 (12.9%) of the elderly patients aged ≥ 60 years. When the CCI was analyzed in a multivariate model along with the NCCN-IPI parameters, it stood out as a threefold independent risk factor of a lethal outcome. Also, we have developed a novel comorbidity-NCCN-IPI (cNCCN-IPI) by adding additional 3 points if the patient had a CCI ≥ 2. Four risk groups emerged with the following patient distribution in low, low-intermediate, high-intermediate, and high group: 3.4, 34.3, 49.4, and 12.5%, respectively. The prognostic value of the new cNCCN-IPI was 2.1% improved compared to that of the IPI, and 1.3% improved compared to that of the NCCN-IPI (p < 0.05). This difference was more pronounced in elderly patients, in whom the cNCCN-IPI showed a 5.1% better discriminative power compared to that of the IPI, and 3.6% better compared to the NCCN-IPI. The NCCN-IPI enhanced by the CCI and combined with redistributed risk groups is better for differentiating risk categories in unselected DLBCL patients, especially in the elderly. © 2017, Springer-Verlag GmbH Germany, part of Springer Nature.

Within a personalized treatment approach in multiple myeloma (MM), the prognostic significance of cereblon (CRBN) expression was analyzed in 92 newly diagnosed patients. In patients treated with thalidomide-based combinations, CRBN expression significantly affected the treatment response (P = .028) and progression-free survival (P = .017). With implications for the treatment outcome, measurement of CRBN expression might represent an additional prognostic tool in a personalized treatment approach. Background To personalize the treatment approach for patients with multiple myeloma (MM), molecular markers such as cereblon (CRBN) are currently the focus of investigation. The aim of the present study was to test the prognostic significance of CRBN expression in MM patients ineligible for autologous stem cell transplantation (ASCT). Patients and Methods The data from 92 previously untreated patients were analyzed. The distribution according to the International Staging System score was 26.1%, 30.4%, and 43.5% with a score of 1, 2, and 3, respectively. Thalidomide- and bortezomib-based combinations were used in 83.7% and 16.3% of the patients, respectively. Results A treatment response (complete remission, very good partial remission, partial remission) was achieved in 83.7% of the patients and correlated with high CRBN expression (P = .006), mainly in the patients treated with thalidomide (P = .028). Low CRBN expression affected progression-free survival (PFS; P = .017) but not overall survival (OS) in patients treated with thalidomide and had no influence on OS in the bortezomib group. In the Cox regression model, low CRBN expression was the most important prognostic parameter that influenced PFS in the thalidomide-treated patients (P = .012). Conclusion CRBN expression is of prognostic value in MM patients ineligible for ASCT treated with thalidomide as an immunomodulatory drug. With low expression indicating a possible suboptimal treatment outcome, measurement of CRBN expression might serve as additional prognostic tool in the personalized treatment approach. © 2016 Elsevier Inc.

Prognostic significance of immune microenvironment has been emphasized using the most advanced analysis, with consecutive attempts to reveal prognostic impact of this findings. The aim of this study was to compare and define prognostic significance of clinical parameters, microvessel density (MVD) in tumour tissue and expression of CD44s as adhesive molecule on tumour cells in diffuse large B cell lymphoma-DLBCL, primary central nervous system DLBCL-CNS DLBCL and follicular lymphoma-FL. A total of 202 histopathological samples (115 DLBCL/65 FL/22 CNS DLBCL) were evaluated. Overall response (complete/partial remission) was achieved in 81.3 % DLBCL patients, 81.8 % primary CNS DLBCL and 92.3 % FL. Absolute lymphocyte count-ALC/Absolute monocyte count-AMC >2.6 in DLBCL and ALC/AMC ≥ 4.7 in FL were associated with better event-free survival (EFS) and overall survival (OS) (p < 0.05). In DLBCL, MVD > 42 blood vessels/0.36 mm2 correlated with primary resistant disease (p < 0.0001), poorer EFS and OS (p = 0.014). High CD44s expression in FL correlated with inferior EFS and OS (p < 0.01). In DLBCL, multivariate Cox regression analysis showed that ALC/AMC was independent parameter that affected OS (HR 3.27, 95 % CI 1.51–7.09, p = 0.003) along with the NCCN-IPI (HR 1.39, 95 % CI 1.08–1.79, p = 0.01). Furthermore, in FL, ALC/AMC mostly influenced OS (HR 5.21, 95 % CI 1.17–23.21, p = 0.03), followed with the FLIPI (HR 3.98, 95 % CI 1.06–14.95, p = 0.041). In DLBCL and FL, ALC/AMC is simple and robust tool that is, with current prognostic scores, able to define long-term survival and identify patients with inferior outcome. The introduction of immunochemotherapy might altered the prognostic significance of microenvionmental biomarkers (MVD and CD44s). © 2016, Arányi Lajos Foundation.
