[PMID: 32739457 DOI: 10.1016/j.exphem.2020.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Revised: 07/06/2020] [Accepted: 07/26/2020] [Indexed: 10/23/2022]
Abstract
In the elderly with cytopenia, the diagnosis of myelodysplastic syndrome (MDS) may be missed. Cytokine levels contribute to the pathology of MDS. Hence, the objectives were to evaluate cytogenetic profile as a prognostic indicator in risk stratification and cytokine levels as a screening tool in patients with cytopenia for diagnosis. Over 2 years (2016-2018), 150 elderly patients were screened. MDS diagnosis was confirmed by morphology. Interleukin-2 (IL-2) and IL-6 levels were assessed in 50 patients, and karyotyping was performed in 20 confirmed cases of MDS. Age-matched healthy controls were used for comparison of cytokine levels. Among 150 patients, 88.6% had anemia, including nutritional anemia (51.2%). MDS diagnosis was confirmed in 35 patients. In 15 patients, unexplained cytopenia (UC) was present. Karyotyping in 20 MDS patients was normal in 15 (75%) patients and revealed a complex karyotype in four (20%) patients and double chromosomal abnormality in one (5%) patient. The Revised International Prognostic Scoring System (IPSS-R) scored 91% in the low-risk group and 9% (n = 3) in the high-risk group; the latter three developed acute myeloid leukemia (AML) and two of them had a 7q deletion. Among the 15 cases of UC, one patient died from refractory anemia. No significant difference in levels of IL-2 and IL-6 were found between MDS and UC patients when compared with healthy controls, as well as between different risk groups and karyotypes. A significant difference in IL-2 levels was found in MDS patients with disease progression and with stable disease. On the basis of the findings, it is suggested that IL-2 levels will help in predicting disease progression.

Serum-soluble interleukin-2 receptor (sIL-2R) is an extremely strong prognostic factor for patients with peripheral T-cell lymphoma, unspecified (PTCL-U). J Cancer Res Clin Oncol 2008; 135:53-9.

Abstract
PURPOSE The aim of this study was to assess the prognostic factors of peripheral T-cell lymphoma, unspecified (PTCL-U). PATIENTS AND METHODS We retrospectively analyzed 30 cases fulfilling the criteria of PTCL-U defined by the World Health Organization classification. The patients were treated with 6-8 cycles of a CHOP or THP (pirarubicin)-COP regimen. RESULTS A high serum sIL-2R level (> or =2,000 U/ml) at onset was associated with a low complete remission rate. Patients with high sIL-2R had significantly lower survival rates (5 year, 15.1%) than those with low sIL-2R (<2,000 U/ml) (100%) (P < 0.005). Factors associated with worse overall survival in a univariate analysis were high sIL-2R (P < 0.005), high age (>60 years) (P < 0.05), poor performance status (P < 0.01) and poor international prognostic index (P < 0.05). No correlation was observed between sIL-2R and other markers. Multivariate analysis showed that only sIL-2R was a prognostic factor for overall survival (P < 0.01). CONCLUSION The results suggest that a high serum sIL-2R level predicts a poor prognosis in PTCL-U.

Abstract
The mechanism of T cell lymphopenia in myelodysplastic syndromes (MDS) is unknown. We investigated apoptosis in freshly isolated and cultured lymphocytes; the latter were used to detect cells not yet apoptotic but destined for apoptosis. Apoptosis increased in both fresh and cultured T cells in MDS compared with those from healthy controls. Furthermore, in lymphopenic MDS patients the lymphocyte count correlated negatively with the degree of T cell apoptosis. MDS T cells showed increased Fas expression. However, in MDS but not in controls, the degree of T cell apoptosis was independent of the Fas expression level, and exogenous anti-Fas antibodies did not modulate T cell apoptosis. Mechanisms other than the Fas-Fas ligand pathway may induce T cell apoptosis in MDS.

Abstract
Myelodysplastic syndromes (MDS) are common malignant disorders with a poor prognosis. MDS are a group of highly heterogeneous disorders but show certain universal findings including a high incidence in the elderly population, cytopenia, dysplastic myeloid cells, and frequent transformation to acute myeloid leukemia. Until recently, the vast majority of MDS patients were treated with supportive therapy alone, such as transfusions. Allogeneic stem cell transplantation (SCT) has the potential for cure, although due to the age and comorbidity of MDS patients, the role of allogeneic SCT in MDS has been limited. Recently, research in MDS has shown substantial advances that have deepened our understanding of MDS pathophysiology and changed our approach to MDS patients. This review touches on some recent developments in the diagnosis and pathophysiology of MDS.

Abstract
PURPOSE The aim of the present study was to assess the prognostic significance of serum soluble interleukin-2 receptor (sIL-2R) in aggressive non-Hodgkin's lymphoma (NHL). METHODS One hundred and thirteen consecutive patients with previously untreated aggressive NHL (diffuse large B-cell lymphoma, 96; peripheral T-cell lymphoma, 17) prospectively participated in this study between 1995 and 2001. The patients were treated with 6-8 cycles of a CHOP or THP (pirarubicin)-COP regimen. RESULTS A high serum sIL-2R level (2,000 U/ml and over) at onset was associated with a low complete remission rate. Patients with high sIL-2R had significantly lower survival rates (5-year, 24%) than those with low sIL-2R (under 2,000 U/ml) (74%) (P<0.01). Multivariate analysis employing sIL-2R levels and conventional prognostic factors demonstrated that high sIL-2R, presence of B-symptoms, and advanced age (60 years and older) were significantly unfavorable variables for overall survival. In addition, we attempted to use sIL-2R in combination with the International Prognostic Index (IPI). The patients in the high (H) risk group and those with high sIL-2R in the low-intermediate (LI)/high-intermediate (HI) risk group had significantly lower survival rates than the patients in the low (L) risk group and those with low sIL-2R in the LI/HI risk group (P<0.001). CONCLUSION The results suggest that a high serum sIL-2R level predicts a poor prognosis in aggressive NHL and may be a useful biomarker for selecting appropriate treatment when used in combination with the IPI.

Abstract
Myelodysplastic syndrome (MDS) consists of a heterogeneous group of acquired hematopoietic stem cell disorders, characterized by bone marrow failure and leukemic transformation. Since hematological manifestations and clinical outcomes vary widely among MDS patients, a considerable number of studies have tried to identify the prognostic parameters for the stratification of patients into different risk groups. Based on reported risk-based studies, the International Prognostic Scoring System (IPSS) was proposed as a reliable risk assessment method for primary MDS patients, and several validating studies have clarified its usefulness. Critical prognostic parameters of the IPSS consist of chromosome findings, the percentage of marrow blasts, and the number of peripheral blood cytopenias. Although other laboratory findings, including several molecular alterations, have been identified as convincing prognostic factors in MDS, these molecular configurations were not selected as prognostic parameters in the IPSS, because analysis for these alterations were not routinely available for the management of patients with MDS. Because recent advances in molecular genetics may make it available as a routine work-up of MDS in the future, we discuss potential improvement of the IPSS by the addition of molecular analysis to the system, with particular reference to the configuration of the TP53 gene.

Abstract
Angiogenesis plays a key role in a broad array of physiologic and pathologic processes. Two major systems--coagulation and fibrinolysis--maintaining hemostasis, have recently been implicated in angiogenesis. Generation of mice deficient in components of coagulation and plasminogen systems has provided an extraordinary opportunity to define the role of each of these systems in vivo and to elucidate molecular mechanisms involved in angiogenesis. It appears that several factors of the coagulation system, such as the tissue factor, the factor V and the thrombin receptor, play an important role in embryonic vessel formation, most probably in the formation of the primitive vascular wall. In addition, the plasminogen system appears to play a significant role in angiogenesis in adulthood, regulating the migration of endothelial and smooth muscle cells, the degradation of the extracellular matrix and activity of the metalloproteinase system. These new revelations open a possibility for future therapeutic strategies to specifically control angiogenesis in different pathological processes where abnormalities of tissue vascularization are pathogenetically prominent.

Abstract
We examined the plasma soluble interleukin-2 receptor (sIL-2R) level in 80 subjects with myelodysplastic syndromes (MDS) and analyzed its correlation with hematologic/immunologic parameters and the subsequent clinical course. Compared with low-risk MDS (refractory anemia (RA) and RA with ringed sideroblasts) and normal individuals, the plasma sIL-2R level was significantly elevated in high-risk MDS (three other MDS subtypes and acute leukemia following MDS) patients. There was a significant negative correlation between the plasma sIL-2R level and the absolute counts of T and natural killer cells. Furthermore, the plasma sIL-2R level showed a significant positive correlation with the total cell mass and blast mass in particular, in the marrow, but not with the absolute count of IL-2Ralpha-chain-positive lymphocytes in the circulation. Fourteen of our 40 low-risk MDS subjects developed at least one of the following events during the follow-up period: erythrocyte transfusion dependence, infections requiring hospitalization, disease progression or MDS-related death. The plasma sIL-2R level was significantly higher in these patients than in event-free low-risk cases. By logistic regression analysis of various parameters in the 40 low-risk subjects, the plasma sIL-2R level was identified as a valuable independent parameter for predicting the development of events. Based on these findings, we hypothesize that the sIL-2R plays a role in the development of morbidity and mortality in MDS by inducing immunologic dysfunction.

Abstract
Promising results in children with myelodysplastic syndromes (MDS) have been reported with high-dose methylprednisolone (HDMP) as a differentiation inducer, combined with cytotoxic chemotherapy. HDMP treatment has been shown to stimulate some cytokines in patients with acute leukemia. In the present study the effect of HDMP treatment on serum levels of interleukin 2 (IL-2) was evaluated in five children with MDS. Remarkable increases in serum IL-2 levels were observed 3 and 7 days after HDMP (30 mg/kg per day) treatment in three patients with chronic myelomonocytic leukemia (CMML). There was no correlation between the peripheral blood absolute lymphocyte counts and serum IL-2 levels. The results of this preliminary study indicate that the use of short-course HDMP treatment might be beneficial to increase the serum IL-2 level in patients with CMML.
