The unknown impact of multiple myeloma: assessing the impact of financial well-being on quality of life of caregivers.

PURPOSE: Patients with multiple myeloma and their caregivers are financially burdened, and their quality of life is significantly affected by treatment costs and care expenses. The aim of our study is to examine the impact of financial well-being of the caregiver on the life quality of patients with multiple myeloma. METHODS: The study included 113 patients with multiple myeloma and 113 caregivers in two hospitals located in Western Turkey. This study evaluated the demographic characteristics of patients and their caregivers, financial status, financial well-being, and quality of life of caregivers. Simple linear regression analyses were used to examine the impact of financial well-being on caregiver quality of life. RESULTS: The average age of multiple myeloma patients and caregivers is 64.00 ± 11.05 and 48.02 ± 11.4, respectively. Of patients, 50.4% and 62.8% of their caregivers were female. It is determined that 51.3% of the patients were diagnosed in 1-5 years, 85% received chemotherapy, and 80.5% had an ECOG performance status between 0 and 1. Caregivers' quality of life and financial well-being were found to be low. On one hand, while caregivers' financial well-being (ß = - 1.003; t = - 3.831; p = .000) negatively affected the quality of their lives, their financial satisfaction (ß = 2.507; t = 3.820; p = .000) positively affected the quality of their lives, on the other hand. CONCLUSIONS: Caregivers' quality of life declined as their financial well-being got worse. Decreased quality of life of caregivers may affect the quality of care they provide to patients with MM. Hence, this study recommends the following. First, nurses who care for patients with MM should always assess the financial situation of patients and caregivers. Second, patient navigators, hospital billing specialists, and social workers should provide financial guidance to multiple myeloma patients and caregivers and provide help in solving their financial problems. Finally, policies that support the financial situation of patients and caregivers should be developed.

Long-Term Efficacy of Erythropoiesis-Stimulating Agents in Patients with Low-Risk or Intermediate-1-Risk Myelodysplastic Syndrome: Multicenter Real-Life Data

Objective: This study was undertaken to evaluate the long-term clinical efficacy of epoetin alfa and darbepoetin alfa in patients with myelodysplastic syndrome (MDS) in a real-life setting. Materials and Methods: A total of 204 patients with low-risk or intermediate-1-risk MDS who received epoetin alfa or darbepoetin alfa were included. Hemoglobin levels and transfusion needs were recorded before treatment and at 12 months, 24 months, 36 months, and 48 months of treatment. Results: At the 36-month (p=0.025) and 48-month (p=0.022) visits, epoetin alfa yielded significantly higher hemoglobin levels compared to darbepoetin alfa. Transfusion needs were also significantly lower with epoetin alfa compared to darbepoetin alfa at 24 months (p=0.012) and in the low-risk group compared to the intermediate-risk group at 24 months (p=0.018), 36 months (p=0.025), and 48 months (p<0.001). Treatment response rates at the 24-month, 36-month, and 48-month visits in the epoetin alfa (43.0%, 33.6%, and 27.1%), darbepoetin alfa (29.9%, 22.7%, and 16.5%), low-risk (39.3%, 30.0%, and 26.0%), and intermediate-risk (29.6%, 24.1%, and 11.1%) groups were lower than those obtained at 12 months, and the values differed significantly for the 36-month and 48-month visits with values ranging from p<0.05 to p<0.001. Conclusion: This real-life long-term ESA extension study investigated the clinical efficacy of epoetin alfa and darbepoetin alfa for up to 48 months, revealing that treatment efficacy reached a plateau starting from the 24th month of therapy with a continuing decrease in treatment response rates regardless of treatment type, risk status, or gender. Nonetheless, significantly higher hemoglobin levels and marked improvement in transfusion needs were evident in epoetin-treated patients compared to darbepoetin-treated patients and in the low-risk group compared to the intermediate-risk group.

Polatuzumab vedotin, rituximab, and bendamustine combination in relapsed or refractory diffuse large B-cell lymphoma: a real-world data from Turkey.

Polatuzumab vedotin (Pola) with bendamustine and rituximab (BR) is a promising option for patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). We analyzed the data of 71 R/R DLBCL patients who had been treated with Pola-BR in the named patient program from March 2018 to April 2021 from 32 centers in Turkey. All patients received up to six cycles of Pola 1.8 mg/kg, rituximab 375 mg/m2 on day 1, and bendamustine 90 mg/m2 on days 1-2 of each cycle. Median age at Pola-BR initiation was 55 (19-84). The overall response rate was 47.9%, including 32.4% CR rate when a median of 3 cycles was applied. With a median follow-up of 5 months, the median OS was 5 months. Grade 3-4 neutropenia and thrombocytopenia were the most common hematological toxicities. The real-world data from our cohort showed the Pola-BR is an effective option with a manageable toxicity profile.

Use of nailfold video capillaroscopy in polycythemia vera.

Objectives: In this study, we aimed to investigate capillary vessel diameters and structural changes of capillaries by using nailfold video capillaroscopy (NVC) in patients with polycythemia vera (PV). Patients and methods: This cross-sectional study included a total of 24 patients (19 males, 5 females; mean age: 59.8±12.9 years; range, 50.2 to 68 years) who were diagnosed with PV and 15 healthy controls (11 males, 4 females; mean age: 40.7±5.1 years; range, 36 to 44 years) between June 2016 and February 2017. Nailfold video capillaroscopy was performed by an experienced rheumatologist who was blinded to clinical data. The apical, arterial, and venous limb diameters of capillaries were measured and microvascular changes of capillaries were scored. Results: When capillaries were evaluated in terms of morphological structures, giant capillary was detected in 67% of the patients with PV and 0% in the control group (p<0.05). The arterial, venous, and apical diameters of the capillaries were significantly higher in the patients with PV compared to the control group (p<0.001). Conclusion: The presence of giant capillaries and the marked increase of arterial, venous, and apical diameters of capillaries seem to be related to PV. As it additionally plays an important role in diagnosis, prognosis, and treatment monitoring of certain diseases, capillaroscopy can be considered to be a promising microcirculation biomarker.

The evaluation of patients with essential thrombocythemia in terms of risk of thrombosis.

OBJECTIVE: The aim of this study was to compare the incidence of factors associated with an increased risk of thrombosis in patients with essential thrombocythemia. METHODS: A total of 200 patients followed-up in our unit with a diagnosis of essential thrombocythemia in 13 years were analyzed retrospectively. RESULTS: Of the study participants, 60.5% were females and 39.5% were males, with an overall mean (±SD) age of 54.93 (±14.21) years. In 119 patients, Janus Kinase 2 was positive with 56.3% of cases. When two patient categories were defined as those with or without history of thrombosis, no significant differences were found in terms of Janus Kinase 2 positivity, mean age, as well as white blood cells and platelet counts (p>0.05). Also, no significant differences in thrombotic event incidence were found between patient categories defined on the basis of cut-off values for white blood cells (cut-off values of 15×103/mm3 and 8.7×103/mm3) and platelets (cut-off values of 1500×103/mm3) (p>0.05). CONCLUSION: Although our results are generally in line with the published data, some divergence from previous results has been observed with respect to risk factors for thrombotic events. Absence of a correlation between leukocytosis and thrombosis may be related with the significant decline in white blood cells after treatment. Also, a significant reduction in platelet counts occurring in association with treatment is linked with a lowered incidence of thrombosis. Janus Kinase 2-positive patients had a similar thrombosis frequency with that reported in the literature.

Conditioning Regimens for Relapsed/Refractory Lymphoma Patients Undergoing Autologous Stem Cell Transplantation: BEAM Versus High Dose ICE.

There are different drug combinations and conditioning regimens in lymphoma transplants. However, no randomized data is available to demonstrate the superiority of any regimen and the optimal choice is unknown. In this analysis, we compared the efficacy, toxicity and the survival outcomes of the BEAM and the high dose ICE (hdICE) conditioning regimens in relapsed NHL and relapsed/refractory Hodgkin Lymphoma patients undergoing auto-SCT. 83 patients with relapsed/refractory HL or relapsed NHL who were treated with Auto-SCT between 2006 and 2016, were analyzed retrospectively. 52 patients (62.7%) received BEAM, while 31 patients (37.3%) received hdICE. Between two groups there is no significant difference in age, gender, diagnosis, disease stage, chemosensitivity, ECOG performance status, time from diagnosis to transplant, salvage regimens and previous lines of chemotherapy. After a median of 59-month follow-up, PFS and OS rates of both groups were similar (5-year PFS was 51.6% in BEAM group, 48.8% in hdICE group, p = 0.71; 5-year OS was 58% in BEAM group, 54.8% in hdICE group, p = 0.93). The median neutrophil (11 vs. 10 days, p = 0.06) and platelet engraftment (13 vs. 11 days, p = 0.01) was faster and demand of transfusions were lesser in hdICE group (p = 0.03). However, severe renal toxicity was significantly higher in hdICE group in our study (p = 0.01). hdICE conditioning regimen may be used as an alternative to BEAM, with similar survival outcomes and toxicity profile, especially transplant centers that experience some difficulties in the availability of the carmustine.

Efficacy of convalescent plasma according to blood groups in COVID-19 patients

Background/aim: In this study, we aim to investigate the efficacy of convalescent plasma (CP) according to blood groups (BGs) in the treatment of critically ill patients diagnosed with COVID-19. Materials and methods: Twenty-eight critically ill and laboratory-confirmed COVID-19 patients who were admitted to the intensive care unit (ICU) of Sakarya University, Medical Faculty were included in the study. Patients were divided into 2 groups: patients who received anti-A antibody (Ab) containing CP (BG O and B) and those who did not receive CP containing anti-A Ab (BG A and AB). Results: Among the 28 patients, 13 patients received anti-A Ab containing CP (BG; B: 6, O: 7) and 15 patients did not receive anti-A Ab CP (BG; A: 13, AB: 2). Duration in ICU, the rates of mechanical ventilation (MV) support and vasopressor support, the case fatality rate, and the discharge rate were lower in patients who received CP containing anti-A Ab than not containing anti-A Ab CP. However, only the difference in the rate of MV support achieved statistically significance (P = 0.04) Conclusion: In our study, it was observed that the efficiency of CP without anti-A antibody was lower than that of plasma containing anti-A antibody, although it was not statistically significant. This result is thought to be due to the anti-A antibody's ability to block the ACE2 receptor. We believe that this hypothesis should be investigated in controlled studies with higher patient numbers.

Comparative evaluation of memory T cells in COVID-19 patients and the predictive role of CD4+CD8+ double positive T lymphocytes as a new marker.

BACKGROUND: The COVID-19 pandemic has affected the entire world, posing a serious threat to human health. T cells play a critical role in the cellular immune response against viral infections. We aimed to reveal the relationship between T cell subsets and disease severity. METHODS: 40 COVID-19 patients were randomly recruited in this cross-sectional study. All cases were confirmed by quantitative RT-PCR. Patients were divided into two equivalent groups, one severe and one nonsevere. Clinical, laboratory and flow cytometric data were obtained from both clinical groups and compared. RESULTS: Lymphocyte subsets, CD4+ and CD8+ T cells, memory CD4+ T cells, memory CD8+ T cells, naive CD4+ T cells, effector memory CD4+ T cells, central memory CD4+ T cells, and CD3+CD4+ CD25+ T cells were significantly lower in severe patients. The naive T cell/CD4 + EM T cell ratio, which is an indicator of the differentiation from naive T cells to memory cells, was relatively reduced in severe disease. Peripheral CD4+CD8+ double-positive T cells were notably lower in severe presentations of the disease (median DP T cells 11.12 µL vs 1.95 µL; p< 0.001). CONCLUSIONS: As disease severity increases in COVID-19 infection, the number of T cell subsets decreases significantly. Suppression of differentiation from naive T cells to effector memory T cells is the result of severe impairment in adaptive immune functions. Peripheral CD4+CD8+ double-positive T cells were significantly reduced in severe disease presentations and may be a useful marker to predict disease severity.

RESUMO OBJETIVO: A pandemia de COVID-19 tem afetado o mundo todo, constituindo uma ameaça grave para a saúde humana. As células T desempenham um papel crítico na imunidade celular contra infecções virais. Procuramos desvendar a relação entre sub grupos de células T e a severidade da doença. MÉTODOS: Um total de 40 pacientes com COVID-19 foram aleatoriamente recrutados para o presente estudo transversal. Todos os casos foram confirmados por RT-PCR quantitativo. Os pacientes foram divididos em dois grupos equivalentes, um grave e um não-grave. Os dados da avaliação clínica, laboratorial e da citometria de fluxo foram obtidos para ambos os grupos e comparados. RESULTADOS: Os subconjuntos de linfócitos, células T CD4+ e CD8+, células T de memória CD4+, células T de memória CD8+, células T CD4+ virgens, células T efetoras CD4+, células T de memória central CD4+ e células T CD3+ CD4+ CD25+ estavam significativamente mais baixas nos pacientes graves. A razão células T virgens/células T efetoras TCD4+, que é um indicador da diferenciação entre células T virgens e células de memória, estava relativamente reduzida em casos graves da doença. As células T duplo-positivas CD4+CD8+ periféricas estavam notavelmente mais baixas em casos graves da doença (mediana das células T DP: 11,12 µL vs. 1,95 µL; p< 0,001). CONCLUSÃO: Conforme aumenta a gravidade da doença nos casos de COVID-19, o número de subconjuntos de células T diminui significativamente. A supressão da diferenciação de células T virgens para células T efetoras é o resultado do comprometimento grave das funções imunológicas adaptativas. As células T duplo-positivas CD4+CD8+ periféricas estavam notavelmente mais baixas em casos graves da doença e podem ser um marcador útil para predizer a severidade da doença.

Intraoperative hemorrhage and increased spleen volume are risk factors for conversion to open surgery in patients undergoing elective robotic and laparoscopic splenectomy.

OBJECTIVES: Minimal invasive surgery is one of the most popular treatment approaches which is safe and effective in experienced hands in different clinical practices. In the present study, we aimed to evaluate the risks factors for conversion to open splenectomy and the performance of indirect hilum dissection technique. MATERIAL AND METHODS: A total of 56 patients who underwent laparoscopic or robotic splenectomy for isolated spleen diseases were included into the study. Patients were divided into two groups as robotic or laparoscopic splenectomy (Group 1; n= 48) and conversion to open surgery (Group 2; n= 8). Patients were retrospectively evaluated according to clinical, biochemical, hematological and microbiological parameters and morbidity. RESULTS: No statistically significant difference was found between the groups in terms of age, gender, body mass index (BMI), ASA score, co-morbid disease, operation time, hospital stay, follow-up period, accessory spleen, diagnosis, international normalized ratio (INR), red cell distribution width (RDW), platelet distribution width (PDW), platelet to lymphocyte ratio (PLR), neutrophil to lymphocyte ratio (NLR), reapplication, splenosis, surgical site infection, vascular thrombus and incisional hernia (p> 0.05). On the other hand, intraoperative splenic hilum hemorrhage and increased spleen size (p <0.05) were higher in the conversion to open surgery group. In logistic regression analysis, intraoperative splenic hilum hemorrhage (B= 4.127) (OR= 61.974) (95% CI= 3.913-981.454) (p= 0.003) and increased spleen volume (B= 3.114) (OR= 22.509) (95% CI= 1.818-278.714) (p= 0.015) were found as risk factors for conversion to open surgery. CONCLUSION: Intraoperative hemorrhage from the splenic hilum and increased spleen volume (> 400 cm3) are risk factors for conversion to open splenectomy in patients undergoing elective robotic or laparoscopic splenectomy. Indirect splenic hilum dissection can decrease intraoperative hemorrhage and conversion to open surgery.

A Multi-Center Study on the Efficacy of Eltrombopag in Management of Refractory Chronic Immune Thrombocytopenia: A Real-Life Experience

Objective: The aim of the present study was to evaluate the efficacy and safety of eltrombopag, an oral thrombopoietin receptor agonist, in patients with chronic immune thrombocytopenia (ITP). Materials and Methods: A total of 285 chronic ITP patients (187 women, 65.6%; 98 men, 34.4%) followed in 55 centers were enrolled in this retrospective cohort. Response to treatment was assessed according to platelet count (/mm3) and defined as complete (platelet count of >100,000/mm3), partial (30,000-100,000/mm3 or doubling of platelet count after treatment), or unresponsive (<30,000/mm3). Clinical findings, descriptive features, response to treatment, and side effects were recorded. Correlations between descriptive, clinical, and hematological parameters were analyzed. Results: The median age at diagnosis was 43.9±20.6 (range: 3-95) years and the duration of follow-up was 18.0±6.4 (range: 6-28.2) months. Overall response rate was 86.7% (n=247). Complete and partial responses were observed in 182 (63.8%) and 65 (22.8%) patients, respectively. Thirty-eight patients (13.4%) did not respond to eltrombopag treatment. For patients above 60 years old (n=68), overall response rate was 89.7% (n=61), and for those above 80 years old (n=12), overall response rate was 83% (n=10). Considering thrombocyte count before treatment, eltrombopag significantly increased platelet count at the 1st, 2nd, 3rd, 4th, and 8th weeks of treatment. As the time required for partial or complete response increased, response to treatment was significantly reduced. The time to reach the maximum platelet levels after treatment was quite variable (1-202 weeks). Notably, the higher the maximum platelet count after eltrombopag treatment, the more likely that side effects would occur. The most common side effects were headache (21.6%), weakness (13.7%), hepatotoxicity (11.8%), and thrombosis (5.9%). Conclusion: Results of the current study imply that eltrombopag is an effective therapeutic option even in elderly patients with chronic ITP. However, patients must be closely monitored for response and side effects during treatment. Since both response and side effects may be variable throughout the follow-up period, patients should be evaluated dynamically, especially in terms of thrombotic risk factors.

A Very Rare Presentation of Multiple Myeloma: Unilateral Raccoon Eye.

Multiple myeloma (MM), the second most common hematological malignancy, is caused by the accumulation of monoclonal plasma cells in bone marrow. It accounts for 10-15% of deaths from hematological malignancies and approximately 2% of deaths from cancer. The median age at presentation is 70 years old. The diagnosis is incidental in 30% of cases. MM is often discovered through routine blood screening with a large gap between the total protein and the albumin levels. Two thirds of patients complain of bone pain, especially lower back pain. MM could be diagnosed after a pathologic fracture occurs in one third of patients. Presentation with symptoms related to hyperviscosity, hypercalcemia and bleeding tendency could also be observed. A rare presentation of MM is peri-orbital ecchymotic lesion (raccoon eye). Here, we report a 64 years old, male patient presented with unilateral raccoon eye and high erythrocyte sedimentation rate (ESR) to internal medicine outpatient. The patient was referred to hematology outpatient and was diagnosed with multiple myeloma.
