Is antimicrobial prophylaxis necessary for lymphoma patients? A single centre, real-life experience.

BACKGROUND: Prophylaxis is strongly recommended in patients with hematological malignancy who are usually at higher risk for infection and neutropenic fever. It is still unclear whether or not there is a definite need for antimicrobial prophylaxis in intermediate-risk hematology patients such as those with lymphoma. METHODS: A retrospective analysis was made of patients admitted from January 2009 to December 2017 to the Hematology Department of Diskapi Yildirim Beyazit Training and Research Hospital, a tertiary referral hospital in Ankara, Turkey. The study included patients who were diagnosed with any type of lymphoma and given chemotherapy. Routine antimicrobial prophylaxis was administered to 127 lymphoma patients, and not to 65 lymphoma patients. These two groups were compared in respect of the incidence of total infection episodes (IE), febrile neutropenia episodes, and nonneutropenic clinically documented infection episodes. RESULTS: For all patients with lymphoma and subtypes of non-Hodgkin lymphoma or Hodgkin lymphoma, no significant difference was determined between the groups in respect of the total incidence of IE, febrile neutropenia and nonneutropenic clinically documented infection both during the first-line chemotherapy and throughout the total follow-up period (p > 0.05). Patients with prophylaxis had a higher incidence of IE, which was treated with parenteral antibiotics both during the first-line chemotherapy and throughout the total follow-up period (p < 0.05). CONCLUSION: Antimicrobial prophylaxis was seen to have no effect on the total incidence of infection episode and febrile neutropenia. Therefore, the routine use of antimicrobial prophylaxis should not be recommended for patients with lymphoma.

The rare coexistence of high titer inhibitor development and gastrointestinal stromal tumor in a patient with severe hemophilia: A case report.

Hemophilia is a hereditary disease with impaired blood coagulation due to a genetic deficiency of blood coagulation factors. The development of inhibitors further complicates the course of the disease and management. The case is here reported of a haemophilia patient who presented with coexisting development of high titer inhibitor with Gastrointestinal Stromal Tumor (GIST) diagnosis and was admitted with upper gastrointestinal system bleeding. The patient had no prior history of inhibitor presence. During all procedures including surgery, excellent hemostasis was achieved with rFVIIa treatment and no hemorrhagic complication was observed. To the best of our knowledge, this constitutes the first reported case of GIST associated with inhibitor development in a hemophilia A patient.

The Predictive Role of the Neutrophil/Lymphocyte Ratio in Survival with Multiple Myeloma: A Single Center Experience.

BACKGROUND: Recent studies have shown a positive correlation between tumor-related immune response markers and the poor outcome in solid tumors. In this study, we aimed to investigate the neutrophil/lymphocyte ratio (NLR) in multiple myeloma. To the best of our knowledge, this would be the second report concerning this topic. METHODS: We retrospectively reviewed the data for 52 multiple myeloma patients. The patients were grouped using the baseline NLR as NLR ≤ 1.72 and NLR > 1.72 using receiver operating characteristic analysis to determine a cut off. We compared the two groups in terms of both the known prognostic factors of the myeloma and the overall survival (OS). RESULTS: Our study showed that NLR is associated with C-reactive protein and ß2 microglobulin (P = 0.02 and P = 0.001, respectively). The patients with NLR > 1.72 had significantly worse stages, performance status, and kidney functions. The whole group's OS was estimated as 35.1 months while the patients with lower NLR had better OS when compared with those with NLR > 1.72 (42.75 and 26.14 months, respectively, P: 0.04). CONCLUSION: Neutrophil/lymphocyte ratio, which is associated with stage, performance status, and kidney functions, can be used in daily practice as a predictor for survival in multiple myeloma. Simply adding NLR to the routine charts may enrich our data for larger studies.

Mental status and physical activity in patients with homozygous familial hypercholesterolemia: A subgroup analysis of a nationwide survey (A-HIT1 registry).

BACKGROUND: Homozygous familial hypercholesterolemia (HoFH) is a rare, life-threatening disease due to high serum low-density lipoprotein (LDL) cholesterol levels. LDL cholesterol-lowering interventions are fundamental for patients with HoFH. OBJECTIVE: It was aimed to investigate the association between the mental status of patients with HoFH and healthy lifestyle behaviors. METHODS: This subgroup analysis of the A-HIT1 population included the data of patients aged ≥18 years with a clinical diagnosis of HoFH undergoing therapeutic LDL apheresis. Besides the demographic and clinical characteristics of patients, healthy lifestyle behaviors were assessed, and psychiatric symptoms were screened by Symptom Check List (SCL-90-R). RESULTS: The highest percentage for pathology was observed in dimensions of obsessive-compulsive, somatization, interpersonal sensitivity, and depression in SCL-90-R. Patients with any cardiovascular condition have more psychiatric symptoms in different fields of SCL-90-R. The outcomes of the correlative analysis indicated that lower the age of the first coronary event better the psychiatric status, probably denoting a better adaptation to disease and its treatment. Among 68 patients, 36 patients were not exercising regularly. Patients with regular physical activity had significantly lower scores in most dimensions of SCL-90-R and there was no association between regular physical activity and other investigated variables. The strongest predictor of regular exercising was global severity index of SCL-90-R. CONCLUSION: In the HoFH population, there was a high prevalence of mental disturbances. Better psychiatric status was associated with regular exercising. Therefore, assessing the mental status of patients with HoFH and referring patients in need, to a psychiatrist, may improve the outcome of patients.

Clinical management, psychosocial characteristics, and quality of life in patients with homozygous familial hypercholesterolemia undergoing LDL-apheresis in Turkey: Results of a nationwide survey (A-HIT1 registry).

BACKGROUND: Homozygous familial hypercholesterolemia (HoFH) is a rare, life-threatening inherited disease leading to early-onset atherosclerosis and associated morbidity. Because of its rarity, longitudinal data on the management of HoFH in the real world are lacking, particularly on the impact the condition has on quality of life (QoL), including the impact of the extracorporeal lipid removal procedure apheresis (LA). METHODS: The A-HIT1 study included 88 patients with HoFH aged ≥12 years receiving regular LA in 19 centers in Turkey. Demographic and disease characteristics data were obtained. For patients aged ≥18 years, additional data on psychosocial status were obtained via the SF-36 score, the Hospital Anxiety and Depression Scale, and a HoFH-specific questionnaire. RESULTS: There was no standardized approach to therapy between centers. Mean (±SD) frequency of LA sessions was every 19.9 (±14) days, with only 11.6% receiving LA weekly, and 85% of patients were not willing to increase LA frequency. The most common concerns of patients were disease prognosis (31%), and physical, aesthetic, and psychological problems (27.5%, 15.9%, and 11.6%, respectively). Lower age at diagnosis was associated with better QoL, lower anxiety, improved functioning, and greater emotional well-being compared to later diagnosis. CONCLUSIONS: These findings demonstrate that adult patients with HoFH undergoing LA, experience significant impairment of QoL with an increased risk of depression. From patients' point of view, LA is time-consuming, uncomfortable, and difficult to cope with. The speed of diagnosis and referral has a considerable impact on patient well-being.

Combination therapy with azacitidine, etoposide, and cytarabine in the treatment of elderly acute myeloid leukemia patients: A single center experience.

AIMS: The prognosis of acute myeloid leukemia (AML) in elderly patients is worse due to age and comorbidities. Lately, monotherapy with hypomethylating agents like azacitidine (Aza) has been used to prolong overall survival (OS) in AML patients. Herein, we present a retrospective study investigating treatment responses and OS of Aza in combination with etoposide (Eto) and cytarabine (ARA-C) in elderly. MATERIALS AND METHODS: In this study, therapies and outcomes of 37 newly diagnosed AML patients, >60 years old, and ineligible for intensive chemotherapy were investigated retrospectively. Patients were grouped according to the treatments they received as follows - Group 1: low-dose conventional therapies as hydroxyurea, low-dose ARA-C, or best supportive care (n = 11); Group 2: Aza alone (n = 6); Group 3: Aza in combination with Eto and ARA-C (Aza + Eto + ARA-C, n = 20). RESULTS: It was found that an Aza + Eto + ARA-C combination therapy had significantly better overall response rates (P = 0.002). Combination group had significantly better OS than Group 1 (8 months vs. 1 month, P < 0.001), the difference between combination and monotherapy was not significant. The OS was also associated with age and performance status, but the difference was still statistically significant after adjustment for these factors, especially for patients with younger age and better performance. CONCLUSIONS: We concluded that combination therapy of Aza with Eto and ARA-C increases response rates, and prolong survival for this poor prognosed patient group. We believe that larger controlled studies investigating Aza combinations with other antileukemic drugs will contribute to the development of tolerable treatment protocols for elderly AML patients.

Infections in patients with lymphoma: An analysis of incidence, relationship and risk factors.

INTRODUCTION: Bacterial infections and febrile neutropenia (FN) are major causes of morbidity and mortality in patients with hematological malignancy. The aim of this study was to investigate the incidence and risk factors of infections in lymphoma patients. METHODOLOGY: This retrospective study was conducted on 200 lymphoma patients diagnosed and treated between January 2009 and December 2017 in Diskapi Yildirim Beyazit Training and Research Hospital, a tertiary referral hospital in Ankara, Turkey. RESULTS: The mean follow-up period was 20.09 ± 19.81 months. The incidence of infection episode (IE) was 32.5% (65/200) and FN was 18.5% (37/200). Analysis of the data revealed that patients with IE had significantly higher rates of diagnosis of primary central nervous system lymphoma (PCNSL), lower baseline hemoglobin, lower baseline hematocrit, higher baseline lactate dehydrogenase levels, higher usage of central cathater, and a higher number of chemotherapy lines compared to patients with no IE. In logistic regression analysis, disease subtype of PCNSL, usage of central catheter and lactate deyhydrogenase (LDH) were found to increase the risk of infection. The odds ratio for PCNSL was 37.866 (p = 0.003), 2.679 for central catheter (p = 0.008) and 1.001 for LDH (p = 0.011). CONCLUSIONS: The risk of infection in patients with lymphoma was associated with central catheter usage, higher LDH levels and a diagnosis of PCNSL. Baseline hematological parameters were not determined to have any impact on the occurrence of infection. Patients with these risk factors should be monitored more carefully and the maximum level of infection prevention should be taken.

A nation-wide survey of patients with homozygous familial hypercholesterolemia phenotype undergoing LDL-apheresis in Turkey (A-HIT 1 registry).

BACKGROUND AND AIMS: Homozygous familial hypercholesterolemia (HoFH) is a genetic condition characterized by lethally high levels of low-density lipoprotein cholesterol (LDL-C) from birth, and requires rapid and aggressive intervention to prevent death due to coronary heart disease and/or atherosclerosis. Where available, lipoprotein apheresis (LA) is the mainstay of treatment to promote survival. METHODS: A-HIT1 registry was conducted with the aim of providing insight to the real-life management of HoFH patients undergoing LA in Turkey, where LA procedures are fully reimbursed and widely available. Participating centers provided patient information, including family history, treatment patterns and relevant laboratory values, via a standard questionnaire. RESULTS: The study evaluated 88 patients (mean age: 27 ±â€¯11 years, 41 women) in 19 centers. All patients were receiving regular LA with a clinical diagnosis of HoFH. Mean age at first symptom disease was 10 ±â€¯10 years, and at diagnosis it was 12 ±â€¯11 years; 74.7% were diagnosed before age 15 years; and only 31% before the age of 7. First referral of most patients was to pediatricians. Early onset coronary artery disease was present in 57.8% of patients. Mean age at first LA was 21 ±â€¯12 years. Only 11 (12.5%) patients were undergoing LA weekly. Mean frequency of apheresis sessions was 19 ±â€¯13 days. For the last four LA sessions, LDL-C levels reached the target in only in 5.7% of patients. CONCLUSIONS: Diagnosis of HoFH is delayed, and LDL targets are not reached. LA frequencies are not optimal. Urgent attention is needed to support the survival of patients with HoFH.

What have we learned from Turkish familial hypercholesterolemia registries (A-HIT1 and A-HIT2)?

BACKGROUND AND AIMS: Familial hypercholesterolemia (FH) is a common genetic disease of high-level cholesterol leading to premature atherosclerosis. One of the key aspects to overcome FH burden is the generation of large-scale reliable data in terms of registries. This manuscript underlines the important results of nation-wide Turkish FH registries (A-HIT1 and A-HIT2). METHODS: A-HIT1 is a survey of homozygous FH patients undergoing low density lipoprotein (LDL) apheresis (LA). A-HIT2 is a registry of adult FH patients (homozygous and heterozygous) admitted to outpatient clinics. Both registries used clinical diagnosis of FH. RESULTS: A-HIT1 evaluated 88 patients (27 ±â€¯11 years, 41 women) in 19 centers. All patients were receiving regular LA. There was a 7.37 ±â€¯7.1-year delay between diagnosis and initiation of LA. LDL-cholesterol levels reached the target only in 5 cases. Mean frequency of apheresis sessions was 19 ±â€¯13 days. None of the centers had a standardized approach for LA. Mean frequency of apheresis sessions was every 19 ±â€¯13 (7-90) days. Only 2 centers were aware of the target LDL levels. A-HIT2 enrolled 1071 FH patients (53 ±â€¯8 years, 606 women) from 31 outpatients clinics specialized in cardiology (27), internal medicine (1), and endocrinology (3); 96.4% were heterozygous. 459 patients were on statin treatment. LDL targets were attained in 23 patients (2.1% of the whole population, 5% receiving statin) on treatment. However, 66% of statin-receiving patients were on intense doses of statins. Awareness of FH was 9.5% in the whole patient population. CONCLUSIONS: The first nationwide FH registries revealed that FH is still undertreated even in specialized centers in Turkey. Additional effective treatment regiments are urgently needed.

Comparative Evaluation of Common Comorbidity Scores and Freiburger Comorbidity Index as Prognostic Variables in a Real Life Multiple Myeloma Population.

Multiple myeloma (MM) is a disease of the geriatric population with a median age at diagnosis of 69 years but most clinicians consider performance status and comorbidities rather than chronological age in determining prognosis and treatment. The purpose of this study was to assess whether and which comorbidity indices predict survival in a real life population of MM. We calculated Charlson Comorbidity Index (CCI), age combined Charlson index (CCI-age), Hematopoietic cell transplantation-specific comorbidity index (HCT-SCI) and Freiburger comorbidity index (FCI) retrospectively for 66 MM patients and compared their impact on treatment responses and overall survival (OS). Treatment response was significantly worse in groups with high CCI, CCI-age, HCT-SCI scales (p < 0.05), but FCI's effect on treatment response was not significant. However, while no significant relationship was determined between other comorbidity indices with OS, it was related only with FCI-CI (p = 0.006). FCI, developed in this patient group, was the only prognostic index with a significant effect on OS in the evaluation of comorbidities in MM patients with different scores, but its relationship to treatment responses was not significant contrary to other indices. While this small patient group gave us hope regarding the use of FCI in practice, multi-center studies are still required.
