Roles of ghrelin, hepcidin and HIF-2α in iron metabolism in iron deficiency anemia.

OBJECTIVES: This study investigates the roles of HIF-2α, hepcidin, and ghrelin in iron deficiency anemia (IDA), the most widespread nutritional disorder globally. MATERIAL AND METHODS: Fifty IDA patients (18-50 years, BMI 19-25) and 40 healthy volunteers were studied. Hemoglobin, ferritin, hepcidin, HIF-2α, and ghrelin levels were analyzed. RESULTS: IDA patients showed lower hemoglobin, ferritin, hepcidin, and ghrelin levels than the control group, but HIF-2α levels were similar. Positive correlations were observed in both groups between hepcidin and HIF-2α (p < 0.001), hepcidin and ghrelin (p < 0.001), and HIF-2α and ghrelin (p < 0.001). Hemoglobin was correlated positively with HIF-2α, and ferritin was correlated positively with HIF-2α in the patient group. CONCLUSION: The study suggests that the low hepcidin levels in IDA patients enhance iron absorption. The lack of significant HIF-2α level differences may be due to the absence of chronic hypoxia in current hemoglobin levels of IDA patients. Moreover, the low ghrelin levels in patients and the correlations between ghrelin, hepcidin, and HIF-2α in both groups indicate their involvement in iron metabolism.

Real-life experience with plasmapheresis in newly diagnosed multiple myeloma accompanied by acute kidney injury.

OBJECTIVES: The aim of this study was to retrospectively evaluate the effect of plasmapheresis treatment concomitant with chemotherapy and the number of sessions on renal improvement and survival in patients with newly diagnosed multiple myeloma (MM) presenting with acute kidney injury (AKI). MATERIAL AND METHODS: Retrospective analysis was performed on 55 newly diagnosed MM patients who were presented with AKI to the Hematology Clinic of University of the Health Sciences Antalya Training and Research Hospital between 2013 and 2021. RESULTS: The study included 55 patients between 39 and 91 years of age and comprised 22 (40%) women and 33 (60%) men. Forty-eight (87.3%) patients were treated with plasmapheresis and chemotherapy. Based on the median number of plasmapheresis sessions, the patients were grouped as ≤ 3 and > 3. A significant difference was observed in both groups between the mean values of repeated measurements at the time of diagnosis, after completion of plasmapheresis treatment, and at 1 month of plasmapheresis, when statistics of differences were evaluated for urea, creatinine, estimated glomerular filtration rate (eGFR) (ml/min), total protein, albumin, and globulin (p < 0.05); however, there was no difference between these parameters and the number of plasmapheresis sessions. The 1.16 (0.56-2.38) fold higher risk of ex found in patients with ≤ 3 plasmapheresis sessions compared to those with > 3 was not statistically significant (p > 0.05). CONCLUSION: It was observed that plasmapheresis is beneficial in the short term for renal recovery in the treatment of MM with AKI and that > 3 plasmapheresis sessions have no superior effectiveness in renal improvement or survival.

Evaluation of cerebellum volume and trunk oscillation velocity in cases with adolescent idiopathic scoliosis: a preliminary report.

PURPOSE: It has been suggested that the cause of the balance disorder seen in adolescent idiopathic scoliosis (AIS) originates from the central nervous system. However, the extent of the balance problem and the dysfunction of which part of the central nervous system has not been investigated in detail. This study aimed to correlate the values obtained by balance analysis and cerebellum volume measurement in female individuals with AIS with healthy individuals. METHODS: Cerebellum volume was calculated via the cloud-based software " https://volbrain.upv.es " using brain magnetic resonance images of 27 healthy and 26 individuals with AIS. The duration of stay in the test positions, the movement strategy used during this time and the amount of postural sway were analyzed by using a computer-assisted force platform and compared statistically. RESULTS: Significant differences were found between the AIS and control groups in cerebellum total volume, vermis cerebelli volume (cm3), and trunk oscillation velocity (mm/s) parameters (p < 0.05). Cerebellum and vermis cerebelli volumes were found to be lower and trunk oscillation velocity was found to be greater in patients with AIS. CONCLUSION: Balance problems in patients with AIS are correlated with decreased cerebellum volume and increased trunk oscillation velocity.

Investigation of the color discrimination ability using the Farnsworth-Munsell 100-hue test and structural changes by SS-OCT in patients with transfusion-dependent beta-thalassemia.

AIM: This study aimed to examine the color discrimination ability of patients with transfusion-dependent beta-thalassemia (TDß-T) in detail using the Farnsworth Munsell (FM) 100-hue test and to evaluate structural changes by swept source-optical coherence tomography (SS-OCT). MATERIAL AND METHODS: This prospective, sectional study included 40 patients (79 eyes) with TDß-T and 21 controls (42 eyes). The volunteers underwent a detailed ophthalmological examination and SS-OCT (DRI-OCT, Triton) imaging. Excluded were those with congenital color vision defects detected with the Ishihara pseudoisochromatic test. The patients' color vision was examined using the FM 100-hue test. The total error score (TES), the blue-yellow local error score (b-y LES), and the red-green local error score (r-g LES) were calculated. p <0.05 was considered significant. RESULTS: The mean age was 30.34±6.94 years in the patient group and 32.26±6.43 years in the control group (p = 0.078). The patient group had a significantly lower hemoglobin level (9.25±0.87 g/dL vs. 14±1.79 g/dL, p <0.001) and a significantly higher ferritin level (2665.56±2658.05 µg/L vs. 52.87±69.59 µg/L, p<0.001) compared to the control group. The mean TES, b-y LES, and r-g LES were higher in the patients than in the controls (64.84±30.18 vs. 28.45±16.55, p<0.001, 34.21±17.54 vs. 15.67±10.07, p <0.001, and 29.32±15.72 vs. 12.12±7.94, p<0.001, respectively). The patients had a higher b-y LES than r-g LES (34.21±17.54 vs. 29.32±15.72, p = 0.015). Choroidal thickness was lower in the patients than in the controls (284.34±63.55 µm vs. 324.98±88.05 µm, p = 0.043). CONCLUSION: We found that the color discrimination ability of the patients with TDß-T was reduced in both the r-g and b-y color axes compared to the controls, and their color discrimination ability in the b-y color axis was more affected than in the r-g axis.

Frontal Plane QRS-T Angle as a Marker of Cardiac Iron Overload in Patients with Beta Thalassemia Major.

Introduction: Cardiomyopathy due to myocardial iron deposition is the leading cause of death in transfusion- dependent beta-thalassemia major (ß-TM) patients. Although cardiac T2* magnetic resonance imaging (MRI) can be used for the early detection of cardiac iron level before the onset of symptoms associated with iron overload, this expensive method is not widely available in many hospitals. Frontal QRS-T angle is a novel marker of myocardial repolarization and is associated with adverse cardiac outcomes. We aimed to investigate the relationship between cardiac iron load and f(QRS-T) angle in patients with ß-TM. Methods: The study included 95 ß-TM patients. Cardiac T2* values under 20 were considered to indicate cardiac iron overload. The patients were divided into two groups according to the presence or absence of cardiac involvement. Laboratory and electrocardiography parameters, including frontal plane QRS-T angle, were compared between the two groups. Results: Cardiac involvement was detected in 33 (34%) patients. Multivariate analysis showed that frontal QRS-T angle independently predicted cardiac involvement (p < 0.001). An f(QRS-T) angle of ≥ 24.5° had a sensitivity of 78.8% and a specificity of 79% in detecting the presence of cardiac involvement. In addition, a negative correlation was found between cardiac T2* MRI value and f(QRS-T) angle. Conclusions: A widening f(QRS-T) angle could be considered a surrogate marker of MRI T2* to detect cardiac iron overload. Therefore, calculating the f(QRS-T) angle in thalassemia patients is an inexpensive and simple method for detecting the presence of cardiac involvement, especially when cardiac T2* values cannot be determined or monitored.

Analysis of changes in brain morphological structure of taekwondo athletes by diffusion tensor imaging.

OBJECTIVE: Taekwondo, which is the most preferred sport among the martial arts, is known to improve individuals physically, spiritually and mentally. The aim of this study is to reveal the effect of teakwondo sport on the brain and brain structures. DESIGN;: 30 taekwondo athletes and 15 control groups were included in this study. Diffusion tensor MR images of each participant were taken. The information was obtained by the self-declaration of the athletes, whether they were sports years, amateur or elite. METHOD: Total brain volume and volumes of white matter, gray matter, frontal lobe, precentral gyrus, corticospinal tract, basal nuclei, postcentral gyrus, hippocampus and amigdala and the ratio of these volumes to total brain volume were evaluated statistically between the groups using MriCloud software and ROIEditor program. RESULTS: An increase in total brain volume, gray matter, frontal lobe and precentral gyrus volume in athletes was associated with taekwondo training. When the ratio of brain parts to total brain volume was examined, it was determined that there was a difference in the ratio of gray matter, white matter volumes in amateur athletes, right frontal lobe, left corticospinal tract, right postcentral gyrus volumes in elite athletes, and left postcentral gyrus volumes of both athletes compared to sedentary individuals. CONCLUSIONS: The increase in the volume of gray matter, frontal lobe, postcentral gyrus and corticospinal tract together with the brain volume shows that taekwondo exercise contributes to physical, spiritual and mental development.

Optical coherence tomography angiography findings in transfusion-dependent beta-thalassemia patients with and without splenectomy.

BACKGROUND: Ocular involvement is common in transfusion-dependent beta-thalassemia (TDß-T) patients. We aimed to investigate the effect of splenectomy on optical coherence tomography angiography (OCTA) findings in TDß-T patients. METHODS: The study is a prospective cross-sectional study. A total of 45 eyes of 23 patients with splenectomy (34.04±8.83 years), 18 eyes of 9 patients without splenectomy (27.44±5.43 years), and 54 eyes of 27 controls (33.22±6.44 years) were included. Vessel density in superficial capillary plexus, deep capillary plexus and radial peripapillary capillary, foveal avascular zone, choriocapillaris flow area, choroidal and retinal thickness detected by OCTA were evaluated. p < 0.05 was considered significant. RESULTS: Vessel density of superficial capillary plexus and deep capillary plexus were similar in patients with and without splenectomy, and controls. Choriocapillaris flow area was significantly decreased in patients with splenectomy than that in those without splenectomy and controls (2.02±0.12 vs. 2.17±0.1 and 2.14±0.12; p < 0.001). Choroidal thickness was significantly lower in patients without splenectomy than in patients with splenectomy and controls (260.05±61.02 vs. 305.11±42.13 and 298.89±29.14, p = 0.008). Parafoveal and perifoveal thickness of the full retina and outer retina were significantly lower in patients without splenectomy than in patients with splenectomy and controls (301.06±10.0, 279.78±10.28 vs. 311.04±14.89, 290.87±13.67 and 316.63±13.57, 289.56±9.31, p < 0.001 and p = 0.002; 174.72±7.81, 167.17±6.21 vs. 182.87±8.81, 173.60±7.09 and 185.11±9.26, 173.96±6.79, p = 0.001 and p < 0.001, respectively). CONCLUSIONS: OCTA findings can provide information about the microvascular effects of splenectomy on the retina of patients with TDß-T.

The role of pineal gland volume in the development of scoliosis.

PURPOSE: Adolescent idiopathic scoliosis (AIS) is believed to be caused by genetic, neurological, osseous growth anomalies, histological variables including muscle fiber percentage and core structure changes, metabolic and hormonal dysfunction, vestibular dysfunction, and platelet microarchitecture. The objective of this study was to contribute to the determination of the cause of AIS by analyzing the changes in pineal gland volume in AIS cases. METHODS: Study (AIS) and control group were each comprised of 26 patients who met the inclusion requirements. Scoliosis radiograph and MRI of the pineal glands were used for radiological examinations. The distribution of age, gender, Risser grading for skeletal radiological development, and sexual maturation according to Tanner categorization were uniform and statistically insignificant between groups. RESULTS: When the pineal gland volumes of the cases were evaluated according to age, the AIS group was found to have significantly reduced pineal gland volumes in all age groups. The pineal gland volume was found to be 38.1% lower in the AIS group compared to the control group (p˂0.001). In the AIS group, patients aged 13 years had the lowest pineal gland volume (77.2 ± 13.86 mm3), while patients aged 15 years had the highest volume (97.9 ± 16.47 mm3). CONCLUSION: Changes in pineal gland volume support the role of the pineal gland in the etiopathogenesis of AIS.

Is the Integration Problem in the Sensoriomotor System the Cause of Adolescent Idiopathic Scoliosis?

PURPOSE: The reason behind the balance control disorder seen in adolescent idiopathic scoliosis (AIS) has been suggested as a central nervous system dysfunction, yet it has not been investigated in detail whether this problem originates from sensory, motor, or from both systems. This study aimed to reveal the differences in the pathways that provide proprioceptive sense, motor control, and coordination between these 2 systems in female individuals with AIS. METHODS: Brain Diffusion Tensor Imaging was applied to 30 healthy individuals and 30 Lenke type 1 AIS patients. All of the individuals included in the study were predominantly right-handed and aged between 10 and 18. Diffusion tensor imaging of both groups were performed bilateral tractography on the corticospinal tract (CS tr), medial lemniscus (ML), superior longitudinal fasciculus (SLF), and inferior longitudinal fasciculus (ILF) tracts using DSI Studio software. RESULTS: Significant differences in the parameters of CS tr, ML, SLF, ILF pathways were found between the AIS and the control groups. In the AIS group, significant differences were found in the fiber count and fiber ratio of the ML that carries the proprioceptive sense and CS tr, which is responsible for the somatomotor system. There were also significant differences between the left and right CS tr, ML, SLF, and ILF pathways of the AIS group ( P <0.05). CONCLUSIONS: Differences in the CS tr, ML, SLF, and ILF pathways may trigger muscular asymmetry and cause postural instability and thus spinal deformity in AIS.

Turkey real-life data: demographic features, treatment results and effects of comorbidities in chronic myeloid leukemia.

Aim: This study aimed to identify patient characteristics, treatment patterns and outcomes and to evaluate the effects of presence of comorbidities at diagnosis in chronic phase (CP)-chronic myeloid leukemia (CML) patients in Turkey. Materials & methods: Hospital records between 2005 and 2018 were retrospectively reviewed. Results: Of 861 CP-CML patients included, 31% had at least one comorbidity at diagnosis. Sex, cardiovascular disease status at diagnosis and molecular (at least major) and cytogenetic (partial and complete) responses were the independent predictors of survival. Conclusion: The response rates of CP-CML patients to the tyrosine kinase inhibitors were satisfactory. In addition to tolerability and side effect profiles of drugs, comorbidity status of patients should also be considered in treatment choice in CML patients.

Patient characteristics and management practices in chronic myeloid leukemia in Turkey: reflections from an expert meeting.

INTRODUCTION: The therapeutic landscape of chronic myeloid leukemia (CML) has evolved significantly since the introduction of imatinib. The European LeukemiaNet (ELN) recommendations serve as a guide for diagnosis, treatment, and monitorization of CML, but availability and accessibility of diagnostic tools and medications affect their applicability. AREAS COVERED: This article provides an overview of the current clinical management of CML in Turkey with reference to the key outputs of the online expert meeting held in November 2020. The applicability of the ELN 2020 recommendations for treating CML in clinical practice was also discussed. EXPERT OPINION: Imatinib is the only reimbursed and the most preferred first-line treatment in CML restricting the upfront use of second-generation tyrosine kinase inhibitors (TKIs), thereby limiting the applicability of treatment-free remission approach in Turkey. The ELN recommendations about using the EUTOS Long-Term Survival (ELTS) score for risk assessment and focusing on patient reported outcomes and quality of life can be enhanced with educational activities. The widespread availability of standardized technical infrastructure for diagnosing and monitoring CML will contribute to better disease management. Establishing a sustainable national database for CML is valuable for observing patient characteristics and disease outcomes as well as the impact of treatment patterns over time.

Is scoliosis related to mastication muscle asymmetry and temporomandibular disorders? A cross-sectional study.

OBJECTIVE: Patients with adolescent idiopathic scoliosis (AIS) may face motor control problems and health disability barriers during mandibular movements and chewing. However, studies investigating the extent of these disadvantages, and possible associated factors are quite limited in patients with AIS. This study was conducted to gain a deeper perspective on the effect of AIS on temporomandibular disorders (TMD) and to contribute to the small amount of data on this subject. METHODS: Twenty-nine patients with AIS and 29 age- and sex-matched asymptomatic controls participated in this cross-sectional study. Cobb's method was used to measure scoliosis curves. In both groups, the volume of the masseter muscle was determined on magnetic resonance imaging, and Helkimo and Fonseca anamnestic indexes were used to evaluate temporomandibular joint (TMJ). RESULTS: It was observed that the TMD symptoms were higher in the AIS group (22.6- Helkimo and 1.2 - Fonseca) than the asymptomatic group (13.6 - Helkimo and 0.7 - Fonseca). There was no significant asymmetry in masseter volume in patients with AIS, however the volume of the masseter muscles was smaller in the AIS group (R = 14.6/L = 13.6) compared to the control group (R = 16.1/L = 16.2). CONCLUSIONS: The study results indicate that spinal curvatures affect the anatomical, biomechanical, and kinesiological features of the masticatory system, and individuals with AIS may experience more chewing problems than asymptomatic individuals. Examining musculoskeletal properties of masticatory system can provide information about the limitation of the TMJ in patients with AIS.

Decreased ovarian reserve and ovarian morphological alterations in female rat offspring exposed to a ketogenic maternal diet

SUMMARY OBJECTIVE: This study evaluates the effects of a ketogenic diet on morphology and follicle reserve. METHOD: Sixteen Sprague-Dawley rats were randomized into two groups: standard diet group (n=8) and ketogenic diet group (n=8). Rats were time mated. Dams were permitted to deliver spontaneously. The animals were monitored for the onset of puberty. All the rats were weighed and anesthetized, serum anti-Müllerian hormone level was measured, and the oviducts were removed. The morphological characteristics of follicles were determined and total ovarian volumes were calculated. RESULTS: The mean ovarian volume was statistically significantly lower in the ketogenic diet group compared to the standard diet group (14.41±0.99 mm3 versus 18.89±1.28 mm3) (p=0.000). The mean number of antral follicles was 13.63±1.80 in the standard diet group and 4.462±0.760 in the ketogenic diet group. The mean ovarian weight of the ketogenic diet group was significantly lower than that of the standard diet group (0.42±0.06 g versus 0.815±107 g). The mean anti-Müllerian hormone levels were significantly higher in the standard diet group compared to the ketogenic diet group (1.023±4.75 ng/mL versus 0.69±0.07 ng/mL) (p=0.000). The mean percentage of staining of Ki-67 was 35.28±4.75 in the standard diet group and 16.98±3.33 in the ketogenic diet group (p=0.000). CONCLUSION: Maternal ketogenic diet reduces ovarian follicular reserve in female offspring and has important implications for maintaining reproductive potential at a population level.

Restless leg syndrome in adult patients with ß-thalassemia major.

BACKGROUND AND PURPOSE: To investigate the quality of sleep and the presence of Restless Legs Syndrome (RLS) in the Turkish population with ß-thalassemia major (TM). The second aim was to assess the risk factors of RLS in TM adults. METHODS: The study sample comprised of 121 patients at least 18 years old with TM. The patients' socio-demographic information, body mass indexes (BMI), current medications, laboratory data were recorded. The patients were asked if they had a history of chronic kidney disease, diabetes mellitus (DM), and polyneuropathy. Restless legs syndrome was diagnosed according to the International Restless Legs Syndrome Study Group criteria. The sleep quality of the patients was assessed using the Pittsburgh Sleep Quality Index (PSQI) scale. The Epworth Sleepiness Scale (ESS) was used to assess excessive daytime sleepiness in the patients. RESULTS: The median age of the patients was 25 years (range 18-52). The mean BMI was 21.49±2.5 (R 14-26.5) for all patients. The prevalence of RLS was 5% in TM adult patients. The TM patients with RLS had no major complications of TM. The median PSQI global score of all patients was 3. Twenty-two (18.1%) patients had poor sleep quality. The reason for poor sleep quality was RLS symptoms in four patients (18%). There was no significant association between PSQI total score and blood parameters of the patients. Twelve (9.9%) patients had ESS scores greater than 10, which indicates excessive daytime sleepiness. CONCLUSION: The prevalence of RLS in TM patients was similar to that of the general Turkish adult population. These results indicate that RLS may occur in patients with TM, although they had a high level of serum ferritin.

Extracorporeal photopheresis in steroid-refractory chronic graft-versus-host disease: A retrospective multicenter study.

BACKGROUND AND OBJECTIVES: Extracorporeal photopheresis (ECP) is a treatment strategy in steroid-refractory chronic graft-versus-host disease (cGvHD). In this study, we aimed to share our multicenter experience using ECP in our steroid-refractory cGvHD patients. MATERIALS AND METHODS: In this multicenter observational retrospective study with the participation of four Turkish transplant centers, 100 patients with the diagnosis of steroid-refractory cGvHD who underwent ECP were analyzed. All ECP procedures were performed with the off-line system. RESULTS: Severe cGvHD was observed in 77 % of the patients. 50 % of the patients had more than 1 organ involvement. The overall response rate in cGvHD was 58 %, and the complete response (CR) rate was 35 %. The skin was the most involved organ, with a response rate of 61.2 % (CR rate 30.6 %) in cGvHD. At a median 13 months (1-261) follow-up, overall survival (OS) was 41 % (n = 41) and the mortality rate was 59 % (n = 59). Median overall survival (OS) was 2 months for non-responders and 91 months for responders (p < 0.001). Significant OS differences were observed for patients responding to ECP in cGvHD (HR = 4.1, p = 0.001) patients. CONCLUSIONS: ECP is a good therapeutic alternative and could be used earlier in patients with steroid-resistant cGvHD.

Extracorporeal photopheresis in the treatment of acute graft-versus-host disease: A multicenter experience.

BACKGROUND AND OBJECTIVES: Extracorporeal photopheresis (ECP) is one of the second-line treatment strategies in steroid-refractory acute graft-versus-host disease (aGvHD). We aimed to share our multicenter experience using ECP in our steroid-refractory aGvHD patients. MATERIALS AND METHODS: A retrospective observational series of 75 aGvHD patients from 4 transplant centers were analyzed. All ECP procedures were performed with the off-line system. All patients received ECP as second-line therapy. RESULTS: 74.7 % of aGvHD patients were grade 3 or 4. The overall response rate was 42.7 % (32/75) in aGvHD including 17 complete responses (22.7 %). Median follow-up was 6 months (range, 1-68). Median overall survival (OS) was 5 months for non-responders and 68 months for responders (p < 0.001). Twenty-seven (36 %) patients are alive, and 48 (64 %) patients have died. CONCLUSIONS: Early initiated ECP could be an effective treatment alternative in patients with steroid-refractory aGvHD.

Efficacy and Safety of Ibrutinib Therapy in Patients with Chronic Lymphocytic Leukemia: Retrospective Analysis of Real-Life Data

Objective: This study aimed to retrospectively evaluate the efficacy, safety, and survival outcome of single-agent ibrutinib therapy in chronic lymphocytic leukemia patients. Materials and Methods: A total of 136 patients (mean age ± standard deviation: 64.6±10.3 years, 66.9% males) who had received at least one dose of ibrutinib were included in this retrospective multicenter, noninterventional hospital-registry study conducted at 33 centers across Turkey. Data on patient demographics, baseline characteristics, laboratory findings, and leukemia-cell cytogenetics were retrieved. Treatment response, survival outcome including overall survival (OS) and progression-free survival (PFS), and safety data were analyzed. Results: Overall, 36.7% of patients were categorized as Eastern Cooperative Oncology Group (ECOG) class 2-3, while 44.9% were in Rai stage 4. Fluorescence in situ hybridization revealed the presence of del(17p) in 39.8% of the patients. Patients received a median of 2.0 (range: 0-7) lines of pre-ibrutinib therapy. Median duration of therapy was 8.8 months (range: 0.4-58.0 months). The 1-year PFS and OS rates were 82.2% and 84.6%, respectively, while median PFS time was 30.0 (standard error, 95% confidence interval: 5.1, 20.0-40.0) months and median OS time was 37.9 (3.2, 31.5-44.2) months. Treatment response (complete or partial response), PFS time, and OS time were better with 0-2 lines versus 3-7 lines of prior therapy (p<0.001, p=0.001, and p<0.001, respectively), with ECOG class 0-1 versus class 2-3 (p=0.006, p=0.011, and p=0.001, respectively), and with Rai stage 0-2 versus 3-4 (p=0.002, p=0.001, and p=0.002, respectively). No significant difference was noted in treatment response rates or survival outcome with respect to the presence of comorbidity, bulky disease, or del(17p). While 176 adverse events (AEs) were reported in 74 (54.4%) patients, 46 of those 176 AEs were grade 3-4, including pneumonia (n=12), neutropenia (n=11), anemia (n=5), thrombocytopenia (n=5), and fever (n=5). Conclusion: This real-life analysis confirms the favorable efficacy and safety profile of long-term ibrutinib treatment while emphasizing the potential adverse impacts of poorer ECOG performance status, heavy treatment prior to ibrutinib, and advanced Rai stage on patient compliance, treatment response, and survival outcomes.
