A practical guide to managing hypertension, hyperlipidemia, and hyperglycemia in patients with chronic myeloid leukemia

Semaglutide treatment for type 2 diabetes in a patient with chronic myeloid leukemia: A case report and review of the literature

Background

Comorbid type 2 diabetes mellitus (T2DM), severe obesity, and chronic myeloid leukemia (CML) present therapeutic challenges, especially given the limited data on glucagon-like peptide-1 (GLP-1) receptor agonists in this setting.

Methods

We describe a 33-year-old female with poorly controlled T2DM (HbA1c 10.7%), severe obesity (BMI 47.05 kg/m2), and stable CML on tyrosine kinase inhibitor therapy. She received once-weekly semaglutide (0.5-1.5 mg) for 6 months, alongside insulin glargine and dapagliflozin/metformin. Clinical, biochemical, and molecular parameters were monitored.

Results

After 6 months, her HbA1c declined from 10.7 to 5.5%, fasting plasma glucose from 16.2 to 5.3 mmol/L, and body weight decreased by 18 kg. Lipid parameters improved, and molecular analysis confirmed continued CML remission (undetectable BCR-ABL1). The patient experienced only mild, transient gastrointestinal side effects.

Conclusion

In this complex case, semaglutide proved safe and effective for achieving glycemic control and weight reduction without compromising CML stability. These findings suggest that GLP-1 receptor agonists may be a viable therapeutic option for patients with coexisting T2DM, severe obesity, and stable CML, warranting further investigation in broader populations.

Caught in the Crossfire: Unmasking the Silent Renal Threats of Tyrosine Kinase Inhibitors in Chronic Myeloid Leukemia

BACKGROUND

Renal adverse drug reactions (ADRs) associated with tyrosine kinase inhibitors (TKIs) in the treatment of chronic myeloid leukemia (CML) are relatively rare, and there is currently no standardized protocol for their management. Therefore, this study aimed to summarize renal ADRs related to TKIs use in CML and propose an evidence-based approach to monitor and manage these ADRs.

METHODS

A systematic literature review was performed to identify renal ADRs associated with TKIs in CML. Two authors screened the search results and extracted data from 37 eligible studies. These findings were then used to develop a scheme for clinicians to monitor and manage these ADRs.

RESULTS

Overall, imatinib seemed to be significantly linked to renal adverse events compared to other TKIs, and switching to dasatinib or nilotinib significantly improved renal function. Similar events were reported with bosutinib, although they were not statistically significant. However, most of the renal events reported on dasatinib were described as nephrotic syndrome that resolved with switching to imatinib. Few cases were reported with nilotinib that described tumor lysis syndrome (TLS)-related kidney injury.

CONCLUSIONS

Recommendations include monitoring for progressive decline in the estimated glomerular filtration rate with imatinib, nephrotic syndrome with dasatinib, and TLS with nilotinib. Additionally, holding the offending TKI and managing renal ADRs according to local guidelines were adopted more frequently than reducing the TKI dose.

Mitochondrial-related drug resistance lncRNAs as prognostic biomarkers in laryngeal squamous cell carcinoma

Laryngeal squamous cell carcinoma (LSCC) is a common malignant tumor of the head and neck that significantly impacts patients' quality of life, with chemotherapy resistance notably affecting prognosis. This study aims to identify prognostic biomarkers to optimize treatment strategies for LSCC. Using data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO), combined with mitochondrial gene database analysis, we identified mitochondrial lncRNAs associated with drug resistance genes. Key long non-coding RNAs (lncRNAs) were selected through univariate Cox regression and Lasso regression, and a multivariate Cox regression model was constructed to predict prognosis. We further analyzed the differences in immune function and biological pathway enrichment between high- and low-risk groups, developed a nomogram, and compared drug sensitivity. Results showed that the prognostic model based on seven mitochondrial lncRNAs could serve as an independent prognostic factor, with Area Under the Curve (AUC) values of 0.746, 0.827, and 0.771 at 1, 3, and 5 years, respectively, outperforming some existing models, demonstrating high predictive performance. Significant differences were observed in immune function and drug sensitivity between the high- and low-risk groups. The risk prediction model incorporating seven drug resistance-related mitochondrial lncRNAs can accurately and independently predict the prognosis of LSCC patients.

Underlying mechanisms and management strategies for regorafenib-induced toxicity in hepatocellular carcinoma

INTRODUCTION

Hepatocellular carcinoma (HCC) accounts for 85% of liver cancer cases and is the third leading cause of cancer death. Regorafenib is a multi-target inhibitor that dramatically prolongs progression-free survival in HCC patients who have failed sorafenib therapy. However, one of the primary factors limiting regorafenib's clinical utilization is toxicity. Using Clinical Trials.gov and PubMed, we gathered clinical data on regorafenib and conducted a extensive analysis of the medication's adverse reactions and mechanisms. Next, we suggested suitable management techniques to improve regorafenib's effectiveness.

AREAS COVERED

We have reviewed the mechanisms by which regorafenib-induced toxicity occurs and general management strategies through clinical trials of regorafenib. Furthermore, by examining the literature on regorafenib and other tyrosine kinase inhibition, we summarized the mechanics of the onset of regorafenib toxicity and mechanism-based intervention strategies by reviewing the literature related to regorafenib and other tyrosine kinase inhibition.

EXPERT OPINION

One of the primary factors restricting regorafenib's clinical utilization and combination therapy is its toxicity reactions. To optimize regorafenib treatment regimens, it is especially important to further understand the specific toxicity mechanisms of regorafenib as a multi-kinase inhibitor.

Chronic Myeloid Leukemia in Adolescents and Young Adults: Clinicopathological Variables and Outcomes

INTRODUCTION

Adolescents and young adults (AYAs) diagnosed with chronic myeloid leukemia (CML) constitute a significant demographic group, particularly in regions with youthful populations like Qatar. Despite the global median age of CML diagnosis being 65 years, Qatar's age distribution reflects a younger cohort. This study investigates whether AYAs with CML exhibit distinct clinicopathological characteristics or outcomes compared to older age groups.

METHODS

A total of 224 CML patients were enrolled, including 114 AYAs (defined as ages 15 through 39). Demographic and clinical parameters, including gender, BMI, BCR-ABL1 transcript type, white blood cell (WBC) count, hemoglobin level, platelet count, and spleen size, were compared between AYAs and older patients. Prognostic scoring systems (Sokal, Hasford, EUTOS, and ELTS) and molecular response rates (MMR and DMR) were also evaluated.

RESULTS

AYAs demonstrated higher WBC counts at diagnosis (median 142.3 vs. 120; p = 0.037) and lower hemoglobin levels (10.5 vs. 11.40; p = 0.004) compared to older patients. Spleen size was significantly larger in AYAs (18.8 vs. 15.5; p = 0.001). While AYAs showed better prognostic scores by Sokal and Hasford criteria, EUTOS and ELTS scores indicated comparable risk stratification. However, AYAs exhibited lower rates of MMR (56.7 vs. 73.4%; p = 0.016) and achieved MMR at a slower pace (median time 130 vs. 103 months; p = 0.064). Similarly, the percentage of DMR was lower in AYAs (37.1 vs. 46.8%; p = 0.175).

CONCLUSION

Despite their younger age, AYAs with CML displayed poorer prognoses compared to older patients. These findings underscore the importance of tailored management strategies for AYAs with CML to optimize outcomes in this distinct patient population.

KEY POINT

AYAs are underrepresented in CML studies and risk scores, so this is the focus of this study.

Myocardial Infarction in Chronic Myeloid Leukemia: Results from the Nationwide Readmission Database

INTRODUCTION

Chronic myeloid leukemia (CML) is a hematological malignancy with an excellent prognostic outcome. After the advancements in CML treatment and the introduction of different tyrosine kinase inhibitors (TKIs), the life expectancy of CML patients has become equivalent to that of the general population. As a result, coronary artery disease is anticipated to be the leading cause of death among CML patients. Moreover, TKI use is associated with a risk of endothelial dysfunction, thrombosis, and cardiovascular events, including myocardial infarction. In this study, we compare the outcomes of percutaneous coronary intervention (PCI) in patients with CML to their matched non-CML counterparts.

METHOD

This is a retrospective cohort study using the Nationwide Readmission Database from January 2016 to December 2020. Adults with or without CML hospitalized for acute myocardial infarction and underwent PCI were included. The patients were identified using ICD-10 codes. The primary outcomes were in-hospital mortality and 30-day readmission rates. The secondary outcomes were PCI complications rates.

RESULTS

Out of 2,727,619 patients with myocardial infarction, 2,124 CML patients were identified. A total of 888 CML patients underwent PCI. CML patients were significantly older (mean age: 68.34 ± 11.14 vs. 64.40 ± 12.61 years, p < 0.001) than non-CML patients without a difference in sex distribution. Hypertension (85.45% vs. 78.64%), diabetes (45.48% vs. 37.29), stroke (11.84% vs. 7.78) at baseline were significantly higher in the CML group. Prior myocardial infarction events (20.51% vs. 15.17%) and prior PCI procedure (24.47% vs. 16.89%) were significantly higher in the CML group. CML patients had a significantly longer hospital stay (4.66 ± 4.40 vs. 3.75 ± 4.62 days, p = 0.001). The primary outcomes did not differ between the comparison groups. The risk of post-PCI complications did not differ between the comparison groups in the propensity matched analysis except for coronary artery dissection (odds ratio [OR]: 0.10; 95% confidence interval [CI]: 0.02-0.65, p = 0.016) and ischemic stroke (OR: 0.35; 95% CI: 0.14-0.93, p = 0.034) which were lower in the CML group.

CONCLUSION

This analysis showed no statistically significant difference in mortality, 30-day readmission, and post PCI complications rates between CML and non-CML patients. However, interestingly, CML patients may experience lower coronary artery dissection and ischemic stroke events than those without CML diagnosis.

Male Fertility and Fatherhood in Chronic Myeloid Leukemia: Current Understanding and Future Perspectives

Chronic myeloid leukemia (CML), while traditionally a disease of the elderly, has recently risen in incidence among younger patients. Hence, fertility concerns have emerged considering the disease process and treatments, especially with the current scarce and conflicting recommendations. This review explores the impact of CML treatments including the first-line tyrosine kinase inhibitors (TKIs) and other treatments on male fertility in chronic myeloid leukemia (CML) patients. The aim of this review was to compile the available evidence on male fertility to ultimately tailor treatment plans for male CML patients for whom fertility and future chances for conception pose a concern. The data available on the conventional and newer TKIs to address fertility concerns were reviewed, particularly the potential long- and short-term effects. Also, the possible side effects on subsequent generations were a crucial focus point of this review to reach a more comprehensive CML management approach. We found and compared the evidence on TKIs approved to treat CML. We also reported the effects of hydroxyurea, interferon, and transplantation, which are considered second-line treatments. Our findings suggest that these drugs might have an undiscovered effect on fertility. More research with larger sample sizes and longer follow-up periods is essential to solidify our understanding of these effects.

Safety and Efficacy of Asciminib in Chronic Myeloid Leukemia Patient with Chronic Kidney Diseases: A Case Report

Introduction

Chronic myeloid leukemia (CML) is characterized by the presence of the BCR::ABL1 fusion gene, and the advent of tyrosine kinase inhibitors (TKIs) has revolutionized its therapeutic landscape. Asciminib, a STAMP inhibitor, emerges as a promising option for patients unresponsive or intolerant to multiple conventional TKIs. However, the safety and efficacy of asciminib in individuals with chronic kidney disease remain understudied.

Case Presentation

In this report, we detail the case of a 62-year-old patient with CML and stage 3 chronic kidney disease, who faced intolerance to traditional TKIs primarily due to fluid retention. The transition to asciminib therapy resulted in a profound molecular response and did not exacerbate renal function, effectively addressing the fluid retention issue.

Conclusion

This case highlights the potential of asciminib as a viable therapeutic alternative for CML patients with chronic kidney disease, particularly those intolerant to standard TKIs. Further research is warranted to establish the broader safety and efficacy profile of asciminib in this patient population.

Obstructive Sleep Apnea Does Not Exclude Polycythemia Vera: A Case Report

Introduction

Polycythemia vera (PV) is one of the myeloproliferative neoplasms (MPN) diagnosed by World Health Organization (WHO) criteria 2016, which requires the presence of 3 major criteria: high hemoglobin/hematocrit, bone marrow findings, and Janus Kinase 2 (JAK2) mutation or two major and one minor criteria, including erythropoietin (EPO) level. However, in clinical practice, difficulties in diagnosis can arise as it may be masked by secondary causes for erythrocytosis such as smoking or obstructive sleep apnea (OSA).

Case Presentation

Here, we report a 55-year-old gentleman, morbidly obese with OSA on home continuous positive airway pressure (CPAP) machine, who was incidentally found to have polycythemia. Further evaluation confirmed the diagnosis of PV.

Conclusion

PV can be masked by the assumption of secondary polycythemia based on history. This underscores the importance of screening such cohort through JAK2 and EPO testing to avoid missing PV.

Warm Autoimmune Hemolytic Anemia as First Presentation of Chronic Myeloid Leukemia: A Case Report

Introduction

Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm characterized by the Philadelphia chromosome and uncontrolled granulocyte production. While autoimmune hemolytic anemia (AIHA) is commonly associated with lymphoproliferative disorders such as chronic lymphocytic leukemia, its occurrence in CML is rare, with only a few documented cases. Here, we report a case of concurrent chronic-phase CML and AIHA.

Case Presentation

We present a 34-year-old female diagnosed with warm AIHA as the first presentation of CML. Diagnostic workup, including peripheral smear, revealed hemolysis with elevated lactate dehydrogenase and a positive direct antiglobulin test (DAT), along with a positive Philadelphia chromosome, confirming CML. Steroid therapy successfully managed the AIHA, leading to normalization of hemoglobin levels and subsequent tapering and discontinuation of steroids.

Conclusion

While AIHA is a rare cause of anemia in CML, it should be considered during anemia evaluation, particularly in cases of CML relapse.

A practical guide to managing cardiopulmonary toxicities of tyrosine kinase inhibitors in chronic myeloid leukemia

Tyrosine kinase inhibitors (TKIs) have revolutionized the treatment of chronic myeloid leukemia (CML) but their use was associated with a range of serious cardiopulmonary toxicities including vascular adverse events, QT prolongation, heart failure, pleural effusion, and pulmonary arterial hypertension. Dedicated clinical management guidelines for TKI-induced toxicities are not available. This review aims to discuss TKI-associated cardiopulmonary toxicities and proposes a practical guide for their management.
