Pancytopenia due to iron deficiency worsened by iron infusion: a case report

<p>Abstract</p> <p>Introduction</p> <p>Iron deficiency anemia is commonly associated with thrombocytosis, although thrombocytopenia has been reported in occasional patients with iron-deficiency anemia. Much less common is the development of thrombocytopenia following replenishment of iron stores.</p> <p>Case Presentation</p> <p>We present the unusual case of a 39 year old African American female Jehovah's Witness who presented with a 10 month history of menorrhagia and pancytopenia. Laboratory investigations confirmed a severe iron deficiency. Since blood transfusion was unacceptable to her, she was started on intravenous iron replacement therapy. This precipitated a sudden drop in both her platelet and white blood cell counts. Histopathological examination of the bone marrow revealed a hypercellular marrow with orderly trilineage hematopoiesis, iron deficiency anemia, granulocytic hyperplasia, and mild megakaryocytic hypoplasia. Both her white blood cell and platelet counts recovered uneventfully with continuing iron supplementation. The possible mechanism for this phenomenon is discussed in this report.</p> <p>Conclusion</p> <p>This case illustrates two rather uncommon associations of a very common problem. Severe iron deficiency anemia may be associated with pancytopenia and iron replacement may cause a transient decline in megakaryopoiesis and leukopoiesis. Severe iron deficiency should be added to the list of conditions leading to thrombocytopenia.</p

Taxane-Platin-Resistant Lung Cancers Co-develop Hypersensitivity to JumonjiC Demethylase Inhibitors

Although non-small cell lung cancer (NSCLC) patients benefit from standard taxane-platin chemotherapy, many relapse, developing drug resistance. We established preclinical taxane-platin-chemoresistance models and identified a 35-gene resistance signature, which was associated with poor recurrence-free survival in neoadjuvant-treated NSCLC patients and included upregulation of the JumonjiC lysine demethylase KDM3B. In fact, multi-drug-resistant cells progressively increased the expression of many JumonjiC demethylases, had altered histone methylation, and, importantly, showed hypersensitivity to JumonjiC inhibitors in vitro and in vivo. Increasing taxane-platin resistance in progressive cell line series was accompanied by progressive sensitization to JIB-04 and GSK-J4. These JumonjiC inhibitors partly reversed deregulated transcriptional programs, prevented the emergence of drug-tolerant colonies from chemo-naive cells, and synergized with standard chemotherapy in vitro and in vivo. Our findings reveal JumonjiC inhibitors as promising therapies for targeting taxane-platin-chemoresistant NSCLCs.Fil: Dalvi, Maithili P.. University of Texas.

Daily Lisinopril vs Placebo for Prevention of Chemoradiation-Induced Pulmonary Distress in Patients With Lung Cancer (Alliance MC1221):A Pilot Double-Blind Randomized Trial

Purpose: Chemoradiation (CRT) is an integral treatment modality for patients with locally advanced lung cancer. It has been hypothesized that current use of an angiotensin-converting enzyme inhibitor during CRT may be protective for treatment-related lung damage and pneumonitis. Methods and Materials: We conducted a pilot, double-blind, placebo-controlled, randomized trial. Study-eligible patients receiving curative thoracic radiation therapy (RT) were randomly assigned to 20 mg of lisinopril or placebo once daily during and up to 3 months after RT. All patients received concurrent chemotherapy. The primary endpoint was adverse event profiling. Multiple patient-reported outcome (PRO) surveys, including the Lung Cancer Symptom Scale, Function Assessment of Cancer TherapyeLung, and the European Organisation for Research and Treatment of Cancer Lung Cancer Questionnaire, were applied with a symptom experience questionnaire. Exploratory comparative statistics were used to detect differences between arms with c 2 and Kruskal-Wallis testing. Results: Five institutions enrolled 23 patients. However, accrual was less than expected. Eleven and 12 patients were in the placebo and lisinopril arms, respectively (mean age, 63.5 years; male, 62%). Baseline characteristics were balanced. Eighteen patients (86%) were former or current smokers. The primary endpoint was met; neither arm had grade 3 or higher hypotension, acute kidney injury, allergic reaction (medication-induced cough), or anaphylaxis (medication-related angioedema). Few PRO measures suggested that compared with the placebo arm, patients receiving lisinopril had less cough, less shortness of breath, fewer symptoms from lung cancer, less dyspnea with both walking and climbing stairs, and better overall quality of life (for all, P Conclusions: Although underpowered because of low accrual, our results suggest that there was a clinical signal for safetydand possibly beneficial by limited PRO measuresdin concurrently administering lisinopril during thoracic CRT to mitigate or prevent RT-induced pulmonary distress. Our results showed that a definitive, larger-scale, randomized phase 3 trial is needed in the future. (C) 2018 Published by Elsevier Inc

Between the legacy of nation-state and forces of globalisation : Turkey’s management of mixed migration flows

Turkey, at the crossroads of Europe, Middle East and Asia, has confronted with mounting pressures of mixed migration flows in recent decades. This paper aims to explore Turkey’s contemporary approach to migration management by focusing on the adoption of the country’s first comprehensive immigration law (Law on Foreigners and International Protection) and the signing of the readmission agreement with the European Union in 2013. This incorporates an analysis of both policy continuities and changes in migration management in Turkey, while also providing an understanding of the interplay between internal and external factors, namely internationalisation and Europeanisation processes and the responsiveness of domestic actors to such pressures. The paper argues that migration policies driven solely by state-centric concerns are becoming increasingly inefficient in responding to the challenges caused by interlinked pressures of globalisation and multi-layered migratory flows. As Turkey’s role as a transit and receiving country grows, issues of international migration, and irregular migration in particular, are becoming dynamic topics in defining its role in a globalised world and as well as the trajectory of its relations with the EU
