Atrial fibrillation and peripheral arterial disease define MPN patients with very high risk of thrombosis.

Myeloproliferative neoplasms (MPNs) are associated with a high risk of thrombotic and hemorrhagic complications, especially in elderly patients. Atrial fibrillation (AF) and peripheral arterial disease (PAD), also frequently discovered in aging patients, are associated with similar complications. We analysed the incidence and complication rates of AF and PAD in a large cohort of MPN patients. In total, 289/1113 patients (26 %) suffered at least one of these diseases as follows: 179 (16.1 %) with AF alone, 81 with PAD alone (7.3 %) and 29 (2.6 %) with both conditions. Postdiagnosis thrombotic events were observed in 31.3 % of AF patients (p = 0.002, OR = 1.80 [1.23;2.61]), 35.8 % of PAD patients (p = 0.002, OR = 2.21[1.31;3.67]) and 62.1 % of AF/PAD patients (p < 0.0001, OR = 6.47 [2.83;15.46]) compared to 20.1 % of no-AF/no-PAD patients. Postdiagnosis hemorrhagic events were also identified in 17.9 %, 16 %, 24.1 % and 10.1 % of AF, PAD, AF/PAD, and no-AF/no-PAD patients, respectively (p = 0.003). This significantly higher risk of thrombosis/bleeding was also observed in patients <60 years old. AF and PAD were significant risk factors for both thrombotic and hemorrhagic risks in multivariate analysis. We identified AF and PAD as criteria for high risk of thrombosis, hemorrhage, and death, emphasizing the interest in early detection and efficient treatment of these conditions.

Differences between aquagenic and non-aquagenic pruritus in myeloproliferative neoplasms: An observational study of 500 patients.

BACKGROUND: Pruritus is a frequent symptom experienced by patients with myeloproliferative neoplasms (MPN). Aquagenic pruritus (AP) is the most common type. The Myeloproliferative Neoplasm-Symptom Assessment Form Total Symptom Score (MPN-SAF TSS) self-report questionnaires were distributed to MPN patients before consultations. OBJECTIVES: The aim of this study was to assess clinical incidence (phenotypical evolution and response to treatment) of pruritus, especially AP, in MPN patients during their follow-ups. PATIENTS AND METHODS: We collected 1444 questionnaires from 504 patients [54.4% essential thrombocythaemia (ET) patients, 37.7% polycythaemia vera (PV) patients, and 7.9% primary myelofibrosis (PMF) patients]. RESULTS: Pruritus was reported by 49.8% of the patients, including 44.6% of AP patients, regardless of type of MPN or driver mutations. Patients suffering from pruritus were more symptomatic and had a higher rate of evolution into myelofibrosis/acute myeloid leukaemia (19.5% vs. 9.1%, OR = 2.42 [1.39; 4.32], p = 0.0009) than MPN patients without pruritus. Patients with AP had the highest pruritus intensity values (p = 0.008) and a higher rate of evolution (25.9% vs. 14.4%, p = 0.025, OR = 2.07) than patients with non-AP. Disappearance of pruritus was observed in only 16.7% of AP cases, compared to 31.7% of cases with other types of pruritus (p < 0.0001). Ruxolitinib and hydroxyurea were the most effective drugs to reduce AP intensity. CONCLUSIONS: In this study, we demonstrate the global incidence of pruritus across all MPN. Pruritus, especially AP, which is a major constitutional symptom observed in MPN, should be assessed in all MPN patients due to higher symptom burden and higher risk of evolution.

Toxicities from chemotherapy administered in an outpatient department occur mostly when patients return home. Support treatment prescriptions are given to them in order to prevent or limit these toxicities. The cancer plans also specify the need for collaboration between the city and the hospital. In this sense, it is interesting to take stock of the knowledge of private nurses caring for these patients and to identify their expectations.
