Sacubitril/Valsartan to Treat Heart Failure in a Patient with Relapsing Hairy Cell Leukaemia: Case Report.

Experience with angiotensin-receptor neprilysin inhibitors (ARNI) in oncologic patients with heart failure (HF) is limited. We report a case of ARNI started as first-choice therapy in a patient with relapsing hairy cell leukaemia (HCL) and HF with depressed left ventricular ejection fraction (LVEF). A middle-aged male, previously treated with rituximab for HCL, was scheduled for cardiologic screening before starting a new antineoplastic therapy for cancer relapse. The patient had symptomatic HF with reduced LVEF and high NT-proBNP levels. In this patient, early ARNI treatment was well tolerated and produced a rapid and durable improvement of symptoms, LVEF and NT-proBNP levels. Consequently, the oncologic team could start an experimental treatment with obinutuzumab, with complete HCL remission. In conclusion, in this patient with HCL and HF, ARNI therapy was safe and effective, contributing to undelayed cancer treatment.

Variant angina associated with coronary artery endothelial dysfunction and myocardial bridge: a case report and review of the literature.

The association of variant angina (VA) and myocardial bridges is a rare finding. We describe a case of VA with recurrent coronary spasm triggered by different stimuli at the site of a myocardial bridge. The interplay of endothelial dysfunction, coronary vasoconstriction and myocardial bridging was detected by intracoronary acetylcholine test and IVUS. We speculate that mechanical stimulation at the bridge site caused endothelial dysfunction and enhanced local susceptibility to vasoconstrictor stimuli. Variant angina should always be suspected in cases of ST-elevation acute coronary syndrome without any significant angiographic coronary stenosis.

[Prognostic value of serum beta2-microglobulin in multiple myeloma]. / Utilità prognostica della determinazione della beta2-microglobulina sierica nel mieloma multiplo.

We have analysed a series of 96 patients with multiple myeloma (MM) to the purpose to verify the prognostic meaning of the beta2-microglobulin (B2M) and the validity of the staging systems proposed by Bataille and Jacobson who use the B2M respectively associated to the serum C-reactive protein (CRP) and to the serum albumin. In our series of patients the serum level of B2M at the diagnosis was directly correlated with the myelomatous cellular mass. We have found besides an inverse correlation between B2M and survival. Also the serum level of CRP was inversely correlated with the survival, while a direct correlation was found between the serum albumin and the survival: ipoalbuminemia was confirmed as a predictive index of short survival. Staging our patients with MM according to the proposal of Bataille, we identified also in our series three prognostic groups with different median survival: respectively 72, 40 and 18 months. Applying finally the staging proposal of Jacobson to our series, four stages were individualized, with median survival respectively of 70, 52, 26 and 10 months. We confirm the prognostic value of the B2M in MM.
