ALLiance for sEcondary PREvention after an acute coronary syndrome. The ALLEPRE trial: A multicenter fully nurse-coordinated intensive intervention program.

The main objective of cardiovascular disease prevention is to reduce morbidity and mortality by promoting a healthy lifestyle, reducing risk factors, and improving adherence to medications. Secondary prevention after an acute coronary syndrome has proved to be effective in reducing new cardiovascular events, but its limited use in everyday clinical practice suggests that there is considerable room for improvement. The short-term results of evidence-based studies of nurse-coordinated secondary prevention programs have been positive, but there is a lack of long-term outcome data. The Alliance for the Secondary Prevention of Cardiovascular Disease in the Emilia-Romagna region (ALLEPRE) is a multicenter, randomized, controlled trial designed to compare the effects of a structured nurse-coordinated intensive intervention on long-term outcomes and risk profiles after an acute coronary syndrome with those of the standard of care. All of the patients randomized to the intervention group take part in 9 one-to-one sessions with an experienced nurse from the participating centers with the aim at promoting healthy lifestyles, reducing risk factors, and increasing adherence to medication over a mean period of 5 years. The primary clinical end point is the reduction in the risk of the 5-year occurrence of major adverse events (a composite of cardiovascular mortality, nonfatal reinfarction, and nonfatal stroke). The primary surrogate end point is the achievement of prespecified targets relating to classical risk factors, lifestyle modifications, and adherence to pharmacological therapy after 2 years of follow-up. Coronary heart disease is a chronic degenerative disease, and patients who recover from an acute coronary syndrome (ACS) are at high risk of developing recurrent events.1 Although secondary prevention measures have proved to be effective and are strongly recommended by all of the international guidelines,2., 3. the 4 EUROASPIRE surveys4., 5., 6., 7., 8. showed that there was still a high prevalence of conventional risk factors, that secondary prevention measures were inadequately implemented, and that their main goals were often not reached. In addition, there were considerable discrepancy in secondary prevention practices between centers and countries, and a widespread underuse of cardiac prevention and rehabilitation programs despite their demonstrated effectiveness in reducing cardiovascular risk over time.9., 10. Over the last 10 years, nurses have been increasingly involved in successful cardiovascular risk management,11., 12., 13. but although this has improved levels of cardiovascular risk, no clear reduction in hard end points such as major cardiovascular adverse events and mortality has been demonstrated.10 The aim of the ALLEPRE trial is to evaluate the benefit of a homogeneous, structured, secondary prevention intervention program, fully coordinated by nurses from in- and outpatient clinics, in terms of cardiovascular risk profiles and major clinical events in ACS patients living in the large Emilia-Romagna region of Italy.

Probable tirofiban-induced thrombotic microangiopathy after stent thrombosis: a case report.

Background: Glycoprotein (GP) IIb-IIIa inhibitors are antithrombotic drugs used in selected patients during and after percutaneous coronary interventions (PCIs), usually as a bail-out in the setting of no-reflow or thrombotic complications. A notorious life-threatening adverse effect of this drug class is immune-mediated drug-induced thrombocytopenia (DITP). Thrombotic microangiopathy (TMA) induced by GP IIb-IIIa inhibitors has never been reported. Case summary: A 72-year-old woman admitted for anterior myocardial infarction treated with primary PCI and stent implantation underwent a first tirofiban infusion as a bail-out strategy. After a new procedure for stent thrombosis, she received a second tirofiban infusion and developed sudden severe thrombocytopenia (platelet count <20 000/µL). Tirofiban was stopped but no observed increase in platelet count. Acute kidney injury due to renal ischaemia and left ventricular thrombosis followed. Unexpectedly, evidence for haemolysis and schistocytosis at peripheral blood smear prompted a diagnosis of TMA. Plasma exchange was immediately started with evidence for initial increase in platelet count, but the patient died due to sudden haemodynamic and respiratory deterioration. Discussion: Tirofiban is known to rarely cause immune-dependent DITP. However, it has never been associated with TMA. This case report not only describes the first case of probable tirofiban-induced TMA, but also highlights the importance of a systematic approach to severe thrombocytopenia, even in the setting of low platelet count from a known DITP-related drug. Treatment of TMA in the difficult context of recent myocardial infarction and stent thrombosis requires a complex interplay between cardiologist, haematologist, transfusionist, and nephrologist, carefully balancing thrombotic and haemorrhagic risk.

Sonographic Features of Onychopapilloma: A Single Center Retrospective Observational Study.

(1) Background: Onychopapilloma is a benign tumor of the nail bed and distal matrix. which usually manifests as monodactylous longitudinal eryhtronychia associated with subungual hyperkeratosis. The impossibility to rule out a malignant neoplasm is an indication for surgical excision and histological examination. Our aim is to report and describe the ultrasonographic features of onychopapilloma. (2) Methods: we conducted a retrospective analysis of patients with a histological diagnosis of onychopapilloma who underwent ultrasonographic examination in our Dermatology Unit from January 2019 to December 2021. (3) Results: Six patients were enrolled. Erythronychia, melanonychia, and splinter hemorrhages were the main dermoscopical findings. Ultrasonography detected nail bed dishomogeneity in three patients (50%) and a distal hyperechoic mass (5 patients, 83.3%). Color Doppler imaging did not show vascular flow in any of the cases. (4) Conclusions: the detection of a subungual distal non-vascularized hyperechoic mass by US, together with classical onychopapilloma clinical features, supports the diagnosis, especially in those patients who were unable to perform excisional biopsy.

Sonidegib in Locally Advanced Basal Cell Carcinoma: A Monocentric Retrospective Experience and a Review of Published Real-Life Data.

Basal cell carcinoma (BCC) represents the most common skin cancer and locally advanced BCC (laBCC) refers to an aggressive, large, infiltrative BCC that cannot be treated by surgery or radiotherapy. Sonidegib is a Hedghehog inhibitor (HHi) indicated for laBCC. This is a monocentric retrospective real-life study of laBCCs receiving Sonidegib treatment. Although Sonidegib is widely used, since its approval by Food and Drug Administration in 2015, only a limited number of real-life experiences have been reported. Eleven patients, including four patients diagnosed with Basal Cell Naevus syndrome, received treatment with Sonidegib for laBCCs. Seven (63.6%) patients experienced adverse events (AEs) but only three had to discontinue treatment and were therefore excluded from the following results. Four patients (50%) achieved complete clinical remission (CR); in all cases the remission was confirmed by biopsy. Partial response (PR) was found in three patients out of eight (37.5%). One patient out of eight (12.5%) showed a steady disease (SD). None of the patients showed signs of progression during treatment with HHi. Sonidegib showed the same efficacy in treating laBCCs as already seen in trials. All four patients suffering from Basal Cell Naevus syndrome achieved disease control by being treated with Sonidegib. Consequently, we strongly advise the joint management of laBCCs through a multidisciplinary team whenever feasible.

Clinical, Dermoscopic, Ultrasonographic, and Histopathologic Correlations in Kaposi's Sarcoma Lesions and Their Differential Diagnoses: A Single-Center Prospective Study.

(1) Background: Kaposi's sarcoma (KS) is an angioproliferative neoplasm typically appearing as angiomatous patches, plaques, and/or nodules on the skin. Dermoscopy and ultrasonography have been suggested as an aid in the diagnosis of KS, but there is little evidence in the literature, especially regarding its possible differential diagnoses. Our aim is to describe and compare the clinical, dermoscopic, and ultrasonographic features of KS and KS-like lesions. (2) Methods: we conducted a prospective study on 25 consecutive patients who were first referred to our tertiary care center from January to May 2021 for a possible KS. (3) Results: 41 cutaneous lesions were examined by means of dermoscopy, Doppler ultrasonography, and pathology, 32 of which were KS-related, while the remaining 9 were lesions with clinical resemblance to KS. On dermoscopy, a purplish-red pigmentation, scaly surface, and the collarette sign were the most common features among KS lesions (81.3%, 46.9%, and 28.1%, respectively). On US, all 9 KS plaques and 21 KS nodules presented a hypoechoic image. Dermoscopic and Doppler ultrasonographic findings of KS-like lesions, such as cherry angioma, venous lake, glomus tumor, pyogenic granuloma, and angiosarcoma were also analyzed. (4) Conclusions: dermoscopy and Doppler ultrasonography can be useful to better assess the features of KS lesions and in diagnosing equivocal KS-like lesions.

Combination of Platelet expression of PKCepsilon and cardiac troponin-I for early diagnosis of chest pain patients in the emergency department.

A rapid differential diagnosis of the clinical conditions underlying chest pain is a relevant clinical issue. Specifically, a fast rule-in or -out of acute myocardial infarction (AMI) is mandatory to improve diagnostic outcome and cost-effectiveness of patient management. We demonstrated that Protein Kinase C (PKC) epsilon is selectively expressed by platelets from AMI patients, accounting for increased platelet activation. Thus, we hypothesized that PKCepsilon-expressing platelets may represent a pathophysiological marker of AMI that could be utilized in combination with troponin-I, the conventional marker of cardiac injury, to add diagnostic information in chest pain workup. In 94 chest pain patients consecutively admitted to Parma University Hospital, we tested the diagnostic performance of flow-cytometric detection of PKCepsilon expressing platelets in discriminating AMI vs. non-AMI conditions. We demonstrated that PKCepsilon-expressing platelets were significantly higher in patients with AMI. Flow cytometry detection of PKCepsilon-expressing platelets showed high sensitivity and specificity (87.5% and 84.4%, respectively) and good diagnostic accuracy (AUC: 0.875). The combination of PKCepsilon expressing platelets and cardiac troponin clearly discriminates patients with 100% and 0% of probability to be affected by AMI. Overall, we highlighted a dual marker strategy potentially useful for a rapid rule-in or -out of myocardial infarction in chest pain patients.

Internal Jugular Vein Complete Thrombosis After Dual Chamber Pacemaker Implant.

Venous thrombosis after pacemaker implant is a known, although often underrecognized condition that can challenge system revision or upgrading, leading occasionally to thromboembolic complications. Several factors are considered to promote thrombus formation. Among them, alteration of blood flow mechanics due to the presence of catheters in the vessel lumen may itself play a pivotal role. Hereby we present the case of a 65-year old men who underwent a dual-chamber pacemaker implant in another institute for sick sinus syndrome by means of left cephalic venous access. About two months later he started experiencing neck swelling, pain and dysphagia. Six months later, ultrasonography and CT-scan revealed complete jugular vein thrombosis caused by a lead loop at the level of the left subclavian vein. Of note, thrombosis occurred despite proper oral anticoagulation with warfarin undertaken for coexisting atrial fibrillation. It's important to keep in mind this possible complication of pacemaker implant to allow for early diagnosis and better treatment chances. This case report is an example of how proximal catheter displacement may promote thrombus formation, probably by affecting blood flow mechanics, even in spite of proper oral anticoagulation.

Hypoglicemia related to big Haemangiopericitoma: a difficult diagnostic definition.

We describe the case of a 91 years old woman admitted to our department for dyspnea associated with drowsiness. At the admission to the Emergency Room the patient stay in a comatose state and blood tests performed showing severe hypoglycemia (38 mg/dl at admission in non diabetic patient). Anamnestic history: multifactorial anemia; frequent hospitalizations for heart failure; AMI treated with stenting; in 1986 Haemangiopericytoma resection in the right iliac region; in 2006 palliative surgery for recurrence with residual mass. Blood tests showed lower levels of insulin and normal C- peptide serum concentration in correspondence of low glucose concentration (in relation to continuous and adequate parenteral nutrition), IGF 1 and GH level was respectively suppressed (IGF1=47 ng/ml whit normal range 97-331 ng/ml) and normal/low (GH 0.43 uUI/mL whit normal range 0.06-14.00 uUI/mL).Therefore hypoglycemia appeared related to paraneoplastic production of IGF -2.

Multi-dimensional nursing form: a novel means of approaching nurse-led secondary cardiology prevention.

BACKGROUND AND AIM: Secondary prevention after an acute coronary syndrome (ACS) has proved to be effective in patients with coronary heart disease, and is strongly recommended by the international guidelines. However, there is a lack of widespread secondary preventive programmes in real-world clinical practice, even though it has been shown that these can be successfully conducted by nurses. METHOD AND RESULTS: We have designed a multicentre randomised trial involving patients with ACS in which nurses will fully coordinate secondary prevention in the intervention arm using a multidimensional nursing form after attending ad hoc teaching sessions.

Evolution of Framingham cardiovascular risk score in HIV-infected patients initiating EFV- and LPV/r-based HAART in a Latin American cohort.

INTRODUCTION: Epidemiological studies suggest that some antiretroviral drugs may contribute to increase cardiovascular risk in HIV-infected patients. However, data from Latin American countries are limited, as impact of HAART on cardiovascular risk remains understudied. In this context, we aimed to evaluate if 10-year Framingham Cardiovascular Risk Score (FCRS) increases in patients following exposure to EFV- and LPV/r-based HAART in a Latin American cohort. MATERIALS AND METHODS: Retrospective 48-week cohort study. We reviewed clinical charts of randomly selected samples of patients initiating (according to national guidelines) EFV first-line HAART and LPV/r first- or second-line (but first PI-based) HAART assisted at a reference HIV centre in Buenos Aires, Argentina (period 2004-2012). Each patient could only be included in one arm. FCRS was calculated according to National Institutes of Health risk assessment tool (http://cvdrisk.nhlbi.nih.gov/). RESULTS: A total of 357 patients were included: 249 in EFV arm and 108 in LPV/r arm (80 as first line and 28 as second line, but first PI-based HAART). Baseline characteristics (median, interquartile range): age, 38 (33-45) years; male, 247 (69%); viral load, 98200 (20550-306000) copies/mL; CD4 T-cell count, 115 (60-175) cel/µL; total cholesterol, 159 (135-194) mg/dL; HDL: 39 (31-41) mg/dL; LDL: 94 (72-123) mg/dL; current smoker, 29%; on antihypertensive drugs: 14 (4%), diabetic: 4 (1%). Most frequent accompanying nucleoside reverse transcriptase inhibitors (NRTIs) were 3TC (92%) and zidovudine (AZT; 76%). Baseline FCRS was low, moderate and high for 93%, 7% and 0% of patients on EFV arm and 96.7%, 1.7% and 1.7% on LPV/r arm. On EFV arm, an increase in FCRS category (low to moderate or moderate to high) was observed in 1 patient (0.9%) at 24 weeks and 6 (5,6%) at 48 weeks; 5 (4.7%) decreased category. On LPV/r arm no one varied FCRS category at 24 weeks and 2 (3.4%) increased from low to moderate at 48 weeks (no patient decreased FCRS category). Cumulative incidence of overall cardiovascular events was 1.6% on EFV and 1.8% on LPV/r arms respectively. Probability of increasing FCRS category or having a cardiovascular event did not differ between arms at a significance level of 5%. CONCLUSIONS: Probability of increasing FCRS category and cardiovascular events was low and similar in patients exposed to EFV versus LPV/r-based HAART in a Latin American cohort.

Protein kinase C ε expression in platelets from patients with acute myocardial infarction.

OBJECTIVE: Platelets play crucial roles in the pathophysiology of thrombosis and myocardial infarction. Protein kinase C ε (PKCε) is virtually absent in human platelets and its expression is precisely regulated during human megakaryocytic differentiation. On the basis of what is known on the role of platelet PKCε in other species, we hypothesized that platelets from myocardial infarction patients might ectopically express PKCε with a pathophysiological role in the disease. METHODS AND RESULTS: We therefore studied platelet PKCε expression from 24 patients with myocardial infarction, 24 patients with stable coronary artery disease and 24 healthy subjects. Indeed, platelets from myocardial infarction patients expressed PKCε with a significant frequency as compared to both stable coronary artery disease and healthy subjects. PKCε returned negative during patient follow-up. The forced expression of PKCε in normal donor platelets significantly increased their response to adenosine diphosphate-induced activation and adhesion to subendothelial collagen. CONCLUSIONS: Our data suggest that platelet generations produced before the acute event retain PKCε-mRNA that is not down-regulated during terminal megakaryocyte differentiation. Results are discussed in the perspective of peri-infarctual megakaryocytopoiesis as a critical component of myocardial infarction pathophysiology.
