Current lipid lowering treatment and attainment of LDL targets recommended by ESC/EAS guidelines in very high-risk patients with established atherosclerotic cardiovascular disease: Insights from the START registry.

BACKGROUND: Current European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guidelines for the management of dyslipidemias have further reduced low density lipoprotein-cholesterol (LDL-C) targets, as compared to the guidelines released in 2016. These targets are particularly restraining for patients at very high risk (VHR). METHODS: Using the data from a nationwide, prospective registry on patients with established atherosclerotic cardiovascular disease (ASCVD), we sought to assess: 1) the contemporary use of conventional cholesterol-lowering therapies and the achievement of LDL-C goals according to previous and current ESC guidelines in subjects at VHR; 2) the proportion of VHR patients potentially eligible for proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i) treatment. RESULTS: Among the 5053 patients with data available, 4751 (94.0%) were deemed as VHR. Among these patients, the mean LDL-C levels were 62.4 ± 47.7 mg/dl at enrollment. A high dose of statin was used in 54.9%, while the association of high dose statin and ezetimibe was prescribed in 4.8% of VHR patients. A target level of LDL-C < 70 mg/dl recommended by 2016 ESC guidelines was reached by 58.1%, while a target of <55 mg/dl and LDL-C reduction ≥50% recommended by 2019 ESC guidelines, would be reached by 3.2% of patients at VHR. Accordingly, 9.4% and 1.4% of VHR patients would be eligible for PCSK9i according to ESC guidelines and Italian regulations, respectively. CONCLUSIONS: In VHR patients enrolled in this large cohort of established ASCVD managed by cardiologists, the lipid management and LDL-C targets attainment is largely suboptimal.

Cardiac and Neuromuscular Features of Patients With LMNA-Related Cardiomyopathy.

Background: Mutations in the LMNA (lamin A/C) gene have been associated with neuromuscular and cardiac manifestations, but the clinical implications of these signs are not well understood. Objective: To learn more about the natural history of LMNA-related disease. Design: Observational study. Setting: 13 clinical centers in Italy from 2000 through 2018. Patients: 164 carriers of an LMNA mutation. Measurements: Detailed cardiologic and neurologic evaluation at study enrollment and for a median of 10 years of follow-up. Results: The median age at enrollment was 38 years, and 51% of participants were female. Neuromuscular manifestations preceded cardiac signs by a median of 11 years, but by the end of follow-up, 90% of the patients had electrical heart disease followed by structural heart disease. Overall, 10 patients (6%) died, 14 (9%) received a heart transplant, and 32 (20%) had malignant ventricular arrhythmias. Fifteen patients had gait loss, and 6 had respiratory failure. Atrial fibrillation and second- and third-degree atrioventricular block were observed, respectively, in 56% and 51% of patients with combined cardiac and neuromuscular manifestations and 37% and 33% of those with heart disease only. Limitations: Some of the data were collected retrospectively. Neuromuscular manifestations were more frequent in this analysis than in previous studies. Conclusion: Many patients with an LMNA mutation have neurologic symptoms by their 30s and develop progressive cardiac manifestations during the next decade. A substantial proportion of these patients will have life-threatening neurologic or cardiologic conditions. Primary Funding Source: None.

Rotavirus genotypes in sewage treatment plants and in children hospitalized with acute diarrhea in Italy in 2010 and 2011.

Although the molecular surveillance network RotaNet-Italy provides useful nationwide data on rotaviruses causing severe acute gastroenteritis in children in Italy, scarce information is available on rotavirus circulation in the general Italian population, including adults with mild or asymptomatic infection. We investigated the genotypes of rotaviruses present in urban wastewaters and compared them with those of viral strains from clinical pediatric cases. During 2010 and 2011, 285 sewage samples from 4 Italian cities were tested by reverse transcription-PCRs (RT-PCRs) specific for rotavirus VP7 and VP4 genes. Rotavirus was detected in 172 (60.4%) samples, 26 of which contained multiple rotavirus G (VP7 gene) genotypes, for a total of 198 G types. Thirty-two samples also contained multiple P (VP4 gene) genotypes, yielding 204 P types in 172 samples. Genotype G1 accounted for 65.6% of rotaviruses typed, followed by genotypes G2 (20.2%), G9 (7.6%), G4 (4.6%), G6 (1.0%), G3 (0.5%), and G26 (0.5%). VP4 genotype P[8] accounted for 75.0% of strains, genotype P[4] accounted for 23.0% of strains, and the uncommon genotypes P[6], P[9], P[14], and P[19] accounted for 2.0% of strains altogether. These rotavirus genotypes were also found in pediatric patients hospitalized in the same areas and years but in different proportions. Specifically, genotypes G2, G9, and P[4] were more prevalent in sewage samples than among samples from patients, which suggests either a larger circulation of the latter strains through the general population not requiring medical care or their greater survival in wastewaters. A high level of nucleotide identity in the G1, G2, and G6 VP7 sequences was observed between strains from the environment and those from patients.

Molecular analysis of group A rotaviruses detected in adults and adolescents with severe acute gastroenteritis in Italy in 2012.

Hospital-based surveillance of acute gastroenteritis caused by rotavirus has produced ample knowledge on the infection in children, whereas little is known on rotavirus infection among adults. The Italian surveillance program RotaNet-Italia collected 1,595 samples from patients admitted to hospital with gastroenteritis in 2012. All patients presented with vomiting, diarrhea, fever, and/or abdominal pain. Forty-two samples obtained by the RotaNet-Italia (2.6%) were from adolescents or adults (10-89 years). The study compared the genotypes and gene sequences of the rotavirus strains identified in adults with strains obtained from children worldwide. All 42 Italian strains were genotyped by the EuroRotaNet RT-nested-PCR protocols, and 12 rotaviruses from patients >13-year-old were subjected to nucleotide sequencing of their VP7 and/or VP4 genes. All strains analyzed belonged to the common human genotypes G1P[8], G2P[4], G4P[8], and G9P[8], except an uncommon G3P[19] genotype detected in a single patient. Phylogenetic analysis of the 12 strains showed that within each genotype they clustered in RVA lineages reported worldwide. The amino acid sequences of the VP7 and the VP8* hypervariable regions were highly conserved between the RVA strains collected from adults and children, in each lineage. Genotyping, phylogenetic analysis, and the study of viral epitopes revealed that rotaviruses circulating in adults in Italy are closely similar to the strains circulating in children, with high nucleotide identity particularly with strains reported in Europe and Asia. The circulation of the same rotavirus strains in both children and adults suggests that adults may contribute to sustain the circulation of rotaviruses through the population.

Detection of Enteroviruses in Influent and Effluent Flow Samples from Wastewater Treatment Plants in Italy.

This study evaluated the presence and seasonal distribution of polio and other enteroviruses in four wastewater treatment plants in three cities in Italy, using different treatment systems. Detection of enteroviruses was carried out by virus isolation in cell cultures after concentration of water samples collected at both inlet and outlet of the treatment plants, following the methods described in the WHO guidelines. Viral serotypes isolated before and after water treatment were compared. Forty-eight non-polio enteroviruses were isolated from 312 samples collected at the inlet of the four wastewater treatment plants, 35 of which were Coxsackievirus type B (72.9 %) and 13 Echovirus (27.1 %). After treatment, 2 CVB3, 1 CVB5, and 1 Echo 6 were isolated. CVB3 and Echo 6 serotypes were also detected in samples collected at the inlet of the TP, in the same month and year. The high rate of detection of infectious enteroviruses in inlet sewage samples (30.1 %) indicates wide diffusion of these viruses in the populations linked to the collectors. The incomplete removal of infectious viruses following sewage treatment highlights possible risks for public health relate to treated waters discharge into the environment.

Identification and Genotyping of Human Sapoviruses Collected from Sewage Water in Naples and Palermo, Italy, in 2011.

Human sapoviruses were identified in 15 (12.4 %) of 121 inlet sewage samples collected from wastewater treatment plants in Naples and Palermo, Italy, in 2011. All strains, except one GI.1, were genotyped as GI.2 by sequencing a capsid gene fragment. This is the first detection of sapovirus in wastewaters in Italy.
