Quality of care and clinical inertia in the management of cardiovascular risk factors in patients with type 1 and type 2 diabetes: data from AMD annals

BACKGROUND

Cardiovascular disease is the leading cause of morbidity and mortality among patients with diabetes, and for this reason, all guidelines for CV risk management provide the same targets in controlling traditional CV risk factors in patients with type 1 or type 2 diabetes at equal CV risk class. Aim of our study was to evaluate and compare CV risk management in patients with type 1 and type 2 diabetes included in AMD Annals Database paying particular attention to indicators of clinical inertia.

METHODS

This was a multicenter, observational, retrospective study of AMD Annals Database during year 2022. Patients with diabetes were stratified on the basis of their cardiovascular risk, according to ESC-EASD guidelines. The proportion of patients not treated with lipid-lowering despite LDL cholesterol > to 100 mg/dl or the proportion of patients not treated with antihypertensive drug despite BP > 140/90 mmhg and proportion of patients with proteinuria not treated with angiotensin converting enzyme inhibitors or angiotensinogen receptor blockers (ACE/ARBs) were considered indicators of clinical inertia. The proportion of patients reaching at the same time HbA1c < 7% LDL < 70 mg/dl and BP < 130/80 mmhg were considered to have good multifactorial control. Overall quality of health care was evaluated by the Q-score.

RESULTS

Using the inclusion criteria and stratifying patients by ESC/EASD Cardiovascular Risk categories, we included in the analysis 118.442 patients at High Cardiovascular risk and 416.246 patients at Very High Cardiovascular risk. The proportion of patients with good multifactorial risk factor control was extremely low in both T1D and T2D patients in each risk class. At equal risk class, the patients with T1D had lower proportion of subjects reaching HbA1c, LDL, or Blood Pressure targets. Indicators of clinical inertia were significantly higher compared with patients with T2D at equal risk class. Data regarding patients with albuminuria not treated with RAAS inhibitors were available only for those at Very High risk and showed that the proportion of patients not treated was again significantly higher in patients with T1DM.

CONCLUSIONS

In conclusion, this study provides evidence of wide undertreatment of traditional cardiovascular risk factors among patients with diabetes included in AMD Annals Database. Undertreatment seems to be more pronounced in individuals with T1D compared to those with T2D and is frequently due to clinical inertia.

The AMD ANNALS: A continuous initiative for the improvement of type 2 diabetes care

AIMS

Since 2006, the Italian AMD (Associations of Medical Diabetologists) Annals Initiative promoted a continuous monitoring of the quality of diabetes care, that was effective in improving process, treatment and outcome indicators through a periodic assessment of standardized measures. Here, we show the 2022 AMD Annals data on type 2 diabetes (T2D).

METHODS

A network involving ∼1/3 of diabetes centers in Italy periodically extracts anonymous data from electronic clinical records, by a standardized software. Process, treatment and outcome indicators, and a validated score of overall care, the Q-score, were evaluated.

RESULTS

295 centers provided the annual sample of 502,747 T2D patients. Overall, HbA1c value ≤7.0% was documented in 54.6% of patients, blood pressure <130/80 mmHg in 23.0%, and LDL-cholesterol levels <70 mg/dl in 34.3%, but only 5.2% were at- target for all the risk factors. As for innovative drugs, 29.0% of patients were on SGLT2-i, and 27.5% on GLP1-RAs. In particular, 59.7% were treated with either GLP1-RAs or SGLT2-i among those with established cardiovascular disease (CVD), 26.6% and 49.3% with SGLT2-i among those with impaired renal function and heart failure, respectively. Notably, only 3.2% of T2D patients showed a Q score <15, which correlates with a 80% higher risk of incident CVD events compared to scores >25.

CONCLUSIONS

The 2022 AMD Annals data show an improvement in the use of innovative drugs and in the overall quality of T2D care in everyday clinical practice. However, additional efforts are needed to reach the recommended targets for HbA1c and major CVD risk factors.

Two years follow-up of relapsing eosinophilic pneumonia with concomitant severe asthma successfully treated with benralizumab: A case report and brief review of the literature

Relapsing eosinophilic pneumonia and severe eosinophilic asthma are rare and disabling diseases, which share common inflammatory backgrounds and often require long-term systemic steroid therapy. Benralizumab is a humanized antibody targeting IL-5 receptor that reduces corticosteroid dependence and flares up in severe eosinophilic asthma on long term. In this case report, successful treatment of eosinophilic pneumonia and severe eosinophilic asthma with benralizumab is described after a 2-year follow up, showing the promising results of this therapy for eosinophilic pneumonia management.

Phase II study of eribulin in combination with gemcitabine for the treatment of patients with locally advanced or metastatic triple negative breast cancer (ERIGE trial). Clinical and pharmacogenetic results on behalf of the Gruppo Oncologico Italiano di Ricerca Clinica (GOIRC)

Background

The combination of a microtubule inhibitor (eribulin) with a nucleoside analog (gemcitabine) may synergistically induce tumor cell death, particularly in triple negative breast cancer (TNBC) characterized by high cell proliferation, aggressive behavior, and chemo-resistance.

Patients and methods

This is an open-label, multicenter phase II study evaluating the combination of eribulin (0.88 mg/m²) plus gemcitabine (1000 mg/m²) on days 1 and 8 of a 21-day cycle as either first- or second-line treatment of locally advanced or metastatic TNBC. The primary endpoint was the objective response for evaluable patients. A prospective, molecular correlative study was carried out to assess the role of germinal BRCA pathogenic variants and single nucleotide polymorphisms (SNPs) in predicting efficacy and toxicity of the combination regimen.

Results

From July 2013 to September 2016, 83 evaluable patients were enrolled. They received a median number of six cycles of treatment. An overall response rate (ORR) of 37.3% (31 patients) was observed, with a complete response rate of 2.4% and a partial response rate of 34.9%; the clinical benefit rate was 48.8%. With a median follow-up of 28.8 months, the median response duration was 6.6 months, the median progression-free survival (PFS) was 5.1 months, and the median overall survival (OS) was 14.5 months. The most common grade 3-4 adverse events were aminotransferase elevation (in 25% of the patients) and neutropenia (in 23.8%). Women with BRCA1/2 pathogenic variants were associated with worse ORR, PFS, and OS than BRCA1/2 wild-type carriers. CYP3A4 and FGD4 SNPs were associated with increased risk of liver toxicity. Three different SNPs in CDA∗2, RRM1, and CYP2C8 genes were significantly associated with poorer OS.

Conclusions

The combination of eribulin and gemcitabine showed promising activity and a moderate toxicity profile in metastatic TNBC. BRCA status and pharmacogenetics tests may help identify patients with high probability of response with negligible toxicity.

Abstract P4-02-10: Are fine-needle aspiration (FNA)-derived cell blocks a useful tissue sample surrogate for testing conventional biomarkers and PD-L1 in breast cancer?

Background The diagnosis of breast cancer (BC) is based on clinical examination in combination with imaging and confirmed by pathological assessment of core needle biopsy (CNB) or fine needle aspiration (FNA). The biological profile of the lesion is needed to define prognosis and guide therapy. Given the importance of an early and minimally invasive diagnosis, we aimed to verify whether the biological features detected in FNA-derived cytological material reflect the biological characteristics of surgical specimens.

Methods We used immunohistochemistry and fluorescence in situ hybridization (FISH) to study a panel of biomarkers (ER, PgR, Ki67 and HER2 in 93 patients, programmed death-ligand 1 (PD-L1) in 20 patients) in FNA-derived cell blocks of BC, comparing the results with those obtained on the histological specimens.Immunostaining was performed with the Ventana Benchmark XT system and the Ultraview DAB Detection Kit (Ventana Medical Systems). Confirm anti-ER (clone SP1, Ventana), Confirm Anti-PgR (clone 1E2, Ventana) and Ki67 (clone Mib-1, Dako, Carpinteria, CA, US) antibodies were used. Ventana PD-L1 (SP263) assay (Ventana Medical Systems) was used for PD-L1 immunostaining. HER2 status was analyzed by FISH using PathVysion kit (Abbott Molecular, Abbott Park, Illinois, IL, USA).

Results Median immunopositive values of ER, PgR Ki67, and PD-L1 were similar in cell blocks and surgical samples. Concordance for ER and PgR between FNA and histological samples was 98% and 84%, respectively. With regard to Ki67 and HER2 status, concordance between the two specimen types was 90% and 96%, respectively. PD-L1 expression analyzed in FNA-derived samples was 100% concordant with that of surgical specimens. Tumor subtype classification for triple-negative and HER2-positive tumors in FNA samples was always concordant with the subtype determined in surgical material.

Conclusions We showed that biological marker determination in FNA-derived cell blocks is feasible and provides useful information and comparable results with those obtained by histological evaluation. Given the low cost of the procedure and its minimal impact on patients, that cytological samples could be used as an alternative to tissue samples for early BC biomarker evaluation to facilitate the planning of tailored neoadjuvant therapy.

Abstract P2-04-01: Human papillomavirus (HPV) DNA detection in breast cancer by liquid biopsy: Something new on the horizon?

Background The presence of human papillomavirus (HPV) DNA in breast cancer (BC) tissues has been widely investigated in recent years. HPV DNA has been detected in ductal lavage fluids and in serum-derived extracellular vesicles of patients with benign or in situ breast lesions. However, there are no data attesting to its presence in liquid biopsies of different BC subtypes or to its impact on prognosis.

Methods We analyzed a total of 72 serum samples for the presence of circulating HPV DNA, of which 20 were from luminal A BC (5 relapsed, 15 non relapsed), 17 from luminal B BC (5 relapsed, 12 non relapsed), 15 from triple-negative BC (6 relapsed and 9 non relapsed), 12 from HER2-positive BC (3 relapsed, 9 non relapsed) and 8 from healthy subjects. Circulating DNA was extracted and purified from 500 μl of serum by Qiamp DNA minikit (Qiagen, Milan, Italy) according to the manufacturer's instructions. HPV DNA was assessed by a high-throughput MALDI-TOF mass spectrometry-based method (Mass Array Platform, Agena Bioscience, Hamburg, Germany). The DNA target sequence was amplified by a multiplex PCR with HPV E6 or E7 gene-specific primers. A primer for primer extension annealing to the amplified product was extended at its 3′ terminal base for each HPV type.

Results HPV DNA was detected in 5 BC patients but in none of the healthy controls. None of the serum samples analyzed showed HPV DNA types 16 or 18. Four of the 5 BC cases had high-risk HPV DNA (type 39,45,52,59) and one had low-risk HPV DNA (type 73). The 4 patients with high risk HPV DNA had low-grade cervical intraepithelial neoplasia (CIN 1) detected by Pap smear prior to the diagnosis of BC. No relation was found between HPV infection and tumor subtype or prognosis. Our in vitro studies also revealed the active release of HPV DNA into the extracellular vesicle compartment of cervical cancer cells.

Conclusions Our findings support the feasibility of HPV DNA evaluation by liquid biopsy in BC. They also suggest that circulating HPV DNA in BC patients might be of cervical tissue origin and that the presence of HPV DNA in BC may be a consequence of its spreading from virus-infected tissue such as that of the uterine cervix.

Abstract P1-14-05: Phase II study of eribulin in combination with gemcitabine for the treatment of patients with locally advanced or metastatic triple negative breast cancer (ERIGE Trial). Clinical and pharmacogenetic results on behalf of the Gruppo Oncologico Italiano di Ricerca Clinica (GOIRC)

Background: There are no well-established chemotherapy regimens for metastatic triple negative breast cancer. The combination of a microtubule inhibitor (eribulin) with a nucleoside analog (gemcitabine) may synergistically induce tumor cell death, especially in tumors like triple negative breast cancers (TNBC) characterized by high cell proliferation, aggressive tumor behavior, and chemo-resistance.

Materials and Methods:This is an open-label, national multicenter phase II study evaluating the combination of eribulin (0.88 mg/m2) plus gemcitabine (1000 mg/m2) on day 1 and 8, q21 as either first- or second-line treatment of locally advanced or metastatic TNBC.The primary endpoint was the objective response rate (ORR) for evaluable patients (pts). The study was designed according to the Simon's two stage optimal design. We chose the lower activity (p0) of 0.20 and target activity level (p1) of 0.35. A prospective, molecular correlative study has been being carried out on germinal DNA of study population to assess the role of BRCA mutations and single nucleotide polymorphisms (SNPs) in predicting efficacy and toxicity of the combination regimen.

Results: From July 2013 to September 2016, 83 evaluable pts (37 in the first stage, 46 in the second one) were enrolled. They received a median number of 6 cycles of treatment (range 1-24). The ORR (CR+PR) was 37.35% (90% CI: 28.47-46.93) and the clinical benefit rate (CR+PR+SD ≥ 24wks) was 48.78% (90% CI: 39.24%-58.39%). The most common grade 3-4 adverse events (&gt; 10% of patients) were neutropenia and liver toxicity. With a median follow-up of 28.8 months, the median progression-free survival (PFS) and overall survival (OS) were 5.1 months (95% CI: 4.2-7.0) and 14.7 months (95% CI: 10.2-20.0), respectively. BRCA1/2 deleterious mutations were observed in 15 (22%) out of 68 genotyped pts. Women with BRCA1/2 mutations were associated with worse ORR, PFS and OS than those with BRCA1/2 wild-type. A panel of SNPs in genes of study drug metabolism pathways was evaluated. Among these, CYP3A4 392A &gt;G and FGD4 2044236G&gt;A SNPs were associated with greater liver toxicity by logistic regression analysis. Furthermore, CDA*2 79A&gt;C, RRM1 2455 A&gt;G, and CYP2C8 416G&gt;A SNPs were associated with poorer overall survival by Cox proportional hazards model.

Conclusions:The combination of eribulin and gemcitabine shows promising activity and a moderate toxicity profile in metastatic TNBC. BRCA status and pharmacogenetics tests may help identify pts with high probability of response with negligible toxicity.

Prenatal profile of Pallister-Killian syndrome: Retrospective analysis of 114 pregnancies, literature review and approach to prenatal diagnosis

Pallister-Killian syndrome (PKS) is a tissue limited mosaic disorder, characterized by variable degrees of neurodevelopmental delay and intellectual disability, typical craniofacial findings, skin pigmentation anomalies and multiple congenital malformations. The wide phenotypic spectrum of PKS in conjunction with the mosaic distribution of the i(12p) makes PKS an underdiagnosed disorder. Recognition of prenatal findings that should raise a suspicion of PKS is complicated by the fragmentation of data currently available in the literature and challenges in diagnosing a mosaic diagnosis on prenatal testing. Ultrasound anomalies, especially congenital diaphragmatic hernia, congenital heart defects, and rhizomelic limb shortening, have been related to PKS, but they are singularly not specific and are not present in all affected fetuses. We have combined prenatal data from 86 previously published reports and from our cohort of 114 PKS probands (retrospectively reviewed). Summarizing this data we have defined a prenatal growth profile and identified markers of perinatal outcome which collectively provide guidelines for early recognition of the distinctive prenatal profile and consideration of a diagnosis of PKS as well as for management and genetic counseling.

Metabolic control and complications in Italian people with diabetes treated with continuous subcutaneous insulin infusion

BACKGROUND AND AIM

The objective of this cross-sectional study was to evaluate the degree of glycaemic control and the frequency of diabetic complications in Italian people with diabetes who were treated with continuous subcutaneous insulin infusion (CSII).

METHODS AND RESULTS

Questionnaires investigating the organisation of diabetes care centres, individuals' clinical and metabolic features and pump technology and its management were sent to adult and paediatric diabetes centres that use CSII for treatment in Italy. Information on standard clinical variables, demographic data and acute and chronic diabetic complications was derived from local clinical management systems. The sample consisted of 6623 people with diabetes, which was obtained from 93 centres. Of them, 98.8% had type 1 diabetes mellitus, 57.2% were female, 64% used a conventional insulin pump and 36% used a sensor-augmented insulin pump. The median glycated haemoglobin (HbA_1c) level was 60 mmol/mol (7.6%). The HbA_1c target (i.e. <58 mmol/mol for age <18 years and <53 mmol/mol for age >18 years) was achieved in 43.4% of paediatric and 23% of adult participants. Factors such as advanced pump functions, higher rate of sensor use, pregnancy in the year before the study and longer duration of diabetes were associated with lower HbA_1c levels. The most common chronic complications occurring in diabetes were retinopathy, microalbuminuria and hypertension. In the year before the study, 5% of participants reported ≥1 episode of severe hypoglycaemic (SH) episodes (SH) and 2.6% reported ≥1 episode of ketoacidosis.

CONCLUSIONS

Advanced personal skills and use of sensor-based pump are associated with better metabolic control outcomes in Italian people with diabetes who were treated with CSII. The reduction in SH episodes confirms the positive effect of CSII on hypoglycaemia.

Abstract OT1-03-03: Phase II, open label, randomized, biomarker study of immune-mediated mechanism of action of neoadjuvant subcutaneous trastuzumab in patients with operable or locally advanced/Inflammatory HER2-positive breast cancer. ImmunHER trial on behalf of the Gruppo Oncologico Italiano di Ricerca Clinica (GOIRC)

Background: Tumor-infiltrating lymphocytes (TILs) have been reported to be associated with increased therapeutic efficacy of trastuzumab in the (neo)adjuvant setting for HER2-positive breast cancer (BC). Subcutaneous (SC) trastuzumab has been observed to act at different immunologic levels than IV trastuzumab. Therefore, by modifying the modality of administration of trastuzumab, it could be possible to interfere with different pathways of the immune system and exert a favorable immunomodulation in HER2-positive BC.

Trial design: In this non-comparative, phase II, neoadjuvant, randomized study, patients will be treated with FEC chemotherapy (fluorouracil 500 mg/m2; epirubicin 75 mg/m2; cyclophosphamide 500 mg/m2) q21 for 3 cycles. Then, they will be randomly assigned in a 1:1 ratio to receive: docetaxel (75 mg/m2) plus pertuzumab (840 mg loading dose, then 420 mg) plus IV trastuzumab (8 mg/kg loading dose, then 6 mg/kg) q21 for 4 cycles (Group A) or, docetaxel plus pertuzumab plus SC trastuzumab (fixed dose of 600 mg) q21 for 4 cycles (Group B). After surgery, study patients will receive trastuzumab q21 x 14 cycles using the same formulation (SC or IV) of the preoperative phase.

Eligibility criteria: Patients must have previously untreated, T2-4d primary HER2-positive BC with no metastatic disease. Other inclusion criteria are: age 18 or older; ECOG performance status 0-1; availability of tumor tissue from diagnostic biopsy; normal left ventricular ejection fraction; normal organ and marrow function.

Specific aims: The main objective of this trial is to evaluate variations of host immune response parameters to either trastuzumab SC or trastuzumab IV given in combination with pertuzumab and chemotherapy as neoadjuvant treatment of patients with HER2-positive BC. Tumor samples obtained at diagnosis and at definitive surgery will be centrally analyzed for TILs. Blood samples will be also collected during study treatment for tumor-specific lymphocyte cell activity (TLA) analysis. Feasibility, efficacy, safety and health-related quality of life will be also evaluated.

Statistical methods: The primary endpoint is post-surgery pathologic TIL rate on residual disease. The threshold for classifying subjects with high TILs, or not, is defined as equal to 15%, according to the median TIL rate observed in primary HER2-positive tumors. Because this is a phase II study with 2 non-comparative arms, Simon's optimal 2-stage design will be used for each of the 2 study groups. For each arm we assume: p1 = 0.4, expected rate of subjects with high TILs on residual disease, p0 = 0.1, lowest limit of the subject rate (alpha= 0.05; beta= 0.20).

Present accrual and target accrual: A total of 60 patients (first stage: 16 patients) will be enrolled from multiple institutions. From November 29, 2016 to June 11, 2017, 34 patients have been recruited.

Sentinel lymph node surgery after neoadjuvant chemotherapy in patients with T2 to T4, N0 and N1 breast cancer

BACKGROUND

Histological status of axillary lymph nodes is an important prognostic factor in patients receiving surgery for breast cancer (BC). Sentinel lymph node (SLN) biopsy (B) has rapidly replaced axillary lymph node dissection (ALND), and is now the standard of care for axillary staging in patients with clinically node-negative (N0) operable BC. The aim of this study is to compare pretreatment lymphoscintigraphy with a post primary systemic treatment (PST) scan in order to reduce the false-negative rates for SLNB.

METHODS

In this single-institution study we considered 170 consecutive T2-4 N0-1 M0 BC patients treated with anthracycline-based PST. At the time of incisional biopsy, we performed sentinel lymphatic mapping. After PST, all patients repeated lymphoscintigraphy with the same methodology. During definitive surgery we performed further sentinel lymphatic mapping, SLNB and ALND.

RESULTS

The SLN was removed in 158/170 patients giving an identification rate of 92.9% (95% confidence interval (CI) = 88.0-96.3%) and a false-negative rate of 14.0% (95% CI = 6.3-25.8%). SLNB revealed a sensitivity of 86.0% (95% CI = 74.2-93.7%), an accuracy of 94.9% (95% CI = 90.3-97.8%) and a negative predictive value of 92.7% (95% CI = 86.1-96.8%).

CONCLUSION

Identification rate, sensitivity and accuracy are in accordance with other studies on SLNB after PST, even after clinically negative node conversion following PST. This study confirms that diagnostic biopsy and neoadjuvant chemotherapy maintain breast lymphatic drainage unaltered.

Sympathetic activity and early mobilization in patients in intensive and intermediate care with severe brain injuries: a preliminary prospective randomized study

Background

Patients who experience severe brain injuries are at risk of secondary brain damage, because of delayed vasospasm and edema. Traditionally, many of these patients are kept on prolonged bed rest in order to maintain adequate cerebral blood flow, especially in the case of subarachnoid hemorrhage. On the other hand, prolonged bed rest carries important morbidity. There may be a clinical benefit in early mobilization and our hypothesis is that early gradual mobilization is safe in these patients. The aim of this study was to observe and quantify the changes in sympathetic activity, mainly related to stress, and blood pressure in gradual postural changes by the verticalization robot (Erigo®) and after training by a lower body ergometer (MOTOmed-letto®), after prolonged bed rest of minimum 7 days.

Methods

Thirty patients with severe neurological injuries were randomized into 3 groups with different protocols of mobilization: Standard, MOTOmed-letto® or Erigo® protocol. We measured plasma catecholamines, metanephrines and blood pressure before, during and after mobilization.

Results

Blood pressure does not show any significant difference between the 3 groups. The analysis of the catecholamines suggests a significant increase in catecholamine production during Standard mobilization with physiotherapists and with MOTOmed-letto® and no changes with Erigo®.

Conclusions

This preliminary prospective randomized study shows that the mobilization of patients with severe brain injuries by means of Erigo® does not increase the production of catecholamines. It means that Erigo® is a well-tolerated method of mobilization and can be considered a safe system of early mobilization of these patients. Further studies are required to validate our conclusions.

Trial registration

The study was registered in the ISRCTN registry with the trial registration number ISRCTN56402432. Date of registration: 08.03.2016. Retrospectively registered.
