RESUMO

AIMS: An initiative of continuous monitoring of the quality of diabetes care, promoted by the Association of Medical Diabetologists, is in place in Italy since 2006 (AMD Annals). The initiative was effective in improving quality of care indicators, assessed periodically through standardized measures. Here, we show the 2023 AMD Annals data on type 2 (T2D) and type 1 (T1D) diabetes. METHODS: A network of over 1/3 of diabetes centers in Italy periodically extracts anonymous data from electronic medical records, using a standardized software. Process, treatment and outcome indicators, and a validated score of overall care, the Q-score, were evaluated. RESULTS: 296 centers provided data on 573,164 T2D (mean age 69.7 ± 11.2 years) and 42,611 T1D subjects (mean age 48.6 ± 16.9 years). A HbA1c value ≤ 7.0 % was documented in 56.3 % of patients with T2D and 35.9 % of those with T1D. Only 6.6 % of T2D patients and 3.5 % of those with T1D reached the composite outcome of HbA1c ≤ 7.0 % + LDL-C < 70 mg/dl + BP < 130/80 mmHg. Notably, only 2.8 % and 3.2 % of T2D and T1D patients, respectively, showed a Q score < 15, which correlates with an 80 % higher risk of incident CVD events compared to scores > 25. CONCLUSIONS: We documented an overall good quality of care in both T1D and T2D subjects. However, the failure to achieve the targets of the main risk factors, especially if combined, in a still too large proportion of patients testify the difficulty to apply the more and more stringent indications recommended by guidelines in the everyday clinical practice.

RESUMO

OBJECTIVE: To develop and validate a model for predicting 5-year eGFR-loss in type 2 diabetes mellitus (T2DM) patients with preserved renal function at baseline. RESEARCH DESIGN AND METHODS: A cohort of 504.532 T2DM outpatients participating to the Medical Associations of Diabetologists (AMD) Annals Initiative was splitted into the Learning and Validation cohorts, in which the predictive model was respectively developed and validated. A multivariate Cox proportional hazard regression model including all baseline characteristics was performed to identify predictors of eGFR-loss. A weight derived from regression coefficients was assigned to each variable and the overall sum of weights determined the 0 to 8-risk score. RESULTS: A set of demographic, clinical and laboratory parameters entered the final model. The eGFR-loss score showed a good performance in the Validation cohort. Increasing score values progressively identified a higher risk of GFR loss: a score ≥ 8 was associated with a HR of 13.48 (12.96-14.01) in the Learning and a HR of 13.45 (12.93-13.99) in the Validation cohort. The 5 years-probability of developing the study outcome was 55.9% higher in subjects with a score ≥ 8. CONCLUSIONS: In the large AMD Annals Initiative cohort, we developed and validated an eGFR-loss prediction model to identify T2DM patients at risk of developing clinically meaningful renal complications within a 5-years time frame.

RESUMO

PURPOSE: To evaluate if a web-based telemedicine system (the Glucoonline® system) is effective to improve glucose control in insulin-treated patients with type 1 and type 2 diabetes, as compared to standard of care. METHODS: This was a prospective, randomized, controlled trial, carried out at three tertiary referral centers for diabetes in Italy. Adults with insulin-treated type 1 and type 2 diabetes, inadequate glycemic control, and no severe diabetes-related complications and/or comorbidities were eligible for this study. Patients were randomized to either perform telemedicine-assisted (Group A) or standard (Group B) self-monitoring blood glucose (SMBG) for 6 months. In Group A, patients received prompt feedback about their blood glucose levels and therapy suggestions from the study staff via phone/SMS, when appropriate. In Group B, patients had no remote assistance from the study staff between planned visits. RESULTS: 123 patients were included in the final analysis. After 6 months, patients achieved a significant reduction in HbA1c in Group A (-0.38%, p < 0.05) but not in Group B (+ 0.08%, p = 0.53). A significant difference in the percentage of patients with HbA1c < 7% between Group A and Group B was found after 3 months (28.6% vs 11.1%, p = 0.02). Also, fewer patients (p < 0.05) with HbA1c > 8.5% were found in Group A vs Group B, respectively, after both 3 months (14.3% vs 35.2%) and 6 months (21.8% vs 42.9%). CONCLUSIONS: The use of the Glucoonline™ system resulted in improved metabolic control. Telemedicine services have potential to support diabetes self-management and provide the patients with remote, prompt assistance using affordable technological equipment. Trial registration This study was registered at clinicaltrials.gov (NCT01804803) on March 5, 2013.

RESUMO

OBJECTIVE: The aim of the present study was to systematically assess the value of contrast-enhanced ultrasound (CEUS) vs. conventional transthoracic ultrasound (TUS) in improving diagnostic accuracy of percutaneous needle biopsy (PTNB) for subpleural lung lesions. PATIENTS AND METHODS: 232 patients with subpleural lesions were 1:1 randomly assigned to a group were CEUS was performed (n=116, mean age=65.5±5.6, M=69) or not (n=116, mean age=66.0±5.3, M=70). For CEUS study was used an injection of 4.8 mL of SonoVue (Bracco, Italy). For PTNB was employed a Menghini-modified technique with a semi-automatic 18-gauge needle. RESULTS: The mean diameter of subpleural lesions was 2.85±0.7 cm in the CEUS+ group and 2.95±0.6cm in the CEUS- group. Only 3 lesions, 1 in the CEUS+ group and 2 in the CEUS- group measured >5 cm. CEUS showed no superiority in terms of diagnostic accuracy compared to conventional TUS (p=0.34). Similar results were obtained in the sub-analysis of lesions sized between 1-2 cm (p=1.00) and 2-5 cm (p=0.08). As the lesion size increased, the detection rate of necrosis in lesions increased by CEUS (from 8% to 31%). CEUS showed no superiority in terms of diagnostic accuracy in the sub-analysis of necrotic lesions at CECT (p=0.38). AUC values for both the groups assessed an excellent diagnostic yield for TUS-PTNB (≥0.80). CONCLUSIONS: CEUS study does not improve the diagnostic accuracy of TUS-guided PTNB for peripheral lung lesions <5 cm of diameter. Further studies evaluating CEUS guidance for larger (>5 cm) and necrotic lesions are needed prior that its potential can be clarified.

RESUMO

OBJECTIVE: Sepsis is one of the most common complications and causes of death in patients with Alcohol-related Liver Disease. This narrative review will focus on several aspects of sepsis in the context of Alcohol-related Liver Disease. The pathophysiology of the increased susceptibility to infections consists mainly of impaired innate and adaptive immunity, changes in gut microbiota with consequent gut translocation of bacteria due to both alcohol abuse and the underlying liver disease. The diagnosis of sepsis in the context of Alcohol-related Liver Disease is challenging. Moreover, the use of classical acute-phase serum proteins (e.g., C-reactive protein and procalcitonin) has several limitations in this setting. The early administration of an adequate antibiotic treatment is pivotal. Finally, measures of infection control and prevention are needed because the prognosis of sepsis in patients affected by Alcohol-related Liver Disease is poor.

RESUMO

Mycoplasma pneumoniae infection is frequent but generally mild or self-limiting. Approximately 10% of cases develop clinical signs of pneumonia with "atypical" radiographic pattern. However, mycoplasma pneumoniae can be responsible for a variety of extrapulmonary manifestations, potentially involving all systems and apparatuses. Although exact pathophysiological mechanisms are not completely known, these could be secondary to direct invasion of the target organ, immunological damage due to molecular mimicry or vascular obstruction. A 45-year-old man was admitted to Internal Medicine Unit because of fever, dry cough and fatigue lasting 15 days. Fever disappeared after starting clarithromycin. About 72 h after admission the patient complained of right calf pain and tachypnea. The presence of anti-mycoplasma antibodies suggested mycoplasma pneumoniae infection. Moreover, a diagnosis of venous thrombo-embolism was performed. Given the absence of classical risk factors for thrombosis, patient was investigated for inherited and acquired thrombophilia and tested positive for antiphospholipid antibodies. A review of the English literature on the association between m. pneumoniae and pulmonary embolism will be provided in order to underline the possible pathogenetic role of antiphospholipid antibodies in this setting. Clinicians should outweigh risk and benefits for LMWH prophylaxis case by case considering these adjunctive pro-thrombotic mechanisms in patients m. pneumoniae infection.

RESUMO

OBJECTIVE: Prior cardiovascular event and kidney dysfunction are both strong risk factors for coronary artery disease. The aim of this study is to assess coronary atherosclerotic burden in a large population of patients undergoing coronary angiography, according to prior cardiovascular event or chronic kidney disease. PATIENTS AND METHODS: We evaluated 700 consecutive patients who underwent coronary angiography (CA). Serum creatinine to estimate glomerular filtration rate (eGFR) was measured. Clinically significant coronary artery disease (CAD) was defined by the presence of a coronary lesion resulting in a luminal stenosis >50%. For the purpose of the study, the whole population was divided into 4 subgroups according to the presence/absence of eGFR <60 ml/min/1.73 m2 or prior cardiovascular event: eGFR≥60/no event (Group A), eGFR≥60/yes event (Group B), eGFR<60/no event (Group C), eGFR<60/yes event (Group D). PATIENTS: As expected, patients in group D had the worst clinical and biochemical profile. These patients also presented the highest values of urinary albumin creatinine ratio (ACR, p<0.001) and the lowest values of eGFR (p<0.01). One-hundred-ninety-six patients had three-vessel disease. Patients who had undergone PCI procedure showed a lower eGFR as compared to patients who had not (p=0.009). Considering group A as reference, the risk of having three-vessel disease was increased in group B (OR= 2.09; 95% CI 1.37-3.19), in group C, (OR= 1.80; 95% CI 1.04-3.14), and finally in group D (OR= 3.35; 95% CI 2.01-5.58). The risk carried by group C was not significantly different from that carried by Group B: OR= 0.86; 95% CI 0.5-1.5. CONCLUSIONS: In our study, low eGFR seems to have the same excess risk of prior CV event.

RESUMO

AIMS: The present study aimed to evaluate the trabecular and cortical bone components using Trabecular Bone Score (TBS) and its association with estimated-Glomerular Filtration Rate (e-GFR) in T2DM patients. METHODS: An assessment both of bone mineral density (BMD) and vertebral bone microarchitecture was performed in all patients using TBS iNsight® software version 3.0.2.0. Furthermore, the total population was divided into two groups based on the value of the eGFR (eGFR < o > at 60 ml/min/1.73 m2). RESULTS: TBS value was lower in patients with low e-GFR than that in patients with higher e-GFR (1.246 ± 0.125 vs 1.337 ± 0.115, respectively, p = 0.013 adjusted by gender and age) while there was no difference in total BMD value between two groups. In the multivariate model taking into account several possible confounders, such as age, gender, duration of diabetes, BMI, LDL cholesterol, serum calcium and HbA1c, the correlation between e-GFR and TBS remained significant (p: 0.046). CONCLUSIONS: In individuals with T2DM and reduced kidney function, TBS provides information independent of BMD, age and gender. TBS may be a useful additional tool to predict fracture risk in this unique population.

RESUMO

OBJECTIVE: Sepsis is a life-threatening disease resulting from the interaction between pathogen and host response; its dysregulation causes organ dysfunction, high morbidity, and mortality. Despite the increase of septic patients admitted to Internal Medicine wards, data about clinical predictors of mortality in this setting are still lacking. The aim of this study was to evaluate the role of MEDS score and vitamin D as predictors of mortality (28-day and 90-day) in septic patients admitted to the Internal Medicine department. PATIENT S AND METHODS: Prospectively collected clinical data, lab tests including vitamin D, and clinical scores (SIRS, MEDS, SCS, REMS, SOFA, qSOFA) were retrospectively analyzed. Eighty-eight microbiologically identified septic patients (median age 75 years old, IQR 65-82 years old; range 37-94 years old) were evaluated. RESULTS: Twenty-three patients (26.1%) died at 28 days, 33 (37.5%) died at 90 days. The logistic regression showed a positive effect of MEDS score (p=0.006; OR 1.24, 95% CI 1.08-1.49), and a negative effect of low vitamin D levels (p=0.008, OR 0.83, 95% CI 0.72-0.94) on mortality. Moreover, the cut-off of 7 points for MEDS score and of 7 ng/ml for vitamin D levels significantly predicted poor prognosis at 28 and 90 days. CONCLUSIONS: MEDS score and vitamin D levels represent independent predictors of mortality in a cohort of Internal Medicine septic patients. Further studies on larger samples are needed to confirm our results and to clarify the pathophysiological mechanisms at the basis of vitamin D deficiency as a predictor of mortality in septic patients.

RESUMO

OBJECTIVE: Paradoxical embolism represents a rare condition occurring when a thrombus originating from venous system produces pulmonary embolism and systemic embolization through an intracardiac or pulmonary shunt. The evidence of a thrombus entrapped in a patent foramen ovale (PFO) is an even more rare condition. There is uncertainty about the optimal treatment strategy. PATIENTS AND METHODS: A 58-year-old male patient was admitted to our Internal Medicine Unit with the diagnosis of bilateral bronchopneumonia. During hospitalization, the co-occurrence of chest pain and amaurosis led us to hypothesize a paradoxical embolism. RESULTS: Transthoracic echocardiography showed the presence of a thrombus stuck over the interatrial septum. A contrast-enhanced chest CT scan showed multiple pulmonary embolisms and brain CT scan documented a hypodense area, of ischemic significance, in the left occipital lobe near tentorium. In order to prevent further embolization, emergency cardiac surgery (right atriotomy, removal of thrombus and closure of the PFO, pulmonary thrombectomy) was performed without complications. CONCLUSIONS: Although rare, the evidence of a thrombus stuck in a patent foramen ovale represents a clinical emergency. The optimal therapeutic approach is still debated. The surgical correction seems to be a safe and effective option for these patients.

RESUMO

BACKGROUND: Diabetes mellitus (DM) is a chronic-degenerative disease associated with a high risk of chronic complications and comorbidities. The aim of this study is to estimate the average annual cost incurred by the Italian National Health Service (NHS) for the treatment of DM stratified by patients' comorbidities. Moreover, the model estimates the economic impact of implementing good clinical practice for the management of patients with DM. METHODS: Data were extrapolated from administrative database of the Marche Region and specific inclusion and exclusion criteria were developed from a clinical board in order to estimate patients with DM only, DM+1, DM+2, DM+3 and DM+4 comorbidities (cardiovascular disease, neuropathy, nephropathy and retinopathy). Regional data were considered a good proxy for implementing a previously developed cost-of-illness (COI) model from Italian NHS perspective already published. A scenario analysis was considered to estimate the economic impact of good clinical practice implementation in the treatment of DM and its comorbidities in Italy. RESULTS: The model estimated an average number of patients with DM per year in the Marche region of 85.909 (5.5% of population) from 2008 to 2011. The mean costs per patients with DM only, DM+1, DM+2, DM+3 and DM+4 comorbidities were €341, €1,335, €2,287, €5,231 and €7,085 respectively. From the Italian NHS perspective, the total economic burden of DM in Italy amounted to €8.1. billion/year (22% for drugs, 74% for hospitalization and 4% for visits). Scenario analysis demonstrates that the implementation of good clinical practice could save over €700 million per year. CONCLUSIONS: This model is the first study that considers real world data and COI model to estimate the economic burden of DM and its comorbidities from the Italian NHS perspective. Integrated management of the patients with DM could be a good driver for the reduction of the costs of this disease in Italy.

RESUMO

BACKGROUND: The guidelines for digital ulcers (DUs) management in systemic sclerosis (SSc) indicate the use of iloprost to induce wound healing and bosentan to prevent the onset of new DU. The aim of our study was to evaluate whether the combination treatment may surmount the effect of the single drug. METHODS: We analyzed data regarding 34 patients with SSc and at least one active DU persisting despite 6 months of iloprost therapy, and treated for other 6 months with a combination therapy, i.e. iloprost plus bosentan. RESULTS: Overall, patients initially presented 69 DUs (58 on the fingers and 11 on the legs). At the end of the study 34 (49.3%) DUs were completely healed (responding, R), 18 (26.1%) started the healing process (partially responding, PR), and 17 (24.6%) did not respond (NR) to therapy. No new DU was recorded and the ulcers localized on the legs did not respond to the combination therapy. Finally, data have been analyzed by dividing the patients in two groups according to the fibrosis level on the finger. In the group with mild fibrosis, 83.4% of DUs resulted with showing complete healing while, in the group with severe fibrosis, only 18% of DUs were healed (P = 0.024). CONCLUSION: The treatment with iloprost plus bosentan is effective in determining healing of DUs in SSc patients with mild digital skin fibrosis. Conversely, the severity of skin fibrosis strongly influences the healing process of DUs. The study confirmed the efficacy of bosentan to prevent onset of new DUs.

RESUMO

BACKGROUND AND AIMS: The rate of mortality in diabetic patients, especially of cardiovascular origin, is about twice as much that of nondiabetic individuals. Thus, the pathogenic factors shaping the risk of mortality in such patients must be unraveled in order to target intensive prevention and treatment strategies. The "Sapienza University Mortality and Morbidity Event Rate (SUMMER) study in diabetes" is aimed at identifying new molecular promoters of mortality and major vascular events in patients with type 2 diabetes mellitus (T2DM). METHODS/DESIGN: The "SUMMER study in diabetes" is an observational, prospective, and collaborative study conducted on at least 5000 consecutive patients with T2DM, recruited from several diabetes clinics of Central-Southern Italy and followed up for a minimum of 5 years. The primary outcome is all-cause mortality; the secondary outcomes are cardiovascular mortality, acute myocardial infarction, stroke, and dialysis. A biobank will be created for genomic, transcriptomic, and metabolomic analysis, in order to unravel new molecular predictors of mortality and vascular morbidity. DISCUSSION: The "SUMMER study in diabetes" is aimed at identifying new molecular promoters of mortality and major vascular events in patients with T2DM. These novel pathogenic factors will most likely be instrumental in unraveling new pathways underlying such dramatic events. In addition, they will also be used as additional markers to increase the performance of the already existing risk-scoring models for predicting the above-mentioned outcomes in T2DM, as well as for setting up new preventive and treatment strategies, possibly tailored to specific pathogenic backgrounds.

RESUMO

Mortality rate of diabetic patients is twice as much that of non-diabetic individuals. The role of obesity on mortality risk in patients with type 2 diabetes is controversial. Aim of our study was to address the relationship between obesity and all-cause mortality in a real-life set of white patients with type 2 diabetes from central-southern Italy from the Gargano Mortality Study (GMS). In addition, we used genetic data from genome-wide association studies (GWAs)-derived single nucleotide polymorphisms (SNPs) firmly associated with body mass index (BMI), in order to investigate the intrinsic nature of reduced mortality rate we, in fact, observed in obese patients. Study subjects with type 2 diabetes (n = 764) are part of the GMS, which is aimed at unraveling predictors of incident all-cause mortality. Time-to-death analyses were performed by Cox regression. Association between genotype risk score and obesity was tested by logistic regression. Of the 32 SNPs firmly associated with BMI, we investigated those with BMI ß value ≥0.10 kg/m(2) and allele frequency ≥10 %. Genotyping was performed by KBioscience (http://www.lgcgenomics.com/). In GMS, obesity predicted a 45 % reduction in all-cause mortality. Individuals with high "obesity genetic load" (i.e., those carrying >9 risk alleles) were 60 % more likely to be obese as compared to individuals with low "obesity genetic load." Most importantly, mortality rate was not different in individuals with high and low "obesity genetic load," thus indicating no role of obesity genes on all-cause mortality and speaking against a cause-effect relationship underlying the association between obesity and reduced mortality rate.

RESUMO

Several lines of evidence suggest a pathogenic role of insulin resistance on kidney dysfunction. Potential mechanisms are mostly due to the effect of single abnormalities related to insulin resistance and clustering into the metabolic syndrome. Hyperinsulinemia, which is inevitably associated to insulin resistance in non diabetic states, also appears to play a role on kidney function by inducing glomerular hyperfiltration and increased vascular permeability. More recently, adipocytokine which are linked to insulin resistance, low grade inflammation, endothelial dysfunction and vascular damage have been proposed as additional molecules able to modulate kidney function. In addition, recent evidences point also to a role of insulin resistance at the level of the podocyte, an important player in early phases of diabetic kidney damage, thus suggesting a new mechanism through which a reduction of insulin action can affect kidney function. In fact, mouse models not expressing the podocyte insulin receptor develop podocytes apoptosis, effacement of its foot processes along with thickening of the glomerular basement membrane, increased glomerulosclerosis and albuminuria. A great number of epidemiological studies have repeatedly reported the association between insulin resistance and kidney dysfunction in both non diabetic and diabetic subjects. Among these, studies addressing the impact of insulin resistance genes on kidney dysfunction have played the important role to help establish a cause-effect relationship between these two traits. Finally, numerous independent intervention studies have shown that a favourable modulation of insulin resistance has a positive effect also on urinary albumin and total protein excretion. In conclusion, several data of different nature consistently support the role of insulin resistance and related abnormalities on kidney dysfunction. Intervention trials designed to investigate whether treating insulin resistance ameliorates also hard renal end-points are both timely and needed.

RESUMO

AIMS/HYPOTHESIS: Insulin resistance is associated with reduced serum adiponectin and increased albuminuria levels. Thus, one would anticipate an inverse relationship between circulating adiponectin and albuminuria. However, several studies have described a 'paradoxical' elevation of serum adiponectin in patients with elevated albuminuria. These findings may have been confounded by the presence of diseases and related treatments known to affect circulating adiponectin and albuminuria. We therefore studied the relationship between circulating adiponectin and albuminuria in the absence of such confounders. METHODS: To this purpose, the relationship between adiponectin isoforms and albumin:creatinine ratio (ACR) was investigated in a family-based sample of 634 non-diabetic untreated white individuals with normal kidney function. We also investigated whether the two variables share a common genetic background and addressed the specific role of the gene encoding adiponectin on that background by genotyping several ADIPOQ single nucleotide polymorphisms (SNPs). RESULTS: ACR was directly associated with high molecular weight (HMW) adiponectin isoform (p = 0.024). The two variables shared some genetic correlation (ρ(g) = 0.38, p = 0.04). ADIPOQ promoter SNP rs17300539 was associated with HMW adiponectin (p = 4.8 × 10(-5)) and ACR (p =0.0027). The genetic correlation between HMW adiponectin and ACR was no longer significant when SNP rs17300539 was added to the model, thus reinforcing the role of this SNP in determining both traits. CONCLUSIONS/INTERPRETATION: Our study shows a positive, independent correlation between HWM adiponectin and ACR. ADIPOQ variability is associated with HMW adiponectin and ACR, and explains some of the common genetic background shared by these traits, thus suggesting that ADIPOQ and HMW adiponectin modulate albuminuria levels.

RESUMO

BACKGROUND AND AIMS: Obesity is a potential risk factor for renal disease in non-diabetic subjects. It remains unclear whether this also applies to diabetic patients. We investigated whether obesity predicted changes in albumin excretion rate in individuals with type 2 diabetes. METHODS AND RESULTS: Fifty Italian diabetes outpatient clinics enrolled a random sample of 1289 patients. A morning spot urine sample was collected to determine urinary albumin/creatinine ratio (ACR) at baseline and after 1 year from the study initiation. Progression of albumin excretion was defined as a doubling in ACR, while regression was defined as a 50% reduction. Multivariate logistic regression analyses were used to evaluate correlates of these outcomes. Data are expressed as odds ratios (OR) with 95% confidence intervals (CI). The risk of progression increased by 7% (OR=1.07; 95%CI 1.00-1.15) for every 5-cm increase in waist circumference measured at baseline, and by 17% (OR=1.17; 95%CI 1.03-1.33) for every one-unit increase in BMI during follow-up. The likelihood of regression was not independently associated with any of the variables investigated. The effect of obesity on progression of ACR was independent of metabolic control, blood pressure, treatment, and baseline level of albumin excretion. CONCLUSIONS: We found a tight link between obesity and changes in albumin excretion in diabetic subjects, suggesting potential benefits of interventions on body weight on end-organ renal damage.
