Clinical characteristics, management and outcome of patients with invasive candidiasis hospitalized in Internal Medicine Units: findings from a registry by the Italian Scientific Society FADOI.

PURPOSE: Invasive candidiasis (IC) is a challenging clinical condition, burdened by relevant mortality and morbidity. There is limited knowledge on the occurrence and management of IC in Internal Medicine Units (IMUs). Aim of this study was to provide real-world data on this topic. METHODS: Consecutive objectively diagnosed cases of IC were collected in this prospective registry, which involved 18 IMUs in Italy. Patients were followed-up to 90 days from the diagnosis of candidemia. RESULTS: A total of 111 patients were observed (median age 78, IQR 67-83) for an overall incidence of infection of 1.89 cases/1000 hospital admissions. Candida albicans was the most frequent isolated species (62%), followed by Candida parapsilosis (17%) and Candida glabrata (13%). Echinocandins and fluconazole were used as initial therapy in 56.8 and 43.2% of patients, respectively. Antifungal therapy was started within 24 h in 18.9% of patients, in 40.6% in the period 1-3 days, and in 40.5% of patients more than 3 days after blood cultures. Death rate was 19.8% at 30 days and 40.5% at 90 days. At multivariable analysis concomitant bacteremia (i.e. polymicrobial sepsis), and fluconazole as the initial therapy were associated with an increased risk of death at 90 days. CONCLUSIONS: The incidence of IC is not negligible, and our registry confirmed that these patients have a relevant mortality rate at 90 days. Concomitant bacteremia, featuring polymicrobial sepsis, and starting antifungal treatment with fluconazole instead of echinocandins independently increase the risk of death. Efforts are needed to improve the awareness and management of IC in IMUs.

Diabetes and CoViD-19: Experience from the frontline of Internal Medicine wards in Italy.

Available data suggest that the issue of CoViD-19 is particularly critical in patients with diabetes. In Italy, Internal Medicine (IM) wards have played a pivotal role in contrasting the spread of SARS-Cov2. During this pandemic, FADOI submitted a brief questionnaire to a group of its members acting as Head of IM units. Considering 38 units, 58% of beds dedicated to CoViD patients in CoViD Hospitals were in charge of IM, and globally cared for 6650 patients during a six-week period. Of these patients, 1264 (19%) had diabetes. Mortality rate in CoViD patients with or without diabetes were 20.5% and 14%, respectively (p < 0.001). Our survey seems to confirm that diabetes is a major comorbidity of CoViD-19, but it does not support an increased incidence of CoViD-19 infection in people with diabetes, if compared with the figures of patients with diabetes and hospitalized before the outbreak. On the other side, patients with diabetes appeared at a significantly increased risk of worse outcome. This finding underlines the importance of paying special attention to this patient population and its management.

Hospitalization and mortality for acute exacerbation of chronic obstructive pulmonary disease (COPD): an Italian population-based study.

OBJECTIVE: Patients with acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD) have a significant mortality and morbidity. Previous studies have identified a number of independent prognostic factors. However, information on hospital admission databases is limited and data regarding short-term prognosis of these patients in Italian hospitals are lacking. Thus, we performed an epidemiological study on hospital admission for COPD acute exacerbation in Italy. PATIENTS AND METHODS: Patients were identified using clinical Modification (ICD-9-CM) codes. Information was collected on baseline characteristics, vital status at discharge, duration of hospitalization, and up to five secondary discharge diagnoses. Comorbidity was evaluated using the Charlson comorbidity index (CCI). RESULTS: During the observation period (2013-2014), 170,684 patients with COPD acute exacerbation were hospitalized. Mean length of hospitalization (LOH) was 9.95±8.69 days and mean in-hospital mortality was 5.30%. These data correspond to the 4.1% of all hospitalizations and to the 2.8% of all the days of hospitalization in Italy during the study period. In-hospital mortality and LOH varied among different regions (from 3.13 to 7.59% and from 8.22 to 11.28 days respectively). Old age, male gender, low discharge volume, previous hospitalization for COPD exacerbation and CCI resulted as significantly associated with higher in-hospital mortality. CONCLUSIONS: Hospitalization for COPD exacerbation is extremely frequent even in contemporary Italian population. COPD exacerbation is clinically demanding with a not negligible short-term mortality rate and a mean LOH approaching 10 days. These latter findings were quite variable in different regions but should be further analyzed to set up appropriate health-care policies on COPD patients.

Lack of association between GSTM1, GSTP1, and GSTT1 gene polymorphisms and asthma in adult patients from Rome, central Italy.

BACKGROUND: Asthma is a complex multifactorial disease that is not yet fully understood. Oxidative stress due to an imbalance between the oxidative forces and the antioxidant defense systems has been implicated in asthma pathogenesis. However, much debate still surrounds the key genetic factors involved in the development of this disease. Candidate genes include the glutathione S-transferases (GSTs). In particular, mu, pi, and theta classes of GSTs play an important role in regulating inflammatory responses. However, few and contradictory data are available on the association between asthma development and GST gene polymorphisms (GSTM1, GSTP1, and GST1). OBJECTIVE: To investigate whether GSTM1, GSTT1, and GSTP1 polymorphisms are associated with asthma development. METHODS: We recruited 200 unrelated healthy individuals and 199 asthmatic patients from Rome in Central Italy. Genotyping of GSTMI and GSTT1 genes was performed by a multiplex polymerase chain reaction (PCR) while the GSTP1 polymorphism (rs1695) was determined using PCR-restriction fragment length polymorphism analysis. RESULTS: Our results suggest that the GST polymorphisms analyzed are not associated with asthma, confirming the uncertain role of GST genes in the development of asthma. CONCLUSIONS: Oxidative stress is certainly involved in the development of asthma, and GSTs may therefore influence asthma risk, although, as our results show, their role in pathogenesis remains to be elucidated. Future studies should focus on the interactions of GST genes with the environment and other antioxidant genes to shed light on the role of GSTs in asthma.

Left ventricular midwall mechanics at 24 weeks' gestation in high-risk normotensive pregnant women: relationship to placenta-related complications of pregnancy.

OBJECTIVES: Most studies during pregnancy have assessed maternal left ventricular (LV) function by load-dependent indices, assessing only chamber function. The aim of this study was to assess afterload-adjusted LV myocardial and chamber systolic function at 24 weeks' gestation and 6 months postpartum in high-risk normotensive pregnant women. METHODS: A group of 118 high-risk women with bilateral notching of the uterine arteries underwent an echocardiographic examination to evaluate midwall mechanics (midwall shortening (mFS%) and stress-corrected midwall shortening (SCmFS%)) of the LV at 24 weeks' gestation and 6 months postpartum. Patients were followed until delivery and pregnancies were classified retrospectively as uneventful (uncomplicated outcome) or complicated. A control group of 54 low-risk women with uneventful pregnancies without bilateral notching was also enrolled. RESULTS: The pregnancy was uneventful in 74 (62.7%) women, whereas 44 (37.3%) developed complications. At 24 weeks' gestation, mFS% and SCmFS% were greater in the uncomplicated-outcome compared with the complicated-outcome group (25.9 ± 4.8 vs 18.8 ± 5.0%, P < 0.001 and 107.9 ± 18.4 vs 77.9 ± 20.7%, P < 0.001, respectively). At 6 months postpartum, SCmFS% remained greater in the uncomplicated-outcome compared with the complicated-outcome group (100.4 ± 21.6 vs 87.8 ± 19.1, P < 0.05). In the uncomplicated-outcome group, SCmFS% was higher during pregnancy than it was postpartum, whereas in the complicated-outcome group, it was lower during pregnancy than it was postpartum (P < 0.05). CONCLUSIONS: Maternal cardiac midwall mechanics appear to be enhanced (SCmFS% increased compared with controls) during pregnancy compared with postpartum in high-risk patients with uncomplicated pregnancy, whereas midwall mechanics are depressed both during pregnancy and postpartum in patients with pregnancy complications.

Medical treatment of early-onset mild gestational hypertension reduces total peripheral vascular resistance and influences maternal and fetal complications.

OBJECTIVE: Complications in early-onset mild gestational hypertension (GH) are better predicted by total peripheral vascular resistance (TPVR) > 1350 dyne than by blood pressure. We therefore aimed to assess the possible reduction of severe complications by lowering TPVR with nitric oxide (NO) donors, oral fluids and standard antihypertensive therapy in women with early-onset mild GH. METHODS: A group of 400 patients with early-onset (20-27 weeks' gestation) mild GH (systolic and diastolic blood pressure < 170/110 mmHg) and TPVR > 1350 dyne were enrolled in a prospective non-randomized trial with sequential allocation: 100 patients were treated with nifedipine (Group A); 100 with nifedipine and NO donors (Group B); 100 with nifedipine and oral fluids (Group C); and 100 with nifedipine, NO donors and oral fluids (Group D). TPVR was checked 1 month after initiation of therapy, and the number of patients with severe maternal and fetal complications was recorded in each group. The relationship between reduction in TPVR and the frequency of severe complications was assessed. RESULTS: Severe complications developed in 51% of patients in Group A, 48% in Group B, 53% in Group C and 35% in Group D, the frequency in Group D being significantly lower than that in the other treatment groups (P < 0.05). A reduction in TPVR of < 15% predicted the occurrence of severe complications with sensitivity 95.2% and specificity 88.3%. In Group D a reduction in TPVR of ≥ 15% was more probable (odds ratio (OR) = 2.03; 95% CI, 1.15-3.60; P < 0.015) and severe complications were less probable (OR = 0.52; 95% CI, 0.29-0.91; P < 0.023). CONCLUSION: In women with early-onset mild GH, combined treatment with NO donors, oral fluids and nifedipine optimally reduces TPVR and seems to reduce maternal and fetal complications.

Glutathione S-transferase gene polymorphisms and air pollution as interactive risk factors for asthma in a multicentre Italian field study: A preliminary study.

BACKGROUND: Asthma is one of the most common chronic diseases. Several studies have indicated that oxidative stress impairs pulmonary function. Glutathione S-transferases (GSTs) are believed to be critical in the protection of cells from reactive oxygen species. AIM: In this case-control study we analysed the possible association between polymorphism in several cytosolic GST genes, air pollution and asthma development. METHODS: Genotyping of GSTM1 and GSTT1 genes was carried out by a multiplex PCR; GSTA1, GSTO1, GSTO2, GSTP1 polymorphisms were determined using the PCR-RFLP method. Data on atmospheric pollutants were collected by the regional air-quality monitoring network. RESULTS: Among all the polymorphisms studied, the frequencies of GSTA1, GSTM1, GSTO2 and GSTT1 genotypes found in the group of asthmatic patients seem to differ from the frequencies of those found in the control group. Air pollutants were analysed and the air quality parameters considered proved to be significantly different, and therefore suitable for this study. CONCLUSION: The final result of this research should hopefully lead to a better understanding of gene-environment interactions, so allowing earlier prediction and diagnosis of asthma disease and providing an efficient means of prevention.

Maternal diastolic dysfunction and left ventricular geometry in gestational hypertension.

The objective of this study was to evaluate diastolic parameters and left ventricular geometry in gestational hypertension. Twenty-one consecutive pregnant women with gestational hypertension and 21 normotensive women matched for age and gestational age were enrolled in the third trimester of gestation. Echocardiographic and uterine color Doppler evaluations were performed. Systolic, diastolic, and mean blood pressure, total vascular resistance (TVR), and uterine resistance index were higher in hypertensive women than in control subjects (P<0.01). Left atrial function and cardiac output were significantly lower in gestational hypertension (P<0.01). Patients with gestational hypertension had longer left ventricular isovolumetric relaxation time (IVRT) (P<0.0001); lower velocity-time integral of the A wave (P<0.05) and of the diastolic pulmonary vein flow (P<0.05); and higher velocity-time integral of the reverse pulmonary vein flow (P<0.05). Systolic fraction of the pulmonary vein flow was higher in women with gestational hypertension than in control subjects (P<0.01); the difference in duration of pulmonary vein flow and A wave was closer to 0 in gestational hypertension (P<0.0001). Altered left ventricular geometry was found in 100% of hypertensive patients and in 19.05% of normotensive patients (P<0.001). IVRT, left ventricular end-systolic volume, atrial function, and uterine resistance index were directly related to TVR (P<0.01); deceleration time of the E wave showed a quadratic correlation with TVR (P<0.01). Gestational hypertension is characterized by an altered cardiac geometric pattern of concentric hypertrophy. The altered geometric pattern assessed during gestational hypertension is associated, in our study, with depressed systolic function, high TVR, altered diastolic function, and left atrial dysfunction. Deceleration time of the E wave, IVRT, and left atrial fractional area change, found in concomitance with the highest TVR, may be useful in the evaluation of cardiac function and hemodynamics present in pregnancy-induced hypertension.
