Application and internal validation of lung ultrasound score in COVID-19 setting: The ECOVITA observational study.

BACKGROUND: The severe acute respiratory syndrome Coronarovirus-2 associated still causes a significant number of deaths and hospitalizations mainly by the development of respiratory failure. We aim to validate lung ultrasound score in order to predict mortality and the severity of the clinical course related to the need of respiratory support. METHODS: In this prospective multicenter hospital-based cohort study, all adult patients with diagnosis of SARS-CoV-2 infection, performed by real-time reverse transcription polymerase chain reaction were included. Upon admission, all patients underwent blood gas analysis and lung ultrasound by expert operators. The acquisition of ultrasound scan was performed on 12 peculiar anatomic landmarks of the chest. Lung ultrasound findings were classified according to a scoring method, ranging 0 to 3: Score 0: normal A-lines. Score 1: multiple separated B-lines. Score 2: coalescent B-lines, alteration of pleural line. Score 3: consolidation area. RESULTS: One thousand and seven patients were included in statistical analysis (male 62.4 %, mean age 66.3). Oxygen support was needed in 811 (80.5 %) patients. The median ultrasound score was 24 and the risk of having more invasive respiratory support increased in relation to higher values score computed. Lung ultrasound score showed negative strong correlation (rho: -0.71) with the P/F ratio and a significant association with in-hospital mortality (OR 1.11, 95 %CI 1.07-1.14; p < 0.001), even after adjustment with the following variables (age, sex, P/F ratio, SpO2, lactate, hypertension, chronic renal failure, diabetes, and obesity). CONCLUSIONS: The novelty of this research corroborates and validates the 12-field lung ultrasound score as tool for predicting mortality and severity clinical course in COVID-19 patients. Baseline lung ultrasound score was associated with in-hospital mortality and requirement of intensive respiratory support and predict the risk of IOT among COVID-19 patients.

Predictors of in-hospital mortality of COVID-19 patients and the role of telemetry in an internal medicine ward during the third phase of the pandemic.

OBJECTIVE: The first pandemic phase of COVID-19 in Italy was characterized by high in-hospital mortality ranging from 23% to 38%. During the third pandemic phase there has been an improvement in the management and treatment of COVID-19, so mortality and predictors may have changed. A prospective study was planned to identify predictors of mortality during the third pandemic phase. PATIENTS AND METHODS: From 15 December 2020 to 15 May 2021, 208 patients were hospitalized (median age: 64 years; males: 58.6%); 83% had a median of 2 (IQR,1-4) comorbidities; pneumonia was present in 89.8%. Patients were monitored remotely for respiratory function and ECG trace for 24 hours/day. Management and treatment were done following the timing and dosage recommended by international guidelines. RESULTS: 79.2% of patients necessitated O2-therapy. ARDS was present in 46.1% of patients and 45.4% received non-invasive ventilation and 11.1% required ICU treatment. 38% developed arrhythmias which were identified early by telemetry and promptly treated. The in-hospital mortality rate was 10%. At multivariate analysis independent predictors of mortality were: older age (R-R for≥70 years: 5.44), number of comorbidities ≥3 (R-R 2.72), eGFR ≤60 ml/min (RR 2.91), high d-Dimer (R-R for≥1,000 ng/ml:7.53), and low PaO2/FiO2 (R-R for <200: 3.21). CONCLUSIONS: Management and treatment adherence to recommendations, use of telemetry, and no overcrowding appear to reduce mortality. Advanced age, number of comorbidities, severe renal failure, high d-Dimer and low P/F remain predictors of poor outcome. The data help to identify current high-risk COVID-19 patients in whom management has yet to be optimized, who require the greatest therapeutic effort, and subjects in whom vaccination is mandatory.

The effect of an antimicrobial stewardship programme in two intensive care units of a teaching hospital: an interrupted time series analysis.

OBJECTIVES: To evaluate the effect of an antimicrobial stewardship programme in two intensive care units (ICUs) of a teaching hospital. METHODS: Between January 2017 and June 2018 we conducted a prospective, interventional, interrupted time-series study, based on Prospective Audit and Feedback in two ICUs of an acute-care teaching hospital. The primary outcomes were the difference in the antibiotic consumption, and the incidence of bloodstream infections (BSI) caused by multidrug-resistant (MDR) organisms. The secondary outcomes included the hospital mortality rate, the mean length of stay and the antibiotic expense. RESULTS: During the study, 231 audits were performed, evaluating 693 antibiotic prescriptions. The programme led to a global reduction in antibiotic consumption, with a change in level (CL) of -324.8 defined daily doses (DDD)/100 patient-days (PD), p 0.04, and particularly in the use of fluoroquinolone: (CL: -63.48 DDD/100 PD, p < 0.001). A non-significant reduction was obtained for the consumption of carbapenems (CL: -34.7 DDD/100 PD, p 0.25) and third- and fourth-generation cephalosporins (CL: -27.3 DDD/100 PD, p 0.102). Furthermore, we registered a significant decrease in all BSI (CL: -5.8 events/100 PD, p 0.026) and in BSI due to MDR Gram-negative organisms (CL: -2.96 events/100 PD, p 0.043). No difference was observed in the hospital mortality and length of stay. CONCLUSIONS: Our study demonstrated that implementation of an antimicrobial stewardship programme in two ICUs of a teaching hospital induced a significant reduction in antibiotic consumption and in the incidence of BSI due to MDR Gram-negative organisms, without any impact on the mortality rate.

Migraine as possible red flag of PFO presence in suspected demyelinating disease.

OBJECTIVES: To investigate a possible association between isolated white matter lesions suggestive of demyelinating disease in magnetic resonance imaging (MRI) and patent foramen ovale (PFO) evidence in migraine patients, with or without aura. MATERIALS: 31 migraine patients, 28 females and 3 males, with MRI evidence of white matter lesions suggestive of demyelinating disease according to the Barkhof Criteria. All patients underwent further diagnostics including lumbar puncture, autoimmunity panel and cardiological evaluation to detect the presence of PFO. The mean duration of follow-up was 3.46 years and MIPAV software was used to analyze MRI imaging. RESULTS: 14 of the 31 patients (45%) had PFO. A significant association was found between PFO and migraine with visual aura (p < 0.001). No difference in lesion number, volume or area between patients with and without PFO was found, but the distribution was mainly occipital (p < 0.001) in patients with PFO. The follow-up showed a stationary lesion load in all PFO patients; no infratentorial or spinal cord lesion and no enhancement or corpus callosum lesion was ever detected. At the end of follow-up four patients developed multiple sclerosis: younger age at first MRI and oligoclonal bands were associated risk factors. CONCLUSIONS: Migraine is often one of the main symptoms leading to MRI, and in many cases white matter lesions of unspecific significance are discovered, thus placing demyelinating diseases in the differential diagnosis. Our study underlines the potential pathogenetic role of PFO in generating white matter lesions in migraine patients (45%), particularly those with visual aura and occipital lesions. For this reason, we affirm that PFO represents a cardinal point in the differential diagnosis of suspected demyelinating disease.

Is it reasonable to abandon obligatory vaccinations in Italy? a 2013 survey.

In Italy, infant vaccinations are mandatory for four infectious diseases: diphtheria, polio, tetanus and hepatitis B. In the past, there was widespread apprehension in Italy that doing away with obligatory vaccinations would reduce the coverage rate, but the possibility of making vaccinations optional has recently become more popular. The objectives of this study were to investigate parental willingness to vaccinate their children if those vaccinations were no longer mandatory and to evaluate the variables influencing this intention. We conducted face-to-face structured interviews with 1,039 parents at public health vaccination centres in four cities of the Campania region of southern Italy. Most respondents (91.9%) said that they would certainly (69.4%) or probably (22.5%) vaccinate their children if vaccinations were not mandatory. The belief that vaccinations are effective and safe was positively associated with willingness to vaccinate their children, whereas having heard that autism is a possible adverse reaction to vaccination was inversely associated with willingness to vaccinate. Nevertheless, in the context of the relatively low 2012* [corrected] vaccination coverage rates in Campania (under the national standard of 95%), our results suggest that eliminating mandatory vaccinations is likely to lead to current coverage rates decreasing to unacceptably low levels, significantly below 90%.

Clinical and virological characteristics associated with severe acute hepatitis B.

To identify early predictors of a severe or fulminant course in patients with acute viral hepatitis B (AVH-B). One hundred and thirty-eight patients with symptomatic acute hepatitis B observed from 1999 to 2012 were enrolled. For each patient, the demographics, risk factors for the acquisition of hepatitis B virus (HBV) infection, clinical, biochemical and virological data (HBV DNA, HBV DNA sequences) were recorded and analysed. The HBV mutants in the polymerase region were sought in 110 (87%) patients by direct sequencing, and the rtM204V/I mutations also by an allele-specific PCR. AVH-B was severe in 13 (9.4%) of the 138 patients enrolled, fulminant in 6 (4.3%) and with a normal clinical course in 119. The 19 patients with severe or fulminant AVH-B more frequently than the 119 with a normal course stated intravenous drug use (63.2% versus 36.1%, p 0.04) and were HBV-DNA negative (31.6% versus 11.8%, p 0.03) and anti-hepatitis C virus (HCV) positive (57.9% versus 19.3%, p 0.0008); the prevalences of different HBV genotypes and of the rtM204V/I mutant were similar in these three forms of AVH-B. A multivariate logistic regression analysis identified a pre-existing HCV chronic infection as the only factor independently associated with a severe or fulminant clinical course of AVH-B (OR 4.89, 95% CI 1.5-15.94, p 0.01). A pre-existing HCV chronic infection was identified as the only factor independently associated with a severe clinical presentation of acute hepatitis B, an association most probably due to the combination of the liver lesions caused by acute hepatitis B and the pre-existing histological abnormalities related to HCV chronic infection.

Role of interleukin 28-B in the spontaneous and treatment-related clearance of HCV infection in patients with chronic HBV/HCV dual infection.

The purpose of this investigation was to evaluate the role of IL28-B polymorphism in the clearance of hepatitis C virus (HCV) in chronic hepatitis B virus (HBV)/HCV coinfection during a long-term follow-up. Thirty-four consecutive patients with HBV surface antigen (HBsAg)-positive/anti-HCV-positive chronic hepatitis were retrospectively enrolled at their first liver biopsy (LB). For all patients, a documented clinical, serological and virological follow-up of at least 3 years (range 3-16 years) after LB and a sample of whole blood for genetic evaluation were available. Of the 24 patients with detectable serum HBV-DNA and HCV-RNA at their first observation, three cleared both HBV-DNA and HCV-RNA, 12 HCV-RNA and five HBV-DNA. Of the seven HBV DNA-positive/HCV RNA-negative patients at enrolment, three cleared HBV-DNA and one remained HBV DNA-positive and became HCV RNA-positive. All three HBV DNA-negative/HCV RNA-positive patients remained unchanged. Compared with the 12 patients with HCV persistence, the 15 patients who cleared HCV were younger, had lower serum alanine aminotransferase (ALT), HCV load, and histological activity index (HAI) and fibrosis score, more frequently had IL28-B CC variant, had been receiving an interferon-based treatment and less frequently cleared serum HBV-DNA. To investigate the relationship between the IL28-B variants and clearance of HCV, excluding the confounding effect of interferon-based treatment, the Mantel-Haenszel test was used, which indicated an association between HCV clearance and IL28-B variants (p = 0.009). In chronic HBV/HCV coinfection, a long-term follow-up showed a frequent spontaneous or treatment-related clearance of active replication of one or both viruses and identified the IL28-B CC genotype as an independent predictor of HCV clearance.

Cord blood unit bankability can be predicted by prenatal sonographic parameters.

OBJECTIVE: To identify possible sonographic prenatal parameters and postnatal parameters in order to obtain more bankable cord blood units (CBUs) containing a high number of primitive progenitor cells, allowing CBUs to be used as a source of haematopoietic progenitors for clinical transplantation. STUDY DESIGN: Prospective study undertaken in the Department of Gynaecology, Obstetrics and Reproductive Science, Second University of Naples, Italy. In total, 219 unrelated CBU donors were enrolled. Ultrasound parameters (biparietal diameter, head circumference, abdominal circumference, femur length, estimation of fetal weight, umbilical artery pulsatility index), collected at hospital admission, together with birth weight and placental weight, were correlated with bankable CBU parameters (CBU volume, total nucleated cell count, CD34+ cell count). RESULTS: Femur length and abdominal circumference correlated positively with bankable CBUs. Receiver operating curve analysis showed that these parameters can identify bankable CBUs. CONCLUSIONS: This is the first prospective study to show the relationship between ultrasonographic fetal parameters at term and the possibility of obtaining high-quality CBUs. As such, cord blood banking could be improved worldwide by performing low-cost ultrasonographic scans.

The role of hypertension, body mass index, and serum leptin levels in patients with endometrial hyperplasia during premenopausal period.

OBJECTIVES: to investigate whether body mass index (BMI), hypertension (HTN), diabetes, age, and physical activity can be considered risk factors for endometrial simple hyperplasia in premenopausal women. Furthermore this study was undertaken to determine whether serum concentration of leptin in patients with BMI>or= 30 kg / m2 with endometrial hyperplasia deviate from values in patients with normal endometrium. MATERIALS AND METHODS: The authors enrolled 167 hyperplasia cases and 282 controls. Demographic characteristics and data on age, diabetes, hypertension, BMI, physical activity, and anthropometric parameters were collected. Leptin concentration in serum was measured with immunoenzymatic test kit from IBL. Univariable and multivariable analysis were performed to verify the association among age, HTN, BMI, physical activity, diabetes, and the presence of uterine hyperplasia. Furthermore the authors evaluated the correlation between BMI and leptin level (with Pearson's linear correlation) in women with simple hyperplasia and in controls. RESULTS: The prevalence of hyperplasia found was 34.4%. The following factors were independently associated with increased risk of endometrial hyperplasia: HTN (odds ratio 3.19, 95% confidence interval 1.20-8.48, p<0.020) and BMI>or=30 Kg/m2 (odds ratio 6.43, 95% confidence interval 3.92-10.53, p<0.000). Mean leptin concentration in serum was higher in patients who had endometrial hyperplasia than in controls (p<0.005) and the leptin levels depended on BMI. CONCLUSIONS: The following are risk factors for endometrial hyperplasia in premenopausal women: BMI>or=30 kg/m2 and HTN (blood pressure>or=130/85 or in therapy). Leptin appears to participate in proliferative processes of the endometrium, depending on BMI. Current guidelines may need to be reconsidered.

Circulating cytokines present in the serum of peripheral arterial disease patients induce endothelial dysfunction.

Peripheral arterial disease (PAD) is a chronic condition caused by atherosclerosis and is a severe complication of type 2 diabetes (T2D). We hypothesised that chronic condition of arterial disease engenders inflammation and endothelial damage in response to circulating cytokines released in the blood stream of PAD patients. We explored the levels of circulating cytokines in PAD patients with and without diabetes by multiplex cytokine array compared with non-PAD controls. Serum from PAD patients with or without diabetes showed high levels of VEGF, IFN-gamma, TNF-alpha, MCP-1, and EGF. VEGF levels correlated with TNF-alpha and IFN-gamma, significantly. Endothelial cells (ECs) were exposed to the different altered cytokines to evaluate changes in cell growth, migration and tubule-like formation, displaying impairment on proliferation, migration and tubule formation. Our findings demonstrate that a set of cytokines is significantly increased in the serum of PAD patients. These cytokines act to induce endothelial dysfunction synergistically. VEGF strongly correlated with TNF-alpha and IFN-gamma, opening new therapeutic perspectives.

Oral candidiasis: a comparison between conventional methods and multiplex polymerase chain reaction for species identification.

BACKGROUND/AIM: Oral candidiasis is the most common fungal infection in dental practice, and is caused by yeasts that are normally present in the endogenous flora. METHODS: To evaluate a rapid diagnostic method for identification of Candida oral isolates, a multiplex polymerase chain reaction (PCR) was carried out on colonies and on oral rinse solutions from 95 subjects with suspected oral candidiasis and results were compared with those from seven commonly used phenotypic identification systems. RESULTS: Between four and nine species were characterized in the samples by the phenotypic methods. PCR identified the same species in 60 (74%) samples from both colony and oral rinse solutions. Statistical analysis, carried out only for the three most frequently isolated species (Candida albicans, Candida glabrata, and Candida tropicalis), showed good concordance in the comparison of multiplex PCR with API 20C AUX and with the Rapid Yeast Identification Panel; conversely, significant differences were registered in the comparison between the molecular method and other phenotypic systems, including four chromogenic media and the automated system Vitek2. DISCUSSION: Multiplex PCR was rapid and effective in the identification of Candida species and allowed the detection of more than one species in the same sample.

Carboplatin and pegylated liposomal doxorubicin for advanced ovarian cancer: preliminary activity results of the MITO-2 phase III trial.

BACKGROUND: Based on the efficacy of pegylated liposomal doxorubicin (PLD) in relapsed ovarian cancer, we are conducting a phase III study comparing carboplatin plus either paclitaxel or PLD as first-line therapy in advanced ovarian cancer. Because of limited phase I and II data on PLD plus carboplatin in this setting, we conducted an interim activity analysis. PATIENTS AND METHODS: Patients with stage 1c-IV epithelial ovarian cancer were randomized to carboplatin AUC 5 plus either paclitaxel 175 mg/m(2) or PLD 30 mg/m(2) every 3 weeks for 6 cycles. The interim activity analysis was planned according to a single-stage phase II design with an auspicated 50% response rate; 50 patients eligible for response assessment were required. Response was defined according to RECIST (Response Evaluation Criteria in Solid Tumors). RESULTS: A complete response was achieved in 14 patients (28%) and a partial response in 20 (40%), which produced an overall response rate of 68%. The activity exceeded the minimum required for study continuation. Stable disease was reported in an additional 10 patients (20%). CONCLUSIONS: The adopted schedule of PLD plus carboplatin demonstrates activity as a first-line treatment for advanced ovarian cancer.

Performance of two commercial blood IFN-gamma release assays for the detection of Mycobacterium tuberculosis infection in patient candidates for anti-TNF-alpha treatment.

The reactivation of latent tuberculosis (TB) is a major complication of tumor necrosis factor (TNF)-alpha inhibitors. Screening for TB infection is recommended before anti-TNF therapy is initiated; however, the use of tuberculin skin testing (TST) is controversial, due to the high rate of false-negative results in patients receiving immunosuppressive treatment. To compare the performance of two commercial interferon (IFN)-gamma release assays (IGRA), T-SPOT.TB (TS-TB) and QuantiFERON-TB Gold "In-tube" (QFT-GIT), with TST for the detection of TB infection in patients due to start anti-TNF therapy, 69 human immunodeficiency virus (HIV)-negative Italian patients (mean age: 45.2 +/- 12.6 years; male=39) were enrolled between September 2005 to August 2006. Patients affected by rheumatoid arthritis (n = 18), psoriatic arthritis (n = 26), ulcerous rectocolitis (n = 6), and Crohn's disease (n = 19) were tested simultaneously with TST, TS-TB, and QFT-GIT. Overall, 26% of patients were positive by TST, 30.4% by TS-TB, and 31.8% by QFT-GIT. Agreement with TST was similar (kappa = 0.21, p = 0.0002 and kappa = 0.26, p < 0.001, respectively). In 11 TST-negative cases, IFN-gamma release assays were positive. In addition, in seven Mantoux-positive cases with no TB risk factors, TST result agreement was achieved with at least one blood test. Indeterminate results were detected in 5.8% and 2.8% of cases, respectively, with TS-TB and with QFT-GIT (p = not significant [ns]). In conclusion, our results suggest that IGRAs may be helpful for screening purposes in patient candidates for anti-TNF therapy to confirm positive TST results and in selected cases when false-negative results are suspected. The utility of blood tests in patients with low or no TB risk remains to be assessed.

Association between threatened pre-term labour and periodontal disease: does a relationship exist? A matched case-control study.

AIM: The relationship between periodontal disease and preterm labour has been target of several studies with contrasting findings. The aim of this study is to verify the association between periodontal diseases in pregnant women and threatened preterm labour (TPL). METHODS: Two hundred and twenty pregnant women were enrolled in a matched prospective case-control study. Matching factors were age, parity and date of admission. Cases were defined as women admitted with a diagnosis of TPL before the 37th week; controls were defined as women with term labour (= or > 37 weeks) in the same ward. Primary exposure was defined as the presence of at least one tooth with probing depth (PD) >6 mm and BOP+. Average pocket depth, full-mouth bleeding on probing (FMBS) and the presence of plaque (FMPS) were also investigated. Matched univariate (McNemar's test and Wilcoxon signed rank test) and multivariate (conditional logistic regression model) analyses were performed. RESULTS: At least one PD >6 mm BOP+ was found in 30 TPL cases (27.3%) and 37 controls (33.6%), without significant difference (P=0.27). There was also no difference was found in shallow pockets. The average pocket depth was similar in TPL cases (2.67 mm) and controls (2.78 mm) (P=0.29). The average FMPS was 56.4% in the cases and 50.7% in the controls, while FMPS was 36.5% and 39.6%, respectively, though these differences are not statistically significant (P=0.26 and P=0.42, respectively). CONCLUSION: From our study, there seems to be no association between threatened pre-term labour and periodontal disease.

Feasibility of primary inguinal hernia repair with a new mesh.

BACKGROUND: The purpose of this study was to evaluate the feasibility of primary inguinal repair with open tension-free and sutureless technique using a new polypropylene "patch and plug system" (Prolene 3D patch), and the quality of the treatment in terms of reduction of postoperative discomfort. METHODS: Fifty-six consecutive patients, mean age 54.5+/-11.2 years, with primary unilateral uncomplicated inguinal hernia, were treated in a day-surgery setting. Collected data included: pain scores at 24 hours, 72 hours, and 7, 15, and 30 days after operation, analgesic medications, return to work and to heavy house and/or moderate sporting activities, and quality of life as measured by Short Form 36 health survey questionnaire (SF-36) before the operation and at 6 months follow-up. RESULTS: Postoperative pain was low: the mean visual analog scale (VAS) scores were 2.8 at 24 h, 1.8 at 72 h, and 0.9, 0.3, and 0.04 at 7, 15, and 30 days, respectively. Analgesic drugs were not used by 66.0% (n=37) of the patients. The mean global time to return to work and to heavy activities was 9.9+/-4.6 and 14.6+/-7.0, days, respectively. Patient satisfaction showed a significant improvement in all SF-36 domain scores at 6 months follow-up (P<0.001). There were no major complications, recurrences, or mortality. CONCLUSIONS: The new mesh seems to satisfy all requirements of a feasible, reliable, and effective device for repairing primary inguinal hernia with high patient comfort.

[Biological risk in the operating room: microbiological monitoring of the environment and analysis of the associated variables]. / Rischio biologico in sala operatoria: monitoraggio micro- biologico ambientale ed analisi delle variabili associate.

The authors present an environmental microbiological monitoring programme carried out over a period of 15 months in 16 operating theatres performing specific types of surgery. The levels of microbial contamination of the air and of four of the most representative surfaces of the clean area were determined at 3 different times for each theatre, both before and during surgery. For the air assessment, the results obtained with three different samplers, Sed-3 Unit, SAS and RCS, were compared. The results were on the whole acceptable, but some poor conditions were detected during the theatres in use, especially in general surgery theatres; in some of these the floors showed levels of contamination consistently exceeding the reference limits. As the monitoring programme proceeded, the microbiological quality of the air and of the surfaces in the theatres notably improved. The three air samplers showed different conditions expressed with units of measure not always readily comparable. For active samplers, the bacterial load determined by RCS, although less variable, were always higher (even 2-3 fold) than those obtained with the SAS. Passive sampling takes longer but determines the real risk of infection for the patients; contemporary determination of the fall-out and the CFU/m3 helps to identify the occupational risks. Since the limit values established by the ISPESL guidelines for the operating theatres have been defined only for active samplers, there is urgent need for more exhaustive national guidelines to define similar values also for passive sampling. The Authors conclude stressing the importance of promoting continuing information-education programmes to heighten the awareness of all those involved in operating theatre activities.

Management of hypertension in chronic kidney disease: the Italian multicentric study.

BACKGROUND: Guidelines have indicated the achievement of blood pressure target (BP <130/80 mmHg) as a priority in the conservative treatment of chronic kidney disease (CKD), but the current implementation of these recommendations in clinical practice is unknown. METHODS: We assessed control rates, treatment and clinical correlates of hypertension in 1201 adult non-dialyzed CKD patients followed up by a nephrologist for at least 6 months. RESULTS: Estimated glomerular filtration rate (GFR) was 32 (SD 15) mL/min/1.73 m2. BP target was not achieved in 88% of patients (95% confidence interval (95% CI): 86-90%). In 84% of patients, BP levels were also above the target at the first visit to the nephrology unit 4.5 yrs previously. The risk of not achieving BP target during the nephro-logy follow-up was associated with older age (odds ratio (OR): 1.24, 95% CI 1.06-1.45, p=0.008), diabetes (OR: 2.25, 95% CI 1.20-4.20, p=0.011), and the duration of hypertension (OR: 1.13, 95% CI 1.02-1.24, p=0.016). Among patients with uncontrolled BP, about 70% received multidrug antihypertensive therapy including renin-angiotensin system (RAS) inhibitors; conversely, diuretic treatment was prescribed in a minority of patients (37%), and at insufficient doses in half the cases, despite the insufficient implementation of a low salt diet (18%). CONCLUSIONS: BP target was not reached in most CKD patients routinely seen in the renal clinics. The main barrier to guideline implementation is possibly the inadequate treatment of extracellular volume expansion despite the large prevalence of factors, such as older age and diabetes, which further enhance the intrinsic BP salt sensitivity of CKD.

Coadministration of losartan and enalapril exerts additive antiproteinuric effect in IgA nephropathy.

Angiotensin-converting enzyme (ACE) inhibitors and AT1-receptor antagonists (ARAs) are widely administered to reduce urinary protein loss and slow the progression of proteinuric nephropathy to end-stage renal failure. Our group recently observed that the combination of ACE inhibitors and ARAs may have an additive antiproteinuric effect, which may occur because ACE inhibitors do not completely reduce angiotensin II (Ang II) production. Ang II is also produced by chymase. Thus, combination therapy better antagonizes the effects of Ang II. The purpose of this study is to ascertain whether the additive antiproteinuric effect of ACE inhibitors plus ARAs is dose dependent and related to the drug-induced reduction in systemic blood pressure. Therefore, enalapril (E; 10 mg/d) and losartan (LOS; 50 mg/d) were randomly administered alone and then in association; initial dosages were doubled when drugs were administered alone and in association. To determine the influence of the drug-dependent effect on reducing blood pressure and the reduction in urinary proteinuria, both ambulatory and office blood pressures were recorded. E and LOS administered alone reduced proteinuria by the same extent; no further reduction was observed when E and LOS alone were administered at a doubled dose. When E and LOS were coadministered, proteinuria decreased by a greater extent compared with E and LOS alone; an additional reduction in proteinuria was observed when combined therapy doses were doubled. The reduction in proteinuria was not correlated with clinical through blood pressure; however, reductions in diastolic and mean ambulatory blood pressures significantly correlated with the decrease in proteinuria, as well as with creatinine clearance. In conclusion, this study shows that combination therapy with E and LOS has an additive dose-dependent antiproteinuric effect that is likely induced by the drug-related reduction in systemic blood pressure. In normotensive proteinuric patients, it is likely that even a small reduction in systemic blood pressure may affect intraglomerular hemodynamics by a great extent because efferent arteriole regulation is hampered more completely by the coadministration of ACE inhibitors and ARAs.

Randomized, controlled trial to compare the J-pouch and W-pouch configurations for ulcerative colitis in the maturation period.

PURPOSE: Proctocolectomy with ileal pouch-anal anastomosis has become the procedure of choice for the treatment of ulcerative colitis. Functional results may differ with different pouch designs. This randomized study aimed to evaluate the relative effectiveness of two-limb J and four-limb W reservoir designs in the so-called maturation period after ileostomy closure. METHODS: Twenty-four patients underwent ileal pouch-anal anastomosis for ulcerative colitis. Eleven were randomly assigned to the J-pouch group and 13 to the W-pouch group. Frequency of defecation and other functional data were collected at 4, 8, and 12 months after ileostomy closure. Maximum tolerated volume was assessed in the same period by a latex balloon inflated with water. Maximum resting anal pressure, maximum voluntary contraction, and the rectoanal inhibitory reflex were assessed in the preoperative period and at 4, 8, and 12 months after ileostomy closure. RESULTS: Frequency of defecation decreased from 4 to 12 months after ileostomy closure in both groups (P = 0.04), but patients with a W-pouch had significantly lower values than patients with J-pouches (P < 0.01). Night-time defecation (P = 0.04) and use of antidiarrheals (P = 0.04) were significantly lower for patients with a W-pouch. Maximum tolerated volume was greater in the W-pouch group throughout the whole period (P = 0.01). Maximum resting anal pressure, maximum voluntary contraction, and rectoanal inhibitory reflex did not differ between the study arms. CONCLUSION: Patients with W-pouch have better functional results than those with J-pouches in the "maturation period" after ileostomy closure.

Prevalence of varicose veins in an Italian elderly population.

The prevalence of varicose veins (VV) in the elderly population of the Campania Region, in Southern Italy, was estimated. A random sample of the people aged more than 65 years was drawn by means of a stratified multistage sampling design warranting that observed percentages were direct estimates of population percentages. The investigation covered 1319 subjects, 560 (42.5%) men and 759 (57.5%) women, their ages ranging from 66 to 96 years with an average value of 74.2 years, who were interviewed and visited by trained physicians. VV were defined as any reticular or truncal visible varicosities of the lower limbs, and investigated symptoms were heaviness, pain, nightly cramps, edema, eczema, hyperpigmentation, and ulceration. Some variables were studied as risk factors: age, sex, lifetime occupation, smoking, alcohol, hypertension, diabetes, and obesity; previous treatment and use of elastic stockings were also studied. Statistical associations were evaluated by Chi-square test, a two-tailed P value of 0.05 being assumed as significance level. In total, 391 (29.6%) subjects were reported to be affected by VV, but the clinical examination was positive in only 362 (27.4%) with a good correspondence between answers and clinical findings.
