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.

INTRODUCTION: Radon and its decay products may cause substantial health damage after long-term exposure. The aim of the study was to perform a spatial analysis of radon concentration in the Salento peninsula, province of Lecce (South-eastern Italy) in order to better characterize possible risk for human health, with specific focus on lung cancer. METHODS: Based on previous radon monitoring campaigns carried out in 2006 on behalf of the Local Health Authority (ASL Lecce) involving 419 schools and through the application of kriging estimation method, a radon risk map was obtained for the province of Lecce, in order to determine if areas with higher radon concentrations were overlapping with those characterized by the highest pulmonary cancer incidence and mortality rates. RESULTS: According to our data, areas at higher radon concentrations seem to overlap with those characterized by the highest pulmonary cancer mortality and incidence rates, thus indicating that human exposure to radon could possibly enhance other individual or environmental pro-carcinogenic risk factors (i.e. cigarette smoking, air pollution and other exposures). CONCLUSIONS: The radon risk should be further assessed in the evaluation of the causes resulting in higher mortality and incidence rates for pulmonary cancer in Salento area vs Italian average national data. For these reasons, ASL Lecce in cooperation with ARPA Puglia and CNR-IFC has included the monitoring of individual indoor radon concentrations in the protocol of PROTOS case-control Study, aimed at investigating the role of different personal and environmental risk factors for lung cancer in Salento.

OBJECTIVE: The aim of our scoping review was to summarize the state of the art regarding micronutrients in order to identify which of them might effectively improve health status in the areas typically impaired in older people: bone, skeletal muscle, and cognitive function. DESIGN: Scoping review. METHODS: The Italian Study Group on Healthy Aging by Nutraceuticals and Dietary Supplements (HANDS) performed this scoping review, based on the following steps: doing a list of micronutrients related with musculoskeletal or cognitive functions, included in dietary supplements and nutraceuticals commercialized in Italy; planning a research on PubMed, according to an evidence-based approach, in order to the most relevant positive study for each micronutrient into each of the three areas involved (bone, skeletal muscle and cognitive function); identifying the micronutrients effective in maintaining or achieving an adequate health status in older people, specifying the effective and safe daily doses, according to the selected studies. RESULTS: In literature we found 12 relevant positive studies (1 international society guidelines/recommendations, 1 systematic review, 7 randomized controlled trials, and 3 prospective cohort studies). We showed that only 16 micronutrients resulted to have appropriate scientific evidences in terms of improving musculoskeletal health and/or cognitive function in older people: beta-alanine, calcium, creatine, fluorides, leucine, magnesium, omega-3 fatty acids, potassium, vitamin B6, vitamin B9, vitamin B12, vitamin C, vitamin D, vitamin E, vitamin K2, and zinc. CONCLUSION: This scoping review showed that selected micronutrients in adequate doses might have an ancillary role in musculoskeletal health and cognitive functions in older people.

The article describes the adaptation of a model to estimate the burden of postmenopausal osteoporosis in women aged 50 years and over in Italy between 2010 and 2020. For this purpose, a validated postmenopausal osteoporosis disease model developed for Sweden was adapted to Italy. For each year of the study, the 'incident cohort' (women experiencing a first osteoporotic fracture) was identified and run through a Markov model using 1-year cycles until 2020. Health states were based on the number of fractures and deaths. Fracture by site (hip, clinical vertebral, non-hip non-vertebral) was tracked for each health state. Transition probabilities reflected fracture site-specific risk of death and subsequent fractures. Model inputs specific to Italy included population size and life tables from 1970 to 2020, incidence of hip fracture and BMD by age in the general population (mean and standard deviation). The model estimated that the number of postmenopausal osteoporotic women would increase from 3.3 million to 3.7 million between 2010 and 2020 (+14.3%). Assuming unchanged incidence rates by age group over time, the model predicted the overall number of osteoporotic fractures to increase from 285.0 to 335.8 thousand fractures between 2010 and 2020 (+17.8%). The estimated expected increases in hip, vertebral and non-hip non-vertebral fractures were 22.3, 17.2 and 16.3%, respectively. Due to demographic changes, the burden of fractures is expected to increase markedly by 2020.

Type 2 diabetes mellitus (T2DM) is associated with a higher risk of fractures even in presence of normal or increased bone mineral density. The purpose of this three-year longitudinal study was to evaluate the risk of osteoporotic fractures by assessing the changes of Quantitative Ultrasound (QUS) parameters in a group of postmenopausal women with type 2 diabetes mellitus (T2DM) compared with non-diabetic controls. The measurements were taken on a group of 18 postmenopausal women affected by T2DM and 18 healthy age-matched controls, aged 55-70 years, referring to the Osteolab laboratory at the ISBEM Research Institute (Brindisi, Italy) between 2009 and 2013. Subjects had baseline and 3-year follow-up measurements with phalangeal QUS carried out by a DBM Sonic Bone Profiler 1200 (Igea®); medical history, current drug therapies and risk factors for fractures were recorded for each patient. The analyzed phalangeal QUS parameters were Amplitude-Dependent Speed of Sound (AD-SoS), Bone Transmission Time (BTT), Fast Wave Amplitude (FWA) and Signal Dynamic (SDy). At the baseline visit we found no statistically significant difference between T2DM and non-diabetic patients when looking at phalangeal QUS parameters. At the three-year follow-up visit, a significantly higher decrease of both BTT (P<0.001) and AD-SoS (P<0.001) parameters was found in the T2DM group. On the contrary, the decrease of FWA was significantly higher in non-diabetic controls (P<0.001). Our data confirm the ability of phalangeal QUS to detect differences in the risk of osteoporotic fractures in T2DM postmenopausal women compared to non-diabetic controls. The study suggests that T2DM women present a higher cortical porosity and increased trabecular bone density compared to non-diabetic controls, respectively shown by the higher decrease of both AD-SoS and BTT and the lower decrease of FWA.

OBJECTIVE: Alendronate is a second generation bisphosphonate which has been widely used in medical practice for two decades to treat osteoporosis and prevent fragility fractures both in elderly people and in younger patients. METHODS: Since many papers have been recently published and new formulations or dosages have been developed, our aim was to review the most significant medical literature addressing the issues of efficacy, safety, posology and formulations of the treatment with alendronate in osteoporotic patients. RESULTS: The efficacy of alendronate in reducing the risk of vertebral and non-vertebral fractures has been demonstrated in several studies. Despite favourable data coming from clinical trials, tolerability of alendronate represented a critical issue since its introduction into real clinical practice, possibly leading to early discontinuation of the therapy, especially when combined with lack of motivation of the patient. For this reason, new dosages and formulations of alendronate have been developed, alone or in combination with vitamin D, which have shown to reduce the impact of gastro-oesophageal adverse events, and minimize discomfort due to the need of adopting unfavourable postural positions every day, fasting for at least one hour. CONCLUSIONS: Alendronate is the most frequently used antifracture therapy among those currently available. The increasing use of the 70 mg weekly dosages and newest formulations of this drug are expected to reduce adverse events and increase adherence to the antifracture therapy, thus resulting in better clinical outcomes when treating osteoporotic patients.

OBJECTIVE: We developed a standardized technique for ultrasound guided intra-articular injection of the hip joint with the purpose of extending routine intra-articular injection of hyaluronans and steroids to the hip, as commonly used in the knee. In this article we report the safety of this technique in an extended series of patients. PATIENTS AND METHODS: Patients were injected supine with an anterosuperior approach under ultrasound guidance. The Us probe is applied with a target device for biopsy. RESULTS: The standardised technique was used to inject 1906 patients with 4002 injections of hyaluronan products over a four-year period. The treatment was well tolerated with few, and exclusively local, side effects. CONCLUSIONS: The administration of hyaluronans under ultrasound-guided intra-articular injection is a safe technique for treatment of rheumatic diseases of the hip.

Bone mass increases steadily until age 20-30 years, when peak bone mass (PBM) is acquired. Nutrition plays a critical role in achievement of the optimal genetically programmed PBM, with reduction in the risk of osteoporosis later in life. Intake of nutrients can be estimated through the use of various tools; typically, food-frequency questionnaires (FFQs) are used in epidemiologic studies. The aim of this study was to validate a 21-item, semiquantitative FFQ to assess important nutrient intakes for bone health in Italian schoolchildren 9-10 years of age. Relative validation was accomplished through comparison of the 7-days weighed food record (7D records) with an FFQ developed ad hoc, completed by a group of 75 Italian schoolchildren (36 females, 39 males). Agreement between the two methods was evaluated by Spearman's correlation test and Bland-Altman analysis applied on the data on intake of energy, macronutrients, and micronutrients. Particular attention was devoted to nutrients relevant for bone health. Good correlations between the two methods (FFQ and 7D records) were observed for all nutrients. In particular, mean dietary calcium intakes were 725.6 mg/day (95 % CI 683.2-768.1) from 7D records and 892.4 mg/day (95 % CI 844.6-940.2) from the FFQ. These results indicate that our FFQ for schoolchildren aged 9-10 years is highly acceptable as it is an accurate method that can be used in large-scale or epidemiological studies for the evaluation of nutrient intakes important for the prevention of osteoporosis in a similar population.

UNLABELLED: In order to update data underlying the Italian version of FRAX, we computed the national hip fracture incidence in Italy from hospitalization records for the year 2008. Mortality data and 10-year probabilities of major osteoporotic fractures were also updated. This revision will improve FRAX accuracy and reliability. INTRODUCTION: The original Italian version of FRAX® was based on five regional estimates of hip fracture risk undertaken up to 20 years previously. Our objective was to update hip fracture rates for the model with more recently derived data from the whole Italian population and more recent data on mortality. METHODS: We analyzed the Italian national hospitalization database for the year 2008 in order to compute age- and sex-specific hip fracture incidence rates. Re-hospitalisations of the same patients within 1 year were excluded from the analysis. Hip fracture incidence rates were computed for the age range of 40-100 years, whereas the original FRAX model lacked data on the youngest and oldest age groups. In addition, we used the national mortality data for the same year 2008 to update the model. Ten-year fracture probabilities were re-calculated on the basis of the new fracture incidence rates. RESULTS: The new hip fracture age- and sex-specific incidence rates were close to those used in the original FRAX tool, although some significant differences (not exceeding 25-30 %) were found for men aged 65-75 years and women under 55 years of age. In general, the revision resulted in decreased estimated 10-year probabilities in the younger age groups, whilst those in the older age groups were slightly increased. CONCLUSIONS: The Italian version of FRAX has been updated using the new fracture incidence rates. The impact of these revisions on FRAX is likely to increase the accuracy and reliability of FRAX in estimating 10-year fracture probabilities.

OBJECTIVE: To assess the burden of total joint arthroplasties (TJAs) performed for symptomatic hip and knee osteoarthritis (OA) in the Italian population. METHODS: We analyzed national hospitalizations and diagnosis-related group databases to compute incidence, annual percent change (APC), direct costs, and working days lost between 2001 and 2005 following TJA due to OA. RESULTS: In 2005, we recorded a total of 41,816 (APC +5.4; 95% confidence interval [95% CI] 5.1-5.8) and 44,051 (APC +13.4; 95% CI 13.1-13.8) hip and knee arthroplasties, respectively. Women represented the majority of patients undergoing TJA procedures (female:male ratio 1.7:1 for hip arthroplasties and 2.9:1 for knee arthroplasties). When analyzing the data by age groups, most of the patients were in the age groups 65-74 years and ≥75 years, although the highest increases were observed in those ages <65 years. Revisions accounted for 6,387 (APC +4.9; 95% CI 4.0-5.7) and 2,295 (APC +17.4; 95% CI 15.7-19.2) procedures for the hip and knee, respectively. Loss of working days in patients ages <65 years was estimated between 805,000 and 1 million days. Hospital costs increased from 741 million to 1 billion euros over the 5-year period (from 412 to 538 million euros for hip arthroplasties and from 329 to 517 million euros for knee arthroplasties). Rehabilitation costs increased from 228 to 322 million euros. Postoperative complications were estimated between 3.1 and 4.4 million euros. The average costs per patient were 16,835 and 15,358 euros for hip and knee arthroplasties, respectively. CONCLUSION: The socioeconomic burden of TJAs performed for symptomatic OA in Italy is remarkable and calls for the adoption of proper preventive measures.

UNLABELLED: Aromatase inhibitors (AIs) are widely used in women with breast cancer, but they are known to increase bone loss and risk of fractures. Based on available evidence and recommendations, an ESCEO working group proposes specific guidance for the prevention of AIs-induced bone loss and fragility fractures. INTRODUCTION: Aromatase inhibitors (AIs) are now the standard treatment for hormone receptor-positive breast cancer. However, deleterious effects of AIs on bone health have been reported. An ESCEO working group proposes guidance for the prevention of bone loss and fragility fractures in post-menopausal women with breast cancer receiving AIs. METHODS: A panel of experts addressed the issue of skeletal effects of AIs and effectiveness of antifracture therapies for the prevention of AI-induced bone loss and fractures. Recommendations by national and international organizations, and experts' opinions on this topic were evaluated. RESULTS: All aromatase inhibitors are associated with negative effects on the skeleton, resulting in bone loss and increased risk of fragility fractures. Current guidelines suggest approaches that differ both in terms of drugs proposed for fracture prevention and duration of treatment. CONCLUSION: The ESCEO working group recommends that all AI-treated women should be evaluated for fracture risk. Besides general recommendations, zoledronic acid 4 mg i.v. every 6 months, denosumab s.c., or possibly oral bisphosphonates should be administered for the entire period of AI treatment to all osteoporotic women (T-score hip/spine <-2.5 or ≥ 1 prevalent fragility fracture), to women aged ≥ 75 irrespective of BMD, and to patients with T-score <-1.5 + ≥ 1 clinical risk factor or T-score <-1.0 + ≥ 2 clinical risk factors. Alternatively, therapy could be considered in patients with a FRAX-determined 10-year hip fracture probability ≥ 3%.

INTRODUCTION: There is scarce data available on intra-articular hyaluronan's ability to modify the progression of osteoarthritis (OA). OBJECTIVE: The purpose of this retrospective pilot study was to assess the impact of treatment with hylan G-F 20 on progression to total hip replacement (THR) in patients with symptomatic hip OA. RESEARCH DESIGN AND METHODS: The records of patients presenting with symptomatic hip OA and treated with hylan G-F 20 were analysed. Endpoints were the number of THRs performed and the survival time (in months) between commencement of treatment and THR, if performed. Endpoints were evaluated for the entire study population and for those sub-groups of patients which were, or were not, defined as candidates for THR prior to intra-articular treatment. Predictive factors of progression to THR were also assessed. RESULTS: A total of 850 patients' records were evaluated and 224 patients' data were included in the study and evaluated. Eighty-four patients (37.5%) progressed to THR, 206 patients (92.0%) achieved 12 months survival, 170 patients (75.9%) achieved 24 months survival, and 69 patients (30.8%) achieved 5 years survival. Mean survival time was 36 months. Classification as a THR candidate, Lequesne score, ultrasound pattern and the presence of diabetes were predictive factors for progression to THR. CONCLUSIONS: These results suggest that hylan G-F 20 could be included in the management of symptomatic hip OA before recommendation for THR, particularly in patients presenting with milder symptoms, or in patients where, due to comorbidities or personal choice, THR is not a feasible option. Limitations of this study include the retrospective study design and the lack of a control group to determine any placebo effect of hylan G-F 20. Further prospective studies are therefore needed to corroborate these results.

INTRODUCTION: Non-steroidal anti-inflammatory drugs (NSAIDs) consumption is strictly related to a high gastrointestinal and cardiovascular mortality and morbidity rate. Osteoarthritis Research Society International (OARSI) recommendations in patients with symptomatic hip or knee OA stated that NSAIDs should be used at the lowest effective dose but their long-term use should be avoided if possible. OARSI guidelines for the treatment of the hip OA include the use of viscosupplementation, which aims to restore physiological and rheological features of the synovial fluid. OBJECTIVE: Aim of this multicentric, open and retrospective study is to investigate if NSAID consumption may be reduced by the use of ultrasound-guided intra-articular injection of several hyaluronic acid (HA) products in hip joint administered in patients affected by symptomatic hip OA. MATERIALS AND METHODS: Patients affected by mono or bilateral symptomatic hip OA according to American Rheumatology Association (ARA) criteria, radiological OA graded II-IV (Kellgren and Lawrence) entered the study and were administered with ultrasound-guided intra-articular injection of hyaluronic acid products. As a primary endpoint, consumption of NSAIDs was evaluated by recording the number of days a month (range 0-30) the patient had used NSAID during the previous month, reported at each visit during the 24 months follow-up period. Secondary endpoints included further analysis for subgroups of patients categorized for Lequesne index score, Kellgren-Lawrence score, pain visual analogue scale (VAS) score, ultrasound pattern, age, hyaluronic acid used. RESULTS: 2343 patients entered the study. Regarding primary endpoint, the consumption of NSAIDs was reduced of 48.2% at the third month when compared with baseline values. This sparing effect increased at 12th and 24th month with a reduction respectively of 50% and 61% in comparison to baseline values. These differences were statistically significant. CONCLUSIONS: These data point out that intraarticular hyaluronan preparations provide OA pain relief and reduce NSAIDs consumption in a large cohort of patients for a long period of follow-up. Multiple courses of viscosupplementation (vs) are required to maintain low dose of NSAID consumption over time. NSAIDs consumption is strictly related to an high gastrointestinal and cardiovascular mortality and morbidity rate, instead HA intra-articular treatment is well tolerated and is associated with a low incidence of adverse effects. For these reasons further studies evaluating cost-effectiveness and cost-utility of VS in the management of hip OA are required.

OBJECTIVES: We aimed to analyze incidence and costs of hip fractures in Italy. METHODS: We analyzed the Italian Ministry of Health national hospitalization and DRGs databases concerning fractures occurred in people > or =65 between 2003 and 2005. We have estimated incidence and direct costs sustained by the National Health Service for hospitalization and treatment of hip fractures on the basis of the value of the Diagnosis Related Groups (DRGs) referring to hip fractures. The expenses of rehabilitation and indirect costs were based on regional estimations. RESULTS: Between 2003 and 2005 we registered almost 90,000 hospital admissions per year (corresponding to 75,000 patients) because of hip fractures in people aged > or =65. Women accounted for the majority of hospital admissions due to hip fractures (78.0%; n=214,519). Among women, 84.3% of fractures (n=180,861) occurred in patients > or =75, which is known to be the age group with the highest prevalence of osteoporosis. Hospitalizations of both men and women showed an increasing trend across all the examined period. Hospital costs increased up to 467 million euros in 2005, while rehabilitation costs rose up to 531 million in the same year. CONCLUSIONS: Hip fractures in the Italian population are increasing and represent a major public health challenge.

SUMMARY: A total of 507,671 people > or =65 experienced hip fractures between 2000 and 2005. In 2005, 94,471 people > or =65 were hospitalized due to hip fractures, corresponding to a 28.5% increase over 6 years. Most fractures occurred in patients > or =75 (82.9%; n = 420,890; +16% across 6 years), particularly in women (78.2%; n = 396,967). INTRODUCTION: We aimed to analyze incidence and costs of hip fractures in Italy over the last 6 years. METHODS: We analyzed the national hospitalization and DRG databases concerning fractures occurred in people > or =65 between 2000 and 2005. RESULTS: A total of 507,671 people > or =65 experienced hip fractures across 6 years, resulting in about 120,000 deaths. In year 2005 94,471 people aged > or =65 were hospitalized due to hip fractures, corresponding to a 28.5% increase over 6 years. The majority of hip fractures occurred in patients > or =75 (82.9%; n = 420,890; +16% across 6 years) and particularly in women (78.2%; n = 396,967). Among women, 84.2% of fractures (n = 334,223; +28.0% over 6 years) were experienced by patients > or =75, which is known to be the age group with the highest prevalence of osteoporosis, accounting for 68.6% of the overall observed increase in the total number of fractures. Hip fractures in men > or =75 increased by 33.1% (up to 16,540). Hospitalization costs increased across the six examined years (+36.1%) reaching 467 million euros in 2005, while rehabilitation costs rose up to 531 million in the same year. CONCLUSIONS: Hip fractures of the elderly are increasing and represent a major health problem in industrialized countries such as Italy.

INTRODUCTION: Few data are available about the incidence and costs of hip fractures in Italy. We aimed to determine the impact of hip fractures vs. acute myocardial infarction (AMI). METHODS: We studied the national hospitalization database to calculate their incidence and costs in adults aged >or=45 between 1999 and 2002. RESULTS: In 2002, there were 86,719 hip fractures with a 10.0% increase over 4 years. We observed a predominance of women (77.1%) and a strong age effect: 92.7% of patients were >or=65 years old and 80% of fractures occurred in women aged >or=75, showing a clear relationship with the incidence of osteoporosis. Hospitalizations due to AMI after 45 years of age in 1999 were only 9% higher than those for hip fracture, although this difference increased over the 4 examined years up to 24%. Considering the DRGs costs, hip fractures resulted in being more expensive than AMI overall and concerning elderly people. CONCLUSIONS: This study shows that in the Italian population aged >or=45, hospitalizations following hip fracture and AMI between 1999 and 2002 were comparable, while hip fractures' direct costs were higher and grew faster than costs for AMI. Hip fractures in Italy are a serious medical problem and a leading health-cost driver.

OBJECTIVES: The aim of this study was to evaluate the trend of the incidence and costs of hip fractures in Italy. METHODS: The incidence of hip fractures after 45 years of age in both females and males during the years 1999-2002 was obtained by analyzing the Italian Ministry of Health national hospitalization database, according to the diagnosis codes of International Classification of Diseases, Clinical Modification, 9th edition (IDC-9-CM) that indicate femoral fracture. We have computed all direct costs sustained by the National Health Service for hospitalization and treatment of hip fractures on the basis of the value of the Diagnosis Related Groups (DRG) referring to hip fractures. The expenses of rehabilitation and indirect expenses were based on estimates. RESULTS: In 2002, more than 86,000 hip fractures were registered in Italy in male and female patients over 45 years old, with 9% progression compared to 1999; 77% were female and 80% were over 75 years of age. In 2002 the direct costs of hospitalization, in the patients over 65 years alone, were almost 400 million euros, with an increase of 15% as compared to 1999. Considering also estimated rehabilitation costs, social aid and indirect costs, we estimate that hip fractures due to age-related osteoporosis created over a billion euros in expenses in 2002. CONCLUSIONS: Preventive intervention regarding the risk of hip fracture in elderly patients is urgent.

BACKGROUND: Several trials have just demonstrated the therapeutic efficacy of gabexate mesylate (Foy). For this drug numerous mechanisms of action have been postulated; protease inhibition, direct or indirect lysosomal membrane stabilization, etc. The aim of this study has been to verify if Foy would express antioxidant properties against free radical overgeneration, responsible for the increase in microvascular permeability which represents one of the most important pathogenetic phenomenon of any condition of shock. A mixture of hypoxanthine-xanthine oxidase has been used to obtain a generation of oxygen free radicals in vivo. METHODS: Experiments were performed on the mesocecum of male Wistar rats; fluorescent labelled bovine albumin has been injected intra-arterially to evaluate the capillary permeability and the mesocecum microcirculation has been observed by fluorescent microscopy. The control group received saline i.v., the second group received topically applied on the mesocecum a mixture of 0.96 mM hypoxanthine and 0.05 UI/ml xanthine oxidase; the third and the fourth groups were pretreated respectively with a topical application and continuous infusion of a Foy 1% solution (50 ml/kg/min). To evaluate capillary permeability and to quantify the degree of extravasation by counting the number of leaky sites, labelled bovine albumin was injected i.a. and mesocecum was observed with fluorescent microscopy for 2 hours. RESULTS AND CONCLUSION: Gabexate mesilate (Foy) exerts its efficacy preventing the increase in capillary permeability provoked by an overgeneration of free radicals; it could express antioxidant properties.

BACKGROUND: Circulatory shock, especially endotoxin shock, is characterized by the release of a large number of mediators, among which proteases play a key role. The production of oxygen free radicals into the extracellular space and the increase of capillary permeability is one of the most important consequences of that phenomenon. In order to evaluate the efficacy of gabexate mesilate (Foy) in preventing such increase of microvascular permeability, an experimental model of endotoxin shock was used. MATERIALS AND METHODS: Experiments were performed on the mesocecum of male Wistars rats, fluorescent labeled bovine albumine was injected intrarterially to evaluate the capillary permeability and the mesocecum microcirculation was observed by fluorescent light. The control group received saline i.v.; the II group received a DL 100 of E. coli endotoxin (DIFCO 0111: B4); the III and the IV group received a continuous infusion or topical application of gabexate mesilate respectively, before the administration of endotoxin. To evaluate capillary permeability and to quantify the degree of extravasion by counting the number of leaky sites, fluorescent labelled bovine albumin was injected i.v. and mesocecum was observed with fluorescent microscopy for 2 hours. RESULTS AND CONCLUSIONS: Capillary permeability did not increase in control rats; it largely increased in rats receiving endotoxin i.v. but it did not almost increased in rats receiving gabexate mesilate (Foy) that prevents the increase of capillary permeability that was observed in the group treated with endotoxin alone.
