Journal of Biomedical Science and Engineering (JBiSE) , 2019, DOI: 10.4236/jbise.2019.127028
Abstract: Background: Citicoline and homotaurine are compounds with a potent neuroprotective activity and they have been administered for many years in the treatment of numerous neurodegenerative and ophthalmological diseases, including glaucoma. Initially available only as liquid form, through parenteral route, nowadays citicoline can be administered also as tablet but no data on bioavailability of these different forms are available. In the present study, pharmacokinetics of citicoline in tablet versus vials, each at the therapeutic dose of 500 mg, in addition to 50 mg of homotaurine was investigated. Materials and methods: Ten mixed breed dogs received a single dose of 50 mg oral homotaurine and 500 mg citicoline in tablet and vials with the same dose were administered after a seven days wash-out period. Parameters assessed for citicoline metabolites (cytidine, uridine and choline) were AUC0t, Cmax and Tmax. Results: Citicoline bioavailability appeared to be slightly higher for the tablet compared to the vial formulation. Cytidine is equivalent in absorption dynamics both for tablet and liquid form; uridine for tablet reaches its maximum and is reabsorbed more quickly while choline for the liquid form reaches the maximum first and is reabsorbed more quickly. Conclusions: Citicoline in tablet and liquid formulation have pharmacokinetic properties leading to a very similar bioavailability.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0047059
Abstract: Background Obstructive sleep apnea (OSA) and metabolic syndrome, both closely related to obesity, often coexist in affected individuals; however, body mass index is not an accurate indicator of body fat and thus is not a good predictor of OSA and other comorbidities. The aim of this study was to investigate whether the occurrence of OSA could be associated with an altered body fat distribution and a more evident cardio metabolic risk independently from obesity and metabolic syndrome. Methods and Results 171 consecutive patients (58 men and 113 women) were included in the study and underwent overnight polysomnography. Anthropometric data, blood pressure, lipid profile, glycaemic parameters were recorded. Body composition by DXA, two-dimensional echocardiography and carotid intima/media thickness measurement were performed. 67 patients (39.2%) had no OSA and 104 (60.8%) had OSA. The percentage of patients with metabolic syndrome was significantly higher among OSA patients (65.4%) that were older, heavier and showed a bigger and fatter heart compared to the control group. Upper body fat deposition index , the ratio between upper body fat (head, arms and trunk fat in kilograms) and lower body fat (legs fat in kilograms), was significantly increased in the OSA patients and significantly related to epicardial fat thickness. In patients with metabolic syndrome, multivariate regression analyses showed that upper body fat deposition index and epicardial fat showed the best association with OSA. Conclusion The occurrence of OSA in obese people is more closely related to cardiac adiposity and to abnormal fat distribution rather than to the absolute amount of adipose tissue. In patients with metabolic syndrome the severity of OSA is associated with increase in left ventricular mass and carotid intima/media thickness.
From rehabilitation to remission in ankylosing spondylitis
E. Lubrano,A. Spadaro
Reumatismo , 2011, DOI: 10.4081/reumatismo.2009.241
Abstract: During the past years, exercise and non-steroidal anti-inflammatory drugs (NSAIDs) have been the mainstay of symptom control for Ankylosing Spondylitis (AS), a chronic, inflammatory rheumatic disease characterized by inflammatory back pain due to sacroiliitis and spondylitis. The ASsessment in AS (ASAS) international working group has constructed evidence based recommendations to guide the physician in the management of AS (1). Among the major recommendations for the management of AS, the ASAS group stated that there is a level Ib evidence that NSAIDs improve spinal pain, peripheral joint pain, and function, but comparative studies (1) or population-based survey (2) of different NSAIDs/coxib have not demonstrated one preparation to be clearly better than the others. Wanders et al (3) showed that the clinical efficacy of continuous NSAIDs/coxib treatment for AS was similar to intermittent ‘‘on demand’’ use and they suggested that the continuous treatment with NSAIDs/coxib could slow the radiographic disease progression over 2 years...
Psoriatic arthritis: treatment strategies using anti-inflammatory drugs and classical DMARDs
E. Lubrano,R. Scarpa
Reumatismo , 2012, DOI: 10.4081/reumatismo.2012.107
Abstract: Psoriatic Arthritis (PsA) is a chronic inflammatory disease typically characterized by arthritis and psoriasis variably associated with other extra-articular manifestations. PsA has been considered a milder and less disabling disease compared with rheumatoid arthritis (RA), even if some studies showed that PsA had joint erosions and damage. In addition, about 20-40% of PsA patients have axial skeleton involvement that may lead to functional limitation and deformity. The treatment of PsA ranged from initial treatment with non-steroidal anti-inflammatory drugs (NSAIDs) to one or more disease-modifying anti-rheumatic agents (DMARDs) for the suppression of inflammation in patients with recalcitrant peripheral joint disease. In clinical practice, the most widely used DMARDs are methotrexate (level of evidence B), sulfasalazine (level of evidence A), leflunomide (level of evidence A), and ciclosporin (level of evidence B). However, the efficacy of these agents in inhibiting joint erosions has not been assessed in controlled studies. Finally, the effectiveness of DMARDs in treating enthesitis and dactylitis is controversial. The present paper revised the evidence-based results on treatment with “conventional” therapy for PsA. The revision was based on all the subsets of the diseases, namely the various manifestations of the articular involvement (peripheral, axial, enthesitis, dactylitis) as well as the skin and nail involvement.
Psoriatic arthritis: imaging techniques
A. Spadaro,E. Lubrano
Reumatismo , 2012, DOI: 10.4081/reumatismo.2012.99
Abstract: Imaging techniques to assess psoriatic arthritis (PsA) include radiography, ultrasonography (US), magnetic resonance imaging (MRI), computed tomography (CT) and bone scintigraphy. The radiographic hallmark of PsA is the combination of destructive changes (joint erosions, tuft resorption, osteolysis) with bone proliferation (including periarticular and shaft periostitis, ankylosis, spur formation and non-marginal syndesmophytes). US has an increasing important role in the evaluation of PsA. In fact, power Doppler US is useful mainly for its ability to assess musculoskeletal (joints, tendons, entheses) and cutaneous (skin and nails) involvement, to monitor efficacy of therapy and to guide steroid injections at the level of inflamed joints, tendon sheaths and entheses. MRI allows direct visualization of inflammation in peripheral and axial joints, and peripheral and axial entheses, and has dramatically improved the possibilities for early diagnosis and objective monitoring of the disease process in PsA. MRI has allowed explaining the relationships among enthesitis, synovitis and osteitis in PsA, supporting a SpA pattern of inflammation where enthesitis is the primary target of inflammation. CT has little role in assessment of peripheral joints, but it may be useful in assessing elements of spine disease. CT accuracy is similar to MRI in assessment of erosions in sacroiliac joint involvement, but CT is not as effective in detecting synovial inflammation. Bone scintigraphy lacks specificity and is now supplanted with US and MRI techniques.

Modern Research in Inflammation (MRI) , 2012, DOI: 10.4236/mri.2012.11002
Abstract: Objectives: Smoking increases oxidative modification of LDL, associated with lower HDL plasma levels, systemic inflammatory response and endothelial dysfunction. We tested the hypothesis that the risk status for coronary atherosclerosis disease (CAD) of cigarettes smokers might be identified by means of serum oxidative levels and vascular inflammation determination. Design and Methods: Oxidative stress levels, cytokines, and the metabolic status were investigated on 499 subjects admitted to our institute. The association between biomarkers and smoking habits in the presence/absence of disease and with the number of vessel affected, was studied. Results: Oxidative stress and inflammatory levels (p < 0.001) were strongly induced by smoking habits. Serum values of the subjects categorised as CAD, non CAD and healthy subjects differed significantly (p < 0.001) only for the degree of oxidative stress. Glycaemia was able to affect C-reactive protein serum levels with a positive association (p < 0.05). The analysis of the study population indicated that serum oxidative stress levels significantly increased with increasing number of vessels affected (p < 0.01). When statistical analysis was performed separately in both smoking groups, smokers did not show any particular difference for both oxidative stress and inflammation markers between the two groups of cardiovascular patients (CAD and non CAD) and the control group, while for non smokers, the differences were evident. Conclusion: These findings indicate that the considered biomarkers, especially oxidative stress, can be useful to predict the biological damage caused by cigarette smoking, as well as to identify subjects characterised by a higher risk of cardiovascular event, but cannot evaluate the presence of disease in subjects with smoking habit.
Complementary medicine in rheumatoid arthritis
P. Sarzi- Puttini,F. Atzeni,E. Lubrano
Reumatismo , 2011, DOI: 10.4081/reumatismo.2005.226
Abstract: Use of complementary and alternative medicine (CAM) for chronic conditions has increased in recent years. CAM is immensely popular for musculoskeletal conditions and patients suffering from rheumatoid arthritis (RA) frequently try CAM. This review summarises the trial data for or against CAM as a symptomatic treatment for rheumatoid arthritis. Collectively the evidence demonstrates that some CAM modalities show significant promise, e.g. acupuncture, diets, herbal medicine, homoeopathy, massage, supplements. However, for the great majority of these therapies no evidencebased (clinical randomized trials) results are available. CAM is usually used in addition to, and not as a substitute for conventional therapies. The motivation of patients to try CAM is complex; the willingness to take control of their healthcare, the desire to try everything available, the mass-media pressure and the erroneous notion that CAM is without risks. In fact, none of these treatments is totally devoid of risks. While the use of complementary and alternative modalities for the treatment of RA continues to increase, rigorous clinical trials examining their efficacy are needed before definitive recommendations regarding the application of these modalities can be made.

Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.520213
Abstract: Obesity and sarcopenia combination, appropriately defined as sarcopenic obesity (SO), due to disproportionally reduced/low lean body mass compared to excess fat mass, may lead to disability. Aims: The aim of our study was to investigate the relationship among sarcopenic obesity, physical performance, disability, and quality of life in a rehabilitation setting. Methods: Participants were recruited among obese patients (BMI > 30 kg/m2) admitted to the rehabilitation facility at the Department of Experimental Medicine, Medical Physiopatology, Food Science and Endocrinology Section during a 1-year period. A multidimensional evaluation was performed through bioelectrical impedance analysis and anthropometry, handgrip strength test, Short Physical Performance Battery (SPPB), 6-minute walk test (6MWT) and blood chemistry parameters. Psychological status (SCL-90 questionnaire), quality of life, and comorbidity (Charlson comorbidity index score) were also evaluated. Obesity was diagnosed as increased fat mass by 35% in women and by 25% in men. Sarcopenia was defined if lean body mass (LBM) was <90% of the subject’s ideal LBM. Results: 79 patients (48 women and 31 men; mean age: 60.1 ± 11.5 years, and 58.6 ± 10.8 years, respectively) were enrolled. Results showed a high prevalence of SO (54.4%) in our samples of obese subjects. Sarcopenia was present not only among older obese adults but also among younger obese subjects, and was related to reduced functional performance, to inflammatory status and to worse psychological status and quality of life.
Supercritical Fluid Adsorption of Domperidone on Silica Aerogel  [PDF]
Giuseppe Caputo
Advances in Chemical Engineering and Science (ACES) , 2013, DOI: 10.4236/aces.2013.33024
Abstract:

Silica aerogel (SA) was loaded with domperidone to demonstrate the potentiality of adsorption processes based on the usage of supercritical carbon dioxide to treat poorly water-soluble drugs, forming new kinds of drug delivery systems. The effects of pressure, temperature and solution concentration on loaded SA were studied. Adsorption isotherms were measured at 35and 45 and fitted with Langmuir model. Release kinetics of the adsorbed drug were also evaluated by in vitro dissolution tests. Results showed that domperidone can be uniformly dispersed into the aerogel and that the release rate of domperidone from the composite, constituted by drug and silica aerogel, is much faster than that of the crystalline drug. The proposed adsorption method is suitable for the production of domperidone fast release tablets.
