Cilostazol reduces dry eye symptoms and improve walking distance in patients with peripheral artery disease.

AIM OF THE STUDY: Cilostazol is a phosphodiesterase III inhibitor that has anti-inflammatory and immunomodulatory effects and can act with beneficial effect in Dry Eye Syndrome (DES). This clinical trial evaluates the effects of cilostazol on the tear film. MATERIALS AND METHODS: Following the run-in period, subjects were randomly into two groups: 40 subjects treated with cilostazol and 40 no-treated subjects. The Walking Impairment Questionnaire (WIQ) has been administered to all patients. RESULT: The data obtained from comparison of the two study groups A and B were, respectively, the following: Schirmer I: 10.2±0.2 Vs 13.8±0.4 (p< 0.001); Schirmer II: 3.8±0.1 Vs 4.6±0.2 (p<0.001); Break-up time (BUT) 4.2±0.3 Vs 6.5±0.2 (p<0.001) with disappearing of symptoms. The WIQ showed a significant difference in the walking distance (p<0.05) and calf pain severity (p<0.005) of treated patients. In comparison with the placebo group, treated patients showed an improvement (p<0.03) in calf pain severity. CONCLUSION: The administration of cilostazol was effective, in reducing DES and improve walking distance questionnaire.

Static postural control disturbances among the different multiple sclerosis phenotypes: A Neurocom Balance Manager® evaluation study.

BACKGROUND: The computerized stabilometric platform can be used and privileged over clinical scales, as self-administered questionnaires to asses postural control and balance evaluation in Multiple sclerosis (MS). Aim of our study was to evaluate static postural control assessed by Neurocom Balance Manager® through the modified Clinical Test of Sensory Interaction on Balance (mCTSIB) in relapsing-remitting MS (RRMS), progressive MS (PMS) and CIS, compared to healthy controls (HC). METHODS: We screened MS patients consecutively referring to our MS Center at University of Catania, during July 2013-June 2014 diagnosed as CIS, RRMS and PMS. All MS patients underwent clinical and neurological evaluations and a complete postural exam by Neurocom Balance Manager® in order to evaluate Center of Pressure (COP), through mCTSIB. We evaluated the following parameters: Total Path Length-open eyes (TPL-OE), Total Path Length-closed eyes (TPL-CE), Sway Area-open eyes (SA-OE), Sway Area-closed eyes (SA-CE), Mean sway velocity-open eyes (MSV-OE), Mean sway velocity-closed eyes (MSV-CE). Additionally, patients were tested by Berg balance scale (BBS) for balance and Barthel Index (BI) for disability outcomes. RESULTS: Out of 170 MS patients assessed for eligibility, 163 met the inclusion/exclusion criteria and were finally enrolled. All balance parameters were found more impaired in MS group compared to controls and CIS. Moreover, no differences in terms of balance assessment were found between HC and CIS. The correlation analysis showed that BBS was strongly associated to SA-OE, SA-CE, TPL-OE and MSV-OE. We also found a correlation between BI and SA-CE. CONCLUSION: Our study revealed significant differences among HCs, CIS and MS. MS, especially PMS, exhibit the worst balance performances especially in EC trials. The higher correlation between balance parameters, especially sway area, and BBS score confirmed the reliability and sensibility of mCTSIB assessment in evaluating static postural control in MS patients.

Late-onset and young-onset relapsing-remitting multiple sclerosis: evidence from a retrospective long-term follow-up study.

BACKGROUND AND PURPOSE: Late-onset multiple sclerosis (MS) has a prevalence of about 10-20% in natural history MS studies. Few data have been published about the long-term disease trajectory in the cohort of late-onset relapsing-remitting MS (LORRMS). The aim of this study was to identify the risk factors for reaching an Expanded Disability Status Scale (EDSS) score of 6.0 in LORRMS (onset at >40 years of age) and young-onset relapsing-remitting MS (YORRMS) (onset between 18 and 40 years of age). METHODS: Clinical and radiological [magnetic resonance imaging (MRI) of the brain] follow-up data were collected. Disability was assessed by EDSS score. A Cox proportional hazards model was used to evaluate the demographic and clinical predictors of reaching an EDSS score of 6.0 in the two cohorts. RESULTS: A total of 671 patients with relapsing-remitting MS were enrolled, 143 (21.3%) with LORRMS and 528 (78.7%) with YORRMS. In LORRMS, age at onset was 47.8 ± 5.3 (mean ± SD) years and duration of follow-up was 120.7 ± 52.7 months. In YORRMS, age at onset was 27 ± 2.7 years and duration of follow-up was 149.9 ± 92.7 months. The survival curve analyses showed a higher probability of reaching an EDSS score of 6.0 for LORRMS in a shorter time (months) than for YORRMS (94.2 vs. 103.2 months; log-rank 8.8; P < 0.05). On MRI, YORRMS showed more brain inflammatory features than LORRMS. In the multivariate Cox model, age at onset [Exp(B) value, 6.5; 95% confidence interval, 1.9-22.6; P < 0.001] and male gender [Exp(B) value, 1.7; 95% confidence interval, 1.0-2.8; P < 0.05] were the strongest predictors of reaching an EDSS score of 6.0. CONCLUSIONS: The male population with LORRMS reached severe disability faster than those with YORRMS, even when YORRMS showed more brain inflammatory features on MRI.

Lateral switch to IFN beta-1a 44 mcg may be effective as escalation switch to fingolimod in selected persons with relapsing remitting multiple sclerosis: a real-world setting experience.

BACKGROUND: The efficacy of lateral and escalation switch is a challenge in MS. We compared in a real-world setting the efficacy of switching to IFN beta-1a 44 mcg or to fingolimod in persons with relapsing remitting MS (pwRRMS) who failed with others injectable IFNs or glatiramer acetate. RESEARCH DESIGN AND METHODS: retrospective analysis of 24 months prospectively-collected data at the MS center of the University of Catania, Italy was performed. Patients who were switched to IFN-beta 1a 44 mcg or fingolimod were analyzed using propensity-score covariate adjustment model within demographic (e.g. age and gender) and disease (e.g. timing of pre-switch relapse) characteristics. Switching-time was considered the starting-time of the observation. RESULTS: 43 pwRRMS on IFN beta-1a 44 mcg and 49 pwRRMS on fingolimod were included. Baseline characteristics differed for EDSS score and number of T2 lesions (higher in group on fingolimod). At 24 months of follow up, both groups showed no differences in the survival curves of reaching a first new relapse, new T2 and Gd+ MRI brain lesions, even corrected for the propensity score covariate adjustment. CONCLUSIONS: lateral switch to IFN beta-1a 44 mcg and escalation switch to fingolimod showed same ability in influencing RRMS disease activity at 24 months.

Etiology of chronic skin lesions in subjects with peripheral arterial disease.

INTRODUCTION: Skin lesions can be defined as lesions that result in loss of tissues and their joints, and often this cutaneous skin process is a primary or secondary consequence of the structural changes in the skin itself. Subjects with peripheral arteripathies that develop chronic skin lesions in the lower extremities of the Western world are constantly increasing. We conducted a study on the etiologic incidence of chronic skin lesions in peripheral arterial disease CSLpa subjects in the lower limbs compared to subjects with chronic skin lesions CSL (controls). MATERIALS AND METHODS: 30 subjects with peripheral atheropathies PA (22 F - 8 M mean age 74,5 ± 4,9) and with chronic skin lesions (CSLpa) in the lower limbs "A" group were admitted to our study according to a randomized and compared to 30 no peripheral atheropathies subjects (19 F-11 M, mean age 81,5 ± 7,3 - controls) group B with chronic skin lesions (CSL). These two groups "A" and "B" have been studied and compared on the basis of infectious etiology responsible for the infectious skin process. RESULTS: In the subjects of the "A" group we found a 12 positive assay of 40.0% of the examinations, while in the group "B" we achieved a total cultured positivity of 9 cases corresponding to 30.0% of the examinations . For the number of bacterial species identified for "A" group we obtained 3 mono microbial and 6 poly microbial bacteriological tests and for group "B" we observed 7 mono microbial and 2 poly microbial tests. All bacteriological isolates showed "in vitro" sensitivity to satisfactory ciprofloxacin with MICs range of 0.78-1.56mg/L. The data observed after 4 weeks after the amniotic membrane (MA) in the two study groups A and B were respectively the following: and for group A 50% scarring, 46.6% partial resolution and in one case worsening for the B-healing group in 63.3%, the partial resolution in the remaining 36.6. CONCLUSIONS: The data from this study show a different etiology between subjects with CSLpa than subjects with CSL. This phenomenon confirms an alteration of the skin microbioma of subjects with peripheral arteriopathy and chronic skin lesions with modification of the opportunistic role of some species of cutaneous bacterial flora.

The mixture of bifidobacterium associated with fructo-oligosaccharides reduces the damage of the ocular surface.

BACKGROUND: Despite its high prevalence Dry Eye Syndrome (DES) in frequently under-recognized owing to its negative influence on patients visual function. METHODS: This clinical trial was a pilot study to evaluate the effects of supplementation with mixture (Bifidobacterium lactis and Bifidobacterium bifido) on the tear film. Following the run-in period subjects were randomized in two groups: group A (N°20 subjects) and group B (N°20 subjects). Group A (control) treated only with substitute tear and group B treated with substitute tear + mixture (symbiotic). RESULTS: The data obtained in the two study groups A and B were, respectively the following: Schirmer 9.1±0.2 vs 12.7±0.4 (p< 0.001); Schirmer II 3.5±0.1 VS 4.7±0.2 (p<0.001); BUT 3.9±0.3 vs 6.3±0.2 (p<0.001). Culture test showed initial bacterial growth in group "A" (placebo) 18 out of 40 samples tested, corresponding to 45.0% and "B" after treatment ((symbiotic) was found positive culture whit growth of bacteria in 12 tests equal to 30.0%. The total numbers of isolations of aerobic and anaerobic bacteria found group A and B after treatment. A reduction of 15 to 11 strains of aerobic and anaerobic isolates from 9 to 5 has been found. CONCLUSIONS: The present study shows that the administration of bifidobacterium may represent a success full treatment in ameliorating dry eye syndrome (DES). The effect of imbalanced microbiota are not restricted by gastrointestinal abnormalities but could have systemic impact on immunity. Commensal bacteria or probiotics interact with the endogenous enteric microbiota and gut cells therein confereing health benefit to the host.
