Background: Peripheral neuropathy is among the most common complications among people with HIV with prevalence rates varying widely among studies (10-58%)., Objective: This study aims to assess the prevalence of HIV-associated peripheral neuropathy among HIV-positive people in Northern Greece monitored during the last 5-year period and investigate possible correlations with antiretroviral therapy, disease staging, and potential risk factors, as there is no prior epidemiological record in Greek patients., Methods: Four hundred twenty patients were divided into a group with peripheral neuropathy ( n = 269), and those without ( n = 151). Peripheral neuropathy was assessed with a validated Peripheral Neuropathy Screening tool. Statistical analyses were performed with SPSS, were two-tailed, and p -value was set at 0.05., Results: The incidence of peripheral neuropathy was estimated at 35.9%. Age was found to correlate with higher odds of developing HIV-peripheral neuropathy, rising by 4%/year. Females encountered 77% higher probability to develop peripheral neuropathy. Stage 3 of the disease associated with higher occurrence of peripheral neuropathy (96% as compared to stage-1 patients). Among patients with peripheral neuropathy, the duration of antiretroviral therapy was found to be longer than in those without., Conclusions: Peripheral neuropathy remains one of the most common complications regardless of the antiretroviral-therapy type, indicating the involvement of other risk factors in its occurrence, such as the stage of the disease, age and gender. Therefore, the treating physician should screen patients as early and frequently as possible upon HIV-diagnosis to prevent the progression of this debilitating condition so that prolonged life-expectancy is accompanied by a good quality of life.

Objectives: Adverse neurologic outcome can be a debilitating complication after cardiac surgery. The aim of this study was to investigate the potential neuroprotective action of erythromycin, a well known antibiotic agent, regarding postoperative cognitive decline in patients undergoing cardiac surgery., Methods: Forty patients scheduled for elective coronary artery bypass grafting surgery were prospectively randomly assigned in 2 groups: the erythromycin group (n = 19) who received erythromycin at a dose of 25 mg/kg before and after surgery and the control group (n = 21) who did not receive it. All patients were monitored with near-infrared spectroscopy during the operation. Interleukin (IL) 1 and IL-6 as inflammatory markers and tau protein as a marker of brain injury were measured before and after surgery. Neurocognitive assessment was performed before surgery, on the day of discharge, and at 3 months postoperatively., Results: Both groups were comparable in terms of demographic and clinical data. Patients who took erythromycin presented with significantly better cognitive performance before discharge and 3 months after surgery. No significant differences between the 2 groups referring to IL-1 and IL-6 values were detected. Tau serum values were lower in the erythromycin group after surgery., Conclusions: Erythromycin administration attenuates cerebral damage and postoperative cognitive decline after coronary artery bypass grafting surgery., Trial Registration: The study was retrospectively registered at ClinicalTrials.gov (NCT01274754). Study start day: November 2008.

Background/aims: We assessed the, hitherto unknown, impact of intravenous methylprednisolone (ivMP) pulses during relapses of multiple sclerosis (MS) on the kinetics of anti-interferon-beta neutralizing antibodies (Nabs) and binding antibodies (Babs)., Methods: Babs (ELISA) and Nabs (antiviral cytopathic effect assay) titers were evaluated before, immediately after and at 1 month following ivMP in 60 MS patients., Results: ivMP reduces Nabs and Babs titers for at least 1 month. Baseline titers determine Nabs and Babs seronegativity at the end of ivMP. Clinical response to ivMP tends to be better in Nabs(+) patients., Conclusion: Sampling for Nabs/Babs should be avoided during or shortly after ivMP to avoid transient positive or negative results that may obscure the decision to switch treatment., (© 2016 S.
