The Influence of Iron-Deficiency Anaemia (IDA) Therapy on Clinical Outcomes and Healthcare Resource Consumptions in Chronic Kidney Disease Patients Affected by IDA: A Real-Word Evidence Study among the Italian Population.

Anaemia is a uraemia-related complication frequently found in non-dialysis-dependent chronic kidney disease (ND-CKD) patients, with iron-deficiency anaemia (IDA) as the main underlying mechanism. Given the suboptimal anaemia management in ND-CKD patients with a co-diagnosis of IDA, this study evaluated the role of IDA therapy on clinical outcomes and healthcare resource consumptions in an Italian clinical setting. A retrospective observational real-world analysis was performed on administrative databases of healthcare entities, covering around 6.9 million health-assisted individuals. From January 2010 to March 2019, ND-CKD patients were included and diagnosed with IDA in the presence of two low-haemoglobin (Hb) measurements. Patients were divided into IDA-treated and untreated, based on the prescription of iron [Anatomical-Therapeutic Chemical (ATC) code B03A] or anti-anaemia preparations (ATC code B03X), and evaluated during a 6-month follow-up from the index date [first low haemoglobin (Hb) detection]. IDA treatment resulted in significantly decreased incidence of all cause-related, cardiovascular-related, and IDA-related hospitalizations (treated vs. untreated: 44.5% vs. 81.8%, 12.3% vs. 25.3%, and 16.2% vs. 26.2%, respectively, p < 0.001). A healthcare direct cost estimation showed that overall mean expenditure per patient reduced by 47% with IDA treatment (5245€ vs. 9918€, p < 0.001), mainly attributable to hospitalizations (3767€ vs. 8486€, p < 0.001). This real-life analysis on Italian ND-CKD-IDA patients indicates that IDA therapy administration provides significant benefits in terms of patients' clinical outcomes and healthcare cost savings.

Immune endocrinological evaluation in patients with severe vascular acquired brain injuries: therapeutical approaches.

It is known that in severe acquired brain injuries there is process of neuroinflammation, with the activation of a local and general stress response. In our study we considered six patients with disorders of consciousness (five in vegetative state and one in minimal consciousness state) in subacute phase, which had both a clinical assessment and a functional imaging (fMRI): in all these patients we analised blood levels of osteopontin (OPN), a cytokin involved in neuroinflammation but also in neurorepair with a still discussed role. Besides we studied the lymphocyte subsets and blood levels of some hormones (ADH, ACTH, PRL, GH, TSH, fT3, fT4). We found a positive correlation between the levels of serum osteopontin (higher than normal in all subjects) and the severity of the brain injury, especially for prognosis: actually, the patient with the lowest level has emerged from minimal consciousness state, while the one with the highest level has died a few days after the evaluation. The lymphocyte subset was altered, with a general increase of CD4+/CD3+ ratio, but without a so strict correlation with clinical severity; the only hormone with a significant increase in the worse patients was prolactin. In fMRI we detected some responses to visual and acoustic stimuli also in vegetative states, which had no clinical response to this kind of stimulation but generally have had a better prognosis. So we conclude that osteopontin could be a good marker of neuroinflammation and relate to a worse prognosis of brain injuries; the lymphocyte alterations in these disorders are not clear, but we suspect an unbalance of CD4 towards Th2; PRL is the best endocrinological marker of brain injury severity; fMRI surely plays an important role in the detection of subclinical responses and in prognostic stratification, that is still to define with more studies and statistical analysis.

Immunopharmacology of the main herbal supplements: a review.

It is debated whether the use of herbal supplements in endurance sports, in order to have a better performance, is correct or not, from the perspective of both as safety and as effectiveness. In this review we try to find out if the most common herbal supplements (Echinacea, Rhodiola, Ginseng) are effective in the improvement of performance or in the modulation of the immune system. According to the results of our review, the prevalent effect is adaptogenic rather than ergogenic, with a better tolerance of the exercise induced stress, related to enhancement of the whole immune system and decrease of the oxidative damage.
