Microglia derive from mononuclear myeloid progenitors and are a major glial complement of the central nervous system. When microglia are activated they secrete inflammatory cytokines and toxic mediators which amplify the inflammatory response. In addition, the microglia inflammatory products are implicated in the neuronal destruction usually observed in various neurodegenerative diseases. Microglia cells express corticotropin releasing hormone (CRH) receptors, and activation of microglia by CRH releases bioactive molecules which have a biological effect in the brain and regulate several neurological diseases. CRH plays a pivotal role in stress responses and is a key mediator of the hypothalamic-pituitary-adrenocortical system. CRH is expressed in human mast cells, leading to autocrine effects and participates in inflammatory response together with neuropeptides, and stimulates mast cells. IL-33-activated mast cells release vascular endothelial growth factor in response to CRH and act synergistically to increase vascular permeability. CRH also up-regulates IL-18 expression by increasing intracellular reactive oxygen in microglia cells. Here we report the relationship between CRH, microglia and mental disorders.

Chronic Myeloid Leukaemia (CML) shows an excellent response to allogeneic bone marrow transplantation (BMT) with a 60-80% long term disease free survival in recipients of unmanipulate marrow. The most frequent cause of treatment failure is leukaemic relapse, due to the re-emergence of malignant recipient clones. Clinical and haematological relapse is usually preceded by molecular evidence of relapse. Early detection of molecular relapse may allow intervention with immunotherapy such as donor lymphocyte infusions (DLI). This study was undertaken to compare results from two centres who employ either Fluorescent In Situ Hybridisation (FISH) or polymerase chain reaction (PCR) analysis of DNA polymorphisms as their routine method of detecting residual host cells following BMT for CML in order to establish (1) if these methods are equivalent for routine laboratory use in reporting of chimaerism results to the referring clinician, and (2) if these methods are beneficial for indicating new and early therapeutic strategies. FISH analyses for the X and Y chromosomes (in sex mismatched patients) and/or FISH for BCR and ABL loci were compared with short tandem repeat PCR (STR-PCR) and conventional karyotyping in serial analyses in 25 patients submitted to BMT for Philadelphia positive (Ph) CML. Comparison of all results on samples assessed between 1 and 13 years post BMT indicated that FISH and PCR, performed on the same bone marrow samples displayed similar results in more than 90% of patients in first 3 years after BMT which increased to a concordance rate of 100% in long term survivors. In contrast, comparison of FISH or PCR versus cytogenetic analysis indicated a low concordance rate, with less than 50% of samples showing similar results during all the follow-up period. Eighty percent of recipients (22 patients) had evidence of mixed chimaerism following BMT (initial level of positivity 1-6% recipient cells) during the follow-up period. This low percentage of recipient cells remained stable in 7 patients, while 9 patients reverted to a donor profile. All 16 patients are in haematological remission. In addition the 3 patients with complete donor chimaerism remain in remission. In the remaining 6 patients, a progressive increase in recipient cells occurred (progressive mixed chimaerism, PMC), and was followed by haematological relapse. We conclude that FISH and PCR can be used to monitor CML patients post BMT and transient or stable low level mixed chimaerism is not associated with leukaemia relapse, but PMC is predictive of imminent relapse and its detection may help to illucidate the timing of early intervention with donor lymphocyte infusion.

Mast cells (MCs) derive from a distinct precursor in the bone marrow and are predominantly found in tissues at the interface between the host and the external environment where they can secrete mediators without overt degranulation. Mast cells mature under local tissue microenvironmental factors and are necessary for the development of allergic reactions, through crosslinking of their surface receptors for IgE (FcRI), leading to degranulation and the release of vasoactive, pro-inflammatory and nociceptive mediators that include histamine, pro-inflammatory and anti-inflammatory cytokines and proteolytic enzymes. Multiple sclerosis (MS) is an autoimmune disease characterized by inflammatory demylination within the central nervous system. MCs are involved in the pathogenesis of MS by generating various vasoactive mediators and cytokines and participate in the destruction of the myelin sheath and the neuronal cells. The process of the development of demyelinating plaques in MS is probably linked with the rupture of the blood-brain barrier by MC products. The effects of natalizumab, which is a very effective drug in reducing the annualized relapse rate and other relapse-based endpoints, are discussed. Here, we report the relationship between MCs and MS.

Serotonin (5-HT) is an important neurotransmitter that acts in both central and peripheral nervous system, and has an impact on cell proliferation, migration and apoptosis. 5HT exerts its effects via several receptors. Treatment with anti-5-HT receptors diminish the severity of contact allergy in experimental animals, an effect mediated by mast cells; while an agonist reduces the stress level and relieves pruritus in patients with atopic dermatitis. Mast cells are important for both innate and adaptive immunity and they are activated by cross-linking of FceRI molecules, which are involved in the binding of multivalent antigens to the attached IgE molecules, resulting in a variety of responses including the immediate release of potent inflammatory mediators. Serotonin is present in murine mucosal mast cells and some authors reported that human mast cells may also contain serotonin, especially in subjects with mastocytosis. Here we report the interrelationship between mast cells, serotonin and its receptor inhibitor.

It is well established that mast cells, which are found in the tissues in the proximity of small blood vessels and post-capillary venules, play a key role in the early phase of IgE-mediated allergic reactions. A greatly expanded understanding of the biology of IL-3 has emerged since the early 1980s. IL-3 is a specific factor that stimulates the growth of hematopoietic stem and progenitor cells of a variety of lineages and can promote the proliferation of certain classes of lymphocytes distinct from those that are dependent on IL-2. IL-3 has been identified among the most important cytokines for regulation of mast cell growth and differentiation, migration and effector function activities of many hematopoietic cells. IL-3 termed multi colony-stimulating-factor (multi-CSF) or mast cell growth factor (MCGF) is a haematopoietic growth factor which stimulates the formation of colonies for erythroid, megakaryocytic, granulocytic and monocytic lineages. It is predominantly produced by activated T cells, natural killer (NK) cells and mast cells and supports the growth-promoting effects of SCF on mast cell precursors. IL-3 causes severe hypersensivity reactions and plays a pivotal role in exacerbating the inflammatory response in vivo. Here we report the interrelationship between IL-3 and mast cells.

Objective: HIV infection has been associated with increased cardiovascular risk. Twenty-four-hour ambulatory blood pressure (BP) is a more accurate and prognostically relevant measure of an individual's BP load than office BP, and the ambulatory BP-derived ambulatory arterial stiffness index (AASI) and symmetric AASI (s-AASI) are established cardiovascular risk factors. Methods: In the setting of the HIV and HYpertension (HIV-HY) study, an Italian nationwide survey on high BP in HIV infection, 100 HIV-infected patients with high-normal BP or untreated hypertension (72% men, age 48 ± 10 years, BP 142/91 ± 12/7 mmHg) and 325 HIV-negative individuals with comparable age, sex distribution, and office BP (68% men, age 48 ± 10 years, BP 141/90 ± 11/8mmHg) underwent 24-h ambulatory BP monitoring. Results: Despite having similar office BP, HIV-infected individuals had higher 24-h SBP (130.6 ± 14 vs. 126.4 ± 10 mmHg) and pulse pressure (49.1 ± 9 vs. 45.9 ± 7mmHg, both P < 0.001), and a lower day-night reduction of mean arterial pressure (14.3 ± 9 vs. 16.3 ± 7%, P = 0.025). Both s-AASI and AASI were significantly higher in HIV patients (s-AASI, 0.22 ± 0.18 vs. 0.11 ± 0.15; AASI, 0.46 ± 0.22 vs. 0.29 ± 0.17; both P <0.001). In a multivariate regression, s-AASI was independently predicted by HIV infection (β = 0.252, P <0.001), age, female sex, and 24-h SBP. In HIV patients, s-AASI had an inverse relation with CD4+ cell count (Spearman's ρ -0.24, P = 0.027). Conclusion: Individuals with HIV infection and borderline or definite hypertension have higher symmetric AASI and 24-h systolic and pulse pressures than HIV-uninfected controls matched by office BP. High ambulatory BP may play a role in the HIV-related increase in cardiovascular risk. © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins.

BackgroundWe aimed to assess the prevalence of hypertension in an unselected human immunodeficiency virus (HIV)-infected population and to identify factors associated with hypertension prevalence, treatment, and control.METHODSWe used a multicenter, cross-sectional, nationwide study that sampled 1,182 unselected, consecutive, HIV-infected patients. Office blood pressure was accurately measured with standard procedures.RESULTS Patients were 71% men and 92% white, with a median age of 47 years (range = 18-78); 6% were antiretroviral treatment naive the overall prevalence of hypertension was 29.3%; high-normal pressure accounted for an additional 12.3%. Among hypertensive subjects, 64.9% were aware of their hypertensive condition, 52.9% were treated, and 33.0% were controlled (blood pressure < 140/90mm Hg). Blood pressure-lowering medications were used in monotherapy in 54.3% of the subjects. Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers were the most frequently used drugs (76.1%: monotherapy = 39.1%, combination treatment = 37.0%). In multivariable regression models, hypertension was independently predicted by traditional risk factors, including age ≥50 years, male sex, family history of cardiovascular disease, body mass index ≥25kg/m2, previous cardiovascular events, diabetes, central obesity, and metabolic syndrome, as well as by duration of HIV infection, duration of antiretroviral therapy, and nadir CD4+ T-cell count <200/μl the choice of protease inhibitors vs. nonnucleoside reverse transcriptase inhibitors as a third antiretroviral drug was irrelevant. CONCLUSIONSHypertension affects nearly 30% of HIV adult outpatients in Italy. More than one-third of the hypertensive subjects are unaware of their condition, and more than two-thirds are uncontrolled. A higher level of attention to the diagnosis and treatment of hypertension is mandatory in this setting. © 2013 American Journal of Hypertension, Ltd.

Cardiovascular risk profile was compared in 765 Italian HIV-infected outpatients enrolled in 2005 and in 765 individually age-matched and sex-matched patients enrolled in 2011. Median Framingham risk score was 8.6% in 2005 vs. 7.9% in 2011 (PS=S0.04); metabolic syndrome was present in 40.3% vs. 33.4% (PS=S0.006). Blood glucose, triglycerides, prevalence of smokers, and lipodystrophy were all significantly lower in 2011 (all PS0.0001). Cardiovascular risk improved over a 6-year period in Italian HIV-infected patients. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Background: This study evaluated the sealing capacity and safety of a new fibrin sealant (FS) to reduce alveolar air leaks (AALs) after pulmonary resections in a randomized controlled clinical trial conducted in 3 Italian centers. Methods: The study randomized (1:1) 185 patients with an intraoperative AAL graded 1 to 3 according to the Macchiarini scale: 91 received FS and 94 had standard lung closure. The primary outcomes were the length of postoperative AAL duration and the mean time to chest drain removal. Other end points included the percentage of patients without AAL, the development of serum antibodies against bovine aprotinin, and any adverse event related to FS. Chest drains were removed when fluid output was 100 mL/day or less, with no air leak. Results: The study groups were comparable with respect to demographic variables and surgical procedures. The FS group showed a statistically significant reduction in duration of postoperative AALs (9.52 vs 35.8 hours; p < 0.005) and in the percentage of patients with AALs at wound closure (81.11% vs 100%; p < 0.001); the difference in time to chest drain removal was not significant. Pleural empyema developed in 1 patient with FS treatment vs in 4 with standard treatment, and antibodies against bovine aprotinin were found in 34 of 91 FS-treated patients. Conclusions: The present study showed that the new FS is safe and effective in preventing AALs after lung resections and in shortening the duration of postoperative AALs. © 2011 The Society of Thoracic Surgeons.

Purpose: The aim of the study was to evaluate the efficacy of an injectable and partly absorbable calcium bone cement (CERAMENT™, Bone Support, Sweden) in the treatment of osteoporotic or traumatic vertebral fractures by percutaneous vertebroplasty. Methods: From March 2009 to October 2010 an open, prospective study in two centres was performed. 33 patients with symptomatic vertebral fractures were enrolled. Patients were included based on evaluation by X-ray, CT, and MRI. Clinical evaluation by Visual Analogue Scale (VAS, 0-10) and Oswestry Disability index test (ODI, 0-100 %) was performed before the operation as well as 1, 6 and 12 months after the procedure. Radiology assessment post-procedure was carried out by X-ray, CT, and MRI at 1, 6 and 12 months post-op. Intake of analgesic medications pre- and post-procedure was monitored. Results: 66 vertebral bodies underwent percutaneous vertebroplasty. VAS score demonstrated a significant decrease from 8.61 (SD 19.8) pre-operatively to 2.48 (SD 2.36) at 1 month. The score was 2.76 (SD 2.68) at 6 months and 1.36 (SD 1.33) at the latest follow up. ODI score dropped significantly from 58.86 pre-op to 26.94 at 6 months and further down to 7.61 at 12 months. No refractures or adjacent level fractures were reported. Conclusion: Data show that CERAMENT can be a substitute of PMMA in the treatment of osteoporotic and traumatic vertebral fractures, especially in young patients. © Springer-Verlag 2012.
