Simple Summary: Some cats positive for Leishmania infantum (Li) show clinical signs and clinicopathological changes, including hemogram abnormalities. However, co-infections or co-morbidities are often detected in cats with leishmaniosis, and they can have a role in the clinical abnormalities observed. In feline Leishmania infantum infections and in clinical cases of feline leishmaniosis, a significant association with feline immunodeficiency virus (FIV) has been detected, but the role of this co-infection is controversial. The aims of this study were to retrospectively evaluate hemogram changes in cats from areas endemic for Leishmania infantum and feline immunodeficiency virus infections (Sicily and Calabria regions, Southern Italy) and to analyze the role of both pathogens in the abnormalities detected. A retrospective cross-sectional study was carried out on 496 cats. Hematological changes in cats positive for Leishmania infantum were found, particularly abnormalities compatible with chronic inflammation including moderate anemia, monocytosis, and morphologically activated monocytes. Moreover, some abnormalities, such as thrombocytosis, seem to arise when cats are co-infected with FIV. Feline leishmaniosis should be considered when some hemogram abnormalities compatible with chronic inflammation are detected. In feline Leishmania infantum (Li) infection and in clinical cases of feline leishmaniosis, co-infection with feline immunodeficiency virus (FIV) has been reported. However, the role of the retroviral co-infection in the impairment of feline clinical health is still controversial. The aim of this study was to evaluate hemogram changes in cats from regions endemic for both Li and FIV infection. Four hundred and ninety-six cats tested for Li (EDTA blood polymerase chain reaction and immunofluorescence antibody test) and for FIV infection (enzyme-linked immune assay) were retrospectively evaluated. Hemogram results including blood smear morphological evaluation were statistically compared considering four infection patterns: Li+FIV+, Li+FIV−, Li−FIV+, and Li−FIV−. Significantly lower values of erythrocytes (Li+FIV−: p = 0.0248; Li−FIV+: p = 0.0392) and hemoglobin (Li+FIV: p = 0.0086; Li−FIV+: p = 0.0249) were found in both infections when compared to Li−FIV− cats, and severity of anemia was more frequently moderate in Li-positive cats (p = 0.0206) and severe in FIV infection (p = 0.024). Li infection was associated with monocytosis (p = 0.0013) and morphologically activated monocytes (p = 0.0209). Moreover, FIV infection was associated with the presence of inflammatory leukogram (p = 0.023), and an association between thrombocytosis and the co-infection was found (p = 0.0347). Li infection in cats induces hematological changes compatible with chronic inflammation, some of which are due to co-infection with FIV. [ABSTRACT FROM AUTHOR]

Introduction: The increase of the anti-inflammatory CD163highHLA-DRlow blood monocyte subset is one of the mechanisms dampening inflammation during cardiac surgery with cardiopulmonary bypass. We evaluated the effect of two different anesthetic protocols, intravenous Propofol infusion or Sevoflurane-gas administration, on the perioperative frequency of this subset. Methods: Blood from patients (Propofol = 11, Sevoflurane = 13) undergoing minimally invasive mitral valve surgery was drawn preoperatively (T1), before declamping (T2), at 6 (T3), 24 (T4), 48 (T5), and 72 hours (T6) after declamping. C-reactive protein, haptoglobin, and lactate dehydrogenase were measured. A hemolytic index, as C-reactive protein/haptoglobin ratio, was introduced. Monocyte expression of HLA-DR, CD163, and the CD163highHLA-DRlow subset fraction was quantified by flow cytometry. Baseline-referred variations of plasmatic and cellular data at T2 were normalized for clamping times. Subsequent time-point variations were normalized for the final cardiopulmonary bypass times. Results: Variations of hemolytic index and lactate dehydrogenase were higher with Propofol at T3 (p = 0.004 and p = 0.02, respectively) when compared with Sevoflurane. At T2, the down-modulation of CD163 was higher with Propofol (p = 0.005). Starting from T3, the up-regulatory trend of CD163 was basically higher with Propofol, although not significantly. Propofol induced higher increments of HLA-DR low fractions, at T2 (p = 0.04) and, to a lesser extent, at T4 (p = 0.06). Starting from T3, the CD163highHLA-DRlow subset variations were higher with Propofol, especially at T4 and T6. Conclusion: Propofol seems to induce a higher postoperative fraction of the CD163highHLA-DRlow monocyte subset. This could represent either a compensatory mechanism dampening the higher inflammatory condition observed with Propofol at T2 or a consequence of a higher postoperative Propofol-induced hemolysis.

It is well established that some patients with diffuse large B-cell lymphoma (DLBCL) and the negative end of treatment PET-CT (EOT-PET-CT) will relapse, while a proportion with positive uptake can still obtain long-term EFS. We reviewed data of 200 consecutive, previously untreated patients with DLBCL recorded in Italy and Israel between 2007 and 2015. We found that patients with negative EOT-PET-CT with AMC > 630/mmc have a 3-years EFS of 72%, compared to those with AMC ≤ 630/mmc that have an EFS of 84%. Furthermore, considering patients with positive EOT-PET-CT, those with AMC > 630/mmc have a 3-years EFS of 8%, while those with AMC ≤ 630/mmc have an EFS of 38%. Thus, it appears that combining the gold standard for response evaluation EOT-PET-CT with a simple and inexpensive parameter like AMC at diagnosis, further improves prognostication in DLBCL. Applying this simple method can be useful for all doctors working in lymphoma clinical practice. [ABSTRACT FROM AUTHOR]

OBJECTIVE -- Despite increased information on the importance of an inappropriate inflammatory response in the acute Charcot process, there has been no previous attempt to define the specific pathways that mediate its pathogenesis. Here, the role played by monocytes was analyzed. RESEARCH DESIGN AND METHODS-- The immune phenotype of peripheral monocytes was studied by fluorescence-activated cell sorter analysis comparing patients with acute Charcot (n = 10) in both the active and recovered phase, diabetic patients with neuropathy (with or without osteomyelitis), and normal control subjects. RESULTS -- When compared with diabetic control subjects and healthy subjects, monocytes from acute Charcot patients showed a proinflammatory immune phenotype characterized by increased production of proinflammatory cytokines, reduced secretion of anti-inflammatory cytokines, increased expression of surface costimulatory molecules, and increased resistance to serum withdrawal-induced apoptosis. In addition, the pattern of circulating cytokines confirmed activation of proinflammatory cytokines. No modulation of the monocyte phenotype was documented in diabetic control subjects and healthy subjects, thus indicating that the proinflammatory alterations of monocytes are specific and causative of acute Charcot. CONCLUSIONS -- Together, these data provide evidence for the role of proinflammatory changes in the immune phenotype of monocytes in the pathogenesis of acute Charcot. These alterations may explain the abnormally intense and prolonged inflammatory response that characterizes this disorder and may represent a potential therapeutic target for specific pharmacological interventions.

OBJECTIVE--Monocyte chemoattractant protein-1 (MCP-1), a chemokine binding to the CC chemokine receptor 2 (CCR2) and promoting monocyte infiltration, has been implicated in the pathogenesis of diabetic nephropathy. To assess the potential relevance of the MCP-1/CCR2 system in the pathogenesis of diabetic proteinuria, we studied in vitro if MCP-1 binding to the CCR2 receptor modulates nephrin expression in cultured podocytes. Moreover, we investigated in vivo if glomerular CCR2 expression is altered in kidney biopsies from patients with diabetic nephropathy and whether lack of MCP-1 affects proteinuria and expression of nephrin in experimental diabetes. RESEARCH DESIGN AND METHODS--Expression of nephrin was assessed in human podocytes exposed to rh-MCP-1 by immunofluorescence and real-time PCR. Glomerular CCR2 expression was studied in 10 kidney sections from patients with overt nephropathy and eight control subjects by immunohistochemistry. Both wild-type and MCP-1 knockout mice were made diabetic with streptozotocin. Ten weeks after the onset of diabetes, albuminuria and expression of nephrin, synaptopodin, and zonula occludens-1 were examined by immunofluorescence and immunoblotting. RESULTS--In human podocytes, MCP-1 binding to the CCR2 receptor induced a significant reduction in nephrin both mRNA and protein expression via a Rho-dependent mechanism. The MCP-1 receptor, CCR2, was overexpressed in the glomerular podocytes of patients with overt nephropathy. In experimental diabetes, MCP-1 was overexpressed within the glomeruli and the absence of MCP-1 reduced both albuminuria and downregulation of nephrin and synaptopodin. CONCLUSIONS--These findings suggest that the MCP-1/CCR2 system may be relevant in the pathogenesis of proteinuria in diabetes. Diabetes 58:2109-2118, 2009 [ABSTRACT FROM AUTHOR]

• LLIs (median age 97) from the Southern Italy display a peculiar cytokine profile. • TARC and IP-10 are increased in the LLIs'plasma. • TARC is uniquely instrumental to drive human monocytes toward a M2 macrophage state. A way to delay aging and the related low-grade chronic inflammatory state is to study the model of positive physiology such as the Long-Living Individuals (LLIs). Our recent studies have shown higher levels of the host defense BPI Fold-Containing Family B Member 4 (BPIFB4) protein in the LLIs' blood. Notably, BPIFB4 has been shown to influence monocytes typesetting and M2 anti-inflammatory phenotype (CD206+CD163++) macrophages skewing. According to the role of a complex cytokine milieu in guiding the macrophage polarization, here we found that circulating concentrations of thymus and activation regulated chemokine (TARC)/CCL17 and small-inducible cytokine B10 (IP-10)/CXCL10) cytokines, were additionally associated with the LLIs' state. In a differentiation process in vitro , the addition of LLIs' plasma to the cell culture medium, enhanced the ability of monocytes, either from LLIs or controls, to acquire a M2 phenotype. Interestingly, a neutralizing antibody against TARC blunted the M2 skewing effect of the LLIs' plasma. Collectively, these data indicate that exceptional longevity may associate with a peculiar anti-inflammatory myeloid profile responsible for improved reparative processes and reduced inflammatory status mediated in part by TARC and M2 generation.

Background and Aims: In the present study, we aimed to compare the clinical and coronary angiography features between South Asian and Caucasian patients with Acute Coronary Syndrome (ACS). In particular, we focused our analysis on the evaluation of recent cardiovascular risk markers, such as remnant cholesterol, corresponding to all plasma cholesterol minus HDL-C (high-density lipoprotein cholesterol) and LDL-C (low-density lipoprotein cholesterol), and the Monocyte-to-HDL-cholesterol ratio. We also compared values of several lipoprotein ratios and the Platelet-to-lymphocyte ratio, accurate predictors of coronary events and coronary artery disease., Methods and Results: We recruited 40 South Asian and 40 Caucasian patients admitted for ACS. Data were collected by consulting patients' medical records. We used Chi-square test and Student's t-test to analyse qualitative and quantitative variables, respectively. South Asian patients, compared to Caucasians, showed higher mean values of the parameters analysed: remnant cholesterol (32.6 ± 17 vs 26.5 ± 9.6), Monocyte-to-HDL-cholesterol ratio (26.4 ± 48.7 vs 16.5 ± 8.3), Platelet-to-lymphocyte ratio (124.7 ± 130.7 vs 120.5 ± 58.8). Moreover, higher mean values of several lipoprotein ratios were also found in South Asian patients compared to the control group. However, statistical significance was not reached for any of these differences observed., Conclusions: The evaluation of the parameters analysed in this study might provide accurate information regarding the cardio-metabolic risk in South Asian patients. However, further studies with larger samples are needed to obtain more significant results., Competing Interests: Declaration of interests The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Simple Summary: Our study is the first one to investigate DNA methylation changes in white blood cells (WBCs) from easily accessible peripheral blood as malignant pleural mesothelioma (MPM) survival biomarker. The Cox proportional hazards regression model highlighted that the methylation status of the CpG dinucleotide cg03546163 is an independent marker of prognosis in MPM patients with a better performance than traditional inflammation-based scores such as lymphocyte-to-monocyte ratio (LMR). Biological validation and replication showed that epigenetic changes at the FKBP5 gene were robustly associated with overall survival (OS) in MPM cases. The identification of simple and valuable prognostic markers for MPM will enable clinicians to select patients who are most likely to benefit from aggressive therapies and avoid subjecting non-responder patients to ineffective treatment. Malignant pleural mesothelioma (MPM) is an aggressive tumor with median survival of 12 months and limited effective treatments. The scope of this study was to study the relationship between blood DNA methylation (DNAm) and overall survival (OS) aiming at a noninvasive prognostic test. We investigated a cohort of 159 incident asbestos exposed MPM cases enrolled in an Italian area with high incidence of mesothelioma. Considering 12 months as a cut-off for OS, epigenome-wide association study (EWAS) revealed statistically significant (p value = 7.7 × 10−9) OS-related differential methylation of a single-CpG (cg03546163), located in the 5′UTR region of the FKBP5 gene. This is an independent marker of prognosis in MPM patients with a better performance than traditional inflammation-based scores such as lymphocyte-to-monocyte ratio (LMR). Cases with DNAm < 0.45 at the cg03546163 had significantly poor survival compared with those showing DNAm ≥ 0.45 (mean: 243 versus 534 days; p value< 0.001). Epigenetic changes at the FKBP5 gene were robustly associated with OS in MPM cases. Our results showed that blood DNA methylation levels could be promising and dynamic prognostic biomarkers in MPM.

Background: Checkpoint inhibitors in melanoma can lead to self-immune side-effects such as vitiligo-like depigmentation (VLD). Beyond the reported association with favorable prognosis, there are limited data regarding VLD patient features and their echo on the therapeutic outcomes., Methods: To assess the association between VLD and a series of clinical and biological features as well as therapeutic outcomes, we built an observational cohort study by recruiting patients who developed VLD during checkpoint inhibitors., Results: A total of 148 patients from 15 centers (101 men, median age 66 years, BRAF mutated 23%, M1c 42%, Eastern Cooperative Oncology Group (ECOG) status 0/1 99%, normal lactate dehydrogenase 74%) were enrolled. VLD was induced by ipilimumab, programmed cell death-1 (PD-1) inhibitors, and their combination in 32%, 56%, and 12%, respectively. The median onset was 26 weeks and it was associated with other skin and nonskin toxicities in 27% and 28%, respectively. After 3 years of VLD onset, 52% (95% confidence interval 39% to 63%) were progression free and 82% (95% confidence interval 70% to 89%) were still alive. The overall response rate was 73% with 26% complete response. Univariable analysis indicated that BRAF V600 mutation was associated with a better overall survival (P = 0.028), while in multivariable analysis a longer progression-free survival was associated with BRAF V600 (P = 0.093), female sex (P = 0.008), and M stage other than 1a (P = 0.024). When VLD occurred, there was a significant decrease of white blood cell (WBC) count (P = 0.05) and derived WBC-to-lymphocytes ratio (dWLR; P = 0.003). A lower monocyte count (P = 0.02) and dWLR (P = 0.01) were also reported in responder patients., Conclusions: Among VLD population, some features might help to identify patients with an effective response to immunotherapy, allowing clinicians to make more appropriate choices in terms of therapeutic options and duration., Competing Interests: Disclosure The authors have declared no conflicts of interest., (Copyright © 2021 The Author(s).

Since the most frequent symptoms of novel coronavirus 2019 disease (COVID-19) are common in influenza A/B (FLU), predictive models to distinguish between COVID-19 and FLU using standardized non-specific laboratory indicators are needed. The aim of our study was to evaluate whether a recently dynamic nomogram, established in the Chinese population and based on age, lymphocyte percentage and monocyte absolute count, might apply to a different context. We collected data from 299 patients (243 with COVID-19 and 56 with FLU) at Policlinico Umberto I, Sapienza University of Rome. The nomogram included age, lymphocyte percentage and monocyte absolute count to differentiate COVID-19 from FLU. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated for all associations. Multivariate logistic regression models were used to adjust for potential confounding. A p-value of less than 0.05 was considered statistically significant. Patients with COVID-19 had higher age, lymphocyte percentage and monocyte absolute count than patients with FLU. Although univariate analysis confirmed that age, lymphocyte percentage and monocyte absolute count were associated with COVID-19, only at multivariate analysis was monocyte count statistically significant as a predictive factor of COVID-19. Using receiver operating characteristic (ROC) curves, we found that a monocyte count >0.35x1000/mL showed an AUC of 0.680 (sensitivity 0.992, specificity 0.368). A dynamic nomogram including age, lymphocyte percentage and monocyte absolute count cannot be applied to our context, probably due to differences in demographic characteristics between Italian and Chinese populations. However, our data showed that monocyte absolute count is highly predictive of COVID-19, suggesting its potential role above all in settings where prompt PCR nasopharyngeal testing is lacking.

Infection-triggered perturbation of the immune system could induce psychopathology, and psychiatric sequelae were observed after previous coronavirus outbreaks. The spreading of the Severe Acute Respiratory Syndrome Coronavirus (COVID-19) pandemic could be associated with psychiatric implications. We investigated the psychopathological impact of COVID-19 in survivors, also considering the effect of clinical and inflammatory predictors. We screened for psychiatric symptoms 402 adults surviving COVID-19 (265 male, mean age 58), at one month follow-up after hospital treatment. A clinical interview and a battery of self-report questionnaires were used to investigate post-traumatic stress disorder (PTSD), depression, anxiety, insomnia, and obsessive-compulsive (OC) symptomatology. We collected sociodemographic information, clinical data, baseline inflammatory markers and follow-up oxygen saturation levels. A significant proportion of patients self-rated in the psychopathological range: 28% for PTSD, 31% for depression, 42% for anxiety, 20% for OC symptoms, and 40% for insomnia. Overall, 56% scored in the pathological range in at least one clinical dimension. Despite significantly lower levels of baseline inflammatory markers, females suffered more for both anxiety and depression. Patients with a positive previous psychiatric diagnosis showed increased scores on most psychopathological measures, with similar baseline inflammation. Baseline systemic immune-inflammation index (SII), which reflects the immune response and systemic inflammation based on peripheral lymphocyte, neutrophil, and platelet counts, positively associated with scores of depression and anxiety at follow-up. PTSD, major depression, and anxiety, are all high-burden non-communicable conditions associated with years of life lived with disability. Considering the alarming impact of COVID-19 infection on mental health, the current insights on inflammation in psychiatry, and the present observation of worse inflammation leading to worse depression, we recommend to assess psychopathology of COVID-19 survivors and to deepen research on inflammatory biomarkers, in order to diagnose and treat emergent psychiatric conditions., (Copyright © 2020 Elsevier Inc.

The article examines the platelet recovery of patients with immune thrombocytopenia (ITP) after an eradication of Helicobacter pylori (H pylori). It states that Japan and Italy have higher response rate to H pylori eradication therapy than in the U.S. suggesting that it is influenced by ethnicity and genetic and environmental factors. It mentions on monocytes from H pylori-infected IPT patients that demonstrate low levels of inhibitory Fcγ receptor IIB gene and platelet phagocytosis.

BACKGROUND. Tubulointerstitial damage in patients with IgA nephropathy is associated with increased urinary levels of monocyte chemotactic peptide 1 (MCP1; CCL2) and reduced urinary levels of epidermal growth factor (EGF). OBJECTIVE. To determine whether the ratio of EGF to MCP1 in the urine predicts progression of IgA nephropathy. DESIGN AND INTERVENTION. Consecutive patients who had undergone renal biopsy at the Renal Unit of the University of Bari, Italy and who were diagnosed with IgA nephropathy between January 1995 and December 2000 were recruited for this prospective cohort study. Secondary IgA deposition and use of corticosteroids or immunosuppressants were exclusion criteria. Levels of EGF and MCP1 were determined by enzyme-linked immunosorbent assay in morning urine samples obtained at the time of biopsy. Follow-up visits took place every 3-6 months until December 2005. OUTCOME MEASURE. The end point was a composite of doubling of baseline serum creatinine level and development of end-stage renal disease (i.e. need for dialysis or transplantation). RESULTS. The cohort comprised 132 patients, of whom 91 (69%) were male and 41 (31%) were female. The mean age at biopsy was 31.6+11.4 years, and follow-up continued for a median of 54 months (range 35-84 months). The majority of participants (74%) received angiotensin-converting-enzyme inhibitors or angiotensin receptor blockers during followup. When the cohort was divided into tertiles according to EGF:MCP1 ratio, the lowest tertile had a higher prevalence of macrohematuria, hypertension, and severe nephropathy, higher mean levels of serum creatinine and proteinuria, and lower mean estimated creatinine clearance at baseline, than the highest tertile (P=0.03, P<0.0001, P<0.0001, P<0.0001, P=0.003 and P<0.0001, respectively). The rate of renal survival was greater in the highest tertile than in the middle or lowest tertiles (100% vs 94% vs 73% at 4 years and 100% vs 94% vs 36% at 7 years). In multivariate Cox regression analysis, the urinary EGF:MCP1 ratio was significantly associated with the composite end point after adjustment for factors including age proteinuria and histologic grade (P= 0.002). The area under a receiver operating characteristic (ROC) curve for prediction of the composite end point was 0.91 (95% CI 0.85-0.96) for urinary EGF:MCP1 ratio, 0.83 (95% CI 0.76-0.89) for urinary EGF level and 0.57 (95% CI 0.49-0.66) for urinary MCP1 level, indicating that urinary EGF:MCP1 ratio predicted renal outcome better than either EGF level or MCP1 level alone (P=0.01 and P<0.001, respectively). Urinary EGF:MCP1 ratio was also a better outcome predictor than estimated creatinine clearance, histologic grade and proteinuria in the ROC analysis (P=0.002, P=0.005 and P=0.004, respectively). At a cutoff of 23.2, urinary EGF:MCP1 ratio had a sensitivity and specificity of 88.9% and 86.4%, respectively, for prediction of the composite end point. CONCLUSION. Urinary EGF:MCP1 ratio seems to reliably predict renal outcome in IgA nephropathy and could identify patients who require more-intensive follow-up and treatment. [ABSTRACT FROM AUTHOR]

Objective: To verify whether absolute monocyte count (AMC) and lymphocyte- monocyte ratio (LMR) at diagnosis are valid prognostic parameters in classical Hodgkin lymphoma (cHL)., Patients and Methods: Data were collected from 1450 patients with cHL treated in Israel and Italy from January 1, 1988, through December 31, 2007., Results: The median age of the patients was 33 years (range, 17-72 years), and 70% (1017) of the patients had nodular sclerosis (NS); the median follow-up duration was 87 months. The best cutoff value for AMC was 750 cells/mm(3), and the best ratio for LMR was 2.1. The adverse prognostic impact of an AMC of more than 750 cells/mm(3) was confirmed for the entire cohort, and its clinical significance was particularly evident in patients with NS histology. The progression-free survival (PFS) at 10 years for an AMC of more than 750 cells/mm(3) was 65% (56%-72%), and the PFS at 10 years for an AMC of 750 cells/mm(3) or less was 81% (76%-84%; P<.001). The overall survival (OS) at 10 years for an AMC of more than 750 cells/mm(3) was 78% (70%-85%), and the OS at 10 years for an AMC of 750 cells/mm(3) or less was 88% (84%-90%; P=.01). In multivariate analysis, both AMC and LMR maintained prognostic significance for PFS (hazard ratio [HR], 1.54, P=.006, and HR, 1.50, P=.006) after adjusting for the international prognostic score, whereas the impact on OS was confirmed (HR, 1.56; P=.04) only in patients with NS and an AMC of more than 750 cells/mm(3)., Conclusion: This study confirms that AMC has prognostic value in cHL that is particularly significant in patients with NS subtype histology. This finding links the known impact of macrophages and monocytes in Hodgkin lymphoma with routine clinical practice., (Copyright © 2015 Mayo Foundation for Medical Education and Research.

An increased number of circulating monocytes at presentation has recently been associated with shorter survival in Hodgkin lymphoma, follicular lymphoma and diffuse large B cell lymphoma. This study aimed to assess the prognostic impact of the absolute monocyte count (AMC) at diagnosis in mantle cell lymphoma (MCL). AMC at diagnosis was available in 97 MCL cases recorded in the databases of the Oncology Institute of Southern Switzerland in Bellinzona (Switzerland) and the Division of Haematology of the Amedeo Avogadro University of Eastern Piedmont in Novara (Italy). With a median follow up of 7 years, the 5-year overall survival was 29% for patients with AMC >0·50 × 10(9) /l and 62% for patients with AMC ≤0·50 × 10(9) /l (P = 0·008). Elevated AMC and beta-2 microglobulin at diagnosis remained independent outcome predictors at multivariate analysis, controlling for the MCL International Prognostic Index (MIPI), and have been used to build a simple prognostic scoring system. In this relatively small and heterogeneous series an increased AMC identified poor-risk patients. Our results suggest that AMC together with the beta-2 microglobulin level might provide an inexpensive way to stratify MCL patient risk as a complement to the MIPI, which was confirmed to be a very powerful prognostic tool., (© 2013 John Wiley & Sons Ltd.)

Leukocytes are thought to play an important role in the pathogenesis of inflammatory bowel diseases; granulocyte-monocyte adsorptive (GMA) apheresis, an extracorporeal technique aimed at removing activated circulating leukocytes from the blood, may represent a safe and effective therapeutic tool in these patients. The Italian Registry of Therapeutic Apheresis performed an observational, multicentric study involving 24 Gastroenterology Units. In this study, laboratory data and clinical outcomes of 230 patients (148 males, mean age 43.5 years) affected with ulcerative colitis (UC, n = 194) or Crohn's disease (CD, n = 36) who underwent one or more cycles of GMA were analyzed. Each cycle consisted of five GMA treatments. The patients were followed up for a mean of 8.7 (min. 3 to max. 12) months. At 3 months, positive outcome was achieved in 77.7% of UC patients (72.0% remission, 5.7% clinical response) and 61.3% of CD patients (54.8% remission, 6.5% clinical response). The cumulative proportion of positive outcome at 12 months was 87.1% for UC patients (83.7% remission, 3.4% clinical response) and 77.4% for CD patients (74.2% remission, 3.2% clinical response). No single clinical or laboratory parameter among those analyzed (age, sex, disease characteristics, history of smoking, medication history, baseline values of clinical activity index (CAI)/Crohn's disease activity index (CDAI), hemoglobin, white blood cells count, and erythrocyte sedimentation rate) was independently associated with clinical outcome. The procedure was well tolerated with no significant adverse effects registered., (Copyright © 2011 Wiley Periodicals, Inc.)

On the ground of a statistical elaboration which has been carried throughout the Province of Forlì examining healthy people in order to observe eventual alteration in leucocytes' formula according to age and sex, in this way after a classification into five ageclasses, between 20 and 70 years, 250 men and 250 women, we could affirm that leucocytes' formula changes remarkably considering age and sex. So why we cannot take into consideration just a unique leucocytes' formula but on the contrary it is necessary to relate the above said formula to the age and the sex of a subject.
