Inflammatory bowel diseases (IBD) represent important chronic conditions affecting the gastrointestinal tract in man. However, similar disorders are found in several animal species and the IBD affecting dogs are particularly important. These are encompassed by an umbrella of probably several different entities with common symptoms, some of which seem to share striking similarities with human conditions. This review will focus on the actual knowledge of IBD in dogs, and attempt to identify differences and similarities with human IBD conditions. © 2010 Baishideng. All rights reserved.

HIV-infected patients are at increased risk for developing HIV-related Hodgkin lymphoma (HIV-HL) despite the success of combination antiretroviral therapy (cART). To study the incidence of HIV-HL in HIV-patients with respect to the general population of Brescia, Italy, we conducted a single-center cohort study of HIV-patients followed from 1999 to 2009. The incidence of HIV-HL was compared to the incidence in the general population of Brescia using standardized incidence ratios (SIRs). Poisson analysis was used to study the association between covariates and HL. A total of 5085 HIV-patients were observed among 30,946 person-years; 30 patients developed HIV-HL. The incidence rate was 9.9 (95% confidence interval [CI], 6.7-14.1) per 10,000 person-years of follow-up. HL was substantially more frequent in HIV-patients than in the general population living in the same district area [standardized incidence rate, SIR=21.8 (95% CI, 15.33-31)]. The risk of HIV-HL tended to increase with lowering CD4+ cell counts at time of HL diagnosis [adjusted incidence relative risk (IRR) for CD4 cell count<50 cells/μL: 41.70, p<0.001]. HL risk had been elevated during the 6 months after combination antiretroviral therapy (cART) initiation (IRR: 26.65, p<0.001). Twenty-two HIV-HL cases were matched to 3280 controls. In the year preceding HIV-HL diagnosis the mean change in CD4+ cell counts between cases and controls was significantly different (-99 cells/μL for cases vs. +37 cells/μL for controls, p<0.0001). Compared with the general population, HIV-infected patients showed an increased risk for developing HL. The risk of HIV-HL increased significantly in the first months after cART initiation. © 2013, Mary Ann Liebert, Inc.

Following the international guidelines criteria an adequate "diagnostic conclusion" of inflammatory bowel disease (IBD) can be achieved only if clinical, endoscopic and laboratory findings, together with sample technical adequacy and unequivocal histomorphological signs of the disease are available. Thus, a conclusive diagnosis requires a complex combination of clinical, endoscopic and histological data. A considerable number of endoscopic biopsies obtained from IBD patients do not meet the above-mentioned requirements. The aim of the present proposal is to introduce a binary system of evaluation in the "diagnostic conclusion" of the histopathological report that will help to simplify the clinical decisions and consequent patient management. In patients with no history of disease, the pathologist should classify the biopsies in "Diagnostic", when the criteria established by the international guidelines are satisfied and "not diagnostic" when one or more of the above-mentioned criteria are not met. The term "not diagnostic" should replace "highly suggestive" and "probable". This new terminology could avoid ambiguous expressions that encourage the clinician to classify the patient as affected by IBD without fulfilling all of the requirements for an accurate diagnostic approach. © 2013 Baishideng.

Objective: celiac disease (CD) is an immune-mediated chronic inflammatory disease associated with HLA-DQ2 and DQ8 molecules. We evaluated the role of HLA in the CD diagnostic algorithm in order to contribute to the development of practical indications for the use of HLA typing. Material and methods: we selected 317 subjects typed for DR-DQ genes. CD was present in 123 patients, and 89 were included in the study; a control sample of 70 healthy individuals was recruited. Results: 64% of patients with CD carried DQ2 heterodimer (a5b2), 13.5% carried DQ8 heterodimer without DQ2, 21.4% only showed b2 chain and 1.1% were positive for DQ2 a5 chain. The only presence of a5 chain did not predispose to CD, while DQB1*02 allele resulted more frequent than in other reports, pointing out the intrinsic correlation between b2 chain and CD. In the case-control study we observed a progression of increased risk, ranging from 1:7 for HLA-DQ2 homozygous to 1:85 for DQ8 heterozygous subjects. Overall, 8, 6% of first degree family members were affected, exclusively in presence of HLA-DQ2, -DQ8 or DQB1*02, and CD was significantly more frequent among siblings than parents. Finally, considering the different patterns of clinical presentation among the HLA-DQ risk classes identified we found no relationship between CD clinical presentation and HLA-DQ risk categories. Conclusions: our results strengthen the evidence that HLA-DQ status strongly influences the development of CD and demonstrate that knowledge of a patient's HLA-DQ genotype allows to establish clinically relevant genetic risk profiles. © 2012 ARÁN EDICIONES, S.

Context: The efficacy and favorable safety profile of anti-tumor necrosis factor (TNF) agents in the treatment of psoriasis and psoriatic arthritis (PsA) are supported by several randomized controlled studies and meta-analyses. However, some concerns on the long-term safety of these drugs still exist, as these studies generally included small patient numbers and were performed in selected patient populations. Objective: This review presents and discusses current evidence on the safety of anti-TNFα agents in patients with psoriasis and PsA, with a focus on European registry studies and case reports of particular importance. Methods: Key studies on the safety of anti-TNFα agents in the treatment of adult patients with psoriasis or PsA were identified by a MEDLINE search (last updated 10 November 2011) based on several interrelated queries, with a focus on European registries. Other studies and case reports were included if deemed relevant. Studies concerning other conditions, such as rheumatoid arthritis (RA), were included as appropriate when data in psoriatic disease were unavailable or insufficient. Results: Available data on the safety of anti-TNFα agents such as etanercept in psoriasis and PsA appear reassuring, even if some concerns still exist. Most notably, data suggest a higher incidence of infection and lymphoma amongst patients treated with the anti-TNFα monoclonal antibodies infliximab and adalimumab compared with etanercept. Conclusion: The overall safety profile of monoclonal antibodies in patients with psoriasis, PsA and RA seems less favorable than that of etanercept, particularly in terms of risk of infection and hepatotoxicity. © 2012 Informa Healthcare USA, Inc.
