An increasing number of women have been diagnosed with spondyloarthritis (SpA) in recent decades. While a few studies have analyzed gender as a prognostic factor of the disease, no studies have addressed this matter with a large number of patients in South America, which is a peculiar region due to its genetic heterogeneity. The aim of the present study was to analyze the influence of gender on disease patterns in a large cohort of Brazilian patients with SpA. A prospective study was carried out involving 1,505 patients [1,090 males (72.4%) and 415 females (27.6%)] classified as SpA according to the European Spondyloarthropaties Study Group criteria who attended at 29 reference centers for rheumatology in Brazil. Clinical and demographic variables were recorded and the following disease indices were administered: Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Radiologic Index (BASRI), Maastricht Ankylosing Spondylitis Enthesitis Score (MASES), and Ankylosing Spondylitis Quality of Life (ASQoL). Ankylosing spondylitis (AS) was the most frequent disease in the group (65.4%), followed by psoriatic arthritis (18.4%), undifferentiated SpA (6.7%), reactive arthritis (3.3%), arthritis associated to inflammatory bowel disease (3.2%), and juvenile SpA (2.9%). The male-to-female ratio was 2.6:1 for the whole group and 3.6:1 for AS. The females were older (p<0.001) and reported shorter disease duration (p=0.002) than the male patients. The female gender was positively associated to peripheral SpA (p<0.001), upper limb arthritis (p<0.001), dactylitis (p=0.011), psoriasis (p<0.001), nail involvement (p<0.001), and family history of SpA (p=0.045) and negatively associated to pure axial involvement (p< 0.001), lumbar inflammatory pain (p=0.042), radiographic sacroiliitis (p<0.001), and positive HLA-B27 (p=0.001). The number of painful (p<0.001) and swollen (p=0.006) joints was significantly higher in the female gender, who also achieved higher BASDAI (p<0.001), BASFI (p=0.073, trend), MASES (p=0.019), ASQoL (p=0.014), and patient's global assessment (p=0.003) scores, whereas the use of nonsteroidal anti-inflammatory drugs (p<0.001) and biological agents (p=0.003) was less frequent in the female gender. Moreover, BASRI values were significantly lower in females (p<0.001). The female gender comprised one third of SpA patients in this large cohort and exhibited more significant peripheral involvement and less functional disability, despite higher values in disease indices.

Prevalence rates for axial involvement in psoriatic arthritis (PsA) vary from 40% to 74% depending upon criteria for diagnosis. In the absence of trial evidence to assess axial involvement in PsA. the GRAPPA croup, by consensus, has suggested that outcome measures and therapies for axial disease ill ankylosing spondylitis (AS) be used. This systematic review addresses the management of axial disease in PsA, and provides treatment recommendations based oil the AS literature.

Objectives. To evaluate lipid profile changes after anti-TNF therapy in patients with psoriatic arthritis (PsA). Methods. Fifteen PsA patients (eight polyarticular, four oligoarticular, two axial, and one mutilating) under infliximab were included. None had dyslipoproteinemia or previous statin use. Total cholesterol (TC) and its fractions, inflammatory markers, and prednisone use were evaluated. Results. The comparisons of lipid levels between baseline and after three months (3M) of anti-TNF therapy showed that there was a significant increase in mean triglycerides (117.8 +/- 49.7 versus 140.1 +/- 64.1 mg/dL, P = 0.028) and VLDL-c (23.6 +/- 10.5 versus 28.4 +/- 13.7 mg/dL, P = 0.019) levels. In contrast, there were no differences in the mean TC (P = 0.28), LDL-c (P = 0.42), and HDL-c (P = 0.26) levels. Analysis of the frequencies of each lipid alteration at baseline and at 3M were alike (P > 0.05). Positive correlations were found between VLDL-c and CRP (r = 0.647, P = 0.009) and between triglycerides and CRP (r = 0.604, P = 0.017) levels at 3M. ESR reduction was observed after 3M (P = 0.04). Mean prednisone dose remained stable at beginning and at 3M (P = 0.37). Conclusion. This study demonstrated that anti-TNF may increase TG and VLDL-c levels in PsA patients after three months.

The objective of this study was to evaluate the influence of anti-tumor necrosis factor (anti-TNF) in juvenile idiopathic arthritis (DA), ankylosing spondylitis (AS) or psoriatic arthritis (PsA). Sixty-two patients were investigated: 7 DA; 37 AS; and 18 PsA. Caucasian race accounted for 79% and 29% were female. Mean age was 40.4 +/- 12.6years. None of the patients had a history of diabetes, and none had used oral hypoglycemic agents or insulin. Treatment was with adalimumab, infliximab and etanercept. Glucose, inflammatory markers and prednisone dose were assessed at baseline, as well as after three and six months of treatment. The mean erythrocyte sedimentation rate was significantly lower at three months and six months than at baseline (13.7 +/- 18.0 and 18 +/- 22.5 vs. 27.9 +/- 23.4 mm; p = 0.001). At baseline, three months and six months, we found the following: mean C-reactive protein levels were comparable (22.1 +/- 22.7, 14.5 +/- 30.7 and 16.0 +/- 23.8 mg/L, respectively; p = 0.26); mean glucose levels remained unchanged (90.8 +/- 22.2 mg/dl, 89.5 +/- 14.6 mg/dl and 89.8 +/- 13.6 mg/dl, respectively; p = 0.91); and mean prednisone doses were low and stable (3.9 +/- 4.9 mg/day, 3.7 +/- 4.8 mg/day and 2.6 +/- 4.0 mg/day, respectively; p = 0.23). During the first six months of treatment, anti-TNF therapy does not seem to influence glucose metabolism in JIA, AS or PsA. (C) 2010 The International Association for Biologicals.

This prospective study analyzed the frequency of HLA-B27 and its alleles in 102 Brazilian patients with psoriatic arthritis (PsA). The association of the HLA-B27 alleles with these variants was compared to a control healthy HLA-B27 positive group of 111 individuals. There was a predominance of male gender (59.8%), Caucasian race (89.2%), and negative HLA-B27 (79.4%) patients. Asymmetric oligoarthritis (62.7%) was the most frequently observed clinical PsA subgroup, followed by spondylitis (16.7%), and polyarthritis (15.7%). Male gender and the spondylitis subgroup were statistically associated to the positive HLA-B27, and the oligoarthritis subgroup was associated to the negative HLA-B27. Among the 21 HLA-B27-positive PsA patients, there was a significant prevalence of the HLA-B*2705 allele (90.5%), similar to that observed in the control group (80.2%); HLA-B*2703 and HLA-B*2707 were statistically associated to the control group.

RESUMO:A artrite psoriática (AP) é uma doença inflamatória crónica caracterizada por várias manifestações nas articulações, nas enteses e na pele. A formação de novo osso após inflamação nas enteses é um dos aspetos mais intrigantes desta doença. Os mecanismos celulares e moleculares deste processo ainda não são completamente conhecidos. Este estudo tem como objetivo compreender melhor os mecanismos subjacentes à formação e reabsorção óssea, bem como o efeito de anti-inflamatórios não esteroides (AINEs) nestes processos. Para atingir este objetivo foram quantificados biomarcadores do metabolismo ósseo e citocinas inflamatórias em doentes AP, antes e após terapêutica com AINEs. Os biomarcadores selecionados foram marcadores de remodelação óssea como CTX-I e P1NP, fatores de diferenciação e ativação de osteoclastos como o RANKL e a OPG, inibidores da via de sinalização Wnt, nomeadamente o DKK-1 e a SOST e ainda citocinas pro-inflamatórias como a IL-22 e a IL-23 e a prostaglandina PGE2. Neste contexto foram também estabelecidas culturas celulares de monócitos, isoladas de doentes AP e de controlos saudáveis. Os monócitos foram cultivados in vitro em condições não estimuladas e estimuladas e realizados dois ensaios funcionais: coloração com TRAP e ensaio de reabsorção. Foi observada uma diminuição nos níveis séricos de CTX-I e OPG em doentes AP em relação aos controlos. De igual forma os níveis séricos de SOST encontram-se significativamente mais baixos, em comparação com os controlos saudáveis. Estes valores de SOST são semelhantes aos dos doentes com espondilite anquilosante (EA), documentados anteriormente. Os ensaios com osteoclastos confirmaram a necessidade da presença de RANKL para estimulação da osteoclastogénese e que o celecoxib parece ter um papel inibitório neste processo. Os resultados obtidos sugerem que a população de doentes com AP analisados têm baixos níveis de reabsorção óssea e alguma atividade na formação óssea. --------------------------- ABSTRACT: Psoriatic arthritis (PsA) is a chronic inflammatory disease characterized by several manifestations involving the joints, enthesis and the skin. New bone formation after inflammation at enthesis site has been one of the most intriguing aspects of the disease. Cellular and molecular mechanisms in this process are still not completely understood. This study aims to understand better the mechanisms underlying bone formation and resorption and the effect of non-steroid anti-inflammatory drugs (NSAIDs) in these processes. To access that, biomarkers of bone metabolism and inflammatory cytokines were measured in PsA patients’ serum before and after NSAID therapy. These selected biomarkers were bone turnover markers such as CTX-I and P1NP, osteoclast differentiation and activation factors RANKL and OPG, Wnt pathway inhibitors DKK-1 and SOST and pro-inflammatory cytokines IL-22, IL-23 and prostaglandin PGE2. In this context monocyte cell culture was also established after PBMC isolation from PsA patients and healthy controls. Monocytes were cultured in vitro under unstimulated and stimulated conditions and two functional assays were performed: TRAP staining and resorption pit assay. It was demonstrated that CTX-I and OPG serum levels in PsA patients were lower than controls. SOST levels were extremely decreased in comparison with controls, resembling the ankylosing spondylitis patients results already documented. Osteoclast assays confirmed the need of RANKL in stimulating osteoclastogenesis and that celecoxib seems to have an inhibitor role in this process. The results obtained suggest that PsA patient population analyzed in this study have low bone resorption levels and some bone formation activity.

BACKGROUND: Psoriatic arthritis (PsA) substantially impacts the management of psoriatic disease. OBJECTIVE: This study aimed to generate an interdisciplinary national consensus on recommendations of how PsA should be managed. METHODS: Based on a systematic literature search, an interdisciplinary expert group identified important domains and went through 3 rounds of a Delphi exercise, followed by a nominal group discussion to generate specific recommendations. RESULTS: A strong consensus was reached on numerous central messages regarding the impact of PsA, screening procedures, organization of the interaction between dermatologists and rheumatologists, and treatment goals. CONCLUSION: These recommendations can serve as a template for similar initiatives in other countries. At the same time, they highlight the need to take into account the impact of the respective national health care system. © 2015 S. Karger AG, Basel.

The development of psoriatic plaques is T cell dependent. Recently, Th17 CD4 T cells have been proposed to be the main effector cells. However, development of psoriasis is critically dependent on accumulation of epidermal T cells, among the majority express CD8. Here we show that numbers of epidermal CD8 T cells correlated with development of psoriasis in human biopsies, and that blockade of CD8 T cells by depleting antibodies inhibited development of psoriasis in the AGR xenotransplantation mouse model. In human dermis, both CD4 and CD8 T cell numbers correlated significantly with epidermal pathology, indicating a role for dermal CD4 T cells in orchestrating the development of psoriasiform changes induced by epidermis-infiltrating CD8 T cells.

Psoriatic arthritis is a chronic inflammatory disease. It affects up to 40% of patients suffe- ring from skin psoriasis. Joint involvement is relatively heterogeneous. Some clinical manifestations are similar to those of rheumatoid arthritis, others are close to spondylarthritis manifestations and are therefore considered as part of this entity. Treatment depends on initial presentation (peripheral or axial) but often begins with non-steroidal anti-inflammatory drugs and methotrexate, followed by anti-TNFalpha if needed. New therapeutic op- tions are available or under evaluation, parti- cularly targeting cytokines involved in psoriatic arthritis (IL-12/IL-23 and IL-17).

I am continually surprised by the acts of estrangement in which my body engages. All bodies do this to some extent – lungs breathe, hearts beat and so on, but with psoriasis, which my article is concerned with, these processes are highly visible. As a condition of the skin, it is a pathology which is enacted both within and without, visible to the social world as well emerging from some little understood inflammatory source within the body. This article will undertake a phenomenological exploration of my own skin and how my experience of my body is affected by its lack of compliance with medicine, cosmetics etc. By some unknown causation it flakes, breaks, itches constantly drawing attention to bodily limits and the limits of medical knowledge. I want to think through the meanings we ascribe to such inflammatory conditions in Western society, how my skin materialises at the nexus of industrialisation, medicine, class and capital. This investigation will emerge at the limit point, the thin skin between the subjective and objective, observing and theorising my skin in ways which dissolve disciplinary boundaries, to comprehend the cultural, biological and environmental forces that work upon my body, estranging it from me.

Background: Paradoxical cases of psoriatic lesions induced or exacerbated by anti-tumor necrosis factor (TNF)-α therapy have been reported more frequently in recent years, but data related to inflammatory bowel disease (IBD) are rare. A systematic literature review was performed to provide information about this adverse effect in patients with IBD who receive anti-TNF therapy. Methods: Published studies were identified by a search of Medline, Embase, Cochrane, SciELO, and LILACS databases. Results: A total of 47 studies (222 patients) fulfilled the inclusion criteria and were selected for analysis. Clinical and therapeutic aspects varied considerably among these reports. Of the 222 patients, 78.38% were diagnosed with Crohn's disease, and 48.20% were female. The mean patient age was 26.50. years, and 70.72% of patients had no history of psoriasis. Patients developed psoriasiform lesions (55.86%) more often than other types of psoriatic lesions, and infliximab was the anti-TNF-α therapy that caused the cutaneous reaction in most patients (69.37%). Complete remission of cutaneous lesions was observed in 63.96% of the cases. Conclusions: We found that psoriatic lesions occurred predominantly in adult patients with Crohn's disease who received infliximab and had no previous history of psoriasis. Most patients can be managed conservatively without discontinuing anti-TNF-α therapy. © 2012 European Crohn's and Colitis Organisation.

Studies have shown a relationship between vitamin D and psoriasis. We compared serum levels of vitamin D of 20 psoriasis patients and 20 controls. The median vitamin D level was 22.80 +/- 4.60 ng/ml; the median in the cases was 23.55 +/- 7.6 ng/ml, and in controls 22.35 +/- 3.10 ng/ml (p = 0.73). Only 2 cases and 4 controls had sufficient levels of vitamin D, although without statistical significance between the groups (p = 0.608). Levels were lower in women with psoriasis compared with those in male patients (20.85 +/- 6.70 x 25.35 +/- 2.90 ng/ml, p = 0.03), a finding that was not observed among controls.
