    Gouty arthritis is one of the most common rheumatic diseases. The clinical burden of gouty arthritis has historically been well recognized; however, gout is often misdiagnosed and mismanaged. The prevalence of gout is rising and is likely attributed to several factors including increased incidence of comorbidities, lifestyle factors, and increased use of causative medications. With the increasing prevalence, there have been several innovations and evidence-based updates related to the diagnosis and management of gout. Acute gouty arthritis should be treated with nonsteroidal antiinflammatory drugs (NSAIDs), colchicine, or corticosteroids, or a combination of two agents. Xanthine oxidase inhibitor therapy remains the consensus first-line treatment option for the prevention of recurrent gout. Add-on therapies that reduce serum urate concentration include traditional uricosuric agents and a novel uric acid reabsorption inhibitor. Prophylaxis of acute gout with NSAIDs, colchicine, or corticosteroids is universally recommended when initiating any urate-lowering therapy in order to prevent acute gouty arthritis for a period of at least 6 months. In this review, we discuss the epidemiology and risk factors for gouty arthritis and evaluate diagnostic strategies and therapeutic regimens for the management of gout, including a new drug approval.

    Indium-111-labeled leukocyte scintigraphy was performed on a 66-yr-old male with polyarticular acute gouty arthritis. Images revealed intense labeled leukocyte accumulation in a pattern indistinguishable from septic arthritis, in both knees and ankles, and the metatarsophalangeal joint of both great toes, all of which were involved in the acute gouty attack. Joint aspirate as well as blood cultures were reported as no growth; the patient was treated with intravenous colchicine and ACTH for 10 days with dramatic improvement noted. Labeled leukocyte imaging, repeated 12 days after the initial study, revealed near total resolution of joint abnormalities, concordant with the patient's clinical improvement. This case demonstrates that while acute gouty arthritis is a potential pitfall in labeled leukocyte imaging, in the presence of known gout, it may provide a simple, objective, noninvasive method of evaluating patient response to therapy.

    Flurbiprofen has been compared with phenylbutazone in a double-blind study involving 33 patients with acute gout. Patients received either flurbiprofen 400 mg daily for 48 h followed by 200 mg daily, or phenylbutazone 800 mg daily for 48 h followed by 400 mg daily. The drugs were of comparable efficacy, while side-effects were uncommon and relatively mild. Flurbiprofen appears to be a satisfactory alternative to phenylbutazone in the management of acute gouty arthritis. PMID:3907678

    Objective To assess the safety and efficacy of etoricoxib, a selective cyclo-oxygenase-2 inhibitor, in comparison with indometacin in the treatment of acute gouty arthritis. Design Randomised, double blind, active comparator controlled trial. Setting 43 outpatient study centres in 11 countries. Participants 142 men and eight women (75 patients per treatment group) aged 18 years or over presenting with clinically diagnosed acute gout within 48 hours of onset. Interventions Etoricoxib 120 mg administered orally once daily versus indometacin 50 mg administered orally three times daily, both for 8 days Main outcome measures Patients' assessment of pain in the study joint over days 2 to 5 (primary end point); investigators' and patients' global assessments of response to treatment and tenderness of the study joint (key secondary end points). Results Etoricoxib showed efficacy comparable to indometacin. Patients' assessment of pain in the study joint (0-4 point Likert scale, “no pain” to “extreme pain”) over days 2 to 5 showed a least squares mean change from baseline of −1.72 (95% confidence interval −1.90 to −1.55) for etoricoxib and −1.83 (−2.01 to −1.65) for indometacin. The difference between treatment groups met prespecified comparability criteria. All other efficacy end points, including those reflecting reduction in inflammation and analgesia, provided corroborative evidence of comparable efficacy. Significant pain relief was evident at the first measurement, 4 hours after the first dose of treatment. Prespecified safety analyses revealed that drug related adverse experiences occurred significantly less frequently with etoricoxib (22.7%) than with indometacin (46.7%) (P=0.003), although overall adverse experience rates were similar between the two treatment groups. Conclusion Etoricoxib 120 mg once daily provides rapid and effective treatment for acute gouty arthritis comparable to indometacin 50 mg three times daily. Etoricoxib was generally

    Septic arthritis and gout are major diseases that should be suspected in patients with acute monoarthritis. These two diseases are clinically similar and often indistinguishable without the help of synovial fluid analysis. Recently, a novel diagnostic rule for gout without synovial fluid analysis was developed and showed relevant performances. This study aimed to determine whether this diagnostic rule could perform well in distinguishing gout from septic arthritis. The diagnostic rule comprises 7 clinical and laboratory variables, each of which is given a specified score. The probability of gout is classified into 3 groups according to the sum of the scores: high (≥ 8), intermediate (> 4 to < 8) and low probability (≤ 4). In this retrospective study, we applied this diagnostic rule to 136 patients who presented as acute monoarthritis and were subsequently diagnosed as acute gout (n = 82) and septic arthritis (n = 54) based on synovial fluid analysis. The mean sum of scores of acute gout patients was significantly higher than that of those with septic arthritis (8.6 ± 0.2 vs. 3.6 ± 0.32, P < 0.001). Patients with acute gout had significantly more 'high', and less 'low' probabilities compared to those with septic arthritis (Eta[η]: 0.776). The prevalence of acute gouty arthritis, as confirmed by the presence of monosodium crystal, was 95.5% (61/64), 57.5% (19/33), and 5.1% (2/39) in high, intermediate and low probability group, respectively. The recently introduced diagnostic rule properly discriminates acute gout from septic arthritis. It may help physicians diagnose gout in cases difficult to be differentiated from septic arthritis.

    The aims of the current study are to describe gadolinium-enhanced MRI features of an acute flare of established gouty arthritis in different joints and to examine a possible association between serum uric acid and MRI signs indicative of ongoing inflammation and/or structural joint damage as well as association with disease characteristics and laboratory findings. Twenty-seven male patients with established chronic gout agreed to participate, mean age 47.6 years, and mean disease duration in months 43.2 (±31.8). For all patients, detailed demographic, disease characteristics, and laboratory findings were obtained and correlated with MRI findings. In 27 patients with established gout, a total of 50 MRI studies were performed of the following joints: feet joints (n = 23), ankles (n = 18), knees (n = 5), and hand and wrist joints (n = 4). MRI revealed capsular thickening in 19 patients, bone marrow edema (BME) in 15, soft tissue edema (STE) in 20, joint effusion in 21, bone erosions in 17, cartilaginous erosions in 4, and tenosynovitis in 9 cases. In 17 cases, tophaceous lesions were found. Post contrast MRI showed synovial thickening in seven cases. Positive correlations were observed between serum uric acid levels and the following MRI findings: capsular thickening (r = 0.552, p = 0.003), BME (r = 0.668, p ≤ 0.0001), STE (r = 0.559, p = 0.002), and tenosynovitis (r = 0.513, p = 0.006). Using MRI in chronic gout, important features can be detected like BME, minute cartilaginous erosions, and hypertrophic synovial inflammation in post contrast MR images. Serum uric acid (SUA) was positively correlated with capsular thickening, BME, STE, and tenosynovitis.

    Hyperuricemia is a common metabolic abnormality in subjects with renal transplantation: in fact in transplanted adults receiving immunosuppressive and diuretic drugs the frequency of hyperuricemia varied from 30 to 84% according to treatment. Conversely, the gout is an uncommon eventuality, representing less than 10%; predisposing factors are impaired renal function and older age. In the younger patients with renal transplantation hyperuricemia is also frequent, but the gout doesn't considered a possible complication in paediatric age. We reported our observation of 5 patients (3 males and 2 females), 13-18 years old who developed gout 2-84 months after renal transplantation. All the patients were receiving cyclosporine, 4 even with prednisone and azathioprine. Two patients were treated with furosemide because hypertension. The average of uric acid serum levels in the post transplantation follow-up was 7 +/- 2 mg/dl; at the moment of gout attack the uric acid serum levels raised to 12 +/- 1 mg/dl. The arthritis diagnosis were made by clinical, laboratory and instrumental data (Rx and US). In the most severe cases, uricasi therapy resolved clinical picture. The analysis of immunosuppressive and diuretic treatment, renal function and dietary uses induces us to think that the gout episode may be the result of many concomitant factors, in adolescents with renal transplant.

    Paracoccidioidomycosis is an endemic South American systemic mycosis caused by the dimorphic fungus Paracoccidioides brasiliensis (P. brasiliensis). The main clinical form of disease is pulmonary, but all organs may be involved. We report a case of overinfection by P. brasiliensis in chronic gouty arthritis affecting the proximal phalanx of the right hallux. The patient required proximal amputation and long-term antifungal therapy. PMID:23251162

    Purpose Patients with gout are similar to those with bacterial infection in terms of the nature of inflammation. Herein we compared the differences in procalcitonin (PCT) levels between these two inflammatory conditions and evaluated the ability of serum PCT to function as a clinical marker for differential diagnosis between acute gouty attack and bacterial infection. Materials and Methods Serum samples were obtained from 67 patients with acute gouty arthritis and 90 age-matched patients with bacterial infection. Serum PCT levels were measured with an enzyme-linked fluorescent assay. Results Serum PCT levels in patients with acute gouty arthritis were significantly lower than those in patients with bacterial infection (0.096±0.105 ng/mL vs. 4.94±13.763 ng/mL, p=0.001). However, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels showed no significant differences between the two groups. To assess the ability of PCT to discriminate between acute gouty arthritis and bacterial infection, the areas under the curves (AUCs) of serum PCT, uric acid, and CRP were 0.857 [95% confidence interval (CI), 0.798–0.917, p<0.001], 0.808 (95% CI, 0.738–0.878, p<0.001), and 0.638 (95% CI, 0.544–0.731, p=0.005), respectively. There were no significant differences in ESR and white blood cell counts between these two conditions. With a cut-off value of 0.095 ng/mL, the sums of sensitivity and specificity of PCT were the highest (81.0% and 80.6%, respectively). Conclusion Serum PCT levels were significantly lower in patients with acute gouty attack than in patients with bacterial infection. Thus, serum PCT can be used as a useful serologic marker to differentiate between acute gouty arthritis and bacterial infections. PMID:27401644

    A 15-year-old girl, a known case of Bartter's syndrome (BS) for 7 years, developed severe pain in her right knee and right and left ankle. Her older sister had BS and developed end-stage renal disease (ESRD) at the age of 14 years. Her serum uric acid was 12.6 mg/dL, 6 months ago, and 15.4 mg/dL in her recent lab data. Hyperuricemia and gouty arthritis are commonly seen in adults with BS, but to our knowledge there is no report of gouty arthritis in pediatric literature.

    The anti-inflammatory effect of morin, a dietary bioflavanol was explored on monosodium urate (MSU) crystal-induced inflammation in rats, an experimental model for acute gouty arthritis. Morin treatment (30mg/kg b.wt) significantly attenuated the ankle swelling and the levels of lipid peroxidation, nitric oxide, serum pro-inflammatory cytokines (tumor necrosis factor (TNF) -α, interleukin (IL)-1β, and IL-6), monocyte chemoattractant protein (MCP)-1, vascular endothelial growth factor (VEGF), prostaglandin E2 (PGE2), and articular elastase along with an increased anti-oxidant status (catalase (CAT) and superoxide dismutase (SOD)) in the joint homogenate of MSU crystal-induced rats. Histological assessment revealed that morin limited the diffusion of joint space, synovial hyperplasia, and inflammatory cell infiltrations. The mRNA expression of NLRP3 (nucleotide oligomerization domain (NOD)-like receptor family, pyrin domain containing 3) inflammasome, caspase-1, pro-inflammatory cytokines, MCP-1, inflammatory enzymes (inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2)), and nuclear factor-kappa B (NF-κB) p65 was found downregulated and HPRT (hypo-xanthine phospho-ribosyl transferase) mRNA expression was upregulated in morin treated MSU crystal-induced rats. In addition, morin treatment reduced the protein expression of NF-κB p65, p-NF-κB p65, iNOS, COX-2, and TNF-α. The results clearly demonstrated that morin exert a potent anti-inflammatory effect on MSU crystal-induced inflammation in rats.

    The traditional Chinese antirheumatic herb Danggui-Nian-Tong-Tang (DGNTT) was studied comparatively with indomethacin and allopurinol to evaluate its anti-inflammatory and antihyperuricemic effects in patients with gout. Results in this study did not show any significant improvement in reducing the total number of painful and swollen joints, articular index and pain score (P > 0.05) by treatment with DGNTT. Unlike allopurinol, DGNTT did not lower the high serum level of uric acid. In vitro study in rats showed that DGNTT significantly inhibits the activity of beta-glucuronidase (P < 0.05) and lysozyme release (P < 0.01) from neutrophils. In conclusion, despite the effect of inhibition on enzyme release from neutrophils, DGNTT is not effective in treating acute arthritis or hyperuricemia.

    Gouty arthritis is the most common type of inflammatory and immune disease, and the prevalence and incidence of gout increases annually. Genetic variations in the DNA methyltransferases (DNMTs) gene have not, to the best of our knowledge, been reported to influence gene expression and to participate in the pathogenesis of gout. The aim of the present study was to investigate whether the DNMT1, DNMT3A and DNMT3B polymorphisms contribute to gout susceptibility. These polymorphisms were screened for in 336 gout patients and 306 healthy control subjects (from a South China population) for association with gout. The distribution frequencies of DNMT1 rs2228611 AA genotype (P=0.007) and A allele (P=0.002; odds ratio=1.508, 95% confidence interval=1.158–1.964) were found to be significantly increased in the gout patients when compared with those in the healthy control subjects. The rs1550117 in DNMT3A and rs2424913 in DNMT3B exhibited no significant associations with gout susceptibility between the patients and control subjects. These results demonstrated that the DNMT1 rs2228611 polymorphism may be involved in the pathogenesis of gout, while DNMT3A rs1550117 and DNMT3B rs2424913 did not show any obvious significance in the current study; thus, may not be used as risk factors to predict the susceptibility to gout. However, further studies are required to investigate the functions and regulatory mechanism of the polymorphisms of DNMTs in gout. PMID:27699015

    Background The toll-like receptor (TLR)4-interleukin1β (IL1β) signaling pathway is involved in the monosodium urate (MSU)-mediated inflammation. The aim of this present study was to determine whether the TLR4 gene rs2149356 SNP is associated with gouty arthritis (GA) susceptibility and whether rs2149356 SNP impacts the TLR4-IL1β signaling pathway molecules expression. Methods and Findings The rs2149356 SNP was detected in 459 GA patients and 669 control subjects (containing 459 healthy and 210 hyperuricemic subjects). Peripheral blood mononuclear cells (PBMCs) TLR4 mRNA and serum IL1β were measured in different genotype carriers, and correlations between TLR4 gene SNP and TLR4 mRNA, IL1β were investigated. The frequencies of the genotype and allele were significantly different between the GA and control groups (P<0.01, respectively). The TT genotype was associated with a significantly increased risk of GA (OR = 1.88); this finding was not influenced by making adjustments for the components of possible confounders (adjusted OR = 1.96). TLR4 mRNA and IL1β were significantly increased in the TT genotype from acute GA patients (P<0.05, respectively), and lipids were significantly different among three genotypes in the GA patients (P<0.05, respectively). Conclusions The TLR4 gene rs2149356 SNP might be associated with GA susceptibility, and might participate in regulating immune, inflammation and lipid metabolism. Further studies are required to confirm these findings. PMID:23738004

    Based on traditional Chinese medicinal theories on gouty arthritis, Zisheng Shenqi decoction (ZSD), a novel Chinese medicinal formula, was developed due to its multiple functions, including reinforcing renal function, promoting blood circulation and relieving pain. In the present study, the effect of ZSD on monosodium urate (MSU) crystal-induced gouty arthritis in rats was investigated and the underlying mechanisms were examined. The data from these investigations showed that the injection of MSU crystals into the ankle joint cavity caused significant elevations in ankle swelling and inflammatory cell infiltration into the synovium, whereas these abnormal changes were markedly suppressed by oral administration of ZSD (40 mg/kg) for 7 days. Mechanically, ZSD treatment prevented MSU crystal-induced inflammatory responses, as evidenced by downregulation in the expression levels of NACHT domain, leucine-rich repeat and pyrin domain containing protein (NALP) 1 and NALP6 inflammasomes, decreased serum levels of tumor necrosis factor-α and interleukin-1β, and inhibited activation of nuclear factor-κB. In addition, ZSD administration markedly enhanced the anti-oxidant status in MSU crystal-induced rats by the increase in the activities of superoxide dismutase and glutathione peroxidase, and the levels of reduced glutathione. These results indicated that ZSD effectively prevented MSU crystal-induced gouty arthritis via modulating multiple anti-oxidative and anti-inflammatory pathways, suggesting a promising herbal formula for the prevention and treatment of gouty arthritis.

    RuPeng15 Powder (RPP15) is a herbal multicompound remedy that originates from traditional Tibetan medicine and possesses antigout, anti-inflammatory, and antihyperuricemic properties based on the traditional conceptions. The present study was undertaken to evaluate the therapeutic effect of PRP15 in rat gouty arthritis induced by monosodium urate (MSU) crystals. In the present study, we found that treatment with RPP15 (0.4, 0.8, and 1.2 g/kg) in rats with gouty arthritis induced by MSU crystals significantly attenuated the knee swelling. Histomorphometric and immunohistochemistry analyses revealed that MSU-induced inflammatory cell infiltration and the elevated expressions of nuclear transcription factor-κB p65 (NF-κB p65) in synovial tissues were significantly inhibited, and enzyme-linked immunosorbent assay (ELISA) result showed that MSU-induced high levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and interleukin-8 (IL-8) in synovial fluid were reduced by treatment with RPP15 (0.4, 0.8, and 1.2 g/kg). We conclude that RPP15 may be a promising candidate for the development of a new treatment for gout and its activity of antigout may be partially related to inhibiting TNF-α, IL-1β, IL-8, and NF-κB p65 expression in the synovial tissues.

    Whether the levels of procalcitonin (PCT) in the serum and synovial fluid are effective indicators for distinguishing septic arthritis (SA) from non-infectious arthritis remains controversial. The present study aimed to evaluate whether PCT levels in fresh serum or fresh joint fluid may be used in the differential diagnosis of SA from rheumatoid arthritis (RA), osteoarthritis (OA) and gouty arthritis (GA). From January 2012 to June 2013, 23 patients with knee SA, 21 patients with RA, 40 patients with OA and 11 patients with GA were enrolled in the current study. The levels of PCT were measured within 24 h after specimen collection at room temperature. An enzyme-linked fluorescence assay (ELFA) was used to detect the levels of PCT in the serum and synovial fluid. The correlations between the levels of PCT in the serum and synovial fluid and the arthritic patient groups were determined by the Nemenyi test. Areas under the receiver operating characteristic (ROC) curve were calculated to evaluate the accuracy of the correlations. The levels of PCT in the serum and joint fluid of the patients in the SA group were higher compared with those of the other groups (P<0.01) and there were no significant differences among the RA, OA and GA groups in these levels. A PCT level of <0.5 μg/l in the serum and synovial fluid had high specificity in the differential diagnosis of SA from RA, OA and GA. Synovial fluid PCT revealed significantly greater sensitivity than serum PCT. The accuracy of the differential diagnosis of SA by the serum levels of PCT was significantly lower than that by the synovial fluid levels of PCT. The levels of PCT in the serum and synovial fluid may be used as alternative laboratory indicators to distinguish between SA and the non-infectious types of arthritis; however, the PCT levels in fresh synovial fluid are more sensitive and accurate indicators than PCT levels in fresh serum.

    Gouty arthritis is a rheumatic disease that is characterized by the deposition of monosodium urate (MSU) in synovial joints cause by the increased serum hyperuricemia. This study used a three-dimensional (3D) flowing microfluidic chip to screen the effective candidate against MSU-stimulated human umbilical vein endothelial cell (HUVEC) damage, and found kinsenoside (Kin) to be the leading active component of Anoectochilus roxburghi, one of the Chinese medicinal plant widely used in the treatment of gouty arthritis clinically. Cell viability and apoptosis of HUVECs were evaluated, indicating that direct Kin stimulation and conditioned medium (CM) from Kin-treated macrophages both negatively modulated with MSU crystals. Additionally, Kin was capable of attenuating MSU-induced activation of nuclear factor-κB/mitogen-activated protein kinase (NF-κB/MAPK) signaling, targeting IκB kinase-α (IKKα) and IKKβ kinases of macrophages and influencing the expressions of NF-κB downstream cytokines and subsequent HUVEC bioactivity. Inflammasome NLR pyrin domain-containing 3 (NALP3) and toll-like receptor 2 (TLR2) were also inhibited after Kin treatment. Also, Kin downregulated CD14-mediated MSU crystals uptake in macrophages. In vivo study with MSU-injected ankle joints further revealed the significant suppression of inflammatory infiltration and endothelia impairment coupled with alleviation of ankle swelling and nociceptive response via Kin treatments. Taken together, these data implicated that Kin was the most effective candidate from Anoectochilus roxburghi to treat gouty arthritis clinically. PMID:27584788

    The present study was undertaken to evaluate the therapeutic effects of Huzhang-Guizhi herb pair (HG), firstly included in Hu-Zhang Power documented in Taiping Shenghui Fang, on monosodium urate (MSU) crystals-induced gouty arthritis in rats. We found that pretreatment with HG in rats with gouty arthritis could significantly attenuate the ankle joint swelling, and this beneficial antigout effect might be mediated, at least in part, by inhibiting tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) production in synovial fluid as well as nuclear transcription factor-κB p65 (NF-κB p65) protein expression in synovial tissue. Moreover, metabonomic analysis demonstrated that 5 and 6 potential biomarkers associated with gouty arthritis in plasma and urine, respectively, which were mainly involved in energy metabolism, amino acid metabolism, and gut microbe metabolism, were identified. HG could reverse the pathological process of MSU-induced gouty arthritis through regulating the disturbed metabolic pathways. These results provided important mechanistic insights into the protective effects of HG against MSU-induced gouty arthritis in rats. PMID:26989428

    Gouty knee arthritis refers to a form of inflammatory diseases caused by deposits of needle-like crystals of uric acid in knee joint. The aim of this study was to assess the efficacy and safety of arthroscopic debridement in combination with oral medication versus oral medication alone for the treatment of gouty knee arthritis. A total of 60 patients with gouty knee arthritis were randomized to receive either arthroscopic surgery in combination with oral medication or oral medication alone. Efficacy was assessed with the angle of motion, functions, and visual analog scale (VAS). These indices were measured prior to treatment and at 2, 4, 12, 24, and 48 weeks posttreatment. Surgery- and medication-related complications were observed. Significant differences in flexion and extension of the knee joint, lymphoma scores, and VAS were detected between the two groups at 2, 4, and 12 weeks posttreatment (P < 0.05) but not at weeks 24 and 48 posttreatment (P > 0.05) . Significant differences in these indices were detected at different time points in each group (P < 0.05), except between weeks 24 and 48 (P > 0.05). Arthroscopic surgery in combination with oral medication is superior to single oral medication in the flexion and extension of the knee joint, lymphoma scores, and pain relief (VAS) before 24 weeks, although no statistical differences were detected in the efficacy after 24 weeks, and in medication-related safety between the two groups. Although arthroscopic debridement cannot replace systemic uric acid-lowering treatments such as medication and dietary control, it is still an effective approach. PMID:26730077

    Acute arthritis can first present as a symptom of dangerous and rapidly progressing disease. It is quite easy to differentiate between arthritis and periarthritis. More problematical is correct early differential diagnosis of the acute arthritis. Determining whether one, several or many joints are affected can narrow the diagnostic possibilities. Arthrocentesis and synovial fluid testing provide much information and should be done at initial evaluation if possible. The presence or absence of fever, rash, family history of joint disease and exposure to infective organisms can further direct diagnostic studies and treatment. In general, to avoid masking clues, drug therapy should be delayed for mild symptoms until diagnosis is complete. This article is designed mostly for primary care physicians, residents and includes author's original data and review of recommended reading. PMID:12794379

    Objective: Dioscorea nipponica Makino is one of the most common used traditional Chinese drugs which are used to treat gouty arthritis (GA). Nuclear factor-κB (NF-κB) pathway plays an important role during this process. In the present study, we investigated the effects of total saponins from D. nipponica Makino (TDN) on NF-κB pathway in interleukin-1β (IL-1β) induced fibroblast-like synoviocytes (FLS). Materials and Methods: FLS were divided into three groups: Normal group, model group, which was given 10 μg/L IL-1β to induce the proliferation, and TDN group (10 μg/L IL-1β +100 μg/L TDN). 1 h, 24 h, 48 h, and 72 h after treating, immune fluorescence method was used to detect the cell location of NF-κB p65. Electrophoretic mobility shift assay was used to detect the activation of NF-κB p65. Western blot method was used to detect the protein expressions of NF-κB p65, IκBα, and p-IκBα. Results: TDN could inhibit the activation and transfer of NF-κB p65. As time went on, the expression of NF-κB p65 in the cytoplasm was decreased while it was increased in the nucleus. The expression of p-IκBα was increased, whereas the expression of IκBα was not changed. TDN could regulate these abnormal expressions. Conclusion: TDN may treat GA by regulating NF-κB signal pathway. SUMMARY TDN could inhibit the transfer of NF-κB p65.TDN could inhibit the activation of NF-κB p65.TDN could inhibit the expression of p-IκBa.

    Aim: This study was conducted to evaluate the in vitro anti-inflammatory activities and total phenolic content (TPC) of methanolic extracts of infloresence axes, endosperms, leaves, and pericarps of Barringtonia racemosa L. Methods: The anti-inflammatory study was conducted by assessing the potential through xanthine oxidase (XO) and albumin denaturation inhibition assays. Meanwhile, the TPC in the extracts were assessed by Folin-Ciocalteu assay. Results: In the XO inhibition assay, the infloresence axes extract was found to exert the highest inhibition capacity at 0.1% (w/v) with 59.54 ± 0.001% inhibition followed by leaves (58.82 ± 0.001%), pericarps (57.99 ± 0.003%), and endosperms (57.20 ± 0.003%) extracts. Similarly in the albumin denaturation inhibition assay, the infloresence axes extract had shown the greatest inhibition capacity with 70.58 ± 0.004% inhibition followed by endosperms (66.80 ± 0.024%), leaves (65.29 ± 0.006%), and pericarps extracts (43.33 ± 0.002%). Meanwhile, for TPC analysis, leaves extract was found to have the highest phenolic content (53.94 ± 0.000 mg gallic acid equivalent [GAE]/g DW) followed by infloresence axes (31.54 ± 0.001 mg GAE/g DW), endosperms (22.63 ± 0.001 mg GAE/g DW), and the least was found in pericarps (15.54 ± 0.001 mg GAE/g DW). Conclusion: The results indeed verified the in vitro anti-inflammatory activities of B. racemosa and supported its potential to be used in alleviating gouty arthritis and XO-related diseases.

    Hypoxanthine-guanine phosphoribosyltransferase (HGPRT) (EC 2.4.2.8) reversibly catalyzes the transfer of the 5-phophoribosyl group from 5-phosphoribosyl-alpha-1-pyrophosphate (PRPP) to hypoxanthine or guanine to form inosine monophosphate (IMP) or guanosine monophosphate (GMP) in the purine salvage pathway. To investigate the catalytic mechanism of this enzyme in the intracellular pathogen Legionella pneumophila, we determined the crystal structures of the L. pneumophila HGPRT (LpHGPRT) both in its apo-form and in complex with GMP. The structures reveal that LpHGPRT comprises a core domain and a hood domain which are packed together to create a cavity for GMP-binding and the enzymatic catalysis. The binding of GMP induces conformational changes of the stable loop II. This new binding site is closely related to the Gout arthritis-linked human HGPRT mutation site (Ser103Arg). Finally, these structures of LpHGPRT provide insights into the catalytic mechanism of HGPRT.

    Background/Aims: Gout is a common inf lammatory arthritis triggered by the crystallization of uric acid in the joints. Serum uric acid levels are highly heritable, suggesting a strong genetic component. Independent studies to confirm the genetic associations with gout in various ethnic populations are warranted. We investigated the association of polymorphisms in the ABCG2 and SLC2A9 genes with gout in Korean patients and healthy individuals. Methods: We consecutively enrolled 109 patients with gout and 102 healthy controls. The diagnosis of gout was based on the preliminary criteria of the America College of Rheumatology. Genomic DNA was extracted from whole blood samples. We identified single nucleotide polymorphism (SNP) changes in the ABCG2 and SLC2A9 genes using a direct sequencing technique. rs2231142 in ABCG2 and rs6449213 and rs16890979 in SLC2A9 and nearby regions were amplified by polymerase chain reaction. Results: Patients with gout had significantly higher A/A genotype (29.3% vs. 4.9%, respectively) and A allele (52.8% vs. 26.5%, respectively) frequencies of rs2231142 in ABCG2 than did controls (χ2 = 29.42, p < 0.001; odds ratio, 3.32; 95% confidence interval, 2.11 to 5.20). We found novel polymorphisms (c.881A>G and c.1002+78G>A) in the SLC2A9 gene. The univariate logistic regression analysis revealed that the c.881A>G and c.1002+78G>A SNPs were significantly higher in patients than in controls. Conclusions: We demonstrated a significant association between rs2231142 in the ABCG2 gene and gout and identified novel SNPs, c.881A>G and c.1002+78G>A, in the SLC2A9 gene that may be associated with gout in a Korean population.

    This study aimed at determining the sensitivity and specificity of Gram staining of synovial fluid as a diagnostic tool in acute septic arthritis. A retrospective study was made of 22 patients who had arthroscopic lavage following a provisional diagnosis of acute septic arthritis of the knee joint. Gram stains and cultures of the knee aspirates were compared with the clinical and laboratory parameters, to evaluate their usefulness in diagnosing acute arthritis. All patients who had septic arthritis had pain, swelling and limitation of movement. CRP was elevated in 90% of patients. The incidence of elevated white blood cell count was higher in the group of patients with a positive Gram stain study (60%) as compared to patients with a negative Gram stain study (33%). Gram staining sensitivity was 45%. Its specificity was however 100%. Gram staining is an unreliable tool in early decision making in patients requiring urgent surgical drainage and washout.

    Psoriatic arthritis is a seronegative arthropathy occurring in the presence of psoriasis. In majority of cases, typical psoriatic skin lesions precede joint disease, making diagnosis of psoriatic arthritis without typical skin lesions, a diagnostic challenge. Nail lesions are commonly seen in patients affected by this condition, making it a useful clue in the diagnosis of psoriatic arthritis. This is a case of a 58-year-old Filipino woman presenting with sudden acute urinary retention and weakness of both lower extremities accompanied with active polyarthritis. Onycholytic nail changes initially thought to be a fungal nail infection led to the diagnosis of psoriatic arthritis involving the spine. The patient was eventually treated with methotrexate and non-steroidal anti-inflammatory drugs leading to full resolution of symptoms. The patient is currently ambulatory and on regular follow-up. This case report highlights the importance of clinical and physical findings particularly the nails that would lead to a diagnosis of psoriatic arthritis. PMID:24789155

    A 70-year-old woman with a history of medial femoro-tibial compartment of knee osteoarthritis was admitted for acute arthritis six days after a second intra-articular injection of Hyaluronic acid. The joint fluid was inflammatory, with no crystals, and laboratory tests showed marked inflammation leading to antibiotic treatment for suspected septic arthritis. The persistent symptoms and negative results of joint fluid and blood cultures led to discontinuation of the antibiotic therapy after 10 days. Anti-inflammatory with rehabilitation therapy of the knee relieved the symptoms, and the patient was discharged home 3 weeks after her admission. Aseptic arthritis induced by repeated Hyaluronic acid injection is the most likely diagnosis. Physicians should be conscious of this extremely severe complication.

    1984-04-01

    In order to study the haemodynamic changes of the juvenile knee in acute arthritis, an experimental model was developed in puppies by unilateral intra-articular injections of Carragheenin solution into the knee. Tissue blood flow was studied by the tracer microsphere technique in eight dogs and simultaneous intra-articular and intraosseous pressure recordings were performed in seven other dogs. The intra-articular pressure was elevated in all arthritic knees. Hyperaemia was found in the knee-joint capsule and distal femoral metaphysis, whereas juxta-articular epiphyseal blood flow rates were not significantly changed. A decrease of femoral muscle blood flow was encountered. Intraosseous pressure recordings during venous tamponade of the knee-joint capsules suggested a qualitative change of bone vasculature in acute arthritis. The juxta-articular bone blood flow in arthritis appears to be influenced by synovial hyperaemia, synovial effusion pressure, an "inflammatory resistance factor" and the anatomical relationship of the epiphyseal vessels to the knee-joint capsule.

    Acute leukemia in children presents with various clinical manifestations that mimic orthopaedic conditions. The association of septic arthritis of the elbow with acute leukemia is very rare, and the correct diagnosis of acute leukemia is often established only after treatment of the septic arthritis. In this article, we present a three-year-old child patient with elbow septic arthritis related to acute leukemia, diagnosed promptly by bone marrow aspiration on the same day as emergency surgical debridement of the septic elbow joint due to the maintenance of a high index of suspicion, and treated with chemotherapy as soon as possible. The emergency physician and orthopaedist must recognize unusual patterns of presentation like this. Since delay in initiating treatment of septic arthritis may result in growth disturbance, elbow septic arthritis associated with pediatric acute leukemia must be treated promptly and appropriately. Early diagnosis is a good prognostic feature of childhood acute leukemia.

    Arthritis could be a presenting feature of acute lymphoblastic leukaemia (ALL) and could be wrongly diagnosed as juvenile rheumatoid arthritis (JRA). Clinical and laboratory parameters might differentiate ALL and JRA in children who present with arthritis. Out of a total of 250 children of ALL, 10 were referred to the department of child health and paediatric haemato-oncology of Christian Medical College, Vellore during 1990-2002. They were compared with 10 age-matched children who had systematic onset of JRA. The age groups in ALL and JRA were 6.05 +/- 2.45 years and 5.47 +/- 4.4 years respectively. Severe pain as evidenced by inability to walk was found in children but one child with JRA was unable to walk (p < 0.05). Lymphocytosis was noticed in 7 children (70%) with ALL whereas none had in JRA group. ESR was elevated in all cases in both the groups. One case in each group had antinuclear antibody positivity. It can be concluded that ALL can masquerade as systematic onset of JRA. So paediatricians should be careful enough while diagnosing the disease process.

    Renal tubular acidosis (RTA) is a disorder of renal acidification characterized by inability to acidify urine to pH < 5.5 despite the presence of severe systemic metabolic acidosis and hypokalemia. Hypokalemia leads to acute-onset paralysis and may be a presenting manifestation of RTA. Its association with various autoimmune disease has been reported previously in published reports, but has not been much emphasized. We, hereby, report a case of RTA that presented during the flare of rheumatoid arthritis (RA). A 42-year-old female, a known case of RA for 5 years, presented with persistent joint pain for 1 week and acute-onset quadriparesis for 3 days. Primary investigations revealed hypokalemia with metabolic acidosis. She was managed conservatively with potassium supplements and bicarbonate supplements along with steroids and disease-modifying anti-rheumatic drugs. Such a presentation of renal tubular acidosis in a patient during the flare of rheumatoid arthritis is distinctly rare and previously unreported in published studies. PMID:26142942

    Acute osteomyelitis and septic arthritis are two infections whose frequencies are increasing in pediatric patients. Acute osteomyelitis and septic arthritis need to be carefully assessed, diagnosed, and treated to avoid devastating sequelae. Traditionally, the treatment of acute osteoarticular infection in pediatrics was based on prolonged intravenous anti-infective therapy. However, results from clinical trials have suggested that in uncomplicated cases, a short course of a few days of parenteral antibiotics followed by oral therapy is safe and effective. The aim of this review is to provide clinicians an update on recent controversies and advances regarding the management of acute osteomyelitis and septic arthritis in children. In recent years, the emergence of bacterial species resistant to commonly used antibiotics that are particularly aggressive highlights the necessity for further research to optimize treatment approaches and to develop new molecules able to fight the war against acute osteoarticular infection in pediatric patients.

    Acute septic arthritis of childhood is a potentially devastating disease that causes permanent disability and can result in death. Traditional treatment consists of a prolonged course of intravenous antibiotics combined with aggressive surgery. However, this approach is challenged by trials showing satisfactory outcomes with shorter treatment and less invasive surgery. Diagnostic arthrocentesis alone and an antibiotic for a fortnight, including initial intravenous administration for 2-4 days, suffice in most non-neonatal cases. A good penetrating agent, such as clindamycin or a first-generation cephalosporin, exceptionally high doses, and administration four times a day are probably key factors. If the symptoms and signs subside within a few days, and the serum C-reactive protein level drops below 20 mg/l, the antibiotic can usually be safely discontinued. Methicillin-resistant Staphylococcus aureus is a concern, but fortunately, most strains have retained susceptibility to clindamycin. The above guidance is not applicable to neonates and immunocompromised patients who may require a different approach.

    Objective To evaluate the antiarthritic activity of Ajuga bracteosa using albino rats. Methods The antiarthritic activity of 70% ethanolic extract of Ajuga bracteosa (EEAB) was evaluated against turpentine oil- and formaldehyde- induced acute non immunological and complete freund's adjuvant (CFA)-induced chronic immunological arthritis in albino rats. Results EEAB showed a significant (P<0.05) and dose dependent inhibitory effect against acute and chronic models of arthritis. EEAB exhibited better antiarthritic activity than the standard aspirin. Conclusions EEAB exhibits a significant and promising antiarthritic activity against acute and chronic arthritis and supports the traditional use of Ajuga bracteosa for rheumatism and other inflammatory diseases.

    We report two cases of acute hip arthritis where arthrocentesis was able to be performed rapidly, at the bedside by the emergency physician using ultrasound guidance, expediting diagnosis and patient care. In the first case, the patient, who was 23 weeks pregnant, was diagnosed with septic hip arthritis, taken for operative washout of the joint and did very well postoperatively with no pregnancy or other complications. In the second case, the patient was determined to have a noninfectious etiology and also did well. Skilled ultrasound guidance allows hip arthrocentesis to be performed by the treating clinician, decreasing the time to diagnosis and definitive care.

    Rheumatoid arthritis (RA) is a common systemic disease that manifests as inflammatory arthritis of multiple joints and produces a wide variety of intrathoracic lesions, including pleural diseases, diffuse interstitial pneumonia, rheumatoid nodules, and airway disease. Patients treated for RA can have associated lung disease that commonly manifests as diffuse interstitial pneumonia, drug-induced lung injury, and infection. The purpose of this pictorial review is to illustrate the radiographic and clinical features of lung complications of acute or subacute onset in patients treated for RA and to show the computed tomography features of these complications.

    A combination of surgical and medical treatment is normally required for patients with septic arthritis. Antibiotics selected for use on these patients are normally based on tissue culture results. However, in sub-acute and chronic septic arthritis cases, the results of the culture are usually negative as a result of prior treatment. The present study will investigate the incidence of culture-negative septic arthritis and the outcomes based on the use of first-line drug antibiotics for the treatment of sub-acute and chronic septic arthritis. For the present study, the authors retrospectively reviewed medical records of surgically treated septic arthritis cases over the past 10 years at Siriraj Hospital. The patient culture results, the antibiotics used, and the results of treatment were all recorded and analyzed. One hundredfifty-three septic arthritis patients were reviewed. Sixty-two patients were classified as having been diagnosed with either sub-acute or chronic septic arthritis. Thirty-six of 62 patients (58.1%) had a negative culture result. In the culture-positive patients, 42.3% had Streptococcus, 26.9% had Staphylococcus aureus, 11.5% had other gram positive bacteria, 15.4% had gram-negative bacteria, and 3.8% had tuberculus infection. In the culture-negative sub-acute and chronic group (36 of 62), 23 patients received Cefazolin, nine patients received Cloxacillin, and four patients received Clindamycin. Successful results were 69.9%, 66.7% and 75%, respectively. The present study reflects that the incidence ofculture-negative, sub-acute and chronic septic arthritis is approximately 58.1%. The first-line class of antibiotics remains the appropriate antibiotic choice for these patients because they are still effective for treatment of septic arthritis in up to 70% of all cases.

    Gout provides some unique challenges in classification and measurement of outcomes. Our aim was to evaluate criteria for classification and to develop and validate optimal instruments to measure outcomes for acute and chronic gout. A planning committee and interested attendees met to propose classification criteria and domains for outcomes. Seven of the current American Rheumatism Association preliminary criteria for classification were proposed as the best current criteria for acute gouty arthritis, pending further studies. The presence of gout is best established by crystal identification, although this technique has limitations. Five domains for acute gout outcomes and 9 for chronic gout were identified along with proposed instruments for testing and validation. The unique problems of gout evaluation can and will be addressed.

    Metabolic alterations are associated with arthritis apart from obesity. However, it is still unclear which is the underlying process behind these metabolic changes. Here, we investigate the role of tumor necrosis factor (TNF) in this process in an acute model of antigen-induced arthritis (AIA). Immunized male BALB/c mice received an intra-articular injection of PBS (control) or methylated bovine serum albumin (mBSA) into their knees, and were also pre-treated with different drugs: Etanercept, an anti-TNF drug, DF2156A, a CXCR1/2 receptor antagonist, or a monoclonal antibody RB6-8C5 to deplete neutrophils. Local challenge with mBSA evoked an acute neutrophil influx into the knee joint, and enhanced the joint nociception, along with a transient systemic metabolic alteration (higher levels of glucose and lipids, and altered adipocytokines). Pre-treatment with the conventional biological Etanercept, an inhibitor of TNF action, ameliorated the nociception and the acute joint inflammation dominated by neutrophils, and markedly improved many of the altered systemic metabolites (glucose and lipids), adipocytokines and PTX3. However, the lessening of metabolic changes was not due to diminished accumulation of neutrophils in the joint by Etanercept. Reduction of neutrophil recruitment by pre-treating AIA mice with DF2156A, or even the depletion of these cells by using RB6-8C5 reduced all of the inflammatory parameters and hypernociception developed after AIA challenge, but could not prevent the metabolic changes. Therefore, the induction of joint inflammation provoked acute metabolic alterations which were involved with TNF. We suggest that the role of TNF in arthritis-associated metabolic changes is not due to local neutrophils, which are the major cells present in this model, but rather due to cytokines. PMID:26742100

    The use of immunobiological agents for the treatment of autoimmune diseases is increasing in medical practice. Anti-TNF therapies have been increasingly used in refractory autoimmune diseases, especially rheumatoid arthritis, with promising results. However, the use of such therapies has been associated with an increased risk of developing other autoimmune diseases. In addition, the use of anti-TNF agents can cause pulmonary complications, such as reactivation of mycobacterial and fungal infections, as well as sarcoidosis and other interstitial lung diseases (ILDs). There is evidence of an association between ILD and the use of anti-TNF agents, etanercept and infliximab in particular. Adalimumab is the newest drug in this class, and some authors have suggested that its use might induce or exacerbate preexisting ILDs. In this study, we report the first case of acute ILD secondary to the use of adalimumab in Brazil, in a patient with rheumatoid arthritis and without a history of ILD. PMID:24626274

    Currently, there are 5 existing classification criteria for gout: the Rome, New York, American Rheumatism Association (ARA), Mexico, and Netherlands criteria. This study was carried out to determine the performance of these classification criteria in Thai patients presenting with acute arthritis.All consecutive patients presenting with acute arthritis and being consulted at the Rheumatology Unit, Chiang Mai University Hospital from January 2013 to May 2015 were invited to join the study. Gout was defined by the presence of monosodium urate crystals in the synovial fluid or tissue examined by experienced rheumatologists. The 5 existing gout classification criteria were performed and evaluated in all of the patients, who were divided in subgroups of early disease (≤2 years), established disease (>2 years), and those without tophus.There were 136 gout and 97 nongout patients. Sensitivity and specificity across all criteria ranged from 75.7% to 97.1% and 68.0% to 84.5%, respectively. Overall, the Mexico criteria had the highest sensitivity (97.1%), and the ARA survey criteria the highest specificity (84.5%), whereas the Mexico criteria performed well in early disease with sensitivity and specificity of 97.1% and 81.7%, respectively. All 5 criteria showed high sensitivity (from 76.4% to 99.1%) but low specificity (from 30.8% to 65.4%) in established disease. In patients without tophus, the sensitivity and specificity ranged from 64.1% to 95.7% and 68.8% to 85.4%, respectively. The ARA survey criteria across all groups showed consistently high specificity for gout.The 5 existing classification criteria for gout had limited sensitivity and specificity in Thai patients presenting with acute arthritis. The ARA survey criteria are the most suitable for diagnosing gout in Thai people when crystal identification is not available.

    We present a case report of a four-year-old boy with torcicollis and trismus after acute otitis media. Grisel Syndrome diagnosis in association with temporo-mandibular reactive arthritis was admitted, leading to early conservative treatment. GS should be suspected in a child presenting with torticollis after an upper respiratory tract infection or an ENT surgical procedure. The association with temporo-mandibular reactive findings is somehow rarer but not impossible, due to the close vascular communication between retropharyngeal and pterigoid spaces.

    The study was conducted to determine whether patients with rheumatoid arthritis (RA) are at increased risk of acute pancreatitis compared with those without RA and to determine if the risk of acute pancreatitis varied by anti-RA drug use. We used the large population-based dataset from the National Health Insurance (NHI) program in Taiwan to conduct a retrospective cohort study. Patients newly diagnosed with RA between 2000 and 2011 were referred to as the RA group. The comparator non-RA group was matched with propensity score, using age and sex, in the same time period. We presented the incidence density by 100,000 person-years. The propensity score and all variables were analyzed in fully adjusted Cox proportional hazard regression. The cumulative incidence of acute pancreatitis was assessed by Kaplan-Meier analysis, with significance based on the log-rank test. From claims data of one million enrollees randomly sampled from the Taiwan NHI database, 29,755 adults with RA were identified and 119,020 non- RA persons were matched as a comparison group. The RA cohort had higher incidence density of acute pancreatitis (185.7 versus 119.0 per 100,000 person-years) than the non-RA cohort. The adjusted hazard ratio (HR) was 1.62 (95% CI [confidence interval] 1.43–1.83) for patients with RA to develop acute pancreatitis. Oral corticosteroid use decreased the risk of acute pancreatitis (adjusted HR 0.83, 95% CI 0.73–0.94) but without a dose-dependent effect. Current use of disease modifying anti-rheumatic drugs or tumor necrosis factor blockers did not decrease the risk of acute pancreatitis. In conclusion, patients with RA are at an elevated risk of acute pancreatitis. Use of oral corticosteroids may reduce the risk of acute pancreatitis. PMID:26262880

    Drug-induced pulmonary disease is an important consideration in the differential diagnosis of patients with rheumatoid arthritis (RA) who present with respiratory symptoms. We report a patient with RA who developed acute respiratory failure two weeks after the administration of abatacept. The clinical findings were consistent with drug-induced acute respiratory failure, most likely acute eosinophilic pneumonia. Pulse steroid was administered at 1000 mg/kg/day in the emergency department. Chest X-ray and arterial blood gas values revealed significant improvement on the second day of hospitalization. However, in the second week, the patient’s fever rose up to 40°C, procalcitonin level increased to 15 ng/mL (<0.5 ng/mL is normal), and the patient died because of sepsis in the fourth week. This is the second report of respiratory failure, after the abatacept administration in the literature. We have reported an acute respiratory failure that occurred after use of the biological agent abatacept. With the increasing use of novel immunomodulatory agents, it is important for clinicians and pathologists to add the possibility of a drug reaction to the traditional differentials of acute respiratory failures occurring in these settings.

    Acute lymphoblastic leukemia (ALL) often presents with osteoarthritic manifestations which may lead to misdiagnosis with juvenile rheumatoid arthritis (JRA). This study was designed to identify ALL patients with initial diagnosis of JRA, compare their clinicolaboratory characteristics and outcome with other ALL patients treated at our center. Case records of 762 patients with ALL were analyzed. Information regarding the clinical-demographic profile, therapy and outcome were recorded. Of the children, 49 (6.4%) had initial presentation mimicking JRA. Asymmetric oligoarthritis was the most common pattern of joint involvement. Majority presented with fever, pallor, arthritis, night pain, and bone pain. None of the routine prognostic factors including age, gender, lymphadenopathy, hepatosplenomegaly, total leukocytes count (TLC), and platelet count were significantly associated with relapse/death. The mean symptom-presentation interval (SPI), hemoglobin was significantly higher whilst the TLC was significantly lower in these patients compared to other ALL patients. The 5 year overall-survival was better than other patients with ALL (p = 0.06, by logrank test). Significantly longer SPI in these patients underscores the need for prompt and early investigations to rule out ALL in patients of JRA with atypical features and pointers of ALL. Children with ALL-mimicking JRA may belong to a subgroup of ALL with a better prognosis.

    Flexor tenosynovitis of the hand is often caused by trauma or infection. Gouty tenosynovitis is an uncommon presentation of the condition and is usually misdiagnosed as infection with the patient undergoing surgery. The coexistence of infection and gout causing flexor tenosynovitis has never been described before in the literature; we report the first ever case and emphasise the importance of its awareness for optimal treatment. A 54-year-old man was initially diagnosed and treated as having infective flexor tenosynovitis and, later, due to a lack of improvement in his symptoms, was discovered to also have gout. We review the literature and suggest management strategy for use in daily clinical practice, including an algorithm, for this presentation. PMID:27358092

    Acute-onset arthritis is a common clinical problem facing both the general clinician and the rheumatologist. A viral aetiology is though to be responsible for approximately 1% of all cases of acute arthritis with a wide range of causal agents recognised. The epidemiology of acute viral arthritis continues to evolve, with some aetiologies, such as rubella, becoming less common due to vaccination, while some vector-borne viruses have become more widespread. A travel history therefore forms an important part of the assessment of patients presenting with an acute arthritis. Worldwide, parvovirus B19, hepatitis B and C, HIV and the alphaviruses are among the most important causes of virally mediated arthritis. Targeted serological testing may be of value in establishing a diagnosis, and clinicians must also be aware that low-titre autoantibodies, such as rheumatoid factor and antinuclear antibody, can occur in the context of acute viral arthritis. A careful consideration of epidemiological, clinical and serological features is therefore required to guide clinicians in making diagnostic and treatment decisions. While most virally mediated arthritides are self-limiting some warrant the initiation of specific antiviral therapy. PMID:27037381

    Oligosaccharide structures are attached to nearly all membrane and serum proteins, and their composition changes significantly in many diseases. We have analysed glycosylation of IgG heavy chains in 34 patients with juvenile chronic arthritis and 13 control individuals. IgG was purified from 0.7 ml of serum, separated by electrophoresis and transferred on to polyvinylidene difluoride (PVDF) membrane. Ricinus communis agglutinin (RCA I) and Bandeirea simplicifolia (BSA II) and Ulex europaeus (UEA I) lectins were used to measure galactose, N-acetylglucosamine and fucose, respectively. While there was no significant difference in average levels of galactose and N-acetylglucosamine, patients with juvenile chronic arthritis had 2.4 times more fucose attached to IgG heavy chains than control individuals. A different picture emerged when patients were divided into those with acute disease and those in remission. Patients in whom juvenile chronic arthritis was currently active had significantly lower levels of galactose than those in remission, in whom galactose levels were comparable to the control group. Fucose levels in both groups of patients were significantly higher than in the control group. These results show that whereas de-galactosylation is a good test to detect and measure the activity of juvenile chronic arthritis, increased fucosylation is a much more reliable measure for diagnosis of the disease itself.

    Virgin olive oil is the primary source of fat in the Mediterranean diet, and its beneficial health effects have been related with oleic acid and phenolic compounds content. Hydroxytyrosol, a typical virgin olive oil phenolic compound, has beneficial antioxidant and anti-inflammatory properties as previously reported. The aim of this study was to evaluate the effect of hydroxytyrosol-supplemented refined olive oil at 0.5 and 5 mg/kg in a rodent model of rheumatoid arthritis. Rheumatoid arthritis was induced by intradermic administration, in male Wistar rats, of Freund's adjuvant with collagen type II on days 1 and 21. Hydroxytyrosol-supplemented refined olive oils were administrated by gavage from day 23 until day 35. The treatment at 5-mg/kg dose significantly decreased paw edema (P<.01), histological damage, cyclooxygenase-2 and inducible nitric oxide synthase expression, and markedly reduced the degree of bone resorption, soft tissue swelling and osteophyte formation, improving articular function in treated animals. Acute inflammation, induced by carrageenan, was also evaluated for hydroxytyrosol-supplemented refined olive oils at 0.5 and 5 mg/kg. Both doses significantly reduced paw edema (P<.001). Our results suggest that the supplementation of refined olive oil with hydroxytyrosol may be advantageous in rheumatoid arthritis with significant impact not only on chronic inflammation but also on acute inflammatory processes.

    Fibrosarcoma is a malignant mesenchymal tumor. To the author’s best knowledge, no previous case of fibrosarcoma arising from gouty tophi has been reported. Here we reported the first case of fibrosarcoma arising from gouty tophi. A case of 58-year-old man was presented with a mass with ulcer and infection in the second joint of left middle finger for 2 months, with long standing gouty tophi. The tumor was biopsied and the biopsy showed complete excision of the tumor. With the pathological and immunohistochemical features considered, the diagnosis of fibrosarcoma associated with gouty tophi was made. The clinical findings, pathological characteristics and treatment were described. PMID:26097616

    Septic arthritis of the acromioclavicular (AC) joint is a rare entity with symptoms that include erythema, swelling, and tenderness over the AC joint, fever, and limitation of shoulder motion with pain. In previous reports, Staphylococcus and Streptococcus species have been mentioned as common causative organisms. Haemophilus parainfluenzae is a normal inhabitant of the oral cavity, respiratory tract, gastrointestinal tract, and urogenital tract. However, it sometimes causes opportunistic infections leading to septic arthritis and osteomyelitis. AC joint infection associated with H.parainfluenzae is very rare, and only one case has been reported in the literature. Moreover, septic arthritis in immunocompetent patients is also very rare. Here, we report the case of a healthy patient with H. parainfluenzae-related septic arthritis of the AC joint.

    This is a Consensus Document of the Sociedad Española de Infectología Pediátrica, Sociedad Española de Reumatología Pediátrica and Sociedad Española de Ortopedia Pediátrica on the aetiology and diagnosis of uncomplicated acute osteomyelitis and septic arthritis. A review is presented of the aetiopathogenesis and pathophysiology of acute osteoarticular infection defined as a process with less than 14 days of symptomatology, uncomplicated, and community-acquired. The diagnostic approach to these conditions is summarised based on the best available scientific knowledge. Based on this evidence, a number of recommendations for clinical practice are provided.

  11. Pathogenesis of acute arthritis due to viable Chlamydia trachomatis (mouse pneumonitis agent) in C57Bl/6 mice.

    The purpose of this investigation was to determine the natural history and pathogenesis of the acute arthritis induced by inoculation of a viable Chlamydia trachomatis biovar (mouse pneumonitis agent or MoPn) in C57Bl/6 mice. Immunologically naive (previously unsensitized) mice as well as mice immunized against Chlamydia (MoPn) by vaginal infection were employed. Both intravenous and intraarticular inoculations were employed. No arthritis developed after intravenous injections of MoPn although statistically significant antibody titers and splenic enlargement ensued. Intra-articular inoculation into knee joints produced a definite arthritis of 7 to 10 days duration marked by granulocyte and mononuclear cell infiltration of the joint and vacuolated synovial macrophages that stained heavily for chlamydial antigen by immunoperoxidase technique. Statistically significant increases in articular acute and chronic inflammation (P less than 0.02 were observed in previously sensitized, but not unsensitized, female mice at 2 but not 7 days after intra-articular chlamydial challenge. Chlamydiae were isolated from injected joints up to day 5, but not at day 10, after challenge. Chlamydial antigen disappeared rapidly from knee joints between day 10 and 15 after challenge. Electron micrographs demonstrated vacuolated synovial cells of the macrophage type, many of which contained degenerating chlamydial elementary bodies. Reticulate and intermediate bodies also were seen but were far less frequent than degenerating elementary bodies. Unaltered elementary bodies were difficult to identify beyond day 2 after articular inoculation. Thus, it appears likely that intra-articular chlamydial survival is shorter than the duration of the arthropathy. This may have important implications in attempts to identify chlamydiae in human joints in Reiter's Disease.

    2013-10-01

    Septic arthritis of the hip in neonates is rare but can have devastating consequences. Presenting signs and symptoms may differ from those encountered in older children, which may result in diagnostic challenge or delay. Many risk factors predispose neonates to septic arthritis, including the presence of transphyseal vessels and invasive procedures. Bacterial infection of the joint occurs via hematogenous invasion, extension from an adjacent site, or direct inoculation. A strong correlation exists between younger age at presentation and severity of residual hip deformity. Diagnosis is based on clinical examination, laboratory markers, and ultrasound evaluation. Early management includes parenteral antibiotics and surgical drainage. Late-stage management options include femoral and pelvic osteotomies, trochanteric arthroplasty, arthrodesis, pelvic support procedures, and nonsurgical measures. Early diagnosis and management continues to be the most important prognostic factor for a favorable outcome in the neonate with septic arthritis.

    Differentiating septic arthritis from culture-negative, acute atraumatic joint effusion is difficult. Studies have attempted to elucidate factors that herald infection, but, due to overlap, most conclude that the diagnosis ultimately relies on clinical judgment. Furthermore, studies are limited by broad inclusion criteria. The current retrospective case study sought to examine (1) which markers differentiate a culture-positive septic joint from culture-negative effusion in patients suspicious for infection despite no growth on Gram stain and without previous surgery in the affected joint and (2) whether threshold values of these markers exist that predict septic arthritis. The study was performed by reviewing records of those who underwent operative irrigation and debridement involving the shoulder, elbow, wrist, hip, knee, and ankle. Patients were included if they were older than 18 years and had an acutely swollen/painful joint and no organisms on initial Gram stain. Exclusion criteria were lack of serum markers or synovial fluid aspirate, antibiotics within 1 week, adjacent wound or skin infection, recent trauma to the joint, and previous joint infection or surgery to the joint. Several clinical, serological, and synovial parameters were collected and analyzed using paired t test with Bonferonni correction. Serum C-reactive protein was the only significantly different variable between groups. Serum C-reactive protein greater than 10.5 mg/dL was predictive of infection. In those suspicious for infection despite no growth on Gram stain and without previous surgery in the affected joint, C-reactive protein greater than 10.5 mg/dL is suspicious for joint sepsis and should warrant consideration for urgent irrigation and debridement.

    2014-01-01

    Aim. The present investigation was designed to evaluate antiarthritic potential of fractions of hydroalcoholic extract from leaves of P. alba. Materials and Methods. Plumeria alba L. leaves were extracted with hydroalcohol (30 : 70) to obtain hydroalcoholic extract of P. alba. This extract was further fractionated with solvents ethyl acetate and n-butanol to obtain EAPA and BPA, respectively. These fractions were tested against formaldehyde and Freund's complete adjuvant (FCA) induced arthritis. Arthritis assessment, paw volume, body weight, motor incoordination, and nociceptive threshold were measured. On day 21, the animals were sacrificed and histopathology was done. Results. The 100 and 200 mg/kg doses of EAPA and BPA caused a significant (P ≤ 0.05–0.01) reduction in paw swelling in both models. Erythrocyte sedimentation rate (ESR) and spleen weight decreased significantly (P < 0.01) in arthritic rats treated with extracts. There was significant (P < 0.05) improvement in thymus weight in EAPA treated rats whereas significant (P < 0.01) improvement was also seen in haemoglobin level (Hb) in diclofenac treated group. Motor incoordination and nociceptive threshold were also significantly (P ≤ 0.05–0.01) improved. Conclusion. The present study suggests that Plumeria alba L. has protective activity against arthritis and supports the traditional use of P. alba for rheumatism and other inflammatory diseases. PMID:25025056

    2012-10-01

    We describe a child with polyarticular juvenile idiopathic arthritis (JIA) presenting with severe diffuse pain refractory to nonsteroidal anti-inflammatory agents and high-dose opioids. Her JIA involved her knees and ankles and was mildly active on etanercept and nonsteroidal anti-inflammatory agents. At presentation, she complained of hip pain progressing to severe diffuse pain and allodynia involving her extremities. No abnormalities were seen in her laboratory parameters and imaging of her lower extremities. After appreciating no substantial benefit by increasing her opioids, her opioids were tapered and discontinued, and this was followed by significant alleviation in her pain, and a diagnosis of opioid-induced hyperalgesia (OIH) was made. Despite reports in adults, the phenomenon of OIH has been reported infrequently in children. To our knowledge, OIH has not been described in children with rheumatologic conditions. We recommend investigating the possibility of OIH when treating a child with JIA and severe refractory pain.

    2015-11-01

    Juvenile idiopathic arthritis (JIA) is the most common chronic arthritis of childhood. Currently, it is characterized by seven categories. The enthesitis-related arthritis (ERA) category usually affects boys older than 6 years and presents with lower limb asymmetrical arthritis associated with enthesitis. Later, these children can develop inflammatory lumbosacral pain (IBP). These children are at risk of developing acute anterior uveitis. A recently devised disease activity index, Juvenile Spondyloarthropathy Disease Activity Index (JSpADA), has been validated in retrospective cohorts. The corner stone of treatment is NSAIDs, local corticosteroid injections, and exercise. Methotrexate and sulfasalazine can be used for peripheral arthritis while anti-tumor necrosis factor (TNF) agents are sometimes used to treat refractory enthesitis and sacroiliitis. Almost two third of patients with ERA have persistent disease and often have impairments in their quality of life. The presence of hip or ankle arthritis and a family history of spondyloarthropathy or polyarticular joint involvement at onset are associated with poorer prognosis.

    Objective In this study, we evaluated the relationship between ferritin levels and disease activation in rheumatoid arthritis (RA) patients. Material and Methods We included 44 patients with RA, 20 patients with systemic lupus erythematosus (SLE), 25 patients with infection, 22 patients with malignancy, and 20 healthy control subjects. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), whole blood count, and serum iron parameters were determined in all cases. The joint findings in RA patients were recorded, and disease activity score (DAS) was calculated. In SLE patients, antinuclear antibody (ANA) and anti-dsDNA titers and C3 and C4 complement levels were determined. SLE disease activity index (SLEDAI) score was calculated. Results Serum ferritin levels in the RA, SLE, and control groups were lower than those in the infection and malignancy groups (p<0.05). The ferritin levels in the RA group did not differ significantly from the SLE and control groups. In RA patients, serum ferritin level had a positive correlation with ESR, CRP, RF, platelet count, and DAS score and had a negative correlation with hematocrit (all p values <0.05). In SLE patients, on the other hand, serum ferritin had a positive correlation with ANA, anti-dsDNA, and SLEDAI (all p values <0.05). According to DAS, ferritin level in inactive RA patients was lower than that in active RA patients. When transferrin saturation was considered, iron deficiency anemia was a quite frequent finding in both active and inactive RA patients. Conclusion Interestingly, we observed that ferritin level in RA patients was similar to the control group; however, it was a good parameter of disease activation. This is because a reduction in storage iron and resultant iron deficiency anemia are very common in RA patients.

    Objective Development of an in vivo imaging method to assess lymphatic draining function in the K/B×N mouse model of inflammatory arthritis. Methods Indocyanine green (ICG), a near-infrared (NIR) fluorescent dye, was injected intradermally into the footpad of wild-type mice, the limb was illuminated with an 806 nm NIR laser, and the movement of ICG from the injection site to the draining popliteal lymph node (PLN) was recorded with a CCD camera. ICG-NIR images were analyzed to obtain 5 measures of lymphatic function across time. K/B×N arthritic mice and control non-arthritic littermates were imaged at one-month of age when acute joint inflammation commenced, and repeated at 3 months when joint inflammation became chronic. Lymphangiogenesis in PLNs was assessed by immunochemistry. Results ICG and its transport within lymphatic vessels were readily visualized and quantitative measures derived. During the acute phase of arthritis, the lymphatic vessels were dilated with increased ICG signal intensity and lymphatic pulses, and PLNs became fluorescent quickly. During the chronic phase, new lymphatic vessels were present near the foot. However, ICG appearance in lymphatic vessels was delayed. The size and area of PLN lymphatic sinuses progressively increased in the K/B×N mice. Conclusion ICG-NIR lymphatic imaging is a valuable method to assess the lymphatic draining function in mice with inflammatory arthritis. ICG-NIR imaging of K/B×N mice identified two distinct lymphatic phenotypes during the acute and chronic phase of inflammation. This technique can be used to assess new therapies for lymphatic disorders. PMID:20309866

    The objective of the study was to identify risk factors for acute exacerbation of interstitial lung disease (ILD) during tocilizumab treatment in patients with rheumatoid arthritis (RA). This is a retrospective, case-control study. We reviewed 395 consecutive RA patients who received tocilizumab. First, we divided the patients according to the presence (RA-ILD) or absence of ILD (non-ILD) assessed by chest X-ray or high-resolution computed tomography, and compared them for characteristics relevant to RA-ILD. Subsequently, focusing on the patients with RA-ILD, we assessed their baseline characteristics and clinical courses comparing patients with acute exacerbation to those without. Comparing 78 with ILD and 317 without ILD, the following were identified as factors related to RA-ILD on multivariate analysis: age 60 years or older (OR 4.5, 95 % CI 2.2-9.4, P < 0.0001), smoking habit (OR 2.9, 95 % CI 1.5-5.5, P = 0.002), and high rheumatoid factor levels (OR 2.8, 95 % CI 1.4-5.5, P = 0.002). Of 78 RA-ILD patients, six developed acute exacerbation during tocilizumab treatment. The median duration between the initiation of tocilizumab treatment and the acute exacerbation occurrence was 48 weeks. While baseline characteristics did not differ between acute exacerbation and non-acute exacerbation groups, patients experiencing acute exacerbation had significantly higher Clinical Disease Activity Index (CDAI) at 24 weeks (20.8 vs. 6.2, P = 0.019). Univariate analysis showed that CDAI > 10 at 24 weeks was a risk factor for acute exacerbation (OR 4.7, 95 % CI 2.1-10.4, P = 0.02). Uncontrolled arthritis activity during tocilizumab treatment may be associated with acute exacerbation of RA-ILD, suggesting post-treatment monitoring of disease activity is important not only with respect to RA itself but also for RA-ILD.

  6. Isolated septic facet joint arthritis as a rare cause of acute and chronic low back pain – a case report and literature review

    PubMed Central

    Klekot, Dominika; Zimny, Anna; Czapiga, Bogdan; Sąsiadek, Marek

    2012-01-01

    Summary Background: The most common cause of low back pain is degenerative disease of the intervertebral disc and other structures of the lumbar spine. However, in some cases other less frequent causes of such pain can be seen, for example septic facet joint arthritis. Until now, only 40 cases of such inflammatory changes within the spine have been reported in the literature. The disease is probably underestimated due to improper diagnostic pathway. Case Report: The authors describe a case of a 53-year-old woman who was repeatedly hospitalized during a five-month period because of an acute, severe low back pain, with sphincter dysfunction, partially resembling sciatic symptoms. Physical examinations revealed also focal tenderness in the area of the lumbar spine. Inflammatory markers (ESR – erythrocyte sedimentation rate, CRP – C-reactive protein) were elevated. Conservative analgetic treatment brought only partial and temporary relief of the pain and symptoms. The final accurate diagnosis of isolated septic facet joint arthritis at the level of L5/S1 was established after several months from the onset of the first symptoms, after performing various imaging examinations, including bone scintigraphy as well as CT and MRI of the lumbosacral spine. The patient fully recovered after antibiotic therapy and surgery, which was proven in several follow-up examinations showing no relevant pathology of the lumbar spine. The authors broadly describe the etiology and clinical symptoms of the septic facet joint arthritis as well as the significant role of imaging methods, especially MRI, in diagnostic process. The authors also discuss currently available treatment options, both conservative and surgical. Conclusions: The diagnostic procedure of septic facet joint arthritis requires several steps to be taken. Establishing a correct diagnosis may be difficult, that is why it is important to remember about rare causes of low back pain and to perform detailed physical

    Objective We aimed to evaluate the safety and efficacy of a fixed-dose combination (FDC) of tramadol and diclofenac versus a standard approved FDC of tramadol and paracetamol, in patients with acute moderate to severe pain. Methods A total of 204 patients with moderate to severe pain due to acute musculoskeletal conditions (n=52), acute flare of osteoarthritis (n=52), acute flare of rheumatoid arthritis (n=50), or postoperative pain (n=50) were enrolled in the study at baseline. Each disease category was then randomized to receive either of two treatments for 5 days: group A received an FDC of immediate-release tramadol hydrochloride (50 mg) and sustained-release diclofenac sodium (75 mg) (one tablet, twice daily), and group B received an FDC of tramadol hydrochloride (37.5 mg) and paracetamol (325 mg) (two tablets every 4–6 hours, up to a maximum of eight tablets daily). The primary efficacy end points were reductions in pain intensity from baseline at day 3 and day 5 as assessed by a Visual Analog Scale (VAS) score. Results Group A showed a significant reduction in the VAS score for overall pain from baseline on day 3 (P=0.001) and day 5 (P<0.0001) as compared with group B. The combination of tramadol-diclofenac resulted in few mild to moderate adverse events (nausea, vomiting, epigastric pain, and gastritis), which required minimal management, without any treatment discontinuation. The number of adverse events in group A was nine (8.82%) compared with 22 (21.78%) in group B, after 5 days of treatment. Conclusion An FDC of tramadol-diclofenac showed a significantly greater reduction in pain intensity and was well tolerated compared with tramadol-paracetamol, resulting in better analgesia in patients suffering from moderate to severe pain due to acute musculoskeletal conditions, postoperative pain following orthopedic surgery, or acute flare of osteoarthritis and rheumatoid arthritis.

  8. Clinical disease activity and acute phase reactant levels are discordant among patients with active rheumatoid arthritis: acute phase reactant levels contribute separately to predicting outcome at one year

    PubMed Central

    2014-01-01

    Introduction Clinical trials of new treatments for rheumatoid arthritis (RA) typically require subjects to have an elevated acute phase reactant (APR), in addition to tender and swollen joints. However, despite the elevation of individual components of the Clinical Disease Activity Index (CDAI) (tender and swollen joint counts and patient and physician global assessment), some patients with active RA may have normal erythrocyte sedimentation rate (ESR) and/or C-reactive protein (CRP) levels and thus fail to meet entry criteria for clinical trials. We assessed the relationship between CDAI and APRs in the Consortium of Rheumatology Researchers of North America (CORRONA) registry by comparing baseline characteristics and one-year clinical outcomes of patients with active RA, grouped by baseline APR levels. Methods This was an observational study of 9,135 RA patients who had both ESR and CRP drawn and a visit at which CDAI was >2.8 (not in remission). Results Of 9,135 patients with active RA, 58% had neither elevated ESR nor CRP; only 16% had both elevated ESR and CRP and 26% had either ESR or CRP elevated. Among the 4,228 patients who had a one-year follow-up visit, both baseline and one-year follow-up modified Health Assessment Questionnaire (mHAQ) and CDAI scores were lowest for patients with active RA but with neither APR elevated; both mHAQ and CDAI scores increased sequentially with the increase in number of elevated APR levels at baseline. Each individual component of the CDAI followed the same trend, both at baseline and at one-year follow-up. The magnitude of improvement in both CDAI and mHAQ scores at one year was associated positively with the number of APRs elevated at baseline. Conclusions In a large United States registry of RA patients, APR levels often do not correlate with disease activity as measured by joint counts and global assessments. These data strongly suggest that it is appropriate to obtain both ESR and CRP from RA patients at the initial

    PubMed Central

    2016-01-01

    The aim of this study was to develop and validate a new radiographic damage scoring method (DAmagE index of GoUt; DAEGU) in chronic gout using plain radiography. Two independent observers scored foot x-rays from 15 patients with chronic gout according to the DAEGU method and the modified Sharp/van der Heijde (SvdH) method. The 10 metatarsophalangeal (MTP) and 2 interphalangeal (IP) joints of the first toes of both feet were scored to assess the degrees of erosion and joint space narrowing (JSN). The intraobserver and interobserver reliabilities were analyzed by calculating the intraclass correlation coefficient (ICC) and minimal detectable change (MDC). The correlation between the DAEGU and SvdH methods was analyzed by calculating the Spearman's rho correlation coefficients and Kappa coefficients. The DAEGU method was found to be highly reproducible (0.945–0.987 for the intraobserver and 0.993–0.996 for the interobserver ICC values). The erosion, JSN, and total scores exhibited strong positive correlations between the DAEGU and SvdH methods and also within each method (r = 0.860–0.969, P < 0.001 for all parameters). The DAEGU and SvdH methods were in very good agreement as determined by Kappa coefficient analysis [0.732 (0.387–1.000) for erosion and 1.000 (1.000–1.000) for JSN]. In conclusion, this study revealed that DAEGU method was a reliable and feasible tool in the assessment of radiographic damage in chronic gout. The DAEGU method may provide a more easy assessment of structural damage in chronic gout in the real clinical practice. PMID:26955246

  13. Striatal opioid receptor availability is related to acute and chronic pain perception in arthritis: does opioid adaptation increase resilience to chronic pain?

    The experience of pain in humans is modulated by endogenous opioids, but it is largely unknown how the opioid system adapts to chronic pain states. Animal models of chronic pain point to upregulation of opioid receptors (OpR) in the brain, with unknown functional significance. We sought evidence for a similar relationship between chronic pain and OpR availability in humans. Using positron emission tomography and the radiotracer (11)C-diprenorphine, patients with arthritis pain (n = 17) and healthy controls (n = 9) underwent whole-brain positron emission tomography scanning to calculate parametric maps of OpR availability. Consistent with the upregulation hypothesis, within the arthritis group, greater OpR availability was found in the striatum (including the caudate) of patients reporting higher levels of recent chronic pain, as well as regions of interest in the descending opioidergic pathway including the anterior cingulate cortex, thalamus, and periaqueductal gray. The functional significance of striatal changes were clarified with respect to acute pain thresholds: data across patients and controls revealed that striatal OpR availability was related to reduced pain perception. These findings are consistent with the view that chronic pain may upregulate OpR availability to dampen pain. Finally, patients with arthritis pain, compared with healthy controls, had overall less OpR availability within the striatum specifically, consistent with the greater endogenous opioid binding that would be expected in chronic pain states. Our observational evidence points to the need for further studies to establish the causal relationship between chronic pain states and OpR adaptation.

    Reactive arthritis is a rare complication of certain infections. The similar features and HLA associations with the seronegative arthropathies have raised the possibility that the latter may be forms of reactive arthritis. This review describes the clinical and epidemiological features, and the recent advances in our understanding of the underlying pathogenesis of reactive arthritis. PMID:7100033

    The septic arthritis literature of 2000 revisited several topics previously examined in some detail. These include septic arthritis in rheumatoid arthritis, rheumatic manifestations of bacterial endocarditis, and infectious complications of prosthetic joints. The trend in antibiotic prophylaxis to prevent late infections in total joint replacement is to narrow the targeted hosts to those most at risk, to define the procedures associated with the greatest risk of bacteremia, and to simplify the antibiotic regimen. The diagnoses of septic arthritis of the lumbar facet joint and septic arthritis caused by direct inoculation of bacteria by a foreign object penetrating the joint are facilitated by noninvasive imaging technologies. Septic arthritis caused by uncommon microorganisms and septic arthritis in immunocompromised hosts are other noteworthy topics in this year's literature. PMID:11555734

  20. Lyme arthritis of the pediatric ankle.

    2014-10-01

    Lyme arthritis results from acute inflammation caused by the spirochete Borrelia burgdorferi. The number of cases per year has been rising since 2006, with a majority of patients being affected in the northeastern United States. Development of Lyme arthritis is of particular importance to the orthopedic surgeon because Lyme arthritis often presents as an acute episode of joint swelling and tenderness and may be confused with bacterial septic arthritis. Considering the vast difference in treatment management between these 2 pathologies, differentiating between them is of critical importance. Septic arthritis often needs to be addressed surgically, whereas Lyme arthritis can be treated with oral antibiotics alone. Laboratory testing for Lyme disease often results in a delay in diagnosis because many laboratories batch-test Lyme specimens only a few times per week because of increased expense. The authors present a case of Lyme arthritis in the pediatric ankle in an endemic region. No clear algorithm exists to delineate between septic arthritis and Lyme arthritis of the joint. Improved clinical guidelines for the identification and diagnosis of Lyme arthritis of the ankle are important so that appropriate antibiotics can be used and surgery can be avoided.

    Tocilizumab, an anti-human interleukin 6 receptor (IL-6R) monoclonal antibody, is widely used to treat rheumatoid arthritis (RA) and is expected to exhibit clinical efficacy when used to treat other autoimmune diseases. However, a risk of opportunistic infection is occasionally recognized. A 54-year-old woman had received an oral corticosteroid and methotrexate to treat RA. Despite receiving these treatments, she received additional treatment with tocilizumab due to poor control of the disease activity. She presented at our hospital with a high fever and epigastralgia 19 days after receiving this treatment. A laboratory evaluation revealed liver injury and cytomegalovirus (CMV) viremia. Abdominal ultrasonography and computed tomography (CT) revealed hepatosplenomegaly, but no ascites. Upper gastrointestinal endoscopy revealed gastric erosions induced by CMV, which were confirmed immunohistochemically. Hence, we diagnosed the patient with CMV reactivation-induced acute hepatitis and gastric erosions under tocilizumab treatment. She received an anti-cytomegalovirus drug, ganciclovir, for 14 days due to her viremia and impaired general condition, which was suggestive of a severe infection. Her general condition subsequently improved, the liver function test results normalized, and the gastric erosions disappeared. In conclusion, although tocilizumab is very useful for treating certain autoimmune and inflammatory diseases, and will be prescribed more widely in the future, associated CMV infections must be closely monitored, as these can be lethal.

    Current diagnostic methods in differentiating septic from non-septic arthritis are time-consuming (culture) or have limited sensitivity (Gram stain). Microcalorimetry is a novel method that can rapidly detect microorganisms by their heat production. We investigated the accuracy and time to detection of septic arthritis by using microcalorimetry. Patients older than 18 years of age with acute arthritis of native joints were prospectively included. Synovial fluid was aspirated and investigated by Gram stain, culture and microcalorimetry. The diagnosis of septic arthritis and non-septic arthritis were made by experienced rheumatologists or orthopaedic surgeons. Septic arthritis was diagnosed by considering the finding of acute arthritis together with findings such as positive Gram stain or positive culture of synovial fluid or positive blood culture. The sensitivity and specificity for diagnosing septic arthritis and the time to positivity of microcalorimetry were determined. Of 90 patients (mean age 64 years), nine had septic arthritis, of whom four (44 %) had positive Gram stain, six (67 %) positive synovial fluid culture and four (44 %) had positive blood culture. The sensitivity of microcalorimetry was 89 %, the specificity was 99 % and the mean detection time was 5.0 h (range, 2.2-8.0 h). Microcalorimetry is an accurate and rapid method for the diagnosis of septic arthritis. It has potential to be used in clinical practice in diagnosing septic arthritis.

  6. Prospective surveillance study of acute respiratory infections, influenza-like illness and seasonal influenza vaccine in a cohort of juvenile idiopathic arthritis patients

    PubMed Central

    2013-01-01

    Background Acute respiratory infections (ARI) are frequent in children and complications can occur in patients with chronic diseases. We evaluated the frequency and impact of ARI and influenza-like illness (ILI) episodes on disease activity, and the immunogenicity and safety of influenza vaccine in a cohort of juvenile idiopathic arthritis (JIA) patients. Methods Surveillance of respiratory viruses was conducted in JIA patients during ARI season (March to August) in two consecutive years: 2007 (61 patients) and 2008 (63 patients). Patients with ARI or ILI had respiratory samples collected for virus detection by real time PCR. In 2008, 44 patients were immunized with influenza vaccine. JIA activity index (ACRPed30) was assessed during both surveillance periods. Influenza hemagglutination inhibition antibody titers were measured before and 30-40 days after vaccination. Results During the study period 105 ARI episodes were reported and 26.6% of them were ILI. Of 33 samples collected, 60% were positive for at least one virus. Influenza and rhinovirus were the most frequently detected, in 30% of the samples. Of the 50 JIA flares observed, 20% were temporally associated to ARI. Influenza seroprotection rates were higher than 70% (91-100%) for all strains, and seroconversion rates exceeded 40% (74-93%). In general, response to influenza vaccine was not influenced by therapy or disease activity, but patients using anti-TNF alpha drugs presented lower seroconversion to H1N1 strain. No significant differences were found in ACRPed30 after vaccination and no patient reported ILI for 6 months after vaccination. Conclusion ARI episodes are relatively frequent in JIA patients and may have a role triggering JIA flares. Trivalent split influenza vaccine seems to be immunogenic and safe in JIA patients.

    We document the case of a 7-year-old boy who presented with pain in his left ear and trismus after a diagnosis of acute otitis media one week previously. His blood inflammatory markers were raised and magnetic resonance imaging (MRI) showed significant left temporomandibular joint effusion and partial attenuation of the left mastoid. A clinical diagnosis of septic arthritis of the TMJ was made and the patient was commenced on broad-spectrum antibiotics. Analysis using real time PCR enabled identification of the offending organism, confirmation of the diagnosis and antibiotic treatment to be specifically tailored for treatment.

  9. Rheumatoid arthritis.

    2010-09-25

    Rheumatoid arthritis is characterised by persistent synovitis, systemic inflammation, and autoantibodies (particularly to rheumatoid factor and citrullinated peptide). 50% of the risk for development of rheumatoid arthritis is attributable to genetic factors. Smoking is the main environmental risk. In industrialised countries, rheumatoid arthritis affects 0·5-1·0% of adults, with 5-50 per 100 000 new cases annually. The disorder is most typical in women and elderly people. Uncontrolled active rheumatoid arthritis causes joint damage, disability, decreased quality of life, and cardiovascular and other comorbidities. Disease-modifying antirheumatic drugs (DMARDs), the key therapeutic agents, reduce synovitis and systemic inflammation and improve function. The leading DMARD is methotrexate, which can be combined with other drugs of this type. Biological agents are used when arthritis is uncontrolled or toxic effects arise with DMARDs. Tumour necrosis factor inhibitors were the first biological agents, followed by abatacept, rituximab, and tocilizumab. Infections and high costs restrict prescription of biological agents. Long-term remission induced by intensive, short-term treatment selected by biomarker profiles is the ultimate goal.

    A detailed clinical and radiological examination of the joints and laboratory studies were carried out on 139 haemophiliacs attending a single centre. The group included more patients with mild and moderate haemophilia (factor levels 6 to 60 per cent) than in previous studies. Haemarthrosis, the most common bleeding manifestation, had affected more than two-thirds of patients including many with mild or moderate disease. Restriction and contracture of the knees and elbows were the most common clinical features and, with the ankles, these joints were most frequently affected both clinically and radiologically. Using a combination of clinical and radiological features, 42 per cent of the patients could be classed as having 'definite' and a further 14 per cent 'possible' haemophilic arthritis. Although haemarthroses were equally prevalent in patients with classical haemophilia and Christmas disease, arthritis was more frequently present in the former. Haemarthrosis and joint disease were exceptional in von Willebrand's disease. The prevalence of arthritis generally related to disease severity as measured by factor level but, in contrast to earlier studies, definite arthritis was seen in some patients with factor levels up to 20 per cent of normal although the number of affected joints was less in these patients with milder disease. Laboratory test abnormalities including circulating immune complexes and hypocomplementaemia were noted in some patients but the abnormalities correlated poorly with clinical features. The present results suggest a recent slight reduction in the prevalence or severity of haemophilic arthritis, possibly attributable to recent improvements in factor replacement treatment. Longer-term studies are required to show whether arthritis is indeed lessening or whether the onset is merely being delayed.

    Aicardi–Goutières syndrome is a leukoencephalopathy with calcifications and increased cerebrospinal fluid interferon-α. The relation between interferon-α and brain pathology is poorly understood. We report a patient with mutations in the disease-associated gene SAMHD1. Neuropathology showed an extensive microangiopathy with calcifications consistently associate with blood vessels. In an in vitro model of the microangiopathy, interferon-α enhanced vascular smooth muscle cell-derived calcifications. The noninfarcted white matter harbored apoptotic oligodendrocytes and increased numbers of oligodendrocyte progenitors. These findings better define the white matter pathology and provide evidence that interferon-α plays a direct pathogenetic role in the calcifying angiopathy typical of this disease. PMID:26273690

    The aim of this study was to observe the effects of uric acid lowering therapy (UALT), febuxostat and allopurinol, on blood pressure (BP) and serum creatinine level. Post-hoc data were derived from a phase-III, randomised, double-blind, 4-week trial of male gouty patients that compared the safety and efficacy of febuxostat and allopurinol in adults with gout. The subjects were randomly assigned to one of five groups, 35-37 in each group (febuxostat: 40, 80, 120 mg/d; allopurinol: 300 mg/d; control group: placebo). Blood pressure and serum creatinine level were measured at baseline and at weeks 2 and 4. Diastolic BP and creatinine level had decreased significantly in the UALT groups compared to the control group at week 4. Diastolic BP had decreased significantly in the allopurinol group and serum creatinine level had decreased significantly in the febuxostat groups at week 4. After adjusting for confounding variables, serum uric acid changes were found to be significantly correlated with changes in serum creatinine level but were not associated with changes in systolic or diastolic BP. UALT in gouty subjects significantly decreased diastolic BP and serum creatinine level. Changes in uric acid were significantly correlated with those in serum creatinine level, suggesting the feasibility of renal function improvement through UALT in gouty men.

    Objective To assess the value of MicroPure, a new ultrasound image processing technique, in identifying microcalcifications (formed by monosodium urate crystals) in the first metatarsophalangeal joints attacked by gout compared to gray-scale ultrasound images. Materials and Methods Thirty-six patients who fulfilled the study inclusion criteria underwent gray-scale ultrasound and MicroPure examinations of the first metatarsophalangeal joints attacked by gout. Static images of the target areas were acquired using gray-scale ultrasound and MicroPure. Two independent and blinded investigators analyzed the images to determine the number of microcalcifications and to score for image quality and artifacts. Results The two investigators observed significantly more microcalcifications with MicroPure compared to gray-scale ultrasound (ρ<0.001). The level of agreement between the investigators consistently increased from gray-scale ultrasound to MicroPure imaging (gray-scale interclass correlation coefficient of 0.69 vs. MicroPure interclass correlation coefficient of 0.81). One investigator preferred the MicroPure image quality over gray-scale ultrasound (ρ<0.001), but the other investigator disagreed (ρ<0.001). Both investigators observed fewer artifacts with MicroPure than with gray-scale ultrasound (ρ<0.009). Conclusion MicroPure imaging identified significantly more microcalcifications than gray-scale ultrasound. PMID:24788200

    The development of novel anti-rheumatic drugs revolutionizes currently therapeutic strategies and diagnostic management of patients with rheumatoid arthritis, facilitating the goal of true remission instead of only symptomatic treatment as in former years. Since early treatment is known to be crucial for the longterm outcome, imaging modalities such as magnetic resonance imaging and high-frequency ultrasonography including Doppler sonography, which allow direct visualization of very early pathologic alterations of synovitis, or even initial destruction, become increasingly important. Besides the established therapy with methotrexate, new drugs such as leflunomide or the use of various combination therapies have been successfully introduced into the therapeutic armamentarium. Especially the introduction of cytokine-antagonists such as TNF-a inhibitors target the aim of remission. In addition, the upcoming therapeutic agents, which influence very effectively the inflammatory and destructive process need also to be integrated into the concert of different therapeutic strategies in the management of patients with rheumatoid arthritis, which includes the mandatory complementary factors such as physiotherapy, ergotherapy and orthopedic surgery.

    Berries are an important dietary source of fibres, vitamins, minerals and some biologically active non-nutrients. A red raspberry fruit extract was characterized in terms of phenolic content and the anti-inflammatory properties and protective effects were evaluated in two experimental models of inflammation. The antioxidant potential of the extract, the cellular antioxidant activity and the effects over neutrophils' oxidative burst were also studied to provide a mechanistic insight for the anti-inflammatory effects observed. The extract was administered in a dose of 15 mg kg(-1), i.p. and significantly inhibited paw oedema formation in the rat. The same dose was administered via i.p. and p.o. routes in the collagen-induced arthritis model in the rat. The extract showed pharmacological activity and was able to significantly reduce the development of clinical signs of arthritis and markedly reduce the degree of bone resorption, soft tissue swelling and osteophyte formation, preventing articular destruction in treated animals.

    1993-01-01

    The menstrual cycle is characterised by variations in the absolute and relative concentrations of the hormones of the hypothalamic pituitary ovarian axis, which in turn affect cell function and cytokine and heat shock protein production. Menstruation involves the shedding of the secretory endometrium, which is part of the mucosal associated lymphoid tissue and hence is rich in immunologically competent cells such as CD8 T cells and macrophages. The case is reported here of a patient presenting with a recurrent but transient symmetrical inflammatory polyarthritis which only occurred at menstruation with no residual damage. The disease was suppressed by danazol. Endometrial degradation products are suggested as the trigger of this 'menstrual arthritis'. PMID:8427519

  2. Aicardi-Goutières syndrome: clues from the RNase H2 knock-out mouse.

    PubMed

    Rabe, Björn

    2013-11-01

    Ribonuclease H2 (RNase H2) belongs to the family of RNase H enzymes, which process RNA/DNA hybrids. Apart from cleaving the RNA moiety of a plain RNA/DNA hybrid, RNase H2 participates in the removal of single ribonucleotides embedded in a DNA duplex. Mutations in RNase H2 lead to the chronic inflammatory disorder Aicardi-Goutières syndrome (AGS), which has significant phenotypic overlaps with the autoimmune disease systemic lupus erythematosus. RNase H2 knock-out mice are embryonic lethal. Mouse embryos lacking RNase H2 accumulate DNA damage and exhibit a p53-mediated growth arrest commencing at gastrulation. On a molecular level, the knock-out mice reveal that RNase H2 represents an essential DNA repair enzyme, whose main cellular function is the removal of accidentally misincorporated ribonucleotides from genomic DNA. Ribonucleotides strongly accumulate within the genomic DNA of RNase H2-deficient cells, in turn resulting in a massive build-up of DNA damage in these cells. The DNA lesions that arise from misincorporated ribonucleotides constitute the by far most frequent type of naturally occurring DNA damage. AGS-causing mutations have also been found in the genes of the 3'-exonuclease TREX1, the dNTP triphosphatase SAMHD1, as well as the RNA-editing enzyme ADAR1, defining defects in nucleic acid metabolism pathways as a common hallmark of AGS pathology. However, recent evidence gathered from RNase H2 knock-out mice might provide additional insight into the molecular mechanisms underlying AGS development and a potential role of DNA damage as a trigger of autoimmunity is discussed.

    Aicardi-Goutières syndrome (AGS) is a genetic encephalopathy whose clinical features mimic those of acquired in utero viral infection. AGS exhibits locus heterogeneity, with mutations identified in genes encoding the 3′→5′ exonuclease TREX1 and the three subunits of the RNASEH2 endonuclease complex. To define the molecular spectrum of AGS, we performed mutation screening in patients, from 127 pedigrees, with a clinical diagnosis of the disease. Biallelic mutations in TREX1, RNASEH2A, RNASEH2B, and RNASEH2C were observed in 31, 3, 47, and 18 families, respectively. In five families, we identified an RNASEH2A or RNASEH2B mutation on one allele only. In one child, the disease occurred because of a de novo heterozygous TREX1 mutation. In 22 families, no mutations were found. Null mutations were common in TREX1, although a specific missense mutation was observed frequently in patients from northern Europe. Almost all mutations in RNASEH2A, RNASEH2B, and RNASEH2C were missense. We identified an RNASEH2C founder mutation in 13 Pakistani families. We also collected clinical data from 123 mutation-positive patients. Two clinical presentations could be delineated: an early-onset neonatal form, highly reminiscent of congenital infection seen particularly with TREX1 mutations, and a later-onset presentation, sometimes occurring after several months of normal development and occasionally associated with remarkably preserved neurological function, most frequently due to RNASEH2B mutations. Mortality was correlated with genotype; 34.3% of patients with TREX1, RNASEH2A, and RNASEH2C mutations versus 8.0% RNASEH2B mutation–positive patients were known to have died (P=.001). Our analysis defines the phenotypic spectrum of AGS and suggests a coherent mutation-screening strategy in this heterogeneous disorder. Additionally, our data indicate that at least one further AGS-causing gene remains to be identified. PMID:17846997

    Summary Cutaneous lesions described as chilblain lupus occur in the context of familial chilblain lupus or Aicardi–Goutières syndrome. To date, seven genes related to Aicardi–Goutières syndrome have been described. The most recently described encodes the cytosolic double-stranded RNA receptor IFIH1 (also known as MDA5), a key component of the antiviral type I interferon-mediated innate immune response. Enhanced type I interferon signalling secondary to gain-of-function mutations in IFIH1 can result in a range of neuroinflammatory phenotypes including classical Aicardi–Goutières syndrome. It is of note that none of the patients with a neurological phenotype so far described with mutations in this gene was reported to demonstrate cutaneous involvement. We present a family segregating a heterozygous pathogenic mutation in IFIH1 showing dermatological involvement as a prominent feature, variably associated with neurological disturbance and premature tooth loss. All three affected individuals exhibited increased expression of interferon-stimulated genes in whole blood, and the mutant protein resulted in enhanced interferon signalling in vitro, both in the basal state and following ligand stimulation. Our results further extend the phenotypic spectrum associated with mutations in IFIH1, indicating that the disease can be confined predominantly to the skin, while also highlighting phenotypic overlap with both Aicardi–Goutières syndrome and Singleton–Merten syndrome.

    Long interspersed elements 1 (LINE-1) occupy at least 17% of the human genome and are its only active autonomous retrotransposons. However, the host factors that regulate LINE-1 retrotransposition are not fully understood. Here, we demonstrate that the Aicardi-Goutières syndrome gene product SAMHD1, recently revealed to be an inhibitor of HIV/simian immunodeficiency virus (SIV) infectivity and neutralized by the viral Vpx protein, is also a potent regulator of LINE-1 and LINE-1-mediated Alu/SVA retrotransposition. We also found that mutant SAMHD1s of Aicardi-Goutières syndrome patients are defective in LINE-1 inhibition. Several domains of SAMHD1 are critical for LINE-1 regulation. SAMHD1 inhibits LINE-1 retrotransposition in dividing cells. An enzymatic active site mutant SAMHD1 maintained substantial anti-LINE-1 activity. SAMHD1 inhibits ORF2p-mediated LINE-1 reverse transcription in isolated LINE-1 ribonucleoproteins by reducing ORF2p level. Thus, SAMHD1 may be a cellular regulator of LINE-1 activity that is conserved in mammals.

    The authors studied the histopathologic evolution of arthritis in nonirradiated and irradiated hamsters infected with Borrelia burgdorferi. Nonirradiated hamsters injected in the hind paws with B. burgdorferi developed an acute inflammatory reaction involving the synovium, periarticular soft tissues, and dermis. This acute inflammatory reaction was short-lived and was replaced by a mild chronic synovitis as the number of detectable spirochetes in the synovium, periarticular soft tissues, and perineurovascular areas diminished. Exposing hamsters to radiation before inoculation with B. burgdorferi exacerbated and prolonged the acute inflammatory phase. Spirochetes also persisted longer in the periarticular soft tissues. A major histopathologic finding was destructive and erosive bone changes of the hind paws, which resulted in deformation of the joints. These studies should be helpful in defining the immune mechanism participating in the onset, progression, and resolution of Lyme arthritis.

    Background To facilitate the development of therapies for rheumatoid arthritis (RA), the Innovative Medicines Initiative BTCure has combined the experience from several laboratories worldwide to establish a series of protocols for different animal models of arthritis that reflect the pathogenesis of RA. Here, we describe chronic pristane-induced arthritis (PIA) model in DA rats, and provide detailed instructions to set up and evaluate the model and for reporting data. Methods We optimized dose of pristane and immunization procedures and determined the effect of age, gender, and housing conditions. We further assessed cage-effects, reproducibility, and frequency of chronic arthritis, disease markers, and efficacy of standard and novel therapies. Results Out of 271 rats, 99.6% developed arthritis after pristane-administration. Mean values for day of onset, day of maximum arthritis severity and maximum clinical scores were 11.8±2.0 days, 20.3±5.1 days and 34.2±11 points on a 60-point scale, respectively. The mean frequency of chronic arthritis was 86% but approached 100% in long-term experiments over 110 days. Pristane was arthritogenic even at 5 microliters dose but needed to be administrated intradermally to induce robust disease with minimal variation. The development of arthritis was age-dependent but independent of gender and whether the rats were housed in conventional or barrier facilities. PIA correlated well with weight loss and acute phase reactants, and was ameliorated by etanercept, dexamethasone, cyclosporine A and fingolimod treatment. Conclusions PIA has high incidence and excellent reproducibility. The chronic relapsing-remitting disease and limited systemic manifestations make it more suitable than adjuvant arthritis for long-term studies of joint-inflammation and screening and validation of new therapeutics.

    One hundred consecutive patients admitted to an acute geriatric unit were examined for evidence of peripheral arthritis with recognised criteria used to define osteoarthritis, rheumatoid arthritis, pyrophosphate arthropathy, gout, and disorders of the shoulder joint. The presence of arthritis and its severity were related both to functional independence and to a recognition by the patient that joint problems were impairing independence. Seventy six patients had clinical peripheral arthritis; 48 had arthritis contributing to loss of function, and 19 of these did not volunteer evidence of their joint disease. The common occurrence of arthritic conditions in the elderly, with consequential disability and dependency, suggests that increased medical awareness may be required to prevent unnecessary morbidity. Our findings need confirmation in community based studies. PMID:2930278

    The role of trace elements bound to proteins in the etiology and pathogenesis of rheumatoid arthritis (RA) remains unclear. In this sense, the identification and detection of metalloproteins has a strong and growing interest. Metalloprotein studies are currently carried out by polyacrylamide gel electrophoresis (PAGE) associated to inductively coupled plasma mass spectrometry (ICPMS), and despite that complete information can be obtained for metals such as Fe, Cu and Zn, difficulties due to poor sensitivity for other trace elements such as Sn, As, etc, are currently faced. In the present work, a simple and fast method for the determination of trace metals bound to synovial fluid (SF) proteins was optimized. Proteins from SF (long and short-term RA) were separated in ten fractions by native PAGE, then dissolved in nitric acid and peroxide hydrogen, and analyzed by ICPMS. Fifteen metals were determined in each separated protein fraction (band). Adequate calibration of proteins molecular weight allowed stablishing which protein type were bound to different metals.

  15. Arthritis: joints inflamed.

    PubMed

    Casey, Georgina

    2015-06-01

    ARTHRITIS IS a generic term for inflammatory joint disease. There are various forms of arthritis, including osteoarthritis, rheumatoid arthritis and spondyloarthritis. Arthritis can be a chronic debilitating condition or a transient effect of bacterial or viral infections. As a chronic condition, arthritis can cause loss of quality of life, disability and, with rheumatoid disease, early death. The economic burden of arthritis, in terms of management and loss of productivity due to disability, is high and set to increase with the ageing population. Recent advances in our understanding of the causes and progression of a number of forms of arthritis have raised hopes of better management and possible remission. Pharmacotherapy has moved from symptom management to addressing underlying disease processes. However, therapies that prevent or cure arthritis remain elusive. Current care for people with arthritis relies on a multidisciplinary approach and substantial pharmacological intervention. Nurses have a key role to play in guiding patients through treatment, ensuring they receive optimal therapy to reduce the impact of arthritis and its management on their lives.

    The pathological invasion of a joint and subsequent inflammation is known as septic arthritis. The knee and hip are the most frequently involved joints. Staphylococcus aureus is the most common cause of septic arthritis in children. An acute onset of illness with an inflamed painful joint and restricted movements and inability to use joint (pseudoparalysis) clinically indicates septic arthritis. The diagnosis is difficult in a neonate or young child where refusal to feed, crying, discomfort during change of diaper (if hip is involved) or attempted joint movement may be the only findings. Fever and other systemic signs may also be absent in neonates. Septic arthritis is diagnosed clinically, supported by appropriate radiological and laboratory investigations. The peripheral blood white cell count is frequently raised with a predominance of polymorphonuclear cells. The acute phase reactants such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are often markedly raised. Ultrasonography and MRI are preferred investigations in pediatric septic arthritis. Determination of infecting organism in septic arthritis is the key to the correct antibiotic choice, treatment duration and overall management. Joint aspirate and/or blood culture should be obtained before starting antibiotic treatment. Several effective antibiotic regimes are available for managing septic arthritis in children. Presence of large collections, thick pus, joint loculations and pus evacuating into surrounding soft tissues are main indications for surgical drainage. Joint aspiration can be a practical alternative in case the lesion is diagnosed early, with uncomplicated presentations and superficial joints. PMID:26189923

    Septic arthritis of the temporomandibular joint (TMJ) is a rare disease. The most common symptoms of this disease are acute malocclusion, limited mouth opening, swelling, and tenderness of affected TMJ. These symptoms are often confused with internal derangement of the articular disc, rheumatoid arthritis, retrodiscitis, or osteoarthritis. Therefore, differential diagnosis by image examination is required. Usually, antimicrobial treatment and surgical drainage by needle aspiration, arthroscopy, or arthrotomy are effective treatment approaches. In this study, a patient who was diagnosed with septic arthritis was treated with arthrocentesis and antibiotics without significant complications. We present a case report with a review of the literature.

    OBJECTIVES—Reactive joint complications triggered by salmonella gastroenteritis are increasingly reported, but the outcome and long term prognosis of the patients is incompletely known. This study looked at the prognosis of salmonella arthritis in patients hospitalised in 1970-1986.
METHODS—Hospital records from two hospitals in southern Finland were screened for patients with the discharge diagnosis of salmonellosis or reactive, postinfectious arthritis or Reiter's disease. For the patients with confirmed diagnosis of reactive salmonella arthritis, data about the acute disease were collected from the hospital records. A follow up study was performed.
RESULTS—There were 63 patients (28 women, 35 men, mean age 36.5 years) with salmonella arthritis. Urethritis occurred in 27%, eye inflammation in 13%, and low back pain in 44% of the patients. HLA-B27 was present in 88%. More men than women were HLA-B27 positive. HLA-B27 positive patients had higher erythrocyte sedimentation rate (mean 80.9 v 46.5 mm 1st h, p = 0.0180). Also, extra-articular features and radiological sacroiliitis were seen only in HLA-B27 positive patients. A follow up study was performed on 50 patients mean 11.0 (range 5-22 years) later. Twenty patients had recovered completely. Ten patients had mild joint symptoms, 11 patients had had a new acute transient arthritis, and five acute iritis. Eight patients had developed chronic spondyloarthropathy. Radiological sacroiliitis was seen in six of 44 patients, more frequently in male than in female patients (32% v 0%; p = 0.0289). Recurrent or chronic arthritis, iritis or radiological sacroiliitis developed only in HLA-B27 positive patients.
CONCLUSION—Joint symptoms are common after reactive salmonella arthritis. HLA-B27 contributes to the severity of acute disease and to the late prognosis.

    Adenosine deaminases acting on RNA (ADARs) catalyze the hydrolytic deamination of adenosine to inosine in double-stranded RNA (dsRNA) and thereby potentially alter the information content and structure of cellular RNAs. Notably, although the overwhelming majority of such editing events occur in transcripts derived from Alu repeat elements, the biological function of non-coding RNA editing remains uncertain. Here, we show that mutations in ADAR1 (also known as ADAR) cause the autoimmune disorder Aicardi-Goutières syndrome (AGS). As in Adar1-null mice, the human disease state is associated with upregulation of interferon-stimulated genes, indicating a possible role for ADAR1 as a suppressor of type I interferon signaling. Considering recent insights derived from the study of other AGS-related proteins, we speculate that ADAR1 may limit the cytoplasmic accumulation of the dsRNA generated from genomic repetitive elements.

    Eleven cases of infectious arthritis occurring in patients with rheumatoid arthritis are reported. Staphylococcus aureus was the causative organism in eight patients. Streptococcus anginosus and Streptococcus agalactiae in one patient each, and Mycobacterium tuberculosis in two patients. The mean duration of symptoms before diagnosis was 16 days in patients with pyogenic arthritis. The diagnosis of joint infection caused by Mycobacterium tuberculosis was especially delayed (57 days). Four patients died; they were found to have a longer time to diagnosis and two of them had multiple joint infection. Although Staphylococcus aureus is the microorganism most often affecting patients with rheumatoid arthritis, infection caused by Mycobacterium tuberculosis must also be considered in such patients.

    The present study aimed to investigate the effects of a minimally invasive laser needle system (MILNS) on the acute progression of arthritis. Previous studies showed controversial clinical results regarding the effects of low-level laser therapy on arthritis, with the outcomes depending upon stimulation parameters such as laser wavelength and dosage. Based on the positive effects of MILNS on osteoporotic mice, we hypothesized that MILNS could potentially suppress the progression of arthritis owing to its biostimulation effects. Eight C57BL/6 mice with complete Freund's adjuvant (CFA)-induced arthritis were used as acute progression arthritis models and divided into the laser and control groups (n = 4 each). In the laser group, after minimally invasive laser stimulation, laser speckle contrast images (LSCIs) were obtained every 6 h for a total of 108 h. The LSCIs in the control group were obtained without laser stimulation. The effects of MILNS on the acute progression of arthritis were indirectly evaluated by calculating the paw area and the average laser speckle index (LSI) at the arthritis-induced area. Moreover, the macrophage population was estimated in the arthritis-induced area. Compared to the control group, the laser group showed (1) lower relative variations of the paw area, (2) lower average LSI in the arthritis-induced area, and (3) lower macrophage population in the arthritis-induced area. These results indicate that MILNS may suppress the acute progression of CFA-induced arthritis in mice and may thus be used as a potential treatment modality of arthritis in clinics.

    ABSTRACT Postinfectious arthritis is a relatively often encountered in pediatric practice. The authors present the most important data concerneing this pathology, with up to date informations exemplifying with case presentations. Clinical cases bring to attention the most common forms of postinfectious arthritis (reactive arthritis, postinfectious arthritis bacterial, viral, spirochete, and so on). Although highly studied and commonly found in current pediatric practice, arthritis occurring after infections remains controversial entities, especially regarding terminology. While, according to some authors, postinfectious arthritis belongs to the large group of reactive arthritis, by other authors, these joint events are independent entities. PMID:24371480

    Immunosuppressants have been the mainstay of treatment for certain inflammatory joint conditions for many years. Developments in this field, namely biological treatments, have led to a change in the classical presentation of acute bone, joint and soft tissue infections. The normal findings of severe pain and tenderness on examination may be absent or simply mimic a typical exacerbation of the chronic joint condition. A minimally raised white cell count and elevated C-reactive protein in the absence of systemic signs of infection may be interpreted as further evidence for the diagnosis of an exacerbation of inflammatory arthritis. We present a unique case of recurrent polyarticular septic arthritis in a patient treated with immunosuppression for refractory rheumatoid arthritis. We hope this article will enable doctors to appreciate and recognise the changing face of septic arthritis in the modern era of immunosuppressant treatments.

    Septic arthritis and spondylitis in elderly adult are uncommon disease. But symptoms and signs of septic arthritis and spondylitis are an important medical emergency, with high mortality and morbidity. Delayed or inadequate treatment can result in irreversible joint destruction and neurological condition. Early diagnoses as well as prompt and effective treatment are essential for avoiding severe outcomes. In spite of advances in diagnostic imaging techniques, the incidence of septic arthritis and spondylitis appears to have been increased. The aging of the population, the widespread use of immunosuppressant therapies, including systemic corticosteroids, cytokines and anticytokines, and growing resistance to conventional antibiotics seem to be the major cause.

    Aicardi–Goutières syndrome (AGS) is a severe childhood inflammatory disorder that shows clinical and genetic overlap with systemic lupus erythematosus (SLE). AGS is thought to arise from the accumulation of incompletely metabolized endogenous nucleic acid species owing to mutations in nucleic acid-degrading enzymes TREX1 (AGS1), RNase H2 (AGS2, 3 and 4), and SAMHD1 (AGS5). However, the identity and source of such immunogenic nucleic acid species remain undefined. Using genome-wide approaches, we show that fibroblasts from AGS patients with AGS1-5 mutations are burdened by excessive loads of RNA:DNA hybrids. Using MethylC-seq, we show that AGS fibroblasts display pronounced and global loss of DNA methylation and demonstrate that AGS-specific RNA:DNA hybrids often occur within DNA hypomethylated regions. Altogether, our data suggest that RNA:DNA hybrids may represent a common immunogenic form of nucleic acids in AGS and provide the first evidence of epigenetic perturbations in AGS, furthering the links between AGS and SLE.

    Acute monoarthritis is a common medical emergency with wide differential diagnosis. Common underlying causes include trauma, septic arthritis, crystal induced arthritis (gout and pseudogout), and reactive arthritis. Of these, septic arthritis is the diagnosis not to miss because of its association with significant morbidity and mortality. Precise diagnosis of the underlying cause of monoarthritis relies on a good history, physical examination findings, and results of focussed investigations. In this article, a practical approach to diagnosis and initial management of patients presenting with acute monoarthritis is described with the aid of a case vignette.

We found that irradiated LSH/Ss Lak hamsters developed arthritis after injection of Borrelia burgdorferi in the hind paws. When nonirradiated hamsters were injected in the hind paws with B. burgdorferi, acute transient synovitis was present. A diffuse neutrophilic infiltrate involved the synovia and periarticular structures. The inflammation was associated with edema, hyperemia, and granulation tissue. Numerous spirochetes were seen in the synovial and subsynovial tissues. The histopathologic changes were enhanced in irradiated hamsters. The onset and duration of the induced swelling were dependent on the dose of radiation and the inoculum of spirochetes. Inoculation of irradiated hamsters with Formalin-killed spirochetes or medium in which B. burgdorferi had grown for 7 days failed to induce swelling. This animal model should prove useful for studies of the immune response to B. burgdorferi and the pathogenesis of Lyme arthritis.

  1. Aeromonas hydrophila septic arthritis.

    PubMed

    Danaher, Patrick J; Mueller, William P

    2011-12-01

    Septic arthritis is a serious, life and limb threatening infection. If suspected, empiric treatment must begin immediately and account for the most likely pathogens. Eight days following left knee arthroscopic surgery, a 51-year-old active duty male spent approximately 1 hour driving a personal watercraft on Okaloosa Bay near the Gulf of Mexico. Eight days later, he presented to the emergency room with septic arthritis of that knee. Fluid aspirated from the joint yielded Aeromonas hydrophila. The infection resolved with surgical drainage and 21 days of levofloxacin. A. hydrophila is a rare cause of septic arthritis, and reported cases have involved exposure to water after trauma to the affected joint. Many U.S. military bases are located in coastal areas and military members frequently participate in activities which compromise skin integrity and place them at increased risk for contracting waterborne infections. We present the ninth case of A. hydrophila septic arthritis described in the English language literature, highlight the importance of considering this pathogen in at-risk populations, and review the diagnosis and management of septic arthritis.

    Infantile temporomandibular joint septic arthritis is an uncommon paediatric infection, but one which carries the potential for severe morbidity and mortality. Early diagnosis and aggressive medical and possibly surgical management is indicated for the best outcomes. The presenting clinical features are non-specific in a neonate and an infant; as such a high degree of clinical suspicion is required. We present the case of an eleven-month-old boy who has made a full recovery from an acute temporomandibular joint septic arthritis and review the relevant literature.

    We report a case of septic arthritis caused by a Bacillus species, B. pumilus, occurring in a healthy child. This organism rarely causes serious infections and has only been described in newborns and immunocompromised individuals or as a skin infection. This child developed an indolent joint swelling after a minor skin injury, and symptoms were initially thought most consistent with chronic arthritis. The case demonstrates that clinicians should consider joint infection in children presenting with acute monoarticular swelling, even without prominent systemic features. PMID:27366165

    Patients with rheumatoid arthritis have been referred to Division of Human Genetics for counselling. Qualitative dermatoglyphics comprising of finger print pattern, interdigital pattern, hypothenar pattern and palmar crease were studied on 26 female and 11 male rheumatoid arthritis patients. Comparison between patient male and control male; and patient female and control female has been done. 'Chi' square test was performed. In male patients, with hands together, arches were increased, loops/ whorls were decreased. Partial Simian crease was significantly increased. In the right hand, patterns were increased in the 3rd interdigital area. On the other hand, in female patients there was a significant increase in whorls and decrease in loops on the first finger on both the hands, increase in arches on the 3rd finger; both arches and whorls on the 4th finger of left hand. Present study has emphasized that dermatoglyphics could be applied as a diagnostic tool to patients with rheumatoid arthritis.

    Interstitial lung disease (ILD) is found in up to 30% of patients with rheumatoid arthritis (RA) and is clinically manifest in 5 to 10%, resulting in significant morbidity and mortality. The most frequent histopathological forms are usual interstitial pneumonia and nonspecific interstitial pneumonia. Another recently described presentation is combined pulmonary fibrosis and emphysema. Similarly to idiopathic pulmonary fibrosis, acute exacerbation of ILD may occur in RA and is associated with severe prognosis. Smoking is a known risk factor of RA and may also play a role in the pathogenesis of RA-associated ILD, in combination with genetic and immunologic mechanisms. Several treatments of RA may also lead to drug-induced ILD.

    Glucocorticoids (GCs) were discovered in the 1940s and were administered for the first time to patients with rheumatoid arthritis in 1948. However, side effects were subsequently reported. In the last 7 decades, the mechanisms of action for both therapeutic properties and side effects have been elucidated. Mechanisms for minimizing side effects were also developed. GCs are the most frequently used class of drugs in the treatment of rheumatoid arthritis because of their efficacy in relieving symptoms and their low cost. A review of clinical applications, side effects, and drug interactions is presented. PMID:26611549

    2015-11-01

    The introduction of new biological drugs for the treatment of rheumatoid arthritis and spondyloarthritis has led to the creation of a number of registries in Europe and the United States. Most of them are sponsored by national rheumatology societies, and provide information that is useful in clinical practice concerning the clinical characteristics, efficacy, and safety of all licensed biological drugs. Their findings also help to improve our understanding of the quality of life and working ability of patients receiving biological drugs, and suggest methods for allocating resources. However, there are only a few registries for psoriatic arthritis, and efforts should be made to increase their number to obtain further reliable and useful data.

    The major area of new drug discoveries for the treatment of arthritis is in non-steroidal anti-inflammatory agents (NSAIA). Unfortunately, as yet no new and safe drug of major significance has appeared. Aspirin still ranks high beside the newcomers. Indomethacin, ibuprofen, naproxen, fenoprofen and tolmetin are described and their roles in therapy are discussed. A further group of older drugs receiving new application in the treatment of arthritis is presented. These include penicillamine and the immunosuppressive drugs. Gold and chloroquin are also discussed to put these agents in their proper perspective.

    2016-01-01

    Objective We have shown in vitro and in vivo that osteoclast maturation requires calcium-release activated calcium (CRAC) channels. In inflammatory arthritis, osteoclasts mediate severe and debilitating bone erosion. In the current study, we assess the value of CRAC channels as a therapeutic target to suppress bone erosion in acute inflammatory arthritis. Methods Collagen-induced arthritis (CIA) was induced in mice. The CRAC channel inhibitor 3,4-dichloropropionaniline (DCPA) and a placebo was administered 1 day prior to collagen II booster to induce arthritis. Effects on swelling, inflammatory cell invasion in joints, serum cytokines and bone erosion were measured. Results Assays, by blinded observers, of arthritis severity showed that DCPA, 21 mg/kg/day, suppressed arthritis development over 3 weeks. Bone and cartilage damage in sections of animal feet was reduced approximately 50%; overall swelling of joints was reduced by a similar amount. Effects on bone density by µCT showed clear separation in DCPA-treated CIA animals from CIA without treatment, while differences between controls without CIA and CIA treated with DCPA differed by small amounts and in most cases were not statistically different. Response was not related to anticollagen titres. There were no adverse effects in the treated group on animal weight or activity, consistent with low toxicity. The effect was maximal 12–17 days after collagen booster, during the rapid appearance of arthritis in untreated CIA. At 20 days after treatment (day 40), differences in arthritis score were reduced and tumour necrosis factor α, interleukin (IL)-1, or IL-6 in the serum of the animals were similar in treated and untreated animals. Conclusions DCPA, a novel inhibitor of CRAC channels, suppresses bone erosion associated with acute arthritis in mice and might represent a new treatment modality for acute arthrits. PMID:26819750

    The authors report a case of calcium oxalate arthropathy in a woman undergoing intermittent peritoneal dialysis who was not receiving pharmacologic doses of ascorbic acid. She developed acute arthritis, with calcium oxalate crystals in Heberden's and Bouchard's nodes, a phenomenon previously described in gout. Intermittent peritoneal dialysis may be less efficient than hemodialysis in clearing oxalate, and physicians should now consider calcium oxalate-associated arthritis in patients undergoing peritoneal dialysis who are not receiving large doses of ascorbic acid.

    Individuals with rheumatoid arthritis are at higher risk for infection than the general population, and surgical site infection after spinal surgery in this population can result in clinically significant complications. The goal of this study was to identify risk factors for acute surgical site infection after spinal surgery in patients with rheumatoid arthritis who were treated with nonbiologic (conventional) disease-modifying antirheumatic drugs (DMARDs) alone or with biologic DMARDs. All patients treated with biologic agents were treated with nonbiologic agents as well. The authors performed a retrospective, single-center review of 47 consecutive patients with rheumatoid arthritis who underwent spinal surgery and had follow-up of 3 months or longer. The incidence of surgical site infection was examined, and multivariate logistic regression analysis was performed to test the association of surgical site infection with putative risk factors, including the use of biologic agents, methotrexate, and prednisolone, as well as the duration of rheumatoid arthritis, the presence of diabetes, patient age, length of surgery, and number of operative levels. After spinal surgery, 14.89% (7 of 47) of patients had surgical site infection. Use of methotrexate and/or prednisolone, patient age, diabetes, duration of rheumatoid arthritis, length of surgery, number of operative levels, and use of biologic DMARDs did not significantly increase the risk of infection associated with spinal surgery. All patients who had surgical site infection had undergone spinal surgery with instrumentation. The findings show that greater attention to preventing surgical site infection may be needed in patients with rheumatoid arthritis who undergo spinal surgery with instrumentation. To the authors' knowledge, this is the first study to show that the use of biologic agents did not increase the incidence of surgical site infection after spinal surgery in patients with rheumatoid arthritis

    Tumor necrosis factor-α (TNF-α), a proinflammatory cytokine, plays a key role in the pathogenesis of many inflammatory diseases, including arthritis. Neutralization of this cytokine by anti-TNF-α antibodies has shown its efficacy in rheumatoid arthritis (RA) and is now widely used. Nevertheless, some patients currently treated with anti-TNF-α remain refractory or become nonresponder to these treatments. In this context, there is a need for new or complementary therapeutic strategies. In this study, we investigated in vitro and in vivo anti-inflammatory potentialities of an anti-TNF-α triplex-forming oligonucleotide (TFO), as judged from effects on two rat arthritis models. The inhibitory activity of this TFO on articular cells (synoviocytes and chondrocytes) was verified and compared to that of small interfering RNA (siRNA) in vitro. The use of the anti-TNF-α TFO as a preventive and local treatment in both acute and chronic arthritis models significantly reduced disease development. Furthermore, the TFO efficiently blocked synovitis and cartilage and bone destruction in the joints. The results presented here provide the first evidence that gene targeting by anti-TNF-α TFO modulates arthritis in vivo, thus providing proof-of-concept that it could be used as therapeutic tool for TNF-α-dependent inflammatory disorders.

    2016-01-01

    Reactive arthritis is an acute, aseptic, inflammatory arthropathy following an infectious process but removed from the site of primary infection. It is often attributed to genitourinary and enteric pathogens, such as Chlamydia, Salmonella, Shigella, Campylobacter, and Yersinia, in susceptible individuals. An uncommon and less recognized cause of this disease is preceding colonic infection with Clostridium difficile, an organism associated with pseudomembranous colitis and diarrhea in hospitalized patients and those recently exposed to antibiotics. Recognition of this association may be complicated by non-specific presentation of diarrhea, the interval between gastrointestinal and arthritic symptoms, and the wide differential in mono- and oligoarthritis. We present the case of a 61-year-old, hospitalized patient recently treated for C. difficile colitis who developed sudden, non-traumatic, right knee pain and swelling. Physical examination and radiographs disclosed joint effusion, and sterile aspiration produced cloudy fluid with predominant neutrophils and no growth on cultures. Diagnostic accuracy is enhanced by contemporaneous laboratory investigations excluding other entities such as gout and rheumatoid arthritis and other infections that typically precede reactive arthritis. Contribution of Clostridium infection to reactive arthritis is an obscure association frequently difficult to prove, but this organism is warranted inclusion in the differential of reactive arthritis.

    Seven patients with myasthenia gravis developed clinical signs of arthropathy. In two patients, the symptoms were due to a deforming rheumatoid arthritis and the myasthenic symptoms appeared as a transitory phase during the course of the disease. Muscle antibodies of IgG class were demonstrated with sera from both patients. Autoreactivity between muscle antibodies and rheumatoid factor was detected in one patient. Both patients died from sudden cardiac failure. Necropsy was performed in one and revealed a spotty myocardial necrosis. One patient had juvenile rheumatoid arthritis. Two patients had mild articular symptoms with indices of multivisceral disease and serological findings indicating a systemic lupus erythematous. One patient had classical ankylosing spondylitis, and one, unspecified arthropathy.

    Staphylococcus aureus is one of the most important pathogens in septic arthritis. To analyse the arthritogenic properties of staphylococcal peptidoglycan (PGN), highly purified PGN from S. aureus was intra-articularly injected into murine joints. The results demonstrate that PGN will trigger arthritis in a dose-dependent manner. A single injection of this compound leads to massive infiltration of predominantly macrophages and polymorphonuclear cells with occasional signs of cartilage and/or bone destruction, lasting for at least 14 days. Further studies showed that this condition is mediated by the combined impact of acquired and innate immune systems. Our results indicate that PGN exerts a central role in joint inflammation triggered by S. aureus. PMID:11714392

    The arthritides that meet the definition or reactive arthritis include the so-called seronegative spondyloarthropathies. Patients are usually aged less than thirty-two. Preceding infection is generally intestinal or venereal, although the involved agent may remain unknown. Enteric forms occur in small epidemics, whereas venereal forms correlate with a recent new sexual partner. The clinical picture varies in severity, with manifestations overlapping between disorders, and often the first complaint is extra-articular. Highly suggestive of reactive arthritis is "sausage" deformity of fingers and toes, pain and stiffness about multiple joints accompanied by radiating lower back discomfort, and enthesitis, particularly at the Achilles tendon. One out of six or seven patients becomes disabled; therapy aimed at preventing disability is vital since medication has little effect on spinal involvement. Antibiotic therapy may be effective in cases in which specific etiologic agents are well defined.

    The consequences of inflation and accelerating introduction of automation and microprocessors into industry are a shift from unskilled to skilled work, the lessening of opportunities for the unskilled worker, and growing unemployment. If disabled people are competing for employment they must take every opportunity to extend education and acquire skills. Juvenile chronic arthritis presents one set of problems in vocational rehabilitation at the beginning of a working career and adult rheumatoid arthritis another, commonly in those over 45 years old and previously established in work. The prevalence of severe disability in juvenile chronic arthritis is about 1 in 20 000 of the population, females are affected twice as often as males and 1 in 10 has defective vision or blindness due to chronic iridocyclitis. At school, besides education, there must be emphasis on encouraging independence, self-confidence, mobility and determination. A School Leavers' Conference early in the last year at school gives the adolescent the best chance of choosing a career. Rheumatoid arthritis is three times more common in women and increasingly, over the last 40 years, women are working besides home-making. Morning stiffness, fatigue, immobility and pain are the common symptoms of widespread involvement of joints and systemic disturbance. The principal determinant in the success of vocational rehabilitation is personality, and the social and environmental factors are more significant than the degree of disability. The Disablement Resettlement Officer can assure continuity of rehabilitation between the health and employment services: a favourable outcome is work, self-derived income independence and freedom of movement using whatever technical aids are required to achieve this.

    Aicardi-Goutières syndrome (AGS) is a rare, autosomal recessively inherited, immune-mediated neurodevelopmental disorder. The syndrome causes infantile-onset progressive encephalopathy characterized by the neuroradiologic features of basal ganglia and periventricular white matter calcification, leucodystrophy and cerebral atrophy. Lymphocytosis and elevated levels of interferon alpha (IFN-alpha) in the cerebrospinal fluid are supplementary findings of AGS. It is frequently misdiagnosed as sequelae of congenital infection (pseudo-TORCH) and mostly recognized later. We describe three AGS cases with different clinical presentation, two male siblings with RNASEH2C mutation and a boy with TREX1 mutation. These cases highlight the importance of considering AGS in the differential diagnosis of unexplained leukoencephalopathy and developmental delay. We suggest to search for intracranial calcification, especially if there are more than one affected cases in a family. PMID:27411419

    Chronic inflammatory arthritides in children include a wide range of various diseases. One of the main concerns of physicians who treat these disorders is the risk of permanent physical disability resulting from joint damage. Actual classification relies mainly on clinical features, particularly the number of joints affected at onset, although the general feeling is that chronic childhood arthritis exists in many different entities gathered together under the common names juvenile chronic arthritis or juvenile rheumatoid arthritis. The past 2 years were rather fertile in debates for proposing a progression for more objectivity in nomenclature, which was the theme of the Pediatric Rheumatology Study Group session at the American College of Rheumatology annual meeting held in Atlanta in 1992. The viewpoints from North America and Europe addressed at this meeting were published in a supplement of the Journal of Rheumatology in 1993. A debate on this topic was also organized at the International League Against Rheumatism Congress held in Barcelona in 1993. At present, the main criteria rely on clinical experience and natural history of the diseases and on biology and immunogenetics. Another important concern among pediatric rheumatologists is efficacy of treatment. Questions include, "Are we doing enough?" and "How safe are the therapeutic strategies?" In this review some of the recent studies that may be important for classification and nomenclature and therapy and management are discussed.

    Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by progressive damage of synovial-lined joints and variable extra-articular manifestations. Tendon and bursal involvement are frequent and often clinically dominant in early disease. RA can affect any joint, but it is usually found in metacarpophalangeal, proximal interphalangeal and metatarsophalangeal joints, as well as in the wrists and knee. Articular and periarticular manifestations include joint swelling and tenderness to palpation, with morning stiffness and severe motion impairment in the involved joints. The clinical presentation of RA varies, but an insidious onset of pain with symmetric swelling of small joints is the most frequent finding. RA onset is acute or subacute in about 25% of patients, but its patterns of presentation also include palindromic onset, monoarticular presentation (both slow and acute forms), extra-articular synovitis (tenosynovitis, bursitis), polymyalgic-like onset, and general symptoms (malaise, fatigue, weight loss, fever). The palindromic onset is characterized by recurrent episodes of oligoarthritis with no residual radiologic damage, while the polymyalgic-like onset may be clinically indistinguishable from polymyalgia rheumatica in elderly subjects. RA is characteristically a symmetric erosive disease. Although any joint, including the cricoarytenoid joint, can be affected, the distal interphalangeal, the sacroiliac, and the lumbar spine joints are rarely involved. The clinical features of synovitis are particularly apparent in the morning. Morning stiffness in and around the joints, lasting at least 1 h before maximal improvement is a typical sign of RA. It is a subjective sign and the patient needs to be carefully informed as to the difference between pain and stiffness. Morning stiffness duration is related to disease activity. Hand involvement is the typical early manifestation of rheumatoid arthritis. Synovitis involving the metacarpophalangeal

    Rheumatoid arthritis (RA) is a chronic debilitating autoimmune disorder characterized by synovitis that leads to cartilage and bone erosion by invading fibrovascular tissue. Mouse models of RA recapitulate many features of the human disease. Despite the availability of medicines that are highly effective in many patient populations, autoimmune diseases (including RA) remain an area of active biomedical research, and consequently mouse models of RA are still extensively used for mechanistic studies and validation of therapeutic targets. This review aims to integrate morphologic features with model biology and cover the key characteristics of the most commonly used induced and spontaneous mouse models of RA. Induced models emphasized in this review include collagen-induced arthritis and antibody-induced arthritis. Collagen-induced arthritis is an example of an active immunization strategy, whereas antibody- induced arthritis models, such as collagen antibody-induced arthritis and K/BxN antibody transfer arthritis, represent examples of passive immunization strategies. The coverage of spontaneous models in this review is focused on the TNFΔ (ARE) mouse, in which arthritis results from overexpression of TNF-α, a master proinflammatory cytokine that drives disease in many patients.

    Background Sex medicine studies have shown that there are sex differences with regard to disease characteristics in immune-mediated inflammatory diseases, including psoriasis, in immune response and susceptibility to viral infections. We performed a post hoc analysis of the Observational Study of infectious events in psoriasis complicated by active psoriatic arthritis (SYNERGY) study in patients with psoriatic arthritis (PsA) treated with immunosuppressive regimens including cyclosporine, in order to evaluate potential between-sex differences in severity of disease and prevalence of viral infections. Methods SYNERGY was an observational study conducted in 24 Italian dermatology clinics, which included 238 consecutively enrolled patients with PsA, under treatment with immunosuppressant regimens including cyclosporin A. In this post hoc analysis, patients’ demographical data and clinical characteristics of psoriasis, severity and activity of PsA, prevalence of seropositivity for at least one viral infection, and treatments administered for PsA and infections were compared between sexes. Results A total of 225 patients were evaluated in this post hoc analysis, and 121 (54%) were males. Demographic characteristics and concomitant diseases were comparable between sexes. Statistically significant sex differences were observed at baseline in Psoriasis Area and Severity Index score (higher in males), mean number of painful joints, Bath Ankylosing Spondylitis Disease Activity Index, and the global activity of disease assessed by patients (all higher in females). The percentage of patients with at least one seropositivity detected at baseline, indicative of concomitant or former viral infection, was significantly higher among women than among men. No between-sex differences were detected in other measures, at other time points, and in treatments. Patients developed no hepatitis B virus or hepatitis C virus reactivation during cyclosporine treatment. Conclusion Our post hoc

    Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease characterized by extensive synovitis resulting in erosions of articular cartilage and marginal bone with joint destruction. The lack of immunological tolerance in RA represents the first step toward the development of autoimmunity. Susceptible individuals, under the influence of environmental factors, such as tobacco smoke, and silica exposure, develop autoimmune phenomena that result in the presence of autoantibodies. HLA and non-HLA haplotypes play a major role in determining the development of specific autoantibodies differentiating anti-citrullinated antibodies (ACPA)-positive and negative RA patients. Rheumatoid factor (RF) and ACPA are the serological markers for RA, and during the preclinical immunological phase, autoantibody titers increase with a progressive spread of ACPA antigens repertoire. The presence of ACPA represents an independent risk factor for developing RA in patients with undifferentiated arthritis or arthralgia. Moreover, anti-CarP antibodies have been identified in patients with RA as well as in individuals before the onset of clinical symptoms of RA. Several autoantibodies mainly targeting post-translational modified proteins have been investigated as possible biomarkers to improve the early diagnosis, prognosis and response to therapy in RA patients. Psoriatic arthritis (PsA) is distinguished from RA by infrequent positivity for RF and ACPA, together with other distinctive clinical features. Actually, specific autoantibodies have not been described. Recently, anti-CarP antibodies have been reported in sera from PsA patients with active disease. Further investigations on autoantibodies showing high specificity and sensibility as well as relevant correlation with disease severity, progression, and response to therapy are awaited in inflammatory arthritides.

    Optic neuritis (ON) was rarely reported in juvenile idiopathic arthritis (JIA) patients, particularly in those under anti-tumor necrosis factor alpha blockage. However, to our knowledge, the prevalence of ON in JIA population has not been studied. Therefore, 5,793 patients were followed up at our University Hospital and 630 (11%) had JIA. One patient (0.15%) had ON and was reported herein. A 6-year-old male was diagnosed with extended oligoarticular JIA, and received naproxen and methotrexate subsequently replaced by leflunomide. At 11 years old, he was diagnosed with aseptic meningitis, followed by a partial motor seizure with secondary generalization. Brain magnetic resonance imaging (MRI) and electroencephalogram showed diffuse disorganization of the brain electric activity and leflunomide was suspended. Seven days later, the patient presented acute ocular pain, loss of acuity for color, blurred vision, photophobia, redness and short progressive visual loss in the right eye. A fundoscopic exam detected unilateral papilledema without retinal exudates. Orbital MRI suggested right ON. The anti-aquaporin 4 (anti-AQP4) antibody was negative. Pulse therapy with methylprednisolone was administered for five days, and subsequently with prednisone, he had clinical and laboratory improvement. In conclusion, a low prevalence of ON was observed in our JIA population. The absence of anti-AQP4 antibody and the normal brain MRI do not exclude the possibility of demyelinating disease associated with chronic arthritis. Therefore, rigorous follow up is required.

    Objective To review the literature on the epidemiology of Campylobacter associated ReA. Methods A Medline (PubMed) search identified studies from 1966–2006 that investigated the epidemiology of Campylobacter associated ReA. Search terms included: “reactive arthritis”, “spondyloarthropathy”, “Reiter’s syndrome”, “gastroenteritis”, “diarrhea”, “epidemiology”, “incidence”, “prevalence”, and “Campylobacter”. Results The literature available to date suggests that the incidence of Campylobacter reactive arthritis may occur in 1 to 5% of those infected. The annual incidence of ReA after Campylobacter or Shigella may be 4.3 and 1.3 respectively per 100,000. The duration of acute ReA varies considerably between reports, and the incidence and impact of chronic reactive arthritis from Campylobacter infection is virtually unknown. Conclusions Campylobacter associated ReA incidence and prevalence varies widely from reviews such as: case ascertainment differences, exposure differences, lack of diagnostic criteria for ReA and perhaps genetics and ages of exposed individuals. At the population level it may not be associated with HLA-B27 and inflammatory back involvement is uncommon. Follow up for long-term sequelae is largely unknown. Five percent of Campylobacter ReA may be chronic or relapsing (with respect to musculoskeletal symptoms). PMID:17360026

    Granulocyte-macrophage colony-stimulating factor (GM-CSF) is well-known as a haemopoietic growth factor. However, it is also essential in regulating functions of mature myeloid cells such as macrophages. Preclinical studies and observations of flares of arthritis in patients following GM-CSF treatment supported its important contribution to the pathogenesis of rheumatoid arthritis (RA). As the most advanced compound, mavrilimumab, a monoclonal antibody against GM-CSF receptor, has already completed phase II trials with a long term of follow-up period of 74 weeks. During this exposure period, an acceptable sustained safety and tolerability profile has been observed addressing the concerns of development of cytopenias or pulmonary alveolar proteinosis. Of note, a rapid and sustained efficacy and normalisation of acute phase reactants were consistently shown in studies both targeting GM-CSF and its receptor. Its tumour necrosis factor (TNF) independent mode of action with concurrent blockade of GM-CSF as well as IL-17 signalling reported from preclinical studies supports the assumption that it can be a useful biologic and an alternative agent in TNF inhibitor resistant patients with RA. Therefore, subsequent studies are warranted to investigate the safety and efficacy of GM-CSF blocking agents in different subgroups of RA. PMID:27586802

    Chronic neutrophilic leukemia (CNL) is a rare entity amongst myeloproliferative neoplasms (MPNs). The classical presentation of CNL is with splenomegaly, mature neutrophilic leucocytosis and hyperuricemia. We herein report a case who presented with symptoms of acute gouty arthritis. Physical examination showed typical red, tender tophi in the right hand, right foot and both pinnae suggesting an acute episode of gout. During evaluation, moderate splenomegaly, mature neutrophilia, hyperuricemia and sub-nephrotic range range proteinuria were noted. Bone marrow examination and kidney biopsy was done. Final diagnosis of CNL with acute gouty arthritis and chronic renal thrombotic microangiopathy (TMA) was made. Although hyperuricemia is a common finding in MPNs but presentation of our case with symptoms of acute tophi and chronic TMA is atypical. PMID:27408367

    Septic arthritis in children remains a serious disease with the potential for significant systemic and musculoskeletal morbidity. Staphlococcus aureus is the most common cause of bone and joint infections in all age groups. Microbial invasion of the synovial space occurs typically results from hematogenous seeding. Diagnosis in neonates and young infants can be difficult since the clinical signs are much less specific in these age groups. Early diagnosis by needle aspiration of the affected joint and prompt initiation of appropriate antimicrobial therapy in conjunction with drainage of the affected joint is critical to avoid destruction of the articular cartilage and prevent disability. Septic arthritis in infants and children should always be managed by a pediatrician in close consultation with an orthopedic surgeon. Empiric antibiotic regimens should always include adequate anti-staphylococcal coverage. Antibiotic treatment should be started with appropriate doses of intravenous antibiotics. Switch to oral antibiotic therapy can be made when patient demonstrates clinical improvement. A minimum of 3-4 weeks of therapy is recommended. Close follow-up is warranted to monitor the growth of the affected limb until skeletal maturity.

    Pyogenic knee arthritis caused by group A β-hemolytic Streptococcus (GAS) is rare. GAS sometimes causes group A β-hemolytic streptococcal toxic shock syndrome. We encountered a case of pyogenic knee arthritis caused by GAS that resolved after appropriate treatment (emergency arthroscopic synovectomy and medication) administered within 48 h of onset. In cases of a history of another infection with acute knee joint pain, the possibility of GAS-induced pyogenic knee arthritis should be considered, and proper treatment should be administered immediately.

    Of 400 patients with brucellosis, 104 (26%) had arthritis, of whom 96 could be followed up. The systemic disease in the 96 patients was acute in 54 (56%), subacute in 24 (25%), and chronic in 18 (19%). The main presenting symptoms were joint pain, fever, sweating, and easy fatigability. The joints most commonly affected were the sacroiliac joint (26%) and knee (25%) followed by hip (18%) and spine (8%). There was no particular pattern of joint affection in relation to age. Joint effusion occurred in 32/104 (30%) of cases, predominantly (94%) in the acute group. Culture of synovial fluid was negative in all, and analysis of synovial fluid for cellular profile, glucose, and protein content was not particularly helpful in diagnosis. Plain radiographs did not show major pathological changes. Among the laboratory tests, including haematological and liver function tests, the brucella enzyme linked immunosorbent assay (ELISA) was the most reliable in the diagnosis of disease, using serum and synovial fluid specimens. Treatment with a combination of streptomycin plus tetracyclines or rifampicin resulted in an excellent cure rate and resolution of arthritis without sequelae or mortality. Thus brucellosis should be considered in the differential diagnosis of arthritis, especially in areas in which the disease is endemic. PMID:2270973

    We assessed the effect of a novel and selective phosphodiesterase 4 (PDE4) inhibitor, ciclamilast, on chronic inflammation in adjuvant-induced arthritis (AIA), a rat model of rheumatoid arthritis (RA), and acute inflammation in the rat and mouse model of carrageenan-induced paw edema and peritonitis. Our results showed that daily oral administration of ciclamilast at 1, 3, and 10 mg/kg dose-dependently inhibited the increase in hind paw volume of rats with AIA. The inhibition of paw edema was associated with inhibition of both the production of cytokines such as TNF-α, IL-1β, and IL-6 and cell infiltration assessed in subcutaneous paw tissue. Moreover, there was significantly less tissue destruction in the ciclamilast-treated rats compared to the vehicle-treated rats, as assessed by radiographic analysis and histopathological evaluation. In the two acute inflammation models, ciclamilast inhibited carrageenan-induced paw edema in rats and inflammatory cell migration into the peritoneal cavity in mice in a dose-dependent manner. These results not only suggest that ciclamilast, as a disease-modifying antirheumatic drug (DMARD), can attenuate RA but also provide proof of principle that a PDE4 inhibitor may be useful for the treatment of arthritis.

    To study the occurrence and incidence of different ocular manifestations in rheumatoid arthritis a random cross-sectional study was carried out among 54 patients with active rheumatoid arthritis. The patients were examined thoroughly to detect any ocular disease associated with rheumatoid arthritis. Complete ocular examination with special emphasis on anterior segment evaluation and tearfilm study was done. Two-thirds of the patients examined had some kind of visual problem at presentation. Three patients (5.55%) had marked dry eye with another 20 (37.03%) having borderline tear deficiency. Two cases ( 3.70% ) of episcleritis were also seen. No cases of scleritis or retinopathy were found. The most common ocular association with rheumatoid arthritis was secondary Sjogren's syndrome. Other conditions include episcleritis and marginal keratitis.

    Psoriatic arthritis (PsA) is a heterogeneous condition with a myriad of different clinical presentations. It commonly affects the skin and musculoskeletal system causing psoriasis, peripheral arthritis, axial arthritis, enthesitis and dactylitis. Many patients also have related conditions, such as those within the metabolic syndrome and associated spondyloarthritis (SpA) conditions including inflammatory bowel disease and uveitis. Any therapeutic strategy must be tailored to the individual patient, taking into account her/his complete clinical presentation and comorbidities. New treatment recommendations from the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) provide evidence based recommendations on effective therapies for the management of each different manifestation of PsA, and how treatment may be affected by comorbidities (1). However, the limited evidence comparing different treatment strategies in PsA is recognised as a limitation in these recommendations and further information is detailed below.

    The cytokines are an important substance involved in the immune reaction and maintenance of homeostasis. An imbalance in the cytokine network may lead to inflammation and autoimmune diseases such as rheumatoid arthritis (RA). RA is an autoimmune and systemic inflammatory disorder characterized by synovial inflammation, destruction of cartilage and bone and systemic manifestations. The pro-inflammatory cytokines such as tumor necrosis factor α (TNFα), interleukin-1 (IL-1), IL-6 and IL-17 induce the inflammation of the joints and destruction of bone and cartilage via activation of macrophages, fibroblast like synoviocytes (FLS), helper T (Th) cells and osteoclasts. Recently, the available therapeutic agents that target these cytokines have excellent clinical effects in RA patients.

    Rheumatoid arthritis (RA) is a chronic and painful clinical condition that leads to progressive joint damage, disability, deterioration in quality of life, and shortened life expectancy. Even mild inflammation may result in irreversible damage and permanent disability. The clinical course according to symptoms may be either intermittent or progressive in patients with RA. In most patients, the clinical course is progressive, and structural damage develops in the first 2 years. The aim of RA management is to achieve pain relief and prevent joint damage and functional loss. Physiotherapy and rehabilitation applications significantly augment medical therapy by improving the management of RA and reducing handicaps in daily living for patients with RA. In this review, the application of physiotherapy modalities is examined, including the use of cold/heat applications, electrical stimulation, and hydrotherapy. Rehabilitation treatment techniques for patients with RA such as joint protection strategies, massage, exercise, and patient education are also presented. PMID:15266230

    Septic arthritis is a true rheumatological emergency requiring immediate and thoughtful effort for rapid diagnosis establishment and treatment initiation. Children and elderly persons as well as immunocompromised individuals, patients with pre-existing joint damage and with inflammatory rheumatic joint diseases are preferentially affected. Bacteremia, joint surgery and intra-articular injections pose risk situations for the development of joint infections. The most frequent causative organism is Staphylococcus aureus but other relevant pathogens include coagulase-negative staphylococci, streptococci and mycobacteria. Synovial fluid analysis (e.g. appearance, cell count and microbiological examination) is the most important step to establish the diagnosis. The two main components of therapy consist of joint drainage and antibiotic treatment. The approach to periprosthetic joint infections depends on the duration of symptoms, causative organism and individual factors.

    Juvenile idiopathic arthrithis (JIA) is the most common rheumatic disease of childhood.JIA is a chronic disease that is associated with periods of disease flares and periods of disease inactivity.Early, aggressive treatment with nonsteroidal anti-inflammatory drugs, intra-articular corticosteroid injections, or methotrexate, has significantly improved the outcome of most children who have JIA. Biologics have been shown to be both safe and effective for the treatment of more aggressive forms of arthritis and for uveitis. Long-term safety data of biologics is still uncertain. In the near future, it is hoped that genetic testing will allow earlier diagnosis of JIA as well as help predict the disease course of children who have JIA. Genetic analysis also may allow physicians to target therapies more effectively. It is hoped that development of more specific therapies will decrease overall immunosuppression and other associated toxicities.

    Lyme disease is the most common tick-borne disease in the United States and Europe. Increased awareness of the clinical manifestations of the disease is needed to improve detection and treatment. In the acute and late stages, Lyme disease may be difficult to distinguish from other disease processes. The epidemiology and pathophysiology of Lyme disease are directly related to the Borrelia burgdorferi spirochete and its effects on the integumentary, neurologic, cardiac, and musculoskeletal systems. Lyme arthritis is a common clinical manifestation of Lyme disease and should be considered in the evaluation of patients with monoarticular or pauciarticular joint complaints in a geographic area in which Lyme disease is endemic. Management of Lyme arthritis involves eradication of the spirochete with antibiotics. Generally, the prognosis is excellent. Arthroscopic synovectomy is reserved for refractory cases that do not respond to antibiotics.

    The neuroinflammatory autoimmune disease Aicardi-Goutières syndrome (AGS) develops from mutations in genes encoding several nucleotide-processing proteins, including RNase H2. Defective RNase H2 may induce accumulation of self-nucleic acid species that trigger chronic type I interferon and inflammatory responses, leading to AGS pathology. We created a knock-in mouse model with an RNase H2 AGS mutation in a highly conserved residue of the catalytic subunit, Rnaseh2aG37S/G37S (G37S), to understand disease pathology. G37S homozygotes are perinatal lethal, in contrast to the early embryonic lethality previously reported for Rnaseh2b- or Rnaseh2c-null mice. Importantly, we found that the G37S mutation led to increased expression of interferon-stimulated genes dependent on the cGAS–STING signaling pathway. Ablation of STING in the G37S mice results in partial rescue of the perinatal lethality, with viable mice exhibiting white spotting on their ventral surface. We believe that the G37S knock-in mouse provides an excellent animal model for studying RNASEH2-associated autoimmune diseases. PMID:26880576

    Aicardi-Goutières syndrome (AGS) is a monogenic inflammatory encephalopathy caused by mutations in TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, ADAR1, or MDA5. Mutations in those genes affect normal RNA/DNA intracellular metabolism and detection, triggering an autoimmune response with an increase in cerebral IFN-α production by astrocytes. Microangiopathy and vascular disease also contribute to the neuropathology in AGS. In this study, we report that AGS gene silencing of TREX1, SAMHD1, RNASEH2A, and ADAR1 by short hairpin RNAs in human neural stem cell-derived astrocytes, human primary astrocytes, and brain-derived endothelial cells leads to an antiviral status of these cells compared with nontarget short hairpin RNA-treated cells. We observed a distinct activation of the IFN-stimulated gene signature with a substantial increase in the release of proinflammatory cytokines (IL-6) and chemokines (CXCL10 and CCL5). A differential impact of AGS gene silencing was noted; silencing TREX1 gave rise to the most dramatic in both cell types. Our findings fit well with the observation that patients carrying mutations in TREX1 experience an earlier onset and fatal outcome. We provide in the present study, to our knowledge for the first time, insight into how astrocytic and endothelial activation of antiviral status may differentially lead to cerebral pathology, suggesting a rational link between proinflammatory mediators and disease severity in AGS.

    Aicardi-Goutières syndrome (AGS) is an encephalopathy of early childhood which is most commonly inherited as an autosomal recessive trait. The disorder demonstrates significant genetic heterogeneity with causative mutations in five genes identified to date. Although most patients with AGS experience a severe neonatal or infantile presentation, poor neurodevelopmental outcome and reduced survival, clinical variability in the onset and severity of the condition is being increasingly recognized. A later presentation with a more variable effect on development, morbidity and mortality has been particularly observed in association with mutations in SAMHD1 and RNASEH2B. In contrast, the recurrent c.205C > T (p.R69W) RNASEH2C Asian founder mutation has previously only been identified in children with a severe AGS phenotype. Here, to our knowledge, we present the first report of marked phenotypic variability in siblings both harboring this founder mutation in the homozygous state. In this family, one female child had a severe AGS phenotype with an onset in infancy and profound developmental delay, whilst an older sister was of completely normal intellect with a normal head circumference and was only diagnosed because of the presence of chilblains and a mild hemiplegia. An appreciation of intrafamilial phenotypic expression is important in the counseling of families considering prenatal diagnosis, and may also be relevant to the assessment of efficacy in future clinical trials. In addition, marked phenotypic variation raises the possibility that more mildly affected patients are not currently identified. PMID:23322642

    1987-01-01

    Rat ankle joints injected intraarticularly with 5 micrograms of group A streptococcal peptidoglycan-polysaccharide (PG-APS) developed an acute course of arthritis. Recurrence of arthritis was induced in 100% of these joints by intravenous injection of as little as 10 micrograms of Salmonella typhimurium lipopolysaccharide (LPS) 3 wk after intraarticular injection. This reaction was similar in athymic and euthymic rats. Buffalo rats were less susceptible than Lewis or Sprague- Dawley rats. Neisseria gonorrhoeae, Yersinia enterocolitica, and Escherichia coli LPS, and S. typhimurium Re mutant LPS, were also active. Re mutant LPS activity was greatly reduced by mixing with polymyxin B. E. coli lipid A was weakly active. An acute synovitis of much less incidence, severity, and duration was seen in contralateral joints injected initially with saline, and in ankle joints of naive, previously uninjected rats after intravenous LPS injection. The intravenous injection of the muramidase mutanolysin on day 0 or 7 after intraarticular PG-APS injection prevented LPS-induced recurrence of arthritis. These studies suggest that the phlogistic activities of lipid A and peptidoglycan might interact in an inflammatory disease process, and that LPS may play a role in recurrent episodes of rheumatoid arthritis or reactive arthritis.

  19. [Juvenile idiopathic arthritis: Definition and classification].

    PubMed

    2016-04-01

    Juvenile idiopathic arthritis (JIA) is a group of diseases defined by the presence of arthritis of more than 6 weeks duration in patients aged less than 16 years and with unknown etiology. The international classification based on clinical and biological criteria define each type of JIA: systemic, oligoarticular, polyarticular with and without rheumatoid factor, enthesitis-related arthritis, and psoriatic arthritis. However, some discussions persist concerning systemic-onset juvenile idiopathic arthritis, whose clinical symptoms and pathogenic mechanisms are quite similar to those observed in autoinflammatory diseases, arthritis with antinuclear factors (poly- and oligoarticular) that could be considered as a homogenous group, and a family history of psoriasis that frequently led to unclassified arthritis. Better knowledge of the pathogenic mechanisms should improve the initial clinical classification with more homogeneous groups of patients and reduce the number of unclassified cases of arthritis.

  20. Lyme arthritis in Southern Norway - an endemic area for Lyme Borreliosis

    PubMed Central

    2014-01-01

    Background Despite Southern Norway is an endemic area for Lyme borreliosis there is a lack of data on Lyme arthritis (LA). In the literature controversies exist if acute LA can develop into chronic arthritis. Our objective was to identify and characterize patients with LA in Southern Norway and explore disease course after antibiotic treatment. Methods Patients aged 20 years or older with arthritis and a positive serology for Borrelia burgdorferi infection (IgG and/or IgM) suspected of having LA were consecutively recruited either from general practitioners or from hospital departments. Results From January 2007 to December 2010 a total of 27 patients were assessed. Mean (range) age was 56 years (41–80) and mean symptom duration prior to inclusion was 11.2 weeks (1 day – 2 years). Definite LA was diagnosed in 16 patients, probable LA in 5 patients and 6 patients were concluded to have other arthritis disorders. Among the 21 LA patients 20 had mono-arthritis (knee 18, ankle 2) and 1 had polyarthritis. All LA patients responded favourable to antibiotic treatment and none of the patients developed chronic arthritis after long term follow up, not even in LA patients who had intraarticular glucocorticosteroid (GC) injection prior to antibiotic treatment. Conclusions Our data shows that LA in Southern Norway is a benign disease which successfully can be treated with antibiotics even in patients treated with GC prior to antibiotics. PMID:24708707

    Background Septic arthritis of the temporomandibular (TM) joint is rare, but it is associated with high risk for significant morbidity. Objective We reviewed the available literature regarding the presentation, evaluation, treatment, and clinical course of TM joint septic arthritis, focusing on elements relevant to emergency medicine physicians. Case Reports In the first case, a healthy 6-year-old boy presented with fever and trismus; computed tomography with contrast revealed a TM joint effusion. After empiric intravenous antibiotics, intraoperative arthrocentesis of the TM joint returned one milliliter of flocculent fluid, which was cultured and grew pan-sensitive Streptococcus pyogenes. He was discharge home with amoxicillin/clavulanate and experienced complete resolution of his symptoms. In the second case, more than three weeks after extraction of her third molars, an 18-year-old woman presented with facial pain, swelling, and trismus and was found to have a loculated abscess involving the left masseteric and pterygomandibular spaces with extension to the left deep temporal region and the skull base. She experienced a complicated postoperative course and required multiple procedures and intravenous antibiotics for growth of multiple bacteria. More than a month later underwent TM joint arthrotomy for TM joint septic arthritis, and she was found to have acute osteomyelitis. She continued to require multiple treatment modalities; twenty months after her initial presentation, she underwent left total TM joint arthroplasty for fibrous ankylosis of the TM joint. Conclusion Septic arthritis of the TM joint may be caused by hematogenous spread of distant infection or local spread of deep masticator space infections. Patients may present with TM joint septic arthritis acutely or sub-acutely. Septic arthritis of the TM joint should be considered in the differential diagnosis of patients who present with trismus and pain or fever. PMID:23896057

    Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by synovial inflammation that can lead to structural damage of cartilage, bone and tendons. Assessing the inflammatory activity and the severity is essential in RA to help rheumatologists in adopting proper therapeutic strategies and in evaluating disease outcome and response to treatment. In the last years musculoskeletal (MS) ultrasonography (US) underwent tremendous technological development of equipment with increased sensitivity in detecting a wide set of joint and soft tissues abnormalities. In RA MSUS with the use of Doppler modalities is a useful imaging tool to depict inflammatory abnormalities (i.e. synovitis, tenosynovitis and bursitis) and structural changes (i.e. bone erosions, cartilage damage and tendon lesions). In addition, MSUS has been demonstrated to be able to monitor the response to different therapies in RA to guide local diagnostic and therapeutic procedures such as biopsy, fluid aspirations and injections. Future applications based on the development of new tools may improve the role of MSUS in RA.

    Iliopsoas bursitis is a poorly recognized cause of hip pain that requires early recognition to avoid potentially serious complications caused by compression of adjacent structures. It can occur in the setting of trauma in athletes or those who engage in heavy labor and is also associated with acute or chronic arthritis. We describe the cases of 2 patients, one of whom developed a femoral neuropathy, while the other had marked venous compression of the lower limb resulting from enlargement of the iliopsoas bursa. Magnetic resonance imaging offers the most accurate information on the extent of the problem. Recalcitrant cases may require bursectomy in addition to treatment of the underlying cause.

    Objective To investigate whether the cytokine‐inducing properties of surface‐bound collagen type II (CII)‐containing immune complexes (IC), which were reported earlier, have any clinical impact. Methods Anti‐CII serology was analysed in 274 patients with early rheumatoid arthritis (RA). Patients with increased levels of anti‐CII were followed serially for 1–5 years with regard to anti‐CII IC‐induced levels of tumour necrosis factor (TNF)α, interleukin (IL)1β and IL8. Levels of antibodies and IC‐induced cytokines were compared with clinical indices over 5 years of follow‐up. Results 5/100 healthy controls and 24/274 (8.8%) patients with RA exhibited increased levels (>29 arbitrary units (AU)/ml) of anti‐native CII antibodies, a non‐significant difference. 9/274 (3.3%) patients with RA and no controls comprised a discrete group with high anti‐CII levels >450 AU/ml. These high anti‐CII level sera were associated with induction of pro‐inflammatory cytokines by anti‐CII‐containing IC formed in vitro. 8/9 patients with high baseline anti‐CII levels exhibited a parallel decline in antibody levels, IC‐induced cytokines, C reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Anti‐CII‐positive patients had significantly increased levels of CRP and ESR at baseline, but not later during the follow‐up. Conclusions Anti‐native CII‐positive patients with RA have a distinct clinical phenotype characterised by an early acute phase response that might be driven by anti‐CII‐containing IC in joint cartilage.

    Childhood arthritis has now been reclassified into a single internationally recognized entity of juvenile idiopathic arthritis (JIA). Radiology provides an important role in the management of JIA, in helping in the differential diagnosis, monitoring disease progression and detecting complications. Traditionally, plain radiographs have been the imaging investigation of choice but magnetic resonance imaging (MRI) and ultrasound are now providing a more effective and safer alternative. The appropriate use of sequences in MR imaging is important in the early detection of joint abnormalities in JIA. PMID:11798203

The causative organism, isolated from two separate arthrocenteses, was identified as Capnocytophaga ochracea morphologically and by biochemical reactions. Previous human infections (bacteremias) have occurred in granulocytopenic hosts with concomitant oral pathology including periodontitis and gingivitis. No abnormalities of oral hygiene were present in this patient, and granulocyte numbers were normal or elevated. Eradication of the infection was accomplished with 8 weeks of antibiotic therapy combined with surgical drainage. Septic arthritis expands the spectrum of infections reported to be caused by Capnocytophaga spp. PMID:6715520

The prevalence of temporomandibular joint involvement in published series ranges from 17% to 87%. Temporomandibular joint involvement is difficult to detect clinically, so imaging plays a key role in diagnosis and monitoring treatment. MRI is the technique of choice for the study of arthritis of the temporomandibular joint because it is the most sensitive technique for detecting acute synovitis and bone edema. Power Doppler ultrasonography can also detect active synovitis by showing the hypervascularization of the inflamed synovial membrane, but it cannot identify bone edema. This article describes the MRI technique for evaluating the temporomandibular joint in patients with juvenile idiopathic arthritis, defines the parameters to look for, and illustrates the main findings.

    Rheumatoid arthritis (RA) is an autoimmune systemic disease that primarily affects joints. Etiology and the pathogenesis of RA are complex, involving many types of cells, among others macrophages, T and B cells, fibro- blasts, chondrocytes and dendritic cells. Despite well documented role of many genes and epigenetic modifications in the development and evolution of the disease, in most RA patients there is no clear predisposing factor present. Environmental factors involved in RA pathogenesis are cigarette smoke, industrial pollutants like silica crystals, disturbances of intestinal, lung, and oral microbiota and some specific bacterial and viral infectious agents and their components. In the initial disease stage there are qualitative and quantitative disturbances ofpeptide citrulination as well as other protein modifications, followed by antigen presenting cell (APC) (macrophages and dendritic cells) and fibroblast like synoviocytes (FLS) activation. Some microbes foster this processes by APC and FLS direct and indirect activation. In the second stage APC's elicit specific humoral B cell re- sponse resulting in specific antibodies production and T cell autoreactivity. Inherited and acquired defects in T and B cell responses caused by repeated activation of innate immunity as well as loss of tolerance, elicit chronic autoimmune inflammation, primarily of synovial membranes, and development of cellular panus. Pathologic activation of the osteoclasts and release of the immune system effector molecules and the proteolytic enzymes damage the cartilage, bone and tendons composition and structure. Persistent inflammation through its complex mechanisms results in many systemic and extraarticular RA manifestations of almost all organ systems, resulting in severe complications and comorbidities such as rheumatoid lung, carditis, vasculitis, cahexia, anemia, accelerated atherosclerosis, myocardial and cerebrovascular vascular disease, lymphoma, osteoporosis, depression etc

    Familial juvenile hyperuricaemic (gouty) nephropathy (FJHN), is an autosomal dominant disease associated with a reduced fractional excretion of urate, and progressive renal failure. FJHN is genetically heterogeneous and due to mutations of three genes: uromodulin (UMOD), renin (REN) and hepatocyte nuclear factor-1beta (HNF-1β) on chromosomes 16p12, 1q32.1, and 17q12, respectively. However, UMOD, REN or HNF-1β mutations are found in only approximately 45% of FJHN probands, indicating the involvement of other genetic loci in approximately 55% of probands. To identify other FJHN loci, we performed a single nucleotide polymorphism (SNP)-based genome-wide linkage analysis, in six FJHN families in whom UMOD, HNF-1β and REN mutations had been excluded. Parametric linkage analysis using a 'rare dominant' model established linkage in five of the six FJHN families, with a LOD score >+3, at 0% recombination, between FJHN and SNPs at chromosome 2p22.1-p21. Analysis of individual recombinants in two unrelated affected individuals defined a approximately 5.5 Mbp interval, flanked telomerically by SNP RS372139 and centromerically by RS896986 that contained the locus, designated FJHN3. The interval contains 28 genes, and DNA sequence analysis of the most likely candidate, solute carrier family 8 member 1 (SLC8A1), did not identify any abnormalities in the FJHN3 probands. FJHN3 is likely located within a approximately 5.5 Mbp interval on chromosome 2p22.1-p21, and identifying the genetic abnormality will help to further elucidate mechanisms predisposing to gout and renal failure.

    Rheumatoid arthritis is the most common chronic inflammatory rheumatic disorder, and is characterized by inflammation of the joint, which can lead to irreversible bone damage, joint deformity and disability, if not diagnosed timely or treated adequately. New classification criteria were developed in 2010 in order to identify patients at risk of developing persistent or erosive arthritis, and requiring early therapy. In order to detect early arthritis or bone erosions before their appearance on X-rays, ultrasound and magnetic resonance imaging are now routinely used by clinicians, and also seem to deliver prognostic information about the disease. Synovial biopsies are potentially interesting in case of early arthritis to identify markers of diagnosis, prognosis or therapeutic response. Genetic or environmental risk factors were described to play a role in the development or maintenance of the disease; they could also help to screen early RA. A rapid diagnosis is eventually based on the right information and a tight collaboration between the primary care physician and the rheumatology care specialist. PMID:25675622

    We report the observation of a septic arthritis of the knee complicated within first 36 hours by multiorgan failure including acute respiratory distress syndrome (ARDS), heart failure, acute renal failure and disseminated intravascular coagulation (DIC). A diagnosis of staphylococcal arthritis was suspected confirmed by direct examination, and culture showed a Staphylococcus aureus sensitive to methicillin. The sample sent to the National Reference Centre for Staphylococci (Lyon, France) for genetic analysis confirmed the isolate positive for the PVL gene expression. The fulminating evolution of a septic S. aureus arthritis in an otherwise healthy man should probably evoke the possibility of LPV strain. Anti-PLV antibiotics with anti-staphylococcal activity, such as clindamycin and linezolid should be started without waiting for typing of the S. aureus strain.

    Sixty-one subjects with rheumatoid arthritis, 61 with psoriatic arthritis, 61 with ankylosing spondylitis, and 61 healthy controls were examined with regard to subjective symptoms and clinical signs of craniomandibular disorders (CMD). The frequencies of most subjective and clinical variables were higher in all three disease groups than in the control group. Subjects with rheumatoid arthritis and psoriatic arthritis showed more frequent and severe signs and symptoms than subjects with ankylosing spondylitis. It is concluded that subjective symptoms and clinical signs of CMD are common in rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis and are mainly caused by the respective general joint disease.

    2014-03-01

    Aim of this study was to evaluate the role of synovial interleukin-6 and synovial lactate for predicting native septic arthritis. We analyzed retrospectively synovial fluid parameters (interleukin-6, total-protein, glucose, lactate, synovial-fluid-white-blood-cell-count) of 62 patients with culture-verified native septic arthritis and compared them to 57 patients with acute aseptic arthritis. Receiver-Operating-Characteristic-curves were calculated to determine the 'Area-under-the-curves' (AUC), the best thresholds and the corresponding likelihood-ratios. The best parameter for diagnosing septic arthritis was synovial lactate (AUC = 0.864, sensitivity = 74.5%, specificity = 87.2%), followed by synovial interleukin-6 (AUC = 0.803, sensitivity = 92.5%, specificity = 64.1%) and the synovial-fluid-white-blood-cell-count (AUC = 0.782, sensitivity = 71.2%, specificity = 84.9%). Synovial lactate levels above 10 mmol/l almost proofed septic arthritis (interval-Likelihood-Ratio = 20.4), synovial interleukin-6 levels lower than 7000 pg/ml almost ruled out infection (interval-Likelihood-Ratio = 0.12). If none of these thresholds are met, physicians should estimate disease probability by the simultaneous use of the interval-Likelihood-Ratios of synovial lactate, synovial interleukin-6 and synovial-fluid-white-blood-cell-count.

    This study was carried out to determine an effective regimen for pain management in streptococcal cell wall (SCW)-induced arthritis in female Lew/SSN rats. Forty weanling rats lin 2 groups) were trained to accept disks of jelly as part of their dietary regimen. At 8 weeks of age weighing 150 g, SCW arthritis was induced and sublingual buprenorphine tablets were incorporated into the jelly disks to alleviate the pain of acute arthritis, which developed 24 h post-induction. Group A rats received buprenorphine at a rate of 1 mg/kg 12 hourly. Group B rats received buprenorphine at a rate of 2 mg/kg 12 hourly. Both groups of rats were monitored for symptoms of distress using an adaptation of the Morton and Griffin scale of adverse reactions. Group A rats with severe arthritis required additional subcutaneous (s.c.) injections of buprenorphine to alleviate the adverse effects of arthritis. Group B rats, with twice the dose of buprenorphine did not require additional s.c. injections of buprenorphine. Histological sections of rat hocks indicated that the inflammation was suppressed in Group B rats. We concluded that oral administration of buprenorphine is an effective method of pain management in the pathogenesis of SCW-induced arthritis in Lew/SSN rats. In this model of arthritis, oral buprenorphine has a significant anti-inflammatory effect and appears to modulate the destructive arthritic phase in joints in this animal model of arthritis.

    Septic arthritis is an uncommon condition with an incidence of 2-3/100,000. It is clinically notable, however, as it is a rapidly destructive joint disease with significant associated morbidity and mortality. Polyarticular septic arthritis has an estimated incidence of 15% of all cases of infectious arthritis. We report a case of polyarticular septic arthritis with involvement of bilateral shoulders and wrist to highlight the importance of early diagnosis and treatment as well as the high mortality rates associated with this condition. Bilateral septic shoulder arthritis poses a challenge to treat, and its significance should not be underestimated as even with early surgical intervention and aggressive antibiotic and fluid resuscitation death is a sad but perhaps not uncommon outcome. It is therefore imperative that the diagnosis of polyarticular septic arthritis is kept prominent in the physician's mind when confronted with a patient with symptomatic polyarthralgia.

    Our understanding of psoriatic arthritis has evolved as new knowledge of the disease has emerged. However, the exact prevalence of psoriatic arthritis is unknown, and its pathogenesis has not been fully elucidated. Genetic, environmental, and immunologic factors have all been implicated in disease development. Early diagnosis and treatment have become primary objectives in clinical rheumatology. Psoriatic arthritis not only causes functional impairment, but also increases mortality risk of patients. The advent of new therapeutic agents capable of arresting the progression of joint damage is expected. However, early psoriatic arthritis assessment remains limited. The objectives of this article are to outline the epidemiology, diagnosis, and treatment of psoriatic arthritis and to suggest a paradigm for identifying early psoriatic arthritis patients.

    Psoriatic arthritis (PsA) is a chronic.immune-mediated disease that is observed in 8-30% of psoriatic patients. It has been recently established that PsA and psoriasis are closely associated with the high prevalence of metabolic syndrome, hypertension; abdominal obesity, and a risk for cardiovascular diseases (CVD), including fatal myocardial infarction (Ml) and acute cerebrovascular accidents, which shortens lifespan in the patients compared to the general population. The authors state their belief that the synergic effect of traditional risk factors (RFs) for CYD and systemic inflammation underlie the development of atherosclerosis in PsA. It is pointed out that the risk of CYD may be reduced not only provided that the traditional RFs for CVD are monitored, but also systemic inflammation is validly suppressed. The cardioprotective abilities of methotrexate and tumor necrosis factor-a (TNF-a) inhibitors are considered; the data of investigations showing that the treatment of PsA patients with TNF-a inhibitors results in a reduction in carotid artery intima-media thickness are given. lt is noted that there is a need for the early monitoring of traditional RFs for CVD in patients with PsA and for the elaboration of interdisciplinary national guidelines.

    In the United States, Lyme arthritis is the most common feature of late-stage Borrelia burgdorferi infection, usually beginning months after the initial bite. In some, earlier phases are asymptomatic and arthritis is the presenting manifestation. Patients with Lyme arthritis have intermittent or persistent attacks of joint swelling and pain in 1 or a few large joints. Serologic testing is the mainstay of diagnosis. Synovial fluid polymerase chain reaction for B burgdorferi DNA is often positive before treatment, but is not a reliable marker of spirochetal eradication after therapy. This article reviews the clinical manifestations, diagnosis, and management of Lyme arthritis.

    Management of fungal osteomyelitis and fungal septic arthritis is challenging, especially in the setting of immunodeficiency and conditions that require immunosuppression. Because fungal osteomyelitis and fungal septic arthritis are rare conditions, study of their pathophysiology and treatment has been limited. In the literature, evidence-based treatment is lacking and, historically, outcomes have been poor. The most common offending organisms are Candida and Aspergillus, which are widely distributed in humans and soil. However, some fungal pathogens, such as Histoplasma, Blastomyces, Coccidioides, Cryptococcus, and Sporothrix, have more focal areas of endemicity. Fungal bone and joint infections result from direct inoculation, contiguous infection spread, or hematogenous seeding of organisms. These infections may be difficult to diagnose and eradicate, especially in the setting of total joint arthroplasty. Although there is no clear consensus on treatment, guidelines are available for management of many of these pathogens.

    2014-01-01

    Rheumatoid arthritis (RA) is a complex autoimmune disease affecting 1–2% of general worldwide population. The etiopathogenesis of RA involves the interplay of multiple genetic risk factors and environmental triggers. Microbial infections are believed to play an important role in the initiation and perpetuation of RA. Recent clinical studies have shown the association of microbial infections with RA. Accumulated studies using animal models have also found that microbial infections can induce and/or exaggerate the symptoms of experimental arthritis. In this review, we have identified the most common microbial infections associated with RA in the literature and summarized the current evidence supporting their pathogenic role in RA. We also discussed the potential mechanisms whereby infection may promote the development of RA, such as generation of neo-autoantigens, induction of loss of tolerance by molecular mimicry, and bystander activation of the immune system.

    Juvenile idiopathic arthritis is the most common rheumatic disease in childhood. It is a chronic inflammatory disease associated with arthritis of unknown etiology that begins before the age of 16 and persists for longer than 6 weeks. In this report, the case of a child who suffered recurrent alternative hip arthritis with bilateral hip arthritis is examined, in which he was finally diagnosed as suffering from Juvenile idiopathic arthritis. A 14-year-old boy of Taiwanese origin presented with a normal birth and developmental history. At the age of 10, right-side hip joint pain was experienced, which later migrated to the left side. On further inspection, synovium hypertrophy, cartilage erosion and hip turbid fluid accumulation were found and aseptic arthritis was presumed to be the primary cause. However, after re-examining both his clinical history and presentation, Juvenile idiopathic arthritis was the final diagnosis. Any child presenting with repeat joint swelling are at risk of Juvenile idiopathic arthritis. This is still to be the case if symptoms recede or heal and no initial diagnosis is made. Therefore, a better understanding of the risk of recurrent arthritis is needed. It cannot be emphasized strongly enough that Juvenile idiopathic arthritis should be suspected at all times when a child suffers from recurrent aseptic arthritis of the hip joint.

  17. Arthroscopic Treatment for Primary Septic Arthritis of the Hip in Adults

    2016-01-01

    Purpose. Primary septic arthritis is a rare differential diagnosis of acute hip pain in adults. Inspired by the success of all-arthroscopic treatment in pediatric patients, we developed a diagnostic and surgical pathway for our adult patients. Methods. Seven patients, average age 44 ± 13.7 years with acute hip pain since 4.4 ± 2.9 days in the average, were included. Septic arthritis was confirmed by joint aspiration and dissemination was excluded by MRI and standard radiographs. Surgical treatment consisted of immediate arthroscopic lavage using 4 portals for debridement, high-volume irrigation, partial synovectomy, and drainage. Results. Patients were treated in hospital for 12.4 ± 3.1 days (range 7–16 days). WBC and CRP returned to physiological levels. During the mean follow-up of 26.4 ± 19.4 months (range 13–66 months) no patient showed recurrence of infection. The 5 patients with an unimpaired hip joint prior to the infection had a mean modified Harris Hip Score of 94 ± 5.6 points (range 91–100) at final follow-up. Conclusions. Arthroscopic therapy using a minimally invasive approach with low perioperative morbidity for the treatment of primary septic arthritis of the adult hip is able to restore normal hip function in acute cases without dissemination of the infection.

    Rheumatic diseases, such as rheumatoid and psoriatic arthritis are systemic inflammatory conditions characterized by a chronic form of arthritis, often leading to irreversible joint damage. Early treatment for patients with rheumatic diseases is required to reduce or prevent joint injury. However, early diagnosis can be difficult and currently it is not possible to predict which individual patient will develop progressive erosive disease or who may benefit from a specific treatment according to their clinical features at presentation. Biomarkers are therefore required to enable earlier diagnosis and predict prognosis in both rheumatoid arthritis and psoriatic arthritis. In this review we will examine the evidence and current status of established and experimental biomarkers in rheumatoid and psoriatic arthritis for three important purposes; disease diagnosis, prognosis and prediction of response to therapy.

  3. Photoacoustic tomography to identify inflammatory arthritis

    Identifying neovascularity (angiogenesis) as an early feature of inflammatory arthritis can help in early accurate diagnosis and treatment monitoring of this disease. Photoacoustic tomography (PAT) is a hybrid imaging modality which relies on intrinsic differences in the optical absorption among the tissues being imaged. Since blood has highly absorbing chromophores including both oxygenated and deoxygenated hemoglobin, PAT holds potential in identifying early angiogenesis associated with inflammatory joint diseases. PAT is used to identify changes in the development of inflammatory arthritis in a rat model. Imaging at two different wavelengths, 1064 nm and 532 nm, on rats revealed that there is a significant signal enhancement in the ankle joints of the arthritis affected rats when compared to the normal control group. Histology images obtained from both the normal and the arthritis affected rats correlated well with the PAT findings. Results support the fact that the emerging PAT could become a new tool for clinical management of inflammatory arthritis.

    Carotid artery stenting is an effective treatment for ischemic stroke patients with moderate-to-severe carotid artery stenosis. However, the midterm outcome for patients undergoing this procedure varies considerably with baseline characteristics. To determine the impact of baseline characteristics on outcomes following carotid artery stenting, data from 107 eligible patients with a first episode of ischemic stroke were collected by retrospective chart review. A modified Rankin Scale (mRS) was used to divide patients into two baseline groups, mRS ≤2 and mRS >2. A three-step decision-tree statistical analysis was conducted. After weighting the decision-tree parameters, the following impact hierarchy was obtained: admission low-density lipoprotein, gouty arthritis, chronic kidney disease, ipsilateral common carotid artery resistance index, contralateral ophthalmic artery resistance index, sex, and dyslipidemia. The finite-state machine model demonstrated that, in patients with baseline mRS ≤2, 46% had an improved mRS score at follow-up, whereas 54% had a stable mRS score. In patients with baseline mRS >2, a stable mRS score was observed in 75%, improved score in 23%, and a poorer score in 2%. Admission low-density lipoprotein was the strongest predictive factor influencing poststenting outcome. In addition, our study provides further evidence that carotid artery stenting can be of benefit in first-time ischemic stroke patients with baseline mRS scores >2. PMID:27099508

    Summary Assessing the pathology of the synovium, its thickening and increased vascularity through ultrasound and magnetic resonance examinations (more often an ultrasound study alone) is still considered a sensitive parameter in the diagnosis of rheumatoid arthritis and in monitoring of treatment efficacy. Magnetic resonance studies showed that, aside from the joint pannus, the subchondral bone tissue constitutes an essential element in the development of rheumatoid arthritis. Bone marrow edema correlates with inflammation severity, joint destruction, clinical signs and symptoms of rheumatoid arthritis, and thus is considered a predictor of rapid radiological progression of the disease. The newest studies reveal that bone marrow edema may be a more sensitive indicator of the response to therapy than appearance of the synovium. Bone marrow edema presents with increased signal in T2-weighted images, being most visible in fat saturation or IR sequences (STIR, TIRM). On the other hand, it is hypointense and less evident in T1-weighted images. It becomes enhanced (hyperintense) after contrast administration. Histopathological studies confirmed that it is a result of bone inflammation (osteitis/osteomyelitis), i.e. replacememt of bone marrow fat by inflammatory infiltrates containing macrophages, T lymphocytes, B lymphocytes, plasma cells and osteoclasts. Bone marrow edema appears after a few weeks from occurrence of symptoms and therefore is considered an early marker of inflammation. It correlates with clinical assessment of disease activity and elevated markers of acute inflammatory phase, i.e. ESR and CRP. It is a reversible phenomenon and may become attenuated due to biological treatment. It is considered a “herald” of erosions, as the risk of their formation is 6-fold higher in sites where BME was previously noted PMID:23493495

    Circadian rhythms are driven by biological clocks and are endogenous in origin. Therefore, circadian changes in the metabolism or secretion of endogenous glucocorticoids are certainly responsible in part for the time-dependent changes observed in the inflammatory response and arthritis. More recently, melatonin (MLT), another circadian hormone that is the secretory product of the pineal gland, has been found implicated in the time-dependent inflammatory reaction with effects opposite those of cortisol. Interestingly, cortisol and MLT show an opposite response to the light. The light conditions in the early morning have a strong impact on the morning cortisol peak, whereas MLT is synthesized in a strictly nocturnal pattern. Recently, a diurnal rhythmicity in healthy humans between cellular (Th1 type) or humoral (Th2 type) immune responses has been found and related to immunomodulatory actions of cortisol and MLT. The interferon (IFN)-gamma/interleukin (IL)-10 ratio peaked during the early morning and correlated negatively with plasma cortisol and positively with plasma MLT. Accordingly, the intensity of the arthritic pain varies consistently as a function of the hour of the day: pain is greater after waking up in the morning than in the afternoon or evening. The reduced cortisol and adrenal androgen secretion, observed during testing in rheumatoid arthritis (RA) patients not treated with glucocoticoids, should be clearly considered as a "relative adrenal insufficiency" in the presence of a sustained inflammatory process, and allows Th1 type cytokines to be produced in higher amounts during the late night. In conclusion, the right timing (early morning) for the glucocorticoid therapy in arthritis is fundamental and well justified by the circadian rhythms of the inflammatory mechanisms. PMID:16855156

    Cardiovascular diseases (CVD) are serious complications in patients with rheumatoid arthritis (RA) in its high morbidity and mortality. The risk of coronary artery disease (CAD)has been reported to relate to RA disease activity. By improvement of treatment agents and treatment strategy aiming remission or low disease activity of RA, the incidence of CAD can be decreasing. The cardiovascular morbidity may be attributed to other types of CVD such as large vessel diseases, microvascular myocardial dysfunction or arrhythmia in addition to CAD. To improve quality of life and mortality of RA patients, physicians should treat patients to prevent cardiovascular morbidity through RA disease control. PMID:27311194

    Although the use of corticosteroids in juvenile idiopathic arthritis (JIA) is now much more limited owing to the availability of methotrexate and biological agents, there are clinical scenarios where it is still indicated. For example, corticosteroids may be indicated for intraarticular injections to prevent joint deformities, as a "bridge" drug to relieve symptoms in polyarticular disease while waiting for methotrexate and biologics to exert their full therapeutic effects, and in the treatment of chronic iridocyclitis, macrophage activation syndrome, and systemic JIA, although the advent of interleukin (IL)-1 and IL-6 blockers has greatly reduced the latter indication.

Interstitial lung disease (ILD) and airways disease are the most common forms of RA-related lung disease. RA-ILD carries the worst prognosis and most often manifests in a histologic pattern of usual interstitial pneumonia or nonspecific interstitial pneumonia. There have been no large, well-controlled prospective studies investigating therapies for RA-ILD. Treatment usually entails immunomodulatory agents. Further studies are needed to better understand pathogenic mechanisms of disease that lead to lung involvement in these patients.

    Biologic medications, therapeutic proteins that inhibit or modulate proinflammatory immune cells and cytokines, have significantly altered clinicians' ability to effectively treat psoriatic arthritis (PsA). The first widely used biologics have been those targeting tumor necrosis factor alpha. Five agents (etanercept, infliximab, adalimumab, golimumab, and certolizumab) have shown significant benefit in all clinical domains of PsA as well as inhibiting progressive joint destruction. Treatment strategies such as treating PsA early in the disease course, treating to target and tight control, use of background methotrexate to reduce immunogenicity, and various cost-saving strategies are all being tested with biologic medicines for PsA.

    2015-02-01

    Septic arthritis of the pubic symphysis is a rare infection mostly caused by Staphylococcus aureus, and is traditionally associated with risk factors (sports, female incontinence surgery). Typical features of pubic symphysis infection include abdominal, pelvic, or groin pain that increases upon standing and walking, causing limping to occur. Acute onset of fever is often associated. It is important to distinguish septic arthritis of the pubic symphysis from its aseptic homologue, improperly called 'osteitis pubis' in English literature. This general term is mostly used to designate a mechanical pubic pain and has several aetiological meanings (joint stress, postoperative pain, rheumatic diseases). However, some authors consider the infection of the pubic symphysis as a variant of osteitis pubis, placing the two diseases in the continuum of the same entity. This confusion in pubic pathology related to its rarity and its atypical presentation, may in some cases lead to diagnostic and therapeutic delay. In this article, we would like to make practitioners aware of this uncommon and often ignored anatomical site, so that it can recover its place in the differential diagnosis of abdominal pain.

    Conflict of interest: none declared. Aim Rheumatoid arthritis is considered a clinical syndrome across several disease subsets characterized by systemic inflammation, persistent synovitis, and autoantibodies. Our aim was to assess the distribution of risk factors among people diagnosed with rheumatoid arthritis in the adult population of Tirana, the capital city of Albania. Methods All individuals diagnosed with rheumatoid arthritis in primary health care services of Tirana city during the period 2009-2012 were included in this study. The diagnosis of rheumatoid arthritis was based on the clinical signs and symptoms and laboratory tests including measurement of the rheumatoid factor. Results Overall, there were identified 817 cases with rheumatoid arthritis in all primary health care centers of Tirana for the period 2009-2012. Of these, 529 (65%) were women and 288 (35%) were men. Genetic factors accounted for 60% of the diseases in women and 45% in men (P<0.001). In both sexes, the proportion of older individuals was higher compared with younger adults. Most of the individuals with rheumatoid were from urban areas of Tirana. Conclusion Our study provides new evidence about the distribution of risk factors of rheumatoid arthritis in transitional Albania where valid and reliable data about this disease were scarce. Future studies in Albania should assess the prevalence of rheumatoid arthritis in population-based samples. PMID:24082831

    Rheumatoid arthritis is the most commonly diagnosed systemic inflammatory arthritis. Women, smokers, and those with a family history of the disease are most often affected. Criteria for diagnosis include having at least one joint with definite swelling that is not explained by another disease. The likelihood of a rheumatoid arthritis diagnosis increases with the number of small joints involved. In a patient with inflammatory arthritis, the presence of a rheumatoid factor or anti-citrullinated protein antibody, or elevated C-reactive protein level or erythrocyte sedimentation rate suggests a diagnosis of rheumatoid arthritis. Initial laboratory evaluation should also include complete blood count with differential and assessment of renal and hepatic function. Patients taking biologic agents should be tested for hepatitis B, hepatitis C, and tuberculosis. Earlier diagnosis of rheumatoid arthritis allows for earlier treatment with disease-modifying antirheumatic agents. Combinations of medications are often used to control the disease. Methotrexate is typically the first-line drug for rheumatoid arthritis. Biologic agents, such as tumor necrosis factor inhibitors, are generally considered second-line agents or can be added for dual therapy. The goals of treatment include minimization of joint pain and swelling, prevention of radiographic damage and visible deformity, and continuation of work and personal activities. Joint replacement is indicated for patients with severe joint damage whose symptoms are poorly controlled by medical management.

    Staphylococcus aureus is the most common bacterial species found in nongonococcal bacterial arthritis in humans. We present the first description, to our knowledge, of an outbreak of spontaneous staphylococcal arthritis in a rat colony. In a group of 10 rats, 9 displayed arthritis. Clinically, the most obvious findings were arthritis of one or both hindpaws and malaise. Bacteriophage typing showed the common phage type 85 in isolates recovered from the joints, blood, and bedding of rats and from the nose and cheeks of one person from the staff of the animal facility. The S. aureus strain proved to produce staphylococcal enterotoxin A and exhibited strong binding to collagen types I and II and bone sialoprotein, which are potentially important virulence factors. When the recovered S. aureus strain was injected intravenously into healthy rats, severe septic arthritis was induced in almost all of the animals. The arthritic lesions were characterized by infiltration of phagocytic cells and T lymphocytes into the synovium. Many of the synovial cells strongly expressed major histocompatibility complex class II molecules. Increased levels of interleukin 6 in serum as well as a prominent polyclonal B-cell activation were noted throughout the disease course. Pretreatment of S. aureus-injected rats in vivo with an antibody to the alpha beta T-cell receptor significantly decreased the severity of the arthritis. Our results indicate that alpha beta + T lymphocytes contribute to an erosive and persistent course of S. aureus arthritis. Images PMID:8188356

    Inflammatory arthritis (e.g. rheumatoid arthritis; RA) is a complex disease driven by the interplay of multiple cellular lineages. Fullerene derivatives have previously been shown to have anti-inflammatory capabilities mediated, in part, by their ability to prevent inflammatory mediator release by mast cells (MC). Recognizing that MC can serve as a cellular link between autoantibodies, soluble mediators, and other effector populations in inflammatory arthritis, it was hypothesized that fullerene derivatives might be used to target this inflammatory disease. A panel of fullerene derivatives was tested for their ability to affect the function of human skin-derived MC as well as other lineages implicated in arthritis, synovial fibroblasts and osteoclasts. It is shown that certain fullerene derivatives blocked FcγR- and TNF-α-induced mediator release from MC; TNF-α-induced mediator release from RA synovial fibroblasts; and maturation of human osteoclasts. MC inhibition by fullerene derivatives was mediated through the reduction of mitochondrial membrane potential and FcγR-mediated increases in cellular reactive oxygen species and NF-κB activation. Based on these in vitro data, two fullerene derivatives (ALM and TGA) were selected for in vivo studies using K/BxN serum transfer arthritis in C57BL/6 mice and collagen-induced arthritis (CIA) in DBA/1 mice. Dye-conjugated fullerenes confirmed localization to affected joints in arthritic animals but not in healthy controls. In the K/BxN moldel, fullerenes attenuated arthritis, an effect accompanied by reduced histologic inflammation, cartilage/bone erosion, and serum levels of TNF-α. Fullerenes remained capable of attenuating K/BxN arthritis in mast cell-deficient mice Cre-Master mice, suggesting that lineages beyond the MC represent relevant targets in this system. These studies suggest that fullerene derivatives may hold promise both as an assessment tool and as anti-inflammatory therapy of arthritis.

    Over the past 10 years, the management of rheumatoid arthritis has been revolutionized. Early diagnosis is essential and should allow an early initiation of disease modifying anti-rheumatic drugs (DMARD), if possible within the first 3 three months after disease onset, aiming at disease remission and the best long-term prognosis. Recommendations for the prescription of synthetic and biologic DMARD (mainly anti-TNFalpha agents) are available since September 2007 [6] by HAS in France. The great efficacy of these drugs has been established from many clinical trials including tens of thousands of patients. However, severe adverse side effects may occur (allergy, tuberculosis, opportunistic infections, demyelination) and rheumatologists should remain vigilant. Global care of the patient includes prescription of pharmacologic and non-pharmacologic treatments (education, physical treatment, ergotherapy, psychotherapy, surgery). A good coordination between all specialists is required. Screening and treatment of extra-articular manifestations, prevention of infections, osteoporosis and cardiovascular complications are essential to allow a better long-term prognosis, and reduce disability and mortality of rheumatoid arthritis.

    A case of Lyme arthritis with advanced degenerative changes localized to the midcarpal joint was treated with a limited wrist arthrodesis with relief of pain and improved function. Chronic Lyme arthritis occurs as the third stage of Lyme disease. Serologic testing and a history of a characteristic rash may be helpful in the diagnosis. Radiographic and histopathologic findings are nonspecific, with both degenerative and inflammatory characteristics. Intravenous antibiotics provide an effective treatment of chronic Lyme arthritis.

    Rheumatoid arthritis (RA) is a systemic inflammatory disease affecting primarily the joints but also other organs including skin. Panniculitis is an extremely rare manifestation of the disease manifesting mainly as reddish, ulcerative painful nodules and papules, usually in the legs. Histopathologically, it is characterised by liponecrobiosis, granulocytic and histiocytic infiltrates and vasculopathy. Herein, we describe a middle-aged woman with past medical history of hypertension and diabetes mellitus, and unremarkable family history, who presented with symmetrical polyarthritis, low grade fever and painful subcutaneous nodules in the abdomen. Her laboratory tests showed high acute phase reactants, positive rheumatoid factor and anti-Ro autoantibodies and negative anti-CCP. Surgical resection and histological examination of the nodules revealed neutrophilic lobular panniculitis associated with RA. She was treated with low doses of glucocorticosteroids and methotrexate. The latter was substituted with leflunomide due to toxicity. The patient had significant clinical and laboratory improvement.

    The past decade has brought important advances in the understanding of rheumatoid arthritis and its management and treatment. New classification criteria for rheumatoid arthritis, better definitions of treatment outcome and remission, and the introduction of biologic response-modifying drugs designed to inhibit the inflammatory process have greatly altered the approach to managing this disease. More aggressive management of rheumatoid arthritis early after diagnosis and throughout the course of the disease has resulted in improvement in patient functioning and quality of life, reduction in comorbid conditions, and enhanced survival.

  6. Evidence of Chlamydia trachomatis infection in sexually acquired reactive arthritis.

    1980-10-01

    Thirty male patients with sexually acquired reactive arthritis (SARA) have been studied at the time of their initial presentation and thereafter. Chlamydia trachomatis was isolated from the urethral exudate of 9 (36.0%) of the 25 patients from whom urethral specimens were taken, and elevated titres of IgM antibody of C. trachomatis were detected in 11 (36.6%) of the 30 initial sera. Thirteen (43.3%) of the patients has a positive urethral culture and/or elevated titre of IgM antibody, and it is therefore suggested that 43.3% of these patients suffered an acute chlamydial infection at or near the time of the onset of their joint disease. The demonstration of 4-fold or greater rises and/or falls in IgM antibody titre (8 patients) and IgG antibody titre (6 patients) in a group of 15 men studied throughout the course of their disease strongly supports this conclusion. A positive urethral culture and/or raised titre of IgM serum antibody was also detected in 25 (50%) of 50 men with uncomplicated nongonococcal urethritis (NGU), suggesting that the prevalence of chlamydial infections in the 2 conditions is similar. Titres of IgG serum antibody to C. trachomatis were, however, significantly higher in patients with SARA than in those with NGU or other rheumatic diseases, and in healthy controls. The geometric mean titres (GMT) of IgG serum antibody in patients with SARA, NGU, rheumatoid arthritis, ankylosing spondylitis, systemic lupus erythematosus, and in healthy controls were 1:47.5, 1:8.6, 1:2.2, 1;2.2, 1:3.5, and 1:1.4, respectively. These findings suggest that an exaggerated antibody response to acute infection by C. trachomatis may be an important factor in the development of SARA in some but not all patients.

    Interleukin (IL)-6 has a variety of biological functions. For example, it stimulates the production of acute-phase reactants (C-reactive protein and serum amyloid A) and hepcidin which interferes with iron recycling and absorption, causing iron-deficient anemia, and augments expression of vascular endothelial growth factor and receptor activator of nuclear factor-κB ligand in synovial cells, leading to neovascularization and osteoclast formation. IL-6 also acts on lymphocytes, not only on B cells to stimulate autoantibody production, but also on naïve T helper cells to promote Th17 cell differentiation. Thus, an imbalance between T cell subsets possibly contributes to development of rheumatoid arthritis. Several clinical studies have demonstrated that a humanized anti-IL-6 receptor antibody, tocilizumab, improves clinical symptoms in rheumatoid arthritis. Tocilizumab prevented radiographic progression of joint destruction by inhibiting cartilage/bone resorption. Tocilizumab also improved hematological abnormalities, including hypergammaglobulinemia, high levels of autoantibodies, and elevation of erythrocyte sedimentation rate and acute-phase proteins. Importantly, tocilizumab improved quality of life by reducing systemic symptoms, including fatigue, anemia, anorexia, and fever. These findings have confirmed that hyperproduction of IL-6 is responsible for the above clinical symptoms, including joint destruction. Many patients treated with tocilizumab achieved clinical remission associated with decreased serum IL-6, suggesting that IL-6 enhances autoimmunity. Tocilizumab is a new therapeutic option for rheumatoid arthritis.

    OBJECTIVE—To determine whether the humoral anti-chlamydia antibody response might be related to the ineffective bacterial elimination seen in patients with Chlamydia trachomatis reactive arthritis, particularly in men, who have a higher prevalence of the disease than women.
METHODS—The number and specificity of the antibody responses to 27 different C trachomatis antigens were determined by western blots in serum samples from patients with C trachomatis urogenital infection, with and without reactive arthritis, with a special regard to the sex of the patients.
RESULTS—Patients with reactive arthritis had antibodies to significantly fewer chlamydia antigens than those with urethritis only. Antibodies from men recognised significantly fewer antigens than antibodies from women. The IgA class antibodies were slightly more relevant than those of the IgG class for differentiation of patients with reactive arthritis from those with uncomplicated genitourinary infection.
CONCLUSIONS—In patients with acute C trachomatis infection the development of reactive arthritis may be related, particularly in men, to a deficient humoral response, to antigens which perhaps play a part in the clearance of the bacteria. Men who cannot generate antibodies to a large number of antigens may be less able to contain the local infection, allowing a wide systemic dissemination of the organisms to the joints.

    Little information is available about several important aspects of the treatment of melioidosis osteomyelitis and septic arthritis. We undertook a retrospective review of 50 patients with these conditions in an attempt to determine the effect of location of the disease, type of surgical intervention and duration of antibiotic treatment on outcome, particularly complications and relapse. We found that there was a 27.5% risk of osteomyelitis of the adjacent bone in patients with septic arthritis in the lower limb. Patients with septic arthritis and osteomyelitis of an adjacent bone were in hospital significantly longer (p = 0.001), needed more operations (p = 0.031) and had a significantly higher rate of complications and re-presentation (p = 0.048). More than half the patients (61%), most particularly those with multifocal bone and joint involvement, and those with septic arthritis and osteomyelitis of an adjacent bone who were treated operatively, needed more visits to theatre.

    Synovial fluid, ultrasound, and radiographic imaging are common diagnostic tools for septic arthritis. Mycoplasma septic arthritis is suspected in calves with clinical signs of otitis and pneumonia. Commonly affected joints are carpus, stifle, and tarsus. Treatment strategy must include long-term antibiotics, anti-inflammatories, and joint lavage. Knowledge of communication and boundaries for commonly affected joints is essential to perform joint lavage and arthrotomy.

    Although rheumatoid arthritis (RA) is the most common chronic inflammatory autoimmune disease, diagnosis of RA is currently based on clinical manifestations, and there is no simple, practical assessment tool in the clinical field to assess disease activity and severity. Recently, there has been increasing interest in the discovery of new diagnostic RA biomarkers that can assist in evaluating disease activity, severity, and treatment response. Proteomics, the large-scale study of the proteome, has emerged as a powerful technique for protein identification and characterization. For the past 10 years, proteomic techniques have been applied to different biological samples (synovial tissue/fluid, blood, and urine) from RA patients and experimental animal models. In this review, we summarize the current state of the application of proteomics in RA and its importance in identifying biomarkers and treatment targets. PMID:26330803

    Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease characterized by inflammation of the synovial membrane and progressive destruction of the articular cartilage and bone. Advances in the knowledge of disease pathogenesis allowed the identification of novel therapeutic targets such as tumor necrosis factor (TNF), interleukin (IL)-1, IL-6 or the system JAK/STAT phosphorylation. At present there are 5 TNF antagonists approved for RA. Tocilizumab blocks the pathway of IL-6 and is the only biological with proven efficacy in monotherapy. Rituximab modulates B cell response in RA. Abatacept provided new data on T cell involvement in the pathogenesis of RA. Tofacitinib is the first kinase inhibitor approved for this disease. Biologic drugs have proven efficacy, almost always in combination with methotrexate, and even halt radiographic progression. Monitoring infection is the main precaution in handling these patients.

    The prevalence and mechanisms of hypercalcaemia were studied in a series of patients attending a regional referral centre for rheumatic diseases. In a prospective study one case of hypercalcaemia due to primary hyperparathyroidism was found in 251 consecutive patients who were screened over a three month period. In a retrospective study of 39 patients who had been discovered to be hypercalcaemic during the preceding 12 months known cases of hypercalcaemia were found in 38 (97%) cases. Primary hyperparathyroidism was the most common cause (n = 24; 62%), followed by thiazide treatment in five (13%), cancer in three (8%), immobility in three (8%), vitamin D toxicity in two (5%), and chronic liver disease in one (3%). In one case the diagnosis remained unclear after full investigation. This study shows that the causes of hypercalcaemia in rheumatological patients are similar to those in the general population. These observations contrast with previous reports, which suggested that hypercalcaemia may be a complication of rheumatoid arthritis itself. PMID:2310223

    The main objectives of team management of rheumatoid arthritis are to stop structural damage of joints and to reduce functional, psychological, socioprofessional and economic consequences. Team management requires the collaboration, around the patient, of a rheumatologist, a nurse, a psychologist, a physiotherapist, an occupational therapist, an orthopaedic surgeon at the same time, in the same place. More and more patients wish to manage their disease by themselves. Team care should not be proposed to every patient; it must be reserved to patients whose condition required such an approach because of the severity of the disease, comorbidity, psychological or socioprofessionnal difficulties. Team management should be personalized. Utility of team management is now accepted; out-patient administration is as effective as in-patient one. A good educational program is very important. However, search is still needed to define optimal modalities of team management and tools to measure the efficiency of this approach.

    The primary objective of this investigation was to assess the relationships between clinical characteristics, lung involvement, and frequency of pulmonary involvement in rheumatoid arthritis (RA). Using high-resolution computed tomography (HRCT) and pulmonary function tests (PFT), we prospectively evaluated 52 patients with RA (eight males and 44 females, mean age 53.6 years). The HRCT was abnormal in 35 patients (67.3%), the most frequent abnormalities being reticulonodular patterns, which were found in 22 patients (62.9%), ground-glass attenuation (20%), and bronchiectasis (17%). In this group of patients, PFT results were normal in 13 patients (37%). Titers of rheumatoid factor and erythrocyte sedimentation rate were significantly higher in abnormal HRCT presence. Higher Larsen's score, advanced age, and severe disease were significant risk factors for lung involvement (p<0.001, p<0.01, and p<0.01, respectively) and are suggested by our data to be statistically significant predictors of lung involvement in RA.

    Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by destructive cartilages, bones and other structures formed joints. RA belongs to connective tissue diseases represented by systemic nature, internal illness, extra-articular features and rapidly progress of atherosceirosis. The extra-articular complications cause the reduction of patient longevity. The frequency of symptoms in patient with RA and respiratory disorders occur in 10-20% of cases. Pulmonary complications are the second most common cause of premature of patient deaths. Respiratory disorders associated with RA are devided into 3 groups: infection, lung disease caused by drugs and pulmonary manifestation connected by RA. These last affect interstitial tissue, bronchioli, pulmonary vessels, pleura, also are presented by pulmonary rheumatoid nodules and pulmonary hypertension.

    Psoriasis is an immune-mediated skin disease which affects 2-4% of the worldwide population. Approximately 20-30% of patients with psoriasis develop psoriatic arthritis (PsA), a frequently destructive and disabling condition. As skin manifestations precede joint symptoms in nearly all patients with PsA, identification of biomarkers for early prediction of joint damage is an important clinical need. Because not all patients with PsA respond to treatment in the same fashion, identification of biomarkers capable of predicting therapeutic response is also imperative. Here, we review existing literature and discuss current investigations to identify potential biomarkers for PsA disease activity, with particular emphasis on microRNAs as novel markers of interest. Serum (soluble) biomarkers, peripheral osteoclast precursor as cellular biomarkers, and genetic loci associated with skin and joint disease are also reviewed. PMID:26602058

    The status of rheumatoid arthritis (RA) in Saudi Arabia (SA) was examined from various perspectives based on a systematic literature review and the authors’ personal experiences. In this regard, database and journal search were conducted to identify studies on RA in SA, yielding a total of 43 articles. Although efforts have been made to promote RA research in SA, current studies mostly represent only a few centers and may not accurately portray the national status of RA care. Notably, biological therapies were introduced early for almost all practicing rheumatologists in SA (government and private). However, no national guidelines regarding the management of RA have been developed based on local needs and regulations. Also, while efforts were made to establish RA data registries, they have not been successful. Taken together, this analysis can contribute to the planning of future guidelines and directives for RA care in SA. PMID:25491208

    Radiologic assessment of the stage and treatment response of rheumatoid arthritis (RA) is based on the presence of bone erosions, joint-space narrowing, and osteoporosis. Most radiologic methods for staging RA lack interobserver correlation and are time consuming. Magnetic resonance (MR) imaging provides excellent depiction of soft-tissue abnormalities of the joints affected by RA, which allows detection of early changes. Nineteen joints of 17 patients with RA were studied with surface-coil MR imaging. Measurable abnormalities demonstrated by MR imaging but not clearly seen on plain radiographs included bone erosions, joint effusion, synovial sheath effusion, and cartilage irregularity and thinning. Seven patients of this group underwent MR imaging before and after 6 months of gold therapy. Four patients had significant interval changes on MR images that were not seen on plain radiographs. MR imaging may become a sensitive and objective method for quantitative assessment of the joint changes of RA. PMID:3628762

    Control of disease activity and recovery of function are major issues in the treatment of children and adolescents suffering from juvenile idiopathic arthritis (JIA). Functional therapies including physiotherapy are important components in the multidisciplinary teamwork and each phase of the disease requires different strategies. While in the active phase of the disease pain alleviation is the main focus, the inactive phase requires strategies for improving motility and function. During remission the aim is to regain general fitness by sports activities. These phase adapted strategies must be individually designed and usually require a combination of different measures including physiotherapy, occupational therapy, massage as well as other physical procedures and sport therapy. There are only few controlled studies investigating the effectiveness of physical therapies in JIA and many strategies are derived from long-standing experience. New results from physiology and sport sciences have contributed to the development in recent years. This report summarizes the basics and main strategies of physical therapy in JIA.

  7. Videoradiographic analysis of the range of motion in unilateral experimental knee joint arthritis in rats

    PubMed Central

    2011-01-01

    Introduction The translational and predictive value of animal models highly depends on the validity of respective readout parameters. In arthritis research, there has been a shift from sole threshold testing for pain-related behavior, as well as from swelling and histology assessment for inflammation, toward an analysis of joint function as indicated, for instance, by an increasing number of studies on gait abnormalities. Clinically, the range of motion (ROM) of the affected joint plays a major role in diagnosis and the assessment of treatment benefits. This parameter, however, is only insufficiently detected by currently used analytic systems in animals. Methods Here we used high-resolution videoradiographic analysis to assess ROM in experimental knee joint arthritis in rats. This parameter is described during the 21-day course of antigen-induced arthritis in rats. Furthermore, the therapeutic effects of antinociceptive (morphine) and anti-inflammatory (dexamethasone) treatment on ROM are documented. To obtain additional information on the implications of ROM in animal models, correlations were performed to measure pain-related behavior and inflammation. Results The study animals showed a significant reduction in ROM of the inflamed knee joint in the acute phase of arthritis. This was accompanied by an increase in knee joint movement on the contralateral side, indicating a compensational mechanism. Both morphine and dexamethasone treatment increased and thus normalized ROM. Changes in ROM were further stage-dependently correlated with weight bearing and joint swelling, that is, with both pain-related behavior and signs of inflammation. Conclusions The dynamic ROM observed in freely moving rats in our model of knee joint arthritis might serve as a parameter for global disease activity and might thus represent a promising readout parameter for preclinical assessment regarding the overall efficacy not only of antiarthritic but also of antinociceptive compounds.

    The majority of patients with gout are cared for by primary care physicians. Although both the physician and patient may easily recognize the acute arthritis of gout, errors in selecting the most appropriate medication and proper dose are common. The clinical stages of gout include asymptomatic hyperuricemia, intermittent gouty arthritis, and chronic tophaceous gout. Treatment of gout is usually considered after the first attack of arthritis, typically podagra. The aims of treatment are to alleviate the pain and inflammation associated with acute attacks, prevent future attacks, and decrease uric acid levels. Confusion frequently arises because certain medications such as colchicine may have dual purposes: to treat an acute attack and to suppress future attacks.

    PubMed

    Chikanza, Ian C

    2002-01-01

    Juvenile rheumatoid arthritis (JRA) is the most common childhood chronic systemic autoimmune inflammatory disease. The therapeutic approach to JRA has, to date, been casual and based on extensions of clinical experiences gained in the management of adult rheumatoid arthritis (RA). The physiology of inflammation has been systemically studied and this has led to the identification of specific therapeutic targets and the development of novel approaches to the management of JRA. The classical treatments of the disease such as methotrexate, sodium aurothiomalate and sulfasalazine, are not always effective in controlling RA and JRA. This has necessitated the development of novel agents for treating RA, most of which are biological in nature and are targeted at specific sites of the inflammatory cascades. These biological therapeutic strategies in RA have proved successful and are being applied in the management of JRA. These developments have been facilitated by the advances in molecular biology which have heralded the advent of biodrugs (recombinant proteins) and gene therapy, in which specific genes can be introduced locally to enhance in vivo gene expression or suppress gene(s) of interest with a view to down-regulating inflammation. Some of these biodrugs, such as anti-tumor necrosis factor alpha (anti-TNFalpha), monoclonal antibodies (infliximab, adalimumab), TNF soluble receptor constructs (etanercept) and interleukin-1 receptor antagonist (IL-1Ra) have been tested and shown to be effective in RA. Etanercept has now been licensed for JRA. Clinical trials of infliximab in JRA are planned. Studies show that the clinical effects are transient, necessitating repeated treatments and the risk of vaccination effects. Anti-inflammatory cytokines such as IL-4, IL-10, transforming growth factor-beta and interferon-beta (IFN-beta) are undergoing clinical trials. Many of these agents have to be administered parenterally and production costs are very high; thus, there is a need

    Due to its severity and increasing epidemiology, arthritis needs no description. There are various forms of arthritis most of which are disabling, very painful, and common. In spite of breakthroughs in the field of drug discovery, there is no cure for arthritis that can eliminate the disease permanently and ease the pain. The present review focuses on some of the most successful drugs in arthritis therapy and their side effects. Potential new targets in arthritis therapy such as interleukin-1β, interleukin-17A, tumor necrosis factor alpha, osteopontin, and several others have been discussed here, which can lead to refinement of current therapeutic modalities. Mechanisms for different forms of arthritis have been discussed along with the molecules that act as potential biomarkers for arthritis. Due to the difficulty in monitoring the disease progression to detect the advanced manifestations of the diseases, drug-induced cytotoxicity, and problems with drug delivery; nanoparticle therapy has gained the attention of the researchers. The unique properties of nanoparticles make them highly attractive for the design of novel therapeutics or diagnostic agents for arthritis. The review also focuses on the recent trends in nanoformulation development used for arthritis therapy. This review is, therefore, important because it describes the relevance and need for more arthritis research, it brings forth a critical discussion of successful drugs in arthritis and analyses the key molecular targets. The review also identifies several knowledge gaps in the published research so far along with the proposal of new ideas and future directions in arthritis therapy. PMID:26345140

    Psoriasis is a chronic inflammatory disorder of the skin and joints. Although rarely life threatening, psoriasis can significantly impair quality of life (QOL) and cause considerable physical and psychological distress. Between 6 and 42% of patients with psoriasis develop psoriatic arthritis, which is characterized by stiffness, pain, swelling and tenderness of the joints. Nail psoriasis is highly prevalent in both plaque-type psoriasis and psoriatic arthritis and is found in approximately 50% of patients with psoriasis and in 80% of patients with psoriatic arthritis. Infliximab, a chimeric human-murine monoclonal antibody directed against tumour necrosis factor α, is approved in the USA and EU for the treatment of plaque psoriasis and psoriatic arthritis at a recommended dosage of 5 mg/kg administered by intravenous infusion at 0,2 and 6 weeks, then every 8 weeks thereafter. The EXPRESS and EXPRESS II trials demonstrated that infliximab is efficacious as induction and maintenance therapy in the treatment of moderate to severe plaque psoriasis and also improved health-related QOL. Infliximab is also efficacious in the treatment of psoriatic arthritis, as shown in the IMPACT and IMPACT II studies. Infliximab is generally well tolerated, with a similar adverse event profile in both psoriasis and psoriatic arthritis. The use of infliximab in three case reports is presented. The patients are similar to those normally seen by clinicians, and include a male patient with plaque psoriasis and a history of severe psoriatic arthritis who was corticosteroid dependent and in whom other systemic treatments were not effective or were not able to be used. This patient showed a rapid response to infliximab with no skin lesions or arthritis after 7 weeks' treatment. Infliximab was also safe and effective in the treatment of a female patient with plaque and nail psoriasis and a history of psoriatic arthritis. Importantly, this case report supports the efficacy of infliximab in

    Several advances have been made in the understanding of the pathogenesis, as well as in the clinical evaluation and treatment, of early inflammatory arthritis. The presence of anti-citrullinated protein antibodies (ACPAs) has emerged as a major new biomarker for use in clinical practice. The presence of ACPAs can be used to divide patients with early arthritis into subsets that are phenotypically similar but have varying pathogenetic and prognostic features. Although the detection of ACPAs is a major development in the diagnosis and prognosis of rheumatoid arthritis (RA), prediction of the outcome of arthritis at the individual level can still be much improved. For patients diagnosed with RA, and who have active polyarthritis, treatment is not dependent on the assessment of prognostic factors, as these patients are best treated with combination therapy; over 40% of these patients achieve remission with such treatment. In patients who present with oligoarthritis, however, management should be based on the assessment of prognostic factors. The success of early treatment of inflammatory arthritis and the recognition of a measurable preclinical phase of RA offer hope that treating the disease before it becomes clinically active might be possible.

    Twenty-eight pedigrees were ascertained through pairs of first-degree relatives diagnosed with rheumatoid arthritis (RA). RA was confirmed in 77 pedigree members including probands; the absence of disease was verified in an additional 261 pedigree members. Pedigree members were serologically typed for HLA. We used likelihood analysis to statistically characterize the HLA-linked RA susceptibility locus. The genetic model assumed tight linkage to HLA. The analysis supported the existence of an HLA-linked RA susceptibility locus, estimated the lifetime penetrance as 41% in male homozygotes and as 48% in female homozygotes. Inheritance was recessive in males and was nearly recessive in females. In addition, the analysis attributed 78% of the variance within genotypes to genetic or environmental effects shared by siblings. The genetic model inferred in this analysis is consistent with previous association, linkage, and familial aggregation studies of RA. The inferred HLA-linked RA susceptibility locus accounts for approximately one-fifth of the RA in the population. Although other genes may account for the remaining familial RA, a large portion of RA cases may occur sporadically. 79 refs., 9 tabs.

  19. The microbiome and rheumatoid arthritis

    2012-01-01

    Humans are not (and have never been) alone. From the moment we are born, millions of micro-organisms populate our bodies and coexist with us rather peacefully for the rest of our lives. This microbiome represents the totality of micro-organisms (and their genomes) that we necessarily acquire from the environment. Micro-organisms living in or on us have evolved to extract the energy they require to survive, and in exchange they support the physiological, metabolic and immune capacities that have contributed to our evolutionary success. Although currently categorized as an autoimmune disorder and regarded as a complex genetic disease, the ultimate cause of rheumatoid arthritis (RA) remains elusive. It seems that interplay between predisposing genetic factors and environmental triggers is required for disease manifestation. New insights from DNA sequence-based analyses of gut microbial communities and a renewed interest in mucosal immunology suggest that the microbiome represents an important environmental factor that can influence autoimmune disease manifestation. This Review summarizes the historical clues that suggest a possible role for the microbiota in the pathogenesis of RA, and will focus on new technologies that might provide scientific evidence to support this hypothesis.

    Medical strategy for rheumatoid arthritis (RA) has markedly advanced in recent years. The introductions of biologics and methotrexate as an anchor drug have made it possible to not only suppress pain and inflammation (clinical remission), but also to inhibit joint destruction (structural remission), leading to cure of the disease. In order to achieve this target, it is the most important to diagnose RA early and promote disease remission. However, since the condition and pathology are diverse among patients, optimal treatment for each patient is desired (personalized medicine). Treatment should be performed under consideration of the disease state such as activity, prognosis regarding joint destruction, and complications. It is also important to clarify the patient characteristics, such as responsiveness to the drugs and risk of adverse effects. Biomarkers, such as proteomics and pharmacogenomics (genetic polymorphism, etc.), are indispensable for personalized medicine. We have established a predictive model for methotrexate hepatotoxicity, consisting of 13 SNPs with a sensitivity of 100% and specificity of 89%, although the model should be validated with a larger-scale prospective study. RA is a multifactorial disorder with clinically heterogeneous features. Gene-environment interaction is closely involved in the production of anti-CCP antibodies (ACPA); thereafter, secondary stimuli of joints may lead to symptoms of RA. Joint injury, emotional stress, and infections often trigger the onset of RA. Cure can be achieved through complete remission by early aggressive treatment and returning to the pre-clinical state of RA with environmental improvement.

  1. Rheumatoid arthritis: Disease or syndrome?

    Rheumatoid arthritis (RA) has been described in the medical literature for over two hundred years, but its etiology remains unknown. RA displays phenotypic heterogeneity, and it is a relatively prevalent clinical entity: it affects approximately 1% of the population, resulting in enormous pathologic sequelae. Earlier studies targeting the cause(s) of RA suggested potential infectious involvement, whereas more recent reports have focused on a genetic origin of the disease. However, neither infection nor genetics, nor any other single factor is currently accepted as causative of RA. In this article we review studies relating to the etiology of RA, and those of several related matters, and we conclude that the literature indeed does provide insight into the causes underlying the initiation of RA pathogenesis. Briefly, given the remarkable phenotypic variation of RA, especially in its early stages, as well as a number of other characteristics of the condition, we contend that RA is not a discrete clinical entity with a single etiological source. Rather, we argue that it represents a common clinical endpoint for various starting points, each of which is largely guided by as yet poorly understood aspects of the genetic background of the affected individual. Adoption of this alternative view of the origin of RA will have significant consequences for future research and for development of new therapeutic interventions for this burdensome condition.

    The National Institute for Medical Research, London, England, was requested by the WHO Expert Committee on Biological Standardization to arrange a collaborative study of the serum pool they had obtained, to determine its suitability to serve as an international reference preparation of rheumatoid arthritis serum. A batch of this serum was assayed by 11 laboratories in 7 countries against 30 test preparations. On the basis of the results obtained, the serum has been established as the International Reference Preparation of Rheumatoid Arthritis Serum and the International Unit of Rheumatoid Arthritis Serum has been defined as the activity contained in 0.171 mg of the international reference preparation. A description is also given of the British reference preparation of rabbit antibody to sheep red blood cells (amboceptor) and this material was also tested in the collaborative study. PMID:5310143

    Septic arthritis due to Salmonella in systemic lupus erythematosus is rare. We report a case of septic arthritis by Salmonella enteritidis which occurred during the evolution of systemic lupus erythematosus. A 23-year-old man was diagnosed as suffering from systemic lupus erythematosus. This diagnosis was taken on the basis of general symptoms, skin lesions, hemolytic anemia, thrombocytopenia and glomerulonephritis (class III). He was treated with three methylprednisolone boli related by high-dose regimen of prednisolone. A month and a half later, he presented fever with monoarthritis of the left elbow without any other new sign of underlying systemic disease. Bacteriological examinations isolated S. enteritidis. The patient improved with antibiotics and joint lavage. Feverish monoarthritis in systemic lupus erythematosus should be suspect to be septic arthritis. Appropriate treatment should be promptly instituted to improve the prognosis.

    Psoriatic arthritis (PsA) is characterised by several unique clinical features that differentiate it from rheumatoid arthritis (RA). Attempts to identify immunopathological mechanisms, some shared with psoriasis, that underlie these differences from RA have been most challenging. Recent research studies, however, highlight novel findings in PsA at the molecular, cellular, and tissue levels that form the basis for a new understanding of this relatively common form of inflammatory arthritis. In particular, the availability of new, biological antitumour necrosis factor α therapies have allowed further insight into the immunopathology of psoriasis and PsA. This brief review focuses on immunohistological studies in psoriatic skin, PsA synovium, and bone to demonstrate how these data advance our knowledge of disease pathogenesis. PMID:15708930

    Reactive oxygen species (ROS) have been shown to play a role in the pathogenesis of arthritides. Luminol was used as the primary reporter of ROS and photons resulting from the chemiluminescence reaction were detected using a super-cooled CCD photon counting system. Luminol was injected intravenously into groups of animals with different models of arthritis. Imaging signal correlated well with the severity of arthritis in focal and pan-arthritis as determined by histological measurement of ROS by formazan. Measurements were highly reproducible, sensitive, and repeatable. In vivo chemiluminescence imaging is expected to become a useful modality to elucidate the role of ROS in the pathogenesis of arthritides and in determining therapeutic efficacy of protective therapies.

    A close examination of the hands of people depicted in paintings of the Flemish school showed that in five paintings there were figures with hand lesions resembling those of rhematoid arthritis. Although none of the deformities or swellings are indisputable examples of rheumatoid arthritis, they do at least suggest that the painters must have been confronted with rheumatoid-like lesions in their models. In two other paintings there were signs of rheumatic fever and of temporal arteritis. No arthritic lesions were found in the works of painters of the Italian Renaissance, probably because they are less detailed. The finding of rheumatoid deformities in the Flemish paintings does, however, question the general belief that rheumatoid arthritis is a condition that has arisen relatively recently.

    TNF-blocking agents, non-biological disease-modifying anti-rheumatic drugs (nbDMARDs) and non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed treatments in psoriatic arthritis. A large proportion of patients do not respond to these medications, although unfortunately clinically useful biomarkers that predict future response are currently lacking. Several candidate gene polymorphisms have been associated with responses to biologic therapies and nbDMARDs; however, replication and validation of these variants in large prospective psoriatic arthritis cohorts are required before translating these to clinical practice. In this review, we discuss the advances made in pharmacogenetics of treatment response in psoriatic arthritis to date, with focus on biologic therapies approved for use, nbDMARDs and NSAIDs, as well as outline emerging methodologies to obtain data that will help inform a future precision medicine approach in this condition.

    In the early 1970s, Moll and co-workers formulated the unified concept of spondyloarthritides, a group of conditions sharing similar clinical features. Subsequently, criteria for their classification have been proposed by Amor and coworkers, the European Spondylarthropathy Study Group, and the Assessment in SpondyloArthritis international Society. Opinion, however, is divided between those who believe that the different entities of the complex represent the variable expression of the same disease ("lumpers") and those who think that these should be considered separately but under the same umbrella ("splitters"). Several sets of criteria have been proposed for psoriatic arthritis (PsA), the most recent being the ClASsification for Psoriatic Arthritis (CASPAR) criteria. According to some authors, there are persuasive arguments to support the view of PsA as a distinct entity.

    Total lymphoid irradiation was administered to 32 patients with intractable rheumatoid arthritis. Twenty-four patients showed at least a 25% improvement in 3 of 4 disease activity parameters, which persisted during the followup period of up to 48 months. Eight of the 32 patients required adjunctive immunosuppressive drug therapy to maintain improvement. Four patients died after total lymphoid irradiation; the causes of death were acute myocardial infarction (1 patient), pulmonary embolism (1 patient), and rheumatoid lung disease complicated by respiratory infection (2 patients). After therapy, patients exhibited a prolonged reduction in the number and function of circulating T helper cells.

    PubMed

    Cerinic, M M; Konttinen, Y; Generini, S; Cutolo, M

    1998-05-01

    Primary afferent nociceptive and peptidergic efferent nerves are sensitized in arthritis and thus easily stimulated by mechanical and chemical stimuli. This leads to increased or disturbed release of neuropeptides from nerve terminals. This local (at the site of stimulation), expanded (expanded and additional receptive fields), and remote (cross-spinal reflexes) neuropeptide release leads to disturbed tissue homeostasis and neurogenic inflammation. In arthritis, raised levels of neuropeptides were detected in the synovial fluid, whereas nerve fibers were lacking in the synovial tissue. It has been hypothesized that cycles of nerve fiber destruction and degeneration follow the cycles of joint inflammation. This evidence suggests that the peripheral nervous system, through its neuropeptides, may contribute to the generation of inflammation, i.e., "neurogenic inflammation." Altered hypothalamic-pituitary-adrenocortical axis function and sex hormone status have been suggested to contribute to the development and persistence of arthritis. In particular, current evidence indicates that glucocorticoid secretion is closely and reciprocally interrelated with inflammation, and that an adrenal insufficiency is present in many forms of immune-mediated arthritis. Conversely, gonadal steroids seem to play a central role as predisposing factors in many forms of arthritis, with estrogens involved as immuno-enhancing hormones and androgens as natural immunosuppressors. Functional receptors for sex hormones have been described in cells involved in the immune response and, after activation, the hormone-receptor complex might modulate the expression of selected cytokines. The possibility of targeting the efferent nerves with specific peptides and replacement therapies with selected steroid hormones may represent a new and potentially efficient and natural system of modulation of the arthritis.

    Peripheral joint involvement is a common, potentially debilitating feature of psoriatic arthritis (PsA). Joint involvement is commonly symmetrical and polyarticular similar to rheumatoid arthritis (RA) but it can also be oligoarticular, asymmetrical or occasionally monoarticular. Involvement of the distal interphalangeal joints is a feature which distinguishes PsA from RA. Articular involvement in PsA can be severe with a mutilating arthropathy found in about 5%. These patients are characterised clinically by digital shortening and on radiographs by erosion on both sides of the joint and/or osteolysis. Treatments targeting joint disease frequently reduces symptoms and signs resulting in prevention of damage progression.

    This study was conducted to determine the efficacy of sodium hyaluronate (SH) with antibiotic therapy and joint lavage for reducing acute inflammatory and degenerative changes induced by septic arthritis. Septic arthritis was induced in six adult horses by inoculating the tarsocrural joints with 1 x 10(4) colony-forming units of Staphylococcus aureus. When clinical signs appeared, trimethoprim-sulphamethoxazole (30 mg/kg bodyweight [bwt] daily) and phenylbutazone (4.4 mg/kg bwt sid) were administered and continued until termination of the study (Treatment Day 18). Twenty-four hours post inoculation, all joints were lavaged with sterile lactated Ringer's solution. Following lavage, one joint of each horse was injected with 10 mg of SH, and the contralateral joint served as the control. Sodium hyaluronate treated joints showed significant reductions in lameness, tarsal circumference and synovial fluid protein and WBC concentrations. The synovial membrane of the SH-treated joints contained less cellular infiltrate, less granulation tissue formation and retained a more normal villous structure compared with controls. The total glycosaminoglycan loss from the articular cartilage in the SH treated joints was consistently less than that from the control joints; however, this difference was not statistically significant. Sodium hyaluronate with joint lavage appears to be more beneficial than lavage alone for treatment of septic arthritis.

    Introduction Tuberculosis remains a major public health problem in developing countries. Diagnosing extrapulmonary tuberculosis can be difficult, as it requires a higher index of suspicion than primary tuberculosis. Extrapulmonary tuberculosis may mimic malignancies and many other diseases, so it should be included in the differential diagnosis. Here, we present a case of extrapulmonary tuberculosis associated with Pott’s disease and hip arthritis in a patient who recovered after 12 months of antituberculosis therapy. Case Presentation A 16-year-old girl presented to the outpatient otolaryngology clinic with painless swelling of the neck, and to the physical medicine and rehabilitation clinic with complaints of hip and low back pain that mimicked spondyloarthropathy. She was eventually referred to the outpatient pediatric clinic. Her acute-phase reactants were high, and hilar lymphadenopathy was evident on chest x-ray. On computerized tomography, a Pott’s abscess involving the T8, T9, and T10 vertebrae was suspected. Magnetic resonance imaging of the dorsal vertebrae and hip was performed, and a Pott’s abscess and hip tuberculous arthritis were confirmed. The patient had been exposed to tuberculosis 10 years earlier, and her purified protein derivative (PPD) test was 16 mm. After antituberculosis treatment, our patient recovered and the Pott’s disease and hip tuberculous arthritis regressed. Conclusions Extrapulmonary tuberculosis may mimic many other diseases, so it should be kept in mind in the differential diagnosis. It is essential to diagnose osteoarticular tuberculosis early, as late diagnosis or inadequate treatment may cause permanent disability.

    We present the case of a healthy 18-year-old female who presented with history of an acute onset, painful, swollen right ankle joint. Microbiologic samples from the ankle aspirate grew Neisseria meningitidis. She had had no previous contact with a patient with meningitis nor any existing or preceding clinical symptoms of meningitis. She was treated with surgical drainage with mini-open arthrotomy and a repeat washout at 48 hours. The identification of the organism was expedited using the Analytical Profiling Index (bioMérieux UK, Basingstoke, UK). Our patient was treated with 2 weeks of third-generation cephalosporin antibiotics. At the final follow-up visit, the inflammatory markers had returned to normal, with a normal ankle joint and no evidence of long-term sequelae of septic arthritis. Primary septic arthritis with N. meningitidis is exceptionally rare in the adult population and has been most often reported in the knee. To the best of our knowledge, this is the first reported case of primary septic arthritis of the native adult ankle joint in a healthy individual due to N. meningitides that was diagnosed and treated appropriately with no residual sequelae of the disease.

    X-linked agammaglobulinemia (XLA) is a primary immunodeficiency disease caused by mutations in the Bruton's tyrosine kinase (BTK) gene. XLA can also present in combination with juvenile idiopathic arthritis (JIA), the major chronic rheumatologic disease in children. We report herein the first known case of a juvenile patient diagnosed with XLA combined with JIA that later developed into invasive Klebsiella pneumoniae polyarticular septic polyarthritis. An additional comprehensive review of XLA combined with JIA and invasive K. pneumoniae septic arthritis is also presented. XLA was identified by the detection of BTK mutations while the diagnosis of JIA was established by clinical and laboratory assessments. Septic arthritis caused by invasive K. pneumoniae was confirmed by culturing of the synovia and gene detection of the isolates. Invasive K. pneumoniae infections can not only result in liver abscesses but also septic arthritis, although this is rare. XLA combined with JIA may contribute to invasive K. pneumoniae infection.

    Abstract Arthritic diseases are a major cause of disability and morbidity, and cause an enormous burden for health and social care systems globally. Osteoarthritis (OA) is the most common form of arthritis. The key risk factors for the development of OA are age, obesity, joint trauma or instability. Metabolic and endocrine diseases can also contribute to the pathogenesis of OA. There is accumulating evidence to suggest that OA is a whole-organ disease that is influenced by systemic mediators, inflammaging, innate immunity and the low-grade inflammation induced by metabolic syndrome. Although all joint tissues are implicated in disease progression in OA, articular cartilage has received the most attention in the context of aging, injury and disease. There is increasing emphasis on the early detection of OA as it has the capacity to target and treat the disease more effectively. Indeed it has been suggested that this is the era of “personalized prevention” for OA. However, the development of strategies for the prevention of OA require new and sensitive biomarker tools that can detect the disease in its molecular and pre-radiographic stage, before structural and functional alterations in cartilage integrity have occurred. There is also evidence to support a role for biomarkers in OA drug discovery, specifically the development of disease modifying osteoarthritis drugs. This Special Issue of Biomarkers is dedicated to recent progress in the field of OA biomarkers. The papers in this Special Issue review the current state-of-the-art and discuss the utility of OA biomarkers as diagnostic and prognostic tools. PMID:26954784

    Rheumatoid arthritis (RA) is the most common connective tissue disease of autoimmune origin. The disease is characterized by chronic inflammation leading to bone erosions and organ involvement. RA is a progressive disease. It affects the quality of life, leading to disability and death mainly due to premature cardiovascular disease. Early diagnosis and appropriate treatment are essential for prognosis and quality of life improvement. In 2010 the American College of Rheumatology (ACR) and The European League Against Rheumatism (EULAR) established new RA classification criteria. Besides clinical symptoms it includes two immunologic criteria: rheumatoid factor (RF) and anti-citrullinated protein antibodies (anti-CCP antibodies). RF is the first well-known RA immunologic marker. It is observed in 80-85% of patients with RA. Elevated serum level of RF has been associated with increased disease activity, radiographic progression, and the presence of extraarticular manifestations. The sensitivity of RF is 50-90%, and specificity is 50-95%. Anti-CCP antibodies appear to be a more specific marker than RF. They are often present at the very beginning of the disease, or even years before the first symptoms. The prognostic value of anti-CCP antibodies is well established. High serum level of anti-CCP correlates with poor prognosis and early erosions of the joints. The sensitivity of anti-CCP2 is 48-80%, and specificity is 96-98%. New immunologic markers include anti-carbamylated protein antibodies (anti-CarP) and antibodies against heterogeneous nuclear ribonucleoproteins (anti-hnRNP A2/B1, RA33). Scientists aim to identify a highly sensitive and specific biomarker of the disease that not only has diagnostic and prognostic value but also may predict the response to treatment.

    The aim was to further characterize the SKG model of rheumatoid arthritis (RA) and its potential for studying intervention treatments, with special focus on bone targeting therapies. Three individual studies were conducted, using a total of 71 SKG mice, comparing arthritis induction with mannan versus zymosan A, female versus male mice, and the effect of dexamethasone intervention treatment initiated at different time points after arthritis induction. Hind paws were embedded undecalcified in methyl methacrylate, and sections were stained with Masson-Goldner trichrome. Areal Bone Mineral Density (aBMD) of the femora was determined with pDXA. RNA was extracted from the hind paws followed by the quantification by reverse transcriptase PCR. SKG mice stimulated with mannan presented a higher arthritis score than mice stimulated with zymosan A. Female SKG mice developed a more severe arthritis than male SKG mice. Dexamethasone inhibited arthritis clinically as well as histologically when the treatment was initiated prophylactically or within the first week of arthritis. Femoral aBMD was lower in animals with arthritis than in control animals. The RANKL RNA expression was elevated in arthritic mice, whereas OPG RNA expression was unchanged. The results suggest mannan as arthritis inductor and female instead of male mice in experiments as well as an optimal time window for the initiation of treatment. Systemic bone loss as well as local up regulation of RANKL was present early in SKG arthritis. These results demonstrate that SKG arthritis is a suitable new model for evaluating therapies in RA.

    Interleukin-6 is a multifunctional cytokine that is critical for T/B-cell differentiation and maturation, immunoglobulin secretion, acute-phase protein production, and macrophage/monocyte functions. Extensive research into the biology of IL-6 has implicated IL-6 in the pathophysiology and pathogenesis of RA. An anti-murine IL-6 mAb that neutralizes mouse IL-6 activities was tested in animal model of collagen-induced arthritis. Prophylactic treatment with anti-IL-6 mAb significantly reduced the incidence and severity of arthritis compared to control mAb treated mice. The mitogenic response of B and T cells isolated from the lymph nodes of anti-IL-6 treated mice was significantly reduced compared to cells isolated from control mAb treated mice. The overall histopathology score for paws from the anti-IL-6 treated mice was significantly reduced when compared to paws from mice treated with control mAb, including both inflammatory (synovitis and pannus) and erosive (erosions and architecture) parameters. Reduced loss of cartilage matrix components was also observed in the anti-IL-6 treated mice. Collectively, these data suggest that IL-6 plays a major role in the pathophysiology of rheumatoid arthritis, and thus support the potential benefit of anti-IL-6 mAb treatment in rheumatoid arthritis patients.

    There is strong diurnal variation in the symptoms and severity of chronic inflammatory diseases, such as rheumatoid arthritis. In addition, disruption of the circadian clock is an aggravating factor associated with a range of human inflammatory diseases. To investigate mechanistic links between the biological clock and pathways underlying inflammatory arthritis, mice were administered collagen (or saline as a control) to induce arthritis. The treatment provoked an inflammatory response within the limbs, which showed robust daily variation in paw swelling and inflammatory cytokine expression. Inflammatory markers were significantly repressed during the dark phase. Further work demonstrated an active molecular clock within the inflamed limbs and highlighted the resident inflammatory cells, fibroblast-like synoviocytes (FLSs), as a potential source of the rhythmic inflammatory signal. Exposure of mice to constant light disrupted the clock in peripheral tissues, causing loss of the nighttime repression of local inflammation. Finally, the results show that the core clock proteins cryptochrome (CRY) 1 and 2 repressed inflammation within the FLSs, and provide novel evidence that a CRY activator has anti-inflammatory properties in human cells. We conclude that under chronic inflammatory conditions, the clock actively represses inflammatory pathways during the dark phase. This interaction has exciting potential as a therapeutic avenue for treatment of inflammatory disease.—Hand, L. E., Hopwood, T. W., Dickson, S. H., Walker, A. L., Loudon, A. S. I., Ray, D.

    To determine the clinical evolution of Lyme arthritis, 55 patients who did not receive antibiotic therapy for erythema chronicum migrans were followed longitudinally for a mean duration of 6 years. Of the 55 patients, 11 (20%) had no subsequent manifestations of Lyme disease. From 1 day to 8 weeks after disease onset, 10 of the patients (18%) began to have brief episodes of joint, periarticular, or musculoskeletal pain for as long as 6 years, but they never developed objective joint abnormalities. From 4 days to 2 years after disease onset, 28 (51%) had one episode or began to have intermittent attacks of frank arthritis, primarily in large joints; a few had polyarticular movement. The total number of these patients who continued to have recurrences decreased by 10% to 20% each year. The remaining 6 patients (11%) developed chronic synovitis later in the illness; of these, 2 (4%) had erosions, and 1 (2%), permanent joint disability. The spectrum of Lyme arthritis ranges from subjective joint pain, to intermittent attacks of arthritis, to chronic erosive disease.

  12. The association between arthritis and the weather

    Despite the pervasiveness of the idea that arthritis is influenced by the weather, scientific evidence on the matter is sparse and non-conclusive. This study, conducted in the Australian inland city of Bendigo, sought to establish a possible relationship between the pain and rigidity of arthritis and the weather variables of temperature, relative humidity, barometric pressure, wind speed and precipitation. Pain and rigidity levels were scored by 25 participants with osteoarthritis and/or rheumatoid arthritis four times per day for 1 month from each season. Mean pain and rigidity scores for each time of each day were found to be correlated with the meteorological data. Correlations between mean symptoms and temperature and relative humidity were significant (P <0.001). Time of day was included in the analysis. Stepwise multiple regression analysis indicated that meteorological variables and time of day accounted for 38% of the variance in mean pain and 20% of the variance in mean rigidity when data of all months were considered. A post-study telephone questionnaire indicated 92% of participants perceived their symptoms to be influenced by the weather, while 48% claimed to be able to predict the weather according to their symptoms. Hence, the results suggest (1) decreased temperature is associated with both increased pain and increased rigidity and (2) increased relative himidity is associated with increased pain and rigidity in arthritis sufferers.

    SYNOPSIS In the United States, Lyme arthritis is the most common feature of late stage infection with the tick-borne spirochete, Borrelia burgdorferi, usually beginning months after the initial tick bite. However, in some patients, including most of those seen today, the earlier phases of the infection are asymptomatic and arthritis is the presenting manifestation of the disease. Patients with Lyme arthritis have intermittent or persistent attacks of joint swelling and pain in one or a few large joints, especially the knee, usually over a period of several years, without prominent systemic manifestations. Serologic testing is the mainstay of diagnosis. Synovial fluid PCR testing for B. burgdorferi DNA is often positive prior to treatment, but it is not a reliable marker of spirochetal eradication after antibiotic therapy. Responses to oral or intravenous antibiotic treatment are generally excellent, although a small percentage of patients have persistent synovitis after 2-3 months of oral and IV antibiotics, which usually then responds to anti-inflammatory therapies, disease modifying anti-rheumatic drugs (DMARDs), or synovectomy. This chapter reviews the clinical manifestations, diagnosis, and management of Lyme arthritis. PMID:25999223

    Collagens, the most abundant proteins in animals, also occur in some recently described nucleocytoplasmic large DNA viruses such as Mimiviridae, which replicate in amoebae. To clarify the impact of viral collagens on the immune response of animals exposed to Mimiviridae, we have investigated the localization of collagens in Acanthamoeba polyphaga mimivirus particles and the response of mice to immunization with mimivirus particles. Using protein biotinylation, we have first shown that viral collagen encoded by open reading frame L71 is present at the surface of mimivirus particles. Exposure to mimivirus collagens elicited the production of anti-collagen antibodies in DBA/1 mice immunized intradermally with mimivirus protein extracts. This antibody response also targeted mouse collagen type II and was accompanied by T-cell reactivity to collagen and joint inflammation, as observed in collagen-induced arthritis following immunization of mice with bovine collagen type II. The broad distribution of nucleocytoplasmic large DNA viruses in the environment suggests that humans are constantly exposed to such large virus particles. A survey of blood sera from healthy human subjects and from rheumatoid arthritis patients indeed demonstrated that 30% of healthy-subject and 36% of rheumatoid arthritis sera recognized the major mimivirus capsid protein L425. Moreover, whereas 6% of healthy-subject sera recognized the mimivirus collagen protein L71, 22% of rheumatoid arthritis sera were positive for mimivirus L71. Accordingly, our study shows that environmental exposure to mimivirus represents a risk factor in triggering autoimmunity to collagens. PMID:24173233

    Systemic-onset juvenile idiopathic arthritis (SoJIA) is a systemic inflammatory disease which has up to now been classified as a category of juvenile idiopathic arthritis. However, in this context, systemic inflammation has been associated with dysregulation of the innate immune system, suggesting that it may rather be part of the spectrum of autoinflammatory disorders. The disease is in fact unique with regard to the other JIA categories, in terms of clinical manifestations, prognosis, and response to conventional immunosuppressant therapies. It is characterized clinically by fever, lymphadenopathy, arthritis, rash, and serositis. IL-1 and IL-6 play a major role in the pathogenesis of SoJIA, and treatment with IL-1 and IL-6 inhibitors has shown to be highly effective. However, complications of SoJIA, including macrophage activation syndrome, limitations in functional outcome by arthritis and long-term damage from chronic inflammation continue to be a major issue in patients' care. Recent advances on the pathogenesis and treatment have revolutionized the care and prognosis of this potentially life-threatening pediatric condition.

    The aim of this cross-sectional study was to review the incidence of the dry eye syndrome in rheumatoid arthritis (RA) patients, evaluate the association among the incidence of the dry eye syndrome, presence of positive rheumatoid factor (RF), the RA stage, and the duration of the disease. The group consisted of altogether 100 patients, 16 men and 84 women; the average age was 58.9 years (SD 14.6). The average duration of RA was 12.3 years, SD 11.0. In each patient, the Schirmer test I was performed, the presence of the LIPCOF (Lid Parallel Conjunctival Folds) on the slit lamp was assessed, the BUT (Tear Break-Up Time) was measured and vital fluorescein staining was performed. In each patient the data of the presence or absence of the RF in the serum, RA severity according to the X-ray examination, and the disease duration were recorded. The Pearson's association test for nominal variables was used for statistical evaluation of the association between the rheumatoid arthritis presence and the dry eye syndrome. In our group of 100 patients, the Schirmer test I was positive in 67% of patients. Positive BUT was marked in 84 % of patients. The conjunctival folds were present in 45 % of patients only. The pathological findings after cornea fluorescein staining appeared in 18 % of patients. The dry eye syndrome incidence was marked in 74% of patients with RA. Subjective difficulties were declared by 38.3% of patients only. The local treatment was already established in 23.0% of patients only. We did not find statistically significant correlation between the RF positive rheumatoid arthritis appearance and dry eye syndrome, nor between the stage of the rheumatoid arthritis and presence of the dry eye syndrome. We proved statistical connection between the presence of dry eye syndrome and the duration of rheumatoid arthritis longer than 10 years. Keratoconjunctivitis sicca is the most common ocular complication in rheumatoid arthritis patients. We proved the connection

    Hematogenous Salmonella osteomyelitis is uncommon in immunocompetent hosts, but occurs with some regularity in immunosuppressed patients affected by systemic lupus erythematosus (SLE). Surgical debridement with resection of compromised tissue is central to the surgical management of osteomyelitis. Persistence of septic arthropathy may result from inadequate debridement, areas of osteonecrosis (ON), and an abnormal cellular and humoral dysregulation characteristic of SLE. We describe a 53-year-old Hispanic female with SLE on immunosuppressive therapy, who developed acute salmonella-induced septic arthritis and osteomyelitis of both knees associated with ON and recurrent SLE synovitis. She received prolonged antibiotic therapy and an extensive surgical debridement as part of a successful two-stage bilateral total knee replacement. This report illustrates the significance of Salmonella enterica infection in SLE patients, and the role of underlying bone and joint pathology such as bone infarcts, sub-acute osteomyelitis, and SLE synovitis.

    Equisetum giganteum is a plant used in traditional medicine as diuretic. From our knowledge this is the first time this plant is tested in an in vivo model of acute inflammation. To evaluate the effect of aqueous extract of giant horsetail (AEGH) as immunomodulatory therapy, antigen-induced arthritis (AIA) was generated in mice with methylated bovine serum albumin (mBSA). Inflammation was evaluated by articular nociception, leukocytes migration and lymphocyte proliferation. AEGH reduced nociception at 3, 6 and 24 h (P < 0.01), decreased leukocyte migration (P < 0.015), and inhibited lymphocyte proliferation stimulated with Concanavalin A and Lipopolysaccharide (P < 0.05). In conclusion, AEGH has an anti-inflammatory potential in acute model of inflammation, as well as immunomodulatory effect on both B and T lymphocytes, with an action independent of cytotoxicity.

    Psoriasis and psoriatic arthritis are chronic inflammatory diseases of the skin and joints, but the relationship between them has not been fully understood. Since the delay of treatment for psoriatic arthritis can result in the severe deformities, it is important to identify the pathological triggers of the arthritis. On the other hand, many reports suggest that the changes of immune balance during pre/postpartum period are associated with the state of autoimmune diseases. Here, we report a female case with psoriasis whose arthritis may be triggered by the delivery. Our report suggests that immune tolerance may diminish in the postpartum period, which may alter the susceptibility to arthritis. Female patients should be followed-up carefully during postpartum period against the development of arthritis.

    Th2–eosinophil immune responses are well known for mediating host defence against helminths. Herein we describe a function of Th2–eosinophil responses in counteracting the development of arthritis. In two independent models of arthritis, Nippostrongylus brasiliensis infection leads to Th2 and eosinophil accumulation in the joints associated with robust inhibition of arthritis and protection from bone loss. Mechanistically, this protective effect is dependent on IL-4/IL-13-induced STAT6 pathway. Furthermore, we show that eosinophils play a central role in the modulation of arthritis probably through the increase of anti-inflammatory macrophages into arthritic joints. The presence of these pathways in human disease is confirmed by detection of GATA3-positive cells and eosinophils in the joints of rheumatoid arthritis patients. Taken together, these results demonstrate that eosinophils and helminth-induced activation of the Th2 pathway axis effectively mitigate the course of inflammatory arthritis. PMID:27273006

    To the best of our knowledge, the association of rheumatoid arthritis and tabetic arthropathy has never been described before in the literature. We report here a first observation. We report the case of a 50-year-old man, treated for syphilitic arthritis evolving for 4 years, who presented with a table of rheumatoid arthritis. The diagnosis of rheumatoid arthritis was established according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria (ACR/EULAR). The treatment was based on weekly injection of methotrexate and a symptomatic treatment by corticosteroid. The association of rheumatoid arthritis and tabetic arthropathy is rare, to our knowledge this is the first case reported. This case reminds us that a neuropathic arthropathy as tabetic arthropathy, although it is rare, can be associated in a sporadic or exceptional way with other rheumatic disease like rheumatoid arthritis. A physiopathological link between the both diseases remains to be proved.

  16. Psychological aspects of pain in rheumatoid arthritis: a review.

    PubMed

    Skevington, S M

    1986-01-01

    Pain in rheumatoid arthritis (RA) is reviewed from a socio-cognitive perspective. Questions are raised about the usefulness of the distinction between organic vs non-organic pain patients, and alternative explanations for the behaviour of seronegatives is presented. A case based on physiology and behaviour is made for more studies of the acute and prechronic stages of RA. Four major areas of methodology are considered: studies of lay explanations about RA show that people hold relatively accurate views about the nature of pain in RA, and where causal explanations are given for pain and illness, this is conducive to good mental health. A section on the measurement of pain addresses issues about the applicability and standardisation of scales, and welcomes the move from the exclusive use of quantitative to qualitative multidimensional measures. The pain language of RA is described. Experimental studies of pain in RA appear to be of limited use. A review of activities and functional disability indicates that cognitive and behaviour modification techniques appear to have most promise in motivating chronic patients to be more active, and to comply with medication, as well as improving mental health. In a discussion of successful therapies, the principles of reducing uncertainty and increasing perceptions of control are the underlying features. However the reliability of cognitive therapies in the treatment of RA so far remains unproven.

    A 75-year-old man who developed disseminated trichosporonosis had a long history of immunosuppressive therapy with weekly methotrexate and low-dose prednisolone for rheumatoid arthritis (RA). He had been administered 30 mg of prednisolone per day for organizing pneumonia, probably due to the RA, for about 3 months before admission for a lumbar compression fracture. He then developed bilateral aspiration pneumonia with pleural effusion, treated successfully with broad-spectrum antibiotics meropenem and ciprofloxacin, and fluid management. He then developed acute, progressive respiratory failure with changes in both lung lobes in chest computed tomography (CT). Meropenem, ciprofloxacin, micafungin, and pulsed steroid administration were ineffective. He died of respiratory failure, after which Trichosporon asahii was first detected in blood and urine culture. Disseminated trichosporonosis was determined based on positive blood culture, elevated serum glucuronoxylomannan antigen and beta-D glucan, and the man's lack of clinical progress. He had numerous risk factors for trichosporonosis, including neutrophilic dysfunction due to prolonged steroid therapy, administration of broad-spectrum antibiotics and micafungin, and central venous catheterization. Disseminated trichosporonosis is a chiefly hematological infection and case reports without hematological disorders are rare, so we report this instructive case.

  18. Clinical features of rheumatoid arthritis-associated interstitial lung disease.

    PubMed

    2015-10-07

    Interstitial lung disease (ILD) is the most common extra-articular manifestations of rheumatoid arthritis (RA) in the lung. This study aimed to identify clinical features of RA-associated ILD (RA-ILD). Patients with RA were retrospectively enrolled and sub-classified as RA-ILD or RA without ILD based on high-resolution computed tomography imaging. Pulmonary function testing parameters and levels of RA-related biomarkers, tumour markers, and acute-phase proteins were compared between the two groups. Logistic regression model was used to assess the strength of association between RA-ILD and clinical features of interest. Receiver operating characteristic analysis was performed to assess potential predictive value of clinical features for detecting RA-ILD. Comparison analysis indicated that the percentage of predicted value of total lung capacity, inspiratory capacity, and diffusion capacity of the lung for carbon monoxide (DLCO) were reduced in patients with RA-ILD. Tumour markers CA15-3 and CA125 were increased in patients with RA-ILD. Logistic regression analysis revealed that decreased DLCO was related to the increased likelihood of RA-ILD (OR = 0.94, 95%CI = [0.91, 0.98]). The cut-off point at 52.95 percent of predicted value could sensitively discriminate RA patients with or without ILD. Our study suggested that DLCO value could be a useful tool for detecting ILD in patients with RA.

  19. In situ hybridization of IL-6 in rheumatoid arthritis.

    IL-6, an important mediator of the acute phase response, has been implicated in the pathogenesis of rheumatoid arthritis (RA). Many cell types including macrophages, T cells, B cells, endothelial cells and fibroblasts can produce this cytokine and production is largely regulated at the level of gene transcription or mRNA stabilization. In this paper we have first measured the levels of IL-6 activity in synovial fluid (SF) and serum from patients with RA and then localized IL-6-producing cells in the synovium by in situ hybridization combined with immunophenotyping. Patients with RA had raised levels of IL-6 in both SF and serum compared with patients with osteoarthritis and age-matched healthy controls. In individual RA patients tested serially after admission to hospital, serum IL-6 was initially raised and, unexpectedly, increased with clinical improvement. In situ hybridization of IL-6 mRNA showed positive cells both in the lymphocyte-rich aggregates and adjacent to small blood vessels. With immunophenotyping it was found that cells containing IL-6 mRNA were often in contact with CD14+ tissue macrophages and double immunophenotyping revealed that immunoreactive IL-6 was often associated with synovial T cells.

    Classic and definite rheumatoid arthritis affects from 0.5 to 1 percent of the United States' population between the ages of 20 and 80. In the age group of 55 to 75 years, this figure increases to 4.5 percent. In addition to the pain and suffering produced by this disease, family structure is dramatically affected--the divorce rate for patients with rheumatoid arthritis is 70 percent above that for the general population. Rheumatoid arthritis also results in serious economic loss to society. In 1983, the direct cost (out-of-pocket expense for medical care) was $777 million, and the indirect cost (loss of productivity) was $215 million, with a total of approximately $1 billion. The average person with stage III rheumatoid arthritis suffers a 60 percent decline in earnings during the first six years after onset of the disease. Recent studies have indicated that the ability to remain employed depends at least as much on job-related factors as on the extent of disease or success of medical treatment. Job autonomy or the ability to control one's working conditions is the most important factor. Other important variables are education, seniority, and work that is not excessively physically demanding. Good transportation between home and job is also an essential requirement for remaining employed. There are few data available on the cost/benefit ratio of the treatment of rheumatoid arthritis. An 18-month study showed a trend toward greater improvement in patients given optimal care by a team of experts in a medical center as compared with average treatment provided in the community. A study in Scotland on cost of hospitalization of 366 patients (about one half underwent surgery) showed cost benefits of xi 14,000 to xi 131,000 over a five- to 10-year period for those who returned to work. Patients who did not return to work incurred medical costs of xi 100,000. There is little question that more effective medical treatment and better rehabilitation strategies for people

    Rat bite fever is rare in Western countries. It can be very difficult to diagnose as blood cultures are typically negative and a history of rodent exposure is often missed. Unless a high index of suspicion is maintained, the associated polyarthritis can be mistaken for rheumatoid arthritis. We report a case of culture-positive rat bite fever in a 46-year-old female presenting with fever and polyarthritis. The clinical presentation mimicked rheumatoid arthritis. Infection was complicated by discitis, a rare manifestation. We discuss the diagnosis and management of this rare zoonotic infection. We also review nine reported cases of rat bite fever, all of which had an initial presumptive diagnosis of a rheumatological disorder. Rat bite fever is a potentially curable infection but can have a lethal course if left untreated. PMID:27366177

Personal advocacy is centred on the experiential expertise of the individual affected by the condition, whereas group advocacy is grounded on patient-centred strategies and actions. The first patient advocacy groups for arthritis were set up over 20 years ago in the USA and have subsequently spread to many other countries. This paper discusses the growth and impact of personal advocacy as well as recent developments in group advocacy in the Asia-Pacific region, Europe, and North America, in terms of arthritis awareness, research, corporate partnerships, and the Bone and Joint Decade global initiative.

    Juvenile rheumatoid arthritis (JRA) is the most common rheumatologic disease in children. Moreover, multiple sclerosis (MS) is the most frequent demyelinating disease and has been associated with various chronic inflammatory diseases. However, its association with JRA has not been frequently described. Autoimmunity in both JRA and MS has been documented in the scientific literature, although there has been no definitive finding that patients with JRA are prone to the development of MS. An increasing frequency of MS resulting from an increased use of antitumor necrosis factor agents in the treatment of rheumatoid arthritis and other chronic inflammatory diseases has been reported recently. In this study, we report on the development of MS in a patient with JRA who did not have a history of antitumor necrosis factor use.

    Juvenile rheumatoid arthritis (JRA), unlike rheumatoid arthritis of adulthood (RA), is a heterogenous disease comprising at least five subtypes that differ in clinical course and prognosis, and require different therapeutical approaches. As compared to RA, the production of local and systemic cytokines in JRA have not yet been as extensively investigated. In this article we review the available literature on cytokine expression in serum and synovial fluid in all five different subtypes of JRA. Even though the data are still fragmentary, the evidence so far suggests that the determination of serum cytokines yields relevant information as to clinical subtype and inflammatory activity of the disease. Furthermore, the cytokine data suggest that the pathogenesis of JRA may even by more heterogenous than defined by the clinical subtypes. Finally, future directions of research in this area are proposed, and-based on the latest results-arguments for (anti)cytokine therapies in JRA are critically discussed.

    Rheumatoid arthritis (RA) is a chronic systemic connective tissue disease. The development of comorbidities often occurs in the course of RA. One of them is osteoporosis, which has serious social and economic effects and may contribute to the increase in the degree of disability and premature death of the patient. Due to the young age in which RA disease occurs, densitometry (DXA) of the lumbar spine is the basic examination in osteoporosis diagnostics. In the course of RA, much more frequently than in healthy persons of the same age, osteoporotic fractures of vertebral bodies occur, which hinder a correct assessment in the DXA test. Rheumatoid arthritis patients often undergo computed tomography (CT) examination of the abdominal cavity for other medical indications than suspected spinal injury. Then, CT examination may also serve for the assessment of bone density, especially in patients with osteoporotic fractures. PMID:27407274

    An increased understanding in the pathophysiology of chronic inflammatory diseases, such as rheumatoid arthritis, reveals that the diseased tissue and the increased presence of macrophages and other overexpressed molecules within the tissue can be exploited to enhance the delivery of nanomedicine. Nanomedicine can passively accumulate into chronic inflammatory tissues via the enhanced permeability and retention phenomenon, or be surface conjugated with a ligand to actively bind to receptors overexpressed by cells within chronic inflammatory tissues, leading to increased efficacy and reduced systemic side-effects. This review highlights the research conducted over the past decade on using nanomedicine for potential treatment of rheumatoid arthritis and summarizes some of the major findings and promising opportunities on using nanomedicine to treat this prevalent and chronic disease.

    Juvenile arthritis is one of the most prevalent chronic diseases in the childhood period (ages 0 to 16 years). This disease was first defined in the first half of the 16th century. In the course of time, its differential diagnosis and characteristics have been determined, and it has been classified. Incidence and prevalence values are 10 to 20 in 100,000 and 56 to 113 in 100,000, respectively. Various factors are suggested for its underlying cause. Its denomination is also in dispute. Treatment of juvenile arthritis includes education, medical treatment, physical therapy, and occupational therapy. This article summarizes the objectives and methods of physical therapy and rehabilitation that are important parts of treatment.

    The foot and ankle are commonly involved in a range of arthritides that affect the joints, bones, and soft tissues. Accurate plain film interpretation can often aid the diagnosis and monitor disease progression and treatment response. Ultrasound and MRI afford superior depiction of the soft tissues, and advances over recent years have centered on early detection of synovitis, enabling earlier diagnosis and treatment. Advantages and disadvantages of the imaging techniques of radiography, multidetector computed tomography, ultrasound, and MRI are discussed, as is optimization of these modalities for the assessment of the anatomically complex joints of the foot and ankle. Diagnostic features enabling differentiation between rheumatoid arthritis, seronegative spondyloarthropathies, osteoarthritis, gout, crystal deposition disease, pigmented villonodular synovitis, Charcot arthropathy, septic arthritis, synovial osteochondromatosis, hemophilia, and reflex sympathetic dystrophy are also reviewed.

    The concept "treat to target" in rheumatology was first developed for rheumatoid arthritis. A similar attempt to develop such an approach for spondyloarthritis was unsuccessful because the assessment tools and target of therapy had not been developed. In psoriatic arthritis (PsA), composite indices to assess disease activity, disease state, and responsiveness have been developed and can be used as targets. There are a number of definitions for remission, but none are widely accepted. However, a state of minimal disease activity has been defined. There is evidence now that the treat-to-target approach is feasible, using the minimal disease activity state as a target and devising a tight control approach, which is superior to standard of care. Further work will determine the best target and the best approach to reach it.

    2015-01-01

    Given the varied therapeutic options available for the management of psoriatic arthritis (PsA), recommendations for the management of PsA have been developed by several expert groups. These recommendations deal mainly with pharmacological treatments. At the international level, 2 recommendations sets are available: these have been developed by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and by the European League against Rheumatism (EULAR). These recommendations were published in 2009 and in 2012, respectively; and updates of these recommendations are currently ongoing. The first sets of recommendations dealt with non-steroidal anti-inflammatory drugs, glucocorticoids, conventional synthetic disease modifying drugs and tumour necrosis factor inhibitors; the 2015 sets of recommendations also deal with new drugs with other mechanisms of action, namely ustekinumab, secukinumab and apremilast. In the present paper, we will review these management recommendations.

    Arthritic disorders are family of diseases that have existed since vertebrate life began. Their etiology is multifactorial with genetic, environmental, and gender factors driving chronic joint inflammation. Prolactin is a sexually dimorphic hormone in mammals that can act to both promote and ameliorate rheumatic diseases. It is found in all vertebrate groups where it exerts a wide diversity of actions. This review briefly addresses the presence and features of arthritic diseases in vertebrates, the effects of PRL on joint tissues and immune cells, and whether PRL actions could have contributed to the ubiquity of arthritis in nature. This comparative approach highlights the value of PRL as a biologically conserved factor influencing the development and progression of arthritis.

    121 patients with active rheumatoid arthritis, 91 of whom had proved intolerant of other nonsteroidal anti-inflammatory agents, were treated for a mean of 10 months with naproxen. A dosage of 250 mg twice daily produced sustained improvement in most of the standard clinical measurements. 28 patients complained of side effects, with a lower than expected incidence of gastrointestinal complaints and no drug-induced rash being recorded. 19 patients withdrew from the trial because of side effects, while a further 22 withdrew because the drug was ineffective. Naproxen is a useful drug for long-term use in patients with rheumatoid arthritis, including those who have proved intolerant of or experienced inadequate symptomatic relief from other nonsteriodal anti-inflammatory agents.

  3. Hormones and autoimmunity: animal models of arthritis.

    PubMed

    Wilder, R L

    1996-05-01

    Hormones, particularly those involved in the hypothalamic-pituitary-gonadal and -adrenal axes (HPG and HPA), play important roles in various animal models of autoimmunity such as systemic lupus erythematosus in mice and collagen-induced arthritis (CIA) in mice and rats, and the streptococcal cell wall, adjuvant and avridine arthritis models in rats. Intimately linked to the subject of hormones and autoimmunity are gender, sex chromosomes and age. The importance of these factors in the various animal models is emphasized in this chapter. Several major themes are apparent. First, oestrogens promote B-cell dependent immune-complex mediated disease (e.g. lupus nephritis) but suppress T-cell dependent pathology (CIA in mice and rats), and vice versa. Second, testosterone's effects are complicated and depend on species and disease model. In rats, testosterone suppresses both T-cell and B-cell immunity. In mice, the effects are complex and difficult to interpret, e.g. they tend to enhance CIA arthritis and suppress lupus. Sex chromosome/sex hormone interactions are clearly involved in generating these complicated effects. Third, studies in Lewis and Fischer F344 rats exemplify the importance of corticosteroids, corticotrophin releasing hormone and the HPA axis in the regulation of inflammation and the predisposition to autoimmune diseases. Fourth, the HPA axis is intimately linked to the HPG axis and is sexually dimorphic. Oestrogens stimulate higher corticosteroid responses in females. The animal model data have major implications for understanding autoimmunity in humans. In particular, adrenal and gonadal hormone deficiency is likely to facilitate T-cell dependent diseases like rheumatoid arthritis, while high oestrogen levels or effects, relative to testosterone, are likely to promote B-cell dependent immune-complex-mediated diseases such as lupus nephritis.

It was found that patients with JCA, and particularly those with the systemic form, show decreased plasma fibrinolytic activity and a marked increase in plasminogen activator inhibitor. Additionally, it was found that patients with systemic JCA, but not those with the polyarticular or pauciarticular form, have increased circulating levels of tissue-type plasminogen activator, and endothelial cell protein, suggesting possible endothelial cell participation in systemic JCA.

  8. Anti-enterobacteria antibodies in psoriatic arthritis.

    PubMed

    The occurrence of certain antibacterial antibodies was studied in the sera of 22 healthy donors (HD) and 66 patients with different diseases. The cases investigated included 22 rheumatoid arthritis (RA), 22 non-arthritic-psoriasis (NAP), and 22 psoriatic arthritis (PA) patients. A complement fixation test was used with Yersinia enterocolitica 0:3 type (YEC), Yersinia pseudotuberculosis (YPT), Campylobacter jejuni (CJ), and Campylobacter fetus (CF) antigens; the detection of anti-Chlamydia trachomatis (CT) antibodies was carried out using an immunoperoxidase colorimetric slide test that allowed the detection of isotypes of specific antibodies. It was found that the synthesis of anti-CF, CJ, YEC, and YPT antibodies in NAP patients does not differ significantly from that of the HD group; on the contrary, the antibody levels were statistically higher in PA than in the other disease groups or in the healthy controls, although only anti-CF antibodies seemed to significantly differentiate (p = 0.000003) the PA group from the others. Anti-CT IgA antibody titers were found to be significantly higher in the PA as well as in the RA groups when compared with the controls, while the antibody levels in NAP patients showed no clear-cut difference with respect to those of either the arthritic patients or the healthy controls. By showing that anti-enterobacterial antibodies are increased in PA but not in NAP patients, our data furnish additional support to the thesis of a pathogenic role of bacterial infections in psoriatic arthritis.

    Rheumatoid arthritis (RA) is a debilitating autoimmune disease of global prevalence. The disease is characterized by synovial inflammation leading to cartilage and bone damage. Most of the conventional drugs used for the treatment of RA have severe adverse reactions and are quite expensive. Over the years, increasing proportion of patients with RA and other immune disorders are resorting to complementary and alternative medicine (CAM) for their health needs. Natural plant products comprise one of the most popular CAM for inflammatory and immune disorders. These herbal CAM belong to diverse traditional systems of medicine, including traditional Chinese medicine, Kampo, and Ayurvedic medicine. In this paper, we have outlined the major immunological pathways involved in the induction and regulation of autoimmune arthritis and described various herbal CAM that can effectively modulate these immune pathways. Most of the information about the mechanisms of action of herbal products in the experimental models of RA is relevant to arthritis patients as well. The study of immunological pathways coupled with the emerging application of genomics and proteomics in CAM research is likely to provide novel insights into the mechanisms of action of different CAM modalities.

  10. Diagnosis and classification of juvenile idiopathic arthritis.

    Eisenstein, Eli M; Berkun, Yackov

    2014-01-01

    In recent years, it has become increasingly clear that the term Juvenile Idiopathic Arthritis (JIA) comprises not one disease but several. Moreover, recent studies strongly suggest that some of these clinico-pathophysiologic entities appear to cross current diagnostic categories. The ultimate goal of the JIA classification is to facilitate development of better, more specific therapy for different forms of disease though improved understanding of pathophysiology. The past two decades have witnessed significant advances in treatment and improved outcomes for many children with chronic arthritis. However, understanding of the basic biologic processes underlying these diseases remains far from complete. As a result, even the best biologic agents of today represent "halfway technologies". Because they do not treat fundamental biologic processes, they are inherently expensive, need to be given for a long time in order to ameliorate the adverse effects of chronic inflammation, and do not cure the disease. Pediatric rheumatology is now entering an era in which diagnostic categories may need to change to keep up with discovery. A more precise, biologically based classification is likely to contribute to development of more specific and improved treatments for the various forms of childhood arthritis. In this review, we discuss how genetic, gene expression, and immunologic findings have begun to influence how these diseases are understood and classified.

    Septic arthritis of the temporomandibular joint (TMJ) is a rare event that has only been reported a few dozen times worldwide. This case is remarkable for septic arthritis of the TMJ joint in an otherwise healthy male. Case Report: A 24-year-old male presented to the emergency department with periauricular swelling, erythema, fever, myalgia's and generalized joint pain. He had previously sought medical attention and was placed on ciprofloxacin. However, he developed facial swelling and a rash and had to discontinue the antibiotic. On physical exam the patient had a large swelling and tenderness in his left periauricular area, with erythema and deviation of the right mandible which limited his ability to open the mouth. A computed tomography showed mild asymmetric soft tissue swelling in the left pharyngeal region but did not show joint effusion. Subsequent magnetic resonance imaging did show effusion of the joint space. The effusion was drained, and the synovial fluid was submitted for gram stain, culture, and sensitivity. The cultures grew menthicillin sensitive Staphyloccocus Aureus. The patient was discharged to complete a two week course of intravenous (IV) Ceftriaxone and IV Vancomycin via home infusion. Conclusion: Septic Arthritis of the TMJ is a rare event with very specific clinical symptoms. Due to the low sensitivity of the computed tomography scan, magnetic resonance imaging should be considered when computed tomography scan is negative for TMJ effusion. PMID:26713295

    Hand radiographs provide a valuable index of disease in arthritis and other generalized diseases such as secondary hyperparathyroidism and osteoporosis. Measures such as cortical volume intercortical width average and periarticular demineralization provide diagnostic indicators for these diseases. However visual analysis of hand radiographs is not quantitative and is compromised by both interobserver and intraobserver variation. Automation of these measures would provide repeatable comparable quantities to assist in diagnosis and disease and therapy monitoring. The computer calculations to perform these measures are straightforward. The key problem is automatic segmentation of the hand anatomy that is recognizing the pixels that correspond to specific imaged bones and joints. Our approach incorporates computer-represented hand models in addition to more traditional image processing algorithms. We describe our techniques for using a combination of predictive models and image processing evidence to automatically fmd bone and tissue boundaries and identify specific bone and joints. 2. COMPUTING ARTHRITIS MEASURES Digital scanners and radiograph digitizers make the radiograph available as a data source for computer algorithms that analyze medical imagery. This is significant because radiographs comprise more than 80 of all medical imagery at this time and they are considerably quicker and less costly than other digital modalities such as CT and Mill. Quantitative measures from digital radiographs can aid physicians in diagnosis tracking disease progress and in therapy planning and evaluation. We have begun studying diagnostic measures in arthritis

  13. The conundrum of juvenile psoriatic arthritis.

    2015-01-01

    Juvenile psoriatic arthritis (JPsA) has provided paediatric rheumatologists with a controversial topic for many years. The principal area of contention centres on the discordance between its treatment as a single diagnostic category in current classification schemes and the demonstration of its heterogeneous nature. A further point of debate is the distinctiveness of JPsA as an entity. Owing to these uncertainties, the concept of JPsA has evolved over the years and there have been several changes in its definition and diagnostic criteria. Recently, strong evidence has been provided that the spectrum of JPsA include at least two distinct subgroups, one that has the same characteristics as early-onset ANA-positive JIA, and another that is part of the spectrum of spondyloarthropathies and resembles the forms of psoriatic arthritis in adults that belong to the same disease family. These findings call for a revision of the classification of childhood arthritis, that refutes the assumptions that children with JPsA constitute a single homogeneous population and that JPsA should be considered an individual disease entity.

    Psoriatic arthritis (PsA) is a chronic inflammatory disease of the joints that occurs in patients with psoriasis. The spectrum of PsA includes arthritis, dactylitis, enthesitis, axial involvement, and skin lesions. Non-biologic disease-modifying anti-rheumatic drugs (DMARDs) such as methotrexate and leflunomide, and biologic DMARDs such as tumor necrosis factor (TNF) antagonists and ustekinumab, have been used to treat PsA. Apremilast is a novel therapy that inhibits phosphodiesterase 4, increases intracellular cAMP levels, and modulates expression of inflammatory mediators in favor of anti-inflammatory activity. It decreases the pro-inflammatory cytokines TNF-α, IFN-γ, IL-17, and IL-23 and increases the anti-inflammatory cytokine IL-10 under certain conditions. One phase II and four phase III clinical trials as well as long-term extension studies showed significant and sustained clinical efficacy and an adequate safety profile for apremilast in patients with active psoriatic arthritis.

    Investigation findings are generalized based on quantitation of antibodies against the antigens of intestinal microorganisms of Enterobacteriaceae family conducted in 66 children with various joint disease using the enzyme-linked immunoassay (ELISA) methodology. High antibody titres were revealed in 77.1% juvenile rheumatoid arthritis cases and in 80% cases with chronic juvenile arthritis which was not defined nosologically. All the patients with reactive arthritis associated with intestinal infection showed high tension of immunity to all tested enterobacteriaceae antigens with cross reactions to them. Patients with reactive arthritis associated with oral infection, with Reiter's disease and other disorders exhibited high antibody titres at the same rate as in the control.

    Behcet’s disease (BD) with arthritis is often confused with seronegative arthritis (SNA) because of shared clinical symptoms and the lack of definitive biomarkers for BD. To investigate possible metabolic patterns and potential biomarkers of BD with arthritis, metabolomic profiling of synovial fluid (SF) from 6 patients with BD with arthritis and 18 patients with SNA was performed using gas chromatography/time-of-flight mass spectrometry in conjunction with univariate and multivariate statistical analyses. A total of 123 metabolites were identified from samples. Orthogonal partial least square-discriminant analysis showed clear discrimination between BD with arthritis and SNA. A set of 11 metabolites were identified as potential biomarkers for BD using variable importance for projection values and the Wilcoxon-Mann-Whitney test. Compared with SNA, BD with arthritis exhibited relatively high levels of glutamate, valine, citramalate, leucine, methionine sulfoxide, glycerate, phosphate, lysine, isoleucine, urea, and citrulline. There were two markers identified, elevated methionine sulfoxide and citrulline, that were associated with increased oxidative stress, providing a potential link to BD-associated neutrophil hyperactivity. Glutamate, citramalate, and valine were selected and validated as putative biomarkers for BD with arthritis (sensitivity, 100%; specificity, 61.1%). This is the first report to present potential biomarkers from SF for discriminating BD with arthritis from SNA. The metabolomics of SF may be helpful in searching for potential biomarkers and elucidating the clinicopathogenesis of BD with arthritis. PMID:26270538

    Using interleukin (IL)-6-deficient (IL-6(0/0) mice or wild-type mice, we investigated the controversial role of IL-6 in joint inflammation and cartilage pathology during zymosan-induced arthritis (ZIA). Monoarticular arthritis was elicited by injection of zymosan into the right knee joint cavity. Production of IL-1, tumor necrosis factor (TNF), IL-6, and nitric oxide by the inflamed knee was assessed in washouts of joint capsule specimens. Plasma corticosterone was measured using a radioimmunoassay. Proteoglycan synthesis was assessed using [35S]sulfate incorporation into patellas ex vivo. Joint swelling was quantified by joint uptake of circulating 99mTechnetium pertechnetate. Histology was taken to evaluate cellular infiltration and cartilage damage. Zymosan caused a rapid increase in articular IL-1, IL-6, TNF, and NO levels. Except for IL-6, the released amounts and time course of these mediators were comparable in the IL-6-deficient mice and the wild-type mice. Elevated plasma corticosterone levels were measured during the first day of arthritis in both strains. At day 2 of ZIA, joint inflammation (joint swelling and cell exudate) in IL-6-deficient mice was comparable with that in the wild-type mice. The marked suppression of chondrocyte proteoglycan synthesis and proteoglycan degradation were on the average higher in the IL-6-deficient mice. Together this resulted in a more pronounced proteoglycan depletion in the IL-6-deficient mice as compared with the wild-type mice during the first week of arthritis. Injection of recombinant IL-6 into the joint cavity corrected the IL-6 deficiency and significantly reduced cartilage destruction. Inflammation was more chronic in the wild-type mice, and these mice also showed a higher prevalence for osteophyte formation. In ZIA, IL-6 plays a dual role in connective tissue pathology, reducing proteoglycan loss in the acute phase and enhancing osteophyte formation in the chronic phase. The latter could be related to the more

    The aim of this study was to identify immunoreactive neuropeptide Y (NPY) and calcitonin gene-related peptide (CGRP) neurons in the autonomic and sensory ganglia, specifically neurons that innervate the rat temporomandibular joint (TMJ). A possible variation between the percentages of these neurons in acute and chronic phases of carrageenan-induced arthritis was examined. Retrograde neuronal tracing was combined with indirect immunofluorescence to identify NPY-immunoreactive (NPY-IR) and CGRP- immunoreactive (CGRP-IR) neurons that send nerve fibers to the normal and arthritic temporomandibular joint. In normal joints, NPY-IR neurons constitute 78±3%, 77±6% and 10±4% of double-labeled nucleated neuronal profile originated from the superior cervical, stellate and otic ganglia, respectively. These percentages in the sympathetic ganglia were significantly decreased in acute (58±2% for superior cervical ganglion and 58±8% for stellate ganglion) and chronic (60±2% for superior cervical ganglion and 59±15% for stellate ganglion) phases of arthritis, while in the otic ganglion these percentages were significantly increased to 19±5% and 13±3%, respectively. In the trigeminal ganglion, CGRP-IR neurons innervating the joint significantly increased from 31±3% in normal animals to 54±2% and 49±3% in the acute and chronic phases of arthritis, respectively. It can be concluded that NPY neurons that send nerve fibers to the rat temporomandibular joint are located mainly in the superior cervical, stellate and otic ganglia. Acute and chronic phases of carrageenan-induced arthritis lead to an increase in the percentage of NPY-IR parasympathetic and CGRP-IR sensory neurons and to a decrease in the percentage of NPY-IR sympathetic neurons related to TMJ innervation.

  19. K/BxN Serum-Transfer Arthritis as a Model for Human Inflammatory Arthritis.

    PubMed

    Christensen, Anne D; Haase, Claus; Cook, Andrew D; Hamilton, John A

    2016-01-01

    The K/BxN serum-transfer arthritis (STA) model is a murine model in which the immunological mechanisms occurring in rheumatoid arthritis (RA) and other arthritides can be studied. To induce K/BxN STA, serum from arthritic transgenic K/BxN mice is transferred to naive mice and manifestations of arthritis occur a few days later. The inflammatory response in the model is driven by autoantibodies against the ubiquitously expressed self-antigen, glucose-6-phosphate isomerase (G6PI), leading to the formation of immune complexes that drive the activation of different innate immune cells such as neutrophils, macrophages, and possibly mast cells. The pathogenesis further involves a range of immune mediators including cytokines, chemokines, complement factors, Toll-like receptors, Fc receptors, and integrins, as well as factors involved in pain and bone erosion. Hence, even though the K/BxN STA model mimics only the effector phase of RA, it still involves a wide range of relevant disease mediators. Additionally, as a murine model for arthritis, the K/BxN STA model has some obvious advantages. First, it has a rapid and robust onset of arthritis with 100% incidence in genetically identical animals. Second, it can be induced in a wide range of strain backgrounds and can therefore also be induced in gene-deficient strains to study the specific importance of disease mediators. Even though G6PI might not be an essential autoantigen, for example, in RA, the K/BxN STA model is a useful tool to understand how autoantibodies, in general, drive the progression of arthritis by interacting with downstream components of the innate immune system. Finally, the model has also proven useful as a model wherein arthritic pain can be studied. Taken together, these features make the K/BxN STA model a relevant one for RA, and it is a potentially valuable tool, especially for the preclinical screening of new therapeutic targets for RA and perhaps other forms of inflammatory arthritis.

    Highlights: •Sirt2 expression decreases in collagen-induced arthritis (CIA). •Sirt2 knockout aggravates severity of arthritis in mice with CIA. •Sirt2 knockout increases levels of pro-inflammatory factors in the serum. •Sirt2 deacetylates p65 and inhibits pro-inflammatory factors expression. •Sirt2 rescue abates severity of arthritis in mice with CIA. -- Abstract: Arthritis is a common autoimmune disease that is associated with progressive disability, systemic complications and early death. However, the underling mechanisms of arthritis are still unclear. Sirtuins are a NAD{sup +}-dependent class III deacetylase family, and regulate cellular stress, inflammation, genomic stability, carcinogenesis, and energy metabolism. Among the sirtuin family members, Sirt1 and Sirt6 are critically involved in the development of arthritis. It remains unknown whether other sirtuin family members participate in arthritis. Here in this study, we demonstrate that Sirt2 inhibits collagen-induced arthritis (CIA) using in vivo and in vitro evidence. The protein and mRNA levels of Sirt2 significantly decreased in joint tissues of mice with CIA. When immunized with collagen, Sirt2-KO mice showed aggravated severity of arthritis based on clinical scores, hind paw thickness, and radiological and molecular findings. Mechanically, Sirt2 deacetylated p65 subunit of nuclear factor-kappa B (NF-κB) at lysine 310, resulting in reduced expression of NF-κB-dependent genes, including interleukin 1β (IL-1β), IL-6, monocyte chemoattractant protein 1(MCP-1), RANTES, matrix metalloproteinase 9 (MMP-9) and MMP-13. Importantly, our rescue experiment showed that Sirt2 re-expression abated the severity of arthritis in Sirt2-KO mice. Those findings strongly indicate Sirt2 as a considerably inhibitor of the development of arthritis.

    Introduction: The calcific tendinitis is a common to happen around the shoulder, calcific tendinitis of tendons adjacent to the hip is not common like the shoulder. It can present either as acute hip pain and limitation of movement or chronic hip pain. We present two patients one with acute presentation and the other one chronic. Case Report: We present a case series of two patients with calcific tendinitis of the gluteus medius muscle. One patient a 37-year-old male presented with acute severe hip pain associated with a raised temperature, prompting concern about septic arthritis. The second patient presented with chronic hip pain. Calcification of the soft tissues adjacent to the greater trochanter was evident on plain radiographs in both patients. CT and MRI scans excluded septic or inflammatory arthritis in the patient with an acute presentation, the patient’s condition settled with analgesia and NSAIDs. Conclusion: An unusual combination of symptoms and finding mimicking septic arthritis should be considered in patients presenting with acute calcific tendinitis of the hip gluteus medius muscle.

    Lyme disease, caused by the spirochete Borrelia burgdorferi, is the most prevalent arthropod-borne illness in the United States and remains a clinical and social challenge. The spectrum of disease severity among infected patients suggests that host genetics contribute to pathogenic outcomes, particularly in patients who develop arthritis. Using a forward genetics approach, we identified the lysosomal enzyme β-glucuronidase (GUSB), a member of a large family of coregulated lysosomal enzymes, as a key regulator of Lyme-associated arthritis severity. Severely arthritic C3H mice possessed a naturally occurring hypomorphic allele, Gusbh. C57BL/6 mice congenic for the C3H Gusb allele were prone to increased Lyme-associated arthritis severity. Radiation chimera experiments revealed that resident joint cells drive arthritis susceptibility. C3H mice expressing WT Gusb as a transgene were protected from severe Lyme arthritis. Importantly, the Gusbh allele also exacerbated disease in a serum transfer model of rheumatoid arthritis. A known GUSB function is the prevention of lysosomal accumulation of glycosaminoglycans (GAGs). Development of Lyme and rheumatoid arthritis in Gusbh-expressing mice was associated with heightened accumulation of GAGs in joint tissue. We propose that GUSB modulates arthritis pathogenesis by preventing accumulation of proinflammatory GAGs within inflamed joint tissue, a trait that may be shared by other lysosomal exoglycosidases.

    Environmental factors contribute to development of autoimmune diseases. For instance, human autoimmune arthritis can associate with intestinal inflammation, cigarette smoking, periodontal disease, and various infections. The cellular and, molecular pathways whereby such remote challenges might precipitate arthritis or flares remain unclear. Here, we used a transfer model of self-reactive arthritis-inducing CD4(+) cells from KRNtg mice that, upon transfer, induce a very mild form of autoinflammatory arthritis in recipient animals. This model enabled us to identify external factors that greatly aggravated disease. We show that several distinct challenges precipitated full-blown arthritis, including intestinal inflammation through DSS-induced colitis, and bronchial stress through Influenza infection. Both triggers induced strong IL-17 expression primarily in self-reactive CD4(+) cells in lymph nodes draining the site of inflammation. Moreover, treatment of mice with IL-1β greatly exacerbated arthritis, while transfer of KRNtg CD4(+) cells lacking IL-1R significantly reduced disease and IL-17 expression. Thus, IL-1β enhances the autoaggressive potential of self-reactive CD4(+) cells, through increased Th17 differentiation, and this influences inflammatory events in the joints. We propose that diverse challenges that cause remote inflammation (lung infection or colitis, etc.) result in IL-1β-driven Th17 differentiation, and this precipitates arthritis in genetically susceptible individuals. Thus the etiology of autoimmune inflammatory arthritis likely relates to diverse triggers that converge to a common pathway involving IL-1β production and Th17 cell distribution. PMID:27427404

    For many decades two types of acute pancreatitis have been recognized: the edematous or interstitial and the hemorrhagic or necrotic. In most cases acute pancreatitis is associated with alcoholism or biliary tract disease. Elevated serum or urinary α-amylase is the most important finding in diagnosis. The presence of methemalbumin in serum and in peritoneal or pleural fluid supports the diagnosis of the hemorrhagic form of the disease in patients with a history and enzyme studies suggestive of pancreatitis. There is no characteristic clinical picture in acute pancreatitis, and its complications are legion. Pancreatic pseudocyst is probably the most common and pancreatic abscess is the most serious complication. The pathogenetic principle is autodigestion, but the precise sequence of biochemical events is unclear, especially the mode of trypsinogen activation and the role of lysosomal hydrolases. A host of metabolic derangements have been identified in acute pancreatitis, involving lipid, glucose, calcium and magnesium metabolism and changes of the blood clotting mechanism, to name but a few. Medical treatment includes intestinal decompression, analgesics, correction of hypovolemia and other supportive and protective measures. Surgical exploration is advisable in selected cases, when the diagnosis is in doubt, and is considered imperative in the presence of certain complications, especially pancreatic abscess.

    In this paper on the diagnosis and treatment of arthritis in horses, both degenerative arthritis and septic arthritis are considered. Diagnosis should be made on the combination of clinical examination together with the use of diagnostic aids such as radiology, intra-articular local anaesthesia and synovial fluid analysis. Intra-articular therapy appears to be the most effective in the treatment of degenerative arthritis. Excellent responses to therapy have been reported with corticosteroids, sodium hyaluronate, orgotein and synovial fluid transfer, where joints showed an absence of degenerative changes on radiographs. In septic arthritis, systemic treatment with the appropriate antibiotic, following bacterial culture and sensitivity testing, can produce good results if prompt diagnosis is made.

    Septic pyogenic arthritis of the acromioclavicular joint is a rare entity that occurs in immunosuppressed patients or those with discontinuity of defense barriers. There are only 15 cases described in the literature. The diagnosis is based on clinical features and the isolation of a microorganism in synovial fluid or blood cultures. The evidence of arthritis by imaging (MRI, ultrasound or scintigraphy) may be useful. Antibiotic treatment is the same as in septic arthritis in other locations. Staphylococcus aureus is the microorganism most frequently isolated. Our objective was to describe the clinical features, treatment and outcome of patients diagnosed with septic arthritis of the acromioclavicular joint at a Rheumatology Department. We developed a study with a retrospective design (1989-2012). The medical records of patients with septic arthritis were reviewed (101 patients). Those involving the acromioclavicular joint were selected (6 patients; 6%).

    Patients with rheumatoid arthritis are predisposed to systemic bone loss, and they are at an increased risk of fractures. Although there are similarities in the patient demographics between rheumatoid arthritis patients and the general population of osteoporosis patients, there are factors, particularly the use of glucocorticoids, which are specific to rheumatoid arthritis. These factors can lead to an increased risk of bone loss and fracture. Given that fractures are often very debilitating, especially in elderly patients, it is of paramount importance for the practicing rheumatologist to be aware of ways to reduce the risk of fracture in patients with rheumatoid arthritis. This review discusses currently available modalities for fracture risk assessment as well as pharmacologic and lifestyle interventions available to treat and prevent bone loss in rheumatoid arthritis patients.

    Systemic juvenile idiopathic arthritis is one of the common rheumatic diseases in childhood and characterized by spiking fever, evanescent skin rash, lymphadenopathy, hepatosplenomegaly, and serositis, in addition to arthritis. Children with systemic juvenile idiopathic arthritis often show growth retardation and developmental abnormality, as well as macrophage activation syndrome, a life-threatening complication. Overproduction of interleukin-6 is pathologically responsible for the systemic inflammatory manifestations and abnormal laboratory results with systemic juvenile idiopathic arthritis. Thus, tocilizumab, a humanized antihuman interleukin-6 receptor antibody, has been developed as a therapeutic agent for the disease. A series of clinical studies have demonstrated the excellent efficacy and safety of tocilizumab for patients with active disease. Tocilizumab was approved for systemic juvenile idiopathic arthritis in Japan in 2008 and in the European Union and the United States in 2011.

    The assessment of pain is of critical importance for mechanistic studies as well as for the validation of drug targets. This review will focus on knee joint pain associated with arthritis. Different animal models have been developed for the study of knee joint arthritis. Behavioral tests in animal models of knee joint arthritis typically measure knee joint pain rather indirectly. In recent years, however, progress has been made in the development of tests that actually evaluate the sensitivity of the knee joint in arthritis models. They include measurements of the knee extension angle struggle threshold, hind limb withdrawal reflex threshold of knee compression force, and vocalizations in response to stimulation of the knee. A discussion of pain assessment in humans with arthritis pain conditions concludes this review.

    Genetic discoveries in arthritis and their associated biological pathways spanning the innate and adaptive immune system demonstrate the strong association between susceptibility to arthritis and control of exogenous organisms. The canonical theory of the aetiology of immune-mediated arthritis and other immune-mediated diseases is that the introduction of exogenous antigenic stimuli to a genetically susceptible host sets up the environment for an abnormal immune response manifesting as disease. A disruption in host-microbe homeostasis driven by disease-associated genetic variants could ultimately provide the source of exogenous antigen triggering disease development. We discuss genetic variants impacting the innate and adaptive arms of the immune system and their relationship to microbial control and arthritic disease. We go on to consider the evidence for a relationship between HLA-B27, infection and arthritis, and then emerging evidence for an interaction between microbiota and rheumatoid arthritis.

    Mycoplasmas, including Ureaplasma and Mycoplasma species, are uncommon but important causes of septic arthritis, especially affecting immunosuppressed patients. Many of the reported cases have been associated with congenital immunodeficiency disorders, especially hypogammaglobulinemia. Mycoplasmas are difficult to grow in the laboratory, and these infections may be underdiagnosed using culture techniques. We report a case of a 21-year-old woman with juvenile idiopathic arthritis and hip arthroplasties treated with rituximab and adalimumab who developed urogenital infections and soft tissue abscesses followed by knee arthritis with negative routine cultures. Ureaplasma species was identified from synovial fluid on 2 separate occasions using a broad-range 16S ribosomal RNA gene polymerase chain reaction. Azithromycin led to rapid improvement in symptoms, but after completion of therapy, involvement of the hip prosthesis became apparent, and again, 16S rRNA gene polymerase chain reaction was positive for Ureaplasma species. The literature is reviewed with a discussion of risk factors for Mycoplasma septic arthritis, clinical presentation, methods of diagnosis, and treatment.

    Objective Capsaicin (CAP) and Resiniferatoxin (RTX) are vanilloid receptor agonists that can normalize Evoked Pain Scores (EPS) and Automated Dynamic Weight Bearing (ADWB) measures in murine acute inflammatory arthritis when given by intra-articular (IA) injection. To determine whether these vanilloid receptor agonists have benefit in Complete Freund’s Adjuvant (CFA) induced chronic inflammatory arthritis pain, we measured changes in ADWB and EPS in arthritic mice with and without treatment with IA CAP and RTX. Methods and materials Chronic inflammatory arthritis was produced by IA injection of 30 µl of Complete Freund’s Adjuvant (CFA) into the left knee of C57BL6 male mice 3 weeks prior to pain behavior testing. Mice were injected with either low or high dose IA RTX (10µl of 0.001 or 0.003%), or IA CAP (10 µL of 0.01%) 7 days prior to pain behavior testing. Results Chronic Inflammatory arthritis pain produced increased EPS and reduced ADWB measures for weight bearing in the affected limb of arthritic mice compared to naïve mice. ADWB measurements for time in CFA when compared with Naive were not significantly different, but suggested off-loading the arthritic limb to the normal limb. Treatment with IA CAP or RTX 7 days prior to pain behavior testing produced significant improvement in EPS but no improvement in ADWB measures. Neither IA CAP nor IA RTX had any impact on EPS or ADWB measurements in non-arthritic mice when given 7 days prior to pain behavioral testing. Conclusion Using ADWB and EPS, we quantified pain in a murine chronic inflammatory arthritis model. IA CFA caused a significant increase in EPS and decreased ADWB measures in the affected limb. Treatment with IA RTX and CAP produced significant improvement in EPS in mice with mono-articular inflammatory arthritis. IA vanilloid treatment produced no improvement in ADWB measurements for weight and for time.

    2013-11-01

    Arthritis is the most common cause of disability among U.S. adults and is particularly common among persons with multiple chronic conditions. In 2003, arthritis in the United States resulted in an estimated $128 billion in medical-care costs and lost earnings. To update previous U.S. estimates of the prevalence of doctor-diagnosed arthritis and arthritis-attributable activity limitation (AAAL), CDC analyzed 2010-2012 data from the National Health Interview Survey (NHIS). This report summarizes the results of that analysis, which found that 52.5 million (22.7%) of adults aged ≥18 years had self-reported doctor-diagnosed arthritis, and 22.7 million (9.8%, or 43.2% of those with arthritis) reported AAAL, matching and exceeding previous projected increases, respectively. Among persons with heart disease, diabetes, and obesity, the prevalences of doctor-diagnosed arthritis were 49.0%, 47.3%, and 31.2%, respectively; the prevalences of AAAL among persons with these specific conditions were 26.8%, 25.7%, and 15.2%, respectively. Greater use of evidence-based interventions, such as chronic disease self-management education and physical activity interventions that have been proven to reduce pain and improve quality-of-life among adults with chronic diseases might help reduce the personal and societal burden of arthritis.

    Rice body formation is a nonspecific response to chronic synovial inflammation associated with tuberculous arthritis, rheumatoid arthritis, juvenile rheumatoid arthritis, seronegative inflammatory arthritis, and even osteoarthritis. Such bodies were termed rice bodies because of their close resemblance to grains of polished white rice. We present a case report of a middle-aged woman with right shoulder subacromial/subdeltoid bursitis with giant rice body formation as her initial presentation of rheumatoid arthritis. Her right shoulder symptoms resolved after subacromial and subdeltoid bursectomy and removal of the rice bodies. She subsequently developed inflammatory arthritis of other joints, met the criteria for rheumatoid arthritis, and has been treated medically. PMID:23013846

    Rheumatoid arthritis (RA) is an inflammatory autoimmune disease with no known cure. Current strategies to treat RA, including methotrexate (MTX), target the later inflammatory stage of disease. Recently, we showed that inhibiting indoleamine-2,3-dioxygenase (IDO) with 1-methyl-tryptophan (1MT) targets autoantibodies and cytokines that drive the initiation of the autoimmune response. Therefore, we hypothesized that combining 1MT with MTX would target both the initiation and chronic inflammatory phases of the autoimmune response and be an effective co-therapeutic strategy for arthritis. To test this, we used K/BxN mice, a pre-clinical model of arthritis that develops joint-specific inflammation with many characteristics of human RA. Mice were treated with 1MT, MTX, alone or in combination, and followed for arthritis, autoantibodies, and inflammatory cytokines. Both 1MT and MTX were able to partially inhibit arthritis when used individually; however, combining MTX + 1MT was significantly more effective than either treatment alone at delaying the onset and alleviating the severity of joint inflammation. We went on to show that combination of MTX + 1MT did not lower inflammatory cytokine or autoantibody levels, nor could the synergistic co-therapeutic effect be reversed by the adenosine receptor antagonist theophylline or be mimicked by inhibition of polyamine synthesis. However, supplementation with folinic acid did reverse the synergistic co-therapeutic effect, demonstrating that, in the K/BxN model, MTX synergizes with 1MT by blocking folate metabolism. These data suggest that pharmacological inhibition of IDO with 1MT is a potential candidate for use in combination with MTX to increase its efficacy in the treatment of RA. PMID:24798341

    Introduction Tuberculosis remains a major public health problem in developing countries. Diagnosing extrapulmonary tuberculosis can be difficult, as it requires a higher index of suspicion than primary tuberculosis. Extrapulmonary tuberculosis may mimic malignancies and many other diseases, so it should be included in the differential diagnosis. Here, we present a case of extrapulmonary tuberculosis associated with Pott’s disease and hip arthritis in a patient who recovered after 12 months of antituberculosis therapy. Case Presentation A 16-year-old girl presented to the outpatient otolaryngology clinic with painless swelling of the neck, and to the physical medicine and rehabilitation clinic with complaints of hip and low back pain that mimicked spondyloarthropathy. She was eventually referred to the outpatient pediatric clinic. Her acute-phase reactants were high, and hilar lymphadenopathy was evident on chest x-ray. On computerized tomography, a Pott’s abscess involving the T8, T9, and T10 vertebrae was suspected. Magnetic resonance imaging of the dorsal vertebrae and hip was performed, and a Pott’s abscess and hip tuberculous arthritis were confirmed. The patient had been exposed to tuberculosis 10 years earlier, and her purified protein derivative (PPD) test was 16 mm. After antituberculosis treatment, our patient recovered and the Pott’s disease and hip tuberculous arthritis regressed. Conclusions Extrapulmonary tuberculosis may mimic many other diseases, so it should be kept in mind in the differential diagnosis. It is essential to diagnose osteoarticular tuberculosis early, as late diagnosis or inadequate treatment may cause permanent disability. PMID:27660720

  9. Odontoid upward migration in rheumatoid arthritis. An analysis of 45 patients with "cranial settling".

    Lack of correlation between the severity of rheumatoid subluxation of the upper cervical vertebrae and supposed absence of neurological damage has led to the erroneous supposition that this finding is innocuous. Incomplete autopsy studies in rheumatoid arthritis have failed to recognize the cause of death, despite previously proven dramatic occipito-atlanto-axial dislocations. The most feared entity of rheumatoid basilar invagination, namely "cranial settling," is poorly understood. Between 1978 and 1984, the authors treated 45 rheumatoid arthritis patients who were symptomatic with "cranial settling." This consisted of vertical odontoid penetration through the foramen magnum (9 to 33 mm), occipito-atlanto-axial dislocation, lateral atlantal mass erosion, downward telescoping of the anterior arch of C-1 on the axis, and rostral rotation of the posterior arch of C-1 producing ventral and dorsal cervicomedullary junction compromise. Cervicomedullary junction dysfunction has mistakenly been called "entrapment neuropathy," "progression of disease," or "vasculitis." Occipital pain occurred in all 45 patients, myelopathy in 36, blackout spells in 24, brain-stem signs in 17, and lower cranial nerve palsies in 10. Four patients had prior tracheostomies. Four previously asymptomatic patients with "cranial settling" presented acutely quadriplegic. The factors governing treatment were reducibility and direction of encroachment determined by skeletal traction and myelotomography. Transoral odontoidectomy was performed in seven patients with irreducible pathology. All patients underwent occipitocervical bone fusion (with C-1 decompression if needed) and acrylic fixation. Improvement occurred during traction, implying that compression might be the etiology for the neurological signs. There were no complications. Thus, "cranial settling" is a frequent complication of rheumatoid arthritis; although it is poorly recognized, it has serious implications and is treatable. PMID:4032013

    The in vivo role of phagocytic synovial lining cells (SLC) was studied in acute experimental arthritis in the mouse. SLCs were selectively depleted by injecting liposomes encapsulating the drug dichloromethylene diphosphonate (CL2MDP, Clodronate). Optimal depletion of phagocytic lining cells occurred 7 days after CL2MDP liposome injection. Eliciting an immune complex-mediated arthritis in SLC-depleted knee joints largely prevented inflammation if compared to control arthritic knee joints. Joint swelling and influx of inflammatory cells into the joint cavity was markedly diminished. Cartilage damage, in this model related to influx of inflammatory cells, was significantly decreased. Reduced influx of inflammatory cells (mainly polymorphonuclear neutrophils) was correlated to a decreased production of chemotactic factors as measured in washouts of arthritic joints in a two-compartment Transwell system. Interleukin-1-driven chemotactic factors seem to be involved. Interleukin-1 levels were significantly lowered in SLC-depleted arthritic knee joints as compared to controls. Injection of recombinant murine interleukin-1 in SLC-depleted knee joints caused less influx of inflammatory cells as compared to injection into control knee joints. A specific damage of CL2MDP liposome treatment to synovial blood vessels was excluded as intraarticular injection of human recombinant C5a in lining-depleted knee joints showed similar influx of inflammatory cells if compared to human recombinant C5a injection in control knee joints. This study indicates that in immune complex-mediated arthritis, phagocytic lining cells regulate the onset of the inflammatory response. Images Figure 2 Figure 3 Figure 6 Figure 8 PMID:8214013

    The "Bermuda triangle" of genetics, environment and autoimmunity is involved in the pathogenesis of rheumatoid arthritis (RA). Various aspects of genetic contribution to the etiology, pathogenesis and outcome of RA are discussed in this review. The heritability of RA has been estimated to be about 60 %, while the contribution of HLA to heritability has been estimated to be 11-37 %. Apart from known shared epitope (SE) alleles, such as HLA-DRB1*01 and DRB1*04, other HLA alleles, such as HLA-DRB1*13 and DRB1*15 have been linked to RA susceptibility. A novel SE classification divides SE alleles into S1, S2, S3P and S3D groups, where primarily S2 and S3P groups have been associated with predisposition to seropositive RA. The most relevant non-HLA gene single nucleotide polymorphisms (SNPs) associated with RA include PTPN22, IL23R, TRAF1, CTLA4, IRF5, STAT4, CCR6, PADI4. Large genome-wide association studies (GWAS) have identified more than 30 loci involved in RA pathogenesis. HLA and some non-HLA genes may differentiate between anti-citrullinated protein antibody (ACPA) seropositive and seronegative RA. Genetic susceptibility has also been associated with environmental factors, primarily smoking. Some GWAS studies carried out in rodent models of arthritis have confirmed the role of human genes. For example, in the collagen-induced (CIA) and proteoglycan-induced arthritis (PgIA) models, two important loci - Pgia26/Cia5 and Pgia2/Cia2/Cia3, corresponding the human PTPN22/CD2 and TRAF1/C5 loci, respectively - have been identified. Finally, pharmacogenomics identified SNPs or multiple genetic signatures that may be associated with responses to traditional disease-modifying drugs and biologics. PMID:23288628

    Three horses were diagnosed as having monarticular septic arthritis due to Staphylococcus aureus on the basis of culture of articular cartilage, synovial membrane and/or synovial fluid. The organisms were all well recognised human phage types and in two cases demonstrated beta-lactamase (penicillinase) activity. Details of case histories are presented and the bacteriological techniques and antibiotic management with cloxacillin, methicillin and penicillin discussed. Following treatment, sterile cultures of synovial fluid were achieved in all cases, but in two horses the infections resulted in degenerative articular changes. This necessitated arthrodesis of the fetlock joint in one case.

    The incidence of infection by Mycobacterium marinum is rising, mainly due to the increasing popularity of home aquariums. The infection typically manifests as skin lesions, with septic arthritis being a rare presentation form. The disease is difficult to diagnose even when there is a high clinical suspicion, as culture in specific media may not yield positive findings. Thus, establishment of appropriate treatment is often delayed. Synovectomy, capsular thinning, and joint drainage together with prolonged, combined antibiotic therapy may be needed to cure the infection.

    Both Rheumatoid Arthritis (RA) and Ankylosing Spondylitis (AS) are chronic, inflammatory systemic diseases. RA predominantly manifests itself in the peripheral joints, whereas AS most prominently in the spine. As time progresses the roles of active and physical therapy become increasingly important. The aims of intensive and dynamic exercise for patients with RA and AS are formulated following the ICIDH-2. Thus, the aims are a direct equation of body function, activities and participation. The benefits of exercise therapy are increased joint mobility, increased muscle strength, improved functional ability and better cardiorespiratory function without incurring a flare of the disease.

It was found that patients with JCA, and particularly those with the systemic form, show decreased plasma fibrinolytic activity and a marked increase in plasminogen activator inhibitor. Additionally, it was found that patients with systemic JCA, but not those with the polyarticular or pauciarticular form, have increased circulating levels of tissue-type plasminogen activator, and endothelial cell protein, suggesting possible endothelial cell participation in systemic JCA.

    Cellulosimicrobium cellulans has been reported as a rare cause of human pathogenesis. Infections mainly occur in immunocompromised patients and very often are associated with a foreign body. We report the first case of septic arthritis caused by C. cellulans in an immunocompetent patient. Our patient suffered a penetrating palm tree thorn injury to his left knee 8 weeks before admission. Although no foreign objects were found, they were suspected because previous reports suggest a frequent association with this microorganism, and open debridament was performed. Removal of foreign bodies related to this organism must be considered a high-priority treatment in these patients to achieve a complete recovery. PMID:21998421

    Intrahepatic hemorrhage is a serious and life-threatening complication in liver disease. We describe a patient who had two episodes of intrahepatic hemorrhage after having malignant rheumatoid arthritis for 8 yr. Abdominal CT scans revealed a large intrahepatic, subcapsular hematoma. Arteriography demonstrated irregularity, caliber change, and pseudoaneurysms of the right hepatic artery, suggesting vasculitis as a cause of the bleeding. The hemorrhage was first treated with transcatheter arterial embolization, which failed to exert long term control, but arterial infusion of a large dose of prednisolone when the hemorrhage appeared was successful in managing it.

    A 2-year-old girl was treated with gold salts for juvenile rheumatoid arthritis. Treatment had to be discontinued when persistent proteinuria was detected. As this case report indicates, close monitoring of the urine is mandatory during treatment with gold salts to detect early signs of toxicity: hematuria followed by casts and then proteinuria as therapy is continued. Histologic examination with electron microscopy will help to differentiate the different forms of gold toxicity. When the findings are consistent with gold-induced renal involvement, therapy should be discontinued. The gold nephropathy usually resolves in time, with no permanent renal damage.

    The incidence of infection by Mycobacterium marinum is rising, mainly due to the increasing popularity of home aquariums. The infection typically manifests as skin lesions, with septic arthritis being a rare presentation form. The disease is difficult to diagnose even when there is a high clinical suspicion, as culture in specific media may not yield positive findings. Thus, establishment of appropriate treatment is often delayed. Synovectomy, capsular thinning, and joint drainage together with prolonged, combined antibiotic therapy may be needed to cure the infection. PMID:26511731

    Qingfu Guanjieshu (QFGJS) is an herbal preparation for treating rheumatoid arthritis (RA). Previous studies revealed that QFGJS significantly inhibited experimental arthritis and acute inflammation, accompanied by reduction of proinflammatory cytokines and elevation of anti-inflammatory cytokines. This study aims to identify the targeted proteins and predict the proteomic network associated with the drug action of QFGJS by using 2D gel and MALDI-TOF-MS/MS techniques. Thirty female Wistar rats were evenly grouped as normal and vehicle- and QFGJS-treated CIA rats. The antiarthritic effect of QFGJS was examined with a 19-day treatment course, and the knee synovial tissues of animals from each group were obtained for 2D gel and MALDI-TOF-MS/MS analysis. Results showed that QFGJS significantly ameliorated collagen II-induced arthritis when administrated at 2.8 g/kg body weight for 19 days. 2D gel image analysis revealed 89 differentially expressed proteins in the synovial tissues among the normal and vehicle- and QFGJS-treated CIA rats from over 1000 proteins of which 63 proteins were identified by MALDI-TOF-MS/MS analysis, and 32 proteins were included for classification of functions using Gene Ontology (GO) method. Finally, 14 proteins were analyzed using bioinformatics, and a predicted proteomic network related to the anti-arthritic effect of QFGJS was established, and Pgk1 plays a central role. PMID:23781264

    Psoriasis is a polygenic, inflammatory and progressive disease, characterized by an abnormal differentiation and hyperproliferation of keratinocytes, associated with impaired immunologic activation and systemic disorders, while psoriatic arthritis is a chronic inflammatory articular disease. Pathophysiology of psoriasis comprises a dysfunction of the immune system cells with an interactive network between cells and cytokines supporting the initiation and perpetuation of disease and leading to inflammation of skin, enthesis and joints. Recent studies have shown an important role of systemic inflammation in the development of atherosclerosis. Corroborating these findings, patients with severe Psoriasis have marked incidence of psoriatic arthritis, cardiovascular diseases, hypertension, dyslipidemia, obesity and diabetes mellitus, showing an increased risk for acute myocardial infarction, which suggests that the condition is not restricted to the skin. Nuclear receptors are ligand-dependent transcription factors, whose activation affects genes that control vital processes. Among them the peroxisome proliferator-activated receptor is responsible for establishing the relationship between lipids, metabolic diseases and innate immunity. In the skin, peroxisome proliferator-activated receptors have an important effect in keratinocyte homeostasis, suggesting a role in diseases such as psoriasis. The peroxisome proliferator-activated receptors agonists represent a relevant source of research in the treatment of skin conditions, however more clinical studies are needed to define the potential response of these drugs in patients with psoriasis and psoriatic arthritis.

    The presentation of acute vertigo may represent both a common benign disorder or a life threatening but rare one. Familiarity with the common peripheral vestibular disorders will allow the clinician to rapidly “rule-in” a benign disorder and recognize when further testing is required. Key features of vertigo required to make an accurate diagnosis are duration, chronicity, associated symptoms, and triggers. Bedside tests that are critical to the diagnosis of acute vertigo include the Dix-Hallpike maneuver and canalith repositioning manuever, occlusive ophthalmoscopy, and the head impulse test. The goal of this review is to provide the clinician with the clinical and pathophysiologic background of the most common disorders that present with vertigo to develop a logical differential diagnosis and management plan.

  5. Interleukin 1 or tumor necrosis factor-alpha: which is the real target in rheumatoid arthritis?

    Much debate has focused on the relative importance of interleukin 1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha) in the pathophysiology of rheumatoid arthritis (RA). The production of these cytokines by synovial macrophages is tightly regulated by cell-cell contact with T cells. During this contact, several surface molecules are implicated in contact mediated cytokine production, including CD40 ligand, CD11b/c, and CD69. Apolipoprotein A-I, an acute phase reactant (APR) that declines during systemic inflammation (reverse APR), inhibits cytokine production by interfering in the T cell-monocyte interaction. Although the effects of IL-1 and TNF-alpha overlap, they have somewhat differing roles in RA on the basis of evidence from several animal models. TNF-alpha appears to play a more important role in triggering events leading to inflammation both locally and systemically, whereas IL-1 is more involved at the local level in processes leading to cartilage and bone destruction and in impeding cartilage repair. However, IL-1 and TNF-alpha strongly synergize in numerous biological functions, both in vitro and in vivo. Blockade of IL-1 and TNF-alpha simultaneously provides favorable effects in collagen and adjuvant induced arthritis, illustrating the importance of both cytokines.

    Vitis thunbergii Sieb. et Zucc. var. taiwaniana Lu (VT) is an indigenous plant in Taiwan that is traditionally used for promoting joint health. In this study, we used in vitro primary human chondrocytes (PHCs) and two in vivo animal models to evaluate the anti-inflammatory effects of VT on arthritis. Results showed that the water extract of the stems and roots from VT (VT-SR) was rich in flavones and phenols with 1.1 mg/g of resveratrol, 6.7 mg/g of hopeaphenol, and 5.1 mg/g of (+)-ɛ-viniferin. VT-SR significantly scavenged DPPH radicals and inhibited prostaglandin E2 (PGE2) production in lipopolysaccharide (LPS)-induced PHCs without exhibiting significant cytotoxicity. In in vivo models, the VT-SR (500 mg/kg) significantly decreased serum PGE2 and knee 2-(18)F-fluoro-2-deoxy-D-glucose ((18)F-FDG) levels in LPS-induced acute inflammatory arthritis in rabbits. In addition, dietary supplementation with VT-SR for 28 days significantly alleviated type II collagenase-induced rat osteoarthritis with improvements in weight bearing and range of motion tests. In conclusion, our results suggest that the VT-SR is a good candidate for developing dietary supplements to prevent joint deterioration and inhibit inflammation. PMID:24720858

    Four patients with refractory rheumatoid arthritis were treated with total body irradiation administered in two sittings, 300 to 400 rads to each half of the body. All four patients had taken antimetabolites prior to receiving total body irradiation, and two continued to use them after total body irradiation. Two patients had taken alkylating agents before, and one had used them after total body irradiation. All patients showed clinical improvement. However, in two patients myeloproliferative disorders developed: a myelodysplastic preleukemia at 40 months after total body irradiation in one and acute myelogenous leukemia at 25 months in the other. Total body irradiation differs from total nodal irradiation in the total dose of irradiation (300 to 400 rads versus 2,000 to 3,000), and in the duration of the therapy (two sittings versus treatment over several weeks to months). Furthermore, the patients in the total body irradiation study frequently used cytotoxic drugs before and/or after irradiation, whereas in one total nodal irradiation study, azathioprine (2 mg/kg per day or less) was permitted, but no other cytotoxic agents were allowed. Rheumatologists may therefore face a binding decision when deciding to treat a patient with rheumatoid arthritis with either a cytotoxic drug or irradiation.

    It is well known that patients suffering from rheumatoid arthritis have a reduced muscular function. The positive effect of physical training on rheumatic patients has been shown. In this study the effect of exercise therapy performed in a heated swimming pool has been evaluated for eight patients in a non-acute stage of rheumatoid arthritis. The median pre-treatment maximal isometric and isokinetic quadriceps strength was 88 Nm (44-146) and 99 Nm (62-149) respectively, which was 61% and 70% of that found in a control group of healthy persons. After 2 months exercise therapy the median maximal isometric and isokinetic quadriceps strength increased by 38% and 16% compared to the pre-treatment value (p less than 0.02 and p less than 0.05). All patients, except one who developed cardiac arrhythmia during the second test, accomplished a submaximal bicycle test (a.m. Astrand). An increase in the aerobic capacity was observed in all patients after the training period.

    An 83-year-old female patient with rheumatoid arthritis and hypertension presented to the emergency department with fever and chills of 1 day duration. On examination, temperature was 100.9 F, heart rate 111/min and she had orthostatic hypotension. Laboratory tests showed elevated blood urea nitrogen and white cell count. The patient underwent treatment for symptomatic urinary tract infection and while her fever and leucocytosis resolved, tachycardia persisted. An EKG done showed T inversions in leads II, III, arteriovenous fistula, V2 and V3. Troponin-I was elevated. Nuclear stress test revealed apical wall motion abnormality confirming myocardial infarction. Ewing's tests were carried out at bedside and these diagnosed severe autonomic neuropathy. Rheumatoid arthritis can cause cardiac autonomic neuropathy from chronic inflammation. This case entails the importance of assessing and detecting cardiac autonomic neuropathy in chronic inflammatory conditions, and the need to be cautious of acute coronary events in these patients, even for minimal or no symptoms.

    Diarrhea, defined as three or more loose or watery stools per day, represents a frequent problem in outpatients as well as inpatients. As most of the patients with acute diarrhea show a self-limiting disease course, the main challenge for the physician is to discriminate patients for whom symptomatic therapy is sufficient from those with severe disease course and threatening complications. This review aims to provide a practical guidance for such decisions.

    2009-05-01

    The effects of pine pollen extract (PE) on Freund's complete adjuvant (FCA)-induced arthritis and collagen-induced arthritis (CIA) were investigated. The oral administration of PE (100 and 200 mg/kg per day) for 21 days after subcutaneous immunization with FCA, significantly reduced hindpaw swelling and the production of inflammatory cytokines (TNF-alpha, IL-1beta and IL-6) compared with the FCA-induced arthritis group. Treatment with the PE (100 mg/kg) also decreased the serum levels of LDL-cholesterol and increased HDL-cholesterol contents compared with those of the arthritis group. Since CIA is a model of some types of human autoimmune rheumatoid arthritis (RA), the study examined whether PE is efficacious against CIA in mice and investigated the possible antioxidant potential of PE on CIA. Arthritis in DBA/1J mice was induced by subcutaneous immunization with bovine type II collagen. PE (100 and 200 mg/kg) was orally administered once daily for 49 days after initial immunization with type II collagen. The arthritis score and paw edema were markedly suppressed in the groups treated with PE. Moreover, administration of PE (100 mg/kg) for 49 days reduced the serum levels of rheumatoid factor, anti-type II collagen antibody, TNF-alpha, IL-1beta, IL-6, protein carbonyl, advanced glycation endproducts, malondialdehyde and LDL-cholesterol compared with that of CIA mice. These results suggest that the pine pollen might be beneficial in the treatment of chronic inflammatory disorders.

    The magnetic resonance (MR) imaging findings of foals with infectious and noninfectious arthritis are described. Six foals with infectious arthritis and three foals with noninfectious arthritis were grouped based on synovial fluid analysis results and examined with radiography and MR imaging. Four out of six foals with infectious arthritis had osseous lesions in MR images indicative of osteomyelitis and only 4/19 lesions were detected on digital radiographs. The three foals with noninfectious arthritis had no osseous lesions in MR images or radiographically. Of the six joints that had osseous lesions detected with MR imaging, three had at least one lytic lesion detected radiographically. Osseous lesions in the epiphysis, metaphysis, and physis appeared in MR images as T2W, short tau inversion recovery, and proton density hyperintense foci with a hypointense halo. The same lesions appeared hyperintense in the 3D RSSG water excitation pulse sequence but lacked a surrounding hypointense halo. Most joints of foals with infectious arthritis had heterogenous signals within the synovial fluid whereas all of the nonseptic joints had homogenous synovial fluid signals. MR imaging appears to be better than radiography in the detection of osseous lesions in foals diagnosed with infectious arthritis and may be a valuable screening test for the presence of osteomyelitis.

    Managing pain from chronic conditions, such as, but not limited to, osteoarthritis and rheumatoid arthritis, requires the clinician to balance the need for effective analgesia against safety risks associated with analgesic agents. Osteoarthritis and rheumatoid arthritis pain is incompletely understood but involves both nociceptive and non-nociceptive mechanisms, including neuropathic mechanisms. Prevailing guidelines for arthritis-related pain do not differentiate between nociceptive and non-nociceptive pain, sometimes leading to recommendations that do not fully address the nature of pain. NSAIDs are effective in treating the nociceptive arthritis-related pain. However, safety concerns of NSAIDs may cause clinicians to undertreat arthritis-related pain. In this context, combination therapy may be more appropriate to manage the different pain mechanisms involved. A panel convened in November 2010 found that among the currently recommended analgesic products for arthritis-related pain, fixed-low-dose combination products hold promise for pain control because such products allow lower doses of individual agents resulting in decreased toxicity and acceptable efficacy due to synergy between the individual drugs. Better evidence and recommendations are required to improve treatment of chronic arthritis-related pain. PMID:23264838

    Objective. The aim of the study was to describe echocardiographic abnormalities in patients with rheumatoid arthritis, concurrent systemic comorbidities, rheumatologic clinical activity, serologic markers of rheumatoid arthritis, and inflammatory activity. Methods. In an observational, cross-sectional study, rheumatoid arthritis outpatients were included (n = 105). Conventional transthoracic echocardiographic variables were compared between patients with arthritis and non-RA controls (n = 41). For rheumatoid arthritis patients, articular activity and rheumatologic and inflammatory markers were obtained. Results. Ventricular dysfunction was found in 54.3% of the population: systolic (18.1%), diastolic (32.4%), and/or right (24.8%), with lower ejection fraction (P < 0.0001). Pulmonary hypertension was found in 46.9%. Other echocardiographic findings included increased left atrial diameter (P = 0.01), aortic diameter (P = 0.01), ventricular septum (P = 0.01), left ventricular posterior wall (P = 0.013), and right ventricular (P = 0.01) and atrial diameters compared to control subjects. Rheumatoid factor and anti-CCP antibodies levels were significantly elevated in cases with ventricular dysfunction. Angina and myocardial infarction, diabetes, and dyslipidemia were the main risk factors for ventricular dysfunction. Conclusions. Ventricular dysfunction is common in rheumatoid arthritis and associated with longer disease duration and increased serologic markers of rheumatoid arthritis. Screening for cardiac abnormalities should be considered in this kind of patients.

    Arthritis is a frequent complication of infection in humans with Borrelia burgdorferi. Weeks to months following the onset of Lyme borreliosis, a histopathological reaction characteristic of synovitis including bone, joint, muscle, or tendon pain may occur. A subpopulation of patients may progress to a chronic, debilitating arthritis months to years after infection which has been classified as severe destructive Lyme arthritis. This arthritis involves focal bone erosion and destruction of articular cartilage. Hamsters and mice are animal models that have been utilized to study articular manifestations of Lyme borreliosis. Infection of immunocompetent LSH hamsters or C3H mice results in a transient synovitis. However, severe destructive Lyme arthritis can be induced by infecting irradiated hamsters or mice and immunocompetent Borrelia-vaccinated hamsters, mice, and interferon-gamma- (IFN-γ-) deficient mice with viable B. burgdorferi. The hamster model of severe destructive Lyme arthritis facilitates easy assessment of Lyme borreliosis vaccine preparations for deleterious effects while murine models of severe destructive Lyme arthritis allow for investigation of mechanisms of immunopathology.

    IL-23 is the key cytokine that induces the expansion of Th17 cells. It is composed of p19 and p40 subunits of IL-12. The p40 subunit binds competitively to the receptor of IL-23 and blocks its activity. Our aim was to assess the preventive and therapeutic effect of the IL-12p40 homodimer (p40)2 subunit in autoimmune arthritis animal models. In the current study, using IL-1R antagonist-knockout mice and a collagen-induced arthritis model, we investigated the suppressive effect of (p40)2 on inflammatory arthritis. We demonstrated that the recombinant adenovirus-expressing mouse (p40)2 model prevented the development of arthritis when given before the onset of arthritis. It also decreased the arthritis index and joint erosions in the mouse model if transferred after arthritis was established. (p40)2 inhibited the production of inflammatory cytokines and Ag-specific T cell proliferation. It also induced CD4(+)CD25(+)Foxp3 regulatory T (Treg) cells in vitro and in vivo, whereas the generation of retinoic acid receptor-related organ receptor γt and Th17 cells was suppressed. The induction of Treg cells and the suppression of Th17 cells were mediated via activated STAT5 and suppressed STAT3. Our data suggest that (p40)2 suppressed inflammatory arthritis successfully. This could be a useful therapeutic approach in autoimmune arthritis to regulate the Th17/Treg balance and IL-23 signaling. PMID:26324771

    Recent studies of rheumatoid arthritis worldwide suggest that prevalence of arthritis is higher in Europe and North America than in developing countries. Prevalence data for major arthritis disorders have been compiled in West for several decades, but figures from the third world are just emerging. A coordinated effort by WHO and ILAR (International League Against Rheumatism) has resulted in collecting data for countries like Philippines, China, Malaysia, Indonesia, and rural South Africa but the information about prevalence of arthritis in India and Pakistan is scarce. Since both countries, i.e., India and Pakistan, share some ethnic identity, we reviewed published literature to examine the prevalence of arthritis in these countries. Medline and Pubmed were searched for suitable articles about arthritis from 1980 and onwards. Findings from these articles were reviewed and summarized. The prevalence, clinical features, and laboratory findings of rheumatoid arthritis are compiled for both India and Pakistan. Data collected from these two countries were compared with each other, and some of the characteristics of the disease were compared with Europe and North America. It is found to be quite similar to developed countries. Additionally, juvenile rheumatoid arthritis is of different variety than reported in West. It is more of polyarticular onset type while in West pauciarticular predominates. Additionally, in systemic onset, JRA uveitis and ANA are common finding in developed countries; on the other hand, they are hardly seen in this region. Although the prevalence of arthritis in Pakistan and India is similar to Western countries, there are inherent differences (clinical features, laboratory findings) in the presentation of disease. The major strength of the study is that it is the first to pool reports to provide an estimate of the disease in the Indian subcontinent. Scarcity of data is one of the major limitations.

    Aim To test the hypothesis that rheumatoid arthritis influenced levels of salivary biomarkers of periodontal disease. Methods Medical assessments, periodontal examinations, and pain ratings were obtained from 35 rheumatoid arthritis, 35 chronic periodontitis and 35 age and gender-matched healthy controls in a cross-sectional, case-controlled study. Unstimulated whole saliva samples were analyzed for interleukin-1β (IL-1β), matrix-metalloproteinase-8 (MMP-8) and tumor necrosis factor-α (TNF)-α concentrations. Results The arthritis and healthy groups had significantly less oral disease than the periodontitis group (p<0.0001), with the arthritis group having significantly more sites bleeding on probing (BOP) than matched controls (p=0.012). Salivary levels of MMP-8 and IL-1β were significantly elevated in the periodontal disease group (p≤0.002), and IL-1β was the only biomarker with significantly higher levels in the arthritis group compared with controls (p=0.002). Arthritis patients receiving anti-TNF-α antibody therapy had significantly lower IL-1β and TNF-α levels compared with arthritis patients not on anti-TNF-α therapy (p=0.016, p=0.024) and healthy controls (p<0.001, p=0.011), respectively. Conclusion Rheumatoid arthritis patients have higher levels of periodontal inflammation than healthy controls, ie. increased BOP. Systemic inflammation appears to influence levels of select salivary biomarkers of periodontal disease, and anti-TNF-α antibody-based disease modifying therapy significantly lowers salivary IL-1β and TNF-α levels in rheumatoid arthritis.

    In this work, the special portable apparatus was constructed for performing the transillumination examination on interphalangeal joints of patients suffering from rheumatoid arthritis. It consisted of He-Ne laser with optics for collimated illumination, special holder for placing the finger (perpendicular to optical axis, dorsal site towards camera), and CCD camera with memory stick. The captured images in JPEG format with 1152x864 resolution were converted into the gray level pictures and analyzed by means of image processing program from OPTIMAS. 35 ill patients and 11 healthy volunteers were examined. The histograms and 35 luminances were calculated. The average function was applied in order to calculate the mean gray level values in images of corresponding fingers of healthy subjects. These values were compared with values calculated for ill persons. We proved that that transillumination images may have a diagnostic value. For RA suffering patients the corresponding transillumination images represented the lower gray level values than the average value of finger of health volunteers. For II finger of left hand 96% images of ill persons have lower gray level and in case of right hand it was 93%. This proves that basing in transillumination one can diagnose with high probability the patient with rheumatoid arthritis.

    Bilateral chronic anterior uveitis is an extra-articular feature of juvenile idiopathic arthritis. Although figures vary, uveitis occurs in approximately 11%-13% of patients with this disease and is most commonly associated with the female gender, oligoarthritis, and presence of antinuclear antibodies. The disease has an insidious onset and is often asymptomatic. Managing patients with juvenile idiopathic arthritis-associated uveitis remains challenging as the disease may prove to be refractory to traditional treatment regimens. Stepwise immunomodulatory therapy is indicated, with new biologic drugs being used last in cases of refractory uveitis. Small scale studies and practice have provided the evidence to undertake randomized control trials to evaluate the efficacy, safety, and cost-effectiveness of anti-tumor necrosis factor-α therapies, such as infliximab and adalimumab. These have demonstrated promising results, with further data awaited from ongoing trials for adalimumab (as SYCAMORE and ADJUVITE trials). Lower grade evidence is supporting the use of newer biologics such as rituximab, daclizumab, tocilizumab, and abatacept in those cases refractory to anti-tumor necrosis factor-α therapy.

    In recent years there has been a surge of interest in the treatment of chronic inflammatory disorders as a result of the development and application of targeted biological therapies. The elucidation of the overlapping cellular and cytokine immunopathology of such diverse conditions as rheumatoid arthritis (RA), Crohn's disease, and psoriasis points to specific targets for bioengineered proteins or small molecules. Similar to clinical trials in RA, trials in psoriatic arthritis (PsA) have shown excellent clinical results with the tumour necrosis factor (TNF) blockers, etanercept, infliximab, and adalimumab in a variety of domains including the joints, quality of life, function, and slowing of disease progress as evidenced radiologically. In addition, these agents have shown benefit in domains more unique to PsA, such as the skin lesions of psoriasis, enthesitis, and dactylitis, pointing out the similar pathogenesis of the disease in the skin, the tendons, and the synovial membrane. This therapy has been generally safe and well tolerated in clinical trials of PsA. Other logical candidates for targeted therapy in development include other anti-TNF agents, costimulatory blockade agents that affect T cell function, blockers of other cytokines such as interleukin (IL)-1, 6, 12, 15, or 18, and B cell modulatory medicines. Also, it will be useful to learn more about the effects of combining traditional disease modifying drugs and the newer biologicals.

    Pulmonary involvement in rheumatoid arthritis (RA) is common and can be due to the disease itself as well as to the therapies used to treat it. The purpose of this study was to disclose the pulmonary involvement in early RA patients not more than 2 years disease duration using the computed tomography (CT) as well as the pulmonary function tests as ways of pulmonary involvement assessment. Forty patients aged 37.6 ± 10.3 with early rheumatoid arthritis not more than 2 years of disease duration were recruited for the study. All patients were assessed clinically for their RA with DAS28, which was utilized for disease activity determination. Ten percent of our patients were found to be clinically involved by interstitial lung disease (ILD), where 27% have abnormal HRCT finding and 32.5% with abnormal PFT. Predilection for clinically manifest ILD was evident in active RA patients with high DAS28 score, seropositive RA patients, and in patients receiving steroids and anti-TNFα therapy. ILD occurs early in the course of RA, with more predilection for clinically active RA disease.

    Abstract Mycobacterium abscessus is a rapidly growing mycobacterium found mainly in patients with respiratory or cutaneous infections, but it rarely causes disseminated infections. Little is known about the clinical characteristics, treatment, and prognosis of disseminated M abscessus infection. A 75-year-old Japanese woman who had been treated for 17 years with a corticosteroid for antisynthetase syndrome with antithreonyl-tRNA synthetase antibody developed swelling of her right elbow. X-ray of her right elbow joint showed osteolysis, and magnetic resonance imaging revealed fluid in her right elbow joint. M abscessus grew in joint fluid and blood cultures. She was diagnosed with a disseminated M abscessus infection following septic arthritis. Antimicrobial treatment by clarithromycin, amikacin, and imipenem/cilastatin combined with surgical debridement was administered. Although blood and joint fluid cultures became negative 1 week later, the patient died at 6 weeks from starting antimicrobial treatment. We reviewed 34 cases of disseminated M abscessus infections from the literature. Most of the patients had immunosuppressive backgrounds such as transplantation, use of immunosuppressive agents, hematological malignancy, and end stage renal disease. The duration from onset of symptoms to diagnosis was over 3 months in half of the cases. All fatal cases had positive blood cultures or use of immunosuppressive agents. Clinicians should bear in mind that mycobacterial infections including M abscessus are one of the differential diagnoses in patients with subacute arthritis and soft tissue infections. PMID:26020393

    Abstract Nocardia are Gram-positive filamentous bacteria responsible for infections ranging from opportunistic life-threatening disseminated diseases to chronic skin and soft-tissue infections. Even if virtually all organs can be infected, articular involvement is rare. Therefore, we report 3 recent cases and performed a literature review of cases of Nocardia arthritis in order to describe clinical features, therapeutic challenges, and outcome of these patients. Among 34 patients (31 in the literature plus our 3 cases), 21 (62%) were due to hematogenous dissemination, 9 (26%) were due to direct bacterial inoculation through the skin, and in 4 cases, the mechanism of infection was unknown. Four out of these 34 cases occurred on prosthetic joints. Whereas hematogenous infections mostly occurred in immunocompromised hosts (17 of 21, 81%), direct inoculation was mostly seen in immunocompetent patients. Eighty-two percent of patients (28 out of 34) received trimethoprim-sulfamethoxazole-containing regimens and median antibiotic treatment duration was 24 weeks (range, 12–120) for hematogenous infections and 12 weeks (range, 6–24) for direct inoculations. Outcome was favorable in 27 cases despite unsystematic surgical management (17 cases) without sequelae in 70% of the cases. Nocardia arthritis is rare but its management is complex and should rely on a combined approach with rheumatologist, infectious diseases expert, and surgeon. PMID:26496274

    Rheumatoid Arthritis (RA) should be suspected if patients do not only complain of joint pain, but suffer from joint swelling, sensation of heat, hyperemia and warmth around the joints. An arthritic joint pain should be most prominent at night time or early in the morning and cause morning stiffness (> 30 min) of the joint, exercise will improve the symptoms. Diagnosis of RA will be even more likely if wrists, MCP- or PIP joints are affected. Serologic procedures will test for rheumatoid factor or anti-citrullinated antibodies (CCP Ab). One needs to keep in mind that positive results for rheumatoid factor or CCP Ab alone never proves the diagnosis of RA. After diagnosis therapy should be started immediately, recruiting physiotherapy, pain medication, corticosteroids and disease-modifying anti-rheumatic drugs (DMARDs), primarily methotrexate. At the latest after failure of two DMARDs biologics like TNF-α-blockers, an Interleukin-6-Receptor-antibody, a B-cell-specific antibody or a rather T-cell-specific biologic will be initiated. Aim of therapy is freedom of symptoms of an ongoing arthritis, low dosage of immunosuppressants (especially corticosteroids maximally 5 mg/day), stop of radiological progression and prevention of long term consequences of inflammation like myocardial infarction, stroke or lymphoma.

    Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in childhood. The pathogenesis of JIA is thought to be the result of a combination of host genetic and environmental triggers. However, the precise factors that determine one's susceptibility to JIA remain to be unravelled. The microbiome has received increasing attention as a potential contributing factor to the development of a wide array of immune-mediated diseases, including inflammatory bowel disease, type 1 diabetes and rheumatoid arthritis. Also in JIA, there is accumulating evidence that the composition of the microbiome is different from healthy individuals. A growing body of evidence indeed suggests that, among others, the microbiome may influence the development of the immune system, the integrity of the intestinal mucosal barrier, and the differentiation of T cell subsets. In turn, this might lead to dysregulation of the immune system, thereby possibly playing a role in the development of JIA. The potential to manipulate the microbiome, for example by faecal microbial transplantation, might then offer perspectives for future therapeutic interventions. Before we can think of such interventions, we need to first obtain a deeper understanding of the cause and effect relationship between JIA and the microbiome. In this review, we discuss the existing evidence for the involvement of the microbiome in JIA pathogenesis and explore the potential mechanisms through which the microbiome may influence the development of autoimmunity in general and JIA specifically.

    The inflammatory response by secretion of cytokines and other mediators is postulated as one of the most significant factors in the pathophysiology of juvenile idiopathic arthritis (JIA). The effect of macrophage action depends on the type of their activation. Classically activated macrophages (M1) are responsible for release of molecules crucial for joint inflammation. Alternatively activated macrophages (M2) may recognize self antigens by scavenger receptors and induce the immunological reaction leading to autoimmune diseases such as JIA. Molecules essential for JIA pathophysiology include: TNF-α, the production of which precedes synovial inflammation in rheumatoid arthritis; IL-1 as a key mediator of synovial damage; chemotactic factors for macrophages IL-8 and MCP-1; IL6, the level of which correlates with the radiological joint damage; MIF, promoting the secretion of TNF-α and IL-6; CCL20 and HIF, significant for the hypoxic synovial environment in JIA; GM-CSF, stimulating the production of macrophages; and IL-18, crucial for NK cell functions. Recognition of the role of macrophages creates the potential for a new therapeutic approach.

    Registries estimate that one third of patients with psoriatic arthritis (PsA) are "resistant" to of TNF-alpha blockers. Therefore, the search for new approaches to treatment of this disease may be justified. Currently the treatment options that have proven effective are associated with inhibition of the T cell costimulatory pathway (abatacept and alefacept) and blocking the P40 fraction of IL-12 and IL-23 (ustekinumab). A novel pathway inhibition, which deserves special attention is offered by apremilast. This molecule inhibits phosphodiesterase IV, responsible for hydrolyzing cyclic adenosine monophosphate to adenosine monophosphate, which causes an increase in cAMP. This metabolite is associated with decreased TNF-alpha. It has a modest efficacy (ACR 20 response of 43%), and subsequent studies have shown an improvement in visual analog scale and the SF36 compared to placebo. Currently there are five clinical trials in phase III to assess its effectiveness in parameters of inflammation and radiographic progression. The spectrum of possibilities before treatment failure with anti-TNF alpha, is augmented by the appearance of several reports that show efficacy with the individual use of CD20 inhibitors and IL-1. In patients with rheumatoid arthritis (RA) the effectiveness of molecules that inhibit signal transduction of cytokines (Anti-JAK) has been proven, so it is possible that in the future they may be used in patients with PsA.

    Changes in natural killer (NK) cell activity were studied in patients with polyarthritis associated with rubella or Ross River virus infections. In 30 of 32 Ross River virus patients, peripheral NK cell activity was depressed at some stage of the disease but returned to normal levels as patients recovered from arthritic symptoms. Similar changes did not occur in rubella patients and no difference was found between changes in peripheral NK activity and serum interferon (IFN) levels in rubella patients with arthritis and those without. Neither the peak of NK cell activity in peripheral blood lymphocytes (PBL) recovered early in Ross River virus and rubella infections, nor the depression of NK cell activity late in Ross River virus infections could be correlated with changes in serum IFN levels. The decrease in PBL-NK cell activity in epidemic polyarthritis (EPA) patients could not be attributed solely to loss of NK cells from the peripheral circulation because limiting-cell-dilution (LCD) analyses indicated changes in peripheral NK cell activity were due to changes in both the number and lytic activity of NK cells. Despite the association between HLA-DR7 and EPA no differences were found in levels of peripheral NK cell activity in DR7+ and DR7- EPA patients. The demonstration that peripheral NK cells could kill autologous synovial cells suggested that NK cells in joints of EPA patients may contribute to the arthritis associated with Ross River virus infection.

    Septic arthritis and toxic synovitis are clinical conditions that can develop in association with various causes and involve symptoms such as pain, swelling, redness, sensitivity and restricted movement in the joint. A 42-year-old male presented to the emergency department with severe joint pain and nausea after injecting a 1-cc mixture of turpentine oil, eucalyptus oil, mint oil and thyme oil, which he purchased from an alternative medicine store, into his right knee with a syringe because of chronic knee pain. Ballottement and sensitivity were present at physical examination. Knee puncture yielded 60 cc of cloudy fluid. There was no growth in the material obtained. Improvement was observed following subsequent arthroscopic washing of the joint space and IV antibiotherapy, and the patient was discharged on day 21 of hospitalization with oral antibiotic and analgesic therapy. Intra-articular injection of foreign bodies into the knee joint space for therapeutic purposes, as in this case report, is a very rare occurrence, but may lead to potentially complicated arthritis.

    Background and purpose Most studies on total ankle replacement (TAR) have used a case mix of patients. We evaluated the outcome of TAR performed for end-stage arthritis either because of fracture or ligamentous injury. Patients and methods We prospectively followed 88 consecutive patients (50 postfracture ankles and 40 ankles with instability arthritis (2 bilateral)) who underwent TAR between 2001 and 2009. Mean follow-up for both groups was 5 years. Results Preoperative varus deformity of 10° or more was present in 23 ankles in the instability group. At 6 years, survival with revision or salvage fusion as an endpoint was 87% (95% CI: 74–99) in the postfracture group and 79% (95% CI: 63–94) in the instability group. Progressive periprosthetic osteolysis was seen in 23 ankles, and required salvage fusion in 6. The number of reoperations was similar in both groups. Clinical outcome, as assessed with 2 ankle scores and 2 questionnaires, showed good results and was similar at the latest follow-up. Interpretation The outcome was similar in the postfracture and instability groups and also similar to that reported in series including a case mix of patients. In contrast to earlier reports, preoperative frontal plane deformity in this series was not identified as a risk factor for failure. PMID:25772269

    There is need for a greater readiness among the medical and paramedical professions to recognize the widespread occurrence of sexual problems in patients with arthritis and allied conditions. Sexual image, sexual drive, sexual competence, sexual expression, and sexual opportunity may all be adversely affected by the onset of arthritis, the type and degree of effect depending on the nature, severity, and duration of the disease and on the social and marital state of the patient. Single patients may have difficulty in forming stable sexual relationships and married patients in creating a mutually satisfying pattern of sexual expression. The physical and psychological state of patient and partner and the medication of both need careful consideration to determine contributory causes to the individual problem-complex of each patient. Based on the experience of 12 years' sexual counselling at a disabled living unit and an orthopaedic hospital, and of 4 years at a weekly clinic for disable people with sexual problems, the causes and means of amelioration of these problems are discussed.

    Objective To test new platelet indices for patients with rheumatoid arthritis (RA) as new acute phase reactants. Material and Methods In total, 120 patients with RA and 40 patients in the control group were analyzed. A DAS 28 score over 2.6 was accepted as active disease, and a DAS 28 score lower than 2.6 was accepted as under remission. Platelet distribution width, plateletcrit, and mean platelet volume were analyzed for three groups: patients with active RA, patients under remission, and the control group. Results There were 72 patients with active disease and 48 patients under remission. The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), mean platelet volume (MPV), plateletcrit (PTC), and platelet distribution width (PDW) scores were all statistically different among groups. In our data, PTC was found to be a positive acute phase reactant and others were negative acute phase reactants for patients with RA. Conclusion These new indices are cheap, widely available, and useful parameters for routine clinical rheumatology practice.

The patient's Typhidot test was positive for IgM antibodies. Her Widal test was negative, and blood culture and synovial fluid culture were sterile. She was started on ceftriaxone, to which her fever initially responded. However, after 4 days of treatment her disease course was complicated by relapse of fever and acute respiratory distress syndrome (ARDS). This settled with respiratory support and addition of azithromycin. Following recovery from ARDS and fever, her persistent knee arthritis responded to intra-articular methyl prednisolone instillation. PMID:25336548

    Systemic juvenile idiopathic arthritis (sJIA) is a severe inflammatory childhood disorder, characterized by a specific pattern of systemic features and a typical cytokine profile. Patients are at risk to develop macrophage activation syndrome (MAS), an acute life-threatening condition defined by excessive proliferation and activation of macrophages and T cells. Defects of unknown cause in the natural killer (NK) cell cytotoxic capacity are presumed to underlie the pathogenesis of MAS and have been detected in sJIA patients. Here, we provide an overview of the cytokine profiles in sJIA and related mouse models. We discuss the influence of cytokines on NK cell function, and hypothesize that NK cell dysfunction in sJIA is caused by altered cytokine profiles.

    We report the acute onset of polyarticular inflammatory arthritis in 2 patients receiving the immune check-point inhibitor, pembrolizumab (MK-3475), anti-PD1 drug for metastatic melanoma after 14 and 11 months therapy, respectively. The first patient had severe tenosynovitis, synovitis, bone marrow edema, and myositis, whereas the second patient had predominantly synovitis and tenosynovitis. Good symptomatic control was obtained with bisphosphonates and salazopyrin, avoiding the use of T-cell immunosuppressants. These cases raise important questions on whether anti-PD1 therapy allows preexisting autoimmune T-cell clones to escape tolerance by suppressing regulatory T cells or whether they allow autoimmunity to develop de novo. These conditions heighten our awareness of complications associated with the clinical use of these agents, and provide a prototypical model for future research into the understanding of autoimmunity.

    Rheumatoid arthritis is a systemic disease in which cerebral and eye involvement is neither common nor fully understood. Although it is rarely the cause of pachymeningitis and optic neuritis, rheumatoid arthritis should always be kept in mind in these two conditions. We present a 52-year-old male with an 8 month history of rheumatoid arthritis who was referred to the neurology department with headache and decreasing vision and was diagnosed as having rheumatoid pachymeningitis and optic neuritis on the basis of MRI findings.
