OBJECTIVES The pathogenesis of Behçets disease (BD) is closely related to endothelial cells, leucocyte functions and autoimmunity. The aim of this study was to investigate circulating selectin adhesion molecules, which are known to play a significant part in the immune response especially by regulating interactions of the leucocytes with endothelium, in BD. METHODS Plasma E-, L-, and P-selectin concentrations were evaluated in 11 patients with widespread BD (group I), 10 cases with merely mucocutaneous involvement (group II) and 15 age and sex matched healthy control subjects. The patients were newly or previously diagnosed cases not taking any drug for BD. RESULTS Plasma concentrations of all selectins were significantly higher in group I compared with group II. E-selectin and P-selectin were significantly increased in each subgroup of patients compared with the healthy controls. L-selectin concentrations were higher than the controls only in group I. CONCLUSIONS Increases in the selectins in BD may be a direct consequence of the leucocyte, endothelium and platelet activations observed during the disease process. However, abnormal/increased selectin expression to various triggers should also be considered. More prominent increases in patients with extensive disease suggest that circulating selectin concentrations are related to disease severity.

Elevated neutrophil count is associated with poor prognosis and increased mortality in many conditions. Neutrophil to lymphocyte ratio (NLR) has emerged as a marker of inflammation in neoplastic and cardiovascular disorders. Herein, we investigated utility of this simple tool in rheumatoid arthritis (RA) and ankylosing spondylitis (AS).

ObjectiveReal-time sonoelastography (SE) is a new ultrasound-based imaging technique that provides information on tissue elasticity and stiffness. We determined the efficacy of SE for assessing Achilles tendon abnormalities in patients with ankylosing spondylitis (AS).Materials and methodsForty-one consecutive AS patients and 32 asymptomatic healthy subjects were enrolled. Achillodynia was scored on a 0- to 100-mm visual analog scale. A high-resolution ultrasound machine equipped with an elastography-compatible linear probe was used to perform bilateral B-mode ultrasound, Doppler ultrasound, and SE examinations of Achilles tendons. Tendons were divided into proximal, middle, and distal segments. B-mode examinations included tendon thicknesses, echotextures, and enthesopathic findings. SE using color-coded images was performed in the same areas. Normal consistent tendon structures were coded as blue or green, and moderately (yellow) or severely (red) softened areas were considered pathological.ResultsThe distal third of the Achilles tendons was the most commonly affected part in the AS patients compared with healthy subjects (p = 0.001), whose middle third was more commonly affected. Achillodynia intensity tended to be higher in patients with pathological B-mode or SE examination findings (p = 0.09 and p = 0.07 respectively). Softening detected by SE in the distal third was associated with enthesopathy findings such as calcaneal bone erosions (Fisher’s X2, p = 0.07) and tendinous enlargement (Fisher’s X2, p = 0.001). B-mode and SE findings had moderate to good correlation in the assessment of Achilles tendon abnormalities.ConclusionsSonoelastography may be useful for the evaluation of tendon abnormalities in patients with AS; in addition; it may be useful for the evaluation of other inflammatory rheumatic conditions.

Protracted febrile myalgia syndrome (PFMS) is a very rare but severe manifestation of familial Mediterranean fever (FMF) which is characterized by severe debilitating pain in large muscle groups that may last for several weeks. Colchicine is ineffective and treatment is largely supportive. Demonstration of crucial role of interleukin-1 (IL-1) in the pathogenesis of FMF has increased the use of IL-1 blockers in colchicine resistant or intolerant patients. Herein, we reported successful use of an IL-1 inhibitor, anakinra, in treatment of two patients with PFMS.

[Purpose] Although oxidative stress is known to be present in rheumatoid arthritis (RA), the effects of exercise on oxidative parameters are unknown. The aim of this study was to investigate the effects of acute aerobic exercise on serum oxidant and antioxidant levels in patients with RA. [Subjects and Methods] Sixteen patients with RA and 10 age-matched healthy volunteers participated in this study. All participants wore polar telemeters and walked on a treadmill for 30 minutes at a speed eliciting 60–75% of maximal heart rates. Blood samples were obtained before, immediately and 24 hours after exercise and malondialdehyde (MDA) and total sulfhydrile group (RSH) levels were measured. [Results] Both groups had similar heart rates during the test but the treadmill speed of the RA patients was significantly lower than that of the healthy volunteers. Serum MDA levels were lower than in both groups immediately after exercise, with greater decrements in the RA patients than controls. MDA levels returned to baseline 24 hours after the exercise only in the controls; they remained low in the RA patients. There was a slight increase in serum RSH levels after exercise compared to baseline in both groups. [Conclusion] Moderate intensity treadmill exercise did not have any adverse effect on the oxidant-antioxidant balance. The results suggest that such an exercise may be safely added to the rehabilitation program of RA for additional antioxidant effects. Morever, this antioxidant environment is maintained longer in RA patients.

Objective: To report a patient with coeliac disease (CD) associated with primary biliary cirrhosis (PBC) who presented with myopathy without classical symptoms of CD. Clinical Presentation and Intervention: A 42-year-old woman presented with inability to walk and marked loss of motor function. She had elevated liver enzymes with a cholestatic pattern. Antimitochondrial antibody M2 band, anti-endomysial antibody, antigliadin IgA and IgM were positive. Histopathologic findings of the liver revealed PBC and duodenal biopsy was consistent with CD. She was also found to have osteomalacia. She showed slow response to gluten-free diet, but accelerated full recovery with vitamin D replacement. Conclusion: In PBC patients with subclinical CD and myopathy, vitamin D status can provide a basis for treatment.

Background. Systemic amyloidosis is a potentially fatal condition, unless diagnosed and treated before development of irreversible organ damage. Demonstration of amyloid deposits within tissue biopsies is only definitive diagnostic method, which makes appropriate selection of biopsy site essential. Herein, we evaluated efficacy of minimally invasive minor salivary gland biopsy (MSGB) for the diagnosis of amyloidosis. Methods. We analyzed 37 biopsies taken from 35 patients. Suggestive findings for amyloidosis were significant proteinuria, renal impairment, refractory diarrhea, neuropathy, and restrictive cardiomyopathy. Minor salivary gland was the initial biopsy site in all subjects. When MSGB was negative but there was a high suspicion for amyloidosis, a kidney, duodenum, or rectal biopsy was performed for further investigation. Results. Mean age of patients was 45.4 and 21 were female. In 11 patients amyloidosis was diagnosed with MSGB. In overall 18 patients were diagnosed with amyloidosis. Sixteen of them were identified as being of AA type and two were AL type amyloidosis. The sensitivity of minimally invasive MSGB is 61.1% for diagnosing amyloidosis in this study. Conclusion. MSGB is a safe and simple method for the diagnosis of amyloidosis which can be performed in an outpatient setting. We suggest extensive use of this minimally invasive method.

Familial Mediterranean fever (FMF) is characterized by recurrent inflammation of serosal and synovial membranes. Despite the fact that it is a genetic disease, environmental factors, including infections, are shown to be triggering factors associated with the precipitation of attacks in FMF. Antimicrobial peptides (AMPs) are components of innate immunity which exert antimicrobial activity against many microorganisms. Human AMPs; cathelicidin (LL37) and defensins have immunomodulatory properties and are involved in the pathogenesis of many inflammatory disorders. Hence, we investigated serum AMPs in 23 newly diagnosed FMF patients. Blood samples were obtained at baseline, 6 months after initiation of colchicine and during an attack. Twenty-four healthy individuals constituted the control group. The concentrations of LL37, alpha-1, beta-1 and beta-2 defensins were determined by ELISA. Serum AMPs did not change during attacks and did not correlate with acute phase reactants. However, serum LL37 and defensins were found to be remarkably higher in FMF patients compared to healthy individuals both at baseline and 6 months after initiation of colchicine therapy which suggest that AMPs might have a role in the pathogenesis of FMF.

Abstract Background: Colchicine is the mainstay of the treatment of familial Mediterranean fever (FMF). However, 10% of FMF patients do not respond well to colchicine. Efficacy of interleukin (IL)-1 inhibitors in reducing attacks have been demonstrated in colchicine-resistant FMF (crFMF) patients recently. Colchicine is still the only approved drug for the prevention of amyloidosis in FMF and utility of IL-1 inhibitors in crFMF cases who already has amyloidosis remain to be elucidated. Herein, we evaluated efficacy and safety of IL-1 inhibitors in patients with crFMF-associated AA amyloidosis in a relatively large single center study. Methods: Medical records of FMF patients complicated with AA amyloidosis in our dedicated FMF center were retrospectively reviewed and those patients who ever treated with IL-1 inhibitors were enrolled into the study. Patient global, physician global assessments (on 0–10 cm visual analog scale), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), serum creatinine and 24-h urinary protein excretion values for each visit were recruited from computer-based hospital records. Treatment response of patients were assessed with clinical symptoms, serum albumin, CRP and ESR values. Renal outcome parameters were analyzed on those not receiving renal replacement therapy. Results: Seventeen patients were identified with crFMF-amyloidosis that ever treated with IL-1 inhibitors. Background colchicine therapy was continued in all patients in maximal-tolerated dose along with IL-1 inhibitors. All patients benefit from IL-1 antagonists assessed by patient and physician global assessments. Inflammatory markers, CRP and ESR, were significantly reduced in all and normalized in 12 out of 17 patients. More importantly, the amount of proteinuria was remarkably improved following IL-1 inhibitor therapy (1606 mg/day to 519 mg/day, p = .008). Both anakinra and canakinumab were well-tolerated without severe side effects. All patients were initially treated with anakinra but switched to canakinumab in seven patients (one leukopenia, four injection site reaction, two inefficacy). Conclusion: We evaluated the clinical and laboratory responses to IL-1 inhibitors in crFMF-associated amyloidosis patients. We found significant decreases in CRP, ESR and proteinuria after IL-1 inhibitor therapy. This study confirmed that IL-1 inhibitors are effective for controlling attacks and inflammatory activity in FMF patients complicated with AA amyloidosis. Moreover, they reduce or stabilize amount of proteinuria and preserve renal function in short-term follow-up. Prolonged prospective clinical trials are warranted to assess their long-term efficacy in this particular patient group.
