Introduction. Chikungunya virus infection (CKV) may lead to chronic arthritis in up to 40% of the patients. There are previous data regarding positive auto antibodies in CKV. Objective is to systematically evaluate the prevalence of auto antibodies in CKV patients. Methods. All study participants had clinical manifestations being CKV positive at least serologally or by RT-PCR data. The following autoantibodies were assessed: antinuclear antibodies (ANA), anti-dsDNA, anti-Sm, anti-Ro/SS-A, anti-La/SS-B, anti-U1RNP, IgG and IgM anticardiolipin, anticyclic citrullinated peptide (antiCCP), rheumatoid factor (RF), antiribosomal P protein, lupus anticoagulant, anti-Jo-1 and anti-Scl-70. CH100, C3 and C4 complement components, serum levels of immunoglobulins, C-reactive protein, erythrocyte sedimentation rate, alpha1-acid glycoprotein, antithyroglobulin, antithyroperoxidase, TRAb, 25 hydroxyvitamin D (25OHD), dengue and zika IgG and IgM antibodies were also measured. Results. 30 CKV patients were included. Mean age was 59.1±15.7 years, 85% females and 77% Caucasian subjects. Disease duration comprised 4.9±4.0 months. Oligoarthritis was observed in 93% cases. Mean C-reactive protein levels were 10.1±6.8 ng/dL, erythrocyte sedimentation rate — 34.2±19.9 mm/1st hour and alpha1-acid glycoprotein 115.5±52.6 mg/dL. Intramuscular betamethasone depot single dose injection was administered in 54%, prednisone — in 15% and methotrexate — in 23% cases. Importantly, 1/30 (3.3%) cases was positive for ANA, 4/30 (13.3%) — for RF and none was positive for anti-CCP or any other autoantibodies. Complement and immunoglobulin levels were all within the normal range. Low levels of 25OHD were observed in 88% cases.

Introduction. Ankylosing spondylitis (AS) is a chronic inflammatory disease that affects sacroiliac joints, spinal column and peripheral joints. Beside medication therapy, physical and balneotherapy play an important role in its complex treatment. Objective. The aim of the research was to establish serum concentrations of C-reactive protein (CRP), ? 1-acid glycoprotein (? 1-AGP), ceruloplasmine (CP) and erythrocyte sedimentation rate (SE) before and after the balneotherapy in ankylosing spondylitis. Methods. The research included 50 AS patients according to the revised New York criteria, of mean age 43 years, who were treated for 14 days on the average at the Clinic for Rheumatology of the Institute 'Niska Banja'. All the patients received medications and balneotherapy (radioactive oligomineral baths, peloid, massage, kinesitherapy); the serum concentrations of CRP, ?1-AGP, CP and SE were measured before and after balneotherapy. Serum proteins were determined using original Nor Partigen plates Boehringer. Erythrocyte sedimentation rate was measured by Westergreen method. Balneotherapy was applied individually, intensively or mildly, depending on the AS stage and activity phase. Results. After dosed balneotherapy, a significant decrease in the concentrations of CP (p<0.05), ?1-AGP (p<0.01) and CRP (p<0.05) was registered in the serums of AS patients. ESR was not significantly reduced. Conclusion. The research proved that ? 1-acid glycoprotein, ceruloplasmine and C-reactive protein represent more sensitive inflammation markers as compared to erythrocyte sedimentation rate. The identification of acute phase reactants is important in the evaluation of dosed balneotherapy efficiency in the treatment of ankylosing spondylitis.

BACKGROUND: The diagnosis of osteomyelitis is a key step of diabetic foot management. Procalcitonin (PCT) is a novel infection marker. This study aimed to investigate the diagnostic value of procalcitonin and other conventional infection markers and clinical findings in diagnosis of osteomyelitis in diabetic foot patients. METHODS AND MATERIALS: This diagnostic value study was carried out on ninety patients with diabetic infected foot ulcers admitted in Kashan Beheshti Hospital, 2016. After obtaining consent, 10 cc blood sample was taken for measuring serum PCT, CBC, ESR, CRP and FBS. Clinical characteristics of the wounds were noted. Magnetic resonance imaging of the foot was performed in all patients to diagnose osteomyelitis. All statistical analyses were done with the use of SPSS-16. RESULTS: PCT levels were 0.13 ± 0.02 ng/mili patients with osteomyelitis (n= 45) and 0.04 ± 0.02 ng/ml in patients without osteomyelitis (n= 45). PCT, Erythrocyte sedimentation rate and C-reactive protein was found significantly higher in patients with osteomyelitis (p< 0.001). The ROC curve was calculated for PCT. The area under the ROC curve for infection identification was 1 (p< 0.001). The best cut-off value for PCT was 0.085 ng/ml. Sensitivity, specificity, and positive and negative predictive values were 100%, 97.8%,97.8% and 100%, respectively. CONCLUSION: In this group of patients, PCT was useful to discriminate patients with bone infection. Also, Erythrocyte sedimentation rate and C-reactive protein can be used as a marker of osteomyelitis in diabetic patients.
