ABSTRACT
Objective:To describe the clinical features and immunological of Uygur systemic lupus erythematosus (SLE) subjects.Methods:Atotal of 484 adult patients (≥18 years) followed in the People's Hospital of the Xinjiang Uygur Autonomous Region were included into this study including 211 Uygur patients with SLE and 273 Han patients with SLE.Results:① Of the 211 Uygur SLE patients, 195 (92.4%) were female and 16(7.6%) were male (female:male=12.2∶1), the mean age at SLE onset was 15-64(35±12) years, mean disease duration was 0.1-228(21±35) months.② Of the 211 Uygur SLE patients, the most prevalent clinical presentationswere renal involvement 56.4%(119/211), hematological 56.4%(119/211), rash 50.2% (106/211), arthralgia/arthritis 49.8%(105/211), weakness 47.9%(101/211). The significant difference observed between the Uygur and Han SLE patients was Raynaud phenomenon( χ2=6.066, P=0.014) .③ The positive rates of antinuclear antibodies were 94.8%(200/211), 54.5%(115/211) for anti-dsDNA antibodies, 47.9% (101/211) for anti-SSA antibodies, 35.1%(74/211) for anti-U 1-RNP antibodies, and 28.4%(60/211) for anti-AHA antibodies. The positivity of anti-AHA antibodies ( χ2=4.952, P=0.026) was higher in Uygur SLE patients than thatin Han SLE patients. More Uygur SLE patients were anemic ( χ2=6.904, P=0.009), with decrease of complement ( χ2=6.330, P=0.012). Conclusion:This study can not find any significant differences between the Uygur SLE patients and Han SLE patients in common clinical manifestations in Xinjiang. The Uygur SLE patients are more likely to have anemia and decrease of complement, which may be related to race and diet habits.
ABSTRACT
Objective@#To explore the clinical value of serum autoantibodies and human leukocyte antigen (HLA-B27) molecular testing in Uygur patients with human immunodeficiency virus (HIV) infection.@*Method@#A total of 727 HIV-infected Uygur patients who visited Kuche infectious diseases hospital during May 2016 to March 2017 were include in this study. The other 390 healthy people were enrolled as controls. Serum antinuclear antibodies (ANA), anti-cyclic citrullinated peptide (CCP) antibody, anti-extractable nuclear antigen (ENAs) antibody and HLA-B27 molecule were tested.@*Result@#Among 727 HIV-infected Uygur patients, 317 were males and 410 were females with mean age (35.52±13.44) years old. The mean duration of disease was (6.34±3.05) years. There were 697 (95.87%) patients receiving highly active antiretroviral therapy (HAART) with mean duration of treatment (5.52±3.47) years. The mean CD4+T cell count was (520±271) cells/μl in 202 HIV-infected patients, and mean virus load was (108 139±20 498) copies/ml in 20 HIV-infected patients. Rheumatic manifestations were recorded in 238 (32.74%) HIV-infected Uygur patients, mainly with dry mouth and dry eye (15.41%) , alopecia (9.90%) , arthralgia (8.94%) , ect. Compared with the health controls, positive ANA was more common in HIV infected Uygur patients (33.43% vs. 17.43%, P<0.001) with low titers (ANA titer:1∶100) . HIV-infected Uygur patients had higher positive anti-u1-RNP antibodies positive rate (1.10%), but lower anti-SSA antibodies positive rate (0.14%) and anti-CCP antibodies positive rate (0.28%). Patients with positive ANA in HAART group were significantly less than that in non-treatment group (32.71% vs. 50.00%, P=0.049). There were no correlations between ANA and duration of HAART, CD4+T cell counts and virus load (r values 0.061, 0.047, 0.121, respectively. P>0.05). Only one female patient was HLA-B27 positive (0.14%), which was significantly lower than that in healthy controls (3.08%) (P<0.001). Also, only one patient was diagnosed with rheumatoid arthritis (RA).@*Conclusion@#Autoimmune manifestations are common in HIV-infected Uygur patients. Several autoantibodies are positive, but the coincidence of rheumatic diseases is rare. It′s noted that patients with autoimmune manifestations should be considered as a differential diagnosis of HIV infection.

ABSTRACT
Objeictivie To investigate the diagnostic value of anti-mutated citrullinated vimentin (anti-MCV) antibody, anti-cyclic citrullinated peptide (anti-CCP) antibodies and glucose-6-phospha-teisomerase (GP1) for rheumatoid arthritis (RA). Methods Anti-MCV antibody, GPI and anti-CCP antibody were detected in serum samples of 109 RA patients, 24 non-RA rheumatic diseases patients and 19 healthy blood donors. The sensitivity and specificity of these parameters for the diagnosis of RA were analyzed. Results Both the positive rate and average cut off concentration of anti-MCV and GPI in RA were higher than those of non-RA rheumatic diseases or healthy controls (P<0.05). A significant difference was found between anti-MCV and GPI in RA patients. The most sensitive and specific parameter in RA was anti-MCV (99.1%) and anti-CCP (90.7%) respectively, but, when anti-MCV combined with anti-CCP, or GPI or anti-CCP and GPI, the specificity could be up to 98.1%. Coniclusions Anti-MCV, anti-CCP and GPI alone or in combination may be valuable parameters for the diagnosis of RA.
