ABSTRACT

BACKGROUND@#Human neutrophil lipocalin (HNL) has been used extensively to differentiate acute bacterial infection from febrile diseases as a biomarker to reflect the activation of the neutrophil. The serum HNL levels in the adult-onset Still's disease (AOSD) patients with and without infection, as well as the healthy controls (HCs), were analyzed statistically in this study to evaluate the value of HNL for the diagnosis of AOSD.@*METHODS@#A total of 129 AOSD patients were enrolled, from whom blood samples were drawn and the AOSD diagnosis was confirmed through the review of the medical records, where the systemic score, demographic characteristics, clinical manifestations, and laboratory parameters were also collected for the patients; in addition, a total of 40 HCs were recruited among the blood donors from the healthcare center with the relevant information collected. The HNL test was done for the blood samples with the enzyme-linked immunosorbent assay and the analyses were done for the correlations of HNL with clinical manifestations and diagnostic effectiveness.@*RESULTS@#The serum HNL increased significantly in the patients with only AOSD as compared with that in the HCs (139.76 ± 8.99 ng/mL vs . 55.92 ± 6.12 ng/mL; P  < 0.001). The serum HNL level was correlated with the white blood cell (WBC) count ( r  = 0.335, P  < 0.001), neutrophil count ( r  = 0.334, P  < 0.001), erythrocyte sedimentation rate ( r  = 0.241, P  = 0.022), C-reactive protein ( r  = 0.442, P  < 0.0001), and systemic score ( r  = 0.343, P  < 0.0001) in the AOSD patients significantly. Patients with fever, leukocytosis ≥15,000/mm 3 , and myalgia in the HNL-positive group were observed relatively more than those in the HNL-negative group ( P  = 0.009, P  = 0.023, and P  = 0.007, respectively). HNL was a more sensitive indicator than ferritin and C-reactive protein (CRP) to differentiate the AOSD patients with bacterial infection from AOSD-only patients, and the Youden index was 0.6 for HNL and 0.29 for CRP.@*CONCLUSION@#Serum HNL can be used as a biomarker for the diagnosis of the AOSD, and HNL is also observed to be associated with the disease activity.

ABSTRACT

BACKGROUND@#Antiphospholipid syndrome (APS) is an autoimmune prothrombotic condition with significant morbidity. The objective of this study was to identify additional clinical and epidemiological risks of arterial thrombosis, venous thrombosis, and pregnancy morbidities in a large cohort of persistent antiphospholipid antibodies (aPLs)-positive carriers.@*METHODS@#This was a cross-sectional cohort study of 453 consecutive patients with a documented positive aPL who attended Peking University People's Hospital. Among 453 patients screened, 297 patients had persistent positive aPL. We compared asymptomatic aPL carriers with thrombotic and obstetric APS patients. And the univariate analysis and multivariable logistic regression were used to evaluate the association between different risk factors and APS clinical manifestations. The levels of circulating markers of neutrophil extracellular traps (NETs) (cell-free DNA and citrullinated histone H3 [Cit-H3]) were assessed and compared among aPL-positive carriers with or without autoimmune disease and APS patients.@*RESULTS@#Additional risk factors associated with arterial thrombosis among aPL-positive carriers included: smoking (odds ratio [OR] = 6.137, 95% confidence interval [CI] = 2.408-15.637, P  = 0.0001), hypertension (OR = 2.368, 95% CI = 1.249-4.491, P  = 0.008), and the presence of underlying autoimmune disease (OR = 4.401, 95% CI = 2.387-8.113, P < 0.001). Additional risks associated with venous thrombosis among aPL carriers included: smoking (OR = 4.594, 95% CI = 1.681-12.553, P  = 0.029) and the presence of underlying autoimmune disease (OR = 6.330, 95% CI = 3.355-11.940, P < 0.001). The presence of underlying autoimmune disease (OR = 3.301, 95% CI = 1.407-7.744, P  = 0.006) is the additional risk, which demonstrated a significant association with APS pregnancy morbidity. Higher circulating levels of cell-free DNA and Cit-H3 were observed among APS patients and aPL patients with autoimmune diseases compared with those aPL carriers without underlying autoimmune diseases. Furthermore, control neutrophils that are conditioned with APS patients'sera have more pronounced NET release compared with those treated with aPL carriers'sera without underlying autoimmune diseases.@*CONCLUSIONS@#We identified several potential additional risk factors for APS clinical manifestations among a large cohort of Chinese aPL carriers. Our data may help physicians to risk stratify aPL-positive Asian patients.

ABSTRACT

Objective:To analyze the association between thrombocytopenia and clinical manifestations in patients with antiphospholipid syndrome (APS), and the significance of adding thrombocytopenia to the classification criteria of APS.Methods:One hundred and sixty one APS patients admitted to Peking University People's Hospital from January 2003 to August 2017 were retrospectively analyzed. Clinical and laboratory data were compared between patients with and without thrombocytopenia. Chi-square test, Fisher's exact test and t test were used for statistical analysis. Results:Among 161 APS patients, 48 patients (29.8%) were primary APS and 113 patients (70.2%) were secondary APS. Ninety-one patients (56.5%) experienced thrombocytopenia, while 62 patients (38.5%) had thrombocytopenia as the initial symptom. Among primary APS patients, compared with patients without thrombocytopenia, the prevalence of thrombosis was significantly lower in patients with thrombocytopenia (40.0% vs 69.6%, χ2=4.218, P=0.040), especially venous thrombosis (20.0% vs 47.8%, χ2=4.174, P=0.041). Among secondary APS patients, compared with patients without thrombocyt-openia, the prevalence of thrombosis, arterial thrombosis (21.2% vs 42.6%, χ2=5.944, P=0.015) and venous thrombosis (22.7% vs 51.1%, χ2=9.753, P=0.002) was significantly lower in patients with thrombocytopenia (43.9% vs 80.9%, χ2=15.496, P<0.01). As for laboratory findings, primary APS patients with thrombocytopenia showed a higher proportion of positive aCL findings (80.0% vs 52.2%, χ2=4.174, P=0.041), while secondary APS patients with thrombocytopenia experienced more leukopenia (25.8% vs 10.6%, χ2=4.002, P=0.045), lower complement C3 levels (78.7% vs 44.4%, χ2=13.205, P<0.01) and complement C4 levels (74.6% vs 46.7%, χ2=8.485, P=0.004). The proportion of patients fulfilling 1988, 1989, 1999 and 2006 APS classification criteria in our cohort was 88.2%, 87.0%, 64.0% and 70.8%, respectively. Inclusion of thrombocytopenia into 2006 criteria improved the proportion to 96.3%. Conclusion:The prevalence of thrombosis in APS patients with thrombocytopenia is significantly low. Thrombocytopenia is an important clinical manifestation of APS which can improve the diagnostic accuracy of APS.

ABSTRACT

Objective:To investigate the level and the influencing factors of blood uric acid in monks and nuns in Wutai Mountain area, and to explore the relationship between blood uric acid level and BMI and blood lipids levels.Methods:Physical examinations and laboratory tests were performed on monks and nuns in Wutai Mountain area. There were 207 males and 261 females. Physical examination includes height, weight, blood pressure, blood uric acid, blood lipid, blood glucose and other indicators. The blood uric acid level was measured using the uricase method. Chi-square test for trend, and t test were utilized for statistical analysis. Results:The average blood uric acid level of the monk and the nun was (372±6) μmol/L and (290±4) μmol/L, respectively. Obviously, the average blood uric acid level of the monk was significantly higher than it in the nun ( t=11.636, P<0.01). The total incidence rate of hyperuricemia, which was diagnosed when the blood uric acid level was higher than 420 μmol/L in males and the blood uric acid level was higher than 360 μmol/L in females. In particular, the incidence rate of hyperuricemia was much higher in the monk (24.3%, 50/207) than in the nuns (13.4%, 35/261) ( χ2=8.966, P<0.01) . Analysis by age, the prevalence of hyperuricemia in men was 20.3%(42/207) before the age of 50, which was higher than that after the age of 50 (3.9%, 8/207) ( χ2=26.3, P< 0.01); The prevalence of hyperuricemia in women before the age of 50 was 2.7%(7/261), which was lower than that after the age of 50 (10.7%, 28/261) ( χ2=13.51, P<0.01). The uric acid level of men and women between 50-60 years old, showed the opposite trend. The level of uric acid in men decreased and increased in women. In addition, the prevalence of triglyceride abnormalities and overweight was more significantly in monks and nuns with high uric acid than those with the normal uric acid level [71.8%(61/85) vs 45.2%(173/383), χ2=19.68, P<0.01; 54.1%(46/85) vs 19.8%(76/383), χ2=42.4, P<0.01]; while no significant difference of total cholesterol and blood glucose levels was observed between these two groups. Conclusion:There are differences in blood uric acid levels among Wutai Mountain area monks and nuns of different ages and genders. The level of blood uric acid in male is significantly higher than that in female. Lipid metabolism and over weight are closely related to elevated level of the uric acid, which might be the risk factors of uric acid abnormality in Wutai Mountain population.

ABSTRACT

Objective:To investigate the role of conjunctival impression cytology in the diagnosis of Sj?gren's syndrome (SS) and the immunological factors influencing conjunctival lesions.Methods:A total of 57 patients complaining about dry eye were collected, including 38 patients with primary Sj?gren's syndrome (pSS) and 19 patients with non-SS. Conjunctival impression cytology tests were performed for all patients, and they were scored by the Nelson method. Thirty-one patients with SS underwent serological tests such as autoantibodies, immunoglobulins, and complement. The correlation between the relevant data was compared using the t test and the rank sum test. Results:The Nelson grade ≥2 is the positive cut-off value for the diagnosis of SS. The sensitivity was 68.4%, and the specificity was 89.5%, and the area under the receiver operating characteristic curve (ROC) was 0.767. In patients with SS, there was statistical correlation between the results of conjunctival impression cytology and antinuclear antibody (ANA) ( χ2=4.664, P=0.031), anti-SSA antibody ( χ2=8.58, P<0.01), anti-SSB antibody ( χ2=6.13, P=0.013), anti-SSA-52 antibody ( χ2=6.48, P=0.011), immunoglobulin (Ig)G ( t=-4.344, P<0.01) and rheumatoid factor (RF) ( U=25.0, P<0.01). Conclusion:Con-junctival impression cytology has certain value in the diagnosis of SS and can be used to evaluate conjunctival lesions in SS. Serum ANA, anti-SSA antibody, anti-SSB antibody, anti-SSA-52 antibody, IgG, and RF levels are significantly associated with the degree of conjunctival lesions, and can be considered as an indirect evidence of conjunctival involvement in SS.

ABSTRACT

Objective To detect the anti-citrullinated alpha-enolase peptide 1 (CEP-1) antibody in rheumatoid arthritis (RA). Methods One hundred and twenty-nine patients with RA were enrolled randomly. Thirty-one patients with primary Sj?gren's syndrome (pSS), 32 patients with systemic lupus erythematosus (SLE), 32 patients with osteoarthritis (OA), and 106 healthy controls (HC) were include into this study. Anti-CEP-1 antibody was detected by enzyme-linked immunosorbent assay (ELISA). The correlations between serum anti-CEP-1 antibody and clinical features, disease activities,laboratory tests or Sharp scores of RA patients were evaluated. Mann-Whitney U test and χ2 test were used for statistical analysis. Results ①Anti-CEP-1 antibodies were positive in 64.3%(83/129) of RA patients, 22.6%(7/32) of pSS patients, 12.5%(4/32) of SLE patients, none of OA patients (0/32) or healthy controls. The positivity of anti-CEP-1 antibody was significantly higher than those in pSS ( χ2=17.7), SLE ( χ2=25.7), OA ( χ2=42.5), and healthy controls ( χ2=102.6) (P<0.01, respectively). The specificity of anti-CEP-1 antibody in RA was 94.5%. ②In patients without anti-citrullinated protein/peptide autoantibodies (ACPA), rheumatoid factor (RF) or the patients without ACPA and RF, the positive rate of anti-CEP-1 antibody was 30.3%(10/33), 41.9%(18/43) and 22.7%(5/22), respectively. ③Compared with patients without anti-CEP-1 antibodies, patients with anti-CEP-1 anti-bodies had higher rates of joint deformity, bone erosion and high disease activities (P<0.05, respectively). ④ Higher rate of interstitial lung disease (ILD) was found in RA patients with anti-CEP-1 antibody (19.3% vs 4.3%, χ2=5.494, P<0.05). ⑤The patients with anti-CEP-1 anti-body had higher rates of elevated erythrocyte sedimentation rate (ESR) ( χ2=6.543) and decreased serum albumin ( χ2=6.59), compared to patients without anti-CEP-1 antibody (P<0.05, respectively). Conclusion Anti-CEP-1 antibody has high sensitivity and specificity for RA diagnosis. Combination of anti-CEP-1 antibody with other RA antibodies might improve the early diagnosis of RA. Anti-CEP-1 antibody is significantly associated with joint damage, disease activity and pulmonary interstitial fibrosis.

ABSTRACT

Objective To evaluate the clinical value of Chinese Multi-Dimensional Health Assessment Questionnaire (MDHAQ-C) in patients with rheumatoid arthritis (RA). Methods From December 2015 to October 2016,four hundred and twelve RA patients were recruited in this study and completed the MDHAQ-C independently and routine assessment of patient index data 3 (RAPID3) was calculated. Then correlations were assessed by Spearman correlation coefficient of RAPID3 with indices of clinical relevance and disease activity to evaluate its clinical values. Results MDHAQ-C is moderately correlated with ESR (r=0.399), CRP (r=0.381), SJC (r=0.499), TJC (r=0.558) (P<0.01), but highly correlation with VAS of pain (r=0.836), VAS of global status (r=0.915) and overall assessment of physician (r=0.784)(P<0.01), and highly correlated with a Spearman's coefficient of 0.784 for DAS 28-ESR, 0.734 for CDAI and 0.682 for SDAI (P<0.001). Conclusion MDHAQ is a reliable, valid instrument for disease activity assessment and a feasible index for clinical settings in Chinese RA patients.

ABSTRACT

Objective To detect the anti-citrullinated alpha-enolase peptide 1 (CEP-1) antibody in rheumatoid arthritis (RA). Methods One hundred and twenty-nine patients with RA were enrolled randomly. Thirty-one patients with primary Sj?gren's syndrome (pSS), 32 patients with systemic lupus erythematosus (SLE), 32 patients with osteoarthritis (OA), and 106 healthy controls (HC) were include into this study. Anti-CEP-1 antibody was detected by enzyme-linked immunosorbent assay (ELISA). The correlations between serum anti-CEP-1 antibody and clinical features, disease activities,laboratory tests or Sharp scores of RA patients were evaluated. Mann-Whitney U test and χ2 test were used for statistical analysis. Results ①Anti-CEP-1 antibodies were positive in 64.3%(83/129) of RA patients, 22.6%(7/32) of pSS patients, 12.5%(4/32) of SLE patients, none of OA patients (0/32) or healthy controls. The positivity of anti-CEP-1 antibody was significantly higher than those in pSS ( χ2=17.7), SLE ( χ2=25.7), OA ( χ2=42.5), and healthy controls ( χ2=102.6) (P<0.01, respectively). The specificity of anti-CEP-1 antibody in RA was 94.5%. ②In patients without anti-citrullinated protein/peptide autoantibodies (ACPA), rheumatoid factor (RF) or the patients without ACPA and RF, the positive rate of anti-CEP-1 antibody was 30.3%(10/33), 41.9%(18/43) and 22.7%(5/22), respectively. ③Compared with patients without anti-CEP-1 antibodies, patients with anti-CEP-1 anti-bodies had higher rates of joint deformity, bone erosion and high disease activities (P<0.05, respectively). ④ Higher rate of interstitial lung disease (ILD) was found in RA patients with anti-CEP-1 antibody (19.3% vs 4.3%, χ2=5.494, P<0.05). ⑤The patients with anti-CEP-1 anti-body had higher rates of elevated erythrocyte sedimentation rate (ESR) ( χ2=6.543) and decreased serum albumin ( χ2=6.59), compared to patients without anti-CEP-1 antibody (P<0.05, respectively). Conclusion Anti-CEP-1 antibody has high sensitivity and specificity for RA diagnosis. Combination of anti-CEP-1 antibody with other RA antibodies might improve the early diagnosis of RA. Anti-CEP-1 antibody is significantly associated with joint damage, disease activity and pulmonary interstitial fibrosis.

ABSTRACT

Objective To evaluate the clinical and radiographic characteristics and function of erosive hand osteoarthritis (EOA) patients. Methods Data were obtained from 19 patients with EOA, including their social conditions, clinical conditions, radiographic scores and hand function evaluation. The number of hand osteoarthritis (HOA) patients was 312. The control group consisted of non-EOA patients with hand osteoarthritis with a ratio of 4:1 to EOA patients. A non-parameter test analysis was performed. All data were analyzed by SPSS 23.0 statistical analysis, t test, χ2 test, Fisher exact probility and Spearman's correlations analysis were used for statistical analysis. Results Totally data of 19 patients were collected. Eighteen were female. Onset age was (56±8). Average duration was 56 (12~120) months. FIHOA scores of all the EOA patients were at least 5. All the erosions of 39 joints were characteristically central and erosive changes in 7 joints (18%) showed up as gull-wing. Among 39 erosive joints, including 12 (31%) E and 27 (69%) R, 34 (87%) distal interphalangeal joints were involved. Data analysis found out that EOA patients had longer disease duration (Z=2.610, P=0.009), more severe K-L level (44 ±11 vs 26 ±7, t=7.134, P<0.01), higher AUSCAN total score (28±6 vs 21±7, t=3.781, P<0.01) and higher AUSCAN function score (18±6 vs 12±6, t=4.042, P<0.01). The differences of ESR and CRP were not significant between EOA and non-EOA patients. Conclusion Erosions seen in EOA patients are centrally located gull-wing in the DIP joints. EOA patients have longer duration, more severe radiographic damage and worse joint function.

ABSTRACT

Objective To investigate the common initial clinical presentations of primary Sj(o)gren's syndrome (pSS) with pulmonary complications,and to explore the differences between patients with extraglandular manifestations at disease onset (EGM) and those with glandular manifestations at disease onset (GM).Methods A total of 1 341 hospitalized SS patients from 2003 to 2012 were retrospectively reviewed.Of them,102 hospitalized patients with pSS'associated lung disease were analyzed and included.Case control study was performed to explore the differences between the EGM group and the GM group.Results Fifty-one percent of patients were presented with EGM at onset,with significantly shorter disease duration [36 (12,156) m vs 102 (48,159) m,x2=-2.41,P=0.016].Although the mean diagnose time was similiar,only 4% of the EGM group could be confirmed the pSS diagnose at onset,which was significantly less frequently than that of the GM group (34%,22=15.29,P<0.01).Case control study revealed that hyperglobulinemia,elevated RF titers and anti-SSA and/or anti-SSB test positive were less predominant in the EGM group [IgG 16(12,21) g/L vs 21 (15,28) g/L,x2=-2.15,P=0.032;22 (20,171) U/ml vs 104 (20,238) U/ml,x2=-l.98,P=0.048;33% vs 72%,x2=15.78,P<0.01].The predicted value of TLC and FVC were lower [(87±23)% vs (97±20)%,x2=-1.96,P=0.050;(8±28)% vs (100±27)%,x2=-1.70,P=0.089] and HRCT score was higher in EMG group [12(88,15) vs 8(5,13),x2=-1.82,P=0.070].Conclusion EMG at onset is the common initial manifestation of pSS'associated lung involvement.Pulmonary complication is more progressively and severe than those with MG at onset.Anti'SSA positive,elevated RF titer and hyperglobulinemia are not predominant for patients with EMG at onset.

ABSTRACT

Objective To reduce the misdiagnosis rate of spondyloarthritis (SPA) by reviewing the rare cases misdiagnosed as SpA.Methods Cases misdiaguosed as SpA were collected from our hospital from January 2004 to April 2014.Reported cases among Chinese journals from January 1998 to October,2014 were also collected.According to the Assessment of Spondylo Arthritis international Society (ASAS) axial SpA criteria (2009) and peripheral SpA criteria (2011),the diagnostic accordance rate was studied.Results There were 112 cases within the objective scope,out of which,27 cases (24.1%) were infectious diseases,47 cases (42.0%) were heredity and metabolic diseases,25 cases (22.3%) were hematonosis or tumor,13 cases (11.6%) were osteoarthropathies.Also,only 10 cases (8.9%) out of 112 had the symptoms of inflammatory back pain (IBP),23 cases (20.5%) exhibited fever.Human leukocyte antigen (HLA)-B27 was positive in 20.4% (21/103) of the cases.Eleven cases out of those 29 cases performed X-ray in the sacroiliac joint and showed blurred articular surface,narrowing of joint space or bone destruction.Four cases were diagnosed based on magnetic resonance imaging (MRI).18/91 (19.8%) cases met the criteria of ASAS axial SpA criteria (2009),2/6(33.3%) cases were in accordance to the ASAS peripheral SpA criteria (2011).Conclusion For patients with atypical back pain,if accompanied with fever,other diseases such as tumor,infection,heredity and metabolic diseases should be considered.The diagnosis should not only based on HLA-B27 for SpA diagnosis.Due to the ambiguity of X-ray in sacroiliac joint,CT or MRI may be recommended to assist the diagnosis.Careful clinical history taken is also with great significance.

ABSTRACT

Objective To investigate the clinical and laboratory features of autoimmune disease (AID) associated cryoglobulinaemia. Methods From April 2010 to May 2014, thirty threc patients with AID in Peking University Peopleˊs Hospital were tested positive for cryoglobulin. Their clinical and laboratory features were analyzed retrospectively. T test, Mann-Whitney U test, Chi-squaretest and Fisherˊs exact test were used for statistical analysis. Results Among the 33 patients, 26 were female, 7 were male, the average age was (47 ± 17) years old (range 12-75 years old). The spectrum of autoimmune diseases included, in order, systemic lupus erythematosus (SLE), Sj?grenˊs syndrome (SS), multiple myositis/dermatomyositis, rheumatoid arthritis (RA), systemic sclerosis (SSc), anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis, antiphospholipid syndrome and primary biliary cirrhosis. SLE and SS accounted for 84.8% (28/33) in tpatients with cryoglobulinaemia. In patients withSLE, cryoglobulinaemia occurred at 2.0 (1.0-12.0) years after disease onset, and cryoglobulinpositive patients had more frequent renal involvement (71% vs 40%, P=0.004), positive anti-RNP (56% vs21%, P=0.007) and ACL (53% vs 8%, P=0.000). However, among patients with SS, cryoglo-bulinaemia occurred at 11.0 (4.0-18.0) years after disease onset, and cryoglobulin positive patients had higher rheumatoid factors (RF) [1 170 (230.00, 2 800.00) U/ml vs 57.80 (20.00, 230.50) U/ml, U=-0.002, P=0.001], IgM [3.54 (1.83, 4.34) g/L vs 1.17 (0.81, 2.26) g/L , U=0.016, P=0.014] and lower complement C3 [0.58 (0.33, 0.68) g/L vs 0.81 (0.67, 0.98 g/L), U=0.004, P=0.003] and C4 [0.06 (0.03, 0.12) g/L vs 0.16 (0.12, 0.22), U=0.017, P=0.016]. Conclusion Autoimmune disease complicated with cryoglo-bulinaemia is not uncommon in clinical practice, in which SLE and SS account for the leading two causes. Patients with positive anti-RNP and/or ACL are positively associated with cryoglobulinaemia. renal involvement of SLE is increased by the presence of cryoglobulin.
