OBJECTIVETo observe the effect of Xinfeng Capsule (XFC) on ankylosing spondylitis (AS) patients' symptoms and signs, serum immunoglobulin levels, peripheral blood lymphocyte autophagy protein, autophagy gene, and to explore its mechanism.

METHODSTotally 59 AS patients were assigned to the treatment group (39 cases) and the control group (20 cases) according to random digit table. Patients in the treatment group received XFC, 0.5 g each pill, three pills each time, 3 times per day, while those in the control group received sulfasalazine (SASP), 0.25 g per tablet, 4 tablets each time, twice per day. Three months consisted of one therapeutic course. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI) were statistically calculated. Serum immunoglobulins (IgG1, IgG2, IgG3, IgG4, IgA , SIgA, and IgM) were detected using ELISA. Changes of Beclin1, LC3-II, phosphatidylinositol 3-kinase (PI3K), Akt, the mammalian target of rapamycin (mTOR) were detected using Western blot. Serum autophagy related genes such as Atg1, Atg5, Atg12, Atg13, and Atg17 were detected using the polymerase chain reaction (PCR). The correlation between immunoglobulin subtypes and autophagy gene in AS patients using Spearman correlation.

RESULTSCompared with before treatment, BASDAI, IgG1, lgG3, and IgA decreased (P < 0.01); PI3K, Akt, and mTOR protein expressions decreased (P < 0.01); ATG1, ATG12, ATG13, and ATG17 mRNA expressions decreased, ATG5 mRNA expression increased (P < 0.01) in the treatment group. But BASDAI, IgG1, and IgA levels decreased (P < 0.05, P < 0.01); PI3K, Akt, and mTOR protein expressions decreased (P < 0.05); ATG1 and ATG13 mRNA expressions decreased (P < 0.05, P < 0.01) in the control group. Compared with the control group, BASDAI, IgG1, and IgA levels decreased (P < 0.05); PI3K, Akt, mTOR protein expressions decreased (P < 0.01); ATG12 and ATG17 mRNA expression decreased, ATG5 mRNA expression increased (P < 0.01) in the XFC group. Correlation analysis showed AS patients' IgG1, IgG2, IgG3, IgA, SIgA, IgM had negative correlation with ATG17; IgG4 and ATG17 were positively correlated (P < 0.05, P < 0.01).

CONCLUSIONXFC could elevate clinical efficacy of AS patients and enhance their autophagy, which might be achieved by acting on PI3K/Akt/mTOR signal, affecting autophagy gene and autophagy protein expression, taking part in the regulation of proliferation and differentiation of lymphocyte B, and strengthen humoral immunity.

OBJECTIVETo evaluate the short-term efficacy and safety of Bushen Shuji Granule (BSG) in treating ankylosing spondylitis (AS) patients.

METHODSA prospective randomized controlled clinical trial was carried out in 62 active stage AS patients with Shen deficiency Du-channel cold syndrome (SDDCS), who were randomly assigned to the BSG group (treated with BSG) and the control group (treated with Celecoxib Capsule). Twelve weeks consisted of one therapeutic course. Therapeutic effects were evaluated by ASAS20 and ASAS40 (set by Assessments in Ankylosing Spondylitis working group) , BASDA150, Chinese medical (CM) syndrome efficacy evaluation standards. BASDAI, the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath AS Metrology Index (BASMI), scores for spine pain, scores for pain at night, patient global assessment (PGA) , erythrocyte sedimentation rate (ESR) , and C reactive protein (CRP) were observed before and after treatment.

RESULTSAfter three-month treatment by BSG, ASAS20 standard rate was 63. 33% (19/30 cases) in the BSG group and 66.67% (20/30 cases) in the control group with no significant difference between the two groups (χ2 = 0.073, P > 0.05). The efficacy for CM syndromes was 70.00% (21/30 cases) in the BSG group, higher than that in the control group [40.00% (12/30 cases), χ2 = 5.455, P < 0.05]. Scores for CM syndromes, BASDAI, night pain index, spinal pain index, PGA, CRP were improved in the BSG group (P < 0.05, P < 0.01). The incidence of adverse events in the BSG group was lower than that of the control group.

CONCLUSIONBSG based on Shen supplementing, Du-channel strengthening, blood activating, and channels dredging method had good short-term clinical efficacy and safety in treating AS.

OBJECTIVETo evaluate the clinical efficacy and safety of Qiangji Recipe (QR) in ad- junctive treatment of axial undifferentiated spondyloarthritis (axuSpA) through a four-week open study.

METHODSFifty-four axuSpA patients of Shen-deficiency Du-channel cold syndrome (SDDCS) in line with inclusive criteria were recruited and assigned to the treatment group and the control group according to random digit table, 27 in each group. Patients in the control group took Celecoxib Capsule (0.2 g each time, twice per day). Patients in the treatment group additionally took QR (consisting of Herba Epimedii 15 g, antler glue 15 g, Cibotium Barometz 15 g, eucommia bark 20 g, dipsacus asper 10 g, two toothed achyranthes root 15 g, drynaria 15 g, Taxillus Chinensis 20 g, ground beetle 10 g, scorpion 5 g, wild celery 10 g, notopterygium incisium 10 g, cow-fat seed 10 g, white mustard seed 6 g, and licorice root 6 g, one dose per day, twice daily). The therapeutic course for all was 4 weeks. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath AS Metrology Index (BASMI), total body pain and spinal pain, patient and physician global assessment on a four-point scale, the Ankylosing Spondylitis Quality of Life (ASQoL), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured before and after 4 weeks of treatment. The primary end point in this study was the proportion of patients with a 20%improvement response accord- ing to the ASAS International Working Group Criteria (ASAS 20 responders) at week 4.

RESULTSTotally 50 patients completed this trial, 26 in the treatment group and 24 in the control group. Improvement of BASDAI, BASFI, BASMI, ASQoL, ESR, and CRP was shown in both groups after treatment. Better effect was shown in the treatment group in all indices except ESR and BASMI after treatment (P < 0.05, P < 0.01). Twenty cases (accounting for 76.92%) in the treatment group achieved ASAS 20 response at week 4, while 12 cases (accounting for 50.00%) in the control group achieved ASAS 20 response at week 4 (P < 0.05). No obvious adverse reaction occurred in the two groups.

CONCLUSIONQR combined Celecoxib Capsule showed better effect in treating axuSpA patients than using Celecoxib Capsule alone.

OBJECTIVETo explore changes of B and T lymphocyte attenuator (BTLA), superoxide dismutase (SOD), catalase (CAT), total antioxidant capacity (TAOC), reactive oxygen species (ROS), reactive nitrogen species (RNS), malondialdehyde (MDA) in ankylosing spondylitis (AS) patients, and the effect of Xinfeng Capsule (XFC) on them.

METHODSTotally 120 AS patients were assigned to two groups according to random digit table method, the XFC group (3 XFC pills each time, 3 times a day) and the SASP group (4 SASP tablets each time, twice a day), 60 in each group. All patients were treated for 3 months. Another 60 healthy subjects were recruited as a healthy control group. The expression frequency and activation levels of BTLA were detected using flow cytometry. Serum oxidative stress indices (such as SOD and CAT, TAOC, ROS, RNS, MDA) and contents of cytokines [tumor necrosis factor α (TNF-α), IL-1β, IL-4, and IL-10] were detected using enzyme-linked immunoassay (ELISA). Erythrocyte sedimentation rate (ESR) was detected using Westergren method. High-sensitivity C-reactive protein (Hs-CRP) was detected using HITACHI 7060 type automatic biochemical analyzer. Clinical efficacies of ASAS 20 and BASDAI50 were assessed using VAS. Correlation analysis between scoring for quality of life and BTLA expression frequency was performed.

RESULTS(1) Clinical efficacies of ASAS 20 and BASDAI50 were significantly better in the XFC group than in the SASP group (P < 0.01). (2) Compared with the healthy control group, BTLA expressions in the peripheral blood of AS patients decreased significantly (P <0. 05); SOD, CAT, and TAOC values significantly decreased (P < 0.01, P < 0.05); ROS, RNS, and MDA values significantly increased (P < 0.01, P < 0.05); TNF-α, IL-1β, ESR, and Hs-CRP values significantly increased (P < 0.01); IL-4 and IL-10 values decreased significantly (P < 0.01, P < 0.05). (3) Compared with pre-treatment in the same group, BTLA/CD19 + B, BTLA/CD24 + B, SOD, TAOC, IL-4, SF-36 [physical functioning (PF), social functioning (SF), role limitation due to physical problems (RP), role limitation due to emotional problems (RE), body pain (BP), mental health (MH), vitality (VT), general health (GH)] were significantly elevated; ROS, MDA, TNF-α, ESR, Hs- CRP, VAS, BASDAI and BASFI, BAS-G were significantly lower in the peripheral blood of the two groups after treatment (P < 0.01, P < 0.05). Better effect was shown in the XFC group in elevating BTLA/CD19+ B, BTLA/CD24 + B, SOD, TAOC, IL-10, BP, MH, VT, and SF; and lowering ROS, IL-1β, MDA, TNF-α, ESR, Hs-CRP, VAS, BASDAI, BASFI, and BAS-G (P < 0.01, P < 0.05). (4) Pearson correlation analysis showed, BTLA/CD19 + B expression of the peripheral blood was positively correlated with SOD, CAT, TAOC, IL-4, IL-10, GH, RP, BP, and SF (r = 0.431, 0.325, 0.318, 0.316, 0.348, 0.314, 0.358, 0.318, 0.326, respectively, P < 0.05, P < 0.01), while it was negative correlated with ROS, MDA, TNF-α, IL-1β, ESR, VAS, and BASDAI (r = -0.342, -0.368, -0.334, -0.354, -0.324, -0.372, -0.342, respectively, P < 0.05, P < 0.01). BTLA/CD24 B expression of the peripheral blood was positively correlated with SOD, TAOC, IL-4, IL-10, GH, RP, BP, SF, RE, MH, VT (r = 0.358, 0.352, 0.372, 0.436, 0.435, 0.326, 0.352, 0.345, 0.326, 0.343, 0.332, respectively, P < 0.05, P < 0.01), while it was negative correlated with ROS, RNS, MDA, ESR, Hs-CRP, VAS, BASDAI, and BASFI (r = -0.447, -0.336, -0.405, -0. 395, -0. 358, -0.436, -0.338, -0.425, respectively, P < 0.05, P < 0.01).

CONCLUSIONXFC could improve BTLA expression in the peripheral blood of AS patients, negatively regulate activation and proliferation of B cells, and reduce abnormal immune responses and oxidative stress injury, thereby effectively alleviating joint stiffness and pain.

We evaluated the utility of follow-up interferon-gamma release assays (IGRAs) for the diagnosis of reactivation of latent tuberculosis infection (LTBI) or new tuberculosis in ankylosing spondylitis (AS) patients receiving anti-tumor necrosis factor alpha (anti-TNFalpha). The study participants (n=127) had a negative IGRA screening before receiving anti-TNFalpha and were evaluated by follow-up IGRA. We retrospectively examined data of the subjects according to age, gender, tuberculosis prophylaxis, concomitant medications, IGRA conversion and anti-TNFalpha, including type and treatment duration. The median duration of anti-TNFalpha was 21.5 months, and the median age was 35.3 yr. Of the 127 patients, IGRA conversion was found in 10 patients (7.9%). There was no significant variation between IGRA conversion rate and any risk factors except for age. IGRA conversion rate was not significantly different between AS and rheumatoid arthritis (P=0.12). IGRA conversion was observed in AS patients receiving anti-TNFalpha in Korea. A follow-up IGRA test can be helpful for identifying LTBI or new tuberculosis in AS patients receiving anti-TNFalpha.

OBJECTIVETo confirm the efficacy and safety of Jitongning Capsule in the treatment of ankylosing spondylitis (AS).

METHODSA total of 120 AS patients with early-intermediate were randomly and equally assigned to Jitongning Capsule group and sulfasalazine group. Jitongning Capsule was orally taken 4.5 g per day and sulfasalazine was orally taken 2 g daily for 12 months. The primary endpoint was the proportion of patients achieving the Assessment in Ankylosing Spondylitis 20 (ASAS 20), secondary end points included Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrology Index (BASMI), patient's global assessment by VAS rating, spinal pain, general pain and night pain, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ) and interleukin-4 (IL-4) in the peripheral blood mononuclear cells (PBMC) of AS patients were measured.

RESULTSA total of 111 patients completed the study. There were 58 patients in Jitongning group and 53 patients in sulfasalazine group. Both drugs showed mild and occasional side effects. After treated by Jitongning Capsule and sulfasalazine, the proportion of ASAS20 responders at 12 month was 72.41% (42/58) and 67.92% (36/53) respectively. Both Jitongning Capsule and sulfasalazine treatment induced significant decrease in the proportion of CD4(+)T cell and CD8(+)T cell expressing TNF-α and IFN-γ at 12-month of treatment compared with baseline values (P<0.05).

CONCLUSIONJitongning Capsule are effective in a setting close to real-life medical care with a sustained improvement in signs and symptoms of AS, and reduce cytokine levels in PBMC. It showed comparable effects to sulfasalazine.

OBJECTIVEIn order to investigate the roles of metalloproteinase in inflammatory bone destruction in ankylosing spondylitis (AS), and analyze the mechanism of preventing inflammatory bone destruction of Bushen Qiangdu decoction (BSQDD) in AS cases. Comparisons were made on the expressions of matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of metalloproteinase 1 (TIMP-1) by peripheral blood mononuclear cells (PBMC) between AS patients and healthy controls. The effect of BSQDD was investigated on the expression and of MMP-9 and TIMP-1 produced by PBMC in AS patients.

METHODSFrom March 2005 to March 2006, 30 active AS cases of Kidney-asthenia, Du-cold and blood-stasis syndrome were selected as patients group in the China-Japan Friendship Hospital. There are 27 male patients and 3 female patients. The age range is from 16 to 45, averaging (30.8 +/- 8.8) years. Disease duration is from 0.5 to 10 years. Cases received three-month BSQDD treatment were considered as the treatment group. Twenty healthy persons were included in the control group. Serum and PBMC were separated. The PBMC were stimulated by PHA and PMA, and the supernatant was collected. The mRNA expression of MMP-9 and TIMP-1 in PBMC was analyzed by RT-PCR. The content of MMP-9 and TIMP-1 in serum and culture supernatant of PBMC were detected by ELISA.

RESULTSCompared with health control group, the serum concentration of MMP-9 and TIMP-1 in patients group before treatment increased (P<0.01, P<0.05), but the level of MMP-9 and TIMP-1 in the serum of patients after treatment decreased compared with pre-treatment cases (P<0.05). Furthermore,compared with health control group, PBMC of patients group before treatment expressed higher levels of MMP-9 and TIMP-1 both on transcript level and at protein level (P<0.01, P<0.05), and the expression levels of MMP-9 and TIMP-1 in PBMC in patients after treatment both on transcript level and at protein level was down-regulated compared with pre-treatment (P<0.01, P<0.05).

CONCLUSIONPBMC of AS patients had a higher potential capacity for MMP-9 and TIMP-1. BSQDD possibly prevented inflammatory bone destruction of AS through inhibiting production of MMP-9 and TIMP-1 produced by PBMC.

BACKGROUND: We assessed the efficacy of serial interferon-gamma release assays (IGRAs) for the diagnosis of latent tuberculosis infection (LTBI) in patients receiving immunosuppressive agents for treatment of rheumatic diseases in Korea. METHODS: Of 276 patients who underwent consecutive screening with one of two IGRAs [QuantiFERON-TB Gold or QuantiFERON-TB Gold In-Tube], 66 patients were evaluated by the serial IGRA for detection of LTBI during therapy with immunosuppressive agents. Information on clinical diagnosis, medication, previous TB, blood cell count, tuberculin skin test, and interferon-gamma (IFN-gamma) level measured by IGRA was collected. RESULTS: Of the 66 patients, the initial IGRA was positive in 24.2%, negative in 65.2%, and indeterminate in 10.6%. Forty-six patients (69.7%) showed consistent IGRA results during follow-up, and 13 patients (19.7%) had consistently positive results. IGRA conversion rate was 12.1% (8/66) and reversion rate was 4.5% (3/66). Conversion of IGRA results was only observed in ankylosing spondylitis patients, and the median interval between the two tests in patients with conversion was 8.5 months. The mean IFN-gamma level in the group of patients with consistently positive IGRA results was higher than that in the group with inconsistently positive results, although this trend was not statistically significant (P=0.293). Indeterminate results were observed most frequently in patients with systemic lupus erythematosus. CONCLUSIONS: In patients receiving immunosuppressive agents, both IGRA conversions and reversions were observed. Serial IGRA testing may not be needed in patients with a positive initial IGRA result showing high IFN-gamma levels, because of high consistency in the test results.

BACKGROUND: This review evaluated the safety and efficacy of etanercept in patients with ankylosing spondylitis (AS). METHODS: Of 59 patients with AS, this study reviewed 11 patients who were refractory to conventional therapy and treated with etanercept from September 2005 to January 2008. The mean follow-up duration was 13.6 months. The general improvement was evaluated by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and adverse effects, complications and inflammatory markers were also assessed. RESULTS: The mean BASDAI decreased from 7.1 +/- 1.6 before treatment to 4.2 +/- 1.8 at 3 months after the etanercept treatment (p = 0.001). The mean erythrocyte sedimentation rate and C-reactive protein were decreased significantly by the etanercept treatment. The greatest improvement in symptoms was enthesitis, followed by skin involvement and morning stiffness. There was a significant difference in the improvement in BASDAI along with the follow up duration (p = 0.04). A serious infection was observed as a complication in 1 case. CONCLUSIONS: These results suggest that etanercept can induce significant improvement in most patients with less damage. A trial of tumor necrosis factor inhibition is indicated in all AS patients who do not achieve adequate disease control with disease-modifying antirheumatic drugs, such as methotrexate, leflunomide etc. The patients treated with etanercept should be educated about the possibility of infection and monitored closely.
