ABSTRACT

<p><b>BACKGROUND</b>Previous studies indicate that CD43 plays a role in regulating the adhesion of lymphocytes, cell mutation and activation, however, little is known about its effect on systemic lupus erythematosus (SLE). This study was designed to explore the clinical significance of CD43 in SLE patients.</p><p><b>METHODS</b>We used microarray and real-time PCR to detect the mRNA and protein expression of magnetic bead sorted T cells and B cells from peripheral blood mononuclear cells (PBMCs) of SLE patients, and analyzed the relationship between CD43 and the clinical indexes.</p><p><b>RESULTS</b>Both microarray and real-time PCR results showed that CD43 mRNA was significantly decreased in PBMCs of SLE patients compared with healthy controls (P < 0.001). There were no significant differences between lupus nephritis and non-lupus nephritis patients, and neuropsychiatric and non-neuropsychiatric patients. CD43 mRNA expression was significantly reduced in T cells but not in B-cells in SLE patients compared to healthy controls (P < 0.01). Compared with healthy controls, the percentage of CD43(+) cells in the PBMCs of SLE was significantly decreased (P = 0.004), and the CD43 fluorescence intensity in CD3(+)/CD43(+) cells and CD19(+)/CD43(+) cells was also significantly weaker than in healthy controls (P = 0.039 and 0.003). There was no significant difference in the percentage of CD3(+)/CD43(+) cells, CD19(+)/CD43(+) cells between the two groups. The CD43 fluorescence intensity in CD3(+)/CD43(+) cells was inversely correlated with the levels of IgG and IgM (r = -0.8 and -0.6).</p><p><b>CONCLUSIONS</b>Compared to healthy controls, both CD43 mRNA and protein expressions were reduced in T cells from patients with SLE, and were inversely correlated with IgG.</p>

ABSTRACT

<p><b>BACKGROUND</b>p53 is a tumor suppressor and plays a key role in regulating cell hyperplasia, repairing DNA and inducing apoptosis. This study was to investigate p53 expression in fibroblast-like synoviocytes (FLS) and its effect on CD4(+) T lymphocytes from patients with active rheumatoid arthritis (RA).</p><p><b>METHODS</b>Human FLS were transfected with p53 siRNA and cocultured with CD4(+) T lymphocytes from patients with active RA. The expressions of osteoprotegerin and interleukin (IL)-6 were detected in p53 siRNA and scramble siRNA-transfected FLS. In addition, protein levels of interferon (IFN)-γ, IL-17, IL-4 and CD25 as well as mRNAs of IFN-γ, retinoic acid-related orphan receptor (ROR)-γt, IL-17 and Foxp3 in cocultured CD4(+) T lymphocytes were also measured.</p><p><b>RESULTS</b>IL-6 decreased in p53-knockdown FLS while osteoprotegerin expression was not altered. FLS with p53 deletion significantly increased the production of IL-17 and IFN-γ by CD4(+) T cells and upregulated Foxp3 mRNA expression without effects on the proportion of CD4(+)CD25(high) T lymphocytes.</p><p><b>CONCLUSION</b>p53 in FLS might regulate Th1 and Th17 functions in patients with RA and participate in the pathogenesis of RA.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To assess the prevalence of anti-alpha-enolase antibody in systemic autoimmune diseases in Chinese patients and its role in endothelial cell apoptosis.</p><p><b>METHODS</b>The reactivity of anti-alpha-enolase antibody in a variety of autoimmune disorders in Chinese patients was evaluated by dot blot assay. Endothelial cell apoptosis was investigated by in vitro incubation of endothelial cells with IgG purified from anti-alpha-enolase antibody-positive sera, with or without pre-incubation with recombinant alpha-enolase.</p><p><b>RESULTS</b>Anti-alpha-enolase antibody was prevalent in different systemic autoimmune diseases with relatively high reactivity in Chinese patients. In vitro incubation of endothelial cells with IgG containing anti-alpha-enolase antibody induced apoptosis in a time- and dose-dependent manner. Apoptosis was partly inhibited by pre-incubation of the endothelial cells with recombinant alpha-enolase.</p><p><b>CONCLUSIONS</b>Our data suggest that alpha-enolase is a common auto-antigen recognized by anti-endothelial cell antibodies in connective tissue disease. Interaction between alpha-enolase and its autoantibody plays a role in endothelial cell apoptosis. Changes other than cell killing may contribute to the pathogenesis of endothelial damage and microvascular lesions.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the dynamic changes of lymphocyte subsets before and after autologous hemopoietic stem cell transplantation (HSCT) in severe/refractory autoimmune disease (AID) and study the post-transplantation immunological reconstitution in AID.</p><p><b>METHODS</b>Thirteen patients with severe/refractory AID who registered for HSCT from April 2003 to April 2005 in Peking Union Medical College Hospital, including 8 patients with systemic lupus erythematosus, 4 patients with rheumatoid arthritis, and 1 patient with primary Sjögren's syndrome (pSS) were enrolled in this study. Blood samples were collected before/after mobilization, before conditioning, and 2 weeks, 1 month, 3 months, 6 months, 12 months, and 18 months post-transplantation. Lymphocyte subsets were tested by flow cytometry as follows: T cell (CD3 +), B cell (CD19 +), natural killer (CD3-CD16 + CD56 +), Th (CD3 + CD4 +), Tc (CD3 + CD8 +), naïve T (CD4 + CD45RA), memory T (CD4 + CD45RO), and CD4/CD8 ratio.</p><p><b>RESULTS</b>Lymphocyte subsets for SLE patients were severely abnormal compared to normal or RA patients (both P < 0.01). B cell reconstituted to normal level within 18 months, meanwhile NK and T cell remained low. The repopulations of Th and naive T cell were delayed, which caused the up-side-down of CD4/CD8 ratio and low level of naYve T cell percentage for a relatively long time.</p><p><b>CONCLUSIONS</b>Lymphocyte subsets abnormality in SLE patients are more severe than in RA patients. Although most autoimmune T/B cell in the grafts and patients can be effectively removed after transplantation, nonmyeloablative conditioning may be a risk for the relapse of AID. The long-term inhibition of CD4 + T cell may be related with the relief of AID after transplantation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the feasibility and safety of peripheral CD34+ cell mobilization in patients with severe autoimmune disease.</p><p><b>METHODS</b>Forty-two patients underwent a total of 46 mobilizations by the regimen of cyclophosphamide 2-3 g/m2+ recombinant human granulocyte colony stimulating factor (rhG-CSF) 5 microg x kg(-1) x d(-1). The positive selection of CD34+ cell was performed through the CliniMACS.</p><p><b>RESULTS</b>In 8.1 +/- 2. 3 days after administration of cyclophosphamide, the peripheral white blood cell and mononuclear cell (MNC) decreased to the lowest level. In 3.7 +/- 1.6 days after injection of rhG-CSF, the peripheral absolute MNC and CD34+ cell counts were 0.95 x 10(9)/L and 0.035 x 10(9)/L, respectively. After 2.4 +/- 0.6 times of leukapheresis, there gained 4.46 x 10(8)/kg of MNC and 5.26 x 10(6)/kg of CD34+, respectively. After mobilization, the underlying diseases were ameliorated more or less. In systemic lupus erythematosus (SLE) patients, SLE Disease Activity Index (SLEDAI) decreased from a median of 17 to 3 (P < 0.01). In rheumatic arthritis patients, an American College of Rheumatology criteria for 20% (ACR20) response was achieved in all five patients. Totally, 17.4% of patients whose absolute neutrophil count < 0.5 x 10(9)/L suffered infection, and 31.0% of patients had bone pain after the injection of rhG-CSF. Two patients suffered severe complications, one with acute renal failure and recovered by hemodialysis, the other died of thrombotic thrombocytopenic purpura. Failed mobilization occurred in three patients.</p><p><b>CONCLUSIONS</b>Sufficient CD34+ cells can be mobilized by low dose of cyclophosphamide and rhG-CSF. CD34+ cell mobilization for treatment of severe autoimmune disease not only is appropriate in both effectiveness and safety but ameliorates disease also.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of diacerein in patients with knee osteoarthritis (OA).</p><p><b>METHODS</b>A total of 223 patients satisfying the American College of Rheumatology criteria for knee OA were chosen for this 17-week, randomized, double-dummy, diclofenac sodium-controlled trial, with diacerein dosage of 100 mg/d and diclofenac sodium of 75mg/d. Efficacy and safety of both drugs were evaluated.</p><p><b>RESULTS</b>Totally 106 patients in the diacerein group and 107 patients in the diclofenac group were considered qualified for the evaluation. After 12 weeks of treatment, the total effective rates of patients/physicians' overall assessment in diacerein and diclofenac groups were 65.4%/61.6% and 61.2%/61.2%, respectively (P > 0.05). The primary efficacy parameter [visual analog scale (VAS) assessment of pain on 20 metres walking] and the secondary efficacy parameters [tenderness on palpation, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and 36-item Short-Form (SF-36) Health Survey] significantly improved compared with baseline in both groups (P < 0.05). In the follow-up period, there were no obvious changes in above parameters in diacerein group. However, in diclofenac group, pain on 20 metres walking, tenderness on palpation, and WOMAC became aggravated after withdrawing the drug for 4 weeks (P < 0.05). Moreover, the consumption of paracetamol was significantly lower in diacerein group than in diclofenac group during follow-up (P < 0. 001). The incidences of related adverse events were 35.7% in diacerein and 45.1% in diclofenac group, respectively. Mild-to-moderate gastrointestinal disorders were the most frequent adverse events.</p><p><b>CONCLUSIONS</b>Diacerein is as effective as diclofenac sodium in treating patients with knee OA. Furthermore, it has better extended effect and a good safety profile. It is generally well tolerated and has no severe adverse effect.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the feasibility, efficacy, and safety of high dose immunosuppressive therapy (HDIT) and autologous hemopoietic stem cell transplantation (HSCT) with CD34+ cell selection in patients with severe, refractory autoimmune diseases.</p><p><b>METHODS</b>Twenty-six patients with persistent systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), primary Sjögren's syndrome (pSS), or systemic sclerosis (SSc) who had been treated unsuccessfully with conventional treatment were enrolled in the trial in Peking Union Medical College Hospital from September 1999 to June 2004. The patients received HDIT with 200 mg/kg cyclophosphamide followed by an infusion of autologous stem cells that were CD34 selected. Disease activity, adverse effect, hemopoietic and immune reconstitution, and time to recurrence of disease were monitored.</p><p><b>RESULTS</b>Overall treatment related mortality was 7.7% (2/26) with 1 patient died of cytomegalovirus infection and another of severe pneumonia. Relapse occurred in 3 SLE patients (17.6%) in 37, 26, and 19 months posttransplantation respectively, and 1 RA patient in 15 months posttransplantation. SLE Disease Activity Index (SLEDAI) scores of SLE survivors decreased significantly (P < 0.01). RA patients recorded a drop of Disease Activity Score 28 (DAS 28). The pSS patient remained symptoms free up to now, more than 50 months after the transplantation.</p><p><b>CONCLUSION</b>HSCT can be performed relative safely in patients with severe autoimmune disease. Short-term effect of HSCT is promising. However treatment related mortality and relapse were observed in a subset of patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the inhibition mechanisms of BAY11-7082 (IkappaB-alpha phosphorylation inhibitor) and Lactacystein (proteosome inhibitor) in CD154-induced NF-kappaB activation.</p><p><b>METHODS</b>We used recombinant CD154 to stimulate EBV/LMP1 negative Ramos B cell and observed the effects of BAY11-7082 and Lactacystein in CD154-induced NF-kappaB luciferase activation, phosphorylation and degradation of IkappaB-alpha, phosphorylation of p65, and nuclear translocation of NF-kappaB subunits upon CD154 stimulation.</p><p><b>RESULTS</b>Both BAY11-7082 and Lactacystein abrogated CD154-induced NF-kappaB luciferase activation in Ramos cells. While CD154-induced phosphorylation of p65, phosphorylation and degradation of IkappaB-alpha, and nuclear translocation of p50, p65, and c-Rel were all blocked by BAY11-7082; Lactacystein only inhibited degradation of IkappaB-alpha and p65 nuclear translocation.</p><p><b>CONCLUSION</b>BAY11-7082 and Lactacystein inhibit CD154-induced NF-kappaB activation through different mechanisms.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the feasibility of autologous peripheral CD(34)(+) cell transplantation for the treatment of severe autoimmune disease.</p><p><b>METHODS</b>Ten patients received mobilized and purified CD(34)(+) cells transplantation. The mobilization regimen was CTX plus rhG-CSF and the CD(34)(+) cells were selected by CliniMACS. (1.98 +/- 0.95) x 10(8) CD(34)(+) cells were obtained. The purity of CD(34)(+) cells was (91.4 +/- 10.6)% and the recovering rate was (60.5 +/- 19.8)%. The conditioning regimens were CTX (200 mg/kg) plus ATG (90 mg/kg) or CTX (150 mg/kg) plus TBI (4 - 6 Gy). (2.14 +/- 1.05) x 10(6)/kg CD(34)(+) cells were infused. The time of ANC >or= 0.5 x 10(9)/L was 8.6 +/- 2.5 days, and platelet >or= 20 x 10(9)/L was 9.0 +/- 5.2 days. After the hematopoietic recovery, the levels of CD(3)(+) T cell, CD(19)(+) B cells and CD(16)(+)CD(56)(+) NK cells were all below that of pre-transplantation. The main transplant-related complication was CMV infection. The transplant-related mortality was 2/10. All patients who survived showed improvement of the disease with DAI score decreasing from 17 to 4 in systemic lupus erythematosus patients, DAS 28 score from 6.4 to 1.8 in rheumatoid arthritis patients.</p><p><b>CONCLUSION</b>The result suggests that autologous peripheral CD(34)(+) cell transplantation is an alternative choice for the treatment of severe autoimmune disease. The short-term outcome is satisfying.</p>

ABSTRACT

Objective To analyze the clinical and immunological manifestations of antiphospholipid syndrome(APS)in a cohort of 100 patients.Methods The clinical and serologic features of APS(Sapporo preliminary criteria)in 100 patients were analyzed retrospectively.Results The cohort consisted of 79 female patients and 21 male patients witb a mean age of 36?13 years at diagnosis.Primary APS was presented in 37% of patients;APS was secondary to systemic lupus erythematosus(SLE)in 46%,lupus-like syndrome in 14%. Eighty percent of the patients had thrombosis,43(54%)patients had venous thrombosis,18(22%)had arterial thrombosis,15(19%)had both arterial and venous thrombosis.4(5%)had thrombosis of microcirculation. Forty-two(52%)patients presented thrombosis at a single site,26(32%)at two sites,12(15%)at three or more sites.Forty-five(56%)patients experienced one thrombotic episode,20(25%)patients had only one re- currence,and 15(19%)had more thrombosis.The most common manifestations of thrombosis were deep vein thrombosis(36%),pulmonary embolism(30%)and stroke(26%),with heart,kidney,gastrointestinal tract and other organs involvements.Thirty-four(51%)female patients had spontaneous fetal losses including intrauter- ine fetus death and recurrent spontaneous abortion.Seventy-one(71%)patients developed thromboeytopenia. The presence of antieardiolipin antibody(ACL)was detected in 84 patients(84%).Among 90 patients with APS,alone ACL was detected in 38 patients(42%),both ACL and lupus anticoagulant(LA)were detected in 36(40%),LA alone in 16(18%).Patients with APS associated with SLE or lupus-like syndrome had higher frequency of arthritis,leukopenia,antinuclear antibodies(ANA)and low complement levels.Female patients had a higher frequency of leukopenia,ANA and ACL.Male patients had a higher prevalence of deep venous thrombosis in the lower limbs and LA.Conclusion APS is an autoimmune disorder characterized by recurrent arterial and venous thrombosis,fetal loss,or thrombocytopenia with the presence of ACL and/or LA.In APS secondary to with SLE,the patient's sex can modify the disease expression and define specific subsets of APS.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate whether interferon-inducible protein 10 (IP-10) is involved in the inflammatory process of the labial gland of patients with Sjogren's Syndrome (SS).</p><p><b>METHODS</b>Forty-nine patients performed labial gland biopsy, the number of lymphocytes in the biopsy tissues was calculated and the IP-10 was detected by the methods as following: 39 biopsied labial tissues were examined by RT-PCR, among them, 21 were from primary SS, 5 from secondary SS and 13 from other diseases. With RT-PCR, the IP-10 and beta-actin were co-amplified with specific primers. The gel-fractioned and ethidium bromide amplification products were then analyzed by densitometry. The expression of IP-10 was semi-quantificated by IP-10/beta-actin ratio. Twenty-one samples were examined by immunohistochemistry with specific goat anti-IP-10 antibody, 10 of them from primary SS, 3 from secondary SS, 8 from other diseases. 11 out of 21 samples were examined by both RT-PCR and immunohistochemistry.</p><p><b>RESULTS</b>The expression of IP-10 mRNA was significantly up-regulated in labial glands of patients with SS compared with other diseases (IP-10/beta-actin ratio was 0.329 +/- 0.157 vs 0.099 +/- 0.059, P < 0.01). The number of lymphocyte infiltration foci in labial glands of patients with SS correlated to the IP-10/beta-actin ratio (r = 0.657, P < 0.05). Ductal epithelial cells and some of the infiltrating lymphocytes were stained by anti-IP-10 antibody by immunohistochemistry in 8 of the primary SS (8/10), all of the secondary SS (3/3) and one with primary biliary sclerosis (1/8). The expression of IP-10 protein detected by immunohistochemistry was consistent with that of mRNA detected by RT-PCR.</p><p><b>CONCLUSIONS</b>IP-10 is abnormally highly expressed in the labial glands of patients with SS and positively relates to the lymphocyte infiltration. It thus suggests chemokine IP-10 may be one of the important molecules attracting the lymphocytes to the minor salivary glands to form the lymphocytic foci of Sjogren's Syndrome.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the diagnosis and therapy of systemic lupus erythematosus (SLE) patients with pulmonary thromboembolism (PTE).</p><p><b>METHODS</b>11 hospitalized cases were reviewed retrospectively in PUMC Hospital during January 1984-July 2001.</p><p><b>RESULTS</b>All 11 cases were suffered from severe active lupus with PTE. The SLE-DAI (SLE-disease active index) was 21.9 +/- 4.9. 7 cases had first onset of progressive Raynaud phenomenon. Anti-RNP antibody was positive in 73% of the cases. Echocardiogram revealed medium-severe pulmonary hypertension. When PTE was found, while 6 cases had started with smaller to medium dose of prednisone treatment, which was 20-30 mg/d, and other 4 cases received no prednisone. Only 1 received large dose of prednisone and immunosuppressor. Large dosage of prednisone, immunosuppressor with or without anticoagulant were given to those 6 and 4 patients after final diagnosis, respectively. 6 of 7 cases showed relieved Raynaud phenomenon while 4 cases hemoptysis were disappeared, echocardiogram had confirmed that pulmonary artery pressure decreased in 4 cases. [(31.7 +/- 12.4) mmHg]. 5 cases survived, 3 were dead and 3 failed to be followed up.</p><p><b>CONCLUSIONS</b>Patients of SLE with PTE are liable to be misdiagnosed or missed-diagnosed, The risk factors are active-SLE, progressive Raynaud phenomenon, and symptoms of thromboembolism, positive anti-RNP antibody and mild-medium pulmonary artery hypertension. Combined therapy of present available measures like large dose of prednisone, immunosuppressors and anticoagulant are highly recommended.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the clinical course and duration of therapy in 28 patients with polymyalgia rheumatica (PMR) and/or temporal arteritis (TA) for identifying factors that influence prolonged steroid use and relapses.</p><p><b>METHODS</b>28 cases of PMR and/or TA diagnosed from 1992 to 2001 were retrospectively studied in PUMC hospital. Patients were grouped according to the absence or presence of corticosteroid resistant and relapses.</p><p><b>RESULTS</b>Of 28 patients, 22 had pure PMR, 3 had both PMR and TA and 3 had pure TA. 15 patients received corticosteroid therapy and 13 had both corticosteroid and immunosuppressor therapy. The median duration was (25.5 +/- 24.0) months. Increase of white blood cell level and higher baseline erythrocyte sedimentation rate (ESR) were significant risk factors associated with corticosteroid resistant (P < 0.01). Quicker reduction of corticosteroid dose was associated with relapse (P < 0.05).</p><p><b>CONCLUSIONS</b>Patients with increase of white blood cell level and higher baseline erythrocyte sedimentation rate (ESR) are more likely to be resistant to corticosteroid therapy. Quicker reduction in corticosteroid is more likely to relapse. Immunosuppressor therapy should be added to patients who has corticosteroid resistant, and relapse or PMR associated with TA.</p>
