Evaluation of changes in oral health-related quality of life over time in patients with Sjögren's syndrome.

OBJECTIVES: To assess oral health-related quality of life (OHRQoL) and changes in OHRQoL in 3 years of patients with Sjögren's symdrome (SS). METHODS: Thirty-five SS patients and 23 non-SS individuals were enrolled. OHRQoL were quantitatively evaluated using the shortened Oral Health Impact Profile (OHIP-14). After 3 years, 22 patients and 14 controls tool the OHIP-14 survey again. RESULTS: The SS group had a significantly higher OHIP-14 score, which indicated a lower OHRQoL, than the non-SS group. Among individual questions in the OHIP-14, scores for 'trouble pronouncing words', 'uncomfortable to eat foods', 'self-conscious', and 'diet unsatisfactory' were markedly higher in the SS group than in the non-SS group. The OHIP-14 score significantly increased in 3 years in the SS group. Furthermore, there was an inverse correlation between the change rate of salivary flow rate and change of OHIP-14 scores in 3 years in patients with SS whose OHIP-14 score increased. Scores for 'irritable with other people', 'difficulty doing usual jobs', 'felt life less satisfying', and 'unable to function' significantly increased in 3 years. CONCLUSION: In SS, OHRQoL decreased in 3 years, which was associated with a decrease in saliva secretion. Moreover, troubles related to psychosocial aspects in SS patients were found to intensify over time.

Relationship between YKL-40 and pulmonary arterial hypertension in systemic sclerosis.

OBJECTIVES: Systemic sclerosis (SSc) is an intractable connective tissue disease that causes skin and organ fibrosis. Interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH) affect its prognosis. YKL-40 protein impacts inflammation and tissue remodeling. Therefore, we evaluated the utility of YKL-40 blood levels in identifying patients with SSc complicated by PAH, as confirmed by immunohistochemistry (IHC) examination. METHODS: We retrospectively analyzed 78 patients with SSc and performed IHC on 7 normal and 7 SSc skin samples in the Japanese population. Age-adjusted YKL-40 serum levels were analyzed. RESULTS: YKL-40 age percentile was significantly elevated in SSc patients. There was no difference between patients with SSc with and without ILD and PAH. YKL-40 age percentile was greater in patients with PAH complication. YKL-40 immunostaining was negative in normal skin and prominent in the subcutaneous vascular wall of all SSc samples. Receiver operating characteristic (ROC) curve analysis indicated that YKL-40 age percentile correctly differentiated between patients with and without PAH with a sensitivity of 80% and a specificity of 94.1%. CONCLUSION: A higher YKL-40 level with PAH may be reflective of angiogenesis due to capillary injury in SSc. YKL-40 may offer a useful and easily applicable diagnostic biomarker of SSc complicated with PAH.

Serum neopterin as well as ferritin, soluble interleukin-2 receptor, KL-6 and anti-MDA5 antibody titer provide markers of the response to therapy in patients with interstitial lung disease complicating anti-MDA5 antibody-positive dermatomyositis.

Objective: This study identified biomarkers that can be used to assess disease activity and response to therapy in patients with interstitial lung disease complicating anti-melanoma differentiation-associated gene 5 (MDA5) antibody (Ab)-positive clinically amyopathic dermatomyositis (CADM). Methods: In 15 patients with interstitial lung disease complicating anti-MDA5 Ab-positive CADM, anti-MDA5 Ab, neopterin, interleukin (IL)-18, ferritin, and soluble interleukin 2 receptor (sIL-2R) levels were measured in cryopreserved serum specimens before and at multiple times after remission induction therapy, and their correlations were assessed. Results: Anti-MDA5 Ab, neopterin, IL-18, ferritin, and sIL-2R levels did not differ significantly between patients who survived and those who succumbed to the disease. In many cases, serum anti-MDA5 Ab titers were over the upper limit (over 150 index value) before treatment in the usual measuring method, and gradually decreased to the normal range at stable phase. Meanwhile, serum neopterin levels (21.6 [15.3-48.3] nmol/L) were significantly elevated in newly diagnosed patients and fell to 6.8 (5-11.4) nmol/L at 6 months after treatment introduction. Conclusions: Elevated serum neopterin as well as ferritin, sIL-2R, KL-6, and anti-MDA5 Ab titer might help identify patients with interstitial lung disease complicated with DM and might be useful in monitoring response to therapy.

Rapid decrease in salivary epidermal growth factor levels in patients with Sjögren's syndrome: A 3-year follow-up study.

OBJECTIVES: To assess changes in salivary epidermal growth factor (EGF) levels within three years and investigate the correlation between these changes and the severity of intraoral manifestations in patients with Sjögren's syndrome (SS). METHODS: Twenty-three SS patients (14 primary SS and 9 secondary SS) and 14 controls were followed up for three years. Salivary EGF concentration was measured using an enzyme-linked immunosorbent assay, and intraoral manifestations were evaluated using a short version of the Oral Health Impact Profile (OHIP-14). Changes in salivary flow rate, EGF level, and severity of intraoral manifestations were analyzed, along with associations among them. RESULTS: The OHIP-14 score significantly increased and the total salivary EGF output significantly decreased after three years in the SS group (10.2 ± 8.8 vs. 12.6 ± 9.2, p = 0.040; 10158.4 ± 9820.9 vs. 8352.8 ± 7813.3 pg/10 min, p = 0.032), though the salivary flow rate did not change. The decrease in total EGF output was especially high in patients with long disease duration and poor oral health-related quality of life (OHRQoL). In patients with poor OHRQoL, the change in total EGF output significantly correlated with the OHIP-14 score (r = - 0.847, p = 0.008). However, there was no correlation between the change in salivary flow rate and the OHIP-14 score. CONCLUSIONS: The rapid decrease in salivary EGF level contributes to the progression of intraoral manifestations of SS.

Correlation between salivary epidermal growth factor levels and refractory intraoral manifestations in patients with Sjögren's syndrome.

OBJECTIVE: To assess changes in salivary epidermal growth factor (EGF) levels and the correlation between these levels and the severity of intraoral manifestations in Sjögren's syndrome (SS). METHODS: Forty SS patients and 23 controls were enrolled. Salivary EGF concentration was measured using an enzyme-linked immunosorbent assay, and intraoral manifestations were evaluated using a short version of the Oral Health Impact Profile (OHIP-14). The associations among salivary flow rate, EGF levels and the severity of intraoral manifestations were analyzed. RESULTS: The total salivary EGF output was significantly decreased in the SS patients compared with the controls (9237.6 ± 8447.0 vs. 13296.9 ± 7907.1 pg/10 min, respectively, p = 0.033). In the SS patients, total EGF output and salivary flow rate showed a strong positive correlation (rs = 0.824, p = 0.0005), while total EGF output and disease duration showed a negative correlation (rs = -0.484, p = 0.008). Further, total EGF output was significantly correlated with the OHIP-14 score (rs = -0.721, p = 0.012). CONCLUSIONS: The salivary flow rate and EGF levels are decreased in SS, and this deterioration in saliva quality causes refractory intraoral manifestations. Our findings have provided new therapeutic targets for SS.

Sphingosine 1-phosphate (S1P)/S1P receptor 1 signaling regulates receptor activator of NF-κB ligand (RANKL) expression in rheumatoid arthritis.

Sphingosine 1-phosphate (S1P)/S1P receptor 1 (S1P1) signaling plays an important role in synovial cell proliferation and inflammatory gene expression by rheumatoid arthritis (RA) synoviocytes. The purpose of this study is to clarify the role of S1P/S1P1 signaling in the expression of receptor activator of NF-κB ligand (RANKL) in RA synoviocytes and CD4(+) T cells. We demonstrated MH7A cells, a human RA synovial cell line, and CD4(+) T cells expressed S1P1 and RANKL. Surprisingly, S1P increased RANKL expression in MH7A cells and CD4(+) T cells in a dose-dependent manner. Moreover, S1P enhanced RANKL expression induced by stimulation with TNF-α in MH7A cells and CD4(+) T cells. These effects of S1P in MH7A cells were inhibited by pretreatment with PTX, a specific Gi/Go inhibitor. These findings suggest that S1P/S1P1 signaling may play an important role in RANKL expression by MH7A cells and CD4(+) T cells. S1P/S1P1 signaling of RA synoviocytes is closely connected with synovial hyperplasia, inflammation, and RANKL-induced osteoclastogenesis in RA. Thus, regulation of S1P/S1P1 signaling may become a novel therapeutic target for RA.

Serum B cell activating factor (BAFF) as a biomarker for induction of remission with rituximab in ANCA-associated vasculitis.

We examined whether serum B cell activating factor (BAFF) is useful for predicting the remission of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) following rituximab treatment. We used the Birmingham Vasculitis Activity Score (BVAS) 2008 version 3 for the evaluation of 27 patients with AAV 6 months after rituximab treatment. Those with BVAS = 0 achieved remission, whereas those with BVAS score > 0 did not achieve remission. We considered changes in serum BAFF before rituximab treatment, 1 month after treatment, and 6 months after treatment. In the remission group, the serum BAFF increased consistently. In the non-achieved group, serum BAFF was within the normal range. In addition, there was no statistically significant difference between the two groups in terms of serum BAFF before and 1 month after rituximab treatment. However, the serum BAFF level at 6 months after rituximab treatment was significantly higher in the remission group than in the non-achieved group. If serum BAFF does not increase after 6 months of rituximab in AAV, it may be assumed that there are residual B cells and plasma cells in the tissues. Enhanced treatment targeting B cells, including re-administration of rituximab or the addition of other immunosuppressive drugs, should be considered.

Recurrent myocardial infarction associated with vasculo-Behçet's disease: a case report.

A 39-year-old Japanese man presented with chest oppression in February 2017. Electrocardiogram showed ST-elevation myocardial infarction (MI), and cardiac catheterisation revealed thrombotic occlusion of the right coronary artery (RCA), which was treated with thrombectomy, and he received warfarin. Three days after discharge, he complained of chest oppression again, and re-cardiac catheterisation showed thrombi occlusion of the circumflex artery (LCX) and 90% stenosis with thrombosis in the proximal site of the anterior descending artery (LAD) and RCA. Drug eluting stent was implanted in the LAD and RCA; aspirin and prasugrel hydrochloride were added to warfarin. Before discharge, coronary computed tomography angiography (CTA) found new thrombi in the RCA, LAD, and LCX, and he was referred to our hospital on suspicion of Behçet's disease (BD). Past medical history was notable for recurrent aphthous stomatitis, a pudendal ulcer, and Crohn's disease, for which he had been taking infliximab (5 mg/kg) every 8 weeks until December 2016. Notably, his C-reactive protein (CRP) level increased before and after each MI, suggesting that the thrombi were caused by inflammation. Consequently, we concluded that his abnormalities were manifestations of vasculo-BD. After 3 days of hospitalisation, treatment with prednisolone and colchicine was started. His CRP and D-dimer levels decreased, and coronary CTA after 8 days showed disappearance of the thrombi. We tapered the prednisolone dose, and cardiovascular events have not been observed for 7 months after the treatment initiation. In summary, we report a rare case of MI associated with vasculo-BD and review the relevant literature.

Imatinib mesylate inhibited rat adjuvant arthritis and PDGF-dependent growth of synovial fibroblast via interference with the Akt signaling pathway.

Overgrowth of the synovium plays an important role in the pathogenesis of rheumatoid arthritis (RA). Platelet-derived growth factor (PDGF) is one of the most potent mitogenic factors of synovial cells, and imatinib mesylate (imatinib) is a specific inhibitor of the PDGF receptor tyrosine kinase. The aim of this study was to elucidate the anti-rheumatic activity of imatinib. The in vivo effects of imatinib were assessed by evaluating the sequential manifestation of adjuvant-induced arthritis in rats using paw volume and clinical scores. Imatinib was found to inhibit rat adjuvant-induced arthritis, but the inhibitory effects were incomplete. To confirm the mechanism of anti-rheumatic-activity of imatinib, we assessed the in vitro effects of imatinib on the proliferation of RA synovial fibroblast-like cells (RASFs) using a MTT assay. Intracellular signaling of PDGF was evaluated by Western blot analysis. Platelet-derived growth factor was found to induce a significant proliferation of RASFs, while imatinib inhibited PDGF-induced proliferation of RASF. Imatinib also inhibited PDGF-induced phosphorylation of the PDGF receptor and Akt, whereas constitutive activated extracellular signal-regulated kinase was not inhibited by imatinib. In contrast, imatinib did not inhibit transforming growth factor beta- and basic fibroblast growth factor-induced proliferation of RASF. Oral administration of imatinib ameliorated adjuvant-induced arthritis in rats, and it inhibited PDGF-induced RASF proliferation through disruption of the PDGF-R to Akt kinase signaling pathway. Because imatinib cannot inhibit the non-PDGF-dependent proliferation of RASFs, the anti-rheumatic effect of imatinib may be incomplete. The development of inhibitors of RASF proliferation may lead to the successful treatment of RA.

Assessment of 2012 EULAR/ACR new classification criteria for polymyalgia rheumatica in Japanese patients diagnosed using Bird's criteria.

AIM: The 2012 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for polymyalgia rheumatica (PMR) were published in 2012. The present study aimed to assess the 2012 EULAR/ACR classification criteria for PMR in Japanese patients diagnosed with PMR using Bird's criteria. METHODS: The study included 75 patients diagnosed using Bird's criteria. The patients were divided into fulfilled and not-fulfilled groups according to whether they met the 2012 EULAR/ACR classification criteria for PMR. The factors in the new criteria were morning stiffness duration > 45 min, hip pain or limited range of motion, absence of rheumatoid factor or anti-citrullinated protein antibody, and absence of other joint involvement. RESULTS: Thirty-two of the patients diagnosed with PMR using Bird's criteria met the new EULAR/ACR classification criteria, while the remaining 43 patients did not meet the new criteria. Among the factors, only morning stiffness duration > 45 min was an independent predictive factor. CONCLUSIONS: A morning stiffness duration > 45 min is the only independent predictive factor for differentiating patients diagnosed according to the new 2012 EULAR/ACR classification criteria for PMR.

A retrospective analysis of 7 cases of familial mediterranean fever.

BACKGROUND: Familial mediterranean fever (FMF) is a single inherited autoinflammatory disease characterized by periodic fever with relatively short duration of 1 to 3 days and sterile serositis. Although the prevalence rate is highest in the Mediterranean coastal area, a large number of cases have been reported recently by genetic analysis by identification of MEFV (Mediterranean fever) which is responsible gene in Japan too. In outpatient department of rheumatology, diagnosis and treatment of FMF is performed in cases where fever and abdominal pain attack are repeated for a short period of time. PATIENTS AND METHODS: We examined cases in which symptoms considered periodic seizures were repeated, excluding autoimmune diseases, infectious diseases, and malignant tumors. In both cases, genetic analysis is performed as auxiliary diagnosis. RESULTS: Seven cases satisfied the Tel-Hashomer criteria criteria and MEFV gene mutation was detected. Everyone was a female, and half had seizure symptoms at menstruation. Even though there is a difference in the amount of colchicine to be used, either one is effective. CONCLUSION: In cases of periodic symptoms or cases called periodic fever, exclusion diagnosis is carried out, there is a need to suspect FMF, determine the effect of colchicine, and perform genetic analysis.

[A case of anti-PL-7 antibody positive polymyositis with thrombotic microangiopathy].

  A 65-year-old woman with a 17-year history of polymyositis and 8-year history of rheumatoid arthritis who was treated with a low dose of prednisolone and tacrolimus (Tac) was admitted to our hospital because of general malaise and hypertension. Blood tests showed thrombocytopenia, hemolytic anemia with fragmented erythrocytes, and hypercreatinemia. Based on these clinical features, she was diagnosed with thrombotic micro-angiopathy (TMA). Thrombocytopenia and hemolytic anemia with fragmented erythrocytes improved with the discontinuation of Tac and plasma exchange; however, hypertension and renal dysfunction persisted. TMA due to calcineurin inhibitor (CNI) nephropathy was suspected based on the histopathological findings of renal biopsy. However, the condition was atypical of a CNI nephropathy because the trough level of Tac was lower than that reported previously and renal dysfunction persisted after drug discontinuation. She had mild sclerodactylia and Raynaud's symptoms, although the diagnostic criteria for systemic sclerosis (SSc) were not satisfied. Moreover, the patient tested positive for anti PL-7 antibody. The relationship between anti PL-7 antibody and pathogenesis of SSc has been reported. In this case, it was suspected that CNI nephropathy worsened because of the potential basic factors of SSc. These findings indicate that TMA may occur in patients testing positive for anti PL-7 antibody who are treated with Tac.

Salivary epidermal growth factor (EGF) in Sjögren's syndrome: association between salivary EGF levels and the severity of intraoral manifestations.

Sjögren's syndrome (SS) is a chronic inflammatory autoimmune disease characterized by lymphocytic infiltration of the exocrine glands, especially the salivary and lacrimal glands. As a result of salivary gland dysfunction, most patients with SS have xerostomia, related to a reduced salivary flow rate. In addition to the discomfort due to xerostomia, dry mouth can cause various intraoral manifestations such as refractory stomatitis, ulcer and atrophic changes in the oral mucosa and tongue, and patients' quality of life (QOL) is impaired severely. These manifestations are believed to be caused mainly by a decrease in the clearance in the oral cavity owing to hyposalivation. However, since saliva has several beneficial physiological effects on the intraoral environment, qualitative changes in sialochemistry should also be considered a cause of the refractory intraoral manifestations in SS. Salivary epidermal growth factor (EGF) is considered an important cytoprotective factor against injuries, and it contributes to wound healing in the oral cavity. We evaluated changes in salivary EGF levels and assessed the association between salivary EGF levels and the severity of intraoral manifestations in SS patients. The results showed that the salivary EGF levels decreased with the progression of SS, and this deterioration in saliva quality as well as hyposalivation could play a role in the pathogenesis of refractory intraoral manifestations in SS patients. Our findings provide new target for therapeutic intervention in SS.

A comparative proteomics study of a synovial cell line stimulated with TNF-α.

To elucidate the pathogenesis of rheumatoid arthritis (RA), we used proteomic analysis to determine the protein profile in a synovial cell line, MH7A, established from patients with RA. Proteins were extracted from MH7A cells that were or were not stimulated with tumor necrosis factor-α (TNF-α), and then analyzed on a liquid chromatography/mass spectrometry system equipped with a unique long monolithic silica capillary. On the basis of the results of this proteomic analysis, we identified 2650 proteins from untreated MH7A cells and 2688 proteins from MH7A cells stimulated with TNF-α. Next, we selected 269 differentially produced proteins that were detected only under TNF-α stimulation, and classified these proteins by performing gene ontology analysis by using DAVID as a functional annotation tool. In TNF-α-stimulated MH7A cells, we observed substantial production of plasminogen-activator inhibitor 2 and apoptosis-regulating proteins such as BH3-interacting domain death agonist, autophagy protein 5, apolipoprotein E, and caspase-3. These results indicate that the upregulation of plasminogen-activator inhibitor 2 and apoptosis-regulating proteins in synovial cells in response to TNF-α stimulation might represent a predominant factor that contributes to the pathogenesis of RA.

A case of familial Mediterranean fever who complained of periodic fever and abdominal pain diagnosed by MEFV gene analysis.

Familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease caused by Mediterranean FeVergene (MEFV) mutations on Chromosome 16, and characterized by periodic fever of and serositis. FMF is the result of gain-of-function mutations in pyrin that lead to interleukin-1ß activation. FMF can be classified as "typical" and "atypical" types based on clinical finding and genetic screening. Although MEFV genotyping has enabled FMF to be confirmed in some cases, the diagnosis remains predominantly clinical since genotyping has shown that the disease is characterized by variable manifestations in Japanese. In 1976, the first report performed on the case of Japanese FMF with periodic fever of and serositis. Since 2002, genetic analyses are performed on Japanese FMF patients by K. Shiozaki et al. and N. Tomiyama et al. In our case, she was a 25-year-old Japanese woman with at periodic fever and abdominal pain. MEFV gene analysis demonstrated a heterozygous mutation of variant M694I, leading to a diagnosis of FMF. After the increase dose (up to 3 mg/day) of colchicine, periodic fever and abdominal pain disappeared. It is the important candidate of FMF for differential diagnosis with unexplained periodic fever and serositis, such as our case.

Reliability and clinical utility of Enzyme-linked immunosorbent assay for detection of anti-aminoacyl-tRNA synthetase antibody.

Anti-aminoacyl-tRNA synthetase (ARS) antibody is one of the myositis-specific autoantibodies to make a diagnosis of polymyositis (PM) and dermatomyositis (DM). Recently a new enzyme-linked immunosorbent assay (ELISA) kit of concurrently detected anti-ARS antibodies (anti-Jo-1, anti-PL-7, anti-PL-12, anti-EJ and anti-KS) have become to measure in the clinical setting. To evaluate the reliability of this ELISA kit, we measured anti-ARS antibodies in 75 PM and DM patients using by this ELISA assay and compared them with the results by RNA immunoprecipitation assay. Between the measurements of anti-PL-7, anti-PL-12, anti-EJ and anti-KS autoantibodies by ELISA assay and RNA-IP assay, the concordance rate of reproducibility is 95.1% and the positive agreement rate is 90.9% and negative agreement rate is 96.0% and kappa statistic is 0.841. Between the measurements of existing anti-Jo-1 antibody ELISA kit and anti-ARS antibody ELISA kit, the concordance rate of reproducibility is 96.9%, the positive agreement rate is 100%, negative agreement rate is 96.1% and kappa statistic is 0.909. The lung involvement in patients with PM and DM patients are positive of anti-ARS antibodies and anti-melanoma differentiation associated gene5 (MDA5) antibody at a rate around 70%. Then most life-threatening ILD with anti-MDA5 positive clinically amyopathic dermatomyositis patients could be highly guessed when anti-ARS antibodies are negative.

A case of anti-aminoacyl tRNA synthetase antibody syndrome complicated by hemophagocytic syndrome.

A 48-year-old woman had suffered from a fever and general fatigue, and visited the other hospital for fever elevation in November 2013, at which time interstitial lung disease was revealed. In January 2014, she experienced an eruption in the hand and developed peripheral blood flow damage. Under a diagnosis of adult Still's disease, the patient was administered 0.5 mg of betamethasone as well as cyclosporin at 75 mg/day. In November 2014, general fatigue, fever, and headache were noted, while MRI revealed an enlarged hypophysis and laboratory findings were positive for the anti-pituitary cell antibody, thus a diagnosis of autoimmune hypophysitis was made. Although disease activity was low, she requested hospitalization and was admitted by the Division of Endocrinology and Metabolism at our hospital in May 2015, though only observed. Fever developed again, along with interstitial lung disease, Raynaud's phenomenon, and pain in the crural area again, and we considered the possibility of another disease. After stopping administration of betamethasone and cyclosporin, we made a diagnosis of anti-aminoacyl tRNA synthetase antibody syndrome, and administered methylprednisolone at 500 mg for 3 days as well as prednisolone at 35 mg/day following steroid pulse therapy. Although her condition soon improved, fever, muscle pain, and pancytopenia returned after 3 days. Bone marrow findings revealed the existence of hemophagocytosis, for which we again gave methylprednisolone at 500 mg for 3 days and cyclosporin at 125 mg/day. Thereafter, the patient recovered and was discharged from the hospital.

Marked efficacy of adalimumab for secondary gastrointestinal amyloidosis accompanied with ankylosing spondylitis.

A 39-year-old man with seronegative rheumatoid arthritis which was refractory to methotrexate and prednisolone therapy complained of epigastralgia, melena and diarrhea. Diffuse mucosal damage was observed on endoscopic examination, and histological findings of the gastric and colonal mucosa showed AA type amyloidosis. He was diagnosed with ankylosing spondylitis (AS) on the basis of the clinical feature such as the limitation in range of motion of lumber spine, and sacroiliitis on MR imaging. Although digestive symptom ameliorated by fasting and antibiotic therapy, laboratory findings continued to reveal an elevation of serum C-reactive protein (CRP) value and arthritis worsened. However, after the initiation of the treatment with adalimumab (ADA), not only his manifestation but also serum levels of CRP became normalized promptly. As far as we could evaluated, follow-up colonoscopic examination showed normal mucosal findings and histologic examination proved that amyloid protein disappeared. Secondary gastrointestinal amyloidosis is ralely associated with AS. Therefore standard therapy is not established. This case might indicate an efficacy of ADA for secondary gastrointestinal amyloidosis accompanied with AS.

[A case of HELLP syndrome at 34w-pregnancy with systemic lupus erythematosus and antiphospholipid antibody syndrome;Importance of measurement of VW factor].

SUMMARY: A 39-year-old woman was diagnosed with Systemic lupus erthymatosus (SLE) in 1993, and initially received 30 mg of prednisolone (PSL) daily as treatment. In 2012, the patient was diagnosed with pregnancy-induced hypertension (PIH) complecated with proteinurea, hypertension and pretibial edema at 24 weeks of gestation. At onset, protein urea was 1.6 g/day and she was given bed rest in the hospital with a protein-restricted and low salt diet, which led to a decrease in protein urea to approximately 1 g/day. At 34 weeks of gestation epigastric pain developed, and laboratory examinations showed liver dysfunction and low platelets. We made a diagnosis of hemolysis, elevated liver enzymes, low platelet (HELLP) syndrome and performed an emergency cesarean procedure. Thereafter blood pressure was elevated, protein urea was 3.2 g/daily, anti-ds-DNA antibody level was elevated and serum C3/C4/CH50 was reduced, thus we gave. plasma exchange therapy, along with immunoadsorption and steroid pulse therapy (methyl-prednisolone 500 mg/daily for 3 days), as well as PSL at 30 mg/day. Overtime clinical symptoms and laboratory data gradually improved. CONCLUSION: Some reports suggest that SLE during pregnancy is a risk factor for hypertension, nephritis, SLE relapse and HELLP syndrome. In the patient, ADAMTS13 activity did not decrease, while there was an increase in VW factor level. We assessed this case was as atypical thrombotic microangiopathy. And herein report HELLP syndrome during pregnancy associated with SLE in our patient.
