Clinical Effect of Runzaoling Combined with Iguratimod on Primary Sjögren's Syndrome / 中国实验方剂学杂志

ObjectiveTo investigate the clinical efficacy and safety of iguratimod combined with the Chinese medicine Runzaoling in the treatment of primary Sjögren's syndrome （pSS）. MethodSeventy-two patients treated in the Department of Rheumatology and Immunology of the Second Affiliated Hospital of Guizhou University of Traditional Chinese Medicine（TCM） from January 2021 to June 2022 who met the Western medical diagnosis of pSS and had the TCM syndrome of Yin deficiency and heat toxin syndrome were randomly assigned into an observation group and a control group， with 36 patients in each group. The observation group was treated with iguratimod combined with Runzaoling， and the control group was treated with iguratimod. The treatment in both groups lasted for 12 weeks. The clinical symptoms， EULAR Sjogren's syndrome patient reported index （ESSPRI）， EULAR Sjögren's syndrome disease activity index （ESSDAI）， erythrocyte sedimentation Rate （ESR）， C-reactive protein （CRP）， immunoglobulin （IgG）， Schirmer score， and saliva flow of the two groups were determined before and after treatment. Furthermore， the incidence of adverse reactions was compared between the two groups. ResultThe total response rate in the observation group was 75.0% （27 patients with response and 9 patients with no response）， which was higher than that （61.11%， 22 patients with response and 14 patients without response） in the control group （P<0.05）. After treatment， the ESSPRI， ESSDAI， and TCM syndrome scores in both groups decreased and the decreases were more obvious in the observation group than in the control group （P<0.05）. The treatment in both groups recovered the ESR， CRP， IgG， Schirmer score， and saliva flow （P<0.05）. Moreover， the observation outperformed the control group in terms of the ESR， CRP， IgG， and saliva flow （P<0.05） and had no significant difference in the Schirmer score compared with the control group. During the treatment period， 2 patients in the observation group had nausea， and 1 patient had an abnormal liver function， which were relieved after symptomatic treatment and did not affect the treatment. In the control group， 1 patient withdrew from the study due to rashes and showed no special discomfort in the follow-up 4 weeks， and 1 patient had nausea， which was relieved after symptomatic treatment. ConclusionIguratimod combined with Runzaoling has good clinical efficacy and safety in the treatment of pSS.

Encefalitis autoinmune seronegativa asociada a síndrome de Sjögren primario / Autoimmune seronegative encephalitis associated to primary Sjögren's disease

La encefalitis autoinmune es un trastorno inmunomediado que compromete distintos territorios del parénquima cerebral, involucrando frecuentemente la materia gris profunda o la corteza, con o sin compromiso de la materia blanca, meninges o médula espinal. Se asocia frecuentemente con enfermedades autoinmunes o paraneoplásicas, y constituye un reto diagnóstico. Reportamos el caso de una mujer de 55 años con antecedente de síndrome de Sjögren que consultó a Emergencias por cefalea y confusión. El líquido cefalorraquídeo (LCR) presentaba leucocitosis con neutrofilia. En la resonancia magnética nuclear (RMN) cerebral se evidenciaron múltiples imágenes de comportamiento restrictivo, de señal hiperintensa en T2 y FLAIR, a predominio córtico-subcortical a nivel occipital bilateral, hemisferio cerebeloso derecho y parietal derecho. Se descartaron infecciones y neoplasias. El panel de anticuerpos para encefalitis autoinmune aquaporina-4 y anti-MOG en LCR fue negativo. Recibió metilprednisolona endovenosa con mejoría progresiva de los síntomas.

Autoimmune encephalitis is an immune-mediated disorder that affects different areas of the brain parenchyma, often involving deep gray matter or the cortex, with or without involvement of white matter, meninges, or spinal cord. It is frequently associated with autoimmune or paraneoplastic diseases and is a diagnostic challenge. We report the case of a 55-year-old woman with history of Sjögren's syndrome who presented to the emergency department with headache and episodes of confusion. Cerebrospinal fluid (CSF) analysis showed leukocytosis with neutrophilia. Brain MRI revealed multiple restricted diffusion lesions with hyperintense signal on T2 and FLAIR sequences, predominantly in the bilateral occipital region, right cerebellar hemisphere, and right parietal region. Infections and neoplasms were ruled out. The panel of antibodies for autoimmune encephalitis, including Aquaporin-4 and anti-MOG in CSF, was negative. She received intravenous methylprednisolone, leading to symptom improvement.

Clinical and immunological features of primary Sjögren's syndrome patients with positive anti-centromere protein B antibody / 北京大学学报(医学版)

OBJECTIVE@#To investigate the clinical and immunological features of primary Sjögren's syndrome (pSS) patients with positive anti-centromere protein B (CENP-B) antibody.@*METHODS@#In this cross-sectional study, the general clinical data, radiographic examination and labial salivary gland biopsy data, and serum immunological and biochemical data of patients diagnosed with pSS from January 2016 to August 2022 were evaluated. The included patients were divided into the anti-CENP-B antibody positive and negative groups. Intergroup differences were analyzed with SPSS 23.0 software. Subgroup analysis was further performed by dividing the anti-CENP-B antibody positive group into the single anti-CENP-B antibody positive and with other auto-antibodies positive groups to determine the characters related to anti-CENP-B antibody.@*RESULTS@#In this study, 288 patients with pSS were evaluated, including 75 patients with anti-CENP-B antibody positive and 213 with anti-CENP-B antibody negative. Univariate analysis showed that compared with the anti-CENP-B antibody negative group, the patients of the anti-CENP-B antibody positive group were older, had lower proportion of the patients with salivary gland enlargement and higher proportion of autoimmune liver disease. As for immunological indicators, the positive proportions of anti-SSA/Ro60, anti-Ro52, and anti-SSB antibodies were significantly lower. Moreover, the immunoglobulin (Ig) G and rheumatoid factor levels were significantly lower, while the IgM level was significantly higher in the patients of the anti-CENP-B antibody positive group. As for serum biochemical indicators, for the patients of the anti-CENP-B antibody positive group, the level of total protein (TP) was lower, the albumin/globulin ratio was higher, and the levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH) were higher. Subgroup analysis showed that the levels of TP and IgA in the patients of the single anti-CENP-B antibody positive group were significantly lower than those of the patients with other autoantibodies positive group.@*CONCLUSION@#The pSS patients with anti-CENP-B antibody positive have unique clinical and immunological features of lower disease activity, less likely to involve salivary gland, higher risk for autoimmune liver disease, and higher levels of liver function indicators. Anti-CENP-B antibody may be a marker for a distinct subset of polyautoimmunity in Sjögren's syndrome.

Early prediction of severe COVID-19 in patients with Sjögren's syndrome / 北京大学学报(医学版)

OBJECTIVE@#To investigate the predictive value of blood cell ratios and inflammatory markers for adverse prognosis in patients with primary Sjögren's syndrome (PSS) combined with coronavirus disease 2019 (COVID-19).@*METHODS@#We retrospectively collected clinical data from 80 patients with PSS and COVID-19 who visited the Rheumatology and Immunology Department of the First Affiliated Hospital of Nanchang University from December 2022 to February 2023. Inclusion criteria were (1) meeting the American College of Rheumatology (ACR) classification criteria for Sjögren's syndrome; (2) confirmed diagnosis of COVID-19 by real-time reverse transcription polymerase chain reaction or antigen testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2); (3) availability of necessary clinical data; (4) age > 18 years. According to the clinical classification criteria of the "Diagnosis and Treatment Protocol for Novel Coronavirus Pneumonia (trial the 10th Revised Edition)", the patients were divided into the mild and severe groups. Disease activity in primary Sjögren' s syndrome was assessed using the European League Against Rheumatism (EULAR) Sjögren' s syndrome disease activity index (ESSDAI). Platelet-lymphocyte ratio (PLR), C-reactive protein-lymphocyte ratio (CLR), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and other laboratory data were compared between the two groups within 24-72 hours post-infection.@*RESULTS@#The mild group consisted of 66 cases with an average age of (51. 52±13. 16) years, and the severe group consisted of 14 cases with an average age of (52.64±10.20) years. Disease activity, CRP, platelets, PLR, and CLR were significantly higher in the severe group compared with the mild group (P < 0.05). Univariate analysis using age, disease activity, CRP, platelets, PLR, and CLR as independent variables indicated that disease activity, CRP, PLR, and CLR were correlated with the severity of COVID-19 (P < 0.05). Multivariate logistic regression analysis further confirmed that PLR (OR=1.016, P < 0.05) and CLR (OR=1.504, P < 0.05) were independent risk factors for the severity of COVID-19 in the critically ill patients. Receiver operator characteristic (ROC) curve analysis showed that the area under the curve (AUC) for PLR and CLR was 0.708 (95%CI: 0.588-0.828) and 0.725 (95%CI: 0.578-0.871), respectively. The sensitivity for PLR and CLR was 0.429 and 0.803, respectively, while the highest specificity was 0.714 and 0.758, respectively. The optimal cutoff values for PLR and CLR were 166.214 and 0.870, respectively.@*CONCLUSION@#PLR and CLR, particularly the latter, may serve as simple and effective indicators for predicting the prognosis of patients with PSS and COVID-19.

Comparison of clinical and immunological characteristics between primary Sjögren's syndrome patients with positive and negative anti-SSB antibody / 北京大学学报(医学版)

OBJECTIVE@#To analyze the differences of clinical manifestations and laboratory features between primary Sjögren's syndrome (pSS) patients with positive and negative anti-Sjögren's syndrome type B (SSB) antibody.@*METHODS@#The clinical data of pSS patients hospitalized in Department of Rheumato-logy and Immunology, Peking University Third Hospital were retrospectively analyzed to investigate the differences of clinical and laboratory features between anti-SSB positive and negative groups. The t test, Mann-Whitney U test, Chi-square test and Fisher's exact probability were used for analysis.@*RESULTS@#A total of 142 pSS patients were enrolled in this study, including 137 females and 5 males with a mean age of (54.8±13.3) years. The anti-SSB positive group included 44 patients accounting for 31.0% of the pSS patients. The anti-SSB positive pSS patients were younger at disease onset and at visit [age at visit: (50.9±14.5) years vs. (56.5±12.4) years; age at onset: (42.2±14.8) years vs. (49.5±15.3) years, P < 0.05]. The patients with anti-SSB positive more frequently presented with rash (29.5% vs. 14.3%, P < 0.05), enlargement of parotid glands (27.3% vs. 8.2%, P < 0.05), renal tubular acidosis (15.9% vs. 4.2%, P < 0.05), immune thrombocytopenia (9.1% vs. 1.0%, P < 0.05), rheumatoid factor (RF) positive (85.0% vs. 49.4%, P < 0.05), higher RF and antinuclear antibody (ANA) titers (median: 89.8 IU/mL vs. 20.5 IU/mL; median: 320 vs. 160, P < 0.05), anti-Sjögren's syndrome type A (SSA) antibody positive (97.7% vs. 64.3%, P < 0.05), elevation of γ globulin (71.4% vs. 38.5%, P < 0.05), higher levels of IgG (median: 21.0 g/L vs. 15.6 g/L, P < 0.05), higher proportions of CD3-CD19+ cells [(21.0±11.9)% vs. (13.7±9.6)%, P < 0.05] and lower proportions of CD3+ cells [(67.2±14.4)% vs. (76.6%±13.1)%, P < 0.05] than those negative. However, the anti-SSB positive group was less likely to show anti-mitochondrial antibodies (AMA)-M2 positivity (10.5% vs. 35.6%, P < 0.05). Glucocorticoids (90.9% vs. 73.5%, P < 0.05) and immunosuppressants (54.5% vs. 36.7%, P < 0.05) were more frequently used in anti-SSB positive pSS patients than those negative.@*CONCLUSION@#The anti-SSB positive pSS patients were younger at disease onset while more frequently presenting with various symptoms, higher levels of other antibodies and activation of B cells than those negative. Glucocorticoids and immunosuppressants were more frequently used, indicating that anti-SSB positive group presented with a more severe clinal phenotype.

Primary Sjögren syndrome and development of another autoimmune rheumatic disease during the follow-up

Abstract Background: Primary Sjögren syndrome (pSS) is a chronic autoimmune disease with its main target being exocrine glands, and is the connective tissue disease more frequently associated with other autoimmune diseases. The aim of this study was to assess the frequency of another autoimmune rheumatic disease (ARD) developed in primary Sjögren syndrome (pSS) patients and to describe it's clinical, serological and histologic characteristics. Materials and methods: This is a retrospective cohort study. Data of patients with pSS diagnosis (American-European criteria 2002), included in the GESSAR database (Grupo de Estudio Síndrome de Sjögren, Sociedad Argentina de Reumatología) were analyzed. The development of a second ARD was registered during the follow up. Results: 681 patients were included, 94.8% female. The mean age was 54 (SD 14) years and mean age at diagnosis of 50 (SD 13) years. The mean follow-up was 4.7 (SD 4.9) years; 30 patients (4.41%, CI 95%: 3.1-5.7) developed a second ARD during the follow up, incidence rate was 9.1/1000 patients-year (IR 95%: 5.8-12.4/1000 patients-year), the most frequent being rheumatoid arthritis (RA). 96% out of these 30 patients had xerophthalmia, 86.2% xerostomia, 92% positive Schirmer test, 88.24% positive Rosa Bengala test, lisamine green or Ocular Staining Score, 81.2% positive unstimulated salivary flow, 82.1% Ro(+) and 33.33% La(+). Minor salivary gland biopsy had been performed in 14 of the 30 patients, 12 with positive results. There were no statistically significant differences respect baseline characteristics when comparing the patients who developed another ARD to the ones that did not. Conclusions: Of all the patients analyzed, 4.4% presented another ARD during their follow-up. It is important to be aware of this, to make an early and proper diagnosis and treatment of our patients. Key points Patients with primary Sjögren's Syndrome may develop another connective tissue disease during follow-up. The most frequently connective tissue disease developed during follow-up in the population of patients with primary Sjogren's Syndrome studied was rheumatoid arthritis. It is important to be aware of this to make an early and proper diagnosis.

Conclusión: Nuestro estudio sugiere un menor compromiso glandular en pacientes con SSp diagnosticados a menor edad, sin un patrón diferencial característico en cuanto al compromiso sistémico.

Objective: To describe and compare the clinical manifestations, in adult patients diagnosed with primary Sjögren's Syndrome at age less than or equal to 35 years versus those over 35 years of age. Materials and Methods: We analyzed the data of patients older than 18 years, with diagnosis of primary Sjögren's syndrome (American - European criteria 2002), included in the GESSAR database (Sjögren Syndrome Study Group of the Argentine Society of Rheumatology). Results: 665 patients were included. One hundred of them with an age at diagnosis less than or equal to 35 years and with a mean age at diagnosis of 29 + 4 years, 92% of them women. The average age at diagnosis of the group over 35 years was 54 + 11 years, 96% women. Statistically significant differences were found between less than or equal to 35 years vs over 35 years, in xerophthalmia (90.72% vs 95.64%, p: 0.04) and xeroderma (42.35% vs 57.36% , p: 0.03), and in the following domains of ESSDAI (EULAR Activity Index for primary Sjögren's syndrome): peripheral nervous system (4.05 vs 11.32, p: 0.03), respiratory (6% vs 15.40%, p: 0.01) and renal (6% vs 1.59%, p: 0.02). Conclusion: Our study suggests less glandular involvement in patients with pSS diagnosed at a younger age, without a characteristic differential pattern regarding systemic involvement.

Traditional Chinese medicine is a useful and promising alternative strategy for treatment of Sjogren's syndrome: A review / 中西医结合学报

Primary Sjogren's syndrome (pSS) is a chronic autoimmune disease involving exocrine glands. Current studies have found that the occurrence of the disease is closely related to genetic, environmental and neuroendocrine factors, as well as abnormal activation of T and B lymphocytes. The etiology and pathogenesis of pSS is complex, and there is a lack of specific targeted drugs. Traditional Chinese medicines (TCMs) have been comprehensively investigated for their treatment effects on pSS. Through a systematic review of the literature, we summarized the TCMs used to treat pSS, and find that there are four major ways that TCMs are used, including upregulation of aquaporin proteins, suppression of cell apoptosis, suppression of the abnormal activation of B lymphocytes and suppression of the abnormal activation of T lymphocytes (balancing T helper type [Th]1/Th2 & Th17/Treg and suppressing follicular helper T [Tfh] cells). However, there are not enough data about the active constituents, quality control, pharmacokinetics, toxicity and modern preparations of these TCMs; therefore, more investigations are needed. This paper highlights the importance of TCMs for treating pSS and provides guidance for future investigations.

Questions as regards the recognition of elderly-onset primary Sjögren's syndrome: Where we are and where we would rather be / Preguntas sobre el reconocimiento del síndrome de Sjögren primario con inicio en la edad avanzada: ¿dónde estamos y dónde preferiríamos estar?

ABSTRACT Several epidemiological studies have suggested that the prevalence of the onset of primary Sjögren's Syndrome in the elderly (EOpSS) is significantly higher (between five to eight times) than in other age groups. However, when a literature review was performed, the number of patients with EOpSS was much lower than epidemiologically expected. An evaluation was performed on Sjögren (sicca) syndrome, including immunological markers, labial salivary glands biopsy, and some extra-glandular manifestations. These could be confounding factors in the elderly patients, much more so than in other age groups, and lead to a misdiagnosis of EOpSS. This article presents a review of the most common difficulties that may be present in the recognition of EOpSS, and highlights the lack of elderly patient-centred studies as the most important unmet need.

RESUMEN Varios estudios epidemiológicos han sugerido que la prevalencia del síndrome de Sjögren primario (SSp) en la población de edad avanzada (Elderly-Onset primary Sjögren's Syndrome [EOpSS], según la clasificación inglés) es considerablemente mayor (entre 5 y 8 veces) que en grupos de edad diferente. Sin embargo, una revisión sistemática de la literatura mostró que el número de pacientes con EOpSS era mucho menor de lo que se esperaba epidemiológicamente. La evaluación del síndrome de sicca, los marcadores inmunológicos, la biopsia de las glándulas salivales labiales y algunas manifestaciones extraglandulares podrían convertirse en factores de confusión en pacientes de edad avanzada mucho más frecuentemente que en personas de otros grupos de edad, lo que favorecería un diagnóstico erróneo del EOpSS. En este artículo se revisan las principales dificultades que pueden afectar al reconocimiento del EOpSS, destacando la falta de estudios centrados en el paciente anciano como la necesidad insatisfecha más importante.

Clinical Efficacy of Shashen Maidongtang Plus Total Glucosides of Paeony Capsule in Treatment of Primary Sjogren's Syndrome with Based on Theory of Fluid Metabolism / 中国实验方剂学杂志

Objective:To investigate the clinical efficacy of Shashen Maidongtang plus total glucosides of paeony capsule on primary Sjogren's syndrome (pSS) based on the theory of fluid metabolism. Method:In this study, 84 patients of Qi-Yin deficiency type pSS admitted in Zhengzhou Chinese Medicine Hospital from January 2018 to January 2019 were divided into observation group (42 cases) and control group (42 cases) on the basis of random number table. The control group was orally given total glucosides of paeony capsule and iguratimod tablet, while the observation group was orally given Shashen Maidongtang combined with glucosides of paeony capsule. After 3 months of continuous treatment to all subjects, the clinical efficacy was evaluated, and side effects were recorded. Before and after the treatment, the saliva flow rate and basal tear secretion Schirmer I test (SIt) value were measured, European League Against Rheumatism Sjogren's syndrome patient reported index and Sjogren's syndrome disease activity index (ESSPRI and ESSDAI) were scored, the erythrocyte sedimentation rate (ESR) was determined by Westergren, and the levels of serum rheumatoid factor (RF) and immunoglobulin (Ig) G were tested by immunoturbidimetry and rate scattering turbidimetry, respectively. Result:The overall effective rate of the observation group was 90.48% (38/42), which was much higher than 69.05% (29/42) of the control group (χ2=5.974，P<0.05). After treatment, the saliva flow rates and SIt values of both groups got significantly increased compared with those before the treatment (P<0.05), but the saliva flow and SIt of the observation group were significantly better than those of the control group over the same period after treatment (P<0.05). After treatment, both groups had a great decrease in ESSPRI and ESSDAI scores compared with those before the treatment (P<0.05), and the above scores of the observation group were dramatically lower than those of the control group over the same period (P<0.05). After treatment, ESR, serum RF, and IgG levels of both groups were significantly lower than those before the treatment (P<0.05), and the observation group showed higher levels of ESR, serum RF and IgG than the control group over the same period after treatment (P<0.05). Side effects were few and mild in both groups. Conclusion:In treating patients of Qi-Yin deficiency type pSS, Shashen Maidongtang plus total glucosides of paeony capsule was proven to be effective generally. It could significantly inhibit excessive inflammation and hyperhumoral immunity in patients, and control their disease activity. This may be related to the effect of Shashen Maidong decoction and its decomposed recipes in correcting body fluid infusion and metabolic disorder in patients of Qi-Yin deficiency type pSS.

Results The subject was diagnosed with pSS by autoantibody detection, lip biopsy, and ophthalmologic examination. The symptoms were improved after immunosuppressive therapy. According to the literature, the incidence of childhood pSS was low, in which the incidence with involvment of the nervous system as primanry manifestation was even lower, and headache is the most common symptom of central nervous system. The application of corticosteroids and immunosuppressants may help improve the conditions. Conclusions Involvement of central nervous system in childhood pSS is not typical. Detection of autoantibodies and lip biopsy are helpful for diagnosis.

A Case of Treatment with Steroid and Hydrochloroquine of Thrombocytopenia in Primary Sjögren's Syndrome / 고신대학교의과대학학술지

Sjögren's syndrome is a systemic autoimmune disease characterized by sicca symptoms and extraglandular manifestations. Anemia, leukopenia, thrombocytopenia and lymphoproliferative disorders are well-known extraglandular, hematological complications of Sjögren's syndrome. These hematologic alterations are usually mild and respond well with steroid therapy. We report a case of a 52-year-old female patient who was initially presented with thrombocytopenia. The patient was then diagnosed with primary Sjögren's syndrome and initially treated with steroid. The patient's platelet count was decreased when steroid was tapered. The dose of steroid could be effectively reduced after combined medication with hydroxychloroquine.

Correlations between Tear Osmolarity and Ocular and Systemic Parameters in Primary Sjögren's Syndrome

PURPOSE: To investigate the relationships between tear osmolarity and various parameters for ocular and systemic disease in primary Sjögren's syndrome. METHODS: The medical records of 53 patients with primary Sjögren's syndrome were reviewed. Tear osmolarity using a TearLab® (TearLab™ Corp., San Diego, CA, USA) osmometer as well as other dry eye parameters such as tear break-up time, ocular staining score (Sjögren's International Collaboration Clinical Alliance [SICCA] ocular staining score, SICCA score), Schirmer-I score, symptoms with Ocular Surface Disease Index (OSDI), and Visual Analog Scale (VAS) were obtained. Systemic laboratory data and medication history were also collected. The correlations between the parameters were analyzed using the Spearman's rank correlation test. RESULTS: 53 patients with a mean age of 54.1 ± 13.2 years and female predominance (96.23%) were enrolled. The majority of patients (28.3%) were receiving systemic therapy for severe Sjögren's syndrome. The tear osmolarity in Sjögren's syndrome patients was 307 ± 13.6 (mOsm/L). Higher tear osmolarity was associated with lower tear film break-up time (BUT) scores and with higher SICCA scores. Tear osmolarity and the Schirmer test results were not significantly related. Higher tear osmolarity was paradoxically associated with lower VAS scores and lower OSDI scores. Neither current medication nor the salivary gland focus score showed significant associations with tear osmolarity. Although tear osmolarity was not associated with the SSA-Ro or SSA-LA titer, serum immunoglobulin G (IgG) level and serum erythrocyte sedimentation rate (ESR) level showed positive correlations with tear osmolarity. CONCLUSIONS: Tear osmolarity is positively correlated with the severity of dry eye and was associated with lower symptom severity. The significant associations of tear osmolarity with IgG and ESR suggest that high tear osmolarity may be correlated with autoantibody load and the systemic inflammatory state.
