Ziwan-Taoren herb pair can exert an therapeutical effect in primary Sjogren’s syndrome through inhibiting the TLR/NF-κB pathway

Background:Ziwan and Taoren(ZT)is a classic medicine pair in the formula of Mai Dong Di Shao Decoction,has been used to treat primary Sjogren’s syndrome(pSS)for more than 20 years.But its action mechanism is still unknown.This study is aimed to reveal the potential mechanism of ZT treated pSS and discover its active compounds of ZT and therapeutic target for pSS.Methods:Firstly,the potential pathways of ZT for pSS treatment were predicted through network pharmacology and GO and KEGG enrichment analysis.Secondly,the inter-structural relationships between active compounds of ZT and target proteins were visualized using molecular docking techniques.Finally,efficacy and mechanism were conducted through in vivo experiments,such as water intake,spleen index,hematoxylin-eosin staining pathological changes,ELISA,Western Blot analysis,and immunofluorescence staining.Results:Nine active compounds were extracted from network pharmacology,including quercitrin,luteolin,kaempferol,β-sitosterol,isorhamnetin,galangin,hederagenin,diosmetin and gibberellin 7.Seven disease targets were identified:RELA,TP53,AKT1,interleukin(IL)6,MAPK1,ESR1,IL10;with RELA being the most core target.KEGG and GO enrichment analysis indicated that ZT may act through the TLR/NF-κB/RELA inflammatory mechanism process.preliminary results of molecular docking showed that ZT’s active compounds bind well to the RELA(p65)receptor.In vivo results demonstrated that a high dose of ZT significantly improved water intake and reduced lymphocytes infiltration in submandibular gland pathology in NOD mice.The expression content of AQP5 and vasoactive intestinal peptide in the submaxillary gland was significantly increased,while levels of inflammatory factors such as tumor necrosis factor-α,IL-6,and IL-1βalong with protein expressions including toll-like receptor4,p-p65 and p-IKKα/βin NF-κB pathway were reduced.Conclusions:The ZT treatment exhibits a promising efficacy in mitigating dryness symptoms of pSS,potentially attributed to its capacity for suppressing the TLR/NF-κB inflammatory signaling pathway.

Renal Vein Thrombosis Suggestive of Extramembranous Glomerulonephritis Associated with Sjögren’s Syndrome (Case Report)

Introduction: Glomerular damage during Gougerot-Sjgren syndrome is much rarer than interstitial damage, and is essentially extra-membranous and membrano-proliferative glomerulonephritis. Observation: We report the case of a 44-year-old woman with primary Sjgrens syndrome, confirmed by clinical dryness syndrome, positive anti-SSA and anti-SSB antibodies, and a salivary gland biopsy revealing grade 4 lymphocytic sialadenitis according to CHISHOLMs classification. Later, the patient developed nephrotic syndrome, along with hypertension. Renal function remained normal with a creatinine level of 9.3 mg/l, and hematuria was absent. Only antinuclear antibodies tested positive, while anti-PLA2R antibodies were negative. A renal biopsy was performed, which was complicated on the same day by hemodynamic instability with hematuria. Renal CT scan with contrast injection revealed a posterior perirenal hematoma without contrast extravasation. Additionally, bilateral renal vein thrombosis was incidentally discovered, suggesting extramembranous glomerulonephritis. The patients hemodynamic status stabilized after fluid resuscitation with isotonic saline solution (0.9%), without the need for blood transfusion. Renal biopsy confirmed extramembranous glomerulonephritis with interstitial fibrosis and minimal tubular atrophy. The initial etiological assessment was negative. The patient was started on oral corticosteroids, angiotensin-converting enzyme inhibitors, and therapeutic anticoagulation for renal vein thrombosis. The patients condition improved, with the disappearance of the syndrome and spontaneous regression of the hematoma. Discussion: The association of nephrotic syndrome and renal vein thrombosis primarily suggests glomerulopathy, in particular extra-membranous glomerulonephritis. Sjgrens syndrome can be associated with extra-membranous glomerulonephritis without being its direct cause. Like, it is possible that it is a cause of glomerulonephritis, essentially extra membranous and membrano-proliferative. Conclusion: Sjgrens syndrome is generally underestimated cause of glomerulonephritis, which should be considered in cases of extra-membranous glomerulonephritis.

EVALUATION OF INTERNATIONAL CLASSIFICATION CRITERIA (2002) FOR PRIMARY SJGREN'S SYNDROME IN CHINESE PATIENTS

Objective To evaluate the sensitivity and specificity of international classification criteria （2002） for primary Sjogren＇s syndrome （pSS） and the role of lower lip biopsy in diagnosis of pSS in Chinese patients. Mothoda Patients who were diagnosed by the experts/rheumatologists as pSS during 1990-2002 from the Department of Rheumatology, Peking Union Medical College Hospital were retrospectively collected as experimental group. Patients who were diagnosed as non-pSS connective tissue diseases or non-connective tissue diseases served as control group. Those with a history of head-neck radiation, hepatitis C virus infection, AIDS, lymphoma, sarcoidosis, graft versus host disease （GVHD）, and anti-acetylcholine drug use were exempted. Both groups were required to complete questionnaires about symptoms such as dry eyes and dry mouth, and complete the objective tests of keratoconjunctivitis and xerostomia including Schirmer test, corneal staining, unstimulated salivary flow, sialography, lower lip biopsy, and antinuclear antibodies （including anti-SSA/SSB antibodies） test. Results A total of 330 pSS patients were included in experimental group and 185 non-pSS patients in control group. The mean age of both groups matched （47.8 ± 10.9 years vs. 46.2±13.6 years, P 〉 0.05）. The sensitivities of the criteria in pSS patients with lower lip biopsy and in pSS patients without lower lip biopsy were 89.2% and 87.2%, respectively; the overall sensitivity was 88.5%. The specificity was 97.3%. A total of 11.3% pSS patients with negative anti-SSA/SSB antibodies were diagnosed as pSS by lower lip biopsy. Coadwion The international classification criteria （2002） for pSS is feasible in Chinese patients. It has high sensitivity and specificity, and may serve as diagnosis criteria in routine clinical practice.

Iguratimod in treatment of primary Sjögren’s syndrome concomitant with autoimmune hemolytic anemia:A case report

BACKGROUND Primary Sjögren's syndrome(pSS)concomitant with autoimmune hemolytic anemia(AIHA)but without eye and mouth dryness is exceedingly rare.Iguratimod(IGU)has been widely used in the treatment of pSS.However,there are few reports about the application of IGU in pSS concomitant with AIHA.CASE SUMMARY Here,we present the case of a patient with pSS concomitant with AIHA but without eye and mouth dryness.The patient was initially diagnosed with hyperplastic anemia and AIHA while pSS was missed,and was finally diagnosed with pSS concomitant with AIHA.The patient was treated with IGU along with prednisone and hydroxychloroquine,and her hemoglobin,reticulocytes and IgG returned to normal levels.CONCLUSION IGU was effective for and well tolerated by our patient with pSS concomitant with AIHA,and may be a promising therapy for the treatment of this disease.

Higher frequency of brain abnormalities in neuromyelitis optica spectrum disorder patients without primary Sjogren's syndrome

Neuromyelitis optica spectrum disorder often co-exists with primary Sjogreffs syndrome. We compared the clinical features of 16 neuro- myelitis optica spectrum disorder patients with （n = 6） or without primary Sjogreffs syndrome （n = 10）. All patients underwent extensive clinical, laboratory, and MRI evaluations. There were no statistical differences in demographics or first neurological involvement at onset between neuromyelitis optica spectrum disorder patients with and without primary Sjogren＇s syndrome. The laboratory findings of cerebrospinal fluid oligoclonal banding, serum C-reactive protein, antinudear autoantibody, anti-Sjogren＇s-syndrome-related antigen A an- tibodies, anti-Sjogren＇s-syndrome-related antigen B antibodies, and anti-Sm antibodies were significantly higher in patients with primary Sjogren＇s syndrome than those without. Anti-aquaporin 4 antibodies were detectable in 67% （4/6） of patients with primary Sjogren＇s syndrome and in 60% （6/10） of patients without primary Sj6gren＇s syndrome. More brain abnormalities were observed in patients without primary Sj6gren＇s syndrome than in those with primary Sj6gren＇s syndrome. Segments lesions （〉 3 centrum） were noted in 50% （5/10） of patients without primary Sj6gren＇s syndrome and in 67% （4/6） of patients with primary Sjogren＇s syndrome. These findings indicate that the clinical characteristics of neuromyelitis optica spectrum disorder patients with and without primary Sjogren＇s syndrome are similar. However, neu- romyelitis optica spectrum disorder patients without primary Sjogreffs syndrome have a high frequency of brain abnormalities.

Management of primary ciliary dyskinesia/Kartagener＇s syndrome in infertile male patients and current progress in defining the underlying genetic mechanism

Kartagener＇s syndrome （KS） is an autosomal recessive genetic disease accounting for approximately 50% of the cases of primary ciliary dyskinesia （PCD）. As it is accompanied by many complications, PCD/KS severely affects the patient＇s quality of life. Therapeutic approaches for PCD/KS aim to enhance prevention, facilitate rapid definitive diagnosis, avoid misdiagnosis, maintain active treatment, control infection and postpone the development of lesions. In male patients, sperm flagella may show impairment in or complete absence of the ability to swing, which ultimately results in male infertility. Assisted reproductive technology will certainly benefit such patients. For PCD/KS patients with completely immotile sperm, intracytoplasmic sperm injection may be very important and even indispensable. Considering the number of PCD/KS susceptibility genes and mutations that are being identified, more extensive genetic screening is indispensable in patients with these diseases. Moreover, further studies into the potential molecular mechanisms of these diseases are required. In this review, we summarize the available information on various aspects of this disease in order to delineate the therapeutic objectives more clearly, and clarify the efficacy of assisted reproductive technology as a means of treatment for patients with PCD/KS-associated infertility.

Role of ranulas in early diagnosis of Sjögren’s syndrome: A case report

BACKGROUND Although the presentations of Sjögren’s syndrome(SS)are variable,ranging from mild dryness to wider systemic involvement,ranulas as early clinical signs were scarcely reported.Here,we present an adult patient with SS,who developed a unilateral simple ranula and was diagnosed primary SS 3 years later.We also provide a review of cases of SS and ranulas from 1980 to 2020.CASE SUMMARY A 22-year-old girl was found to have a left painless floor-of-mouth lesion 3 years ago,without obvious trauma or inducement.The diagnosis of a unilateral(left)simple ranula was made,and the ranula was surgically treated.Within 3 years after the ranula surgery,she developed acute lymphadenectasis in unilateral parotid twice without inducement,and ultrasonic examination revealed diffuse lesions in bilateral parotids and submandibular glands,which strongly suggested SS.Serologic tests and the unstimulated whole saliva flow rate confirmed the SS diagnosis.CONCLUSION Our study underlines that ranulas are early clinical signs of SS.As early diagnosis and early intervention of SS are important to obtain better outcomes,our findings underline the need for histopathological test after sublingual adenectomy and imaging detection of exocrine glands for the patients with ranulas.

Primary aldosteronism due to bilateral micronodular hyperplasia and concomitant subclinical Cushing’s syndrome:A case report

BACKGROUND Adrenal incidentaloma(AI)has been frequently encountered in the clinical setting.It has been shown that primary aldosteronism(PA)or subclinical Cushing’s syndrome(SCS)are the representative causative diseases of AI.However,the coexistence of PA and SCS has been reportedly observed.Recently,we encountered a case of AI,in which PA and SCS coexisted,confirmed by histopathological examinations after a laparoscopic adrenalectomy.We believe that there were some clinical implications in the diagnosis of the present case.CASE SUMMARY A 58-year-old man presented with lower right abdominal pain with a blood pressure of 170/100 mmHg.A subsequent computed tomography scan revealed right ureterolithiasis,which was the cause of right abdominal pain,and right AI measuring 22 mm×25 mm.After the disappearance of right abdominal pain,subsequent endocrinological examinations were performed.Aldosterone-related evaluations,including adrenal venous sampling,revealed the presence of bilateral PA.In addition,several cortisol-related evaluations showed the presence of SCS on the right adrenal adenoma.A laparoscopic right adrenalectomy was then performed.The histopathological examination of the resected right adrenal revealed the presence of a cortisol-producing adenoma,while CYP11B2 immunoreactivity was absent in this adenoma.However,in the adjacent nonneoplastic adrenal,multiple CYP11B2-positive adrenocortical micronodules were detected,showing the presence of aldosterone-producing adrenocortical micronodules.CONCLUSION Careful clinical and pathological examination should be performed when a patient harboring AI presents with concomitant SCS and PA.

Peripheral Neuropathies Revealing Gougerot-Sjögren’s Syndrome: Description of 3 Cases

Introduction: Sjögren’s syndrome is an autoimmune epithelitis with various extraglandular signs, among which are neurological, with a variable frequency according to studies. We report three cases of peripheral neuropathy revealing Gougerot-Sjögren’s syndrome, collected in the Neurology Department of the Fann University Hospital in Dakar (Senegal). Observations: The first patient, aged 48 years, presented with a length-dependent sensitivomotor polyneuropathy associated with retrobulbar optic neuritis, with dry eyes and dry mouth noticed by the patient for several years. The second patient, aged 28 years, was admitted to the hospital with chronic generalized paresthesia in the context of xerostomia and xerophthalmia. The results of the clinical examination and the electroeneuromyogram were in favour of pure sensory neuronopathy. The third patient was 32 years old female, with a history of thyroidectomy and acute inflammatory demyelinating polyneuropathy (AIDP), who was seen for acute ascending flaccid tetraplegia with facial diplegia, preceded by diffuse paresthesia. The diagnosis of recurrence of acute demyelinating polyradiculonueropathy was retained in view of the rapidly increasing character of the deficit, the hyperproteinorachy at the lumbar puncture, and the signs of demyelination at the ENMG. The diagnosis of Gougerot-Sjögren’s syndrome in our three patients was established on the basis of the 2016 ACR/EULAR criteria. Indeed, the anti-SSA antibodies (Ro) were positive in our 3 patients with a biopsy of the salivary glands which showed stage 3 in the first patient and stage 4 in the two others. Corticosteroid therapy and immunosuppressive treatment resulted in a favourable clinical evolution on the neurological and general levels. Conclusion: Gougerot-Sjögren’s syndrome is an autoimmune exocrinopathy that may present with peripheral neuropathy, which may precede the diagnosis of Sjögren’s syndrome, be concomitant or occur during the course of the disease.

Sjögren’s Syndrome Revealed by Obstructive Renal Failure: A Case Report and Review of the Literature

Introduction: Primary Sjögren’s syndrome (SS) is the most common connective tissue disease after rheumatoid arthritis and affects mostly women between 30 and 40 years of age with an estimated prevalence between 0.1% and 0.6%. This observation illustrates an incidental finding of a case of SS in a young female patient in a context of obstructive renal failure (ARF) due to uterine fibroids. Observation: This was a 31-year-old woman hospitalized for anuric AKI (Acute Kidney Injury) with a creatinine level of 1247 μmol/l. Her history included sickle cell disease A/C and an unoperated uterine fibroid diagnosed 3 years ago. Approximately 2 months before her admission, her symptomatology was made of dizziness, physical asthenia, vomiting, poly-arthralgia, morning rash, pollakiuria and oral dryness. Abdominal examination showed a painless transverse mass in the pelvis. Biological examination showed a CRP (C-reactive protein) level of 488 mg/l. The cytobacteriological examination of the urine was normal and the proteinuria was 1.35 g/24 hours. The CT scan showed kidneys measuring 110 mm on the right and 113 mm on the left associated with bilateral pyelo-caliceal dilatation on a large polymyomatous uterus of interstitial and submucosal type. Immunologically, the anti-nuclear factor, the rheumatoid factor and the anti-SSA antibodies were positive. The resumption of the interrogation within the framework of the research of the subjective dry syndrome to find a notion of intermittent xerophthalmia 4 months ago. The Schirmer test was positive in the left eye. The initial management consisted of a polymyomectomy after 3 sessions of hemodialysis. Background treatment combining prednisone 5 mg/day and methotrexate 20 mg/week was started in parallel with the use of artificial tears. The evolution after twelve (12) months of treatment was favorable with a complete disappearance of the signs dry syndrome and full recovery of renal function. Conclusion: SS can have an insidious evolution and remain stable for many years, hence its fortuitous discovery in this case of obstructive ARF on uterine fibroid. In this context we insist on the interest of the immunological assessment in a patient in period of genital activity with a significant proteinuria and non-specific extrarenal signs.

Gastrointestinal microbiome and primary Sjogren’s syndrome: a review of the literature and conclusions

The recognition of the profound impact of the human gastrointestinal microbiome(GM) on human autoimmune diseases has gradually increased thanks to deeper research efforts. As a systemic autoimmune disease, primary Sjogren’s syndrome(pSS) cannot be completely cured. Human studies have revealed that GM species and diversity are altered in patients with p SS compared with healthy individuals. Animal studies have provided possible mechanisms for the association between pSS and GM. The potential role of GM in pSS is exerted through several mechanisms. GM dysbiosis leads to increased intestinal permeability, which increases the risk of GM antigen exposure and activates specific autoreactive T lymphocytes via “molecular mimicry”. In addition, GM antigen exposure and intestinal immune tolerance loss caused by GM dysbiosis together induce chronic local gut mucosal inflammation, which deteriorates to systemic chronic non-specific inflammation with the circulation of pro-inflammatory lymphocytes and cytokines. These factors eventually activate autoreactive B lymphocytes and lead to pSS. If GM plays a key role in the pathogenesis of pSS, clarifying the underlying mechanisms will be helpful for the development of new therapies targeting GM for dry eye associated with pSS. This review summarizes the latest knowledge about the relationship between GM and p SS,with the aim of contributing to future research and to the development of new clinical applications.

Primary thymic mucosa-associated lymphoid tissue lymphoma with multiple thin walled lung cysts: case report and literature review

Mucosa-associated lymphoid tissue （MALT） lymphoma of the thymus is rare. We reported a case of a 37-year-old Chinese female with Sjtgren＇s syndrome and hyperglobulinemia. She suffered from chronic cough for 3 weeks. Chest computed tomography （CT） demonstrated a multiloculated cystic mass in mediastinum prevascular space and multiple lung cysts. Laboratory exam of autoimmune markers showed positive of antinuclear antibody （ANA）, Sjtgren＇s syndrome A （SSA）, Sjtgren＇s syndrome B （SSB）, and rheumatoid factors （RF）. Thymectomy with lymph node dissection was performed. The pathology report revealed thymic extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue. Under immunohistochemical stains, CD20 and Bcl-2 were positive. No evidence of recurrence of disease was found.

Concomitant extrahepatic autoimmune diseases do not compromise the long-term outcomes of primary biliary cholangitis

Background:Primary biliary cholangitis(PBC)patients often have concomitant extrahepatic autoimmune(EHA)diseases including Sjögren’s syndrome(SS),systemic sclerosis(SSc),rheumatoid arthritis(RA),and autoimmune thyroid disease.The present study aimed to describe the prevalence of EHA diseases in PBC and explore the impact of EHA diseases on the long-term outcomes of PBC in Chinese patients.Methods:Medical records of PBC patients diagnosed in our institute were retrospectively reviewed.Pa-tients were followed up by a standardized telephone interview.The endpoints were defined as liver-related death and/or liver transplantation.Results:Totally 247 of the 985(25.1%)PBC patients enrolled in the study had at least one concomi-tant EHA disease.Sjögren’s syndrome(n=140,14.2%)was the most frequent one,followed by rheuma-toid arthritis(RA)(n=56,5.7%)and Hashimoto’s thyroiditis(n=45,4.6%).Patients with EHA dis-eases were more common in females(P<0.001)and in those with a family history of autoimmune disease(P=0.017).Overall,no differences were found between PBC patients with and without EHA dis-eases in terms of biochemical response rates to ursodeoxycholic acid,the incidence of hepatic events,or transplant-free survival.RA and EHA≥2 were protective factors for hepatic events in univariate Cox analysis,but the results became insignificant in multivariate analysis.Conclusions:Concomitant EHA diseases were common in PBC patients but did not compromise the long-term outcomes of PBC.

Clinical spectrum of primary ciliary dyskinesia in childhood

Although the triad of bronchiectasis, sinusitis and situs inversus was first described by Kartagener in 1933, the clinical spectrum of primary ciliary dyskinesia is still under investigation. Heterotaxy defects as well as upper and lower respiratory tract symptoms are the main manifestations in childhood. It is now recognized that situs inversus is encountered in only half of patients. The first lower respiratory symptoms may be present from infancy as neonatal respiratory distress. The most common lower airway manifestations are chronic wet cough, recurrent pneumonia and therapy resistant wheezing. Patients are at risk of developing bronchiectasis which may even be the presenting finding due to delayed diagnosis. Upper respiratory tract infections such as nasal congestion, nasal drainage and recurrent sinusitis as well as otologic manifestations such as otitis media or otorrhea with conductive hearing loss are also often encountered. It seems that the type of ciliary ultrastructure defects and the involved mutated genes are associated to some extent to the clinical profile. The disease, even in nowadays, is not recognized at an early age and the primary care clinician should have knowledge of its clinical spectrum in order to select appropriately the children who need further investigation for the diagnosis of this disorder.
