Clinical analysis of primary Sjögren's syndrome complicating anemia

Recommendations on cutaneous and hematological manifestations of Sjögren's disease by the Brazilian Society of Rheumatology

Sjogren's disease (SjD) is an autoimmune disease that is characterized not only by the sicca symptoms it causes but also by its systemic nature, which is capable of several and not yet fully understood extraglandular manifestations. To gain a clearer understanding of these manifestations as well as a better practical approach, a panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis on the identification of epidemiologic and clinical features of the extraglandular manifestations present in ESSDAI (EULAR Sjogren´s syndrome disease activity index), followed by a voting panel with recommendations for clinical practice. This publication is complementary to others already published and covers cutaneous and hematological manifestations, with prevalence data generated by a meta-analysis of 13 clinical or laboratory manifestations and 6 clinical management recommendations.

Plummer-Vinson syndrome in primary Sjögren syndrome: a case-based review

This study aimed to describe a patient with Sjögren syndrome who developed Plummer-Vinson syndrome, and to review the literature and describe shared aspects of this rare association. A systematic screening of articles was conducted in PubMed/MEDLINE, LILACS, SciELO, Scopus, Web of Science, and Cochrane, dating 1940 to 2020. All the articles included the association between Sjögren syndrome and Plummer-Vinson syndrome. No language restriction was applied. The following terms were used: "Sjögren syndrome" or "sicca syndrome" and "Plummer-Vinson syndrome" or "Paterson-Kelly syndrome." We performed our analysis by adding our present case, with a total of 4 cases. Three out of four were female (75%), age varied from 56 to 58 years old. In 2 cases, Sjögren syndrome preceded Plummer-Vinson syndrome diagnosis, and in 1 report, Plummer-Vinson syndrome appeared before Sjögren syndrome. Disease duration varied from 7 to 20 years. In two cases, autoantibodies were available, and antinuclear antibodies and anti-Ro/SS-A were positive in both, and anti-La/SS-B in one of them was associated with anti-dsDNA; however, no data regarding lupus was available in the article. Treatment involved iron supplementation in 3/3. Two out of three received parenteral iron supplementation, and in these two cases, mechanical esophageal dilatation was needless. In the other case, an additional endoscopic esophageal dilatation was necessary to receive the oral iron supplement. All 3 cases had a good outcome. This case illustrates a patient with Sjögren syndrome who developed the rare Plummer-Vinson syndrome. In Sjögren syndrome, the presence of iron-deficiency anemia, dysphagia, and weight loss should alert the physician to search for associated Plummer-Vinson syndrome.

Clinical Characteristics and Prognosis of Concomitant Primary Biliary Cholangitis and Autoimmune Diseases: A Retrospective Study

Objectives

Diagnosis and treatment of primary biliary cholangitis (PBC) are often complicated by hepatic and/or extrahepatic manifestations, which in turn affect the natural course and prognosis of PBC. This study evaluated the clinical characteristics and prognosis of PBC co-occurring with intrahepatic and extrahepatic autoimmune disease (AID).

Methods

Clinical data of patients with PBC who were admitted to the Beijing Ditan Hospital from September 2008 to December 2014 were retrospectively reviewed, assessed for other autoimmune diseases, and analyzed statistically. All patients received ursodeoxycholic acid (UDCA) treatment.

Results

Data from 505 patients were evaluated. Approximately 35.0% of patients had at least one additional AID. AIDs included Sjögren's syndrome (SS; 26.3%), autoimmune hepatitis (AIH; 7.1%), rheumatoid arthritis (RA; 1.4%), hypothyroidism (0.8%), Graves's thyroiditis (0.6%), systemic lupus erythematosus (SLE; 0.4%), and Hashimoto's thyroiditis (0.2%). No differences in response rates of UDCA were found between the PBC group and the PBC-SS group or PBC complicated with AID group (both P > 0.05). White blood cell (WBC, RR = 1.072, 95% CI: 1.016-1.130, P=0.011), platelet counts (PLT, RR = 0.995, 95% CI: 0.992-0.998, P=0.003), and prothrombin time and international normalized ratio (PT/INR, RR = 1.799, 95% CI: 1.010-3.206, P=0.046) were independent prognostic factors in patients with PBC. The overall survival time of patients in PBC-AIH and PBC-SS groups was shorter than that of those with PBC (P < 0.001).

Conclusions

AIH was the most common in hepatic comorbidity. SS was the most frequent extrahepatic comorbidity. WBC, PLT, and PT/INR were independent prognostic factors in patients with PBC. AID coexisted with PBC impaired patients' survival.

Primary Sjogren's syndrome presenting as autoimmune cytopenia

Sjogren's syndrome (SS) is a chronic systemic autoimmune disease, characterized by lymphocytic infiltration of lacrimal and salivary glands. Although extra glandular manifestations are uncommon, they can occur with the musculoskeletal, renal, pulmonary and hematological disease. We report the case of a 35-year-old woman presented to us with persistent unexplained bicytopenia (anemia and thrombocytopenia). Antinuclear antibody and direct Coombs test were positive. Anti-Ro/SSA and anti-La/SSB antibodies were also positive in high titer. The final diagnosis of primary SS with autoimmune cytopenia was made. Cytopenias in SS are rarely reported. Our case illustrates that clinically significant cytopenias may present as an extraglandular manifestation of SS.

Clinical Profile and Significance of Mucocutaneous Lesions of Primary Sjögren's Syndrome: A Large Cross-sectional Study with 874 Patients

Background:

Mucocutaneous lesions are common features of primary Sjögren's syndrome (pSS), but only a few studies have focused on them. To demonstrate the profile of mucocutaneous lesions of pSS and further explore their potential clinical significance, we performed a cross-sectional study on 874 patients.

Methods:

Demographic data, clinical manifestations, and laboratory results of 874 pSS patients were collected. Patients were divided into two groups according to the presence of mucocutaneous lesions. Differences in primary symptoms and systemic impairments between the two groups were analyzed. Results of laboratory tests were also compared after excluding those who had taken corticosteroid from both groups. One-year follow-up was done, and occurrences of various new complications were compared.

Results:

Among the 874 pSS patients, 181 patients had mucocutaneous lesions, accounting for 20.7%. Multiple mucocutaneous manifestations were displayed, and the top four most common types of lesions were purpuric eruptions (39.8%), urticaria (23.8%), Raynaud's phenomenon (14.9%), and angular stomatitis (9.9%). Incidences of pulmonary interstitial fibrosis, pulmonary bullae, leukopenia, and anemia were significantly higher among patients with mucocutaneous lesions (P < 0.05). Increase in IgG and decrease in C4 among patients with mucocutaneous lesions displayed statistical significance after excluding patients from both groups who had taken corticosteroid (P < 0.05). After one-year follow-up, patients with mucocutaneous lesions presented a slightly higher incidence of new complications compared to those without.

Conclusions:

Mucocutaneous manifestations of pSS patients were common and diverse. Patients with mucocutaneous manifestations had more systemic damages, higher level of IgG, and lower level of serum C4, suggesting a higher activity of the primary disease.

Sjogren's syndrome complicating pancytopenia, cerebral hemorrhage, and damage in nervous system: A case report and literature review

RATIONALE

Sjogren's syndrome(SS) is a chronic autoimmune disease, which damages exocrine glands especially salivary and lacrimal glands, with xerostomia and xerophthalmia as common symptoms.

PATIENT CONCERNS

We report a case of a 49-year-old woman presented with pancytopenia. Her laboratory examinations lead us diagnose her as Sjogren's syndrome complicating pancytopenia. She had neurological symptoms during her treatment, which represent only 4.5% of Sjogren's syndrome complicating damage in nervous system.

DIAGNOSES

Sjogren's syndrome complicating pancytopenia.

INTERVENTIONS

Dexamethasone (40mg QD for 4 days) and immunoglobulin (25g QD for 2 days) were administered for intensive treatment followed by oral methylprednisolone 40mg QD as maintenance treatment. Total glucosides of paeony 0.6g TID and danazol 0.2g BID per os were given. We also gave her Piperacillin-tazobactam and moxifloxacin for anti-infection and Fluconazole for anti-fungal therapy, as well as other supportive treatments.

OUTCOMES

Follow-up of the patient observed the normalization of peripheral blood cell count, immunity indices and neurological examinations 6 months after discharge.

LESSONS

For patients presented with blood system abnormalities unilineage or multiple-lineage cytopenia in particular, history investigations and relevant examinations should be considered to exclude the existence of autoimmune diseases like Sjogren's syndrome.

Primary Sjögren syndrome presenting with hemolytic anemia and pure red cell aplasia following delivery due to Coombs-negative autoimmune hemolytic anemia and hemophagocytosis

A 36-year-old woman presented with hemolytic anemia without a reticulocyte response 38 days after delivery. A marked reduction in erythroid cells and an increase in macrophages with active hemophagocytosis were noted in the bone marrow. While conventional Coombs' tests were negative, the level of red blood cell (RBC)-bound immunoglobulin G (IgG) was increased. The patient was diagnosed with primary Sjögren syndrome (pSS) based on her symptoms, positive anti-SS-A antibodies, Coombs-negative autoimmune hemolytic anemia and pure red cell aplasia associated with RBC-bound IgG and hemophagocytosis. The unique presentation was considered to be a consequence of immunological derangement associated with pSS, pregnancy and delivery.
