Successful treatment of a patient with primary Sjögren's syndrome complicated with pericarditis during pregnancy

Cardiac Manifestations of Sjogren's Syndrome: A Review of Literature

Sjogren's syndrome (SS) is a chronic inflammatory disorder of the exocrine glands. It is characterized by a lymphocytic infiltrate in the lacrimal and salivary glands causing keratoconjunctivitis sicca and xerostomia. Extra-glandular involvement may be present in about one-third of patients with primary Sjogren's syndrome (pSS). The most commonly affected organs are the thyroid, lungs, gastrointestinal tract, kidneys, skin, and nervous system. Cardiac manifestations of Sjogren's syndrome are rare and not well-described in the current literature. Most of the evidence is present in the form of case reports and small case series. However, recent studies have shown that patients with Sjogren's syndrome (SS) seem to have a greater overall risk of cardiovascular (CV) events. Although not conventionally considered a feature of the disease, cardiac manifestations can lead to increased morbidity and mortality in this patient population. In this review article, we study the association between cardiac diseases and primary Sjogren's syndrome.

Severe extra-glandular involvement and pleural effusions complicating primary Sjogren's syndrome: a case report

Background

Sjogren’s syndrome, an autoimmune disease of the exocrine glands, results in keratoconjunctivitis sicca, xerostomia, and dental caries. It is often overlooked, considered by clinicians to be a benign disease. However, it can cause life-threatening extra-glandular complications that affect multiple organ systems.

Case presentation

Here we present a 78-year-old Caucasian woman with a history of primary Sjogren’s syndrome (pSS) whose symptoms of keratoconjunctivitis sicca were managed managed conservatively. She was evaluated for sub-acute shortness of breath. Imaging showed severe bronchiectasis with features of lymphocytic interstitial pneumonia. She also had exudative bilateral pleural effusions and skin ulcers, likely vasculitic in origin. The workup was significant for anti-Ro antibody, pancytopenia, hypocomplementia, cryoglobulinemia and monoclonal gammopathy, all of which reflect disease severity. Although there was no evidence of malignancy, she developed B-cell non-Hodgkin lymphoma during follow-up.

Conclusions

Primary Sjogren’s syndrome can result in severe multi-organ disease. Pleural effusions are a rare complication of pSS, with only ten cases reported in the literature over the last 30 years, and tend to respond well to steroids. Prognostic biomarkers for disease severity include hypocomplementia, cryoglobulinemia, monoclonal gammopathy, and hypergammaglobulinemia. In this report we review the literature and the management of the disease.

Lung complications of Sjogren syndrome

Primary Sjogren syndrome (pSS) is a systemic autoimmune disease characterised by lymphocytic infiltration of exocrine glands and by a number of systemic manifestations, including those regarding the lung. Pulmonary involvement in pSS includes interstitial lung disease (ILD) and airway disease, together with lymphoproliferative disorders.

Patients with pSS-ILD report impaired health-related quality of life and a higher risk of death, suggesting the importance of early diagnosis and treatment of this type of pulmonary involvement. In contrast, airway disease usually has little effect on respiratory function and is rarely the cause of death in these patients.

More rare disorders can be also identified, such as pleural effusion, cysts or bullae.

Up to date, available data do not allow us to establish an evidence-based treatment strategy in pSS-ILD. No data are available regarding which patients should be treated, the timing to start therapy and better therapeutic options. The lack of knowledge about the natural history and prognosis of pSS-ILD is the main limitation to the development of clinical trials or shared recommendations on this topic. However, a recent trial showed the efficacy of the antifibrotic drug nintedanib in slowing progression of various ILDs, including those in pSS patients.

Primary Sjogren syndrome is a systemic autoimmune disease with a possible lung involvement, that it appears as polymorphic, including interstitial lung disease, airway disease and lymphoproliferative disorders with different degree of severityhttps://bit.ly/3akjk4b

Outcome of Pregnancy in Italian Patients with Primary Sjögren Syndrome

Objective.

To investigate pregnancy and fetal outcomes in patients with primary Sjögren syndrome (pSS).

Methods.

An obstetric history of 36 women with established diagnosis of pSS at pregnancy was obtained from a multicenter cohort of 1075 patients. In a subgroup case-control analysis, 12 deliveries in patients with pSS were compared with 96 control deliveries.

Results.

Thirty-six women (31 with anti-SSA/Ro and/or anti-SSB/La antibodies) with an established diagnosis of pSS had 45 pregnancies with the delivery of 40 newborns. Two miscarriages, 2 fetal deaths, and 1 induced abortion were recorded. Mean age at the first pregnancy was 33.9 years; mean number of pregnancies was 1.25; 18/40 (45%) cesarean births were delivered; mean pregnancy length was 38.5 weeks (range 32–43), with 6 preterm deliveries. The mean Apgar score at 5 min was 8.9, mean birthweight was 2920 g (range 826–4060 g). Congenital heart block (CHB) occurred in 2/40 (5%) newborns. The reported rate of breastfeeding for at least 1 month was 60.5%. In 4/40 pregnancies (10%) a flare of disease activity was observed within a year from delivery. In the case-control subgroup analysis, 12 deliveries were compared with 96 controls and no significant differences were found.

Conclusion.

Patients with pSS can have successful pregnancies, which might be followed by a mild relapse. CHB was the only cause of death for offspring of mothers with pSS.
