SAT0536 IMMUNE CHECKPOINT INHIBITOR THERAPY IN PATIENTS WITH PREEXISTING SARCOIDOSIS

Background:

Immune checkpoint inhibitors (ICI) have changed the treatment landscape of many cancer types, but are also associated with development of immune-related adverse events, includingde novosarcoid like reactions. However, little is known about the use of ICI therapy in patients with preexisting sarcoidosis as patients with preexisting autoimmune diseases have been systematically excluded from clinical trials of ICI therapy due to concerns of heightened toxicities. Emerging research suggests that ICI therapy can be considered in some patients with autoimmune diseases.1

Objectives:

To determine the risk of sarcoidosis exacerbation or flare in patients with preexisting sarcoidosis receiving ICI therapy.

Methods:

We conducted a retrospective cohort study of patients seen at The University of Texas MD Anderson Cancer Center between 2016-2019. Patients were included in the cohort if they received one of 7 ICI therapies (ipilimumab, nivolumab, pembrolizumab, durvalumab, avelumab, atezolizumab, or cemiplimab) and had an International Classification of Disease version 10 code of sarcoidosis (D86.*), prior to the ICI initiation, with diagnosis confirmed in medical record by treating physicians. A sarcoidosis diagnosis was considered “possible” if the medical record documented a history of sarcoidosis, “probable” if a history of biopsy proven sarcoidosis was mentioned, and “definitive” if histological evidence was available. Frequency of flares and outcomes of patients after receiving ICI were collected.

Results:

During the study timeframe a total of 32 patients with preexisting sarcoidosis received ICI therapy. Nine patients (28%) had a definitive diagnosis of sarcoidosis, 12 (37%) had a probable diagnosis and 11 (35%) had a possible diagnosis of sarcoidosis. The mean time between diagnosis of sarcoidosis and initiation of ICI therapy was 13 years (range: <1 to 51 years). Twenty-seven patients (84%) received monotherapy and five patients (16%) received combination or sequential ICI therapy. Of the 32 patients, one patient with a 20-year remote history of sarcoidosis, never treated, developed a clinically symptomatic exacerbation of sarcoidosis one month after the initial dose of atezolizumab, with increased hilar nodules on imaging, skin nodules, arthritis and uveitis. Biopsy of a lymph node showed non-necrotizing granulomas, and biopsy of the skin panniculitis. The patient also developed colitis thought to be an immune-related adverse event. Atezolizumab was discontinued after 3 doses. Patient was treated with prednisone and azathioprine.

Conclusion:

Patients with a remote history of stable sarcoidosis at the time of ICI therapy infrequently develop a flare of their sarcoidosis. The risk of flares in patients with active sarcoidosis requiring immunosuppression at the time of ICI initiation is unknown.

Weight of salivary gland ultrasonography compared to other items of the 2016 ACR/EULAR classification criteria for Primary Sjögren's syndrome

OBJECTIVE

Major salivary gland ultrasonography (SGUS) is widely used for the diagnosis of primary Sjögren's syndrome (pSS). Our objective was to assess the contribution of SGUS compared to other items of the 2016 ACR/EULAR pSS classification criteria, based on expert opinion.

METHODS

A secure web-based relational database was used by 24 experts from 14 countries to assess 512 realistic vignettes developed from data of patients with suspected pSS. Each vignette provided classification criteria items and information on history, clinical symptoms and SGUS findings. Each expert assessed 64 vignettes, and each vignette was assessed by 3 experts. A diagnosis of pSS was defined according to at least 2 of 3 experts. Validation was performed in the independent French DiapSS cohort of patients with suspected pSS.

RESULTS

A criteria-based pSS diagnosis and SGUS findings were independently associated with an expert diagnosis of pSS (P < 0.001). The derived diagnostic weights of individual items in the 2016 ACR/EULAR criteria including SGUS were as follows: anti-SSA, 3; focus score ≥ 1, 3; SGUS score ≥ 2, 1; positive Schirmer's test, 1; dry mouth, 1; and salivary flow rate < 0.1 mL/min, 1. The corrected C statistic area under the curve for the new weighted score was 0.96. Adding SGUS improves the sensitivity from 90.2 % to 95.6% with a quite similar specificity 84.1% versus 82.6%. Results were similar in the DiapSS cohort: adding SGUS improves the sensitivity from 87% to 93%.

CONCLUSION

SGUS had similar weight compared to minor items, and its addition improves the performance of the 2016 ACR/EULAR classification criteria.

Systemic phenotype of sarcoidosis associated with radiological stages. Analysis of 1230 patients

BACKGROUND

To analyze the association between Scadding radiological stages of sarcoidosis at diagnosis and the disease phenotype (epidemiology, clinical presentation and extrathoracic involvement) in one of the largest cohorts of patients with sarcoidosis reported from southern Europe.

METHODS

The SARCOGEAS-Study Group includes a multicenter database of consecutive patients diagnosed with sarcoidosis according to the WASOG 1999 criteria. Extrathoracic disease at diagnosis was defined according to the 2014 instrument and the clusters proposed by Schupp et al. RESULTS: We analyzed 1230 patients (712 female, mean age 47 yrs.) who showed the following Scadding radiologic stages at diagnosis: stage 0 (n = 98), stage I (n = 395), stage II (n = 500), stage III (n = 195) and stage IV (n = 42). Women were overrepresented in patients presenting with extrathoracic/extrapulmonary disease, while the diagnosis was made at younger ages in patients presenting with BHL, and at older ages in those presenting with pulmonary fibrosis (q values <0.05). Multivariable adjusted analysis showed that patients presenting with pulmonary involvement (especially those with stages II and III) had a lower frequency of concomitant systemic involvement in some specific extrathoracic clusters (cutaneous-adenopathic/musculoskeletal, ENT and neuro-ocular/OCCC) but a higher frequency for others (hepatosplenic), in comparison with patients with extrapulmonary involvement (stages 0 and I). The presence of either BHL or fibrotic lesions did not influence the systemic phenotype of patients with pulmonary involvement.

CONCLUSIONS

The key determinant associated with a differentiated systemic phenotype of sarcoidosis at diagnosis was interstitial pulmonary involvement rather than the individual Scadding radiological stage.

Prognostic markers of lymphoma development in primary Sjögren syndrome

Sjögren syndrome is a systemic autoimmune disease that principally affects women between the fourth and sixth decades of life who present with sicca symptomatology caused by dryness of the main mucosal surfaces. The clinical spectrum of Sjögren syndrome extends from dryness to systemic involvement. Since 1978, Sjögren syndrome has been closely associated with an enhanced risk of lymphoma, one of the most severe complications a patient may develop. Primary Sjögren syndrome patients have a 10-44-fold greater risk of lymphoma than healthy individuals, higher than that reported for systemic lupus erythematosus and rheumatoid arthritis. The close link between lymphoma and Sjögren syndrome is clearly exemplified by the very specific type of lymphoma arising in Sjögren syndrome patients, mainly low-grade B-cell lymphomas (predominantly a marginal zone histological type) with primary extranodal involvement of the major salivary glands (overwhelmingly parotid), with a primordial role of cryoglobulinemic-related markers (both clinical and immunological). The most recent studies support a higher number of risk factors detected in an individual leads to a higher lymphoma risk. A close follow-up of high-risk groups with longitudinal assessments of all known risk factors, including cryoglobulin-related markers and EULAR Sjögren's syndrome disease activity index measurement in particular, is mandatory.

Extrahepatic manifestations associated with Chronic Hepatitis C Virus Infection

Chronic hepatitis C virus (HCV) infection has been associated with both organ-specific and systemic autoimmune diseases, with cryoglobulinemia being the most frequent associated disease. Experimental, virologic, and clinical evidence have demon-strated a close association between HCV infection and some systemic autoimmune diseases, especially Sjögren's syndrome, but also rheumatoid arthritis and lupus. A higher prevalence of hematological processes has also been described in patients with HCV infection, including cytopenias and lymphoproliferative disorders (B-cell lymphoma). In addition, patients with chronic HCV infection have a higher frequency of other extrahepatic manifestations including endocrine, metabolic and cardiovascular disorders that may worse the prognosis of patients, along with neuropsychiatric manifestations and general symptoms that have a significant influence on the quality of life of the patient. Direct-acting antiviral therapies (DAAs) that have recently begun to be used are providing the opportunity to effectively cure chronic HCV infection and reduce the burden of both hepatic and extrahepatic complications.

Mycophenolate mofetil in patients with hepatitis C virus infection

Diagnosis and treatment of hepatitis C virus (HCV) -related autoimmune features has become a clinical challenge in HCV-infected patients, in whom chronic liver disease associated with severe autoimmune features may contribute to a very poor prognosis. Both antiviral and immunosuppressive therapies, either alone or in combination, seem likely to have a key role. Based on the experience of mycophenolate mofetil (MMF) use in HCV patients receiving organ transplantation, this new immunosuppressive agent might represent a safe and effective therapeutic option to treat HCV-related extrahepatic features. Recent data are available for the use of MMF in HCV patients with autoimmune manifestations, mainly for autoimmune cytopenias and vasculitic features. MMF may be used as monotherapy or in association with other drugs for cases of HCV-related autoimmune diseases refractory or intolerant to common immunosuppressive treatments, allowing the reduction of the drug dosage and avoiding serious side effects.

Autoimmune congenital heart block: complex and unusual situations

Autoimmune congenital heart block (ACHB) is an immune-mediated cardiac disease included among the manifestations collectively referred to as neonatal lupus. The placental transference of maternal Ro/La autoantibodies may damage the conduction tissues during fetal development leading to blocking of signal conduction at the atrioventricular (AV) node in an otherwise structurally normal heart. Irreversible complete AV block is the main cardiac manifestation of ACHB, but some babies may develop endocardial fibroelastosis, valvular insufficiency, and/or frank cardiomyopathies with significantly reduced cardiac function requiring transplant. The severity of ACHB is illustrated by a global mortality rate of 20% and pacemaker rates of at least 64%, often within the first year of life. This review analyses the main complex and/or unusual clinical situations associated with ACHB, including unusual maternal immunological profiles, infrequent maternal autoimmune diseases, cardiac damage unrelated to AV block, fetal invasive management, late complications after birth, risk of congenital heart block (CHB) in ovodonation and in vitro fertilization techniques, the role of maternal features other than autoimmunity, the influence of the birth order or the risk of CHB in twins and triplets.

Cardiovascular events prior to or early after diagnosis of systemic lupus erythematosus in the systemic lupus international collaborating clinics cohort

Objective

To describe the frequency of myocardial infarction (MI) prior to the diagnosis of systemic lupus erythematosus (SLE) and within the first 2 years of follow-up.

Methods

The systemic lupus international collaborating clinics (SLICC) atherosclerosis inception cohort enters patients within 15 months of SLE diagnosis. MIs were reported and attributed on a specialised vascular event form. MIs were confirmed by one or more of the following: abnormal ECG, typical or atypical symptoms with ECG abnormalities and elevated enzymes (≥2 times upper limit of normal), or abnormal stress test, echocardiogram, nuclear scan or angiogram. Descriptive statistics were used.

Results

31 of 1848 patients who entered the cohort had an MI. Of those, 23 patients had an MI prior to SLE diagnosis or within the first 2 years of disease. Of the 23 patients studied, 60.9% were female, 78.3% were Caucasian, 8.7% black, 8.7% Hispanic and 4.3% other. The mean age at SLE diagnosis was 52.5±15.0 years. Of the 23 MIs that occurred, 16 MIs occurred at a mean of 6.1±7.0 years prior to diagnosis and 7 occurred within the first 2 years of follow-up. Risk factors associated with early MI in univariate analysis are male sex, Caucasian, older age at diagnosis, hypertension, hypercholesterolaemia, family history of MI and smoking. In multivariate analysis only age (OR=1.06 95% CI 1.03 to 1.09), hypertension (OR=5.01, 95% CI 1.38 to 18.23), hypercholesterolaemia (OR=4.43, 95% CI 1.51 to 12.99) and smoking (OR=7.50, 95% CI 2.38 to 23.57) remained significant risk factors.

Conclusions

In some patients with lupus, MI may develop even before the diagnosis of SLE or shortly thereafter, suggesting that there may be a link between autoimmune inflammation and atherosclerosis.

Registry of the Spanish Network for Systemic Sclerosis: Survival, Prognostic Factors, and Causes of Death

Systemic sclerosis (SSc) is a rare, multisystem disease showing a large individual variability in disease progression and prognosis. In the present study, we assess survival, causes of death, and risk factors of mortality in a large series of Spanish SSc patients. Consecutive SSc patients fulfilling criteria of the classification by LeRoy were recruited in the survey. Kaplan-Meier and Cox proportional-hazards models were used to analyze survival and to identify predictors of mortality. Among 879 consecutive patients, 138 (15.7%) deaths were registered. Seventy-six out of 138 (55%) deceased patients were due to causes attributed to SSc, and pulmonary hypertension (PH) was the leading cause in 23 (16.6%) patients. Survival rates were 96%, 93%, 83%, and 73% at 5, 10, 20, and 30 years after the first symptom, respectively. Survival rates for diffuse cutaneous SSc (dcSSc) and limited cutaneous SSc were 91%, 86%, 64%, and 39%; and 97%, 95%, 85%, and 81% at 5, 10, 20, and 30 years, respectively (log-rank: 67.63, P < 0.0001). The dcSSc subset, male sex, age at disease onset older than 65 years, digital ulcers, interstitial lung disease (ILD), PH, heart involvement, scleroderma renal crisis (SRC), presence of antitopoisomerase I and absence of anticentromere antibodies, and active capillaroscopic pattern showed reduced survival rate. In a multivariate analysis, older age at disease onset, dcSSc, ILD, PH, and SRC were independent risk factors for mortality. In the present study involving a large cohort of SSc patients, a high prevalence of disease-related causes of death was demonstrated. Older age at disease onset, dcSSc, ILD, PH, and SRC were identified as independent prognostic factors.

Systemic activity and mortality in primary Sjögren syndrome: predicting survival using the EULAR-SS Disease Activity Index (ESSDAI) in 1045 patients

OBJECTIVE

To score systemic activity at diagnosis and correlate baseline activity with survival in a large cohort of patients with primary Sjögren syndrome (SS).

PATIENTS AND METHODS

We include 1045 consecutive patients who fulfilled the 2002 classification criteria for primary SS. The clinical and immunological characteristics and level of activity (EULAR-SS Disease Activity Index (ESSDAI) scores) were assessed at diagnosis as predictors of death using Cox proportional hazards regression analysis adjusted for age at diagnosis. The risk of death was calculated at diagnosis according to four different predictive models.

RESULTS

After a mean follow-up of 117 months, 115 (11%) patients died. The adjusted standardised mortality ratio for the total cohort was 4.66 (95% CI 3.85 to 5.60), and survival rates at 5, 10, 20 and 30 years were 96%, 90%, 81% and 60%, respectively. The main baseline factors associated with overall mortality in the multivariate analysis were male gender, cryoglobulins and low C4 levels. Baseline activity in the constitutional, pulmonary and biological domains was associated with a higher risk of death. High activity in at least one ESSDAI domain (HR 2.14), a baseline ESSDAI score ≥14 (HR 1.85) and more than one laboratory predictive marker (lymphopenia, anti-La, monoclonal gammopathy, low C3, low C4 and/or cryoglobulins) (HR 2.82) were associated with overall mortality; these HRs increased threefold to 10-fold when the analysis was restricted to mortality associated with systemic disease.

CONCLUSIONS

Patients with primary SS, who present at diagnosis with high systemic activity (ESSDAI ≥14) and/or predictive immunological markers (especially those with more than one), are at higher risk of death.

Annular erythema in primary Sjögren’s syndrome: description of 43 non-Asian cases

Objective

The objective of this paper is to evaluate the prevalence and characterize the main epidemiological, clinical and immunological features of annular erythema (AE) in non-Asian patients with primary Sjögren’s syndrome (SS).

Methods

We carried out a retrospective study searching for AE in 377 Spanish patients with primary SS fulfilling the 2002 American-European criteria. In addition, we searched PubMed (1994–2012) using the MeSH terms “annular erythema” and “primary Sjögren’s syndrome” for additional cases. All cases with AE reported in patients with SS associated with systemic lupus erythematosus were excluded.

Results

In our Spanish cohort, we found 35 (9%) patients diagnosed with AE. All were white females, with a mean age of 47 years at diagnosis of AE. AE preceded diagnosis of SS in 27 (77%) patients. Cutaneous AE lesions involved principally the face and upper extremities. All patients reported photosensitivity, with cutaneous flares being reported during the warmest months in 93% of patients. Immunological markers consisted of anti-Ro/La antibodies in 31 (89%) patients. In the literature search, we identified eight additional non-Asian patients with primary SS diagnosed with AE. In comparison with 52 Asian patients, the 43 non-Asian patients with AE related to primary SS were more frequently women (100% vs 78%, p = 0.008), and cutaneous lesions were less frequently reported in the face (55% vs 81%, p = 0.045) and more frequently in the neck (40% vs 14%, p = 0.041). Immunologically, non-Asian patients had a lower frequency of anti-Ro antibodies and a higher frequency of negative Ro/La antibodies, although the differences were not statistically significant.

Conclusion

AE is not an exclusive cutaneous feature of Asian patients with primary SS. In addition to the characteristic cutaneous expression, AE has a very specific clinical and immunological profile: often presenting before the fulfillment of SS criteria, overwhelmingly associated with anti-Ro antibodies but weakly associated with other immunological markers and the main systemic SS-related features.

[Recommendations on the use of belimumab in systemic lupus erythematosus. GEAS-SEMI Clinical Practice Guide]

Biological therapies are based on the administration of various types of synthetic molecules related to the immune response. Their use has spread in recent years to the field of systemic autoimmune diseases, particularly to systemic lupus erythematosus (SLE). Until 2011, these diseases were not included in the therapeutic indications approved by international regulatory agencies. Therefore, the use of biological therapies was restricted to clinical trials and to compassionate use for cases refractory to standard treatments (off-label use), which require the approval of the Health Ministry. In 2011, belimumab, a human monoclonal antibody that specifically binds to the soluble form of the protein human B lymphocyte stimulator BlyS, was approved for use in patients with SLE. Because the clinical information on the use of this new drug in patients with SLE has only been obtained from the results of randomized trials, the Study Group of Autoimmune Diseases (GEAS) of the Spanish Society of Internal Medicine (SEMI) has developed therapeutic guidelines. These guidelines are based on the current scientific evidence on the use of belimumab in SLE patients in the clinical practice.

White matter abnormalities in primary Sjögren syndrome

OBJECTIVE

To describe the main characteristics of patients with primary Sjögren syndrome (SS) and white matter abnormalities (WMA) seen by a specialist SS unit.

METHODS

The study cohort included 321 consecutive patients fulfilling the 2002 classification criteria for primary SS. We retrospectively analyzed the results of neuroimaging studies performed in patients who presented with neurological symptoms. Patients were further evaluated by three neurologists to determine fulfillment of the McDonald criteria for the diagnosis of multiple sclerosis (MS).

RESULTS

Fifty-one (16%) patients had at least one neuroimaging study, and 25 of these had WMA. WMA were classified as vascular pathological changes in 21 patients: 10 had multiple small focal lesions, 7 had beginning confluence of lesions and 4 had diffuse involvement of the entire region. WMA were classified as inflammatory/demyelinating lesions (MS-like) in 4 patients who fulfilled the MRI Barkhof criteria. Patients with inflammatory/demyelinating lesions were younger (53.7 vs. 73.5 years, P = 0.001) and had a lower frequency of hypertension (25% vs. 86%, P = 0.031) and altered glomerular filtration rate (0% vs. 70%, P = 0.047) in comparison with patients with vascular lesions. The multivariate age-sex adjusted model including the seven variables which were statistically significant in the univariate analysis (antimalarial therapy, leukopenia, anti-La/SSB antibodies, diabetes, hypertension, metabolic syndrome and HDL-c levels) identified hypertension (P = 0.019) and HDL-c levels (P = 0.032) as independent predictors of WMA in primary SS patients.

CONCLUSION

Neuroimaging studies disclosed WMA in 49% of patients with primary SS and suspected neurological involvement. WMA were identified as vascular pathological changes in 80% of the patients, and hypertension and HDL-c levels as predictive factors for this association.

Autoantibodies as biomarkers for the prediction of neuropsychiatric events in systemic lupus erythematosus

OBJECTIVE

Neuropsychiatric events occur unpredictably in systemic lupus erythematosus (SLE) and most biomarker associations remain to be prospectively validated. This study examined a disease inception cohort of 1047 SLE patients to determine which autoantibodies at enrolment predicted subsequent neuropsychiatric events.

METHODS

Patients with a recent SLE diagnosis were assessed prospectively for up to 10 years for neuropsychiatric events using the American College of Rheumatology case definitions. Decision rules of graded stringency determined whether neuropsychiatric events were attributable to SLE. Associations between the first neuropsychiatric event and baseline autoantibodies (lupus anticoagulant (LA), anticardiolipin, anti-β(2) glycoprotein-I, anti-ribosomal P and anti-NR2 glutamate receptor) were tested by Cox proportional hazards regression.

RESULTS

Disease duration at enrolment was 5.4 ± 4.2 months, follow-up was 3.6 ± 2.6 years. Patients were 89.1% female with mean (±SD) age 35.2 ± 13.7 years. 495/1047 (47.3%) developed one or more neuropsychiatric event (total 917 events). Neuropsychiatric events attributed to SLE were 15.4% (model A) and 28.2% (model B). At enrolment 21.9% of patients had LA, 13.4% anticardiolipin, 15.1% anti-β(2) glycoprotein-I, 9.2% anti-ribosomal P and 13.7% anti-NR2 antibodies. LA at baseline was associated with subsequent intracranial thrombosis (total n=22) attributed to SLE (model B) (HR 2.54, 95% CI 1.08 to 5.94). Anti-ribosomal P antibody was associated with subsequent psychosis (total n=14) attributed to SLE (model B) (HR 3.92, 95% CI 1.23 to 12.5, p=0.02). Other autoantibodies did not predict neuropsychiatric events.

CONCLUSION

In a prospective study of 1047 recently diagnosed SLE patients, LA and anti-ribosomal P antibodies are associated with an increased future risk of intracranial thrombosis and lupus psychosis, respectively.

SF-36 summary and subscale scores are reliable outcomes of neuropsychiatric events in systemic lupus erythematosus

OBJECTIVE

To examine change in health-related quality of life in association with clinical outcomes of neuropsychiatric events in systemic lupus erythematosus (SLE).

METHODS

An international study evaluated newly diagnosed SLE patients for neuropsychiatric events attributed to SLE and non-SLE causes. The outcome of events was determined by a physician-completed seven-point scale and compared with patient-completed Short Form 36 (SF-36) health survey questionnaires. Statistical analysis used linear mixed-effects regression models with patient-specific random effects.

RESULTS

274 patients (92% female; 68% Caucasian), from a cohort of 1400, had one or more neuropsychiatric event in which the interval between assessments was 12.3 ± 2 months. The overall difference in change between visits in mental component summary (MCS) scores of the SF-36 was significant (p<0.0001) following adjustments for gender, ethnicity, centre and previous score. A consistent improvement in neuropsychiatric status (N=295) was associated with an increase in the mean (SD) adjusted MCS score of 3.66 (0.89) in SF-36 scores. Between paired visits when the neuropsychiatric status consistently deteriorated (N=30), the adjusted MCS score decreased by 4.00 (1.96). For the physical component summary scores the corresponding changes were +1.73 (0.71) and -0.62 (1.58) (p<0.05), respectively. Changes in SF-36 subscales were in the same direction (p<0.05; with the exception of role physical). Sensitivity analyses confirmed these findings. Adjustment for age, education, medications, SLE disease activity, organ damage, disease duration, attribution and characteristics of neuropsychiatric events did not substantially alter the results.

CONCLUSION

Changes in SF-36 summary and subscale scores, in particular those related to mental health, are strongly associated with the clinical outcome of neuropsychiatric events in SLE patients.

Cutaneous lupus erythematosus: clinical and immunological study of 308 patients stratified by gender

BACKGROUND

Numerous studies involving systemic lupus erythematosus (SLE) have attempted to identify gender differences in patients with lupus erythematosus (LE). However, few reports on cutaneous lupus erythematous (CLE) have identified gender differences.

AIM

To analyse and compare the prevalence and characteristics of the main clinical and immunological features of male and female patients with CLE.

METHODS

The medical records of 103 (33.4%) male and 205 (66.6%) female patients with CLE who were treated as inpatients or outpatients between January 1985 and December 2000 were retrospectively studied. All patients were reviewed in detail stratified by a predefined protocol.

RESULTS

Female patients had a higher prevalence of Raynaud's phenomenon (P < 0.01), chilblain lupus (P = 0.005), arthralgias (P = 0.001) and SLE (P < 0.01). Female patients were also more likely to have an increased erythrocyte sedimentation rate (P < 0.005), higher levels of antinuclear antibodies (P < 0.001) and decreased levels of C3 (P < 0.001), C4 (P < 0.01) and CH50 (P < 0.01). There was a higher prevalence of clinical and laboratory abnormalities in female patients who had both SLE and CLE than in male patients with both conditions. Conclusions.  In our series, differences in the expression of CLE existed between male and female patients with respect to the type of lesions, systemic features, and immunological findings.

Bronchiectasis in primary Sjögren's syndrome: prevalence and clinical significance

OBJECTIVES

To analyse the prevalence and clinical significance of bronchiectasis in a large series of patients with primary Sjögren's syndrome (SS) and evaluate its impact on disease expression and outcomes.

METHODS

The study cohort included 507 patients with primary SS. Bronchiectasis were diagnosed according to pulmonary computed tomography (CT). As a control group, we included 37 consecutive SS patients evaluated by pulmonary CT during the same study period without pulmonary involvement.

RESULTS

Fifty primary SS patients had bronchiectasis according to the pulmonary CT. Nine patients were excluded due to non-autoimmune processes and 41 were classified as bronchiectasis associated with primary SS (40 women, mean age of 64 years). All cases of bronchiectasis were of the cylindrical type and were located in the inferior lobes in 29 cases (71%). Patients with bronchiectasis were older at diagnosis of SS (60.39 vs. 52.54 years, p=0.022) and had a higher frequency of hiatus hernia (41% vs. 16%, p=0.024) in comparison with controls. Immunologically, patients with bronchiectasis had a lower frequency of anti-Ro/SS-A antibodies (27% vs. 54%, p=0.022) but a higher frequency of anti-smooth muscle--SMAantibodies (82% vs. 60%, p=0.043). During follow-up, patients with bronchiectasis had a higher frequency of respiratory infections (56% vs. 3%, p<0.001) and pneumonia (29% vs. 3%, p=0.002) in comparison with those without.

CONCLUSIONS

Patients with primary SS and bronchiectasis are characterised by an older age, a high frequency of hiatus hernia, a specific immunologic pattern (low frequency of anti-Ro/SS-A and high frequency of anti-SMA) and during follow-up a much higher frequency of respiratory infections and pneumonia.
