Development of new extra-glandular manifestations or associated auto-immune diseases after establishing the diagnosis of primary Sjögren's syndrome : A long-term study of the Antonius Nieuwegein Sjögren (ANS) cohort.

To investigate in a long-term study, the development of new extra-glandular manifestations (EGM) or associated auto-immune diseases (AID) from 1 year after establishing the diagnosis of primary Sjögren's syndrome (pSS). The primary goal was to examine the frequency and type of these manifestations and to find out which demographic, clinical and serological profile was most at risk. All outpatients diagnosed with primary Sjögren's syndrome were included in a retrospective study, with at least one check-up per year, from June 1991 until August 2015. Patients also fulfilling the criteria for concomitant connective tissue disorders were excluded. Data were collected with respect to the cumulative prevalence of a new EGM or associated AID. 140 patients were included in the final analysis. After 10 years of follow-up, the cumulative incidence of a new EGM or associated AID was 30.7%. The most frequent events were polyneuropathy, interstitial lung disease, (poly)arthritis, discoid lupus erythematosus (LE)/subacute cutaneous LE and Hashimoto's disease. Non-Hodgkin lymphoma was not diagnosed during the follow-up. Patients without chronic benign pain syndrome (CBP) (HR 2.13; 95% CI [0.94-4.76]; p = 0.061), but in particular those with cryoglobulins (HR 2.87; 95% CI [1.20-6.86]; p = 0.013), developed more events. Age at diagnosis, gender, the presence of ANA, anti-Ro/SSA, anti-La/SSB, IgM-RF, decreased levels of C3 or C4, or hypergammaglobulinaemia did not show any statistically significant differences. The burden of disease in pSS is higher than expected due to the development of EGM or associated AID. Therefore, we recommend long-term follow-up of all pSS patients, particularly those with cryoglobulinaemia.

Polyarthritis in primary Sjögren's syndrome represents a distinct subset with less pronounced B cell proliferation a Dutch cohort with long-term follow-up.

The primary goal was to investigate the differences in patients with and without polyarthritis (PA) in primary Sjögren's syndrome (pSS) in a clinical-based (real-life) setting, with respect to demographic characteristics, cumulative prevalence of other extra-glandular manifestations (EGM), hypergammaglobulinaemia and serological profile. The secondary goal was to describe the characteristics of polyarthritis in our pSS cohort. Patients diagnosed with pSS and polyarthritis but without rheumatoid arthritis (RA)-like changes on X-rays were followed up prospectively from June 1991 until August 2014, with at least one check-up each year. Patients fulfilling the criteria for concomitant connective tissue disorders were excluded. Data were collected with respect to the prevalence of systemic auto-antibodies (anti-nuclear antibodies (ANA), anti-Sjögren's syndrome-related antigen A (anti-SSA), anti-Sjögren's syndrome type B (anti-SSB) and immunoglobulin M-rheumatoid factor (IgM-RF)) and other EGM related to pSS. A total of 134 patients were included for the final analysis. The median follow-up was 86 months (range 0-368 months). Twenty-two patients (16.4 %) had polyarthritis. The prevalence of systemic auto-antibodies including rheumatoid factor did not differ between the two groups. Anti-cyclic citrullinated peptide (CCP) occurred much more frequently in the polyarthritis-positive (PA+) patients (13.7 vs 0.9 %; p = 0.015). Hypergammaglobulinaemia (p = 0.002) and increased levels of IgG (p = 0.013) occurred much less frequently in the PA+ group compared to the polyarthritis-negative (PA-) group. The mean total number of EGM or of any specific EGM did not differ between the two groups. Most patients had a mild, symmetrical PA predominantly involving the finger joints (proximal interphalangeal joints/metacarpophalangeal joints (PIP/MCP)) and/or wrists and/or metatarsophalangeal (MTP) joints. Significant morning stiffness lasting ≥1 h was found infrequently (32 %). All patients were treated with a classic (c) disease-modifying antirheumatic drug (DMARD), but in two cases, treatment was necessary with a tumour necrosis factor (TNF) inhibitor. PA+ pSS patients are more frequently anti-CCP positive and have a less pronounced B cell proliferation than PA- patients. PSS patients with PA seem to have a relatively mild articular expression with a favourable course.

Spontaneous ankylosis in erosive osteoarthritis of the finger joints: a case series of eight postmenopausal women.

Osteoarthritis of the hands is very common, particularly in elderly people. Little is known though, is the subset of erosive osteoarthritis (EOA), which predicts a poorer prognosis and causes much more discomfort. Even less known is the fact that this subset can evolve into spontaneous ankylosis. We describe eight women (average age 62.6, range 54-74 years) with EOA and spontaneous ankylosis of the proximal interphalangeal (PIP) and/or distal interphalangeal (DIP) joints. In total, 21 PIP joints (0-7 per patient) were found with EOA and nine PIP joints (0-3 per patient) with ankylosis. In one patient, ankylosis of the PIP was already seen at the first presentation. In the other cases, it took an average of 77.4 months (range 34-119) for EOA to develop into ankylosis of the PIP. For DIP joints, the numbers were 17 joints (1-4 per patient) with EOA and three joints (0-1 per patient) with ankylosis, respectively. In one patient, ankylosis of the DIP was already seen at the first presentation. Ankylosis was found significantly more often on the left hand (n = 10) compared to the right hand (n = 2; p < 0.0005), while all the patients were right handed. No difference in handedness was found for the occurrence of EOA. Although rare, PIP or DIP joint with EOA can-over the course of several painful years-develop into a spontaneous pain-free ankylosis. Ankylosis was more commonly found in the left hand than in the right hand, probably due right handedness.

Lower prevalence of extra-glandular manifestations and anti-SSB antibodies in patients with primary Sjögren's syndrome and widespread pain: evidence for a relatively benign subset.

OBJECTIVES: To investigate in primary Sjögren's syndrome, the differences between patients with and without widespread pain (WSP) with respect to the cumulative prevalence of extra-glandular manifestations (EGMs) and systemic auto-antibodies. METHODS: All outpatients diagnosed with primary Sjögren's syndrome (2) were included in a prospective follow-up, with at least one check up each year, from June 1991 until November 2011. Patients who also fulfilled criteria for concomitant connective tissue disorders were excluded. Widespread pain was defined as the presence of long-lasting (>one year) diffuse pain in all four body quadrants. Data were collected with respect to the cumulative prevalence of systemic auto-antibodies (anti-nuclear antibodies [ANA], anti-Sjögren syndrome A antigen [anti-SSA], anti-Sjögren syndrome B antigen [anti-SSB] and immunoglobulin M-Rheumatoid factor [IgM-RF]) and EGMs related to primary Sjögren's syndrome. RESULTS: Eighty-three patients were included in the final analysis. Thirty-nine (34.9%) patients had widespread pain. Anti-SSB was found less frequently (p<0.05) in patients with WSP than in patients without WSP. The WSP-positive patients were more frequently negative for all four tested autoantibodies (p<0.05). The patients with WSP had fewer EGMs than the patients without WSP (p<0.01); more specifically, polyneuropathy occurred less frequently (p<0.05) in the patients with WSP. Cytopenia, uveitis, pericarditis, pleuritis, interstitial lung disease, vasculitis, monoclonal gammapathy of unknown significance and non-Hodgkin lymphoma only occurred in the patients without WSP. CONCLUSIONS: Primary Sjögren's patients with WSP form a benign subgroup, with a lower prevalence of anti-SSB and EGMs (in particular polyneuropathy). We suggest a shorter period of follow-up for this subset than for the WSP-negative patients.

Rituximab in life threatening antisynthetase syndrome.

This case study reports a patient with severe interstitial pneumonitis, mild polyarthritis and polymyositis, accompanied by the presence of anti-Jo-1 antibodies diagnosed as antisynthetase syndrome. The concurrence of anti-Jo-1 with anti-Ro/SSA antibodies leads to a more severe form of interstitial lung disease. This patient was referred to our hospital because of life threatening respiratory failure. He was refractory to glucocorticoids and cyclophosphamide, but was successfully treated with two sequential infusions of rituximab. Clinical condition improved very rapidly. Response to treatment was well correlated with a fall of levels of serum soluble IL2-receptor. A decrease in pulmonary disease activity was visualized on PET-scans before and after two sequential rituximab infusions.

Monoarthritis of the elbow due to metastatic colon carcinoma: diagnosis based on the presence of adenocarcinoma cells in synovial fluid.

There are many diseases that can cause monoarthritis, malignancy being one of the more rare causes. We present such a case and discuss the relationship between malignancy and arthritis. Typically a large joint is involved, most frequently the knee and very rarely the elbow. The value of cytological examination of synovial fluid is stressed. Synovial fluid in malignant joint disease is usually sanguineous and not consistent with an inflammatory process. Synovial fluid analysis can avoid a biopsy of bone or synovium and lead to an early diagnosis and palliative treatment.

Nocardiosis: a case series and a mini review of clinical and microbiological features.

Infections caused by Nocardia species are uncommon and have a wide variety of clinical manifestations in immunocompetent and immunocompromised patients. The diagnosis of nocardiosis can easily be missed because there are no characteristic symptoms. We present one case of a Nocardia infection in detail and give a brief description of eight other cases, including a relatively unique type of Nocardia veterana, diagnosed in our hospital during a five-year period. The diversity of clinical manifestations, microbiological identification and general principles of treatment of nocardiosis are reviewed.

Extremely high serum ferritin levels as diagnostic tool in adult-onset Still's disease.

The diagnosis of adult-onset Still's disease (ASD) is difficult to establish due to the nonspecific clinical and laboratory findings. A markedly raised serum ferritin level is a typical finding, although it is not well understood why ferritin levels are extremely high in ASD. We discuss several possible explanations leading to the extremely high levels of ferritin.

Intensive treatment with methotrexate in early rheumatoid arthritis: aiming for remission. Computer Assisted Management in Early Rheumatoid Arthritis (CAMERA, an open-label strategy trial).

BACKGROUND: To investigate whether intensive treatment with methotrexate (MTX) according to a strict protocol and a computerised decision program is more beneficial compared to conventional treatment with MTX in early rheumatoid arthritis. METHODS: In a two-year multicentre open label strategy trial, 299 patients with early rheumatoid arthritis were randomly assigned to the intensive strategy group or the conventional strategy group. Patients in both groups received MTX, the aim of treatment being remission. Patients in the intensive treatment group came to the outpatient clinic once every month; adjustment of the MTX dosage was tailored to the individual patient on the basis of predefined response criteria, using a computerised decision program. Patients of the conventional strategy group came to the outpatient clinic once every three months; they were treated according to common practice. Cyclosporine was added if patients had an inadequate response to maximal tolerated MTX doses. RESULTS: Seventy six (50%) patients in the intensive strategy group achieved at least one period of remission during the two year trial, versus 55 patients (37%) in the conventional strategy group (p = 0.03). Areas under the curve for nearly all clinical variables were significantly lower-that is, there was a better clinical effect for the intensive treatment group compared with the conventional treatment group. CONCLUSION: The results of this study show that it is possible to substantially enhance the clinical efficacy early in the course of the disease by intensifying treatment with MTX, aiming for remission, tailored to the individual patient. Furthermore, participating rheumatologists indicated that the computerised decision program could be a helpful tool in their daily clinical practice.

Relationship between histological subtypes and clinical characteristics at presentation and outcome in biopsy-proven temporal arteritis. Identification of a relatively benign subgroup.

Temporal arteritis (TA) may offer major complications, whilst high dosage of prednisone may result in serious side effects. We tried to identify a subgroup of TA, which can be treated with a lower dosage of prednisone. Retrospectively, clinical and laboratory data were studied at presentation, as well as the outcome in 44 consecutive patients with biopsy-proven temporal arteritis. These data were related to three particular histological subgroups, (a) classical giant cell arteritis, (b) atypical arteritis, and (c) 'healed arteritis', defined according to Allsop and Gallagher (The American Journal of Surgical Pathology 5:317-332, 1981). At presentation in subgroup c, erythrocyte sedimentation rate was lower and the level of haemoglobin was higher than in the other two subgroups. During follow-up in the healed arteritis group, reactivation, recurrence, or early death were not observed, whilst prednisone dosage after 2 and 3 years was lower compared to subgroup b. Major complications (permanent blindness and cerebrovascular accident) were only observed in subgroups a and b. We believe that the healed arteritis subgroup represents a relatively benign subgroup with a mild clinical presentation and a good prognosis. Therefore, a much lower initial prednisone dosage (15 mg/day) is suggested for patients in subgroup c than in the other two subgroups (40-60 mg/day).

Joint surgery in the Utrecht Rheumatoid Arthritis Cohort: the effect of treatment strategy.

OBJECTIVE: To investigate the prevalence and prognostic factors of joint surgery in a large cohort of patients with rheumatoid arthritis, whose treatment, clinical and radiographic data have been assessed at predefined points in time since disease onset. METHODS: Data on surgical interventions were retrospectively obtained from 482 patients with rheumatoid arthritis whose follow-up data for at least 2 years were available, including treatment and response to treatment during the first 2 years. Survival time until the first surgical intervention and until the first major surgical intervention was determined for the total study population by Kaplan-Meier survival curves. Three separate Cox regression analyses were carried out to determine which variables measured at baseline, during the first year and during the first 2 years were predictors for joint surgery. RESULTS: 27% of the patients underwent surgical interventions. Mean survival time until the first surgical intervention was 10.4 years. The percentage of patients with a surgical intervention was 10% lower in the group with response to treatment when compared with the non-response group. Next to a delayed start with disease-modifying antirheumatic drugs, fast radiographic progression during the first year and first 2 years was a predictor of joint surgery in the multivariate regression analyses. CONCLUSION: Treatment with disease-modifying antirheumatic drugs immediately after diagnosis results in less joint surgery when compared with a delayed start. Furthermore, joint surgery is carried out more often in patients who do not respond to treatment.

[Favourable effect of lacrimal plugs after 3 and 9 months in 20 patients with severe sicca syndrome]. / Gunstig effect van traanbuispluggen bij 20 patiënten met ernstig siccasyndroom na 3 en na 9 maanden.

OBJECTIVE: To describe the results of the insertion of lacrimal plugs in patients with severe symptoms of dry eyes. DESIGN: Prospective descriptive study. METHOD: 20 patients who had severe symptoms of dry eyes despite topical therapy were included. The diagnoses were: 'primary Sjögren's syndrome' (n = 10), 'probably a primary Sjögren's syndrome' (n = 5) and 'secondary Sjögren's syndrome' (n = 5). Following a favourable subjective reaction to resorbable plugs, a non-resorbable silicone plus was inserted bilaterally into the openings of the inferior lacrimal ducts. During follow-up, the effect of treatment was assessed by means of various measurements of function of the lacrimal glands. RESULTS: After 3 and 9 months there was a measurable favourable effect with regard to tear production (Schirmer-test), tear film stability ('tear film break-up time'), the damage to the cornea (Bengal-red-test) and the subjective symptoms of dry eye on a visual analogue scale (VAS). The difference in comparison with the initial values was significant except for the Bengal-red-test after 9 months. There were no complications. In the 5 patients with a basal Schirmer test value of o mm after 5 min, there was no improvement.

Treatment of primary Sjögren's syndrome with D-penicillamine: a pilot study.

BACKGROUND: Up to now no satisfying systemic treatment is available for patients with primary Sjögren's syndrome. METHODS: In a prospective, open study we investigated the effect of D-penicillamine (first three months 250 mg/day, next three months 500 mg/day) on clinical and immunological parameters in 19 patients with primary Sjögren's syndrome and a mean disease duration of 3.8 years. RESULTS: Eight patients had to stop treatment mainly due to severe (reversible) loss of taste. Clinically, a statistically significant increase in basal salivary flow was observed after three months (p<0.05). In addition, improvement was noted in the Schirmer test and stimulated parotid salivary flow after six months, but these differences were not statistically significant. Laboratory values showed a decrease in ESR (p<0.05) and levels of IgA and IgM (both p<0.02) after six months, a decrease in levels of IgA-Rf and IgM-Rf after three months (both p<0.05), and an increase in haemoglobin level (p<0.05). CONCLUSION: From this pilot study we conclude that the treatment of primary Sjögren's syndrome with D-penicillamine has only marginal beneficial effects. Together with its clear side effects this means that D-penicillamine is unsuitable for this indication.

Prevalence of vertebral deformities and symptomatic vertebral fractures in corticosteroid treated patients with rheumatoid arthritis.

OBJECTIVE: This study was designed to determine whether the prevalence of vertebral deformities in patients with rheumatoid arthritis (RA) treated with corticosteroids (Cs) is higher than in RA patients not receiving Cs therapy. PATIENTS AND METHODS: This multicentre cross-sectional study included 205 patients with RA who were receiving Cs orally on a daily basis and 205 patients with RA who did not receive Cs, matched for sex and age. Vertebral deformities were scored according to the Kleerekoper method. RESULTS: Vertebral deformities were found in 52 (25%) patients on Cs and in 26 (13%) patients not on Cs. Sixteen (8%) patients in the group on Cs had experienced clinical manifestations of an acute vertebral fracture in the past vs only three patients (1.5%) among those not on Cs. The use of Cs tended to increase the risk of developing a vertebral deformity [adjusted odds ratio (OR) 1.56, 95% confidence interval (CI) 0.81-2.99] and symptomatic vertebral fracture (adjusted OR 1.42, 95% CI 0.24-8.32). Each 1-mg increase in the current daily Cs dose increased the risk of a vertebral deformity (adjusted OR 1.05, 95% CI 0.98-1.13) and of a symptomatic vertebral fracture (adjusted OR 1.05, 95% CI 0.89-1.24). CONCLUSION: There is a higher prevalence of vertebral deformities and clinical manifestations of vertebral fractures in patients on Cs than in those not on Cs. Our data indicate that the use of Cs and each 1-mg increase in the current daily Cs dose may increase the risk of development of a vertebral deformity and symptomatic vertebral fracture in patients with RA.
