The emerging problem of biological treatment in migrant and travelling populations: it is time to extend guidelines for the screening of infectious diseases.

The use of biological agents in the treatment of rheumatic diseases has been widely associated with an increased risk of reactivation of several latent infections. National and international guidelines recommend screening for infectious diseases before starting these drugs. In Western countries screening is limited to latent tuberculosis infection, HIV and viral hepatitis. However, the increasing globalisation and the remarkable number of migrating and travelling people worldwide make this approach no longer adequate. The Italian and Spanish Societies of Rheumatology and Tropical Medicine wish to issue a warning about the need to improve awareness of doctors about the risk of reactivation of infectious tropical diseases in migrant or travelling patients who undergo biological therapy. Thus, the Italian and Spanish Societies are now planning to issue specific recommendations, based on a multidisciplinary contribution and a systematic review of the literature, for screening and follow-up of active and latent chronic infections in candidate patients for biological agents, taking into account the patient's area of origin and risk of infectious diseases.

Factors related to radiological damage in 61 Spaniards with early rheumatoid arthritis.

OBJECTIVE: To determine whether the presence of radiographic erosions at disease onset in patients with early rheumatoid arthritis (RA) is associated with clinical, serological, or genetic factors of poor outcome and whether patients with erosions only in the feet have a different pattern of presentation. METHODS: Sixty one patients with early RA (<6 months of evolution) were studied. Clinical evaluation and serological, radiological, and genetic studies were performed at disease onset and after one year. RESULTS: Forty one (67%) patients showed erosions in their hands or in their feet, or in both. Subjects with erosive RA had a higher number of swollen joints (SJN; 9 (SD 6) v. 6 (3), p=0.008), and rheumatoid factor (RF) positivity was more common (80% v. 50%, p<0.02) than those without erosions. Seven (17%) of the 41 patients in the group with erosions had erosions only in their feet. This group had a longer duration of morning stiffness (120 (60) v. 72 (52) min, p<0.005), better patient's global assessment of general health (34 (22) v. 57 (25), p< 0.05), and lower erythrocyte sedimentation rate (32 (22) v. 60 (30) mm/1st h, p <0.05) than the rest of the subjects with erosions, and none of them was in remission after one year. Remission after one year was related to a lack of cortical damage at onset and RF negativity. CONCLUSIONS: Radiological damage at disease onset is associated with a worse clinical presentation and RF positivity, which are markers of poor outcome. There is a subgroup of patients, with erosions only in their feet, whose clinical presentation is less aggressive. To identify these cases of early erosive RA, radiographs of the feet should be obtained routinely.

[High prevalence of vitamin D deficiency in postmenopausal women at a rheumatology office in Madrid. Evaluation of 2 vitamin D prescription regimens]. / Alta prevalencia de deficiencia de vitamina D en mujeres posmenopáusicas de una consulta reumatológica en Madrid. Evaluación de dos pautas de prescripción de vitamina D.

BACKGROUND: Vitamin D deficiency has been frequently observed in the elderly population in Europe. However few information is available about the vitamin D status in postmenopausal women in the Mediterranean countries. The aim of this study was to evaluate the vitamin D status assessed by serum 25(OH)D3 (calcidiol) in postmenopausal women who attended a Rheumatology practice in Madrid area, and to evaluate calcidiol serum levels through one year after two forms of vitamin D administration. PATIENTS AND METHODS: Calcidiol serum levels were measured in 171 postmenopausal women (111 with osteoporosis and 60 without osteoporosis). 82 women with calcidiol serum levels < 10 ng/ml were distributed in two groups: Group I received 800 U/day of vitamin D3 associated with calcium (1 g/day) and group II, one dose of 80,000 U vitamin D orally as calcidiol and latter a daily dose of 800 U vitamin D3 plus 1 g calcium. Calcidiol serum levels were measured by RIA in both groups at basal condition and after three, six and twelve months under treatment. RESULTS: Three cut-offs were considered: 10, 15 and 20 ng/ml of calcidiol. Percentages of postmenopausal women with vitamin D deficiency for such cut-offs were: 35.3%, 64.1% and 87.1%, respectively. After three months of treatment, women from group II showed calcidiol serum levels higher than group I. At six and twelve months calcidiol serum levels were similar in both groups. CONCLUSIONS: A high prevalence of vitamin D deficiency was observed in a group of postmenopausal women who attended a rheumatology practice in Madrid area. Both forms of vitamin D administration seem not sufficient to maintain the adequate calcidiol serum levels in postmenopausal deficient women. A dose of 80,000 U of calcidiol twice a year should be considered.

Antiperinuclear factor as a prognostic marker in rheumatoid arthritis.

OBJECTIVE: Antiperinuclear factor (APF) is an autoantibody detected in >50% of patients with rheumatoid arthritis (RA); it shows a specificity of roughly 90%. We investigated the possible role of APF as a prognostic marker in RA. METHODS: A series of 103 patients with RA who fulfilled the 1987 American College of Rheumatology criteria (88 women and 15 men; mean age 55.5 yrs, mean disease duration 9 yrs) were prospectively followed. Sixteen variables were assessed in each patient at inclusion and over a 3 year period. APF was determined by indirect immunofluorescence assay using human buccal mucosal cells as substrate. APF assays were done at entry and at the end of followup without knowledge of the clinical status of the patients. Mann-Whitney U, chi-squared tests, variance analysis, and kappa index were used for statistical analysis. RESULTS: Eighty of 103 patients completed followup. APF was detected in 40 of 80. At inclusion, APF correlated with the visual analog scale (VAS) of pain (p = 0.02). However, patients who showed APF positivity at entry had a less favorable course than APF negative individuals, as shown by a worse VAS of well being (p = 0.01), Ritchie index (p = 0.01), number of painful joints (p = 0.03), grip strength (p = 0.01), C-reactive protein (p = 0.04), and Health Assessment Questionnaire score (p = 0.03) at the end of the study. In addition, APF positive patients showed a worse radiological course (p = 0.03). CONCLUSION: Our results suggest APF is a possible marker of poor prognosis in RA.
