Validation of an Italian version of the Fibromyalgia Impact Questionnaire (FIQ-I).

OBJECTIVE: To validate a translated Italian version of the Fibromyalgia Impact Questionnaire (FIQ). METHODS: The Italian version of the FIQ was administered to 50 patients affected by fibromyalgia (FM) (48 patients filled out the questionnaire again 10 days later) together with the Italian version of the Stanford Health Assessment Questionnaire (HAQ), the Medical Outcomes Survey Short Form-36 (SF-36), and a tender point count (TPC) obtained by summing the score (0-3) of each tender point tested by thumb palpation. All patients were asked about the severity of pain today (10 cm visual analog scale) and the duration of symptoms. Test-retest reliability was assessed using Spearman correlations. Internal consistency was evaluated with Cronbach's alpha of reliability. Construct validity of the FIQ was evaluated by correlations between the HAQ and subscales of the SF-36 as well as the TPC. RESULTS: The mean duration of symptoms was 6.5 years and the mean age of the participants was 57.4 years. Test-retest reliability was between 0.74 and 0.95 for physical functioning as well as for the total FIQ and other components. Internal consistency was 0.90 for the overall FIQ. Significant correlations were obtained between the FIQ items, the HAQ and the SF-36. CONCLUSIONS: The Italian FIQ is a reliable and valid instrument for detecting and measuring functional disability and health status in Italian patients with FM.

Radiographic progression in early rheumatoid arthritis: a 12-month randomized controlled study comparing the combination of cyclosporin and methotrexate with methotrexate alone.

OBJECTIVE: To determine whether patients with early rheumatoid arthritis (RA) treated with cyclosporin A (CsA) and methotrexate (MTX) in combination for 12 months show a lower rate of radiographic deterioration than those treated with MTX alone. METHODS: In this controlled and randomized single-blind trial, 61 consecutive patients with untreated RA of less than 2 yr duration were treated with either CsA + MTX combination therapy (n = 30) or MTX alone (n = 31). The primary end-point was radiographic progression after 12 months, measured using the damage score (DS) of the Sharp and van der Heijde method. RESULTS: Although there was a significant difference between the mean baseline and 12-month DS in both treatment groups (MTX/CsA, 1.93 +/- 0.90; MTX, 7.47 +/- 2.03), it was significantly less in the combination arm (P = 0.018). Of the 30 evaluable CsA + MTX patients, 16 (53%) were ACR20 responders, 15 (50%) ACR50 and 14 (47%) ACR70; the corresponding figures in the MTX arm were 19 (61%), 13 (44%) and 6 (19%). Toxicity was acceptable in both groups. CONCLUSIONS: In patients with early RA, CsA + MTX combination therapy led to a significantly lower rate of 12-month radiographic progression, was effective on inflammatory articular symptoms, and was well tolerated.

Hypersomnolence in fibromyalgia syndrome.

OBJECTIVE: To evaluate hypersomnolence in patients affected by fibromyalgia syndrome. METHODS: Thirty consecutive patients affected by fibromyalgia syndrome (FMS) (28 F) completed a sleep questionnaire and underwent the following evaluations: lung function tests; polysomnography; the Epworth sleepiness scale (ESS), which measures sleep complaints and daytime hypersomnolence; and the visual analogical scale (VAS) to detect subjective pain, fatigue, anxiety and depression. RESULTS: The FMS patients were divided into two groups based on their ESS score. Patients complaining of daytime hypersomnolence had a higher number of tender points (15 +/- 2 vs. 12 +/- 1, p < 0.01), a higher subjective pain score (72 +/- 15 vs. 52 +/- 13, p < 0.05), and more fatigue (p < 0.05). The diffusing capacity of the lung (Tlco) was more impaired and the occurrence of periodic breathing was higher. FMS patients complaining of daytime somnolence had significantly less efficient sleep than the FMS patients with no daytime somnolence (p < 0.05), i.e. a lower proportion of stage 3 sleep (5 +/- 2% vs. 12 +/- 3%; p < 0.001), stage 4 sleep (1 +/- 0.5% vs. 4 +/- 1%; p < 0.001), and twice as many arousals per hour of sleep (p < 0.01). The respiratory pattern of FMS patients with hypersomnolence showed a higher occurrence of periodic breathing (p < 0.05). The short length of apneas and hypopnoeas did not affect the apnea/hypopnea index (5.1 +/- 3 vs. 7 +/- 4; ns), but FMS patients with daytime hypersomnolence had a greater number of desaturations per hour of sleep (11 +/- 6 vs. 6 +/- 5; p < 0.05). Pulmonary volumes did not differ between the two groups. The EES score was significantly correlated in FMS patients, and even more markedly in the FMS patients with hypersomnolence, TLco, A/I, and disease duration. The ESS score was correlated significantly with the number of tender points only in FMS patients with daytime hypersomnolence. CONCLUSION: The occurrence of daytime hypersomnolence in FMS patients is linked to a greater severity of fibromyalgia symptoms and to more severe polysomnographic alterations.

[Case report: rheumatoid arthritis and large granular lymphocytes syndrome]. / Artrite reumatoide e leucemia a "large granular lymphocytes": descrizione di un caso clinico.

Felty's syndrome (FS) is a rare complication (less than 1%) of rheumatoid arthritis (RA), with the clinical feature of splenomegaly and neutropenia. Approximately 10-40% of FS patients have an expansion of peripheral blood large granular lymphocytes (LGL). This cell population mainly consists of two subsets: cytotoxic T cells (CD8+, CD57+) and natural killer cells (CD3-,CD8-,CD56+). It has been hypothesised that LGL expansion could be responsible for neutropenia by suppressing neutrophil precursors in the bone marrow, but various mechanisms have been proposed to explain this association. We report a case of a 60-year-old woman with rheumatoid factor positive RA who developed LGL expansion responsible for splenomegaly, but without neutropenia. In conclusion, LGL expansion is an uncommon complication of RA and may be responsible for both FS and clinical pictures resembling FS.

The role of NSAIDs in psoriatic arthritis: evidence from a controlled study with nimesulide.

OBJECTIVE: To define the optimal dose of nimesulide (NIM) for treating psoriatic arthritis. METHODS: Eighty patients entered a 4-week, double-dummy, randomised, controlled study. Each patient was allocated to one of the following treatment groups: NIM 100 mg/day, NIM 200 mg/day, NIM 400 mg/day, or placebo. Primary end points for arthritis assessment were the scores for tender and swollen joints, and the physician's and patient's global assessment of efficacy. RESULTS: 76/80 patients completed the study. NIM decreased the score for tender and swollen joints from baseline to the end swollen joints from baseline to the end of therapy (p < 0.05). Pain severity on a visual analogue scale (VAS) was reduced by NIM 200 mg (p = 0.03) or NIM 400 mg (p = 0.019) compared to placebo, as was morning stiffness (p = 0.038 and p = 0.008, respectively), but the trends with 100 mg were not statistically significant. The investigators and patients assessed the global efficacy of the NIM 200 and 400 mg/day groups as better than placebo or NIM 100 mg. Side effects were observed in 12 patients (15%) during treatment. They were mostly mild, only one patient withdrew from the study as a result, and the trend for a higher incidence with NIM was not statistically significant. The Psoriasis Area Severity Index (PASI) and the ESR did not show any significant changes. Patients in the placebo group took more paracetamol per day compared with those in the NIM groups (p = 0.007). CONCLUSIONS: Nimesulide 200 and 400 mg/day are effective and safe in psoriatic arthritis.

Diet therapy for rheumatoid arthritis. A controlled double-blind study of two different dietary regimens.

OBJECTIVE: To evaluate the effects of a diet therapy in patients with rheumatoid arthritis (RA). METHODS: Fifty RA patients entered a 24-week double-blind, randomised, controlled-study of two different dietary regimens (an experimental diet high in unsaturated fats, low in saturated fats with hypoallergenic foods vs. a control well-balanced diet). The primary end points of the study were 20% and 50% improvement in disease activity according to composite symptoms (Paulus index) of arthritis. Other end points were the other measures of disease activity at 12 and 24 weeks of diet treatment. RESULTS: The 2 groups were comparable at inclusion. Diet treatment was well tolerated and the rate of drop-outs was low. Percentage of patients with global 20 or 50% response didn't differ between experimental and control group after the 24-week of diet treatment. The experimental diet group did better for all the variables considered but only four variables (Ritchie's index, tender and swollen joints, and ESR) reached a statistical difference by multivariate analysis. Adjusting these data for weight variations, the number of tender joints (p=0.014) and ESR (p=0.025) were still statistically significant. CONCLUSIONS: Dietary manipulation, either by modifying food supplements or by reducing weight, may give some clinical benefit although no significant improvement can be observed assessing the results with a composite index.

Oral type II collagen in the treatment of rheumatoid arthritis. A six-month double blind placebo-controlled study.

OBJECTIVE: To evaluate the efficacy of oral chicken type II collagen (CII) in the treatment of rheumatoid arthritis (RA). METHODS: Sixty patients with clinically active RA of long duration (mean 7.2 +/- 5.5 years) were treated for 6 months with oral chicken CII at 0.25 mg/day (n = 31) or with placebo (n = 29) in a double-blind randomized study. RESULTS: The response rate to treatment of the collagen-treated group, based on the ACR 20% criteria, was higher than that of the control group but this difference was not statistically significant at any time. Intention-to-treat (ITT) analysis did not show statistically significant improvement in any of the several secondary outcome measures over the 6 months of the study in the collagen-treated patients in comparison with the placebo-treated group. However, in 2 collagen-treated patients we observed a clinical remission according to the criteria of the American Rheumatism Association. CONCLUSION: Our study seems to show that the oral treatment of RA patients with chicken CII is ineffective and results in only small and inconsistent benefits. Furthermore, our results raise the possibility that in a sub-group of patients oral collagen administration, usually considered devoid of harmful effects, may actually induce disease flares.

Lamotrigine-induced lupus.

A 57-year-old woman was under treatment for epilepsy with lamotrigine 2 mg/kg/d since 1996. In April 1998 she was admitted to the Rheumatology Unit for arthralgias affecting the small joints of the hands, wrists and knees, erythematosus skin rash and myalgias. She referred a vascular abnormality at the hands exposed to cold, compatible with Raynaud's phenomenon. Serum antinuclear antibodies (ANA) were positive (1:320, speckled pattern); moreover, a positivity for anti-Ro/SSA was observed. Rheumatoid factor was negative, serum complement was normal. LAC and anticardiolipin antibodies were negative. Drug-related lupus diagnosis was made with resolution of symptoms and gradual normalisation of positivity of ANA and anti-Ro/SSA upon lamotrigine withdrawal. To our knowledge, this is the first case report of an association between lamotrigine and the onset of SLE (systemic lupus erythematosus).
