Hand bone densitometry in rheumatoid arthritis, a five year longitudinal study: an outcome measure and a prognostic marker.

OBJECTIVE: To investigate whether hand bone mineral content (BMC) measurement is an outcome measure for RA and whether the early changes in hand BMC predict functional disability. METHODS: Tender and swollen joints in hands and body, HAQ score, Larsen score on hand radiographs, serum CRP, and hand BMC measurement by DXA were studied every six months for five years in 40 patients with early RA. At the final visit, patients completed the SF-36 and Duruoz hand function questionnaires. RESULTS: All patients completed two years and 29 completed five years' follow up. Hand BMC worsened over the first three years (percentage loss from baseline: mean (SD) -5.5 (7.2), -7.5 (8.4), -9.8 (9.4)) and stabilised over last two years (-9.9 (8.8), -10 (7.8)). Baseline disease activity and function correlated with hand BMC loss at five years (swollen joints in hands: r=-0.38, p=0.043; swollen joints in body: r=-0.47, p=0.01; HAQ: r=-0.52, p=0.004). Percentage change in hand BMC over five years correlated with SF-36 physical function (r=0.61, p<0.01), hand function (r=-0.64, p<0.01), HAQ score (r=-0.63, p<0.01) at five years. Relative risk of bad hand functional outcome at five years was significantly higher for patients with hand BMC loss of >/=1.17 g (smallest detectable difference) than for patients with less bone loss within the first six months (OR=6.9, 95% CI 1.3 to 34.5, p<0.02). CONCLUSION: Early loss of hand BMC in patients with RA is a composite marker of disease activity and functional status and can predict poor functional outcome.

Bone changes in early rheumatoid arthritis.

Bone disease in rheumatoid arthritis affects the peri-articular and axial skeleton and is a major cause of disability. Recent studies have shown that pro-inflammatory cytokines stimulate the expression of osteoprotegerin ligand, a transmembrane protein of the tumour necrosis factor ligand superfamily, on synoviocytes and activated T cells. Osteoprotegerin ligand stimulates osteoclast formation and activation, membrane-bound and soluble osteoprotegerin ligand leading to osteoporosis as well as erosions. Bone densitometry using dual energy X-ray absorptiometry is an objective and precise method for monitoring this bone disease. Bone loss is more rapid in patients with early rheumatoid arthritis and correlates well with measures of inflammation and function. Data are emerging that monitoring bone loss of the hands in early rheumatoid arthritis could be an outcome measure and a prognostic indicator of future functional disability. Suppressing inflammation effectively and the use of bone active agents can reduce the rate of loss. In animal models, osteoprotegerin-a decoy receptor of osteoprotegerin ligand-blocks osteoporosis and erosions without affecting inflammation. The use of new biological agents could in future effectively prevent and treat rheumatoid bone disease.

Longitudinal involvement of the spinal cord in a patient with lupus related transverse myelitis.

Transverse myelitis is a rare and serious complication of systemic lupus erythematosus (SLE). Magnetic resonance imaging is the investigation of choice for diagnosis and followup. This typically shows T1 and T2 signal prolongation, cord widening, and contrast enhancement over several spinal segments. We describe a 21-year-old woman with SLE who developed very extensive SLE related transverse myelitis with longitudinal involvement of the spinal cord from C3 to T2 and from T7 to the conus medullaris. Clinically, this was manifest as leg weakness, bladder dysfunction, severe low back pain, and patchy lower limb sensory loss. She responded to treatment with pulse cyclophosphamide and high dose corticosteroids with complete recovery in 3 months. To our knowledge, this is the first case report of such an extensive "longitudinal" myelitis.

Bone mass measurement and bone metabolism in rheumatoid arthritis: a review.

The involvement of bone in rheumatoid arthritis (RA) is well recognized, and hand bone densitometry appears to be a promising new technique to monitor disease progression by assessing serial changes in hand bone mass in patients with RA. New biochemical markers of bone formation (i.e. osteocalcin) show contradictory results in different studies, although markers of bone resorption (i.e. urinary collagen cross-links) have shown significant increase in patients with RA. Bone histomorphometric studies suggest that the periarticular osteopenia in RA could be related to increased bone turnover locally, whereas generalized osteoporosis could be due to a global negative remodelling balance. The important factors implicated in the pathogenesis of the bone loss are circulating cytokines [e.g. tumour necrosis factor alpha (TNF alpha), interleukin (IL) 1 and IL6] produced by the inflammatory process, use of oral corticosteroids (in the dose of > or = 5 mg) and reduced mobility due to functional impairment. Apart from this underlying osteoporosis, patients with RA have an increased risk of falls secondary to functional impairment and there is an increased risk of fractures in patients with RA. Very few studies are presently available looking at the therapeutic measures to prevent osteoporosis in RA. Future drug trials on the treatment of RA should include bone mass measurement, especially of the hand, as one of the outcome measures.

Longitudinal study of hand bone densitometry in rheumatoid arthritis.

OBJECTIVE: To measure hand bone mineral content (BMC) by dual x-ray absorptiometry and to seek clinical correlates in patients with rheumatoid arthritis (RA), in a prospective, longitudinal study. METHODS: Eighty-one patients with non-steroid-treated RA were assessed at baseline and at month 12, for hand BMC and for disease activity and severity. Hand BMC in patients was compared with that in a control group of 95 normal volunteers, and rate of loss was compared with that in 37 controls. RESULTS: At the initial assessment, male and female patients with RA had lower hand BMC than controls, after correction for age, height, and weight (mean reduction 7.5% in men [P = 0.003] and 7.8% in women [P = 0.01]). After 1 year, there was a further loss of hand BMC in patients (median loss 3.25% in men [P = 0.001] and 1.46% in women [P = 0.05]), but normal controls did not have significant changes in their hand BMC. In patients with disease duration of < 2 years at study entry, the parameters of disease activity improved over 1 year, but they lost significant amounts of hand BMC. Hand BMC loss correlated with baseline C-reactive protein levels. In those with RA of > 2 years duration at entry, the Health Assessment Questionnaire scores and Larsen scores had worsened after 1 year, but there was no significant loss of hand BMC. CONCLUSION: Patients with RA had low hand BMC compared with normal controls, even within 2 years of disease onset. The rate of loss was highest in patients with early disease and correlated with measures of initial disease activity. This loss continued despite clinical improvement.

Fluid retention syndrome and fibromyalgia.

Fluid retention syndrome (FRS) or idiopathic oedema is an unusual clinical entity almost exclusively seen in women, which remains under-diagnosed and poorly understood. It can produce a variety of symptoms ranging from headaches and blurring of vision to abdominal pains and diarrhoea [1]. More commonly it presents with symptoms of bloating, fatigue and generalized weakness. We describe four cases of FRS who presented to the rheumatology clinic with signs and symptoms of fibromyalgia. We also discuss the common features of these two conditions and argue that rheumatologists need to be aware of this condition.

Measurement of hand bone mineral content by dual energy x-ray absorptiometry: development of the method, and its application in normal volunteers and in patients with rheumatoid arthritis.

OBJECTIVES--To develop a method of measuring hand bone mineral content (BMC) by dual energy x ray absorptiometry (DXA); to apply this method of measuring hand BMC to normal volunteers to ascertain causes of variability; and to measure hand BMC in patients with rheumatoid arthritis (RA) of varying duration and severity. METHODS--The x ray beam of the Hologic QDR 1000 dual energy x ray absorptiometer was hardened by introducing a perspex-aluminium plate and the analysis software altered to allow for the small tissue bulk of the hand compared with the torso. Ninety five volunteers (46 men age 24-81 and 49 women age 20-83) had scans of both hands. Eight volunteers were assessed repeatedly to establish reproducibility and effect of hand position. Fifty six patients (22 men, 34 women, age range 25-86 years) with RA of differing duration and severity, had hand BMC measurement by DXA. RESULTS--The precision of BMC measurement was 2.3% with no additional variation due to hand position. Hand dominance had no significant effect on BMC. In men, hand BMC correlated with height (r = 0.57, p < 0.0001), weight (r = 0.58, p < 0.0001), forearm span (r = 0.5, p = 0.0006) and hand volume (r = 0.66, p < 0.0001). In women hand BMC correlated with height (r = 0.66, p < 0.0001), weight (r = 0.4, p = 0.003), forearm span (r = 0.3, p = 0.03) and hand volume (r = 0.49, p = 0.0008). After correcting for all these variables, male volunteers had significantly higher hand BMC than female volunteers (p = 0.01) and patients with RA had lower hand BMC than normal volunteers (total hand BMC in male volunteers 90.9 gms, 95% CI 86.9-95, in male patients 81.7 gms, 95% CI 73.7-89.6, p < 0.004, total hand BMC in female volunteers 62.2 gms 95% CI 59.8-64.5, female patients 52.3 gms, 95% CI 48.1-56.5, p < 0.005). In patients with RA, the hand BMC showed an inverse correlation with age (r = -0.44, p = 0.01), disease duration (r = -0.62, p = 0.0003), Larsen's grades (r = -0.62, p = 0.0002) and modified Sharp's method score (r = -0.69, p < 0.0001) in female patients only. CONCLUSIONS--A new, sensitive and reproducible technique of measurement of hand bone mineral content by DXA, has been developed and this method has been applied to normal volunteers and patients with RA. Hand dominance had no significant effect on hand BMC. After correcting for physical size, men have higher hand BMC than women. Hand BMC inversely correlates in women patients with disease duration and other validated methods of assessing radiological outcome in RA. Longitudinal studies are needed to establish its role in monitoring disease progression.
