Objective To assess bone mineral density (BMD) changes in patients with systemic lupus erythematosus (SLE) undergoing longterm therapy with corticosteroids (CS) while taking calcium, calcitriol, or alendronate. The primary endpoint was BMD changes at 2 years. Methods Premenopausal SLE patients were randomized into 3 groups according to medication: calcium carbonate 500 mg bd (calcium alone), calcitriol 0.25 μg bd plus calcium carbonate 500 mg bd (calcitriol + calcium), and alendronate 70 mg/week plus calcium carbonate 500 mg bd (alendronate + calcium). BMD was measured at baseline and at the end of the first and second years. Results Ninety-eight patients were recruited. There were 33 patients taking calcium alone, 33 calcitriol + calcium, and 32 alendronate + calcium. On randomization, median duration of CS use was 2.5 years (range 0–20 yrs). Seventy-seven patients (78.6%) completed the study (23 taking calcium alone, 27 calcitriol + calcium, 27 alendronate + calcium). There were no significant differences in mean CS dosages among the 3 groups at the time of BMD measurements. After 2 years, there were no significant changes in BMD in the calcium-alone and calcitriol + calcium groups, apart from a 0.93% (p < 0.001) reduction in total hip BMD in the calcium-alone group. In contrast, the alendronate + calcium group showed significant increases in BMD of 2.69% (p < 0.001) in the lumbar spine and 1.41% (p < 0.001) in total hip. Conclusion Both calcium alone and calcitriol + calcium preserved lumbar spine BMD in premenopausal patients with SLE taking longterm CS at 2 years, whereas alendronate + calcium led to increases in BMD in lumbar spine and total hip. Premenopausal women taking CS should be considered for osteoporosis prophylaxis.

The aim of this study was to assess the bone mineral density (BMD) of premenopausal patients with systemic lupus erythematosus (SLE) on corticosteroids (CS) and to determine the influence of CS and other risk factors on BMD. A total of 98 premenopausal patients with SLE were recruited from outpatient clinics in two teaching hospitals. Risk factors for osteoporosis were determined, and BMD was measured using dual-energy x-ray absorptiometry. The mean age of the patients was 30.05 ± 7.54 years. The mean dose of prednisolone at time of BMD measurement was 18.38 ± 10.85 mg daily. Median duration of CS use was 2.5 years (range 0–20). Median cumulative dose of CS was 9.04 g (range 0.28–890.0). Six patients (6.1%) had osteoporosis, 41 (41.9%) had osteopenia and 51 (52.0%) had normal BMD. Lumbar spine T score correlated with cumulative CS dose (P = 0.019). Duration of CS intake correlated with femoral neck T score (P = 0.04) and trochanter T score (P = 0.008). There was no correlation between BMD and race, SLE Disease Activity Index score, smoking and self-reported calcium intake or exercise. Only 52% of these patients had normal BMD. The duration and cumulative dose of CS intake was significantly correlated to BMD, but not the other commonly assessed risk factors. These findings suggest that premenopausal patients with SLE on CS should have their BMD measured at regular intervals to fully assess their osteoporosis risk.

To determine the depth and sources of knowledge about osteoporosis (OP) among the public in Malaysia. A self-administered questionnaire was distributed to attendees of health-related public forums. A total of 87.1% of the attendees had heard of OP. Of these, 89.5% were concerned about getting OP. Significantly more women than men (P = .015), those with more than 10 years of schooling (P < .001), and those earning more than

US285 per month (P = .022) had heard of OP. Knowledge of OP risk factors was good: 97.1% identified low calcium intake, 87.8% lack of exercise, 80.0% family history of OP, and 75.8% postmenopausal status. A total of 38.7% of the attendees thought that OP was more serious than cancer and 35.1% more serious than heart disease; 55.7% obtained information about OP from newspapers and 46.4% from magazines. In this self-selected population, women, the better educated, and those earning higher incomes were more aware of OP. Knowledge of OP was obtained mainly from printed materials.

A survey on the management of gout in Malaysia.

Swan Sim Yeap; Emily Man Lee Goh; Suk Chyn Gun

We investigated the association of the HLA genes in Malaysian patients with systemic lupus erythematosus (SLE) and their associations with the clinical manifestations in 160 SLE patients (99 Chinese and 61 Malays) and 107 healthy control individuals (58 Chinese and 49 Malays) were studied. Sequence specific primer amplification (PCR-SSP) phototyping techniques were used to analyse 25 HLA-A allele groups, 31 HLA-DR allele groups and 9 HLA-DQ allele groups. Appreciable increases in allele frequencies of HLA-A*11, DRB1*0701, DRB1*1601-1606, DRB5*01-02 and DQB1*05, and decrease in HLA-DRB1*1101-1121, 1411, DRB1*1201-3, DRB1*1301-22, DRB3*0101, 0201, 0202, 0203, 0301 and DQB1*0301, 1304 in SLE patients compared with healthy control individuals. However, after Bonferroni correction (p(c)<0.05) only HLA-A*1101, 1102, DRB5*01-02, DQB1*05, DRB1*1201-3, DRB3*0101, 0201, 0202, 0203, 0301 and DQB1*0301, 0304 remained significant. Allele frequencies of DRB1*0701 and DRB4*0101101, 0102, 0103, DQB1*05, DRB1*1301-22, DRB3*0101, 0201, 0202, 0203, 0301 and DQB1*0301, 0304 were significantly increased in Malay SLE patients compared with healthy control individuals. In contrast, Chinese SLE patients had increased allele frequencies of DRB1*1601-1606, DQB1*05, DRB1*1201-3, DRB3*0101, 0201, 0202, 0203, 0301, DRB3*0101, 0201, 0202, 0203, 0301 and DQB1*0301, 0304 compared with healthy control individuals. HLA-A*6801-02 and DRB1*1601-1606 frequencies appeared elevated in a subset of patients with serositis and DRB1* 0401-1122 frequency was elevated in those displaying neurologic disorder. However, unequivocal evidence of these associations would require investigation of substantially larger cohorts. On the whole, our findings suggest that HLA allele associations with SLE are race specific in Malays and Chinese.

Rheumatoid arthritis in paintings: a tale of two origins.

Swan Sim Yeap

Objective The aim of this study was to investigate the correlations between serum cartilage oligomeric matrix protein (COMP), interleukin-16 (IL-16) and different grades of knee osteoarthritis (KOA) in Malaysian subjects. Methods Ninety subjects were recruited comprising 30 with Kellgren-Lawrence (K-L) grade 2 KOA, 27 with K-L grade 3 KOA, 7 with grade 4 KOA, and 30 healthy controls. All subjects completed the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire. Serum COMP and IL-16 levels were measured using ELISA and their values log transformed to ensure a normal distribution. Results There was no significant differences in levels of log serum COMP and IL-16 between healthy controls and KOA patients. There were no significant differences in the log serum COMP and IL-16 levels within the different K-L grades in the KOA patients. In KOA patients, log serum IL-16 levels significantly correlated with the WOMAC score (p = 0.001) and its subscales, pain (p = 0.005), stiffness (p = 0.019) and physical function (p<0.0001). Serum IL-16 levels were significantly higher in Malaysian Indians compared to Malays and Chinese (p = 0.024). Conclusions In this multi-ethnic Malaysian population, there was no difference in serum COMP and IL-16 levels between healthy controls and patients with KOA, nor was there any difference in serum COMP or IL-16 levels across the various K-L grades of KOA. However, there were significant inter-racial differences in serum IL-16 levels.

The association between HLA genes and radiological erosions in Malaysian patients with rheumatoid arthritis

Rheumatoid arthritis (RA) is thought to be a ‘recent’ disease in that descriptions of it were only noted in the 17th century. However, a study of paintings would suggest that RA could have been present as early as the 15th century, when artists started to paint the human body accurately rather than figuratively. Thus, it was possible to deduce from their paintings the occurrence of various medical conditions. If present, RA with its typical finger deformities should be apparent. This review discusses the known occurrences of RA‐type deformities in paintings and places this in the context of the origins of the disease.
