One hundred and fifty-eight patients with SLE were prospectively studi
ed at a tertiary referral centre in India to ascertain the prevalence
and clinical profile of fibromyalgia (FM) in Indian patients with lupu
s. An attempt was made to determine whether socio-demographic factors
or disease characteristics differ in SLE patients with and without FM.
Only 13 patients (8.2%) in our cohort were found to have fibromyalgia
. Their clinical profiles were similar to that reported in other serie
s. Corticosteroid withdrawal or dose reduction was the probable precip
itating factor in nearly one-third of our patients. Age, sex, marital
status, educational level, disease duration, disease activity and the
organ involvement in patients with SLE and FM were comparable to those
in patients not having FM. Fibromyalgia appears to be distinctly unco
mmon in Indian patients with lupus. A strong family support system, th
e virtual lack of disability benefits and/or racial variations in pain
threshold could be the likely factors responsible for the low prevale
nce of the disease observed in Indian patients with SLE.
