Objective. To evaluate the effectiveness of balneotherapy (mud packs a
nd sulfur baths) on patients with psoriasis and psoriatic arthritis (P
sA). Methods. One hundred and sixty-six patients with psoriasis and Ps
A were treated at the Dead Sea for a period of 3 weeks. The patients w
ere divided into 2 groups. Both groups had the regular regimen of bath
ing in Dead Sea water and exposure to the sun's ultraviolet rays. The
study group, which consisted of 146 patients also was treated with mud
packs and sulfur baths. The control group, which had no additional th
erapy, consisted of 20 patients. The main clinical variables assessed
were duration of morning stiffness, grip strength, activities of daily
living, subjective patient assessment of disease severity, number of
active joints, number of effluent joints, Ritchie index, psoriasis are
a and severity index score, cervical, thoracic, and lumbar spine pain
and limitations of movement. Results. Statistically significant improv
ement was found in most variables in both groups. However, better resu
lts were observed in the study group. In 2 variables, reduction of spi
nal pain and range of movement in the lumbar spine, significant improv
ement (p < 0.001 and p = 0.022, respectively) was observed in the stud
y group only. Conclusion. Treatment of psoriasis and PsA at the Dead S
ea area is very efficacious and the addition of balneotherapy can have
additional beneficial effects on patients with PsA. Other controlled
studies with longer followup periods are needed to verify our results.
