| Abstract |
| A 54-year-old woman and a 64-year-old man consulted
our clinic for dislocation of the distal interphalangeal (DIP) joints.
They both had been diagnosed as having Sjogren's syndrome.
In addition, interstitial pneumonia had been detected several years
earlier in both cases. Antibodies to SSA/Ro (52?kDa) and Jo-1 were
detected in their sera, but serum CK and aldolase levels were normal.
There were no eruptions, and muscle strength was normal in both patients.
The combination of the following six conditions, i.e., (1) multiple
dislocations of DIP joints, (2) interstitial pneumonia, (3) Sjogren's
syndrome, (4) positive anti-SSA antibodies (52?kDa), (5) positive
anti-Jo-1 autoantibodies, and (6) children with hypermobile joints
is quite rare and not observed frequently. Existence of the above
six conditions in two patients is even rarer. Therefore, the probability
that all six conditions would coincidentally coexist in each of the
two separate subjects is virtually zero. In this article, we propose
a novel clinical complex ? multiple dislocations of DIP joints, interstitial
pneumonia associated with Sjogren's syndrome, and positive
anti-SSA and anti-Jo-1 antibodies (DIPSSJ) ? as a new syndrome of
which clinicians should be aware. Because the children of both patients
had hypermobile joints, the syndrome may be partially genetic. |
