A recent Canadian research survey on people with Psoriasis (not Psoriatic Arthritis), called the SKIN study (cute) suggests that PsA could be widely underdiagnosed. The article I read about the study states:
The SKIN survey reveals that half of all respondents [with Psoriasis] reported that they had developed joint pain or stiffness, but only 18 per cent of these respondents had ever received a diagnosis of psoriatic arthritis.and...
Respondents reporting no psoriatic arthritis diagnosis indicated that they experienced stiffness in the knees, shoulders and hips (48 per cent), followed by pain or stiffness in the finger joints (38 per cent) and toe joints (23 per cent).Underdiagnosis concerns me for two reasons - firstly, of course, I don't want anyone else to experience the pain I experience. But secondly, fewer people diagnosed with PsA means the research community will be less likely to study PsA.
A while back I wrote about the lack of research and basic information about Psoriatic Arthritis, as compared to Rheumatoid Arthritis and Psoriasis. Here's the link.
Here's my point: fewer scholarly articles on PsA will lead doctors to make fewer diagnoses, AND, the lack of PsA diagnoses certainly has an effect on how much research is undertaken.
So if you're out there with P, and think you have PsA, please consider getting a definitive diagnosis.
You know what they say about the squeaky wheel, after all. I'm up for some grease (and I'm not talking another ointment).
