I am noticing joint stiffness. Is it psoriatic arthritis?

Question

Hello doctor,

I am 37 and have psoriasis on my scalp and elbows. My dermatologist prescribed topical Clobetasol, which helped, but the patches come back once I stop.

My recent blood test revealed a mild elevation of liver enzymes (SGPT 58). So my concerns are -

Does that mean I should avoid oral medicines like Methotrexate?
Are the newer biologic injections safe for long-term use, and do they require frequent blood tests?
Also, can diet changes like avoiding dairy or gluten really make a difference in psoriasis flare-ups, or is that just anecdotal?
I also notice joint stiffness in the mornings. Could it mean psoriatic arthritis starting, and should I test for it?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Thank you for sharing this in such detail. I understand how frustrating it can be when psoriasis keeps returning despite treatment, especially when you are already taking good care of yourself.

Clobetasol is a strong topical steroid and works well for short-term control. Still, as you have noticed, psoriasis often recurs once treatment stops because it is a chronic inflammatory condition rather than a simple skin issue.

Your mildly elevated SGPT (serum glutamate pyruvate transaminase) (58) is only slightly above normal and can have many causes, including medications, fatty liver, or even recent illness.

However, since Methotrexate is metabolized by the liver, your dermatologist or rheumatologist would likely repeat the liver tests and evaluate the cause before considering it.

If the enzymes remain mildly elevated, other options, such as biologic injections (for example, Adalimumab, Secukinumab, or Ustekinumab) or non-hepatotoxic agents, might be safer choices.

These biologics are generally safe for long-term use under medical supervision and require periodic blood monitoring, though less frequently than Methotrexate, usually every three to six months.

Regarding diet, evidence on avoiding dairy or gluten is limited; some people do notice improvement with anti-inflammatory diets, but results vary and are often anecdotal.

Maintaining a healthy weight, avoiding alcohol, and managing stress have a more consistent positive effect.

The morning joint stiffness you describe suggests early psoriatic arthritis, especially if it lasts more than 30 minutes or affects the fingers, toes, or lower back.

It would be wise to mention this to your dermatologist or see a rheumatologist, who can order blood tests and possibly imaging to confirm early changes.

You are doing the right thing by paying attention to these symptoms, and with timely evaluation and the right treatment plan, both your skin and joint symptoms can be well controlled.

I hope this helps.

Thank you and take care.

Regards.
