Progressive joint pain and swelling

Psoriatic arthritis (PsA) is consistent with the patient's joint pain, dactylitis, enthesitis, skin plaques, and radiographic findings, making it the most likely diagnosis. 

Rheumatoid arthritis (RA) is possible because of the patient's joint symptoms; however, it is not the correct answer because of negative RF and ACPA tests and skin plaques. 

Osteoarthritis might cause joint pain but does not typically present with prolonged morning stiffness, skin plaques, or the "pencil-in-cup" radiographic finding. 

Gout, an inflammatory arthritis, primarily affects the big toe and does not align with the patient's skin and radiographic manifestations. 

PsA is a chronic inflammatory arthritis that often develops in people with psoriasis. It affects roughly 0.05%- 0.25% of the general population and up to 41% of people with psoriasis. PsA is most seen in White patients between 35 and 55 years and affects both men and women equally. PsA is linked to a higher risk for obesity, hypertension, hyperlipidemia, type 2 diabetes, metabolic syndrome, and other conditions, including uveitis and inflammatory bowel disease.

Clinically, PsA presents with a diverse range of manifestations, encompassing peripheral joint inflammation, often with an asymmetric distribution; axial skeletal involvement reminiscent of spondylitis; dactylitis characterized by sausage-like swelling of fingers or toes; and enthesitis. Common symptoms or findings include early morning stiffness for > 30 minutes; joint pain, tenderness, and swelling; back pain aggravated by rest and relieved by exercise; limited joint motion; and deformity. Although most patients have a preceding condition in skin psoriasis, diagnosis of PsA is often delayed. Furthermore, nearly 80% of patients may exhibit nail changes, such as pitting or onycholysis, compared with about 40% of patients with psoriasis without arthritis. The heterogeneity of its clinical features often necessitates a comprehensive differential diagnosis to distinguish PsA from other spondyloarthropathies and rheumatic diseases. The most accepted classification criteria for PsA are the Classification of Psoriatic Arthritis (CASPAR) criteria, which have been used since 2006.

No laboratory tests are specific for PsA; however, a normal ESR and CRP level should not be used to rule out a diagnosis of PsA because these values are increased in only about 40% of patients. RF and ACPA are classically considered absent in PsA, and a negative RF is regarded as a criterion for diagnosing PsA per the CASPAR classification criteria. Radiographic changes show some characteristic patterns in PsA, including erosive damage, gross joint destruction, joint space narrowing, and "pencil-in-cup" deformity.

PsA treatment options have evolved over the years. Whereas in the past, nonsteroidal anti-inflammatory drugs, glucocorticoids, methotrexate, sulfasalazine, and cyclosporine were commonly prescribed, the development of immunologically targeted biological disease-modifying antirheumatic drugs (DMARDs) and targeted synthetic DMARDs since 2000 has revolutionized the treatment of PsA. Tumor necrosis factor inhibitors (ie, etanercept, infliximab, and adalimumab) have been shown to improve all domains (psoriatic and articular disease) of PsA and are considered a milestone in managing the condition. Other emerging therapeutic strategies in recent years have demonstrated efficacy in treating PsA, including monoclonal antibodies targeting interleukin (IL)-12, IL-23, and IL-17, as well as small-molecule phosphodiesterase 4 and Janus kinase inhibitors.

Although most of these options have the potential to be effective in all clinical domains of the disease, their cross-domain efficacy can vary from patient to patient. In some cases, treatment may not be practical or can lose effectiveness over time, and true disease remission is rare. As a result, clinicians must regularly assess each domain and aim to achieve remission or low disease activity across the different active domains while also being aware of potential adverse events.
