Key clinical point: Fibromyalgia and widespread pain were prevalent and associated with elevated disease activity in patients with psoriatic arthritis (PsA).

Major finding: Fibromyalgia and widespread pain were present in 11.1% and 20.6% of patients, respectively. The scores for Clinical Disease Activity in Psoriatic Arthritis were elevated in patients with vs without fibromyalgia (mean difference [Δ] 13.02; 95% CI 10.42-15.63) and in those with vs without widespread pain (Δ 11.94; 95% CI 9.96-13.92). Fibromyalgia was more prevalent in women (P < .001), patients with increased BMI (P = .002), patients diagnosed with spondyloarthritis (P = .005), and patients with a history of cardiovascular diseases (P = .004) and diabetes (P = .007).

Study details: This cross-sectional study included 1823 patients with PsA (age ≥ 18 years) from the CorEvitas US registry.

Key clinical point: Aortic stiffness was significantly higher in individuals with vs without psoriatic arthritis (PsA), and a longer disease duration was a predictor of increased aortic stiffness in the PsA population.

Major finding: Aortic stiffness, measured by carotid femoral pulse wave velocity, was significantly higher in patients with PsA than in healthy individuals without systemic inflammatory disease (7.80 vs 6.76 m/s; regression coefficient [β] 0.457; P_adj = .034). Aortic stiffness was positively associated with disease duration (β 0.028; P_adj = .020), red cell distribution width (Pearson correlation coefficient 0.190; P = .020), and systolic blood pressure (Spearman correlation coefficient [ρ] 0.351; P < .001), and inversely associated with glomerular filtration rate (ρ −0.264; P = .001).

Study details: This prospective PSOriatic Arthritis CARDiovascular Disease cohort included 150 patients with PsA and 88 healthy individuals without systemic inflammatory disease.

Key clinical point: Treatment with biologics significantly reduced the risk for psoriatic arthritis (PsA) development, including peripheral and axial PsA development, in patients with psoriasis.

Major finding: Patients treated at least once vs never treated with biologics had a significantly lower risk for PsA (8.9% vs 26.1%; adjusted odds ratio [aOR] 0.228; P < .001), including for peripheral PsA (aOR 0.182; P < .001) and peripheral PsA with axial involvement (aOR 0.115; P = .039). The protective effect of biologics against PsA persisted irrespective of the class of biologic used.

Study details: Findings are from an analysis of a cohort study that included 1023 patients with psoriasis aged 18 years or older, of whom 29.6% received biologics at least once and 21.0% had PsA.

Key clinical point: Bimekizumab improved disease impact in a rapid and sustained manner in patients with psoriatic arthritis (PsA) who were naive to biologic disease-modifying antirheumatic drugs (bDMARD-naive) or had prior inadequate response to tumor necrosis factor inhibitors (TNFi-IR).

Major finding: A numerically higher proportion of bDMARD-naive patients receiving bimekizumab vs placebo achieved a clinically meaningful improvement in disease impact at week 4 (20.3% vs 2.5%) and 16 (36.8% vs 10.1%). These improvements were sustained till week 52 in patients who received bimekizumab continuously (49.0%) and in those who switched from placebo to bimekizumab (44.4%). Results were similar in the TNFi-IR subgroup.

Study details: Findings are from two phase 3 studies including 1112 patients with PsA who were bDMARD-naive or TNFi-IR and were randomly assigned to receive 160 mg bimekizumab every 4 weeks (n = 698) or placebo with crossover to bimekizumab at week 16 (n = 414).

The Diagnosis: Erythema Ab Igne

Based on the patient's long-standing history of back pain treated with heating pads as well as the normal laboratory findings and skin examination, a diagnosis of erythema ab igne (EAI) was made.

Erythema ab igne presents as reticulated brownish erythema or hyperpigmentation on sites exposed to prolonged use of heat sources such as heating pads, laptops, and space heaters. Erythema ab igne most commonly affects the lower back, thighs, or legs^1-6; however, EAI can appear on atypical sites such as the forehead and eyebrows due to newer technology (eg, virtual reality headsets).⁷ The level of heat required for EAI to occur is below the threshold for thermal burns (<45 °C [113 °F]).1 Erythema ab igne can occur at any age, and woman are more commonly affected than men.⁸ The pathophysiology currently is unknown; however, recurrent and prolonged heat exposure may damage superficial vessels. As a result, hemosiderin accumulates in the skin, and hyperpigmentation subsequently occurs.⁹

The diagnosis of EAI is clinical, and early stages of the rash present as blanching reticulated erythema in areas associated with heat exposure. If the offending source of heat is not removed, EAI can progress to nonblanching, fixed, hyperpigmented plaques with skin atrophy, bullae, or hyperkeratosis. Patients often are asymptomatic; however, mild burning may occur.² Histopathology reveals cellular atypia, epidermal atrophy, dilation of dermal blood vessels, a minute inflammatory infiltrate, and keratinocyte apoptosis.¹⁰ Skin biopsy may be necessary in cases of suspected malignancy due to chronic heat exposure. Lesions that ulcerate or evolve should raise suspicion for malignancy.¹¹ Squamous cell carcinoma is the most common malignancy associated with EAI; other malignancies that may manifest include basal cell carcinoma, Merkel cell carcinoma, or cutaneous marginal zone lymphoma.^2,12-14

Erythema ab igne often is mistaken for livedo reticularis, which appears more erythematous without hyperpigmentation or epidermal changes and may be associated with a pathologic state.¹⁵ The differential diagnosis in our patient, who was in her 40s with a history of fatigue and joint pain, included livedo reticularis associated with lupus; however, the history of heating pad use, normal laboratory findings, and presence of epidermal changes suggested EAI. Lupus typically affects the hand and knee joints.¹⁶ Additionally, livedo reticularis more commonly appears on the legs.¹⁵

Other differentials for EAI include livedo racemosa, cutaneous T-cell lymphoma, and cutis marmorata. Livedo racemosa presents with broken rings of erythema in young to middle-aged women and primarily affects the trunk and proximal limbs. It is associated with an underlying condition such as polyarteritis nodosa and less commonly with lupus erythematosus with antiphospholipid or Sneddon syndrome.^15,17 Cutaneous T-cell lymphoma typically manifests with poikilodermatous patches larger than the palm, especially in covered areas of skin.¹⁸ Cutis marmorata is transient and temperature dependent.⁹

The key intervention for EAI is removal of the offending heat source.² Patients should be counseled that the erythema and hyperpigmentation may take months to years to resolve. Topical hydroquinone or tretinoin may be used in cases of persistent hyperpigmentation.¹⁹ Patients who continue to use heating pads for long-standing pain should be advised to limit their use to short intervals without occlusion. If malignancy is a concern, a biopsy should be performed.²⁰

The US Food and Drug Administration has granted accelerated approval to repotrectinib (Augtyro, Bristol Myers Squibb) for all locally advanced, unresectable, or metastatic solid tumors with an NTRK gene fusion that have progressed after initial treatment or that have no satisfactory alternative therapies.

The approval is a label expansion for the tyrosine kinase inhibitor (TKI), which received initial clearance in November 2023 for locally advanced or metastatic ROS1-positive non–small cell lung cancer. 

NTRK gene fusions are genetic abnormalities wherein part of the NTRK gene fuses with an unrelated gene. The abnormal gene can then produce an oncogenic protein. Although rare, these mutations are found in many cancer types.

The approval, for adult and pediatric patients aged 12 years or older, was based on the single-arm open-label TRIDENT-1 trial in 88 adults with locally advanced or metastatic NTRK gene fusion solid tumors.

In the 40 patients who were TKI-naive, the overall response rate was 58%, and the median duration of response was not estimable. In the 48 patients who had a TKI previously, the overall response rate was 50% and median duration of response was 9.9 months.

In 20% or more of participants, treatment caused dizziness, dysgeusia, peripheral neuropathy, constipation, dyspnea, fatigue, ataxia, cognitive impairment, muscular weakness, and nausea.

Labeling warns of central nervous system reactions, interstitial lung disease/pneumonitis, hepatotoxicity, myalgia with creatine phosphokinase elevation, hyperuricemia, bone fractures, and embryo-fetal toxicity.

The recommended dose is 160 mg orally once daily for 14 days then increased to 160 mg twice daily until disease progression or unacceptable toxicity.

Sixty 40-mg capsules cost around $7,644, according to drugs.com.
