OBJECTIVE: Psoriasis and psoriatic arthritis (PsA) are closely linked to cancer, as supported by the literature. Systemic treatments for psoriasis and PsA, namely non-biological disease-modifying anti-rheumatic drugs (DMARDs), have been associated with increased cancer risk in both conditions. New, more effective biological DMARDs (bDMARDs) do not seem to be associated with higher overall cancer risk compared to those not receiving bDMARDs, opening up possibilities for treating patients with previous or ongoing oncological disease alongside psoriasis and PsA. However, limited literature exists on treating PsA patients with cancer with bDMARDs. This study aims to assess the safety of secukinumab, a bDMARD, in patients with PsA and concurrent cancer. Here, we describe a case series of four patients with PsA treated with bDMARD secukinumab and review the literature on the subject. CASE SERIES: We assessed the laboratory parameters and clinical characteristics of 4 patients with PsA treated with the bDMARD secukinumab and followed up until 30 months. Three patients had oncological disease in remission, while one had active neoplasia. No cancer progression was observed during the treatment of these patients with secukinumab. CONCLUSIONS: In conclusion, our case series, consisting of four PsA patients with concurrent neoplasia treated with secukinumab, showed no evidence of cancer progression and represents the first case of PsA described in the literature treated during active oncological disease, lending support to the safety of secukinumab for the treatment of patients with PsA and concomitant neoplasia.

Background. Intradermal therapy (mesotherapy) is a technique used to inject drugs into the surface layer of the skin. The intradermal micro deposit allows to modulate the kinetics of drugs, slowing down its absorption and prolonging the local mechanism of action. This technique is applied in the treatment of some forms of localized pain when a systemic drug-saving effect is useful, when it is necessary to synergize with other pharmacological or non-pharmacological therapies, when other therapies have failed or cannot be used. Aim. The purpose of our study was to evaluate the effect of a mixture with respect to its lower concentration. We also wanted to evaluate the number of sessions needed to reach the therapeutic goal (50% reduction in pain from baseline) in patients with acute or chronic neck pain. Method. We analyzed retrospectively data from 62 patients with cervicobrachial pain treated with intradermal drugs. Group A received a mixture of drugs; group B received half the dose of drugs. Results. Patients who received a lower concentration of drugs achieved similar results to those who received a higher dose. The therapeutic goal was achieved on average with 3.5 + 1.7 sessions on a weekly basis (min 1; max 9). Subjects in group A required 4±1.7 treatments (min 1; max 9), while subjects in group B required 3±1.5 treatments (min 1; max 7). Conclusions. Our study confirms that even a lower dose of drugs can induce a clinically useful result. This study confirms that the useful effect of mesotherapy is only partly due to the pharmacological action. Further randomized prospective studies are needed to standardize the technique in the various pain syndromes, but it is recommended to follow the guidelines of the Italian Society of Mesotherapy to ensure patients receive appropriate treatment.
