<p>Methotrexate (MTX) is one of the first-line systemic treatment options in patients with moderate-to-severe plaque psoriasis and can be combined with narrow band UVB phototherapy (Nb-UVB). However, such a combination is rarely used for optimal duration due to safety and efficacy concerns. The aim of this study was to assess efficacy and safety of methotrexate (MTX) combination with low doses of Nb-UVB versus MTX monotherapy in patients with moderate-to-severe plaque psoriasis in a real-world setting. Retrospective psoriasis patient medical chart review was performed for the period from 2013 till 2019. The combination therapy group (Group 1, n = 74) received MTX 10 mg s/c once a week for four to six weeks and 311 nm UVB phototherapy according to the skin type and protocol of administration — three times a week; undergoing 10–24 procedures in the treatment course. The monotherapy group (Group 2, n = 57) was treated, using MTX as monotherapy 2.5 mg two times a day orally for five days (4–6 treatment courses in total). The combination therapy group achieved decrease of mean PASI at the end of the 2<sup>nd</sup> week of treatment by 38% vs monotherapy group 21%. Combination of low dose subcutaneous MTX and Nb-UVB therapy provides better treatment outcomes and normalisation of immunochemical parameters than for MTX monotherapy.
