The aim of this study was to determine the prevalence of subclinical Achilles tendon disorder in cutaneous psoriasis patients and compare it with healthy controls.</span><br> <span style="line-height:13.8pt"><b><i><span style="color:blue">Methods:</span></i></b> This was a cross-sectional case-control study conducted on psoriasis patients that were referred to dermatology clinic. Thirty patients in the case group and 30 healthy controls were included in the study. Thickness of Achilles tendon enthesis was scanned by an expert rheumatologist using ultrasound equipped with a 5-14 MHz linear prob bilaterally.<span style="font-size:10.0pt"></span></span><br> <span style="line-height:13.8pt"><b><i><span style="color:blue">Results:</span></i></b> The mean age of the patient and control groups was 43.97&plusmn;16.82 years and 38.87&plusmn;12.71 years, respectively (P=0.190). The mean thickness of the Achilles tendon enthesis in the dominant limb was 4.31&plusmn;0.86 mm in the patient group and 4.10&plusmn;0.54 mm in the control group. There was no significant difference between the two groups in terms of thickness of the Achilles tendon enthesis in the dominant limb (P=0.276). The mean thickness of the Achilles tendon enthesis in the non-dominant limb was 4.44&plusmn;0.91 mm in the patient group and 4.14&plusmn;0.59 mm in the control group. There was no significant difference between the two groups in terms of thickness of Achilles tendon enthesis in the non-dominant limb (P = 0.134).<span style="font-size:10.0pt"></span></span><br> <span style="line-height:13.8pt"><b><i><span style="color:blue">Conclusion</span></i></b><i><span style="color:blue">:</span></i> Although ultrasonography may be utilized for assessment of both structural and inflammatory changes, we revealed no difference in the mean thickness of Achilles tendon enthesis in patients with cutaneous psoriasis. Contradiction between clinical and ultrasonography features required further research.<span style="font-size:10.0pt"></span></span></span></span><br> &nbsp; Cutaneous psoriasis, Achilles tendon, Ultrasound, Enthesis, Psoriatic arthritis. 313 317 http://caspjim.com/browse.php?a_code=A-10-2982-1&slc_lang=en&sid=1 Anwar Sharifaskari Sharifaskari.anwar@gmail.com 100319475328460047765 100319475328460047765 No Department of Internal Medicine, School of Medicine, Iran University of Medical Sciences, Tehran, Iran Azadeh Goodarzi goodarzi.a@iums.ac.ir 100319475328460047766 100319475328460047766 No Department of Dermatology, Rasoul Akram Medical Complex Clinical Research Development Center (RCRDC), School of Medicine, Iran University of Medical Sciences, Tehran, Iran Navid Davoody dr.n.davoody@gmail.com 100319475328460047767 100319475328460047767 No Department of Internal Medicine, School of Medicine, Iran University of Medical Sciences, Tehran, Iran Nahid Kianmehr kianmehrnahid@gmail.com 100319475328460047768 100319475328460047768 No Department of Internal Medicine, School of Medicine, Iran University of Medical Sciences, Tehran, Iran Ali Sepyani sepianyali@gmail.com 100319475328460047769 100319475328460047769 No Azad University of Medical Sciences Anousheh Haghighi haghighi533@yahoo.com 100319475328460047770 100319475328460047770 Yes Department of Internal Medicine, School of Medicine, Iran University of Medical Sciences, Tehran, Iran
