Entheseal involvement in asymptomatic human immunodeficiency virus infected patients: preliminary results of a clinical and ultrasonographic study.
CLINICAL AND EXPERIMENTAL RHEUMATOLOGY(2018)
Abstract
Objective As a strong association between human immunodeficiency virus (HIV) infection and spondyloarthritis (SpA) has been hypothesised, our main objective was to explore by power Doppler ultrasonography (PDUS) the presence of subclinical enthesitis in asymptomatic HIV patients. The presence of subclinical synovitis was also evaluated. Methods Consecutive asymptomatic HIV patients were studied and compared with asymptomatic HCV patients and healthy controls (HC). All subjects underwent a clinical and PDUS bilateral examination of the following entheses and joints: epicondyle, quadriceps, patellar, Achilles and plantar fascia; wrists, II and III metacarpo-phalangeal, knee and ankle. Results Twenty-nine HIV, 32 HCV and 25 HC were recruited; 1.032 entheses and 860 joints were examined. Clinical diagnosis of enthesitis was made in 10.3% HIV patients, 6.2% HCV patients (p=0.66) and none HC (p=0.24). PDUS enthesitis was found in 72.4% HIV, 28.1% HCV (p=0.0008) and 12% HC (p<0.0001). Clinical diagnosis of synovitis was made in 3.4% HIV patients, 9.3% HCV patients (p=0.61) and none HC (p=1). PDUS abnormalities were documented in 24.1% HIV patients, 71.8% HCV patients (p=0.0003) and none HC (p=0.0001). In detecting enthesitis and synovitis, PDUS was more sensitive than clinical examination both in HIV and HCV patients. Conclusion Our preliminary study shows the high frequency of PDUS enthesitis in asymptomatic HIV patients, which highlights the close link between HIV and SpA. Further studies are desirable on a larger number of HIV patients to confirm these results. PDUS proved to be more sensitive than clinical examination in detecting subclinical involvement of entheses and joints.
