Aim of the study – to determine the risk factors for the early development of osteonecrosis and to analyze the results of surgical treatment of patients with systemic lupus erythematosus in the long term after total hip arthroplasty.Materials and methods. The study group included 42 patients with systemic lupus erythematosus (SLE) complicated by osteonecrosis (ON) of the femoral head, who underwent 59 total hip arthroplasty (THA) operations. Before surgery and 6–21 years after THA, in order to assess the long-term results of surgical treatment of patients, the following was assessed: activity of the underlying disease – according to the SLEDAI-2K (Systemic Lupus Erythematosus Disease Activity Index 2000); the severity of irreversible changes in internal organs – according to the SLICC/ACR index of damage (Systemic Lupus International Collaborating Clinics/American College of Rheumatology); the clinical and functional state of the hip joint – according to the HHS (Harris Hip Score); the intensity of pain syndrome – according to the visual analogue scale (VAS); quality of life (QOL) – using the SF-36 questionnaire. The concentration of antibodies to cardiolipin (aCL) of IgM and IgG isotypes was determined by enzyme-linked immunosorbent assay (normal range – 0.0–10.0 GPL for IgM, 0–7 MPL for IgG).Results. After 6–21 years of follow-up after THA, there was a statistically significant decrease in pain intensity according to VAS, improvement according to the HHS from 40.0±14.9 to 83.3±17.4 points, SLE activity according to the SLEDAI-2K from 0 to 20 points (median – 4 [4; 8] points) before surgery and from 0 to 41 points (median – 0 [0; 4] points) after a long period of observation. There was a pronounced statistically significant positive dynamics for all QOL indicators studied (p≤0.005 in all cases). The most significant changes were found on the scales RE (Role-Emotional), RP (Role-Physical Functioning) and BP (Bodily Pain). The early development of ON was associated with the degree of activity of the underlying disease, the cumulative dose of glucocorticoids, kidney damage and arthritis in the first year from the onset of SLE, as well as hematological disorders and the presence of aCL in the blood serum 3 years before the onset of ON. The total number of complications was 10.2%.Conclusion. Total hip arthroplasty in patients with systemic lupus erythematosus can achieve a statistically significant reduction in pain intensity, increase functional activity and improve their quality of life.

Objective: to identify risk factors for the development of the femoral head aseptic necrosis (FHAN) and osteoarthritis (OA) of the hip joint (HJ) in patients with systemic lupus erythematosus (SLE) according to a retrospective analysis.Material and methods.The retrospective study included data from the case histories of 103 patients with SLE who underwent total hip arthroplasty (HA) (unilateral in 82 patients, bilateral in 21). The total follow-up period ranged from 2 years to 21 years. Among the patients included in thestudy, the majority were women (86.4%), the ratio of women and men was 7:1. At the time of surgery, the average age of women was 36.3±13.25 years, men – 36.2±9.57 years, duration of the disease – 168.0±132.5 months. SLE activity was assessed using the SLEDAI-2K scale. All patients were taking glucocorticoids (GC). The average duration of GC treatment was 89.0±87.2 months. 71.8% of patients received immunosuppressive therapy: hydroxychloroquine – 55.3%, azathioprine – 10.7%, methotrexate – 5.8%. The functional status of hip joint was determined using the Harris scale; by the time of surgery, the average score was 45.6±13.1 points. Pain intensity was assessed using a visual analogue scale and reached an average of 70.1±16.0 mm.Results and discussion. In 58.5% of patients with SLE, the indication for HA was FHAN (Group 1) and in 41.6% – OA of HJ (Group 2). At the time of HA, the duration of the disease was longer and the age was higher in group 2 than in group 1 (p<0.05). An analysis of individual clinical manifestations of SLE that preceded the development of HJ pathology revealed that arthritis and the presence of an antinuclear factor, ANF, were associated with the development of FHAN (p=0.022 and p=0.04, respectively). At the onset of the disease, patients of the 1st group, compared with patients of the 2nd group, more often had lesions of the skin, kidneys and serositis (22.9 and 20.5%; 14.5 and 11.7%; 68.7 and 64.7 %, respectively), but they were less likely to have mucous membranes and the central nervous system (CNS) involvement (14.5 and 23.5%; 10.4 and 17.6%, respectively). However, these differences did not reach statistical significance. Almost all of these disease manifestations, with the exception of the mucous membranes and the CNS lesions, were more often observed in patients with the development of FHAN, which indicates a higher activity of the disease at the onset of SLE. At the time of HA, we did not find any relationship between SLE activity and FHAN formation and hip OA. Patients of the 1st and 2nd groups in the same number of cases had mild (56.2 and 58.8%, respectively) and moderate (35.4 and 32.4%, respectively) activity according to SLEDAI-2K. No activity (SLEDAI-2K – 0 points) was also observed in patients of both groups with the same frequency (8.3 and 8.8% of cases, respectively). Associations of cumulative and daily doses of GC with the development of FHAN and OA of HJ were not revealed. In the 1st group, the average daily dose of GC was slightly higher, and the cumulative dose was less than in the 2nd group (8.59±4.75 and 7.79±5.39 mg; 20.0±11.9 and 23.8±19.2 g, respectively), but these differences were not significant (p>0.05).Conclusion. In SLE patients, the incidence of FHAN and HJ OA was comparable. At the time of HA, SLE patients with HJ OA were older and had a longer duration of the disease than patients with FHAN. The risk factors for FHAN were arthritis and ANF positivity at the onset of SLE.

Objective. To analyze early surgical outcomes after total hip replacement in systemic lupus erythematosus (SLE) patients.Subjects and Methods. The study included 42 SLE patients with femoral head osteonecrosis (ON) undergoing 59 total hip replacement (THR) surgeries at the traumatology and orthopedics department of VA Nasonova Research Institute of Rheumatology during 1998-2013 yy. All patients were thoroughly evaluated at baseline and one year after surgery using the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K), damage index (DI) of the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) to assess the degree of irreversible organ damage, Harris hip function scale, and VAS for pain intensity to assess early results of THR procedure.Results. Significant improvement of pain intensity was documented based on VAS assessments, as well as hip function improvement from 40,0±14,9 (13,8 – 82,7) to 80,8±12 (46,7-96,0) scores based on Harris scale, improvement of SLE activity based on SLEDAI-2K assessment: from 0 -20 scores (median 4[4;8]) at baseline to 0 – 43 scores (median 0[0;4]) at one year, and DI – from 0-12 (median 3[2;5]) to 0 -15 scores one year after THR procedure. Complications including dislocation of femoral component, peroneal nerve paralysis, periprosthetic fracture, venous thrombosis, and delayed wound healing were documented totally in 10,2% of patients. No post-surgery deaths occurred.Conclusion. The results obtained are indicative of better pain control and improved hip function following THR in SLE patients.
