RESUMEN

BACKGROUND: In patients with systemic lupus erythematosus (SLE), persistent joint activity and treatment with glucocorticoids are associated with musculoskeletal complications. About 30% of these patients become candidates for surgical treatment. The aim of this study was to evaluate postoperative outcomes after total hip arthroplasty (THA) in SLE patients. METHODS: We performed a retrospective cohort study at a tertiary care center in Mexico City between 1995 and 2013. All patients with SLE who underwent THA during that period were included (n = 58). They were compared with 2 control groups, one from another inflammatory arthropathy (rheumatoid arthritis, n = 58) and other noninflammatory (osteoarthritis, n = 58), matched by gender and date of surgery. The primary outcome was the frequency of postoperative complications during follow-up. RESULTS: We included 174 patients who underwent THA during the study period. Patients with SLE were younger (P < .0001), had a longer hospitalization stay (P = .001), and required more transfusions (P = .004). Global complications in THA in patients with SLE were more prevalent than rheumatoid arthritis (36.2% vs 15.5%, P = .029) and osteoarthritis (36.2% vs 5.1%, P < .0001) patients. After multivariate analysis, risk factors for THA complications were: SLE (hazard ratio 2.8, 95% confidence interval 1.2-6.8; P = .018) and low postoperative hemoglobin (hazard ratio 0.77, 95% confidence interval 0.73-0.83; P < .0001). Long-term complications after THA were similar among groups. CONCLUSION: This is the largest single-center study regarding clinical outcomes after THA in SLE patients. Our data suggest that SLE is an independent risk factor for adverse postoperative outcomes, mainly immediate complications, but the long-term outcome is good enough to offer surgical treatment that will improve quality of life.

RESUMEN

BACKGROUND: Rheumatoid arthritis (RA) is a complex inflammatory disease that modifies body composition. Although body mass index (BMI) is one of the clinical nutrition tools widely used to assess indirectly nutritional status, it is not able to identify these body alterations. Bioelectrical Vector Analysis (BIVA) is an alternative method to assess hydration and body cell mass of patients with wasting conditions. OBJECTIVE: To investigate the differences in nutrition status according to BMI groups (normal, overweight and obesity) and BIVA classification (cachectic and non-cachectic) in women with RA. METHODS: Women with confirmed diagnosis of RA were included from January 2015 to June 2016. Whole-body bioelectrical impedance was measured using a tetrapolar and mono-frequency equipment. Patients were classified according to BMI as: low body weight (n = 6, 2.7%), normal (n = 59, 26.3%), overweight (n = 88, 39.3%) and obese (n = 71, 31.7%), and each group was divided into BIVA groups (cachectic 51.8% and non-cachectic 48.2%). RESULTS: A total of 224 RA patients were included, with mean age 52.7 years and median disease duration of 12 years. Significant differences were found in weight, arm circumference, waist, hip, resistance/height, reactance/height and erythrocyte sedimentation rate among all BMI groups. However, serum albumin levels were significantly different between cachectic and non-cachectic patients independently of BMI. In all BMI categories, cachectic groups had lower reactance and phase angle than non-cachectic subjects. CONCLUSION: RA patients with normal or even high BMI have a significantly lower muscle component. Evaluation of body composition with BIVA in RA patients could be an option for cachexia detection.
