RESUMO

OBJECTIVES: Temporal and geographic variations in knee osteoarthritis (OA) incidence occur worldwide. Regional variations also exist for socioeconomic status. We analyzed the association between socioeconomic deprivation (SED) and knee replacement (KR) incidence and assessed the proportion of KR associated with affluence. METHODS: Patients aged 15 years and over hospitalized for KR in 2013 were included. We linked each patient to a municipality of residence. Municipalities were matched to the 2011 European Deprivation Index score for SED analysis. Poisson regression was performed to examine the association between KR incidence and EDI adjusted for age and sex. The Population Attributable Fraction (PAF) was measured to calculate the proportion of excess of KR associated with social affluence. RESULTS: We included 77 597 KR. KR incidence decreased with increasing SED index. The EDI was significantly associated with KR incidence (P < 0.0001). The risk of KR is 2.36 times higher for persons living in the most affluent area compared to those living in the most underprivileged area. The PAF was 28.3%. CONCLUSIONS: The French administrative municipalities with the highest SED have the lowest age- and sex-adjusted KR incidence. It cannot be excluded that patients living in more privileged areas are overtreated. Complementary studies are necessary to define all the individual factors that limit or increase the access to knee replacement.

RESUMO

We report observations of a 47-year-old seropositive woman with rheumatoid arthritis (RA) suffering from mesangial immunoglobulin (Ig)A glomerulonephritis (GN) after initiation of abatacept, a selective T-cell co-stimulation modulator cytotoxic T-lymphocyte antigen 4 (CTLA4)-Ig. She was initially treated by corticosteroids, followed by methotrexate associated with a TNF inhibitor (adalimumab then switched to etanercept), finally switched to abatacept monotherapy, after secondary failure of these two forms of TNF inhibitors. Due to a progressively increased hematuria and proteinuria after abatacept therapy initiation, a renal biopsy was performed highlighting GN with mesangial IgA deposits, with necrosis and extracapillary crescent formations. IgA GN as a possible adverse event to abatacept was considered. Abatacept was stopped and a treatment by corticosteroids was initiated. Proteinuria decreased a couple of months after abatacept interruption. The short term between abatacept induction and IgA GN onset, as well as GN improvement since abatacept discontinuation, lend weight to the argument that CTLA4-Ig may play a crucial role in IgA GN pathogenesis. The possibility of a drug postponed adverse event justifies a long-term renal surveillance in RA patients treated by abatacept.
