Review Meta AnalysisUse of serum procalcitonin to detect bacterial infection in patients with autoimmune diseases: a systematic review and meta-analysis.
To systematically review evidence of the accuracy of the procalcitonin test for diagnosis of bacterial infection in patients with autoimmune disease. ⋯ Procalcitonin has higher diagnostic value than CRP for the detection of bacterial sepsis in patients with autoimmune disease, and the test for procalcitonin is more specific than sensitive. A procalcitonin test is not recommended to be used in isolation as a rule-out tool.

Normalization of widespread hyperesthesia and facilitated spatial summation of deep-tissue pain in knee osteoarthritis patients after knee replacement.
The modest association between radiographic joint damage and pain in osteoarthritis (OA) has led to the suggestion of facilitated central pain processing. This study evaluated the importance of ongoing tissue pathology in the maintenance of enhanced central pain processing. ⋯ The widespread hyperesthesia and enhanced spatial summation observed in OA patients imply sensitized central pain mechanisms together with the loss of CPM. Normalization of the results following joint replacement implies that these central pain processes are maintained by peripheral input.

Progressive multifocal leukoencephalopathy associated with immunosuppressive therapy in rheumatic diseases: evolving role of biologic therapies.
To evaluate the association of progressive multifocal leukoencephalopathy (PML) with immunosuppressive therapy for autoimmune rheumatic diseases (ARDs). ⋯ PML has been reported in patients with ARD treated with various immunosuppressive agents. The limitations of this study preclude definitive attribution of causality. While the paucity of confirmed cases recently exposed to anti-TNF therapy suggests a causal relationship is unlikely, a specific signal is emerging with regard to rituximab and PML. Although this is a rare adverse event associated with RTX therapy, the devastating nature of PML mandates continued vigilance, particularly in patients with current or prior exposure to an alkylating agent.

Computed tomography findings of pulmonary venoocclusive disease in scleroderma patients presenting with precapillary pulmonary hypertension.
Pulmonary venoocclusive disease (PVOD) is an uncommon form of pulmonary hypertension (PH) characterized by obstruction of small pulmonary veins. Pulmonary venous involvement has been reported in pathologic assessment of patients with systemic sclerosis (SSc) presenting with precapillary PH. High-resolution computed tomography (HRCT) of the chest is a noninvasive diagnostic tool used to screen for PVOD. No HRCT data are available on SSc patients with precapillary PH. We undertook this study to evaluate the frequency and effect on prognosis of HRCT signs of PVOD in SSc patients with precapillary PH. ⋯ HRCT signs of PVOD are frequently observed in SSc patients with precapillary PH, correlated with histologic assessment, and were associated with a high risk of pulmonary edema.
