In this trial, subclavian-vein catheterization was associated with a lower risk of bloodstream infection and symptomatic thrombosis and a higher risk of pneumothorax than jugular-vein or femoral-vein catheterization. (Funded by the Hospital Program for Clinical Research, French Ministry of Health; ClinicalTrials.gov number, NCT01479153.).

Except for urinary pH, none of the outcomes differed between the two groups. Among ICU patients with stable renal function, the benefit of using sodium bicarbonate rather than isotonic sodium chloride for preventing contrast-associated acute kidney injury is marginal, if any.

Diffuse alveolar haemorrhage (DAH) is a rare but life-threatening complication of systemic lupus erythematosus (SLE). Specific therapy is based on a heavy immunosuppressive treatment that usually associates corticosteroid and cyclophosphamide boluses and plasma exchange. Despite this treatment, an early mortality rate of 20-50% is reported in the literature. Immunosuppression-related complications are responsible for further mortality and morbidity. Rituximab, a specific anti-CD20 antigen B-cell antibody, has been used with success for the treatment of several refractory autoimmune disorders, but rarely for SLE-induced DAH. We report here the first case of SLE-induced DAH treated successfully with rituximab without cyclophosphamide administration in a patient intolerant to cyclophosphamide. We review the two other cases of SLE-induced DAH managed with rituximab as a part of the immunosuppressive regimen.

CI-AKI was common in critically ill patients. pNGAL levels were higher in patients with sepsis or previous AKI, but did not help to diagnose CI-AKI any earlier than serum creatinine after CM injection. However, pNGAL could be of interest to detect patients at risk of subsequent RRT requirement.
