Cupriavidus pauculus is a Gram negative rod that is usually isolated in water and has been extraordinarily isolated in patients with vascular access and / or immunosuppression. In this work we present a series of cases of patients with positive blood cultures for cupríavidus pauculus, during a short period of time in our hospital center. The only characteristic related to all cases was the use of parenteral nutrition. It highlights the rareness of the microorganism and the susceptibility identified in the antibiogram, which may be useful for future cases.

Mononeuritis multiplex is characterized by multiple isolated neural injuries. Typically, these injuries result from ischemia, traumatic injury, compression, or connective tissue disease. Peripheral nervous system involvement is rarely found in antiphospholipid antibody syndrome (APS), and the association with asymmetric distal axonal polineuropathy is even rarer; the latter is more frequently found in systemic lupus erythematosus and in certain types of vasculitis as polyarteritis nodosa or vasculitis associated with anti-neutrophil cytoplasmic autoantibodies (ANCAs). 1-3 In this article, we report the case of a patient with mononeuritis multiplex associated with antiphospholipid antibodies. Our objective is to highlight this clinical manifestation associated with the presence of these antibodies, which is actually not considered as part of the classification criteria for APS or even the "extra criteria" manifestations, as well as the serology found and the treatment provided.
