[Addiction does not rule out somatic disease: don't let stigma influence diagnostic approach and treatment]. / Verslaving sluit somatische ziekte niet uit.

Addiction is a disease that occurs often and causes a large burden of disease. Patients are frequently stigmatized, also by health caregivers. As a result, care of patients with addiction is often sub-optimal and sometimes harmful. We present three patients in whom the focus on addiction, the diagnosis, and treatment of other somatic disorders has remained underexposed, with severe consequences for the patient. We discuss what stigmatization is and means for patients with addiction. We must recognize that professionals stigmatize, just as patients do themselves. There are effective interventions to help medical professionals destigmatize patients with addiction in their education and training. Every intervention starts with self-reflection on the stigma of addiction in every healthcare professional.

Hypotheses on the etiology of antineutrophil cytoplasmic autoantibody associated vasculitis: the cause is hidden, but the result is known.

The first description of what is now known as antineutrophil cytoplasmic autoantibody-associated necrotizing vasculitis appeared more than 140 yr ago. Since then, many aspects of the pathogenic pathway have been elucidated, indicating the involvement of antineutrophil cytoplasmic autoantibodies, but why antineutrophil cytoplasmic autoantibodies are produced in the first place remains unknown. Over the years, many hypotheses have emerged addressing the etiology of antineutrophil cytoplasmic antibody production, but no exclusive factor or set of factors can so far be held responsible. Herein is reviewed the most influential hypotheses regarding the causes of antineutrophil cytoplasmic antibody-associated vasculitis with the aim of placing in an epidemiologic background the different hypotheses that are centered on environmental and genetic influences.
