A previously healthy 52-year-old man presents to an emergency department because of fever and severe abdominal pain accompanied by nausea, vomiting, and diarrhea. Emergency surgery is performed, and a segment of infarcted small bowel is resected. A pathologist who examines the resected specimen finds that the artery supplying the infarcted bowel is filled with clot and that a small, nodular lesion is present in the artery at the beginning of the clot. Histologic sections of this area of the vessel reveal numerous neutrophils in all layers. Follow-up studies on the patient show proteinuria, hematuria, and uremia. Which of the following viral infections has been most often linked to this patient’s disorder?
(A) Epstein-Barr virus
(B) Hepatitis A
(C) Hepatitis B
(D) Herpes simplex I
(E) Herpes simplex II

This pt's history, signs, symptoms & histologic findings are compatible with polyarteritis nodosa (PAN). Among the viruses mentioned above, HBV has been associated with PAN in almost 30% of the cases.
