Paralysis of accommodation in infectious mononucleosis.

A case report of a 22-year-old patient with accommodative paralysis is presented including (1) the five-year history beginning with infectious mononucleosis; (2) recent clinical examination showing accomodative paralysis and reduced pupilary responses to light and near; (3) objective recordings confirming both the absence of any accommodation and the presence of pupillary responses to monocular and binocular near stimuli and to light, the latter with pupillary escape; and finally (4) neuropharmacological tests showing 7-diopter accommodative responses to pilocarpine (an acetylcholine substitute acting directly on the ciliary muscle receptor sites) and absent responses to demecarium bromide (a cholinesterase blocking agent which potentiates neurally released acetylcholine). Infectious mononucleosis includes ocular signs and symptoms. In young persons with accommodative difficulties, infectious mononucleosis should be suspected.

Primary Sjögren's syndrome after infectious mononucleosis.

A healthy young woman developed primary Sjögren's syndrome after protracted infectious mononucleosis. The diagnosis of primary Sjögren's syndrome was supported by histologic evidence of sialadenitis in labial salivary glands, rheumatoid factor, hypergammaglobulinemia, the HLA-B8 phenotype, and a high titer antibody to the anti-La (SS-B) nucleoprotein that co-precipitated the small ribonucleic acids encoded by Epstein-Barr virus, EBER 1 and EBER 2, as well as "host" RNA. There was strong humoral immunity to the Epstein-Barr nuclear and capsid antigens, but weak T-lymphocyte-mediated cytotoxicity to Epstein-Barr-transformed lymphoblasts, anergy to antigens used to elicit delayed-type hypersensitivity, and a low T-helper/T-suppressor cell ratio. The series of events initiated by infectious mononucleosis was attributed to a genetic defect in the immune response. Association of viral RNA with the La nucleoprotein resulted in a break in immunologic tolerance via a T-cell bypass effect with induction of anti-La (SS-B) by polyclonally activated B lymphocytes leading to autoimmune sialadenitis.

Pseudothrombocytopenia associated with infectious mononucleosis.

A 22-year-old man was hospitalized for assessment of thrombocytopenia and fever. Examination showed that he had infectious mononucleosis and moderately severe thrombocytopenia that was asymptomatic. Examination of blood smears revealed that the thrombocytopenia was caused by the clumping of platelets. We made a diagnosis of ethylenediaminetetraacetic acid-dependent pseudothrombocytopenia after excluding other infectious mononucleosis-related mechanisms of thrombocytopenia. When the patient recovered from infectious mononucleosis 2 months later, his thrombocytopenia improved, and no platelet clumping in peripheral blood smears was noted. Ethylenediaminetetraacetic acid-dependent pseudothrombocytopenia should always be considered as a possible cause of reported low platelet counts, even in patients with infectious mononucleosis and splenomegaly.
