A 67-years old woman developed sudden headache and transient vertigo. One week later, left arm paresis appeared and the patient became comatose. Investigations showed thrombocytopenia with hemolytic anemia and the presence of numerous irregularly contracted red cells (schizocytes). This was consistent with the diagnosis of thrombotic thrombocytopenic purpura. As focal neurological manifestations and widespread mental changes were still present when she emerged from coma, magnetic resonance imaging was performed showing numerous small infarcts in the white and grey matters.

A 65-year-old woman was admitted to our hospital because of severe anemia. A skin biopsy was done in January 1994 and sarcoidosis was diagnosed. Diffuse reticular shadows were seen in both lung fields on a chest X-ray film and mediastinal lymph node swelling was seen on a chest CT scan. She was followed as an outpatient and was not treated. She suddenly experienced vertigo and general fatigue in March 1995. Laboratory findings on admission were as follows: Hb 6.2 g/dl, MCV 115.9 fl, Ret 198%, LDH 732 IU/L, I-Bil 1.9 mg/dl, and Coombs' test was positive. Autoimmune hemolytic anemia was diagnosed, and she was treated with prednisolone (1 mg/kg). As of the time of this writing, she has no relapse of hemolytic anemia though prednisolone was discontinued 6 months ago.

The 33-year-old woman was violently beaten and suffered from concussion of the upper abdomen. Because of pain she took mefenamic acid for two days. Then she reported hematemesis, melena and vertigo. The value for hemoglobin was determined as 5.8 g/dl. Acute blood loss was suspected, but neither intraabdominal nor upper gastrointestinal hemorrhage could be detected. Further investigations revealed a Coombs-negative hemolytic anemia and thrombocytopenia, and microangiopathic hemolysis was suggested by the detection of fragmentocytes in a peripheral blood smear. The diagnosis of thrombotic thrombocytopenic purpura (TTP) was made, though the patient did not suffer from manifestations of impaired microcirculation like neurological symptoms or renal failure. The TTP was found to be associated with HIV infection. The hematological disease responded well to the treatment with fresh-frozen plasma.

A 57-year-old man developed vertigo, tinnitus, bilateral hearing loss and postural intolerance temporally related to the administration of pegylated interferon-alpha-2b/ribavirin for chronic hepatitis C viral infection. Clinical examination showed bilateral sensorineural hearing loss, subjective vertigo with saccadic intrusions during fixation and smooth visual pursuit, and supine hypertension followed by orthostatic hypotension with inadequate reflexive compensatory cardiovascular responses. Laboratory assessment showed marked hemolytic anemia. Formal audiometry revealed high-frequency sensorineural hearing loss with abnormal high-frequency distortion product otoacoustic emissions, indicative of damage to the cochlear outer hair cells. Cessation of therapy resulted in rapid clinical resolution with mild residual hearing loss and tinnitus. This case report illustrates vestibulocochlear and autonomic nervous system adverse effects of pegylated interferon-alpha-2b/ribavirin, emphasizing the importance of early recognition and cessation of therapy to prevent permanent neurootologic injury.

Antiphospholipid syndrome (APS) is an autoimmune disease with recurrent thromboses and pregnancy complications (90% are female patients) that can be primary and secondary (with concomitant autoimmune disease). Antiphospholipid antibodies are prothrombotic but also act directly with brain tissue. One clinical and one laboratory criterion is necessary for the diagnosis of APS. Positive serological tests have to be confirmed after at least 12 weeks. Clinical picture consists of thromboses in many organs and spontaneous miscarriages, sometimes thrombocytopaenia and haemolytic anaemia, but neurological cases are the most frequent: headaches, stroke, encephalopathy, seizures, visual disturbances, Sneddon syndrome, dementia, vertigo, chorea, balism, transitory global amnesia, psychosis, transversal myelopathy and Guillain-Barre syndrome. About 50% of strokes below 50 years of age are caused by APS. The first line of therapy in stroke is anticoagulation: intravenous heparin or low-weight heparins. In chronic treatment, oral anticoagulation and antiplatelet therapy are used, warfarin and aspirin, mostly for life. In resistant cases, corticosteroids, intravenous immunoglobulins and plasmapheresis are necessary. Prognosis is good in most patients but some are treatment-resistant with recurrent thrombotic events and eventually death.
