Severe thrombocytopenia is an extremely rare complication of acute Epstein-Barr virus (EBV) infection. EBV infection usually causes hematological abnormalities, mainly atypical lymphocytosis, which is a feature of infectious mononucleosis, and uncomplicated cases often present with mild decreases in platelet counts. Our otherwise healthy, 21-year-old male Caucasian patient had thrombocytopenia and bleeding diathesis with platelet counts of 8 x 10(9)/L without other signs and symptoms of infectious mononucleosis. We commenced treatment with intravenous methylprednisolone before the acute EBV infection was serologically confirmed. Platelet counts initially rose and then fell after we stopped administrating corticosteroids. Repeated administration of methylprednisolone was followed by full recovery of the platelet count and normalization of formerly elevated transaminases. EBV infection may happen in children, adolescents and adults and this differential diagnosis should be considered in every patient presenting with acute thrombocytopenia.

Our aim was to analyze whether birth weight contributes to future hypertension through reduced kidney volume, and whether albuminuria could be a marker of this pathway. We included 103 patients with newly diagnosed essential hypertension and 92 normotensive controls. Blood pressure (BP) was measured using a mercury sphygmomanometer and a ABP monitor. Kidney volume was determined by ultrasound. Data on birth weight were obtained from mothers. Albuminuria was determined in 24-hour urine samples. Hypertensive patients had lower birth weight and higher albuminuria than normotensives. There was no difference in kidney volume between the two groups. We found a negative correlation between birth weight and systolic BP in the hypertensive group. BP was significantly correlated with BMI and albuminuria in the hypertensive group. Multiple regression analysis had shown the greatest impact of BMI on BP and had also demonstrated that 24-hour systolic BP showed the greatest risk for developing albuminuria in hypertensive patients. In conclusion, birth weight influences BP values in adult age, but it is not mediated by a reduced kidney volume. A strong correlation, independent of birth weight, was observed between albuminuria and BP values. Increased BMI is the most important independent risk factor responsible for BP increase, even in an early phase of essential hypertension.

Determination of anti-THP antibodies was not found to be useful in the early diagnosis of endemic nephropathy. The results suggest that most of the anti-THP antibodies are 'natural' and/or cross reactive. The highest values observed in the rural population could probably be explained by exposure to some ubiquitous antigen or more likely they are consequences of fever.
