Summary
Thirty bilharzial patients were studied for their vitamin A status. Of the patients, 30% were found to have low-fasting serum retinol level below the acceptable level of 20 Μg/dl and one-third were presented with night blindness. Oral vitamin A therapy was effective in correcting the vitamin A deficiency among this group of patients.
Zusammenfassung
Drei\ig an Bilharzie erkrankte Patienten wurden auf ihren Vitamin-A-Status hin untersucht. 30% dieser Patienten hatten nüchtern gemessen einen sehr niedrigen Retinol-Serum-Spiegel, der noch unterhalb der Toleranzgrenze von 20 Μg/dl lag. Ferner litt ein Drittel dieser Patienten an Nachtblindheit. Innerhalb dieser Patientengruppe erwies sich die orale Vitamin-A-Therapie als sehr effektiv, um den Vitamin-A-Mangel auszugleichen.
