[Non-tropical sprue discrepancy between clinical and biopsy findings. Five years' observation of a case (author's transl)].

After doagnosis and establishment of an appropriate diet a 51-year-old female patient with coeliac disease, who was critically ill in the beginning, became symptomless; nevertheless, a five year follow-up study with mucosa biopsies reveals a persisting villous atrophy with hyperplastic crypts ("flat mucosa"). This discrepancy between clinical and histological findings is discussed and it is emphasized that for coeliac patients a strict adherence to a gluten-free diet and bioptic supervision of therapy are essential. Treatment aimed solely at abolishing the clinical symptoms obviously bears the risk of a persisting symptomless illness and the danger of late complications.
