The level of serum 25-hydroxyvitamin D (25-OH-D3) was determined in 94 cases of healthy volunteers and 98 patients with various diseases. The mean level of the controls was 16.2 +/- 4.6 ng/ml (x /- S). The patients were divided into 5 groups, 1) Osteomalacia and rickets 42 cases, showing typical changes of bone in X-ray films. In 12 of them the disease was caused by vitamin D deficiency. The mean value of 25-OH-D3 was 3.3 +/- 2.0 ng/ml, being much lower than that of controls (P less than 0.001). In 14 cases of hypophosphatemia, 8 cases of renal tubular acidosis and 8 cases of renal insufficiency all complicated with osteomalacia the mean value of 25-OH-D3 was 17.9 +/- 11.4, 18.2 +/- 9.6 and 19.2 +/- 5.6 ng/ml (P greater than 0.05) respectively. 2) Intestinal malabsorption 18 cases. The mean level of 25-OH-D3 was 4.5 +/- 3.2 ng/ml (P less than 0.001). Some of them had hypocalcemia and/or secondary hyperparathyroidism. 2 showed osteoporosis and 1 osteomalacia. 3) Chronic liver disease 24 cases, the mean value of 25-OH-D3 was 6.2 +/- 5.6 ng/ml, being much lower than that of the controls (P less than 0.001). 4) 10 cases after taking anti-epileptic drugs had a mean level of 25-OH-C3 6.9 +/- 5.8 ng/ml (P less than 0.001). 1 had X-ray evidence of osteomalacia. 5) 4 cases of overdosage of vitamin D had a mean value of 110.3 +/- 22.5 ng/ml, being much higher than that of the controls (P less than 0.001). Competitive protein binding assay for measuring 25-OH-D3 is a simple and economic method. It is sensitive and specific as it provides distinct discrimination between healthy controls and patients with vitamin D deficiency or overdosage.

Chronic diarrhea is a common complaint in gastroentology department, which is classified into a variety of types. While as eosinophilic gastroenteritis is a rare cause. A 50-year-old male patient was admitted with a 2-year history of diarrhea worsened for 10 months. Fasting could alleviate the diarrhea. Laboratory findings demonstrated anemia, low vitamins and minerals, fat malabsorption and abnormal D-xylose absorption test, delayed gastric emptying. According to the endoscopic biopsy of gastrointestinal mucosa, the diagnosis of eosinophilic gastroenteritis was made. Diabetic neuropathy may aggravate the symptom. The diarrhea resolved after the administration of steroids.
