A 25-yr-old black man with cystic fibrosis and cirrhosis developed symptoms of osteomalacia and hypocalcemia, hypophosphatemia, secondary hyperparathyroidism, and low circulating 25-hydroxyvitamin D (25-OHD). Serum 1,25-dihydroxyvitamin D (1,25-[OH]2D) was within the normal range. Iliac crest bone biopsy confirmed the diagnosis of osteomalacia. Oral administration of 50,000 IU of vitamin D2 failed to relieve symptoms or raise serum 25-OHD levels to normal. Intramuscular vitamin D2, 10,000 IU every 8-12 week, improved symptoms, raised serum 25-OHD to normal, and increased circulating 1,25-[OH]2D to values five times normal. Over the next 10 mo circulating 1,25-[OH]2D remained elevated despite normalization of serum calcium, phosphorus, and parathyroid hormone. Repeat bone biopsy 1 yr after parenteral vitamin D showed healing of the osteomalacia. Malabsorption of vitamin D appears secondary to profound steatorrhea due to pancreatic insufficiency and secondary biliary cirrhosis. Although extensive hepatocellular disease was present, hepatic conversion of vitamin D to 25-OHD was intact. Both high and low circulating 1,25-[OH]2D levels during active osteomalacia have been reported; initially, the level was in the normal range and higher values in this patient occurred with repletion of 25-OHD substrate. This study shows that symptomatic osteomalacia may be a major manifestation of cystic fibrosis in those patients surviving into adulthood. Measurements of serum 25-OHD in cystic fibrosis patients may identify those who should receive supplemental vitamin D.

Secretion of bile salts into the duodenum was studied in eight normal subjects, in 10 patients with cirrhosis, and in two cholecystectomized subjects. Duodenal juice was aspirated continuously through a double-lumen tube during an unstimulated period, after an intravenous injection of pancreozymin/cholecystokinin, and during a continuous intravenous infusion of secretin given at a rate of 3 units per kilogram body weight per hour. Precautions were taken to try to ensure quantitative recovery during the studies, and recovery of an infused nonabsorbable marker was greater than 80% in all subjects. Secretin induced a flow of a greater volume of juice in the cirrhotic patients than in the normal group (49 to 57 ml per 10 minutes compared with 28 to 49 ml per 10 minutes). This change may have resulted from a higher effective dose of secretin if it is assumed that the cirrhotic liver fails to catabolize secretin. The bile acid response to pancreozymin/cholecystokinin followed by secretin in the cirrhotic subjects resembled that seen in patients after cholecystectomy in whom pancreozymin/cholecystokinin induces only a slight increase in bile salt output but in whom the output of bile salts during rest and secretin stimulation is markedly greater than normal. This response in cirrhosis is probably best interpreted as due to impaired function of the gallbladder. The total amount of bile salt liberated over the two hours of the test in the cirrhotic patients was similar to normal The concentration of bile salt after pancreozymin/cholecystokinin was less than in normal subjects, but similar to that in cholecystectomized patients. It is unlikely therefore that deficient output or concentration of bile salt can be held responsible for steatorrhea in cirrhosis. THERE WAS A MARKED DECREASE IN THE DEOXYCHOLATE CONJUGATES AND A REDUCTION IN THE GLYCINE: taurine ratio in the bile of cirrhotic patients. The former change may reflect a change in bacterial flora and the latter a defect in hepatic conjugating mechanisms.

Iron absorption is under delicate control and the level of absorption is adjusted to comply with the body's need for iron. To measure the intestinal setting for iron absorption, and thereby indirectly assess body iron requirements, cobaltous chloride labelled with (57)Co or (60)Co was given by mouth and the percentage of the test dose excreted in the urine in 24 hours was measured in a gamma counter. Seventeen control subjects with normal iron stores excreted 18% (9-23%) of the dose. Increased excretion, 31% (23-42%), was found in 10 patients with iron deficiency anemia and in 15 patients with depleted iron stores in the absence of anemia. In contrast, 12 patients with anemia due to causes other than iron deficiency excreted amounts of radiocobalt within the normal control range. In patients with iron deficiency, replenishment of iron stores by either oral or parenteral iron caused the previously high results to return to normal.Excretion of the test dose was normal in portal cirrhosis with normal iron stores but it was markedly increased in patients with cirrhosis complicated by either iron deficiency or endogenous iron overload. It was also raised in primary hemochromatosis. Excretion of the dose was reduced in gluten-sensitive enteropathy. Gastrointestinal surgery and inflammatory disease of the lower small intestine had no effect on the results except that some patients with steatorrhea had diminished excretion.The cobalt excretion test provides the clinician with a tool for the assessment of iron absorption, the detection of a reduction in body iron stores below the level that is normal for the subject in question, the differentiation of iron deficiency anemia from anemia due to other causes, and the investigation of patients with iron-loading disorders.

Neurological syndromes similar to those associated with abetalipoproteinaemia or Friedreich's ataxia developed in four patients with chronic steatorrhoea, two of whom had cystic fibrosis and two chronic cirrhosis of childhood. Serum concentrations of vitamin E were virtually undetectable in all four patients. Substantial clinical improvement occurred in one patient after restoration of normal vitamin E levels by parenteral therapy. The findings suggest that spinocerebellar degeneration may be secondary to severe and prolonged vitamin E deficiency.

Forty five cases of chronic pancreatitis have been diagnosed between January 1966 to July 1983 in the Hospital A. Posadas. The diagnosis was confirmed by the presence of one or more of the following data: pancreatic calcifications positive in 35, abnormal secretin test 37, ultrasonography and computed tomography pathological findings 10. Surgical operations were carried out in 25 patients and biopsy taken in 5. Thirty nine (86.6%) were males, 6 (13.3%) females, the mean age in each group was 47.4 and 39.8 years. Chronic alcoholism was certain in 41 (91.9) patients, in the remainder 4 no other etiologic factors were found. The main clinical data were: Weight loss 38 (84.4%) diabetes 34 (75.5%) pain 33 (73.3% in 7 as acute pancreatitis) Steatorrhea 23 (51.1%) jaundice 16 (35.5%- 11 by extrahepatic biliary tree obstruction, 5 by hepatic cirrhosis) pseudocysts 12 (26.6%). The more common associated diseases were: hepatic cirrhosis 6, fatty liver 2 (17.7%) gastroduodenal ulcer 6 (13.3%) cancer 4 (8.8%--gastric 1, pancreatic 3). In order to study the frequency of the clinical data the patients were grouped according to the presence or absence of calcifications and the etiologic factor Symptoms and signs were matched and statistic analysis (coefficient association phi) was made. Only a moderate association between acute pancreatitis in no calcified group and diabetes in calcified group were found. The chronologic study of certains clinical data shows that acute pancreatitis, jaundice, pseudo-cyst and surgical operations were significative more frequent in the first five years while diabetes has little more frequency in the second five year period. Twenty six surgical operations were carried out in 25 patients; 20 (76.9%) due to complications, 6 (23.1%) secondary to pain (pancreatic resection 3, pancreatoyeyunostomy 2, exploration 1). Twenty three patients were lost to follow-up, 12 died and 10 are still alive. This last group was followed at regular period, 8 remained asymptomatic and 2 have intermittent abdominal pain related to alcoholic ingestion.

Intestinal bile salt deficiency marginally impairs fat absorption in cholestatic patients. The finding of massive steatorrhea in some patients with primary biliary cirrhosis led us to systematically study and compare fat digestion in control subjects (n = 4) and patients with biliary cirrhosis with (n = 11) and without (n = 3) steatorrhea. The jejunum was anatomically and functionally intact in all subjects, as demonstrated by normal gastrointestinal radiology and xylose absorption, respectively. The intestinal contents were recovered during digestion of a fat meal. Lipolysis, pH, and trypsin activity were measured in whole intestinal contents, whereas bile salts, total lipid, and fatty acid were determined in both total and aqueous phases. The results obtained in controls and patients without steatorrhea were similar. Percentage of lipolysis and intraluminal pH were normal in controls and in both patient groups. The intestinal contents of the patients with steatorrhea had a significantly lesser capacity to solubilize both total lipid and fatty acid in relation to abnormally low aqueous bile salt concentrations. No bile salt deconjugation and only minimal bile salt precipitation were found, thus low aqueous bile salts were strictly related to bile secretory failure. Steatorrhea was always present when aqueous bile salt levels were below 3.0 mM. Intestinal trypsin activity was subnormal in patients with steatorrhea; decreased trypsin activity was related (r = 0.82, p less than 0.001) to reduced intestinal bile salt levels. One patient was found to have severe exocrine pancreatic failure. Administration of medium chain triglycerides was uniformly effective in improving nutrition in patients with steatorrhea, but the course of the disease was unaffected. These results indicate that overt pancreatic failure is uncommon in primary biliary cirrhosis, and that fat maldigestion and steatorrhea, regardless of what degree, are due mainly to low intestinal bile salt levels secondary to bile secretory failure. Finally, subnormal pancreatic function in this disease appears to be related to the bile secretory failure, suggesting either that the lack of bile or bile salts in the intestine depresses pancreatic exocrine function or that both biliary and pancreatic secretions decrease in parallel as part of a widespread secretory failure syndrome.

Twenty-eight patients with cystic fibrosis, who survived to over 18 years of age are reported. The ages at the time of diagnosis ranged from and two and half months to over 21 years. Manifestations of cystic fibrosis in adults and youngsters are compared and contrasted. A review of the patients surviving shows that steatorrhea is under control. There is no evidence of biliary cirrhosis in any of these patients. Rectal prolapse has not been an important factor. Pseudomonas and Staphylococci were the major infecting organisms causing lung disease. Two-thirds of the patients do not use prophylactic antibiotics and one-third do not practice regular pulmonary care. Two female patients died; one of Pseudomonas lung infection and respiratory failure, after a pregnancy that was carried to term (live baby); one, of respiratory failure, also with severe Pseudomonas respiratory tract infection, two years after a pregnancy that was terminated in the first trimester.

The mechanisms of vitamin D deficiency already described are triggered off by a variety of causes. Confinement indoors leads to defective photosynthesis and dietary restrictions to insufficient intake. Malabsorption results from digestive tract diseases: mainly adult coeliac disease, but also sequelae of gastrectomy, exocrine pancreatic insufficiency, chronic biliary obstruction and all other causes of steatorrhoea. Practically, osteomalacia of digestive origin usually results from multifactorial hypovitaminosis D. The same applies to primary or nutritional biliary cirrhosis, which frequently entails low vitamin D blood levels despite subnormal 25-hydroxylation. Osteomalacia is also found in renal osteodystrophy, where it is partly due to inhibition of 1,25-hydroxylase and subsequent deficiency of 1,25-dihydrocholecalciferol, though other, non vitaminic substances may also be involved. Two misleading forms of the disease must be borne in mind: one with renal tubular lsions, the other associated with functional pseudo-hypoparathyroidism. The aetiology of most cases of osteomalacia due to vitamin D deficiency can be elucidated by a few simple tests.

Focal and multilobular biliary cirrhosis are considered pathognomonic of cystic fibrosis (CF) and almost invariably have been reported in patients with steatorrhea. In contrast, patients with pancreatic sufficiency and normal absorption are considered less likely to develop liver or biliary tract problems. The authors report three patients with CF and pancreatic sufficiency, presenting with recurrent abdominal pain (unrelated to pancreatitis). All had common bile duct disease, one with multilobular cirrhosis and portal hypertension. Pancreatic sufficiency was proven by quantitative pancreatic stimulation tests, 3-day fecal fat analyses, and serum pancreatic isoamylases. All three patients had mild lung disease. Two were homozygous for the common delta F508 mutation, and the other, a delta F508 compound heterozygote. Hepatobiliary structure and function were determined by serial hepatobiliary scintigraphy, percutaneous transhepatic cholecystography, and biochemical liver function tests. Patients 1 and 3 had mild hepatomegaly, normal liver biochemistry, and distal common bile duct strictures. Patient 2 had a firm nodular liver with splenomegaly, abnormal liver biochemistry, and a cholangiographic appearance of sclerosing cholangitis. All have undergone operative treatment for persistent abdominal pain. These cases confirm the occurrence of common bile duct pathology and liver disease in patients with CF and pancreatic sufficiency. They demonstrate that liver and biliary tract disease can occur independently of the underlying disease severity and the presence of steatorrhea. Further, they suggest that obstruction of the biliary tract may be an additional factor in the evolution of liver disease in CF.

We describe a 33-yr-old pregnant woman in whom a primary biliary cirrhosis-like syndrome developed after 2 wk of chlorpromazine therapy. The clinical course was characterized by severe jaundice lasting 22 mo, intense pruritus, fever, steatorrhea, high alkaline phosphatase levels and hypercholesterolemia. Jaundice resolved with initiation of ursodeoxycholic acid therapy, but subclinical cholestasis and low-level inflammatory activity persisted and ultimately evolved into biliary cirrhosis. The pathological substrate of this severe and prolonged cholestatic reaction was found to be the vanishing bile duct syndrome with a marked transient pseudoxanthomatosis.
