A 36 year old man with panarteriitis nodosa (PAN) presented over a certain period of time meinly with gastrointestinal symptoms. He was HBsAg positive and a "reactive" hepatitis with histologically demonstrated. Arterial microaneurysms and stenoses were detected by angiography in the liver, kidney and small intestine. These findings were confirmed by autopsy. Vascular occlusions had caused infarctions of the small intestine as well as necroses and ulcerations of the large bowel. Chronic ischemia is considered as cause of the patient's malabsorption-syndrome. It is suggested, that cachexia of PAN may be partly due to malabsorption.

A newborn infant with congenital cytomegalic inclusion disease had spontaneous fractures of the distal radii bilaterally, and involvement of the metaphyseal portions of the humeri, ulnas, femurs, and tibias. The fractures healed promptly without complications under ordinary management. At the present time, one can only speculate on the cause of these lesions. Viral osteomyelitis, osteomalacia secondary to hepatitis and malabsorption and a disturbance of endochondral ossification are all possibilities. There is a need for additional cases with histologic and biochemical studies of the bone lesions in congenital cytomegalic inclusion disease.

Serum 25-hydroxy-vitamin D (25-OHD) concentrations were measured in 49 patients with hepatobiliary disease in infancy. Low mean values were found in groups of patients with biliary atresia, neonatal hepatitis, choledochal cyst, and chronic intrahepatic cholestatic syndrome. In the group of patients with surgically repaired biliary atresia, the mean value did not differ from normal. Parenteral vitamin D increased 25-OHD in serum in patients with biliary atresia, but did not do so in one patient with neonatal hepatitis. In contrast, oral vitamin D did not increase serum 25-OHD concentrations in patients with biliary atresia. It is concluded that the reduction of serum 25-OHD seen in biliary atresia was largely due to the malabsorption of vitamin D, while in neonatal hepatitis it was due to impairment of 25-hydroxylation of the vitamin.

A patient is presented who developed a granulomatous hepatitis and pleuritis approximately 7 months after an ileal bypass procedure for morbid obesity. Although the etiological agent was presumed to be Mycobacterium tuberculosis no pathogenic organism was grown from the liver, pleura, bone marrow, sputum, or gastric aspirate. The possibly increased susceptibility of these patients to mycobacterial infections is discussed. The value of obtaining serum levels of ethambutol, isoniazid, and rifampin, in patients with malabsorption is stressed. Although this patient seemed to respond to antituberculous therapy, other possible causes for the granulomatous process are explored.

A permature male infant required intravenous alimentation for six weeks following extensive surgery for ileal and cecal necrosis. At 3 months he developed evidence of hepatitis. Subsequently osteoporosis and the Fanconi syndrome appeared. Urine phosphate clearance was 83 percent of creatinine clearance at a serum phosphate concentration of 1.6 mg/dl. Concentration of plasma immunoreactive parathyroid hormone was elevated at 550 pg/ml. 25-Hydroxycholecalciferol was given at 240 mug/day. Aminoaciduria disappeared and bone healing occurred. Serum phosphate rose to 6.5 mg/dl and phosphate clearance fell to 2 percent of creatinine clearance. Upon cessation of 25-OHCC therapy, the Fanconi syndrome recurred despite administration of vitamin D2. 25-OHCC was then administered at 40 mug/day, and the urine abnormalities were reversed. The patient probably developed hyperparathyroidism, secondary malabsorption, and hepatitis. The Fanconi syndrome was the consequence of the hyperparathyroidism. 25-OHCC therapy was more effective than vitamin D in reversing the disordered state, possibly because of impaired hepatic metabolism of vitamin D2.

Many parasitic opportunistic infections occur in AIDS patients. In a young female drug abuser, HIV-positive at the IV stage, a microsporidian was detected and identified in urine by cell culture in fibroblast monolayers (MRC-5) and formally recognized by electron microscopy. This parasite has been involved in hepatitis, myositis and malabsorption syndromes in AIDS patients. Its diagnosis is difficult and this is the first time that its replication has been reported in human diploid cells in vitro.

The alpha 1-antitrypsin deficient subject (protease inhibitor (PI) phenotype ZZ) has an increased susceptibility to liver disease. The condition is most commonly identified in early infancy as a conjugated hyperbilirubinaemia with hepatitis (11%) or a bleeding state due to vitamin K malabsorption (2%). 50% of cases have cirrhosis and 25% die in the first decade of life. A further 2% present with cirrhosis in later childhood. Adult males are at risk of hepatoma development with or without cirrhosis. Diagnosis is by isoelectric focussing or allele-specific oligonucleotide hybridization. The treatment is that of cholestasis and cirrhosis including transplantation. The pathobiology of the deficiency state, the mechanism of liver damage and the vulnerability of the newborn liver are discussed in this review. A plea is made for a trial of infusions of alpha 1-antitrypsin in early infancy, as is used safely but without proven efficacy in the emphysematous PIZZ subject. Prospects of therapy by gene modification are also reviewed.

To define the clinical picture and course of the autosomal recessive disease called autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), we report data from our 10-month to 31-year follow-up of 68 patients from 54 families, now 10 months to 53 years of age. The clinical manifestations varied greatly and included from one to eight disease components, 63 percent of the patients having three to five of them. The initial manifestation was oral candidiasis in 41 patients (60 percent), intestinal malabsorption in 6 (9 percent), and keratopathy in 2 (3 percent). All the patients had candidiasis at some time. The earliest endocrine component appeared at 19 months to 35 years of age. Hypoparathyroidism was present in 54 patients (79 percent), adrenocortical failure in 49 (72 percent), and gonadal failure in 15 (60 percent) of the female patients greater than or equal to 13 years of age and 4 (14 percent) of the male patients greater than or equal to 16 years of age. There were multiple endocrine deficiencies in half the patients. From 4 to 29 percent of the patients had periodic malabsorption, gastric parietal-cell atrophy, hepatitis, alopecia, vitiligo, or a combination of these conditions. Dental-enamel hypoplasia and keratopathy were also frequent but were not attributable to hypoparathyroidism. In the patients whose initial manifestation (other than candidiasis) was adrenal failure, the other components developed less often than in the remaining patients. We conclude that the clinical spectrum in patients with APECED is broad. The majority of patients have three to five manifestations, some of which may not appear until the fifth decade. Therefore, all patients need lifelong follow-up for the detection of new components of the disease.

After reviewing recent data concerning the pathologic physiology of cystic fibrosis the authors present an anatomoclinical study of 30 infants, of which 13 neonates, with a diagnosis of mucoviscidosiss, emphasizing the clinical and pathohistologic polymorphism of this affection, and, particularly involvement of the liver and intestines. Specific hepatic lesions were encountered in only 10% of the group studied (Bodian biliary cirrhosis and mucus stoppers in the bile ducts). Unspecific hepatic lesions were dominant, common with those of neonatal hepatitis, and hepatic steatosis. Stress is laid on the presence of atrophy of the villi in children with hepatic steatosis, proof of a lesional substrate of malabsorption in this disease. The authors note the early onset of hepatic lesions, the gravity of the cases with an early clinical expression and hepatic biopsy puncture as the only method revealing hepatic affection in cystic fibrosis. In the first semester of life there exists purely digestive forms, hepatic steatosis and oedematous dystrophy in infants at this age being highly suspect of the etiology.

Subjects with a variety of enteropathies, hemolytic anemias, acute respiratory distress syndrome, hepatitis, Gaucher's disease as well as those on TPN and hemodialysis, often have low ("deficient") blood levels of vitamin E. A deficiency of vitamin E can be manifested by accelerated red blood cell destruction and neuromuscular deficit. Supplementation of these patients may be advisable. Neurological dysfunction has been observed in adults with prolonged vitamin E deficiency resulting from lipid malabsorption. Long-term treatment with high doses of vitamin E results in improvement. Administration of 800 IU/day of vitamin E to subjects with G6PD deficiency, sickle-cell anemia and beta-thalassemia has resulted in improvement of hematological parameters. Supplementation with 300 IU/day for 3-6 months has resulted in improved walking distances and improved blood flow in patients with intermittent claudication. In a limited number of controlled studies, 300-600 IU/day resulted in improvement in premenstrual syndrome, tardive dyskinesia and also arthritis. Epidemiological studies suggest that high levels of serum vitamin E are associated with lower risk of certain cancers, cardiovascular disease and infections. In some cases the high levels are difficult to obtain by diet alone. High levels of vitamin E are contraindicated in subjects who are receiving vitamin K antagonists as anticoagulant therapy. Except for this interaction with vitamin K, there are no specific side effects associated with high doses of vitamin E. Thus, there are various reasons for supplementations with vitamin E and, with the exception noted, the risk of such supplementation is very low.
