Plasma glucose and lactate concentrations and glutamate-pyruvate transaminase (SGPT), glutamate-oxalacetic transaminase (SGOT), alkaline phosphatase (AP), aldolase (ALD), creatine phosphokinase (CPK), and hydroxybutyrate dehydrogenase (HBD) activities were determined before, throughout the incubation period, and during the course of a viral-induced diarrhea in the neonatal calf. Hypoglycemia with a glucose concentration less than 40 mg/dl of plasma was observed in 3 of 10 calves. Plasma lactate concentration increased to 1.84 plus or minus 0.1 times normal in 7 and 6 to 7 times normal in 2 of the animals. The major change in both glucose and lactate concentrations during diarrhea occurred during the 24 hours preceding death. Changes in SGPT, SGOT, or AP activities were not observed, indicating the absence of marked hepatic damage. The ALD, CPK, and HBD activities were increased in 2 calves and the CPK alone was increased in 2 others, indicating cardiac and possibly skeletal muscle damage.

Lysinuric protein intolerance (LPI), an autosomal recessive defect of diamino acid transport, is characterized chemically by renal hyperdiaminoaciduria, especially lysinuria, and by impaired formation of urea with hyperammonemia after protein ingestion. Our 20 patients thrived during breast-feeding, but ingestion of cow's milk caused diarrhea and vomiting. When able to select their diet, they rejected all protein-rich foods. They were short staturated and had weak atrophic muscles, osteoporosis, hepatomegaly and often splenomegaly. Four patients were mentally retarded. Fifteen patients had leukocyte counts below 4,000/mm3, and 17 patients had platelet counts below 150,000/mm3. Serum lactate dehydrogenase activity was constantly increased, and transaminase and aldolase activities were often increased. In the infants' livers, changes were only revealed by electron microscopy: increased and vesicular smooth endoplasmic reticulum, and abundance of glycogen particles in the hepatocytes. In the older patients, light microscopy demonstrated clearly limited areas where hepatocytes had large pale cytoplasm and small pyknotic nuclei. The diamino acids lysine, arginine and ornithine had plasma concentrations only one-third to one-half the normal mean; the renal clearances were clearly increased. Oral diamino acid loading tests suggested impaired intestinal absorption. Urea is built in the liver through transformation of ornithine to arginine, and cleavage of arginine to ornithine and urea. The addition of ornithine to an intravenous I-alanine loading prevented the hyperammonemia and normalized the urea production. Therefore, the diet has been supplemented with arginine, and more protein has been added. This therapy has lead to a remarkable catch-up growth in some patients. The pathophysiology of LPI is explained. Because of defective intestinal absorption and incrased renal loss, the diamino acids have a low plasma concentration. Their transport from plasma to hepatocytes is also impaired, and the liver becomes deficient in ornithine. This retards the urea cycle, and leads to postprandial hyperammonemia and protein aversion. The presence of the transport defect in the hepatocytes distinguishes LPI from other hyperdibasicaminoacidurias.

A 70-year-old man was admitted to our hospital because of fever and progressive dyspnea in December 1989. He was already diagnosed as having erythrocytosis secondary to pulmonary fibrosis 4 years previously and the values of his hematocrit (Ht) were maintained between 44.5 and 62.9% by repeated phlebotomy. Immediately after admission, severe diarrhea developed and the Ht value was 61.5%. Around 1:30 a.m. of the 3rd hospital day, he developed disturbance of consciousness. In addition, the serum levels of LDH, CPK, aldolase, and myoglobin of muscle origin increased markedly and the Ht value showed 78.5%. While the level of consciousness was gradually restored by 600 ml phlebotomy and 1,500 ml saline infusion, dysarthria and hemiplegia became evident. The Ht value early in the morning of the 3rd hospital day was reduced to 59.4%. Although cranial CT and MRI performed 74 days and 15 months, respectively, after the onset of the symptoms failed to reveal any abnormal shadow, he was clinically suspected to have cerebral infarction. These findings emphasize that abrupt increase in Ht or blood viscosity is a possible factor triggering cerebral infarction, and adequate control of Ht value is recommended for the prevention of such a condition in the aged.

Generalized komuragaeri disease (Satoyoshi disease) is a rare disorder of unknown etiology, characterized by painful muscle spasms, alopecia, diarrhea and various endocrine disorders. We administered glucocorticoid to a girl with this disease, resulting in a marked improvement of all clinical features. The patient was a 15-year-old girl. Since the age of 13 years, she had had intermittent painful muscle spasms, which affected any skeletal muscles 5 to 15 times a day at exercise and at rest and lasted for a few minutes. At the age of 14 years, she had idiopathic thrombocytopenic purpura which responded to the glucocorticoid treatment. Amenorrhea and orthostatic hypotension developed at the age of 14 years. Then the loss of body and head hair was noticed and progressed slowly. She had not experienced severe diarrhea. On admission, her physical and neurological examinations showed no abnormalities except for the thin hair and frequent muscle spasms. Laboratory examinations showed elevated levels of serum creatine kinase and aldolase, positive antinuclear antibody of speckled pattern and a mild disturbance in carbohydrate absorption. Endocrinological tests suggested the dysfunction of hypothalamus as a cause of amenorrhea. Electromyogram showed large action potentials on spasms. She was treated with glucocorticoid, 2 mg/kg on alternate days. The muscle spasms decreased gradually in frequency and duration in 1 month of treatment, and disappeared in 4 months. The growth of her hair was noticed and orthostatic hypotension disappeared in 4 months. Menstruation became regular in 7 months. The muscle spasms worsened when the dosage of glucocorticoid was reduced, and they improved on the increased dosage. She was free of symptoms at 6 months after the successful diminution of glucocorticoid. The etiology of this disease has not been revealed. The association of autoimmune disorders and the responsiveness of all clinical features to glucocorticoid suggest that an autoimmune process is involved in the pathogenesis of generalized komuragaeri disease.

Four patients had trichinosis after consuming raw home-butchered pork. The patients had fever, myalgias, periorbital edema, and conjunctivitis. All of the patients had nausea, vomiting, or diarrhea (corresponding to the intestinal phase of the infection) seven to ten days before the onset of fever and myalgias. Laboratory findings included eosinophilia, elevated serum CPK and aldolase values, and seroconversion of Trichinella serology one month after onset of myalgias. The patients were treated with mebendazole and prednisone and recovered uneventfully.

Aldolase activity with the two substrates fructose-1-phosphate and fructose-1,6-diphosphate was measured in the homogenate of small intestinal biopsy specimens from children with different malabsorptive diseases (celiac disease, cow's milk protein intolerance, infectious diarrhea, giardiasis, and Crohn's disease) and controls. It is demonstrated that the ratio of fructose-1,6-diphosphate/fructose-1-phosphate activity, which reflects the relative amounts of the crypt enzyme aldolase A (EC 4.1.2.13) and the villous enzyme aldolase B (EC 4.1.2.7), correlates very well with both the ratio of crypt to villous height (correlation factor r = 0.92) and the mitotic index (r = 0.80).

A 22-year-old man developed transient unconsciousness during running. He developed fever, nausea, vomiting, diarrhea and general fatigue. Next day, he was admitted to National Hospital Nayoro because of high serum CK level of 13,610U/l. Biochemical analyses revealed elevated serum myoglobin, increased CK-MM isozyme, aldolase and lactate dehydrogenase, increased serum osmolality, increased uric acid, and decreased serum potassium levels. Therefore, he was diagnosed as having rhabdomyolysis. In addition, serum CK-MB isozyme, cardiac myosin light chain I and troponin T were increased, suggesting the damage of cardiac muscle. Electrocardiogram showed elevated ST segment and inverted T on V2-4, which were not observed previously. He had no preceding infectious disease, drug ingestion or an underlying metabolic disorder. The rhabdomyolysis may be precipitated by the superimposition of dehydration and loss of potassium due to diarrhea and vomiting. The myocardial injury, probably produced by transient myocardial ischemia, should be paid attention in case of rhabdomyolysis.

We encountered a case of psittacosis accompanied with rhabdomyolysis in a 66-year-old woman admitted to our hospital because of myalgia, fever, diarrhea, and disorientation. A chest CT scan showed air-space consolidation and ground-glass attenuation in the left lung. Laboratory findings showed elevation of CPK, myoglobin, and aldolase, consistent with rhabdomyolysis. She recovered after administration of intravenous erythromycin and steroid pulse therapy. Psittacosis was diagnosed from the history of exposure to pigeons and from elevation of the IgG titer for Chlamydia psittaci. Rhabdomyolysis is associated with some kinds of viral or bacterial infections. But few case reports have been found in the case of psittacosis. The mechanism whereby rhabdomyolysis complicates psittacosis is unknown. We suggest that psittacosis should be added to the list for differential diagnosis, when rhabdomyolysis develops in a patient with pneumonia.

The protozoan Giardia lamblia is a major cause of parasite-induced diarrhea in humans. Humoral immunity has been shown to be important for clearance of the infection, but only a few antigens have been identified. In this study, we focused on the immunoreactivity of nonvariant antigens. Serum samples from 93 patients with acute giardiasis who were infected during a waterborne outbreak in a nonendemic country were screened on 1-dimensional Western blots. Representative serum samples that reacted strongly with proteins of different molecular weights were further analyzed on 2-dimensional Western blots. Sixteen immunoreactive proteins were identified using mass spectrometry analysis, among them variable surface proteins, alpha-giardins, arginine deiminase, ornithine carbamoyl transferase, and fructose-1,6-bisphosphate aldolase. Several of the identified proteins were immunoreactive in recombinant form, and they may be important in the development of new diagnostic tools and vaccines.
