Subacute thyroiditis is generally thought to be a self-limited inflammatory disease of the thyroid gland. This paper describes serial observations on the clinical course of a typical patient with subacute thyroiditis. This patient showed specific features of destructive thyrotoxicosis with increases in the serum levels of acute phase reactants and in the erythrocyte sedimentation rate. She also showed signs of liver dysfunction [slightly increased alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (gamma-GTP), and leucine aminopeptidase (LAP)], slight anemia, glucose intolerance, increased pancreatic enzymes, splenomegaly, and an increase in peripheral Leu 7 positive (NK/K) cells. These abnormalities all improved with recovery from disease. These findings indicate that in this patient with subacute thyroiditis inflammation is not limited to the thyroid gland but also involves the liver, pancreas and spleen. Thus the subacute thyroiditis in this patient may be a systemic multi-organ disease.

The cholesterol and phospholipid content and the fatty acid composition in plasma and red cell membranes was determined in 10 alcoholics with macrocytic erythrocytes. None of the patients had anemia. Red cells exhibited macrocytosis up to 108 fl in all patients. Bilirubin, albumin, prothrombin, and cholinesterase were in the normal range, whereas transaminases and gamma-glutamyl transpeptidase activities in serum were elevated in most of the patients. The molar ratio cholesterol/phospholipids in red cells was not altered in alcoholics. An abnormally high ratio of saturated/unsaturated fatty acids was found in plasma as well as in red cell phospholipids from alcoholics. Linoleic acid was substantially decreased in plasma of alcoholics (controls 32.3%, alcoholics 21.8%). This fatty acid abnormality was reflected by a decrease of linoleic acid in red cell phosphatidylcholine. The present data may suggest that fatty acid changes taking place in membranes of macrocytes were a consequence of changes in the plasma and reflect plasma/membrane exchanges rather than direct effects of ethanol on red cell membranes. Lipid alterations of red cell membranes may be involved in the development of macrocytosis in chronic alcoholism.

A 69-year-old Japanese female was admitted because of general fatigue. Laboratory data showed elevation of serum total bilirubin, transaminase, gamma-glutamyl transpeptidase, and creatinine levels. An immunological study revealed hypergammaglobulinemia, low titer of complement, and high titers of antinuclear antibody, anti-DNA antibody, and circulating immune complexes. Antibodies to parainfluenza virus 3 were positive. Histology of the liver disclosed numerous giant cell hepatocyte transformations with the lobular architecture being slightly distorted by portal inflammation and fibrosis. These findings led us to make a diagnosis of giant cell hepatitis associated with systemic lupus erythematosus. Prednisolone was effective in improving the anemia and the serum immunoglobulin, immune complex, and antinuclear antibody levels. The addition of cyclosporine to the initial corticosteroid therapy was also beneficial in decreasing the transaminase level and in improving liver histology. The patient died of acute pneumonitis and renal failure on the 166th day after admission. Parainfluenza virus 3 and autoimmune mechanisms were thus considered to be the causes of the giant cell hepatitis.

Following the subchronic intoxication of rats with phenylhydrazine, resulting in marked anemia, reticulocytosis, methemoglobinemia and increased hemocatheresis, the hepatic content of total iron was increased, as was hepatic ferritin and its saturation by iron. A striking increase (approximately 7-fold) was also observed in free iron which appeared to be redox-active. The increase in liver free iron involved the hepatocellular component of the liver. Since DNA is one of the cellular targets of redox active iron, liver DNA from phenylhydrazine-treated rats was analyzed by electrophoresis and found to be markedly fragmented. Experiments with isolated hepatocytes in culture or in suspension challenged with phenylhydrazine or Fe-nitrilotriacetate strongly suggested that the DNA damage was due to reactive iron rather than to the hepatic metabolism of phenylhydrazine. The levels of 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo), a specific marker of oxidative DNA damage, were significantly higher in phenylhydrazine-treated rats as compared to untreated controls. The prolongation of phenylhydrazine treatment over a period of 6 weeks resulted in a persistent damage to DNA and in phenotypic changes such as an increase in hepatocyte gamma-glutamyl transpeptidase (gamma-GT, EC 2.3.2.2) activity. Possible relationships between iron overload, iron release, DNA damage and tumor initiation are discussed.

Following intravenous inoculation with horse blood-infected with the agent of human granulocytic ehrlichiosis (HGE) from a human fatality, two rhesus macaques (Macaca mulatta) exhibited pyrexia and lethargy on days 4-12 postinfection (PI). Hematology revealed neutropenia, thrombocytopenia, and anemia, with ehrlichial morulae in monocytes and neutrophils on days 4-12. Blood was polymerase chain reaction (PCR)-positive on days 4-12 and bone marrow was PCR-positive on day 11. There was a minor increase in gamma-glutamyl transpeptidase on day 12 and serum interferon-gamma levels increased by day 18. Seroconversion occurred on day 20 PI to a titer of 100 by day 22. Western blot bands characteristic of HGE included 25-, 44-, 80-, 94-, 105-, and 125-kD bands. There was generalized lymphohistiocytic infiltration in the liver, spleen, lymph nodes, and other tissues. The liver had focal hepatocyte apoptosis. There was HGE DNA (by PCR) only in the spleen. Comparable findings were not observed in a monkey that received uninfected horse blood as a control. This animal model of human disease is important for further studies of HGE diagnosis, management, and pathogenesis.

Rosai-Dorfman disease (RDD) is a rare histiocytic proliferative disorder with massive lymphadenopathy. We here describe RDD of a neonate who presented with paleness and hepatosplenomegaly but not lymph-node swelling. Routine laboratory studies showed anemia, thrombocytopenia, and an elevated value of gamma-glutamyl transpeptidase. Histological examination of the liver revealed a proliferation of histiocytes with abundant eosinophilic cytoplasm, which were positive for S-100 protein and CD68 but not CD1a and did not reveal Birbeck granules. Radiological studies showed hepatosplenomegaly and a narrowing of the hepatic vein, which might have contributed to hypersplenism resulting in anemia and thrombocytopenia. This case is thought to be congenital RDD without lymphadenopathy.

A 12 y old girl was admitted 24 days after start a WHO multidrug therapy scheme for multibacillary leprosy (dapsone, clofazimine and rifampicin) with intense jaundice, generalized lymphadenopathy, hepatoesplenomegaly, oral erosions, conjunctivitis, morbiliform rash and edema of face, ankles and hands. The main laboratory data on admission included: hemoglobin, 8.4 g/dL; WBC, 15,710 cells/mm3; platelet count, 100,000 cells/mm3; INR = 1.49; increased serum levels of aspartate and alanine aminotransferases, gamma-glutamyl transpeptidase, alkaline phosphatase, direct and indirect bilirubin. Following, the clinical conditions had deteriorated, developing exfoliative dermatitis, shock, generalized edema, acute renal and hepatic failure, pancytopenia, intestinal bleeding, pneumonia, urinary tract infection and bacteremia, needing adrenergic drugs, replacement of fluids and blood product components, and antibiotics. Ten days after admission she started to improve, and was discharged to home at day 39th, after start new supervised treatment for leprosy with clofazimine and rifampicin, without adverse effects. This presentation fulfils the criteria for the diagnosis of dapsone hypersensitivity syndrome (fever, generalized lymphadenopathy, exfoliative rash, anemia and liver involvement with mixed hepatocellular and cholestatic features). Physicians, mainly in geographical areas with high prevalence rates of leprosy, should be aware to this severe, and probably not so rare, hypersensitivity reaction to dapsone.

Erythrograms determined from whole blood analyses and serum analyses for aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT) and alkaline phosphatase (ALP) activities, and iron concentration, were used in infected and uninfected cattle to determine the type of anaemia and degree of hepatic damage caused by Fasciola hepatica. Blood samples from 86 infected and 30 uninfected cattle were taken at slaughter. Haematological analyses revealed decreased levels of packed cell volume (PCV), haemoglobin concentration, mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) in infected compared with uninfected cattle (P < 0.05). A decrease in the concentration of serum iron was also observed in infected cattle compared with uninfected cattle (P < 0.05). Significant increases in AST, GGT and ALP activities were observed in cattle infected with F. hepatica when compared with uninfected cattle (P < 0.05). It was concluded that the anaemia observed in cattle infected with F. hepatica is a normocytic, hypochromic anaemia and the most important aetiology of the anaemia is the chronic blood loss due to the blood-sucking activity of the adult flukes and leakage of blood from the bile duct to the intestine, which results in iron deficiency. The increased activities of serum enzymes indicated chronic hepatic and bile duct injuries associated with chronic infection with F. hepatica.

The primary objective of this phase I study of LY2780301, a dual p70 S6 kinase and Akt inhibitor, was to determine the recommended phase II dose as a single agent in patients with advanced cancer. Secondary objectives included safety, pharmacokinetic, and pharmacodynamic analyses, and co-clinical analyses in Avatar models. Eligible patients received total daily doses of LY2780301 100-500 mg, given orally as a single dose or divided into 2 doses for 28-day cycles. Dose escalation followed 3 + 3 design. The primary pharmacodynamic endpoint was inhibition of S6 assessed by skin and tumor biopsy. Thirty-two patients were treated. Common toxicities possibly related to treatment included constipation (19 %), fatigue (13 %), nausea (9 %), and diarrhea (9 %). Grade 3/4 toxicities potentially related to treatment were anemia (n = 2), increased alanine aminotransferase/aspartate aminotransferase (ALT) (n = 1), and increased gamma-glutamyl transpeptidase (GGT) (n = 1). One patient experienced best overall response of prolonged stable disease for 6 cycles. Plasma exposures of LY2780301 exceeded predicted efficacious exposures, but were not dose proportional. Among patients receiving 500 mg daily >50 % exhibited reduced S6 in skin biopsies at Day 8 of treatment, but the effect was not maintained. Plasma concentrations of LY2780301 and/or its metabolites were not correlated with S6 expression in the epidermis. There was minimal antitumor activity against the model, CRC 019. Avatar models showed minimal pharmacodynamic effects consistent with the observed antitumor effects. This study suggests a dose of LY2780301 500 mg QD for future studies.
