In this study, the author intended to examine the validity of the inhaled hydrogen gas clearance method (i-H2) for determination of the hepatic blood flow (HBF), and also to show some applicabilities of the method in experimental animals and patients with liver diseases. Simultaneous determinations of HBF by i-H2 and electromagnetic flowmetry in rabbits revealed an excellent correlation between the values obtained by the two methods. Moreover, HBF in rabbits measured by i-H2 varied in parallel with that by thermocouple flowmetry or laser Doppler velocimetry after administration of norepinephrine, propranolol or glucagon. In carbon tetrachloride-treated rats, HBF measured by i-H2 correlated better with the severity of damage in the sinusoidal structure than the severity of hepatic cell injury or the serum levels of transaminases. HBF as determined by i-H2 was significantly decreased in acute hepatitis (AH), chronic inactive hepatitis (CIH), chronic active hepatitis (CAH), liver cirrhosis (LC) and fatty liver. Reduced HBF in AH returned to normal during recovery of the disease. The ratio of HBF in tumor/normal tissue was greater than 1.0 for hepatocellular carcinoma in contrast to the ratio of less than 1.0 for metastatic liver carcinoma. Propranolol caused a decrease in HBF by 31%, and vasopressin by 39% in patients with CIH or LC. In contrast, glucagon induced its increase by 65%, 35% and 17%, respectively, in patients with CIH, AH and LC.

A case of brucellosis associated with peritonitis, intestinal obstruction, granulomatous hepatitis, inappropriate antidiuretic hormone (ADH) secretion and meningitis is reported. Initially, the patient was diagnosed as a case of disseminated tuberculosis and treated accordingly. However, the serologic tests for brucellosis were strongly positive and the patient was subsequently treated as a case of brucellosis and recovered fully. The gastrointestinal manifestations of brucellosis are reviewed.

A case of transient nephrogenic diabetes insipidus occurred in late pregnancy, the first associated with biopsy-proven hepatitis. Five previously reported cases occurred in pregnancy. All six patients demonstrated similar but transient signs, symptoms and laboratory abnormalities suggesting a syndrome peculiar to pregnancy. The characteristics of this syndrome are elevated liver function studies, decreased renal function, hyperuricemia and transient vasopressin-resistant diabetes insipidus.

The medical records of 31 immunocompromised patients who experienced varicella infections from 1975 to 1982 were reviewed. Fifteen of these patients had visceral involvement. In these 15 patients, two clinical patterns of progression were noted: (1) Eleven patients with life-threatening involvement experienced hepatitis (n = 11), pneumonitis (n = 11), abdominal pain (n = 11), encephalopathy (n = 10), coagulopathy (n = 10), inappropriate antidiuretic hormone (ADH) syndrome (n = 10), back pain or myalgia (n = 5), and myocarditis (n = 1). Seven of these patients survived, all without sequelae. (2) Four patients with a milder course experienced subclinical hepatitis (n = 4), mild pneumonitis (n = 4), postinfectious encephalitis (n = 1), and septic arthritis associated with disseminated intravascular coagulopathy (n = 1). All four of these patients recovered completely. In patients with severe involvement, intense abdominal pain was frequently the first sign of dissemination. Abdominal pain and inappropriate ADH syndrome were unexplained and have not been previously described in progressive varicella. A predictable pattern of organ involvement enabled starting therapy early and resulted in the survival of 11 of 15 patients.

The hepato-renal syndrome is defined as potentially reversible functional renal failure associated with acute fulminant hepatitis or, more often, with advanced chronic liver failure. It is characterized by oliguria, azotemia, retention of sodium and water with formation of ascites, and hyponatremia. While urinary sodium concentration of less than 10 mEq/l reflects intact tubular sodium absorption, the kidney lacks the ability for adequate free-water generation. This condition must be separated from specific renal diseases which may arise during the course of intra-or extrahepatic diseases and which must be classified accordingly. Pathophysiological aspects of the hepa-to-renal syndrome include hemodynamic factors, such as changes in intrarenal blood flow distribution in the presence of elevated intrarenal and reduced peripheral vascular resistance. The functional relationship of vasoconstrictor, sodium retaining, and anti-diuretic hormones (e.g., renin-angiotensin, aldosterone, and vasopressin) to vasodilator, diuretic, and natriuretic hormonal factors (e.g., prostaglandins, kinins, and natriuretic hormone) may be altered as well. Finally, a pre- and intrahepatic spillover resulting in decreased endotoxin clearance must be considered. Due to the lack of understanding of their complex interactions, so far pharmacological and therapeutic approaches remained ineffective to correct at least some of these factors. Today, recovery from hepato-renal syndrome will, therefore, mainly depend on the course of the underlying liver disease.

von Willebrand's disease (vWD) is the most frequent inherited disorder and is the result of a deficiency and/or abnormality of von Willebrand factor (vWF). As a consequence, the level of factor VIII, the presence of which reflects the ability of vWF to stabilise it, is usually low. Bleeding time, which reflects the ability of vWF to promote platelet adhesion to subendothelium, is therefore prolonged. However, from a therapeutic point of view, it appears that the correction of factor VIII and bleeding time is sufficient to prevent or treat bleeding in these patients. There are 2 main therapeutic tools to improve or normalise these major determinants of the bleeding tendency in this disorder. The majority of patients, identified by a test infusion, can be successfully treated by giving desmopressin (DDAVP), a synthetic analogue of vasopressin. Desmopressin is able to induce the increase of autologous vWF released from endothelial cells, leading to the correction of factor VIII levels and of bleeding time. In the remaining cases, blood products, namely factor/vWF concentrates, are required to accomplish haemostasis. All these concentrates are able to correct factor VIII levels, whereas their effect on bleeding time may not be consistent. The modern virucidal techniques abolish the risk of transmission of blood-borne viruses (e.g. hepatitis viruses and HIV) and make these products safer than blood-bank cryoprecipitate.

The mesenteric hemodynamic response to circulatory shock is characteristic and profound; this vasoconstrictive response disproportionately affects both the mesenteric organs and the organism as a whole. Vasoconstriction of post-capillary mesenteric venules and veins, mediated largely by the alpha-adrenergic receptors of the sympathetic nervous system, can effect an "autotransfusion" of up to 30% of the total circulating blood volume, supporting cardiac filling pressures ("preload"), and thereby sustaining cardiac output at virtually no cost in nutrient flow to the mesenteric organs. Under conditions of decreased cardiac output caused by cardiogenic or hypovolemic shock, selective vasoconstriction of the afferent mesenteric arterioles serves to sustain total systemic vascular resistance ("afterload"), thereby maintaining systemic arterial pressure and sustaining the perfusion of non-mesenteric organs at the expense of mesenteric organ perfusion (Cannon's "flight or fight" response). This markedly disproportionate response of the mesenteric resistance vessels is largely independent of the sympathetic nervous system and variably related to vasopressin, but mediated primarily by the renin-angiotensin axis. The extreme of this response can lead to gastric stress erosions, nonocclusive mesenteric ischemia, ischemic colitis, ischemic hepatitis, ischemic cholecystitis, and/or ischemic pancreatitis. Septic shock can produce decreased or increased mesenteric perfusion, but is characterized by an increased oxygen consumption that exceeds the capacity of mesenteric oxygen delivery, resulting in net ischemia and consequent tissue injury. Mesenteric organ injury from ischemia/reperfusion due to any form of shock can lead to a triggering of systemic inflammatory response syndrome, and ultimately to multiple organ dysfunction syndrome. The mesenteric vasculature is therefore a major target and a primary determinant of the systemic response to circulatory shock.

To find the incidence, markers and nature of complications of typhoid fever, we studied 102 children with cultures positive for Salmonella typhi in a cross-sectional study, prospectively, over a period of almost 5 years. All isolates were sensitive to commonly used antibiotics. One third of these children developed complications which included: anicteric hepatitis, bone marrow suppression, paralytic ileus, myocarditis, psychosis, cholecystitis, osteomyelitis, peritonitis, pneumonia, haemolysis, and syndrome of inappropriate release of antidiuretic hormone (SIADH). Twelve children developed multiple complications. If hepatitis is excluded from the complications, the rate of complications in bacteriologically confirmed cases of typhoid fever drops to 11 per cent. These complications were not related to: the age or sex of patients, duration of illness before admission, use of antibiotics before admission, nutritional status, level of 'O' or 'H' titre, presence of IgM or IgG antibodies, or treatment with chloramphenicol or ampicillin. Children with splenomegaly, thrombocytopenia or leukopenia were more likely to develop complications.

A hematopoietic stem cell transplant recipient developed abdominal pain, pneumatosis intestinalis, hepatitis, pancreatitis, and inappropriate antidiuretic hormone secretion. Blood for varicella-zoster virus (VZV) DNA polymerase chain reaction was positive. She was treated with acyclovir and subsequently developed VZV antigen-positive zoster. Detection of VZV DNA in blood may be useful for early diagnosis in immunocompromised hosts who present with zoster without skin lesions.

A recalcitrant rheumatoid arthritis patient taking low dose weekly methotrexate was given oral 2-chlorodeoxyadenosine (cladribine) for 8 months in a multicenter trial. He developed dual infections over the course of the trial: disseminated herpes zoster and staphylococcal arthritis of the right elbow. His disseminated herpes zoster started with severe, unremitting abdominal pain caused by a gastric ulcer, followed by disseminated cutaneous herpes, hepatitis, pancreatitis, encephalitis, homonymous hemianopsia, the syndrome of inappropriate secretion of antidiuretic hormone (ADH), and malabsorption. Both the herpes zoster and S. aureus infections required prolonged proper chemotherapies. Serious, complicated viral, bacterial, or other unusual infections should be considered in patients with severe rheumatoid conditions treated with combination immunosuppressive therapy.
