One hundred seventy-eight newborns were cultured for cytomegalovirus (CMV) on admission and weekly after 4 weeks of age until discharge. Eight (all with birth weights of 1050 g or less) acquired CMV while hospitalized. At least seven of the infected infants were born to CMV-seronegative mothers. The risk for seronegative infants weighing less than 1250 g of acquiring CMV was 24%. There was no correlation between duration of hospitalization and birth weight for infants hospitalized over 30 days. There was a significant correlation (P less than 0.0001) between the number of blood donors for an infant and the acquisition of CMV. Infected infants received blood from eight or more donors prior to CMV shedding. Infected low birth weight infants received blood from an average of 6.5 CMV antibody-positive donors, while uninfected low birth weight infants received blood from an average of 3.1 CMV antibody-positive donors. No infant received nonmaternal breast milk. After acquiring CMV, three infants died (only one was autopsied and had proved disseminated CMV disease), two developed hepatitis and one developed hepatosplenomegaly. These results suggest that acquired CMV infection is a significant risk to seronegative low birth weight infants who receive blood from seropositive blood donors.

Histiocytic medullary reticulosis (HMR) was originally defined as a neoplastic disorder. Some cases reported as HMR have been characterized by a systemic proliferation of mature histiocytes showing hemophagocytosis, bone marrow necrosis, pancytopenia, hepatitis, and coagulopathy. Clinically, these patients have fever and constitutional symptoms and often have hepatosplenomegaly and lymphadenopathy. Although there is a high mortality rate, this process appears to be reactive and has been associated with active viral infection. Similar cases have been briefly described that were associated with other agents or disease processes, but concomitant viral infections were not excluded. Three characteristic examples of this hemophagocytic syndrome that were associated with bacterial sepsis are described. Active infection by those viruses that have previously been associated with the syndrome was excluded. It appears that the hemophagocytic syndrome may be associated with various types of active disseminated infections.

Multiorgan, abnormalities in dialysis patients (for example, hepatosplenomegaly, granulomatous hepatitis, cytopenia from hypersplenism) have recently been ascribed to the loading of macrophages (MO) with silicone particles released from the pump segment of dialysis tubing. In the present study, the effect of chronic intravenous or intraperitoneal loading of rats with silicone, polyvinylchloride (PVC) and polyurethane (PU) particles on arachidonic acid metabolism of peritoneal MO and splenic cells was examined in vitro. Intravenous injections of silicone, PVC, or PU particles caused accumulation of the material within the lysosomes of MO of spleen, liver, and lung. Spontaneous release of prostaglandin E2 (PGE2) and thromboxane B2 (TXB2) was significantly increased in peritoneal MO of rats injected with silicone, PVC, or PU (Control: 4.27 +/- 0.85 ng PGE2/ml/24 hr; silicone 51.9 +/- 13.2; PVC 57.5 +/- 10.6; PU 28.8 +/- 2.3). Zymosan or LPS stimulated PGE2 release from control MO, but caused no consistent further elevation of high basal PGE2 release from MO after particle loading. Furthermore, increased spontaneous and stimulated TXB2 release was also observed in spleen cells of rats given intravenous injection of silicone particles. It is concluded that storage of plastic particles (silicone, PVC, and PU) by macrophages stimulates arachidonic acid metabolism.

We postulated that three tests could be used to advantage in the prognosis of patients with alcoholic liver disease. Ninety-eight patients who entered the hospital in hepatic failure, and who survived that illness, were observed for an average of 3.5 years after discharge. At the time of entry, most had jaundice, ascites, edema, and hepatosplenomegaly. Biopsy of the liver disclosed both cirrhosis and hepatitis in 75-80%. Neither clinical features nor laboratory tests could differentiate these patients at the time of entry. However, as early as 3 months after hospitalization, the clinical course and laboratory tests served to distinguish two groups: group 1 comprised 46 patients in whom the serum bilirubin was less than 2 mg/dl; the aspartate aminotransferase less than 55 mU/ml; and the alkaline phosphatase less than 125 mU/ml. In 40 (87%) of these 46 patients, clinical findings improved concomitantly with laboratory tests. Group 2 comprised 52 patients in whom one or more of these three tests showed persistent abnormality; only 12 (23%) of the 52 patients in this group improved clinically and three subsequently died. Although the majority of patients (76%) in group 1 reported abstinence on follow-up, 44% of group 2 patients also claimed abstinence. Complications of liver disease, shunt surgery, and continuing alcoholism contributed to liver failure. Early identification of such patients should aid in the management of alcoholic liver disease.

A Japanese boy, who was born to an asymptomatic HBsAg and HBeAg carrier mother, developed acute type B hepatitis at age 6 months. Hepatosplenomegaly and abnormal liver function tests persisted. Liver biopsy at 10 months showed giant cell hepatitis with cirrhosis. He was given alternate-day therapy with prednisolone for 7 months. HBsAg was detectable from ages 6 to 19 months, but not after. Anti-HBs and anti-HBe were not present at any time.

The diagnosis and management of childhood visceral leishmaniasis were studied in 51 parasitologically proven cases from Abha, Saudi Arabia. Bone marrow aspiration was positive in 40 of 47 cases (85%). Splenic aspiration, though rarely used because of perceived dangers, was not associated with complications and revealed the parasite in all 12 cases in which it was used. There was prompt response to sodium stibogluconate, with defervescence in 93% and decrease of hepatosplenomegaly in 67% of patients within 1 week of commencing chemotherapy. A dose of 20 mg/kg/day for at least 3 weeks was generally safe and effective in achieving cure and preventing relapse. Two children with persistent massive splenomegaly after the first course responded to prolonged chemotherapy. Bronchopneumonia and severe cytopenia were common complications. Disseminated intravascular coagulation and hepatitis were associated with a poor outcome. The four patients who died had a progressive course with multiple complications. Early detection and appropriate management of complications may help to reduce morbidity and mortality in childhood visceral leishmaniasis.

We report here on two patients with kidney allografts who had hepatitis and duodenal ulcer caused by cytomegalovirus. In one case, hepatosplenomegaly and jaundice appeared after high fever lasting for ten days. Laboratory examinations showed liver dysfunction and lymphocytosis with atypical forms. Virological studies revealed cytomegalovirus infection and we successfully treated the patient with human interferon-beta. In the other case, duodenal bleeding followed by interstitial pneumonia occurred at the 54th day after transplantation. Bleeding from the small duodenal ulcer did not stop in spite of conservative and endoscopic therapies, and gastrectomy was performed. Histologically many epithelial cells with intranuclear inclusions were found around the ulcer. Virological studies showed elevation of antibody titres to cytomegalovirus which was isolated from the urine and oropharyngeal secrete. After gastrectomy and treatment with ganciclovir, the general condition improved and graft function was maintained. Our experience with these cases suggests that aggressive diagnostic investigations for cytomegalovirus infection are essential in patients with organ allografts who present liver and gastrointestinal lesions.

A three-month old Chinese male infant was a victim of neonatal hepatitis presenting with prolonged jaundice, poor body weight gain, progressive hepatosplenomegaly and extremely elevated serum alpha-fetoprotein level. Niemann-Pick disease (NPD) type C was confirmed by autopsy, which revealed sphingolmyelin deposition in multiple visceral organs, and normal sphingomyelinase activity in liver. This is the first case of NPD type C in Taiwan. In idiopathic neonatal hepatitis with hepatosplenomegaly here, NPD type C must be taken into consideration.

Mononucleosis is defined as atypical lymphocyte proliferation which causes clinical symptoms such as tonsillitis, lymphadenopathy, or hepatosplenomegaly. Mononucleosis syndrome is caused by cytomegalovirus (CMV), Toxoplasma, hepatitis virus, adenovirus, or other agents as well as by Epstein-Barr virus. The syndrome is immunologically characterized by the proliferation of activated T cells (HLA-DR+ T cells). We encountered three infants with hepatosplenomegaly who were diagnosed as primary CMV infection by the detection of anti-CMV IgM antibody. Although the patients were otherwise asymptomatic, analysis of lymphocyte subpopulations showed a decreased ratio of CD4+ to CD8+ T cells and augmented expression of HLA-DR antigen on T cells characteristic of infectious mononucleosis. We conclude that inapparent CMV disease may affect the immunologic status of infected children even if it is asymptomatic.

The records of 52 children with Niemann-Pick disease type C were reviewed to establish whether the disease process and outcome varied with the initial clinical pattern; 34 children (65%) had cholestatic liver disease and hepatosplenomegaly in infancy; 18 were seen at a mean age of 4 years with splenomegaly or neurologic disease or both. Of the 34 children with early cholestatic liver disease, three died in the neonatal period; cholestasis and hepatomegaly subsided in the remaining 31 children, although splenomegaly persisted. Of these 31 children, 15 had persistent liver disease with elevated aminotransferase values. Serial liver biopsy specimens showed that 3 of the 15 children had normal architecture and 12 had hepatic fibrosis, with progression to cirrhosis in 5. No other significant morbidity or additional deaths were associated with the liver disease. The clinical importance of persistent liver disease was overshadowed by the subsequent development of severe neurologic disease. There was no difference in the age at onset of the disease (mean, 4.5 years) or in the pattern of neurologic disease, including supranuclear ophthalmoplegia, whether or not the child had early liver disease. Overt neurologic disease has not yet developed in seven surviving children with liver disease at onset. Sixty-seven percent of children died during the study; the main cause of death was bronchopneumonia. We conclude that the diagnosis of Niemann-Pick disease type C should be considered in patients with unexplained neonatal hepatitis, especially if splenomegaly is a persistent feature. Because liver biopsy specimens may not demonstrate storage cells, bone marrow aspiration to detect the characteristic storage cells is recommended in such patients.
