    Notes: Summary Elastase 1 and immunoreactive trypsin were assessed by a RIA technique in the sera of 29 control subjects, 24 pancreatic cancer patients, 22 patients with chronic pancreatitis and 31 with extra-pancreatic diseases to ascertain and compare their usefulness in chronic pancreatic disease diagnosis. Increased levels of elastase 1 were detected in 60.9% of pancreatic cancer and in 61.1% of chronic pancreatitis patients; low values were found in only two subjects with pancreatic disease. A close correlation between the two enzymes was found in patients suffering from pancreatic cancer and chronic pancreatitis. These data suggest that serum elastase 1, as well as immunoreactive trypsin, is of limited value in chronic pancreatic disease diagnosis; increased levels of the two enzymes always occur simultaneously; low immunoreactive trypsin values together with normal elastase 1 serum levels are detectable in a number of patients with chronic pancreatitis and severe exocrine insufficiency.

    Notes: Summary The pancreolauryl test was performed in 30 subjects with chronic pancreatitis, in order to evaluate its behavior in relation to the duration of the clinical history and the presence of pancreatic calcifications, diabetes mellitus, jaundice, and pancreatic pseudocysts. A significant inverse linear correlation was found between the onset of symptoms and FDL test values. While calcifications and diabetes were present in patients with both normal and abnormal test results, those with pseudocysts or jaundice always had pathological results.

    Notes: Abstract Abstract A long-term follow up was begun in 1982 on offspring of mothers who acquired toxoplasmosis during gestation. The 114 newborns were subdivided into 3 groups: (1) 26 born to mothers with certain infection; (2) 51 born to mothers with probable infection, and (3) 37 born to mothers with doubtful infection. There were five infections in the first group (19.2%), three in the second (5.8%) and none in the third. For purposes of data elaboration we considered only the 77 offspring of mothers with certain or probable infection. Of these, 2 infected cases out of 52 (3.8%) were born to mothers with infection in the first trimester of pregnancy, 4 out of 21 (19%) in the second trimester, and two out of four in the third. There were a total of 8 congenital infections (10.4%). Specific IgM antibodies were revealed in five out of eight infected children (62.5%). Infection was symptomatic in two children (2.6% of newborns at risk, 25% of infected cases), both born to mothers with infection in the second trimester. In the other six cases diagnosis was reached by evaluating trends in antibody levels: the percentage of infected newborns was higher in the group of maternal infections untreated (50%) or improperly treated (15.4%), compared to those receiving adequate treatment (6.9%). We suggest considering as infected children presenting specific IgM antibodies and/or antibody titres which do not become negative, even when symptoms are absent. Therapy with spiramycin should be started in all newborns at risk, while the use of sulphamides and pyrimethamine is justified only after the presence of infection is confirmed. Conclusion Identification of susceptible women before or early in pregnancy would permit adoption of preventive measures aimed at reducing the frequency of congenital infection which is still high in our case series.

    Notes: With the aim of morphologically characterizing chronic sialoadenitis in patients with hepatitis C virus (HCV) chronic liver disease, labial salivary gland biopsies from 22 chronic HCV liver disease and from 10 primary Sjögren's syndrome patients were compared. Only focus score (number of aggregates with more than 50 lymphocytes per 4 mm2 of glandular tissue) and grading of inflammation were able to discriminate significantly between the two patient groups. Duct ectasia, acinar depletion, presence of lymphoid aggregates with less than 50 lymphocytes and of lymphoid infiltration within intralobular salivary duct epithelium were evident in both disease groups and appeared to be non-specific, mostly age-related changes. In both patient groups plasma cell and lymphocyte typing showed similar features: T lymphocytes represented most of the lymphoid population, B lymphocytes were few unless follicles were present. Higher focus score values were associated with a plasma cell switch from an IgA to an IgM and/or IgG predominance. A greater morphological similarity was seen between biopsies of the primary Sjögren's syndrome group and those of female rather than male chronic HCV liver disease patients. Salivary gland tissue in HCV patients responds to damage in a fashion similar to primary Sjögren's syndrome, the only difference being a lesser degree of inflammation.

    Description / Table of Contents: Zusammenfassung Ziel der Stude war es, zu prüfen, ob die Anwesenheit von Antikörpern gegen das HCV-Hüllprotein ein Marker für das Auftreten einer Leberschädigung ist, wie jüngst vorgeschlagen wurde. Sera von 104 Patienten (62 Männer, 42 Frauen) wurden untersucht: in einem Enzymimmunoassay der zweiten Generation waren 84 Patienten positiv und 20 negativ für anti-HCV-Antikörper; 51 Patienten hatten eine leichte chronische Lebererkrankung (44 chronische Hepatitis, 7 Fettleber), 43 eine Leberzirrhose (davon 18 bei hepatozellulärem Karzinom) und 10 waren asymptomatisch anti-HCV-positiv bei normalen Leberfunktionstests. Zusätzlich wurden alle Sera auf Antikörper gegen das synthetische Peptid S24A (SIYPGHVSGH RMAWDMMMNW SPTA), das sich aus der Aminosäuresequenz (307–330) des HCV-Polyproteins ableitet, mit Hilfe eines Enzymimmunoassays getestet. Anti-S24A-Antikörper fanden sich im Serum von 39 der 84 anti-HCV-positiven und in einem der 20 anti-HCV-negativen Patienten (Pearsonx 2 11,71, p〈0,001). Bei den anti-HCV-positiven Patienten ergab sich keine signifikante Differenz im anti-S24A-Status in Abhängigkeit von klinischen Anzeichen einer Lebererkrankung, von der ALT-Konzentration oder von der HCV-RNA-Positivität. Somit sind anti-S24A-Antikörper zwar in ungefähr der Hälfte der HCV-positiven Sera nachweisbar, aber sie scheinen weder zusätzliche, signifikante klinische Information gegenüber bekannten Tests zu liefern, noch scheinen sie sich als denkbarer Virämie-Marker zu eignen.
    Notes: Summary Our aim was to verify whether the presence of antibodies to HCV envelope protein might mark the occurrence of liver damage, as recently suggested in the literature. Sera from 104 patients (62 male, 42 female) were tested: 84 were positive and 20 were negative to a second generation enzyme immunoassay for anti-HCV antibodies; 51 patients had mild chronic liver disease (44 chronic hepatitis, seven steatosis), 43 had liver cirrhosis (superimposed by hepatocellular carcinoma in 18) and ten were asymptomatic anti-HCV positive subjects with normal liver function tests. Besides, all sera were tested by means of an enzyme immunoassay for the presence of serum antibodies to the synthetic peptide S24A (SIYPGHVSGH RMAWDMMMNW SPTA) derived from amino acids 307–330 of HCV polyprotein. Anti-S24A antibodies were detected in 40/84 sera positive and 1/20 negative at anti-HCV testing (Pearsonx 2 12.29; p=0.005). Among anti-HCV positive sera, no significant difference existed in anti-S24A status with regard to clinical evidence of liver disease, ALT concentration or HCV RNA positivity. Thus, anti-S24A antibodies are detectable in approximately half of HCV-positive sera, but they do not seem to add significant clinical information to existing tests or to be useful as putative markers of viraemia.
