רקע: בשנים האחרונות גדל והולך בבתי-החולים בישראל השימוש בכפפות לטקס, בעקבות עלייה ניכרת בשיעור המחלות הזיהומיות המועברות דרך דם והפרשות, כגון דלקת כבד מסוג B ו-C ומחלת האיידס. אולם השימוש הגובר בכפפות לטקס וגומי גרם לעלייה במספר מקרי האלרגיה ללטקס בין עובדי מערכת הבריאות. בשני סקרים שנערכו לאחרונה בישראל בבית חולים כללי ובבית חולים לילדים, נמצאה שכיחות נמוכה של אלרגיה ללטקס.

מטרה: לבדוק שיעור אלרגיה ללטקס בין עובדי בית חולים כללי בישראל החשפוים למגע עם כפפות לטקס.

שיטות: נכללו במחקר 203  עובדים של מרכז רפואי רמב"ם, ממחלקות שבהן יש שימוש רב בכפפות לטקס. כל עובד ענה בשאלון על פרטים דמוגרפיים, פרטים הקשורים למחלקתו ולפקידו, אנאמנזה אישית ומשפחתית על אלרגיות ופרטים קליניים הקשורים לחשיפה לכפפות לטקס. דגימות-דם ניטלו מכל הנכללים במחקר למטרת בדיקה כמותית של נוגדן IgE כללי ושל נוגדן IgE סגולי ללטקס, שנבדק בשיטת DPC Alastat-ELISA.

תוצאות: 75 מבין 203 העובדים (36.9%) הצהירו על תופעות קליניות העלולות להיות קשורות לחשיפה ללטקס. רק 32 עובדים (15.8%) הצביעו על תופעות קליניות שניתן ליחסן לתגובת רגישות-יתר מיידית (אלרגיה מטיפוס I), כגון נזלת, התעטשויות, דמעת והפרעות-נשימה, בקרב 30 מהם (המהווים 14.8% מכלל העובדים) נמצאו נוגדני IgE סגוליים ללטקס (מעל 0.35 יב"ל/מ"ל), וב-21 מהם (המהווים 10.3% מכלל העובדים) נמצאו רמות גבוהות מאוד של IgE סגולי ללטקס (1.5 יב"ל/מ"ל). כמחצית מהעובדים (43.4%) עם נוגדני IgE סגוליים ללטקס היו רופאים והשאר אחיות (23.3%), עובדי משק (20.0%) ועובדי מעבדה (13.3%). המאפיינים המשמעותיים ביותר בקרב 30 עובדים עם אלרגיה ללטקס מטיפוץ I היו אנאמנזה אישית ומשפחתית של אלרגיה, רמות גבוהות של IgE כללי וחשיפה ללטקס מעל שעתיים ביום.

מסקנות: היארעות תגובת יתר של רגישות מיידית ללטקס בקרב עובדי בית חולים כללי בישראל (14.8%) דומה לזו שנמצאה במרכזים רפואיים אחרים בעולם. עובדים עם אנאמנזה אישית או משפחתית של אלרגיה, החשופים ללטקס מעל שעתיים ביום ושבדמם נמצאה רמה גבוהה של IgEכללי, היו בסיכון גבוה ללקות בתופעות קליניות של אלרגיה ללטקס מטיפוס I. על סמך נתונים אלה, ניתן לאתר עובדים במערכת הבריאות שיש למנוע את המשך חשיפתם ללטקס, על-מנת למנוע או להפחית התהוות תופעות קליניות הקשורות באלרגיה ללטקס.

Introduction of Routine Hepatitis Immunization in Israel 

Emilia Anis, Alex Leventhal, Malvina Roitman, Paul E. Slater 

Notification of hepatitis A, which is endemic in Israel, has been compulsory since the establishment of the State. From 1992-98 an average of 2,600 cases were reported annually. Many infections are asymptomatic and mild, especially in children. In general, severity increases with age; in Western countries the case fatality rate is 1.5/1,000 among children less than 5 years old and 27/1,000 among those over 50. Until 1987 incidence in Israel was higher in Jews than in non-Jews, but since 1988 incidence has been about 50% higher in non-Jews.

Among Jews highest age specific rates shifted from children 1-4 years old to children 5-9 years old in 1970, and in non-Jews in 1989. Improved sanitary conditions and personal hygiene have reduced very early childhood exposure and hence increased the proportion of susceptible older children and adults, in whom symptomatic disease is more prevalent.

Israel is the first country in the world to include hepatitis A vaccine in its routine immunization schedule. The vaccine is given in 2 doses: at 18 months and 24-30 months of age, and there will be epidemiologic and serologic follow-up. A significant decrease in hepatitis A morbidity is expected in small children within 5 years. The percentage of reported cases in older children and in adults is expected to increase, although the absolute incidence among these groups will decrease.

Acquired infection with hepatitis C virus (HCV) in hemodialysis patients has been described lately. In dialysis units in Italy and France, the prevalence and incidence of HCV are 20-60% and 1-2%, respectively. Most infected patients develop chronic hepatitis. The clinical presentation of acute HCV in hemodialysis patients is very mild and therefore the diagnosis is often made only by laboratory tests. Acute infection is usually followed by mild elevation of liver enzymes and the presence of HCV-RNA and anti-HCV in serum.

We report a 48-year-old man on hemodialysis who developed acute hepatitis C. The diagnosis was made by finding mild elevation of liver enzymes and the presence of HCV-RNA in his serum. A few months later, he developed severe hepatitis which was followed by rapid deterioration in liver function. However, the virus was eradicated and liver function tests became normal. Surprisingly, serum anti-HCV antibodies were detected 5 months later.

Does Incidence of Hepatitis AIncrease During Shmitah (The Sabbatical Year)?

In Israel the biblical injunction of the sabbatical year (shmitah) prevails, whereby all Jewish-owned land should lie fallow during every seventh year. Consequently, it is customary for members of the orthodox Jewish community to eat only produce grown by non-Jews (Arabs). Many Arab farmers use sewage water for irrigation and since such water could be infected with hepatitis A virus (HAV), there is concern about the possibility of HAV epidemics during the sabbatical year.

We therefore we examined the data of the Israeli Center for Disease Control (ICDC). We found no obvious increase in incidence of viral hepatitis during, nor in the year immediately after, all sabbatical years since 1951. However, the data was not comprehensive as it included only partial information on morbidity from HAV in our Jewish inhabitants. Also, there was no data specific for the orthodox Jewish community, which is especially at risk for HAV from sewage-irrigated vegetables. Irrespective of shmitah, there should be constant effort to prevent HAV infection in Israel.

Prevalence of hepatitis G virus (HGV) infection in the general western population ranges from 0.2-1.5%. In high-risk groups, such as patients with chronic liver disease, hematologic disorders and drug addicts, prevalence is as high as 10%-15%. Dialysis patients have increased rates of HGV infection (6%-50%).

We evaluated prevalence of HGV infection among dialysis patients, and the association between HGV infection and hepatitis C virus (HCV) infection. Serum samples were screened for HGV infection by RT-PCR. Screening for HCV infection was performed by an EIA test and confirmed by RIBA and RT-PCR for HCV. Sera were also tested for HBV markers.

The study group included all 78 hemodialysis patients and 7 of the 12 peritoneal dialysis patients in our unit during September to November 1997. 4 (5.2%) were HGV-positive but none were peritoneal dialysis patients. 1 of the 12 HCV-positives was also infected with HGV. HGV infection was not associated with duration of dialysis, number of blood transfusions or levels of transaminases.

Prevalence of HGV infection among our hemodialysis patients was low (5.2%), but higher than reported for the general population. Prevalence of HGV/HCV infection in hemodialysis patients was low and unrelated to duration of dialysis, number of blood transfusions and levels of transaminases.

Is Official Data on Reported Morbidity Valid? Hepatitis A in Israel as an Example

Hepatitis A is one of the most frequently reported notifiable infectious diseases in Israel. The annual incidence as reported is around 70/100,000. The physician or the diagnostic laboratory notifies the district health office of the Ministry of Health.

The purpose of this research was to evaluate the sensitivity of passive surveillance of hepatitis A morbidity among adults, 18 years and over. Methods included study of notifications to the Ministry of Health or hospitalizations of cases of hepatitis A and of positive laboratory tests results (IgM) for hepatitis A. We estimated the extent of under-reporting by 2 different methods of extrapolation.

Data based on passive surveillance among the adult population, between 1.1.1993-31.12.1994, comprised less than 1/5 of the actual number of cases. Physicians notified about 6.2% of their hepatitis A patients. 5.1% of the notifications to the district health office were sent twice or more, usually both by the physicians and labs.

The official data on hepatitis A morbidity, based on passive surveillance, are considerably underestimated. Physicians and public health officials should be aware that such data may not accurately reflect the magnitude of the risk or the amount of disease that can be prevented. Efforts should be made to improve this situation.

Guillain-Barre and other neurologic syndromes rarely occur as complications of viral hepatitis (A, B and C). Other neurologic syndromes have also been reported in serologically defined viral hepatitis, including mononeuritis, auditory neuritis, and seizures. Chronic hepatitis B and mononeuritis multiplex are found together in 31-54% of patients with periarteritis nodosa. The mechanisms of these associations are unknown, but may include direct cytotoxicity of the virus or immune-mediated damage. Vasculitis of the vasa nervorum plays an intermediate role, at least in some cases. We describe a 36-year-old man with acute non A-G hepatitis complicated by Guillain-Barre syndrome. The neurological manifestation resolved completely without specific therapy within 6 days, as the hepatitis resolved.

Results of laboratory tests ordered during a primary care encounter may reveal findings of abnormal liver function tests, including elevated liver enzymes, hyperbilirubinemia, hypoalbuminemia or abnormal coagulation tests. The object of this study was to describe the spectrum of these liver function test (LFT) abnormalities in primary care.

Results of all laboratory tests ordered during 10 months in an urban primary care clinic were retrospectively reviewed and the medical charts of patients with abnormal LFTs were studied. In 217/1088 (20%) of the tests at least 1 LFT abnormality was found in 156 patients. New diagnoses were made in 104 patients. The main diagnostic groups were: non-alcoholic fatty liver changes, Gilbert's disease, acute infectious hepatitis, alcoholic liver disease and cirrhosis and hepatotoxic drug injury. In 60 patients the physician classified the abnormality as negligible and not associated with significant disease. However, an abnormal test that had been ordered for evaluation of a specific complaint, was indeed likely to represent significant disease (X²=29.5, p<0.001). We conclude that finding abnormalities in liver function tests is common in the primary care clinic but does not often indicate significant liver disease.

Our experience with living-related liver transplantation is described. In 2 boys and 1 girl, aged 4-4.5 years with acute, fulminating hepatitis A, the presence of very severe jaundice (bilirubin levels > 18 mg%) associated with severe coagulopathy (INR>10) and encephalopathy indicated the need for urgent liver transplantation. In all 3 cases the left lateral hepatic segment of a matched blood type parent was transplanted. None of the donors suffered a serious complication postoperatively and all returned to full activity in 6-16 weeks. The post-transplantation course was uneventful in 1 child, but in the other 2 there was hepatic arterial thrombosis in 1 at 1 day and in the other at 8 days post-transplantation. Early detection of arterial thrombosis by Doppler sonography permitted salvage of the 2 hepatic grafts after thrombectomy and re-anastomosis. In 1 of these 2 children an anastomotic biliary stricture was found 2 months after transplantation. It was corrected at surgery and a percutaneous stent was inserted. All 3 children are alive with normal graft function at 2, 7 and 8 months post-transplantation, respectively. This initial experience indicates that living-related liver transplantation is feasible in Israel. The technique might help to solve our severe organ shortage for children awaiting liver transplantation.

Health care workers are at continuous risk of hepatitis B infection. Currently recommended intramuscular vaccination confers immunity in only 85-90%. We examined the immunogenicity and safety of intradermal vaccination of hepatitis B vaccine in nonresponders. 400 hospital employees who had been immunized as recommended were screened for anti-HBs antibodies and 50 were found seronegative. Each received an intramuscular booster injection and antibody level was measured a month later. Excluded were 33 employees, including 24 late responders, 2 HbsAg carriers and 7 uncooperative employees. 17 employees (mean age 47.1 yrs) then received a series of 3 intradermal injections of Energix B, 0.25 ml in the forearm, 2-3 weeks apart. The mean number of previous intramuscular injections was 4.6±1.4 month later there was a mean titer of 315.4±347.0 miu/ml of antibody in 16/17 workers. Side effects were minimal. Intradermal injection of hepatitis B vaccine for nonresponders seems effective for inducing seroconversion. Its cost-effectiveness for the health care system warrants assessment.

Ischemic hepatitis can occur as an acute episode in advanced congestive heart failure (CHF). The mechanism is massive necrosis of the central lobules resulting from acute hypoxia when low cardiac output further reduces oxygen supply, aggravating underlying congestion due to poor venous outflow. We describe a 70-year-old woman with congestive heart failure for 7 years who was admitted with jaundice, vomiting, abdominal pain and oliguria after an episode of hypotension. The diagnosis of ischemic hepatitis was established by a documented episode of severe hypotension, followed by elevation of serum transaminases, a rise in serum bilirubin and LDH levels, prolonged prothrombin time and acute renal failure. Other causes of acute hepatitis, such as a virus or drugs were excluded, and improved liver and renal function followed hemodynamic stabilization. We conclude that ischemic hepatitis should be considered whenever acute hepatitis follows a recent episode of systemic hypotension, especially in the context of concomitant CHF.

Disappointing Response of Chronic C Hepatitis to Interferon

From February 1990 to August 1995 we treated 58 patients with chronic hepatitis C using alfa-interferon, 3 million units 3 times weekly for 6 months. Of the 48 patients with adequate follow-up, 34 did not respond to treatment at all. 10 patients responded, but within a few months hepatic enzymes again increased. These 2 groups can be considered failures of interferon treatment. In 4 patients enzymes remained normal for the duration of follow-up, (10-34 months). Even in this small group, 1 patient had a positive test for HCV RNA after completion of treatment. A partial explanation of our disappointing results may be the high prevalence of a subtype of C hepatitis-subtype 1b, which has recently been reported in Israel. This strain is particularly resistant to interferon. The means to define subtypes were not, and as far as we know are not yet available in Israel. Various groups have attempted to improve the outcome of treatment of hepatitis C, which in other hands too was still far from satisfactory. Thus, regimens of interferon utilizing higher doses and longer periods of treatment are being evaluated, as well as the addition of Ribavirin, which hopefully will improve results.
