Epidemiology of Crohn's disease in Zagreb, Yugoslavia: a ten-year prospective study.

A ten-year prospective study of Crohn's disease was carried out in Zagreb, Yugoslavia. It included both inpatients and outpatients regardless of the extent and severity of the disease. The mean annual incidence rate was 0.7 per 100,000 between 1 January 1980 and 31 December 1989. There was no increase in the incidence of Crohn's disease during the study period. The prevalence of Crohn's disease was 8.3 per 100,000 on 31 December 1989. The results confirm the low frequency of Crohn's disease in central and southern Europe.

Ulcerative colitis in Zagreb, Yugoslavia: incidence and prevalence 1980-1989.

We present a ten-year incidence of ulcerative colitis in Zagreb, Yugoslavia. The study included both outpatients and inpatients regardless of the extent and severity of the disease. The mean annual incidence rate was 1.5 per 100,000 inhabitants for the period of 1 January 1980 through 31 December 1989. There was no increase in the incidence of ulcerative colitis during the study period. A prevalence rate estimate of 21.4 per 100,000 inhabitants was based on July 1985 official estimated population. The results confirm the low frequency of ulcerative colitis in central Europe.

[Serum acute phase proteins for determining disease activity of ulcerative colitis and Crohn disease].

We studied the activity assessment of ulcerative colitis and Crohn's disease by 5 acute phase reactants: C-reactive protein (CRP), alpha 1-acid glycoprotein, alpha 1 antitrypsin, haptoglobin and fibrinogen. From a large register of patients with inflammatory bowel disease (IBD) we chose randomly 91 patients: 61 with ulcerative colitis and 30 with Crohn's disease. As a reference point in the disease activity assessment we used standard clinical indices. Statistical analysis was performed by non-parametric methods: the Kruskal-Wallis and Fisher's exact test. The disease activity assessment in patients with ulcerative colitis by the index according to Powell-Tuck indicated that the patients with active disease (N = 19) had significantly higher levels of all acute phase proteins mentioned above except fibrinogen (alpha less than 0.05 to 0.001) than patients in remission (N = 42). Analysis of the same data by Fisher's exact test indicated that there had been a probability for all the proteins measured to be higher than the normal values, particullary CRP (p less than 10(-8) and the other somewhat less. In patients with Crohn's disease, the disease activity assessment was performed by 2 indices. According to "The Crohn's Disease Activity Index" (CDAI), only alpha-1 acid glycoprotein and haptoglobin (alpha less than 0.05) were higher in patients with active disease (N = 4) than in patients with remission (N = 26).(ABSTRACT TRUNCATED AT 250 WORDS)

[N-acetyl-beta-D-glucosaminidase as an early marker and indicator of the extent of kidney and liver lesions in endotoxemia and endotoxic shock].

The aim of the study was to answer the question whether the serum level and the urine level of N-acetyl-beta-D-glucosaminidase (NAG) could be the indicator of liver and kidney lesions, and the indicator of the stage of the lesions, in cases of endotoxemia and endotoxin shock. The authors performed the experiment using 60 rabbits as experimental animals. The animals were divided into six groups (10 rabbits in each group); control animals received an equal volume (1.0 ml/kg of body weight) of physiological saline solution. Endotoxin (Lipopolysaccharide E. coli 055 B-5) in doses of 20, 40, 60, 80, and 100 micrograms/kg of body weight were administered in a single intravenous injection to each animal of I-V experimental groups. Using endotoxin in that dose of application, the authors provoked different stages of endotoxemia on the rabbits in the first four experimental groups, and the endotoxin shock on the rabbits of the fifth experimental group. After 18 hours, the rabbits were decapitated, and the levels of NAG in serum, urine, kidney and liver tissues determined. The results showed that the serum increase of NAG activity is caused not only by the lesions of kidney parenchyma, but by the lesions of liver parenchyma too, in the cases of endotoxemia and endotoxin-produced shock; the increase is statistically significant. Urine increase of NAG activity is significant even in cases in which the authors administered very low doses of endotoxin (20 micrograms/kg of body weight), so it can be said that urine NAG activity is a very good indicator of early kidney parenchyma lesions. But, the urine increase of NAG activity is (absolutely) in correlation with the dose of administered endotoxin, so it can be said that urine activity of NAG is the indicator of stage of kidney lesions in cases of endotoxemia and endotoxin-provoked shock.

Acute liver failure induced by carbamazepine.

Two children developed acute liver failure while taking carbamazepine. Clinical and laboratory findings suggested an immunoallergic reaction, but only one child improved on steroids. Determination of liver function during the first few weeks of treatment and early detection of signs of idiosyncrasy may prevent this rare but severe complication.

Prognosis of chronic granulomatous disease.

The records of 28 patients with chronic granulomatous disease born over a 32 year period were reviewed. The characteristics of the group, and the frequency with which various clinical and laboratory features had been recorded, was assessed. Nine patients were known to have died, in most cases of progressive suppurative infection. Actuarial analysis showed 50% survival through the third decade of life. The long term survival of patients developing symptoms after the end of the first year of life was significantly better than that of patients whose illness started in infancy. Our data confirm that the severity of chronic granulomatous disease is not uniform, and that the prognosis for long term survival is better than that suggested in earlier reports. Early onset may be a poor prognostic sign and invasive aspergillosis is a life threatening complication. In the absence of curative treatment, trials to assess the effectiveness of interferon gamma are necessary and early antenatal diagnosis should be offered to as many affected families as possible.

Relationship between tissue and serum concentrations of carcinoembryonic antigen (CEA) in gastric and colonic carcinomas.

A relationship between tissue and serum concentrations of carcinoembryonic antigen (CEA) as determined by monoclonal enzymo-immunoassay (EIA) was studied in 47 patients with gastric carcinoma and 46 patients with colorectal carcinoma. The values were then compared to those obtained in a control group of 64 healthy subjects. On the basis of results, an increase in tissue CEA is not paralleled by a simultaneous increase in serum CEA. Serum CEA depends on tumor mass and points to the process extension. There is no specific tissue CEA threshold above which the serum CEA concentration should unavoidably increase. A relationship between tissue and serum CEA concentrations according to the degree of differentiation, studied in colorectal carcinomas, revealed significantly lower values of tissue CEA concentration in poorly differentiated carcinomas, whereas serum CEA concentrations did not show any such difference. The present study has suggested that, having identified both tissue and serum CEA concentrations in colorectal carcinoma, the tumor, its size and differentiation could be readily and quite closely defined at the time of measurements.

[Dynamics of occurrence and mortality in colorectal carcinoma in the community around Osijek].

The extent and dynamics of the occurrence of colorectal carcinoma were analysed in all the communes of the region of Osijek during the period from 1968 to 1982. The age and sex of patients, geographical distribution and other factors which might have influenced the colorectal carcinoma occurrence were taken into consideration. The dynamic of the occurrence of colorectal carcinoma was analysed by the method of regression. The incidence of the carcinoma of the large bowel in the region of Osijek in 1982 was between 10.3% and 33.7% per 100,000 inhabitants. In most communes the incidence was between 20.9% and 28.1%. During the period from 1968 to 1982 there was an increase in the occurrence of colorectal carcinoma in all communes, with the exception of the commune of Slavonska Orahovica which is one of the most undeveloped areas in the region. A significant increase of the new cases of colorectal carcinoma was recorded in the communes of Beli Manastir and highly significant increase in the communes of Djakovo, Podravska Slatina, Slavonska Pozega and Vukovar. During the same period there was an evident increase in the mortality rate from colorectal carcinoma in all the communes in the region of Osijek. The rate was 22.2% per 100,000 inhabitants which represents 1.9% of overall mortality or 11.6% of the mortality from all malignant diseases in the region. With regard to epidemiological data and the authors' own investigations it has become obvious that more care and attention should be paid to the prevention of colorectal carcinoma as an integral part of the chronic disease prevention programme.

[The role of and suitability of the occult fecal blood test in a preventive program for colorectal carcinoma].

There are no final attitudes towards the necessity of the colorectal carcinoma screening in the population. The aim of this examination was to assess the motivation, applicability, sensibility and value of the occult faecal blood tests as the screening method in the colorectal carcinoma detection, as well as the analysis of the costs and the possibilities of testing within the regular health service. The testing of the occult faecal blood was offered to a random sample of 11.431 subjects. The tests were returned by 7.592 (81.9%) of the high-risk and by 1.690 (77.8%) of the control group testees. In the high-risk group (over 40 years of age) the positive test of the occult faecal blood was found in 1.09% of the examined patients and the colon carcinoma was established in 13 testees with the positive test (19.66%) or in 0.17% of the cases. The total costs per patient with a detected carcinoma were Din. 349.246. - what is 24.4% less than the price of a palliative operation. Colon adenoma was established in 16 testees of the high-risk group (0.21%). Colon adenoma and carcinoma were established in 34.94% of the testees with positive tests. Radical surgeries were made in 8 out of 10 operated testees. In the control group (20-40 years of age) two adenomas were established and no malignant disease. The test sensitivity was evaluated based on the colon carcinoma detection and it was 72.2% in Hemoccult-negative subjects up to two years after the testing.(ABSTRACT TRUNCATED AT 250 WORDS)

[Tissue carcinoembryonic antigen: a screening test for increased cell proliferation?].

A relationship between the tissue and serum concentrations of carcinoembryonic antigen (CEA) as determined by the enzymoimmunoassay (EIA) was studied in 46 patients with colorectal carcinoma and 47 patients with gastric carcinoma. The values were then compared to those obtained in the control group of 64 healthy subjects. Serum CEA concentrations were measured in all of them, whereas tissue CEA concentration was determined in the rectal and gastric mucosa homogenates in 30 and 34 subjects, respectively. As expected, no differences were observed in the levels of serum CEA concentrations in either of the healthy subject subgroups. The serum CEA concentrations were found to be at the normal level of 2.5 ng/ml. In both subgroups of healthy subjects, the tissue CEA concentration was found to significantly differ, but the same was in colorectal and gastric carcinomas as compared to the normal rectal and gastric mucosa. When the process extent according to Dukes' classification in 22 patients with colorectal carcinoma operated on was compared to the relationship between the tissue and serum CEA concentrations, the serum CEA concentration of CEA was shown to depend on the tumor mass, regardless of the level of the specific tissue CEA concentration. Unusually high values of tissue CEA concentration, along with normal serum CEA concentration, were observed in 3 healthy subjects. A relationship between the tissue and serum CEA concentrations according to the degree of differentiation, studied in colorectal carcinomas, revealed significantly lower values of tissue CEA concentration in poorly differentiated carcinomas (P less than 0.01), whereas serum CEA concentrations did not show any such difference.

Chronic persistent hepatitis. Long-term prospective study on the natural course of the disease.

Ninety-nine patients with chronic persistent hepatitis were followed up in a prospective study for an average of 6.7 years. Fifty-six patients had positive HBV markers; 29 of these patients had persistent HBs antigenemia, and 4 had persistent HBe antigenemia. No patient developed chronic active hepatitis or cirrhosis of the liver. It can be concluded that chronic persistent hepatitis is a benign non-progressive disease that does not require therapy.

Changes in serum phosphorus, calcium and alkaline phosphatase due to sucralfate.

We report on the results of the clinical trial, where the effects of sucralfate on the serum phosphorus, calcium and alkaline phosphatase in 30 patients with chronic renal failure on intermittent hemodialysis were examined. After 14 days of treatment with sucralfate (1 gram four times daily), we found a significant reduction in serum phosphorus and alkaline phosphatase and an increase in serum calcium. On the basis of its proven hypophosphatemic and ulcer-healing effects, sucralfate can be recommended in treatment of hyperphosphatemia and secondary hyperparathyroidism in chronic renal failure. Serum phosphorus should be checked routinely in patients treated with sucralfate for the peptic ulcer disease.
