    ABSTRACT: Smoking cigarettes is very common among lactating women. The objective evaluation of an exposure to cigarette smoke is needed, as cotinine concentration. On many research a questionnaire is the only determinant of fact and intensification of smoking. The aim of this research was to establish a reliability of the questionnaire concerning cigarette smoking among lactating mothers by analyzing cotinine/creatinine ratio. Material and methods: In 51 lactating mothers (participants of the research on oxidative stress in Obstetrics Departments on 3rd day post partum) during check-up visit, on 30th day post partum a questionnaire concerning smoking cigarettes before, during pregnancy and after childbirth, and amount of cigarettes smoked was made. Samples of matutinal urine were deep freezed in - 700 till cotinine was evaluated immunoenzymatically. Women were divided into groups: I of non-smokers (32 women), II of smokers (19 women). Statistical analysis was made by means of unparametric test U Mann-Whitney. Results: Average cotinine/creatinine ratio was 33,8 ng/mg in group I; 1275.9 ng/mg in group II. Specificity and sensitivity of data earned by virtue of statement of correspondents was 81% and 89%. Test of cotinine concentration in urine demonstrated 100% sensitivity and 94% specificity compared to the cotinine/creatinine ratio. Directly proportional relationship was stated between amount of cigarette smoked and concentration of cotinine in urine (55.9 ng/ ml cotinine/cigarette). Conclusions: A questionnaire should not be the only method evaluating smoking among lactating women. The concentration of cotinine shows slightly lower specificity than cotinine/creatinine ratio. Both tests can be dealt equivalent.

    ABSTRACT: Transforming growth factor-beta1 (TGF-beta1) is known to play a key role in processes of cell proliferation and differentiation. It also plays an important role in modulation of the immune response. Various diseases may arise both from excessive and insufficient activity of this cytokine. THE AIM OF THE STUDY was to evaluate the role of TGF-beta1 in the pathogenesis of chronic hepatitis (Ch.h.) and to assess whether TGF-beta1 level in plasma or its tissue expression can be useful in diagnosing and monitoring of clinical course of this disease. Twenty-one children with chronic hepatitis were included in the study and 42 healthy children constituted the control group. Liver function tests and TGF-beta1 plasma levels measured by ELISA method were evaluated in both groups of patients. In liver tissue obtained by needle biopsy, the histopathological grading and staging of hepatitis was evaluated, TGF-beta1 protein was assessed by immunohistochemical methods and TGF-beta1 gene expression was measured by reverse transcription and real-time polymerase chain reaction. In chronic hepatitis group of patients the plasma TGF-beta1 level did not differ from the control group and did not correlate with grading and staging of the liver tissue while positive correlation was observed with gamma-glutamyl transpeptidase activity in the serum. There was no correlation between tissue TGF-beta1 expression and TGF-beta1 plasma level and staging or grading in liver tissue. TGF-beta1 gene expression correlated positively with ESR and ALAT activity but no correlation with TGF-beta1 plasma level, TGF-beta1 gene or protein expression, grading or staging in liver tissue were observed. 1. In children with chronic hepatitis, TGF-beta1 plasma level is not related to grading or staging in the liver tissue. This finding may be due to low level of fibrosis observed in the studied children. 2. It appears that local expression of TGF-beta1 in liver tissue should not be used as a sole marker in differentiating and monitoring the course of chronic hepatitis. 3. In children with chronic hepatitis assessment of liver TGF-beta1 gene expression is not helpful in the evaluation of pathological changes in liver tissue. 4. Due to the relatively low number of patients in the analysed groups it seems advisable to perform similar complex studies in larger groups of children with chronic hepatitis.

    ABSTRACT: The group of 96 strains ofEscherichia coli isolated from children with diarrhea were investigated towards the presence and polymorphism of genes encoding autotransporters that belong to the group of proteins named SPATE (Serine Protease Autotransporters ofEnterobacteriaceae). Based on the results of restriction analysis of the products of PCR reaction 8 different types of genes encoding SPATE were detected. It was found that 39 strains contained one gene of SPATE, 15 strains contained two different genes and 3 different genes were detected in the case of 3 strains. The analysis of combination of presence of genes encoding SPATE let us divide the investigated group of strains into 17 different genotypes. The analysis of polymorphism of genes encoding SPATE seems to be very promising tool for exploring the genetic diversity among pathogenic E. coli.

    ABSTRACT: Over one million people all over the world die every year due to the complications of HBV infections. This problem is particularly important in Asia, Africa and in the West Pacific region where HBV infection is widely spread (from 5-20% up to 80% of all infected people in the world). In these regions HBV infections are transmitted mostly perinatally or during early childhood. In North America and in West Europe where after introducing anti-HBV vaccinations less than 2% of the population is affected, infections are usually transmitted by intravenous drug abuse, sexual intercourse, or much less frequently by blood transfusions. The immaturity of immune system in young children is responsible for the fact that nearly 90% of HBV infections acquired in infancy and 40-70% of HBV infections before the age of 3 years, result in chronic viral hepatitis. Therefore, the choice of an efficient and safe therapy is one of the most important problems. In this paper current data concerning indications for treatment and side-effects of interferon-alpha and lamivudine therapy in children with chronic viral hepatitis type B are presented.

    ABSTRACT: Vasculitis is a group of rare diseases of unknown etiology, characterised by inflammation and necrosis of blood vessels, contributing to various clinical consequences. The variety of clinical symptoms and presence of symptoms from various syndromes often make the diagnosis difficult. Until now no causal treatment has been established. In order to achieve a remission of the disease, corticosteroids and immunosuppressive therapy are recommended.

    ABSTRACT: THE AIM OF THE STUDY was to evaluate the occurrence of HBV genotypes and the emergence of polymerase gene mutations in children with chronic hepatitis B in the course of the lamivudine therapy. eighteen children (aged from 6 to 15 years, mean age 11,8 years, 10 boys and 8 girls) with chronic hepatitis B were included in the study. All patients were treated with 100 mg lamivudine tablets given daily orally for 12-16 months. All amino acid substitutions within HBV polymerase were detected by PCR amplification and direct sequencing HBV genotypes and polymerase gene mutations were determined by comparing the sequences in the overlapping PollS genes with published sequences, available in GenBank. HBVgenotyping showed the presence of genotype A in 17 children and genotype H in one. No change of HBV genotype was noted in any of the studied patients as the sequencing of HBV DNA was repeated during the lamivudine therapy. The presence of lamivudine-resistance mutations involving the YMDD motif was detected in 5 patients. Four children had YVDD mutation, while in one child YIDD mutation was detected. YIDD mutation appeared to be the single one in the viral polymerase gene, while YVDD mutations in four patients were accompanied by other changes at amino acid sequence of the HBV polymerase: rtL180M, rtN124D and rtL164M. 1) Genotype A was predominant in the studied population of patients. 2) The risk of the emergence of drug-resistant HBV polymerase mutations is high and increases in the course of the lamivudine therapy. 3)Drug-resistant mutations in the YMDD motif are accompanied by other amino acid substitutions in the viral polymerase of unclear clinical significance.

    ABSTRACT: Parasitosis still remains a significant pediatric health problem, despite improving hygienic conditions and social awareness. was to analyze clinical manifestations of Giardia lamblia infection in children hospitalized in the Department of Pediatrics, Pediatric Gastroenterology and Oncology of Medical University of Gdansk. studied children included 49 patients aged 2.2 - 17.3 years: group I children below and group II above 5 years of age. The patients were admitted for further diagnosis of unexplained clinical manifestations in outpatient care. Parasitosis was confirmed by immuno-enzymatic technique detecting protein GSA 65; only in one child parasites cysts were found by microscopic technique in faecal samples obtained from infected children. chronic abdominal pain was noted in 16 (72.7%) children in group I and in 22 (81.5%) patients in group II. Chronic diarrhea was observed in 20 (90.9%) children in group I and in 4 (14.8%) in group II. Ultrasound scans revealed mesenteric lymphadenopathy in 42 children (16 in group I and 26 in group II). chronic and recurrent abdominal pain was the main clinical complain and chronic diarrhea in children under 5 years of age. In few cases hepatobiliary involvement was observed, which might suggest a changing clinical course of giardiasis. Most of the children presented with mesenteric lymphadenopathy, which was confirmed by abdominal ultrasound scan. Thus, this method should be included in the diagnostic algorithm, if parasitosis is considered.

    ABSTRACT: of this study was to analyze the clinical status of children with short bowel syndrome (SBS) shortly after the resection and during following years. we reviewed retrospectively 5 children with SBS aged from 2 years and 7 months till 14 years and 5 months, who were on total parenteral nutrition due to intestinal resection. The resection was performed, when they were either newborns or infants. In the analysis we considered somatic development and laboratory tests results. In 4 cases the cause for extensive bowel resection were congenital anomalies of the intestine, in one case it was intestinal necrosis as result of invagination. in all children there was diarrhea, during postoperative period and when oral caloric intake was increased and when loss of weight was observed. Most common complications included hypochromic anaemia and cholestasis. Moreover, in 2 children with resection of distal region of the ileum and ascending colon, we observed vitamin B12 deficiency and recurrent lactic acidosis due to secondary biotin deficiency. Catheter complications were one of the main problems. 3 patients developed sepsis. Occlusion or mechanic damage of the catheter were also observed. Despite initial severe retardation in somatic development, final anthropometric evaluation in all children was found to be normal. 1. Congenital intestinal and mesenteric defects were the most common reasons for SBS in the youngest children. 2. Parenteral nutrition is the cardinal element in the management. It was crucial for survival and further normal somatic development, even in children after extensive intestinal resection. 3. Lactic acidosis due to biotin deficiency must be considered if acid-base balance restoration is complicated in children with SBS. 4 Children with SBS after resection need long-term and multi specialistic medical care.

    ABSTRACT: of the study is to evaluate the reasons of mesenteric lymphadenopathy and its clinical picture in hospitalized children. the study was performed on 127 children (49 girls and 78 boys age of 8 months to 18 years; mean age 9 years and 3 months) hospitalized in the Department of Paediatrics, and Paediatric Gastroenterology and Oncology, Medical University of Gdansk. Ultrasonography showed enlarged abdominal lymph nodes in all children. According to definition of mesenteric lymphadenopathy, the clinical course of disease was analyzed in children, in whom there were at least three lymph nodes in ultrasonography with the peroneal diameter of 5 mm or more. Inflammatory parameters were examined in all children. In selected cases culture, viral and parasitic, as well as endoscopic examination, were also performed. analyzing accompanying clinical symptoms, it was found, that abdominal pain was the most dominant complaint in children with mesenteric lymphadenopathy; it was observed in 63 children (49.6%). In 33 (26%) of them the pain was the sole complaint, while in the rest vomiting and fever were present. 8 children (6.3%) with generalized lymphadenopathy were diagnosed. Ultrasonographic evaluation demonstrated that numerous enlarged lymph nodes were present the most frequently, in 65 (51.2%), less numerous, in 42 (33.1%), while sparse lymph nodes were seen only in 20 (15.7%) children. In 85 patients (66.9%) long axis of the lymph nodes reached min. 10 mm, in 39 (30.1%) was smaller than 10 mm, in 3 (2.4%) exceed 20 mm. Conglomerates of lymph nodes were described in 9 (7.1%) patients with various diagnosis (acute diarrhea - 3 children, ulcerative colitis - 3 children, celiac disease, cytomegaly, lambliosis). Tendency to invagination was observed in 5 (3.9%) children. In 4 of them acute infection (acute diarrhea, pneumonia) with high inflammatory parameters was diagnosed. Elevated inflammatory parameters were present in 42 (33.1%) patients. Examining the reasons of the abdominal lymph nodes enlargement, it was found that primary mesenteric lymphadenopathy was the most frequent diagnosis; it was recognized in 27 (21.3%) children. In 20 (15.7%) lymphadenopathy was caused by acute diarrhea, in 19 (14.9%) patients - by respiratory tract infection. Cytomegaly was recognized in 4 (3.1%), toxoplasmosis in 3 (2.3%), lambliosis in 9 (7.0%) patients. Both gastritis and colitis were diagnosed in 12 (9.4%) children. In 7 (5.5%) patients generalized lymphadenopathy with unknown etiology was described. In single cases other diseases were diagnosed. the enlargement of mesenteric lymph nodes frequently causes abdominal pain in children, being an indication for laboratory investigations. Vomiting and fever are the most common other symptoms in these patients. Ultrasonographic examination usually shows large enlargement of lymph nodes, sometimes in conglomerates, with tendency to invagination. Acute diarrhea and respiratory tract infection are the most frequent reasons of the enlargement of abdominal lymph nodes. In about 20% of the children primary mesenteric lymphadenopathy is diagnosed.

    ABSTRACT: Congenital extrahepatic biliary atresia (CEBA) is one of the most common causes of cholestasis in newborns and infants. was the analysis of clinical presentation, results of laboratory and imaging investigations as well as clinical outcome of children with extrahepatic cholestasis caused by CEBA. the analyzed group included 15 children aged from 2 weeks to 4 months. Data concerning: pregnancy and delivery, newborn's health condition, faeces color; jaundice onset, manifestation of coagulation disorders coexisting malformations and disorders of other systems were obtained. The following investigations were performed: biochemical tests evaluating the function of the liver and cholestasis (serum bilirubin concentration and fractions, bile acids in serum, AlAT, AspAT, GGTP, FALK activities, serum electrophoresis, prothrombin index). We also performed tests focusing on hepatotropic infections, - metabolic disorders tests and in all children - ultrasound of the abdomen, scintigraphy of the bile ducts - HEPIDA. 14 children had undergone hepatoportoenterostomy, modo Kasai. jaundice, acholic stools and hepatomegaly were present in all children. The serum concentration of bilirubin and its conjugated fraction and bile acids in all children were increased. GGTP and FALK activities were markedly elevated in all children. Aminotransferases activities elevations were observed, more distinctively for AST. Active cytomagalovirus infection was detected in 3 children. Abdominal ultrasound revealed gallbladder in 7 children, whereas intrahepatic bile ducts were described as normal in 12 cases. In all cases the HEPIDA scintigraphy showed no passage of the tracer to the GI tract even after 24 hours delay. Hepatoportoenterostomy was performed in 14 children, 5 of them had liver transplantation. 1. There is still not one effective and specific diagnostic method in differentiating between the causes of cholestasis in the newborns and infants. Thus many investigation methods should be run simultaneously. 2. Congenital atresia must be definitely excluded before cholestasis with other background is finally diagnosed. 3. The hepatoportoenterostomy should be considered as the first line treatment in children with CEBA. Most cases will need liver transplantation in the future.

    ABSTRACT: To assess the side-effects of interferon-alpha (IFN-alpha) therapy in children with chronic hepatitis B. This prospective study was performed on one hundred children by interviewing the patients and their parents; clinical examinations and laboratory investigations were performed during and after therapy. The most frequent side-effects of IFN-alpha therapy were fever, flu-like symptoms, and headaches. Lowering of the mean haemoglobin level, leukocyte and platelet count was significant, but transient during INF-alpha treatment. No increase in autoantibody titres or significant alterations in thyroid function was observed. Twelve months after treatment, hepatitis Be antigen (HBeAg) elimination and alanine aminotransferase (ALT) normalization was achieved in 46% of the children; HBeAg and hepatatis B surface antigen (HBsAg) elimination, together with ALT normalization, was achieved in 14% of the cases. The side-effects of the IFN-alpha therapy in children such as fever, flu-like symptoms and bone marrow suppression are common, but transient and mild.

    ABSTRACT: Parvovirus B19 infection can be associated with arthritis in children and adults. The causative role of PB19 infection in arthritis and ulcerative synovitis would prove the etiology of juvenile idiopathic (jia) and reumatoid arthritis (ra). The aim of this study was the evaluation of the role of PB 19 infection in children's arthritis. The group of 41 children with the diagnosis of jia, arthralgia, reactive arthritis and nodular erythema according to EULAR criteria was examined. In early stage of arthritis lasting less than 3 months, there were 22 and in prolonged period lasting more than 3 months there were 19 children. No evidence of PB19 genome was detected by PCR reaction in blood of the examined patients. The possible reasons of the obtained negative results in this study were discussed. PB19 research should be performed in more cases of children's arthritis, both using PCR and by serological methods.

    ABSTRACT: The aim of the study was to present diagnostic problems, different clinical presentations and results of treatment of cytomegalovirus infections in neonates and infants. The study was carried out in a group of 31 children from 10 days to 12 months of age (17 boys, 14 girls). The diagnosis was based on serological investigations (presence of specific IgM antibodies and/or increasing titer of IgG antibodies), presence of intermediate or early CMV antigen in peripheral blood leukocytes or positive blood or urine PCR results. The treatment of 25 cases involved intravenous administration of gancyclovir at 5-7 mg/kg daily doses for 14-21 days. In 1 case, hyperimmunized anti-CMV serum - Cytotect was used. The most common clinical symptoms were jaundice, hepato- and splenomegaly. Clinical investigations demonstrated increased aminotransferese activity and the signs of cholestasis. Other frequent findings included anemia, leukocytosis with atypical lymphocyte forms present, as well as thrombocytopenia. In majority treated patients, rapid regression of the clinical symptoms and normalization of transaminases activity was observed. Good outcome of the therapy was confirmed by immunological investigations. The effects of the terapy were similar irrespective of the dose and duration of gancyclovir treatment. The tolerance of the drug was good - no indications for discontinuation of the treatment were observed in any of the patients. The clinical presentations of cytomegalovirus disease in infants are varied, the diagnosis of the disease should be considered in children with persistent jaundice, especially if it is accompanied by hepatomegaly and increased aminotransferase activity or signs of cholestasis. Despite relatively good tolerance of the drug by children, the patients should be monitored for possible side effects, especially myelo- and nephrotoxic.

    ABSTRACT: One hundred children with chronic hepatitis B, aged 1-17.3 years participated in the study. The results of treatment with interferon alpha (IFN-alpha) were evaluated. An attempt was made to define the factors predicting positive response to treatment. Three million units of IFN-alpha 2a or 2b were given by subcutaneous injections to analysed patients 3 times a week for 20 weeks. Positive treatment outcome reflected in HbeAg elimination was observed in 46% of children. High AlAT activity preceding therapy had a statistically significant effect on positive treatment outcome. The inhibition of HBV replication caused by the treatment was permanent and it coexisted with the normalisation of AlAT activity in blood serum. Full response to therapy with IFN-alpha measured with the elimination of HbeAg and HbsAg was observed in 14% of children. It was favoured by high AlAT activity before treatment and short HBV duration.

    ABSTRACT: The aim of this study was to assess the correlation between the prevalence of Helicobacter pylori strains possessing cytotoxin-associated gene A (cagA) in children and the intensity of clinical complaints and morphological changes of the gastric mucosa. A group of 80 children with gastrointestinal complaints was included in this study. Pathologists examined mucosal biopsy specimens from these patients. The urease test and multiplex polymerase chain reaction (MPCR) were used to identify H. pylori strains. In the group of children infected with cagA-positive H. pylori strains, fourth-degree gastritis was more frequent than in the group with cagA-negative H. pylori colonization. In histopathological assessment, infection with cagA-positive H. pylori was associated also with higher grades of inflammatory intensity and activity. Marked inflammation of the antral mucosa was significantly more frequent in children infected with cagA-positive H. pylori than in those infected with cagA-negative H. pylori, as assessed endoscopically and histopathologically. No specific symptoms for cagA-positive and cagA-negative H. pylori infection were observed.

    ABSTRACT: THE AIM of this study was to estimate the efficacy of nucleoside analogue (lamivudine) in the therapy of chronic viral hepatitis type B in children, after previous, ineffective treatment with interferon-alpha. we analyzed 53 children with chronic viral hepatitis type B, who had not responded to Interferon-alpha treatment conducted 1-7,5 years before this study (mean 4,0 +/- 7,5; median 4 years). Inclusive criteria to re-therapy with lamivudine were as follows: increased serum alanine aminotransferase activity, detected at least three times during 6 months before treatment, HBsAg and HBeAg present in the blood, viral HBV DNA detected for at least 6 months before the beginning of lamivudine therapy (above 200 genome copies per mL) and inflammation activity observed in liver biopsy specimen (biopsy performed within previous 24 months). Evaluation of side-effects of lamivudine therapy was based on anamnesis (subjective data) and laboratory tests performed regularly in the time of clinical visits during and after the end of the treatment. all the children concluded the treatment. Before lamivudine therapy, serum alanine aminotransferase activity ranged between 20-590 IU/L. In 28,4% of children it was less than 100 IU/L. In almost all the children moderate staging and grading were observed in liver biopsy specimens. HBV DNA in serum ranged between 200-200000 copies/mL: in 31 children (58,4%) HBV DNA exceeded 200000 copies/mL, in 5 (28,3%) was between 10000 and 200000 copies/mL, and in 7 (13,2% ) was below 10000 copies/mL. Applied treatment resulted in alanine aminotransferase activity normalization in 79,2% of children, mostly after 2-11 months (mean 3,9 +/- 2,7; median 3,8 months). HBeAg/HBeAb seroconversion was achieved in 28,3% of children, usually at the end of lamivudine therapy (approximately after 12 months). Sustained viral response was observed in 24,5% of treated children. There were no undesirable effects of therapy noted. Serum alanine aminotransferase activity increased slightly and temporarily in 4 children between 3rd and 12th month of therapy. In 2 of these children YMDD mutation was detected. lamivudine is effective, safe and well tolerated in treatment of chronic viral hepatitis type B, following unsuccessful interferon-alpha therapy. Serum alanine aminotransferase activity normalized in most of the patients. HBeAg/HBeAb seroconversion as well as positive viral response is mostly connected with low level of HBV DNA before therapy.

    ABSTRACT: of the study was to analyse the etiology of home acute diarrhea in children. 2636 children with community-acquired acute diarrhea were included in the study. Stool samples were analysed for the presence of Salmonella spp, Shigella spp, rotaviruses and adenoviruses. etiology of acute diarrhea was established in 1149 out of 2636 children (43.6%). Among the children with known etiology - rotaviral diarrhea was most frequently diagnosed (24.67%), whereas salmonellosis - in 7.06% of cases, EPEC C - 6.37%, EPEC B - 2.92%, EPEC A - 1.89%, adenoviral diarrhea in 0.68%. Mean age of children with bacterial acute diarrhea (Salmonella, EPEC A, B, C) was higher as compared to the mean age of children with rotaviral acute diarrhea (p < 0.002). Rotaviral acute diarrhea was more frequently diagnosed in girls (p < 0.025), whereas bacterial - in boys (p < 0.044). The highest prevalence of acute rotaviral diarrhea was found in winter/spring, with peak in April. commonly used diagnostic procedure does not allow to establish the etiology of acute home diarrhea in children in most cases. Rotavirus is found in the majority of diagnosed cases. It seems reasonable to expand the spectrum of diagnostic tests in cases of acute diarrhea in children.

    ABSTRACT: The aim of the paper was to describe therapeutic difficulties in a patient with ulcerative colitis. In the long-term clinical course of the disease a concomitant infection with hepatotropic viruses (HBV, HCV) was diagnosed. Due to the different treatment of autoimmunological diseases and chronic viral hepatitis the necessity of further search of therapeutic schedules for this group of patients is still needed.
