RESUMO
BACKGROUND: This case report presents a history of familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC). The patient was admitted to the hospital with hypertensive encephalopathy. FHHNC is a rare autosomal recessive disease caused by mutations in CLDN16 or CLDN19, resulting in insufficient magnesium and calcium kidney reabsorption. FHHNC manifestation starts in childhood, and over the years, its development leads to nephrocalcinosis and, consequently, chronic kidney disease (CKD), which is not slowed by routine administration of magnesium and thiazide diuretics. Ultimately, all FHHNC patients need kidney replacement therapy (KRT). CASE PRESENTATION: The patient was a 28-year-old male diagnosed with FHHNC and admitted to the emergency room due to hypertensive encephalopathy. The current situation was the patient's second hospitalization related to a hypertensive emergency caused by under-dialysis. Despite the signs of insufficient functioning of peritoneal dialysis (PD) (the primary chosen form of KRT), the patient refused the proposed conversion to hemodialysis (HD). Symptoms observed upon admission included disorientation, anxiety, and severe hypertension, reaching 213/123 mmHg. Due to his clinical condition, the patient was transferred to the intensive care unit (ICU), where the introduction of continuous veno-venous hemodiafiltration and hypotensive therapy stabilized blood pressure. Within the next few days, his state improved, followed by discharge from ICU. Eventually, the patient agreed to transition from PD to in-center HD. At the time, he was qualified for kidney transplantation, waiting for a compatible donation. CKD and dialysis are factors that significantly affect a patient's quality of life, especially in young patients with congenital diseases like FHHNC. CONCLUSIONS: For the aforementioned reasons, appropriate education and psychological support should be ensured to avoid the harmful effects of therapy non-compliance.

Although the natural niche for H. pylori (Hp) is the human stomach, for widespread infection to occur this microorganism may need to survive in the external environment. Molecular techniques such as polymerase (PCR) have revealed the presence of Hp DNA in water, indicating that this environment could act as a reservoir for this bacterium. The aim of this study was to analyse the occurrence of Hp in tap water from Cracow and to examine the relationship between 26 parameters and the presence of Hp DNA due to the lack of such information related to this issue in Poland. Additional aim of this study was to determine whether the correlation between Hp DNA detection and seasonal changes of water quality in 379 water samples collected from various water treatment plants (WTPs), could be found. Water samples were subjected to PCR for glmM and cagA genes. Ionic and organic composition of microelements were determined in accordance to Polish and ISO standards. The data obtained from tests show that 212 (55.96%) objects were Hp DNA (glmM) positive and among them 145 (68.40%) waters samples revealed expression of cagA. Linear Discriminant Analysis and Principal Component Analysis were used and provided that the selected variables (p < 0.05): colour, pH, conductivity at 25°C, chlorides, nitrites, nitrates, phosphates, chlorates, chlorites, sulphates, free chlorine, sodium, magnesium, potassium, calcium, organic carbon, trichloromethane, bromodichloromethane, dibromochloroethane, total iron, ammonium ion, and Æ©TMHs distinguished the water samples that contain Hp DNA and do not contain Hp DNA. We conclude that the ionic and organic composition of microelements in water might influence the presence of Hp. Thus, determination of the selected microelements may indirectly indicate or sometimes predict the presence of Hp in drinking water.

The aim of the work was to determine a degree of explanation of the variation of central fat distribution described by the waist-to-height ratio (WHtR) and waist circumference (WC) by both environmental and biological factors, including hormonal ones. The authors also intended to define the factors which are connected with a risk of abdominal obesity in girls. The study material includes a cross-sectional sample of 297 girls aged 916 years, examined in sport and regular schools in Cracow, Poland. Direct anthropometric measurements were done, breast development was assessed (Tanner stage) and leptin and ghrelin concentration in blood serum was estimated (by RIA method). The girls' lifestyles and socio-economic status were investigated through survey questionnaires. The stepwise descending regression method was applied to evaluate a degree of WC, WHtR and BMI variation explanation. A logistic regression analysis was conducted to indicate factors connected with a risk of abdominal obesity (WHtR ³ 0.50) by calculating odds ratio (OR) and 95% confidence interval (CI). Variation of WC and WHtR was explained in, respectively, 53% and 44% by biological factors i.e. age, body height, the Tanner stage and blood serum leptin and ghrelin concentration as well as by environmental factors i.e. obesity prevalence in fathers and the girls' high physical activity. Variation of BMI was explained in 56% by a similar set of variables, excluding the level of physical activity. The biological factors were the highest determinants of an adipose tissue distribution type in the girls. Besides biological factors a significant role was also played by the environmental ones: obesity prevalence in fathers and high level of physical activity. The waist to height ratio seemed to be a more sensitive identifier of environmental behaviours than the general adiposity index.

Zinc has been reported to exert a gastroprotective action against various experimental gastric lesions suggesting that this trace element is involved in the integrity of the gastric mucosa. Compounds containing zinc, such as polaprezinc, were developed in Japan and used as an antiulcer drugs in the treatment of human peptic ulcer disease. However, the precise mechanism of Zn(2+) containing compounds and their effects on mucosal integrity, gastroprotection and ulcer healing remain unclear. We have determined the efficacy of zinc hydroaspartate, a compound containing Zn(2+), in the mechanism of gastric secretion and ulcer healing in rats with chronic gastric ulcers induced by acetic acid (initial ulcer area = 28 mm(2)). Rats with gastric ulcers were randomized into two groups: A) with gastric fistulas (GF) and B) without gastric fistulas and received a daily treatment with zinc hydroaspartate (32-130 mg/kg-d i.g.) for 3, 7 and 14 days. At the termination of each treatment, the area of gastric ulcers were examined by planimetry, the gastric blood flow (GBF) at ulcer margin was assessed by laser Doppler flowmetry and H(2)-gas clearance methods. The venous blood was withdrawn for a measurement of plasma gastrin levels by radioimmunoassay (RIA). The concentration of Zn(2+) in the gastric juice and mucosa at the ulcer margin were determined by differential pulse anodic stripping voltammetry (DPASV) and flame atomic absorption spectrometry (FAAS) methods and the gastric biopsy samples were taken for histopathological assessment of the quality of ulcer healing. The ulcers healed gradually, with the ulcer area in the vehicle control rats being diminished by 15%, 48% and 78% upon ulcer induction at 3, 7 and 14 days, respectively. Zinc hydroaspartate dose-dependently inhibited the area of gastric ulcer, the dose reducing this area by 50% (ID(50)) being about 60 mg/kg-d. The mucosal concentration of Zn(2+) significantly was unchanged from the baseline immediately after ulcer induction (day 0) and at day 3 but then it rose significantly at day 7 after ulcer induction. Treatment with zinc hydroaspartate (65 mg/kg-d i.g.), which significantly raised the gastric luminal and mucosal levels of Zn(2+), significantly accelerated ulcer healing at day 7 upon ulcer induction. The GBF, which reached a significantly higher value at the ulcer margin than the ulcer bed, was significantly increased in rats treated with zinc hydroaspartate compared with vehicle-controls. The gastric acid output was significantly inhibited in GF rats with gastric ulcer at day 3 then restored at day 14 followed by a significant rise in the plasma gastrin levels. Treatment with zinc hydroaspartate significantly inhibited gastric secretion and also significantly raised the plasma gastrin level when compared to vehicle-control rats. We concluded that 1) trace micronutrients such as Zn(2+) could be successfully measured in the gastric juice and gastric mucosa during ulcer healing; 2) compounds chelating of Zn(2+) can exert a beneficial influence on the ulcer healing via Zn(2+) mediated increase in gastric microcirculation, antisecretory activity and gastrin release, which may enhance the cell proliferation and differentiation during ulcer healing, ultimately exerting a trophic action on the ulcerated gastric mucosa.

Modern gastroenterology started in early 19(th) century with the identification by W. Prout of the inorganic (hydrochloric) acid in the stomach and continued through 20(th) century with the discoveries by I.P. Pavlov of neuro-reflex stimulation of gastric secretion for which he was awarded first Nobel Prize in 1904. When concept of nervism or complete neural control of all digestive functions reached apogeum in Eastern Europe, on the other side of Europe (in United Kingdom), E. Edkins discovered in 1906 that a hormone, gastrin, may serve as chemical messenger in stimulation of gastric acid secretion, while L. Popielski revealed in 1916 that histamine is the most potent gastric secretagogue. K. Schwartz, without considering neural or hormonal nature of gastric secretory stimulation, enunciated in 1910 famous dictum; "no acid no ulcer"; and suggested gastrectomy as the best medication for excessive gastric acid secretion and peptic ulcer. In early 70s, J.W. Black, basing on earlier L. Popielski's histamine concept, identified histamine-H(2) receptors (H(2)-R) and obtained their antagonists, which were found very useful in the control of gastric acid secretion and ulcer therapy for which he was awarded in 1972 second Nobel Prize in gastrology. With discovery by G. Sachs in 1973 of proton pumps and their inhibitors (PPI), even more effective in gastric acid inhibition and ulcer therapy than H(2)-R antagonists, gastric surgery, namely gastrectomy, practiced since first gastric resection in 1881 by L. Rydygier, has been considered obsolete for ulcer treatment. Despite of the progress in gastric pharmacology, the ulcer disease remained essentially "undefeated" and showed periodic exacerbation and relapses. The discovery of spiral bacteria in the stomach in 1983 by B.J. Marshall and R.J. Warren, Australian, clinical researches, awarded in 2005 the Nobel Prize for the third time in gastrology, has been widely considered as a major breakthrough in pathophysiology of gastritis and peptic ulcer, which for the first time can be definitively cured by merely eradication of germ infecting stomach. This overview presents the mechanism of induction of gastritis and peptic ulcer by the H. pylori infection and describes accompanying changes in gastric acid and endocrine secretion as well as the effects of germ eradication on gastric secretory functions and gastroduodenal mucosal integrity.

OBJECTIVE: Family unit is generally accepted as one of the contributors to Helicobacter pylori infection that is most frequently acquired in childhood, so it seems logical to diagnose and treat this infection in childhood. This study was designed to assess H. pylori prevalence in children from shepherd families having contacts with sheep. MATERIAL AND METHODS: This study involved 146 children (58 M/88 F, age 6-17 years; mean: 10.2 years) from families living in Polish Tatra Mountains with contact (group A, n=58) or without contact with sheep (group B, n=88). H. pylori status was determined by (13)C-urea breath test and was compared to 141 age- and gender-matched urban controls (group C). In both groups of mountain children, the anti-H. pylori and anti-CagA IgG were measured by ELISA and serum gastrin, ghrelin and leptin concentrations by RIA. RESULTS: The H. pylori prevalence in group A was significantly higher (58.6%) than that in group B (21.6%) and urban controls (26%). Serum gastrin concentrations were significantly higher in H. pylori-positive than in H. pylori-negative mountain children (52.2+/-5.8 pmol/L versus 22.7+/-2.1 pmol/L), while serum ghrelin and leptin concentrations were significantly lower in H. pylori-infected (741+/-112 pg/mL and 3.6+/-0.8 ng/mL) than in non-infected children (1323+/-104 pg/mL and 8.6+/-2.4 ng/mL). CONCLUSIONS: Children with sheep contact show about twice higher H. pylori prevalence and higher serum gastrin but lower ghrelin and leptin levels than those without H. pylori infection. Considering almost 100% positive 13C-urea breath test in sheep, it is reasonable to propose that H. pylori infection in shepherd children may originate from sheep and the infection might, therefore, be considered as zoonosis.

BACKGROUND: Helicobacter pylori, NSAID and cigarette smoking are major risk factors for gastroduodenal ulcers. However, the results of studies on the interaction between these factors on ulcerogenesis are controversial. This study was designed to examine the association between gastroduodenal ulcers and H. pylori infection, NSAID use, smoking and age. METHODS: 5967 dyspeptic patients underwent 13C-urea breath test (UBT) and upper endoscopy, while age and dyspeptic symptoms were reported. RESULTS: Out of 5967 patients, 31.8% were ulcerated; 9.2% had gastric, 17.2% duodenal and 5.4% both gastric and duodenal ulcers. H. pylori was found in 72.5% of gastric ulcer patients, in 83.6% of duodenal ulcer patients, in 76.9% of gastroduodenal ulcer patients and in 64.8% of dyspeptic patients. The gastric, duodenal and gastroduodenal ulcers were related to H. pylori significantly and the respective ORs were: 1.44, 2.77 and 1.81. NSAID alone was used by 6.2%-12.7% of ulcer patients, tending to raise only the risk of gastric ulcer but reducing that of duodenal and gastroduodenal ulcers. The H. pylori prevalence was significantly higher in smokers (76%) than in non-smokers (67%) and the ulcer risk was also significantly higher in smokers than in non-smokers. About 20% of ulcers were 'idiopathic', i.e. without NSAID and H. pylori and the ratio of these ulcers to all ulcers significantly increased during the 5 years of the study. CONCLUSIONS: Based on multivariable logistic regression analysis we conclude that: 1) H. pylori infection, NSAID use, smoking and age play major roles in the pathogenesis of peptic ulcerations; 2) there is a negative interaction between H. pylori and NSAID on duodenal ulcers, suggesting that H. pylori reduces the development of these ulcers in NSAID users, and 3) about 20% of peptic ulcers in the Polish population are unrelated to H. pylori and NSAID use (idiopathic ulcers).

BACKGROUND: Helicobacter pylori infection might, in some instances, be considered as zoonosis. AIM: The aim of this study was to assess the H. pylori prevalence in Polish shepherds and in their families as compared to controls. Patients and methods. A total of 42 shepherds from Polish Tatra Mountains with regular contact with sheep, 28 members of their families with incidental contacts and 61 age- and gender-matched farmer controls without such contacts were involved in this study. H. pylori status was determined by 13C-urea breath test. Serology was used to measure anti-H. pylori and anti-CagA IgG. Plasma gastrin, interleukin-8 and tumor necrosis factor-alpha were also determined. RESULTS: The H. pylori prevalence reached 97.6% in shepherds, 86% in their family members, but significantly less, 65.1%, in controls without contact with sheep. Anti-H. pylori IgG, anti-CagA in contact groups were significantly higher than in controls. Also, plasma gastrin, interleukin-8 and tumor necrosis factor-alpha had significantly higher values as compared to controls. CONCLUSIONS: Shepherds showed almost 100% H. pylori prevalence and higher incidence of CagA seropositivity, plasma gastrin and pro-inflammatory cytokine levels. Considering 100% positive 13C-urea breath test in sheep, it may be reasonable to suggest that H. pylori infection in shepherds and their family members originates from sheep and H. pylori infection might, therefore, be considered as zoonosis.
