Real-world evidence of ocrelizumab-treated relapsing multiple sclerosis cohort shows changes in progression independent of relapse activity mirroring phase 3 trials. Sci Rep 2023; 13:15003. [PMID: 37696848 PMCID: PMC10495413 DOI: 10.1038/s41598-023-40940-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Accepted: 08/18/2023] [Indexed: 09/13/2023] Open
Abstract
Ocrelizumab is a B cell-depleting drug widely used in relapsing-remitting multiple sclerosis (RRMS) and primary-progressive MS. In RRMS, it is becoming increasingly apparent that accumulation of disability not only manifests as relapse-associated worsening (RAW) but also as progression independent of relapse activity (PIRA) throughout the disease course. This study's objective was to investigate the role of PIRA in RRMS patients treated with ocrelizumab. We performed a single-center, retrospective, cross-sectional study of clinical data acquired at a German tertiary multiple sclerosis referral center from 2018 to 2022. All patients with RRMS treated with ocrelizumab for at least six months and complete datasets were analyzed. Confirmed disability accumulation (CDA) was defined as a ≥ 12-week confirmed increase from the previous expanded disability status scale (EDSS) score of ≥ 1.0 if the previous EDSS was ≤ 5.5 or a ≥ 0.5-point increase if the previous EDSS was > 5.5. PIRA was defined as CDA without relapse since the last EDSS measurement and at least for the preceding 12 weeks. RAW was defined as CDA in an interval of EDSS measurements with ≥ 1 relapses. Cox proportional hazard models were used to analyze the probability of developing PIRA depending on various factors, including disease duration, previous disease-modifying treatments (DMTs), and optical coherence tomography-assessed retinal degeneration parameters. 97 patients were included in the analysis. Mean follow-up time was 29 months (range 6 to 51 months). 23.5% developed CDA under ocrelizumab therapy (n = 23). Of those, the majority developed PIRA (87.0% of CDA, n = 20) rather than RAW (13.0% of CDA, n = 3). An exploratory investigation using Cox proportional hazards ratios revealed two possible factors associated with an increased probability of developing PIRA: a shorter disease duration prior to ocrelizumab (p = 0.02) and a lower number of previous DMTs prior to ocrelizumab (p = 0.04). Our data show that in ocrelizumab-treated RRMS patients, the main driver of disability accumulation is PIRA rather than RAW. Furthermore, these real-world data show remarkable consistency with data from phase 3 randomized controlled trials of ocrelizumab in RRMS, which may increase confidence in translating results from tightly controlled RCTs into the real-world clinical setting.

Excessive laxity of connective tissue in constipated children. Sci Rep 2022; 12:1026. [PMID: 35046501 PMCID: PMC8770553 DOI: 10.1038/s41598-022-05115-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 12/21/2021] [Indexed: 11/18/2022] Open
Abstract
Excessive laxity of the connective tissue refers to a group of inherited abnormalities manifested by disturbances in the functioning of internal organs, including the gastrointestinal tract. Increased susceptibility to stretching of the distal part of the large intestine and abnormal colonic motor function could explain the predisposition to the development of functional constipation in some children. Our aim was to determine whether patients with functional constipation are more likely to be characterized by congenital laxity of connective tissue compared to the population of healthy children. Children diagnosed with functional constipation according to the Rome III criteria were prospectively enrolled in the study (study group, S) and compared to otherwise healthy children (control group, C). Excessive laxity of the connective tissue was evaluated using the Beighton Score (BS) and expressed as median and interquartile range (IQR). The study included 411 patients (median age 7.8 years, min 3 years, max 18 years; 49% male), comprising 211 patients in the S group and 200 children in the C group. The median BS in the S group was significantly higher than in the C group (median: 5 points [IQR: 1–4.5] vs 2 points [IQR: 3–7], respectively; p = 0.000). Furthermore, increased connective tissue laxity was observed more frequently in females (p < 0.05). Increased connective tissue laxity was more frequent in children with functional constipation, especially in girls. Excessive laxity of the connective tissue may be one of the etiological factors of functional constipation in children.

Abstract
INTRODUCTION Cytomegalovirus (CMV) infection in patients with inflammatory bowel disease (IBD) is reactivated by the use of immunosuppressive drugs. CMV infection may produce IBD flares refractory to standard therapy. OBJECTIVE The aim of our study was to assess the efficacy and safety of faecal microbiota transplantation (FMT) for the treatment of CMV colitis in patients with ulcerative colitis (UC) flare. MATERIAL AND METHODS A total of 8 children, with mild to severe UC, positive for CMV PCR in colonic biopsies, received 50-100 ml FMT by nasogastric tube on 5 consecutive days in each of 2 weeks. During the study, the subjects were treated with 5ASA and FMT. Immunosuppressant therapy was withdrawn, when CMV colitis was diagnosed by positive DNA PCR in colonic tissues. The clinical response was defined as a decrease of Paediatric UC Activity Index by ≥20 points. RESULTS At the 6th week of the study, negative colonic CMV DNA PCR was measured after 10 infusions in 7/8 patients. For one boy, 20 infusions were administered to assess CMV elimination from colonic biopsies. A clinical response was observed in 3/8 patients, with clinical remission in 3/8 patients. Faecal calprotectin decreased significantly in 3 patients. CRP normalized in 2 patients after 6 weeks. No serious adverse effects were observed during and after infusions. CONCLUSIONS FMT seems to be an effective and safe treatment option for CMV colitis in children with UC. This is the first study to demonstrate the application of FMT as a new therapeutic option for CMV colitis.

Abstract
Introduction: Antibiotic-associated diarrhea (AAD) is a common adverse reaction to antibiotic treatment affecting up to 21% of children. The aim of the study is to evaluate whether bovine lactoferrin (bLf) might be used for AAD prevention. Materials and Methods: In this prospective, randomized, double-blind, placebo-controlled, single-center study, we enrolled 156 children aged between 1 and 18 years, treated with antibiotic due to acute respiratory or urinary tract infection. We randomly allocated children 1:1 to receive 100 mg of bLf or a placebo twice a day orally for the whole period of antibiotic therapy. The primary outcome was the occurrence of antibiotic-associated diarrhea during and up to 2 weeks after antibiotic therapy. The secondary endpoint was intravenous rehydration or antibiotic withdrawal due to diarrhea. We performed intention-to-treat analysis. Results: We included 150 patients in intention-to-treat analysis. AAD occurred in 16 of 75 (21.3%) patients in bLf group and in 7 of 75 (9.3%) individuals in placebo group [OR = 2.6, (95% CI: 1.01-6.84), p = 0.04]. Relative risk was 2.29 (95% CI: 0.89-5.88). The need for intravenous rehydration occurred in one patient in the placebo group (p = 0.3). We observed no adverse effects in neither of the groups. Discussion: The trial indicated that bLf is not effective in AAD prevention. The risk for AAD was higher in bovine lactoferrin group as compared with placebo. We registered the study protocol on ClinicalTrials.gov (NCT02626104).

Knockout of purinergic receptor Y13 (P2Y13) results in an improved outcome of metabolic syndrome in mice. Eur Heart J 2020.

Abstract
Abstract
Metabolic syndrome (MetS) clusters the main risk factors for cardiovascular diseases (CVDs) and endocrine dysfunction. The pathomechanism of MetS is described as local death of hypertrophic adipocytes releasing danger-associated molecular patterns (DAMPs) such as nucleotides (e.g. ADP). This promotes a long term inflammation of adipose tissue via activation of purinergic receptors with a gradual shift towards a pro-inflammatory environment. The ADP receptor P2Y13 is both described in metabolic and immunological processes. These combined characteristics make the P2Y13 an interesting candidate to investigate its role in MetS. Nevertheless, the role of P2Y13R in the pathogenesis of MetS is currently unknown and shall be analyzed in this study.
BMDM isolation and differentiation to Mϕ using M-CSF and subsequent stimulation with medium, LPS and IFNγ or IL4; Expression was quantified using Taqman. Male C57Bl6/J wild-type (WT) and P2Y13-deficient (KO) mice were fed a HFD for 20 weeks; body weight and food consumption were recorded weekly. GTT, ITT and metabolic cages were performed after 15 weeks with euthanization after 20 weeks. In order to distinguish the effect of hematopoetic or somatic cells, mice were lethally irradiated with 9.4Gy and reconstituted with donor bone-marrow (BM) via tail vein injection.
We observed a unique expression of P2Y13R on pro-inflammatory M1 Mϕ. After HFD feeding KO mice showed higher O2 consumption compared to WT mice (AUC of O2 consumption on 2nd day= KO:61620±2261mL/kg vs WT: 53830±916mL/kg, p<0.05). Although KO mice consumed more food compared to WT littermates (KO:5.7±0.5g/d vs WT:3.1±0.1g/d, p<0.0001), they showed significantly decelerated weight gain (e.g.week 15→KO:147,292±5,26% vs WT:180.8±15.9%, p<0.05). Obese KO animals outperformed obese WT littermates in a peritoneal glucose tolerance test (GTT) (2h post-injection (post-i.) →KO:273.7±46.3mg/dL vs WT: 555.0±40.8mg/dL, p<0.05). KO mice on HFD were protected from developing a fatty liver. HFD KO mice receiving WT BM show accelerated weight gain compared to KO mice receiving KO BM (e.g.week 10 WT in KO: 111.2±2.2% vs KO in KO: 102.2±1.2%, p<0.05). In the GTT irradiated KO mice either receiving KO or WT BM are protected from HFD induced impaired glucose homeostasis (45min post-i.; KO→KO:222.1±21.2mg/dL vs WT→KO:232.8±15.9mg/dL vs WT on chow diet:240.4±18.6mg/dL). Contrary, WT mice receiving KO or WT BM developed a glucose resistance comparable to non-irradiated WT mice (45min post-i.; WT→WT:423.8±61.7mg/dL vs KO→WT:434.3±51.1 vs WT on HFD:574.4±7.9).
P2Y13 KO improves the outcome of MetS in mice with improved glucose homeostasis, decelerated weight gain, no fatty liver development and better metabolic turnover. BM transplantation experiments suggest a somatic component as possible explanation of these observations. Given these beneficial metabolic effects, we hypothesize that antagonization of P2Y13R could be a promising therapeutic tool in the field of MetS.

Abstract
The study dedicated mainly to general practitioners of ENTs discusses the principles of antibiotic therapy of the most common diseases that this specialty deals with, namely acute tonsillitis and throat inflammation, acute otitis media (AOM), and acute sinusitis. The most common errors in the antibiotic therapy of these diseases are also presented. The basic antibiotic in streptococcal pharyngitis is and remains oral penicillin administered for 10 days. The basic antibiotic, if it is needed, in AOM and acute sinusitis is amoxicillin in high doses. The most common mistake in antibiotic therapy is to start it with macrolides, especially azithromycin, a "comfortable" antibiotic but with the greatest strength of stimulating drug resistance to all macrolides. Another condition that has been highlighted due to frequency and in this case completely unnecessary antibiotic therapy is subglottic laryngitis in which the basis of treatment are systemic steroids, inhalation adrenaline and possibly inhaled steroids. Practical advice on this type of symptomatic management has been presented.

Cerebrospinal fluid findings in reversible cerebral vasoconstriction syndrome: a way to differentiate from cerebral vasculitis? Clin Exp Immunol 2018; 193:341-345. [PMID: 29722896 DOI: 10.1111/cei.13148] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2018] [Revised: 03/31/2018] [Accepted: 04/23/2018] [Indexed: 11/29/2022] Open
Abstract
Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by an acute onset of severe headache and multi-focal segmental vasoconstriction of cerebral arteries resolving within 12 weeks. Diagnostic criteria include normal or near-normal findings in cerebrospinal fluid (CSF) analysis, especially leucocyte levels < 10/mm³. Distinguishing RCVS from primary angiitis of the central nervous system (PACNS) is essential to avoid unnecessary and sometimes unfavourable immunosuppressive treatment. We reviewed retrospectively the clinical and diagnostic data of 10 RCVS patients who presented in our neurological department from 1 January 2013 to February 2017. The main purpose was to verify whether CSF leucocyte counts < 10/mm³ serve to discriminate RCVS from PACNS. Five of six patients who underwent lumbar puncture presented with CSF leucocyte levels ≥ 10/mm³. Two patients had a history of misinterpretation of CSF pleocytosis as cerebral vasculitis and of immunosuppressive treatment. A complete restitution of cerebral vasoconstriction was evident in all. No patient had further cerebral strokes or bleedings without immunosuppressive treatment over more than 12 weeks. Despite the established diagnostic criteria, RCVS can manifest with CSF leucocyte levels > 10/mm³. Careful anamnesis and the response of 'vasculitis-like angiography' to nimodipine given as a test during angiography and as oral medication are key to differentiate RCVS from cerebral vasculitis.

Abstract
INTRODUCTION Vaccination with formulations containing pneumococcal protein antigens such as pneumolysin toxoid (dPly) and histidine-triad protein D (PhtD) may extend serotype-related protection of pneumococcal conjugate vaccines (PCVs) against Streptococcus pneumoniae. METHODS This phase II, multi-center, observer-blind trial conducted in Europe (NCT01204658) assessed 2 investigational vaccines containing 10 serotype-specific polysaccharide conjugates of PHiD-CV and either 10 or 30µg of dPly and PhtD each. Infants randomized 1:1:1:1 received 4 doses of PHiD-CV/dPly/PhtD-10, PHiD-CV/dPly/PhtD-30, PHiD-CV, or 13-valent PCV (PCV13), co-administered with DTPa-HBV-IPV/Hib, at ages ∼2, 3, 4 and 12-15months. Occurrences of fever >40.0°C following primary vaccination with PHiD-CV/dPly/PhtD vaccines compared to PHiD-CV (non-inferiority objective), dose superiority, safety and immunogenicity were assessed. RESULTS 575 children received primary vaccination, and 564 booster vaccination. The non-inferiority objective was met; no fever >40.0°C causally related to vaccination was reported during primary vaccination. Incidence of adverse events appeared similar between the 3 PHiD-CV groups. Serious adverse events were reported in 13, 9, 21 (1 related to vaccination), and 17 children in the PHiD-CV/dPly/PhtD-10, PHiD-CV/dPly/PhtD-30, PHiD-CV, and PCV13 groups, respectively. PHiD-CV/dPly/PhtD-30 was superior to PHiD-CV/dPly/PhtD-10 in terms of post-dose 3 anti-Ply and Anti-PhtD antibody levels. Anti-Ply and anti-PhtD antibody levels were higher in both PHiD-CV/dPly/PhtD groups than in controls and increased from post-primary to post-booster timepoint. Post-primary and booster vaccination, for each PHiD-CV serotype, ≥98.5% of participants in PHiD-CV/dPly/PhtD groups had antibody concentrations ≥ 0.2μg/mL, except for 6B (≥72.3%) and 23F (≥82.7%) post-primary vaccination. Similar results were observed in the PHiD-CV group. Immune responses to protein D and DTPa-HBV-IPV/Hib were within similar ranges for the 3 PHiD-CV groups. CONCLUSION Both PHiD-CV/dPly/PhtD formulations co-administered with DTPa-HBV-IPV/Hib in infants were well-tolerated and immunogenic for dPly and PhtD antigens, while immune responses to serotype-specific, protein D and co-administered antigens did not appear altered in comparison to PHiD-CV group.

Abstract
AIM The aim of the study was to evaluate the hospitalization trends in children aged 0-6 suffering from bacterial pneumonia in the years 2007-2011 in Poland. METHODS The data pertained to the hospitalized patients diagnosed with the diseases registered as J13-J15 according to ICD-10. RESULTS In the years 2007-2011, the hospitalization rate increased from 16.3/10,000 to 44.1/10,000 for boys and from 13.8/10,000 to 33.0/10,000 for girls. The most frequently hospitalized children were between 1 and 2 years of age (90.6/10,000 for boys and 58.0/10,000 for girls in 2011). The average length of stay (LOS) of the investigated children fell from 10.1 days in 2007 to 8.2 days in 2011. The longest stays were recorded for the youngest children, under 2 years of age (from almost 11 days in 2007 to around 9 days in 2011). CONCLUSION Bacterial pneumonia is a serious problem of public health and especially babies are at high risk of this disease. Given the effects of vaccinations against Streptococcus pneumoniae conducted all over the world and to a limited extend in Poland as well, further steps towards vaccinating children against pneumococci should be taken in Poland.

Abstract
Trichotillomania is a disorder characterised by inability to control over pulling own hair from various parts of a body resulting in noticeable hair loss. Due to its long-term, progressive course, untreated trichotillomania can lead to disturbances in the functioning of patients and complications which are dangerous to life and health. Due to the ambiguous nature of the symptoms, they often remain unrecognised by clinicians. Most patients are afraid of revealing symptoms and reluctantly seek for professional help. In our opinion, it is necessary to increase the awareness of the disorder of physicians of different specialties to improve the detection, treatment efficacy and to prevent dangerous complications of trichotillomania. This paper summarises the current state of knowledge on the epidemiology, aetiology, clinical presentation, and treatment of trichotillomania. It is also an attempt to create guidelines in all cases of suspected trichotillomania - adapted to Polish conditions. It also highlights the importance of a multidisciplinary treatment as a condition of effectiveness of the therapy and prevention of relapse.

Abstract
Dysbiosis plays a major role in the etiology of inflammatory bowel disease (IBD). Fecal microbiota transplantation (FMT) is a new promising option for IBD treatment. We aimed to assess the effectiveness of a two-week FMT course in children with IBD. Ten patients, 10-17 years of age with moderate to severe IBD received a course of eight doses of freshly prepared FMT via a naso-duodenal tube or gastroscopy. All of the patients had pancolitis. There were eight cases of ulcerative colitis (UC) and two of Crohn's disease (CD). Disease activity was evaluated using the Pediatric UC Activity Index (PUCAI) and Pediatric CD Activity Index (PCDAI) for UC and CD, respectively, CRP, and fecal calprotectin on the day before the first infusion and then on the day before the next course of FMT. Clinical response, defined as a decrease of 15 points in either index, was observed in 9/10 patients (seven UC and two CD). Clinical remission, defined as a PCDAI score ≤ 10 and PUCAI score < 10 measured at the same time point, was observed in 3/8 UC patients and 2/2 CD patients. Side effects observed were self-limiting and benign. We conclude that a short, intensive course of FMT has a beneficial effect on UC and CD colitis. FMT was well-tolerated and safe. Nonetheless, an optimal protocol of FMT administration is crucial for treatment efficacy.

Abstract
BACKGROUND & AIMS Three-dimensional high-resolution anorectal manometry (3DHRAM) provides a topographic image of pressure along the anal canal. We aimed to determine normal 3DHRAM values in children. METHODS We performed a prospective study of 61 children (34 male; mean age, 8.28 years) without any symptoms arising from the lower gastrointestinal tract who were evaluated at the Department of Pediatric Gastroenterology and Nutrition, Medical University of Warsaw, Poland. Manometry procedures were performed by using a rigid probe without medication. Pressure within the anal canal and 3D images of sphincters were measured. If possible, squeeze pressure and thresholds of sensation were evaluated. The population was divided into age groups of <5 years, 5-8 years, 9-12 years, and older than 12 years. RESULTS The mean resting and squeeze sphincter pressures were 83 ± 23 mm Hg and 191 ± 64 mm Hg, respectively. The mean length of the anal canal was 2.62 ± 0.68 cm and correlated with age (r = 0.49, P < .0001). The mean rectal balloon volume to elicit rectoanal inhibitory reflex was 15.7 ± 10.9 cm(3). The first sensation, urge, and discomfort were observed at balloon volumes of 24.4 ± 23.98 cm(3), 45.9 ± 34.55 cm(3), and 91.6 ± 50.17 cm(3), respectively. The mean resting pressure of the puborectalis muscle was 69 ± 14 mm Hg, whereas the mean squeeze pressure was 124 ± 33 mm Hg. There was no statistically significant difference in pressure parameters between age groups. We observed a positive correlation between age and balloon volume needed to elicit discomfort (r = 0.49, P < .001). CONCLUSIONS In a prospective study, we determined normal values from 3DHRAM analysis of children without symptoms arising from the lower gastrointestinal tract. There were no significant differences in pressure results between children of different sexes or ages. ClinicalTrials.gov number: NCT02236507.

Abstract
AIM Trichotillomania is a lack of control of one's hair pulling. It is estimated that about 1% of population develops trichotillomania. In up to 20% of patients with trichotillomania swollowing follows hair pulling. Trichobezoar forms in about 30% of patients with trichofagia. MATERIAL AND METHODS In 2008-2014 3 patients were operated on trichobezoar. One patient has had a history of trichotillomania. On admission abdominal X-ray and ultrasonography revealed abdominal mass. Diagnosis was confirmed in abdominal computed tomography. RESULTS All three trichobezoars were evacuated from the intestinal tract during laparotomy with wide gastric wall opening. In one case - Rapunzel syndrome - hair mass was evacuated also from the duodenum and small bowel. All patients were referred to psychiatrist after finishing of the surgical treatment. CONCLUSIONS In patients operated for trichobezoar as well as other patients with trichotillomania control of hair accumulation in the gastrointestinal tract remains a problem. Authors propose endoscopic follow up scheme in 6, 12, and 24 months after the surgery as well as for other patients with trichotillomania.

Abstract
PURPOSE Anorectal 3-dimensional high definition manometry (3D HRM) could be the best tool for postoperative assessment of restorative surgical procedures for Hirschsprung's disease. The aim of our study was to evaluate patients after surgery for Hirschsprung's disease using 3D HRM. MATERIALS AND METHODS Anorectal function was evaluated using solid state 3D HRM. We measured the length of the anal canal, mean resting squeeze pressures, the presence of rectoanal inhibitory reflex, cough reflex, ano-anal reflex and the bear down manoeuvre. RESULTS We studied 14 children operated on for Hirschsprung's disease. The mean values of pressure asymmetry were higher in patients after the Duhamel procedure than after the TEPT procedure (29.58% vs. 22.26% during resting and 26.1% vs. 14.01% during squeeze, respectively). No difference between the groups was observed in the measurement of all the manometric parameters except the presence of rectoanal inhibitory reflex (87.5% after TEPT vs. 33% after Duhamel). CONCLUSIONS Anorectal 3D HRM evaluation of patients with Hirschsprung's disease demonstrated that the asymmetry of the anal canal occurred in a similar percentage after both procedures.

Abstract
After successful introduction of anti-Haemophilus influenzae (Hi) serotype b vaccination program in Poland, invasive non-b or nontypeable H. influenzae infections have been reported more frequently alike in other countries all over the world. In this paper, we report 2 cases of H. influenzae serotype f (Hif) meningitis with severe clinical presentations which are rarely seen in previously healthy children.The first case is a 6-year-old girl who was admitted to pediatric ward with signs of meningitis. Laboratory tests confirmed bacteremic meningitis caused by Hif. The girl responded very well to administered treatment and recovered without any further complications. No underlying comorbidities were found. The second patient was a 4-year-old boy who, in course of Hif bacteremic meningitis, developed rapid septicemia and, despite aggressive treatment, died within a few hours of hospitalization. The child's past history was unremarkable.By presenting these cases, we would like to remind clinicians that invasive non-b Hi infections can become fatal not only in the group of the youngest children or children with coexisting comorbidities, as most commonly reported in the worldwide literature. At the same time, we want to emphasize the legitimacy of constant monitoring Hi epidemiology in order to take accurate actions if necessary.

Abstract
BACKGROUND AND OBJECTIVES In 2006 the city of Kielce, Poland, introduced a mandatory PCV7 (replaced by PCV13 in 2011) vaccination program against S. pneumoanie for all children under 2 years old. At that time, the neighboring city of Ostrowiec Świętokrzyski had no such large-scale vaccination program in place. This created an opportunity to observe the results of the vaccination by comparing the incidence of pneumonia in these two cities. The aim of this study was to analyze how the incidence of pneumonia among adults was indirectly affected by the PCV7/PCV13 vaccination program in children during the 7 year follow-up period. METHODS We performed a retrospective study. PCV7/PCV13 vaccinations were delivered according to a 2 + 1 schedule. The vaccination rate in the analyzed period amounted to almost 99%. The following age groups were analyzed: 30-49, 50-64 and 65+. The Cochran-Armitage test was used to investigate the significance of the observed trend in pneumonia morbidity. The significance of deviations from a linear trend was also tested. In addition, the importance of the trend (in the case of deviations from linearity) was confirmed with the use of the Mantel test. RESULTS In the 65+ age group there was a decrease of 66.5% in the incidence of diagnosed pneumonia (p < 0.0001). This was followed by smaller, but statistically significant, declines in the other age groups: 30.75% in the 30-49 age group (p = 0.001) and 56.8% in the 50-64 age group (p < 0.0001). This decreasing trend continued for seven consecutive years of observation. In addition, we demonstrated a statistically significant higher rate of pneumonia in all age groups in the City of Ostrowiec Świętokrzyski. CONCLUSIONS The results clearly indicate that the indirect effectiveness of the PCV7/PCV13 vaccine program, performed according to the 2 + 1 schedule and applied in Kielce, Poland, is statistically significant.

Abstract
UNLABELLED In paediatric patients, esophagogastroduodenoscopy (EGD) is commonly performed with the use of sedation. The aim of the study was to compare the effectiveness of propofol and midazolam in providing procedural amnesia and controlling behaviour in children undergoing diagnostic EGD. Children (9-16 years), classified to the first or second class of the American Society of Anaesthesiologists' physical status classification referred for EGD, were randomly assigned to receive propofol with alfentanyl or midazolam with alfentanyl for sedation during the procedure. Within 120 min after the procedure, patients were repeatedly investigated for memory of the procedure and for memory of pain intensity during EGD with the use of the visual analogue scale. Activity and cooperation of the patient during the procedure was assessed with the relative adequacy scale. Of the 51 children, 48 completed the study. Propofol was significantly better than midazolam in inducing amnesia of procedural pain (mean difference 11.53 mm; 95 % confidence interval [CI] 0.96 to 22.10), loss of memory of the procedure (relative risk 0.4; 95 % CI 0.21 to 0.59) and controlling behaviour (relative risk 2.12; 95 % CI 1.33 to 3.36). CONCLUSION In children sedated for EGD, propofol is significantly better than midazolam at providing procedural amnesia and controlling behaviour during the procedure.

BAX inhibitor-1 is a Ca(2+) channel critically important for immune cell function and survival. Cell Death Differ 2015; 23:358-68.

Abstract
The endoplasmic reticulum (ER) serves as the major intracellular Ca(2+) store and has a role in the synthesis and folding of proteins. BAX (BCL2-associated X protein) inhibitor-1 (BI-1) is a Ca(2+) leak channel also implicated in the response against protein misfolding, thereby connecting the Ca(2+) store and protein-folding functions of the ER. We found that BI-1-deficient mice suffer from leukopenia and erythrocytosis, have an increased number of splenic marginal zone B cells and higher abundance and nuclear translocation of NF-κB (nuclear factor-κ light-chain enhancer of activated B cells) proteins, correlating with increased cytosolic and ER Ca(2+) levels. When put into culture, purified knockout T cells and even more so B cells die spontaneously. This is preceded by increased activity of the mitochondrial initiator caspase-9 and correlated with a significant surge in mitochondrial Ca(2+) levels, suggesting an exhausted mitochondrial Ca(2+) buffer capacity as the underlying cause for cell death in vitro. In vivo, T-cell-dependent experimental autoimmune encephalomyelitis and B-cell-dependent antibody production are attenuated, corroborating the ex vivo results. These results suggest that BI-1 has a major role in the functioning of the adaptive immune system by regulating intracellular Ca(2+) homeostasis in lymphocytes.

Abstract
BACKGROUND The aim of this study was to confirm the role of antral nodularity in the diagnosis of Helicobacter pylori (H. pylori) infection in children. MATERIAL AND METHODS This prospective study included 107 children (58 male; 54.2%), between the ages of 3 and 18 years, infected with H. pylori, which was confirmed if the patient had at least 2 of 4 positive test results (urea breath test, urease test in gastric biopsy, histopathology - positive hematoxylin and eosin and Giemsa staining, and/or monoclonal stool ELISA test - Amplified IDEIA™ Hp StAR™). The control group consisted of 234 children with abdominal pain, of similar age, in whom urease test in gastric tissue and histopathology were negative. In both groups, photographs of the gastric antrum taken during endoscopy were evaluated for nodularity by 3 independent endoscopists, blinded to the results of other tests. Sensitivity, specificity, and negative and positive predictive value of nodularity were assessed. Indication for upper endoscopy was chronic abdominal pain not considered to be functional. RESULTS There were no statistical differences between groups regarding sex (chi-square test with Yates's correction: p=0.8763) or age (mean ±SD) 11.77±3.49 and 12.43±3.32, study and control groups, respectively (Mann-Whitney test: p=0.1352). The sensitivity of the presence of nodularity as an indication of H. pylori infection was 91.6% and specificity was 91%. PPV of gastric nodularity was 81% and NPV was 96%. CONCLUSIONS Antral nodularity is reliable test. Physicians could start treatment of H. pylori infection whenever gastric nodularity is observed and the urease test result is positive, without waiting for histopathology results.

Abstract
Inflammatory bowel disease (IBD) patients may be at a higher risk for developing infections due to underlying disease, malnutrition, surgery, or immunosuppressive therapy. Therefore, protecting this group against infections is of particular importance. Immunisation against vaccine-preventable diseases is strongly recommended. This article for the first time summarises data on immunogenicity and safety of vaccines in IBD children and provides an update on some important issues regarding immunisation in these group of children.

Abstract
BACKGROUND Incidence of shingles in different regions of the world ranged from 300 to 500/100,000 persons, and in the population older than 80 years of age reaches more than 1000/100,000. In the age group 50+ the incidence is enough high to be a serious medical and economic burden. Lack of details about the incidence and frequency of complications in Polish population let us too made an attempt to assess the scale of the problem, among others to the purpose of the evaluation of the legitimacy of implementing vaccination in the 50+ population. METHODS First, based on coming data from the Świętokrzyskie Province Division of the National Health Fund we judged the incidence of shingles in this province in 2013 in individual ancient groups and depending on detailed diagnoses and with the division into the basic health, clinic and hospital care. Second, based on gathered data through NIZP-PZH, we judged hospital morbidity connected with shingles in Poland in 2008-2012 years, in individual ancient groups. RESULTS Extrapolating the data from the Świętokrzyskie province we assess the incidence of shingles on average 338.8/100,000. She is tallest in the age group 50+ (614.3/100,000) and in this group also the most complications are being observed. Hospital morbidity in entire Poland showed in 2008-2012 years the frequency on average 4.93-5.42/100,000, in the group of 0-19 years; 0.10-1.50/100,000, in the group of 20-49 years; 4.9-5.42/100,000 and in the 50+ group--9.99-13.37/100,000. CONCLUSIONS (1) Shingles, especially in the 50+ age group, constitutes a serious health problem in Poland, being a cause of numerous advices in basic health care and at clinics in Poland, as well of numerous hospitalizations and dangerous complications. (2) It seems, that active immunization against shingles, especially of 50+ persons, would be a favourable solution from the individual, as well as public perspective.

Abstract
BACKGROUND Retinal optical coherence tomography (OCT) permits quantification of retinal layer atrophy relevant to assessment of neurodegeneration in multiple sclerosis (MS). Measurement artefacts may limit the use of OCT to MS research. OBJECTIVE An expert task force convened with the aim to provide guidance on the use of validated quality control (QC) criteria for the use of OCT in MS research and clinical trials. METHODS A prospective multi-centre (n = 13) study. Peripapillary ring scan QC rating of an OCT training set (n = 50) was followed by a test set (n = 50). Inter-rater agreement was calculated using kappa statistics. Results were discussed at a round table after the assessment had taken place. RESULTS The inter-rater QC agreement was substantial (kappa = 0.7). Disagreement was found highest for judging signal strength (kappa = 0.40). Future steps to resolve these issues were discussed. CONCLUSION Substantial agreement for QC assessment was achieved with aid of the OSCAR-IB criteria. The task force has developed a website for free online training and QC certification. The criteria may prove useful for future research and trials in MS using OCT as a secondary outcome measure in a multi-centre setting.

Abstract
BACKGROUND Crohn disease (CD) is a chronic inflammatory process of gastrointestinal tract, which frequently affects children. Recent advances in Magnetic Resonance Imaging (MRI) technique have made small bowel imaging possible, what is extremely useful in pediatrics. The purpose of this article is to describe the characteristic MR enterography findings and to present the advantages of this modality in pediatric patients. MATERIAL/METHODS A group of 40 patients referred from the Department of Pediatric Gastroenterology and Nutrition, Medical University of Warsaw was included in the analysis. The patients' age ranged from 7 to 18 years (mean age 14 years). Among the study participants, 28 patients were diagnosed with CD, whereas 12 patients had a history of ulcerative colitis or were strongly suspected of CD based on clinical data. The examinations were performed on GE Signa HD 1,5 T system. Small bowel distention was achieved by oral administration of 600-1000 ml of hyperosmotic solution of polyetylenglycol (PEG). Prior to the examination, 20-40 mg of a spasmolytic drug, hioscine-N-butylobromide (Buscolysin(®)), was administrated to reduce peristaltic movements. RESULTS The abnormal small bowel segments were found in 21 patients and the features of colonic disease were detected in 5 patients. In 2 patients the lesions involved both small and large bowel. In 16 subjects mural changes were not found. Among studied patients, following signs of small bowel inflammation were fund: bowel wall thickening (n=21), submucosal edema (n=8), segment wall hyperenhancement (n=18), deep ulceration (n=6), fistula (n=3), stenosis (n=7), mesenteric signs such as hyperemia (n=9), fibrofatty proliferation (n=8) and lymphadenopathy (n=28). CONCLUSIONS MR enterography is an excellent examination, which provides an accurate information about severity and activity of and complications related to CD. It is especially valuable in children, because of lack of the negative consequences of repeated exposure to ionizing radiation.

Abstract
BACKGROUND AND AIMS Clostridium difficile is the major cause of antibiotic-associated diarrhea and is the most well known bacterial pathogen associated with inflammatory bowel disease (IBD). Enterotoxigenic Clostridium perfringens has also been detected in up to 15% of antibiotic-associated diarrhea cases, and it has not been found in healthy people. The aim of this study was to investigate the prevalence of C. perfringens infection in pediatric patients with IBD. METHODS This was a prospective, controlled study evaluating pediatric IBD patients in the Department of Pediatric Gastroenterology and Nutrition in Warsaw, Poland. All of the patients were diagnosed according to the Porto criteria. There were two control groups: (1) non-IBD patients that were suspected for bacterial diarrhea and (2) healthy children. Stool samples were collected on the day of admission. C. perfringens infection diagnosis was based on a positive stool enzyme immunoassay (C. perfringens enterotoxin test kit TechLab). RESULTS 91 fecal specimens from patients with IBD were collected. The average patient age was 11.7 years in IBD group, 7.4 years in non-IBD patients with diarrhea, and 7.4 years in healthy children. The prevalence of C. perfringens infection was 9% (8/91; CI 95% 4.6-16.4). There were more Crohn's patients (6/8) in the C. perfringens positive group. There was no C. perfringens infection in the two control groups. CONCLUSION Our pilot data add evidence to the hypothesis that Clostridia other than C. difficile may play a significant role in the clinical course of IBD. However, further studies are needed to confirm this.

Abstract
Invasive pneumococcal disease (IPD) is a main cause of mortality associated with pneumococcal infections. Although, IPD is regarding mainly small children and persons in the age > 65 years, the investigations showed that because of IPD exactly sick persons are burdened with the greatest mortality in the older age, rather than of children. The most frequent form of IPD is community acquired pneumonia (CAP) with the bacteremia. The presence of even a single additional risk factor is increasing the probability of the unfavorable descent of pneumococcal infection. The risk factors for IPD and/or pneumonia with bacteremia apart from the age are among others asthma (> 2 x), chronic obstructive pulmonary disease (COPD), sarcoidosis (4 x), idiopathic pulmonary fibrosis (5 x), bronchiectases (2 x), allergic alveolitis (1.9 x) and pneumoconiosis (2 x), type 1 diabetes (4.4 x), type 2 diabetes (1.2 x), autoimmune diseases (e.g. rheumatoid arthritis (4.2 to 14.9 x), kidney failure with the necessity to dialysis (12 x), immunosuppression, cardiovascular disease, alcoholism and cancers. Examinations show that the best method of IPD and CAP preventing are pneumococcal vaccinations. On the market for ages 23-valent polysaccharide vaccine (PPV23) is available covering close the 90% of IPD triggering stereotypes. Her role in preventing CAP is uncertain and the immunological answer after vaccination at older persons and after revaccination is weak. Widely discussed disadvantageous effects of growing old of the immunological system show on the benefit from applying the immunization inducing the immunological memory, i.e. of conjugated vaccines which are activating the T-dependent reply and are ensuring the readiness for the effective secondary response. Examinations so far conducted with conjugated 7-valent and 13-valent (PCV13) vaccines at persons in the age > 50 years are confirming these expectations. Also sick persons can take benefits from PCV13 applying back from so-called IPD risk groups in the age > 19 years. At these work research findings were described above PPV23 and PCV13 at adults and world recommendations of applying both vaccines in risk groups from 19 years up to the advanced years. Also Polish recommendations of optimum applying of these vaccines were presented. They are recommending applying PCV13 at first in them, while PPV23, if to her readings exist should be given to > or = 8 of weeks from PCV13. In persons > or = 19 years which earlier received 1 or should receive more PPV23 doses first PCV13 dose should be given after the year or later than the last PPV23 dose, and then again PPV23 > or = 8 of weeks from PCV13 and the second PPV23 dose not earlier than 5 years from last PPV23. If the PPV23 application seems to be justified, it is irrespective of the more previous state vaccination against pneumococci, PCV13 should be given to as first.

Abstract
There is a debate about the association between asthma and gastroesophageal and/or laryngopharyngeal reflux (LPR). Pharyngeal pH-monitoring is a new technique that allows a physician to assess whether reflux passes the upper esophageal sphincter barrier. The aim of the study was to assess the prevalence of LPR in children with difficult-to-treat asthma. The present study was an open, prospective one. A total of 21 subjects of the mean age 12.7 years were enrolled in the study. All children were asked to fill out a Reflux Symptoms Index questionnaire and a 24-h pharyngeal pH monitoring was performed, using the Dx-pH Measurement System. The LPR was diagnosed in 13 (61.9%) children. There was a positive correlation between LPR diagnosis and the degree of asthma control. The LPR was more frequent in children treated with a higher than lower doses of fluticasone (p = 0.019, OR = 17.3) and in those using montelukast compared with non-users (p = 0.008, OR = 19.0). The mean Reflux Symptoms Index score was almost twice greater in children with LPR than in those without it (13.2 vs. 6.8, respectively, p = 0.003). We conclude that the prevalence of laryngopharyngeal reflux in children with difficult-to-treat asthma is substantial.

Indirect population impact of universal PCV7 vaccination of children in a 2 + 1 schedule on the incidence of pneumonia morbidity in Kielce, Poland. Eur J Clin Microbiol Infect Dis 2012; 31:3023-8. [PMID: 22895889 DOI: 10.1007/s10096-012-1656-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2012] [Accepted: 05/15/2012] [Indexed: 10/28/2022]
Abstract
The aim of this study was an analysis of the population effects of a seven-valent pneumococcal conjugate vaccine (PCV7) on pneumonia incidence rates in the 5-year follow-up period after the introduction in 2006 of a universal PCV7 vaccination programme in the city of Kielce, Poland. Vaccinations were carried out according to a 2 + 1 schedule. The vaccination compliance rate amounted to approximately 99 %. The age groups 0-2, 30-49, 50-65 and 65+ years were analysed. The Cochran-Armitage test was used to investigate the significance of observed trends in pneumonia morbidity. The significance of deviations from a linear trend was also tested. The importance of the trend was confirmed by the Mantel test. Between 2005 and 2010, the greatest decline, 82.9 % (2005, 25.31/1,000; 2010, 4.34/1,000), in pneumonia morbidity was observed for children <2 years of age. In the 65+ years age group, this amounted to 43.5 %. Lesser declines, but still of statistical significance, were observed for the other age groups: 16.5 % in the 30-49 years group and 40.4 % in the 50-64 years group. All reductions are statistically significant and confirmed by the Mantel test. Five years after the introduction of a universal PCV7 vaccination programme in Kielce, Poland, its effectiveness in pneumonia prevention has been demonstrated in both the <2 years of age group and indirectly for other groups.

A case of relapsing-remitting neuroborreliosis? Challenges in the differential diagnosis of recurrent myelitis. Case Rep Neurol 2012; 4:47-53.

Abstract
We report the case of a 31-year-old woman with 4 episodes of myelitis with pleocytosis, a positive Borrelia burgdorferi serology with positive antibody indices, and full recovery each time after antibiotic and steroid treatment, suggesting neuroborreliosis. We nevertheless believe that recurrent neuroborreliosis is improbable based on the levels of the chemokine CXCL13 in cerebrospinal fluid and favor the diagnosis of post-infectious autoimmune-mediated transverse myelitis possibly triggered by an initial neuroborreliosis as the cause of the relapses observed in our patient. We demonstrate the diagnostic steps and procedures which were important in the differential diagnosis of this unusual and challenging case.

Abstract
BACKGROUND Optical coherence tomography can be used to assess retinal degeneration in multiple sclerosis (MS). Thinning of the retinal nerve fibre layer and macular thickness have been well characterized, but newer devices allow quantification of all retinal layers. OBJECTIVES The objective of this study was to evaluate the thickness of the paramacular retina, peripapillary retinal nerve fibre layer, and deeper paramacular layers in MS patient subgroups, using state-of-the-art optical coherence tomography. METHODS Using a Heidelberg Engineering Spectralis device, we performed paramacular volumetric retinal scans and circular peripapillary fibre-layer scans, manually segmenting different retinal layers into single horizontal foveal scans in 95 patients with definite MS (42 relapsing-remitting, 41 secondary progressive, 12 primary progressive), plus 91 age- and sex-matched controls. RESULTS Even without a history of optic neuritis, all MS subgroups had significant thinning of the peripapillary retinal nerve fibre layer, the paramacular retinal thickness and the retinal ganglion cell- and inner plexiform layer. Only in primary progressive MS was the inner nuclear layer significantly reduced. CONCLUSIONS Our findings indicate a primary retinal pathology involving the inner nuclear layer in primary progressive MS. Results in eyes without history of optic neuritis suggest possible subclinical episodes of optic neuritis or retrograde trans-synaptic degeneration of retinal ganglion cells and their axons.

Abstract
OBJECTIVE To determine the effectiveness of sequential therapy compared with standard triple therapy for Helicobacter pylori eradication in children. STUDY DESIGN In 107 children with H pylori infection confirmed with 2 of 3 tests ((13)C-urea breath test, histopathology, rapid urease test), we conducted a double-blind, randomized, controlled trial comparing a sequential treatment (amoxicillin and omeprazole for 5 days followed by clarithromycin, tinidazole, and omeprazole for 5 days) to a 7-day standard triple eradication regimen (amoxicillin and clarithromycin plus omeprazole) followed by placebo for 3 days. RESULTS In the experimental group (n=52) compared with the control group (n=51), there was a significant difference in the H pylori eradication rate at 6 to 8 weeks after the completion of treatment (primary outcome), as confirmed with negative results on (13)C-urea breath test (45/52 or 86.5% versus 35/51 or 68.6%; relative risk, 1.26; 95% CI, 1.02-1.60). Groups did not differ in any of the secondary outcomes (ie, adverse effects, the need for discontinuation of the H pylori therapy, compliance with therapy). CONCLUSIONS In children with H pylori infection, sequential eradication therapy compared with standard triple therapy resulted in a higher eradication rate, although the difference was of borderline statistical significance.

Abstract
BACKGROUND There are only a few studies on immune response to routine vaccinations in children with inflammatory bowel disease (IBD), despite a strong need for this kind of study. The aim of the study was to evaluate the immunogenicity of an inactivated hepatitis A vaccine (HAV) in IBD pediatric patients compared with healthy controls. METHODS This was an open, prospective, and controlled study on anti-HAV-negative children and adolescents age 2-18 years with IBD. HAV using 720 enzyme-linked immunosorbent assay (ELISA) units were administered at 0 months and at 6-12 months. Seroconversion and geometric mean titers were measured after each vaccine dose. The evidence of local and systemic adverse effects for 3 days after the first and second dose of vaccine was registered. RESULTS A total of 134 subjects (66 patients and 68 controls) completed the whole study course consisting of two doses of vaccine and six serum samples. There was no significant difference in the rate of seroconversion between IBD patients and controls when measured after the second dose of vaccine (97% versus 100%, P = 0.2407), but the rate was significantly lower in the IBD group when measured after the first dose (39% versus 64%, P = 0.00001). The mean geometric titers were statistically significantly lower in the IBD group than in the control group at all of the measured timepoints. There were no serious adverse events related to HAV during the study. CONCLUSIONS HAV is both immunogenic and safe in pediatric patients with IBD.

Abstract
In these article they made analysis of indirect, population effects of mass, free of charge, pneumococcal vaccinations (PCV7) on all-cause pneumonia incidence in Kielce, Poland. The strongest and significant fall (p=0.00079) in all-cause pneumonia incidence in the analyzed period 2005-2009 compared with remaining groups were observed in the group of children under 2 of years of life. He amounted to the 74% (around 25/1000 in 2005; 6/1000 in 2009). In the entire ancient group 0-29, embracing children under 2 yrs of life the fall of pneumonia incidence rate amounted to the 48% (from 2.8/1000 in 2005; 1.5/1000 in 2009). In the age 65+ group the fall in the incidence amounted to the 45% (19/1000 in 2005; <11/1000 in 2009 r.). At the moment they didn't observe, of such a fall in age groups 30-49 yrs and 50-64 yrs. Presented results are pointing population effectiveness of applied in Kielce mass vaccination in a 2+1 scheme. Analyzing only pneumonia requiring the hospitalization they tried at work to estimate, in the definitely simplified way, financial effects of mass pneumococcal vaccination in Kielce. Analysis showed at children up to 2 yrs frugalities of the row of the 174,420 zloty annually. In the group above 1 year of life analogous analysis showed frugalities of row 789,480 zloty. Results presented by us should, in our opinion, to induce decision-makers for free of charge mass pneumococcal vaccinations to entire Poland.

Abstract
Glycerol tetraethers with head-to-head isoprenoid 40-carbon chains that are typical of archaebacteria, in particular of methanogens, were identified in the polar lipids of sediments and petroleums. These structures are at least partially preserved in the subsurface beyond the stage of petroleum formation. Their identification provides further evidence that a significant part of geological organic matter derives from the lipids of membranes of microorganisms.
