RESUMEN

Whipple disease is an infection caused by the bacterium Tropheryma whipplei. Due to its unspecific clinical symptoms, it is difficult to diagnose and often remains undetected for a long time. The case of a patient who presented with acute intestinal symptoms to the authors' department is reported. The diagnosis of classic Whipple disease was established. The symptoms subsided under antibiotic therapy. Complications in the form of immune reconstitution inflammatory syndrome (IRIS) occurred, requiring immunosuppressive treatment.

RESUMEN

A 10-year-old girl with juvenile idiopathic arthritis in remission presented with a flare of her arthritis. All her joints responded to treatment except the right knee, despite the use of disease-modifying antirheumatic drugs, non-steroidal anti-inflammatory medication and high-dose cortisone. A magnetic resonance imaging scan showed a knee densely packed with rice bodies. After surgical removal of the rice bodies the inflammation settled once again, and the patient remains well on her usual medication.

RESUMEN

AIM: The data on health management programmes in German companies show quite heterogeneous results. The aim of the study was to gain more transparency into the cause of these discrepancies as well as information on factors influencing the willingness of companies to implement such programmes. METHODS: Based on a systematic database search, relevant studies were identified and comparative analysis of their contents was carried out. RESULTS: The existing studies on the health management programmes in German companies reveal significant discrepancies in terms of their research question, representativeness, approach and design. Nevertheless, they do reveal certain trends identifying significant factors that influence the willingness of companies to implement such programmes. CONCLUSION: In the design of future studies to analyse the distribution of corporate health management programmes, there is a need to agree on common definitions and data collection methods and how the results are to be categorised. When evaluating the effects of corporate programmes, the quantitative data would need to be supplemented with qualitative data that would be capable of identifying how such programmes are implemented and the associated organisation-specific cultural patterns.

RESUMEN

This work evaluated the ability of the probiotic Streptococcus thermophilus CRL1190 strain and its exopolysaccharides to adhere to gastric mucosa. Probiotic bacteria attachment to the human stomach epithelium was confirmed in human stomach tissue samples and the gastric epithelial cell line AGS. In addition, it was demonstrated that S. thermophilus CRL1190 strain reduced Helicobacter pylori adhesion and attenuated inflammatory response in AGS cells. This is the first demonstration of the capacity of S. thermophilus CRL1190 to adhere to the stomach gastric mucosa, and improve protection against H. pylori through the reduction of its adhesion and the modulation of the inflammatory response. Therefore, S. thermophilus CRL1190 fermented milk is a good candidate for further in vivo studying of the protective effect of functional food against H. pylori infection and gastric inflammatory damage.

RESUMEN

Background Systemic lupus erythematosus (SLE) is a life-threatening multisystem autoimmune disease that is more severe in patients of African ancestry and children, yet pediatric SLE on the African continent has been understudied. This study describes a cohort of pediatric SLE (PULSE) patients in South Africa. Methods Patients with a diagnosis of SLE (1997 American College of Rheumatology criteria) diagnosed prior to age 19 years in Cape Town, South Africa, were enrolled in this cross-sectional study from September 2013 to December 2014. Information on clinical and serological characteristics was extracted from medical records. Results were compared to a well-described North American pediatric SLE cohort. Results Seventy-two South African patients were enrolled in the study; mean age 11.5 years; 82% were girls. The racial distribution was 68% Coloured, 24% Black, 5% White and 3% Asian/Indian. Most patients presented with severe lupus nephritis documented by renal biopsy (61%). Of patients with lupus nephritis, 63% presented with International Society of Nephrology/Renal Pathology Society class III or IV. Patients in the PULSE cohort were more likely to be treated with cyclophosphamide, methotrexate and azathioprine. The PULSE cohort had high disease activity at diagnosis (mean Systemic Lupus Erythematosus Disease Activity Index-2K (SLEDAI-2K) 20.6). The SLEDAI-2K at enrolment in the PULSE cohort (5.0) did not differ from the North American pediatric SLE cohort (4.8). Sixty-three per cent of the PULSE cohort had end organ damage with Systemic Lupus International Collaborating Clinics Damage Index (SLICC-DI) score >0 (mean SLICC-DI 1.9), compared to 23% in a previously reported US cohort. Within the PULSE cohort, nine (13%) developed end-stage renal disease with six (8%) requiring transplant, strikingly higher than North American peers (transplant rate <1%). Conclusions The PULSE cohort had highly active multiorgan disease at diagnosis and significant disease damage at enrolment in the South African registry. South African patients have severe lupus nephritis and poor renal outcomes compared to North American peers. Our study revealed a severe disease phenotype in the PULSE cohort resulting in poor outcomes in this high-risk population.

RESUMEN

In June 2015 the scientific academies "Leopoldina" and "acatech" and the union of the German academies of sciences and humanities published a statement on public and global health in Germany. The statement contains many valuable albeit generic and well-known recommendations. The few specific recommendations focus on centralizing research while weakening the role of universities and on the relative increase of research on public health genomics. These recommendations are not based on empirical or theoretical analyses and risk subverting successful developments of the recent past. To actually strengthen public and global health in Germany the existing institutions need to be backed up while designated funding of public and global health needs to be extended.

RESUMEN

BACKGROUND: Association studies have implicated the glycosaminoglycan hyaluronan (hyaluronic acid, HA) and its degrading enzymes the hyaluronidases in tumour progression and metastasis. Oligosaccharides of degraded HA have been ascribed a number of biological functions that are not exerted by high-molecular-weight HA (HMW-HA). However, whether these small HA oligosaccharides (sHA) have a role in tumour progression currently remains uncertain due to an inability to analyse their concentration in tumours. METHODS: We report a novel method to determine the concentration of sHA ranging from 6 to 25 disaccharides in tumour interstitial fluid (TIF). Levels of sHA were measured in TIF from experimental rat tumours and human colorectal tumours. RESULTS: While the majority of HA in TIF is HMW-HA, concentrations of sHA up to 6 µg ml(-1) were detected in a subset of tumours, but not in interstitial fluid from healthy tissues. In a cohort of 72 colorectal cancer patients we found that increased sHA concentrations in TIF are associated with lymphatic vessel invasion by tumour cells and the formation of lymph node metastasis. CONCLUSIONS: These data document for the first time the pathophysiological concentration of sHA in tumours, and provide evidence of a role for sHA in tumour progression.

RESUMEN

Signal transducer and activator of transcription 3 (STAT3) is altered in several epithelial cancers and represents a potential therapeutic target. Here, STAT3 expression, activity and cellular functions were examined in two main histotypes of esophageal carcinomas. In situ, immunohistochemistry for STAT3 and STAT3-Tyr705 phosphorylation (P-STAT3) in esophageal squamous cell carcinomas (ESCC, n=49) and Barrett's adenocarcinomas (BAC, n=61) revealed similar STAT3 expression in ESCCs and BACs (P=0.109), but preferentially activated P-STAT3 in ESCCs (P=0.013). In vitro, strong STAT3 activation was seen by epidermal growth factor (EGF) stimulation in OE21 (ESCC) cells, whereas OE33 (BAC) cells showed constitutive weak STAT3 activation. STAT3 knockdown significantly reduced cell proliferation of OE21 (P=0.0148) and OE33 (P=0.0243) cells. Importantly, STAT3 knockdown reduced cell migration of OE33 cells by 2.5-fold in two types of migration assays (P=0.073, P=0.015), but not in OE21 cells (P=0.1079, P=0.386). Investigation of transcriptome analysis of STAT3 knockdown revealed a reduced STAT3 level associated with significant downregulation of cell cycle genes in both OE21 (P<0.0001) and OE33 (P=0.01) cells. In contrast, genes promoting cell migration (CTHRC1) were markedly upregulated in OE21 cells, whereas a gene linked to tight-junction stabilization and restricted cell motility (SHROOM2) was downregulated in OE21 but upregulated in OE33 cells. This study shows frequent, but distinct, patterns of STAT3 expression and activation in ESCCs and BACs. STAT3 knockdown reduces cell proliferation in ESCC and BAC cells, inhibits migration of BAC cells and may support cell migration of ESCC cells. Thereby, novel STAT3-regulated genes involved in ESCC and BAC cell proliferation and cell migration were identified. Thus, STAT3 may be further exploited as a potential novel therapeutic target, however, by careful distinction between the two histotypes of esophageal cancers.

RESUMEN

The gastric hormone ghrelin is known as an important factor for energy homeostasis, appetite regulation and control of body weight. So far, ghrelin has mainly been examined as a serological marker for gastrointestinal diseases, and only a few publications have highlighted its role in local effects like mucus secretion. Ghrelin can be regarded as a gastroprotective factor, but little is known about the distribution and activity of ghrelin cells in pathologically modified tissues. We aimed to examine the morphological changes in ghrelin expression under several inflammatory, metaplastic and carcinogenic conditions of the upper gastrointestinal tract. In particular, autoimmune gastritis showed interesting remodeling effects in terms of ghrelin expression within neuroendocrine cell hyperplasia by immunohistochemistry. Using confocal laser microscopy, the gastrin/cholecystokinin receptor (CCKB) could be detected on normal ghrelin cells as well as in autoimmune gastritis. Functionally, we found evidence for a physiological interaction between gastrin and ghrelin in a primary rodent cell culture model. Additionally, we gathered serological data from patients with different basic gastrin levels due to long-term autoimmune gastritis or short-term proton pump inhibitor treatment with slightly reactive plasma gastrin elevations. Total ghrelin plasma levels showed a significantly inverse correlation with gastrin under long-term conditions. Autoimmune gastritis as a relevant condition within gastric carcinogenesis therefore has two effects on ghrelin-positive cells due to hypergastrinemia. On the one hand, gastrin stimulates the proliferation of ghrelinpositive cells as integral part of neuroendocrine cell hyperplasia, while on the other hand, plasma ghrelin is reduced by gastrin and lost in pseudopyloric and intestinal metaplastic areas. Ghrelin is necessary for the maintenance of the mucosal barrier and might play a role in gastric carcinogenesis, if altered under these pre neoplastic conditions.

RESUMEN

HISTORY AND ADMISSION FINDINGS: An 81-year-old man presented with jaundice and a pancreatic tumor. 6 years ago transperitoneal nephrectomy had been performed because of a clear cell renal cancer (pT3b pN0 pM0). INVESTIGATIONS: Laboratory tests showed normocytic anemia and signs of cholestasis. Abdominal ultrasonography revealed a well-defined mass of the head of the pancreas with a diameter of about 4 cm, and a previously diagnosed adrenal mass which had slightly increased in size. Contrast-enhanced ultrasound demonstrated a hyperenhancing of the pancreatic mass, untypical for primary adenocarcinoma of the pancreas. Endoscopic ultrasound-guided fine-needle aspiration disclosed a metastasis of the previously resected renal cancer. TREATMENT AND COURSE: Bilary spincterotomy and stent insertion were performed. Because of proven pancreatic metastasis and suspected adrenal metastasis of renal cancer palliative treatment with multi-targeted receptor tyrosine kinase inhibitor sunitinib was initiated. CONCLUSION: Renal cell carcinomas are the most common primary tumors leading to pancreatic metastasis. In contrast to ductal adenocarcinoma pancreatic metastasis shows hyperenhancement when examined by using contrast-enhanced ultrasonography. Endoscopic ultrasound-guided fine-needle aspiration helps to confirm the suspected diagnosis.

RESUMEN

Until recently, two major types of colorectal epithelial polyps were distinguished: the adenoma and the hyperplastic polyp. While adenomas - because of their cytological atypia - were recognized as precursor lesions for colorectal carcinoma, hyperplastic polyps were perceived as harmless lesions without any potential for malignant progression, mainly because hyperplastic polyps lack cytological atypia. Meanwhile, it is evident that the lesions formerly classified as hyperplastic represent a heterogeneous group of polyps, some of which exhibit a significant risk of neoplastic progression. These lesions show characteristic epigenetic alterations not commonly seen in colorectal adenomas and progress to colorectal carcinoma via the so-called serrated pathway (CIMP pathway). This group of polyps is comprised not only of hyperplastic polyps, but also of sessile serrated adenomas (SSA), traditional serrated adenomas (TSA) and mixed polyps, showing serrated and "classical" adenomatous features. In a consensus conference of the working group of gastroenterological pathology of the German Society of Pathology, standardization of nomenclature and diagnostic criteria as well as recommendations for clinical management of these serrated polyps were formulated and are presented herein.

RESUMEN

HISTORY AND ADMISSION FINDINGS: A 38-year-old woman (Pt. 1) and a 30-year-old man (Pt. 2) had been admitted, over a period of two months to the emergency unit. Pt 1. had complained of spasmodic pain with nausea and vomiting. A mass was palpated in the left upper abdominal quadrant. Pt. 2 had signs suggesting appendicitis, with pain in the right lower abdominal quadrant. INVESTIGATIONS: Abdominal ultrasound showed an intussusception with a typical multilayered bowel wall ("target-like" or "bull's eye") sign in both patients. The man also had a normally appearing appendix and enlarged mesenteric lymph nodes. TREATMENT, COURSE AND DIAGNOSIS: Pt. 1 had a laparotomy, which showed a leiomyoma of the small bowel. After resection the further course was uneventful. The intussusception of the 30-year-old man resolved spontaneously during the ultrasound examination. Further investigation revealed celiac disease. CONCLUSIONS: Intussusception is a possible cause of acute abdominal pain in adults. Ultrasonography should be the initial diagnostic investigation. Transient intussusceptions are seen in adults with celiac disease, in which case nonoperative treatment is possible.

RESUMEN

Root extract from Pelargonium sidoides DC is used therapeutically as antimicrobial agent against infections of the respiratory system. In order to elucidate possible modes of actions we investigated the influence of P. sidoides root extract on microbial adhesion with Helicobacter pylori as model microorganism, a germ with a strong adherence to human stomach tissue. In an in-situ anti-adhesion assay intact human stomach tissue from patient resectates was incubated with fluorescent-labelled bacteria. Epithelial adhesion occurred in untreated samples and was quantified by fluorescent microscopy. Pre-treatment of the bacteria with Pelargonium extract showed good anti-adhesive activity. The antiadhesive effect was clearly dose-dependent in a range from 0.001 to 10 mg/ml. Within agar diffusion-test the extract had no direct cytotoxicity against H. pylori. The results show that the root extract from Pelargonium sidoides is a potent anti-adhesive agent against H. pylori and could therefore be a useful choice to avoid the first step of a bacterial infection.

RESUMEN

Solitary fibrous tumors (SFT) are rare, mostly fibroblastic tumors usually situated in the pleura. Extrapleural manifestations have been described. However, the oral cavity is an uncommon localisation of this tumor. We report the very unusual case of an SFT affecting the tongue that could be removed completely because of its clear delineation. Intraoperative incisional biopsies were used to exclude malignancy. For definitive classification of the tumor, additional histopathologic examinations had to be carried out. Because SFT exhibit malignant behavior only in exceptional cases and their recurrence after complete removal has never been encountered, surgery can focus on the preservation of undisturbed function of the tongue.

RESUMEN

OBJECTIVES: To review the presentation and characteristics of children with systemic lupus erythematosus (SLE). METHODS: The records of children with sufficient American College of Rheumatology (ACR) criteria for SLE treated by the renal units of the Johannesburg and Chris Hani Baragwanath hospitals, and the arthritis clinic of the Johannesburg Hospital between January 1974 and March 2000 were reviewed. The clinical presentation, age distribution and race were examined. RESULTS: A total of 36 children met the criteria. There were 26 girls and 10 boys, with a mean age of 11.5 and 10.2 years respectively. The male-to-female ratio was 1:2.6 overall, with a ratio of 1:1.2 under 10 years and 1:4 over 10 years. There were 15 white, 2 Indian and 5 coloured patients. The 14 black patients all presented after 1986. Rashes were found to be the commonest clinical feature present at the time of diagnosis, followed by polyarthritis and renal pathology. Constitutional symptoms were common, as were generalised lymphadenopathy and hepatosplenomegaly, while neurological, pulmonary and cardiac signs and symptoms were less common. Renal disease was present in 58% of patients on presentation. CONCLUSION: There is a diverse array of presenting features in childhood SLE. There has been increased recognition of the disease in young black South Africans since 1986.

RESUMEN

BACKGROUND: Helicobacter pylori-associated atrophy of the gastric corpus is associated with the presence of anti-canalicular autoantibodies. Also, long-term profound acid suppression in H. pylori-infected subjects may cause atrophic corpus gastritis. AIM: To investigate whether long-term acid suppression by omeprazole leads to antigastric autoantibodies. METHODS: Fifty patients, of which 34 H. pylori-positive on entry of the study, were treated with omeprazole (20-40 mg once daily) for reflux oesophagitis, and were evaluated for anti-gastric autoantibody responses by immunohistochemistry before and after treatment. H. pylori was not eradicated and patients were followed for an average of 6.6 years (range 3-14.1 years). In addition to immunohistochemistry, anti-H(+), K(+)-ATPase reactivity was assessed by Western blot in paired sera of 41 patients (26 H. pylori-positive and 15 uninfected) and results are critically evaluated. RESULTS: In immunohistochemistry, all patients were negative for anti-canalicular autoantibodies when omeprazole therapy started, except for two patients with corpus-predominant gastritis in the presence of H. pylori. One patient, who was H. pylori-negative, newly developed an anti-canalicular antibody response during therapy. CONCLUSIONS: Our results indicate that, as compared with non-infected patients, long-term profound acid suppression therapy in H. pylori-infected gastro-oesophageal reflux disease patients does not increase or accelerate gastric autoimmunity.

RESUMEN

Several crude and purified polysaccharides from black currant seeds (Ribes nigrum L.) have been isolated, analysed and examined on their effects against Helicobacter pylori in in situ adhesion studies on sections of human gastric mucosa. After pre-treatment of Helicobacter pylori with 0.01 to 0.1 % solutions of the isolated raw polysaccharide (RPS), the epithelial binding of the bacteria was considerably reduced in a concentration-dependent manner, as compared with a non-treated control suspension. Preincubation of the mucosal sections with 0.1 % solutions did not result in a reduced binding of non-treated bacteria. An anion-exchange fraction of RPS eluted with 0.1 M phosphate buffer exhibited a comparable, concentration-dependent reduction of adhesion, whereas the water-eluted fraction was ineffective at the respective concentrations. Both subfractions consisted of similar 1,3-linked galactans, decorated with side chains possessing 1,4-galacturonic acid, galactose and arabinose residues. Molecular weight profiling by GPC revealed that the antiadhesive activity of the buffer eluate correlated with high molecular weight components ranging from about 1000 Da to 340 kDa, whereas the ones of the inactive water eluate had molecular weights of about 100 and 25 kDa, respectively. None of the active fractions revealed inhibitory effects on bacterial growth in vitro. We conclude that acidic, high molecular weight galactans are responsible for the antiadhesive qualities of black currant seed extracts and that these polymers are able to block Helicobacter surface receptors, thus inhibiting their interaction with specific binding factors located on human gastric epithelia.
