RESUMO

BACKGROUND: Foreign body impaction is a frequent indication of urgent endoscopy. One of the reasons for impaction is eosinophilic oesophagitis (EE). To analyze characteristics of oesophageal foreign body impactions and their relationship with eosinophilic oesophagitis. METHODS: In this retrospective study, urgent endoscopies in a tertiary care centre were analyzed. We included all urgent endoscopies due to bolus and foreign body impactions performed between September 1st 2018 and September 1st 2020. We reviewed clinical data of all patients who were diagnosed with EE and compared it to impactions that were due to other motives. The mean follow-up time was 18.7 months. RESULTS: 693 urgent endoscopy procedures were performed. 239 (34%) of these were due to foreign body ingestion. Mean age of the patients was 63 years old and 135 (63%) were men. EE was diagnosed in 36 (17%) patients. The factors associated with EE were age, to be younger than 50 years (OR, 7.3; 95% CI, 1.1-48.4; p=0.04), asthma/rhinitis/atopic dermatitis (OR, 8.9; 95% CI, 2.3-35.3; p=0.002), findings in the endoscopy as trachealization (OR, 9.7; 95% CI, 1.3-70.9; p=0.03) and psychotropic/calcium channel blocker drugs (OR, 0.09; 95% CI, 0.009-0.9; p=0.04). 15 (7%) patients died. In 6 of them death was impaction-related. None patients with EE died. CONCLUSIONS: Foreign body impaction in the upper gastrointestinal tract due to EE is a frequent cause of urgent endoscopy. Being under 50 years of age, having asthma/rhinitis/atopic dermatitis, trachealization on the oesophagus and not taking psychotropic/calcium channel blocker drugs are factors associated with the diagnosis of EE. Mortality in the follow-up of patients without EE is important.

RESUMO

INTRODUCTION AND OBJECTIVES: We aimed to study the liver iron concentration in patients referred for hyperferritinemia to six hospitals in the Basque Country and to determine if there were differences between patients with or without metabolic syndrome. PATIENTS AND METHODS: Metabolic syndrome was defined by accepted criteria. Liver iron concentration was determined by magnetic resonance imaging. RESULTS: We obtained the data needed to diagnose metabolic syndrome in 276 patients; a total of 135 patients (49%), 115/240 men (48%), and 20/36 women (55.6%) presented metabolic syndrome. In all 276 patients, an MRI for the determination of liver iron concentration (mean±SD) was performed. The mean liver iron concentration was 30.83±19.38 for women with metabolic syndrome, 38.84±25.50 for men with metabolic syndrome, and 37.66±24.79 (CI 95%; 33.44-41.88) for the whole metabolic syndrome group. In 141 patients (51%), metabolic syndrome was not diagnosed: 125/240 were men (52%) and 16/36 were women (44.4%). The mean liver iron concentration was 34.88±16.18 for women without metabolic syndrome, 44.48±38.16 for men without metabolic syndrome, and 43.39±36.43 (CI 95%, 37.32-49.46) for the whole non-metabolic syndrome group. Comparison of the mean liver iron concentration from both groups (metabolic syndrome vs non-metabolic syndrome) revealed no significant differences (p=0.12). CONCLUSIONS: Patients with hyperferritinemia and metabolic syndrome presented a mildly increased mean liver iron concentration that was not significantly different to that of patients with hyperferritinemia and non-metabolic syndrome.

RESUMO

INTRODUCTION: Immunomodulators and biologics are two of the main drugs used for the treatment of inflammatory bowel disease (IBD). Some of these agents have been associated with certain infections and lymphoproliferative disorders, including Epstein-Barr virus (EBV) infection. Our aim was to determine the influence of immunosuppression in the EBV viral load in patients with IBD. MATERIALS AND METHODS: We prospectively included naïve patients with IBD who were starting immunosuppressive therapy in four IBD Units. All patients were assessed at baseline and four months after starting immunosuppression for clinical disease activity, biomarkers, EBV serology (IgM VCA, IgG VCA and IgG EBNA) and viral load. RESULTS: Thirty-two patients were included. At baseline, all patients showed positive results for IgG VCA or IgG EBNA with undetectable EBV viral load. No patient showed detectable EBV viral load after starting the immunosuppressive therapy. CONCLUSION: Immunosuppression did not influence on EBV viral load in the short-term in naïve IBD patients.

RESUMO

Background & aims. Hyperferritinemia (HF) is frequently present in patients with metabolic syndrome (MS). MS associated with HF is named dysmetabolic hyperferritinemia (DH). There are some publications that propose that DH is associated with a raised liveriron concentration (LIC). We studied the LIC in patients referred for HF to a secondary hospital to determine if there are differences between patients with or without MS. MATERIAL AND METHODS: We conducted a prospective study of 132 consecutive patients with HF from January to December 2010. The MS was defined by the International Diabetes Federation criteria (2005). LIC was determined by Magnetic resonance imaging (MRI). RESULTS: The number of patients for which there was enough data to determine MS was 97, out of which 54 had MS and 43 had no MS (NMS). In 54/97 patients, MRI for LIC determination was performed. From the MS group, 44 were men (27 underwent MRI) and 10 women (9 MRI). The mean LIC was 27.83 ± 20.90 ?mol/g for the MS group. In the NMS group, 36 were men (13 MRI), and 7 women (5 MRI). In 18 patients from the NMS group, LIC was determined by MRI. The mean LIC was 33.16 ± 19.61 ?mol/g in the NMS group. We compared the mean values of LIC from both groups (MS vs. NMS) and no significant differences were found (p = 0.067). CONCLUSION: Patients with DH present a mean LIC within normal values and their values do not differ from those of patients with HF but without MS.

RESUMO

A cohort study of patients included in the Basque Country colorectal cancer (CRC) screening programme was carried out to assess the risk of adenomatous polyps and CRC (P-CRC) associated with HFE gene mutations, with gender and with iron biomarkers (serum ferritin (SF), iron (Fe) and transferrin saturation index (TSI)). Among 432 included patients (mean age 59.8 years), 263 were men (60.9 %) and 169 women (39.1 %). P-CRC were identified in 221 patients (51.2 %) and no polyps (NP) in 211 patients (48.8 %). HFE mutations were identified in 43.8 % of the patients. C282Y/wt genotypic frequency was 6.8 % in the P-CRC group and 1.4 % in the NP group (p < 0.05). The allelic frequency was 3.8 versus 1.2 % (p < 0.05). For laboratory, all three iron biomarkers showed a statistically significant difference: mean Fe, 91.29 ± 34 for P-CRC and 80.81 ± 30.59 for NP group. Mean TSI for P-CRC was 24.95 ± 8.90 and 22.74 ± 8.79 for NP group. Mean SF 308.09 ± 536.32 for P-CRC and 177.55 ± 159.95 for NP group. In a multivariate logistic regression analysis, only male gender (odds ratio (OR) = 2.04, 1.29-3.22), SF (OR = 1.001, 1.0004-1.003) and Fe (OR = 1.01, 1.004-1.02) were related with the presence of CRC and adenoma. Men gender and raised serum iron biomarkers increase the risk of P-CRC.

RESUMO

BACKGROUND AND AIMS: There are limited data on clinical and phenotypic characteristics of outpatients referred for hyperferritinemia (HF). To determine the causes of HF in outpatients referred to a secondary hospital. MATERIAL AND METHODS: A prospective study of 132 consecutive patients with HF (> 200 µg/L, women; > 300 µg/L, men) was conducted from January-December 2010. RESULTS: Mean age, 54.42 years (SD: 13.47, range: 23-83); body mass index (BMI), 28.80 (SD: 3.96, 17-39); ferritin (SF), 579.54 ng/mL (SD: 296.575, 206-1668); transferrin saturation (TSI), 43.87% (SD: 14.09, 12-95); iron (Fe), 134 µg/dL (SD: 49.68, 55-322); overweight: 48.31%, and obese: 40.44% (89%), and most patients were men (108/132). Regarding HFE mutations, H63D/H63D genotype and H63D allele frequencies were 17.5% (vs. 7.76% in controls); and 36% (31% in controls) respectively. While 63.6% consumed no alcohol, 18.1% consumed ≥ 60 g/day, the mean being 20.83 (SD: 33.95, 0-140). Overall, 6/132 (4.5%) patients were positive for B or C hepatitis. Mean LIC by MRI was 36.04 (SD: 32.78, 5-210), 53 patients having normal concentrations (< 36 µmol/g), 22 (33%) iron overload (37-80), and 4 (5%) high iron overload (> 80). Metabolic syndrome (MS) was detected in 44/80 men (55%) and 10/17 women (59%). In this group, the genotype frequency of the H63D/H63D mutation was significantly higher than in controls-21.56% vs. 7.76%- (p = 0.011); the H63D allelic frequency was 42.15% in MS group and 31% in controls (p = 0.027). CONCLUSION: The H63D/H63D genotype and H63D allele predispose individuals to HF and MS. MRI revealed iron overload in 33% of patients.

RESUMO

INTRODUCTION: Although there is literature on sexuality in gender dysphoria, few studies have been done prior to genital sex reassignment surgery (SRS). AIMS: To evaluate the perception of sexual QoL in gender-dysphoric patients before genital SRS and the possible factors associated to this perception. METHODS: The final sample consisted of 67 male-to-female and 36 female-to-male gender-dysphoric adults consecutively attended in a gender unit who had not undergone genital SRS; 39.8% was receiving cross-sex hormonal treatment, and 30.1% had undergone breast augmentation or reduction. Sexual QoL was assessed using the sexual activity facet of the World Health Organization Quality of Life (WHOQOL)-100. Sociodemographic (age, gender, partner relationship) and clinical data (being on hormonal treatment and having undergone any breast surgery) were recorded from the clinical records. Depressive symptoms were assessed using the negative feelings facet of the WHOQOL-100. Personality was assessed using the Revised NEO-Five Factor Inventory. MAIN OUTCOME MEASURES: Sexual QoL, negative feelings, hormonal treatment, partner relationship, personality. RESULTS: The mean score of the sexual facet was 10.01 (standard deviation = 4.09). More than 50% of patients rated their sexual life as "poor/dissatisfied" or "very poor/very dissatisfied," around a quarter rated it as "good/satisfied" or "very good/very satisfied," and the rest had a neutral perception. Three variables were significantly associated with a better sexual QoL: less negative feelings (ß = -0.356; P < 0.001), being on hormonal treatment (ß = 0.216; P = 0.018), and having a partner (ß = 0.206; P = 0.022). Age, sex, having undergone some breast surgery, and personality factors were not associated with their perception. CONCLUSION: This study indicates that before genital SRS, about half of gender-dysphoric subjects perceived their sexual life as "poor/dissatisfied" or "very poor/very dissatisfied." Moreover, receiving hormonal treatment, low negative feelings, and having a partner are related to a better subjective perception of sexual QoL.

RESUMO

Colorectal adenomas are precursors of most colorectal cancers and are consequently a surrogate endpoint for assessing the efficacy of chemopreventive agents. Cyclooxygenase-2 (COX-2) levels have been found to be increased in a significant number of colorectal carcinomas and adenomas. COX-2 overexpression is linked to carcinogenesis due to increased production of prostaglandins, which seem to play an important role in angiogenesis, cell proliferation and migration, as well as in apoptosis. These data support the use of acetylsalicylic acid (AAS) or aspirin, a COX-2 inhibitor, as an effective agent in colorectal cancer prevention. Several cohort and case control studies have shown that regular use of aspirin reduces the risk of colorectal cancer by approximately 50%. However, randomized controlled trials of aspirin report discrepant results, although there is an decrease in the relative risk of adenoma recurrence of approximately 17%. To date, although there is compelling evidence that the use of aspirin protects against adenoma and colorectal cancer, the optimal dose and duration of aspirin required to obtain this effect remain to be defined. Probably, the longer the treatment duration--even for more than 10 years--and possibly with higher doses, the greater the protective effects of aspirin. Finally, these benefits need to be considered in the context of all of the health effects of prolonged aspirin use, both positive and negative.

RESUMO

BACKGROUND: The significance of H63D homozygosity remains uncertain, although it is associated with a tendency for patients to develop iron overload. AIMS: To study the prevalence of homozygotic H63D mutation in patients with phenotypic hemochromatosis (PH) and to compare the results with those of the general population and with patients with porphyria cutanea tarda (PCT) in the Basque Country, Spain. A secondary aim was to evaluate the differences in phenotypic expression and liver injury according to different genotypes in the PH cohort. METHODS: Mutations of the HFE gene were obtained by polymerase chain reaction (PCR). Forty consecutive patients diagnosed with PH, 116 controls and 54 patients with PCT were included in the study. We performed liver biopsies, measured liver iron concentration (LIC), by atomic spectrophotometry, serum ferritin and transferrin saturation, and compared the histology according to the genotype. RESULTS: The H63D homozygote mutation was identified in 7.76% of the control group, in 7.50% of the PH group, and in 11.11% of patients with PCT (P > 0.05). The C282Y/C282Y mutation was present in 50% of patients with PH, and LIC was identified in 15/20. The LIC in C282Y/C282Y patients was higher than in H63D/H63D patients (P = 0.26), while H63D homozygosis caused greater iron overload in PH patients than other genotypes. All the C282Y/C282Y genotype patients had elevated serum ferritin and transferrin saturation. The H63D homozygotes had high ferritin, but two out of three had normal transferrin saturation. Six of the eight patients with high-grade fibrosis and genetic study results were found to be C282Y/C282Y. CONCLUSIONS: The prevalence of H63D mutation in patients with PH in our region does not differ from that of the general Basque population.
