RESUMEN

BACKGROUND & OBJECTIVES: Patients with non-alcoholic fatty liver disease (NAFLD) have high prevalences of hypertension (HTN), type 2 diabetes mellitus (T2DM), and cardiovascular disease (CVD), and vice versa. The mechanism of this development is unknown but appears to be related to an underlying metabolic derangement that affects multiple organs. This study aimed to determine the prevalences of these conditions in patients with diagnosed NAFLD. METHODS: Our cohort study aimed to determine the prevalences of HTN, T2DM, and CVD in NAFLD patients registered in the liver database of the University of Puerto Rico School of Medicine; this information is recorded in their medical records. Patients whose liver disease had a different etiology were excluded. The study was approved by the UPR Medical Sciences Campus Institutional Review Board. RESULTS: Our final sample consisted of 141 NAFLD patients; 64.5% (n = 91) of them were females. The average age was 69 (±10.2 years). The prevalences of HTN, T2DM, and CVD were 53.9%, 57.5%, and 7.8%, respectively. In patients with NAFLD, there was a significant association between T2DM and being 65 years old or older (P < 0.001). CONCLUSION: Our data indicate that HTN and T2DM are highly prevalent in NAFLD patients in PR; however, CVD prevalence was lower than expected. Additional, studies are required to further define the associations. We recommend metabolic condition screening for all NAFLD patients.

RESUMEN

The aim of this study was to analyze the profiles of IgG subclasses in COVID-19 convalescent Puerto Rican subjects and compare these profiles with those of non-infected immunocompetent or immunocompromised subjects that received two or more doses of an mRNA vaccine. The most notable findings from this study are as follows: (1) Convalescent subjects that were not hospitalized developed high and long-lasting antibody responses. (2) Both IgG1 and IgG3 subclasses were more prevalent in the SARS-CoV-2-infected population, whereas IgG1 was more prevalent after vaccination. (3) Individuals that were infected and then later received two doses of an mRNA vaccine exhibited a more robust neutralizing capacity against Omicron than those that were never infected and received two doses of an mRNA vaccine. (4) A class switch toward the "anti-inflammatory" antibody isotype IgG4 was induced a few weeks after the third dose, which peaked abruptly and remained at high levels for a long period. Moreover, the high levels of IgG4 were concurrent with high neutralizing percentages against various VOCs including Omicron. (5) Subjects with IBD also produced IgG4 antibodies after the third dose, although these antibody levels had a limited effect on the neutralizing capacity. Knowing that the mRNA vaccines do not prevent infections, the Omicron subvariants have been shown to be less pathogenic, and IgG4 levels have been associated with immunotolerance and numerous negative effects, the recommendations for the successive administration of booster vaccinations to people should be revised.

RESUMEN

OBJECTIVE: Past studies have demonstrated that women with inflammatory bowel disease (IBD) have a higher risk of gynecological conditions than do women without it. We aimed to characterize the gynecological histories of Hispanic Women living in Puerto Rico with IBD. METHODS: We identified women, aged 21 to 55 years, with a confirmed IBD diagnosis and receiving follow-up care from the University of Puerto Rico IBD clinics from 2017 through 2020. A questionnaire was administered to acquire sociodemographics, family history, past medical history, IBD diagnosis, and gynecologic aspects. RESULTS: One hundred eighty-six women were recruited. Fifty-three (28%) patients had ulcerative colitis, while 133 (72%) had Crohn's disease. Fifty-six percent of all the participants had a chronic illness in addition to than their IBD. Seventy-four out of 186 patients reported having had at least 1 late period within the last 12 months. Fifty-three (28%) described their period patterns as irregular. Thirty-nine (21%) of the patients reported having been vaccinated against human papillomavirus (HPV), and 8 (4%) had been infected by it. Nine out of 186 (5%) patients reported suffering from infertility. CONCLUSION: The results showed that our Hispanic patients (living in Puerto Rico) had a prevalence of irregular menstrual cycles that was similar to that observed in other populations. On the other hand, the presence of HPV, infertility, and cervical cancer were lower and the frequency of Papanicolaou smears performed higher than what has been seen in the continental United States, suggesting that this topic should be investigated in future studies.

RESUMEN

Diet has been increasingly shown to be of therapeutic benefit for patients with inflammatory bowel diseases (IBD), especially Crohn's disease (CD). Yet dietary guidelines are nonexistent. Moreover, diets tailored to Puerto Ricans with IBD living on the island, have not been developed and tested. The rising prevalence of IBD in Puerto Rico warrants exploring the use of diet as part of the treatment strategies for these patients [1]. Here, we describe the study design of "Dieta Anti-Inflamatoria" or DAIN, a parallel two-arm randomized pilot trial aiming at testing the efficacy of IBD-Anti-inflammatory diet (IBD-AID) adapted for adults with CD living in Puerto Rico (clinical trial registration number: NCT05627128). We tailored the IBD-AID to the local cuisine preferences and food availability by creating and adapting recipes consistent with the IBD-AID principles [2,3]. In focus groups with a Community Research Advisory Panel and one-on-one consultations with implementation experts, we identified several aspects of the intervention to adapt before the implementation. The objectives of the stakeholder/expert-informed adaptation were to improve feasibility and compliance while developing the culturally tailored dietary intervention. DAIN was designed for adults living in Puerto Rico with CD and geared to be affordable, appropriate, and acceptable for patients with mild-to-moderate CD. The significance of this work is the validation of culturally appropriate nutritional guidelines to help manage CD symptoms. DAIN provides a blueprint for a comprehensive nutritional program that can be adapted to regional preferences and local food availability allowing wider implementation of diet as an adjunct treatment in diverse clinical settings.

RESUMEN

PURPOSE: The aim of this study was to determine ostomy-related quality of life (QOL) in Hispanic Puerto Ricans living with an enteral stoma and inflammatory bowel disease (IBD). We analyzed possible associations between QOL and sex, diagnosis, and type and duration of stoma. DESIGN: Prospective cohort study. SUBJECTS AND SETTINGS: The sample comprised 102 adults living with IBD and an ostomy; 60 of 101 (59.4%) were males, 44 of 102 (43.1%) had Crohn's disease, and 60 of 102 (58.9%) had an ileostomy. Participants were receiving care at the Center for IBD of the University of Puerto Rico in San Juan, Puerto Rico, between January 2012 and December 2014. METHODS: One-hundred two adults Puerto Ricans with IBD completed the Stoma Quality of Life (Stoma-QOL) questionnaire. Data were analyzed using frequency distributions for categorical variables and summary statistics for continuous variables. Independent-group t test and one-way analysis of variance, with the post hoc Tukey test, were used to determine group differences for the variables of age, sex, civil status, time living with an ostomy, type of ostomy, and IBD diagnosis. Results were analyzed according to the number of responses to each variable; the denominator varied for some variables. RESULTS: Having an ostomy for more than 40 months was significantly associated with a higher QOL score (59.0 vs 50.7; P = .05). Males had significantly higher scores than females (59.94 vs 50.23; P = .0019). Age, IBD diagnosis, and type of ostomy were not associated with the Stoma-QOL scores. CONCLUSIONS: The achievement (over 40 months) to attain improved ostomy-related QOL suggests that early training in the care of the ostomy and advanced planning when leaving home may enhance ostomy-related QOL. Lower QOL in women may represent an opportunity for a sex-specific educational intervention.

RESUMEN

Inflammatory bowel diseases (IBDs) are chronic conditions of unknown cause or cure. Treatment seeks to reduce symptoms and induce and maintain remission. Many patients have turned to alternatives, such as cannabis, to alleviate living with IBD. This study reports the demographics, prevalence, and perception on cannabis use of patients attending an IBD clinic. Patients agreed to participate and completed an anonymous survey during their visit or online. Descriptive analysis, Fisher's exact test, and Wilcoxon-Mann-Whitney rank-sum test were used. One hundred and sixty-two adults (85 males, 77 with CD) completed the survey. Sixty (37%) reported use of cannabis, of which 38 (63%) used it to relieve their IBD. A value of 77% reported low to moderate knowledge about cannabis, and 15% reported little to no knowledge. Among cannabis users, 48% had discussed use with their physician, but 88% said they would feel comfortable discussing medical cannabis for IBD. Most saw improvement of their symptoms (85.7%). A considerable number of patients with IBD use medical cannabis for their disease, unknown to their physician. The study reinforces the importance that physicians understand the role of cannabis in the treatment of IBD in order to appropriately counsel patients.

RESUMEN

Hermansky-Pudlak syndrome (HPS) types 1 and 4 are caused by defective vesicle trafficking. The mechanism for Crohn's disease-like inflammation, lung fibrosis, and macrophage lipid accumulation in these patients remains enigmatic. The aim of this study is to understand the cellular basis of inflammation in HPS-1. We performed mass cytometry, proteomic and transcriptomic analyses to investigate peripheral blood cells and serum of HPS-1 patients. Using spatial transcriptomics, granuloma-associated signatures in the tissue of an HPS-1 patient with granulomatous colitis were dissected. In vitro studies were conducted to investigate anti-microbial responses of HPS-1 patient macrophages and cell lines. Monocytes of HPS-1 patients exhibit an inflammatory phenotype associated with dysregulated TNF, IL-1α, OSM in serum, and monocyte-derived macrophages. Inflammatory macrophages accumulate in the intestine and granuloma-associated macrophages in HPS-1 show transcriptional signatures suggestive of a lipid storage and metabolic defect. We show that HPS1 deficiency leads to an altered metabolic program and Rab32-dependent amplified mTOR signaling, facilitated by the accumulation of mTOR on lysosomes. This pathogenic mechanism translates into aberrant bacterial clearance, which can be rescued with mTORC1 inhibition. Rab32-mediated mTOR signaling acts as an immuno-metabolic checkpoint, adding to the evidence that defective bioenergetics can drive hampered anti-microbial activity and contribute to inflammation.

RESUMEN

Management of inflammatory bowel disease (IBD) often relies on biological and immunomodulatory agents for remission through immunosuppression, raising concerns regarding the SARS-CoV-2 vaccine's effectiveness. The emergent variants have hindered the vaccine neutralization capacity, and whether the third vaccine dose can neutralize SARS-CoV-2 variants in this population remains unknown. This study aims to evaluate the humoral response of SARS-CoV-2 variants in patients with IBD 60 days after the third vaccine dose [BNT162b2 (Pfizer-BioNTech) or mRNA-1273 (Moderna)]. Fifty-six subjects with IBD and 12 healthy subjects were recruited. Ninety percent of patients with IBD (49/56) received biologics and/or immunomodulatory therapy. Twenty-four subjects with IBD did not develop effective neutralizing capability against the Omicron variant. Seventy percent (17/24) of those subjects received anti-tumor necrosis factor therapy [10 = adalimumab, 7 = infliximab], two of which had a history of COVID-19 infection, and one subject did not develop immune neutralization against three other variants: Gamma, Epsilon, and Kappa. All subjects in the control group developed detectable antibodies and effective neutralization against all seven SARS-CoV-2 variants. Our study shows that patients with IBD might not be protected against SARS-CoV-2 variants, and more extensive studies are needed to evaluate optimal immunity.

RESUMEN

ABSTRACT: The aim of the present study was to describe the epidemiological and clinical characteristics of inflammatory bowel disease (IBD), including medical and surgical treatments, in several countries in Latin America and the Caribbean.IBD is recognized as a global health problem because its incidence and prevalence have increased significantly over the last few years.This multicenter retrospective cohort study included 4714 patients with IBD diagnosed from 9 countries in Latin America and the Caribbean: Colombia, Cuba, Dominican Republic, Ecuador, Mexico, Peru, Puerto Rico, Uruguay, and Venezuela.Crohn disease (CD) was more frequent in Puerto Rico (71.9%), the Dominican Republic (61.0%), and Peru (53.1%). Ulcerative colitis was more frequent in Colombia (78.6%), Venezuela (78.2%), Mexico (75.5%), Cuba (69.9%), Ecuador (64.1%), and Uruguay (60.9%). The following clinical characteristics were more frequent in the Caribbean: penetrating behavior in CD, steroid dependence, steroid resistance, intolerance to thiopurines, extraintestinal manifestations, surgeries, hospitalizations due to IBD, and family history of IBD. The factors associated with the use of biological therapy were pancolitis in ulcerative colitis, penetrating behavior in CD, steroid resistance and dependence, presence of extraintestinal manifestations, and the need for surgery.This study from Latin America and the Caribbean demonstrated the different epidemiological and clinical characteristics of IBD.

RESUMEN

OBJECTIVE: Inflammatory Bowel Disease has increased in Hispanics. This study estimates its prevalence in Puerto Rico for 2013 and compares it with prior reports. METHODS: The database of commercial and government insurance claims of the Department of Health for 2013 was used. A case was defined as having at least two medical claims of outpatient services or one or more hospitalizations and emergency department visits with an ICD-9 code for Crohn's disease or ulcerative colitis. Cases with codes for both were classified as undetermined inflammatory bowel disease. Prevalence was calculated for inflammatory bowel disease, Crohn's disease, and ulcerative colitis overall and by age, sex, and health insurance. RESULTS: 5,378 persons were classified as having inflammatory bowel disease, for an overall prevalence of 181.54/100,000. Of these, 2,154 had Crohn's disease and 2,689 had ulcerative colitis, with prevalences of 72.71 and 90.77/100,000 respectively. Crohn's disease was more prevalent in males and ulcerative colitis in females. Both types were more prevalent in the government insured population. 719 children had inflammatory bowel disease, for a prevalence of 89.8/100,000. Of these, 480 were classified as Crohn´s disease and 169 as ulcerative colitis. Prevalences for pediatric Crohn's disease and ulcerative colitis were 60.0 and 21.2/100,000 respectively. CONCLUSION: When compared with a report for 2005, the prevalence for inflammatory bowel disease in Puerto Rico for 2013 showed a 4-fold increase overall and a 3-fold increase in children. Inflammatory bowel disease was more prevalent in government-insured as opposed to commercially insured persons, in contrast with previous findings.

RESUMEN

OBJECTIVE: In 2017, the government of Puerto Rico legalized medical cannabis for several conditions including Crohn's disease (CD). There is little information about cannabis use in this population. This study aimed to develop a demographic characterization and evaluate patient perception on cannabis use for Inflammatory Bowel Disease (IBD) at the University of Puerto Rico Center for Inflammatory Bowel Diseases. METHODS: One hundred patients of ages 21 or older with a confirmed diagnosis of IBD were recruited to complete a voluntary anonymous questionnaire. RESULTS: 27% of the surveyed participants reported use of cannabis. Of these, 39% reported moderate knowledge and 53% reported little to no knowledge of medical cannabis. The majority did not discuss cannabis use with their physician (78%), and most saw improvement of their symptoms (68%). CONCLUSION: Cannabis is frequently considered by patients as a treatment option for IBD but most have limited knowledge about its use. The low number of patients that discuss cannabis use with their physician suggests the need for physician awareness of unreported use. It should also lead to the development of strategies for patient orientation regarding the uses, properties, and expectations of cannabis as a therapy.

RESUMEN

Patients with immune conditions and immune-modifying therapies were excluded from the Covid-19 vaccine trials. Studies have shown conflicting response to different vaccines in persons receiving immune suppressors or biologics. The aim of this study is to evaluate humoral and cellular response to Covid-19 vaccines in patients with Inflammatory Bowel Disease (IBD) using biologic and/or immunomodulatory (IMM) therapies. Methods: Participants are adults with IBD receiving biologics or IMM planning to receive a Covid 19 vaccine. Cellular immunity (CD4+ and CD8+ T cell levels) with flow cytometry are measured at baseline and 2 weeks after each vaccine dose. Humoral immunity (antibody titers and neutralizing capacity,VNT%) is analyzed by ELISA at baseline, 2 weeks after each dose, and 6 and 12 months after vaccine. We present the early results of the first 19 subjects. The study is approved by the IRB. Results: 19 subjects (18 in biologics and 1 in IMM) who received 2 doses of the Pfizer-BioNTech vaccine are included. Total IgG antibodies increased 21.13 times after the first dose and 90 times after the second dose. VTN% increased 11.92 times after the first dose and 53.79 times after the second dose. When compared with a healthy control cohort, total IgG antibodies and VTN% were lower in the subjects after the first dose. After the second dose, IgG antibodies increased but remained lower than controls, but VTN% were similar to controls. CD4 and CD8 mean levels had an upward trend after vaccination. Conclusions: Neutralizing capacity response to the vaccine in subjects was similar to a healthy cohort in spite of lower increases in total IgG antibodies. The CD4 and CD8 results observed may support the capacity to mount an effective cellular response in patients on biologics. Larger studies are needed to determine vaccine efficacy in these patients.

RESUMEN

OBJECTIVE: Irritable bowel syndrome (IBS) is characterized by chronic abdominal pain and altered bowel habits. A high prevalence has been reported in medical students around the globe. This study aimed to investigate the prevalence of IBS and associated risk factors in medical students in Puerto Rico (PR). METHODS: A cross sectional study was conducted in a sample of medical students from first to fourth year currently enrolled at the University of PR School of Medicine. Participants completed a self-administered, anonymous questionnaire that contained questions about general socio-demographic data, lifestyle habits, degree of subjective psychological stress and the Rome III criteria: IBS Module. RESULTS: 314 medical students were included for analysis. The mean age was 24.8±3.25; 48.1% were females. The prevalence of IBS was 36.3%. Among the IBS subjects, 78 (24.8%) were classified as IBS mixed. Family history of IBS and psychological stress were significantly associated to IBS (p<0.05), whereas cigarette smoking was found to be protective for IBS (OR = 0.26 + .17, P=.04). CONCLUSION: This is the first study to describe the prevalence of IBS in medical students in PR. A higher prevalence of IBS was found as compared to that reported for medical students in other countries. Additional studies aimed at estimating the impact of IBS on quality of life and academic performance of the medical students are essential.

RESUMEN

Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gut. Genetic association studies have identified the highly variable human leukocyte antigen (HLA) region as the strongest susceptibility locus for IBD and specifically DRB1*01:03 as a determining factor for ulcerative colitis (UC). However, for most of the association signal such as delineation could not be made because of tight structures of linkage disequilibrium within the HLA. The aim of this study was therefore to further characterize the HLA signal using a transethnic approach. We performed a comprehensive fine mapping of single HLA alleles in UC in a cohort of 9272 individuals with African American, East Asian, Puerto Rican, Indian and Iranian descent and 40 691 previously analyzed Caucasians, additionally analyzing whole HLA haplotypes. We computationally characterized the binding of associated HLA alleles to human self-peptides and analyzed the physicochemical properties of the HLA proteins and predicted self-peptidomes. Highlighting alleles of the HLA-DRB1*15 group and their correlated HLA-DQ-DR haplotypes, we not only identified consistent associations (regarding effects directions/magnitudes) across different ethnicities but also identified population-specific signals (regarding differences in allele frequencies). We observed that DRB1*01:03 is mostly present in individuals of Western European descent and hardly present in non-Caucasian individuals. We found peptides predicted to bind to risk HLA alleles to be rich in positively charged amino acids. We conclude that the HLA plays an important role for UC susceptibility across different ethnicities. This research further implicates specific features of peptides that are predicted to bind risk and protective HLA proteins.

RESUMEN

OBJECTIVE: Inflammatory bowel disease (IBD) negatively impacts quality of life-related issues including intimacy, body image, and sexual activity. Sexual dysfunction in patients with IBD is often unrecognized. In this study, we aimed to describe sexual function in Puerto Rican women with IBD. METHODS: We conducted a cross-sectional study of women with IBD at the University of Puerto Rico Center for IBD. Patients were invited to anonymously complete the validated Spanish version of the Female Sexual Function Index (FSFI) questionnaire. On this 36-point scale, a score of 26.55 or less is defined as sexual dysfunction. Data were analyzed by diagnosis, presence of an ostomy, and age, using descriptive statistics, ANOVA, Student's t test, and logistic regression. RESULTS: One hundred women completed the FSFI questionnaire, with subjects having Crohn's disease (CD) outnumbering those having ulcerative colitis (UC) 2:1. The mean sexual function score was 21.92 (95% CI: 20.08-23.76). No statistical difference was observed in total FSFI scores between subjects with CD and UC (p = 0.084) and those with an ostomy (p = 0.891). Sexual function decreased with age (p = 0.001). The domains of excitation, lubrication, orgasm, and satisfaction were the most negatively affected (p<0.05) by increasing age. Multivariate analysis confirmed the effect of age on excitation, lubrication, orgasm, and pain. CONCLUSION: Our study showed sexual dysfunction to be present in this sample of Puerto Rican Hispanic women with IBD. Physicians treating patients with IBD need to be aware of these findings to explore the concerns of individuals with this disease and develop strategies to address those concerns.

RESUMEN

OBJECTIVE: In this study, we assessed the Kidney Donor Risk Index (KDRI) in Puerto Rican deceased kidney donors whose donations took place from 2009 to 2011 and evaluated short-term graft survival in the recipients of those kidneys. The results highlight differences between the distributions of KDRI values in the populations of the 48 contiguous states of the United States, Alaska, and Hawaii and that of Puerto Rico. Additionally, we evaluated the impacts of polyomavirus (BKV) infection and anti-donor HLA antibodies on the recipients. METHODS: Of the 377 kidneys obtained from deceased donors by LifeLink of Puerto Rico from 2009 to 2011, 187 were transplanted in Puerto Rico. Data was collected from the deceased donors of these 187 kidneys for calculating KDRI, as well as from the transplant recipients. KDRI values of the donors were calculated using the same formula as previously reported for the United States; death-censored graft survival, incidence of antibody-mediated rejection, and prevalence of polyoma virus infection (BKV) were examined in the recipients. RESULTS: The mean KDRI value was 1.19. However, the distribution of KDRI values in the Puerto Rican population deviates substantially from that of the United States (not including Puerto Rico). A 1-peak distribution pattern describes Puerto Rican KDRI values. Graft survival for the study period was 89.6%. The prevalence of BKV was 16.9%. Of the patients studied, 6.25% developed overt nephropathy, 46.2% developed de novo post-transplant donor-specific alloantibodies, and 19.5% had pre-existing alloantibodies. CONCLUSION: Our study evidences the role of various characteristics in the distribution of KDRI values in the Puerto Rican population, suggesting that the identification of variables specific to a geographically distinct group may result in better donor categorization for predicting transplant outcomes. In addition, our graft-survival results, despite the elevated rates of BKV and anti-donor antibodies, highlight the increasing need to monitor the presence of antibodies in a prospective and an anticipatory manner to identify and manage patients at risk for antibodymediated rejection.

AIM: To determine serum vitamin D levels and colonic vitamin D receptor (VDR) expression in inflammatory bowel disease (IBD) and non-IBD patients and correlate these with histopathology. METHODS: Puerto Rican IBD (n = 10) and non-IBD (n = 10) patients ≥ 21 years old scheduled for colonoscopy were recruited. Each patient completed a questionnaire and provided a serum sample and a colonic biopsy of normal-appearing mucosa. For IBD patients, an additional biopsy was collected from visually diseased mucosa. Serum vitamin D levels were measured by ultra-performance liquid chromatography and mass spectrometry. Hematoxylin and eosin stained tissue sections from colonic biopsies were classified histologically as normal or colitis (active/inactive), and scored for the degree of inflammation present (0-3, inactive/absent to severe). Tissue sections from colonic biopsies were also stained by immunohistochemistry for VDR, for which representative diagnostic areas were photographed and scored for staining intensity using a 4-point scale. RESULTS: The IBD cohort was significantly younger (40.40 ± 5.27, P < 0.05) than the non-IBD cohort (56.70 ± 1.64) with a higher prevalence of vitamin D deficiency (40% vs 20%, respectively) and insufficiency (70% vs 50%, respectively). Histologic inflammation was significantly higher in visually diseased mucosa from IBD patients (1.95 ± 0.25) than in normal-appearing mucosa from control patients (0.25 ± 0.08, P < 0.01) and from IBD patients (0.65 ± 0.36, P < 0.05) and correlated inversely with VDR expression in visually diseased colonic tissue from IBD patients (r = -0.44, P < 0.05) and from IBD patients with Crohn's disease (r = -0.69, P < 0.05), but not in normal-appearing colonic tissue from control patients or IBD patients. Control and IBD patient serum vitamin D levels correlated positively with VDR expression in normal colon from control and IBD patients (r = 0.38, P < 0.05) and with patient age (r = 0.54, P < 0.01). CONCLUSION: Levels of serum vitamin D correlate positively with colonic VDR expression in visually normal mucosa whereas inflammation correlates negatively with colonic VDR expression in visually diseased mucosa in Puerto Rican patients.

RESUMEN

Women with inflammatory bowel disease (IBD) may be at increased risk of human papilloma virus (HPV) infection and HPV-related malignancies, as many are immunocompromised secondary to the use of immunosuppressant agents. Several studies have addressed the knowledge about cervical cancer risk factors in different populations, particularly HPV infection and its association with cervical malignancies; most of these studies show poor patient knowledge. The purpose of this study is to describe the knowledge of females with IBD about HPV infection and the HPV vaccine. We performed a cross-sectional study in 147 consecutive patients attending the clinics of the University of Puerto Rico Center for IBD from 2009 to 2010. An interviewer-administered questionnaire was used to collect information on demographics, lifestyles, and HPV-related knowledge of participants. Bivariate analysis using the chi-square statistics and Fisher's exact test was used to examine factors associated with HPV awareness. The mean age of participants was 36.6 years (SD = 13.91 years). Three fourth (77 %) of women had awareness of the existence of HPV, and 58 % did know about the existence of HPV vaccines. Among those who had heard about HPV, 79.6 % knew that HPV can cause cervical cancer, and 57.5 % knew that the virus is sexually transmitted. Among those who knew of the vaccine, 75.3 % learned about its existence through the media, while only 15.3 %, through their health-care provider. Only three women within recommended ages (2 %) had been vaccinated against HPV, although 50 % of participants indicated that they would definitely/probably vaccinate against HPV in the future. A significant trend was observed, where more educated women were more likely to have heard of HPV (p for trend = 0.0017). Women who were high school graduates/some college (OR = 6.63, 95 % CI = 1.71-25.66) and those with at least an associate degree (OR = 11.69, 95 % CI = 3.05-45.89) were more likely to be aware of the HPV vaccine than women without a high school degree. Our study documents poor knowledge of HPV and HPV vaccine in this population of IBD patients in Puerto Rico. Although vaccination coverage is low in this population, women are receptive to the possibility of vaccination in the future. Given that this population may be at an increased risk of HPV infection and related morbidities, education and vaccination programs should be promoted among them.

RESUMEN

Since the introduction of liver transplant as treatment for end-stage liver disease, thousands of lives have been saved. To prevent organ rejection, immunosuppression is given chronically and hence, patients are at increased risk for opportunistic infections related to immunosuppression, especially within the first year after the transplant. However, opportunistic infections can occur years after the transplantation. Disseminated nocardiosis is one of these infections, and although the common presentation includes involvement of skin, lungs, and central nervous system. We present an uncommon presentation of nocardiosis in which cholestasis and elevated liver enzymes predominate, mimicking organ rejection and liver disease recurrence. Infectious etiologies, including opportunistic microorganisms, must always be ruled out in patients presenting elevation in liver enzymes and cholestasis after liver transplant as early diagnosis can prevent complications such as re-transplantation and even death.
