Esophagogastroduodenal Findings in Patients with Intraductal Papillary Mucinous Neoplasms

The association between intraductal papillary mucinous neoplasms (IPMNs) and extra-pancreatic malignancies is controversial. This cross-sectional study compared esophagogastroduodenal findings in 340 IPMN patients to those of age- and gender-matched controls without known IPMNs who underwent esophagogastroduodenoscopies (EGDs) for similar clinical reasons. The presence of gastric and esophageal cancer, Barrett's esophagus, neuroendocrine tumors (NETs), gastrointestinal stromal tumors (GISTs), gastric adenomas, and ampullary tumors was assessed. The results showed that 4/340 (1.2%) of the IPMN patients had gastric cancer and 1/340 (0.3%) had esophageal cancer. The matched control group had a similar incidence of gastric cancer (5/340) (1.5%), with no esophageal cancer cases (p > 0.999). The overall incidence of other esophagogastroduodenal conditions did not significantly differ between the IPMN patients and the controls. However, the incidence of gastric cancer in the IPMN patients was higher than expected based on national cancer registry data (standardized incidence ratio of 31.39; p < 0.001; CI 8.38-78.76). In conclusion, IPMN patients have a significantly higher incidence of gastric cancer compared to the general population. However, the incidence of esophagogastroduodenal findings, including gastric and esophageal cancer, is similar between IPMN patients and those who undergo an EGD for similar clinical indications. Further research is needed to determine optimal surveillance strategies for IPMN patients regarding their risk of developing gastric cancer.

Nonalcoholic Fatty Liver Disease before Kidney Transplantation Correlates with New Onset Diabetes and Poor Metabolic Outcomes

INTRODUCTION

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality after kidney transplantation. Metabolic syndrome is common in renal transplant recipients and is associated with increased CVD risk in those patients. Nonalcoholic fatty liver disease (NAFLD) is considered to be the hepatic manifestation of a multi-system disorder, including CVD and metabolic syndrome. The data about prevalence of NAFLD before kidney transplantation and its consequences following transplantation are scarce.

METHODS

A retrospective study of metabolic parameters and sonographic evidence of NAFLD, and an analysis of its metabolic outcomes, was performed in 341 consecutive kidney transplant recipients.

RESULTS

One-hundred twenty-four (36.4%) kidney recipients had NAFLD before transplantation. The risk of NAFLD before kidney transplantation was independently and significantly related to diabetes (OR = 1.8), male gender (OR = 1.4), older age (every year of age increased the risk by 4%), higher BMI (every increase of 1 kg/m2 increased the risk by 15%), and higher triglycerides level. Mean levels of liver enzymes were similar in patients with and without NAFLD. Recipients with NAFLD before transplantation had a higher prevalence of new onset diabetes, even after adjustment to covariables. In addition, they had a higher increase in liver enzymes, triglycerides, and FIB-4 score, as an indication of liver fibrosis, after transplantation. Furthermore, NAFLD pre-transplantation was independently associated with cardiovascular mortality (HR = 4.4) following kidney transplantation.

CONCLUSIONS

Sonographic evidence of NAFLD before kidney transplantation is associated with significant metabolic outcomes including de novo diabetes and cardiovascular mortality following transplantation and should be included as part of the assessment of kidney transplant candidate.

Ustekinumab during pregnancy in patients with inflammatory bowel disease: a prospective multicentre cohort study

BACKGROUND

Women with inflammatory bowel diseases (IBD) often receive biologics to maintain remission during pregnancy.

AIMS

To assess maternal and neonatal outcomes in patients with IBD treated with ustekinumab (UST) during pregnancy METHODS: In a multicentre, prospective cohort study, we recruited women with IBD treated with UST during pregnancy between 2019 and 2021. Outcomes were compared among patients treated with UST, anti-tumour necrosis factor α, (anti-TNF) and non-UST, non-anti-TNF therapies. UST-treated patients were matched 1:2 to controls according to age, body mass index and parity. Newborns were followed up to 12 months.

RESULTS

We recruited 129 pregnant patients: UST 27; anti-TNF 52; non-UST, non-anti-TNF 50 (thiopurine or mesalazine 30, no therapy 20); Crohn's disease 25 (96.9%). Overall, pregnancy, neonatal and newborn outcomes were satisfactory, with no significant differences among patients treated with UST, anti-TNF and non-UST non-anti-TNF agents for obstetrical maternal complications [UST 3 (11.5%), anti TNF 12 (23.1%), non UST, non-anti-TNF 4 (8.2%), p = 0.095], pre-term delivery [1 (4.3%), 9 (18.4%), 4 (5.7%), p = 0.133], low birth weight [1 (4.2%), 5 (10.2%), 4 (8.3%), p = 0.679], or first year newborn hospitalisation [2 (9.1%), 4 (8.2%), 3 (6.1%), p = 0.885].

CONCLUSION

Pregnant patients with IBD treated with UST demonstrated favourable pregnancy and neonatal outcomes that were comparable with those in patients treated with anti-TNF or other therapy. Data are reassuring for patients with IBD and their physicians when considering UST during pregnancy.

Presence of Sarcopenia before Kidney Transplantation Is Associated with Poor Outcomes

Introduction

Kidney transplantation is the treatment of choice for patients with renal failure. It is crucial to select which patients may benefit from renal transplantation and which are at high risk for post-transplant complications. Sarcopenia is associated with poor outcome in various conditions, including in chronic kidney disease patients. The gold standard for measuring sarcopenia is computed tomography (CT) imaging to estimate muscle mass and quality since it is objective, reproducible, and reflects the overall health condition. The data regarding those measurements among kidney transplant recipients are limited, therefore we aimed to describe it in patients before kidney transplantation, assess the parameters associated with sarcopenia, and evaluate the clinical significance of those markers on outcomes following transplantation.

Methods

We retrospectively analyzed 183 kidney transplant recipients who had a CT scan 90 days prior to transplant. Sarcopenia was assessed by measuring the cross-sectional area (CSA) and mean muscle density of the psoas muscle at the third and fourth lumbar vertebrae levels and paravertebral muscles at the 12th thoracic vertebra level.

Results

There was a strong linear correlation between muscle size measured as CSA of the psoas muscle at the L3 and L4 vertebral body level and the CSA of the paravertebral muscles at the D12 vertebra level, and a moderate correlation to muscle density at those levels. Age was independently associated with risk of sarcopenia, defined as psoas CSA in the lowest tertile, with every year of age increasing the risk by 5%. CSA at the L3 level had a significant independent association with post kidney transplantation mortality, with an adjusted hazard ratio of 0.86 per cm². There was a significantly longer hospitalization period postoperation in kidney recipients in the lower tertile of psoas CSA and density.

Conclusions

Sarcopenia as measured by psoas CSA is associated with poor short- and long-term outcomes following kidney transplantation and should be included as part of the assessment of kidney transplantation candidates.

Proton pump inhibitors long term use-trends and patterns over 15 years of a large health maintenance organization

BACKGROUND

Proton pump inhibitors (PPI) are used for a variety of indications. Despite reported associations with undesirable effects, their long-term use is on the rise, while appropriate indications, dose, and treatment duration may deviate from guideline recommendations.

OBJECTIVES

Primary to examine the annual patterns of PPI use. Secondary- to assess indications for initiating PPI treatment, long-term use, and factors associated with long-term use in a large Israeli health maintenance organization.

METHODS

A historical cohort study of 528 420 eligible PPI users during 2000-2015, analyzed PPI use using defined daily doses and the proportion of patients covered method. Data on indications for treatment initiation, clinical and socio-demographic parameters were captured as well. A multivariable logistic-regression model was used to identify factors associated with long-term use of PPI.

RESULTS

The annual incidence rates of patients initiating PPI treatment were relatively constant, ranging between 2.4% and 3.1% of the adult population, with a monotonic increase in annual consumption and prevalence (reaching 12.7% in 2015). Reflux, functional symptoms, and Helicobacter pylori eradication were the most common indications for initiating PPI therapy. However, 27% of patients had no recorded indication for treatment. Fifteen percent of patients used PPI for over 6 months, especially in older age groups.

CONCLUSIONS

Utilization of PPI increases steadily, mainly due to chronic use. Prolonged consumption is associated with specific clinical indications and older age. Health organizations should encourage awareness of appropriate use among physicians, specifically in the elderly, patients with reflux, and those with functional disorders.

Cutaneous Malignancies After Kidney and Simultaneous Pancreas-Kidney Transplantations

BACKGROUND

Organ transplant recipients are at increased risk of nonmelanotic skin cancers (NMSC). Scarce data exist regarding secondary malignancies developing post-simultaneous pancreas-kidney (SPK) transplantations. Our aim was to assess long-term risk of skin cancers among kidney alone (KA) and SPK transplantation recipients.

METHODS

In this study, 521 patients who underwent KA or SPK transplantation at our medical center were observed up by dedicated nephrologists and dermatologists. SPK transplantation recipients were matched with a control group of KA transplantation recipients based on demographic and clinical data. A multivariate analysis was performed to find independent cancer risk factors.

RESULTS

Patients who developed skin cancer were generally older, had a fair skin type, and had a higher incidence of NMSC before transplantation. Older age and fair skin type were independent risk factors on multivariate analysis. SPK transplantation in itself was not an independent risk factor. Cancer recurrence was associated with older age and male sex. Darker skin type and lowered immunosuppressive burden were protective.

CONCLUSION

In contrast to previous studies, the use of antithymocytic agents or SPK transplantation were not independently associated with increased skin cancer risk in this multivariate analysis. These findings emphasize the complex interplay between posttransplantation NMSC and various clinical and epidemiologic risk parameters.

Reduction in incidence of invasive fungal infection in patients receiving allogeneic stem cell transplantation using combined diagnostic-driven approach and itraconazole oral solution

Invasive fungal infections are an important cause of morbidity and mortality after allogeneic haematopoietic stem cell transplantation. We evaluated, in our allogeneic stem cell transplant patients, the effect on the incidence of invasive fungal infection during neutropenia of a strategy combining a diagnostic-driven approach with chemoprophylaxis during higher risk periods of graft vs. host disease and prolonged neutropenia, using itraconazole oral solution with parenteral voriconazole bridging. One hundred and thirty patients admitted for allogeneic stem cell transplantation within two predefined 20 month periods were included in the study. Data for all patients were collected prospectively. Implementation of the protocol resulted in the administration of more prophylactic antifungals to more patients. Following implementation, there was a non-significant decrease in the overall number of invasive fungal infections (IFI) [11 of 65 patients (17.2%) vs. 4 of 65 patients (6.2%, P = 0.051)], as well as in the occurrence of invasive mould infections [8 of 65 patients (12.5%) vs. 2 of 65 patients (3.1%, P = 0.054)]. Survival rates at three and 6 months were not significantly affected. A combined diagnostic-driven approach and antifungal prophylaxis with oral itraconazole and an intravenous voriconazole bridging protocol, was associated with a reduced, albeit non-statistically significant, number of IFI in our medical centre.
