Multiple Complications of Crohn's Disease and the Need for Early and Continuous Multidisciplinary Undertaking.

Crohn's disease is an inflammatory disease that typically affects the bowels but can also have many different extraintestinal manifestations. One of those complications is immunoglobulin A nephropathy (IgAN), which is one of the most encountered renal lesions in the setting of Crohn's disease. Another point of focus for Crohn's patients is the risk of cancer, with a higher risk of colorectal cancer but also extraintestinal neoplasia such as hepatobiliary, hematological, and urinary tract neoplasia. We present the case of a young patient suffering from long-term Crohn's disease and subsequent IgAN leading to end-stage kidney disease and hemodialysis. The patient was diagnosed young and had undergone multiple surgeries and different treatments in various countries. He then presented in our center already with advanced chronic renal failure from IgAN that was unknown due to poor multidisciplinary follow-up. Shortly after starting hemodialysis, he developed a large abdominal mass, first thought to result from Crohn's-related fistula. This mass turned out to be a urachal adenocarcinoma, a rare type of bladder cancer with an especially poor prognosis. It is not known whether this type of cancer is associated with either Crohn's disease or IgAN, and no such association has been previously described. The treatment of urachal cancer usually relies on surgery, with the addition of chemotherapy in some cases. Unfortunately for our patient, his case was already so advanced at the moment of diagnosis that he was excluded from curative treatment and quickly passed away thereafter. This case illustrates many important aspects of the rigorous follow-up that is needed for Crohn's patients, with regular check-ups, screening investigations, and the need for multidisciplinary evaluation. Furthermore, it describes the development of a rare type of cancer in the setting of Crohn's disease and IgAN, with no prior established link between these different pathologies.

Evaluation of Transplant Suitability in a Patient with Previous Colorectal Cancer and Subsequent Radiation Cystitis: Insights from a Complicated Case.

Assessing transplant suitability can be a meticulous process, involving multiple investigations and various specialties. This process is well described in the latest KDIGO guidelines. We recently asked ourselves if those guidelines are still relevant to current clinical practice given the rapid evolution of modern medicine, especially in the field of oncology. We present the complicated case of a 60-year-old woman with ESKD (end-stage kidney disease) and a prior history of cancer, with secondary urological complications, to illustrate different interesting considerations for KT (kidney transplant). Our patient was diagnosed with rectal cancer at the age of 46, for which she was treated with surgery and radiotherapy before developing chronic radiation cystitis. This was followed by repeated urinary tract infections and secondary nephrolithiasis, ultimately leading to severe bilateral hydronephrosis and obstructive ESKD. We know that the type of cancer and its characteristics should be evaluated in detail, and we should offer patient-tailored recommendations after a multidisciplinary evaluation. In our case, the prior rectal cancer is not to be feared because curative treatment has been achieved and the patient has been cancer-free for 14 years, knowing that this type of cancer is not at high risk of recurrence after transplantation. The frail urological anatomy, however, represents a bigger challenge. Not only does it complicate the technical feasibility of KT but it also increases the risk of complications and graft failure. It is difficult to clearly determine KT possibility when considering it in such patients. What is clear on the other hand is that such a decision should be taken considering the choice of the patient and the involved physicians. We should also consider the potential benefits and risks of KT in order to make an informed decision.

Native Mitral Valve Endocarditis Caused by a Non-HACEK Gram-Negative Pathogen in a Hemodialysis Patient.

Infective endocarditis (IE) due to non-HACEK (species other than Hemophilus, Aggregatibacter, Cardiobacterium, Eikenella, Kingella) bacteremia accounts for less than 2% of all IE cases but is proven to be associated with higher mortality, even more so in hemodialysis (HD) patients. Few data are available in the literature concerning non-HACEK Gram-negative (GN) IE in this immunocompromised population with multiple comorbidities. We report the atypical clinical presentation of an elderly HD patient diagnosed with a non-HACEK GN IE, namely E. coli, successfully treated with intravenous (IV) antibiotics. The objective of this case study and related literature was to highlight the limited applicability of the modified Duke criteria in the HD population, as well as the frailty of HD patients that increases their susceptibility to IE due to unexpected microorganisms that could have fatal consequences. The need for a multidisciplinary approach of an IE in HD patients is therefore imperative.

COVID-19 impact on an oncologic emergency department visits: observational study.

OBJECTIVE: This study aimed at evaluating the impact of COVID-19 on emergency department (ED) visits in a tertiary cancer centre and providing information on the features of the unplanned events during the first wave of COVID-19 pandemic. METHODS: This retrospective observational study based on data from ED reports was divided into three periods of 2 months each around the first lockdown announcement of 17 March 2020: pre-lockdown, lockdown and post-lockdown. RESULTS: A total of 903 ED visits were included in the analyses. The mean (±SD) daily number of ED visits did not change during the lockdown period (14.6±5.5) when compared with the periods before (13.6±4.5) and after lockdown (13.7±4.4) (p=0.78). The proportion of ED visits for fever and respiratory disorders increased significantly to 29.5% and 28.5%, respectively (p<0.01) during lockdown. Pain, the third most frequent motive, remained stable with 18.2% (p=0.83) throughout the three periods. Symptom severity also showed no significant differences in the three periods (p=0.31). CONCLUSION: Our study shows that ED visits during the first wave of the COVID-19 pandemic remained stable for our patients regardless of the symptom's severity. The fear of an in-hospital viral contamination appears weaker than the need for pain management or for the treatment of cancer-related complications. This study highlights the positive impact of cancer ED in the first-line treatment and supportive care of patients with cancer.

Undetected Iatrogenic Drug-Induced Complications in a Hemodialyzed Anuric Patient: A Case Report and Review of the Literature.

Anuric hemodialyzed end-stage renal disease patients are prone to multiple complications and comorbidities and are therefore often treated with various medications. Adverse drug reactions and risk factors leading to them can be difficult to discern in such polymedicated patients. Most problems regarding low phosphate levels are frequently underdiagnosed in clinical practice and sometimes overlooked in these regularly hyperphosphatemic patients. Hemodialysis vascular accesses are frequently subject to infections and therefore require adapted antibiotic treatments. We report a case of an occult severe multifactorial hypophosphatemia in an anuric hemodialyzed patient with multiple comorbidities who required two hospitalizations for encephalopathy, seizures, and cardiac failure. Retrospective analysis of the medical record revealed several underlying causes of hypophosphatemia, as well as undetected risk factors for adverse drug reactions related to cephalosporins. A global approach to these concerns in routine clinical practice would raise awareness of often disregarded issues related to hypophosphatemia and drug prescription in these patients.

Severe Bullous Pemphigoid Onset after Jugular Catheter Placement in a Patient on Hemodialysis.

Pruritus is highly prevalent in the dialysis population. Its etiology however remains often unclear with uremic pruritus primarily suspected unless compelling evidence of another cause. Although bullous pemphigoid (BP) is considered idiopathic, there are growing data in the literature on BP provoked by different factors, such as medications or surgical procedures. These secondary dermatoses are described as rather mild conditions and more frequent in the elderly Caucasian. We herein describe a newly dialyzed African man of 76 years old, treated by a sulfonylurea such as an antidiabetic drug, who developed a severe BP after jugular catheter placement.

Iatrogenic Infective Endocarditis in Hemodialysis Patients: A Case Report and Review of the Literature.

Foreign bodies such as implanted cardiac devices are susceptible to infections and may be involved in infective endocarditis. Exposure to pathogens, by frequent use of intravascular accesses for hemodialysis (i.e., catheters or fistulas), combined with high rates of degenerative heart valve diseases in hemodialysis patients, both favor the development of infective endocarditis in this population. The mitral and aortic valves are predominantly implicated in endocardial infections. The involvement of both mitral and tricuspid valves is rare in the general population but can occur in hemodialysis patients with implanted cardiac devices. Infective endocarditis is associated with high morbidity and mortality rates among hemodialysis patients, mostly because of the complications of septic emboli. Prevention, prophylaxis, and early diagnosis of endocarditis can be lifesaving in this fragile population. We report a case of right and left heart methicillin-sensitive Staphylococcus aureus endocarditis with cerebral septic emboli in an elderly hemodialysis patient carrier of an arteriovenous fistula and an ipsilateral nonleadless pacemaker.

Factors associated with SARS-CoV-2 infection and outcome in patients with solid tumors or hematological malignancies: a single-center study.

BACKGROUND: Immunocompromised cancer patients are presumed to be at high risk of developing COVID-19 infection. Predisposing factors to contracting COVID-19 and to severe outcomes have been described in registries but were not compared between solid tumors and hematological malignancies. METHOD: This retrospective single oncologic center study included adults with solid tumors or hematological malignancies referred to testing by naso-pharyngeal swab for a SARS-CoV-2 RT-PCR from March 10 to May 18, 2020. RESULTS: A total of 212 patients were included in the study. Forty-five (21%) were tested positive with SARS-CoV-2. The univariate analysis with positive SARS-CoV-2 PCR as a dependent variable reveals significant odds ratios (ORs) for age-with a mean of 62.5 years-(OR: 1.05, 95% CI: 1.02-1.08), performance status ≥2 (OR: 2.38, 95% CI: 1.22-4.70), inpatient status (OR: 2.36, 95%CI: 1.11-4.91), and hematological malignancies (OR: 2.48, 95% CI: 1.23-4.96). In contrast, OR for solid tumors reveals a negative association (OR: 0.40, 95% CI: 0.20-0.81). When integrating severe outcome (ICU admission or COVID-19-related death) as a dependent variable, the univariate logistic regression model shows significant ORs for pre-existing lymphopenia (OR: 4.0, 95% CI: 1.17-15.04), hematological malignancies (OR: 3.73, 95% CI: 1.09-13.80), and a negative association for solid tumors (OR: 0.27; 95% CI: 0.07-0.92). CONCLUSION: In patients referred for SARS-CoV-2 testing, hematological malignancies were associated with a higher risk of COVID-19 infection and severe outcomes. Other factors were age and inpatient status.
