Rare case of postherpetic abdominal pseudohernia in a patient on peritoneal dialysis.

Patients affected by chronic kidney disease, especially those requiring maintenance dialysis therapy, are particularly susceptible to infections, including reactivation of herpes zoster and are also at increased risk of herpes zoster complications. Postherpetic abdominal pseudohernia is a rare sequela of the infection, caused by motor neuropathy with muscle paresis, that manifests as an abdominal protrusion. In patients receiving peritoneal dialysis who may often present slight abdominal distension, the diagnosis of this complication may be challenging. We present a case of this rare neurological complication in a patient on peritoneal dialysis and discuss its etiology and management. To the best of our knowledge, this is the first report of postherpetic abdominal pseudohernia in a patient receiving kidney replacement therapy.

Identification of palliative care needs and prognostic factors of survival in tailoring appropriate interventions in advanced oncological, renal and pulmonary diseases: a prospective observational protocol.

INTRODUCTION: It is estimated that of those who die in high-income countries, 69%-82% would benefit from palliative care with a high prevalence of advanced chronic conditions and limited life prognosis. A positive response to these challenges would consist of integrating the palliative approach into all healthcare settings, for patients with all types of advanced medical conditions, although poor clinician awareness and the difficulty of applying criteria to identify patients in need still pose significant barriers. The aim of this project is to investigate whether the combined use of the NECPAL CCOMS-ICO and Palliative Prognostic (PaP) Score tools offers valuable screening methods to identify patients suffering from advanced chronic disease with limited life prognosis and likely to need palliative care, such as cancer, chronic renal or chronic respiratory failure. METHODS AND ANALYSIS: This multicentre prospective observational study includes three patient populations: 100 patients with cancer, 50 patients with chronic renal failure and 50 patients with chronic pulmonary failure. All patients will be treated and monitored according to local clinical practice, with no additional procedures/patient visits compared with routine clinical practice. The following data will be collected for each patient: demographic variables, NECPAL CCOMS-ICO questionnaire, PaP Score evaluation, Palliative Performance Scale, Edmonton Symptom Assessment System, Eastern Cooperative Oncology Group Performance Status and data concerning the underlying disease, in order to verify the correlation of the two tools (PaP and NECPAL CCOMS-ICO) with patient status and statistical analysis. ETHICS AND DISSEMINATION: The study was approved by local ethics committees and written informed consent was obtained from the patient. Findings will be disseminated through typical academic routes including poster/paper presentations at national and international conferences and academic institutes, and through publication in peer-reviewed journals.

The link between homocysteine, folic acid and vitamin B12 in chronic kidney disease.

Patients with chronic kidney disease or end-stage renal disease experience tremendous cardiovascular risk. Cardiovascular events are the leading causes of death in these patient populations, thus the interest in non-traditional risk factors such as hyperhomocysteinemia, folic acid and vitamin B12 metabolism is growing. Hyperhomocysteinemia is commonly found in CKD patients because of impaired renal metabolism and reduced renal excretion. Folic acid, the synthetic form of vitamin B9, is critical in the conversion of homocysteine to methionine like vitamin B12. Folic acid has also been shown to improve endothelial function without lowering homocysteine, suggesting an alternative explanation for the effect of folic acid on endothelial function. Whether hyperhomocysteinemia represents a reliable marker of cardiovascular risk and cardiovascular mortality or a therapeutic target in this population remains unclear. However, it is reasonable to consider folic acid with or without methylcobalamin supplementation as appropriate adjunctive therapy in patients with CKD. The purpose of this review is to summarize the characteristics of homocysteine, folic acid, and vitamin B12 metabolism, the mechanism of vascular damage, and the outcome of vitamin supplementation on hyperhomocysteinemia in patients with CKD, ESRD, dialysis treatment, and in kidney transplant recipients.

COVID-19 pandemic era: is it time to promote home dialysis and peritoneal dialysis?

The novel coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was declared a pandemic in March 2020 by the World Health Organization. Older individuals and patients with comorbid conditions such as hypertension, heart disease, diabetes, lung disease, chronic kidney disease (CKD) and immunologic diseases are at higher risk of contracting this severe infection. In particular, patients with advanced CKD constitute a vulnerable population and a challenge in the prevention and control of the disease. Home-based renal replacement therapies offer an opportunity to manage patients remotely, thus reducing the likelihood of infection due to direct human interaction. Patients are seen less frequently, limiting the close interaction between patients and healthcare workers who may contract and spread the disease. However, while home dialysis is a reasonable choice at this time due to the advantage of isolation of patients, measures must be assured to implement the program. Despite its logistical benefits, outpatient haemodialysis also presents certain challenges during times of crises such as the coronavirus disease 2019 (COVID-19) pandemic and potentially future ones.

Lung Ultrasound in Hemodialysis: A Card to be Played?

The end-stage renal disease is characterized by a profound impairment in the regulation of body fluid distribution, and volume assessment in hemodialysis is one of the challenging goals for the nephrologist. To determine a state of euvolemia, different validated techniques have been employed and among them lung ultrasonography (LUS) has recently attracted growing attention on account of its capacity to estimate accurately extra vascular lung water and to detect lung edema even in its early asymptomatic stage, that is, hidden lung congestion.With its noninvasiveness, freedom from radiation, the ease of use, acceptable intra/inter-operator reproducibility and availability of portable ultrasound devices, LUS can be considered one of the most interesting "cards to play" for the volume assessment in patients on hemodialysis.
