Micro-albuminuria and glomerular hyperfiltration are primary indicators of renal dysfunctions in Sickle Cell Disease (SCD), with more severe manifestations previously associated with variants in APOL1 and HMOX1 among African Americans. We have investigated 413 SCD patients from Cameroon. Anthropometric variables, haematological indices, crude albuminuria, albumin-to-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR) were measured. Patients were genotyped for 3·7 kb alpha-globin gene (HBA1/HBA2) deletion, and for variants in APOL1 (G1/G2; rs60910145, rs73885319, rs71785313) and HMOX1 (rs3074372, rs743811)...

BACKGROUND: Cisplatin is a high-potency anticancer agent; however, it causes significant adverse drug reactions (ADRs). Potential pharmacokinetic markers must be studied to predict or prevent cisplatin-induced ADRs and achieve better prognosis. This study was designed to investigate the relationship between ADRs and kinetics of cisplatin excretion in the urine of patients undergoing high-dose cisplatin chemotherapy and radiotherapy for head and neck cancer. METHODS: Outpatients with head and neck cancer received a first cycle of high-dose cisplatin chemotherapy (80-100 mg/m(2)) concurrent to radiotherapy...

BACKGROUND: Uveal melanoma is a rare tumour with no established treatments once metastases develop. Although a variety of immune-based therapies have shown efficacy in metastatic cutaneous melanoma, their use in ocular variants has been disappointing. Recently, adoptive T-cell therapy has shown salvage responses in multiple refractory solid tumours. Thus, we sought to determine if adoptive transfer of autologous tumour-infiltrating lymphocytes (TILs) could mediate regression of metastatic uveal melanoma...

The DHAP regimen (high-dose cytarabine in combination with dexamethasone and cisplatin) with or without rituximab (DHAP+/-R) is one of the most common regimens in daily practice. It is considered the standard treatment for relapse or refractory Hodgkin's and non-Hodgkin's lymphoma (NHL). Cisplatin nephrotoxicity is a major concern, and other platinum compounds are being tried. We performed a monocentric retrospective analysis to evaluate the use of carboplatin, so-called DHAC+/-R regimen. The purpose was to assess the toxicity of the DHAC+/-R regimen in real-life...

BACKGROUND: Although the obesity paradox may vary depending upon clinical background factors such as age, gender, aetiology of heart failure and comorbidities, the reasons underlying the heterogeneous impact of body mass index (BMI) on in-hospital cardiac mortality under various conditions in patients with acute heart failure syndromes (AHFSs) remain unclear. METHODS: Among 4617 hospitalised patients with AHFSs enrolled in the Acute Decompensated Heart Failure Syndromes (ATTEND) registry, the patient characteristics and in-hospital cardiac mortality rates in those with low BMI (BMI <25 kg/m(2), n = 3263) were compared to those with high BMI (BMI ⩾25 kg/m(2), n = 1354)...

CASE REPORT: The case is presented of a young man with an atypical haemolytic-uraemic syndrome (aHUS), complicated with bilateral serous retinal detachment, cotton wool spots, and a branch artery occlusion. Treatment with plasmapheresis, haemodialysis and systemic eculizumab led to the blood and urine parameters returning to normal, as well as resolution of the retinal anomalies. Genetic analysis show both mutations in complement factor H and C3. DISCUSSION: Haemolytic-uraemic syndrome (HUS) is a thrombotic microangiopathy characterised by microangiopathic haemolytic anaemia, thrombocytopenia, and acute renal failure...

Background.: Complement dysregulation occurs in thrombotic microangiopathies (TMAs) other than primary atypical haemolytic uraemic syndrome (aHUS). A few of these patients have been reported previously to be successfully treated with eculizumab. Methods.: We identified 29 patients with so-called secondary aHUS who had received eculizumab at 11 Spanish nephrology centres. Primary outcome was TMA resolution, defined by a normalization of platelet count (>150 × 10 9 /L) and haemoglobin, disappearance of all the markers of microangiopathic haemolytic anaemia (MAHA), and improvement of renal function, with a ≥25% reduction of serum creatinine from the onset of eculizumab administration...

Background Phenylhydrazine (PHE) in experimental animal models has been widely reported to cause haemolytic anaemia, via the induction of oxidative stress and thus causing deleterious cardiovascular complications. Hence, this study was designed to evaluate the possible modulatory role of melatonin (MLT) or vitamin C when co-administered with PHE. Methods Anaemia was established with PHE administration. MLT or vitamin C was co-administered with PHE. Haematological parameters, markers of oxidative stress, enzymic and non-enzymic antioxidants, blood pressure and electrocardiograms were assessed...

OBJECTIVE: Length of stay (LOS) is a major driver of inpatient care costs. To date, few studies have investigated risk factors associated with increased LOS in patients with adult congenital heart disease (ACHD). In the present work, we sought to address this knowledge gap. METHODS: We conducted an analysis of the State Inpatient Databases from Arkansas, California, Florida, Hawaii, Nebraska and New York. We analysed data on admissions in patients with ACHD and constructed a series of hierarchical regression models to identify the clinical factors having the greatest effects on LOS...

AIM: Glomerular hyperfiltration is an early marker of sickle cell nephropathy and can lead to microalbuminuria and renal failure. Our aim was to identify the associated risk factors, as these could be of preventative importance. METHODS: We recruited 150 children with sickle cell anaemia (SCA), aged two to 18 years and living in Kinshasa, the Democratic Republic of Congo. Hyperfiltration and microalbuminuria were defined as an estimated glomerular filtration rate of less than 140 mL/min/1...

Porphyria cutanea tarda (PCT) is a rare disease, with a strong association with hepatitis C virus. PCT is particularly problematic in end-stage renal disease patients as they have no renal excretion of porphyrins and these are poorly dialyzed. Also, conventional treatment of PCT is compromised in these patients as hydroxychloroquine is contraindicated, phlebotomies with the stipulated frequency are poorly tolerated in already anaemia-prone patients, and iron-chelating agents are less efficient in removing iron and contribute to worsening anaemia...

INTRODUCTION: For late-life neurocognitive disorders, as for other late-life chronic diseases, much recent interest has focused on the possible relevance of Developmental Origins of Health and Disease (DOHaD). Programming by undernutrition in utero, followed by overnutrition in adult life may lead to an increased risk, possibly mediated through cardiovascular and metabolic pathways. This study will specifically examine, if lower birth weight is associated with poorer cognitive functioning in late life in a south Indian population...

Cancer patients frequently present with anaemia that may result from the direct or indirect effects of the tumor or its treatment. Anaemia is an independent adverse prognostic factor that exerts negative influence on quality of life and survival of cancer patients. Anaemia in malignant disorders often arises from an interplay of multiple aetiological and pathophysiologic mechanisms. Understanding these mechanisms will help the oncologist identify and treat specific causes of the anaemia thereby minimizing the use of blood transfusion, which is associated with many adverse effects...

Haemolytic uraemic syndrome is a rare condition with an overall incidence of one to two cases in a population of 100 000 and approximately 10% of these cases are classified as atypical. Atypical haemolytic uraemic syndrome (aHUS) is a thrombotic microangiopathy (TMA) characterized by microangiopathic haemolytic anaemia (MAHA), thrombocytopenia and acute kidney injury. aHUS can be genetic, acquired or idiopathic (negative genetic screening and no environmental triggers). We describe a case of aHUS triggered by monoclonal gammopathy of renal significance (MGRS) successfully treated with plasmapheresis and a bortezomib-based chemotherapy regimen, resulting in marked improvement in renal function and other markers of haemolysis...
