OBJECTIVE The relationship between serum creatinine and calcium (Ca) was investigated in hematopoietic stem cell transplantation (HSCT) patients treated with foscarnet. MATERIALS AND METHODS A retrospective study was performed to investigate the development of foscarnet-induced renal dysfunction in patients who received HSCT from April 2010 to November 2018 at the Kindai University Nara Hospital. A total of 80 patients were identified from the medical records, and 42 patients who met the inclusion criteria were enrolled in this study. Renal dysfunction was classified according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria. RESULTS A significant inverse relationship was observed between serum creatinine and Ca levels (r = -0.372; p less then 0.0001; y = -0.537x + 9.268). A separate analysis divided into renal dysfunction and non-renal dysfunction groups showed that there was a significant relationship between serum creatinine and Ca levels in the renal dysfunction group (r = -0.531; p less then 0.0001; y = -0.617x + 9.239) but not in the non-renal dysfunction group (r = -0.011; p = 0.561; y = -0.023x + 8.934). The optimal cutoff for the minimum Ca level was calculated to be 8.1 mg/mL. CONCLUSION A significant inverse relationship was observed between serum creatinine and Ca levels in HSCT patients with foscarnet-induced renal dysfunction. Foscarnet-induced renal dysfunction should be noted if Ca levels fall below 8.1 mg/dL. Monitoring Ca levels may be useful for detecting renal dysfunction at early stages in patients treated with foscarnet.
.OBJECTIVE This work aims to evaluate the therapeutic survey of adverse events during antiviral treatment of hepatitis in the three major University Hospitals in Abidjan. MATERIALS AND METHODS A retrospective cross-sectional descriptive study of 203 patients from August 1, 2015, to July 31, 2018, enumerated adverse events during antiviral treatments, drugs used for their management, and their clinical or biological impact. RESULTS The following was seen hematological disorders during treatment with pegylated interferon α-2a (88.61%) and ribavirin (77.55%), pain syndrome when using pegylated interferon α-2a (90.5%), and digestive disorders while taking sofosbuvir (60.71%) and daclatasvir (66.67%). Hematological disorders were managed with filgrastim for neutropenia and oral iron or blood transfusion for anemia and/or thrombocytopenia. Pain syndrome was treated with paracetamol. As for digestive disorders, they were most often managed with activated charcoal. CONCLUSION Correction of the adverse events was made either using causal treatment or using symptomatic drugs. However, some drugs, in particular hematopoietic factors, have been less used due to their costs.
.AIM Hypertension is a complex condition, and it is difficult to know whether inflammation is a cause or an effect. Information on the association between MRP-8/14 (myeloid-related protein) and hypertension is limited. In this study, we aimed to examine the relationship of MRP-8/14 with carotid intima-media thickness (CIMT) and albuminuria in hypertensive patients and to investigate whether early assay of MRP-8/14 levels could be helpful in assessment of renal damage and carotid atherosclerosis among hypertensive patients. MATERIALS AND METHODS 61 hypertensive patients and 40 age-, gender-, and body mass index-matched controls were included into the study. Blood samples including fasting blood glucose, total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total protein, albumin, urea creatinine, uric acid, sedimentation, C-reactive protein (CRP), and MRP-8/14 were collected. 24-hour urine albumin excretion and CIMT measurements were also obtained. RESULTS All inflammatory variables including uric acid, CRP, sedimentation, MRP-8/14, and CIMT were statistically higher in patients with hypertension than in controls. MRP-8/14 was significantly higher in hypertensive patients with macroalbuminuria than in controls (339.3 (IQR (215.2 - 661.7)) ng/mL vs. 204.9 (IQR (140.1 - 339.3)) -ng/mL, p = 0.005, respectively). The levels of CIMT were the highest in macroalbuminuric hypertensive patients (controls vs. normoalbuminuria, microalbuminuria, macroalbuminuria groups, 0.57 (0.53 - 0.67) mm vs. 0.84 (0.76 - 0.89) mm, p = 0.000; 0.57 (0.53 - 0.67) mm vs. 0.87 (0.67 - 0.93) mm, p = 0.000; 0.57 (0.53 - 0.67) mm vs. 0.92 (0.85 - 0.97) mm, p = 0.000, respectively). CONCLUSION Plasma MRP-8/14 levels were elevated in hypertensive patients with macroalbuminuria, however, it could not serve as an early marker to determine renal damage and carotid atherosclerosis in patients with hypertension.
.BACKGROUND Incident acute kidney injury (AKI) in critically ill patients with acute on chronic liver failure (ACLF) is associated with poor prognosis. The role of continuous renal replacement therapy (CRRT) is not well established for patients with ACLF and AKI. MATERIALS AND METHODS We conducted a retrospective cohort study to examine clinical outcomes in 66 patients with ACLF and AKI requiring CRRT. RESULTS All-cause hospital mortality was 89.4%. Five (7.6%) patients were listed for liver transplantation, of whom 1 (1.5%) was eventually subjected to transplantation. Etiology of AKI included type 1 hepatorenal syndrome (HRS) with or without some degree of acute tubular necrosis (ATN) in 20 (30.3%) patients, and primarily ATN in 46 (69.7%) patients. When evaluated at the time of CRRT initiation, Child-Pugh-Turcotte (CPT) and Model for End-stage Liver Disease (MELD) (area under the receiver operating characteristics curve (AUROC) 0.67 for both) had fair performance for prediction of mortality, whereas Sequential Organ Failure Assessment (SOFA) and Chronic Liver Failure (CLIF)-SOFA performed better for the prediction of mortality (AUROC 0.87 for both). SOFA and CLIF-SOFA also performed well when determined at the time of ICU admission (AUROC 0.86 and 0.85, respectively). Etiology of liver disease or AKI did not influence prognosis. CONCLUSION Critically ill patients with ACLF and AKI requiring CRRT have poor hospital survival, even with provision of extracorporeal support therapy. SOFA and CLIF-SOFA are good prognostic tools of mortality in this susceptible population.
.AIMS We aim to describe the clinical and histological findings in patients with the finding of any tubular oxalate deposits in kidney biopsy specimens. BACKGROUND The prevalence, manifestation, and outcome of secondary oxalate nephropathy have not been extensively studied. MATERIALS AND METHODS In this retrospective cohort study, we analyzed the clinical and histological findings in all patients with the finding of any tubular oxalate deposits in kidney biopsy specimens between July 1, 2017, and December 31, 2018, at Northwell Health Pathology Department (Manhasset, NY, USA). RESULTS The prevalence of oxalate deposition on a kidney biopsy was 4.07% (25/615), and in 88% of cases was a major finding. Prior to biopsy, oxalate was anticipated in only 1 case. The etiology of oxalosis was clarified retrospectively in 14 cases, most commonly due to GI surgery (n = 10) and increased oxalate intake (n = 4). In 11 cases, etiology remained unknown, although at least 3 cases were exposed to antibiotics associated with secondary oxalosis. There was no significant clinical/pathological or survival difference between known vs. unknown cause groups. The overall 3-month renal survival rate was 76.0 ± 8.5%. Multivariate Cox regression showed that creatinine at the time of biopsy (HR 1.79, 95% CI 0.71 - 4.51), background histological chronicity change (HR 1.82, 95% CI 0.70 - 4.72) and oxalate density (HR 2.27, 95% CI 0.49 - 10.55) are associated with end-stage kidney disease. CONCLUSION Oxalate deposition is common but rarely anticipated biopsy finding. Nephrologists need to consider surgical history and other secondary causes of oxalosis as causes of acute kidney injury and chronic kidney disease.
.BACKGROUND Serum creatinine has been solely used in clinical practice to identify chronic kidney disease (CKD) staging in the elderly population. Serum cystatin C is believed to more accurately define the CKD staging and is also ratified as an endogenous biomarker by Kidney Disease Improving Global Outcomes (KDIGO) guidelines. MATERIAL AND METHODS A total of 300 elderly Malay participants (age ≥ 65 years) with CKD, attending the Hospital University Sains Malaysia were included in the study. Demographic data and history were also recorded. Serum creatinine was assayed by Chemistry Analyzer Model Architect-C8000 (Jaffe method). While serum cystatin C was examined by Human cystatin C ELISA kit (Sigma-Aldrich) using Thermo Scientific Varioskan Flash ELISA reader. RESULTS Out of 300 study participants, 169 (56.3%) were females. Mean age of patients was 67.6 ± 6.7 years. 64 male (64.6%) and 35 female (35.4%) patients were between 70 and 79 years. When estimated by MDRD equation, the prevalence of CKD stage 3 (defined as eGFR = 30 - 59 mL/min/1.73m2) was 27.7%, while based on CKD-EPIcr, CKD-EPIcys, and CKD-EPIcr-cys equations, it was 28%, 36.3%, and 36.3%, respectively. The prevalence of CKD stage 4 (defined as eGFR = 15 - 29 mL/min/1.73m2) when estimated by MDRD was 37.6%, whereas based on CKD-EPIcr, CKD-EPIcys, and CKD-EPIcr-cys equations, it was 36.3%, 46.4%, and 46.4%, respectively. CKD stage 5 (defined as eGFR less then 15 mL/min/1.73m2) when estimated by the MDRD equation was 34.7%. While based on CKD-EPIcr, CKD-EPIcys, and CKD-EPIcr-cys equations, the prevalence of CKD stage 5 was 35.7%, 17.3%, and 17.3%, respectively. CONCLUSION The staging of CKD is different between the creatinine- and cystatin C-based equations. Creatinine-based equations classify patients as having CKD stage 5 twice as often as cystatin C-based equations.
.An orange-pigmented, short-rod-shaped, aerobic and non-motile bacterial strain, designated TK008T, was isolated from the shallow-sea hydrothermal systems off Kueishantao Island in Taiwan, China, and it was studied by using a polyphasic taxonomic approach. Cells were Gram-stain-negative, and catalase- and oxidase-positive. this website Strain TK008T exhibited highest 16S rRNA gene sequence similarity of 97.1 % to Paracoccus pacificus F14T. The phylogenetic trees based on 16S rRNA gene sequences showed that strain TK008T was a member of the genus Paracoccus. Digital DNA-DNA hybridization values between strain TK008T and two closely related species (Paracoccus zhejiangensis and Paracoccus tegillarcae) were 20.6 and 20.9 %. The average nucleotide identity values of strain TK008T compared with P. zhejiangensis and P. tegillarcae were 75.2 and 74.6 % respectively. The major isoprenoid quinone was ubiquinone-10. The predominant fatty acids (>10 %) were summed feature 8 (C18  1ω6c and/or C18  1ω7c). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, three unidentified phospholipids, two unidentified lipids and an unidentified glycolipid. The DNA G+C content of strain TK008T from genomic sequence data was 62.54 mol%. On the basis of polyphasic analysis, strain TK008T represents a novel species, for which the name Paracoccus aurantiacus sp. nov. is proposed. The type strain is TK008T (=CGMCC 1.13898T=JCM 33630T).
