RESUMEN

The gut microbiota has nutritional and protective functions. In patients with end-stage renal disease, changes in the gut microbiota disrupt their protective functions. Probiotics help maintain normal bowel function. However, their role in patients with end-stage renal disease is controversial. We investigated whether Clostridium butyricum affects the nutrition and immune function of patients with end-stage renal disease undergoing maintenance dialysis between 2014 and 2015; thirty-seven patients were included. The patients were divided into two groups: one in which C. butyricum was administered and one in which it was not. One tablet of the probiotics, which contained 20 mg of C. butyricum, was administered orally three times daily for 2 years in the C. butyricum group. The 16S rRNA genes were sequenced from stool samples of 14 (37.8%) patients in the C. butyricum group and 23 (62.2%) patients in the control group. The differences in the gut microbiota of the two groups were analyzed. The α-diversity index indicated that the C. butyricum group had significantly more operational taxonomic units and higher albumin and transferrin levels than the control group. The effector to target cell ratio was significantly higher in the C. butyricum group. In addition, interleukin-6 levels were significantly lower in the C. butyricum group, and inflammation was less severe in this group. The patients undergoing maintenance dialysis with C. butyricum had abundant gut microbiota. They also had a good nutritional status, low systemic inflammation, and a good immunological status.

RESUMEN

BACKGROUND: Percutaneous endoscopic gastrostomy with jejunal extension (PEG-J) is often used to treat patients with neurological impairment and difficulty in swallowing. However, these patients often develop copper deficiency. This report describes a case of isolated neutropenia, which is a rare manifestation of copper deficiency. CASE SUMMARY: Our patient was a 19-year-old boy with neurological impairment and gastroesophageal reflux. He received PEG-J feeding, including an enteral supplement containing copper and zinc. However, as his serum zinc level was low (53 µg/dL) at the age of 19 years and 2 mo, we changed to a zinc-rich supplement containing 22 mg/d of zinc and 1.0 mg/d of copper. The supplement comprised a mixture of isocal 1.0 junior (5 packs/d), Tezon [2 packs (250 mL)/d], and cocoa powder. Seven months later, he had neutropenia (606/mm3) with a serum copper level of 16 µg/dL. There were no other manifestations of copper deficiency, including anemia. Copper deficiency and neutropenia both improved following the administration of cocoa powder and Tezon. CONCLUSION: In patients receiving long-term PEG-J feeds, white blood cell counts, hemoglobin, and serum levels of copper and zinc should be regularly monitored.

RESUMEN

BACKGROUND: Increasing the blood flow rate (BFR) is a useful method for increasing Kt/V and the clearance for low molecular solutes. Hemodialysis patients are often anemic due to hypoerythropoiesis and their chronic inflammatory state. Hepcidin, a hormone that regulates iron homeostasis, is considered as an indicator of iron deficiency in patients with end-stage renal disease. This study aimed to investigate the effects of an increased BFR during hemodialysis on serum hepcidin levels and anemia. METHODS: Between April 2014 and March 2016, 22 chronic dialysis patients (11 men [50.0 %]; mean [± standard deviation] age, 72 ± 12 years) undergoing maintenance hemodialysis treatment, thrice weekly, were enrolled and followed prospectively for 24 months. In April 2014, the BFR was 200 mL/min; in April 2015 this was increased to 400 mL/min, which was within acceptable limits. The dialysate flow rate remained stable at; 500mlL/min. Blood samples were collected in March 2015 and 2016. The primary endpoint was the comparison of the amounts of erythropoiesis-stimulating agent (ESA) required. RESULTS: The increased BFR increased the Kt/V and contributed to significantly decreased urea nitrogen (UN) (p = 0.015) and creatinine (Cr) (p = 0.005) levels. The dialysis efficiency was improved by increasing the BFR. Ferritin (p = 0.038), hepcidin (p = 0.041) and high-sensitivity interleukin-6 (p = 0.038) levels were also significantly reduced. The ESA administered was significantly reduced (p = 0.004) and the Erythropoietin Resistant Index (ERI) significantly improved (p = 0.031). The reduction rates in UN (p < 0.001), Cr (p < 0.001), and beta-2 microglobulin (p = 0.017) levels were significantly greater post the BFR increase compared to those prior to the BFR increase. However, hepcidin was not affected by the BFR change. CONCLUSIONS: Increasing BFR was associated with hemodialysis efficiency, and led to reduce inflammatory cytokine interleukin-6, but did not contribute to reduce C-reactive protein. This reduced hepcidin levels, ESA dosage and ERI. Hepcidin levels were significantly correlated with ferritin levels, and it remains to be seen whether reducing hepcidin leads to improve ESA and iron availability during anemia management.

RESUMEN

BACKGROUND: The incidence of hemorrhoids requiring hemorrhoidectomy among the elderly has been increasing. Old age is sometimes considered a contraindication for surgery. The relationship between age and complications of hemorrhoidectomy for elderly patients is not well established. This study aimed to compare the clinicopathological features and postoperative outcomes of hemorrhoidectomy in the elderly (≥75 years old) and non-elderly patients (<75 years old). METHODS: A total of 100 patients who underwent hemorrhoidectomy for hemorrhoids of Goligher classification grades 3 and 4 at our institution between 2014 and 2018 were enrolled. The clinical characteristics were compared between the elderly and non-elderly patients. Pain scores were measured at 6, 12, 24, and 48 h after surgery. The risk factors for postoperative complications were identified. RESULTS: A total of 34 patients were classified as elderly patients. In the elderly group, aspartate aminotransferase levels were higher while the albumin levels and cholinesterase levels were lower and the platelet counts were significantly lower. The blood urea nitrogen levels were higher and estimated glomerular filtration rates and hemoglobin levels were significantly lower in the elderly group. The pain scores significantly decreased at 48 h postoperatively compared to those recorded at 6 h postoperatively in both groups. Multivariate analysis identified Goligher classification grade 4 and high neutrophil to lymphocyte ratio at the indicators of complications. CONCLUSIONS: Hemorrhoids due to impairment of liver function and kidney function were dominant in elderly patients. Aging itself was not a risk factor for postoperative complications.

RESUMEN

Objective: Patients with severe motor and intellectual disabilities (SMID) often develop complications, including paralysis of the extremities due to abnormal muscular tonicity. Furthermore, the incidence of sudden death, which may be caused by pulmonary thromboembolism (PTE), is approximately 4.2%. Deep vein thrombosis (DVT) is attracting attention as an embolic source. In this study, DVT was confirmed in SMID patients by lower extremity venous ultrasound. The oral anticoagulant, warfarin, and novel oral anticoagulant, edoxaban tosilate hydrate, were administered, and their efficacies and safeties were evaluated. Materials and Methods: DVT patients were randomly allocated to warfarin and edoxaban groups. The frequency of hemorrhagic events and incidence of adverse events were investigated to evaluate efficacy and safety. Results: DVT was detected in 14 (8.4%) out of 167 patients. Four (0.067/person-month) hemorrhagic events occurred in the warfarin group from subcutaneous hemorrhage due to bruises caused by postural changes. Three (0.042/person-month) events occurred in the edoxaban group due to nasal hemorrhage caused by tracheal aspiration. There was no significant difference (p=0.5383) between groups. Conclusion: No significant differences were observed in hemorrhagic events between SMID patients with DVT treated with warfarin and edoxaban.

RESUMEN

Sudden death associated with patients with severe motor and intellectual disabilities (SMID) have been thought to be caused in part by venous thromboembolism (VTE), but actual situation of VTE in SMID is not clear. We examined the prevalence and location of deep venous thrombosis (DVT), and the relation of the development of crural veins in 16 patients with SMID, using ultrasonography. The maximum diameter of soleal vein was 1.6±0.5 mm. In most cases, DVT was found in the femoral veins. We could not detect thrombus in the soleal veins. In the present study, the detection ratio of DVT was high in patients with SMID who had restricted mobility capability and were bedridden, and we found the veins centrally from popliteal veins in DVT in SMID, not soleal veins, as the initial sites of the DVT. In the literature, the mean diameter of soleal veins, in healthy adults is 6.7±1.8 mm, that in contrast in SMID being smaller. Underdevelopment of intramuscular veins is possibly related to the mechanism of DVT in SMID. In the current guidelines for the management of VTE, there is limited in scope of ambulatory adults and no application cases who exhibit to SMID restricted mobility of the lower extremities and are bedridden associated with cerebral palsy and developmental motor disabilities, and such patients have associated high risk of the complications of DVT. According to our present study, it is necessary to provide appropriate guidelines for DVT in SMID considering characteristic features. (This is a translation of Jpn J Phlebol 2017; 28: 29-34.).

RESUMEN

Sudden death in patients with severe motor and intellectual disabilities (SMID) is sometimes caused in part by pulmonary thromboembolism (PTE), and deep venous thrombosis (DVT) has drawn attention as a possible embolic source. Warfarin, which is a conventional therapeutic agent, is not easy to control appropriately, and daily management can be especially difficult in SMID patients. On the other hand, edoxaban tosilate hydrate, which has been newly approved for insurance coverage for the treatment of DVT, is not listed in the Guidelines for the Diagnosis, Treatment and Prevention of Pulmonary Thromboembolism and Deep Vein Thrombosis (DVT-PTE guidelines). The aim of this study is to evaluate the efficacy and safety of anticoagulation therapy (warfarin vs. edoxaban) in DVT treatment in SMID patients by means of an open-label, randomized controlled trial. The primary endpoint is the incidence of hemorrhagic events during 12 months of follow up.

RESUMEN

Most patients with severe motor and intellectual disabilities (SMID) have restricted mobility capability and have been bedridden for long periods because of paralysis of the extremities caused by abnormal muscular tonicity due to cerebral palsy and developmental disabilities. Such patients are associated with a high risk of complications like deep vein thrombosis (DVT). Here, we report twelve patients (42.9%) with DVT among 28 patients with SMID during prolonged bed rest. However, we did not detect thrombosis in the soleal veins, finding it mostly in the femoral and common femoral veins. We applied anticoagulant therapy (warfarin), and carefully followed up the cases with DVT, regulating the warfarin dosage at prothrombin time-international normalized ratio (PT-INR) values around two to prevent recurrence of chronic thrombosis. Regarding laboratory data for the coagulation system, there were no cases above 5 µg/ml for the D-dimer and there were significant differences between the DVT and non-DVT groups in the D-dimer levels. The plasma levels of D-dimer in patients with DVT diminished to less than 1.0 µg/ml after warfarin treatment. Concerning sudden death (4.2%) in patients with SMID, we have to be very careful of the possibility of pulmonary thromboembolism due to DVT. Therefore, we should consider the particularity of the underdeveloped vascular system from underlying diseases for the evaluation of DVT. A detailed study of DVT as a vascular complication is very important for the smooth medical care of SMID, and serial assessment of compression Doppler ultrasonography of the lower extremities, as a noninvasive examination and measurement of D-dimer, is very helpful.

RESUMEN

Indoleamine 2, 3-dioxygenase (IDO) suppresses adaptive immune response. However, there was no study to examine whether IDO activity is associated with immune parameters in dialysis patients. In this study, we estimated serum IDO activity by the kynurenine/tryptophan ratio (KTR), and compared KTR with natural killer (NK) cell activity, soluble interleukin-2 receptor (sIL-2R) and serum levels of trace elements such as selenium (Se) and zinc (Zn) that affect T-cell function in 28 hemodialysis (HD) patients (age: 72 ± 13 years old, time on HD: 79 ± 89 months). NK cell activity was decreased in 35.7% of the patients. KTR values were almost 10-times higher in HD patients (380.81 ± 385.46 mM/M) than those in the referred controls (32.9 ± 9.10 mM/M). KTR was lower in patients with impaired NK cell activity than those without (279 ± 111 vs. 565 ± 603 mM/M, P = 0.07). There was no relationship between KTR and sIL-2R and Zn, while KTR was significantly and negatively correlated with serum Se levels that can impair cellular immunity (r = -0.41, P < 0.05). Our findings suggest that increased IDO activity with Se deficiency may be associated with impaired NK cell function in HD patients.

RESUMEN

Most patients with severe motor and intellectual disabilities (SMID) have restricted mobility capability and have been bedridden for long periods because of paralysis of the extremities caused by abnormal muscular tonicity due to cerebral palsy and developmental disabilities, and such patients are associated with a high risk for the complications of deep vein thrombosis (DVT). Here, we report 8 patients (34.8%) with DVT among 23 patients with SMID during prolonged bed rest. However, we did not detect thrombosis in the soleal veins, finding it mostly in the superficial femoral and common femoral veins. Regarding laboratory data for the coagulation system, there were no cases with D-dimer above 5 µg/ml. Concerning sudden death in patients with SMID, we have to be very careful of the possibility of pulmonary thromboembolism due to DVT.
