Objective To define risk factors for ultrafiltration failure (UFF) during early stages of peritoneal dialysis (PD). Design Retrospective analysis of a group of patients whose peritoneal function was prospectively followed. Setting A tertiary-care public university hospital. Patients Nineteen of 90 long-term PD patients required a peritoneal resting period to recover UF capacity: 8 had this requirement before the third year on PD (early, EUFF group) and 11 had a late requirement (LUFF group). The remaining 71 patients, those with stable peritoneal function over time, constituted the control group. Main Outcome Measures Peritoneal UF capacity under standard conditions (monthly) and small solute peritoneal transport (yearly). Results None of the conditions appearing at the start of PD or during the observation period could be definitely identified as the cause of UFF. There were no differences in characteristics between the EUFF group and the other two groups, except for the higher prevalence of diabetes in the EUFF group. Residual renal function (RRF) declined in all three groups during the first 2 years, with rapid loss during the third year in the EUFF group. This rapid loss in RRF was coincident with UFF. Peritoneal solute and water transport at baseline was similar in the three groups. After 2 years on PD, individuals in the EUFF group showed a significantly lower UF and higher creatinine mass transfer coefficient values than those in the LUFF group. Diabetic patients in the control group showed remarkable stability in UF capacity over time. During the second year on PD, requirement for increases in dialysate glucose concentration was 3.4 ± 0.5% in the LUFF group, but as high as 25.5 ± 24.2% in the EUFF group. The accumulated days of active peritonitis (APID, days with cloudy effluent) were similar for the three groups after 1, 2, and 3 years on PD. Interestingly, diabetic patients in the control group showed an APID index significantly lower than the overall EUFF group. Diabetics in the control group also had significantly lower APID versus nondiabetics in the control group ( p = 0.016). Conclusions Our findings suggest that certain patients develop early UFF type I. Diabetic state and a higher glucose requirement to obtain adequate UF suggest that glucose on both sides of the peritoneal membrane could be responsible. The mechanisms for this higher requirement remain to be elucidated. The identification of a larger cohort of these early UFF patients should lead to a better exploration of the primary pathogenic mechanisms.

AbstractOver the last few decades, Mizoram has shown an increase in cases of type 2 diabetes mellitus; however, no in-depth scientific records are available to understand the occurrence of the disease. In this study, 500 patients and 500 healthy controls were recruited to understand the possible influence of their dietary and lifestyle habits in relation with type 2 diabetes mellitus. A multivariate analysis using Cox regression was carried out to find the influence of dietary and lifestyle factors, and an unpaired t test was performed to find the difference in the levels of biochemical tests. Out of 500 diabetic patients, 261 (52.3%) were males and 239 (47.7%) were females, and among the control group, 238 (47.7%) were males and 262 (52.3%) were females. Fermented pork fat, Sa-um (odds ratio (OR) 18.98), was observed to be a potential risk factor along with tuibur (OR 0.1243) for both males and females. Creatinine level was found to be differentially regulated between the male and female diabetic patients. This is the first report of fermented pork fat and tobacco (in a water form) to be the risk factors for diabetes. The unique traditional foods like Sa-um and local lifestyle habits like tuibur of the Mizo population may trigger the risk for the prevalence of the disease, and this may serve as a model to study other populations with similar traditional practices.

Objective To evaluate the impact of pre-dialysis glycemic control on clinical outcomes for type II diabetic patients on continuous ambulatory peritoneal dialysis (CAPO). Materials and Methods One hundred and one type II diabetic patients receiving CAPO for at least 3 months were enrolled in a single institute. The patients were classified into two groups according to status of glycemic control. In the good glycemic control group, more than 50% of blood glucose determinations were within 3.3 11.0 mmol/L and glycosylated hemoglobin (HbA 1 C) levels were within 5% -10% at all times. In the poor glycemic control group, less than 50% of blood glucose determinations were within 3.3 -11.0 mmol/L, or HbA1C levels were above 10% at least 6 months before peritoneal dialysis was started. In addition to glycemic control status, pre-dialysis serum albumin, cholesterol levels, residual renal function, peritoneal membrane function, and modes of glycemic control were also recorded. Results The patients with good glycemic control had significantly better survival than those with poor glycemic control (p < 0.01). There was no significant difference in pre-dialysis morbidity between two groups. No significant differences were observed in patient survival between patients with serum albumin above 30 g/L and those with serum albumin under 30 g/L; between those with cholesterol levels above or below 5.2 mmol/L; and between those with different peritoneal membrane solute transport characteristics as evaluated by a peritoneal equilibration test (PET). Furthermore, there was no significant difference in survival between patients who controlled blood sugar by diet and those who controlled it by insulin. Cardiovascular disease and infection are the major causes of death in both groups. Although good glycemic control predicts better survival, it does not change the pattern of mortality in diabetic patients maintained on CAPO. Conclusions Glycemic control before starting dialysis is a predictor of survival for type II diabetic patients on CAPO. Patients with poor glycemic control predialysis are associated with increased morbidity and shortened survival.

Phosphatidylcholine (PC), which has successfully been used in the past to increase ultrafiltration in continuous ambulatory peritoneal dialysis (CAPD) patients, has recently been found to prevent experimental adhesion formation after intraperitoneal irrigation with warm saline. The aim of this study was to determine the most effective route(s) of PC administration in the aforementioned model. Eighty Wistar rats underwent laparotomy and intraperitoneal irrigation with saline at 40°C, which in 20 rats was followed by closure of the abdomen (control group, Gc). In another 20 rats PC was given per os before and after irrigation (per os PC group, GoPc). In the third group PC was diluted in the irrigation fluid (intraperitoneal PC group, GIPC), and in the last group PC was given per os and intraperitoneally (combined PC group, Gcpc) Assessment of adhesions was performed 2 weeks after the irrigation. Adhesions were found in 12 rats in the Gc, 5 rats in the Gopc (p=0.05, Fisher's test), 17 rats in the GIPC, and 3 rats in the Gcpc (p=0.007, Fisher's test). The difference between Gopc and Gcpc was not statistically significant. The decreased adhesion formation after PC administration combined with the increased ultrafiltration may be of considerable importance in CAPD patients.

BackgroundUltrafiltration failure (UFF) is a serious complication of long-term peritoneal dialysis (PD). Peritoneal rest (PR) has been demonstrated as a valid treatment to reverse the functional changes that occur in UFF. The effects of PR on a normally functioning human peritoneum are unknown but are expected to be neutral. Our hypothesis was that PR positively modifies peritoneal function in patients with UFF, in contrast to the absence of effects when PR is applied under normal conditions.Patients and MethodsWe studied 84 PR periods, comparing 35 patients with UFF and 49 controls (resting for abdominal surgery with temporary discontinuation of PD). We analyzed peritoneal transport pre-PR and post-PR by calculating the mass transfer coefficients of creatinine (Cr-MTAC), the dialysate/plasma creatinine ratio (D/P Cr) and the ultrafiltration (UF).ResultsBaseline data was similar for the 2 groups, although the UFF group had a longer median time in PD (39 [18 – 60] vs 10 [5 – 23] months; p = 0.00001). Peritoneal rest induced a decrease in D/P Cr, Cr-MTAC and an increase in UF capacity in the UFF group ( p = 0.0001, p = 0.004 and p = 0.001, respectively), without causing changes in the control group. Peritoneal rest in patients with more than 6 months of UFF was not able to reduce peritoneal solute transport or improve UF capacity. Response to PR did not differ among UFF patients with or without a previous history of peritonitis. Peritoneal rest enabled patients with UFF to continue on PD for a median time of 23 months (range, 13 – 46 months).ConclusionsPeritoneal rest induces functional changes in patients with UFF but not in those with no functional abnormalities. This demonstrates that PR works only when abnormal but reversible functional conditions are present. However, the effect is highly dependent on how early PR is applied.

1. Chronic use of hyperosmolar glucose solutions in continuous ambulatory peritoneal dialysis may cause glycation of peritoneal structural proteins which could contribute to membrane dysfunction and ultrafiltration failure. To determine whether glycation can occur in the environment of the dialysate, we have carried out studies using albumin as a model protein. 2. Glycated albumin was measured in the serum and dialysate of 46 patients on continuous ambulatory peritoneal dialysis (31 non-diabetic patients, 15 diabetic patients). Dialysate and serum glycated albumin (ranges 1.0-12.7% and 0.9-10.2%, respectively) were related to each other (r = 0.988, P <0.001), but dialysate glycated albumin was significantly higher than serum glycated albumin (P <0.0001), with the dialysate to serum glycated albumin ratio being greater than unity in 76% of patients (mean ratio 1.14). This implies either preferential transfer of glycated albumin across the peritoneal membrane or intraperitoneal glycation during the dwell period. 3. In vitro, significant glycation occurred in dialysate during a 6 h incubation period (P <0.01) at a rate related to the glucose concentration in the dialysate (rs = 0.63, P <0.05). The glycation rate was not significantly affected (P = 0.05) by factors other than the glucose concentration. 4. Our results demonstrate that protein glycation occurs within the peritoneum during continuous ambulatory peritoneal dialysis. Further studies are required to establish the relationship of glycation of structural proteins in the peritoneal membrane to membrane function.

AIM: To investigate the changes of retinal nerve fiber layer (RNFL) among normal individuals, diabetic patients without diabetic retinopathy (NDR) and non-proliferative diabetic retinopathy (NPDR), and explore the possible risk factors of early diabetic retinopathy (DR). METHODS: In this cross-sectional study, 107 participants were divided in three groups. Totally 31 normal individuals (control group), 40 diabetic patients without DR (NDR group) and 36 patients with NPDR (NPDR group) were included. Optical coherence tomography (OCT) was used to detect RNFL thickness and other optic disc parameters among different groups. The potential association between RNFL loss and systemic risk factors were assessed for DR, including diabetes duration, body mass index (BMI), hemoglobin A1c (HbA1c), serum lipids, and blood pressure. RESULTS: The average and each quadrant RNFL thickness were thinner in NPDR group compared to control group of the right (P=0.00, P=0.01, P=0.01, P=0.02, P=0.04) and left eyes (P=0.00, P=0.00, P=0.00, P=0.03, P=0.04). The average, superior and inferior RNFL thickness were thinner in NDR group compared to the NPDR group of the right (P=0.00, P=0.02, P=0.03) and left eyes (P=0.00, P=0.00, P=0.01). Diabetic duration was negatively correlated with the superior, inferior, and average RNFL thickness of the right (r=-0.385, P=0.001; r=-0.366, P=0.001; r=-0.503, P=0.000) and left eyes (r=-0.271, P=0.018; r=0.278, P=0.015; r=-0.260, P=0.023). HbA1c was negatively correlated with the superior, inferior, and average RNFL thickness of the right (r=-0.316 P=0.005; r=-0.414, P=0.000; r=-0.418, P=0.000) and left eyes (r= -0.367, P=0.001; r=-0.250, P=0.030; r=-0.393, P=0.000). Systolic pressure was negatively correlated with the inferior and average RNFL thickness of the right eye (r=-0.402, P=0.000; r=-0.371, P=0.001) and was negatively correlated with the superior and average RNFL thickness of the left eye (r=-0.264, P=0.021; r=-0.233, P=0.043). CONCLUSION: RNFL loss, especially in the superior and inferior quadrants, may be the earliest structural change of the retina in diabetic patients, and is also associated with diabetic duration, HbA1c, and systolic pressure.

This study aimed to explore the risk factors attributed to osteoporosis in newly type 2 diabetes mellitus (T2DM) patients. This study aimed to recruit 244 T2DM patients and 218 non-diabetic controls. We collected demographic characteristics, medical history, bone mineral density and biomarkers including bone specific alkaline phosphatase (BALP), osteocalcin, N-terminal peptide of type I procollagen (P1NP), tartrate-resistant acid phosphatase 5b (TRCAP-5b), β-Cross Laps of type I collagen-containing cross-linked C-telopeptide (β-CTX), 25-hydroxyvitamin D, parathyroid hormone were recorded or detected. Bone mineral density (BMD) was our primary outcome. Based on the result of BMD, we divided both the control group and T2DM group into three subgroups: normal bone mass, osteopenia and osteoporosis. In control group, we found age, sex, menopausal status, BMI, P1NP, BALP, TRACP-5b, osteocalcin, and corrected serum calcium are differential among three subgroups. In T2DM group, we found age, sex, menopausal status, drinking status, BMI, HbA1c, TRACP-5b and OC were differential among three subgroups. In T2DM and control groups, age, female, postmenopausal status, BALP, TRACP-5b and osteocalcin were positively correlated while BMI was negatively correlated with osteoporosis. In control group, β-CTX was positively correlated with osteoporosis. In T2DM group, HbA1c and corrected serum calcium concentration were positively correlated with osteoporosis. After further adjustment of age, BMI in male, TRACP-5b was positively correlated with the risk of osteoporosis in newly diagnosed T2DM. After adjusted of age, BMI and menopausal status in female, OC was positively correlated with the risk of osteoporosis in newly diagnosed T2DM and controls. In female T2DM, BALP and P1NP were positively correlated with the risk of osteoporosis. In conclusion, age, BMI and menopausal status are common risk factors for osteoporosis in diabetic and non-diabetic patients, however TRACP-5b, BALP and osteocalcin are special risk factors for osteoporosis in newly diagnosed T2DM patients but not non-diabetic patients, which may be applied to identify osteoporosis risk in T2DM patients, but this result needs to be proven with fracture data.

Background Hypervolemia is a risk factor for left ventricular hypertrophy and hypertension in peritoneal dialysis patients. Icodextrin improves volume control by increasing ultrafiltration in peritoneal dialysis patients. Aim To examine the effects of twice-daily icodextrin administration on blood pressure and left ventricular hypertrophy in peritoneal dialysis patients with hypervolemia and ultrafiltration failure. Method and Results Administration of icodextrin twice daily resulted in a significant reduction in the left ventricular mass index (LVMI) of patients by the end of the third month ( p < 0.05). The reduction in LVMI was also significant for the once-daily icodextrin group ( p < 0.05). Mean blood pressure of patients receiving icodextrin twice daily was significantly reduced ( p < 0.05). By the end of the third month no significant changes were observed in mean blood pressure of the patients using once-daily icodextrin ( p > 0.05). No statistically significant changes were observed in weekly total creatinine clearances or Kt/V of patients in either group at the end of 3 months (NS). Conclusion Twice-daily icodextrin administration was clinically beneficial as shown by reduced blood pressure and prevention of the progress of left ventricular hypertrophy without causing any decrease in dialysis adequacy or any side effects. The icodextrin metabolite results did not suggest any further increase in their values when comparing once- to twice-daily administration of icodextrin. Although prescription of icodextrin once daily may yield good clinical results in the long term, this study showed that it may be more efficient to use twice-daily icodextrin for at least a specific period for the purpose of obtaining quicker results in patients with ultrafiltration failure, serious hypervolemia, or hard-to-control blood pressure conditions.

<b><i>Introduction:</i></b> Cognitive impairment (CI) is common in patients with CKD or diabetes mellitus (DM). However, the relevance between DM and CI in diabetic patients undergoing peritoneal dialysis (PD) has not been clearly established. This study aimed to explore the role of DM in CI, the association of glycemic control with CI, and clinical outcomes of CI in diabetic PD patients. <b><i>Methods:</i></b> Continuous ambulatory PD (CAPD) patients followed up in our PD center between 2014 and 2016 were enrolled. The participants were followed until an endpoint was reached or December 2017. Demographic data and clinical characteristics were collected, and laboratory parameters were measured. The Montreal Cognitive Assessment (MoCA) was used to evaluate global cognitive function, and a score of &#x3c;26 was considered to indicate CI. A propensity score matching according to age, gender, and mean arterial pressure was conducted between the DM and non-DM groups. <b><i>Results:</i></b> A total of 913 CAPD patients were enrolled, of whom 186 (20.4%) had diabetes. After appropriate matching, 175 patients in the DM group and 270 patients in the non-DM group were included. Patients with diabetes had a higher prevalence of CI and lower scores for visuospatial/executive function, naming, language, delayed recall, and orientation. Higher HbA1c (odds ratio [OR], 1.547; 95% confidence interval [95% CI], 1.013–2.362) and cardiovascular disease (CVD; OR, 2.926; 95% CI, 1.139–7.516) significantly correlated with a risk of CI in diabetic patients. During a median of 26.0 (interquartile range 13.5–35.6) months of follow-up, diabetic patients with CI demonstrated a significantly lower survival rate than those without CI, and CI was an independent risk factor for mortality after adjustment (hazard ratio, 7.224; 95% CI, 1.694–30.806). However, they did not show worse technique survival or higher peritonitis rate than patients without CI. <b><i>Conclusions:</i></b> HbA1c and CVD are independent risk factors for CI in diabetic patients undergoing CAPD, and CI is independently associated with a higher risk of mortality.

BACKGROUND Diabetes mellitus (DM) single-handedly accounts for 75 – 90 % of excess coronary artery disease (CAD) risk seen in persons suffering from it and it also enhances and amplifies the effects of other traditional cardiovascular risk factors. After adjusting for concomitant risk factors such as hypertension and hyperlipidemia, there still remains an excess risk for cardiovascular disease (CVD) in people with diabetics. In this study, we wanted to evaluate left ventricular (LV) systolic and diastolic dysfunction in normotensive diabetic patients. METHODS A cross sectional comparative study was performed from January 2016 to September 2017 on 50 diabetics and 50 age and sex matched healthy controls. Adult patients of both sexes with diabetes mellitus who are normotensive were included as cases. Patients with known heart disease, chronic kidney disease, thyroid disorders were excluded from the study. 2D transthoracic echocardiogram (ECHO) with M mode was used for assessing systolic and diastolic function. RESULTS Mean ejection fraction was lower in patients group (59.76) as compared to control group (64.74) with 8 % of cases with a value of< 50 %. Fractional shortening was also lower in patients (29.14) compared to controls (34.86) with 12 % patients having a value of < 25 %. E/A ratio was 1.12 in patients when compared to 1.36 in controls with 32 % of patients having value < 1. Mean isovolumic relaxation time was 96.52 in patients when compared to 87.42 in controls with 24 % patients having value > 100 msec. CONCLUSIONS Normotensive diabetics are prone to left ventricular dysfunction. Diastolic dysfunction is more common than systolic dysfunction.
