Prediction of Postoperative Mortality in Patients With Organ Failure Following Pancreaticoduodenectomy

Background Failure to rescue (FTR) patients with postoperative complications contribute to a significant proportion of postoperative mortality. Our main objective was to determine the risk factors for FTR among patients undergoing pancreaticoduodenectomy who suffered a life-threatening complication requiring intensive care unit (ICU) management. Materials and Methods Consecutive patients undergoing pancreaticoduodenectomy from 2011 to 2020 were reviewed retrospectively. Causes of organ failure were described as the one that most commonly contributed to patient’s transfer to ICU or death. Two groups were created based on whether patients had FTR and risk factors for FTR were compared. The impact of baseline characteristics, operative characteristics, and risk scoring on FTR was analyzed using multiple logistic regression. Results There were 19/58 (33%) FTR patients. Baseline, operative characteristics, postoperative complications, and length of hospital and ICU stay were similar between groups. However, a higher proportion of FTR patients experienced a postoperative pancreatic fistula (POPF) (16% vs 2.6%, P = .062). Among patients who experienced a POPF, the FTR group had a trend in delayed time from diagnosis to treatment (7 vs 23 hours, P=.131). Renal complications (OR 6.12, 95% CI, 1.23 to 38.43, P = .035) and time from POPF diagnosis to treatment (OR 1.05, 95% CI, 1.00 to 1.11, P = .036) were independent predictors of FTR by multivariable analysis. Conclusion The occurrence of certain postoperative complications such as renal complications as well as delayed timing of the management of POPF is predictive of FTR following pancreaticoduodenectomy, especially as delayed timing to treatment is a risk factor for FTR.

The Study of Correlation of Incidence, Severity of Renal, Cardiovascular Complications with Duration, Severity of Type 2 Diabetes Mellitus in a Tertiary Care Hospital

Background: Type 2 Diabetes Mellitus (DM) is a disorder of the endocrine characterised by hyperglycaemia which results from variable degrees of insulin resistance and insulin deficiency.Chronic hyperglycaemia in diabetes may lead to multi organ damage resulting in renal, cardiovascular and other complications.In our study, we aim to look for correlation between the degree of glycemic control, duration of type 2 DM, incidence, severity of renal, cardiovascular complications in type 2 DM patients. The objective of our study is to analyse the correlation between glycemic control and occurrence of cardiovascular, renal complications in type 2 DM patients. Materials and Methods: 50 type 2 DM patients were selected from the Medicine outpatient of Saveetha Medical College and Hospital from January 2021 to March 2021.The study was explained and informed consent was obtained. Ethical committee clearance was obtained.The duration of the disease, regularity of treatment are recorded, serum HbA1c was done to evaluate the degree of glycemic control.Renal function tests like estimation of urea and creatinine are done to look for renal complications. Echocardiogram was done to evaluate the cardiac status of the patient. Expected Outcome: We expect a direct correlation between the severity of uncontrolled hyperglycaemia, duration of the disease with the incidence of renal and cardiovascular complications. Results: 50 patients who were selected for the study having type 2 Diabetes Mellitus, were made into two groups - people with uncontrolled diabetes (HbA1c >7.5%) were more prone in developing renal and cardiac complications which were assessed by urea, creatinine, urine protein levels and ejection fraction (EF %) values. The significant cut off values to cause complications were taken as for urea (>40mg/dl), creatinine (>1mg/dl), urine protein (+/++/+++), EF value(>50%) and the presence/absence of regional wall motion abnormality (RWMA) was noted. It was also observed that longer age duration of the disease, more was the risk to develop cardiac complications than disease of shorter duration. Hence a poor control of hyperglycaemia made the subject prone to renal and cardiovascular complications. Conclusion: We arrive at a direct correlation between the severity and extent of uncontrolled hyperglycaemia with the incidence of severity and complications in the form of nephropathy and cardiac dysfunction.

Impact of cardiometabolic multimorbidity and ethnicity on cardiovascular/renal complications in patients with COVID-19

ObjectiveUsing a large national database of people hospitalised with COVID-19, we investigated the contribution of cardio-metabolic conditions, multi-morbidity and ethnicity on the risk of in-hospital cardiovascular complications and death.MethodsA multicentre, prospective cohort study in 302 UK healthcare facilities of adults hospitalised with COVID-19 between 6 February 2020 and 16 March 2021. Logistic models were used to explore associations between baseline patient ethnicity, cardiometabolic conditions and multimorbidity (0, 1, 2, >2 conditions), and in-hospital cardiovascular complications (heart failure, arrhythmia, cardiac ischaemia, cardiac arrest, coagulation complications, stroke), renal injury and death.ResultsOf 65 624 patients hospitalised with COVID-19, 44 598 (68.0%) reported at least one cardiometabolic condition on admission. Cardiovascular/renal complications or death occurred in 24 609 (38.0%) patients. Baseline cardiometabolic conditions were independently associated with increased odds of in-hospital complications and this risk increased in the presence of cardiometabolic multimorbidity. For example, compared with having no cardiometabolic conditions, 1, 2 or ≥3 conditions was associated with 1.46 (95% CI 1.39 to 1.54), 2.04 (95% CI 1.93 to 2.15) and 3.10 (95% CI 2.92 to 3.29) times higher odds of any cardiovascular/renal complication, respectively. A similar pattern was observed for all-cause death. Compared with the white group, the South Asian (OR 1.19, 95% CI 1.10 to 1.29) and black (OR 1.53 to 95% CI 1.37 to 1.72) ethnic groups had higher risk of any cardiovascular/renal complication.ConclusionsIn hospitalised patients with COVID-19, cardiovascular complications or death impacts just under half of all patients, with the highest risk in those of South Asian or Black ethnicity and in patients with cardiometabolic multimorbidity.

Use of biologic agents and methotrexate improves renal manifestation and outcome in patients with rheumatoid arthritis: a retrospective analysis

Background and purpose We examined whether advances in treatment strategies from older disease-modifying antirheumatic drugs (DMARDs) to new biologic agents and methotrexate improved renal complications and outcome in patients with rheumatoid arthritis (RA). Methods We reviewed records of 156 patients with RA who underwent kidney biopsy at our institute between January 1990 and December 2019. All patients were assigned to one of three periods: period 1, 1990–1999 (n = 48); period 2, 2000–2009(n = 57); period 3, 2010–2019 (n = 51). Results Membranous nephropathy, nephrosclerosis, AA-amyloidosis, and IgA nephropathy were the four major renal manifestations of RA. AA-amyloidosis was diagnosed by kidney biopsy in 21 patients: period 1, 7 patients (15%); period 2, 10 patients (18%); and period 3, 4 patients (8%). The 4 patients in period 3 were in the years 2010–2014, and no new case of AA-amyloidosis was recorded from 2015 to 2019. In all 21 of the patients with AA-amyloidosis, neither a biologic agent nor methotrexate was administered. Fifteen of the 21 patients required dialysis, and 13 died in periods 1–3 because of amyloid-related cardiac dysfunction less than 2 years after the initiation of dialysis. Two of them are doing well using biologic agent despite dialysis. The remaining three patients who received a biologic agent or methotrexate does not progress to end-stage renal failure. In addition, the other renal complications showing progression to dialysis also decreased over time. Conclusion Advances in treatment strategies have improved renal outcome and reduced mortality in patients with RA.

Kidney complications after COVID-19

This article discusses renal complications after Covid-19. It has now become clear that infection with the SARS-Cov-2 virus, which causes COVID-19, is almost identical - and this tells scientists which organs are most at risk. Specifically, the respiratory tract, intestines and, most likely, the kidneys, since it is there that both proteins necessary for the virus are present. Even the Ebola virus, found in the eye fluid of ex-patient’s months after recovery, causes blindness in 40 percent of those infected later. Therefore, given that SARS-CoV-2 is more likely to damage the lungs, doctors have speculated that the virus may cause irreversible changes in the respiratory system.

How the treatment of gastrointestinal tract disorders may be infl uenced by the kidneys

Summary: The treatment of gastrointestinal tract (GIT) diseases may, under specific conditions, be significantly influenced by the kidneys or by kidney disorders. One of the potential scenarios of such interaction is the concurrent involvement of the kidneys and the GIT organs within one disorder, another option being the negative impact of impaired renal function on the prognosis of the GIT disease and, finally, the need for an adequate choice and dose adjustment of renally eliminated medication to avoid nephrotoxicity. Renal impairment may occur as an adverse effect of the treatment of the GIT condition and may limit further therapy. In this context we have recently focused on the following clinical situations: the development of acute kidney injury during treatment with proton pump inhibitors, renal complications of inflammatory bowel disease management and the development of acute phosphate nephropathy due to the use phosphate containing laxatives. An early identification of the mechanisms leading to renal injury can prevent the development of irreversible renal lesions and facilitate an efficient treatment of the GIT. Key words: treatment of gastrointestinal tract disorders – acute kidney injury – proton pump inhibitors – renal complications of inflammatory bowel disease – acute phosphate nephropathy

Children with Intestinal Failure Maintain Their Renal Function on Long-Term Parenteral Nutrition

Background: Long-term parenteral nutrition (PN) has been associated with renal complications, including hypercalciuria, nephrocalcinosis, proteinuria and reduced glomerular filtration rate (GFR). Pediatric data are scarce and mostly short-term. Our study aimed to evaluate renal complications in children with intestinal failure (IF) receiving long-term PN. Methods: A cross-sectional study was performed in a tertiary pediatric IF clinic of patients receiving home-PN treatment for more than 1 year. Data regarding medical background, anthropometrics, laboratory investigations and abdominal sonography were retrieved. Results: Complete data were available for 15 children (67% males), with a median age of 6 (range 1.5–15) years and a median (IQR) PN duration of 4 (1.5–6) years. Low-grade proteinuria was identified in 61% and microalbuminuria in 30% of the cohort. Hypercalciuria and hyperoxaluria were present in 50% and 46%, respectively. One patient had nephrocalcinosis. The estimated GFR was normal in all but one patient who had pre-existing kidney disease. Conclusions: Pediatric IF patients can present with preserved kidney function after years of PN treatment. Despite the high prevalence of hypercalciuria, nephrocalcinosis was not common. Base line and long-term monitoring of various aspects of renal function would be essential to characterize the effects of prolonged PN on kidney functions in pediatric patients.

Renal complications of sickle cell disease

The nephropathy and renal complications of sickle cell disease are associated with various events such as hypoxic or ischemic conditions and reperfusion injury. Erythrocyte sickling occurs following these events and renal medullary acidosis.
