Foetal Outcome

Background: Pregnancy Related Acute Kidney Injury (PRAKI) is a major cause of maternal and foetal morbidity and mortality in developing countries. The incidence has declined due to improvements in reproductive health but it is still associated with significant perinatal mortality and maternal morbidity. It may be due to decrease in renal perfusion or ischemic tubular necrosis from a variety of conditions encountered during pregnancy. Our study aims at determining the predisposing factors and causes of AKI during pregnancy and its impact on maternal and foetal outcome.Methods: A retrospective cohort study over a period of 5 years was conducted on pregnant women with AKI as per inclusion and exclusion criteria. The detailed history, events, mode of delivery, cause leading to AKI, management, hospital stay, maternal and foetal outcome were studied in detail and evaluated. These patients were classified according to RIFLE criteria and were followed up for hospital stay and residual morbidities.Results: The incidence of PRAKI in the study was 0.07% (36 out of 50,735 deliveries) and among obstetric ICU patients, it was 6.8%. Most of the majority of the cases were unbooked (66.7%) and multipara (61.1%). Maternal morbidity was seen in 66.7% and mortality was 27.8%. Poor foetal outcome was seen in 44.4%.Conclusions: Haemorrhage is the most common cause of PRAKI, followed by toxaemia of pregnancy and sepsis. Early detection and meticulous management of haemorrhage, hypertension and sepsis reduce the incidence of PRAKI and associated maternal mortality.

Introduction: Acute kidney injury is a common and life-threatening event in patients with liver cirrhosis occurring in approximately 20-50% of hospitalized patients of liver cirrhosis. Pre-renal acute kidney injury, the hepatorenal syndrome type of acute kidney injury and acute tubular necrosis represent the common causes. The aim of this study was to study the profile of acute kidney injury in patients with liver cirrhosis. Methods: Consecutive patients of liver cirrhosis admitted in Liver unit of Bir Hospital were studied to see the presence of acute kidney injury in this hospital based descriptive cross-sectional study. Clinical and laboratory parameters along with various clinical outcome were compared between different groups categorized by the severity of liver disease and renal dysfunction. Results: Out of 302 liver cirrhosis patients, 56 (18.5%) had acute kidney injury among which 23 (46%) were found to have pre-renal acute kidney injury, 15 (30%) with hepatorenal syndrome– acute kidney injury and 12 (24%) with intrinsic renal disease. Patients with higher stages of acute kidney injury had longer duration of hospital stay and hepatorenal syndrome-acute kidney injury was seen in patients with higher grade of ascites and with hyponatremia. Conclusions: Acute kidney injury is a common occurrence in patients with advanced liver cirrhosis with pre-renal acute kidney injury being the commonest cause. Median hospital stay is directly affected by the severity of acute kidney injury and hepatorenal syndrome–acute kidney injury was seen in patients with higher grade of ascites and hyponatremia. Early identification of patients at high risk for acute kidney injury may help to reduce mortality and contain costs.

Introduction: Acute kidney injury (AKI) is common in hospitalised children with adverse short and long term outcomes. Detection of the incidence, etiological profile and outcome of AKI is important for starting preventive and therapeutic modalities. This study aimed to determine the incidence, etiology and short term outcome of AKI at a tertiary centre in Eastern Nepal. Methods: A prospective observational study was conducted in children from two months to 14 years of age admitted in paediatric wards and paediatric intensive care unit (PICU) of a tertiary centre of Eastern Nepal. AKI was defined according to pRIFLE criteria. Results: From May 2015 to March 2016, 942 patients enrolled in Paediatric wards and PICU were evaluated. The overall incidence of AKI was found to be 5.9% and 18.23% in patients admitted in PICU. AKI was commonest among cases having infectious etiology compromising 73.2% (n = 41), 17.85% (n = 10) due to primary renal disease, 5.35% (n = 3) secondary to congenital heart disease, and 3.57% due to other causes. Among AKI patients, 55.4% (n = 31) required inotropic support, 33.9% (n = 19) required mechanical ventilation while 5.36% (n = 3) underwent dialysis. Out of 56 AKI patients 71.4% (n = 40) had improved clinical outcome and 28.6% (n = 16) expired. Patient with AKI had significant longer duration of hospital stay as compared to non AKI (Seven days vs. three days, p < 0.001). Mortality was high among AKI patients on injury and failure stage (p = 0.003) and those requiring mechanical ventilation and inotropic support (p < 0.001). Conclusions: The incidence of AKI was found to be high in paediatric patients. Presence of AKI increased the duration of hospital stay and mortality in hospitalised children often requiring mechanical ventilation and inotropic support.

Objectives: Extracorporeal cardiopulmonary resuscitation (eCPR) is increasingly used due to its beneficial outcomes and results compared with conventional CPR. Data after eCPR for acute kidney injury (AKI) are lacking. We sought to investigate factors predicting AKI in patients who underwent eCPR. Methods: From January 2016 until December 2020, patients who underwent eCPR at our institution were retrospectively analyzed and divided into two groups: patients who developed AKI ( n = 60) and patients who did not develop AKI ( n = 35) and analyzed for outcome parameters. Results: Overall, 63% of patients suffered AKI after eCPR and 45% of patients who developed AKI needed subsequent dialysis. Patients who developed AKI showed higher values of creatinine (1.1 mg/dL vs 1.5 mg/dL, p ⩽ 0.01), urea (34 mg/dL vs 42 mg/dL, p = 0.04), CK (creatine kinase) (923 U/L vs 1707 U/L, p = 0.07) on admission, and CK after 24 hours of ECMO support (1705 U/L vs 4430 U/L, p = 0.01). ECMO explantation was significantly more often performed in patients who suffered AKI (24% vs 48%, p = 0.01). In-hospital mortality (86% vs 70%; p = 0.07) did not differ significantly. Conclusion: Patients after eCPR are at high risk for AKI, comparable to those after conventional CPR. Baseline urea levels predict the development of AKI during the hospital stay.

Objective We sought to characterize the incidence and risk factors associated with developing maternal morbidity following preterm prelabor rupture of membranes. Study Design Retrospective case–control study of patients with preterm prelabor rupture of membranes at a single institution from 2013 to 2019 admitted at ≥23 weeks gestational age. The primary outcome was a composite of maternal morbidity which included: death, sepsis, intensive care unit (ICU) admission, acute kidney injury, postpartum dilation and curettage, postpartum hysterectomy, venous thromboembolism, postpartum hemorrhage, postpartum wound complication, postpartum endometritis, pelvic abscess, postpartum pneumonia, readmission, and/or need for blood transfusion were compared with patients without above morbidities. Severe morbidity was defined as: death, ICU admission, venous thromboembolism, acute kidney injury, postpartum hysterectomy, sepsis, and/or transfusion >2 units. Demographics, antenatal, and delivery characteristics were compared between patients with and without maternal morbidity. Bivariate statistics and regression models were used to compare outcomes and calculate adjusted odd ratios. Results Of 361 included patients, 64 patients (17.7%) experienced maternal morbidity and nine (2.5%) had severe morbidity. Patients who experienced maternal morbidity were significantly (p < 0.05) more likely to be older, have private insurance, have BMI ≥40, have chorioamnionitis at delivery, and undergo cesarean or operative vaginal delivery when compared with patients who did not experience morbidity. After controlling for confounders, cesarean delivery (aOR 2.38, 95% CI[1.30,4.39]), body mass index ≥40 at admission (aOR 2.54, 95% CI[1.12,5.79]), private insurance (aOR 3.08, 95% CI[1.54,6.16]), and tobacco use (aOR 3.43, 95% CI[1.58,7.48]) were associated with increased odds of maternal morbidity. Conclusion In this cohort, maternal morbidity occurred in 17.7% of patients with preterm prelabor rupture of membranes. Private insurance, body mass index ≥40, tobacco use, and cesarean delivery were associated with higher odds of morbidity. These data can be used in counseling and to advocate for smoking cessation.

Spontaneous Improvement

Crescentic glomerulonephritis (GN) without immune reactants or deposits (referred to as pauci-immune) is typically characterized by the presence of anti-neutrophilic cytoplasmic antibodies (ANCA). While ANCA-negative patients might be expected to have a more benign course, they often have poor renal outcomes, especially without treatment with steroids and immune-modulating therapy. Pauci-immune crescentic GN can also co-exist with other autoimmune conditions, including rheumatoid arthritis (RA). Here, we describe an ANCA-negative patient with RA who developed dialysis-requiring acute kidney injury (AKI) with findings consistent with focal pauci-immune crescentic GN (i.e., no IgG or immune complex on kidney biopsy). Coexistent conditions included Klebsiella sepsis attributed to pneumonia, rhabdomyolysis, leukocytoclastic immune-mediated skin vasculitis, and positive ANA. He had spontaneous improvement in renal function without immunosuppressive therapy. This crescentic GN was not associated with poor renal outcome as AKI resolved with supportive care and treatment of his infection. The AKI was likely multifactorial with co-existing acute tubular necrosis in the setting of Kebsiella sepsis and rhabdomyolysis, and the crescentic GN was felt more likely to be related to the infection rather than having a primary role. This case highlights the importance of viewing crescentic GN in the context of the clinical picture, as it may not always lead to the need of aggressive immune suppression and is not a universally poor prognostic kidney finding. However, these cases do warrant close follow-up as our patient had recurrent RA disease manifestations over the next 2 years that eventually led to his death from severe pulmonary hypertension.

Hepatorenal Syndrome (HRS) is an important condition for clinicians to be aware of in the presence of cirrhosis. In simple terms, HRS is defined as a relative rise in creatinine and relative drop in serum glomerular filtration rate (GFR) alongside renal plasma flow (RPF) in the absence of other competing etiologies of acute kidney injury (AKI) in patients with hepatic cirrhosis. It represents the end stage complication of decompensated cirrhosis in the presence of severe portal hypertension, in the absence of prerenal azotemia, acute tubular necrosis or others. It is a diagnosis of exclusion. The recognition of HRS is of paramount importance for clinicians as it carries a high mortality rate and is an indication for transplantation. Recent advances in understanding the pathophysiology of the disease improved treatment approaches, but the overall prognosis remains poor, with Type I HRS having an average survival under 2 weeks. Generally speaking, AKI and renal failure in cirrhotic patients carry a very high mortality rate, with up to 60% mortality rate for patients with renal failure and cirrhosis and 86.6% of overall mortality rates of patients admitted to the intensive care unit. Of the various etiologies of renal failure in cirrhosis, HRS carries a poor prognosis among cirrhotic patients with acute kidney injury. HRS continues to pose a diagnostic challenge. AKI can be either pre-renal, intrarenal or postrenal. Prerenal causes include hypovolemia, infection, use of vasodilators and functional due to decreased blood flow to the kidney, intra-renal such as glomerulopathy, acute tubular necrosis and post-renal such as obstruction. Patients with cirrhosis are susceptible to developing renal impairment. HRS may be classified as Type 1 or rapidly progressive disease, and Type 2 or slowly progressive disease. There are other types of HRS, but this chapter will focus on Type 1 HRS and Type 2 HRS. HRS is considered a functional etiology of acute kidney injury as there is an apparent lack of nephrological parenchymal damage. It is one several possibilities for acute kidney injury in patients with both acute and chronic liver disease. Acute kidney injury (AKI) is one of the most severe complications that could occur with cirrhosis. Up to 50% of hospitalized patients with cirrhosis can suffer from acute kidney injury, and as mentioned earlier an AKI in the presence of cirrhosis in a hospitalized patient has been associated with nearly a 3.5-fold increase in mortality. The definition of HRS will be discussed in this chapter, but it is characterized specifically as a form of acute kidney injury that occurs in patients with advanced liver cirrhosis which results in a reduction in renal blood flow, unresponsive to fluids this occurs in the setting of portal hypertension and splanchnic vasodilation. This chapter will discuss the incidence of HRS, recognizing HRS, focusing mainly on HRS Type I and Type II, recognizing competing etiologies of renal impairment in cirrhotic patients, and the management HRS.

Background/Aims. Acute kidney injury is a common problem for patients with cirrhosis and is associated with poor survival. We aimed to examine the association between type of acute kidney injury and 90-day mortality.Methods. Prospective cohort study at a major US liver transplant center. A nephrologist’s review of the urinary sediment was used in conjunction with the 2007 Ascites Club Criteria to stratify acute kidney injury into four groups: prerenal azotemia, hepatorenal syndrome, acute tubular necrosis, or other.Results. 120 participants with cirrhosis and acute kidney injury were analyzed. Ninety-day mortality was 14/40 (35%) with prerenal azotemia, 20/35 (57%) with hepatorenal syndrome, 21/36 (58%) with acute tubular necrosis, and 1/9 (11%) with other (p=0.04overall). Mortality was the same in hepatorenal syndrome compared to acute tubular necrosis (p=0.99). Mortality was lower in prerenal azotemia compared to hepatorenal syndrome (p=0.05) and acute tubular necrosis (p=0.04). Ten participants (22%) were reclassified from hepatorenal syndrome to acute tubular necrosis because of granular casts on urinary sediment.Conclusions. Hepatorenal syndrome and acute tubular necrosis result in similar 90-day mortality. Review of urinary sediment may add important diagnostic information to this population. Multicenter studies are needed to validate these findings and better guide management.

Objectives: We investigated the risk factors for contrast-induced acute kidney injury (CIAKI) after coronary angiography (CAG) in patients with acute heart failure (AHF), especially with regard to the volume status. Background: Heart failure is a well-known risk factor for CIAKI after CAG. In HF patients, renal perfusion decreases with systemic congestion. Thus, the standard prevention strategy with isotonic solution infusion may be inappropriate while decongestion may be beneficiary in AHF patients undergoing CAG. Deviation from dry body weight suggests imbalanced volume status. Methods: A total of 199 AHF patients who underwent CAG were eligible for the analysis. Absolute deviation of body weight (
