Clinical analysis of liver dysfunction in pregnant patients with mild SARS CoV-2 infection

Objective: The current study aimed to describe the clinical characteristics of mild SARS-CoV-2 infected pregnant women with abnormal liver function (ALF), explore the association between ALF with maternal and fetal outcomes. Method(s): This retrospective analysis included 87 pregnant patients with mild SARS-CoV-2 infection admitted and treated from December 1, 2022, to 31, 2022 in the department of Obestircs at Beijing Obstetrics and Gynecology Hospital. We evaluated patients for demographic and clinical features, laboratory parameters and pregnancy complications. Result(s): 27 Patients in this cohort had clinical presentations of ALF. Compared with the control group, the peripheral blood platelet (PLT), D-dimer quantitative determination (D-Dimer), lactate dehydrogenase (LDH), total protein (TP), albumin (ALB), indirect bilirubin (DBIL), gamma- glutamyltranspeptidase (GGT) and total bile acid (TBA) showed significantly differences (p<0.05). 12 cases (44.44%) complicated with pregnancy induced hypertension (PIH), 14 cases (51.85%) complicated with intrahepatic cholestasis of pregnancy (ICP), 2 cases (7.4%) complicated with acute fatty liver during pregnancy (AFLP) and 5 cases (14.81%) complicated with postpartum hemorrhage in patients with abnormal LFT were significantly higher than those in the control group (p<0.05). Compared with the control group, the incidence of premature delivery (22.22%) and fetal distress (37.04%) in the experiment group were significantly higher (p<0.05), and the incidence of neonatal asphyxia was not significantly different (p>0.05). Conclusion(s): Pregnant women are generally susceptible to mild SARS-CoV-2 and may induce ALF. ALF is associated with increased risk of mother and infant. The maternal and infant outcomes of those who terminated pregnancy in time are acceptable. Therefore, pregnant women with COVID-19 who received antiviral treatment should be closely monitored for evaluating liver function and relevant indicators. The long-term outcomes in the future are worth to further study.Copyright © 2023

Relationship between COVID-19 and liver diseases: The role of hepatologists in clinical practice.

COVID-19 due to severe acute respiratory syndrome coronavirus 2, which has become a global pandemic, produces elevated liver enzymes, especially in severe cases. The mechanism suggests involvement of an administrated drug, cytokine storm, or hypoxia, etc., as opposed to virus-induced direct damage. If liver enzymes are elevated in COVID-19, we should evaluate for the presence of other liver diseases, and strictly follow-up liver enzyme values. In patients with COVID-19 complicated by chronic liver disease, we will use telemedicine/visits by phone, so as not to interrupt the treatment of the underlying disease, avoid unnecessary outpatient visits, and strive to halt the spread of the infection. Metabolism-associated fatty liver disease, which is often related to obesity, diabetes, and hypertension, may be a risk factor for COVID-19 severity. International academic societies have recommended guidance outlining the evidence to date regarding the management of patients with COVID-19 and liver disorders, and chronic liver disease under the COVID-19 pandemic.Copyright 2020 The Japan Society of Hepatology.

The Intersection of COVID-19 and Metabolic-Associated Fatty Liver Disease: An Overview of the Current Evidence.

The global population is currently experiencing the impact of the SARS-CoV-2 coronavirus, which has caused the Coronavirus Disease 2019 (COVID-19) pandemic. With our profound comprehension of COVID-19, encompassing the involvement sequence of the respiratory tract, gastrointestinal system, and cardiovascular apparatus, the multiorgan symptoms of this infectious disease have been discerned. Metabolic-associated fatty liver disease (MAFLD), formerly known as non-alcoholic fatty liver disease (NAFLD), is a pervasive public health concern intricately linked with metabolic dysregulation and estimated to afflict one-fourth of the global adult population. The burgeoning focus on the association between COVID-19 and MAFLD is justified by the potential role of the latter as a risk factor for both SARS-CoV-2 infection and the subsequent emergence of severe COVID-19 symptoms. Investigations have suggested that changes in both innate and adaptive immune responses among MAFLD patients may play a role in determining the severity of COVID-19. The remarkable similarities observed in the cytokine pathways implicated in both diseases imply the existence of shared mechanisms governing the chronic inflammatory responses characterizing these conditions. The effect of MAFLD on the severity of COVID-19 illness remains uncertain, as indicated by conflicting results in cohort investigations.

Management of patients with liver derangement during the COVID-19 pandemic

COVID-19 pandemic has been affecting the whole world for more than 3 years since late 2019. It is often to encounter COVID-19 patients with abnormal liver function, either in the form of hepatitis, cholestasis or both. The clinical implication of such liver derangement may be variable in different clinical scenarios. With the growing evidence of the clinical significance of such liver derangement, it would be clinically helpful to provide practice recommendations to various common clinical scenarios of liver derangement during COVID-19 pandemic. The Asia-Pacific Working Group for Liver Derangement during the COVID-19 Pandemic was formed to systematically review the literature on specified domains of interest, with special focus on clinical management of patients who have been or are at risk of developing liver derangement during COVID-19 pandemic. This Asia-Pacific position statement reports an in-depth review and a position statement on liver derangement during COVID- 19 pandemic. Ten clinical scenarios covering the use of pharmacological treatment for COVID-19 in case of liver derangement, assessment and management of patients with chronic hepatitis B or C, nonalcoholic fatty liver disease (NAFLD), liver cirrhosis, liver transplantation are discussed. Specifically, some treatments target the patient's dysregulated inflammatory response during COVID-19 infection and may cause hepatitis B reactivation (HBVr) in patients with current or past hepatitis B virus (HBV) infection. Current evidence suggests that current or past HBV infection is not associated with an increased risk of liver injury and severe disease in COVID-19 patients. Among patients who received high-dose corticosteroids, various immunosuppressive monoclonal antibodies and inhibitors of Janus kinase, the risk of HBVr exists, especially among those without antiviral prophylaxis.

Pre-existing chronic liver disease is associated with poor outcome in patients with SARS-CoV2 infection

COVID-19 is characterized by predominant respiratory and gastrointestinal symptoms. Liver enzymes derangement is seen in 15-55% of the patients. Cirrhosis is characterized by immune dysregulation, leading to concerns that these patients may be at increased risk of complications following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Patients with metabolic dysfunction-associated fatty liver (MAFLD) had shown a 4-sixfold increase in severity of COVID-19, and its severity and mortality increased in patients with higher fibrosis scores. Patients with chronic liver disease had shown that cirrhosis is an independent predictor of severity of COVID-19 with increased hospitalization and mortality. An international European registry study included 756 patients with chronic liver disease from 29 countries reports high mortality in patients with cirrhosis (32%). Data of 228 patients collected from 13 Asian countries on patients with CLD, known or newly diagnosed, with confirmed COVID-19 (APCOLIS study) showed that SARSCoV- 2 infection produces acute liver injury in 43% of CLD patients without cirrhosis. Additionally, 20% of compensated cirrhosis patients develop either ACLF or acute decompensation. In decompensated cirrhotics, the liver injury was progressive in 57% of patients, with 43% mortality. Patients with CLD and associated diabetes and obesity had a worse outcome. Liver related complications were seen in nearly half of the decompensated cirrhotics, which were of greater severity and with higher mortality. Increase in Child Turcotte Pugh (CTP) score and model for end-stage liver disease (MELD) score increases the mortality in these patients. In a subsequent study of 532 patients from 17 Asian countries was obtained with 121 cases of cirrhosis. An APCOLIS risk score was developed, which included presence of comorbidity, low platelet count, AKI, HE and respiratory failure predicts poor outcome and an APCOLIS score of 34 gave a sensitivity and specificity of 79.3%, PPV of 54.8% and NPV of 92.4% and predicted higher mortality (54.8% vs 7.6%, OR = 14.3 [95 CI 5.3-41.2], p<0.001) in cirrhosis patients with Covid-19. The APCOLIS score is helpful in triaging and prognostication of cirrhotics with Coivd-19. The impact of COVID-19 on patients with cirrhosis due to non-alcoholic fatty liver disease (NASH-CLD) was separately studied in 177 NASH-CLD patients. Obese patients with diabetes and hypertension had a higher prevalence of symptomatic COVID. Presence of diabetes [HR 2.27], fraility [HR 2.68], leucocyte counts [HR 1.69] and COVID-19 were independent predictors of worsening liver functions in patients with NASH-CLD. Severity of Covid in Cirrhosis could also be assessed by measuring ICAM1 the Intercellular Adhesion Molecule, an indicator of Endothelial Injury Marker. in Cirrhosis with Covid 19 Immunosuppression should be reduced prophylactically in patients with autoimmune liver disease and post-transplantation with no COVID-19. Hydroxychloroquine and remdesivir are found to be safe in limited studies in a patient with cirrhosis and COVID-19. And is safe in cirrhosis patients. However, flare of AIH has been reported in AIH patients. For hepatologists, cirrhosis with COVID-19 is a pertinent issue as the present pandemic cause severe disease in patients with chronic liver disease leading to more hospitalization and decompensation.

New Onset Diabetes and Acute Pancreatitis- A Sequela of Long COVID?

Introduction: The association between worse COVID-19 outcomes and diabetes has been well-established in the literature. However, with more cases of new-onset diabetes and pancreatitis being reported with or after COVID-19 infection, it poses the question if there is a causal relationship between them. Case Description: 31 y/o female with COVID-19 infection 4-6 weeks ago with moderate symptoms (not requiring hospital admission or monoclonal ab), presented to ED with bandlike epigastric pain radiating to back, which is worsened with food, associated with nausea, vomiting, polyuria, and fatigue. Workup showed lipase 232, AST 180, ALT 256. Blood glucose was 281 and HbA1c was 12. CT A/P showed post cholecystectomy status, normal pancreas with mesenteric adenitis. MRCP showed hepatic steatosis with trace fluid around the pancreas s/o inflammation, and no evidence of choledocholithiasis or biliary dilatation. She denied alcohol use and autoimmune workup for pancreatitis was unremarkable. Islet cell antibodies were negative. The patient improved with fluid resuscitation and was discharged home on insulin with plans to transition to oral agents outpatient. Discussion(s): Long COVID is defined as a range of conditions or symptoms in patients recovering from COVID-19, lasting beyond 4 weeks after infection. A retrospective cohort study showed increased new-onset diabetes incidence in patients after COVID-19. This was redemonstrated in a systematic review and meta-analysis that showed a 14.4% increased proportion of new diagnoses of diabetes in patients hospitalized with COVID-19. Possible pathophysiology that have been attributed to this include undiagnosed pre-existing diabetes, hyperglycemia secondary to acute illness and stress from increased inflammatory markers during the cytokine storm, the effect of viral infections on the pancreas, and concurrent steroid use in patients with severe respiratory disease. The binding of SARS-CoV-2 to ACE2 receptors is thought to the other mechanism by which COVID can cause pancreatitis and hyperglycemia. Study showed increased lipase and amylase levels in patients with COVID and the increase in serum levels was proportional to the severity of the disease. Patients who died due to COVID-19 were also found to have degeneration of the islet cells. While, several studies have showed new onset diabetes and pancreatitis during an active COVID infections, we need larger cohort studies to comment on its true association or causation, especially in patients with long COVID symptoms. As more cases of new onset diabetes and pancreatitis with COVID-19 are being reported, there may be a need for more frequent blood sugar monitoring during the recovery phase of COVID-19.Copyright © 2023

Chest CT opportunistic biomarkers for phenotyping high-risk COVID-19 patients: a retrospective multicentre study.

OBJECTIVE: To assess the value of opportunistic biomarkers derived from chest CT performed at hospital admission of COVID-19 patients for the phenotypization of high-risk patients. METHODS: In this multicentre retrospective study, 1845 consecutive COVID-19 patients with chest CT performed within 72 h from hospital admission were analysed. Clinical and outcome data were collected by each center 30 and 80 days after hospital admission. Patients with unknown outcomes were excluded. Chest CT was analysed in a single core lab and behind pneumonia CT scores were extracted opportunistic data about atherosclerotic profile (calcium score according to Agatston method), liver steatosis (≤ 40 HU), myosteatosis (paraspinal muscle F < 31.3 HU, M < 37.5 HU), and osteoporosis (D12 bone attenuation < 134 HU). Differences according to treatment and outcome were assessed with ANOVA. Prediction models were obtained using multivariate binary logistic regression and their AUCs were compared with the DeLong test. RESULTS: The final cohort included 1669 patients (age 67.5 [58.5-77.4] yo) mainly men 1105/1669, 66.2%) and with reduced oxygen saturation (92% [88-95%]). Pneumonia severity, high Agatston score, myosteatosis, liver steatosis, and osteoporosis derived from CT were more prevalent in patients with more aggressive treatment, access to ICU, and in-hospital death (always p < 0.05). A multivariable model including clinical and CT variables improved the capability to predict non-critical pneumonia compared to a model including only clinical variables (AUC 0.801 vs 0.789; p = 0.0198) to predict patient death (AUC 0.815 vs 0.800; p = 0.001). CONCLUSION: Opportunistic biomarkers derived from chest CT can improve the characterization of COVID-19 high-risk patients. CLINICAL RELEVANCE STATEMENT: In COVID-19 patients, opportunistic biomarkers of cardiometabolic risk extracted from chest CT improve patient risk stratification. KEY POINTS: • In COVID-19 patients, several information about patient comorbidities can be quantitatively extracted from chest CT, resulting associated with the severity of oxygen treatment, access to ICU, and death. • A prediction model based on multiparametric opportunistic biomarkers derived from chest CT resulted superior to a model including only clinical variables in a large cohort of 1669 patients suffering from SARS- CoV2 infection. • Opportunistic biomarkers of cardiometabolic comorbidities derived from chest CT may improve COVID-19 patients' risk stratification also in absence of detailed clinical data and laboratory tests identifying subclinical and previously unknown conditions.

Liver injury in COVID-19 patients with non-alcoholic fatty liver disease: an update.

The coronavirus disease 2019 (COVID-19) pandemic has revolutionized the priorities of the medical society worldwide. Although most patients infected with SARS-CoV-2 exhibit respiratory symptoms, other organs may also be involved, including the liver, often resulting in liver injury. Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in the world, and its prevalence is expected to increase together with the epidemics of type 2 diabetes and obesity. Data about liver injury during COVID-19 are numerous, while overviews of this infection in patients with NAFLD, both in terms of respiratory and liver, are emerging. In this review, we summarise the current research focusing on COVID-19 in NAFLD patients and discuss the association between liver injury in COVID-19 subjects and non-alcoholic fatty liver disease.

Solid organ graft-versus-host disease in a recipient of a COVID-19 positive liver graft

A 66-year-old male with end-stage liver disease (ESLD) secondary to non-alcoholic fatty liver disease (NAFLD), complicated by hepatocellular carcinoma (HCC), underwent deceased donor liver transplantation from a Coronavirus disease 2019 (COVID-19) positive donor. He presented a month later with fever, diarrhea and pancytopenia which led to hospitalization. The hospital course was notable for respiratory failure, attributed to invasive aspergillosis, as well as a diffuse rash. A bone marrow biopsy revealed hypocellular marrow without specific findings. In the following days, laboratory parameters raised concern for secondary hemophagocytic lymphohistiocytosis (HLH). Clinical concern also grew for solid organ transplant graft-versus-host-disease (SOT-GVHD) based on repeat marrow biopsy with elevated donor-derived CD3+ T cells on chimerism. After, a multidisciplinary discussion, the patient was started on ruxolitinib, in addition to high dose steroids, to address both SOT-GVHD and secondary HLH. Patient developed symptoms concerning for hemorrhagic stroke and was transitioned to comfort care. Although GVHD has been studied extensively in hematopoietic stem cell transplant (HSCT) patients, it is a rare entity in SOT with a lack of guidelines for management. Additionally, whether COVID-19 may play a role in development of SOT-GVDH has not been explored.Copyright © 2023 The Authors

Hyperammonemia is a risk factor for poor outcomes in patients with COVID-19.

Objective. We analyzed clinical features and laboratory markers of COVID-19 patients according to favorable outcomes versus fatal outcomes. Material and methods. The medical history of 80 patients was analyzed: 51 patients with favorable outcomes were included in group 1, 29 patients with a fatal outcome were included in group 2. Demographic data, duration of the disease, comorbid-ities, laboratory markers, and results of the instrumental studies were included. The ammonia level in the peripheral blood was de-termined by the express method using a PocketChem BA 4140 photometric portable analyzer. Results. Patients in group 2 were older (68+/-11 years) had hypertension stage 3 with high cardiovascular risk;every third had a history of myocardial infarction. At admission, patients from group 2 were most likely with febrile fever and high levels of inflammatory markers - predictors of a cytokine release syndrome. In addition, 71% of patients at admission had elevated ammonia levels. Hyperammonemia correlated with high ferritin levels, leukopenia, non-alcoholic fatty liver disease in patients, and lethal outcomes. Conclusions. The risks of poor COVID-19 outcomes are higher in comorbid patients of the older age group. Hyperammonemia may be one of the predictors of poor COVID-19 outcomes.Copyright © 2022, Media Sphera Publishing Group. All rights reserved.

Analysis on occurrence and risk factors of drug-induced liver injury in patients with novel coronavirus pneumonia.

Objective: To analyze the occurrence and risk factors of drug-induced liver injury (DILI) in patients with novel coronavirus pneumonia (COVID-19). Method(s): The medical records of patients with COVID-19 who were discharged from the First Hospital of Changsha from January 15 to March 7, 2020 were collected and the patients were divided into the DILI group and the non-DILI group based on DILI diagnostic criteria. Basic information of patients in the 2 groups including gender, age, underlying diseases, classification of COVID-19, liver function test results on admission and after medication, drug use, time to DILI onset after medication, and treatments and outcomes of DILI were recorded and compared. The incidence of DILI in patients with COVID-19 was calculated, and the factors whose P<0.05 in inter-group comparison were included in the multivariate logistic regression analysis to calculate the odds ratio (OR) and95% confidence interval (CI). Result(s): A total of 203 discharged patients with COVID-19 met the inclusion criteria. Of them, 36 patients developed DILI, the incidence was 17.73%. Between the DILI group and the non-DILI group (167 patients), the differences were statistically significant in gender distribution, proportion of patients with underlying diseases such as hypertension, fatty liver, and cholelithiasis, clinical classification of COVID-19, and the kinds of drug use (P<0.05 for all), but not statistically significant in levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBil) on admission (P>0.05 for all). The levels of ALT and AST in patients in the DILI group after medication were higher than those before medication, and the differences were statistically significant (P<0.001 for all). The median time for time to DILI onset after medication was 8 (6, 11) days and none of the patients had obvious clinical signs and symptoms. After the occurrence of DILI, 16 patients stopped the suspicious drugs and received liver-protective treatments, 6 patients only stopped the suspicious drug without additional treatments, and 14 patients received liver-protective treatments without drug withdrawal. Among the 36 patients in the DILI group, liver function were improved in 34 patients but did not returned to normal in 2 patients when they were discharged from the hospital. Multivariate logistic regression analysis showed that male (OR=3.939, 95%CI: 1.426-10.883, P=0.008), being severe and critical in clinical classification (OR=6.433, 95%CI: 2.411-17.162, P<0.001), fatty liver (OR=3.815, 95%CI: 1.298-11.215, P=0.015), cholelithiasis (OR=16.347, 95%CI: 1.267-210.990, P=0.032), and the kinds of drug use >8 (OR=10.181, 95%CI: 3.606-28.744, P<0.001) were the independent risk factors of DILI in patients with COVID-19. Conclusion(s): The incidence of DILI in COVID-19 patients discharged from the First Hospital of Changsha is 17.73%. Male, being severe and critical in clinical classification of COVID-19, fatty liver, cholelithiasis, and the kinds of drug use >8 are the independent risk factors for DILI patients with COVID-19.Copyright © 2020 by the Chinese Medical Association.

COVID-19 and MAFLD/NAFLD: An updated review.

The COVID-19 pandemic is ongoing and places a substantial burden on healthcare systems worldwide. As we further shed light on different disease characteristics, we identify more and more groups of people at higher risk of poor COVID-19 outcomes. Metabolic-associated fatty liver disease (MAFLD) (previously non-alcoholic fatty liver disease or NAFLD) is a common metabolic disorder characterized by fat accumulation and liver fibrosis. Given its close correlation with metabolic syndrome, an established risk factor for severe COVID-19, it is necessary to investigate its interplay with the novel coronavirus. In this study, we review the available data on COVID-19 prognosis, treatment and prevention options in patients with MAFLD, and the effect that the disease and the pandemic have on MAFLD care. Furthermore, we point out the gaps in the current literature to accentuate the work that needs to be done to improve MAFLD care during the pandemic and beyond.

Nonalcoholic fatty liver disease and non-liver comorbidities.

Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease characterized by excess fat accumulation in the liver. It is closely associated with metabolic syndrome, and patients with NAFLD often have comorbidities such as obesity, type 2 diabetes mellitus, and dyslipidemia. In addition to liver-related complications, NAFLD has been associated with a range of non-liver comorbidities, including cardiovascular disease, chronic kidney disease, and sleep apnea. Cardiovascular disease is the most common cause of mortality in patients with NAFLD, and patients with NAFLD have a higher risk of developing cardiovascular disease than the general population. Chronic kidney disease is also more common in patients with NAFLD, and the severity of NAFLD is associated with a higher risk of developing chronic kidney disease. Sleep apnea, a disorder characterized by breathing interruptions during sleep, is also more common in patients with NAFLD and is associated with the severity of NAFLD. The presence of non-liver comorbidities in patients with NAFLD has important implications for the management of this disease. Treatment of comorbidities such as obesity, type 2 diabetes mellitus, and dyslipidemia may improve liver-related outcomes in patients with NAFLD. Moreover, treatment of non-liver comorbidities may also improve overall health outcomes in patients with NAFLD. Therefore, clinicians should be aware of the potential for non-liver comorbidities in patients with NAFLD and should consider the management of these comorbidities as part of the overall management of this disease.

Obstetric Disorders and Critical Illness.

In this article, we discuss some of the more common obstetric-related conditions that can lead to critical illness and require management in an ICU. These include the hypertensive disorders of pregnancy, postpartum hemorrhage, hemolysis, elevated liver enzymes, and low platelet syndrome, acute fatty liver of pregnancy, amniotic fluid embolism, and peripartum cardiomyopathy. We also discuss pulmonary embolism and Covid-19. Despite not being specific to obstetric patients, pulmonary embolism is a common, life-threatening diagnosis in pregnancy with particular risks and management aspects. Covid-19 does not seem to occur with higher frequency in pregnant women, but it leads to higher rates of ICU admissions and mechanical ventilation in pregnant women than in their nonpregnant peers. Its prevalence during our current global pandemic makes it important to discuss in this article. We provide a basis for critical care physicians to be engaged in informed conversations and management in a multidisciplinary manner with other relevant providers in the care of critically ill pregnant and postpartum women.

Changing Trends of Pregnancy Related Acute Kidney Injury - a Single Centre Prospective Observational Study from Southern India

Introduction: Pregnancy-related acute kidney injury (PR-AKI) in India is largely showing a declining trend due to improved and accessible obstetric care. Nevertheless, PR-AKI continues to cause significant maternal and fetal morbidity and mortality. This study was taken up with the intention to study the incidence and clinical spectrum of AKI in pregnancy in recent times and assess maternal and neonatal outcomes Methods: All pregnant women admitted in the Department of Obstetrics and Gynecology at St John's Medical College Hospital, Bengaluru between January 2018 to June 2020 were screened for AKI with the following criteria 1. Increase in serum creatinine to >0.8mg/dL and/or a sudden increase in serum creatinine by more than 50% when prior renal function was normal. 2. Oligo-anuria 3. Need for renal replacement therapy Women with preexisting CKD were excluded. Patient's clinical and laboratory details recorded. Dialysis support was provided if indicated. The clinical profile and renal outcome of the mother and fetal outcome was assessed at the time of discharge. Mothers' were also followed up at the end of 3 months of postpartum period. Recovery was categorized as Complete recovery- normal serum creatinine (<0.8 mg/dL) or a previously known baseline and no proteinuria /hypertension at the end of 3 months Partial recovery- renal function improved but serum creatinine did not return to normal range and patient was dialysis independent. No recovery- patient continued to require dialysis at the end of 3months. Result(s): Of the 2650 deliveries in the study period 42 women (Mean age 26.9 +/-3.6 years) were diagnosed AKI during pregnancy (1.58%). Baseline characteristics and outcomes are depicted in table 1. Majority of women (n=37) were referred from peripheral hospitals. Hypertension and decreased fetal movements were the common reasons for referral. Third trimester was the most common time of presentation (76.1%). Severe Preeclampsia and HELLP syndrome was the leading cause of AKI (59.5%).ATN secondary to obstetric complications, sepsis and hemolytic uremic syndrome were the other causes. One case each of cortical necrosis, acute fatty liver of pregnancy and COVID 19 associated AKI was seen. Mean duration of hospital stay was 12.1+/-6.9 days. More than one third patients' required ICU stay (35.7%).12 patients (28.5%) required renal replacement therapy. Of them, 3 were dialysis dependent at the end of 3 months and 4 had partial renal recovery. 3 patients expired during hospital stay. Fetal survival was 69.04%.13 babies' required NICU care (44.8%). Neonatal outcomes are summarized in table 2. Close to one third of the pregnancies with AKI were associated with intrauterine fetal demise (28.5%). Low birth weight and prematurity were the common reasons for NICU admission with mean NICU stay of 8.2 +/-2.3 days [Formula presented] [Formula presented] Conclusion(s): Severe preeclampsia was the most common cause of AKI in our study. PR-AKI continues to be a significant problem in the peripheries of developing countries where availability of health care facilities is meager, with late referral to tertiary care centers. One third of the patients required ICU stay & dialytic support. Women who required dialysis had poorer renal prognosis. There was 30% fetal loss seen in PR-AKI and also a higher incidence of low birth weight and prematurity. No conflict of interestCopyright © 2023
