Fulltext A fatal case of metformin and gliclazide poisoning and its management

Low, Qin Jian, Chew, Soo Foong

Borneo Journal of Medical Sciences, 2017;11(3):35-40.
MyJurnal

Both metformin and gliclazide have been used extensively in the management of type II diabetes mellitus. Metformin and gliclazide overdose can lead to severe hypoglycaemia refractory to intravenous (IV) dextrose rescue therapy. A 21-year-old man complained of vomiting and felt dizzy after four hours of taking 70 tablets of Metformin 500 mg and 40 tablets of Gliclazide 80 mg. He had major depressive disorder and wanted to commit suicide. He was given IV Dextrose 50% 50 cc immediately. Octreotide had been used successfully to reverse the refractory hypoglycaemia caused by gliclazide overdose. Unfortunately, he developed severe lactic acidosis with acute kidney injury. Dialysis had been done by continuous venovenous haemodiafiltrationa and intravenous sodium bicarbonate 8.4% infusion was given. However, the patient succumbed due to the severe lactic acidosis and kidney failure despite of urgent dialysis. Octreotide infusion helps in preventing refractory hypoglycaemia secondary to sulfonylurea overdose by inhibit calcium-mediated insulin release. Metformin overdose causes severe lactic acidosis due to conversion of glucose to lactate. Sodium bicarbonate therapy in metformin induced lactic acidosis is also controversial. Though sulfonylurea and metformin are the most commonly-prescribed anti-hypoglycaemic agents, thus during prescribing everyone has to be careful about the overdoses and side effects of these drugs.

Association of ethnicity and acute kidney injury after cardiac surgery in a South East Asian population

Chew ST, Mar WM, Ti LK

Br J Anaesth, 2013 Mar;110(3):397-401.
PMID: 23171723 DOI: 10.1093/bja/aes415

BACKGROUND: Postoperative acute kidney injury (AKI) is a frequent and serious complication after cardiac surgery. Clinical factors alone have failed to accurately predict the incidence of AKI after cardiac surgery. Ethnicity has been shown to be a predictor of AKI in the Western population. We tested the hypothesis that ethnicity is an independent predictor of AKI in patients undergoing cardiac surgery in a South East Asian population.
METHODS: A total of 1756 consecutive patients undergoing cardiac surgery were prospectively recruited. Among them, data of 1639 patients met the criteria for analysis. There were 1182 Chinese, 195 Indian, and 262 Malay patients. The main outcome was postoperative AKI, defined as a 25% or greater increase in preoperative to a maximum postoperative serum creatinine level within 3 days after surgery.
RESULTS: Five hundred and seventy-nine patients (35.3%) developed AKI after cardiac surgery. Ethnicity was shown to be an independent predictor of AKI after cardiac surgery with Indians and Malays having a higher risk of developing AKI when compared with Chinese patients (odds ratio: Indian vs Chinese 1.44, Malay vs Chinese 1.51).
CONCLUSIONS: Indians and Malays have a higher risk of developing AKI after cardiac surgery than Chinese in a South East Asian population. Ethnicity was shown to be an independent predictor of AKI after cardiac surgery.

PMID: 33567737 DOI: 10.3390/cancers13040688

Several randomized controlled trials (RCTs) evaluated the afatinib efficacy in patients with advanced non-small cell lung cancer (NSCLC) and recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC). This review systemically outlined and meta-analyzed the afatinib efficacy in NSCLC and R/M HNSCC in terms of overall survival (OS) and progression-free survival (PFS) endpoints. Records were retrieved from PubMed, Web of Science, and ScienceDirect from 2011 to 2020. Eight afatinib RCTs were included and assessed for the risk of bias. In meta-analysis, overall pooled effect size (ES) of OS in afatinib group (AG) significantly improved in all RCTs and NSCLC-RCTs [hazard ratios (HRs): 0.89 (95% CI: 0.81-0.98, p = 0.02); I2 = 0%, p = 0.71/ 0.86 (95% CI: 0.76-0.97; p = 0.02); I2 = 0%, p = 0.50, respectively]. ES of PFS in AG significantly improved in all RCTs, NSCLC-RCTs, and HNSCC-RCTs [HRs: 0.75 (95% CI: 0.68-0.83; p < 0.00001); I2 = 26%, p = 0.24; 0.75 (95% CI: 0.66-0.84; p < 0.00001); I2 = 47%, p = 0.15/0.76 (95% CI: 0.65-88; p = 0.0004); I2 = 34%, p = 0.0004, respectively]. From a clinical viewpoint of severity, interstitial lung disease, dyspnea, pneumonia, acute renal failure, and renal injury were rarely incident adverse events in the afatinib group. In conclusion, first- and second-line afatinib monotherapy improved the survival of patients with NSCLC, while second-line afatinib monotherapy could be promising for R/M HNSCC. The prospective protocol is in PROSPERO (ID = CRD42020204547).

Fulltext A Rare Cause of Acute Kidney Injury: Primary Renal Lymphoma in a Patient with Human Immunodeficiency Virus

Mustafar R, Kamaruzaman L, Chien BH, Yahaya A, Mohd Nasir N, Mohd R, et al.

Case Rep Med, 2018;2018:8425985.
PMID: 30186328 DOI: 10.1155/2018/8425985

We reported a case of primary renal lymphoma (PRL) presented with non-oliguric acute kidney injury and bilateral kidney infiltrates in an individual with human immunodeficiency virus (HIV) disease. Acute kidney injury secondary to lymphoma infiltrates is very rare (less than 1% of hematological malignancy). A 37-year-old gentleman with underlying human immunodeficiency virus (HIV) disease was on combined antiretroviral therapy since diagnosis. He presented to our center with uremic symptoms and gross hematuria. Clinically, bilateral kidneys massively enlarged and were ballotable. Blood investigations showed hemoglobin of 3.7 g/L, urea of 65.6 mmol/L, and serum creatinine of 1630 µmol/L with hyperkalemia and metabolic acidosis. An urgent hemodialysis was initiated, and he was dependent on regular hemodialysis subsequently. Computed tomography renal scan showed diffuse nonenhancing hypodense lesion in both renal parenchyma. Diagnosis of diffuse large B cell lymphoma with germinal center type, CD20 positive, and proliferative index 95% was confirmed via renal biopsy, and there was no bone marrow infiltrates. Unfortunately, the patient succumbs prior to initiation of chemotherapy.

Fulltext Ischemic Stroke in a Young Patient with Nephrotic Syndrome and Antiphospholipid Syndrome

Neoh KK, Tang ASN, Looi I, Anita BM

Case Rep Nephrol, 2020;2020:8828864.
PMID: 33294240 DOI: 10.1155/2020/8828864

We report a case of a 21-year-old man with underlying nephrotic syndrome (NS) secondary to minimal change disease, who developed an ischemic stroke with left hemiparesis. He received intravenous thrombolysis followed by a mechanical thrombectomy. After mechanical thrombectomy, he developed acute kidney injury which subsequently required haemodialysis. Further workup revealed that he had concomitant antiphospholipid syndrome (APS) and NS. He was started on vitamin K antagonist anticoagulant. This case report illustrates the importance of workup in identifying causes of ischemic stroke in a young patient.

Fulltext Age-Related Clinical Spectrum of Plasmodium knowlesi Malaria and Predictors of Severity

Grigg MJ, William T, Barber BE, Rajahram GS, Menon J, Schimann E, et al.

Clin Infect Dis, 2018 Jul 18;67(3):350-359.
PMID: 29873683 DOI: 10.1093/cid/ciy065

BACKGROUND: Plasmodium knowlesi is increasingly reported in Southeast Asia, but prospective studies of its clinical spectrum in children and comparison with autochthonous human-only Plasmodium species are lacking.
METHODS: Over 3.5 years, we prospectively assessed patients of any age with molecularly-confirmed Plasmodium monoinfection presenting to 3 district hospitals in Sabah, Malaysia.
RESULTS: Of 481 knowlesi, 172 vivax, and 96 falciparum malaria cases enrolled, 44 (9%), 71 (41%), and 31 (32%) children aged ≤12 years. Median parasitemia was lower in knowlesi malaria (2480/μL [interquartile range, 538-8481/μL]) than in falciparum (9600/μL; P < .001) and vivax malaria. In P. knowlesi, World Health Organization-defined anemia was present in 82% (95% confidence interval [CI], 67%-92%) of children vs 36% (95% CI, 31%-41%) of adults. Severe knowlesi malaria occurred in 6.4% (95% CI, 3.9%-8.3%) of adults but not in children; the commenst severity criterion was acute kideny injury. No patient had coma. Age, parasitemia, schizont proportion, abdominal pain, and dyspnea were independently associated with severe knowlesi malaria, with parasitemia >15000/μL the best predictor (adjusted odds ratio, 16.1; negative predictive value, 98.5%; P < .001). Two knowlesi-related adult deaths occurred (fatality rate: 4.2/1000 adults).
CONCLUSIONS: Age distribution and parasitemia differed markedly in knowlesi malaria compared to human-only species, with both uncomplicated and severe disease occurring at low parasitemia. Severe knowlesi malaria occurred only in adults; however, anemia was more common in children despite lower parasitemia. Parasitemia independently predicted knowlesi disease severity: Intravenous artesunate is warranted initially for those with parasitemia >15000/μL.

Acute renal failure after a holiday in the tropics

Guron G, Holmdahl J, Dotevall L

Clin. Nephrol., 2006 Dec;66(6):468-71.
PMID: 17176921 DOI: 10.5414/cnp66468

A 20-year-old, previously healthy woman, presented with high fever, headache and myalgia 3 days after her return from a holiday in Southeast Asia. Laboratory data on admission demonstrated a pronounced increase in plasma creatinine, marked thrombocytopenia and moderately elevated liver aminotransferases. After having ruled out malaria, dengue fever was primarily suspected and supportive intravenous fluid therapy was initiated. Still, 1 day after admission, platelet counts dropped even further and she became anuric although she did not appear hypovolemic. On day 2 after admission, urine production commenced spontaneously and the patient slowly recovered. All laboratory test results had returned to normal approximately 2 months later. Serological analysis for dengue fever was negative. It turned out that the patient had been trekking in the jungle while in Thailand and we, therefore, analyzed serology for Leptospira spirochetes which was clearly positive. The patient was diagnosed with leptospirosis which is a serious condition associated with a high mortality when complicated by acute renal failure. Differential diagnoses in patients with acute renal failure and tropical infections are reviewed. The importance of early recognition of leptospirosis, and prompt treatment with antibiotics in suspected cases, is emphasized.

Fulltext The clinical utility window for acute kidney injury biomarkers in the critically ill

Ralib AM, Pickering JW, Shaw GM, Than MP, George PM, Endre ZH

Crit Care, 2014;18(6):601.
PMID: 25366893 DOI: 10.1186/s13054-014-0601-2

INTRODUCTION: Acute Kidney Injury (AKI) biomarker utility depends on sample timing after the onset of renal injury. We compared biomarker performance on arrival in the emergency department (ED) with subsequent performance in the intensive care unit (ICU).
METHODS: Urinary and plasma Neutrophil Gelatinase-Associated Lipocalin (NGAL), and urinary Cystatin C (CysC), alkaline phosphatase, γ-Glutamyl Transpeptidase (GGT), α- and π-Glutathione S-Transferase (GST), and albumin were measured on ED presentation, and at 0, 4, 8, and 16 hours, and days 2, 4 and 7 in the ICU in patients after cardiac arrest, sustained or profound hypotension or ruptured abdominal aortic aneurysm. AKI was defined as plasma creatinine increase ≥ 26.5 μmol/l within 48 hours or ≥ 50% within 7 days.
RESULTS: n total, 45 of 77 patients developed AKI. Most AKI patients had elevated urinary NGAL, and plasma NGAL and CysC in the period 6 to 24 hours post presentation. Biomarker performance in the ICU was similar or better than when measured earlier in the ED. Plasma NGAL diagnosed AKI at all sampling times, urinary NGAL, plasma and urinary CysC up to 48 hours, GGT 4 to 12 hours, and π-GST 8 to 12 hours post insult. Thirty-one patients died or required dialysis. Peak 24-hour urinary NGAL and albumin independently predicted 30-day mortality and dialysis; odds ratios 2.87 (1.32 to 6.26), and 2.72 (1.14 to 6.48), respectively. Urinary NGAL improved risk prediction by 11% (IDI event of 0.06 (0.002 to 0.19) and IDI non-event of 0.04 (0.002 to 0.12)).
CONCLUSION: Early measurement in the ED has utility, but not better AKI diagnostic performance than later ICU measurement. Plasma NGAL diagnosed AKI at all time points. Urinary NGAL best predicted mortality or dialysis compared to other biomarkers.

A Double-Blind Randomized Controlled Trial of High Cutoff Versus Standard Hemofiltration in Critically Ill Patients With Acute Kidney Injury

Atan R, Peck L, Prowle J, Licari E, Eastwood GM, Storr M, et al.

Crit Care Med, 2018 10;46(10):e988-e994.
PMID: 30074491 DOI: 10.1097/CCM.0000000000003350

OBJECTIVES: In critically ill patients with acute kidney injury receiving vasopressors, high cytokine levels may sustain the shock state. High cutoff hemofiltration achieves greater cytokine removal in ex vivo and in animal models and may reduce the duration of shock but may also increase albumin losses.
DESIGN: This was a single-center double-blind randomized controlled trial comparing continuous venovenous hemofiltration-high cutoff to continuous venovenous hemofiltration-standard.
SETTING: Tertiary care hospital in Australia.
PATIENTS: Vasopressor-dependent patients in acute kidney injury who were admitted to the ICU.
INTERVENTIONS: Norepinephrine-free time were calculated in critically ill vasopressor-dependent patients in acute kidney injury, randomized to either continuous venovenous hemofiltration-high cutoff or continuous venovenous hemofiltration-standard.
MEASUREMENT AND MAIN RESULTS: A total of 76 patients were randomized with the following characteristics (continuous venovenous hemofiltration-high cutoff vs continuous venovenous hemofiltration-standard); median age of 65 versus 70 year, percentage of males 47% versus 68%, and median Acute Physiology and Chronic Health Evaluation scores of 25 versus 23.5. The median hours of norepinephrine-free time at day 7 were 32 (0-110.8) for continuous venovenous hemofiltration-high cutoff and 56 hours (0-109.3 hr) (p = 0.520) for continuous venovenous hemofiltration-standard. Inhospital mortality was 55.6% with continuous venovenous hemofiltration-high cutoff versus 34.2% with continuous venovenous hemofiltration-standard (adjusted odds ratio, 2.49; 95% CI, 0.81-7.66; p = 0.191). There was no significant difference in time to cessation of norepinephrine (p = 0.358), time to cessation of hemofiltration (p = 0.563), and filter life (p = 0.21). Serum albumin levels (p = 0.192) were similar and the median dose of IV albumin given was 90 grams (20-212 g) for continuous venovenous hemofiltration-high cutoff and 80 grams (15-132 g) for continuous venovenous hemofiltration-standard (p = 0.252).
CONCLUSIONS: In critically ill patients with acute kidney injury, continuous venovenous hemofiltration-high cutoff did not reduce the duration of vasopressor support or mortality or change albumin levels compared with continuous venovenous hemofiltration-standard.

Successful treatment of acute kidney injury secondary to haeme nephropathy in paroxysmal nocturnal haemoglobinuria with alkaline diuresis

Sakthiswary R, Das S, Fadilah SA

EXCLI J, 2012;11:198-203.
PMID: 27298607

Paroxysmal nocturnal haemoglobinuria (PNH) also known as 'Marchiafava Micheli syndrome' is a rare condition which can lead to both acute and chronic forms of renal failure through renal tubular haemosiderin deposition. A 45-year-old lady with underlying PNH, presented with complaints of fever, productive cough followed by dark coloured urine. Investigations revealed pancytopenia with a markedly raised creatinine from her baseline (from 65 mmol/L to 385 mmol/L) consistent with acute kidney injury (AKI). Renal biopsy confirmed the diagnosis of haeme nephropathy. The renal impairment improved rapidly and normalised over a period of 5 days with alkaline diuresis (AD). The patient did not require haemodialysis unlike most other reported cases of AKI secondary to haeme nephropathy in PNH. This is the second reported case of AKI in PNH which was successfully treated with AD alone emphasizing the role of AD as a promising therapeutic strategy in this condition.

Renal effects of an emergency department chloride-restrictive intravenous fluid strategy in patients admitted to hospital for more than 48 hours

Yunos NM, Bellomo R, Taylor DM, Judkins S, Kerr F, Sutcliffe H, et al.

Emerg Med Australas, 2017 Dec;29(6):643-649.
PMID: 28597505 DOI: 10.1111/1742-6723.12821

OBJECTIVE: Patients commonly receive i.v. fluids in the ED. It is still unclear whether the choice of i.v. fluids in this setting influences renal or patient outcomes. We aimed to assess the effects of restricting i.v. chloride administration in the ED on the incidence of acute kidney injury (AKI).
METHODS: We conducted a before-and-after trial with 5008 consecutive ED-treated hospital admissions in the control period and 5146 consecutive admissions in the intervention period. During the control period (18 February 2008 to 17 August 2008), patients received standard i.v. fluids. During the intervention period (18 February 2009 to 17 August 2009), we restricted all chloride-rich fluids. We used the Kidney Disease: Improving Global Outcomes (KDIGO) staging to define AKI.
RESULTS: Stage 3 of KDIGO-defined AKI decreased from 54 (1.1%; 95% confidence interval [CI] 0.8-1.4) to 30 (0.6%; 95% CI 0.4-0.8) (P = 0.006). The rate of renal replacement therapy did not change, from 13 (0.3%; 95% CI 0.2-0.4) to 8 (0.2%; 95% CI 0.1-0.3) (P = 0.25). After adjustment for relevant covariates, liberal chloride therapy remained associated with a greater risk of KDIGO stage 3 (hazard ratio 1.82; 95% CI 1.13-2.95; P = 0.01). On sensitivity assessment after removing repeat admissions, KDIGO stage 3 remained significantly lower in the intervention period compared with the control period (P = 0.01).
CONCLUSION: In a before-and-after trial, a chloride-restrictive strategy in an ED was associated with a significant decrease in the incidence of stage 3 of KDIGO-defined AKI.

Fulltext Severe Plasmodium knowlesi malaria in a tertiary care hospital, Sabah, Malaysia

William T, Menon J, Rajahram G, Chan L, Ma G, Donaldson S, et al.

Emerg Infect Dis, 2011 Jul;17(7):1248-55.
PMID: 21762579 DOI: 10.3201/eid1707.101017

The simian parasite Plasmodium knowlesi causes severe human malaria; the optimal treatment remains unknown. We describe the clinical features, disease spectrum, and response to antimalarial chemotherapy, including artemether-lumefantrine and artesunate, in patients with P. knowlesi malaria diagnosed by PCR during December 2007-November 2009 at a tertiary care hospital in Sabah, Malaysia. Fifty-six patients had PCR-confirmed P. knowlesi monoinfection and clinical records available for review. Twenty-two (39%) had severe malaria; of these, 6 (27%) died. Thirteen (59%) had respiratory distress; 12 (55%), acute renal failure; and 12, shock. None experienced coma. Patients with uncomplicated disease received chloroquine, quinine, or artemether-lumefantrine, and those with severe disease received intravenous quinine or artesunate. Parasite clearance times were 1-2 days shorter with either artemether-lumefantrine or artesunate treatment. P. knowlesi is a major cause of severe and fatal malaria in Sabah. Artemisinin derivatives rapidly clear parasitemia and are efficacious in treating uncomplicated and severe knowlesi malaria.

Fulltext Intravascular haemolysis in severe Plasmodium knowlesi malaria: association with endothelial activation, microvascular dysfunction, and acute kidney injury

Barber BE, Grigg MJ, Piera KA, William T, Cooper DJ, Plewes K, et al.

Emerg Microbes Infect, 2018 Jun 06;7(1):106.
PMID: 29872039 DOI: 10.1038/s41426-018-0105-2

Plasmodium knowlesi occurs throughout Southeast Asia, and is the most common cause of human malaria in Malaysia. Severe disease in humans is characterised by high parasite biomass, reduced red blood cell deformability, endothelial activation and microvascular dysfunction. However, the roles of intravascular haemolysis and nitric oxide (NO)-dependent endothelial dysfunction, important features of severe falciparum malaria, have not been evaluated, nor their role in acute kidney injury (AKI). In hospitalised Malaysian adults with severe (n = 48) and non-severe (n = 154) knowlesi malaria, and in healthy controls (n = 50), we measured cell-free haemoglobin (CFHb) and assessed associations with the endothelial Weibel-Palade body (WPB) constituents, angiopoietin-2 and osteoprotegerin, endothelial and microvascular function, and other markers of disease severity. CFHb was increased in knowlesi malaria in proportion to disease severity, and to a greater extent than previously reported in severe falciparum malaria patients from the same study cohort. In knowlesi malaria, CFHb was associated with parasitaemia, and independently associated with angiopoietin-2 and osteoprotegerin. As with angiopoietin-2, osteoprotegerin was increased in proportion to disease severity, and independently associated with severity markers including creatinine, lactate, interleukin-6, endothelial cell adhesion molecules ICAM-1 and E-selectin, and impaired microvascular reactivity. Osteoprotegerin was also independently associated with NO-dependent endothelial dysfunction. AKI was found in 88% of those with severe knowlesi malaria. Angiopoietin-2 and osteoprotegerin were both independent risk factors for acute kidney injury. Our findings suggest that haemolysis-mediated endothelial activation and release of WPB constituents is likely a key contributor to end-organ dysfunction, including AKI, in severe knowlesi malaria.

Evaluation of reported adverse drug reactions in antibiotic usage: a retrospective study from a tertiary care hospital, Malaysia

Arulappen AL, Danial M, Sulaiman SAS

Front Pharmacol, 2018;9:809.
PMID: 30177879 DOI: 10.3389/fphar.2018.00809

Adverse drug reaction (ADR) primarily caused by many drugs including antibiotics. At present, the incidence and pattern of ADR caused by antibiotics have remained as neglected area in Malaysia. This study was conducted to determine the incidence and analyze the pattern of ADR caused by antibiotics among patients in a tertiary care hospital. It is a 2-year retrospective observational study conducted at Hospital Pulau Pinang, Malaysia. All eligible patients who had antibiotic prescribed belonging to any age group either from outpatient or inpatient that had experienced ADR was included in this study. The outcomes were measured with the aid of Naranjo's and Hartwig's scales. The incidence of the ADRs among patients prescribed with antibiotics in Hospital Pulau Pinang is about 1.1%. Vancomycin and Trimethoprim/Sulfamethoxazole both are considered to be the major contributors to ADR incidences. The skin was the most affected organ by ADRs followed by gastrointestinal system. Most of the severe ADRs were caused by Penicillin. The causality relationship of all the severe reactions was mostly probable. General Medicine unit had reported the highest number of ADRs caused by antibiotics. The common manifestations of ADRs are acute kidney injury and exanthem. In addition, majority of the ADRs caused by antibiotics were reversible. A large multicenter study is suggested to confirm the present findings.

Fulltext Acute-on-chronic liver failure: consensus recommendations of the Asian Pacific association for the study of the liver (APASL): an update

Sarin SK, Choudhury A, Sharma MK, Maiwall R, Al Mahtab M, Rahman S, et al.

Hepatol Int, 2019 Jul;13(4):353-390.
PMID: 31172417 DOI: 10.1007/s12072-019-09946-3

The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. With international groups volunteering to join, the "APASL ACLF Research Consortium (AARC)" was formed in 2012, which continued to collect prospective ACLF patient data. Based on the prospective data analysis of nearly 1400 patients, the AARC consensus was published in 2014. In the past nearly four-and-a-half years, the AARC database has been enriched to about 5200 cases by major hepatology centers across Asia. The data published during the interim period were carefully analyzed and areas of contention and new developments in the field of ACLF were prioritized in a systematic manner. The AARC database was also approached for answering some of the issues where published data were limited, such as liver failure grading, its impact on the 'Golden Therapeutic Window', extrahepatic organ dysfunction and failure, development of sepsis, distinctive features of acute decompensation from ACLF and pediatric ACLF and the issues were analyzed. These initiatives concluded in a two-day meeting in October 2018 at New Delhi with finalization of the new AARC consensus. Only those statements, which were based on evidence using the Grade System and were unanimously recommended, were accepted. Finalized statements were again circulated to all the experts and subsequently presented at the AARC investigators meeting at the AASLD in November 2018. The suggestions from the experts were used to revise and finalize the consensus. After detailed deliberations and data analysis, the original definition of ACLF was found to withstand the test of time and be able to identify a homogenous group of patients presenting with liver failure. New management options including the algorithms for the management of coagulation disorders, renal replacement therapy, sepsis, variceal bleed, antivirals and criteria for liver transplantation for ACLF patients were proposed. The final consensus statements along with the relevant background information and areas requiring future studies are presented here.

Fulltext Risk of Preeclampsia and Pregnancy Complications in Women With a History of Acute Kidney Injury

Tangren JS, Wan Md Adnan WAH, Powe CE, Ecker J, Bramham K, Hladunewich MA, et al.

Hypertension, 2018 08;72(2):451-459.
PMID: 29915020 DOI: 10.1161/HYPERTENSIONAHA.118.11161

An episode of clinically recovered acute kidney injury (r-AKI) has been identified as a risk factor for future hypertension and cardiovascular disease. Our objective was to assess whether r-AKI was associated with future preeclampsia and other adverse pregnancy outcomes and to identify whether severity of AKI or time interval between AKI and pregnancy was associated with pregnancy complications. We conducted a retrospective cohort study of women who delivered infants between 1998 and 2016 at Massachusetts General Hospital. AKI was defined using the 2012 Kidney Disease Improving Global Outcomes laboratory criteria with subsequent clinical recovery (estimate glomerular filtration rate, >90 mL/min per 1.73 m2 before conception). AKI was further classified by severity (Kidney Disease Improving Global Outcomes stages 1-3) and time interval between AKI episode and the start of pregnancy. Women with r-AKI had an increased rate of preeclampsia compared with women without previous r-AKI (22% versus 9%; P<0.001). Infants of women with r-AKI were born earlier (gestational age, 38.2±3.0 versus 39.0±2.2 weeks; P<0.001) and were more likely to be small for gestational age (9% versus 5%; P=0.002). Increasing severity of r-AKI was associated with increased risk of preeclampsia for stages 2 and 3 AKI (adjusted odds ratio, 3.5; 95% confidence interval, 2.1-5.7 and adjusted odds ratio, 6.5; 95% confidence interval, 3.5-12.0, respectively), but not for stage 1 (adjusted odds ratio, 1.7; 95% confidence interval, 0.9-3.2). A history of AKI before pregnancy, despite apparent full recovery, was associated with increased risk of pregnancy complications. Severity and timing of the AKI episode modified the risk.

We present a case study of a 26-year-old morbidly obese man with a three-day history of right leg pain and swelling. The swelling was associated with low grade fever. He was alert and conscious upon presentation to the hospital. His physical examination showed gross swelling of the entire right lower limb with no systemic manifestations. There was no discharge and bullae from the swelling area of the leg. He had high blood sugar and was newly diagnosed with type 2 diabetes mellitus. He was diagnosed with necrotizing fasciitis. An intravenous imipenem-cilastatin 500 mg every 6 h together with clindamycin 900 mg every 8 h was started empirically. Extensive wound debridement was performed. The swab culture obtained intraoperatively grew Pseudomonas aeruginosa. He required an above knee amputation due to worsening infection despite wound debridement. Post-operatively, he developed acute kidney injury with severe metabolic acidosis, which required daily hemodialysis. However, the patient deteriorated due to septic shock with multi-organ failure, resulting in his death.
