Abstract Q-TMA is an acute, severe, immune-mediated, drug-induced disorder. Q-TMA is suspected when symptoms suddenly begin within hours following quinine (Q) exposure. Diagnosis of Q-TMA is established by the history of recurrent acute symptoms following recurrent Q exposures and/or by documentation of Q-dependent antibodies reactive with platelets and/or neutrophils. The Oklahoma TTP-HUS Registry enrolls all patients for whom plasma exchange (PEX) is requested for suspected TTP or HUS. Since 1995, when routine measurement of ADAMTS13 activity began, the Registry has diagnosed 78 patients with acquired TTP (ADAMTS13 <10%). During this time we have also diagnosed 17 patients with Q-TMA; 2 additional patients were diagnosed before 1995. Seventeen of these 19 patients were tested for Q-dependent antibodies; all were positive. Nine patients had a history of recurrent acute symptoms with recurrent Q exposure, including the 2 patients not tested for Q-dependent antibodies. Q exposure was a pill in 18 patients, tonic water in one. Remarkably, 18 patients were women; all 19 patients were white. Common presenting symptoms were fever, chills, nausea and vomiting. No patients had focal neurologic abnormalities. All patients had microangiopathic hemolytic anemia (MAHA), thrombocytopenia, and acute kidney injury. Eight patients had elevated serum alanine aminotransferase (231-1345 U/L). Three patients had neutropenia (absolute neutrophil counts, 184-486). Two patients had coagulation abnormalities suggesting disseminated coagulation (DIC). One patient died from complications of the central venous catheter insertion, performed for PEX and dialysis; all other patients recovered normal platelet counts. Three of the 18 surviving patients had end-stage renal disease (2 had kidney transplants). The median estimated glomerular filtration rate (GFR) for the other 15 patients, at 2.7-19.2 years (median, 10.2) after recovery, was 36 ml/min (range, 19-98). Only two patients had normal GFR (≥90 ml/min). Eleven patients had chronic kidney disease, defined by GFR <60 ml/min. Seven of 18 patients have died 4.1-12.7 years (median, 7.8) following recovery at ages 59-87 years. Conclusion. Quinine can cause severe immune-mediated toxicities involving multiple organ systems (Am J Hematol 2016; 91: 461). Q-TMA is an acute disorder causing severe kidney injury and, in some patients, also liver toxicity, neutropenia, and/or DIC. Q-TMA is not rare. During 20 years, we enrolled 17 Q-TMA patients compared to 78 patients with acquired TTP. Chronic kidney disease is a common long-term outcome. Explicit questions are required to discover the association of systemic symptoms with quinine ingestion. Table Table. Disclosures No relevant conflicts of interest to declare.

The Impact

Background: The clinical course of COVID-19 is more severe in elderly patients with cardio-metabolic co-morbidities. Chronic kidney disease is considered an independent cardiovascular risk factor. We aimed to evaluate the impact of reduced eGFR on the composite outcome of admission to ICU and death in a sample of consecutive COVID-19 hospitalized patients. Methods: We retrospectively evaluated clinical records of a consecutive sample of hospitalized COVID-19 patients. A total of 231 patients were considered for statistical analysis. The whole sample was divided in two groups on the basis of eGFR value, e.g., ≥ or < 60 mL/min/1.73 m2. Patients with low eGFR were further divided among those with a history of chronic kidney disease (CKD) and those without (AKI, acute kidney injury). The primary outcome was a composite of admission to ICU or death, whichever occurred first. The single components were secondary outcomes. Results: Seventy-nine (34.2%) patients reached the composite outcome. A total of 64 patients (27.7%) died during hospitalization, and 41 (17.7%) were admitted to the ICU. A significantly higher number of events was present among patients with low eGFR (p < 0.0001). Age (p < 0.001), SpO2 (p < 0.001), previous anti-platelet treatment (p = 0.006), Charlson’s Comorbidities Index (p < 0.001), serum creatinine (p < 0.001), eGFR (p = 0.003), low eGFR (p < 0.001), blood glucose levels (p < 0.001), and LDH (p = 0.003) were significantly associated with the main outcome in univariate analysis. Low eGFR (HR 1.64, 95%CI 1.02-2.63, p = 0.040) and age (HR per 5 years 1.22, 95%CI 1.10-1.36, p < 0.001) were significantly and independently associated with the main outcome in the multivariate model. Patients with AKI showed an increased hazard ratio to reach the combined outcome (p = 0.059), while those patients with both CKD had a significantly higher probability of developing the combined outcome (p < 0.001). Conclusions: Patients with reduced eGFR at admission should be considered at high risk for clinical deterioration and death, requiring the best supportive treatment in order to prevent the worst outcome.

Abstract Graves ophthalmopathy(GO)is the most common extra-thyroidal manifestation of Graves’ disease (GD). Most cases of GO are bilateral which may be asymmetric, whereas unilateral ophthalmopathy is less common and has been observed in 9-15% cases. Association between chronic kidney disease and unilateral Grave’s ophthalmopathy in a clinically euthyroid patient is rare. We report a case of a 24-year-old male with no previous history of any chronic medical illnesses who presented with protruded right eye for the past 6 months. He did not have any other visual symptoms or symptoms related to thyroid disease. Laboratory results revealed low TSH, normal free T3 and free T4. TSH receptor antibodies were positive. He also had elevated serum creatinine at 418 umol/L (normal levels 64 - 110 umol/L). US KUB showed bilateral small sized kidneys and increased parenchymal echogenicity suggestive of chronic kidney disease. MRI Head showed features suggestive of unilateral thyroid associated orbitopathy. Patient received 1-week course of oral prednisolone 10 mg per day after which his exophthalmos improved.Case report: A 24 year old male with no previous history of any chronic medical illnesses, presented to the clinic with protruded right eye for the past 6 months that was progressively getting worse. There was no eye pain, visual changes, ophthalmoplegia, dryness or discharge from eye. Patient did not report any other symptoms, Physical examination revealed a comfortable man with protruded right eye, lid retraction, normal eye movements and no signs of orbital cellulitis. Neck examination was significant for a mild diffuse goitre. Laboratory studies were significant for haemoglobin of 12.1 g/dl (normal 13-17 g/dl). He also had elevated serum creatinine at 418 umol/L (normal 64 - 110 umol/L). Serum electrolytes, liver function tests and lipid profile were within normal range. 24 hr urine collection showed 3.08 gm/24 hr proteinuria. Serum TSH was 0.04 mIU/L (normal 0.45 - 4.5 mIU/L), free T4 was 13.8 pmol/L (normal 9 - 20 pmol/L) and free T3 was 4.56 pmol/L (normal 2.89 - 4.88 pmol/L). Thyrotropin Receptor Ab titre was 4.69 IU/L (normal 0.00 - 1.75 IU/L). ANA, ANCA, C3, C4, Anti thyroid peroxidase and Anti GBM antibodies were negative. Screening for hepatitis B, C and HIV was negative US KUB showed bilateral small sized kidneys and increased parenchymal echogenicity suggestive of CKD. MRI Head was remarkable for proptosis of the right eye with increased retro-orbital fat, thickening and T2 hyper-intensity with sparing of the tendinous insertion involving the right inferior, medial, superior and lateral rectus muscles with crowding at the orbital apex. Features were suggestive of unilateral thyroid associated orbitopathy. Patient received 1-week course of oral prednisolone 10 mg per day after which his exophthalmos improved. An association between CKD and GO in a clinically euthyroid patient is rare.

Background: Contrast-induced acute kidney injury (CI-AKI), is an important complication of percutaneous coronary intervention (PCI). We aimed to study the role of serum midkine (MK) as an early biomarker of CI-AKI. Methods: We conducted a prospective observational cohort study. It includes 100 chronic kidney disease (CKD) patients with an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73m2. All patients were undergoing PCI for ACS. We measured serum midkine before, 2 and 24 hours after PCI.  Results: The mean age of the patients was 70.32±3.62 years, 74% males. Twenty-seven patients developed CI-AKI. The CI-AKI group has a history of diabetes mellitus (DM) and/or dyslipidemia, history of diuretics, metformin and/or angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers (ACEI/ARBs) use. The CI-AKI patients have low left ventricular ejection fraction (LVEF) (EF < 45%) and low Creatinine Clearance (CrCl) before PCI. The CI-AKI received more contrast volume, had a longer duration of PCI  and had high Mehran risk score after PCI. Comparison between the two studied groups regarding serum MK showed that there was a statistically significant difference regarding serum MK 2 hours after PCI. Receiver operating characteristic (ROC) curve analysis for serum MK showed that serum MK measured 2 hours after PCI was statistically significant to predict CI-AKI. Conclusion: An early Serum MK after PCI can be used as an early predictor of CI-AKI in ACS patients.

Abstract Background and Aims Kidney involvement, ranging from mild hematuria and proteinuria to acute kidney injury (AKI) in patients with coronavirus disease-2019 (COVID-19), is a recent finding with various incidence rates reported among hospitalized patients with COVID-19. Current evidence on AKI rate in patients hospitalized with COVID-19 and its associated risk factors is limited, especially in Iran. Method In this retrospective cohort study, we enrolled adult patients referred to the Sina hospital, Iran, from 20 February to 14 May 2020, with either a positive PCR test or a highly susceptible chest computed tomography features (CT) consistent with COVID-19 diagnosis. AKI was defined according to the kidney disease improving global outcomes (KDIGO) criteria, and patients were stratified based on their AKI staging. We evaluated the risk indicators associated with AKI during hospitalization besides in-hospital outcomes and recovery rate at the time of discharge. Results: We evaluated 516 patients with a mean age of 57.6±16.1 years and a male to female ratio of 1.69 who were admitted with the COVID-19 diagnosis. AKI development was observed among 194 (37.6%) patients, comprised of 61.9% patients in stage 1, 18.0% in stage 2, and 20.1% in stage 3. Out of all patients, AKI occurred in 58 (11.2%) patients during the hospital course, and 136 (26.3%) patients arrived with AKI upon admission. AKI development was positively associated with all of the in-hospital outcomes, including intensive care unit admissions, need for invasive ventilation, acute respiratory distress syndrome (ARDS), acute cardiac injury, acute liver injury, multi-organ damage, and mortality. Patients with stage 3 AKI showed a significantly higher mortality rate, ARDS, and need for invasive ventilation than other stages. After multivariable analysis, male sex (odds ratio (OR):11.27), chronic kidney disease (OR: 6.89), history of hypertension (OR:1.69), disease severity (OR; 2.27), and high urea levels (OR: 1.04) on admission were independent risk indicators of AKI development. Among 117 (28.1%) patients who experienced AKI and survived, only 33 (28.2%) patients made a recovery from the AKI, and 84 (71.8%) patients did not exhibit full recovery at the time of discharge. Conclusion We found that male sex, history of chronic kidney disease, hypertension, disease severity, and high serum urea were independent risk factors associated with AKI in patients with COVID-19. Also, higher stages of AKI were associated with increased risk of mortality and in-hospital complications. Our results indicate a necessity for more precise care and monitoring for AKI during hospitalization in patients with COVID-19, and lack of AKI recovery at the time of discharge is a common complication in such patients.

Difluoroethane is the active ingredient in various computer cleaners and is increasingly abused by teenagers due to its ease of access, quick onset of euphoric effects, and lack of detectability on current urine drug screens. The substance has detrimental effects on various organ systems; however, its effects on the kidneys remain largely unreported. The following case report adds new information to the developing topic of acute kidney injury in patients abusing difluoroethane inhalants. In addition, it is one of the first to show a possible relationship between prolonged difluoroethane abuse and the development of chronic kidney disease in the absence of other predisposing risk factors.

Abstract Background Novel coronavirus disease 2019 (COVID-19) emerged in Wuhan and rapidly spread, affecting &gt;10 million cases worldwide. Caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and primarily manifesting as an acute respiratory failure with interstitial and alveolar pneumonia, it can also affect multiple organs. Kidney involvement was underestimated in early reports and its role remains controversial. The aim of this study was to analyse the role of kidney damage in COVID-19 outcome. Methods This is a prospective cohort study of 1603 consecutive patients admitted in a University Reference Hospital in the heart of the European outbreak. Results Median age was 64 years, 40.4% were female, 15.2% presented diabetes mellitus, 35.7% hypertension and 20.3% obesity. On admission, the prevalence of elevated serum creatinine (sCr), proteinuria, leucocyturia and haematuria were 21.0, 37.8, 31.8 and 45.6%, respectively. In total, 43.5% of those with an elevated sCr had previous chronic kidney disease (CKD) and 11.4% of those with normal sCr developed an in-hospital acute kidney injury (AKI); 17 patients needed acute haemodialysis; and 197 patients died during hospitalization. Cox proportional hazard regression confirmed that elevated baseline sCr [hazard ratio (95% confidence interval) 2.40 (1.79–3.22)], previous CKD [1.59 (1.06-2.37)], haematuria [1 + 1.68 (0.92–3.06), 2–3 + 2.69 (1.49–4.87)] and in-hospital AKI [1.50 (0.92–2.44)] were independent risk factors for in-hospital death after adjusting for age, sex and comorbidity. Conclusion The prevalence of acute and chronic kidney disease on admission and in-hospital AKI is higher than previously reported in Wuhan, and is associated with high in-hospital mortality. We should increase our awareness towards kidney involvement and design specific strategies for management of COVID-19 in these patients.
