Background: Lowering blood pressure intensively in acute intracerebral hemorrhage (ICH) is associated with acute kidney injury (AKI). Blacks have a higher incidence of ICH as well as kidney disease. In addition, CT angiography (CTA), which may also be associated with AKI, is often done in acute ICH. Our objective was to investigate the relationship between aggressive BP management, CTA, race ethnicity and the risk of developing AKI in patients presenting with ICH. Methods: Patients with spontaneous ICH hospitalized in 2017 and 2018 were included. Patients with underlying arteriovenous malformations, brain metastases, and aneurysms, were excluded. We calculated the difference between the highest and lowest systolic blood pressure (SBP) during the first 24 hours of admission. Creatinine levels at admission were compared to the highest creatinine during the first 7 days after admission. AKI was defined as absolute increase in creatinine of >0.3 or 50% increase from baseline creatinine. Linear regression models were used to assess the association between SBP difference, history of CTA and AKI. Results: A total of 289 patients were included (mean±SD age 63±13), 40% were women, 41% Hispanics and 47% blacks. The majority of the patients underwent CTA (71%). The prevalence of AKI was high (30%). Blacks showed a significantly higher SBP compared to whites and Hispanics (p=.02), but no difference was found in AKI incidence (33% in Blacks vs. 27% in Caucasians and Hispanics (p=0.7). Higher BUN, creatinine and SBP on admission were associated with AKI (p=.001, p<.0001, and p=.0001, respectively). Those who developed AKI had a greater mean drop of SBP in 24 hours compared to those who did not (103mmHg vs. 84mmHg, p=.0007) and a higher prevalence of diabetes (p=.0013). In fully adjusted models, AKI was associated with SBP drop (p=.0003), but not with race/ethnicity (p=.6) or CTA (p=.06). Conclusion: We confirm, in a real-life ICH population, the association between intense blood pressure lowering and development of AKI. Race/ ethnicity and CTA were not independently associated with AKI. Our findings do not suggest that obtaining a CTA in acute ICH poses significant additional risks on developing AKI.

Background: Elevated blood pressure (BP) in the first 24 hours of admission of acute intracerebral hemorrhage (ICH) has been the focus of intensive therapeutic investigation, although early intensive BP lowering addresses a concern about development of acute kidney injury (AKI). However, it is unclear as to the effect of BP measure including the absolute BP reduction and increased BP variability on AKI in patients with acute ICH. Methods: We retrieved data of consecutive patients with acute ICH from our prospective stroke registry between July 2015 and August 2017. We excluded patients with preexisting end-stage renal disease or in-hospital death within 24 hours. The primary outcome was AKI within 7days after admission defined using the AKI Network criteria. We recorded BP on emergency department arrival and for every 1 hour from 1 to 24 hours after admission (25 measurements). We measured mean systolic BP (SBP) and maximum minus minimum SBP within both 12 hours and 24 hours, and also quantified SBP variabilities (SBPV) including standard deviation, coefficient of variation, successive variation, and average real variability. Results: Among 361 patients with ICH (age 72.7±12.8, male 55%, non-lobar 76%), 31 (9%) developed AKI. For all SBP measure, the 12-hour SBP reduction was associated with the increased risk of AKI in multivariable analysis (odds ratio [per10 mmHg increase] 1.30; 95% CI 1.10-1.35). There was no significant association between the SBP variability and risk of AKI. The area under the receiver operating characteristic curve of the 12-hour SBP reduction for predicting AKI was 0.75. The association between the 12-hour SBP reduction and AKI was not modified by preexisting chronic kidney disease (interaction P=0.40). Conclusion: Early BP reduction in the first 12 hours of admission contributed to the risk of AKI in acute ICH. This may have clinical implication to avoid excess absolute BP reduction in patients with acute ICH.

Background and Purpose: We determined the rates and predictors of acute kidney injury (AKI) and renal adverse events (AEs), and effects of AKI and renal AEs on death or disability in patients with intracerebral hemorrhage. Methods: We analyzed data from a multicenter trial which randomized 1000 intracerebral hemorrhage patients with initial systolic blood pressure ≥180 mm Hg to intensive (goal 110–139 mm Hg) over standard (goal 140–179 mm Hg) systolic blood pressure reduction within 4.5 hours of symptom onset. AKI was identified by serial assessment of daily serum creatinine for 3 days post randomization. Results: AKI and renal AEs were observed in 149 patients (14.9%) and 65 patients (6.5%) among 1000 patients, respectively. In multivariate analysis, the higher baseline serum creatinine (≥110 μmol/L) was associated with AKI (odds ratio 2.4 [95% CI, 1.2–4.5]) and renal AEs (odds ratio 3.1 [95% CI, 1.2–8.1]). Higher area under the curve for intravenous nicardipine dose was associated with AKI (odds ratio 1.003 [95% CI, 1.001–1.005]) and renal AEs (odds ratio 1.003 [95% CI, 1.001–1.006]). There was a higher risk to death (relative risk 2.6 [95% CI, 1.6–4.2]) and death or disability (relative risk 1.5 [95% CI, 1.3–1.8]) at 90 days in patients with AKI but not in those with renal AEs. Conclusions: Intracerebral hemorrhage patients with higher baseline serum creatinine and those receiving higher doses of nicardipine were at higher risk for AKI and renal AEs. Occurrence of AKI was associated higher rates of death or disability at 3 months. Registration: URL: https://clinicaltrials.gov . Unique identifier: NCT01176565.

Background: Aggressive systolic blood pressure (SBP) reduction may precipitate acute kidney injury (AKI) because of underlying hypertensive nephropathy, in subjects with intracerebral hemorrhage (ICH). Rate and determinants of AKI during acute hospitalization among ICH subjects were analyzed using a post hoc analysis of randomized, multicenter, two-groups, open-label clinical trial. Methods: Antihypertensive Treatment of Acute Cerebral Hemorrhage (ATACH) 2 trial data was analyzed. Subjects with ICH (volume <60 cm 3 ) and a Glasgow Coma Scale (GCS) score of 5 or more were randomized to a SBP target of 110 to 139 mm Hg (intensive treatment) or a target of 140 to 179 mm Hg (standard treatment). IV nicardipine was given within 4.5 hours of symptom onset to lower SBP. Serum creatinine was ascertained at baseline, 24, 48 and 72 hours after randomization. AKI was classified based on increase in serum creatinine levels from baseline, stage 1 ≥ 0.3 mg/dl (≥ 26.4umol/L) or (>1.5 to 2-fold), stage 2 (>2 to 3-fold) and stage 3 (>3-fold) were identified. Results: Of 1000 randomized subjects, 158 developed AKI (65% were men; mean age of 61.5±13.2 years). Severity of AKI was grade I, II, III in 15.3%, 0.1%, and 0.4% patients, respectively. The rate of AKI was similar in intensive and standard treatment group (16.4% versus 15.2%, P=N.S). AKI incidence was significantly higher in subjects with baseline creatinine greater than 1.2 mg/dl (36% compared to 14%, OR 3.4, 95% CI 2.3-4.9, P= <0.0001). There was no significant association between subjects with AKI and hypertension (RR 1.1, 95% CI 1-1.2, P=0.15) or diabetes mellitus type 2 (RR 0.72, 95% CI 1.5-1.1, P=0.12). Patients with GCS ≤ 12 had significantly lower chances of developing AKI (RR 0.5, 95% CI 0.4-0.9, P=0.01). The incidence of hematoma expansion (OR 2.5, 95% CI 0.6-11, P=0.2) was not significantly higher in the subjects with AKI. No significant association was observed between occurrence of AKI and death or disability (modified Rankin score 4-6) at 3 months post randomization (RR 1.1, 95% CI 0.9-1.3, P=0.44). Conclusions: Mild AKI is frequent among intracerebral hemorrhage subjects undergoing SBP reduction. However, the rate of AKI was not different between subjects who were randomized to intensive or standard treatments.

Abstract Background Leptospirosis is a zoonotic spirochetal disease caused by Leptospira interrogans. The clinical presentation ranges from an asymptomatic state to a fatal multiorgan dysfunction. Neurological manifestations including aseptic meningitis, spinal cord and peripheral nerve involvement, cranial neuropathies and cerebellar syndrome are well recognized with varying frequencies among patients with this disease. Posterior reversible encephalopathy syndrome is a very rare occurrence in leptospirosis and only two cases are reported in the medical literature up to now. We report a case of posterior reversible encephalopathy syndrome in a patient with leptospirosis with rhabdomyolysis and acute kidney injury. Case presentation A 21 year-old male presented with fever and oliguric acute kidney injury with rhabdomyolysis. A diagnosis of leptospirosis was made and he was being managed according to the standard practice together with regular hemodialysis. The clinical condition was improving gradually. On day 8 of the illness, he developed headache and sudden painless complete bilateral vision loss followed by several brief generalized tonic clonic seizure attacks. Examination was significant for a Glasgow Coma Scale of 14/15, blood pressure of 150/90 mmHg and complete bilateral blindness. The findings of magnetic resonance imaging of the brain were compatible with posterior reversible encephalopathy syndrome. He was managed with blood pressure control and antiepileptics with supportive measures and standard treatment for leptospirosis and made a complete recovery. Conclusion Posterior reversible encephalopathy syndrome, though very rare with leptospirosis, should be considered as a differential diagnosis in a patient with new onset visual symptoms and seizures, especially during the immune phase. Optimal supportive care together with careful blood pressure control and seizure management would yield a favourable outcome in this reversible entity.

Abstract Background Pregnancy-related acute kidney injury (Pr-AKI) is associated with maternal and fetal morbidity and mortality. There are few studies focusing on Pr-AKI at high altitude in the literature. Objectives to investigate the incidence, etiology, clinical features and maternal-fetal outcomes of Pr-AKI in women living at high altitude. Methods 6,512 pregnant women attending the Department of Obstetrics & Gynecology at local hospital from January 2015 to December 2018 were screened for Pr-AKI. Patients with serum creatinine above normal range(> 70umol/L) then underwent assessment to confirm the diagnosis of Pr-AKI. AKI was diagnosed and staged based on Kidney Disease Improving Global Outcomes(KDIGO) guideline. Individuals meeting the Pr-AKI criteria were recruited. Their clinical data were recorded and retrospectively analyzed. Results Pr-AKI was identified in 136/6512(2.09 %) patients. Hypertensive disorders of pregnancy(HDP) was the leading cause of Pr-AKI(35.3 %). 4(2.9 %) women died and the majority(86.1 %) had recovered renal function before discharge. Fetal outcomes were confirmed in 109 deliveries with gestational age ≥ 20 weeks. Pre-term delivery occurred in 30(27.3 %) cases and perinatal deaths in 17(15.5 %). The rate of low birth weight infant(LBWI) and intrauterine growth restriction(IUGR) was 22.0 and 10.9 % respectively. 16(14.5 %) infants were admitted to NICU after birth. Patients with HDP had a higher cesarean rate(56.3 %). More IUGR(25.0 %) and LBWI(37.8 %) were observed in their infants with a higher risk of admission to NICU(22.0 %). High altitude might have an adverse impact on HDP-related Pr-AKI patients with earlier terminated pregnancy and more stillbirth/neonatal death. Logistic regression models indicated that uncontrolled blood pressure, high altitude and advanced AKI were associated with adverse fetal outcomes in HDP-related Pr-AKI patients. Conclusions Pr-AKI was not rare in high-altitude regions and caused severe fetal morbidities and mortalities. Uncontrolled blood pressure, high altitude and advanced AKI were all risk factors for adverse fetal outcomes in Pr-AKI patients, especially for those with hypertensive disorders of pregnancy.
