Aims: Endovascular therapy (EVT) is a highly effective stroke treatment, but it requires the administration of contrast media which puts patients at risk of acute kidney injury (AKI). AKI is associated with increased morbidity and mortality in cardiovascular patients.Methods: PubMed, Scopus, ISI and the Cochrane Library were systematically searched for observational and experimental studies assessing the occurrence of AKI in adult acute stroke patients submitted to EVT. Two independent reviewers collected study data regarding study setting, period, source of data, and AKI definition and predictors, the outcomes of interest being AKI incidence and 90-day death or dependency (modified Rankin Scale score ≥3). These outcomes were pooled using random effect models, and heterogeneity was measured using the I2statistic.Results: 22 studies were identified and included in the analysis, involving 32 034 patients. Pooled incidence of AKI was 7% (95% CI 5% to 10%), but heterogeneity was high across studies (I2=98%), and not accounted for by the definition of AKI used. The most frequently reported AKI predictors were impaired baseline renal function (5 studies) and diabetes (3 studies); 3 studies (2103 patients) reported data on death and 4 studies (2424 patients) reported data on dependency. Overall, AKI was associated with both outcomes, with ORs of 6.21 (95% CI 3.52 to 10.96) and 2.86 (95% CI 1.88 to 4.37), respectively. Heterogeneity was low for both analyses (I2=0%).Conclusions: AKI affects 7% of acute stroke patients submitted to EVT and identifies a subgroup of patients for which treatment outcomes are suboptimal, with an increased risk of death and dependency.

Eosinophilic fasciitis is a systemic inflammatory disease characterized by symmetrical swelling and skin induration of the distal portions of the arms and/or legs, evolving into a scleroderma-like appearance, accompanied by peripheral blood eosinophilia. It is a rare disease with a poorly understood etiology. Corticosteroid treatment remains the standard therapy, either taken alone or in association with an immunosuppressive drug. This paper presents a case of a male patient with palpebral edema and marked eosinophilia, diagnosed with intestinal parasitic infection in October 2006. He was treated with an antiparasitic drug, but both the swelling and the analytical changes remained. This was followed by a skin and muscle biopsy, which turned out to be compatible with eosinophilic fasciitis. There was progressive worsening of the clinical state, with stiffness of the abdominal wall and elevated inflammatory parameters, and the patient was referred to the Immunology Department, medicated with corticosteroids and methotrexate. Over the years there were therapeutic adjustments and other causes were excluded. Currently the patient continues to be monitored, and there is no evidence of active disease. The case described in this article is interesting because of the diagnosis of eosinophilic fasciitis probably associated/coexisting with a parasite infection. This case report differs from others in that there is an uncommon cause associated with the onset of the disease, instead of the common causes such as trauma, medication, non-parasitic infections or cancer.

Background/Objectives: Acute kidney injury (AKI) is a potential complication of cardiovascular disorders and is associated with worse outcome. The aim of this study was to assess the incidence of early AKI after endovascular therapy for acute ischemic stroke, identify predictors for this complication, and test the association between AKI and mortality or death or dependency. Methods: This was a single-center cohort study involving consecutive patients with acute ischemic stroke submitted to endovascular therapy between 2015 and 2022. AKI was defined according to the KDIGO criteria and evaluated at 48 h. Other outcomes of interest were vital status and functional dependency at 3 months using the modified Rankin Scale, with death or dependency being defined as a score > 2. An adjustment for potential confounders was performed using logistic regression. Results: Overall, 1150 patients were included in the analysis, with a mean age of 74 years and a slight female preponderance (56%). The median NIHSS was 15, the mean onset-to-groin time was 392 min, and 92% of patients were successfully recanalized. The overall incidence rate of AKI was 6%. On univariate analysis, patients with AKI were older (p = 0.002), had a longer time to EVT (p = 0.042), higher NIHSS (p = 0.006), higher blood glucose (p = 0.033), and lower baseline glomerular filtration rate (GFR) (p < 0.001). After adjustment for confounders, AKI was independently associated with NIHSS (p = 0.012), time to treatment (p = 0.004), and lower baseline GFR (p < 0.001). AKI was also independently associated with higher mortality (OR = 2.302, p = 0.003). Conclusions: Patients with impaired baseline renal function and more severe stroke are at higher risk of AKI, and AKI begets worse stroke outcome. Better strategies are required to optimize treatment outcome in these patients and avert this vicious cycle.
