Outcomes of reperfusion therapy for acute ischaemic stroke in patients aged 90 years or older: a retrospective study.

The benefits and risks of acute reperfusion therapy (RT) in acute ischaemic stroke (AIS) remain uncertain in older patients, especially in nonagenarians. We aimed to assess the impact of RT in this population. Single-center retrospective cohort study comparing patients ≥ 90 years old admitted to a Stroke Unit (2008-2018) with AIS, submitted or not to RT [intravenous thrombolysis(IVT), mechanical thrombectomy(MT) or both]. Baseline characteristics, in-hospital complications and 3-month outcomes were compared. The primary outcome was 3-month "favorable outcome", defined as modified Rankin Scale score 0-2 or equal to pre-stroke. Secondary outcomes were haemorrhagic transformation (HT) and 3 months mortality. We included 167 patients (median age 92 years, 66.5% females); 46.1% underwent RT (59 IVT, 11 MT, 7 both). RT group had higher admission National Institutes of Health Stroke Scale (NIHSS) (16 versus 9.5, p < 0.001). Favorable outcome occurred in only 22% of patients, with no differences between groups; its odds decreased with higher NIHSS scores (OR 0.80, 95%CI 0.73-0.87, p < 0.001) and with the development of in-hospital respiratory infection (OR 0.22, 95%CI 0.07-0.67, p = 0.007). HT occurred in 16.2% of patients, being more prevalent (26.0% versus 7.8%, p = 0.001), symptomatic (14.3% versus 3.3%, p = 0.011) and severe (PH1/2 15.6% versus 2.2%, p = 0.012) in the RT group, although it did not influence the primary outcome. Mortality was 32% at 3 months, with no difference between groups. Although patients submitted to RT had worse admission NIHSS and increased HT, they had similar functional outcome at 3 months. Stroke severity and in-hospital respiratory infections were the most important predictors of 3 months' functional outcome.

Systolic function recovery in Heart Failure: Frequency, prognostic impact and predictors.

BACKGROUND: Systolic function recovery in patients with Heart failure (HF) with reduced ejection fraction (EF) is well recognized but not completely understood. We aimed to characterize HF patients with systolic function recovery, its prognostic impact and predictors. METHODS: We analysed patients followed in a HF clinic (2006-2015) with 2 echocardiograms performed. Partial recovery: EF recovery without attaining EF ≥ 50%; total recovery: patients reached EF ≥ 50%. Median follow-up from first echocardiogram: 69 months. Multivariate logistic regression models to determine recovery predictors. RESULTS: We analysed 304 patients with at least mild left ventricular dysfunction. During a median 34 months between echocardiogram re-evaluation 150 (49.3%) patients showed no EF recovery; 55 (18.1%) had partial recovery and 99 (32.6%) totally recovered. Mean patients age: 66; 71.1% men, high comorbidity burden; ischemic HF: 35.5%. Non-recovered patients were mostly men (80.7% vs 61.8% in partially; 61.6% in fully-recovered) with ischemic HF (46.0% vs 32.5% in partially; 21.2% in fully-recovered). Comorbidity burden, NYHA class and therapy were similar. During follow-up, 156 patients (46.7%) died. Patients with total recovery had a multivariate-adjusted 54% lower risk of dying when compared to non-recovered. Partially-recovered patients showed a non-significant adjusted 8% mortality reduction. Independent predictors of systolic function recovery were female gender(OR: 2.17, 95% CI 1.11-4.35), non-ischemic aetiology (OR: 2.78, 95% CI 1.35-5.56), and end diastolic left ventricular diameter < 60 mm (OR: 3.12, 95% CI 1.56-6.25). CONCLUSIONS: HF-recovered patients were mainly women with non-ischemic HF and smaller left ventricles. These patients had significantly better prognosis than those with persistently reduced EF.

Non-occlusive Mesenteric Ischaemia and Acute Kidney Injury: A Case Report of Severe Idiopathic Systemic Capillary Leak Syndrome.

Systemic capillary leak syndrome is a rare, underdiagnosed and life-threatening disease characterized by periodic episodes of hypovolaemic shock due to leakage of plasma from the intravascular to the extravascular space. It is associated with haemoconcentration, hypoalbuminaemia and generalized oedema. We report the case of a patient with a history of emergent extensive small and large bowel resection and several episodes of hypovolaemic shock with acute renal injury, who presented with abdominal pain, headache and generalized oedema. Severe systemic capillary leak syndrome was diagnosed after a complex diagnostic approach. This case report describes the acute and prophylactic treatment administered to the patient and the 4-year follow-up. We highlight the importance of timely recognition and prompt treatment, as well as the need for new investigations to prevent the serious and unusual complications seen in this case. LEARNING POINTS: Idiopathic systemic capillary leak syndrome (ISCLS) should be suspected in the presence of the triad of hypotension, haemoconcentration and hypoalbuminaemia; the diagnostic work-up is challenging and requires exclusion of several causes of hypotension and shock of uncertain aetiology.Acute mesenteric ischaemia leading to extensive and emergent bowel resection is an irreversible but atypical complication of ISCLS; other complications include myocardial oedema and deep vein thrombosis.ISCLS is characterized by three phases; supportive as well as prophylactic treatment adapted to each phase is crucial for prognosis and to avoid end-organ damage.

Efficacy of Rituximab in Refractory Inflammatory Myopathy Associated With Coexistence of Behçet's Disease and Antiphospholipid Syndrome.

A 43-year-old Caucasian male initiated myalgias and loss of muscle strength in the upper and lower limbs, but especially at the shoulder and pelvic girdle. Creatinine phosphokinase was elevated seven-fold above the normal reference value and aldolase was slightly elevated. He had a previous diagnosis of Behçet's disease, antiphospholipid syndrome and hypertriglyceridaemia. At this time, he was on azathioprine 150 mg daily, colchicine 1 mg daily, warfarin and fenofibrate 200 mg daily. Fenofibrate was stopped and creatinine phosphokinase re-evaluated 2 months later, but it was higher, with persistent myalgias. By this time, prednisolone was restarted and the azathioprine dose reduced until it was discontinued. Nevertheless, 2 months after stopping azathioprine, the patient remained symptomatic and creatinine phosphokinase was persistently elevated. At this point, the authors requested myositis antibody testing to exclude overlap with a third autoimmune disorder, and Ro52 antibody was positive. Electromyography was normal. Magnetic resonance imaging of lower limb muscles was compatible with polymyositis. Muscular biopsy of the medial gastrocnemius revealed inflammatory myopathy. The authors proposed treatment with rituximab and after 3 months, the patient had clinically and analytically improved, with reduction of creatinine phosphokinase, without adverse reactions. As we can see in this case, rituximab could be a secure treatment for patients with idiopathic inflammatory myopathy without improvement on glucocorticoids plus another immunosuppressive agent. This patient has a rare overlap syndrome, since this is the first case of an association between inflammatory myopathy, Behçet's disease and antiphospholipid syndrome described in the literature. LEARNING POINTS: This is the first case report in the literature of an association between inflammatory myopathy, Behçet's disease and antiphospholipid syndrome.Rituximab could be a secure treatment for refractory idiopathic inflammatory myopathy.This case report highlights the importance of a methodical diagnostic work-up for an accurate diagnosis.

Whipple's Disease as the First Manifestation of Chronic Lymphocytic Leukaemia.

Whipple's disease is a rare multisystemic infectious disease that can mimic lymphoproliferative disorders and must be considered in the differential diagnosis of febrile syndromes. The authors describe the case of a 55-year-old man who presented to the Emergency Department with dyspnoea and abdominal pain. He had a 2-month history of fever, night sweats, asthenia and unintentional weight loss. Upon clinical examination he had bilateral inguinal lymphadenopathy. Blood tests showed iron-deficit anaemia and high C-reactive protein. Abdominal ultrasound showed mesenteric and iliac adenopathies and hepatosplenomegaly. The patient was admitted to the Internal Medicine department for additional testing. Flow cytometry analysis of peripheral blood showed CD5-positive monoclonal B-cell expansion. Excisional biopsy of a retroperitoneal adenopathy guided by computed tomography showed periodic acid-Schiff-positive bacilli inside the macrophages, further identified as Tropheryma whipplei through polymerase chain reaction. Bone marrow biopsy showed a scarce positive CD5 lymphoid population and haematopoietic alterations related to infection. The patient started treatment for T. whipplei with complete symptom resolution. This is the first case describing the simultaneous diagnosis of Whipple's disease and chronic lymphocytic leukaemia in a patient with constitutional symptoms, fever and lymphadenopathies. LEARNING POINTS: Whipple's disease can mimic lymphoproliferative disorders and should be considered in the differential diagnosis of lymphadenopathy and fever, even in the absence of gastrointestinal symptoms.Most patients with chronic lymphocytic leukaemia are asymptomatic, but a minority have B symptoms and increased risk of infections.An accurate clinical history and differential diagnosis are fundamental; if the authors had not had a high level of suspicion, this patient could have been diagnosed with just chronic lymphocytic leukaemia and may have died if Whipple's disease had been left untreated.
