RESUMO
Heart failure, in its diverse forms based on the value of the ejection fraction, is associated to high mortality and the frequent need for hospitalization, with a consequent heavy burden on healthcare resources. For an appropriate treatment of heart failure with preserved ejection fraction (HFpEF), there are no specific drugs effective for this condition. Those indicated in HF with reduced EF (HFrEF) are of more benefit in that form of HF, according to the guidelines of the European Society of Cardiology of 2016: ACE-inhibitors, beta-blockers, anti-aldosterones are all indicated with a class of recommendation/level of evidence IA; therapy with loop diuretics is indicated in the case of clinical congestion (IB). Studies carried out with ACE-inhibitor (or angiotensin-receptor antagonist) or beta-blocker or anti-aldosterone to evaluate their efficacy also in HFpEF have substantially shown a benefit only on a reduction in the hospitalization rate. The same guidelines identify regular aerobic activity (IA) as more effective in the condition of HFpEF and indicate, appropriately, the need to treat comorbidities (IC) in the elderly (where they are more present and more numerous). They also recommend to avoid certain associations of drugs and, obviously, harmful (and contraindicated) medications that could worsen the clinical picture or might be potentially lethal.
RESUMO
INTRODUCTION: Eosinophilic granulomatosis with polyangiitis is a rare and potentially fatal disease if not readily diagnosed. Cerebral involvement is extremely rare and clinical presentation as hemorrhagic stroke is even rarer. CASE PRESENTATION: A 58-year-old Caucasian man was admitted to our medical unit because of a computed tomography-diagnosed hemorrhagic stroke with right-sided hemiparesis and fever. A chest computed tomography scan also revealed multiple bilateral pulmonary infiltrates; coronary artery, and carotid and left vertebral artery calcifications were also observed. Empiric antimicrobial therapy with cephalosporins was promptly undertaken; low-molecular-weight heparin was introduced as prophylaxis for venous thromboembolism. Over the following days, magnetic resonance imaging scans showed a regression of the hemorrhagic framework, also revealing hypoxic areas consistent with acute ischemic lesions. With a computed tomography scan showing a worsening of his pulmonary framework, antimicrobial therapy was modified and corticosteroids were introduced. A new blood cell count revealed further increased leukocytosis (17.49 × 10(3) µL), characterized by a surprising rise of eosinophilic cells (32.8%). Angiography of the coronary arteries found diffuse dilatations with severe signs of endothelial damage. Such an unexpected framework induced a strong suspicion that the stroke was the expression of a systemic vasculitis, which had triggered his cerebral, coronary, and pulmonary frameworks. The search for antineutrophil cytoplasmic antibody was positive for perinuclear antineutrophil cytoplasmic antibody, and eosinophilic granulomatosis with polyangiitis was diagnosed. Explaining to the patient the rarity of his disease, and what the most typical presentations of eosinophilic granulomatosis with polyangiitis were, he revealed that before admission he had had scalp injuries, in the nuchal region, and had taken corticosteroids as self-medication, with subsequent disappearance of the lesions. Therefore, high-dose corticosteroid treatment was started, and at discharge he was in good clinical condition with a slight right-sided hyposthenia. CONCLUSIONS: A diagnosis of eosinophilic granulomatosis with polyangiitis is often difficult, but we are convinced that intake of corticosteroids on a self-prescribed basis may have obscured the clinical presentation. Therefore, this case also suggests how the growing phenomenon of self-medication can be harmful, and that a careful investigation of clinical history is still an act of paramount importance.
