Attenuation of COVID-19-induced cytokine storm in a young male patient with severe respiratory and neurological symptoms.

Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), the etiological agent of coronavirus disease 2019 (COVID-19), produces protean manifestations and causes indiscriminate havoc in multiple organ systems. This rapid and vast production of proinflammatory cytokines contributes to a condition termed cytokine storm. A 35-year-old, otherwise healthy, employed, male patient was tested positive for COVID-19. He was admitted to the hospital on disease day 10 due to retarded verbal reactions and progressive delirium. On account of these conditions and the need for noninvasive/invasive ventilation, a combination treatment with baricitinib and remdesivir in conjunction with standard of care was initiated. The cytokine storm was rapidly blocked, leading to a vast pulmonary recovery with retarded recovery of the central nervous system. We conclude that the rapid blockade of the COVID-19-induced cytokine storm should be considered of avail as a principle of careful decision-making for effective recovery.

Recommendations for driving after implantable cardioverter defibrillator implantation and the use of a wearable cardioverter defibrillator : Different viewpoints around the world.

The use of implantable cardioverter defibrillators (ICD) has been shown to improve survival in patients at risk of sudden cardiac death; however, due to the continuous risk of sudden loss of consciousness during arrhythmia or ICD intervention, they pose a potential risk to other road users while driving. A large number of opinions and recommendations from authorities and medical societies all over the world exist regarding driving restrictions after ICD implantation. This analysis provides an overview of the recommendations on driving restrictions from several countries. Furthermore, the use of the wearable and the subcutaneous ICD are taken into account.

Lipoprotein apheresis - Shortening of treatment intervals reduces cardiovascular events: Case reports.

BACKGROUND: Lipoprotein (Lp-) apheresis is a life-long therapy, usually performed in weekly intervals. In some cases, however, atherosclerotic disease progresses despite adequate therapy with weekly Lp-apheresis and maximal lipid lowering medication. In an attempt to improve the effectiveness of therapy, we temporarily shortened treatment intervals of Lp-apheresis in patients with elevated lipoprotein(a) (Lp(a)) and further progression of coronary atherosclerosis despite weekly Lp-apheresis and maximal lipid lowering medication. METHODS: We illustrate three case reports of patients with elevated Lp(a), who underwent regular weekly Lp-apheresis treatment for secondary prevention. The intensified treatment protocol contained three therapies in two weeks (alternating 2 per week and 1 per week). RESULTS: The shortening of treatment intervals achieved a stabilization of atherosclerotic disease in case 1. After a total of 68 therapies in 52 weeks (1.31 sessions/week) the elective coronary angiography revealed excellent long-term results. In case 2, the intensified treatment protocol is still ongoing. The patient reported a decrease in angina pectoris and an increase in exercise capacity since the beginning of more frequent therapy sessions. In some cases, as it is shown in case 3, a fast decision for shortening the treatment intervals is necessary. CONCLUSIONS: The intensified treatment regimen resulted in an improvement in clinical symptoms and no further progression of atherosclerosis. In conclusion, shorter therapeutic Lp-apheresis intervals, at least temporarily, should be considered in patients who suffer from clinical and/or angiographic progression of atherosclerosis, despite maximal lipid lowering medication and weekly Lp-apheresis.

Lipoprotein apheresis in Austria - Reduction of cardiovascular events by regular lipoprotein apheresis treatment.

BACKGROUND: In Austria, about 12 patients per 1 million inhabitants are treated currently with lipoprotein (LP-) apheresis. In 2016 it has been suggested, that about 5000 patients were treated worldwide with LP-apheresis, more than half of them in Germany. Regular LP-apheresis aims to decrease apolipoprotein B-rich lipoproteins and to reduce cardiovascular events. In this analysis we present the current situation of LP-apheresis in Austria and we evaluated the cardiovascular event rate 2 years before versus 2 years after starting LP-apheresis. METHODS: A retrospective analysis of 30 patients (19 men and 11 women) was performed at Athos Institute, Vienna, Austria. The study period included two years prior versus two years after the beginning of LP-apheresis. Cardiovascular events and interventions were defined as regarding the coronary (MACE) or the non-coronary (peripheral, cerebral or renal) vascular system. RESULTS: The first cardiovascular event before treatment initiation occurred at a mean age of 48.4 years (range 34-73), treatment was started at a mean age of 55.6 years (range 34-73). The mean rate of incidence of cardiovascular events per patient per 2 years before beginning of LP-apheresis (y-2 and y-1) versus 2 years during treatment (y+1 and y+2) was reduced by 77.78% (1.50 versus 0.33 events/patient/2 years, p = 0.003). CONCLUSIONS: The significant reduction in MACE and vascular disease during regular LP-apheresis at weekly intervals is consistent with data from the literature. Difficulties arise in comparing such studies due to different definition of events or interventions and different study durations. However, LP-apheresis is an efficient treatment option and causes significantly prolonged event-free survival for patients at risk.

Statin-induced muscular side effects at rest and exercise - An anatomical mapping.

BACKGROUND AND AIMS: Muscle-related symptoms with or without creatine kinase (CK) elevation are common adverse effects associated with statin use. Symptoms are ranging from benign myalgia to myositis and in rare cases to rhabdomyolysis. The aim was to characterize and describe muscular side effects and create an anatomical frequency mapping. METHODS: The prospective observational study was performed at a large lipidology outpatient unit in Vienna. 1111 consecutively admitted patients with muscular side effects on statin monotherapy were included during a 4-year period. Anatomical mapping of the affected muscles, signs and symptoms, the onset of symptoms after starting statin therapy and disappearance after cessation of treatment was assessed. RESULTS: In 96.5% of the patients with muscle symptoms, there was no elevation of CK. The anatomical mapping revealed exercised muscles as being mainly affected in 84%. In the upper extremity, symptoms were mainly described at the dominating side. Mostly affected muscles were the pectoral (61.4%), followed by the quadriceps femoris (59.8%), the biceps brachii (54.3%) and the deltoid (22.5%) muscles. The majority of symptoms (76.9%, n = 854) appeared within 29 days. Symptoms disappeared after discontinuation of statin therapy at a mean of 5.4 days. CONCLUSIONS: Physical activity seems to be a key trigger for onset of statin-induced muscular side effects. The appearance of symptoms can be symmetrical, asymmetrical, generalized or in isolated muscle groups only. Different statins usually produce similar symptoms, but often some patients tolerate one statin better than another.

[Therapeutic options in hyperlipidemia]. / Therapieoptionen von Fettstoffwechselstörungen.

Treatment of lipid disorders (dyslipidemia) is the cornerstone of atherosclerosis prevention and reduction of progression. Lifestyle modification is the first step to improve the plasma lipid profile. Statins play a central role in the reduction of LDL cholesterol. Whether and to what extent other lipids such as triglycerides or lipoprotein(a) should also be treated depends on the extent of atherosclerotic disease and its progression over time. Especially in residential cardiac rehabilitation we have the opportunity to encourage adherence and adapt medication as necessary due to a face to face contact over 4 weeks. Moreover, the prescription for a PCSK9-inhibitor could be resolved or the indication for a lipoprotein apheresis could be considered.

Scintigraphic perfusion defects due to right ventricular apical pacing: a pitfall in clinical cardiology.

Right ventricular apical pacing (RVAP) with a left bundle branch block on the electrocardiogram may result in regional wall motion abnormalities and decreased left ventricular function (LVF). Furthermore, perfusion defects in dipyridamole technetium-99m-methoxisobutylisonitrile ((99m)Tc-MIBI) myocardial perfusion imaging may occur despite a normal coronary angiogram. In a 68 years old patient, RVAP resulted in regional wall motion abnormalities, markedly decreased LVF and perfusion defects in dipyridamole (99m)Tc-MIBI myocardial perfusion imaging by single photon emission tomography (SPET). Coronary angiography excluded coronary heart disease. Reprogramming of the pacemaker resulted in physiologic activation of the ventricles. Echocardiography showed a normal LV systolic function. Repeated myocardial perfusion imaging was unremarkable. In conclusion, our case confirms thatRVAP may lead to scintigraphic perfusion defects and wall motion abnormalities despite a normal coronary angiogram and this differentiate between ischemia-induced perfusion defects.
