[NONINVASIVE MECHANICAL VENTILATION IN CHRONIC OBSTRUCTIVE LUNG DISEASES WITH ACUTE OR CHRONIC RESPIRATORY FAILURE]

BALIKÓ Zoltán

[Over the past decade, the use of noninvasive ventilation in the setting of acute exacerbations of chronic obstructive pulmonary disease (COPD) has gained popularity, and is recommended by evidence-based guidelines. The evidence that it should be effective in chronic COPD is much weaker, and large, prospective, randomised, controlled studies that would also provide a guide for the selection of the best candidates, are still lacking. It has bee established, however, that home mechanical ventilation is certainly beneficial for a well-defined subgroup of patients. This includes the so called “blue bloater” patients (with hypercapnia and polyglobulia), other cases with increased hypercapnia, and patients with "overlapping" syndrome (COPD accompanied by sleep apnoe). Also, for patients with acute respiratory failure who refuse intratracheal intubation noninvasive mechanical ventilation remains the only choice. The past years have unequivocally proved the superiority of the positive pressure ventilation mode for either short term or long term use.]

[ACTINOMYCOSIS MIMICKING LUNG CANCER]

CSERNI Gábor, BORI Rita, BOROSS Gábor, FRANK Emil, LÓRÁND Katalin, SERÉNYI Péter, LENGYEL Mária, KOVÁCS Károly, HALÁSZ Mátyás

[INTRODUCTION - The mortality of lung cancer is high, but with early diagnosis the disease can often be cured. The differential diagnosis of pulmonary carcinoma is widely diverse. CASE REPORT - In a 53-year-old male patient, who had been successfully treated for pneumonia complicated with thoracic empyema, both a CT scan and bronchoscopy raised the suspicion of a malignant tumour. Brush cytology was inconclusive; it raised the possibility of malignancy but was not felt diagnostic of a malignant process, whereas biopsy revealed only inflammatory changes. After right lower lobectomy, actinomycosis was diagnosed by histology. This case is used in the paper as an opportunity to discuss the pseudotumorous presentation of thoracic actinomycosis. CONCLUSION - Pulmonary and thoracic actinomycosis is rare, but due to its ability to simulate tumours, it is an important disease to consider in the differential diagnosis of lung cancer.]

[THE POTENTIAL ROLE OF THE SEMICARBAZIDESENSITIVE AMINE OXIDASE ACTIVITY IN THE DEVELOPMENT OF DIABETIC RETINOPATHY]

DURA Eszter

[Recent data suggest that the copper-containing semicarbazide-sensitive amine oxidase enzyme (SSAO) may play a role in vascular endothelial damage through conversion of certain endogenous monoamines, such as methylamine, into cytotoxic aldehydes, hydrogen peroxide and ammonia. SSAO is present in various human tissues and in the serum. Elevated SSAO activities have been reported in patients with both types of diabetes mellitus. We have demonstrated that the activity of serum SSAO is significantly higher in type 2 diabetic patients with high-risk proliferative diabetic retinopathy compared to those without retinopathy. Our clinical results support the hypothesis that elevated SSAO activity may be involved in the pathogenesis of microvascular diabetic late complications, such as retinopathy. The enzymatic conversion of the endogenous monoamines (e.g. methylamine, aminoacetone) into toxic aldehydes and hydrogenperoxide may be one of the possible mechanisms of the development of microangiopathy. Also, the vascular adhesion protein-1 (VAP-1) function of the molecule can cause leukostasis and leukocyte activation through increased leukocyte adhesion, resulting in worsening of the capillary circulation and hypoxia. Further prospective, larger studies are needed to elucidate the role of the possible association between serum SSAO activity and highrisk proliferative retinopathy in patients with type 2 diabetes. The pharmacological manipulation of SSAO activity might be an interesting new concept for prevention and treatment of diabetic retinopathy.]

Fluoxetine use is associated with improved survival of patients with COVID-19 pneumonia: A retrospective case-control study

NÉMETH Klára Zsófia, SZÛCS Anna , VITRAI József , JUHÁSZ Dóra , NÉMETH Pál János , HOLLÓ András

We aimed to investigate the association between fluoxetine use and the survival of hospitalised coronavirus disease (COVID-19) pneumonia patients. This retrospective case-control study used data extracted from the medical records of adult patients hospitalised with moderate or severe COVID-19 pneumonia at the Uzsoki Teaching Hospital of the Semmelweis University in Budapest, Hungary between 17 March and 22 April 2021. As a part of standard medical treatment, patients received anti-COVID-19 therapies as favipiravir, remdesivir, baricitinib or a combination of these drugs; and 110 of them received 20 mg fluoxetine capsules once daily as an adjuvant medication. Multivariable logistic regression was used to evaluate the association between fluoxetine use and mortality. For excluding a fluoxetine-selection bias potentially influencing our results, we compared baseline prognostic markers in the two groups treated versus not treated with fluoxetine. Out of the 269 participants, 205 (76.2%) survived and 64 (23.8%) died between days 2 and 28 after hospitalisation. Greater age (OR [95% CI] 1.08 [1.05–1.11], p<0.001), radiographic severity based on chest X-ray (OR [95% CI] 2.03 [1.27–3.25], p=0.003) and higher score of shortened National Early Warning Score (sNEWS) (OR [95% CI] 1.20 [1.01-1.43], p=0.04) were associated with higher mortality. Fluoxetine use was associated with an important (70%) decrease of mortality (OR [95% CI] 0.33 [0.16–0.68], p=0.002) compared to the non-fluoxetine group. Age, gender, LDH, CRP, and D-dimer levels, sNEWS, Chest X-ray score did not show statistical difference between the fluoxetine and non-fluoxetine groups supporting the reliability of our finding. Provisional to confirmation in randomised controlled studies, fluoxetine may be a potent treatment increasing the survival for COVID-19 pneumonia.

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.

[Risk of nonsteroidal antiinflammatory drugs. Focus on aceclofenac]

FARSANG Csaba

[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used pharmaceuticals. Nevertheless, a number of studies emphasized that NSAIDs were damaging not only the gastrointestinal (GI), but also the cardiovascular (CV) system, could increase the blood pressure, the frequency of coronary events (angina, myocardial infarction) and stroke incidence, as well as they might deterio­rate renal functions. The National Institute for Health and Care Excellence (NICE) did not find evidence that administering NSAIDs could increase the risk of developing COVID-19 or worsened the condition of COVID-19 patients. However, unwanted effects of specific drugs differ substantially in their occurrence and seriousness as well. It seemed to be for a long time that the NSAIDs provoked higher GI-risk was closely related to the COX1/COX2 selectivity, like the cardiovascular (CV) risk to the COX2/COX1 selectivity, however, the recent data did not prove it clearly. Based on the available literature while pondering the gastrointestinal and cardiovascular adverse events, among all NSAIDs the aceclofenac profile seemed to be the most favourable.]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]

VÁLYI Péter

[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

BOCZÁN Judit, KLIVÉNYI Péter, KÁLMÁN Bernadette, SZÉLL Márta, KARCAGI Veronika, ZÁDORI Dénes, MOLNÁR Mária Judit

[Background – Spinal muscular atrophy (SMA) is an autosomal recessive, progressive neuromuscular disorder resulting in a loss of lower motoneurons. Recently, new disease-modifying treatments (two drugs for splicing modification of SMN2 and one for SMN1 gene replacement) have become available. Purpose – The new drugs change the progression of SMA with neonatal and childhood onset. Increasing amount of data are available about the effects of these drugs in adult patients with SMA. In this article, we summarize the available data of new SMA therapies in adult patients. Methods – Members of the Executive Committee of the Hungarian Clinical Neurogenetic Society surveyed the literature for palliative treatments, randomized controlled trials, and retrospective and prospective studies using disease modifying therapies in adult patients with SMA. Patients – We evaluated the outcomes of studies focused on treatments of adult patients mainly with SMA II and III. In this paper, we present our consensus statement in nine points covering palliative care, technical, medical and safety considerations, patient selection, and long-term monitoring of adult patients with SMA. This consensus statement aims to support the most efficient management of adult patients with SMA, and provides information about treatment efficacy and safety to be considered during personalized therapy. It also highlights open questions needed to be answered in future. Using this recommendation in clinical practice can result in optimization of therapy.]
