Abstract
Purpose
The goal of our review was to gather information on the most important community-acquired and hospital-acquired co-infections among coronavirus disease 2019 (COVID-19) patients, and to examine not only the effect of these co-infections on disease outcomes but also to identify the possible risk factors that predispose COVID-19 patients to co-infections.
Methods
Medline (PubMed) and Google Scholar were searched for relevant articles published between January 1st, 2020, and September 31st, 2021, on the topic of co-infections among COVID-19 patients.
Results
Among community-acquired and hospital-acquired co-infections, bacterial and fungal co-infections are equally frequent, followed by viral co-infections that affected a relatively smaller portion of patients. Overall, co-infections were more frequent in the hospital than at the community level. Risk factors for acquiring co-infections include male gender, longer length of hospital stay, presence of supportive treatment, such as ventilation, the admission to intensive care units, the administration of medications, such as steroids or antibiotics, and certain blood parameters, such as high C-reactive protein or lymphopenia. The presence of co-infections could aggravate the COVID-19 disease severity, prolong the healing time of patients, and lead to worse disease outcomes overall.
Conclusion
Co-infections may increase the mortality of COVID-19 patients, especially in the hospital setting. Paying closer attention to hygiene, adhering to diagnostic and therapeutic protocols, implementing antimicrobial stewardship programs could decrease the occurrence of co-infections and lead to improved outcomes for COVID-19 patients.
Absztrakt:
A metasztatikus kasztrációrezisztens prosztatarák kezelésére az elmúlt években számos új, különböző hatásmechanizmusú gyógyszeres kezelés vált elérhetővé. Ez a fejlődés a terápiás döntéshozatalt egyre nehezebbé teszi. Az újabb kezelésekkel szemben is megfigyelhető az alapvonali, a szerzett és a keresztrezisztencia jelensége is. Ezért tehát az elsődleges terápia helyes megválasztása mellett, az azt követő vonalakban alkalmazott kezelések sorrendje és alkalmazásuk ideje is optimalizálásra szorul. Az újabb kezelésekkel kapcsolatos rezisztenciamechanizmusok egyre nagyobb mértékben válnak ismertté. Ezzel a terápiatervezés az eddigi empirikus – főleg a kipróbálásra építő – irányából egyre inkább a racionális – az adott daganat molekuláris sajátságait is figyelembe vevő –, személyre szabott kezelés irányába mozdul el. Ebben az összefoglaló közleményben ismertetjük azokat a rezisztenciamechanizmusokat, amelyek a metasztatikus kasztrációrezisztens prosztatarák kezelésében leggyakrabban használt három gyógyszerrel – docetaxel, abirateron és enzalutamid – kapcsolatosak. Többek között áttekintést nyújtunk a MDR- (multidrogrezisztens) fehérjéken keresztül megvalósuló, az androgénreceptor-, a Wnt-, a p53-szignálút, valamint a DNS hibajavító mechanizmusában részt vevő gének (mint például a BRCA és ATM) sérüléseivel összefüggésben kialakuló és a neuroendokrin differenciáció által kiváltott rezisztenciamechanizmusokról.

Abstract
Introduction
Patients with chronic obstructive pulmonary disease (COPD) are a vulnerable group in terms of the outcome of coronavirus infection in relation to their disease or its treatment, with a higher risk of developing serious complications compared to the healthy population.
Aim
The aim of our summary study is to review the background and health outcomes of chronic obstructive pulmonary disease and COVID-19 infection in the presence of both diseases.
Methods
Review of national and international medical databases (PubMed, MEDLINE, and MOB) with keywords COPD, COVID-19, disease risk, cause, prevention, complications, and prognosis.
Results
Meta-analyses show that COPD is one of the most common underlying conditions in patients hospitalized for COVID-19. Such patients are five times more likely to develop a serious complication due to oxygen supply problems therefore they are more likely to be admitted to intensive care units, where they may require mechanical ventilation. In the case of underlying COPD, the usual care plan for COVID-19 infection should be followed, as well as all public health recommendations to minimize the risk of developing and transmitting COVID-19.
Conclusion
Coronavirus infection is especially dangerous for COPD patients, who are much more likely to become seriously ill, so increased surveillance, prevention, early detection, adequate treatment and rehabilitation of the disease group are of paramount importance.
Abstract
Purpose
The purpose of current review is to conduct a systematic overview of articles published between 2019 and 2021 on the relationship of comorbidities and mortality due to Coronavirus Disease 2019 (COVID-19) among the elderly population.
Methods
We conducted a systematic search on PubMed for articles published between 2019 and 2021 to identify any cohort and case-control studies that investigated the relationship of comorbidities and COVID-19 mortality among the elderly, defined as 60 years of age and above. Databases were searched independently by two authors. Disagreements were resolved by the inclusion of a third investigator. Reviews, systematic reviews, and meta-analyses were excluded from our systematic review.
Results
A total of 15 studies were selected for our systematic review. Of the included studies, 3 were case-control, 3 were prospective cohort studies and 9 were retrospective cohort studies. As for size, 10 studies were conducted on populations of <1000 participants, 3 ranging from 1001 to 10,000, and 2 on populations of >10,000 individuals. The included studies found that the presence of certain conditions, such as cardiovascular, respiratory, renal diseases, malignancies, diseases of the nervous system and diabetes are associated to increased mortality in populations that consisted of elderly patients.
Conclusion
Results of our systematic review suggest that comorbidities contribute to increased COVID-19 mortality among the elderly. The detrimental effect of comorbidities and advanced age on the immune response could lead to a more frequent occurrence of symptomatic and severe infections with COVID-19.
Ambuláns rehabilitációs programok COVID–19-betegek számára
Outpatient rehabilitation programs for COVID-19 patients
Összefoglaló. A COVID–19-fertőzésen átesett betegek közül többen elhúzódó panaszokról számolnak be a felépülést követően, sokaknál tartósan fennáll a köhögés, a nehézlégzés, a mellkasi fájdalom, a légszomj attól függetlenül, hogy enyhe vagy súlyosabb tüneteket okozott a koronavírus. A betegek erőtlennek érzik magukat, erős fáradtságérzetre panaszkodnak, míg mások gyomor-bél rendszeri panaszokra, fejfájásra, depresszióra, a szaglás- és ízérzékelés elvesztésére. Számtalan kutatás leírja, hogy a fertőzés még akár hónapokkal később is hatással lehet a tüdő működésére, és korábban egészséges tüdőn is látható a koronavírus-fertőzés a gyógyulás után három hónappal készült kontroll-mellkas-CT-leleten. Éppen ezért szükség van a fertőzés lezajlását követően tüdőgyógyászati kivizsgálásra, ha a betegnek elhúzódó panaszai vannak, vagy ha a betegség tüdőgyulladást okozott. Szükség van a jelenleg működő fekvőbeteg-légzőszervi rehabilitáció mellett a kezelés ambuláns kiterjesztésére is, melynek célja újabb kórházi ápolás nélkül a teljes gyógyulás elérése a betegeknél. A COVID–19-fertőzésen átesett betegeknél a komplex rehabilitáció hatására javul a terhelhetőség, az életminőség, javulnak a légzésfunkciós értékek, csökkennek a panaszok, javul a betegek fizikai és pszichikai állapota. Összefoglaló kutatásunk célja áttekinteni, hogy milyen COVID–19 ambuláns rehabilitációs programok indultak el a koronavírus-fertőzésen átesett betegek esetében nemzetközi és hazai színtereken.

Summary. Several patients with COVID-19 infection report prolonged complaints after recovery and many of them suffer from persistent cough, dyspnea, chest pain and shortness of breath regardless of whether the coronavirus caused mild or more severe symptoms. They complain of severe fatigue and weakness while others grizzle about gastrointestinal complaints, headache, depression, loss of sense of smell and taste. Numerous studies describe that the infection can affect lung function even in months and coronavirus infection can be detectable in previously healthy lungs by taking a control chest CT scan three months after recovery. Therefore, chest follow-up is required after the infection if the patient has prolonged complaints or if the disease has caused pneumonia. In addition to the currently operating inpatient respiratory rehabilitation, there is also a need for an outpatient extension of treatment to achieve complete recovery in patients without further hospitalization. For those patients who have had the COVID-19 infection complex rehabilitation can improve their workload, quality of life, improves their respiratory function values, reduces their complaints and also improves their physical and mental condition. The aim of our summary research is to review what COVID-19 outpatient rehabilitation programs have been initiated for patients who went through coronavirus infection on international and domestic scenes.
