Összefoglaló. Újabb megfigyelések szerint a SARS-CoV-2-fertőzést követően gyermekekben a paediatric inflammatory multisystem syndrome (PIMS) elnevezésű, sokkállapottal szövődött Kawasaki-megbetegedéshez hasonlító, többszervi elégtelenségnek megfelelő tünetegyüttes alakulhat ki. A gyermekek többségében ilyenkor a direkt víruskimutatás már sikertelen, azonban a SARS-CoV-2 ellen képződött antitest igazolhatja a diagnózist. Dolgozatunk célja az egyik első hazai eset ismertetése. Egy 15 éves fiú került gyermek intenzív osztályos felvételre több napon át észlelt magas láz, kesztyű-, zokniszerű exanthema, conjunctivitis, többszervi elégtelenség, szeptikus sokk tüneteivel, akut gyulladásra utaló laboratóriumi eltérésekkel és diffúz hasi panaszokkal. Felvételét megelőzően néhány héttel SARS-CoV-2-fertőzésen esett át. Felvételekor a direkt víruskimutatás sikertelen volt, ám a SARS-CoV-2 elleni antitest vizsgálata pozitív lett. Komplex intenzív terápia mellett állapota stabilizálódott. Az irodalmi ajánlásoknak megfelelően immunglobulin-, acetilszalicilsav- és szteroidkezelésben részesítettük, melynek hatására állapota maradványtünetek nélkül rendeződött. A növekvő esetszámú gyermekkori SARS-CoV-2-fertőzés mellett egyre gyakrabban várható a SARS-CoV-2-fertőzést követő, a Kawasaki-betegség tüneteire emlékeztető PIMS kialakulása. Gyermekekben súlyos szeptikus állapot és többszervi elégtelenség esetén gondolni kell a PIMS lehetőségére, mely esetenként intenzív osztályos ellátást és célzott terápiát igényel. Legjobb tudomásunk szerint a leírásra került beteg a Magyarországon diagnosztizált egyik legkorábbi eset. Orv Hetil. 2021; 162(16): 602-607. Summary. Recently following SARS-CoV-2 infection, a new, multisystem disease (paediatric inflammatory multisystem syndrome, PIMS) with fever was recognized in children with shock and multiorgan failure. On of the first Hungarian cases will be described. A 15-year-old boy was admitted to the Paediatric Intensive Care Unit with persistent high fever, diffuse abdominal pain, septic shock, multiple organ failure, gloves- and socks-shaped cutan exanthema, conjunctivitis and laboratory signs of inflammation. Some weeks preceding his admission, symptoms of mild SARS-CoV-2 infection were revealed. At admission, the SARS-CoV-2 PCR and antigen tests were negative, however, the presence of IgG antibody was shown. Following complex supportive intensive care along with internationally recommended immunoglobulin, aspirin and steroid treatment, the patient was completely cured without any sequalae. In children after SARS-CoV-2 infection, PIMS could occur mimicking Kawasaki syndrome. At this time, in children virus PCR or antigen tests are usually negative already, but the presence of SARS-CoV-2 antibody could prove the preceding disease. Due to the increasing number of SARS-CoV-2 infections, the occurrence of post-SARS-CoV-2 PIMS in childhood is expected to increase. For paediatric patients, in case of severe septic state and multiple organ failure, PIMS should be also considered, which may require intensive care and targeted therapy. As far as we know, the described case is one of the earliest cases of PIMS in Hungary. Orv Hetil. 2021; 162(16): 602-607.

Infection by the new corona virus strain SARS-CoV-2 and its related syndrome COVID-19 has been associated with more than two million deaths worldwide. Patients of higher age and with preexisting chronic health conditions are at an increased risk of fatal disease outcome. However, detailed information on causes of death and the contribution of pre-existing health conditions to death yet is missing, which can be reliably established by autopsy only. We performed full body autopsies on 26 patients that had died after SARS-CoV-2 infection and COVID-19 at the Charité University Hospital Berlin, Germany, or at associated teaching hospitals. We systematically evaluated causes of death and pre-existing health conditions. Additionally, clinical records and death certificates were evaluated. We report findings on causes of death and comorbidities of 26 decedents that had clinically presented with severe COVID-19. We found that septic shock and multi organ failure was the most common immediate cause of death, often due to suppurative pulmonary infection. Respiratory failure due to diffuse alveolar damage presented as immediate cause of death in fewer cases. Several comorbidities, such as hypertension, ischemic heart disease, and obesity were present in the vast majority of patients. Our findings reveal that causes of death were directly related to COVID-19 in the majority of decedents, while they appear not to be an immediate result of preexisting health conditions and comorbidities. We therefore suggest that the majority of patients had died of COVID-19 with only contributory implications of preexisting health conditions to the mechanism of death.

Background: We sought to evaluate the effect of tocilizumab (TCB), a recombinant humanized monoclonal antibody against soluble interleukin-6 receptors, in patients hospitalized for coronavirus disease 2019 (COVID-19)., Methods: We included all patients with laboratory-confirmed COVID-19 who had completed hospitalization between March 10, 2020 and April 10, 2020 with follow-up through April 20, 2020. Patients who received TCB in addition to standard of care within 48 h of admission were matched in a 1:2 fashion to a similar cohort who received standard of care alone. Clinical outcomes were compared between matched groups. The primary outcome was de-escalation in oxygen therapy. Secondary outcomes were in-hospital death, septic shock, and acute kidney injury (AKI) requiring hemodialysis., Results: Out of 77 patients who received TCB in addition to standard of care, 34% (n = 26) received TCB within 48 h of admission. One-to-two propensity matching identified 20 versus 40 patients in the TCB and no-TCB treatment arms. In the TCB group, an improvement in oxygenation was observed in 80% (n = 16) of the patients by 7 days post TCB administration. After matching, there was no difference in clinical outcomes between TCB and no-TCB patients. In-hospital death: 10% versus 8%; p = .823, septic shock: 10% versus 11%, p = .912, AKI requiring hemodialysis (10% vs. 13%; p = .734)., Conclusions: Early treatment with TCB in patients admitted for COVID-19 led to an improvement in their oxygen status during hospitalization. This change however did not translate into improved survival when compared to a matched cohort with a similar clinical profile., (© 2020 Wiley Periodicals LLC.)

Background/aims: Coronavirus disease 2019 (COVID-19) can reportedly cause gastrointestinal symptoms. Therefore, we investigated the clinical characteristics of COVID-19 patients with diarrhea., Methods: We included 118 COVID-19 patients admitted to a single hospital from February 20 to March 31, 2020. Medical records with clinical characteristics, laboratory data, treatment course, and clinical outcomes were compared based on the presence or absence of diarrhea. Prognostic factors for disease severity and mortality in COVID-19 were also assessed., Results: Among patients, 54 (45.8%) had diarrhea, whereas seven (5.9%) had only diarrhea. The median age of patients with diarrhea was 59 years (44 to 64), and 22 (40.7%) were male. Systemic steroid use, intensive care unit admission, septic shock, and acute respiratory distress syndrome were less frequent in the diarrhea group than in the non-diarrhea group. No significant differences were observed in total hospital stay and mortality between groups. On multivariate analysis, age (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.01 to 1.12; p = 0.044), diabetes (OR, 3.00; 95% CI, 1.25 to 20.47; p = 0.042), and dyspnea (OR, 41.19; 95% CI, 6.60 to 823.16; p < 0.001) were independent risk factors for septic shock. On Cox regression analysis, diabetes (hazard ratio [HR], 4.82; 95% CI, 0.89 to 26.03; p = 0.043) and chronic obstructive pulmonary disease (HR, 16.58; 95% CI, 3.10 to 88.70; p = 0.044) were risk factors for mortality., Conclusion: Diarrhea was present in 45.8% of patients and was a common symptom of COVID-19. Although patients with diarrhea showed less severe clinical features, diarrhea was not associated with disease severity or mortality.

The pandemic caused by SARS-COV2 Virus/COVID-19, which was initially reported in China in December 2019, has become a major global health concern. COVID-19 can manifest with cytokine storm - an exaggerated systemic inflammatory phenomenon due to over-production of proinflammatory cytokines by immune cells that results in diffuse inflammatory lung disease and acute respiratory distress syndrome. It may be complicated by septic shock and subsequent multi-organ failure. Based on the most recently published evidence, this article will review and discuss comprehensive information on its clinical manifestations, laboratory tests, potential therapeutics, and prevention guidelines., (Copyright© South Dakota State Medical Association.)

The novel coronavirus (SARS-CoV-2) infection which has been known as Coronavirus diseases 2019 COVID-19 has become an endemic emergent situation by the World Health Organization. So far, no successful specific treatment has been found for this disease. As has been reported, most of non-survivor patients with COVID-19 (70%) had septic shock which was significantly higher than survived ones. Although the exact pathophysiology of septic shock in these patients is still unclear, it seems to be possible that part of it would be due to the administration of empiric antibiotics with inflammatory properties especially in the absence of bacterial infection. Herein, we have reviewed possible molecular pathways of septic shock in the patients who have received antibiotics with inflammatory properties which mainly is release of interleukin 1β (IL-1β), IL-6, and tumor necrosis factor α (TNF- α) through different routes. Altogether, we highly recommend clinicians to look after those antibiotics with anti-inflammatory activity for both empiric antibiotic therapy and reducing the inflammation to prevent septic shock in patients with diagnosed COVID-19., (Copyright © 2020 IMSS.

Autopsy investigation of a fatal case of rotavirus severe acute gastroenteritis and multiple organ failure in a 16-month boy with previous intrauterine growth retardation showed colocalization of nonstructural and structural rotavirus proteins within viroplasms in nephrons. This case brings new insights into extraintestinal rotavirus infection and new clues to its abilities to bind to human histo-blood group antigens.

Purpose: Hypercatecholaminemia-related heart failure has been proposed as the main cause of enterovirus A71-related (EV-A71) early mortality. The purpose of this study was to measure urine catecholamine concentrations in severe EV-A71-infected children. Methods: A total of 35 children, aged 2.5 ± 2.1 years, were divided into three groups. Group I: 15 septic shock patients, group II: 17 EV-A71-stage-2 patients, and group III: 3 EV-A71-stage-4 patients. The laboratory results, cardiac biomarkers and urine catecholamine concentrations were statistically analysed. Results: Group I had the highest C-reactive protein (CRP) levels and group II had the lowest B-type natriuretic peptide (BNP) and its N-terminal prohormone among the groups ( p  = 0.039, <0.01 and <0.01, respectively). Group III patients had significantly higher urine catecholamine and troponin-I values among the groups. If urine epinephrine (Epi) >134 ug/gCr, norepinephrine (NE) >176 ug/gCr and vanillylmandelic acid (VMA) >11.7 mg/gCr were used as the cutoff points to differentiate groups II and III, the sensitivities and specificity were all 100%. Conclusions: The significantly elevated urine catecholamine concentrations in EV-A71-stage-4 patients support the hypothesis that hypercatecholaminemia-related heart failure is involved in severe EV-A71 infection. Urine catecholamines could be used as reliable biomarkers for differentiation of severe EV-A71 infection with or without heart failure and septic shock.

Chikungunya is usually a benign disease, and little is known on the occurrence of severe clinical complications. We describe a 12-year-old boy with rapid onset septic shock and multi-organ failure associated with chikungunya fever. Severe sepsis and septic shock can be associated with chikungunya.

Long-term success of lung transplantation is limited by allograft dysfunction and frequent infections. Varicella zoster virus infection (VZV) is one of the most common opportunistic infections among solid organ transplantation recipients. However the occurrence of visceral involvement or disseminated disease, as seen after bone marrow transplantation, is rare. We report a case of a 59-year-old woman who underwent double-lung transplantation with a fatal visceral and disseminated varicella zoster virus infection., (© 2018 John Wiley & Sons A/S.

Epidemics of human parechovirus (HPeV) causing disease in young children have occurred every 2 years in Australia since 2013. HPeV genotype 3 caused the epidemic from late 2017 to early 2018. Most HPeV infections cause no or mild symptoms including gastroenteritis or influenza-like illness. Characteristically, young infants present with fever, irritability and on occasions a diffuse rash ("red, hot and angry" babies). Severe disease can manifest as meningoencephalitis, seizures or sepsis-like presentations (including septic shock), or less common presentations including signs of surgical abdomen. Testing for HPeV by specific molecular tests is indicated in children younger than 6 months of age with characteristic presentations without another confirmed diagnosis including febrile illnesses with other suggestive features (eg, rash, seizures), sepsis syndromes (including shock), and suspected meningoencephalitis (which may be detected by magnetic resonance imaging only). There are no effective antiviral therapies. Treatment is primarily supportive, including management of complications. Some infants with severe HPeV infection may have adverse neurodevelopment. Follow-up by a paediatrician is recommended.

20% of trauma deaths occur late after the injury. It is usually the result of sepsis, multi-system organ failure, or other complications. In Polytrauma induced sepsis and septic shock patients, antibacterial management is crucial. The knowledge of recent aspects of treatment is decreasing the costs and the resistance of pathogens, morbidity and mortality. Different models of treatment are suggested by authors, basically they are depended on: the patients age, there health condition, the factors of immunodeficiency, at the location of infection and others. Using the key words, the search engines produced articles. The review was made on the studies about Polytrauma induced sepsis and septic shock patients, about their antimicrobial treatment dosage and duration, about the source control and about the methods of early identification of pathogens (Bacteria and Candida). The advantages and disadvantages of early identification were also studied. Also the role if biomarkers were also reviewed. Based on the review, recommendations are given about the recent principles of antibacterial treatment of Polytrauma induced sepsis and septic shock patients.

Rationale: Hantaviruses cause two forms of diseases in humans, namely hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome. Hantavirus infections can occur in pregnant women, and could influence the maternal and fetal outcomes, although this is a rare finding, even in endemic areas., Patient Concerns: In this report, we describe anunusual case involving a pregnant woman with HFRS who was in a state of shock., Diagnoses: Hemorrhagic fever with renal syndrome and septic shock., Interventions: Timely termination of pregnancyalong with correction of the shock is very important to curb the inflammation and reduce organ damage., Outcomes: Although HFRS in pregnancy could pose a serious threat to the lives of the mother and the child. Our patient was successfully treated., Lessons: Early and accurate diagnosis, anti-shock treatment, and timely termination of pregnancyare the key aspects of therapy for HFRS with late pregnancy.

AbstractReported herein is the first case of Leishmania -human immunodeficiency virus (HIV) coinfection in Ecuador. In Ecuador, HIV infections overlap endemic areas of leishmaniasis. Immunosuppression is a well-established risk factor for developing severe disease. This is a severe case of a 32-year-old man presenting with disseminated pleomorphic ulcers, papules, and cutaneous plaque-like lesions over his whole body. Numerous amastigotes were observed in both skin scrapings and biopsies. The sequence of the cytochrome b gene confirmed the presence of Leishmania guyanensis . The patient was treated but failed to respond to meglumine antimoniate and amphotericin B. Six months later, the patient died due to bacterial septic shock.

Background: Recent pandemics of influenza A H1N1pdm09 virus have caused severe illness, especially in young people. Very few studies on influenza A H1N1pdm09 in post-pandemic periods exist, and there is no information on the severity of both seasonal influenza A(H1N1) and A(H3N2) from the same season, adjusting for potential confounders, including vaccine., Methods and Results: We performed a retrospective observational study of adults hospitalized during the 2014 season with influenza A(H1N1) or A(H3N2). All patients underwent the same diagnostic and therapeutic protocol in a single hospital, including early Oseltamivir therapy. We included 234 patients: 146 (62.4%) influenza A(H1N1) and 88 (37.6%) A(H3N2). A(H1N1) patients were younger (p<0.01), developed more pneumonia (p<0.01), respiratory complications (p = 0.015), ARDS (p = 0.047), and septic shock (p = 0.049), were more frequently admitted to the ICU (p = 0.022), required IMV (p = 0.049), and were less frequently vaccinated (p = 0.008). After adjusting for age, comorbidities, time from onset of illness, and vaccine status, influenza A(H1N1) (OR, 2.525), coinfection (OR, 2.821), and no vaccination (OR, 3.086) were independent risk factors for severe disease., Conclusions: Hospitalized patients with influenza A(H1N1) were more than twice as likely to have severe influenza. They were younger and most had not received the vaccine. Our findings suggest that seasonal influenza A(H1N1) maintains some features of pandemic viruses, and recommend wider use of vaccination in younger adult high-risk patients., Competing Interests: The authors have declared that no competing interests exist.

The objective of this study was to elucidate the causes of death and mortality in a cohort of inpatients infected with HIV. The causes of death and mortality were evaluated by using the clinical data of 1,076 patients admitted to the Center for Infectious Diseases, Beijing Ditan Hospital, between January 1, 2009, and November 30, 2012, and who were followed for 6 months after discharge. During the 4-year study period, 216 patients had died by the 6-month follow-up (mortality rate, 20.1%). Opportunistic infections were the most common causes of death (42.0%), followed by malignancies (23.1%), unexplained central nervous system infections and occupying lesions (18.1%), infectious shock (10.2%), severe hepatitis and decompensated cirrhosis (3.2%), sudden death (1.4%), lactic acidosis (0.9%), and uremia (0.9%). The strong risk factors for mortality were cost constraints and unaffordable further diagnosis and treatment (adjusted hazard ratio [AHR] = 134.394, 95% confidence interval [CI] = 25.748-701.481, p < .001), unexplained etiologies (AHR = 12.551, 95% CI = 6.642-23.716, p < .001), and multiple complications (AHR = 5.798, 95% CI = 2.973-11.308, p < .001). Mortality was not associated with CD4 levels or combined antiretroviral therapy (cART) in a cohort of inpatients at a special hospital for HIV/AIDS patients in China. AIDS-related infections and malignancies were the most common causes of death in patients infected with HIV, and improvement of the etiological diagnosis would help physicians provide appropriate treatment and reduce mortality rates.

During a 2014 outbreak, 450 patients with confirmed chikungunya virus infection were admitted to the University Hospital of Pointe-à-Pitre, Guadeloupe. Of these, 110 were nonpregnant adults; 42 had severe disease, and of those, 25 had severe sepsis or septic shock and 12 died. Severe sepsis may be a rare complication of chikungunya virus infection.

Introduction: A chikungunya outbreak took place in the State of Yucatan starting in the second half of 2015 OBJECTIVE: To analyse the clinical course of a case of chikungunya in a previously healthy infant, providing practical evidence to guide future diagnoses and treatment during outbreak seasons in endemic areas, Case Report: Clinical manifestation started with a sudden onset of fever and a diffuse macular-papillary erythema, originally treated in the community with non-steroidal anti-inflammatory drugs. Two days later, the fever relapsed with hypoactivity, severe thrombocytopenia and neutropenia (without lymphopenia), respiratory distress, liver dysfunction, sepsis, followed by septic shock with a fatal outcome. IgM test was positive to chikungunya, while her mother tested negative. Pseudomonas aeruginosa was isolated from the blood culture possible due to contamination, without ruling out the possibility of a mixed origin sepsis., Conclusions: Chikungunya is a disease in which the manifestations in neonates and young infants can be severe, and even fatal. It is important to suspect it in this age group at risk of vector contact, in the presence of fever without apparent source of infection and cutaneous manifestations. It is important to use the antipyretics cautiously, considering the possibility of aggravating the underlying infection, and the potential hepatic and haematological damage., (Copyright © 2016 Sociedad Chilena de Pediatría.
