Aims of the study were to evaluate the impact of remdesivir on I) Intensive Care Unit (ICU) admission, II) need for orotracheal intubation (OTI) and III) in-hospital mortality. Furthermore, we estimated the kinetics of laboratory parameters and assessed the risk factors for in-hospital mortality in the remdesivir population.\u0000\u0000\u0000Methods\u0000We conducted a retrospective, single-center, case-control (1:1) study including hospitalized patients with confirmed SARS-CoV-2 infection. Cases were patients treated with remdesivir for 5 days, controls were patients not receiving remdesivir.\u0000\u0000\u0000Results\u0000A total of 192 patients (96 cases and 96 controls) were included in the study. Patients receiving remdesivir had a lower rate of ICU admission and need for OTI than controls, whereas no difference between cases and controls were observed as for mortality rate. However, at multivariable analysis remdesivir was not associated with ICU admission neither with OTI. Instead, presence of haematological malignancies, lower duration of symptoms, higher severity of infection and low lymphocytes count at admission were independently associated with in-hospital mortality. In patients treated with remdesivir a low albumin value and duration of lymphopenia were significantly associated with mortality.\u0000\u0000\u0000Conclusions\u0000Our real-life study showed that therapy with remdesivir did not have impact on either ICU admission, need for OTI or in-hospital mortality.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":"22 1","pages":"211-222"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75187140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the frequency of gonococcal and non-gonococcal genital infections in women referred to clinics in Ilam, Iran. Two swab samples were taken from each patient using a sterile swab, one swab was placed in a THB medium for the culture of Streptococcus agalactiae and the other in PBS buffer for PCR. PCR method was conducted for the identification of the other bacterial agents such as Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum, and also S. agalactiae. Sampling was performed on 169 women with symptomatic vaginosis. The frequency of S. agalactiae by culture and PCR methods was 4.7% (8 samples) and 13.6% (23 samples) respectively. Also, 6.5% (11 samples), 3.5% (6 samples), 4.1% (7 samples), 1.2% (2 samples), and 0% of the samples were positive for N. gonorrhoeae, M. genitalium, M. hominis, U. urealyticum and C. trachomatis by PCR method. Except for a significant association between S. agalactiae colonization and abortion, there was no significant correlation between the prevalence of these bacteria and the patient's age, age of marriage, number of deliveries, and number of abortions. Overall, the prevalence of gonococcal and non-gonococcal infection in women referred to clinics in Ilam is similar to the other parts of Iran.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":"23 1","pages":"247-253"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78234265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To determine the predictors of lethality, a retrospective study of 97 medical records of patients with leptospirosis in the period from 2009 to 2018 was conducted. Quantitative variables in the presence of normal distribution were compared using a paired Student's t-test, and in the case of an abnormal distribution, the Mann-Whitney U test was used. The criterion χ2 was used for qualitative variables. Multivariate analysis was used for the calculation of the Odds ratio. The following factors that are associated with death from leptospirosis have been identified: total bilirubin greater than 300 mcmol/L (OR, 4.25; 95% confidence interval [CI], 1.57-11.53), platelets less than 50 × (109/L) (OR, 3.95; 95% confidence interval [CI], 1.45-10.73), creatinine above 200 mcmol/L (OR, 1.95; 95% confidence interval [CI], 1.47-2.60) and jaundice (OR, 1.39; 95% confidence interval [CI], 1.21-1.60). Detection of these predictors will help to quickly identify a patient at risk of severe course of the disease and death, which will allow deciding on the use of early intensive care.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":"28 1","pages":"272-276"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90376718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The detailed knowledge of the HDV replication cycle and its interaction with HBV allowed the introduction of new drugs which are currently in phase II or III of experimentation. Basically, bulevirtide, to date the only one approved by EMA, inhibits the entry of the virus into the hepatocytes and hence its intrahepatic spread; lonafarnib inhibits the pharnesylation process of the L-HDAg, which is critical for the assembly of the HDV virion; the nucleic acid polymers (NAPs) mainly block the production/release of HBsAg.

Less frequently nocardiosis can interest immunocompetent population, causing especially primary cutaneous infections. Cutaneous involvement by Nocardia spp. may occur mostly as one of four clinical manifestations: superficial cellulitis or abscess, mycetoma, lymphocutaneous (also defined \"sporotrichoid\") infection and secondary cutaneous involvement from systemic disease. Infections usually present after minor local injury, especially in traumatic outdoor activities (e.g. gardeners, farmers, road accidents), with subsequent environmental contamination of the wound. In sporadic cases cutaneous infection follows an insect bite. Microbiological diagnosis is often difficult to obtain and N. brasiliensis is the species isolated in most cases (80%). We present the case of a 45-year-old female with fever and a painful and necrotizing lesion on her right leg with secondary ascending lesions occurred on the homolateral knee and consensual groin lymphadenopathy after insect sting (maybe a spider bite). Cultures on skin biopsy identified Nocardia brasiliensis. Infection was completely healed after 5 months of targeted antibiotic therapy. In addition, we performed a literature review of all cutaneous nocardiosis cases in immunocompetent individuals, finding that only in 22 cases the infection presented after insect bite; in most of these cases lymphocutaneous manifestation was seen and N. brasiliensis was the Nocardia species isolated. Our case, along with others in literature, reveals that the real burden of soft-tissues nocardiosis seems low but probably many cases might go undiagnosed because of difficulties in microbiology diagnosis. Primary cutaneous nocardiosis should be included in the diagnostic pathway in cases of cellulitis following insect bite or sting, especially when localized to extremities.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":"4 1","pages":"285-292"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90587998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this regard, microbial bioactive compounds with characteristics such as optimal compatibility and close interaction with the host immune system are considered a novel therapeutic approach. The fermentation process is one of the most well-known pathways involved in the natural synthesis of a diverse range of postbiotics. However, some postbiotics are a type of probiotic response behavior to environmental stimuli that usually play well-known biological roles. Also, postbiotics with unique structure and function are key mediators between intestinal microbiota and host cellular processes/metabolic pathways that play a significant role in maintaining homeostasis. By further understanding the nature of parent microbial cells, factors affecting their metabolic pathways, and the development of compatible extraction and identification methods, it is possible to achieve certain formulations of postbiotics with special efficiencies, which in turn will significantly improve the performance of health systems (especially in developing countries) toward a wide range of acute/chronic diseases. The present review aims to describe the fundamental role of postbiotics as the key mediators of the microbiota-host interactions. Besides, it presents the available current evidence regarding the interaction between postbiotics and host cells through potential cell receptors, stimulation/improvement of immune system function, and the enhancement of the composition and function of the human microbiome.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":"23 1","pages":"180-193"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79977643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of economic activities for the production, exploitation and export of agricultural products, minerals and raw materials demanded in the international market, favored the necessary conditions for the emergence, expansion, resurgence and persistence of the endemic epidemic of malaria in the different stages studied. A common and fundamental element in the different defined historical moments was the importance given to malaria as an economic problem due to the negative externalities it imposed on the labor force. In addition, due to the role it played as a barrier that limited the exploitation of natural resources and raw materials of interest; as well as the impact that it caused to the flow and commercial exchange. The previous situation was framed with the growth, consolidation and geostrategic expansion of the United States, as the main commercial partner of the region, and its interest in the exploitation of resources and raw materials, cheap labor, the need to create new markets, which coincided with the goals of modernization and economic strengthening of Colombia. Taking into account different relevant milestones that occurred in the 1848-2019 period, the following stages were defined: Epidemiological emergence and re-emergence of tropical fevers in places of economic exploitation, 1848-1899;Emergence of a new paradigm, control in enclaves of economic interest, ports and cities, 1900-1949;Control to eradication, intensified control-eradication, prevention and control, 1950-1999;Prevention, control and elimination of malaria, 2000-2019. Historically, antimalarial control initiatives in the country have been directed, restricted and prioritized in places of political and economic importance. The technical-scientific intervention measures implemented in the different stages studied have been uncritically replicated without adapting to the epidemiological scenarios existing in the country. Finally, the antimalarial control measures implemented in Colombia have been imported and adopted from international health initiatives as a result of commitments and obligations acquired in the global commercial context.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":"5 1","pages":"309-319"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88433317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
