RESUMO
Brucellar endocarditis is a rare entity commonly described as a severe disease associated with high mortality and generally requiring valve surgery for cure. Right-sided endocarditis, a very uncommon presentation of brucellosis, may be associated with a better prognosis. We describe the case of a 72-year-old woman admitted to our institution with a persistent fever and multiple pulmonary infiltrates. Transthoracic echocardiography and serologic tests led to the diagnosis of brucellar tricuspid endocarditis. The patient responded favorably to antibiotic treatment alone and did not need surgery. Prolonged antibiotic therapy with a combination of drugs active on intracellular microorganisms in the absence of surgical treatment could be effective in brucellar tricuspid endocarditis when the valve is not severely damaged.
RESUMO
Background: Among MDR bacteria, carbapenem-resistant Acinetobacter baumannii (CRAB) is a major concern due to the limited therapeutic options. During the COVID-19 pandemic, a worrying increase in the spread of CRAB infections was reported. Objectives: The study assessed the risk factors for CRAB bloodstream infection (BSI) in patients admitted to the ICU with CRAB colonization, and the related mortality risk factors. Methods: We conducted a single-centre, observational, prospective study; all consecutive patients with CRAB colonization admitted to the ICU of a tertiary hospital in Rome from January 2021 to September 2022 were included in the study. Univariate and multivariate analyses were performed to investigate BSI and mortality risk factors. Results: Overall, 129 patients were included in the study; 57 (44%) out of these developed BSI. In our study population, at the multivariable analysis the Charlson comorbidity index (CCI) (Pâ=â0.026), COVID-19 (Pâ<â0.001), multisite colonization (Pâ=â0.016) and the need for mechanical ventilation (Pâ=â0.024) were risk factors independently associated with BSI development. Furthermore, age (Pâ=â0.026), CCI (Pâ<â0.001), septic shock (P =â0.001) and Pitt score (Pâ<â0.001) were independently associated with mortality in the BSI patients. Instead, early appropriate therapy (Pâ=â0.002) and clinical improvement within 72â h (Pâ=â0.011) were shown to be protective factors. Conclusions: In critically ill patients colonized by CRAB, higher CCI, multisite colonization and the need for mechanical ventilation were identified as risk factors for BSI onset. These predictors could be useful to identify patients at highest risk of BSI.
RESUMO
Streptococcus intermedius is frequently associated with brain and liver abscesses, while pleuropulmonary infections are considered rarer. Even less frequent is the association of lung and brain abscesses due to this agent with infective endocarditis. We describe the case of a 40-year-old man complaining of cough, fever, and headache who was diagnosed with a brain abscess due to S. intermedius, a concomitant lung abscess, and aortic native valve endocarditis. He was treated with surgical drainage of the brain abscess and a 4-week course of intravenous ceftriaxone, followed by oral amoxicillin/clavulanate, obtaining healing of the lesions without relapse of the infection.
RESUMO
BACKGROUND AND OBJECTIVES: This retrospective study aims to disclose further early parameters of COVID-19 morbidity and mortality. METHODS: Three hundred and eighty-two COVID-19 patients, recruited between March and April 2020, were divided into three groups according to their outcome: (1) hospital ward group (patients who entered the hospital wards and survived); (2) intensive care unit (ICU) group (patients who attended the ICU and survived); (3) the deceased group (patients admitted to ICU with a fatal outcome). We investigated routine laboratory parameters such as albumin, glycemia, hemoglobin amylase, lipase, AST, ALT, GGT, LDH, CK, MGB, TnT-hs, IL-6, ferritin, CRP, PCT, WBC, RBC, PLT, PT, INR, APTT, FBG, and D-dimer. Blood withdrawal was carried out at the beginning of the hospitalization period. RESULTS: ANOVA and ROC data evidenced that the concomitant presence of alterations in albumin, lipase, AST, ALT, LDH, MGB, CK, IL-6, ferritin in women, CRP and D-dimer is an early sign of fatal outcomes. CONCLUSION: The present study confirms and extends the validity of routine laboratory biomarkers (i.e., lipase, AST, ALT, LDH, CK, IL-6, ferritin in women, CRP and D-dimer) as indicators of COVID-19 morbidity and mortality. Furthermore, the investigation suggests that both gross changes in albumin and MGB, markers of liver and heart damage, may early disclose COVID-19 fatal outcomes.

BACKGROUND: COVID-19 is a severe acute respiratory disease caused by SARS-CoV-2, a virus belonging to the Coronaviridae family. This disease has spread rapidly around the world and soon became an international public health emergency leading to an unpredicted pressure on the hospital emergency units. Early routine blood biomarkers could be key predicting factors of COVID-19 morbidity and mortality as suggested for C-reactive protein (CRP), IL-6, prothrombin and D-dimer. This study aims to identify other early routine blood biomarkers for COVID-19 severity prediction disclosed directly into the emergency section. METHODS: Our research was conducted on 156 COVID-19 patients hospitalized at the Sapienza University Hospital "Policlinico Umberto I" of Rome, Italy, between March 2020 and April 2020 during the paroxysm's initial phase of the pandemic. In this retrospective study, patients were divided into three groups according to their outcome: (1) emergency group (patients who entered the emergency room and were discharged shortly after because they did not show severe symptoms); (2) intensive care unit (ICU) group (patients who attended the ICU after admission to the emergency unit); (3) the deceased group (patients with a fatal outcome who attended the emergency and, afterward, the ICU units). Routine laboratory tests from medical records were collected when patients were admitted to the emergency unit. We focused on Aspartate transaminase (AST), Alanine transaminase (ALT), Lactate dehydrogenase (LDH), Creatine kinase (CK), Myoglobin (MGB), Ferritin, CRP, and D-dimer. RESULTS: As expected, ANOVA data show an age morbidity increase in both ICU and deceased groups compared with the emergency group. A main effect of morbidity was revealed by ANOVA for all the analyzed parameters with an elevation between the emergency group and the deceased group. Furthermore, a significant increase in LDH, Ferritin, CRP, and D-dimer was also observed between the ICU group and the emergency group and between the deceased group and ICU group. Receiver operating characteristic (ROC) analyses confirmed and extended these findings. CONCLUSIONS: This study suggests that the contemporaneous presence of high levels of LDH, Ferritin, and as expected, CRP, and D-dimer could be considered as potential predictors of COVID-19 severity and death.
RESUMO
Candida osteomyelitis is uncommon, especially after dog bites. We describe a case of a 63-year-old man without significant comorbidities presenting progressing swelling of the distal interphalangeal joint (DIJ) of right index finger following a dog bite. Despite empiric antibiotic therapy and local medications, there were no clinical signs of improvement. Clinical examination revealed fistula with purulent drainage on the volar region. Even though laboratory data showed inflammatory markers on range, magnetic resonance imaging (MRI) demonstrated signs of osteomyelitis. The patient was taken to exploration and debridement of the bite wound. Culture of the bone biopsy showed growth of Candida parapsilosis. Therefore, the patient was diagnosed with isolated fungal osteomyelitis and was initiated on fluconazole therapy. The treatment was effective and all symptoms were resolved in 8 weeks after the surgery. There were no signs of recurrence after 20 months of follow-up. The patient had no cosmetic abnormalities or sequelae. Concurrently with the description of the case report a review of the literature was provided. According to the authors, there are three main etiopathogenesis for this infection. The first pathogenic mechanism is direct inoculation into the deep tissues through the dog bite. The second hypothesis is direct translocation of the pathogen from the skin to the deep tissue and to the bone. The last mode of transmission is hematogenous dissemination. Fungal osteomyelitis are really rare conditions, especially after dog bites, but nevertheless it should be considered as a possible diagnosis when there is no response to antibiotics.

OBJECTIVES: Superinfections in patients hospitalized in intensive care unit (ICU) are an important and challenging complication, also in COVID-19. However, no definitive data are available about the role of multidrug-resistant Acinetobacter baumannii (MDR-AB) in COVID-19. METHODS: This was a single-center, cross-sectional study including patients with MDR-AB infections admitted to ICU with or without COVID-19, between January 2019 and January 2021. The primary objective of the study was to evaluate risk factor for MDR-AB infections in ICU patients hospitalized for COVID-19 or other etiology. The secondary endpoints were 30-days mortality in all study population and risk factors associated with development of bloodstream infection (BSI). RESULTS: During the study period 32 adults with COVID-19 were enrolled and compared with 115 patients admitted in the same ICU for other reasons. We observed a total of 114 deaths, with a survival rate of 29.3%: 18.8% in COVID-19 and 32.2% in control group. Relative risk for MDR-AB infection in COVID-19 showed that serum lactate levels mmol/l > 2, Acinetobacter baumannii colonization, BSI and steroid therapy were observed more frequently in COVID-19 patients. Cox regression analysis showed that serum lactate levels > 2 mmol/l, Acinetobacter baumannii colonization, BSI, and steroid therapy were associated with 30-days mortality. Finally, patients with COVID-19, white blood cells count > 11,000 mm3, serum lactate levels > 2 mmol/l, infections at time of ICU admission, Acinetobacter baumannii colonization, and steroid therapy were independently associated with development of BSI. CONCLUSIONS: Our data highlight the impact of BSI on outcome, the role of Acinetobacter baumannii colonization and the use of steroids on the risk to develop MDR-AB infections also during COVID-19.
