RESUMEN

BACKGROUND: During the COVID pandemic, research has shown an increase in candidemia cases following severe COVID infection and the identification of risk factors associated with candidemia. However, there is a lack of studies that specifically explore clinical outcomes and mortality rates related to candidemia after COVID infection. OBJECTIVES: The aim of this international study was to evaluate the clinical outcomes and identify factors influencing mortality in patients who developed candidemia during their COVID infection. PATIENTS/METHODS: This study included adult patients (18 years of age or older) admitted to the intensive care unit (ICU) and diagnosed with COVID-associated candidemia (CAC). The research was conducted through ID-IRI network and in collaboration with 34 medical centres across 18 countries retrospectively, spanning from the beginning of the COVID pandemic until December 2021. RESULTS: A total of 293 patients diagnosed with CAC were included. The median age of the patients was 67, and 63% of them were male. The most common Candida species detected was C. albicans. The crude 30-day mortality rate was recorded at 62.4%. The logistic regression analysis identified several factors significantly impacting mortality, including age (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.02-1.07, p < .0005), SOFA score (OR 1.307, 95% CI 1.17-1.45, p < .0005), invasive mechanical ventilation (OR 7.95, 95% CI 1.44-43.83, p < .017) and duration of mechanical ventilation (OR 0.98, 95% CI 0.96-0.99, p < .020). CONCLUSIONS: By recognising these prognostic factors, medical professionals can customise their treatment approaches to offer more targeted care, leading to improved patient outcomes and higher survival rates for individuals with COVID-associated candidemia.

RESUMEN

In peritoneal dialysis (PD), a cloudy dialysate is an alarming finding. Bacterial peritonitis is the most common cause, however, atypical infections and non-infectious causes must be considered. A 46-year-old man presented with asthenia, paraesthesia, foamy urine and hypertension. Laboratory testing revealed severe azotaemia, anaemia, hyperkalaemia and nephrotic-range proteinuria. Haemodialysis was started through a central venous catheter. Later, due to patient preference, a Tenckhoff catheter was inserted. Conversion to PD occurred 3 weeks later, during hospitalization for a presumed central line infection. A month later, the patient was hospitalized for neutropenic fever. He was diagnosed an acute parvovirus infection and was discharged under isoniazid for latent tuberculosis. Four months later, the patient presented with fever and a cloudy effluent. Peritoneal fluid (PF) cytology was suggestive of infectious peritonitis, but the symptoms persisted despite antibiotic therapy. Bacterial and mycological cultures were negative. No neoplastic cells were detected. Mycobacterium tuberculosis eventually grew in PF cultures, despite previous negative molecular tests. Directed therapy was then initiated with excellent response. Thus, facing a cloudy effluent, one must consider multiple aetiologies. Diagnosis of peritoneal tuberculosis is hampered by the lack of highly sensitive and specific exams. Here, diagnosis was only possible due to positive mycobacterial cultures.

RESUMEN

Predictions of mortality may help in the selection of patients who benefit from intensive care. Endothelial dysfunction is partially responsible for many of the organic dysfunctions in critical illness. Reactive hyperaemia is a vascular response of the endothelium that can be measured by peripheral arterial tonometry (RH-PAT). We aimed to assess if reactive hyperaemia is affected by critical illness and if it correlates with outcomes. Prospective study with a cohort of consecutive patients admitted to an Intensive Care Unit. RH-PAT was accessed on admission and on the 7th day after admission. Early and late survivors were compared to non-survivors. The effect of RH-PAT variation on late mortality was studied by a logistic regression model. The association between RH-PAT and severity scores and biomarkers of organic dysfunction was investigated by multivariate analysis. 86 patients were enrolled. Mean ln(RHI) on admission was 0.580 and was significantly lower in patients with higher severity scores (p < 0.01) and early non-survivors (0.388; p = 0.027). The model for prediction of early-mortality estimated that each 0.1 decrease in ln(RHI) increased the odds for mortality by 13%. In 39 patients, a 2nd RH-PAT measurement was performed on the 7th day. The variation of ln(RHI) was significantly different between non-survivors and survivors (- 24.2% vs. 63.9%, p = 0.026). Ln(RHI) was significantly lower in patients with renal and cardiovascular dysfunction (p < 0.01). RH-PAT is correlated with disease severity and seems to be an independent marker of early mortality, cardiovascular and renal dysfunctions. RH-PAT variation predicts late mortality. There appears to be an RH-PAT impairment in the acute phase of severe diseases that may be reversible and associated with better outcomes.

RESUMEN

Infective endocarditis is a growing problem with many shifts due to ever-increasing comorbid illnesses, invasive procedures, and increase in the elderly. We performed this multinational study to depict definite infective endocarditis. Adult patients with definite endocarditis hospitalized between January 1, 2015, and October 1, 2018, were included from 41 hospitals in 13 countries. We included microbiological features, types and severity of the disease, complications, but excluded therapeutic parameters. A total of 867 patients were included. A total of 631 (72.8%) patients had native valve endocarditis (NVE), 214 (24.7%) patients had prosthetic valve endocarditis (PVE), 21 (2.4%) patients had pacemaker lead endocarditis, and 1 patient had catheter port endocarditis. Eighteen percent of NVE patients were hospital-acquired. PVE patients were classified as early-onset in 24.9%. A total of 385 (44.4%) patients had major embolic events, most frequently to the brain (n = 227, 26.3%). Blood cultures yielded pathogens in 766 (88.4%). In 101 (11.6%) patients, blood cultures were negative. Molecular testing of vegetations disclosed pathogens in 65 cases. Overall, 795 (91.7%) endocarditis patients had any identified pathogen. Leading pathogens (Staphylococcus aureus (n = 267, 33.6%), Streptococcus viridans (n = 149, 18.7%), enterococci (n = 128, 16.1%), coagulase-negative staphylococci (n = 92, 11.6%)) displayed substantial resistance profiles. A total of 132 (15.2%) patients had cardiac abscesses; 693 (79.9%) patients had left-sided endocarditis. Aortic (n = 394, 45.4%) and mitral valves (n = 369, 42.5%) were most frequently involved. Mortality was more common in PVE than NVE (NVE (n = 101, 16%), PVE (n = 49, 22.9%), p = 0.042).

RESUMEN

We present the case of a male patient not vaccinated against hepatitis B virus (HBV) and with reactivity to a surface antibody who, after immunosuppression for a multiple myeloma, had HBV reactivation. Pharmacological HBV suppression was tried, but viremia could not be suppressed. Production-detection core mutations or immunity issues can explain this clinical phenomenon.

RESUMEN

The increasing number of travellers to and from areas where considerable overlap between high malaria transmission and elevated prevalence of human immunodeficiency virus (HIV) infection exists, augment the probability that returning travellers to non-endemic countries might present with both infections. The presence of such co-infection can increase the severity of malaria episodes and also can change the progression of HIV infection. This article describes three travellers returning from malaria-endemic areas that had simultaneous diagnosis of severe Plasmodium falciparum malaria and HIV infection. Despite the severe forms of malaria and HIV co-infection, all patients responded successfully to anti-malarial treatment. Malaria and HIV interact with one another, with HIV infection increasing parasite burden, clinical severity and risk of complications of malaria; malaria seems to create an immunological interaction favourable to HIV spread and replication, with impact in progression to AIDS. The presence of malaria and HIV co-infection also poses other challenges related to treatment response, level of care and possible interactions of drugs. The authors recommend that all patients with fever returning from malaria endemic areas should be screened both for malaria and HIV infection.

RESUMEN

OBJECTIVES: Studies on the use of intrathecal perfusion devices (IPD) are still limited and therefore the aim of this study is to access the infectious complications associated to these devices. MATERIALS AND METHODS: A retrospective analysis of 145 patients who had an IPD implanted at the Chronic Pain Unit of Hospital de São João over the last 20 years. Mean follow-up time was 7.24 years (range: 0.47-17.41 years). Intrathecal antispastic drug perfusion was used in 123 patients (84.8%) and intrathecal analgesia in 22 patients. RESULTS: A total of 19 (8.71%) infections involving the IPD were identified of which, 14 (6.4%) were surgical site infections (SSIs). Methicillin-sensitive Staphylococcus aureus was the most commonly isolated bacteria in this group. Superficial SSIs were treated with oral antibiotic treatment or local wound care, while in deep SSI the pump was removed. Meningitis was identified in 5 (2.3%) patients and was always preceded by deep surgical site infections, some of which were already being treated with intravenous antibiotics. Median time to meningitis development was 2.2 months (IQR 82.58 months), after the introduction of the pump. Pump removal with anti-biotherapy were the treatment of choice. One patient died of a septic shock with associated meningitis and urinary tract infection. CONCLUSIONS: As seen in this study, infectious complications following implantation of IPD are not uncommon and include a variety of microorganisms. Antibiotic therapy without pump removal may be enough for superficial surgical site infections, but our data suggests that pump removal is the treatment of choice for deep infections as the infection may proceed to meningitis.

RESUMEN

BACKGROUND: Most HIV infected patients will develop some sort of neurologic involvement of the disease throughout their lives, usually in advanced stages. Neurologic symptoms may occur in acute HIV infection but myelopathy in this setting is rare. Up until this date, only two cases of transverse myelitis as a manifestation of acute HIV infection have been reported in the literature. Therapeutic approach in these patients is not well defined. CASE PRESENTATION: A 35 year-old male Caucasian recently returned from the tropics presented to our hospital with urinary retention and acute paraparesis. After extensive diagnostic workup he was diagnosed with acute HIV infection presenting as transverse myelitis. Full neurologic recovery was observed without the use of anti-retroviral therapy. CONCLUSION: Acute spinal cord disorders are challenging, as they present a wide array of differential diagnosis and may lead to devastating sequelae. Timely and rigorous diagnostic workup is of the utmost importance when managing these cases. Clinicians should be aware of the protean manifestations of acute HIV infection, including central nervous system involvement, and have a low threshold for HIV screening.

RESUMEN

Background In complicated endovascular infections by methicillin-resistant Staphylococcus aureus (MRSA) or Staphylococcus epidermidis (MRSE), when first-line therapy with vancomycin (VAN) or daptomycin (DAP) fails, combination therapy with ceftaroline (CFT) and DAP has been shown to be a useful approach as salvage therapy for persistent MRSA bacteremia. Objectives This study aimed to describe experience with daptomycin and ceftaroline combination therapy in MRSE-complicated endovascular infections. Methods A single-center retrospective review of consecutive patients with MRSE-complicated endovascular infections treated with ≥72 hours of DAP+CFT at any time during the course of treatment, from January 1, 2016 to December 31, 2020, at Centro Hospitalar Universitário São João (CHUSJ), Porto, Portugal, was conducted. The exclusion criteria were known resistance to daptomycin or ceftaroline, total time of combination therapy <72 hours and loss to follow-up. Results We identified seven cases that matched our criteria: five endocarditis and two central venous catheter infections. Six patients switched to combination therapy due to treatment failure with first-line agents - three due to persistent bacteremia and three due to progression of infection despite negative blood cultures. Effective surgical source control took one to four weeks to occur. Three patients died during the treatment, one from progression of the disease and two due to another infection. Conclusions We consider the DAP+CFT combination therapy to be a valid and safe therapeutic choice in complicated patients, such as those with severe infection, poor functional status, and impossibility or delay of surgical source control. However, conclusions on the role of combination therapy should be careful due to the low number of patients and the several confounding factors.

RESUMEN

BACKGROUND: Patients treated with direct-acting antivirals for hepatitis C exhibit high cure rates and improved survival. However, there is limited knowledge on their long-term clinical evolution. AIMS: In this study, we aimed to analyse the risk of hepatocarcinoma and hepatic decompensation in patients treated with direct-acting antivirals. METHODS: We conducted a retrospective single-centre study of Portuguese patients with advanced fibrosis treated with direct-acting antiviral agents between 2015 and 2022 at a tertiary hospital. RESULTS: Out of 460 patients, 50 (10.9 %) developed hepatocarcinoma and 36 (7.8 %) experienced hepatic decompensation. The risk for hepatocarcinoma was higher in patients aged over 55 (HR 4.87, 95 % CI 2.34-10.13, p < 0.001), with signs of portal hypertension (HR 3.83, 95 % CI 2.05-7.13, p < 0.001) and arterial hypertension (HR 1.98, 95 % CI 1.09-3.58, p = 0.024). Alcohol consumption (HR 3.30, 95 % CI 1.22-8.94, p = 0.019), signs of portal hypertension (HR 4.56, 95 % CI 2.19-9.48, p < 0.001) and hepatocarcinoma (HR 3.47, 95 % CI 1.69-7.10, p < 0.001) increased the risk of hepatic decompensation. CONCLUSION: Our study found a high incidence of hepatocarcinoma and hepatic decompensation, along with high mortality, in patients with advanced fibrosis treated with direct-acting antivirals. We identified risk factors such as arterial hypertension, alcohol consumption, and signs of portal hypertension, highlighting their role in clinical management and patient monitoring.

RESUMEN

Tuberculosis (TB) is a global health threat, especially in HIV patients who may experience immune reconstitution inflammatory syndrome (IRIS) upon Mycobacterium tuberculosis infection. Diagnosing and defining IRIS in non-HIV patients remains challenging. A 63-year-old male with acute leukaemia underwent induction therapy with a regimen containing fludarabine. Febrile neutropenia led to further investigations, revealing non-cavitary pulmonary TB, prompting anti-tuberculosis therapy (ATT) alongside resumed leukaemia treatment with sorafenib. Persistent extra-pulmonary TB, specifically lymph node involvement, were observed and IRIS was suspected, evidenced by enlarged lymphadenopathies, scrofula, and skin lesions that developed during the 13-month course of ATT, with no recurrence after its cessation. This article explores a case of lymph node TB-associated paradoxical IRIS in a non-HIV leukaemia patient, revealing the intricate interplay between tuberculosis and haematological malignancies and emphasizing the lack of standardized diagnostic criteria and treatment consensus. Challenges in lymph node TB diagnosis and management highlight the need for tailored therapeutic approaches. The report explores the potential immunomodulatory effects of fludarabine and sorafenib, questioning their roles in TB-IRIS. This case illuminates TB-IRIS dynamics in non-HIV patients, urging further research and collaborative efforts to enhance understanding and outcomes. As medical complexities persist, personalized therapeutic approaches and advancements in TB-IRIS research are crucial.

RESUMEN

BACKGROUND: Severe malaria may be complicated by the acute respiratory distress syndrome (ARDS), which is associated with a high mortality. In the present report, a series of three cases of imported malaria complicated by refractory severe ARDS supported with extracorporeal membrane oxygenation (ECMO) is presented. METHODS: One female and two male adult patients (ages 39 to 53) were included. Two patients had Plasmodium falciparum infection and one patient had Plasmodium vivax and Plasmodium ovale co-infection. Anti-malarial therapy consisted in intravenous quinine (in two patients) and intravenous quinidine (in one patient), plus clindamycin or doxycycline. RESULTS: Despite lung protective ventilation, a conservative strategy of fluid management, corticosteroids (two patients), prone position (two patients) and inhaled nitric oxide (one patient), refractory severe ARDS supervened (PaO2 to FiO2 ratio 68) and venovenous ECMO was then initiated. In one patient, a bicaval dual-lumen cannula was inserted; in the two other patients, a two-site configuration was used. Two patients survived to hospital-discharge (duration of ECMO support: 8.5 days) and one patient died from nosocomial sepsis and multi-organ failure after 40 days of ECMO support. CONCLUSIONS: ECMO support allowed adequate oxygenation and correction of hypercapnia under lung protective ventilation, therefore reducing ventilator-induced lung injury. ECMO referral should be considered early in malaria complicated by severe ARDS refractory to conventional treatment.

RESUMEN

Intravesical instillation of bacillus Calmette-Guérin (BCG) is a crucial adjunctive therapy in the treatment of bladder carcinoma. Its systemic complications are rare but include disseminated Mycobacterium bovis (M. bovis) infections, the diagnosis of which is a challenging task that requires keen clinical awareness. We report the case of an adult male treated with BCG who presented with fever, nonspecific constitutional symptoms, hepatic cytolysis, and cholestasis. After a detailed workup, the diagnosis was made of disseminated M. bovis infection with hepatic, pulmonary, renal, and ureteral involvement. Prompt anti-tuberculosis treatment resulted in clinical and analytical improvement. This case highlights the importance of early recognition of this serious complication in patients with BCG exposure, as well as the difficulty in confirming the diagnosis for proper treatment.

RESUMEN

Mycobacterium marinum is a ubiquitous and opportunist agent that may cause infections related to water activities in humans. It causes mainly skin and soft tissue infections, and other forms of presentation are uncommon. A 27-year-old man presented to the Emergency Department of a tertiary hospital due to a cervical foreign-body sensation that evolved into right cervical swelling and consumption symptoms. He was a waiter on a cruise in the Douro river. Weeks after the initial presentation, the diagnosis of Mycobacterium marinum infection was made by positive nucleic acid amplification tests (NAAT) in tissues obtained by excisional biopsy of cervical adenopathy. Treatment with rifampicin and clarithromycin was started. The symptoms improved, and there was a decrease in the adenopathy number and size. Although Mycobacterium marinum adenitis as initial presentation of the disease is rare, the identification of the agent by NAAT and favorable response to treatment supported the diagnosis.

RESUMEN

Malaria is frequently associated with splenomegaly. However, spontaneous splenic rupture is a rare and life-threatening complication. It is mostly seen in acute infection in non-immune adults and Plasmodium vivax and Plasmodium falciparum have been associated with the majority of cases. We describe a case of splenic rupture in an adult with complicated malaria by Plasmodium falciparum in which a conservative approach was used.

RESUMEN

Cytomegalovirus (CMV) infection is a frequent complication after a solid organ transplant, and in 86% of the cases, CMV disease occurred during the first 6 months after transplantation. Invasive CMV infections may be present as ulcerative infections of the upper gastrointestinal tract with esophagitis, gastritis, and ulcerations of the duodenum and the small bowel; however, CMV infections of the pancreatobiliary system, especially papillitis, are rarely observed. We present a case report of a man who underwent a heart transplant 6 years before, with a clinical picture of duodenitis and a simultaneous pseudotumor of major duodenal papilla who developed signs of acute abdomen caused by gastrointestinal CMV infection, successfully treated with medical therapy with valganciclovir. There is an urgent need for developments in CMV and solid organ transplantation to stratify the risk of late-onset CMV disease.

RESUMEN

Tuberculosis is a disease with a significant global burden in terms of morbidity and mortality. It usually presents as a pulmonary disease but can occasionally have extrapulmonary presentations. Immunosuppressed people are at an increased risk of tuberculosis and more frequently have atypical manifestations of the disease. Cutaneous involvement is estimated to occur in only 2% of extrapulmonary presentations. We report a case of a heart transplant recipient with disseminated tuberculosis who initially presented with cutaneous manifestations in the form of multiple abscesses that were mistaken for a community-acquired bacterial infection. The diagnosis was made after positive nucleic acid amplification testing and cultures for Mycobacterium tuberculosis from the drainage of the abscesses. After initiating antituberculous treatment, the patient had 2 instances of immune reconstitution inflammatory syndrome. A combination of diminished immunosuppression due to discontinuation of mycophenolate mofetil in the setting of acute infection, rifampin drug interactions with cyclosporine, and the beginning of treatment of tuberculosis all contributed to this paradoxical worsening. The patient responded favorably to increased glucocorticoid therapy and showed no signs of treatment failure after 6 months of antituberculous therapy.

RESUMEN

BACKGROUND: To mitigate mortality among critically ill COVID-19 patients, both during their Intensive Care Unit (ICU) stay and following ICU discharge, it is crucial to measure its frequency, identify predictors and to establish an appropriate post-ICU follow-up strategy. METHODS: In this multicentre, prospective cohort study, we included 586 critically ill COVID-19 patients. RESULTS: We observed an overall ICU mortality of 20.1% [95%CI: 17.1% to 23.6%] (118/586) and an overall hospital mortality of 25.4% [95%CI: 22.1% to 29.1%] (149/586). For ICU survivors, 30 days (early) post-ICU mortality was 5.3% [95%CI: 3.6% to 7.8%] (25/468) and one-year (late) post-ICU mortality was 7.9% [95%CI: 5.8% to 10.8%] (37/468). Pre-existing conditions/comorbidities were identified as the main independent predictors of mortality after ICU discharge: hypertension and heart failure were independent predictors of early mortality; and hypertension, chronic kidney disease, chronic obstructive pulmonary disease and cancer were independent predictors of late mortality. CONCLUSION: Early and late post-ICU mortality exhibited an initial surge (in the first 30 days post-ICU) followed by a subsequent decline over time. Close monitoring of critically ill COVID-19 post-ICU survivors, especially those with pre-existing conditions, is crucial to prevent adverse outcomes, reduce mortality and to establish an appropriate follow-up strategy.

RESUMEN

BACKGROUND: In view of the close relationship of Portugal with African countries, particularly former Portuguese colonies, the diagnosis of malaria is not a rare thing. When a traveller returns ill from endemic areas, malaria should be the number one suspect. World Health Organization treatment guidelines recommend that adults with severe malaria should be admitted to an intensive care unit (ICU). METHODS: Severe cases of malaria in patients admitted to an ICU were reviewed retrospectively (1990-2011) and identification of variables associated with in-ICU mortality performed. Malaria prediction score (MPS), malaria score for adults (MSA), simplified acute physiology score (SAPSII) and a score based on WHO's malaria severe criteria were applied. Statistical analysis was performed using StataV12. RESULTS: Fifty nine patients were included in the study, all but three were adults; 47 (79,6%) were male; parasitaemia on admission, quantified in 48/59 (81.3%) patients, was equal or greater than 2% in 47 of them (97.9%); the most common complications were thrombocytopaenia in 54 (91.5%) patients, associated with disseminated intravascular coagulation (DIC) in seven (11.8%), renal failure in 31 (52.5%) patients, 18 of which (30.5%) oliguric, shock in 29 (49.1%) patients, liver dysfunction in 27 (45.7%) patients, acidaemia in 23 (38.9%) patients, cerebral dysfunction in 22 (37.2%) patients, 11 of whom with unrousable coma, pulmonary oedema/ARDS in 22 (37.2%) patients, hypoglycaemia in 18 (30.5%) patients; 29 (49.1%) patients presented five or more dysfunctions. The case fatality rate was 15.2%. Comparing the four scores, the SAPS II and the WHO score were the most sensitive to death prediction. In the univariate analysis, death was associated with the SAPS II score, cerebral malaria, acute renal and respiratory failure, DIC, spontaneous bleeding, acidosis and hypoglycaemia. Age, partial immunity to malaria, delay in malaria diagnosis and the level of parasitaemia were not associated with death in this cohort. CONCLUSION: Severe malaria cases should be continued monitored in the ICUs. SAPS II and the WHO score are good predictors of mortality in malaria patients, but other specific scores deserve to be studied prospectively.

RESUMEN

Septic shock is the most dreaded presentation of an infection, carrying a reserved prognosis. Appropriate antimicrobial therapy is therefore the mainstay of treatment, alongside organ support as needed. Legionnaires' disease is mainly due to Legionella pneumophila serogroup 1 but it can be caused by other serogroups and species not detected by the urinary antigen test. Anti-tumour necrosis factor α therapy may increase the risk of invasive fungal infection, which carry a poor prognosis. We present a challenging case of a septic shock due to Legionella pneumophila and Saprochaete clavata infections, with a review of the two infections presented.
