Abstract
INTRODUCTION Meningeal cryptococcosis (MC) is a frequent cause of meningoencephalitis in people living with HIV (PLHIV), leading to substantial morbidity (20-55%). Clinical characteristics, lethality and adverse prognostic factors in PLHIV with MC admitted to intensive care units (ICUs) are described. METHODS A retrospective observational study. Period from 11/21/2006 to 05/24/2023. It involved 154 adult PLHIV diagnosed with MC and admitted to ICUs. Percentages and absolute values were compared by Chi-Square or Fisher's test and medians by Mann-Whitney test. The association with mortality was assessed by logistic regression. SPSS 23.0 software was used. A p-value <0.05 was considered significant. RESULTS Patients who died and those who survived were comparable in age and sex (p>0.05). Univariate analysis showed that impaired functional and nutritional status, lack of previous highly active antiretroviral therapy, CD4 <100 cells, APACHE II ≥ 13 and a PLHIV prognostic score ≥ 8 points, requiring mechanical ventilation (MV), respiratory failure, renal failure, neurological dysfunction or sepsis could be associated (p<0.05) with mortality. Logistic regression established that impaired functional and nutritional status, a PLHIV prognostic score ≥ 8, need for MV and presence of sepsis would be independent variables associated with mortality. CONCLUSION The results indicate that altered functional and nutritional status, a PLHIV prognostic score ≥ 8 points, requiring MV and suffering sepsis on admission to the ICU are more frequent in deceased patients, and they could therefore serve as independent variables to predict a higher risk of mortality.

Abstract
Invasive aspergillosis (IA) is a serious disease with high mortality. There are several risk factors and in-hospital outbreaks related with construction have been described. An entity related to COVID-19 infection, known as COVID-19 associated pulmonary aspergillosis (CAPA), has recently appeared. Early and appropriate treatment is of paramount importance, especially in immunocompromised and critically ill patients. Diagnosis is based on recognition of predisposing factors, clinical signs, imaging, direct examination, culture, histopathology, and biomarkers such as galactomannan. The drug of choice is voriconazole, but alternative therapies must be taken into account given the increasing presence of resistant isolates.

Abstract
Monkey pox is a rare zoonotic disease. It was first described in humans in Africa in 1970. On July 23, 2022, in view of the increasing number of cases reported in several countries and territories, the World Health Organization (WHO) concluded that the global outbreak constitutes a public health emergency of international concern. In our country, the first case was reported on May 22, 2022 and up to November 22 of this year, 895 patients were reported. We describe here the first case registered in Argentina requiring intensive care, according to the Epidemiological Bulletin, 46th epidemiological week, National Ministry of Health. The patient was a 44-year-old man with acquired immunodeficiency syndrome and severe Monkeypox, who presented obstructive ventilatory failure due to airway compromise and extensive generalized lesions of the integument, genitalia and fauces. In conclusion, the case presented alerts about potential complications that may require critical care and risk the patient's life.

Abstract
Tetanus is an infectious disease caused by a ubiquitous bacterium Clostridium tetani, that synthesizes and releasesa potent neurotoxin under anaerobic conditions, which is responsible for the clinical manifestations. As it is found in soil contaminated with animal and human excreta, it is difficult to eradicate but it may be prevented by immunization. Immunization rate has decreased in the last years, especially during the COVID-19 pandemic. We report two cases of tetanus, attended during 2022. A 39-year-old man whose entry route was a gunshot wound and he was discharged from the intensive care unit (ICU) and a second case of an 83-year-old woman with unknown entry point, who died during her ICU stay. The cases reported highlight that it is a life-threatening disease, its diagnosis is mainly clinical and it should be in the algorithm of differential diagnoses. We emphasize about the prompt treatment administration or consultation to a specialized healthcare center. The importance of this presentation is to show the severity of the disease, whose assessment is mainly clinical and should not escape the algorithm of differential diagnoses, emphasizing that treatment should be instituted early or when in doubt consult a specialized center. In addition to this, it is important to check theimmunization rate in our country, especially during thepandemic, becauseit is a vaccine-preventable disease.

Abstract
The COVID-19 pandemic presented high mortality from its beginning, without effective treatment for seriously ill patients. Build on the experience in Argentine hemorrhagic fever with convalescent plasma, we incorporated 90 patients with COVID-19, of which 87 were evaluable, into a multicenter study. We collected 397 plasma donations from 278 convalescent donors. Patients received plasma with an IgG concentration of 0.7-0.8 (measured by Abbott chemiluminescence) for every 10 kg of body weight. Survival during the first 28 days was the primary objective; 77% were male, age 54 ± 15.6 y/o (range 27-85), body mass index 29.7 ± 4.4; hypertension 39% and diabetes 20.7%; 19.5% had an immunosuppressive condition, 23% were health workers. Plasma was administered to 55 (63%) on spontaneous breathing with oxygen supplementation (mainly oxygen mask with reservoir bag in 80%), and to 32 patients (37%) on mechanical ventilation. The 28-day survival rate was 80%; 91% in patients infused on spontaneous breathing and 63% in those on mechanical ventilation (p = 0.0002). There was a significant improvement in the WHO pneumonia clinical scale at 7 and 14 days, and in PaO2 / FiO2, ferritin and LDH, in the week post-infusion. We observed an episode of circulatory volume overload and a febrile reaction, both mild. Convalescent plasma infusions are feasible, safe, and potentially effective, especially before requiring mechanical ventilation. They are an attractive clinical option for treating severe forms of COVID-19 until other effective therapies become available.

Abstract
Intra-abdominal infections represent a group of intra and retroperitoneal processes, ranging from localized infections to complicated ones, sepsis and septic shock, associated with a significant mortality rate. They are the third most commonly identified cause of sepsis and the second cause of death in the intensive care unit. Although antimicrobial therapy must be started as soon as possible, especially in critically ill patients, the source control procedure is highly relevant. On account of the importance of this subject, members of the Argentine Society of Infectious Diseases (SADI) and intensive care specialists joined to develop recommendations on diagnosis, treatment, and prevention of intra-abdominal infections. The literature published within the last 10 years was reviewed and analyzed, in addition of expert opinions and local data. This statement provides a basic tool for diagnosis based on clinical and microbiological criteria, orientation on empirical antimicrobial therapy schemes according to source, acquisition place (community or healthcare associated infections), infection severity, treatment duration, importance of source control, and preventive measures aimed to reduce surgical site infection risk. Likewise, it provides a simple algorithm for diagnosis and treatment for use in clinical practice. The work reveals the concern about the management of intra-abdominal infections, establishing local guidelines to optimize diagnosis, treatment and prevention, with the aim of reducing morbidity, mortality, length of stay, costs and antimicrobial resistance.
