RESUMO

Low levels of testosterone may lead to reduced diaphragm excursion and inspiratory time during COVID-19 infection. We report the case of a 38-year-old man with a positive result on a reverse transcriptase-polymerase chain reaction test for SARS-CoV-2, admitted to the intensive care unit with acute respiratory failure. After several days on mechanical ventilation and use of rescue therapies, during the weaning phase, the patient presented dyspnea associated with low diaphragm performance (diaphragm thickness fraction, amplitude, and the excursion-time index during inspiration were 37%, 1.7 cm, and 2.6 cm/s, respectively) by ultrasonography and reduced testosterone levels (total testosterone, bioavailable testosterone and sex hormone binding globulin (SHBG) levels were 9.3 ng/dL, 5.8 ng/dL, and 10.5 nmol/L, respectively). Testosterone was administered three times 2 weeks apart (testosterone undecanoate 1000 mg/4 mL intramuscularly). Diaphragm performance improved significantly (diaphragm thickness fraction, amplitude, and the excursion-time index during inspiration were 70%, 2.4 cm, and 3.0 cm/s, respectively) 45 and 75 days after the first dose of testosterone. No adverse events were observed, although monitoring was required after testosterone administration. Testosterone replacement therapy led to good diaphragm performance in a male patient with COVID-19. This should be interpreted with caution due to the exploratory nature of the study.

RESUMO

INTRODUCTION: Higher mortality for patients admitted to intensive care units (ICUs) during the weekends has been occasionally reported with conflicting results that could be related to organisational factors. We investigated the effects of ICU organisational and staffing patterns on the potential association between weekend admission and outcomes in critically ill patients. METHODS: We included 59 614 patients admitted to 78 ICUs participating during 2013. We defined 'weekend admission' as any ICU admission from Friday 19:00 until Monday 07:00. We assessed the association between weekend admission with hospital mortality using a mixed logistic regression model controlling for both patient-level (illness severity, age, comorbidities, performance status and admission type) and ICU-level (decrease in nurse/bed ratio on weekend, full-time intensivist coverage, use of checklists on weekends and number of institutional protocols) confounders. We performed secondary analyses in the subgroup of scheduled surgical admissions. RESULTS: A total of 41 894 patients (70.3%) were admitted on weekdays and 17 720 patients (29.7%) on weekends. In univariable analysis, weekend admitted patients had higher ICU (10.9% vs 9.0%, P<0.001) and hospital (16.5% vs 13.5%, P<0.001) mortality. After adjusting for confounders, weekend admission was not associated with higher hospital mortality (OR 1.05, 95% CI 0.99 to 1.12, P=0.095). However, a 'weekend effect' was still observed in scheduled surgical admissions, as well as in ICUs not using checklists during the weekends. For unscheduled admissions, no 'weekend effect' was observed regardless of ICU's characteristics. For scheduled surgical admissions, a 'weekend effect' was present only in ICUs with a low number of implemented protocols and those with a reduction in the nurse/bed ratio and not applying checklists during weekends. CONCLUSIONS: ICU organisational factors, such as decreased nurse-to-patient ratio, absence of checklists and fewer standardised protocols, may explain, in part, increases in mortality in patients admitted to the ICU mortality on weekends.

RESUMO

INTRODUCTION: Community-acquired pneumonia (CAP) requiring intensive care unit (ICU) admission remains a severe medical condition, presenting ICU mortality rates reaching 30%. The aim of this study was to assess the value of different patterns of C-reactive protein (CRP)-ratio response to antibiotic therapy in patients with severe CAP requiring ICU admission as an early maker of outcome. METHODS: In total, 191 patients with severe CAP were prospectively included and CRP was sampled every other day from D1 to D7 of antibiotic prescription. CRP-ratio was calculated in relation to D1 CRP concentration. Patients were classified according to an individual pattern of CRP-ratio response with the following criteria: fast response - when D5 CRP was less than or equal to 0.4 of D1 CRP concentration; slow response - when D5 CRP was > 0.4 and D7 less than or equal to 0.8 of D1 CRP concentration; nonresponse - when D7 CRP was > 0.8 of D1 CRP concentration. Comparison between ICU survivors and non-survivors was performed. RESULTS: CRP-ratio from D1 to D7 decreased faster in survivors than in non-survivors (p = 0.01). The ability of CRP-ratio by D5 to predict ICU outcome assessed by the area under the ROC curve was 0.73 (95% Confidence Interval, 0.64 - 0.82). By D5, a CRP concentration above 0.5 of the initial level was a marker of poor outcome (sensitivity 0.81, specificity 0.58, positive likelihood ratio 1.93, negative likelihood ratio 0.33). The time-dependent analysis of CRP-ratio of the three patterns (fast response n = 66; slow response n = 81; nonresponse n = 44) was significantly different between groups (p < 0.001). The ICU mortality rate was considerably different according to the patterns of CRP-ratio response: fast response 4.8%, slow response 17.3% and nonresponse 36.4% (p < 0.001). CONCLUSIONS: In severe CAP, sequential evaluation of CRP-ratio was useful in the early identification of patients with poor outcome. The evaluation of CRP-ratio pattern of response to antibiotics during the first week of therapy was useful in the recognition of the individual clinical evolution.

RESUMO

O tétano acidental, a despeito de ser uma doença prevenível por imunização, ainda é frequente nos países subdesenvolvidos e em desenvolvimento. Sua letalidade ainda é elevada e os estudos sobre a melhor forma de tratamento são escassos. Tendo em vista esta escassez e a importância clínica dessa doença, um grupo de especialistas reunidos pela Associação de Medicina Intensiva Brasileira (AMIB), desenvolveu recomendações baseadas na melhor evidencia disponível para o manejo do tétano no paciente necessitando cuidados intensivos. As recomendações incluem aspectos relativos à admissão do paciente tetânico na unidade de terapia intensiva, tratamento com imunoglobulinas, tratamento antibiótico, manejo da analgossedação e bloqueio neuromuscular, manejo da disautonomia e especificidades na ventilação mecânica e fisioterapia nesta população especial.


Although tetanus can be prevented by appropriate immunization, accidental tetanus continues to occur frequently in underdeveloped and developing countries. Tetanus mortality rates remain high in these areas, and studies regarding the best therapy for tetanus are scarce. Because of the paucity of data on accidental tetanus and the clinical relevance of this condition, the Associação de Medicina Intensiva Brasileira (AMIB) organized a group of experts to develop these guidelines, which are based on the best available evidence for the management of tetanus in patients requiring admission to the intensive care unit. The guidelines discuss the management of tetanus patients in the intensive care unit, including the use of immunoglobulin therapy, antibiotic therapy, management of analgesics, sedation and neuromuscular blockade, management of dysautonomia and specific issues related to mechanical ventilation and physiotherapy in this population.

A qualidade da assistência prestada influencia diretamente o prognóstico da doença. Estas recomendações apresentam o manejo das formas graves de dengue, incluindo o reconhecimento de sinais de alerta, o tratamento visando o pronto re-estabelecimento da euvolemia e a avaliação e cuidado das potenciais complicações, no intuito de reduzir a morbi-mortalidade de crianças e adultos infectados.


Dengue is the most common vector-borne viral infection worldwide. In Brazil, the incidence has increased with successive epidemics, and an increasing proportion of patients present with severe forms of the disease. The prognosis for these patients is directly influenced by the quality of medical care. These guidelines present the management of the severe forms of dengue, including the recognition of warning signs, the treatment for prompt re-establishment of euvolemia and the evaluation and appropriate care of potential complications, thus reducing morbidity and mortality of infected children and adults.

RESUMO

INTRODUCTION: Coagulation abnormalities are frequent in patients with severe infections. However, the predictive value of d-dimer and of the presence of associated coagulation derangements in severe community-acquired pneumonia (CAP) remains to be thoroughly evaluated. The aim of this study was to investigate the predictive value of coagulation parameters in patients with severe CAP admitted to the intensive care unit. METHODS: d-Dimer, antithrombin, International Society of Thrombosis and Hemostasis score, clinical variables, Sequential Organ Failure Assessment (SOFA), The Acute Physiology and Chronic Health Evaluation II (APACHE II) and the CURB-65 score were measured in the first 24 hours. Results are shown as median (25%-75% interquartile range). The main outcome measure was hospital mortality. RESULTS: Ninety patients with severe CAP admitted to the intensive care unit were evaluated. Overall hospital mortality was 15.5%. d-Dimer levels in nonsurvivors were higher than those in survivors. In the univariate analysis, d-dimer, SOFA, and APACHE II scores were predictors of death. The discriminative ability of d-dimer (area under receiver operating curve = 0.75 [95% confidence interval, 0.64-0.83]; best cutoff for d-dimer was 1798 ng/mL) for in-hospital mortality was comparable with APACHE II and SOFA and better than C-reactive protein. Moreover, the addition of d-dimer to APACHE II or SOFA score increased the discriminative ability of both scores (area under the receiver operating curve = 0.82 [0.72-0.89] and 0.84 [0.75-0.91], respectively). CONCLUSIONS: d-Dimer levels are good predictors of outcome in severe CAP and may augment the predictive ability of scoring systems as APACHE II and SOFA.

RESUMO

INTRODUCTION: Our aim was to evaluate the impact of corticosteroids on clinical course and outcomes of patients with severe community-acquired pneumonia (CAP) requiring invasive mechanical ventilation. METHODS: This was a cohort study of patients with severe CAP from 2 intensive care units in tertiary hospitals in Brazil and Portugal. RESULTS: A total of 111 patients were included (median age, 69 years; 56% men; 34% hospital mortality). Corticosteroids were prescribed in 61 (55%) patients. Main indications for their use were bronchospasm (52.5%) and septic shock (36%). Mortality rate of patients treated with and without corticosteroids was comparable (29.5% vs 32%, P = .837). No significant differences were observed on clinical course from day 1 to day 7 as assessed by the Sequential Organ Failure Assessment score (P = .95). Furthermore, C-reactive protein declined similarly in both groups (P = .147). In a multivariate analysis, mortality was associated with older age and higher Acute Physiology and Chronic Health Evaluation II score. CONCLUSIONS: In patients with severe CAP requiring invasive mechanical ventilation, adjunctive therapy with corticosteroids did not influence intensive care unit and hospital mortality. In addition, no changes were observed on weaning from vasopressors, on recovery from organ failure/dysfunction as assessed by the Sequential Organ Failure Assessment score, as well as on C-reactive protein course.

RESUMO

O objetivo da presente revisão foi avaliar o estado atual do conhecimento sobre doença terminal e cuidados paliativos em unidade de terapia intensiva. Identificar as questões-chave e sugerir uma agenda de pesquisa sobre essas questões. A Associação Brasileira de Medicina Intensiva organizou um fórum especifico para o debate de doenças terminais na unidade de terapia intensiva, onde participaram profissionais experientes em medicina intensiva. Esses profissionais foram subdivididos em 3 subgrupos, que discutiram: comunicação em unidade de terapia intensiva, decisões diante de um doente terminal e cuidados/ações paliativas na unidade de terapia intensiva. As informações e referências bibliográficas foram copiladas e trabalhadas através de um site de acesso restrito. Os trabalhos ocorreram em 12 horas quando foram realizadas discussões sistematizadas seguindo o método Delphi modificado. Foram elaboradas definições sobre a terminalidade. A adequada comunicação foi considerada de primordial importância para a condução do tratamento de um paciente terminal. Foram descritas barreiras de comunicação que devem ser evitadas sendo definidas técnicas para a boa comunicação. Foram também definidos os critérios para cuidados e ações paliativas nas unidades de terapia intensiva, sendo considerada fundamental a aceitação da morte, como um evento natural, e o respeito à autonomia e não maleficência do paciente. Considerou-se aconselhável a suspensão de medicamentos fúteis, que prolonguem o morrer e a adequação dos tratamentos não fúteis privilegiando o controle da dor e dos sintomas para o alívio do sofrimento dos pacientes com doença terminal. Para a prestação de cuidados paliativos a pacientes críticos e seus familiares, devem ser seguidos princípios e metas que visem o respeito às necessidades e anseios individuais. Os profissionais da unidade de terapia intensiva envolvidos com o tratamento desses pacientes são submetidos a grande estresse e tensão...


The objective of this review was to evaluate current knowledge regarding terminal illness and palliative care in the intensive care unit, to identify the major challenges involved and propose a research agenda on these issues The Brazilian Critical Care Association organized a specific forum on terminally ill patients, to which were invited experienced and skilled professionals on critical care. These professionals were divided in three groups: communication in the intensive care unit, the decision making process when faced with a terminally ill patient and palliative actions and care in the intensive care unit. Data and bibliographic references were stored in a restricted website. During a twelve hour meeting and following a modified Delphi methodology, the groups prepared the final document. Consensual definition regarding terminality was reached. Good communication was considered the cornerstone to define the best treatment for a terminally ill patient. Accordingly some communication barriers were described that should be avoided as well as some approaches that should be pursued. Criteria for palliative care and palliative action in the intensive care unit were defined. Acceptance of death as a natural event as well as respect for the patient's autonomy and the nonmaleficence principles were stressed. A recommendation was made to withdraw the futile treatment that prolongs the dying process and to elected analgesia and measures that alleviate suffering in terminally ill patients. To deliver palliative care to terminally ill patients and their relatives some principles and guides should be followed, respecting individual necessities and beliefs. The intensive care unit staff involved with the treatment of terminally ill patients is subject to stress and tension. Availability of a continuous education program on palliative care is desirable.

RESUMO

BACKGROUND: High cortisol levels are frequent in patients with severe infections. However, the predictive value of total cortisol and of the presence of critical illness-related corticosteroid insufficiency (CIRCI) in severe community-acquired pneumonia (CAP) remains to be thoroughly evaluated. The aim of this study was to investigate the predictive value of adrenal response in patients with severe CAP admitted to the ICU. METHODS: Baseline and postcorticotropin cortisol levels C-reactive protein (CRP), d-dimer, clinical variables, sequential organ failure assessment (SOFA), APACHE (acute physiology and chronic health evaluation) II, and CURB-65 (confusion, urea nitrogen, respiratory rate, BP, age > or = 65 years) scores were measured in the first 24 h. Results are shown as median (interquartile range [IQR]). The major outcome measure was hospital mortality. RESULTS: Seventy-two patients with severe CAP admitted to the ICU were evaluated. Baseline cortisol levels were 18.1 microg/dL (IQR, 14.4 to 26.7 microg/dL), and the difference between baseline and postcorticotropin cortisol after 250 microg of corticotropin was 19 microg/dL (IQR, 12.8 to 27 microg/dL). Baseline cortisol levels presented positive correlations with scores of disease severity, including CURB-65, APACHE II, and SOFA (p < 0.05). Cortisol levels in nonsurvivors were higher than in survivors. CIRCI was diagnosed in 29 patients (40.8%). In univariate analysis, baseline cortisol, CURB-65, and APACHE II were predictors of death. The discriminative ability of baseline cortisol (area under receiver operating characteristic curve, 0.77; 95% confidence interval, 0.65 to 0.90; best cutoff for cortisol, 25.7 microg/dL) for in-hospital mortality was better than APACHE II, CURB-65, SOFA, d-dimer, or CRP. CONCLUSIONS: Baseline cortisol levels are better predictors of severity and outcome in severe CAP than postcorticotropin cortisol or routinely measured laboratory parameters or scores as APACHE II, SOFA, and CURB-65.

RESUMO

INTRODUCTION: Adrenal failure (AF) is associated with increased mortality in septic patients. Nonetheless, there is no agreement regarding the best diagnostic criteria for AF. We compared the diagnosis of AF considering different baseline total cortisol cutoff values and Deltamax values after low (1 microg) and high (249 microg) doses of corticotropin, we analyzed the impact of serum albumin on AF identification and we correlated laboratorial AF with norepinephrine removal. METHODS: A prospective noninterventional study was performed in an intensive care unit from May 2002 to May 2005, including septic shock patients over 18 years old without previous steroid usage. After measurement of serum albumin and baseline total cortisol, the patients were sequentially submitted to 1 microg and 249 microg corticotropin tests with a 60-minute interval between doses. Post-stimuli cortisol levels were drawn 60 minutes after each test (cortisol 60 and cortisol 120). The cortisol 60 and cortisol 120 values minus baseline were called Deltamax1 and Deltamax249, respectively. Adrenal failure was defined as Deltamax249 < or = 9 microg/dl or baseline cortisol < or = 10 microg/dl. Other baseline cortisol cutoff values referred to as AF in other studies (< or =15, < or =20, < or =25 and < or =34 mug/dl) were compared with Deltamax249 < or = 9 microg/dl and serum albumin influence. Norepinephrine removal was compared with the baseline cortisol values and Deltamax249 values. RESULTS: We enrolled 102 patients (43 male). AF was diagnosed in 22.5% (23/102). Patients with albumin < or =2.5 g/dl presented a lower baseline total cortisol level (15.5 microg/dl vs 22.4 microg/dl, P = 0.04) and a higher frequency of baseline cortisol < or =25 microg/dl (84% vs 58.3%, P = 0.05) than those with albumin > 2.5 g/dl. The Deltamax249 levels and Deltamax249 < or = 9, however, were not affected by serum albumin (14.5 microg/dl vs 18.8 microg/dl, P = 0.48 and 24% vs 25%, P = 1.0). Baseline cortisol < or = 23.6 microg/dl was the most accurate diagnostic threshold to determine norepinephrine removal according to the receiver operating characteristic curve. CONCLUSION: AF was identified in 22.5% of the studied population. Since Deltamax249 < or = 9 microg/dl results were not affected by serum albumin and since the baseline serum total cortisol varied directly with albumin levels, we propose that Deltamax249 < or = 9 microg/dl, which means Deltamax after high corticotropin dose may be a better option for AF diagnosis whenever measurement of free cortisol is not available. Baseline cortisol < or =23.6 microg/dl was the best value for predicting norepinephrine removal in patients without corticosteroid treatment.

RESUMO

Um aumento na incidência de anormalidades no metabolismo ósseo-mineral (osteopenia/osteoporose) tem sido observado em pacientes com síndrome de imunodeficiência humana adquirida (SIDA). Relatamos dois casos de osteonecrose em pacientes com SIDA. Ambos os pacientes estavam recebendo terapia anti-retroviral de alta potência (HAART) e apresentavam um ou mais fatores de risco conhecidos para osteonecrose. Nós revisamos a literatura e discutimos a patogênese, diagnóstico, prevenção e tratamento desta patologia em pacientes com SIDA.

RESUMO

An increase in the incidence of abnormalities on bone and mineral metabolism (osteopenia/osteoporosis) and the development of osteonecrosis has been observed in patients with acquired immunodeficiency syndrome (AIDS). Two cases of osteonecrosis in patients with AIDS are reported. Both patients were receiving highly active antiretroviral therapy (HAART) and presented with one or more known risk factors for osteonecrosis. We review the literature and discuss the pathogenesis, diagnosis, prevention and treatment of this entity in patients with AIDS.

RESUMO

À medida que a sobrevida dos doentes com infecção pelo HIV aumenta, as complicações neurológicas tornam-se mais prevalentes. O reconhecimento imediato de algumas destas é muito importante visto que a demora do diagnóstico e do início do tratamento são fatores que pioram sua evolução. Descrevemos um caso de tuberculoma cerebral em paciente HIV positivo que vinha em profilaxia com isoniazida. A evolução desfavorável em vigência do tratamento para toxoplasmose e os achados liquóricos foram os indícios mais importantes de que as lesões cerebrais eram tuberculomas. Comparamos as lesões antes e após o tratamento para tuberculoses através da ressonância magnética nuclear, documentando sua melhora. Os autores revisam ainda as manifestações neurológicas focais da síndrome da imunodeficiência adquirida, enfocando principlamente a tuberculose cerebral. Concluímos que os tuberculomas cerebrais devem sempre ser lembrados naqueles pacientes com lesões encefálicas focais que não respondem adequadamente ao tratamento para toxoplasmose cerebral, tanto pela forte prevalência da tuberculose em nosso meio quanto pelas implicações prognósticas desfavoráveis se o diagnóstico e a terapêutica forem retardados.

RESUMO

A medida que a sobrevida dos doentes com infeccao pelo HIV aumentoa, as complicacoes neurologicas tornam-se mais prevalentes. O reconhecimento imediato de algumas destas e muito importante visto que a demora do diagnostico e do inicio do tratamento sao fatores que pioram sua evolucao. Descrevemos um caso de tuberculoma cerebral em paciente HIV positivo que vinha em profilaxia com isoniazida. A evolucao desfavoravel em vigencia do tratamento para toxoplamose e os achados liquoricos foram os indicios mais importantes de que as lesoes cerebrais eram tuberculomas. Comparamos as lesoes antes e apos o tratamento para tuberculose atraves da ressonancia magnetica nuclear, documentando sua melhora. Os autores revisam ainda as manifestacoes neurologicas focais da sindrome da imunodeficiencia adquirida, enfocando principalmente a tuberculose cerebral. Concluimos que os tuberculomas cerebrais devem sempre ser lembrados naqueles pacientes com lesoes encefalicas focais que nao respondem adequadamente ao tratamento para toxoplasmose cerebral, tanto pela forte prevalencia da tuberculose em nosso meio quanto pela implicacoes prognosticas desfavoraveis se o diagnostico e a terapeutica forem retardados.
