Muscle depletion in cirrhotic patients assessed using computed tomography: a cross-sectional study

ABSTRACT BACKGROUND: Sarcopenia is a common complication in patients with cirrhosis and may lead to increased morbidity and mortality. OBJECTIVE: To investigate the prevalence of sarcopenia and its association with disease severity scores, among patients with cirrhosis. DESIGN AND SETTING: Observational and retrospective cohort study carried out in a tertiary-care hospital in southern Brazil. METHODS: This study was conducted among patients with chronic liver disease who were followed up at the gastroenterology and hepatology outpatient clinic of a tertiary-care hospital in southern Brazil and who underwent computed tomography scans of the abdomen through any indication. RESULTS: We included 83 patients in the study. In the population evaluated, there was a predominance of males (57.80%) and the mean age was 56 years. Hepatitis B or C virus was present in the genesis of the disease in 34.9% of the cases, followed by an etiology of alcohol abuse (30.1%). Sarcopenia was diagnosed in 41 (49.4%) of the patients when the cutoff point for cirrhotic patients was used. There was no significant correlation between the Child-Pugh and MELD severity scores and the occurrence of sarcopenia. CONCLUSION: Sarcopenia presents high prevalence among patients with chronic liver disease, without any association with predictors of severity.

Immune restoration in human immunodeficiency virus and hepatitis C virus coinfected patients after highly active antiretroviral therapy

OBJECTIVE: To evaluate the influence of hepatitis C virus on immunological and virological responses after highly active antiretroviral therapy initiation in human immunodeficiency virus/hepatitis C virus coinfected patients compared to monoinfected human immunodeficiency virus-infected patients. METHODS: The study enrolled 65 human immunodeficiency virus-1-infected subjects who initiated highly active antiretroviral therapy and attended follow-up visits over 48 weeks from 2008 to 2010. They were grouped based on hepatitis C virus-RNA results. Virological and immunological responses were monitored at baseline and at the end of weeks 12, 24, 36, and 48. RESULTS: There were 35 human immunodeficiency virus monoinfected and 30 human immunodeficiency virus/hepatitis C virus coinfected patients. In the present study human immunodeficiency virus/hepatitis C virus coinfection did not seem to influence CD4 Tlymphocytes recovery. There was no difference between the curves of CD4 T-lymphocytes raise of coinfected and monoinfected groups. CONCLUSION: This prospective study confirms that hepatitis C virus infection does not seem to be associated with impaired CD4 T-lymphocytes recovery after HAART.

Whipple's disease: rare disorder and late diagnosis / Doença de Whipple: patologia rara e de diagnóstico tardio

Whipple's disease is a rare systemic infectious disorder caused by the bacterium Tropheryma whipplei. We report the case of a 61-year-old male patient who presented to emergency room complaining of asthenia, arthralgia, anorexia, articular complaints intermittent diarrhea, and a 10-kg weight loss in one year. Laboratory tests showed the following results: Hb = 7.5 g/dL, albumin = 2.5 mg/dL, weight = 50.3 kg (BMI 17.4 kg/m²). Upper gastrointestinal endoscopy revealed areas of focal enanthema in the duodenum. An endoscopic biopsy was suggestive of Whipple's disease. Diagnosis was confirmed based on a positive serum polymerase chain reaction. Treatment was initiated with intravenous ceftriaxone followed by oral trimethoprim-sulfamethoxazole. After one year of treatment, the patient was asymptomatic, with Hb = 13.5 g/dL, serum albumin = 5.3 mg/dL, and weight = 70 kg (BMI 24.2 kg/m²). Whipple's disease should be considered a differential diagnosis in patients with prolonged constitutional and/or gastrointestinal symptoms. Appropriate antibiotic treatment improves the quality of life of patients.

Doença de Whipple é uma rara infecção sistêmica causada pelo Tropheryma whipplei. Caracteriza-se por fase prolongada de sintomas inespecíficos, levando longo período até o seu diagnóstico. Sem tratamento, pode ser grave e fatal, mas com antibioticoterapia tem ótima resposta clínica e laboratorial. Relatamos o caso de paciente masculino, 61 anos, internado por astenia, anorexia, diarréia intermitente e perda de 10 kg em um ano. Apresentava-se com hemoglobina (Hb) 7,5 g/dL, albumina de 2,5 mg/dL, peso 50,3 kg (IMC 17,4). Endoscopia digestiva alta com áreas de enantema focal da mucosa duodenal e biópsia compatível com doença de Whipple. O diagnóstico foi confirmado com PCR sérica positiva, sendo instituído tratamento com ceftriaxone seguido de sulfametoxazol-trimetropim. Após um ano de tratamento, encontrava-se assintomático, com Hb 13,5 g/dL, albumina sérica de 5,3 mg/dL e peso de 70 kg. Doença de Whipple deve fazer parte da lista de diagnósticos diferenciais em pacientes com sintomas constitucionais e/ou com queixas gastrointestinais com evolução prolongada. O tratamento antibiótico pode curar a infecção, recuperando a qualidade de vida do paciente.

Síndrome de Wellens / Wellens syndrome

A avaliação de dor torácica é prática de rotina em serviços de emergência. Embora seja queixa comum e com amplo diagnóstico diferencial. é na suspeita de síndrome coronariana aguda (SCA) que a preocupação é maior. Eletrocardiograma e dosagem de enzimas cardíacas são ferramentas importantes na investigação dos pacientes. mas. quando negativos. podem não identificar algumas doenças. Relatamos o caso de uma paciente com angina. cujos exames iniciais na emergência não apresentavam alterações sugestivas de cardiopatia isquêmica. Doença de conhecimento recente. a síndrome de Wellens consiste em uma variante da angina instável. que. quando não reconhecida. pode acarretar em significativa morbidade e mortalidade.

The assessment of chest pain is a routine in emergency health services. Although this is a common complaint with a broad differential diagnosis. the major concern is the possibility of acute coronary syndrome (ACS). Electrocardiography and cardiac enzyme levels are important tools in the investigation of these patients; however. negative results may actually be overlooking the identification of some conditions. We report the case of a female patient with angina. whose baseline tests in the emergency room were negative for changes suggestive of ischemic heart disease. The Wellens syndrome. a recently described disease. is a variant of unstable angina which. if not identified. may result in significant morbidity and mortality.

Hematoma de músculo iliopsoas na vigência de tratamento com varfarina / Iliopsoas muscle hematoma during treatment with warfarin / Hematoma de músculo iliopsoas en la vigencia de tratamiento con warfarina

A varfarina é droga amplamente utilizada na prevenção de fenômenos tromboembólicos e o conhecimento de seus efeitos adversos faz-se necessário para o acompanhamento dos pacientes. Embora o desenvolvimento de discrasias sanguíneas seja complicação potencial nesses pacientes, a ocorrência de sangramento retroperitoneal é rara. Este artigo discute o caso de um paciente que evoluiu com hematoma do músculo iliopsoas durante tratamento com a referida droga, pós-implante de prótese aórtica metálica, com quadro clínico envolvendo importantes diagnósticos diferenciais.

Warfarin is a widely used drug for the prevention of thromboembolic events. Knowledge of its adverse effects is necessary for patient follow-up. Although the development of blood dyscrasias is a potential complication in these patients, retroperitoneal bleeding is rare. This article reports the case of a patient who developed iliopsoas muscle hematoma during treatment with warfarin after implantation of a metallic prosthetic aortic valve. The clinical manifestations involved important differential diagnoses.

La warfarina es un fármaco ampliamente utilizado en la prevención de fenómenos tromboembólicos, y el conocimiento de sus efectos adversos se hace necesario para el seguimiento de los pacientes. Aunque el desarrollo de discrasias sanguíneas es la complicación potencial en estos pacientes, la ocurrencia de sangrado retroperitoneal es rara. Este artículo discute el caso de un paciente que evolucionó con hematoma del músculo ileopsoas durante tratamiento con el referido fármaco en el postimplante de prótesis mitral metálica, con cuadro clínico implicando importantes diagnósticos diferenciales.
