RESUMEN
OBJECTIVE: To evaluate clinical and epidemiological characteristics and clinical outcomes in patients hospitalized with decompensated heart failure (DHF), with a comparison between Chagas and non-Chagas disease. METHOD: This is a retrospective cohort study involving 136 patients consecutively admitted with DHF between January 1 and December 31, 2011, with the following outcomes: acute renal failure, cardiogenic shock, rehospitalization, and hospital death. Individuals aged ≥ 18 years with DHF were included while those with more than 10% of missing data regarding outcomes were excluded. Statistical analysis was performed using SPSS version 17.0. Chi-squared test was used to compare proportions. Student's T test was used to compare means. Kaplan-Meier and log-rank tests were used to compare rehospitalization rates between the two groups over time. RESULTS: Chagasic and non-chagasic patients were compared. The first had lower mean systolic blood pressure (111.8±18.4 versus 128.8±24.4, p<0.01), lower mean diastolic blood pressure (74.5±13.6 versus 82.0±15.2, p<0.01) and lower left ventricular ejection fraction (26.5±6.2 versus 41.5±18.9, p<0.01). In all, 20 patients with Chagas (50.1%) were rehospitalized, compared to 35 patients in the non-Chagas group (35.4%, p=0.04). Log rank test = 4.5 (p<0.01) showed that rehospitalization rates between the two groups over time (Kaplan-Meier curves) differed. CONCLUSION: Chagas disease was associated with lower systolic and diastolic blood pressure and lower left ventricular ejection fraction. The rehospitalization rate was higher in Chagas disease.

Resumo Objetivo: Avaliar características clínico-epidemiológicas e desfechos clínicos em pacientes internados por insuficiência cardíaca descompensada (ICD), estabelecendo uma comparação entre pacientes chagásicos e não chagásicos. Método: Trata-se de um estudo de coorte retrospectivo abrangendo 136 pacientes internados consecutivamente com ICD entre 1 de janeiro e 31 de dezembro de 2011, tendo como desfechos: lesão renal aguda, choque cardiogênico, reinternamento e óbito hospitalar. Foram incluídos indivíduos com idade ≥ 18 anos com ICD e excluídos aqueles com mais de 10% de dados faltantes em relação aos desfechos. Para a análise estatística, foi utilizado o SPSS® versão 17.0. Para a comparação entre proporções, foi utilizado o teste Qui-quadrado. O teste T de Student foi utilizado para comparar médias. Utilizamos as curvas de Kaplan-Meier e o teste do log rank para comparar as taxas de reinternações entre os dois grupos ao longo do tempo. Resultados: Na comparação entre chagásicos e não chagásicos, os primeiros apresentaram menor média de pressão arterial sistêmica (111,8±18,4 versus 128,8±24,4; p<0,01), menor média de pressão arterial diastólica (74,5±13,6 versus 82,0±15,2; p<0,01) e menor fração de ejeção do ventrículo esquerdo (26,5±6,2 versus 41,5±18,9; p<0,01). Um total de 20 chagásicos (50,1%) reinternaram contra 35 não chagásicos (35,4%; p=0,04). O teste do log rank = 4,5 (p<0,01) mostrou que as taxas de reinternações entre os dois grupos ao longo do tempo (curvas de Kaplan-Meier) diferiram. Conclusão: A doença de Chagas associou-se a menores valores de pressão arterial sistólica e diastólica, além de menor fração de ejeção do ventrículo esquerdo. A taxa de reinternamento foi maior em chagásicos.

Psoriasis is an autoimmune disease triggered by different conditions in genetically susceptible people. It is characterized by variable cutaneous manifestations including localized or disseminated pustules. Generalized pustular psoriasis (GPP) has two main clinical forms: von Zumbusch psoriasis, characterized by severe erythrodermia and scaling skin after the resolution of pustules, and the annular form. GPP may also present severe extracutaneous manifestations including pneumonitis, heart failure and hepatitis. Old reports showed a relationship between hypoparathyroidism and hypocalcemia as triggers for GPP highlighting the importance of adequate workup of the patient and possible therapeutic changes in acute situations. Here, we present a case of severe von Zumbusch psoriasis with life-threatening complications triggered by severe hypocalcemia secondary to hypoparathyroidism successfully treated with aggressive calcium reposition.
