Cryptococcosis in Acquired Immunodeficiency Syndrome Patients Clinically Confirmed and/or Diagnosed at Necropsy in a Teaching Hospital in Brazil.

Cryptococcosis occurs in acquired immunodeficiency syndrome (AIDS) patients with poor compliance to antiretroviral therapy or unaware of their human immunodeficiency virus status who present severe immunosuppression at admission. Consequently, high mortality rates are observed due to disseminated fungal infection. This report presents clinical and postmortem data of AIDS patients with cryptococcosis in a teaching hospital in Brazil. Retrospectively, medical and necropsy records of AIDS patients with cryptococcosis clinically confirmed and/or postmortem verified were reviewed. Clinical data were compared with those of patients presenting a good outcome to evaluate disseminated fungal infection and the agreement between clinical and postmortem diagnosis. At admission, most of the 45 patients with cryptococcal meningitis who died, presented more altered consciousness (P = 0.0047), intracranial increased pressure (P = 0.047), and severe malnutrition (P = 0.0006) than the survivors. Of 29 (64.4%) patients with cryptococcal meningitis, 23 died before week 2 on antifungal therapy, and the other six during the next 3 months. The remaining 16 (35.6%) cases had other diagnoses and died soon after. At necropsy, 31 (68.9%) presented disseminated infection involving two or more organs, whereas 14 (31.1%) cases had meningeal or pulmonary localized infection. The agreement of 64.4% between clinical and postmortem diagnosis was similar to some studies. However, other reports have shown figures ranging from 34% to 95%. Currently, a progressive worldwide decrease of autopsies is worrying because the role of postmortem examination is pivotal to verify or identify the death causes, which contributes to improve the quality of clinical diagnosis and medical training.

Benign and malignant neoplasias in 261 necropsies for HIV-positive patients in the period of 1989 to 2008.

Considering that there are some studies with autopsies from AIDS describing only malignant neoplasias and that changes can occur after the introduction of Highly Active Antiretroviral Therapy (HAART), our objectives were to analyze the frequency of benign and malignant neoplasms in AIDS patients in the periods of both pre- and post-HAART. This is a retrospective study with 261 autopsies of HIV-positive patients between 1989 and 2008 in Uberaba, Brazil. Sixty-six neoplasms were found (39 benign, 21 malignant and six premalignant) in 58 patients. The most frequent malignant neoplasms were lymphoid, in 2.7% (four Non-Hodgkin lymphoma, one Hodgkin, one multiple myeloma and one plasmablastic plasmacytoma), and Kaposi's Sarcoma, in 2.3% (six cases). The most frequent benign neoplasms were hepatic hemangiomas in 11 (4.2%) of 261 cases and uterine leiomyoma in 11 (15.7%) of 70 woman. In the pre-HAART period eight (9.8%) benign neoplasias and four (4.9%) malignant occurred in 82 patients; in the post-HAART period, 29 (16.2%) benign and 17 (9.5%) malignant were present; however, the differences were not significant. We conclude that the introduction of HAART in our region doesn't look to have modified the frequency of neoplasms occurring in patients with HIV.

Tendo em vista que trabalhos sobre necropsias de AIDS analisam apenas neoplasias malignas e que ocorreram alterações após a terapia antiretroviral altamente eficaz (HAART), este estudo foi feito com objetivo de avaliar a frequência de neoplasias benignas e malignas nos períodos pré e pós-HAART. Estudo retrospectivo de 261 necropsias de HIV positivos entre 1989 e 2008 em Uberaba - Brasil. Foram encontradas 66 neoplasias (39 benignas, 21 malignas e seis lesões pré-invasivas) em 58 pacientes. As neoplasias malignas mais frequentes foram linfóides, em 2,7 por cento (quatro linfomas não Hodgkin, um Hodgkin, um mieloma múltiplo e um plasmocitoma plasmoblástico) e, sarcoma de Kaposi, em 2,3 por cento (seis casos). As benignas mais frequentes foram hemangiomas hepáticos em 11 (4,2 por cento) dos 261 casos e leiomiomas uterinos em 11 (15,7 por cento) das 70 mulheres. No período pré-HAART ocorreram oito (9,8 por cento) neoplasias benignas e quatro (4,9 por cento) malignas em 82 pacientes; no pós-HAART, 29 (16,2 por cento) benignas e 17 (9,5 por cento) malignas; entretanto, essas diferenças não foram estatisticamente significantes. Concluímos que a introdução da HAART em nossa região não parece ainda ter alterado a frequência de neoplasias em pacientes HIV.

Disseminated toxoplasmosis presenting as sepsis in two AIDS patients.

This report describes two patients who presented acute disseminated and severe toxoplasmosis as the first opportunistic disease related to acquired immunodeficiency syndrome. At admission, clinical and laboratory findings were similar to sepsis or septic shock and a fast evolutive course to death occurred in both cases. At necropsy, an inflammatory reaction and presence of a great number of Toxoplasma gondii cysts and tachyzoites were observed in most organs examined.

O presente relato descreve dois pacientes que apresentaram toxoplasmose aguda, disseminada e grave como primeira manifestação oportunista da síndrome da imunodeficiência adquirida. Os achados clínicos e laboratoriais foram similares aos de sepse ou choque séptico e, em ambos os casos houve evolução rápida para óbito. A necropsia, foi observada reação inflamatória e presença de taquizoítos e cistos de Toxoplasma gondii na maioria dos órgãos examinados.
