BACKGROUND Anemia, neutropenia, and thrombocytopenia are commonly observed in HIV-infected patients. This study was undertaken to evaluate the prevalence of cytopenias and their association with CD4 count. Furthermore, the association of hemoglobin concentration with mortality was also investigated. METHODS We reviewed the data of 701 HIV-infected(More)
Microparticles (MPs) are present in healthy subjects and their concentration increases in patients at high risk of thrombosis. We evaluated 10 patients with sickle cell anemia (SCA) treated with hydroxyurea (HU) and 13 SCA patients without this treatment. MP concentrations were determined by flow cytometry. Coagulation was evaluated using the(More)
OBJECTIVE The objective of this study was to verify the evolution of pregnancies in sickle cell patients followed at one institution over a period of 12 years (January 2000 to June 2012). METHODS The study evaluated 34 pregnant women with sickle cell disease with a mean age of 23.9±5.3 years. The incidence of obstetric complications, non-obstetric(More)
CONTEXT Rhabdomyolysis is a severe and life-threatening condition in which skeletal muscle is damaged. Acute renal failure due to rhabdomyolysis has been widely described and its main pathophysiological mechanisms are renal vasoconstriction, intraluminal cast formation and direct myoglobin toxicity. OBJECTIVE To report on a case of acute renal failure(More)
Hyperamylasemia has been reported in more than 65% of patients with severe leptospirosis, and the true diagnosis of acute pancreatitis is complicated by the fact that renal failure can increase serum amylase levels. Based on these data we retrospectively analyzed the clinical and histopathological features of pancreas involvement in 13 cases of fatal human(More)
CONTEXT AND OBJECTIVES Sickle cell disease (SCD) is the most common genetic disorder among people of African descent, affecting approximately 3,500 newborns each year in Brazil. Hydroxyurea (HU) is the only effective drug to treating patients with SCD, thereby reducing morbidity and mortality. The objective was to analyze the effects of HU on SCD patients(More)
Intrahepatic cholestasis (SCIC) is an uncommon but potentially fatal complication of sickle cell disease (SCD), with a high death rate, observed mainly in patients with homozygous sickle cell anemia. Herein, we describe a case of severe SCIC treated successfully with aggressive manual exchange transfusion (ET). The patient was admitted with enlarged liver(More)
BACKGROUND There is no standard treatment for patients with severe anemia who refuse blood transfusion or cannot receive red blood cells. CASE REPORT After an orthotopic liver transplantation, an elderly Jehovah's Witness who refused blood transfusion presented with severe acute anemia with hemorrhagic shock. The calculated red blood cell loss was near(More)
Germ cell tumor (GCT) is the most frequent cancer in young men and is highly curable. Almost 80 % of patients with the disease in an advanced stage achieve a reliable response to cisplatin combination chemotherapy. For relapsing or refractory disease, autologous hematopoietic stem cell transplantation (HSCT) is an effective therapy. The two most used(More)
OBJECTIVE Sickle cell anemia and the interaction S/Beta thalassemia differ in hematological values due to microcytosis and hypochromia caused by the thalassemic mutation. The clinical benefit of long-term hydroxyurea treatment is undeniable in sickle cell disease with monitoring of the biological action of the drug being by the complete blood count. The(More)
