Haptoglobin and its association with naturally occurring diseases in Holstein heifer calves / [Haptoglobina e sua associação com doenças ocorridas naturalmente em bezerras da raça Holandesa]

The present study evaluated the use of haptoglobin (Hp) as an indicator of health and performance in 166 Holstein heifer calves reared in an intensive production system. Calves were evaluated at D6-9; D10-13; D20-23; D35-38 and D65-68, corresponding to the days of life. The absence or presence of diseases was evaluated by physical examination and classification of scores. The performance parameters evaluated were body weight, height at withers and hind width. Hp was measured by spectrophotometric technique. The highest prevalence of diarrhea (59.4%; 98/165) was observed in D10-13, bovine respiratory disease (BRD) was on D35-38 (25.8%; 42/163), and umbilical inflammations in D6-D9 (7.8%; 13/166). Highest values of Hp were observed in animals with diarrhea (P=0.02), and umbilical inflammation (P=0.057), in comparison with the group of healthy calves. A significant negative correlation was observed between Hp and performance index. This protein presented an important relation with diarrhea and performance of the calves, opening perspectives on its utilization as a biomarker of diseases.(AU)

O presente estudo avaliou o uso da haptoglobina (Hp) como indicadora de sanidade e desempenho em 166 bezerras Holandesas criadas em um sistema de produção intensivo. As bezerras foram avaliadas nos momentos D6-9; D10-13; D20-23; D35-38 e D65-68, sendo estes correspondentes aos dias de vida. A ausência ou a presença de doenças foi avaliada por meio do exame físico e da classificação por escores. Os parâmetros de desempenho avaliados foram peso corporal, altura de cernelha e largura de garupa. A Hp foi mensurada por técnica espectrofotométrica. A maior prevalência de diarreia (59,4%; 98/165) foi observada em D10-13, doença respiratória bovina (DRB) ocorreu em D35-38 (25,8%; 42/163) e inflamações umbilicais em D6-D9 (7,8%; 13/166). O valor de Hp foi maior nos animais que apresentaram diarreia (P=0,02) e inflamações umbilicais (P=0,057), em comparação ao grupo de bezerras saudáveis. Houve correlação negativa significativa entre a Hp e os índices de desempenho. Essa proteína apresentou uma importante relação com a diarreia e com o desempenho das bezerras, abrindo perspectivas sobre a sua utilização como biomarcadora de doenças.(AU)

Acute phase proteins in bitches subjected to conventional and minimally invasive ovariohysterectomy / Proteínas de fase aguda em cadelas submetidas à ovariohisterectomia convencional e minimamente invasiva

The aim of this study was to evaluate and to compare the possible inflammatory changes by screening acute phase proteins concentrations in healthy bitches subjected to ovariohysterectomy. Minimally invasive and conventional (laparotomy) ovariohysterectomies were performed in 17 client-owned adult female mixed breed dogs. Nine animals were subjected to minimally invasive and eight animals to conventional ovariohysterectomy. Blood samples were taken before surgery, 24, 48 hours, and seven days postoperatively. Serum C-reactive concentration was determined by a commercial ELISA kit and serum haptoglobin concentration was measured via hemoglobin binding assay, both previously validated for use in dogs. As the data did not meet the normal distribution criteria, the nonparametric Kruskall-Wallis was performed to compare quantitative variables between groups. One-way ANOVA and the Friedman test were used for multiple comparisons between time points, with a P<0.05 considered significant. C-reactive protein concentration was significantly different (P<0.0001) at 24 hours postoperatively between groups. There was no significant difference in haptoglobin concentration between groups. C-reactive protein and haptoglobin concentrations were significantly different at 24 and 48 hours postoperatively for minimally invasive and conventional ovariohisterectomies. These findings provided an overview of the short-term inflammatory effects produced by minimally invasive and conventional ovariohysterectomies.(AU)

O objetivo deste trabalho foi avaliar e comparar o efeito inflamatório, por meio da determinação de proteínas de fase aguda, produzido por dois protocolos cirúrgicos distintos de ovariohisterectomia em cadelas. Para tanto, foram determinadas as concentrações de proteína C reativa (CRP) e haptoglobina (Hp) de 17 cadelas, sem raça definida, adultas, sendo nove animais submetidos à ovariohisterectomia pela técnica convencional por laparotomia e oito a ovariohisterectomia pela técnica minimamente invasiva. Para avaliar a resposta de fase aguda causada pelo trauma cirúrgico, amostras de sangue foram obtidas antes dos procedimentos cirúrgicos e em quatro momentos distintos após as cirurgias (24, 48 horas e sete dias) para as dosagens de CRP e Hp, com kit comercial ELISA e via ensaio de ligação com a hemoglobina, respectivamente, validados para o uso em cães. Como não houve distribuição normal dos dados, utilizou-se o teste de Kruskall-Wallis para comparação das variáveis quantitativas entre os dois grupos. Os testes de Friedman e One-way ANOVA foram usados para comparações múltiplas entre os momentos avaliados, sendo considerado P<0,05 como significante. Houve diferença significativa (P<0,0001) para as concentrações de CRP 24 horas após o procedimento cirúrgico entre os dois protocolos utilizados. Não houve diferença significativa para as concentrações de Hp entre os dois protocolos cirúrgicos. Foram evidenciadas alterações significativas para as concentrações de CRP e Hp 24 e 48 horas após as ovariohisterectomias, independentemente da técnica cirúrgica utilizada. As concentrações de CRP e Hp demonstraram o efeito inflamatório imediato induzido pela ovariohisterectomia convencional e minimamente invasiva.(AU)

Serum concentrations of acute phase proteins in goats and ewes with naturally acquired Staphylococcus aureus mastitis / Concentração de proteínas de fase aguda em cabras e ovelhas com mastite de ocorrência natural causada por Staphylococcus aureus

Serum protein concentrations, including acute phase proteins (APPs), of goats and ewes with naturally acquired Sthaphylococcus aureus mastitis were determined by means of SDS-PAGE electrophoresis to evaluate the relevance of these APPs as biomarkers of the disease in these species. Fifteen healthy goats and 5 goats with naturally acquired staphylococci mastitis, as well as fifteen healthy ewes and 5 ewes with staphylococci mastitis were submitted to daily blood sampling during 7 days. In goats, an increase of 570%, 125%, 621%, and 279% in serum concentrations of ceruloplasmin, fibrinogen, haptoglobin and α1-acid glycoprotein, respectively, was observed. In sheep the increase in serum concentrations of ceruloplasmin, fibrinogen, haptoglobin and α1-acid glycoprotein was of 337%, 90%, 461%, and 225%, respectively. Our results indicate that these APPs have considerable potencial as early and sensible biomarkers of mastitis caused by S. aureus in goats and sheep.(AU)

O proteinograma, incluindo proteínas de fase aguda (PFAs), de cabras e ovelhas com mastite de origem natural causada por Staphylococcus aureus, foi determinado por meio de eletroforese em gel de poliacrilamida contendo dodecil sulfato de sódio (SDS-PAGE) a fim de avaliar a importância destas PFAs como biomarcadores da enfermidade nestas espécies. Amostras de sangue foram colhidas diariamente de cinco cabras e cinco ovelhas com mastite estafilocócica naturalmente adquirida, bem como de quinze cabras e quinzes ovelhas saudáveis durante 6 dias consecutivos. Nas fêmeas caprinas, foi verificado aumento dos teores séricos de ceruloplasmina (570%), fibrinogênio (125%), haptoglobina (621%), e α1-glicoproteína ácida (279%). Nas fêmeas ovinas as concentrações de ceruloplasmina, fibrinogênio, haptoglobina e α1-glicoproteína ácida elevaram-se em 337%, 90,9%, 461% e 225%, respectivamente. Os resultados permitem inferir que estas PFAs são marcadores sensíveis e precoces de mastite causada por S. aureus em cabras e ovelhas.(AU)

The stress of weaning influences serum levels of acute-phase proteins, iron-binding proteins, inflammatory cytokines, cortisol, and leukocyte subsets in Holstein calves

The purpose of our study was to investigate changes in immunological parameters induced by weaning stress (including milk restriction) in calves. Fifteen Holstein calves were subjected to weaning at 6 weeks of age. Blood samples were collected at -14, -7, -2, 1, 3, and 5 days post-weaning (DPW; 0 DPW = 42 days). Weaning caused significant (p < 0.01) increases in the neutrophil (NE):lymphocyte (LY) ratio at 5 DPW with a significant (p < 0.05) reduction of LYs. The concentration of acute-phase proteins (haptoglobin and serum amyloid A) also increased significantly (p < 0.05) at 3 and 5 DPW compared to -2 DPW. Levels of the iron-binding protein lactoferrin decreased significantly (p < 0.05) after weaning. Serum tumor necrosis factor-alpha and cortisol levels were elevated (p < 0.05) at 3 DPW, while those of serum interferon-gamma decreased (p < 0.05) at 1 and 3 DPW compared to levels observed before weaning. Weaning significantly (p < 0.05) decreased the percentage of CD25+ T cells in the peripheral blood. In conclusion, weaning stress affected the NE:LY ratio along with the levels of acute phase proteins, lactoferrin, cortisol, and inflammatory cytokines in the peripheral blood of calves. Weaning stress may induce an acute phase response possibly through the elevation of cortisol production and modulation of inflammatory cytokines.

Usefulness of Non-invasive Markers for Predicting Significant Fibrosis in Patients with Chronic Liver Disease

The purpose of this prospective study was to verify and compare the strengths of various blood markers and fibrosis models in predicting significant liver fibrosis. One hundred fifty-eight patients with chronic liver disease who underwent liver biopsy were enrolled. The mean age was 41 yr and male patients accounted for 70.2%. The common causes of liver disease were hepatitis B (67.7%) and C (16.5%) and fatty liver (9.5%). Stages of liver fibrosis (F0-4) were assessed according to the Batts and Ludwig scoring system. Significant fibrosis was defined as > or =F2. Sixteen blood markers were measured along with liver biopsy, and estimates of hepatic fibrosis were calculated using various predictive models. Predictive accuracy was evaluated with a receiver-operating characteristics (ROC) curve. Liver biopsy revealed significant fibrosis in 106 cases (67.1%). On multivariate analysis, alpha2-macroglobulin, hyaluronic acid, and haptoglobin were found to be independently related to significant hepatic fibrosis. A new predictive model was constructed based on these variables, and its area under the ROC curve was 0.91 (95% confidence interval, 0.85-0.96). In conclusion, alpha2-macroglobulin, hyaluronic acid, and haptoglobin levels are independent predictors for significant hepatic fibrosis in chronic liver disease.

Proteomic Analysis of Haptoglobin and Amyloid A Protein Levels in Patients with Vivax Malaria

Advancements in the field of proteomics have provided great opportunities for the development of diagnostic and therapeutic tools against human diseases. In this study, we analyzed haptoglobin and amyloid A protein levels of vivax malaria patients with combinations of depletion of the abundant plasma proteins, 2-dimensional gel electrophoresis (2-DE), image analysis, and mass spectrometry in the plasma between normal healthy donors and vivax malaria patients. The results showed that the expression level of haptoglobin had become significantly lower or undetectable in the plasma of vivax malaria patients due to proteolytic cleavage when compared to healthy donors on 2-DE gels. Meanwhile, serum amyloid A protein was significantly increased in vivax malaria patient's plasma with high statistical values. These 2 proteins are common acute phase reactants and further large scale evaluation with a larger number of patient's will be necessary to establish the possible clinical meaning of the existential changes of these proteins in vivax malaria patients. However, our proteomic analysis suggests the feasible values of some plasma proteins, such as haptoglobin and serum amyloid A, as associating factor candidates for vivax malaria.

Haptoglobin study in myasthenia gravis / Estudo sobre a haptoglobina na miastenia grave

OBJECTIVE: A cross-sectional study of haptoglobin (Hp) in myasthenia gravis (MG) was designed, with the objective to identify its values and correlate them with different disease status. METHOD: 46 patients were enrolled in the study, all having disease severity established according to the quantitative myasthenia gravis strength scores (QMGSS). Based on the functional scale determined by Myasthenia Gravis Foundation of America (MGFA) recommendations, patients were classified as having: complete stable remission (CSR; n=10); minimal manifestations-0 (MM0; n=6), minimal manifestations-1 (MM1; n=4); pharmacological remission (PR; n=6). Two other groups participated: thymomatous patients (T; n=10) and patients without imunosuppression or thymectomy, until the assessment for Hp (WIT; n=10). Hp dosage was done by immunonephelometry, blindly to clinical data. Student's t-test, Anova test and linear regression were employed for statistical analyses. RESULTS: Statistically significant differences occurred between CSR+MM0xWIT groups (86.62x157.57, p<0.001) and PR+MM1xWIT groups (73.93x157.57, p<0.001). Linear regression showed correlation between Hp levels and QMGSS (r=0.759, p<0.001). CONCLUSION: Our results suggest that Hp may be useful in clinical practice as a disease severity marker in MG.

OBJECTIVO: Desenhou-se estudo transversal sobre a haptoglobina (Hp) na miastenia grave (MG) com o objetivo de identificar seus valores e correlacioná-los a diferentes condições na doença. MÉTODO: 46 pacientes foram incluídos, todos tendo a gravidade da doença estabelecida segundo escores internacionais (QMGSS). Os pacientes tiveram seu estado funcional determinado de acordo com a Myasthenia Gravis Foundation of América (MGFA) e classificados em: remissão completa estável (CSR; n=10); mínima manifestação-0 (MM0; n=6), mínima manifestação-1 (MM1; n=4); remissão farmacológica (PR; n=6). Dois outros grupos participaram: pacientes timomatosos (T; n=10) e pacientes sem imunossupressão ou timectomia, até o momento da inclusão no estudo (WIT; n=10). A dosagem de Hp foi realizada por imunonefelometria, de modo cego quanto à clínica. As análises estatísticas incluíram o teste de Student, Anova e regressão linear. RESULTADOS: Observou-se diferença significativa entre os grupos CSR+MM0xWIT (86,62x157,57, p<0,001) e entre PR+MM1xWIT (73,93x157,57, p<0,001). A regressão linear mostrou correlação positiva entre os valores de Hp e os escores QMGSS (r=0,759, p<0,001). CONCLUSÃO: O estudo sugere que valores altos de Hp se correlacionaram a maior gravidade da MG.

Folic acid supplementation does not prevent ribavirin-induced anemia

Treatment of chronic hepatitis C consists of inteferon plus ribavirin. The major adverse effect of ribavirin is hemolytic anemia, a complication that limits therapy. Folic acid supplementation is used to improve erythropoiesis in chronic hemolytic anemia. The aim of this study was to evaluate the effectiveness of folic acid supplementation in the prevention of ribavirin-induced anemia in patients being treated for hepatitis C. Twenty one patients enrolled in treatment protocols for hepatitis C received folic acid 1 mg daily and 22 did not. Groups were similar in age, gender, ribavirin dose and baseline hemoglobin. Folic acid supplementation had no effect in the decrease in hemoglobin or the measured parameters of hemolysis. No difference between males and females was noted for hemoglobin decrease or lowest hemoglobin levels. In our study, folic acid showed no beneficial effect in the prevention of ribavirin-induced anemia.

Hypohaptoglobinaemia as a biochemical and epidemiological marker of falciparum malaria.

OBJECTIVES: The study was conducted in two parts to find out the usefulness of hypohaptoglobinemia (Hpo) as a biochemical and epidemiological marker of malaria. Part-I study was conducted in a Medical College Hospital to find out Hpo in malaria and the time required for normalization of Hpo. Part-II study was undertaken in two endemic areas of malaria to find out the prevalence of Hpo and haptoglobin index (HI) throughout the year along with other indicators of malaria. METHODS: In Part-I study, 172 patients of malaria constituting 58, 52 and 62 patients of cerebral malaria, uncomplicated falciparum malaria and vivax malaria, respectively were enrolled. Along with routine haematological and biochemical investigations, haptoglobin (Hp) estimation was done by endoplate haptoglobin test kit on admission and at 15 days interval for 3 months. In Part-II study Hp was estimated is 305 subjects in two endemic areas of malaria. HI, parasitic index, slide positivity rate (SPR), slide falciparum rate (SFR) were estimated throughout the year and HI was compared with these epidemiological markers. RESULTS: Hpo was present in 102 (92.7%) cases of falciparum malaria which was significantly more than vivax malaria and non-malarial fever. The normalisation of Hpo took about a month or more. The incidence of Hpo was 32.1% is endemic and 4.7% in nonendemic area of malaria. The HI varied between 12.4 to 25.2% throughout the year and was found to be a better marker than other classical markers of malaria. CONCLUSION: Hypohaptoglobinemia may be considered as a useful indirect indicator of falciparum malaria. HI can be used as an epidemiological maker which is better than classical markers of malaria used at present.

Intelligence and genetic markers in Chilean children

Genetic markers and total intelligence quotient (IQ) assessed by WISC (Wechsler Intelligence Scale for Children) were studied in children of both sexes from Santiago, Chile. Heterozygous boys for phosphoglucomutase 1 (PGM) and heterozygous girls for haptoglobin (Hp) had lower IQ than homozygoytes. For ABO system, B girls had lower and B boys had higher IQ than children with other ABO phenotypes. These differences were highly significant with the two tailed t'-test (Student's t-test with the Welch-Satterthwaite correction for degrees of freedom), and most of them remained significant after the correction for multiple comparisons. Girls had greater variance of IQ than boys. Relationships between homozygotes and heterozygotes were found in two independent studies. Thus, the genetic relationship found here seems likely to be a true biotic effect.

Cuatro proteinas en la plasma, ceruloplasmina haptoglobinas y transferinas), fueron analizadas en un grupo control de cuatro provincias de Costa Rica. No se encontro ningun dato significativo; sin embargo, en la provincia de Cartago fueron encontrados una asociacion positiva en relacion a haptoglobinas (X2-5,01 > p >0,05)

Changes of haptoglobin and free hemoglobin due to blood transfusion

Serum total haptoglobin and free hemoglobin levels during blood transfusion were investigated in 17 elective surgeries. Total haptoglobin and free hemoglobin levels in 73 stored whole blood were also investigated for different storage periods. Free hemoglobin was detected in serum when total haptoglobin level became 130 mg/dl or less and a mean storage period of transfused bloods were 11 days or longer. Total haptoglobin level became 130 mg/dl or less at a transfusion volume of 600 ml or more. No constant relationship was recognized between transfusion speed and total haptoglobin or free hemoglobin levels. In the stored whole blood, free hemoglobin level increased in accordance with an increase of storage period and it reached significant increase on 7-9 storage period against 1-3 storage period. The detection rate of free hemoglobin increased significantly when it was stored for 7 days or longer. It was concluded that 7 days or more stored whole bloods had free hemoglobin, but serum free hemoglobin was detected when 600ml or more of 11 days or longer whole bloods were transfused

Determinación de receptores de haptoglobina y proteína C reactiva en linfocitos de pacientes con patología autoinmune e infecciosa / Determination of haptoglobin and C reactive protein receptors in lymphocytes of patients with autoimmune and infectious diseases

En la actualidad, se desconoce el rol del aumento de proteína C recativa (PCR) y haptoglobina (Hp) en la respuesta de fase aguda. Algunos autores han postulado la posibilidad que estas proteínas intervengan en la regulación del sistema inmune. Nuestro estudio estuvo orientado a demostrar la presencia de receptores para Hp y PCR en linfocitos procedentes de niños sanos y niños con patología infecciosa y autoinmune. Para este efecto, se obtuvieron células mononucleares de 48 niños (24 sanos, 14 con infecciones demostradas y 10 con enfermedades autoinmune), se incubaron por 72 horas a 37 grados Celsius y 5 por ciento de CO2, con estímulo de fitohemaglutinina (PHA) y con diferentes concentraciones de PCR y Hp en el medio. Se separaron las subpoblaciones CD4 y CD8 mediante anticuerpos monoclonales unidos a partículas magnéticas y se analizó la presencia de receptores a distintos tiempos (0, 24, 48 y 72 horas) mediante una técnica de inmunofluorescencia indirecta

Sobre esta muestra poblacional (n=50) se determinó la concentración sérica de albúmina, a2 macroglobulina, ceruloplasmina, haptoglobina, transferrina, apolipoproteínas AI y B, Fracciones C3 y C4 de complemento e inmunoglobulina A. Los resultados se compararon con los hallados en la bibliografía nacional e internacional

Hemoglobinopatias e hepatoglobinas em portadores de doença de Chagas / Hemoglobinopathies and haptoglobin in patients with Chagas disease

A endemia chagásica é uma das doenças tropicais mais difundidas e graves, tornando-se um problema de saúde pública de primeira ordem nas Américas do Sul e Central. As condiçöes básicas para a transmissåo da doença indicam que esta endemia é de característica de áreas rurais de baixo nível sócio-econômico. A evoluçåo da doença manifesta-se diferentemente entre os indivíduos e, também, regionalmente. Diferenças de ordem individual e regional såo igualmente observadas em alguns tipos de hemoglobinas anormais e haptoglobinas. Com o objetivo de verificar a prevalência de hemoglobinas anormais e a freqüência de fenótipos de haptoglobinas em chagásicos, analisamos 2.739 amostras de sangue, dos quais 337 pertenciam a pacientes com diagnóstico clínico e laboratorial da doença de Chagas, 1402 tinham sorologia negativa para doença de Chagas (Grupo A) e 1.000 estudantes de 2§ gru de Såo José do Rio Preto (Grupo B). Na análise geral de hemoglobinas anormais, observou-se que a hemoglobina A2 (HbA2) aumentada foi mais prevalente entre chagásicos (8,3 por cento) em comparaçåo com os grupos A (1,21 por cento) e B (0,70 por cento). Análises posteriores comprovaram que este fato nåo se devia à associaçåo da doença de Chagas com talassemia beta heterozigota, principal causa de aumento desta fraçåo hemoglobínica, fato que pode ser indicativo de condiçöes adquiridas. A presença de agregados intraeritrocitários de hemoglobina H (HbH), que é comum na talassemia alfa, também foi mais prevalente entre os portadores da doença de Chagas, notadamente na forma indeterminada da doença (FIDC). Os estudos evidenciaram que esta prevalência também se deve à forma adquirida. A presença de outras hemoglobinas anormais nåo motrou diferenças signficativas entre os portadores da doença de Chagas e os grupos controle. Com relaçåo à estimativa dos valores quantitativos de hemoglobina Fetal (HbF), a média foi menor em portadores de Chagas quando comparados com os grupos sem esta doença, enquanto que para HbA2, sua concentraçåo média foi maior em chagásicos que em nåo chagásicos. Na análise de haptoglobinas obteve-se a qualificaçåo dos três fenótipos mais freqüentes (Hp 1-1, Hp 2-1, Hp 2-2). Os resultados mostraram que tanto em chagásico quanto nos grupos controle o fenótipo Hp 2-1 foi o mais prevalente, seguido de Hp 2-2 e Hp 1-1

Hypothyroidism and anhaptoglobinemia

A case of insulin-dependent diabetes with hypothyroidism was found to be associated with anhaptoglobinemia. The haptoglobin retuned to normal level after treatment with thyroxine suggesting its possible role in haptoglobin synthesis

Haptoglobinas em populaçäo normal e em portadores de cardiopatias valvares / Heptoglobins in normal population and in patients with heart valve diseases

Haptoglobina sérica em 100 doadores de sangue foi determinada utilizando-se da capacidade de ligaçäo da haptoglobina à hemoglobina; os valores médios encontrados foram de 211 ñ 82mg/dl; 38 pacientes portadores de valvopatia valvar foram também estudados e apresentaram valores significativamente mais altos (estenose: 310 ñ 128 e insuficiência 409 ñ 137mg/dl) que a populaçäo normal. A atividade da desidrogenase lática também estava aumentada em pacientes com cardiopatia valvar, indicando a presença de doença sistêmica ou eventual hemólise. Estes dados sugerem ter sido a desidrogenase lática mais sensível que a determinaçäo das haptoglobinas em detectar hemólise intravascular leve, nos doentes estudados

Serum haptoglobin concentrations in acute hepatitis A.

The serum haptoglobin (Hp) values of patients of acute hepatitis, whose serum total-HA antibody in the early clinical stage of the disease were positive, had been investigated. In the early clinical stage of these patients of acute hepatitis A mean serum Hp values were 100.57 +/- 25.20 mg/dl. These values were significantly lower than standard. Hp values of patients gradually increased to the standard values during improvement of the disease. Mean values of Hp in the healing stage of these patients were 128.36 +/- 29.83 mg/dl, and there was no significant difference between values in this stage of the disease and standard. But a significant difference was seen between serum Hp values in those two stages of acute hepatitis A. In this study it was observed that the ability of the Hp biosynthesis in hepatic cells had decreased in the early clinical stage of acute hepatitis A, and it recovered in the healing stage. Serum Hp values could be an indicator in the stage of acute hepatitis A.

Haptoglobina sérica pós-transfusional em pacientes hematológicos / Post-transfusional serum haptoglobin in hematologic patients

A dosagem de haptoglobina foi realizada em 47 pacientes hematológicos antes e 24 horas após transfusäo de sangue. Foram observados aumentos e diminuiçöes pós transfusionais, mas näo houve diferença estatística entre o total de aumentos e o total de decréscimos
