Multidisciplinary approach to obstetric disseminated intravascular coagulopathy management in low-income country: A survey.

OBJECTIVE: To assess the uptake of a multidisciplinary team approach in obstetric disseminated intravascular coagulopathy (DIC) management in a low- to middle-income country. METHODS: A cross-sectional observational study, in which a semi-structured and pre-tested questionnaire was used to collect data on the uptake by Nigerian obstetricians of the multidisciplinary team approach to obstetric DIC management. RESULTS: A total of 171 obstetricians responded, 82 (48.0%) were consultants and 89 (52.0%) were specialist registrars. Most (165; 96.5%) practiced in tertiary healthcare facilities and the multidisciplinary team approach was the most preferred (162; 94.7%) management approach. In all, 142 (83.0%) supported the invitation of hematologists always in the management whereas 115 (67.3%) participants recommended that involvement of specialists in the treatment should be when clinical presentation was suggestive of DIC. No significant association existed between years of obstetric practice and adoption of a multidisciplinary team-based approach (χ2 = 9.590; P = 0.252). CONCLUSION: A multidisciplinary approach is widely adopted in the management of obstetric DIC, with hematologists being a key member of the team.

Plasma concentration of fucosyltransferase 7 is not associated with the number of clinically overt vaso-occlusive events in sickle cell disease.

Objective: To determine if the number of vaso-occlusive events in SCD relates to plasma concentration of fucosyltransferase 7 (FUT7), which catalyses the synthesis of selectin ligands. Design: A prospective, analytical study. Setting: Haematology and Chemical Pathology Departments of tertiary healthcare centres. Participants: Steady state HbSS individuals aged 13-45 years, 20 had 3 or more vaso-occlusive crises that required hospital admission in the previous year (with or without complications of SCD); 17 other HbSS persons had 0-1 vaso-occlusive crisis that required hospital admission in the previous year and no disease complications. Intervention: Steady-state plasma concentrations of FUT7 measured by ELISA were compared between SCD patients who had one vaso-occlusive crisis requiring hospital treatment in the previous year but no disease complications and those who had >3 crises with or without complications. Main Outcome Measures: Plasma level of FUT7and the number of vaso-occlusive events in each HbSS patient. Results: Mean + standard deviation plasma concentration of FUT7 was 8.6 + 2.7 ng/ml in patients with >3 vasoocclusive crises in the previous year and 7.3 + 1.7 ng/ml in those with 0-1 crisis and no complications; independent sample t-test, p > 0.05, not significantly different. Conclusion: Plasma concentration of fucosyltransferase7 is not associated with the number of vaso-occlusive events in sickle cell disease. Funding: None declared.

Diagnosis and treatment of bbstetrics disseminated intravascular coagulation in resource limited settings.

Background: Disseminated intravascular coagulation (DIC) is one of the commonest causes of abnormal bleeding during pregnancy and puerperium. Its successful management is a challenging feat in resource limited settings (RLS). Aim: To determine Obstetricians' approach in diagnosing and treating obstetrics DIC in a RLS. Method: A semi-structured pre-tested 4-sectioned questionnaire was used to collect demographic data of Nigerian obstetricians and data on their practice in the diagnosis and treatment of obstetrics DIC. Results: A total of 171 obstetricians responded. Preeclampsia was the most frequent cause identified (70.2%) followed by postpartum haemorrahge (58.3%). Platelet count determination was the test mostly used (95.9%) to make a diagnosis of DIC whereas, antithrombin assay was the least (20.6%) requested investigation. While about two-third would monitor the evolution of DIC, a little less than half of the obstetricians would not repeat laboratory testing more than every 2 days, reason mainly (61.8%) due to patient's financial constraint. Almost three-quarter of them preferred fresh whole blood as the first line of treatment of DIC. Conclusion: DIC remains a challenge in the obstetrics practice in RLS especially in investigations, monitoring and index of suspicion for non-overt DIC.

Presenting features and treatment outcomes of chronic lymphocytic leukaemia in a resource poor Southern Nigeria.

Background: Chronic lymphocytic leukaemia is a relatively common haematological malignancy affecting older adults, accounting for about 20% of haematological malignancies in Nigeria. Diagnosis of this disease depends on the demonstration of clonal lymphocytosis > 5 × 109/L with a characteristic immunophenotypic pattern amidst other clinical and laboratory features. Objectives: To determine the predominant clinical and laboratory features of CLL at presentation and their relationship with patient survival. This study also aims at examining the relationship between treatment protocol and outcome. Methods: This is a retrospective study with 8 years data (2010-2018) collected from four different centers. Data was analyzed using SPSS 20.0. Results: There were a total of 97 cases, with a male: female ratio of 1.1:1. The median age at presentation was 59 years. Approximately 55% of the patients presented at Binet stage C, with splenomegaly in 93.2% and 78% were anaemic. The mean white cell count was 137.9 ± 14.7 × 109/L, with a median absolute lymphocyte count of 86 × 109/L. The commonest treatment regimen was chlorambucil and prednisolone and males had a superior response. The number of chemotherapy cycles, serum alkaline phosphatase and aspartate transaminase correlated positively with duration of survival. Mortality rate over the five year period was 14.3%. Conclusion: CLL was found to present in younger patients when compared to previous studies with a median age of 57 years at diagnosis. Our study showed a slight female preponderance and better response to therapy in males. Majority of the patients presented in Binet stage C and were treated with chlorambucil-based drug combinations compared to more current treatment with Fludarabine-based combinations. A high serum alanine transaminase and alkaline phosphatase was found to positively correlate with survival amongst this patient population.
