RESUMO
BACKGROUND: Timely access to safe blood and blood components is still a challenge in Nigeria. This study aimed to determine blood donation practices, processing and utilization of blood components across government tertiary hospitals (THs) in Nigeria. METHODS: This was a descriptive cross-sectional study done in Nigeria in June-July 2020. Data were analysed with SPSS version 21.0. RESULTS: Data were collected from 50 THs. The majority (68%) of the THs lack facilities for blood component preparation and only 18% and 32% provide cryoprecipitate and platelet concentrate, respectively. Whole blood was most commonly requested (57.04%). All facilities tested blood for HIV, HBV and HCV, but the majority (23 [46%]) employed rapid screening tests alone and nucleic acid testing was not available in any hospitals. The manual method was the most common method of compatibility testing in 90% (45/50) and none of the THs routinely perform extended red cell typing. The average time to process routine, emergency and uncross-matched requests were a mean of 109.58±79.76 min (range 45.00-360.00), 41.62±25.23 (10.00-240.00) and 11.09±4.92 (2.00-20.00), respectively. CONCLUSION: Facilities for blood component preparation were not widely available. Concerned government authorities should provide facilities for blood component preparation.
RESUMO
Clinical depression is a highly debilitating illness, which is often under-diagnosed and negatively impacts on the quality of life of its sufferers. When it co-exists with other medical conditions, its effect is even more incapacitating. Undiagnosed depression in the context of HIV infection leads to accelerated decline in CD4+ cell counts with concomitant increase in the viral load and poor adherence to the antiretroviral medications which lead to viral mutation and the evolution of resistant strains. This study examined the prevalence of depression, its correlates and the frequency of the diagnosis of the condition among HIV+ subjects on highly active antiretroviral therapy (HAART) by the internists and general physicians at the University of Maiduguri Teaching Hospital in Northeastern Nigeria. Three hundred and fifty representative samples of HIV+ adults on HAART were drawn from the Antiretroviral Therapy Clinic of the Institution. Diagnosis of depression was made using the International Classification of Diseases-10 criteria based on Composite International Diagnostic Interview generated data. Socio-demographic and clinical variables were also analyzed for their correlation with depression in the subjects. About 20% of the respondents were diagnosed with clinical depression and no diagnosis of the condition was hitherto entertained in all the respondents. The independent determinants of depression in the participants were: female gender [odds ratio (OR)=3.87 (95% confidence interval, CI: 2.089-7.183)], past history of psychiatric illness [OR=43.81 (95% CI: 9.731-197.30)] and family history of psychiatric illness in first-degree relatives of the subjects [OR=14.364 (95% CI=5.327-38.729)]. Depression is a relatively common psychiatric condition among adults on HAART, there is therefore the need for routine screening of this condition among HIV+ subjects in order to optimize patient care and improve clinical outcomes.
RESUMO
In a previous retrospective study, it was observed that the greater the amounts of the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in the blood, the lesser the number of complications of sickle cell disease (SCD) and the higher the steady state haemoglobin level. SCD causes ischaemia-reperfusion injury and inflammation; which can be ameliorated by a metabolite of DHA that down-regulates expression of pro-inflammatory genes. The objectives of this prospective pilot study were to evaluate the effects of DHA and EPA supplements in SCD, and test the hypothesis that these effects are mediated partly by reducing inflammation. Oral DHA and EPA supplements were given to 16 SCD patients for 6 months. We then compared pre- and post-supplementation values of number of crisis, steady state Hb, plasma unconjugated bilirubin and three indices of inflammation: plasma interleukin-6, blood neutrophil and platelet counts. There was a significant reduction in the plasma level of unconjugated bilirubin, and the number of sickle cell crisis; but not in the markers of inflammation. The pilot data suggest that DHA and EPA supplements reduce the number of crisis and steady state haemolysis in SCD; but provide no evidence that these effects are mediated by reducing inflammation.
