Invasive Aspergillosis among Haematological Malignancy Patients in Ghana: A Pilot Study on Prevalence and Antifungal Prophylaxis at the National Referral Hospital.

BACKGROUND: Invasive aspergillosis (IA) among haematological malignancy patients is rarely diagnosed or studied in many African countries. Aspergillus galactomannan (GM) enzyme immunoassay (EIA) utilized in aiding diagnosis is not readily accessible in Ghana. Previous studies have evaluated the IMMY sona Aspergillus GM lateral flow assay (LFA) and suggested it as a potential alternative to the GM EIA. OBJECTIVES: We aimed to use the LFA in international (EORTC/ MSGERC) definitions to obtain preliminary data on IA among patients with haematological malignancies in Ghana with a focus on the prevalence and antifungal prophylaxis. METHODS: We conducted a pilot study among patients with haematological malignancies at the Korle-Bu Teaching Hospital, Ghana using the LFA, culture and computed tomography scan to screen for and classify IA cases according to international definitions. RESULTS: A total of 56 adult patients were recruited including acute leukaemia 14 (25.0%), chronic leukaemia 38 (67.9%), and lymphoma 4 (7.1%). Nine (16.1%) patients had a history of severe neutropenic episodes. All patients were on at least one chemotherapy drug. Three (5.4%) patients met the criteria for IA, comprising two probable IA in acute myeloid leukaemia and one possible IA in non-Hodgkin's lymphoma and constitutes one of five (20%) patients with ongoing severe neutropenia. The LFA was diagnostic in two IA patients. The IA cases were among 49 (87.5%) patients who did not receive antifungal prophylaxis. CONCLUSION: Proactive diagnostic approaches to IA and effective antifungal prophylaxis may be significant in the management of haematological malignancy patients with severe neutropenia in Ghana.

CONTEXTE: L'aspergillose invasive (AI) parmi les hémopathies malignes est rarement diagnostiquée ou étudiée dans de nombreux pays africains et le dosage immunoenzymatique (EIA) d'Aspergillus galactomannane (GM) utilisé pour faciliter le diagnostic n'est pas facilement accessible. Le test à flux latéral (TFL) IMMY sona® Aspergillus GM récemment introduit est évalué et suggéré comme alternative au GM EIA. OBJECTIFS: Nous avons cherché à utiliser les définitions TFA et les définitions internationales (EORTC/MSGERC) pour obtenir des données préliminaires sur l'AI dans les hémopathies malignes au Ghana en mettant l'accent sur la prévalence et la prophylaxie antifongique. MÉTHODES: Nous avons mené une étude pilote auprès de patients atteints d'hémopathie maligne à l'hôpital universitaire de Korle-Bu, au Ghana, en utilisant le TFL, la culture et la tomodensitométrie pour dépister et classer les cas d'AI selon les définitions internationales. RESULTATS: Au total, 56 patients adultes ont été recrutés, dont une leucémie aiguë (25 %), une leucémie chronique (67,9 %) et un lymphome (7,1 %), neuf (16,1 %) ayant des antécédents d'épisodes neutropéniques. La plupart des patients (70 %) avaient une maladie évolutive. Trois patients répondaient aux critères d'AI, comprenant deux AI probables et une AI possible, uniquement chez des patients atteints de leucémie aiguë et un sur cinq (20 %) avec une neutropénie en cours. Le TFL était utilisé comme méthode de diagnostique chez deux patients d'AI. Les cas d'AI concernaient tous les 49 (87,5 %) des patients n'ayant pas reçu de prophylaxie antifongique. CONCLUSION: L'AI a probablement une incidence de 5,4 % dans les leucémies, mais de 20 % chez les patients neutropéniques et chez aucun patient recevant une prophylaxie antifongique. Des approches diagnostiques proactives de l'AI et une prophylaxie antifongique efficace peuvent être importantes dans la prise en charge des hémopathies malignes au Ghana.

Pregnancy outcomes in women with sickle-cell disease in low and high income countries: a systematic review and meta-analysis.

BACKGROUND: Pregnancy in women with sickle-cell disease (SCD) is associated with increased adverse outcomes. Findings on the association between SCD and adverse pregnancy outcomes are conflicting, and the results do not address whether these associations are similar in both low- and high-income countries. OBJECTIVES: We conducted a systematic review and meta-analysis to evaluate pregnancy outcomes associated with SCD. SEARCH STRATEGY: The MEDLINE database was searched using medical subject headings (MeSH) and keywords for articles on pregnancy outcomes in women with SCD. SELECTION CRITERIA: We used full research articles published in English that compared women with SCD with women who did not have SCD, as controls. DATA COLLECTION AND ANALYSIS: Data were abstracted and analysed using comprehensive Meta-analysis 2.2. The primary outcomes were intrauterine growth restriction and perinatal mortality. Secondary outcomes were rates of caesarean sections, pre-eclampsia, eclampsia, postpartum haemorrhage, maternal mortality, prematurity, and low birthweight. Random-effects models were used to calculate pooled odds ratios (ORs) with 95% confidence intervals (95% CIs). MAIN RESULTS: Sixteen studies met all of the selection criteria and were included in the analysis. SCD was associated with intrauterine growth restriction (pooled OR 2.79, 95% CI 1.85-4.21), perinatal mortality (pooled OR 3.76, 95% CI 2.34-6.06), and low birthweight (pooled OR 2.00, 95% CI 1.42-2.83). SCD was also associated with an increased risk of pre-eclampsia (pooled OR 2.05, 95% CI 1.47-2.85), maternal mortality (pooled OR 10.91, 95% CI 1.83-65.11, P = 0.009), and eclampsia (pooled OR 3.02, 95% CI 1.20-7.58). CONCLUSION: Pregnancy in women with SCD is associated with increased risks of adverse perinatal and maternal outcomes in both low- and high-income countries. TWEETABLE ABSTRACT: This meta-analysis showed worse pregnancy outcomes in women with sickle-cell disease compared with controls.

Second Trimester Anaemia in Pregnant Ghanaians.

BACKGROUND: Anaemia is considered a severe public health problem by WHO and is seen as such in Ghana. Its prevalence in pregnancy has remained high despite improved antenatal care. The main purpose of this study was to determine the current anaemia prevalence and aetiology other than iron deficiency. METHODS: This was a cross-sectional study. A total of 214 pregnant women were studied. Women were administered a questionnaire related with the subject and blood samples were drawn. Full blood count was performed within four hours and serum iron, folate and vitamin B12 were studied. Other tests done included sickling and Hb electrophoresis , stool routine examination for hookworm infestation, thick and thin film for malaria parasitaemia. Dietary intake was also looked at to determine whether it contributed to anaemia seen in these subjects. RESULTS: Anaemia was detected in 150 (70%) of the 214 pregnant women studied. Using the World Health Organisation criteria for anaemia, 81 subjects had mild, 66 moderate and 3 had severe anaemia. Anaemia was more prevalent in young adults (82%) than in teenagers and subjects above 35years (p=0.018). Primigravidae (21%) and multigravidae (67%) were more likely to be anaemic than grandmultigravidae (12%). Anaemia was more prevalent in the low social class group (94%). Nutritional intake of both anaemic and non-anaemic subjects was found to be adequate and thus iron deficiency anaemia, which was found to be the commonest cause of anaemia, was probably due to intake of diet low in bioavailable iron. There was very little consumption of fruits and vegetables that facilitate iron absorption. Twenty seven anaemic subjects had low serum iron levels. Transferrin saturation was low in 39 subjects; 24 of these also had low serum iron, which was suggestive of iron deficiency. Folate and vitamin B12 deficiency did not play significant role in the aetiology of anaemia. Malaria and hookworm infestation were also not found to be significant in the causation of anaemia. CONCLUSIONS: The prevalence of anaemia (70%) in pregnant Ghanaians in their second trimester is unacceptably high. Twenty seven (18%) of the 70% anaemic subjects had low serum iron and six (4%) had low serum folate levels. None of the subjects had vitamin B12 deficiency. Generally dietary intake in pregnant women in this study was adequate, but significant proportion of their meals was of the type low in bioavailable iron as more cereals and tubers were consumed. The kind of diet, which most people can afford in Africa is low in proteins and vitamins, but high in carbohydrate with high phytate contents and this reduces iron absorption. Iron and folic acid prophylaxis for all women of child bearing age is recommended and emphasis on a more balanced nutritional intake at antenatal clinics should be encouraged.

Multicentric Castleman's disease in a Ghanaian adult.

Castleman's disease is a rare cause of lymphoid hyperplasia that may result in localized symptoms or an aggressive, multisystem disorder that can mimic other diseases like lymphoma or tuberculosis. We describe a case of a 55-year-old Ghanaian male who was successfully diagnosed and managed for multicentric Castleman's disease with combination chemotherapy.

Haemophagocytic lymphohistiocytosis in a Ghanaian child.

We report a case of a previously well nine-month-old infant who presented with prolonged fever, hepatosplenomegaly and pancytopenia. A diagnosis of haemophagocytic lymphohistiocytosis (HLH) was made during the course of hospital admission. There was good initial response to dexamethasone but the patient died less than two months after diagnosis. This is the first report of HLH from Ghana. The disease has a significant mortality rate if untreated and a high index of suspicion is required in all severely ill children.
