Associations between malaria in pregnancy and neonatal neurological outcomes.

OBJECTIVE: To compare neurological functioning of neonates born to mothers with and without malaria in pregnancy. METHODS: Pregnant women presenting at Korle Bu Teaching Hospital, Ghana were recruited into this prospective observational study. Malaria exposure was determined by clinically documented antenatal malaria infection; parasitemia in maternal, placental, or umbilical cord blood; or placental histology. Neurological functioning was assessed using the Hammersmith Neonatal Neurological Examination within 48 hours of birth. Performance was classified as "optimal" or "suboptimal" by subdomain and overall. RESULTS: Between November 21, 2018 and February 10, 2019, a total of 211 term-born neonates, of whom 27 (13%) were exposed to malaria in pregnancy, were included. In the reflexes subdomain, exposed neonates tended to score lower (adjusted mean difference -0.34, 95% confidence interval -0.70 to 0.03), with an increased risk (adjusted risk ratio 1.63, 95% confidence interval 1.09 to 2.44) of suboptimal performance compared with unexposed neonates. There were no significant between-group differences in scores or optimality classification for the remaining subdomains and overall. CONCLUSIONS: Malaria-exposed neonates had similar neurological functioning relative to unexposed neonates, with differences confined to the reflexes subdomain, suggesting potential underlying neurological immaturity or injury. Further studies are needed to confirm these findings and determine the significance of malaria in pregnancy on long-term neurological outcomes.

Establishing a Cancer Registry in a Resource-Constrained Region: Process Experience From Ghana.

PURPOSE: In a review of cancer incidence across continents (GLOBOCAN 2012), data sources from Ghana were classified as Frequencies, the lowest classification for inclusion, signifying the worst data quality for inclusion in the analysis. Recognizing this deficiency, the establishment of a population-based cancer registry was proposed as part of a broader cancer control plan. METHODS: The registry was examined under the following headings: policy, data source, and administrative structure; external support and training; and definition of geographic coverage. RESULTS: The registry was set up based on the Ghana policy document on the strategy for cancer control. The paradigm shift ensured subscription to one data collection software (CanReg 5) in the country. The current approach consists of trained registrars based in the registry who conduct active data abstraction at the departments and units of the hospital and pathologic services. To ensure good governance, an administrative structure was created, including an advisory board, a technical committee, and registry staff. External support for the establishment of the Accra Cancer Registry has come mainly from Stanford University and the African Cancer Registry Network, in collaboration with the University of Ghana. Unlike previous attempts, this registry has a well-defined population made up of nine municipal districts. CONCLUSION: The Accra Cancer Registry was established as a result of the lessons learned from failed previous attempts and aim to provide a model for setting up other cancer registries in Ghana. It will eventually be the focal point where all the national data can be collated.

Cytological and Wet Mount Microscopic Observations Made in Urine of Schistosoma haematobium-Infected Children: Hint of the Implication in Bladder Cancer.

BACKGROUND: Schistosomiasis is the second major human parasitic disease next to malaria, in terms of socioeconomic and public health consequences, especially in sub-Saharan Africa. Schistosoma haematobium (S. haematobium) is a trematode and one of the species of Schistosoma that cause urogenital schistosomiasis (urinary schistosomiasis). Although the knowledge of this disease has improved over the years, there are still endemic areas, with most of the reported cases in Africa, including Ghana. Not much has been done in Ghana to investigate cytological abnormalities in individuals within endemic communities, although there are epidemiologic evidences linking S. haematobium infection with carcinoma of the bladder. AIM: The aim of this study was to identify microscopic and cytological abnormalities in the urine deposits of S. haematobium-infected children. METHODOLOGY: Three hundred and sixty-seven (367) urine samples were collected from school children in Zenu and Weija communities. All the samples were examined microscopically for the presence of S. haematobium eggs, after which the infected samples and controls were processed for cytological investigation. RESULTS: S. haematobium ova were present in 66 (18.0%) out of the 367 urine samples. Inflammatory cells (82%, 54/66), hyperkeratosis (47%, 31/66), and squamous cell metaplasia (24%, 16/66) were the main observations made during the cytological examination of the S. haematobium-infected urine samples. CONCLUSION: Cytological abnormalities in S. haematobium-infected children may play an important role in the severity of the disease, leading to the possible development of bladder cancer in later years, if early attention is not given. Therefore, routine cytological screening for urogenital schistosomiasis patients (especially children) at hospitals in S. haematobium-endemic locations is recommended.

Reliable cell and tissue morphology-based diagnosis of endemic Burkitt lymphoma in resource-constrained settings in Ghana.

BACKGROUND: Endemic Burkitt lymphoma (eBL) is an aggressive B-cell lymphoma, which is a common childhood cancer in areas with intense transmission of Plasmodium falciparum parasites. Early and accurate diagnosis is a prerequisite for successful therapy, but it optimally involves advanced laboratory investigations. These are technologically demanding, expensive, and often difficult to implement in settings where eBL is prevalent. Diagnosis is thus generally based on clinical assessment and morphological examination of tumour biopsies or fine-needle aspirates (FNAs). METHODS: The purpose of the present study was to assess the accuracy of eBL diagnosis at two tertiary hospitals in Ghana. To that end, we studied FNAs from 29 eBL patients and 21 non-eBL lymphoma patients originally diagnosed in 2018. In addition, we examined 111 archival formalin-fixed and paraffin-embedded (FFPE) biopsies from Ghanaian patients originally diagnosed as eBL (N = 55) or non-eBL (N = 56) between 2010 and 2017. Availability-based subsets of samples were subjected to haematoxylin-eosin or Giemsa staining, C-MYC immunohistochemistry, and fluorescence in situ hybridisation (FISH) analysis of c-myc rearrangements. RESULTS: We found a good correlation between original diagnosis and subsequent retrospective assessment, particularly for FNA samples. However, evidence of intact c-myc genes and normal C-MYC expression in samples from some patients originally diagnosed as eBL indicates that morphological assessment alone can lead to eBL over-diagnosis in our study area. In addition, several FFPE samples could not be assessed retrospectively, due to poor sample quality. Therefore, the simpler FNA method of obtaining tumour material is preferable, particularly when careful processing of biopsy specimens cannot be guaranteed. CONCLUSION: We conclude that the accuracy of eBL diagnostic tools available in Ghana is generally adequate, but could be improved by implementation of additional pathology laboratory investigations. Improved attention to adequate preservation of archival samples is recommended.

Helicobacter pylori cagA and vacA genes in dyspeptic Ghanaian patients.

BACKGROUND: Helicobacter pylori infection is prevalent in Ghana. The development of gastro-duodenal disease is dependent on virulence of the infecting strain, host susceptibility and environmental factors. Helicobacter pylori cagA and vacA strains induce more inflammation, ulceration and oncogenesis. Here, for the first time we present data on H. pylori cagA and vacA genes and their association with gastro-duodenal disease in Ghana. A total of 159 patients with dyspepsia at Korle-Bu Teaching Hospital, Accra, were investigated for H. pylori with urease-CLO, of which 113 (71.1%) were positive. Genomic DNA was extracted from antral biopsies using QIAGEN DNeasy kit. Detection of H. pylori vacA and cagA genes were determined by PCR as previously described. RESULTS: In total, 110 (69.2%) vacAs1, 71 (44.7%) vacAm1, 35 (22.0%) vacAm2, 77 (48.4%) cagA-(hydrophilic region) and 109 (68.6%) cagA-(internal duplication region) were detected. In multivariate analysis, duodenal ulcer was more likely than other diagnoses to have detectable cagA-(hydrophilic region) (OR 3.1 CI 1.2-7.9) or vacAs1m1 (OR 6.5 CI 1.2-34.0). CONCLUSIONS: Majority of biopsies were colonized with H. pylori harboring both cagA and vacA. H. pylori cagA-(internal duplication region) was more prevalent than cagA-(hydrophilic region). Duodenal ulcer was more likely than other diagnoses to have detectable cagA-(hydrophilic region) or vacAs1m1.

Factors associated with gastro-duodenal disease in patients undergoing upper GI endoscopy at the Korle-Bu Teaching Hospital, Accra, Ghana.

BACKGROUND: There is a high prevalence of gastro-duodenal disease in sub-Saharan Africa. Peptic ulcer disease in dyspeptic patients, 24.5%, was comparable to prevalence of gastro-duodenal disease among symptomatic individuals in developed countries (12 - 25%). Limited data exists regarding its associated risk factors despite accumulating evidence indicating that gastroduodenal disease is common in Ghana. OBJECTIVES: This study investigates risk factors associated with gastro-duodenal disease at the Korle-Bu Teaching Hospital, Accra, Ghana. METHODS: This study utilized a cross-sectional design to consecutively recruit patients referred with upper gastro-intestinal symptoms for endoscopy. The study questionnaire was administered to study participants. Helicobacter pylori infection was confirmed by rapid-urease examination at endoscopy. RESULTS: Of 242 patients sampled; 64 had duodenal ulcer, 66 gastric ulcer, 27gastric cancer and 64 non-ulcer dyspepsia. Nineteen (19) had duodenal and gastric ulcer while 2 had gastric ulcer and cancer. A third (32.6%) of patients had history of NSAID-use. H. pyloriwas associated with gastric ulcer (p=0.033) and duodenal ulcer (p=0.001). There was an increased prevalence of duodenal ulcer in H. pylori-infected patients taking NSAIDs, P=0.003. CONCLUSION: H. pylori was a major risk factor for peptic ulcer disease. However, NSAID-related gastro-duodenal injury has been shown to be common in H. pylori infected patients. It highlights the need for awareness of the adverse gastro-intestinal effects in a H. pylori endemic area.

Ovarian Tumors in Children and Adolescents: A 10-Yr Histopathologic Review in Korle-Bu Teaching Hospital, Ghana.

To determine the histopathologic types, frequency of occurrence, age distribution, presenting signs, and symptoms of ovarian tumors in children and adolescents diagnosed at the Korle-Bu Teaching Hospital all histopathology slides and request cards of ovarian tumors diagnosed in subjects aged, 0 to 19 yr over a 10-yr period (2001-2010) were reviewed. Biographical and clinical data of the patients were collected. The results were entered into Epi-info to determine the frequency of various ovarian tumors in different age groups and their association with presenting signs and symptoms. A total of 67 (9.5%) ovarian tumors were diagnosed in patients aged 0 to 19 yr of a total of 706 diagnosed in all age groups during the period. The majority [44 (65.7%)] were germ cell tumors, the commonest being mature cystic teratoma. Burkitt lymphoma was the single most common malignant tumor, comprising 6(9%) of all the tumors, although as a group malignant germ cell tumors were still the most common malignant ovarian tumors in children and adolescents. Although germ cell tumors were the most common tumors in this age group (both benign and malignant), Burkitt lymphoma, a peculiar malignant tumor in this subregion, was the single most common malignant tumor of the ovary.

Unrecognized human immunodeficiency virus infection and risk factors among elderly medical patients at the Korle Bu teaching hospital, Accra, Ghana.

BACKGROUND: The human immunodeficiency virus (HIV) infection usually infects persons in the reproductive age group (15-49 years), but elderly people are also susceptible. Many people in sub-Saharan Africa including Ghana believe that elderly people are not at risk for HIV. Despite numerous reports of the high prevalence of HIV infection among the elderly worldwide, there are no from Ghana. This work determined the sero-prevalence of HIV infection and risk factors for its transmission among 1,100 hospitalized elderly people at the Korle Bu Teaching Hospital (KBTH), Accra, Ghana. METHODS: Subjects voluntarily completed a risk-factor questionnaire and provided a blood specimen for HIV testing. RESULTS: Of the study participants, 440 were male (mean age: 64 ± 10.55 years), and 660 were female (mean age: 63 ± 9.51 years). The overall HIV-1 sero-prevalence among the subjects was 4.18 % (n = 46). On multivariate analysis, there was no statistical significance between the socio-demographics or risk factors and the HIV status of the participants. CONCLUSION: The results suggest high prevalence of HIV-1 among hospitalized elderly people at KBTH, recommending the need to include the elderly in HIV/AIDS testing, prevention, and control programmes. TRIAL REGISTRATION: Trial registration number: MS-Et/M.9 - p4.10/2012-2013. Registered: 10th April, 2013.

Human immunodeficiency virus, Hepatitis B virus and syphilis infections among longdistance truck drivers in, a Port City in Ghana

Although the high prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV) and syphilis infections among longdistance truck drivers has been well documented globally, such data are sparse from Africa, and there has been no such data from Ghana. This study carried out between the months of January and June 2013 sought to determine the sero-prevalence and risk factors of HIV, HBV and syphilis infections among long distance truck drivers at the Tema sea port, Ghana. Materials and Methods: Of a total of 800 eligible drivers, 106 (13.25%) drivers consented to take part in the study. Subjects voluntarily completed a risk factor questionnaire and provided blood specimen for testing for HIV, syphilis and the surface antigen of HBV (HBsAg). Results: The mean age of the drivers was 40.56 ± 11.56 years. The sero-prevalence of HIV was 0.94%, 14.2% had HBsAg and reactive syphilis serology was 3.8%. On multivariate analysis, the main determinants of HBV infection were; multiple sexual partnership (OR, 6.36; 95% CI: 1.35­29.79), patronage of commercial sex workers (OR, 6.85; 95% CI: 0.88 ­ 52.89), cross-border travelers (OR: 6.89-fold, 95% CI: 0.86 - 55.55) and prolonged duration of trips for more than two weeks (OR: 4.76; 95% CI: 0.59 ­ 38.02). The main determinant of syphilis infection on multivariate analysis was being a Muslim (OR, 2.19; 95% CI: 0.22 ­ 21.74). Conclusion: The data indicate a lower sero-prevalence of HIV but a higher sero-prevalence of syphilis. However, the sero-prevalence of HBV infection is comparable to that of the general population

Triple-Negative Breast Cancer in Ghanaian Women: The Korle Bu Teaching Hospital Experience.

Breast cancers that have negative or extremely low expression of estrogen receptor and progesterone receptor and non-amplification of human epidermal growth factor receptor-2 (HER2)/neu are termed triple-negative breast cancer (TNBC). The majority of TNBC tumors belong to the biologically aggressive basal subtype, and they cannot be managed with targeted endocrine or anti-HER2/neu agents. In western, high resource environments, risk factors for TNBC include younger age at diagnosis and hereditary susceptibility. Women of African ancestry in the United States and in continental Africa have higher frequencies of TNBC, prompting speculation that this risk may have an inherited basis and may at least partially explain breast cancer survival disparities related to racial/ethnic identity. Efforts to document and confirm the breast cancer burden of continental Africa have been hampered by the limited availability of registry and immunohistochemistry resources. Our goal was to evaluate the breast cancers diagnosed in one of the largest health care facilities in western Africa, and to compare the frequencies as well as risk factors for TNBC versus non-TNBC in this large referral tertiary hospital. The Korle Bu Teaching Hospital is affiliated with the University of Ghana and is located in Accra, the capital of Ghana. We conducted an institutional, Department of Pathology-based review of the breast cancer cases seen at this facility for the 2010 calendar year, and for which histopathologic specimens were available. The overall study population of 223 breast cancer cases had a median age of 52.4 years, and most had palpable tumors larger than 5 cm in diameter. More than half were TNBC (130; 58.3%). We observed similar age-specific frequencies, distribution of stage at diagnosis and tumor grade among cases of TNBC compared to cases of non-TNBC. Ghanaian breast cancer patients tend to have an advanced stage distribution and relatively younger age at diagnosis compared to Caucasian Americans and African Americans. The triple-negative molecular marker pattern was the most common subtype of breast cancer seen among this sample of Ghanaian women, regardless of age, tumor grade, or stage of diagnosis. Research into the molecular pathogenesis of TNBC may help elucidate the reasons for its increased prevalence among women with African ancestry.

Nephrectomy in adults: Experience at the Korle Bu Teaching Hospital, Accra, Ghana.

The objective of this study was to analyze nephrectomies performed in adults over a 12-year period at the Korle Bu Teaching Hospital, Accra and to compare our findings with reports from other institutions. In this retrospective study, medical records of 97 consecutive adult patients who underwent nephrectomy from January 2000 to December 2011 were reviewed. The parameters extracted included the patients' age, gender, indication for nephrectomy and the side of nephrectomy. Also considered were the histology of the nephrectomy specimen and the peri-operative mortality. The data were analyzed using the Statistical Package for Social Sciences for Windows (Version 19.0). Of the 97 nephrectomies performed, 62 were performed for suspected malignant renal tumors and 35 were performed for clinically benign renal conditions. Malignancy was confirmed in 85.5% (53/62) of the suspected cases. The mean age of this group was 52.2 ± 15.5 years and the male to female ratio was 1:0.9. Thirty-two tumors (60.4%) were in the right kidney and 21 (39.6%) tumors were in the left kidney; the mean tumor size was 16.8 ± 4.0 cm. The predominant presenting complaints included flank pain (67.9%), flank mass (50.9%) and hematuria (24.5%). In one case (1.9%), the renal mass was found incidentally. Among patients who had benign disease, non-functioning kidney due to renal cystic disease was the most common lesion (11/44; 25.0%). A peri-operative mortality rate of 3.1% was recorded. Our study suggests that malignant renal tumors constitute the main indication for nephrectomy in our institution. Non-functioning kidney due to renal cystic disease was the most common benign renal indication for nephrectomy.

Ovarian Cancer in Ghana, a 10 Year Histopathological Review of Cases at Korle Bu Teaching Hospital.

To determine the histopathological types, age distribution, presenting signs and symptoms of ovarian cancers diagnosed at the Korle-Bu Teaching Hospital, Ghana. All histopathology slides and request cards of ovarian cancers diagnosed over a ten-year period (2001 to 2010) were reviewed and the cancers classified according to the World Health Organization 1999 classification. Biographical and clinical data of the patients were collected and results entered into Epi-info to determine the frequency, age distribution and clinical presentation of the various types of ovarian cancer. There were 192 (27.2%) ovarian cancers out of 706 ovarian tumours. Epithelial cancers were the most common: 100 (52.1%), followed by sex cord stromal cancers 66 (34.4%). Majority of epithelial cancers were serous adenocarcinomas (71/100) while most sex cord stromal cancers were adult granulosa cell tumours 46 (69.7%). The mean age of patients with adenocarcinoma was 49 years while that of the 46 adult granulosa cell tumours was 46.5 years. Patients present with varying combinations of symptoms and signs and ovarian cancers present at an earlier age compared to other populations, with the age of presentation being slightly lower for sex cord stromal cancers compared to adenocarcinomas. There are no specific symptoms or signs associated with ovarian cancer at presentation, to assist with diagnosis.

Massive intrathoracic lipoma: a report of two cases, one being congenital.

Massive intrathoracic lipomas are uncommon. Few cases have been reported worldwide. We report two cases, one of which was congenital. They were managed by thoracotomy and complete excision, with excellent outcomes.

Clinicopathological aspects of adenocarcinoma of the large bowel in a low incidence population.

BACKGROUND AND OBJECTIVES: The presentation of the different histopathologic subtypes of adenocarcinoma of the large bowel vary within the colorectum and appears to impact on treatment. This study evaluated the relationships between the clinical features of adenocarcinoma of the large bowel, the histopathologic subtypes, and treatment. METHODS: Patients with adenocarcinoma of the large bowel presenting to the Korle Bu Teaching Hospital from January 1997 to December 2011 were studied. RESULTS: The study involved 579 patients: 310 (53.5%) males and 269 (46.5%) females, median age 58 years. Right colon cancers were 170 (29.4%), left colon 128 (22.1%), and rectum 281 (48.5%). Well-differentiated cancers were 254 (43.3%), moderately differentiated 178 (30.3%), mucinous 90 (14.8%), anaplastic 44 (7.5%), and signet-ring cell cancer 13 (2.2%). The mean ages across the histologic types were unequal, F-test 8.34, P-value 0.0005, with patients with mucinous and signet-ring cancers much younger. Mucinous cancers were predominantly in the right colon while signet-ring cell cancers were mostly in the rectum. Well- and moderately differentiated cancers presented at early stage than anaplastic and signet-ring cell cancers, P ∼ 0.01 and P < 0.03, respectively. The overall resection rate was 346 (59.8%) with rectal cancer having very low resection rate of 81 (28.8%). CONCLUSION: Adenocarcinoma of the large bowel was predominantly in the rectum and in patients who were 50 years and older and were mostly well or moderately differentiated cancers.

Breast cancer in Ghanaian women: what has changed?

OBJECTIVES: To evaluate breast cancer in Ghanaian women and to compare these findings with those of previous studies by using histopathologic data. METHODS: A review of all breast cancer specimens from January 2005 through December 2009 in our institution was conducted. RESULTS: Of 4,109 female breast specimens reviewed, 1,342 (32.7%) were malignant. Mean (SD) patient age was 50.3 (13.3) years, and mean size of the primary tumors was 4.5 cm. Eighteen (1.3%) specimens were malignant phyllodes tumors. Significant positive associations were found between size of the primary tumor and histologic type (P = .01), histologic grade (P = .001), nodal involvement (P < .001), and TNM stage (P < .001). CONCLUSIONS: More than 3 decades after the first publication of breast cancer in Ghanaian women, patients are still presenting with large clinically and histologically advanced invasive cancers.

Pregnancy outcomes among patients with sickle cell disease at Korle-Bu Teaching Hospital, Accra, Ghana: retrospective cohort study.

Pregnancy in sickle cell disease (SCD) patients is associated with increased risk of maternal and fetal mortality. This study determines pregnancy outcomes among women with SCD delivering at Korle-Bu Teaching Hospital, Accra, Ghana. Nine hundred sixty (960) medical records of pregnant women (131 HbSS, 112 HbSC, and 717 comparison group) from 2007 to 2008 were reviewed. The HbSS women were at increased risk of eclampsia (adjusted odds ratio [AOR] = 10.56, 95% confidence interval [CI] = 3.60-30.96, P < 0.001), intrauterine growth restriction (AOR = 4.00, 95% CI = 1.38-11.64, P = 0.011), and placenta previa (AOR = 22.03, 95% CI = 9.87-49.14, P < 0.001) compared with the comparison group. The HbSC women had increased risk for intrauterine fetal death (AOR = 3.38, 95% CI = 1.15-9.96, P = 0.027) and decreased risk of delivering low birth weight babies (AOR = 0.21, 95% CI = 0.06-0.73, P = 0.014). Women with SCD in Ghana are at a greater risk of morbidity and mortality in pregnancy compared with women without hemoglobinopathies. Improved maternal and fetal outcomes in Ghanaian women with SCD can be achieved through effective intervention by health care providers with thorough knowledge about predisposing factors toward adverse outcomes.

Intermittent preventive treatment with sulfadoxine-pyrimethamine against malaria and anemia in pregnant women.

The effectiveness of intermittent preventive treatment during pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) against malaria and anemia is unclear because of the spread of SP-resistant Plasmodium falciparum. This study evaluates the effectiveness of IPTp-SP among pregnant women attending the antenatal clinic at Korle-Bu Teaching Hospital in Accra, Ghana. A cross-sectional study comparing malaria and anemia prevalence among pregnant women using IPTp-SP with non-IPTp-SP users was conducted during June-August 2009. A total of 363 pregnant women (202 of IPTp users and 161 non-IPTp users) were recruited. A total of 15.3% of IPTp users had malaria compared with 44.7% of non-IPTp users (P < 0.001). A total of 58.4% of non-IPTp users were anemic compared with 22.8% of IPTp users (P < 0.001). When we controlled for other variables, the difference in the prevalence of malaria (odds ratio = 0.18, 95% confidence interval = 0.08-0.37) and anemia (odds ratio = 0.20, 95% confidence interval = 0.12-0.34) remained significant. The recommended IPTp-SP regimen is useful in preventing malaria and anemia among pregnant women in Ghana.

Cerebrospinal fluid and serum biomarkers of cerebral malaria mortality in Ghanaian children.

BACKGROUND: Plasmodium falciparum can cause a diffuse encephalopathy known as cerebral malaria (CM), a major contributor to malaria associated mortality. Despite treatment, mortality due to CM can be as high as 30% while 10% of survivors of the disease may experience short- and long-term neurological complications. The pathogenesis of CM and other forms of severe malaria is multi-factorial and appear to involve cytokine and chemokine homeostasis, inflammation and vascular injury/repair. Identification of prognostic markers that can predict CM severity will enable development of better intervention. METHODS: Postmortem serum and cerebrospinal fluid (CSF) samples were obtained within 2-4 hours of death in Ghanaian children dying of CM, severe malarial anemia (SMA), and non-malarial (NM) causes. Serum and CSF levels of 36 different biomarkers (IL-1beta, IL-1ra, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12 (p70), IL-13, IL-15, IL-17, Eotaxin, FGF basic protein, CRP, G-CSF, GM-CSF, IFN-gamma, TNF-alpha, IP-10, MCP-1 (MCAF), MIP-1alpha, MIP-1beta, RANTES, SDF-1alpha, CXCL11 (I-TAC), Fas-ligand [Fas-L], soluble Fas [sFas], sTNF-R1 (p55), sTNF-R2 (p75), MMP-9, TGF-beta1, PDGF bb and VEGF) were measured and the results compared between the 3 groups. RESULTS: After Bonferroni adjustment for other biomarkers, IP-10 was the only serum biomarker independently associated with CM mortality when compared to SMA and NM deaths. Eight CSF biomarkers (IL-1ra, IL-8, IP-10, PDGFbb, MIP-1beta, Fas-L, sTNF-R1, and sTNF-R2) were significantly elevated in CM mortality group when compared to SMA and NM deaths. Additionally, CSF IP-10/PDGFbb median ratio was statistically significantly higher in the CM group compared to SMA and NM groups. CONCLUSION: The parasite-induced local cerebral dysregulation in the production of IP-10, 1L-8, MIP-1beta, PDGFbb, IL-1ra, Fas-L, sTNF-R1, and sTNF-R2 may be involved in CM neuropathology, and their immunoassay may have potential utility in predicting mortality in CM.

Seroprevalence of human T-cell lymphotropic virus type I among pregnant women in Accra, Ghana.

Infection with human T-cell lymphotropic virus type I (HTLV-I) occurs mainly in Japan, Central and West Africa and the Caribbean Basin. Although antibody to HTLV-I has been reported among pregnant women in several endemic countries, there is no information regarding the seroprevalence in pregnant Ghanaian women. The reported seroprevalence of HTLV-I among healthy Ghanaian blood donors is between 0.5 and 4.2 %. Therefore, this study was conducted to determine the seroprevalence of HTLV-I among pregnant women attending the antenatal clinic at the 37 Military Hospital, Accra, Ghana, between the months of January and December 2003. The presence of antibodies specific for HTLV-I/II was tested using a particle agglutination test (PAT) kit and confirmed by Western blotting (WB). Of the 960 sera tested, HTLV-I/II antibodies were detected in 24 samples using the PAT kit. WB results indicated that, of the 24 positive PAT specimens, 20 specimens (83.3 %) were HTLV-I positive, one (4.2 %) was HTLV-II positive, two (8.3 %) were HTLV positive and one (4.2 %) was indeterminate. Therefore, the overall seroprevalence of HTLV-I was 2.1 %. Seroprevalence increased with age, suggesting sexual contact as the primary mode of transmission among women of childbearing age, rather than breastfeeding during infancy. The seroprevalence of 2.1 % reported here for HTLV-I in pregnant women in Accra is comparable to that of human immunodeficiency virus among the same population. In conclusion, the results indicate that HTLV-I is prevalent among asymptomatic Ghanaian pregnant women and thus there is a need to consider introducing antenatal screening for HTLV-I in Ghana.
