Frailty syndrome and associated factors among patients with hypertension: A cross-sectional study in Kumasi, Ghana.

Background and Aim: Frailty is a condition marked by accumulation of biological deficits and dysfunctions that come with aging and it is correlated with high morbidity and mortality in patients with cardiovascular diseases, particularly hypertension. Hypertension continues to be a leading cause of cardiovascular diseases and premature death globally. However, there is dearth of literature in sub-Saharan Africa on frailty syndrome among hypertensives on medication. This study evaluated frailty syndrome and its associated factors among Ghanaian hypertensives. Methods: This cross-sectional study recruited 303 patients with hypertension from the University Hospital, Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. Data on sociodemographic, lifestyle and clinical factors were collected using a well-structured questionnaire. Medication adherence was measured using Adherence in Chronic Disease Scale, and frailty was assessed by Tilburg Frailty Indicator. Statistical analyses were performed using SPSS Version 26.0 and GraphPad prism 8.0. p-value of < 0.05 and 95% confidence interval (CI) were considered statistically significant. Results: The prevalence of frailty was 59.7%. The proportion of high, medium and low medication adherence was 23.4%, 64.4% and 12.2%, respectively. Being ≥ 70years (adjusted odds ratio [aOR]: 8.33, 95% CI [3.72-18.67], p < 0.0001), unmarried (aOR: 2.59, 95% CI [1.37-4.89], p = 0.0030), having confirmed hypertension complications (aOR: 3.21, 95% CI [1.36-7.53], p = 0.0080), medium (aOR: 1.99, 95% CI [1.05-3.82], p = 0.0360) and low antihypertensive drug adherence (aOR: 27.69, 95% CI [7.05-108.69], p < 0.0001) were independent predictors of increased odds of developing frailty syndrome. Conclusion: Approximately 6 out of 10 Ghanaian adult patients with hypertension experience frailty syndrome. Hypertension complications, older age, being unmarried, and low antihypertensive drug adherence increased the chances of developing frailty syndrome. These should be considered in intervention programmes to prevent frailty among patients with hypertension.

Profiling vitamin D, its mediators and proinflammatory cytokines in rheumatoid arthritis: A case-control study.

INTRODUCTION: The active form of vitamin D has immunomodulatory and anti-inflammatory effect. Vitamin D is implicated in pathogenesis of rheumatoid arthritis (RA) and its deficiency leads to increased inflammation. Moreover, its production is dependent on concentration of calcium, phosphorus, and parathyroid hormone (PTH). Cytokines mediates inflammation in RA synovium. This study evaluated vitamin D, its mediators and proinflammatory cytokines among RA patients. METHODS: In a case-control study, 78 RA patients from Komfo Anokye Teaching Hospital rheumatology clinic and 60 healthy blood donors were recruited. Chemistry analyzer and enzyme-linked immunosorbent assay kits were used to measure biochemical parameters and cytokines. RESULTS: We found significantly higher levels of interleukin (IL)-1ß, interferon gamma (IFN-γ), and tumor necrosis factor-α (TNF-α) in RA patients compared with controls (p < .05). There was a significant positive correlation between intact parathyroid hormone (iPTH) and IL-10 (r = .30, p < .05) and a negative correlation between IL-6 (r = -0.28, p > .05), IL-1ß (r = -0.25, p > .05), TNF-α (r = -0.26, p > .05), IFN-γ (r = -0.24, p > .05), and iPTH. There was a significant negative correlation between IL-1ß (r = -0.33, p < .05), IFN- γ (r = -0.29, p < .05), and calcium. CONCLUSION: Reduced PTH, calcium, and phosphorus is associated with higher levels of proinflammatory cytokines which may worsen RA disease condition. Vitamin D is therefore not an independent regulator of proinflammatory cytokines in RA.

Assessing the role of eosinophil-mediated immune response markers in detecting hookworm infection: A case-control study in Kintampo, Ghana.

Background and Aim: Human hookworm disease caused by Ancylostoma duodenale and Necator americanus is a serious public health problem. Hookworm infection activates eosinophil-mediated tissue inflammatory responses, involving the production of the eosinophil-specific chemokine (eotaxin), recruitment of eosinophils, secretion of the cationic protein, and production of antiparasite immunoglobulin E (IgE). We investigated eosinophil-mediated immune response as markers (CCL11, eosinophil cationic protein [ECP], and IgE) for detecting hookworm infection. Methods: This case-control study was carried out in hookworm endemic areas within the Kintampo North Municipality.Forty hookworm-positive subjects and 36 apparently healthy individuals were recruited as cases and controls, respectively. Stool samples were collected for hookworm detection by the Kato-Katz technique and speciation by polymerase chain reaction. Approximately, 5 ml of intravenous blood was used to obtain plasma for the immunological assays. Results: Of eosinophil-mediated immune response markers studied, ECP and CCL11 were significantly higher among hookworm patients compared to controls. Increasing CCL11 (ß = -0.81, p = 0.015) was associated with a significant decrease hookworm intensity. However, increasing eosinophil count (ß = 0.62, p = 0.027) was associated with significant increase in hookworm intensity. In receiver operator characteristics analysis, ECP could significantly detect hookworm infection with a very high area under the curve (AUC) (AUC = 0.97, p < 0.0001). At a cutoff of 39.05, ECP was the best eosinophil-mediated immune response marker for detecting hookworm infection with a sensitivity of 97.2%, specificity of 87.8%, a positive predictive value of 89.7%, and a negative predictive value of 96.6%. Conclusion: ECP best predicts eosinophil-mediated immune response for detecting hookworm infection, while CCL11 and eosinophil count better predict the intensity of hookworm. Moreover, the ECP level is a good indicator of hookworm infection and intensity and may require additional investigations to augment current hookworm diagnostic techniques.

Plasmodium falciparum coinfection is associated with improved IgE and IgG3 response against hookworm antigens.

Background: Plasmodium falciparum and Hookworm infections are prevalent in West Africa and they cause iron deficiency anemia and protein malnutrition in Children. Immune response of these parasites interact and their interactions could have repercussions on vaccine development and efficacy. The current goal of hookworm eradication lies on vaccination. We evaluated the effect of P. falciparum coinfection and albendazole treatment on naturally acquired antibody profile against hookworm L3 stage larvae antigen. Methods: In a longitudinal study, 40 individuals infected with Necator americanus only, 63 participants infected with N. americanus and P. falciparum, and 36 nonendemic controls (NECs) were recruited. The study was done in the Kintampo North Metropolis of Ghana. Stool and blood samples were taken for laboratory analyses. Serum samples were obtained before hookworm treatment and 3 weeks after treatment. Results: The malaria-hookworm (N. americanus and P. falciparum) coinfected subjects had significantly higher levels of IgE (ß = 0.30, 95% CI = [0.12, 0.48], p = 0.023) and IgG3 (ß = 0.15, 95% CI = [0.02, 0.52], p = 0.004) compared to those infected with hookworm only (N. americanus). The N. americanus groups had significantly higher levels of IgG3 (ß = 0.39, 95% CI = [0.14-0.62], p = 0.002) compared to the control group. Similarly, N. americanus and P. falciparum coinfected participants had significantly higher levels of IgE (ß = 0.35, 95% CI = [0.70-0.39], p = 0.002) and IgG3 (ß = 0.54, 95% CI = [0.22-0.76], p = 0.002). Moreover, albendazole treatment led to a significant reduction in IgE, IgA, IgM, and IgG3 antibodies against hookworm L3 stage larvae (p < 0.05). Conclusion: P. falciparum is associated with improved IgE and IgG response against hookworm L3 stage larvae. Treatment with single dose of albendazole led to reduction in naturally acquired immune response against hookworm infection. Thus, P. falciparum infection may have a boosting effect on hookworm vaccine effectiveness.

Increased metformin dosage suppresses pro-inflammatory cytokine levels in systemic circulation and might contribute to its beneficial effects.

Type 2 Diabetes Mellitus (T2DM) is a metabolic disorder, characterized by persistent elevation of blood glucose either due to insulin resistance or insulin insufficiency. Metformin is the recommended first choice of drug for the management of T2DM and is known to improve insulin sensitivity and prevents hyperglycemia by reducing chronic inflammation. T-helper type 1 (Th1) and type 17 (Th17) cells, are important pro-inflammatory CD4+ T cell subsets secreting TNF-α, and INF-γ (Th1), and interleukin 17 (Th17). These cytokines have been shown to play a crucial role in inflammation, insulin resistance, and the development of T2DM. Here, we explore the effect of different metformin dosages on pro-inflammatory cytokine (TNF-α, INF-γ, GM-CSF and IL-17) levels in systemic circulation among T2DM patients in Ghana, since inflammatory responses and cytokines play significant roles in the pathogenesis and progression of T2DM patients on metformin. Two hundred and nine (209) consenting T2DM patients receiving treatment at the Diabetic unit of the Komfo Anokye Teaching Hospital (KATH) in the Ashanti region of Ghana were recruited in a hospital-based cross-sectional study design. Blood samples were collected and serum obtained from each participant were analyzed for the concentrations of TNF-α, INF-γ, GM-CSF and IL-17 cytokine levels by solid-phase sandwich ELISA. We observed that participants on 3000 mg/day dose of metformin had significantly lower levels of TNF-α (p < .001) and IFN-γ (p = .014) compared to those on other dosages (1000 mg and 2000 mg/day). However, GM-CSF and IL-17 levels were not affected by increased metformin dosages. After adjusting for age, gender, dose and duration of metformin use, we observed that participants who took higher doses of metformin had significantly reduced levels of TNF-α (ß = -0.0297, 95% CI = (-0.005 to -0.002) p < .001. Metformin dosage independently predicted reduced TNF-α levels with 14.4% variations in the metformin dosage levels. Increased metformin dosage suppresses TNF-α levels in systemic circulation and hence might contribute to its beneficial effects.

Acute kidney injury in pediatric patients with malaria: A prospective cross-sectional study in the shai-osudoku district of Ghana.

Acute kidney injury (AKI) is a highly fatal complication of malaria. We used the Kidney Disease Improving Global Outcomes (KDIGO) and Pediatric Risk, Injury, Failure, Loss, End-Stage Kidney Disease (pRIFLE) guidelines to assess AKI among children. One hundred children with Plasmodium falciparum malaria were recruited from the St. Andrew's Catholic Hospital. Admission and 48-h serum creatinine were estimated. Weight and height of the participants were measured, and AKI status determined with the KDIGO and pRIFLE guidelines. A questionnaire was used to collect the socio-demographic and clinical data of participants. Two percent and 5% of the participants had AKI according to the KDIGO and pRIFLE criteria, respectively. Per the KDIGO guidelines, 1% of the participants had Stage 2 and 1% also had Stage 3 AKI. Four percent had Stage 1 (risk) and 1% had Stage 2 (injury) AKI per the pRIFLE criteria. Participants with AKI were dehydrated, and neither had sepsis or on antibiotics when the KDIGO guideline was used. Participants who had AKI were dehydrated, with 80% having sepsis and 40% on antibiotics when the pRIFLE criteria were used. There was no association between the KDIGO and pRIFLE criteria with respect to AKI status of participants (k = -0.029, P = 0.743). Two percent and 5% of the study participants had AKI when the KDIGO and pRIFLE guidelines were used respectively. One percent of the participants had Stage 2 and 1% also had Stage 3 AKI per KDIGO; 4% had Stage 1 (risk) and 1% had Stage 2 (injury) AKI per the pRIFLE.

RNA Aptamer That Specifically Binds to Mycolactone and Serves as a Diagnostic Tool for Diagnosis of Buruli Ulcer.

BACKGROUND: Buruli ulcer (BU) is a subcutaneous skin disease listed among the neglected tropical diseases by the World Health Organization (WHO). Early case detection and management is very important to reduce morbidity and the accompanied characteristic disfiguring nature of BU. Since diagnosis based on clinical evidence can lead to misdiagnosis, microbiological confirmation is essential to reduce abuse of drugs; since the anti-mycobacterial drugs are also used for TB treatment. The current WHO gold standard PCR method is expensive, requires infrastructure and expertise are usually not available at the peripheral centers where BU cases are managed. Thus one of the main research agendas is to develop methods that can be applied at the point of care. In this study we selected aptamers, which are emerging novel class of detection molecules, for detecting mycolactone, the first to be conducted in a BUD endemic country. METHODS: Aptamers that bind to mycolactone were isolated by the SELEX process. To measure their affinity and specificity to mycolactone, the selected aptamers were screened by means of isothermal titration calorimetry (ITC) and an enzyme-linked oligonucleotide assay (ELONA). Selected aptamers were assessed by ELONA using swab samples from forty-one suspected BU patients with IS2404 PCR and culture as standard methods. ROC analysis was used to evaluate their accuracy and cutoff-points. RESULTS: Five out of the nine selected aptamers bound significantly (p< 0.05) to mycolactone, of these, three were able to distinguish between mycolactone producing mycobacteria, M. marinum (CC240299, Israel) and other bacteria whilst two others also bounded significantly to Mycobacterium smegmatis. Their dissociation constants were in the micro-molar range. At 95% confidence interval, the ROC curve analysis among the aptamers at OD450 ranged from 0.5-0.7. Using this cut-off for the ELONA assay, the aptamers had 100% specificity and sensitivity between 0.0% and 50.0%. The most promising aptamer, Apt-3683 showed a discernible cleavage difference relative to the non-specific autocatalysis over a 3-minute time course. CONCLUSION: This preliminary proof-of-concept indicates that diagnosis of BUD with RNA aptamers is feasible and can be used as point of care upon incorporation into a diagnostic platform.

Clinical and Laboratory Diagnosis of Buruli Ulcer Disease: A Systematic Review.

Background. Buruli ulcer (BU) is a necrotizing cutaneous infection caused by Mycobacterium ulcerans. Early diagnosis is crucial to prevent morbid effects and misuse of drugs. We review developments in laboratory diagnosis of BU, discuss limitations of available diagnostic methods, and give a perspective on the potential of using aptamers as point-of-care. Methods. Information for this review was searched through PubMed, web of knowledge, and identified data up to December 2015. References from relevant articles and reports from WHO Annual Meeting of the Global Buruli Ulcer initiative were also used. Finally, 59 articles were used. Results. The main laboratory methods for BU diagnosis are microscopy, culture, PCR, and histopathology. Microscopy and PCR are used routinely for diagnosis. PCR targeting IS2404 is the gold standard for laboratory confirmation. Culture remains the only method that detects viable bacilli, used for diagnosing relapse and accrued isolates for epidemiological investigation as well as monitoring drug resistance. Laboratory confirmation is done at centers distant from endemic communities reducing confirmation to a quality assurance. Conclusions. Current efforts aimed at developing point-of-care diagnostics are saddled with major drawbacks; we, however, postulate that selection of aptamers against MU target can be used as point of care.

Assessment of the RIFLE criteria for the diagnosis of Acute Kidney Injury; a retrospective study in South-Western Ghana.

BACKGROUND: Acute kidney injury (AKI) affects 3-7 % of patients admitted to the hospital and approximately 25-30 % of patients in the intensive care unit. RIFLE, a newly developed international consensus classification for AKI, defines three grades of severity-class R (risk), I (injury) and F (failure). The aim of this study was to evaluate whether the RIFLE system of classification can detect the incidence of AKI using retrospective data of in-patients at the Effia-Nkwanta Regional Hospital. METHODS: A total of 1070 in-patients' records spanning a period of 6 months, from July 2014 to December 2014, was used. Demographic data and hospital admission serum creatinine of each participant were used for the calculation of estimated glomerular filtration rate (eGFR) using the 4-variable modification of diet in renal disease (MDRD) equation. Also, the baseline serum creatinine was estimated assuming a standard GFR of 75 ml/min/1.73 m(2) using the simplified MDRD equation. RESULTS: Males had higher serum creatinine, eGFR, and baseline serum creatinine than females (P < 0.0001). However, the level of increase in baseline serum creatinine was higher in females than males (P = 0.0212). The percentage ratios of the various classes from the SCr/ePCr (hospital admission serum creatinine/estimated plasma creatinine) criteria (R-1.45, I-1.53 and F-3.26) were higher than that of the eGFR criteria (R-0.34, I-0.11, F-0.12). The SCr/ePCr criteria gave more risk (89.7 %) than that of the eGFR criteria (23.1 %). The number of Injury and normal patients from the eGFR criteria was higher than the SCr/ePCr criteria. CONCLUSION: AKI was common in the ICU population with SCr/ePCr detecting more AKI than the eGFR criteria. Males had more injury and failure than females using the eGFR criteria whereas the SCr/ePCr gave females more risk and injury than males. A prospective cohort study must be employed in subsequent studies using the RIFLE criteria to assess the incidence of AKI in hospitalized patients with known diseases or medical conditions.

Seroconversion of Hepatitis B Vaccine in Young Children in the Kassena Nankana District of Ghana: A Cross-Sectional Study.

BACKGROUND: Hepatitis B Virus (HBV) infection is an important public health problem that requires high priority efforts towards prevention and control. Active immunization is the single most important and effective preventive measure against HBV infection. As a protective measure, Ghana introduced the mass immunization program against hepatitis B infection in children in 2002 in her Expanded Programme on Immunization (EPI). This study evaluated seroconversion (the point in time when the amount of antibody in the blood becomes detectable) and seroprotection (the point in time when the amount of antibody in the blood is enough to confer protection from the antigen that induced it production) status of children under this mass immunization program and measured their antibody levels five years after immunization. MATERIALS AND METHOD: 200 archived plasma samples of children between the ages of 1-10 years were retrieved from a previous cross-sectional study by researchers from NHRC between 2009 and 2010. Of these, 104 have completed the EPI and were screened for HBsAg. Those found to be HBsAg-seronegative were stratified into three groups according to their age at which the last vaccine was administered. Their anti-HBsAg titer levels were estimated by enzyme linked immunosorbant assay (ELISA). RESULTS: Two (1.9%) samples were HBsAg seropositive and were excluded from further analyses. 10 more samples were excluded from analyses because they were insufficient. The anti-HBs titers recorded ranged from 1.021 IU/L to 751.64 IU/L indicating a 100% seroconversion rate. In group one (0-6 months), 87.9% were seroprotected. Group two (2-3yrs) had 78.3% seroprotection and group three (3-5yrs) had 41.7% seroprotection. There was no significant difference between group 1 and 2. However, there was a significant difference between group 1 and 3 (p = 0.0137) and between group 2 and 3 (p = 0.0390) respectively. There was no significant difference between male and female children. CONCLUSION: All the children who received doses of hepatitis B vaccine at 6, 10 and 14 weeks in the immunization program seroconverted, but their levels of protection waned with increasing years. Booster doses are therefore recommended after 5 years.

Prevalence of chronic kidney disease among the high risk population in South-Western Ghana; a cross sectional study.

BACKGROUND: Chronic Kidney Disease (CKD) is a major global health problem. CKD is one of the most common complications of diabetes mellitus and hypertension and carries a risk of cardiovascular morbidity and mortality and progression to end-stage kidney disease. OBJECTIVES: This study sought to use the 2012 Kidney Disease Improving Global Outcomes (KDIGO) definitions to establish the prevalence and risk factors for CKD among a high risk population in the Sekondi-Takoradi metropolis. DESIGN: Cross sectional study. SETTING: Effia-Nkwanta regional and the Takoradi Government hospitals in South Western Ghana. PATIENTS: Two hundred eight consecutive adults with diabetes, hypertension or both. MEASUREMENTS: Serum creatinine and urine albumin-creatinine ratio respectively. The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) was used to estimate glomerular filtration rate (GFR). METHODS: CKD was classified according to KDIGO. RESULTS: The prevalence of CKD was 30 %: 27 % in patients with diabetes, 22 % in patients with hypertension only and 74 % in patients with both diabetes and hypertension. GFR category G3a CKD was most prevalent stage (9 %). Albuminuria was highest among people with diabetes (39 %). LIMITATIONS: A convenience sample of patients attending clinics. CONCLUSION: CKD was prevalent in these high-risk patients.

CONTEXTE: L'insuffisance rénale chronique (IRC) est un problème majeur de santé globale. Elle se révèle l'une des plus fréquentes complications du diabète sucré et de l'hypertension. De plus, l'IRC pose un risque accru pour les patients de souffrir, voire de mourir de cardiopathie, ou alors de voir leur état progresser vers l'insuffisance rénale terminale. OBJECTIFS DE L'ÉTUDE: L'étude a cherché à établir la prévalence et les facteurs de risque de l'IRC dans la population prédisposée de la métropole de Sekondi-Takoradi (Ghana) en utilisant les définitions proposées par « Kidney Disease Improving Global Outcomes ¼ (KDIGO) en 2012. TYPE D'ÉTUDE: Il s'agit d'une étude transversale. CONTEXTE DE L'ÉTUDE: L'étude a été effectuée sur des patients de l'hôpital régional Effia-Nkwanta et de l'hôpital gouvernemental de Takoradi, dans le sud-ouest du Ghana. PATIENTS: L'étude était constituée d'une cohorte de 208 adultes atteints de diabète, d'hypertension ou d'une comorbidité. MESURES: Le rapport albumine-créatinine dans l'urine ainsi que le taux de créatinine sérique ont été mesurés, puis le débit de filtration glomérulaire (GFR) a été déterminé à l'aide de l'équation du « Chronic Kidney Disease Epidemiology Collaboration ¼ (CKD-EPI). MÉTHODOLOGIE: L'IRC a été déterminée selon les critères de KDIGO. RÉSULTATS: À la suite de cette étude, la prévalence d'IRC a été établie à 30 % parmi les patients de la cohorte. Elle s'établissait à 27 % chez les patients atteints de diabète seulement, 22 % chez les patients atteints d'hypertension seulement et de 74 % chez les patients présentant à la fois du diabète et de l'hypertension. Le stade d'IRC (9 %) le plus prévalent était de catégorie G3a. La prévalence d'albuminurie était plus élevée chez les patients diabétiques (39 %). LIMITES DE L'ÉTUDE: Il s'agit d'un échantillon de commodité formé de patients fréquentant les deux cliniques mentionnées plus haut. CONCLUSIONS: La prévalence d'insuffisance rénale chronique était plus élevée chez ce groupe de patients considérés à haut risque.

Association between adverse pregnancy outcome and imbalance in angiogenic regulators and oxidative stress biomarkers in gestational hypertension and preeclampsia.

BACKGROUND: Gestational hypertension (GH) and Preeclampsia, (PE) are the most complicated amongst hypertensive disorders of pregnancy. The mechanism that links hypertension in pregnancy to adverse maternal outcomes is not fully understood though some relate this to endothelial dysfunction originating from an imbalanced angiogenic regulators and oxidative stress biomarkers. This study assessed the correlation between angiogenic regulators and oxidative stress biomarker levels with adverse pregnancy outcomes among GH and PE participants. METHODS: A cohort of pregnant women who received antenatal care at the Obstetrics and Gynaecology department of the Komfo Anokye Teaching Hospital (KATH) were followed. During their antenatal visits, 100 developed PE and 70 developed GE, of these, 50 PE and 50 GH gave informed consent. Their blood samples were taken at time of diagnosis and 48 h post-partum. 50 other aged-matched women who did not develop neither GH nor PE were selected as controls. Placental growth factor (PLGF), soluble fms-like tyrosine kinase 1 (sFlt-1) and 8-epi-prostaglandin F2alpha (8-epi-PGF2α) levels were estimated by ELISA and total antioxidant capacity (T-AOC) was measured spectrophotometrically. Graphpad Prism was used for data analysis. RESULTS: Median levels of sFlt-1, 8-epi-PGF2α and sFlt-1/PLGF were elevated among participants with PE co-existing with intrauterine fetal death (IUFD), placental abruptio, placental previa, HELLP syndrome and intrauterine growth restriction (IUGR) compared to PE without adverse outcomes (p = 0.041, p = 0.005, p = 0.0002). Levels of PLGF, T-AOC and PLGF/sFlt-1 were significantly reduced among participants with PE co-existing with IUFD, placental abruptio, placental previa, HELLP syndrome and IUGR compared to PE without adverse outcomes (p = 0.0013, p = 0.006, p < 0.0001). A significant negative correlation of IUGR (p = 0.0030; p < 0.0001), placental abruptio (p < 0.0001; p < 0.0001), IUFD (p < 0.0001; p < 0.0001), stillbirth (p = 0.0183 and p < 0.000), and postpartum haemorrhage (PPH) (p = 0.0420; p = 0.0044) were associated with both PLGF and T-AOC whilst a significant positive correlation of IUGR, placental abruptio (p < 0.0001; p < 0.0001), IUFD (p < 0.0001; p < 0.0001), stillbirth (p < 0.0001; p < 0.0001), and PPH (p = 0.0043; p = 0.0039) were observed with both sFlt-1 and 8-epi-PGF2α in PE. CONCLUSIONS: Imbalance in the levels of angiogenic regulators and oxidative stress biomarkers correlates with adverse pregnancy outcomes among PE participants. Early identification of these imbalance would alert health care givers in anticipation of adverse pregnancy outcome and thus increased surveillance during pregnancy and parturition and measures to ameliorate the adverse outcome.

Microhaematuria as a diagnostic marker of Schistosoma haematobium in an outpatient clinical setting: results from a cross-sectional study in rural Ghana.

The utility of microhaematuria (as measured by urine reagent strips) as a surrogate marker for Schistosoma haematobium infection is not established in patients with urogenital symptoms presenting to clinical settings, although previous studies have demonstrated its utility in screening asymptomatic individuals in large community or school-based settings. In this cross-sectional study of 201 patients, multivariate analysis demonstrated microhaematuria as an independent predictor of S. haematobium infection (OR, 4.29; 95% CI, 1.6-11.9) in individuals presenting with urogenital symptoms to an outpatient medical department (OPD) at a rural Ghanaian medical center. Microhaematuria is predictive of S. haematobium infections in clinical settings in endemic regions.

Seroprevalence and risk factors of Hepatitis B and Hepatitis C infections among pregnant women in the Asante Akim North Municipality of the Ashanti region, Ghana; a cross sectional study.

BACKGROUND: Viral hepatitis is a serious public health problem affecting billions of people globally with maternal-fetal transmission on the rise. OBJECTIVES: This study sought to determine the prevalence and factors associated with hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among pregnant women in the Asante Akim North Municipality, in the Ashanti region of Ghana. METHODS: In this cross-sectional study 168 pregnant women were recruited from the Agogo Presbyterian hospital. Blood samples were collected for the detection of Hepatitis B Surface Antigen (HBsAg) and anti-HCV antibodies. A pretested questionnaire was used to obtain demographic data and identify the risk factors associated with the two infections. RESULTS: Of the 168 participants studied, 16 (9.5%) tested positive for HBV and 13 (7.7%) tested positive for HCV representing 9.5% and 7.7% respectively. A participant tested positive for both HBV and HCV co-infection representing 0.6%. Undertaking blood transfusion, tattooing and sharing of needles were associated with hepatitis C infection (P=0.001). HBV was not associated with any of the risk factors (P>0.05). CONCLUSION: Our findings suggest a high prevalence of hepatitis B and hepatitis C among pregnant women; blood transfusion, tattooing and sharing of hypodermic needles were associated with hepatitis C infection. Measures to reduce the disease and transmission burden must be introduced.
