Selenium Deficiency as a Risk Factor for Peripartum Cardiomyopathy.

BACKGROUND: Peripartum cardiomyopathy (PPCM) is a multifactorial disease. Although the specific aetiology and pathogenesis of PPCM are unknown, several hypotheses have been proposed, including selenium deficiency. However, the risk of PPCM from selenium deficiency was not previously quantified. This posthoc analysis of peripartum cardiomyopathy in Nigeria (PEACE) registry data aimed to determine if selenium deficiency is an independent risk factor for PPCM. METHODS: Apparently healthy women who delivered within the previous 8 weeks and PPCM patients in Kano, Nigeria, were compared for selenium deficiency (<70µg/L) and other relevant socio-demographic and clinical characteristics. Selenium level was measured at recruitment for each subject. Independent predictors of PPCM were determined using logistic regression models. RESULTS: 159 PPCM patients and 90 age-matched controls were consecutively recruited. 84.9% of the patients and 3.3% of controls had selenium deficiency. Selenium deficiency independently increased the odds for PPCM by 167-fold while both unemployment and lack of formal education independently increased the odds by 3.4-fold. CONCLUSION: Selenium deficiency was highly prevalent among PPCM patients in Kano, Nigeria, and significantly increased the odds for PPCM. These results could justify screening of women in their reproductive years for selenium deficiency, particularly those living in regions with high incidence of PPCM. The results also call for the setting up of a definitive clinical trial of selenium supplementation in PPCM patients with selenium deficiency, to further define its benefits in the treatment of PPCM.

CONTEXTE: La cardiomyopathie péripartum (CMPP) est une maladie multifactorielle. Bien que l'étiologie spécifique et la pathogenèse de la CMPP soient inconnues, plusieurs hypothèses ont été proposées, notamment la carence en sélénium. Cependant, le risque de CMPP lié à la carence en sélénium n'a pas été précédemment quantifié. Cette analyse post-hoc des données du registre de la cardiomyopathie péripartum au Nigéria (PEACE) visait à déterminer si la carence en sélénium est un facteur de risque indépendant de la CMPP. MÉTHODES: Des femmes apparemment en bonne santé ayant accouché dans les 8 semaines précédentes et des patientes atteintes de CMPP à Kano, au Nigéria, ont été comparées pour la carence en sélénium (<70µg/L) et d'autres caractéristiques socio-démographiques et cliniques pertinentes. Le taux de sélénium a été mesuré au recrutement pour chaque sujet. Les prédicteurs indépendants de la CMPP ont été déterminés à l'aide de modèles de régression logistique. RÉSULTATS: 159 patientes atteintes de CMPP et 90 témoins appariés selon l'âge ont été recrutés consécutivement. 84,9% des patientes et 3,3% des témoins présentaient une carence en sélénium. La carence en sélénium augmentait indépendamment les chances de CMPP de 167 fois, tandis que le chômage et le manque d'éducation formelle augmentaient indépendamment les chances de 3,4 fois. CONCLUSION: La carence en sélénium était très répandue parmi les patientes atteintes de CMPP à Kano, au Nigéria, et augmentait significativement les chances de CMPP. Ces résultats pourraient justifier le dépistage de la carence en sélénium chez les femmes en âge de procréer, en particulier celles vivant dans des régions à forte incidence de CMPP. Les résultats appellent également à la mise en place d'un essai clinique définitif sur la supplémentation en sélénium chez les patientes atteintes de CMPP présentant une carence en sélénium, afin de définir davantage ses avantages dans le traitement de la CMPP. MOTS-CLÉS: Cardiomyopathie Péripartum; Carence en Sélénium; Facteur de Risque.

Phenotypic Characterisation of Staphylococcus aureus Isolated from Patients in Healthcare Institutions in Zaria Metropolis, Kaduna State, Nigeria.

BACKGROUND: Staphylococcus aureus is a cosmopolitan and pathogenic microorganism associated with various diseases spectra and antimicrobial resistance of public health importance. AIM: This study determined the phenotypic characteristics of S. aureus isolated from patients in healthcare institutions in Zaria metropolis. STUDY DESIGN: A cross-sectional hospital-based study was carried out in 5 healthcare institutions. Four hundred and twenty clinical samples were collected and analyzed. RESULTS: Majority of the patients (54.3%) were within the age range 21-40 years and mean age of 26.04 ± 12 years. Approximately, 70% of the respondents had history of antibiotic use prior to consultation in the hospitals and were self-prescribed, and 91.2% were outpatients. The most commonly abused antibiotics were ampicillin-cloxacillin (19.5%) and cotrimoxazole (10.0%), and the mean duration of their use was 3.5 ± 1.3 days. The detection rate for S. aureus was 10% and 5.2% for MRSA. The S. aureus isolates showed the highest frequency of resistance against ampicillin 42 (100%), followed by penicillin G 39 (92.9%) and least was to gentamicin 5 (11.9%). The frequency of resistance for the MRSA were ampicillin 22 (100%), penicillin G 21(95.5%) and least was to gentamicin 2 (9.1%). The minimum inhibitory concentrations of oxacillin were greater than 128 µg /ml. CONCLUSION: The detection rate of S. aureus and MRSA strains are of great public health concern which requires continuous health education on rational use of antibiotics among others.

CONTEXTE: Staphylococcus aureus est un micro-organisme cosmopolite et pathogène associé à divers spectres de maladies et à une résistance aux antimicrobiens d'importance pour la santé publique. OBJECTIF: Cette étude a permis de déterminer les caractéristiques phénotypiques de S. aureus isolé chez des patients dans des établissements de santé de la métropole de Zaria. PLAN DE L'ÉTUDE: Une étude transversale en milieu hospitalier a été menée dans 5 établissements de santé. Quatre cent vingt échantillons cliniques ont été recueillis et analysés. RÉSULTATS: La majorité des patients (54,3 %) étaient âgés de 21 à 40 ans et l'âge moyen était de 26,04 ± 12 ans. Environ 70 % des répondants avaient des antécédents d'utilisation d'antibiotiques avant la consultation dans les hôpitaux et étaient auto-prescrits, et 91,2 % étaient des patients externes. Les antibiotiques les plus fréquemment utilisés étaient l'ampicillinecloxacilline (19,5 %) et le cotrimoxazole (10,0 %), et la durée moyenne de leur utilisation était de 3,5 ± 1,3 jours. Le taux de détection de S. aureus était de 10 % et de 5,2 % pour le SARM. Les isolats de S. aureus ont montré la plus grande fréquence de résistance à l'ampicilline 42 (100%), suivie de la pénicilline G 39 (92,9%) et la plus faible à la gentamicine 5 (11,9%). La fréquence de résistance pour le SARM était de 22 (100%) pour l'ampicilline, 21 (95,5%) pour la pénicilline G et 2 (9,1%) pour la gentamicine. Les concentrations minimales inhibitrices de l'oxacilline étaient supérieures à 128 µg /ml. CONCLUSION: Le taux de détection des souches de S. aureus et de SARM est un grand problème de santé publique qui nécessite une éducation sanitaire continue sur l'utilisation rationnelle des antibiotiques entre autres.

A cross-sectional study of cytomegalovirus retinitis in HIV-1 infected adults in Nigeria.

BACKGROUND: Cytomegalovirus (CMV) retinitis is one of the most important opportunistic infections in HIV-infected patients in developing countries before the introduction of highly active antiretroviral therapy. In Nigerian and African HIV populations, CMV retinitis is under-reported. PATIENTS AND METHODS: In a cross-sectional study, 250 HIV-infected adults ≥18 years were recruited by systematic random sampling from March to August 2013. Using a structured questionnaire, information was obtained on socio-demographic characteristics and symptoms of visual impairment. HIV disease was staged according to the WHO clinical staging, and CD4+ T-lymphocyte count was measured. Participants with symptoms of impaired vision and/or CD4+ T-lymphocyte count <50 cells/µL had indirect ophthalmoscopic examination of the retina to detect CMV related eye lesions. RESULTS: Two hundred and fifty adults were HIV-infected, out of which 114 (46%) were males and 136 (54%) were females. The mean age of study participants was 35 years. History of impaired vision was reported by 21 (8.4%) of participants. The right eye was involved in 7 (33%), the left eye in 4 (19%), and both eyes in 10 (48%) of participants. The predominant symptoms were blurred vision 9 (43%), floaters 9 (43%), and blindness 3 (14%). Among participants who had indirect ophthalmoscopy, 3 (1.2%) had characteristic retinal changes suggestive of CMV retinitis. Two (67%) of patients with CMV retinitis were females and 1 (33%) was male. Mean CD4+ count was 25.33 ± 14.19 and all were WHO HIV clinical stage 4 with death occurring within 6 months of diagnosis. CONCLUSION: CMV retinitis though rare is associated with advanced HIV disease and attendant morbidity and mortality. We recommend integration of CMV diagnostic services and ophthalmological services as routine in HIV care and treatment programs in Nigeria targeted toward high-risk patients.

Post-renal transplant infections: single-center experience from Nigeria.

BACKGROUND: Infections are the leading cause of hospitalization and mortality in transplant recipients. Nigeria has a growing number of renal transplant recipients. The aim of this study was to determine the pattern of infections in renal allograft recipients in one of the major renal transplant centers in Nigeria. METHODS: All case records of renal allograft recipients on follow-up were retrieved. Those that had infection at any time after transplantation were selected. Demographic and clinical information was collected and analyzed. RESULTS: Thirty-three case records were analyzed, out of which 24/33 (72.7%) were males, with a mean age of 42.3 years (± 7.38). The median duration of developing infection post transplant was 270 days (range 2-2190). Most of the infections occurred after 6 months in 15/33 (45.5%). Urinary tract infection was the most common infection, noted in 13/33 (39.4%), followed by pneumonia, which was seen in 12 (33.3%), 9/12 (75%) of which were culture-positive. There were 2 cases (5.6%) of tuberculosis and 1 case (2.8%) of cytomegalovirus colitis. Out of the 9 culture-positive pneumonia cases, 6 (66.7%) were caused by gram-negative pathogens, with Pseudomonas aeruginosa being the most common isolate seen in 3/9 (33.3%) of the patients. Among those with urinary tract infection, Escherichia coli and Klebsiella species were isolated with equal proportion in 3/13 (23.1%), while Enterococcus faecalis was the most common isolate in 4/13 (30.8%). Overall infection-related mortality was 10/33 (30.3%), out of which 5/10 (50%) of deaths were from pneumonia. CONCLUSION: Post-transplant infection surveillance must be strengthened. The role of multidrug-resistant gram-negative bacteria in post-renal transplant infection in Nigeria needs to be evaluated.

Factors affecting snakebite mortality in north-eastern Nigeria.

Snakebite is an important cause of mortality among rural dwellers in the savannah region of West Africa. We conducted a retrospective review of snakebite patients managed by experienced medical staff at Kaltungo in north-eastern Nigeria to determine the cause of death. During a 36 month period there were 94 deaths among 6687 victims (1.41%). Relative risk (RR) of mortality increased to 2.29 (95% CI 1.35-3.89) during a period when source of antivenom became unreliable. The increase was not due to seasonal variation. In a logistic regression model predictors of mortality were new central nervous system (CNS) features (Odds ratio (OR) = 24.61; 95% CI 6.93-87.41) and delay from bite to hospitalization (OR for every 1 h delay = 1.01; 95% CI 1.00-1.02). Treatment with antivenom was protective (OR = 0.17; 95% CI 0.03-0.96). Relationship of anaemia and shock to mortality were not maintained following adjustment. Effort should be made to provide regionally appropriate, affordable and effective antivenoms in addition to enforcement of continuous regulatory control measures. Antivenoms should be distributed to affected areas and treatment access points of care expanded to communities to diminish travel time. The populations at risk should be educated on avoiding unnecessary delays and on prevention of bites.

Assessment of right ventricular systolic function using tricuspid annular-plane systolic excursion in Nigerians with systemic hypertension.

AIM: Right ventricular (RV) systolic function in patients with hypertensive heart disease (HHD) is not well characterised. The primary aim of this study was to assess the systolic function of the right ventricle in patients with HHD using tricuspid annular-plane systolic excursion (TAPSE). METHODS: The study was cross-sectional in design and carried out in Kano, Nigeria. Patients were recruited if they had HHD on echocardiography and were at least 15 years of age. Patients with other cardiac pathologies such as ischaemic and valvular heart diseases were excluded. Patients were considered to have abnormal RV systolic function if they had reduced values of TAPSE ( < 15 mm). A p-value of < 0.05 was considered statistically significant. RESULTS: A total of 186 patients were serially recruited over seven months. Of these, 131 (70.4%) had normal RV systolic function (group 1) and 55 patients (29.6%) had abnormal function (group 2). Group 2 patients were older (p = 0.002) and had a higher prevalence of peripheral oedema (p = 0.002), moderate to severe dyspnoea, higher heart rate and lower left ventricular ejection fraction (p < 0.001). Atrial arrhythmias were also more prevalent among group 2 patients (p < 0.05). The best correlate to TAPSE was the septal mitral annularplane systolic excursion (r = +0.541, p < 0.001). Several variables such as age predicted the presence of reduced TAPSE. CONCLUSION: The study found that almost one-third of patients with HHD in Kano had RV systolic dysfunction as defined by reduced TAPSE, and these patients had a greater prevalence of factors associated with morbidity and mortality.

Pilot study on multidrug resistant tuberculosis in Nigeria.

BACKGROUND: Drug resistant tuberculosis (TB) has lately emerged and it represents a serious public health problem. We set out to determine drug resistance among TB patients. METHODS: Using automated BACTEC cultures, multidrug resistant-tuberculosis (MDR-TB) was investigated in 117 diagnosed cases in Abuja, Nigeria. RESULTS: Ten (31%) of 32 culture-positive patients were resistant to at least one and four (13%) to all of the four drugs tested. No association between drug resistance and human immunodeficiency virus (HIV) infection was found. CONCLUSIONS: MDR-TB is present in Nigeria and larger studies are urgently required. TB clinical management and control efforts should be improved.

Amputation and disability following snakebite in Nigeria.

Snakebite is an important cause of amputation and disability in rural communities throughout the tropics. However, the details of the causes, types and estimates of disability are lacking. This report describes 16 snakebite victims who had amputations, including two who had above-knee amputations. The patients presented with limb swelling (16), gangrene (15), ischaemia (4) and three had possible compartment syndrome. All the patients used ineffective time wasting remedies that were potentially harmful as first-aid. The median delay to hospital following bite was 2.5 days. In order to prevent disability, efforts should be made to: reduce delay before hospital presentation; improve the knowledge of first-aid; provide effective antivenoms; improve wound and clinical care in communities; and improve facilities.

Pre-clinical and preliminary dose-finding and safety studies to identify candidate antivenoms for treatment of envenoming by saw-scaled or carpet vipers (Echis ocellatus) in northern Nigeria.

The aim of this study was to identify candidate antivenoms with specific activity against the venom of the saw-scaled or carpet viper (Echis ocellatus) in northern Nigeria, where bites by this species cause great morbidity and mortality but where effective antivenoms have become scarce and unaffordable. Selected antivenoms were destined to be compared by randomised controlled clinical trials (RCTs). Standard pre-clinical neutralisation assays were carried out in rodents. We included two licensed antivenoms of established clinical efficacy and 6 candidate antivenoms. Although 6 of the tested antivenoms showed promising efficacy, all but 3 were excluded from further study because of inadequate pre-clinical efficacy or because they were unavailable or unaffordable for the anticipated RCTs. Median effective doses (ED(50)) of the remaining three candidate antivenoms suggested that the following doses might neutralise the maximum observed venom yield of 24.8 mg (dry weight) of venom milked from captive E. ocellatus: 10 ml of MicroPharm "EchiTAb G" (ET-G) antivenom; 30 ml of Instituto Clodomiro Picado "EchiTAb-Plus-ICP" (ET-Plus) antivenom; 50 ml of VacSera, Cairo "EgyVac" antivenom. A preliminary clinical dose-finding and safety study of these three antivenoms was carried out in 24 patients with incoagulable blood after E. ocellatus bites who were not severely envenomed. A 3+3 dose escalation design was employed. Initial doses of 10 ml ET-G and 30 ml ET-Plus restored blood coagulability in groups of 6 patients with early mild reactions (pruritus only) in not more than one third of them. EgyVac antivenom did not fulfil efficacy or safety criteria in 12 patients. On the basis of these results, ET-G and ET-Plus were selected for comparison in a RCT.

Adherence to anti retroviral therapy (ART) during Muslim Ramadan fasting.

Annual fasting during the month of Ramadan is observed in Muslim countries, some of which have widespread HIV infection. We studied treatment adherence and customary practices among 142 fasting 'FT' and 101 non-fasting 'NFT' patients on anti-retroviral therapy (ART) in Nigeria. Adherence on ART among FT and NFT patients was similar during Ramadan, 96% and 98%, and ever since commencement of ART, 80% and 88%, respectively. FT patients altered their typical daily behaviors by advancing morning and delaying evening doses thereby prolonging dosing intervals, eating heavier meals pre-dawn and on breakfast at sunset (78%), and changing or reducing their sleeping and waking times (40%). This preliminary study suggests that adherence and drug taking frequency appear uncompromised in FT HIV infected patients on ARVs.

Response to the meningococcal meningitis epidemic (MME) at Aminu Kano Teaching Hospital, Kano (2008-2009).

In December 2008 an outbreak of Meningococcal Meningitis swept across sub Saharan Africa with Nigeria, especially its northern states worst affected. The management of Aminu Kano Teaching Hospital constituted an Emergency Preparedness & Response (EPR) committee. Over the course of 18 weeks from 5 January 2009 to 15 May 2009, AKTH managed 222 cases of suspected meningitis with 14 deaths (case fatality rate [CFR] of 6.3%). Twenty three per cent (23%) were microbiologically proven as meningococcal meningitis while 9% were confirmed to be pneumococcal meningitis. Male to female ratio was 1:1 with most patients (81%) aged below 14 years. The epidemic peaked in weeks 10 and 13 with 38 admissions in the respective weeks. Meningococcemia with purpura fulminans, post meningitic immune complex cutaneous vasculitis and polyarthritis were observed. Control measures instituted included provision of free ceftriaxone, chemoprophylaxis to contacts, vaccines to staff/families, and creation of dedicated isolation wards. Clinical management guidelines were developed and hospital staffs were also enlightened. Lessons learnt included the difficulty of discriminating between nosocomial transmission and community clusters; relative increase in pneumococcal meningitis during the epidemic; unreliability of penicillin/chloramphenicol; the utility of internet for communication; and the inadequacy of vaccines to meet staff & public demand.

Pattern of Left Ventricular Geometry in Hypertension: a Study of a Hypertensive Population in Nigeria

Background: Hypertension is a leading cause of cardioxasular morbidity and mortality in Nigeria. The main aim of this study was to deterine the prevalence of left ventricular hypertrophy and left ventricular geometric patterns among hypertensives in Kano; Nigeria. Methods: The study was cross-sectional in design; and carried out in 3 echocardiography laboratories within the City of Kano; Nigeria. Patients with hypertension without other cardiac disorders were serially recruited and studied after obtaining informed consent. Results: A total of 186 patients were studied over 7 months; 89 males (47.9) and 97 females (52.1). The prevalence of left ventricular hypertrophy was 61.8. Thirty five patients (18.8) had normal left ventricular geometry and these were predominantly females and had the lowest mean age and shortest duration of hypertension. Sixty eight patients (36.6) had eccentric hypertrophy; 47 (25.3) had concentric hypertrophy and 36 (19.4) had concentric remodelling. Independent predictors of the various geometric patterns were identified. Conclusion: A high prevalence of left ventricular hypertrophy was observed with eccentric hypertrophy being the most common geometric pattern. Gender influenced the pattern of left ventricular geometry

Envenoming after carpet viper (Echis ocellatus) bite during pregnancy: timely use of effective antivenom improves maternal and foetal outcomes.

The report describes successful management of 10 women in 2nd and 3rd pregnancy trimesters with EchiTab IgG antivenom after carpet viper (Echis ocellatus) envenoming. All women survived but foetal loss in a victim with delayed presentation and a case of mild hypersensitivity reaction were recorded. Excellent outcomes can be achieved in rural and semi-nomadic populations without specialized care and immediate access and provision of effective antivenoms is paramount in curtailing snakebite maternal morbidity, mortality and foetal loss.

Migration; Pastoralists; HIV Infection and Access to Care: the Nomadic Fulani of Northern Nigeria

The burden of HIV infection among the nomadic Fulani of northern Nigeria is unknown. Migration - a way of life for this population - is known to increase the rate of HIV transmission and may limit individuals' access to treatment and care. Many of Africa's other traditional; pastoral societies are similarly affected. This paper explores cultural practices and factors among the Fulani that may influence HIV transmission; vulnerability to infection; sustainability and challenges to treatment access; and avenues and models for outreach services; lastly; we proffer some solutions and recommendations. An extensive literature search with cross-referencing was done; and relevant publications on similar themes were reviewed. Three cases of Fulani nomads with HIV are presented to illustrate the challenge of providing a care continuum as well as to demonstrate successes when appropriate HIV interventions are employed. Patient interviews provide valuable insight and information on living and coping with HIV. Community mobility limits opportunities for counselling; testing and diagnosis; as well as HIV-related care access and maintenance. Consanguinity and certain cultural practices among the Fulani have clear amplification potential for HIV transmission. Treatment support through the use of coaches and life partners improves adherence to antiretroviral therapy (ART). Existing programmes for nomads afford opportunities for absorption and integration of HIV services. Nomadic communities should be provided with basic HIV-related services; including risk-reduction education and methods; counselling and testing; ART; medication adherence counselling; access to laboratory tests and health monitoring. These services should be taken to nomadic communities using novel approaches such as mobile units; extension services; case management; directly observed care; and treatment supporters linked to neighbouring health facilities in a hub-and-spoke model. Stronger collaborations are recommended between programmes for nomads and HIV services; and also between veterinary and public health services. Community participation and leadership should be encouraged to ensure the sustainability of HIV-related care delivery. More research is needed on the epidemiology and sociology of HIV infection and the best ways to provide services to hard-to-reach nomadic populations

A clinical audit of presentation and outcome of Salmonella septicaemia.

INTRODUCTION: Enteric fever is imported to developed countries while non-typhoidal salmonella infections occur globally. Clinicians and trainees need to recognise the varied presentations of serious salmonella infections. MATERIALS AND METHODS: We reviewed the clinical presentations, hospital course, complications and outcomes of 50 patients who were blood culture positive for Salmonella spp seen in 2 years. RESULTS: Nineteen of 24 patients with enteric fever had recently travelled to Asian countries. All the enteric fever patients recovered fully. Out of 26 patients with non-typhoidal salmonellosis, 10 had malignancies, 7 had immune dysfunction states and 3 had aortic aneurysms. Five patients had recurrent episodes of salmonellosis. Eight of these patients who had cancer (4), diabetes mellitus with renal failure (2) and gastric diseases (2) died. Fatal cases were older with multiple admissions and co-morbidities (median, 3) and presentation followed immunosuppressive interventions, often with no fever (4). Onset was sudden with a short and fatally unresponsive course despite effective antimicrobial agents with microbiologic diagnosis made posthumously (4). Death resulted rapidly from overwhelming sepsis and aneurysmal complications. Antibiotic resistance to ampicillin, cotrimoxazole and chloramphenicol was noted. CONCLUSION: Enteric fever should be considered in travellers returning from Asian countries with fever, and third-generation cephalosporins or quinolones should be used for empiric treatment. Given the presentation of non-typhoidal salmonella septicaemias, clinicians need to have a high index of suspicion and to consider preemptive therapy in patients with prior infection who are likely to develop severe immunosuppression following interventions.
