RESUMO

BACKGROUND: Subclinical pulmonary tuberculosis, which presents without recognisable symptoms, is frequently detected in community screening. However, the disease category is poorly clinically defined. We explored the prevalence of subclinical pulmonary tuberculosis according to different case definitions. METHODS: We did a one-stage individual participant data meta-analysis of nationally representative surveys that were conducted in countries with high incidence of tuberculosis between 2007 and 2020, that reported the prevalence of pulmonary tuberculosis based on chest x-ray and symptom screening in participants aged 15 years and older. Screening and diagnostic criteria were standardised across the surveys, and tuberculosis was defined by positive Mycobacterium tuberculosis sputum culture. We estimated proportions of subclinical tuberculosis for three case definitions: no persistent cough (ie, duration ≥2 weeks), no cough at all, and no symptoms (ie, absence of cough, fever, chest pain, night sweats, and weight loss), both unadjusted and adjusted for false-negative chest x-rays and uninterpretable culture results. FINDINGS: We identified 34 surveys, of which 31 were eligible. Individual participant data were obtained and included for 12 surveys (620 682 participants) across eight countries in Africa and four in Asia. Data on 602 863 participants were analysed, of whom 1944 had tuberculosis. The unadjusted proportion of subclinical tuberculosis was 59·1% (n=1149/1944; 95% CI 55·8-62·3) for no persistent cough and 39·8% (773/1944; 36·6-43·0) for no cough of any duration. The adjusted proportions were 82·8% (95% CI 78·6-86·6) for no persistent cough and 62·5% (56·6-68·7) for no cough at all. In a subset of four surveys, the proportion of participants with tuberculosis but without any symptoms was 20·3% (n=111/547; 95% CI 15·5-25·1) before adjustment and 27·7% (95% CI 21·0-36·4) after adjustment. Tuberculosis without cough, irrespective of its duration, was more frequent among women (no persistent cough: adjusted odds ratio 0·79, 95% CI 0·63-0·97; no cough: adjusted odds ratio 0·76, 95% CI 0·62-0·93). Among participants with tuberculosis, 29·1% (95% CI 25·2-33·3) of those without persistent cough and 23·1% (18·8-27·4) of those without any cough had positive smear examinations. INTERPRETATION: The majority of people in the community who have pulmonary tuberculosis do not report cough, a quarter report no tuberculosis-suggestive symptoms at all, and a quarter of those not reporting any cough have positive sputum smears, suggesting infectiousness. In high-incidence settings, subclinical tuberculosis could contribute considerably to the tuberculosis burden and to Mycobacterium tuberculosis transmission.

RESUMO

OBJECTIVES: Antimicrobial resistance (AMR) is a consequence of inappropriate actions, including irrational antimicrobial prescribing and use. Antimicrobial resistance remains an emergent and significant public health threat, particularly in low and middle-income countries (LMICs), including Nigeria. Optimizing antimicrobial (AM) use through functional hospital antimicrobial stewardship (AMS) programs is one of the strategies to control the spread of AMR. Literature is replete with evidence, but few studies examined the contextual factors limiting AMS functionality at the facility levels. This study explored the intrinsic contextual factors shaping AMS practice at the three-tiered levels of care. METHODS: This was a qualitative case study with a purposeful sample size of 30 participants drawn from two primary, two secondary, and two tertiary health facilities in Nigeria. Data were coded and categorized for thematic analysis. RESULTS: Emergent themes include lack of AMS programs, inadequate guidelines, lack of modern equipment and incorrect diagnosis, absence of continuous medical education, imbalance of power among professionals, and pervasive external influence of pharmaceutical marketing companies. These findings demonstrate that the AMS program is lacking or poorly implemented at the three-tiered level of care. CONCLUSION: We recommended that health facilities establish AMS programs in line with the World Health Organization's stepwise approach. These challenges, if addressed, will promote the successful performance of the AMS program, contributing to rational AM use at all levels of care. Since primary health centres constitute 85.4% of all health facilities, customizing the AMS core elements at this level will contribute to achieving the goals of universal health coverage.

RESUMO

BACKGROUND: The current pandemic of coronavirus disease (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has shown epidemiological and clinical characteristics that appear worsened in hypertensive patients. The morbidity and mortality of the disease among hypertensive patients in Africa have yet to be well described. METHODS: In this retrospective cohort study all confirmed COVID-19 adult patients (≥18 years of age) in Lagos between February 27 to July 62,020 were included. Demographic, clinical and outcome data were extracted from electronic medical records of patients admitted at the COVID-19 isolation centers in Lagos. Outcomes included dying, being discharged after recovery or being evacuated/transferred. Descriptive statistics considered proportions, means and medians. The Chi-square and Fisher's exact tests were used in determining associations between variables. Kaplan-Meier survival analysis and Cox regression were performed to quantify the risk of worse outcomes among hypertensives with COVID-19 and adjust for confounders. P-value ≤0.05 was considered statistically significant. RESULTS: A total of 2075 adults with COVID-19 were included in this study. The prevalence of hypertension, the most common comorbidity, was 17.8% followed by diabetes (7.2%) and asthma (2.0%). Overall mortality was 4.2% while mortality among the hypertensives was 13.7%. Severe symptoms and mortality were significantly higher among the hypertensives and survival rates were significantly lowered by the presence of additional comorbidity to 50% from 91% for those with hypertension alone and from 98% for all other patients (P < 0.001). After adjustment for confounders (age and sex), severe COVID-19and death were higher for hypertensives {severe/critical illness: HR = 2.41, P = 0.001, 95%CI = 1.4-4.0, death: HR = 2.30, P = 0.001, 95%CI = 1.2-4.6, for those with hypertension only} {severe/critical illness: HR = 3.76, P = 0.001, 95%CI = 2.1-6.4, death: crude HR = 6.63, P = 0.001, 95%CI = 3.4-1.6, for those with additional comorbidities}. Hypertension posed an increased risk of severe morbidity (approx. 4-fold) and death (approx. 7-fold) from COVID-19 in the presence of multiple comorbidities. CONCLUSION: The potential morbidity and mortality risks of hypertension especially with other comorbidities in COVID-19 could help direct efforts towards prevention and prognostication. This provides the rationale for improving preventive caution for people with hypertension and other comorbidities and prioritizing them for future antiviral interventions.

RESUMO

INTRODUCTION: Lagos state remains the epicentre of COVID-19 in Nigeria. We describe the symptoms and signs of the first 2,184 PCR-confirmed COVID-19 patients admitted at COVID-19 treatment centers in Lagos State. We also assessed the relationship between patients' presenting symptoms, sociodemographic and clinical characteristics and COVID-19 deaths.. METHODS: Medical records of PCR-confirmed COVID-19 patients were extracted and analyzed for their symptoms, symptom severity, presence of comorbidities and outcome. RESULTS: The ages of the patients ranged from 4 days to 98 years with a mean of 43.0(16.0) years. Of the patients who presented with symptoms, cough (19.3%) was the most common presenting symptom. This was followed by fever (13.7%) and difficulty in breathing, (10.9%). The most significant clinical predictor of death was the severity of symptoms and signs at presentation. Difficulty in breathing was the most significant symptom predictor of COVID-19 death (OR:19.26 95% CI 10.95-33.88). The case fatality rate was 4.3%. CONCLUSION: Primary care physicians and COVID-19 frontline workers should maintain a high index of suspicion and prioritize the care of patients presenting with these symptoms. Community members should be educated on such predictors and ensure that patients with these symptoms seek care early to reduce the risk of deaths associated with COVID-19.

RESUMO

Background: The study was conducted in three major leprosy referral hospitals in Northern Nigeria, which are NKST Rehabilitation Hospital, Benue State, Yadakunya Leprosy Hospital, Kano, and National Tuberculosis/Leprosy Training Hospital, Zaria. The main objective of the study was to investigate factors responsible for the occurrence of ulcers among leprosy patients reporting to the leprosy referral hospitals. Materials and Methods: An analytic study of case-control design was used, with patients having plantar ulcers as cases and those without as control. Semi-structured was administered to all cases and controls. Results: A total of 242 patients were studied; 124 patients (51.2%) had plantar ulcers whereas 118 (48.8%) had no ulcers (controls). A Chi-square test was used in the analysis to compare cases and controls. The study found differences between cases and controls with respect to patients release from treatment (RFT), gender, availability and utilization of footwear, age, occupation, and educational status. Footwears were provided to most patients, i.e. 60.8% late (i.e., after developing plantar ulcers); however, there was very good utilization of the footwears among those who had the footwears, 65.3%. Knowledge of self-care was higher among 64.5% of cases compared to only 28.1% of the controls. Conclusion: Ulcer still remains a major problem among leprosy patients, especially RFT (76.6%) and most cases are provided with footwear late. Self-care knowledge is higher among cases than controls.


RésuméContexte: L'étude a été menée dans trois hôpitaux majeurs de référence pour la lèpre dans le nord du Nigéria, qui sont l'hôpital de réadaptation NKST, l'État de Benue, l'hôpital de la lèpre de Yadakunya, Kano et l'hôpital national de la tuberculose et de la lèpre, Zaria. L'objectif principal de l'étude était d'étudier les facteurs responsables de l'apparition d'ulcères chez les patients atteints de lèpre signalant des hôpitaux de référence pour la lèpre. Matériaux et méthodes: une étude analytique de la conception cas-témoins a été utilisée, les patients ayant des ulcères plantaires comme cas et ceux qui n'ont pas le contrôle. Semi-structuré a été administré à tous les cas et contrôles. sRésultats: Au total, 242 patients ont été étudiés; 124 patients (51,2%) avaient des ulcères plantaires tandis que 118 (48,8%) n'avaient pas d'ulcères (témoins). Un test du Chi-carré a été utilisé dans l'analyse pour comparer les cas et les témoins. L'étude a révélé des différences entre les cas et les contrôles par rapport aux patients libérés du traitement (RFT), le sexe, la disponibilité et l'utilisation de la chaussure, l'âge, la profession et le statut scolaire. Les chaussures ont été fournies à la plupart des patients, soit 60,8% en retard (c'est-à -dire après développement d'ulcères plantaires); cependant, il y avait une très bonne utilisation des chaussures parmi ceux qui avaient les chaussures, soit 65,3%. La connaissance de l'autosoins était plus élevée chez 64,5% des cas que dans seulement 28,1% des témoins. Conclusion: L'ulcère reste un problème majeur chez les patients atteints de lèpre, en particulier les TF (76,6%) et la plupart des cas sont munis de chaussures en retard. La connaissance des soins personnels est plus élevée parmi les cas que les témoins.

RESUMO

The development of an educational concept of a training programme for infection prevention and control (IPC) was seen as a key issue to successfully address the complexity of change processes of professional IPC routines in clinical procedures. Therefore, the Nigeria Centre for Disease Control (NCDC), Nigeria, and the Robert Koch Institute (RKI), Germany established an interdisciplinary project framework, involving knowledge and competences from different disciplines and professions like health professionals, epidemiologists and educators (MAURICE project). A multi-module training programme for health care workers to improve IPC standards was developed and implemented based on the participatory approach and a systemic view for organizational change.

RESUMO

METHODS: All State TB control programmes in Nigeria were requested to submit 25-50 smear-positive Ziehl-Neelsen (ZN) stained slides for screening during 2013-2014. DNA was extracted from 929 slides for spoligotyping and drug-resistance analysis using microbead-based flow-cytometry suspension arrays. RESULTS: Spoligotyping results were obtained for 549 (59.1%) of 929 samples. Lineage 4 Cameroon sublineage (L4.6.2) represented half of the patterns, Mycobacterium africanum (L5 and L6) represented one fifth of the patterns, and all other lineages, including other L4 sublineages, represented one third of the patterns. Sublineage L4.6.2 was mostly identified in the north of the country whereas L5 was mostly observed in the south and L6 was scattered. The spatial distribution of genotypes had genetic geographic gradients. We did not obtain results enabling the detection of drug-resistance mutations. CONCLUSION/SIGNIFICANCE: We present the first national snapshot of the M. tuberculosis spoligotypes circulating in Nigeria based on ZN slides. Spoligotyping data can be obtained in a rapid and high-throughput manner with DNA extracted from ZN-stained slides, which may potentially improve our understanding of the genetic epidemiology of TB.

RESUMO

INTRODUCTION: The Ebola virus disease (EVD) outbreak in Nigeria began when an infected diplomat from Liberia arrived in Lagos, the most populous city in Africa, with subsequent transmission to another large city. METHODS: First-, second-, and third-generation contacts were traced, monitored, and classified. Symptomatic contacts were managed at Ebola treatment centers as suspected, probable, and confirmed EVD cases using standard operating procedures adapted from the World Health Organization EVD guidelines. Reverse transcription PCR tests confirmed EVD. Socio-demographic, clinical, hospitalization, and outcome data of the July-September 2014 Nigeria EVD cohort were analyzed. RESULTS: The median age of the 20 EVD cases was 33 years (interquartile range 26-62 years). More females (55%), health workers (65%), and persons <40 years old (60%) were infected than males, non-health workers, and persons aged ≥40 years. No EVD case management worker contracted the disease. Presenting symptoms were fever (85%), fatigue (70%), and diarrhea (65%). Clinical syndromes were gastroenteritis (45%), hemorrhage (30%), and encephalopathy (15%). The case-fatality rate was 40% and there was one mental health complication. The average duration from symptom onset to presentation was 3±2 days among survivors and 5±2 days for non-survivors. The mean duration from symptom onset to discharge was 15±5 days for survivors and 11±2 days for non-survivors. Mortality was higher in the older age group, males, and those presenting late. CONCLUSION: The EVD outbreak in Nigeria was characterized by the severe febrile gastroenteritis syndrome typical of the West African outbreak, better outcomes, rapid containment, and no infection among EVD care-providers. Early case detection, an effective incident management system, and prompt case management with on-site mobilization and training of local professionals were key to the outcome.

RESUMO

BACKGROUND: A major impediment to the treatment of TB is a diagnostic process that requires multiple visits. Descriptions of patient costs associated with diagnosis use different protocols and are not comparable. METHODS: We aimed to describe the direct costs incurred by adults attending TB diagnostic centres in four countries and factors associated with expenditure for diagnosis. Surveys of 2225 adults attending smear-microscopy centres in Nigeria, Nepal, Ethiopia and Yemen. Adults >18 years with cough >2 weeks were enrolled prospectively. Direct costs were quantified using structured questionnaires. Patients with costs >75(th) quartile were considered to have high expenditure (cases) and compared with patients with costs <75(th) quartile to identify factors associated with high expenditure. RESULTS: The most significant expenses were due to clinic fees and transport. Most participants attended the centres with companions. High expenditure was associated with attending with company, residing in rural areas/other towns and illiteracy. CONCLUSIONS: The costs incurred by patients are substantial and share common patterns across countries. Removing user fees, transparent charging policies and reimbursing clinic expenses would reduce the poverty-inducing effects of direct diagnostic costs. In locations with limited resources, support could be prioritised for those most at risk of high expenditure; those who are illiterate, attend the service with company and rural residents.

RESUMO

OBJECTIVE: Underdetection of TB is a major problem in sub-Saharan Africa. WHO recommends countries should have at least 1 laboratory per 100,000 population. However, this recommendation is not evidence based. METHODS: We analysed surveillance data of the Nigerian National TB Control Programme (2008-2012) to describe TB case detection rates, their geographical distribution and their association with the density of diagnostic laboratories and HIV prevalence. RESULTS: The median CDR was 17.7 (range 4.7-75.8%) in 2008, increasing to 28.6% (range 10.6-72.4%) in 2012 (P < 0.01). The CDR2012 was associated with the 2008 baseline; however, states with CDR2008 < 30% had larger increases than states with CDR2008 > 30. There were 990 laboratories in 2008 and 1453 in 2012 (46.7% increase, range by state -3% to +118). The state CDR2012 could be predicted by the laboratory density (P < 0.001), but was not associated with HIV prevalence or the proportion of smear-positive cases. CDR2012 and laboratory density were correlated among states having < and > than 1 laboratory per 100,000 population. CONCLUSION: There are large variations in laboratory density and CDR across the Nigerian states. The CDR is associated with the laboratory density. A much larger number of diagnostic centres are needed. It is likely that a laboratory density above the recommended WHO guideline would result in even higher case detection, and this ratio should be considered a minimum threshold.

RESUMO

Tuberculosis (TB) is a global public health problem, with the highest burden occurring in low-income countries. In these countries, the use of more sensitive diagnostics, such as Xpert MTB/RIF (Xpert), is still limited by costs. A cost-saving strategy to diagnose other diseases is to pool samples from various individuals and test them with single tests. The samples in positive pool samples are then retested individually to identify the patients with the disease. We assessed a pooled testing strategy to optimize the affordability of Xpert for the diagnosis of TB. Adults with presumptive TB attending hospitals or identified by canvassing of households in Abuja, Nigeria, were asked to provide sputum for individual and pooled (4 per pool) testing. The agreement of the results of testing of individual and pooled samples and costs were assessed. A total of 738 individuals submitted samples, with 115 (16%) being Mycobacterium tuberculosis positive. Valid Xpert results for individual and pooled samples were available for 718 specimens. Of these, testing of pooled samples detected 109 (96%) of 114 individual M. tuberculosis-positive samples, with the overall agreement being 99%. Xpert semiquantitative M. tuberculosis levels had a positive correlation with the smear grades, and the individual sample-positive/pooled sample-negative results were likely due to the M. tuberculosis concentration being below the detection limit. The strategy reduced cartridge costs by 31%. Savings were higher with samples from individuals recruited in the community, where the proportion of positive specimens was low. The results of testing of pooled samples had a high level of agreement with the results of testing of individual samples, and use of the pooled testing strategy reduced costs and has the potential to increase the affordability of Xpert in countries with limited resources.

RESUMO

BACKGROUND: Adverse events (AEs) of second line anti-tuberculosis drugs (SLDs) are relatively well documented. However, the actual burden has rarely been described in detail in programmatic settings. We investigated the occurrence of these events in the national cohort of multidrug-resistant tuberculosis (MDR-TB) patients in Nigeria. METHOD: This was a retrospective, observational cohort study, using pharmacovigilance data systematically collected at all MDR-TB treatment centers in Nigeria. Characteristics of AEs during the intensive phase treatment were documented, and risk factors for development of AEs were assessed. RESULTS: Four hundred and sixty patients were included in the analysis: 62% were male; median age was 33 years [Interquartile Range (IQR):28-42] and median weight was 51 kg (IQR: 45-59). Two hundred and three (44%) patients experienced AEs; four died of conditions associated with SLD AEs. Gastro-intestinal (n = 100), neurological (n = 75), ototoxic (n = 72) and psychiatric (n = 60) AEs were the most commonly reported, whereas ototoxic and psychiatric AEs were the most debilitating. Majority of AEs developed after 1-2 months of therapy, and resolved in less than a month after treatment. Some treatment centers were twice as likely to report AEs compared with others, highlighting significant inconsistencies in reporting at different treatment centers. Patients with a higher body weight had an increased risk of experiencing AEs. No differences were observed in risk of AEs between HIV-infected and uninfected patients. Similarly, age was not significantly associated with AEs. CONCLUSION: Patients in the Nigerian MDR-TB cohort experienced a wide range of AEs, some of which were disabling and fatal. Early identification and prompt management as well as standardized reporting of AEs at all levels of healthcare, including the community is urgently needed. Safer regimens for drug-resistant TB with the shortest duration are advocated.

RESUMO

BACKGROUND: Chest-x-ray is routinely used in the diagnosis of smear negative tuberculosis (TB). This study assesses the incremental cost per true positive test of a point-of-care digital chest-x-ray, in the diagnosis of pulmonary mycobacterial infections among HIV patients with presumed tuberculosis undetected by smear microscopy. METHODS: Consecutive patients with clinical suspicion of pulmonary tuberculosis were serially tested for Human immunodeficiency virus (HIV), their sputum examined for Acid Fast Bacilli then cultured in broth and solid media. Cultures characterized as tuberculous (M.tb) and non-tuberculous (NTM) mycobacteria by Hain assays were used as gold standards. A chest-x-ray was classified as: (1) consistent for TB, (2) not consistent for TB and (3) no pathology. RESULTS: Of the 1391 suspected cases enrolled, complete data were available for 952 (68%): 753/952 (79%) had negative smear tests while 150/753 (20%) had cultures positive for TB. Of those, 82/150 (55%) had chest-x-ray signs consistent with TB and 29/82 (35%) were positive for HIV. Within the co-infected, 9/29 (31%) had NTM infections. Among all suspects, the cost per positive case detected using smear microscopy test was $52.84; the overall incremental cost per positive case using chest-x-ray in smear negatives was $23.42, and in smear negative, HIV positive patients the cost was $15.77. CONCLUSION: Point-of-care chest-x-ray is a cost-effective diagnostic tool for smear negative HIV positive patients with pulmonary mycobacterial infection.

RESUMO

Objective. Data on pulmonary tuberculosis (TB) caused by Mycobacterium tuberculosis (MTB) complex in Nigeria are limited. We investigated species of MTB complex in TB cases from northern Nigeria. Methods. New TB suspects were enrolled, screened for HIV and their sputum samples were cultured after routine microscopy. Genotypes MTBC and MTBDRplus were used to characterize the MTB complex species and their resistance to isoniazid and rifampicin. Results. Of the 1,603 patients enrolled, 375 (23%) had MTB complex infection: 354 (94.4%) had Mycobacterium tuberculosis; 20 (5.3%) had Mycobacterium africanum; and one had Mycobacterium bovis (0.3%). Cases were more likely to be male (AOR = 1.87, 95% CI : 1.42-2.46; P ≤ 0.001), young (AOR = 2.03, 95% CI : 1.56-2.65; P ≤ 0.001) and have HIV (AOR = 1.43, 95% CI : 1.06-1.92; P = 0.032). In 23 patients (6.1%), the mycobacterium was resistant to at least one drug, and these cases were more likely to have HIV and prior TB treatment (AOR = 3.62, 95% CI : 1.51-8.84; P = 0.004; AOR : 4.43; 95% CI : 1.71-11.45 P = 0.002 resp.), compared to cases without any resistance. Conclusion. Mycobacterium tuberculosis remained the predominant specie in TB in this setting followed by Mycobacterium africanum while Mycobacterium bovis was rare. The association of TB drug resistance with HIV has implications for TB treatment.

RESUMO

With an annual new case detection of 4000 people, a Grade 2 disability rate of 12%, and nearly 10% child ratio among new cases, leprosy remains a disease of public health importance in Nigeria. Faced with the reality of low endemicity; a declining budgetary allocation to leprosy control; and a pervasive loss of expertise; it is necessary for Nigeria to re-organise its leprosy control services to further reduce the burden of the disease and ensure quality care to people affected by leprosy.

RESUMO

The study aims at describing the achievements and challenges of Leprosy control in Kaduna State using appropriate indicators. The study was a five year (2004-2008) retrospective review of the Leprosy records and annual reports of all the twenty three LGAs in Kaduna State. Various Leprosy indicators were calculated and presented in different graphic presentations. Focus group discussions were organised with the aim of identifying current challenges of Leprosy control in the State. There was a decline in the new Leprosy cases detected annually from 226 cases in 2004 to 140 cases in 2008. The prevalence rate ranged between 0.3-0.4 per 10,000 population within the five year period. The proportion of children among new cases dropped from 12% in 2004 to 5% in 2007 and increased to 9% in 2008. Grade 2 disability among new cases was very high (between 21%-27%) within the same period. Leprosy elimination target has been achieved in Kaduna State, but new cases with high proportion of children and WHO grade 2 disability were still been reported.
