In Nigeria, little is known about the development of new or additional physical disability during leprosy treatment. The objective of this study was to determine the prevalence and evaluate factors ...associated with worsening of physical disability during leprosy treatment in Nigeria.
This was a retrospective cohort study conducted among leprosy patients treated in six referral facilities in six States in Nigeria between January 2011 and December 2015. Multivariable logistic regression analysis was used to identify predictors of worsening disability after treatment.
Of 984 leprosy patients who completed treatment, the mean age of the patients was 39.8±17.6 years and 57.4% (565/984) of them were male. Also, 51.6% (508/984) of the patients had either grade 1 or 2 disability at diagnosis, but this declined to 30.8% (303/984) following treatment (p<0.001). Overall, 4.7% (46/984) of the cases developed new or additional disability (or worsening disability) during treatment. The cases with the greatest odds for developing worsening physical disability were patients from the southwest (adjusted odds ratio aOR 15.9; 95% CI 3.8-67.4) and southeast zones (aOR 4.7; 95% CI 1.1-19.2), and patients who had a leprosy reaction requiring additional corticosteroid therapy (aOR 11.7; 95% CI 4.4-31.2).
Sustained capacity building for health professionals on better monitoring and management of leprosy and its complications is strongly recommended in Nigeria.
Implementation studies are recommended to assess the feasibility and effectiveness of programmes. In Nigeria, little is known about the burden of diabetes mellitus (DM) among tuberculosis (TB) ...patients. The objective of this study was to determine screening efficacy, prevalence of DM and determinants of DM among TB patients. We report on a multi-centre implementation study carried-out in 13 health facilities in six States of Southern Nigeria. All newly diagnosed TB patients registered from March to October 2015 were screened for DM using current World Health Organisation guidelines. Overall, 2094 TB patients were evaluated, 196 (9.4%) were found to have DM. The prevalence of newly diagnosed DM was 5.5% (115/2094). DM prevalence varied according to age group; occurring in 2.2% of patients aged ≤ 25 years and 16.9% in patients aged (56-65) years. The additional yield of DM was 59% while the number needed to screen to detect a new case of DM was 18. Factors associated with DM were; age >40 years (aOR2.8, CI 2.1-3.9), rural residence (aOR2.3, 1.6-3.2), private health facility care (aOR2.0, 1.4-2.7), and having an occupation that engages in vigorous activity (aOR0.6, 0.4-0.9). The burden of DM among TB patients is high. Prioritization of DM screening for TB patients is indicated.
Abstract
Background
Poor knowledge of health care workers may be responsible for the under-diagnosis and low notification of Buruli ulcer (BU) in high-burden settings. This study assessed health care ...workers’ knowledge, attitude and risk perception of BU in Southern Nigeria.
Methods
We conducted a cross-sectional survey among 186 health care workers recruited from 58 health facilities in four states of Southern Nigeria. A semi-structured interviewer-administered questionnaire was administered to all participants.
Results
The overall mean knowledge score was 8.8±2.7 (maximum 15). Only 29.0% (54/186) of the respondents had a good knowledge of BU. The mean (SD) attitude score was 4.5±1.2 (maximum 6). Also, 61.3% (114/) of the respondents had a good attitude towards BU. The overall mean (SD) risk perception score was 2.6±1.3 (maximum 5). Only 26.3% (49/) of the respondents had a good risk perception of BU disease. Previous training was an independent predictor of good knowledge (aOR 4.6), good attitude (aOR 3.8) and good risk perception (aOR 2.9) to BU.
Conclusions
Health care workers in endemic settings of Nigeria have poor knowledge of and poor risk perception of BU disease. Training of health care workers is recommended to address the identified gaps to ensure earlier diagnosis and referral to specialist centres.
Mycolactones, secreted by Mycobacterium ulcerans, were previously believed to prevent super infection in Buruli ulcer lesions. However, little is known about secondary bacterial infections in these ...lesions. This study evaluated contaminating bacterial flora and their antibiotic susceptibility patterns in cases of previously untreated Buruli ulcer disease from three states in Southern Nigeria.
A prospective analysis was conducted between January and June of 2015 using wound swabs from eligible patients with Buruli ulcer disease, confirmed by quantitative-polymerase chain reaction, with active ulcers. Microbiological analyses including isolation of bacteria, species identification of isolates, and drug susceptibility tests were performed.
Of 51 patients, 27 (52.9%) were female. One or more bacterial species of clinical importance was isolated from each patient. A total of 17 different microbial species were isolated; 76.4% were Gram-negative and 23.6% were Gram-positive isolates. The most common bacterial species detected was Staphylococcus aureus (24%), followed by Aeromonas hydrophila (13%), Pseudomonas aeruginosa (13%), and Klebsiella pneumoniae (11%). Drug susceptibility tests showed a particularly high frequency of resistance to commonly used antimicrobials in Nigeria for Staphylococcus aureus.
Super bacterial infections occur in Buruli ulcer lesions in Nigeria, and these infections are associated with high rates of resistance to commonly used antibiotics in the country.
Poor knowledge can influence timely care-seeking among persons with Buruli ulcer disease (BUD).
To assess community knowledge, attitude and stigma towards persons with BUD in endemic settings of ...Southern Nigeria.
This was a cross-sectional survey conducted among adult community members in four States of Southern Nigeria. A semi-structured interviewer-administered questionnaire was administered to all participants.
Of 491 adults who completed the survey, 315 (64.2%) belonged to the ≤40 years age group, 257 (52.3%) were males and 415 (84.5%) had some formal education. The overall mean (SD) knowledge score was 5.5±2.3 (maximum 10). Only 172 (35.0%) of the participants had a good knowledge of BUD. A total of 327 (66.6%) considered BUD as a very serious illness. Also, there was a high-level of stigma against BUD patients; 372 (75.8%) of the participants felt compassion for and desire to help them, 77 (15.7%) felt compassion but tended to stay away from them, and 53 (10.8%) feared them because they may infect them with the disease. Having a formal education and ethnicity were independent predictors of good knowledge of BUD.
There is poor community knowledge of BUD in endemic settings of Southern Nigeria which influenced the attitude and perceptions of community members towards persons with BUD.
Background
Delayed diagnosis of Buruli ulcer can worsen clinical presentation of the disease, prolong duration of management, and impose avoidable additional costs on patients and health providers. ...We investigated the profile, delays in diagnosis, duration of hospitalisation, and associated factors among patients with Buruli ulcer in Nigeria.
Methods
This was a prospective cohort study of patients with Buruli ulcer who were identified from a community-based survey. Data on the patients’ clinical profile, delays in diagnosis and duration of hospitalisation were prospectively collected.
Results
Of 145 patients notified, 125 (86.2%) were confirmed by one or more laboratory tests (81.4% by PCR). The median age of the patients was 20 years, 88 (60.7%) were >15years old and 85 (58.6%) were females. In addition, 137 (94.5%) were new cases, 119 (82.1%) presented with ulcers and 110 (75.9%) had lower limb lesions. The mean time delay to diagnosis was 50.6 (±101.9) weeks. The mean duration of hospitalisation was 108 (±60) days. Determinants of time delay to diagnosis were higher disease category (p=0.001) and laboratory confirmation of disease (p=0.02). Determinants of longer hospitalisation were; multiple lesions (p=0.035), and having functional limitation at diagnosis and undertaking surgery (p=0.003).
Conclusions
Patients with Buruli ulcer have very long time delays to diagnosis and long hospitalisation during treatment. This calls for early case-finding and improved access to Buruli ulcer services in Nigeria.
The economic burden of Buruli ulcer for patients has not been well-documented. This study assessed the costs of Buruli ulcer care to patients from the onset of illness to diagnosis and to the end of ...treatment.
This was a cross-sectional cost of illness study conducted among patients with Buruli ulcer in four States in Nigeria between July and September 2015. A structured questionnaire was used to collect data on the patients' characteristics, household income and out-of-pocket costs of care.
Of 92 patients surveyed, 54 (59%) were older than 15years, 49 (53%) were males, and 86 (93%) resided in a rural area. The median (IQR) direct medical and non-medical cost per patient was US$124 (50-282) and US$3 (3-6); corresponding to 149% and 4% of the patients' median monthly household income, respectively. The overall direct costs per patient was US$135 (58-327), which corresponded to 162% of median monthly household income, with pre-diagnosis costs accounting for 94.8% of the total costs. The direct costs of Buruli ulcer care were catastrophic for 50% of all patients/households - the rates of catastrophic costs for Buruli ulcer care was 66% and 19% for patients belonging to the lowest and highest income quartiles, respectively.
Direct costs of Buruli ulcer diagnosis and treatment are catastrophic to a substantial proportion of patients and their families.
