Trends in Rifampicin Resistance Among Children With Presumptive TB in the Pre-COVID and COVID-Era

Publications on COVID-19's impact on the global tuberculosis burden are from adult cohorts, pediatric data are lacking for inform decision. We compared the TB trends in southern Nigerian children in the pre-COVID-19 and COVID-19 era. This was a retrospective, cross-sectional study of early morning sputum/gastric washing or stool samples from children with presumptive TB evaluated using GeneXpert in a tertiary hospital from January 2016 to May 2022. Of the 20 589 persons screened for presumed TB in the pre-COVID-19 and the COVID-19 era, only 1104 (88.7%) of 1245 children had complete data for analysis. In the COVID era, a significantly higher number of children were presumed to have TB 755 (68.4%), P < .001. The overall incidence of MTB detected by Xpert MTB/RIF during the study period was 6.4% (71/1104). The incidence of MTB in the pre-COVID-19 era was 24/349 (6.9%), which was slightly higher than the COVID-19 era (47/755; 6.2%), P > .05). The annual trends of MTB detected peaked in 2019 [18/115; 15.7%] in the pre-COVID-19 era, then plummeted to 12/228 (5.3%) in 2020 in the COVID-19 era, and reached its all-time low of 6/160 (3.8%) in the first half of 2022, (P < .001). The overall incidence of Rifampicin-resistant TB (RR-TB) was 2.8% among the MTB detected cases and all occurred in the COVID-19 era. This study found a significant decline in MTB diagnosis and in the emergence of RR-TB in the COVID-19 era. This necessitates re-prioritizing worldwide efforts to manage childhood tuberculosis, including increased testing, if the aim of eliminating tuberculosis by 2035 is to be met.

Trends in pediatric tuberculosis diagnosis utilizing xpert Mycobacterium tuberculosis/Rifampicin in a poor-resource, high-burden region: A retrospective, multicenter study

Background

The burden of tuberculosis (TB) in Nigeria remains high, and diagnosis in children, a challenge. We aimed to document yield from Xpert Mycobacterium tuberculosis/rifampicin (MTB/RIF) as a mode of diagnosis for children and the variables associated with a positive result.

Methods

This was a retrospective review of TB treatment cards of children aged 0-15 years managed from January 2017 to December 2021 across six public tertiary institutions in Nigeria. The data obtained were analyzed using the descriptive and inferential statistics. Statistical significance was set at P < 0.05.

Results

Of 1489 children commenced on TB treatment, 1463 (97.9%) had sufficient data for analysis the median age of study participants was 60 months (interquartile range [IQR]: 24, 120), and 814 (55.6%) were males. Xpert MTB/RIF test was performed in 862 (59%) participants and MTB was detected in 171 (19.8%) participants, of which 6.4% (11/171) had RIF resistance reported. The use of Xpert MTB/RIF rose from 56.5% in 2017 to 64% in 2020 but fell to 60.9% in 2021. We found that older age (> 10 years), the presence of pulmonary TB (PTB), and a negative human immunodeficiency virus (HIV) status were associated with positive Xpert MTB/RIF tests (P = 0.002, 0.001, and 0.012, respectively).

Conclusion

The utilization of Xpert MTB/RIF in children increased in the years before the COVID-19 pandemic. Factors associated with MTB detection by Xpert MTB/RIF include older age, the presence of PTB, and a negative HIV status. Clinical and radiological evaluation continues to play vital roles in the diagnosis of childhood TB in Nigeria.

Challenges of caregivers and needs of children with parents in a Nigerian prison

BACKGROUND

Separation of a parent from the family as a result of incarceration has both short-term and long-term effects on the family, even after release from prison. This study is a report of factors and challenges of the family left to adapt to the changed circumstances of separation from parent(s) who are incarcerated.

METHODS

This was a cross sectional study carried out on 89 caregivers of children whose parents are incarcerated at the Agodi prison, Ibadan who gave informed and written consent to interview their families.

RESULTS

Most caregivers had little or no formal education (69.7%) and 67.4% are into petty trading or subsistence farming. A majority of the caregivers reported the need of schooling (85.4%), provision of food (84.3%) and medical care (71.9%) as major challenges, only 25% received any form of support to meet these needs. Twenty-nine (32.6%) respondents reported receiving financial support to provide for the child's feeding. Some caregivers 21 (23.6%), obtained loans to cope with the financial needs of the children while only 3 (3.4%) received support from family or other non-governmental organisations.

CONCLUSION

The caregivers of children of prison inmates face significant challenges in meeting the needs of feeding, health and schooling. Support structures and policies to address these gaps are required.

Comparison of point-of-care glucometers and laboratory based glucose oxidase test in determining blood glucose levels

INTRODUCTION

Alterations in blood glucose levels are common and an important determinant of a patient's admission outcomes, point-of-care glucometers, which are affected by a variety of factors, are increasingly used in clinical care. In this study we compared blood glucose levels determined by two commonly used glucometers (One Touch^® and Accu-check^®) with those of a standard laboratory method and determined the effect of haematocrit on glucose readings.

METHODS

Blood glucose levels were measured with One Touch^® and Accu-Check^® glucometers and the glucose oxidase method at the same time in 295 children aged 0 to 15 years over a 6-month period. Bland-Altman and correlation analysis were used to explore biases among the three methods. For all statistical tests, a p-value of less than 0.05 was considered statistically significant.

RESULTS

Most were males (51.2%) and the median (range) age was 1 year (1 day, 12 years). There was a significant correlation between each of the glucometer methods and laboratory blood sugar, and the correlation between the two glucometers was strong and significant. This correlation remained statistically significant even after controlling for haematocrit values. There was an acceptable level of bias (3.9 mg/dL) between the One Touch^® and Accu-check^® glucometers, but each had a remarkably large bias compared with the glucose oxidase method.

CONCLUSION

The use of a tested glucometer in clinical settings can aid in rapid decision-making, but there is a need to periodically cross-check with the glucose oxidase method in the laboratory to optimise treatment outcomes for children with dysglycaemia.

Effectiveness of Faith-Based Interventions on the Rate of Discharged Against Medical Advice in Tertiary Newborn Units in Nigeria: A Protocol for an Open Label Randomized Control Trial

BACKGROUND

Discharged against medical advice (DAMA) is a risk factor that often leads to adverse outcomes and hospital readmissions in neonatal units. A few studies have shown that spiritual/faith-based interventions (FBIs) tend to have a lower incidence of DAMA compared with public hospitals. Perhaps, a holistic approach to patient care that addresses the spiritual needs, the soul and the body component of a being in this setting may account for the observed lower incidence of DAMA. Limited randomized control trials (RCTs) exist on FBIs with regard to DAMA in the published literature. This study seeks to compare the effectiveness of FBI, social support, religiosity, and types of FBI on neonatal DAMA against standard of care in tertiary hospitals in Nigeria.

METHODS

This RCT will be conducted in two public tertiary teaching hospitals in two of the six geopolitical zones in Nigeria. The sociodemographic and clinical details of all patients admitted to the neonatal wards during the study period will be documented. Study participants will be selected through a multistage sampling technique. Subjects will be randomized and allocated to treatment and control arms having the established baseline measure of social support and religiosity. Ethical approval was obtained from the State Research Ethics Review Committee. A written informed consent will be obtained from the parents/caregivers prior to patient enrolment. The study will be conducted in line with the Declaration of Hesinki 2000. Appropriate statistical tools will be used for data collection and analysis.

DISCUSSION

The outcome of this analysis will give insights into the effectiveness of FBI on DAMA. It will also predict the effect of the mediators of parents/caregivers' religiosity, spirituality, forms of FBI, the religious sect of parents/caregivers, and social support on the rate of DAMA on neonatal admission in tertiary hospitals in Nigeria. This could help Public Health Institutions and Governments make decisions about the determinants of neonatal DAMA and how to mitigate such outcomes. It is hoped that the evidence from this study may guide policy formulation and guidelines on enhancing hospital retention of sick neonates until they are fit for discharge.

TRIAL REGISTRATION

This study was registered at the Pan Africa Clinical Trial Registry (PACTR202102670906630).

Co-existing sickle cell anaemia and inflammatory bowel disease: case report and review of the literature

Sickle cell anaemia (SCA) is a chronic haemolytic anaemia associated with vaso-occlusive painful crises which may affect several systems including the gastro-intestinal system, resulting in abdominal pain. The concurrence of inflammatory bowel disease and haemoglobinopathy is rare. No previously reported concurrent cases of both SCA and ulcerative colitis (UC) in sub-Saharan Africa were found in the literature. A 16-year-old girl with concurrent SCA and UC is presented. She was admitted to University College Hospital, Ibadan with a 1-year history of recurrent peri-umbilical pain and bloody stools. These symptoms were mainly attributed to SCA at the referring hospital, and she was managed for chronic tropical diarrhoea without a remarkable clinical response. This case illustrates the concurrent presentation of SCA and ulcerative colitis which led to the missed and delayed diagnosis of ulcerative colitis.

HCV co-infection is associated with metabolic abnormalities among HAART naive HIV-infected persons

OBJECTIVES

To determine the metabolic abnormalities among Hepatitis C Virus (HCV) co infected HAART naïve HIV infected persons within the adult ARV clinic of the University College Hospital/University of Ibadan, Ibadan, Nigeria Methods: This was a retrospective study involving the review of clinical records of newly recruited HIV-infected persons in the adult antiretroviral (ARV) clinic over a 12 month period (January - December 2006). Baseline results for fasting plasma glucose (FPG) and fasting lipid profile were retrieved.

RESULTS

Out of the 1,260 HIV infected persons seen during the study period, HCV co-infection was found in 75 (6%) persons. The median values for total cholesterol, LDL-cholesterol and HDL-cholesterol were lower in the HCV co-infected persons. HIV-HCV co-infection was associated with a 0.31 mmol/L depression in Total Cholesterol (TC). The median FPG concentration was significantly higher in HIV-HCV co-infected than HIV only infected persons (5.33mmol/L vs. 5.00mmol/L, p = 0.047). However, regression analysis showed there was no relationship between the HIV-HCV co infected state and fasting glucose levels.

CONCLUSION

HIV-HCV co-infection may be associated with a predictable decline in plasma cholesterol, but FPG may not be sufficient to demonstrate insulin resistance in these persons.

Dyslipidemia in ART-Naive HIV-Infected Persons in Nigeria--Implications for Care

AIMS

This study aimed to describe the prevalence and pattern of lipid abnormalities among antiretroviral therapy (ART)-naive HIV patients, understand if there is any relationship to virologic and immunologic status, and discuss the implications for care.

METHODS

This was a cross-sectional study in which baseline demographic, clinical, and laboratory data of all ART-naive HIV-infected individuals recruited into the adult ARV clinic, University College Hospital, Ibadan, between January and December 2006, were analyzed.

RESULTS

In total, 1316 ART-naive HIV-infected persons were recruited in the period. Females subjects and participants aged ≦35 years accounted for 67.1% and 57.7% of all participants, respectively. At least 1 abnormal lipid fraction was seen in 73.3% of participants. It was observed that in 11.5% participants the total cholesterol (TC) was ≧5.2 mmol/L, in 2.7% the low-density lipoprotein cholesterol (LDL)-C was >4.1 mmol/L in 56.5% the high-density lipoprotein cholesterol (HDL)-C was <1.0 mmol/L, and in 27.6% the triglyceride (TG) was >1.7 mmol/L. The TC, LDL-C, and HDL-C were all significantly positively correlated with CD4 counts and negatively correlated with viral load. On the contrary, the TG levels were negatively correlated with CD4 counts and positively correlated with viral load. Multivariate linear analysis showed a significant relationship between all the lipid parameters and viral load. CD4 counts were only significantly associated with TC.

CONCLUSIONS

A significant burden of dyslipidemia exists among ART-naive HIV-infected persons. Low HDL-C was the most frequently observed abnormality. The abnormalities related more with viral load levels than with CD4 counts. Dyslipidemia screening should be done in ART-naive HIV-infected persons. Simple healthy lifestyle changes should be emphasized, with other care given to those with the disorder.
