Not Only COVID-19: Prevalence and Management of Latent Mycobacterium Tuberculosis Infection in Three Penitentiary Facilities in Southern Italy

Prior COVID-19 infection among newly diagnosed tuberculosis patients in a tertiary care center in Tehran: A case-control study

OBJECTIVE

To assess the risk of developing pulmonary tuberculosis (TB) in accordance with prior history of COVID-19 infection.

BACKGROUND

Since the advent of the COVID-19 pandemic much discussion has been had on the possible role it might play on global efforts to combat TB; most, focusing on the pandemic's impact on health care systems' capabilities to manage TB cases. Mechanisms have also been proposed by which the COVID-19 infection may directly affect individuals' chance of developing TB infection. Cases have been reported with a history of COVID-19 infection preceding a diagnosis of TB, evidencing its possible role as a risk factor for the disease.

METHODS

A case-control study was conducted enrolling patients diagnosed with pulmonary TB in the absence of major risk factors previous history of TB, (HIV) human immunodeficiency virus infection), end-stage renal disease, organ transplants, and use of immunosuppressive agents) for developing TB. Each patient was age and sex matched with one healthy control. Data regarding prior COVID-19 infection, diabetes, and smoking status as well as the use of corticosteroids and Tocilizumab for the treatment of COVID-19 infection was obtained. Bivariate analysis was conducted and variables with a likely association with TB status were entered in a multivariate model.

RESULTS

Bivariate analysis demonstrated a significant relationship between prior COVID-19 infection and TB (95% confidence interval = 1.1-22.8, odds ratio [OR] = 5). Among other variables the severity of COVID-19 infection was found to have a likely association with TB status (p = .125). In a multivariate model, prior COVID-19 infection per se, was not found to be significantly associated with TB (p = .12, OR = 4.5).

CONCLUSIONS

There seems to be an association between prior history of COVID-19 and a future diagnosis of TB partially linked to the severity of disease. The findings of the current study may serve as a basis for further studies to determine the need for and efficacy of measures to follow-up COVID-19 patients at an increased risk for developing TB.

Butane-related deaths in post-mortem investigations: A systematic review

Volatile substance abuse is widespread among adolescents due to its easy availability and methods of consumption. Inhalant abuse represents a current problematic issue, causing significant morbidity and mortality due to direct toxicity on several target organs and displacement of gas which results in a lack of oxygen. This review aims to evaluate post-mortem and toxicological investigations in cases of suspected butane intoxication. We performed comprehensive research using the Preferred Reporting Items for Systematic Review (PRISMA) standards. Forty scientific papers fulfilled the inclusion criteria. A total of 58 cases of butane-related deaths were found. Among these, we found 11 cases of suicide (18%), 1 case of homicide (2%), 44 cases of accidental poisoning (76%), and 2 cases of work-related deaths (4%). Autopsy and post-mortem examinations were performed in 54 cases, whereas toxicological analyses were presented in 56 cases. In autopsy, pulmonary edema (51%) and poli-visceral congestion (59%) were the most common findings. When death by butane inhalation is hypothesized, autopsy and histological findings may be nonspecific, therefore toxicological investigations assume a crucial role along with attention to the methods used to collect biological samples.

Latent Tuberculosis Infection Diagnosis Using QuantiFERON-TB Gold Plus Kit Among Correctional Workers: A Cross-Sectional Study in Francisco Beltrão-PR, Brazil

Correctional workers form a high-priority group for tuberculosis control measures because of their high exposure and risk. This cross-sectional study conducted in April and May 2022 included 71 criminal police officers from the State Penitentiary of Francisco Beltrão-PR, Brazil. Their sociodemographic and laboratory data were collected. Latent tuberculosis infection (LTBI) was assessed using a QuantiFERON-TB Gold Plus in-tube test kit. Binary logistic regression was applied to calculate the odds ratios (ORs) and 95% confidence intervals (CI) of the LTBI predictors. The prevalence of LTBI was 22.6% (95% CI, 12.8-32.2%). Factors associated with LTBI were age > 43 years (OR, 0.18; 95% CI, 0.04-0.70; p < 0.014) and the use of medications (OR, 5.13; 95% CI, 1.40-18.87; p < 0.014). The prevalence was close to that estimated worldwide for LTBI in correctional workers, reinforcing the need for occupational health control measures consisting of regular screening and treatment of positive cases of latent infection among correctional workers to reduce the risk of illness and spread of infection in the penitentiary system and community.

Tuberculosis in Prisons: Importance of Considering the Clustering in the Analysis of Cross-Sectional Studies

The level of clustering and the adjustment by cluster-robust standard errors have yet to be widely considered and reported in cross-sectional studies of tuberculosis (TB) in prisons. In two cross-sectional studies of people deprived of liberty (PDL) in Medellin, we evaluated the impact of adjustment versus failure to adjust by clustering on prevalence ratio (PR) and 95% confidence interval (CI). We used log-binomial regression, Poisson regression, generalized estimating equations (GEE), and mixed-effects regression models. We used cluster-robust standard errors and bias-corrected standard errors. The odds ratio (OR) was 20% higher than the PR when the TB prevalence was >10% in at least one of the exposure factors. When there are three levels of clusters (city, prison, and courtyard), the cluster that had the strongest effect was the courtyard, and the 95% CI estimated with GEE and mixed-effect models were narrower than those estimated with Poisson and binomial models. Exposure factors lost their significance when we used bias-corrected standard errors due to the smaller number of clusters. Tuberculosis transmission dynamics in prisons dictate a strong cluster effect that needs to be considered and adjusted for. The omission of cluster structure and bias-corrected by the small number of clusters can lead to wrong inferences.

Biological risk in Italian prisons: data analysis from the second to the fourth wave of COVID-19 pandemic

BACKGROUND

The management of COVID-19 in Italian prisons triggered considerable concern at the beginning of the pandemic due to numerous riots which resulted in inmate deaths, damages and prison breaks. The aim of this study is to shed some light, through analysis of the infection and relevant disease parameters, on the period spanning from the second to the fourth wave of the outbreak in Italy's prisons.

METHODS

Reproductive number (Rt) and Hospitalisation were calculated through a Eulerian approach applied to differential equations derived from compartmental models. Comparison between trends was performed through paired t-test and linear regression analyses.

RESULTS

The infection trends (prevalence and Rt) show a high correlation between the prison population and the external community. Both the indices appear to be lagging 1 week in prison. The prisoners' Rt values are not statistically different from those of the general population. The hospitalisation trend of inmates strongly correlates with the external population's, with a delay of 2 weeks. The magnitude of hospitalisations in prison is less than in the external community for the period analysed.

CONCLUSIONS

The comparison with the external community revealed that in prison the infection prevalence was greater, although Rt values showed no significant difference, and the hospitalisation rate was lower. These results suggest that the consistent monitoring of inmates results in a higher infection prevalence while a wide vaccination campaign leads to a lower hospitalisation rate. All three indices demonstrate a lag of 1 or 2 weeks in prison. This delay could represent a useful time-window to strengthen planned countermeasures.

Treatment of latent tuberculosis infection in incarcerated people: a systematic review

BACKGROUND

The estimated number of people deprived of liberty is increasing, with 11.55 million incarcerated globally in 2021. Transmission of Mycobacterium tuberculosis (MTB) strains is facilitated in over-crowded, poorly ventilated settings such as jails and penitentiaries. Moreover, inmates may show individual risk factors for the development of tuberculosis (TB) disease. Treatment regimens for latent tuberculosis infection (LTBI) may require up to 9 months of drug exposure and are characterized by adverse events (AEs) and low completion rates.

OBJECTIVES

to describe current scientific evidence on feasibility, acceptability and completion rate of LTBI treatment in prison/correctional institutes.

DATA SOURCES

Articles were retrieved from MEDLINE/PubMed, no time restriction was applied.

STUDY ELIGIBILITY CRITERIA

Human retrospective and prospective studies published on LTBI treatment in incarcerated populations were included.

ASSESSMENT OF RISK OF BIAS

Bias assessment plots and Egger weighted regression test were used to determine the risk of bias.

METHODS OF DATA SYNTHESIS

Absolute and relative frequencies were assessed for qualitative data. Pooled proportion of included study groups and 95% confidence interval estimates, weighted for sample sizes, were illustrated in forest plots. I² indicator association were used for true variability and overall variation. Fixed and random-effects models were chosen depending on the estimated between-study heterogeneity.

RESULTS

Of11 selected studies only 1 was conducted in a high TB incidence country. Overall, completion rates ranged from 26% to 100% across the included studies. Reason for discontinuation of treatment were transfer to other facilities, release, or loss to follow-up (LTFU) (range 0-74%), incidence of AEs (range 0-18%), and refusal or withdrawal from treatment (range 0-16%).

CONCLUSIONS

Implementation of short-course regimens in prisons should be considered given the low incidence of AEs observed; however, inmates consistently refused to complete LTBI treatment, thus underlining the need for improvement in retention in care.

Malpractice Claims and Ethical Issues in Prison Health Care Related to Consent and Confidentiality

Respecting the consent and confidentiality of a patient is an underlying element in establishing the patient’s trust in the physician and, implicitly, obtaining the patient’s compliance. In particular, cases of inmate patients require increased attention in order to fulfill this goal against a background of institutional interferences, which, in certain situations, may endanger the autonomy of the physician and their respect for the inmate’s dignity. The purpose of this article is to depict the characteristics of consent and confidentiality in a prison environment, in special cases, such as hunger strikes, violent acts, HIV testing, COVID-19 measures, and drug use, bringing into focus the physician and the inmate in the context of the particular situation where the target is disciplining someone in order for them to conform to social and juridical norms. Respecting the dignity of the inmate patient requires an adequate approach of informed consent and confidentiality, depending on each case, considering the potential unspoken aspects of the inmate’s account, which can be key elements in obtaining their compliance and avoiding malpractice claims.
