Analysis of the influencing factors and clinical related characteristics of pulmonary tuberculosis in patients with type 2 diabetes mellitus

BACKGROUND In China,the prevalence of type 2 diabetes mellitus(T2DM)among diabetic patients is estimated to be between 90%-95%.Additionally,China is among the 22 countries burdened by a high number of tuberculosis cases,with approximately 4.5 million individuals affected by active tuberculosis.Notably,T2DM poses a significant risk factor for the development of tuberculosis,as evidenced by the increased incidence of T2DM coexisting with pulmonary tuberculosis(T2DMPTB),which has risen from 19.3%to 24.1%.It is evident that these two diseases are intricately interconnected and mutually reinforcing in nature.AIM To elucidate the clinical features of individuals diagnosed with both T2DM and tuberculosis(T2DM-PTB),as well as to investigate the potential risk factors associated with active tuberculosis in patients with T2DM.METHODS T2DM-PTB patients who visited our hospital between January 2020 and January 2023 were selected as the observation group,Simple DM patients presenting to our hospital in the same period were the control group,Controls and case groups were matched 1:2 according to the principle of the same sex,age difference(±3)years and disease duration difference(±5)years,patients were investigated for general demographic characteristics,diabetes-related characteristics,body immune status,lifestyle and behavioral habits,univariate and multivariate analysis of the data using conditional logistic regression,calculate the odds ratio(OR)values and 95%CI of OR values.RESULTS A total of 315 study subjects were included in this study,including 105 subjects in the observation group and 210 subjects in the control group.Comparison of the results of both anthropometric and biochemical measures showed that the constitution index,systolic blood pressure,diastolic blood pressure and lymphocyte count were significantly lower in the case group,while fasting blood glucose and high-density lipoprotein cholesterol levels were significantly higher than those in the control group.The results of univariate analysis showed that poor glucose control,hypoproteinemia,lymphopenia,TB contact history,high infection,smoking and alcohol consumption were positively associated with PTB in T2DM patients;married,history of hypertension,treatment of oral hypoglycemic drugs plus insulin,overweight,obesity and regular exercise were negatively associated with PTB in T2DM patients.Results of multivariate stepwise regression analysis found lymphopenia(OR=17.75,95%CI:3.40-92.74),smoking(OR=12.25,95%CI:2.53-59.37),history of TB contact(OR=6.56,95%CI:1.23-35.03)and poor glycemic control(OR=3.37,95%CI:1.11-10.25)was associated with an increased risk of developing PTB in patients with T2DM,While being overweight(OR=0.23,95%CI:0.08-0.72)and obesity(OR=0.11,95%CI:0.02-0.72)was associated with a reduced risk of developing PTB in patients with T2DM.CONCLUSION T2DM-PTB patients are prone to worse glycemic control,higher infection frequency,and a higher proportion of people smoking,drinking alcohol,and lack of exercise.Lymphopenia,smoking,history of TB exposure,poor glycemic control were independent risk factors for T2DM-PTB,and overweight and obesity were associated with reduced risk of concurrent PTB in patients with T2DM.

Treatment of primary nasal tuberculosis with anti-tumor necrosis factor immunotherapy:A case report

BACKGROUND Primary nasal tuberculosis(TB)is a rare form of extrapulmonary TB,particularly in patients receiving anti-tumor necrosis factor(TNF)immunotherapy.As a result,its diagnosis remains challenging.CASE SUMMARY A 58-year-old male patient presented to the ear,nose,and throat department with right-sided nasal obstruction and bloody discharge for 1 month.He was diagnosed with psoriatic arthritis and received anti-TNF immunotherapy for 3 years prior to presentation.Biopsy findings revealed chronic granulomatous inammation and a few acid-fast bacilli,suggestive of primary nasal TB.He was referred to our TB management department for treatment with oral anti-TB agents.After 9 months,the nasal lesions had disappeared.No recurrence was noted during follow-up.CONCLUSION The diagnosis of primary nasal TB should be considered in patients receiving TNF antagonists who exhibit thickening and crusting of the nasal septum mucosa or inferior turbinate,particularly when pathological findings suggest granulomatous inflammation.

Factors of Adherence to Concurrent Tuberculosis Treatment and Antiretroviral Therapy among HIV-TB Co-Infected Individuals in the East Region, Cameroon in the COVID-19 Era: A Retrospective Cohort Study

Context/Objectives: Tuberculosis (TB) and HIV co-infection is a serious health problem in Cameroon. The problems associated with poor adherence to treatment are on the increase worldwide. This problem can be observed in all situations where patients are required to administer their own medication, whatever the type of illness. The general objective of this study was to assess the factors affecting adherence to treatment among HIV-TB co-infected patients in health facilities in the East Region in the COVID context. Method: A retrospective cohort study before and during COVID-19 was conducted in HIV care units in 13 health districts in the East Region of Cameroon. Data were collected using a questionnaire recorded in the Kobo Collect android application, analyzed using SPSS version 25 software and plotted using Excel. Results: The pre-COVID-19 cohort compared to the during-COVID-19 cohort had a 1.90 risk of not adhering to treatment (OR: 1.90, CI {1.90 - 3.37}) and the difference was statistically significant at the 5% level (p-value = 0.029). Frequency of adherence was 65.4% (140/214). Adherence before COVID-19 was 56.9% whereas during COVID-19, it was 74.3%. Conclusion: The implementation of targeted interventions in the COVID-19 context, using evidence-based data and integrating the individual needs of HIV-TB co-infected patients, improved adherence to concurrent anti-tuberculosis treatment and antiretroviral therapy during the COVID-19 Era.

Early screening to identify and diagnose primary nasal tuberculosis in patients with tumor necrosis factor inhibitors

In this editorial,we comment on the article by Liu et al.Based on our analysis of a case report,we consider that early screening and recognition of primary nasal tuberculosis are crucial for patients undergoing treatment with tumor necrosis factor inhibitor(TNFi).While TNFi therapy increases the risk of reactivating latent tuberculosis,primary nasal tuberculosis remains rare due to the protective mechanisms of the nasal mucosa.Risk factors for primary nasal tuberculosis include minimally invasive nasal surgery,diabetes,and human immunodefi ciency virus.Patients with early symptoms such as nasal congestion,rhinorrhea,altered olfaction,epistaxis,or ulceration,and unresponsive to conventional antibiotics and antihistamines should undergo early rhinoscopy,possibly followed by repeated tissue biopsies and acid-fast bacilli culture when necessary.When diagnosis is challenging,it is essential to consider local tuberculosis epidemiology and the efficacy of diagnostic antituberculosis treatment.The preferred method for tuberculosis screening is the Interferon Gamma Release Assay,with a general recommendation for screening at 3 and 6 months after initial treatment and then every six months.However,the optimal frequency is not yet consensus-driven and may be increased in economically viable settings.

EGFR Mutation and FHIT Methylation: Inverse Relationship in Patients with Lung Adenocarcinoma and Tuberculosis

Objective:To investigate the genetic correlations between epithelial growth factor receptor(EGFR)mutation and FHIT methylation in patients diagnosed with lung adenocarcinoma(AC)and pulmonary tuberculosis(TB).Methods:The presence of EGFR mutations and the methylation status of the FHIT gene in patients presenting with AC and TB were analyzed.The correlation between TB status and the observed genetic and epigenetic variations was also examined.Results:Among the 90 patients included in the study,38 exhibited EGFR mutations(14 among those with TB and 24 among those without TB),while 29 exhibited FHIT myelination(19 among those with TB and 10 among those without TB).Furthermore,the protein expression levels of EGFR and FHIT were significantly higher in patients diagnosed solely with AC compared to those presenting with both AC and TB.A robust inverse correlation was identified between TB status and the frequency of EGFR mutation(P<0.001).Moreover,significant associations were observed between TB status and FHIT methylation(P<0.01).Conclusion:The findings suggest a correlation between TB and the prevalence of EGFR mutation and FHIT methylation in the pathogenesis of AC.

Prevalence and Risk Factors Associated with Pulmonary Tuberculosis in Diabetics in Conakry

Objectives: To determine the prevalence of pulmonary tuberculosis in diabetics, to identify risk factors associated with pulmonary tuberculosis in diabetics, and to describe the clinical features of the association of pulmonary tuberculosis and diabetes. Materials and method: This was a cohort study that took place from November 18, 2015 to January 31, 2018 at the Department of Endocrinology, Diabetology and Metabolic Diseases of the University Hospital of Donka. Results: among the 1912 diabetic patients screened for tuberculosis, 46 had bacteriologically confirmed pulmonary tuberculosis, i.e. a prevalence of 2.4% and 01 had clinically diagnosed pulmonary tuberculosis with 0.1%. A female predominance was noted with a sex ratio of 0.8. The 45 - 54 age group was the most affected with a mean age of 46 years. Body Mass Index (p = 0.001), smoking (p = 0.0101) and history of infection (p = 0.001) were significantly associated with pulmonary tuberculosis. The history of smoking (p = 0.0101), the notion of contagion (p = 0.001), the cough (p = 0.001), the fever (p = 0.001), the nocturnal sweat (p = 0.001) and the hemoptysis (p = 0.001) were the clinical characteristics significantly associated with pulmonary tuberculosis. Conclusion: The results of this study show a remarkably high prevalence of tuberculosis in diabetic patients in Guinea highlighting the need for urgent action to better understand and treat the double burden of tuberculosis and diabetes.

Tumor Necrosis Factor-Alpha (TNF)-308G/A and Interleukin 8(IL-8)-251C/T Polymorphisms in Pulmonary Tuberculosis Patients from Congo

Background: Tuberculosis (TB) is one of the world’s deadliest infectious diseases. Tumor necrosis factor-Alpha (TNF-α) and Interleukin 8 (IL-8) are involved in the pathogenesis of pulmonary TB (PTB). However, the contribution of polymorphisms of these cytokines to PTB susceptibility needed more investigation across geographic regions and ethnic groups. Purpose: The aim of this study was to investigate the association of the TNF-α-308 G/A and IL-8-251T/A polymorphisms with PTB risk in the Congolese population. Methods: This case-control study included 150 PTB patients and 160 control subjects. Blood samples were collected from all participants and were used for the TNF-α-308 G/A and IL-8-251T/A genotyping by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Odds ratios (OR) were calculated to estimate the potential polymorphism associations. A P level of Results: A significant difference was found between PTB patients and controls regarding the TNF-α-308AA genotype (P = 0.035) distribution. Moreover, this genotype was associated with risk to TB (OR = 7.19, 95% CI = 0.85 - 60.65, P = 0.035). The A allele was significantly more frequent in PTB patients than in controls, and was associated with risk to PTB (OR = 1.68, 95% CI = 1.05 - 2.68, P = 0.014). Regarding the IL-8-251T/A gene, TA and AA genotypes were significantly more frequent in PTB patients compared to controls, and were associated with increased risk to PTB (OR = 2.64, 95% CI = 0.97 - 7.18, P = 0.031 and OR = 3.0, 95% CI = 1.13 - 7.98, P = 0.014, respectively). However, the IL-8-251 A allele was not associated to PTB susceptibility (OR = 0.27, 95% CI = 0.15 - 0.44). Conclusion: TNF-α-308G/A and IL-8-251T/A polymorphisms may be associated to PTB susceptibility in the Congolese population, and the AA genotype of both cytokines could be a risk factor.

Latent tuberculosis:Risk factors,screening and treatment in liver transplantation recipients from an endemic area

BACKGROUND Patients undergoing solid organ transplantation,particularly those who live or have lived in tuberculosis(TB)endemic areas,are at a high risk of developing TB.The majority of post-transplantation TB cases are associated with reactivation of latent TB infection(LTBI).Brazil is in a single position with overlapping areas of high TB endemicity and high transplant activity.In liver transplant(LT),one should be aware of the potential hepatotoxicity associated with the treatment regimens for LTBI.AIM To evaluate the frequency of LTBI in LT patients and treatment-related issues.METHODS This was a retrospective analysis of a cohort of cirrhotic patients aged≥18 years,who underwent LT at a high-complexity teaching hospital from January 2005 to December 2012.RESULTS Overall,429 patients underwent LT during the study period.Of these,213(49.7%)underwent the tuberculin skin test(TST)during the pre-transplant period,and 35(16.4%)of them had a positive result.The treatment for LTBI was initiated after LT in 12(34.3%)of the TST-positive patients;in 3(25.0%),treatment was maintained for at least 6 mo.CONCLUSION The prevalence of LTBI was lower than expected.Initiation and completion of LTBI treatment was limited by difficulties in the management of these special patients.

Risk factors for tuberculosis after gastrectomy in gastric cancer

AIM: To examine incidence of tuberculosis(TB) in gastrectomy patients and investigate the risk factors for developing TB after gastrectomy in patients with gastric cancer.METHODS: A retrospective cohort study of gastrectomy patients with gastric cancer was performed at a university-affiliated hospital in Seoul, South Korea between January 2007 and December 2009. We reviewed patient medical records and collected data associated with the risk of TB, surgery, and gastric cancer. Standardized incidence ratios(SIRs) of TB were calculated to compare the incidence of TB in gastrectomy patients with that in the general Korean population, and risk factors for TB after gastrectomies were analyzed.RESULTS: Among the 1776 gastrectomy patients, 0.9%(16/1776) developed post-gastrectomy TB, with an incidence of 223.7 cases per 100000 patients per year. The overall incidence of TB in gastrectomy patients, adjusted by sex and age, was significantly higher thanthat in the general population(SIR = 2.22, 95%CI: 1.27-3.60). Previous TB infection [odds ratio(OR) = 7.1, P < 0.001], lower body mass index(BMI)(kg/m2; OR = 1.21, P = 0.043) and gastrectomy extent(total gastrectomy vs subtotal gastrectomy)(OR = 3.48, P = 0.017) were significant risk factors for TB after gastrectomy in a multivariate analysis.CONCLUSION: TB incidence after gastrectomy is higher than that in the general population. Previous TB infection, lower BMI, and total gastrectomy are risk factors for TB after gastrectomy in patients with gastric cancer.

Risk Factors for Hemoptysis in Pulmonary Tuberculosis Patients from Southern China: A Retrospective Study

Clinical characteristics of tuberculosis (TB) patients from southern China with pulmonary tuberculosis hemoptysis (PTH) were analyzed retrospectively in order to improve the diagnosis of TB, reduce mortality and prevent the transmission of TB. A total of 1227 cases of pulmonary TB patients hospitalized in the Third Affiliated Hospital of Sun Yat-sen University and Guangzhou Chest Hospital from January to December of 2011 were analyzed retrospectively. 1) The male/female ratio of the 1227 tuberculosis cases was 2.15:1. There were 403 cases (32.8%) of PTH with a male/ female ratio of 3.03:1. 2) The ratio of patients with PTH to those with TB was designated as Rh. The Rh in the male group (36.2%, 303 cases) was higher than that in the female group (25.6%, 100 cases, risk ratio (RR) = 1.41, P ≤ 0.001). 3) The Rh in the elderly group (≥60 years old, 20.3%, 56 cases) was lower than that in the younger patients group (20 - 39 years old, 45.4%, 189 cases, RR = 2.51, P ≤ 0.001). 4) The Rh in initial treatment group (29.6%, 296 cases) was lower than that in the retreatment group (46.9%, 107 cases, RR = 1.58, P ≤ 0.001). 5) The Rh in sputum-positive TB patients (44.5%, 297 cases) was significantly higher than that in the smear-negative TB patients (18.9%, 106 cases, RR = 2.35, P ≤ 0.001). 6) The Rh of patients with lung lesions range 0.05). 7) The Rh of patients with cavities (51.8%, 309 cases) was higher than that of patients without cavities (14.9%, 94 cases, RR = 3.48, P ≤ 0.001). Male, young, retreated, sputum-positive TB patients and those with cavitary TB were more predisposed to PTH in southern China. TB patients with such characteristics should be sensitized and accorded good care.

Risk Factors for Multidrug-Resistant Tuberculosis and Characteristics of Cases: A Case-Control Study of Patients Attending ALERT General Hospital in Addis Ababa, Ethiopia

Background:Tuberculosis remains a major public-health problem in the world, despite several efforts to improve case identification and treatment. Particularly multidrug-resistant tuberculosis is becoming a major threat to tuberculosis control programs in Ethiopia which seriously threatens the control and prevention efforts and is associated with both high death rates and treatment costs. Methods: A case-control study was conducted to assess risk factors and characteristics of MDR-TB cases at ALERT Hospital, Addis Ababa, Ethiopia, where cases were 167 MDR-TB patients, while controls were newly diagnosed and bacteriologically confirmed pulmonary TB cases of similar number, who were matched by sex and age of 5-years interval. Results: The socio-demographic characteristics of the participants indicated that majority (53.3%) were males and 46.7% females;a little over half of cases (55.1%) were in the age group 26 - 45 years, whereas 46.7% of controls were in this age group. According to the multivariable logistic regression analysis, previous history of hospital admission was the only factor that was identified as predictor which increased risk to develop MDR-TB by almost twenty times (AOR = 19.5;95% CI: 9.17 - 41.62) and P-value of <0.05. All other studied factor such as being unemployed, family size, having member of household member with TB, and history of visiting hospital in past 12 months etc., didn’t show any statistically significant association. Conclusion: The study identified previous history of hospital admission as independent predictors for the occurrence of MDR-TB, while other studied variables didn’t show any strong association. The findings added to the pool of knowledge emphasizing the need for instituting strong infection control practice at health care facilities to prevent nosocomial transmission of MDR-TB.

Systematic review and meta-analysis on the association of tuberculosis in Crohn's disease patients treated with tumor necrosis factor-α inhibitors(Anti-TNFα)

AIM To perform a meta-analysis on the risk of developing Mycobacterium tuberculosis(TB) infection in Crohn's disease(CD) patients treated with tumor necrosis factoralpha(TNFα) inhibitors.METHODS A meta-analysis of randomized, double-blind, placebocontrolled trials of TNFα inhibitors for treatment of CD in adults was conducted. Arcsine transformation of TB incidence was performed to estimate risk difference. A novel epidemiologically-based correction(EBC) enabling inclusions of studies reporting no TB infection cases in placebo and treatment groups was developed to estimate relative odds.RESULTS Twenty-three clinical trial studies were identified, including 5669 patients. Six TB infection cases were reported across 5 studies, all from patients receiving TNFα inhibitors. Eighteen studies reported no TB infection cases in placebo and TNFα inhibitor treatment arms. TB infection risk was significantly increased among patients receiving TNFα inhibitors, with a risk difference of 0.028(95%CI: 0.0011-0.055). The odds ratio was 4.85(95%CI: 1.02-22.99) with EBC and 5.85(95%CI: 1.13-30.38) without EBC.CONCLUSION The risk of TB infection is higher among CD patients receiving TNFα inhibitors. Understanding the immunopathogenesis of CD is crucial, since using TNFα inhibitors in these patients could favor mycobacterial infections, particularly Mycobacterium avium subspecies paratuberculosis, which ultimately could worsen their clinical condition.

Prevalence of Rifampicin Resistance and Associated Risk Factors among Suspected Multidrug Resistant Tuberculosis Cases in TB Centers Mogadishu-Somalia: Descriptive Study

Introduction and Background: Multidrug-resistant tuberculosis (MDR-TB) has emerged as a significant global health concern. Patients who had failed previous TB treatment, relapsed after treatment, contacted known MDRTB patients or defaulted during previous treatment, and HIV patients are considered to be suspected and at high risk for developing drug resistant TB specially MDR-TB. However, there is little data available on the prevalence and trends of MDR tuberculosis in national level but luck of it in Mogadishu is our main concern. Methodology: This was a crosssectional, descriptive study involving all suspected MDR TB patients attended at the Mogadishu three Tb centers. Results: A total of 138 cases of suspected MDRTB patients were included in the study. Of these, 70 patients (51%) had rifampicin resistant-TB. Of the 138 study participants, 94 (68.62%) were between 21 - 40 years old that indicates the dominance of productive age group (21 - 40 years). Previous Tuberculosis treatment has been noted to be a major risk factor for development of multidrug resistance tuberculosis. MDR-TB prevalence is significantly higher in male than female patients. Conclusion and Interpretation: The prevalence of Rifampicin resistance among these high risk groups was significant. The high association of previous TB treatment to MDR-TB might be explained due to inappropriate anti-tubercular regimens, sub-optimal drugs, inadequate or irregular drug supply, unsatisfactory patient or clinician compliance, lack of supervision of treatment and absence of infection control measures in healthcare facilities. As the prevalence of MDRTB is high and yet the cases remain un-isolated in the community we recommend the MOH/NTP and funding agencies to facilitate establishment of MDRTB management centers earlier in Mogadishu in order to treat the MDRTB case otherwise it might Amplify of the incidence of this Emerging Disease.

Research on variation and significance of immune cells, inflammatory factors and coagulation functions in patients with pulmonary tuberculosis

Objective:To investigate variation of T lymphocyte subsets, inflammatory factors and coagulation functional indexes at different stages for patients with pulmonary tuberculosis and significance of discussion and treatment on mechanism of pulmonary tuberculosis. Methods:48 cases of patients with pulmonary tuberculosis at progressive stage treated in our hospital were selected as the progression group, and 50 cases of patients with pulmonary tuberculosis at remission stage were selected as the remission group. Meanwhile, 48 cases of healthy population in our hospital were selected as the control group. Variations and significances of T lymphocyte subsets (CD3+, CD4+, CD8+ and CD4+/CD8+), inflammatory factors [interleukin-2 (IL-2), interleukin-10 (IL-10), interferon-γ (IFN-γ) and tumor necrosis factor-α(TNF-α)] and coagulation function [Fg (fibrinogen), TT (thrombin time), PLT (platelet) and D-D (D-dimer)] were analyzed.Results: Coagulation function (Fg, TT, PLT and D-D), T lymphocyte subsets CD8+ and inflammatory factors (IL-2, IL-10 and TNF-α) in patients with pulmonary tuberculosis in progression group were significantly higher than in healthy population of control group (P<0.05). T lymphocyte subsets (CD3+, CD4+ andCD4+/CD8+) and IFN-γ were significantly lower than in healthy population of control group (P<0.05). Coagulation function (Fg, TT, PLT and D-D), T lymphocyte subsets CD8+ and inflammatory factors (IL-2, IL-10 and TNF-α) in patients with pulmonary tuberculosis in remission group were significantly lower than in patients of progression group (P<0.05), but significantly higher than in healthy population of control group (P<0.05). T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) and IFN-γ in patients with pulmonary tuberculosis in remission group were significantly higher than in patients of progression group (P<0.05), but significantly lower than in healthy population of control group (P<0.05).Conclusions:Significant variations appeared on T lymphocyte subsets, inflammatory factors and coagulation functional indexes at different stages for patients with pulmonary tuberculosis, which had important significance on discussion and treatment of pulmonary tuberculosis mechanism.

Latent Tuberculosis Infection among Household Contacts of Pulmonary Tuberculosis Cases in Central State, Sudan: Prevalence and Associated Factors

Introduction: Tuberculosis is a major health problem in developing countries including Sudan. Screening for TB cases through Household contacts (HHCs) investigation is an appropriate strategy to interrupt transmission of TB. Objectives: To determine the prevalence tuberculosis infection and risk factors for tuberculosis infection among household contacts in Wadimadani locality, Central State, Sudan, between November 2015 and April 2016. Methods: An analytical cross-sectional study conducted. During study period, to confirm TB diagnosis, all suspect contacts were tested through sputum samples, tuberculin skin test or chest X-ray. Structured questionnaire was used to collect socio-demographic and environmental factors. Results: One hundred forty six patients of smear-positive pulmonary tuberculosis were included in the study, 657 household contacts were identified and screened. Forty three new TB cases were detected from household contacts, yielding a prevalence of 6.5% (95% confidence interval = 0.05, 0.09) of latent tuberculosis infection (LTBI). Two factors were significantly associated with LTBI among HHCs: duration of contact with a TB patient ≤ 4 months (P = 0.03) and the educational status (P = 0.02). Conclusion: Screening of HHCs of index case of TB will contribute in early detection and treatment of new cases, and considered as a forward step towards eliminating TB.

Patient and Health System Factors Associated with First Line Tuberculosis Treatment Adherence, 2009-2014

Background: The prevalence and incidence rate of tuberculosis remains high although the disease is known to be almost always curable provided the patient adheres to the treatment regimen. This study assessed the strength of association between known patient and health system factors associated with first line tuberculosis treatment adherence. Methods: A quantitative cross sectional study. Retrospective chart reviews were conducted among 570 persons who had primary tuberculosis and received first line treatment at a health facility within the Nkangala district, Mpumalanga province and who had a treatment outcome recorded between 1st January 2009 and 31st December 2014. Adherence to first line tuberculosis treatment was defined as taking ≥80% of tuberculosis prescribed drugs within a period of 6 to 8 months. Stata software (logistic regressions model) was used to analyze results and find the strength of association between known factors and treatment adherence. Results: Out of the 570 study participants, 473 were adherent and 96 were not adherent. There was a statistically significant association between age 18 years and above (OR: 1.02, P-value: 0.027), sex (lower in males OR: 0.44, P-value: 0.001) and support (OR: 3.04, P-value: 0.05) and HIV (OR: 1, P-value: 0.634) and first line TB treatment adherence. Conclusion and Recommendation: >80% adherence to first line tuberculosis outcome is possible. The support given to people with tuberculosis will further enhance adherence to first line tuberculosis treatment.

Risk Factors in the Transmission of Tuberculosis in Nairobi: A Descriptive Epidemiological Study

Background: Tuberculosis is an infectious disease with an estimated 1.45 million deaths every year. Many patients get infected as a result of ignorance of the risk factors that contribute to disease transmission. Methodology: A descriptive epidemiological study was conducted on 258 patients presenting with pulmonary tuberculosis. Patients’ sputa were collected for laboratory analysis and patients were required to respond to a structured questionnaire on risk factors for transmission. Data among stratified groups were compared using bivariate analysis. Statistical significance was considered at p Results: There were significantly more males than females associated with pulmonary tuberculosis infection (χ2 = 0.963;df = 1;p (64.3%) patients were living in single rooms with 110 (42.6%) living with more than two people with a maximum of 10 people in a single room. Only 73 (28.3%) were living alone in a single room and only 7 families (2.7%) were living in houses with five or more rooms. Alcohol consumers and smokers were 102 (39.5%) and 93 (36%) respectively. Half of the patients (137 (53.3%)) had not completed secondary education with only 16 (6.2%) having completed tertiary education. Recurrent cases were 54 (21%) while those exposed to the disease either at home or working place were 75 (29.2%). Out of 171 patients who agreed to test for HIV, 46 (26.9%) were positive. Marital status had no effect on incidence of disease. Conclusion: Emphasis should be given to creating awareness of the risk factors associated with transmission of tuberculosis in order to reduce the rate of infection.

Factors Associated with Death among Tuberculosis Patients in Dakar

Introduction-Objective: Tuberculosis (TB) is the leading cause of death from a single infectious agent worldwide. The predictors of mortality due to TB are rarely evaluated in Senegal. The aim of our study was to identify factors associated with related TB death in two treatment centers in Dakar, Senegal. Method: We conducted a prospective descriptive-analytical study dealing with TB patients followed in the Department of Infectious and Tropical Diseases at FANN Teaching Hospital and Dakar Principal Hospital and in the Department of Pulmonology at Dakar Principal Hospital from March 1st, 2019 to February 29th, 2020. Univariate and multivariate logistic regressions were performed to identify the associated factors of death. Results: Two hundred eighty-two patients in the Department of Infectious and Tropical Diseases at FANN teaching hospital (57%), in the Department of Infectious and Tropical Diseases at Dakar Principal Hospital (31%), and in the Department of Pulmonology at Dakar Principal Hospital (12%) were included in the study. The mean age was 39 ± 16 years and the male to female ratio was 2.2. Isolated pulmonary TB, isolated extrapulmonary TB, and both pulmonary and extrapulmonary TB were present in 33.3%, 30.5% and 36.2% of cases, respectively. Twenty-two patients died, corresponding to a mortality rate of 7.8%. Factors independently associated with death were age ≥ 60 years (26.2 [3.6 - 191.2]) compared to 16 - 40 years’ age group, HIV infection (7.2 [1.4 - 36.9]), neurological localization of TB (13.19 [3.2 - 54.3]), and hemoglobin level < 10 g/dl (5.5 [1.3 - 23.9]). Conclusion: Tuberculosis remains a fatal disease despite therapeutic advances. Better knowledge of associated factors of death from TB may help to reduce its mortality.

Demographic Factors Associated with Health-Related Quality of Life Among Urban and Rural Tuberculosis Patients in Kenya

Background:Tuberculosis is one of the deadliest and disabling diseases in the world today.The infection exacts its greatest toll on individuals during their most productive years.TB patients record different perceived health related qualities of life(PHRQoL)which could be attributed to certain environmental,social and physical factors.The objective of the study was to determine the demographic factors associated with the PHRQoL among urban and rural Tuberculosis patients in Kenya.Cross sectional design was adopted.The study applied the multi-stage sampling technique.Random sampling method was used to select the TB clinics that participated in the study.Simple random sampling according to probability proportionate to TB patient’s population was preferred to select the study participants.Chisquare test determined association between the various demographic factors and the PHRQoL while ANOVA tests demonstrated the overall association of demographic factors and PHRQoL.Statistical Significance was evaluated at p<0.05.Descriptive statistics summarized and described the data.The study established that demographic factors are associated with PHRQoL(p=0.008).Specifically,age,levels of education,marital status and house hold size(P<0.05).Gender and Household head were not significantly associated with the PHRQoL(p>0.05).These findings will persuade the TB management policy towards developing an intervention programs directed at the social-demographic characteristics of the TB patients for improved treatment outcomes.
