Drug-induced peripheral neuropathy and neurotoxicity are well-known adverse effects of treatment regimens that cause significant morbidity. Pyridoxine is often added to treatment regimens for the prevention and/or treatment of these side effects. The basis and effectiveness of this practice are unclear. We conducted a systematic review to evaluate the effectiveness of pyridoxine in preventing and/or treating neuropathy and neurotoxicity associated with RR-TB treatment. We included studies with patients with RR-TB who experienced neuropathy or neurotoxicity attributed to RR-TB regimens and were given pyridoxine. Our findings showed contradicting evidence on the use of pyridoxine for preventing or treating neurotoxicity due to cycloserine in the treatment of RR-TB. Moreover, pyridoxine did not have a protective effect against neuropathy and/or neurotoxicity caused by other RR-TB regimens that do not contain isoniazid. In conclusion, we found that withdrawing or withholding medications such as linezolid, cycloserine, thioamides, fluoroquinolones, and ethambutol, implicated in causing neuropathy or neurotoxicity was more effective than using pyridoxine to stop the progression of symptoms, and in some instances, led to their reversal over time.展开更多

Extrapulmonary localizations are a reason for hospitalization in our health facilities. The objective of this study was to describe the epidemiological, clinical, paraclinical and evolutionary aspects of extra pulmonary tuberculosis (EPT) at the Abass Ndao Hospital Center. Patients and Methods: This was a descriptive cross-sectional study conducted over a period of 11 years (January 1, 2010 to December 30, 2021). All patients with extrapulmonary tuberculosis hospitalized in the department of internal medicine during the recruitment period were included. Results: Fifty-two (52) patients were collected. The year 2019 recorded the most cases 23.08% (n = 20). The mean age of the patients was 40.56 ± 18.24 years. The age group 20 - 34 years 42.31% (n = 22) was the most represented. Females were in the majority 61.54% (n = 32) with a sex ratio (M/F) was 0.63. Housewives were in the majority 40.38% (n = 21). 60.87% of the cases (n = 14) came from a health facility. 38.46% of the cases had been infected. 21.74% (n = 9) were smokers. The reasons for consultation were dominated by fever (67.44%), AEG (62.79%) and cough (41.86%). Eighteen patients (40.91%) had fever. The mean time to consultation was 77.37 ± 90.3 days with extremes of 3 and 365 days. The median was 45 days. More than half of the patients 61.90% (n = 26) had anemia. Positive retroviral serology was noted in 21.43% of cases. All patients had a CRP greater than 6. More than half of the patients 51.92% (n = 27) had multifocal tuberculosis. The peritoneum 44.23% (n = 23) was the main organ affected. The average hospital stay was 9.8 ± 4.9 days with extremes of 1 and 19 days. All patients had received the protocol in force at the national level. Death was noted in 4 patients (9.52%). Conclusion: EPT is characterized in our context by a notorious diagnostic difficulty due to the multiplicity of clinical presentations, the complexity of explorations, and the problems of differential diagnosis notably with other granulomatosis, systemic lupus and cancers. This difficulty is reflected in the low rate of diagnosis with a paraclinical argument of certainty and in the long diagnostic delays.展开更多

While tuberculosis is not naturally occurring in free-living chimpanzees, it has been extensively observed in captive primates that have been in close proximity to humans or other captive primates infected with Mycobacterium tuberculosis. This case report delves into an outbreak of extra-pulmonary tuberculosis among juvenile chimpanzees within a sanctuary, detailing the associated diagnostic challenges and treatment approaches. The five cases had close contact with a caregiver infected with tuberculosis, subsequently transmitting the infection to other in-contact chimpanzees. Prolonged treatment, employing the human protocol of quadri-therapy (rifampicin, isoniazid, pyrazinamide, and ethambutol), followed by bi-therapy (rifampicin and isoniazid), resulted in complete resolution for all five cases. These cases underscore the critical importance of maintaining high levels of biosecurity, implementing effective quarantine measures, and adhering to strict hygiene practices when working with non-human primates.展开更多

In countries where tuberculosis (TB) is endemic, coinfection of COVID-19 and TB is often encountered, which increases the risk of developing severe forms of COVID-19. Objectives: The aim of this study was to determine the prevalence of COVID-19/TB coinfection at the Epidemic treatment center (ETC) in Saint-Louis (Senegal) and to describe the epidemiological, clinical, paraclinical, and outcome profile of co-infected patients. Patients and Methods: This is a retrospective, cross-sectional, descriptive cohort study based on the records of COVID-19/ TB co-infected patients who were hospitalized at the ETC in Saint-Louis (Senegal) over an 18-month period from March 2020 to September 2021. Results: Out of a total of 454 hospitalizations, we collected records of 9 patients co-infected with COVID-19/TB, resulting in a prevalence of 2%. The study included patients with a median age of 34 years (range: 10-86 years), with a male predominance (7 cases) and a sex ratio of 3.5. The majority of patients (88.9%) had severe forms of COVID-19. Dyspnea and cough were reported in all patients (100%). Pulmonary TB was the most frequent localization, with 9 cases. The diagnosis of COVID-19 was confirmed by nasopharyngeal PCR in all patients (100%). Bacilloscopy was positive in 3 out of 5 cases. One patient tested positive for GeneXpert<sup>?</sup> MTB/RIF without rifampicin resistance. All patients were prescribed the hydroxychloroquine-azithromycin combination and anti-tuberculosis treatment. Out of the nine patients, four recovered (44.4%) and five died (55.5%). Conclusion: COVID-19/TB coinfection had a low prevalence in our cohort, but was associated with a high mortality due to the frequent occurrence of severe forms of the disease.展开更多

According to the Botswana Ministry of Health, community tuberculosis care was introduced with the main goal of reducing tuberculosis-related morbidity and mortality among communities through the expansion of direct observed therapy and community involvement to community settings. The community caregivers were to support tuberculosis patients throughout their treatment period until they were cured or had completed their treatment. Settings: Two major cities of Botswana, Francistown and Gaborone, with more than twenty-two health clinics offering tuberculosis care. Objective: To investigate community caregivers’ experiences and identify programmatic strategies to improve active TB case findings under the community TB care (CTBC) program in Botswana during 2016-2021. Methods: We adopted a descriptive qualitative research design, followed by convenience purposive sampling. We obtained consent and interviewed 40 participants who met the inclusion criteria, 16 out of 73 in Gaborone and 24 out of 38 from Francistown. Results: We interviewed 40 caregivers with a mean age of 43.4 years. Accepting the caregiving role was identified as the main experience by more than two thirds of the caregivers. While at least more than two-fifth felt obligated to care for the patient at home due to personal relations. More than half of the respondents found caregiving difficult or frustrating due to some challenges encountered during the caregiving role. Behavioral modifications were suggested under different subthemes as strategies to improve active case finding. [-rId13-]Conclusion: Acceptance was the major experience in CTBC. Intensification of known programmatic strategies was suggested by caregivers to improve tuberculosis active case finding in CTBC.展开更多

文摘Rifampicin-resistant tuberculosis (RR-TB) is a global public health problem caused by mycobacterium tuberculosis resistant to Rifampicin. Drug-induced peripheral neuropathy and neurotoxicity are well-known adverse effects of treatment regimens that cause significant morbidity. Pyridoxine is often added to treatment regimens for the prevention and/or treatment of these side effects. The basis and effectiveness of this practice are unclear. We conducted a systematic review to evaluate the effectiveness of pyridoxine in preventing and/or treating neuropathy and neurotoxicity associated with RR-TB treatment. We included studies with patients with RR-TB who experienced neuropathy or neurotoxicity attributed to RR-TB regimens and were given pyridoxine. Our findings showed contradicting evidence on the use of pyridoxine for preventing or treating neurotoxicity due to cycloserine in the treatment of RR-TB. Moreover, pyridoxine did not have a protective effect against neuropathy and/or neurotoxicity caused by other RR-TB regimens that do not contain isoniazid. In conclusion, we found that withdrawing or withholding medications such as linezolid, cycloserine, thioamides, fluoroquinolones, and ethambutol, implicated in causing neuropathy or neurotoxicity was more effective than using pyridoxine to stop the progression of symptoms, and in some instances, led to their reversal over time.
文摘Background The very high burden of rifampicin resistance tuberculosis(RR-TB)and the very low detection of RR-TB cases are a major challenge that China has been facing.This study analyzed the characteristics of RR-TB detection in China after the change of RR-TB detection strategy since 2015,aiming to provide reference and evidence for the development of more precise national drug resistance tuberculosis prevention and control policy.Methods We extracted data related to rifampicin resistance screening from the national Tuberculosis Information Management System(TBIMS)from 2015 to 2019,and used descriptive research methods to analyze the screening rate of presumptive RR-TB,the number and duration of RR-TB patients detected and drug resistance testing methods in each year.Chi-square test was used to compare the differences in component ratio or rate between years,and Kruskal Wallis test was used to compare the differences in median days for detection of RR-TB patients in each year.Results A total of 68,200 RR-TB cases were detected during 2015–2019,of which 48.1%were new cases.The number and detection rate of RR-TB cases increased year by year,from 10019 and 14.3%in 2015 to 18623 and 28.7%in 2019,respectively.Of the bacteriologically confirmed TB cases,81.9%were tested for RR in 2019,a considerable increase from 29.5%in 2015.In 2019,only 41.0%of RR-TB cases had fluoroquinolones(FQs)susceptibility testing performed,and this proportion has been declining year by year since 2016.The proportion of application of rapid molecular tools increased from 24.0%in 2015 to 67.1%in 2019,and the median days to obtain RR results was significantly shortened.In 2019,76.0%of RR-TB cases were diagnosed as presumptive RR-TB in county-level hospitals.Conclusions After China modified the RR-TB detection strategy,the screening rate of RR and the number of RR-TB cases increased significantly.The RR testing methods now predominantly utilize rapid molecular tools.However,comprehensive measures should be implemented to close the gap in the detection of RR-TB cases.It is imperative to take FQs susceptibility testing seriously and effectively strengthen the laboratory capacity of county-level hospitals.
文摘BACKGROUND Mycobacterium tuberculosis(TB)is the causative agent of TB,a chronic granulo-matous illness.This disease is prevalent in low-income countries,posing a significant global health challenge.Gastrointestinal TB is one of the three forms.The disease can mimic other intra-abdominal conditions,leading to delayed diagnosis owing to the absence of specific symptoms.While gastric outlet obs-truction(GOO)remains a frequent complication,its incidence has declined with the advent of proton pump inhibitors and Helicobacter pylori eradication therapy.Gastroduodenal TB can cause upper gastrointestinal hemorrhage,obstruction,and malignancy-like tumors.CASE SUMMARY A 23-year-old male presented with recurrent epigastric pain,distension,nausea,vomiting,and weight loss,prompting a referral to a gastroenterologist clinic.Endoscopic examination revealed distorted gastric mucosa and signs of chronic inflammation.However,treatment was interrupted,possibly owing to vomiting or comorbidities such as human immunodeficiency virus infection or diabetes.Subsequent surgical intervention revealed a dilated stomach and diffuse thickening of the duodenal wall.Resection revealed gastric wall effacement with TB.CONCLUSION Primary gastric TB is rare,frequently leading to GOO.Given its rarity,suspicions should be promptly raised when encountering relevant symptoms,often requiring surgical intervention for diagnosis and treatment.

文摘The spread of tuberculosis(TB),especially multidrug-resistant TB and extensively drug-resistant TB,has strongly motivated the research and development of new anti-TB drugs.New strategies to facilitate drug combinations,including pharmacokinetics-guided dose optimization and toxicology studies of first-and second-line anti-TB drugs have also been introduced and recommended.Liquid chromatography-mass spectrometry(LC-MS)has arguably become the gold standard in the analysis of both endo-and exo-genous compounds.This technique has been applied successfully not only for therapeutic drug monitoring(TDM)but also for pharmacometabolomics analysis.TDM improves the effectiveness of treatment,reduces adverse drug reactions,and the likelihood of drug resistance development in TB patients by determining dosage regimens that produce concentrations within the therapeutic target window.Based on TDM,the dose would be optimized individually to achieve favorable outcomes.Pharmacometabolomics is essential in generating and validating hypotheses regarding the metabolism of anti-TB drugs,aiding in the discovery of potential biomarkers for TB diagnostics,treatment monitoring,and outcome evaluation.This article highlighted the current progresses in TDM of anti-TB drugs based on LC-MS bioassay in the last two decades.Besides,we discussed the advantages and disadvantages of this technique in practical use.The pressing need for non-invasive sampling approaches and stability studies of anti-TB drugs was highlighted.Lastly,we provided perspectives on the prospects of combining LC-MS-based TDM and pharmacometabolomics with other advanced strategies(pharmacometrics,drug and vaccine developments,machine learning/artificial intelligence,among others)to encapsulate in an all-inclusive approach to improve treatment outcomes of TB patients.
文摘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.

文摘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.
文摘Introduction: Tuberculosis is an infectious disease that mainly affects the lung. Extrapulmonary localizations are a reason for hospitalization in our health facilities. The objective of this study was to describe the epidemiological, clinical, paraclinical and evolutionary aspects of extra pulmonary tuberculosis (EPT) at the Abass Ndao Hospital Center. Patients and Methods: This was a descriptive cross-sectional study conducted over a period of 11 years (January 1, 2010 to December 30, 2021). All patients with extrapulmonary tuberculosis hospitalized in the department of internal medicine during the recruitment period were included. Results: Fifty-two (52) patients were collected. The year 2019 recorded the most cases 23.08% (n = 20). The mean age of the patients was 40.56 ± 18.24 years. The age group 20 - 34 years 42.31% (n = 22) was the most represented. Females were in the majority 61.54% (n = 32) with a sex ratio (M/F) was 0.63. Housewives were in the majority 40.38% (n = 21). 60.87% of the cases (n = 14) came from a health facility. 38.46% of the cases had been infected. 21.74% (n = 9) were smokers. The reasons for consultation were dominated by fever (67.44%), AEG (62.79%) and cough (41.86%). Eighteen patients (40.91%) had fever. The mean time to consultation was 77.37 ± 90.3 days with extremes of 3 and 365 days. The median was 45 days. More than half of the patients 61.90% (n = 26) had anemia. Positive retroviral serology was noted in 21.43% of cases. All patients had a CRP greater than 6. More than half of the patients 51.92% (n = 27) had multifocal tuberculosis. The peritoneum 44.23% (n = 23) was the main organ affected. The average hospital stay was 9.8 ± 4.9 days with extremes of 1 and 19 days. All patients had received the protocol in force at the national level. Death was noted in 4 patients (9.52%). Conclusion: EPT is characterized in our context by a notorious diagnostic difficulty due to the multiplicity of clinical presentations, the complexity of explorations, and the problems of differential diagnosis notably with other granulomatosis, systemic lupus and cancers. This difficulty is reflected in the low rate of diagnosis with a paraclinical argument of certainty and in the long diagnostic delays.
文摘Primate sanctuaries across Africa play a pivotal role in the rescue and rehabilitation of confiscated and rescued wild primates, many of whom have had extensive contact with humans prior to their arrival and throughout the rehabilitation process, heightening the risk of disease transmission. While tuberculosis is not naturally occurring in free-living chimpanzees, it has been extensively observed in captive primates that have been in close proximity to humans or other captive primates infected with Mycobacterium tuberculosis. This case report delves into an outbreak of extra-pulmonary tuberculosis among juvenile chimpanzees within a sanctuary, detailing the associated diagnostic challenges and treatment approaches. The five cases had close contact with a caregiver infected with tuberculosis, subsequently transmitting the infection to other in-contact chimpanzees. Prolonged treatment, employing the human protocol of quadri-therapy (rifampicin, isoniazid, pyrazinamide, and ethambutol), followed by bi-therapy (rifampicin and isoniazid), resulted in complete resolution for all five cases. These cases underscore the critical importance of maintaining high levels of biosecurity, implementing effective quarantine measures, and adhering to strict hygiene practices when working with non-human primates.

文摘In this editorial,we comment on an article published in a recent issue of the World Journal of Clinical Cases.There is a pressing need for reliable tools for diagnosing tuberculosis(TB)of the gastrointestinal tract.Despite advancements in the diagnosis and treatment,TB remains a global health challenge.Ali et al demon-strated that TB may mimic gastrointestinal conditions,such as gastric outlet obstruction,causing a delay in the diagnosis.Furthermore,the latter complication is frequently observed during infections,including Helicobacter pylori,and rarely is related to TB,as in the presented case.In line with this,we think that laboratory tests based on interferon-gamma release assays can be a helpful tool for diagnosing latent TB paced in the gastrointestinal tract.Innovative strategies and approaches for diagnosing latent/active extra pulmonary TB are crucial for establishing the diagnosis early and enhancing treatment strategies to mitigate the global burden of TB.
文摘Latent tuberculosis infection(LTBI)has become a major source of active tuberculosis(ATB).Although the tuberculin skin test and interferon-gamma release assay can be used to diagnose LTBI,these methods can only differentiate infected individuals from healthy ones but cannot discriminate between LTBI and ATB.Thus,the diagnosis of LTBI faces many challenges,such as the lack of effective biomarkers from Mycobacterium tuberculosis(MTB)for distinguishing LTBI,the low diagnostic efficacy of biomarkers derived from the human host,and the absence of a gold standard to differentiate between LTBI and ATB.Sputum culture,as the gold standard for diagnosing tuberculosis,is time-consuming and cannot distinguish between ATB and LTBI.In this article,we review the pathogenesis of MTB and the immune mechanisms of the host in LTBI,including the innate and adaptive immune responses,multiple immune evasion mechanisms of MTB,and epigenetic regulation.Based on this knowledge,we summarize the current status and challenges in diagnosing LTBI and present the application of machine learning(ML)in LTBI diagnosis,as well as the advantages and limitations of ML in this context.Finally,we discuss the future development directions of ML applied to LTBI diagnosis.

文摘BACKGROUND Tuberculosis is a chronic infectious disease and an important public health pro-blem.Despite progress in controlling tuberculosis,the incidence of tuberculosis in China is still very high,with 895000 new cases annually.This case report des-cribes the investigation of a case of severe disseminated tuberculosis in a young adult with normal immune function,conducted to ascertain why a Mycobacterium tuberculosis(M.tuberculosis)strain caused such severe disease.CASE SUMMARY A previously healthy 28-year-old woman presented to our hospital with a 1-mo-nth history of fever and fatigue.She was diagnosed with severe disseminated pulmonary tuberculosis,spinal tuberculosis with paravertebral abscesses,and tuberculous meningitis.M.tuberculosis was isolated from bronchoal-veolar lavage fluid.She was treated with standard antituberculous therapy and underwent debridement,bone graft,and internal fixation surgery for spinal tuberculosis.She responded to therapy and regained her ability to walk following the surgery.We analysed the whole-genome sequence of the strain and designated it BLM-A21.Additional M.tuberculosis genomes were selected from the Virulence Factor Database(http://www.mgc.ac.cn/cgi-bin/VFs/genus.cgi?Genus=Mycobacterium)for comparison.An evolutionary tree of the BLM-A21 strain was built using PhyML maximum likelihood software.Further gene analysis revealed that,except for the pks1 gene,BLM-A21 had similar virulence genes to the CDC 1551 and H37Rv strains,which have lower dissemination.CONCLUSION We speculate that the pks1 virulence gene in BLM-A21 may be the key virulence gene responsible for the wide-spread dissemination of M.tuberculosis infection in this previously healthy adult with normal immune function.

文摘Gastroduodenal tuberculosis(GD-TB)is exceptionally rare.The clinical manifestations of gastrointestinal TB are diverse and non-specific,which makes diagnosis difficult,leading to delayed diagnosis and high mortality.As a peer-reviewer of World Journal of Clinical Cases,I would like to share my opinion on the article published by this journal.The patient had no family history of TB or contact with people with TB.Primary GD-TB presenting as gastric outlet obstruction and normal findings of thoracic computed tomography increased the difficulty of diagnosis and treatment in this patient.The diagnosis and treatment scheme of this typical case have reference value for the clinical treatment of GD-TB.
文摘Introduction: COVID-19 is a global public health emergency that can cause acute respiratory distress syndrome. In countries where tuberculosis (TB) is endemic, coinfection of COVID-19 and TB is often encountered, which increases the risk of developing severe forms of COVID-19. Objectives: The aim of this study was to determine the prevalence of COVID-19/TB coinfection at the Epidemic treatment center (ETC) in Saint-Louis (Senegal) and to describe the epidemiological, clinical, paraclinical, and outcome profile of co-infected patients. Patients and Methods: This is a retrospective, cross-sectional, descriptive cohort study based on the records of COVID-19/ TB co-infected patients who were hospitalized at the ETC in Saint-Louis (Senegal) over an 18-month period from March 2020 to September 2021. Results: Out of a total of 454 hospitalizations, we collected records of 9 patients co-infected with COVID-19/TB, resulting in a prevalence of 2%. The study included patients with a median age of 34 years (range: 10-86 years), with a male predominance (7 cases) and a sex ratio of 3.5. The majority of patients (88.9%) had severe forms of COVID-19. Dyspnea and cough were reported in all patients (100%). Pulmonary TB was the most frequent localization, with 9 cases. The diagnosis of COVID-19 was confirmed by nasopharyngeal PCR in all patients (100%). Bacilloscopy was positive in 3 out of 5 cases. One patient tested positive for GeneXpert<sup>?</sup> MTB/RIF without rifampicin resistance. All patients were prescribed the hydroxychloroquine-azithromycin combination and anti-tuberculosis treatment. Out of the nine patients, four recovered (44.4%) and five died (55.5%). Conclusion: COVID-19/TB coinfection had a low prevalence in our cohort, but was associated with a high mortality due to the frequent occurrence of severe forms of the disease.
文摘In this editorial,we comment on the article by Ali et al published in the recent issue of the World Journal of Clinical Cases.This case report shed light on a particularly rare manifestation of this disease-primary gastrointestinal tuberculosis(GTB)presenting as gastric outlet obstruction.GTB presents diagnostic challenges due to its nonspecific symptoms and lack of highly accurate diagnostic algorithms.This editorial synthesizes epidemiological data,risk factors,pathogenesis,clinical presentations,diagnostic methods,and therapies to raise awareness about GTB.GTB constitutes 1%-3%of all tuberculosis cases globally,with 6%-38%of patients also having pulmonary tuberculosis.Pathogenesis involves various modes of Mycobacterium tuberculosis complex entry into the gastrointestinal system,with the terminal ileum and ileocecal valve commonly affected.Clinical presentation varies,often resembling other intra-abdominal pathologies,necessitating a high index of suspicion.Diagnostic tools include a combination of biochemical,microbiological,radiological,and endoscopic assessments.Antitubercular medication remains the cornerstone of treatment,supplemented by surgical intervention in severe cases.Multidisciplinary management involving gastroenterologists,surgeons,pulmonologists,and infectious disease specialists is crucial for optimal outcomes.Despite advancements,timely diagnosis and management challenges persist,underscoring the need for continued research and collaboration in addressing primary GTB.
文摘Despite well-known limitations,mice remain useful as model animals to study tuberculosis(TB)pathogenesis,the basic immune response,the extent of lung pathology as well as efficacy of new drugs against Mycobacterium tuberculosis[1,2].There are four routes of tuberculosis infection in mice:aerosol generation and exposition,intravenous injection,intranasal administration,and subcutaneous administration[3].
文摘This editorial article takes an opportunity to apprehend the diagnostic challenges of primary gastrointestinal tuberculosis(an uncommon extrapulmonary tuberculosis condition)utilizing the recently published case report of a young male with prolonged gastrointestinal symptoms and weight loss who received intermittent anti-tubercular treatment and underwent operative interventions to relieve gastric outlet obstruction.The diagnosis chiefly relied on high-end examinations,like computed tomography scans and histopathological evaluation of postoperatively resected bowel tissue,which wasn't preceded by an all-inclusive stepwise primary pulmonary tuberculosis exclusion approach that usually begins with a detailed tuberculosis-pertinent history acquisition.Given the geographic locations where the patient had been(and/or treated),pivotal consideration of tuberculosis-associated endemicities in those regions,like human immunodeficiency virus(HIV)infection,might have improved the case description.The obtainment of HIV-relevant histories,like intravenous drug use and sexual practice,are good places to start.The sputum bacteriology also seems imperative to rule out atypical Mycobacterium species infection because of its clinico-radiohistopathological resemblance with pulmonary Mycobacterium tuberculosis.Altogether,this editorial aims to underscore that primary extrapulmonary tuberculosis diagnosis should comprise an elaborative,comprehensive,systematic,and stepwise primary pulmonary Mycobacterium tuberculosis exclusion workup.
文摘BACKGROUND Tuberculosis(TB)is a chronic respiratory infectious disease that considerably jeopardizes human health,and there is no effective vaccine suitable for its prevention in the entire population.AIM To investigate the promotion of medication adherence and disease cognition in patients with drug-resistant(DR-)TB using detailed nursing management.METHODS In total,114 patients with DR-TB who were diagnosed and treated at our hospital between January 2019 and January 2023 were included in this study.Patients in the control group(n=57)were managed with conventional nursing care,while those in the observation group(n=57)were managed with detailed nursing care.Medication adherence,disease awareness scores,medication safety,and nursing satisfaction were compared between the two groups after the intervention.RESULTS The post-intervention medication compliance rate was 91.23%in the observation group and 75.44%in the control group,with the former being 15.79%higher than the latter(P<0.05).There was no statistically significant difference in the disease awareness scores between the two groups before the intervention;the disease awareness scores of the observation group were significantly higher than those of the control group after the intervention(P<0.05).The incidence of gastrointestinal reactions,joint swelling and pain,hearing loss,electrolyte disorders,and liver and kidney function abnormalities were lower in the observation group than those in the control group.The total nursing satisfaction of the observation group was higher than that of the control group(P<0.05).CONCLUSION Implementation of detailed nursing management for patients with DR-TB can effectively improve medication adherence,enhance awareness of the disease,ensure safety of medication,and improve satisfaction with nursing care.
文摘Background: The community tuberculosis care program was started to reduce the impact of TB and increase successful treatment outcomes, thus contributing to meeting WHO targets on TB. According to the Botswana Ministry of Health, community tuberculosis care was introduced with the main goal of reducing tuberculosis-related morbidity and mortality among communities through the expansion of direct observed therapy and community involvement to community settings. The community caregivers were to support tuberculosis patients throughout their treatment period until they were cured or had completed their treatment. Settings: Two major cities of Botswana, Francistown and Gaborone, with more than twenty-two health clinics offering tuberculosis care. Objective: To investigate community caregivers’ experiences and identify programmatic strategies to improve active TB case findings under the community TB care (CTBC) program in Botswana during 2016-2021. Methods: We adopted a descriptive qualitative research design, followed by convenience purposive sampling. We obtained consent and interviewed 40 participants who met the inclusion criteria, 16 out of 73 in Gaborone and 24 out of 38 from Francistown. Results: We interviewed 40 caregivers with a mean age of 43.4 years. Accepting the caregiving role was identified as the main experience by more than two thirds of the caregivers. While at least more than two-fifth felt obligated to care for the patient at home due to personal relations. More than half of the respondents found caregiving difficult or frustrating due to some challenges encountered during the caregiving role. Behavioral modifications were suggested under different subthemes as strategies to improve active case finding. [-rId13-]Conclusion: Acceptance was the major experience in CTBC. Intensification of known programmatic strategies was suggested by caregivers to improve tuberculosis active case finding in CTBC.
文摘Tuberculosis(TB)remains a huge global healthcare challenge even in the 21^(st) century though the prevalence has dropped in developed countries in recent decades.Diabetes mellitus(DM)is an important risk factor for the development and perpetuation of TB owing to the immune dysfunction in patients with DM.The coexistence of both diseases in the same individual also aggravates disease severity,complications,and chance of treatment failure because of gross immune alterations posed by DM as well as TB.Various complex cellular and humoral immunological factors are involved in the dangerous interaction between TB and DM,some of which remain unknown even today.It is highly important to identify the risk factors for TB in patients with DM,and vice versa,to ensure early diagnosis and management to prevent complications from this ominous coexistence.In their research study published in the recent issue of the World Journal of Diabetes,Shi et al elaborate on the factors associated with the development of TB in a large cohort of DM patients from China.More such research output from different regions of the world is expected to improve our knowledge to fight the health devastation posed by TB in patients with diabetes.
