Tuberculosis (TB) remains a significant global health challenge, with the World Health Organization (WHO) aiming for a 95% reduction in TB deaths by 2030. Disparities in TB detection persist, particularly regarding gender, immigration status, and resistance patterns. In Calabria, Italy—a key entry point for migrants from high-TB-incidence regions—TB poses a notable public health risk. This multicenter, retrospective study examines newly diagnosed TB cases in Calabria from 2012 to 2023, focusing on rifampicin-resistant TB (RR-TB).
During this period, 800 TB cases were diagnosed, with 270 (33.7 %) in native-born Italians and 530 (66.2 %) in foreign-born individuals, showing significant differences in age (p < 0.001) and gender (p = 0.013). Among 685 patients of this cohort with available HIV status, 24 (3.5 %) were people living with HIV (PLWH), primarily from Africa, and diagnosed at higher rates of RR-TB (p < 0.001). TB cases varied by province, correlating with specific birthplaces. A total of 27 (3.4 %) RR-TB cases were identified, with heightened resistance to multiple drugs. Among these strains, 20 (74.1 %) were isoniazid-resistant (MDR-TB).
This study underscores the need for comprehensive TB control strategies, especially regarding co-infection with HIV and the emergence of drug-resistant strains, emphasizing the importance of early detection and tailored management in Southern Italy.

Lepra reactions are acute episodic inflammatory reactions that occur during illness due to abrupt changes in the body’s immunological response against Mycobacterium leprae. These are of two types, type 1 and type 2. Type 2 reaction is also called Erythema Nodosum Leprosum (ENL).
The common skin lesion in ENL is a red, tender, raised lesion. Subcutaneous nodules can also appear. The skin lesions may present as vesicles, pustules, or bulla. They can also develop ulcers and become necrotic. Some patients may experience skin lesions that resemble those seen in erythema multiforme. A rare desquamative rash may occur, which needs to be differentiated from a drug-related rash. Healing lesions may leave scars that may become inflamed during ENL flare-ups. In rare instances, there may be no skin lesions suggesting ENL.
Reactive perforating type of erythema nodosum leprosum (ENL) is a rare type 2 lepra reaction occurrence, observed in lepromatous leprosy and borderline lepromatous cases. It is linked with the involvement of several organs, so if diagnosis and treatment are delayed, it can result in complications and a grim prognosis.

Pregnancy and HIV affect CD4+ T lymphocytes and impact performance of QuantiFERON-TB Gold (QFT). We compared the results of QFT with QuantiFERON-TB Gold Plus (QFT-Plus), which also measures CD8+ responses to TB antigens, during pregnancy and postpartum.
Methods
We screened 516 pregnant women for TB infection (TBI) with IGRA. From 165 IGRA + pregnant women, QFT vs QFT-Plus results were compared at delivery and postpartum. Longitudinal changes in QFT-Plus were assessed in 74 pregnant women who received QFT-Plus testing at pregnancy, delivery, and postpartum.
Results
Through cross-sectional analysis of the IGRA + cohort, QFT-Plus showed higher positivity than QFT (80 % vs 65 %, p = 0.04) at delivery but no difference postpartum. Among 35 women with HIV, QFT-Plus returned more positive results than QFT at delivery and postpartum (76 % vs 47 %, p = 0.08; 90 % vs 80 %, p = 0.54), though not statistically significant. Longitudinally, QFT-Plus positivity by TB1 or TB2 was highest antepartum vs. delivery and postpartum (74 % vs. 58 % vs. 62 %; p = 0.09) and performed better than TB1 alone (100 % vs 90 %, p = 0.04) in women without HIV but not in women with HIV.
Conclusions
Performance of QFT-Plus was consistent across pregnancy, including at delivery when QFT positivity is lower. QFT-Plus may enhance antenatal TBI detection among pregnant women.
背景:妊娠和HIV影响CD4+ T淋巴细胞,影响QuantiFERON-TB Gold (QFT)的性能。我们将QFT的结果与QuantiFERON-TB Gold Plus (QFT-Plus)的结果进行了比较,QFT-Plus也测量了CD8+在怀孕和产后对TB抗原的反应。方法:采用IGRA对516例孕妇进行TB感染筛查。在165名IGRA阳性孕妇中,比较了QFT和QFT- plus在分娩和产后的结果。对74名在怀孕、分娩和产后接受QFT-Plus检测的孕妇进行QFT-Plus的纵向变化评估。结果:通过IGRA +队列的横断面分析,分娩时QFT- plus的阳性率高于QFT (80% vs 65%, p = 0.04),但产后无差异。在35名感染艾滋病毒的妇女中,QFT- plus在分娩和产后的阳性结果比QFT更多(76%比47%,p = 0.08;90% vs 80%, p = 0.54),但没有统计学意义。纵向上,TB1或TB2的QFT-Plus阳性在产前、分娩和产后最高(74%、58%、62%;p = 0.09),并且在未感染艾滋病毒的妇女中优于单独使用TB1 (100% vs 90%, p = 0.04),而在感染艾滋病毒的妇女中则不然。结论:QFT- plus的表现在整个怀孕期间是一致的,包括在分娩时,QFT阳性较低。QFT-Plus可能提高孕妇产前TBI的检测。

Background
Patients with tuberculous meningitis (TBM) are at high risk of ischemic stroke, and stroke is a poor prognosticator of TBM. However, reports regarding the predictors of stroke in TBM patients are scanty. The aim of this study was to investigate the clinical characteristics and predictors of tuberculous meningitis-related ischemic stroke (TBMRIS).
Methods
This retrospective study was conducted among TBM patients without traditional vascular risk factors from a tertiary care hospital between January 2017 and November 2022. Patients were divided into TBMRIS group and TBM-only group according to presence of stroke. Clinical, laboratory and radiological variables were compared between the two groups. Predictors of stroke were identified using binary logistic regression analysis.
Results
A total of 176 TBM patients were included in the study. Forty-nine patients with stroke were classified as TBMRIS group and 127 patients without stroke were classified as TBM-only group. In TBMRIS group, 41 (83.7 %) patients experienced stroke within 3 months after the onset of meningitis symptoms and 10 (20.4 %) patients presented silent stroke. Stroke occurred in basal ganglia in 57.1 % of patients. About 73.5 % of patients showed multiple stroke lesions and 38.8 % of patients had stroke involving multiple vascular territories. There were significant differences in focal neurological deficit, stage of meningitis, short-term outcome, serum sodium, cerebrospinal fluid (CSF) white cell count, CSF adenosine deaminase (ADA), CSF protein, leptomeningeal enhancement, tuberculoma between TBMRIS group and TBM-only group. Binary logistic regression analysis revealed that focal neurological deficit, CSF white cell count and leptomeningeal enhancement were the independent risk factors for stroke, and tuberculoma was negatively correlated with stroke.
Conclusion
Most of TBMRIS develop within 3 months after the onset of meningitis symptoms and basal ganglia is the most frequent site. Multiple stroke lesions and involvement of multiple vascular territories are commonly observed. Focal neurological deficit, CSF white cell count and leptomeningeal enhancement are the predictors of stroke in patients with TBM.

Tuberculosis (TB) is a chronic respiratory infectious disease caused by Mycobacterium tuberculosis, typically diagnosed through sputum smear microscopy for acid-fast bacilli (AFB) to assess the infectivity of TB.
Methods
This study enrolled 769 patients, including 641 patients from the First Affiliated Hospital of Guangxi Medical University as the training group, and 128 patients from Guangxi Hospital of the First Affiliated Hospital of Sun Yat-sen University as the validation group. Among the training cohort, 107 patients were AFB-positive, and 534 were AFB-negative. In the validation cohort, 24 were AFB-positive, and 104 were AFB-negative. Blood samples were collected and analyzed using machine learning (ML) methods to identify key factors for TB diagnosis.
Results
Several ML methods were compared, and support vector machine recursive feature elimination (SVM-RFE) was selected to construct a nomogram diagnostic model. The area under the curve (AUC) of the diagnostic model was 0.721 in the training cohort and 0.758 in the validation cohort. The model demonstrated clinical utility when the threshold was between 38% and 94%, with the NONE line above the ALL line in the decision curve analysis.
Conclusion
We developed a diagnostic model using multiple ML methods to predict AFB results, achieving satisfactory diagnostic performance.

The COVID-19 pandemic created unprecedented challenges in the field of global health. Nigeria, Indonesia and India are three high tuberculosis (TB) burden countries with large private health sectors. Both TB and the private health sector faced challenges in these countries because of COVID-19. This study aimed to compare the COVID-19 control measures and policies in the provision of TB care services and gain insights from policymakers on how the pandemic affected the provision of TB services in the private healthcare sector, how each country adapted, and identify lessons learned for health system preparedness.
Methods
Qualitative, in-depth interviews were conducted among a purposive sample of 11 national and sub-national policymakers in each country. Thematic content analysis was conducted on the data collected using an adapted WHO Health Equity Policy Framework.
Results
Results revealed three policy dimensions under costs, access, and quality. Under healthcare costs, policymakers highlighted resource allocation and diversion of TB resources to COVID response, and increased operational costs for private provider. Under healthcare access, key themes included reduced TB case detection due to fear of COVID-19, disrupted diagnostic services, and adaptations such as extended medicine supplies and tele-consultations. Under healthcare quality, themes included compromised TB diagnostic accuracy due to similar respiratory symptoms with COVID-19, and strain on laboratory infrastructure due to competing demands from both diseases. Policymakers across the three countries pointed to the need for strengthening private–public partnerships (PPP) for healthcare service delivery and continued private sector investment to facilitate the continuity of TB care within a pandemic context.
Conclusion
The results of this study provide an overview of the impact of the pandemic from the perspective of private facilities and policymakers in Nigeria, Indonesia and India, which can inform future policy and ways forward in strengthening PPP for healthcare service delivery in high TB burden countries.

Thematic content analysis was conducted on the data collected using an adapted WHO Health Equity Policy Framework.</div></div><div><h3>Results</h3><div>Results revealed three policy dimensions under costs, access, and quality. Under healthcare costs, policymakers highlighted resource allocation and diversion of TB resources to COVID response, and increased operational costs for private provider. Under healthcare access, key themes included reduced TB case detection due to fear of COVID-19, disrupted diagnostic services, and adaptations such as extended medicine supplies and tele-consultations. Under healthcare quality, themes included compromised TB diagnostic accuracy due to similar respiratory symptoms with COVID-19, and strain on laboratory infrastructure due to competing demands from both diseases. Policymakers across the three countries pointed to the need for strengthening private–public partnerships (PPP) for healthcare service delivery and continued private sector investment to facilitate the continuity of TB care within a pandemic context.</div></div><div><h3>Conclusion</h3><div>The results of this study provide an overview of the impact of the pandemic from the perspective of private facilities and policymakers in Nigeria, Indonesia and India, which can inform future policy and ways forward in strengthening PPP for healthcare service delivery in high TB burden countries.</div></div>","PeriodicalId":37942,"journal":{"name":"Journal of Clinical Tuberculosis and Other Mycobacterial Diseases","volume":"38 ","pages":"Article 100503"},"PeriodicalIF":1.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11697125/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
