RESUMO
Importance: Laboratory testing for the presence of tuberculosis, hepatitis, and other conditions before starting most systemic immunomodulatory agents is recommended in patients with chronic inflammatory skin diseases (CISD) but current testing patterns in the US are unclear. Objective: To determine the prevalence of pretreatment testing that is recommended for patients with CISD (psoriasis, hidradenitis suppurativa, or atopic dermatitis). Design, Setting, and Participants: This descriptive analysis of US commercial insurance claims databases from December 31, 2002, to December 31, 2020, included adult patients with CISD (psoriasis, hidradenitis suppurativa, or atopic dermatitis) who started an immunomodulatory agent, including methotrexate, tumor necrosis factor α inhibitors, interleukin (IL)-17Ai, ustekinumab, IL-23i, dupilumab, or apremilast. Main Outcomes and Measures: The proportion of patients who underwent the screening tests as suggested by professional societies-including for tuberculosis, hepatitis, and liver function; complete blood cell counts; and lipid panels-were determined within 6 months before and during 2 years after treatment start. Results: A total of 122â¯308 patients with CISDs (median [IQR] age, 49 [38-58] years; 63â¯663 [52.1%] male) starting systemic immunomodulatory treatment in the US were included. Treatment for patients with CISDs comprised methotrexate (28â¯684), tumor necrosis factor α inhibitors (40â¯965), ustekinumab (12â¯841), IL-23i (6116), IL-17Ai (9799), dupilumab (7787), or apremilast (16â¯116). Complete blood cell count was the most common test, performed in 41% (3161/7787) to 69% (19â¯659/28â¯684) of individuals before initiation across treatments. Between 11% (889/7787) and 59% (3613/6116) of patients had tuberculosis screening within 6 months before treatment, and 3% (149/4577) to 26% (1559/6097) had updated tests 1 year later. Between 13% (1006/7787) and 41% (16â¯728/40â¯965) had hepatitis panels before treatment. Low pretreatment testing levels before apremilast (15% [2331/16â¯116] to 45% [7253/16â¯116]) persisted a year into treatment (9% [816/8496] to 36% [2999/8496]) and were similar to dupilumab (11% [850/7787] to 41% [3161/7787] vs 3% [149/4577] to 25% [1160/4577]). Conclusions and Relevance: In this descriptive analysis of patients with CISDs starting systemic immunomodulatory treatment in the US, less than 60% received the recommended pretreatment testing. Additional research is required to understand whether variations in testing affect patient outcomes.

OBJECTIVE: Reports of tuberculosis (TB) during anticancer treatment with immune checkpoint inhibitors (ICIs) are increasing. However, it is not clear whether the use of ICIs is a significant risk factor for TB, including reactivation or latent TB infection (LTBI). METHODS: To determine the risk of TB reactivation in patients with lung cancer who use ICIs or tyrosine kinase inhibitors (TKIs), we conducted a retrospective study using a hospital-based cancer registry. In addition, we monitored patients with cancer using ICI or TKI in a multicenter prospective study to check the incidence of LTBI. RESULTS: In the retrospective study, several demographic factors were imbalanced between the ICI and TKI groups: the ICI group was younger, had more males, exhibited more squamous cell carcinoma in histology rather than adenocarcinoma, had fewer EGFR mutations, and received more chemotherapy. Propensity score matching was used to control for confounding factors, and we found that the incidence of TB was higher among patients with lung cancer who received ICIs than among those who received TKIs (2298 vs 412 per 100 000 person-years, Pâ =â .0165). Through multivariable analysis, group (ICI vs TKI) was the independent risk factor for TB development (adjusted hazard ratio (aHR): 6.29, 95% CI, 1.23-32.09, Pâ =â .0269). In the prospective cohort, which included 72 patients receiving ICIs and 50 receiving TKIs, we found that the incidence of positive seroconversion of LTBI by interferon gamma release assay (IGRA) was significantly higher in patients receiving ICIs (18% vs 0%, aHR: 9.88, Pâ =â 0.035) under multivariable Cox regression. CONCLUSION: The use of ICIs may be linked to a higher likelihood of TB reactivation and LTBI than individuals solely receiving TKIs as anticancer therapy. Consequently, the implementation of a screening program for TB reactivation and LTBI among patients undergoing ICI treatment could prove advantageous by enabling early detection and prompt treatment of the infection.

OBJECTIVE: To evaluate risk of infections requiring hospitalization and opportunistic infections, including tuberculosis, in patients with rheumatoid arthritis (RA) treated with abatacept versus conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs) and other biologic/targeted synthetic (b/ts) DMARDs. METHODS: Five international observational data sources were used: two biologic registries (Sweden, Germany), a disease registry (USA) and two healthcare claims databases (Canada, USA). Crude incidence rates (IRs) per 1000 patient-years, with 95 % CIs, were used to estimate rate ratios (RRs) comparing abatacept versus csDMARDs or other b/tsDMARDs. RRs were adjusted for demographic factors, comorbidities, and other potential confounders and then pooled across data sources using a random effects model (REM). RESULTS: The data sources included 6450 abatacept users, 136,636 csDMARD users and 54,378 other b/tsDMARD users, with a mean follow-up range of 2.2-6.2 years. Across data sources, the IRs for infections requiring hospitalization ranged from 16 to 56 for abatacept, 19-46 for csDMARDs, and 18-40 for other b/tsDMARDs. IRs for opportunistic infections were 0.4-7.8, 0.3-4.3, and 0.5-3.8; IRs for tuberculosis were 0.0-8.4, 0.0-6.0, and 0.0-6.3, respectively. The pooled adjusted RR (95 % CI), only reported for infections requiring hospitalization, was 1.2 (0.6-2.2) for abatacept versus csDMARDs and 0.9 (0.6-1.3) versus other b/tsDMARDs. CONCLUSIONS: Data from this international, observational study showed similar hospitalized infection risk for abatacept versus csDMARDs or other b/tsDMARDs. IRs for opportunistic infections, including tuberculosis, were low. These data are consistent with the known safety profile of abatacept.

Background: Poor medication adherence remains one of the major problems in the treatment of tuberculosis (TB) patients, while digital technologies have been proven effective to improve the treatment results. However, reports on the effectiveness of comprehensive practice integrating different intervention methods and technologies are limited. The aim of this study is to evaluate the effectiveness of an integrated digital adherence intervention for TB patients. Methods: We developed a digital adherence intervention platform integrating instant WeChat message, electronic medication monitors (EMMs), and manual reminders. The primary goal of the platform was to improve the accessibility of digital adherence technologies, and thus improve treatment adherence. TB patients were newly diagnosed at 10 TB-designated hospitals and came from 220 communities, from January to June 2022. The basic characteristics and treatment adherence of TB patients in WeChat, EMM, and conventional groups were compared, and the influencing factors of high medication adherence were analyzed by logistic regression. Results: A total of 2,498 TB patients were enrolled in the study, 14.5% were managed by digital technologies, 9.5% by WeChat, and 5.0% by EMM, respectively. After intervention, the median medication rate of TB patients was significantly higher in the WeChat group (95.3%) and EMM group (95.7%) compared with that of the conventional group (83.8%). On the contrary, the median number of missed medications among patients of the conventional group (nine times) was significantly higher than that in the WeChat (three times) group and EMM (three times) group. The proportion of high adherence (adherence medication rate ≥90%) among TB patients was 64.7%, 64.5%, and 43.2% in WeChat, EMM, and conventional group, respectively. Conclusions: The application of the integrated digital adherence intervention platform could significantly improve medication adherence among TB patients. The accessibility of digital adherence technologies could be improved by integrating complementary technologies in practice.

Drug-induced liver injury (DILI) is an adverse outcome of the currently used tuberculosis treatment regimen, which results in patient noncompliance, poor treatment outcomes, and the emergence of drug-resistant tuberculosis. DILI is primarily caused by the toxicity of the drugs and their metabolites, which affect liver cells, biliary epithelial cells, and liver vasculature. However, the precise mechanism behind the cellular damage attributable to first-line antitubercular drugs (ATDs), as well as the effect of toxicity on the cell survival strategies, is yet to be elucidated. In the current study, HepG2 cells upon treatment with a high concentration of ATDs showed increased perforation within the cell, cuboidal shape, and membrane blebbing as compared with control/untreated cells. It was observed that ATD-induced toxicity in HepG2 cells leads to altered mitochondrial membrane permeability, which was depicted by the decreased fluorescence intensity of the MitoRed tracker dye at higher drug concentrations. In addition, high doses of ATDs caused cell damage through an increase in reactive oxygen species production in HepG2 cells and a simultaneous reduction in glutathione levels. Further, high dose of isoniazid (50-200 mM), pyrazinamide (50-200 mM), and rifampicin (20-100 µM) causes cell apoptosis and affects cell survival during toxic conditions by decreasing the expression of potent autophagy markers Atg5, Atg7, and LC3B. Thus, ATD-mediated toxicity contributes to the reduced ability of hepatocytes to tolerate cellular damage caused by altered mitochondrial membrane permeability, increased apoptosis, and decreased autophagy. These findings further emphasize the need to develop adjuvant therapies that can mitigate ATD-induced toxicity for the effective treatment of tuberculosis.

BACKGROUND: Evidence and guidelines for Non-vitamin K antagonist oral anticoagulants (NOACs) use when prescribing concurrent rifampin for tuberculosis treatment in patients with non-valvular atrial fibrillation (NVAF) are limited. METHODS: Using the Korean National Health Insurance Service database from January 2009 to December 2018, we performed a population-based retrospective cohort study to assess the net adverse clinical events (NACE), a composite of ischemic stroke or systemic embolism and major bleeding, of NOACs compared with warfarin among NVAF patients taking concurrent rifampin administration for tuberculosis treatment. After a propensity matching score (PSM) analysis, Cox proportional hazards regression was performed in matched cohorts to investigate the clinical outcomes. RESULTS: Of the 735 consecutive patients selected, 465 (63.3%) received warfarin and 270 (36.7%) received NOACs. Among 254 pairs of patients after PSM, the crude incidence rate of NACE was 25.6 in NOAC group and 32.8 per 100 person-years in warfarin group. There was no significant difference between NOAC and warfarin use in NACE (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.48-1.14; P = 0.172). Major bleeding was the main driver of NACE, and NOAC use was associated with a statistically significantly lower risk of major bleeding than that with warfarin use (HR, 0.63; 95% CI, 0.40-1.00; P = 0.0499). CONCLUSIONS: In our population-based study, there was no statically significant difference in the occurrence of NACE between NOAC and warfarin use. NOAC use may be associated with a lower risk of major bleeding than that with warfarin use.

BACKGROUND: The availability of Janus kinase (JAK) inhibitors has transformed the management of rheumatoid arthritis (RA), helping patients achieve clinical remission. However, the emergence of opportunistic infections (OIs) associated with the use of JAK inhibitors has been reported. This structured literature review was conducted to summarize reports of OIs associated with JAK inhibitor treatment for RA in clinical trials. METHODS: Structured searches were performed in MEDLINE® and Embase® to identify relevant clinical trial data through March 2021. Bibliographic searches of recent reviews were also conducted, and gray literature searches were used to supplement key gap areas. Publications were screened, extracted, and quality assessed. Data were narratively synthesized. RESULTS: Following screening, 105 publications describing 62 unique clinical trials reporting the rates of OIs in RA patients treated with JAK inhibitors were included. Overall, the highest exposure-adjusted incidence rate was reported for herpes zoster (HZ) infection (any form), followed by OI (any) and tuberculosis based on limited data from clinical trials with approved doses of JAK inhibitors. Lack of head-to-head trials and differences in trial design preclude direct comparison across JAK inhibitors. Higher rates of OIs were noted in the Asian and Australian populations compared with the global population. Higher rates of OIs were also noted with increasing dose of JAK inhibitors in most clinical trial data. CONCLUSIONS: HZ was the most common OI reported among RA patients using all currently approved JAK inhibitors in clinical trials, although tuberculosis and other OIs were also reported. More long-term safety studies in the real-world setting are needed to compare the risk of OIs between various JAK inhibitors.

Aim of study: To describe the clinical, therapeutic and evolutionary profile of patients followed for rifampicin-resistant pulmonary tuberculosis (RR-TB) at the Regional Hospital Centre (RHC) of Maradi (Niger) from 2014 to 2018. Methods: We conducted a retrospective and descriptive study based on the records of patients followed for Multidrug-resistant tuberculosis (MDR-TB) between January 1, 2014 and June 30, 2018 at the resistant tuberculosis management unit in Maradi (Niger). This unit is located within the RHC of Maradi and has a capacity of 20 beds in 4 wards. It receives patients with tuberculosis resistant to first-line anti-tuberculosis drugs. In this study, patients diagnosed with RR-TB by genotypic (GeneXpert MTB/RIF) or phenotypic (culture) testing were included. We excluded from this study: patients previously treated for more than 1 month with second-line anti-TB drugs; patients with resistance to second-line injectables (SLI) and/or fluoroquinolones (FQ); patients with an electrocardiogram QTc greater than 500 ms (the corrected QT (QTc) estimates the QT interval at a rate of 60 beats per second); cases of atypical mycobacteriosis detected by phenotypic testing.Patients were previously on 2RHZE/4RH prior to the discovery of resistance. The treatment protocol for resistant TB was as follows: 4KmMfxPtoCfzHZE/5MfxCfzZE (The second-line injectable was replaced by Lzd in case of initial or treatment-emergent deafness). HIV co-infected patients received, in addition to anti-tuberculosis drugs, antiretrovirals and cotrimoxazole in preventive doses. Results: A total of 80 patients were included in the present study (70 males and 10 females, mean age 34.4 years with extremes ranging from 18 to 71 years). Patients aged 18-35 years accounted for more than half. Patients with primary treatment failure were the most frequent type (36%) followed by patients with retreatment failure (24%) and patients with retreatment relapse (17%). It should be noted that 77 patients (96%) were previously treated for TB and only 3 patients (4%) were new cases. The majority of patients (70%) had a Body mass index of less than 18 kg/m2. 7.5% of patients were HIV positive, one was diabetic, 52% of the patients had grade 2 radiological lesions. Grade 1 deafness was noted at the beginning of treatment in 3%. A third of patients (36%) were primary treatment failures. The treatment protocol was as follows: 4KmMfxPtoCfzHZE/5MfxCfzZE. Only 1 patient had a positive culture at the end of the 4th month of treatment. Most of the patients had experienced adverse events, mainly digestive, with vomiting being the most common. The therapeutic success rate was 88%. We noted 10% of deaths, 1% of therapeutic failure and 1% of lost to follow-up.Six months after treatment, 48 patients (60%) were smear negative and 43 (54%) were culture negative. In 32 patients (40%), the smear was not performed and culture was not performed in 37. Conclusion: The short treatment regime gives satisfactory results in the absence of resistance to fluoroquinolones, with rare adverse effects. In Niger, further efforts should be made to minimize the delay in diagnosis which is responsible for most deaths during treatment. A centre could usefully be designated to organize "TB consiliums" allowing any practitioner to submit difficult cases of MDR-TB.

INTRODUCTION: Cotreatment of HIV and tuberculosis (TB) reduces morbidity and mortality in coinfected patients. Availability of antiretroviral treatment (ART) drug options, including within drug classes, is important, particularly in high HIV/TB burden low and middle-income countries. METHODS AND ANALYSIS: This is a phase 2b, open-label, non-comparative randomised controlled trial to assess the antiretroviral activity of a fixed-drug, single tablet, combination of bictegravir (BIC) 50 mg/emtricitabine (FTC) 200 mg/tenofovir alafenamide (TAF) 25 mg (Biktarvy). The primary objective is to determine the efficacy, safety and pharmacokinetics of two times per day, coformulated BIC 50 mg/FTC 200 mg/TAF 25 mg in HIV-positive ART-naïve patients with TB who are receiving a rifampicin-based treatment regimen and to characterise viral suppression rates at week 24 through to week 48 in the BIC/FTC/TAF arm. We will enrol 120 patients randomised in a 2:1 ratio to the intervention or control arm of the study. A non-comparative contemporaneous control arm in which participants receive a dolutegravir-based regimen (standard of care) will also be enrolled. ETHICS AND DISSEMINATION: The University of KwaZulu-Natal Biomedical Research Ethics Committee (BREC) and the South African Health Products Regulatory Authority (SAHPRA) have granted regulatory approval (trial reference numbers: BREC/00001300/2020 and SAHPRA 20200810). Trial results will be disseminated through conference presentations, peer-reviewed publications and the clinical trial registry. TRIAL REGISTRATION NUMBER: Clinicaltrials.gov; Trial registration number: NCT04734652; South African National Clinical Trials Register (SANCTR DOH-27-012021-6789).

BACKGROUND: Prior to dolutegravir availability, ritonavir-boosted lopinavir (LPV/r) was an alternative recommendation when first-line drugs could not be used. A high concentration of protease inhibitors was observed in the Thai people living with HIV (PLWH). Thus, dose reduction of LPV/r may be possible. However, the pharmacokinetics and dose optimization of LPV/r have never been investigated. This study aimed to develop a population pharmacokinetic model of LPV/r and provide dosage optimization in Thai PLWH. METHODS: LPV and RTV trough concentrations from Thai PLWH were combined with intensive data. The data were analyzed by the nonlinear mixed-effects modeling approach. The influence of RTV concentration on LPV oral clearance (CL/F) was investigated. RESULTS: Rifampicin (RIF) use increased LPV and RTV CL/F by 2.16-fold and 1.99-fold, respectively. The reduced dose of 300/75 and 200/150 mg twice daily provided a comparable percentage of patients achieving LPV target trough concentration to the standard dose for PI-naïve patients. For HIV/TB co-infected patients receiving RIF who could not tolerate the recommended dose, the reduced dose of 600/150 mg twice daily was recommended. CONCLUSION: The population pharmacokinetic model was developed by integrating the interaction between LPV and RTV. The reduced LPV/r dosage offers sufficient LPV exposure for Thai PLWH.

Tuberculosis (TB) still remains the burden in Indonesia. One of the factors that may influence the treatment success of TB is patient's adherence. However, the hepatotoxicity of the TB medicine may decrease the patient's adherence. Our study's aim is to investigate the relationship between the patient's knowledge and the hepatotoxicity with medication adherence of TB patients in Banyumas Regency. This study was conducted at one Community Lung Health Center and two hospitals in Banyumas Regency, Purwokerto, Center of Java, Indonesia. The respondents were 91 TB patients with hepatotoxicity characterized by an increased aspartate transaminase (AST) and alanine aminotransferase (ALT). The level of the patients' knowledge about the hepatotoxicity effect was determined using a questionnaire. The patients' adherence was determined using the Medication Adherence Rating Scale -5 (MARS) questionnaire and pill count methods. Most of the patients were male (53.8%), the age was in the range of 18-29 years old (3.5%), they have no smoking history (59.3%), and their last education majorly was senior high school (46.2%). Most TB patients had poor knowledge (47.3%) and the hepatotoxic effect often appeared in grade 1 (61.5%). The TB patients with a good and moderate level of knowledge were 17.6% and 35.2%, respectively. The TB patients with moderate and severe hepatotoxicity were 39.4% and 1.1%, respectively. The measurement of the level of respondents' adherence using MARS-5 showed that 51.6% of patients had good adherence. We determined the rest of the drug-using pill count method, which resulted in 62.6% of patients adhering to taking antituberculosis drugs. TB patients with a sufficient knowledge and those with mild hepatotoxicity show the higher adherence (p < 0.001). There is a significant relationship between a high level of the patient's knowledge about hepatotoxicity effect, less severity of the hepatotoxic effect, and increased patient adherence in taking the medication.

BACKGROUND: Tumor necrosis factor (TNF) inhibitors increase the risk of tuberculosis (TB) in patients with rheumatoid arthritis (RA). This study compared the incidence of TB after treatment with TNF inhibitors and tocilizumab in patients with RA, separately in those who were treated for latent tuberculosis infection (LTBI) and those without evidence of LTBI. METHODS: This study included patients with RA who initiated TNF inhibitors and tocilizumab between December 2013 and August 2018. Patient data were collected from the nationwide database of the Health Insurance Review and Assessment service in South Korea. The incidence of TB was compared among different biologic drugs in patients with or without LTBI treatment. RESULTS: Of 4736 patients, 1168 were treated for LTBI and 48 developed TB (554.9 per 100,000 person-years). When compared based on etanercept, infliximab showed a higher risk of TB (adjusted incidence rate ratio 2.71, 95% confidence interval 1.05-7.01), especially in patients without evidence of LTBI. Other TNF inhibitors and tocilizumab showed a comparable incidence of TB, regardless of treatment for LTBI. There was no significant difference in TB incidence after biologic therapy between patients with and without LTBI treatment (627.9/100,000 vs. 529.5/100,000 person-years). In patients treated for LTBI, no differential risk of TB was observed among biologic drugs. CONCLUSIONS: The incidence of TB was not significantly different among biologic drugs in the current era, except for infliximab in patients who were not treated for LTBI. Treatment of LTBI might alleviate the drug-specific risk of TB in patients with RA.

WHAT IS KNOWN AND OBJECTIVE: The pathogenic mechanism of anti-tuberculosis drug-induced liver injury (AT-DILI) is still largely unknown. Recent studies have indicated that rifampicin and isoniazid cotreatment causes the accumulation of endogenous protoporphyrin IX in the liver through the haem biosynthesis pathway. Alanine synthase 1 (ALAS1) and ferrochelatase (FECH) are the rate-limiting enzymes in the production of haem. The present study aimed to investigate the genetic contribution of the ALAS1 and FECH genes to the risk of AT-DILI in an Eastern Chinese Han population. METHODS: A 1:4 matched case-control study was conducted, and eight SNPs in the ALAS1 and FECH genes were detected and assessed. A multivariate conditional logistic regression model was used to estimate the association between genotypes and the risk of AT-DILI by the odds ratios (ORs) with 95% confidence intervals (CIs), with liver disease history, hepatoprotectant use, smoking and drinking history as covariates. RESULTS AND DISCUSSION: Overall, 202 AT-DILI cases and 808 controls were included in this study. The female patients carrying polymorphisms of rs11660001 in FECH had an increased risk of AT-DILI under the dominant and additive models (OR = 1.831, 95% CI: 1.014-3.307, p = 0.045; OR = 1.673, 95% CI: 1.015-2.760, p = 0.044, respectively). The peak aspartate transaminase level was significantly higher in female patients carrying the GA+AA genotype of rs11660001 than in those with the GG genotype during anti-TB treatment (p = 0.032). WHAT IS NEW AND CONCLUSION: Based on this 1:4 individual matched case-control study, SNP rs11660001 in the FECH gene may be associated with susceptibility to AT-DILI in Chinese female anti-TB treatment patients. Further studies in larger varied populations are needed to validate our findings.

INTRODUCTION: Increased dosing of rifampicin and pyrazinamide seems a viable strategy to shorten treatment and prevent relapse of drug-susceptible tuberculosis (TB), but safety and efficacy remains to be confirmed. This clinical trial aims to explore safety and pharmacokinetics-pharmacodynamics of a high-dose pyrazinamide-rifampicin regimen. METHODS AND ANALYSIS: Adult patients with pulmonary TB admitted to six hospitals in Sweden and subjected to receive first-line treatment are included. Patients are randomised (1:3) to either 6-month standardised TB treatment or a 4-month regimen based on high-dose pyrazinamide (40 mg/kg) and rifampicin (35 mg/kg) along with standard doses of isoniazid and ethambutol. Plasma samples for measurement of drug exposure determined by liquid chromatography tandem-mass spectrometry are obtained at 0, 1, 2, 4, 6, 8, 12 and 24 hours, at day 1 and 14. Maximal drug concentration (Cmax) and area under the concentration-time curve (AUC0-24h) are estimated by non-compartmental analysis. Conditions for early model-informed precision dosing of high-dose pyrazinamide-rifampicin are pharmacometrically explored. Adverse drug effects are monitored throughout the study and graded according to Common Terminology Criteria for Adverse Events V.5.0. Early bactericidal activity is assessed by time to positivity in BACTEC MGIT 960 of induced sputum collected at day 0, 5, 8, 15 and week 8. Minimum inhibitory concentrations of first-line drugs are determined using broth microdilution. Disease severity is assessed with X-ray grading and a validated clinical scoring tool (TBscore II). Clinical outcome is registered according to WHO definitions (2020) in addition to occurrence of relapse after end of treatment. Primary endpoint is pyrazinamide AUC0-24h and main secondary endpoint is safety. ETHICS AND DISSEMINATION: The study is approved by the Swedish Ethical Review Authority and the Swedish Medical Products Agency. Informed written consent is collected before study enrolment. The study results will be submitted to a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT04694586.

INTRODUCTION: Screening and treatment of latent tuberculosis infections (LTBI) are required before starting biologics in patients with immune-mediated inflammatory diseases (IMIDs). This study aimed to assess the safety of LTBI treatment in older patients with IMIDs. METHODS: The medical records of 916 patients treated for LTBI before the start of biologics for IMIDs between January 2004 and December 2018 were reviewed. The safety profiles of LTBI treatment were retrospectively compared according to age. RESULTS: Among the 916 patients, 201 were aged > 60 years (older age group). The older age group showed female predominance, more frequent history of previous tuberculosis, and more comorbidities, and received biologics mainly for rheumatoid arthritis. Most patients (74.0%) took isoniazid and rifampicin daily for 3 months. The treatment completion rate was 90.4% in the overall population and was lower in the older age group (91.9% vs. 85.1%, P = 0.005). Adverse drug events were more frequent in the older age group (22.9% vs. 9.8%, P < 0.001); however, differences were mainly observed for nausea (5.5% vs. 2.1%, P = 0.016) and flu-like syndrome (6.5% vs. 1.7%, P = 0.001), but not hepatotoxicity. CONCLUSION: LTBI treatment is generally safe in older patients with IMIDs, especially with respect to hepatotoxicity. Key points ⢠The older age group had significantly more nausea and flu-like syndrome but not hepatotoxicity, compared to the younger age group. ⢠LTBI treatment was acceptable and generally safe in the older age group.

BACKGROUND: Diabetes mellitus (DM) and tuberculosis (TB) have been recognized as reemerging epidemics, especially in developing countries. Among all the risk factors, diabetes causes immunosuppression, increasing the risk of active TB three times. Vitamin D has been found as a link between DM-TB co-morbidity. OBJECTIVE: Vitamin D affects the immune response, suppresses Mycobacterium tuberculosis (Mtb) growth, and affects insulin secretion. The present systematic review determines the effect of vitamin D supplementation on clinical and therapeutic outcomes of DM-TB patients. METHOD: A comprehensive literature search was carried out in PubMed, Cochrane, Web of Science, and Scopus database to determine eligible studies from inception to January 2021. Out of the 639 articles retrieved, three randomized controlled trials (RCTs) were included in the systematic review. RESULT: The effect of vitamin D3 or oral cholecalciferol supplementation was assessed on outcomes, such as duration to sputum smear conversion, TB scores improvement, change in glycemic parameters, including HbA1c, FBS, and PLBS, and laboratory parameters, such as Hb, ESR, and CRP. Duration of sputum smear conversion was decreased by two weeks in the vitamin D3 supplemented group in two studies. TB score improvement and changes in glycemic parameters were inclined towards supplemented group; however, they were not significant. CONCLUSION: The overall effect of vitamin D3 supplementation on TB patients with DM was not significant. Further studies are required in the future examining the effect of supplementation on outcomes in this population.

En los últimos años, ha habido un aumento sostenido del uso de terapias inmunomoduladoras como las terapias biológicas y en un período más reciente, de las terapias con moléculas pequeñas. Estos tratamientos constituyen un factor de riesgo más para enfermar de tuberculosis en adultos y aunque en menor grado, también en niños, especialmente con el uso de anti TNF-α, por lo que antes de iniciar una terapia biológica, hay que descartar la tuberculosis activa y la latente. En el tratamiento de una tuberculosis activa producida por un biológico se debe prolongar la etapa de continuación a 9 meses. Es importante el seguimiento clínico prolongado en años de quienes usan o han completado el uso de estas terapias. Hay que posponer la vacunación BCG en los hijos de madres que usaron terapias biológicas durante la gestación hasta la edad 6 a 12 meses de los niños. El foco de esta revisión está centrado en la tuberculosis por progresión de una forma latente a una activa o por un contacto estrecho con una persona con tuberculosis pulmonar en pacientes que reciben terapias biológicas anti TNF alfa de uso inmunoreumatológico.
In recent years, there has been a sustained increase in the use of immunomodulatory therapies such as biologic therapies and, more recently, small molecule therapies. Those therapies have become another risk factor for tuberculosis in adults and, although to lesser degree, also in children, especially some of them, such as anti-TNF α. Before starting biological therapy, active tuberculosis and latent tuberculosis must be ruled out. In the treatment of active tuberculosis caused by a biologic, the continuation stage should be extended to 9 months. Long-term clinical follow-up in years of those who use them or have completed their use, is important. BCG vaccine should be postponed in children of mother who used biologic therapies during pregnancy until the children Ìs age 6 to 12 months. The focus of this review is centered on tuberculosis due to progression from a latent to an active form or due to close contact with a person with pulmonary tuberculosis in patients receiving anti-TNF alpha biological therapies for immunorheumatology use.

BACKGROUND: Despite the evolution of biologic agents, the use of traditional systemic immunosuppressants still account for a considerable proportion of systemic anti-psoriasis therapy. The risk of tuberculosis among psoriasis patients receiving such conventional immunosuppressants is not clearly understood. METHODS AND MATERIALS: We used the retrospectively-collected data from the Taiwan National Health Insurance Research Database to perform this prospective cohort study. We included 94,585 adult patients with newly diagnosed psoriasis between January 1, 2001 and December 31, 2013. We documented the exposure of systemic anti-psoriasis therapies. The outcome is incident mycobacterium tuberculosis infection. RESULTS: During a mean 6.8 years follow-up, 703 (0.74%) incident tuberculosis was diagnosed and treated. The crude incidence of tuberculosis was 1.11 (95% confidence interval [CI] 1.03-1.19) events per 1000 person-years. The result demonstrated that MTX (Hazard ratio [HR] 2.16, 95% CI 1.47-3.16) and tacrolimus (HR 5.31, 95% CI 1.66-17.01) were significantly associated with increased risks of tuberculosis. Noticeably, azathioprine was a borderline significant risk factor of tacrolimus (HR 2.63, 95% 0.96-7.21, P = 0.059). The risk of TB in patients receiving adalimumab was twofold (HR 2.07) though not significant because of only one TB event was detected. The steroid was also associated with a dose-dependent increase of tuberculosis risk (HR 1.09, 95% CI 1.09-1.12, for every 1 mg of prednisolone equivalent dose per day). CONCLUSION: The study found that among systemic anti-psoriasis therapy, methotrexate, tacrolimus, azathioprine and steroid may be associated with an increased risk of tuberculosis.

BACKGROUND: Pralsetinib, an RET inhibitor, has shown a dramatic response in patients with RET fusion- or mutation-positive tumours in previous studies. As a novel target agent, however, the safety of pralsetinib remains to be determined. Herein, we present two cases of extrapulmonary tuberculosis (TB) that developed during pralsetinib therapy. METHODS: From April 2020, we administered pralsetinib to a total of 10 patients with RET fusion-positive non-small cell lung cancer under the compassionate use program. We retrospectively analysed the clinical efficacy of and adverse events related to pralsetinib therapy. RESULTS: Of the nine patients with measurable lesions, seven achieved a partial response. Additionally, one patient without measurable lesions also showed a clinical response. As of January 8, 2021, nine patients were still receiving pralsetinib therapy, while only one had discontinued pralsetinib therapy. Most adverse events were mild and manageable. However, two patients experienced extrapulmonary TB shortly after starting pralsetinib. The disease was well controlled with anti-TB medication, and the cancer lesions were managed through ongoing pralsetinib therapy. CONCLUSION: The development of TB during pralsetinib therapy is worth noting, although further large studies are required to demonstrate definitive relationship between causality and underlying mechanism.

BACKGROUND: While some recent studies have reported the development of tuberculosis (TB) in patients exposed to immune checkpoint inhibitors (ICIs), there is limited evidence to date. Therefore, we evaluated the risk of TB in patients with cancer exposed to ICIs using the National Health Insurance claims data in South Korea. METHODS: Patients with diagnostic codes for non-small cell lung cancer, urothelial carcinoma or melanoma between August 2017 and June 2019 were identified. The incidence rate and standardized incidence ratio (SIR) of TB were calculated for both the ICI exposure and non-exposure groups. The risk of TB according to ICI exposure was assessed using a multivariable Cox regression model. RESULTS: During the study period, 141 550 patients with cancer and 916 new TB cases were identified. Among the 5037 patients exposed to ICIs, 20 were diagnosed with TB at a median of 2.2 months after the ICI was initiated. The crude incidence rate of TB per 100,000 person-years was 675.8 (95% CI 412.8 to 1043.8) for the ICI exposure group and 599.1 (95% CI 560.5 to 639.6) for the non-exposure group. The SIR for TB was 8.1 (95% CI 8.0 to 8.2) in the ICI exposure group. After adjusting for potential confounding factors, ICI treatment was not significantly associated with an increased risk of TB (HR: 0.73; 95% CI 0.47 to 1.14). CONCLUSIONS: While the incidence of TB in cancer patients exposed to ICIs was eightfold higher than in the general population, the risk of patients with cancer developing TB did not significantly differ according to ICI exposure.
