Abstract
INTRODUCTION Tuberculosis is one of the infectious diseases with greater morbidity and mortality worldwide. Cancer causes an important immunosuppression with increased risk of infections. There is an enlarged bidirectional incidence between tuberculosis and cancer, mainly due to latent tuberculosis. GUIDELINES REVIEW There is great discrepancy between recommendations for screening and prophylaxis of latent tuberculosis in patients with solid tumors and systemic cancer therapy among different medical societies and guidelines. Most infectious diseases guidelines recommend it, while most oncology guidelines do not. DISCUSSION Patients with solid tumours generally have a limited life expectancy and a state of intermittent immunosuppression, resulting in a lower risk of tuberculosis reactivation than other risky populations. There is a lack of prospective and retrospective studies analysing the benefit of screening and prophylaxis in this population. The first step is to study the incidence of active tuberculosis in this population to estimate the real magnitude of the problem.

Abstract
A 78-year-old man with a previous diagnosis of rheumatoid arthritis on prolonged treatment with corticosteroids presented with intense and progressive pain at the cervical level that prevented him from resting his head and walking, in addition to an ulcerative lesion covering 80% of the lingual area that was previously treated as oral candidiasis without improvement. On arrival, with no clinical or serological data of rheumatoid arthritis, immunosuppressive treatment was suspended, and a biopsy of the oral cavity was requested, confirming the diagnosis of lingual tuberculosis, an extremely rare disease, occurring in less than 1% of extrapulmonary cases. MRI of the cervical spine showed a crush fracture of the C6 and C7 bodies associated with spondylitis of probably infectious etiology that required surgical treatment, and histopathological studies confirmed Pott's disease. The patient displayed no evidence of pulmonary tuberculosis from arrival until the end of the follow-up.

Abstract
Glucocorticoids are commonly used for neurological disorders, but they can have significant adverse effects, including adrenal insufficiency, hyperglycaemia, osteoporosis and increased infection risk. Long-term use of corticosteroids requires the prescriber to plan risk mitigation, including monitoring and often coprescribing. This article highlights the potential risks of corticosteroid prescribing and draws together up-to-date guidance with multispecialty input to clarify ways of reducing those risks. We discuss home blood glucose monitoring and consider a steroid safety checklist to promote safer steroid prescribing.

Abstract
OBJECTIVES This study aimed to evaluate the risk of tuberculosis associated with the use of Janus kinase (JAK) inhibitors or biological disease-modifying antirheumatic drugs (bDMARDs) in patients diagnosed with rheumatoid arthritis (RA) in South Korea. METHODS In this nationwide matched-cohort study, we retrospectively identified adult patients with new-onset RA from the National Health Insurance Service database who were prescribed bDMARDs or JAK inhibitors and recently underwent latent tuberculosis infection (LTBI) screening during 2012‒2021, and followed them up until the end of 2022 for the development of active tuberculosis. HRs were estimated using Cox proportional hazards regression in a propensity score-matched cohort. RESULTS Among 16 760 matched patients with RA (3352 JAK inhibitor users and 13 408 bDMARD users), 18.8% received tuberculosis preventive therapy for LTBI. Overall, JAK inhibitor users had a significantly lower risk of tuberculosis than bDMARD users (HR (95% CI)=0.37 (0.22 to 0.62)). Among the patients treated for LTBI, patients with low treatment adherence had a significantly higher risk than those without LTBI (HR (95% CI)=2.78 (1.74 to 4.44)). Patients without LTBI and using JAK inhibitors had a significantly lower risk of tuberculosis across all ages and sexes compared with bDMARD users. CONCLUSION Patients with RA using JAK inhibitors have a significantly lower risk of active tuberculosis than bDMARD users in South Korea; however, patients with RA having LTBI are equally at risk regardless of the treatment received (JAK inhibitor vs bDMARD). Therefore, vigilant tuberculosis monitoring, especially in patients with low adherence to tuberculosis preventive therapy, is essential.

Abstract
Glucocorticoids are widespread anti-inflammatory medications used in medical practice. The immunosuppressive effects of systemic glucocorticoids and increased susceptibility to infections are widely appreciated. However, the dose-dependent model frequently used may not accurately predict the risk of infection in all patients treated with long-term glucocorticoids. In this review, we examine the risks of opportunistic infections (OIs) in patients requiring glucocorticoid therapy by evaluating the influence of the glucocorticoid dose, duration, and potency, combined with biological and host clinical factors and concomitant immunosuppressive therapy. We propose strategies to prevent OIs, which involve screening, antimicrobial prophylaxis, and immunizations. While this review focuses on patients with autoimmune, inflammatory, or neoplastic diseases, the potential risks and preventative strategies are likely applicable to other populations. Clinicians should actively assess the benefit-harm ratios of systemic glucocorticoids and implement preventive efforts to decrease their associated infections complications.

Risk Factors for Infectious Complications following Endoscopic Retrograde Cholangiopancreatography in Liver Transplant Patients: A Single-Center Study. J Clin Med 2024; 13:1438. [PMID: 38592264 PMCID: PMC10934434 DOI: 10.3390/jcm13051438] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 02/27/2024] [Accepted: 02/28/2024] [Indexed: 04/10/2024] Open
Abstract
Background: Liver transplant recipients often require endoscopic retrograde cholangiopancreatography (ERCP) for biliary complications, which can lead to infections. This retrospective single-center study aimed to identify risk factors for infectious complications following ERCP in liver transplant patients. Methods: A retrospective analysis was conducted on 285 elective ERCP interventions performed in 88 liver transplant patients at a tertiary care center. The primary endpoint was the occurrence of an infection following ERCP. Univariable and multivariable regression analyses, Cox regression, and log-rank tests were employed to assess the influence of various factors on the incidence of infectious complications. Results: Among the 285 ERCP interventions, isolated anastomotic stenosis was found in 175 cases, ischemic type biliary lesion (ITBL) in 103 cases, and choledocholithiasis in seven cases. Bile duct interventions were performed in 96.9% of all ERCPs. Infections after ERCP occurred in 46 cases (16.1%). Independent risk factors for infection included male sex (OR 24.19), prednisolone therapy (OR 4.5), ITBL (OR 4.51), sphincterotomy (OR 2.44), cholangioscopy (OR 3.22), dilatation therapy of the bile ducts (OR 9.48), and delayed prophylactic antibiotic therapy (>1 h after ERCP) (OR 2.93). Additionally, infections following previous ERCP interventions were associated with an increased incidence of infections following future ERCP interventions (p < 0.0001). Conclusion: In liver transplant patients undergoing ERCP, male sex, prednisolone therapy, and complex bile duct interventions independently raised infection risks. Delayed antibiotic treatment further increased this risk. Patients with ITBL were notably susceptible due to incomplete drainage. Additionally, a history of post-ERCP infections signaled higher future risks, necessitating close monitoring and timely antibiotic prophylaxis.

Abstract
Patients with inflammatory rheumatic diseases have a higher risk of infections in comparison to the general population. For this patient group, in addition to cardiovascular diseases, infections play an important role with respect to morbidity and mortality. Even if it is difficult to make concrete statements with respect to individual diseases, it can be assumed that there is a lower risk of infections in inflammatory joint diseases in comparison to connective tissue diseases and vasculitides. The increased risk of infections is determined by multiple factors, whereby the underlying factors are classified into three main categories: patient-related factors (age, comorbidities, lifestyle), disease-related factors (immunological dysfunction as part of the disease pathophysiology) and drug-related factors (type and dosage of the immunosuppression and/or immunomodulation). An improved understanding of the complexity of these associations enables the optimization of treatment and disease control taking the individual risk factors into account, with the aim of a significant reduction in the risk of infections.

Abstract
BACKGROUND Dupilumab efficacy and safety in children aged 6-11 years with uncontrolled, moderate-to-severe asthma were shown in the VOYAGE study-a 52-week, multinational, multicentre, phase 3 randomised, double-blind, placebo-controlled trial. We aimed to evaluate the long-term safety and efficacy of dupilumab in children with moderate-to-severe asthma who previously participated in the VOYAGE study. METHODS 365 of 408 children with moderate-to-severe asthma from VOYAGE enrolled in EXCURSION, a 52 week, open-label extension study conducted at 70 centres across 17 countries. 240 children continued with add-on dupilumab (dosed according to bodyweight: 100 mg for those weighing ≤30 kg and 200 mg for those weighing more than 30 kg at EXCURSION baseline) once every 2 weeks administered by subcutaneous injection (dupilumab/dupilumab group) and 125 children on placebo during VOYAGE initiated dupilumab (100 or 200 mg, according to bodyweight), once every 2 weeks administered by subcutaneous injection (placebo/dupilumab group). Following a protocol amendment, for a subset of children weighing 30 kg or less, the dose was changed to 300 mg once every 4 weeks. The primary endpoint for the open-label extension study was the number and proportion of patients with any treatment-emergent adverse event (TEAE) during the 52-week study period in the overall population (defined as children aged 6-11 years old with moderate-to-severe asthma who previously completed VOYAGE). Statistical analyses were descriptive. This study is registered with ClinicalTrials.gov (NCT03560466; EXCURSION). FINDINGS Children who completed VOYAGE were eligible to enrol in EXCURSION between June 21, 2018 and Aug 18, 2020. During EXCURSION, the safety profile and proportion of patients reporting TEAEs were consistent with those observed during the parent study (VOYAGE). In the overall population, 232 (63·6%) of 365 patients experienced at least one TEAE (dupilumab/dupilumab: 147 [61·3%]; placebo/dupilumab: 85 [68·0%]). The most frequently reported TEAEs were nasopharyngitis, pharyngitis, and upper respiratory tract infections. INTERPRETATION In EXCURSION, long-term treatment with dupilumab was well tolerated with an acceptable safety profile. FUNDING Sanofi and Regeneron Pharmaceuticals.

Abstract
BACKGROUND Latent tuberculosis infection (LTBI) is defined as an immune response to Mycobacterium tuberculosis infection that does not manifest clinically as active tuberculosis (TB). Since some immunotherapies can alter cellular immunity, LTBI screening has been recommended for patients with multiple sclerosis (pwMS) before initiation of long-term immunotherapies. In this study, we investigated the frequency of LTBI in Korean pwMS and patients with neuromyelitis optica spectrum disorder (pwNMOSD) and reported the long-term observation of untreated LTBI under various immunotherapies. METHODS We enrolled pwMS or pwNMOSD who visited the Neurology department of the National Cancer Center between 2017 and 2021. LTBI was determined based on positive results of interferon-gamma release assay (IGRA) using QuantiFERON Gold Plus test and no evidence of active TB. Annual chest X-ray and careful monitoring for TB symptoms were performed until April 2023 or the time of follow-up loss. RESULTS Among 531 patients who underwent the IGRA test, 25 pwMS (10.5%) and 42 pwNMOSD (14.3%) were diagnosed with LTBI. Of the 67 patients with LTBI, 59 patients (24 pwMS and 35 pwNMOSD) declined to receive preventive anti-TB drugs. None of the 59 with untreated LTBI demonstrated TB reactivation during 74.8 person-years in pwMS and 166.1 person-years in pwNMOSD. In addition, eight patients who completed the treatment for LTBI experienced no TB reactivation for a median of 5.5 years. CONCLUSION The LTBI prevalence in Korean pw MS and pwNMOSD was 10.5% and 14.3%, respectively, which was much higher than that in pwMS from Western countries. Notably, none of the 59 patients with untreated LTBI showed TB reactivation over 240 person-years even under long-term immunotherapies, indicating the need for additional research to stratify the risk of LTBI-reactivation.

Abstract
The immunocompromised host is at an increased risk for pulmonary and extrapulmonary NTM infections. Where data are available in these specific populations, increased mortality is observed with NTM disease. Prior to starting therapy for NTM disease, providers should ensure diagnostic criteria are met as treatment is long and often associated with significant side effects and toxicities. Treatment should involve 2 to 4 agents and be guided by cultures and antimicrobial susceptibilities. Drug interactions are important to consider, especially in those with HIV or transplant recipients. Whenever possible, immunosuppression should be reduced or changed.

Am J Kidney Dis 2023; 82:725-736. [PMID: 37516296 DOI: 10.1053/j.ajkd.2023.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 04/16/2023] [Accepted: 05/18/2023] [Indexed: 07/31/2023]
Abstract
RATIONALE & OBJECTIVE Kidney failure is an established risk factor for active tuberculosis (TB) but the risk of TB has not been reported in specific kidney diseases. We sought to determine the incidence of and risk factors for active TB in patients with glomerular disease. STUDY DESIGN Observational cohort study. SETTING & PARTICIPANTS A provincial kidney pathology registry (2000-2012) was used to identify 3,079 adult patients with IgA nephropathy, focal segmental glomerulosclerosis (FSGS), antineutrophil cytoplasmic antibody (ANCA)-related glomerulonephritis, lupus nephritis, membranous nephropathy, minimal change disease, or "other" glomerular diseases in British Columbia, Canada. EXPOSURE Predictors included demographics, immigration status, comorbidities, immunosuppression use, estimated glomerular filtration rate (eGFR), and proteinuria. OUTCOME A diagnosis of active TB was ascertained using administrative data linkages and defined based on (1) the dispensation of 1 or more unique combinations of medications used to treat active TB, or (2) physician or hospital visits for active TB. ANALYTICAL APPROACH The definition of TB was validated in an external cohort linked to the Provincial TB registry at the BC Centre for Disease Control (BCCDC). Standardized incidence ratios were calculated using the age-matched general population. Risk factors for active TB were identified using Cox proportional hazards regression analysis. RESULTS The sensitivity and specificity of the outcome definition of active TB were 87.6% and 99.5%, respectively. During a median follow-up of 6.2 years, 41 patients developed active TB with an incidence of 197 of 100,000 person-years, approximately 23 times as high as the general population and>6 times higher than the threshold of 30 per 100,000 used to define high TB incidence. A high incidence was observed in all glomerular diseases (range, 110-403 per 100,000), in both Canadian- and foreign-born patients (range, 124-424 per 100,000), and in patients exposed or not to immunosuppression (282 vs 147 per 100,000). Factors associated with higher TB risk included immigration from a high-incidence country (HR, 3.90 [95% CI, 1.75-8.68]), diminished eGFR (HR, 2.81 [95% CI, 1.18-6.69]), higher levels of proteinuria (HR, 1.15 [95% CI, 1.04-1.27]), lupus nephritis (HR, 2.79 [95% CI, 1.37-5.68]), and immunosuppression use (HR, 2.13 [95% CI, 1.13-4.03]). LIMITATIONS A relatively low number of events contributed to uncertainty in risk estimates. CONCLUSIONS Patients with glomerular disease have a high incidence of active TB irrespective of disease type, demographics, or use of immunosuppression. Prospective studies are needed to evaluate the utility of screening for latent TB infection in this population. PLAIN-LANGUAGE SUMMARY Patients with kidney failure are at high risk of developing tuberculosis (TB), a major infection that can be prevented by identifying and treating patients who have had prior exposure to TB. The risk of TB in specific kidney diseases is unknown. In this Canadian study of 3,079 patients with glomerular disease, a group of autoimmune kidney conditions, the rate of TB was 23 times higher than in the general population. The rate was high irrespective of the use of immunosuppressive drugs or whether patients had immigrated to Canada from another country. These findings suggest that screening patients with glomerular disease for prior TB exposure may be beneficial; however, this needs to be evaluated in a prospective study.

Abstract
Neuromyelitis Optica Spectrum Disorder (NMOSD) is an inflammatory autoimmune disorder of the central nervous system, with optic neuritis and transverse myelitis as its most common presentations. Although immunomodulatory treatment options for NMOSD have expanded, preventing reactivation of latent infections in patients can be both a therapeutic challenge and a special consideration for the neurohospitalist in an inpatient setting. We present a challenging case of a NMOSD patient who presented to the emergency department with worsening weakness and numbness in the setting of an NMOSD pseudo-relapse, later found to have untreated latent tuberculosis (TB) and chronic hepatitis B (HBV). She was briefly treated with high-dose IV methylprednisolone, which was stopped after her symptoms and imaging became more consistent with a pseudo-relapse. After confirmation that neither HBV nor TB had reactivated, the patient was discharged on isoniazid and entecavir. A month later, the patient's symptoms were stable, and she was started on inebilizumab for relapse prevention of NMOSD. This case report is the first to highlight the therapeutic complexities of managing NMOSD that requires immunosuppression in the setting of preventing reactivation of both TB and HBV.

Abstract
In this study, we conducted a comprehensive assessment of the cytotoxicity of three glucocorticoids, namely Hydrocortisone, Dexamethasone, and Methylprednisolone, using three different human cell lines: MDA-MB-231, MCF-7 (both adenocarcinoma cell lines), and HEK293 (kidney epithelial cell line). At lower concentrations exceeding 50 µM, we did not observe any significant toxic effects of these glucocorticoids. However, when exposed to higher concentrations, Hydrocortisone exhibited dose-dependent cytotoxic effects on all three cell lines, with calculated IC50 values of 12 ± 0.6 mM for HEK293, 2.11 ± 0.05 mM for MDA-MB-231, and 2.73 ± 0.128 mM for MCF-7 cells after 48 h of exposure. Notably, Hydrocortisone, at its respective IC50 concentrations, demonstrated an inhibitory effect on the proliferation of the cancer cell lines, as evidenced by a substantial reduction in BrdU absorbance in a dose-dependent manner, coupled with a markedly reduced rate of colony formation in treated cells. Furthermore, Hydrocortisone exhibited remarkable anti-migratory properties in MDA-MB-231 and MCF-7 cells, and it induced cell cycle arrest in the SubG1 phase in MDA-MB-231 cells. In addition to these effects, Hydrocortisone triggered apoptosis in both cancer cell types, leading to observable morphological changes. This apoptotic response was characterized by a significant increase in the activity of caspase-3, which was time-dependent. Additionally, Hydrocortisone downregulated the expression of anti-apoptotic Bcl-2 proteins. In summary, our findings underscore the safety of clinical doses in terms of cell toxicity meanwhile increased concentration were showing an anti-proliferative potential of Hydrocortisone, particularly against adenocarcinoma breast cancer cell lines.

Abstract
Paralytic ileus as tuberculosis-immune reconstitution inflammatory syndrome (TB-IRIS) is extremely rare. We herein report a 44-year-old man with pulmonary and renal tuberculosis who developed paralytic ileus 14 days after starting antituberculosis therapy (ATT) despite an initial favorable response to ATT. Paralytic ileus was successfully managed with conservative care. He initially required hemodialysis because of obstructive uropathy due to renal tuberculosis, but he was able to withdraw from dialysis after placement of ureteral stents. TB-IRIS can affect organs other than the original sites of tuberculosis, and the combined use of steroids may be effective for its prevention and treatment.

Abstract
Purpose To explore the lessons learned from the misdiagnosis of systemic lupus erythematosus (SLE) combined with urinary tuberculosis leading to tuberculous meningitis (TBM) and the diagnosis and treatment of TBM through case reports and review of the literature. Methods We report a case of an SLE patient presenting with urinary tuberculosis infection misdiagnosed as interstitial cystitis and complex urinary tract infection, who developed neurological infection after a cystocentesis biopsy and was eventually diagnosed with TBM. In addition, all cases of SLE combined with TBM from January 1975 to February 2022 were summarised and reviewed to compare current diagnostic and treatment strategies for the disease. Results The patient suddenly developed neurological symptoms after cystocentesis biopsy, and we detected Mycobacterium tuberculosis in the macrogenomic next-generation sequence (mNGS) of the cerebrospinal fluid. We therefore excluded interstitial cystitis and neuropsychiatric lupus to confirm the diagnosis of Mycobacterium tuberculosis infection leading to urinary tract tuberculosis and TBM. Conclusion SLE is complicated by urological tuberculosis, surgery triggering hematogenous dissemination leading to tuberculous meningitis. At the same time, the lack of specificity in the clinical presentation of patients makes it easy to misdiagnose neuropsychiatric lupus and delay treatment, so timely and accurate diagnosis and effective anti-tuberculosis treatment are essential.

Abstract
Tuberculosis is a disease with a significant global burden in terms of morbidity and mortality. It usually presents as a pulmonary disease but can occasionally have extrapulmonary presentations. Immunosuppressed people are at an increased risk of tuberculosis and more frequently have atypical manifestations of the disease. Cutaneous involvement is estimated to occur in only 2% of extrapulmonary presentations. We report a case of a heart transplant recipient with disseminated tuberculosis who initially presented with cutaneous manifestations in the form of multiple abscesses that were mistaken for a community-acquired bacterial infection. The diagnosis was made after positive nucleic acid amplification testing and cultures for Mycobacterium tuberculosis from the drainage of the abscesses. After initiating antituberculous treatment, the patient had 2 instances of immune reconstitution inflammatory syndrome. A combination of diminished immunosuppression due to discontinuation of mycophenolate mofetil in the setting of acute infection, rifampin drug interactions with cyclosporine, and the beginning of treatment of tuberculosis all contributed to this paradoxical worsening. The patient responded favorably to increased glucocorticoid therapy and showed no signs of treatment failure after 6 months of antituberculous therapy.

Abstract
Tubercular uveitis (TB-uveitis) remains a conundrum in the uveitis field, which is mainly related to the diverse clinical phenotypes of TB-uveitis. Moreover, it remains difficult to differentiate whether Mycobacterium tuberculosis (Mtb) is present in the ocular tissues, elicits a heightened immune response without Mtb invasion in ocular tissues, or even induces an anti-retinal autoimmune response. Gaps in the immuno-pathological knowledge of TB-uveitis likely delay timely diagnosis and appropriate management. In the last decade, the immunopathophysiology of TB-uveitis and its clinical management, including experts' consensus to treat or not to treat certain conditions with anti-tubercular treatment (ATT), have been extensively investigated. In the meantime, research on TB treatment, in general, is shifting more toward host-directed therapies (HDT). Given the complexities of the host-Mtb interaction, enhancement of the host immune response is expected to boost the effectiveness of ATT and help overcome the rising burden of drug-resistant Mtb strains in the population. This review will summarize the current knowledge on the immunopathophysiology of TB-uveitis and recent advances in treatment modalities and outcomes of TB-uveitis, capturing results gathered from high- and low-burden TB countries with ATT as the mainstay of treatment. Moreover, we outline the recent progress of HDT development in the pulmonary TB field and discuss the possibility of its applicability to TB-uveitis. The concept of HDT might help direct future development of efficacious therapy for TB-uveitis, although more in-depth research on the immunoregulation of this disease is still necessary.

[PMID: 37274816 PMCID: PMC10232946 DOI: 10.3389/fped.2023.1162547] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Accepted: 04/13/2023] [Indexed: 06/07/2023] Open
Abstract
Objective We aimed to compare QuantiFERON-TB Gold In-Tube (QFT-GIT) and X.DOT-TB for screening latent tuberculosis infection (LTBI) in kawasaki patients, and to identify the risk factors associated with indeterminate IGRA results. Methods We conducted a retrospective study on children with KD, who were screened for mycobacterium tuberculosis (Mtb) infection by either ELISA-based QFT-GIT or ELISPOT-based X.DOT-TB tests, admitted in Department of Cardiology, Beijing Children's Hospital from July 2019 to April 2022. Results A total of 1327 cases were included. Among them, 932 cases were tested by QFT-GIT and 395 cases by X.DOT-TB. The positive rate of children was 0.1% and 0.2%, and the indeterminate rate was 68.2% and 6.1% for QFT-GIT and X.DOT-TB, respectively. Patients with hypoproteinemia had a higher risk of indeterminate X.DOT-TB result. Female, critical ill, shock or hypoproteinemia presented statistically significant associations with an increased risk of indeterminate QFT-GIT result. High-dose of IVIG inhibited the release of IFN-γ by more than 90%, which might account for the high indeterminate incidence. Conclusion It is recommended to perform X.DOT-TB rather than QFT-GIT to screen LTBI in patients with high level of the mitogen that can inhibit IFN-γ release. For KD children with positive IGRA results, it has a higher risk of activation TB infection when treated with immunosuppressive therapy in the future. Children with KD aged <5 years old had higher frequency of indeterminate IGRA results.

Abstract
A 19-year-old woman originally from the Republic of the Marshall Islands presented with diffuse pneumonia and acute hypoxemic respiratory failure. She dies one month into her hospitalization but the diagnosis of pulmonary tuberculosis (TB) was not made until one day before her demise. A contact investigation screened a total of 155 persons with 36 (23%) found to have latent TB infection and seven (4.5%) with active pulmonary TB. This unfortunate case provided the opportunity to analyze the epidemiology of TB in the state of Washington in the context of those who emigrated from the Marshall Islands. The development of fulminant pulmonary TB in this previously healthy young woman also provides a segue to discuss potential risk factors for TB in the index case that include: (i) foreign-born in a TB-endemic country; (ii) race and genetic factors; (iii) age; (iv) body habitus; (v) pregnancy; and (vi) use of glucocorticoids.

Abstract
We do not yet understand exactly how corticosteroids attenuate hyperinflammatory responses and alleviate high-risk coronavirus disease 2019 (COVID-19). We aimed to reveal the molecular mechanisms of hyperinflammation in COVID-19 and the anti-inflammatory effects of corticosteroids in patients with high-risk COVID-19. We performed single-cell RNA sequencing of peripheral blood mononuclear cells (PBMCs) from three independent COVID-19 cohorts: cohort 1 was used for comparative analysis of high-risk and low-risk COVID-19 (47 PBMC samples from 28 patients), cohort 2 for longitudinal analysis during COVID-19 (57 PBMC samples from 15 patients), and cohort 3 for investigating the effects of corticosteroid treatment in patients with high-risk COVID-19 (55 PBMC samples from 13 patients). PBMC samples from healthy donors (12 PBMC samples from 12 donors) were also included. Cohort 1 revealed a significant increase in the proportion of monocytes expressing the long noncoding RNAs NEAT1 and MALAT1 in high-risk patients. Cohort 2 showed that genes encoding inflammatory chemokines and their receptors were upregulated during aggravation, whereas genes related to angiogenesis were upregulated during improvement. Cohort 3 demonstrated downregulation of interferon-stimulated genes (ISGs), including STAT1, in monocytes after corticosteroid treatment. In particular, unphosphorylated STAT-dependent ISGs enriched in monocytes from lupus patients were selectively downregulated by corticosteroid treatment in patients with high-risk COVID-19. Corticosteroid treatment suppresses pathologic interferon responses in monocytes by downregulating STAT1 in patients with high-risk COVID-19. Our study provides insights into the mechanisms underlying COVID-19 aggravation and improvement and the effects of corticosteroid treatment.

Methylprednisolone Promotes Mycobacterium smegmatis Survival in Macrophages through NF-κB/DUSP1 Pathway. Microorganisms 2023; 11:microorganisms11030768. [PMID: 36985341 PMCID: PMC10058212 DOI: 10.3390/microorganisms11030768] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 03/13/2023] [Accepted: 03/16/2023] [Indexed: 03/19/2023] Open
Abstract
Background: Mycobacterium tuberculosis (M. tuberculosis) is the causative agent of tuberculosis. As an important component of host immunity, macrophages are not only the first line of defense against M. tuberculosis but also the parasitic site of M. tuberculosis in the host. Glucocorticoids can cause immunosuppression, which is considered to be one of the major risk factors for active tuberculosis, but the mechanism is unclear. Objective: To study the effect of methylprednisolone on the proliferation of mycobacteria in macrophages and try to find key molecules of this phenomenon. Methods: The macrophage line RAW264.7 infected by M. smegmatis was treated with methylprednisolone, and the intracellular bacterial CFU, Reactive Oxygen Species (ROS), cytokine secretion, autophagy, and apoptosis were measured. After the cells were treated with NF-κB inhibitor BAY 11-7082 and DUSP1 inhibitor BCI, respectively, the intracellular bacterial CFU, ROS, IL-6, and TNF-α secretion were detected. Results: After treatment with methylprednisolone, the CFU of intracellular bacteria increased, the level of ROS decreased, and the secretion of IL-6 and TNF-α decreased in infected macrophages. After BAY 11-7082 treatment, the CFU of M. smegmatis in macrophages increased, and the level of ROS production and the secretion of IL-6 by macrophages decreased. Transcriptome high-throughput sequencing and bioinformatics analysis suggested that DUSP1 was the key molecule in the above phenomenon. Western blot analysis confirmed that the expression level of DUSP1 was increased in the infected macrophages treated with methylprednisolone and BAY 11-7082, respectively. After BCI treatment, the level of ROS produced by infected macrophages increased, and the secretion of IL-6 increased. After the treatment of BCI combined with methylprednisolone or BAY 11-7082, the level of ROS produced and the secretion of IL-6 by macrophages were increased. Conclusion: methylprednisolone promotes the proliferation of mycobacteria in macrophages by suppressing cellular ROS production and IL-6 secretion through down-regulating NF-κB and up-regulating DUSP1 expression. BCI, an inhibitor of DUSP1, can reduce the level of DUSP1 in the infected macrophages and inhibit the proliferation of intracellular mycobacteria by promoting cellular ROS production and IL-6 secretion. Therefore, BCI may become a new molecule for host-directed therapy of tuberculosis, as well as a new strategy for the prevention of tuberculosis when treated with glucocorticoids.

Abstract
There are about 200 different types of interstitial lung disease (ILD), and a crucial initial step in the assessment of a patient with suspected ILD is achieving an appropriate diagnosis. Some ILDs respond to immunosuppressive agents, while immunosuppression can be detrimental in others, hence treatment is based on the most confident diagnosis with consideration of a patient's risk factors. Immunosuppressive medications have the potential to result in substantial, and perhaps life-threatening, bacterial infections to a patient. However, data on the risk of bacterial infections from immunosuppressive treatment specifically in patients with interstitial lung disease is lacking. We hereby review the immunosuppressive treatments used in ILD patients excluding sarcoidosis, highlight their risk of bacterial infections, and discuss the potential mechanisms that contribute to the increased risk of infections.

Abstract
Objective To explore the clinical characteristics and risk factors of common systemic rheumatism concomitant with tuberculosis (TB). Methods A total of 3,906 patients of RA, SLE, and SS diagnosed in the People's Hospital of Sichuan Province from January 2007 to January 2017 were collected. One hundred and five patients with TB were included as TB group, including 42 RA, 41 SLE, and 22 SS patients. In the non-TB group, 84 RA, 82 SLE, and 44 SS patients were randomly selected during the same period. Results Fever was the most common symptom among RA, SLE, and SS patients with TB, accounting for 83.3%, 92.7%, and 68.2%, respectively. Cough, weight loss or fatigue were the next common. RA patients with TB were mostly pulmonary TB (PTB), accounting for 64.3%. The proportion of PTB for SLE and SS were 46.3%, 59.01%, respectively. In TB group, 59% RA, 57% SLE, and 62% SS with PTB had two or more chest CT findings. There were 48 TB cases received both Interferon Gamma Release Assay (IGRA) and Tuberculin skin test (TST) with positive rates of 91.8%, 45.8%, respectively. The daily average dose of glucocorticoids within 1 year in TB group was higher than that in non-TB group of SLE patients, lower counts of CD4+ T cell count were found in TB group (P < 0.05), while no such differences were found in RA and SS patients. Conclusion RA patients with TB are mainly pulmonary TB. For SLE and SS patients, the chance of PTB and extrapulmonary tuberculosis is similar. Daily average dose of glucocorticoids within 1 year may be a common risk factor for RA, SLE and SS patients developing TB. Decreased CD4+ T cell count may also be a risk factor for SLE patients with TB. Symptoms of RA, SLE, SS with TB, are similar with the primary disease or other infection. It is recommended to conduct both TST and IGRA to help diagnose TB.

Abstract
Biologic medications have dramatically improved the treatment outcomes of immunological inflammatory diseases, but their immunosuppressive effects put patients at risk for tuberculosis (TB). We investigated the risk factors for developing TB in patients treated for latent tuberculosis infection (LTBI) who also had experience of using biologic medications. At Keio University Hospital, we retrospectively investigated patients treated with anti-mycobacterial drugs before or concurrently with biologic medications from January 2012 to August 2020. Patients in the 'follow-on cases group' who had a positive TB screening test after initiating biologic medications and subsequently started LTBI treatment were excluded. We researched and compared the patient characteristics for TB and non-TB patient groups. Of the 146 eligible patients, 5 (3.4%) developed TB. The incidence rate was 600/100000 person-years. There were no significant differences between TB and non-TB patient groups in the history of TB, interferon-gamma release assay (IGRA), duration of biologic medication therapy, LTBI treatment periods, concomitant use of calcineurin inhibitors or anti-rheumatic drugs. The percentage of patients who received prednisolone at a dose of ≥15 mg for more than 1 month was higher in those who developed TB than in those who did not (40.0 vs. 7.1%, p = 0.054); however, this difference was not statistically significant. Regular monitoring of TB is necessary for long-term concomitant use of high prednisolone doses during and after the administration of biologic medications.

Abstract
A 39-year-old woman presented with cushingoid features was worked up and diagnosed to have ACTH-independent Cushing's syndrome. Computed tomography of the whole abdomen revealed a left adrenal mass. She was scheduled for elective laparoscopic left adrenalectomy, however, a few days prior to the surgery, the patient had hematochezia. Colonoscopy revealed multiple ulcers on the terminal ileum, to which biopsy revealed Mycobacterium tuberculosis infection. The patient underwent laparoscopic left adrenalectomy on the same admission, which revealed adrenal adenoma on histopathology.

Abstract
Nous rapportons deux cas de réactivation tuberculeuse après COVID-19 sous corticostéroïdes et tocilizumab. Ils ont présenté une lymphopénie, des signes cliniques limités, des signes radiologiques inhabituels mais des prélèvements microbiologiques positifs. Le dépistage de l'infection tuberculeuse latente (ITL) étant inapproprié dans ce contexte, il faudrait discuter de la traiter systématiquement chez des patients les plus à risque en cas de traitement immunomodulateur.

Abstract
Relevance to Patient Care and Clinical Practice: Corticosteroids are among the most prescribed medications, particularly during the COVID-19 era. The literature has clearly highlighted the dangers of prolonged, high-dose corticosteroid use, which is important for clinicians to consider before treating patients in their clinical practices. Objective: The objective of this article is to review the literature on complications of corticosteroid use, review corticosteroid pharmacokinetics, and provide an updated reference on risks associated with corticosteroid therapy, especially at higher doses. Data Sources: A conventional literature search of PubMed was conducted without restrictions on publication date. Search terms included "corticosteroids," "avascular necrosis," "gastrointestinal bleeding," and "complications." Study Selection and Data Extraction: Pertinent systematic review/meta-analyses and randomized controlled trials were reviewed for study inclusion. Data Synthesis: Corticosteroids were associated with complications including avascular necrosis, gastrointestinal bleeding, myocardial infarction, heart failure, cerebrovascular events, diabetes mellitus, psychiatric syndromes, ophthalmic complications, tuberculosis reactivation, and bacterial sepsis. Increased daily and cumulative doses were associated with increased excess risk of complications. Cumulative doses greater than 430 mg prednisone equivalent were shown to increase the excess risk of avascular necrosis, with progressively higher rates with higher doses. Risk of gastrointestinal bleeding was significantly increased with corticosteroid usage in the in-patient but not out-patient setting. Conclusion: Since corticosteroids have been associated with the aforementioned severe complications and frequent medicolegal malpractice claims, counseling and informed consent should be performed when prescribing moderate-high dosages of corticosteroids. Further research is needed to characterize the long-term effects of corticosteroid usage in COVID-19 patients.

Abstract
ObjectivesTo develop EULAR recommendations for screening and prophylaxis of chronic and opportunistic infections in patients with autoimmune inflammatory rheumatic diseases (AIIRD).MethodsAn international Task Force (TF) (22 members/15 countries) formulated recommendations, supported by systematic literature review findings. Level of evidence and grade of recommendation were assigned for each recommendation. Level of agreement was provided anonymously by each TF member.ResultsFour overarching principles (OAP) and eight recommendations were developed. The OAPs highlight the need for infections to be discussed with patients and with other medical specialties, in accordance with national regulations. In addition to biologic/targeted synthetic disease-modifying antirheumatic drugs (DMARDs) for which screening for latent tuberculosis (TB) should be performed, screening could be considered also before conventional synthetic DMARDs, glucocorticoids and immunosuppressants. Interferon gamma release assay should be preferred over tuberculin skin test, where available. Hepatitis B (HBV) antiviral treatment should be guided by HBV status defined prior to starting antirheumatic drugs. All patients positive for hepatitis-C-RNA should be referred for antiviral treatment. Also, patients who are non-immune to varicella zoster virus should be informed about the availability of postexposure prophylaxis should they have contact with this pathogen. Prophylaxis againstPneumocystis jiroveciiseems to be beneficial in patients treated with daily doses >15–30 mg of prednisolone or equivalent for >2–4 weeks.ConclusionsThese recommendations provide guidance on the screening and prevention of chronic and opportunistic infections. Their adoption in clinical practice is recommended to standardise and optimise care to reduce the burden of opportunistic infections in people living with AIIRD.

Abstract
OBJECTIVE To conduct a systematic literature review (SLR) on the screening and prophylaxis of opportunistic and chronic infections in autoimmune inflammatory rheumatic diseases (AIIRD). METHODS SLR (inception-12/2021) based on the following search domains: (1) infectious agents, (2) AIIRD, (3) immunosuppressives/immunomodulators used in rheumatology, (4) screening terms and (5) prophylaxis terms. Articles were retrieved having the terms from (1) AND (2) AND (3) plus terms from (4) OR(5). Databases searched: PubMed, Embase and Cochrane Library. EXCLUSION CRITERIA studies on postoperative infections, paediatric AIIRD, COVID-19, vaccinations and non-Εnglish literature. Study quality was assessed with Newcastle-Ottawa scale for non-randomised controlled trials (RCTs), RoB-Cochrane for RCTs, AMSTAR2 for SLRs. RESULTS From 5641 studies were retrieved, 568 full-text articles were assessed for eligibility, with 194 articles finally included. For tuberculosis, tuberculin skin test (TST) is affected by treatment with glucocorticoids and conventional synthetic disease modifying anti-rheumatic drugs (DMARDs) and its performance is inferior to interferon gamma release assay (IGRA). Agreement between TST and IGRA is moderate to low. For hepatitis B virus (HBV): risk of reactivation is increased in patients positive for hepatitis B surface antigen. Anti-HBcore positive patients are at low risk for reactivation but should be monitored periodically with liver function tests and/or HBV-viral load. Risk for Hepatitis C reactivation is existing but low in patients treated with biological DMARDs. For Pneumocystis jirovecii, prophylaxis treatment should be considered in patients treated with prednisolone ≥15-30 mg/day for >2-4 weeks. CONCLUSIONS Different screening and prophylaxis approaches are described in the literature, partly determined by individual patient and disease characteristics.

Abstract
α1-Antitrypsin (AAT), a serine protease inhibitor, is the third most abundant protein in plasma. Although the best-known function of AAT is irreversible inhibition of elastase, AAT is an acute-phase reactant and is increasingly recognized to have a panoply of other functions, including as an anti-inflammatory mediator and a host-protective molecule against various pathogens. Although a canonical receptor for AAT has not been identified, AAT can be internalized into the cytoplasm and is known to affect gene regulation. Because AAT has anti-inflammatory properties, we examined whether AAT binds the cytoplasmic glucocorticoid receptor (GR) in human macrophages. We report the finding that AAT binds to GR using several approaches, including coimmunoprecipitation, mass spectrometry, and microscale thermophoresis. We also performed in silico molecular modeling and found that binding between AAT and GR has a plausible stereochemical basis. The significance of this interaction in macrophages is evinced by AAT inhibition of LPS-induced NF-κB activation and IL-8 production as well as AAT induction of angiopoietin-like 4 protein, which are, in part, dependent on GR. Furthermore, this AAT-GR interaction contributes to a host-protective role against mycobacteria in macrophages. In summary, this study identifies a new mechanism for the gene regulation, anti-inflammatory, and host-defense properties of AAT.

Lancet Gastroenterol Hepatol 2022; 7:962-972.

Abstract
Inflammatory bowel disease (IBD) is generally considered a disease of high-income countries and is regarded as rare in sub-Saharan Africa. However, this assumption is almost certainly an underestimate, and the high burden of communicable diseases makes IBD in sub-Saharan Africa difficult to detect. Furthermore, some gastrointestinal infections can closely mimic IBD, contributing to delays in diagnosis and complicating therapeutic decision making. Constraints in endoscopic capacity alongside a scarcity of qualified diagnostic pathologists add to the difficulties. Implementing evidence-based guidelines recommended by international societies is challenging, mostly due to high costs and unavailability of medication. However, cost-effective approaches can still be implemented to manage IBD in sub-Saharan Africa as the predominant disease phenotype is mild-to-moderate ulcerative colitis, which often responds to treatment with basic medication. In this Series paper, we summarise the current management of IBD in sub-Saharan Africa and propose how it can be tailored to suit the epidemiological and socioeconomic specificities of the region. We also discuss measures required to address existing challenges, such as educating health-care workers about the diagnosis and management of IBD or improving endoscopic capacity.

Abstract
Abstract
Background
Tuberculosis is routinely encountered on imaging throughout the world. Radiologists are usually familiar with the common patterns of tuberculosis on cross-sectional imaging. However, tuberculosis frequently presents with unfamiliar imaging patterns and/or uncommon anatomic sites which still pose a diagnostic challenge.
Discussion
Rapid improvements in the management of acquired immunodeficiency syndrome patients leading to increased survival as well as advances in chemotherapy and immunosuppressive medication have complicated the presentation of tuberculosis by increasing the probability of unconventional sites and patterns of involvement in tuberculosis leading to unfamiliar imaging appearances. In this review, we describe these unfamiliar imaging patterns of tuberculosis and provide a diagnostic protocol for arriving at the right diagnosis and differentiating these from other pathologies with similar imaging appearances. These are described through case-based illustrations of unusual patterns and anatomic locations of tuberculosis.
Conclusions
It is important for radiologists to be aware of such unusual imaging patterns of tuberculosis in order to facilitate early and accurate diagnosis for appropriate patient management in the face of changing patient demographics and pathological profile of tuberculosis in the current era of scientific advancements.

Abstract
ALSUntangled reviews alternative and off-label treatments for people with amyotrophic lateral sclerosis (PALS). Here we review glucocorticoids. Neuroinflammation plays a prominent role in amyotrophic lateral sclerosis (ALS) pathogenesis, so some hypothesize that glucocorticoids might be an effective ALS therapy through their immunosuppressive effects. In this paper, we review the available evidence for glucocorticoids in ALS, including one pre-clinical study with a genetic mouse model of ALS, nine case reports (ranging from 1 to 26 patients each), and four clinical trials. We also review the possible side effects (including steroid myopathy) and the costs of therapy. We graded the level of evidence as follows: Mechanism, D; Pre-Clinical, F; Cases, B; Trials, F; Risks, C. Our review of the current evidence concludes that glucocorticoids do not offer clinical benefit in ALS and confer serious risks. Thus, ALSUntangled does not recommend glucocorticoids as a treatment for ALS.

Abstract
In mid-2014, Public Health Ontario Laboratories identified coincident increasing Mycobacterium avium isolation and falling M. xenopi isolation in the Toronto, Ontario, Canada, area. We performed a retrospective cohort of all patients in a Toronto clinic who began treatment for either M. avium or M. xenopi pulmonary disease during 2009–2012 (early period) or 2015–2018 (late period), studying their relative proportions and sputum culture conversion. We conducted a subgroup analysis among patients who lived in the Toronto-York region. The proportion of patients with M. avium was higher in the late period (138/146 [94.5%] vs. 82/106 [77.4%]; p<0.001). Among M. avium patients, conversion was lower in the late period (26.1% vs. 39.0%; p = 0.05). The increase in the proportion of patients with M. avium pulmonary disease and the reduction in the frequency of sputum culture conversion is unexplained but could suggest an increase in environmental M. avium exposure.

Abstract
Managing pediatric tuberculosis (TB) remains a public health problem requiring urgent and long-lasting solutions as TB is one of the top ten causes of ill health and death in children as well as adolescents universally. Minors are particularly susceptible to this severe illness that can be fatal post-infection or even serve as reservoirs for future disease outbreaks. However, pediatric TB is the least prioritized in most health programs and optimal infection/disease control has been quite neglected for this specialized patient category, as most scientific and clinical research efforts focus on developing novel management strategies for adults. Moreover, the ongoing coronavirus pandemic has meaningfully hindered the gains and progress achieved with TB prophylaxis, therapy, diagnosis, and global eradication goals for all affected persons of varying age bands. Thus, the opening of novel research activities and opportunities that can provide more insight and create new knowledge specifically geared towards managing TB disease in this specialized group will significantly improve their well-being and longevity.

Abstract
Background Systemic lupus erythematosus (SLE) patients are particularly susceptible to infections, such as pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB). This meta-analysis aimed to determine the incidence and prevalence of tuberculosis (TB) in SLE patients. Methods The Web of Science, PubMed, Cochrane Library, and Chinese National Knowledge Infrastructure databases were searched for articles of relevant studies published from the dates the databases were established until April 30, 2022. The I2 statistic and Q test were used to evaluate heterogeneity among the analysed studies. Random-effects models were utilised and subgroup analyses were conducted for analysis of the study data. Results A total of 35 studies with 46,327 SLE patients were eligible for analysis. The incidence and prevalence of TB among the SLE patients were 1.16 per 100 person-years (95% confidence interval (CI): 0.69-1.93) and 3.59% (95% CI: 2.57%-5.02%), respectively. The pooled prevalence of SLE-PTB and SLE-EPTB was 2.46% (95% CI: 1.73%-3.51%) and 1.42% (95% CI: 0.98%-2.06%), respectively. Subgroup analyses showed that the incidence of SLE-TB was higher in Africa and in countries with a high TB burden than in countries with a low TB burden. The prevalence of SLE-TB was elevated in Asia, in patients taking a mean daily dose of glucocorticoids ≥20 mg, in studies with small sample sizes (n <1000) and ended before 2001. Conclusions The available evidence suggests that both the incidence and prevalence of TB in SLE patients are high. This study provides a more specific understanding of SLE-TB, which can help health policymakers in the development of preventive strategies for reducing the SLE-TB burden.

Front Med (Lausanne) 2022; 9:875910. [PMID: 35911382 PMCID: PMC9334667 DOI: 10.3389/fmed.2022.875910] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Accepted: 06/27/2022] [Indexed: 12/24/2022] Open
Abstract
We reviewed the available information on the use of immune checkpoint inhibitors (ICIs) in populations with special conditions, namely, patients with HIV, tuberculosis, or underlying autoimmune disease. Available data show that treatment with ICIs is safe in patients with HIV; it is advisable, however, that these patients receive adequate antiretroviral therapy and have an undetectable viral load before ICIs are initiated. Tuberculosis reactivation has been reported with the use of ICIs, possibly due to immune dysregulation. Tuberculosis has also been associated with the use of immunosuppressors to treat immune-related adverse events (irAEs). Active tuberculosis must be ruled out in patients with symptoms or signs, and selected patients may benefit from screening for latent tuberculosis infection, although more data are required. Limited data exist regarding the safety of ICIs in patients with cancer and autoimmune disease. Data from observational studies suggest that up to 29% of patients with a preexisting autoimmune disease treated with an ICI present with an autoimmune disease flare, and 30% present with a de novo irAE of any type. The frequency of flares appears to differ according to the type of ICI received, with higher rates associated with PD-1/PD-L1 inhibitors. The most common autoimmune diseases for which patients reported flares with ICI therapy are rheumatoid arthritis, other inflammatory arthritis, and psoriasis. Most studies have reported flares or de novo irAEs associated with ICIs that were mild to moderate, with low rates of discontinuation and no deaths due to flares. Therefore, the use of ICIs in these patients is possible, but careful monitoring is required.

Abstract
Background Coinfection with Pneumocystis jirovecii and Mycobacterium tuberculosis is rare in HIV-seronegative patients. Because it is associated with unknown morbidity and a high mortality rate especially in patients with immunosuppression, health care practitioners should have a high index of suspicion when dealing with such patients. Case Presentation A 66-year-old man with glucocorticoid therapy for 9 years had a fever after getting a cold and developed respiratory failure rapidly within 3 days. He was given trimethoprim-sulfamethoxazole empirically before Pneumocystis pneumonia (PCP) was confirmed with the presence of cysts in the sputum. Although there was a partial improvement of symptoms, an area of consolidation on the left upper lung lobe gradually enlarged. Bronchoscopy was performed 3 times and Mycobacterium tuberculosis infection was finally diagnosed. For 1 years, he was treated with standard antituberculosis agents, and his psychological well-being was managed using traditional Chinese medicine techniques. After 3 years of follow-up, his outcome was very good. Conclusion HIV-seronegative patients on long-term glucocorticoid therapy in areas with a high incidence of Mycobacterium tuberculosis may be co-infected with Pneumocystis jirovecii. When opportunistic infections are suspected, diagnostic procedures including invasive ones should be performed as soon as possible and appropriate interventions need to be carried out promptly.

Abstract
BACKGROUND One quarter of the world's population has latent tuberculosis infection (LTBI). Systemic immunosuppression is a risk factor for LTBI reactivation and the development of active tuberculosis. Such reactivation carries a risk of significant morbidity and mortality. Despite the increasing global incidence of inflammatory bowel disease (IBD) and the use of immune-based therapies, current guidelines on the testing and treatment of LTBI in patients with IBD are haphazard with a paucity of evidence. AIM To review the screening, diagnostic practices and medical management of LTBI in patients with IBD. METHODS Published literature was reviewed, and recommendations for testing and treatment were synthesised by experts in both infectious diseases and IBD. RESULTS Screening for LTBI should be performed proactively and includes assessment of risk factors, an interferon-gamma releasing assay or tuberculin skin test and chest X-ray. LTBI treatment in patients with IBD is scenario-dependent, related to geographical endemicity, travel and other factors. Ideally, LTBI therapy should be used prior to immune suppression but can be applied concurrently where urgent IBD medical treatment is required. Management is best directed by a multidisciplinary team involving gastroenterologists, infectious diseases specialists and pharmacists. Ongoing surveillance is recommended during therapy. Newer LTBI therapies show promise, but medication interactions need to be considered. There are major gaps in evidence, particularly with specific newer therapeutic approaches to IBD. CONCLUSIONS Proactive screening for LTBI is essential in patients with IBD undergoing immune-suppressing therapy and several therapeutic strategies are available. Reporting of real-world experience is essential to refining current management recommendations.

Abstract
Introduction: Indonesia has the second-highest tuberculosis cases in the world, according to the global WHO tuberculosis report, amounting to approximately 10% of the world's tuberculosis cases. Systemic lupus erythematosus (SLE) patients are at an increased risk for tuberculosis infection. This research aims to analyze the association between corticosteroid pulse dose, corticosteroid cumulative dose, SLE disease duration, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score, and lupus nephritis status with the development of tuberculosis in SLE patients. Methods: This research was a matched case-control study to identify risk factors of tuberculosis infection in SLE patients. Data were taken from medical records of Cipto Mangunkusumo National General Hospital, a national tertiary hospital. Inclusion criteria were patients who meet the Systemic Lupus Erythematosus International Collaborating Clinics (SLICC) 2012 criteria of SLE in the period of 2012-2016 or patients who meet the SLICC 2012 SLE criteria and developed tuberculosis between 2012 and 2016. Statistical analyses used were bivariate analysis and correlation analysis. All statistical analyses were conducted using SPSS software (IBM Corp., Armonk, NY). All statistical analyses were defined as statistically significant when the p-value was less than 0.05. Results: A total of 48 SLE patients were included from medical records consisting of 24 SLE patients with tuberculosis infection and controls of 24 SLE patients without tuberculosis infection. In this study, it was observed that the presence of lupus nephritis (p = 0.001), administration of pulse corticosteroids (p = 0.048), high corticosteroid cumulative dose (p = 0.001), and high SLEDAI score (p = 0.003) were associated with tuberculosis infection. Correlation analysis showed that all of these variables had a weak positive correlation with tuberculosis infection in SLE patients. Conclusion: SLE patients with lupus nephritis, administration of pulse corticosteroids, high cumulative corticosteroid dose, and high SLEDAI score have a higher risk of tuberculosis infection. Clinicians and patients should be aware of these risk factors in SLE patients to prevent tuberculosis infection. Corticosteroid pulse dose should be avoided in SLE patients and if it is needed, tuberculosis prophylaxis may be considered.

Abstract
Though the COVID-19 pandemic has made international headlines since 2020, behind the scenes, tuberculosis (TB) has remained a leading cause of global mortality. According to the WHO, TB is 1 of the top 10 causes of death globally, with about one-quarter of the world’s population infected. This case report highlights a female patient who presented to the emergency department with signs and symptoms of COVID-19 and was admitted to hospital. When the patient demonstrated minimal clinical improvement after initiating treatment for COVID-19, further investigations uncovered concomitant reactivated TB. This case is helpful in underscoring the potential implications of the COVID-19 pandemic and current treatment guidelines on the global burden of TB, which could subsequently impact how practitioners approach screening and management of latent TB infection.

Abstract
Objective To characterize the prevalence of latent tuberculosis infection (LTBI) in patients with interstitial lung diseases (ILDs) requiring immunosuppression. Only 5 to 10% of individuals infected with Mycobacterium tuberculosis develop tuberculosis, and certain groups of patients have an increased risk of illness, such as the immunocompromised. Patients with ILDs are frequently treated with immunosuppressants and, therefore, might have a higher risk of developing the disease. Methods Prospective study conducted at the ILD reference center of the Federal University of Paraná from January 2019 to December 2020. The screening of LTBI was performed with the use of the tuberculin skin test (TST). Results The sample consisted of 88 patients, of whom 64.8% were women, with a mean age of 61.4 years. The most frequent diagnoses were autoimmune rheumatic disease ILD (38.6%) and hypersensitivity pneumonitis (35.2%). The most common immunosuppressant in use at the time of the TST was prednisone, either in combination with mycophenolate (19.3%) or alone (17.1%). The majority of participants had fibrotic lung disease, characterized by a reticular interstitial pattern on chest computed tomography (79.5%) and moderate to severe functional impairment (mean FVC 69.2%). A prevalence of LTBI of 9.1% (CI 95%, 2.1%-15.1%) was found, with a TST median of 13. Conclusion Patients with ILD who are treated with immunosuppressants are not commonly screened for LTBI, despite being under a greater risk of progression to active disease. This study suggests the need for a more cautious approach to these patients.

Abstract
Inhaled corticosteroids (ICS) have a central role in the management of obstructive airway diseases. Use of ICS in asthma and chronic obstructive pulmonary disease (COPD) is associated with a small but clear increase in incidence of pneumonia and tuberculosis. Since ICS use in obstructive airway diseases has beneficial effects with regard to symptoms, lung function, quality of life and exacerbations, denying the benefit of ICS solely based on this small elevated risk of pneumonias and tuberculosis is not justified. The present article attempts to elucidate mechanisms contributing to the increased risk, assesses the magnitude and risk factors of tuberculosis in patients using ICS and provides practical suggestions for practising clinicians.

Abstract
Objective The study aimed to ascertain the clinical manifestations of inflammatory arthritis accompanying tuberculosis (TB) for the differential diagnosis. Methods We retrospectively reviewed patients with active TB who presented with inflammatory arthropathy at Seoul Medical Center. Among 2,872 patients with active TB infection, 47 had inflammatory arthropathy 14 had crystal-induced arthropathy; 12, TB arthritis; 12, Poncet's disease (PD); 8, Rheumatoid arthritis (RA); and 1, septic arthritis. The clinical characteristics and laboratory and radiographic findings of each group were analyzed. Results In TB arthritis, weight-bearing joints were more commonly affected than the elbow and wrist joints. When compared to TB arthritis, PD demonstrated a significantly higher proportion of polyarthritis and involved both large and small-to-medium-sized joints. The duration of arthritis symptoms after anti-TB treatment was significantly shorter in patients with PD (56 days vs. 90 days, p=0.028). When compared to PD, RA flares during active TB infection involved only small-to-medium-sized joints rather than a mixed distribution (62.5% vs. 16.7%, p=0.035). Patients with PD more commonly had fever at onset and showed a good response to nonsteroidal anti-inflammatory drugs alone or were in remission within 3 months after anti-TB treatment. The presence of rheumatoid factor or anti-cyclic citrullinated peptide and radiographic progression after 12 months was frequently observed in patients with RA flares. Conclusion The differential diagnosis of inflammatory arthritis accompanying active tuberculosis infection is challenging. Comprehensive history taking and physical examination, synovial fluid analysis, and a high level of clinical suspicion are essential to avoid delayed diagnosis and to reduce the significant morbidity involved.

Abstract
Granulomas are the pathological hallmark of tuberculosis (TB). In individuals with latent TB infection, Mycobacterium tuberculosis cells reside within granulomas in a nonreplicating dormant state, and a portion of them will develop active TB. Little is known on the bacterial mechanisms/factors involved in this process. In this study, we found that WhiB4, an oxygen sensor and a transcription factor, plays a critical role in disease progression and reactivation of Mycobacterium marinum (M. marinum) infection in zebrafish. We show that the whiB4::Tn mutant of M. marinum caused persistent infection in adult zebrafish, which is characterized by the lower but stable bacterial loads, constant number of nonnecrotized granulomas in fewer organs, and reduced inflammation compared to those of zebrafish infected with the wild-type bacteria or the complemented strain. The mutant bacteria in zebrafish were also less responsive to antibiotic treatments. Moreover, the whiB4::Tn mutant was defective in resuscitation from hypoxia-induced dormancy and the DosR regulon was dysregulated in the mutant. Taken together, our results suggest that WhiB4 is a major driver of reactivation from persistent infection. IMPORTANCE About one-quarter of the world’s population has latent TB infection, and 5 to 10% of those individuals will fall ill with TB. Our finding suggests that WhiB4 is an attractive target for the development of novel therapeutics, which may help to prevent the reactivation of latent infection, thereby reducing the incidences of active TB.
