Latent Tuberculosis

Tuberculosis can coexist with malignancy in the same organ, but cancer with TB in the cervix is rare. This is a case of cervical tuberculosis diagnosed in a cervical cancer patient after concurrent chemoradiotherapy and brachytherapy. This is the case of a 38-year-old G2P2 (2002) diagnosed with squamous cell carcinoma, large cell non-keratinizing cervix, Stage IIIB. The patient underwent concurrent chemoradiotherapy and brachytherapy. One month after the last brachytherapy dose, the attending physician noted a nodularity on the anterior lip of the cervix. A cervical punch biopsy was done to rule out tumor persistence. The histopathology revealed chronic granulomatous inflammation with Langhan’s type multinucleated giant cells consistent with tuberculous infection. She was diagnosed with cervical tuberculosis, postulated to be from latent TB reactivation, and was given Anti-Koch’s medication for six months. After receiving Anti-Koch’s treatment, the cervical nodularity was no longer appreciated, and the rest of the cervix was smooth on palpation. Her Pap Test was negative for any intraepithelial lesion and was declared with no evidence of carcinoma. A possible latent TB infection should always be screened in cancer patients from high-burden areas or those with close contact treated for tuberculosis because immunosuppression during cancer treatment can cause the reactivation of tuberculous disease. Cervical tuberculosis complicating cervical malignancy is treatable with Anti-Koch’s therapy and has not been shown to affect the course of the carcinoma.

Background: Tuberculosis remains to be a major cause of morbidity in children and treatment of latent tuberculosis is important to prevent children from developing active tuberculosis. This study aimed to compare the effectiveness, safety, compliance, and cost of the currently available Latent Tuberculosis Infection treatment regimens, 6 months isoniazid (6H) and 3 months isoniazid plus rifampicin (3HR), based on the 2020 Department of Health National Tuberculosis Control Program Tuberculosis Preventive Treatment guidelines for children. Methodology: In this open label randomized controlled trial pilot study, 30 participants were assigned to receive either 6H or 3HR. Medications were administered daily by either participants (with direct supervision of treatment supporters) or treatment supporters (for younger participants). Data on outcome measures in terms of effectiveness, safety, and compliance were obtained. Direct cost of treatment was computed per patient’s weight category. Independent Z-test for proportion (for effectiveness, safety, and compliance) and mean (for cost) at 5% level of significance was used to compare the outcomes for each treatment group. Results: Twelve subjects (67%) in the 6H group completed per-protocol therapy, compared to 10 subjects (87%) in the 3HR group. The proportion of adverse events was higher in the 6H group (22%) compared to the 3HR group (8%), but statistical tests showed no significant difference for both compliance and frequency of adverse events. No participant developed active TB disease in both groups. The cost of the 6H treatment regimen was 2,180.18 Php while the cost of the 3HR treatment regimen was 1,526.41 Php, with a p-value of 0.0470 which was statistically significant. Conclusions Both 6H and 3HR are effective treatments for latent TB infection in patients 0-18 years old. Both treatments were comparable in terms of safety and ease of compliance, but overall cost was higher in the 6H treatment regimen.

Mycobacterium tuberculosis (MTB) is a rare cause of prosthetic joint infection. The diagnosis is challenging especially in cases of latent tuberculosis. QuantiFERON-TB Gold (QFT®) is an interferon-gamma relative assay (IGRA) which is highly specific and sensitive for detection of MTB infection. We report a case of 76-year-old lady diagnosed with tuberculous prosthetic joint infection following total knee replacement. Histological examination of abnormal synovial tissue taken intraoperatively reveals chronic granulomatous lesion and raised suspicion of tuberculous infection in otherwise asymptomatic patient. The tuberculin skin test, MTB acid-fast stain and tuberculosis polymerase chain reaction were negative. The diagnosis dilemma was solved with positive result of QuantiFERON TB Gold Test. The patient was treated with anti-tuberculous drug without any surgical intervention. At five months follow-up, patient was clinically well with no symptoms and signs of infection

Tuberculosis (TB) is an infectious disease that poses a serious threat to human health. About a quarter of the world's population were infected with Mycobacterium tuberculosis in 2020, and the majority of them were latently infected. Approximately 5%-10% of the population with latent tuberculosis infection may progress to active TB disease. Identifying latent TB infection from active TB by biomarkers and screening people with latent TB infection at high risk of progression for preventive treatment by biomarkers that can reliably predict the progression is one of the most effective strategies to control TB. This article reviews the progress of research on transcriptional and immunological biomarkers for identifying TB infection and predicting the progression from latent infection to active TB, with the aim of providing new ideas for tuberculosis control.

BACKGROUND/AIMS: The objective of this study was to determine the efficacy and safety of add-on therapy with certolizumab pegol (CZP) in active rheumatoid arthritis (RA) patients of a single ethnicity. METHODS: In this 24-week, phase 3, randomized, double-blind, placebo-controlled trial, eligible patients (n = 127) were randomized 2:1 to subcutaneous CZP + methotrexate (MTX; 400 mg at week 0, 2, and 4 followed by 200 mg every 2 weeks) or placebo + MTX. RESULTS: At week 24, the American College of Rheumatology criteria for 20% (ACR20) response rate was significantly greater with CZP + MTX than with placebo (66.7% vs. 27.5%, p < 0.001). Differences in ACR20 response rates for CZP vs. placebo were significant from week 1 (p < 0.05) and remained significant through week 24. The CZP group reported significant improvement in physical function and disability compared to the placebo group (p < 0.001) at week 24, as assessed by Korean Health Assessment Questionnaire-Disability Index (KHAQ-DI). Post hoc analysis indicated that the proportion of patients who had ACR70 responses, Disease Activity Score 28 (DAS28) low disease activity, and DAS28 remission at week 24 was greater in CZP + MTX-treated patients who achieved a decrease in DAS28 ≥ 1.2 (43.8%) at week 4 than in nonresponders. Among 18 (22.2%) and 14 patients (35.0%) in CZP and placebo groups who had latent tuberculosis (TB), none developed active TB. Most adverse events were mild or moderate. CONCLUSIONS: CZP treatment combined with MTX in active RA patients with moderate to severe disease activity and an inadequate response to MTX resulted in rapid onset of efficacy, which is associated with better clinical outcome at week 24 and has an acceptable safety profile, especially in an intermediate TB-burden population.
