Cavitary tuberculosis

Ranjana Arora, Lisa Armitige, Audrey Wanger, Robert L Hunter, Shen-An Hwang
Trehalose 6,6'dimycolate (TDM) is a glycolipid found in nearly pure form on the surface of virulent Mycobacterium tuberculosis (MTB). This manuscript investigated the production of TDM, growth rate and colony morphology of multiple strains of MTB, each of which had been isolated from both pulmonary (sputum) and extrapulmonary sites of multiple patients. Since sputum contains MTB primarily from cavities and extrapulmonary biopsies are typically granulomas, this provided an opportunity to compare the behavior of single strains of MTB that had been isolated from cavities and granulomas...

Pulmonary cavitation is one of the most frequently observed clinical characteristics in tuberculosis (TB). The objective of this study was to investigate the potential risk factors associated with cavitary TB in China. A total of 385 smear-positive patients were enrolled in the study, including 192 (49.9%) patients with cavitation as determined by radiographic findings. Statistical analysis revealed that the distribution of patients with diabetes in the cavitary group was significantly higher than that in the non-cavitary group (adjusted odds ratio (OR) (95% confidence interval (CI)):12...

BACKGROUND: Tuberculosis-diabetes co-morbidity (TB-DM) is characterized by increased inflammation with elevated circulating levels of inflammatory cytokines and other factors. Circulating angiogenic factors are intricately involved in the angiogenesis-inflammation nexus. METHODS: To study the association of angiogenic factors with TB-DM, we examined the systemic levels of VEGF-A, VEGF-C, VEGF-D, VEGF-R1, VEGF-R2, VEGF-R3 in individuals with either TB-DM (n = 44) or TB alone (n = 44)...

OBJECTIVES: Patients with tuberculosis (TB) often present with weight loss. Lack of weight gain with TB treatment has been associated with treatment failure. The purpose of this study was to examine patterns of weight gain in patients with TB and determine the disease characteristics that predict weight gain. METHODS: This was a retrospective cohort study of adults with TB treated in a county health system in the USA. Demographic, clinical, radiographic, and microbiological data were recorded in addition to monthly weights during treatment...

Pulmonary tuberculosis is commonly presented as cavitary lesion and infiltrations. It commonly involves upper lobe. Lower lobe involvement is less common. Various atypical presentations of tuberculosis on radiology are reported like mass, solitary nodule, multi lober involvement including lower lobes. Atypical presentations are more commo in patients with immunocompromised conditions like Diabetes Mellitus, anemia, renal failure, liver diseases, HIV infection, malignancy, patients on immunosuppressive therapy...

Tuberculosis (TB) infection in pregnant women and newborn babies is always challenging. Appropriate treatment is pivotal to curtail morbidity and mortality. TB diagnosis or exposure to active TB can be emotionally distressing to the mother. Circumstances can become more challenging for the physician if the mother's TB status is unclear. Effective management of TB during pregnancy and the postpartum period requires a multidisciplinary approach including pulmonologist, obstetrician, neonatologist, infectious disease specialist, and TB public health department...

Cavitation is a key pathological feature of human tuberculosis (TB), and is a well-recognized risk factor for transmission of infection, relapse after treatment and the emergence of drug resistance. Despite intense interest in the mechanisms underlying cavitation and its negative impact on treatment outcomes, there has been limited study of this phenomenon, owing in large part to the limitations of existing animal models. Although cavitation does not occur in conventional mouse strains after infection with Mycobacterium tuberculosis, cavitary lung lesions have occasionally been observed in C3HeB/FeJ mice...

1,25-dihydroxyvitamin D3 [1,25(OH)2D3] is a powerful immuno-modulator, which enhances expression of antimicrobial peptides and induces autophagy in monocytes/macrophages. Since 1,25(OH)2D3 increases the phagocytic potential of monocytes/macrophages, we have explored the effect of 1,25(OH)2D3 on the expression of receptors such as mannose receptor (CD206) and DC-SIGN (CD209) as well as autophagy genes such as ATG5 and Beclin-1 (BECN1) in monocytes/macrophages of healthy controls (HCs) and pulmonary tuberculosis (PTB) patients with and without cavitary disease...

PURPOSE: Loss and gain-of-function (GOF) mutations in human signal transducer and activator of transcription 1 (STAT1) lead to distinct phenotypes. Although recurrent infections are common to both types of STAT1 mutations, GOF mutations are distinguished by chronic mucocutaneous candidiasis and autoimmunity. However, the clinical spectra of STAT1 GOF mutations continue to expand. We here describe two patients with STAT1 GOF mutations presenting early in life with combined immunodeficiency (CID)...

The differential diagnoses of a cavitary lung lesion in renal transplant recipients would include infection, malignancy and less commonly inflammatory diseases. Bacterial infection, Tuberculosis, Nocardiosis, fungal infections like Aspergillosis and Cryptococcosis need to be considered in these patients. Pulmonary cryptococcosis usually presents 16-21 mo after transplantation, more frequently in patients who have a high level of cumulative immunosuppression. Here we discuss an interesting patient who never received any induction/anti-rejection therapy but developed both BK virus nephropathy as well as severe pulmonary Cryptococcal infection after remaining stable for 6 years after transplantation...

Pulmonary artery pseudoaneurysms have classically been associated with the cavitary lesions of reactivation tuberculosis and termed Rasmussen's aneurysm. There have been relatively few case reports of pulmonary artery pseudoaneuryms arising secondary to cavitary pneumonia. We present a case of pulmonary artery pseudoaneurysm occurring secondary to cavitating aspiration pneumonia that was treated successfully with coil embolization.

The occurrence of pulmonary tuberculosis (PTB) and lung cancer as comorbidities has been extensively discussed in many studies. In the past, it was well known that lung cancer is a specific epidemiological successor of PTB and that lung cancer often develops in scars caused by PTB. In recent years, the relevance of the two diseases has drawn attention in terms of the close epidemiological connection and chronic inflammation-associated carcinogenesis. In Japanese case series studies, most lung cancer patients with tuberculous sequelae received supportive care alone in the past, but more recently, the use of aggressive lung cancer treatment is increasing...

INTRODUCTION: Tuberculosis is one of the most important public health problem worldwide. Detecting patients with active pulmonary Koch's disease is an important component of tuberculosis control programs. However, at times in patients even with a compatible clinical picture, sputum smears do not reveal acid-fast bacilli and smear-negative pulmonary tuberculosis remains a common problem. AIM: The present study is aimed to compare the results of induced sputum and bronchial washings smear in patients suspected to have sputum smear negative pulmonary tuberculosis...
