A 44-year-old male presented with a history of defective vision in the right eye for the past 5 months with the previous history of tubercular cervical lymphadenitis. On examination, right eye revealed panuveitis with dense vitritis and chorioretinitis in the superotemporal quadrant. His Mantoux test was positive (25 mm × 25 mm induration), QuantiFERON-TB Gold was test positive, aqueous aspirate was positive for Mycobacterium tuberculosis genome, negative for viruses and toxoplasma, and hence he was initiated on four-drug antitubercular therapy (ATT) with oral steroids...

Initially diagnosed with cervical lymphadenitis, a 15-year-old boy was started with category I anti-tuberculosis (TB) drugs. Follow-up investigations led to isolation and identification of Mycobacterium lentiflavum by multiple diagnostic and identification approaches. Observation of this rare pathogen from human origin urges cautious diagnosis while attending TB cases.

INTRODUCTION: Tunisia has one of the highest burdens of extrapulmonary tuberculosis (EPTB) among tuberculosis (TB) cases but the contribution of MTBC-mediated human EPTB is unknown. EPTB diagnosis is challenging due to the paucibacillary nature of clinical samples. Therefore, a need of a simplified molecular method for sensitive and specific TB detection and differentiation of MTBC members caused EPTB remains a priority to an early diagnosis, optimize successful anti-TB treatment and minimize transmission...

Suppurative lymphadenitis is one of the severe complication after BCG vaccination, but its diagnostic criteria and treatment guidelines have not yet been established. In this article, we describe a case of suppurative lymphadenitis caused by BCG vaccination and propose diagnostic criteria and treatment guidelines of the disease. The lymphadenitis was presented as skin involving mass and was completely extirpated. Pathological evaluation revealed a necrotising lymphadenitis, consistent with the diagnosis of BCG lymphadenitis...

Immune thrombocytopenia (ITP) is an auto-immune condition that results in isolated thrombocytopenia associated with possibly lethal haemorrhage. In its secondary form, ITP can be triggered by many infectious and non-infectious conditions. Secondary ITP associated with tuberculosis (TB) has rarely been described in the literature. We report on a 22-year-old patient presenting with hypermenorrhoea and petechiae due to ITP secondary to tuberculous lymphadenitis. Normalisation of thrombocytopenia was only achieved after initiation of anti-tuberculosis treatment following failure of thrombocyte substitution and immune-modulatory treatment...

Tuberculous lymphadenitis (TBL) is characterized by an expansion of Th1 and Th17 cells with altered serum levels of proinflammatory cytokines. However, the cytokine profile at the site of infection, i.e., the affected lymph nodes, has not been examined in detail. To estimate the baseline and mycobacterial antigen-stimulated concentrations of type 1, type 17, and other proinflammatory cytokines in patients with TBL (n = 14), we examined both the baseline and the antigen-specific concentrations of these cytokines before and after chemotherapy and compared them with those in individuals with pulmonary tuberculosis (PTB) (n = 14)...

BACKGROUND: Bacille Calmette-Guérin (BCG) is the world's most widely distributed vaccine, used against tuberculosis (TB), in cancer immunotherapy, and in autoimmune diseases due to its immunomodulatory properties. To date, the effect of BCG vaccination on antibody responses to host proteins has not been reported. High-content peptide microarrays (HCPM) offer a unique opportunity to gauge specific humoral immune responses. METHODS: The sera of BCG-vaccinated healthy adults were tested on a human HCPM platform (4953 randomly selected epitopes of human proteins) to detect specific immunoglobulin gamma (IgG) responses...

A 29-year-old British Pakistani woman presented with a 2-month history of drenching fevers, night sweats, lethargy and tender cervical and axillary lymphadenopathy. Initial investigations, bloods and imaging were unremarkable. Fever persisted during her admission, and treatment for tuberculosis (TB) lymphadenitis was started postbiopsy until histology confirmed a diagnosis of Kikuchi-Fujimoto's disease (KFD). KFD has a non-specific presentation of fever, night sweats and lymphadenopathy and commonly raises a clinical suspicion of a number of other serious conditions such as TB, lymphoma, HIV, systemic lupus erythematous, toxoplasmosis and infectious mononucleosis...
