Microscopic polyangiitis in a case of silica exposure: a rare presentation.

Microscopic polyangiitis in a case of silica exposure: a rare presentation. Monaldi Arch Chest Dis. 2019 Sep 10;89(3): Authors: Gupta N, Mahendran AJ, Chakrabarti S, Agrawal S Abstract A 28-year-old male was admitted for breathlessness, haemoptysis, fever and fatigue. The patient had occupational exposure to silica dust. Arterial blood gas test ABG revealed hypoxemic respiratory failure. Chest CT demonstrated ground glass opacities with interlobular septal thickening and small centrilobular nodules with patchy areas of consolidation in bilateral lungs. He was mechanically ventilated for refractory hypoxemia. The treatment with cyclophosphamide and methylprednisolone lead to recovery and extubation. The final diagnosis was diffuse alveolar haemorrhage due to perinuclear antineutrophil cytoplasmic antibody (ANCA)-associated microscopic polyangiitis (p-ANCA-associated MPA). In a tuberculosis endemic country, for patients presenting with diffuse alveolar haemorrhage (DAH), with history of silica exposure, differential diagnosis of ANCA associated vasculitis must be considered.

The molecular imprinting matrix is developed strategically by molecular modelling via density functional theory. 3-Thiophene acetic acid was predicted as suitable functional monomer for imprinting ethionamide. Polymeric film was formed on the surface of glassy carbon electrode by electropolym...

Conclusions: Naturally acquired sexual stage immunity, as detected by antibodies to Pfs230 and Pfs48/45, was present in most studies analyzed. Significant between-study heterogeneity was seen, and methodological factors were a major contributor to this, and prevented further analysis of epidemiological and biological factors. This demonstrates a need for standardized protocols for conducting and reporting seroepidemiological analyses.

Akintola, A. LalliAbstractTumour necrosis factor-α (TNF-α) inhibitors are increasingly being used as immunomodulators to manage inflammatory conditions such as rheumatoid arthritis and Crohn’s disease. Reported serious side effects include an increased incidence of lymphoma and greater susceptibility to infections such as tuberculosis. The aim of this systematic review was to find out whether there is an ...

The Spanish cattle TB surveillance system consists of three components: a) routine skin testing, b) slaughterhouse surveillance, and c) pre-movement controls. Our objectives were to assess the effectiveness of the whole surveillance system and evaluate th...

ConclusionsThe quantiferon test is recommended in the evaluation of people with retinal vasculitis. Interpretation of a positive result can be challenging in a country nonendemic for TB. The majority of patients with quantiferon-positive retinal vasculitis were found to have latent TB.

Authors: Guleria R, Mahashur A, Ghoshal AG, Thomas PK, Raghu G, Baughman RP Abstract  Sarcoidosis is a chronic, systemic disease of unknown etiology that affects multiple organs. The disease was considered rare in developing countries like India. More recently sarcoidosis is being increasingly diagnosed in countries where tuberculosis continues to be endemic. There is a general perception among physicians that the prevalence of sarcoidosis has increased over the last two decades in countries like India. This may be true but could also be related to better awareness of the condition, availability of improved di...

Conclusions The pathogenesis of IRVAN syndrome is uncertain. One of the postulates is that the features of arterial aneurysms and other retinal vascular alterations occur secondary to acquired inflammatory reaction. We hypothesize that IRVAN syndrome may be a morphological diagnosis possibly associated with various entities, one of which could be ocular tuberculosis. It may be prudent to rule out intraocular tuberculosis in cases labeled as IRVAN syndrome in an endemic population.
