Abstract

Despite scientific advances, extended forms of pulmonary tuberculosis are still relevant. The aim of our study was to determine clinical features and outcome of extended pulmonary tuberculosis in immunocompetent patients. Retrospective comparative study including 100 patients HIV negative, presenting pulmonary tuberculosis divided into 2 groups of 50 patients (group1: extended tuberculosis and group2: localized tuberculosis). Tuberculosis was considered extended when reaching above one lobe. The average age was comparable in the 2 groups (p = 0.138). In group1, we noted a higher incidence of diabetes (p = 0.037) and malnutrition (p = 0.045). Clinically, patients in group1 had more general signs (p=0.033) and dyspnoea (p=0.037). Biologically, anemia (p<0.001), leukocytosis (p=0.05), elevated CRP (p=0.031), thrombocytosis (p=0.023), hyponatremia (p = 0.001) and liver disturbances (p = 0.001) were significantly more frequent in group1. Concerning the evolution, time to smear negativity was significantly longer (p=0.012). Similarly, radiological sequelae were more frequent (p = 0.02) and more extensive (p = 0.012). Positive predictive value of radiological extent in disease evolution was 62% with a confidence interval between 47.2%...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
