Genotyping and spatial analysis of pulmonary tuberculosis and diabetes cases in the state of Veracruz, Mexico.

Background: Genotyping and georeferencing in tuberculosis (TB) have been used to characterize the distribution of the disease and occurrence of transmission within specific groups and communities.

Objective: The objective of this study was to test the hypothesis that diabetes mellitus (DM) and pulmonary TB may occur in spatial and molecular aggregations.

Material And Methods: Retrospective cohort study of patients with pulmonary TB.

Molecular clustering of patients with diabetes and pulmonary tuberculosis: A systematic review and meta-analysis.

Introduction: Many studies have explored the relationship between diabetes mellitus (DM) and tuberculosis (TB) demonstrating increased risk of TB among patients with DM and poor prognosis of patients suffering from the association of DM/TB. Owing to a paucity of studies addressing this question, it remains unclear whether patients with DM and TB are more likely than TB patients without DM to be grouped into molecular clusters defined according to the genotype of the infecting Mycobacterium tuberculosis bacillus. That is, whether there is convincing molecular epidemiological evidence for TB transmission among DM patients.

Different types of samples from a 27-year-old female patient who was diagnosed AIDS after presenting an acute respiratory picture caused by Pneumocistis carinii, in 1997, were studied. From that moment on, the patient continued having respiratory pictures repeatedly, until she was admitted at "Pedro Kouri" Institute of Tropical Medicine with a chronic diarrheical picture, significant loss of weight and extreme anorexia, together with a constant wet cough, fever, etc. The necessary complementary tests were made and a hyperergic Mantoux and very low levels of CD4 cells (under 200 cells/m3) outstood.

[Report of Mycobacterium avium-intracellulare associated with kidney mycobacteriosis].

Consecutive samples of urine from a patient presenting radiological images of multicystic kidneys were microbiologically analyzed searching the possible presence of acid-alcohol resistant bacilli. The patient had already undergone complementary tests, which evidenced a kidney failure. As a result, it was isolated a slow-growth non pigmented mycobacterial strain corresponding to group III of Runyon.
