[Pulmonary mycosis in patients with diabetes mellitus. Clinical characteristics and risk factors].

BACKGROUND

Diabetes mellitus is a public health problem in Mexico, and the trend of the disease is increasing. From 2000 to 2017, 7.32 million new cases were diagnosed, with pulmonary mycoses being one of the most serious complications.

AIMS: To describe the frequency and the clinical characteristics of patients diagnosed with pulmonary mycoses, and to identify the risk factors associated with this entity.

METHODS

Case-control study, paired by gender (1:1-3) and age (± 5 years), that analyzed patients with pulmonary mycosis (mucormycosis, histoplasmosis, coccidioidomycosis, blastomycosis, aspergillosis, cryptococcosis, paracoccidioidomycosis) and studied the risk factors present in each patient.

RESULTS

From the 162 patients studied, 56 suffered pulmonary mycosis and 106 were controls. The median of the age was 51 and 50 years for the cases and for the controls, respectively. Multiple logistic regression analysis showed that patients with diabetes mellitus had an odds ratio of 8,3 (p < 0.001), and patients with a history of tuberculosis had an odds ratio of 8,8 (p < 0.001).

CONCLUSIONS

Our results show that 52% of the patients with pulmonary mycoses had a history of diabetes mellitus. Diabetes mellitus is a relevant risk factor for pulmonary mycoses, which are usually diagnosed in advanced stages and have a high mortality.
