Features of the simultaneous course of pulmonary aspergillosis and tuberculosis on the background of type 1 diabetes mellitus (clinical case)

Abstract

Aim. To analyze the features of the simultaneous course of pulmonary aspergillosis and multidrug-resistant pulmonary tuberculosis (MDR-TB) on the background of type 1 diabetes mellitus, on the example of a clinical case of our practice.

Materials and methods. Clinical case of our practice of simultaneous pulmonary aspergillosis and MDR-TB on the background of type 1 diabetes mellitus in a patient, who was treated in Pulmonary tuberculosis department No. 2 of clinical base of Phthisiatry and Pulmonology Department of Zaporizhzhia State Medical University at Communal Non-Commercial Enterprise of the “Zaporizhzhia Regional Clinical and Diagnostic Center of Phthisiatry and Pulmonology” of Zaporizhzhia Regional Council.

Results. In the presented clinical case, the patient had been suffering from diabetes mellitus for 8 years and had been receiving insulin therapy for all these years. One year before the TB disease, he had contact with an index patient, but he categorically refused a course of preventive chemotherapy. Also, the patient did not make a comparison X-ray TCO after 6 months, as a contact person.

MDR-TB and aspergilloma of the left lung of the patient were diagnosed simultaneously on the background of severe condition with decompensated form of type 1 diabetes mellitus, severe intoxication syndrome and inflammatory process, massive hemoptysis. Aspergilloma of the left lung was diagnosed using X-ray TCO and cultural examination of bronchial aspirate for Aspergillus, which was not difficult to diagnose. Diagnosis of MDR-TB was also not difficult, because the patient had MBT, which contributed to the timely and correct appointment of antimycobacterial therapy. Surgery for aspergilloma of the left lung was contraindicated, as the type 1 diabetes was in decompensation. Persistent hyperglycemia remained, despite the fact of antifungal therapy and constant correction of insulin therapy prescribed for the patient. Endocarditis quickly developed in the patient, which was the reason of patient’s death.

Conclusions. The decompensated form of type 1 diabetes mellitus caused persistent hyperglycemia, which was the reason of immune disorders and this made the patient’s body susceptible to bacterial (MDR-TB) and fungal (aspergillosis) infections, which led to the development of the complication of endocarditis and death. A big mistake in his case, was a categorical refusal by the patient to receive a course of preventive chemotherapy, as a contact person with an index patient. In view of this, in the presence of type 1 diabetes, the patient should have not neglected it. And as a result, the patient had a MDR-TB, one year after. At the same time, the patient did not make a comparison X-ray TCO, after 6 months, as a contact person, which was a possible reason for the missing of early diagnosis of pulmonary aspergilloma.

That’s why, a correct treatment of type 1 diabetes mellitus and timely preventive radiological examination of the thoracic cavity organs are especially important, as the diabetes mellitus is the most common premorbid background for TB and aspergillosis.
