Bacterial infections among patients with diabetes in Papua New Guinea
1Department of Clinical Sciences, Faculty of Medicine, University of Papua New Guinea, Boroko.
Abstract:
This study reports the morbidity that resulted from bacterial infections in Melanesian patients with non-insulin-dependent diabetes who attended the Port Moresby General Hospital, Papua New Guinea, between January 1, 1982 and June 30, 1984. Fifty-three of 160 patients with diabetes experienced 66 episodes of infection, 48 of which required inpatient hospital treatment. The average length of stay in hospital was 37.6 days per episode of infection. Of 88 patients who were newly-diagnosed as diabetic during this period, 30 patients initially had presented with a bacterial infection. The lower limb was the site that was infected most frequently, and Staphylococcus aureus and Klebsiella pneumoniae were the usual causative organisms. Eleven patients had bacterial gangrene of the foot; two of these patients were less than 23 years of age, and five patients were not known to have had diabetes previously. Five patients were suffering from pulmonary tuberculosis; the annual incidence of tuberculosis in this study group (12.5 cases/1000 patients) was about 11-times higher than that which has been reported for the general population. Thirteen patients with diabetes died in hospital during the study period. Infection was the cause of death in nine patients and three of these patients were less than 25 years of age. The morbidity of infection can be controlled if diabetes is sought more frequently in patients with infections, and if glycaemia can be controlled. This will have to be achieved through existing primary health-care structures, as resources for diabetes-specific preventive programmes in developing countries will be limited.
Insights
Bacterial infections caused significant illness and death in Melanesian patients with non-insulin-dependent diabetes. Early detection of diabetes and better blood sugar control are crucial for managing infection morbidity in these patients.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Endocrinology
Background:
- Non-insulin-dependent diabetes mellitus (NIDDM) is a growing health concern globally, particularly in developing regions.
- Bacterial infections pose a significant threat to individuals with diabetes, leading to increased morbidity and mortality.
- Melanesian populations present unique epidemiological profiles for chronic diseases and infections.
Purpose of the Study:
- To investigate the incidence and characteristics of bacterial infections in Melanesian patients with NIDDM.
- To determine the common causative organisms and affected sites of infection.
- To assess the impact of these infections on patient outcomes, including hospitalization and mortality.
Main Methods:
- Retrospective analysis of medical records of diabetic patients attending Port Moresby General Hospital from January 1982 to June 1984.
- Identification of infection episodes, causative agents, affected body sites, and treatment outcomes.
- Comparison of tuberculosis incidence in the study group with the general population.
Main Results:
- 66 infection episodes occurred in 53 of 160 diabetic patients, with 48 requiring hospitalization (average stay 37.6 days).
- Lower limb infections were most common, caused primarily by Staphylococcus aureus and Klebsiella pneumoniae.
- Eleven patients developed bacterial foot gangrene; five were previously undiagnosed diabetics. Tuberculosis incidence was 11 times higher than in the general population.
- Nine of thirteen diabetic deaths were infection-related, with three occurring in patients under 25.
Conclusions:
- Bacterial infections contribute substantially to morbidity and mortality in Melanesian NIDDM patients.
- Prompt diagnosis of diabetes in infected individuals and effective glycemic control are essential for reducing infection-related complications.
- Strengthening primary healthcare is vital for managing diabetes and preventing infections, given limited resources for specialized programs in developing countries.
