Diabetics on dialysis in the Republic of Macedonia: A nationwide epidemiological study

BACKGROUND

Incidence increase of diabetes mellitus (DM) has taken epidemic proportions in the world. Diabetic nephropathy (DN) is a most serious complication, taking a leading place as a factor in the progression of chronic kidney disease (CKD). Dialysis treatment of these patients is complex, expensive, and exerts an excessive burden on the health budgets of the affected countries.

METHODS

We performed a nationwide precise observational study with the aim of analysing diabetics on dialysis in dialysis centres throughout the Republic of Macedonia (RM) in 2002 and in 2006; to compare the results from patients records; and to gather data on the epidemiology, clinical characteristics and complications of diabetes type 1 (DM1) and diabetes type 2 (DM2).

RESULTS

The prevalence of HD patients in RM was 1114 vs 1074 in 2002 and 2006, respectively. Of these, 109 (9.78%) vs. 115 (10.71%) had DM in 2002 and 2006, respectively. The percentage of diabetics on dialysis between different centers varied between 3% to 21% vs. 2.4% to 22.07% in 2002 and 2006, respectively. The mean age of the patients was 58+/-10.29 vs. 56.5+/-10.71 in 2002 and 2006, respectively. Patients with DM1 were 19 (17.43%) vs. 15 (13.04%) and with DM2 were 90 (82.57%) vs. 100 (86.96%) in 2002 and 2006, respectively. 28 (25.68%) vs. 31 (26.96%) patients were on oral anti-diabetic drugs and 62 (57.21%) vs. 69 (60%) patients were on insulin in 2002 and 2006, respectively. Mean age of DM1 patients was 47+/-11.6 y. vs. 45+/-7.32 y. respectively and of DM2 was 60.37+/-8.33 y. vs. 61.14+/-10.23 y., in 2002 and 2006, respectively. Mean time of insulin treatment was 9.5+/-6.63 y. vs. 10.85+/-9.29 y. in 2002 and 2006. Mean Body Mass Index (BMI) was 26.4 vs. 23.49+/-4.74 kg/m2 in DM1 and 25.5 vs. 24.77+/-3.70 kg/m2 in DM2 patients in 2002 and 2006, respectively. Thrombosis of first arteriovenous fistulae (AVF) occurred in 41% vs. 25.22% in 2002 and 2006, respecttitvely. Hepatitis C virus (HCV) infection was confirmed in 57% vs. 44% of DM patients in 2002 and 2006, respectively. Most common co-morbidity in patients was hypertension, 91% vs. 80.87% in 2002 and 2006, respectively.

CONCLUSION

The number of diabetics on dialysis in the Republic of Macedonia did not increase in the period from 2002 to 2006. In DM2 diabetics on dialysis the frequency of complications is higher and time on dialysis is shorter than in DM1 patients. Early detection of diabetic nephropathy by primary care physicians as well as collaborative treatment by diabetologists, nephrologists, cardiologists and ophthalmologists before and during dialysis are important for improvement of treatment and survival of diabetic patients on dialysis.

Internal carotid artery hypoplasia presenting as anterior ischemic optic neuropathy

PURPOSE

To describe the occurrence of anterior ischemic optic neuropathy in a young woman with internal carotid artery hypoplasia.

METHODS

Case report with clinical and radiologic observations.

RESULTS

A 38-year-old woman suffered from a sudden, painless loss of vision in her right eye. The diagnosis of anterior ischemic optic neuropathy was based on the clinical course and appearance of the fundus. Doppler evaluation of the carotid arteries, computed tomography (CT) scan, magnetic resonance imaging (MRI), and CT angiogram all demonstrated internal carotid artery hypoplasia on the same side.

CONCLUSION

Although carotid artery disease (mainly atherosclerosis) is not a common predisposing factor for anterior ischemic optic neuropathy, our patient had an ipsilateral coexisting internal carotid artery hypoplasia and anterior ischemic optic neuropathy. We believe that the carotid artery anomaly might have contributed to the development of anterior ischemic optic neuropathy in this patient.

[Staging of rectal carcinoma by endorectal ultrasonography]

Staging of rectal carcinoma is essential for its management. 23 patients with rectal lesions were examined by endorectal ultrasonography. Of these 19 had rectal carcinoma and in 4 there was an abscess of the rectal wall, previously diagnosed by sigmoidoscopic biopsy. 10 of those with carcinoma were examined by computerized tomography as well, and 10 were operated on. In most cases the staging of rectal carcinoma by endorectal ultrasonography was accurate and compared well with the operative histological results. We conclude that endorectal ultrasonography is the method of choice for staging of rectal carcinoma prior to treatment.
