ACTA ENDOCRINOLOGICA (BUC)

At the end of 2019, a novel coronavirus was identified as the cause of a cluster of pneumonia in China and it spread quickly to other countries. Although Covid-19 causes severe pneumonia, it is known that it can be associated with different diseases and prognosis of disease can be due to many of disorders such as hyponatremia. A 65-year-old female patient with sarcoidosis, cronic obstructive lung disease, hypertension and congestive heart failure presented to the emergency department with shortness of breath and fever. Oropharyngeal swab for Covid-19 PCR test was positive. After the initiation of treatment, the patient developed hyponatremia. This case is remarkable because there is no reported case of Covid-19 and inappropriate ADH syndrome coexistence and it demonstrates that there may be a correlation between Covid-19 infection prognosis and hyponatremia.

Aim is to evaluate atherosclerotic risk factors and carotid intima media thickness [CIMT] in offspring of type 2 Diabetes Mellitus [DM] patients with normal glucose tolerance. Methods. We evaluated 96 offspring of Type 2 DM patients and 39 healthy control who were in similar age, sex and body mass. We measured fasting blood glucose [FBG], postprandial blood glucose [PBG], insulin, uric acid, homocystein, fibrinogen, HOMA-IR, lipid profile, hsCRP, microalbuminuria, glycosylated hemoglobin A1c and CIMT by Doppler ultrasonography. Results. FBG was found higher in study group [p<0.001]. The HOMA-IR was 1.7±0.98 and 1.2±0.58 mg/dL x uUI/mL for study and control group, respectively [p=0.007]. TCholesterol, triglycerides, HDL-C, LDL-C and homocystein levels were not different. HsCRP and fibrinogen levels were higher in study group [p=0.014 and p=0.035, respectively]. Microalbuminuria levels were higher in study group but not significant [p=0.111]. CIMT in study group increased distinctively [p<0,001]. In regression analysis, being in study group causes a significant increase on the mean CIMT level by 0.057 mm [0.029-0.086] Conclusion. Our study demonstrated that various atherosclerotic risk factors are aggregated in offspring of Type 2 DM patients having NGT even before they develop glucose intolerance. Having a diabetic family alone might be effective in developing increased CIMT.

Context. Retinal microvascular dysfunction differs in macular edema lesions in the two eyes of the same patient with diabetic retinopathy. Objective. To evaluate the relationship between central macular thickness (CMT) and metabolic/systemic factors including anthropometric and laboratory findings, in patients with regressed diabetic retinopathy and a history of pars plana vitrectomy (PPV) combined with internal limiting membrane peeling in one eye. Subjects and Methods. Forty-two eyes with PPV and the same patients’ fellow 42 eyes (without PPV) included this study. Fasting blood samples of these 42 diabetics were collected to study adiponectin levels and other routine parameters. Results. The average hemoglobinA1c value was 7.3±1.3%. CMT of the vitrectomized eyes were significantly correlated with atherogenic index of plasma, total cholesterol, low density lipoprotein cholesterol and uric acid (UA). On the other hand, CMT of the nonvitrectomized fellow eyes significantly correlated with glucose levels and diabetes duration. Adiponectin, adiponectin/body mass index, adiponectin/fibrinogen were found significantly higher in the subgroup with CMT≥300µm in the vitrectomized eyes (P<0.05). UA levels were higher in the subgroup with CMT≥300µm in the fellow (nonvitrectomized) eyes (P<0.05). Conclusions. Although there was no relationship between CMT and hemoglobinA1c values, CMT seemed to be affected by atherogenicity, prooxidant chemical alterations in the course of inflammation, so determination of adiponectin and UA levels may be suggested before surgery to predict the atherosclerotic damage and the postoperative CMT value. Vitrectomy performed at the proper time may be helpful in metabolic remodeling process of the retinal tissue along with life style changes, well control of diabetes, and intraocular treatments.
