The impact of COVID-19 pandemic on glycemic control in patients with diabetes mellitus in Turkey: a multi-center study from Kocaeli.

AIMS: The aim of this study is to determine the impact of the COVID-19 pandemic on the management and disease control of the patients with diabetes mellitus in Kocaeli. METHODS: This study was carried out in six leading central hospitals in five major districts of Kocaeli. The study was conducted between June 2020 and November 2020. The patients who had previous admissions to these clinics within 6 months prior to the pandemic were enrolled in the study. RESULTS: A total of 283 patients were enrolled in the study, among them 151 (53%) patients were female, 268 (95%) had type 2 DM and remaining 5% had type 1 DM. The median weight of the patients was similar between the previous and last visits (84 kg vs 83 kg, p = 0,88). Laboratory parameters of previous and current visits revealed that mean fasting plasma glucose (FPG) and HbA1c levels were not significantly changed. The number of the patients who had controlled blood pressure was significantly decreased. The number of those who had neuropathic complains and the severity of dyslipidemia significantly increased during pandemic period. CONCLUSION: Our study demonstrated that despite decreased compliance with diet and exercise, and difficulty in accessing medication, there was no significant change in weight, FPG and HbA1c levels in diabetic patients. Since cultural differences, education level and socioeconomic opportunities differ between societies, national and international studies will be more accurate to evaluate the effects of epidemics on the course of chronic diseases.

Association between IL-18 gene polymorphisms and Hashimoto thyroiditis.

BACKGROUND: Hashimoto's thyroiditis (HT), which is also called lymphocytic thyroiditis, is the most frequent autoimmune thyroid disease (AITD), in which T helper-1 lymphocytes mediate the disease. IL-18 is expressed in thyroid follicular cells (TFCs) during HT. The findings of studies aimed at investigating the relationship between IL-18 and HT are highly contradictory. In this study, we aimed to investigate the association between IL-18 gene polymorphisms and HT. METHODS AND RESULTS: The study included 97 patients diagnosed with HT and 86 volunteers in the healthy control group. The IL18-607C/A (rs1946518) and -137G/C (rs187238) genotypes were determined using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. No significant difference in the mean age or sex was observed between the groups (p = 0.763 and p = 0.658, respectively). The -137 IL18 CG genotype was more frequent in HT patients than in controls. In HT patients, the risk of the IL-18 CG genotype was more than 2.237 times higher (OR 2.237%95 Cl 1.195-4.187, p = 0.039) than that of the G/G genotype. Additionally, the -607 AC genotype was more frequent in the control group than in the HT group (in individuals with the IL18 CG genotype). CONCLUSIONS: According to our results, the CG genotype might be a risk factor for HT. Conversely, there is a possibility that the AC genotype plays a protective role against the condition. However, further studies will contribute to new solutions by revealing the molecular and cellular mechanisms of HT.

Differentiation of insulinoma from accessory spleen by 99mTc-labelled heat-denaturated red blood cell scintigraphy: case report.

BACKGROUND: Neuroendocrine tumors (NETs) are rare tumors harboring overexpression of somatostatin receptors (SSTRs) on their cell membrane. Because some organs, such as the spleen, adrenal glands and liver, physiologically express SSTR, it might be challenging to distinguish some pancreatic NETs located in the pancreatic tail from the accessory spleen next to the splenic hilum. In this manuscript, we report a case with hypoglycemia attack and 2 different masses displayed by Gallium 68-tetraazacyclododecane tetraacetic acid-octreotate (68Ga-DOTATATE) positron emission tomography/computed tomography (PET/CT). CASE PRESENTATION: A 63-year-old woman presented to the hospital with confusion and profuse sweating. Biochemical diagnosis of insulinoma was established. 68Ga-DOTATATE PET/CT revealed two masses with increased tracer uptake located adjacent to the splenic hilum and inferior pole of the spleen which were initially reported as two separate accessory spleens. Then, 99mTc-labelled heat-denaturated red blood cell (99mTc-HDRBC) scintigraphy-single-photon emission computed tomography (SPECT)/CT was performed to distinguish a NET in the pancreatic tail from accessory spleen at the splenic hilum. Enhanced tracer uptake remained in the inferior pole of spleen, but not in the splenic hilum. The lesions were suggestive of insulinoma in the pancreatic tail and an accessory spleen adjacent to the inferior pole of the spleen. CONCLUSION: Approximately 10% of the population have an accessory spleen which can show similar imaging characteristics with pancreatic NETs, especially if located in the pancreatic tail. In our presented case, 99mTc-HDRBC scintigraphy-SPECT/CT is a useful nuclear medicine method to differentiate a NET in the pancreatic tail from accessory spleen at the splenic hilum which may avoid unnecessary surgeries in the presence of enhanced tracer uptake or vice versa.

Is decline in serum albumin an ominous sign for subsequent peritonitis in peritoneal dialysis patients?

Serum albumin levels have been used as a representative marker for morbidity and mortality in the dialysis population. We evaluated the significance of various biochemical values in peritoneal dialysis (PD) patients with a history of peritonitis. In 51 patients [27 women, 24 men; mean age: 42.6 years (range: 19 - 70 years); average duration of PD: 28.26 +/- 23.1 months] with history of peritonitis, we recorded serum albumin and cholesterol levels at the beginning of PD, at the last visit (1 month) before the peritonitis episode, and at months 1, 6, and 12 after the peritonitis episode. Routine data from peritoneal equilibration tests were also obtained. Serum albumin showed a significant decline from the basal measurement at the measurements 1 month before and after the peritonitis episode (p = 0.026 and 0.025 respectively). Serum cholesterol levels and dialysate-to-plasma creatinine at hours 2 and 4 revealed no significant alterations at the same time points. The decline in serum albumin relative to the first visit (basal level) may be a factor showing the likelihood of peritonitis. A decline in serum albumin during follow-up may be an indicator for subsequent peritonitis. The absence of a similar decline in serum cholesterol levels (mimicking albumin) may rule out low dietary intake or malnutrition. Pathophysiologic explanations for these relationships are not obvious. If the leading complication of PD is peritonitis, efforts should be focused on improving the factors that influence serum albumin levels.
