[Changes in lens and retina and parameters of lipid metabolism and glycosylated hemoglobin levels in young patients with diabetes].

PURPOSE: The aim of the work was, to find out the relations between the lipid profile and glycosylated hemoglobin in blood and eye changes in the diabetic young people. MATERIAL AND METHODS: There were 39 patients (19 women and 20 men), aged 14-27 years (mean 19.5), treated for diabetes during the period 6-23 years (mean 9.6). The ophthalmological examinations have included anterior segment and lens, as well as the fundus of the eye. There also have been made the blood serum examinations of cholesterol (CHC), LDL-CHC, HDL-CHC, trigliceride (TG), apolipoproteins B (ApoB) and glycosylated hemoglobin (HbA1c). RESULTS: Basing on these examinations it has been stated that: 1. the lens changes were observed in the patients of increased LDL-CHC level and ApoB, who suffered from diabetes shorter than 10 years, while in the patients suffering longer, lens changes correlate with the high level of HbA1c; 2. the eye fundus changes correlated substantially in the patients with the high levels of HbA1c, TG, HDL-CH (negatively), LDL-CH and ApoB, suffering less than 10 years; in the patients suffering longer, correlation was also with the increased level of HbA1c, CHC and LDL-CHC. 3. The increased levels of lipids were noted in the patients with the high level of HbA1c. CONCLUSIONS: The stated data have indicated, that the eye changes are caused by disturbances of lipid parameters, but besides of the glycaemia disorders. The diabetic duration does not matter for the lipid profile and HbA1c level, but it is important for the occurrence of eye fundus changes. The HbA1c essentially influences on the occurrence of eye fundus changes, but in the longer suffering patients, also on the lens changes. The high HbA1c level shifts the lipid profile towards atherogenic factors. It is purposeful, to decrease its level below 7%, which is accepted as good diabetes control.

[Hemoglobin level and lactate concentration in calves kept under extensive and intensive husbandry conditions].

The influence of different housing systems on hemoglobin content and lactate concentration in the blood of 42 calves in a suckler cow herd of the breeds Deutsche Schwarzbunte and Deutsche Rotbunte, and 34 male veal calves of the breeds Deutsche Schwarzbunte and Holstein-Friesian was examined in a period from the first to the fifth month of life. The results are the follows: In calves of the suckler cow herd the hemoglobin content increases continuously, whereas the hemoglobin peak in veal calves is in the second month of life. Divergent values in favour of calves in the suckler cow herd are indicated from the twelfth week of life. In comparison of hemoglobin content with an earlier investigation in calves from the same suckler cow herd an annual rhythm can be assumed. In blood lactate, significant differences between the experimental groups are determined from the second month of life with the higher values in veal calves, except the third month with higher values in suckling calves. The results are discussed in connection with feeding milk replacer as on feed ration or a whole milk/milk replacer mixture in veal calves, and compared with the conditions of extensive farming animals in a suckler cow herd.

Chemoradiation of unresectable pancreatic carcinoma: impact of pretreatment hemoglobin level on patterns of failure.

AIM: To evaluate, in patients with locally advanced pancreatic carcinoma undergoing concomitant chemoradiation, the impact of pretreatment hemoglobin (Hb) concentration on the outcome in terms of clinical response, local control, metastasis-free survival, disease-free survival, and overall survival. PATIENTS AND METHODS: 30 patients undergoing concomitant chemoradiation (5-fluorouracil [5-FU], 1,000 mg/m(2)/day, continuous i.v. infusion days 1-4 of radiotherapy) and external beam radiotherapy (50.4-59.4 Gy) were divided into two groups based on pretreatment median Hb value (11.5 g/dl). The potential prognostic factors examined besides Hb concentration were: tumor site (head vs body-tail), sex (female vs male), cN (cN0 vs nC1), dose of external beam radiotherapy (50.4 Gy vs 59.4 Gy), presence of jaundice at diagnosis (yes vs no), weight loss at diagnosis (> or = 5 kg vs < 5 kg), epigastric-lumbar pain at diagnosis (yes vs no), maximum tumor diameter (< 40 mm vs > or = 40 mm). RESULTS: Pretreatment Hb ranged between 9.6 and 15.0 g/dl. No statistically significant differences were observed as for clinical response and local control between patients with an Hb < or = 11.5 g/dl and those with an Hb > 11.5 g/dl. Metastasis-free survival was 5.1 months in patients with an Hb < or = 11.5 g/dl and 10.7 months in patients with an Hb > 11.5 g/dl (p = 0,010). Median actuarial disease-free survival was 5.1 and 10.2 months in patients with an Hb < or = 11.5 and > 11.5 g/dl, respectively (p = 0.026). Median actuarial overall survival was 7.5 and 10.3 months in patients with an Hb < or = 11.5 and > 11.5 g/dl; respectively (p = 0.039). On multivariate analysis, Hb concentration at diagnosis was the only factor prognostically correlated with metastasis-free survival (p = 0.026), disease-free survival (p = 0.032), and overall survival (p = 0.048). CONCLUSION: In a group of patients with locally advanced pancreatic carcinoma treated with chemoradiation, a significant correlation was observed between pretreatment Hb levels and metastasis-free survival, disease-free survival, and overall survival.

Erythropoietin and transferrin concentrations during pregnancy in relation to hemoglobin levels.

Serum levels of erythropoietin (EPO) were assayed by ELISA at the same time as red blood cells (RBC), hemoglobin (Hb), hematocrit (Hct), serum iron and transferrin in 136 pregnant women, divided on the basis of hemoglobin values (> or < or = 10.5 g/dl) and weeks of pregnancy (< or > or = 27th week). In the overall population, a parallel increase with weeks of pregnancy was shown by serum concentrations of EPO expressed as a logarithm (multiple R = 0.367, P < 0.0001), and transferrin levels (multiple R = 0.529, P < 0.0001). It was found that EPO levels did not differ significantly between anemic and non-anemic patients before the 27th week, but the difference became highly significant (P < 0.01) after the 27th week in favour of anemic patients. Before the 27th week, the correlations between log EPO and RBC, Hct, Hb and iron were not significant, whereas the correlation between log EPO and transferrin was significant (P < 0.01); after the 27th week, the correlations and significance of the regression found were: log EPO vs Hb (Pearson coefficient = -0.384; P < 0.001), vs Hct (Pearson coefficient = -0.370; P < 0.01), vs transferrin (Pearson coefficient = 0.392; P < 0.0001), vs iron (Pearson coefficient = -0.274, P < 0.05). In the population divided according to Hb levels, the correlation was positive and significant in both groups between log EPO and transferrin (Hb > 10.5 g/dl: Pearson coefficient = 0.524, P < 0.0001; Hb < or = 10.5: Pearson coefficient = 0.614, P < 0.0001), but was inverse and significant only in the group with Hb < or = 10.5 g/dl between log EPO and serum iron (Pearson coefficient = -0.481, P < 0.01). The variations in EPO were related to Hb levels after the 27th week of pregnancy and were closely correlated with transferrin over the whole period. The physiological mechanism of these changes is discussed.

Diabetes control improved when inner-city patients received graphic feedback about glycosylated hemoglobin levels.

OBJECTIVE: To develop and test an inexpensive visual tool to help patients with diabetes improve glycemic control. METHODS: A multidisciplinary team developed a 1-page form, the "Take-home Diabetes Record" (THDR), providing feedback to patients by displaying per cent glycosylated hemoglobin (GHb) values graphically over time, with target levels highlighted. Patients with type 2 diabetes in an inner-city clinic were randomized to THDR use (n = 57) or not (n = 70) over 15 months. Self-care activities were discussed, linked with GHb results, and charted at each clinic visit. Initial and final GHb were compared. RESULTS: Mean GHb fell significantly in THDR patients (-0.94, P =.003), but not in control patients (-0.18, P =.36). Mean GHb decrease was greater in THDR patients (P =.047). A greater proportion of THDR patients (51%) than control patients (18%) achieved a decrease in GHb >/=0.9 (P =.001). CONCLUSIONS: A graph linking GHb and self-care activities shows promise for improving glycemic control.
