[Metabolic efficiency of carbostimulin in therapy of acidosis with diabetes].

The total content of ketoacids, ketonic bodies and state of acid-base balance in blood of sugar diabetes patients was studied as affected by 10-day complex therapy with application of carbostimulin. It is established that carbostimulin lowers the content of ketonic bodies, increases the total content of ketoacids, concentration of buffer bases, CO2, HCO3-. Application of the complex therapy without the preparation causes only a tendency to study the mentioned indexes for the same period of the treatment.

Influence of acidosis on protein metabolism.

Acidosis is a common clinical condition with both chronic and acute forms. Chronic metabolic acidosis induces an increase in protein degradation; however, its effects on protein synthesis are less clear. Metabolic acidosis increases net whole-body proteolysis by a massive increase in protein degradation and only a moderate increase in protein synthesis. Most studies in humans on the relation between acidosis and protein metabolism have concentrated on patients with chronic renal failure with metabolic acidosis. However, because chronic renal failure is associated with other abnormal metabolic conditions such as malnutrition, it is difficult to separate out the effects on protein metabolism solely due to acidosis. Data on the influence of other forms of acidosis, e.g., respiratory acidosis, diabetic ketoacidosis, and lactic acidosis, on protein turnover are sparse. Similarly, data about the influence of acidosis on the metabolism of other proteins, such as the liver-produced secretory proteins, are lacking. Future research should more vigorously investigate the influence of acidosis on protein metabolism in various clinical conditions and the potential regulatory effects on the metabolism of secretory proteins. The reversal of acidosis might prove to have beneficial effects on protein wasting, and thus decrease morbidity and possibly mortality.

A survey of reports of quetiapine-associated hyperglycemia and diabetes mellitus.

OBJECTIVE: To explore the clinical characteristics of hyperglycemia in patients treated with quetiapine. METHOD: A pharmacovigilance survey of spontaneously reported adverse events in quetiapine-treated patients was conducted using reports from the U.S. Food and Drug Administration MedWatch program (January 1, 1997, through July 31, 2002) and published cases using the search terms hyperglycemia, diabetes, acidosis, ketosis, and ketoacidosis. RESULTS: We identified 46 reports of quetiapine-associated hyperglycemia or diabetes and 9 additional reports of acidosis that occurred in the absence of hyperglycemia and were excluded from the immediate analyses. Of the reports of quetiapine-associated hyperglycemia, 34 patients had newly diagnosed hyperglycemia, 8 had exacerbation of preexisting diabetes mellitus, and 4 could not be classified. The mean +/- SD age was 35.3 +/- 16.2 years (range, 5-76 years). New-onset patients (aged 31.2 +/- 14.8 years) tended to be younger than those with preexisting diabetes (43.5 +/- 16.4 years, p = .08). The overall male:female ratio was 1.9. Most cases appeared within 6 months of quetiapine initiation. The severity of cases ranged from mild glucose intolerance to diabetic ketoacidosis or hyperosmolar coma. There were 21 cases of ketoacidosis or ketosis. There were 11 deaths. CONCLUSION: Atypical antipsychotic use may unmask or precipitate hyperglycemia. UPDATE: An additional 23 cases were identified since August 1, 2002, the end of the first survey, by extending the search through November 30, 2003, bringing the total to 69.

Influenza infection and diabetes mellitus. Case for annual vaccination.

Herein, epidemiological data on influenza pneumonia and mortality, results of clinical studies, and the outcome of influenza vaccination trials are reviewed. All excess mortality studies that specify for underlying disease list diabetes as one of the major risk factors. During influenza epidemics, death rates among patients with diabetes mellitus may increase by 5-15%. Diabetes mellitus is also mentioned as a risk factor in most clinical studies, making up 3-14% of the patients studied. Even in recent studies, diabetes mellitus is only preceded as a risk factor by cardiovascular disease and chronic pulmonary disorders. To what extent cardiovascular disease and old age contribute to the increased influenza mortality and morbidity in diabetic patients remains unclear. The influence of epidemic influenza on the incidence of diabetic acidosis in combination with an impaired immune response to both Staphylococcus aureus and the influenza virus suggests that diabetes mellitus itself is the main risk factor. It is concluded that all patients with diabetes mellitus should receive annual vaccinations and that, in official recommendations, patients with diabetes mellitus should be mentioned as a separate risk group. Whole-virus vaccines are preferred over subunit vaccines.

[Association of hyperlipidemia, acute pancreatitis and diabetic keto-acidosis. A case report (author's transl)].

A 32-year-old man was admitted semi-comatose with digestive troubles to the hospital. A diabetic keto-acidosis was discovered. The diabetes was known by the patient for one year and a half, but it was not treated. Furthermore the laboratory studies showed a hyperlipidemia (type V) and an increase in pancreatic enzymes. The hyperlipidemia disappeared with insulin therapy. The chronology of the facts was probably: a hyperlipidemia associated with the diabetes, responsible of an acute pancreatitis, which induced a keto-acidosis.
