Severe metabolic acidosis in the alcoholic: differential diagnosis and management.

1. A chronic alcoholic with severe metabolic acidosis presents a difficult diagnostic problem. The most common cause is alcoholic ketoacidosis, a syndrome with a typical history but often misleading laboratory findings. This paper will focus on this important and probably underdiagnosed syndrome. 2. The disorder occurs in alcoholics who have had a heavy drinking-bout culminating in severe vomiting, with resulting dehydration, starvation, and then a beta-hydroxybutyrate dominated ketoacidosis. 3. Awareness of this syndrome, thorough history-taking, physical examination and routine laboratory analyses will usually lead to a correct diagnosis. 4. The treatment is simply replacement of fluid, glucose, electrolytes and thiamine. Insulin or alkali should be avoided. 5. The most important differential diagnoses are diabetic ketoacidosis, lactic acidosis and salicylate, methanol or ethylene glycol poisoning, conditions which require quite different treatment. 6. The diagnostic management of unclear cases should always include toxicological tests, urine microscopy for calcium oxalate crystals and calculation of the serum anion and osmolal gaps. 7. It is suggested here, however, that the value of the osmolal gap should be considered against a higher reference limit than has previously been recommended. An osmolal gap above 25 mosm/kg, in a patient with an increased anion gap acidosis, is a strong indicator of methanol or ethylene glycol intoxication.

[Acute facial mucormycosis in a diabetic subject. Successful treatment with Amphotericin B].

A 29 year old male, admitted with diabetic keto-acidosis, was found to have rhinocerebral phycomycosis (mucormycosis) involving the left eye and the left hard palate with perforation into the maxillary antrum. Despite late diagnosis, full recovery was obtained following intravenous Amphotericin B (total dose : 3.015 gm in 4 months) and extensive surgery (debridement and unilateral eye enucleation). The circumstances of onset of the disease and its clinical characteristics are discussed; the main features of its management are analyzed.

Lactic acidosis and hypoglycemia in a patient with high-grade non-Hodgkin's lymphoma and elevated circulating TNF-alpha.

A 71-year-old patient with high-grade non-Hodgkin's lymphoma stage IVB, severe lactic acidosis and tumor-associated hypoglycemia is described. Endocrine causes of hypoglycemic episodes were excluded because of low serum concentrations of insulin and "insulin-like growth factor 1", and normal concentrations of growth hormone and thyroid hormone. Clinical conditions associated with lactic acidosis such as diabetes mellitus, biguanide intoxication, septicemia, acute hypoxemia, or circulatory insufficiency were ruled out. Enhanced glucose metabolism within the tumor was visualized by positron emission tomography employing 2-fluro-2-deoxy-D-glucose (FDG) as a tracer. A markedly elevated tumor necrosis factor-alpha (TNF-alpha) level was found which decreased after cytoreductive therapy paralleling the normalization of serum lactate. In contrast to the majority of cases of lymphoma-associated lactic acidoses reviewed to date, in our case lactate elimination was not reduced.

Diabetes and infarcted papillary thyroid cancer.

A young black Jordanian lady who has type one diabetes, chronic diabetic complication and ischemic heart disease, presented with a picture of diabetic keto-acidosis, precipitated by an acute neck swelling. This was suggestive of acute suppurative thyroiditis with abscess formation causing compressive symptoms. This unfortunate patient had an eventful course despite aggressive treatment by antibiotics and surgery and then succumbed of an acute cardiac event. The operative tissue biopsy revealed an abscess in an infarcted papillary thyroid cancer. We believe this is a rare presentation of such an association with a fatal outcome.

[Clinical characteristics of renal damage in patients with accidental hypothermia].

We have investigated the clinical characteristics of renal damage and associated complications of 79 patients with accidental hypothermia whom we encountered over the last 5 years. All patients were male, with an average age of 58.9 +/- 9.2 years. Most of these patients were homeless. Body temperature on admission was 29.3 +/- 3.0 degrees C. The most common clinical manifestations on admission were consciousness disturbance and severe hypotension. Complications, including increase in serum transaminase, alcoholism, pneumonia, liver cirrhosis, sepsis, diabetes mellitus, hypoglycemia, acidosis, and an increased level of serum CPK and amylase were found frequently on admission. Death within 48 hours after admission occurred in 23 cases (the death rate; 23/79 = 29%). Renal damage was found in 36 cases (36/79 = 46%), consisting of acute renal failure (ARF) in 27, and acute on chronic in 6. Urinary diagnostic indices suggested that the etiological factor for ARF was pre-renal, which responded well to passive rewarming and an appropriate fluid replacement therapy, resulting in full recovery in most of the cases (the recovery rate; 25/27 = 93%). Among patients with renal damage, there were no cases requiring dialysis. The present data suggest that accidental hypothermia is a fatal condition with an extremely high death rate. It also is associated with multiple complications including ARF. The main cause for ARF is pre-renal, possibly caused by cold diuresis or dehydration superimposed on the underlying diseases such as alcoholism, diabetes mellitus, liver cirrhosis. Such complications, independent of renal damage, determine the patient's prognosis.

[Effect of multi-glycosides of tripterygii on latent autoimmune diabetes in adults in early stage].

OBJECTIVE: To observe the effect of multi-glycosides of tripterygii (MT) on latent autoimmune diabetes of adults (LADA) in early stage. METHODS: The diabetic patients were divided randomly into the control group treated with insulin alone and the treated group treated with insulin and MT. Levels of insulin, C-peptide, glutamic acid decarboxylase antibody (GADAb) and islet cell antibody (ICA) were detected and clinical features of the disease were observed. RESULTS: There was no difference between the control group and the treated group in body mass index (BMI), the occurrence of diabetic keto-acidosis and the function of liver and kidney (P >0.05). After 6 months' treatment, the positive rate of GADAb and ICA decreased, plasma levels of fasting and 2 hrs post-prandial C-peptide and also 2 hrs post-prandial true insulin in the treated group increased (P <0.01), while all the above indexes improved more significantly after 1 year's treatment (P <0.01). CONCLUSION: Compared treatment of insulin with multi-glycosides of tripterygii in early stage of LADA has better effects in relieving autoimmune injury and recovering function of pancreatic island than insulin alone.

[Lactic acidosis and metformin implicated: why better information about risk factors?].

In type II diabetes treated with metformin (Glucophage) lactic acidosis is a rare adverse reaction, fatal in approximately 50 per cent of cases. Metformin is implicated by plasma and intra-erythrocyte levels. An analysis is carried out on available information about this risk for healthcare professionals and for patients. A comparison is made of approved labelling information on Glucophage and its patient leaflets in France and in the USA and an analysis made of the differences. In France, Information given to physicians, pharmacists and patients on the risk of lactic acidosis where Glucophage is implicated must be improved, and on the interest of the metformin plasma level in this case. These are primary points because the issue for the few patients concerned may be fatal. Advice on self-medication may be introduced. The evolution of information provided on these risks depends on the pharmaceutical laboratory, government authorities and healthcare professionals.

Hemoperfusion in diabetic coma.

Hemoperfusion on ionic exchange resins in the therapy of diabetic keto-acidosis (DKA) coma is proposed. Resins used are strong anionic resins in mixed form able to release bicarbonates and to trap ketoanions and organic anions in a stoichiometric manner. A series of trials in open circuit are performed in order to search for a suitable mixture of resins and to establish the amounts of HCO3- and ketoanions respectively released or entrapped. Therefore, ten simulated hemoperfusions in closed circuit systems were performed, utilizing cartridges containing 1,700 g of mixed resin (9% HCO3- form and 91% Cl- form). The results indicate that all side effects of bicarbonate i.v. therapy of DKA coma are avoided because of the smooth HCO3- administration to the patient. Furthermore, a good removal of ketoanions and organic acids is obtained without changing the blood osmolality.

[A case of lactic acidosis caused by buformin in an oldest elderly diabetic patient].

A 93-year-old male was urgently admitted to our hospital with dyspnea and disturbance of consciousness. The patient had been visiting a general physician regularly for ten years, for treatment of type 2 diabetes. He had been treated with glibenclamide and voglibose, until voglibose was replaced with buformin 3 months before admission. During pre-admission treatment, his HbA1c was 10-12% and serum Cr level was around 2mg/dL, but insulin therapy had never been considered because of "being too old". The patient had started taking furosemide one year before admission, because of edema of the lower legs, and also spironolactone two months before admission. Anorexia had continued for one month before admission on May 29, 2003. On admission, his laboratory data were; blood glucose 87mg/dL, HbA1c 12.5%, BUN 75mg/dL, Cr 3.9mg/dL, lactate 253.1 mg/dL, and blood gas analysis; pH 6.97, anion gap 45.3mmol/L breathing room air, suggesting marked lactic acidosis with renal failure. Intensive care with bicarbonate and fluid therapy was successful, and his glycemic control improved markedly with insulin. On the other hand, his activity of daily living (ADL) severely deteriorated while in hospital Home follow-up was therefore not indicated, and he had to change a hospital for further follow-up. This case report gives rise to the question of how we should manage diabetes in the oldest elderly, including the use of insulin and biguanides. In addition, complications of biguanides in the elderly are reviewed.
