Severe metabolic acidosis in adult patients with Duchenne muscular dystrophy.
Duchenne muscular dystrophy (DMD) leads to progressive paresis, respiratory failure and premature death. Long-term positive pressure ventilation can improve quality of life and survival, but previously unrecognized complications may arise. We analyzed the characteristics of severe metabolic acidosis occurring in 8 of 55 DMD patients, of 20-36 years of age, observed over a 5-year period. All patients were on positive pressure ventilation and were being treated for chronic constipation. Before admission, they had had a reduced intake of fluids and food. Upon examination, they were severely ill, dyspneic and suffering from abdominal discomfort. Metabolic acidosis with a high anion gap was noted in 5 of the 8 patients and with a normal anion gap in the other 3. They all recovered after the administration of fluids and nutrition, the regulation of bowel movements and treatment with antibiotics, as appropriate. Metabolic acidosis is a life-threatening, potentially preventable complication in older DMD patients. Early recognition, subsequent administration of fluids, nutrition and antibiotics and regulation of bowel movements seem to be essential.

[Electrolyte abnormalities and metabolic acidosis in two Duchenne muscular dystrophy patients with advanced congestive heart failure].
We experienced two Duchenne muscular dystrophy patients with advanced congestive heart failure, who showed abrupt severe hyponatremia, hyperkalemia and metabolic acidosis. Two patients received respiratory management, parenteral nutrition, and drugs including angiotensin converting enzyme inhibitors (ACEI). The patient 1 who was 19 years old showed abdominal pain, hematuria, diarrhea and disorientation. Laboratory findings were as follows; Na 120 mEq/L, K 7.3 mEq/L, BUN > 140 mg/dl (scale over), ACTH 20.2 pg/ml, cortisol 25 micrograms/dl, renin 40.7 ng/ml/hr and aldosterone 203 ng/dl. Arterial blood gas analysis (ABG) showed metabolic acidosis (pH 7.232). Combination therapy with hydrocortisone, glucose-insulin therapy (GIT) and NaHCO3 successfully rescued this patient. The patient 2 (28 years of age) was admitted to our hospital because of congestive heart failure. Laboratory findings were as follows; Na 129 mEq/L, K 5.5 mEq/L, BUN 60 mg/dl, cortisol 21 micrograms/dl, renin 36 ng/ml/hr and aldosterone 47 ng/dl. He complained abdominal discomforts from the next day of admission. Ten days after the admission Na, K and BUN were 111 mEq/L, 6.2 mEq/L and 154 mg/dl, respectively. ABG showed compensated metabolic acidosis. He fell into shock during GIT therapy. Laboratory findings at that time were as follows; Na 108 mEq/L, K 3.2 mEq/L, ACTH 77.6 pg/ml, cortisol 24 micrograms/dl, renin 58 ng/ml/hr and aldosterone 24 ng/dl. Although hydrocortisone was introduced, he could not recover and died. There are some reports about life-threatening electrolyte abnormalities and metabolic acidosis in the patients receiving ACEI. These phenomena were more frequent in patients with renal dysfunction and/or congestive heart failure. Hyponatremia, hypovolemia, combination therapy with nonsteroidal anti-inflammatory drugs (NSAID) and/or potassium sparing diuretics were reported as risk factors. We could not prove the correlation between the acute changes in our cases and ACEI. However ACEI is suspicious, because many of these risk factors were observed in our cases. Aldosterone was extremely elevated in the patient 1 when potassium was severely elevated. On the other hand, the patient 2 showed lower aldosterone level after correction of potassium than that on admission. Potassium is regarded as a major secretion factor of aldosterone for patients receiving ACEI. The fact the patient 2 fell into shock during GIT, tells us that we should use steroid simultaneously when we try to Topics: Acidosis; Adult; Angiotensin-Converting Enzyme Inhibitors; Anti-Inflammatory Agents, Non-Steroidal; Diuretics; Glucose; Heart Failure; Humans; Hydrocortisone; Hyponatremia; Insulin; Male; Muscular Dystrophy, Duchenne; Risk Factors; Sodium Bicarbonate; Treatment Outcome; Water-Electrolyte Imbalance | 2000 |
