After an inability to work lasting 15 months with 9 treatments in an inpatient department in several institutions in a 33-year-old patient the relapsing metabolic alkalosis in hypopotassiaemia and relapsing increase of the creatinine level could causally be clarified by establishment of a pylorus stenosis in chronic duodenal ulcer. Due to the Billroth II operation a complete clinical and objective improvement developed. In this case the transient retention of substances normally contained in the urine was conditioned by a hypokalaemic nephropathy. The cause of the hypokalaemia was the vomiting by pylorus stenosis. The histologically ascertained glomerulonephritis had no causal significance for the pathological process.

Drug-induced acid-base disorders may be classified into four categories with respect to the mechanism. 1. Metabolic acidosis is induced by a large acid loads incurred from exogenous sources (e.g. NH4Cl, or toxin ingestion) or endogenous acid production (e.g. generation of ketoacids or lactic acids by alcohol or phenformin) or base loss (e.g. abuse of laxatives). 2. Metabolic alkalosis results from exogenous bicarbonate loads (e.g. milk-alkali syndrome) or effective extracellular fluid contraction, potassium depletion plus hyperaldosteronism (e.g. vomiting, diuretics, or licorice). 3. Renal tubular acidosis is induced by the drugs which mainly impair proximal and/or distal tubules (e.g. vitamin D, NSAID, acetazolamide or amphotericin B). 4. Respiratory acidosis or alkalosis results from drug-induced respiratory center depression or neuromuscular impairment (e.g. anesthetic, sedative overdosage or curare) or hyperventilation (salicylates, paraldehyde, epinephrine, or nicotine).

The mechanisms of acid base balance in digestive organs, including stomach, intestine as well as liver, have been described in the present paper. The stomach secrets large amount of acid as well as sodium bicarbonate, so that hydrogen ion would be lost in the severe vomiting state such as pyloric stenosis, resulting in metabolic alkalosis and hypokalemia. In the diarrheal condition, sodium bicarbonate would be lost in large amount, causing metabolic acidosis and hypokalemia. Hepatic failure induces the respiratory alkalosis of which mechanisms have not been clarified yet. In any case, urgent correction of acid base imbalnce would be crucial. It is, however, obscure to date how the systemic acid base imbalnce affects the function of the digestive system. This issue would be promising field in the investigation of digestive diseases.

A 32-year-old man was diagnosed as having pseudo-Bartter syndrome due to surreptitious habitual vomiting and to maldigestion related to decayed teeth. His chief complaints were muscle pain and weakness. In this case, metabolic alkalosis, hypokalemia, hypochloremia, increased plasma renin activity and aldosterone levels were noticed with marked decreases in urinary chloride excretion. Creatinine clearance (GFR) and renal plasma flow (RPF) were also decreased. Blood pressure was normal, but the pressor response to angiotensin II was attenuated. Before treatment with 0.9% saline infusion, plasma vasopressin (AVP) was not suppressed sufficiently by lowering the plasma osmolality (Posm) with an oral water load (WL), but it normally responded to a rise in Posm due to hypertonic saline infusion. Moreover, plasma AVP was normally suppressed by WL after the replenishment of saline. Plasma atrial natriuretic peptide (ANP) was low before WL, but increased normally in response to WL. However, inconsistent with the normal response in this case, decreases in plasma AVP failed to dilute urinary osmolality and to increase urine flow, irrespective of the levels of plasma ANP. These results indicate that chronic inanition due to surreptitious vomiting causes impaired renal diluting ability through decreases in GFR and RPF, irrespective of the levels of plasma AVP and ANP.

Over 10% of emergency room patients are diagnosed as having alcohol (6.0%) or drug intoxication. In the present study 196 alcohol intoxications treated in a hospital were studied retrospectively; 49.2% of the patients had abnormal acid-base values, alcoholics more often than non-alcoholics (p = 0.04). Mean blood ethanol concentration (BAC) was 310 mg/dl (SD 120); alcoholics had higher concentrations of alcohol. BAC was the higher the lower the serum pH was (p less than 0.002, r = -0.45). The deeper the coma the lower the serum pH (p less than 0.05) and the higher the BAC (p less than 0.0001). Respiratory acidosis (31.7%) was an important finding in those intoxicated. Metabolic acidosis (7.9%) could be explained by the presence metabolites of ethanol in the serum and by decreased extra-cellular fluid volume. Metabolic alkalosis related to vomiting and an extra-cellular fluid volume decrease was found in 7.9% of the patients. Respiratory alkalosis was a rare finding (1.6%). Hypokalemia (22.5%) and hypernatremia (15.3%) were the most important electrolyte changes. Chronic alcoholics had lower serum potassium than had non-alcoholics; 3.6% (n = 7) of the patients had to be intubated. Acid-base disturbances were frequent in adults with alcohol intoxication. Serum pH correlated well with the state of consciousness and the BAC.

A 74-year-old male was admitted to hospital with acute rhabdomyolysis and myoglobinuria due to hypokalemia. The hypokalemia resulted from diuretic treatment. He had no family history of myopathy, and no diarrhea and vomiting. The neurological examination revealed painful quadriplegia. The blood pressure was 160/74 mm Hg. Laboratory examination showed hypokalemic and hypochloremic metabolic alkalosis (serum K 1.5 mEq/l, serum Cl 89 mEq/l, base excess + 20.9, HCO3- 44.9 mmol/l, pH 7.563) and marked elevations of serum CPK, LDH, GOT, GPT and myoglobin. Endocrinological and renal functions were normal. Muscle biopsy revealed marked necrosis with remarkable phagocytosis and vacuolar degeneration. The cessation of diuretics and intravenous infusion of potassium chloride resulted in a marked improvement in clinical and laboratory findings. The diuretics-induced hypokalemic myopathy is rare in the literature.

A patient with end-stage renal disease (ESRD) developed metabolic alkalosis and alkalemia from protracted vomiting. As a result of the absence of the alkali excretory capacity in this patient with ESRD, the alkaline load accumulated rapidly. Once the amount of acid lost from vomiting exceeded the amount of acid gained from metabolism, alkalemia supervened. The initial arterial blood gas on room air revealed hypercarbia, hypoxia and alkalemia. Her serum bicarbonate was greater than 50 mEq/l. Compensatory hypoventilation occurred. In this report, the extent of compensatory hypoventilation in the setting of metabolic alkalosis in patients treated for ESRD and therapeutic approaches to this problem will be discussed. Treatment was aimed at correcting the primary disorder, namely metabolic alkalosis. Conventional bicarbonate dialysis was shown to be effective in improving acid-base homeostasis in this patient.

Between January 1980 and December 1987, ten Saudi Arabian children at Saudi Arabian Oil Co. (Saudi Aramco) health care facilities in the Eastern Province of Saudi Arabia had cystic fibrosis (CF). The incidence of CF in Saudi Arab children less than or equal to 14 years was 1 in 4243. Five of the ten children had hypoelectrolytaemia and metabolic alkalosis on initial presentation. Two of the five had recurrent vomiting, hypoelectrolytaemia and metabolic alkalosis alone and initially no chest symptoms. Early exclusion of CF should be part of the workup in any child, especially in an infant with hypoelectrolytaemia and metabolic alkalosis.

A 6-month-old infant suffering from cystic fibrosis is reported. In spite of an apparently appropriate treatment and in absence of respiratory infection, the patient showed progressive anorexia, intermittent vomiting and weight loss. These non-specific signs and symptoms could all be explained by metabolic alkalosis and disappeared immediately after oral supplementation with sodium and potassium chloride. This unusual metabolic complication should be searched for in every cystic fibrosis infant with unexplained anorexia and failure to thrive.

Metabolic alkalosis is defined as a primary increase in plasma bicarbonate concentration. As a consequence of this increase, systemic alkalemia and secondary hypercapnia develop. In most instances metabolic alkalosis arises from loss of acid through the kidney or gastrointestinal tract. The causes of metabolic alkalosis can be separated into two groups. Those forms of alkalosis responsive to chloride salt administration (e.g., vomiting), are associated with extracellular fluid volume and chloride depletion. In contrast, alkalosis resistant to administration of chloride salt (e.g., primary aldosteronism), is usually associated with extracellular fluid volume expansion and a urine chloride above 20 mEq/L (mmol/L). Metabolic alkalosis; causes; diagnosis; clinical manifestations.
