Overview

Milk-alkali syndrome (also known as calcium-alkali syndrome) is characterized by a history of excessive calcium intake and hypercalcemia, metabolic alkalosis and varying degrees of renal insufficiency. In 1915, Bertram Sippy introduced a treatment for peptic ulcer disease which was an hourly mixture of milk and cream combined with alkaline powders. In 1923, the toxic effects of Sippy’s regimen were reported for the first time. With the introduction of histamine antagonists and decrease in antacid consumption since the 1970s, the incidence of milk-alkali syndrome has decreased significantly. However, since the 1990s, there has been an increase in milk-alkali syndrome due to an increase in calcium and vitamin D consumption in postmenopausal women for osteoporosis prevention. Treatment of milk-alkali syndrome is mostly supportive and mainly includes the withdrawal of the offending agent, hydration, and intravenous volume expansion. Prognosis of milk-alkali syndrome is generally good and early diagnosis and treatment, with the withdrawal of the offending agent and supportive therapy, usually resolve the symptoms and abnormalities in milk-alkali syndrome (hypercalcemia, alkalosis and renal insufficiency).

Historical Perspective

In 1915, Bertram Sippy introduced a treatment for peptic ulcer disease which was an hourly mixture of milk and cream combined with alkaline powders.^[1] In 1923, the toxic effects of Sippy’s regimen was reported for the first time.^[2] With the introduction of histamine antagonists and decrease in antacid consumption since the 1970s, the incidence of milk-alkali syndrome has decreased significantly. However, since the 1990s, there has been an increase in milk-alkali syndrome due to increase in calcium and vitamin D consumption in postmenopausal women for osteoporosis prevention.^[3]^[4]^[5]

Classification

Milk-alkali syndrome may be classified as the following: acute (toxemic form), subacute (Cope's syndrome) and chronic (Burnett's syndrome).^[6]

Pathophysiology

The exact pathogenesis of milk-alkali syndrome is unknown. Hypercalcemia in milk-alkali syndrome involves several mechanisms including: intestinal absorption of calcium is increased, bone buffering of calcium becomes saturated, and renal excretion of calcium is decreased.^[5] Several factors that increase bicarbonate reabsorption and contribute to the alkalosis in milk-alkali syndrome include: volume depletion due to increased sodium and free water excretion caused by increased calcium intake, suppression of PTH, direct tubular effects of calcium and other factors that cause volume depletion or alkalosis such as vomiting or thiazide use.^[7]

Causes

Currently, the main cause of milk-alkali syndrome is calcium carbonate consumption, mostly in postmenopausal women for osteoporosis prevention or treatment or in patients on glucocorticoid therapy (for example in organ transplantation), and chronic renal disease.^[8] With the introduction of histamine antagonists and decrease in antacid consumption since the 1970s, the incidence of milk-alkali syndrome has decreased significantly. However, since the 1990s, there has been an increase in milk-alkali syndrome mostly due to increase in calcium and vitamin D consumption in postmenopausal women for osteoporosis prevention.^[3]^[4]^[5]

Differentiating Milk-alkali syndrome from other Diseases

Milk-alkali syndrome should be differentiated from other disorders that cause hypercalcemia such as hyperparathyroidism, malignancies, hyperthyroidism, immobilization, sarcoidosis and some drugs (thiazides, vitamin D, lithium and vitamin A toxicity)^[9]

Risk Factors

Patients with the following conditions are more susceptible to milk-alkali syndrome: Older age, preexisting chronic renal disease, concurrent vomiting (bulimia nervosa or hyperemesis gravidarum ) and use of certain drugs like thiazide, NSAIDs, and ACE inhibitors.^[3]^[10]^[11]^[12]^[5]^[13]^[4]

Screening

There is insufficient evidence to recommend routine screening for milk-alkali syndrome.

Natural History, Complications and Prognosis

Most patients with milk-alkali syndrome are asymptomatic and may be incidentally diagnosed. Complications of milk-alkali syndrome may include: confusion, psychosis, renal insufficiency, pancreatitis, abnormalities in cardiac conduction, and metastatic calcification. Prognosis of milk-alkali syndrome is generally good and early diagnosis and treatment, with withdrawal of the offending agent and supportive therapy, usually resolve the symptoms and abnormalities in milk-alkali syndrome (hypercalcemia, alkalosis and renal insufficiency).^[9]^[8]^[3]^[14]^[15]^[3]^[8]^[16]^[17]

Epidemiology and Demographics

The exact incidence and prevalence of milk-alkali syndrome is not known.^[18] With the introduction of histamine antagonists and decrease in antacid consumption since the 1970s, the incidence of milk-alkali syndrome has decreased significantly. However, since the 1990s, there has been an increase in milk-alkali syndrome due to increase in calcium and vitamin D consumption in postmenopausal women for osteoporosis prevention.^[3]^[4]^[5] Milk-alkali syndrome is the third most common cause of hypercalcemia in hospitalized patients after primary hyperparathyroidism and malignancies.^[10]

Diagnosis

Diagnostic Study of Choice

Milk-alkali syndrome is diagnosed by a history of excessive calcium consumption, hypercalcemia, metabolic alkalosis and variable degrees of renal insufficiency. ^[3]

History and Symptoms

In patients with milk-alkali syndrome, there is a history of excessive calcium and absorbable alkali consumption.^[3] Symptoms of milk-alkali syndrome may inculde: dizziness, vertigo, confusion, apathy, nausea, vomiting, anorexia, distaste for milk, headache, anorexia, pruritus, polydipsia, polyuria, myalgia, tremor, psychosis, and abnormal calcifications (keratopathy, renal calcinosis).^[14]^[15]

Physical Examination

The following should be considered in the physical examination of milk-alkali syndrome: vertigo, confusion, apathy, nausea, vomiting, pruritus, polydipsia, polyuria, myalgia, tremor, psychosis, and abnormal calcifications (keratopathy, renal calcinosis).^[14]^[15]^[3]

Laboratory Findings

The following laboratory findings are usually seen in milk-alkali syndrome: hypercalcemia, metabolic alkalosis, variable degrees of renal insufficiency, low or normal phosphorus, low Vitamin D, and low PTH.^[8]^[3]^[19]^[4]

Electrocardiogram

Milk-alkali syndrome causes hypercalcemia and hypercalcemia may cause the following findings on electrocardiogram (ECG): shortened QT interval (the most common finding), shortened ST segment, PR prolongation, increased amplitude of QRS complex, decreased amplitude of T wave, T wave notching, transient ST segment elevation, bradycardia, sinus arrest, and ventricular arrhythmias.^[20]^[21]^[22]^[23]^[24]^[25]

X-ray

X-ray is not useful in the diagnosis of milk-alkali syndrome. However, X-ray may be useful in excluding other causes of hypercalcemia. Renal calcium deposits are not seen on X-ray in milk-alkali syndrome.^[3]

Echocardiography and Ultrasound

Echocardiography is not useful in the diagnosis of milk-alkali syndrome. Ultrasound is not useful in the diagnosis of milk-alkali syndrome. However, ultrasound may be helpful in excluding other causes of hypercalcemia.

CT Scan

CT scan is not useful in the diagnosis of milk-alkali syndrome. However, CT scan may be helpful in excluding other causes of hypercalcemia.

MRI

MRI is not useful in the diagnosis of milk-alkali syndrome. However, MRI may be helpful in excluding other causes of hypercalcemia.

Other Imaging Findings

There are no other imaging findings associated with milk-alkali syndrome.

Other Diagnostic studies

There are no other diagnostic studies associated with milk-alkali syndrome.

Treatment

Medical therapy

Treatment of milk-alkali syndrome is mostly supportive and mainly includes withdrawal of the offending agent, hydration and intravenous volume expansion. However, other treatments such as therapy with calcium supplements (in temporary hypocalcemia) and hemodialysis (in acute or chronic irreversible renal insufficiency) may be required.^[8]^[3]

Surgery

Surgical intervention is not recommended for the routine management of milk-alkali syndrome.

Primary Prevention

Effective measures for the primary prevention of milk-alkali syndrome includes public education about the potential adverse effects of calcium supplements. Calcium intake less than 2 g/daily is usually safe, however, 1.2 to 1.5 g/daily of calcium intake should be taken by individuals with risk factors for milk-alkali syndrome.^[3]^[10]^[11]^[12]^[5]^[13]^[4]

Secondary Prevention

There are no established measures for the secondary prevention of milk-alkali syndrome.

Cost-Effectiveness of Therapy

There is insufficient evidence about the cost-effectiveness of therapy in milk-alkali syndrome.

Future or Investigational Therapies

No further or investigational therapies have been suggested in milk-alkali syndrome.

 == Overview ==
-Milk-alkali syndrome (also known as calcium-alkali syndrome) is characterized by a history of excessive [[calcium]] intake and  [[hypercalcemia]], [[metabolic alkalosis]] and varying degrees of [[renal insufficiency]]. In 1915, Bertram Sippy introduced a treatment for [[Peptic ulcer|peptic ulcer disease]] which was an hourly mixture of milk and cream combined with [[Alkali|alkaline]] powders. In 1923, the toxic effects of Sippy’s regimen was reported for the first time. With the introduction of [[Histamine antagonist|histamine antagonists]] and decrease in [[antacid]] consumption since the 1970s, the incidence of milk-alkali syndrome has decreased significantly. However, since the 1990s, there has been an increase in milk-alkali syndrome due to increase in [[calcium]] and [[vitamin D]] consumption in postmenopausal women for [[osteoporosis]] prevention. Treatment of milk-alkali syndrome is mostly supportive and mainly includes withdrawal of the offending agent, hydration and [[Intravenous therapy|intravenous]] volume expansion. Prognosis of milk-alkali syndrome is generally good and early [[diagnosis]] and treatment, with withdrawal of the offending agent and supportive therapy, usually resolve the symptoms and abnormalities in milk-alkali syndrome ([[hypercalcemia]], [[alkalosis]] and [[renal insufficiency]]).
+Milk-alkali syndrome (also known as calcium-alkali syndrome) is characterized by a history of excessive [[calcium]] intake and  [[hypercalcemia]], [[metabolic alkalosis]] and varying degrees of [[renal insufficiency]]. In 1915, Bertram Sippy introduced a treatment for [[Peptic ulcer|peptic ulcer disease]] which was an hourly mixture of milk and cream combined with [[Alkali|alkaline]] powders. In 1923, the toxic effects of Sippy’s regimen were reported for the first time. With the introduction of [[Histamine antagonist|histamine antagonists]] and decrease in [[antacid]] consumption since the 1970s, the incidence of milk-alkali syndrome has decreased significantly. However, since the 1990s, there has been an increase in milk-alkali syndrome due to an increase in [[calcium]] and [[vitamin D]] consumption in postmenopausal women for [[osteoporosis]] prevention. Treatment of milk-alkali syndrome is mostly supportive and mainly includes the withdrawal of the offending agent, hydration, and [[Intravenous therapy|intravenous]] volume expansion. Prognosis of milk-alkali syndrome is generally good and early [[diagnosis]] and treatment, with the withdrawal of the offending agent and supportive therapy, usually resolve the symptoms and abnormalities in milk-alkali syndrome ([[hypercalcemia]], [[alkalosis]] and [[renal insufficiency]]).

 == Differentiating Milk-alkali syndrome from other Diseases ==
-Milk-alkali syndrome should be differentiated from other disorders that cause hypercalcemia such as: hyperparathyroidism, malignancies, hyperthyroidism, immobilization, sarcoidosis and some drugs (thiazides, vitamin D, lithium and vitamin A toxicity)<ref name="Ali Patel 2020" />
