Pseudohypoparathyroidism type 1A Hiperparatirooidismo is a type of pseudohypoparathyroidism PHP; see this term characterized by renal resistance to parathyroid hormone PTHresulting in hypocalcemia, hyperphosphatemia, and elevated PTH; resistance to other hormones including thydroid stimulating hormone TSHgonadotropins and growth-hormone-releasing hiperparatiroldismo GHRH ; and a constellation of clinical features known as Albright hereditary osteodystrophy AHO; see this term.

Onset of endocrine symptoms occurs during childhood, although cases with severe hypothyroidism at neonatal screening have been reported. Patients present with varying degrees of AHO features including obesity.

Ectopic ossifications may range from absent to extensive and generate severe pain. Developmental delay is highly variable, even in families with the same mutation. PTH resistance is not typically present at birth but develops over time, in some patients from a few months of age.

Other symptoms related to hypocalcemia include: Mild TSH resistance is often present at birth and may be diagnosed through neonatal screening of congenital hypothyroidism see this term. It is usually asymptomatic. Hormone resistance may develop over time, up until late adulthood.

Rheumatologic complications have also been reported. The evolution of bone mineralization remains unclear.

In a subset of patients negative for these mutations, methylation defects at the same locus have been reported. After infusion of biosynthetic PTH which may be useful in difficult casesnephrogenic cAMP and urinary excretion of phosphate do not increase. AHO is diagnosed both clinically and on Hiperpagatiroidismo, showing typical shortening of the 4th metacarpal. Diagnosis is confirmed by genetic testing.

Differential diagnoses include primary hypothyroidism, secondary hyperparathyroidism due to vitamin D deficiency, and other types of PHP.

Hiperparatiroidiwmo is autosomal dominant with parental imprinting. Resistance to hormones develops only after maternal inheritance. In cases where methylation defects are found, genetic counseling may be difficult or impossible.

Treatment is based on maintaining normocalcemia and, when possible, normalizing serum levels of PTH, with an active form of vitamin D alfacalcidol or calcitriol and calcium supplementation.

Associated endocrinopathies should be treated when present particularly hypothyroidism, growth hormone deficiency and hypogonadism with levothyroxine and sex hormones. GH replacement therapy should be started as soon as possible.

There is no treatment for AHO. With proper treatment, prognosis is good, but quality of life may be affected by subcutaneous ossifications and the presence of severe short stature and obesity. Life expectancy is normal provided that endocrine disorders are correctly treated. Other search option s Alphabetical list. Summary and related texts.

Clinical description Onset of endocrine symptoms occurs during childhood, although cases with severe hypothyroidism at neonatal screening have been reported.

Differential diagnosis Differential diagnoses include primary hypothyroidism, secondary hyperparathyroidism due to vitamin Hipoparatiroidisko deficiency, and other types of PHP. Antenatal diagnosis Antenatal diagnosis is possible when a disease causing mutation in the family is known.

Genetic counseling Transmission is autosomal dominant with parental imprinting. Management and treatment Treatment is based on maintaining normocalcemia and, when possible, normalizing serum levels of PTH, with an active form of vitamin D alfacalcidol or calcitriol and calcium supplementation.

Prognosis With proper treatment, prognosis is good, but quality of life may be affected by subcutaneous ossifications and the presence of severe short stature and obesity.
