Overview
If left untreated, [#]% of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
OR
Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].
OR
Prognosis is generally excellent/good/poor, and the 1/5/10-year mortality/survival rate of patients with [disease name] is approximately [#]%.
Natural History, Complications, and Prognosis
Natural History
- The symptoms of (disease name) usually develop in the first/ second/ third decade of life, and start with symptoms such as ___.
- The symptoms of (disease name) typically develop ___ years after exposure to ___.
- If left untreated, [#]% of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
Complications
- Common complications of [disease name] include:
- [Complication 1]
- [Complication 2]
- [Complication 3]
Prognosis
- Prognosis of HP is generally excellent.
- Total lung recovery occurs in most cases but may take several years.[1]
- Surgical lung biopsy can be done to check for fibrosis which is an indicator of poor prognosis.[2]
- Prediction of prognosis can be done using high resolution CT scan.[3]
- A study done among old patients suffering from HP with no signs of air trapping on CT scan but desaturation with exercise showed poor survival rates.[4]
