Many of these earlier studies were based on the hypothesis that IPF is an inflammatory disorder. Pirfenidone
A Cochrane review comparing pirfenidone with placebo, found a reduced risk of disease progression by 30%. FVC or VC was also improved, even if a mild slowing in FVC decline could be demonstrated only in one of the two CAPACITY trials. A third study, which was completed in 2014 found reduced decline in lung function and IPF disease progression. The data from the ASCEND study were also pooled with data from the two CAPACITY studies in a pre-specified analysis which showed that pirfenidone reduced the risk of death by almost 50% over one year of treatment. N-acetylcysteine and triple therapy
N-Acetylcysteine (NAC) is a precursor to glutathione, an antioxidant. It has been hypothesized that treatment with high doses of NAC may repair an oxidant–antioxidant imbalance that occurs in the lung tissue of patients with IPF. In the first clinical trial of 180 patients (IFIGENIA), NAC was shown in previous study to reduce the decline in VC and DLCO over 12 months of follow-up when used in combination with prednisone and azathioprine (triple therapy).More recently, a large randomized, controlled trial (PANTHER-IPF) was undertaken by the National Institutes of Health (NIH) in the US to evaluate triple therapy and NAC monotherapy in IPF patients.
Many of them, however, are specific for a certain cause of orthostatic hypotension, e.g. maintaining a proper fluid intake in dehydration. Orthostatic hypercoagulability
Prolonged still standing significantly activates the coagulation cascade, called orthostatic hypercoagulability. Overall, it causes an increase in transcapillary hydrostatic pressure. As a result, approximately 12% of blood plasma volume crosses into the extravascular compartment. This plasma shift causes an increase in the concentration of coagulation factors and other proteins of coagulation, in turn causing hypercoagulability. Orthostatic tremor
Characterized by fast (12–18 Hz) rhythmic muscle contractions that occur in the legs and trunk immediately after standing. No other clinical signs or symptoms are present and the shaking ceases when the patient sits or is lifted off the ground. The high frequency of the tremor often makes the tremor look like rippling of leg muscles while standing. Long-term complications
Standing per se does not pose any harm. In the long term, however, complications may arise. See also
