PDE4 inhibition in COPD

From “ThinkCOPDDifferently”:

The inhibition of PDE4 as a new approach in the treatment of COPD has been discussed and investigated by the medical community for many years. The crucial role of PDE4 in COPD-specific inflammation makes it a very interesting target.

New England Journal of Medicine:


These results show that, in patients with moderate-to-very-severe COPD, tiotropium is more effective than salmeterol in preventing exacerbations. (Funded by Boehringer Ingelheim and Pfizer; number, NCT00563381.)


Mode of action

Tiotropium is a muscarinic receptor antagonist, often referred to as an antimuscarinic or anticholinergic agent. Although it does not display selectivity for specific muscarinic receptors, on topical application it acts mainly on M3 muscarinic receptors[1] located on smooth muscle cells and submucosal glands not to produce smooth muscle contraction and mucus secretion, thus producing a bronchodilatory effect.

Westermark sign


The Westermark is an eponym indicating the abrupt cutoff of pulmonary vascularity distal to a large central pulmonary embolus. The presumed mechanism behind the image arises from the nearly complete obstruction of bloodflow to the pulmonary artery distal to the embolic clot.Presumably the lack of flow to these more distal vessels results in their radiographic transparency and an appearance of an abrupt truncation as is shown in this exemplary case.

The history is important for distinguishing methemoglobinemia between cyanosis that is due to cardiopulmonary abnormalities and that from other causes of discoloration of the skin and mucous membranes. Acute methemoglobinemia can be life threatening and usually is due to toxic exposure or drugs. Therefore, obtaining a history of exposure to substances that can induce methemoglobinemia is important. In contrast, patients with hereditary methemoglobinemia are often asymptomatic despite the presence of cyanosis. The failure of 100% oxygen to correct cyanosis is suggestive of methemoglobinemia.

Symptoms are proportional to the level of methemoglobin.

  • Less than 10% methemoglobin – No symptoms
  • 10-20% methemoglobin – Skin discoloration only (most notably on mucus membranes)
  • 20-30% methemoglobin – Anxiety, headache, dyspnea on exertion
  • 30-50% methemoglobin – Fatigue, confusion, dizziness, tachypnea, palpitations
  • 50-70% methemoglobin – Coma, seizures, arrhythmias, acidosis
  • Greater than 70% methemoglobin – Death

More Information

Mediastinoscopy is the ‘gold standard’ method for determining the presence of nodal metastases in the mediastinum. Generally performed as an outpatient surgical procedure, it is associated with a low rate of serious adverse effects (<1%) and the procedure is highly accurate, with false negative rates reported to be between 6% and 9%. Endobronchial ultrasound (EBUS) guided fine needle aspiration biopsy of mediastinal nodes offers a less invasive alternative for histologic sampling of the mediastinal nodes. The procedure has been widely adopted by pulmonologists and is poised to replace mediastinoscopy in the future. For thoracic surgeons, the technique can be easily learned and it may be important to do so if our specialty is to maintain its traditional and important role in the diagnosis and staging of thoracic malignancies.
