Reduce risk

1. Smoking cessation

Smoking accelerates lung function decline in patients with alpha-1-antitrypsin (A1AT) deficiency (also known as alpha-1)1

Mean annual decline in FEV1 in 208 never-smokers, 697 ex-smokers, and 22 current smokers with severe alpha-1.1

Why is smoking cessation so important?

  • Smokers with even 1 deficient allele are at increased risk of developing COPD2
  • Smoking is also the most important risk factor for the development of emphysema in alpha-1 patients with the Pi ZZ allele3
  • Smoking is a key factor in determining the extent of lung involvement in alpha-1. When compared to ex-smokers or non-smokers, smokers with alpha-1 related emphysema have3
    • Greater lung function decline (FEV1)
    • Higher mortality rates
  • Alpha-1 patients (FEV1 <50%) who quit smoking had a better survival rate than patients who continued to smoke4

2. Reduce other exposures3,5,6

Patients with alpha-1 should avoid persistent exposure to hazardous respiratory environments that can cause respiratory irritation.

  • This includes exposure to household and occupational dusts, fumes, and gases and to indoor and outdoor air pollutants
  • Avoidance of exposure should be taken into account when choosing an occupation

3. Immunize3,5

To prevent infection, the following vaccinations are recommended for alpha-1 patients with COPD:

  • Pneumococcal vaccination: recommended for COPD patients ≥65, and younger COPD patients with certain comorbid conditions; shown to reduce the incidence of community-acquired pneumonia in COPD patients younger than 65 with a predicted FEV1 <40%
  • Influenza vaccination: shown to reduce the risk of serious illness (such as serious lower respiratory tract infections) and death in patients with COPD

Smoking cessation is the most important preventive measure in the development of lung disease. Secondhand smoke should also be avoided5,6

Like smoking cessation, avoidance of exposure to hazardous respiratory environments may improve the prognosis of patients with alpha-13,5

Important safety information

PROLASTIN®-C (alpha1-proteinase inhibitor [human]) is indicated for chronic augmentation and maintenance therapy in adults with clinical evidence of emphysema due to severe hereditary deficiency of alpha1-PI (alpha1-antitrypsin deficiency).

The effect of augmentation therapy with any alpha1-proteinase inhibitor (alpha1-PI), including PROLASTIN-C, on pulmonary exacerbations and on the progression of emphysema in alpha1-antitrypsin deficiency has not been conclusively demonstrated in randomized, controlled clinical trials. Clinical data demonstrating the long-term effects of chronic augmentation or maintenance therapy with PROLASTIN-C are not available.

PROLASTIN-C is not indicated as therapy for lung disease in patients in whom severe alpha1-PI deficiency has not been established.

PROLASTIN-C is contraindicated in IgA-deficient patients with antibodies against IgA due to the risk of severe hypersensitivity and in patients with a history of anaphylaxis or other severe systemic reactions to alpha1-PI.

Hypersensitivity reactions, including anaphylaxis, may occur. Monitor vital signs and observe the patient carefully throughout the infusion. Should hypersensitivity symptoms be observed, promptly stop infusion and begin appropriate therapy. Have epinephrine and other appropriate therapy available for the treatment of any acute anaphylactic or anaphylactoid reaction.

PROLASTIN-C may contain trace amounts of IgA. Patients with known antibodies to IgA, which can be present in patients with selective or severe IgA deficiency, have a greater risk of developing potentially severe hypersensitivity and anaphylactic reactions.

The most common drug-related adverse reaction observed at a rate of >5% in subjects receiving PROLASTIN-C was upper respiratory tract infection. The most serious adverse reaction observed during clinical trials with PROLASTIN-C was an abdominal and extremity rash in 1 subject.

Because PROLASTIN-C is made from human plasma, it may carry a risk of transmitting infectious agents, eg, viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent. This also applies to unknown or emerging viruses and other pathogens.
