⚡ Quick Start — If You Read Nothing Else
The 8 most important things to know right now.
- Alpha-1 is a genetic condition, not just a lung disease. It is caused by mutations in the SERPINA1 gene that result in low levels of alpha-1 antitrypsin (AAT) protein, which normally protects the lungs from damage. It can also cause liver disease because abnormal AAT protein accumulates in liver cells.
- It is massively underdiagnosed. An estimated 100,000 Americans have severe AATD, but only about 10,000 have been diagnosed. The average patient sees 3 or more doctors over 5–7 years before getting the correct diagnosis. If you have early-onset COPD or emphysema, get tested.
- A simple blood test can diagnose it. An AAT serum level plus genotyping (or a free home test kit from the Alpha-1 Foundation) is all it takes. Testing should be done once in a lifetime for anyone with COPD, unexplained liver disease, or a family history of Alpha-1.
- Augmentation therapy is the only disease-specific treatment for lung disease. Weekly IV infusions of pooled human AAT protein (Prolastin-C, Zemaira, Aralast NP, Glassia) slow the progression of emphysema. It does not reverse existing damage, but it can meaningfully slow decline.
- Standard COPD care still applies. Bronchodilators, inhaled corticosteroids (when appropriate), pulmonary rehabilitation, vaccinations, and smoking cessation are essential alongside augmentation therapy.
- Smoking is catastrophically harmful for Alpha-1 patients. Smoking accelerates lung destruction dramatically in AATD. If you smoke, stopping is the single most important thing you can do. Even secondhand smoke and occupational exposures should be avoided.
- Liver disease requires separate monitoring. About 10–15% of adults with the ZZ genotype develop significant liver disease. Liver function tests should be checked regularly, and hepatology referral is needed if abnormalities arise. Liver transplant is curative for Alpha-1 liver disease.
- Promising new therapies are in development. RNA interference (fazirsiran), gene therapy, neutrophil elastase inhibitors, and other approaches are in clinical trials. The treatment landscape may change significantly in the coming years.
📅 Your First-Year Action Clock
Alpha-1 is a marathon, but the first year sets the trajectory. Here is a dated checklist — from confirming the diagnosis, to the single most important intervention (stopping all smoke exposure), to treatment decisions, lung and liver surveillance, and testing your family. Bring the scripts below to your appointments.
- Absolute, permanent smoking and vaping cessation is the overriding “stop” in Alpha-1. There is no safe amount of smoking, vaping, cannabis smoke, or secondhand smoke, because each one accelerates irreversible lung destruction far faster in Alpha-1 than in the general population. If you change only one thing, stop inhaling smoke of any kind.
- During an augmentation infusion, know when to stop: hives, wheezing, chest tightness, facial or lip swelling, fever, chills, or lightheadedness can signal an infusion or allergic reaction. Tell the nurse to slow or stop the infusion and get help; severe reactions are rare but require stopping immediately.
- Liver red flags — same-day care: yellowing of the eyes or skin (jaundice), a swelling belly or legs, confusion, or vomiting blood can mean advancing liver disease. Alpha-1 harms the liver too, and augmentation therapy does not treat the liver, so the liver is monitored and acted on separately.
- When to ask about transplant: if breathing and lung function keep worsening despite maximal treatment (for example FEV1 falling toward 25–30% predicted), ask about lung transplant evaluation; for advanced liver disease, ask about liver transplant, which is curative for the Alpha-1 liver problem.
- Within the first week of diagnosis: make sure your diagnosis is complete — it needs both a serum AAT level and a SERPINA1 genotype (for example Pi*ZZ, Pi*SZ, or Pi*Z/Null), not just one. Ask: "What is my exact genotype and my serum AAT level in mg/dL, and am I below the 57 mg/dL protective threshold?" Request a pulmonology referral, and a hepatology referral if any liver enzymes are abnormal.
- In the first month — the single most important step: stop all smoking and vaping. Smoking accelerates Alpha-1 emphysema roughly two- to three-fold, so complete tobacco, vape, and cannabis-smoke cessation — plus avoiding secondhand smoke and occupational lung irritants — is the one action that changes your future the most. Ask: "Can you start me on a quit plan today — varenicline, bupropion, or nicotine replacement — and connect me with the free 1-800-QUIT-NOW coaching?"
- By month 3 — COPD treatment and the augmentation decision: confirm you are on guideline-based inhalers, pulmonary rehabilitation, and vaccinations, and settle whether augmentation therapy is right for you. Ask: "Based on my genotype and my FEV1, am I a candidate for augmentation therapy, and what would my insurance coverage and out-of-pocket cost be?"
- By month 6, then every 6–12 months — lung and liver surveillance: spirometry (FEV1) tracks the lungs; liver function tests (AST, ALT, bilirubin, albumin) at least once a year track the liver, because the misfolded Z protein builds up in liver cells. If cirrhosis is present, guidelines advise a liver ultrasound every 6 months to screen for liver cancer.
- Family testing — do not skip this: because Alpha-1 is inherited, first-degree relatives (parents, siblings, children) should be tested once in a lifetime. Ask: "Can you help arrange free Alpha-1 testing for my siblings and children through the Alpha-1 Foundation ACT Study?"
Understanding Alpha-1 Antitrypsin Deficiency
Alpha-1 antitrypsin deficiency (AATD, also called Alpha-1 or AAT deficiency) is a genetic condition that increases the risk of lung disease and liver disease. It is one of the most common serious hereditary conditions in people of European descent, yet it remains severely underdiagnosed.
The condition is caused by mutations in the SERPINA1 gene, which provides instructions for making a protein called alpha-1 antitrypsin (AAT). This protein is produced mainly in the liver and released into the bloodstream, where it travels to the lungs to protect them from damage caused by neutrophil elastase — an enzyme released by white blood cells during normal immune responses and especially during infections.
When AAT levels are too low, neutrophil elastase attacks lung tissue unchecked, gradually destroying the tiny air sacs (alveoli) and leading to emphysema. In some genotypes, the abnormal AAT protein also folds incorrectly and gets stuck inside liver cells, causing liver inflammation, fibrosis, and potentially cirrhosis.
Key Breakthroughs in Alpha-1
While Alpha-1 research has historically moved more slowly than some other fields, several important advances have changed patient care or are poised to do so:
Diagnosis: Getting Tested for Alpha-1
The ATS/ERS guidelines recommend that all adults with COPD, non-responsive asthma, unexplained liver disease, necrotizing panniculitis, or a family history of Alpha-1 should be tested. Testing is simple and needs to be done only once in a lifetime.
Genotypes — What They Mean
Alpha-1 is inherited in an autosomal co-dominant pattern. Each person carries two copies of the SERPINA1 gene — one from each parent. The combination determines AAT production and disease risk.
| Genotype | AAT Level | Lung Risk | Liver Risk | What This Means |
|---|---|---|---|---|
| Pi*MM | Normal (100–300 mg/dL) | None | None | Normal. No Alpha-1 related risk. |
| Pi*MZ | Mildly reduced (~60% of normal) | Slight increase, especially in smokers | Minimal | Carrier. Generally healthy. Avoid smoking. About 3–5% of COPD patients carry MZ. |
| Pi*SZ | Moderately reduced (~35–40% of normal) | Moderate, especially if smoking | Low | Moderate deficiency. May develop emphysema, especially with smoking exposure. |
| Pi*ZZ | Severely reduced (~10–15% of normal, typically <57 mg/dL) | High | Significant (10–15% of adults develop cirrhosis) | Severe deficiency. Most common genotype requiring augmentation therapy. Both lung and liver risk. |
| Pi*Null/Null or Pi*Z/Null | Undetectable or very low | Very high | Low (no misfolded protein produced in Null/Null) | Rarest. Highest emphysema risk. Null alleles produce no AAT at all, so no liver polymerization in Null/Null. |
Lung Disease in Alpha-1
The primary lung manifestation of AATD is emphysema — specifically, panacinar (panlobular) emphysema that often begins in the lower lobes. This differs from the centrilobular, upper-lobe-predominant emphysema typically seen in smokers without Alpha-1. Many patients also develop features of chronic bronchitis, bronchiectasis, or an asthma-like component.
Augmentation Therapy — The Disease-Specific Treatment
Augmentation therapy (also called replacement therapy or IV AAT therapy) is the only FDA-approved treatment that directly addresses the underlying protein deficiency in Alpha-1 lung disease. It involves weekly intravenous infusions of purified AAT protein derived from pooled human plasma.
Standard COPD Management in Alpha-1
In addition to augmentation therapy, Alpha-1 patients with lung disease should receive all standard COPD treatments recommended by GOLD guidelines. These medications and strategies improve symptoms and quality of life even though they do not address the underlying AAT deficiency.
💬 Word-for-Word Scripts for Every Appointment
Alpha-1 visits are short and the disease is rare, so many doctors have seen only a handful of cases. The single highest-value thing you can do is walk in with the exact questions that move your care forward. Copy these word-for-word. They are written to get you a number, a decision, or a referral — not a vague reassurance.
At diagnosis
- Ask: "What is my exact SERPINA1 genotype (for example Pi*ZZ, Pi*SZ, Pi*Z/Null), and what was my serum AAT level in mg/dL?"
- Ask: "Am I below the 57 mg/dL (11 micromol/L) protective threshold?"
- Ask: "Was my AAT level drawn when I was well, or during an infection when it can read falsely high?"
- Ask: "Can you refer me to a pulmonologist, and to a hepatologist if any of my liver enzymes are abnormal?"
- Ask: "Should I have a baseline chest CT to see whether I already have emphysema, and where it is in the lungs?"
Stopping smoke exposure — the highest-value visit
- Ask: "Can you start me on a quit-smoking medicine today — varenicline, bupropion, or nicotine replacement — and refer me to 1-800-QUIT-NOW coaching?"
- Ask: "Which quit medicine is safest for me given my lung and liver status, and what dose do I start at?"
- Ask: "Does my plan cover cessation medicines and counseling at no cost, as most plans are required to?"
Deciding on augmentation therapy
- Ask: "Based on my genotype and my FEV1, am I a candidate for augmentation therapy right now, or should we watch and re-test?"
- Ask: "Which product would you use (Prolastin-C, Zemaira, Aralast NP, or Glassia), and can I do the 60 mg/kg weekly infusion at home?"
- Ask: "What will my out-of-pocket cost be under my plan, and can you connect me to AlphaNet and the manufacturer copay program?"
- Ask: "How will we measure whether it is working — how often will I get spirometry and CT?"
Protecting the liver
- Ask: "How often will you check my liver panel (AST, ALT, bilirubin, albumin, INR), and have I had a FibroScan?"
- Ask: "Do I have any liver scarring now, and if I do, should I have a liver ultrasound every 6 months to screen for cancer?"
- Ask: "Since augmentation does not treat the liver, is a liver-directed trial such as fazirsiran appropriate for me?"
Family and genetics
- Ask: "Which of my relatives should be tested, and can you help arrange free Alpha-1 Foundation ACT Study kits for them?"
- Ask: "Would genetic counseling help us understand the risk to my children?"
- Ask: "If my partner and I are both carriers, what are our options before or during pregnancy?"
Trials, worsening disease, and transplant
- Ask: "Are there clinical trials open to me right now for my genotype and stage, at an Alpha-1 Clinical Resource Center?"
- Ask: "At what FEV1 or symptom level should we start talking about lung transplant evaluation?"
- Ask: "If my liver disease advances, when do we refer to a liver transplant center?"
💊 Medications, Doses, and What Each One Does
These are the medicines used in Alpha-1 lung disease and the exposures that drive it. Doses below are the usual adult starting doses from FDA prescribing information and the GOLD 2026 COPD report; your own dose is set by your doctor. Nothing here is a prescription — bring it to your clinician and use the scripts above.
Augmentation therapy (the only Alpha-1-specific lung treatment)
- Prolastin-C, Zemaira, Aralast NP, Glassia: all dosed at 60 mg/kg intravenously once weekly per FDA prescribing information. The lyophilized products (Prolastin-C, Zemaira, Aralast NP) infuse in roughly 15 minutes; Glassia is a ready-to-use liquid infused over about 60–80 minutes. The goal is to keep the trough AAT level at or above 57 mg/dL (11 micromol/L).
Long-acting inhalers (LABA/LAMA) — the COPD backbone
- Tiotropium (LAMA): 18 mcg inhaled once daily (HandiHaler) or 2.5 mcg Respimat, 2 inhalations once daily, per label.
- Umeclidinium (LAMA): 62.5 mcg inhaled once daily, per label.
- Umeclidinium/vilanterol (LAMA/LABA): 62.5/25 mcg once daily, per prescribing information.
- Tiotropium/olodaterol (LAMA/LABA): 2.5/2.5 mcg, 2 inhalations once daily, per label.
Inhaled corticosteroids (added when eosinophils are high or exacerbations recur)
- Budesonide/formoterol (ICS/LABA): 160/4.5 mcg, 2 inhalations twice daily, per label.
- Fluticasone furoate/umeclidinium/vilanterol (triple therapy): 100/62.5/25 mcg once daily, per prescribing information. GOLD 2026 reserves ICS-containing regimens for higher eosinophil counts or frequent exacerbations.
Rescue and add-on drugs
- Albuterol (rescue SABA): 90 mcg per actuation, 2 puffs every 4–6 hours as needed, per label.
- Roflumilast (Daliresp, PDE4 inhibitor): 500 mcg by mouth once daily for severe COPD with chronic bronchitis, per label.
- Azithromycin (chronic, exacerbation prevention): 250 mg daily or 500 mg three times weekly in selected patients; monitor hearing and QTc.
Smoking-cessation medicines (the highest-value prescriptions in Alpha-1)
- Varenicline: 0.5 mg daily for 3 days, then 0.5 mg twice daily for 4 days, then 1 mg twice daily, per label.
- Bupropion SR: 150 mg each morning for 3 days, then 150 mg twice daily, per label.
- Nicotine patch: 21 mg per 24 hours to start for heavier smokers, stepping down to 14 mg then 7 mg; short-acting nicotine gum or lozenge 2 mg or 4 mg for breakthrough cravings.
Exacerbation (flare) medicines
- Prednisone: 40 mg by mouth once daily for 5 days is a common COPD-exacerbation course, per GOLD 2026.
- Antibiotics for purulent flares: amoxicillin-clavulanate 875 mg twice daily, or doxycycline 100 mg twice daily, typically for 5–7 days.
Using medicines safely when the liver is involved
- Acetaminophen: keep total below 2 g per day if you have Alpha-1 liver disease, and avoid it entirely in acute liver failure.
- Alcohol: avoid entirely if you have any liver enzyme elevation or fibrosis, because it stacks with the AAT-polymer injury already stressing the liver.
Simple numeric stop rules to remember
- When to stop an infusion: stop if you develop hives, wheeze, throat or lip swelling, chest tightness, or lightheadedness during augmentation — tell the nurse to stop and get help.
- Discontinue if directed after transplant: augmentation is normally stopped after a successful lung or liver transplant that restores normal AAT levels — do not stop it on your own before then.
- When to stop and call the same day: stop routine activity and seek same-day care if you turn yellow (jaundice), vomit blood, or become confused — these are liver red flags.
- Trial period for add-on drugs: if an inhaler or add-on such as roflumilast causes intolerable side effects, ask your doctor about a defined trial period and when to stop it.
Doses reflect FDA prescribing information and the GOLD 2026 report as of July 2026. Confirm every dose with your own clinician and pharmacy.
🔗 What Works Together (and What Cancels It Out)
In Alpha-1, no single treatment does everything. The gains come from stacking a few interventions whose benefits combine — and from removing the one exposure that cancels all of them out.
Smoking cessation amplifies every other treatment
Stopping all smoke exposure is not just one item on the list — it is the multiplier. Augmentation therapy, inhalers, and pulmonary rehab all slow decline, but continued smoking accelerates lung destruction 2–3 fold and cancels much of that benefit. Cessation is the synergy that makes the rest of the plan pay off.
Augmentation plus rehab plus vaccination
Augmentation therapy slows tissue loss on CT, pulmonary rehabilitation improves what you can do with the lungs you have, and vaccination prevents the infections that trigger the neutrophil-elastase surges that damage lung tissue. Used together the effect is additive: fewer flares, preserved function, better day-to-day capacity. Ask: "Am I getting all three — augmentation if eligible, a rehab referral, and my flu, pneumococcal, COVID-19, and RSV vaccines?"
The liver-and-lung combination on the horizon
Because augmentation does nothing for the liver, the emerging strategy for Pi*ZZ patients with both problems is a combination: a liver-directed medicine such as fazirsiran (RNAi) to cut Z-AAT polymer production, paired with augmentation to keep the lungs protected while blood AAT falls. This dual-target stacking is being studied and may define future care. Ask: "If I ever go on a liver-targeted therapy, will I also need augmentation to protect my lungs?"
What cancels benefit
Secondhand smoke, vaping, cannabis smoke, wood smoke, and untreated respiratory infections each work against the whole plan. Alcohol combined with Alpha-1 liver disease is a similar negative synergy on the liver side. Removing these is as valuable as adding a drug.
Supportive & Lifestyle Care
Liver Disease in Alpha-1
Liver disease in Alpha-1 is caused by a mechanism distinct from the lung disease. In the Z mutation, the AAT protein misfolds and polymerizes within liver cells (hepatocytes), forming insoluble aggregates that cannot be secreted into the bloodstream. These polymer inclusions trigger chronic inflammation, hepatocyte injury, fibrosis, and can eventually lead to cirrhosis.
Pregnancy, Fertility & Family Planning
Alpha-1 antitrypsin deficiency is inherited in an autosomal co-dominant pattern through the SERPINA1 gene: everyone carries two copies, and you inherit one from each parent. The most common severe form is the ZZ genotype; people with one Z copy (MZ) are carriers who are usually healthy. If both partners carry a Z (or other deficiency) allele, each pregnancy has a 25% chance of a child with two deficiency alleles.
- Genetic counseling and partner testing. If you have AATD or a family history, genetic counseling before pregnancy is recommended, and your partner can be tested for SERPINA1 deficiency alleles to clarify the risk to children. Prenatal testing and, for some families, preimplantation genetic testing (PGT) with IVF are options to discuss. Cascade testing of close relatives is also recommended.
- Pregnancy is usually well tolerated in women with AATD, and the most important factor for a healthy pregnancy is preserved lung function. Not smoking — and avoiding all secondhand smoke — is the single most important thing you can do, because smoking dramatically accelerates Alpha-1 lung damage.
- Augmentation therapy in pregnancy. There is only limited data on IV augmentation therapy during pregnancy. The decision to continue or pause it is individualized with your Alpha-1 specialist based on your lung disease; pregnancy registries help inform this. Do not start or stop it on your own.
- Diagnosis during pregnancy. AAT is an “acute-phase” protein, so blood levels can rise in pregnancy and may look falsely reassuring — genetic (genotype) testing, not the level alone, should be used to confirm or exclude AATD.
- Liver and the newborn. Women with Alpha-1 liver disease should be co-managed by hepatology. A baby who inherits two deficiency alleles (e.g., ZZ) can occasionally develop newborn jaundice/cholestasis and should have pediatric follow-up; breastfeeding is generally encouraged. A maternal-fetal medicine (high-risk obstetrics) specialist should co-manage if you have significant lung or liver disease.
- Should my partner be tested, and would genetic counseling help us understand the risk to our children?
- If I become pregnant, will I continue augmentation therapy, and how will my breathing be monitored?
- What lung-function tests should I have before and during pregnancy?
- If our baby inherits Alpha-1, what newborn liver checks are needed?
Emerging Therapies
The Alpha-1 treatment pipeline has expanded significantly in recent years. Several approaches aim to address limitations of current augmentation therapy or target the liver disease mechanism for the first time.
Clinical Trials — Finding and Enrolling
Because Alpha-1 is a rare disease, clinical trials are especially important. Every patient who enrolls contributes to knowledge that can improve treatment for the entire Alpha-1 community. The Alpha-1 Foundation actively tracks and promotes awareness of trials for AATD.
International Access & Regulatory Landscape
Access to augmentation therapy and other Alpha-1 treatments varies significantly by country.
Failed & De-Adopted Therapies
Knowing what has been tried and did not work is important for evaluating new options and avoiding treatments that have already been studied and found ineffective.
Specialty Centers
Alpha-1 is best managed by physicians with experience in this specific genetic condition. The Alpha-1 Foundation has designated Clinical Resource Centers (CRCs) at academic medical centers across the country that provide expert multidisciplinary care.

Caregiver Guidance
Alpha-1 is a chronic, lifelong condition that affects not just the patient but the entire family. Because it is genetic, the diagnosis often impacts multiple family members simultaneously.
💰 What It All Costs — and How It Gets Paid
Money is the barrier patients hit most often, so here are real numbers with their sources and dates. These are planning figures, not a personal quote — your out-of-pocket cost depends entirely on your insurance. The pattern to notice: the single most valuable intervention (stopping smoke exposure) is also the cheapest.
Augmentation therapy — the big number
- A peer-reviewed US insurance-claims analysis (Sieluk et al., Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, 2018) found augmentation therapy averaged about $82,002 per year in drug cost, with total yearly medical costs around $127,537 for people on augmentation versus about $15,874 for those not on it (2017 dollars; real prices today are higher).
- On a per-infusion basis the average wholesale cost runs roughly $3,000–$5,000 per weekly infusion, which is why the yearly total commonly lands between $100,000 and $150,000.
- How it is billed: augmentation is almost always covered under your major-medical benefit (like an in-office infusion) and, for people on Medicare, under Part B — not the pharmacy benefit. Prior authorization confirming a Pi*ZZ, Pi*Z/Null, or Null genotype plus airflow obstruction is nearly always required.
- Assistance path: each manufacturer runs a copay and patient-assistance program — Grifols (Prolastin-C), CSL Behring (Zemaira), and Takeda (Aralast NP, Glassia). AlphaNet (alphanet.org) coordinates disease management and copay navigation; the Alpha-1 Foundation (1-877-228-7321) can direct uninsured patients toward assistance.
Smoking-cessation medicines — a rounding error by comparison
- Generic varenicline runs roughly $35–$40 for a month’s supply with a GoodRx discount (GoodRx estimate, July 2026); generic bupropion SR is often $10–$20 per month; nicotine patches run about $25–$45 per month over the counter.
- The national Quitline (1-800-QUIT-NOW) coaching is free, and under the Affordable Care Act most plans must cover cessation medicines and counseling at $0.
Inhalers, monitoring, and testing
- Brand-name LABA/LAMA and triple-therapy inhalers commonly list around $400–$600 per month retail before insurance and coupons; generic azithromycin for exacerbation prevention is roughly $15 per month.
- A FibroScan (liver stiffness test) typically runs about $100–$300; commercial SERPINA1 genetic testing runs roughly $150–$300, but the Alpha-1 Foundation ACT Study provides genotype and level testing for free.
Transplant — the catastrophic-cost tier
- Published US billed-charge estimates put a lung transplant near $1,200,000 and a liver transplant near $800,000–$1,000,000 in the first year including evaluation, surgery, and follow-up (Milliman Research Report estimates). These are almost always handled through insurance and transplant-center financial coordinators, not out of pocket.
- Stop the infusion if you develop hives, wheeze, throat or lip swelling, or lightheadedness — these can signal a reaction.
- Same-day liver check: if a liver enzyme (AST or ALT) stays above 2 times the upper limit of normal on repeat testing, that is the trigger for hepatology referral.
- Transplant conversation: when FEV1 falls toward 25–30% predicted despite maximal therapy, that is the number that should open a lung-transplant evaluation.
- Cancer screening: once cirrhosis is present, a liver ultrasound every 6 months is the standard screening interval (AASLD).
Cost figures as of July 2026 and are illustrative, not quotes. Augmentation figures are 2017-dollar claims data and represent a floor. Confirm your own price and coverage with your insurer and specialty pharmacy.

What This Guide Does Not Know
An honest guide names its own limits:
- This guide cannot diagnose, treat, or predict outcomes for any individual. It does not know your genotype, AAT level, lung function, liver status, or personal circumstances. Only your medical team can create your specific care plan.
- Alpha-1 research is evolving. New trial results, drug approvals, and guideline updates occur over time. Every time-sensitive fact should be re-verified with your medical team, on ClinicalTrials.gov, and through the Alpha-1 Foundation.
- Drug availability varies by country. This guide focuses primarily on FDA-approved therapies. Access to augmentation therapy and emerging treatments differs significantly in Europe, Canada, Asia, and other regions.
- Individual outcomes vary widely. Some Pi*ZZ individuals develop severe lung and liver disease; others remain relatively healthy into old age. The reasons for this variability are not fully understood.
- This is a rare disease. Not all pulmonologists or hepatologists have extensive experience with Alpha-1. Connecting with an Alpha-1 Foundation Clinical Resource Center or experienced specialist is often the single highest-value step a patient can take.
