Q

What are the criteria for lung transplantation?

A

Patients with end-stage lung disease that meet following criteria:
1. >50% risk of death from lung disease within 2yrs
2. >80% likelihood of surviving at least 90 days post-transplantation
2. >80% likelihood of 5yrs post-transplant survival from general medical perspective

Q

What are the indications for single vs double lung transplant?

A
  • Single lung transplantation is generally performed in patients with COPD or ILD
  • Double lung transplantations are generally reserved for suppurative lung diseases such as CF and bronchiectasis or pulmonary vascular diseases
  • Double lung transplants can be considered for COPD or ILD if benefits are thought to outweigh the risks such as in younger patients or if diseases complicated by pulmonary hypertension

Q

What are some absulute contraindications for lung transplantation?

A
  1. A history of malignancy in the past five years, or previous two years if the
    malignancy has low risk of recurrence; for example, a basal cell skin carcinoma.
  2. Untreatable significant heart, liver, kidney or brain dysfunction
    (unless combined organ transplantation can be performed).
  3. Uncorrected atherosclerotic disease with suspected or confirmed end organ
    ischaemia or dysfunction and/or coronary arterydisease not amenable to
    revascularisation.
  4. Acute illness such as sepsis, myocardial infarction, and hepatic failure would be
    contraindications.
  5. Chronic infection with highly virulent or resistant organisms that are poorly
    controlled pre-transplant.
  6. Mycobacterium abscessus particularly seen in patients with cystic fibrosis is
    deemed a contra indication.
  7. Significant chest wall or spinal deformity.
  8. Obese patients with a BMI >35 kg/m2
  9. Current non-adherence to therapies would be a worrying sign suggesting
    someone should not be transplanted.
  10. As mentioned by the candidate here, psychiatric or psychological conditions with
    inability to cooperate with treatments and healthcare team.
  11. No social support system.
  12. Severely impaired functional status with very poor rehabpotential.
  13. Substance abuse including smoking or dependence.

Q

Whar are some relative contraindications for lung transplantation?

A
  1. Age > 65 (usual limit for single lung, age 60 might be considered max age for double lung).
  2. BMI > 30 kg/m2
  3. Severe malnutrition (local center BMI < 17/kg/m2)
  4. Severe osteoporosis.
  5. Resistant organisms colonising the patient, such as burkholderia cenocepacia.

Q

What is Yellow Nail syndrome?

A

Yellow Nail Syndrome (YNS) is a rare disorder characterized by three main symptoms: yellow, thickened nails that grow slowly or detach; respiratory issues such as chronic cough, bronchiectasis, and pleural effusion; and swelling in the lower limbs due to lymphedema. The exact cause of YNS remains unknown, but it is often associated with autoimmune diseases, lymphatic disorders, or cancers.

The condition primarily affects adults over 50, though it has been reported in children as well. Some researchers suggest that YNS may be linked to improper circulation, lymphatic drainage issues, or fluid buildup around the lungs. Treatment focuses on managing symptoms rather than curing the syndrome. For nail changes, topical vitamin E and oral antifungal medications like itraconazole may help improve nail growth. Respiratory symptoms are treated with appropriate medical interventions, while swelling can be managed with compression therapy.

Despite its rarity, YNS can significantly impact quality of life. Early recognition and symptom management are crucial for improving patient outcomes. If you suspect YNS, consulting a healthcare provider for proper diagnosis and treatment is recommended.
