Sinusitis Signs and Symptoms (9)
- Mucopurulent discharge
- Nasal congestion
- Facial pain – eye pain or retroorbital pain
- Decreased sense of smell
- Can have persistent fever
- Persistent colored nasal discharge for >4 days
- Mucosal inflammation on nasal endoscopy
- X-ray findings not reliable
- Same organisms as lung
Sinusitis Treatment (3)
- Sinus rinse
- Antibiotics
- Surgery in new guidelines
Polyposis (5 with tx)
- 6-40%
- Nasal air obstruction
- Loss of taste or appetite
- Persistent epistaxis
- Treatment – Topical steroids, macrolide antibiotics, antibiotics, surgery
CF: Gastrointestinal Disease (6)
- Pancreatic insufficiency/malabsorption
- Lipo-soluble vitamin deficiency (ADEK)
- Failure to thrive - hypoproteinemia and edema
- Neonatal intestinal obstruction (15%)
- Recurrent distal intestinal obstruction syndrome (DIOS)
- Biliary stasis - portal hypertension; 2-5% pts
Pancreatic Insufficiency: Clinical Manifestations (5)
- 85% rate of pancreatic insufficiency
- Frequent bulky, greasy stools, floating stools
- Failure to thrive
- Abdominal distention
- Crampy abdominal pain
Nutritional Complications (4)
- Edema and hypoproteinemia
- Acute salt depletion
- Anemia
- Zinc deficiency – acrodermatitis enteropathica
a. A baby that cannot absorb zinc in breastmilk
b. Unusually severe diaper and/or facial rash
c. May have edema → check/test for edema on sacral area
Cystic Fibrosis Liver Disease (5)
Diagnosed when there are at least 2 of the following 4:
- Hepatomegaly and/or splenomegaly
- Liver function tests abnormalities on 3 tests in a 12 month period
- Portal hypertension or abnormal liver echo texture on ultrasound
- Cirrhosis on liver tissue biopsy.
- Treatment of ursodeoxycholic acid (ursodiol) is the recommended treatment
Other GI Complications (2)
- Distal intestinal obstruction syndrome (DIOS): DIOS is managed using osmotic laxatives to promote lower bowel clearance. The use of sodium meglumin diatrizoate (Gastrografin) enemas can be used for a near complete obstruction by an experienced radiologist
- Rectal prolapse
Pancreatitis as only manifestation (4)
- 18 year-old with acute abdominal pain. Amylase-792; lipase-950. Diagnosed with acute pancreatitis. Mutation analysis – 1717-1G>A and 3849+10kbC>T
- Sweat chloride – 84 meq/l
- Chest x-ray normal
- Pulmonary function tests normal; Indicates longer life expectancy if no lung disease
Endocrine Manifesation: Cystic Fibrosis Diabetes mellitus (CFRD) (8)
- Result of the fatty infiltration and destruction off the islet cells due to the thick viscous secretions in the pancreas.
- Microvascular complication of diabetes due to hyperglycemia
- Renal disease
- Retinopathy
- Peripheral neuropathy are associated.
- Average age of onset – 18-21 years; 16%
- Insidious onset and mild clinical course
- Ketoacidosis is rare.
Oral glucose test with CFRD (2)
At age 10, an oral glucose tolerance test is done annually to screen for CFDR.
- Hemoglobin A1C is not recommended since is underestimates overall glycemic control.
* Drink set amount of glucose then do blood draws q30 min - Insulin is used to treat CFRD
Preventative Measures w/ CF (4)
- Routine immunizations
- Influenza vaccine
- Children with Down syndrome or cystic fibrosis also are not recommended to receive palivizumab, even though some evidence shows that these children may be at higher risk for RSV
- Pneumococcal vaccine? – variable recommendations on PCV23 (the addition of pneumococcal 23 because it is not a conjugated vaccine; cannot be given until 2 years old)
CF Management/Treatment (9)
- Table salt supplementation
- Fluoride supplementation
- Education of caregivers regarding harms of cigarette smoke exposure for children and provision of a smoke-free environment
- Airway clearance therapy
- Albuterol before percussion and postural drainage
- Infection control education
- Infection control measures to minimize transmission of bacterial infections to infants
- Influenza vaccination
- Palivizumab (for prophylaxis of respiratory syncytial virus)- Unlikely
Pulmonary Treatment (7)
- Aim of pulmonary disease treatment
- Optimize lung functioning
- Prevent disease progression
- Avoid complications.
Must
- Control of airway infections
- Clearance of airway secretions
- Decreasing inflammation in the lung.
CF Respiratory Management (6 w/ targeted genetic tx)
- Regular visits to CF Center
- Airway clearance
- Mucus thinners (DNase, hypertonic saline)
- Antibiotics (PO, IV)
- Anti inflammatory agents
- Targeted genetic treatment—
a. Ivacaftor
b. Combination of Ivacaftor/lumacaftor
Chronic Pulmonary Treatment (3)
- Airway Clearance
- Chest percussion and drainage is only treatment for infants and young children
- Postural drainage, active cycle of breathing, autogenic drainage, percussion, positive expiratory pressure, exercise high frequency chest wall oscillation; Twice a day to facilitate secretion removal
Airway clearance (6)
- Chest Physical therapy
- Vest – mechanical percussion
- Flutter, Acapella
- Breathing techniques: ACB
- Exercise
- None is superior
Chronic Pulmonary Treatment: Mucus Modifying Agents (4)
- Inhaled dornase alfa (recombinant human deoxyribonuclease); DNAse
- Digests the extracellular neutrophil derived DNA
- Assists with secretions in the lungs, along with hypertonic saline
- Very expensive
Chronic Pulmonary Treatment: Hypertonic saline 7%
Works by drawing water into secretions and is used to thin secretions to allow removal of
*Not good for bronchiolitis
Chronic Pulmonary Treatment: Anti-inflammatory drugs
High-dose ibuprofen
*While high dose ibuprofen decreases neutrophil migration in children from 6 years to 17 years, the therapy is not widely used due to risk of GI bleeding and frequent drug blood level measurements.
Chronic Pulmonary Treatment: inhaled antimicrobial agents (
- Eradicates initial P. aeruginosa growth
- Inhaled tobramycin for 28 days as part of eradication protocol
i. Tobramycin inhaled - > 6 years
ii. DRUG OF CHOICE - Aztreonam (2nd choice)
- Alternating inhaled antibiotics every months to decrease frequency - Colistin (3rd choice)
Chronic Pulmonary Treatment: Other (3)
- The use of Ivacaftor is limited to patients who carry at least one G551D mutation
- No corticosteroids
- Oral azithromycin dosed three times a week are used; Must be screened for atypical mycobacterial infection before starting long-term azithromycin
Acute Pulmonary Exacerbations: Main treatment (3)
- For 13 days
- Aminoglycosides are most common class of antipseudomonials
* Side effects → ototoxicity and nephrotoxicity - Beta-Lactam antibiotics—Not recommended in the CF guidelines
Acute Pulmonary Exacerbations: Pneumothroax (6)
- Increased intrapleural pressure due to inflammation and obstruction
- Acute onset of chest pain and dyspnea and is confirmed by chest X-ray
- Larger pneumothorax >2 cm Admit and chest tube
- Smaller pneumothoraxes (<2 cm)
* Managed by observation and discontinuation of positive pressure. - Surgical or chemical pleurodesis is used in recurrent large pneumothoraxes.
- Lung transplantation is a viable therapy for selected patients who have terminal lung disease
Acute Pulmonary Exacerbations: Hemoptysis (5)
- Results from the hypertrophy and proliferation of the bronchial arteries rupturing into the airways as a result of the disease process (Hurt and Simmonds, 2012).
- Scant (<5ml)
- Moderate (5-240 ml)
- Massive (>240 ml)
- Associated with advancing lung disease as well as vitamin K deficiency
Acute Pulmonary Exacerbations: Management (3)
- Antibiotic therapy
- Cessation of the anti-inflammatory drugs
- Limiting therapies for airway clearance
Management of GI Symptoms (6)
- Pancreatic enzyme replacement therapy (PERT)
a. Replacement with enzymes in the dosage ranges of 2000 to 2500 U/kg of lipase to a maximum of 10,000 U/kg/day.
b. Not over 24,000 units a day
* Risk of severe fibrosing colonopathy - Feeding (human milk, standard infant formulas, calorie- dense feedings, provision of educational resources for caregivers)
- Nutritional counseling
- Multivitamins
a. Vitamin A and K levels need to be monitored!! – unable to absorb these - Monitoring of fat-soluble vitamin levels
- Zinc supplementation
Ivacaftor (Kalydeco) and CF (5)
- People ages 2 and over with the following 5 mutations:
a. 3849+10kbC->T
b. 2789+5G->A
c. 3272-26A->G
d. 711+3A->G E831X. - Improve the function of a defective CFTR protein
- With this mutation the CFTR protein acts like a locked gate, preventing the proper flow of salt and fluids in and out of the cell.
- Kalydeco helps unlock that gate and restore the function of the CFTR protein, allowing a proper flow of salt and fluids on the surface of the lungs.
- Thins the thick, sticky mucus caused by CF that builds up in the lungs.
CF Primary care (9)
- Nutrition including use of Cycloheptadine
- Development
- Sleep
- Elimination
- Immunizations
- School
- Psychosocial
- Sexuality/Reproductive
- Routine Screening as recommended by AAP
Transplantation (7)
- Declining lung function FEV1 ≤ 30
- Pulmonary hypertension (>35 mmHg)
- Infections with poor recovery from pulmonary exacerbations
- Nutrition; Worsening status despite supplements and appetite stimulants
- Life threatening hemoptysis
- Pneumothorax
- Diabetes
Transitioning in CF (2)
- Should begin at around age 12
2. It is important to have a multidisciplinary team
