1. The document discusses updates to the 2018 GOLD and GINA guidelines for chronic obstructive pulmonary disease (COPD) and asthma management.
2. New recommendations include the use of single-inhaler triple therapy and macrolide antibiotics to reduce exacerbations in COPD, as well as considering inhaled corticosteroids for mild asthma.
3. The benefits of new drug delivery methods, combinations therapies, and treatments targeting specific asthma and COPD phenotypes are summarized from recent clinical trials.

2. Obstructive Lung Diseases
Integrity and elasticity of lung : DESTROYED
Poor elastic recoil: Air trapping (Hyperinflation)
Problem is with expiration.
Patient has to force the air out using abdominal & intercostal muscles: EXERTION
In RLC: FEV1/FVC is normal. (both the variables are decreased)

• Launched in 1997 in collaboration with the NHLBI, NIH and WHO.
• Non-biased review of the current evidence for assessment, diagnosis
and treatment of patients with COPD that can aid the clinician.
Objectives
Recommend effective management and prevention strategies.
Increase awareness among medical community, health officials and the
general public
Decrease morbidity and mortality through implementation of effective

• New formulation:
• Drug crystals are suspended in HFA based propellant
by engineered low-density phospholipid particles.

ADVANTAGES
1. Porous particle + drug crystal mixtures remain afloat instead of
sedimenting
2. Prevents flocculation/aggregation of drug particles
3. Decreased DDI, decreased DCI
4. Size: 2-3 um: optimum
5. Low spray velocity HFA propellant: decreased dysphonia

ICS should be considered for
patients with mild asthma
(rather than SABA alone)
• Reduces R/O

32. Eosinophils in Asthma

By targeting the interleukin receptor rather
than the cytokine; luminal depletion of
eosinophils can occur which maybe related to
greater clinical efficacy.

Results
34. Other key updates: GINA 2018
1. New Section added: Perimenstrual (catamenial) asthma
• Asthma worse perimenstrually in ~20% women
• More common in women with high BMI; often have dysmenorrhea and shorter cycles.
• Add-on treatment: LTRA may be helpful
(Sanchez-Ramos; Exp Rev Respir Med 2017)
2. New therapy added: HDM-SLIT Therapy
• When medication is discontinued, symptoms may recur. This is where allergen immunotherapy (AIT) comes
into play
• Repeated doses of a specific relevant allergen for the treatment of IgE-mediated allergic disease
3. Evidence A: recommendation against stopping ICS during pregnancy
• Stopping ICS increases the risk of exacerbations in pregnancy
(Schatz, AAAI 2005; Murphy, Thorax 2006; Murphy, Clin Chest Med 2011)

35. To sum up,
1. Quality of life (QoL)
2. EBM
3. Road to future discoveries
35
Category A: Rich body of data: substantial number of studies involving a substantial number of participants
Category B: limited number of patients, post-hoc or subgroup analysis of RCTs, meta-analysis of RCTs
Moderate exacerbations were defined as those requiring treatment with systemic steroids.
Severe exacerbations were defined as those that led to hospital admission and/or death.
Step 1:
No night awakening symptoms
No exacerbation in the last 1 year
Qulaity of life (QoL)
is the end-point around which newer therapeutic targets are being designed.
Mimics Rx guidelines for other chronic diseases: HTN, diabetes & cancer.
GOLD & GINA reinforce our “faith” in EBM.
ICS: forms the basis of therapy in Asthma is C/I as a single agent in COPD due to fatal pneumonia.
Theophylline (non-selective PDE #) removed from Rx protocol – No effect on exacerbation rates and minor Bd effect at near toxic doses
Road to future discoveries:
Inventing newer formulations (e.g. HFA-propellant based co-suspension)
Aiming newer therapeutic targets (e.e.IL-5⍺ R)
