e. Grade 5
E
Group 1: pulmonary arterial hypertension
Group 2: pulmonary hypertension due to left heart failure
Group 3: pulmonary hypertension due to lung diseases and/or hypoxia
Group 4: chronic thromboembolic pulmonary hypertension and other obstructions
Group 5: pulmonary hypertension with unclear and/or multifactorial mechanisms

Group 3: Obstructive sleep apnea
Group 4: Recurrent thromboemboli
Which is the first mutation discovered in familial pulmonary arterial HPN
a. serine kinase BRAF
b. threonine kinase BRAF
c. ATP-binding cassette protein number 3 (ABCA 3)
d. bone morphogenetic protein receptor type 2 (BMPR2)
D
Uncommon autoimmune disease wherein kidney and lung injury are caused by circulating autoantibodies against the non collagenous domain of the α3 chain of collagen IV
a. idiopathic pulmonary hemosiderosis
b. goodpasture syndrome
c. polyangiitis with granulomatosis
d. pneumonia
B
Which of the following is previously called “Wegener granumomatosis” that involves the URT and/or the lungs with important histologic features such as capillaritis and scattered, poorly formed granulomas
a. idiopathic pulmonary hemosiderosis
b. goodpasture syndrome
c. polyangiitis with granulomatosis
d. pneumonia
C
Which is the marker of inflammation that is elevated in bacterial and viral infection in community acquired pneumonia
a. procalcitonin
b. hemagglutinin
c. neuraminidase
d. calcitonin
A
hemagglutinin: attach the virus to its cellular target via sialic acid residues on surface polysaccharides
neuraminidase: facilitates the release of newly formed virions that are budding from infected cells by cleaving sialic acid residues
