Systemic diseases of connective tissue - Rheumatic diseases (collagenoses) Lecture Systemic diseases of connective tissue - Rheumatic diseases (collagenoses) Lecture

Rheumatic diseases a group of chronic diseases with systemic progressive disorganization of connective tissue Rheumatic diseases a group of chronic diseases with systemic progressive disorganization of connective tissue and vessels, as well as immune derangements.

Rheumatic diseases u Disease nature: infection-allergic. u Risk factors: heredity, infection, hypothermia, medicaments (drugs). Rheumatic diseases u Disease nature: infection-allergic. u Risk factors: heredity, infection, hypothermia, medicaments (drugs).

Common signs of diseases u Presence of chronic infection foci; u Immunologic homeostasis derangements; Common signs of diseases u Presence of chronic infection foci; u Immunologic homeostasis derangements; u Generalized vasculitis; u Chronic undulating course; u Systemic progressive disorganization of connective tissue.

Nosologic forms u Rheumatism; u Rheumatoid arthritis; u Systemic lupus erythematosus; u Scleroderma; u Nosologic forms u Rheumatism; u Rheumatoid arthritis; u Systemic lupus erythematosus; u Scleroderma; u Nodular periarteritis; u Bechterew`s disease; u Dermatomyositis.

Stages of connective tissue disorganization u Mucoid swelling, u Fibrinoid changes: (fibrinoid swelling, fibrinoid Stages of connective tissue disorganization u Mucoid swelling, u Fibrinoid changes: (fibrinoid swelling, fibrinoid necrosis), u Inflammatory-cellular reactions, u Sclerosis.

Predominant localization of affections Rheumatism – heart and vessels; Rheumatoid arthritis – joints; Systemic Predominant localization of affections Rheumatism – heart and vessels; Rheumatoid arthritis – joints; Systemic lupus erythematosus – skin, kidneys; Scleroderma – skin; Nodular periarteritis – arteries wall; Bechterew`s disease – articularligamentous apparatus of the spine; Dermatomyositis – skeletal muscular system.

Rheumatism Rheumatic endocarditis – is a chronic disease of infection-allergic nature with the progressive Rheumatism Rheumatic endocarditis – is a chronic disease of infection-allergic nature with the progressive disorganization of connective tissue and vessels Etiology: β-hemolytic streptococcus of А group

Connective tissue disorganization stages in case of rheumatism: u Mucoid swelling, u Fibrinoid changes: Connective tissue disorganization stages in case of rheumatism: u Mucoid swelling, u Fibrinoid changes: (fibrinoid swelling, fibrinoid necrosis), u Cellular reactions (formation of granulomas: blooming, fading, sclerosing – Aschoff-Talalaev`s nodules), u Sclerosis.

Clinicoanatomical forms of rheumatism: u Cardiovascular: predominant affection of the heart and vessels. u Clinicoanatomical forms of rheumatism: u Cardiovascular: predominant affection of the heart and vessels. u Polyarthritic: affection of the heart, vessels and joints. u Cerebral: affection of the heart, vessels and brain. u Nodose: affection of the heart, vessels and skin.

Cardiovascular form u Vessels – vasculitis; u Endocardium – endocarditis; u Myocardium – myocarditis: Cardiovascular form u Vessels – vasculitis; u Endocardium – endocarditis; u Myocardium – myocarditis: u Pericardium – pericarditis; u Rheumatic heart disease: combined affection of endocardium and myocardium; u Pancarditis: inflammation of all cardiac membranes (coats).

Endocarditis According to localization: parietal, chordal, valvular; u According to morphology: diffuse (valvulitis), acute Endocarditis According to localization: parietal, chordal, valvular; u According to morphology: diffuse (valvulitis), acute verrucous, fibroplastic, recurrent-verrucous. u Outcome – heart disease formation. u

Heart diseases u According to the origin: congenital and acquired; u According to morphology: Heart diseases u According to the origin: congenital and acquired; u According to morphology: stenosis, insufficiency, combined heart disease; u Isolated, associated heart disease.

Myocarditis u Productive (granulomatous), u Interstitial, exudative, diffuse, u Interstitial, exudative, focal. Outcome - Myocarditis u Productive (granulomatous), u Interstitial, exudative, diffuse, u Interstitial, exudative, focal. Outcome - cardiosclerosis

Pericarditis According to morphology: u Serous, u Fibrinous, u Serofibrinous. u Outcome – commissures Pericarditis According to morphology: u Serous, u Fibrinous, u Serofibrinous. u Outcome – commissures and pericardial cavity obliteration.

Cardiovascular form u Complications: thromboembolism, vascular thrombosis, infarctions of kidneys, spleen, brain; cirrhosis, banal Cardiovascular form u Complications: thromboembolism, vascular thrombosis, infarctions of kidneys, spleen, brain; cirrhosis, banal pneumonia. u Death causes: cardiac decompensation and general blood circulation disturbance, specific and nonspecific pneumonia, cerebral hemorrhage, intercurrent

Polyarthritic form of rheumatism u Is found in 10 -15% of patients; u Large Polyarthritic form of rheumatism u Is found in 10 -15% of patients; u Large joints are chiefly affected; u Inflammation pattern: serous, without the lesion of articular cartilage; u Heart and vessels are affected to a lesser degree. u Important! Has to be differentiated with rheumatoid arthritis!

Nodose (nodular) form of rheumatism u More often is found in children; u Connective Nodose (nodular) form of rheumatism u More often is found in children; u Connective tissue disorganization along the tendons; u Development of nodose erythema; u Outcome - scarring; u There are similar changes in other organs, but without the clinical manifestations.

Nodose form of rheumatism Nodose form of rheumatism

Cerebral form of rheumatism u Is found in children (juvenile chorea); u Vasculitis, degenerative Cerebral form of rheumatism u Is found in children (juvenile chorea); u Vasculitis, degenerative changes of brain cells; u Other organs are changing less.

RHEUMATOID ARTHRITIS RHEUMATOID ARTHRITIS

Rheumatoid arthritis u More often is found in women and children; u Etiology – Rheumatoid arthritis u More often is found in women and children; u Etiology – β-hemolytic streptococcus of В group u Rheumatoid factor – Ig М, G, A, is found in the blood u Small joints of hands and feet (more rarely) are affected

Anatomical pathology of rheumatoid arthritis 1. 2. 3 stages are distinguished: In the joint Anatomical pathology of rheumatoid arthritis 1. 2. 3 stages are distinguished: In the joint cavity - nebulous fluid, the cartilage is extant, areas of mucoid and fibrinoid swelling, necrosis, villi (compact casts) - «rice bodies» - are formed Villi overgrowth and cartilage destruction, excrescence of granulation tissue – formation of pannus Formation of fibro-osseous ankylosis
