念珠菌病 candidiasis
一.Defination candidaalbican may cause different types of lesions of the skin, nails, mucous membranes ,and viscera, which is called candidiasis. normal inhabitant conditioned pathogen, ( autogenous infection ) (1)hypoimmunity (2)local surrounding changed. (3)Antibiotic, immunity inhibiter,etc.
二.Etiopathogenisis Candida albican is the commonest algogen and its virulence is the strongest. normal inhabitant(spore): 1. cell immunity ↓ primary infection: the phagocytosis of neutrophil decreased. Lack of myeloperoxidase and aggregation factors. Second infection: blood glucose↑,VitA ↓,AIDS.
Iatrogenic factors:using broad-spectrum antibiotic, adrenal cortex hormone, immunity inhibiter, radiotherapy and chems. Spore hypha Aherence of cell well ↑ The ability of resistence of phagocytosis↑ The production of toxin
三. Clinical apparence : (一) mucocutaneous candidiasis (二) systemic candidiasis (三) disseminated candidiasis
1. thrush • grayish white membrane plaques are found on the surface of the oral mucous membrane, gingival, tongue.
2. Candidal vulvovaginitis : • white color pseudomembrane • fluor albus↑(cheese, bean dregs secretion) • the cunnus is erythematous and pruritic. • Pregnancy and DM are prone to develop disease . • Pseudohypha and clumped germ.
3. Candida balanitis • (1)Glans and coronary sulcus are susceptible. • (2)Erythema, superficial erosion pseudomembrane • (3)Apparent pruritus • (4)over-long acrobystia and DM are susceptible. • (5) Pseudohypha and clumped germ.
4. Candida fingerweb erosion:related to fatness , occupation etc.
5.Candidal intertrigo 〈1〉Child or obesity. 〈2〉 The folds of the body. 〈3〉 Erubescence, erosion, effusion and incrustation. 〈4〉 Erythraeous papule, desquamation
6. Popular candidiasis • obesity • Chest-back, perineum • Flat dark red papule • With clear boundary and albicans ring scale. • Pruritus.
7. Candidal paronychia and onychitis: Involving finger nail. red swelling nail groove, epinephelus nail plate with white spotting.
8.Chronic mucocutaneous candidiasis • With cryptorrheic or immunocopromiseddisease. • Childhood • Heredity • verrucous hyperplasia with dirty and thick crust.
Systemic candidiasis 〈一〉Candia albicans can infect many organs ,including alimentary canal, respiratory apparatus, urinary system, endocardium and meninges. 〈二〉 susceptible population: DM, malignant tumor, leukemia,AIDS 〈三〉 susceptible factors: using the long-time , broad-spectrum antibioticm and corticosteroids; radiotherapy; chemo.
disseminated candidiasis 1 involving many systems at the same time 2 candidal septicemia 3 bad prognosis.
四. Diagnosis and differential diagnosis All kinds of clinical appearances and fungi tests(pseudohypha germ and hypha→pathopoiesis)
五 prevention and cure tropical treatment: mucocutaeous type 1. 2%clotrimazole cream , miconazole cream . compound resorcinol liniment+ power 2 . nystatin100,000u + camphor sulphur calaminalotion 100mlnystatin suspl.( nystatin100,000u+ glycerol20ml+ distilled water80ml) 3. nystatin suppository(5000-10,000 u)qnX1-2w
(二) oral medication : Systemic and disseminated candidiasis or primary candidiasis 1. ketoconazole 0.2qd, vaginitis5-10d. 2. nystatin 200,000-400,000 u qd X 1w(alimentary canal) 3. polyaldehyde nystatin 50,000 u +NS5ml → air duct inhalation 4. amphotericinB5mg + aqua pro injectione20ml →5ml inhalator Bid –qid.
5. AmphotericinB 0.5-1mg/kg/d intravenous drip • or 5-flucytosine 2-3g/d by mouth • 6. Fluconazol:50-100mg/d, • course of treatment according to pathogenetic condition • Itraconazole 0.2g/d • course of treatment according to pathogenetic condition • 8. Take-down cause of a disease and preservation
