📌The prototype patient of Ekbom’s syndrome…..


📍A Middle aged woman


📍Claims that she is being infected by some type of parasite, which she occasionally sees & usually feels on/under her skin, head ,eyes etc


📍May describe as a larva OR worm OR flea OR fungus OR simply a small organism


📍The belief qualifies for the definition of delusion


📍Onset-insidious usually ,rarely abrupt


📍Some might have had a real infestation earlier to which they attribute the current symptoms


📍Intense pruritus & dermatitis artefacta


📍Repeated scratching causing excoriations & injuries


📍Overuse of disinfectants /insecticides


📍Excavasations in search of parasites


📍Self mutilation-Self inflicted burn marks and scabs


📍Pits , ulcers , bruises or scars may be seen


📍Hair pulling, alopecia, Onychotillomania, Doctor shopping are usually seen in the patients


📍Repeated bathing & washing of clothes


📍Fear of contaminating other households


📍All the symptoms won't fit into one single organic disease


📍Matchbox sign/Specimen sign(bring specimens/skin particles/hair samples in small boxes)/wrapped in a paper/in plastic bags-for  evidence


📍Photos/self recorded videos will be shown by patient as evidences


📍May have hallucinations coexistent(formications-substance abuse, Cocaine bugs)


📍Other than the delusion of parasites, she reasons normally& appear normal



📍Bacterial superinfection


📌Approach to such patients…..


📍It is extremely challenging to diagnose & manage Ekbom syndrome


📍Exclude real infestation(Travel history, contact with infested patients, examination)


📍Find if its primary or secondary delusional parasitosis

(CBC,AEC,TFT,VDRL,LFT,RFT,HIV,VM, Vitamin levels, tox screen, neuroimaging)


📍If secondary,address the underlying cause


📍If primary, treat with empathy by associating with psychiatrist


📍Trying to covince them that they are wrong, will not work


📍Antihistamines ,topical medications for the injuries


📍Specific pharmacotherapy:-Antipsychotics(60-100% remission)


*1st line :- 


-Earlier drug of choice🡪Pimozide 1 mg to 10mg(Side effects-Extra pyramidal side effects,Cardiotoxic)


-Now a days, second generation anti psychotics are the first line of management


Risperidone(0.5-6mg)


Quetiapine(25-600mg)


Aripiprazole(2-30mg)


Olanzapine 5mg


*Long acting injectable anti psychotics if poor compliance
