Eyes

  • Dry Eyes

    This result emphasizes the role of evaporative dry-eye condition in patients with ocular MMP. Tear osmolarity may be considered as a useful test in the diagnostic assessment of dry eye associated with MMP and for targeting therapeutic decisions. [ncbi.nlm.nih.gov]

    Because dry eye syndrome is often associated with MMP, dry eye therapy might be beneficial. [hopkinsmedicine.org]

    Eyes This may start with conjunctivitis and grittiness of the eye. Dry eyes may result from lacrimal gland involvement. [patient.info]

    The scarring of the conjunctiva can also results in dry eye and disruption of the corneal epithelium Eyelids may also turn in at the lid margin resulting from the scarring process of the conjunctiva. [pemfriends.co.uk]

    It may be confused with other eye conditions, including ocular rosacea and dry eye syndrome, so it is important for these patients to have ongoing follow up with an ophthalmologist experienced in anterior ocular surface disease, ideally. [dermcoll.edu.au]

  • Lacrimation

    Postoperative Cases and Surgical Procedures Systemic Disease (see under separate chapter Systemic Diseases) Trauma (Injury), Chemical Burns, Toxic Deposits Tumor, Neoplasma Cornea Glaucomas, Ocular Hypertension Hypertensive Retinopathy Iris and Ciliary Body Lacrimal [atlasophthalmology.net]

    Dry eyes may result from lacrimal gland involvement. [patient.info]

    The conjunctival scarring also leads to obliteration of the lacrimal ductules and accessory glands of Wolfring and Krause, as well as loss of goblet cells, causing dry eye symptoms secondary to aqueous tear deficiency and evaporative tear dysfunction. [healio.com]

    Recurrent inflammation causes loss of Goblet cells and obstruction of lacrimal gland ductules, leading to aqueous and mucous tear deficiency. [3] [15] The resulting xerosis is severe, and along with progressive subepithelial fibrosis and destruction of [eyewiki.aao.org]

Skin

  • Blister

    Mucous membrane pemphigoid is a rare autoimmune blistering disease primarily affecting mucosal surfaces. Blistering and scarring may occur in the eyes, mouth, esophagus, larynx, and on the vulva. [ncbi.nlm.nih.gov]

    Intense, often generalised, pruritus accompanies skin involvement (tense blisters or erosions on normal or erythematous skin). Head and neck involvement is common. [patient.info]

    Blisters in the oral cavity occur in up to 30% of patients, and they usually occur when the cutaneous disease is extensive. [clevelandclinicmeded.com]

Face, Head & Neck

  • Epistaxis

    Ocular involvement can lead to blindness because of inflammation and scarring involving the: Lens Cornea [ 7 ] Iris Lobe Some patients with CP have only eye involvement. [ 1 ] Nose This may manifest first with epistaxis. [patient.info]

Neurologic

  • Burning Sensation

    The disease had started as tense blisters associated with a burning sensation over the lower part of her back, gradually followed by involvement of her chest, upper part of her back, and arms. [ncbi.nlm.nih.gov]

    Case Report A 45 year old female patient reported to the department of Oral medicine and Radiology with a complaint of burning sensation and tenderness in the gums on intake of spicy food for the past 9 months. [jofs.in]

    He complained of burning sensation and soreness of the gums since 3 months and aggravation of pain on having spicy foods. Systemically, the patient was healthy without any adverse habits like smoking. [ijohsjournal.org]

    Pain of variable intensity or burning sensation may be the chief complaint (5, 6). DG may be a clinical manifestation of several underlying diseases (2, 4, 5, 9, 15, 16). [medicaljournals.se]

    Case Report A 60-year-old female presented with a 2-year-history of burning sensation in both eyes, progressing to limitation of eye movement and diminution of vision. [ijdvl.com]

Workup

RESULTS: Thirty-six of 52 patients (69%) who underwent only 1 biopsy at the first workup were positive. In 13 cases, the initial single biopsy was negative, and later biopsies were positive. [ncbi.nlm.nih.gov]

An ophthalmologic workup was negative for ocular mucosal disease involvement. Direct immunofluorescence findings showed IgG and C3 deposits at the basement membrane zone. [guwsmedical.info]

Treatment

Obvious progression was observed in 2 patients who had refused systemic treatment at an early stage. 10 eyes showed progression while on systemic treatment. [ncbi.nlm.nih.gov]

Patients usually show decreased conjunctival hyperemia within weeks of starting treatment. Immunosuppressive treatment is usually continued 2 to 3 years into remission. [healio.com]

Prognosis

The target antigens, autoreactive immune responses, microscopic features, treatment and prognosis vary from one disease to the other. [ncbi.nlm.nih.gov]

The condition usually begins in late adulthood (e.g. 50’s or 60’s), affects more women than men, and has a variable prognosis. Scarring of the affected mucosa of the eye may lead to blindness and tends to be the most feared complication. [autoimmune.org]

Treatment, Complications, and Prognosis Depending on the severity of the disease process, topical or systemic corticosteroids may be used. [guwsmedical.info]

Prognosis We agree with other authors that severe keratoconjunctivitis sicca and advanced ocular cicatricial disease and especially active inflammation have a poor prognosis. [healio.com]

Epidemiological studies showed some triggers to the development of autoimmune dysregulation, e.g. drugs. Furthermore, it has been shown that genetic factors play a role in the pathogenesis of the disease. [clinicaltrials.gov]

Pathophysiology

There is variety in the way CP presents clinically and some variety in the pathophysiological detail between patients. [ 2, 3 ] It can be difficult to distinguish from other autoimmune blistering diseases which may have mucosal involvement (for example [patient.info]

[…] and response to therapy Background Epidemiology Incidence – 6-14/million (Baum, 2014) Age – onset ≥60 years; rare in children ≥70 years – incidence significantly increases ≥90 years – relative risk is 300-fold higher than ≤60 years Sex – M:F, equal Pathophysiology [arupconsult.com]

Pathophysiology The exact cause of MMP is unknown. It is an autoimmune disorder (i.e. it occurs when the body produces autoantibodies against healthy ‘self’ tissue). [news-medical.net]

Prevention

Early diagnosis and treatment could prevent severe consequences of the disease in their full-blown forms. [ncbi.nlm.nih.gov]

The cornea (the clear layer in front of the iris and pupil) can become cloudy, preventing light from reaching the retina and decreasing vision. [merckmanuals.com]
