Evaluation of Dry Eye Severity and Ocular Surface Inflammation in Patients with Pemphigus and Pemphigoid.

PURPOSE: To evaluate ocular surface involvement, tear cytokine levels, and histopathological changes in pemphigus and pemphigoid patients. METHODS: A total of 22 patients (15 pemphigus and 7 pemphigoids) and 21 non-diseased controls were enrolled in our study. All participants underwent ocular surface evaluation, which included ocular surface disease index test, slit lamp observation, dry eye-related examination, tear multicytokine analysis, and conjunctival impression cytology. RESULTS: Pemphigus and pemphigoid patients presented much more severe conjunctivochalasis, corneal epithelial defects, corneal opacity, symblepharon   and dry eye. Severe ocular surface squamous metaplasia and a significant increase of tear macrophage inflammatory protein-1beta, tumor necrosis factor-alpha, interleukin (IL)-1ß, IL -6, and IL-8 occurred in pemphigus and pemphigoid patients. CONCLUSIONS: Our results revealed that ocular surface inflammation and dry eye persist in most pemphigus and pemphigoid patients, and do not occur in parallel with the systemic course. Regular ophthalmological examinations and local anti-inflammatory should be provided for pemphigus and pemphigoid patients.

Management of auto-immune blistering disease in an older patient with severe intellectual disability.

Management of chronic oral mucosal diseases might be challenging in older individuals with intellectual disability because of associated comorbidities, variable clinical presentations, and various barriers imposed by the intellectual disability. This report describes the presentation and management of pemphigus vulgaris in an older female with severe intellectual disability.

Wound myiasis by housefly in a patient with pemphigus vulgaris in Riyadh, Saudi Arabia.

Myiasis is the infestation of live vertebrates by dipterous larvae. Cutaneous myiasis is the most common form, although many organs can be infected by these larvae. Cutaneous myiasis is divided into 3 forms: localized furuncular, migratory, and wound myiasis, which have a worldwide distribution, but tropical and subtropical countries have a heavier burden of the disease. Herein, we report a case of scalp wound myiasis in a patient with pemphigus vulgaris caused by Muscidae domestica (M. domestica) in Riyadh, Saudi Arabia. Cases of M. domestica myiasis are limited in the literature. We would like to raise awareness regarding the possibility of cutaneous myiasis in M. domestica in Riyadh, Saudi Arabia.

A case report of esophageal cancer in a patient with pemphigus vulgaris: A coincidence or something beyond that?

BACKGROUND: Pemphigus is a group of rare but serious autoimmune blistering disorders, affecting skin and mucus membrane. Different reports have been published in respect to the coexistence of pemphigus with neoplasms, especially lympho-proliferative ones. CASE: Here, we have reported a patient previously diagnosed with pemphigus vulgaris (PV) who developed esophageal squamous cell carcinoma (SCC). CONCLUSION: Dyspepsia and dysphagia in patients with PV might not be merely due to pemphigus erosions or simply an adverse effect of systemic corticosteroid such as irritant or candidal esophagitis and should raise the suspicion of more serious conditions in case of resistant symptoms without appropriate response to treatment.

Emotions at diagnosis in patients with bullous diseases.

BACKGROUND: Diagnosis of a severe condition may have a strong emotional impact on patients. Specific emotions experienced when receiving the diagnosis of a bullous disease have not been investigated. METHODS: Adult patients diagnosed with a bullous condition were recruited through the Italian Association of patients with pemphigus and pemphigoid (ANPPI). Information was collected online on sociodemographic and clinical data. We asked which emotions the patient experienced at the time of the diagnosis, i.e., isolation, anger, confusion, sadness, despair, disregard, fear, avoidance, and challenge. Also, the patients reported to whom they talked as soon as they had the diagnosis. RESULTS: Data were collected on 105 patients, most of whom were affected by pemphigus vulgaris. The emotion most frequently experienced at diagnosis was confusion (47.6% of patients). More than 30% of patients reported sadness and fear, 12.5% anger, and 10.5% despair. A significantly higher percentage of women than men experienced isolation and despair. Despair was more frequent in patients who were older at diagnosis. Patients with children experienced more sadness and despair, and less avoidance and challenge, while those who had a relative with a bullous disease reported less fear, and more challenge. CONCLUSIONS: Clinicians should be aware of the emotions of the patient when communicating the diagnosis of severe conditions, such as bullous diseases. Active listening and empathy are necessary to provide patients with correct information on the disease, so that they are not overwhelmed with negative emotions.

Rescue treatment with intravenous immunoglobulin and amniotic membrane dressing in refractory paediatric pemphigus vulgaris with sepsis.

We report a case of refractory paediatric pemphigus vulgaris with sepsis, treated successfully with intravenous immunoglobulin (IVIG) and amniotic membrane dressing. The patient was initially started on oral prednisolone (1 mg/kg/day) and dapsone 50 mg once daily. Azathioprine 50 mg orally was then used in place of dapsone due to rapid disease progression with extensive skin involvement. However, the patient developed sepsis and azathioprine had to be discontinued. Because of rapidly progressive disease and sepsis, the patient was put on IVIG at a dose of 2 g/kg in divided doses over 3 days along with amniotic membrane dressing. There was marked improvement after 2 weeks of follow-up.

Pruritus Is Associated with an Increased Risk for the Diagnosis of Autoimmune Skin Blistering Diseases: A Propensity-Matched Global Study.

Autoimmune bullous skin diseases (AIBDs), such as bullous pemphigoid (BP) and pemphigus, are characterized and caused by autoantibodies targeting structural proteins. In BP, clinical experience and recent systematic evaluation identified pruritus to be common and an important cause of impaired quality of life. Furthermore, chronic pruritus may be the sole clinical symptom of BP. In pemphigus, a retrospective study recently documented a high prevalence of pruritus. The temporal relation between pruritus and BP/pemphigus are, however, unknown. Likewise, the presence of pruritus in AIBDs other than BP and pemphigus is unknown. To address this, we performed propensity-matched retrospective cohort studies using TriNetX, providing real-world patient data to (i) assess the risk to develop AIBDs following the diagnosis of pruritus and (ii) vice versa. We assessed this in eight AIBDs: BP, mucous membrane pemphigoid (MMP), epidermolysis bullosa acquisita, dermatitis herpetiformis, lichen planus pemphigoides (LPP), pemphigus vulgaris, pemphigus foliaceous, and paraneoplastic pemphigus (PNP). For all AIBDs, pruritus was associated with an increased risk for the subsequent diagnosis of each of the eight investigated AIBDs in 1,717,744 cases (pruritus) compared with 1,717,744 controls. The observed hazard ratios ranged from 4.2 (CI 3.2-5.5; p < 0.0001) in MMP to 28.7 (CI 3.9-211.3; p < 0.0001) in LPP. Results were confirmed in two subgroup analyses. When restricting the observation time to 6 months after pruritus onset, most HRs noticeably increased, e.g., from 6.9 (CI 6.2-7.9; p < 0.0001) to 23.3 (CI 17.0-31.8; p < 0.0001) in BP. Moreover, pruritus frequently developed following the diagnosis of any of the eight AIBDs, except for PNP. Thus, all AIBDs should be considered as differential diagnosis in patients with chronic pruritus.
