Systemic sclerosis: The need for structured care

Web-based information on the treatment of the mouth in systemic sclerosis

BACKGROUND

To categorise the content and assess the quality and readability of the web-based information regarding treatment of the mouth in systemic sclerosis.

METHODS

An online search using three different search terms regarding the treatment of the mouth in SSc was undertaken using the Google search engine. The first 100 websites from each search were selected for analysis. Data recorded included DISCERN instrument scores along with the Journal of the American Medical Association (JAMA) benchmarks and the presence of the Health on the Net seal (HON). Flesch Reading Ease Scores, Flesch-Kincaid Grade Level, the Simplified Measure of Gobbledygook Index and Coleman-Liau index were calculated to assess readability.

RESULTS

Fifty seven of the first websites remained for analysis after applying appropriate exclusion criteria. The mean overall DISCERN score was 2.37 (±1.01). Only 4 websites (7%) achieved all four JAMA benchmarks. Only 12 websites (21.1%) displayed the HON seal. The reading level was found to be difficult to very difficult among the majority of websites.

CONCLUSION

The overall quality of the available online information concerning the treatment of the mouth of systemic sclerosis is questionable and requires a high level of reading skill. Further efforts should be directed toward establishing higher quality, reliable online information sources on the treatment of oral disease relevant to patients with systemic sclerosis.

Evaluation of Ocular Surface and Meibomian Glands in Patients With Scleroderma

PURPOSE

To evaluate the prevalence of dry eye and meibomian gland dysfunction in patients with scleroderma.

METHODS

A total of 32 patients with scleroderma (study group) and 31 healthy subjects (control group) were enrolled. Besides routine ophthalmologic evaluation, Schirmer 1 test, tear break-up time, tear osmolarity, ocular surface staining with fluorescein (Oxford score), and Ocular Surface Disease Index (OSDI) score, meibomian gland dysfunction evaluation (foamy tears, telangiectasia of the eyelid, eyelid contour abnormalities, and meibomian plugs), and meibography were performed.

RESULTS

Sixty-four eyes of 32 patients with scleroderma and 62 eyes of 31 healthy individuals were evaluated. Mean ages of the study group was 48.34 ± 9.73 years (21-62 years) and of the control group was 45.84 ± 4.42 years (38-54 years) (P = 0.067). Mean duration of systemic sclerosis or scleroderma in study group was 9.78 ± 7.40 years (1-30 years). Mean tear break-up time was shorter in study group than that in the control group (P < 0.0005). No statistical differences were detected for osmolarity, OSDI score, and Schirmer 1 values between groups (P = 0.051, P = 0.053, and P = 0.358, respectively). The prevalence of grade 1 and higher Oxford score was higher in the study group (P < 0.0005). Upper meiboscores of grade 1 and higher were found to be more common in the study group than those in the control group (P = 0.036). The presence of foamy tears and telangiectasia of the eyelids were significantly higher in the study group (P = 0.002 and P = 0.002, respectively). OSDI score was the only significantly correlated data with disease duration (Spearman ρ coefficient = 0.396, P = 0.001).

CONCLUSIONS

Evaporative type dry eye is more common in patients with scleroderma than the healthy population.

Validity and reliability of the Mouth Handicap of Systemic Sclerosis questionnaire in a UK population

BACKGROUND

The objective of this study was to explore the psychometric properties of the Mouth Handicap in Systemic Sclerosis (MHISS) specifically exploring aspects of validity and reliability of MHISS in UK SSc patients.

METHODS

A total of 150 questionnaires were distributed in this study at the Oral Medicine Department of UCLHT Eastman Dental Hospital, the Outpatient Rheumatology Clinic of the Royal Free Hospital and Scleroderma Family Day. Participants were asked to complete three questionnaires (SF-36, OHIP-14 and MHISS) along with a pro forma of demographic and disease-specific questions. Both convergent validity and internal consistency reliability were examined. The convergent validity was assessed by Spearman's correlation coefficient, and internal consistency reliability was assessed by Cronbach's alpha.

RESULTS

Of the 150 questionnaires distributed to participants, 68 respondents were included. With regard to construct validity, a low to moderate degree of convergent validity was found between MHISS total score and all SF-36 subscales. However, the total MHISS score was highly correlated to all OHIP subscales.

CONCLUSION

MHISS questionnaire is a self-administered patient-reported outcome measure that assesses the mouth disability in SSc patients. However, improving the global and oral health of SSc patients is important as there is no cure for the disease; thus, instruments that record the impact of the condition and indicate the effect of treatment on the lives of patients are of paramount importance. Current results demonstrate good preliminary psychometric properties (validity and reliability) in a UK population with further exploration of psychometric properties with an emphasis on interpretability required.

A Wide Spectrum of Ocular Manifestations Signify Patients with Systemic Sclerosis

Objectives: Systemic sclerosis (SSc) is a rare, chronic connective tissue disease involving multiple organ systems, including the eye. We evaluated the detailed clinical ocular manifestations of outpatients with SSc.Methods: Demographics, disease duration and subtype, nailfold capillaroscopy (NFC) patterns and laboratory parameters encompassing the autoantibody profile of 51 SSc patients were evaluated, and a general ocular examination was performed for each participant.Results: Twenty-nine patients (56.86%) had eyelid skin alterations, 26 (50.98%) had retinal abnormalities, 26 (50.98%) had cataracts, 8 (15.69%) had conjunctival changes, 7 (13.73%) had iris abnormalities, 33 (64.71%) suffered from dry eye disease (DED), and 11 (21.57%) suffered from glaucoma. Significant positive correlations were found between NFC data and both tear breakup time and Ocular Surface Disease Index test values.Conclusions: Eyelid skin abnormalities, DED and retinal abnormalities are among the most common SSc-related ocular involvements. Diverse ophthalmic findings are attributed to the heterogeneity of SSc.

Gastrointestinal and Hepatic Disease in Systemic Sclerosis

Although classification criteria for systemic sclerosis (SSc) do not incorporate gastrointestinal tract (GIT) manifestations often present in this disease, the GIT is the most common internal organ involved. Pathophysiology of GIT involvement is thought to be similar to other organs in SSc with fibroproliferative vascular lesions of small arteries and arterioles, increased production of profibrotic growth factors, and alterations of innate, humoral, and cellular immunity. These processes result in neuropathy progressing to myopathy with eventual fibrosis. Proper diagnostics and therapeutics for SSc-GIT involvement require the treating physician to have an understanding of an integrated approach and potential medication adverse effects.

Scleroderma skin ulcers definition, classification and treatment strategies our experience and review of the literature

BACKGROUND

Skin ulcers (SU) are one of the most frequent manifestations of systemic sclerosis (SSc). SSc-SU are very painful, often persistent and recurrent; they may lead to marked impairment of patient's activities and quality of life. Despite their severe impact on the whole SSc patient's management, the proposed definition, classification criteria, and therapeutic strategies of SSc-SU are still controversial.

OBJECTIVE

The present study aimed to elaborate a comprehensive proposal of definition, classification, and therapeutic strategy of SSc-SU on the basis of our long-term single center experience along with a careful revision of the world literature on the same topic.

METHODS

A series of 282 SSc patients (254 females and 28 males; 84% with limited and 16% diffuse cutaneous SSc; mean age of 51.5±13.9SD at SSc onset; mean follow-up 5.8±4.6SDyears) enrolled during the last decade at our Rheumatology Unit were retrospectively evaluated with specific attention to SSc-SU. The SSc-SU were classified in 5 subtypes according to prominent pathogenetic mechanism(s) and localization, namely 1. digital ulcers (DU) of the hands or feet, 2. SU on bony prominence, 3. SU on calcinosis, 4. SU of lower limbs, and 5. DU presenting with gangrene. This latter is a very harmful evolution of both DU of the hands and feet needing a differential diagnosis with critical limb ischemia.

RESULTS

During the follow up period, one or more episodes of SSc-SU were recorded in over half patients (156/282, 55%); skin lesions were often recurrent and difficult-to-heal because of local complications, mainly infections (67.3%), in some cases associated to osteomyelitis (19.2%), gangrene (16%), and/or amputation (11.5%). SSc-SU were significantly associated with lower patients' mean age at the disease onset (p=0.024), male gender (p=0.03), diffuse cutaneous subset (p=0.015), calcinosis (p=0.002), telangiectasia (p=0.008), melanodermia (p<0.001), abnormal PAPs (p=0.036), and/or altered inflammation reactant (CRP, p=0.001). Therapeutic strategy of SSc-SU included both systemic and local pharmacological treatments with particular attention to complicating infections and chronic/procedural pain, as well as a number of non-pharmacological measures. Integrated local treatments were often decisive for the SSc-SU healing; they were mainly based on the wound bed preparation principles that are summarized in the acronym TIME (necrotic Tissue, Infection/Inflammation, Moisture balance, and Epithelization). The updated review of the literature focusing on this challenging issue was analyzed in comparison with our experience.

CONCLUSIONS

The recent advancement of knowledge and management strategies of SSc-SU achieved during the last years lead to the clear-cut improvement of patients' quality of life and reduced long-term disability.
