Corticosteroid-induced hyperglycemia is increased 10-fold in patients with pemphigus

Metabolic adverse events associated with systemic corticosteroid therapy-a systematic review and meta-analysis

OBJECTIVES

To assess the risk of new-onset or worsening hyperglycaemia, hypertension, weight gain and hyperlipidaemia with systemic corticosteroid therapy (CST) as reported in published randomised control trial (RCT) studies.

DATA SOURCES

Literature search using MEDLINE, EMBASE, Cochrane library, Web of Science and Scopus STUDY ELIGIBILITY CRITERIA: Published articles on results of RCT with a systemic CST arm with numerical data presented on adverse effect (AE).

PARTICIPANTS AND INTERVENTIONS

Reports of hyperglycaemia, hypertension, weight gain and hyperlipidaemia associated with systemic CST in patients or healthy volunteer's ≥17 years of age.

STUDY APPRAISAL METHODS

Risk of bias tool, assessment at the level of AE and key study characteristics.

RESULTS

A total of 5446 articles were screened to include 118 studies with 152 systemic CST arms (total participants=17 113 among which 8569 participants treated with CST). Pooled prevalence of hyperglycaemia in the CST arms within the studies was 10% (95% CI 7% to 14%), with the highest prevalence in respiratory illnesses at 22% (95% CI 9% to 35%). Pooled prevalence of severe hyperglycaemia, hypertension, weight gain and hyperlipidaemia within the corticosteroid arms was 5% (95% CI 2% to 9%), 6% (95% CI 4% to 8%), 13% (95% CI 8% to 18%), 8% (95% CI 4% to 17%), respectively. CST was significantly associated hyperglycaemia, hypertension and weight gain as noted in double-blinded placebo-controlled parallel-arms studies: OR of 2.13 (95% CI 1.66 to 2.72), 1.68 (95% CI 0.96 to 2.95) and 5.20 (95% CI 2.10 to 12.90), respectively. Intravenous therapy posed higher risk than oral therapy: OR of 2.39 (95% CI 1.16 to 4.91).

LIMITATIONS

There was significant heterogeneity in the AE definitions and quality of AE reporting in the primary studies and patient populations in the studies. The impact of cumulative dose effect on incidental AE could not be calculated.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

Systemic CST use is associated with increased risk of metabolic AEs, which differs for each disease group and route of administration.

High prevalence of steroid-induced glucose intolerance with normal fasting glycaemia during low-dose glucocorticoid therapy: an oral glucose tolerance test screening study

OBJECTIVES

To evaluate the prevalence and risk factors of new-onset glucose metabolism impairment using an oral glucose tolerance test (OGTT) in patients with normal fasting glycaemia on long-term glucocorticoid (GC) treatment.

METHODS

An OGTT was performed in 150 patients without a previous history of pre-diabetes or diabetes who were diagnosed with inflammatory rheumatic diseases and treated with GCs >3 months. All participants underwent clinical and biochemical evaluation for risk factors of diabetes: age, sex, current and cumulative dose of steroids, treatment duration, waist circumference, BMI, Homeostatic Model Assessment for Insulin Resistance, fasting insulin concentration, family history of diabetes, CRP, 28-joint DAS with CRP, type of connective tissue disease and trunk fat percentage measured by DXA. Logistic regression analysis was conducted to evaluate the association between the presence of impaired glucose tolerance (IGT) in the OGTT and analysed risk factors.

RESULTS

A total of 102 patients (68%) had fully normal glucose tolerance. Diabetes, isolated impaired fasting glucose, isolated IGT and combined impaired fasting glucose + IGT was diagnosed in 3.3, 4.67, 19.33 and 4.67% of patients, respectively; 20% of participants had IGT or diabetes despite normal fasting glucose concentration. The median cumulative dose and current dose (5 mg) of GCs and treatment duration were similar compared with the normal glucose tolerance group. In a multivariate logistic regression model, only older age (particularly ≥50 years of age) and trunk fat percentage remained significant factors predicting IGT or diabetes in the OGTT.

CONCLUSION

New-onset GC-induced glucose intolerance, even in patients on long-term low-dose treatment, is prevalent despite normal fasting glucose concentration and patients should be screened with an OGTT despite the absence of classic risk factors of diabetes.

Efficacy and adverse reactions of methotrexate in the treatment of ocular cicatricial pemphigoid: A case series study

The application of methotrexate (MTX) in the treatment of autoimmune diseases has been gradually increasing, but reports of MTX treatment for advanced ocular cicatricial pemphigoid (OCP) are extremely rare. This study investigated the efficacy and adverse reactions of low-dose MTX in patients with OCP.This was a retrospective, noncontrolled, case series study. Eleven patients diagnosed with advanced OCP (4 cases in stage III and 7 cases in stage IV) were enrolled. Treatment by oral administration of MTX (7.5 ± 2.5 mg) alone was performed. Visual acuity of the patients, conjunctival inflammation, cicatrization, ocular surface keratinization, and toxic side effects of drugs were evaluated.All patients enrolled in this study were females aged 32 to 83 years. Patients were followed up for 4 to 33 months. Low-dose MTX improved visual acuity of 3 cases (6 eyes, 27.3%). Conjunctival inflammation of 5 patients (10 eyes) rested after treatment, and conjunctival inflammation of 3 cases (6 eyes, 27.3%) was decreased with an effective rate of 72.7%. Cicatrices of 8 cases (15 eyes) showed degeneration after treatment with an effective rate of 71.4% (15/21). Ocular surface keratinization receded in 4 cases with an effective rate of 66.7%. None of the patients discontinued the treatment due to severe toxic side effects. All patients tolerated mild drug-induced gastrointestinal reactions. Three patients terminated the treatment in advance after 4 to 6 months due to no improvement in the disease condition.Observation of clinical efficacy and safety findings demonstrated that low-dose MTX can be used to treat patients with advanced OCP.

Immunological markers as predictors of developing steroid-induced diabetes mellitus in pemphigus vulgaris patients: An observational study

The aim of this study was to evaluate the clinical importance of autoantibodies in pemphigus vulgaris patients who developed steroid-induced diabetes mellitus (SID) because of the glucocorticoid therapy of pemphigus.A total of 137 patients with pemphigus vulgaris were studied. Patients with SID and pemphigus were compared with those that had only pemphigus. The variables recorded were: age at diagnosis, sex, body mass index, presence of diabetes mellitus (DM), cumulative cortisone dose, treatment duration, value of anti-desmoglein 1 and 3, and anti-glutamic acid decarboxylase autoantibodies.A total of 31 patients (22.62%) that developed steroid-induced DM were identified. Anti-glutamic acid decarboxylase autoantibodies were positive in 20.75% of patients with pemphigus vulgaris and in 25.75% of patients with pemphigus vulgaris and SID.The overall anti-glutamic acid decarboxylase autoantibodies prevalence in pemphigus patients was high, and the risk of developing DM in patients with pemphigus remains a serious problem, being associated with increased risk of mortality.

Successful treatment of oral pemphigus vulgaris in an insulin-dependant geriatric patient

OBJECTIVE

To present a clinical report of a patient treated with corticosteroids for oral pemphigus vulgaris (PV) lesions.

BACKGROUND

PV is the type of pemphigus that most often affects the oral mucosa and tends not to appear in elderly people.

METHODS

Two biopsies were needed for diagnosis. She was treated with oral prednisone and topically with 0.05% clobetasol propionate.

CONCLUSION

An early diagnosis and treatment is needed for a good prognosis, especially in elderly patients with multiple systemic pathology.

Pemphigus and associated comorbidities: a cross-sectional study

BACKGROUND

Pemphigus is a rare autoimmune blistering disease, reported to be associated with other coexisting and autoimmune diseases, including thyroid diseases, rheumatoid arthritis, alopecia areata, vitiligo, systemic lupus erythematosus, scleroderma and rare entities such as myasthenia gravis.

AIM

To identify and describe patients with pemphigus with a diagnosed comorbidity, and to quantify the risk of additional comorbidities.

METHODS

This was a cross-sectional study of patients with pemphigus treated at a tertiary referral centre. Prevalence rates of 15 comorbid diseases were calculated. Age-standardized prevalence ratio (SPR) and 95% CI were calculated in comparison with prevalence rates in the general Canadian population using data from the Canadian Community Health Survey. Data were analysed using SAS software.

RESULTS

In total, 295 patients were identified. An increased risk of hypothyroidism (n = 38, SPR = 1.53, 95% CI 1.08-2.10) and inflammatory bowel disease (IBD) (SPR = 1.48, 95% CI 0.40-3.80), and a two-fold increased risk of diabetes (SPR = 2.20, 95% CI 1.64-2.87) were observed.

CONCLUSIONS

Patients with pemphigus have a higher incidence of hypothyroidism, IBD and diabetes compared with the general population. As part of pemphigus investigations and surveillance, investigating for these conditions may be considered.

Hyperglycemia induced by glucocorticoids in nondiabetic patients: a meta-analysis

BACKGROUND/AIMS

Glucocorticoids are associated with a number of side effects including the development of new-onset hyperglycemia or diabetes. The diagnosis and treatment of glucocorticoid-induced hyperglycemia are surprisingly undervalued by many health-care professionals, probably due to the lack of quality studies that assess specific reasons for and prevention of hyperglycemia. The aim of this meta-analysis was to evaluate the long-term incidence of glucocorticoid-induced hyperglycemia and diabetes in nondiabetic patients who received glucocorticoid treatment.

METHODS

We searched Medline, Embase, and the Cochrane Library (Central) until January 2014 for studies in which subjects received systematic glucocorticoid treatment and which evaluated whether subjects developed hyperglycemia or were diagnosed with diabetes following treatment. The primary outcome for this analysis was the incidence of hyperglycemia and the secondary outcome was the frequency of diabetes.

RESULTS

We identified 13 studies that met our inclusion criteria; 12 of the studies were retrospective or observational in design. We found that the rate at which patients developed glucocorticoid-induced hyperglycemia or diabetes was 32.3% (p = 0.003) and 18.6% (p = 0.002), respectively.

CONCLUSIONS

Our meta-analysis indicated that glucocorticoid-induced hyperglycemia occurs fairly frequently and points to the need for the design of prospective, randomized, controlled studies to further investigate and better understand this medical problem.

Successful treatment of pemphigus vulgaris with the extensive mucocutaneous lesions in an elderly patient

Introduction:

Pemphigus vulgaris (PV) is a chronic and infrequent autoimmune mucocutaneous disease that is characterized by the loose blisters and erosions on the skin and mucous membrane. Middle-aged adults are affect most frequently and the elderly and juvenile cases are infrequent. Herein, we reported a case of pemphigus vulgaris in an elderly patient.

Case Presentation:

We reported a case of pemphigus vulgaris in a 79-year-old patient with the extensive mucocutaneous lesions. We also reviewed the literature in MEDLINE with keywords such as pemphigus vulgaris, elderly, mucocutaneous lesions, oral lesions, and treatment.

Discussion:

We have to stress that the importance of this case report is its presentation in an elderly patient, as the frequent age of presentation in the Iranian patients is the middle age. On the other hand, PV occurs rarely, thus, the reporting of any rare case with some exceptions is important.
