The unusual association of Graves' disease, chronic spontaneous urticaria, and premature ovarian failure: report of a case and HLA haplotype characterization

Prevalence of Autoimmune and Autoinflammatory Diseases in Chronic Urticaria: Pathogenetic, Diagnostic and Therapeutic Implications

Chronic spontaneous urticaria (CSU) is defined as the almost daily occurrence of widespread wheals, angioedema, or both, for more than 6 weeks. It affects 1-2% of the general population, with a higher prevalence in female patients, and is more frequent patients over 20 years of age. More than half of all cases of chronic idiopathic urticaria are thought to occur due to an autoimmune mechanism, specifically the production of autoantibodies against the high-affinity immunoglobulin E (IgE) receptor (FcεRI). The quality of life in these patients is often greatly compromised, also due to the onset of comorbidities represented by other autoimmune diseases, such as thyroid disease, rheumatoid arthritis, systemic lupus erythematosus, Sjögren's syndrome, celiac disease, and type 1 diabetes, among others. This review aimed to analyze the close correlation between CSU and some autoimmune and autoinflammatory diseases, in order to encourage a multidisciplinary and multimorbid approach to the patient affected by CSU, which allows not only control of the natural course of the disease, but also any associated comorbidities.

An adolescent girl with premature ovarian failure, Graves' disease, and chronic urticaria: a case report

BACKGROUND

Premature ovarian failure is characterized by amenorrhea, hypoestrogenism, and hypergonadotropinism, and occurs in women under 40 years of age. The prevalence of premature ovarian failure in women younger than 20 years of age is only 0.01%. Immune disorders are one of the causes of premature ovarian failure. Graves' disease and chronic urticaria are also associated with immune disorders.

CASE PRESENTATION

We report a case of a 15-year-old Han Chinese girl with premature ovarian failure complicated by Graves' disease and chronic urticaria. She experienced menarche at 13 years of age and presented with amenorrhea after 7 months of irregular menstruation. Laboratory examinations indicated hypoestrogenism and hypergonadotropinism. Ultrasound imaging revealed that her uterus and ovaries were small in size. Gene and antibody tests related to premature ovarian failure returned negative results. Both thyroid peroxidase autoantibody and thyrotropin receptor antibody were positive. After reviewing the literature on the relationship between these three diseases and immune disorders, our patient was diagnosed as having atypical autoimmune polyglandular syndrome. After taking small doses of estrogen for 6 months, the size of her uterus increased, and her psychological anxiety was relieved.

CONCLUSIONS

We report a case of an unusual association of premature ovarian failure, Graves' disease, and chronic urticaria. This case presents an atypical combination of adolescent autoimmune polyglandular syndrome, which is worthy of the attention of clinicians and presents an important lesson for them. Our case highlights that premature ovarian failure in adolescents requires long-term follow-up and medical treatment as well as psychological counselling.

Autoimmune comorbidity in chronic spontaneous urticaria: A systematic review

BACKGROUND AND OBJECTIVE

Numerous autoimmune diseases (AIDs) have been linked to chronic spontaneous urticaria (CSU). Here, we provide the first extensive and comprehensive evaluation of the prevalence of AIDs in patients with CSU and vice versa.

METHODS

A Pubmed and Google Scholar search was performed to identify studies reporting the prevalence of various AIDs in CSU and vice versa published before April 2017.

RESULTS

The prevalence of individual AIDs in CSU is increased (≥1% in most studies vs ≤1% in the general population). AIDs with relatively high prevalence in the general population are also quite common in CSU patients, whereas those with low prevalence remain a rare finding in CSU. The rates of comorbidity in most studies were ≥1% for insulin-dependent diabetes mellitus, rheumatoid arthritis (RA), psoriasis and celiac disease (CD), ≥2% for Graves' disease, ≥3% for vitiligo, and ≥5% for pernicious anemia and Hashimoto's thyroiditis. Organ-specific AIDs are more prevalent in CSU than systemic (multiorgan or non organ-specific) AIDs. >2% of CSU patients have autoimmune polyglandular syndromes encompassing autoimmune thyroid disease (ATD) and vitiligo or pernicious anemia. Antithyroid and antinuclear antibodies are the most prevalent AID-associated autoantibodies in CSU. >15% of CSU patients have a positive family history for AIDs. The prevalence of urticarial rash in AID patients is >1% in most studies. This rash is more prevalent in eosinophilic granulomatosis with polyangiitis, ATD, systemic lupus erythematosus, RA and CD.

CONCLUSIONS

CSU patients have an increased risk of AIDs, especially adult female patients and those with a positive family history and a genetic predisposition for AIDs, who should be screened for signs and symptoms of AIDs.
