Therapeutic Efficacy of Leukocytapheresis in a Pregnant Woman with Refractory Adult-onset Still's Disease

Pregnancy-Associated Onset of Adult-Onset Still's Disease

Objective  This study aims to elucidate the clinical manifestations, diagnostic challenges, and management strategies of adult-onset Still's disease (AOSD) during pregnancy, leveraging a case series overview and a detailed case report from our center. Study Design  A comprehensive review of 21 published case reports on AOSD diagnosed during pregnancy was conducted, alongside a detailed case report of a patient diagnosed and managed at our center. This study emphasizes the importance of recognizing AOSD in pregnant patients, outlines the therapeutic challenges encountered, and discusses the potential complications arising from the disease and its treatment. Results  The onset of AOSD during pregnancy predominantly occurs in the first or second trimester, with a polycyclic disease course observed in most cases. Management primarily involves corticosteroids and immunosuppressive medications, balancing the disease control with potential pregnancy complications. The case report highlights the complex interplay between AOSD, hemophagocytic lymphohistiocytosis, and pregnancy, illustrating a multidisciplinary approach to management that ensured favorable maternal and fetal outcomes despite the significant challenges. Conclusion  AOSD presents unique diagnostic and therapeutic challenges during pregnancy, requiring careful consideration of maternal and fetal health. Early diagnosis, a multidisciplinary approach to care, and judicious use of immunosuppressive therapy are critical for managing AOSD flares and associated complications. Further research is necessary to optimize care for this rare condition in the context of pregnancy.

Adult-onset Still's Disease during Pregnancy Treated with Tocilizumab

A 28-year-old woman exhibited a spiking fever, arthritis, and liver disfunction when she was 22 weeks pregnant. She was diagnosed with adult-onset Still's disease (AOSD). As her condition was resistant to corticosteroid therapy, tocilizumab (TCZ) was selected. The TCZ treatment was effective, and she delivered a healthy child while receiving TCZ treatment. Cases in which AOSD first arises during pregnancy are rare, and there have been no reports of TCZ treatment for AOSD being initiated during pregnancy. Although the safety of TCZ treatment during pregnancy has not been established, it may be effective against severe AOSD that develops during pregnancy.

A case of recurrence of adult-onset Still's disease in the third trimester: a case report and literature review

Background

Adult-onset Still’s disease (AOSD) is a self-inflammatory disease showing macrophage and neutrophil activation by inflammatory cytokines such as TNF-α, IL-6, and IL-18. Although some cases with the flare of AOSD during pregnancy have been reported, most had flares in the first or second trimester and few had flares in the third trimester. In this report, we present the case of a patient with recurrent flare of AOSD in the third trimester and discuss the management of AOSD in the third trimester with the review of previous literatures.

Case presentation

A 38-year-old woman in complete AOSD remission without medication presented with impaired liver function, low platelet count, mild fever, abdominal pain, splenomegaly, and elevated ferritin and IL-18 levels at 30 gestational weeks. Although the laboratory data and physical examination finding suggested HELLP syndrome or acute fatty liver of pregnancy and we considered the termination of her pregnancy, her fetus was in a reactive status. Considering her fetal status, some specific findings of AOSD, and her AOSD history, we and rheumatologists diagnosed her with AOSD recurrence and started systemic steroid therapy. In her clinical course, three flares of AOSD occurred, twice in the third trimester and once in postpartum; twice systemic steroid pulse therapies were then needed. Ultimately, a healthy infant was delivered transvaginally at 36 gestational weeks spontaneously.

Conclusions

Specific findings of the flare of AOSD such as fever, splenomegaly, elevated ferritin and IL-18 levels, and fetal status could be useful findings for differentiation from HELLP syndrome and AFLP in the third trimester. With the careful management supported by rheumatologists, patients complicated with the flare of AOSD may continue their pregnancy longer than we expected.

Pregnancy Outcomes in Patients With Adult-Onset Still's Disease: A Cohort Study From China

Objective: Adult-onset Still's disease (AOSD) is an autoinflammatory disease with a higher prevalence rate in young females. The purpose of this study is to investigate whether AOSD has an adverse impact on pregnancy outcomes, or conversely exacerbated by pregnancy.

Methods: The outcomes of 191 pregnancies were evaluated in 86 female patients with AOSD. The generalized linear mixed model and propensity score matching method were conducted to evaluate the influence of AOSD on pregnancy outcomes. A dependent sample sign test was applied to assess the impact of pregnancy on the relapse of AOSD.

Results: The results showed that the post-AOSD group had a lower proportion of normal delivery (25.0 vs. 52.4%, p = 0.036) and a higher proportion of spontaneous abortion (STA) (18.8 vs. 0.6%, p = 0.002) compared with the pre-AOSD group. Moreover, pregnancy after being diagnosed with AOSD was a significant high risk factor of STA (adjusted OR = 4.577, 95% CI: 4.166–845.119; p = 0.003). Disease flare upon conception was observed in one of 16 post-AOSD pregnancies (p = 1.000). There were 11 patients with new-onset AOSD during gestation or postpartum, among which five (45.4%) evolved into the polycyclic course.

Conclusions: AOSD patients might suffer from a higher risk of STA, however, pregnancy might not be related with the exacerbation of diagnosed AOSD. New-onset AOSD during gestation or postpartum tend to evolve into the polycyclic course.

Adult onset Still's disease occurring during pregnancy: Case-report and literature review

INTRODUCTION

Adult onset Still's disease is a rare affection classified among non-hereditary autoinflammatory diseases. We here report a case of AOSD revealed during pregnancy with a life-threatening presentation along with a review of 19 cases from literature.

CASE

A 38-years old woman was treated in our department for diffuse systemic sclerosis and associated Sjögren syndrome. She was pregnant and presented with acute fever and arthralgias. Laboratory data revealed mild liver cytolysis but a large screening for infectious and auto-immune diseases was negative and hepato-biliar imaging was normal. Ferritin levels were at 41 000 ng/mL with glycosylated ferritin less than 5%. The diagnosis of AOSD was stated and because of persistent fever and polyarthralgias, after exclusion of active infection, steroids were started (prednisone 1 mg/kg) associated with colchicine, which allowed clinical remission and C-reactive protein significant decrease.

CONCLUSION

Pregnancy-revealed AOSD appears to be a specifical subset of the disease with a systemic course, flares on first and second trimester, obstetrical complications such as prematurity and IUGR sometimes leading to life-threatening situations requiring parenteral corticotherapy and intravenous immunoglobulins.
