Granulomatosis with polyangiitis and pregnancy: A case report and review of the literature

The association of granulomatosis with polyangiitis and pregnancy is rare and therapeutic options are limited by the risk of teratogenicity and fetotoxicity. There is a paucity of published literature to guide clinical decision-making in these cases. We report the case of a 26-year-old woman with no medical history who presented at 21 weeks of gestation with a bilateral sudden loss of hearing and erosive rhinitis. The diagnosis of granulomatosis with polyangiitis was confirmed radiologically and biologically. Corticosteroids were not enough to stabilize the disease and she received intravenous immunoglobulins with remission. A successful delivery of a healthy male newborn was done at 36 weeks. A review of all published literature on granulomatosis with polyangiitis in pregnancy between 1970 and 2017 is presented. Trial registration: Not applicable.

Tocilizumab for the treatment of birdshot uveitis that failed interferon alpha and anti-tumor necrosis factor-alpha therapy: two cases report and literature review

Biotherapies appear as potential drugs for the treatment of inflammatory noninfectious uveitis. In this report, we show that tocilizumab, an anti-IL-6 agent, greatly improved two patients with birdshot chorioretinopathy refractory to conventional immunosuppressive drugs, interferon α2a, and anti-TNFα agents. After a follow-up of 22 months, patients exhibited an improvement of both visual acuity and macular edema. A corticosteroid-sparing effect was achieved in both cases.

[Psoriatic arthritis during rituximab treatment of granulomatosis with polyangiitis: a new paradoxical side effect?]

INTRODUCTION

Rituximab is a monoclonal antibody targeting the CD20 molecule of the B lymphocyte. Its efficacy has been recently reported in ANCA-associated vasculitis. We report a case of psoriatic arthritis that occurs during a treatment with rituximab in granulomatosis with polyangiitis.

CASE REPORT

A 66-year-old woman, without past history of psoriasis, presented with a relapsing granulomatosis with polyangiitis in July 2010 with sinus and lung involvement. Treatment with rituximab was started, allowing a complete remission in 6 months. Two months after the first two infusions of rituximab she developed asymmetric arthritis of 3 distal interphalangeal joints. A few months later, the clinical presentation showed asymmetrical arthritis of the hands and wrists and dactylitis. Standard radiographs and MRI showed an inflammatory impairment according with psoriatic arthritis.

CONCLUSION

Accountability of rituximab was retained in the development of the disease given the chronology of psoriatic arthritis development. It may be a paradoxical reaction, by analogy to those observed in anti-TNFα.

Pneumopathie avec bactériémie à Yersinia enterocolitica chez un patient diabétique porteur de l'antigène HLA-B27

INTRODUCTION

We report a new case of pneumonia and bacteremia due to Yersinia enterocolitica (YE) in a diabetic patient with HLA-B27 positive spondylarthritis.

OBSERVATION

A 75-year-old man was admitted for a pneumonia. He was suffering from HLA-B27 positive spondylarthritis and stable diabetes mellitus. Amoxicillin with clavulanic acid was ineffective. Two blood and stool cultures were positive for YE. There was no evidence of septic metastases, immunodepression and iron overload. Outcome was uneventful after 21 days of ofloxacin.

CONCLUSION

YE pneumonia is rare. In this patient, diabetes mellitus and spondylarthritis with HLA-B27 may have played a role in the infection but their imputability remain questionable.

Intérêt de la tomographie par émission de positons couplée au scanner dans la maladie d'Erdheim-Chester

INTRODUCTION

Erdheim-Chester disease is a rare non-Langerhans form of histiocytosis. We report the use of combined fluorodeoxyglucose positron emission tomography and computed tomography (18F-FDG PET-CT) in this disease.

EXEGESIS

Three men, aged from 55 to 74 years with confirmed Erdheim-Chester disease were included. 18F-FDG PET-CT allowed to detect visceral and vascular involvement of the disease which were overlooked with CT-scan or magnetic resonance imaging: left common carotid and ilio-femoral artery in one patient, coronary, femoral and tibia in the second, aortic, common carotid, femoral and mandibula in the remaining patient. Also, sequential 18F-FDG PET-CT was useful to appreciate treatment efficiency (decrease hyperfixation) and decide treatment modification (interferon alpha).

CONCLUSION

18F-FDG PET-CT combined imaging allows to assess the extent of involvement in Erdheim-Chester disease. 18F-FDG PET-CT may be also a useful tool in the management of Erdheim-Chester disease.

[Liver involvement in hereditary haemorrhagic telangiectasia (Rendu-Osler-Weber disease). Report of one case and review of the literature]

INTRODUCTION

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular dysplasia; mutations in at least three genes (ENG, ACVRL1 et MADH4), which are components of transforming growth factor (TGF)-beta, may lead to the clinical picture of HHT. HHT is a multisystemic angiodysplasia, resulting in multiple vascular malformations, involving notably the liver.

EXEGESIS

We report the case of a patient with anicteric cholestasis, revealing HHT. Abdominal CT-scan revealed hepatic artery dilation and multiple arteriovenous fistula. At 2-year follow-up, the patient exhibited liver involvement-associated high output cardiac insufficiency.

CONCLUSION

Liver involvement is frequent in HHT, occurring in 8-31% of patients; it may lead to life-threatening complications, such as high output cardiac failure, portal hypertension or severe cholangitis. Abdominal Doppler ultrasonography is a non-invasive accurate method, suitable for first-line imaging of the liver in patients with HHT; it should be done in all patients, in order to detect HHT-related hepatic vascular malformations.

Subcutaneous fat necrosis of the newborn: a systematic evaluation of risk factors, clinical manifestations, complications and outcome of 16 children

BACKGROUND

Subcutaneous fat necrosis (SFN) of the newborn is a rare acute transient hypodermatitis that develops within the first weeks of life in term infants. It often follows a difficult delivery. Prognosis is generally good except for the development of hypercalcaemia in severe cases. Only several case reports or small patients series have been published.

OBJECTIVES

To evaluate risk factors, complications and outcomes of SFN in 16 consecutive patients seen from 1996 to 2002 in our Department of Paediatric Dermatology.

METHODS

On a case-report form created for the study, we recorded putative risk factors concerning the mother, pregnancy and delivery, clinical aspects of SFN, and early and late outcomes. The study was conducted in two stages: the first was a retrospective analysis of the observations and the second analysed data collected on children and their parents during a new consultation (n=10).

RESULTS

All the children were born at term. Lesions appeared a mean of 4 days after delivery. Three-quarters of the children had diffuse SFN. Risk factors identified were newborn failure to thrive (12/16), forceps delivery (7/16), maternal high blood pressure (3/10) and/or diabetes (2/10), and newborn cardiac surgery (1/16). Putative novel risk factors were macrosomia (7/16), exposure to active (4/10) or passive (3/10) smoking during pregnancy, putative or known maternal, paternal or newborn risk factors for thrombosis (5/10), and dyslipidaemia (2/10). Complications were hypercalcaemia (9/16), pain (4/16), dyslipidaemia (1/16), renal insufficiency (1/16) and late subcutaneous atrophy (6/6).

CONCLUSIONS

This study on 16 newborns with SFN provides new information. Familial or newborn risk factors for thrombosis are frequent. Macrosomia, familial dyslipidaemia and smoking should be evaluated. The main complications identified were severe pain, hypercalcaemia and subcutaneous atrophy.

[Multinucleate cells angiohistiocytoma]

INTRODUCTION

Multinucleate cell angiohistiocytoma is a rare entity. We report two unusual cases of this lesion.

CASE REPORT

A 39 year-old man had presented since two years an arciform papular eruption of the forehead. A 40 year-old woman had a disseminated maculo-papular eruption since three years. Histological examination of skin samples of the two patients showed a dermal small vessel proliferation, associated with multinucleate cells, and confirmed the diagnosis of multinucleate cell angiohistiocytoma.

DISCUSSION

Our cases, typical histologically, have unusual clinical presentation (first case observed in a man, and the second in a disseminated form). Multinucleate cell angiohistiocytoma is a rare benign vascular proliferation individualized in 1985. Clinically, the lesion consists in small circumscribed papules. Acral sites and notably of the dorsum of the hands are the more frequent topography. It generally occurs in women aged over 50 years. Histologically, there is a dermal proliferation of capillaries and venules, and a fibrosis associated with the interstitial mononucleate cells and multinucleate cells.
