Background: The psychiatric manifestations of Sjögren’s syndrome are often overlooked despite their prevalence. They can be revelatory of the disease and include anxiety, depression, dementia and, rarely, psychosis. Case description: We report a case of 18-year-old female in whom a major depressive syndrome revealed primary Sjögren’s disease, with a favourable outcome after treatment with rituximab. Conclusion: The diagnostic of Sjögren’s syndrome should be considered in patients who present with unexplained and refractory neuropsychiatric symptoms, even in the absence of sicca symptoms.

Background: Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, characterised by multi-organ affections. Haematological involvement is a common manifestation of SLE, consisting of autoimmune peripheral cytopenia. Autoimmune myelofibrosis (AIMF) is a rare cause of cytopenia in SLE; it could precede or be concurrent with the diagnosis of SLE. There are few studies that describe this association. Case description: We report a case of AIMF revealing the diagnosis of SLE in a 34-year-old female, presented with episodes of gingival bleeding associated with peripheral inflammatory polyarthralgia, photosensitivity and deterioration of general condition. Clinical examination revealed a soft pitting oedema in the lower limbs. Laboratory investigations showed a pancytopenia, inflammatory biological syndrome, with positive 24-hour proteinuria and anti-native DNA antibodies. A bone marrow biopsy showed diffuse myelofibrosis associated with maturation disorders and no tumour infiltrate. Renal biopsy revealed proliferative glomerulonephritis class III with immune deposits. Conclusion: The association of AIMF with SLE has been rarely reported, and it could be another cause for cytopenia in SLE.

Hypertrophic pachymeningitis (HP) is an uncommon condition characterised by focal or diffuse thickening of the dura mater. An increasing number of cases have been reported of its association with underlying connective tissue diseases. It is a rare complication in systemic lupus erythematosus (SLE) and might be the initial and sole clinical manifestation. We report a case of a 21-year-old man presenting with febrile meningeal syndrome and sphincter dysfunction. Physical examination showed malar rash and joint pain. Biological assessment revealed a regenerative normocytic normochromic anaemia, a leucopenia and a lymphopenia. The 24-hour urine protein was positive at 0.6 g. Immunological evaluation revealed positive antinuclear, anti-Sm and anti-dsDNA antibodies. Brain and spinal magnetic resonance imaging showed hypertrophic pachymeningitis. Cerebrospinal fluid biochemistry was within normal limits. Renal biopsy revealed a mesangial proliferative lupus nephritis. The diagnosis of SLE with neurologic and renal involvement was established, and the patient was treated with intravenous methylprednisolone pulse, followed by oral prednisone in association with azathioprine and hydroxychloroquine. Considering the persistence of symptoms and MRI lesions after 6 months, a treatment with rituximab was initiated with good evolution.

Introduction: Vitamin C deficiency (or scurvy) usually takes weeks to become apparent as cutaneous signs and impaired wound healing. Haemorrhagic pericarditis remains a rare complication of scurvy, which has never been reported as an isolated condition. We report the case of a haemorrhagic pericarditis revealing a vitamin C deficiency in a 56-year-old patient. Case description: A 56-year-old woman presented with a 2-week history of worsening chest pain and dyspnoea, with no significant medical history. Upon admission, the patient exhibited tachycardia, tachypnoea, low blood pressure, elevated jugular venous pressure, muffled heart sounds and multiple petechiae on her lower limbs. An ultrasound revealed a large pericardial effusion, and an emergency pericardiocentesis was performed, which yielded haemorrhagic fluid without atypical cells. An initial workup including haemoculture, PT and PTT, tuberculosis workup, autoantibodies, tumour markers and infectious disease was negative. A whole-body CT scan showed no evidence of tuberculosis or lymphoma. Additional testing showed that her vitamin C level was

Introduction: Myasthenia gravis is a rare autoimmune disease caused by autoantibodies directed against the synapses of the neuromuscular junction. Patient and methods: We report the case of a young patient with myasthenia gravis associated with Hodgkin's lymphoma. Results: A 22-year-old patient presented with a 2-month history of severe weakness associated with muscle fatigability and intermittent ptosis without dysphonia or respiratory signs. Clinical examination revealed generalized myasthenia. The EMG did not show post-synaptic block, and anti-acetylcholine receptor antibodies were elevated at 3 nmol/l (normal ?0.3 nmol/l). CT of the thorax showed an anterior medial mass. Immunohistochemistry of the mass revealed mixed cellularity Hodgkin’s lymphoma. Conclusion: The association of lymphomas with myasthenia gravis has been rarely reported.

Nous rapportons un cas d´exanthème maculo-papuleux apparu après une semaine de prise de l´hydroxychloroquine 400mg prescrite pour une atteinte articulaire d´un syndrome de Goujerot Sjögren primaire chez une patiente de 41 ans. Cette dernière était suivie pour une lésion glomérulaire minime idiopathique depuis plus d´un an, traitée efficacement avec la corticothérapie. Les exanthèmes maculo-papuleux ont régressé après avoir reçu l´hydrocortisone, la desloratidine et l´arrêt immédiat de l´hydroxychloroquine. Notre cas reflète l´importance d´insister sur la prescription à faible dose de l´hydroxychloroquine chez les sujets avec des pathologies préexistantes rénales et aussi l´intérêt de sensibiliser et d´éduquer les patients des effets secondaires de l´hydroxychloroquine.
