Autoimmune hemolytic anemia occurs due to the accelerated destruction of erythrocytes as a result of the dysfunction of immune system cells, which produce antibodies against the normal antigens of the membrane of hematopoietic cells. One of its causes is systemic lupus erythematosus.
We present a case of a 20-year-old patient who was hospitalized with acute autoimmune hemolytic anemia, having been diagnosed with SLE at the age of 18 years. At the onset of the disease, hemolytic anemia was a differential diagnostic challenge.
The differential diagnosis between primary and secondary autoimmune hemolytic anemia (AIHA) was an important step. The presence of antinuclear antibodies (ANA Hep2, Anti-dsDNA, Anti-cardiolipin, Anti-phospholipids, anti-Ro, Anti-Sm B) were important arguments in making the diagnosis. The relapse of AIHA was caused by inadequate treatment, due to a lack of compliance. Pulse therapy combined with methylprednisolone and cyclophosphamide successfully resolved the AIHA.
Hematological abnormalities are commonly seen in SLE patients, but hemolytic autoimmune anemia is a rare condition. A timely diagnosis of the cause of hemolytic anemia and proper treatment of lupus by correcting autoimmune disorders are crucial in disease management. Pulse therapy combined with corticosteroids and immunosuppressants is effective in acute relapses of hemolytic anemia.
Pachydermoperiostosis (or primary hypertrophic osteoarthropathy) is a rare genetic disease that usually begins in childhood or adolescence, is characterized by certain clinical signs (pachydermia, periostosis, drum sticks) that gradually progress over many years until the disease stabilizes. Currently, there are 2 genes in which mutations are associated with the development of pachydermoperiostosis - HPGD and SLCO2A1. The functions of these genes are not fully understood, but their influence on the metabolism of prostaglandin E2 is known.
We present a case of a 20-year-old patient mistakenly diagnosed as juvenile idiopathic arthritis. Symptoms on admission to the hospital: pain accompanied by swelling in the hands and feet, arthralgias in the talocrural joints, knees with slight swelling, paresthesia in the extremities, hyperhidrosis, fatigue. Clinical and paraclinical examinations confirmed the diagnosis of pachydermoperiostosis.
Pachydermoperiostosis should be considered as a differential diagnosis when a patient presents with hypertrophic osteoarthropathy and acromegalic features.
