ABSTRACT
BACKGROUND AND AIM: The aim of this study is to evaluate the clinical, biological and hematological profiles of autoimmune hemolytic anemia (AIHA) in children and to specify its etiologies, therapeutic modalities, and treatment responses. METHODS: This is a 14-year retrospective study of AIHA cases collected at the department of pediatric emergency and reanimation of Hedi Chaker University Hospital in Sfax. We included patients under 14 years old with clinical and biological features of hemolysis and a positive direct antiglobulin test (DAT). The selected patients' demographic characteristics, physical signs, laboratory findings, and treatment responses were recorded. RESULTS: Thirteen cases of AIHA were collected, including 8 girls and 5 boys. The median age at diagnosis was 4 years and 6 months (range: 8 months to 13 years). Consanguinity was reported in 6 cases and 4 patients had a previous infection history. The onset of AIHA was progressive in 9 cases, marked by an anemic syndrome and hemolysis symptoms in 6 and 8 cases, respectively. The clinical triad (pallor, jaundice and splenomegaly) was found in only 4 cases. At the time of diagnosis, the median hemoglobin (Hb) level was 6g/dL (range: 4.2 to 9.2g/dL), anemia was non-regenerative in 2 patients. Thrombocytopenia and neutropenia were noted in 5 and 1 patient, respectively. Peripheral smear examination showed spherocytosis in 2 cases. All the patients had a positive DAT. Of these, 10 were positive with IgG and 3 with both IgG and C3d. AIHA was secondary to other conditions in 9 patients: infection (3 cases), autoimmune disease (4 cases), and immunodeficiency (2 cases). All the patients received first-line corticosteroid therapy but only 8 of them required blood transfusions due to severe anemia. Complete remission was obtained in 7 cases. Corticosteroid resistance and dependence were noted in 1 and 2 cases, respectively. During evolution, additional therapy was indicated in 4 patients and it included cyclosporine A, azathioprine, and mycophenolate mofetil (MMF). After a median follow-up of 4.5 years, the cure rate was 80% and only 1 patient (a boy) died due to his underlying pathology. CONCLUSION: Our study highlights the rarity, severity, and heterogeneity of etiological contexts of AIHA in children. The therapeutic difficulties justify specific expertise in pediatric hematology.

Sjögren syndrome is uncommon in children and occurs most often in association with autoimmune diseases (secondary Sjögren syndrome). We describe the clinical and biological features of a 7-year-old girl with primary Sjögren syndrome revealed by recurrent parotiditis. CASE REPORT: A 7-year-old girl was referred for investigation of multiple episodes of parotid swelling since age 4 years, without systemic symptoms. The examination was unremarkable except for enlarged and painless parotid glands. Laboratory investigations and labial salivary gland biopsy revealed Sjögren syndrome without associated disease. Hydroxychloroquine was prescribed with clinical improvement. CONCLUSION: Recurrent parotiditis in children is an uncommon condition. The onset of parotid swelling at 5 years or over deserves screening for disimmune disorders, sarcoidosis, or Sjögren syndrome. Diagnosis of Sjögren syndrome is based on diagnostic criteria.

UNLABELLED: Neonatal renal candidiasis is an increasingly common condition affecting predominantly premature infants receiving neonatal intensive care or term infants with urogenital tract anomalies. CASE REPORT: a female infant was born by cesarian section at 30 weeks' gestation to a mother whose pregnancy had been complicated by rupture of membranes for 5 days. The infant was admitted at birth, maternofetal bacterial infection was suspected, and intravenous antibiotics were prescribed. The patient developed sepsis caused by Klebsiella pneumoniae at the age of 13 days. She was referred to our hospital at the age of 50 days because of renal abscess. At admission, the baby presented with hypothermia and abdominal distention. Renal ultrasonography findings were compatible with fungal disease. Blood, urine, and cerebrospinal fluid cultures were negative for fungi; however, galactomannan antigen blood levels were increased. Amphotericin B was administered for 6 weeks. End-organ evaluation of the heart, brain, and eyes did not demonstrate disseminated infection. The patient was discharged with a prescription for oral fluconazole and remained well at follow-up.
