Introduction: haemolytic anaemia (HA) is defined as a decrease in haemoglobin (Hb) levels below baseline due to excessive and premature destruction of red blood cells (RBCs) in the periphery resulting in a shortened life span of less than 120 days. Haemolysis can be corpuscular or extra-corpuscular. The aim of our study was to investigate the factors associated with it for optimal management of patients hospitalised in internal medicine at the Douala General Hospital (DGH). Methodology: We conducted an analytical cross-sectional study, including all patients admitted to the internal medicine department of the DGH from 11 February to 20 May 2022, and excluding patients with non-compliant samples. The search for haemolytic anaemia was carried out by means of blood count, reticulocyte count, blood smear, unconjugated bilirubin, lactate dehydrogenase and direct Coombs test. Sociodemographic, clinical and biological parameters were collected and analysed. Correlation was defined for a p value 0.05. Results: This study included 147 patients, 50.34% of whom were men, for a sex ratio of 1.01. The mean age was 52 ± 17.9 years. The most represented age group was 56 - 70 years (n = 49;33%) with extremes from 15 to 90 years. We counted 29.3% cases of haemolytic anaemia (HA) and 13.9% cases of autoimmune haemolytic anaemia (AIHA). haemolytic anaemia (HA) was present in 54.14% of men for a sex ratio of 1.38;the most represented age group was 40 - 55 years, 37.2%. HA was associated with jaundice (OR: 3.74, CI: [1.70 - 8.22], p = 0.001), HIV - AIDS (OR: 2.72, CI: [0.98 - 7.53], p = 0.05), thrombocytopaenia (OR: 3.53, CI: [1.58 - 7.89], p = 0.02). LDH was elevated (OR: 2.86, CI: [1.30 - 6.26], p = 0.00) as well as elevated reticulocyte count (OR: 3.84, CI: [1.75 - 8.44], p = 0.01). Unconjugated bilirubin was elevated in all these patients. In multivariate analysis, factors associated with HA were a history of HIV/AIDS, jaundice, thrombocytopaenia and elevated reticulocyte count. Conclusion: Hemolytic anaemia is common in internal

Late Onset Combined Immune Deficiency (LOCID) Revealed by a haemolytic anaemia in a Child: A Case Report

Open Journal of Pediatrics 2023年第3期13卷 347-351页

Variable Common Immune Deficiency (VCID) is a very heterogeneous condition both clinically and immunologically. It is a group of molecular abnormalities responsible for a defect in antibody production leading to hypogammaglobulinemia often associated with autoimmune and/or lymphoproliferative manifestations. Late Onset Combined Immune Deficiency (LOCID) is a type of Variable Common Immune Deficiency (VCID) defined by a defect in antibody production (IgG and IgA ± IgM type), profound CD4 T-cell lymphopenia and frequent opportunistic infections. LOCID has been considered as a distinct entity from VCID due to its particular clinical and immunological profile.

haemolytic anaemia Following High Dose Intravenous Immunoglobulin Treatment for Epidermolysis Bullosa Acquisita

引用

Pharmacology & Pharmacy 2016年第1期7卷 25-28页

作者： Sarah Madeline Brown Philip Jeremy Hampton Department of Dermatology The Newcastle upon Tyne Hospitals NHS Foundation Trust Royal Victoria Infirmary Newcastle UK

Background: Epidermolysis bullosa aquisita (EBA) is a severe acquired blistering skin disease that is often resistant to prednisolone but can respond well to intravenous immunoglobulin infusion (IVIg). Main Observations: We describe the case of a 35 years old male patient with EBA who developed clinically significant haemolytic anaemia with a drop in Hb from 15.3 g/dL to a nadir of 8.4 g/dL within 5 days post IVIg infusion. The patient was blood group A and the IVIg batch was found to have a high titre of anti-A immunoglobulin. Conclusions: IVIg is an effective treatment for EBA. Haemolysis associated with IVIg has not previously been reported in the dermatology literature but review of data from other specialties shows that the problem is well recognised. Dermatologists using IVIg should be aware of this potential complication and patients should be consented appropriately and warned about this potential side effect.
