Burden of cytopaenias among HIV positive pregnant women at the University College Hospital, Ibadan

Introduction: Few studies have examined cytopaenia among HIV positive pregnant women.Objectives: To assess burden of cytopaenia among HIV positive pregnant women.Methodology: This cross-sectional study of women on HAART <6months, defined anemia as hematocrit <33%, leucopenia as total white blood cell count <3,000 cells/mm3 and thrombocytopenia as absolute platelet count <100,000 cells/mm3. Univariate and bivariate analyses were performed.Results: Over 8 years, of 1,197 women, the mean age was 29.02(±5.4) years and mean gestational age 25.9(±8.1) weeks. Prevalence of anaemia was 76.8%, leucopaenia 6.9% and thrombocytopenia 4.7%. The mean haematocrit was 28.5%(±4.5); median white blood count 5,500/mm3 ; median platelet count 200,000/mm3 and median CD4 323 cells/mm3.Mean haematocrit was highest (29.7%±5.3) in women in the first trimester but lowest (28.4% ±4.6) in women in second trimester (p=0.04). Compared with earlier trimesters, women in the third trimester had higher median white blood count (5,600 cells/mm3), higher neutrophil (61.0% ±11.2) but lower lymphocytes(28.3%± 9.2) (p=0.18; 0.00, 0.00). Median absolute platelet count was highest (206,000 cells/mm3) in the first trimester but lowest (195,000 cells/mm3) in third trimester (0.04). Women with lower CD4 had higher prevalence of cytopaenias.Conclusion: Cytopaenias are not uncommon in this population especially with lower CD4

Fulminant hepatitis B virus (HBV) infection in an infant following mother-to-child transmission of an e-minus HBV mutant: Time to relook at HBV prophylaxis in South African infants

The prevalence of hepatitis B virus (HBV) infection in pregnant women is high in South Africa (SA), yet prophylaxis to prevent mother-to-child transmission (MTCT) falls short of international recommendations. We describe a 10-week-old infant who developed fulminant hepatic failure following MTCT. The mother was hepatitis e-antibody positive and had a viral load of only 760 IU/mL. Genetic analysis of virus from mother and infant showed that both had the G1896A mutation in the preC/C gene, which truncates hepatitis e antigen (HBeAg) during translation, causing an HBeAg-negative phenotype. HBeAg attenuates antiviral immune responses, and its absence was probably responsible for the infant’s fulminant hepatitis, due to an uncontrolled immune attack on infected liver cells. Pregnant women are not tested for HBV infection in SA and MTCT rates are unknown. Addition of a birth dose of vaccine, HBV screening of pregnant women and antiviral prophylaxis to positive mothers should be prioritised

Co-existing sickle cell anaemia and inflammatory bowel disease: case report and review of the literature

Sickle cell anaemia (SCA) is a chronic haemolytic anaemia associated with vaso-occlusive painful crises which may affect several systems including the gastro-intestinal system, resulting in abdominal pain. The concurrence of inflammatory bowel disease and haemoglobinopathy is rare. No previously reported concurrent cases of both SCA and ulcerative colitis (UC) in sub-Saharan Africa were found in the literature. A 16-year-old girl with concurrent SCA and UC is presented. She was admitted to University College Hospital, Ibadan with a 1-year history of recurrent peri-umbilical pain and bloody stools. These symptoms were mainly attributed to SCA at the referring hospital, and she was managed for chronic tropical diarrhoea without a remarkable clinical response. This case illustrates the concurrent presentation of SCA and ulcerative colitis which led to the missed and delayed diagnosis of ulcerative colitis
