OBJECTIVES:
To study the association between paroxysmal nocturnal hemoglobinuria (PNH) clone and immunosuppressive therapy (IST) in children with severe aplastic anemia (SAA).
METHODS:
A retrospective analysis was performed on the medical data of 151 children with SAA who were admitted and received IST from January 2012 to May 2020. According to the status of PNH clone, these children were divided into a negative PNH clone group (n=135) and a positive PNH clone group (n=16). Propensity score matching was used to balance the confounding factors, and the impact of PNH clone on the therapeutic effect of IST was analyzed.
RESULTS:
The children with positive PNH clone accounted for 10.6% (16/151), and the median granulocyte clone size was 1.8%. The children with positive PNH clone had an older age and a higher reticulocyte count at diagnosis (P<0.05). After propensity score matching, there were no significant differences in baseline features between the negative PNH clone and positive PNH clone groups (P>0.05). The positive PNH clone group had a significantly lower overall response rate than the negative PNH clone group at 6, 12, and 24 months after IST (P<0.05). The evolution of PNH clone was heterogeneous after IST, and the children with PNH clone showed an increase in the 3-year cumulative incidence rate of aplastic anemia-PNH syndrome (P<0.05).
CONCLUSIONS
SAA children with positive PNH clone at diagnosis tend to have poor response to IST and are more likely to develop aplastic anemia-PNH syndrome.

A 34-year-old lady presenting with features of cold agglutinin disease during the course of systemic lupus erythematosus is described. Cold antibody titer was very high (1 in 4096) with specificity for 'I' antigen. Even though she had poor prognostic factors like high titer of cold antibodies with low thermal amplitude, she responded well to prednisolone.

BACKGROUNDIron deficiency (ID) is still a great challenge to health care worldwide. Results of randomized controlled trials (RCTs) evaluating the effect of Helicobacter pylori (H. pylori) eradication on ID are contradictory. This study aimed to evaluate the effect of H. pylori eradication on ID with a meta-analysis of RCTs.
METHODSFive electronic databases were searched for RCTs evaluating the effect of H. pylori eradication on ID. Summary effects were assessed with the methods recommended by the Cochrane Collaboration.
RESULTSEight studies involving 800 participants were included in this meta-analysis. The overall analysis showed that H. pylori eradication accelerated the improvement of ferritin levels in ID people (mean difference (MD), 7.74 microg/L; 95%CI, 4.61 to 10.88; P < 0.00001). In a subgroup analysis, H. pylori eradication accelerated the improvement of ferritin levels one month (MD, 7.00 microg/L; 95%CI, 1.72 to 12.28; P = 0.009) and two months (MD, 9.80 microg/L; 95%CI, 2.22 to 17.40; P = 0.01) after the initiation of treatment. However, H. pylori eradication did not show a beneficial effect on the improvement of ferritin levels three months (MD, 7.20 microg/L; 95%CI, -3.25 to 17.65; P = 0.18), one year (MD, 10.17 microg/L; 95%CI, -1.00 to 21.34; P = 0.07) and forty months (MD, 1.00 microg/L; 95%CI, -0.57 to 2.57; P = 0.21) after the initiation of treatment. H. pylori eradication did not accelerate the improvement of hemoglobin concentrations in the overall analysis (MD, 0.38 g/dl; 95%CI, -0.45 to 1.22; P = 0.37). In a subgroup analysis, H. pylori eradication did not accelerate the improvement of hemoglobin concentrations one month (MD, -0.48 g/dl; 95%CI, -2.39 to 1.42; P = 0.62), three months (MD, -0.10 g/dl; 95%CI, -0.35 to 0.15; P = 0.44) and forty months (MD, 0.10 g/dl; 95%CI, -0.37 to 0.57; P = 0.68) after the initiation of treatment. However, H. pylori eradication accelerated the improvement of hemoglobin concentrations two months (MD, 1.96 g/dl; 95%CI, 1.48 to 2.44; P < 0.00001) and one year (MD, 0.37 g/dl; 95%CI, 0.08 to 0.65; P = 0.01) after the initiation of treatment.
CONCLUSIONSH. pylori eradication is likely to improve the absorption of oral ferrous. H. pylori infection may play some roles in the development of ID.

Autoimmunity is thought to play a central role in the pathogenesis of inflammatory bowel disease and associated extraintestinal manifestations. Autoimmune hemolytic anemia associated with ulcerative colitis is a rare occurrence. No more than 50 cases have been described in the international literatures, and only 2 cases reported in Korea. A 29-year-old woman who was diagnosed as ulcerative colitis two years ago was complicated with autoimmune hemolytic anemia, and did not respond to steroid therapy. Ultimately, total colectomy and splenectomy were carried out for the treatment of ulcerative colitis and hemolytic anemia. After the operation, anemia was resolved. We present the case with a review of literature.

OBJECTIVETo study the effect of treatment of renal anemia by combination of Bushen Jianpi Recipe (BJR, a Chinese experience recipe for supplementing Shen and supporting Pi) and low dosage erythropoietin (EPO), and the influence of treatment on change of serum tumor necrosis factor alpha (TNF-alpha) so as to explore the possible mechanism of integrative Chinese and western medicine (ICWM) in treating renal anemia.
METHODSPatients with renal anemia were randomly divided into two groups, the ICWM group and the control group, symptomatic and supporting treatment such as dialysis, supplementing of ferrous, foliac acid and vitamin B12, was given to both groups. Additionally, to the ICWM group, 50 IU/kg of EPO subcutaneous injection for twice every week, and oral intake of BJR, one dose per day taken in two parts, were given, and to the control group, EPO alone, 50 IU/kg by subcutaneous injecting, 3 times per week, was given. The therapeutic course for two groups was 3 months. Blood levels of hemoglobin (Hb), hematocrit (Hct), TNF-alpha were measured before treatment and the therapeutic effect was observed.
RESULTSAfter treatment, the levels of Hb and Hct increased significantly in both groups (P < 0.01), comparison between the two groups in Hb and Hct after being treated for 3 months showed significant difference (P < 0.05). The serum level of TNF-alpha was markedly higher than normal range in both groups before treatment, it significantly lowered after treatment in the ICWM group (P < 0.05), but unchanged in the control group.
CONCLUSIONCombination of BJR and EPO could significantly inhibit the production of TNF-alpha, this may be an important factor for ICWM in effectively improving sensitivity to EPO.

The study was purposed to evaluate synergistic effect of beta-lactam antibiotics in drug-induced hemolysis. The general information, including primary diseases, therapeutic drugs, infection pathogens in 6 patients with pulmonary infection and unknown reason anemia were integrated and analyzed. The leukocyte and reticulocyte counts, total bilirubin (TB), direct bilirubin (DB), fasting blood glucose (Glu in peripheral blood) were all determined by conventional method. At the same time, the erythrocyte direct antiglobulin test (DAT), complement fixation test (CFT), cell culture and smear examination were carried out. The antibodies in plasma were also detected by indirect antiglobulin test (IAT). The result showed that levels of WBC, TB, DB, Glu and reticulocyte in six patients treated with beta-lactam antibiotics were raised remarkably. DAT was strongly positive, but no RBC antibodies were detected in the plasma by IAT. The binding of red cells by monocytes or lymphocytes was great, and the hemolysis of red cells by alexin not appeared. After stopping above-mentioned beta-lactam antibiotic administration, patient's WBC, TB, DB, and Glu levels returned to normal values. Furthermore, DAT test result turned to negative. It is concluded that beta-lactam antibiotics lead to drug-induced hemolysis by non-specific adsorption of some proteins onto RBC surface, and their proteins may be considered as direct cause for this hemolysis.
