Full haematological data were available on 22 of the first 30 patients with proven acquired immunodeficiency syndrome (AIDS) admitted to Johannesburg Hospital before July 1987. Reversal of the helper/suppressor T-cell ratio was present in all cases and polyclonal hypergammaglobulinaemia in 85% of cases. Sixty-eight per cent of patients were anaemic, 55% leucopenic, 77% lymphopenic and 23% thrombocytopenic. Four patients (out of 12 tested) exhibited a positive Coombs test (25%) and 2 patients (out of 13 tested) had a circulating lupus anticoagulant (15%). Bone marrow examination revealed all patients to be either normo- or hypercellular. Three patients exhibited haemophagocytosis. Given the increasing incidence of AIDS and the frequency of haematological abnormalities in this condition, the practising clinician should have a high index of suspicion when confronted by any unexplained haematological abnormality.

In order to investigate the clinical characteristics of hematological abnormality in patients with systemic lupus erythematosus (SLE) and inquire into the basis for differential diagnosis, the hematological data of 92 cases with lupus erythematosus-related hematological disorder (SLERHD) were retrospectively analyzed by use of SPSS/PC software. The results showed that these patients were short of specificity in clinical manifestation and hemogram, however, all cases possessed multiple SLE-related autoantibodies, increase of serum globulin level and varying extent dermal and arthral signs. The incidence of primary or initial symptom in the 92 cases was as follow: 65 anemia (72.8%), 39 purpura (42.4%), 17 hemolytic anemia (18.5%), 56 leukopenia (60.9%), 54 thrombocytopenia (58.7%), and 41 pancytopenia (44.6%). The bone marrow examinations showed that the cellularity of nucleated cells was mostly normal, and active proliferation in 57 cases (61.9%) and hypercellularity in 35 cases (38.1%); the G/E ratio was normal in majority, and G/E ratio > 3 in 59 cases (64.1%) and < 3 in 33 cases (35.9%) and G/E < 1 in 17 cases with hemolytic anemia Coombs' test positive; megakaryocyte counts were normal in 11 cases (11.9%), increase in 80 cases (86.9%) and lower than 7/marrow smear in 1 case (1.1%). Neutrophil alkaline phosphatase staining was negative in all of the cases. From above data it is concluded that patients with SLERHD are varied in clinical and blood pictures, but all patients are provided with multiple SLE-related autoantibodies, globulinemia and dermal and arthral signs. It is easy to identify SLERHD from aplastic anemia, myelodysplastic syndrome, idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia and Evans' syndrome by comprehensive and detailed clinical and laboratory examinations.

Thrombotic thrombocytopenic purpura (TTP) is a rare and life-threatening hematological abnormality characterized by thrombocytopenia and microangiopathic hemolytic anemia, with neurological abnormalities and/or renal disease. TTP has been rarely reported in juvenile systemic lupus erythematosus (JSLE) patients and, to our knowledge, its prevalence in a paediatric lupus population has not been studied. Therefore, from January 1983 to December 2010, we reviewed the charts of 5,508 patients followed-up at the Paediatric Rheumatology Unit of our university hospital. We identified 279 (5.1%) JSLE cases that met the American College of Rheumatology classification criteria. Two (0.7%) of them had TTP, both at JSLE onset, and were described herein. Both patients had fever, microangiopathic hemolytic anemia (with schistocytes in blood smears), and thrombocytopenia. The male patient had hemiparesis and proteinuria and the female patient had persistent headache and hematuria. Both were treated with intravenous methylprednisolone and courses of plasma exchange therapy at TTP diagnosis. After treatment, TTP did not recur and their hematocrit, platelet count, and lactic dehydrogenase remained normal. In conclusion, TTP is a rare and severe manifestation at JSLE onset. The case reports reinforce the importance of early diagnosis and early aggressive treatment for patients with TTP, due to its high morbidity.

BACKGROUND This study aimed to estimate the point prevalence of myositis and identify associated variables of myositis in systemic lupus erythematosus (SLE). MATERIAL AND METHODS Clinical date of patients hospitalized with lupus at the First Affiliated Hospital of Anhui Medical University and Anhui Provincial Hospital were collected. Patients were defined as having myositis if they reported the presence of persistent invalidating muscular weakness combined with increased levels of creatine phosphokinase (CPK) and abnormal electromyography (EMG). RESULTS The study sample comprised 1701 lupus patients, of which 44 had myositis. Patients with SLE-associated myositis are more likely to have skin rash, alopecia, pericarditis, vasculitis, anti-Sm, anti-RNP, anti-dsDNA, thrombocytopenia, leukopenia, low C3, low C4, high erythrocyte sedimentation rate (ESR), high D-dimer, and active disease. Multivariate logistic regression found positive associations between leukopenia, alopecia, and active disease with myositis. Negative associations between myositis with the use of corticosteroids or immunosuppressive drugs were revealed in univariate and multivariate analysis. CONCLUSIONS The point prevalence of myositis was 2.6% in SLE patients. The significant association of alopecia, leukopenia, and active disease with myositis suggests that organ damage, hematological abnormality, and high disease activity promote the progression of myositis in lupus patients.

To estimate the mortality and describe the causes of death in a large multicenter cohort of hospitalized patients with SLE in China. This was a retrospective study of a nationwide SLE cohort (10 centers, 29,510 hospitalized patients) from 2005 to 2014 in China. Standardized mortality ratios (SMRs) were calculated for all death and were stratified by sex and age. Chi-square test was used to determine whether the major causes of death vary in age, sex, duration of SLE, disease activity, or medications. Comparison between dead patients and survival controls was used to identify the risk factors for mortality. Logistic regression analysis was used to evaluate the risk factors for mortality. A total of 360 patients died during the study period, accounting for 1.22%. The overall SMR was 2.13 (95% CI 1.96, 2.30), with a particularly high SMR seen in subgroups characterized by younger age. Infection (65.8%) was the most common cause of death, followed by lupus nephritis (48.6%), hematological abnormality (18.1%), neuropsychiatric lupus/NPSLE (15.8%), and interstitial pneumonia (13.1%). Cardiovascular disease and malignancy contributed little to the causes of death. Infection, in particular severe pulmonary infection, emerged as the foremost risk factor for mortality, followed by lupus encephalopathy. However, lupus nephritis and hematological abnormalities occurred more frequently in survival patients. SLE patients at a younger age of diagnosis have a poorer prognosis. Infection dominated the causes of death in recent China. Ethnicity and medications might account for the differences in causes of death compared with western populations.
