The number and maturation of circulating reticulocytes were measured in patients with
systemic lupus erythematosus
(
SLE
) and chronic renal failure (CRF) using an automated hematological analyzer (Technicon H*3 RTX) for their erythropoietic activities. Both
SLE
and CRF patients had increased reticulocyte numbers with a low degree of maturation. The
SLE
patients had no changes in mean reticulocyte corpuscular volume (MCVr) as compared to normal subjects (110.20 +/- 15.43 fl. in
SLE
and 110.39 +/- 5.09 fl. in normal), whereas CRF patients had significantly increased mean corpuscular reticulocyte volume (MCVr = 120.99 +/- 8.09 fl., p-value = 0.0019 as compared with normal). Three cases of
SLE
with nephrotic syndrome (NS) had high degree of MCVr (113.4, 125.0 and 133.1 fl., respectively). The renal involvement in
SLE
patients and CRF patients may associate with increased reticulocyte corpuscular volume.

Neuropsychiatric (NP) manifestations in patients with
systemic lupus erythematosus
(
SLE
) [NPSLE] and prognostic factors were studied in 91 patients. There were 98 NP episodes, of which 78 (79.6%) occurred within the first year of the disease. Twenty-six patients (6.7%) had NPSLE as an initial presentation of the disease. There were seizures in 53 episodes (54.1%), psychosis in 13 (13.3%), acute confusion state in 11 (11.2%), abnormal consciousness in 6 (6.1%), transverse myelitis in 6 (6.1%), peripheral neuropathy in 5 (5.1%), cerebral infarction in 2 (2.0%) and aseptic meningitis in 2 (2.0%). Most forms of NPSLE responded well to high dose corticosteroids. Anti-convulsant therapy could be discontinued within a median duration of 3 months after the
SLE
activity was under control, and without significant recurrence of seizures. The 5-year and 10-year survival rates of patients with NPSLE were 75.9% and 50.6%, respectively. Patients with NPSLE had significantly more cutaneous vasculitis and less arthritis than those without.

The anti-C1q antibody has been shown to be associated with
lupus
patients with renal involvement. We conducted a study to determine the relationship between the serum anti-C1q titer and the renal deposition of C1q. The serum anti-C1q was measured in 26 healthy controls and 47
systemic lupus erythematosus
(
SLE
) patients who were divided into 2 groups as non-nephritis and nephritis
SLE
. We analyzed the relationship between the anti-C1q titers and
SLE
, renal C1q staining and the WHO classification for lupus nephritis. The result revealed that the serum anti-C1q was present in 50.8% of the
SLE
patients, that its levels in those with renal involvement were significantly higher than in the normal control group (61.540 +/- 87.720 U/ml vs 15.750 +/- 2.530 U/ml, p = 0.005). Besides, the serum anti-C1q levels were higher in the patients with lupus nephritis with C1q deposition in the kidney tissue (66.038 +/- 91.141 U/ml vs 16.652 +/- 3.097 U/ml, p < 0.01). There seems to be evidence supporting that the autoantibody anti-C1q might play a pathogenic role in lupus nephritis.

Anti-nuclear antibody (ANA) negative
systemic lupus erythematosus
(
SLE
) occurs in about 4-13% of
SLE
cases. A small group of ANA negative
SLE
patients with positive anti-Ro antibodies usually present with typical vasculitic skin lesions which can be associated with photosensitivity, renal disease, congenital heart block or neonatal
lupus
. We present a case of a persistently ANA negative patient who presented with joint pain, rashes, mouth ulcer and alopecia. Clinical diagnosis of
systemic lupus erythematosus
was made even though ANA was negative. She was started on steroids and went into remission. Later, she developed several episodes of convulsions associated with fever and prominent vasculitic lesions. The patient was also found to have microscopic hematuria, proteinuria, anemia and thrombocytopenia. Renal biopsy showed lupus nephritis class 1B. Due to the prominent skin lesions, we performed anti-extractable nuclear antigens (ENA) antibodies test and anti-Ro turned out to be positive. The final diagnosis was ANA negative
SLE
(Ro
lupus
) with cutaneous, renal, musculoskeletal, hematological and cerebral Involvement.

A cross sectional study was conducted to determine the auto-antibody profile of Malay
SLE
patients in Kelantan, North East Malaysia and to correlate them with clinical presentations. Eighty-two Malay
SLE
patients who fulfilled the ARA criteria underwent the following tests: ANA, anti-dsDNA antibody, anti-ENA antibody and RF. The results revealed that ANA was positive in 91.5% of the patients, anti-dsDNA antibody in 53.7%, however, anti-ENA antibodies were positive in only 9.8% of the cases at the time of the study and none had a positive RF. The profile of autoantibodies was similar to other studies except for a lower incidence of anti-ENA antibodies. Sixty three percent of patients had lupus nephritis. The pattern of clinical presentations were noted to be more similar to those found among Chinese and Indian
SLE
populations than compared to the Caucasians. There was a significant association between anti-dsDNA antibody and lupus nephritis and between anti-ENA antibody and thrombocytopenia.

The etiology of
systemic lupus erythematosus
(
SLE
) is unknown but genetic factors seem to play a role in the disease pathogenesis. The tumor necrosis factor alpha (TNFa) gene, encoded at the TNF locus in the MHC class III region, is now known to be an important candidate gene in
SLE
, due to the proinflammatory activities of the TNFa. The objectives of this study were to examine the role of the TNFa polymorphism for the susceptibility of Malaysian Chinese
lupus
patients to
SLE
and to determine its association with organ involvement. The allelic frequencies of the TNFa polymorphic variant (TNF2) of seventy
lupus
patients were determined during follow-up at the Medical Clinic of the National University Hospital Malaysia by PCR-RFLP technique. Sixty-four females and 6 males with a mean age of 33+/-12 years were included. Clinical data were obtained from case records. Autoantibody levels were measured by ELISA. Fifty-nine ethnically-matched blood donors were used as controls. The allelic frequency of the TNF2 variant was found to be significantly increased in the patients compared to the controls (52.8% vs 33.8%).
SLE
patients with the polymorphic TNF2 variant were found to be at increased risk of central nervous system involvement (p = 0.004, RR = 2.59) and to have an increased frequency of anti-La antibodies (p = 0.03). In view of these findings we suggest that TNF2 variant is playing a role in conferring susceptibility to
SLE
and in the disease pathogenesis.

Neonatal lupus erythematosus is an uncommon passive autoimmune disease in which there is a transplacental passage of anti-Ro/SSA and/or anti-La/SSB maternal autoantibodies. Common clinical manifestations include cardiac disease, notably congenital heart block, cutaneous
lupus
lesions, hematologic disorders, and hepatobiliary disease. During the past decade, however, it has become clear that central nervous disease may also be a manifestation of neonatal
lupus
. We report a male neonate with the disease who had focal seizures in addition to cutaneous
lupus
, anemia, and thrombocytopenia. Brain ultrasound revealed normal ventricular size without a midline shift or intracranial or intraventricular hemorrhage. A brain CT showed generalized low density involving the periventricular and deep white matter. A sleep EEG revealed rare spikes axial to the right parietal lobe. The neonate had a high titer of antinuclear antibodies (1:640) with a speckled pattern, anti-Ro/SSA and anti-La/SSB antibodies, but no anti-dsDNA antibodies. He was given anti-convulsant drugs with dramatic improvement of his symptoms. One month later, a sleep EEG was normal, and he had no further seizures.

Antinuclear antibodies (ANA) frequently arise in the sera of children with connective tissue disease and is used in the diagnosis of these diseases. Therefore it is also important to know the prevalence of ANA in normal children. The main objective of the present study was to determine the prevalence of antinuclear antibody (ANA) in healthy children. Ninety-nine serum samples from a serum bank and 108 samples from patients who had attended elective surgery and whose blood had been withdrawn for other investigations, were tested for ANA by indirect immunofluorescence method using HEp-2 cells as substrate. Sera from 52 children with
SLE
were also tested during the same period. It was found that antinuclear antibodies were present in 32 (15%) of the 207 sera of healthy children at a dilution of 1:40 or higher. ANA were positive in 9% at a serum dilution of 1:40, in 3% at 1:80 and in 3% at 1:160. The patterns of immunofluorescence staining were as follows: homogeneous in 46.7%, speckled in 20%, and nucleolar in 10%. In
SLE
patients, ANA were positive in 91%; 13% at a serum dilution of 1:40, 7% at 1:80, 20% at 1:160, 15% at 1:320, 9% at 1:640, 20% at 1:1,280 and 9% at > or = 1:2,560. It was concluded that the prevalence of positive ANA using the HEp-2 cells as substrate was 15% in healthy children at dilutions of 1:40 or higher. Using the cutoff serum dilution of 1:40, the sensitivity of this test was 91%, the specificity was 85%, the positive predictive value was 57% and the negative predictive value was 97%.

There is considerable evidence that polymorphisms in the regulatory regions of cytokine genes are highly influenced by ethnicity. Polymorphisms in interleukin 1-beta (IL-1beta) and IL-1 receptor antagonist (IL-1Ra) genes, respectively encoding a potent inflammatory agent and an antagonist, which combines with IL-1 receptors competitively, have been associated with a number of diseases like
systemic lupus erythematosus
, rheumatoid arthritis, sepsis, kidney diseases, and cancer. In this study, we therefore evaluated the distribution of interleukin-1 gene cluster (IL-1beta promoter region, exon-5 and IL-1Ra) gene polymorphisms in 206 healthy north Indian subjects, using PCR-based restriction analysis. We also constructed various haplotypes and estimated the linkage disequilibrium (LD). We found that genotype and allelic frequencies for these cytokines were conspicuously different when compared among different ethnic populations. The haplotype 'T-E1-1' predominated (41.7%) while the least common was 'C-E2-2' (2%) in our population. Genetic linkage between three loci of IL-1 gene showed strong association among the variants in controls (D'=0.42, p<0.001). Our results suggest that the frequency and distribution of the polymorphisms in India are substantially different from other populations and ethnic groups. Thus they signify an impact of ethnicity and provide a basis for future epidemiological and clinical studies.

An examination of the prevalence and phenotype of immune disorders in different ethnic groups may provide important clues to the etiopathogenesis of these disorders. Whilst still conjectural the restricted and somewhat unique polymorphisms of the MHC (and other genetic loci involving host defences) of the Australian Aborigines may provide an explanation for their apparent heightened susceptibility to newly encountered infections and their resistance to many (auto) immune and allergic disorders. In comparison with non-Aboriginal Australians, Australian Aborigines have heightened frequencies of rheumatic fever,
systemic lupus erythematosus
, various infections and post-streptococcal glomerulonephritis. In contrast various autoimmune disorders (e.g. rheumatoid arthritis, multiple sclerosis, CREST, biliary cirrhosis, coeliac disease, pernicious anaemia, vitiligo), B27 related arthropathies, psoriasis, lymphoproliferative disorders and atopic disorders appear infrequent or absent. Similarly various autoantibodies occur with increased or diminished frequency. With continuing racial admixture, social deprivation and deleterious lifestyles of these people it is likely that further changes in both the frequencies and phenotype of these immune disorders will occur. It is only with a full understanding of the pathogenic mechanisms involved in these immune disorders that meaningful and clinical relevant interventions will be possible.
