Abstract
The prevalence of lupus anticoagulant (LAC) and its relation with reported clinical associations has been determined in 55 patients with systemic lupus erythematosus (SLE) from northern India who were studied prospectively. Kaolin clotting time was used to screen for LAC, which was detected in seven (13%) of the patients. Significant associations were found between LAC and thrombotic events, onset of disease at an early age, and disease of shorter duration. No statistically significant association could be found between LAC and recurrent abortions, pulmonary hypertension, thrombocytopenia, and neurological manifestations. It is concluded that LAC is a useful marker for a subset of patients with SLE at risk of thromboembolic events.

Abstract
Estimation of antithrombin III, alpha 2 macroglobulin and alpha 1 antitrypsin in patients with stable and unstable angina and acute myocardial infarction (15 cases each) were carried out. Twenty age, sex and weight matched healthy subjects were included as controls. Mean platelet factor 4(PF4) levels measured in 10 cases of each subgroup were significantly elevated in myocardial infarction (MI) (48.4 +/- 15.16 ng/ml) and III unstable angina patients (44.7 +/- 15.9 ng/ml) as compared to controls (25.42 +/- 12.47 ng/ml; P less than 0.01). Mean antithrombin III (AT III) levels were markedly reduced in all patients with MI (39.65 +/- 12.8% of normal pooled plasma) and unstable angina (37.9 +/- 16.6% of normal pooled plasma) and in 9 patients with stable angina. Alpha I antitrypsin and alpha 2 macroglobulin levels in these cases showed no significant difference compared to normals. Reduced AT III in coronary artery disease suggests a prethrombotic tendency in these patients. Raised PF4 levels in acute phase of the disease suggests heightened platelet activation.

Abstract
Red-cell enzymes and reduced glutathione (GSH) were assayed on cord blood in 307 Indian neonates. On follow-up, 20 of them developed pathologic jaundice. Of these, six had red-cell enzyme/GSH deficiency, seven had associated non-enzymatic causes of jaundice, and in the remaining seven the cause could not be diagnosed. In 41 other neonates, there was enzyme/GSH deficiency without pathologic jaundice. The degree of enzyme deficiency had no relation with jaundice. Red-cell enzyme/GSH deficiency state in neonates was associated with pathologic jaundice more frequently (six of 47; 12.8%) than in the absence of such deficiency (14 of 260; 5.4%). None of the jaundiced patients had very high levels of bilirubin nor needed exchange blood transfusion. There was no reduction in haemoglobin level in the enzyme/GSH deficient group with jaundice in comparison with non-deficient jaundiced neonates or normal subjects. The incidence of red-cell enzyme/GSH deficiency appears to be high in Indian neonates; however, the majority of them do not precipitate pathologic jaundice.

Abstract
A simple and inexpensive micromethod based on methaemoglobin reduction technique (MRT) for screening of glucose-6 phosphate dehydrogenase deficiency has been studied using reagent-impregnated curvettes incubated in a makeshift waterbath. The cuvettes shelf life has been tested upto nine months. As the test can be done with finger prick blood, it promises to be more acceptable in the field. The sensitivity of this is similar to classical MRT.

Abstract
Coagulation profile was studied in 55 patients of systemic lupus erythematosus (SLE). Abnormal kaolin clotting time (KCT) was observed in fewer patients (12.9%) as compared to abnormal Russel's viper venom time (RVVT, 20.4%) or activated partial thromboplastin time (APTT, 32.7%). Prolonged prothrombin time (PT), observed in 7.3 per cent patients was not found to be a sensitive test for lupus anticoagulant (LAC). The correction of RVVT and KCT on addition of inosithin suggested a deficiency of platelet lipid factor in these patients. The initial value of uncorrected KCT in patient's plasma did not correlate with the amount of inosithin required for neutralisation. Occurrence of thromboembolic events was significantly associated with prolonged KCT. No other clinical feature showed significant association with any coagulation abnormality.

Abstract
In 10 patients of type I diabetes who were free from clinically apparent vascular disease, platelet functions were studied prior to control, and 10 days and 3 months after strict metabolic control. Platelet hyperactivity, seen as significant shortening of latent period and increase in rate and degree of aggregation, present in patients in the initial uncontrolled state, but absent at the subsequent two periods did not correlate with glycosylation of haemoglobin. Thus control of diabetes mellitus, capable of reversing platelet hyperactivity, is reflected by blood sugar levels, and not by the glycosylation status of haemoglobin.

Abstract
Coagulation studies were carried out in 14 children with haemolytic uraemic syndrome that followed acute dysentery. Stool cultures showed Shigella dysenteriae in 3 cases and were sterile in the remainder. Prolongation of the prothrombin time, activated partial thromboplastin time and thrombin time and raised levels of fibrinogen degradation products were found in 12 cases, indicating the presence of disseminated intravascular coagulation. Renal histologic examination showed cortical necrosis in 7 cases, which was extensive in 5 and patchy in 2. Disseminated intravascular coagulation may have a role in the pathogenesis of haemolytic uraemic syndrome associated with acute dysentery.

Abstract
The efficacy of serum folate (SF), red blood cell folate (RCF), and serum B12 in diagnosing folate and B12 deficiency, and the effect of iron overload on hemoglobin, were studied in 157 cases of homozygous beta thalassemia (HBT). The patients had lower SF compared with normal subjects (NS) (P less than 0.001) and higher RCF than their parents (P less than 0.001) and NS (P less than 0.001). Forty percent of patients had both low SF (less than 3 ng/mL) and high RCF (greater than 600 ng/mL). Homozygous beta thalassemia patients are known to have folate deficiency. Yet, both folate and B12 deficiency status were similar in the authors' patients and NS. These deficiencies apparently were less in patients compared with their parents, who shared the same nutritional milieu (P less than 0.001). Mean hemoglobin in patients with iron overload (transferrin saturation, TS greater than 50%) was lower than in those without (P less than 0.005). The following is concluded: (1) diagnosis of folate and B12 deficiency based on SF, RCF and serum B12 is vitiated in HBT and needs a therapeutic trial; (2) iron overload of a magnitude indicated by TS greater than 50% can aggravate anemia in HBT.

Abstract
Serum ferritin, serum iron, and unsaturated iron binding capacity were studied in 64 patients with beta homozygous thalassemia (BHT), 120 patients with beta heterozygous thalassemia, and 46 normal subjects. Incidence of iron overload seen in 32 BHT cases was similar in untransfused and transfused cases. Among heterozygotes, iron stores were depleted in 24 (20%), mostly females (70.8%). Only male heterozygotes but not normals were iron deficient. In 18 (75%) heterozygotes with depleted iron stores, transferrin saturation (TS) was normal. It was also normal in 8 (25%) BHT patients and 5 (100%) heterozygotes with iron overload. In 13 (35.1%) BHT patients, it was raised in the absence of iron overload. It was concluded that iron deficiency in heterozygotes is of greater magnitude, especially in females, than hitherto known in India. Transferrin saturation is not a good indicator of either iron depletion or overload. Iron supplementation is recommended in heterozygous beta thalassemia in infants, children, and expectant mothers in geographic areas with high incidence of iron deficiency.
