Selected risk factors for coronary heart disease in male scholars from the major South African population groups.
A number of risk factors for coronary heart disease (CHD) in 7 groups of South African male scholars aged between 15 and 20 years were surveyed. Selection of the groups was based on socioeconomic status and comprised urban and rural blacks, Indians of higher and lower socio-economic status, coloureds of higher and lower socioeconomic status, and middle-class whites. Both Indian groups, both coloured groups and the whites had a much greater prevalence and severity of CHD risk factors than the two black groups. This held for total cholesterol, low-density lipoprotein cholesterol (LDLC), high-density lipoprotein cholesterol (HDLC), the HDLC/LDLC ratio, apolipoprotein B, apolipoprotein A-I, insulin, fibrinogen and mass. One exception was lipoprotein a, levels of which were higher in both black groups. In general the CHD risk factor profile was worse in the higher socio-economic groups, and it also tended to be worse in urban than in rural blacks. These findings stress the need to reduce CHD risk factors in our developed populations and to prevent their emergence in our developing peoples.

Disseminated strongyloidiasis in a diabetic patient.
A case of disseminated strongyloidiasis in an Indian diabetic patient who was not receiving any immunosuppressive therapy, is reported. Strongyloides stercoralis was detected in peritoneal fluid, stools and blood. To our knowledge this represents the first such case to be reported in the English literature. The need for both clinicians and microbiology laboratories to be on the alert for this parasite in patients who are compromised either because of underlying disease or therapy with immunosuppressive drugs, is emphasised.

Serum lipoproteins and apolipoproteins in young normocholesterolaemic, non-diabetic Indian men with myocardial infarction.
Serum total cholesterol, triglycerides, high density lipoprotein cholesterol, low density lipoprotein cholesterol, apolipoprotein A-I and apolipoprotein B were evaluated as potential indicators of the risk of coronary artery disease in young (less than 46 years) normocholesterolaemic, non-diabetic men who had previously sustained a myocardial infarction (n = 50) and in healthy age and sex matched controls (n = 122) with a similar socioeconomic background. Significant differences were observed between patients and controls in the mean concentrations of serum total cholesterol, triglycerides, low density lipoprotein cholesterol, high density lipoprotein cholesterol and apolipoprotein B, as well as in the ratios of total cholesterol to high density lipoprotein cholesterol and apolipoprotein A-I to apolipoprotein B. No significant difference was demonstrated in the concentration of apolipoprotein A-I between the two groups. Stepwise discriminant analysis indicated that apolipoprotein B was the best discriminant between patients and controls. The percentage of exact classification was 74% in patients and 66% in controls. When the patients were compared to a subset of controls (n = 50) matched for age and total cholesterol, significant differences were demonstrated only in the mean concentrations of apolipoprotein B. Discriminant analysis confirmed that the best single discriminating variable was apolipoprotein B. The results therefore indicate that in young normocholesterolaemic, non-diabetic Indian men with myocardial infarction, apolipoprotein B is superior to other lipid parameters studied, as a marker for coronary artery disease.

Typhoid fever in the adult and paediatric Indian population of Durban.
The features of typhoid fever in Indian South Africans are described. In children the illness was usually uncomplicated. However, anaemia, thrombocytopenia and hypo-albuminaemia were found in both adults and children. The initial symptoms on presentation of diarrhoea and vomiting frequently led to a misdiagnosis of gastro-enteritis. The previous administration of antibiotics also resulted in failure to isolate Salmonella typhi in 41% of patients studied. Typhoid acquired in the microbiology laboratory and that seen in visitors returning from India and the Far East is emphasised. The S. typhi isolates were uniformly sensitive to all antibiotics tested. The disproportionately high number of Indians of south Indian ancestry presenting to the R. K. Khan Hospital needs to be investigated.

Hepatocellular carcinoma in South African Indians resident in Natal.
Hepatoma is a rare disease in Natal Indians. It occurs in male patients in the fifth decade. They have no history of alcohol intake. The main presenting feature is abdominal pain, weight loss and hepatomegaly. Blood tests reveal a raised alkaline phosphatase, hypoalbuminaemia, hypergammaglobulinaemia and markedly raised gamma glutamyl transferase. The tumour is a single large expanding mass in the right lobe. The patient usually presents in a late stage of the illness and shows a progressive downhill course. Hepatitis B virus infection is emerging as the likeliest carcinogen.

Autoantibodies to thyroxin and triiodothyronine.
Two clinically euthyroid patients with multinodular goiter were found to have high "free" thyroxin (Amerlex-M, Amersham and Coat-a-Count, DPC) and triiodothyronine (Amerlex-M) concentrations (FT4 and FT3, respectively). The presence of antibodies to T4 and T3 was confirmed by the finding that polyethylene glycol precipitated a far greater proportion of radioactivity when radiolabeled FT4 or FT3 analog (Amerlex-M) was incubated with serum from these patients than was true for normal subjects. With this method we could not demonstrate antibodies to thyroid hormones in 116 healthy volunteers. Of 101 hyperthyroid patients tested, one had antibodies to T4 but none had antibodies to T3. One patient had antibodies to T4, and one to T3, of 36 hypothyroid patients tested. All patients with thyroid hormone antibodies also demonstrated antithyroglobulin antibodies (measured immunoradiometrically). Evidently, the presence of thyroid hormone antibodies should be suspected when results of thyroid-function tests are discordant with the clinical state, and we suggest that measurement of thyrotropin by an assay with improved detection limits will aid in correctly determining thyroid status.

The occurrence of Z-type diabetes (tropical pancreatic diabetes) in the South African Indian.
The presentation of diabetes in the young South African Indian is atypical in that insulin-dependent diabetes mellitus is rare, while non-insulin-dependent diabetes mellitus is common. In addition, youthful onset of tropical diabetic syndrome (J-type diabetes) is extremely rare. To date there appear to be no reports on a further tropical malnutrition diabetic syndrome associated with pancreatic fibrosis and calcification (Z-type diabetes). Four Indian patients with features consistent with the diagnosis of Z-type diabetes are described. All were asthenic, came from a poor socio-economic background and developed insulin-requiring diabetes in their youth; 3 of the 4 patients had pancreatic calcification.

An assessment of posterior pituitary function in patients with Sheehan's syndrome.
Antidiuretic hormone (ADH) function was assessed in a group of 16 patients with Sheehan's syndrome and 17 controls. All patients were on adequate cortisone and thyroxine replacement therapy before testing. During the dehydration test the patients revealed an impairment of ADH function. The maximum urine osmolalities and the urine-plasma osmolality ratios were significantly lower in the patients with Sheehan's syndrome compared to controls (maximum urine osmolalities 633 +/- 38 (SEM) and 873 +/- 29 (SEM) mOsm/kg, respectively, P less than 0.001; urine-plasma osmolality ratios 2.15 +/- 0.14 (SEM) and 3.01 +/- 0.10 (SEM), respectively, P less than 0.001). Plasma osmolalities were significantly higher in the patients (296.1 +/- 1.2 (SEM) and 290 +/- 0.9 (SEM), respectively, P less than 0.001). The patients took a longer period to achieve these maximum urine osmolalities. Three of the patients with Sheehan's syndrome were diagnosed as having diabetes insipidus since their maximum urine osmolalities were below 600 mOsm/kg and following desmopressin all three had an increment in urine osmolality which exceeded 9%. In addition these three patients had a maximum urine-plasma osmolality ratio below 1.9. Thus, it appears the patients with Sheehan's syndrome have an impairment of ADH function which manifests in some as diabetes insipidus.

Stress hyperglycaemia is a predictor of abnormal glucose tolerance in Indian patients with acute myocardial infarction.
66 non-diabetic Indian patients with acute myocardial infarction were assessed prospectively for the presence of hyperglycaemia and the value of this admission hyperglycaemia and glycosylated haemoglobin (HbA1) levels in reflecting the glucose tolerance status of the patients was studied. Hyperglycaemia, defined as admission plasma glucose greater than or equal to 8 mmol/l was detected in 49% of the patients, whilst raised HbA1 values were seen in 11%. The admission plasma glucose (APG) correlated significantly with both the HbA1 levels and with the 2 hour glucose value in the oral glucose tolerance test (p less than 0.001). An oral glucose tolerance test performed 3 months after the acute episode revealed that 35 patients (53%) had abnormal glucose tolerance according to WHO criteria. Of the patients with initial hyperglycaemia, 75% had abnormal glucose tolerance tests, whilst 32% of patients with normal APG had abnormal glucose tolerance. Abnormal glucose tolerance was also detected in all patients with raised HbA1 values (greater than 8.9%) and in 48% of patients with normal levels. The sensitivity and specificity of APG greater than or equal to 8 mmol/l for abnormal glucose tolerance was 68.6% and 74.2% respectively and that of raised HbA1 values were 20% and 100%. Hence an APG greater than or equal to 8 mmol/l in patients with myocardial infarction is more likely to indicate the presence of unrecognized abnormal glucose tolerance rather than stress. HbA1 measurements do not appear to offer any further advantage in the assessment of hyperglycaemia following myocardial infarction.

Insulin secretion in Indian patients with impaired glucose tolerance.
The insulin response to a 75 g oral glucose load was studied in 26 indian patients with impaired glucose tolerance (IGT) and 26 controls matched for age, sex and weight. There were no significant differences between the mean insulin responses and incremental insulin areas between the patients with IGT and controls. However, when the patients were divided into obese and non-obese subgroups and their mean insulin levels compared, the obese patients with IGT had significantly higher insulin levels at 120 minutes than the obese controls.

Antibodies to the thyroid gland and to the thyrotrophin receptor in African and Indian thyrotoxic patients.
Sixty two thyrotoxic patients, 34 African and 28 Indian, were studied in order to assess the prevalence of thyroid antibodies and TSH binding inhibitory activity (TBI): 45 had Graves' disease and 17 had toxic nodular goitres. Microsomal and thyroglobulin antibodies were positive more often in Indian than in African patients with Graves' disease (microsomal 52% vs 37.4%, P less than 0.05; thyroglobulin 38.1% vs 4.2%, P less than 0.001). Patients with toxic nodular goitres had a lower prevalence of positive microsomal antibodies (P less than 0.01), but not of thyroglobulin antibodies (P = 0.1) when compared with patients with Graves' disease. TBI activity measured by a radioreceptor assay was positive in 43 of the 45 (95%) patients with Graves' disease and only 1 of the 17 patients (5.9%) with toxic nodular goitre. It thus appears that TBI activity is a sensitive marker in the diagnosis of Graves' disease and that there is a lower prevalence of thyroglobulin and microsomal antibodies in African patients compared with Indian patients.

Prolactin secretion in Sheehan's syndrome. Responses to thyrotropin-releasing hormone and metoclopramide.
The prolactin response to thyrotropin-releasing hormone (TRH) and metoclopramide was studied in 16 patients with Sheehan's syndrome and 16 matched controls in the follicular phase. Metoclopramide resulted in a greater prolactin response than TRH did in the controls. However, both stimuli failed to evoke any appreciable prolactin response in the patients with Sheehan's syndrome. Since metoclopramide is generally free of side effects and far cheaper than TRH, we recommend the prolactin response to metoclopramide as the preferred screening test in the diagnosis of Sheehan's syndrome.

The spectrum of non-insulin-dependent diabetes in the young in a migrant Indian population.
The familial aggregation and degree of adiposity of 108 Indian patients with non-insulin-dependent diabetes in the young was studied. All patients had onset of diabetes under 30 yr and the female to male ratio was 5:1. Obesity as defined was present in 52 patients (48.2%). A positive family history of diabetes was present in 90 patients (83.3%). Two distinct subtypes emerged in the patients with a positive family history; the offspring of conjugal diabetic parents (29%) and maturity onset diabetes of the young (MODY) with 3-generation transmission (13%). In conclusion, the syndrome of NIDDY in Indians comprises at least 3 subtypes: offspring of conjugal diabetic parents, MODY and patients without a family history (sporadic type).

The prevalence of diabetes mellitus in a large group of South African Indians.
The prevalences of diabetes mellitus and impaired glucose tolerance (IGT) among 866 Indians living in the Chatsworth area of Durban were determined. The study group was selected by cluster sampling and the participants underwent a modified glucose tolerance test (GTT) (determination of fasting and 2-hour plasma glucose levels after a 75 g glucose load). On the basis of the revised World Health Organization criteria the overall prevalence of diabetes mellitus was 11% and of IGT 5,8%. Of the 368 men, 7,6% were found to have diabetes mellitus and 7,1% IGT; the prevalence of diabetes mellitus was much greater among women (13,5%), while there was less IGT (4,8%). Subjects with diabetes mellitus were significantly older (mean 50,7 years) than those with a normal GTT (mean 30,9 years), but of similar age distribution compared with the IGT group (mean 46 years). Subjects with a normal GTT had a significantly lower mean body mass index (22,1 +/- 2,8) compared with diabetic subjects (26,1 +/- 5,2) or the IGT group (25,8 +/- 6,6). Obesity was commonly associated with both diabetes mellitus and IGT, particularly among women.
