Prospectively gathered data from eight geographically defined areas in south-east Asia included serial measures of blood pressure, proteinuria and oedema during pregnancy. A total of 15,476 pregnancies were included. Both antenatal oedema and proteinuria were markers of increased risk of antenatal diastolic hypertension, proteinuric pre-eclampsia and eclampsia. However they identified fetuses at high risk of low birthweight and perinatal mortality only in areas where the incidence of hypertension was low. As a screening strategy to identify women who are at increased risk of antenatal diastolic hypertension, of proteinuric pre-eclampsia and of eclampsia, the most efficient strategy is probably to use the presence of oedema and/or proteinuria. The sensitivity of using this method for identifying women with proteinuric pre-eclampsia is high, but for identifying eclampsia it is still relatively low. Where resources are available there is probably no substitute for using a sphygmomanometer and measuring blood pressure.

The incidence of acute renal failure, hypertension and electrolyte disorders in 64 bone marrow transplant recipients randomized to receive either cyclosporin or cyclophosphamide was investigated. Sixty-four per cent of patients developed acute renal failure, 75 per cent hypertension, and 88 per cent significant hypomagnesemia. The incidence of diastolic hypertension and hypomagnesemia was greater in the patents treated with cyclosporin. Hypomagnesemia was due to magnesium wasting by the kidney. Both groups received similar cumulative doses of aminoglycoside antibiotics. Significant proteinuria developed in all but one patient and nephrotic-range proteinuria was noted in 21 per cent. The cause of the proteinuria is unclear; no obvious morphologic changes were seen at autopsy in patients who exhibited nephrotic-range proteinuria. The abnormalities of renal function were shown to be transient in patients who were observed for periods ranging from one to three years. It is concluded that hypertension, renal failure and hypomagnesemia are common in the setting of bone marrow transplantation. Whereas cyclosporin probably aggravates the severity of these disorders, it is likely that other factors (e.g., aminoglycoside antibiotics) play a major role as shown by the high incidence of renal and electrolyte disorders in patients treated with cyclophosphamide alone.

The epidemiology, pathogenesis, significance and management of hypertension in diabetic subjects are discussed. In Type 1 diabetes the presence of diastolic hypertension is closely related to the presence of diabetic nephropathy, from the stage of persistent proteinuria onwards. There may also be some elevation of systolic pressure. The apparent increased prevalence of hypertension in Type 2 diabetes is largely explicable, directly or indirectly, by obesity but there may be an excess of systolic hypertension among elderly patients. Hypertension in the diabetic population is associated with an increased incidence of both microvascular and macrovascular complications, but whether the high blood pressure is causal is not clear. The possible roles of sodium and insulin, the renin-angiotensin system, catecholamines and physical factors are explored. All current antihypertensive agents have additional limitations and disadvantages when used in diabetic patients: diuretics and beta-blockers are probably the initial drugs of choice. Only in the case of diabetic nephropathy is there yet reasonable evidence of antihypertensive treatment reducing the rate of progression of the disease.

The clinical course of 40 patients with significant quantities of mixed cryoglobulins, but without lymphoproliferative, collagen-vascular or chronic infectious diseases, is presented. These cases comprise 51.3 percent of all mixed and 31.7 percent of all types of cryoglobulins evaluated by us over the period 1960--1978. A characteristic clinical syndrome, consisting of recurrent palpable purpura (100 percent), polyarthralgias (72.5 percent) and renal disease (55 percent), was seen. Biopsy specimens of skin lesions showed cutaneous vasculitis, and half had immune reactants in vessel walls. Seventy percent of patients had evidence of hepatic dysfunction, often subclinical, and more than 60 percent of those tested had serologic evidence of prior infection with hepatitis B virus. Hepatic lesions ranged from minimal triaditis to chronic active hepatitis and/or cirrhosis. All 22 patients in whom clinical renal disease developed had significant proteinuria; 63.6 percent had diastolic hypertension, 77.3 percent edema, 45.5 percent renal failure and 22.7 percent were nephrotic. Glomerular disease associated with deposition of immunoglobulin G, immunoglobulin M and complement, often with coexistent renal arteritis, was confirmed pathologically in 15 cases. All cryoglobulins had rheumatoid factor activity and consisted of IgM and polyclonal IgG; five also contained IgA. Thirteen had a monoclonal IgM kappa component. Serum protein electrophoresis was unremarkable or showed diffuse hyperglobulinemia. Striking depression of early complement components was noted but did not correlate well with the cryoprotein concentration, renal involvement or clinical course. Follow-up for periods up to 21 years from onset of symptoms revealed that renal involvement has a deleterious effect on prognosis. Postmorten examinations of nine patients demonstrated widespread vasculitis in addition to renal involvement. Preterminal infection was found in eight.

Clinical decisions and controlled studies in regard to hypertension have long emphasized the casual diastolic blood pressure (DBP). The influence of superimposition of high systolic blood pressure (SBP) on the target organ damage has been less studied. To assess the role of isolated diastolic hypertension without interference of superimposition of systolic hypertension, 171 subjects with normal blood pressure, isolated diastolic hypertension (SBP < 140 and DBP > or = 90 mmHg) isolated systolic hypertension (SBP > or = 140 and DBP < 90 mmHg) or combined hypertension (SBP > or = 140 and DBP > or = 90 mmHg) determined by mean 24-h ambulatory blood pressure were compared in relation to target organ damage including ECG abnormality related to hypertension, cardiac enlargement by chest X-ray, proteinuria and retinopathy. The incidence of target organ damage was lower in subjects with normal BP than in the other three groups. The incidence of target organ damage was almost significantly higher in patients with isolated systolic hypertension than in those with isolated diastolic hypertension. No significant difference in the incidence of complications existed between patients with isolated systolic and combined hypertension. These findings demonstrate that the severity of hypertensive complications is more closely related to mean ambulatory SBP than mean ambulatory DBP. The level of systolic BP is important for predicting the severity of target organ damage in patients with high diastolic BP, because there is a significant difference in the incidence of target organ damage between isolated diastolic hypertension and combined hypertension.

From the follow-up examination of 1329 out of 4420 type 2 (non-insulin-dependent) diabetes followed for 17 years, the incidence of micro and macrovascular complications (proteinuria and nephropathy, symptoms of leg vascular disease, ischemic heart disease, and cerebrovascular events, was estimated and related to the levels of baseline-risk variables using logistic regression. For new cases of proteinuria and heavy proteinuria, hyperglycemia was the common predictor (alongside diastolic hypertension, smoking and overweight); hyperglycemia and glycosuria were among significant predictors of leg vascular disease (with duration of diabetes, smoking, male sex, diastolic hypertension, and proteinuria). On the other hand, systolic hypertension and male sex prevailed among factors predicting both ischemic heart disease (with high cholesterol and overweight), and stroke. The data confirm the higher involvement of diabetic milieu in micro than macrovascular incidents, with diabetic foot disease placed in between.

The goal of treatment of hypertension in older persons is to lower the blood pressure to <140/90 mm Hg. Older persons with diastolic hypertension should have their diastolic blood pressure lowered to 80 to 85 mm Hg. The blood pressure should be lowered to 130/85 mm Hg in persons with diabetes mellitus or renal insufficiency and to 125/75 mm Hg in persons with proteinuria of 1 gram per 24 hours. Diuretics or beta blockers should be used as initial drugs in the treatment of hypertension. The choice of antihypertensive drug in older persons with associated medical conditions depends on the associated medical conditions.

A survey was conducted in asymptomatic aged individuals (> or = 60 years) in The National Capital Territory of Delhi for the prevalence of major health problems like hypertension, diabetes mellitus and respiratory diseases. A total of 200 individuals (100 males and 100 females) were studied over a period of three months in 1998-99. Hypertension was defined as BP > or = 140/90 mmHg (JNC VI criteria), while diabetes mellitus was diagnosed if fasting whole blood sugar was 120 mg/dl or more (WHO criteria). Diagnosis of other health problems was based on relevant history and physical examination. Prevalence of hypertension in the study group was 32.5 per cent (more in males). Of these 18 per cent and 4.2 per cent had isolated systolic and diastolic hypertension, respectively. Prevalence of diabetes mellitus in the same population was 13.0 per cent. Both diseases were more prevalent in urban population. A high prevalence of respiratory disorders was observed (pulmonary tuberculosis 16 per cent, COPD 10 per cent, asthma 4.5 per cent). Cataract was present in 7.5 per cent while 1.5 per cent had symptoms of urinary tract infection. History of Jaundice was present in 3.5 per cent. Three per cent each had a history suggestive of IHD and TIA, respectively. Proteinuria and glycosuria was seen in 22.2 and 7.6 percent, respectively. A large percentage of the study group (34.4 per cent) had asymptomatic ECG abnormalities.

Two hundred eighty patients underwent renal biopsy during the period of 1995-1999 in five nephrological centers of Lithuania. All renal biopsies materials were examined in the State Center of Pathology. In 20 patients (7.1%) membranous nephropathy was found. The main clinical presentation at the moment of renal biopsy were nephrotic syndrome (55%) and arterial hypertension (55%). Glomerulosclerosis was found in 30% of patients, interstitial fibrosis--in 40% of patients. The results of analysis showed multiple risk factors for renal failure progression: initial renal failure (p=0.000), systolic and diastolic hypertension (p=0.009 and p=0.009), proteinuria (=1 g/l, =3 g/l) (p=0.026). Membranous nephropathy was found to have a relatively good long-term prognosis - the renal survival rate in 5 years was 84.2%. Kaplan-Meier survival analysis showed that initial renal failure was risk factor (logrank p=0.018, Breslov p=0.032) associated with development of end-stage renal disease in 5 years.

An Asian multiparous woman weighing 47 kg, who suffered from a rare myopathy, congenital fibre type disproportion, was given morphine 10 mg intramuscularly for labour analgesia. After delivery, she had diastolic hypertension and proteinuria and was prescribed magnesium sulphate. Some hours later she became unresponsive with little respiratory effort. Blood gas analysis revealed a respiratory acidosis. Naloxone administration reversed the symptoms. Further doses were required as the respiratory depression recurred. Opioid-related narcosis is the most likely diagnosis in this case. Other possible differential diagnoses were magnesium overdose or a post-ictal state. The presence of a myopathy could render this patient susceptible to the respiratory effects of opioids. Other explanations for an exaggerated and delayed response to opioids include co-administration of other respiratory depressant drugs such as magnesium sulphate, co-morbidity such as renal impairment and genetic variability in the metabolism of morphine. Robust guidelines and highlighting patients with risk factors are required to prevent this complication from recurring.
