The triad of severe pre-eclampsia is often described as a combination of hypertension, oedema and proteinuria. Hypertension alone arising in the second half of pregnancy however is not associated with any greater perinatal mortality or low birthweight than normotensive primigravidae and it is probable that this hypertension may be either physiological or a manifestation of essential hypertension or, in some cases, a mild form of pre-eclampsia. Oedema also does not necessarily signify abnormality. High weight gain, fluid retention or oedema is associated with a lower incidence of small babies, but with a higher incidence of pre-eclampsia. Considerable amounts of water retention can occur in normal pregnancy, either measured as an increase during pregnancy, or as a fall after delivery. The diuretics cyclopenthiazide, spironolactone and clopamide given prophylactically to high weight gain primigravidae did not prevent the onset of proteinuric pre-eclampsia, but caused the babies to be lighter in weight than those of controls. Sodium potassium and water content of leucocytes from primigravidae with proteinuric pre-eclampsia is the same as in mild pre-eclampsia and normal pregnancy. Although salt and water retention are common features of pre-eclampsia, they do not cause the condition and are not an essential part of it.

Polyneuropathy is a prevalent and disabling disorder. Despite extensive evaluation, the cause often remains unknown. Factors that predispose for the development of polyneuropathy need to be identified. We investigated the effect of anthropometric and metabolic factors on peripheral nerve function in 908 participants of the population-based Rotterdam Study without any symptoms or signs of polyneuropathy. Participants underwent nerve conduction studies of the sural and peroneal nerve. Data on age, height, weight, waist circumference, diabetes, lipid levels, hypertension, and kidney function were collected. Regression analyses were used to investigate determinants of nerve action potential amplitudes. The frequency of abnormal sural sensory nerve action potential (SNAP) amplitudes increased with age from 1% under 60 years to 23% over 80 years. Similarly, the frequency of abnormal peroneal nerve compound motor action potential (CMAP) amplitudes increased from 4% to 13%. High weight and body mass index were independently associated with reduced sural SNAP amplitudes and peroneal CMAP amplitudes. Participants with hypertension and kidney dysfunction were more likely to have abnormal sural SNAP amplitudes. Older age, high weight, hypertension, and moderate kidney dysfunction might thus lead to peripheral nerve dysfunction in persons yet without symptoms or signs of polyneuropathy.
