Quartan malarial infection causes an immune complex nephritis in some individuals, which, once established, is sustained by mechanisms not yet fully explained, but which probably involve autoimmune processes. The presenting clinical and biochemical findings of the quartan malarial nephrotic syndrome are similar to those classically described for the nephrotic syndrome in childhood, but the renal pathology seen on light, electron, and immunofluorescent microscopy show striking differences and distinctive features. The disease tends to pursue a chronic course and in most patients is nonresponsive to treatment with antimalarial drugs, prednisolone, and immunosuppresive drugs. The overall prognosis is poor, with most patients developing hypertension and evidence of renal failure within 3 to 5 years of onset.

In 51 patients with type 1 and 9 patients with type 2 membranoproliferative glomerulonephritis, we found a male predominance in both types, a wide age range but with younger patients having predominantly type 2 disease, and clinical presentations that varied and included the nephrotic syndrome, an abnormal urinalysis only, acute nephritis, and recurrent hematuria. Hypertension and impaired renal function at the time of first evaluation, which were present in more than one-third of the patients, presaged a poor prognosis; in most of these patients end-stage renal failure or worsening of renal function occurred. Acute nephritis at onset was also related to a deteriorating course and was especially frequent in patients with type 2 membranoproliferative glomerulonephritis. Retrospective analysis of treatment regimens, in which patients were given an average of 1 year of therapy with prednisone alone or combined with cytotoxic agents, showed no effect in patients who had progressive forms of the glomerulopathy.

Sixty six patients with lupus nephropathy with hypertonic syndrome are examined. In patients with latent (inactive) lupus glomerulonephritis hypertonic syndrome developed 3--8 months after the initiation of the corticosteroid treatment, advancing with fluctuations, in some of the patients the arterial pressure being normalized after the discontinuation of that treatment. In patients with chronic active lupus glomerulonephritis without nephrotic syndrome, the hypertension develops before the initiation of the corticosteroid treatment, fluctuating at the beginning, and gradually assumes a stable character 3--5 months after the beginning of such treatment, sometimes with a malignant course and rapid development of renal insufficiency. The hypertonic syndrome advances most severely and malignantly in chronic lupus glomerulonephritis with nephrotic syndrome and is resistant to the active antihypertensive treatment. In 18, out of 25, such patients, the hypertonic syndrome is manifested in parallel with nephropathy before the inclusion of the cortocosteroid treatment. The grave and malignant course of the hypertonic syndrome is associated with the peculiarities of the clinical form and histomorphological type of that lupus nephropathy. In the patients with nephrosclerosis, the hypertonic syndrome is with a gradually progressing evolution, in parallel with the progress of the renal insufficiency.

In a retrospective survey of renal amyloidosis in a large general hospital, only 7 cases were found. Patients generally presented with nephrotic syndrome and symptoms of fluid overload; hypertension on presentation was unusual. Renal failure was present in 5 out of 7 patients, and uraemia in 3. The disease was secondary in 5 patients and primary in 2, and the prognosis was uniformly bad.

A study of 3451 cholesterol determinations in different diseases was carried out. The mean cholesterol levels for male and female adults and children with different diseases were compared with values for their healthy counterparts. Sickle cell anemia, leukemia, liver cirrhosis, hepatosplenomegaly, tuberculosis, and diabetic, nutritional, ataxic, and tropical neuropathies in male and female adults were associated with reduced cholesterol level while in children malnutrition and anemia were the main causes of low cholesterol levels. Obesity and hypertension caused an elevated level but the mean values were within the range for adult Nigerians in the high income group. Only nephrotic syndrome in both adult and children was associated with a markedly increased cholesterol level in Nigerians of low income status.

A patient with a single functioning kidney presented with the nephrotic syndrome. On the basis of highly selective proteinuria, a diagnosis was made of lipoid nephrosis. Steroid therapy over a 2-year period did not control the disease. The patient eventually developed end-stage renal failure and malignant hypertension. Nephrectomy was performed to control the hypertension. Histological examination showed congenital dysplasia in one kidney and sclerosing glomerulonephritis, malignant nephrosclerosis, as well as dysplastic changes in the other.

The study involved 298 cases of chronic glomerulonephritis (GN) in adults. The results of renal biopsy were used to classify the patients into four groups: Membranous GN, 81 cases; focal glomerulo sclerosis, 80 cases; Membrano-proliferative GN, 62 cases; GN with mesangial deposits of IgA, 75 cases. The patients were observed over a period ranging from 1 month to 36 years. The average period of surveillance for each category was between 4 and 6 years. The course in each histological type was assessed on the basis of actuarial tates of renal death, of moderate renal insufficiency (plasma creatinine greater than 1.5 mg%( and of hypertension. Renal survival at 10 years was was arounds 90% for membranous GN. 85% for GN with mesangial deposits of IgA, 70% for focal glomerulo sclerosis and 50% for membrano-proliferative GN. The prognosis should be based upon a combination of histological and clinical findings. Severity of prolonged nephrotic syndrome, regardless of the histological type of the nephropathy, is worthy of emphasis. In the group fo focal glomerulo sclerosis, prognosis differs greatly in relation to the presence or absence of a nephrotic syndrome. Complete remission may be seen in the group of focal glomerulo sclerosis, and in membrano-proliferative GN despite the persistence or worsening of histological lesions seen on repeated biopsies.

More than half of the patients with glomerulonephritis, nephrotic syndrome and renovascular hypertension showed obviously abnormal profiles of serum lipoproteins (Lps). The abnormal profiles returned to normal or near-normal when the disease was ameliorated or corrected surgically. A unique Lp profile (broad midband pattern, BMP) was observed in approximately 89% of uremic patients on hemodialysis therapy. The results of the current investigations indicated that the BMP could probably be formed by the accumulation of catabolic remnants of VLDL.

Acute renal failure, severe hypertension, and some complications of the nephrotic syndrome and chronic renal failure are the renal emergencies most frequently seen in the pediatric age group. Diagnosis of acute renal failure is based mainly upon U/P ratios of osmolality and urea as well as a negative mannitol test. Conservative medical management is useful in uncomplicated cases, whereas dialytic procedures are more effective in severe or complicated cases. The most frequent reversible complications in chronic renal failure are infections, extracellular volume changes, electrolyte imbalance and cardiovascular alterations. Intercurrent infection and vein thromboses are the most frequent complication in minimal change nephrotic syndrome and they may be a cause of death. Early diagnosis and adequate treatment are mandatory in these complications.

In dealing with asymptomatic hematuria or proteinuria in the pediatric population, the physician should begin with an organized, logical sequence of diagnostic steps, including careful review of the history, physical findings, and laboratory data. If serious glomerular disease is suspected (eg, presentation atypical of acute poststreptococcal glomerulonephritis, nephrotic syndrome beyond the usual age for idiopathic nephrotic syndrome of childhood, renal insufficiency, severe hypertension), biopsy is probably inevitable, and early referral to a nephrologist is urged.
