Steroid-Sparing Agents for Difficult Nephrotic Syndrome

Monitoring has to cover growth, charting height and weight and adjusting diet if the child is faltering, immunisation status, since immunity is lower on immunosuppressants and needs support, and the eyes, since cataracts and raised intraocular pressure can develop and fundus changes can reflect hypertension. Blood pressure itself needs care to interpret correctly: parents are asked to record home readings at different times of day along with the child's position and activity, since white-coat hypertension can otherwise be mistaken for the real thing. Longer term, children with frequent relapses can also develop hair loss, hypothyroidism and visible skin changes, all of which need specific follow-up.

Yes, that is exactly right, and it is the better model in most cases: it costs the patient far less, and a local doctor who can actually follow the child up in person, combined with specialist input from India, including guidance on when to move from one drug to the next and what blood work to watch, generally serves the patient better than travel. Medicines can also be shipped through distributors once a clear treatment plan and prescription exist from both sides, since India's role as a manufacturing hub keeps costs down.

Malnutrition and nephrotic syndrome are clinically distinct. A malnourished child typically has a pot belly from reduced muscle rather than true fluid-filled swelling, no puffiness around the eyes, and serum albumin is rarely below 2.5. In nephrotic syndrome, parents will describe a clear pattern of oedema starting around the eyes, then spreading to the face, hands, legs, abdomen and genitals, along with breathing or walking difficulty from the fluid accumulation, and albumin drops well below that malnutrition threshold.

Albumin infusion alongside diuretics is reserved for children with resistant, severe oedema, generalised swelling causing respiratory or genital distress, or an albumin level around 1.5 or below. A child with just mild eyelid swelling from a relapse does not need diuretics: the relapse itself is treated first, typically with steroids and review every third day, and diuretics are added only if the swelling is not settling, partly because prolonged oedema is an excellent medium for secondary bacterial infection, including spontaneous bacterial peritonitis.

It follows the same mechanism as the rest of the oedema: low albumin causes fluid to shift into dependent spaces in the body, and the right lung is affected somewhat more often than the left. The underlying pathophysiology is hypoalbuminaemia driving fluid out of the vascular space into surrounding tissue, known as third spacing.

Levamisole, for children whose steroid requirement stays below 0.5 mg per kg. It is inexpensive with relatively few side effects, and Indian and African children in particular tend to respond well to it.

A 12-week course of cyclophosphamide is given, but it is not repeated because of the risk of gonadal toxicity, and it is avoided in children under four or five years old and in adolescents for the same reason.
