Henoch-Schonlein syndrome in northern Indian children.

In order to evaluate clinical features and renal pathological findings of Henoch-Schonlein syndrome (HSS) in northern Indian Children, we studied 47 such cases. The mean age at onset was 8.5 yr; sex ratio (M:F) 2.6:1. The clinical features were purpuric rash (96%), abdominal pain (64%), Henoch-Schonlein nephritis (51%) and arthralgias (47%). Patients younger than 6 yr also showed urticarial rash or edema of scalp and extremities. Henoch-Schonlein nephritis (HSN) and abdominal symptoms were more common in older cases. The manifestations of HSN were asymptomatic hematuria and/or proteinuria (n = 15), acute nephritic syndrome (n = 6), and nephrotic syndrome (n = 3). The severity of clinical manifestations correlated with the renal pathologic findings. On follow up, 29% cases showed renal impairment. The prognosis was poor in patients with the acute nephritic or nephrotic syndrome and crescents in more than 50% glomeruli. Combination of clinical data and renal biopsy findings are important in assessing the long-term outcome in cases with HSN.

Nephronophthisis with bronchiectasis.

A boy with nephronophthisis and bronchiectasis, a previously unrecognised association is described. Electron-microscopic examination of a renal biopsy from an asymptomatic sibling revealed marked thickening and lamination of the tubular basement membranes.

Cryptogenic fibrosing alveolitis in children.

Cryptogenic fibrosing alveolitis (CFA) in children is supposedly a rare diffuse lung disease characterized clinically by tachypnoea, cough, poor weight gain, and cyanosis. Histologically, it is characterized by thickening of alveolar walls and infiltration of the alveolar septae with mononuclear cells and fibrous tissue. The condition is more acute in children, with fulminant course. Ten children were diagnosed as having CFA out of three hundred children seen over a period of 3 years. Diagnosis was established by characteristic clinical findings and laboratory evaluation. All the children had tachypnoea at rest and bilateral crepitations in the absence of fever. Diffuse bilateral persistent irregular shadows were noted on the chest X-ray of these children. Pulmonary function studies revealed a restrictive type of abnormality with low transfer factor for carbon monoxide in six children. Open lung biopsy was done in eight children. The biopsy material was graded according to nine morphologic variables. Administration of steroids early in the course of illness resulted in amelioration of symptoms in 60% of the patients.

Systemic lupus erythematosus in North Indian Asians. A prospective analysis of clinical and immunological features.

One hundred and one patients with systemic lupus erythematosus (SLE) from North Indian stock are presented. The clinical manifestations, laboratory parameters, causes of death, and survival are compared and contrasted with the other major reported series. SLE of North Indian Asians has several features comparable to those reported from the West, but other features are more similar to the SLE seen in Mongoloid races.

Late resistance to corticosteroids in nephrotic syndrome.

Corticosteroid resistance appeared late in the course of relapsing nephrotic syndrome in 12 patients who previously had steroid-sensitive relapses for 0.8 to 13 years. In 11 patients, renal histology performed earlier in the course of the disease showed minimal change in eight, mesangial proliferative glomerulonephritis (MesPGN) in two, and focal segmental glomerulosclerosis (FSGS) in one. Renal biopsy in another patient and a repeat procedure in four of eight patients who initially showed minimal change was done after they had developed steroid resistance, and showed FSGS. Cyclophosphamide was given to 11 patients after they became steroid resistant, and induced remission in eight that continued for 1 to 2 years in two patients. The other six had relapses that were steroid sensitive, but three of them (two with FSGS and one with MesPGN) later became resistant to steroids as well as to cyclophosphamide. Of six patients with FSGS, four with initial or subsequent resistance to cyclophosphamide eventually developed renal insufficiency. The other two have remained in remission for 12 to 16 years; one of these did not receive cyclophosphamide. Our observations suggest that patients with late steroid resistance comprise a heterogeneous group; those with FSGS and resistance to cyclophosphamide therapy may have a poor outcome.

Tuberculosis and renal transplantation--observations from an endemic area of tuberculosis.

Ninety-five renal transplant recipients from an endemic area of tuberculosis were investigated to find out the prevalence and course of tuberculosis in pre- and post-transplant periods. Eleven patients had tuberculosis in the pre-transplant period - pulmonary (2), pleural (2), miliary (1), abdominal (2), lymph node (5) and pericardial (1). They were transplanted after antituberculous therapy of 3 to 6 months with satisfactory results. The anti-tuberculous treatment was usually continued for 2 years. Only one of the above 11 patients had evidence of tuberculosis in the post-transplant period. Nine patients developed tuberculosis for the first time in the post-transplant period - pulmonary (4), pleural (1), miliary (1), lymph node (4) and pericardial (1). There was no mortality due to tuberculosis. Thorough search for tuberculosis is mandatory both during pre-transplant assessment and post-transplant follow-up in areas of endemic tuberculosis.
