Double blind, placebo controlled trial on the cytoprotective effect of misoprostol in subjects with rheumatoid arthritis, osteoarthritis and seronegative spondarthropathy on NSAIDs.

Ninety arthritic patients were randomly allotted to receive misoprostol 200 micrograms thrice daily or placebo, for 4 weeks, while they were started on various NSAIDs. While upper gastrointestinal symptoms occurred equally in both groups, patients on placebo had significantly more post-therapy abnormal endoscopy findings. Misoprostol was well tolerated without any adverse side effects; it did not interfere with the therapeutic efficacy of the NSAIDs. Arthritic patients requiring long term NSAID therapy appear to benefit from misoprostol because of its cytoprotective effect on the gastrointestinal mucosa.

Progressive systemic sclerosis in south India.

Seventy eight patients with progressive systemic sclerosis (PSS) were seen over a period of 14 years. They were analysed after clinical, haematological, biochemical, immunological and radiological investigations for comparison with other Indian and Western studies. Nine of the 78 were cases of childhood PSS. There was a female preponderance (3.9:1) and the peak age of occurrence was the 4th decade (32.1%). Arthralgia (53.8%) and skin thickening (70.5%) were the common presenting symptoms. Raynaud's phenomenon (28.2%) was less common. Involvement of the skin was present in all the patients and skin biopsy was positive in 96% of the cases. Joints were affected in 66.7%; internal organs were involved in 52.6%. Antinuclear antibody was positive in 56.8%. Abnormal echocardiography (37.6%) and barium studies (20.4%) were seen. Restrictive airway pattern by pulmonary function test was present in 55%. Death occurred in 5 patients, of whom 3 died of severe pulmonary hypertension.

Pattern of rheumatic diseases in south India. V. Ankylosing spondylitis. A clinical and radiological study.

One hundred and two patients from South India with primary ankylosing spondylitis (AS) were analysed clinically and radiologically. The mean age of onset was 26 years, with a male to female ratio of 16:1. Eleven patients presented as juvenile ankylosing spondylitis. The mode of presentation of AS included axial involvement in 59, peripheral arthritis in 38, heel pain in 18 and acute anterior uveitis (AAU) in 11. The overall incidence of extra axial features was high (90 patients). These included subjects with peripheral arthritis (49), heel pain (35), AAU (14), rib pain (11), aortic regurgitation (8), apical pulmonary fibrosis (5), mitral regurgitation (2) and conduction defects (2). Peripheral arthritis was characteristically asymmetrical and oligo articular, and involved lower limb joints. No renal involvement was noticed. Radiologically, bilateral sacroilitis was seen in 80% of cases.

Pattern of rheumatic diseases in south India. IV. Clinical profile of juvenile rheumatoid arthritis.

An analysis of 100 consecutive cases of juvenile rheumatoid arthritis from South India revealed a male preponderance (62%), a lower incidence of the systemic onset variety (10%) and equal incidence of systemic features when compared with the West. Knees and ankles were the joints commonly involved. The incidence of elevated erythrocyte sedimentation rate and C reactive protein, with haemoglobin levels below 10 g/dl was highest in the systemic onset variety. The polyarticular and systemic onset group responded well to aspirin, while the pauciarticular group responded well to indomethacin.

Acute renal failure following rifampicin.

3 cases of renal toxicity to Rifampicin are reported. All cases recovered following therapy, two required haemodialysis. It is important that cases on Rifampicin be monitored for renal toxicity and appropriate measures taken in time to prevent a fatal outcome, if detected.
