Monitoring the adverse profile of atenolol--a collaborative study.

Atenolol, a cardio selective beta-adrenergic blocker, frequently prescribed in various cardiac ailments, has not been thoroughly investigated for its adverse reaction profile in Indian patient. The present ADR monitoring study which was open, prospective and collaborative was therefore planned. A total of 440 patients with various heart disease were enrolled after a strict inclusion and exclusion criteria from Maulana Azad Medical College, New Delhi and J.N. Medical College, Aligarh. fifteen patients dropped out leaving 435 for final analysis. Cold extremities occurred in 1.18% headache and dizziness in 1.41% breathlessness in 0.94% oedema in 0.70% and bradycardia in 0.47%. Adverse drug reaction in our study were less than those reported from Western countries. Better patient selection, optimal dose could have reduced the frequency of ADR in the present study. Racial factor and season might be operating to bring down ADR to atenolol in Indian patients.

Adverse reactions to propranolol, a non-selective beta-adrenergic blocking agent in hypertensive patients--a collaborative study.

Propranolol, a nonselective beta-adrenergic blocking agent, although prescribed frequently, has not been monitored for its adverse reactions in Indian population. A collaborative ADR monitoring study was planned in 2661 hypertensive patients. Exclusion criteria were associated circulatory insufficiency, heart block, left ventricular failure, diabetic mellitus and airway obstruction. The incidence of ADR was 2.1%, which is lower than reported incidence of 8.7 to 43.7 percent in other studies. This could be attributed to improper selection of patients, differences in methodology of monitoring, or to racial variation. In the present study ADR of fatigue (1.1%), dizziness (0.4%) and headache (0.2%) constituted the bulk. Additional reaction of pain in chest (0.2%), heart block (0.1%), hypoglycemia (0.1%), loss of libido (0.1%) and shock (0.03%), were also observed.

Value of splenic aspirate in the diagnosis of hairy cell leukaemia.

We present a case with hairy cell leukaemia which was diagnosed on a splenic aspirate. The patient refused splenectomy.

Prognostic significance of pre discharge one hour electrocardiographic monitoring in patients recovering from acute myocardial infarction.

During a 15 months period, 97 patients with AMI were monitored continuously at hospital discharge for one hour. The VPCs or no VPC noted during this period of continuous monitoring were correlated with subsequent cardiac events during one year follow up. Patients with complicated VPCs had a significantly higher incidence of cardiac deaths and non-fatal re-infarctions during one year follow up (54.5%) as compared to patients with no VPCs (6.5%) (p less than .001). Patients with higher grades of VPCs had more complicated course (30.3% to 66.7% for Lown Grade II to IV) as compared to 6.5% and 20.8% for grade Lown O and I. Though, the results of this 1 hour continuous monitoring at hospital discharge are not as sensitive as with ambulatory Holter monitoring as is evident from this study where complicated VPCs were detected in 11.4% patients vs. 33% with Holter monitoring, it could be a useful tool in institutions where the facility of Holter monitoring does not exist.
