The changing spectrum of severe falciparum malaria: a clinical study from Bikaner (northwest India).

BACKGROUND & OBJECTIVES: Recently there were reports from all over India about changing spectrum of clinical presentation of severe malaria. The present study was planned to study the same in the northwest India. METHODS: This prospective study was conducted on patients of severe malaria admitted in a classified malaria ward of a tertiary care hospital in Bikaner, Rajasthan (northwest India) during 1994 and 2001. It included adult patients of both sexes belonging to all age groups. The diagnosis of Plasmodium falciparum was confirmed by demonstrating asexual form of parasites in peripheral blood smear. All patients were treated with i.v./oral quinine. The specific complications were treated by standard WHO protocol. The data for individual complications for both the years were analysed by applying chi-square test. RESULTS: In a prospective study in 1994 the spectrum of complication was dominated by cerebral malaria (25.75%) followed by jaundice (11.47%), bleeding tendencies (9.59%), severe anaemia (5.83%), shock (5.26%), Acute respiratory distress syndrome-ARDS (3.01%), renal failure (2.07%) and hypoglycemia (2.07%) whereas in 2001 it was dominated by jaundice (58.85%) followed by severe anaemia (26.04%), bleeding tendencies (25.52%), shock (10.94%), cerebral malaria (10.94%), renal failure (6.25%), ARDS (2.08%) and hypoglycemia (1.56%). The sharp difference for presence of jaundice and severe anaemia in 2001 and cerebral malaria in 1994 was statistically significant. Similarly, the important cause of mortality in 2001 was multiple organ dysfunction syndrome (71.10%) with predominant presentation of jaundice and renal failure, whereas in 1994, it was cerebral malaria (77.96%). INTERPRETATION & CONCLUSION: The observation of changing spectrum of severe malaria in this study and a significant increase in presentation with jaundice as an important manifestation is highly essential for primary, secondary and tertiary level health care providers for proper diagnosis and management.

A case series of splenic infarction during acute malaria in northwest Rajasthan, India.

Malaria is a rare cause of splenic infarction. Only a few cases have been reported worldwide, mostly associated with Plasmodium falciparum infection. Here we report a series of four acute malaria patients with splenic infarction, two with P. vivax infection, one with P. falciparum and one with a mixed infection (P. vivax and P. falciparum). This small case series suggests that if a patient with malaria is complaining of left upper quadrant abdominal pain, pleuritic left lower chest pain and/or enlarging tender splenomegaly during treatment, splenic infarct should be suspected and managed accordingly to avoid further life-threatening complications.

Rediscovery of severe saw-scaled viper (Echis sochureki) envenoming in the Thar desert region of Rajasthan, India.

OBJECTIVES: In India, venomous snakebite remains an enigma. Although ineffective first aid treatments that are centuries old continue to be used by people bitten by snakes, important factual information, such as the importance and uniqueness of bites by the northern saw-scaled viper (Echis sochureki), has been largely lost and forgotten. In this paper, we report the first systematically gathered data on the clinical course of envenoming by E sochureki in Rajasthan, India. Clinical information is reported on 12 victims bitten by definitively identified E sochureki, and 2 clinical cases are described in greater detail to illustrate the severity of envenoming by this snake. METHODS: A data collection form was developed and used to prospectively gather clinical information regarding patients who were bitten by E sochureki and who brought the dead snake with them to hospital. All snakes were definitively identified by an experienced herpetologist. Information on symptoms and signs, management (both first aid and hospital), and outcomes was collected. RESULTS: All 12 victims had evidence of systemic envenoming, including abnormal 20-minute whole blood clotting tests (with systemic bleeding in 7). All received polyvalent antivenom made, in part, with Echis carinatus venom from southern India. Antivenom was relatively ineffective in restoring coagulation to these patients. All patients survived, although 1 patient suffered an intracranial bleed with residual hemiparesis. CONCLUSIONS: Echis sochureki causes severe bites in Rajasthan. Work needs to be done to alter the first aid practices used for snakebites in this area, to encourage more rapid presentation to hospital, and to develop antivenom that is more effective against E sochureki.
