Frequency of Acute Kidney Injury (AKI) among patients presenting with Organophosphate Poisoning at National Poison Control Centre, Karachi: A prospective cross-sectional survey.

Background and Objective: Organophosphates poisoning is among the most prevalent forms of intentional and unintentional poisoning in Pakistan. However, the actual burden of AKI secondary to organophosphate poisoning in Pakistani population is still not known. This study aimed to determine the actual burden of AKI among patients admitted at National Poison Control Centre, Karachi. Methods: A cross-sectional survey was conducted at National Poison Control Centre, Karachi November, 2013 to April, 2014. A sample of 300 patients of age 18 years and above, presenting with organophosphate poisoning within 24 of exposure or ingestion were included in the study. Frequency of acute kidney injury was calculated using the diagnostic criteria of serum creatinine level of >1.4 mg/dL. Data was analyzed using SPSS version 19. Results: The frequency of AKI which was defined as creatinine level >1.4 mg/dL was 22.3% (n=67). However, there was no statistically significant difference was found in frequency of AKI on the basis of age, sex, amount of organophosphates ingested and BMI. This study found statistically significant differences in the AKI frequency on the basis of lag time. Those who presented earlier after poisoning had relatively low frequency of AKI. Conclusion: This study concludes that AKI is a common complication among patients presenting with organophosphate poisoning at National Poison Control Center, Karachi. Lag time is a key determinant of AKI among patients with organophosphate poisoning. Timely treatment can prevent this critical complication among patients with organophosphate poisoning.

Laurence Moon Bardet Biedl Syndrome with anaemia.

Laurence Moon Bardet Biedl Syndrome is a rare genetic disorder. Consanguineous marriage is usually the common cause. Principal features of Bardet Biedl Syndrome are red cone dystrophy, obesity, polydactyl, hypogonadism and renal anomalies. The diagnosis was overlooked in our patient until he came in our hospital. We here report an infrequent case of autosomal recessive disorder with Anaemia.

Malarial hepatopathy in falciparum malaria.

OBJECTIVE: To evaluate the clinical, biochemical and sonographic changes in patients with falciparum malaria and jaundice. STUDY DESIGN: A case series. PLACE AND DURATION OF STUDY: This study was conducted at Medical Unit-I (Ward 5), Jinnah Postgraduate Medical Centre, Karachi, from January 2006 to November 2007. METHODOLOGY: A total of 62 adult patients, regardless of age and gender, with peripheral blood film evidence of falciparum malaria, who had jaundice, were included. Any patient with evidence of infection with Plasmodium vivax or other causes of liver disease (e.g. viral hepatitis, cirrhosis, portal hypertension, amoebic liver abscess, unexplained hepatomegaly, ascites, history of alcoholism, taking hepatotoxic drugs, past history of jaundice) was excluded on the basis of history, relevant clinical examination and investigations. RESULTS: Age of the patients ranged from 13-48 years (mean 26.04+/-8.33). All patients were febrile and icteric, with pallor in 67.7%, hepatomegaly in 30.6%, splenomegaly in 70.9% and impaired consciousness in 20%. Serum bilirubin levels ranged from 3 to 24 mg%. Thirty two (51.6%) had serum bilirubin 3-6 mg%, 20 (32.2%) had 6-10 mg% and 10 (16.1%) had >10 mg%. ALT levels ranged from 20-870 IU/L and AST levels 24-1210 IU/L respectively. INR ranged from 1-1.3. Twenty eight patients (45%) had predominantly conjugated or mixed hyperbilirubinemia and serum transaminases were more than three times normal. Ultrasonography revealed hepatomegaly with decreased echogenicity in 22 (35.4%), splenomegaly in 48 (77.4%) and both hepatomegaly and splenomegaly in 16 (25.8%). Gallbladder wall thickness was increased in 5 (8.06%) patients. There was no evidence of biliary dilatation. CONCLUSION: A significant percentage of patients having falciparum malaria with jaundice fulfill the criteria for malarial hepatopathy. It should be considered in patients presenting with acute febrile illness with jaundice so that specific treatment can be given.
