Anaemia in human African trypanosomiasis caused by Trypanosoma brucei rhodesiense.

OBJECTIVE: To find out if indeed anaemia is a major sign in human trypanosomiasis caused by Trypanosoma brucei rhodensiense. DESIGN: A one year cross-sectional study of all admitted and surveyed Trypanosoma brucei rhodensiense infected patients (June 2001-June 2002) SETTING: Nkhotakota District Hospital-Central Region of Malawi. RESULTS: After survey and investigations, 28 patients (16 males and 12 females) were admitted to Nkhotakota District Hospital with a parasite positive Trypanosoma brucei rhodensiense infection. Twenty four (85.7%) of them were anaemic. Their mean haemoglobin was 8.96 +/- 3.07 g/dl compared to controls that had a mean haemoglobin concentration of 12.17 +/- 1.35 g/dl (p < 0.000001, 95% CI -4.342 to -2.0785) (n = 45). None of the trypanosomiasis infected individuals had schistosomiasis or hookworms. Two patients had malaria. One of them was an 18-year-old pregnant woman with hepatosplenomegaly, who developed ante partum haemorrhage. She was jaundiced and had haemoglobin of 10 g/dl. She died after two weeks following the diagnosis and treatment. The other was a two-year-old girl who had haemoglobin of 8.4 g/dl. She also had hepatosplenomegaly. All the other patients looked well nourished with no other signs of chronic diseases. Hepatosplenomegaly was significantly related to the severity of illness (p = 0.011) but not to anaemia. CONCLUSION: Though basic, this study has shown that anaemia is indeed a complication of human Africa trypanosomiasis caused by Trypanosoma brucei rhodesiense. There is need for further investigation to investigate the type of anaemia that is caused by this disease.

Leprosy in Nkhotakota District Hospital.

OBJECTIVE: To study the profile of leprosy cases at Nkhotakota District Hospital in Central Region of Malawi. DESIGN: Retrospective cross-sectional study of all registered cases of leprosy from records over a nine year period (January 1992 to April 2001) SETTING: Nkhotakota District Hospital-Central Region of Malawi. RESULTS: In total 526 cases of leprosy were identified from the records. The prevalence rates gradually increased from 0.998 per 10,000 cases in 1992 to 3.39 cases per 10,000 in 1995. There was however a gradual decline of prevalence rates from 1997/1998 that had 3.17 cases per 10,000 to 1.3 cases per 10,000 in 2001. 1996 registered 2.34 cases per 10,000. Fifty seven cases (10.8%) were found with children of the age of 14 or below and 469 (89.2%) cases were of adults. Paucibacillary leprosy presented with more cases than multibacillary leprosy (p < 0.0000001). There were 80 (15.2%) cases of multibacillary leprosy compared to 446 (84.8%) cases of paucibacillary leprosy. In addition more males were affected by multibacillary leprosy than females (p < 0.0001) and females were more affected by paucibacillary leprosy (p < 0.01) than males. CONCLUSION: The results show that paucibacillary leprosy though minor in Malawi can become endemic as paucibacillary leprosy is a reflection of leprosy contacts in the population. We therefore recommend continued epidemiological surveys of leprosy. Training in leprosy detection should be encouraged so that this disease can be totally eradicated in Malawi.

Test offering, not additional information, may increase HIV testing uptake in a knowledgeable population.

OBJECTIVES: To evaluate patient HIV knowledge and testing experience and assess the effect of an HIV informational handout on HIV testing propensity. DESIGN: Cross sectional, descriptive techniques were employed to assess demographics, HIV knowledge and HIV testing experience. A randomized controlled trial was performed to determine if an HIV/AIDS information sheet influenced testing propensity. SETTING: Blantyre Adventist Hospital Outpatient Clinic. SUBJECTS: Non-emergency patients over 18 years old attending during consulting hours. INTERVENTIONS: All subjects answered a questionnaire. For the randomized controlled trial component, half received an HIV information handout. MAIN OUTCOME MEASURES: Proportions were calculated to evaluate testing experience. Logistic regression was used to assess impact of written information and demographics on HIV testing propensity. RESULTS: 490 participants were recruited, of whom 57% had never been tested for HIV. Of the untested, 88% had never been offered an HIV test. Of those that had never been offered a test, 46% desired one. The sample was highly knowledgeable about HIV. Reading an information sheet had no impact on HIV knowledge (p=0.736 to 0.788) or desire for testing (p=0.387). However, age (OR=0.97, 95%CI (0.95,0.99)) and gender (OR=1.85, 95%CI (1.06, 3.23)) significantly correlated with testing propensity. CONCLUSIONS: A large percentage of patients who have never been offered HIV testing desire testing. More frequent HIV test offering by clinicians could improve testing rates. Clinician education programmes should be developed to increase test offering. Furthermore, written health information in a setting of high HIV/AIDS knowledge may not change behaviour. Alternative methods should be employed to encourage HIV testing uptake.
