Gender-based treatment outcomes in diabetic hypertension.

BACKGROUND: In developing countries, gender-based treatment disparities in cardiovascular preventive therapy have received little attention. AIMS: To evaluate the gender-based differences in cardiovascular disease risk profile, drug prescribing pattern, and blood pressure (BP) and glycemic control rates in diabetic hypertensives treated at primary care setting in Bahrain. SETTINGS AND DESIGN: A retrospective study at primary care setting. MATERIALS AND METHODS: An audit of the medical records of 392 diabetic hypertensives (127 men, 265 women). RESULTS: BP and glycemic targets were achieved in < 10% and < 13% of diabetic hypertensives, respectively. Angiotensin converting enzyme inhibitors monotherapy was more often prescribed in males. Apart from this, no significant differences in prescribing pattern were observed between male and female diabetic hypertensives treated with either antihypertensive mono or multidrug therapies. With the exception of insulin which was more often prescribed to females, a similar prescribing pattern and rank order of antidiabetics, either as monotherapy or combinations, was observed in both genders. The majority of diabetic hypertensives were at high cardiovascular risk. The body mass index and total cholesterol level were greater in females. Prescribing lipid-lowering drugs and aspirin were suboptimal; aspirin was more often prescribed to males. There was no gender-based difference with regard to the use of lipid-lowering drugs. CONCLUSIONS: BP and glycemic controls were suboptimal in both male and female diabetic hypertensives treated by primary care physicians. Cardiovascular disease preventive strategies have received little attention regardless of gender or other risk factors. Gender-based treatment inequities also need to be addressed.

Microbiological infections in HIV positive Bahraini patients with low CD4+ T-lymphocyte count.

The correlation of CD4+ T-lymphocyte count and the distribution of pathogenic or opportunistic microbial infection most commonly found in HIV positive individuals differ from one area to the other. The present study reports such findings in 67 HIV positive Bahraini patients in the period May 1997 to Nov. 1998. CD4+ T-lymphocyte count was measured using flow cytometry. Bacterial and fungal cultures were performed. Serological diagnosis was performed when indicated. Viral study was done serologically. The distribution of CD4+ T-lymphocyte count in the studied group was: 21 patients (31.3%) less than 100 cells/microl, 5 patients (7.5%) 100-200 cells/microl, 25 patients (37.3%) 201-500 cells/microl and 16 patients (23.9%) with count more than 500 cells/microl. Among patients with low CD4 count (less than 100 cells/microl) (n=21), microbial infections varied from fungal infections 66%, bacterial infections 57% and viral infections 4.8%. Bacterial infections included Salmonellosis (14.3%), Staphylococcus epidermidis (14.3%), Pseudomonas aeruginosa (9.5%), H. influenzae (9.5%), Legionellosis (4.8%) and E. coli (4.8%). Fungal infection included Candida albicans (52.4%), Pneumocystis carinii (9.5%), Cryptococcus neoformans (4.8%). Viral infection included H. simplex to (4.8%). Fungal infections were the highest common infection in thus study. The most common microbial infection was Candida albicans. P. carinii and Cryptococcus neoformans were less common than found in other studies world wide.

Epidemiology of HIV and AIDS in Bahrain.

Between 1986 and 1996, 378 HIV cases were identified in Bahrain, of whom 51% were foreign nationals. Intravenous drug abuse was a major risk factor (38.8%) among Bahraini nationals, while transmission through sexual contact was more common (45.7%) among foreigners. Other well known risk factors were also represented in the two communities. The male to female ratio for the two communities were very different with 10:1 for nationals compared to 1:1.4 for foreigners. Among the AIDS defining manifestations, Pneumocystis carinii pneumonia was the commonest (50%), followed by tuberculosis (21%), oro-esophageal candidiasis, cryptosporidiosis and toxoplasmosis. Transmission through sex and maternal-foetus route could emerge as significant contributors in the spread of AIDS in Bahrain unless appropriate preventive steps are taken.

Intestinal parasites in the state of Bahrain.

Intestinal parasites infections are common in the state of Bahrain, but the incidence is decreasing due to improvement in health and social standards. A community-based study sample of all population of Bahrain was done including all ages and nationalities. From 1st July 1984 to 28th February 1986, the first community-based study sample of all population of Bahrain was done including all ages and nationalities. A total number of 2123, about 0.006 of the population of 1981 census was chosen for the study. The study shown that 739 persons were infected with intestinal protozoa and helminths. The figure representing 34.8% of total sample size, whom 283 persons were symptomatic, about 38.3% of total infected sample size. Giardia lamblia and Trichuris trichuria were the most common parasites among the infected persons.

HIV antibodies among intravenous drug users in Bahrain.

A 12-month study was conducted to identify risk factors for human immunodeficiency virus (HIV) infections among intravenous drug users (IDU) attending drug rehabilitation clinic of the Psychiatric Hospital, Manama, Bahrain. Patients provided demographic and behavioural information based on a questionnaire. Two hundred and forty male IDUs participated in the study on voluntary basis. The seroprevalence of HIV was 21.1 per cent. The presence of HIV antibody was associated with educational status, frequency of injecting drugs and needle sharing.
