Validation of a 6 item cognitive impairment test with a view to primary care usage.

OBJECTIVE: To validate the 6 Item Cognitive Impairment Test (6CIT) against the Mini-Mental State Exam (MMSE) with a view to usage as a screening tool. DESIGN: Three groups with varying levels of dementia were tested using the MMSE, 6CIT and Global Deterioration Scale (GDS). SETTING: Testing was carried out within Wiltshire, both in the community and outpatients. SUBJECTS: Patients were selected from a hospital database of dementia patients and were stratified into two groups according to GDS; a control group was also tested. RESULTS: Two hundred and eighty-seven patients were tested: 135 controls (GDS 1-2), 70 with mild dementia (GDS 3-5) and 82 with more severe dementia (GDS 6-7). The 6CIT and MMSE were found to correlate well, r(2)=-0.911 (p<0.01), when all groups were analysed. Correlation falls to r(2)=-0.754 (p<0.01) in the mild dementia group. In the GDS 3-5 group, the MMSE has a sensitivity and specificity of 51.43% and 100% respectively (cutoff 23/24). The 6CIT gives a sensitivity and specificity of 78.57% and 100% (cutoff 7/8). CONCLUSION: The 6CIT is a brief and simple test of cognition, which correlates well with the MMSE but outperforms it in milder dementia. The MMSE is of little value as a screening test for dementia.

Acute AIDS retrovirus infection. Definition of a clinical illness associated with seroconversion.

In the course of a prospective immunoepidemiological study of homosexual men in Sydney, seroconversion to the AIDS-associated retrovirus (ARV) was observed in 12 subjects. Review of the clinical files defined an acute infectious-mononucleosis-like illness in 11 subjects. The illness was of sudden onset, lasted from 3 to 14 days, and was associated with fevers, sweats, malaise, lethargy, anorexia, nausea, myalgia, arthralgia, headaches, sore throat, diarrhoea, generalised lymphadenopathy, a macular erythematous truncal eruption, and thrombocytopenia. In 1 subject an incubation period of 6 days after presumed exposure to ARV was determined and in 3 subjects seroconversion took place 19, 32, and 56 days after onset. Comparison of T-cell subsets before and after the acute illness showed inversion of T4:T8 ratio in 8 subjects, due to increased numbers of circulating T8+ cells. These findings support the notion of an acute clinical, immunological, and serological response to infection with ARV which should be considered in the differential diagnosis of mononucleosis-like syndromes in groups at high risk for the development of AIDS.
