Evaluation of a serological test for tuberculosis.

The agglutination test of Nicholls was found to be ineffective in diagnosing active tuberculosis. A positive result (titre of 1/125 or more) was found in the serum of 74 (70%) out of 105 patients with newly diagnosed, smear-positive pulmonary tuberculosis; 61 (62%) out of 98 healthy family contacts; and 19 (63%) out of 30 patients with non-tuberculous conditions. These findings were not due to faulty technique since the results obtained at Hammersmith were similar to those obtained by Nicholls's laboratory in the same serum samples. Twenty-seven of the tuberculous patients who had a negative result before treatment were retested two months after the start of chemotherapy but showed no evidence of a rising titre.

Effect of Lactobacillus supplementation on immune status of malnourished pre-school children.

The present study was undertaken to assess the effect of Lactobacillus supplementation on immune response of pre-school children. Thirty malnourished (grade I and grade II) pre-school (3-5 years old) children were selected for the study. These were further categorized into three groups 'A', 'B' and 'C', each group comprising of 10 individuals. Groups 'A' and 'B' were given lactobacillus supplementation 1.0 x 10(8) million viable spores/day/child and 2.0 x 10(8) million of viable spores/day/child for 90 days respectively. Group 'C' served as control. Serum adenosine deaminase (ADA) which is an important immuno enzyme marker for assessing lymphocyte function and proliferation was determined at different intervals. The results revealed that lactobacillus supplementation at level of 1.0 x 10(8) million viable spores/day/child for 15 days along with regular diet significantly improved the ADA levels of pre-school children indicating therapeutic value of lactobacillus as supplementation to malnourished pre-school children.

Clinical profile of sickle cell disease in Orissa.

Children comprised 52% of patients with Sickle Cell Disease (SCD). Types of Sickle Cell Disease encountered were SS (92.7%). SB thalassaemia (6.7%) and SD disease (0.7%). The disease was widespread in almost all castes and communities in the society; largest number of patients (20%) belonging to scheduled castes and only 1.4% were from scheduled tribes. Maximum number of cases were in the age group 2-4 and 4-6 years, many of whom died around this age. Besides attacks of pain, jaundice and anemia, frequent attacks of fever with anemia or only anemia in childhood were a predominant presenting feature. Splenic sequestration was frequent (10.1%). The patients usually had a steady state hemoglobin level of 6-10 g/dl, with which they thrived well. Fetal hemoglobin was 5-30%. Blood transfusion was not a frequent requirement, but prophylactic long acting penicillin was helpful in preventing frequency of crisis.

Antibodies to Orientia tsutsugamushi, Rickettsia typhi and spotted fever group rickettsiae among febrile patients in rural areas of Malaysia.

A serosurvey was conducted in 1995-97 among 1596 febrile patients from 8 health centres in Malaysia for antibodies against Orientia tsutsugamushi (OT), Rickettsia typhi (RT) and TT118 spotted fever group rickettsiae (SFGR) by using an indirect immunoperoxidase assay. A total of 51.4% patients had antibody against at least 1 of those rickettsiae. Antibody to SFGR was most prevalent (42.5%), followed by RT (28.1%) and OT (24.9%). The seroprevalences of antibodies to SFGR, RT or OT alone were 12.4, 3.6 and 4.3%, respectively. Antibodies against more than 1 species of rickettsiae were presence in 31.1% of the patients, suggesting the possibility of co-infection, previous exposures or serological cross-reactivities. Seroprevalence of the various rickettsiae varied according to locality, with SFGR antibodies being the most prevalent in most areas. There was no significant association of prevalence of rickettsial antibody with gender. The seroprevalence of OT, SFGR and RT increased with patient age but an increase of antibody titre with age was not significant. Those working in the agricultural sectors had significantly higher seroprevalence of OT, SFGR and RT than those not related with agricultural activities. Scrub typhus remains a public health problem with an estimated annual attack rate of 18.5%. Tick typhus and murine typhus as shown in this serosurvey appear much more widespread than scrub typhus in this country.
