My husband has been suffering from recurring fever every 3rd or 4th day for the past 7 months. All blood tests are normal, esr ,crp, cultures of urine and blood all normal, chest ct full body pet heart echo all normal. Tested positive for montoux and quantiferon gold, with no symptom other than fever, was put on ATT on 4th JULY 2011 fever persists with no other symptoms. Has been on ATT for more than 4 months with no respite and as per doctor TB is ruled out but 6 month course mandatory. Please help. Fever comes with mild chills and head ache at times.
Cyclical fever every few days is one of the characteristic signs of malaria, and the length of the cycles can help identify the type of malaria. Specifically a fever every three days is indicative of Plasmodium malariae infection, which also fits with the long, chronic persistence of the illness.
This parasite can be hard to diagnose as it is often present in low concentrations in the blood. If you haven’t had a blood film done already, ask your doctor to make a thin and thick blood film to look for the presence of Plasmodium malariae in your husband’s blood.
If the first films are negative, continue with daily films for a further 2 or 3 days. Another diagnostic option is a rapid diagnostic test, which can detect antibodies to the malaria parasites in the blood. P. malariae is easily treated with chloroquine.
Unfortunately, without further information and a more complete medical history it will be impossible to make a further diagnosis of your husband’s condition, but certainly checking for Plasmodium through a blood test would be a good first step.
