Viral infections in 47 CVID patients in allergy and immunology department of Rasool E Akram hospital in Tehran

خلاصه انگلیسی

Background: CVID is a heterogeneous primary immune deficiency with infectious, autoimmune and autoinflamatory features. It is most common symptomatic PID in Iran, with prevalence of 1 in 25000 to 50000 people. CVID has been divided into some phenotypes to produce more homogenized subpopulations. CVID is not a pure Ab deficiency .and because of both abnormalities in Tcell and innate immunity in combination with B cell dysfunction these patients are predisposed to viral and opportunistic infections. Method: prevalence of viral infections is reported in 47 CVID patients registered in Rasool E Akram hospital in Tehran. Patients have been diagnosed as CVID with the PAGID-ESID diagnostic criteria in our department or referred from other clinics for follow up and treatment. Diagnosis of viral germs has been made by clinical signs, pathological significances and in some cases by PCR. Cases: 9 patients (19%) had problems with viral infections. Infections occurred befor diagnosis of CVID in some cases or after that. Four patients (8.5 %) had problems with wart. Sever mucocutaneus HSV infection has occurred in 3 (6 %), recurrent zona in one (2 %) and CMV infection as colitis or pneumonitis in 3(6 %) patients. Sever progressive lethal CNS infection with JC virus occurred in one patient. Conclusion: evidences show that CVID is not a pure B cell defect, and we should be aware of opportunistic and viral infections that in some cases may be fatal.
