We evaluated the relationship between CMV and human herpes virus-6 (HHV-6) reactivation and the incidence of grades 2 to 4 acute GVHD post BMT. Bronchoalveolar lavage fluid (BALF) samples extracted from 54 BMT recipients on post-BMT day 35 were analyzed by PCR for detection of CMV DNA, HHV-6 DNA and CMV plus HHV-6 DNA. CMV DNA was detected in 26 patients and 13 (50%) developed grades 2 to 4 acute GVHD. Of the 28 who were CMV negative, only six (21.4%) developed grades 2 to 4 acute GVHD. HHV-6 was detected in 18 patients, and 11 (61.1%) developed grades 2 to 4 acute GVHD. Of the 36 who were HHV-6 negative, only eight (22.2%) developed grades 2 to 4 acute GVHD. CMV and HHV-6 were detected in 13 patients, and eight (61.5%) developed grades 2 to 4 acute GVHD. Of the 23 who were negative for both CMV and HHV-6, only three (13%) developed grades 2 to 4 acute GVHD. In all experiments, the difference between the groups was significant (P<0.05, P<0.05 and P<0.01, respectively). We conclude that herpes virus infection, in particular CMV concurrent with HHV-6 reactivation, is predictive of moderate to severe acute GVHD.

Infection, including viral infection, still cause serious complication in the course of chemotherapy. Recognition of viral infections, monitoring, prophylaxis and treatment is aimed at reducing the number of infected patients, mitigating the cause of the disease and limiting deaths directly linked with infections in paediatric cancer patients. Viruses from the herpes group (HSV, VZV, EBV, CMV) are particularly dangerous. They can cause not only asymptomatic and local infectious but also general diseases and can reactivate, especially after BMT. Hepatoropic viruses (HBV, HCV) often lead to breaks in chemotherapy, while chronic viral hepatitis can lead to fibrosis, cirrhosis and even primary hepatocellular carcinoma. CMV, RSV, adenovirus influenza and parainfluenza virus cause diffuse interstitial pneumonitis and are also associated with a high rate of mortality. In this paper, we present the most frequency viral infection in children with malignant diseases, their methods of diagnosis and treatment.

We studied the clinical profile of infections among 221 pediatric patients who underwent 230 allogeneic transplants between 1986 and June 2004. All patients developed febrile neutropenia. There were 283 documented infections, which included bacterial (36.9%), viral (45.7%), fungal (11.1%) and other infections (6.3%) including tuberculosis. Bacterial and fungal infections were more common in the first 30 days following BMT, while viral infections were more common >30 days after BMT. Bacterial pathogens were predominantly gram-negative organisms (72.7%), when compared with gram-positive organisms (27.3%). Common gram-negative organisms included NFGNB, Pseudomonas, Escherichia coli and Klebsiella while coagulase negative Staphylococci was the main gram-positive organism. Bacteremia (61.2%) was the main source positive cultures and was mainly because of gram-negative organisms (81%), predominantly NFGNB and Pseudomonas. Exactly 103/221(43.7%) transplants had 128 documented viral infections commonly because of Cytomegalovirus, Herpes group of viruses and transfusion related hepatitis. Thirty of 221 (13.5%) of transplants had 30 documented fungal infections with the majority being because of aspergillus (90%). Tuberculosis was seen in 1.7% of transplants while catheter infections were seen in 21 patients (9.1%). Infection related mortality was seen in 12% predominantly because of CMV or fungal infections. A sub group analysis (pre-1998 vs. post-1998) revealed higher incidences of gram-negative infections, bacteremia and bacterial infection related mortality in the pre-1998 era when compared with the recent times. The profile and mortality of infections in this series from India is not significantly different from reports from the West.
