Cytomegalovirus (CMV) infection involving the skin in three transplant patients is presented. Patient 1, whose infection apparently was localized only to a cutaneous wound induced by extravasated ionotropic solution, survived. Mixed CMV and Candida infections developed in patient 2 in the cutaneous ulcer. He died of disseminated herpes simplex virus infection in two weeks. Patient 3 had CMV pneumonia and purpuric maculopapular eruption. He died of Pseudomonas sepsis 17 weeks later. Eighteen cases with CMV skin lesions are reported in the English literature. The clinical findings and the outcome of the current and the reported cases are analyzed. All patients were immunocompromised. CMV infection, when detected in the skin, appears to be associated with grave prognosis. Seventeen of 20 patients whose final outcome was recorded died within six months after the onset of CMV skin lesions. The outcome of one case is unknown. The mortality was 85%. The fatal cases had either concurrent disseminated CMV infection or mixed cutaneous or systemic infections. When the infection is localized in the skin wounds, the prognosis seems fairly good. All three such patients survived.

A clinicopathological study was carried out in 200 autopsied cases experienced in our department from 1981 to 1988. Cytomegalovirus infection was detected in 18 cases (9.0%). Eleven patients were male and 7 were female, and their ages ranged from 21 to 72 with a mean of 58.1 years. Primary diseases were mainly Non-Hodgkin's lymphoma (7 cases) and Adult T-cell leukemia (4 cases), and corticosteroid had been administered to all of them. The most commonly involved organ was lung (77.8%), followed by adrenal (55.6%), esophagus, pancreas, ovary (22.2%), stomach, small intestine, thyroid (16.7%), liver, kidney, tongue (11.1%), and so on. Concomitant infections were frequently complicated, which were bacterial pneumonia (5 cases), fungal pneumonia (3 cases), disseminated varicella-zoster infection (2 cases) and herpes simplex virus esophagitis or stomatitis (5 cases), while, ten patients died of cytomegalovirus pneumonia. Cytomegalovirus infection was one of the fatal opportunistic infections in immunocompromised, especially cell-mediated immunity impaired, hosts such as the patients with lymphocytic malignancies.

Totals of 58,661,000 acute respiratory disease (ARD) cases, 1,376,651 bronchitis and pneumonia complications, and 93,042 deaths from influenza, bronchitis, pneumonia or chronic pulmonary affection were notified during 11 years of ARD surveillance from 1975 to 1986. All ARD seasons started with the first phase in September-December; this increase in morbidity was caused chiefly by adenoviruses, parainfluenza viruses, rhinoviruses and M. pneumoniae. Second wave of ARD morbidity occurring in January-April used to be explosive and was associated with an influenza epidemic in 9 of the 11 seasons; only in 1978/79 and 1984/85 the ARD epidemics were caused by adenoviruses and especially RSV, the share of influenza being minimal. Pneumonia and bronchitis excesses occured during epidemics caused by M. pneumoniae in 1975/76, 1980/81 and 1985/86. Particularly high mortality excesses occurred in 1976, 1977 and 1983 during epidemics elicited by a new drift variants of influenza A(H3N2). Identification of viral agent of M. pneumoniae attempted in 5474 ARD cases was successful at 37.4%. The respective contributions of parainfluenza viruses, adenoviruses, influenza A virus and RSV to overall aetiologically identified morbidity were 14.2, 13.9, 13.8, and 12.0%. Mixed infections (2-3 agents identified simultaneously) accounted for 14.6% of cases. Type B influenza virus, rhinoviruses, enteroviruses and herpes simplex virus contributed only by 5.6-7.8%. In ordinary seasons the share of M. pneumoniae in aetiologically identified ARD morbidity was 0.6-3.8%; this agent displayed predominance at 5-year cycles, when accounting for 20.5-38.9% of cases. The most frequently detected agents in individual age groups were as follows: in preschool children parainfluenza (18.6%), RSV (16.6%), and adenoviruses (17.4%); in school children M. pneumoniae (26%), influenza A and B (10.2 and 14.7% respectively), and adenoviruses (10.7%); in adolescents and young adults influenza type A (20.2%), M. pneumoniae (15.0%), and rhinoviruses (13.3%); in adults above 25 years age influenza A virus (38%), and other respiratory viruses at a frequency lower than 10% each.

Although there are as yet no established indications for acyclovir use in pregnancy, the most reasonable uses are for maternal infections such as disseminated herpes simplex, varicella pneumonia, and severe primary genital herpes. Other potential, but more problematic, uses during pregnancy are for uncomplicated primary genital herpes infections, maternal varicella, and for prophylaxis against the recurrence of genital herpes near term. We review each of these potential uses and the pharmacokinetics of acyclovir in pregnancy while emphasizing that at the present time, safety, efficacy, and appropriate dosage of the drug have not been established for any use in pregnancy.

Cyclosporin (CYA) is now recognized as an effective immunosuppressant to lead to a marked improvement in graft survival in organ transplant recipients. Although the incidence of infection in the CYA group has been decreased compared with that in the azathioprine group, infectious diseases in 400 kidney transplant recipients treated with CYA were noted in our single center. Treatment strategy for infectious diseases: Antibiotics and/or gamma-Globulin were administered to all recipients with bacterial infections. Aciclovir was added in recipients with herpes simplex virus (HSV) infection or varicella zoster virus (VZV) infection. Human interferon-beta (HuIFN-beta) was used in recipients who had life-threatening viral infection, especially cytomegalovirus (CMV) pneumonitis. Glycyrrhizin was used for acute hemorrhagic cystitis and nephropathy due to adenovirus (AV). Trimethoprim sulfamethoxazole and/or pentamidine were added in recipients complicated with Pneumocystis carinii (Pc) pneumonitis or in order to prevent Pc pneumonitis. Infectious diseases: One hundred and six recipients had infectious diseases 129 times in this series, seventy-six percent of all infections occurred during the first 4 months after the transplantation. Urinary tract infection (UTI), herpes zoster and pulmonary infection were the most common infectious diseases, occurring in 28.7%, 24.0% and 23.2%, respectively. Septicemia or bacteremia developed in 9 recipients, secondary to UTI in 8 and to surgical wound infection in one. Sixty-one symptomatic viral infections occurred in 57 recipients. A total of 5 recipients (1.3%) died of interstitial pneumonitis. Infectious organisms: Viral and bacterial infections were most common, occurring in 47.3% and 41.9%, respectively. Viral species detected in these recipients with the frequency were HSV 14 times, CMV 9 times, VZV 31 times and AV 7 times. 1) The incidence of viral infections in kidney transplant recipients treated with CYA is relatively high compared to bacterial infections. 2) HuIFN-beta therapy is effective in the treatment of serious opportunistic herpes virus infections, especially CMV pneumonitis. 3) Glycyrrhizin therapy is effective in the treatment of acute hemorrhagic cystitis and nephropathy due to AV and hepatic dysfunction. 4) Aerosolised pentamidine therapy is very useful for prophylaxis of Pc pneumonitis.

Three patients underwent single left lung transplantation for end-stage pulmonary fibrosis between June and November 1987. Preoperatively all were housebound, receiving continuous, supplemental oxygen, and their pulmonary function had deteriorated despite corticosteroid and cyclophosphamide therapy. Pulmonary preservation was by means of pulmonary arterial perfusion with modified Euro-Collins solution, 60 ml/kg, at 4 degrees C with adjunctive iloprost (synthetic prostacyclin) infusion. The heart from each donor was used successfully for transplantation. Good early graft function enabled extubation 11, 46, and 96 hours after transplantation. An omental wrap was used around the bronchial anastomosis, and bronchial healing was satisfactory in all. All patients had episodes of pulmonary rejection diagnosed by a combination of symptoms, chest x-ray infiltrates, the exclusion of pneumonitis by bronchoalveolar lavage, and prompt response to "pulse" steroid therapy. Two of the three patients had three episodes of opportunistic pulmonary infections: Herpes simplex pneumonitis, Pneumocystis carinii infection, and Aspergillus pneumonitis. The three patients were discharged from the hospital after 5, 6, and 7 1/2 weeks, respectively. The first and third patients remain alive and well, living essentially normal lives 24 and 19 months after transplantation with no evidence of arterial desaturation on exercise testing while breathing room air. The second patient had symptoms of deteriorating lung function with a progressive decline in forced expiratory volume in 1 second, vital capacity, and diffusion capacity despite repeated "pulse" therapy with combinations of methylprednisolone, antithymocyte globulin, and OKT3 (Ortho Diagnostic Systems Inc., Raritan, N.J.). An open lung biopsy specimen showed obliterative bronchiolitis, and this patient underwent orthotopic lung retransplantation, on the right side. Despite excellent early graft function and early extubation, he died of uncontrolled rejection and general debility after 3 weeks. This early experience in our center with two of three patients surviving 19 to 24 months, respectively, confirms the restoration of good pulmonary function and near normal life-style in patients with end-stage pulmonary fibrosis after single lung transplantation, as first reported by the Toronto Lung Transplant Group. We have used an alternative method of lung preservation (cold crystalloid pulmonary perfusion as opposed to topical cooling, used by the Toronto group), which provided excellent pulmonary preservation up to and beyond 4 hours' storage.(ABSTRACT TRUNCATED AT 400 WORDS)

We report seven elderly patients with COPD who developed serious infectious complications during prolonged treatment with high doses of corticosteroids. Infections included invasive pulmonary aspergillosis, Herpes simplex stomatitis and esophagitis, cytomegalovirus pneumonia, bacterial sepsis, fungemia and meningitis due to Cryptococcus neoformans. Each of the three patients who developed invasive aspergillus pneumonia died. The efficacy of prolonged therapy with high doses of corticosteroids in patients with COPD is not proven. These cases illustrate the potential for serious infections in patients with COPD treated with corticosteroids.

We report the case of a patient with AIDS, Kaposi's sarcoma and persistent herpes simplex type 2 proctitis who died of herpes simplex 2 pneumonitis following an episode of nonspecific interstitial pneumonitis. This rare complication of persistent herpes simplex mucosal infection must be considered in patients with AIDS suffering from severe pneumonitis with negative bronchoalveolar lavage.

We report our experience of heart-lung transplantation for the treatment of children with terminal respiratory disease. Between May 1987 and October 1988 we performed heart-lung transplantation in five children under the age of 16 (age range 11-15). All the patients were severely disabled by dyspnoea and hypoxia. Two had primary pulmonary hypertension, two cystic fibrosis, and one had Eisenmenger's syndrome. All five children are alive and well five to 17 months after operation and have returned to activities normal for their age. Three of the five patients had episodes of infection after operation. These were staphylococcal pneumonia, herpes simplex pneumonitis and, in one of the patients with cystic fibrosis, persistent purulent sputum. The mean number of episodes of rejection per child was 2.7 per half year. Heart-lung transplantation is a practical treatment for children in these disease groups with terminal respiratory failure.

Certain types and causes of pneumonia are unique to the immunocompromised host. The most frequent causes are cytomegalovirus, Pneumocystis carinii, varicella zoster virus, Candida species and Aspergillus species. Lymphoid interstitial pneumonia has recently been recognized in children with the acquired immunodeficiency syndrome. With the exception of varicella-zoster pneumonitis, an invasive procedure, such as open lung biopsy, is required to establish a definitive diagnosis. Infrequent causes of pneumonitis in immunocompromised children include Toxoplasma gondii; Cryptosporidium; Herpes simplex; adenovirus, gram-negative bacillary infections (Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Legionella pneumophilia); Nocardia spp; zygomycetes, and Cryptococcus neoformans. The discovery of any of the aforementioned pneumonias suggests the patient may have a serious underlying immunodeficiency.
