RESUMEN

OBJECTIVE: Uncertainty concerning the treatment of Stage IB2-IIA (bulky) cervical cancer is still continuing. In this study, an analysis of Stage IB2-IIA (bulky) cervical cancer was performed. The efficacy of primary radical surgery and neoadjuvant chemotherapy followed by a radical surgery was investigated. MATERIALS AND METHODS: Medical data of 50 patients who were diagnosed with Stage 1B2-IIA (bulky) cervical cancer and treated between 2002-2009 were retrospectively assessed. In the radical surgery group, radical hysterectomy + bilateral pelvic + para-aortic lymphadenectomy were performed. In the neoadjuvant chemotherapy group, a combination of cisplatin/topotecan or paclitaxel/carboplatin was given to the patients and then radical surgery was performed. Each group was evaluated individually. Prognostic factors were determined and survival rates were compared between the groups. Ap value was taken < 0.05 for the statistical significance level for all results. RESULTS: Radical surgery after neoadjuvant chemotherapy was performed in 21 and primary radical surgery in 29 patients. Median follow-up time was 36.0 +/- 14.0 months. Average of the tumor size before treatment was 50.2 +/- 7.6 mm. In the radical surgery after neoadjuvant chemotherapy group, lymphovascular space invasion (LVSI) and tumor size (before and after treatment) were determined to be significant factors for each of disease-free survival (DFS) and overall survival (OS). On multivariate analysis, tumor size (before treatment) was found to be an independent prognostic factor for both of DFS (p = 0.006) and OS (p = 0.010). No significant difference in survival periods was observed among the groups. CONCLUSION: There was no significant superiority among the two treatment options. Nonetheless, further studies are needed to compare the multimodal approaches in these stages of cervical cancer.

RESUMEN

OBJECTIVE: Uterine sarcomas (US) are rare, malignant, and aggressive tumors of the uterus. In this study the authors aimed to evalu- ate retrospectively the clinical and pathologic features and to investigate the prognostic factors of the U.S. patients who were treated in their department in the last 20 years. MATERIALS AND METHODS: The archive files, medical, and pathological records of the 132 US patients who were operated on and regularly followed up in the clinic between March 1991-March 2011 were reviewed. Clinical features, operation characteristics, pathological findings, adjuvant therapies, and follow-up data of the patients and their effects on survival were investigated. Analysis of disease-free survival (DFS) and overall survival (OS) were calculated using Kaplan-Meier and Cox regression tests. Thep value was taken <0.05 to maintain the statistical significance level for all results. Results: Seventy of the patients were diagnosed with leiomyosarcomas (LMS), 33 were with carcinosarcomas, 12 were with endometrial stromal sarcomas (ESS), nine were with undifferentiated endometrial sarcomas, five were with adenosarcomas, and three were with botryoid rhabdomyosarcomas. The average patients' age was 53.7 +/- 12.6 (17-78). About two-thirds of the patients were in postmenopausal and one-third were in pre- menopausal period. Vaginal bleeding was detected as the most common reason for patients' admission (68.9%). All cases underwent surgery and a procedure of total abdominal hysterectomy + bilateral salpingo-oophorectomy (TAH + BSO) was performed for most of them (88%). The mean duration of follow-up was 36 months (4-198). The two- and five-year OS rates were 65% and 36%, respectively, with a median time of 37 months (95% CI, 28-45). The two- and five-year DFS rates were 59% and 33%, respectively, with a median time of 29 months (95% CI, 18-40). CONCLUSION: As a result of multivariate analysis, while age, stage, lymphovascular space invasion (LVSI), and lymphadenectomy were found to be independent prognostic factors affecting DFS, only stage was detected as an independent prognostic factor for OS.

RESUMEN

Teratoma of the fallopian tube (cystic or solid) is a rarely encountered tumour and, to date, only 73 cases have been reported in the literature. A comprehensive review has not been done since 1972, when Mazzarella and colleagues reviewed 44 cases of tubal teratomas. This situation has prompted us to survey the literature to update the data on tubal teratoma cases. The majority of the tumours were benign. The tumour was cystic in nature in 50 cases. Patients' ages ranged between 17 and 67 years. None of them was diagnosed preoperatively. Half of the tumours were ≤ 5 cm, whereas the other half were > 5 cm in diameter. About two-thirds of the patients were associated with two or fewer gravidity. To the best of our knowledge, the present case included in our paper is the first tubal cystic teratoma reported from Turkey.

RESUMEN

OBJECTIVE: In this retrospective study, we compared the effectiveness and reliability of the third-line chemotherapies gemcitabine and liposomal doxorubicin, in patients with platinum-sensitive ovarian cancer (OC). PATIENTS AND METHODS: The retrospective study included platinum-sensitive epithelial ovarian cancer patients who had previously received paclitaxel and carboplatin therapy. Between 2013-2021, cross-matched 45 patients who received gemcitabine and 48 who received liposomal doxorubicin as third-line therapy were compared based on clinicopathological characteristics, biomarkers, and blood cancer antigen (CA) 125 levels. Time to treatment failure, survival, and quality of life were additional objectives. RESULTS: The study included a total of 93 patients. The reported mean survival durations for treatments, 19.45 months for gemcitabine and 17 months for liposomal doxorubicin, did not statistically significantly differ (p=0.398). The mean CA 125 levels for the liposomal doxorubicin and gemcitabine groups after treatment were 54.4±11.4 U/ml and 54.7±11.1 U/ml, respectively. There was no noticeable difference between the treatments when comparing the postop CA 125 value (p=0.37). CONCLUSIONS: For both pegylated liposomal doxorubicin (PLD) and gemcitabine as single agents in the third line, our data revealed comparable effectiveness results, and there was no substantial difference in progression-free survival (PFS) for recurrent ovarian cancer. These therapies were tolerated with an expected incidence of hematological toxicities.

RESUMEN

OBJECTIVE: To evaluate the clinicopathologic characteristics, methods for preoperative evaluation, prognostic factors, and overall survival of nongenital ovarian metastases (NGOM). MATERIAL AND METHODS: Forty-eight patients with NGOM followed between January 2001 and January 2009 in Cukurova University Department of Gynecologic Oncology were included in the study. Clinical characteristics including demographics, preoperative imaging methods, endoscopic evaluations, tumor markers, histopathologic findings, prognostic factors, types of surgery, modalities for adjuvant therapy and survival were analyzed. RESULTS: The gastrointestinal tract is the most common location of the primary tumor; colonic origin was found in 41% of the patients (n = 20). All metastatic lesions were adenocarcinoma with 23% of these classified as Krukenberg and 29% as mucinous type adenocarcinoma. When the whole group was evaluated, median survival time was 15.7 months in patients and there were significant differences between the groups according to primary site. Histopathological subtypes and presence of peritoneal carcinomatosis affected the median survival. The significant prognostic factors were primary site and histopathologic subtypes of the NGOM. CONCLUSIONS: NGOM should be kept in mind to avoid inappropriate management and therapy in patients with surgically managed ovarian tumor, especially young patients with gastrointestinal complaints.

RESUMEN

Recent studies suggest that beta-adrenergic blocking agents show promise in the management of cardiomyopathies; however, their role in acute myocarditis is unknown. One hundred 3 week old mice were infected with coxsackievirus B3 and were given either metoprolol (n = 50) or normal saline solution (n = 50) intraperitoneally for 10 days. Twenty mice from each group were observed for mortality for 30 days. Of the remaining 60 mice, 10 from each group were killed on day 3, 6 or 10 and examined for heart viral titers and pathologic changes. Mortality rate in the metoprolol group was 60% compared with 0% in the saline group (p less than 0.005). Viral titers on day 10 of infection were 10(2.6 +/- 0.2) median tissue culture infective dose for the metoprolol group versus 10(2.1 +/- 0.1) for the saline group (p less than 0.05). Whereas pathologic changes at days 3, 6 and 10 of infection were similar in both groups, on day 30 of infection, inflammation, necrosis and mineralization scores (mean +/- SEM) were 1.1 +/- 0.3, 2.1 +/- 0.4, 2.2 +/- 0.5 for the metoprolol group versus 0.3 +/- 0.1, 0.4 +/- 0.3, 0.4 +/- 0.3 for the saline group, respectively (p less than 0.01). Six noninfected mice received metoprolol intraperitoneally for 10 days; there was no mortality during 30 days of observation. In conclusion, metoprolol administration exerts deleterious effects in acute coxsackievirus B3 murine myocarditis.

RESUMEN

CD56, a neural adhesion molecule, is a marker of natural killer (NK) lymphocytes as well as a subgroup of CD8+ T cells. Normal lymphocytes with a CD56/CD4 phenotype are scarce. Physiologic increases may occur in patients with immunosuppression, chronic inflammation, and autoimmune disorders. We report 4 cases of lymphomas/leukemias with the unusual CD56/CD4 phenotype. Two were of T-cell and 2 of true NK-cell origin. The T-cell lymphomas had large granular lymphocyte morphologic features and splenomegaly. One patients had a benign course; the other died within months of the leukemia diagnosis. The 2 NK cell lymphomas had blastic morphologic features, initially involved skin, and had a very aggressive clinical course; 1 patient died of acute leukemia, and 1 had recurrence after bone marrow transplantation. Cytogenetic analyses did not show a consistent pattern of abnormalities. The NK lymphoma with acute leukemia had a t(2;5) but was CD30- and anaplastic lymphoma kinase negative. Although CD56+/CD4+ lymphomas/leukemias are a heterogeneous group, there may be a distinct subgroup of NK lymphoblastoid lymphomas of the skin, judging from our cases, as well as those previously reported.

RESUMEN

Thebcl-2oncogene plays an important role in carcinogenesis by inhibiting cell death (apoptosis). It was initially discovered in follicular B cell lymphoma with t(14,18), and subsequently found in other malignant and premalignant lesions. Alteration of the normal controls of cell proliferation is also a significant factor in the multistep process of tumorigenesis. The proliferative activity of a given lesion is commonly valuated by MIB1, a monoclonal antibody to Ki67 proliferation antigen. Immuno-histochemical (IHC) staining expression of bcl-2 and Ki67 was retrospectively investigated in a series of 52 colorectal carcinomas and 56 adenomas according to the avidin-biotin-complex method. The aim of the study was twofold: 1) to investigate any correlation between MIB1 and bcl-2 immunostaining expression in colonic adenomas and carcinomas, 2) to identify any relationship between either marker and several histopathologic parameters including tumor size, pathologic stage, lymph node metastasis, angio-lymphatic invasion, tumor grade and differentiation in colon carcinomas. Bcl-2 was consistently higher in adenomas than in carcinomas. There were 44/56 (78.6%) adenomas, and 27/52 (51.9%) carcinomas positive for bcl-2 (p=0.004). The mean Ki67 labeling index (LI) was 30.05+/-7.6 and 38.12+/-11.01 in adenomas and carcinomas, respectively (p=0.0001). Expression of bcl-2 in carcinoma was significantly associated with a lower mean Ki67 LI and with favorable histopathologic parameters. We conclude that bcl-2 oncoprotein expression is probably an early step in the process of colon carcinogenesis, and its expression may be associated with a favorable clinical course. Furthermore, an inverse relationship exists between bcl-2 and Ki67 in colonic neoplasia. Evaluation of bcl-2 and Ki67 IHC expression in colonic carcinoma should be performed prospectively to determine if their expression is of value in predicting the clinical course in these patients.

RESUMEN

OBJECTIVE: To assess the expression of coxsackievirus B3 (CB3) myocarditis in mice with pre-existing CB4 myocardial disease. DESIGN: Double blind comparative study of CB3 myocarditis in CD1 mice with or without prior CB4 induced cardiac damage. INTERVENTIONS: Antecedent myocardial injury was produced by CB4 infection intraperitoneally at age two days. Two to three weeks later, when CB4 myocarditis was established, infected and control animals were inoculated intraperitoneally with CB3. They were then sacrificed over a 45-day period. Virus and neutralizing antibody titres were measured on days 3 and 13 after CB3 infection, respectively. The incidence of myocarditis and the intensity of histopathological changes (assessed according to a semiquantitative grading scale from 0 to 4) over a 45-day period were compared. MAIN RESULTS: Among animals with prior CB4 disease, CB3 titres were lower (2.3 +/- 1.7 versus 3.6 +/- 0.8, tissue culture infective dose 50, P = 0.05) and neutralizing antibody response was slightly higher. The incidence of myocarditis was diminished (59.1 versus 89.3%, P = 0.01) and the indices of pathological changes were lower but the differences were not significant (0.68 +/- .54 versus 1.10 +/- 0.20, 1.38 +/- 0.43 versus 1.50 +/- 0.25, 0.56 +/- 0.56 versus 1.26 +/- 0.75, 0.38 +/- 0.58 versus 1.30 +/- 0.78, 0.12 +/- 0.28 versus 0.47 +/- 0.2 on days 3, 9, 13, 30 and 45 post infection, respectively, P > 0.1). CONCLUSION: These results demonstrate that prior exposure to CB4 offers some protection from subsequent CB3 infection. Moreover, they show that antecedent CB4 myocardial damage does not predispose to a worsened expression of CB3 myocarditis.

RESUMEN

Indomethacin has been shown to increase virus titers and to worsen cardiac injury in the acute phase of coxsackievirus B4 murine myocarditis. The authors evaluated the effects of indomethacin on the histopathologic changes in a later phase of this disease after virus clearance. Two-day old CD1 mice were infected with coxsackievirus B4. Ten days later, surviving animals were randomized to receive indomethacin or saline intraperitoneally for 10 days. They were then euthanatized, and their hearts were examined for the presence of inflammation, necrosis, scarring, and focal thinning. Mortality was slightly higher among treated animals (7/15 versus 2/12, p = 0.3). The index of inflammation (0.6 +/- 0.5 versus 0.7 +/- 0.5) necrosis and scarring (0.4 +/- 0.5 versus 0.3 +/- 0.5) among treated and control animals, respectively, was not significantly different, but the size of involved myocardium (149742 +/- 201982 versus 35300 +/- 45413 microns2) was remarkably larger (p less than 0.05), and focal ventricular thinning (5/12 versus 0/10, p = 0.03) was encountered among indomethacin recipients exclusively. These findings indicate that indomethacin treatment in the late phase of coxsackievirus B4 myocarditis enhances myocardial damage and increases the incidence of focal ventricular thinning.

RESUMEN

Maltodextrins are a group of oligosaccharides, which are being increasingly used as a source of carbohydrate in many commercially available foods and drinks. This study investigated the effect of three different maltodextrins on the pH of dental plaque, in vivo, in 10 adult volunteers using the plaque harvesting method. The three maltodextrins tested in this study were DE=5.5, 14.0 and 18.5 (DE=dextrose equivalents), made up as 10% solutions. Also, three commercially available maltodextrin containing children's drinks were evaluated for their acidogenicity. 10% sucrose and 10% sorbitol solutions were used as positive and negative controls, respectively. The minimum pH achieved for DE=5.5, 14.0 and 18.5 was 5.83+/-0.30, 5.67+/-0.24 and 5.71+/-0.29, respectively, and were significantly higher as compared with that for 10% sucrose (5.33+/-0.17). The area under the curve was the least for DE=5.5 (12.03+/-4.64), followed by DE=18.5 (13.13+/-8.87) and DE=14.0 (17.35+/-6.43), but were all significantly smaller as compared with 10% sucrose (24.50+/-8.64). The minimum pH achieved for the infant drinks was 6.01+/-0.24, 5.99+/-0.28 and 5.8+/-0.19 for the Lemon Barley and Camomile Herbal baby drink, Mixed Citrus and Hibiscus baby drink, and Infant Milk, respectively. It was concluded that though maltodextrins appeared to be significantly less acidogenic than 10% sucrose, they can lead to a substantial drop in plaque pH and may, therefore, have a potential to cause demineralisation of enamel.

RESUMEN

BACKGROUND: Primary malignant neoplasms of the submandibular salivary gland (SMG) are rare, and metastatic tumors are rarer. Most of the metastases are discovered months or years after the diagnosis of the primary malignancy. Despite the increasingly used fine-needle aspiration biopsy (FNAB) in the evaluation of major salivary gland masses, diagnosis of metastases by FNAB has been only rarely studied. CASE: We report a case of lung carcinoma initially presented as a SMG swelling diagnosed by aspiration biopsy. The patient is a 52-yr-old man, a 40-pack/year smoker who also complained of weight loss and blood-streaked cough. An FNAB of the mass was consistent with metastatic adenocarcinoma with prominent signet ring-cell component of unknown primary. Subsequent studies revealed a left lung mass and left pleural effusion. The effusion cytologic examination showed malignant cells consistent with carcinoma. The patient's condition deteriorated rapidly, and he died within a few days. An autopsy revealed adenocarcinoma of lung with prominent signet ring-cell component. CONCLUSION: FNAB is a rapid, safe, reliable, and cost-efficient technique for evaluation of major salivary glands lesions. To our knowledge, this case is the first lung carcinoma presenting as SMG mass initially diagnosed on FNAB.

RESUMEN

Because bronchioloalveolar carcinoma (BAC) commonly displays bland cytologic appearance, there is a good potential for misinterpretation. The aim of this study was twofold: one was to identify the most reproducible cytomorphologic features to distinguish BAC from conventional lung adenocarcinoma (CLA) on fine-needle aspiration (FNA), and the other was to investigate the staining characteristics of these two variants of lung carcinoma with P53 tumor suppressor gene immunostain and their potential value in the distinction between the two entities. Cytology records of 13 histologically documented BACs was retrieved: 7 FNA, 3 bronchial washing/bronchial brushing (BW/ BB), and 3 scraping smears of surgical specimens. Two cases had both FNA and BW/BB material. Immunostains for P53 protein, carcinoembryonic antigen (CEA), and Ki67(MIB-1) monoclonal antibodies were performed on 13 BACs (FNA cell blocks and tissue) and on 11 FNA cell blocks of CLA. Cytologically, BAC showed uniform cells with abundant, lacy cytoplasm, and bland, folded nuclei arranged singly, in papillary clusters, and sheets. Immunocytochemically, one BAC and one CLA were technically unacceptable. Of the 12 remaining BAC cases, 10 were reactive with CEA, 9 reactive with Ki67 (> 5%), and 4 reactive with P53. Of the 10 remaining CLAs, 9 were positive with CEA, 9 were reactive with Ki67 (> 5%), and 8 were reactive with P53. We conclude that BAC demonstrates distinctive cytologic features, but difficulty may be encountered with well-differentiated CLA, metastatic adenocarcinoma, and other lesions. Immunocytochemically, CEA and Ki67 do not appear to be discriminate, but P53 may be of value in distinguishing BAC from CLA. Attention to subtle nuclear changes, characteristic grouping, cellular arrangement, and P53 reactivity could enable cytopathologists to accurately diagnose BAC.

RESUMEN

OBJECTIVE: To investigate the impact of pathologists' immediate evaluation of fine needle aspiration biopsy (FNAB) on increasing diagnostic yield and decreasing related expenses. STUDY DESIGN: All FNABs performed at our 420-bed hospital between January 1992 and December 1994 were reviewed. The 1992-1993 FNABs were all performed without pathologist attendance. Smears were wet fixed in 95% alcohol and later stained by the Papanicolaou or hematoxylin and eosin methods. The remaining aspirated material was collected in Saccomano's preservative, and a cell block was made. Nearly all the 1994 FNABs were performed with the pathologist present; he examined air-dried, Diff-Quik-stained smears for preliminary evaluation of the aspirate. An average of three passes were done. The rest of the procedure was as usual. RESULTS: The total number of 1992-1993 FNABs was 227 (108 + 119); of them, 104 (46%) were inadequate for diagnosis. In contrast, the 1994 FNABs totaled 169, with only 40 (24%) inadequate for diagnosis. The vast majority of the aspirates were done on deep-seated lesions under computed tomography (CT) guidance. CONCLUSION: The results of our experience indicate that on-site evaluation by a pathologist greatly increases the diagnostic yield. Another advantage is the significant financial savings as compared to excisional tissue biopsy. In general, the expenses of a CT-guided FNAB (e.g., pancreas) average around $1,400, while charges for excisional biopsy under general anesthesia with a subsequent two- to three-day hospitalization average about $7,720.

RESUMEN

BACKGROUND: Myelolipoma is a benign tumor composed of mature adipose tissue and hematopoietic cells. Although they are commonly found in adrenal glands, extraadrenal myelolipomas (EMLs) are rare but well documented. They have been found in various sites, including mediastinum, liver, stomach, lungs, pelvis, spleen, retroperitoneum, presacral region and mesentery. EMLs must be distinguished from extramedullary hematopoieses, which are also composed of hematopoietic elements but may lack adipose tissue and are associated with anemia and marked bone marrow hyperplasia. CASE: We describe a case of a pleura-based, extraadrenal myelolipoma in a 53-year-old female with unremarkable bone marrow findings that were initially encountered on fluoroscopy-guided fine needle aspiration (FNA). One year later the mass was removed via open thoracotomy. It showed typical EML features histologically. CONCLUSION: EML manifests on aspiration cytology as a cellular specimen with numerous trilineage hematopoietic cells and a variable proportion of mature adipose cells. To our knowledge, FNA cytology of EML has not been found in this location before. Aspiration biopsy offers a simple and reliable method for the diagnosis of EML in the presence of appropriate clinical settings.

RESUMEN

OBJECTIVE: To evaluate the efficacy and accuracy of fine needle aspiration biopsy (FNAB) in the diagnosis and recognition of pancreatic neuroendocrine tumors (NETs). STUDY DESIGN: The study group consisted of six cases of pancreatic tumors correctly diagnosed or strongly suggested to be NET based on fine needle aspiration biopsy (FNAB) cytology and was retrospectively reviewed. Also reviewed and examined were the immunocytochemical (ICC) stains applied to five of the aspirates and electron microscopic (EM) study done on one case. RESULTS: Five cases were collected by computed tomography (CT)-guided aspiration, and one case was obtained intraoperatively by the surgeon. All six cases showed characteristic cytomorphologic features sufficient for their recognition and separation from pancreatic adenocarcinoma and other lesions. The ICC staining results and EM study were very helpful in confirming the cases' neuroendocrine cell origin. Histologic confirmation was available for four cases. CONCLUSION: Intraoperative and CT-guided FNAB of the pancreas is a valuable method in the recognition of NET of the pancreas, particularly when coupled with ICC studies and appropriate clinical and radiologic settings.

RESUMEN

Granulocytic sarcoma (GS), or chloroma, is a rare extramedullary tumor composed of immature myeloid cells. It most commonly involves bone, soft tissue, lymph nodes and skin and develops during the course of or preceding myelogenous leukemia (ML). Involvement of other organs has been rarely reported including ovary, uterus and cervix, lung and the gastrointestinal tract; however, GS presenting as upper and lower gastrointestinal (GI) bleeding from ulcerated gastric mass and concurrent bleeding vaginal mass is an unusual rare manifestation of GS. We describe a case of GS in a 70 year old black woman who presented with a bleeding "lump" in the vaginal wall and suffered fatal GI bleeding from an ulcerated gastric lesion. She was diagnosed with myelodysblastic syndrome a few months earlier. From the review of the available English literature, this is a unique presentation of GS. It is important to include this entity in the differential diagnosis when encountering GI bleeding particularly in a patient previously diagnosed with myeloid leukemia or preleukemia. The importance of Naphthol Chloracetate Esterase (NCAE) stain and lysozyme immunoperoxidase stain in establishing the diagnosis is breifly discussed.

RESUMEN

The effect of salicylates or indomethacin usage during viral infection was investigated in a murine model of coxsackievirus B3 myocarditis. Eighty-two 3-week-old CD1 mice received 3 x 10(5) median tissue culture infective dose (TCID50) of coxsackievirus B3 intraperitoneally. Then they received salicylates, indomethacin, or saline solution daily for 10 days. Mortality, viral and antibody titers, interferon levels, and pathologic changes in the heart were compared. Mortality (2/33, 4/15, and 0/34, respectively) and virus titers (10(4.72), 10(4.78), and 10(3.4) TCID50, respectively) were higher, interferon levels (300, 267, and 980 IU, respectively) were lower, and pathologic changes were worse in treated animals (antibody titers were similar). These findings indicate that nonsteroidal anti-inflammatory agents adversely affect the course of acute coxsackievirus B3 murine myocarditis. Determination of the pathogenesis of this deleterious effect requires thorough evaluation of virus-host interactions.

RESUMEN

A 69-year-old man presented with protracted necrotizing pharyngitis requiring prolonged antibiotic therapy. During immunologic evaluation he was found to have IgA multiple myeloma, low complement component C1q and extrinsic defect of neutrophil chemotaxis. The severity of his pharyngitis correlated with myeloma activity implying a causal relationship. The characteristics of the illness strongly suggest that it is related to the acquired defect in neutrophil chemotaxis. This case represents a previously undescribed infectious complication of multiple myeloma.

RESUMEN

The effect of captopril on coxsackievirus B3 murine myocarditis was investigated. Thirty-two, 3-week-old mice were infected with coxsackievirus B3 on day 0 of the study, then randomized into a placebo group or a captopril group starting on day 3 of infection. On day 9 of infection, the mice were put to death. Hearts were weighed and processed for light microscopic examination. Heart weight was 125 +/- 19 mg in the control group versus 102 +/- 14 mg in the captopril group (p less than 0.0003). Amount of necrosis as a percentage of left ventricular section was 3.5% (2.0% to 7.5%) in the placebo group versus 2.0% (0.0% to 5.0%) in the captopril group (p less than 0.01). The amount of dystrophic calcification was 5.0% (0.0% to 27.5%) in the placebo group versus 1.3% (0.0% to 20.0%) in the captopril group (p less than 0.01). The extent of the histopathologic involvement by planimetry was 10.2% in the placebo group versus 5.4% in the captopril group (p = 0.052). We conclude that captopril is beneficial in decreasing left ventricular mass and the amount of myocardial necrosis and calcification in the short term in the murine myocarditis model.
