    Notes: Summary The clinical value of different classification systems of HIV-infection has been examined in a cohort of 99 HIV-infected individuals. AIDS-related complex (ARC), Walter-Reed (WR) stage 5 and Centers for Disease Control (CDC) group IV without AIDS cases were equally capable of identifying patients with bad prognosis: Out of 12 patients progressing to AIDS, 9 WR 5, 7 CDC IV and 7 ARC. Prognostic parameters (Erythrocyte sedimentation rate, Haemoglobin, Leucocytes, CD4-lymphocytes and Beta2-Microglobulin) did not differ in the three groups. However, there were great differences in the frequency of patients infected by homosexual contacts and of intravenous drug-abusers. Drug-abusers were more often seen in the ARC-group, whereas there was a slight dominance of homosexuals in the WR 5-group (and a marked preponderance in the AIDS-group). Using 3 different ARC-definitions we found an ARC-frequency of 10%, 24% and 41% in our cohort. Thus the great variability of the ARC-concept could be demonstrated. In conclusion we believe that for the purpose of clinical documentation and studies the ARC-concept is unnecessary. Further studies have to evaluate other classification systems (Walter-Reed, CDC) or to establish new ones.

    Notes: Summary Eleven Human Immunodeficiency Virus 1 (HIV1)-infected patients (10 male, 1 female; age 23–51 years (median 36); 10 male homosexuals, 1 IV drug abuser; WR3 1 patient, WR5 5, WR6 5) with intestinal Cytomegalovirus (CMV)-manifestations were compared with a group of 78 HIV1-infected patients in respect to their clinical, immunological and virus-serological data and the results of the histological and microbiological examination of endoscopically obtained biopsies. No differences were observed on age, sex, risk of infection, stage and immunological status. Bloody diarrhea was most important in discriminating CMV-colitis and non-CMV-related intestinal manifestations. Dysphagia and other symptoms occurring in patients with CMV-esophagitis were not able to predict CMV-esophagitis specifically. 6 of 11 patients with serological findings consistent with an active CMV-infection had no detectable CMV-manifestations; 6 of 11 patients with intestinal CMV-manifestations did not show serological findings suggestive of active CMV-infection. Ulcerative alterations of intestinal mucosa represent the most powerful indicator of intestinal CMV-disease in endoscopical examination. Only in two patients, ulcerative alterations were seen without diagnosis of CMV-disease being established. CMV was isolated in one of 11 patients, in two patients CMV was isolated from biopsies of unchanged mucosa. Simultaneous infection by HSV and CMV was detected in three patients, in one patient in the same localisation. Histology revealed inclusion bodies in 8 of 11 patients with intestinal CMV-disease, in no case inclusion bodies were seen without CMV-disease.

    Notes: Zum Thema In dieser Übersicht wird über den Einsatz von Proteaseinhibitoren bei HIF-Infektion berichtet und der diesbezügliche Therapiestandard aufgezeigt. Im Mittelpunkt der Betrachtungen stehen aber – und hier seien die nicht spezialisierten Leser besonders angesprochen – methodische Probleme klinischer Studien, in erster Linie die Fragen: Wie soll man die medikamentöse Behandlung prüfen? Was kann man von einer Prüfung erwarten? Welche Studienmethoden wären wünschenswert aber auch ethisch vertretbar, um bei einer Krankheit, die unbehandelt rasch und tödlich verläuft, therapeutisch verwertbare Ergebnisse zu erhalten? Gerade am Beispiel der HIV-Infektion, lassen sich prinzipielle methodische Probleme klinischer Studien erläutern.

    Description / Table of Contents: Zusammenfassung In 14 Episoden einer CMV-Erkrankung bei 13 HIV-infizierten Patienten wurde eine Kombinationstherapie mit Ganciclovir und Foscarnet in einer offenen, prospektiven, nicht randomisierten Studie durchgeführt. Alle Patienten (n=13, Alter 30–42, Median 34 Jahre; CD4+Lymphozyten 0–80, Median 10/µl; alle Stadium IV CDC) wurden über 3 Wochen mit 2 × 5 mg/kg/d Ganciclovir und 2 × 90 mg/kg/d Foscarnet behandelt. In sieben Episoden einer gastrointestinalen CMV-Erkrankung (Colitis fünf, Ösophagitis zwei) wurde eine Remission in fünf Episoden erzielt, bei CMV-Retinitis in sechs von sieben Fällen. Nephrotoxizität trat bei zwei Patienten auf, mäßige Hämatotoxizität bei acht Patienten, sämtlich reversibel. Die Wirksamkeit der Therapie ist ähnlich der Monotherapie, die Nebenwirkungen sind additiv.
    Notes: Summary An open prospective trial of combined ganciclovir and foscarnet therapy for 3 weeks was initiated in 14 episodes of severe CMV-disease in 13 HIV-infected patients (all CDC class IV, age 30–42, median 34 years, CD4+ cell count 0–80, median 10/µl). In seven episodes of gastrointestinal disease (five colitis, two esophagitis) remission of symptoms and mucosal changes was achieved in five. In seven episodes of retinitis, scarring was achieved in six. Renal toxicity was seen in two patients, moderate hematologic toxicity in eight patients. Overall efficacy was comparable to monotherapy; no new toxicities were seen with the combination of these two drugs.

    Description / Table of Contents: Zusammenfassung Eine intestinale Microsporidiose mitEnterocytozoon bieneusi konnte bei drei von 18 HIV-infizierten Patienten mit chronischem Durchfall durch elektronenmikroskopische Untersuchungen diagnostiziert werden. In zwei Fällen wurden alle bekannten Stadien des Entwicklungszyklus vonE. bieneusi in duodenalen Biopsien gefunden (Meronten, Sporonten, Sporoblasten, Sporen) wohingegen in einem Fall nur Meronten und Sporonten gesehen wurden. Die Sporen waren auch lichtmikroskopisch in Semidünnschnitten sichtbar. Zwei Patienten wurden mit Albendazol behandelt (2×400 mg/Tag für 4 Wochen), besserten sich jedoch nicht in ihrer Symptomatik. Diese drei Fälle einer intestinalen Microsporidiose unterstreichen das Konzept der weltweiten Verbreitung dieser Parasiten und belegen, daß sie auch in Deutschland häufiger vorkommen.
    Notes: Summary Intestinal microsporidiosis withEnterocytozoon bieneusi was diagnosed in three of 18 HIV-infected patients with chronic diarrhoea. In two cases all known stages of the life cycle ofE. bieneusi (merogonial plasmodia, sporogonial plasmodia, sporoblasts, spores) were found in duodenal biopsies by electron microscopical examination, whereas in the third case only merogonial and sporogonial stages were seen. Spores were also visible by light microscopy in semithin sections. Two patients were treated with albendazole (2×400 mg/day for 4 weeks) but showed no response. These findings underline the concept of the worldwide distribution of this parasite and verify that it is also frequent in Germany.

    Description / Table of Contents: Zusammenfassung In einer offenen randomisierten Studie wurde Foscarnet 90 mg/kg i. v. zweimal täglich über 3 Wochen in zwei verschiedenen Dosierungsschemata bei HIV-infizierten Patienten mit schweren gastrointestinalen CMV-Erkrankungen verglichen. Die erste Gruppe erhielt Foscarnet täglich, die zweite an 5 Tagen jeder Woche. 38 Patienten wurden randomisiert, davon waren 36 auswertbar (alle männlich, Alter 24–54, Median 40 Jahre, CD 4 µl/0–150, Median 10) Der Behandlungserfolg wurde anhand eines Scores von Symptomen, endoskopischem Befund und histologischer Beurteilung gemessen. In der Gruppe, die an 5 Tagen der Woche behandelt wurde, sprachen 10/16 (62%) auf die Therapie an, in der 7-Tage-Gruppe 13/20 (65%). Nebenwirkungen wurden in 13 Patienten der 5-Tage-Gruppe und in 15 der 7-Tage-Gruppe beobachtet. Die häufigsten Nebenwirkungen waren Abweichungen der Serum-Elektrolyte in beiden Gruppen, eine Patient entwickelte einen reversiblen Kreatinin-Anstieg. Wirksamkeit und Nebenwirkungen der 5-Tage-Therapie waren vergleichbar mit der Standardtherapie.
    Notes: Summary In a randomized open trial foscarnet 90 mg/kg b.i.d. 5 days for 3 weeks was compared to 90mg/kg b.i.d. daily in severe gastrointestinal cytomegalovirus disease in HIV-infected patients. Thirty-eight patients were randomized, 36 were evaluable (all male, age 24–54 years, median 40 years; CD4/µ10–150, median 10). Treatment efficacy was evaluated based on a score consisting of symptoms, endoscopic and histologic examination. In the 5-day treatment group 10/16 (62%) patients responded to treatment, in the 7-day treatment group 13/20 (65%), with symptoms resolving in most patients after 1 week. Side effects and adverse events were seen in 13 patients in the 5-day treatment group and in 15 patients in the 7-day treatment group. Laboratory abnormalities were common in both groups, in one patient reversible renal insufficiency developed. Efficacy and safety of treatment 5 days a week was comparable to the standard regimen.

    Notes: Abstract  The aim of the present study was to use small-subunit (SSU)-rRNA sequences of Isospora belli to design specific primer pairs and a hybridization probe for the detection of Isospora belli in human samples by PCR and Southern blot hybridization. PCR amplification with the primer pairs produced correct DNA fragments with target DNA from samples of Isospora belli-infected patients and from cloned SSU-rRNA of Isospora belli. The nature of the PCR products was confirmed by Southern blot hybridization. No amplification was seen with template DNA extracted from other parasites. Although Isospora belli infections can be easily diagnosed using light microscopy, molecular-based techniques may prove useful as an additional diagnostic tool.

    Notes: Abstract Raynaud's phenomenon is a common vascular side effect of chemotherapy drug regimens. Chemotherapy-induced Raynaud's phenomenon leading to acral gangrene has rarely been reported. In this report, one patient who developed gangrene after bleomycin and vincristine/vinblastine chemotherapy for AIDS-related Kaposi's sarcoma and another HIV-infected patient who exhibited symptoms of severe Raynaud's phenomenon related to the same regimen are presented. Because the combination of bleomycin and vinca alkaloids is commonly used for the treatment of AIDS-related Kaposi's sarcoma, clinicians should be aware of the risk of provoking acral necrosis in patients who develop Raynaud's phenomenon under chemotherapy. The literature is reviewed, and clinical symptoms, pathophysiology, and treatment options are discussed.

    Notes: Abstract The taxonomic positions of Isospora belli and other members of the genus Isospora are controversial. We determined the small-subunit ribosomal RNA of I. belli and used this sequence in combination with other coccidian RNA sequences for analysis of the taxonomic position of I. belli. The phylogenetic trees we obtained provide molecular evidence for three clades within a monophyletic group that represents the suborder Eimeriina. The clade containing I. belli consists of tissue-cyst-forming coccidia (Toxoplasma and Neospora) and members of the genus Isospora (I. ohioensis, I. suis, I. belli). The second clade, representing a sister clade of that containing the Isospora species, contains members of the genus Sarcocystis. The third one consists of members of the family Eimeriidae, including Eimeria and Cyclospora species. This shows that although I. belli as well as other members of the genus Isospora belong to the suborder Eimeriina, the family to which they belong is not Eimeriidae but rather Sarcocystidae. We suggest that the genus Isospora should be removed from the family Eimeriidae and placed into the family Sarcocystidae within the suborder Eimeriina.
