## Abstract

Introduction. The aim of the presented observational case series was to evaluate the experience in treating patients with community-acquired pneumonia (CAP) within integrative medicine, particularly anthroposophic medicine in a well-experienced and specialized unit. Patients and Methods. Patients with proven CAP were evaluated (CAP-study group) based on a retrospective chart review. To estimate the severity of pneumonia, the pneumonia severity index (PSI) was applied. Treatment efficacy was evaluated regarding body temperature, CRP level, leukocytes blood count, the need to be treated on ICU, and mortality. Results were compared with the inpatient data of the Pneumonia PORT Validation Cohort. Results. 15/18 patients of the CAP-study group belonged to risk class groups I–III (low and moderate risk), 2 patients to risk class IV, and one patient to risk class V (severe pneumonia). 16/18 patients were treated with anthroposophic medicine only and 2/18 got additionally antibiotic therapy (both of risk class IV). A significant reduction of body temperature, CRP level, and leukocytes blood count has been obtained by applying anthroposophic medicine, while neither complications nor pneumonia-related death occurred. Compared with the control group there was no significant difference in mortality rate, whereby no patient had to be treated on the ICU, but the duration of hospital stay was significantly longer in the presented series. Conclusion. Inpatient treatment of CAP with anthroposophic medicine without the use of antibiotics may achieve reasonable results in selected cases. Additional larger sized prospective controlled trials should further clarify the role of AM in the treatment of CAP.

## Body

## 1. Introduction

Optimal treatment of pneumonia plays a critical role in temporary medicine regarding morbidity and mortality [1–4]. In Germany, annual occurrence of pneumonias accounts for 400000 to 600000 patients, with an inpatient treatment rate of 30–50% [5]. Lethality amounts to 0.6% among outpatients and from 13 to 14% among inpatients whereby a significant age dependency is typical [4, 6].According to treatment guidelines, applications of antibiotics or other specific agents are strongly recommended. The aim of these standard treatments is to eliminate the causative agent (bacteria, viruses or mycoides, etc.) [4]. With increasing resistance to antibiotics [7–11], alternative treatment options are under debate. Moreover, the increasing request of patients on alternative treatment options [12–22] as well as cumulating data which might indicate a potential anticancerous role of acute inflammatory diseases and/or an adverse effect in antibiotic treatment [23–31] is triggering the discussion regarding treatment efficacy. In contrast, some approaches of integrative medicine primarily intend to support the human resources of recovery for curation (“aspect of salutogeneses”), while reducing or eliminating the causative agents (bacteria, viruses, or mycoids) becomes a secondary result only.However, data on treatment efficacy in pneumonias including complementary and alternative medicine (CAM)—in particular anthroposophic medicine (AM)—are limited.The aim of the presented study is to evaluate the treatment experience in applying anthroposophic medicine on a specialized and experienced unit with focus on the treatment of pneumonia.


## 2. Patients and Methods

Patients with proven diagnosis of community-acquired pneumonia (CAP), according to current guidelines [4], who were treated within the Department of Homeotherapy in Heidenheim between March 1999 and September 2001 were registered and consecutively divided into five subgroups. There were no further selection criteria, despite the willingness and consent of the patients, who were requesting integrative treatment. The Department of Homeotherapy in the Hospital of Heidenheim (Teaching Hospital of the University of Ulm, Germany) looks back on a 65-year experience in practising anthroposophic medicine (AM) including a broad spectrum of different applications within the scope of integrative medicine (IM). The concept of integrative medicine seeks not to weigh up conventional and alternative medicine against each other but to optimize both forms of treatment while intending an individualized approach [14–16, 21].Chart review was carried out focusing on the following parameters: initial clinical symptoms, radiologic features, blood sample tests, and clinical followup. Clinical data were retrospectively reviewed based on the hospital records including medical history and on results from the contributing radiologists and laboratory.According to current guidelines [4] the diagnostic criteria for CAP were the clinical picture of an acute pneumonia, such as possible fever, shivering, cough, phlegm, sputum, chest pain, dyspnea in association with increased leukocyte and/or CRP levels, and newly manifest infiltration in a chest X-ray [4]. Patients with atypical manifestations, particularly elderly people, were also included if a clinical change occurred, like confusion or mobility impairment which could not be explained by any other reason, but at the same time a newly manifest infiltrate had to be spotted on the chest X-ray [4]. All patients who did not fulfill these criteria, who had hospital-acquired pneumonia (HAP), or who had immune deficiency were excluded. Also, lost of followup was a reason for noninclusion.Results of chest X-rays were reviewed by two—and for this case series reevaluated by additional one—independent consultant radiologist(s) who were blinded concerning prior diagnosis but confirming radiological signs of pneumonia.In order to reduce potential coaffecting circumstances five different groups were differentiated (Figure1).Figure 1
Flow chart of the inclusion and exclusion processes. *Other reasons for exclusion: patients with an immunodeficiency (n=1), patients lost of followup (n=1, this patient wanted to be moved to a hospital closer to home).Group 1 includes patients pretreated with antibiotics before admission to the Department of Homeotherapy; group 2 includes patients with an acute cardiac decompensation and a congestive pneumonia (treatment of heart failure improves usually pneumonia too in these cases); group 3 includes patients in palliative care. All other patients were defined as theCAP-study group: treated either with AM only (group 4) or additionally with antibiotics (group 5).Pneumonia severity index (PSI) was applied in order to indicate the severity level of pneumonia, divided into five risk classes [32–35] (Table 1).Table 1

∑ 91–130 = risk class IV
∑ >130 = risk class VAs shown in Table1, patients are scored between −10 and +30 points for the different parameters. Patients were assigned to a risk class (risk class II, III, IV, or V) according to the number of points they scored. Identifying patients in risk class I is extensively described by Fine et al. [32]. Fine et al. had derived a prediction rule for the prognosis by analysing data of 14, 199 adult inpatients with CAP. This risk score was validated on 38,039 adults hospitalized and data of 2287 inpatients and outpatients with community-acquired pneumonia.In case of missing classification data, only the available information were incorporated into risk assessments. Consecutively, in these cases the patient was classified at a lower risk category and therefore rather understaged. The amount of missing data was documented.Patients were informed about different treatment options available and about the estimation of the treating physician, whether antibiotics were needed or not. Treatments were carried out only in agreement with the patients (informed consent). The individualized treatments were evaluated gathering information on which anthroposophic drugs and external medical applications like compresses, packs, and poultices each patient received or if the patients were treated with antibiotics and/or antipyretics. The finding process for each individual patient is based on a holistic perspective on man and earth according to the view point of anthroposophic medicine.For follow-up evaluation the number of leukocytes, the CRP level, the course of body temperature as well as the need for treatment on ICU, and the 30-day mortality in hospital were documented.Forstatistical analysist-test for paired samples and chi-square test were applied. Missing data were replaced with the last observed value carried forward (LOCF). Calculations were performed using WinSTAT (R. Fitch Software, Germany), SAS/STAT (SAS Institute Inc., Cary, NC, USA) and SPSS (SPSS Inc., Chicago, IL, USA). A P value of <0.05 was considered statistically relevant. Results of the presented data were compared with data of the inpatient Pneumonia PORT Validation Cohort [32] in regard to mortality rate, the necessity to treat patients in ICU and the length of stay in hospital. statistical analysis were conducted by Thomas Ostermann, Ph.D. M.S., Professor for Research Methodology and Information Systems in Complementary Medicine, Faculty of Health, Department of Medicine, Center for Integrative Medicine, Witten/Herdecke University, Germany.


## 3. Results

Extending thirty months, 48 patients with “pneumonia” were admitted to the department of Homeotherapy in Heidenheim and treated based on anthroposophic medicine. 26 patients (19 f : 7 m) with a mean age of 65.5 years (19–90 a; SD 19.84) fulfilled the inclusion criteria “community-acquired pneumonia” (see Figure1). The comorbidities are outlined in Table 2.Table 2

1218 of these patients showed no major comorbidities, which otherwise might mainly influence the course of the pneumonia (such as congestive heart failures, immunodeficiency), and therefore these 18 patients became the main focus for the evaluation of anthroposophic medicine (CAP-study group, see also Figure1). The distribution of risk classification according to the pneumonia severity index (PSI) is outlined in Table 3.Table 3

2On the whole 494 items could have been evaluated for calculating the PSI while 65 were missing. That counts for a missing data rate of 13.1%, from 0 to 4 data tops per patient (median 2.0). The pO2 and pH value were the most common missing data, followed by respiratory rate and in few cases glucose and blood urea nitrogen.16/18 patients were treated applying anthroposophic medicine and without the use of antibiotics; in 2/18 patients, antibiotics were applied in addition. The individualized application plan for each patient in regard to anthroposophic medication and treatment is outlined in Table4.Table 4

This table shows the individual therapy plan of each patient. Peroral (p.o.) and subcutaneous medication (s.c.) is outlined as well as external applications (Ext.). We omitted the illustration of convential co-medication. If the applied homeopathic potencies differed from the described in the headline, it was particularly outlined in the table. CAP-study group are bold.With regard to parameters which indicate efficacy of treatment (in these seriesAM treatment) the body temperature, the leukocyte blood count, and CRP levels were documented. 70% of patients were free of fever after 72 hours (3d) consecutive to the onset of AM treatment. The maximal duration of febrile body temperature amounted to 10 days (Figure 2). In one patient (who has got additionally antibiotic therapy), allopathic antipyretic therapy (Novaminsulfon acid) was applied per os over a period of 5 days. Despite two patients (out of palliative care group 3) in all patients a highly significant decrease of initially elevated CRP levels was observed (Figure 3 and Table 5) beside normalization of leukocyte blood count in cases of initial leukocytosis (Tables 8 and 9).Table 5
Statistical analysis of CRP course.
This table shows the statistical analysis of CRP decrease from the initial to the second and third value and from the second to the third value.T-test for paired samples was applied. (Initial, 1–3 days (1), 4–9 day (2), End of Treatment (3))Figure 2
Course of temperature in group 4 (patients with AM only in the CAP-study group). Figure2 shows the number of patients with body temperature above 38°C within the first ten days.Figure 3
Course of CRP in group 4 (patients with AM only in the CAP-study group). CRP value 1–3 days shows the highest CRP level within the first three days, CRP value 4–9 the lowest value within this time span, and CRP before admission value at the end of treatment in hospital.The mean duration in hospital within the CAP-study group (n=26) was 20.2 days (Table 7). None of these patients needed to be treated on the ICU, compared to 9.2% within the control group, ranging from 4,3% to 5,9% in lower risk classes I–III, 11,4% in risk class IV, and 17,3% in risk class V whereby the duration in hospital is ranging from 5 to 11 days [32].On the whole, one patient died for not pneumonia-related reasons (out of palliative care group 3), within the patients who fulfilled the inclusion criteria (groups 1–5,n=26; 3.8%). In comparison to the control group (mortality rate of 8%), no significant difference (P=0.44) within statistical analysis, using the chi-square test, was observed (Table 6). Two of the primarily excluded patients with HAP (n=22, see Figure 1), who belonged to palliative care patients, died (age 90 and 91). In order to estimate whether a selection bias might influence not seeing a significant difference in comparison to the control group chi-square-test was applied also on the whole collective included (excluded patients plus groups 1–5, n=48) obtaining a mortality rate of = 6.3% compared to 8.0% in the PORT control group (P=0.69), indicating also no significant difference.Table 6

## 4. Discussion

From the background of achieving high cure rates, antibiotic therapy for community-acquired bacterial pneumonia is the treatment of choice today. However with increasing resistance to antibiotics, unpleasant adverse effects and not least with rising request of patients to be treated within the scope of an integrative approach, alternative treatment options are under debate. Moreover, available data in this context is limited within the established medical literature. Therefore, the aim of the presented observational case series is to evaluate the experience in treating community-acquired pneumonia (CAP) with anthroposophic medicine (AM) within a highly specialized and well-experienced medical unit. The data of the presented observational case series are documenting the availability of an integrative treatment option for the treatment of CAP in hospital with good and comparable results in certain cases, in the context of such a specialized medical unit. Herewith, the presented study reports on unique data on a very relevant topic. However, due to the retrospective study design, the small number of patients, and a mutually not to be underestimated selection bias, the weight of conclusions for future treatment strategies in bacterial pneumonias is limited. Therefore, controlled prospective trials remain to further clarify the role of integrative medicine in the treatment of pneumonias.Out of 48 patients with pneumonia, 26 had CAP, and 18 patients out of these were primarily treated with AM (CAP-study group, see Figure1 and Table 3), while two of the latter got additional antibiotic treatment during their course. The individual anthroposophic treatment (as outlined in Table 4) did significantly reduce body temperature, CRP level (P=0.03), and white blood cell count, while no statistical difference with regard to morbidity or mortality was observed (P=0.44; P=0.69), but a 2-3-fold longer hospital stay was necessary in comparison to the conventional standard antibiotic treatment of bacterial CAP in the control group [36] (Table 7). This is in line with published data concerning the antibiotic treatment of CAP [37], while there are no comparable studies on CAM or AM regarding inpatient treatment of CAP. Within the CAP study group, there was no pneumonia-related death observed, and none of the patients needed to be treated on the ICU. Anyhow, it is questionable, whether the investment of a multifold longer hospital stay—at least with regard to the costs—might be at any time convincing in order to support the integrative approach in the management of pneumonia. However, despite the economical aspect at first step, which favours the antibiotic treatment, there are also critical data on long term adverse effects in context with antibiotic and antiinflammatory treatments published [27–31, 38], such as pro-cancerous effects and/or relations to the genesis of immunological disorders, for example, in melanoma of the skin [27], in breast cancer [31], and also in hemato-oncological diseases like acute lymphatic leukaemia [30] or non-Hodgkin lymphoma [31]. The use of antibiotics and antipyretic drugs seems to play a major role in the development of allergies and/or autoimmune diseases, too [38]. But these long term sequelae of antibiotic and antipyretic/anti-inflammatory drugs as well as a potential benefit by using alternative approaches are very difficult to evaluate and therefore remain to be further investigated in future studies. From the view point of integrative medicine, the intention to mobilize human natural resources of recovery (salutogenic approach) should reduce adverse events or any other harms to the patients but still remain to be proven yet. Moreover, the rate of recurrence might be a supplemental challenging issue with regard to treatment efficacy and sustainability. Whether the character of approach (integrative and salutogenic or allopathic) may substantially influence the recurrence rate of pneumonia or other sequelae diseases should be consecutively of interest, also regarding the economic debate.In addition, also multiresistance of pneumonia inducing bacteria has become a rising and challenging issue at present [7–11], which might be solved at least in selected patients who could be treated with anthroposophic medicine instead of antibiotics. Consecutively, selection criteria which may indicate secure application of integrative treatment options remain also to be further evaluated. In the presented course of patients with CAP the indication to additionally apply antibiotics appeared whenever a patient did not show any sign of recovering within three days after onset of treatment (like in two patients of the CAP study group) or if a progressive deterioration was obvious regarding parameters, such as dyspnea, body temperature, CRP level, or white blood cell count.With regard to the well-validated classification of CAP into different levels of severity (PSI:  pneumonia severity index), 15/18 patients of the CAP-study-group belonged to lower risk classes I–III, and all of these were treated with AM only (Table3). Two patients of risk class IV were treated with antibiotics in addition to AM. Finally one patient classified into risk class V could also be treated with AM only. These data may show the practicability of AM in the treatment of pneumonia in principle, but neither do the low number of patients and the retrospective design allow to conclude reliable expectations on treatment results nor do they indicate certain limitations of the anthroposophic therapeutic concept. Therefore controlled prospective studies remain to be performed in order to clarify strengths and limitations of the integrative approach in the treatment of pneumonia.Anyhow it is worth to notice that even severe pneumonias might be approachable by applying AM only, as indicated by the patient classified in risk class V. This is in accordance with recently published data reporting a successful treatment course in a case of a 96-year-old female with severe pneumonia, lung abscess, and associated septicemia, treated with AM only (without antibiotic) [39]. Therefore, it needs years of experience as well as a time-intense dedication of the attending physicians and care team whereby external administration is mandatory in anthroposophic treatment of CAP and moreover the competence in executing the task.Anthroposophic medicine is based on modern temporary natural science and medicine by aiming to extend these achievements with an additional holistic view on man, earth, and cosmos including the four aspects of elements and therefore intends to search for a specific individual treatment for each patient [22, 40]. AM is not intending to get in competition with modern temporary medicine but rather extending and eventually enriching it. Within a time of rising professionalised medicine with standardized clinical pathways there is almost no space for an individual treatment finding. The sketched background of AM is ordinarily excluded in conventional medicine, but within the presented case series it was intended to include all these mentioned dimensions of AM. It would be worth to further outline this characteristic process of therapy finding in an extra presentation. Further declaration of AM in detail would burst the scope of this paper and therefore remains to be outlined at other spaces.Finally, within the context of the presented data it needs to be pointed out that integrative medicine—and as in the presented case series AM in hospital—needs a great personal effort, due to its time-intense care procedures that call for a high competence, and this might at least partly justify a prolonged hospital stay. At present, the reported data do not allow to indicate the use of anthroposophic medicine in the treatment of CAP in general. But the presented data are encouraging to further evaluate the role of integrative medicine within the treatment of CAP regarding efficacy, security, economy, and sustainability.This case series contributed towards showing the usefulness of AM in the context with inpatient treatment of CAP. The data shows that it is possible to put selected patients with CAP on a comfortable path of recovery by treating them with AM only. Because health conscious patients in particular opt for CAM, and, in our case AM, we cannot exclude the aspects of a selection bias towards healthier patients in the presented series. Therefore, it would be particularly useful to have a larger sized controlled prospective study on the treatment of pneumonia patients with AM.
